The Members acknowledge that Acacia is a public company and has disclosure obligations relating to its investment in the Company. The Senior Members hereby consent to the disclosure by each Member of Company information to such Member's accountants, attorneys and similar advisors bound by a duty of confidentiality; moreover, the foregoing requirements of this Section 3.3 shall not apply to a Member with regard to any information that becomes publicly known or available in the absence of any improper or unlawful action on the part of such Member (including, without limitation, any action in violation of this Section 3.3). 3.4 DISCLOSURES - Each Member shall furnish any data with respect to itself reasonably required in connection with the formation, operation or dissolution of the Company. ARTICLE IV RIGHTS AND DUTIES OF MEMBERS 4.1 MANAGEMENT RIGHTS OF SENIOR MEMBERS - All Senior Members (other than Assignees) shall be entitled to vote on any matter submitted to a vote of the Members. In order for the following actions to be taken (other than any of such actions which are reasonably required to effect, and are directly related to, the issuance of Membership Interests in connection with a Strategic Transaction prior to the Trigger Date and the admission of the Strategic Investor as a Member), a Supermajority of the Senior Members must consent thereto: (a) amending this Agreement; or (b) continuing the Company after a Dissolution Event; or (c) admitting Additional Members; or (d) selling (i) all or substantially all of Company Property not in the ordinary course of the Company's business, or (ii) any or all of the Company's right, title and interest in and to the Patents (other than the licensing of the Patents in the ordinary course of the Company's business on terms fair and reasonable to the Company); or (e) merging, consolidating, liquidating, winding-up or dissolving the Company; or 9 (f) entering into, by the Company, of any transaction with any of its or any Affiliates' managers, officers, directors, employees or Affiliates except under terms no less favorable than the terms of such a transaction with an unrelated third party, or except as expressly contemplated by this Agreement; or (g) the issuance of any equity of the Company ("Equity"), including Equity issued upon the conversion of any bonds, debentures or other securities of the Company and fixing the consideration to be received by the Company for the issuance of Equity; or (h) the issuance of any options, warrants or rights to purchase or otherwise acquire Equity; or (i) entering into any transaction or series of related transactions involving an aggregate amount to be paid or received by the Company in excess of $250,000 unless pursuant to the Budget and unless such transaction(s) are contemplated by such budget to occur within one year from the date of this Agreement; or (j) any equity split or recapitalization of the Company. 4.2 MANAGEMENT RIGHTS OF REGULAR MEMBERS - Regular Members shall have no right to participate in the management of the Company or to vote on any matter submitted to the Members for their consent. 4.3 LIABILITY OF MEMBERS - No Member shall be liable as such for the liabilities of the Company. The failure of a limited liability company to observe any formalities or requirements relating to the exercise of its powers or management of its business or affairs under this Agreement or the Act shall not be grounds for imposing personal liability on the Members for liabilities of this Company. 4.4 INDEMNIFICATION - In the absence of fraud, material breach of fiduciary duty, willful violation of this Agreement, or other willful misconduct on the part of a Member (which malfeasance shall have given rise to the matter at issue), the Company shall indemnify and hold each Member harmless from and against any loss, expense, damage or injury suffered or sustained by any of them by reason of any acts, omissions, or alleged acts or omissions arising out of any activity performed or not performed by, for, on behalf of, or otherwise related to the interests of the Company. This indemnification shall include, but not be limited to, (i) payment of reasonable attorneys' fees and other expenses incurred in settling any claim or threatened action (where such settlement is approved by counsel to the Company) or in connection with any legal proceeding, and (ii) the removal of any liens affecting the property of a Member. 10 4.5 REPRESENTATIONS AND WARRANTIES - Each Member, and, in the case of an organization, the person(s) executing this Agreement on behalf of the organization, hereby represent and warrant to the Company and each other Member that: (a) if such Member is an organization, that it is duly organized, validly existing, and in good standing under the law of its state of organization and that it has full organizational power to execute and agree to this Agreement and to perform its obligations hereunder; (b) the Member is acquiring its interest in the Company for the Member's own account as an investment and without an intent to distribute the interest; and (c) the Member acknowledges that the interests have not been registered or qualified under the Securities Act of 1933 or any state securities laws, and may not be resold or transferred by the Member without appropriate registration or qualification or the availability of an exemption from such requirements. 4.6 CONFLICTS OF INTEREST - A Member does not violate a duty or obligation to the Company merely because the Member's conduct furthers the Member's own interest. A Member may lend money to and transact other business with the Company. The rights and obligations of a Member who lends money to or transacts business with the Company are the same as those of a person who is not a Member, subject to other applicable law. No transaction with the Company shall be voidable solely because a Member has a direct or indirect interest in the transaction if either (i) the transaction is fair to the Company, or (ii) the disinterested Managers or disinterested Senior Members, in either case knowing the material facts of the transaction and the Member's interest, authorize, approve, or ratify the transaction. ARTICLE V MANAGERS 5.1 MANAGERS - Subject to Section 4.1 and the last sentence of Section 5.4, any decisions concerning the business affairs of the Company shall be made by the Managers, or their designees. The Company shall have three Managers, provided that following the Changeover Date the Company shall have five Managers, unless a different number is designated by a Supermajority of the Senior Members. The Managers shall hold office until removed by the affirmative vote of a Supermajority of the Senior Members or he/she resigns. A new Manager shall be elected by the affirmative vote of a Supermajority of the Senior Members. Notwithstanding the preceding, Acacia, so long as it retains a Percentage Interest of at least 10%, shall have the right to appoint one of the Managers up to and including the Changeover Date and three of the Managers following the Changeover Date, and to remove and replace such appointee (provided that until the Trigger Date Acacia's appointee shall be Paul R. Ryan, so long as he is able to serve). The initial Managers shall be Browne, Lloyd and Paul R. Ryan. The Managers (acting by a Majority) shall establish the policies and procedures for the management of the business and affairs of the Company, and shall be charged with oversight of the Company's operations and affairs. The Managers shall delegate to the Chief Executive Officer responsibility for the management and direction of 11 the day-to-day activities of the Company. At all times during which a duly appointed Chief Executive Officer is acting in such capacity for and on behalf of the Company, no individual Manager other than the Chief Executive Officer shall take any action for or on behalf of the Company except as expressly provided for in this Agreement.

The Chief Executive Officer shall have the power and authority, without the further consent or approval of the Managers, the Members or the Senior Members, and notwithstanding any other provision of this Agreement, to take any of the foregoing actions (or any other action) which is contemplated by, or does not materially vary from, the Budget to the extent the Budget contemplates that such action will be taken within one year from the date of this Agreement. 5.5 CONSULTATION WITH MEMBERS - Notwithstanding Section 5.4, the Chief Executive Officer and Managers must consult with the Senior Members prior to taking any of the following actions: (a) The approval of a budget for the ensuing financial period; (b) Any mortgage, lien, charge, pledge, creation of a security interest, or encumbrance on or in any Company Property with a fair market value in excess of $500,000; or (c) The creation, incurrence, assumption, guarantee or liability for, contingently or otherwise, by the Company or any of its Affiliates, of any indebtedness which in the aggregate exceeds $500,000. For purposes of this Section 5.5, the term "consult" does not require the approval or the consent of each of the Senior Members in order for the Managers to take the actions set forth in this Section 5.5. 5.6 COMPENSATION OF MANAGERS - Each Manager shall be reimbursed for all reasonable expenses incurred by such Manager in managing the Company and shall be entitled to compensation, if any, in an amount to be determined from time to time by a Majority of the Managers, subject to the terms of any agreement of employment or retention between the Company and such Manager. 5.7 MANAGERS' STANDARD OF CARE - A Manager's duty of care in the discharge of the Manager's duties to the Company and the Members is limited to refraining from engaging in grossly negligent or reckless conduct, intentional misconduct, or a knowing 13 violation of law. In discharging its duties, a Manager shall be fully protected in relying in good faith upon the records required to be maintained under Article IV and upon such information, opinions, reports or statements by any of its other Managers, Members, or agents, or by any other person, as to matters the Manager reasonably believes are within such other person's professional or expert competence and who has been selected with reasonable care by or on behalf of the Company, including information, opinions, reports or statements as to the value and amount of the assets, liabilities, profits or losses of the Company or any other facts pertinent to the existence and amount of assets from which distributions to Members might properly be paid. 5.8 INDEMNIFICATION - In the absence of fraud, material breach of fiduciary duty, willful violation of this Agreement, or other willful misconduct on the part of the Chief Executive Officer, the Chief Operating Officer or any Manager (which malfeasance shall have given rise to the matter at issue), the Company shall indemnify and hold such person harmless from and against any loss, expense, damage or injury suffered or sustained by any of them by reason of any acts, omissions, or alleged acts or omissions arising out of any activity performed or not performed by, for, on behalf of, or otherwise related to the interests of the Company. This indemnification shall include, but not be limited to, (i) the payment of reasonable attorneys' fees and other expenses incurred in settling any claim or threatened action (where such settlement is approved by counsel to the Company) or in connection with any legal proceeding, and (ii) the removal of any liens affecting the property of the Chief Executive Officer, the Chief Operating Officer or any Manager. ARTICLE VI CONTRIBUTIONS AND CAPITAL ACCOUNTS 6.1 INITIAL CONTRIBUTIONS - Each of the Original Members has heretofore made the Capital Contribution described for that Member on Schedule A. Acacia is making the Capital Contribution described for it at the time and on the terms specified on Schedule A. The value of the Capital Contributions shall be as set forth on Schedule A. No interest shall accrue on any Capital Contribution and no Member shall have the right to withdraw or be repaid any Capital Contribution except as provided in this Agreement. 6.2 ADDITIONAL CAPITAL CONTRIBUTIONS - No Member shall be required to make any additional Capital Contributions to the Company. Subject to Section 4.1, the Managers may at any time cause the Company to seek additional Capital Contributions to the Company by issuing additional Membership Interests. Such additional Membership Interests shall have such attributes and shall be issued at such price and upon such terms as shall be so approved; PROVIDED, HOWEVER, that the admission of any new Members shall be subject to the other provisions of this Agreement. Without limiting the foregoing, such price and terms may differ in any and all respects from the price and terms at which Membership Interests were issued or sold to the Members hereunder. The Managers shall do all things necessary to comply with the Act in connection with the issuance of such additional Membership Interests. Subject to the exceptions set forth below, each Member shall have the preemptive 14 right to purchase such additional Membership Interests up to its Percentage Interest, all for the same price and upon the same terms for such proposed issuance as shall be so approved. The Managers shall give written notice to each Member at least thirty (30) days prior to the issuance of any additional Membership Interests. Each such Member who intends to purchase a portion of the additional Membership Interests shall, within twenty (20) days of receipt of such written notice from the Managers, deliver written notice of such intention to the Managers. The failure of such a Member to give such notice of his or its intention to purchase additional Membership Interests shall be deemed to be (i) a waiver of such Member's right to purchase additional Membership Interests, (ii) a consent to the admission of any purchaser as a Member and (iii) a consent to the amendment to this Agreement to provide for such additional Membership Interests. The closing of the purchase of such additional Membership Interests shall be held at such time and place as the Managers shall determine. If the Company does not issue any of such additional Membership Interests within 180 days following the twenty (20) day period after receipt of the notice referred to above at a price and on terms no less favorable to the Company than the price and terms as shall have been so approved, the Company may not issue such additional Membership Interests without first complying with this Section 6.2, as if such additional Membership Interests were first being proposed for issuance. The foregoing provisions of this Section 6.2 shall be inapplicable to the issuance of interests in the Company in a Strategic Transaction and no Member shall have a pre-emptive right to participate in such a transaction. 6.3 NO INCREASE OF PERCENTAGE INTEREST - No loan or loans made by any Member to the Company shall increase any such Member's Percentage Interest. 6.4 MAINTENANCE OF CAPITAL ACCOUNTS - The Company shall establish and maintain Capital Accounts for each Member and Assignee. Each Member's Capital Account shall be increased by (1) the amount of any money actually contributed by the Member to the capital of the Company, (2) the fair market value of any Property contributed, as determined by the Company and the contributing Member at arm's length at the time of contribution (net of liabilities assumed by the Company or subject to which the Company takes such Property, within the meaning of Section 752 of the Code), and (3) the Member's share of Net Profits and of any separately allocated items of income or gain. Each Member's Capital Account shall be decreased by (1) the amount of any money actually distributed to the Member from the capital of the Company, (2) the fair market value of any Property distributed to the Member, as determined by the Company and the distributing Member at arm's length at the time of distribution (net of liabilities of the Company assumed by the Member or subject to which the Member takes such Property within the meaning of Section 752 of the Code), and (3) the Member's share of Net Losses and of any separately allocated items of deduction or loss. 6.5 REVALUATION OF COMPANY PROPERTY. (a) Upon the occurrence of a Revaluation Event, the Company shall revalue all Company Property (whether tangible or intangible) for Capital Account purposes to reflect their respective fair market values (as reasonably determined by 15 the Managers) immediately prior to the Revaluation Event, and the Capital Account of each Member shall be adjusted to account for that Member's allocable share (as determined under Article VII below) of the Net Profits or Net Losses that would have been realized by the Company had it sold all such property at their respective fair market values. (b) If the Company at any time distributes any of its assets in- kind to any Member, the Capital Account of each Member shall be adjusted to account for that Member's allocable share (as determined under Article VII below) of the Net Profits or Net Losses that would have been realized by the Company had it sold the assets that were distributed at their respective fair market values immediately prior to their distribution. 6.6 COMPLIANCE WITH SECTION 704(b) OF THE CODE - The provisions of this Article VI as they relate to the maintenance of Capital Accounts are intended, and shall be construed, and, if necessary, modified to cause the allocations of profits, losses, income, gain and credit pursuant to Article VII to have substantial economic effect under the Regulations promulgated under Section 704(b) of the Code, in light of the distributions made pursuant to Articles VII and VIII and the Capital Contributions made pursuant to this Article VI. Notwithstanding anything herein to the contrary, this Agreement shall not be construed as creating a deficit restoration obligation or otherwise personally obligate any Member to make a Capital Contribution in excess of the Initial Contribution. ARTICLE VII ALLOCATIONS AND DISTRIBUTIONS 7.1 ALLOCATIONS OF NET PROFITS AND NET LOSSES FROM OPERATIONS - After the allocation in Section 7.2, Net Profits and Net Losses for any final year or other period, shall be allocated among the Members in proportion to their Percentage Interests. 7.2 SPECIAL ALLOCATION. (a) QUALIFIED INCOME OFFSET. In the event any Member, in such capacity, unexpectedly receives an Offsettable Decrease, such Member will be allocated items of income and gain (consisting of a pro rata portion of each item of partnership income and gain for such year) in an amount and manner sufficient to offset such Offsettable Decrease as quickly as possible. (b) CORRECTIVE ALLOCATION. In the event any allocation of income or gain is made pursuant to Section 7.2(a), then items of income, gain, loss or deduction shall be specially allocated among the Members in such a manner so as to cause the Capital Account balances of the Members to equal the amounts the Capital Account balances would have been if the allocation under Section 7.2(a) had not occurred. 16 7.3 ALLOCATION FOR TAX PURPOSES - Except as otherwise provided herein, each item of income, gain, loss and deduction for federal and state income tax purposes shall be allocated among the Members in the same manner as its correlative item of income, gain, loss or deduction is allocated for Capital Account purposes pursuant to Sections 7.1 and 7.2 above; provided, however, that in the event that the book value of an item of Company property for Capital Account purposes differs from its adjusted basis for federal income tax purposes, the allocations of depreciation, amortization, cost recovery deductions, and gain or loss with respect to such property will be made for federal income tax purposes in a manner that takes into account the variation of such book value and adjusted tax basis in accordance with Section 704(c)(1)(A) of the Code and Treasury Regulations Section 1.704-1(b)(4)(i). The Company will select the "remedial method" for making any such allocations pursuant to Treasury Regulations Section 1.704-3(d). 7.4 TRANSFERS OF INTEREST - Upon the transfer of or other change in the Members' Percentage Interests during any fiscal year or other period, the Company shall allocate Net Profits or Net Loss or other items of income, gain, loss or deduction among the Members in a manner that takes into account their varying Percentage Interests pursuant to the "interim closing of the books method" pursuant to Code Section 706 and the Treasury Regulations thereunder. 7.5 INTERIM DISTRIBUTIONS - Subject to Section 7.6 and only to the extent cash is available for such purpose (as determined in the reasonable judgment of the Managers), the Company shall distribute to the Members in proportion to their Percentage Interests not less than 40% of the taxable income of the Company for such year. Such distributions shall be made in a timely fashion to allow the Members to satisfy their estimated, as well as annual, tax payment obligations relating to their allocable shares of such taxable income, but only to the extent cash is available for such purpose. Any other distributions may, in the Managers' sole and absolute discretion, be made to the Members in accordance with their Percentage Interests. 7.6 LIMITATIONS ON DISTRIBUTIONS - No distribution shall be declared and paid unless, after the distribution is made, the assets of the Company are in excess of all liabilities of the Company, except liabilities to Members in respect of their Capital Accounts. ARTICLE VIII TAXES 8.1 ELECTIONS - The Managers may make any tax elections for the Company allowed under the Code or the tax laws of any state or other jurisdiction having taxing jurisdiction over the Company. 8.2 TAXES OF TAXING JURISDICTIONS - To the extent that the law of any Taxing Jurisdiction so requires, each Member requested to do so by the Managers will submit an agreement indicating that the Member will make timely income tax payments to 17 the Taxing Jurisdiction and that the Member accepts personal jurisdiction of the Taxing Jurisdiction with regard to the collection of income taxes attributable to the Member's income, and interest, and penalties assessed on such income. If the Member fails to provide such agreement, the Company may withhold and pay over to such Taxing Jurisdiction the amount of tax, penalty and interest determined under the laws of the Taxing Jurisdiction with respect to such income. Any such payments with respect to the income of a Member shall be treated as a distribution for purposes of Article VII. The Company may, where permitted by the rules of any taxing Jurisdiction, file a composite, combined or aggregate tax return reflecting the income of the Company and pay the tax, interest and penalties of some or all of the Members on such income to the Taxing Jurisdiction, in which case the Company shall inform the Members of the amount of such tax interest and penalties so paid. 8.3 TAX MATTERS PARTNER - Browne shall act as tax matters partner of the Company pursuant to Section 6231(a)(7) of the Code. Browne shall take such actions as may be necessary to cause each other Member to become a notice partner within the meaning of Section 6223 of the Code. Any Member who is designated tax matters partner may not take any action contemplated by Code Sections 6222 through 6232 without the consent of Browne. 8.4 METHOD OF ACCOUNTING - The records of the Company shall be maintained in accordance with Generally Accepted Accounting Principles using such appropriate method of accounting as is selected by the Managers. ARTICLE IX TRANSFER OF MEMBERSHIP INTERESTS 9.1 ASSIGNMENT OF INTEREST - No Member shall (voluntarily, involuntarily or by operation of law), without the express written consent of each of the Senior Members which may be withheld in their sole discretion, give, sell, assign, transfer, mortgage, hypothecate, encumber, bequeath or devise its Membership Interest, and no Member or assignee of a Membership Interest shall permit any person or group of persons acting in concert to acquire beneficial ownership of 50% or more of the outstanding voting securities of such Member or assignee (any such disposition is hereinafter referred to as a "transfer"). Any purported transfer of all or any portion of a Membership Interest without such written consent shall be void and of no effect against the Company or the other Members. Notwithstanding the foregoing, a Member shall have the right, without compliance with the foregoing terms of this Section 9.1, to transfer all, but not less than all, of its Membership Interest to any Affiliate in which the Member is the owner of a one hundred percent (100%) equitable interest in such entity; provided, however, each of the Senior Members shall be entitled to transfer to any Affiliate its Membership Interest, but shall not be entitled to transfer any of its rights to participate in the management of the Company. 9.2 EFFECTIVE DATE OF TRANSFER - Every transfer of a Membership Interest shall be deemed to be effective, and the allocation of cash profits and losses pertaining to 18 such Membership Interest shall be allocated between the transferor and transferee, as of the close of business on the day in which such transfer shall have occurred. The profits, gains, losses, deductions and credits of the Company for the fiscal year during which such transfer occurs shall be allocated between or among the respective parties or the Members in a manner which is consistent with the interim closing of the books method under Section 706(c) and the Treasury Regulations thereunder, and the Capital Account of the transferor Member that is attributed to the transferred interest shall be determined and maintained in accordance with the provisions of Section 704(b) of the Code. 9.3 SUBSTITUTE MEMBER(S) - No assignee of a Membership Interest under Section 9.1, other than one who is already a Member, shall have the right to become a Member ("Substitute Member") in place of its transferor unless and until all of the following conditions are satisfied: (a) The transferor and Assignee have executed and delivered to the remaining Senior Members a written instrument of assignment, fully executed and acknowledged, setting forth the intention of the transferor and Assignee that the Assignee become a Substitute Member in the transferor's place; (b) The transferor and Assignee have executed and acknowledged such other instruments as the remaining Senior Members may deem necessary or advisable to effect the admission of such person as a Substituted Member in accordance with the provisions of applicable law, including without limitation, the written acceptance and adoption by such person of the provisions of this Agreement; and (c) A Majority of the Members, and each of the Senior Members, have consented in writing to the admission of such person as a Substitute Member, which consent may be withheld in each Member's or Senior Member's sole and absolute discretion. 9.4 NONSUBSTITUTED ASSIGNEES - Any Assignee who has not become a Substitute Member pursuant to this Article IX shall be deemed to take only the right of its assignor or transferor to share in profits, losses and distributions of the Company, but shall acquire no right to any legal interest in the Company nor the right to exercise any power granted to a Member under this Agreement. 9.5 ADMISSION OF ADDITIONAL MEMBERS - Additional Members or Senior Members shall not be admitted to the Company except with the written consent of a Supermajority of the Senior Members and, upon the admission of such Additional Members, the Membership Interests of all then-existing Members, both Senior and Regular, shall be diluted pro rata as a result of the admission of such Additional Members. 9.6 UPDATING OF SCHEDULE A - The Senior Members shall amend Schedule A hereto by means of a signed writing each time there is an addition or removal of a Member, a change in the Capital Contribution made by any Member or a change in the Percentage Interest of any Member. 19 9.7 PROCEDURES ON TRANSFERS OF MEMBERSHIP INTERESTS UPON OCCURRENCE OF TRIGGER EVENT (a) For purposes of this Section 9.7, the "Trigger Event" shall have occurred if, as of the Trigger Date, (i) the Company has not effected a Strategic Transaction or (ii) there is not in effect an agreement or letter of intent to effect a Strategic Transaction, provided that, if the transaction contemplated by such agreement or letter of intent is not consummated within six months after the original Trigger Date, then the Trigger Event shall be the earlier of the expiration of such six-month period or the termination of the transaction contemplated thereby, and the Trigger Date shall be the last day of such period. (b) For purposes of this Section 9.7, the "Trigger Date" shall be defined to mean the date on which the Fair Market Value of the Company is determined in accordance with Section 9.7(c)(iii). (c) (i) If the Trigger Event occurs, then Acacia (provided Acacia is then a Senior Member) shall have the right and option to purchase from the Original Members for cash such of the Membership Interests of the Original Members as is necessary to permit Acacia to be the holder of 51% of the Membership Interests. Such option shall be exercised by delivery of a written notice (the "Purchase Notice") to the Company and each of the Original Members within 30 days after the determination of the Fair Market Value pursuant to Section 9.7(c)(iii). (ii) Notwithstanding the preceding, if Acacia delivers the Purchase Notice, a Majority of the Original Members may, by delivery of written notice (the "Put Notice") to the Company and each other Member within 30 days following delivery of the Purchase Notice, require Acacia to purchase from the Original Members up to all of the Membership Interests then held by the Original Members for shares of Acacia voting common stock and/or cash in such proportion as the Original Members may, in their discretion, determine provided that the Original Members shall not have the right to require Acacia to pay cash in an amount greater than that payable pursuant to clause (i) above. If so requested by the Original Members, Acacia shall use its best efforts to effect such transaction as a reorganization within the meaning of Section 368(a) of the Code. (iii) The purchase price for a Membership Interest purchased pursuant to this Section 9.7 shall be equal to the product of (A) the Percentage Interest represented by such Membership Interest times (B) the Fair Market Value of the Company. For this purpose, "Fair Market Value" shall mean, a price agreed to between Acacia and a Majority of the Senior Members (other than Acacia), or if such agreement is not reached within 20 days following delivery of the notice referred to in the proviso to this sentence, the fair market value of the Company as determined by a nationally recognized independent investment banking or appraisal firm familiar with the industry in which the Company is engaged in business, provided that there shall be no obligation to determine the Fair Market Value unless Acacia gives written notice of its desire to have the Fair Market Value determined within 30 days after the date which is 18 months after the date of this 20 Agreement. Such firm shall be selected by mutual agreement of Acacia and a Majority of the Original Members, which selection shall be made within 15 days following delivery of the Purchase Notice. Such firm shall within 30 days following its selection deliver its written opinion (the "Fair Market Value Notice") of the fair market value of the Company, assuming a sale of the Company pursuant to an active marketing process. The Company and its Managers and officers shall cooperate with such firm to provide all requested information relating to the business and prospects of the Company. The fees and expenses of such firm shall be borne by Acacia. (d) Sales of Membership Interests under this Section 9.7 shall be made at the offices of the Company on a mutually satisfactory business day within 120 days after the Trigger Date. Delivery of any certificates or other instruments evidencing such Membership Interests, free and clear of all liens, claims, encumbrances and adverse interests of any kind (other than hereunder), and duly endorsed for transfer to Acacia shall be made on such date against payment of the purchase price therefor. The selling Members shall make all customary and usual representations and warranties to permit such transaction to be effected as a private placement or other transaction eligible for a regulatory exception to the registration requirements of applicable federal and state securities laws and/or as a tax-free reorganization. Unless the selling Members otherwise agree, all such sales shall be made by the selling Members pro rata in accordance with their respective Percentage Interests.
