Except as otherwise provided in Section 1.704-2(i)(4) of the Regulations, notwithstanding any other provision of this Article 3, if there is a net decrease in Partner Nonrecourse Debt Minimum Gain attributable to a Partner Nonrecourse Debt during any Allocation Year, each Partner who has a share of the Partner Nonrecourse Debt 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 Allocation Year (and, if necessary, subsequent Allocation

Years) in an amount equal to such Partner’s share of the net decrease in Partner Nonrecourse Debt Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Section 1.704-2(i)(4) of the Regulations. Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Partner pursuant thereto. The items to be so allocated shall be determined in accordance with Section 1.704-2(i)(4) and Section 1.704-2(j)(2) of the Regulations. This Section 3.2(b) is intended to comply with the minimum gain chargeback requirement in Section 1.704-2(i)(4) of the Regulations and shall be interpreted consistently therewith.

(c) Qualified Income Offset. In the event any Limited Partner unexpectedly receives any adjustments, allocations, or distributions described in Section 1.704- l(b)(2)(ii)(d)(4), Section 1.704-1(b)(2)(ii)(d)(5) or Section 1.704-1(b)(2)(ii)(d)(6) of the Regulations, items of Partnership income and gain shall be specially allocated to each such Limited Partner in an amount and manner sufficient to eliminate, to the extent required by the Regulations, the Adjusted Capital Account Deficit of such Limited Partner as quickly as possible, provided that an allocation pursuant to this Section 3.2(c) shall be made only if and to the extent that such Limited Partner would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article 3 have been tentatively made as if this Section 3.2(c) were not in the Agreement.

(d) Gross Income Allocation. In the event any Limited Partner has a deficit Capital Account at the end of any Allocation Year which is in excess of the sum of (i) the amount such Limited Partner is obligated to restore pursuant to any provision of this Agreement, and (ii) the amount such Limited Partner is deemed to be obligated to restore pursuant to the penultimate sentences of Section 1.704-2(g)(l) and Section 1.704-2(i)(5) of the Regulations, each such Limited Partner shall be specially allocated items of Partnership income and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 3.2(d) shall be made only if and to the extent that such Limited Partner would have a deficit Capital Account in excess of such sum after all other allocations provided for in this Article 3 have been made as if Section 3.2(c) and this Section 3.2(d) were not in the Agreement.

(e) Partner Nonrecourse Deductions. Any Partner Nonrecourse Deductions for any Allocation Year shall be specially allocated to the Partner who bears the economic risk of loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Section 1.704-2(i)(l) of the Regulations.

(f) Nonrecourse Deductions. Nonrecourse Deductions for any Allocation Year shall be specially allocated among the Partners in proportion to their Percentage Interests.

(g) Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or Section 743(b) of the Code is required pursuant to Section 1.704-1(b)(2)(iv)(m)(2) or Section 1.704-1(b)(2)(iv)(m)(4) of the Regulations to be taken into account in determining Capital Accounts as the result of a distribution to a Partner in complete liquidation of its Interest, the amount of such adjustment to 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 to the Partners in accordance with their interests in the Partnership in the event Section 1.704-l(b)(2)(iv)(m)(2) of the Regulations applies, or to the Partner to whom such distribution was made in the event Section 1.704-l(b)(2)(iv)(m)(4) of the Regulations applies.

(h) Allocations Relating to Taxable Issuance of Partnership Interests. Any income, gain, loss, or deduction realized as a direct or indirect result of the issuance of an Interest by the Partnership to a Partner (the “Issuance Items”) shall be allocated among the Partners so that, to the extent possible, the net amount of such Issuance Items, together with all other allocations under this Agreement to each Partner, shall be equal to the net amount that would have been allocated to each such Partner if the Issuance Items had not been realized.

Section 3.3 Curative Allocations. The allocations set forth in Section 3.2(a) through Section 3.2(g) (the “Regulatory Allocations”) are intended to comply with certain requirements of the Regulations. It is the intent of the Partners that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory Allocations or with special allocations of other items of Partnership income, gain, loss, or deduction pursuant to this Section 3.3. Therefore, notwithstanding any other provision of this Article 3 (other than the Regulatory Allocations), the General Partner shall make such offsetting special allocations of Partnership income, gain, loss, or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made, each Partner’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Partner would have had if the Regulatory Allocations were not part of the Agreement and all Partnership items were allocated pursuant to Section 3.1 and Section 3.2(h). In exercising its discretion under this Section 3.3, the General Partner shall take into account future Regulatory Allocations under Section 3.2(a) and Section 3.2(b) that, although not yet made, are likely to offset other Regulatory Allocations previously made under Section 3.2(e) and Section 3.2(f).

Section 3.4 Loss Limitation. Losses allocated pursuant to Section 3.l(b) hereof shall not exceed the maximum amount of losses that can be allocated without causing any Limited Partner to have an Adjusted Capital Account Deficit at the end of any Allocation Year. All Losses in excess of the limitations set forth in this Section 3.4 shall be allocated to the General Partner.

(a) Profits, Losses and any other items of income, gain, loss or deduction shall be allocated to the Partners pursuant to this Article 3 as of the last day of each Allocation Year; provided that Profits, Losses and such other items shall also be allocated at such times as the Gross Asset Values of Partnership Property are adjusted pursuant to subparagraph (ii) of the definition of Gross Asset Value in Section 1.9.

(b) For purposes of determining the Profits, Losses, or any other items allocable to any period, Profits, Losses, and any such other items shall be determined on a daily, monthly, or other basis, as determined by the General Partner using any permissible method under Section 706 of the Code and the Regulations thereunder.

(c) The Partners are aware of the income tax consequences of the allocations made by this Article 3 and hereby agree to be bound by the provisions of this Article 3 in reporting their shares of Partnership income and loss for income tax purposes, except to the extent otherwise required by law.

(d) Solely for purposes of determining a Partner’s proportionate share of the “excess nonrecourse liabilities” of the Partnership within the meaning of Section 1.752-3(a)(3) of the Regulations, the Partners’ interests in Partnership profits are in proportion to their Percentage Interests.

(e) To the extent permitted by Section 1.704-2(h)(3) of the Regulations, the General Partner shall endeavor to treat distributions of Net Cash Flow as having been made from the proceeds of a Nonrecourse Liability or a Partner Nonrecourse Debt only to the extent that such distributions would cause or increase an Adjusted Capital Account Deficit for any Limited Partner.

Section 3.6 Tax Allocations: Code Section 704(c). In accordance with Section 704(c) of the Code and the Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the capital of the Partnership shall, solely for tax purposes, be allocated among the Partners so as to take account of any variation between the adjusted basis of such property to the Partnership for federal income tax purposes and its initial Gross Asset Value (computed in accordance with subparagraph (i) of the definition of “Gross Asset Value” in Section 1.9). In the event the Gross Asset Value of any Partnership asset is adjusted pursuant to subparagraph (ii) of the definition of “Gross Asset Value” in Section 1.9, subsequent allocations of income, gain, loss, and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in the same manner as under Section 704(c) of the Code and the Regulations thereunder. Any elections or other decisions relating to such allocations shall be made by the General Partner in any manner that reasonably reflects the purpose and intention of this Agreement, provided that the Partnership shall elect to apply the traditional allocation method permitted by the Regulations under Section 704(c) of the Code. Allocations pursuant to this Section 3.6 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Partner’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any other provision of this Agreement. Except as otherwise provided in this Agreement, all items of Partnership income, gain, loss, deduction, and any other allocations not otherwise provided for shall be divided among the Partners in the same proportions as they share Profits or Losses, as the case may be, for the Allocation Year.

(a) No later than the end of the first Fiscal Quarter of each Fiscal Year of the Partnership, the General Partner will: (i) prepare in accordance with GAAP a statement of cash

flows for the immediately preceding Fiscal Year; and (ii) subject to Section 17-607 of the Act, cause the Partnership to pay cash distributions, in the aggregate amount of the Free Cash Flow, to the Partners, pro rata in accordance with their respective Percentage Interests; provided, however, that the General Partner will cause the Partnership to retain or withhold such cash as is necessary to fund any capital expenditures included in the Budget for the next succeeding Fiscal Year.

(b) Within 30 days following the Put Closing Date, the General Partner will: (i) prepare in accordance with GAAP a statement of cash flows for the Fiscal Year-to-date period through the most recently completed month-end preceding the date of the Put Notice (the “Put Measurement Period”); and (ii) subject to Section 17-607 of the Act, cause the Partnership to pay final cash distributions, to the Partners pro rata in accordance with their respective Percentage Interests, in the aggregate amount of Free Cash Flow for the Put Measurement Period. In no event will the MCI Partners receive any payment pursuant to this Section 4.1(b) which reflects a distribution already paid pursuant to Section 4.1(a).

(a) No later than the end of the first Fiscal Quarter of each Fiscal Year of the Partnership, the General Partner or its Affiliates will pay to the Partnership the interest income earned by HMA on the Partnership’s Free Cash Flow for the immediately preceding Fiscal Year (the “Annual Measurement Period”). Such payment will be in an amount equal to the product of:

(b) Within 30 days following the Put Closing Date, the General Partner will pay to the MCI Partner its pro rata share (based on the Percentage Interest of the MCI Partner) of the interest income earned by HMA on the Partnership’s Free Cash Flow for the Put Measurement Period. Such payment will be in the amount that results from application of the formula provided by Section 4.2(a), except that in such formula, the term “Put Measurement Period” will be substituted for the term “Annual Measurement Period”. In no event will the MCI Partner receive any payment pursuant to this Section 4.2(b) which reflects interest income already paid pursuant to Section 4.2(a).

Section 4.3Amounts Withheld. The General Partner is authorized to withhold from distributions, or with respect to allocations, to the Partners and to pay over to any federal, state, local or foreign government any amounts required to be so withheld pursuant to the Code or any provisions of any other federal, state, local or foreign law, and shall allocate any such amounts to the Partners with respect to which such amount was withheld. All amounts withheld or required to be withheld pursuant to the Code or any provision of any state, local or foreign tax law with respect to any payment, distribution, or allocation to the Partnership or the Partners and treated by the Code (whether or not withheld pursuant to the Code) or any such tax law as amounts payable by or in respect of any Partner or any Person owning an interest, directly or indirectly, in such Partner shall be treated as amounts distributed to the Partner with respect to which such amount was withheld pursuant to this Article 4 for all purposes under this Agreement.

Section 5.1 Authority of the General Partner. Subject to the limitations and restrictions set forth in this Agreement including, without limitation, those set forth in this, Article 5 the General Partner shall direct the business and affairs of the Partnership and in so doing shall manage, control and have all of the rights and powers which may be possessed by a general partner under the Act.

(l) the Partnership’s entering into any business other than the provision of acute care hospital services and ancillary services incidental thereto; or

(m) cause the Partnership to (A) fail to be taxed as a partnership for federal income tax purposes, including causing the Partnership to file an election with the Internal Revenue Service on Form 8832, or any successor form thereto, electing pursuant to Section 301.7701-3 of the Regulations to have the Partnership treated as an association taxable as a corporation for federal income tax purposes; or (B) take a position inconsistent with such treatment, except as required by law.

(a) The General Partner shall cause the Partnership to conduct its business and operations separate and apart from that of the General Partner, including, without limitation, (i) maintaining books and financial records of the Partnership separate from the books and financial records of the General Partner and observing all Partnership procedures and formalities, including, without limitation, maintaining minutes of Partnership meetings and acting on behalf of the Partnership only pursuant to due authorization of the Partners, (ii) causing the Partnership to pay its liabilities from assets of the Partnership, and (iii) causing the Partnership to conduct its dealings with third parties in its own name and as a separate and independent entity.

(b) The General Partner shall take all actions which may be necessary or appropriate (i) for the continuation of the Partnership’s valid existence as a limited partnership and its qualification to do business under the laws of the State of Texas and of each other

jurisdiction in which such existence or qualification is necessary to protect the limited liability of the Limited Partners or to enable the Partnership to conduct the business in which it is engaged or to perform its obligations or exercise its rights under any agreement to which it is a party and (ii) for the accomplishment of the Partnership’s purposes, including the acquisition, management, development, maintenance, preservation, and operation of Partnership Property in accordance with the provisions of this Agreement and applicable laws and regulations.

(a) Each Partner hereby makes, constitutes, and appoints each General Partner, each successor General Partner, and the Liquidator, severally, with full power of substitution and resubstitution, its true and lawful attorney-in-fact for it and in its name, place, and stead and for its use and benefit, to sign, execute, certify, acknowledge, swear to, file, publish and record (i) all certificates of limited partnership, amended name or similar certificates, and other certificates and instruments (including counterparts of this Agreement) which the General Partner or Liquidator may deem necessary to be filed by the Partnership under the laws of the State of Delaware or any other state or jurisdiction in which the Partnership is doing or intends to do business; (ii) any and all amendments, restatements or changes to this Agreement and the instruments described in Section 5.5(a)(i), as now or hereafter amended, which the General Partner may deem necessary to effect a change or modification of the Partnership approved by the Partners in accordance with the terms of this Agreement, including, without limitation, amendments or changes to reflect (1) the exercise by the General Partner of any power granted to it under this Agreement; (2) any amendments adopted by the Partners in accordance with the terms of this Agreement; (3) the admission of any substituted Partner; and (iv) the disposition by any Partner of its Interest; and (iii) all certificates of cancellation and other instruments which the General Partner or Liquidator may deem necessary to effect the dissolution and termination of the Partnership pursuant to the terms of this Agreement; and (d) any other instrument which is now or may hereafter be required by law to be filed on behalf of the Partnership or is deemed necessary by the General Partner or Liquidator to carry out fully the provisions of this Agreement in accordance with its terms.

The Limited Partners shall not have any right or power to take part in the management or control of the Partnership or its business and affairs or to act for or bind the Partnership in any way. Notwithstanding the foregoing, the Limited Partners shall have all of the rights and powers specifically set forth in this Agreement. A Limited Partner, any Affiliate thereof or an employee, stockholder, agent, director or officer of a Limited Partner or any Affiliate thereof, may also be an employee or agent of the Partnership or a stockholder, director or officer of a General Partner.

(f) All indemnities provided for in this Agreement shall survive the transfer of an Interest.

(a) In the event any claim is made by a third party against a Partner or Liquidator or any officer or successor or assign of any of them (each of them being referred to as an “Indemnitee”), with respect to an actual or potential liability for which any such Person is otherwise entitled to be indemnified under any provisions of this Article 6 and any such Person wishes to be indemnified with respect thereto, such Person shall promptly notify the Partnership, its receiver or trustee (the “Indemnitor”); provided that the failure of any such Person to notify any Indemnitor shall not relieve such Indemnitor from any liability which it otherwise may have to such Person hereunder.

(b) Each Indemnitee may by notice to the Indemnitor take control of all aspects of the investigation and defense of all claims asserted against it and may employ counsel of its choice and at the expense of the Indemnitor; provided that (A) the amount of any settlement such Indemnitee may enter into must be consented to by the Indemnitor and no Indemnitee may in connection with any such investigation, defense or settlement, without the consent of the Indemnitor, require the Indemnitor or any of its subsidiaries to take or refrain from taking any action (other than payment of such a settlement amount) or to make any public statement, which such Person reasonably considers to materially adversely affect its interest, and (B) such Indemnitee may not take control of any investigation, defense or settlement which could entail a risk of criminal liability to the Indemnitor or any of its subsidiaries. Upon the request of the Indemnitor, each Indemnitee shall use its best efforts to keep the Indemnitor reasonably apprised of the status of those aspects of such investigation and defense controlled by such Indemnitee and shall provide such information with respect thereto as the Indemnitor may reasonably request. The Indemnitor shall cooperate with the Indemnitee in all reasonable respects with respect thereto.

(c) Any Indemnitor may, by notice to the Indemnitees, take control of all aspects of the investigation and defense of all claims asserted against it, and may employ counsel of its choice and at its expense; provided that (A) no Indemnitor may without the consent of any Indemnitee agree to any settlement that requires such Indemnitee to make any payment that is not indemnified hereunder, or does not grant a general release to such Indemnitee, and in any event such Indemnitor may not in connection with any such investigation, defense or settlement, without the consent of any Indemnitee, take or refrain from taking any action which would reasonably be expected to materially impair the indemnification of such Indemnitee hereunder or would require such Indemnitee to take or refrain from taking any action or to make any public statement, which such Person reasonably considers to materially adversely affect its interests, (B) no Indemnitor may take control of any investigation, defense or settlement, without the consent of any Indemnitee, if the liabilities involved in such proceedings involve any material risk of the sale, forfeiture or loss of, or the creation of any Lien on, any property of such Indemnitee and (C) no Indemnitor may take control of any investigation, defense or settlement which could entail a risk of criminal liability to any Indemnitee. Upon the request of any Indemnitee, the Indemnitor shall use its best efforts to keep such Indemnitee reasonably apprised of the status of those aspects of such investigation and defense controlled by such Indemnitor and shall provide such information with respect thereto as such Indemnitee may reasonably request. The Indemnitees shall cooperate with the Indemnitor in all reasonable respects with respect thereto.

(a) Compensation and Reimbursement. Except as otherwise provided in this Agreement, no Partner shall receive any salary, fee, or draw for services rendered to or on behalf of the Partnership or otherwise in its capacity as a Partner, nor shall any Partner be reimbursed for any expenses incurred by such Partner on behalf of the Partnership or otherwise in its capacity as a Partner.

(b) Expenses. The General Partner may charge the Partnership, and shall be reimbursed, for any reasonable direct expenses incurred in connection with the Partnership’s business and payable to Persons other than the General Partner or any Affiliate of the General Partner.

The Partnership shall maintain at its principal place of business separate books of account for the Partnership which shall show a true, complete and accurate record of all costs and expenses incurred, all charges made, all credits made and received, and all income derived in connection with the conduct of the Partnership and the operation of its business in accordance with this Agreement.

(b) Accounting Method. The Partnership shall use the accrual method of accounting in preparation of its annual reports and for tax purposes and shall keep its books and records accordingly.

(c) Access to Books, Records, etc. The Partnership will afford to the officers and authorized representatives and agents of the MCI Partner reasonable access to and the right reasonably to inspect the Partnership and its premises, facilities and the books and records contemplated by Section 17-305(a) of the Act; provided, however, that: (i) such right of inspection will not extend to books and records and other information that pertain to Affiliates of HMA or the General Partner in which an MCI Partner has no equity interest; (ii) all agreements and covenants heretofore made by HMA or its Affiliates and MCI with respect to the protection of confidential information will continue in full force and effect with respect to confidential information of the Partnership, as if made by each MCI Partner; and (iii) the MCI Partner’s access to employees or other personnel of the Partnership will be limited to senior management personnel, and the MCI Partner will not contact any such personnel without first having coordinated such contact with the General Partner. The MCI Partner’s rights of access and inspection provided by this Section 7.l(c) will be made available at reasonable dates and times and in such a manner as not to interfere unreasonably with the operation of the Partnership. The rights granted to a Partner pursuant to this Section 7.1 (c) are expressly subject to compliance by such Partner with the confidentiality procedures and guidelines of the Partnership, as such procedures and guidelines may be established from time to time. The foregoing will not be

deemed or construed in any way to limit or restrict any rights or entitlements which the MCI Partner may have under applicable law to inspect, review and/or have access to the Partnership’s premises, facilities, books, records and employees.

(a) Preparation and Delivery. The General Partner shall be responsible for the preparation of financial reports of the Partnership and the coordination of financial matters of the Partnership with the Partnership’s accountants. Within 30 days following the end of each calendar month, the Partnership will deliver to the Limited Partners true and complete copies of the unaudited balance sheets and related unaudited statements of revenues and expenses of the Partnership for the month then ended, which will be certified by the chief financial officer of the Partnership as having been prepared in accordance with GAAP and as fairly presenting in all material respects the financial position and results of operations of the Partnership as of the date and for the period indicated.

(b) Audit Rights of MCI Partner. The MCI Partner will have the right, at its own cost and expense and within a reasonable time after the close of each Fiscal Year of the Partnership, to have the annual financial statements of the Partnership for that Fiscal Year reviewed or audited by such firm of independent accountants as the MCI Partner may determine. The MCI Partner will also have the right, at its own cost and expense, to have so reviewed or audited all accounting records pertaining to any provision of management services to the Partnership performed by an Affiliate of HMA or the General Partner. The General Partner will cooperate in all reasonable respects with the MCI Partner and its accounting firm(s) in providing access to the Partnership’s books and records for the purposes contemplated by this Section 7.2(b); provided, however, that: (i) such cooperation and access will be provided at reasonable dates and times and in such a manner as not to interfere unreasonably with the operation of the Partnership; and (ii) all out-of-pocket expenses incurred by the Partnership or the General Partner or its Affiliates in providing such cooperation and access will be promptly reimbursed by the MCI Partners upon verification of the amount thereof.

(a) The General Partner is authorized to make any and all elections for federal, state, and local tax purposes including, without limitation, any election, if permitted by applicable law: (i) to make the election provided for in Section 623l(a)(l)(B)(ii) of the Code or take any other action necessary to cause the provisions of Section 6221 through Section 6231 of the Code to apply to the Partnership, (ii) to adjust the basis of Partnership Property pursuant to Section 754, Section 734(b) and Section 743(b) of the Code, or comparable provisions of state or local law, in connection with Transfers of Partnership Interests and Partnership distributions; (iii) with the unanimous consent of the Limited Partners, to extend the statute of limitations for assessment of tax deficiencies against the Partners with respect to adjustments to the Partnership’s federal, state, or local tax returns; and (iv) to the extent provided in Section 6221 through Section 6231 of the Code, to represent the Partnership and the Partners before taxing authorities or courts of competent jurisdiction in tax matters affecting the Partnership or the Partners in their capacities as Partners, and to file any tax returns and execute any agreements or

other documents relating to or affecting such tax matters, including agreements or other documents that bind the Partners with respect to such tax matters or otherwise affect the rights of the Partnership and the Partners. The General Partner is specifically authorized to act as the “Tax Matters Partner” under the Code and in any similar capacity under state or local law.

(b) Upon the request of the MCI Partner or the Permitted Transferee thereof, the General Partner shall cause the Partnership to make the election under Section 754 of the Code.

(c) Necessary tax information shall be delivered to each Partner as soon as practicable after the end of each Fiscal Year of the Partnership but not later than four (4) months after the end of each Fiscal Year. The Tax Matters Partner shall file tax returns for the Partnership prepared in accordance with the Code and the Regulations.

Section 7.4 Proprietary Information. Notwithstanding anything to the contrary in this Article 7, the Limited Partners shall not have access to any information contemplated by Section 17-305(h) of the Act.

Section 8.1 Amendments. Amendments to this Agreement may be proposed by any Partner. Following such proposal, the General Partner shall submit to the Partners a verbatim statement of any proposed amendment, providing that counsel for the Partnership shall have approved of the same in writing as to form, and the General Partner shall include in any such submission a recommendation as to the proposed amendment. 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. Subject to Section 5.3, a proposed amendment shall be adopted and be effective as an amendment to this Agreement if it receives the affirmative vote of a majority of the Partners.

(a) Notice. Meetings of the Partners may be called by the General Partner and shall be called upon the written request of any Limited Partner. The call shall state the nature of the business to be transacted. Notice of any such meeting shall be given to all Partners not less than ten (10) or more than sixty (60) days prior to the date of such meeting. Partners may vote in person, by proxy or by telephone at such meeting. Whenever the vote or consent of Partners is permitted or required under this Agreement, such vote or consent may be given at a meeting of Partners or may be given in accordance with the procedure prescribed in Section 8.3. Except as otherwise expressly provided in this Agreement, the vote of a majority of the Partners shall control.

(b) Record Date. For the purpose of determining the Partners entitled to vote on, or to vote at, any meeting of the Partners or any adjournment thereof, the General Partner or the Partners requesting such meeting may fix, in advance, a date as the record date for any such determination. Such date shall not be more than sixty (60) days or less than ten (10) days before any such meeting.

(c) Quorum. At all meetings of the Partners, except as otherwise provided by law, there shall be present, in person or represented by proxy, Partners with at least a majority of the Interests entitled to vote thereat, in order to constitute a quorum; but if there be no quorum, the Partners present or represented may, by majority vote, adjourn the meeting from time to time, but not for a period of over thirty (30) days at any one time, without notice other than by announcement at the meeting, until a quorum shall attend. At any such adjourned meeting at which a quorum shall attend, any business may be transacted which might have been transacted at the meeting as originally called. When a quorum is once present, it is not broken by the subsequent withdrawal of any Partner.

(d) Proxies. Each Partner may authorize any Person or Persons to act for it by proxy on all matters in which the 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 Partner or its attorney-in-fact. No proxy shall be valid after the expiration of eleven (11) months from the date thereof unless otherwise provided in the proxy. Every proxy shall be revocable at the pleasure of the Partner executing it.

(e) Presiding Partner or Person. Each meeting of 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.

Section 8.3 Written Consent. Subject to Section 5.3, notwithstanding anything to the contrary in this Agreement any action that is required to be taken by action of the Partners may be taken without a meeting, without prior notice and without a vote, if a consent or consents, in writing, setting forth the action so taken, shall be signed by a sufficient number of Partners having at least the minimum number of Interests necessary to authorize such action at a duly called meeting with all Partners present. The General Partner shall deliver a copy of any action so taken by less than unanimous written consent to all Partners promptly after the taking of such action. Notwithstanding the foregoing or anything else contained in this Agreement, any consent of the MCI Partner or MCI Partner Designee may be given orally.

Section 9.1 Restriction on Transfers. No MCI Partner will Transfer any Interest now or hereafter owned by it except for the following Transfers to the following Persons (each, a “Permitted Transferee”), and only after compliance with the provisions of Section 9.2:

(a) any Transfer to any other Person with the prior written consent of the General Partner; or

(b) any Transfer to any Person which is, both immediately before and immediately after such Transfer, an Affiliate directly or indirectly wholly-owned by MCI; or

(c) any Transfer to any Person in full compliance with the provisions of Article 3 of the Put and First Refusal Agreement.

The parties agree that they will not cause or permit the Transfer on the books of the Partnership of any Interests now or hereafter owned by any MCI Partner unless the Transfer is made as permitted by this Section 9.1 and after compliance with Section 9.2. Any Permitted Transferee who satisfies the conditions of Section 9.2 shall be deemed admitted as a Limited Partner for all purposes of this Agreement and the Act. If a Permitted Transferee does not satisfy the conditions of Section 9.2 such Transfer shall be deemed null and void and of no force an effect with respect to all rights associated with such Interest.

Section 9.2 Agreement of Certain Transferees. Notwithstanding any other provision of this Agreement to the contrary, no Transfer of any Interest of an MCI Partner to a Permitted Transferee or a transfer by a HMA Partner will be effective unless each such Permitted Transferee or transferee of a HMA Partner, as a precondition to the Transfer, satisfies the following conditions:

(a) The Permitted Transferee or transferee of a HMA Partner becomes a party to this Agreement by dating and executing a copy of this Agreement and delivering it to the General Partner. In such event, such Permitted Transferee or transferee of a HMA Partner will be bound, as of the date of such execution and delivery, by all of the terms and conditions hereof as they apply to the Partner who transferred such Interest.

(b) The Permitted Transferee or transferee of a HMA Partner provides the Partnership with its taxpayer identification number, sufficient information to determine the transferee’s initial tax basis in the Interest Transferred, and any other information reasonably necessary to permit the Partnership to file all required federal and state tax returns and other legally required information statements or returns. Without limiting the generality of the foregoing, the Partnership shall not be required to make any distribution otherwise provided for in this Agreement with respect to any transferred Interest until it has received such information.

(a) In General. A Person who acquires an Interest but who is not admitted as a substituted Partner pursuant to Section 9.3(b) or (c), as appropriate, shall be entitled only to allocations and distributions with respect to such Interest in accordance with this Agreement, and shall have no right to any information or accounting of the affairs of the Partnership, shall not be entitled to inspect the books or records of the Partnership, and shall not have any of the rights of a General Partner or a Limited Partner under the Act or this Agreement.

(b) General Partner. A transferee who acquires an Interest from a General Partner hereunder by means of a Transfer but who is not admitted as a General Partner, shall have no authority to act for or bind the Partnership, to inspect the Partnership’s books, or

otherwise to be treated as a General Partner. Following such a Transfer, the transferor shall not cease to be a general partner of the Partnership and shall continue to be a General Partner until: (i) such transferee is admitted as a General Partner by the vote of the Limited Partners under Section 10.3; and (ii) such transferee becomes a party to this Agreement by dating and executing a copy of this Agreement in accordance with Section 9.2.

(c) Limited Partners. If a Limited Partner, other than one subject to the restrictions of Section 9.1, Transfers an Interest to a transferee, the Limited partner transferring such Interest shall not cease to be a Limited Partner of the Partnership and shall continue to be a Limited Partner until such time as the transferee is admitted as a Limited Partner. Such a transferee shall be deemed admitted as a Limited Partner upon: (i) the written consent of the General Partner and (2) the compliance with such transferee of the requirements of Section 9.2.

(d) Timing of Admission of New Partners. If the transferee of an Interest from a Partner is admitted as a Partner under this Agreement, such transferee shall be deemed admitted to the Partnership as a substituted Partner immediately prior to the Transfer, and such transferee shall continue the business of the Partnership without dissolution.

Section 9.4 Representations; Legend. Each Partner hereby agrees that the following legend may be placed upon any counterpart of this Agreement, the Certificate, or any other document or instrument evidencing ownership of Interests:

“Transfer of the Interests represented is restricted by the terms of a certain Agreement of Limited Partnership, dated May 1, 2002 among the Lone Star HMA, L.P. and its Partners, a copy of which is on file at the office of the Partnership.”

Section 9.5 Distributions and Allocations in Respect of Transferred Interests. If any Interest is Transferred during any Fiscal Year in compliance with the provisions of this Article 9, Profits, Losses, each item thereof, and all other items attributable to the Transferred Interest for such Fiscal Year shall be divided and allocated between the transferor and the transferee by taking into account their varying Percentage Interests during the Fiscal Year in accordance with Section 706(d) of the Code, using any conventions permitted by law and selected by the General Partner. All distributions on or before the date of such Transfer shall be made to the transferor, and all distributions thereafter shall be made to the transferee. Solely for purposes of making such allocations and distributions, the Partnership shall recognize such Transfer not later than the end of the calendar month during which it is given notice of such Transfer, provided that, if the Partnership is given notice of a Transfer at least twenty (20) days prior to the Transfer, the Partnership shall recognize such Transfer as of the date of such Transfer, and provided further that if the Partnership does not receive a notice stating the date such Interest was Transferred and such other information as the General Partner may reasonably require within thirty (30) days after the end of the Fiscal Year during which the Transfer occurs, then all such items shall be allocated, and all distributions shall be made, to the Person who, according to the books and records of the Partnership, was the owner of the Interest on the last day of such Fiscal Year. Neither the Partnership nor any General Partner shall incur any liability for making allocations and distributions in accordance with the provisions of this Section 9.5, whether or not any General Partner or the Partnership has knowledge of any Transfer of ownership of any Interest.

Section 10.1 Covenant Not to Withdraw, Transfer, or Dissolve. Except as otherwise permitted by this Agreement, the General Partner hereby covenants and agrees not to (a) take any action to file a certificate of dissolution or its equivalent with respect to itself, (b) withdraw or attempt to withdraw from the Partnership, (c) exercise any power under the Act to dissolve the Partnership, (d) Transfer all or any portion of its Interest as a General Partner, or (f) petition for judicial dissolution of the Partnership. Further, the General Partner hereby covenants and agrees to continue to carry out the duties of a General Partner hereunder until the Partnership is dissolved and liquidated pursuant to Article 11.

(a) The General Partner shall cease to be a General Partner upon the first to occur of (i) the bankruptcy of the General Partner; (ii) the Transfer of the General Partner’s entire Interest as a General Partner, provided that the transferee is admitted as a substituted General Partner pursuant to Section 9.3(a); (iii) the involuntary Transfer by operation of law of such General Partner’s entire Interest in the Partnership, provided that the transferee is admitted as a substituted General Partner pursuant to Section 9.3(a) (iv) the vote of a majority of the Limited Partners to approve a request by such General Partner to retire, or (v) the vote of a majority of the Limited Partners to remove such General Partner after such General Partner has committed any act or suffered any other condition that would justify a decree of dissolution of the Partnership under the laws of the State of Delaware. In the event a Person ceases to be a General Partner without having Transferred its entire Interest as a General Partner, such Person shall be treated as an unadmitted transferee of an Interest as a result of a Transfer. If a Person ceases to be a General Partner for any reason under this Agreement, such Person shall continue to be liable as a General Partner for all debts and obligations of the Partnership existing at the time such Person ceases to be a General Partner, regardless of whether, at such time, such debts or liabilities were known or unknown, actual or contingent. A Person shall not be liable as a General Partner for Partnership debts and obligations arising after such Person ceases to be a General Partner. Any debts, obligations, or liabilities in damages to the Partnership of any Person who ceases to be a General Partner shall be collectible by any legal means and the Partnership is authorized, in addition to any other remedies at law or in equity, to apply any amounts otherwise distributable or payable by the Partnership to such Person to satisfy such debts, obligations, or liabilities.

(b) If at the time a Person ceases to be a General Partner such Person is also a Limited Partner with respect to an Interest other than its Interest as a General Partner, such cessation shall not affect such Person’s rights and obligations with respect to such Interest.

Section 10.3 Election of New General Partners. Provided the Partnership has one General Partner, any Partner may nominate one or more Persons for election as additional General Partners. The election of an additional General Partner shall require an affirmative vote of a majority in interest of the Limited Partners. If there is only one General Partner and the status of such General Partner terminates for any reason under Section 10.2, the HMA Partners and the MCI Partner agree to vote their Interests to elect the successor General Partner nominated by the HMA Partners, so as to avoid the occurrence of a Liquidating Event; provided, however, that if the HMA Partners fail to nominate and to vote their Interests in favor of the successor General Partner within twenty days after any termination contemplated by Section 10.2 and such failure is not remedied within twenty (20) days after the HMA Partners receive written notice from the MCI Partner of such failure, then the MCI Partner shall have the right to appoint such successor General Partner upon the expiration of such 20-day period.

Section 11.1 Liquidating Events. The Partnership shall dissolve and commence winding up and liquidating upon the first to occur of any of the following (each a “Liquidating Event”):

(b) The unanimous vote of the Partners to dissolve, wind up, and liquidate the Partnership;

(c) The happening of any other event that makes it unlawful, impossible, or impractical to carry on the business of the Partnership; or

(d) The withdrawal or removal of the General Partner, the assignment by the General Partner of its entire Interest, or any other event that causes the General Partner to cease to be a general partner under the Act, provided that any such event shall not constitute a Liquidating Event if the Partnership is continued pursuant to this Section 11.1.

The Partners hereby agree that, notwithstanding any provision of the Act, the Partnership shall not dissolve prior to the occurrence of a Liquidating Event. Upon the occurrence of any event set forth in Section 11.l(d) (so long as no other Liquidating Event has occurred), the Partnership shall not be dissolved or required to be wound up if (x) at the time of such event there is at least one remaining General Partner and that General Partner carries on the business of the Partnership (any such remaining General Partner being hereby authorized to carry on the business of the Partnership), or (y) within ninety (90) days after such event all remaining Partners agree in writing to continue the business of the Partnership and to the appointment, effective as of the date of such event, of one or more additional General Partners. If it is determined, by a court of competent jurisdiction, that the Partnership has dissolved prior to the occurrence of a Liquidating Event, or if upon the occurrence of an event specified in Section 11.1(d), the Partners fail to appoint a substitute General Partner effective as of such event and to agree to continue the

business of the Partnership as provided in this Section 11.1, then within an additional ninety (90) days after such determination or the last day of such ninety (90) day period, as the case may be (the “Reconstitution Period”), a two-thirds majority of the Partners may elect to reconstitute the Partnership and continue its business on the same terms and conditions set forth in this Agreement by forming a new limited partnership on terms identical to those set forth in this Agreement and having as a general partner a Person elected by such two-thirds majority. Upon any such election by a two-thirds majority of the Partners, all Partners shall be bound thereby and shall be deemed to have consented thereto. Unless such an election is made within the Reconstitution Period, the Partnership shall wind up its affairs in accordance with Section 11.2. If such an election is made within the Reconstitution Period, then:

(i) The reconstituted limited partnership shall continue until the occurrence of a Liquidating Event as provided in this Section 11.1;

(ii) If the successor general partner is not a former General Partner, then the Interest of any former General Partner shall be treated thenceforth as the Interest of a Limited Partner; and

(iii) All necessary steps shall be taken to cancel this Agreement and the Certificate and to enter into a new partnership agreement and certificate of limited partnership, and the successor general partner may for this purpose exercise the powers of attorney granted the General Partner pursuant to Section 5.5 and shall cause such certificate of limited partnership for the reconstituted partnership to be filed in the office of the Secretary of State of Delaware in accordance with the Act;

provided that the right of a two-thirds majority of the Partners to select a successor general partner and to reconstitute and continue the business of the Partnership shall not exist and may not be exercised unless the Partnership has received an opinion of counsel that the exercise of the right would not result in the loss of limited liability of any Limited Partner and neither the Partnership nor the reconstituted partnership would cease to be treated as a partnership for federal income tax purposes upon the exercise of such right to continue.

Section 11.2 Winding Up. 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 and 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. To the extent not inconsistent with the foregoing, all covenants contained in this Agreement and obligations provided for in this Agreement shall continue to be fully binding on the Partners until such time as the Partnership Property has been distributed pursuant to this Section 11.2 and the Certificate has been canceled in accordance with the Act. The Liquidator shall be responsible for overseeing the winding up and dissolution of the Partnership, shall take full account of the Partnership’s liabilities and property, shall cause the Partnership Property to be liquidated as promptly as is consistent with obtaining the fair value thereof unless the Partners unanimously consent to distributions of all or any part of the Partnership Property in kind, and shall cause the Partnership Property or the proceeds therefrom, to the extent sufficient therefor, to be applied and distributed in the following order:

(a) First, to creditors other than the General Partner in satisfaction of all of the Partnership’s debts and liabilities other than liabilities for which reasonable provision for payment has been made and liabilities for distributors under Section 17-606 of the Act;

(b) Second, to the payment and discharge of all of the Partnership’s debts and liabilities to the General Partner to the extent adequate provision therefore has not been made; and

(c) The balance, if any, to the Partners in accordance with their positive Capital Accounts, after giving effect to all contributions, distributions, and allocations for all periods.

The General Partner shall not receive any additional compensation for any services performed pursuant to this Article 11. The General Partner understands and agrees that by accepting the provisions of this Section 11.2 setting forth the priority of the distribution of the assets of the Partnership to be made upon its liquidation, the General Partner expressly waives any right which it, as a creditor of the Partnership, might otherwise have under the Act to receive distributions of assets pari passu with the other creditors of the Partnership in connection with a distribution of assets of the Partnership in satisfaction of any liability of the Partnership, and hereby subordinates to said creditors any such right.

Section 11.3 Limitations on Distributions. In the discretion of the Liquidator, a pro rata portion of the distributions that would otherwise be made to the Partners pursuant to this Article 11 may be:

(a) Distributed to a trust established for the benefit of the Partners solely for the purposes of liquidating Partnership Property, collecting amounts owed to the Partnership, and paying any contingent or unforeseen liabilities or obligations of the Partnership or of the General Partner arising out of or in connection with the Partnership. The assets of any such trust shall be distributed to the 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 Partners pursuant to Section 11.2; or

(b) Withheld to provide a reasonable reserve for Partnership liabilities (contingent or otherwise) and to allow for the collection of the unrealized portion of any installment obligations owed to the Partnership, provided that such withheld amounts shall be distributed to the Partners as soon as practicable.

The portion of the distributions that would otherwise have been made to each of the Partners that is instead distributed to a trust pursuant to Section 11.3(a) or withheld to provide a reserve pursuant to Section 11.3(b) shall be determined in the same manner as the expense or deduction would have been allocated if the Partnership had realized an expense equal to such amounts immediately prior to distributions being made pursuant to Section 11.2.

Section 11.4 Compliance With Certain Requirements of Regulations; Deficit Capital Accounts. In the event the Partnership is “liquidated” within the meaning of Section 1.704- l(b)(2)(ii)(g) of the Regulations, (x) distributions shall be made pursuant to this Article 11 to the Partners who have positive Capital Accounts in compliance with Section 1.704-l(b)(2)(ii)(b)(2) of the Regulations, and (y) if any General Partner’s Capital Account has a deficit balance (after giving effect to all contributions, distributions, and allocations for all taxable years, including the taxable year during which such liquidation occurs), such General Partner shall contribute to the capital of the Partnership the amount necessary to restore such deficit balance to zero in compliance with Section 1.704-1(b)(2)(ii)(b)(3) of the Regulations. If any Limited Partner has a deficit balance in its Capital Account (after giving effect to all contributions, distributions, and allocations for all taxable years, including the taxable year during which such liquidation occurs), such Limited Partner shall have no obligation to make any contribution to the capital of the Partnership with respect to such deficit, and such deficit shall not be considered a debt owed to the Partnership or to any other Person for any purpose whatsoever. In the discretion of the Liquidator, a pro rata portion of the distributions that would otherwise be made to the Partners pursuant to this Article 11 may be:

Section 11.5 Deemed Contribution and Distribution. In the event the Partnership is liquidated within the meaning of Section 1.704-1 (b)(2)(ii)(g) of the Regulations but no Liquidating Event has occurred, the Partnership 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, solely for federal income tax purposes, the Partnership shall be deemed to have contributed all Partnership Property and liabilities to a new limited partnership in exchange for an interest in such new limited partnership and, immediately thereafter, the Partnership will be deemed to liquidate by distributing interests in the new limited partnership to the Partners.

Section 11.6 Rights of Partners. Each Partner shall look solely to the assets of the Partnership for the return of its Capital Contribution and shall have no right or power to demand or receive property other than cash from the Partnership, and no Partner shall have priority over any other Partner as to the return of its Capital Contributions or distributions.

Section 11.7 Notice of Dissolution. In the event a Liquidating Event occurs or an event occurs that would, but for provisions of Section 11.1, result in a dissolution of the Partnership, the General Partner shall, within thirty (30) days thereafter, provide written notice thereof to each of the Partners and to all other parties with whom the Partnership regularly conducts business (as determined in the discretion of the General Partner) and shall publish notice thereof in a newspaper of general circulation in each place in which the Partnership regularly conducts business (as determined in the discretion of the General Partner).

Section 11.8 Character of Liquidating Distributions. All payments made in liquidation of the Interest of a retiring Partner pursuant to Article 11 shall be made in exchange for the interest of such Partner in Partnership Property pursuant to Section 736(b)(1) of the Code, including the interest of such Partner in Partnership goodwill.

(a) Definition. The “Liquidator” shall mean the General Partner; provided that either (i) if a Bankruptcy has occurred with respect to the General Partner, or (ii) if there is no remaining General Partner, then a “Liquidator” shall be appointed by the Limited Partners, which Person may be the General Partner.

(b) Fees. In the event that the Liquidator is other than a General Partner, the Partnership is authorized to pay a reasonable fee to the Liquidator for its services performed pursuant to this Article 11 and to reimburse the Liquidator for its reasonable costs and expenses incurred in performing those services.

(c) Indemnification. In the event that the Liquidator is a Person other than a General Partner, the Partnership, or in the event that the Partnership has terminated, the General Partner, shall indemnify, save harmless, and pay all judgments and claims against, such Liquidator or any officers, directors, agents or employees of the Liquidator relating to any liability or damage incurred by reason of any act performed or omitted to be performed by the Liquidator, officer, director, agents or employees in connection with the liquidation of the Partnership, including reasonable attorneys’ fees incurred by the Liquidator, officer, director, agent or employee in connection with the defense of any action based on any such act or omission, which attorneys’ fees may be paid as incurred, except to the extent such liability or damage is caused by the gross negligence, fraud, or willful misconduct of the Liquidator or any partners, officers, directors, agents or employees of the Liquidator.

Section 12.1 Restrictive Covenant. The parties hereby acknowledge that the HMAPartners and their Affiliates are subject to and bound by the terms of a certain restrictive covenant contained in Section 10.3 of a certain Partnership Interest Purchase Agreement, dated February 25, 2002, by and among, Health Management Associates, Inc., Manor Care, Inc. and the Partners..

Section 13.1 Generally. The Partnership will not authorize, issue, offer or sell, or cause to be authorized, issued, offered or sold, any Interests unless the Partnership has first offered such Interests to the MCI Partner in accordance with the procedure provided by Section 13.l(a).

(a) Prior to the authorization, issuance, offer or sale of any Interests (each, an “Offering”), the Partnership will offer to the MCI Partner such additional amount of Interests as will enable the MCI Partner to maintain the same Percentage Interest immediately after consummation of the Offering as the MCI Partner had immediately prior to consummation of the Offering (the “MCI Pro Rata Share”). For a 60-day period after the Partnership gives written notice to the MCI Partner of the terms and conditions of any Offering, the MCI Partner will be entitled to subscribe for the MCI Pro Rata Share of the Interests being offered, on the same terms and conditions (including price and payment terms) as pertain to the Offering. If the MCI Partner fails to subscribe for the MCI Pro Rata Share of the offered Interests within such 60-day period, or if the MCI Partner subscribes therefor but fails to consummate the purchase of the MCI Pro Rata Share in accordance with the terms and conditions that pertain to the Offering, then the MCI Partner will have no further rights whatsoever with respect to the Interests subject to the Offering.

(b) The amount paid by the MCI Partner to purchase the MCI Pro Rata Share of the offered Interests will be a Capital Contribution of the MCI Partner, and after payment thereof, the parties’ respective Percentage Interests will be recalculated to reflect the same.

Section 14.1 Guaranty of Parent Entities. HMA hereby ensures and guarantees to the MCI Partner the full and timely performance by the HMA Partners of all of their duties, responsibilities and obligations under and pursuant to this Agreement. MCI hereby ensures and guarantees to the HMA Partners the full and timely performance by the MCI Partner of all of its duties, responsibilities and obligations under and pursuant to this Agreement. Nothing contained in this Section 14.1 will be construed as giving rise to any rights to or in any third-party against HMA or MCI, including, but not limited to any creditors of the Partnership.

Section 15.1 Notices. Any notice, payment, demand, or communication required or permitted to be given by any provision of this Agreement shall be in writing or by facsimile and shall be deemed to have been delivered, given, and received for all purposes (i) if delivered personally, to the Person or to an officer of the Person to whom the same is directed or (ii) when the same is actually received, if sent by registered or certified mail or by overnight courier, postage and charges prepaid or by facsimile, if such facsimile is followed by a hard copy of the facsimilied communication sent by registered or certified mail or by overnight courier, charges prepaid, addressed as follows, or to such other address as such Person may from time to time specify by notice to the Partners:

(a) If to the Partnership, to the Partnership at the address set forth in Section 1.4;

Any Person may from time to time specify a different address by notice to the Partnership and the Partners.

Section 15.2 Effect. This Agreement, together with the Put and First Refusal Agreement, supersedes all prior agreements and constitutes the entire agreement of whatsoever kind or nature existing among the parties representing the within subject matter, and no party will be entitled to benefits other than those specified herein and therein. The parties specifically acknowledge that in entering into and executing this Agreement, the parties rely solely upon the representations and agreements contained herein and therein and no others. All prior representations or agreements, whether written or oral, are superseded unless and until made in writing and signed by the party sought to be charged therewith. This Agreement may be amended, and the terms hereof may be modified, only by a writing executed by MCI and HMA, and any matter referred to herein as mutually agreed to or designated by the parties must be evidenced by such a writing. Except as otherwise provided in this Agreement, every covenant, term, and provision of this Agreement shall be binding upon and inure to the benefit of the Partners and their respective successors, transferees, and assigns.

Section 15.3 Construction. Every covenant, term, and provision of this Agreement shall be construed simply according to its fair meaning and not strictly for or against any Partner. The terms of this Agreement are intended to embody the economic relationship among the Partners and shall not be subject to modification by, or be conformed with, any actions by the Internal Revenue Service except as this Agreement may be explicitly so amended and except as may relate specifically to the filing of tax returns.

Section 15.4 Headings. Section and other headings contained in this Agreement are for reference purposes only and are not intended to describe, interpret, define, or limit the scope, extent, or intent of this Agreement or any provision.

Section 15.5 Severability. Except as otherwise provided in the succeeding sentence, every provision of this Agreement is intended to be severable, and if any term or provision is illegal or invalid for any reason whatsoever, such illegality or invalidity shall not affect the validity or legality of the remainder of this Agreement. The preceding sentence of this Section 15.5 shall be of no force or effect if the consequence of enforcing the remainder of this Agreement without such illegal or invalid term or provision would be to cause any Partner to lose the benefit of its economic bargain.

Section 15.6 Incorporation by Reference. Every exhibit, schedule, and other appendix attached to this Agreement and referred to herein is not incorporated in this Agreement by reference unless this Agreement expressly otherwise provides.

Section 15.7 Further Action. Each Partner, upon the request of the General Partner, agrees to perform all further acts and execute, acknowledge, and deliver any documents which may be reasonably necessary, appropriate, or desirable to carry out the provisions of this Agreement.

Section 15.8 Variation of Pronouns. All pronouns and any variations thereof shall be deemed to refer to masculine, feminine, or neuter, singular or plural, as the identity of the Person or Persons may require.

(a) This Agreement will be governed by and construed in accordance with the laws of the State of Delaware without regard to its principles of conflicts of laws. The parties agree that, except as otherwise provided by Section 13.9(b), the sole and exclusive forum for any claim, demand, action, suit or proceeding related to this Agreement, the interpretation or construction hereof and the transactions contemplated hereby will be the Court of Chancery of and for the County of New Castle, State of Delaware. Each party unconditionally and irrevocably agrees not to bring any claim, demand, action, suit or proceeding in any other forum and not to plead or otherwise attempt to defeat the trial of such a matter in such court, whether by asserting that such court is an inconvenient forum, lacks jurisdiction (personal or other) or otherwise. EACH PARTY RECOGNIZES THAT IT IS NOT ENTITLED TO TRIAL BY JURY IN THE COURT OF CHANCERY.

(b) No party will resort to litigation against another party regarding a dispute arising out of this Agreement without first attempting to resolve the dispute by non-binding mediation. Any party may initiate a mediation proceeding by written request to all of the other parties. For a reasonable time thereafter, the parties will be obligated to engage in good faith in

mediation, which will be conducted in accordance with the Center for Public Resources Model Procedure for Mediation of Business Disputes. The expenses of such mediation will be borne by the non-prevailing party of such mediation or as otherwise determined in such mediation proceeding.

Section 15.10 Waiver of Action for Partition; No Bill For Partnership Accounting. Each Partner irrevocably waives any right that it may have to maintain any action for partition with respect to any of the Partnership Property. To the fullest extent permitted by law, each Partner covenants that it will not (except with the consent of the General Partner) file a bill for Partnership accounting.

Section 15.11 Enforcement Expenses. In the event any party elects to incur legal expenses in connection with any legal or equitable proceeding to enforce, defend or interpret any provision of this Agreement, as between it and any other party, the prevailing party will be entitled to recover from the other party such legal expenses, including reasonable attorney’s fees, costs and necessary disbursements, in addition to any other relief to which such party may be entitled.

Section 15.12 Counterpart Execution. This Agreement may be executed in any number of counterparts with the same effect as if all the Partners had signed the same document. All counterparts shall be construed together and shall constitute one agreement.

Section 15.13 Sole and Absolute Discretion. Except as otherwise provided in this Agreement, all actions which the General Partner may take and all determinations which the General Partner may make pursuant to this Agreement may be taken and made at the sole and absolute discretion of the General Partner.

Section 15.14 Specific Performance. Each Partner agrees with the other Partners that the other Partners would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with their specific terms and that monetary damages would not provide an adequate remedy in such event. Accordingly, it is agreed that, in addition to any other remedy to which the nonbreaching Partners may be entitled, at law or in equity, the nonbreaching Partners shall be entitled to injunctive relief to prevent breaches of the provisions of this Agreement and specifically to enforce the terms and provisions in any action instituted in any court of the United States or any state thereof having subject matter jurisdiction thereof.

Section 15.15 Waiver of Jury Trial. Each of the Partners irrevocably waives to the extent permitted by law all rights to trial by jury in any action, proceeding or counterclaim arising out of or relating to this Agreement.
