At the Closing, the Contributor shall contribute, transfer, assign, convey and deliver to the Operating Partnership, and the Operating Partnership shall assume, absolutely and unconditionally and free and clear of all Liens other than Permitted Exceptions, but without recourse, representation or warranty except as expressly set forth herein, all of Contributor’s undivided right, title and interest in and to the Property and the obligations with respect thereto. The contribution of the Property shall be evidenced by the Transfer Documents (as defined below).

Section 1.2 Consideration for the Property.

(a) The Operating Partnership shall, in exchange for the Property, pay to the Contributor the total amount of consideration equal to $29,500,000.00 (the “Contributor Consideration”), which consists of (i) a cash payment in immediately available funds of $17,600,000.00 (the “Cash Consideration”), and (ii) the issuance to the Contributor of OP Units having a value of $11,900,000.00 (the “OP Unit Consideration”); provided that the Contributor Consideration may be adjusted as set forth in paragraph (b) of this Section 1.2. The Contributor shall, at Closing (as hereafter defined), use the Cash Consideration (in full) to retire any existing mortgage indebtedness (the “Existing Debt”) encumbering the Property (in addition to any other funds of Contributor necessary to retire such Existing Debt).

(b) The OP Unit Consideration payable to the Contributor shall be increased at the time of the Closing on a dollar-for-dollar basis to reflect any reduction, occurring between the date of this Agreement and the Closing, in the principal balance of that portion of the Existing Debt that is to be repaid at Closing by Contributor using the Cash Consideration.

(c) Intentionally Deleted.

(d) The issuance of the OP Units to the Contributor shall be evidenced by an amendment (the “Amendment”) to the agreement of limited partnership of the Operating Partnership (the “OP Partnership Agreement”).

At the Closing, all revenue and charges that are customarily prorated in transactions of this nature, including accrued rent currently due and payable, real and personal property taxes and other similar periodic charges payable or receivable with respect to the Property shall be prorated between the Contributor and the Operating Partnership, effective as of the Closing. Any such amounts that cannot be determined at Closing shall be prorated using reasonable estimates thereof. Thereafter, any over and under payments shall be subject to a true up as soon as commercially reasonable after Closing, provided that any estimated proration shall be final after twelve (12) months from Closing.

Section 1.4 Tax Treatment as Contribution.

The parties hereto intend and agree that, for federal income tax purposes, the contributions, transfers, conveyances and assignments effectuated pursuant to this Agreement shall be treated as contributions of the Property by the Contributor to the Operating Partnership in accordance with Section 721 of the Internal Revenue Code of 1986, as amended (the “Code”).

(e) Non-Foreign Status. The Contributor is not a foreign person for purposes of Section 1445(a) of the Code, and is, therefore, not subject to the provisions of the Code relating to the withholding of sales proceeds to foreign persons.

(f) Investment Purposes. The Contributor acknowledges its understanding that the OP Units to be acquired pursuant to the Agreement (and any Independence Realty Trust, Inc. (“Company”) common stock into which the OP Units may be exchanged in certain circumstances) are not being registered under the Securities Act of 1933, as amended, and the rules and regulations in effect thereunder (the “Act”) or any applicable state blue sky laws pursuant to a specific exemption or

6

exemptions therefrom, and the Operating Partnership’s reliance on such exemptions is predicated in part on the accuracy and completeness of the representations and warranties of the Contributor. In furtherance thereof, the Contributor represents and warrants to the Operating Partnership as follows:

(i) Investment. The Contributor is acquiring the OP Units solely for the Contributor’s own account for the purpose of investment and not as a nominee or agent for any other person and not with a view to, or for offer or sale in connection with, any distribution thereof. The Contributor agrees and acknowledges that it will not, directly or indirectly, offer, transfer, sell, assign, pledge, hypothecate or otherwise dispose of (each, a “Transfer”) any of the OP Units, unless (i) the Transfer is pursuant to an effective registration statement under the Act and qualification or other compliance under applicable blue sky or state securities laws, (ii) counsel for Contributor (which counsel shall be reasonably acceptable to the Operating Partnership) shall have furnished the Operating Partnership with an opinion, reasonably satisfactory in form and substance to the Operating Partnership, to the effect that no such registration is required because of the availability of an exemption from registration under the Act, or (iii) the Transfer is otherwise permitted by the OP Agreement. Notwithstanding the foregoing, no Transfer shall be made unless it is permitted under the OP Agreement.

(ii) Knowledge. The Contributor is knowledgeable, sophisticated and experienced in business and financial matters. Contributor fully understands the limitations on transfer imposed by the Federal securities laws and as described in the Agreement. The Contributor is able to bear the economic risk of holding the OP Units for an indefinite period and is able to afford the complete loss of Contributor’s investment in OP Units. Contributor has received and reviewed all information and documents about or pertaining to the Company, the Operating Partnership, the business and prospects of the Company and the Operating Partnership and the issuance of the OP Units as Contributor deems necessary or desirable, and has been given the opportunity to obtain any additional information or documents and to ask questions of the proposed management of the Operating Partnership and the Company and receive answers about such information and documents, the Company, the Operating Partnership, the business and prospects of the Company and the Operating Partnership and the OP Units that the Contributor deems necessary or desirable to evaluate the merits and risks related to the Contributor’s investment in the OP Units. The Contributor acknowledges that any such questions posed were answered to the Contributor’s satisfaction. The Contributor understands and has taken cognizance of all risk factors related to the issuance of the OP Units. The Contributor is relying upon its own independent analysis and assessment (including with respect to taxes), and the advice of the Contributor’s advisors (including tax advisors), and not upon that of the Company, the Operating Partnership or any of the Company’s or the Operating Partnership’s affiliates, for purposes of evaluating, entering into, and consummating the transactions contemplated by the Agreement.

(iii) Holding Period. The Contributor acknowledges that it has been advised that (A) unless the OP Units are subsequently registered under the Act or an exemption from such registration is available, such OP Units must be held (and the Contributor must continue to bear the economic risk of the investment in) for at least twelve (12) months and may (absent an effective registration statement or exemption from registration) have to be held indefinitely and the Contributor understands that the Operating Partnership has no obligation or intention to register the OP Units (or any Company common stock into which the OP Units may be exchanged), and (B) a notation shall be made in the appropriate records of the Operating Partnership (and the Company) indicating that the OP Units (and any Company common stock that might be exchanged therefor) are subject to restrictions on transfer.

7

(iv) Accredited Investor. The Contributor is an “accredited investor” (as such term is defined in Rule 501 (a) of Regulation D under the Act) and has a substantive pre-existing relationship with the Operating Partnership and the Company.

(g) No Brokers. Neither the Contributor nor any of the Contributor’s respective officers, directors or employees has employed or made any agreement with any broker, finder or similar agent or any person or firm that will result in the obligation of the Operating Partnership or any of its affiliates to pay any finder’s fee, brokerage fees or commissions or similar payment in connection with the transactions contemplated by the Agreement.

(h) Litigation. There is no pending litigation or proceeding, either judicial or administrative affecting the Contributor’s ability to consummate the transactions contemplated hereby or the Property other than eviction and other tenant disputes arising in the ordinary course of business. The Contributor knows of no outstanding order, writ, injunction or decree of any court, government, governmental entity or authority or arbitration against or affecting the Contributor or the Property which in any such case would impair Contributor’s ability to enter into and perform any or all of its obligations under the Agreement.

Section 3.3 Survival.

The representations and warranties of each of the Operating Partnership and the Contributor shall survive the closing for six (6) months following the Closing Date.

Section 3.4 Indemnification.

Notwithstanding anything contained herein to the contrary, no Indemnified Contributor Party shall have the right to receive or recover special, compensatory or punitive damages against the Operating Partnership and hereby waives any and all rights to receive such special, compensatory or punitive damages.

(b) The Contributor shall indemnify and hold harmless the Operating Partnership and the Operating Partnership’s partners, members, directors, officers, employees, agents, representatives, beneficiaries and affiliates (each, an “Indemnified OP Party”) from and against any and all Losses arising out of or relating to, asserted against, imposed upon or incurred by the Indemnified OP Party in connection with any breach of a representation or warranty of the Contributor contained in this Agreement. Notwithstanding anything contained herein to the contrary, no Indemnified OP Party shall have the right to receive or recover special, compensatory or punitive damages against the Contributor and hereby waives any and all rights to receive such special, compensatory or punitive damages.
