This CONTRIBUTION AGREEMENT (this “Agreement”) is made and entered into as of October 13, 2004 (“Effective Date”), by and among THOMAS PROPERTIES GROUP, L.P., a Maryland limited partnership (the “Operating Partnership”), JAMES A. THOMAS, individually and as Trustee of the Lumbee Clan Trust (“Thomas” and a “Contributor”), each of the contributors listed on Exhibit “B” attached hereto (each also a “Contributor” and collectively with Thomas, the “Contributors”) and the other entities listed thereon.

RECITALS

A. As of the Effective Date, the Contributors hold, indirectly, all or a portion of the ownership interests in a portfolio of office and other properties located in California, Pennsylvania and Texas listed on Exhibit “B” to this Agreement (each a “Participating Property”).

B. Operating Partnership, Thomas and each other Contributor desire to enter into a series of transactions (the “Formation Transactions”) whereby the Operating Partnership will acquire all or a portion of each Contributor’s Participating Interests (as defined in Recital ”D” and individually set forth in Exhibit ”B”) in exchange for units of limited partnership interests (“Partnership Units”) in the Operating Partnership.

C. The Formation Transactions shall be consummated in conjunction with the proposed initial public offering (the “Public Offering”) of the common stock of Thomas Properties Group, Inc., a Delaware corporation (the “Company”), which is the sole general partner of the Operating Partnership.

D. The Formation Transactions will include the contribution to the Operating Partnership by each Contributor of all or a part of such Contributor’s Participating Interests (as defined below) described on Exhibit “B”, free and clear of all Liens, as a partner or member in each of the limited partnerships, limited liability companies or corporation (each an “Intermediary Owner”) listed on Exhibit “B” which, in turn, directly or indirectly own Property Interests in the Participating Properties as more fully described on Exhibit “B”. The direct ownership interest in each Participating Property (“Property Interest”) is owned by a limited partnership or limited liability company (each a “Property Owner”) one or more of which are also Intermediary Owners for purposes of this Agreement, as more fully described on Exhibit “B”. “Participating Interests” means, with respect to each Intermediary Owner, a Contributor’s rights and interests in such Intermediary Owner, as more fully set forth on Exhibit “B”, including without limitation, such Contributor’s voting rights and interests in the capital, profits and losses of such Intermediary Owner or any money or property distributable therefrom. The Participating Interests include the Contributor’s rights and interests in Thomas Development Partners, L.P., a California limited partnership (“TDPLP”), which shall be deemed to be an Intermediary Owner for purposes hereof.

E. Each Contributor acknowledges that the Operating Partnership may decide that, rather than acquiring the Participating Interests in an Intermediary Owner, or acquiring a Participating Interest by direct transfer, it is more desirable for the Operating Partnership to acquire a particular Participating Property by a direct contribution of the Property Interest in such

Participating Property from the Property Owner that owns such Participating Property (a “Direct Contribution”), or by a merger of a another Person or an Intermediary Owner with and into the Company, the Operating Partnership or an Affiliate of either of them (a “Merger”), or to divide an Intermediary Owner into more than one partnership and/or limited liability company to facilitate the Formation Transactions (a “Division”); and, so long as the Operating Partnership agrees to hold each Contributor harmless for any additional adverse tax consequences to such Contributor or additional costs or liabilities incurred by such Contributor as a result of any restructuring pursuant to this Recital ”E” as provided in Section 5.4, each Contributor desires to give the Operating Partnership the right, in the Operating Partnership’s sole discretion, to engage in any Direct Contribution, Merger or Division on the terms and conditions described herein without the need to seek any further consent or action of any Contributor, and will give hereby an irrevocable power of attorney as set forth in Article 6 and irrevocable consents as set forth in Section 5.4, subject to the terms and conditions of this Agreement.

F. The parties acknowledge that the Operating Partnership’s acquisition of the Participating Interests and the Contributor’s contribution of its Participating Interests is in connection with and is subject to the consummation of the Formation Transactions and the Public Offering. It is understood that the Operating Partnership may acquire interests in additional properties with the proceeds of 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:

1. CONTRIBUTION IN EXCHANGE FOR PARTNERSHIP UNITS.

1.1 Contribution of Participating 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, the Participating Interests listed on Exhibit “B”, including such Contributor’s rights and interests to the Intermediary Owners and all rights to indemnification in favor of such Contributor under the agreements pursuant to which such Contributor or its Affiliates acquired the Participating Interests. The contribution of each Contributor’s Participating Interests shall be evidenced by a Contribution and Assumption Agreement in substantially the form of Exhibit ”C” attached hereto. Furthermore, at the request of the Operating Partnership, each Contributor shall execute or shall cause each of its individual constituent partners and/or members (as applicable) to execute and have duly acknowledged an individual quitclaim deed for each Property in the form of Exhibit ”D” quitclaiming to the Operating Partnership any Property Interest in and to the Participating Properties. The parties shall take such additional actions and execute such additional documentation as may be required by each relevant Organizational Document and the Agreement of Limited Partnership of the Operating Partnership (the “OP Agreement”) or as requested in the reasonable judgment of counsel to the Operating Partnership in order to effect the transactions contemplated hereby.

1.2 Contribution of Other Assets.

At the Closing and subject to the terms and conditions contained in this Agreement:

(a) Contributors will cause TDP-Commerce Square Gen-Par, LLC and Philadelphia Plaza Associates to each assign to the Operating Partnership all of its respective right, title and interest in, under and to the Partnership Interest Purchase Agreement made and entered into as of March 1, 2004 with Prometheus Investment Holding, LLC and Prometheus Investment Holding, L.P. (the “OCS Purchase Agreement”) so that the Operating Partnership will have the right to purchase, or to cause Prometheus Investment Holding, LLC and Prometheus Investment Holding, L.P. to contribute to the Operating Partnership in consideration for a cash payment, all of their rights and interests in Commerce Square Partners-Philadelphia Plaza, L.P.; and

(b) Contributors will assign or cause their Affiliates to assign to the Operating Partnership all of their right, title and interest in, under and to any agreement with SFT I, Inc. (“Repayment Agreement”), pursuant to which the Series B Preferred Equity in Commerce Square Partners-Philadelphia Plaza, L.P. will be repaid at the Closing of the Offering; and

(c) Contributors will assign or cause their Affiliates to assign and transfer to the Operating Partnership all contracts, leases, employment agreements, and letters of intent to which TDPLP is a party or by which its assets are bound as of the date of the Formation Transaction (“TDPLP Contracts”); the foregoing assignment and transfer will either be effected by a separate assignment or by operation of law upon the contribution of the Participating Interests in TDPLP to the Operating Partnership and the dissolution of such entity. Contributors will assign or cause their Affiliates to assign and transfer to the Operating Partnership all furniture, fixtures and equipment owned by TDPLP as of the date of the Formation Transactions.

The OCS Purchase Agreement, the Repayment Agreement, the TDPLP Contracts and the Organizational Documents of each Intermediary Owner (as defined in Section 3.2(a)) are collectively referred to herein as the “Assumed Agreements”. The contribution or assignment of 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 “C” attached hereto. The parties shall take such additional actions and execute such additional documentation as may be required by the OP Agreement or as requested in the reasonable judgment of counsel to the Operating Partnership in order to effect the transactions contemplated hereby.

1.3 Excluded Assets; One Commerce Square and Two Commerce Square.

(a) The parties expressly acknowledge and agree that all assets and properties of TDPLP shall be contributed to the Operating Partnership except only for those assets described on Schedule 1.3 attached hereto (such assets listed on Schedule 1.3 are referred to herein as the “Excluded Assets”).

(b) With respect to One Commerce Square and Two Commerce Square in Philadelphia, the Participating Interests represent 89% of the profits and losses and 89% of the capital interests in each of such Property Owner. Therefore, the Operating Partnership will, upon

completion of the Formation Transactions, own, directly or indirectly, 89% of the profits and losses and capital of both One Commerce Square and Two Commerce Square. As a material part of the Formation Transactions, and as an incentive for the Operating Partnership to enter into this Contribution Agreement, upon the consummation of the Formation Transactions, the Contributors shall cause the owners of the remaining 11% interest in each of One Commerce Square and Two Commerce Square (“11% Interests”) to enter into an Amended and Restated Partnership Agreement for Commerce Square Partners-Philadelphia Plaza, L.P. and a Fourth Amendment to Partnership Agreement for Philadelphia Plaza-Phase II (collectively, “Commerce Square Partnership Amendments”) as well as a separate agreement with the Operating Partnership in the form of Exhibit ”J” attached hereto (“Pooling Agreement”). The Commerce Square Partnership Amendments shall provide that upon a capital event (as defined in each Commerce Square Partnership Amendment) each Intermediary Owner of an interest in One Commerce Square and Two Commerce Square that is owned, directly or indirectly, by the Operating Partnership will have a priority over the owner of the 11% Interest in One Commerce Square and Two Commerce Square to receive a distribution of its entire capital account in each Property Owner that owns One Commerce Square or Two Commerce Square, including the original capital accounts of the Contributors of such interests, any additional capital contributed to such Intermediary Owner by the Operating Partnership, and in the case of One Commerce Square, including the capital being paid by the Operating Partnership to Prometheus Investment Holding, LLC and Prometheus Investment Holding, L.P under the OCS Purchase Agreement (which shall be deemed to have been contributed by the Operating Partnership to Commerce Square Partners-Philadelphia Plaza, L.P. and then distributed to Prometheus Investment Holding, LLC and Prometheus Investment Holding, L.P. in liquidation of their partnership interests), together with a preferred return on such outstanding capital account balances (“Preferred Return”) at the rate of 8% per annum from the closing of the Formation Transactions through the first anniversary thereof, 9% per annum from the first anniversary of the closing of the Formation Transactions through the second anniversary thereof, 10% per annum from the second anniversary of the closing of the Formation Transactions through the third anniversary thereof, 11% from the third anniversary of the closing of the Formation Transactions through the fourth anniversary thereof, and 12% from the fourth anniversary of the closing of the Formation Transactions through the date on which each such Intermediary Owner has received a distribution of its entire capital account balance in such Property Owner. The Pooling Agreement shall require that the Preferred Return is calculated and paid to the Intermediary Owners owned by the Operating Partnership on a cumulative basis for both One Commerce Square and Two Commerce Square prior to a return of capital or distributions of capital event proceeds to the owners of the 11% Interests in either One Commerce Square or Two Commerce Square.

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 TDPLP and its Affiliates and shall thereafter pay, perform or discharge in accordance with their terms all of the liabilities and obligations of TDPLP and its Affiliates listed on Schedule 1.4 attached hereto (the “Assumed Liabilities”). All liabilities of TDPLP other than the Assumed Liabilities are collectively referred to as the “Excluded Liabilities”.

1.5 Consideration and Exchange of Partnership Units.

Subject to Section 1.6, the Operating Partnership shall, in exchange for the Participating Interests, the Assumed Liabilities and the Assumed Agreements, transfer to each Contributor the aggregate number of Partnership Units having a value, based on one Partnership Unit being equal in value to the Public Offering price for one share of the Company’s common stock, equal to the value of such Contributor’s Total Consideration for each Participating Interest indicated on Exhibit “B”. The transfer of the Partnership Units to each Contributor shall be evidenced by either an amendment (the “Amendment”) to the OP Agreement or by certificates relating to such Partnership Units (the “Certificates”) in either case, as determined by the Operating Partnership, in accordance with the OP Agreement. The parties shall take such additional actions and execute such additional documentation as may be required by the relevant Intermediary Owner Agreements and the OP Agreement in order to effect the transactions contemplated hereby.

1.6 Adjusted Consideration.

The Operating Partnership reserves the right not to acquire any particular interest that constitutes part of the Participating Interests, if in good faith the Operating Partnership determines that it would be inappropriate for the Operating Partnership to own the underlying Participating Property. Each Contributor hereby agrees that, in such event, such Contributor’s Total Consideration as indicated on Exhibit “B” may be reduced by an amount determined in accordance with Exhibit “B”.

The risk of loss relating to each Contributor’s Participating Interests and the underlying Participating Properties prior to Closing shall be borne by such Contributor. If, prior to the Closing, any Participating Property is partially or totally destroyed or damaged by fire or other casualty, or is taken by eminent domain or through condemnation proceedings, then the Operating Partnership may, at its option, determine not to acquire a particular Participating Property, including Contributor’s interest in the Intermediary Owner that directly or indirectly owns such Participating Property, that has been partially or totally destroyed, damaged or taken. Under such circumstances, Contributor acknowledges that the Total Consideration will likely be correspondingly reduced. After the occurrence of any such casualty or condemnation affecting a Participating Property, the Operating Partnership may also, at its option, elect to (a) acquire Contributor’s interest in any such Intermediary Owner that directly or indirectly owns the affected Participating Property, (b) direct Contributor to pay or cause to be paid to the Operating Partnership any sums collected under any policies of insurance or award proceeds relating to such casualty or condemnation and otherwise assign to the Operating Partnership all rights to collect such sums as may then be uncollected, and (c) adjust or settle any insurance claim or condemnation proceeding. Under such circumstances, such Contributor’s Total Consideration shall be reduced by its pro rata share of the amount of any deductibles or shortfalls under the applicable insurance policies or award, plus all costs of collection. Insurance on the transferred Participating Interests and the Participating Properties shall be assigned to the Operating Partnership at the Closing. If a Participating Property constituting more than 25% of the total value of the Participating Properties is partially or totally damaged or condemned, the Operating Partnership may elect, by notice to the Contributors given within twenty (20) days after the date of such damage or condemnation, to terminate this Agreement, in which case neither the Contributors nor the Operating Partnership shall have any further rights or obligations under this Agreement.

1.7 Tax Treatment of Transaction.

The transfer, assignment and exchange effectuated pursuant to this Agreement shall constitute a “Capital Contribution” to the Operating Partnership pursuant to the OP Agreement and is intended to be governed by Section 721(a) of the Code and each Contributor (or such other transferor) hereby consents to such treatment.

1.8 Allocation of Total Consideration.

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

1.9 Term of Agreement.

If the Closing does not occur by December 31, 2004 (the “Termination Date”), this Agreement shall be deemed terminated and shall be of no further force and effect and neither the Operating Partnership nor Contributor shall have any further obligations hereunder except as specifically set forth herein.

1.10 Final Year Allocations.

To the extent an Intermediary Organizational Agreement does not provide for final year tax allocations, the parties hereto agree to use the “interim closing of the books” method as provided in Section 706 of the Code to allocate income and loss for the year.

1.11 Sale Limitations and Debt Guarantees.

In connection with the Formation Transactions, the Operating Partnership has agreed to certain limitations on its ability to sell its direct or indirect interests in One Commerce Square and Two Commerce Square in Philadelphia, Pennsylvania, and to use commercially reasonable efforts to make certain secured mortgage debt available to be guaranteed by each Contributor, as set forth on Exhibit “F”. The Operating Partnership’s liability to comply with such obligations is solely set forth in Exhibit “F” and will not be subject to Section 3.4.

1.12 Pre-Closing Transactions.

Attached to Schedule 1.12 is a schedule of intercompany obligations of TDPLP, its Affiliates, and certain individuals and other entities, as of , 2004 (the “Intercompany Schedule”). Contemporaneously with or prior to the Closing Date, all accounts receivable or payable from or to an Intermediary Owner or Entity that will be owned in whole (denoted by “I” on the attached Intercompany Schedule) or in part (denoted by “%”on the attached Intercompany

Schedule), directly or indirectly, by the Operating Partnership upon consummation of the Formation Transactions, on the one hand, to or from a partnership, entity or Thomas or his Affiliates that will not be owned in whole or in part, directly or indirectly, by the Operating Partnership upon consummation of the Formation Transactions (denoted by “0” on the attached Intercompany Schedule), on the other hand, will be contributed/distributed, contributed, paid, merged, satisfied, written-off or forgiven, to the extent such action would be shown on an intercompany schedule updated as of the Closing Date, based on the principles used in and the method of preparation of the Intercompany Schedule as attached hereto (the “Closing Intercompany Schedule”). Notwithstanding anything to the contrary in this Agreement, the Operating Partnership shall have no right to acquire, directly or indirectly, any receivable that will result in a direct or indirect extension of credit, in the form of a personal loan, to or for any director or executive officer of the Company within the meaning of Section 402 of the Sarbanes-Oxley Act of 2002, and any such receivable not previously satisfied or distributed shall be deemed to have been distributed by the relevant Intermediary Owner to its owners immediately prior to the Closing, or if necessary, shall be forgiven effective as of the Closing. Contributors each acknowledge that no accounts payable, that the Operating Partnership, directly or indirectly, will assume immediately following consummation of the Formation Transactions, after taking into account all contributions, distributions, payments, mergers, satisfactions, write-offs or other forgiveness, will be owed to Thomas or any of his Affiliates (including the other Contributors).

1.13

Limited Voting Stock.

The Certificate of Incorporation of the Company has authorized the issuance of Limited Voting Stock Shares (“Limited Voting Stock”). In return for a payment of $166,667 to the Company, the Company has issued shares of Limited Voting Stock to Thomas and the other Contributors which are equal to the number of Partnership Units that will be issued to such Contributors on the Closing of the Formation Transactions. Thomas has further agreed, on the Closing of the Formation Transactions, to contribute to each affiliated Contributor a number of shares of Limited Voting Stock equal to the number of Partnership Units issued to such Contributor, so that each Contributor, including Thomas, will end up holding OP Units paired with an equal number of shares of Limited Voting Stock which will be governed by the terms and conditions of that certain Pairing Agreement (“Pairing Agreement”) between the Company and the Operating Partnership dated as of October 13, 2004. Each Contributor acknowledges and agrees that the Limited Voting Stock owned by such Contributor is not transferable other than as permitted by the Pairing Agreement and that any transfer of the Partnership Units that is otherwise permitted under the OP Agreement will also require the transfer of a like number of shares of the Limited Voting Stock owned by such Contributor so that there is no circumstance under which such Contributor holds shares of the Limited Voting Stock without holding the equivalent number of OP Units. Any such transfer of Partnership Units without an equal number of shares of Limited Voting Stock shall cause such paired shares of Limited Voting Stock to be automatically redeemed and cancelled.

2. CLOSING.

2.1 Conditions Precedent.

The effectiveness of the Company’s registration statement to be filed with the Securities and Exchange Commission on Form S-11 (the “Prospectus”) after the execution of this Agreement is a condition precedent to the obligations of all parties to this Agreement to effect the transactions contemplated by this Agreement on the Closing Date (as defined below).

(g) An affidavit from each Contributor, stating under penalty of perjury, such Contributor’s United States Taxpayer Identification Number and that such Contributor is not a foreign person pursuant to Section 1445(b)(2) of the Code and a comparable affidavit satisfying California and any other withholding requirements;

(h) Any other documents reasonably requested by the Operating Partnership or reasonably necessary or desirable to assign, transfer, convey, contribute and deliver such Contributor’s Participating Interests or, if the Operating Partnership elects, the Properties directly, free and clear of all Liens (subject to the Permitted Liens if the Properties are transferred directly) and effectuate the transactions contemplated hereby, including, without limitation, and only to the extent applicable, quitclaim deeds and/or grant deeds (if transferred directly), assignments of ground leases, space leases, bills of sale, assignments, and such documents as may be necessary to enable one or more title insurance companies (acceptable to the Operating Partnership in its sole discretion) to issue to the Operating Partnership at Closing ALTA owner’s policies of title insurance with such endorsements as the Operating Partnership may reasonably request (including, without limitation, non-imputation endorsements to the extent available) with an aggregate of one hundred percent (100%) coverage for each of the Properties (with a tie-in endorsement with respect to the Properties located in California) and levels of reinsurance for the Properties as are reasonably acceptable to the Operating Partnership, insuring fee simple and/or leasehold title to all real property and improvements comprising all or any part of the Participating Properties to the Operating Partnership as the Operating Partnership may designate, subject only to the Permitted Liens (collectively, the “Title Policies”), and all state and local transfer tax returns and any filings with any applicable governmental jurisdiction in which the Operating Partnership is required to file its partnership documentation or the recording of the Contribution and Assumption Agreement or deed or other Property Interests transfer documents is required;

(i) If requested by the Operating Partnership, certified copies of all organizational documents for each Contributor that is an entity, together with certified copies of all appropriate corporate resolutions, member consents or partnership actions authorizing the execution, delivery and performance by each Contributor of this Agreement, any related documents and the documents listed in this Section 2.3; and

(j) Estoppel certificates from the tenants listed on Schedule 2.1(e), substantially in the form of Exhibit “H” attached hereto.

2.4 Closing Costs.

The Operating Partnership shall pay all escrow charges, title charges and recording taxes or fees and any other closing costs incurred in connection with the transactions contemplated hereby; provided, however, the Operating Partnership shall pay the first One Million Dollars ($1,000,000), in the aggregate, of any documentary transfer taxes arising out of the Formation Transactions and the Contributors shall be responsible to pay any documentary transfer taxes arising out of the Formation Transactions in excess of the first $1,000,000 of such taxes. Each Contributor shall be responsible for its own legal costs, and the Operating Partnership shall be responsible for its own legal costs, in connection with this Agreement and the Formation Transactions. This section shall survive the Closing of the Formation Transactions.

2.5 Prorations; Net Current Assets.

The revenues and expenses from each Participating Property will be prorated on a per diem basis as of the date prior to the Closing of the Formation Transactions (“Proration Date”) based on the actual number of days in the month in which such Closing occurs. At the Closing, the Contributors and the Operating Partnership shall determine the net current assets of each Property Owner and each Intermediary Owner allocable to periods prior to the Closing Date after deducting the net current liabilities of such Property Owner and Intermediary Owner, as applicable, allocable to such period using generally accepted accounting principles (such excess of net current assets over net current liabilities is referred to herein as the “Property Owner’s Net Current Assets”). At the Closing, the applicable Contributor shall receive additional Partnership Units equal in value to the Property Owner’s Net Current Assets; conversely, if on the Closing, the Property Owner’s or Intermediary Owner’s net current liabilities exceed such Property Owner’s or Intermediary Owner’s net current assets, the applicable Contributor shall either pay such excess amount of liabilities to the Intermediary Owner (which amount will be contributed to the Property Owner if the excess liabilities are at the Property Owner level) or the number of Partnership Units to be issued upon the Closing to such Contributor shall be reduced by an amount equal in value to the amount of such excess liabilities.

For purposes of this Section 2.5, the following approach shall be used to calculate the Property Owner’s Net Current Assets for each Participating Property, which amounts shall be calculated as of the Proration Date:

(a) Expenses. Except as set forth in subsection (e) below, all items which are considered expenses under generally accepted accounting principles, including, but not limited to, real estate and personal property taxes (excluding any such taxes paid directly to the taxing authority by a tenant), utilities, license, permit and other fees, management fees and reimbursements, maintenance costs, payments due under leases or operating agreements or reciprocal easement agreements at a Participating Property and other operating expenses, and are allocable to periods prior to the Proration Date but are unpaid shall be deducted in calculating the Property Owner’s Net Current Assets. Any expense which is allocable to a period both before and after the Proration Date shall be allocated ratably on a per diem basis for the period to which it applies.

(b) Debt Service. All interest payable under any loans that are currently in existence with respect to any Participating Property that will remain in effect following the Closing Date shall be pro rated on a per diem basis as of the Proration Date and the allocated interest owed for the period before the Proration Date that has not yet been paid as of the Proration Date shall be a net current liability of the applicable Property Owner, while any prepaid interest allocable to the period after the Proration Date shall be considered a current asset in calculating the Property Owner’s Net Current Assets. Any amortization of the principal balance of any existing loans owed by any Entity with respect to the Participating Properties which is paid after December 31, 2003 and prior to the Closing Date shall be added back into current assets in the calculation of Property Owner’s Net Current Assets.

(c) Rent and Other Revenues. All rent payable pursuant to leases of a Participating Property (except for (i) amounts more than 30 days in arrears or (ii) payable by a

tenant in bankruptcy or out-of-possession who is not current on all payments due to the Property Owner) with respect to a Participating Property (other than percentage rents) and all other income of the Property Owners which is allocable to periods prior to the Closing Date and not previously paid to the Property Owners shall be considered a current asset of the Property Owner, except for all unapplied cash security deposits and interest thereon, if any, made by tenants under such leases which are payable to such tenants pursuant to law or the applicable leases. All rent paid pursuant to leases of a Participating Property prior to the Proration Date which is allocable to periods prior to and after the Proration Date (including all such rents paid for the month in which the Proration Date occurs) and all amounts payable by tenants for utility costs, operating expenses, insurance costs and real estate taxes, including tenant contributions for unbilled real estate taxes which are to be paid after the Proration Date (collectively, “Expense Contributions”) shall be allocated ratably over the period to which they apply on a per diem basis for the expenses to which they apply and to the extent allocable to the period prior to the Proration Date shall be considered a current asset in calculating the Property Owner’s Net Current Assets. The Property Owner’s Net Current Assets shall include accounts receivable of the Property Owners as of the Proration Date with respect to any tenant-in-occupancy who is not in arrears for more than 30 days and who is not in bankruptcy, after deducting a reasonable reserve therefor.

(d) Percentage Rents. The Property Owner’s Net Current Assets shall include a pro rata portion of percentage rents payable from tenants under leases in existence prior to the Proration Date allocable to the lease year which began before the Proration Date and which ends after the Proration Date, with the pro rata portion being equal to the product of (i) the amount of such percentage rent payable by such tenant, and (ii) a fraction, the numerator of which is the number of days in such lease year prior to and including the Proration Date and the denominator of which is 365.

(e) Tenant Allowances and Commissions All unpaid tenant allowances, including tenant improvement allowances, landlord contributions, lease takeover obligations and other payments to or for the benefit of tenants and periods of free rent after the Proration Date, and unpaid lease commissions applicable to leases in effect at the Participating Properties as of the Proration Date shall not be considered current liabilities and shall not be deducted in calculating the Property Owner’s Net Current Assets.

(f) Cash Reserves. The Property Owners’ Net Current Assets will include any cash reserves and/or escrow deposits for real property taxes and assessments, insurance premiums or other items made with or held by any lender under an existing loan on a Participating Property, after deducting any allocation of the underlying expense as of the Proration Date for which the reserve in question is held, together with so much of any interest earned on the reserve and/or escrow deposit as is properly attributable to the allocated amount thereof; provided, however, no allocation shall be made for casualty or condemnation proceeds held by the lender under any mortgage or deed of trust.

(g) Security Deposits. At the Closing, Contributors shall provide the Operating Partnership with a current schedule of the unapplied portions of all security deposits that have been paid to each Property Owner or are held by agents of the Property Owners on their behalf (or that were deposited with any predecessor in interest of such Property Owners to

the extent that such predecessor has turned over such security deposit to the Property Owner or given the Property Owner credit therefor) by any tenants. The Property Owners shall retain the security deposits held by them and the Contributors shall not have any further interests in or rights to the security deposits from and after the Closing Date. The Operating Partnership shall indemnify, defend and hold the Contributors harmless from any and all claims, liabilities, costs and expenses (including reasonable legal fees and costs) imposed upon or incurred by the Contributors with respect to any security deposits held by the Property Owners or applied by the Property Owners after the Closing. The Property Owner’s Net Current Assets shall include any interest accrued on the security deposits as of the Proration Date except to the extent such interest is required by law or the leases to be paid to the tenant.

(h) Final Adjustment. The Contributors and the Operating Partnership shall use reasonable efforts to accurately estimate the apportionments on the Proration Date and agree to re-prorate the foregoing items once the actual financial data has been received from each Property Owner and is complete. Within six months after the Closing Date, the Contributors and the Operating Partnership shall agree on final apportionments based on the actual financial data from the Property Owners. All adjustments, if any, shall be made either by issuing additional Partnership Units to the Contributor or by the Contributor returning Partnership Units (together with any dividends received thereon), in each case equal to the amount of such adjustment based on the initial public offering price of the common stock of the Company, following such re-proration.

(i) Collection of Arrearages. Any payment of rents or other income collected after the Closing Date will be applied (i) first to sums due from the paying tenant for the month in which the Closing Date occurs, (ii) second, to sums first coming due following the month in which the Closing Date occurs and that are due from the tenant at the time a payment is received subsequent to the Closing Date until such sums have been paid in full, and (iii) third, to the amounts due from the paying tenant (in chronological order), regardless of any contrary designation by such tenant, which amount shall be remitted by the Operating Partnership, as an agent of the Contributor, to the applicable Contributor if such delinquent rent or other payment relates to a period prior to the Closing Date and was not included in calculating the Property Owner’s Net Current Assets. The Operating Partnership shall cause each Property Owner to use commercially reasonable efforts, without commencing litigation, to collect any rent arrearages that exist as of the Closing Date that were not included in calculating the Property Owner’s Net Current Assets; provided, however, that if the Contributors agree to pay for the costs of any litigation, and if such rent arrearage is over $25,000, the Operating Partnership shall cause the relevant Property Owner to commence and prosecute such litigation as is required to collect such arrearage, subject to limitations imposed by law and any bankruptcy stay. If the delinquent tenant is no longer in possession of its premises and the delinquent rent was not included in the calculation of the Property Owner’s Net Current Assets, the Contributor may pursue such tenant directly for the arrearages and the Operating Partnership will cause the Property Owner to provide all relevant documents and records in its possession to facilitate such collection action and will assign to such Contributor any claim it may have to such delinquent rent. The Operating Partnership will not settle any claims with respect to such amounts relating to the period prior to the Closing Date that were not included in the calculation of Property Owner’s Net Current Assets without the Contributors’ prior written consent (which consent will not be unreasonably withheld or delayed). Collection costs shall be a first charge against any amount collected before any recovered sums are allocated between the Contributors and the Property Owners, as provided in this Section 2.5.

(j) Partial Property Ownership. Notwithstanding any contrary provision hereof, except as set forth in subsection (g) with respect to security deposits, in the case of One Commerce Square, Two Commerce Square, 2121 Market Street, El Segundo Campus, Arco Plaza and any other partially owned Participating Properties, where the Contributors are contributing less than 100% of the ownership interests in such Participating Properties, the apportionments of revenues and expenses and the calculation of Property Owners’ Net Current Assets shall be adjusted to reflect the percentage of each such property that is being contributed to the Operating Partnership upon the Closing. The owners of the 11% Interests shall retain their pro rata share of all revenues on such Participating Properties and shall be responsible for paying their pro rata share of all expenses for such properties after the apportionment provided for herein and shall be entitled to their prorate share of the Property Owners’ Net Current Assets, subject only to the applicable terms and provisions of the Organizational Document of such Property Owner or Intermediary Owner.

(k) Inspection of Books and Records. The Contributors shall have the right from time to time to inspect and copy, during normal business hours, the books and records of each Property Owner and the Operating Partnership, and on reasonable advance notice, to audit such books and records relating to the period before and the calendar year in which the Closing Date occurs.

This section shall survive the Closing of the Formation Transactions.

2.6

Spousal Consents.

Concurrent with the execution of this Agreement, each Contributor that is a married individual shall deliver a Spousal Consent executed by such individual’s spouse and in the form of Exhibit ”I” attached hereto.

3. REPRESENTATIONS AND WARRANTIES AND INDEMNITIES.

3.1 Representations and Warranties of the Operating Partnership.

(e) Knowledge of Properties. Except for the express written representations of the Contributors set forth in this Agreement, the Operating Partnership is relying upon its own independent analysis and assessment, and the advice of such the Operating Partnership’s advisors, and not upon that of a Contributor or any of a Contributor’s Affiliates, for purposes of evaluating, entering into, and consummating the transactions contemplated by this Agreement.

(f) No Violation.

(g) Partnership Units. The Partnership Units to be issued to each Contributor pursuant to this Agreement will have been duly authorized and, when issued against the applicable Total Consideration, will, subject to the terms of the OP Agreement, be validly issued to such Contributor by the Operating Partnership free and clear of all Liens created by the Operating Partnership, other than any such Liens created pursuant to the OP Agreement.

As of the Effective Date, the Operating Partnership has delivered to each Contributor or each Contributor’s counsel the OP Agreement, which is in substantially the form in which it will be executed by the parties at the Closing, other than for such changes that may be made after the Effective Date that are not disproportionately adverse to one or more Contributors.

(i) Material Agreements. None of the execution, delivery or performance of this Agreement, any agreement contemplated hereby between the parties to this Agreement and the transactions contemplated hereby between the parties to this Agreement 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 a Contributor of any material agreement, document or instrument to which the Operating Partnership is a party or by which its property or interests are bound.

3.2 Representations and Warranties of the Contributors.

Each Contributor jointly and severally represents and warrants to the Operating Partnership as set forth below (subject in each case to qualification by the disclosures in the disclosure schedule attached hereto as Schedule 3.2 (the “Disclosure Schedule”) and the Prospectus, including, without limitation, any matters for which a reserve has been established as reflected in the pro forma financial statements contained in the Prospectus), which representations and warranties are true and correct as of the date hereof and will (except to the extent relating to a specified date) be true and correct as of the date of Closing. Each Contributor acknowledges and agrees to be bound by the indemnification provisions contained in Section 3.4. Each Contributor hereby agrees to give the Operating Partnership prompt written notice of any information which makes any representation or warranty made by such Contributor hereunder on the date hereof untrue, and in any event no later than five (5) business days of obtaining such information.

(a) Organization: Authority: Qualification. Each Contributor if a natural person, has the legal capacity to enter the Agreement, each agreement contemplated hereby and to carry out the transactions contemplated hereby; if not a natural person, such Contributor is duly formed, validly existing and in good standing (to the extent applicable) under the laws of the jurisdiction of its formation and of each jurisdiction in which it is required to be qualified to do business. Each Contributor has all requisite power and authority to enter this Agreement, each agreement contemplated hereby and to carry out the transactions contemplated hereby, and 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. Each Intermediary Owner and Property Owner is duly formed, validly existing and in good standing (to the extent applicable) under the laws of the jurisdiction of formation and each Intermediary Owner and Property Owner has the requisite power and authority to carry on its business as it is presently conducted and, to the extent required under applicable law, is qualified to do business in each jurisdiction in which the nature of its business or the character of its property make such qualification necessary, except where failure to be so qualified would not have a material adverse effect on the assets, business or financial condition of such Intermediary Owner or Property Owner. The general partner, managing member or administrative member of each Intermediary Owner or Property Owner has delivered to the Operating Partnership true and correct copies of each entity’s organizational documents, with all amendments as in effect on the date of this Agreement (collectively, the “Organizational Documents”). The Disclosure Schedule lists each Intermediary Owner and Property Owner, its jurisdiction of formation and each partner, member or other equity owner of such entity as of the date hereof. The Disclosure Schedule lists the percentage interest of the Contributors and any third party holders of interests (direct or indirect) in each Intermediary Owner and in each Property Owner as of the date hereof.

(b) Due Authorization. The execution, delivery and performance of this Agreement by each Contributor has been duly and validly authorized by all necessary action of each Contributor. This Agreement and each agreement, document and instrument executed and delivered by or on behalf of each Contributor pursuant to this 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.

(c) Consents and Approvals. Except as shall have been satisfied prior to the Closing Date and, for informational purposes as set forth in 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 or any Intermediary Owner or Property Owner 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 Company, the Operating Partnership and their subsidiaries, taken as a whole (a “Material Adverse Effect”).

(d) Ownership of the Participating Interests. The Participating Interests listed on Exhibit “B” attached hereto constitute all of the issued and outstanding interests owned (directly or indirectly) by the Contributors in the Intermediary Owners as of the Closing Date, other than the Excluded Assets, and therefore, constitute or will constitute as of the Closing Date all of the Contributors’ indirect interests in each Property Owner in each Participating Property (except for the Contributor’s interests in the 11% interests retained in One Commerce Square and Two Commerce Square). Each Contributor is the sole owner of its Participating Interests, beneficially and of record free and clear of any Liens of any nature, except as set forth in the Disclosure Schedule, and has full power and authority to convey the Participating Interests free and clear of any Liens, and, upon delivery of consideration for such Participating Interests as herein provided, the Operating Partnership will acquire good and valid title thereto, free and clear of any Liens except Liens created in favor of the Operating Partnership by the transactions contemplated hereby. Except as set forth in the Disclosure Schedule or for those to be acquired by a Contributor or the Operating Partnership, or relinquished, in connection with the Formation Transactions, there are no rights to purchase, subscriptions, warrants, options, conversion rights, preemptive rights, agreements, instruments or similar understandings of any kind outstanding (i) relating to the Participating Interests, any Property Interests, any interest in any Intermediary Owner or Property Owner, or (ii) to purchase, transfer or to otherwise acquire, or to in any way encumber, any of the interests which comprise the Participating Interests, any Property Interests, any interest in any Intermediary Owner or Property Owner, or any securities or obligations of any kind convertible into any of the interests which comprise the Participating Interests, any Property Interests, any interest in any Intermediary Owner or Property Owner, or other equity interests or profit participation of any kind in any of the Intermediary Owners or Property Owners. Except as contemplated in connection with the Formation Transactions or as permitted by Section 4.1(b)(2) of this Agreement, none of the Contributors will consent or participate in or in any way cause the transfer of any Property Interest, Participating Interest, any interest in any

Intermediary Owner or Property Owner, prior to the Closing. Except as set forth in the Disclosure Schedule, none of the Contributors has an equity interest, either direct or indirect, in the Participating Properties, except for the Participating Interests which are the subject of this Agreement and except for the Excluded Assets. Except as contemplated in the Formation Transactions or as otherwise disclosed in the Disclosure Schedule, none of the Contributors has any commitment or legal obligation, absolute or contingent, to any other Person other than the Operating Partnership to sell, assign, transfer or effect a sale of any right, title or interest in or to any of the Participating Interests, Property Interests, or interests in any Intermediary Owner or Property Owner.

(e) No Violation. Except as shall have been cured, consented to or waived in writing by the Operating Partnership prior to the Closing Date, none of the execution, delivery or performance of this Agreement, any agreement contemplated hereby and the transactions contemplated hereby and thereby does or will, with or without the giving of notice, lapse of time, or both, (i) 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 Operating Partnership of (A) the organizational documents, including the charters and bylaws, if any, of any Contributor or any Intermediary Owner or Property Owner, (B) any agreement, document or instrument to which any Contributor is a party or by which any Contributor, the Participating Interests, Property Interests (if any), or any Intermediary Owner or Property Owner are bound or (C) to Contributors’ Knowledge, 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 any Intermediary Owner or Property Owner or by which any Contributor, Intermediary Owner or Property Owner 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 or (ii) result in the creation of any Lien upon any of the Participating Interests, or any Intermediary Owner or Property Owner, or any interests therein. Except as shall have been cured, consented to or waived prior to the Closing Date or as set forth in the Disclosure Schedule, none of the Contributors or, to Contributors’ Knowledge, any Intermediary Owner or Property Owner is in violation of its Organizational Documents.

(f) Non-Foreign Status. Each Contributor is a United States person (as defined in Section 770 l(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(g) of this Agreement.

(g) Withholding. Each Contributor shall execute at Closing such certificates or affidavits reasonably necessary to document the inapplicability of any federal or state withholding provisions, including without limitation those referred to in clause (f). 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.

(h) Investment Purposes. Each Contributor acknowledges his, her or its understanding that the offering and issuance of the Partnership Units and shares of Limited Voting Stock (if applicable) to be acquired pursuant to the Agreement are intended to be exempt from registration under the Securities Act of 1933, as amended and the rules and regulations in effect thereunder (the “Act”) and that the Operating Partnership’s reliance on such exemptions is predicated in part on the accuracy and completeness of the representations and warranties of such Contributor contained herein. In furtherance thereof, each Contributor represents and warrants to the Company as follows:

(1) Investment. Each Contributor is acquiring the Partnership Units and any Limited Voting Stock solely for his, her or 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. Each Contributor agrees and acknowledges that he, she or it will not, directly or indirectly, offer, transfer, sell, assign, pledge, hypothecate or otherwise dispose of (hereinafter, “Transfer”) any of the Partnership Units or Limited Voting Stock 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. The term “Transfer” shall not include any redemption of the Partnership Units or exchange of the Partnership Units for Common Stock pursuant to the OP Agreement. Notwithstanding the foregoing, no Transfer shall be made unless it is permitted under the OP Agreement.

(2) Knowledge. Each Contributor is knowledgeable, sophisticated and experienced in business and financial matters; each Contributor 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 his, her or its investment in the Partnership Units; each Contributor has received and reviewed all information and documents about or pertaining to the Company that have been prepared as of the date hereof, 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, is familiar with the 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 Participating 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 his, her or its investment in the Partnership Units and to conduct its own independent valuation of the Participating Properties; and each Contributor understands and has taken cognizance of all risk factors related to the purchase of the Partnership Units. Each Contributor is a sophisticated real estate investor. Each Contributor is relying upon its own independent analysis and assessment (including with respect to taxes), and the advice of each Contributor’s advisors (including tax advisors), and not upon that of the Operating Partnership or any of the Operating Partnership’s Affiliates, for purposes of evaluating, entering into, and consummating the transactions contemplated by this Agreement.

(3) Holding Period. Each Contributor acknowledges that he, she or it has been advised that (i) the Partnership Units and the common stock of the Company into which the Partnership Units may be exchanged in certain circumstances (the “Common Stock”) must be held indefinitely, 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. Each Contributor further acknowledges that he, she or it has been advised that the Limited Voting Stock must be held indefinitely with the Partnership Units and that such Limited Voting Stock is not transferable except together with an equal number of Partnership Units as permitted by the Pairing Agreement and a notation shall be made in the appropriate records of the Company indicating that the Limited Voting Stock is subject to restrictions on transfer.

(4) Accredited Investor. Each Contributor is an “accredited investor” (as such term is defined in Rule 501(a) of Regulation D under the Act).

(5) Legend. Each certificate representing 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 Partnership Units issued in the Formation Transactions will include the following additional legend:

ANY TRANSFER OF THESE PARTNERSHIP UNITS SHALL BE SUBJECT TO THE RESTRICTIONS ON TRANSFER SET FORTH IN THE PAIRING AGREEMENT, A COPY OF WHICH MAY BE OBTAINED FROM THE GENERAL PARTNER ON REQUEST AND WITHOUT CHARGE.

The certificates representing shares of Limited Voting Stock shall bear a legend in substantially the following form:

ANY TRANSFER OF THE LIMITED VOTING STOCK REPRESENTED BY THIS CERTIFICATE SHALL BE SUBJECT TO THE RESTRICTIONS ON TRANSFER SET FORTH IN THE PAIRING AGREEMENT, A COPY OF WHICH MAY BE OBTAINED FROM THE COMPANY ON REQUEST AND WITHOUT CHARGE.

(i) No Brokers. Except as set forth in 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 and each Contributor shall indemnify and hold harmless the Operating Partnership for all costs and expenses (including reasonable attorneys’ fees) incurred by the Operating Partnership as a result of a breach of this representation. The provisions of this clause (i) shall survive the expiration or sooner termination of this Agreement.

(j) Solvency. Each Contributor and each Intermediary Owner and Property Owner has been and will be solvent at all times prior to and immediately following the transfer of the Participating Interests to the Operating Partnership.

(k) Taxes. To the Contributors’ Knowledge, the transactions contemplated hereby will not result in any current income tax liability to any Intermediary Owner or Property Owner, the Company or the Operating Partnership, and 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 due and has been properly reserved for payment by the Property Owners or tax liens or other charges which individually or in the aggregate would not have a Material Adverse Effect. 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 real property tax bills for such tax year actually received by any Holder or such Holder’s agents for the Property. For Federal income tax purposes, each Intermediary Owner or Property Owner is, and at all times during its existence has been, an S Corporation, partnership or limited liability company taxable as a partnership (rather than an association or a publicly traded partnership taxable as a corporation). Each Intermediary Owner or Property Owner has timely and properly filed all tax returns required to be filed by it and has timely paid all taxes required to be paid by it. Except as may be set forth in the Disclosure Schedule, none of the tax returns filed by any Intermediary Owner or Property Owner is the subject of a pending or ongoing audit, and no federal, state, local or foreign taxing authority has asserted any tax deficiency or other assessment against a Property or an Intermediary Owner or Property Owner. Each Intermediary Owner and Property Owner (other than Thomas SPE Corp. with respect to 2121 Market Street) qualifies, and has qualified during its entire existence, as a partnership, as a disregarded entity, or as an S Corporation for federal income tax purposes, and not as a corporation (other than an S Corporation), an association taxable as a corporation, or a publicly traded partnership. No Intermediary Owner or Property Owner (other than Thomas SPE Corp) has elected (or will elect prior to Closing) to be treated as an association taxable as a corporation for federal income tax purposes under Treasury regulations section ###-###-####-3.

(l) Litigation. Except as set forth in the Disclosure Schedule, and except for Actions covered by the policies of insurance described in clause (bb) below, there is no Action, litigation, claim or other proceeding, either judicial or administrative (including, without limitation, any governmental action or proceeding), pending or, to Contributors’ Knowledge, overtly threatened, affecting all or any portion of the Contributors’ Participating Interests, any Property Interests, any Intermediary Owner or Property Owner or the Contributors’ ability to consummate the transactions contemplated hereby, or which (a) in any manner raises any question affecting the validity or enforceability of this Agreement or seeks restraint, prohibition, damages or other relief in connection with this Agreement or any other material agreement or instrument to which the Intermediary Owners or Property Owners are a party or by which they are bound and that is or is to be used in connection with, or is contemplated by, this Agreement, (b) could reasonably be expected to have a Material Adverse Effect on the business, financial position or results of operations of the Intermediary Owners, Property Owners, Participating Properties, the Operating Partnership or the Company, (c) could reasonably be expected to create a Lien on any Participating Property, or any part thereof or any interest therein, or (d) could reasonably be expected to otherwise materially adversely affect any Participating Property, or any part thereof or any interest therein or the use, operation, condition or occupancy thereof. No outstanding order, writ, injunction or decree of any court, Governmental Entity or arbitration exists against or affecting all or any portion of its Participating Interests, Property Interests (if any), or any Intermediary Owner or Property Owner which in any such case would impair a Contributor’s ability to enter into and perform all of its obligations under this Agreement or would have a Material Adverse Effect.

(m) NASD Affiliation. Each Contributor represents severally that neither it nor any Affiliate of such Contributor is a member, Affiliate of a member or person associated with a member of the National Association of Securities Dealers, Inc. (“NASD”). Such Contributor further represents severally that neither it nor any of its Affiliates owns any stock or other securities of any NASD member not purchased in the open market, or has made any outstanding subordinated loans to a NASD member. (A company or natural person is presumed to control a member of the NASD and is therefore presumed to constitute an Affiliate of such member if the Company or person is the beneficial owner of 10% or more of the outstanding securities of a member which is a corporation. Additionally, a natural person is presumed to control a member of the NASD and is therefore presumed to constitute an Affiliate of such a member if such person has the power to direct or cause the direction of the management or policies of such member.)

(n) Compliance With Laws. In connection with the operation of the Properties, to the Contributors’ Knowledge, except as set forth in the Disclosure Schedule or in the Prospectus, the Properties have been maintained and on the date hereof are, and as of the Closing Date will be, maintained and substantially comply in all material respects with all applicable laws, ordinances, rules, regulations, codes, orders and statutes (including, without limitation, those currently relating to fire and safety, conservation, parking, Americans with Disabilities Act, zoning and building laws) whether federal, state or local, foreign, statutory or common, and neither the Contributors nor, to the Contributors’ Knowledge, any third party have been informed in writing of any material violation of any such laws, rules or regulations, or that any investigation has been commenced or is contemplated respecting any such possible violation. Compliance with Environmental Laws is not addressed by this clause (n), but rather solely by clause (r).

Operating Partnership			Contributors

5.4 Intermediary Organizational Agreements; Consents and Waivers.

(1) As of the Closing, each Contributor waives and relinquishes all rights and benefits otherwise afforded to such Contributor under any Intermediary Owner Agreement (except to the extent such Contributor retains the Excluded Assets in connection with One Commerce Square and Two Commerce Square) including, without limitation, any rights of appraisal, rights of first offer or first refusal, buy/sell agreements, and any right to consent to or approve of the sale or contribution by the other partners or members of each Intermediary Owner of its Participating Interests to the Operating Partnership, the Company or any direct or indirect subsidiary thereof. Each Contributor acknowledges that the agreements contained herein and the transactions contemplated hereby and any actions taken in contemplation of the transactions contemplated hereby may conflict with, and may not have been contemplated by, certain Intermediary Organizational Agreements or other agreements among one or more holders of such Participating Interests or one or more of the partners of any such Intermediary Owner. With respect to each Intermediary Owner and each Participating Property in which a Participating Interest of such Contributor represents a direct or indirect interest, such Contributor expressly gives all Consents (and any consents necessary to authorize the proper parties in interest to give all Consents) and Waivers necessary or desirable to (i) facilitate any Conveyance Action (as hereinafter defined) relating to such Intermediary Owner or Participating Property, (ii) cause the Intermediary Owner to have authority to transfer the Participating Interests or Participating Properties to the Operating Partnership, and (iii) allow the Contributors to receive Partnership Units directly from one or more Intermediary Owners if the Intermediary Owners or one or more of the Intermediary Owner’s subsidiaries transfers assets or interests directly to the Operating Partnership (rather than the Contributor contributing its Participating Interests hereunder) and to reduce the consideration otherwise payable by the Operating Partnership hereunder as a result of such direct transfer by the Intermediary Owner or its subsidiaries on account of Contributors receiving any amount hereunder from such Intermediary Owner or its subsidiaries making such direct transfer; provided that the Operating Partnership shall hold each Contributor harmless (by an agreement in form and substance reasonably acceptable to such Contributor and consistent with the terms of this Section 5.4) for any additional adverse tax consequences to such Contributor or additional costs or liabilities incurred by such Contributor, in each case solely as a result of any Conveyance Action and in excess of those contemplated herein that would have resulted were the transactions consummated pursuant to the contributions contemplated by Sections 1.1 and 1.2. In the event the transactions contemplated by this Agreement do not occur, nothing in this Agreement shall be deemed to or construed as an amendment or modification of, or commitment of any kind to amend or modify, the Intermediary Owner Agreements, which shall remain in full force and effect without modification.

(2) As used herein, the term “Consents” means, with respect to any such Intermediary Owner or Participating Property, any consent necessary or desirable under any Intermediary Owner Agreement or any other agreement among all or any of the holders of

interests therein or any other agreement relating thereto or referred to therein (i) to cause the Intermediary Owner to have authority to permit any and all Conveyance Actions relating to such Intermediary Owner or Participating Property or to amend any such Intermediary Owner Agreement and/or other agreements so that no provision thereof prohibits, restricts, impairs or interferes with any Conveyance Action (such amendments to include, without limitation, the deletion of provisions which cause a default under such agreement if interests therein are transferred for cash), (ii) to admit the Operating Partnership as a substitute limited partner or general partner of such Intermediary Owner upon the Operating Partnership’s acquisition of a limited or general Participating Interest therein, respectively, and to adopt such amendment as is necessary or desirable to effect such admission, (iii) to adopt any amendment to an Intermediary Owner Agreement as may be deemed desirable by the Operating Partnership, either simultaneously with or immediately prior to the acquisition of any interest therein, and (iv) to continue such Intermediary Owner following the transfer of interest therein to the Operating Partnership.

(3) As used herein, the term “Waivers” means, with respect to an Intermediary Owner or a Participating Property of which a Participating Interest of such Contributor represents a direct or indirect interest, the waiving of any and all rights that such Contributor may have with respect to, and (to the extent possible) that any other Person may have with respect to, or that may accrue to such Contributor or other Person upon the occurrence of, a Conveyance Action relating to such Intermediary Owner or Participating Property, including, but not limited to, the following rights: rights of notice, rights to response periods, rights to purchase the direct or indirect interests of another partner in such Intermediary Owner or Participating Property or to sell such Contributor’s or other Person’s direct or indirect interest therein to another partner, rights to sell such Contributor’s or other Person’s direct or indirect interest therein at a price other than as provided herein, or rights to prohibit, limit, invalidate, otherwise restrict or impair any such Conveyance Action or to cause a termination or dissolution of such Intermediary Owner because of such Conveyance Action. Each Contributor further covenants that such Contributor will take no action to enjoin, or seek damages resulting from, any Conveyance Action by any holder of a direct or indirect interest in an Intermediary Owner or a Participating Property in which a Participating Interest of such Contributor represents a direct or indirect interest.

(4) The Waivers and Consents contained in this Section 5.4 shall terminate upon the termination of this Agreement, except as to transactions completed hereunder prior to termination.

6. POWER OF ATTORNEY.

6.1 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 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 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 Participating Interests (including, but not limited to the OP Agreement, as it may be amended or revised, any registration rights agreements and any lock-up agreements), to the acquisition of interests in any entity that directly or indirectly owns a certain Participating Property or Participating Interest by Direct Contribution, Merger or Division, and to provide information to the Securities and Exchange Commission and others about the transactions contemplated hereby, as fully as could such Contributor if personally present and acting (the “Power of Attorney”). Further, each Contributor hereby grants to Attorney-in-Fact a proxy (the “Proxy”) to vote the Participating Interests on any matter related to the Formation Transactions presented to any of the Intermediary Owner’s partners or members for a vote, including, but not limited to, the transfer of interests in any Intermediary Owner by the other partners.

Each of the Power of Attorney and Proxy 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 any 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 and proxy on the same terms set forth in this Article 6, such execution to be witnessed and notarized. Each Contributor hereby authorizes the reliance of third parties on each of the Power of Attorney and Proxy.

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.

The Power of Attorney contained in this Section 6.1 shall expire on the earlier to occur of the fourth anniversary of the Closing or the termination of this Agreement. Notwithstanding anything to the contrary contained herein, the Attorney-in-Fact shall not expand Contributor’s covenants, representations or warranties beyond those contemplated by this Agreement and the other documents and agreements contemplated hereby, and the Attorney-in-Fact shall hold each Contributor harmless to the extent of any such expansion.

6.2 Limitation on Liability.

It is understood that the Attorney-in-Fact (but solely in its role as Attorney-in-Fact) assumes no responsibility or liability to any person by virtue of the Power of Attorney or Proxy granted by the Contributors hereby. Other than as specifically set forth in this Agreement, 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 Participating Interests 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. Each Contributor agrees that the Attorney-in-Fact may consult with counsel of its own choice (who may be counsel for the Operating Partnership or its successors or Affiliates), and it

shall have full and complete authorization and protection for any action taken or suffered by it hereunder in good faith and in accordance with the opinion of such counsel; provided that this provision shall in no way alter or limit any of the obligations of the Operating Partnership (other than in its capacity as Attorney-in-Fact) otherwise set forth in this Agreement. It is understood that the Attorney-in-Fact may, without breaching any express or implied obligation to Contributors hereunder, release, amend or modify any other power of attorney or proxy granted by any other person under any related agreement.

6.3 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 him 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.

7. MISCELLANEOUS.

7.1 Dispute Resolution.

The parties hereby agree that, in order to obtain prompt and expeditious resolution of any disputes under this Agreement, other than as specifically noted, each claim, dispute or controversy of whatever nature, arising out of, in connection with, or in relation to the interpretation, performance or breach of this Agreement (or any other agreement contemplated by or related to this Agreement or any other agreement between the parties), including without limitation any claim based on contract, tort or statute, or the arbitrability of any claim hereunder (provided that “Arbitrable Claims” shall not include any claim, dispute or controversy in connection with Section 7.11, an “Arbitrable Claim”), shall be settled by final and binding arbitration conducted in Los Angeles, California. The arbitrability of any Arbitrable Claims under this Agreement shall be resolved in accordance with the rules and procedures of Judicial Arbitration & Mediation Services, Inc. (“JAMS”). Each Arbitrable Claim shall be resolved pursuant to a two-step dispute resolution process involving, first, mediation before a retired judge from the JAMS panel, followed, if necessary, by final and binding arbitration before the same, or if requested by either party, another JAMS panelist. Such dispute resolution process shall be confidential and shall be conducted in accordance with California Evidence Code Section 1119.

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

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

(c) Costs. The parties shall bear their respective costs incurred in connection with the procedures described in this Section 7.1, except that the parties shall equally share the fees and expenses of the mediator or arbitrator and the costs of the facility for the hearing.

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

7.2 Further Assurances.

Each Contributor shall take such other actions and execute such additional documents following the Closing as the Operating Partnership may reasonably request in order to effect the transactions contemplated hereby, except that no Contributor shall be obligated to take any action or execute any document if the additional actions or documents impose additional liabilities, obligations, covenants, responsibilities, representations or warranties on such Contributor which are not contemplated by this Agreement or reasonably inferable by the terms herein.

7.3 Counterparts.

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

7.4 Governing Law.

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

7.5 Amendment; Waiver.

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

7.6 Entire Agreement.

This Agreement and all related agreements referred to herein constitute the entire agreement and supersede conflicting provisions set forth in all other prior agreements and understandings, both written and oral, among the parties with respect to the subject matter.

7.7 Assignability.

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

7.8 Titles.

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

7.9 Third Party Beneficiary.

No provision of this Agreement is intended, nor shall it be interpreted, to provide or create any third party beneficiary rights or any other rights of any kind in any customer, Affiliate, stockholder, partner, member, director, officer or employee of any party hereto or any other person or entity, other than the Company.

7.10 Severability.

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

7.11 Equitable Remedies.

Each Contributor agrees that irreparable damage would occur to the Operating Partnership in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Operating Partnership shall be entitled to an injunction or injunctions to prevent breaches of this Agreement by a Contributor and to enforce specifically the terms and provisions in any federal or state court located in California (as to which the parties agree to submit to jurisdiction for the purposes of such action), this being in addition to any other remedy to which the

Operating Partnership is entitled under this Agreement or otherwise at law or in equity. Notwithstanding the foregoing, this Agreement shall not bar any equitable remedies otherwise available to a Contributor pursuant to the terms and provisions contained in Exhibit “F”.

7.12 Confidentiality.

All press releases or other public communications of any kind relating to the Public Offering or the transactions contemplated herein, and the method and timing of release for publication thereof, will be subject to the prior written approval of the Operating Partnership.

7.13 Time Of The Essence.

Time is of the essence with respect to all obligations under this Agreement.

7.14 Reliance.

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

7.15 Survival.

It is the express intention and agreement of the parties hereto that the representations, warranties and covenants of each Contributor and Operating Partnership set forth in this Agreement shall survive the consummation of the transactions contemplated hereby; provided, however, that the representations of each Contributor shall survive only for the period specified in Section 3.4. The provisions of this Agreement that contemplate performance after the Closing and the obligations of the parties not fully performed at the Closing shall survive the Closing and shall not be deemed to be merged into or waived by the instruments of Closing.

7.16 Notices.

Any notice to be given hereunder by any party to the other shall be given in writing by (a) personal delivery, or (b) registered or certified mail, postage prepaid, return receipt requested, or (c) nationally reputable overnight courier, and shall be deemed communicated as of the date of delivery if delivered personally, by registered or certified mail, or by overnight courier. Notices shall be addressed as set forth below, provided that any party may change the address set forth below by written notice to other parties in accordance with this Section 7.16.

Partnership in exchange for Partnership Units in the Formation Transactions. Guarantee Partner shall include any successor that assumes or becomes obligated by operation of law or by assumption agreement for the guarantee of debt by the original Guarantee Partner hereunder.

“Partnership Units Sales Restriction” means that, as of the end of the applicable period, aggregate Dispositions by Thomas and each Contributor that is an Affiliate of Thomas of the Partnership Units received by them in the Formation Transactions have not caused the Partnership Units then owned by such Contributors, on an aggregate basis, to be less than fifty percent (50%) of the aggregate number of Partnership Units issued in connection with the Formation Transactions to Thomas and each Contributor that was an Affiliate of Thomas at the time of the Formation Transactions.

Nonrecourse debt of a subsidiary of the Operating Partnership shall be treated as debt of the Operating Partnership provided the Operating Partnership guarantees such debt and will permit the Contributor to indemnify the Operating Partnership from certain losses associated with such guarantee on terms which are similar to those set forth in the Contributor’s Guarantee Agreement and reasonably acceptable to the Operating Partnership and the Contributor;

(ii) In the case of indebtedness that is recourse to all of the assets of the Operating Partnership or a Property Owner, the indebtedness is at all times the most senior indebtedness recourse to all the assets of the Operating Partnership or such Property Owner (but there shall not be a prohibition against other indebtedness that is pari passu with such indebtedness) and the amount of the indebtedness outstanding is at all times at least equal to one hundred fifty percent (150%) of the aggregate amount of the guarantees provided with respect to such indebtedness; or

(iii) Any other indebtedness approved by Thomas (or his designee or legal representative) in each such Person’s sole and absolute discretion.

In addition, debt which satisfies requirement (i) or (ii) above (but not requirement (iii) above) will not be Qualifying Debt if and when either of the following occurs:

(i) There are other guarantees with respect to the same indebtedness that are prior to (i.e., with less economic risk) the Guarantee Opportunity provided to the Contributor pursuant hereto; or

(ii) There are other guarantees with respect to the same indebtedness that are pari passu with the Guarantee Opportunity provided to the Contributor pursuant hereto, and the amount of all such guarantees (including the Contributor’s guarantee) exceed seventy-five percent (75%) of the fair market value of the real estate which is security for such indebtedness measured at the time any such guarantee is first effective (as determined by the Board of Directors of the Company in its reasonable judgment).

Notwithstanding the foregoing, there shall be no prohibition on guarantees of other portions of Qualifying Debt, and the above limitations shall not apply with respect to any guarantee of such debt by the Company, provided the Contributor is offered the opportunity to enter into an agreement with the Company providing that the Contributor will indemnify the Company from certain losses associated with such debt on terms which are similar to those set forth in the Contributor’s Guarantee Agreement with respect to the debt of the Operating Partnership or one or more Property Owners.

ARTICLE 2

SALE RESTRICTION ON PROTECTED PROPERTY

(a) The Operating Partnership agrees for the benefit of Thomas, for the term of the Protected Period, not to directly or indirectly sell, exchange, or otherwise dispose of any of the Participating Properties or in any Entity listed under the definition of Protected Period (or in any Intermediary Owner holding an interest in any such Entity), or any direct or indirect interest therein (including without limitation, by way of merger, sale of assets or otherwise) without the consent of Thomas (or his designee or legal representative) and each Contributor, which consent may be given or withheld in each such Person’s sole and absolute discretion.

(b) Section 2(a) shall not apply to the disposition of any such Participating Property if:

(i) such disposition qualifies as a like-kind exchange under Section 1031 of the Code, or an involuntary conversion under Section 1033 of the Code, or other transaction (including, but not limited to, a contribution of property to any entity that qualifies for the non-recognition of gain under Section 721 or Section 351 of the Code, or a merger or consolidation of the Operating Partnership with or into another entity that qualifies for taxation as a “partnership” for federal income tax purposes (a “Successor Partnership”)), in each case that does not result in the recognition of any taxable income or gain to the Contributor with respect to the Contributor’s Partnership Units; provided, however, that:

(1) in the event of a disposition of a Participating Property under Section 1031 or Section 1033 of the Code or pursuant to another tax deferred transaction, any property that is acquired in exchange for or as a replacement for such Participating Property shall thereafter be considered that Participating Property for purposes of this Exhibit “F”;

(2) if a Participating Property is transferred to another entity in a transaction in which gain or loss is not recognized, the interest of the Operating Partnership in such entity shall thereafter be considered that Participating Property for purposes of this Exhibit “F”, and if the acquiring entity’s disposition of such Participating Property would cause a Contributor to recognize gain or loss as a result thereof, the transferred Participating Property still shall be considered that Participating Property for purposes of this Exhibit “F”; and

(3) in the event of a merger or consolidation involving the Operating Partnership and a Successor Partnership, the Successor Partnership shall have agreed in writing for the benefit of each Contributor that all of the restrictions of this Exhibit “F” shall apply with respect to each Participating Property; or

(ii) with respect to each Contributor, a basis adjustment has occurred to adjust the adjusted taxable basis of the Participating Property in the hands of the Operating Partnership to fair market value as a result of a transaction triggering a basis adjustment such that a taxable disposition of such Participating Property by the Operating Partnership and the allocation of taxable gain to the Contributor pursuant to Section 704(c) of the Code would be completely offset by the basis adjustment.

(c) Notwithstanding any other provision of this Exhibit “F”, the rights and remedies of Thomas for a breach or violation of the covenants set forth in Section 2(a) shall include a claim for damages incurred by him (including, without limitation, incidental, consequential, indirect and special damages, lost profits, lost revenues and loss of business, and direct and indirect adverse tax consequences, whether foreseeable or not) against the Operating Partnership or any Successor Partnership. All such damages shall be indemnifiable under Section 3.4 of the Agreement and shall be treated as “Losses” for purposes thereof. Any claim, dispute or controversy arising out of, or in connection with, or in relation to the interpretation, performance or breach of this Exhibit “F” shall be subject to the provisions of Section 7.1 of the Agreement. The Operating Partnership shall have no liability to any other Person besides Thomas under this Article 2.

ARTICLE 3

AVAILABILITY OF GUARANTEES

(a) During the Protected Period, for the benefit of Thomas, the Operating Partnership shall use commercially reasonable efforts to make available to each Contributor the opportunity (a “Guarantee Opportunity”) to make a guarantee of Qualifying Debt of the Operating Partnership or one or more Property Owners pursuant to a Guaranty Agreement in an amount at least equal to the Guarantee Amount for such Contributor; provided that if the Operating Partnership or one or more of the Property Owners, in the sole discretion of the General Partner, has Qualifying Debt after the end of the Protected Period (without any obligation whatsoever on the part of the Operating Partnership or any Property Owner to maintain or have any such Qualifying Debt after the end of the Protected Period), then each Contributor will continue to have the Guaranty Opportunity after the Protected Period to the extent of such Qualifying Debt. Each Contributor may provide its Guarantee Agreement provided such agreement shall not expand such Contributor’s rights hereunder and shall be subject to the reasonable comments and approval of the Operating Partnership. During the Protected Period, if Guaranteed Debt is to be repaid and, immediately after such repayment, the outstanding amount of such Guaranteed Debt would be less than the Guarantee Amount with respect to such Guaranteed Debt, the Operating Partnership shall use commercially reasonable efforts to provide to each Contributor a new Guarantee Opportunity with respect to Qualifying Debt in an amount equal to the Guaranteed Debt being repaid. In the event that the Operating Partnership is required to use commercially reasonable efforts to offer a Guarantee Opportunity pursuant to this Section 3(a), the Operating Partnership will provide each Contributor notice of the type, amount and other relevant attributes

of the Qualifying Debt with respect to which the Guarantee Opportunity is offered at least ten (10) business days, to the extent reasonably practicable, but in no event less than five (5) business days prior to the earlier of the closing of the incurrence of such debt and the scheduled repayment of the existing Guaranteed Debt. In the event that the Operating Partnership or a related party repurchases outstanding Guaranteed Debt, whether or not such debt is retired, the repurchase thereof shall be treated as a repayment of the Guaranteed Debt for purposes of this Article 3.

(b) Each Contributor acknowledges that Guarantee Partners other than such Contributor have the right to guarantee debt of the Operating Partnership on terms which are similar to the terms set forth in this Exhibit “F”. The Operating Partnership shall use commercially reasonable efforts to offer each Guarantee Opportunity to the Guarantee Partners (including each Contributor) on a pro rata basis, based on the proportion of each Guarantee Partner’s Guarantee Amount to the aggregate Guarantee Amounts of all Guarantee Partners, unless the Guarantee Partners agree to accept Guarantee Opportunities on other than a pro rata basis.

(c) The Operating Partnership agrees to file its tax returns and to cause each Entity to file its tax returns taking the position that the Guaranteed Debt is allocable to each Contributor guaranteeing such debt for purposes of Section 752 of the Code, absent a determination to the contrary by the Internal Revenue Service. However, the Operating Partnership makes no representation or warranty to a Contributor that any guarantee entered into pursuant to Section 3(a) shall be respected for federal income tax purposes so as to enable such Contributor to be considered to bear the “economic risk of loss” with respect to the indebtedness thereby guaranteed by such Contributor for purposes of either Section 752 or Section 465 of the Code.

(d) Notwithstanding any provision of this Exhibit “F”, the rights and remedies of Thomas for a breach or violation of the covenants set forth in Section 3(a) shall include a claim for damages incurred by him (including, without limitation, incidental, consequential, indirect and special damages, lost profits, lost revenues, and loss of business, and direct and indirect adverse tax consequences, whether foreseeable or not) against the Operating Partnership or any Successor Partnership. All such damages shall be indemnifiable under Section 3.4 of the Agreement and shall be treated as “Losses” for purposes thereof. Any claim dispute or controversy arising out of, or in connection with, or in relation to the interpretation, performance or breach of this Exhibit “F” shall be subject to the provisions of Section 7.1 of the Agreement. The Operating Partnership shall have no liability to any other Person besides Thomas under this Article 3.

(e) The Operating Partnership shall not be obligated to undertake efforts to maintain any level of indebtedness in excess of the amounts specifically required to meet the obligations set forth above in this Article 3.

ARTICLE 4

CALCULATION OF DAMAGES

The Operating Partnership acknowledges that any breach or violation by it of its obligations under this Exhibit “F” would cause substantial harm to Thomas, and the Operating

Partnership agrees that any calculation of damages payable to Thomas based solely on the time value of money would not adequately compensate Thomas for the harm caused by any breach by the Operating Partnership of its obligations pursuant to Articles 2 or 3 and any calculation of damages payable to Thomas shall be made without regard to the time value of money or the time period remaining in the Protected Period at the time of such breach or violation by the Operating Partnership. In addition, for purposes of determining any damages payable by the Operating Partnership or a Successor Partnership to Thomas pursuant to Articles 2 or 3, the tax effect on Thomas of any breach or violation of this Exhibit “F” by the Operating Partnership shall be considered.

ARTICLE 5

ACKNOWLEDGEMENT OF CONTRIBUTOR

Each Contributor acknowledges that none of the Operating Partnership, Thomas, or his heirs, estate or other successors by operation of law shall have any duty or obligation to such Contributor with respect to any decision made or action taken by any of them under this Exhibit “F”, including, without limitation, consenting to any sale, accepting indebtedness as “Qualifying Debt” or any other matter. Each Contributor further acknowledges that it shall not have any claim against any of the Operating Partnership, Thomas or his successors or assigns for any adverse tax consequences suffered by such Contributor as a result of any action taken by Thomas or any of his heirs, estate or other successors by operation of law under this Exhibit “F”.

5. Registration. At any time and from time to time the Pledgee may cause all or any of the Collateral to be transferred to or registered in its name or the name of its nominee or nominees.

6. Claims; Value of Collateral.

(a) Subject to Section 3.4 of the Contribution Agreement, on or prior to the date which is one year after the Closing (the “Survival Period”), an Indemnified Party may give notice (a “Claim Notice”) to one or more of the Pledgors of any liability or claim incurred by or asserted against the Indemnified Party which is subject to indemnification under Section 3.4 of the Contribution 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, the Indemnified Party shall give a Claim Notice thereof to the Pledgors, including liabilities or claims to be applied against the indemnification baskets established pursuant to Section 3.4 of the Contribution Agreement. The Indemnified Party may at its option demand indemnity 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 Pledgors. The Indemnified Party shall permit the Pledgors, at the Pledgors’ option and expense, to assume the defense of any such claim by counsel selected by the Pledgors 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 Pledgors 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 the Indemnified Party and its Affiliates a release of all liabilities in respect of such claims, or that does not result only in the payment of money damages which is paid in full by the Pledgors. If the Pledgors 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 Pledgors at the Pledgors’ sole cost and expense; provided, however, that the Pledgors will not be obligated to indemnify the Indemnified Parties for any compromise or settlement entered into without the Pledgors’ prior written consent, which consent shall not be unreasonably withheld.

(b) The value of Collateral (the “Value”) shall be determined as follows: (i) with respect to Collateral consisting of the Pledged Units or other Partnership Interests, an amount equal to the initial public offering price of shares of the Company’s common stock multiplied by the number of shares for which such Collateral is potentially exchangeable; and (ii) for all other Collateral, the fair market value of such Collateral as determined by the Independent Directors of the Company.

7. Voting Rights and Certain Payments Prior to Occurrence of Secured Obligations and Other Events.

(a) Until Collateral may be applied to satisfy a Secured Obligation hereunder, each Pledgor shall be entitled to exercise, as it shall think fit, but in a manner in the judgment of the Pledgee not inconsistent with the terms hereof, the voting power with respect to any such Collateral, and for that purpose the Pledgee shall (if such Collateral shall be registered in the name of the Pledgee or its nominee) execute or cause to be executed from time to time, at the expense of such Pledgor, such proxies or other instruments in favor of such Pledgor or its nominee, in such form and for such purposes as shall be reasonably required by such Pledgor and, if such Pledgor is an entity, shall be specified in a written request therefor of its President or a Vice-President, to enable it to exercise such voting power with respect to such Collateral; provided, however, that no vote shall be cast or such other action taken with respect to the Collateral which would (x) impair the Collateral, (y) adversely affect the rights inuring to the Pledgee or the rights and remedies of the Pledgee under this Agreement or the ability of the Pledgee to exercise the same, or (z) otherwise be inconsistent with or result in any violation of any provision of the Contribution Agreement, this Agreement or any other documents ancillary or related thereto.

(b) Until the Independent Directors of the Company reasonably determine that all or part of the Collateral may reasonably be needed to satisfy the outstanding Claims asserted by the Indemnified Parties in one or more Claim Notices, each Pledgor shall be entitled to receive and retain for its own account any and all regular cash distributions (but not distributions in the form of Partnership Interests or other securities, distributions in kind or liquidating distributions) and interest at any time and from time to time paid upon any of such Collateral. Upon a determination that all or any part of the Collateral may reasonably be needed to satisfy such a Claim, the Pledgee, as determined in the sole discretion of the Independent Directors, shall be entitled to receive and retain for its own account or hold in trust for the account of Pledgor until resolution of the Claim, any and all regular cash distributions and interest at any time and from time to time paid upon any of such Collateral.

(c) Notwithstanding anything contained in this Agreement to the contrary, except with the prior consent of the Pledgee, until such time as this Agreement is terminated, no Pledgor shall have the right to exercise any of its redemption rights under [Section 8.6] of the OP Agreement.

8. Extraordinary Payments and Distributions. In case, upon the dissolution or liquidation (in whole or in part) of the Operating Partnership, any sum shall be paid as a liquidating distribution or otherwise upon or with respect to any of the Collateral, such sum shall be paid over to the Pledgee promptly, and in any event within ten days after receipt thereof, to be held by the Pledgee as additional Collateral hereunder. In case any distribution of Partnership Interests shall be made with respect to the Collateral, or Partnership Interests or fractions thereof shall be issued pursuant to any split involving any of the Collateral, or any distribution of capital shall be made on any of the Collateral, or any partnership interests, shares, obligations or other property shall be distributed upon or with respect to the Collateral pursuant to a recapitalization or reclassification of the capital of the Operating Partnership, or pursuant to the dissolution, liquidation (in whole or in part), bankruptcy or reorganization of the Operating Partnership, or

pursuant to the merger or consolidation of the Operating Partnership with or into another entity, the partnership interests, shares, obligations or other property so distributed shall be delivered to the Pledgee promptly, and in any event within ten (10) days after receipt thereof, to be held by the Pledgee as additional Collateral hereunder, and all of the same (other than cash) shall constitute Collateral for all purposes hereof.

9. Pledgors Obligations Not Affected. The obligations of each Pledgor hereunder shall remain in full force and effect and shall not be impaired by:

(a) any bankruptcy, insolvency, reorganization, arrangement, readjustment, composition, liquidation or the like of any other Pledgor;

(b) any amendments to or modifications of any instrument (other than this Agreement) securing any of the Secured Obligations;

(c) the taking or additional security for, or any guaranty of, any of the Secured Obligations or the release or discharge or termination of any security or guaranty for any of the Secured Obligations; or

(d) the lack of enforceability of any of the Secured Obligations against such Pledgor or any other person, whether or not such Pledgor shall have notice or knowledge of any of the foregoing.

10. Voting Rights and Certain Payments After Occurrence of Secured Obligation and Certain Other Events.

(a) Upon the application of the Collateral (or any part thereof) to satisfy a Secured Obligation hereunder in accordance with Section 13, all rights of any Pledgor to exercise or refrain from exercising all voting power with respect to such Collateral and to otherwise exercise all ownership rights arising from such Collateral shall cease, and thereupon the Pledgee shall be entitled to exercise all voting power with respect to such Collateral and otherwise exercise such ownership rights as though the Pledgee were the outright owner of such Collateral. In the event that the Independent Directors of the Company reasonably determine that the outstanding claims asserted by the Indemnified Parties in one or more Claim Notices may equal or exceed the value of the Collateral then available to satisfy such claims, the Pledgor(s) shall no longer be the owner of such Collateral for tax purposes and all rights of any Pledgor to receive and retain the distributions and interest which it would otherwise be authorized to receive and retain pursuant to Section 7 shall cease, and thereupon the Pledgee shall be entitled to receive and retain, as additional Collateral hereunder, any and all distributions and interest at any time and from time to time paid upon any of such Collateral, provided that, concurrent with making such determination, the Pledgee gives notice thereof to the affected Pledgor(s). Upon receipt of any such notice, a Pledgor may submit the matter to arbitration in accordance with the provisions of the Contribution Agreement, and the decision of the arbitrators as to the retention of any such distributions and interest shall be final and binding between the parties and shall be enforceable in any court of competent jurisdiction.

(b) All payments, distributions or other property or assets which are received by any Pledgor contrary to the provisions of Section 10(a) shall be received and held in trust for the benefit of the Pledgee, shall be segregated from other funds of such Pledgor and shall be forthwith paid over to the Pledgee.

11. Application of Cash Collateral. Any cash received and retained by the Pledgee as additional Collateral pursuant to Section 8 may at any time and from time to time be applied (in whole or in part) by the Pledgee, at its option, to the payment of the Secured Obligations to which such Collateral is subject (in such order as the Pledgee shall in its sole discretion determine).

12. Application of Proceeds. Except as otherwise expressly provided herein, any cash received and retained pursuant to Section 8 shall be applied by the Pledgee: first to the payment of the costs and other expenses arising out of such transaction, including reasonable out-of-pocket costs and expenses of the Pledgee and the fees and expenses of its agents and counsel; second to the payment in full of the Secured Obligations; and finally, to the payment to the Pledgor, or his heirs, executives, administrators, successors or assigns or as a court of competent jurisdiction may direct, of any surplus then remaining.

13. Remedies With Respect to the Collateral.

(a) At such time that a claim becomes a Secured Obligation, the Pledgee, without obligation to resort to other security, shall have the right at any time and from time to time apply, to receive and transfer ownership of all or any part of Collateral with a Value equal to the amount of the Secured Obligation to Pledgee and/or its nominee, in one or more parcels at the same or different times, and all right, title and interest, claim and demand therein and right of redemption thereof. Recourse against the Pledgors is limited to the rights of the Pledgors in any such Collateral that is applied to satisfy a Secured Obligation.

(b) No demand, advertisement or notice, all of which are hereby expressly waived, shall be required in connection with any transfer of Collateral to the Pledgee pursuant to this Agreement.

(c) The remedies provided herein in favor of the Pledgee shall not be deemed exclusive, but shall be cumulative, and shall be in addition to all other remedies in favor of the Pledgee existing at law or in equity, subject to the last sentence of subsection (a) above.

14. Care of Collateral. The Pledgee shall have no duty as to the collection or protection of the Collateral or any income thereon or as to the preservation of any rights pertaining thereto, beyond the safe custody of any thereof actually in its possession. With respect to any maturities, calls, conversions, exchanges, redemptions, offers, tenders or similar matters relating to any of the Collateral (herein called “events”), the Pledgee’s duty shall be fully satisfied if (i) the Pledgee exercises reasonable care to ascertain the occurrence and to give reasonable notice to the Pledgors of any events applicable to any Collateral which are registered and held in the name of the Pledgee or its nominee, (ii) the Pledgee gives the Pledgors reasonable notice of the occurrence of any events, of which the Pledgee has received actual knowledge, as to

any securities which are in bearer form or are not registered and held in the name of the Pledgee or its nominee (the Pledgors agreeing to give the Pledgee reasonable notice of the occurrence of any events applicable to any securities in the possession of the Pledgee of which the Pledgors have received knowledge), and (iii)(a) the Pledgee endeavors to take such action with respect to any of the events as the Pledgors may reasonably and specifically request in writing in sufficient time for such action to be evaluated and taken, or (b) if the Pledgee determines that the Pledgors’ requested action might adversely affect the value of the Collateral, the collection of the Secured Obligations, or otherwise prejudice the interests of the Pledgee, the Pledgee gives reasonable notice to the Pledgors that any such requested action will not be taken; provided that if the Pledgors fail to make such timely request after Pledgee’s notice under clause (ii) or to timely modify their request after Pledgee’s notice under clause (iii)(b), the Pledgee shall then take such other action as it deems advisable in the circumstances. Except as hereinabove specifically set forth, the Pledgee shall have no further obligation to ascertain the occurrence of, or to notify the Pledgors with respect to, any events and shall not be deemed to assume any such further obligation as a result of the establishment by the Pledgee of any internal procedures with respect to any securities in its possession. Except for any claims, causes of action or demands arising out of the Pledgee’s failure to perform its agreements set forth in this Section, the Pledgors release the Pledgee from any claims, causes of action and demands at any time arising out of or with respect to this Agreement, the Collateral and/or any actions taken or omitted to be taken by the Pledgee with respect thereto, and the Pledgors hereby agree to hold the Pledgee harmless from and with respect to any and all such claims, causes of action and demands.

15. Power of Attorney. Each Pledgor hereby appoints the Pledgee as such Pledgor’s attorney-in-fact for the purpose of carrying out the provisions of this Agreement and taking any action and executing any instrument which the Pledgee may deem necessary or advisable to accomplish the purposes hereof. Without limiting the generality of the foregoing, the Pledgee shall have the right and power (a) upon application of any Collateral to satisfy a Secured Obligation, to receive, endorse and collect all checks and other orders for the payment of money made payable to a Pledgor representing any interest or other distribution payable in respect of such Collateral or any part thereof and to give full discharge for the same, and (b) to execute endorsements, assignments or other instruments of conveyance or transfer with respect to all or any of the Collateral.

16. Further Assurances. Each Pledgor shall take such other actions and execute such additional documents as the Operating Partnership may reasonably request in order to effect the transactions contemplated hereby, except that no Pledgor shall be obligated to take any action or execute any document if the additional actions or documents impose additional liabilities, obligations, covenants, responsibilities, representations or warranties on such Pledgor which are not contemplated by this Agreement or the Contribution Agreement or reasonably inferable by the terms herein or therein.

17. No Waiver. No failure on the part of the Pledgee to exercise, and no delay on the part of the Pledgee or of any Covered Party in exercising, any of its options, powers, rights or remedies hereunder, or partial or single exercise thereof, shall constitute a waiver thereof or preclude any other or further exercise thereof or the exercise of any other option, power, right or remedy.

18. Security Interest Absolute. All rights of the Pledgee hereunder, grant of a security interest in the Collateral and all obligations of the Pledgors hereunder, shall be absolute and unconditional irrespective of (a) any lack of validity or enforceability of the Representations Agreement, any of the Secured Obligations or any Grantor Agreement or any other agreement or instrument relating thereto or relating to the Transactions, (b) any change in any term of all or any of the Secured Obligations or any other amendment or waiver of, or any consent to any departure from, the Representations Agreement, any Grantor Agreement or any other agreement or instrument or (c) any other circumstance which might otherwise constitute a defense available to, or a discharge of, any Pledgor in respect of the Secured Obligations or in respect of this Agreement.

19. Expenses. Pledgor agrees to pay the Pledgee all reasonable out-of-pocket expenses of the Pledgee (including reasonable expenses for legal services of every kind) of, or incident to the enforcement of, any provisions of this Agreement.

20. Return of Collateral. Upon the termination of the Survival Period, the Pledgors shall be entitled to the return of all of the Collateral and all other cash held as additional Collateral hereunder which have not been used or applied toward the payment of the Secured Obligations, unless claims asserted in one or more Claim Notices pursuant to Section 6(a) remain outstanding, in which case Collateral with a Value equal to the aggregate dollar amount of such claims shall be retained by the Pledgee pursuant to the terms hereof pending resolution of such claims pursuant to Section 6 (such retained Collateral to consist of Collateral delivered by any Pledgor which may be liable for such claims or, if more than one Pledgor may be liable as to any claim, then in proportion to such Pledgors’ potential liability so long as the Pledgee holds sufficient Collateral of each such Pledgor, and otherwise in any proportion). The assignment by the Pledgee to the Pledgors of such Collateral shall be without representation or warranty of any nature whatsoever and wholly without recourse. Notwithstanding the foregoing, the Pledgors’ release of the Pledgee and agreement to hold the Pledgee harmless set forth in the last sentence of Section 14 shall survive any return of Collateral or termination of this Agreement.

21. Notices. All notices and other communications in connection with this Agreement shall be made in writing by hand delivery, registered first-class mail, telex, telecopier, or air courier guaranteeing overnight delivery:
