Unit Majority.

ARTICLE 4. CAPITAL CONTRIBUTIONS.

4.1 CAPITAL CONTRIBUTIONS OF THE PARTNERS.

A. At the time of the execution of this Agreement, the Partners have been credited with the Adjusted Contributions, contemplated by the Division Agreement, as set forth in Appendix II to this Agreement. Each Limited Partner shall own L.P. Units in the amount set forth for such Partner in Appendix II and shall have a Percentage Interest in the Partnership as set forth in Appendix II, which shall be adjusted in Appendix II from time to time by the General Partner to the extent necessary to reflect accurately exchanges, additional Capital Contributions, the issuance of additional Partnership Interests, the exercise of Put Rights with respect to L.P. Units or similar events having an effect on any Partner’s Percentage Interest.

-14-

B. The number of Units held by the General Partner, in its capacity as general partner, shall be deemed to be the General Partner Interest. Except as provided in Sections 4.2, 10.5 and 13.3, the Partners shall have no obligation to make any additional Capital Contributions.

4.2 ADDITIONAL FUNDS; RESTRICTIONS ON COMPANY.

A. The sums of money required to finance the business and affairs of the Partnership shall be derived from the initial Capital Contributions made to the Partnership by the Company as set forth in the Acquisition Agreement and from funds generated from the operation and business of the Partnership including, without limitation, distributions directly or indirectly received by the Partnership from Available Cash provided by the Operating Partnership. In the event additional financing is needed from sources other than as set forth in the preceding sentence for any reason, subject to the provisions of Sections 8.8 and 8.9, the General Partner may, in its discretion, in such amounts and at such times as it solely shall determine to be necessary or appropriate, obtain additional funds for the Operating Partnership which shall be allocated to each of the partnerships included therein, including the Partnership, pro rata in proportion to the ratio of the number of Units then outstanding in each such Partnership to the total number of L.P. Units then outstanding in the Operating Partnership taken as a whole (“Pro Rata Share”). Accordingly, to the extent of such Pro Rata Share of the Partnership and subject to Section 8.9 and any other limitations contained in this Agreement or the Acquisition Agreement, the General Partner may, (i) cause the Partnership to issue additional Partnership Interests and admit additional Limited Partners to the Partnership in accordance with Section 4.3; (ii) make additional Capital Contributions to the Partnership (subject to the provisions of Section 4.2B.); (iii) cause the Partnership to borrow money, enter into loan arrangements, issue debt securities, obtain letters of credit or otherwise borrow money on a secured or unsecured basis; or (iv) make loans to the Partnership (subject to Section 4.2B.). In no event shall the Limited Partners be required to make any additional Capital Contributions or any loan to, or otherwise provide any financial accommodation for the benefit of, the Partnership pursuant to any such permitted action by the General Partner, except insofar as a Limited Partner has exercised its New Equity Financing Right pursuant to Section 8.8.

B. Except as agreed otherwise at the time by vote or written consent of the L.P. Unit Majority: (i) the Company shall lend to the Partnership its Pro Rata Share of the proceeds of or consideration received by the Company from all loans and advances to the Company pursuant to any financial borrowing arrangement on the same financial terms and conditions, including interest rate and repayment schedule, as shall be applicable with respect to or incurred in connection with the issuance of such loans and advances to the Company (which the Partnership may, in turn, lend to any other partnership constituting part of the Operating Partnership); (ii) in the case of Equity Securities senior or junior to the Common Stock as to dividends and distributions on liquidation, which are not convertible into Common Stock as of the issuance date, the Company shall contribute to the Partnership the proceeds of or consideration (including any property or other non-cash assets) received for such Securities and the proceeds of, or consideration received from, any subsequent exercise, exchange or conversion thereof (if applicable), and shall receive from the Partnership, new Partnership Interests in the Partnership in consideration therefor with the same financial terms and conditions, including dividend, dividend priority, liquidation preference, conversion and redemption rights, as are applicable to such Equity Securities; (iii) in the case of Common Stock, or other Equity Securities convertible into Common Stock as of the issuance date, including, without limitation, shares of Common Stock or other Equity Securities issued upon exercise of options issued under the Stock Option Plan or any other Employee Benefit Plan of the Company, the Company shall contribute to the Partnership the proceeds of or consideration (including any property or other non-

-15-

cash assets) received for such Securities and the proceeds of, or consideration received from, any subsequent exercise, exchange or conversion thereof (if applicable), and shall receive from the Partnership a number of additional Units of General Partner Interest in consideration therefor equal to the product of (x) the number of shares of Common Stock or other Equity Securities issued by the Company, multiplied by (y) the Exchange Factor in effect on the date of such contribution; and (iv) in the case of Common Stock or other Equity Securities issued upon the exercise or surrender of rights under a stock option, warrant, or any other right for which the Company does not receive proceeds, and issues less than the number of shares of Common Stock or other Equity Securities subject to such option, warrant or other right to the holder thereof retaining the excess of such shares as payment of the purchase price (a “net exercise”), or where the Company uses the proceeds received pursuant to a Dividend Reinvestment Plan to acquire shares of Common Stock or other Equity Securities to be issued to the shareholder exercising such right, the Company shall receive from the Partnership a number of additional Units of General Partner Interest equal to the actual number of shares of Common Stock or other Equity Securities so issued to the shareholder multiplied by the Exchange Factor.

4.3 ISSUANCE OF ADDITIONAL PARTNERSHIP INTERESTS; ADMISSION OF ADDITIONAL LIMITED PARTNERS. In addition to any Partnership Interests issuable by the Partnership pursuant to Section 4.2, and subject to the provisions of Sections 8.8 and 8.9, the General Partner is authorized to cause the Partnership to issue additional Partnership Interests (or options therefor) in the form of L.P. Units or other Partnership Interests senior or junior to the L.P. Units to any Persons at any time or from time to time, for consideration per Unit of Partnership Interest not less than the Common Stock Price determined at the initial issuance date divided by the Exchange Factor, and on such other terms and conditions, as the General Partner shall establish provided, however, that (i) each partnership included in the Operating Partnership shall effect its Pro Rata Share of such issuance, (ii) such issuance does not cause the Partnership to become, with respect to any Employee Benefit Plan subject to Title I of ERISA or Section 4975 of the Code, a “party in interest” (as defined in Section 3(14) of ERISA) or a “disqualified person” (as defined in Section 4975(e) of the Code); and (iii) such issuance does not cause any portion of the assets of the Partnership to constitute assets of any Employee Benefit Plan subject to Section 2510.3-101 of the regulations of the United States Department of Labor. Subject to the limitations set forth in the preceding sentence, the General Partner may take such steps as it, in its reasonable discretion, deems necessary or appropriate to admit any Person as a Limited Partner of the Partnership, including, without limitation, amending the Certificate, Appendix II or any other provision of this Agreement.

4.4 REPURCHASE OF COMPANY EQUITY SECURITIES. In the event the Company shall elect to purchase from its shareholders shares of Common Stock for the purpose of delivering such shares to satisfy an obligation under any Dividend Reinvestment Plan or Employee Benefit Plan adopted by the Company, or shall repurchase any other Equity Securities of the Company pursuant to any other share repurchase obligation or arrangement undertaken by the Company with any Company shareholder, including preferred stock redemptions, the purchase price paid by the Company for such shares and any other expenses incurred by the Company in connection with such purchase shall be considered expenses of the Partnership and shall be reimbursed to the Company, subject to the condition that: (i) if such shares subsequently are to be sold by the Company, the Company shall pay to the Partnership any proceeds received by the Company for such shares of Common Stock or other Equity Securities (provided that an exchange of shares of Common Stock for L.P. Units pursuant to the Exchange Rights Agreement would not be considered a sale for such purposes); and (ii) if such shares are not re-transferred by the Company within 30 days after the purchase thereof, the General Partner shall cause the Partnership to cancel the number of Units of

-16-

General Partner Interest held by the Company determined by multiplying (x) the quotient obtained by dividing the total amount deemed paid by the Partnership by the Common Stock Price determined as of the repurchase date, by (y) the Exchange Factor in effect on the date of such repurchase.

4.5 NO THIRD PARTY BENEFICIARY. No creditor or other third party having dealings with the Partnership shall have the right to enforce the right or obligation of any Partner to make Capital Contributions or loans or to pursue any other right or remedy hereunder or at law or in equity, it being understood and agreed that the provisions of this Agreement shall be solely for the benefit of, and may be enforced solely by, the parties hereto and their respective successors and assigns.

4.6 NO INTEREST; NO RETURN. No Partner shall be entitled to interest on its Capital Contribution or on such Partner’s Capital Account. Except as provided in Section 8.7 or Article 13 of this Agreement, or by law, no Partner shall have any right to demand or receive the return of its Capital Contribution from the Partnership.

ARTICLE 5. DISTRIBUTIONS.

5.1 REGULAR DISTRIBUTIONS. Except for distributions pursuant to Section 13.2 in connection with the dissolution and liquidation of the Partnership, and subject to the provisions of Sections 5.3, 5.4 and 5.5, the General Partner shall cause the Partnership to distribute, from time to time as determined by the General Partner, but in any event not less frequently than once each Quarter, the Partnership’s Pro Rata Share of all Available Cash, to the Partners, in accordance with each Partner’s respective Percentage Interest; provided, however, that in no event may a Limited Partner receive a distribution of Available Cash with respect to a L.P. Unit, if such Limited Partner is entitled to receive a distribution out of such Available Cash with respect to a share of Common Stock for which such L.P. Unit has been exchanged.

5.2 QUALIFICATION AS A REIT. The General Partner shall be entitled to cause the Partnership to distribute to the General Partner the Partnership’s Pro Rata Share of Available Cash distributed by the Operating Partnership to enable the General Partner to pay shareholder dividends that will (i) satisfy the REIT Requirements for distributions to shareholders, and (ii) avoid any federal income or excise tax liability of the General Partner; provided, however, the General Partner is not bound to comply with this covenant to the extent such distributions would violate applicable Delaware law.

5.3 WITHHOLDING. With respect to any withholding tax or other similar tax liability or obligation to which the Partnership may be subject as a result of any act or status of any Partner or to which the Partnership becomes subject with respect to any Unit, the Partnership shall have the right to withhold amounts of Available Cash distributable to such Partner or with respect to such Units, to the extent of the amount of such withholding tax or other similar tax liability or obligation pursuant to the provisions contained in Section 10.5.

5.4 ADDITIONAL PARTNERSHIP INTERESTS. If the Partnership issues Partnership Interests in accordance with Section 4.2 or 4.3 which are entitled to certain distribution priorities, Section 5.1 shall be amended, as necessary, to reflect the distribution priority of such Partnership Interests and corresponding amendments shall be made to the provisions of Appendix III.

-17-

ARTICLE 7. MANAGEMENT AND OPERATION OF BUSINESS.

7.1 MANAGEMENT.

A. Except as otherwise expressly provided in this Agreement, and subject to the provisions of Section 8.9, all management powers over the business and affairs the Partnership are and shall be exclusively vested in the General Partner, and no Limited Partner shall have any right to participate in or exercise control or management power over the business and affairs of the Partnership. The General Partner may not be removed by the Limited Partners, with or without cause. In addition to the powers now or hereafter granted a general partner of a limited partnership under the Act or which are granted to the General Partner under any other provision of this Agreement, the General Partner shall have full power and authority to make contracts, sign documents, conduct litigation, acquire and convey property, hire employees, consultants and professionals, raise capital, borrow funds, incur liabilities, invest funds, comply with all applicable laws, and do all other things deemed necessary or desirable by the General Partner to conduct the business of the Partnership on behalf of the Partnership; to exercise all powers set forth in Section 3.2, and to effectuate the purposes set forth in Section 3.1, provided that any exercise of the foregoing rights and powers must be consistent with the REIT Requirements.

B. Except as provided in Section 8.9, each of the Limited Partners agrees that the General Partner is authorized to execute, deliver and perform the agreements and transactions on behalf of the Partnership without any further act, approval or vote of the Partners, notwithstanding any other provision of this Agreement to the fullest extent permitted under the Act or other applicable law, rule or regulation. The execution, delivery or performance by the General Partner or the Partnership of any agreement authorized or permitted under this Agreement shall not constitute a breach by the General Partner of any duty that the General Partner may owe the Partnership or the Limited Partners or any other Persons under this Agreement or of any duty stated or implied by law or equity.

C. At all times from and after the date hereof, in accordance with the provisions of the Acquisition Agreement, the General Partner may cause the Partnership to establish and maintain at any and all times working capital accounts and other cash or similar balances in such amount as the General Partner, in its sole and absolute discretion, deems appropriate and reasonable from time to time. Such accounts may include funds of the General Partner and the other partnerships in the Operating Partnership, which the General Partner shall be free to commingle.

D. In exercising its authority under this Agreement, the General Partner shall take into account the tax consequences to any Partner of any action taken by it and shall select the alternative which appears at the time to present the least adverse tax consequences to the Limited

-18-

Partners. By way of example, but not of limitation: If the General Partner decides to refinance (directly or indirectly) any outstanding indebtedness of the Partnership, the General Partner shall use reasonable efforts to structure such refinancing in a manner that minimizes any adverse tax consequences resulting therefrom to the Limited Partners. The General Partner and the Partnership shall not have liability to a Limited Partner under any circumstances as a result of an income tax liability incurred by such Limited Partner as a result of a necessary action (or inaction) by the General Partner taken pursuant to its authority under and in accordance with this Agreement where avoiding the resulting adverse tax consequences to a Limited Partner was not reasonably practicable under the circumstances.

7.2 CERTIFICATE OF LIMITED PARTNERSHIP. The General Partner shall file the amended Certificate with the Secretary of State of Delaware as required by the Act. The General Partner shall use all reasonable efforts to cause to be filed such other certificates or documents as may be reasonable and necessary or appropriate for the formation, continuation, qualification and operation of a limited partnership (or a partnership in which the limited partners have limited liability) in the State of Delaware and any other state, or the District of Columbia, in which the Partnership may elect to do business or own property. To the extent that such action is determined by the General Partner to be reasonable and necessary or appropriate, the General Partner shall file amendments to and restatements of the Certificate and do all of the things to maintain the Partnership as a limited partnership (or a partnership in which the limited partners have limited liability) under the laws of the State of Delaware and each other state, or the District of Columbia, in which the Partnership may elect to do business or own property. Subject to the terms of Section 8.5A(iv) hereof, the General Partner shall not be required, before or after filing, to deliver or mail a copy of the Certificate or any amendment thereto to any Limited Partner.

7.3 REIMBURSEMENT OF THE GENERAL PARTNER AND THE COMPANY.

A. Except as provided in this Section 7.3 and elsewhere in this Agreement (including the provisions of Articles 5 and 6 regarding distributions, payments, and allocations to which it may be entitled), the General Partner shall not be compensated for its services as general partner of the Partnership.

B. The General Partner, shall be reimbursed on a monthly basis, or such other basis as it may determine in its sole and absolute discretion, for all expenses that it incurs relating to the ownership and operation of, or for the benefit of, the Partnership; provided, that the amount of any such reimbursement shall be reduced by any interest earned by the General Partner with respect to bank accounts or other instruments or accounts held by it in its name. Such reimbursement shall be in addition to any reimbursement made as a result of indemnification pursuant to Section 7.6.

7.4 OUTSIDE ACTIVITIES OF THE GENERAL PARTNER. The General Partner shall not directly or indirectly enter into or conduct any business other than in connection with the ownership, acquisition, development and disposition of Partnership Interests and the management of the business of the Partnership, and such activities as are incidental thereto. The General Partner and any Affiliates of the General Partner may acquire Limited Partner Interests and shall be entitled to exercise all rights of a Limited Partner relating to such Limited Partner Interests.

-19-

7.5 CONTRACTS WITH AFFILIATES.

A. The Partnership may lend or contribute funds or other assets to its Subsidiaries or other Persons in which it has an equity investment and such Persons may borrow funds from the Partnership, on terms and conditions established in the sole and absolute discretion of the General Partner. The foregoing authority shall not create any right or benefit in favor of any Subsidiary or any other Person.

B. Except as provided in Section 7.4, the Partnership may Transfer assets to joint ventures, other partnerships, corporations or other business entities in which it is or thereby becomes a participant upon such terms and subject to such conditions consistent with this Agreement and applicable law as the General Partner, in its sole and absolute discretion, believes are advisable.

C. Except as expressly permitted by this Agreement or otherwise contemplated by the Acquisition Agreement, neither the General Partner nor any of its Affiliates shall sell, Transfer or convey any property to, or purchase any property from, the Partnership, directly or indirectly, except pursuant to transactions that are determined by the General Partner in good faith to be fair and reasonable.

D. Except as provided otherwise in Section 8.9, the General Partner, in its sole and absolute discretion and without the approval of the Limited Partners, may propose and adopt, on behalf of the Partnership, Employee Benefit Plans funded by the Partnership for the benefit of employees of the General Partner, the Partnership, Subsidiaries of the Partnership or any Affiliate of any of them in respect of services performed, directly or indirectly, for the benefit of the Partnership, the General Partner, or any Subsidiaries of the Partnership.

E. The General Partner is expressly authorized to enter into, in the name and on behalf of the Partnership, a “right of first opportunity” or “right of first offer” arrangement, non-competition agreements and other conflict avoidance agreements with various Affiliates of the Partnership and the General Partner, on such terms as the General Partner, in its sole and absolute discretion, believes are advisable.

7.6 INDEMNIFICATION.

A. To the fullest extent permitted by Delaware law, the Partnership shall indemnify each Indemnitee from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including, without limitation, reasonable attorneys’ fees and other legal fees and expenses), judgments, fines, settlements, and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, that relate to the operations of the Partnership or the Company as set forth in this Agreement, in which such Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, except to the extent it is finally determined by a court of competent jurisdiction, from which no further appeal may be taken, that such Indemnitee’s action constituted intentional acts or omissions constituting willful misconduct or fraud. Without limitation, the foregoing indemnity shall extend to any liability of any Indemnitee, pursuant to a loan guaranty or otherwise for any indebtedness of the Partnership or any Subsidiary of the Partnership (including, without limitation, any indebtedness which the Partnership or any Subsidiary of the Partnership has assumed or taken subject to), except with respect to Partnership debt that has been assumed or guaranteed by an Indemnitee in its capacity as a Limited Partner. The General Partner is hereby authorized and empowered, on behalf of the Partnership, to

-20-

enter into one or more indemnity agreements consistent with the provisions of this Section 7.6 in favor of any Indemnitee having or potentially having liability for any such indebtedness. Any indemnification pursuant to this Section 7.6 shall be made only out of the assets of the Partnership, and neither the General Partner nor any Limited Partner shall have any obligation to contribute to the capital of the Partnership, or otherwise provide funds, to enable the Partnership to fund its obligations under this Section 7.6.

B. Reasonable expenses incurred by an Indemnitee who is a party to a proceeding shall be paid or reimbursed by the Partnership in advance of the final disposition of the proceeding.

C. The indemnification provided by this Section 7.6 shall be in addition to any other rights to which an Indemnitee or any other Person may be entitled under any agreement, pursuant to any vote of the Partners, under the Company’s Articles of Incorporation, as a matter of law, or otherwise, and shall continue as to an Indemnitee who has ceased to serve in such capacity unless otherwise provided in a written agreement pursuant to which such Indemnities are indemnified.

D. The Partnership may, but shall not be obligated to, purchase and maintain insurance, on behalf of the Indemnities and such other Persons as the General Partner shall determine, against any liability that may be asserted against or expenses that may be incurred by such Person in connection with the Partnership’s activities, regardless of whether the Partnership would have the power to indemnify such Person against such liability under the provisions of this Agreement.

E. For purposes of this Section 7.6, the Partnership shall be deemed to have requested an Indemnitee to serve as fiduciary of an Employee Benefit Plan whenever the performance by such Indemnitee of its duties to the Partnership also imposes duties on, or otherwise involves services by, such Indemnitee to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an Employee Benefit Pan pursuant to applicable law shall constitute fines within the meaning of this Section 7.6; and actions taken or omitted by the Indemnitee with respect to an Employee Benefit Plan in the performance of its duties for a purpose reasonably believed by it to be in the interest of the participant and beneficiaries of the plan shall be deemed to be for a purpose which is not opposed to the best interests of the Partnership.

F. In no event may an Indemnitee subject any of the Limited Partners to personal liability by reason of the indemnification provisions set forth in this Agreement.

G. An Indemnitee shall not be denied indemnification in whole or in part under this Section 7.6 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

H. The provisions of this Section 7.6 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons. Any amendment, modification or repeal of this Section 7.6 or any provision hereof shall be prospective only and shall not in any way affect the Partnership’s liability to any Indemnitee under this Section 7.6, as in effect immediately prior to such amendment, modification, or repeal with respect to claims arising from or relating to matters occurring, in whole

-21-

or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

I. The provisions of this Section 7.6 shall be inapplicable to any investigation, claim, suit, or proceeding, or the portion thereof, which concerns claims for breach of contract between the Partnership and a Person contracting other than in such Person’s capacity as a Partner, or as an officer or director of the General Partner.

J. No provision of this Section 7.6 shall be construed as permitting any contract or transaction which is prohibited by the provisions of Section 9.2(b) of the Acquisition Agreement.

7.7 LIABILITY OF THE GENERAL PARTNER.

A. Notwithstanding anything to the contrary set forth in this Agreement, the General Partner and its officers and directors shall not be liable for monetary damages to the Partnership, any Partners or any Assignees for losses sustained or liabilities incurred as a result of errors in judgment or of any act or omission, if the General Partner acted in good faith; provided, however, the foregoing shall not be deemed to exculpate the Company from any liability the Company may have under the Acquisition Agreement.

B. Subject to its obligations and duties as General Partner set forth in Section 7.1A hereof, the General Partner may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agent. The General Partner shall not be liable for any acts or omissions on the part of any such agent, except in circumstances for which the General Partner may be liable under Section 7.7A or would not be subject to indemnification under Section 7.6.

C. Any amendment, modification or repeal of this Section 7.7 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the General Partner’s and its officers’ and directors’ liability to the Partnership and the Limited Partners under this Section 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

7.8 LIMITED PARTNERS’ RIGHT TO BRING DERIVATIVE LAWSUITS. Any Limited Partner may bring an action on behalf of the Partnership, as permitted under the Act and the laws of the State of Delaware, to recover a judgment in favor of the Partnership if the General Partner has refused to bring the action or if an effort to cause the General Partner to bring the action is not likely to succeed.

7.9 OTHER MATTERS CONCERNING THE GENERAL PARTNER.

A. The General Partner may rely and shall be protected in acting, or refraining from acting, upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties.

B. The General Partner may consult with legal counsel, accountants, appraisers, management consultants, investment bankers, architects, engineers, environmental consultants and

-22-

other consultants and advisers selected by it, and any act taken or omitted to be taken in reliance upon the opinion of such Persons as to matters which such General Partner reasonably believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion.

C. The General Partner shall have the right, in respect of any of its powers or obligations hereunder, to act through any of its duly authorized officers and duly appointed attorneys-in-fact. Each such attorney shall, to the extent provided by the General Partner in the power of attorney, have full power and authority to do and perform all and every act and duty which is permitted or required to be done by the General Partner hereunder.

D. Notwithstanding any other provisions of this Agreement or the Act, any action of the General Partner on behalf of the Partnership or any decision of the General Partner to refrain from acting on behalf of the Partnership, undertaken in the good faith belief that such action or omission is necessary or advisable in order (i) to protect the ability of the Company to continue to qualify as a REIT; or (ii) to avoid the Company incurring any taxes under Section 857 or Section 4981 of the Code, is expressly authorized under this Agreement and is deemed approved by all of the Limited Partners.

7.10 TITLE TO PARTNERSHIP ASSETS. Title to Partnership assets, whether real, personal or mixed and whether tangible or intangible, shall be deemed to be owned by the Partnership as an entity, and no Partner, individually or collectively, shall have any ownership interest in such Partnership assets or any portion thereof. Title to any or all of the Partnership assets may be held in the name of the Partnership, the General Partner or one or more nominees, as the General Partner may determine, including Affiliates of the General Partner. The General Partner hereby declares and warrants that any Partnership asset for which legal title is held in the name of the General Partner or any nominee or Affiliate of the General Partner shall be held by the General Partner for the use and benefit of the Partnership in accordance with the provisions of this Agreement; provided, that the General Partner shall use its best efforts to cause beneficial and record title to such assets to be vested in the Partnership as soon as reasonably practicable. All Partnership assets shall be recorded as the property of the Partnership in its books and records, irrespective of the name in which legal title to such Partnership assets is held.

Each Limited Partner hereby waives any and all defenses or other remedies which may be available against such Person to contest, negate or disaffirm any action of the General Partner in connection with any such dealing. In no event shall any Person dealing with the General Partner or its representatives be obligated to ascertain that the terms of this Agreement have been complied with or to inquire into the necessity or expedience of any act or action of the General Partner or its representatives. Each and every certificate, document or other instrument executed on behalf of the Partnership by the General Partner or its representatives shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that: (i) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect; (ii) the Person executing and delivering such certificate,

-23-

document or instrument was duly authorized and empowered to do so for and on behalf of the Partnership; and (iii) such certificate, document or instrument was duly executed and delivered in accordance with the terms and provisions of this Agreement and is binding upon the Partnership.

The transaction of any such business by the General Partner, any of its Affiliates or any officer, director, employee, partner, agent or trustee of the General Partner, the Partnership or any of their Affiliates, in their capacity as such, shall not affect, impair or eliminate the limitations on the liability of the Limited Partners or Assignees under this Agreement.

8.5 RIGHTS OF LIMITED PARTNERS RELATING TO THE PARTNERSHIP.

A. In addition to the other rights provided by this Agreement or by the Act, and except as limited by Section 8.5B hereof, each Limited Partner shall have the right, for a purpose reasonably related to such Limited Partner’s interest as a limited partner in the Partnership, upon written demand with a statement of the purpose of such demand and at such Limited Partner’ s own expense (including such reasonable copying and administrative charges as the General Partner may establish from time to time): (i) to obtain a copy of the most recent annual and quarterly reports filed by the Company with the SEC pursuant to the Exchange Act; (ii) to obtain a copy of the Partnership’s federal, state and local income tax returns for each Partnership Year; (iii) to obtain a current list of the name and last known business, residence or mailing address of each Partner; (iv) to obtain a copy of this Agreement and the Certificate and all amendments and/or restatements thereto, together with executed copies of all powers of attorney pursuant to which this Agreement, the Certificate and all amendments and/or restatements thereto have been executed; and (v) to obtain true and full information regarding the amount of cash and a description and statement of any other property or services contributed by each Partner and which each Partner has agreed to contribute in the future, and the date on which each became a Partner.

B. Notwithstanding any other provision of this Section 8.5, the General Partner may keep confidential from the Limited Partners, for such period of time as the General Partner determines in its sole and absolute discretion to be reasonable, any information that (i) the General Partner reasonably believes to be in the nature of trade secrets or other confidential information, the disclosure of which the General Partner in good faith believes is not in the best interests of the Partnership or the Company or could damage the Partnership or its business; or (ii) the Partnership is required by law or by agreements with an unaffiliated third party to keep confidential.

8.6 EXCHANGE RIGHTS. The Limited Partners may exchange all or a portion of their L.P. Units for shares of Common Stock on the terms and subject to the conditions and restrictions contained in the Exchange Rights Agreement.

8.7 PUT RIGHTS.

A. Upon the terms and subject to the conditions of this Agreement, each Limited Partner (other than Xxxx X. Xxxx and Xxxxx X. Xxxx with respect to all L.P. Units owned by them beneficially as of the Effective Date) shall have the right to tender to the Partnership outstanding L.P. Units no more than once during any 12-month period commencing after December 29, 1999. The Partnership shall purchase properly tendered L.P. Units for cash at a price (the “Tender Price”) equal to the average market value of the Common Stock price as of the date the Limited Partner delivers to the General Partner, at the address provided in Appendix II, a completed and duly executed Letter of Transmittal in the form attached as Exhibit A to the Exchange Rights Agreement, and any other documents required by the Letter of Transmittal. Only a tender in this manner will constitute a valid tender of L.P. Units pursuant to this Section 8.7A. The General Partner shall make all determinations as to the validity and form of any tender of L.P. Units in accordance with the provisions of this Agreement, and upon rejection of a tender, shall give the tendering holder written notice of such rejection, which shall include the reasons therefor. Unless otherwise agreed by the General Partner or as provided in Section 8.7C, tenders of L.P. Units pursuant to this Section 8.7A shall be irrevocable and shall not be subject to withdrawal or modification.

-25-

B. Within 15 days after the valid tender of L.P. Units pursuant to Section 8.7A, the Company may make an election to purchase such L.P. Units itself with cash of the Company (the “Cash Election”). If with respect to any tender of L.P. Units pursuant to this Section 8.7, the Company makes the Cash Election, then within 90 days after such tender the Company shall pay to the tendering Limited Partner an aggregate amount of cash equal to the purchase price of the tendered L.P. Units with available cash, borrowed funds or the proceeds of an offering of new shares of Common Stock. Upon acquiring the L.P. Units, the Company may cause the Partnership to retire the L.P. Units and convert them to the same number of Units of General Partner Interest, and the General Partner shall amend Appendix II accordingly.

C. Notwithstanding the foregoing, if the purchase price for the L.P. Units tendered by a Limited Partners in one year exceeds $1,000,000, the Partnership or the Company shall be entitled to reduce proportionally the number of L.P. Units to be acquired from each Tendering Partner so that the total purchase price does not exceed $1,000,000 if the Company so elects. In addition, if the Company does not timely make the Cash Election, the Partnership shall deliver the purchase price for the tendered L.P. Units to the Limited Partner within 45 days after the Letter of Transmittal was delivered to the General Partner. The General Partner may defer payment of the purchase price until such time not to exceed 120 days after the valid tender of L.P. Units pursuant to Section 8.7A as the Partnership has adequate Available Cash after payment of the purchase price, in the reasonable judgment of the General Partner, to fund current distributions necessary for the Company to satisfy the REIT Requirements following the waiver by the Company of its right to make the Cash Election. In such event, the General Partner shall give the tendering Limited Partner written notice of its decision to defer the payment with a calculation supporting the General Partner’s determination within 20 days after the Letter of Transmittal was delivered to the General Partner. Upon receiving such notice, the Limited Partner may withdraw the tender. In addition, the Limited Partner may instead exercise its rights under the Exchange Rights Agreement. If a Limited Partner tenders L.P. Units pursuant to this Section 8.7, the Limited Partner shall pay the amount of any additional documentary, stamp or similar issue or transfer tax which is due, and shall be responsible for all income or other taxes as a result of such exchange.

D. Each tender of L.P. Units shall constitute a representation and warranty by the tendering Limited Partner of each of the representations and warranties set forth in the form of Letter of Transmittal.

E. Until the holder of L.P. Units tendered pursuant to Section 8.7 has received cash in exchange therefor, such Limited Partner shall continue to hold and own such L.P. Units for all purposes of this Agreement.

8.8 NEW EQUITY FINANCING RIGHTS.

A. If the General Partner determines that it is in the best interests of the Partnership to obtain additional funds through the issuance of additional Partnership Interests, the General Partner shall first offer to the Limited Partners in each of the partnerships comprising the Operating Partnership, including the Partnership, the right of first refusal to purchase that portion of such additional Partnership Interests which their respective numbers of L.P. Units bear to the total number of outstanding L.P. Units in the Operating Partnership. The General Partner shall make this offer pursuant to a written notice describing the offering price, class or series of Partnership Interest, and all other material terms of the offer. Such notice shall be sent to each Limited Partner at the address reflected in Appendix II, as amended. The Limited Partners shall have 10 days from the date

-26-

of such notice to elect to purchase any such additional Partnership Interests. Such election shall be made pursuant to a written subscription form specifying the number of Units of additional Limited Partnership Interests the Limited Partner intends to acquire and the total purchase price therefor, and shall be signed by the Limited Partner and delivered to the General Partner at the address set forth on Appendix II. After such 10-day period, the General Partner shall be free to offer any additional Limited Partnership Interests on substantially similar terms to non-Partners and Partners alike.

B. The foregoing right of the Limited Partners to acquire additional equity interests offered by the Partnership (“New Equity Financing Right”) shall not apply to any offering (i) which is part of a transaction in which the Limited Partners had the ability to exercise their New Equity Financing Rights under the Acquisition Agreement with respect to an offering of Equity Securities by the Company, (ii) in connection with a merger or other business combination subject to approval by the L.P. Unit Majority pursuant to Section 8.9, (iii) to a Person in connection with the acquisition of property or services by the Partnership from such Person, or (iv) of any Partnership Interest upon conversion of an outstanding Equity Security of the Partnership, any Partnership Subsidiary, or the Company.

8.9 MATTERS REQUIRING L.P. UNIT MAJORITY APPROVAL.

The consent of the L.P. Unit Majority will be required with respect to the following actions involving the Partnership: (i) the material amendment, modification or termination of the Agreement; (ii) a general assignment for the benefit of creditors or the appointment of a custodian, receiver or trustee for any of the assets of the Partnership; (iii) the institution of any proceeding for bankruptcy of the Partnership; (iv) the Transfer of any General Partnership Interests, including transfers attendant to any merger, consolidation or liquidation of the Company except as otherwise provided in 11.2 C.; (v) the admission of any additional or substitute General Partner in the Partnership; and (vi) a Change of Control Transaction. In addition, until the Protective Provisions Expiration Date, the consent of the L.P. Unit Majority will also be required with respect to: (i) any Terminating Capital Transaction; (ii) the dissolution and liquidation of the Partnership; and (iii) the Partnership’s issuance of Limited Partner Interests having seniority over the L.P. Units with respect to distributing assets, and voting rights.

reporting purposes, on an accrual basis in accordance with GAAP, or such other basis as the General Partner determines to be necessary or appropriate.

10.2 TAX ELECTIONS. The General Partner shall elect for the Partnership to be considered a limited partnership on all applicable federal and state income tax returns to be filed by the Partnership. Except as otherwise provided herein, the General Partner shall, in its sole and absolute discretion, determine whether to make any other available election pursuant to the Code. Notwithstanding the above, in making any such tax election the General Partner shall take into account the tax consequences to the Limited Partners resulting from any such election. The General Partner shall make such tax elections on behalf of the Partnership as the L.P. Unit Majority request, provided that the General Partner believes that such election is not adverse to the interests of the General Partner, including its interest in preserving its qualification as a REIT under the Code. In addition, the General Partner shall elect the “traditional method” of making Section 704(c) allocations pursuant to Regulations Section 1.704-3 with respect to each Property under the Acquisition Agreement. The General Partner shall have the right to seek to revoke any tax election it makes (other than the election to use the traditional method of making the Section 704(c) allocations described in this Section 10.2), including, without limitation, the election under Section 754 of the Code, upon the General Partner’ s determination, in its sole and absolute discretion, that such revocation is in the best interests of the Limited Partners taken as a whole and with the approval of the L.P. Unit Majority until the Protective Provisions Expiration Date. All such elections and determinations may be made on a Property-by-Property basis, and the General Partner shall be required to analyze the impact of all such elections and determinations on that basis.

10.3 TAX MATTERS PARTNER.

A. The General Partner shall be the “tax matters partner” of the Partnership for federal income tax purposes. Pursuant to Section 6230(e) of the Code, upon receipt of notice from the Internal Revenue Service of the beginning of an administrative proceeding with respect to the Partnership, the tax matters partner shall furnish the Internal Revenue Service with the name, address, taxpayer identification number, and Percentage Interest of each of the Limited Partners and the Assignees; provided, that such information is provided to the Partnership by the Limited Partners and the Assignees.

B. The tax matters partner is authorized, but not required:

(1) to enter into any settlement with the Internal Revenue Service with respect to any administrative or judicial proceedings for the adjustment of Partnership items required to be taken into account by a Partner for income tax purposes (such administrative proceedings being referred to as a “tax audit” and such judicial proceedings being referred to as “judicial review”), and in the settlement agreement the tax matters partner may expressly state that such agreement shall bind all Partners, except that such settlement agreement shall not bind any Partner (i) who (within the time prescribed pursuant to the Code and Regulations) files a statement with the Internal Revenue Service providing that the tax matters partner shall not have the authority to enter into a settlement agreement on behalf of such Partner; or (ii) who is a “notice partner” (as defined in Section 6231(a)(8) of the Code) or a member of a “notice group” (as defined in Section 6223(b)(2) of the Code);

-28-

(2) in the event that a notice of a final administrative adjustment at the Partnership level of any item required to be taken into account by a Partner for tax purposes (a “final adjustment”) is mailed to the tax matters partner, to seek judicial review of such final adjustment, including the filing of a petition for readjustment with the Tax Court or the filing of a complaint for refund with the United States Claims Court or the District Court of the United States for the district in which the Partnership’s principal place of business is located;

(3) to intervene in any action brought by any other Partner for judicial review of a final adjustment;

(4) to file a request for an administrative adjustment with the Internal Revenue Service and, if any part of such request is not allowed by the Internal Revenue Service, to file an appropriate pleading (petition or complaint) for judicial review with respect to such request;

(5) to enter into an agreement with the Internal Revenue Service to extend the period for assessing any tax which is attributable to any item required to be taken account of by a Partner for tax purposes, or an item affected by such item; and (6) to take any other action on behalf of the Partners or the Partnership in connection with any tax audit or judicial review proceeding to the extent permitted by applicable law or regulations.

The taking of any action and the incurring of any expense by the tax matters partner in connection with any such proceeding, except to the extent required by law, is a matter in the sole and absolute discretion of the tax matters partner and the provisions relating to indemnification of the General Partner set forth in Section 7.6 of this Agreement shall be fully applicable to the tax matters partner in its capacity as such.

C. The tax matters partner shall receive no compensation for its services. All third party costs and expenses incurred by the tax matters partner in performing its duties as such (including legal and accounting fees and expenses) shall be borne by the Partnership. Nothing herein shall be construed to restrict the Partnership from engaging an accounting firm to assist the tax matters partner in discharging its duties hereunder, so long as the compensation paid by the Partnership for such services is reasonable.

10.4 ORGANIZATIONAL EXPENSES. The Partnership shall elect to deduct expenses, if any, incurred by it in organizing the Partnership ratably over a 60-month period as provided in Section 709 of the Code.

-29-

10.5 WITHHOLDING. Each Limited Partner hereby authorizes the Partnership to withhold from, or pay on behalf of or with respect to, such Limited Partner any amount of federal, state, local, or foreign taxes that the General Partner determines that the Partnership is required to withhold or pay with respect to any amount distributable or allocable to such Limited Partner pursuant to this Agreement, including, without limitation, any taxes required to be withheld or paid by the Partnership pursuant to Sections 1441, 1442, 1445, or 1446 of the Code. Any amount paid on behalf of or with respect to a Limited Partner shall constitute a loan by the Partnership to such Limited Partner, which loan shall be repaid by such Limited Partner within 15 days after notice from the General Partner that such payment must be made unless (i) the Partnership withholds such payment from a distribution which would otherwise be made to the Limited Partner; or (ii) the General Partner determines, in its sole and absolute discretion, that such payment may be satisfied out of the amount of Available Cash which would, but for such payment, be distributed to the Limited Partner. Any amounts withheld pursuant to the foregoing clauses (i) or (ii) shall be treated as having been distributed to such Limited Partner. Each Limited Partner hereby unconditionally and irrevocably grants to the Partnership a security interest in such Limited Partner’ s Partnership Interest to secure such Limited Partner’s obligation to pay to the Partnership any amounts required to be paid pursuant to this Section 10.5. In the event that a Limited Partner fails to pay when due any amounts owed to the Partnership pursuant to this Section 10.5, the General Partner may, in its sole and absolute discretion, elect to make the payment to the Partnership on behalf of such defaulting Limited Partner, and in such event shall be deemed to have loaned such amount to such defaulting Limited Partner and shall succeed to all rights and remedies of the Partnership as against such defaulting Limited Partner. Without limitation, in such event, the General Partner shall have the right to receive distributions that would otherwise be distributable to such defaulting Limited Partner until such time as such loan, together with all interest thereon, has been paid in full, and any such distributions so received by the General Partner shall be treated as having been distributed to the defaulting Limited Partner and immediately paid by the defaulting Limited Partner to the General Partner in repayment of such loan. Any amount payable by a Limited Partner hereunder shall bear interest at the highest base or prime rate of interest published from time to time by any of Xxxxx Fargo Bank, N.A., plus 4 percentage points, but in no event higher than the maximum lawful rate of interest on such obligation, such interest to accrue from the date such amount is due (i.e., 15 days after demand) until such amount is paid in full. Each Limited Partner shall take such actions as the Partnership or the General Partner shall request in order to perfect or enforce the security interest created hereunder.

ARTICLE 11. TRANSFERS AND WITHDRAWALS.

B. In the event the General Partner withdraws as General Partner in accordance with Section 11.2A, the General Partner’s General Partner Interest shall immediately be converted into a Limited Partner Interest.

11.3 LIMITED PARTNERS’ RIGHTS TO TRANSFER.

A. Subject to the provisions of this Section 11.3, a Limited Partner (other than the Company) may, without the consent of the General Partner:

The Incapacity of a Limited Partner, in and of itself, shall not dissolve or terminate the Partnership.

D. No Transfer by a Limited Partner of its L.P. Units may be made to any Person if (i) in the opinion of legal counsel for the Partnership, it would result in the Partnership being treated as an association taxable as a corporation; (ii) such Transfer would cause the Partnership to become, with respect to any Employee Benefit Plan subject to Title I of ERISA, a “party-in-interest” (as defined in Section 3(14) of ERISA) or a “disqualified person” (as defined in Section 4975(c) of the Code); (iii) such Transfer would, in the opinion of legal counsel for the Partnership, cause any portion of the assets of the Partnership to constitute assets of any Employee Benefit Plan pursuant to Department of Labor Regulations Section 2510.2-101; (iv) such Transfer would subject the Partnership to regulation under the Investment Company Act of 1940, the Investment Advisors Act of 1940 or ERISA; or (v) such Transfer is a sale or exchange, and such sale or exchange would, when aggregated with all other sales and exchanges during the 12-month period ending on the date of the proposed Transfer, result in a Change of Control Transaction.

-31-

E. Subject to the foregoing provisions of Section 11.3 and the terms of Section 12.2, a Limited Partner may transfer L.P. Units to an Affiliate and have such Affiliate become a Limited Partner.

In addition to the conditions set forth in Sections 11.3D, 11.4, and 12.2 any Transfer pursuant to this Article 11 is subject to the following conditions:

(2) the transferring Limited Partner and its transferee shall each provide a certificate to the General Partner, in form and substance satisfactory to the General Partner, to the effect that (i) the proposed transfer will not be effected on or through (a) a United States national, regional or local securities exchange, (b) a foreign securities exchange or (c) an interdealer quotation system that regularly disseminates firm buy or sell quotations by identified brokers or dealers (including, without limitation, the Nasdaq) by electronic means or otherwise, and (ii) it is not, and the proposed transfer will not be made by, through or on behalf of, (a) a Person who regularly quotes equity interests in the Partnership, such as a broker or dealer making a market in equity interests in the Partnership or (b) a Person who regularly makes available to the public (including customers or subscribers) bid or offer quotes with respect to equity interests in the Partnership and stands ready to effect buy or sell transactions at the quoted prices for itself or on behalf of others; PROVIDED, HOWEVER, that such certificate shall not be required for any transfer in connection with a registered public offering;

(3) the transferee must be a United States Person for federal income tax purposes; and

(4) such transfer must not cause the Partnership to terminate or lose its status as a partnership for tax purposes.

F. If it shall become unlawful for any Limited Partner to continue to hold some or all of the L.P. Units held by such Limited Partner, or by reason of legal or regulatory restrictions the cost to such Limited Partner to continue to hold such L.P. Units (in relation to the value of such L.P. Units to such Limited Partner) has, in the reasonable judgment of such Limited Partner, significantly increased, such Limited Partner may, at any time following the date three business days after the delivery by such Limited Partner to the General Partner a notice of the existence of any such restriction, Transfer all or any portion of the L.P. Units held by such Limited Partner free of any restrictions imposed under this Agreement (other than those restrictions required by federal or state laws, including securities, and tax, laws, and subject to the prospective transferee meeting the requirements of Section 12.2, and provided that the transferee Limited Partner shall hold its L.P. Units subject to all of the terms of this Agreement); but only if such Limited Partner cannot then

-32-

exercise its Exchange Rights or Put Rights for cash, and the Company has notified the Limited Partner that the Company will not register for offer and sale all shares of Common Stock issued upon the exercise of the Exchange Rights within 90 days. In connection therewith, the Company shall assist such Limited Partner in disposing of the L.P. Units held by it in a prompt and orderly manner, and (at the request of such Limited Partner) make available (and authorize such Limited Partner to make available through the Company) financial and other information concerning the Company and its Subsidiaries (including, without limitation, the information described in Rule 144A(d)(4)) to any prospective purchaser of such L.P. Units (it being agreed that such prospective purchaser shall be either an “accredited investor” within the meaning of Rule 501 (a) under the Securities Act or a “qualified institutional buyer” within the meaning of Rule 144A(d)(1) under such Act to the extent that such L.P. Units are “restricted securities” as such term is defined in Rule 144). The Company may require that each such prospective purchaser keep confidential, pursuant to customary confidentiality requirements, any information received by it pursuant to this provision.

11.4 SUBSTITUTED LIMITED PARTNERS. The General Partner shall have the right to consent to the admission of a transferee who receives L.P. Units pursuant to Section 11.3A, C, or E, which consent may be given or withheld by the General Partner in its sole and absolute discretion. The General Partner’s failure or refusal to permit such transferee to become a Substituted Limited Partner shall not give rise to any cause of action against the Partnership or any Partner.

11.5 ASSIGNEES. If the General Partner, in its sole and absolute discretion, does not consent to the admission of any transferee as a Substituted Limited Partner, as described in Section 11.4, such transferee shall be considered an Assignee for purposes of this Agreement. An Assignee shall be deemed to have had assigned to it, and shall be entitled to receive distributions from the Partnership and the share of Net Income, Net Losses and any other Tax Items with respect to the L.P. Units assigned to such transferee, but shall not be deemed to be a holder of L.P. Units for any other purpose under this Agreement, and shall not be entitled to vote such L.P. Units in any matter presented to the Limited Partners for a vote (such L.P. Units being deemed to have been voted on such matter in the same proportion as all other L.P. Units held by Limited Partners are voted). In the event the Assignee desires to make a further assignment of any such L.P. Units, such Assignee shall be subject to all of the provisions of this Article 11 to the same extent and in the same manner as any Limited Partner desiring to make an assignment of L.P. Units.

11.6 EFFECT OF PROHIBITED TRANSFER. Any transfer made in violation of Article 11 shall be null and void and of no force and effect.

11.7 GENERAL PROVISIONS.

A. No Limited Partner may withdraw from the Partnership other than as a result of a permitted Transfer of all of such Limited Partner’ s L.P. Units in accordance with this Article 11, or pursuant to the tender or exchange of all of its L.P. Units pursuant to the exercise of Put Rights or Exchange Rights.

B. Any Limited Partner who shall Transfer all of its L.P. Units in a Transfer permitted pursuant to this Article 11 shall cease to be a Limited Partner upon the admission of all Assignees of such L.P. Units as Substituted Limited Partners. Similarly, any Limited Partner who shall Transfer all of its L.P. Units pursuant to a tender or exchange of all of its L.P. Units pursuant to the exercise of Put Rights or Exchange Rights shall cease to be a Limited Partner.

-33-

C. Without the consent of the General Partner, permitted Transfers pursuant to this Article 11 may be made effective only as of the first day of a Quarter.

D. If any Partnership Interest is transferred or assigned during the year in compliance with the provisions of this Article 11, or redeemed pursuant to Section 8.7, or exchanged pursuant to the Exchange Rights Agreement on any day other than the first day of a Partnership Year, the Net Income, Net Losses, each item thereof, and all other Tax Items attributable to such interest for such Partnership Year shall be divided and allocated between the transferor Partner and the transferee Partner by taking into account their varying interests during the Partnership Year in accordance with Section 706(d) of the Code, using the interim closing of the books method. Solely for purposes of making such allocations, each of such items for the calendar month in which the Transfer or assignment occurs shall be allocated to the transferee Partner, and none of such items for the calendar month in which an exchange occurs shall be allocated to the exchanging Partner, provided, however, that the General Partner may adopt such other conventions relating to allocations in connection with transfers, assignments, or exchanges as it determines are necessary or appropriate. All distributions of Available Cash attributable to such L.P. Units with respect to which the Partnership Record Date is before the date of such transfer, assignment, or exchange shall be made to the transferor Partner or the exchanging Partner, as the case may be, and in the case of a Transfer or assignment other than an exchange, all distributions of Available Cash thereafter attributable to such L.P. Units shall be made to the transferee Partner.

ARTICLE 12. ADMISSION OF PARTNERS.

12.1 ADMISSION OF SUCCESSOR GENERAL PARTNER. A successor to all of the General Partner Interest pursuant to Article 11 hereof who is proposed to be admitted as a successor General Partner shall be admitted to the Partnership as the General Partner, effective upon the Transfer. Any such transferee shall carry on the business of the Partnership without dissolution. In each case, the admission shall be subject to the successor General Partner executing and delivering to the Partnership an acceptance of all of the terms and conditions of this Agreement, the Acquisition Agreement, and such other documents or instruments as may be required to effect the admission. In the case of such admission on any day other than the first day of a Partnership Year, all items attributable to the General Partner Interest for such Partnership Year shall be allocated between the transferring General Partner and such successor as provided in Section 11.6D.

12.2 ADMISSION OF ADDITIONAL AND SUBSTITUTED LIMITED PARTNERS.

A. A Person who makes a Capital Contribution to the Partnership in accordance with this Agreement after the Effective Date and a Permitted Transferee pursuant to Article 11 shall be admitted to the Partnership as an Additional Limited Partner or a Substituted Limited Partner only upon furnishing to the General Partner (i) evidence of acceptance in form satisfactory to the General Partner of all of the terms and conditions of this Agreement and the Acquisition Agreement, including, without limitation, the power of attorney granted in Section 2.4 hereof and (ii) such other documents or instruments as may be required in the discretion of the General Partner in order to effect such Person’s admission as an Additional Limited Partner.

B. Notwithstanding anything to the contrary in this Section 12.2, no Person shall be admitted as an Additional Limited Partner or a Substituted Limited Partner without the consent of the General Partner, which consent may be given or withheld in the General Partner’s sole and absolute discretion. The admission of any Person as an Additional Limited Partner or a Substituted

-34-

Limited Partner shall become effective on the date upon which the name of such Person is recorded on the books and records of the Partnership, following the consent of the General Partner to such admission.

C. If any Additional Limited Partner is admitted to the Partnership on any day other than the first day of a Partnership Year, then Net Income, Net Losses, each other Tax Item and all other items allocable among Partners and Assignees for such Partnership Year shall be allocated among such Additional Limited Partner and all other Partners and Assignees by taking into account their varying interests during the Partnership Year in accordance with Section 706(d) of the Code, using the interim closing of the books method. Solely for purposes of making such allocations, each of such items for the calendar month in which an admission of any Additional Limited Partner occurs shall be allocated among all of the Partners and Assignees, including such Additional Limited Partner. All distributions of Available Cash with respect to which the Partnership Record Date is before the date of such admission shall be made solely to Partners and Assignees, other than the Additional Limited Partner, and all distributions of Available Cash thereafter shall be made to all of the Partners and Assignees, including such Additional Limited Partner.

D. A transferee who has been admitted as a Substituted Limited Partner or an Additional Limited Partner shall have all the rights and powers and be subject to all the restrictions and liabilities of a Limited Partner under this Agreement.

12.3 AMENDMENT OF AGREEMENT AND CERTIFICATE OF LIMITED PARTNERSHIP. For the admission to the Partnership of any Partner, the General Partner shall take all steps necessary and appropriate under the Act to amend the records of the Partnership and, if necessary, to prepare as soon as practical an amendment of this Agreement (including an amendment of Appendix II) and, if required by law, shall prepare and file an amendment to the Certificate and may for this purpose exercise the power of attorney granted pursuant to Section 2.4 hereof.

ARTICLE 13. DISSOLUTION, LIQUIDATION AND TERMINATION.

13.1 DISSOLUTION. The Partnership shall not be dissolved by the admission of Substituted Limited Partners or Additional Limited Partners or by the admission of a successor General Partner in accordance with the terms of this Agreement. In the event of the withdrawal of the General Partner, any successor General Partner shall continue the business of the Partnership. The Partnership shall dissolve, and its affairs shall be wound up, only upon the first to occur of any of the following (“Liquidating Events”):

(i) the expiration of its term as provided in Section 2.5 hereof;

(ii) an event of withdrawal of the General Partner, as defined in the Act (other than an event of bankruptcy), unless, within 90 days after such event of withdrawal a majority in interest of the remaining Partners agree in writing to continue the business of the Partnership and to the appointment, effective as of the date of withdrawal, of a successor General Partner;

(iii) from and after the date of this Agreement through December 31, 2048, an election to dissolve the Partnership made by the General Partner, with the Consent of Limited Partners holding 66-2/3% or more of the L.P. Units (including L.P. Units held by the Company);

-35-

(iv) on or after January 1, 2049, an election to dissolve the Partnership made by the General Partner, in its sole and absolute discretion;

(v) entry of a decree of judicial dissolution of the Partnership pursuant to the provisions of the Act;

(vi) the sale of all or substantially all of the assets and properties of the Partnership;

(vii) a final and non-appealable judgment is entered by a court of competent jurisdiction ruling that the General Partner is bankrupt or insolvent, or a final and non-appealable order for relief is entered by a court with appropriate jurisdiction against the General Partner, in each case under any federal or state bankruptcy or insolvency laws as now or hereafter in effect, unless prior to the entry of such order or judgment all of the remaining Partners agree in writing to continue the business of the Partnership and to the appointment, effective as of a date prior to the date of such order or judgment, of a substitute General Partner.

13.2 WINDING UP.

A. Upon the occurrence of a Liquidating Event, the Partnership shall continue solely for the purposes of winding up its affairs in an orderly manner, liquidating its assets, and satisfying the claims of its creditors and Partners. No Partner shall take any action that is inconsistent with, or not necessary to or appropriate for, the winding up of the Partnership’s business and affairs. The General Partner, or, in the event there is no remaining General Partner, any Person elected by Limited Partners holding at least a majority of the Limited Partnership Interests (the General Partner or such other Person being referred to herein as the “Liquidator”), shall be responsible for overseeing the winding up and dissolution of the Partnership and shall take full account of the Partnership’s liabilities and property and the Partnership property shall be liquidated as promptly as is consistent with obtaining the fair value thereof, and the proceeds therefrom (which may, to the extent determined by the General Partner, include shares of beneficial interest or other securities of the Company) shall be applied and distributed in the following order:

(i) First, to the payment and discharge of all of the Partnership’s debts and liabilities to creditors other than the Partners;

(ii) Second, to the payment and discharge of all of the Partnership’s debts and liabilities to the General Partner;

(iii) Third, to the payment and discharge of all of the Partnership’s debts and liabilities to the other Partners;

(iv) Fourth, to the General Partner and Limited Partners to the extent of and in accordance with the positive balances in their Capital Accounts, after giving effect to all contributions, distributions, and allocations for all periods; and

(v) The balance, if any, to the Partners according to their Percentage Interests.

-36-

The General Partner shall not receive any additional compensation for any services performed pursuant to this Article 13.

B. Notwithstanding the provisions of Section 13.2A hereof which require liquidation of the assets of the Partnership, but subject to the order of priorities set forth therein, if prior to or upon dissolution of the Partnership the Liquidator determines that an immediate sale of part or all of the Partnership’s assets would be impractical or would cause undue loss to the Partners, the Liquidator may, in its sole and absolute discretion, defer for a reasonable time the liquidation of any asset except those necessary to satisfy liabilities of the Partnership (including to those Partners as creditors) and/or distribute to the Partners, in lieu of cash, as tenants in common and in accordance with the provisions of Section 13.2A hereof, undivided interests in such Partnership assets as the Liquidator deems not suitable for liquidation. Any such distributions in kind shall be made only if, in the good faith judgment of the Liquidator, such distributions in kind are in the best interests of the Partners, and shall be subject to such conditions relating to the disposition and management of such properties as the Liquidator deems reasonable and equitable and to any agreements governing the operation of such properties at such time. The Liquidator shall determine the fair market value of any property distributed in kind using such reasonable method of valuation as it may adopt.

C. In the discretion of the Liquidator, a pro rata portion of the distributions that would otherwise be made to the General Partner and Limited Partners pursuant to this Article 13 may be:

(1) distributed to a trust established for the benefit of the General Partner and Limited Partners for the purposes of liquidating Partnership assets, collecting amounts owed to the Partnership, and paying any contingent or unforeseen liabilities or obligations of the Partnership or the General Partner arising out of or in connection with the Partnership. The assets of any such trust shall be distributed to the General Partner and Limited Partners from time to time, in the reasonable discretion of the Liquidator, in the same proportions as the amount distributed to such trust by the Partnership would otherwise have been distributed to the General Partner and Limited Partners pursuant to this Agreement; or

(2) withheld or escrowed to provide a reasonable reserve for Partnership liabilities (contingent or otherwise) and to reflect the unrealized portion of any installment obligations owed to the Partnership, provided that such withheld or escrowed amounts shall be distributed to the General Partner and Limited Partners in the manner and order of priority set forth in Section 13.2A as soon as practicable.

13.3 OBLIGATION TO CONTRIBUTE DEFICIT. In the event the Partnership is “liquidated” within the meaning Section 1.704-1(b)(2)(ii)(G) of the Regulations, if any Partner’s Adjusted Capital Accounts are less than zero (after giving effect to all contributions, distributions, and allocations for all Fiscal Years, including the Fiscal Year during which such liquidation occurs), such Partner shall contribute to the capital of the Partnership the amount necessary to restore such Partner’s Capital Account to zero in compliance with Regulations Section 1.704-1(b)(2(ii)(B)(3).

13.4 RIGHTS OF LIMITED PARTNERS. Except as otherwise provided in this Agreement, each Limited Partner shall look solely to the assets of the Partnership for the return of its Adjusted Capital Contributions and shall have no right or power to demand or receive property other than cash from the Partnership. Except as otherwise provided in this Agreement, no Limited Partner

-37-

shall have priority over any other Partner as to the return of its Adjusted Capital Contributions, distributions, or allocations.

13.5 NOTICE OF DISSOLUTION. In the event a Liquidating Event occurs or an event occurs that would, but for the provisions of an election or objection by one or more Partners pursuant to Section 13.1, result in a dissolution of the Partnership, the General Partner shall, within 30 days thereafter, provide written notice thereof to each of the Partners.

13.6 TERMINATION OF PARTNERSHIP AND CANCELLATION OF CERTIFICATE OF LIMITED PARTNERSHIP. Upon the completion of the liquidation of the Partnership’s assets, as provided in Section 13.2 hereof, the Partnership shall be terminated, a certificate of cancellation shall be filed, and all qualifications of the Partnership as a foreign limited partnership in jurisdictions other than the state of Delaware shall be canceled and such other actions as may be necessary to terminate the Partnership shall be taken.

13.7 REASONABLE TIME FOR WINDING-UP. A reasonable time shall be allowed for the orderly winding-up of the business and affairs of the Partnership and the liquidation of its assets pursuant to Section 13.2 hereof in order to minimize any losses otherwise attendant upon such winding-up, and the provisions of this Agreement shall remain in effect among the Partners during the period of liquidation.

13.8 WAIVER OF PARTITION. Each Partner hereby waives any right to partition of the Partnership property.

13.9 DEEMED DISTRIBUTION AND RECONTRIBUTION. Notwithstanding any other provisions of this Article 13, in the event the Partnership is liquidated within the meaning of Regulations Section 1.704-1(b)(2)(ii)(G) but no Liquidating Event has occurred, the Property shall not be liquidated, the Partnership’s liabilities shall not be paid or discharged, and the Partnership’s affairs shall not be wound up. Instead, the Partnership shall be deemed to have distributed the Property in kind to the Partners, who shall be deemed to have assumed and taken subject to all Partnership liabilities, all in accordance with their respective Capital Accounts, and if any Partner has an Adjusted Capital Account Deficit (after giving effect to all contributions, distributions, and allocations for all Fiscal Years, including the Fiscal Year during which such liquidation occurs) such Partner shall contribute to the capital of the Partnership the amount necessary to restore such deficit balance to zero in compliance with Regulations Section 1.704-1(b)(2(ii)(B)(3). Immediately thereafter, the Partners shall be deemed to have recontributed the property in kind to the Partnership, which shall be deemed to have assumed and taken subject to all such liabilities.

ARTICLE 14. AMENDMENT OF PARTNERSHIP AGREEMENT; MEETINGS.

14.1 AMENDMENTS.

A. Amendments to this Agreement may be proposed by the General Partner or by any Limited Partners (other than the Company) holding in the aggregate 25% or more of the Partnership Interests. Following such proposal, the General Partner shall submit any proposed amendment to the Limited Partners. The General Partner shall seek the written vote of the Partners on the proposed amendment or shall call a meeting to vote thereon and to transact any other business that it may deem appropriate. For purposes of obtaining a written vote, the General Partner may require a response within a reasonable specified time, but not less than 15 days, and failure to

-38-

respond in such time period shall constitute a vote which is consistent with the General Partner’s recommendation with respect to the proposal. Except as provided in Section 8.9, 13.1C., 14.1B., 14.1C. or 14.1D., a proposed amendment shall be adopted and be effective as an amendment hereto if it is approved by the General Partner and it receives the Consent of Limited Partners holding 50% or more of the Percentage Interests of the Limited Partners (including Limited Partner Interests held by the Company).

B. Notwithstanding any provisions of Sections 8.9 and 14.1A. to the contrary, the General Partner shall have the power, without the consent of the Limited Partners, to amend this Agreement as may be required to facilitate or implement any of the following purposes:

(1) to add to the obligations of the General Partner or surrender any right or power granted to the General Partner or any Affiliate of the General Partner for the benefit of the Limited Partners;

(2) to reflect the admission, substitution, termination, or withdrawal of Partners in accordance with this Agreement;

(3) to set forth the designations, rights, powers, duties, and preferences of the holders of any additional Partnership Interests issued pursuant to Section 4.3 hereof;

(4) to reflect a change that is of an inconsequential nature and does not adversely affect the Limited Partners in any material respect, or to cure any ambiguity, correct or supplement any provision in this Agreement not inconsistent with law or with other provisions, or make other changes with respect to matters arising under this Agreement that will not be inconsistent with law or with the provisions of this Agreement; and

(5) to satisfy any requirements, conditions, or guidelines contained in any order, directive, opinion, ruling or regulation of a federal or state agency or contained in federal or state law.

The General Partner shall provide notice to the Limited Partners when any action under this Section 14.1B is taken.

C. Notwithstanding provision of Section 14.1A. and 14.1B. to the contrary, this Agreement shall not be amended without the Consent of each Partner adversely affected if such amendment would (i) convert a Limited Partner’s interest in the Partnership into a General Partner Interest; (ii) modify the limited liability of a Limited Partner in a manner adverse to such Limited Partner; (iii) alter rights of the Partner to receive distributions pursuant to Article 5 or Article 13, or the allocations specified in Article 6 (except as permitted pursuant to Article IV and Section 14.1B.(3) hereof); (iv) cause the termination of the Partnership prior to the time set forth in Section 2.5 or 13.1; or (v) amend this Section 14.1C. Further, no amendment may alter the restrictions on the General Partner’ s authority set forth in Section 13.1C. without the Consent specified in that section.

-39-

14.2 MEETINGS OF THE PARTNERS.

A. Meetings of the Partners may be called by the General Partner and shall be called upon the receipt by the General Partner of a written request by Limited Partners (other than the Company) holding 25% or more of the Partnership Interests. The request shall state the nature of the business to be transacted. Notice of any such meeting shall be given to all Partners not less than 7 days nor more than 30 days prior to the date of such meeting. Partners may vote in person or by proxy at such meeting. Whenever the vote or Consent of the Limited Partners is permitted or required under this Agreement, such vote or Consent may be given at a meeting of the Partners or may be given in accordance with the procedure prescribed in Section 14.1A. hereof. Except as otherwise expressly provided in this Agreement, the consent of holders of a majority of the Percentage Interests held by Partners (including Limited Partnership Interests held by the Company) shall control.

B. Any action required or permitted to be taken at a meeting of the Partners may be taken without a meeting if a written consent setting forth the action so taken is signed by a majority of the Percentage Interests of the Partners (or such other percentage as is expressly required by this Agreement). Such consent may be in one instrument or in several instruments, and shall have the same force and effect as a vote of a majority of the Percentage Interests of the Partners (or such other percentage as is expressly required by this Agreement). Such consent shall be filed with the General Partner. An action so taken shall be deemed to have been taken at a meeting held on the effective date so certified.

C. Each Limited Partner may authorize any Person or Persons to act for him by proxy on all matters in which a Limited Partner is entitled to participate, including waiving notice of any meeting, or voting or participating at a meeting. Every proxy must be signed by the Limited Partner or his attorney-in-fact. No proxy shall be valid after the expiration of 11 months from the date thereof unless otherwise provided in the proxy. Every proxy shall be revocable at the pleasure of the Limited Partner executing it, such revocation to be effective upon the Partnership’s receipt of written notice of such revocation from the Limited Partner executing such proxy.

D. Each meeting of the Partners shall be conducted by the General Partner or such other Person as the General Partner may appoint pursuant to such rules for the conduct of the meeting as the General Partner or such other Person deems appropriate. Meetings of Partners may be conducted in the same manner as meetings of the shareholders of the Company and may be held at the same time, and as part of, meetings of the shareholders of the Company.

ALLOCATIONS OF PARTNERSHIP INTERESTS

1. ALLOCATION OF NET INCOME AND NET LOSS.

(a) NET INCOME. Except as otherwise provided in this Appendix III, Net Income (or items thereof) (other than Net Income, or items thereof, arising in connection with a Terminating Capital Transaction) for any fiscal year or other applicable period shall be allocated to the Partners in accordance with their respective Percentage Interests.

(b) NET LOSS. Except as otherwise provided in this Appendix III, Net Loss (or items thereof) of the Partnership for each fiscal year or other applicable period shall be allocated to the Partners in accordance with the Partners’ respective Percentage Interests. Notwithstanding the preceding sentence, to the extent any Net Loss (or items thereof) allocated to a Partner under this subparagraph (b) would cause such Partner (hereinafter, a “Restricted Partner”) to have an Adjusted Capital Account Deficit, or increase the amount of an existing Adjusted Capital Account Deficit, as of the end of the fiscal year or other applicable period to which such Net Loss relates, such Net Loss shall not be allocated to such Restricted Partner and instead shall be allocated to the other Partner(s) (hereinafter, the “Permitted Partners”) pro rata in accordance with each Permitted Partner’s Percentage Interest.

(c) TERMINATING CAPITAL TRANSACTION; LIQUIDATION. Allocations of Net Income or Net Loss (or items thereof) in connection with a Terminating Capital Transaction or Liquidation of the Partnership shall first be made so that, to the extent possible, each Partner’s Capital Account balance is equal to such Partner’s Adjusted Contribution, and the remainder of such Net Income or Net Loss (or items thereof) shall be allocated to the Partners in accordance with their Percentage Interests. Notwithstanding the preceding sentence, to the extent any Net Loss (or items thereof) would be allocated to a Restricted Partner under this subparagraph (c), such Net Loss shall not be allocated to such Restricted Partner and instead shall be allocated to the Permitted Partners pro rata in accordance with each Permitted Partner’s Percentage Interest.

(d) RULES OF CONSTRUCTION.

(1) CAPITAL ACCOUNT INCREASES. For purposes of making allocations pursuant to subparagraph 1(c) of this Appendix III, a Partner’s Capital Account balance shall be deemed to be increased by such Partner’s share of any Partnership Minimum Gain and Partner Minimum Gain remaining at the close of the fiscal period in respect of which such allocations are being made.

(2) CHANGE IN PERCENTAGE INTERESTS. In the event any Partner’s Percentage Interest changes during a fiscal year for any reason, including without limitation, the Transfer of any interest in the Partnership, the tax allocations contained in this Appendix III shall be applied as necessary to reflect the varying interests of the Partners during such year.

2. SPECIAL ALLOCATIONS.

Notwithstanding any provisions of paragraph 1 of this Appendix III, the following special allocations shall be made.

(a) MINIMUM GAIN CHARGEBACK (NONRECOURSE LIABILITIES). Except as otherwise provided in Section 1.704-2(f) of the Regulations, if there is a net decrease in Partnership Minimum Gain for any Partnership fiscal year, each Partner shall be specially allocated items of Partnership income and gain for such year (and, if necessary, subsequent years) in an amount equal to such Partner’s share of the net decrease in Partnership Minimum Gain to the extent required by Regulations Section 1.704-2(f). The items to be so allocated shall be determined in accordance with Sections 1.704-2(f) and (j)(2) of the Regulations. This subparagraph 2(a) is intended to comply with the minimum gain chargeback requirement in said section of the Regulations and shall be interpreted consistently therewith. Allocations pursuant to this subparagraph 2(a) shall be made in proportion to the respective amounts required to be allocated to each Partner pursuant hereto.

(b) PARTNER MINIMUM GAIN CHARGEBACK. Except as otherwise provided in Section 1.704-2(i)(4) of the Regulations, if there is a net decrease in Partner Minimum Gain attributable to a Partner Nonrecourse Debt during any fiscal year, each Partner who has a share of the Partner Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Section 1.704- 2(i)(5) of the Regulations, shall be specially allocated items of Partnership income and gain for such year (and, if necessary, subsequent years) in an amount equal to that Partner’s share of the net decrease in the Partner Minimum Gain attributable to such Partner Nonrecourse Debt to the extent and in the manner required by Section 1.704-2(i) of the Regulations. The items to be so allocated shall be determined in accordance with Sections 1.704-2(i)(4) and (j)(2) of the Regulations. This subparagraph 2(b) is intended to comply with the minimum gain chargeback requirement with respect to Partner Nonrecourse Debt contained in said Section 1.704-2(i)(4) of the Regulations and shall be interpreted consistently therewith. Allocations pursuant to this subparagraph 2(b) shall be made in proportion to the respective amounts required to be allocated to each Partner pursuant hereto.

(c) QUALIFIED INCOME OFFSET. In the event a Partner unexpectedly receives any adjustments, allocations or distributions described in Sections 1.704-1(b)(2)(ii)(d)(4), (5) or (6) of the Regulations, and such Partner has an Adjusted Capital Account Deficit, items of Partnership income (including gross income) and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate the Adjusted Capital Account Deficit as quickly as possible as required by the Regulations. This subparagraph 2(c) is intended to constitute a “qualified income offset” under Section 1.704-1(b)(2)(ii)(d) of the Regulations and shall be interpreted consistently therewith.

(d) OTHER CHARGEBACK OF IMPERMISSIBLE NEGATIVE CAPITAL ACCOUNT. To the extent any Partner has an Adjusted Capital Account Deficit at the end of any Partnership Year, each such Partner shall be specially allocated items of Partnership income (including gross income) and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this paragraph 2(d) shall be made if and only to the extent that such Partner would have an Adjusted Capital Account Deficit after all other allocations provided for in this Appendix III have been tentatively made as if this paragraph 2(d) were not in the Agreement.

-2-

(e) NONRECOURSE DEDUCTIONS. Nonrecourse Deductions for any fiscal year or other applicable period shall be allocated to the Partners in accordance with their respective Percentage Interests.

(f) PARTNER NONRECOURSE DEDUCTIONS. Partner Nonrecourse Deductions for any fiscal year or other applicable period with respect to a Partner Nonrecourse Debt shall be specially allocated to the Partner that bears the economic risk of loss for such Partner Nonrecourse Debt (as determined under Sections 1.704-2(b)(4) and 1.704-2(i)(1) of the Regulations).

(g) INTENT OF ALLOCATIONS. The parties intend that the allocation provisions of this Appendix III shall result in final Capital Account balances of the Partners that initially are equal to each Partner’s Adjusted Contribution and are then in proportion to the Partners’ respective Percentage Interests, so that when liquidating distributions are made in accordance with such final Capital Account balances under Section 13.2A(4) hereof, such distributions will be able to return to each Partner its Adjusted Contribution and then will be made in proportion to the Partners’ respective Percentage Interests. To the extent that such final Capital Account balances do not so reflect the provisions of this Appendix III, income and loss of the Partnership for the current year and future years, as computed for book purposes, shall be allocated among the Partners so as to result in final Capital Account balances reflecting the provisions of this Appendix III, and to the extent such allocations of items of income (including gross income) and deduction do not result in such final Capital Account balances, then, income and loss of the Partnership for prior open years, as computed for book purposes (or items of gross income and deduction of the Partnership for such years, as computed for book purposes) shall be reallocated among the Partners consistent with the foregoing. This subparagraph shall control notwithstanding any reallocation of income, loss, or items thereof, as computed for book purposes, by the Internal Revenue Service or any other taxing authority.

(h) SECTION 754 ADJUSTMENT. To the extent an adjustment to the adjusted tax basis of any asset of the Partnership pursuant to Section 734(b) of the Code or Section 743(b) of the Code is required pursuant to Regulations Section 1.704-1(b)(2)(iv)(m) to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be specially allocated among the Partners in a manner consistent with the manner in which each of their respective Capital Accounts are required to be adjusted pursuant to such section of the Regulations.

(i) GROSS INCOME ALLOCATION. There shall be specially allocated to the General Partner an amount of Partnership income and gain during each Partnership Year or portion thereof, before any other allocations are made hereunder, which is equal to the excess, if any, of the cumulative distributions of cash made to the General Partner under Section 7.3B hereof over the cumulative allocations of Partnership income and gain to the General Partner pursuant to this Section (i) of this Appendix III.

3. TAX ALLOCATIONS.

(a) ITEMS OF INCOME OR LOSS. Except as is otherwise provided in this Appendix III, an allocation of Partnership Net Income or Net Loss to a Partner shall be treated as an allocation to such Partner of the same share of each item of income, gain, loss, deduction and item of tax-exempt income or Section 705(a)(2)(B) expenditure (or item treated as such expenditure pursuant to

-3-

Regulations Section 1.704-1(b)(2)(iv)(i)) (“Tax Items”) that is taken into account in computing Net Income or Net Loss.

(b) SECTION 1245/1250 RECAPTURE. If any portion of gain from the sale of Partnership assets is treated as gain which is ordinary income by virtue of the application of Code Sections 1245 or 1250 (“Affected Gain”), then such Affected Gain shall be allocated among the Partners in the same proportion that the depreciation and amortization deductions giving rise to the Affected Gain were allocated. This subparagraph 3(b) shall not alter the amount of Net Income (or items thereof) allocated among the Partners, but merely the character of such Net Income (or items thereof). For purposes hereof, in order to determine the proportionate allocations of depreciation and amortization deductions for each fiscal year or other applicable period, such deductions shall be deemed allocated on the same basis as Net Income and Net Loss for such respective period.

(c) PRECONTRIBUTION GAIN. The Partnership may elect the traditional method of allocation contained in Section 1.704- 3(b) of the Regulations to take into account any variation between the adjusted basis and the fair market value of the Initial Contributed Property at the time of the contribution (“Precontribution Gain”) on a Property-by-Property basis. By executing this Agreement, each Partner hereby agrees to report income, gain, loss and deduction on such Partner’s federal income tax return in a manner that is consistent with the use of the traditional method of allocation with respect to the Initial Contributed Property. With respect to any Contributed Property, the Partnership shall use any permissible method contained in the Regulations promulgated under Section 704(c) of the Code selected by the General Partner, in its sole discretion, to take into account any variation between the adjusted basis of such asset and the fair market value of such asset as of the time of the contribution. Each Partner hereby agrees to report income, gain, loss and deduction on such Partner’s federal income tax return in a manner consistent with the method used by the Partnership.

(d) ALLOCATIONS RESPECTING SECTION 704(C) AND REVALUATIONS. If any asset has a Gross Asset Value which is different from the Partnership’s adjusted basis for such asset for federal income tax purposes because the Partnership has revalued such asset pursuant to Regulations Section 1.704-1(b)(2)(iv)(f), the allocations of Tax Items shall be made in accordance with the principles of Section 704(c) of the Code and the Regulations and the methods of allocation promulgated thereunder, provided, however, that the General Partner shall elect with respect to each Initial Contributed Property, to allocate the income, gain, loss and deduction with respect to such Property using the “traditional method” described in Regulations Section 1.704-3(b) unless the majority of the Limited Partners affected thereby otherwise instruct the General Partner. The intent of this Section 3(d) and Section 3(c) above is that each Partner who contributed to the capital of the Partnership a Contributed Property will bear, through reduced allocations of depreciation, increased allocations of gain or other items, the tax detriments associated with any Precontribution Gain. This Section 3(d) and Section 3(c) are to be interpreted consistently with such intent.

(e) EXCESS NONRECOURSE LIABILITY SAFE HARBOR. Pursuant to Regulations Section 1.752-3(a)(3), solely for purposes of determining each Partner’s proportionate share of the “excess nonrecourse liabilities” of the Partnership (as defined in Regulations Section 1.752-3(a)(3)), the Partners’ respective interests in Partnership profits shall be determined in accordance with each Partner’s Percentage Interest; provided, however, that each Partner who has contributed an asset to the Partnership shall be allocated, to the extent possible, a share of “excess nonrecourse liabilities” of the Partnership which results in such Partner being allocated nonrecourse liabilities in an amount which is at least equal to the amount of income pursuant to Section 704(c) of the Code and the

-4-

Regulations promulgated thereunder (the “Liability Shortfall”). In the event there is an insufficient amount of nonrecourse liabilities to allocate to each Partner an amount of nonrecourse liabilities equal to the Liability Shortfall, then an amount of nonrecourse liabilities in proportion to, and to the extent of, the Liability Shortfall shall be allocated to each Partner.

(f) REFERENCES TO REGULATIONS. Any reference in this Appendix III or the Agreement to a provision of proposed and/or temporary Regulations shall, in the event such provision is modified or renumbered, be deemed to refer to the successor provision as so modified or renumbered, but only to the extent such successor provision applies to the Partnership under the effective date rules applicable to such successor provision.

(g) SUCCESSOR PARTNERS. For purposes of this Appendix III, a transferee of a Partnership Interest shall be deemed to have been allocated the Net Income, Net Loss and other items of Partnership income, gain, loss, deduction and credit allocable to the transferred Partnership Interest that previously have been allocated to the transferor Partner pursuant to this Agreement.

(h) LIMITATION TO PRESERVE REIT STATUS. Notwithstanding anything else in this Agreement, to the extent that the amount paid, credited, distributed or reimbursed by the Partnership or any Partners to, for or with respect any Partner that is a REIT (“REIT Partner”) or its officers, directors, employees or agents, whether as a reimbursement, fee, expense or indemnity (a “REIT Payment”), would constitute gross income to the REIT Partner for purposes of Section 856 (c)(2) or Section 856(c)(3) of the Code, then, notwithstanding any other provision of this Agreement, the amount of such REIT Payments, as selected by the General Partner in its discretion from among items of potential distribution, reimbursement, fees, expenses and indemnities, shall be reduced for any Fiscal Year so that the REIT Payments, as so reduced, to, for or with respect to such REIT Partner shall not exceed the lesser of:

(i) an amount equal to the excess, if any, of (x) four and nine-tenths percent (4.9%) of the REIT Partner total gross income (but excluding the amount of any REIT Payments) for the Fiscal Year that is described in subsections (A) through (H) of Section 856(c)(2) over (y) the amount of gross income (within the meaning of Section 856(c)(2)) derived by the REIT Partner from sources other than those described in subsections (A) through (H) of Section 856(c)(2) (but not including the amount of any REIT Payments); or

(ii) an amount equal to the excess, if any, of (x) 24% of the REIT Partner’s total gross income (but excluding the amount of any REIT Payments) for the Fiscal Year that is described in subsections (A) through (I) of Section 856(c)(3) over (y) the amount of gross income (within the meaning of Section 856(c)(3)) derived by the REIT Partner from sources other than those described in subsections (A) through (I) of Section 856(c)(3) (but not including the amount of any REIT Payments);

PROVIDED, HOWEVER, that REIT payments in excess of the amounts set forth in clauses (i) and (ii) above may be made if the General Partner, as a condition precedent, obtains an opinion of tax counsel that the receipt of such excess amounts shall not adversely affect the REIT Partner’s ability to qualify as a REIT. To the extent that REIT Payments may not be made in a Fiscal Year as a consequence of the limitations set forth in this Section 3(h), such REIT Payments shall carry over and shall be treated as arising in the following Fiscal Year. Nothing in this Section 3(h) shall permit the General Partner to allocate income of the Partnership to any Partner in excess of the income that would otherwise be allocated to it under Article 6 without regard to this Section 3(h). The purpose of

-5-

the limitations contained in this Section 3(h) is to prevent any REIT Partner from failing to qualify as a REIT under the Code by reason of such REIT Partner’s share of items, including distributions, reimbursements, fees, expenses or indemnities, receivable directly or indirectly from the Partnership or the Partners, and this Section 3(h) shall be interpreted and applied to effectuate such purpose.
