IA-5	25th day of month	5.98%	LIBOR + 0.65%*	6%*	0.65%
IA-7	25th day of month	0.02%	5.35% - LIBOR	5.35%	0%

Class IA-5 will benefit from a yield maintenance agreement with The Bank of New York that may provide additional payments to holders of class IA-5 certificates for distribution days for which LIBOR is greater than 5.35%.

(4)	The notional balance of class IA-7 on any distribution day will equal the principal balance of class IA-5 on that distribution day.

(5)	Classes IA-PO and IIA-PO are ratio-stripped PO classes and do not bear interest.

(6)	After the first distribution day, ratio-stripped IO classes IA-IO and IIA-IIO will have a notional balance on any distribution day equal to the aggregate scheduled principal balance of the premium loans of the related pool on the last day of the preceding month.

(7) Each ratio-stripped IO class will accrue interest on its notional balance at an annual rate equal to the weighted average net loan rate of the premium loans in its related pool minus the target rate for that pool. The initial annual interest rates for the ratio-stripped IO classes are expected to be:

Class IA-IO	0.6242223174%
Class IIA-IO	0.5115431514%

12.3 Target rate

The per annum target rates for the pools are

pool I: 6%

pool II: 5.75%

Each class other than any ratio-stripped IO or ratio-stripped PO class is a target-rate class.

12.4 Ratio-stripped IO and PO classes

Each of classes IA-IO and IIA-IO is a ratio-stripped IO class, and each of classes IA-PO and IIA-PO is a ratio-stripped IO class.

12.5 Loss limits

There is no initial special hazard loss limit, initial bankruptcy loss limit, or initial fraud loss amount.

12.6 Denominations

The denominations of

· the senior class certificates and the class B-1 through B-3 certificates are initial principal (or, for any IO classes, notional) balances of $1,000 and any whole dollar amount above $1,000,

· the class ▇-▇, ▇-▇ and B-6 certificates are $100,000 initial principal balance and any larger integral multiple of $1,000, and

· the residual certificates are percentage interests summing to 100%.

If the initial principal or notional balance of a class is not a permitted denomination for a certificate of that class, one certificate of the class may be issued in a different denomination.

12.7 The mortgage loans

The mortgage loans in the Trust Fund are identified on the mortgage loan schedule. The mortgage loans in

· pool I will consist primarily of 20- to 30-year fixed-rate conventional one- to four-family mortgage loans, and

· pool II will consist primarily of 10- to 15-year fixed-rate conventional one- to four-family mortgage loans.

12.8 Right to repurchase

CMSI cannot exercise its right to repurchase the mortgage loans pursuant to section 9.1(a) of the Standard Terms unless

· the aggregate scheduled principal balance of the mortgage loans is less than $31,400,372.86 at the time of repurchase, and

· if there is an insured class outstanding and the exercise of such repurchase right would result in a draw under any certificate insurance policy, the Insurer has previously consented.

12.9 Book-entry and definitive certificates

All senior class certificates (other than the ratio-stripped IO certificates) and the class B-1 through B-3 certificates will be issued as book-entry certificates. Book-entry certificates for a class or a group of classes will be represented by one or more certificates issued in the name of a depository. The ratio-stripped IO certificates, the class B-4 through B-6 certificates, and the residual certificates will be issued in fully registered certificated form (definitive certificates).

12.10 Voting interests

Each IO class will have a 1% voting interest. The remaining voting interest will be allocated to the other classes in proportion to their principal balances. The voting interest of any class will be allocated among

the certificates of the class in proportion to the certificates’ principal or notional balances, except that an Insurer will be entitled to the voting interest of an insured class for as long as the insured class is outstanding and the Insurer is not in default..

12.11 Cash deposit

No cash will be deposited into the certificate account on the closing date.

13	Principal balances

13.1 Class balances

Each class that is not an IO class will have a principal balance, and each IO class will have a notional balance. The principal or notional balance of multiple classes (e.g., the senior classes) is the aggregate of the principal or notional balances of those classes.

The initial principal or notional balance for each class is stated in “The series - General terms for classes” above. The principal balance of each class that is not an IO class will be adjusted on each distribution day, as described in “Adjustments to class balances” below.

The notional balance of a ratio-stripped IO class for any distribution day after the initial distribution day will equal the aggregate scheduled principal balance of the premium loans of the related pool on the last day of the preceding month.

The notional balance of each IO class that is not a ratio-stripped IO class will be adjusted on each distribution day as described in “The series - General terms for classes” above.

13.2 Certificate balances

The sum of the initial principal or notional balances stated on the certificates of each class will equal the initial principal or notional balance of the class.

Except as may be provided in “Retail classes” below, the principal or notional balance of each certificate will equal its proportional share, based on the initial principal or notional balances stated on the certificates of the class, of the principal balance or notional balance of the class to which the certificate belongs.

14	Allocations

14.1 Interest allocations

Beginning on the cut-off date, each class (other than any PO class) will accrue interest for each month on its principal or notional balance at the certificate rate for the class stated in “The series - General terms for classes” above. In calculating accrued interest,

· a class’s principal or notional balance on the last day of a month will be considered to be the class’s principal or notional balance on every day of the month, and

· interest for a month will be calculated at 1/12 of the certificate rate, regardless of the number of days in the month.

Example: Suppose that on January 1, a class has a principal balance of $1,020,000 and a certificate rate of 6% per annum. On the January distribution day, the class’s principal balance is reduced by $20,000. As a result, the principal balance of the class on January 31 is $1 million. Then the interest accrued for the class during January (which is paid on the February distribution day) is 1/12 of 6% of $1 million = $5,000; that the principal balance of the class was greater than $1 million before the January distribution day, and that January has 31 days, are irrelevant.

A class’s interest allocation for a distribution day is the sum of

· the class’s current interest allocation for the distribution day, consisting of the class’s accrued interest for the preceding month minus the class’s proportional share, based

on accrued interest, of (1) any non-supported prepayment interest shortfall, and (2) the interest portion of any non-subordinated losses, for the preceding month,

· plus any excess of the class’s interest allocation for the preceding distribution day over the interest distributed to the class on that preceding distribution day (the interest allocation carryforward from that distribution day). (If the class is an insured class, for purposes of calculating allocations and distributions to the class, the interest allocation carryforward from a distribution day will be reduced by any payments to the class from the Insurer relating to the interest allocation carryforward, but will not be so reduced for purposes of effecting the Insurer’s subrogation rights relative to the interest portion of any insured payment.)

14.2 Principal allocations

The principal allocation for a distribution day is:

(a) for any ratio-stripped PO class, the sum for that distribution day of scheduled and unscheduled principal payments on its PO strip for that distribution day.

(b) for the senior target-rate classes collectively, the sum for that distribution day of

· the target-rate class percentage for the senior target-rate classes of scheduled principal payments on the target-rate strip, and

· all unscheduled principal payments on the target-rate strip allocated to the senior target-rate classes pursuant to “ - Unscheduled principal” below.

The principal allocation for the senior target-rate classes will be allocated among the individual senior target-rate classes pursuant to “Allocations among the senior classes” below.

(c) for each subordinated class,

· the class’s target-rate class percentage of scheduled principal payments on the target-rate strip for that distribution day,

· plus the class’s proportional share, based on the principal balances of the subordinated classes, of unscheduled principal payments on the target-rate strip for that distribution day that are not allocated to the senior target-rate classes pursuant to the preceding paragraph (b),

· plus or minus any amounts that are reallocated to or from the class pursuant to “- Maintenance of subordination” below.

14.3 Unscheduled principal

For each distribution day, the following percentage of unscheduled principal payments on the target-rate strip received during the preceding month will be allocated to the senior target-rate classes:

· 100% if the target-rate class percentage for all the senior target-rate classes on the distribution day exceeds the initial target-rate class percentage for all the senior target-rate classes.

· otherwise, and subject to the following proviso, the sum of (1) the target-rate class percentage for the senior target-rate classes, plus (2) the following percentage of the target-rate class percentage for the subordinated classes:

distribution days	percentage
1through60	100%
61through72	70%
73through84	60%
85through96	40%
97through108	20%
109 and after	0%

provided, that

· if the distribution day is one on which the percentage shown in the preceding table is to be reduced - that is, the 61st, 73rd, 85th 97th or 109th distribution day - and either the cumulative loss test or the delinquency

test described below are not satisfied, then the percentage will not be reduced on that distribution day or on any subsequent distribution day until both the cumulative loss and delinquency tests are passed, and

· if the cumulative loss test is not satisfied for a distribution day, the percentage of unscheduled principal payments allocated to the senior target-rate classes will be the greater of the percentage of unscheduled principal payments allocated to the senior target-rate classes for that distribution day calculated in accordance with the preceding rules of this section, or the percentage of unscheduled principal payments allocated to the senior target-rate classes for the preceding distribution day.

The cumulative loss test is satisfied for a distribution day if cumulative realized losses through that distribution day do not exceed the following percentages of the initial principal balance of the subordinated classes:

distribution days	percentage of initial principal balance of subordinated classes
61 through72	30%
73 through84	35%
85 through96	40%
97 through108	45%
109 and after	50%

The delinquency test is satisfied for a distribution day if CitiMortgage certifies to the Trustee that the average of the aggregate scheduled principal balance of mortgage loans delinquent 60 days or more (including, for this purpose, mortgage loans in foreclosure and real estate owned by the Trust as a result of mortgagor default) for that distribution day and the preceding five distribution days is either (1) less than 50% of the average of the principal balance of the subordinated classes for those distribution days, or (2) less than 2% of the average scheduled principal balance of all of the mortgage loans for those distribution days.

If there are composite and component subordinated classes, only the composite subordinated classes are considered in the cumulative loss and delinquency tests.

14.4 Maintenance of subordination

The subordination level for a class (other than a ratio-stripped IO class) is the sum of the class percentages of all classes that are subordinate to that class. If a class’s subordination level on the day before a distribution day is less than the class’s initial subordination level, then the class will have an impaired subordination level on that distribution day.

If a subordinated class has an impaired subordination level on a distribution day, then all principal originally allocated to the subordinated classes will be allocated to the most senior of the subordinated classes with an impaired subordination level and to those subordinated classes that are senior to the impaired class, in proportion to their principal balances, up to those classes’ principal balances, and any remainder will be allocated to the remaining subordinated classes, in order of seniority, up to those classes’ principal balances.

Example: Suppose that on a distribution day, (a) each of classes B-1 through B-6 had a principal balance on the preceding day of $1,000, (b) the aggregate principal allocation to the subordinated classes is $3,120, and (c) class B-2 has an impaired subordination level. Then on that distribution day

(1) the entire amount allocated to the subordinated classes will be allocated to classes B-1 and B-2, in proportion to their principal balances, up to their principal balances, and

(2) $1,000 of the remaining $1,120 will be allocated to class B-3, reducing its principal balance to zero, and

(3) the remaining $120 will be allocated to class B-4.

15	Allocations among the senior classes

15.1 Order of allocation among senior target-rate classes

On each distribution day before the subordination depletion date, the aggregate scheduled and unscheduled principal allocated to the senior target-rate classes of a group will be allocated to the individual senior target-rate classes of that group as follows:

Group I: Principal allocated to the group I senior target-rate classes from the pool I target-rate strip will be allocated sequentially as follows:

First, to classes ▇▇-▇, ▇▇-▇▇ and IA-12, the amounts determined under ‘‘NAS classes’’ below.

Second, to classes IA-2 through IA-4 and IA-8 through IA-10 sequentially as follows, until their aggregate principal balance is reduced to their aggregate planned balance for that distribution day as shown in “—PAC classes” below:

Concurrently to classes ▇▇-▇, ▇▇-▇ and IA-10, in proportion to their principal balances, until their principal balances are reduced to zero.

Sequentially to classes ▇▇-▇, ▇▇-▇ and IA-4, in that order, until their principal balances are reduced to zero.

Third, sequentially to classes IA-5 and IA-6, until their principal balances are reduced to zero.

Fourth, to classes IA-2 through IA-4 and IA-8 through IA-10 sequentially as follows, without regard to their aggregate planned balance:

Concurrently to classes ▇▇-▇, ▇▇-▇ and IA-10, in proportion to their principal balances, until their principal balances are reduced to zero.

Sequentially to classes ▇▇-▇, ▇▇-▇ and IA-4, in that order, until their principal balances are reduced to zero.

Fifth, concurrently to classes ▇▇-▇, ▇▇-▇▇ and IA-12, in proportion to their principal balances, until their principal balances are reduced to zero.

Group II: Principal allocated to the group II senior target-rate classes from the pool II target-rate strip will be allocated to class IIA-1 until its principal balance is reduced to zero.

Beginning on the subordination depletion date, the priorities stated above will cease to be in effect, and the principal allocation for the senior target-rate classes of each group will be allocated to the senior target-rate classes of the group in proportion to their principal balances on the preceding day.

15.2 NAS classes

Classes ▇▇-▇, ▇▇-▇▇ and IA-12 are non-accelerated senior, or NAS classes.

For the first 60 distribution days, the principal allocation for a NAS class will be zero. For distribution day 61 and after, the principal allocation for each NAS class will equal

· its proportionate share, based on the principal balances of the group’s target-rate classes, of scheduled principal payments on the related pool’s target-rate strip allocated to the group’s target-rate classes for that distribution day, plus

· the following percentage of its proportionate share, based on principal balances of the group‘s target-rate classes, of unscheduled principal payments on the related pool’s target-rate strip allocated to

the group’s target-rate classes for that distribution day:

distribution day	percentage
0 - 60	0%
61 - 72	30%
73 - 84	40%
85 - 96	60%
97 - 108	80%
109 and after	100%

15.3 PAC and TAC classes

Classes IA-2 through IA-4, and IA-8 through IA-10, are planned amortization (or PAC) classes. The aggregate planned balances for the PAC classes are given in the PAC Schedule.

There are no targeted amortization (or TAC) classes.

16	Distributions

16.1 Types of distributions

Each distribution will be either an interest distribution, a principal distribution, a reimbursement, or a residual distribution, as described in “- Distribution priorities” below.

16.2 Accrual and accrual directed classes

Class IA-6 is an accrual class. Its accrual directed class is class IA-5.

On each distribution day before its accrual termination day, the interest distribution for class IA-6 will be redirected to class IA-5 until its principal balance is reduced to zero.

If on a distribution day before an accrual class’s accrual termination day, the accrual class’s interest distribution exceeds the aggregate principal balances of its accrual directed classes, then

· only that portion of the accrual class’s interest distribution that equals the aggregate principal balances of its accrual directed classes will be redirected to the accrual directed classes, and

· the excess will be distributed as principal to the accrual class itself.

If interest distributions on multiple accrual classes are directed to the same accrual directed classes, then on the last distribution day before those accrual classes’ accrual termination day, the redirected portion of the interest distribution for each such accrual class will be in proportion to the principal balances of such accrual classes on the day before the distribution day.

16.3 Distribution priorities

Subject to section 18, “loss recoveries,” on each distribution day, the pool distribution amount will be first distributed to any Insurer to pay any insurance premium, and then to the outstanding classes in the following priority (and, if there are any insured classes, the insured payment and amounts withdrawn from the reserve fund will be applied to make payments to the insured class certificates as provided in “Insured classes” below):

(1) To each senior class, first, its current interest allocation for that distribution day, and second its interest allocation carryforward from the preceding distribution day, except that an accrual class’s interest distributions may be redirected as described in “- Accrual and accrual directed classes” above. Distributions of current allocations among the senior classes will be in proportion to current interest allocations for, and distributions of interest allocation carryforwards will be in proportion to interest allocation carryforwards to, that distribution day.

(2) (a) To any ratio-stripped PO class, principal up to its principal allocation for that distribution day, and (b) to the senior

target-rate classes, principal up to their aggregate principal allocation for that distribution day, to be distributed to the senior target-rate classes in the priorities described in “Allocations among the senior classes - Order of allocation among senior target-rate classes” above.

(3) To each subordinated class, in order of seniority, first, interest up to its interest allocation for that distribution day, and second, principal up to its principal allocation for that distribution day, except that a subordinated class’s principal distribution may be used to reimburse a ratio-stripped PO class, as described in the following paragraph.

(4) Principal distributed to the subordinated classes under the preceding paragraph will be used to reimburse a ratio-stripped PO class up to the amount of (a) any realized subordinated losses previously allocated to the ratio-stripped PO class, and (b) any reduction to the ratio-stripped PO class’s principal balance to reflect the excess of (i) the aggregate principal allocations to the ratio-stripped PO class over (ii) the aggregate principal distributions to the ratio-stripped classes, as described in “Adjustments to class balances” below, to the extent that such losses and reductions were not previously reimbursed under this paragraph (4) or “Loss recoveries” below. Such reimbursements will be taken from distributions to the subordinated classes in order of subordination.

(5) To each class, in order of seniority, a reimbursement of any reduction to the classes’ principal balances to reflect the excess of (a) the aggregate principal allocations to the classes over (b) the aggregate principal distributions to the classes, as described in “Adjustments to class balances” below, to the extent such reductions were not previously reimbursed. Classes with equal seniority will share in the reimbursement in proportion to such unreimbursed reductions.

(6) To the residual certificates, a residual distribution of the remaining pool distribution amount.

A class that is no longer outstanding cannot receive a distribution.

Notwithstanding anything to the contrary in this agreement, no distribution will be made to a subordinated class on a distribution day if on that distribution day the principal balance of a more senior class would be reduced by any part of the principal portion of a realized subordinated loss.

16.4 Distributions to certificate holders

On each distribution day, distributions to a class will be distributed to the holders of the certificates of the class in proportion to the principal or notional balances of their certificates.

16.5 Final distribution on the residual certificates

Upon termination of the Trust in accordance with section 9.1, “Termination upon repurchase by CMSI or liquidation of all mortgage loans,” any class PR certificates, and if there are no class PR certificates, the LR certificates will receive all amounts remaining in the certificate account and in any retail reserve fund after all required distributions on the certificates, and any required distributions to any Insurer, have been made.

16.6 Wire transfer eligibility

The minimum number of single certificates eligible for wire transfer on each distribution day, for the certificates, is 1,000 (representing a $1,000,000 initial principal balance or initial notional balance) and, for

the residual certificates, a 100% percentage interest.

17	Adjustments to class balances

On each distribution day, the principal balance of each class that is not an IO class will be adjusted, in the following order, as follows:

(1) The principal balance of any ratio-stripped PO class will be reduced by realized losses on its PO strip for the preceding month.

(2) The aggregate principal balance of the target-rate classes will be reduced by the principal portion of realized non-subordinated losses on the target-rate strip for the preceding month. The reduction will first be allocated between the subordinated classes, collectively, and the senior target-rate classes, collectively, in proportion to aggregate principal balances. The reduction for the subordinated classes will be allocated to the individual subordinated classes in proportion to their principal balances. The reduction for the senior target-rate classes will be allocated to the individual senior target-rate classes in proportion to their principal balances, except that the principal balance of an accrual class will be deemed to be the lesser of its principal balance or its initial principal balance.

(3) To the extent that on the distribution day an interest distribution to an accrual class is redirected to an accrual directed class, the principal balance of the accrual class will be increased.

(4) The principal balance of each class will be reduced by its principal distributions for that distribution day, including

(a) principal distributions to an accrual directed class that are redirected from interest distributions to an accrual class, and

(b) principal distributions to a subordinated class, even if part or all of those principal distributions are, pursuant to section 16.3(4), used to reimburse a ratio-stripped PO class.

However, any portion of an accrual class’s interest distribution that, on the distribution day before the class’s accrual termination day, is distributed as principal to the accrual class itself, will neither increase nor decrease the class’s principal balance.

(5) The aggregate principal balance of the target-rate classes will be reduced by the principal portion of realized subordinated losses on the target-rate strip for the preceding month. The reductions will be applied first to the subordinated classes in order of subordination, in each case until the principal balance of the class is reduced to zero. If the realized subordinated losses exceed the principal balance of the subordinated classes, the principal balance of the senior target-rate classes will be reduced by the amount of the excess. The excess will be allocated among the senior target-rate classes in proportion to their principal balances, except that for this allocation, the principal balance of an accrual class will be deemed to be the lesser of its principal balance or its initial principal balance.

(6) The principal balance of any ratio-stripped PO class will be reduced by the excess of (a) the class’s principal allocation over (b) the class’s principal distribution for that distribution day.

(7) The principal balance of each target-rate class will be reduced, in order of subordination, in an aggregate amount equal to the excess of (a) the aggregate principal allocations to the target-rate classes over (b) the aggregate principal

distributions to the target-rate classes. Classes of equal seniority will share in such reduction in proportion to the amounts by which the principal allocation to each such class exceeded its principal distribution.

For purposes of the preceding paragraphs (1) through (7),

· the principal portion of a debt service reduction will not be considered a realized loss, and

· references to the class principal balances in any paragraph mean the principal balances after the adjustments required by the preceding numbered paragraphs.

Where the principal balance of a class is reduced due to a realized loss under the preceding paragraphs (1), (2) or (5), the loss will be said to be allocated to the class (an allocated loss) to the extent of the reduction.

18	Loss recoveries

The following rules for loss recoveries supersede any conflicting rules in “Distributions” or “Adjustments to class balances” above.

On each distribution day, the amount of any loss recovery for the preceding month will be distributed as follows:

First, to each senior class to the extent of and in proportion to its aggregate realized losses for that and all preceding months that were not previously reimbursed under this paragraph or, for a ratio-stripped PO class, paragraph 4 of “Distributions — Distribution priorities” above.

Second, to the target-rate classes in the same manner as a distribution of unscheduled principal.

Distributions made pursuant to paragraph First above will not result in any adjustments to class balances, but distributions made pursuant to paragraph Second above will result in the normal adjustments to the class balances described in paragraph 4 of “Adjustments to class balances” above.

The principal balances of the subordinated classes will be increased in order of seniority to the extent of their aggregate realized losses for that and all preceding months that were not previously reimbursed under this paragraph, up to an aggregate amount for all subordinated classes equal to the loss recovery less the amounts distributed to the senior classes under paragraph First above.

Example: In May, there is a $1,000 of loss recovery. On the June distribution day, prior to any distributions or adjustments, the senior classes have aggregate unreimbursed losses of $100 and the subordinated classes have aggregate unreimbursed losses of $700. Then on the June distribution day,

1 $100 of the loss recovery will be distributed to the senior classes to reimburse them for previously allocated losses, but the distribution will not reduce the principal balances of the senior classes.

2 The remaining $900 of the loss recovery will be distributed to the target-rate classes in the same manner as unscheduled principal, and class balances will be reduced by the amount of the distributions.

3 The principal balances of the subordinated classes will be increased by the remaining $900. (The increase may be less than $900 if any of the subordinated classes are no longer outstanding.)

If expenses on the liquidated loans for any month exceed the amounts recovered on the liquidated loans for the month, the excess will be treated as a realized loss on the mortgage loans.

19	Additional structuring features

The preceding provisions for allocations and distributions, and for adjustments to class balances, are subject to the following

sections on LIBOR classes, composite and component classes, multiple-pool series, retail classes, and insured classes.

20	LIBOR classes

Classes IA-5 and IA-7 are LIBOR classes.

Each LIBOR class will have a monthly LIBOR accrual period from the day of the month indicated in the footnotes to the table in “The Series - General terms for classes” above through the day preceding the first day of the next LIBOR accrual period. The first LIBOR accrual period for a class will be the latest possible LIBOR accrual period that ends before the first distribution day.

Example: The LIBOR accrual period for a LIBOR class begins on the 25th day of the month, and the first distribution day is February 25, 200x. Then the first LIBOR accrual period for the class begins on January 25, 200x and runs through February 24, 200x, the second LIBOR accrual period begins on February 25, 200x and runs through March 24, 200x, and so forth.

A LIBOR class will not accrue interest for any period before its first LIBOR accrual period. The interest rate for each LIBOR class is stated in “The series - General terms for classes” above.

CitiMortgage will determine LIBOR for each LIBOR accrual period (after the first LIBOR accrual period) on the second business day before the beginning of each LIBOR accrual period as follows:

· LIBOR for any determination day will be the British Bankers Association LIBOR rate for US dollar deposits with a one-month maturity at 11AM, London time on that day, as such rate appears on Telerate Page 3750, Bloomberg Page BBAM, or another page of these or any other financial reporting service in general use in the financial services industry, rounded upward, if necessary, to the nearest multiple of 1/16 of 1%.

· If no rate is so reported on that day, CitiMortgage will determine LIBOR on the basis of the rates on that day at approximately 11AM, London time, at which deposits in U.S. Dollars with a maturity of one month in a principal amount of not less than U.S. $1 million and representative for a single transaction in that market at that time, are offered to prime banks in the London interbank market for at least four major banks in the London interbank market selected by CitiMortgage. CitiMortgage will request the principal London office of each such bank to provide a quotation of its rate. If at least two such quotations are provided, LIBOR will be the arithmetic mean of those quotations.

· If fewer than two quotations are provided, LIBOR will be the arithmetic mean of the rates quoted at approximately 11AM, New York time, on that day by three major banks in New York City selected by CitiMortgage for loans in U.S. Dollars to leading European banks having a maturity of one month in a principal amount of not less than U.S. $1 million that is representative for a single transaction in such market at such time. If the banks selected by CitiMortgage are not quoting such rates, LIBOR will be LIBOR for the preceding LIBOR accrual period.

CitiMortgage may designate an affiliate or a third party to determine LIBOR.

21	Composite and component classes

The composite classes of the series, and each composite class’s component classes are shown in the table in “The series - General terms for classes” above.

Each composite class is comprised of two or more component classes. Certificates are only issued for composite classes. Component classes cannot be severed from their composite classes, and cannot be separately transferred. Component classes are, however, considered classes for all purposes of the preceding sections on allocations and distributions except that all distributions to the component classes of a composite class will become distributions to the composite class. A composite class is not considered a class for purposes of allocations and distributions, but instead receives all the distributions made to any of its component classes. Voting is by composite, not component, classes.

In a multiple-pool series, each subordinated class is a composite class formed of two or more component classes. Unless otherwise specified, references to a “subordinated class” mean the composite class.

22	Multiple-pool series

This is a multiple-pool series. The mortgage loans of this series are divided into two pools. Pool I consists of the mortgage loans described in exhibit B-1, and Pool II consists of the mortgage loans described in exhibit B-2.

Each class of this series (other than certain composite classes) belongs to a group of classes related to a specific pool. The designation of each class in a group bears the roman numeral prefix of its related pool, and the group is referred to by that prefix.

Example: Classes related to pool I bear the prefix “I,” as ▇▇-▇, ▇▇-▇, etc., and are referred to collectively as “group I.”

With exceptions described below, the classes of each group are treated like a separate series, with allocations to the classes of the group being based solely on payments on the related pool. Any ratio-stripping will be done on a pool basis, so that there will be separate PO, IO and target-rate strips for each pool, with the related group having its own target-rate, and ratio-stripped IO and PO, classes.

The subordinated classes of each group will be component classes. A ratio-stripped IO or PO class of a group will only be a component class if so designated in “The series - General terms for classes” above.

22.1 Adjustment of subordinated component class principal balances

On each distribution day, the aggregate amount of any

· realized subordinated losses on the mortgage loans in a pool, or

· excess of the aggregate principal allocations to the related group’s target-rate classes over the aggregate principal distributions to those classes,

that, in accordance with “Adjustments to class balances” above, would reduce the principal balances of the group’s subordinated component classes in order of subordination if the pool and the related groups were considered a separate series, will instead reduce

· the principal balances of the subordinated composite classes in order of subordination, and

· the aggregate principal balance of the group’s subordinated component classes,

by that amount.

Such reduction in the aggregate principal balance of a group’s subordinated component classes will result in adjustments to the principal balance of the subordinated component classes of each group so the ratio of the principal balances of the component classes from each group will be the same for each subordinated composite class.

Example: Assume subordinated composite classes B-1 through B-6, each with a principal balance of $1,000. There are two groups, I and II, and the aggregate principal balance of each group’s subordinated component classes is $3,000. Then for each subordinated composite class, the ratio of the principal balance of its group I component class to the principal balance of its group II component class must be 1 to 1. Consequently, both the group I and the group II component class of each subordinated composite class will have a principal balance of $500.

Now assume a $750 subordinated loss in pool I. Then

· the principal balance of class B-6 will be reduced by $750, to $250, which will reduce the aggregate principal balance of the subordinated composite classes to $5,250,

· the aggregate principal balance of the group I subordinated component classes will be reduced by $750, to $2,250, while the aggregate principal balance of the group II subordinated component classes will remain at $3,000;

· the ratio of the aggregate principal balance of the group I subordinated component classes to the aggregate principal balance of the group II subordinated component classes will be $2,250 to $3,000, or 3 to 4;

· for classes B-1 through B-5, the principal balance of the composite class will remain at $1,000, but the principal balance of its group I component class will be approximately $428.57, and the principal balance of its group II component class will be approximately $571.43 (a ratio of 3 to 4); and

· class B-6’s principal balance of $250 will be comprised of a group I component class with a principal balance of approximately $107.14, and a group II component class with a principal balance of approximately $142.86 (a ratio of 3 to 4).

If subordinated losses on a mortgage pool for a distribution day exceed the aggregate principal balance of the subordinated component classes of the related group, the aggregate principal balance of such component classes will be reduced to zero, and the aggregate principal balance of the subordinated component classes of the other groups will be reduced by the excess.

Example: Suppose that in the series in the preceding example, the group I subordinated component classes and the group II subordinated component classes each have an aggregate initial principal balance of $3,000, and that each subordinated composite class, B-1 through B-6 has a principal balance of $1,000. Now suppose that there are $4,000 of subordinated losses on the mortgage loans in pool II’s target-rate strip, but no losses on the mortgage loans in pool I’s target-rate strip. Then the entire $4,000 of losses will be allocated to the subordinated classes, reducing the principal balance of classes B-3 through B-6 to zero. Classes B-1 and B-2 will each retain a principal balance of $1,000, comprised of a group I component class with a principal balance of $1,000 and a group II component class with a principal balance of $0. The principal balance of the subordinated group I component classes will thus be reduced by $1,000 even though there are no losses on the pool I target-rate strip.

Subject to “- Undercollateralization” below, if realized subordinated losses on a distribution day exceed the aggregate principal balance of the subordinated classes, the aggregate principal balance of the senior classes in each group will be reduced by the group’s proportional share of the excess losses, based on the proportions of all the losses for that distribution day in the mortgage loan pools.

Example: Assume that for a distribution day, there are $2,250 of realized subordinated losses in pool I and $4,500 of realized subordinated

losses in pool II. The aggregate principal balance of the subordinated classes is only $6,000. Then the principal balance of the subordinated classes will be reduced to $0, and the remaining $750 of losses will reduce the aggregate principal balance of the senior classes of group I by $250 (or 1/3 of $750), and will reduce the aggregate principal balance of the senior classes of group II by $500 (or 2/3 of $750). The principal balances of the component classes of the subordinated classes are irrelevant for these purposes.

22.2 Maintenance of subordination

Impairment of subordination for subordinated classes of a multiple-pool series will be determined based on composite, not component, classes. In determining whether a composite class has an impaired subordination level, the principal balance of the composite class will equal the sum of the principal balances of its component classes. If a subordinated composite class has an impaired subordination level, then principal will be allocated among the subordinated composite classes pursuant to “Allocations - Maintenance of subordination” above, and, for purposes of adjusting principal balances, will be further allocated to the component classes in proportion to their principal balances.

22.3 Distribution shortfalls

If on a distribution day, payments on the mortgage loans in the target-rate strip for a pool are not sufficient to permit payments of any insurance premium due to an Insurer, and all interest and principal allocated to the senior target-rate classes of the related group, then the pool may receive insurance premium, interest and principal distributions from payments on the mortgage loans in another pool once any insurance premium due is paid to the Insurer, and full interest and principal distributions are made to the senior target-rate classes of the group related to the other pool.

Example: Suppose that there are two groups of classes and that on a distribution day, cash available for distribution to the group I senior-target rate classes from payments on the pool I mortgage loans is $1,000 less than the aggregate interest and principal allocations to group I’s senior target-rate classes, while cash available for distribution to the group II senior-target rate classes from payments on the pool II mortgage loans exceeds the aggregate interest and principal allocations to group II’s senior target-rate classes by $1,500. Then $1,000 of the extra $1,500 available to group II will be used to make full interest and principal distributions to the group I senior target-rate classes, and only the remaining $500 will be distributed to the group II subordinated component classes.

If there are several pools for which mortgage loan payments do not provide enough cash for full distributions to the senior target-rate classes and any Insurer, the related groups will receive cash from other pools in proportion to the aggregate amount by which any insurance premium due to an Insurer, and interest and principal distributions would otherwise fall short of interest and principal allocations. If there are several pools where mortgage loan payments provide cash in excess of the amount required for full distributions, they will provide cash to the senior target-rate classes, and any Insurer, of those groups related to the other pools in proportion to the amounts of the excess.

22.4 Undersubordination

If on a distribution day before the subordination depletion date, the principal balances of all the senior target-rate classes of any group (but not the principal balances of all the group’s subordinated component

classes) have been reduced to zero, and there is undersubordination (as defined below), then on that distribution day, before any distributions are made,

· the pool distribution amount of the group will be reduced by an amount (the reduction amount) equal to the lesser of (1) unscheduled principal payments on the related pool’s target-rate strip received by the Trust during the preceding month and (2) the excess, determined without regard to this section “- Undersubordination,” of the pool distribution amount over the amount required to be used to reimburse any ratio-stripped PO classes,

· the principal allocation to each class in the group will be reduced by the class’s proportionate share, based on principal balances, of the reduction amount,

· the pool distribution amount of each group whose senior target-rate classes have not been reduced to zero will be increased by a proportionate share of the reduction amount based on the aggregate principal balance of the senior target-rate classes of each such group, and

· the aggregate principal allocation for the senior target-rate classes of each group whose senior target-rate classes have not been reduced to zero will be increased by the portion of the reduction amount added to its pool distribution amount, which increased aggregate allocation will be further allocated among the senior target-rate classes in accordance with the rules in “Allocations among the senior target-rate classes” above.

There is undersubordination on a distribution day if either

· the subordination level of the senior classes (without regard to group) on that distribution day is less than 200% of the initial subordination level of the senior classes, or

· the aggregate scheduled principal balance of the mortgage loans in any pool that are delinquent 60 days or more (including for this purpose mortgage loans in foreclosure and real estate owned by the Trust as a result of Mortgagor default), averaged over the last six months, is 50% or more of the principal balance of the related group’s subordinated component classes.

22.5 Undercollateralization

Because losses on a mortgage loan may be allocated in part to the subordinated component classes of a different group, the scheduled principal balance of a pool’s target-rate strip could differ from the aggregate principal balance of the related group’s target-rate classes. If the scheduled principal balance of a pool’s target-rate strip is less than the aggregate principal balance of the related group’s target-rate classes, the group will be undercollateralized by the amount of the difference; conversely, if the scheduled principal balance of a pool’s target-rate strip is more than the aggregate principal balance of the related group’s target-rate classes, the group will be overcollateralized by the amount of the difference.

If a group is undercollateralized, the normal distribution rules will be adjusted as follows:

(1) To the extent that scheduled interest payments on the target-rate strip of a pool related to an overcollateralized group exceed the aggregate interest allocations to that groups’ target-rate classes, plus any insurance premium due to an Insurer, that excess, up to the amount of any interest allocation carryforwards that the undercollateralized group would otherwise experience on that distribution day and the insurance premium, will be deducted from the pool distribution amount for the overcollateralized group and added to the

pool distribution amounts for the undercollateralized group. If there is more than one such undercollateralized group, or more than one overcollateralized group, then (a) amounts will be deducted from the pool distribution amounts for the groups that are overcollateralized in proportion to such excess interest payments, up to the aggregate amount of such interest allocation carryforwards and the insurance premium for the undercollateralized groups, and (b) amounts will be added to the pool distribution amounts of the undercollateralized groups in proportion to the amount of such interest allocation carryforwards and insurance premium.

(2) Before the subordination depletion date, if one or more groups is undercollateralized and the principal balance of each of the groups’ subordinated component classes has been reduced to zero, then (a) all amounts that (after required reimbursements to any ratio-stripped PO classes) would otherwise be distributed as principal to the subordinated component classes of the other groups, up to the aggregate amount by which such undercollateralized groups are undercollateralized, will, in proportion to the aggregate principal balance of the subordinated component classes of such other groups, be deducted from the pool distribution amount and the principal allocations to the subordinated component classes of such other groups, and (b) such amount will be added to the pool distribution amounts and the principal allocations of the target-rate classes of such undercollateralized groups, in proportion to the amount by which such groups are undercollateralized.

(3) After the subordination depletion date, if a group is undercollateralized, then

· once a group’s target-rate classes are all reduced to zero, principal payments on the related pool’s target-rate strip will be added to the pool distribution amount and to the principal allocations of the target-rate classes of the undercollateralized groups, in proportion to the amount by which they are undercollateralized, and

· realized losses on the target-rate strips of the pools related to the overcollateralized groups will, up to the amount by which the group is overcollateralized, not reduce the principal balances of the target-rate classes of those groups, but will instead reduce the principal balances of the target-rate classes of the undercollateralized groups, in proportion to the amount by which they are undercollateralized, and in accordance with “Adjustments to class balances” above. If there is more than one overcollateralized group, the losses that will not reduce principal balance will be in proportion to the amount by which each group is overcollateralized. If there is more than one undercollateralized group, the aggregate reductions in principal balances for each group will be in proportion to the amounts by which such groups are undercollateralized.

22.6 Non-subordinated interest shortfalls

Prior to the subordination depletion date, reductions to interest allocations due to (a) interest shortfalls due to the federal Servicemembers Civil Relief Act or any comparable state laws and (b) non-supported prepayment interest shortfalls will be allocated pro-rata to all the classes of all the groups, regardless of the pools in which the shortfalls originate.

From and after the subordination depletion date,

· interest shortfalls due to the federal Servicemembers Civil Relief Act or any

comparable state laws will be separately calculated for each pool, and will be allocated solely to the classes of the related group, and

· the compensating cap and non-supported prepayment interest shortfalls will be separately calculated for each pool, and non-supported prepayment interest shortfalls for a pool will be allocated solely to the classes of the related group.

23	Super senior classes

The following table lists the super senior classes, and their respective super senior support classes.

Super senior class	Super senior support class	Support amount
IA-1	IA-11	$1,109,064.00
IA-1	IA-12	$473,407.59
▇▇-▇	▇▇-▇▇	$1,933,807.41
▇▇-▇	▇▇-▇▇	$2,887,008.00

After the subordination depletion date, any loss (other than a non-subordinated loss) on a target-rate strip that would otherwise reduce the principal balance of a super senior class will instead reduce the principal balance of its super senior support classes.

A loss that would otherwise reduce the principal balance of super senior class IA-1 will instead reduce the principal balances of super senior support classes IA-11 and IA-12 in proportion to their principal balances; once class IA-12 has been reduced by such losses by the support amount shown above, all further losses that would otherwise reduce the principal balance of class IA-1 will instead reduce the principal balance solely of class IA-11, until the principal balance of class IA-11 is reduced to zero .

For these purposes, the principal balance of a super senior support class on a distribution day will be determined after giving effect to the adjustments described in paragraphs (2) through (5) of section 17, “Adjustments to class balances,“ for that distribution day (which include the reductions for non-subordinated losses, principal distributions and realized subordinated losses), but before the adjustments required by this section 23.

24	Retail classes

There are no retail classes. There is no retail reserve fund.

25	Insured classes

There are no insured classes. There is no Insurer, certificate insurance policy, insurance premium, or reserve fund.

26	Advance account

There is/are no advance account, advance account advances, advance account available advance amount, advance account depository, advance account depository agreement, advance account funding date, or advance account trigger date, Paying Agent failure, or Paying Agent failure advance.

27	REMIC provisions

27.1 Constituent REMICs

(a) CMSI and the Trustee will make the appropriate elections to treat the Trust Fund, and the affairs of the Trust Fund will be conducted so as to qualify the Trust Fund, for federal income tax purposes as three separate constituent REMICs - the pooling REMIC, the lower-tier REMIC, and the upper-tier REMIC. The pooling REMIC will be the applicable constituent REMIC for purposes of section 3.21.

The assets of the pooling REMIC will consist of the mortgage loans, such amounts

as may from time to time be held in the certificate account, any insurance policies relating to a mortgage loan, and property that secured a mortgage loan and that has been acquired by foreclosure or deed in lieu of foreclosure and all proceeds thereof. Classes IA-PO, IA-IO, IIA-PO, IIA-IO, and the class P regular interests described below, are designated as the regular interests in the pooling REMIC within the meaning of Internal Revenue Code Section 860G(a)(1). Class PR is designated as the residual interest in the pooling REMIC within the meaning of Internal Revenue Code Section 860G(a)(2).

The assets of the lower-tier REMIC will consist of the class P regular interests described below, the Trustee’s rights under any certificate insurance policy and reserve fund, any retail reserve fund, and any assets in the lower-tier REMIC account described below. Classes IA-1 through ▇▇-▇, ▇▇-▇, ▇▇-▇ through IA-12, IIA-1, and B-1 through B-6, and any class L regular interests described below, are designated as the regular interests in the lower-tier REMIC. Class LR is designated as the residual interest in the lower-tier REMIC.

The assets of the upper-tier REMIC will consist of any class L regular interests described below, and any assets in the upper-tier REMIC account described below. Classes IA-5, and IA-7 are designated as the regular interests in the upper-tier REMIC. Class R is designated as the residual interest in the upper-tier REMIC.

27.2 The class P and class L regular interests

There are four uncertificated class P regular interests, each designated as “CMALT (CitiMortgage Alternative Loan Trust), Series 2006-A4 REMIC Pass-Through Certificates,” and further individually designated as a

· “PI-M regular interest,”

· “PI-Q regular interest,”

· “PII-M regular interest,” and

· “PII-Q regular interest.”

There is one uncertificated class L regular interest, designated as “CMALT (CitiMortgage Alternative Loan Trust), Series 2006-A4 REMIC Pass-Through Certificates,” and further designated as the “LI-5 regular interest.”

The initial principal or notional balances and certificate rates of the class P and class L regular interests are:

Regular interest	initial principal (or notional) balance	certificate rate (per annum)
PI-M	$1,320.295275	6%
PI-Q	$303,321,536.454725	6%
PII-M	$45.620977	5.75%
PII-Q	$10,466,416.149023	5.75%
LI-5	$104,146,650.00	6%

The Trustee acknowledges that it is holding the class P regular interests as assets of the lower-tier REMIC and any class L regular interests as assets of the upper-tier REMIC.

27.3 Distributions to class P and class L regular interests

On each distribution day, each regular interest will receive a principal distribution, or allocation of the principal portion of realized losses, equal in the aggregate to the principal distribution, or allocation of the principal portion of realized losses, for that day on,

· for the PI-M and PI-Q regular interests, the pool I target-rate strip;

· for the PII-M and PII-Q regular interests, the pool II target-rate strip, and

· for the class LI-5 regular interest, class IA-5.

Recoveries of previously allocated realized losses of principal will be allocated to the class P and any class L regular

interests in the same manner as realized losses were allocated to them.

For each distribution day, and for each pool x and y, the Px-M regular interest will receive distributions of principal, or allocation of the principal portion of realized losses on the related target-rate strip, so as to keep its principal balance (computed to $.000001) equal to 0.01% of the aggregate principal balance of the subordinated component classes of the related group. However, if the ratio of the principal balance of the Px-M regular interest to the principal balance of the Py-M regular interest is not the same as the ratio of the aggregate principal balance of the component classes xB-1 through xB-6 to the aggregate principal balance of the component classes yB-1 through yB-6, then the least amount of principal will be distributed to the Px-M or Py-M regular interest, as applicable, so that the ratio of the principal balance of the Px-M regular interest to the principal balance of the Py-M regular interest will be the same as the ratio of the aggregate principal balance of the component classes xB-1 through xB-6 to the aggregate principal balance of the component classes yB-1 through yB-6. Also, for such distribution day, the Px-Q regular interest will receive the balance of the principal distribution, and allocation of the principal portion of realized losses on its related target-rate strip.

As of any date, the principal balance of the class LI-5 regular interest will equal the principal balance of class IA-5.

On each distribution day, each class P and any class L regular interest will receive an interest distribution at its certificate rate, and interest shortfalls and the interest portion of realized losses for the related target-rate strip will be allocated to such regular interest in the same proportion as interest is allocated to them, provided that

· (a) prior to the subordination depletion date, non-supported prepayment interest shortfalls will be allocated pro-rata to all the class P regular interests, regardless of the pool in which the shortfalls originate, and (b) from and after the subordination depletion date, non-supported prepayment interest shortfalls for any pool x (where x is a variable for pool designations I, II, etc.) will be allocated solely to the Px-M and Px-Q regular interests, and

· (a) prior to the subordination depletion date, any class L regular interest will be allocated its proportional share, based on accrued interest of any lower-tier REMIC regular interests, of non-supported prepayment interest shortfalls, regardless of the pool in which the shortfalls originate, and (b) from and after the subordination depletion date, any class L regular interest will be allocated its proportional share, based on accrued interest of any class L regular interests and the other lower-tier REMIC regular interests designated class xA, of non-supported prepayment interest shortfalls for pool x.

No interest shortfall amount or unpaid interest shortfall on any class P or class L regular interest will bear interest.

The certificate rate for the class LI-5 regular interest is comprised of the sum of LIBOR plus 0.65% per annum payable on the class IA-5 certificates, and 5.35% per annum minus LIBOR payable on the notional balance of the class IA-7 certificates.

27.4 REMIC accounts and distributions

CitiMortgage, the Trustee and the Paying Agent will

· perform their duties in a manner consistent with the REMIC provisions of the Internal Revenue Code, and will not

knowingly take or fail to take any action that would adversely affect the continuing treatment of the Trust Fund as segregated asset pools and the treatment of each such segregated asset pool as a REMIC or would result in the imposition of a tax on the Trust Fund, or any constituent REMIC, and

· carry out their covenants in this agreement and the elections and reporting required in section 3.15 on behalf of each constituent REMIC, including maintaining the following segregated accounts:

· the certificate account,

· if there is a pooling REMIC, a pooling REMIC account,

· a lower-tier REMIC account, and

· if there is an upper-tier REMIC, an upper-tier REMIC account.

Any pooling REMIC account, the lower-tier REMIC account, and any upper-tier REMIC account will be established in the same manner as the certificate account.

CitiMortgage, on behalf of the Trustee, will deposit daily in the certificate account in accordance with section 3.3 all remittances received by it, any amounts required to be deposited in the certificate account pursuant to section 3.2, all other deposits required to be made to the certificate account other than those amounts specifically designated to be deposited in any pooling REMIC account, the lower-tier REMIC account, or any upper-tier REMIC account in this section, “REMIC accounts and distributions,” and all investments made with moneys on deposit in the certificate account, including all income or gain from such investments, if any. Funds on deposit in the certificate account will be held and invested in accordance with the applicable provisions of section 3.2 and 3.20. Distributions from the certificate account will be made in accordance with sections 3.6, 3.8 and these Series Terms to make payments in respect of the regular and residual interests in any pooling REMIC, the lower-tier REMIC, and any upper-tier REMIC and to pay servicing fees in accordance with section 3.6(h) and any insurance premium.

Notwithstanding anything herein to the contrary, regular and residual interests in any pooling REMIC, the lower-tier REMIC, and any upper-tier REMIC will not receive distributions directly from the certificate account. On each distribution day,

· if there is a pooling REMIC, CitiMortgage, on behalf of the Trustee, will withdraw from the certificate account and deposit by 12 noon in the pooling REMIC account all distributions to be made on such distribution day in respect of interest on or in reduction of the principal balance of any class P regular interests, and

· if there is no pooling REMIC, CitiMortgage, on behalf of the Trustee, will withdraw from the certificate account and deposit by 12 noon in the lower-tier REMIC account all distributions to be made on such distribution day in respect of interest on or in reduction of the principal balance of the regular interests in the lower-tier REMIC.

If there is an upper-tier REMIC, CitiMortgage, on behalf of the Trustee, will immediately thereafter withdraw from the lower-tier REMIC account and deposit in the upper-tier REMIC account all distributions to be made on such distribution day in respect of interest on or in reduction of the principal balance of any class L regular interests.

The Trustee will cause to be distributed from the lower-tier REMIC account and any upper-tier REMIC account, to the extent funds are on deposit therefor, all amounts required to be distributed with respect to the regular and residual interests in the

lower-tier REMIC and any upper-tier REMIC as specified in these Series Terms.

To the extent that any part of the lower-tier REMIC account or any upper-tier REMIC account is designated in these Series Terms as an investment account, the provisions in section 3.19 applicable to the investment of funds will apply to such REMIC accounts. In addition, section 3.3(a) regarding commingling will apply to such REMIC accounts.

(b) CitiMortgage will maintain books for constituent REMICs on a calendar year taxable year and on the accrual method of accounting.

(c) The Trustee will not create, or permit the creation of, any “interests” in any constituent REMIC within the meaning of Internal Revenue Code Section 860D(a)(2) other than the interests represented by the certificates or, if there are multiple REMICs, the uncertificated regular interests in any pooling REMIC or (if there is an upper-tier REMIC) the lower-tier REMIC.

(d) Except as otherwise provided in the Internal Revenue Code, CitiMortgage will not grant, and neither CitiMortgage nor the Trustee will accept, property unless (i) substantially all of the property held by each constituent REMIC constitutes either “qualified mortgages” or “permitted investments” as defined in Internal Revenue Code Sections 860G(a)(3) and (5), respectively, and (ii) no property will be granted to a constituent REMIC after the startup day, unless the grant would not subject the constituent REMIC to the 100% tax on contributions to a REMIC after the startup day imposed by Internal Revenue Code Section 860G(d).

(e) The Trustee will not accept on behalf of the Trust Fund or a constituent REMIC any fee or other compensation for services and will not accept on behalf of the Trust Fund any income from assets other than those permitted to be held by a REMIC.

(f) Neither CitiMortgage nor the Trustee will sell or permit the sale of all or any portion of the mortgage loans, or of an Eligible Investment held in the certificate account or in any REMIC account (other than in accordance with sections 2.2, 2.3, 2.4 and 3.19(a)) unless such sale is pursuant to a “qualified liquidation” as defined in Internal Revenue Code Section 860F(a)(4)(A) and is in accordance with section 9.1.

27.5 Tax matters person

If in any taxable year there will be more than one holder of any class of residual certificates, a tax matters person may be designated for the related REMIC, who will have the same duties for the related REMIC as those of a “tax matters partner” under Subchapter C of Chapter 63 of Subtitle F of the Internal Revenue Code, and who will be, in order of priority, (i) CitiMortgage or an affiliate of CitiMortgage, if CitiMortgage or such affiliate is the holder of a residual certificate of the related REMIC at any time during the taxable year or at the time the designation is made, (ii) if CitiMortgage is not a holder of a residual certificate of the related REMIC at the relevant time, CitiMortgage as agent for the holder of the residual certificate of the related REMIC, if the designation is permitted to be made under the Internal Revenue Code, or (iii) the holder of a residual certificate of the related REMIC or person who may be designated a tax matters person in the same manner in which a tax matters partner may be designated under applicable Treasury Regulations, including Treas-ury Regulations § 1.860F-4(d) and tem-porary Treasury Regulations § 301.-6231-(a)-(7)-1T.

28 YIELD MAINTENANCE AGREEMENT

28.1 Agreement

The Trustee is hereby directed to enter into a yield maintenance agreement with The Bank of New York (the yield maintenance provider) in substantially the form attached as exhibit F. The yield maintenance agreement is an asset of the Trust, but not of any constituent REMIC.

Payments to the yield maintenance provider will be made by the Underwriter, and the Trustee will have no responsibility for such payments.

Under the yield maintenance agreement, the yield maintenance provider will make certain payments (yield maintenance payments) to the Paying Agent for the benefit of the holders of the class IA-5 certificates. Yield maintenance payments received by the Paying Agent will be distributed to the holders of the class IA-5 certificates in proportion to the principal balances of their certificates.

Each yield maintenance payment to be distributed to the holders of the class IA-5 certificates will be a per annum percentage equal to the excess of LIBOR for the accrual period (but not more than 8.85%) over 5.35% of an assumed principal balance for the class for the relevant distribution day set forth in the yield maintenance agreement.

The Paying Agent will pass the yield maintenance payments through to the holders of the class IA-5 certificates, but not more than will be required to pay the class IA-5 certificates an amount (the yield maintenance amount) for that distribution day equal to a per annum rate of the excess of LIBOR for the accrual period (but not more than 8.85%) over 5.35% of the actual principal balance for the class for that distribution day.

If for any distribution day, the assumed principal balance is greater than the aggregate outstanding principal balance of the class IA-5 certificates, the yield maintenance payment by the yield maintenance provider to the Paying Agent may exceed the yield maintenance amount required to be made to the holders of the class IA-5 certificates. In such case, any excess will be deposited in a yield maintenance reserve fund maintained in an account at the Paying Agent. If for any distribution day, the assumed principal balance is less than the aggregate outstanding principal balance of the class IA-5 certificates, the yield maintenance payment will be less than the yield maintenance amount for such distribution day and a shortfall will result. The amount in the yield maintenance reserve fund, if any, will be used (i) to cover any such shortfall for any distribution day, and (ii) for distribution days after the distribution day in May 2010, to pay the yield maintenance amount. Once the principal balance of the class IA-5 certificates has been reduced to zero, or the Trust has been terminated, any funds remaining in the yield maintenance reserve fund will be paid to the Underwriter.

The yield maintenance reserve fund may not be invested.

The yield maintenance reserve fund will be treated as an “outside reserve fund” under the REMIC provisions, beneficially owned by the Underwriter, who will be entitled to any reimbursement from the REMICs with respect thereto.

28.2 Tax treatment

CitiMortgage will treat the portion of the Trust that holds the right of the class IA-5 certificates to receive payments under the yield maintenance agreement as a grantor trust for federal income tax purposes.

CitiMortgage will treat the holders of the class IA-5 certificates as the beneficial owners of the right to receive payments under the yield maintenance agreement, and the Underwriter as the beneficial owner of the yield maintenance agreement and the yield maintenance reserve fund. Based on information provided annually by CitiMortgage with respect to the Class IA-5 Certificates, the Trustee will report, or will cause to be reported, annually to the holders of the class IA-5 certificates and to the IRS (as attachments to Form 1041 or other applicable form) their allocable shares of income and expense with respect to their right to receive payments under the yield maintenance agreement under the rules applicable to notional principal contracts, taking into account the portion of the original issue price of the class IA-5 certificates allocable to their right to receive payments under the yield maintenance agreement, and treating each holder of class IA-5 certificates as if it were an original holder. CitiMortgage will not vary the investment of the holders of the class IA-5 certificates to take advantage of variations in market rates of interest to improve their rates of return.

buydown mortgage loan: Any mortgage loan for which, pursuant to a buydown subsidy agreement, (i) the mortgagor pays less than the full monthly payments specified in the mortgage note for a specified period, and (ii) the difference between the payments required under the buydown subsidy agreement and the mortgage note is provided from buydown funds.

buydown subsidy agreement: The agreement relating to a buydown mortgage loan pursuant to which an Originator may apply the buydown funds to a mortgagor’s payments.

class: For certificates, any certificates designated as a class in the Series Terms, for any class L or class P regular interests, the regular interests in the constituent REMIC designated as such in “REMIC provisions” above, and for residual certificates, all residual certificates having the same class designation. A “class” will be understood not to include a residual class of certificates unless otherwise expressly stated.

class percentage: For one or more classes, the ratio of the aggregate of the principal

balances of the classes to the aggregate of the principal balances of all classes of the series, expressed as a percentage.

classes A-x through A-y: For a positive integer x and a greater integer y, each class A-z for all integers z from x through y, inclusive. Example: “classes A-3 through A-5” means each of classes ▇-▇, ▇-▇, and A-5. If a class is designated with an integer and letter pair, then such class follows the class with the same integer x and precedes the class of the next greater integer y. Example: “classes A-3 through A-5” means, if there are classes A-4A and A-4B, each of classes ▇-▇, ▇-▇, ▇-▇▇, ▇-▇▇, and A-5.

Clearing Agency Participant: A broker, dealer, bank other financial institution or other person for whom a Clearing Agency effects book-entry transfers and pledges of securities deposited with the Clearing Agency.

collected servicing fee on a mortgage loan: For any month, the excess of the interest payment received on the mortgage loan for the month (including accrued interest due but not received from liquidation or insurance proceeds for liquidated loans) over the amount of interest on the mortgage loan for the month at the pass-through rate, up to the servicing fee CitiMortgage is permitted to retain under this agreement.

debt service reduction: For a mortgage loan, a reduction in the scheduled monthly loan payment for the mortgage loan by a court of competent jurisdiction in a proceeding under the Bankruptcy Code or any similar state law, except a reduction that would constitute a deficient valuation. If the court proceeding results in an increase in the scheduled payment for a month (for example, a final balloon payment or a payment in a month after the originally scheduled maturity of the mortgage loan), the increased payment will be considered a scheduled payment and not a debt service reduction.

Example: Suppose a homeowner has a mortgage loan with an outstanding principal balance of $50,000 and an interest rate of 7%. The loan has 10 years to run. The homeowner files for bankruptcy, and the bankruptcy court (1) reduces the outstanding principal balance to $40,000, (2) reduces the interest rate to 6%, and (3) stretches the payments out to 20 years. Then

· the $10,000 reduction in principal owed is a bankruptcy loss, and

· the difference between the monthly payment the homeowner would have made on the remaining $40,000 at the original interest rate and maturity, and the monthly payment the homeowner is now required to make on the new lower interest rate and extended maturity, is a debt service reduction, and

· payments in the final 10 years (that is, after the originally scheduled maturity) will be scheduled payments.

deficient valuation: For a mortgage loan, a valuation by a court of competent jurisdiction of the mortgaged property in an amount less than the then-outstanding indebtedness under the mortgage loan, or a reduction in the scheduled monthly principal payment that results in a permanent forgiveness of principal, which valuation or reduction results from a proceeding under the Bankruptcy Code or any similar state law.

delegated servicer: A person or persons, including a special servicer, to whom CitiMortgage delegates some or all of its

servicing obligations pursuant to section 4.5.

Depository: The bank or banks or savings and loan association or associations or trust company or companies (which may be the Trustee or which may be Citibank, N.A. or a Citibank banking affiliate ) at which the certificate account, buydown account, escrow account, custodial account for P&I and servicing account are established or maintained pursuant to section 3.2, 3.3 or 3.3.

Interest at the pass-through rate will be computed on the basis of a 360-day year, each month being assumed to have 30 days. The monthly pass-through rate will be one-twelfth of the pass-through rate.

(Any partial remittance of interest at such rate by reason of a full principal prepayment is based upon annual interest at that rate on the prepaid principal balance of the related mortgage loan, multiplied by a fraction the numerator of which is the actual number of days elapsed in the month of the prepayment to the date of the prepayment, and the denominator of which is 360. For affiliated mortgage loans, and some or all of the third-party mortgage loans, the mortgagor is not required to pay interest on a partial principal prepayment that is received during a month. The amounts required to be paid pursuant to section 3.4 are in addition to any interest payments made by mortgagors and passed through on full and partial prepayments.)

(iii) Immediately before the transfer and assignment of the mortgage loans to the Trustee, CMSI has good title to, and is the sole legal owner of, each mortgage loan (except as set forth in clause (v) below) and immediately upon the transfer and assignment, CMSI will have taken all steps necessary so that the Trustee will have good title to, and will be the sole legal owner of, each mortgage loan (except as set forth in clause (v) below);

(iv) As of the cut-off date, no payment of principal of or interest on any mortgage loan was 30 days or more past due (a mortgage loan being considered 30 days past due in a given month when payment due on the first day of the prior month has not been made on or before the last day of such prior month) or has been 30 days or more past due more than once for the twelve months preceding the cut-off date;

(v) As of the closing date, there is no mechanics’ lien or claim for work, labor or material affecting the mortgaged property that is or may be a lien prior to, or equal with, the lien of the mortgage except those that are insured against by the title insurance policy referred to in (x) below;

(vi) As of the closing date, there is no delinquent tax or assessment lien against any mortgaged property;

(vii) As of the closing date, there is no valid offset, defense or counterclaim to any mortgage note or mortgage, including the obligation of the mortgagor to pay the unpaid principal and interest on the mortgage note;

(viii) As of the closing date, each mortgaged property is free of material damage and is in good repair;

(ix) Each mortgage at the time it was originated complied in all material respects with applicable state, local and federal laws, including, without limitation, all applicable usury, equal credit opportunity, recording, disclosure and predatory lending laws. No mortgage loan is a high cost loan under the predatory lending law of any jurisdiction in which a mortgaged property is located, no mortgage loan is a “High Cost Loan” or “Covered Loan,” as such terms are defined in the current version of Standard & Poor’s LEVELS® Glossary, (Version 5.7 Revised, Appendix E), and no mortgage loan originated on or after October 1, 2002 through March 6, 2003 is governed by the Georgia Fair Lending Act;

(x) A lender’s title insurance policy or binder approved as such by ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac, or other assurance of title

customary in the relevant jurisdiction, was issued on the date of the origination of each mortgage loan (other than a mortgage loan for a cooperative apartment), and, as of the closing date, each such policy, binder or assurance is valid and in full force and effect;

(xi) The mortgage loans conform in all material respects with their descriptions in the prospectus relating to the certificates;

(xii) Each mortgage loan with an original principal balance exceeding 80% (or, for certain mortgage loans originated before 1995, 90%) of its original value is covered by primary mortgage insurance at least until its outstanding principal balance is less than or equal to 80% of the original value, either through principal payments by the mortgagor or as determined by a new appraisal delivered subsequent to origination. So long as it is in effect, the primary mortgage insurance covers losses from defaults in an amount equal to the excess, of the outstanding principal balance of the mortgage loan over 75% of the original value of the mortgage loan;

(xiii) The original principal balance of each mortgage loan was not more than 95% of the original value of the mortgage loan;

(xiv) For each buydown mortgage loan, the buydown funds deposited in the buydown account, if any, will be sufficient, after crediting interest at the rate per annum, if any, specified in the buydown agreement compounded monthly to the buydown account and adding the amounts required to be paid by the mortgagor, to make the scheduled payments stated in the mortgage note for the term of the buydown subsidy agreement;

(xv) Each mortgage loan is a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Internal Revenue Code.

The representations and warranties in this section 2.2 will survive delivery of the mortgage files to the Trustee.

2.3 Repurchase or substitution of mortgage loans

(a) Each of CMSI, CitiMortgage and the Trustee will promptly notify the other parties if it discovers a breach of any of the representations and warranties in section 2.2 that materially and adversely affects the interests of the certificate holders or any Insurer in a mortgage loan (including a mortgage loan substituted for a nonconforming mortgage loan pursuant to section 2.4) (a material breach).

(b) Pursuant to the Mortgage Document Custodial Agreement, the Mortgage Document Custodian will review each mortgage file within 90 days after the closing date to ascertain that all required documents have been executed, received and recorded, if applicable, and that such documents relate to the mortgage loans identified in exhibit B. If the Mortgage Document Custodian finds that a document in a mortgage file is missing or materially defective, the Mortgage Document Custodian will promptly notify CitiMortgage and CMSI by e-mail.

(c) If CMSI is notified of a material breach, CMSI will have 60 days after the notice (or a longer period approved in advance in writing by a Responsible Officer of the Trustee) to cure the breach in all material respects, or to repurchase the mortgage loan or substitute eligible substitute mortgage loans, as provided in this section 2.3.

If CMSI is notified by the Mortgage Document Custodian that the documentation for a mortgage loan is defective, CMSI will have 180 days after the notice to cure the breach in all material respects, or to repurchase the mortgage loan

or substitute eligible substitute mortgage loans, as provided in this section 2.3, except that CMSI will only have 90 days after the notice to cure, cure, repurchase, or substitute if the defect causes the mortgage loan to fail to be a “qualified mortgage” under Internal Revenue Code section 860G(a)(3).

(d) Any repurchase by CMSI of a mortgage loan will be at a price equal to

(i) 100% of the scheduled principal balance of the mortgage loan on the date of repurchase, plus

(ii) accrued and unpaid interest thereon at the pass-through rate to the first day of the following month, plus

(iii) any costs and damages incurred by the Trust Fund in connection with any violation by such mortgage loan of any predatory lending law, plus

(iv) aggregate outstanding advances for the mortgage loan, to the extent not recovered in (ii) above.

(e) CMSI will pay the repurchase price to CitiMortgage, which will promptly deposit the repurchase price in the certificate account. A repurchase of a mortgage loan under this section 2.3 will be considered a prepayment in full of the mortgage loan on the date of repurchase. Upon the Trustee’s receipt of written notice of the deposit signed by an Authorized Officer of CitiMortgage, the Trustee will direct the Mortgage Document Custodian to release the related mortgage file to CMSI and will execute and deliver such instruments of transfer or assignment furnished to the Trustee, in each case without recourse, as CMSI reasonably requests, to vest the mortgage loan in CMSI. Repurchase of the mortgage loan by CMSI will be deemed to include the right to receive any remittance on the mortgage loan payable or received on or after the date of repurchase, and CitiMortgage will, upon receipt, promptly pay CMSI the amount of any such remittance.

(f) CMSI may, instead of repurchasing a mortgage loan pursuant to this section 2.3, substitute one or more eligible substitute mortgage loans (as defined below) for one or more nonconforming mortgage loans. Such a substitution will take place on a business day designated by CMSI (the substitution day) occurring before the second anniversary of the startup day, subject to satisfaction of the conditions in section 2.1 and the following conditions:

(i) no Event of Default is continuing; and

(ii) the aggregate scheduled principal balance of all eligible substitute mortgage loans substituted on the substitution day (determined for each eligible substitute mortgage loan as of the substitution day) does not exceed 40% of the aggregate scheduled principal balance of all mortgage loans as of the closing date;

(g) An eligible substitute mortgage loan: is a mortgage loan

· for which all payments of principal and interest due on or before the substitution day have been received,

· that has a mortgage note rate equal to or greater than the highest mortgage note rate of any mortgage loan for which it is being substituted,

· that matures no later than, and no more than one year before, any mortgage loan for which it is being substituted,

· that has an original term to maturity equal to each mortgage loan for which it is being substituted, and

· that has a scheduled principal balance that, together with any other eligible substitute mortgage loans being substituted on that substitution day, and any funds CMSI deposits in the certificate account relating to the substitution (the substitution adjustment amount) equals or exceeds the

mortgage loans for which they are being substituted.

The substitution adjustment amount will be separately accounted for as a reserve fund in the certificate account and will be remitted to certificate holders in the month following receipt when the repurchase proceeds are remitted to compensate for the resulting shortfall incurred in connection with the substitution of mortgage loans.

(h) If, on the substitution day, any installment of principal and interest has been received in the certificate account where the principal portion has not been applied to reduce the scheduled principal balance of the mortgage loan that is being substituted for, because the installment was received before the first day of the applicable month, the full amount of such prepaid installment will be paid on the substitution day to CMSI from the certificate account.

(i) Upon a substitution of mortgage loans pursuant to this section 2.3,

· exhibit B to this agreement will be deemed to be amended to exclude all mortgage loans being replaced by such eligible substitute mortgage loans and to include, pursuant to section 10.1, the information in the supplemental mortgage loan schedule regarding the eligible substitute mortgage loans, and all references in this agreement to mortgage loans will include such eligible substitute mortgage loans,

· CMSI will be deemed to represent and warrant, as of the substitution day, that the representations and warranties in section 2.2 are true of the eligible substitute mortgage loans, and

· the Trustee will release to CMSI the nonconforming mortgage loans and execute and deliver any instruments of transfer or assignment required to transfer, without recourse, the nonconforming mortgage loans to CMSI.

(j) CMSI’s obligation under this section 2.3 to repurchase or substitute mortgage loans will be the sole remedy against CMSI available to the certificate holders or the Trustee on behalf of the certificate holders for a material defect in a mortgage document or a breach of a representation and warranty in section 2.2.

3 Servicing

3.1 CitiMortgage as servicer and master servicer

(a) Affiliated mortgage loans. CitiMortgage will service those mortgage loans listed in exhibit B, other than any mortgage loans listed on schedule B-TP (the affiliated mortgage loans).

(b) Third-party mortgage loans. The mortgage loans listed in schedule B-TP to exhibit B (third-party mortgage loans) will be serviced by a third-party servicer pursuant to this agreement, a third-party servicing agreement between CitiMortgage and the third-party servicer, and the Guide. CitiMortgage will be the master servicer for each third-party mortgage loan. Each third-party servicing agreement will be consistent with this agreement and, except for special servicing agreements, will be effective as of the closing date.

(c) Special servicing. CitiMortgage may enter into a special servicing agreement with an unaffiliated person (the class B holder). At any time that the class B holder holds 100% of the beneficial interest in the most subordinated class of certificates, the class B holder may designate a special servicer to service certain mortgage loans in default and REO property (specially serviced mortgage loans). Any special servicing agreement will be subject to each rating agency’s acknowledgement that the ratings

of the certificates in effect immediately prior to CitiMortgage’s entering into the special servicing agreement will not be qualified, downgraded or withdrawn, and that the certificates will not be placed on credit review status (except for possible upgrading) as a result of the agreement.

CitiMortgage will be the master servicer and the special servicer will be a third-party servicer for the specially serviced mortgage loans. Except as otherwise stated or as the context clearly requires, references in this agreement to third-party mortgage loans will include specially serviced mortgage loans, and references to third-party servicing agreements will include special servicing agreements.

(d) Third-party servicing. With CitiMortgage’s approval, a third-party servicer may delegate its servicing obligations, but the third-party servicer will remain obligated under its third-party servicing agreement. CitiMortgage and any third-party servicer may amend the third-party servicing agreement, consistent with this agreement.

CitiMortgage will enforce each third-party servicer’s obligations under its third-party servicing agreement, including any obligation to make advances for delinquent payments or to purchase a mortgage loan on account of defective documentation or a breach of a representation or warranty. Such enforcement, including the legal prosecution of claims, termination of third-party servicing agreements, and the pursuit of other appropriate remedies, will as to form, extent and timing be conducted as CitiMortgage, in its good faith business judgment, would require if it were the owner of the mortgage loans. CitiMortgage will pay the costs of enforcement at its own expense, but will be reimbursed only from

· a general recovery resulting from the enforcement only to the extent that the recovery exceeds all amounts due on the mortgage loans, or

· a specific recovery of costs, expenses or attorneys fees against the party against whom the enforcement is directed.

(e) Servicing generally. In connection with its servicing and master servicing, CitiMortgage

· may, acting alone or through third-party servicers, take any action it deems necessary or desirable.

· may execute and deliver on behalf of itself, the certificate holders or the Trustee any instruments of satisfaction or cancellation, or of partial or full release or discharge and all other comparable instruments, for the mortgage loans and the related mortgaged properties.

· will service and master service the mortgage loans in the best interests of, and for the benefit of, the certificate holders and any Insurer.

· will service the affiliated mortgage loans in accordance with its normal servicing procedures for mortgage loans held in its own portfolio.

· will master service the third-party mortgage loans, in accordance with prudent mortgage loan servicing standards and procedures accepted in the mortgage banking industry and in accordance with the Guide.

· will promptly notify the Trustee of any circumstance that might adversely affect CitiMortgage’s ability to service or master service any mortgage loan or to otherwise perform its obligations under this agreement.

· will maintain accurate books and records, and an adequate system of audit and internal controls, that will permit the Trustee, or its duly authorized representatives and designees, to examine and audit and make legible reproductions of records during reasonable business

hours. All such records will be maintained for the period required by the Guide or any longer period required by law.

The Trustee will furnish CitiMortgage with any powers of attorney and other documents reasonably necessary or appropriate, and will take any other actions that CitiMortgage reasonably requests, to enable CitiMortgage to carry out its servicing duties.

3.2 Collections

CitiMortgage and each third-party servicer will, to the extent consistent with this agreement,

·	follow such normal collection procedures as it deems necessary and advisable, and

·	make reasonable efforts to collect all amounts payable on the mortgage loans it services.

Consistent with the foregoing, CitiMortgage may

· waive any late payment charge, prepayment charge or penalty interest in connection with the prepayment of a mortgage loan or any assumption fees or other fees collected in the ordinary course of servicing the mortgage loan, and

· arrange with a mortgagor a schedule for the payment of principal and interest due and unpaid after the applicable first day of the month if CitiMortgage reasonably believes that without the arrangement the mortgagor would default on the mortgage loan. Regardless of whether such an arrangement is made, the mortgage loan will be considered delinquent for all purposes of this agreement.

CitiMortgage need not institute litigation to collect any payment if it reasonably believes that the cost of litigation is likely to outweigh its economic benefit.

3.3 Certificate and other accounts

(a) Certificate account. On or before the closing date, CitiMortgage will open with Depositories or the Paying Agent one or more certificate accounts (collectively, the certificate account). The certificate account will include any alternative certificate account. The certificate account will be a non-interest bearing account unless the Series Terms state that the certificate account is an investment account.

CitiMortgage will not commingle funds and other property in the certificate account with any other funds or property of CitiMortgage or the Trustee. However, in order to efficiently transfer funds in the certificate account to a distribution account, CitiMortgage may, on the business day preceding the date funds are to be transferred from the certificate account to the distribution account, transfer those funds to a commingled clearance account, provided, that if Fitch has rated the certificates, CitiMortgage may not so commingle funds unless CitiMortgage’s short-term rating, or the short-term rating of any person to whom CitiMortgage has delegated servicing under this agreement, by Fitch is at least “F1.” The clearance account will be under CitiMortgage’s sole control, and CitiMortgage will maintain adequate records indicating the ownership of the funds in the clearance account.

CitiMortgage, on behalf of the Trustee, will deposit in the certificate account, within one business day following receipt and posting, the following amounts received by it on the affiliated mortgage loans (remittances on the affiliated mortgage loans):

· all principal payments and prepayments (other than payments due, and principal prepayments received, on or before the cut-off date);

all interest payments (other than payments due on or before the cut-off date), net of any servicing fee retained by CitiMortgage pursuant to section 3.8(b);

· any buydown funds required to be deposited pursuant to section 3.16;

· all net liquidation proceeds, other than proceeds to be applied to the restoration or repair of the related mortgaged property or released to the related mortgagor in accordance with normal servicing procedures;

· proceeds from the repurchase of a mortgage loan, and the substitution adjustment amount in connection with an eligible substitute mortgage loan;

· all hazard insurance proceeds;

· any advance account advance;

· any loss recoveries; and

· the amount CitiMortgage is required to pay into the certificate account pursuant to section 3.4, “Prepayment interest shortfalls.”

If CitiMortgage must repay any amount deposited in the certificate account, by reason of the reversal of a provisional credit owing to the dishonor of a mortgagor’s check or otherwise, CitiMortgage will promptly

· withhold a corresponding amount from a subsequent deposit into the certificate account, and

· restate its accounts appropriately.

CitiMortgage need not deposit in the certificate account

·	amounts required to be deposited into the servicing account,

·	collected servicing fees, except as required by section 3.4, “Prepayment interest shortfalls,”

·	prepayment charges, late payment charges, assumption fees and other similar charges, which CitiMortgage may retain as additional servicing compensation, and

·	reimbursements of property protection expenses,

received on affiliated mortgage loans.

(b) Servicing accounts. CitiMortgage will establish and maintain servicing accounts with Depositories, and will deposit therein all collections of taxes, assessments, primary mortgage or hazard insurance premiums or comparable items for the account of the mortgagors. CitiMortgage may withdraw funds from the servicing account, but only

· to effect payment of taxes, assessments, primary mortgage or hazard insurance premiums or comparable items,

· to reimburse the relevant servicer for costs incurred in effecting the timely payment of taxes and assessments on a mortgaged property, for servicing account advances, and for payments made pursuant to section 3.1 regarding timely payment of taxes and assessments, section 3.10 regarding premiums on primary mortgage insurance policies, and section 3.11 regarding premiums on standard hazard insurance policies, or

· to refund to a mortgagor any amounts determined to be overages, or to pay interest owed to mortgagors on such account to the extent required by law, or to clear and terminate such accounts at the termination of this agreement in accordance with section 9.1.

The servicing account may commingle collections from other series that have the same Trustee. The servicing account will be a non-interest bearing account unless the Series Terms state that the servicing account is an investment account.

Any costs incurred by the relevant servicer in effecting the timely payment of taxes and assessments on a mortgaged property will not, for the purpose of calculating monthly distributions to certificate holders, be added to the amount owing under the related mortgage loan,

even if the terms of the mortgage loan so permit.

(c) Third-party accounts. CitiMortgage will establish and maintain with Depositories segregated custodial accounts for P&I and segregated escrow accounts in accordance with the requirements of the Guide. Each third-party servicer will deposit in such accounts, within two business days of receipt and posting, the amounts related to the third-party mortgage loans required by the third-party servicing agreements to be so deposited. Amounts in a custodial account for P&I will be fully insured by the FDIC or the National Credit Union Share Insurance Fund. To the extent amounts in a custodial account for P&I are not fully insured, the excess will either, at CitiMortgage’s option,

· be promptly remitted to the certificate account or a custodial investment account, or

· be secured by one or more Eligible Investments maturing not later than the determination date, provided that the Trustee has received an opinion of counsel acceptable to the Trustee to the effect that CitiMortgage has either a claim to the funds held by the institution or a perfected first security interest against such Eligible Investments superior to the claims of any other depositor or general creditor of such institution.

Proceeds received on individual third-party mortgage loans from a title, hazard or other insurance policy covering the mortgage loan, other than a primary mortgage insurance policy, will be deposited first in the applicable escrow account if required for the restoration or repair of the related mortgaged property. Proceeds from such insurance policies not so deposited in the applicable escrow account and proceeds from primary mortgage insurance policies will be deposited in the custodial account for P&I and will be applied to the balances of the related third-party mortgage loans as payments of interest and principal.

Third-party servicers may withdraw funds from custodial accounts for P&I as permitted by this agreement and in accordance with the Guide. The Trustee will have no responsibility for monitoring such withdrawals.

CitiMortgage will maintain separate accounting on a mortgage loan-by-mortgage loan basis for any remittances to or payments from the custodial accounts for P&I.

(d) Transfers from third-party accounts to certificate account. On each determination date, each third-party servicer will withdraw from its custodial accounts for P&I and deposit into the certificate account the following amounts (remittances on third-party loans):

· scheduled installments of principal and interest on the third-party mortgage loans received by the third-party servicers that were due on the first day of that month, net of third-party servicing fees due third-party servicers;

· principal prepayments and insurance proceeds, net of third-party servicing fees due third-party servicers, received in the preceding month;

· liquidation proceeds on a third-party mortgage loan.

(e) Accounts generally. The certificate account, the servicing account, each custodial account for P&I, the escrow account and the distribution account will each bear a designation clearly indicating that the funds in the account are held for the benefit of the Trustee or the certificate holders. CitiMortgage, each third-party servicer, and the Paying Agent will hold all money and property received by it as part of the Trust Fund and will apply it as

provided in this agreement, except that amounts from buydown funds required to be deposited pursuant to section 3.16 will be held by CitiMortgage in the buydown account on behalf of the mortgagors, subject to withdrawal by CitiMortgage for the purposes set forth in sections 3.6(b) and (c).

3.4 Prepayment interest shortfalls

(a) Affiliated mortgage loans. CitiMortgage will deposit in the certificate account on the business day preceding each distribution day the aggregate prepayment interest shortfall on the affiliated mortgage loans for the preceding month provided that such deposit need not exceed the lesser of

· the aggregate amount of the collected servicing fees on the affiliated mortgage loans for the month preceding such distribution day and

· one-half the scheduled servicing fee on the affiliated mortgage loans for that month.

Such deposit will not be considered to be a voluntary advance by CitiMortgage, and will not be reimbursable to CitiMortgage from the certificate account or otherwise.

(b) Third-party mortgage loans. Each third-party servicer will transfer to the certificate account on each determination date the aggregate amount required under the Guide to be paid by third-party servicers in respect of prepayment interest shortfalls on third-party mortgage loans for the preceding month.

(c) Each third-party servicer will deposit in the certificate account on the business day preceding each distribution day the aggregate prepayment interest shortfall on its third-party mortgage loans for the preceding month, provided that the aggregate of such deposits for all third-party loans for any distribution day will be reduced by any amounts paid by the third-party servicer under the preceding paragraph (b) on the preceding determination date.

3.5 Advances

(a) Servicing account advances. CitiMortgage will deposit in the servicing account the payment of property taxes and insurance premiums and other similar payments relating to the third-party mortgage loans that are not timely paid by the mortgagors or advanced by the third-party servicers on the date when such tax, premium or other cost for which such payment is intended is due.

(b) Remittance delinquencies. For each distribution day, a remittance delinquency:

· on an affiliated loan is the originally scheduled interest at the pass-through rate, and principal installment (as adjusted for any principal prepayments), on the mortgage loan due from the mortgagor on (but not before) the first day of the month but not received in the certificate account by close of business on the third business day before the distribution day.

· on a third-party loan is the originally scheduled interest at the pass-through rate, and principal installment (as adjusted for any principal prepayments), on the mortgage loan due from the mortgagor on (but not before) the first day of the month but not received in the certificate account by close of business on the determination date for the distribution day.

· on a buydown mortgage loan is the accrued and unpaid interest at the related pass-through rate, and the principal installment (as adjusted for any principal prepayments) on the mortgage loan due from the related buydown account on (but not before) the first day of the month but not received in the certificate account by close of business on (a) the third business day before the distribution day (for a buydown mortgage loan that is an affiliated

loan) or (b) the determination date (for a buydown mortgage loan that is a third-party mortgage loan).

A remittance delinquency does not include an apparent remittance delinquency that is determined by CitiMortgage to be the result of the occurrence of an extraordinary event (but not including a remittance delinquency determined to be eligible for an advance pursuant to this section 3.5).

(c) Advances by third-party servicers. To the extent required by its third-party servicing agreement, each third-party servicer will transfer to the certificate account, on the determination date, any amount required to be advanced under its third-party servicing agreement (a third-party servicer advance).

(d) Uncommitted cash advances. On the business day before each distribution day, CitiMortgage will transfer from the certificate account to the distribution account

· uncommitted cash related to affiliated mortgage loans in an amount not greater than the remittance delinquencies on the affiliated mortgage loans for that distribution day, and

· uncommitted cash relating to third-party mortgage loans in an amount not greater than the remittance delinquencies on the third-party mortgage loans for that distribution day.

(e) Voluntary advances by CitiMortgage. On the business day before each distribution day, CitiMortgage will deposit in the certificate account a voluntary advance equal to

· the sum of (i) remittance delinquencies on the mortgage loans for that distribution day, (ii) scheduled interest not required to be paid by the mortgagors on the first day of the month because of the limitations on mortgage interest payments under the federal Servicemembers Civil Relief Act or any comparable state laws, in each case after adjustment of delinquent or non-required interest payments to interest at the pass-through rate, and (iii) the amount of any uncommitted cash transferred to the distribution account for the preceding distribution day, minus

· the sum of (i) uncommitted cash transferred to the distribution account on the same day pursuant to paragraph (d) above, and (ii) any third-party servicer advances for that distribution day.

(f) Paying agent advances. Before noon on each distribution day, the Paying Agent will deposit into the distribution account an affiliated Paying Agent advance equal to

· the sum of (i) all remittance delinquencies on the affiliated mortgage loans for that distribution day, and (ii) the amount of all uncommitted cash advances related to the affiliated mortgage loans transferred to the distribution account for the preceding distribution day, minus

· the sum of (i) any uncommitted cash advance related to the affiliated mortgage loans for that distribution day and (ii) any voluntary advance by CitiMortgage related to the affiliated loans for that distribution day, other than an advance of interest not required to be paid because of the limitations on mortgage interest payments under the federal Servicemembers Civil Relief Act or any comparable state laws (Relieved interest).

Before noon on each distribution day, the Paying Agent will deposit into the distribution account a third-party Paying Agent advance equal to

· the sum of (i) all remittance delinquencies on the third-party mortgage loans for that distribution day, and (ii) the amount of uncommitted cash advances related to the third-party mortgage loans transferred to the distribution account for the preceding distribution day, minus

the sum of (i) any uncommitted cash advances related to third-party mortgage loans for that distribution day, and (ii) any third-party servicer advance, other than an advance of Relieved interest, for that distribution day.

CitiMortgage will on the business day it receives notice from the Paying Agent of the amount of any affiliated or third-party Paying Agent advance,

· pay the Paying Agent a servicing administration fee of $100 for each distribution day on which the Paying Agent makes such an advance, and

· reimburse the Paying Agent for the amount of the advance,

provided that if the notice is received after 1PM on a business day, the administration fee and reimbursement will be made to the Paying Agent by 1PM on the following business day.

Promptly after the Trust Fund is terminated pursuant to section 9, CitiMortgage will notify the Paying Agent of the amount of affiliated and third-party Paying Agent advances for which CitiMortgage reimbursed the Paying Agent and that were not recovered from later remittances, net recoveries or other proceeds or collections on the affiliated or third-party mortgage loans, respectively. The Paying Agent will reimburse CitiMortgage for the amount of reimbursements not so recovered on the next business day after its receipt of the notice.

(g) Limited obligation to make advances. Notwithstanding anything to the contrary in this agreement, the relevant servicer will not be obligated to make any advance described in sections (a) through (e) above, nor will the Paying Agent be obligated to make any advance described in section (f) above, except to the extent that the servicer or the Paying Agent determines that the advance will be recoverable from future payments and proceeds on the related mortgage loan.

CitiMortgage will provide the Paying Agent with any information CitiMortgage has and the Paying Agent requests to help the Paying Agent determine if a Paying Agent advance will be recoverable.

(h) Future moratorium legislation. If after the date of this agreement, any state or locality enacts legislation granting mortgagors a full or partial moratorium on mortgage payments while the mortgagor is on active military service, CitiMortgage, will, by notice to the Paying Agent, elect whether CitiMortgage will advance part or all of any postponed payments under such legislation. CitiMortgage will make a separate election for each state or locality that adopts such legislation. To the extent CitiMortgage elects not to advance part or all of such postponed payments, the Paying Agent will not have any obligation to advance such payments.

3.6 Distributions

(a) Transfers to distribution account. Not later than 12 noon on each distribution day, CitiMortgage will withdraw from the certificate account and deposit in a distribution account established by the Paying Agent (or to the extent provided in the Series Terms, any pooling, lower-tier or upper-tier REMIC account), all distributions to be made on the distribution day on the certificates (or class P or class L regular interests). The distribution account will be an Eligible Account, and will not be commingled with any other account.

(b) Distributions to certificate holders. On each distribution day, the Paying Agent will distribute from the distribution account (or, to the extent provided in the Series Terms, any pooling, lower-tier, or upper-tier REMIC account) to each certificate holder of

record on the preceding record date (other than as provided in section (c) below for final distributions) the certificate holder’s share (based on the denomination of certificates of the applicable class held by the holder) of the amounts distributable to such class in accordance with the priorities set forth in the Series Terms, as set forth in the applicable distribution day statement.

All reductions in principal balance of a certificate (or one or more Predecessor Certificates) effected by distributions made on any distribution day or reductions thereof without distributions in accordance with this agreement (including final distributions under section (c) below or section 9.1) will be binding upon all holders of such certificate and of any certificate issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof, whether or not the distributions are noted on the certificate.

(c) Final distributions. If CitiMortgage expects that the principal balance of any class will be reduced to zero on the next distribution day, it will, not later than the third day before that distribution day, mail to the Paying Agent and each person in whose name a certificate to be so retired is registered at the close of business on the applicable record date a notice that:

· CitiMortgage expects that funds sufficient to reduce the principal balance of the certificate to zero will be available in the certificate account on that distribution day, and

· if such funds are available, (A) a final distribution will be made on that distribution day, but only upon presentation and surrender of the certificate at the office or agency of the Paying Agent maintained for that purpose pursuant to the Series Terms (the address of which will be set forth in the notice), and (B) no interest will accrue on the certificate after the end of the month preceding the distribution day.

The final distribution on each certificate (including the final distribution on any certificate receiving a distribution in connection with a termination pursuant to section 9.1) will be payable only upon presentation and surrender of the certificate on or after the distribution day for such final distribution at the office or agency of the Paying Agent maintained for that purpose pursuant to the Series Terms.

(d) Method of payment. Each distribution will be made

·	by check mailed to the certificate holder at its address appearing in the Certificate Register, or

·	by wire transfer if the certificate holder is eligible for wire transfer under the Series Terms and the Paying Agent has received wiring instructions from the certificate holder, or

·	by such other means of payment as the certificate holder, CitiMortgage, and the Paying Agent may agree.

Wiring instructions received by the Paying Agent will remain in effect until changed by the certificate holder by written notice to the Paying Agent at least five business days before a distribution day.

(e) Unclaimed distributions. Any amounts in the distribution account that are distributable as interest or principal pursuant to this section 3.6, but are not distributed because of the non-presentation of the related certificates, or because the check for such payment is returned undelivered, will be held by the Paying Agent for two years in a separate trust account for the benefit of the holders of such certificates. Amounts in the separate account will be deemed to have been distributed to the holders for the purpose of any calculations required by this agreement and will no longer be available for

application to any other amounts due under this agreement.

After two years, any amount that remains in the separate account will be paid to the holders of the residual certificates, as appropriate (except that any amounts representing reimbursement for an insured payment will be paid to the Insurer). After such payment, the certificate holders will be required to seek payments as unsecured general creditors from the holders of the residual certificates, as appropriate.

(f) Determination of distributions. CitiMortgage will determine on each determination date, based on payments received on the mortgage loans:

· the pool distribution amount;

· the interest allocation and interest allocation carryforward for each class;

· the principal allocation for each class;

· the principal distribution for each class;

· any ratio-stripped PO class reimbursement;

· any insurance premium; and

· any other information required to determine the distributions to be made to certificate holders in accordance with the Series Terms.

(g) Distribution day data. CitiMortgage will prepare, and will deliver to the Paying Agent no later than 12 noon on the third business day before each distribution day, distribution day data for that distribution day as to:

(i) the pool distribution amount (including any portion that represents loss recoveries);

(ii) the aggregate amount of interest accrued during the related month on all outstanding certificates and any non-supported prepayment interest shortfalls;

(iii) the aggregate amount of interest to be distributed to each class, identifying the portion attributable to the class’s interest allocation carryforwards;

(iv) the aggregate distribution in reduction of principal balance to be made for each class;

(v) the amount in reduction of principal balance of the certificates that is not the result of distributions in reduction of principal balance;

(vi) whether the amount expected to be available in the certificate account will be sufficient to pay all amounts specified in clauses (iii) and (iv) above and, if not, the percentages of each such amount that may be paid in accordance with the priorities set forth in the Series Terms from the amounts expected to be available in the certificate account;

(vii) the amounts included in the statement pursuant to clauses (iii) and (iv) above, expressed in each case per $1,000 initial principal balance (or initial notional balance), to be distributed;

(viii) the aggregate amounts of affiliated servicing fee and any third-party servicing fee to be paid pursuant to section 3.6(h);

(ix) any special hazard loss limit, fraud loss limit and bankruptcy loss limit after giving effect to the distributions to be made on the distribution day;

(x) any amount to be withdrawn from the certificate account and paid over to the holders of the class PR or class LR certificates pursuant to section 3.6(h); and

(xi) the principal balance of the certificates that will remain outstanding after giving effect to the distributions to be made on the distribution day, expressed both on an aggregate basis and per $1,000 initial principal balance.

On the second business day before each distribution day, CitiMortgage will deliver to the Paying Agent a distribution day statement (which may be in electronic form), setting forth the distribution day data in statement format.

(h) Payment of servicing fees; distributions to residual holders. On each distribution day, if

·	CitiMortgage has transferred funds from the certificate account to the distribution account in accordance with section 3.6(a), and

·	the Depository for the certificate account has set aside any uncommitted cash in the certificate account that is not required for an uncommitted cash advance, the amount of which uncommitted cash CitiMortgage will certify to such Depository,

then CitiMortgage will withdraw any cash balance remaining in the certificate account, and apply it in the following order:

First, to the payment to CitiMortgage of any portion of the servicing fee not already retained pursuant to section 3.8(b); and

Second, as a distribution to the holders of any class PR, and if there are no class PR certificates, to the holders of the class LR certificates.

(i) Transfer of certificates. Subject to the foregoing provisions of this section 3.6, each certificate delivered under this agreement upon registration of transfer of or in exchange for or in lieu of any other certificate will carry the rights to unpaid distributions that were carried by the other certificate.

3.7 Third-party servicing

(a) Third-party servicing fee. As compensation for its activities under its third-party servicing agreements, each third-party servicer will be entitled to a third-party servicing fee for each third-party mortgage loan as to which a monthly installment of principal and interest is received equal to the monthly third-party servicing fee rate for the mortgage loan multiplied by the scheduled principal balance on which the installment of interest accrued. (The third-party servicer’s compensation may be reduced by any master servicing fee on such third-party mortgage loan, as described in the following paragraph (b).)

(b) Master servicing fee. CitiMortgage will be entitled to any master servicing fee that CitiMortgage and the third-party servicer may agree upon in the third-party servicing agreement, provided that the master servicing fee rate

· for a specially serviced mortgage loan may not exceed 0.25% per annum, and

· for a third-party mortgage loan other than a specially serviced mortgage loan may not exceed the per annum rate specified as the third-party servicing fee rate on schedule B-TP to exhibit B under the heading “Sub Fee.”

CitiMortgage may also be entitled to additional master servicing compensation not based on the master servicing fee rate, as agreed with the third-party servicer, such as any net REO proceeds in excess of the outstanding principal balance and accrued interest on a mortgage loan.

(c) CitiMortgage liability. Notwithstanding any third-party servicing agreement, provisions of this agreement relating to agreements or arrangements between CitiMortgage and a third-party servicer, or reference to actions taken through a third-party servicer or otherwise, CitiMortgage will remain obligated and liable to the Trustee and the certificate holders for the servicing of the third-party mortgage loans in accordance with this agreement to the same extent as though CitiMortgage alone were servicing the third-party mortgage loans itself.

All documents, instruments or contracts executed by third-party servicers on behalf of CitiMortgage will be treated by the Trustee as though executed by CitiMortgage itself.

Any amounts received by a third-party servicer for a third-party mortgage loan will

be deemed to have been received by CitiMortgage for purposes of this agreement. If a third-party servicer fails to remit any amounts it receives that are required to be transferred to the certificate account or an escrow account, CitiMortgage will transmit the required amounts to the account.

Nothing in this agreement will limit any indemnification agreement between CitiMortgage and a third-party servicer, but the indemnification agreement will not diminish CitiMortgage’s obligations or liability under this agreement.

3.8 Permitted withdrawals from certificate account

(a) CitiMortgage may pay the following amounts from the certificate account, in order of priority listed:

(i) to itself, collected servicing and master servicing fees (to the extent not withheld from payments of interest received on the mortgage loans), and, for a liquidated loan, the excess of scheduled servicing fees over the collected servicing fees;

(ii) reimbursements to itself for (A) liquidation expenses incurred on a mortgage loan, up to the liquidation proceeds on the mortgage loan deposited in the certificate account, net of applicable servicing fees, (B) any amounts due CitiMortgage under section 3.12 relating to deficiency actions, and (C) any excess of the liquidation proceeds after such reimbursement over the principal balance of the mortgage loan, together with accrued and unpaid interest at the mortgage note rate to the date of purchase at the foreclosure sale, liquidation proceeding or otherwise. For these purposes, liquidation expenses will include subsequent trailing bills relating to previously disposed REO property in which distribution of net liquidation proceeds has occurred.

(iii) reimbursement to itself for (x) voluntary advances or (y) reimbursements by CitiMortgage to the Paying Agent for Paying Agent advances. Reimbursements pursuant to this clause (iii) will be limited to amounts received on particular mortgage loans (including, for this purpose, liquidation and insurance proceeds) that represent late payments of principal or interest, or subsequent payments of interest that was excused mortgagors on military service under applicable moratorium legislation;

(iv) reimbursement to an advancing person (including CitiMortgage, to the extent CitiMortgage has reimbursed the Paying Agent for a Paying Agent advance) for voluntary or Paying Agent advances that the advancing person determines are nonrecoverable advances;

(v) reimbursement to itself for servicing account advances not previously reimbursed out of the servicing account, in each case to the extent that amounts representing reimbursements of such advances on mortgage loans may have been deposited in the certificate account;

(vi) reimbursement to an advancing person of voluntary advances, Paying Agent advances, or advance account advances, made on a mortgage loan in an amount not to exceed at any time in the aggregate the amount of payments from time to time deposited in the certificate account and not required to be distributed to the certificate holders (including, for this purpose, liquidation and insurance proceeds covering the mortgaged property);

(viii) payments to itself or the holders of the residual certificates of Investment Income;

(ix) transfers to the distribution account;

(x) payments to clear and terminate the certificate account pursuant to section 9.1; and

(xi) all remittances received following the repurchase of a mortgage loan that are required to be paid to CMSI pursuant to section 2.3.

CitiMortgage may also withdraw funds from the certificate account, and adjust the pool distribution amount for any pool or the amount of scheduled or unscheduled principal payments, to appropriately adjust for prior servicing errors, including errors in posting, allocation, or distribution, if CitiMortgage believes that such withdrawals or adjustments are necessary to effect the provisions of this agreement.

If, at the request of the Trustee, CitiMortgage delivers an officer’s certificate to the Trustee in connection with any such withdrawal or adjustment, the Trustee may conclusively rely without investigation on the officer’s certificate as to the reasons, amount and conformity to this agreement of the withdrawal or adjustment.

CitiMortgage will maintain separate accounting records, on a mortgage loan-by-mortgage loan basis, of withdrawals from the certificate account pursuant to clauses (ii), (iii), (iv), (vi), (vii), (viii) and (x) of this section; provided that such records need not be retained by CitiMortgage for a period longer than its five most recent fiscal years.

(b) In lieu of withdrawing collected or scheduled servicing fees from the certificate account pursuant to paragraph (a) above, CitiMortgage may, prior to transferring collection on mortgage loans, or liquidation or insurance proceeds, to the certificate account, withhold and pay to itself out of each payment received by it on account of interest the appropriate collected servicing fee. Any amounts that CitiMortgage is required to deposit in the certificate account pursuant to section 3.4, “Prepayment interest shortfalls,” will be deemed to reduce the collected or scheduled servicing fee to which CitiMortgage is entitled pursuant to this section.

3.9 Expenses

(a) CitiMortgage expenses. CitiMortgage will pay all expenses incurred by it in connection with its servicing and master servicing activities under this agreement, and will not be entitled to reimbursement therefor except as expressly provided in this agreement. CitiMortgage will also be liable for all expenses, liabilities and obligations of the Trust Fund (other than the obligation to make principal and interest distributions on the certificates) including those set forth in section 8.5, “Trustee’s fees and expenses.” To the extent such expenses, liabilities or obligations consist of federal income taxes, including, without limitation, prohibited transaction taxes, taxes on net income from foreclosure property and taxes on certain contributions to a REMIC after the startup day, nothing will prevent CitiMortgage from contesting any such tax, if permitted by law, pending the outcome of such proceedings.

(d) Third-party servicer expenses. Each third-party servicer will pay all expenses incurred by it in connection with its servicing activities under its third-party servicing agreement (including advance payment of premiums for primary mortgage insurance policies, if required) and will not be entitled to reimbursement therefor except as expressly provided in its third-party servicing agreement.

3.10 Primary mortgage insurance

CitiMortgage will exercise its best reasonable efforts to maintain each primary mortgage insurance policy in full force. CitiMortgage will present claims to the insurer, and take any other reasonable action that may be necessary to permit recovery, under any primary mortgage

insurance policy for a defaulted mortgage loan.

CitiMortgage may substitute for any primary mortgage insurance policy another substantially equivalent policy issued by another insurer, provided that no such substitution will be made unless (i) CitiMortgage is advised by each rating agency that the substitution will not negatively affect the rating agency’s then-current rating of the certificates (for any insured class certificates, without regard to any certificate insurance policy) or (ii) the claims-paying ability of the substitute primary mortgage insurer is, at the time of substitution, rated at least “AA” or its equivalent by each rating agency rating the certificates.

3.11 Hazard insurance

CitiMortgage will maintain for each mortgage loan (other than a mortgage loan for a cooperative apartment) hazard insurance with extended coverage in an amount at least equal to the lesser of

· the maximum insurable value of the improvements securing the mortgage loan if that amount is less than the unpaid principal balance on the mortgage loan,

· the principal balance owing on the mortgage loan if that amount is between 80% and 100%, inclusive, of the insurable value, or

· 80% of the insurable value if the principal balance of the mortgage loan is less than 80% of the insurable value.

Except for cooperative apartments, CitiMortgage will also maintain on property acquired upon foreclosure, or by deed in lieu of foreclosure, hazard fire insurance with extended coverage in an amount at least equal to the lesser of

· the maximum insurable value from time to time of the improvements that are a part of the property, or

· the unpaid principal balance of the mortgage loan at the time of foreclosure or deed in lieu of foreclosure plus (A) accrued interest at the mortgage note rate and (B) CitiMortgage’s good-faith estimate of liquidation expenses for the property.

If a mortgaged property is located in a federally designated flood area, the hazard insurance will include flood insurance. No earthquake or other additional insurance will be required for any property, except as required by applicable law.

CitiMortgage may maintain a blanket hazard insurance policy on all of the mortgage loans. However, if the blanket policy contains a deductible clause, CitiMortgage will deposit in the certificate account any amount not payable under the blanket policy because of the deductible clause that would have been paid under a hazard policy that meets the requirements of this section and does not have a deductible clause.

Any cost incurred by CitiMortgage in maintaining hazard insurance will not, for the purpose of calculating monthly distributions to the certificate holders, be added to the amount owing under the related mortgage loan, even if the terms of the mortgage loan permit it.

3.12 Realization on defaulted mortgage loans

CitiMortgage will use its best efforts, consistent with its customary servicing procedures, to foreclose upon or otherwise comparably convert the ownership of properties securing any mortgage loans that continue in default and as to which no satisfactory arrangements can be made for collection of delinquent payments pursuant to section 3.2. Consistent with the foregoing, CitiMortgage will use reasonable efforts to realize upon defaulted mortgage loans in a manner that will maximize the receipt of

principal and interest by the certificate holders, taking into account, among other things, the timing of foreclosure proceedings.

If a deficiency action is available against the mortgagor or any other person, CitiMortgage may proceed for the deficiency. CitiMortgage may retain 25% of the net proceeds received from a mortgagor pursuant to a deficiency action as compensation for proceeding with the deficiency action.

Any property (other than the mortgaged property) pledged by or on behalf of a mortgagor as security for a mortgage loan in default, including marketable securities, may be liquidated and the proceeds thereof applied to cover any shortfalls upon the liquidation of a mortgaged property provided that the Trust Fund will in no event acquire ownership of any such property unless the Trustee receives an opinion of counsel to the effect that such ownership will not cause any constituent REMIC to fail to qualify as a REMIC and will not subject any constituent REMIC to any tax.

If title to a mortgaged property is acquired in foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale will be issued to the Trustee, or to its nominee on behalf of the Trust Fund. Notwithstanding such acquisition of title and cancellation of the mortgage loan, the mortgage loan will (except for purposes of section 9.1) be considered an outstanding mortgage loan until the mortgaged property is sold and the mortgage loan becomes a liquidated loan. Consistent with the foregoing for purposes of all calculations hereunder so long as the mortgage loan is considered outstanding, it will be assumed that the related mortgage note and its amortization schedule in effect on and after the acquisition of title (after giving effect to any previous principal prepayments, and before any adjustment thereto by reason of any deficient valuations and debt service reductions or any similar proceeding or any moratorium or similar waiver or grace period) remain in effect (notwithstanding that the indebtedness evidenced by the mortgage note will have been discharged), subject to adjustment to reflect the application of REO proceeds received in any month.

Net REO proceeds received in any month will be deemed to have been received first in payment of the accrued interest that remained unpaid on the date that such mortgage loan became an REO loan, with any excess being deemed to have been received for delinquent principal installments that remained unpaid on such date. Thereafter, net REO proceeds received in any month will be applied to the payment of installments of principal and accrued interest on the mortgage loan deemed to be due and payable in accordance with the terms of the mortgage note and amortization schedule. If the net REO proceeds exceed the then delinquent principal and interest installments on the mortgage loan, the excess will be treated as a principal prepayment received on the mortgage loan, up to the outstanding principal balance of the mortgage loan. Any net REO proceeds in excess of the outstanding principal balance and accrued interest on the mortgage loan will be treated as additional servicing compensation for CitiMortgage.

If CitiMortgage forecloses or accepts a deed in lieu of foreclosure on a mortgaged property, CitiMortgage will dispose of the mortgaged property before the end of the third calendar year that begins after the year of acquisition by the applicable constituent REMIC, unless

· (i) the Trustee receives an opinion of counsel to the effect that the holding by the

applicable constituent REMIC of the mortgaged property subsequent to such period (and specifying the period beyond such period for which the mortgaged property may be held) will not result in the imposition of taxes on “prohibited transactions” of any of the constituent REMICs as defined in Internal Revenue Code Section 860F, or cause any of the constituent REMICs to fail to qualify as a REMIC at any time that any certificates are outstanding, in which case the applicable constituent REMIC may continue to hold such mortgaged property (subject to any conditions contained in such opinion of counsel), or

· CitiMortgage has, prior to the expiration of such period, applied to the Internal Revenue Service for an extension of the period in the manner contemplated by Internal Revenue Code Section 856(e)(3), in which case the period will be extended by the applicable period.

Notwithstanding any other provision of this agreement, unless otherwise required pursuant to applicable state law, no mortgaged property acquired by the applicable constituent REMIC will be

· rented (or allowed to continue to be rented) or otherwise used for the production of income by or on behalf of the applicable constituent REMIC in such a manner or pursuant to any terms that would (1) cause such mortgaged property to fall to qualify as “foreclosure property” within the meaning of Internal Revenue Code Section 860G(a)(8), (2) subject any of the constituent REMICs to the imposition of any federal or state income taxes on “net income from foreclosure property” earned from such mortgaged property within the meaning of Internal Revenue Code Section 860G(c), or (3) cause the sale of such mortgaged property to result in the receipt by any of the constituent REMICs of any income from non-permitted assets as described in Internal Revenue Code Section 860F(a)(2)(B), or

· sold in a manner or pursuant to terms that would subject any of the constituent REMICs to the imposition of any federal or state income taxes on “net income from foreclosure property” within the meaning of Internal Revenue Code Section 860G(c), unless CitiMortgage agrees to indemnify and hold harmless each constituent REMIC against the imposition of such taxes.

The foregoing is subject to the provision that, if any mortgaged property is damaged, whether from an uninsured cause or otherwise, CitiMortgage will not be required to expend its own funds in connection with any foreclosure or towards the restoration of such property unless it determines that

· the restoration or foreclosure will increase the net proceeds of liquidation of the mortgage loan to the certificate holders, after reimbursement to itself for such expenses, and

· CitiMortgage will recover such expenses through liquidation or insurance proceeds.

CitiMortgage will be responsible for all other costs and expenses incurred by it in any such proceedings; provided, however, that it will be entitled to reimbursement thereof from the related property, as contemplated in section 3.8. Notwithstanding the above, CitiMortgage will not be entitled to recover legal expenses incurred in connection with liquidation proceedings where the mortgagor pays all delinquent payments and expenses and the proceedings are terminated prior to liquidation, other than sums received from the mortgagor for such expenses.

Notwithstanding anything to the contrary in this section 3.12, CitiMortgage will not be obligated to foreclose upon or otherwise convert the ownership of any

mortgaged property that it believes may be contaminated with or affected by pollutants, contamination, hazardous wastes or hazardous substances. CitiMortgage will not be liable to the certificate holders if, based on its belief that no such contamination or effect exists, CitiMortgage forecloses on a mortgaged property and takes title to such mortgaged property, and the mortgaged property is later determined to be so contaminated or affected.

If CitiMortgage does not elect to foreclose on a mortgaged property, CitiMortgage may, in the exercise of its judgment, elect to accept a payment or payments, in connection with the sale by the mortgagor of the mortgaged property or the retention by the mortgagor of the mortgaged property, in aggregate amount less than the outstanding balance of the mortgage loan and accrued interest thereon.

The Trustee will furnish CitiMortgage with any powers of attorney and other documents necessary or appropriate to enable CitiMortgage to carry out its efforts in realizing upon defaulted mortgage loans hereunder.

3.13 Release of mortgage files

(a) CitiMortgage will promptly notify the Trustee of the payment in full of any mortgage loan or CitiMortgage’s receipt of notice that payment in full will be escrowed in a manner customary for such purpose, and will request delivery to it of the mortgage file. CitiMortgage’s notice will include a Servicing Officer certification that all amounts that CitiMortgage must deposit in the certificate account, in connection with the payment pursuant to section 3.3 have been or will be so deposited. Upon receipt of the certification and request, the Trustee will promptly direct the Mortgage Document Custodian to release the related mortgage documents to CitiMortgage.

For the servicing or foreclosure of any mortgage loan, including collection under a primary mortgage insurance policy, the Trustee will, upon CitiMortgage’s request and its delivery to the Trustee of a receipt signed by a Servicing Officer, direct the Mortgage Document Custodian to release the related mortgage documents to CitiMortgage. The Trustee will execute such documents furnished it as are necessary to the prosecution of any such proceedings. The receipt will obligate CitiMortgage to return the mortgage documents to the Mortgage Document Custodian when CitiMortgage no longer needs them, unless the mortgage loan has been prepaid or liquidated in the interim, in which case, upon receipt of a Servicing Officer certification similar to that described in the first paragraph of this section, the Trustee will release the receipt to CitiMortgage.

(b) CitiMortgage will record any instrument of satisfaction of the mortgage executed by it if required by applicable law, and deliver it to the person entitled thereto. CitiMortgage may not withdraw any expenses incurred in connection with the instrument of satisfaction from the certificate account.

3.14 Reports to certificate holders and others

(a) On or before each distribution day, CitiMortgage will deliver to each certificate and residual certificate holder, any Insurer, the Trustee, the Paying Agent, each rating agency and each Underwriter, a distribution report setting forth for that distribution day:

(i) for each pool, the pool distribution amount;

(ii) for each outstanding class, the interest distribution for a single certificate;

(iii) for each outstanding class, the principal distribution for a single certificate, net of any deductions for reimbursements to PO classes;

(iv) for each outstanding PO class, the amount of any reimbursements from the subordinated classes;

(v) for each outstanding class, the distribution of loss recoveries for a single certificate;

(vi) for each outstanding class, the principal or notional balance of a single certificate, and the aggregate principal or notional balance of the class, after giving effect to the distributions on the distribution day;

(vii) for each outstanding class, any increase or decrease in principal or notional balance of a single certificate since the preceding distribution day (including for each outstanding accrual class, the amount of any accrued interest added to the principal balance of a single certificate), after giving effect to the distributions on the distribution days;

(viii) for each outstanding class, any decrease in principal balance of a single certificate that is not the result of a principal distribution;

(ix) for each outstanding target-rate class, its target-rate class percentage and, for a multi-pool series, its group target rate class percentage;

(x) for each pool, the percentage of unscheduled principal payments on the pool‘s target-rate strip allocated on the distribution day to the related group’s senior target-rate classes.

(xi) for each outstanding class, any interest allocation carryforward applicable to the next succeeding distribution day;

(xii) the collected servicing fee and master servicing fee for the month preceding the month of the distribution day, as reduced, for the servicing fee, by the amount of any deposits by CitiMortgage under section 3.4 for prepayment interest shortfalls;

(xiii) for each outstanding insured class, the amount of any premiums paid to an Insurer out of remittances for the month preceding the distribution day, and any amount to be paid by an Insurer to holders of single certificates on the distribution day;

(xiv) for each pool and for the series, the aggregate amount of remittances received from the first day of the month preceding the month in which the distribution day occurs through the first day of the following month;

(xv) for each pool and for the series, any servicing account advances, voluntary and third-party servicer advances calculated as of the determination date, Paying Agent advances, advance account advances, uncommitted cash advances and any other amounts charged thereto for the applicable distribution day;

(xvi) for each pool and for the series, reimbursement for the distribution day of any servicing account advances, voluntary advances, third-party servicer advances, Paying Agent advances, advance account advances, and uncommitted cash advances for any prior distribution day;

(xvii) for each pool and for the series, the aggregate scheduled principal balance of the mortgage loans as of the last day of the month preceding the month of the distribution, after giving effect to payments on the mortgage loans due on the related first day of the month and principal prepayments distributed on the distribution day;

(xviii) for each pool and for the series, the weighted average mortgage interest rate (before deduction of the servicing fee) and the weighted average remaining term to stated maturity, after giving effect to distributions on the distribution day;

(xix) for each pool and for the series, the number and aggregate principal balance of mortgage loans delinquent 30 days and 60 or more days (as determined by CitiMortgage under the Mortgage Bankers Association method);

(xx) for each pool and for the series, the book value of any REO property; and

(xxi) any other information required for a distribution report on Form 10-D under the federal securities laws.

The distribution report will provide appropriate introductory and explanatory information to introduce any material terms, parties or abbreviations used, and shall state the applicable record, determination and distribution dates. CitiMortgage will determine the format of the distribution report, and may include additional information relating to the series if CitiMortgage believes such information may be material to certificate holders.

CitiMortgage will provide certificate holders that are federally insured savings and loan associations with certain reports, and will provide access to information and documentation regarding the mortgage loans included in the Trust Fund, sufficient to permit such associations to comply with applicable regulations of the Office of Thrift Supervision.

Any report required by this subsection (a) to be delivered to any person will be deemed delivered when it is posted to CitiMortgage’s website, www-.citimortgagembs.-com, or to any other website of which CitiMortgage gives prior notice to the person, and the person can access the statement or report on the website without paying an additional charge or subscription fee.

(b) CitiMortgage will provide the Paying Agent and the Trustee by the third business day before each distribution day with a statement of the information set forth in clauses (i) through (xii) of subsection (a), such information to be given in the aggregate.

(c) Not later than 15 business days after receipt of a written request from the Trustee, CitiMortgage will deliver to the Trustee a statement, certified by a Servicing Officer, of the aggregate of deposits in and withdrawals from the certificate account for each category of deposit specified in sections 3.3 and each category of withdrawal specified in section 3.8 for any distribution day specified by the Trustee.

(d) The Trustee may at any time during normal business hours inspect and copy at CitiMortgage’s expense CitiMortgage’s books, records and accounts for the mortgage loans.

(e) CitiMortgage will provide to any Insurer each notice, report, opinion or other written item (other than mortgage documents) delivered pursuant to the penultimate paragraph of section 2.3 and sections 2.4, 3.5, 3.6, 3.14(a), 3.19, 3.21, 3.22, 4.3, 4.4, 8.8, 9.1, 10.1, and 11.2.

3.15 Tax returns and reports

(a) For federal income tax purposes, each constituent REMIC will have a calendar year taxable year and will maintain its books on the accrual method of accounting.

(b) CitiMortgage will prepare and file with the Internal Revenue Service and applicable state or local tax authorities income tax or information returns for each taxable year for each constituent REMIC, and will furnish to certificate holders the schedules, statements or information, as required by the Internal Revenue Code or state or local tax laws, regulations or rules.

Within 30 days of the startup day, CitiMortgage will furnish to the Internal Revenue Service, on Form 8811 or as otherwise required by the Internal Revenue Code, the name, title, address, and

telephone number of the person that certificate holders may contact for tax information relating to the REMICs, together with any additional information required by the Form, and will update such information as required by the Internal Revenue Code. Income tax or information returns will be signed by the Trustee or any other person required to sign the returns by the Internal Revenue Code or state or local tax laws, regulations or rules.

(c) In the first federal income tax return for each constituent REMIC for its short taxable year ending December 31 in the year in which the startup day occurs, REMIC status will be elected for that taxable year and all succeeding taxable years.

(d) CitiMortgage will maintain records relating to each constituent REMIC, including its income, expenses, assets and liabilities, and the adjusted basis of its property as required by the Internal Revenue Code, or as necessary to prepare the foregoing returns, schedules, statements or information.

(e) Each holder of a residual certificate will be deemed to have agreed, by acceptance thereof, to be bound by this section 3.15 and by section 5.2 and by “REMIC Provisions” in the Series Terms.

3.16 Application of buydown funds

On or before the closing date if there are any buydown mortgage loans in the Trust Fund, CitiMortgage will open the buydown account with the Depository in the name of the Trustee, on behalf of the mortgagors. For each buydown mortgage loan, on the business day following receipt of the mortgagor’s required monthly payment under the buydown agreement, CitiMortgage will withdraw from the buydown account and deposit in immediately available funds in the certificate account an amount which, when added to the mortgagor’s payment, will equal the full monthly payment due under the mortgage note. No later than the fifth business day before the last business day of each month, CitiMortgage will deposit in the buydown account in immediately available funds an amount equal to interest at the rate per annum specified in the buydown agreement compounded monthly on the buydown funds for each buydown mortgage loan.

If a buydown mortgage loan is fully prepaid while buydown funds remain in the buydown account, the unpaid principal balance of the buydown mortgage loan will be reduced by the amount of the buydown funds (which reduction will constitute a principal prepayment) and, on the business day following the date of the principal prepayment, CitiMortgage will deposit the buydown funds in the certificate account. If the property securing a buydown mortgage loan is sold in liquidation of the buydown mortgage loan (either by CitiMortgage or the insurer under any related primary mortgage insurance policy) while buydown funds remain in the buydown account, the buydown funds will be (i) deposited in the certificate account on the business day following the liquidation as a reduction of the unpaid principal balance of the buydown mortgage loan or (ii) to the extent required under an applicable primary mortgage insurance policy, paid to the insurer of the mortgage loan.

3.17 Assumption and modification agreements

If a mortgagor transfers a mortgaged property that is subject to an enforceable due-on-sale clause, CitiMortgage will accelerate the maturity of the mortgage loan to the extent permissible, unless CitiMortgage reasonably believes that the due-on-sale clause is not enforceable.

If CitiMortgage reasonably believes that the mortgaged property is not subject to an enforceable due-on-sale clause, or that enforcement will adversely affect primary mortgage insurance coverage, CitiMortgage may enter into an assumption and modification agreement with the transferee of the mortgaged property, pursuant to which both the transferee and the original mortgagor will be liable on the mortgage loan, provided that

· the mortgage loan as assumed or modified meets the requirements set forth in this agreement for mortgage loans initially included in the Trust Fund,

· the mortgage loan continues to be covered by any related primary mortgage insurance and hazard insurance policy, and

· no principal, interest or other payment on the mortgage loan is reduced or postponed.

CitiMortgage will forward an original of each assumption and modification agreement to the Mortgage Document Custodian (with a copy to the Trustee) to be added to the related mortgage file, and the agreement will be considered a part of the mortgage file for all purposes to the same extent as all other documents and instruments that are part of the mortgage file. Any fee collected by CitiMortgage for entering into such an agreement will be retained by CitiMortgage as additional servicing compensation.

3.18 Refinancings and curtailments; loan modifications

(a) In addition to waivers and arrangements permitted by section 3.2, CitiMortgage may refinance affiliated or third-party mortgage loans if the refinancing arises out of a mortgagor’s request for a refinancing, modification, or other relief from the provisions of the mortgage loan.

On the business day preceding the distribution day in the month following the effective date of the refinancing of a mortgage loan pursuant to this section, CitiMortgage will deposit into the certificate account the amount of the prepayment in full of the mortgage loan (net of all voluntary advances and Paying Agent advances for the mortgage loan, which will be reimbursed to the Paying Agent or deemed reimbursed to CitiMortgage, as the case may be). Upon the Trustee’s receipt of written notification of the deposit signed by an Authorized Officer of CitiMortgage, the related mortgage file will be released, and the Trustee will comply with the provisions of section 3.13.

For the purposes of this section, a “refinancing” will include any process with a mortgagor that results in the refinanced mortgage loan being identified and serviced as a “new mortgage loan” in CitiMortgage’s books, records and servicing files. However, in connection with a partial prepayment, CitiMortgage may reduce the scheduled monthly payments on the mortgage loan so that the mortgage loan will still be paid in equal monthly installments of principal and interest, but the prepayment will not change the originally scheduled maturity date, and such modification will not be considered a “refinancing” for purposes of this section.

(b) CitiMortgage may agree with any homeowner to modify or waive any provision of a mortgage loan if the modification or waiver does not

· affect the amount or timing of any payment of principal or interest on the mortgage loan,

· in CitiMortgage’s judgment, materially impair the security for, or reduce the likelihood of timely payment of amounts due on, the mortgage loan, or

otherwise constitute a “significant modification” within the meaning of Treasury Regulations Section 1.860G-2(b).

Notwithstanding the preceding paragraph, CitiMortgage may agree with any homeowner to modify or waive any provision of a mortgage loan if

· the mortgage loan is 90 days or more past due or, in CitiMortgage’s judgment, is subject to imminent default, or

· CitiMortgage delivers to the Trustee an opinion of counsel to the effect that the modification or waiver will not affect the REMIC status of any REMIC.

CitiMortgage will within 10 business days deliver to the Mortgage Document Custodian for deposit in the related mortgage file an original signed copy of the agreement providing for the modification or waiver. If applicable law requires a modification or waiver to be recorded, CitiMortgage will (i) deliver a copy of such signed agreement to the Trustee and (ii) deliver to the Trustee such document, with evidence of notification upon receipt thereof from the public recording office.

CitiMortgage may condition any modification or waiver on the homeowner’s payment to CitiMortgage of a reasonable or customary fee for the additional services performed, together with reimbursement for CitiMortgage’s out-of-pocket expenses, in connection with the modification or waiver. CitiMortgage may retain such fees or reimbursements as additional servicing compensation.

3.19 Investment accounts

(a) Investments. CitiMortgage may invest and reinvest funds in an investment account in accordance with this section 3.19 in one or more Eligible Investments (as described below) bearing interest or sold at discount. However, no such investment may mature later than the business day immediately preceding the next distribution day, except, that investments (including repurchase agreements) on which the Paying Agent, in its commercial capacity, is the obligor may mature on the next distribution day.

The Trustee and CitiMortgage will deposit in the certificate account immediately upon receipt all proceeds from investment of funds and disposition of assets in the certificate account. Any loss resulting from such investment will be charged to the certificate account.

CitiMortgage may, from time to time, withdraw from any investment account (other than the certificate account), any Investment Income therein, and pay same to itself, the seller or the holders of the residual certificates, as applicable.

CitiMortgage will not invest funds in the certificate account or sell an investment held in an investment account unless the investment:

· is made in the name of the Trustee (in its capacity as such) or a Qualified Nominee of the Trustee, and

· is a “cash flow investment” as defined in Internal Revenue Code Section 860G(a)(6).

CitiMortgage will not dispose of any Eligible Investment prior to its maturity. However, if sufficient uninvested funds are not available in the certificate account to make a required disbursement, CitiMortgage may sell or otherwise convert to cash a sufficient amount of the investments in the certificate account if, prior to such sale or conversion, CitiMortgage receives

(i) an opinion of counsel (which opinion may not be provided by an employee of CitiMortgage or of an affiliate of CitiMortgage) that the sale or conversion will not constitute a “prohibited transaction” under Internal Revenue Code Section 860F(a), or

(ii) if the sale or conversion constitutes such a “prohibited transaction,” (A) the consent of the holders of 100% percentage interest of the residual certificates to the prohibited transaction together with each such holder’s proportionate share of any tax imposed on the Trust Fund attributable to the transaction, and (B) an opinion of counsel (which opinion may not be provided by an employee of CitiMortgage or of an affiliate of CitiMortgage) that the transaction will not disqualify any constituent REMIC as a REMIC.

The Trustee will not have any liability for any loss incurred in connection with any investment or any sale or liquidation thereof pursuant to this agreement, unless caused by its negligence or willful misconduct, or for any insufficiency in the certificate account or the buydown account, except for losses on investments that are liabilities of the Trustee in its commercial capacity.

(b) Custodial investment account. Prior to the business day preceding the distribution day, CitiMortgage may deposit the amounts required to be transferred on the determination date from the custodial accounts for P&I in a separate account in the name of CitiMortgage and the Trustee (such account will be maintained in the trust department of a Depository and will bear a designation clearly indicating that the principal of all investments in such account is held for the benefit of the Trustee on behalf of the certificate holders) (the custodial investment account) for investment only in one or more Eligible Investments. CitiMortgage will bear any and all losses incurred on any investments made with such funds and will be entitled to retain all gains realized on such investments as additional compensation for its services as master servicer. The amount of any losses incurred in respect of any such investments will be deposited in the custodial investment account by CitiMortgage out of its own funds immediately as realized. Any successor master servicer appointed pursuant to this agreement will not be responsible for losses attributable to its predecessor. No investments held in the custodial investment account will mature later than the business day preceding the distribution day.

(i) direct obligations of, and obligations fully guaranteed by, the United States of America, ▇▇▇▇▇▇▇ Mac, ▇▇▇▇▇▇ ▇▇▇, the Farm Credit Banks, the Federal Home Loan Banks, the Student Loan Marketing Association (but only for obligations backed by letters of credit or senior obligations) or any agency or instrumentality of the United States of America the obligations of which are backed by the full faith and credit of the United States of America; provided, however, that any obligation of, or guaranteed by, the Federal Home Loan Banks or the Farm Credit Banks or any obligation of, or guaranteed by, ▇▇▇▇▇▇▇ Mac or ▇▇▇▇▇▇ ▇▇▇, other than a senior debt obligation of ▇▇▇▇▇▇▇ Mac or ▇▇▇▇▇▇ ▇▇▇ or a mortgage participation or pass-through certificate guaranteed by ▇▇▇▇▇▇▇ Mac or ▇▇▇▇▇▇ ▇▇▇, excluding stripped mortgage securities which are valued greater than par on the portion of unpaid principal, will be an Eligible Investment only if, at the time of investment, each rating agency confirms in writing that such investment is acceptable;

(ii) Federal Funds, demand and time deposits in, certificates of deposits of, or bankers’ acceptances issued by, any depository institution or trust company (including the Trustee or any agent of the Trustee, acting in their respective

commercial capacities) incorporated under the laws of the United States of America or any state thereof and subject to supervision and examination by federal or state banking authorities, so long as at the time of such investment or contractual commitment providing for such investment the certificate of deposit or other unsecured short-term debt obligations of such depository institution or trust company have a maturity of not more than one year and a credit rating of not less than “A-1+” (“A-1” if the maturity is not greater than 30 days) by S&P if S&P is a rating agency, “P-1” by Moody’s if ▇▇▇▇▇’▇ is a rating agency, and “F-1” by Fitch if Fitch is a rating agency; each such investment being expressly authorized and deemed authorized by a certificate holder’s purchase or acceptance of any certificate when acting in the capacity of a fiduciary (including a “fiduciary” of an “employee benefit plan” subject to ERISA, as those term are defined in Sections 3(21) and 3(3) of ERISA, respectively) which purchase or acceptance will also evidence and be deemed to evidence any such certificate holder’s representation and warranty to CitiMortgage, the Certificate Registrar and the Trustee and any agent of the Trustee that such certificate holder is duly authorized by and empowered under appropriate governing instruments (for example, an employee benefit plan, in the case of an ERISA fiduciary) to give such authorization; and money market funds investing exclusively in any of the investments discussed in this definition of Eligible Investments with a rating of not less than “A-1+” (“A-1” if the maturity is not greater than 30 days) by S&P if S&P is a rating agency, “F-1” by Fitch if Fitch is a rating agency, and “P-1” by Moody’s if ▇▇▇▇▇’▇ is a rating agency;

(iii) repurchase obligations for (A) any security described in clause (i) above or (B) any other security issued or guaranteed by an agency or instrumentality of the United States of America the obligations of which are backed by the full faith and credit of the United States of America, in either case where such security has a remaining maturity of one year or less and where such repurchase obligation has been entered into with a depository institution or trust company (acting as principal) with a rating of not less than “A-1+” by S&P if S&P is a rating agency, “P-1” by Moody’s if ▇▇▇▇▇’▇ is a rating agency, and “F-1” by Fitch if Fitch is a rating agency;

(iv) securities bearing interest or sold at a discount issued by any corporation incorporated under the laws of the United States of America or any state thereof which have a maturity not greater than 30 days and an unsecured long-term debt rating of at least “AA” if S&P is a rating agency, “AA” if Fitch is a rating agency, and “Aa” if ▇▇▇▇▇’▇ is a rating agency, or an unsecured short-term debt rating, of at least “A-1” if S&P is a rating agency, “F-1” if Fitch is a rating agency, and “P-1” if ▇▇▇▇▇’▇ is a rating agency, at the time of such investment or contractual commitment providing for such investment; provided, however, that securities issued by any particular corporation will not be Eligible Investments to the extent that investment therein will cause the then outstanding principal balance of securities issued by such corporation and held as part of the Trust Fund to exceed 10% of the aggregate current principal balance of certificates outstanding and of the current percentage interest of the residual certificates outstanding, and the aggregate principal balance of all cash and Eligible Investments, held in the Trust Fund;

(v) commercial paper (including both non-interest-bearing discount obligations and interest-bearing obligations payable on demand or on a specified date not more than one year after the date of issuance thereof) having at the time of such investment a rating of not less than “A-1+” (“A-1” if the maturity is not greater than 30 days and such commercial paper does not exceed 20% of the then current balance of the certificates) by S&P if S&P is a rating agency, “F-1” by Fitch if Fitch is a rating agency, and “P-1” by Moody’s if ▇▇▇▇▇’▇ is a rating agency;

(viii) any other money market deposit, obligation, security or investment bearing interest or sold at a discount which has an unsecured short-term debt rating of at least “A-1+” (“A-1” if the maturity is not greater than 30 days and such investments do not exceed 20% of the then scheduled principal balance of the mortgage loans) if S&P is a rating agency, “F-1” if Fitch is a rating agency, and “P-1” if ▇▇▇▇▇’▇ is a rating agency, or if such investment relates to a money market fund, such fund must be rated in the highest rating category by each rating agency (which, for S&P, is “AAAm” or “AAAm-G”); and

(ix) any other demand or time deposit, obligation, security or investment bearing interest or sold at a discount that each rating agency confirms in writing is acceptable;

provided, that each such Eligible Investment is a “permitted investment” as defined in Internal Revenue Code Section 860G(a)(5).

3.20 Paying Agent and Certificate Registrar

(a) Paying Agent. CitiMortgage or the Trustee may remove a Paying Agent, and CitiMortgage, with the Trustee’s approval, may appoint another Paying Agent.

A Paying Agent

the Trustee an instrument in which the Paying Agent agrees with the Trustee that the Paying Agent will have all the rights and obligations of a Paying Agent under this agreement.

(b) Certificate Registrar. CitiMortgage or the Trustee may remove a Certificate Registrar, and CitiMortgage, with the Trustee’s approval, may appoint another Certificate Registrar.

3.21 Exchange Act reporting

(a) CitiMortgage, as servicer, will prepare and file all reports required to be filed by CMSI, as depositor, under the Exchange Act (other than Forms 10-K), including required periodic reports on Form 10-D, and any required current report on Form 8-K. CMSI authorizes CitiMortgage to sign and file such reports on behalf of CMSI. CMSI will file all required Forms 10-K.

(b) For each calendar year for which CMSI is required to file a Form 10-K with the Securities and Exchange Commission for this series, each party to this agreement who

· participates in the servicing function, within the meaning of section 1122 of Regulation AB under the Securities Act (Regulation AB), for this series, or who controls such a participant, will submit, or will cause such controlled participant to submit, by March 1 of the following year, a report on an assessment of compliance covering the servicing criteria set forth opposite its name on schedule 1, “Servicing criteria to be addressed in report on assessment of compliance” (as such schedule may be modified pursuant to section 3.22(c) below), and an attestation report of a registered public accounting firm, all as required by and in full conformity with the requirements of rule 1122, and

The fees of the independent accountants and any successor will be paid by CitiMortgage as servicer, or by any successor servicer.

4 CitiMortgage

4.1 Liability of CitiMortgage and others

Each of CitiMortgage, CMSI and Citibank, N.A. will be liable under this agreement to any person or to the certificate holders only to the extent of obligations specifically undertaken by CitiMortgage, CMSI or Citibank, N.A. in this agreement.

Neither CitiMortgage, CMSI nor Citibank, N.A., nor any of their directors, officers, employees and agents will be liable to the Trust Fund or the certificate holders for any action, or for refraining from taking any action, pursuant to this agreement, or for errors in judgment, provided, however, that neither CitiMortgage, CMSI, Citibank, N.A., nor any such person will be protected against any liability that would otherwise be imposed for willful misfeasance, bad faith or gross negligence in the performance, or for reckless disregard, of their obligations under this agreement. CitiMortgage, CMSI, Citibank, N.A. and any of their directors, officers, employees or agents may rely on any document prima facie properly executed and submitted by any person as to any matters arising under this agreement.

CitiMortgage, CMSI, Citibank, N.A., and each of their directors, officers, employees and agents will be indemnified and held harmless by the Trust Fund against any loss, liability or expense incurred in connection with any actual or threatened legal or regulatory proceedings relating to this agreement or the certificates, other than a loss, liability or expense incurred by reason of willful misfeasance, bad faith or gross negligence in the performance, or reckless disregard, of their obligations under this agreement.

CitiMortgage need not appear in, prosecute or defend any legal action that is not incidental to its duties to service the mortgage loans in accordance with this agreement and that in its opinion may involve it in any expense or liability. CitiMortgage may, however, undertake any such action it deems desirable to enforce or secure the rights and duties of the parties or the interests of the certificate holders. CitiMortgage’s legal expenses and costs of such action and any resulting liability will be expenses, costs and liabilities of the Trust Fund, for which CitiMortgage will be reimbursed out of the certificate account.

Notwithstanding the foregoing, CitiMortgage will indemnify, defend and hold harmless the Trustee and the Trust Fund against any damages, claims or liabilities arising out of any violation (or claimed violation) prior to the closing date of any predatory lending law.

4.2 Assumption of CitiMortgage’s obligations by affiliate

Any corporation into which CitiMortgage is merged or consolidated, or that results from a merger, conversion or consolidation involving CitiMortgage, or that succeeds to the business of CitiMortgage, or more than 50% of the voting stock of which is, directly or indirectly, owned by Citigroup Inc., and that executes an agreement of assumption to perform all of CitiMortgage’s obligations under this agreement, will be CitiMortgage’s successor under this agreement, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. Such agreement of assumption will not, however, release CitiMortgage from any of its obligations or liabilities under this agreement.

4.3 Maintenance of office or agency

CMSI shall maintain or cause to be maintained at its expense an office or offices or agency or agencies where the certificates may be surrendered for registration of transfer or exchange and where notices and demands to or upon CMSI in respect of the certificates and this agreement may be served. CMSI initially appoints the Certificate Registrar designated in the Series Terms as its office for purposes of receipt of notices and demands. CMSI will give prompt written notice to CitiMortgage, the Trustee and the certificate holders of any change in the location of the Certificate Register or any such office or agency.

4.4 Servicer not to resign

Subject to sections 4.2 and 4.5, CitiMortgage will not resign as servicer without the consent of the Trustee, any Insurer, the holders of more than 2/3 of the voting interests of the outstanding certificates and 2/3 of the percentage interests of the residual certificates, except upon a determination that the performance of its duties hereunder is no longer permissible under applicable law. Any such determination permitting the resignation of CitiMortgage as Servicer will be supported by an opinion of counsel to such effect delivered to the Trustee. No resignation by CitiMortgage will become effective until the Trustee or a successor servicer and master servicer have assumed CitiMortgage’s obligations in accordance with section 7.2.

4.5 Delegation of duties

CitiMortgage may without notice or consent delegate any of its servicing duties, and any rights relating to such duties, to any person or persons, including a person more than 50% of whose stock is owned, directly or indirectly, by Citigroup Inc.; provided that each such person that services any mortgage loans has been approved as a seller/servicer by the Federal Housing Administration, GNMA, ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac, and has been approved in writing by the rating agencies. Such delegation will not, however, relieve CitiMortgage of its responsibility for such duties. Each delegee of CitiMortgage’s servicing duties will have those powers and duties that are granted to or required of CitiMortgage as servicer or master servicer under this agreement for such duties, subject to the limitations imposed by the agreement between CitiMortgage and such delegee.

4.6 Errors and omissions insurance

CitiMortgage will maintain in force

· a policy or policies of insurance covering errors and omissions in the performance of its servicing obligations, and

· a fidelity bond for its officers, employees and agents.

Such policies and bond will, together, comply with ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac requirements for persons servicing mortgage loans purchased by such association.

5 The certificates

5.1 The certificates

(a) The certificates and residual certificates will be substantially in the forms set forth in exhibit A. The certificates will be issued in the denominations specified in the Series Terms and will be executed by manual or facsimile signature on behalf of CMSI by its Chairman, President, one of its Vice Presidents, or one of its Assistant Vice Presidents. Certificates bearing the manual or facsimile signatures of individuals who were authorized to sign on behalf of CMSI when the signatures were affixed will bind CMSI, even if prior to the authentication and delivery of the certificates some of the individuals ceased to be authorized or to hold such offices.

No certificate will be entitled to any benefit under this agreement, or be valid for any purpose, unless it authenticated substantially in the form set forth in exhibit A. The authentication must be manually signed by the Trustee or an Authenticating Agent appointed pursuant to section 8.12, and such signature will be conclusive evidence, and the only evidence, that the certificate has been duly authenticated and delivered. All certificates will be dated the date of their authentication.

(b) Upon original issuance, book-entry certificates will be issued in the form of one or more typewritten certificates, to be delivered to the initial Clearing Agency, by, or on behalf of, CMSI. Such certificates will initially be registered on the Certificate Register in the name of the nominee of the initial Clearing Agency, and will bear a legend in substantially the following form:

“Unless this certificate is presented by an authorized representative of [the Clearing Agency] to Citicorp Mortgage Securities, Inc. or its agent for registration of transfer, exchange, or payment, and any certificate issued is registered in the name of [the Clearing Agency nominee] or such other name as requested by an authorized representative of [the Clearing Agency] (and any payment is made to [the Clearing Agency nominee] or to such other entity as is requested by an authorized representative of [the Clearing Agency]), any transfer, pledge, or other use hereof for value or otherwise by or to any person is wrongful inasmuch as the registered owner hereof, [the Clearing Agency nominee], has an interest herein.”

No beneficial owner will receive a definitive certificate representing such beneficial owner’s interest in the book-entry certificates, except as provided in section 5.6. Until definitive certificates have been issued to beneficial owners pursuant to section 5.6:

(i) This section 5.1(b) will be in full force and effect.

(ii) CMSI, the Certificate Registrar and the Trustee may deal with the Clearing Agency for all purposes (including distributions on the book-entry certificates and actions by the holders of book-entry certificates) as the authorized representative of the beneficial owners.

(iii) To the extent that this section 5.1(b) conflicts with any other provision of this agreement, this section 5.1(b) will control.

(iv) The rights of beneficial owners will be exercised only through the Clearing Agency and will be limited to those established by law, the rules, regulations and procedures of the Clearing Agency and agreements between such beneficial owners

and the Clearing Agency or the Clearing Agency Participants. For book-entry certificates, references in this agreement to

· actions by certificate holders will refer to actions taken by the Clearing Agency upon instructions from the Clearing Agency Participants, and

· distributions, notices, reports and statements to certificate holders will refer to distributions, notices, reports and statements to the Clearing Agency or its nominee, as registered holder of the book-entry certificates for the distribution to beneficial owners in accordance with the procedures of the Clearing Agency.

(v) The initial Clearing Agency will make book-entry transfers among the Clearing Agency Participants, and will receive and transmit distributions of principal and interest on the certificates to the Clearing Agency Participants, for distribution to the beneficial owners or their nominees.

For purposes of any provision of this agreement requiring or permitting actions with the consent of, or at the direction of, holders of book-entry certificates evidencing specified voting interests, such direction or consent will be given by beneficial owners having the requisite percentage interests.

Until definitive certificates are issued to beneficial owners pursuant to section 5.6, copies of the reports or statements referred to in section 3.14 will be available to beneficial owners upon written request to the Trustee at the corporate trust office or, if Citibank, N.A. is the Paying Agent, at the website referred to in section 3.14.

5.2 Registration of transfer and exchange of certificates

(a) CMSI will maintain at its expense an office or offices or agency or agencies where the certificates may be surrendered for registration of transfer or exchange and where notices and demands to or upon CMSI relating to the certificates and this agreement may be served. CMSI initially appoints the Certificate Registrar designated in the Series Terms as its office for purposes of receipt of notices and demands.

CMSI will maintain a Certificate Register at such office in which, subject to such reasonable regulations as it prescribes, CMSI will provide for the registration and transfer of certificates. CMSI will give prompt written notice to the Trustee and to the certificate holders of any change in the location of the Certificate Register or any such office or agency.

Upon surrender for registration of transfer of any certificate at the office or agency, CMSI will execute and the Trustee or the Authenticating Agent will authenticate and deliver, in the name of the designated transferee or transferee, one or more new certificates in authorized denominations of the same aggregate number of single certificates or the same aggregate percentage interest, as the case may be.

At the option of the certificate holder, certificates may be exchanged for other certificates of authorized denominations evidencing the same aggregate number of single certificates or the same aggregate percentage interest, as the case may be, upon surrender of the certificates to be exchanged at the office or agency. CMSI will execute and the Trustee or Authenticating Agent will authenticate and deliver the certificates that the certificate holder is entitled to receive.

Every certificate surrendered for registration of transfer or exchange will be accompanied by a written instrument of transfer in form satisfactory to the Trustee, CMSI and the Certificate Registrar, duly

executed by the holder or his attorney duly authorized in writing.

No service charge will be made for any registration of transfer or exchange of certificates, but the Certificate Registrar may require a payment sufficient to cover any tax or governmental charge imposed in connection with the transfer or exchange.

All certificates surrendered for registration of transfer and exchange will be canceled and, subject to the record retention requirements of the Exchange Act, subsequently destroyed by the Trustee or, at its direction, by the Certificate Registrar.

The Certificate Registrar will provide the Paying Agent and the Trustee by the third business day before each distribution day, the names and addresses of each certificate holder as of the record date and the number of single certificates or percentage interest it holds of record.

(b) Notwithstanding the foregoing section 5.2(a), no legal or beneficial interest in all or any portion of a residual certificate may be transferred, directly or indirectly, to a “disqualified organization“ within the meaning of Internal Revenue Code Section 860E(e)(5), or to an agent of a disqualified organization (including a broker, nominee, or other middleman) (an Agent) and any such purported transfer will be void and of no effect. Further, no legal or beneficial interest in all or any portion of a residual certificate may be registered in the name of a Plan or a person investing the assets of a Plan (such Plan or person an ERISA Prohibited holder) or in the name of a person that is not (i) a U.S. person or (ii) a non-U.S. person that holds the residual certificate in connection with the conduct of a trade or business within the United States and has furnished the transferor, the Certificate Registrar, and the Trustee with an effective Internal Revenue Service Form W-8ECI or (iii) a non-U.S. person that has delivered to the transferor, the Certificate Registrar, and the Trustee an opinion of a nationally recognized tax counsel to the effect that the transfer of the residual certificate to it is in accordance with the requirements of the Internal Revenue Code and that such transfer of the residual certificate will not be disregarded for federal income tax purposes (any such person who is not described in clauses (i), (ii) or (iii) above being referred to herein as a “Non-permitted Foreign holder”). Furthermore, no legal or beneficial interest in all or any portion of a residual certificate may be transferred, directly or indirectly, to a foreign permanent establishment or fixed base, within the meaning of an applicable income tax treaty, of the transferee or any other person. CMSI will not execute and the Trustee or Authenticating Agent will not authenticate and deliver, a new residual certificate in connection with any transfer of a residual certificate, and neither CMSI, the Certificate Registrar nor the Trustee will accept a surrender for transfer or registration of transfer, or register the transfer of, any residual certificate unless the transferor will have provided to CMSI, the Certificate Registrar and the Trustee an affidavit, substantially in the form of Appendix 1 hereto, signed by the transferee, to the effect that the transferee is not such a disqualified organization, an agent for any entity as to which the transferee has not received a substantially similar affidavit, an ERISA Prohibited holder, a Non-permitted Foreign holder, or a person for whom income on the residual certificate is attributed to a foreign permanent establishment or fixed base, within the meaning of an applicable income tax treaty, of the transferee or any other person, accompanied by a written statement signed by the transferor to the effect that, as of the time of the transfer, the transferor has no actual knowledge that such affidavit is

false. Upon notice by CMSI that any legal or beneficial interest in any portion of a residual certificate has been transferred, directly or indirectly, to a disqualified organization or an Agent in contravention of the foregoing restrictions, the Trustee will furnish to the Internal Revenue Service and the transferor of such residual certificate or to such Agent, within 60 days of the request therefor by such transferor or such Agent, and CMSI agrees to provide the Trustee with the computation of such information necessary to the application of Internal Revenue Code Section 860E(e) as may be required by the Internal Revenue Code, including but not limited to the present value of the total anticipated excess inclusions for such residual certificate (or portion thereof) for periods after such transfer. At the election of CMSI, the reasonable cost of computing and furnishing such information may be charged to the transferor or such Agent; however, the Trustee and CMSI will in no event be excused from furnishing such information. Every holder of a residual certificate will be deemed to have consented to such amendments to this agreement as may be required to further effectuate the restrictions on transfer of residual certificates to a disqualified organization, an Agent, an ERISA Prohibited holder or a Non-permitted Foreign holder.

The affidavit described in the preceding paragraph will also contain the statement of the transferee that it (i) has historically paid its debts as they have come due and intends to do so in the future, (ii) understands that it may incur liabilities in excess of cash flows generated by the residual certificate, (iii) intends to pay taxes associated with holding the residual certificate as they become due, (iv) will not cause the income for the residual certificate to be attributable to a foreign permanent establishment or fixed base, within the meaning of an applicable income tax treaty, of the transferee or any other person and (v) will not transfer the residual certificate to any person or entity that does not provide a similar affidavit. The transferor’s statement to the Trustee and the Certificate Registrar accompanying the affidavit will state that, after conducting a reasonable investigation of the financial condition of the transferee, the transferor has no knowledge or reason to know that the statements made by the transferee for clauses (i) and (iii) of the preceding sentence are false. Each residual certificate will bear a legend referring to the restrictions contained in this paragraph and the preceding paragraph.

Notwithstanding the foregoing, no transfer of any private certificate may be made unless such private certificate has been registered under the Securities Act and applicable state securities or “blue sky” laws, or an exemption from the Securities Act and applicable state securities or “blue sky” laws is available. Upon surrender for registration of transfer of any private certificate, (1) neither the Trustee nor the Certificate Registrar will accept surrender for transfer or registration of transfer of, or register the transfer of, any private certificate and (2) CMSI will not execute, and neither the Trustee nor the Authenticating Agent will authenticate and deliver, any new private certificate in connection with the transfer of any private certificate, unless either (A) such private certificate has been registered under the Securities Act and applicable state securities or “blue sky” laws, or (B) exemptions from the registration requirements of the Securities Act and applicable state securities or “blue sky” laws are available, and the transferee delivers to CMSI, the Trustee and the Certificate Registrar a letter substantially to the effect set forth in exhibit

D to this agreement and (1) if such transferee is not a “Qualified Institutional Buyer” within the meaning of Rule 144A of the Securities Act, and if so requested by CMSI, an opinion of counsel acceptable to CMSI will have been delivered to CMSI, the Trustee, and the Certificate Registrar, to the effect that such transfer is in compliance with either subclause (A) or subclause (B) of this clause (i) of this section 5.2; or (2) if such transfer is to a non-institutional investor, unless such investor is an accredited investor (as defined in Regulation D under the Securities Act) and has a net worth (exclusive of primary residence) of at least $1,000,000 as confirmed in writing to the Trustee and the Certificate Registrar.

No transfer of an ERISA Restricted Certificate may be made unless any proposed transferee (i) executes a representation letter in substantially the form of exhibit E hereto and in substance satisfactory to the Trustee, the Certificate Registrar and CMSI either stating (a) that it is not, and is not acting on behalf of, any employee benefit plan subject to Title I of ERISA or Section 4975 of the Internal Revenue Code, or a governmental plan, as defined in Section 3(32) of ERISA, subject to any federal, state or local law (Similar Law) which is, to a material extent, similar to the foregoing provisions of ERISA or the Internal Revenue Code (collectively, a “Plan”) or using the assets of any such Plan to effect such purchase or (b) as to the class B-4, class B-5 and class B-6 certificates only, it is an insurance company and the source of funds used to purchase the class B-4, class B-5 or class B-6 certificates is an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTE 95-60”), 60 Fed. Reg. 35925 (July 12, 1995)) and there is no Plan for which the amount of such general accounts reserves and liabilities for the contracts) held by or on behalf of such Plan and all other Plans maintained by the same employer (or affiliate thereof as defined in Section V(a)(1) of PTE 95-60) or by the same employee organization, exceed 10% of the total of all reserves and liabilities of such general account (as such amounts are determined under Section I(a) of PTE 95-60) at the date of acquisition or (ii) provides (A) an opinion of counsel in form and substance satisfactory to the Trustee, the Certificate Registrar and CMSI that the purchase or holding of ERISA Restricted Certificate by or on behalf of such Plan will not result in the assets of the Trust being deemed to be “plan assets” and subject to the prohibited transaction provisions of ERISA and the Internal Revenue Code or Similar Law and will not subject CMSI, the Trustee or the Certificate Registrar to any obligation in addition to those undertaken in this agreement and (B) such other opinions of counsel, officers’ certificates and agreements as CMSI, the Trustee or the Certificate Registrar may require in connection with such transfer.

5.3 Mutilated, destroyed, lost or stolen certificates

· any mutilated certificate is surrendered to the Certificate Registrar, or the Certificate Registrar receives evidence to its satisfaction of the destruction, loss or theft of any certificate,

· each of CMSI, the Certificate Registrar and the Trustee receive such security or indemnity as it requires to save it harmless, and

· neither the Certificate Registrar nor the Trustee is notified that the certificate has been acquired by a protected purchaser under Article 8 of the Uniform Commercial

Code as in effect in the applicable jurisdiction,

then CMSI will execute and the Trustee or Authenticating Agent will authenticate and deliver, in exchange for or in lieu of such mutilated, destroyed, lost or stolen certificate, a new certificate of like tenor and initial principal balance, initial notional balance or percentage interest. In connection with the issuance of any new certificate under this section 5.3, the Certificate Registrar may require a payment sufficient to cover any tax or other governmental charge imposed and any other expenses (including the fees and expenses of the Trustee and the Certificate Registrar) in connection with the issuance. Any duplicate certificate issued pursuant to this section 5.3 will constitute complete and indefeasible evidence of ownership in the Trust Fund, as if originally issued on the closing date, whether or not the lost, stolen or destroyed certificate is found at any time.

5.4 Persons deemed owners

Prior to due presentation of a certificate for registration of transfer, CMSI, the Trustee, any Insurer, the Certificate Registrar and any agent of CMSI, the Trustee or the Certificate Registrar may treat the person in whose name the certificate is registered as the owner of the certificate for the purpose of receiving distributions pursuant to section 3.6 and for all other purposes whatsoever, and neither CMSI, the Trustee, any Insurer, the Certificate Registrar nor any agent of CMSI, the Trustee or the Certificate Registrar will be affected by any notice to the contrary.

5.5 Access to list of certificate holders’ names and addresses

If the Trustee is not the Certificate Registrar and requests CMSI or the Certificate Registrar to provide a list of the names and addresses of certificate holders, CMSI or the Certificate Registrar will furnish to the Trustee, within 15 days after receipt of the request, a list as of the most recent record date, in such form as the Trustee reasonably requires.

If three or more certificate holders

· request such information in writing from the Trustee,

· state that they desire to communicate with other certificate holders regarding their rights under this agreement or under the certificates, and

· provide a copy of the communication they propose to transmit,

then the Trustee will, within five business days after the receipt of the request, afford the certificate holders access during normal business hours to the most recent list held by the Trustee, if any. If such list is as of a date more than 90 days prior to the date of receipt of the certificate holders’ request, the Trustee will promptly request from CMSI or the Certificate Registrar a current list and will afford the certificate holders access to the list promptly upon its receipt by the Trustee. Every certificate holder, by receiving and holding a certificate, agrees that neither CMSI, the Certificate Registrar nor the Trustee will be held accountable by reason of the disclosure of any such information as to the list of the certificate holders, regardless of the source from which the information is derived.

5.6 Definitive certificates

· DTC advises the Trustee and the Certificate Registrar in writing that the Clearing Agency is no longer willing or able properly to discharge its responsibilities as depository for the book-entry certificates, and

· CMSI is unable to locate a qualified successor,

the Certificate Registrar will notify the beneficial owners, through the Clearing Agency, of the occurrence of such event and of the availability of definitive certificates to beneficial owners requesting them. Upon surrender to the Certificate Registrar by the Clearing Agency of the certificates held of record by its nominee, accompanied by re-registration instructions and directions to execute and authenticate new certificates from CMSI, the Trustee or the Authenticating Agent will execute and authenticate definitive certificates for delivery. CMSI will arrange for, and will bear all costs of, the printing and issuance of the definitive certificates. Neither CMSI, the Trustee, the Certificate Registrar nor the Authenticating Agent will be liable for any delay in delivery of such instructions by the Clearing Agency and may conclusively rely on, and will be protected in relying on, such instructions.

5.7 Notices to Clearing Agency

Whenever notice or other communication to the holders of book-entry certificates is required under this agreement, until definitive certificates are issued to beneficial owners pursuant to section 5.6, the Trustee will deliver such notices and communications to the Clearing Agency.

6 [Reserved]

7 Default

7.1 Events of Default

If any of the following events (Events of Default) is continuing:

(a) CitiMortgage, as servicer or master servicer, fails to make a full payment, deposit, transfer or distribution required of it in such capacities under this agreement, and the failure continues unremedied for

· 10 business days after the Trustee gives written notice of the failure to CitiMortgage, or the holders of the Required Amount of certificates give written notice of the failure to CitiMortgage and the Trustee, if the failure results from an error in calculating the amount of the required deposit, transfer or distribution, or

· three business days after such notice if the failure results from any other reason; or

(b) CitiMortgage fails to reimburse a Paying Agent advance as required by section 3.5, and the failure is not remedied for 60 business days after the Trustee or the Paying Agent gives CitiMortgage written notice of the failure, or the holders of the Required Amount of Certificates give CitiMortgage and the Trustee such notice; or

(c) CitiMortgage fails to observe or perform in any material respect any other covenant or agreement of CitiMortgage set forth in the certificates or in this agreement, and the failure

· materially and adversely affects the rights of the certificate holders, and

· continues unremedied for 60 business days after the Trustee gives CitiMortgage written notice of the failure, requiring the failure to be remedied, or the holders of the Required Amount of Certificates give such notice to CitiMortgage and the Trustee; or

(d) a court or agency or supervisory authority having jurisdiction enters a decree or order for the appointment of a conservator, receiver or liquidator for CitiMortgage in any insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceeding, or for the winding up or liquidation of CitiMortgage’s affairs, and the decree or order continues unstayed and in effect for 60 consecutive days; or

(e) CitiMortgage consents to the appointment of a conservator, receiver or liquidator in an insolvency, readjustment of debt, marshaling of assets and liabilities, or

similar proceeding for CitiMortgage or substantially all of its property, or CitiMortgage admits in writing its inability to pay its debts generally as they become due, files a petition to take advantage of any applicable insolvency or reorganization statute, makes an assignment for the benefit of its creditors, or voluntarily suspends payment of its obligations;

then the Trustee or the holders of the Required Amount of certificates, by notice in writing to CitiMortgage (and to the Trustee if given by the certificate holders) may terminate all of CitiMortgage’s rights and obligations as servicer of the affiliated mortgage loans and as master servicer of the third-party mortgage loans under this agreement. Upon CitiMortgage’s receipt of such notice, all CitiMortgage’s authority under this agreement, whether for the certificates or the mortgage loans or otherwise, will pass to and be vested in the Trustee pursuant to this section 7.1, and the Trustee will be authorized to execute and deliver, on behalf of CitiMortgage as attorney-in-fact or otherwise, any documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice, whether to complete the transfer and endorsement of the mortgage loans and related documents or otherwise. CitiMortgage will cooperate with the Trustee in effecting the termination of CitiMortgage’s responsibilities and rights hereunder, including the transfer to the successor servicer for the administration by it of all cash amounts held by CitiMortgage for deposit, or deposited by CitiMortgage, in the certificate account or servicing account or subsequently received on the mortgage loans. In addition to any other amounts that are then payable, or, notwithstanding the termination of its activities as servicer and master servicer of the mortgage loans, may become payable to CitiMortgage under this agreement, CitiMortgage will be entitled to receive out of any delinquent interest payment on a mortgage loan, due before such termination notice but received afterwards, that portion of the payment that it would have received if the notice had not been given.

7.2 Trustee to act; appointment of successor

Once CitiMortgage receives a notice of termination under section 7.1, the Trustee will be the successor in all respects to CitiMortgage in its capacity as servicer and master servicer, and will be subject to all CitiMortgage’s rights and obligations under this agreement. As compensation, the Trustee will, except as provided in section 7.1, be entitled to the same compensation (whether payable out of the certificate account or otherwise) as CitiMortgage would have been entitled to under this agreement if no such notice of termination had been given. However, the Trustee may, if it is unwilling so to act, or will, if it is legally unable so to act, appoint, or petition a court of competent jurisdiction to appoint, an established housing finance institution with a net worth of not less than $5 million and approved as seller/servicer by GNMA, ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac as the successor to CitiMortgage in the assumption of all or any part of the rights and obligations of CitiMortgage under this agreement. Until such a successor is appointed, unless the Trustee is prohibited by law from so acting, the Trustee will act in such capacity as provided above. The Trustee may make such arrangements for compensation of such successor out of payments on the mortgage loans as it and the successor agree; provided, however, that no such compensation will exceed CitiMortgage’s compensation under this agreement. The

Trustee and the successor will take any actions, consistent with this agreement, necessary to effect the succession.

The Trustee will promptly notify the certificate holders and any Insurer of any termination of CitiMortgage or appointment of a successor pursuant to this section 7.

8 The Trustee

8.1 Duties

(a) Unless the Trustee has notice that an Event of Default is continuing, the Trustee will only have those obligations that are specifically set forth in this agreement, and no implied covenants of the Trustee will be read into this agreement.

(b) If the Trustee has notice that an Event of Default is continuing, then notwithstanding anything to the contrary in this agreement, the Trustee will exercise those rights and powers vested in it by this agreement, and use the same degree of care and skill in their exercise, as a prudent man would exercise under the circumstances in the conduct of his own affairs. If the Trustee is incorporated or organized under the laws of the State of New York, then, in considering what actions are prudent in the circumstances, the Trustee will consider, to the extent applicable, the matters enumerated in Section 126(2)(a) through (e) of the New York Real Property Law, as in effect on the date of this agreement, and will comply with subdivisions (3),(4) and (5) of Section 126 of the New York Real Property Law, as in effect on the date of this agreement.

The Trustee will not be charged with notice of an Event of Default (other than a default in payment to the Trustee) unless a Responsible Officer of the Trustee obtains actual knowledge of such failure or receives written notice of such Event of Default at its corporate trust office from CitiMortgage or the holders of the Required Amount of Certificates.

(c) The Trustee, upon receipt of all resolutions, certifications, statements, opinions, reports, documents, orders or other instruments that are specifically required or requested to be furnished to the Trustee pursuant to this agreement (each a Furnished Document), will examine them to determine whether they conform to the requirements of this agreement. The Trustee may request an officer’s certificate as to any matter of fact if the Trustee believes it desirable that the fact be established before the Trustee takes an action under this agreement. Unless the Trustee has notice that an Event of Default is continuing, the Trustee may conclusively rely, without investigation, on the truth of the statements and the correctness of the opinions expressed in any Furnished Document that the Trustee believes to be genuine, signed or presented by the proper parties, and in conformity with the requirements of this agreement.

The Trustee will investigate the facts or matters stated in a Furnished Document if the holders of the Required Amount of Certificates request such investigation in writing. CitiMortgage will pay, or will reimburse the Trustee upon demand, for the reasonable expense of such investigation. If the Trustee believes that the payment within a reasonable time of the costs and liabilities likely to be incurred in the investigation are not reasonably assured to it, the Trustee may, as a condition to conducting such investigation, require reasonable indemnity from the certificate holders against such expense or liability. Nothing in this clause (c) will derogate from CitiMortgage’s obligation to observe any applicable law prohibiting disclosure of information regarding the mortgagors.

(d) The Trustee will not be required to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties under this agreement, or in the exercise of any of its rights or powers, if the Trustee reasonably believes that the repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(e) Except to the extent that the Trustee becomes a successor servicer to CitiMortgage under sections 4.3 or 7.2, the Trustee will have no responsibility for the performance or the manner of performance of any of CitiMortgage’s obligations under this agreement. The relationship of CitiMortgage to the Trustee under this agreement is intended by the parties to be that of an independent contractor and not that of a joint venturer, partner or agent.

(f) The Trustee may appoint agents (which may include CitiMortgage and its affiliates) to perform any of the Trustee’s obligations under this agreement. Such agents will have all of the rights and obligations of the Trustee conferred on them by such appointment, but the Trustee will continue to be responsible for its obligations under this agreement.

8.2 Liability

(a) In performing its obligations under this agreement, the Trustee will be liable for its own negligence or misconduct, except that the Trustee will not be liable for

· an error of judgment by a Responsible Officer of the Trustee, unless the Trustee was negligent in ascertaining the pertinent facts;

· an action by the Trustee believed by it to be permitted under this agreement; and

· an action taken in accordance with the direction of the holders of the Required Amount of certificates relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this agreement.

(b) The Trustee may consult with counsel, and an opinion of counsel will be full and complete authorization and protection for any action by the Trustee taken under this agreement in accordance with such opinion.

(c) The Trustee will not be responsible for the selection of the Mortgage Document Custodian, or any Note Custodian, Paying Agent, Certificate Registrar, or Authenticating Agent, nor for their performance of their obligations under this agreement, the Mortgage Document Custodial Agreement, or any other applicable agreement.

8.3 Trustee not liable for certificates or mortgage loans

The recitals contained herein and in the certificates (other than the certification of authentication on the certificates) will be taken as the statements of CitiMortgage, and the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this agreement, the Mortgage Document Custodial Agreement or of the certificates (other than the certification of authentication on the certificates) or of any mortgage loan or related document. The Trustee will not be accountable for the use or application by CitiMortgage of any of the certificates or of the proceeds of such certificates or for the use or application of any funds paid to CitiMortgage in respect of the mortgage loans or deposited in or withdrawn from the certificate account or servicing account by CitiMortgage. The Trustee will have no liability for any losses incurred as a result of

any failure of the Trust Fund to qualify as the specified separate constituent REMICs,

· any termination, inadvertent or otherwise, of the status of the Trust Fund as the specified separate constituent REMICs,

· any tax on prohibited transactions imposed by Internal Revenue Code Section 860F(a)(1),

· any tax on net income from foreclosure property imposed by Internal Revenue Code Section 860G(c),

· any tax on contributions to any constituent REMIC after the startup day imposed by Internal Revenue Code Section 860G(d),

· any erroneous calculation or determination or any act or omission of CitiMortgage hereunder or

· any erroneous information included in any federal, state or local income tax or information return prepared pursuant to section 3.16;

provided, that the Trustee will not be excused hereby from liability for its own negligence, bad faith or failure to perform its duties as specified herein.

8.4 Trustee may own certificates

The Trustee in its individual or any other capacity may become the owner or pledgee of one or more of the certificates with the same rights as it would have if it were not Trustee and may otherwise deal with CitiMortgage or any of its affiliates as if it were not the Trustee.

8.5 Trustee’s fees and expenses

The Trustee’s fees and expenses (and those of any co-trustee appointed pursuant to section 8.10), and of any Certificate Registrar, Mortgage Document Custodian, Depository, Paying Agent, Authenticating Agent appointed pursuant to section 8.12, and agent of the Trustee appointed pursuant to section 8.2(g), will be paid by CitiMortgage, as servicer, in accordance with section 3.9(a). Citibank, N.A., as Paying Agent, has agreed to a fee of $3,000 a year. CitiMortgage will also pay any expenses associated with the resignation or removal of the Trustee and the appointment of a successor Trustee.

In consideration of paying the amounts payable pursuant to this section 8.5, CitiMortgage may retain any trustee fee that may be payable on the third-party mortgage loans. The Trustee (and any such co-Trustee) will be entitled to reasonable compensation (which will not be limited by any provision of law with respect to the compensation of a trustee of an express trust) for all services rendered by them in the execution of the trust or trusts hereby created and in the exercise and performance of any of the powers and duties hereunder of the Trustee, and upon notice to CitiMortgage, the Trustee will be paid or reimbursed by CitiMortgage for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this agreement (including the reasonable compensation and the expenses and disbursements of its counsel and of all persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence or bad faith or which is the responsibility of the certificate holders hereunder.

The Trustee, each Certificate Registrar, each Note Custodian, each Mortgage Document Custodian, each Depository, each Paying Agent, each Authenticating Agent and any agent appointed pursuant to section 8.2 are entitled to indemnification from CitiMortgage, as servicer or master servicer, and will be held harmless against any loss, liability or expense incurred without negligence or bad faith on their part, arising out of or in connection with the acceptance or administration of the trust or

trusts hereunder, including the costs and expenses of defending themselves against any claim or liability in connection with the exercise or performance of any of their powers or duties hereunder. Such indemnification will survive the payment of the certificates and termination of the Trust Fund, as well as the resignation or removal of CitiMortgage as servicer (if such action which caused the need for the indemnification occurred while CitiMortgage acted as servicer), and for purposes of such indemnification neither the negligence nor bad faith of any of the entities enumerated in the preceding sentence, nor of any Note Custodian or Mortgage Document Custodian, will be imputed to, or adversely affect, the right of any other entity enumerated in the preceding sentence to be entitled to indemnification.

8.6 Eligibility requirements for Trustee

The Trustee hereunder will at all times be a corporation or a national banking association, other than an affiliate of CitiMortgage, having its principal office in, and organized and doing business under the laws of, the United States of America or a state thereof, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus of at least $30 million, and subject to supervision or examination by federal or state authority. If such corporation or national banking association publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this section 8.6, the combined capital and surplus of such corporation or national banking association will be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If the Trustee ceases to be eligible in accordance with the provisions of this section 8.6, the Trustee will resign immediately in the manner and with the effect specified in section 8.7.

8.7 Resignation or removal of Trustee

The Trustee may resign and be discharged from the trusts hereby created by giving written notice thereof to CitiMortgage. Upon receiving such notice of resignation, CitiMortgage will promptly appoint a successor Trustee by written instrument, in duplicate, one copy of which instrument will be delivered to the resigning Trustee and one copy to the successor Trustee. If no successor Trustee will have been so appointed and having accepted appointment within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee ceases to be eligible in accordance with the provisions of section 8.6 and will fail to resign after written request therefor by CitiMortgage, or if the Trustee is legally unable to act, or is adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its property is appointed, or any public officer takes charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conversion or liquidation, then CitiMortgage may remove the Trustee. If it removes the Trustee under the authority of the immediately preceding sentence, CitiMortgage will promptly appoint a successor Trustee by written instrument, in duplicate, one copy of which instrument will be delivered to the Trustee so removed and one copy to the successor Trustee.

The Trustee may also be removed (i) by CitiMortgage, (a) if the Trustee ceases to be eligible to continue as such under this

agreement or if the Trustee becomes insolvent, (b) if the Trustee breaches any of its duties under this agreement which materially adversely affects the certificate holders, (c) if through the performance or nonperformance of certain actions by the Trustee, the rating assigned to the certificates would be lowered or (d) if the credit rating of the Trustee is downgraded to a level which would result in the rating assigned to the certificates to be lowered; or (ii) by the holders of certificates evidencing more than 50% of the voting interest of the certificates then outstanding and more than 50% of the percentage interests of the residual certificates.

Any resignation or removal of the Trustee and appointment of a successor Trustee pursuant to any of the provisions of this section 8.7 will not become effective until acceptance of appointment by the successor Trustee as provided in section 8.8.

8.8 Successor trustee

Any successor Trustee appointed as provided in section 8.7 will execute, acknowledge and deliver to CitiMortgage and to its predecessor Trustee an instrument accepting such appointment hereunder, and thereupon the resignation or removal of the predecessor Trustee will become effective and such successor Trustee, without any further act, deed or conveyance, will become fully vested with all the rights, powers, duties and obligations of its predecessor hereunder with like effect as if originally named as Trustee. The predecessor Trustee will deliver to the successor Trustee all mortgage files and related documents and statements held by it hereunder; and, if any mortgage notes or mortgage documents are then held by the Mortgage Note Custodian or Mortgage Document Custodian, respectively, pursuant to a Mortgage Document Custodial Agreement, the predecessor Trustee and the Mortgage Note Custodian or the Mortgage Document Custodian, as the case may be, will amend such Mortgage Document Custodial Agreement to make the successor Trustee the successor to the predecessor Trustee thereunder; and CitiMortgage and the predecessor Trustee will execute and deliver such instruments and do other such things as may reasonably be required for fully and certainly vesting and confirming in the successor Trustee all such rights, powers, duties and obligations.

No successor Trustee will accept appointment as provided in this section 8.8 unless at the time of such acceptance such successor Trustee will be eligible under the provisions of section 8.6.

Upon acceptance of appointment by a successor Trustee as provided in this section 8.8, CitiMortgage will mail notice of the succession of such Trustee hereunder to all holders of certificates at their addresses as shown in the Certificate Register, and to any Insurer. If CitiMortgage fails to mail such notice within 10 days after acceptance of appointment by the successor Trustee, the successor Trustee will cause such notice to be mailed at the expense of CitiMortgage.

8.9 Merger or consolidation of Trustee

Any corporation or national banking association into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation or national banking association resulting from any merger, conversion or consolidation to which the Trustee will be a party, or any corporation or national banking association succeeding to all or substantially all of the corporate trust business of the Trustee, will be the successor of the Trustee hereunder, provided such corporation or national banking association will be eligible under

the provisions of section 8.6, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding.

8.10 Appointment of co-trustee or separate trustee

Notwithstanding any other provisions of this agreement, for the purpose of meeting any legal requirements of any jurisdiction in which any part of the Trust Fund or property securing any mortgage note may at the time be located, CitiMortgage and the Trustee acting jointly will have the power and will execute and deliver all instruments to appoint one or more persons approved by the Trustee to act as co-trustee or co-trustees jointly with the Trustee, or separate trustee or separate trustees, of all or any part of the Trust Fund, and to vest in such person or persons, in such capacity and for the benefit of the certificate holders and any Insurer, such title to the Trust Fund, or any part thereof, and, subject to the other provisions of this section 8.10, such powers, duties, obligations, rights and trusts as CitiMortgage and the Trustee may consider necessary and desirable. If CitiMortgage will not have joined in such appointment within 15 days after the receipt by it of a request so to do, or in the case an Event of Default will have occurred and be continuing, the Trustee alone will have the power to make such appointment. No co-trustee or separate trustee hereunder will be required to meet the terms of eligibility as a successor trustee under section 8.6 and no notice to the certificate holders of the appointment of any co-trustee or separate trustee will be required under section 8.8.

Every separate trustee and co-trustee will, to the extent permitted by law and by the instrument appointing such separate trustee or co-trustee, be appointed and act subject to the following provisions and conditions:

(a) All rights, powers, duties and obligations conferred or imposed upon the Trustee will be conferred or imposed upon and exercised or performed by the Trustee and such separate trustee or co-trustee jointly (it being understood that such separate trustee or co-trustee is not authorized to act separately without the Trustee joining such act), except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed (whether as Trustee hereunder or as successor to CitiMortgage hereunder), the Trustee will be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations (including the holding of title to the Trust Fund or any portion thereof in any such jurisdiction) will be exercised and performed singly by such separate trustee or co-trustee, but solely at the direction of the Trustee;

(b) No trustee hereunder will be held personally liable by reason of any act or omission of any other trustee hereunder; and

(c) CitiMortgage and the Trustee acting jointly may accept the resignation of or remove any separate trustee or co-trustee.

Any notice, request or other writing given to the Trustee will be deemed to have been given to each of the then separate trustees and co-trustees, as effectively as if given to each of them. Every instrument appointing any separate trustee or co-trustee will refer to this agreement and the conditions of this section 8. Each separate trustee and co-trustee, upon its acceptance of the trusts conferred, will be vested with the estates or property specified in its instrument of appointment, either jointly with the Trustee or separately, as may be provided therein, subject to all of the

provisions of this agreement relating to the conduct of, affecting the liability of, or affording protection to, the Trustee. Every such instrument will be filed with the Trustee and a copy thereof given to CitiMortgage.

Any separate trustee or co-trustee may constitute the Trustee, its agent or attorney-in-fact, with full power and authority, to the extent not prohibited by law, to do any lawful act under or in respect of this agreement on its behalf and in its name. If any separate trustee or co-trustee will die, become incapable of acting, resign or be removed, all of its estates, properties, rights, remedies and trusts will vest in and be exercised by the Trustee to the extent permitted by law, without the appointment of a new or successor trustee.

8.11 Tax returns

The Trustee, upon request, will furnish CitiMortgage with all such information as may be reasonably required in connection with the preparation of all federal, state and local income tax or information returns of each constituent REMIC. The Trustee will sign the federal and, if applicable, state and local income tax returns of each constituent REMIC.

8.12 Appointment of authenticating agent

As long as any of the certificates remain outstanding the Trustee may appoint an Authenticating Agent or Agents (which may include CitiMortgage or any of its affiliates) which will be authorized to act on behalf of the Trustee to authenticate certificates, and certificates so authenticated will be entitled to the benefit of this agreement and will be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference made in this agreement to the authentication and delivery of certificates by the Trustee or the Trustee’s certification of authentication, such reference will be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certification of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent will be acceptable to CitiMortgage and will at all times be a corporation or national banking association organized and doing business under the laws of the United States of America, any state thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $15 million, authorized under such laws to conduct a trust business and subject to supervision or examination by federal or state authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this section 8.12, the combined capital and surplus of such Authenticating Agent will be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If an Authenticating Agent ceases to be eligible in accordance with the provisions of this section 8.12, such Authenticating Agent will resign immediately in the manner and with the effect specified in this section 8.12.

Any corporation or national banking association into which an authenticating Agent may be merged in or converted or with which it may be consolidated, or any corporation or national banking association resulting from any merger, conversion or consolidation to which such Authenticating Agent will be a party, or any corporation or national banking association succeeding to the corporate agency or corporate trust business of an Authenticating Agent, will

100

continue to be an Authenticating Agent, provided such corporation or national banking association will be otherwise eligible under this section 8.12, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

9 Termination

9.1 Termination upon repurchase by CMSI or liquidation of all mortgage loans

The obligations and responsibilities of CMSI, CitiMortgage and the Trustee under, and the Trust Fund created by, this agreement will terminate upon

(a) the repurchase by CMSI of all of the mortgage loans and all property acquired in respect of any mortgage loan remaining in the Trust Fund, or

(b) the later of (i) the maturity or other liquidation (or any advance with respect thereto) of the last mortgage loan remaining in the Trust Fund and the disposition of all property acquired upon foreclosure or by deed in lieu of foreclosure of any mortgage loan and (ii) the payment to the certificate holders and to the Insurer, as subrogee of any insured class certificates, of all amounts required to be paid to them pursuant to this agreement;

provided, however, that in no event will the trust created hereby continue beyond the expiration of 21 years from the death of the last survivor of the lawful descendants of ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, the late Ambassador of the United States of America to the Court of St. James’s, living on the date of this agreement.

CMSI’s right to repurchase all of the mortgage loans on any distribution day

101

pursuant to clause (a) above will be conditioned upon

· the aggregate scheduled principal balances of such mortgage loans, at the time of any such repurchase and after giving effect to distributions to be made on such distribution day, aggregating an amount less than 10% of the aggregate scheduled principal balance of the mortgage loans as of the closing date, which amount is set forth in the Series Terms and

· any other condition set forth in the Series Terms.

The repurchase of the mortgage loans and other property under clause (a) above will be at a price equal to the sum of

· 100% of the unpaid principal balance of each mortgage loan on the first day of the month of repurchase (after giving effect to payments of principal due on such first day) plus accrued interest at the pass-through rate for each mortgage loan to but not including the first day of the month in the month in which the related distribution is made to certificate holders, after the deduction of (x) unreimbursed voluntary advances, affiliated Paying Agent advances, third-party Paying Agent advances, and advance account advances (other than such payments and advances in respect of interest in excess of the pass-through rate on the mortgage loans) made prior to the month of repurchase, whereupon such voluntary advances, affiliated Paying Agent advances, third-party Paying Agent advances and advance account advances will be reimbursed to the Paying Agent or deemed reimbursed to CitiMortgage, as the case may be, by such deductions, and (y) the aggregate amount of any non-supported prepayment interest shortfalls for the distribution day in the month of such repurchase, and

· the appraised value of any acquired property in the Trust Fund (less the good faith estimate of CitiMortgage of liquidation expenses to be incurred in connection with its disposal thereof), such appraisal to be conducted by an appraiser mutually agreed upon by CitiMortgage and the Trustee.

Notwithstanding anything to the contrary in this section 9.1, if the purchase price of the mortgage loans under clause (a) above would be less than the aggregate fair market value of the mortgage loans on the first day of the month of repurchase (after giving effect to payments of principal due on such first day), then CMSI may so repurchase the mortgage loans only if the repurchase would be permitted under then-applicable risk-based capital rules applicable to securitizations treated as sales.

Any method of termination or repurchase of the Trust Fund other than as provided in clauses (a) or (b) above must be based on the receipt by the Trustee of an opinion of counsel (who may not be an employee of CMSI or of an affiliate of CMSI) or other evidence that such termination and repurchase will be part of a “qualified liquidation” within the meaning of Internal Revenue Code Section 860F(a)(4)(A), will not adversely affect the status of the Trust Fund as separate constituent REMICs under the Internal Revenue Code and will not otherwise subject the Trust Fund to any tax. CMSI may transfer its right to repurchase all of the mortgage loans pursuant to clause (a) above to any third party of choice.

Such termination will occur only in connection with a “qualified liquidation” of each constituent REMIC within the meaning of Internal Revenue Code Section 860F(a)(4)(A), pursuant to which the Trustee will sell or otherwise dispose of all of the remaining assets of the Trust Fund and make all required distributions to certificate holders within 90 days of the adoption of a plan of complete liquidation. For this purpose, the notice of termination

102

described in the next paragraph will be the adoption of a plan of complete liquidation described in Internal Revenue Code Section 860F-(a)(4)-(A)(i), which will be deemed to occur on the date the first such notice is mailed. Such date will be specified in the final federal income tax return of each constituent REMIC constituted by the Trust Fund.

Notice of a termination, specifying the distribution day upon which the certificate holders may surrender their certificates to the Paying Agent for payment of the final distribution and cancellation, will be given promptly by the Trustee by letter to the certificate holders mailed not earlier than 30 days nor more than 60 days prior to such distribution day specifying

·	the distribution day upon which final payment of the certificates will be made upon presentation and surrender of the certificates at the office of the Paying Agent designated in the notice,

·	the amount of the final distribution, and

·	that the record date otherwise applicable to such distribution day will not apply, and that distributions will be made only upon presentation and surrender of the certificates at the designated office of the Paying Agent.

CMSI will give such notice to the Trustee and, if applicable, the Certificate Registrar, the Mortgage Document Custodian and the Paying Agent at the time the notice is given to the certificate holders.

If such notice is given, CMSI will deposit in the certificate account or the account designated by the Paying Agent, on the business day preceding the distribution day for the final distribution, an amount equal to the final distribution on the certificates. Upon certification to the Trustee by an Authorized Officer of CMSI following such final deposit, and delivery by CMSI of an opinion of counsel to the effect that all conditions set forth in this section 9.1 have been met, the Trustee will promptly release to CMSI the mortgage files for the mortgage loans.

If all of the certificate holders do not surrender their certificates for cancellation within six months after the date specified in the notice, the Trustee will give a second written notice to the remaining certificate holders to surrender their certificates for cancellation and receive the final distribution. If all the certificates have not been surrendered for cancellation within one year after the second notice, the Trustee may take appropriate steps to contact the remaining certificate holders concerning surrender of their certificates, and the cost thereof will be paid out of the funds and other assets which remain subject hereto. Interest will not accrue for the period of any delay in the payment of a certificate resulting from the failure of a holder to surrender the certificate in accordance with the notice.

10 General provisions

10.1 Amendments

This Agreement may be amended by the parties, without the consent of any of the certificate holders,

· to cure an ambiguity or inconsistency, or to correct a mistake,

· to add provisions not inconsistent with this agreement,

· to comply with any requirements imposed by the Internal Revenue Code,

· to establish a “qualified reserve fund” within the meaning of Internal Revenue Code Section 860G(a)(7)(B), or

· to maintain the status of the Trust Fund as separate constituent REMICs.

This Agreement may also be amended by the parties, without certificate holder consent, if CMSI or CitiMortgage delivers

103

an opinion of counsel acceptable to the Trustee and the Insurer to the effect that the amendment will not materially adversely affect the interests of the certificate holders or the Insurer.

The Trustee will execute and deliver any amendment to this agreement provided by CMSI or CitiMortgage that conforms to the preceding two paragraphs, but the Trustee need not enter into any such amendment that affects the Trustee’s own rights, duties or immunities under this agreement or otherwise.

This Agreement may also be amended by the parties to add, change or eliminate provisions of this agreement, or to modify the rights of certificate holders; with the consent of

1 the holders of 2/3 of the certificates,

2 if a class of certificates is affected materially and adversely by the amendment in a way that is different from the other affected classes, 2/3 of the certificates of the differently affected class, and

3 the Insurer if the Insurer is materially and adversely affected by the amendment.

Approval shall be by percentage interest for residual certificates and by principal balance for all other certificates.

In connection with any such amendment, CMSI or CitiMortgage will deliver an opinion of counsel acceptable to the Trustee (x) identifying any class of certificates that may be affected materially and adversely by the amendment in a way that is different from the other affected classes (or stating that there is no such differently affected class) and (y) identifying any class whose certificate holders would not be materially adversely affected by such amendment.

Notwithstanding the foregoing, no amendment will, without the consent of the holders of all the outstanding certificates

· reduce or delay collections or payments received on mortgage loans or distributions to be made on any certificate, or

· reduce the proportion required to consent to any such amendment.

Certificate holders may consent to an amendment by approving the substance of the amendment rather than the particular form of the proposed amendment. The Trustee may prescribe reasonable requirements for the manner of obtaining and evidencing such consents. Any proposed amendment is subject to the receipt by the Trustee of a legal opinion, at the expense of the party proposing the amendment (or at the expense of the Trust Fund if proposed by the Trustee), that the amendment will not cause any constituent REMIC to fail to qualify as a REMIC or subject any constituent REMIC to tax.

Promptly after the execution of any such amendment or such consent, the Trustee will notify each certificate holder of the substance of the amendment or provide the holder with a copy of the amendment.

10.2 Recordation of Agreement

Any manually signed copy of this agreement may be recorded in any appropriate public office for real property records in a county or other jurisdiction where mortgaged properties are located, or any other appropriate public recording office. CitiMortgage will effect such recordation at its expense upon the Trustee’s request, acting at the direction of the holders of a majority by percentage interest of the residual certificates. The request must be accompanied by a legal opinion to the effect that the recording will materially and beneficially affect the interests of the certificate holders.

104

10.3 Limitation on rights of certificate holders

A certificate holder’s death or incapacity will not terminate this agreement or the Trust Fund, nor entitle the certificate holder’s legal representatives or heirs to claim an accounting or to take an action or commence a proceeding in any court for a partition or winding up of the Trust Fund, nor otherwise affect the rights, obligations and liabilities of any party to this agreement.

No certificate holder may vote (except as provided in section 10.1) or otherwise control the operation and management of the Trust Fund or the obligations of the parties, nor will anything in this agreement or the certificates be construed to constitute the certificate holders as partners (except to the extent provided in Internal Revenue Code Section 860F(e) for holders of residual certificates) or members of an association; nor will a certificate holder be liable to any third person for any action taken by the parties to this agreement pursuant to its provisions.

A certificate holder may not institute any suit, action or proceeding with respect to this agreement, unless

· the holder has notified the Trustee of the continuance of an Event of Default,

· the holders of the Required Amount of certificates have requested the Trustee to institute such action, suit or proceeding in its own name as Trustee, and have offered the Trustee such reasonable indemnity as it requires against the costs, expenses and liabilities to be incurred, and

· the Trustee, for 60 days after its receipt of the notice, request and offer of indemnity, fails to institute any the action, suit or proceeding.

Each certificate holder understands, and agrees with every other certificate holder and the Trustee, that no certificate holders may under this agreement affect, disturb or prejudice the rights of any other certificate holders, or obtain priority over or preference to any such other holders, or enforce any right under this agreement, except as provided in this agreement, and for the equal, ratable and common benefit of all certificate holders. For the protection and enforcement of the provisions of this section 10.3, each certificate holder and the Trustee may seek such relief as can be given either at law or in equity.

10.4 Governing law

This Agreement and the certificates will be governed by the laws of the State of New York, except that the immunities and standards of care of the Trustee will be governed by the law of the jurisdiction in which its corporate trust office is located.

10.5 Maintenance of REMICs

The execution and delivery of this agreement will constitute an acknowledgment by each of CMSI and CitiMortgage on behalf of the certificate holders that it intends hereby to establish and maintain (for federal income tax purposes) one or more “real estate mortgage investment conduits” within the meaning of Internal Revenue Code Section 860D, and CMSI and CitiMortgage are hereby granted all necessary powers to further such intent.

10.6 Notices

Except as otherwise stated in this agreement, all communications relating to this agreement including all demands and notices will be in writing and will be deemed to have been duly given if personally delivered at or mailed by first class mail, to a party at the address for notices set forth in the Series Terms or at such other address as the party designates

105

in a written notice to each other party. Any notice required or permitted to be mailed to a certificate holder will be given by first class mail, postage prepaid, at the holder’s address shown in the Certificate Register. Any notice so mailed within the time prescribed in this agreement will be conclusively presumed to have been duly given, whether or not the certificate holder receives the notice. Notices to the Trustee will be effective only upon receipt.

10.7 Severability of provisions

If a provision of this agreement is held invalid, then such provisions will be deemed severable from the remaining provisions of this agreement and will in no way affect the validity or enforceability of the other provisions, or of the certificates or the rights of their holders.

10.8 Assignment

Notwithstanding anything to the contrary in this agreement, except as provided in sections 4.2, 4.3 and 4.5, CMSI or CitiMortgage may not assign this agreement without the prior consent of the Trustee and the holders of 2/3 of the outstanding certificates and 2/3 of the percentage interests of the outstanding residual certificates.

10.9 Certificates nonassessable and fully paid

It is the intention of the Trustee that the certificate holders will not be personally liable for obligations of the Trust Fund, that the interests represented by the certificates will be nonassessable for any losses or expenses of the Trust Fund or for any reason whatsoever, and that the certificates upon authentication thereof by the Trustee pursuant to section 2.5 are and will be deemed fully paid.

11 Depositories

11.1 Depositories

CitiMortgage may transfer the certificate account, buydown account, if any, escrow account, custodial accounts for P&I or servicing account to a bank, savings and loan association or trust company organized under the laws of the United States or any State thereof (an “eligible depository”). Upon such transfer, such transferee bank, savings and loan association or trust company will be deemed to be a Depository for the transferred account or accounts.

For a Depository of the certificate account, buydown account, escrow account, custodial accounts for P&I or servicing account to satisfy the “rating requirement”

· its long-term debt obligations must be rated at least “A” by Fitch if Fitch is a rating agency, and

· its short-term debt obligations are rated at least “A-1+” by S&P if S&P is a rating agency, “F-1” by Fitch if Fitch is a rating agency, and “P-1” by Moody’s if ▇▇▇▇▇’▇ is a rating agency.

If a Depository ceases to satisfy the rating requirement, then within five business days after such cessation, CitiMortgage will

(A) transfer or direct the Trustee to transfer the certificate account, buydown account, escrow account, custodial accounts for P&I or servicing account to an eligible depository that satisfies the rating requirements,

(B) establish another account in the corporate trust department of the Trustee or if such Trustee satisfies the rating requirements, in any department of the Trustee (the “alternative certificate account,” “alternative buydown account,” “alternative escrow account,” “alternative custodial accounts for P&I,” or “alternative servicing account,” as the case may be) and transfer the funds from the buydown

106

account to the alternative buydown account, direct CitiMortgage or a third-party servicer, as applicable, to remit in accordance with this agreement any funds deposited into the servicing account, escrow account or custodial accounts for P&I to the alternative servicing account, alternative escrow account or alternative custodial account for P&I, respectively, and direct CitiMortgage to remit in accordance with this agreement any funds deposited into the certificate account to the alternative certificate account,

(C) (i) cause the Depository to pledge securities in the manner provided by applicable law or (ii) pledge or cause to be pledged securities, which will be held by the Trustee or its agent free and clear of the lien of any third party, in a manner conferring on the Trustee a perfected first lien and otherwise reasonably satisfactory to the Trustee; such pledge in either case to secure the Depository’s performance of its obligations in respect of the certificate account, buydown account, escrow account, custodial accounts for P&I or servicing account to the extent, if any, that such obligation is not fully insured by the FDIC; provided, however, that prior to the day a Depository or CitiMortgage, as the case may be, pledges securities pursuant to this subsection (C), CitiMortgage, any Insurer and the Trustee have received the written assurance of each rating agency that the pledging of such securities and any arrangements or agreements relating thereto will not result in a reduction or withdrawal of the then-current rating of the certificates (for any insured class certificates, without reference to any certificate insurance policy),

(D) establish an account or accounts or enter into an agreement so that the existing certificate account, buydown account, escrow account, custodial accounts for P&I or servicing account is supported by a letter of credit or some other form of credit support, which issuer of such letter of credit or other form of credit support has a long-term and short-term debt rating at least equal to the rating requirements; provided, however, that prior to the establishment of such an account or the entering into of such an agreement, CitiMortgage, any Insurer and the Trustee receive written assurance from each rating agency that the establishment of such an account or the entering into of such an agreement so that the existing certificate account, buydown account or servicing account is supported by a letter of credit or some other form of credit support will not result in a reduction or withdrawal of the then-current rating on the certificates (for an insured class certificates, without reference to a certificate insurance policy),

(E) establish another account which constitutes an Eligible Account, or

(F) make such other arrangements as to which CitiMortgage, any Insurer and the Trustee have received prior written assurance from each rating agency that such arrangement will not result in a reduction or withdrawal of the then-current rating on the certificates.

If the rating on the certificates has been downgraded as a result of a rating downgrade of the Depository, for purposes of this paragraph, the then-current rating on the certificates will be the rating assigned to the certificates prior to any such downgrade (for any insured class certificates, without reference to any certificate insurance policy).

(4) establish any other arrangement approved by the Counterparty, such approval not to be unreasonably withheld, which will be sufficient to restore the immediately prior ratings of their Certificates.
