(a)Each Limited Partner and each Assignee who accepts Partnership Units (or any other Partnership Interest or any rights, benefits or privileges associated therewith) is deemed to irrevocably constitute and appoint the General Partner, any Liquidator and authorized officers and attorneys-in-fact of each, and each such Person acting singly, in each case with full power of substitution, as its true and lawful agent and attorney-in-fact, with full power and authority in its name, place and stead to:

(i)execute, swear to, acknowledge, deliver, file and record in the appropriate public offices:

(A)all certificates, documents and other instruments (including, without limitation, this Agreement and the Certificate and all amendments or restatements thereof) that the General Partner or the Liquidator deems appropriate or necessary to form, qualify or continue the existence or qualification of the Partnership as a limited partnership (or a partnership in which the Limited Partners have limited liability) in the State of Delaware and in all other jurisdictions in which the Partnership may or plans to conduct business or own property, including, without limitation, any documents necessary or advisable to convey any Contributed Property to the Partnership;

Nothing contained herein shall be construed as authorizing the General Partner or any Liquidator to amend this Agreement except in accordance with Section 14.1 hereof or as may be otherwise expressly provided for in this Agreement.

(b)The foregoing power of attorney is hereby declared to be irrevocable and a power coupled with an interest, in recognition of the fact that each of the Partners will be relying upon the power of the General Partner and any Liquidator to act as contemplated by this Agreement in any filing or other action by it on behalf of the Partnership, and it shall survive and not be affected by the subsequent Incapacity of any Limited Partner or Assignee and/or the Transfer of all or any portion of such Limited Partner’s or Assignee’s Partnership Units, except where all of a Limited Partner’s or Assignee’s Partnership Units are being Transferred and the Assignee thereof with the consent of the General Partner is admitted as a Substituted Limited Partner; provided, however, the power of attorney shall survive the delivery of such Transfer for the sole purpose of enabling any such attorney-in-fact to effect such substitution. This power of attorney does not supersede any part of this Agreement, nor is it to be used to deprive any Limited Partner of its rights hereunder. It is intended only to facilitate the execution of documents and the carrying out of other procedural or ministerial functions and shall extend to such Limited Partner’s or Assignee’s heirs, successors, assigns and personal representatives.

(c)Each such Limited Partner or Assignee hereby agrees to be bound by any representation made by the General Partner or any Liquidator, acting in good faith pursuant to such power of attorney, and each such Limited Partner or Assignee hereby waives any and all defenses which may be available to contest, negate or disaffirm the action of the General Partner or any Liquidator, taken in good faith under such power of attorney.

(d)Each Limited Partner or Assignee shall execute and deliver to the General Partner or the Liquidator, within fifteen (15) days after receipt of the General Partner’s or Liquidator’s request therefor, such further designation, powers of attorney and other instruments

as the General Partner or the Liquidator, as the case may be, deems necessary to effectuate this Agreement and the purposes of the Partnership.

2.7Effectiveness of this Agreement. This Agreement shall govern the operations of the Partnership and the rights and restrictions applicable to the Partners, to the extent permitted by law. Pursuant to Section 17-101(12) of the Act, all Persons who become holders of Partnership Interests shall be bound by the provisions of this Agreement. The execution by a Person of this Agreement and acceptance thereof by the General Partner in accordance with the terms of this Agreement or the receipt of Partnership Interests by a Person as a successor or assign of an existing Partner and the consent of the General Partner to the admission of such Person as a Substituted Limited Partner in accordance with the terms of this Agreement shall be deemed to constitute a request that the records of the Partnership reflect such admission, and shall be deemed to be a sufficient act to comply with the requirements of Section 17-101(12) of the Act and to so cause that Person to become a Partner as of the date of acceptance of its Capital Contribution by the Partnership and to bind that Person to the terms and conditions of this Agreement (and to entitle that Person to the rights of a Partner hereunder).

(f)to engage in such other ancillary activities as shall be necessary or desirable to effectuate the foregoing purposes; provided, however, that such business shall be limited to and conducted in such a manner as to permit AHR at all times to be classified as a REIT, unless AHR determines not to qualify as a REIT or ceases to qualify as a REIT for reasons other than the conduct of the business of the Partnership.

(c)Partnership Units. Each Partner shall own Partnership Units in the numbers and of the class set forth for such Partner in Exhibit A and shall have a Percentage Interest in the Partnership as set forth in Exhibit A, which Percentage Interest shall be adjusted in Exhibit A from time to time by the General Partner to the extent necessary to reflect accurately redemptions, additional Capital Contributions, the issuance of additional Partnership Units or similar events having an effect on the number of Partnership Units held by, and the Percentage

Interest of, any Partner. Except to the extent set forth in a written amendment to this Agreement adopted by the General Partner to establish a new class or series of Partnership Interest pursuant to Section 4.2 or 4.3 (a “Partnership Unit Designation”), each Partnership Unit shall entitle the holder thereof to one vote on all matters on which the Partners (or any portion of the Partners) are entitled to vote under this Agreement.

(b)Subject to the limitations set forth in Sections 4.2(a), 4.3(a) and 14.1, the General Partner may take such steps as it, in its sole and absolute discretion, deems necessary or appropriate to admit any Person as a Limited Partner of the Partnership in accordance with Section 12.2 or to issue any Partnership Interests, including, without limitation, amending the Certificate, Exhibit A or any other provision of this Agreement.

(c)Without limiting the foregoing, the General Partner is expressly authorized to cause the Partnership to issue Partnership Interests (or options to acquire Partnership Interests) for less than fair market value, so long as the General Partner concludes in good faith that such issuance is in the interest of the Partnership and the Partners (for example, and not by way of limitation, the issuance of Partnership Units in connection with a Stock Incentive Plan providing for employee purchases of REIT Stock and corresponding Partnership Units at a discount from fair market value or employee options that have an exercise price that is less than the fair market value of the REIT Stock and corresponding Partnership Units covered by the option, either at the time of issuance or at the time of exercise).

4.3Issuance of Securities by AHR.

(a)General. AHR shall not issue any debt securities, preferred stock, Common Stock, any other class of REIT Stock or rights, options, warrants or other securities convertible into or exchangeable for preferred stock, Common Stock or any other class of REIT Stock (collectively, “Securities”) (including pursuant to AHR’s distribution reinvestmet plan), other than (1) as payment of the REIT Stock Amount in connection with a redemption of Partnership Units pursuant to Section 8.6, (2) upon the conversion, exchange or exercise of other outstanding securities of AHR in accordance with the terms of such securities, or (3) to all holders of REIT Stock or all holders of a class of REIT Stock on a pro rata basis, unless AHR shall:

(i)in the case of REIT Stock or other equity Securities other than Securities described in Section 4.3(a)(ii) below, (A) contribute to the Partnership the proceeds of or consideration (including any property or other non-cash assets) received upon the issuance of such Securities, and (B) receive from the Partnership in consideration for such contributions Partnership Interests with the same terms and conditions, including dividend, dividend priority and liquidation preference, as are applicable to such Securities (including, for example, the Partnership issuing to AHR Partnership Class T Units in the case of any issuance of REIT Class T Stock by AHR and the Partnership issuing to AHR Partnership Class I Units in the case of any issuance of REIT Class I Stock by AHR);

(ii)in the case of options, warrants or other rights to purchase REIT Stock, or other equity securities convertible into or exchangeable for REIT Stock, (A) contribute to the Partnership the proceeds of or consideration (including any property or other non-cash assets) received upon the issuance of such options, warrants or other rights to purchase REIT Stock, or other equity Securities convertible into or exchangeable for REIT Stock, and (B) receive from the Partnership in consideration for such contributions a number of options, warrants or other rights to purchase Partnership Interests equal to the number of such Securities issued by AHR, with equivalent rights, preferences and limitations to the terms of such equity Securities; and

(iii)in the case of debt securities, lend to the Partnership the proceeds of or consideration received for such Securities on the same terms and conditions, including interest rate and repayment schedule, as shall be applicable with respect to or incurred in connection with the issuance of such Securities and the proceeds of, or consideration received from, any subsequent exercise, exchange or conversion thereof (if applicable).

(b)Splits. The Partnership shall (i) make a distribution in a class or series of Partnership Units to all Partners holding such class or series of Partnership Units on a pro rata basis in accordance with their respective Class Percentage Interests as of the date of such distribution, (ii) subdivide its outstanding Partnership Units of a particular class or series, or (iii) combine its outstanding Partnership Units of a class or series into a smaller number of Partnership Units, in the event AHR takes an analogous action with respect to the corresponding class or series of REIT Stock. The intent of the previous sentence is that one Partnership Unit remains the economic equivalent of one share of REIT Stock without dilution. If AHR determines that it is necessary or desirable to make any filings under the Act or otherwise in

order to reference the existence of such action, AHR may cause such filings to be made, which filings might take the form of amendments to the Certificate; provided, however, that, unless specifically required by this Agreement or the Act after giving effect to the terms of this Agreement, no approval or consent of any Partners shall be required in connection with the making of any such filing.

(c)Treatment of Proceeds. If the proceeds actually received by AHR in connection with an issuance of Securities by AHR are less than the gross proceeds of such offering, grant, award or issuance as a result of any underwriter’s discounts, commissions or other fees or expenses paid or incurred in connection with such offering, grant, award or issuance, then AHR shall be deemed to have made a Capital Contribution to the Partnership in the amount of the gross proceeds of such offering, grant, award or issuance, and the Partnership shall be deemed simultaneously to have paid pursuant to Section 7.3 for the amount of such expenses actually incurred and paid by AHR, with such expenses allocated to the applicable class or series of Partnership Units or other securities corresponding to the Securities issued by AHR.

4.4Additional Funds.

(a)The sums of money required to finance the business and affairs of the Partnership shall be derived from the Capital Contributions made to the Partnership by the Partners as set forth in Sections 4.1 and 4.3(a) and from funds generated from the operation and business of the Partnership.

(b)In the event additional financing is needed from sources other than as set forth in Section 4.4(a) for any reason, the General Partner may, in its sole and absolute discretion, in such amounts and at such times as it solely shall determine to be necessary or appropriate:

(i)cause the Partnership to issue additional Partnership Interests and admit additional Limited Partners to the Partnership in accordance with Section 4.2;

(ii)cause the Partnership to borrow money, enter into loan arrangements, issue debt securities, obtain letters of credit or otherwise borrow money on a secured or unsecured basis;

(iii)make a loan or loans to the Partnership (in accordance with Section 4.3(a)); or

(iv)cause the Partnership to sell any assets or properties directly or indirectly owned by the Partnership.

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

4.6No Interest. No Partner shall be entitled to interest on any Capital Contribution or on such Partner’s Capital Account.

4.7No Preemptive Rights. Subject to Section 4.2 and any preemptive rights that may be granted in connection with the issuance of Partnership Interests under Section 4.3(a), no Person shall have any preemptive or other similar right with respect to any:

(a)additional Capital Contributions or loans to the Partnership; or

(b)issuance or sale of any Partnership Units or other Partnership Interests.

4.8Capital Accounts. The Partnership shall establish and maintain throughout the life of the Partnership for each Partner a separate “Capital Account” in accordance with Treasury Regulations Section 1.704-1(b)(2)(iv). If (i) a new or existing Partner acquires an additional Partnership Interest in exchange for more than a de minimis Capital Contribution, (ii) the Partnership distributes to a Partner more than a de minimis amount of Partnership property as consideration for a Partnership Interest, (iii) the Partnership is liquidated within the meaning of Treasury Regulation Section 1.704-1(b)(2)(ii)(g), or (iv) at such other times as the General Partner may determine so long as such adjustment is made under generally accepted industry accounting practices within the meaning of Treasury Regulations Section 1.704-1(b)(2)(iv)(f)(5), the General Partner shall revalue the property of the Partnership to its fair market value (as determined by the General Partner, in its sole and absolute discretion, and taking into account Section 7701(g) of the Code) in accordance with Regulations Section 1.704-1(b)(2)(iv)(f). When the Partnership’s property is revalued by the General Partner, the Capital Accounts of the Partners shall be adjusted in accordance with Treasury Regulations Sections 1.704-1(b)(2)(iv)(f) and (g), which generally require such Capital Accounts to be adjusted to reflect the manner in which the unrealized gain or loss inherent in such property (that has not been reflected in the Capital Accounts previously) would be allocated among the Partners pursuant to Section 6.1 if there were a taxable disposition of such property for its fair market value (as determined by the General Partner, in its sole and absolute discretion, and taking into account Section 7701(g) of the Code) on the date of the revaluation.

5.Distributions.

5.1Distributions.

(a)General. Subject to the provisions of Sections 5.3, 5.4, 8.6(b), 11.6(d), and 13.2, the General Partner shall cause the Partnership to distribute cash to the Partners in amounts proportionate to their respective Percentage Interests as of the applicable Partnership Record Date, at such times as the General Partner shall determine.

(b)Adjustment for Stockholder Servicing Fee and Other Class Specific Items. To the extent the payment of the Stockholder Servicing Fee reduces cash otherwise available for distribution, such cash available for distribution shall be deemed increased by the amount of the Stockholder Servicing Fee for purposes of Section 5.1(a), but the amount equal to the Stockholder Servicing Fee paid will reduce the distributions with respect to the Partnership Class T Units associated with the shares of REIT Class T Stock intended to be burdened by the Stockholder Servicing Fee. For example, assume the Partnership has $9,200,000 of available

cash for distribution, has 2,000,000 Partnership Class T Units and 500,000 Partnership Class I Units outstanding, and had paid, on behalf of the General Partner or AHR, $800,000 on account of the Stockholder Servicing Fee associated with REIT Class T Stock. Cash available for purposes of Section 5.1(a) will be deemed to be $10,000,000 ($9,200,000 + $800,000), which will initially get apportioned in accordance with the Partnership Percentage Interests, or $8,000,000 to the Partnership Class T Units (2,000,000 Partnership Class T Units / 2,500,000 total Partnership Units) and $2,000,000 to the Partnership Class I Units (500,000 Partnership Class I Units / 2,500,000 total Partnership Units). Thereafter, $7,200,000 ($8,000,000 less the $800,000 for the Stockholder Servicing Fee) would be distributed on account of the Partnership Class T Units (or $3.60 per Partnership Class T Unit). And $2,000,000 would be distributed on account of the Partnership Class I Units (or $4.00 per Partnership Class I Unit). Similar adjustments to cash available for distribution, and a concomitant increase or decrease in distributions with respect to Partnership Interests, shall be made for any other items of income, gain, loss or deduction of the General Partner that are allocable to a specific class or series Partnership Units in the manner contemplated by Section 6.1(d).

5.2Qualification as a REIT. The General Partner shall take such action as it deems necessary or advisable to cause the Partnership to distribute sufficient amounts under this Section 5 to enable AHR to pay stockholder dividends that will enable AHR to (a) satisfy the requirements for qualification as a REIT under the Code and the Treasury Regulations (the “REIT Requirements”), and (b) avoid any Federal income or excise tax liability; provided, however, the General Partner shall not be bound to comply with this covenant to the extent such distributions would violate applicable Delaware law.

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

5.4Additional Partnership Interests. If the Partnership issues Partnership Interests in accordance with Section 4.2 or 4.3, the distribution priorities set forth in Section 5.1 shall be amended, as necessary, to reflect any distribution priority of such Partnership Interests and corresponding amendments shall be made to the provisions of Section 6; provided, that any such amendment proposed in connection with an issuance of Partnership Interests under Section 4.2 (but not Section 4.3) must comply with Section 14.1(b). If a new or existing Partner acquires an additional Partnership Interest in exchange for a Capital Contribution on any date other than a Partnership Record Date, such Partner shall not be entitled to any distributions with respect to such additional Partnership Interest until the first Partnership Record Date following the date of such issuance.

6.Allocations.

6.1Allocation of Profits and Losses.

(a)General. Except as otherwise provided in this Section 6.1 (including as a result of the application of Section 6.3) and in Section 11.6(c), and after making any special allocations under Section 6.2, Profits and Losses for each Fiscal Year shall be allocated among the Partners in accordance with their respective Percentage Interests as of the end of such Fiscal Year, subject to any rights of holders of Partnership Interests other than Partnership Units.

(b)Adjustment. If the amount of Losses for any Fiscal Year that otherwise would be allocated to a Partner under Section 6.1(a) or this Section 6.1(b) would cause or increase an Adjusted Capital Account Deficit of such Partner as of the last day of such Fiscal Year (after all other allocations have been made pursuant to this Section 6), then such Partner shall be allocated that amount of Losses which does not cause or increase such Adjusted Capital Account Deficit, and the remainder of such Losses that would have been allocated to such Partner shall be allocated to the other Partners in proportion to their Percentage Interests.

(c)Alternative Allocations. It is the Partners’ intention that each Partners’ distributive share of income, gain, loss, deduction, credit (or item thereof) be determined and allocated consistently with the provisions of the Code, including Sections 704(b) and 704(c) of the Code. If the General Partner deems it necessary in order to comply with the Code, then the General Partner may, relying upon the advice of the Partnership’s accountants, cause the Partnership to allocate income, gain, loss, deduction or credit (or items thereof) arising in any year differently than as provided for in this Section 6 if, and to the extent, (a) allocating income, gain, loss, deduction or credit (or item thereof) would cause the determinations and allocations of each Partner’s distributive share of income, gain, loss, deduction or credit (or item thereof) not to be permitted by the Code and any applicable Regulations or (b) such allocation would be inconsistent with a Partner’s interest in the Partnership taking into consideration all facts and circumstances. Any allocation made pursuant to this Section 6.1(c) will be a complete substitute for any allocation otherwise provided for in this Agreement, and no further amendment of this Agreement or approval by any Partner is necessary to effectuate such allocation. In making any such allocations under this Section 6.1(c) (“New Allocations”), the Partnership may act in reliance upon advice of counsel to the Partnership or the Partnership’s regular accountants that, in either case, in their respective opinions after examining the relevant provisions of the Code and any current or future proposed or final Regulations, the New Allocations are necessary in order to ensure that, in either the Fiscal Year or in any preceding year, each Partner’s distributive share of income, gain, loss, deduction or credit (or items thereof) is determined and allocated in accordance with the Code and such Partner’s interest in the Partnership. New Allocations made by the General Partner in reliance upon the advice of counsel or accountants, as described in this Section 6.1(c), will be deemed to be in the best interests of the Partnership and all of the Partners consistent with the duties of the General Partner under this Agreement, and any such New Allocations will not give rise to any claim or cause of action by any Partner against the Partnership or the General Partner.

(d)Special Allocation of Expense of Stockholder Servicing Fee and other Class Specific Items. If the Partnership directly or on behalf of AHR incurs any expense for the

Stockholder Servicing Fee, such amounts shall be specially allocated among the Partnership Class T Units to correspond with their appropriate share of such expenses. To the extent that any other items of income, gain, loss or deduction of AHR are allocable to a specific class or series of REIT Stock as provided in AHR’s Prospectus, such items, or an amount equal thereto, shall be specially allocated to the class or series of Partnership Units corresponding to such class or series of REIT Stock.

6.2Special Allocations. Notwithstanding any provisions of Section 6.1, the following special allocations shall be made in the following order of priority:

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

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

(c)Qualified Income Offset. In the event a Partner unexpectedly receives any adjustment, allocation or distribution described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), (5) and (6) that causes or increases an Adjusted Capital Account Deficit, gross items of income and gain shall be specially allocated to such Partner so as to eliminate such Adjusted Capital Account Deficit as quickly as possible. This subparagraph is intended to constitute a “qualified income offset” under Section 1.704-1(b)(2)(ii)(d) of the Treasury Regulations and shall be interpreted consistently therewith.

(d)Nonrecourse Deductions. Nonrecourse Deductions for any Fiscal Year shall be allocated to the Partners in accordance with their respective Percentage Interests.

(e)Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any Fiscal Year with respect to a Partner Nonrecourse Debt shall be specially allocated to the Partners that bear the economic risk of loss for such Partner Nonrecourse Debt (as determined under Treasury Regulations Sections 1.704-2(b)(4) and 1.704-2(i)(1).

(f)Definition of “Profits” and “Losses.” “Profits” and “Losses” and any item of income, gain, expense, or loss referred to in this Agreement shall be determined in accordance with federal income tax accounting principles, as modified by Treasury Regulations Section 1.704-1(b)(2)(iv), except that Profit and Loss shall not include items of income, gain and expense that are specially allocated pursuant to Sections 6.1(b), 6.1(d), 6.2(a), 6.2(b), 6.2(c), 6.2(d), and 6.2(e). All allocations of Profit and Loss (and all items contained therein) for federal income tax purposes shall be identical to all allocations of such items set forth in Section 6.1 and this Section 6.2, except as otherwise required by Section 704(c) of the Code and Regulations Section 1.704-1(b)(4). The General Partner shall have the authority to elect the method to be used by the Partnership for allocating items of income, gain, and expense as required by Section 704(c) of the Code including a method that may result in a Partner receiving a disproportionately larger share of the Partnership tax depreciation deductions, and such election shall be binding on all Partners.

(g)Curative Allocations. The allocations set forth in Section 6.1(b) and Sections 6.2(a) through 6.2(e) hereof (the “Regulatory Allocations”) are intended to comply with certain requirements of the Treasury Regulations. It is the intent of the Partners that, to the extent possible all Regulatory Allocations that are made be offset either with other Regulatory Allocations or with special allocations pursuant to this Section 6.2(g). Therefore, notwithstanding any other provision of this Section 6 (other than the Regulatory Allocations), the General Partner shall make such offsetting special allocations 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 Sections 6.1(a) and 6.1(c). In exercising its discretion under this Section 6.2(g), the General Partner shall take into account future Regulatory Allocations under Sections 6.2(a) and 6.2(b) that, although not yet made, are likely to offset other Regulatory Allocations previously made under Sections 6.2(d) and 6.2(e).

(h)Changes in Interest. If during any Fiscal Year there is a change in any Partner’s Percentage Interest, then for purposes of determining the Profits, Losses, or any other items allocable to such Partner for such Fiscal Year, 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 Code Section 706 and the Treasury Regulations thereunder.

6.3Revisions to Allocations to Reflect Issuance of Partnership Interests. If the Partnership issues Partnership Interests to the General Partner or any additional Limited Partner pursuant to Section 4, the General Partner shall make any such revisions to this Section 6 as it deems necessary to reflect the terms of the issuance of such Partnership Interests, including making preferential allocations to classes of Partnership Interests that are entitled thereto. Such revisions shall not require the consent or approval of any other Partner.

7.Management and Operations of Business.

7.1Management.

(a)Management By the General Partner. Except as otherwise expressly provided in this Agreement, full, complete and exclusive discretion to manage and control the business and affairs of the Partnership are and shall be vested in the General Partner, and no Limited Partner shall have any right to participate in or exercise control or management power over the business and affairs of the Partnership. The General Partner may not be removed by the Limited Partners.

(b)Power and Authority of the General Partner. Subject to any limitations set forth in this Agreement, in addition to the powers now or hereafter granted to a general partner of a limited partnership under applicable law or which are granted to the General Partner under any other provision of this Agreement, the General Partner shall have full power and authority to do all things deemed necessary or desirable by it to conduct the business of the Partnership, to exercise all powers on behalf of the Partnership set forth in Section 3.2 hereof and to effectuate the purposes set forth in Section 3.1 hereof on behalf of the Partnership hereof, including, without limitation:

(iv)the use of the assets of the Partnership (including, without limitation, cash on hand) for any purpose consistent with the terms of this Agreement and on any terms the General Partner sees fit, including, without limitation,

(xi)the formation of, or acquisition of an interest (including non-voting interests in entities controlled by Affiliates of the Partnership or by third parties) in, and the contribution of property to, any other Entities by the Partnership that the General Partner deems desirable (including, without limitation, the acquisition of interests in, and the contributions of funds or property to, or making of loans to, Subsidiaries of the Partnership and any other Person from time to time), or the incurrence of indebtedness on behalf of such Persons or the guarantee of the obligations of such Persons; provided that, as long as AHR has determined to elect to qualify as a REIT or to continue to qualify as a REIT, the Partnership may not engage in any such formation, acquisition or contribution that would cause AHR to fail to qualify as a REIT;

(xii)the control of any matters affecting the rights and obligations of the Partnership, including:

(A)the settlement, compromise, submission to arbitration or any other form of dispute resolution, or abandonment of, any claim, cause of action, liability, debt or damages, due or owing to or from the Partnership;

Capital Contributions, redemptions, issuance of Partnership Units, admission of any Additional Limited Partner or any Substituted Limited Partner or otherwise, which amendment and restatement, notwithstanding anything in this Agreement to the contrary, shall not be deemed an amendment of this Agreement, as long as the matter or event being reflected in Exhibit A otherwise is authorized by this Agreement.

(c)Insurance. At all times from and after the date hereof, the General Partner may cause the Partnership to obtain and maintain:

(i)casualty, liability and other insurance on the Real Estate Assets of the Partnership;

(ii)liability insurance for the Indemnitees hereunder; and

(d)Working Capital and Other Reserves. At all times from and after the date hereof, the General Partner may cause the Partnership to establish and maintain at any and all times working capital accounts and other cash or similar balances in such amount as the General Partner, in its sole and absolute discretion, deems appropriate and reasonable from time to time, provided that so long as AHR qualifies as a REIT, the General Partner will not establish reserves to the extent such establishment would prevent AHR from making distributions to its stockholders in amounts sufficient to permit AHR to maintain its REIT status).

7.2Certificate of Limited Partnership. The Initial General Partner has previously filed the Certificate with the Secretary of State of Delaware as required by the Act. The General Partner shall use all reasonable efforts to cause to be filed such other certificates or documents as may be reasonable and necessary or appropriate for the formation, continuation, qualification and operation of the Partnership as a limited partnership (or a partnership in which the limited partners have limited liability) in the State of Delaware and any other state, or the District of Columbia, in which the Partnership may elect to do business or own property. To the extent that such action is determined by the General Partner to be reasonable and necessary or appropriate and consistent with the terms and conditions of this Agreement (including, without limitation, Section 14.1(b)), the General Partner shall file amendments to and restatements of the Certificate and do all of the things to maintain the Partnership as a limited partnership (or a partnership in which the limited partners have limited liability) under the laws of the State of Delaware and each other state, or the District of Columbia, in which the Partnership may elect to do business or own property. Subject to the terms of Section 8.5(a)(iii) hereof, the General Partner shall not be required, before or after filing, to deliver or mail a copy of the Certificate or any amendment thereto to any Limited Partner.

7.3Reimbursement of the General Partner and AHR.

(a)No Compensation. Except as provided in this Section 7.3 and elsewhere in this Agreement (including the provisions of Sections 5 and 6 regarding distributions, payments, and allocations to which it may be entitled), the General Partner shall not be compensated for its services as general partner of the Partnership.

(b)Responsibility for Partnership Expenses. The Partnership shall be responsible for and shall pay all expenses relating to the Partnership’s organization and the ownership and operation of the Partnership Assets. The General Partner and AHR shall be reimbursed on a monthly basis, or such other basis as the General Partner may determine in its sole and absolute discretion, for all expenses that either of them incurs on behalf of the Partnership relating to the ownership and operation of the Partnership Assets, or for the benefit of the Partnership; provided, that the amount of any such reimbursement shall be reduced by any interest earned by the General Partner or AHR with respect to bank accounts or other instruments or accounts held by it on behalf of the Partnership. Such reimbursement shall be in addition to any reimbursement made as a result of indemnification pursuant to Section 7.6 hereof.

(c)Responsibility for General Partner Expenses and AHR Expenses. The General Partner and AHR shall also be reimbursed for (i) all expenses related to the operations of the General Partner and AHR and to the management and administration of any Subsidiaries of the Partnership or Affiliates of the Partnership, such as auditing expenses and filing fees and any and all salaries, compensation and expenses of officers and employees of the General Partner and AHR, and (ii) all expenses the General Partner and AHR incurs relating to the organization and/or reorganization of the Partnership and the General Partner, the public offering of REIT Stock and other Securities by AHR, and any other offering, grant, award or issuance of REIT Stock or Securities or additional Partnership Interests pursuant to Section 4.2 or 4.3, including all expenses associated with compliance by the General Partner and/or AHR with laws, rules and regulations promulgated by any regulatory body.

(d)Business of the General Partner. The Limited Partners acknowledge that the sole business of the General Partner and AHR is the ownership of direct or indirect interests in, and the direct or indirect operation of, the Partnership, and that all of the expenses of the General Partner and AHR are incurred for the benefit of the Partnership. Notwithstanding any other provisions of this Agreement (including, without limitation Section 7.1(b)), the General Partner and AHR will conduct all business exclusively through the Partnership and shall own no assets other than Partnership Interests or equity interests in entities owning only Partnership Interests.

(e)Characterization of Reimbursements. All payments and reimbursements hereunder shall be characterized for Federal income tax purposes as expenses of the Partnership incurred on its behalf, and not as expenses of the General Partner.

7.4Acquisition of Limited Partner Interests by the General Partner. The General Partner and any Affiliates of the General Partner may acquire Limited Partner Interests and shall be entitled to exercise all rights of a Limited Partner relating to such Limited Partner Interests.

7.5Transactions with Affiliates.

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

(b)Certain Transactions with the Advisor and its Affiliates. Notwithstanding anything to the contrary in this Agreement, the General Partner shall not cause the Partnership, directly or indirectly, to Transfer any property to, purchase any property from, loan any money to, borrow any money from or enter into any other transaction with any director of the General Partner or any Affiliate thereof, except in accordance with the procedures set forth in the Articles of Incorporation for such transactions.

(c)Benefit Plans Sponsored by the Partnership. The General Partner, in its sole and absolute discretion and without the approval of the Limited Partners, may propose and adopt, on behalf of the Partnership, employee benefit plans, option or other equity incentive plans, and similar plans funded by the Partnership for the benefit of employees of the Partnership, AHR, the General Partner, any Subsidiaries of the Partnership or any Affiliate of any of them in respect of services performed, directly or indirectly, for the benefit of the Partnership, AHR, the General Partner, any Subsidiaries of the Partnership or any of their respective Affiliates.

7.6Indemnification.

(a)General. Subject to the limitations of Section 7.6(b), to the maximum extent permitted under the Act in effect from time to time, the Partnership shall indemnify each Indemnitee from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including, without limitation, reasonable attorneys’ fees and other legal fees and expenses), judgments, fines, settlements, and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative (collectively, “Claims”), that relate to the operations of the Partnership, AHR, the General Partner or any of the Partnership’s Subsidiaries in which such Indemnitee may be involved, or is threatened to be involved, as a party or otherwise; provided, however, that in no event shall this Section 7.6(a) enlarge the indemnification permitted below under Section 7.6(b).

(b)Limitation. Notwithstanding any provision hereof to the contrary:

(i)the Partnership will not indemnify any Indemnitee if it is established that:

(A)the act or omission of the Indemnitee was material to the matter giving rise to the proceeding and either was committed in bad faith or was the result of active and deliberate dishonesty,

(B)the Indemnitee actually received an improper personal benefit in money, property or services, or

(C)in the case of any criminal proceeding, the Indemnitee had reasonable cause to believe that the act or omission was unlawful;

(ii)any indemnification or agreement to hold harmless may be paid only out of the Net Assets of the Partnership, and neither the General Partner nor any Limited Partner shall have any obligation to contribute to the capital of the Partnership, or otherwise provide funds, to enable the Partnership to fund its obligations under this Section 7.6.

(c)Contractual Obligations. Without limitation, the indemnity set forth in this Section 7.6 shall extend to any liability of any Indemnitee pursuant to a loan guaranty (except a guaranty by a Limited Partner of nonrecourse indebtedness of the Partnership or as otherwise provided in any such loan guaranty), contractual obligation for any indebtedness or other obligation or otherwise for any indebtedness of the Partnership or any Subsidiary of the Partnership (including, without limitation, any indebtedness that the Partnership or any Subsidiary of the Partnership has assumed or taken subject to), and the General Partner is hereby authorized and empowered, on behalf of the Partnership, to enter into one or more indemnification agreements consistent with the provisions of this Section 7.6 in favor of any Indemnitee having or potentially having liability for any such indebtedness.

(d)Advancement of Expenses. Reasonable expenses incurred by an Indemnitee who is a party to a proceeding shall be paid or reimbursed by the Partnership in advance of the final disposition of any and all Claims made or threatened against an Indemnitee if all of the following conditions are satisfied: (i) the Claim relates to acts or omissions with respect to the performance of duties or services on behalf of the Partnership, General Partner, or any of their Subsidiaries, (ii) the Indemnitee provides the Partnership with a written affirmation by the Indemnitee of the Indemnitee’s good faith belief that the standard of conduct necessary for indemnification by the Partnership as authorized in this Section 7.6 has been met, and (iii) the Indemnitee provides the Partnership with a written undertaking to repay the amount paid or reimbursed by the Partnership, together with the applicable legal rate of interest thereon, if it is ultimately determined that the Indemnitee did not comply with the requisite standard of conduct and is not entitled to indemnification.

(e)No Exclusivity. The indemnification provided by this Section 7.6 shall be in addition to any other rights to which an Indemnitee or any other Person may be entitled under any agreement, pursuant to any vote of the Partners, as a matter of law or otherwise, and shall continue as to an Indemnitee who has ceased to serve in such capacity unless otherwise provided in a written agreement pursuant to which such Indemnitees are indemnified.

(f)Insurance. The Partnership may purchase and maintain insurance, on behalf of the Indemnitees and such other Persons as the General Partner shall determine, against any liability that may be asserted against or expenses that may be incurred by such Person in connection with the Partnership’s activities, regardless of whether the Partnership would have the power to indemnify such Person against such liability under the provisions of this Agreement.

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

(h)No Personal Liability for Partners. In no event may an Indemnitee subject any of the Partners to personal liability by reason of the indemnification provisions set forth in this Agreement.

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

(j)Benefit. The provisions of this Section 7.6 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

(k)Amendment of this Section 7.6. Any amendment, modification or repeal of this Section 7.6 or any provision hereof shall be prospective only and shall not in any way affect the Partnership’s liability to any Indemnitee under this Section 7.6, as in effect immediately prior to such amendment, modification, or repeal with respect to Claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such Claims may arise or be asserted.

(l)Indemnification Payments Not Distributions. If and to the extent any payments to the General Partner pursuant to this Section 7.6 constitute gross income to the General Partner (as opposed to the repayment of advances made on behalf of the Partnership), such amounts shall constitute guaranteed payments within the meaning of Section 707(c) of the Code, shall be treated consistently therewith by the Partnership and all Partners, and shall not be treated as distributions for purposes of computing the Partners’ Capital Accounts.

(m)Exception to Indemnification. Notwithstanding anything to the contrary in this Agreement, the General Partner shall not be entitled to indemnification hereunder for any Claim for which the General Partner is obligated to indemnify the Partnership under any other agreement between the General Partner and the Partnership.

7.7Liability of the General Partner.

(a)General. To the maximum extent permitted under the Act, the only duties that the General Partner owes to the Partnership, any Partner or any other Person (including any creditor of any Partner or assignee of any Partnership Interest) are to perform its contractual obligations as expressly set forth in this Agreement consistent with the obligation of good faith and fair dealing, and to act with the duties of care and loyalty which have been, in accordance with the Act, modified as set forth in this Section 7.7. The General Partner, in its capacity as such, shall have no other duty, fiduciary or otherwise, to the Partnership, any Partner or any other Person (including any creditor of any Partner or any assignee of Partnership Interest). The provisions of this Agreement other than this Section 7.7 shall create contractual obligations of the General Partner only, and no such provision shall be interpreted to expand or modify the fiduciary duties of the General Partner under the Act. To the maximum extent permitted under the Act, neither the General Partner nor any director, officer, stockholder, partner, member or employee, trustee, representative or agent of the General Partner (including AHR, the Advisor

and their Affiliates and their respective members, managers, partners, equity holders, officers, directors and employees) shall be liable to the Partnership or to any Partner for (i) any act or omission performed or failed to be performed by it, or for any losses, claims, costs, damages, or liabilities arising from any such act or omission, (ii) any tax liability imposed on the Partnership or (iii) any losses due to the misconduct, negligence (gross or ordinary), dishonesty or bad faith of any agents of the Partnership. Notwithstanding anything to the contrary in this Section 7.7(a), this limitation on liability applies only to the extent that the particular officer or director has satisfied the requirements of Section 7.6(b)(i).

(b)No Obligation to Consider Separate Interests of Limited Partners. The Limited Partners expressly acknowledge that (i) the General Partner is acting on behalf of the Partnership and (as an agent of AHR) the stockholders of AHR, collectively, (ii) the General Partner is under no obligation to consider the separate interest of the Limited Partners (including, without limitation, the tax consequences to Limited Partners or Assignees) in deciding whether to cause the Partnership to take (or decline to take) any actions, and (iii) neither AHR, the General Partner nor the Advisor shall be liable for monetary damages for losses sustained, liabilities incurred, or benefits not derived by Limited Partners in connection with such decisions, unless AHR, the General Partner or the Advisor, as the case may be, acted in bad faith, the act or omission was material to the matter giving rise to the loss, liability or benefit not derived, and the Limited Partner adversely affected reasonably expected to avoid the loss or liability or reasonably expected to accrue the benefit not derived.

(c)Conflict. The Limited Partners expressly acknowledge that in the event of any conflict in the duties owed by the General Partner or the Advisor to the General Partner’s stockholders or members, and by the General Partner or the Advisor, in their respective capacities as the general partner of or advisor to the Partnership (as the case may be), to the Limited Partners, the General Partner and the Advisor may give priority to the interests of the General Partner’s stockholders or members and doing so will not violate the contract rights of the Limited Partners under this Agreement and will not violate any duty owed by the General Partner to the Partnership and the Limited Partners, and that neither the General Partner nor the Advisor shall be liable for monetary damages for losses sustained, liabilities incurred, or benefits not derived by the Limited Partners in connection with giving any priority to the interests of the General Partner’s stockholders.

(d)Amendment of this Section 7.7. Any amendment, modification or repeal of this Section 7.7 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the General Partner’s, the Advisor’s and their respective members’, managers’ partners’, equity holders’, officers’, directors’, trustees’, representatives’, agents’ or Affiliate’s liability to the Partnership and the Limited Partners under this Section 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

7.8Other Matters Concerning the General Partner.

(a)Reliance on Documents. The General Partner and the Advisor may rely and shall be protected in acting, or refraining from acting, upon any resolution, certificate,

statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties.

(b)Reliance on Advisors. The General Partner and the Advisor may consult with legal counsel, accountants, appraisers, management consultants, investment bankers, architects, engineers, environmental consultants and other consultants and advisers selected by either of them, and any act taken or omitted to be taken in reliance upon the opinion of such Persons as to matters which the General Partner or the Advisor reasonably believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion.

(c)Action Through Agents. The General Partner shall have the right, in respect of any of its powers or obligations hereunder, to act through any of its duly authorized officers, agents, and duly appointed attorneys-in-fact. Each such officer, agent, or attorney-in-fact shall, to the extent granted by the General Partner or the Advisor in writing, have full power and authority to do and perform each and every act and duty which is permitted or required to be done by the General Partner or the Advisor hereunder.

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

7.9Title to Partnership Assets. Title to all Partnership Assets, whether real, personal or mixed and whether tangible or intangible, shall be deemed to be held by the Partnership as an entity, and no Partner, individually or collectively, shall have any ownership interest in the Partnership Assets or any portion thereof. Title to any or all of the Partnership Assets may be held in the name of the Partnership, the General Partner or one or more nominees, as the General Partner may determine, including Affiliates of the General Partner. The General Partner hereby declares and warrants that any Partnership Asset for which legal title is held in the name of the General Partner or any nominee or Affiliate of the General Partner shall be held by the General Partner for the use and benefit of the Partnership in accordance with the provisions of this Agreement; provided, that the General Partner shall use reasonable efforts to cause beneficial and record title to such assets to be vested in the Partnership as soon as reasonably practicable. All Partnership Assets shall be recorded as the property of the Partnership in its books and records, irrespective of the name in which legal title to such Partnership Assets is held.

7.10Reliance by Third Parties.

(a)Notwithstanding anything to the contrary in this Agreement, any Person dealing with the Partnership shall be entitled to assume that the General Partner has full power and authority, without the consent or approval of any other Partner or Person, to encumber, sell or otherwise use in any manner any and all Partnership Assets and to enter into any contracts on behalf of the Partnership, and take any and all actions on behalf of the Partnership, and such Person shall be entitled to deal with the General Partner as if the General Partner were the Partnership’s sole party in interest, both legally and beneficially.

8.Rights and Obligations of Limited Partners.

8.1Limitation of Liability. The Limited Partners shall have no liability under this Agreement, except as may be expressly provided in this Agreement (including without limitation Section 10.5 hereof) or under the Act.

8.2No Right to Participate in the Management of Business. No Limited Partner shall take part in the management or control of the Partnership’s investment or other activities, transact any business in the Partnership’s name or have the power to sign documents for or otherwise bind the Partnership. Except as expressly provided herein, no Limited Partner shall have the right to vote for the election, removal or replacement of the General Partner. The exercise by any Limited Partner of any right conferred herein shall not be construed to constitute participation by such Limited Partner in the control of the business of the Partnership so as to

make such Limited Partner liable as a general partner for the debts and obligations of the Partnership for purposes of the Act, laws of non-U.S. jurisdictions or otherwise.

8.3Outside Activities of Limited Partners. Subject to any agreements entered into by a Limited Partner or its Affiliates, or any Assignee, with the Partnership or any of its Subsidiaries, any Limited Partner or Assignee and any officer, director, employee, agent, trustee, Affiliate or stockholder or other equity owner of any Limited Partner or Assignee shall be entitled to and may have business interests and engage in business activities in addition to those relating to the Partnership, including business interests and activities that are in direct competition with the Partnership or that are enhanced by the activities of the Partnership. Neither the Partnership nor any of the Partners shall have any rights by virtue of this Agreement in any business ventures of any other Partner or Assignee. None of the Limited Partners nor any other Person shall have any rights by virtue of this Agreement, or the Partnership relationship established hereby, in any business ventures of any other Person, and such Person shall have no obligation pursuant to this Agreement to offer any interest in any such business ventures to the Partnership, any Limited Partner, or any such other Person, even if such opportunity is of a character which, if presented to the Partnership, any Limited Partner, or such other Person, could be taken by such Person.

8.4Return of Capital. No Limited Partner shall be entitled to the withdrawal or return of its Capital Contribution, except (a) to the extent of such Limited Partner’s right of redemption set forth in Section 8.6, and (b) to the extent that the General Partner (or the Liquidator) determines to make distributions made pursuant to this Agreement or upon termination of the Partnership, as provided herein. Except as otherwise expressly provided in this Agreement, no Limited Partner or Assignee shall have priority over any other Limited Partner or Assignee, either as to the return of Capital Contributions or as to distributions or allocations of Profits or Losses.

8.5Rights of Limited Partners Relating to the Partnership.

(a)General. In addition to the other rights provided by this Agreement and any rights granted to limited partners of a limited partnership under the Act that such limited partners are not permitted to waive under the Act, and except as limited by Section 8.5(b) hereof, each Limited Partner shall have the right, for a purpose reasonably related to such Limited Partner’s interest as a limited partner in the Partnership, upon written demand with a statement of the purpose of such demand and at such Limited Partner’s own expense (including such reasonable copying and administrative charges as the General Partner may establish from time to time):

(i)to obtain a copy of the Partnership’s federal, state and local income tax returns for each Fiscal Year;

(ii)to obtain a current list of the name and last known business, residence or mailing address of each Partner of record; and

(iii)to obtain a copy of this Agreement, the Certificate, and all amendments to either, together with executed copies of all powers of attorney pursuant to which this Agreement, the Certificate, and all amendments to either have been executed.

Each Limited Partner hereby waives any and all rights that such Limited Partner may have under the Act that the Act permits limited partners to waive, except any such right that is granted expressly to such Limited Partner under this Agreement.

(b)Confidentiality. Notwithstanding any other provision of this Section 8.5, the General Partner may keep confidential from the Limited Partners, for such period of time as the General Partner determines in its sole and absolute discretion to be reasonable, any information that:

(i)the General Partner reasonably believes to be in the nature of trade secrets or other information, the disclosure of which the General Partner in good faith believes is not in the best interests of the Partnership or General Partner or could damage the Partnership or General Partner or its or their business; or

(ii)the Partnership is required by law or by agreements with an unaffiliated third party to keep confidential.

8.6Redemption Right.

(a)Redemption Right. Subject to Section 8.6(l) and the other provisions of this Section 8.6, at any time on or after the first anniversary date of the issuance of a Partnership Unit to a Partner, such Partner shall have the right (the “Redemption Right”) to require the Partnership to redeem on a Specified Redemption Date all or a portion of the Partnership Units held by such Partner, at a redemption price equal to and in the form of the Redemption Amount. The Redemption Right shall be exercised pursuant to a Notice of Redemption Request delivered to the General Partner by the Partner who is exercising the Redemption Right (the “Redeeming Partner”).

(b)Distributions and Allocations.

(i)Subject to Section 8.6(c), the Redeeming Partner shall have no right to receive any distributions that are paid after the Specified Redemption Date with respect to any Partnership Units redeemed pursuant to this Section 8.6.

(ii)If any Partnership Interest is redeemed (other than pursuant to Section 8.6(c)) on any day other than the first day of a Fiscal Year, then Profit, Losses, each item thereof and all other items attributable to such Partnership Interest for such Fiscal Year shall be divided and allocated to the Redeeming Partner by taking into account the Redeeming Partner’s ownership of such Partnership Interest during the Fiscal Year in accordance with Section 706(d) of the Code, using the interim closing of the books method (unless the General Partner, in its sole and absolute discretion, elects to adopt a daily, weekly or monthly proration period, in which event Profits, Losses, each item thereof and all other items attributable to such redeemed Partnership Interest for such Fiscal Year shall be prorated based upon the applicable method selected by the General Partner).

(c)AHR Assumption of Obligation. Notwithstanding the provisions of Section 8.6(a), AHR may, in its sole and absolute discretion (subject to the limitations on ownership and transfer of shares of REIT Stock in the Articles of Incorporation), assume directly the obligation to satisfy a Redemption Right and satisfy such Redemption Right by paying to the Redeeming Partner the Redemption Amount on the Specified Redemption Date, whereupon AHR shall acquire the Partnership Units offered for redemption by the Redeeming Partner and shall be treated for all purposes of this Agreement as the owner of such Partnership Units. In the event that AHR shall exercise this right to satisfy the Redemption Right in the manner described in the preceding sentence and shall fully perform its obligation to pay the Redemption Amount on the Specified Redemption Date, the Partnership shall have no obligation to pay any amount to the Redeeming Partner with respect to such Redeeming Partner’s exercise of the Redemption Right, and each of the Redeeming Partner, the Partnership, the General Partner and AHR shall treat the transaction between AHR and the Redeeming Partner as a sale of the Redeeming Partner’s Partnership Units to AHR for federal income tax purposes. Distributions and allocations with respect to Partnership Units acquired by AHR pursuant to this Section 8.6(c) shall be made in accordance with Sections 11.6(c) and 11.6(d).

(d)Fractional Shares. If AHR elects, either on its own behalf or on behalf of the Partnership, to satisfy the Redemption Right by paying the REIT Stock Amount, and the REIT Stock Amount is not equal to a whole number of shares of REIT Stock, the Redeeming Partner shall be paid (i) that number of shares of REIT Stock which equals the nearest whole number less than the REIT Stock Amount, plus (ii) (A) an amount of cash equal to the Value of one share of REIT Stock on the applicable Valuation Date, multiplied by (B) the REIT Stock Amount minus the whole number of shares of REIT Stock pursuant to clause (i) of this Section 8.6(d).

(e)Execution of Documents. Each Redeeming Partner agrees to execute such documents as the General Partner and/or AHR may reasonably require in connection with (i) the exercise and satisfaction of the Redemption Right, (ii) any assumption by AHR pursuant to Section 8.6(c), and (iii) any issuance of REIT Stock in connection with the Partnership or AHR paying the Redemption Amount to the Redeeming Partner.

(f)Exceptions to Redemption Right. Other than as set forth in Section 8.6(l), notwithstanding the provisions of Section 8.6(a), unless the General Partner elects for payment of the Redemption Amount by the Partnership to be the Cash Amount, a Partner shall not be entitled to exercise the Redemption Right if the delivery of REIT Stock to such Partner on the Specified Redemption Date would (i) be prohibited under the Articles of Incorporation or the bylaws of AHR, (ii) adversely affect the ability of AHR to continue to qualify as a REIT or subject the General Partner or AHR to any additional taxes under Sections 857 or 4981 of the Code, (iii) constitute or be likely to constitute a violation of any applicable federal or state securities laws or regulations, or (iv) be prohibited under Section 11.6(f) of this Agreement (in each case regardless of whether AHR would in fact assume and satisfy the Redemption Right).

(g)Exercise of the Redemption Right by AHR. The receipt of a notice of redemption with respect to shares of REIT Stock held by stockholders of AHR (a “REIT Notice”) pursuant to AHR’s share repurchase plan as may be in effect from time to time shall be deemed to be a Notice of Redemption Request given by the General Partner to the Partnership.

The redemption by AHR of REIT Stock pursuant to a REIT Notice shall be deemed an exercise of the Redemption Right with respect to the class of and number of Partnership Units equal to the corresponding class and number of shares of REIT Stock identified in the REIT Notice. With respect to any Redemption Right exercised by AHR pursuant to this Section 8.6(g), the General Partner will elect for payment of the Redemption Amount by the Partnership to AHR to be the Cash Amount. Without limiting the foregoing, for example, the Partnership shall redeem from the General Partner Partnership Class T Units in connection with the repurchase by AHR of shares of REIT Class T Stock and shall redeem Partnership Class I Units in connection with the repurchase of shares of REIT Class I Stock.

(h)Assignees. The Assignee of any Limited Partner may exercise the rights of such Limited Partner pursuant to this Section 8.6 with respect to any Partnership Units Transferred by such Limited Partner to such Assignee, and such Limited Partner shall be deemed to have assigned such rights to such Assignee and shall be bound by the exercise of such rights by such Assignee. In connection with any exercise of such rights by such Assignee on behalf of such Limited Partner, the Redemption Amount shall be paid by the Partnership directly to such Assignee and not to such Limited Partner.

(i)No Liens on Partnership Units Delivered for Redemption. Each Partner covenants and agrees that all Partnership Units delivered for redemption pursuant to this Section 8.6 shall be delivered to the Partnership or the General Partner, as the case may be, free and clear of all Liens. Notwithstanding anything contained herein to the contrary, neither the General Partner nor the Partnership shall be under any obligation to acquire Partnership Units which are or may be subject to any Liens. Each Partner further agrees that, if any state or local property transfer tax is payable as a result of the Transfer of its Partnership Units to the Partnership or the General Partner pursuant to this Section 8.6, such Partner shall assume and pay such transfer tax.

(j)Cancellation of Units; Amendments to Exhibit A. Upon the redemption of Partnership Units pursuant to this Section 8.6, (i) all such redeemed Partnership Units (other than Partnership Units redeemed pursuant to Section 8.6(c)) shall be cancelled, and (ii) the General Partner shall amend Exhibit A to reflect the new Percentage Interests of the Partners and to (A) either adjust the number of Partnership Units and the Percentage Interest of the Redeeming Partner or eliminate the Redeeming Partner from Exhibit A, as applicable, and (B) in the event that AHR assumes the obligation to satisfy a Redemption Right pursuant to Section 8.6(c), adjust the number of Partnership Units and the Percentage Interest of AHR to reflect the Transfer of such Partnership Units to AHR.

(k)Additional Partnership Interests. If the Partnership issues Partnership Interests to any Additional Limited Partner pursuant to Section 4, the General Partner shall make such revisions to this Section 8.6 as the General Partner determines are necessary to reflect the issuance of such Partnership Interests (including setting forth any restrictions on the exercise of the Redemption Right with respect to such Partnership Interests).

(l)Redemption Right of AHI Contributors. Pursuant to Section 8.6(a), notwithstanding anything to the contrary in this Agreement:

(i)The Redemption Right associated with the Partnership Units issued in connection with the AHI Platform Acquisition may not be exercised until the expiration of the AHI Contributor Lock-Up Period. Furthermore, upon the Listing Date, such Partnership Units would be subject to further customary restrictions on redemption (for a period not to exceed 180 days) to the extent required by the underwriters or investment bankers engaged by AHR or the General Partner in connection with a Listing Event.

(ii)Subject to clause (iv) below, if a Listing Event has not occurred (or been approved by a national securities exchange) on or before the third anniversary of the issuance of the Partnership Units issued in connection with the AHI Platform Acquisition, unless AHR has submitted an application for a Listing Event with a national securities exchange that has not been denied or withdrawn, the Redemption Amount shall be the Cash Amount with respect to the Partnership Class I (Series A) Units held by an AHI Contributor or a Permitted Transferee thereof.

(iii)Subject to clause (iv) below, if a Listing Event has not occurred (or been approved by a national securities exchange) on or before the fifth anniversary of the issuance of the Partnership Units issued in connection with the AHI Platform Acquisition, unless AHR has submitted an application for a Listing Event with a national securities exchange that has not been denied or withdrawn, the Redemption Amount shall be the Cash Amount with respect to the Partnership Class I (Series B) Units held by an AHI Contributor or a Permitted Transferee thereof.

(iv)Clauses (ii) and (iii) above shall be inapplicable if at the time of the Notice of Redemption Request, in the reasonable determination of AHR’s board of directors, payment of the Cash Amount would have a material adverse effect on the business, assets, liabilities, condition (financial of otherwise), liquidity, or results of operations of AHR or the Partnership, in which case no redemption would occur unless the AHI Contributor or Permitted Transferee elects, in his, her or its sole discretion, to receive the REIT Stock Amount relating to such Notice of Redemption Request.

9.Books, Records, Accounting and Reports.

9.1Records and Accounting.

(a)Books and Records. The General Partner shall keep or cause to be kept at the principal office of the Partnership those records and documents required to be maintained by the Act and other books and records deemed by the General Partner to be appropriate with respect to the Partnership’s business, including, without limitation, all books and records necessary for AHR to comply with applicable REIT Requirements and to provide to the Limited Partners any information, lists, and copies of documents required to be provided pursuant to Sections 8.5(a) and 9.2 hereof.

(b)Accounting Method. The books of the Partnership shall be maintained, for financial and tax reporting purposes, on an accrual basis in accordance with GAAP.

9.2Reports.

(a)Annual Reports. As soon as practicable after the end of each Fiscal Year, but in no event later than the date on which AHR mails its annual report to its stockholders, the General Partner shall cause to be mailed to each Limited Partner as of the close of the Fiscal Year, an annual report containing financial statements of the Partnership, or of AHR, if such statements are prepared on a consolidated basis with the Partnership, for such Fiscal Year, presented in accordance with GAAP, such statements to be audited by a nationally recognized firm of independent public accountants selected by the General Partner in its sole discretion.

(b)Quarterly Reports. If and to the extent that AHR mails quarterly reports to its stockholders, then as soon as practicable after the end of each fiscal quarter of the Partnership, but in no event later than the date such reports are mailed, the General Partner shall cause to be mailed to each Limited Partner a report containing unaudited financial statements as of the last day of the calendar quarter of the Partnership, or of AHR, if such statements are prepared on a consolidated basis with the Partnership, and such other information as may be required by applicable law or regulation, or as the General Partner determines to be appropriate.

(c)Delivery. Notwithstanding the foregoing, the General Partner may deliver to the Limited Partners each of the reports described above, as well as any other communications that it may provide hereunder, by e-mail or by any other electronic means.

10.Tax Matters.

10.1Preparation of Tax Returns. The General Partner shall arrange for the preparation and timely filing of all returns of Partnership income, gains, deductions, losses and other items required of the Partnership for federal and state income tax purposes and shall use commercially reasonable efforts to furnish, within ninety (90) days of the close of each taxable year or as soon as practicable thereafter, the tax information reasonably required by Limited Partners (or former Limited Partners who were limited partners of the Partnership during any portion of such taxable year) for federal and state income tax reporting purposes.

10.2Tax Elections. Except as otherwise provided herein, the General Partner shall, in its sole and absolute discretion, determine whether to make any available election pursuant to the Code; provided, however, that the General Partner shall make the election under Section 754 of the Code in accordance with applicable regulations thereunder. The General Partner shall have the right to seek to revoke any such election it makes, including, without limitation, the election under Section 754 of the Code, upon the General Partner’s determination, in its sole and absolute discretion, that such revocation is in the best interests of the Partners.

10.3Tax Proceedings.

(a)Tax Matters Partner. For tax returns filed with respect to fiscal years beginning before December 31, 2017, this Section 10.3(a) shall apply, and references to Code sections in this Section 10.3(a) refer to the Code sections as in effect prior to such sections’ amendment by the Bipartisan Budget Act of 2015 (P.L. 114-74) (the “2015 Budget Act”).

(i)General. The General Partner shall be the “tax matters partner” of the Partnership for federal income tax purposes. Pursuant to Section 6223(c)(3) of the Code, upon receipt of notice from the Internal Revenue Service of the beginning of an administrative proceeding with respect to the Partnership, the tax matters partner shall furnish the Internal Revenue Service with the name, address, taxpayer identification number, and profit interest of each of the Limited Partners and the Assignees; provided, that such information is provided to the Partnership by the Limited Partners and the Assignees.

(ii)Powers. The tax matters partner is authorized, but not required:

(A)to enter into any settlement with the Internal Revenue Service with respect to any administrative or judicial proceedings for the adjustment of Partnership items required to be taken into account by a Partner for income tax purposes (such administrative proceedings being referred to as a “tax audit” and such judicial proceedings being referred to as “judicial review”), and in the settlement agreement the tax matters partner may expressly state that such agreement shall bind all Partners, except that such settlement agreement shall not bind any Partner:

(1) who (within the time prescribed pursuant to the Code and the Treasury Regulations) files a statement with the Internal Revenue Service providing that the tax matters partner shall not have the authority to enter into a settlement agreement on behalf of such Partner; or

(2) who is a “notice partner” (as defined in Section 6231(a)(8) of the Code) or a member of a “notice group” (as defined in Section 6223(b)(2) of the Code);

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

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

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

(E)to enter into an agreement with the Internal Revenue Service to extend the period for assessing any tax which is attributable to any item required to be taken account of by a Partner for tax purposes, or an item affected by such item; and

(F)to take any other action on behalf of the Partners or the Partnership in connection with any tax audit or judicial review proceeding to the extent permitted by applicable law or regulations.

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

(b)Partnership Representative. For tax returns filed with respect to fiscal years beginning after December 31, 2017, this Section 10.3(b) shall apply, and references to Code sections in this Section 10.3(b) refer to the Code sections as in effect after taking into account the amendments provided by the 2015 Budget Act. The General Partner shall take such reasonable actions as it believes will enhance the avoidance of the application to the Partnership of the provisions of Sections 6221 through 6241 of the Code. If, however, such provisions do apply to the Partnership, the General Partner shall also act as the “partnership representative” for purposes of said Sections 6221 through 6241 of the Code. Each Partner hereby consents to the General Partner serving as the partnership representative and agrees upon request of the General Partner to execute, certify, acknowledge, deliver, swear to, file and record at the appropriate public offices such further documents as may be necessary or appropriate to evidence such consent. The partnership representative will be authorized to represent the Partnership (at the Partnership’s expense) in connection with all examinations of the Partnership’s affairs by tax authorities, including resulting administrative and judicial proceedings, and to (i) sign consents, enter into settlement and other agreements with such authorities with respect to any such examinations or proceedings and (ii) expend the Partnership’s funds for professional services incurred in connection therewith. In such event, the partnership representative shall duly and timely elect under Section 6226 of the Code to require each Person who was a Partner during the taxable year of Partnership that was audited to personally bear any tax, interest and penalty resulting from adjustments based on such audit and shall notify each such Person (and the Internal Revenue Service) of their share of such audit adjustments and, if for any reason, the Partnership is liable for a tax, interest, addition to tax or penalty as a result of such an audit, each Person who was a Partner during the taxable year of the Partnership that was audited, even if such Person is no longer a Partner (unless a Substituted Limited Partner has agreed to bear such liability in an appropriate document evidencing a Transfer), shall pay to the Partnership an amount equal to such Person’s proportionate share of such liability, as determined by the General Partner, based on the amount each such Person should have borne (computed at the tax rate used to compute the Partnership’s liability) had the Partnership’s tax return for such taxable year reflected the audit adjustment, and the expense for the Partnership’s payment of such tax, interest, addition to tax and penalty shall be specially allocated to such Persons (or their successors) in such proportions.

(c)Reimbursements. The tax matters partner shall receive no compensation for its services. All third party costs and expenses incurred by the tax matters partner in performing its duties as such (including legal and accounting fees and expenses) shall be borne by the Partnership. Nothing herein shall be construed to restrict the Partnership from engaging an

accounting firm to assist the tax matters partner in discharging its duties hereunder, so long as the compensation paid by the Partnership for such services is reasonable.

10.4Organizational Expenses. The Partnership shall elect to deduct expenses, if any, incurred by it in organizing the Partnership ratably over a one-hundred eighty (180) month period as provided in Section 709 of the Code.

10.5Withholding.

(a)General. Each Limited Partner hereby authorizes the Partnership to withhold from, or pay on behalf of or with respect to, such Limited Partner any amount of federal, state, local, or foreign taxes that the General Partner determines that the Partnership is required to withhold or pay with respect to any amount distributable or allocable to such Limited Partner pursuant to this Agreement, including, without limitation, any taxes required to be withheld or paid by the Partnership pursuant to Sections 1441, 1442, 1445 or 1446 of the Code.

(b)Treatment of Amounts Withheld. Any amount paid on behalf of or with respect to a Limited Partner under Section 10.5(a) shall constitute a loan by the Partnership to such Limited Partner, which loan shall be repaid by such Limited Partner within fifteen (15) days after notice from the General Partner that such payment must be made unless:

(i)the Partnership withholds such payment from a distribution which would otherwise be made to the Limited Partner; or

(ii)the General Partner determines, in its sole and absolute discretion, that such payment may be satisfied out of the available funds of the Partnership which would, but for such payment, be distributed to the Limited Partner.

Any amounts withheld from amounts otherwise distributable to a Limited Partner as described in clause (i) or (ii) of this Section 10.5(b) shall be treated as having been distributed to such Limited Partner.

(c)Security Interest. Each Limited Partner hereby unconditionally and irrevocably grants to the Partnership a security interest in such Limited Partner’s Partnership Interest to secure such Limited Partner’s obligation to pay to the Partnership any amounts required to be paid pursuant to this Section 10.5. Each Limited Partner shall take such actions as the Partnership or the General Partner shall request in order to perfect or enforce the security interest created hereunder.

(d)Default. In the event that a Limited Partner fails to pay when due any amounts owed to the Partnership pursuant to this Section 10.5, the General Partner may, in its sole and absolute discretion, elect to make the payment to the Partnership on behalf of such defaulting Limited Partner, and in such event shall be deemed to have loaned such amount to such defaulting Limited Partner and shall succeed to all rights and remedies of the Partnership as against such defaulting Limited Partner. Without limitation, in such event, the General Partner shall have the right to receive distributions that would otherwise be distributable to such defaulting Limited Partner until such time as such loan, together with all interest thereon, has been paid in full, and any such distributions so received by the General Partner shall be treated as

having been distributed to the defaulting Limited Partner and immediately paid by the defaulting Limited Partner to the General Partner in repayment of such loan.

(e)Interest. Any amount payable by a Limited Partner under this Section 10.5 shall bear interest at the lesser of (i) the base rate on corporate loans at large United States money center commercial banks, as published from time to time in The Wall Street Journal, plus four (4) percentage points, and (ii) the maximum lawful rate of interest on such obligation, such interest to accrue from the date such amount is due (i.e., fifteen (15) days after demand) until such amount is paid in full.

11.Transfers and Withdrawals.

11.1Restrictions on Transfer. No Partnership Interest shall be Transferred, in whole or in part, except in accordance with the terms and conditions set forth in this Section 11. Any Transfer or purported Transfer of a Partnership Interest not made in accordance with this Section 11 shall be null and void.

11.2Transfer of the General Partner’s General Partner Interest.

(a)The General Partner may not Transfer any of its General Partner Interest or withdraw as General Partner, except as provided in or in connection with a transaction contemplated by Section 11.2(b), (c) or (d).

(b)Except as otherwise provided in Section 11.2(c) or (d) hereof, the General Partner shall not engage in any merger, consolidation or other combination with or into another Person or sale of all or substantially all of its assets, (other than in connection with a change in the General Partner’s state of incorporation or organizational form) in each case which results in a Change of Control (a “Transaction”), unless:

(i)the Consent of a Majority In Interest is obtained;

(ii)as a result of such Transaction all Limited Partners will receive for each Partnership Unit an amount of cash, securities, or other property equal to the greatest amount of cash, securities or other property paid in the Transaction to a holder of one share of membership interests of the General Partner (Class I Common Stock in the event AHR is the General Partner) in consideration of one shares of common stock, provided that if, in connection with the Transaction, a purchase, tender or exchange offer (“Offer”) shall have been made to and accepted by the holders of more than 50% of the outstanding membership interests of the General Partner (Class I Common Stock in the event AHR is the General Partner), each holder of a Partnership Units shall be given the option to exchange its Partnership Units for the greatest amount of cash, securities, or other property which a Limited Partner would have received had it (A) exercised its Redemption Right and (B) sold, tendered or exchanged pursuant to the Offer the shares of common stock of AHR received upon exercise of the Redemption Right immediately prior to the expiration of the Offer; or

(iii)AHR is the surviving entity in the Transaction and either (A) the holders of shares of AHR’s common stock do not receive cash, securities, or other property in the Transaction or (B) all Limited Partners (other than the General Partner, AHR or any

Subsidiary of AHR) receive an amount of cash, securities, or other property (expressed as an amount per share of common stock) that is no less than the product of the Conversion Factor and the greatest amount of cash, securities, or other property (expressed as an amount per shares of common stock) received in the Transaction by any holder of shares of common stock of AHR.

(c)Notwithstanding Section 11.2(b), AHR may merge with or into or consolidate with another Entity if immediately after such merger or consolidation (i) substantially all of the assets of the Successor Entity, other than Partnership Units held by the General Partner, are contributed, directly or indirectly, to the Partnership as a Capital Contribution in exchange for Partnership Units with a fair market value equal to the value of the assets so contributed as determined by the Successor Entity in good faith and (ii) the Successor Entity expressly agrees to assume all obligations of the General Partner, as appropriate, hereunder. Upon such contribution and assumption, the Successor Entity shall have the right and duty to amend this Agreement as set forth in this Section 11.2(c). The Successor Entity shall in good faith amend this Agreement to arrive at a new method for the calculation of the Cash Amount, the REIT Stock Amount and Conversion Factor for a Partnership Unit after any such merger or consolidation so as to approximate the existing method for such calculation as closely as reasonably possible. Such calculation shall take into account, among other things, the kind and amount of securities, cash and other property that was receivable upon such merger or consolidation by a holder of common stock of AHR or options, warrants or other rights relating thereto, and which a holder of Partnership Units could have acquired had such Partnership Units been exchanged immediately prior to such merger or consolidation. Such amendment to this Agreement shall provide for adjustment to such method of calculation, which shall be as nearly equivalent as may be practicable to the adjustments provided for with respect to the Conversion Factor. The Successor Entity also shall in good faith modify the definition of REIT Stock and make such amendments to Section 8.6 hereof so as to approximate the existing rights and obligations set forth in Section 8.6 as closely as reasonably possible. The above provisions of this Section 11.2(c) shall similarly apply to successive mergers or consolidations permitted hereunder.

(d)Notwithstanding Section 11.2(b),

(i)a General Partner may Transfer all or any portion of its General Partnership Interest to (A) a wholly owned Subsidiary of such General Partner or (B) the owner of all of the ownership interests of such General Partner, and following a Transfer of all of its General Partnership Interest, may withdraw as General Partner; and

(ii)the General Partner may engage in Transactions not required by law or by the rules of any national securities exchange on which shares of the General Partner’s common stock are listed to be submitted to the vote of the holders of common stock of the General Partner.

11.3Limited Partners’ Rights to Transfer.

(a)General. Subject to the provisions of Section 11.3(b) and Section 11.3(g), no Limited Partner shall have the right to Transfer all or a portion of such Limited Partner’s Partnership Interest, or any of such Limited Partner’s rights as a Limited Partner, without the

consent of the General Partner, which may be given or withheld by the General Partner in its sole and absolute discretion.

(b)Transfers to Permitted Transferees. Notwithstanding the provisions of Section 11.3(a), but subject to the provisions of Sections 11.3(c), 11.3(d) and 11.3(e) and other applicable restrictions on Transfers contained in this Section 11, a Limited Partner may Transfer, with or without the consent of the General Partner, all or a portion of his Partnership Units to a Permitted Transferee; provided that such Permitted Transferee must qualify as an “accredited investor” as such term is defined in Rule 501(a) of Regulation D promulgated under the Securities Act; and provided further that no Transfer pursuant to this Section 11.3(b) shall be effective until the General Partner receives notice of such Transfer.

(c)No Transfers Violating Securities Laws. The General Partner may prohibit any Transfer by a Limited Partner of its Partnership Units if, in the opinion of legal counsel to the Partnership, such Transfer would require the filing of a registration statement under the Securities Act, or would otherwise violate any federal or state securities laws or regulations applicable to the Partnership or the Partnership Units.

(d)No Transfers to Certain Lenders. No Transfer of any Partnership Units may be made to a lender to the Partnership or any Person who is related (within the meaning of Treasury Regulations Section 1.752-4(b)) to any lender to the Partnership whose loan constitutes a nonrecourse liability (within the meaning of Treasury Regulations Section 1.752-1(a)(2)), without the consent of the General Partner, which may be withheld in its sole and absolute discretion.

(e)Additional Prohibited Transfers. No Transfer by a Limited Partner of its Partnership Units may be made to any Person if:

(i)in the opinion the General Partner based on the advice of legal counsel, if appropriate, it would adversely affect the ability of the General Partner to continue to qualify as a REIT or would subject the General Partner to any additional taxes under Sections 857 or 4981 of the Code;

(ii)in the opinion of the General Partner based on the advice of legal counsel, if appropriate, it would result in the Partnership being treated as an association taxable as a corporation for federal income tax purposes;

(iii)such Transfer would subject the Partnership, the General Partner, or the Advisor to regulation under the Investment Company Act of 1940, as amended, the Investment Advisers Act of 1940, as amended, or ERISA;

(iv)such Transfer is effectuated through an “established securities market” or a “secondary market (or the substantial equivalent thereof)” within the meaning of Section 7704 of the Code; or

(v)such Transfer is to a Prohibited Transferee.

(f)Incapacitated Limited Partners. If a Limited Partner is Incapacitated, the executor, administrator, trustee, committee, guardian, conservator or receiver of such Limited Partner’s estate shall have all of the rights of a Limited Partner, but not more rights than those enjoyed by other Limited Partners, for the purpose of settling or managing the estate and such power as the Incapacitated Limited Partner possessed to Transfer all or any part of his or its interest in the Partnership. The Incapacity of a Limited Partner, in and of itself, shall not dissolve or terminate the Partnership.

(g)AHI Contributor Lock-Up. Notwithstanding anything herein to the contrary, other than Transfers to Permitted Transferees in compliance with Sections 11.3(b), 11.3(c), 11.3(d) and 11.3(e), no Partnership Unit issued in connection with the AHI Platform Acquisition may be Transferred until the end of the AHI Contributor Lock-Up Period, and, upon the Listing Date, Partnership Units issued in connection with the AHI Platform Acquisition may be subject to further customary restrictions on redemption (for a period not to exceed 180 days) to the extent required by the underwriters or investment bankers engaged by the General Partner or AHR in connection with the Listing Event.

11.4Substituted Limited Partners.

(a)Consent of the General Partner. No Limited Partner shall have the right to substitute a Permitted Transferee in such Limited Partner’s place. The General Partner shall, however, have the right to consent to the admission of a Permitted Transferee of the Partnership Interest of a Limited Partner pursuant to this Section 11.4 as a Substitute Limited Partner, which consent may be given or withheld by the General Partner in its sole and absolute discretion. The General Partner’s failure or refusal to permit such transferee to become a Substituted Limited Partner shall not give rise to any cause of action against the Partnership or any Partner. Notwithstanding the foregoing, Limited Partners who were issued Partnership Units in connection with the AHI Platform Acquisition shall have the right to substitute a Permitted Transferee in such Limited Partner’s place assuming compliance with Sections 11.3(b), 11.3(c), 11.3(d) and 11.3(e).

(b)Rights of a Substituted Limited Partner. A transferee who has been admitted as a Substituted Limited Partner in accordance with this Section 11 shall have all the rights and powers and be subject to all the restrictions and liabilities of a Limited Partner under this Agreement. The admission of any transferee as a Substituted Limited Partner shall be conditioned upon the transferee executing and delivering to the Partnership an acceptance of all of the terms and conditions of this Agreement, including, without limitation, the power of attorney granted in Section 2.6, and such other documents or instruments as may be required in the reasonable discretion of the General Partner in order to effect such Person’s admission as a Substituted Limited Partner.

(c)Amendments to Exhibit A. Upon the admission of a Substituted Limited Partner, the General Partner shall amend Exhibit A to reflect the name, address, number of Partnership Units, and Percentage Interest of such Substituted Limited Partner and to eliminate or adjust, if necessary, the name, address and interest of the predecessor of such Substituted Limited Partner.

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

11.6General Provisions.

(a)Withdrawal of a Limited Partner. No Limited Partner may withdraw from the Partnership other than as a result of a Transfer of all of such Limited Partner’s Partnership Units pursuant to which the transferee is admitted as a Substituted Limited Partner or a redemption of all of the Partnership Units held by such Limited Partner pursuant to Section 8.6.

(b)Termination of Status as a Limited Partner. Any Limited Partner that (i) Transfers all of such Limited Partner’s Partnership Units (or other Partnership Interests) in a Transfer pursuant to which the transferee is admitted as a Substituted Limited Partner, or (ii) redeems all of such the Partnership Units held by such Limited Partner pursuant to Section 8.6 shall cease to be a Limited Partner.

(c)Allocations. If any Partnership Interest is Transferred during the Partnership’s Fiscal Year in compliance with the provisions of this Section 11 (including Transfers to the General Partner pursuant to Section 8.6(c)) on any day other than the first day of a Fiscal Year, then Profit, Losses, each item thereof and all other items attributable to such Partnership Interest for such Fiscal Year shall be divided and allocated between the transferor Partner and the transferee Partner by taking into account their varying interests during the Fiscal Year in accordance with Section 706(d) of the Code, using the interim closing of the books method (unless the General Partner, in its sole and absolute discretion, elects to adopt a daily, weekly or monthly proration period, in which event Profits, Losses, each item thereof and all other items attributable to such transferred Partnership Interest for such Fiscal Year shall be prorated based upon the applicable method selected by the General Partner).

(d)Distributions. All distributions of cash or other Partnership Assets attributable to Partnership Units, with respect to which the Partnership Record Date is before the date of a Transfer of such Partnership Units (including any Transfer to the General Partner pursuant to Section 8.6(c)), shall be made to the transferor Partner, and all distributions of cash or other Partnership Assets thereafter attributable to such Partnership Units shall be made to the transferee Partner (or Assignee).

(e)Capital Accounts. The original Capital Account established for each transferee shall be in the same amount as the Capital Account or portion thereof of the Partner or Assignee to which such transferee succeeds, at the time of such Transfer. The Capital Account of any Partner whose Percentage Interest shall be increased by means of the Transfer to it of all or part of the Partnership Interest of another Partner shall be appropriately adjusted to reflect such Transfer. Any reference in this Agreement to a Capital Contribution of, or distribution to, a then-Partner shall include a Capital Contribution or distribution previously made by or to any prior Partner on account of the Partnership Interest of such then-Partner.

(f)Additional Restrictions. In addition to any other restrictions on Transfer contained in this Agreement, in no event may any Transfer of a Partnership Interest by any Partner or any redemption pursuant to Section 8.6 be made without the express consent of the General Partner, in its sole and absolute discretion, (i) to any person or Entity who lacks the legal right, power or capacity to own a Partnership Interest; (ii) in violation of applicable law; (iii) of any component portion of a Partnership Interest, such as the Capital Account, or rights to distributions, separate and apart from all other components of a Partnership Interest; (iv) if in the opinion of the General Partner based on the advice of legal counsel, if appropriate, such Transfer would cause a termination of the Partnership for federal or state income tax purposes (except as a result of a redemption of all Partnership Units held by all Limited Partners); (v) if in the opinion of the General Partner based on the advice of legal counsel, if appropriate, such Transfer would cause the Partnership to cease to be classified as a partnership for federal income tax purposes (except as a result of a redemption of all Partnership Units held by all Limited Partners); (vi) if such Transfer requires the registration of such Partnership Interest pursuant to any applicable federal or state securities laws; (vii) if such Transfer would cause the Partnership to become a “publicly traded partnership,” as such term is defined in Section 7704(b) of the Code (provided that this clause (vii) shall not be the basis for limiting or restricting in any manner the exercise of the Redemption Right under Section 8.6 unless, and only to the extent that, outside tax counsel advises the General Partner that, in the absence of such limitation or restriction, there is a significant risk that the Partnership will be treated as a “publicly traded partnership” and, by reason thereof, taxable as a corporation); (viii) if such Transfer would cause the General Partner to own 10% or more of the ownership interests of any tenant of a property held by the Partnership within the meaning of Section 856(d)(2)(B) of the Code; (ix) if such Transfer would result in AHR being “closely held” within the meaning of Section 856(h) of the Code; or (x) if in the opinion of the General Partner based on the advice of legal counsel, if appropriate, such Transfer would adversely affect the ability of AHR to continue to qualify as a REIT or subject the General Partner or AHR to any additional taxes under Sections 857 or 4981 of the Code.

(g)Exchange, Reclassification, or Redesignation of REIT Stock. If AHR exchanges, reclassifies, or redesignates any shares of REIT Stock of any class (“Exchanged REIT Stock”) for shares of REIT Stock of a different class (“Received REIT Stock”), then the General Partner shall, and shall cause the Partnership to, exchange, reclassify, or redesignate a number of Partnership Units having the same class designation as the Exchanged REIT Stock, for Partnership Units having the same class designation as the Received REIT Stock on the same terms, to the extent applicable, that AHR exchanged, reclassified, or redesignated the Exchanged REIT Stock. Such exchange, reclassification, or redesignation of Partnership Units shall occur automatically after the close of business on the applicable date of the exchange, reclassification, or redesignation of shares of REIT Stock, as of which time the holder of class of Partnership

Units having the same designation as the Exchanged REIT Stock shall be credited on the books and records of the Partnership with the issuance, as of the opening of business on the next day, of the applicable number of Partnership Units having the same designation as the Received REIT Stock.

12.Admission of Partners.

12.1Admission of Successor General Partner. A successor to all of the General Partner Interest pursuant to Section 11 hereof who is proposed to be admitted as a successor General Partner shall be admitted to the Partnership as the General Partner, effective immediately following the successor General Partner’s execution and delivery to the Partnership of an acceptance of all of the terms and conditions of this Agreement and such other documents or instruments as may be required or appropriate to effect such Person’s admission as General Partner. In the case of such admission on any day other than the first day of a Fiscal Year, all items attributable to the General Partner Interest for such Fiscal Year shall be allocated between the transferring General Partner and such successor as provided in Section 11.6(c) hereof. Any such successor General Partner shall carry on the business of the Partnership without dissolution.

12.2Admission of Additional Limited Partners.

(a)General. A Person other than the General Partner who makes a Capital Contribution to the Partnership in accordance with this Agreement shall be admitted to the Partnership as an Additional Limited Partner only upon executing and delivering to the General Partner:

(i)evidence of acceptance in form satisfactory to the General Partner of all of the terms and conditions of this Agreement, including, without limitation, the power of attorney granted in Section 2.6 hereof; and

(ii)such other documents or instruments as may be required in the discretion of the General Partner in order to effect such Person’s admission as an Additional Limited Partner.

(b)General Partner’s Consent Required. Notwithstanding anything to the contrary in this Section 12.2, no Person shall be admitted as an Additional Limited Partner without the consent of the General Partner, which consent may be given or withheld in the General Partner’s sole and absolute discretion. The admission of any Person as an Additional Limited Partner shall become effective on the date upon which the name of such Person is recorded on the books and records of the Partnership, following the consent of the General Partner to such admission and the satisfaction of the conditions set forth in Section 12.2(a).

(c)Allocations to Additional Limited Partners. If any Additional Limited Partner is admitted to the Partnership on any day other than the first day of a Fiscal Year, then Profit, Losses, each item thereof and all other items allocable among Partners and Assignees for such Fiscal Year shall be allocated among such Additional Limited Partner and all other Partners and Assignees by taking into account their varying interests during the Fiscal Year in accordance with Section 706(d) of the Code, using the interim closing of the books method. Solely for purposes of making such allocations, each of such items for the calendar month in which an

admission of any Additional Limited Partner occurs shall be allocated among all of the Partners and Assignees, including such Additional Limited Partner.

12.3Amendment of Agreement and Certificate of Limited Partnership. For the admission to the Partnership of any Partner, the General Partner shall take all steps necessary and appropriate under the Act to amend the records of the Partnership and, if necessary, to prepare as soon as practical an amendment of this Agreement (including an amendment of Exhibit A) and, if required by law, shall prepare and file an amendment to the Certificate and may for this purpose exercise the power of attorney granted pursuant to Section 2.6 hereof.

13.Dissolution, Liquidation and Termination.

13.1Dissolution. The Partnership shall not be dissolved by the admission of Substituted Limited Partners or Additional Limited Partners or by the admission of a successor General Partner in accordance with the terms of this Agreement. Subject to Section 13.1(b), upon the withdrawal of the General Partner, any successor General Partner shall continue the business of the Partnership without dissolution. The Partnership shall dissolve, and its affairs shall be wound up, only upon the first to occur of any of the following (each, a “Liquidating Event”):

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

(b)an event of withdrawal of the General Partner, as defined in the Act (other than an event of bankruptcy), unless, within ninety (90) days after such event of withdrawal, a Majority In Interest Consent in writing to continue the business of the Partnership and to the appointment, effective as of the date of withdrawal, of a successor General Partner;

(c)an election to dissolve the Partnership made by the General Partner, in its sole and absolute discretion;

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

(e)the occurrence of a Terminating Sale Transaction; or

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

13.2Winding Up; Liquidation.

(a)Upon dissolution of the Partnership, the business and affairs of the Partnership shall be wound up as provided in this Section 13.2. The General Partner shall act as the “Liquidator” (or, in the event there is no remaining General Partner, any Person elected by

Limited Partners holding more than 50% of the total number of Partnership Units then issued and outstanding). The Liquidator shall wind up the affairs of the Partnership, shall dispose of such Partnership Assets as it deems necessary or appropriate and shall pay and distribute the assets of the Partnership, including the proceeds of any such disposition, as follows:

(i)first, to creditors, including Partners who are creditors, to the extent otherwise permitted by law, in satisfaction of liabilities of the Partnership (whether by payment or by establishment or reserves as determined by the Liquidator in its sole discretion), other than distributions to Partners pursuant to Section 5, and

(ii)second, to the Partners in accordance with their positive Capital Account balances.

It is intended that such distributions will result in the Partners receiving aggregate distributions in the order of and equal to the amount of distributions that would have been received if the liquidating distributions were made in accordance with Section 5.1. However, if the balances in the Capital Accounts do not result in such intention being satisfied, items of Profits and Losses will be reallocated among the Partners for the Fiscal Year of the liquidation (and, at the election of the General Partner, if necessary and permissible, prior Fiscal Years) so as to cause the balances in the Capital Accounts to be in the amounts necessary to assure that such result is achieved. Notwithstanding anything herein to the contrary, in the event the Partnership is liquidated within the meaning of Treasury Regulation Section 1.704-1(b)(2)(ii)(g), liquidation distributions shall be made by the end of the taxable year in which the Partnership liquidates or, if later, within ninety (90) days of the date of such liquidation.

(b)In the discretion of the Liquidator, a pro rata portion of the distributions that would otherwise be made to the Partners pursuant to this Section 13 may be:

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

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

(c)The Liquidator shall, in its sole discretion, determine whether to sell any Partnership Assets, including, without limitation, Real Estate Assets, and if so, whether at a public or private sale, for what price and on what terms. If the Liquidator determines to sell or otherwise dispose of any Partnership Asset or any interest therein, the Liquidator shall do so

expeditiously and for its fair market value under the circumstances, giving due regard to the activity and condition of the relevant market and general financial and economic conditions. If the Liquidator determines not to sell or otherwise dispose of any Partnership Asset or any interest therein, the Liquidator shall not be required to distribute the same to the Partners promptly but shall have full right and discretion to determine the time and manner of such distribution and distributions giving due regard to the interests of the Partners.

13.3No Obligation to Contribute Deficit. If any Partner has a deficit balance in his Capital Account (after giving effect to all contributions, distributions and allocations for all taxable years, including the year during which such liquidation occurs), such 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.

13.4Notice of Dissolution. In the event a Liquidating Event occurs or an event occurs that would, but for the provisions of an election pursuant to Section 13.1, 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.

13.5Termination of Partnership and Cancellation of Certificate of Limited Partnership. Upon the completion of the liquidation of the Partnership’s assets, as provided in Section 13.2 hereof, the Partnership shall be terminated, a certificate of cancellation shall be filed, and all qualifications of the Partnership as a foreign limited partnership in jurisdictions other than the state of Delaware shall be canceled and such other actions as may be necessary to terminate the Partnership shall be taken.

13.6Reasonable Time for Winding-Up. A reasonable time shall be allowed for the orderly winding-up of the business and affairs of the Partnership and the liquidation of its assets pursuant to Section 13.2 hereof in order to minimize any losses otherwise attendant upon such winding-up, and the provisions of this Agreement shall remain in effect among the Partners during the period of liquidation.

13.7Waiver of Partition. Each Partner hereby waives any right to partition of the Partnership property.

14.Amendment of this Agreement; Meetings.

14.1Amendments.

(a)By the General Partner. The General Partner shall have the power, without the consent of the Limited Partners, to amend this Agreement except as set forth in Section 14.1(b) hereof. The General Partner shall provide notice to the Limited Partners when any action under this Section 14.1(a) is taken in the next regular communication to the Limited Partners. The Limited Partners shall not have the power to amend this Agreement.

(b)Restrictions on General Partner’s Ability to Amend this Agreement or the Certificate. Notwithstanding Section 14.1(a) hereof or any other provision of this Agreement,

neither this Agreement nor the Certificate shall be amended with respect to any Partner adversely affected without the Consent of such Partner adversely affected if such amendment would:

(i)convert a Limited Partner’s interest in the Partnership into a General Partner Interest;

(ii)impose on the Limited Partners any obligation to make additional Capital Contributions to the Partnership;

(iii)modify the limited liability of a Limited Partner in a manner adverse to such Limited Partner;

(iv)affect the Redemption Right of a Limited Partner in a manner adverse to such Limited Partner;

(vi)economically reduce the Partnership’s relative share of Profit and Loss to the Limited Partners, other than with respect to the issuance of additional Participating Partnership Units pursuant to Section 4.2; or

(vii)amend this Section 14.1(b).

14.2Meetings of the Partners.

(a)General. Meetings of the Partners may be called by the General Partner and shall be called upon the receipt by the General Partner of a written request by Limited Partners holding twenty-five percent (25%) or more of the Partnership Interests. The request shall state the nature of the business to be transacted. Notice of any such meeting shall be given to all Partners not less than seven (7) days nor more than thirty (30) days prior to the date of such meeting. Partners may vote in person or by proxy at such meeting.

(b)Vote Required. Whenever the vote or Consent of the Partners is permitted or required under this Agreement, such vote or Consent may be given at a meeting of the Partners or may be given in accordance with the procedure prescribed in Section 14.2(c) hereof. Except as otherwise expressly provided in this Agreement, the Consent of holders of Partnership Units that constitute more than fifty percent (50%) of the aggregate number of outstanding Partnership Units held by the Partners (including the General Partner) shall constitute the consent of the Partners.

(c)Action Without a Meeting. Any action required or permitted to be taken at a meeting of the Partners may be taken without a meeting if a written consent setting forth the action so taken is signed by the minimum number of holders of Partnership Units that would have been necessary to authorize or take such action at a meeting at which all holders of Partnership Units entitled to vote thereon were present and voted. Such consent may be in one instrument or in several instruments, and shall have the same force and effect as a vote the

holders of Partnership Units that constitute more than fifty percent (50%) (or such other percentage as is expressly required by this Agreement) of the aggregate number of outstanding Partnership Units held by the Partners and entitled to vote on the applicable action (including the General Partner). Such consent shall be filed with the General Partner. An action so taken shall be deemed to have been taken at a meeting held on the effective date of the consent as certified by the General Partner.

(d)Proxy. Each Partner may authorize any Person or Persons to act for him by proxy on all matters in which a 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 his attorney-in-fact and a copy thereof delivered to the Partnership. 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, such revocation to be effective upon the General Partner’s receipt of written notice of such revocation from the Partner executing such proxy.

(e)Conduct of Meeting. Each meeting of the Partners shall be conducted by the General Partner or such other Person as the General Partner may appoint pursuant to such rules for the conduct of the meeting as the General Partner or such other Person appointed by the General Partner deems appropriate. Meetings of Partners may be conducted in the same manner as meetings of the stockholders of the General Partner and may be held at the same time, and as part of, meetings of the stockholders of the General Partner.

15.General Provisions.
