2.3 Contribution Value; Debt Assumption.

The value of each of the Properties and the R&B Property to be contributed to the ASOT Acquiring Party pursuant to this Agreement is identified on Schedule 2.1 attached hereto (each value so identified is hereinafter the “Contribution Value”); provided, however, the Contribution Value of the Property described in Schedule 2.1 as the San Xxxx South Property (i) is subject to a reduction of $2,000,000 in the event that ASOT reasonably determines that the San Xxxx South Property does not have the entitlements described in Schedule 2.3(a) attached hereto and (ii) shall be increased by an amount equal to the excess, if any, of $11,835,000 over the first year capital needs of the Improvements on the San Xxxx South Property as reasonably determined by ASOT (after consultation with a third party consultant in connection with a physical condition report) prior to the conclusion of the Due Diligence Period.

(b) Assumed Debt; Debt Repayment.

(i) Subject to obtaining the applicable lender’s consent in accordance with Sections 8.2(a) or (b) hereof, as applicable, upon the contribution of any Property encumbered with Assumed Debt (other than any Assumed Debt which ASOT elects in its sole discretion to prepay or defease at ASOT’s sole cost and expense after the applicable Closing but such election will not convert such Assumed Debt to Subject to Debt), the ASOT Acquiring Party shall assume the obligations of the Assumed Debt accruing thereon or arising from and after the applicable Closing (including the obligation to repay the then outstanding principal amount of the Assumed Debt and all accrued and unpaid

interest thereon). Upon the contribution of any Property encumbered with Subject to Debt, the ASOT Acquiring Party shall acquire the Property subject to the Subject to Debt or, in ASOT’s sole discretion and at ASOT’s sole cost and expense, including assumption fees (unless (i) the applicable lender requires such assumption as a condition to permitting the transfer to the ASOT Acquiring Party notwithstanding that the ASOT Acquiring Party may immediately thereafter pay it off, and (ii) the applicable Property Partnership or Property Partnerships determine in their sole discretion that an assumption is required, in which case the assumption shall be at such Property Partnership’s or Property Partnerships’ sole cost and expense), elect to assume the obligations accruing or arising from and after Closing of the Subject to Debt (including the obligation to repay the then outstanding principal amount of the Assumed Debt and all accrued and unpaid interest thereon). In connection with the contribution of any Property with respect to which there are Other Liabilities, the ASOT Acquiring Party shall assume the obligations of such Other Liability (including the obligation to repay the then outstanding principal amount of the Other Liabilities and all accrued and unpaid interest thereon). However, subject to the terms of the applicable Tax Agreement, at any time following the contribution of any Property encumbered with Assumed Debt (other than “locked” Assumed Debt), Subject to Debt and/or Other Liabilities, including on the applicable Closing Date but only after the contribution has taken place, the ASOT Acquiring Party may, in its sole and absolute discretion and at its sole cost and expense (except as provided in Section 2.3(b)(ii) below) prepay and fully discharge or defease any such debt or liabilities.

(ii) The Contribution Value of each of the Assumed Debt Properties shall be reduced by the amount set forth on the applicable Loan Amount Statement with respect to the Assumed Debt Properties, other than by the amount of any prepayment fees, penalties or premiums, any defeasance costs and any and all other fees, costs and expenses which ASOT will pay in cash in accordance with the following sentence, reflected on such Loan Amount Statement, all of which will be the responsibility of ASOT. ASOT shall pay in cash (and the Contribution Value shall not be reduced by) all transfer and assumption fees, lender’s attorneys’ fees (and any prepayment fees, penalties or premiums or any defeasance costs if ASOT, following the Closing elects to prepay or defease any Assumed Debt), and all other fees, costs and charges imposed by the lenders of the applicable Assumed Debt related to the contribution of the Assumed Debt Properties and the assumption of or taking subject to the Assumed Debt. The Contribution Value of each of the Subject to Debt Properties shall be reduced by the amount set forth on the applicable Loan Amount Statement with respect to the Subject to Debt Properties (other than by any amount that may be reflected thereon that the applicable Property Partnership will pay in cash in accordance with the following sentence), including the amount of any applicable prepayment premium thereon that would be required to be paid on the the Closing Date were the Subject to Debt being fully repaid by ASOT on the applicable Closing Date. The applicable Property Partnership or Property Partnerships shall pay in cash (and the Contribution Value shall not be reduced by) all transfer fees, and all other fees, attorneys’ fees, costs and charges imposed by the lenders of the applicable Subject to Debt related to the contribution of the Subject to Debt Properties and the taking subject to the Subject to Debt, provided, that, such applicable Property Partnership or Property Partnerships shall in no way be obligated to pay any

assumption fees or any similar fees which the lender may require in consideration for ASOT determining not to prepay the Subject to Debt immediately after Closing. The Contribution Value of all of the Properties, including the Assumed Debt Properties, shall be reduced by the amount of the Other Liabilities (including any accrued, unpaid interest) as reflected on the applicable Loan Amount Statement.

(iii) A Property may be both an Assumed Debt Property and a Subject to Debt Property if it is encumbered by both Assumed Debt and Subject to Debt, as described in the Debt Schedule. Such Properties shall be treated as Assumed Debt Properties for purposes of the Assumed Debt, and as Subject to Debt Properties for purposes of the Subject to Debt, relating thereto.

(iv) Not later than twenty (20) days before the Closing Date relating to each Property, the Property Partnership or Property Partnerships owning such Property (or tenancy-in-common interests therein) shall provide a statement from each lender or servicer relating to any Assumed Debt, Subject to Debt and/or Other Liabilities affecting such Property (each a “Loan Amount Statement”) setting forth (A) the then outstanding principal amount of such debt or liability and all accrued and unpaid interest thereon and any delinquent or past due amounts on such debt or liability and any late charges, fees or penalties associated therewith, (B) with respect to any such debt or liabilities being prepaid or defeased by the ASOT Acquiring Party immediately following the applicable Closing, the amount that would need to be paid in order for the ASOT Acquiring Party to fully discharge the same on the applicable Closing Date but immediately after the contribution of the Property, including all estimated (or the method of calculation of) prepayment, transfer and other fees, penalties and premiums (including lender’s attorney fees) that will be due to the lender in connection with the transfer of the Property to the ASOT Acquiring Party and the ASOT Acquiring Party’s subsequent prepayment or defeasance of such debt or liability, together with a per diem interest amount, and (C) with respect to any Assumed Debt which is “locked” or which is not being prepaid or defeased by the ASOT Acquiring Party following the applicable Closing, the outstanding amount of such Assumed Debt, including any accrued interest and any other outstanding amounts, together with the amount of any fees, costs or charges (including lender’s counsel fees) imposed by the lender in connection with the transfer of the Property and/or the assumption of the Assumed Debt, and a per diem interest amount. ASOT agrees that within 30 days of the Effective Date, ASOT will identify to the applicable Property Partnership or Property Partnerships in writing whether the applicable Property Partnership or Property Partnerships will need to provide a Loan Amount Statement pursuant to clause (B) of this Section 2.3(b)(iv) or clause (C) of this Section 2.3(b)(iv) with respect to the Assumed Debt.

2.4 Issuance of Units; Tax Treatment.

(a) Election of Units. Subject to Section 2.4(b), each Property Partnership (and its designated direct and indirect members or partners who are Accredited Investors) and the R&B Partners (and their designated direct and indirect partners who are Accredited Investors) may elect to receive the Contribution Value, as adjusted in accordance with this Article II, in cash or in Units, or partially in

Units. The number of Units to be issued to the applicable Property Partnership and/or its designated direct and indirect members or partners who are Accredited Investors and the R&B Partners (and their designated direct and indirect partners who are Accredited Investors) will be equal to the quotient of (i) that portion of the Contribution Value of the Property (or tenancy-in-common interests therein) or the R&B Property, as applicable, to be directly or indirectly contributed by such Property Partnership and the R&B Partners (less any reductions to the Contribution Value pursuant to Section 2.3 of this Agreement, less any amount paid for the Sold Property, and plus or minus the amount of any prorations as provided in the applicable Contribution Agreement) for which the applicable Property Partnership (and/or its designated direct or indirect members or partners who are Accredited Investors) or the R&B Partners (and its designated direct and indirect partners who are Accredited Investors) have elected to receive Units on or prior to the Unit/Cash Election Date as described in Section 2.4(b), divided by (ii) the Common Share Value. No fractional Units will be issued; instead ASOT shall round the number of Units to be issued to each Property Partnership (and/or its designated direct and indirect members or partners who are Accredited Investors) and the R&B Partners (and their designated direct and indirect members or partners) up or down to the nearest whole number of Units. The remainder of the Contribution Value of such Property (or tenancy-in-common interest therein) (less any reduction to the Contribution Value pursuant to Section 2.3 of this Agreement, less any amount paid for the Sold Property, and plus or minus the amount of any prorations as provided in the applicable Contribution Agreement) and/or the R&B Property will be paid in cash to the applicable Property Partnership (and/or its designated direct and indirect members or partners) or the R&B Partners (and their designated direct and indirect partners), as the case may be. Subject to Section 2.4(c), in case any Property (or tenancy-in-common interest therein) is owned directly or indirectly through a Subsidiary, and such Subsidiary is not contributed to ASOT, such cash or Units shall initially be delivered to such Subsidiary and may immediately thereafter be distributed to the Property Partnership (and its designated direct and indirect members or partners who are Accredited Investors) in accordance with the requirements of Section 2.4(b).

(b) Requirements. The Property Partnerships (and their designated direct and indirect members or partners who are Accredited Investors) and the R&B Partners (and their designated direct and indirect partners who are Accredited Investors) may only receive Units pursuant to Section 2.4(a) if (i) such Property Partnership (and/or its designated direct and indirect members or partners who are Accredited Investors) or such R&B Partner (and/or its direct and indirect partners who are Accredited Investors) elects in writing delivered to ASOT no later than the Unit/Cash Election Date applicable to such Property Partnership (and/or its designated direct and indirect members or partners who are Accredited Investors) or the R&B Partner (and/or its designated direct and indirect members or partners who are Accredited Investors) to receive all or a portion of the Contribution Value in Units in accordance with this Section 2.4, and (ii) such Property Partnership or such R&B Partner has delivered an Investor Questionnaire for such Property Partnership (and/or its designated direct and indirect members or partners who are requesting to receive Units) or such R&B Partner (and/or its direct and indirect partners who are Accredited Investors), respectively. In all events and notwithstanding anything to the contrary in this Agreement, if such Property Partnership, its designated

direct and indirect members or partners who are requesting to receive Units or such R&B Partner (and its direct and indirect partners who are requesting to receive Units), as the case may be, fails to qualify for or otherwise receive Units for reasons other than as a result of ASOT’s breach of this Agreement, such Property Partnership, such designated direct and indirect member or partner or such R&B Partner (and its direct and indirect partners), as the case may be, shall receive cash instead of Units, and the applicable Closing shall not be delayed or otherwise affected.

(c) Tax Treatment. Except with respect to any Properties (or tenancy-in-common interests therein) for which the Property Partnerships elect to receive only cash, ASOT agrees to structure the acquisitions described in this Article II as reasonably directed by R&B and the applicable Property Partnership, and to the extent permissible under applicable law, to accommodate the parties intent that (i) the acquisitions in exchange for Units constitute wholly tax-deferred contributions of property to a partnership (i.e., ASOT) by such Property Partnerships and their respective members and partners governed by Section 721 of the Code, and (ii) all cash paid by ASOT to any such Property Partnership constitutes (A) cash paid to reimburse such Property Partnerships for certain preformation capital expenditures described in regulations promulgated under Section 707 of the Code, (B) cash paid to purchase partnership interests in the Property Partnerships and R&B from certain of the partners and members of the Property Partnerships and R&B immediately before the contributions described in the foregoing clause (i) of this Section 2.4(c) in purchase transactions the tax treatment of which are governed by Section 741 of the Code, (C) a debt-financed transfer within the meaning of Treasury Regulation § 1.707-5(b), and/or (D) cash paid to purchase the Sold Property. With respect to Section 2.4(c)(ii)(B), to the extent permissible under applicable law, certain of these partnership interest acquisitions will be structured, pursuant to Treasury Regulation § 1.708-1(c)(4), as occurring in connection with assets-over mergers in which ASOT will be purchasing from those members of the R&B Group that elect to receive cash (the “Selling Partners”) all (or the designated portion) of their interests in the applicable Property Partnerships (collectively, the “Partnership Interests”) and the Selling Partners will consent to treat such sales as sales of the Partnership Interests to ASOT for Federal income tax purposes. The applicable Property Partnerships hereby acknowledge and agree that the consideration ASOT will be paying to the Selling Partners in exchange for their Partnership Interests under Section 2.4(c)(ii)(B) is the cash consideration referred to in such Section 2.4(c)(ii)(B) (along with any Property Partnership nonrecourse indebtedness to which such purchased Partnership Interest is subject) being delivered hereunder and no additional consideration shall be required, and ASOT shall not have any entitlement to liquidating distributions, if any, made by the applicable Property Partnership with respect to such purchased Partnership Interests. To the extent permissible under applicable law, the applicable Property Partnership and ASOT shall report (and the applicable Property Partnership shall cause each of the Selling Partners to report) the Partnership Interest transfers described in Section 2.4(c)(ii)(B), as the sale of partnership interests in a terminating partnership occurring as part of an “assets-over” merger. This Section 2.4(c) specifies (i) that the resulting partnership (ASOT) is purchasing partnership interests (the Partnership Interests) from a particular partner in the merging or consolidating partnership (each of the Selling Partners) and (ii) the consideration (the cash and liabilities to which the Partnership Interests are subject) that

is transferred for each interest sold, all as described in Treasury Regulation § 1.708-1(c)(4). In the event of a change in the applicable tax law prior to the applicable Closing Date, the parties hereto will reasonably cooperate to structure the transactions contemplated hereby to accommodate the intent of ASOT, R&B and the Property Partnerships as set forth in this Section 2.4(c).

(d) Registration Rights Agreement and Tax Agreement. At any Closing at which Units are to be issued, (i) ASOT and ASN shall enter into, and the applicable Property Partnership or Property Partnerships, the direct and indirect members or partners of any Property Partnership who are receiving Units, or the Property Partnerships on their behalf, or the R&B Partners (and their designated direct and indirect partners who are Accredited Investors), as the case may be, shall enter into, the Registration Rights Agreement and (ii) ASOT and ASN shall enter into and the applicable Property Partnership or Property Partnerships and the members or partners of any Property Partnership who are receiving Units, or the Property Partnerships on their behalf, shall enter into a Tax Agreement with respect to the applicable Property or Properties being contributed at such Closing.

2.5 Contribution of Title Holder Rather than Fee Title. Schedule 2.5 lists, with respect to each Property Partnership that indirectly owns a Property (or a tenancy-in-common interest therein), its Subsidiaries (and, in the case of a limited partnership subsidiary, the general partner thereof) that own(s) such Property (or tenancy-in-common interest therein) or that is the obligor on any Subject to Debt (each a “Title Owning Entity” and collectively, the “Title Owning Entities”). With respect to each Property (or a tenancy-in-common interest therein) owned by a Title Owning Entity, ASOT and the applicable Property Partnership or Property Partnerships will agree during the Due Diligence Period whether such Property Partnership or Property Partnerships will contribute such Property (or tenancy-in-common interests therein) to the ASOT Acquiring Party by deed or whether such Property Partnership or Property Partnerships will instead contribute all of the membership interests or partnership interests in the applicable Title Owning Entity to the ASOT Acquiring Party in lieu of conveying the Property (or tenancy-in-common interests therein) by deed to the ASOT Acquiring Party. Subject to ASOT’s obligations pursuant to Section 2.4(c) to structure the contributions as reasonably directed by R&B and the applicable Property Partnership or Property Partnerships to accommodate the parties’ agreement as described in Section 2.4(c), in the event the parties fail to so agree during the Due Diligence Period, the Property (or tenancy-in-common interests therein) will be conveyed by deed except with respect to the Properties identified on Schedule 2.1 attached hereto as the Las Colinas Property and the Dulles Property, which Properties will be acquired, to the extent reasonably required to permit the ASOT Acquiring Party to acquire such Properties subject to the Subject to Debt, by having the applicable Property Partnerships contribute the applicable Title Owning Entities. For those Property Partnerships that own their Properties directly, ASOT and the applicable Property Partnership will agree during the Due Diligence Period whether any such Property Partnership will contribute its Property to the ASOT Acquiring Party by deed or whether any such Property Partnership will merely change the method of holding title to such Property Partnership’s Property by contributing ownership of such Property to a newly formed limited liability company or partnership wholly owned by such Property Partnership that is disregarded for federal income tax purposes and which is reasonably acceptable to such Property Partnership and ASOT. The party requesting the contribution of a Property from a Property

Partnership to a Title Owning Entity shall bear the reasonable cost of such restructuring which would not have been incurred were it not for such restructuring, including all transfer and assumption fees, and all other fees, costs and charges imposed by the lenders of the applicable Subject to Debt or Assumed Debt which would not otherwise have been charged. Subject to Section 2.4(c), in the event the parties fail to agree during the Due Diligence Period upon the restructuring, the Property shall be conveyed by deed to the ASOT Acquiring Party without having been contributed to a limited liability company or partnership. Any action which a Property Partnership is required to take under this Agreement shall be binding upon any Title Owning Entity owned by such Property Partnership and any liability or obligation of any Property Partnership under this Agreement shall also be the liability and obligation of any Title Owning Entity it owns. Any action which ASOT is required to take under this Agreement shall be binding upon each ASOT Acquiring Party and any liability or obligation of any ASOT Acquiring Party under this Agreement shall also be the liability and obligation of ASOT.

Any Property Partnership contributing membership interests or partnership interests in any Title Owning Entity pursuant to this Section 2.5 shall assign, transfer, contribute and convey to the ASOT Acquiring Party all of the equity membership interests or partnership interests, as the case may be, and 100% of the economic interests in such Title Owning Entity (such interests being hereinafter collectively referred to as the “Membership Interests”), including, without limitation, the following: (i) all interests in the capital of such Title Owning Entity and all profits, surplus, assets, allocations, returns (whether preferred or not) and distributions of any kind of the Title Owning Entity to which the applicable Property Partnership shall at any time be entitled to the extent attributable to the period after the applicable Closing; (ii) all other payments, if any, due or to become due, under or arising out of that certain operating or partnership agreement of such Title Owning Entity, whether as contractual obligations, damages, insurance proceeds, condemnation awards or otherwise arising out of such agreement to the extent attributable to the period after the applicable Closing; (iii) any interest in real, personal, intangible or other property which the applicable Property Partnership may hold or be entitled to as of the applicable Closing as a result of its interest in such Title Owning Entity; (iv) all of the applicable Property Partnership’s claims, rights, powers, privileges, authority, options, security interests, liens and remedies, if any, against, under or in respect of its interest in such Title Owning Entity, or under or arising out of its operating or partnership agreement; (v) all present and future claims, if any, of the applicable Property Partnership against such Title Owning Entity for monies loaned or advanced or for services rendered (or otherwise arising under or out of the operating or partnership agreement of such Title Owning Entity); (vi) any and all rights and powers of the applicable Property Partnership as the sole equity member or partners of such Title Owning Entity under its operating or partnership agreement; and (vii) any and all claims, demands, actions, causes of action, judgments, obligations, contracts, agreements, debts and liabilities whatsoever, whether known or unknown, suspected or unsuspected, both at law and in equity (“Claims”) which the applicable Property Partnership (or its heirs, executors, administrators, successors and assigns) now has, has ever had or may hereafter have against such Title Owning Entity and, to the extent any such Claim may give rise (directly or indirectly) to any claim for indemnification, contribution or reimbursement from such Title Owning Entity, its affiliates (or its respective predecessors in interest), its past and present agents, representatives, employees, officers, directors, partners, members, controlling persons, subsidiaries, successors and assigns, including, without limitation, any rights to indemnification or reimbursement from them (or their respective predecessors in interest); provided, however, ASOT hereby

acknowledges and agrees that neither it nor, following the applicable Closing, the Title Owning Entity, shall pursue any Claim assigned as part of the Membership Interest against any Property Partnership (or its heirs, executors, administrators, successors and assigns). The term “Membership Interests” shall not include any fees payable to R&B and/or any Affiliate thereof or loans or fees constituting Other Liabilities. Nothing herein contained shall preclude a Title Owning Entity from making or paying (and each Property Partnership shall have the right to cause the applicable Title Owning Entity to make or pay) any distribution of cash, cash equivalents, and/or interests in any and all reserves and/or impounds held by any and all third parties (including tax, insurance and loan reserves which the applicable third party might not release until following the applicable Closing) to a Property Partnership prior to the applicable Closing, and any such distribution shall not be assigned by the Property Partnership to the ASOT Acquiring Party with the assignment of the Membership Interests. ASOT acknowledges that the ASOT Acquiring Party shall have no right, title or interest in any such distribution, and ASOT hereby agrees that each Title Owning Entity may distribute to the applicable Property Partnership prior to the applicable Closing any and all cash, cash equivalents, reserves, impounds and/or interests or other rights in and to cash, cash equivalents, reserves and/or impounds held by such Title Owning Entity (or third party) attributable to the Title Owning Entity’s ownership of the Property prior to the applicable Closing.

2.6 Toluca Hills Development Rights. In addition to its contribution of the developed portion of the Toluca Hills Property, the Property Partnership that owns the Toluca Hills Property shall contribute the Toluca Hills Development Parcel described on Schedule 2.6 attached hereto, to the ASOT Acquiring Party in exchange for 1,000 Series N Preferred Units, subject to such Property Partnership being qualified as an Accredited Investor at the time of the applicable Closing. If such Property Partnership is not an Accredited Investor immediately prior to Closing, then cash shall be paid by ASOT to the Property Partnership in an amount equal to $250,000.

2.7 The Put Rights.

(a) Newport Put Agreement. After the Effective Date, Newport Beach will identify the proposed Newport Property and Newport Beach and ASOT will endeavor in good faith to agree upon the Newport Property. Newport Beach will not enter into a Contribution Agreement with an ASOT Acquiring Party with respect to the Newport Property. Rather, so long as the Newport Property is acceptable to ASOT, after ASOT’s due diligence review of the Newport Property during the Due Diligence Period in accordance with Section 3.2 (or during the due diligence period under the purchase agreement for the acquisition of the Newport Property by Newport Beach, if applicable), Newport Beach and ASOT will enter into the Newport Put Agreement on the First Closing Date, pursuant to which Newport Beach will have the right (but not the obligation) to contribute the Newport Property to ASOT or a Qualified Designee in accordance with the terms of the Newport Put Agreement. Newport Beach shall pay ASOT Two Hundred Fifty Thousand Dollars ($250,000) for the rights set forth in the Newport Put Agreement. Until the earlier of (i) the expiration of the Newport Put Agreement and (ii) in the event Newport Beach exercises the Newport Put Right, such time as ASOT or a Qualified Designee acquires the Newport Property pursuant to the Newport Put Agreement, the Newport Property shall be managed by a third-party

property manager hired by Newport Beach and approved by ASOT, at the sole cost and expense of Newport Beach.

(b) Philadelphia Put Agreement. Mid-Wilshire will not enter into a Contribution Agreement with an ASOT Acquiring Party with respect to the Philadelphia Property. Rather, Mid-Wilshire and ASOT will enter into the Philadelphia Put Agreement on the First Closing Date, pursuant to which Mid-Wilshire will have the right (but not the obligation) to contribute the Philadelphia Property to ASOT or a Qualified Designee in accordance with the terms of the Philadelphia Put Agreement. Mid-Wilshire shall pay ASOT One Hundred Thousand Dollars ($100,000) for the rights set forth in the Philadelphia Put Agreement. ASOT will complete it due diligence review of the Philadelphia Property during the Due Diligence Period in accordance with Section 3.2. Upon the contribution of the Philadelphia Property in accordance with the terms and provisions of the Philadelphia Put Agreement, ASOT or a Qualified Designee shall enter into a Master Lease with R&B with respect to the Philadelphia Property pursuant to which the first year rental rate shall be Nine Hundred Twenty-Nine Thousand Three Hundred Fifty-Three Dollars ($929,353). Until the earlier of (i) the expiration of the Philadelphia Put Agreement and (ii) in the event Mid-Wilshire exercise the Philadelphia Put Right, such time as ASOT or a Qualified Designee acquires the Philadelphia Property pursuant to the Philadelphia Put Agreement, the Philadelphia Property shall be managed by R&B.

ASOT has delivered to R&B the Disclosure Materials Objections Schedule consisting of objections to the Disclosure Materials (“Objection Items”).

Such notice shall specify in reasonable detail the issues that will remain open during such thirty-day extension, and will waive ASOT’s right to terminate this Agreement pursuant to Section 3.4 based upon any other due diligence matters.

(a) Delivery of Specified Documents. Within five Business Days after the Effective Date, R&B shall provide or make available to ASOT the following information relating to each Property (the “Property Information”) to the extent located upon one of the Properties or R&B’s executive office and not previously delivered to ASOT among the Disclosure Materials or Delayed Disclosure Materials: (i) the latest property tax bills from all taxing authorities; (ii) the most recent environmental reports; (iii) all existing plans, specifications, permits, approvals (and any applications for permits or approvals), maps and surveys (including, without limitation, archaeological, boundary, topographic and tree surveys); (iv) any subdivision reports; (v) any soils and engineering reports; (vi) any written notices, reports, citations, orders, decisions, correspondence, or memoranda from any governmental authority (including, but not limited to, copies of any zoning letters) for any uncured violations; (vii) all existing written agreements with or applications to any governmental authority with respect to any zoning modification, variance, exception, platting or other matter relating to the zoning, use, development, subdivision or platting of the Property; (viii) copies of all agreements, studies, reports, correspondence and other documents relating to the presence or absence of any endangered species or environmentally sensitive areas on the Property; and (ix) any existing written contracts or agreements relating to the Property or services being provided or to be provided to the Property, including, without limitation, any agreements with electric, cable, gas, telephone or other utility providers. The Property Partnerships shall provide or make available to ASOT any documents described above and coming into any of R&B’s, the applicable Property Partnership’s or its Subsidiaries’ possession or produced by any Property Partnership or its Subsidiary after the initial delivery or availability above and shall continue to provide or make available the same prior to the Closing Date for the applicable Property.

(b) Confidentiality. ASOT, ASN and all of their Representatives (as defined below) (collectively, the “Recipient”) will hold all non-public information obtained in connection with their due diligence or otherwise in strict confidence and shall not, except as otherwise required by law or by any regulatory authority, without the prior written consent of R&B and the applicable Property Partnership, disclose such information or the fact that any such information has been made available, except that the Recipients may disclose the information to those of Recipients’ Affiliates, directors, officers, employees, attorneys, accountants, and, with the applicable R&B Group member’s prior consent and approval, lenders and prospective lenders (and their attorneys and accountants), consultants and advisors (collectively, “Representatives”) who (x) need to know the information for the purpose of evaluating the proposed transaction and (y) have been informed of the confidential nature of the information and agree to keep the information confidential. Notwithstanding any such agreement by Recipient’s Representatives, Recipient agrees to be responsible for and to indemnify the applicable member of the R&B Group against any breach by Recipient and any of Recipient’s Representatives of the agreements made herein. Recipient agrees that any and all requests for information shall be made through only Xxxxxxx Xxxxxxxxx and any individual designated by Xxxxxxx Xxxxxxxxx and that no other employees of R&B or partners or members of the Property Partnerships or their Affiliates shall be contacted by Recipient or the Representatives, except that Recipients may also discuss the transactions contemplated hereby and matters relating thereto with representatives of the general partners of the Property Partnerships.

Notwithstanding the foregoing, each party hereto (and each employee, agent or representative of the foregoing) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the transactions contemplated by this letter of intent and all materials of any kind (including opinions or other tax analyses) that are provided or made available to the party relating to such tax treatment and tax structure except to the extent maintaining such confidentiality is necessary to comply with any applicable federal or state securities laws. In the event that this Agreement is terminated, ASOT shall promptly return to R&B any and all statements, documents, schedules, exhibits, reports and all other written information obtained from R&B and/or the Property Partnerships in connection with this Agreement for the transactions contemplated herein, together with any copies made by ASOT, and shall promptly destroy copies of any and all reports and compilations generated by ASOT and its Representatives from materials or other information provided or made available to ASOT by R&B and/or the Property Partnerships. The confidentiality obligations herein shall survive any termination of this Agreement.

(c) ASOT’s Inspection. During the term of this Agreement, ASOT and its agents shall have the right, though subject to the rights of the tenants under their leases, to inspect the Properties during normal business hours at a time mutually acceptable to R&B and ASOT and upon not less than twenty-four (24) hours prior request to R&B (or forty-eight (48) hours notice in the event that ASOT desires to inspect the leased premises of a tenant), in order to make, at ASOT’s sole cost and expense, such inspections and surveys of a Property as ASOT may desire; provided, however, that without R&B’s and the applicable Property Partnership’s prior written consent (which consent may be withheld in R&B’s sole and absolute discretion), ASOT shall not be entitled to perform or cause to be performed any destructive testing, any invasive environmental testing or any sampling or testing of the indoor air. ASOT also agrees to provide R&B and the applicable Property Partnership with copies of any written inquiry or request directed at any governmental official with respect to any Property prior to transmitting the same to any such official and to give R&B and the applicable Property Partnership notice and an opportunity to be present at any meetings with any such official; provided, however, that nothing in this sentence shall be deemed to prevent ASOT from inspecting or reviewing any or all records of any federal, state, or local governmental authority or requesting such authority to confirm that no violations of law exist at any Property within such authority’s jurisdiction. Subject to obtaining R&B’s and the applicable Property Partnership’s consent when required as specified above, ASOT’s inspections and tests may include, among other things, examination of the physical condition of the Property, any mechanical equipment, Phase I environmental site assessment, including radon gas testing, asbestos analysis, lead based paint analysis, and fuel or chemical storage tank investigation, if applicable, soils studies and seismic studies. ASOT shall not be entitled to enter any Property unless a representative of R&B or the applicable Property Partnership is present. ASOT and ASN shall indemnify, defend and hold the R&B Group and the Properties harmless from and against any and all expenses, costs, fees, suits, actions, obligations, liabilities, damages (including attorneys’ and expert witness fees and costs) caused by actions of ASOT and its Representatives during such entry, but excluding the discovery of any pre-existing adverse condition of any Property, except that ASOT shall be liable for any aggravation it causes to any pre-

existing adverse conditions. ASOT shall not cause or permit any liens or encumbrances upon any Property or any interest therein to result from ASOT’s or its Representatives’ acts with regard to such Property and shall promptly repair any damage to the Properties which may result from the entry and inspections on the Properties by ASOT or its Representatives.

(d) Insurance Coverage. Commencing with ASOT’s first entry onto a Property and at all times prior to the applicable Closing, ASOT shall have in effect commercial general liability (or a combination of primary general liability, umbrella liability and excess) insurance naming the Property Partnerships, the Title Owning Entities and R&B as additional insureds on a primary, non-contributing basis, with (i) waiver of subrogation; and (ii) limits of not less than $5,000,000 combined single limit for bodily and personal injury and property damage. ASOT shall deliver to R&B certificates of insurance evidencing such coverage within five days following the Effective Date.

3.3 Title and Survey Examination. Within two (2) Business Days after the Effective Date, ASOT shall obtain with respect to each Property a current, effective commitment for title insurance, if available in the applicable jurisdiction, or preliminary title report (each, a “Title Commitment”) issued by Chicago Title Insurance Company, 000 Xxxxx Xxxxxx Xxxxxx, Xxxxx 0000, Xxx Xxxxxxx, Xxxxxxxxxx 00000 (the “Title Company”), in the amount of the applicable Contribution Value for each Property, with the ASOT Acquiring Party as the proposed insured, and accompanied by true, complete, and legible copies of all documents referred to in the Title Commitments. ASOT has directed to be prepared a current ALTA-ACSM survey (the “Survey”) for each Property.

(a) Title Review and Cure. During the Due Diligence Period, ASOT shall review title to each Property as disclosed by the Title Commitments and the Surveys. The Property Partnerships and its Subsidiaries will cooperate with ASOT, at ASOT’s sole cost and expense, in curing any objections ASOT may have to title to any Property. The Property Partnerships and its Subsidiaries shall have no obligation to cure title objections except monetary liens (other than those set forth in the Debt Schedule) of an ascertainable amount voluntarily created by the applicable Property Partnership (or its Subsidiaries, as applicable), which liens the Property Partnerships and their Subsidiaries shall cause to be released at the Closing. The Property Partnerships agree to remove, and to cause their Subsidiaries to remove, any exceptions or encumbrances to title relating to monetary liens (other than those set forth in the Debt Schedule) which are voluntarily created by such entity after the Effective Date without ASOT’s consent, which consent shall not be unreasonably withheld, conditioned or delayed. If the Title Company revises the Title Commitment relating to a Property after the expiration of the Due Diligence Period to add or modify exceptions (except for additions or modifications made at the request of ASOT), an R&B MAE with respect to such Property shall be deemed to exist if, in ASOT’s reasonable judgment, such additions or modifications materially and adversely affect title to the Property or the use or the operations of the Property and are not removed by the Closing Date.

(b) Title Policies. The Title Company shall deliver to the ASOT Acquiring Party with respect to each Property at Closing an ALTA Form 1970 (revised 1984) (or other form required by state law) Owner’s Policy of Title Insurance (the “Title Policy”), with extended coverage (i.e., with ALTA General Exceptions [1 through 5 deleted], or with corresponding deletions if a Property is located in a non-ALTA state), issued by the Title Company as of the date and time of the applicable Closing, in the amount of the Contribution Value, containing ASOT’s Endorsements, insuring the ASOT Acquiring Party (or the Title Owning Entity, if applicable) as owner of good, marketable and indefeasible fee simple title to each Property, and subject only to the Permitted Exceptions. The cost of the Title Policies shall be paid by the party or parties specified in Schedule 3.3(b) hereto. “ASOT’s Endorsements” shall mean, to the extent such endorsements are available under the laws of the state in which a Property is located: (a) owner’s comprehensive; (b) access; (c) survey (accuracy of survey); (d) location (survey legal matches title legal); (e) separate tax lot; (f) subdivision; (g) zoning 3.1, with parking; and (h) such other endorsements as ASOT may reasonably require (including, without limitation, non-imputation and Fairway endorsements). The applicable Property Partnership (or its Subsidiaries, as applicable) shall execute at Closing an affidavit and other documents in such form as the Title Company shall, in the sole and absolute discretion of the applicable Property Partnership, reasonably require for the issuance of the Title Policies. The Title Policies may be delivered after the Closing if at the Closing the Title Company issues currently effective, duly-executed “marked-up” Title Commitments for each Property and irrevocably commits in writing to issue a Title Policy for each Property in the form of the “marked-up” Title Commitments promptly after the Closing Date. The term “Permitted Exceptions” shall mean: (i) the specific exceptions (exceptions that are not part of the promulgated title insurance form) in each Title Commitment that the Title Company has not agreed to insure over or remove from the Title Commitment as of the end of the Due Diligence Period and that the Property Partnerships and its Subsidiaries, as applicable, are not required to remove as provided above; (ii) real estate taxes and assessments not yet due and payable; (iii) tenants in possession as tenants only under leases without any right of first refusal, option to purchase or acquire an interest in any Property; (iv) the instruments evidencing the Assumed Debt, the Subject to Debt and the Other Liabilities; and (v) any matters which are disclosed by the Survey, or, if no Survey is obtained, which would be disclosed by an accurate survey or physical inspection of the applicable Property.

3.4 Termination During Due Diligence Period. ASOT may terminate this Agreement as to any Property or Properties and/or the R&B Property by written notice to R&B and/or the applicable Property Partnership delivered prior to the expiration of the Due Diligence Period specifying, with respect to such Property or Properties, any circumstance, event, occurrence, change or effect not waived pursuant to Section 3.1 that, individually or in the aggregate, has had a materially adverse effect on the Title Owning Entity, if the ASOT Acquiring Party is to acquire the Title Owning Entity, and/or the Property or its results of operations, except in each case, (i) changes in general economic conditions nationally, regionally or within the market in which the Property is located; (ii) changes in ASOT’s internal underwriting standards, assumptions or criteria applied to the evaluation of properties; or (iii) changes in the real estate industry generally and the multi-unit apartment leasing market specifically, which do not affect such Property materially disproportionately relative to other similar real estate similarly situated (a

“Due Diligence MAE”); provided, however, that as to any matters set forth in the Disclosure Materials, only the Objection Items shall be taken into account in determining whether there exists a Due Diligence MAE. In the event ASOT terminates this Agreement pursuant to this Section 3.4 as to any ASOT Key Property, ASOT shall have the right, but not the obligation, to terminate this Agreement in its entirety by notice delivered within five (5) days after the expiration of the Due Diligence Period. In the event ASOT terminates this Agreement under this Section 3.4 as to (i) any of the R&B Key Properties or the R&B Property or (ii) four or more of the other Properties, R&B and the Property Partnerships shall have the right, but not the obligation, to terminate this Agreement in whole or in part (provided that, if R&B and one or more of the Property Partnerships determine to terminate this Agreement only in part, R&B and the Property Partnerships shall not be permitted to terminate this Agreement as to any ASOT Key Property) pursuant to this Section 3.4 or Section 11.2 by notice delivered within five (5) days after R&B and the Property Partnerships have received notice from ASOT of its termination of this Agreement with respect to (i) any of the R&B Key Properties or (ii) four or more of the other Properties. Notwithstanding anything to the contrary in the foregoing, prior to terminating this Agreement, in whole or as to any Property, ASOT, R&B and the applicable Property Partnership(s) each hereby agrees to cooperate in good faith in resolving, to ASOT’s reasonable satisfaction, any issues identified during the Due Diligence Period.

4.3 Governmental Action.

To the Applicable Person’s Actual Knowledge, the operating statements for the past three years provided by R&B to ASOT are true and correct copies of such statements furnished to the applicable Property Partnership by its property management company.

At the applicable closing, R&B Realty Group II will own all of the assets set forth on Schedule 2.2 free and clear of any and all liens, and such assets will be the only assets that R&B Realty Group II has owned, directly or indirectly since its formation. None of the Title Owning Entities or R&B Realty Group II own, control or hold with the power to vote, directly or indirectly, any shares of capital stock or beneficial interest in any corporation, partnership, limited liability company, association, joint venture or other entity, except for another Title Owning Entity.

4.15 Due Diligence Materials. R&B has made available to ASOT all of the Property Information, Disclosure Materials and all other materials and information about the Properties which are located upon the Properties or R&B’s executive office, and where interests in Title Owning Entities are being conveyed, about those entities, which are located upon the Properties or R&B’s executive office, excluding any information which is covered by the attorney-client or attorney work product privilege. To the Applicable Person’s Actual Knowledge, the copies of any Property Information and Disclosure Materials delivered to ASOT are true and correct copies of the originals, and no information or materials which are located upon the Properties or R&B’s executive office has been deliberately withheld with the effect of making the Disclosure Materials or the Property Information, or any other materials delivered or made available to ASOT, materially misleading.

Nothing in this Agreement shall purport to bind or create any obligation on the part of any partner or member of a Property Partnership whose consent to the transaction as contemplated hereby is required under the documents governing the Property Partnership but has not yet been obtained or is qualified by certain other agreements.

4.18 Title Owning Entities Not Reporting Company. None of the Title Owning Entities nor R&B Realty Group II is required to file reports pursuant to Sections 12(g) or 15(d) of the Securities Exchange Act of 1934, as amended.

If Membership Interests are to be contributed pursuant to this Agreement, then the applicable Property Partnerships will at least thirty (30) days prior to the applicable Closing Date deliver to ASOT copies of the financial statements for the applicable Title Owning Entities that are existing on the Effective Date (collectively, the “Financial Statements”). Each of the Financial Statements has been or will be prepared on a modified cash basis with depreciable assets being recorded on an income tax basis, and to the Applicable Person’s Actual Knowledge, each presents fairly the financial position of the applicable Title Owning Entity, as of its date and the results of their operations, as the case may be. Since the date of the most recent Financial Statements, to the Applicable Person’s Actual Knowledge, there has been no circumstance, event, occurrence, change or effect that has had a materially adverse effect on the financial condition of the Title Owning Entity, other than, in each case, as a result of (i) changes in general economic conditions nationally, regionally or within the market in which the Property is located; and (ii) changes in the real estate industry generally and the multi-unit apartment leasing market specifically. Except as set forth in the Financial Statements and the Debt Schedule, to the Applicable Person’s Actual Knowledge, the Title Owning Entities have no material (for purposes of this sentence, “material” means $25,000 or more in the aggregate) liabilities, debts, claims or obligations, whether accrued, absolute, contingent or otherwise, whether due or to become due, other than trade payables and accrued expenses incurred in the ordinary course of business since the date of the Financial Statements.

True, correct and complete copies of the Certificates of Formation, Certificates of Partnership, the limited liability company agreements, partnership agreements, the articles of incorporation and bylaws, as applicable (or similar organizational instruments), as amended, for the Title Owning Entities will be delivered to ASOT within ten (10) days of the Effective Date, and for R&B Realty Group II will be delivered at least thirty (30) days prior to the Closing of the contribution of the R&B Property.

ASOT and each of the applicable Property Partnerships shall cooperate in all respects with such efforts.

ASOT shall also use good faith, commercially reasonable efforts to secure the agreement of the lenders to release the Property Partnership (and any principal having guarantied the Subject to Debt) from all liability for matters accruing after the contribution if ASOT determines not to repay the Subject To Debt immediately after the applicable Closing (provided, however, if ASOT is unable to obtain such a release, it will indemnify, defend and hold wholly harmless the Property Partnership (and its principal having guarantied the Subject to Debt) against matters first arising or accruing after the applicable Closing Date and matters accruing prior to the Closing Date with respect to environmental and hazardous materials liabilities (including, without limitation,

attorneys’ and expert witness fees and costs) and ASOT’s failure to obtain such a release shall not constitute a condition precedent to ASOT’s or the Property Partnership’s obligation to close the acquisition of the affected Property). ASOT and each of the applicable Property Partnerships shall reasonably cooperate in all reasonable respects to obtain the requisite consents and acknowledgments. Notwithstanding the foregoing, the parties acknowledge that they will not take such actions with the lenders for the Newport Property or the Philadelphia Property, until such time as Newport Beach or Mid-Wilshire exercises its rights under the Newport Put Agreement and the Philadelphia Put Agreement, respectively.

With respect to Section 11.5(e) above, the liquidated damages amount shall be the sole and exclusive remedy at law, tort, contract or otherwise for the failure or breach described therein. Notwithstanding the foregoing, the prevailing party shall not be precluded from seeking Costs pursuant to Section 13.14.

11.6 Effect of Termination. If this Agreement is terminated in its entirety in accordance with the foregoing provisions of this Article XI, then except as hereinafter provided, all obligations of the parties hereunder shall terminate. Notwithstanding anything to the contrary in the foregoing, ASOT’s confidentiality and indemnity obligations set forth in Section 3.2 (b), ASOT’s indemnity obligations set forth in Section 3.2(c), the parties’ respective payment obligations set forth in Section 11.5, and the parties respective obligations set forth in Section 13.14 shall survive any such termination. If this Agreement is terminated with respect to one or more Properties or the R&B Property, then except as hereinafter provided, all obligations of the parties hereunder with respect to the applicable Property or Properties or R&B Property, as the case may be shall terminate. Notwithstanding anything to the contrary in the foregoing, ASOT’s confidentiality and indemnity obligations set forth in Section 3.2 (b), ASOT’s indemnity obligations set forth in Section 3.2(c), the parties respective payment obligations set forth in Section 11.5, and the parties respective obligations set forth in Section 13.14 as they may relate to the terminated Property or R&B Property, as the case may be, shall survive any such termination.

Neither ASOT nor R&B or the Property Partnerships shall have any liability with respect to claims first asserted in connection with any representation or warranty after the survival period specified therefor in this Section 12.1.

12.2 Indemnification by the R&B and the Property Partnerships. Subject to Sections 12.1 and 12.4, each of R&B and the Property Partnerships, (i) jointly and severally, with respect to Sections 12.2(a) and 12.2(d), and (ii) severally with respect to Sections 12.2(b) and 12.2(c) and then each only to the extent related to such Property Partnership or its Property, agree to indemnify ASOT against, and agrees to hold ASOT harmless from, any and all Losses incurred or suffered by ASOT arising out of any of the following:

(a) any breach of or any inaccuracy in any representation or warranty made by R&B and the Property Partnerships in this Agreement or the Contribution Agreement; provided, however, that any breach of or any inaccuracy in any of the Title Owning Entity Warranties or with respect to any Title Owning Entity or R&B Realty Group II shall only be applicable with respect to the contribution of the applicable Membership Interests or the R&B Membership Interests, respectively, and only to the extent made with respect thereto;

(b) any amount in excess of the amount shown on any Loan Amount Statement that any lender claims would have been required to have been paid on the applicable Closing Date to fully discharge the applicable Subject To Debt, the Assumed Debt and the Other Liabilities on the applicable Closing Date (were the Subject To Debt, the Assumed Debt and the Other Liabilities fully repaid and discharged by ASOT on the applicable Closing Date) other than, with respect to the Assumed Debt, increases in yield maintenance prepayment premiums resulting from changes in the variables used in the applicable yield maintenance calculation and defeasance costs;

(c) any claims, suits or proceedings brought against ASOT or ASN asserted by any non-managing member or limited partner of a Property Partnership, other non-contributing owner (a party that does not receive cash or Units) parties (including governmental agencies) other than the parties to this Agreement in connection with the solicitation of their consent and approval to the transactions contemplated by this Agreement or any act, omission, agreement of, or circumstance (or alleged act, omission, agreement of, or circumstance) involving such solicitation, including any claim alleging

breach of fiduciary duties, except for claims based on information provided by ASOT or ASN and included in the Information Statement; or

(d) any breach of or failure by R&B and the Property Partnerships to perform any covenant or obligation of R&B and the Property Partnerships set out in this Agreement or the Contribution Agreement or any document delivered by a member of the R&B Group at the applicable Closing (provided, however, the consequences of any failure or breach with respect to the Tax Agreement, the Registration Rights Agreement and the Master Lease, shall be governed by the applicable provisions of such agreements and not the provisions of this Section 12.2 and not subject to the limitations contained in Section 12.4).

12.3 Indemnification by ASOT and ASN. ASOT and ASN agree to indemnify R&B and the Property Partnerships against, and agrees to hold R&B and the Property Partnerships harmless from, any and all Losses incurred or suffered by R&B and the Property Partnerships arising out of any of the following:

(a) any breach of or any inaccuracy in any representation or warranty made by ASOT or ASN in this Agreement or the Contribution Agreement or any document delivered by ASOT or ASN at the applicable Closing;

(b) claims asserted by any non-managing member or limited partner of a Property Partnership or other non-contributing owner (a party that does not receive cash or Units) in connection with the solicitation of their consent and approval to the contemplated transactions to the extent such claims are attributable in whole or in part to information provided by ASOT or ASN that is included in the Information Statement;

(d) any breach of or failure by ASOT or ASN to perform any covenant or obligation of ASOT of ASN set out in this Agreement or the Contribution Agreement or any document delivered by ASOT or ASN at the applicable Closing (provided, however, the consequences of any failure or breach with respect to the Tax Agreement, the Registration Rights Agreement and the Master Lease, shall be governed by the applicable provisions of such agreements and not the provisions of this Section 12.3 and not subject to the limitations contained in Section 12.4).

12.4 Limitations on Liability. Notwithstanding any other provision of this Agreement, ASOT and R&B and the Property Partnerships shall have the right to payment under Sections 12.2(a) and 12.2(d) (other than breaches of any Tax Warranties and Covenants) and Sections 12.3(a) and 12.3(d) (other than breaches of any Tax Warranties and Covenants), respectively, only if, and only to the extent that, the party seeking indemnity and recovery thereunder shall have suffered actual losses as a result of any such breach of representation, warranty or covenant, which when aggregated with all other breaches, are in an amount exceeding $3,000,000 (as may be adjusted below and excluding any actual losses asserted to have been suffered in connection with a breach or failure for which liquidated damages were paid); provided, that, once such

threshold has been reached, the indemnitee shall be entitled to seek indemnification for the first $3,000,000 (as may be adjusted below and excluding any actual losses asserted to have been suffered in connection with a breach or failure for which liquidated damages were paid) in addition to any excess amounts; provided, further however, that in no event will either ASOT or R&B and the Property Partnerships be required to indemnify the R&B Group or ASOT, respectively, or otherwise be liable for amounts in excess of an aggregate cumulative recovery of $20,000,000 (as may be adjusted below and excluding any actual losses asserted to have been suffered in connection with a breach or failure for which liquidated damages were paid) under Sections 12.3(a) and 12.3(d) or Sections 12.2(a) and 12.2(d), respectively; provided, further however that the limits and thresholds with respect to indemnification described in this Section 12.4 shall not apply with respect to any of the Property Partnership’s or R&B’s Losses as a result of any breach of the representations, warranties or covenants contained in Sections 5.1 (Authority; Enforceability), 5.5 (Non-Assessable Units and Common Shares) or 5.9 (Tax Status) or with respect to any of ASOT’s or ASN’s Losses as a result of any breach of the representations, warranties or covenants contained in Sections 4.16 (FIRPTA Representations), 4.24 (Taxes) or 6.11 (Tax Returns). In the event that this Agreement or any Contribution Agreement is terminated with respect to one or more of the Properties and/or the R&B Property, the amount of the foregoing monetary limitations shall be reduced to an amount equal to the product of (x) such monetary limitation multiplied by (y) a fraction (A) the numerator of which is the aggregate Contribution Value of such Properties and/or the R&B Property and (B) the denominator of which is the aggregate Contribution Value and/or the R&B Property of all of the Properties and the R&B Property and, notwithstanding the otherwise joint and several liability of the Property Partnerships and R&B set forth in Section 12.2 above, if this Agreement or the applicable Contribution Agreement has been terminated with respect to all of the Properties directly or indirectly owned by such Property Partnership then such Property Partnership shall have no obligation to provide indemnity under this Article XII.

12.5 Claims. As promptly as is reasonably practicable after becoming aware of a claim for indemnification under this Agreement not involving a third-party claim under Section 12.6, or the commencement of any suit, action or proceeding, of the type described in Section 12.6, but in any event no later than twenty (20) Business Days after first becoming aware of such claim, the Indemnified Party shall give notice to the Indemnifying Party of such claim, which notice shall specify the facts alleged to constitute the basis for such claim, the representations, warranties, covenants and obligations alleged to have been breached and the amount that the Indemnified Party seeks hereunder from the Indemnifying Party, together with such information as may be necessary for the Indemnifying Party to determine that the limitations in Section 12.4 have been satisfied or do not apply; provided, that the failure of the Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations under this Article XII except to the extent (if any) that the Indemnifying Party shall have been prejudiced thereby.

12.6 Notice of Third Party Claims; Assumption of Defense. The Indemnified Party shall give notice as promptly as is reasonably practicable, but in any event no later than fifteen (15) Business Days after receiving notice thereof, to the Indemnifying Party of the assertion of any claim, or the commencement of any suit, action or proceeding, by any Person not a party hereto in respect of which indemnity may be sought under this Agreement (which notice shall specify in reasonable detail the nature and amount of such claim together with such information as may be necessary for the Indemnifying Party to determine that the limitations in Section 12.4

have been satisfied or do not apply); provided, that the failure of the Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations under this Article XII except to the extent (if any) that the Indemnifying Party shall have been prejudiced thereby. The Indemnifying Party may, at its own expense, (a) participate in the defense of any such claim, suit, action or proceeding and (b) upon notice to the Indemnified Party, at any time during the course of any such claim, suit, action or proceeding, assume the defense thereof with counsel of its own choice and in the event of such assumption, shall have the exclusive right, subject to clause (i) of Section 12.7, to settle or compromise such claim, suit, action or proceeding. If the Indemnifying Party assumes such defense, the Indemnified Party shall have the right (but not the duty) to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Party. Whether or not the Indemnifying Party chooses to defend or prosecute any such claim, suit, action or proceeding, all of the parties hereto shall cooperate in the defense or prosecution thereof.

12.7 Settlement or Compromise. Any settlement or compromise made or caused to be made by the Indemnified Party (unless the Indemnifying Party has the exclusive right to settle or compromise under clause (b) of Section 12.6) or the Indemnifying Party, as the case may be, of any such claim, suit, action or proceeding of the kind referred to in Section 12.6 shall also be binding upon the Indemnifying Party or the Indemnified Party, as the case may be, in the same manner as if a final judgment or decree had been entered by a court of competent jurisdiction in the amount of such settlement or compromise; provided, that (i) no obligation, restriction or Loss shall be imposed on the Indemnified Party as a result of such settlement or compromise without its prior written consent, which consent shall not be unreasonably withheld, and (ii) the Indemnified Party will not compromise or settle any claim, suit, action or proceeding without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld.

12.8 Purchase Price Adjustments. To the extent permitted by law, any amounts payable under Section 12.2 or Section 12.3 shall be treated by as an adjustment to the Contribution Value.

12.9 Sole Remedy. To the extent permitted by law, the amounts payable under Section 12.2 and Section 12.3 shall be the sole and exclusive remedy at law, tort, contract or otherwise of the parties hereunder with respect to any breach of representations, warranties or covenants hereunder.
