CONTRIBUTION AGREEMENT

THIS CONTRIBUTION AGREEMENT (including all exhibits, hereinafter referred to as this “Agreement”) is made and entered into as of July 31, 2004 by and between Digital Realty Trust, L.P., a Maryland limited partnership (the “Operating Partnership”), and Pacific-Bryan Partners, L.P., a Texas limited partnership (the “Contributor”).

RECITALS

A. The Contributor currently owns a ten percent (10%) limited partnership interest in ▇▇▇▇▇ Street Acquisition Partnership, L.P., a California limited partnership (the “Partnership”), which is the direct fee interest holder in the property referred to as Univision Tower, located at ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇ (the “Participating Property” or “Property”). As used herein, “Partnership Agreement” means the partnership agreement under which the Partnership was formed (including all amendments or restatements).

B. The Operating Partnership desires to consolidate the ownership of a portfolio of properties through a series of transactions (the “Formation Transactions”) whereby the Operating Partnership will acquire direct or indirect interests in such properties, including the Participating Property, by acquiring direct interests in such properties (the “Property Interests”) or, directly or indirectly, some or all of the interests in certain limited partnerships, certain limited liability companies and certain other entities, including the Partnership (collectively, the “Participating Partnerships”), which currently own directly or indirectly the Participating Property, or a combination of the foregoing.

C. The Formation Transactions relate to the proposed initial public offering (the “Public Offering”) of the common stock of Digital Realty Trust, Inc., a Maryland corporation (the “Company”), which will operate as a self-administered and self-managed real estate investment trust (“REIT”) within the meaning of Section 856 of the Internal Revenue Code of 1986, as amended (the “Code”) and which is the sole general partner of the Operating Partnership.

D. The owners of the Property Interests and the partners and members of the Participating Partnerships will either transfer their unencumbered Property Interests or unencumbered interests in the Participating Partnerships, as applicable, to the Operating Partnership in exchange for units of limited partnership interest (“Partnership Units”) in the Operating Partnership.

E. The Contributor desires to, and the Operating Partnership desires the Contributor to, contribute to the Operating Partnership, all of its right, title and interest, free and clear of all Liens (as defined in Exhibit C), as a partner in the Partnership, including, without limitation, all of its voting rights and interests in the capital, profits and losses of the Partnership or any property distributable therefrom, constituting all of its interests in and to the Partnership (such right, title and interest in and to the Partnership are hereinafter collectively referred to as the “Partnership Interest”), in exchange for Partnership Units, on the terms and subject to the conditions set forth herein.

F. The Contributor acknowledges that the Operating Partnership may decide that, rather than acquiring the Partnership Interest by direct transfer, it is more desirable for the Operating Partnership to acquire the Property by a direct contribution of the Property from the Partnership (a “Direct Contribution”), or by a merger of the Partnership or a subsidiary thereof with and into the Company, the Operating Partnership or an affiliate of either of them (a “Merger”), or to divide the Partnership or a subsidiary thereof into more than one partnership to facilitate the Formation Transactions (a “Division”); and the Contributor desires to give the Operating Partnership the right, in the Operating Partnership’s sole discretion, to engage in any Direct Contribution, Merger or Division on the terms and conditions

described herein (provided, however, such alternative transaction may involve the issuance of an equivalent number of shares of Common Stock of the Company instead of Partnership Units) without the need to seek any further consent or action of the Contributor, and will give hereby an irrevocable power of attorney as set forth in Article 6 hereof and irrevocable consents as set forth in Section 5.1 hereof.

NOW, THEREFORE, for and in consideration of the foregoing premises, and the mutual undertakings set forth below, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

TERMS OF AGREEMENT

ARTICLE 1.

CONTRIBUTION OF PARTNERSHIP INTEREST

AND EXCHANGE FOR PARTNERSHIP UNITS

Section 1.1 Contribution of Partnership Interest. Effective as of the Closing (as defined in Section 2.2 herein) and subject to the terms and conditions contained in this Agreement, the Contributor shall contribute, transfer, assign, convey and deliver to the Operating Partnership, absolutely and unconditionally, and free and clear of all Liens, all of its right, title and interest to the Partnership Interest, including all of the Contributor’s rights and interest to the Partnership and all rights to indemnification in favor of the Contributor under the agreements pursuant to which the Contributor or its affiliates acquired the Partnership Interest transferred pursuant to this Agreement. The contribution of the Contributor’s Partnership Interest shall be evidenced by a Contribution and Assumption Agreement in substantially the form of Exhibit A attached hereto. The parties shall take such additional actions and execute such additional documentation as may be required by the Partnership Agreement and the Amended and Restated Agreement of Limited Partnership of the Operating Partnership (the “OP Agreement”) or as reasonably requested in the reasonable judgment of counsel by the Operating Partnership in order to effect the transactions contemplated hereby.

Section 1.2 Consideration and Exchange of Partnership Units. Subject to Section 1.3, the Operating Partnership shall, in exchange for the Partnership Interest, transfer to the Contributor a total of 244,704 Partnership Units (the “Total Consideration”) as such Total Consideration may be adjusted pursuant to Exhibit B attached hereto. The transfer of the Partnership Units to the Contributor shall be evidenced by either an amendment (the “Amendment”) to the OP Agreement or by certificates relating to such Partnership Units (the “Certificates”) in either case, as determined by the Operating Partnership, in such form as shall be reasonably acceptable to the Contributor. The parties shall take such additional actions and execute such additional documentation as may be required by the relevant Partnership Agreements and the OP Agreement in order to effect the transactions contemplated hereby.

Section 1.3 Adjusted Consideration. The Operating Partnership reserves the right not to acquire the Partnership Interest, if in good faith the Operating Partnership determines that the ownership of the underlying Property would be inappropriate for the Operating Partnership. The parties hereby agree that, in such event, the Contributor will not receive the Total Consideration, and the contribution of the Partnership Interest set forth in Section 1.1 shall be null and void and of no further effect.

The risk of loss relating to the Contributor’s Partnership Interest and the underlying Property prior to Closing shall be borne by the Contributor. If, prior to the Closing, any Property is partially or totally destroyed or damaged by fire or other casualty, or is taken by eminent domain or through condemnation proceedings, then the Operating Partnership may, at its option, determine not to acquire the particular interest in the Partnership that directly or indirectly owns the Property that has been partially or totally destroyed, damaged or taken. After the occurrence of any such casualty or condemnation affecting a Property, the Operating Partnership may also, at its option, elect to (a) acquire the Contributor’s particular interest in the Partnership that directly or indirectly owns the affected Property, (b) direct the Contributor to pay or cause to be paid to the Operating Partnership any sums collected by the Contributor, if any, under any policies of insurance, if any, or award proceeds relating to such casualty or condemnation, if any, and otherwise assign to the Operating Partnership all rights of the Contributor to collect such sums as may then be uncollected, and/or (c) to the extent available to the Contributor, adjust or settle any insurance claim or condemnation proceeding. Under such circumstances, the Contributor’s Total Consideration shall be reduced by its pro rata share of the amount of any deductibles under the applicable insurance policies or award (based on its ownership interest in the underlying asset) to the extent such deductible is paid by the Operating Partnership. Insurance on the transferred Partnership Interest shall be assigned to the Operating Partnership at the Closing.

Section 1.4 Treatment as Contribution. The transfer, assignment and exchange of the Partnership Interest effectuated pursuant to this Agreement shall constitute a “Capital Contribution” to the Operating Partnership pursuant to Article 4 of the OP Agreement and is intended to be governed by Section 721(a) of the Code, and the Contributor (including any transferor in connection with a Direct Contribution, if any, as provided hereunder) hereby consents to such treatment.

Section 1.5 Allocation of Total Consideration. The Total Consideration shall be allocated in a manner reasonably agreed upon by the Operating Partnership and the Contributor. The Operating Partnership and the Contributor agree to (i) be bound by the allocation, (ii) act in accordance with the allocation in the preparation of financial statements and filing of all tax returns and in the course of any tax audit, tax review or tax litigation relating thereto and (iii) take no position and cause their affiliates to take no position inconsistent with the allocation for income tax purposes.

Section 1.6 Term of Agreement. If the Closing does not occur by March 31, 2005 (the “Termination Date”), this Agreement shall be deemed terminated and shall be of no further force and effect and neither the Operating Partnership nor the Contributor shall have any further obligations hereunder except as specifically set forth herein.

Section 1.7 Final Year Allocations. To the extent the Partnership Agreement does not provide for final year tax allocations, if applicable, the parties hereto agree to use the “interim closing of the books” method as provided in Section 706 of the Code (or another method if agreed to by such parties) to allocate income and loss for the year in which the Formation Transactions close.

ARTICLE 2.

(ii) Except as otherwise disclosed in the Disclosure Schedule, mortgage, pledge or encumber all or any portion of its Partnership Interest.

(a) As of the Closing, the Contributor waives and relinquishes all rights and benefits otherwise afforded to the Contributor under the Partnership Agreement including, without limitation, any rights of appraisal, rights of first offer or first refusal, buy/sell agreements, and any right to consent to or approve of the sale or contribution by the other partners or members of the Partnership of their Partnership Interest to the Operating Partnership, the Company or any direct or indirect subsidiary thereof and any and all notice provisions related thereto. The Contributor acknowledges that the agreements contained herein and the transactions contemplated hereby and any actions taken in contemplation of the transactions contemplated hereby may conflict with, and may not have been contemplated by, the Partnership Agreement or other agreements among one or more holders of the Partnership Interest or one or more of the partners of the Partnership. With respect to the Partnership and the Property, the Contributor expressly gives all Consents (and any consents necessary to authorize the proper parties in interest to give all Consents) and Waivers it is entitled to give that are necessary or desirable to (i) facilitate any Conveyance Action (as hereinafter defined) relating to the Partnership or Property, (ii) cause the Partnership to have authority to transfer the Partnership Interest or Property to the Operating Partnership, and (iii) receive Partnership Units

In addition, if the transactions contemplated hereby occur, this Agreement shall be deemed to be an amendment to any Partnership Agreement to the extent the terms herein conflict with the terms thereof, including without limitation, terms with respect to allocations, distributions and the like. In the event the transactions contemplated by this Agreement do not occur, nothing in this Agreement shall be deemed to be or construed as an amendment or modification of, or commitment of any kind to amend or modify, the Partnership Agreements, which shall remain in full force and effect without modification.

(b) As used herein, the term “Conveyance Action” means, with respect to the Partnership, (i) the transfer, conveyance or agreement to convey by a partner thereof or by any holder of an indirect interest therein (whether or not such partner or holder is the Contributor hereunder) directly, by Direct Contribution, Merger, Division or otherwise of its direct or indirect interest in the Partnership or Property to the Operating Partnership or the Company or (ii) the entering into by any such partner or holder any agreement relating to (x) the formation of the Operating Partnership or the Company, or (y) the direct or indirect acquisition by the Operating Partnership or the Company of any such direct or indirect interest or (iii) the taking by any such partner or holder of any action necessary or desirable to facilitate any of the foregoing, including, without limitation, the following (provided that the same are taken in furtherance of the foregoing): any sale or distribution to any Person of a direct or indirect interest in the Partnership or Property, the entering into any agreement with any Person that grants to such Person the right to purchase a direct or indirect interest in the Partnership or Property, and the giving of the Consents and Waivers contained in this Section or consents or waivers similar thereto in form or purpose.

(d) As used herein, the term “Waivers” means, with respect to the Partnership or Property, the waiving of any and all rights that the Contributor may have with respect to, and (to the extent controlled by the Contributor) that any such other Person may have with respect to, or that may accrue to the Contributor or such other controlled Person upon the occurrence of, a Conveyance Action relating to the Partnership or Property, including, but not limited to, the following rights: rights of notice, rights to response periods, rights to purchase the direct or indirect interests of another partner in the Partnership or Property or to sell the Contributor’s or other Person’s direct or indirect interest therein to another partner, rights to sell the Contributor’s or other Person’s direct or indirect interest therein at a price other than as provided herein, or rights to prohibit, limit, invalidate, otherwise restrict or impair any such Conveyance Action or to cause a termination or dissolution of the Partnership because of such Conveyance Action.

covenants that the Contributor will take no action to enjoin, or seek damages resulting from, any Conveyance Action by any holder of a direct or indirect interest in the Partnership or the Property.

(e) The Waivers and Consents contained in this Section shall terminate upon the termination of this Agreement, except as to transactions completed hereunder prior to termination.

ARTICLE 6.

POWER OF ATTORNEY

Section 6.1 Grant of Power of Attorney. The Contributor hereby irrevocably appoints the Operating Partnership (or its designee) and any successor thereof from time to time (such Operating Partnership or designee or any such successor of any of them acting in his, her or its capacity as attorney-in-fact pursuant hereto, the “Attorney-In-Fact”) as the true and lawful attorney-in-fact and agent of the Contributor, to act in the name, place and stead of the Contributor to make, execute, acknowledge and deliver all such other deeds (including grant deeds if applicable), assignments, contracts, orders, receipts, notices, requests, instructions, certificates, consents, letters and other writings (including without limitation the execution of any Closing Documents or other documents relating to the acquisition by the Operating Partnership of the Contributor’s Partnership Interest, including, but not limited to, any registration rights agreements and any lock-up agreements), to provide information to the Securities and Exchange Commission and others about the transactions contemplated hereby and, in general, to do all things and to take all actions which the Attorney-in-Fact in its sole discretion may consider necessary or proper in connection with or to carry out the transactions contemplated by this Agreement, as fully as could the Contributor if personally present and acting (the “Power of Attorney”). Concurrently with the execution of this Agreement, each Contributor shall provide a Power of Attorney fully executed and duly acknowledged in the form attached hereto as Exhibit D.

The Power of Attorney and all authority granted hereby shall be coupled with an interest and therefore shall be irrevocable and shall not be terminated by any act of the Contributor, by operation of law or by the occurrence of any other event or events, and if any other such act or events shall occur before the completion of the transactions contemplated by this Agreement, the Attorney-in-Fact shall nevertheless be authorized and directed to complete all such transactions as if such other act or events had not occurred and regardless of notice thereof. The Contributor agrees that, at the request of Operating Partnership it will promptly execute and deliver to the Operating Partnership a separate power of attorney and proxy on the same terms set forth in this Article 6, such execution to be witnessed and notarized, and in recordable form (if necessary). The Contributor hereby authorizes the reliance of third parties on each of the Power of Attorney.

The Contributor acknowledges that the Operating Partnership has, and any designee or successor thereof acting as Attorney-in-Fact may have, an economic interest in the transactions contemplated by this Agreement.

Section 6.2 Limitation on Liability. It is understood that by the grant of Power of Attorney in Section 6.1, the Attorney-in-Fact assumes no responsibility or liability to any person by virtue of the Power of Attorney granted by the Contributor hereby. The Attorney-in-Fact as such attorney-in-fact by virtue of the grant in Section 6.1, makes no representations with respect to and shall have no responsibility for the Formation Transactions or the Public Offering, or the acquisition of the Partnership Interest and shall not be liable to the Contributor for any error or judgment or for any act done or omitted or for any mistake of fact or law

except for its own gross negligence or bad faith, or breach of this Agreement or the terms of its power of attorney provided for herein. The Contributor agrees to indemnify the Attorney-in-Fact for and to hold the Attorney-in-Fact harmless against any loss, claim, damage or liability (including reasonably attorneys’ fees) incurred on its part arising out of or in connection with it acting as the Attorney-in-Fact under the Power of Attorney created by the Contributor hereby, as well as the cost and expense of investigating and defending against any such loss, claim, damage or liability, except to the extent such loss, claim, damage or liability is due to its own gross negligence or bad faith, or breach of this Agreement or the terms of its power of attorney provided for herein. The Contributor agrees that the Attorney-in-Fact may consult with counsel of its own choice (who may be counsel for Operating Partnership or its successors or affiliates), and it shall have full and complete authorization and protection for any action taken or suffered by it hereunder in good faith and in accordance with the opinion of such counsel. It is understood that the Attorney-in-Fact may, without breaching any express or implied obligation to the Contributor hereunder, release, amend or modify any other power of attorney granted by any other person under any related agreement.

Section 6.3 Ratification; Third Party Reliance. The Contributor hereby ratifies and confirms that the Attorney-in-Fact shall lawfully do or cause to be done by virtue of the exercise of the powers granted unto it by the Contributor under this Article 6, and the Contributor authorizes the reliance of third parties on this Power of Attorney and waives its rights, if any, as against any such third party for its reliance hereon.

ARTICLE 7.

MISCELLANEOUS

Section 7.1 Further Assurances. The Contributor and the Operating Partnership shall take such other actions and execute such additional documents following the Closing as the other may reasonably request in order to effect the transactions contemplated hereby.

Section 7.2 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

Section 7.3 Governing Law. This Agreement shall be governed by the internal laws of the State of California, without regard to the choice of laws provisions thereof.

Section 7.4 Amendment; Waiver. Any amendment hereto shall be in writing and signed by all parties hereto. No waiver of any provisions of this Agreement shall be valid unless in writing and signed by the party against whom enforcement is sought.

Section 7.5 Entire Agreement. This Agreement, the exhibits and all related schedules hereto and the agreements referred to in Section 2.3 hereof constitute the entire agreement and supersede conflicting provisions set

forth in all other prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof and thereof, as the case may be. Exhibit C is incorporated in this Agreement by reference in its entirety, such that reference to this “Agreement” shall automatically include Exhibit C, and is subject to all of the provisions of this Article 7.

Section 7.6 Assignability. This Agreement shall be binding upon, and shall be enforceable by and inure to the benefit of, the parties hereto and their respective heirs, legal representatives, successors and assigns; provided, however, that this Agreement may not be assigned (except by operation of law) by any party without the prior written consent of the other parties, and any attempted assignment without such consent shall be void and of no effect, except that the Operating Partnership, may assign its rights and obligations hereunder to an affiliate.

Section 7.7 Titles. The titles and captions of the Articles, Sections and paragraphs of this Agreement are included for convenience of reference only and shall have no effect on the construction or meaning of this Agreement.

Section 7.8 Third Party Beneficiary. Except as may be expressly provided or incorporated by reference herein, including, without limitation, the indemnification provisions hereof, no provision of this Agreement is intended, nor shall it be interpreted, to provide or create any third party beneficiary rights or any other rights of any kind in any customer, affiliate, stockholder, partner, member, director, officer or employee of any party hereto or any other person or entity.

Section 7.9 Severability. If any provision of this Agreement, or the application thereof, is for any reason held to any extent to be invalid or unenforceable, the remainder of this Agreement and application of such provision to other persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of the void or unenforceable provision and to execute any amendment, consent or agreement deemed necessary or desirable by the Operating Partnership to effect such replacement.

Section 7.10 Reliance. Each party to this Agreement acknowledges and agrees that it is not relying on tax advice or other advice from the other party to this Agreement, and that it has or will consult with its own advisors.

Section 7.11 Survival. It is the express intention and agreement of the parties hereto that the representations, warranties and covenants of the Contributor and the Operating Partnership set forth in this Agreement shall survive the consummation of the transactions contemplated hereby. The provisions of this Agreement that contemplate performance after the Closing and the obligations of the parties not fully

performed at the Closing shall survive the Closing and shall not be deemed to be merged into or waived by the instruments of Closing.

Section 7.12 Notice. Any notice to be given hereunder by any party to the other shall be given in writing by either (i) personal delivery, (ii) registered or certified mail, postage prepaid, return receipt requested, or (iii) facsimile transmission (provided such facsimile is followed by an original of such notice by mail or personal delivery as provided herein), and any such notice shall be deemed communicated as of the date of delivery (including delivery by overnight courier, certified mail or facsimile).

Section 7.13 Equitable Remedies. Each Contributor agrees that irreparable damage would occur to the Operating Partnership in the event that any of the provisions of this Agreement were not performed in accordance with the specific terms hereof or were otherwise breached. It is accordingly agreed that the Operating Partnership shall be entitled to an injunction or injunctions to prevent breaches of this Agreement by any Contributor and to enforce specifically the terms and provisions hereof in any federal or state court located in California (as to which the parties agree to submit to jurisdiction for the purpose of such

action), this being in addition to any other remedy to which the Operating Partnership is entitled under this Agreement.

Section 7.14 Dispute Resolution. The parties hereby agree that, in order to obtain prompt and expeditious resolution of any disputes under this Agreement, each claim, dispute or controversy of whatever nature, arising out of, in connection with, or in relation to the interpretation, performance or breach of this Agreement (or any other agreement contemplated by or related to this Agreement or any other agreement between the parties), including without limitation any claim based on contract, tort or statute, or the arbitrability of any claim hereunder (an “Arbitrable Claim”), shall, subject to Section 7.13 above, be settled by final and binding arbitration conducted in San Francisco, California. The arbitrability of any Arbitrable Claims under this Agreement shall be resolved in accordance with a two-step dispute resolution process administered by Judicial Arbitration & Mediation Services, Inc. (“JAMS”) involving, first, mediation before a retired judge from the JAMS panel, followed, if necessary, by final and binding arbitration before the same, or if requested by either party, another JAMS panelist. Such dispute resolution process shall be confidential and shall be conducted in accordance with California Evidence Code Section 1119.

(i) Mediation. In the event any Arbitrable Claim is not resolved by an informal negotiation between the parties within fifteen (15) days after either party receives written notice that a Arbitrable Claim exists, the matter shall be referred to the San Francisco, California office of JAMS, or any other office agreed to by the parties, for an informal, non-binding mediation consisting of one or more conferences between the parties in which a retired judge will seek to guide the parties to a resolution of the Arbitrable Claims. The parties shall select a mutually acceptable neutral arbitrator from among the JAMS panel of mediators. In the event the parties cannot agree on a mediator, the Administrator of JAMS will appoint a mediator. The mediation process shall continue until the earliest to occur of the following: (i) the Arbitrable Claims are resolved, (ii) the mediator makes a finding that there is no possibility of resolution through mediation, or (iii) thirty (30) days have elapsed since the Arbitrable Claim was first scheduled for mediation.

(ii) Arbitration. Should any Arbitrable Claims remain after the completion of the mediation process described above, the parties agree to submit all remaining Arbitrable Claims to final and binding arbitration administered by JAMS in accordance with the then existing JAMS Arbitration Rules. Neither party nor the arbitrator shall disclose the existence, content, or results of any arbitration hereunder without the prior written consent of all parties. Except as provided herein, the California Arbitration Act shall govern the interpretation, enforcement and all proceedings pursuant to this subparagraph. The arbitrator is without jurisdiction to apply any substantive law other than the laws selected or otherwise expressly provided in this Agreement. The arbitrator shall render an award and a written, reasoned opinion in support thereof. Such award may include reasonable attorneys’ fees to the prevailing party. Judgment upon the award may be entered in any court having jurisdiction thereof.

(iii) Costs. The arbitrator may, in its discretion, allocate the costs, fees and expenses incurred by the parties, as well as the fees and expenses of the mediator or arbitrator and the costs of the facility for the hearing, among the parties on the basis of fault.

(iv) Survivability. This dispute resolution process shall survive the termination of this Agreement. The parties expressly acknowledge that by signing this Agreement, they are giving up their respective right to a jury trial.

To the extent that, on the Determination Date, the Operating Partnership’s good faith determination of the amount of the outstanding principal balance of existing indebtedness to be outstanding immediately prior to the Closing Date with respect to the Property is greater than or less than $56,638,855, the number of Partnership Units delivered to the Contributor pursuant to Section 1.2 of the Agreement shall be decreased or increased, as the case may be, by the number of Partnership Units equal to Ten Percent (10%) of such increase or decrease in existing indebtedness divided by Twenty Dollars ($20.00), rounded down to the nearest whole Partnership Unit.

With respect to this Exhibit B, the “Determination Date” shall mean a date, designated by the Operating Partnership, no more than five business days nor less than one business day prior to the “Subject to Completion Date” date set forth on the preliminary prospectus printed and distributed to potential investors in connection with the marketing of the Public Offering, provided, however, that if a subsequent preliminary prospectus is thereafter printed and recirculated to potential investors, then the Determination Date shall mean the date of such subsequent preliminary prospectus.

ARTICLE 2 — REPRESENTATIONS AND WARRANTIES OF CONTRIBUTOR

Except as set forth in the Disclosure Schedule, the Contributor represents and warrants to the Operating Partnership as set forth below in this Article 2, which representations and warranties are true and correct as of the date hereof and will (except to the extent expressly relating to a specified date) be true and correct as of the date of Closing:

2.1 Organization; Authority; Qualification. The Contributor is duly formed, validly existing and in good standing under the laws of the jurisdiction of its formation. The Contributor has all requisite power and authority to enter into the Agreement, each agreement contemplated hereby and to carry out the transactions contemplated hereby and thereby, and to own, lease or operate its property and to carry on its business as presently conducted and, to the extent required under applicable law, is qualified to do business and is in good standing in each jurisdiction in which the nature of its business or the character of its property make such qualification necessary.

2.2 Due Authorization. The execution, delivery and performance of the Agreement by the Contributor has been duly and validly authorized by all necessary action of the Contributor. The Agreement and each agreement, document and instrument executed and delivered by or on behalf of the Contributor pursuant to the Agreement constitutes, or when executed and delivered will constitute, the legal, valid and binding obligation of the Contributor, each enforceable against the Contributor in accordance with its terms, as such enforceability may be limited by bankruptcy or the application of equitable principles.

2.3 Consents and Approvals. Except as shall have been satisfied prior to the Closing Date and as set forth in Schedule 2.3 to the Disclosure Schedule, as of the date hereof, no consent, waiver, approval or authorization of any third party or governmental authority or agency is required to be obtained by the Contributor in connection with the execution, delivery and performance of the Agreement

Exhibit C-2

and the transactions contemplated hereby, except for those consents, waivers, approvals or authorizations, the failure of which to obtain would not have a material adverse effect on the assets, business, financial condition and results of operation of the Company, the Operating Partnership and their subsidiaries, taken as a whole (a “Material Adverse Effect”).

2.4 Ownership of the Partnership Interest. The Partnership Interest constitutes all of the issued and outstanding interests in the Partnership owned by the Contributor. Except as set forth in Schedule 2.4 to the Disclosure Schedule, the Contributor is the sole owner of the Partnership Interest, beneficially and of record, free and clear of any Liens of any nature (other than the Permitted Liens) and has full power and authority to convey the Partnership Interest, free and clear of any Liens (other than the Permitted Liens), and, upon delivery of consideration for the Partnership Interest, the Operating Partnership will acquire good and marketable title thereto, free and clear of any Liens (other than the Permitted Liens and any liens arising through the Operating Partnership). Except as may be set forth in the Partnership Agreement, there are no rights to purchase, subscriptions, warrants, options, conversion rights or preemptive rights relating to the Partnership Interest.

2.5 No Violation. Except as shall have been cured to the satisfaction of the Operating Partnership, consented to or waived in writing by the Operating Partnership prior to the Closing Date or as set forth in Schedule 2.5 to the Disclosure Schedule, none of the execution, delivery or performance of the Agreement, any agreement contemplated thereby and the transactions contemplated hereby and thereby does or will, with or without the giving of notice, lapse of time, or both, violate, conflict with, result in a breach of, or constitute a default under or give to others any right of termination, acceleration, cancellation or other right adverse to the Contributor or the Operating Partnership of (A) the organizational documents, including the operating agreement, if any, of the Contributor, (B) any agreement, document or instrument to which the Contributor is a party or by which the Contributor or the Partnership Interest are bound or (C) any term or provision of any judgment, order, writ, injunction, or decree, or require any approval, consent or waiver of, or make any filing with, any person or governmental or regulatory authority or foreign, federal, state, local or other law binding on the Contributor or by which the Contributor or any of its assets or properties are bound or subject; provided in the case of (B) and (C) above, unless any such violation, conflict, breach or default would not have a Material Adverse Effect.

2.6 Non-Foreign Status. The Contributor is a United States person (as defined in Section 7701(a)(30) of the Code), and is, therefore, not subject to the provisions of the Code relating to the withholding of sales proceeds to foreign persons, and is not subject to any state withholding requirements. The Contributor will provide affidavits at the Closing to this effect as provided for in Section 2.3(g) of the Agreement.

2.7 Withholding. The Contributor shall execute at Closing such certificates or affidavits reasonably necessary to document the inapplicability of any United States federal or state withholding provisions, including without limitation those referred to in Section 2.6 above. If the Contributor fails to provide such certificates or affidavits, the Operating Partnership may withhold a portion of any payments otherwise to be made to the Contributor as required by the Code or applicable state law.

2.8 Investment Purposes. The Contributor acknowledges its understanding that the offering and issuance of the Partnership Units to be acquired pursuant to the Agreement are intended to be exempt from registration under the Securities Act of 1933, as amended and the rules and regulations in effect thereunder (the “Act”) and that the Operating Partnership’s reliance on such exemptions is predicated in part on the accuracy and completeness of the representations and warranties of the

Exhibit C-3

Contributor contained herein. In furtherance thereof, the Contributor represents and warrants to the Company as follows:

2.8.1 Investment. The Contributor is acquiring the Partnership Units solely for its 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 of any thereof. The Contributor agrees and acknowledges that it will not, directly or indirectly, offer, transfer, sell, assign, pledge, hypothecate or otherwise dispose of (hereinafter, “Transfer”) any of the Partnership 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, or (ii) counsel for the 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 and qualification or other compliance under applicable blue sky or state securities laws. The term “Transfer” shall not include any redemption of the Partnership Units or exchange of the Partnership Units for REIT Shares pursuant to Section 8.6 of the OP Agreement. Notwithstanding the foregoing, no Transfer shall be made unless it is permitted under the OP Agreement.

2.8.2 Knowledge. The Contributor is knowledgeable, sophisticated and experienced in business and financial matters and 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 Partnership Units for an indefinite period and is able to afford the complete loss of its investment in the Partnership Units; the Contributor has received and reviewed all information and documents (including the private placement memorandum delivered by the Operating Partnership) 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 Partnership Units as the Contributor deems necessary or desirable, has had cash flow and operations data for the Property made available by the Operating Partnership upon request and has been given the opportunity to obtain any additional information or documents and to ask questions and receive answers about such information and documents, the Company, the Operating Partnership, the Property, the business and prospects of the Company and the Operating Partnership and the Partnership Units which the Contributor deems necessary or desirable to evaluate the merits and risks related to its investment in the Partnership Units and to conduct its own independent valuation of the Properties.

2.8.3 Holding Period. The Contributor acknowledges that it has been advised that (i) the Partnership Units must be held for twelve (12) months and may (absent an effective registration statement or exemption from registration under the Act) have to be held indefinitely thereafter, and the Contributor must continue to bear the economic risk of the investment in the Partnership Units (and any Common Stock that might be exchanged therefor), unless they are subsequently registered under the Act or an exemption from such registration is available (it being understood that the Operating Partnership has no intention of so registering the Partnership Units), (ii) a restrictive legend in the form hereafter set forth shall be placed on the certificates representing the Partnership Units (and any Common Stock that might be exchanged therefor), and (iii) a notation shall be made in the appropriate records of the Operating Partnership (and the Company) indicating that the Partnership Units (and any Common Stock that might be exchanged therefor) are subject to restrictions on transfer.

2.8.4 Accredited Investor. The Contributor is an “accredited investor” (as such term is defined in Rule 501 (a) of Regulation D under the Act). The Contributor has previously provided the Operating Partnership with a duly executed Accredited Investor Questionnaire. No event or

Exhibit C-4

circumstance has occurred since delivery of such Questionnaire to make the statements contained therein false or misleading.

2.8.5 Legend. Each certificate representing the Partnership Units (and any Common Stock that might be exchanged therefor) shall bear the following legend:

THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION, UNLESS THE TRANSFEROR DELIVERS TO THE COMPANY AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY, TO THE EFFECT THAT THE PROPOSED SALE, TRANSFER OR OTHER DISPOSITION MAY BE EFFECTED WITHOUT REGISTRATION UNDER THE ACT AND UNDER APPLICABLE STATE SECURITIES OR “BLUE SKY” LAWS;

In addition, the Common Stock for which the Partnership Units may, in certain circumstances, be exchanged shall also bear a legend which generally provides the following:

THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON BENEFICIAL AND CONSTRUCTIVE OWNERSHIP AND TRANSFER FOR THE PURPOSE OF THE CORPORATION’S MAINTENANCE OF ITS STATUS AS A REAL ESTATE INVESTMENT TRUST (“REIT”) UNDER THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”). SUBJECT TO CERTAIN FURTHER RESTRICTIONS AND EXCEPT AS EXPRESSLY PROVIDED IN THE CORPORATION’S ARTICLES OF AMENDMENT AND RESTATEMENT, (i) NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF CAPITAL STOCK OF THE CORPORATION IN EXCESS OF 9.8% OF THE VALUE OF THE TOTAL OUTSTANDING SHARES OF CAPITAL STOCK OF THE CORPORATION AND NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF THE CORPORATION’S COMMON STOCK IN EXCESS OF 9.8% (BY VALUE OR BY NUMBER OF SHARES, WHICHEVER IS MORE RESTRICTIVE) OF THE OUTSTANDING COMMON STOCK OF THE CORPORATION; (ii) NO PERSON MAY BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF CAPITAL STOCK THAT WOULD RESULT IN THE CORPORATION BEING “CLOSELY HELD” UNDER SECTION 856(h) OF THE CODE OR OTHERWISE CAUSE THE CORPORATION TO FAIL TO QUALIFY AS A REIT; AND (iii) NO PERSON MAY TRANSFER SHARES OF CAPITAL STOCK IF SUCH TRANSFER WOULD RESULT IN THE CAPITAL STOCK OF THE CORPORATION BEING OWNED BY FEWER THAN 100 PERSONS. ANY PERSON WHO BENEFICIALLY OR CONSTRUCTIVELY OWNS OR ATTEMPTS TO BENEFICIALLY OR CONSTRUCTIVELY OWN SHARES OF CAPITAL STOCK IN VIOLATION OF THE ABOVE LIMITATIONS MUST IMMEDIATELY NOTIFY THE CORPORATION. IF ANY OF THE RESTRICTIONS ON TRANSFER OR OWNERSHIP SET FORTH IN (i) OR (ii) IS VIOLATED, THE SHARES OF COMMON STOCK REPRESENTED HEREBY WILL BE AUTOMATICALLY TRANSFERRED TO THE TRUSTEE OF A TRUST FOR THE BENEFIT OF ONE OR MORE CHARITABLE BENEFICIARIES, AND ANY TRANSFER THAT WOULD RESULT IN THE CAPITAL STOCK OF THE CORPORATION BEING OWNED BY FEWER THAN 100 PERSONS SHALL BE VOID AB INITIO. IN ADDITION, THE CORPORATION MAY REDEEM SHARES UPON THE TERMS AND CONDITIONS SPECIFIED BY THE BOARD OF DIRECTORS IN ITS SOLE DISCRETION IF THE BOARD OF DIRECTORS DETERMINES THAT OWNERSHIP OR A TRANSFER OR OTHER EVENT MAY VIOLATE THE RESTRICTIONS DESCRIBED ABOVE. FURTHERMORE, UPON THE OCCURRENCE

Exhibit C-5

OF CERTAIN EVENTS, ATTEMPTED TRANSFERS IN VIOLATION OF THE RESTRICTIONS DESCRIBED ABOVE MAY BE VOID AB INITIO. ALL TERMS IN THIS LEGEND THAT ARE DEFINED IN THE CHARTER OF THE CORPORATION SHALL HAVE THE MEANINGS ASCRIBED TO THEM IN THE CHARTER OF THE CORPORATION, AS THE SAME MAY BE AMENDED FROM TIME TO TIME, A COPY OF WHICH, INCLUDING THE RESTRICTIONS ON TRANSFER AND OWNERSHIP, WILL BE FURNISHED TO EACH HOLDER OF SHARES OF COMMON STOCK ON REQUEST AND WITHOUT CHARGE. REQUESTS FOR SUCH A COPY MAY BE DIRECTED TO THE SECRETARY OF THE CORPORATION AT ITS PRINCIPAL OFFICE.

2.9 No Brokers. No Contributor nor any of the Contributor’s respective officers, directors or employees, to the extent applicable, has employed or made any agreement with any broker, finder or similar agent or any person or firm which 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.

2.10 Solvency. Assuming the accuracy of the Operating Partnership’s representations and warranties, the Contributor will be solvent immediately following the transfer of the Partnership Interest to the Operating Partnership.

2.11 Litigation. There is no Action, litigation, claim or other proceeding, either judicial or administrative (including, without limitation, any governmental action or proceeding), pending or, to Contributor’s Knowledge, threatened in the last twelve months, affecting all or any portion of the Contributor’s Partnership Interest or the Contributor’s ability to consummate the transactions contemplated hereby. Contributor is not bound by any outstanding order, writ, injunction or decree of any court, Governmental Entity or arbitration against or affecting all or any portion of its Partnership Interest which in any such case would impair the Contributor ability to enter into and perform all of its obligations under the Agreement or would have a Material Adverse Effect.

2.12 Exclusive Representations. Except as set forth above in this Exhibit C, the Contributor makes no representation or warranty of any kind, express or implied, in connection with the Partnership Interest and the Operating Partnership acknowledges that it has not relied upon any other such representation or warranty. Except as set forth in Section 3.2(e) of the Agreement, the Contributor acknowledges that no representation or warranty has been made by the Company or the Operating Partnership with respect to the legal and tax consequences of the transfer of the Contributor’s Partnership Interest to the Operating Partnership and the receipt of Partnership Units, as consideration therefor. The Contributor further represents and warrants that it has not relied on the Operating Partnership or its affiliates, representatives, counsel or other advisors and its respective representatives for legal or tax advice and the Contributor acknowledges that it has not relied upon any other such representation or warranty.

Exhibit C-6

ARTICLE 3 — INDEMNIFICATION

3.1 Survival Of Representations And Warranties; Remedy For Breach.

(a) Subject to Section 3.5 of this Exhibit C, all representations and warranties contained in this Exhibit C (as qualified by the Disclosure Schedule) or in any Schedule or certificate delivered pursuant hereto shall survive the Closing.

(b) Notwithstanding anything to the contrary in the Agreement or this Exhibit C, the Contributor shall not be liable under this Exhibit C or the Agreement for monetary damages (or otherwise) for breach of any of its representations, warranties, covenants and obligations contained in this Exhibit C or the Agreement, or any Schedule, Exhibit, certificate or affidavit, or in any other document delivered thereby, other than pursuant to the succeeding provisions of this Article 3, which shall be the sole and exclusive remedy with respect thereto. In furtherance of the foregoing provision relating to exclusive remedy, the Operating Partnership hereby expressly waives any rights or claims it may have to pursue any other remedy, whether under statute or common law against the Contributor or any of its affiliates. In no event shall the constituent members, partners, employees, officers, directors of the Contributor, be liable for monetary damages (or otherwise) for any breach of any of the representations, warranties, covenants and obligations contained in this Exhibit C of the Agreement or any Schedule, Exhibit, certificate or affidavit, or in any other document delivered thereby.

3.2 General Indemnification.

(a) The Contributor shall indemnify and hold harmless the Operating Partnership, the Company and each of their respective directors, officers, employees, agents, representatives and affiliates other than the Contributor (each of which is an “Indemnified Party”) from and against any and all Claims, losses, damages, liabilities and expenses, including, without limitation, amounts paid in settlement, reasonable attorneys’ fees, costs of investigation, costs of investigative, judicial or administrative proceedings or appeals therefrom, and costs of attachment or similar bonds (collectively, “Losses”), asserted against, imposed upon or incurred by the Indemnified Party in connection with or as a result of any breach of a representation, warranty or covenant of the Contributor contained in the Agreement (as qualified by all items set forth in the Disclosure Schedule) and including, without limitation, this Exhibit C or any Schedule, Exhibit, certificate or affidavit, or in any other document delivered thereby,).

(b) Subject to Section 2.4 of the Agreement, the Contributor shall also indemnify and hold harmless the Indemnified Parties from and against any and all Losses asserted against, imposed upon or incurred by the Indemnified Parties in connection with or as a result of all fees and expenses of the Contributor in connection with the transactions contemplated by the Agreement.

(c) With respect to any claim of an Indemnified Party pursuant to this Section 3.2, to the extent available, the Operating Partnership agrees to use diligent good faith efforts to pursue and collect any and all available proceeds under any insurance policy which covers the matter which is the subject of the indemnification prior to seeking indemnification from the Contributor until all proceeds, if any, to which the Operating Partnership or the Indemnified Party is entitled pursuant to such insurance policy have been exhausted; provided, however, that the Operating Partnership may make a claim under this Section 3.2 even if an insurance coverage dispute is pending, in which case, if the Indemnified Party later receives insurance proceeds with respect to any Losses paid by the Contributor for the benefit of any Indemnified Party, then the Indemnified Party shall reimburse the Contributor in an amount equivalent to such proceeds in excess of any deductible amount pursuant to Section 3.4(a) up to the amount actually paid by the Contributor to the Indemnified Party in connection with such indemnification (it being understood that all costs and expenses incurred by the Contributor with respect to insurance coverage disputes shall constitute Losses paid by the Contributor for purposes of this Section 3.2(c)).

3.3 Notice and Defense of Claims. As soon as reasonably practicable after receipt by the Indemnified Party of notice of any liability or claim incurred by or asserted against the Indemnified Party that is subject to indemnification under this Article 3, the Indemnified Party shall give notice thereof to the Contributor, including liabilities or claims to be applied against the indemnification deductible established pursuant to Section 3.4 hereof; provided that failure to give notice to the Contributor will not relieve it from any liability which it may have to any Indemnified Party, unless it did not learn of such claim and such failure results in the forfeiture by the Contributor of substantial rights and defenses. The

Exhibit C-7

Indemnified Party may at its option demand indemnity under this Article 3 as soon as a claim has been threatened by a third party, regardless of whether an actual Loss has been suffered, so long as the Indemnified Party shall in good faith determine that such claim is not frivolous and that the Indemnified Party may be liable for, or otherwise incur, a Loss as a result thereof and shall give notice of such determination to Contributor. The Indemnified Party shall permit the Contributor, at the Contributor’s option and expense, to assume the defense of any such claim by counsel selected by the Contributor and reasonably satisfactory to the Indemnified Party, and to settle or otherwise dispose of the same; PROVIDED, HOWEVER, that the Indemnified Party may at all times participate in such defense at its expense; and PROVIDED FURTHER, HOWEVER, that Contributor shall not, in defense of any such claim, except with the prior written consent of the Indemnified Party in its sole and absolute discretion, consent to the entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff in question to all Indemnified Parties a release of all liabilities in respect of such claims, or that does not result only in the payment of money damages which are paid in full by the Contributor. If the Contributor shall fail to undertake such defense within thirty (30) days after such notice, or within such shorter time as may be reasonable under the circumstances or as required by applicable law, then the Indemnified Party shall have the right to undertake the defense, compromise or settlement of such liability or claim on behalf of and for the account of Contributor at the Contributor’s sole cost and expense; PROVIDED, HOWEVER, that the Contributor will not be obligated to indemnify the Indemnified Parties for any compromise or settlement entered into without the Contributor’s prior written consent, which consent shall not be unreasonably withheld or delayed.

3.4 Limitations on Indemnification Under Section 3.2(a).

(a) The Contributor shall not be liable under Section 3.2(a) hereof unless and until the total amount recoverable by the Indemnified Parties from the Contributor under Section 3.2(a) exceeds One Hundred Thousand Dollars ($100,000), in the aggregate; PROVIDED, HOWEVER, that claims for Losses arising out of a breach of representations or warranties contained in Sections 2.1, 2.2, 2.4, 2.6, 2.7, and 2.9 hereof shall not be subject to such deductible amount but shall be recoverable from the first dollar of Losses.

(b) Notwithstanding anything contained herein to the contrary, the maximum liability of the Contributor in the aggregate under Section 3.2(a) hereof shall not exceed the Five Hundred Thousand Dollars ($500,000); PROVIDED, HOWEVER, that this limitation shall not apply to claims for Losses arising out of a breach of representations and warranties contained in Sections 2.1, 2.2 and 2.4. Notwithstanding anything contained herein to the contrary, the Indemnified Parties shall look, solely, first to available insurance proceeds pursuant to Section 3.2(c) above, and then solely to the Contributor’s Partnership Units (and agree to treat any return of Partnership Units as an adjustment to the consideration delivered to the Contributor pursuant to the Formation Transactions). Notwithstanding anything to the contrary in the Agreement, no Contributor shall be liable to the Indemnified Parties for any indirect, special or consequential damages, loss of profits, taxes relating to tax years beginning on or after the closing of the Formation Transactions, loss of value or other similar speculative damages asserted or claimed by the Indemnified Parties.

3.5 Limitation Period.

(a) Notwithstanding the foregoing, any claim for indemnification under Section 3.2(a) hereof must be asserted in writing by the Indemnified Party, stating the nature of the Losses and the basis for indemnification therefore on or prior to February 15, 2006, PROVIDED, HOWEVER, that claims for Losses arising out of a breach of the representations and warranties contained in Section 2.4 shall survive and may be brought indefinitely after the Closing.

Exhibit C-8

(b) Subject to Section 3.5(a), if asserted in writing on or prior to February 15, 2006, any claims for indemnification pursuant to Section 3.2(a) shall survive until resolved by mutual agreement between the Contributor and the Indemnified Party or pursuant to Section 7.14 of the Agreement, and any claim for indemnification not so asserted in writing on or prior to February 15, 2006 shall not thereafter be asserted and shall forever be waived.
