THIS CONTRIBUTION AGREEMENT (including all exhibits, hereinafter referred to as this “Agreement”) is made and entered into as of July 31, 2004 by and among Digital Realty Trust, L.P., a Maryland limited partnership (the “Operating Partnership”), San Francisco Wave eXchange, LLC, a Delaware limited liability company (“SF Wave”), Santa Clara Wave eXchange, LLC, a Delaware limited liability company (“SC Wave”), and eXchange colocation, LLC, a Delaware limited liability company (“eXchange”). SF Wave, SC Wave and eXchange are sometimes collectively referred to herein as the “Contributors” and each individually as a “Contributor”).

RECITALS

A. SF Wave currently owns a fee simple interest in the parcel of land and the buildings and other improvements affixed to or located on such land (the “Improvements”) and all rights and appurtenances related to such property located at 200 Paul Avenue, San Francisco, California (the “Paul Avenue Property”). SC Wave currently owns a fee simple interest in the parcel of land and the buildings and Improvements affixed to or located on such land and all rights and appurtenances related to such property located at 1100 Space Park Drive, Santa Clara, California (the “Space Park Property” and together with the Paul Avenue Property, the “Properties” and each a “Property”), as each Property is more fully described in Exhibit A.

B. The Operating Partnership desires to consolidate the ownership of the Properties and certain other properties owned by Global Innovation Partners, LLC (“GI Partners”) and others through a series of transactions (the “Formation Transactions”) whereby the Operating Partnership will acquire a direct fee simple interest and ownership (a “Direct Contribution”) in the Properties (the “Property Interests”) and a direct or indirect interest in such other properties.

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. As part of the Formation Transactions, the SF Wave and SC Wave will transfer their respective Property Interests to the Operating Partnership in exchange for cash and units of limited partnership interest (“Partnership Units”) in the Operating Partnership.

E. In addition, as part of the Formation Transactions, eXchange (which is an affiliate of SF Wave), desires to contribute all of its assets with respect to its colocation space licensing business at the Paul Avenue Property (the “Colocation Business”) to the Operating Partnership, and the Operating Partnership desires to acquire the assets comprising the Colocation Business, in exchange for cash and Partnership Units.

The parties acknowledge that the Operating Partnership’s acquisition of the Property Interests, the Contributed Assets (as defined in Section 1.2) and the Assumed Agreements (as defined in Section 1.2), and the assumption of the Assumed Liabilities (as defined in Section 1.4) is in connection with and subject to the consummation of the Formation Transactions and the Public Offering.

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.

Section 1.1 Contribution of Property Interests. At the Closing (as defined in Section 2.2) and subject to the terms and conditions contained in this Agreement, each Contributor shall contribute, transfer, assign, convey and deliver to the Operating Partnership, absolutely and unconditionally, and free and clear of all Liens (other than Permitted Exceptions (as defined herein)), all of its right, title and interest to the Property Interests, including all rights to indemnification in favor of such Contributor under the agreements pursuant to which such Contributor or its affiliates acquired the Property Interests transferred pursuant to this Agreement. The contribution of the Property Interests shall be evidenced by a Deed (as defined in Section 2.3(b)). The parties shall take such additional actions and execute such additional documentation as may be required by each Contributor’s operating agreement and the Amended and Restated Agreement of Limited Partnership of the Operating Partnership (the “OP Agreement”) or as reasonably requested by the Operating Partnership in order to effect the transactions contemplated hereby.

At the Closing and subject to the terms and conditions contained in this Agreement, each Contributor shall contribute, transfer, assign convey and deliver to the Operating Partnership, and the Operating Partnership shall acquire and accept, all of such Contributor’s right, title and interest in and to (i) those assets listed on Schedule 1.2, if any, and all right, title and interest held directly or indirectly by the Contributors in (x) all Fixtures and Personal Property (as defined in Section 2.21 of Exhibit C) related to each Property, and (y) all Intangible Personal Property (to the extent transferable) now or hereafter used in connection with the operation, ownership, maintenance, management or occupancy of each Property and the Colocation Business (collectively, the “Contributed Assets”), and (ii) those certain agreements listed on Schedule 1.2, and all agreements and arrangements related to each Property and to the Colocation Business to which any Contributor (or its affiliates or predecessors) is a party, directly or indirectly, including without limitation, all tenant leases, licenses or occupancy agreements related to each Property and to the Colocation Business and Service Contracts (as defined in Section 2.23 of Exhibit C) (collectively, the “Assumed Agreements”), and in each case, free and clear of any and all Liens, subject only to the Permitted Liens (as defined in Exhibit C). The contribution of the Contributed Assets and the Assumed Agreements and the assumption of all obligations thereunder shall be evidenced by a Contribution and Assumption Agreement in substantially the form of Exhibit B attached hereto. “Intangible Personal Property” shall mean all, right, title and interest relating to a Property in and to all intangible personal property now or hereafter used in connection with the operation, ownership, maintenance, management, or occupancy of such Property, including without limitation: all trade names and trade marks associated with the ownership of such Property; the plans and specifications for the Improvements; warranties; guaranties; indemnities; claims against third parties; claims against tenants for tenant improvement reimbursements; all contract rights related to the construction, operation, ownership or management of such Property; certificates of occupancy; applications, permits, approvals and licenses; insurance proceeds and condemnation awards or claims thereto to be assigned to the Operating Partnership hereunder; and all books and records relating to such Property.

2

Section 1.3 Excluded Assets. Notwithstanding the foregoing, the parties expressly acknowledge and agree that all assets and properties of the Contributors set forth on Schedule 1.3, if any, shall be deemed “Excluded Assets” and not contributed, transferred, assigned, conveyed or delivered to the Operating Partnership pursuant to this Agreement, and the Operating Partnership shall not have any rights or obligations with respect thereto.

Section 1.4 Assumed Liabilities. On the terms and subject to the conditions set forth in this Agreement, at the Closing, the Operating Partnership shall assume from the Contributors and thereafter pay, perform or discharge in accordance with their terms all of the liabilities of the Contributors listed on Schedule 1.4, if any (the “Assumed Liabilities”).

Section 1.5 Existing Loans.

(a) The Contributors have obtained certain financing encumbering each Property from (i) Greenwich Capital Financial Products, Inc., as evidenced by those certain secured promissory notes in the aggregate original principal amount of $52,000,000 (the “Greenwich Loan”), and (ii) Bank of the West, as evidenced by that certain secured promissory note in the aggregate original principal amount of $25,000,000 (the “BoW Loan” and together with the Greenwich Loan, the “Existing Loans” and each an “Existing Loan”). Such notes, deed of trusts and all other documents or instruments evidencing or securing such Existing Loans, including any financing statements, and any amendments, modifications and assignments of the foregoing, shall be referred to, collectively, as the “Existing Loan Documents.” Each Existing Loan shall be considered a “Permitted Lien” for purposes of this Agreement. The Operating Partnership at its election shall either (i) assume the applicable Existing Loan at the Closing (subject to obtaining any necessary consents from the holder of each mortgage or deed of trust related to the Existing Loans (each a “Lender” and collectively the “Lenders”) prior to Closing), (ii) take title to the Property Interest subject to the lien of the Existing Loan Documents or (iii) cause the Existing Loans to be refinanced or repaid in connection with the Closing; provided, however, that if the Operating Partnership elects to proceed under clauses (i) or (ii) of this sentence, the Operating Partnership may nonetheless, at its sole discretion, cause the Existing Loans to be refinanced or repaid after the Closing. From the date of the initial filing of the registration statement (the “Initial Filing Date”) in connection with the Public Offering, the Contributors shall use their commercially reasonable efforts to obtain within thirty (30) days from the Initial Filing Date the consent of the Lenders to the assumption of the Existing Loans by the Operating Partnership at the Closing. In addition, at or before the Closing, each Lender related to the Existing Loans shall have released the Contributors and all their respective affiliates from any liability pursuant to any recourse obligations, guarantees, indemnification agreements, letters of credit posted as security or other similar obligations or, in the absence of such release, the Operating Partnership shall have entered into an indemnification agreement with respect to the Contributors’ and their respective affiliates’ obligations under the respective Existing Loan Documents.

(b) In connection with the assumption of each Existing Loan at the Closing or refinancing or payoff of an Existing Loan after the Closing, the Operating Partnership shall be responsible for an assumption fee and prepayment premium assessed by the lender and associated with such assumption, refinancing or payoff prior to maturity or any other reasonable fee, charge, legal fees, cost or expense (collectively, “Assumption Fees”) up to a maximum of one percent (1%) of the outstanding principal balance of each Existing Loan on the date hereof (each an “Assumption Fee Cap”) and, subject

3

to Section 3.5, shall indemnify and hold harmless the Contributors from and against any liability under the Existing Loans arising from and after the Closing. Any assumption fee, prepayment premium and Assumption Fees subject to the Assumption Fee Cap for each Existing Loan shall be calculated solely with respect to such Existing Loan and shall not be aggregated or combined with any assumption fee, prepayment premium and Assumption Fees associated with any other Existing Loan. For purposes of Section 1.6 and Exhibit D, the “Excess Assumption Fee” shall be equal to the sum of (x) the amount by which Assumption Fees for the Greenwich Loan exceed one percent (1%) of the outstanding principal balance of the Greenwich Loan on the date hereof (which is $47,506,522.78), and (y) the amount by which Assumption Fees for BoW Loan exceed one percent (1%) of the outstanding principal balance of the BoW Loan on the date hereof (which is $16,052,678.03). Nothing contained in this Agreement shall preclude the Operating Partnership from reducing or increasing the indebtedness secured by the Property Interests above the amount outstanding on the Existing Loans in connection with any refinancing which may occur concurrently with or after Closing. Each Contributor shall use commercially reasonable efforts along with the Operating Partnership in seeking to process approval of the assumption of each Existing Loan or in beginning the process for any refinancing or a payoff (such as, without limitation, requesting a payoff statement from the holder(s) of each Existing Loans).

Section 1.6 Consideration and Exchange of Partnership Units. Subject to Section 1.7, the Operating Partnership shall, in exchange for the Property Interests, the Contributed Assets, the Assumed Liabilities and the Assumed Agreements, transfer to the Contributors consideration equal to the Contributors’ “Total Consideration” as indicated on Exhibit D (taking account of any adjustments to the Total Consideration pursuant to this Agreement), which shall be payable as set forth on Exhibit D. For purposes of any adjustment to Total Consideration pursuant to Sections 1.11 and 4.1(d), the Total Consideration shall be reduced by the number of Partnership Units equal to the dollar value of such adjustment divided by Twenty Dollars ($20.00). The transfer of the Partnership Units to the Contributors 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 Contributors. The parties shall take such additional actions and execute such additional documentation as may be required by such party’s operating agreement and the OP Agreement in order to effect the transactions contemplated hereby.

Section 1.7 Adjusted Consideration. Notwithstanding any other provision of this Agreement to the contrary, except to the extent otherwise expressly provided in Sections 1.11, 1.14 and 4.1(d), if the Operating Partnership in good faith determines that the ownership of any particular interests that constitute part of the Property Interests would be inappropriate for the Operating Partnership for any reason; the Operating Partnership shall elect to either (a) proceed to the Closing with no reduction in the Contributors’ Total Consideration as indicated on Exhibit D; or (b) subject to Section 1.13(d) below, terminate this Agreement in its entirety.

Section 1.8 Treatment as Contribution. The transfer, assignment and exchange 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 each Contributor hereby consents to such treatment.

4

Section 1.9 Allocation of Total Consideration. The Total Consideration shall be allocated as set forth in Schedule 1.9. The Operating Partnership and each 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 that they control to take no position inconsistent with the allocation for income tax purposes.

Section 1.10 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 Contributors shall have any further obligations hereunder except as specifically set forth herein. Notwithstanding the foregoing, the rights and obligations of the parties to that certain Mutual Nondisclosure Agreement (the “MNDA”), dated as of June 17, 2004, by and among Global Innovation Partners, LLC, a Delaware limited liability company, and Digital Realty Trust, Inc., a Maryland corporation, on one hand, and Cambay Tele.com, LLC, a California limited liability company, and Wave Exchange, LLC, a Delaware limited liability company, on the other hand, shall survive a termination of this Agreement prior to the Closing in accordance with the terms and conditions set forth in the MNDA. In addition, the Operating Partnership hereby agrees to be bound by and subject to the MNDA to the same extent as the Company, as if the Operating Partnership were an original signatory to the MNDA. Notwithstanding anything to the contrary herein or in the MNDA, the MNDA shall be terminated for all purposes upon the Closing.

Section 1.11 Risk of Loss. The risk of loss relating to the Contributors’ Property Interests and the underlying Properties prior to Closing shall be borne by the Contributors. 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 (so long as the cost of repairing such destruction or damage is in the reasonable judgment of the Operating Partnership in excess of the Maximum Per Property Total Consideration Adjustment (as defined below)), determine not to acquire the Property Interest that has been partially or totally destroyed, damaged or taken (with an adjustment to the Contributors’ Total Consideration as indicated on Exhibit D) and proceed with the acquisition of the other Property Interest. After the occurrence of any such casualty or condemnation affecting a Property, the Operating Partnership may also, at its option within thirty (30) days after the Operating Partnership is notified of any such casualty or condemnation, elect to (a) acquire such particular Property Interest and (b) direct the Contributors to pay or cause to be paid to the Operating Partnership upon or following the Closing any sums collected by the Contributors, if any, under any policies of insurance, if any, or award proceeds relating to such casualty or condemnation (to the extent that the Contributors have not applied such sums or proceeds to the restoration of the affected Property or otherwise to address the impacts of such casualty or condemnation) and otherwise assign to the Operating Partnership upon or following the Closing all rights of the Contributors to collect such sums as may then be uncollected, and/or to the extent available to the Contributors, adjust or settle any insurance claim or condemnation proceeding, which the Contributors have not adjusted or settled prior to the Closing. Under such circumstances, the Contributors’ Total Consideration shall be reduced (but, with respect to each Property considered separately, not in excess of an amount which, when aggregated with any other adjustments with respect to such Property pursuant to this Section 1.11 and/or Section 4.1(d), would exceed Five Million Dollars ($5,000,000) (the “Maximum Per Property Total Consideration Adjustment”)), by the amount of (i) any deductibles under the applicable insurance policies or award with respect to the Properties contributed at Closing and (ii) any uninsured casualty or loss with respect to the Properties contributed at Closing. Insurance on the transferred Property Interests shall be cancelled as of

5

12:01 a.m. on the Closing Date, and thereafter the Operating Partnership shall be solely responsible for all risk of loss relating to the Property Interests.

Section 1.12 Property Tax Reassessment. Notwithstanding anything to the contrary contained herein with respect to the delivery of Partnership Units to the Contributors as part of the Total Consideration, the number of Partnership Units having an aggregate value of One Million Dollars ($1,000,000) (the “Holdback Units”), based on one Partnership Unit being equal in value to the Public Offering price for one share of the Company’s common stock, shall be held by the Operating Partnership in trust for the benefit of the Contributors for a period up to the earlier of: (a) receipt of notice(s) of reassessment confirming the new assessed valuation of each Property as a result of the Closing, or (b) thirty-six (36) months following the Closing Date (the “Reassessment Period”) pursuant to this Section 1.12; provided, however, that in the event the Operating Partnership appeals or contests any such reassessment at its sole election, a portion of the Holdback Units equal to the amount being appealed or contested shall continue to be held by the Operating Partnership in trust for the benefit of the Contributors until such appeal or contest is resolved even if such resolution extends beyond the Reassessment Period. In the event of a reassessment of the property value of any Property during the Reassessment Period due to the consummation of the transactions contemplated by this Agreement, that portion of the Holdback Units with a value (based on the Public Offering price of one share of the Company’s common stock) equal to the additional annual real property taxes payable by the Operating Partnership during the sixty (60)-month period following the Closing Date as a result of such reassessment and which, under the terms of the respective Leases in place as such Leases exist as of the Closing Date, or under any Leases for the Properties entered into after the Closing Date (other than those involving a tax reimbursement obligation based upon a base year on or after the Closing Date), the Operating Partnership does not have a right to pass-through to the tenants of the applicable Property, shall be surrendered and forfeited by the Contributors. In no event shall the Contributors be responsible for any reassessment of the Property Interests solely to the extent such reassessment results from significant new construction after the Closing. Other than with respect to the Holdback Units as provided in this Section 1.12, the Contributors shall have no further obligations for any reassessment of the assessed value of the Properties or the Property Interests. After the Reassessment Period, the Operating Partnership shall deliver to the Contributors any Holdback Units not forfeited by the Contributors pursuant to this Section 1.12.

Section 1.13 Inspection and Review Period.

(a) The Operating Partnership and its employees, representatives, counsel and consultants shall have the right to review and investigate any and all conditions and aspects of the Properties, including without limitation with respect to the existence of Hazardous Materials or other environmental conditions at the Properties and all agreements and arrangements related to the operation of the Properties and the Colocation Business, from the date hereof until 5:00 p.m. (California time) on the forty-fifth (45 th) calendar day following the date hereof or such longer period required to obtain the tenant estoppels required pursuant to Section 2.3(m) (the “OP Inspection and Review Period”). Each Contributor shall provide access to the Properties and all documents, materials, books, records and files relating to the Properties and the Colocation Business in the possession of each Contributor (or its affiliates), as the Operating Partnership may reasonably request (all such items the “OP Due Diligence Documents”); provided, however, that the OP Due Diligence Documents shall not include any information of the Contributors entitled to the attorney-client privilege.

6

(b) Any on-site inspections of the Properties shall (i) be coordinated with the Contributors, (ii) occur only at reasonable times during normal business hours agreed upon by the Contributors and the Operating Partnership after at least two (2) business day’s prior written notice to the Contributors, (iii) be conducted in a manner that will not damage the Properties (except for limited invasive testing within the scope of work and in accordance with the terms and conditions described herein), unreasonably disturb or disrupt the business activities of the Contributors or interfere with the occupancy of any tenant. The Contributors shall be entitled to have a representative present during any such inspections. If the Operating Partnership desires to do any invasive testing at a Property, the Operating Partnership shall do so only after notifying the Contributors, as applicable, and obtaining the Contributors’ prior written consent thereto, which consent may be given or withheld in the sole discretion of the Contributors and may further be subject to any terms and conditions imposed by the Contributors in its sole discretion, including the prompt restoration of such Property to its condition prior to any such inspections or tests at the Operating Partnership’s sole cost and expense. Notwithstanding the foregoing, in no event shall the Operating Partnership conduct any invasive testing in any occupied tenant unit. The Operating Partnership shall keep the Property Interests free and clear of any liens arising out of the Operating Partnership’s entry onto or inspection of the Properties. At a Contributor’s sole option (but only if the Contributor shall request the same in writing), the Operating Partnership will furnish to such Contributor copies of any reports received by the Operating Partnership relating to any inspection of the Property, without representation or warranty of any kind (express, implied or otherwise) as to the content and accuracy thereof, and at no charge to the Contributor. The Company and the Operating Partnership agree to protect, indemnify, defend and hold the Contributors harmless from and against any claim for liabilities, losses, costs, expenses (including reasonable attorneys’ fees), damages or injuries arising out of, or directly resulting from the inspection of the Properties by the Operating Partnership and its employees, representatives, counsel and consultants and, notwithstanding anything to the contrary in this Agreement, such obligation to indemnify and hold harmless the Contributors shall survive any termination of this Agreement but shall expire upon the Closing.

(c) Notwithstanding anything in this Agreement to the contrary, the Operating Partnership shall have the right to terminate this Agreement for any reason or for no reason at any time prior to or after (subject to Sections 1.7 and 1.13(d)) the end of the OP Inspection and Review Period in its sole and absolute discretion, by delivering notice of termination to the Contributors. If this Agreement is terminated by the Operating Partnership prior to the expiration of the OP Inspection and Review Period pursuant to this Section 1.13(c), no party shall have any further obligations under this Agreement except to the extent set forth in any provision that specifically survives termination of this Agreement.

(d) If this Agreement is terminated by the Operating Partnership after the expiration of the OP Inspection and Review Period, and if the Operating Partnership and the Company thereafter consummate the Public Offering and the Formation Transactions prior to the Termination Date without including the Properties, other than as a result of a default or breach by any Contributor, the failure of a condition precedent to the obligations of the Operating Partnership that is not within the sole control of the Operating Partnership to cause to be satisfied, or the failure to acquire the Property Interests related to both Properties pursuant to Sections 1.11 and 4.1(d), then the Operating Partnership shall reimburse the Contributors upon the consummation of Public Offering for all reasonable and documented third-party out-of-pocket costs and expenses, including without limitation professional fees, incurred and paid by the Contributors to any third party unaffiliated consultant, professional or advisor (including without limitation legal and accounting fees) in connection with the negotiation, execution, and performance of obligations under this Agreement up to a maximum of Five Hundred Thousand Dollars ($500,000) and any costs and expenses of the Contributors incurred in excess of this amount shall not be reimbursed by the Operating Partnership or the Company and shall remain the sole obligation and responsibility of the Contributors. The Operating Partnership shall have no further monetary obligation to any Contributor for

7

failure or inability to consummate the transactions contemplated hereby other than as set forth in this Section 1.13(d).

Section 1.14 Title and Survey.

(a) Delivery of Survey. The Contributors shall cause to be prepared and delivered to the Operating Partnership within thirty (30) days after the date of this Agreement a copy of the latest ALTA-ACSM Urban survey of the Properties which shall have been prepared within two (2) years prior to the date hereof (the “Survey”). Within five (5) business days after the date of this Agreement, the Operating Partnership shall obtain a title report and commitment for title insurance (the “Title Commitment”) from a title company acceptable to the Operating Partnership in its sole discretion (the “Title Company”). The Title Commitment, the documents referred to therein and the Survey are referred to herein collectively as the “Title Documents.”

(b) Title Review and Cure. If the Title Documents show that all or part of any Property is unmarketable, or subject to a material defect, lien, encumbrance, easement, condition or restriction which is unacceptable to the Operating Partnership (each, a “Title Objection”), the Operating Partnership shall deliver written notice of such Title Objection (“Title Objection Notice”) to the Contributor by no later noon of the last day of the OP Inspection and Review Period (the “Objection Date”). If the Operating Partnership has not delivered a Title Objection Notice to the Contributors on or prior to the Objection Date, the Operating Partnership shall be deemed to have approved of title to the Properties. The Contributors shall have no obligation to cure title objections, except for liens and security interests created or assumed by, under or through the Contributors, which liens and security interests the Contributors shall cause to be released at the Closing. If the Contributors are unable or unwilling to cure a Title Objection which it is not otherwise obligated to cure (other than with respect to taxes and assessments to be paid current through the Closing Date), the Contributors shall give the Operating Partnership written notice of that fact within five (5) business days of the Title Objection Notice. Within ten (10) business days after receipt of the Contributor’s response to the Title Objection Notice, the Operating Partnership shall elect to either: (i) waive such Title Objection and accept such title to the Property subject to such Title Objection; or (ii) terminate this Agreement with respect to such Property (with an adjustment to the Contributors’ Total Consideration as indicated on Exhibit D) or, at the Operating Partnership’s election, in its entirety, by giving written notice of termination to the Contributor. After termination of this Agreement in its entirety in accordance with this Section 1.14(b), neither the Operating Partnership nor the Contributors shall have any further obligations hereunder or liability to the other, except for those obligations which survive the termination of this Agreement. All matters contained in the Title Report or disclosed in the Survey which are not objected to by the Operating Partnership by the Objection Date shall be deemed to have been approved by the Operating Partnership (except for those items which the Contributors are otherwise obligated to cure and current taxes and assessments to be paid current through the Closing Date). Any liens, encumbrances, easements, restrictions, conditions, covenants, rights, rights of way and other matters affecting title to the Property which were not disclosed by the Title Documents (collectively, “Intervening Liens”) shall be subject to the Operating Partnership’s approval. The Operating Partnership shall have five (5) business days after notice of any Intervening Lien, together with a true, complete and legible copies of all documents referred to in such notice, to deliver written objections thereto to the Contributors. Any Intervening Liens which are not timely objected to by the Operating Partnership shall be deemed to have been approved by the Operating Partnership. All matters approved or deemed to have been approved by the Operating Partnership and all Title Objections subsequently waived by the Operating Partnership shall hereinafter be deemed to be “Permitted Exceptions.” In the event that the Operating Partnership objects to any Intervening Lien and the Contributors fail to remove such Intervening Lien, the Operating Partnership

8

shall have the right to terminate this Agreement with respect to such Property or, at the Operating Partnership’s election, in its entirety.

Notwithstanding the foregoing, neither the Operating Partnership nor the Contributors may settle or otherwise resolve any such claim, suit or proceeding which could have an adverse tax effect on the other party or its affiliates without the consent of the other party, such consent not to be unreasonably withheld. The Contributors and the Operating Partnership shall retain all tax returns, schedules and work papers, and all material records and other documents relating thereto, until the expiration of the statute of limitations (and, to the extent notified by any party, any extensions thereof) of the taxable years to which such tax returns and other documents relate and until the final determination of any tax in respect of such years.

Section 4.5 Tax Protection Covenants. The Operating Partnership hereby agrees as follows:

(a) Section 704(c) Allocations and Methods. The Operating Partnership shall elect to use the “traditional method” (without any curative or remedial actions) as set forth in Section 1.704-3(b) of the Treasury Regulations for making allocations under Section 704(c) of the Code with respect to the Property Interests.

(b) Limitation on Sale of Property Interests.

(i) During the Tax Protection Period (as defined below), the Operating Partnership shall not, and shall not permit any other entity which holds any of the Property Interests to, engage in any direct or indirect sale, conveyance, transfer or other disposition, voluntarily or involuntarily, of all or any portion of the Property Interests or any interest therein in a transaction that would result in the recognition of “built-in gain,” within the meaning of Section 1.704-3(a)(3)(ii) of the Treasury Regulations, with respect to such Property Interests (“Built-In Gain”) by the Contributors, including distributees and transferees of the Contributors who received Partnership Units in a carry-over basis transaction, but excluding charities and other tax-exempt entities, or trusts to the extent such organizations are beneficiaries (such recipients, distributees and transferees being referred to in this Agreement as “Tax-Protected Partnership Unit Holders”). For the avoidance of doubt, the Operating Partnership and each Contributor agree that during the Tax Protection Period, the Operating Partnership will be permitted to complete a transaction described in Section 721, 1031 or 1033 of the Code, or other applicable non-recognition Code provision, with respect to Property Interests, provided that no Built-In Gain is recognized by the Tax-Protected Partnership Unit Holders during the Tax Protection Period. Any replacement property or interests acquired in such transactions shall be referred to as the “Replacement Property” and shall be entitled to the same tax protections under this Section 4.5 as the Property Interests.

20

(ii) As used in this Agreement, the “Tax Protection Period” for any Property Interests shall mean the period beginning on the Closing Date and ending on the earlier of (a) ninth (9 th) anniversary of the Closing Date or (b) the date (the “Stop Date”) on which less than twenty-five percent (25%) of the Partnership Units issued to the Contributors are held by Tax Protected Partnership Unit Holders.

(c) Nonrecourse Indebtedness. During the Tax Protection Period and absent a change in law, the Operating Partnership will allocate “excess nonrecourse liabilities” (within the meaning of Section 1.752-3(a)(3) of the Treasury Regulations) secured by the Property Interests, if any, to each of the Tax-Protected Partnership Unit Holders first to the extent of such Tax-Protected Partnership Unit Holder’s Built-In Gain in the Property Interests, but only to the extent such Built-In Gain exceeds such Tax-Protected Partnership Unit Holder’s Code Section 704(c) “minimum gain” in such Property Interests, described in Section 1.752-3(a)(2) of the Treasury Regulations.

(d) Guarantee Opportunity.

(i) The Operating Partnership agrees that, during the period beginning on the Closing Date and ending on the earlier of the ninth (9 th) anniversary of the Closing Date or the Stop Date, the Operating Partnership shall permit each Tax-Protected Partnership Unit Holder, upon request, the opportunity to provide one or more “bottom dollar” guarantees (each, a “Guarantee”) of a portion or portions of the indebtedness of the Operating Partnership or its affiliates equal to a dollar amount specified in writing by such Tax-Protected Partnership Unit Holder to the Operating Partnership (but in no case more than Twenty Million Dollars ($20,000,000) in the aggregate for all Tax-Protected Partnership Unit Holders). If any Guarantee of debt of an affiliate of the Operating Partnership (other than an affiliate disregarded from the Operating Partnership for federal income tax purposes) fails to cause the allocation of the guaranteed portion of such debt to Tax-Protected Partnership Unit Holders under Section 752 of the Code, such failure shall be treated as a breach of this Section 4.5(d), and require the Operating Partnership to make a payment to the applicable Tax-Protected Partnership Unit Holders in accordance with Section 4.5(e). The Guarantee provided by a Tax-Protected Partnership Unit Holder (i) shall not have relatively higher economic risk than other guarantees, if any, provided by other Partnership Unit holders of indebtedness secured by the same property(s) as the indebtedness covered by such Tax-Protected Partnership Unit Holder’s Guarantee; and (ii) shall have relatively higher economic risk than guarantees, if any, provided by the Operating Partnership or its affiliates, of the same portion of indebtedness covered by such Tax Protected Partnership Unit Holder’s Guarantee. The Operating Partnership agrees to make available to Tax-Protected Partnership Unit Holders the opportunity to provide Guarantees as provided in this Section 4.5(d) with respect to indebtedness (and collateral therefor, if any) which, as of the date the respective Guarantee is delivered or any subsequent guarantee of such debt is delivered, has characteristics of the type described in Section 4.5(d)(ii), or such other characteristics as may be hereafter mutually agreed upon by the Operating Partnership and one or more Tax-Protected Partnership Unit Holders (but only with respect to such holders’ guarantees) from time to time. Each Guarantee shall be on a form provided by the guarantor, subject to the Operating Partnership’s consent, which shall not be unreasonably withheld.

(ii) As described in Section 4.5(d)(i), the Tax-Protected Partnership Unit Holders will be entitled to guarantee indebtedness of the Operating Partnership which meets the following risk profile standards: (i) it is able to be guaranteed, either directly or indirectly through rights of subrogation, indemnity, contribution, reimbursement or similar rights in favor of the obligor or one or more other guarantors of the guaranteed indebtedness; (ii) it is secured by specific property(s) of the Operating Partnership or an entity disregarded from the Operating Partnership described in Section 4.5(h); and (iii) the aggregate amount of all guarantees of such indebtedness, plus the amount of any senior indebtedness secured by such property(s) (i.e., if the indebtedness being Guaranteed is secured by a junior

21

lien on the security property and whether or not such senior indebtedness is being Guaranteed), does not exceed sixty-five percent (65%) of the fair market value (as determined by the Operating Partnership in its reasonable judgment) of such property(s). For example, if a property has a value of $100, is subject to a first mortgage loan of $55, and a second mortgage loan of $30, the guarantors would be willing to Guarantee up to $10 of the second mortgage loan (whether or not they Guaranteed the first mortgage loan).

(iii) Each Contributor acknowledges on its own behalf and on behalf of the Tax-Protected Partnership Unit Holders that (A) the ability to execute Guarantees shall only be available to the Tax-Protected OP Unit Holders and, by providing such ability to execute Guarantees, the Operating Partnership makes no representations, warranties or covenants regarding its current or expected financial condition, the current or expected financial position of any property securing the guaranteed loan or the terms of any such loan, nor shall the Operating Partnership have any obligation to keep any guarantor informed of any changes in any of the foregoing, or of any changes in the characteristics of any guaranteed loan (or any collateral therefor, if any) occurring after the date the Guarantee is delivered (including any changes in or deviations from the characteristics of such loan (or the collateral therefor, if any) that are described in Section 4.5(d)(ii) and each such guarantor fully assumes the risk of providing such Guarantee and keeping itself informed of any such changes, or other developments and occurrences which might impact the risk to such guarantor of providing or maintaining any such Guarantee, (B) the ability to execute Guarantees shall cease in accordance with the terms of this Agreement, (C) each Guarantor shall have reviewed with its financial and legal advisors the potential consequences and liabilities that may be associated with any guarantee provided pursuant to this Agreement, (D) neither the Operating Partnership nor its advisors have prepared or undertaken a legal review (and make no representations or warranties) as to the effectiveness of any Guarantee for federal income tax purposes, or any legal implications (e.g., order of payment, priority) that such Guarantee or any obligations of the guarantor and rights of the creditor thereunder may involve under federal or state law, and (E) the Operating Partnership may, at any time, refinance or repay any indebtedness guaranteed by a Guarantee by providing notice of such event to the Contributor at least thirty (30) days prior to such refinancing or repayment, and in such case, the Operating Partnership shall, upon request, permit each Tax-Protected Partnership Unit Holder the opportunity to execute a Guarantee with respect to substitute indebtedness on the terms otherwise provided in this Section 4.5. The foregoing provisions of this Section 4.5(d)(iii) shall in no way limit the obligations of the Operating Partnership under Section 4.5(d)(i). Notwithstanding any provision in this Agreement to the contrary, provided the Operating Partnership meets its obligations under this Section 4.5(d), no tax payment alternative provided in Section 4.5(e) shall be available to the Tax-Protected Partnership Unit Holders if it is later determined (at any time) that a Guarantee provided pursuant to this Agreement was ineffective in allocating liabilities to a guarantor for federal income tax purposes and, as a result, the corresponding guarantor recognizes taxable income.

(e) Tax Payment Alternative. In lieu of complying with any of the provisions set forth in Sections 4.5(a) through (d) above, the Operating Partnership shall have the right, in conjunction with any disposition of the Property Interests, incurrence or repayment of indebtedness, or other event to which the provisions of Sections 4.5(a) through (d) would otherwise apply, to pay to all of the Tax-Protected Partnership Unit Holders then holding Partnership Units at the time of such disposition, incurrence, repayment or transaction, promptly upon demand at any time following the occurrence of the same, cash in an amount equal to the sum of (i) the full amount of state and federal income taxes that would be payable by the Tax-Protected Partnership Unit Holders as a result of such disposition, incurrence, repayment or transaction and (ii) the amount of such taxes that would be payable by the Tax-Protected Partnership Unit Holders on any payments made as a result of subparagraphs (i) and (ii) of this Section 4.5(e), assuming for such purpose that the Tax-Protected Partnership Unit Holders are required to pay state and federal income taxes at the highest applicable state and federal income tax rates applicable to such transaction, but taking into account the deductibility of state taxes. In the event of any breach by

22

the Operating Partnership, or its affiliates or successors, of the tax protections set forth in this Section 4.5, each Tax-Protected Partnership Unit Holder, as its sole remedy, shall be entitled to a payment of damages by the Operating Partnership, with the amount of such damages determined consistently with the principles set forth in this Section 4.5(e).

(f) Reporting. Each of the Contributors and the Operating Partnership (i) agree that the contribution transaction pursuant to this Agreement shall constitute a “Capital Contribution” to the Operating Partnership and is intended to be governed by Section 721(a) of the Code (subject to the limitations and qualifications of Subchapter K of the Code), (ii) intend that no gain or loss shall be recognized by any Contributor for income tax purposes as a result of such transaction, provided Contributor provides information to the Operating Partnership reasonably demonstrating that the “disguised sale” rules in Section 707 of the Code are not applicable, (iii) intend that any debt described in Section 4.5(c) (up to the amount of the Built-In Gain) and Section 4.5(d) (to the extent of the Guarantees) shall be allocated to Tax-Protected Partnership Unit Holders, (iv) shall report such transaction in a manner consistent with such intent, except to the extent that a final determination within the meaning of Section 1313(a) of the Code requires otherwise, and (v) agree that it will not take any action that could jeopardize such tax treatment.

(g) Information Regarding Income Allocations. The Operating Partnership will cooperate and act in good faith to provide each Contributor through the Closing all information reasonably requested by such Contributor in evaluating the federal income tax consequences of the transaction including the impact of projected income allocations, taking Section 704(c) of the Code into account. The Operating Partnership will also cooperate with the Tax-Protected Partnership Unit Holders subsequent to the Closing, including by providing, following written request, information reasonably necessary to facilitate such holders’ tax planning.

(h) Performance Through Disregarded Entities. The Operating Partnership may exercise its rights, and perform its obligations, under this Section 4.5, through one or more entities which are disregarded from Operating Partnership for federal income tax purposes, provided the use of any such entity does not adversely affect any Tax-Protected Partnership Unit Holder (including from an economic or federal income tax perspective).

(i) Capital Account Deficits. Absent a change in law, for purposes of Section 13.3 of the OP Agreement, a guarantee of the Operating Partnership’s indebtedness shall be treated as a Capital Account (as defined in the OP Agreement) deficit make-up obligation for purposes of Sections 704(b) and 704(c) of the Code and regulations promulgated thereunder, and shall be taken into account for purposes of determining any Adjusted Capital Account Deficit (as defined in the OP Agreement) of the guarantor.

(j) Survival. The provisions of this Section 4.5 shall survive the Closing.

ARTICLE 5.

POWER OF ATTORNEY

Section 5.1 Grant of Power of Attorney. Each 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 such Contributor, to act in the name, place and stead of such 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 Property Interests, the Contributed Assets, the Assumed Agreements or the Assumed Liabilities 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 such 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 G, which may be recorded by the Operating Partnership only in the official records of San Francisco County (with respect to SF Wave and eXchange) or Santa Clara County (with respect to SC Wave), and only if and when necessary for the Operating Partnership to record a document in such county in accordance with this Agreement.

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. Each Contributor agrees that, at the request of Operating Partnership it will promptly execute and deliver to the Operating Partnership a separate power of attorney on the same terms set forth in this Article 6, such execution to be witnessed and notarized, and in recordable form (if necessary). Each Contributor hereby authorizes the reliance of third parties on each of the Power of Attorney.

Each 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 5.2 Limitation on Liability. It is understood that the Attorney-in-Fact assumes no responsibility or liability to any person by virtue of the Power of Attorney granted by each Contributor hereby. The Attorney-in-Fact makes no representations with respect to and shall have no responsibility for the Formation Transactions or the Public Offering, or the acquisition of the Property Interests, the Contributed Assets or the Assumed Agreements by the Operating Partnership or the assumption of the Assumed Liabilities by the Operating Partnership and shall not be liable 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. Each 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 each 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. Each 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

24

counsel. It is understood that the Attorney-in-Fact may, without breaching any express or implied obligation to each Contributor hereunder, release, amend or modify any other power of attorney granted by any other person under any related agreement.

Section 5.3 Ratification; Third Party Reliance. Each 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 such Contributor under this Article 6, and each 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 6.

Section 6.11 Survival. It is the express intention and agreement of the parties hereto that, subject to Section 3.7 of Exhibit C attached hereto, 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.

Except as set forth in the Disclosure Schedule, each Contributor jointly and severally 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. Each Contributor is duly formed, validly existing and in good standing under the laws of the jurisdiction of its formation. Each Contributor has all requisite power and authority to enter into this 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 each Contributor has been duly and validly authorized by all necessary action of each Contributor. The Agreement and each agreement, document and instrument executed and delivered by or on behalf of

Exhibit C-3

each Contributor pursuant to the Agreement constitutes, or when executed and delivered will constitute, the legal, valid and binding obligation of each Contributor, each enforceable against each 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 any Contributor in connection with the execution, delivery and performance of the Agreement 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 Properties, taken as a whole (a “Material Adverse Effect”).

2.4 Ownership of the Property Interest; Contributed Assets.

(a) Except as set forth in Schedule 2.4 to the Disclosure Schedule, each Contributor is the sole owner of its respective Property 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 such Property Interest, free and clear of any Liens (other than the Permitted Liens), and, upon delivery of consideration for such Property Interests as herein provided, 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).

(b) Except as set forth in Schedule 2.4 to the Disclosure Schedule, the Contributors are the sole owner of the Contributed Assets, beneficially and of record, free and clear of any Liens of any nature (other than Permitted Liens) and has full power and authority to convey the Contributed Assets, free and clear of any Liens (other than the Permitted Liens), and, upon delivery of consideration for such Contributed Assets as provided herein, the Operating Partnership will acquire good and marketable title thereto, free and clear of any Liens (other than Permitted Liens and any liens arising through the Operating Partnership). The Property Interests, Contributed Assets and Assumed Agreements (including without limitation all assets and agreements listed in Schedule 1.2) constitute all assets, rights, interests, and property interests owned or held by the Contributors related to the Properties and the Colocation Business.

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 any Contributor, (B) any agreement, document or instrument to which any Contributor is a party or by which the Contributor, Property Interests, or the Contributed Assets 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 any Contributor or by which any Contributor, or any of their assets or properties (including the Contributed Assets) 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.

Exhibit C-4

2.6 Non-Foreign Status. Each 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. Each Contributor will provide affidavits at the Closing to this effect as provided for in Section 2.3(h) of the Agreement.

2.7 Withholding. Each 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 any Contributor fails to provide such certificates or affidavits, the Operating Partnership may withhold a portion of any payments otherwise to be made to such Contributor as required by the Code or applicable state law.

2.8 Investment Purposes. Each 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 exemption is predicated in part on the accuracy and completeness of the representations and warranties of each Contributor contained herein. In furtherance thereof, each Contributor represents and warrants to the Company as follows:

2.8.1 Investment. Each 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, except that the Contributors may convey the Partnership Units to the limited liability companies identified in Schedule 2.8 so long as, (i) any conveyance will be made on a pro rata basis in accordance with the terms of the operating agreement of such Contributor, (ii) each such limited liability company is an “accredited investor” (as defined in Rule 501(a) of Regulation D promulgated pursuant to the Securities Act of 1933, as amended) and has executed and delivered to the Operating Partnership on or prior to the date hereof a completed and accurate Accredited Investor Questionnaire (in the form delivered to the Contributors), (iii) each such limited liability company has executed and delivered to the Operating Partnership its respective “Partnership Unit Placement Agreement” (in the form delivered to the Contributors) on or prior to the date hereof, and (iv) the “Investor Representation Letter” (in the form delivered to the Contributors) has been executed and delivered to the Operating Partnership by the parties named therein. Each limited liability company for which the requirements set forth in the preceding sentence have been satisfied shall be referred to as a “Permitted Transferee.” Each 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, except to Permitted Transferees pursuant to the terms of the respective Partnership Unit Placement Agreement or, after the holding period set forth in Section 2.8.3, by such Permitted Transferees to their respective direct members (each of which is an accredited investor), 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 each 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, and (iii) the Transfer is permitted pursuant to the OP Agreement. 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.

Exhibit C-5

2.8.2 Knowledge. Each 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. Each 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; each 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 Partnership Units as each Contributor deems necessary or desirable, has had cash flow and operations data for the Properties 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 Properties, the business and prospects of the Company and the Operating Partnership and the Partnership Units which each 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. Each Contributor acknowledges that it has been advised that (i) the Partnership Units, except as set forth in Section 2.8.1, must be held for twelve (12) months and may have to be held indefinitely thereafter, and each 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. Each Contributor is an “accredited investor” (as such term is defined in Rule 501(a) of Regulation D under the Act). Each Contributor has previously provided the Operating Partnership with a duly executed Accredited Investor Questionnaire. No event or 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

Exhibit C-6

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 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. Except as set forth in Schedule 2.9 to the Disclosure Schedule, no Contributor nor any of such 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, each Contributor will be solvent immediately following the transfer of the Property Interest and the Contributed Assets to the Operating Partnership.

Exhibit C-7

No tax lien or other charge exists or will exist upon consummation of the transactions contemplated hereby with respect to any Property, except such tax liens for which the tax is not delinquent and has been properly reserved for payment by each Contributor. The copies of the real property tax bills for each Property for the current tax year which have been furnished or made available to the Operating Partnership are true and correct copies of all of the tax bills for such tax year actually received by any Contributor or any Contributor’s agents for the Property. For federal income tax purposes, each Contributor is, and at all times during its existence has been either (i) a partnership or limited liability company taxable as a partnership (rather than an association or a publicly traded partnership taxable as a corporation) or (ii) a disregarded entity. Each Contributor has timely and properly filed all Tax Returns relating to Other Taxes required to be filed by it and has timely paid all Other Taxes required to be paid by it. No Contributor has requested any extension of time or agreed to any extension of the applicable statue of limitations within which to file any pending Tax Return relating to Other Taxes.

No Contributor is 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 Property Interests or the Contributed Assets, 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.

2.13 Compliance With Laws. In connection with the operation of the Properties or the Colocation Business, except as set forth in Schedule 2.13 to the Disclosure Schedule, to the Contributors’ Knowledge, the Properties and the Colocation Business have been maintained or operated and on the date hereof are, and as of the Closing Date will be, in compliance in all material respects with all applicable laws, ordinances, rules, regulations, codes, orders and statutes (including, without limitation, those currently relating to fire safety, conservation, parking, Americans with Disabilities Act, zoning and building laws) whether federal, state or local, foreign. Compliance with Environmental Laws is not addressed by this Section 2.13, but rather solely by Section 2.17.

2.14 Eminent Domain. Except as set forth in Schedule 2.14 to the Disclosure Schedule, there is no existing or, to the Contributors’ Knowledge, proposed or threatened condemnation, eminent domain or similar proceeding, or private purchase in lieu of such a proceeding, in respect of all or any material portion of the Properties.

Exhibit C-8

2.16 Real Property.

(a) None of the Contributors, nor, except as set forth in Schedule 2.16(a) to the Disclosure Schedule, any other party to any material agreement affecting the Properties, has given to the Contributor or, to the Contributors’ Knowledge, received any notice of any uncured default with respect to any material agreement affecting the Properties which would have a material adverse effect on one or more Properties, and, no event has occurred or, to the Contributors’ Knowledge, is threatened, which through the passage of time or the giving of notice, or both, would constitute a default thereunder which would have a material adverse effect on one or more Properties or would cause the acceleration of any material obligation of any party thereto or the creation of a Lien upon any Property, except for Permitted Liens. To the Contributors’ Knowledge, such agreements are valid and binding and in full force and effect, have not been amended, modified or supplemented since such time as such agreements were made available to the Operating Partnership, except for such amendments, modifications and supplements delivered or made available to the Operating Partnership.

(b) To the Contributors’ Knowledge, except as set forth in Schedule 2.16(b) to the Disclosure Schedule, each Contributor owns fee title to the applicable Property as described in the Preliminary Title Reports and has insurable fee simple title to such Property.

No Contributor has received any notice from the United States Environmental Protection Agency or any other federal, state, county or municipal entity or agency that regulates Hazardous Materials or public health risks or other environmental matters or any other private party or Person claiming any violation of, or requiring compliance with, any Environmental Laws or Environmental Permits or demanding payment or contribution for any Release or other environmental damage in, on, under, or upon any of the Properties. No investigation or litigation with respect to Hazardous Materials located in, on, under or upon any of the Properties is pending or, to the Contributors’ Knowledge, has been threatened in the last twelve months by any Governmental Entity or any third party. To the Contributors’ Knowledge, except as may be disclosed in Schedule 2.17 to the Disclosure Schedule or the Environmental Reports, no environmental conditions exist at, on, under, upon or affecting the Properties or any portion thereof that would reasonably be likely to result in any material claim, liability or obligation under any Environmental Laws or Environmental Permit or any material claim by any third party.

2.18 Trademarks and Tradenames; Proprietary Rights.

(a) There are no actions or other judicial or administrative proceedings against the Contributor, or the Properties pending or, to the Contributors’ Knowledge, threatened in the last twelve months, that concern any copyrights, copyright application, trademarks, trademark registrations, trade names, service marks, service mark registrations, trade names and trade name registrations or any trade secrets being transferred to the Operating Partnership hereunder (the “Proprietary Rights”) and that, if adversely determined, would have a Material Adverse Effect. There are no patents or patent applications relating to the operations of the Properties as conducted prior to the Closing.

(b) To the Contributors’ Knowledge, the current use of the Proprietary Rights does not conflict with, infringe upon or violate any copyright, trade secret, trademark or registration of any other person.

To the Contributors’ Knowledge, except as set forth in the Preliminary Title Reports or the Property Reports, as of the date hereof, or may be disclosed in the Title Policies as of the Closing, there have been no alterations to the exteriors of any of the buildings or other improvements on any Property that would render any surveys or plans provided to the Operating Partnership in connection with the Formation Transactions materially inaccurate or otherwise reflect a material deficiency in title to such improvements.

2.20 Leases. As used herein, the term “Leases” shall include all leases, licenses, tenancies, possession agreements and occupancy agreements related to the Properties and the Colocation Business, and all references to “tenants” hereunder shall include all tenants, licensees or parties in possession under any such documents. Schedule 1.2 contains a complete and accurate list of all Leases.

The Operating Partnership is authorized and empowered to amend, modify or waive any provisions of the Pledge Agreement on behalf of the Indemnified Parties. The Operating Partnership agrees to act as such on the express conditions contained in this Section 3.4. The provisions of this Section 3.4 are solely for the benefit of the Operating Partnership and the Indemnified Parties and no Contributor shall have any rights as a third party beneficiary of any of the provisions hereof.

(b) The Operating Partnership shall have no duties, obligations or responsibilities to the Indemnified Parties except those expressly set forth in this Section 3.4 or in the Pledge Agreement.

Exhibit C-13

Neither the Operating Partnership nor any of its officers, directors, employees or agents shall be liable to any Indemnified Party for any action taken or omitted by them under this Section 3.4 or under the Pledge Agreement, or in connection with this Section 3.4 or the Pledge Agreement, except that the Operating Partnership shall be obligated on the terms set forth in this Section 3.4 for performance of its express obligations under the Pledge Agreement. In performing its functions and duties under the Pledge Agreement, the Operating Partnership shall exercise the same care which it would exercise in dealing with a security interest in collateral held for its own account, but the Operating Partnership shall not be responsible to any Indemnified Party for any recitals, statements, representations or warranties in the Pledge Agreement or for the execution, effectiveness, genuineness, validity, enforceability or sufficiency of the Pledge Agreement or the Collateral or the transactions contemplated thereby.

The Operating Partnership shall be entitled to rely upon the advice of legal counsel, independent accountants, and other experts selected by the Operating Partnership in its sole discretion.

(d) Each Indemnified Party shall, jointly and severally, reimburse and indemnify the Operating Partnership and its directors, officers, employees and agents for any damage, expense, loss, cost, claim or liability which may be imposed on, incurred by, or asserted against the Operating Partnership or such other persons in any way relating to or arising out of this Section 3.4 or the Pledge Agreement or any action taken or omitted by the Operating Partnership or such other persons under this Section 3.4 or the Pledge Agreement. The obligations of the Indemnified Parties under this Section 3.4(d) shall survive the termination of this Agreement and the Pledge Agreement.

3.5 Notice and Defense of Claims. Subject to Section 4.4 of the Agreement, 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 Contributors, including liabilities or claims to be applied against the indemnification deductible established pursuant to Section 3.6 hereof; provided that failure to give notice to the Contributors 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 Contributors of substantial rights and defenses. The 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 the Contributors. The Indemnified Party shall permit the Contributors, at the Contributors’ option and expense, to assume the defense of any such claim by counsel selected by the Contributors 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 Contributors 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 Contributors. If the

Exhibit C-14

Contributors 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 Contributors at the Contributors’ sole cost and expense; PROVIDED, HOWEVER, that the Contributors will not be obligated to indemnify the Indemnified Parties for any compromise or settlement entered into without the Contributors’ prior written consent, which consent shall not be unreasonably withheld or delayed.

3.6 Limitations on Indemnification Under Section 3.2(a).

(a) The Contributors shall not be liable under Section 3.2 (a) hereof unless and until the total amount recoverable by the Indemnified Parties from the Contributors under Section 3.2(a) exceeds One Hundred Fifty Thousand Dollars ($150,000), 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, 2.6, 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 Contributors in the aggregate under Section 3.2(a) hereof shall not exceed Five Million Dollars ($5,000,000), PROVIDED, HOWEVER, that this limitation shall not apply to claims for Losses arising out of a breach of the covenant contained in Section 4.1(d). Notwithstanding anything contained herein to the contrary, the Indemnified Parties shall look, first to available insurance proceeds pursuant to Section 3.2(c) above, and then to the Contributors’ Partnership Units pledged pursuant to the Pledge Agreement, for indemnification under this Article 3, valuing such Partnership Units based upon the initial public offering price of the Common Stock (and agree to treat any return of Partnership Units as an adjustment to the consideration delivered to the Contributors pursuant to the Formation Transactions). Other than with respect to a claim for indemnification with respect to the Holdback Units pursuant to Section 1.12 of the Agreement, following the Closing and the issuance of Partnership Units to a Contributor, no Indemnified Party shall have recourse to any other assets of such Contributor other than the Partnership Units pledged by such Contributor pursuant to the Pledge Agreement. Notwithstanding anything to the contrary in this 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.

3.7 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 the representation and warranty contained in Section 2.4 and 2.16(b) shall not survive Closing, and no claims for Losses arising out of a breach of the representation and warranty contained in Section 2.4 or 2.16(b) may be brought after the Closing.

(b) Subject to Section 3.7(a), if asserted in writing on or prior to February 15, 2006, any claims (other than claims under Section 2.4 and 2.16(b)) for indemnification pursuant to Section 3.2(a) shall survive until resolved by mutual agreement between each Contributor and the Indemnified Party or determination pursuant to Section 6.14 of the Agreement, and any claim for indemnification pursuant to Section 3.2(a) not so asserted in writing on or prior to February 15, 2006 shall not thereafter be asserted and shall forever be waived.

Property Manager shall have the right from time to time to submit proposed revised budgets to Owner, and Owner shall determine whether or not such revised budgets should be approved. Property Manager shall use diligence and all reasonable efforts to prevent the actual costs of maintaining and operating the Property from exceeding the Approved Operating and Capital Budgets.

All budgets shall be effective only when approved by Owner. Owner may revoke its approval of any budget at any time provided that Owner supplies Property Manager with an Owner-approved budget to replace such revoked budget. Owner may amend its approval of any budget and require the budget to be amended to conform to such approval at any time and, in such event, only the budget as so amended shall be deemed approved. Property Manager shall take such action as is necessary to implement any newly approved or amended budget as quickly as reasonably possible, but in any event within thirty (30) days after receipt of any such newly approved or amended budget. After revoking or amending an Approved Budget, Owner shall have the right to require Property Manager to terminate any agreements or void any actions which are no longer consistent with an Approved Budget, provided that Owner bears the expense and liability (if any) of terminating any agreements which are not terminable on thirty (30) days notice (or less).

All monies so collected shall be deposited immediately in the Property Lockbox Account.

2.2.5 Collections. Property Manager shall undertake the periodic billing of rents and monetary payments due from tenants of the Property, and thereafter shall use reasonable efforts to pursue collection of all such rents and other payments. Property Manager shall not terminate any lease, lock out any tenant, institute any suit for rent or for use and occupancy, provide notice by legal service to pay rent or quit or institute proceedings for recovery of possession without the prior approval of Owner. Only legal counsel designated or approved by Owner shall be retained in connection with any such suit or proceeding, and Property Manager upon request shall recommend legal counsel and furnish Owner with the estimated costs of legal services to be incurred in bringing such suit or proceeding. In the event any tenant of the Property is delinquent in any payment due to Owner or is otherwise in material default under the terms of its lease for a period of more than thirty (30) days, Property Manager shall immediately notify Owner and Owner shall have the right, but not the obligation, to contact the tenant directly with respect to the delinquency or default.

Notwithstanding the foregoing, any and all expenditures (regardless of cost and type) that constitute capital expenditures must be authorized in advance by Owner or Manager in accordance with Section 2.2.8 below. Property Manager also shall institute and effectuate a preventative maintenance program. “Institutional Owner Practices” shall mean the practices of a majority of the owners of the most highly valued institutionally owned first class investment grade office projects in the area in which the Property is located.

-6-

(b) Notwithstanding anything to the contrary in this Agreement, in the event of an emergency in which there is an immediate danger to persons or property or in which action is required in order to avoid suspension of services, Property Manager shall take such action as it believes in good faith to be reasonable and prudent under the circumstances. Property Manager shall be reimbursed promptly for any expenses so incurred in such action, even if not contained or contemplated in an Approved Operating Budget or an Approved Capital Budget so long as Property Manager makes a reasonable effort to consult with Owner in advance and, in any event, notifies Owner as soon as reasonably possible but in no event later than twenty-four (24) hours of taking such action explaining the reasons therefor.

2.2.7 Contracts. Property Manager shall not execute any contract or other agreement affecting the Property without Owner’s or Manager’s prior written consent; provided, however, that Owner’s consent shall not be required with respect to any utility or service contract which (a) is entered into in the usual course of business, (b) has a term of one year or less and (c) is specifically provided for in the Approved Operating Budget.

2.2.8 Operating and Capital Expenses.

(a) Property Manager shall use reasonable efforts to pay, in a commercially reasonable manner, all normal operating expenses of the Property as specifically provided in the Approved Operating Budget (and not paid directly by tenants) with funds from the Property Disbursement Account (as defined in Section 7.2).

(b) All capital expenditures without exception must be authorized in writing by Owner in advance. Property Manager shall not enter into any contract for any nonrecurring item of maintenance or repair, or incur any liability, or make any expenditure for any single operating expense item (excluding utility expenses) in excess of the Approved Operating Budget, unless the same shall have been earlier approved by the Owner by virtue of its specific inclusion in the Budget or otherwise in writing or unless Property Manager used its reasonable efforts to contact Owner to no avail and, in Manager’s opinion, using sound business judgement, the expenditure was immediately required due to an emergency situation for the preservation and safety of the Property, to avoid the suspension of any essential service to or for the Property, or to avoid danger to life or property at the Property. In such an emergency situation, Property Manager shall continuously endeavor by its reasonable efforts to inform Owner or Manager of the condition and necessity of such expenditure. Unless provided for in an

-7-

Approved Operating Budget or otherwise authorized by Owner, Property Manager is required to obtain specific approval on a case-by-case basis for expenditures as follows:

Property Manager shall keep Owner informed, or cause Owner to be informed, of any change in the amount of, or the method of calculating, real or personal property assessments or Taxes relating to the Property, and shall recommend, from time to time, the advisability of engaging an independent tax consultant for purposes of contesting either the validity or the amount thereof.

-8-

knowledge and has received full and complete copies from or on behalf of Owner. Property Manager shall not make payments on account of any ground lease, mortgage, deed of trust or other similar security instrument affecting the Property, if any, unless such payments are specifically identified in an Approved Operating Budget or an Approved Capital Budget, or unless Property Manager is otherwise specifically instructed to do so by Owner in writing.

2.2.13 Laws, Licenses and Permits.

All Licenses shall be obtained in Owner’s name whenever possible. Any Licenses obtained in the name of Property Manager shall be held on behalf of, and for the benefit of, Owner, and upon termination of this Agreement, Property Manager shall, to the extent such Licenses are transferable or assignable, transfer or assign all such Licenses (other than Property Manager’s real estate agent/broker licenses) to Owner or to such person as Owner may direct at no cost to Owner.

2.2.14 Notice and Cooperation in Legal Proceedings. Property Manager shall give prompt notice to Owner or Manager of the commencement of any action, suit or other legal proceeding (of which it has actual knowledge) against Owner, or against the Property with respect to the operations of the Property or otherwise affecting the Property.

Notwithstanding any provision of this Agreement to the contrary (a) Property Manager’s obligations under this Agreement which, by their nature, require the provision or payment of funds, fees, compensation or other payments to third party vendors, suppliers, contractors, workman and/or other parties (collectively, “Third Party Payments”) shall be conditional upon Owner providing on a timely basis adequate funds to cover all such Third Party Payments and (b) in no case shall Property Manager have any obligation to provide or cover any such Third Party Payments (or any portion thereof), and Property Manager shall have no liability whatsoever for failing to pay or cover from its own funds any such Third Party Payments.

2.2.18 Purchases. Property Manager shall supervise and purchase or arrange for the purchase of all inventories, provisions, supplies and operating equipment which are provided for in the Approved Operating Budget or otherwise specifically approved by Owner in writing.

which the Property is located, (c) lease or license space to any person in which Owner or DRT owns a ten percent (10%) or greater interest, directly or indirectly (by applying the constructive ownership rules set forth in Section 856(d)(5) of the Code, or (d) accept, or cause or allow to be earned, any payments or other amounts which would fail to qualify as “rents from real property” as described in Section 856(d) of the Code, in each case to the extent Property Manager is aware of such nonqualifying income or payment or advised of the same. Accordingly, Property Manager shall not provide any services giving rise to such nonqualifying income and shall not provide any new services related to the Property without the prior written consent of Owner, which consent may be withheld in Owner’s sole discretion. In the event Owner consents to the provision of any such non-customary services by Property Manager to any tenant or licensee of the Property, such services shall be provided by Property Manager at competitive rates and for its own account and neither Owner nor DRT, directly or indirectly, shall participate in the collection of or share in the revenues or profits derived from such services. Without limiting the generality of the foregoing, with respect to any of the services to be rendered by Property Manager for the Property, Property Manager agrees that it will not enter into any subcontract with or otherwise engage the services of any person from whom Owner or DRT, directly or indirectly, derives any revenue (including, for example, a tenant of the Property).
