c) Each Advance made under a Prime Credit Line will be a Variable Advance.

d) Unless otherwise agreed by the Bank: (i) all Fixed Rate Advances must be in an amount of at least $100,000; and (ii) all Variable Rate Advances taken by wire transfer must be in an amount of at least $2,500. If the Borrower is a natural person, the initial Variable Rate Advance under the Credit Line must be in an amount equal to at least $25,001 (the “Initial Advance Requirement”). If the Initial Advance requested by the Borrower is made in the form of a check drawn on the Credit Line that does not satisfy the Initial Advance Requirement, then, in addition to and not in limitation of the Bank’s rights, remedies, powers or privileges under this Agreement or applicable law, the Bank may, in its sole and absolute discretion:

(i) pay the check drawn by the Borrower if, prior to paying that check, the Bank makes another Advance to the Borrower, which Advance shall be in an amount not less than $25,001; or

(ii) pay the check drawn by the Borrower; or

(iii) decline to pay (bounce) the check.

If the Bank elects option (ii), no interest shall accrue on the amount of the Advance made by paying the check, and the amount of that Advance shall be due and payable to the Bank immediately (with or without demand by the Bank).

4) Interest

a) Each Fixed Rate Advance will bear interest at a fixed rate and for the Interest Period each as specified in the related Advance Advice. The rate of interest payable on each Fixed Rate Advance will be determined by adding a percentage rate to the UBS Bank USA Fixed Funding Rate, as of the date that the fixed rate is determined.

b) Each Variable Rate Advance under a Premier Credit Line will bear interest at a variable rate equal to LIBOR, adjusted daily, plus the percentage rate that (unless otherwise specified by the Bank in writing) is shown on Schedule I below for the Approved Amount of the Credit Line. For Premier Credit Lines, the rate of interest payable on Variable Rate Advances is subject to change without notice in accordance with fluctuations in LIBOR and in the Approved Amount. On each day that LIBOR changes or the Approved Amount crosses one of the thresholds that is indicated on Schedule I (or that is otherwise specified by the Bank in writing), the interest rate on all Variable Rate Advances will change accordingly.

c) Each Variable Rate Advance under a Prime Credit Line will bear interest at a variable rate equal to the Prime Rate, adjusted daily, plus the percentage rate that (unless otherwise specified by the Bank in writing) is shown on the attached Schedule II and that corresponds to the aggregate principal amount outstanding under the Prime Credit Line on that day. For Prime Credit Lines, the rate of interest payable on Variable Rate Advances is subject to change without notice in accordance with fluctuations in the Prime Rate and in the aggregate amount outstanding under the Prime Credit Line. On each date that the Prime Rate changes or the aggregate principal amount outstanding under the Prime Credit Line crosses one of the thresholds that is indicated on Schedule II (or that is otherwise specified by the Bank in writing), the interest rate on all Variable Rate Advances will change accordingly.

5) Payments

a) Each Fixed Rate Advance will be due and payable in full ON DEMAND or, if not earlier demanded by the Bank, on the last day of the applicable Interest Period. Any Fixed Rate Advance as to which the Bank has not made a demand for payment and that is not paid in full or renewed, which renewal is in the sole and absolute discretion of the Bank, (pursuant to procedures as may be established by the Bank) as another Fixed Rate Advance on or before the last day of its Interest Period, will be automatically renewed on that date as a U.S. dollar denominated, Variable Rate Advance in an amount (based, in the case of any conversion of a non-US. dollar denominated Fixed Rate Advance, upon the applicable, spot currency exchange rate as of the maturity date, as determined by the Bank) equal to the unpaid principal balance of the Fixed Rate Advance plus any accrued but unpaid interest on the Fixed Rate Advance, which Variable Rate Advance will then accrue additional interest at a variable rate as provided in this Agreement.

b) Each Variable Rate Advance will be due and payable ON DEMAND.

c) The Borrower promises to pay the outstanding principal amount of each Advance, together with all accrued but unpaid interest on each Advance, any and all fees or other charges payable in connection with each Advance, on the date the principal amount becomes due (whether by reason of demand, the occurrence of a stated maturity date, by reason of acceleration or otherwise). The Borrower further promises to pay interest in respect of the unpaid principal balance of each Advance from the date the Advance is made until it is paid in full. All interest will be computed on the basis of the number of days elapsed and a 360-day year. Interest on each Advance will be payable in arrears as follows:

(i) for Fixed Rate Advances - on the last day of the Interest Period (or if the Interest Period is longer than three months, on the last day of each three month period following the date of the Advance) and on each date that all or any portion of the principal amount of the Fixed Rate Advance becomes due or is paid; and

(ii) for Variable Rate Advances - on the twenty-second day of each month other than December, and on the thirty-first day of December, and on each date that all or any portion of the principal amount of the Variable Rate Advance becomes due or is paid.

To the extent permitted by law, and without limiting any of the Bank’s other rights and remedies under the Agreement, interest charges on any Advance that are not paid when due will be treated as principal and will accrue interest at a variable rate from the date the payment of interest was due until it is repaid in full.

d) All payments of principal, interest or other amounts payable under this Agreement will be made in immediately available funds and in the same currency in which the Advance was made, which unless otherwise agreed by the Bank, will be U.S. dollars. UBS Financial Services Inc. or UBS International Inc., as applicable, may act as collecting and servicing agent for the Bank for the Advances. All payments will be made by wire transfer of funds to an account specified by the Bank or by another method agreed upon by the Bank and the Borrower. Upon receipt of all payments, the Bank will credit the same to the Credit Line Account. The Bank shall apply the proceeds of any payments in the following order; first to any Breakage Costs, Breakage Fee, other fees, costs of collection and expenses, second to the outstanding principal amount of the related Advance and third to accrued interest.

e) All payments must be made to the Bank free and clear of any and all present and future taxes (including withholding taxes), levies, imposts, duties, deductions, fees, liabilities and similar charges other than those imposed on the overall net income of the Bank. If so requested by the Bank, the Borrower will deliver to the Bank the original or a certified copy of each receipt evidencing payment of any taxes or, if no taxes are payable in respect of any payment

under this Agreement, a certificate from each appropriate taxing authority, or an opinion of counsel in form and substance and from counsel acceptable to the Bank in its sole and absolute discretion, in either case stating that the payment is exempt from or not subject to taxes. If any taxes or other charges are required to be withheld or deducted from any amount payable by the Borrower under this Agreement, the amount payable will be increased to the amount which, after deduction from the increased amount of all taxes and other charges required to be withheld or deducted from the amount payable, will yield to the Bank the amount stated to be payable under this Agreement. If any of the taxes or charges are paid by the Bank, the Borrower will reimburse the Bank on demand for the payments, together with all interest and penalties that may be imposed by any governmental agency. None of the Bank, UBS Financial Services Inc., UBS-I or their respective employees has provided or will provide legal advice to the Borrower or any Loan Party regarding compliance with (or the implications of the Credit Line and the related guaranties and pledges under) the laws (including tax laws) of the jurisdiction of the Borrower or any Loan Party or any other jurisdiction. The Borrower and each Loan Party are and shall be solely responsible for, and the Bank shall have no responsibility for, the compliance by the Loan Parties with any and all reporting and other requirements arising under any applicable laws.

f) In no event will the total interest and fees, if any, charged under this Agreement exceed the maximum interest rate or total fees permitted bylaw. In the event any excess interest or fees are collected, the same will be refunded or credited to the Borrower. If the amount of interest payable by the Borrower for any period is reduced pursuant to this Section 5(f), the amount of interest payable for each succeeding period will be increased to the maximum rate permitted by law until the amount of the reduction has been received by the Bank.

6) Prepayments; Breakage Charges

a) The Borrower may repay any Variable Rate Advance at any time, in whole or in part, without penalty.

b) The Borrower may repay any Fixed Rate Advance, in whole or in part. The Borrower agrees to reimburse the Bank, immediately upon demand, for any loss or cost (“Breakage Costs”) that the Bank notifies the Borrower has been incurred by the Bank as a result of (i) any payment of the principal of a Fixed Rate Advance before the expiration of the Interest Period for the Fixed Rate Advance (whether voluntarily, as a result of acceleration, demand or otherwise), or (ii) the Customer’s failure to take any Fixed Rate Advance on the date agreed upon, including any loss or cost (including loss of profit or margin) connected with the Bank’s re-employment of the amount so prepaid or of those funds acquired by the Bank to fund the Advance not taken on the agreed upon date.

Breakage Costs will be calculated by determining the differential between the stated rate of interest (as determined in accordance with Section 4(a) of the Agreement) for the Fixed Rate Advance and prevailing LIBOR and multiplying the differential by the sum of the outstanding principal amount of the Fixed Rate Advance (or the principal amount of Fixed Rate Advance not taken by the Borrower) multiplied by the actual number of days remaining in the Interest Period for the Fixed Rate Advance (based upon a 360-day year). The Borrower also agrees to promptly pay to the Bank an administrative fee (“Breakage Fee”) in connection with any permitted or required prepayment. The Breakage Fee will be calculated by multiplying the outstanding principal amount of the Fixed Rate Advance (or the principal amount of Fixed Rate Advance not taken by the Borrower) by two basis points (0.02%) (with a minimum Breakage Fee of $100.00). Any written notice from the Bank as to the amount of the loss or cost will be conclusive absent manifest error.

7) Joint Credit Line Account Agreement; Suspension and Cancellation

a) If more than one Person is signing this Agreement as the “Borrower”, each party (a “Joint Borrower”) will be jointly and severally liable for the Credit Line Obligations, regardless of any change in business relations, divorce, legal separation, or other legal proceedings or in any agreement that may affect liabilities between the parties. Except as provided below for the reinstatement of a suspended or cancelled Credit Line, and unless otherwise agreed by the Bank in writing, the Bank may rely on, and each joint Borrower will be responsible for, requests for Advances, directions, instructions and other information provided to the Bank by any joint Borrower.

b) Any Joint Borrower may request the Bank to suspend or cancel the Credit Line by sending the Bank a written notice of the request addressed to the Bank at the address shown on the Borrower’s periodic Credit Line Account statements. Any notice will become effective three Business Days after the date that the Bank receives it, and each Joint Borrower will continue to be responsible for paying: (i) the Credit Line Obligations as of the effective date of the notice, and (ii) all Advances that any Joint Borrower has requested but that have not yet become part of the Credit Line Obligations as of the effective date of the notice. No notice will release or in any other way affect the Bank’s interest in the Collateral. All subsequent requests to reinstate credit privileges must be signed by all Joint Borrowers comprising the Borrower, including the Joint Borrower requesting the suspension of credit privileges. Any reinstatement will be granted or denied in the sole and absolute discretion of the Bank.

c) All Credit Line Obligations will become immediately due and payable in full as of the effective date of any suspension or cancellation of the Credit Line. The borrower will be responsible for the payment of all charges incurred on the Advances after the effective date.

the signature of the Borrower and any Pledgor where permitted by applicable law) financing statements and amendments thereto, control agreements, notices, assignments, listings, powers, consents and other documents regarding the Collateral and the Bank’s security interest in the Collateral in such jurisdiction and in a form as the Bank reasonably may require. Each Loan Party irrevocably authorizes and appoints each of the Bank and UBS Financial Services Inc., as collateral agent, to act as their agent and attorney-in-fact to file any documents or to execute any .documents in their name, with or without designation of authority Each Loan Party acknowledges that it will be obligated in respect of the documentation as if it had executed the documentation itself.

c) The Borrower (and, if applicable, any other Pledgor on the Collateral Account) agrees to maintain in a Collateral Account, at all times, Collateral having an aggregate lending value as specified by the Bank from time to time.

d) The Bank’s sole duty for the custody, safe keeping and physical preservation of any Collateral in its possession will be to deal with the Collateral in the same manner as the Bank deals with similar property for its own account. The Borrower (and, if applicable, any other Pledgor on the Collateral Account) agrees that the Bank will have no responsibility to act on any notice of corporate actions or events provided to holders of securities or other investment property included in the Collateral. The Borrower (and, if applicable, any other Pledgor on the Collateral Account) agrees to (i) notify the Bank promptly upon receipt of any communication to holders of the investment property disclosing or proposing any stock split, stock dividend, extraordinary cash dividend, spin-off or other corporate action or event as a result of which the Borrower or Pledgor would receive securities, cash (other than ordinary cash dividends) or other assets in respect of the investment property, and (ii) immediately upon receipt by the Borrower or Pledgor of any of these assets, cause them to be credited to a Collateral Account or deliver them to or as directed by the Bank as additional Collateral.

e) The Borrower (and, if applicable, any other Pledgor on the Collateral Account) agrees that all principal, interest, dividends, distributions, premiums or other income and other payments received by the Bank or credited to the Collateral Account in respect of any Collateral may be held by the Bank as additional Collateral or applied by the Bank to the Credit Line Obligations. The Bank may create a security interest in any of the Collateral and may, at any time and at its option, transfer any securities or other investment property constituting Collateral to a securities account maintained in its name or cause any Collateral Account to be redesignated or renamed in the name of the Bank.

f) The Borrower (and, if applicable, any other Pledgor on the Collateral Account) agrees that if a Collateral Account has margin features, the margin features will be removed by UBS Financial Services Inc. or UBS International Inc., as applicable, so long as there is no outstanding margin debit in the Collateral Account.

g) If the Collateral Account permits cash withdrawals in the form of check writing, access card charges, bill payment and/ or electronic funds transfer services (for example, Resource Management Account®, Business Services Account BSA®, certain Basic Investment Accounts and certain accounts enrolled in UBS Financial Services Inc. Investment Consulting Services programs), the Borrower (and, if applicable, any other Pledgor on the Collateral Account) agrees that the “Withdrawal Limit” for the Collateral Account, as described in the documentation governing the account will be reduced on an ongoing basis so that the aggregate lending value of the Collateral remaining in the Collateral Account following the withdrawal may not be less than the amount required pursuant to Section 8(c),

h) In addition to the Bank’s security interest, the Borrower (and, if applicable, any other Pledgor on the Collateral Account) agrees that the Bank will at all times have a right to set off any or all of the Credit Line Obligations at or after the time at which they become due, whether upon demand, at a stated maturity date, by acceleration or otherwise, against all securities, cash, deposits or other property in the possession of or at any time in any account maintained with the Bank or any of its affiliates by or for the benefit of the Borrower, whether carried individually or jointly with others. This right is in addition to, and not in limitation of, any right the Bank may have at law or otherwise.

i) The Bank reserves the right to disapprove any Collateral and to require the Borrower at any time to deposit into the Borrower’s Collateral Account additional Collateral in the amount as the Bank requests or to substitute new or additional Collateral for any Collateral that has previously been deposited in the Collateral Account.

9) Control

For the purpose of giving the Bank control over each Collateral Account and in order to perfect the Bank’s security interests in the Collateral, the Borrower and each Pledgor on the applicable Collateral Account consents to compliance by UBS Financial Services inc., UBS-I or any other securities intermediary (in any case, the “Securities Intermediary”) maintaining a Collateral Account with entitlement orders and instructions from the Bank (or from any assignee or successor of the Bank) regarding the Collateral Account and any financial assets or other property held therein without the further consent of the Borrower or any other Pledgor on the applicable Collateral Account. Without limiting the foregoing, the Borrower and each Pledgor on the Collateral Account acknowledges, consents and agrees that, pursuant to a control agreement entered into between the Bank and the Securities Intermediary:

a) The Securities Intermediary will comply with entitlement orders originated by the Bank regarding any Collateral Account without further consent from the Borrower or any Pledgor. The Securities Intermediary will treat all assets credited to a Collateral Account, including money and credit balances, as financial assets for purposes of Article 8 of the Uniform Commercial Code.

b) In order to enable the Borrower and any Pledgor on the applicable Collateral Account to trade financial assets that are from time to time credited to a Collateral Account, the Securities Intermediary may comply with entitlement orders originated by the Borrower or any Pledgor on the applicable Collateral Account (or if so agreed by the Bank, by an investment adviser designated by the Borrower or any Pledgor on the applicable Collateral Account and acceptable to the Bank and the Securities Intermediary) regarding the Collateral Account, but only until the time that the Bank notifies the Securities Intermediary, that the Bank is asserting exclusive control over the Collateral Account. After the Securities Intermediary has received a notice of exclusive control and has had a reasonable opportunity to comply, it will no longer comply with entitlement orders originated by the Borrower or any Pledgor (or by any investment adviser designated by the Borrower or any Pledgor) concerning the Collateral Account, Notwithstanding the foregoing, however, and irrespective of whether it has received any notice of exclusive control, the Securities intermediary will not comply with any entitlement order originated by the Borrower or any Pledgor (or by any investment adviser designated by the Borrower or any Pledgor) to withdrawal financial assets from a Collateral Account or to pay any money, free credit balance or other amount owing on a Collateral Account (other than cash withdrawals and payments not exceeding the “Withdrawal Limit” as contemplated in Section 8 (g)) without the prior consent of the Bank.

Upon such automatic assignment and subrogation, UBS Financial Services Inc. and any such third party shall be entitled to directly exercise any and all rights and remedies afforded the Bank under the Agreement, this Addendum and any and all other documents and agreements entered into in connection with the Agreement and/or this Addendum.”

Interest

3. The Agreement is amended by adding the following as a new Section 4 d), Section 4 e) and Section 4 f):

“d) Notwithstanding anything to the contrary in this Agreement, and subject to the provisions of Sections 4 e) and f) of this Agreement, the interest rate charged on any and all outstanding Variable Rate Advances shall be the lesser of (i) the amount prescribed by Sections 4 a), b), or c) of this Agreement, as applicable, and (ii) the then applicable weighted average rate of interest or dividend rate paid to the Borrower by the issuer of the ARS Collateral.

e) The Bank and the Borrower acknowledge and agree that the Bank shall be entitled to determine or adjust, at any time and from time to time, the interest rate payable by the Borrower to the Bank on all or any part of the outstanding Variable Rate Advances to reflect any changes in the composition of the ARS Collateral, to address any inability to determine interest rates, or for any other reason that, in the Bank’s sole and absolute discretion, is necessary to give effect to the intent of the provisions of this Agreement, including, without limitation, this Section 4 (it being acknowledged and agreed that the provisions of this Section 4 are intended to cause the interest payable by the Borrower under this Agreement to equal the interest or dividend rate payable to the Borrower by the issuer of any ARS Collateral) and any and all such adjustments by the Bank hereunder shall be conclusive and binding on the Bank and The Borrower absent manifest error.

f) if and to the extent that any or all of the ARS Collateral consists of Taxable Student Loan Auction Rate Securities, then notwithstanding anything to the contrary in this Agreement, when calculating such weighted average interest rate, the interest rate paid to the Borrower with respect to such Taxable Student Loan Auction Rate Securities shall be deemed to be equal to (i) for the period from the date of this Addendum through and including January 21, 2009, the applicable coupon rate(s) and (ii) from January 22, 2009 and thereafter, the then applicable Taxable SLARC Maximum Auction Rate, for, and to the extent of, such Taxable Student Loan Auction Rate Securities, The Borrower will be charged interest on the Loan in months in which the Borrower does not receive interest on the Taxable Student Loan Auction Rate Securities.”

Payments

4. The Agreement is amended by adding the following as Section 5 g):

“The Borrower will make additional payments (“Additional Payments”) as follows:

• The proceeds of any liquidation, redemption, sale or other disposition of all or part of the ARS Collateral will be automatically transferred to the Bank as payments. The amount of these payments will be determined by the proceeds received in the Collateral Account, and may be as much as the total Credit Line Obligations,

• All other interest, dividends, distributions, premiums, other income and payments that are received in the Collateral Account in respect of any ARS Collateral will be automatically transferred to the Bank as payments. These are referred to as “ARS Payments.” The amount of each ARS Payment will vary, based on the proceeds received in the Collateral Account. The Bank estimates that the ARS Payments will range from zero to fifteen ($ 15 .00) dollars per month per $ 1.000 in par value of Pledged ARS. The Bank will notify the Borrower at least ten (10) days in advance of any ARS Payment that falls outside of this range. If the Borrower would prefer to have advance notice of each payment to be made to Advances, the Borrower may cancel ARS Payments as described below.

• The Borrower agrees that any cash, check or other deposit (other than a deposit of securities) made to the Collateral Account is an individual authorization to have such amount transferred to the Bank as a payment. The amount of each payment is the amount of the deposit.

Each Additional Payment will be applied, as of the date received by the Bank, in the manner set forth in the last sentence of Section 5 d). The Borrower acknowledges that neither the Bank nor UBS financial Services Inc. sets or arranges for any schedule of Additional Payments. Instead, Additional Payments will be transferred automatically from the Collateral Account whenever amounts are received in the Collateral Account, generally on the second Business Day after receipt.

The Borrower may elect to stop ARS Payments at any time, and this election will cancel all ARS Payments that would occur three (3) Business Days or more after the Bank receives such notice. If the Borrower stops ARS Payments, the Borrower will continue to be obligated to pay principal, interest, and other amounts pursuant to the Agreement. If the Borrower elects to cancel ARS Payments, all other Additional Payments will be cancelled. Cancelling ARS Payments and Additional Payments may result in higher interest charges by the Bank because amounts received in the Collateral Account will not be automatically transferred and credited. Any amounts received in the Collateral Account will remain in the Collateral Account unless the Bank permits you to withdraw all or part of such amounts. Your notice to cancel must be sent to; Attention: Head of Credit Risk Monitoring, UBS Bank USA, 000 Xxxxx Xxxx Xxxxxx. Suite 2275. Salt Lake City, Utah 84111. or call (000) 000-0000.

Important Disclosure About Required Payments. If Additional Payments are sufficient to pay all accrued interest on Advances on or before a due date, then the Borrower need not make an additional interest payment. Excess Additional Payments will be applied against principal. However, if Additional Payments are not sufficient to pay all accrued interest on Advances on or before a due date, then the Bank may, in its sole discretion (1) capitalize unpaid interest as an additional Advance, or (2) require the Borrower to make payment of all accrued and unpaid interest.”

Remedies

5. The Agreement is amended by adding the following as Section 10 e):

The Borrower acknowledges that the price the Bank obtains for Collateral in the Bank’s chosen method of safe may be lower than might be otherwise obtained in another method of sale, and the Borrower hereby agrees that any such sale shall not be considered to be not commercially reasonable solely because of such lower price. The Borrower understands that there may not be a liquid market for the Collateral and that, as a result, the price received for the Collateral upon liquidation or sale by the Bank may be substantially less than the Borrower paid for such Collateral or than the last market value available for it, if any The Borrower further agrees that any sale by the Bank shall not be considered to be not commercially reasonable solely because there are few (including only one) or no third parties who submit bids or otherwise offer to buy the Collateral, The Borrower understands that the Bank’s sale of any of the Collateral may be subject to various stale and federal property and/or securities laws and regulations, and that compliance with such laws and regulations may result in delays and/or a lower price being obtained for the Collateral. The Borrower agrees that the Bank shall have the right to restrict any prospective purchasers to those who, in the Bank’s sole discretion, the Bank deems to be qualified. The Borrower acknowledges that the Bank shall have sole authority to determine, without limitation, the time, place, method of advertisement and manner of sale and that the Bank may delay or adjourn any such sale in its sole discretion. The Borrower expressly authorizes the Bank to take any action with respect to the Collateral as the Bank deems necessary or advisable to facilitate any liquidation or sale, and the Borrower agrees that the Bank shall not be held liable for taking or failing to lake any such action, regardless if a greater price may have been obtained for the Collateral if such action was or was not taken as applicable. The Borrower hereby waives, to the fullest extent permitted by law, any legal right of appraisal, notice, valuation, stay, extension, moratorium or redemption that the Borrower would otherwise have with respect to a sale of the Collateral.”

Representations, Warranties and Covenants by the Loan Parties

6. The Agreement is amended by adding the following as Section 11 g):

The Borrower hereby acknowledges and agrees with the Bank and directs UBS Financial Services Inc. that to the extent permitted by applicable law, this Section 11 g) shall constitute an irrevocable instruction, direction and standing sell order to UBS Financial Services Inc. to effect, an ARS Liquidation to the extent it is possible to do so at anytime during the term of this Agreement.

IMPORTANT NOTICE ON INTEREST RATES AND PAYMENTS

Credit Line Account				Account Number
Cepheid
Collateral Account				Account Number
Cepheid

This document contains important information regarding the interest rate and interest payments on your Credit Line. You should carefully review this Notice and your Credit Line Application and Agreement including the Addendum, (the “Agreement”) and speak to your Financial Advisor regarding any questions or concerns you may have with your Agreement. Defined terms used in this Notice have the respective meanings set forth in the Agreement unless defined in this Notice.

The Agreement provides you with a “no net cost” Credit Line. This means that the interest that you pay on the Credit Line Obligations will not exceed the interest that you receive on the Auction Rate Securities that you have pledged to the Bank as security for the Credit Line and which are held in the Collateral Account. Although you may be able to capitalize interest you will not be charged interest on interest.

The Credit Line statements that you receive from the Bank while the Credit Line is outstanding are for information purposes only. The interest charge(s) on these statements are approximations due to timing and systems limitations. You will receive a final confirmation from the Bank of the interest charged on the Credit Line. This does not change the “no net cost” nature of the Credit Line.

If you have Taxable Student Loan Auction Rate Securities pledged as Collateral you may not receive an interest payment in months in which you are charged interest on the Credit Line. Certain taxable student loan ARS made high interest rate payments to UBSFS investors for several months during the first half of 2008, and then ceased making interest payments in subsequent months. These taxable student loan ARS will not make any further interest payments until a future date determined in accordance with the terms of the Auction Rate Securities. For the purpose of determining loan interest payments for loans against these Taxable Student Loan Auction Rate Securities, the high interest payments will be taken into consideration (and the interest rate annualized). For example, you will be charged (i) for the period from the date of the Addendum through and including January 21, 2009, the applicable coupon rate(s) on the Taxable Student Loan Auction Rate Securities and (ii) from January 22, 2009 and thereafter you will be charged that average annualized rate (e.g. T-bills plus 120 basis points). For each month in which your loan is outstanding, including months for which the annualized interest was paid in a prior month and for which no additional or current payment is being made to you.

Interest on the Credit Line accrues daily and is charged in accordance with the Bank’s regular interest billing cycle. The Bank’s billing cycle may not be the same as the cycle on which the Auction Rate Securities pay interest.

Please acknowledge your receipt and review of this Notice by signing below.
