For purposes hereof, "Cost Overrun" shall mean any expenditure that shall be required to complete the development of a Building in accordance with the applicable plans and specifications to the extent that such expenditure is not set forth in the approved Operating Budget or exceeds the amount set forth in the Operating Budget.

In the event that the Obligor Partner shall fail to timely make any Shortfall Contribution to the Partnership, the other Partner may, in addition to any other remedies available to the other Partner at law or in equity, make a Capital Contribution to the Partnership in an amount equal to such Shortfall Contribution. In such case, the Obligor Partner shall be treated for all purposes hereunder (including, without limitation, Section 3.2 and Article IX hereof) as a Defaulting Partner with respect to such Shortfall Contribution and the other Partner shall be treated for all purposes hereunder (including, without limitation Section 3.2 and Article IX hereof) as a Non-Defaulting Partner having made a Replacement Loan to the Obligor Partner in the amount of the Shortfall Contribution. Notwithstanding any provision to the contrary set forth herein, any Shortfall Contributions made by an Obligor Partner to the Partnership under this Section 3.1(c) shall not constitute Capital Contributions to the Partnership and shall not affect or result in any adjustment or recalculation of the Unreturned Capital Contributions or Sharing Ratios of the Partners. 3.2 Additional Capital Contributions. (a) In addition to the Original Stratus Contribution and the Olympus Contribution further set forth above and to the extent not available from proceeds of the Construction Loan, (i) the Partners shall make additional Capital Contributions to the Partnership at such times and in such aggregate amounts as shall be approved by the Management Committee, and reflected in an amendment to the Business Plan; (ii) the Partners shall make additional Capital Contributions to the Partnership in accordance with Section 3.5 hereof in the event that the Partnership undertakes the development of the Phase II Property in accordance with Section 3.5 hereof; (iii) if either (A) there has been a default or an event of default under the Construction Loan or (B) additional capital is necessary to complete any capital improvement or development program approved in the Business Plan or reflected in the applicable Operating Budget, then either Partner may elect to call or not call for additional Capital Contributions to be made to the Partnership to cure any default or event of default under the Construction Loan or to complete such capital improvement or development program; or (iv) in the event that Stratus makes any payment to the Construction Lender under that certain Guaranty (a "Guaranty Payment") and the obligation to make such payment shall not be attributable or related to, or arise from any Cost Overrun with respect to which an Obligor Partner shall have an obligation to make a Shortfall Contribution under Section 3.1(c) hereof, or the bad faith, willful misconduct or gross negligence of a Partner or any Affiliate thereof or a material breach by a Partner or any Affiliate thereof of the provisions of the Guaranty, this Agreement or the Management Agreement (collectively, "Operational Defaults"), the Financial Partner shall elect to call for additional Capital Contributions from the Partners in an amount necessary to reimburse Stratus for any portion of the Guaranty Payment which has not already been paid by the Partnership to Stratus. Any Capital Contributions required to be made by the Partners to the Partnership in accordance with this Section 3.2(a) are collectively referred to herein as "Mandatory Additional Contributions." In the event that Stratus shall make a Guaranty Payment, and such Guaranty Payment shall be attributable or relate to, or arise from any Operational Default by a Partner (the "Operational Default Partner") or its Affiliates, then any such Guaranty Payment shall not give rise to any Mandatory Additional Contributions hereunder, rather, in such case the Operational Default Partner shall be obligated to make a cash payment to Stratus in an amount equal to the Guaranty Payment (the "Operational Default Payment") made by Stratus to the Construction Lender, no later than sixty (60) days after written demand therefor delivered by Stratus to the Operational Default Partner. In the event that Stratus shall be the Operational Default Partner, then any such Guaranty Payment shall not result in any Mandatory Additional Contributions or any Operational Default Payments hereunder, rather, Stratus shall have the sole responsibility for any such Guaranty Payment. Any Mandatory Additional Contributions shall be made by the Partners pro rata, based on the Contribution Percentages of the Partners. This Section 3.2(a) is solely for the benefit of the Partners, and shall not, nor shall it be deemed to, create any rights in, or provide any benefit to, any other Person, and the decision to make additional contributions to the Partnership shall be made in the sole and absolute discretion of the Financial Partner, except as may be provided in the Business Plan. (b) Each Partner shall be required to make its Mandatory Additional Contribution to the Partnership on or before twenty-one (21) days after written notice to such Partner ("Default Date"). In the event any Partner fails to make a Mandatory Additional Contribution as required by this Section 3.2 within the time period set forth herein (such Partner, being herein referred to as the "Defaulting Partner"), then, the Partners other than the Defaulting Partner, the "Non-Defaulting Partners" (herein so called) shall be entitled, as their sole and exclusive remedy for such failure, by giving written notice to the Defaulting Partner to make a loan (the "Replacement Loan") to the Defaulting Partner in the amount of such Defaulting Partner's delinquent share of such Mandatory Additional Contribution, which Replacement Loan (i) shall be applied solely to fund the Defaulting Partner's delinquent share of such Mandatory Additional Contribution, (ii) shall have a term of one hundred twenty (120) days from the date of such loan (as such term and maturity date may be accelerated upon any default with respect to the Replacement Loan) and (iii) shall bear interest at the lesser of (A) eighteen percent (18%) per annum and (B) the maximum rate of interest which may be charged, collected or contracted for under applicable law, with accrued interest due at the maturity of such loan (each such Replacement Loan together with all accrued interest thereon from time to time, the "Default Amount"). Anything contained in this Agreement to the contrary notwithstanding, any Partner who becomes a Defaulting Partner shall immediately and without any further demand, notice or cure period (time being of the essence herein) automatically cease to have a right to vote on all Partnership decisions from and after the Default Date for any purposes hereunder for the remainder of the life of the Partnership unless reinstated as described below and any Representatives appointed by such Partner to the Management Committee shall immediately and without any further demand, notice or cure period (time being of the essence herein) automatically cease to have a right to vote on all Management Committee decisions from and after the Default Date for any purposes hereunder for the remainder of the life of the Partnership unless reinstated as described below. If a Defaulting Partner shall pay the Default Amount in full to the Non-Defaulting Partners who elected to make such loan, on or before the expiration of the 120-day term (as the same may be accelerated upon default) of the Replacement Loan to such Defaulting Partner, effective as of the date that such Default Amount is paid in full, such Defaulting Partner's voting rights hereunder and the voting rights of the Representatives appointed by the Defaulting Partner to the Management Committee shall be automatically reinstated. If the Default Amount is not paid in full on or before the expiration of the 120-day period (as the same may be accelerated upon default), the Defaulting Partner's voting rights (and the voting rights of any Representatives appointed by such Defaulting Partner) shall not be reinstated upon the subsequent payment of the Default Amount. (c) The Partners further agree that if the Default Amount is not repaid in full to the Non Defaulting Partners within the 120-day term (as the same may be accelerated upon a default), then, without demand, notice or cure period (time being of the essence herein), such Default Amount shall for all purposes hereunder be deemed to be a Capital Contribution by the Non-Defaulting Partners to the Partnership effective as of the expiration of such 120 day term (as the same may be accelerated upon default) of such Replacement Loan, which deemed Capital Contribution shall, for all purposes hereunder (including, without limitation, the calculation of the Unreturned Capital Contributions, IRR and Sharing Ratio of Olympus hereunder), be credited as an amount equal to the product of 150% multiplied by the Default Amount, and the Sharing Ratio of the Defaulting Partner shall for all purposes be appropriately reduced to reflect such treatment; provided, however, with respect to any Default Amount attributable to a Replacement Loan made more than one hundred twenty (120) days (as the same may be accelerated upon default) after the initial Replacement Loan (which is not repaid during its 120-day term, as the same may be accelerated upon default) made by one or more Non Defaulting Partners, the deemed Capital Contribution shall be credited as an amount equal to the product of 300% multiplied by the Default Amount, and in each case (i.e. with respect to an initial Replacement Loan and/or any subsequent Replacement Loan) the Sharing Ratio of the Defaulting Partner shall be reduced by, and the Sharing Ratio of each Non-Defaulting Partner who makes its pro rata share of such loan shall be increased by an amount equal to the quotient of (i) 150% (or 300%, as the case may be) multiplied by the Default Amount, divided by (ii) the aggregate Capital Contributions made by the Partners to the Partnership (which for purposes of this calculation with respect to Stratus shall not include any amount attributable to the value of the Phase II Property unless and until the Partnership shall commence development of the Phase II Property in accordance with Section 3.5 hereof) prior to the date of calculation (including the Mandatory Additional Contributions of all Non Defaulting Partners, but excluding the Default Amount then in question). (d) In the event that the Sharing Ratio of any Partner shall be adjusted hereunder, the new Sharing Ratios computed in accordance with this Section 3.2 shall remain in effect under this Agreement unless and until there is a subsequent adjustment to the Sharing Ratios. Notwithstanding the foregoing, no Partner's Sharing Ratio shall be reduced under any circumstance to less than zero, nor shall any Partner's Sharing Ratio be increased under any circumstance to more than 100%. Mandatory Additional Contributions shall be made pro rata, based on the relative Contribution Percentages of the Partners (e) Each Partner which becomes an Obligor Partner, an Operational Default Partner, or a Defaulting Partner or Stratus, to the extent of any Indemnification Obligation further described in Section 6.1(c) (in each case, the "Debtor Partner") hereby irrevocably grants to the Partnership and the other Partners a continuing, first priority, perfected security interest in the Partnership Interest of such Debtor Partner to secure the prompt payment of each Shortfall Contribution, Operational Default Payment, Replacement Loan or Indemnification Obligation under Section 6.1(c) hereof (each a "Required Payment") owed by such Defaulting Partner to the Partnership or the other Partners until such time, if ever, as the Required Payment shall have been satisfied (or with respect to a Required Payment arising from a Default Amount, the Replacement Loan under consideration has been converted into a deemed Capital Contribution pursuant to Section 3.2(c), and there shall be no other Required Payments owed by the Debtor Partner to the Partnership or the Partners). On or before fifteen (15) days after any written request of any Partner other than the Debtor Partner (the "Non-Debtor Partners"), the Partner shall execute and deliver a UCC-1 financing statement in form and substance acceptable to such Non-Debtor Partners to evidence such security interest, the failure of which shall constitute a material breach of this Agreement (and a default under any Replacement Loan owed by the Debtor Partner to the Non-Debtor Partners). Upon any default under any Replacement Loan, in addition to any other remedies which may be available to the Non-Defaulting Partners at law or in equity, the maturity date (and one hundred twenty (120) day term) of such Replacement Loan shall be accelerated and all amounts of principal and interest with respect to such Replacement Loan shall immediately become due and payable in-full to the Non-Defaulting Partners. Without limiting the remedies of the Non-Debtor Partners, at law or in equity, at the election of the Non-Debtor Partners, all distributions payable to the Debtor Partner under this Agreement and any fees or other compensation payable by the Partnership to the Debtor Partner or its Affiliates (including without limitation the Fees further described in Sections 6.3 and 6.4 hereof) shall be paid directly to the Partnership and/or the Non-Debtor Partners (pro rata based on the relative amount of the Required Payment owing the Partnership and/or each such Non-Debtor Partner) until the Required Payments are paid in full (or, with respect to any Replacement Loan, converted to a deemed Capital Contribution). Any amounts paid directly to the Partnership and/or the Non-Debtor Partners pursuant to the terms of the preceding sentence shall be treated as paid to the Debtor Partner (or, as applicable, its Affiliate) entitled to receive the amount of the distribution or payment in the absence of the requirements of the preceding sentence (thereby discharging the Partnership's obligation to make the payment in question) and then applied by the Debtor Partner to the repayment of the Debtor Partner's Required Payment. (f) EXCEPT AS SET FORTH IN SECTION 3.1, THIS SECTION 3.2 OR SECTION 3.5 (FOLLOWING THE COMMENCEMENT OF THE DEVELOPMENT OF THE PHASE II PROPERTY, AS DESCRIBED IN SECTION 3.5(E) HEREOF), NO ADDITIONAL CAPITAL CONTRIBUTIONS SHALL BE REQUIRED BY ANY PARTNER UNLESS AN EXPRESS WRITTEN CALL FOR A CAPITAL CONTRIBUTION IS MADE BY THE MANAGEMENT COMMITTEE TO EACH OF THE PARTNERS. 3.3 No Return of Capital Contributions. No Partner is entitled to a return of its Capital Contributions, but shall look solely to distributions from the Partnership as provided for in Article 6 of this Agreement. 3.4 Interest. No Partner shall be entitled to interest on its Capital Contributions or its Capital Account, and any payments to the Partners under Article 6 (whether in the form of IRR payments or otherwise) shall not be deemed to be interest for any purpose. Any interest actually received by reason of temporary investment of any part of the Partnership's funds shall be included in the Partnership's funds. 3.5 Development of Phase II. (a) Upon satisfaction of the Phase II Conditions (as further described herein), the Partnership shall commence development activities on the Phase II Property in accordance with an Operating Budget and Business Plan (and pursuant to plans and specifications with respect to Building II) approved by the Management Committee. For purposes of this Agreement, the "Phase II Conditions" shall be satisfied at such point in time as (i) (A) at least 75% of the gross leasable area of Building I shall be leased by tenants pursuant to leases that have been duly executed by such tenants and the Partnership and approved by the Management Committee, or (B) at least 50% of the projected gross leasable area of Building II shall be leased by tenants pursuant to leases that have been duly executed by such tenants and the Partnership and approved by the Management Committee; and (ii) construction financing shall be available to the Partnership in such amounts and on such terms as further set forth in Schedule III hereof. (b) In the event that the Phase II Conditions have not been satisfied but the Operating Partner determines in good faith that the development of the Phase II Property and the construction of Building II is in the best interests of the Partnership, it shall deliver to the Financial Partner written notice of such proposal (the "Phase II Notice") together with (i) a detailed description of the development activities to be performed on the Phase II Property (including detailed plans and specifications describing Building II) and (ii) a proposed Business Plan and Operating Budget for the development of the Phase II Property and the construction of Building II (collectively, the "Phase II Development Proposal"). In addition, following delivery of the Phase II Notice to the Financial Partner, the Operating Partner shall deliver to the Financial Partner, as soon as reasonably practicable following a request therefor, any and all such information, pro forma and other analyses and other data that the Financial Partner shall request with respect to the proposed development of the Phase II Property and the construction of Building II. On or before the date that is thirty (30) days following receipt of the Phase II Notice, as the same shall be extended to the extent that the Operating Partner shall fail to deliver any requested information to the Financial Partner (such thirty (30) day period, as the same may be extended, being referred to herein as the "Exercise Period"), the Financial Partner may, in its sole discretion, elect to approve the commencement of development activities on the Phase II Property in accordance with the Phase II Development Proposal by delivery of written notice to Stratus (the "Phase II Approval Notice"), in which case, the Partnership shall undertake the development of the Phase II Property and the construction of Building II in accordance with the Phase II Development Proposal. In the event that the Financial Partner shall not deliver a Phase II Approval Notice to Stratus prior to the end of the Exercise Period, the Financial Partner shall be deemed to have rejected the Phase II Development Proposal upon the first Business Day following the expiration of the Exercise Period (the "Rejection Date"), in which case, the Partnership shall not pursue the development of the Phase II Property. Notwithstanding the above provisions of this Section 3.5(b), during the sixty (60) day period following the Rejection Date (the "Phase II Option Exercise Period"), Stratus may elect to purchase the entire interest of Olympus in the Partnership (the "Phase II Purchase Option") for an amount of cash equal to the Unreturned Capital Contributions owing Olympus plus an amount of cash necessary to result in an IRR to Olympus of 25% (the "Purchase Amount"), as calculated through the date of the Phase II Purchase Option Closing (as hereinbelow defined). The Phase II Purchase Option may be exercised by Stratus by its delivery of written notice of such exercise (the "Phase II Purchase Option Exercise Notice") to Olympus during the Phase II Option Exercise Period. In the event that Stratus shall fail to timely deliver a Phase II Purchase Option Exercise Notice to Olympus, such Phase II Purchase Option shall lapse and expire as of the close of business on the final day of the Phase II Option Exercise Period. The closing of the Phase II Purchase Option (the "Phase II Purchase Option Closing") shall take place upon a Business Day chosen by Stratus by delivery of written notice thereof to Olympus which such Business Day shall in no event be later than thirty (30) days following the expiration of the Phase II Option Exercise Period. The sale of Olympus' Partnership Interest to Stratus pursuant to the Phase II Purchase Option shall be made without representation, warranty or recourse, except for representations and warranties in form and substance reasonably acceptable to Olympus and Stratus with respect to existence, good standing, title, no encumbrance, authority, authorization, no conflicts, and such other customary matters as may be reasonably agreed upon by the parties. If the Phase II Purchase Option or the purchase contemplated thereby causes the maturity of any Partnership indebtedness to be accelerated, Olympus shall be released from liability resulting from such accelerated indebtedness and Stratus shall pay (or cause to be paid) such indebtedness in full (including without limitation, any accrued but unpaid interest and any prepayment premiums or penalties) at Stratus' sole cost and expense and shall indemnify and hold Olympus harmless from and against any losses, damages, costs or expenses (including attorneys' fees) incurred by Olympus, or Olympus' Affiliates, employees, agents, representatives, consultants, attorneys, fiduciaries, servants, officers, directors, partners, predecessors, successors and assigns and Affiliates of the foregoing (the "Phase II Indemnified Parties"), as a direct or indirect result of any such acceleration or relating to or otherwise arising from events and occurrences that take place after the Phase II Purchase Option Closing, other than any losses, damages, costs or expenses (including attorneys' fees) incurred by any of the Phase II Indemnified Parties as a direct result of such Phase II Indemnified Parties' gross negligence, willful misconduct or bad faith. As a precondition to the closing of the Phase II Purchase Option, Olympus shall be released from liability from any indebtedness of the Partnership, including, without limitation, the release of any guaranties and/or collateral pledged to secure any guaranteed debt. Anything contained in this Agreement to the contrary notwithstanding, in the event the sale of Olympus' Partnership Interest is not consummated because of a default on the part of Stratus or if a condition precedent cannot be fulfilled, Olympus may, at its election, pursue an action for specific performance and/or damages, costs and expenses. (c) In the event that the Partnership shall undertake the development of the Phase II Property in accordance with Section 3.5(a) or Section 3.5(b) hereof, (i) (A) if the Sharing Ratio of Stratus shall be less than 49.9%, as a condition precedent to the Partnership undertaking the development of the Phase II Property, Stratus shall make a Capital Contribution to the Partnership (the "Stratus Equalization Contribution") in such amount as shall be required to result in the percentage obtained by dividing the aggregate Capital Contributions made (or deemed made) by Stratus to the Partnership (which for purposes hereof shall include, in addition to all other Capital Contributions made by Stratus to the Partnership, the value of the Phase II Property which the Partners agree and acknowledge shall be equal to $1,065,000, notwithstanding that at the time of such determination the fair market value of the Phase II Property may be greater than $1,065,000) by the aggregate Capital Contributions made (or deemed made) by all Partners to the Partnership (which for purposes hereof shall include the value of the Phase II Property which the Partners agree and acknowledge shall be equal to $1,065,000, notwithstanding that at the time of such determination the fair market value of the Phase II Property shall be greater than $1,065,000), to equal 49.9% (the "Stratus Equalization Percentage") and (B) if the Sharing Ratio of Olympus shall be less than 50.1%, as a condition precedent to the Partnership undertaking the development of the Phase II Property, Olympus shall make a Capital Contribution to the Partnership (the "Olympus Equalization Contribution" in such amount as shall be required to result in the percentage obtained by dividing the aggregate Capital Contributions made (or deemed made) by Olympus to the Partnership by the aggregate Capital Contributions made (or deemed made) by all Partners to the Partnership (which for purposes hereof shall include the value of the Phase II Property which the Partners agree and acknowledge shall be equal to $1,065,000, notwithstanding that at the time of such determination the fair market value of the Phase II Property shall be greater than $1,065,000) to equal 50.1% (the "Olympus Equalization Percentage") and (ii) each of Stratus and Olympus shall be required to make Capital Contributions to the Partnership in an amount equal to the Stratus Equalization Percentage and the Olympus Equalization Percentage, respectively multiplied by the amount of any Capital Contributions required in connection with the development of the Phase II Property and/or the construction of Building II by the Partnership, as reflected in the applicable Operating Budget and Business Plan (any such Capital Contributions by a Partner to be made to the Partnership at the same time as any Capital Contributions made by the other Partner, to the Partnership). Immediately following the Equalization Contribution by Stratus or Olympus (as the case may be) to the Partnership, the Sharing Ratio and Contribution Percentage of Olympus shall be adjusted to 50.1% and the Sharing Ratio and Contribution Percentage of Stratus shall be adjusted to 49.9%. (d) From and after the Effective Date hereof and for so long as the Partnership shall hold the Building II Permit for the development and construction of Building II but shall not have commenced the development of the Phase II Property (as further described in Section 3.5(e)), the Partnership shall not undertake any development activities or make any expenditures with respect to the Phase II Property, other than such minimum development activities and expenditures, in an amount not to exceed in the aggregate $300,000 with respect to all periods following the Effective Date, as shall be required to maintain the Building II Permit and as shall be approved in advance and in writing by Olympus (such approval not to be unreasonably withheld or delayed). Stratus hereby represents and warrants to Olympus that, as of the Effective Date, the aggregate expenditures made by Stratus with respect to the construction of Building II and the development of the Phase II Property are as set forth in Schedule IV hereto. (e) For purposes of this Section 3.5 and the further provisions of this Agreement, the Partnership shall be deemed to have commenced the development of the Phase II Property as of the date upon which (i) (A) the Phase II Conditions have been satisfied or (B) Olympus has delivered a Phase II Approval Notice to Stratus, (ii) the Management Committee shall have approved a Business Plan and Operating Budget with respect to the development of the Phase II Property and plans and specifications relating to Building II, (iii) a construction management agreement and any requisite construction contracts shall have been approved by the Management Committee and executed by the Partnership and all other parties thereto, and (iv) the Partnership shall have obtained sufficient construction financing to pursue the development of the Phase II Property and the construction of Building II. ARTICLE 4 Rights and Obligations of Partners 4.1 Management of Partnership. The management, control and direction of the Partnership and its operations, business and affairs shall be vested exclusively in the Management Committee, which shall have the right, power and authority, acting solely by itself and without the necessity of approval by any Partner or any other person, to carry out any and all of the purposes of the Partnership and to perform or refrain from performing any and all acts that the Management Committee may deem necessary, desirable, appropriate or incidental thereto, except as otherwise provided in this Agreement; provided, however, that the Operating Partner shall manage the Partnership and its operations, business and affairs solely as described in Section 4.5. The Management Committee may assume the management duties and responsibilities of the Operating Partner as set forth in Section 4.5 at any time in the event the Management Committee determines in its good faith discretion that (i) the Operating Partner has acted negligently or with willful misconduct in performing its duties, (ii) the monthly financial reports of the Partnership reveal a material adverse deviation from the Business Plan more than three (3) times within any twelve (12) month period, (iii) the Operating Partner has breached a material provision of this Agreement or (iv) a Bankruptcy has occurred with respect to the Operating Partner. The Management Committee agrees that prior to its exercise of its right to assume the management duties and responsibilities of the Operating Partner as a result of a default by the Operating Partner further described in clauses (i) or (iii) of the immediately preceding sentence, the Management Committee shall first deliver written notice of said default to the Operating Partner and give the Operating Partner ten (10) days thereafter in which to cure said default, if the Operating Partner so elects. 4.2 Management Committee. (a) The "Management Committee" (herein so called) shall consist of four (4) representatives, two (2) of which shall be designated by Stratus (collectively, the "Stratus Representatives") and two (2) of which shall be designated by Olympus (collectively, the "Olympus Representatives") (individually, a "Representative and collectively, the "Representatives"). The initial Representatives designated by Stratus and Olympus are set forth opposite such Partner's name below: Partner Initial Representative Stratus J.B. Brown Stratus William H. Armstrong, III Olympus Greg Adair Olympus Hal R. Hall Olympus and Stratus may appoint alternates for the Representatives appointed by it, which alternates shall have all the powers of the Representatives in their absence or inability to serve. Olympus hereby appoints Ron J. Hoyl as an alternate Representative. Stratus hereby appoints John E. Baker as an alternate Representative. Olympus and Stratus may change its designated Representatives effective upon written notice from Olympus or Stratus designating such Representative to the other Partners. Olympus shall designate one of the Olympus Representatives who shall serve as Chairman of the Management Committee and shall set the agenda for such meetings. (b) The Representatives shall meet quarterly (or more often as the Management Committee may reasonably determine) in the offices of the Partnership or by telephone conference, unless the Representatives jointly agree that the meeting is unnecessary or that a different schedule or location for the meeting is appropriate, to discuss current material management issues (but not day-to-day operations matters which are in accordance with the operation parameters set forth in the Business Plan, Operating Budget or otherwise set forth in writing) or Major Decisions. At each meeting the Representatives shall each receive one (1) vote. All action taken by the Management Committee, including any Major Decisions, shall require the approval or consent of at least one Olympus Representative and at least one Stratus Representative; provided, however, that in the event that either of Olympus or Stratus shall be a Defaulting Partner and its designated Representatives shall lose their voting rights in accordance with Section 3.2(b) hereof, then, unless and until such voting rights shall be reinstated under Section 3.2(b) hereof, all action taken by the Management Committee, including any Major Decisions, shall require the approval or consent of the two Representatives appointed by the Non-Defaulting Partner. Representatives may bring to any meeting such employees, agents, professionals and advisors as they deem necessary or appropriate to assist them at such meeting. A quorum shall consist of at least one Stratus Representative and one Olympus Representative unless either of Olympus or Stratus shall be a Defaulting Partner and its designated Representatives shall lose their voting rights in accordance with Section 3.2(b) hereof, in which case, unless and until such voting rights shall be reinstated under Section 3.2(b) hereof, a quorum shall consist of the two Representatives appointed by the Non-Defaulting Partner. (c) The Financial Partner, at the direction of the Management Committee, shall be authorized and empowered to (i) make all day-to-day management decisions (provided that such decisions are consistent with the operation parameters set forth in the Business Plan, Operating Budget or otherwise in writing) except for Major Decisions, (ii) direct the Operating Partner (which shall be obligated to follow any such directives), and (iii) perform all acts and enter into and perform all contracts and other undertakings that the Financial Partner may, in the exercise of its reasonable discretion, deem necessary, advisable, appropriate or incidental thereto; provided that any directives of the Financial Partner under clause (ii) hereof and the performance of any acts under clause (iii) hereof are consistent with the operation parameters set forth in the Business Plan, Operating Budget or otherwise in writing. Notwithstanding any provision of this Agreement to the contrary, the Financial Partner acting singly and without necessity of joinder of any other Person shall be authorized and empowered to exercise any rights and remedies granted to the Partnership under the Management Agreement (including, without limitation, the provision or withholding of consent, the making of any elections and any other decisions of the Partnership thereunder). The authority granted to the Financial Partner hereunder with respect to the Management Agreement shall include, without limitation, the power to terminate the Management Agreement in accordance with its terms. If the Management Agreement is terminated, then the Financial Partner shall have the power and authority to replace Stratus Management as the construction manager and to designate a successor construction manager. In connection therewith, the Financial Partner shall have the power and authority acting alone and without necessity of joinder of any other Person to negotiate, enter into and execute (on behalf of the Partnership) a construction management agreement pursuant to which such successor construction manager shall provide construction management services to the Partnership for the consideration set forth therein. Upon the execution by the Financial Partner of any such construction management agreement, the Operating Budget and Business Plan shall automatically, and without any approval or consent of the Partners or the Representatives, be amended to reflect the terms of the construction management agreement between the Partnership and the successor construction manager. 4.3 Major Decisions. Except as otherwise expressly provided to the contrary in Article 3, Article 4, Article 7 or Article 9 hereof, Major Decisions shall be made upon the prior written approval or written consent of at least one Stratus Representative and at least one Olympus Representative. Accordingly, except as provided to the contrary in Article 3, Article 4, Article 7 or Article 9 hereof, neither Stratus nor Olympus, on behalf of the Management Committee, shall have the right or the power to make any binding commitment on behalf of the Partnership in respect of a Major Decision unless and until at least one Stratus Representative and at least one Olympus Representative have authorized the same in writing. 4.4 Budgets and Reports. (a) By November 1st of each calendar year hereafter during the term hereof, the Operating Partner shall prepare a revised Operating Budget and Business Plan for the operation of the Partnership for the next succeeding calendar year of the Partnership. The Management Committee shall have thirty (30) days after receipt thereof to either approve the submitted Business Plan and Operating Budget or respond with required changes to same. A copy of the initial Business Plan is attached hereto as Exhibit A and a copy of the initial Operating Budget is attached hereto as Exhibit B. (b) The Operating Partner agrees to use diligence and to employ all reasonable efforts to ensure that the actual costs of operating the Partnership shall not exceed the Operating Budget, either in total or for any one accounting category. The Operating Partner shall secure the written approval of the Management Committee for any expenditure that (i) exceeds fifteen percent (15%) of the annual budgeted amount for the Partnership in any one accounting category on such Operating Budget or (ii) exceeds ten percent (10%) of the annual budgeted amount for the Partnership in all accounting categories of the Operating Budget. During each applicable calendar year, the Operating Partner agrees to promptly inform the Management Committee of any material increases in costs and expenses or any material decreases in revenue that were not foreseen during the budget preparation period and thus were not reflected in the Operating Budget. (c) In addition to the reports further described in Section 8.4, the Operating Partner shall submit any additional financial or operational reports as the Financial Partner may from time to time reasonably request. 4.5 Powers of the Operating Partner. Subject to Section 4.3, the Operating Partner shall have the duties, rights and obligations to implement the operations of the Partnership as described in the Business Plan, Operating Budget or approved in writing by the Management Committee. Without limiting the generality of Section 4.1, but subject to Section 4.2(c) and Section 4.3, the Operating Partner, acting on behalf of the Partnership, shall oversee the development activities with respect to the Property as well as the activities of the property manager and the construction manager; provided, that if there is no property manager, the Operating Partner shall perform the duties and obligations of a property manager; provided, further, that neither the Operating Partner nor any Affiliate thereof shall take any action that has a material economic affect on the Partnership without the prior approval of the Management Committee, including, without limitation, approving the form and substance of all leases, contracts, loan documents or other documents necessary to operate the business of the Partnership. 4.6 Liability of Partners. The Partners shall be personally liable for the debts and obligations of the Partnership if (but solely to the extent) required by applicable law; provided, however, that all such debts and obligations shall be paid or discharged first with the property of the Partnership (including insurance proceeds) before the Partners shall be obligated to pay or discharge any such debts or obligations with their personal assets. Notwithstanding the preceding sentence, the Partners shall not be personally liable for any debts or obligations which are nonrecourse or which, under the terms thereof, do not create or impose such liability. For purposes hereof, any obligations arising under the Indemnity Agreement and/or the Management Agreement shall be treated as nonrecourse obligations and Stratus agrees and acknowledges that, except as expressly provided to the contrary in Section 3.2(a) hereof with respect to any Guaranty Payment, no Partner shall have any obligation to make any Capital Contribution to the Partnership or any other payment in order to satisfy any obligation arising under the Indemnity Agreement and/or the Management Agreement. 4.7 Other Activities of Partners. Except as otherwise agreed in writing, each Partner (i) may carry on and conduct in any way or in any capacity, including, but not limited to, for such Partner's own right and for such Partner's own personal account, as a partner in any other partnership, as a venturer in any joint venture, as a member or manager in any limited liability company, as an employee, officer, director or stockbroker of any corporation, or as a participant in any syndicate, pool, trust, association or other business organization, a business that competes, directly or indirectly, with the business of the Partnership, (ii) will be free in any capacity to conduct business activities the same or similar as conducted by the Partnership and (iii) may make investments in any kind of property. The Partnership will have absolutely no claim or right to any such business or assets thereof. Further, the Partnership will have claim to and will own only those assets contributed to the Partnership or acquired with Partnership funds or credit. Neither this Agreement nor any principle of law or equity shall preclude or limit, in any respect, the right of any Partner or any affiliate thereof to engage in or derive profit or compensation from any activities or investments, nor give any other Partner any right to participate or share in such activities or investments or any profit or compensation derived therefrom. ARTICLE 5 Exculpation and Indemnity 5.1 Exculpation. Except as expressly provided to the contrary herein, neither the Partners nor any Affiliate of the Partners, nor any officer, director, manager, member, employee, agent, stockholder, or partner of the Partners or any of its Affiliates, shall be liable, responsible, or accountable in damages or otherwise to the Partnership or any Partner by reason of, or arising from or relating to the operations, business, or affairs of, or any action taken or failure to act on behalf of, the Partnership, except to the extent that any of the foregoing is determined, to have been primarily caused by the negligence, willful misconduct, or bad faith of the person claiming exculpation. 5.2 Indemnity. The Partnership shall indemnify the Partners, each Affiliate of the Partners, and each officer, director, stockholder, manager, member, and partner of the Partners or any of its Affiliates, and if so determined by the Partners, each employee or agent of the Partners or any of its Affiliates, against any claim, loss, damage, liability, or expense (including reasonable attorneys' fees, court costs, and costs of investigation and appeal) suffered or incurred by any such indemnitee by reason of, or arising from or relating to the operations, business, or affairs of, or any action taken or failure to act on behalf of, the Partnership, except to the extent any of the foregoing (i) is primarily caused by the negligence (which for purposes of this Agreement shall not include the provision or withholding of any consent or approval by the Partner or its Representative with respect to any matter under this Agreement), willful misconduct, or bad faith of the person claiming indemnification or constitutes a material breach of any provision of the Guaranty, this Agreement, the Management Agreement or the Assignment Agreement (including, without limitation, any breach of any representation, warranty or covenant of Stratus further set forth in the Assignment Agreement), or (ii) is suffered or incurred as a result of any claim (other than a claim for indemnification under this Agreement) asserted by the indemnitee as plaintiff against the Partnership. Unless a determination has been made that indemnification is not required, the Partnership shall, upon the request of any indemnitee, advance or promptly reimburse such indemnitee's reasonable costs of investigation, litigation, or appeal, including reasonable attorneys' fees; provided, however, that the affected indemnitee shall, as a condition of such indemnitee's right to receive such advances and reimbursements, certify its good faith belief that it is entitled to indemnification hereunder, undertake in writing to repay promptly the Partnership for all such advancements or reimbursements if a court of competent jurisdiction determines that such indemnitee is not then entitled to indemnification under this Section 5.2 and provide the Partnership with reasonable assurances of performance with respect to the obligation to repay such amounts. No Partner shall be required to contribute capital to the Partnership in respect of any indemnification claim under this Section 5.2. ARTICLE 6 Distributions and Allocations 6.1 Distributions. (a) Subject to the provisions of Section 3.2(e) and Section 6.1(c) hereof, unless and until the Partnership shall commence the development of the Phase II Property (as described in Section 3.5(e) hereof), in which event distributions of Partnership Cash Flow shall be made in accordance with Section 6.1(b) hereof, any and all Cash Flow of the Partnership shall be distributed in accordance with this Section 6.1(a). No later than thirty (30) days after the end of each Distribution Period during which the Partnership has Cash Flow, such Cash Flow shall be distributed, after the payment of all third party obligations (which third party obligations shall not include any amounts owing any Partner or Affiliate thereof with respect to any Partnership indebtedness or any amounts owing Stratus under the Indemnity Agreement), in the following order of priority: (i) first, to Stratus in an amount equal to any unpaid amounts owing Stratus under the Indemnity Agreement; (ii) second, to the Partners and their Affiliates in an amount equal to any accrued and unpaid interest and/or any unpaid principal amounts with respect to any Partnership indebtedness owing any such Partners or their Affiliates; (iii) third, to the Partners, pro rata, in accordance with their respective Sharing Ratios until each Partner shall have received aggregate distributions under this Section 6.1(a)(iii) equal to an IRR of 25%; (iv) fourth, to Stratus until Stratus has received an aggregate amount equal to $1,065,000 under this Section 6.1(a)(iv); and (v) fifth, to the Partners, pro rata, in accordance with their respective Sharing Ratios. (b) Subject to the provisions of Section 3.2(e) and Section 6.1(c) hereof, notwithstanding the provisions of Section 6.1(a) hereof to the contrary, upon the date that the Partnership shall commence development of the Phase II Property (as described in Section 3.5(e) hereof) and during all periods of the Partnership thereafter, any and all Cash Flow of the Partnership shall be distributed in accordance with this Section 6.1(b). No later than thirty (30) days after the end of each Distribution Period during which the Partnership has Cash Flow, such Cash Flow shall be distributed, after the payment of all third party obligations (which third party obligations shall not include any amounts owing any Partner or any Affiliate thereof with respect to any Partnership Indebtedness or any amounts owing Stratus under the Indemnity Agreement), in the following order of priority: (i) first, to Stratus in an amount equal to any unpaid amounts owing Stratus under the Indemnity Agreement; (ii) second, to the Partners and their Affiliates in an amount equal to any accrued and unpaid interest and/or any unpaid principal amounts with respect to any Partnership indebtedness owing any such Partners or their Affiliates; and (iii) third, to the Partners, pro rata, in accordance with their respective Sharing Ratios. (c) In accordance with Section 11.15 of the Assignment Agreement, each of Stratus and STRS have agreed to indemnify Olympus and hold Olympus harmless from certain Losses (as defined in the Assignment Agreement) incurred by Olympus and its Affiliates (as defined in the Assignment Agreement). Stratus hereby agrees and acknowledges that, in addition to any other remedies available to Olympus under any other provision of this Agreement, the Assignment Agreement or at law or in equity, in the event that Stratus or STRS shall have any obligation to Olympus under Section 11.15 of the Assignment Agreement (an "Indemnification Obligation"), the Partnership shall not distribute or pay to Stratus, Stratus Management, or their respective Affiliates, any amount that would otherwise be distributable or payable to Stratus, Stratus Management, or their respective Affiliates (including, without limitation, any amounts of Cash Flow otherwise distributable to Stratus or its Affiliates under this Section 6.1 as well as any fees payable by the Partnership to Stratus, Stratus Management or their respective Affiliates, including, without limitation, the Phase I Asset Management Fee, the Phase II Asset Management Fee and any applicable Disposition Fees), and such amounts shall instead be paid by the Partnership to Olympus and applied to the discharge of such Indemnification Obligation, provided that the application of such amounts to any such Indemnification Obligation shall not release Stratus and STRS of their obligation to indemnify and hold Olympus harmless from and against any and all Losses in accordance with the provisions of Section 11.15 of the Assignment Agreement. Any amounts otherwise distributable or payable by the Partnership to Stratus, Stratus Management or their respective Affiliates that are instead paid to Olympus hereunder and applied toward the discharge of any Indemnification Obligation shall be treated, for all purposes under this Agreement as distributions or payments (as the case may be, based upon the amount of the payment and the priority of payment provided under the other provisions of this Agreement) to Stratus, Stratus Management and/or their respective Affiliates. 6.2 Tax Allocations. For United States federal income tax purposes, allocations of items of income, gain, loss, deduction, expense, and credit for each fiscal year of the Partnership shall be in accordance with each Partner's economic interest in the respective item, as determined by the Management Committee pursuant to Section 704(b) of the Code, and the regulations promulgated thereunder and subject to the requirements of Section 704(c) of the Code and the regulations promulgated thereunder. Unless the Management Committee determines otherwise, allocations shall be made to each Partner (i) in the same manner as such Partner would be required to contribute to the Partnership or (ii) in such manner as shall result in the Capital Account of each Partner having a balance equal to the aggregate distributions the Partner would receive if the Partnership were to liquidate the assets of the Partnership at their book value and distribute the proceeds in accordance with Section 6.1; provided, however, that if any such allocation is not permitted by applicable law, the Partnership's subsequent income, gain, loss, deduction, expense and credit shall be allocated among the Partners so as to reflect as nearly as possible the allocation used in computing Capital Accounts. 6.3 Asset Management Services. From and after the Effective Date, until the termination of the Management Agreement, Stratus Management shall provide the asset management services to the Partnership further described in the attached Schedule II (the "Asset Management Services") with respect to the Property, in consideration for the accrual and/or payment of the fees further set forth in this Section 6.3. In consideration for its provision of the Asset Management Services with respect to the Phase I Property Stratus Management shall be paid a monthly asset management fee equal to $5,000 per month (the "Phase I Asset Management Fee") upon the terms and conditions set forth in this Section 6.3. The Phase I Asset Management Fee shall begin to accrue with respect to the Phase I Property at such time as a certificate of occupancy shall have been issued for the Phase I Property by the City of Austin, and all development fees shall have been paid; provided, however, that the Phase I Asset Management Fee shall not be payable by the Partnership to Stratus Management unless and until a tenant, other than the Partnership, any Partner or any Affiliate thereof shall take physical possession of a portion of the Phase I Property pursuant to a lease between such tenant and the Partnership that has been approved by the Management Committee. In consideration for its provision of the Asset Management Services with respect to the Phase II Property, Stratus Management shall be paid a monthly asset management fee (in addition to the Phase I Asset Management Fee) equal to $2,500 per month (the "Phase II Asset Management Fee"). The Phase II Asset Management Fee shall begin to accrue with respect to the Phase II Property at such time as a certificate of occupancy shall have been issued for the Phase II Property by the City of Austin and all development fees have been paid; provided, however, that the Phase II Asset Management Fee shall not be payable by the Partnership to Stratus Management unless and until a tenant, other than the Partnership, any Partner or any Affiliate thereof shall take physical possession of a portion of the Phase II Property pursuant to a lease between such tenant and the Partnership that has been approved by the Management Committee. Any accrued fees that become payable to Stratus Management hereunder shall be paid by the Partnership monthly in arrears and shall constitute guaranteed payments to Stratus as further described in Section 707(c) of the Code. 6.4 Disposition Services. Upon the sale by the Partnership of all or substantially all of the Property (a "Terminal Sale") to a third-party buyer (who shall not be a Partner or Affiliate of a Partner), a sales commission of 2% of the gross sale price (the "Disposition Fee") shall be paid to the Partner or a duly licensed Affiliate or representative of the Partner who procured such third-party buyer (the "Procuring Party"); provided, however, that, no Disposition Fee shall be payable to the Procuring Party in the event that (i) the Partnership shall have retained any broker or representative that is entitled to a commission with regard to the Terminal Sale, (ii) the third party buyer shall have initiated contact with the Partnership or any Partner or Affiliate or representative thereof without prior independent solicitation by the Procuring Party or (iii) the third party buyer otherwise shall have contacted the Partnership or any Partner or Affiliate or representative thereof or have been identified other than through the marketing efforts and solicitation of the Procuring Party. Any Disposition Fee payable to a Partner hereunder shall constitute a guaranteed payment to the Partner as further described in Section 707(c) of the Code. 6.5 No Other Fees. Except as otherwise expressly provided herein to the contrary or as otherwise expressly provided to the contrary in the Management Agreement or as may be unanimously approved by the Partners in writing, the Partners and their Affiliates shall not be paid any fees or other compensation by the Partnership. ARTICLE 7 Admissions, Transfers and Withdrawals 7.1 Admission of New Partners. Except as expressly provided to the contrary herein, after the Effective Date, new Partners may be admitted to the Partnership only with the written consent of, and upon such terms and conditions as are approved by the unanimous approval of the Management Committee. No admission of any new Partner shall cause the Partner's interest in Partnership allocations, distributions and capital to be less than one percent (1%), and no Partner's Sharing Ratio in the Partnership shall be reduced or diluted unless approved in writing by such Partner. 7.2 Transfer of Partnership Interests. No Partner may transfer or encumber all or any portion of such Partner's interest in the Partnership without the prior written consent of the Management Committee; provided, however, that Olympus may transfer all or any portion of its interest in the Partnership to an Affiliate of Olympus Real Estate Corporation without the consent of the Management Committee or Stratus; and provided, further, that Stratus may transfer all or any portion of its interest in the Partnership to a wholly-owned subsidiary of Stratus Properties, Inc., a Delaware corporation, without the consent of the Management Committee or Olympus. Additionally, any interest in the Partnership held by Olympus or its Affiliates may be transferred without the consent of the Management Committee or Stratus in connection with the exercise of the rights of the limited partners of Olympus Real Estate Fund II, L.P. ("Fund II") to remove the general partner under the limited partnership agreement of Fund II. As soon as reasonably practicable following any transfer that is permitted hereunder, the Management Committee shall amend the Partnership Agreement (and Schedule I hereof) to reflect the Capital Account balance, Contribution Percentage, Unreturned Capital Contributions and Sharing Ratios of the Partners and the admission of the transferee to the Partnership as a Partner. 7.3 Buy/Sell Option. (a) At any time during the term of the Partnership, either Partner may exercise a "buy-sell" right (the "Buy-Sell") as follows: either Partner (the "Offeror") exercising such Buy-Sell (A) shall deliver to the other Partner (the "Offeree") a written notice (the "Buy/Sell Offer") stating the Offeror's exercise of such right and setting forth the Buy/Sell Offer and a description of any negotiations or discussions with third parties that Offeror or its Affiliates may have had with respect to the sale of all or any portion of the Partnership Interest and/or the Business, which Buy/Sell Offer shall represent the dollar amount (without reduction for any deemed or imputed expenses of sale) that the Offeror would be willing to pay to the Partnership in cash for the Business (the "Offer Amount") and (B) simultaneously with the delivery of the Buy/Sell Offer, shall deliver into escrow with a title insurance company located in Dallas, Texas selected by the Offeror (the "Escrow Agent"), a good faith deposit in the amount of the Offer Deposit. The Offeror hereby instructs the Escrow Agent that the Escrow Agent shall either (i) in the event the Offeree elects to sell its interest in the Partnership (the "Partnership Interest") in accordance with the terms hereof, apply such Offer Deposit to the purchase price as of the Buy/Sell Closing Date (as hereinafter defined) or if the Offeror fails to timely purchase the Offeree's Partnership Interest in accordance with the terms hereof, disburse such Offer Deposit in accordance with Section 7.3(g), or (ii) in the event the Offeree elects to purchase the Offeror's Partnership Interest, disburse such Offer Deposit in accordance with Section 7.3(e). (b) The notice transmitting the Buy/Sell Offer shall be deemed to constitute an offer by the Offeror to purchase the Offeree's Partnership Interest for a price equal to the Receipt Amount. "Receipt Amount" shall mean the aggregate amount which the Partner whose Partnership Interest is to be transferred, whether Offeror or Offeree (or pursuant to Section 7.3(g), the Buy/Sell Purchaser), would receive as a Partnership distribution if (i) the Business were sold for cash for the Offer Amount, (ii) all debts and liabilities of the Partnership but without taking into account any deemed or imputed expenses which would occur for the sale to third parties (e.g. imputed brokerage fees, etc.) were paid in full from such proceeds in the order of priority further set forth in this Agreement, and (iii) prorations were made with respect to all current assets and current liabilities of the Partnership. (c) The Offeree shall have forty-five (45) days from the date of the Buy/Sell Offer to elect, by written notice to the Offeror signed by the Partner constituting the Offeree, whether to sell such Offeree's Partnership Interest to the Offeror or whether to purchase (or cause its designee to purchase) the Offeror's Partnership Interest in the Partnership (the "Buy/Sell Election Period"). (d) If the Offeree fails to make an election within such forty-five (45) day period, or fails to comply with subsection (e) below, such Offeree shall be conclusively deemed to have elected to sell its Partnership Interest in the Partnership to the Offeror according to the terms of this Section 7.3. (e) If the Offeree makes an election to purchase within such forty-five (45) day period by sending written notice to the Offeror as required by subsection (c), and by delivering into escrow with the Escrow Agent a good faith deposit in the amount of the Offer Deposit, then, the original Offeror shall be conclusively deemed to have elected to sell its Partnership Interest in the Partnership to the Offeree for a price equal to the applicable Receipt Amount. In the event the Offeree timely makes an election to purchase, the Offeree hereby instructs the Escrow Agent that the Escrow Agent shall (i) return the Offeror's Offer Deposit to the Offeror and (ii) hold the Offeree's Offer Deposit and shall either apply such Offeree's Offer Deposit to the purchase price as of the Buy/Sell Closing Date (as hereinafter defined) or disburse such Offeree's Offer Deposit in accordance with Section 7.3(g). (f) The Partner (the "Buy/Sell Purchaser") that is obligated to purchase the Partnership Interest in the Partnership of the other Partner (the "Buy/Sell Seller") pursuant to this Section 7.3 shall fix a closing date (the "Buy/Sell Closing Date") for such purchase that shall be a Business Day that is not later than forty-five (45) days after the expiration of the Buy/Sell Election Period, by written notice to the Buy/Sell Seller at least fifteen (15) days in advance of the Buy/Sell Closing Date. The closing of such purchase shall take place on the Buy/Sell Closing Date at the address of the Escrow Agent. At such closing, the Partner constituting the Buy/Sell Seller shall execute and deliver to the Buy/Sell Purchaser (or its designee) such instruments of assignment, bills of sale, amendments to this Agreement and other instruments and documents as the Buy/Sell Purchaser and the Buy/Sell Seller (or such designee) may reasonably require for the conveyance to such Buy/Sell Purchaser (or such designee) of all of the Buy/Sell Seller's right, title and interest in and to the Buy/Sell Seller's Partnership Interest in the Partnership against receipt by the Buy/Sell Seller of a wire transfer of immediately available funds in an amount equal to the applicable Receipt Amount; and the Buy/Sell Seller hereby irrevocably constitutes and appoints the Buy/Sell Purchaser as its attorneyin- fact to execute, acknowledge and deliver any of such instruments or documents. Each of the Buy/Sell Seller and Buy/Sell Purchaser shall each bear their respective closing costs and expenses (including, but not limited to, all attorney's fees and costs and all applicable transfer and income taxes) incurred in the purchase or sale of the Buy/Sell Seller's Partnership Interest in the Partnership hereunder. Such sale of such Partnership Interest shall be made without representation, warranty or recourse, except for representations and warranties in form and substance reasonably acceptable to the Buy/Sell Purchaser and the Buy/Sell Seller with respect to existence, good standing, title, no encumbrance, authority, authorization, no conflicts, and such other customary matters as may be reasonably requested by the Buy/Sell Purchaser. If the Buy/Sell Offer or the closing of the purchase contemplated thereby causes the maturity of any Partnership indebtedness to be accelerated, the Buy/Sell Seller shall be released from liability resulting from such accelerated indebtedness and the Buy/Sell Purchaser shall pay (or cause to be paid) such indebtedness in full (including without limitation, any accrued but unpaid interest and any prepayment premiums or penalties) at Buy/Sell Purchaser's sole cost and expense and shall indemnify and hold Buy/Sell Seller harmless from and against any losses, damages, costs or expenses (including attorneys' fees) incurred by Buy/Sell Seller, or the Buy/Sell Seller's Affiliates, employees, agents, representatives, consultants, attorneys, fiduciaries, servants, officers, directors, partners, predecessors, successors and assigns and Affiliates of the foregoing (the "Indemnified Parties"), as a direct or indirect result of any such acceleration, other than any losses, damages, costs or expenses (including attorneys' fees) incurred by any of the Indemnified Parties as a direct result of such Indemnified Party's gross negligence, willful misconduct or bad faith. As a precondition to the closing of the Buy/Sell transaction, the Buy/Sell Seller shall be released from liability from any indebtedness of the Partnership, including, without limitation, the release of any guaranty and collateral pledged to secure any guaranty debt. Anything contained in this Agreement to the contrary notwithstanding, in the event the sale of the Partnership Interest is not consummated because of a default on the part of Buy/Sell Seller or if a condition precedent cannot be fulfilled because Buy/Sell Seller frustrated such fulfillment, Buy/Sell Purchaser may, at its election, pursue an action for specific performance and/or damages, costs and expenses. (g) In the event that the Buy/Sell Purchaser defaults in its obligation to purchase the Partnership Interest of the Buy/Sell Seller in the Partnership on the Buy/Sell Closing Date, the Buy/Sell Seller shall have the right to (i) solicit third party offers on behalf of the Partnership for the purchase of the Business, to accept the best such offer, as determined by the Buy/Sell Seller in its sole and absolute discretion, and to consummate the sale of the Business to such third party pursuant to such offer, (ii) purchase the Partnership Interest of the Buy/Sell Purchaser for a purchase price equal to ninety percent (90%) of the Receipt Amount with respect to the Partnership Interest of the Buy/Seller Purchaser, (iii) specifically enforce the Buy/Sell Purchaser's obligation to purchase the Partnership interest of the Buy/Sell Seller, and (iv) notify the Escrow Agent holding the Offer Deposit of the Buy/Sell Purchaser immediately to deliver such Offer Deposit to the Buy/Sell Seller as liquidated damages for the breach by such Buy/Sell Purchaser (and the Buy/Sell Purchaser covenants and agrees to cause, and hereby instructs, the Escrow Agent to deliver such Offer Deposit to the Buy/Sell Seller). The delivery of the Offer Deposit to the Buy/Sell Seller shall not constitute a return of capital or a Partnership distribution. The Buy/Sell Purchaser hereby constitutes and appoints the Buy/Sell Seller as its attorney-in-fact to execute and deliver on behalf of the Buy/Sell Purchaser all documents as may be reasonably required in connection with the delivery by the Escrow Agent of the Offer Deposit to the Buy/Sell Seller in accordance with this Section 7.3. 7.4 No Substituted Partners. Except as permitted by Section 7.1 and subject to the provisions of Section 7.2, no transferee of any partnership interest in the Partnership may become a substituted Partner. Rather, any transferee of any Partnership interest of a Partner shall be entitled solely to rights as assignee of the rights to receive all or part of the share of the income, gains, losses, deductions, expenses, credits, distributions, or returns of capital to which his or its transferor would otherwise be entitled with respect to the Partnership interest so transferred. 7.5 Withdrawal of Partners. Except as permitted by Section 7.2 hereof, no Partner shall have any right to withdraw or resign from the Partnership without the unanimous consent of the Management Committee. ARTICLE 8 General Accounting Provisions, Books and Reports 8.1 Books of Account; Tax Returns. The Financial Partner shall prepare and file, or shall cause to be prepared and filed, all United States federal, state, and local income and other tax returns required to be filed by the Partnership and shall keep or cause to be kept complete and appropriate records and books of account in which shall be entered all such transactions and other matters relative to the Partnership's operations, business and affairs as are usually entered into records and books of account that are maintained by persons engaged in business of like character or are required by the Act. The Financial Partner shall have the authority to make any and all federal or state tax elections with respect to the Partnership and its Business. In addition, the Partners agree and acknowledge that the Partnership shall make an election under Section 754 of the Code with respect to its 1999 taxable year, and more particularly, with regard to the Assignments. Except as otherwise expressly provided herein, the books and records of the Partnership shall be maintained in accordance with the basis utilized in preparing the Partnership's United States federal income tax returns, which returns, if allowed by applicable law, shall be prepared on an accrual basis. 8.2 Place Kept; Inspection. The books and records shall be maintained at the principal place of business of the Partnership, and all such books and records shall be available for inspection and copying at the reasonable request, and at the expense, of any Partner during the ordinary business hours of the Partnership. 8.3 Tax Matters Partner. The Financial Partner shall be the tax matters partner of the Partnership and, in such capacity, shall exercise all rights conferred, and perform all duties imposed, upon a tax matters partner under Sections 6221 through 6233 of the Code and the regulations promulgated thereunder. Notwithstanding the foregoing, the Financial Partner shall have the right to select the methodology to be used pursuant to Section 704(c) of the Code. 8.4 Additional Reporting Requirements. In addition to any reports required under Section 4.4(c) hereof: (a) Stratus shall deliver to each Partner within twenty (20) days of the end of each month a statement of receipts and disbursements relating to the Property, and on a quarterly basis a narrative report on all variances from the Business Plan or Operating Budget, pacing against the Construction Loan, and all construction, leasing and marketing activities affecting the Property, and such other reports as reasonably requested by Olympus.

Such reports shall contain a balance sheet as of the end of the fiscal year, an income statement and statement of changes in financial position for the fiscal year. (c) If requested by Olympus, the financial statements referred to in Section 8.4(b) shall be accompanied by the report thereon, if any, of Arthur Andersen & Co. or such other accountant as may be designated by the Management Committee. ARTICLE 9 Amendments and Waivers 9.1 Amendments and Waivers. Except as expressly provided in Section 9.2 of this Agreement, the Management Committee may amend or waive any provision of this Agreement which merely (i) corrects an error or clarifies an ambiguity in this Agreement, (ii) does not adversely affect the Financial Partner or the Operating Partner in any material respect or (iii) changes Schedule I to this Agreement to reflect the Capital Account balances, Contribution Percentages, Unreturned Capital Contributions, Sharing Ratios and/or Partnership Interests of the Partners as from time to time amended in accordance with this Agreement. The Management Committee shall amend Schedule I to this Agreement to reflect any additional Capital Contributions; provided, however, that upon any failure of a Defaulting Partner to repay the Default Amount to the Non Defaulting Partners within the one hundred twenty (120) day term further described in the first sentence of Section 3.2(c), the Non-Defaulting Partners shall have complete power and authority, acting singly and without necessity of joinder of any other Partner to amend Schedule I to accurately reflect the Capital Contributions, Sharing Ratios and Contribution Percentages of the Partners. The Partners agree to look to the books and records of the Partnership for determination of the actual amount of Capital Contributions made to the Partnership, as provided in Section 3.1 and Section 3.2 of this Agreement. 9.2 Certain Other Amendments. Notwithstanding any provision to the contrary contained herein, no amendment to or waiver of any provision of this Agreement shall be effective against a given Partner without the consent or vote of such Partner if such amendment or waiver would (i) cause the Partnership to fail to be treated as a partnership for federal income tax purposes or under the Act, (ii) change Section 3.1 or Section 3.2 of this Agreement to increase a Partner's obligation to contribute to the capital of the Partnership, (iii) change Section 5.1, or 5.2 of this Agreement to affect adversely any Partner's rights to exculpation or indemnification, (iv) change Section 6.1 or 6.2 of this Agreement to affect adversely the participation of such Partner in the income, gains, losses, deductions, expenses, credits, capital or distributions of the Partnership (but excluding any amendments to Schedule I hereof to accurately reflect the Capital Account balances, Contribution Percentages, Unreturned Capital Contributions, Sharing Ratios and/or Partnership Interests of the Partners following any failure of a Defaulting Partner to timely repay the Default Amount to the Non-Defaulting Partners, as further described in Section 3.2(c) or any transfer of a Partnership Interest expressly permitted pursuant to the provisions of Section 7.2 hereof), (v) change Section 7.1 of this Agreement to affect adversely the anti-dilution rights of such Partner, (vi) change the percentage of Partners necessary for any consent or vote required hereunder to the taking of any action (provided, that the provisions of this Section 9.2 shall have no affect upon the loss of voting rights hereunder of a Defaulting Partner or its Representatives under Section 3.2(b)) or (vii) amend this Section 9.2 of this Agreement.

Notwithstanding the foregoing, the business and affairs of the Partnership shall not be wound up upon the occurrence of an event specified in (iii) through (vi) of this Section 10.1, if within ninety (90) days after such occurrence 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 Financial Partner. 10.2 Accounting Upon Winding Up. Following the occurrence of an event requiring the winding up of the business and affairs of the Partnership pursuant to Section 10.1 of this Agreement (and, if applicable, the failure of a majority in interest of the remaining Partners to continue the business of the Partnership in accordance with Section 10.1), the books of the Partnership shall be closed, and a proper accounting of the Partnership's assets, liabilities and operations shall be made by the Financial Partner, all as of the most recent practicable date. The Financial Partner shall serve as the liquidator of the Partnership unless it has been removed or unless it otherwise fails or refuses to serve. If the Financial Partner does not serve as the liquidator, one or more other persons or entities may be selected to serve by the Operating Partner. The expenses incurred by the liquidator in connection with the dissolution, liquidation and termination of the Partnership shall be borne by the Partnership. 10.3 Termination. As expeditiously as practicable, but in no event later than one year (except as may be necessary to realize upon any material amount of property that may be illiquid), after the occurrence of an event requiring the winding up of the business and affairs of the Partnership pursuant to Section 10.1 of this Agreement, the liquidator shall cause the Partnership to pay the current liabilities of the Partnership (other than any liabilities or obligations of the Partnership under the Indemnity Agreement or with respect to any Partnership indebtedness owed to any Partner or Affiliate thereof which shall be repaid in the order of priority further set forth in Section 6.1 hereof) and (i) establish a reserve fund (which may be in the form of cash or other property, as the liquidator shall determine) for any and all other liabilities, including contingent liabilities, of the Partnership in a reasonable amount determined by the liquidator to be appropriate for such purposes or (ii) otherwise make adequate provision for such other liabilities. To the extent that cash required for the foregoing purposes is not otherwise available, the liquidator may sell property, if any, of the Partnership for cash. Thereafter, all remaining cash or other property, if any, of the Partnership shall be distributed to the Partners in accordance with the provisions of Section 6.1 of this Agreement. The Partners must agree on the value and distributee for all in kind distributions or else all property must be sold and the proceeds therefrom distributed in accordance herewith. At the time final distributions are made in accordance with Section 6.1 of this Agreement, the liquidator shall make any and all such filings as the liquidator shall determine to be appropriate to cause or evidence the termination of the Partnership, and the legal existence of the Partnership shall terminate, but if at any time thereafter any reserved cash or property is released because in the judgment of the liquidator the need for such reserve has ended, then such cash or property shall be distributed in accordance with Section 6.1 of this Agreement. 10.4 No Negative Capital Account Obligation. Notwithstanding any other provision of this Agreement to the contrary, in no event shall any Partner who has a negative capital account upon final distribution of all cash and other property of the Partnership be required to restore such negative account to zero. 10.5 No Other Cause of Dissolution. The Partnership shall not be dissolved, or its legal existence terminated, for any reason whatsoever except as expressly provided in this Article 10. 10.6 Merger.
