     (a) In the case of a proposed Transfer of all or any portion of the Preferred Stock held by any Stockholder (other than a Transfer in accordance with Section 3.01(a)), each other Stockholder holding Preferred Stock may exercise tag-along rights (a “Tag-Along Transfer”) in accordance with the terms, conditions and procedures set forth herein (any Stockholder exercising such rights, a “Tagging Preferred Stockholder”).

     (b) After complying with the provisions of Section 3.02 hereof, the Transferring Stockholder shall promptly give notice (a “Tag-Along Notice”) to the Company and each other Stockholder holding Preferred Stock of any Tag-Along Transfer, setting forth the number of shares of Preferred Stock proposed to be Transferred, the name of the Transferee, the proposed amount and form of consideration for such shares of Preferred Stock, and any other material terms and conditions of the Tag-Along Transfer. Each other Stockholder holding Preferred Stock shall have a period of fifteen (15) days from the date of the Tag-Along Notice within which to elect by written notice to the Transferring Stockholder to sell up to its pro rata portion (determined by multiplying the number of shares of Preferred Stock proposed to be Transferred by a fraction the numerator of which is the amount of shares of Preferred Stock held by such Tagging Preferred Stockholder and the denominator of which is the aggregate number of shares of Preferred Stock held by the Tagging Preferred Stockholder and the other Stockholders electing to participate in the Tag-Along Transfer) of the shares of Preferred Stock that are subject to the underlying Transfer in connection with such Tag-Along Transfer. Any Stockholder holding shares of Preferred Stock may exercise such right by delivery of an irrevocable written notice to the Company and to the Transferring Stockholder specifying the number of shares of Preferred Stock such Stockholder desires to include in the Tag-Along Transfer. If the Transferring Stockholder is unable to cause the Transferee to purchase all of the shares of Preferred Stock proposed to be Transferred, then the Transferring Stockholder may (A) terminate the sale of the shares of Preferred Stock to the transferee and terminate such Tag-Along Transfer as to all Stockholders or (B) on behalf of all Stockholders, sell that agreed portion of each Tagging Preferred Stockholder’s shares of Preferred Stock that is equal to the product of (x) the total number of shares of Preferred Stock subject to the proposed

Tag-Along Transfer that the proposed Transferee is willing to purchase and (y) such Stockholder’s pro rata portion (determined by multiplying the number of shares of Preferred Stock proposed to be Transferred by a fraction the numerator of which is the number of shares of Preferred Stock held by such Tagging Preferred Stockholder and the denominator of which is the aggregate number of shares of Preferred Stock held by the Tagging Preferred Stockholder and the other Stockholders electing to participate in the Tag-Along Transfer). The Transferring Stockholder shall have a period of sixty (60) days following the expiration of the fifteen (15)-day period mentioned above to sell all of the shares of Preferred Stock agreed to be purchased by the Transferee, on the payment terms specified in the Tag-Along Notice.

     (c) Each Tagging Preferred Stockholder shall agree (i) to make such representations, warranties, covenants, indemnities and agreements to the transferee as made by the Transferring Stockholder in connection with the Tag-Along Transfer (other than any non-competition or similar agreements or covenants that would bind the Tagging Preferred Stockholder or its Affiliates), and (ii) to substantially the same terms and conditions to the Transfer as the Transferring Stockholder agrees. Notwithstanding the foregoing, however, all such representations, warranties, covenants, indemnities and agreements shall be made by each Tagging Preferred Stockholder severally and not jointly.

     Section 3.04 [Intentionally Omitted].

     Section 3.05 Rights and Obligations of Transferees and Transferors.

     (a) No Transferee (other than a Qualified Affiliate of a Stockholder) shall acquire any of the rights set forth in Sections 2.01(a), 2.02, 2.03, 2.04, 2.05 or Article III hereof by reason of the Transfer unless such Transferee purchases all (but not less than all) of the shares of Preferred Stock (and for the purposes of Sections 2.01(a), 2.02, 2.03, 2.04 and 2.05, all of the transferable membership units in Milagro Holdings, in accordance Section 7.05 of the Holdings Agreement) held by such Transferor as of the date of such Transfer, in which case all such rights (and any other rights of the Transferor) may be acquired by such Transferee. In the event that the Transferee (whether or not it is an existing Stockholder as of the date hereof) acquires such rights, it will be treated for all purposes under this Agreement as if it were the Transferor from whom such Transferee acquired such rights. For the avoidance of doubt, any Transferee that acquires all (but not less than all) of the Securities held by Acon, MI or West Coast, including such Transferor’s membership interest in Milagro Holdings, such Transferee shall be entitled to appoint the Acon Directors, West Coast Director or MI Director, as the case may be.

     (b) Any Transfer of Securities hereunder shall not release the party transferring such Securities from any liability or obligation it may have hereunder with respect to liabilities and obligations incurred prior to the date of such Transfer or with respect to Securities that it continues to own after the date of such Transfer.

     (b) Not later than one hundred and twenty (120) days after the end of each Fiscal Year, the Company shall prepare or cause to be prepared, and shall mail to each Stockholder, an audited report setting forth at the end of such Fiscal Year the following: a balance sheet of the Company; an income statement of the Company; and a statement of changes in cash flow of the Company.

Any Person purchasing or otherwise acquiring any direct or indirect interest in any equity securities of the Company shall be deemed to have notice of and consent to the provisions of this Article V.

     Section 6.07 Waivers. No waiver of any breach of any of the terms of this Agreement shall be effective unless such waiver is made expressly in writing and executed and delivered by the party against whom such waiver is claimed. No waiver of any breach shall be deemed to be a further or continuing waiver of such breach or a waiver of any other or subsequent breach. Except as otherwise expressly provided herein, no failure on the part of any party to exercise,

and no delay in exercising, any right, power or remedy hereunder, or otherwise available in respect hereof at law or in equity, shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof, or the exercise of any other right, power or remedy.

     Section 6.13 Specific Performance. It is hereby agreed and acknowledged that it will be impossible to measure in money the damages that would be suffered if the parties fail to comply with any of the obligations herein imposed on them and that, in the event of any such failure, an aggrieved Person will be irreparably damaged and will not have an adequate remedy at law.
