STATEMENT OF AGREEMENT

NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein and for other good, valuable and binding consideration, the receipt sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound hereby, agree as follows:

ARTICLE I

RESTRICTIONS AGAINST TRANSFER

Assignee agrees that it will not under any circumstances transfer, assign, pledge, hypothecate, encumber or in any way alienate any of the Partnership Interests, or any right or interest therein, whether voluntarily or by operation of law, or by gift or otherwise, except pursuant to the provisions of this Agreement.

ARTICLE II

TRANSFERS

Assignee shall be allowed to transfer all or any portion of its Partnership Interests to any Affiliate or another Limited Partner (as such terms are defined in the Partnership Agreement) without the consent of the General Partner. Any other transfer shall require the consent of the General Partner, which consent may be given or withheld in the sole discretion of the General Partner.

ARTICLE III

REPURCHASE OF SHARES BY WESTON

Competition. Until                     , Weston shall have the right to purchase, at the Purchase Price (as defined below), any Partnership Interests now owned or hereafter acquired by Assignee if Assignee engages in Competition as defined below. Assignee agrees to notify Weston in writing of each employer of Assignee and each person and entity to whom Assignee provides services for compensation from and after the date hereof until the earlier of                      or so long as Assignee or any of Assignee’s transferees hold or has any interest in any Partnership Interests.

Purchase Price. The “Purchase Price” for the Partnership Interests shall be determined by reference to the value of the Assignee’s Partnership Interest on the date the notice of exercise is given pursuant to paragraph (c) of this Article III. The Purchase Price shall be equal to (i) the Per-Share Appraised Value of Macro Holding, Inc. (as defined below) multiplied by the number of shares of Macro Holding, Inc. held by the Partnership, minus any liabilities of the Partnership, multiplied by (ii) the Assignee’s ownership interest percentage in the Partnership,. The “Per-Share Appraised Value of Macro Holding, Inc.” shall be the value of one share of the common stock of Macro Holding, Inc., as determined by the most recent completed and delivered regularly scheduled annual or quarterly appraisal thereof as of the date notice of exercise is given pursuant to paragraph (c) of this Article III, proportionately adjusted for any stock dividends, stock splits, combinations and recapitalizations.

Exercise of Right. If Weston desires to exercise its right to purchase such Partnership Interests, it shall within 30 days after the date Weston determines that Assignee engages in Competition, (i) deliver a notice of exercise to Assignee, and (ii) make available at the offices of the Company, a check in the amount of the purchase price for the Partnership Interests. If Weston makes the consideration available, at the time and place and in the amount and form provided for in this Article 3 for the Partnership Interests to be purchased pursuant to Weston’s repurchase rights, then after such time the person from whom such Partnership Interests are to be purchased shall no longer have any rights as a holder of the Partnership Interests (other than the right to receive payment of such consideration as set forth herein). Such Partnership Interests shall be deemed to have been purchased in accordance with the applicable provisions hereof, whether or not the certificate(s) therefor have been delivered as required by this Article 3.

(d) Competition. For purposes hereof, the term “Competition” shall include, without limitation, (i) Assignee providing services to a competitor of Macro Holding, Inc. or any parent, subsidiary or affiliated entity (collectively, the “Company”), whether as an employee, officer, director, independent contractor, consultant, agent or otherwise, (ii) Assignee lending to or making an investment in any such competitor, or (iii) Assignee competing with the products or services of the Company, in each case, such determination to be made in the reasonable discretion of Weston.
