OTHER AGREEMENTS

3.1 Notice of Certain REIT Actions. The REIT shall provide reasonable advance notice to the Board and the LG Investor prior to taking any of the following actions:

(a) disposing or permitting any of its Subsidiaries (including Aviv Healthcare Properties Limited Partnership or its Subsidiaries) to dispose of any United States real property interest (as defined in Section 897 of the Code) that would result in an allocation of taxable gain to the REIT (taking into account any adjustment under Section 743(b) of the Code attributable to the REIT);

(b) designating any dividend declared or paid by the REIT as a “capital gain dividend” (within the meaning of Section 857(b)(3)(C) of the Code), designating any amount pursuant to Section 857(b)(3)(D) of the Code or taking any other action that would reasonably be expected to cause a dividend paid or deemed paid by the REIT to be treated as a capital gain dividend (within the meaning of Section 857(b)(3)(C) of the Code) or otherwise cause the stockholders of the REIT to receive income that is considered effectively connected to the conduct of a U.S. trade or business for federal income tax purposes; or

(c) granting or permitting Aviv Healthcare Properties Limited Partnership or its Subsidiaries to give an option to purchase any property or assets of the REIT or any of its Subsidiaries, unless the REIT or applicable Subsidiary shall have the right to structure the transfer, and to delay the transfer pending the ability to effect such structure, of such property or assets upon exercise of such option as an exchange (rather than a purchase and sale) of all or a portion of such property or assets for other property or properties of like kind with value not less than the value of such property or assets in one or more concurrent or delayed fully tax-deferred exchanges which shall qualify under Section 1031(a) of the Code.

3.2 Interests in Tenants. Prior to entering into a tenant relationship with any third party that is not an existing tenant of the REIT, the REIT shall provide notice to the LG Investor of such intent and the LG Investor shall promptly respond to such notice by confirming to the REIT whether the LG Investor or any of its Affiliates owns an interest in such tenant. If the LG Investor or any of its Affiliates intends to acquire an interest in a party that it reasonably believes could be a tenant of the REIT that would otherwise result in a conflict with this Section 3.2, the LG Investor may provide notice the REIT of such intent and the REIT shall promptly respond to such notice by confirming to the LG Investor whether the REIT has an existing tenant relationship with such party.

3.3 Ownership Limit Waiver.

(a) LG Excepted Holder Limit. The application of the Ownership Limit pursuant to Section 7.2.1(a)(i) of the Charter is hereby waived for the sole and limited purpose of permitting Lindsay Goldberg to actually, Beneficially and Constructively Own up to 21,653,813.45 shares of Common Stock, which shall be proportionately adjusted in the event of any stock split, stock dividend or similar transaction.

(b) With the exception of the waiver set forth in Section 3.3(a), this Agreement does not waive any of the other restrictions or limitations set forth in Article VII of the Charter as they apply to the Common Stock or shares of Capital Stock actually owned, Beneficially Owned or Constructively Owned by Lindsay Goldberg, and does not apply to any other Person, including any Person that is a Beneficial or Constructive Owner of Common Stock or Shares of Capital Stock actually owned by the LG Investor.

3.4 Exclusive Purchase Opportunity.

(a) Except as set forth in Section 3.4(b), if the ownership, Beneficial Ownership, Constructive Ownership or Transfer of any shares of Common Stock held by Lindsay Goldberg causes or would cause (1) Lindsay Goldberg to Constructively Own shares of Common Stock in excess of the Excepted Holder Limit or (2) a violation of any of Sections 7.2.1(a)(i), (ii) or (iii) of the Charter, then as of the time of the occurrence of any of the foregoing events (even if discovered thereafter), the provisions of the Charter shall apply. Notwithstanding the foregoing, pursuant to Section 7.3.4 of the Charter, the REIT agrees that if the shares of Common Stock held by Lindsay Goldberg are deemed transferred to a trust pursuant to Section 7.2.1(b) and Section 7.3.1 of the Charter, the Person that held the shares Common Stock immediately prior to their transfer to the trust (the “Transferor”) will have an exclusive opportunity (the “Exclusive Purchase Opportunity”), subject to the requirements set forth herein, to repurchase such shares of Common Stock from the trust for a 90-day period beginning on the date the REIT gives the Transferor notice of the deemed transfer (which notice shall describe the reason that such shares of Common Stock were transferred to the trust with specificity so as to enable the Transferor to attempt to resolve such issue). In order to repurchase such shares of Common Stock, the Transferor will be required to (i) pay the trust the Market Price of such shares of Common Stock as of the time they are repurchased, as determined solely by the trustee of the trust and (ii) demonstrate to the trustee’s and the REIT’s satisfaction (which may, in the discretion of the trustee or the REIT, include an opinion of counsel selected by the trustee or the REIT) that the tax qualification issues that gave rise to the deemed transfer of the shares of Common Stock into the trust have been resolved so that the Transferor can reacquire the shares of Common Stock held in trust without such repurchase resulting in a deemed transfer back to the trust in accordance with the terms of the Charter. The trustee shall have the sole right to determine the Market Price of the shares of Common Stock as of the date of the deemed transfer to the trust, the date of the repurchase of such shares of Common Stock from the trust and any other relevant point in time, provided that the trustee shall make such Market Price determinations in the manner described in the definition of “Market Price” in Section 7.1 of the

5

Charter. For the avoidance of doubt, the trustee will be able to entertain expressions of interest from and discuss pricing and other terms with potential third party buyers during the 90-day period. If the Transferor does not repurchase the shares of Common Stock pursuant to the Exclusive Purchase Opportunity, the trustee will sell the shares of Common Stock to one or more Persons pursuant to Section 7.3.4 of the Charter.

(b) If the Transferor successfully repurchases such shares of Common Stock pursuant to the Exclusive Repurchase Opportunity, the Transferor will be permitted to net against the purchase price paid for such repurchase the amount that the Transferor would otherwise be entitled to receive from the trust under Section 7.3.4 of the Charter. For the avoidance of doubt, nothing in this Section 3.4 will alter the application of Sections 7.3.2 and 7.3.3 of the Charter to any of the shares of Common Stock deemed transferred to a trust.

ARTICLE 4

4.1 Voting by Lindsay Goldberg. In connection with any merger to which the REIT is a constituent party, a sale of all or substantially all of the assets of the REIT, plans of liquidation involving the REIT, or issuances of capital stock by the REIT, in each case, to the extent submitted to a vote of stockholders or included in a consent solicitation of the stockholders, Lindsay Goldberg shall be entitled to vote the product of (x) the number of shares of Common Stock that it owns, directly or indirectly, multiplied by (y) the percentage of Partnership Interests owned by the REIT in its sole and absolute discretion, and shall vote the remainder of its shares of Common Stock in excess of such amount in the same proportion as the votes cast by the Unaffiliated Stockholders.
