(a) First, to the Members in proportion to the lesser of each Member’s (i) allocable share of the total Profit recognized from the disposition of such property and (ii) share of depreciation or amortization with respect to such property (as determined in the manner provided in Treasury Regulations Sections 1.1245-1(e)(2) and (3)), until each such Member has been allocated Recapture Gain equal to such lesser amount.

(b) Second, the balance of Recapture Gain shall be allocated among the Members whose allocable shares of total Profit from the disposition of such property exceed their shares of depreciation or amortization with respect to such property (as determined in the manner provided in Treasury Regulations Sections 1.1245-1(e)(2) and (3)), in proportion to their shares of total Profit (including Recapture Gain) from the disposition of such property; provided, however, that no Member shall be allocated Recapture Gain under this Section 7.2 in excess of the total Profit otherwise allocated to such Member from such disposition.

Except as otherwise provided below or unless otherwise required by the provisions of the Code or agreed by the Members, any Profit or Loss allocable to an interest in the Company which has been transferred during any year shall be allocated among the Persons who were holders of such interest during such year in proportion to the number of days during such year that each holder was recognized as the holder of the interest, without regard to the results of Company operations during the period the holder was recognized as the owner thereof.

7.4 Tax Credits. Unless otherwise required by the Code, any tax credits of the Company shall be allocated among the Members in accordance with their Participating Percentages.

The income allocated pursuant to this Section 7.5(a) in any taxable year shall consist first of gains recognized from the disposition of property subject to one or more nonrecourse liabilities of the Company, and any remainder shall consist of a pro rata portion of other items of income or gain of the Company. The allocation otherwise required by this Section 7.5(a) shall not apply to a Member to the extent provided in Treasury Regulation Section 1.704-2(f)(2) through (5).

(b) Qualified Income Offset. Notwithstanding any other provision of this Agreement, if a Member unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6) that causes or increases an Adjusted Capital Account Deficit with respect to such Member, items of Company gross income and gain shall be specially allocated to such Member in an amount and manner sufficient to eliminate such Adjusted Capital Account Deficit as quickly as possible.

(c) Gross Income Allocation. If at the end of any Company taxable year, a Member has an Adjusted Capital Account Deficit, such Member shall be specially allocated items of Company income or gain in an amount and manner sufficient to eliminate such deficit Adjusted Capital Account Deficit as quickly as possible.

Notwithstanding Section 10.2 or any other provision of this Agreement, all decisions relating to any contract or other arrangements between the Company and any Member or any Affiliate of any Member, including the License, shall be made solely by the Members that are not parties to such arrangement and whose Affiliates are not parties to such arrangement (the “Other Members”). Any such decision shall require the approval of all of the Other Members if such matter is a Major Decision or the approval of Members having a majority of the Participating Percentages of the Other Members if such matter is not a Major Decision. Such matters shall include any decision to exercise or waive any rights or remedies of the Company under, or to amend or modify, the License or any other contract or arrangement from time to time in effect between the Company and any Member or any Affiliate of any Member.

10.5 Liability of the Members. A Member and its respective Affiliates, agents and employees shall not be liable, responsible or accountable in damages or otherwise to the Company or any of the Members or their successors or assigns for any acts performed or omitted within the scope of his authority as a Member, or otherwise conferred on the Member and such Affiliates, agents and employees by this Agreement, including the execution and delivery of deeds in lieu of foreclosure, provided that such Member or such Affiliates, agents or employees shall action good faith and shall not be guilty of willful misconduct or gross negligence.

10.6 Devotion of Time by Members. Each Member and its agents, Affiliates, employees and agents of Affiliates shall devote such time to the Company business as is reasonably necessary to manage and supervise the Company business and affairs in an efficient manner and to accomplish the purposes of the Company. Each Member and each employee, agent or Affiliate thereof shall be free to engage in other business ventures whether or not directly competing with the Company, or to exploit business opportunities whether or not arising from the conduct of Company business.

10.7 Other Business of Members. Subject to Section 11.8, each Member and its Affiliates may engage in or possess any interests in other business ventures of any kind, independently or with others. Subject to Section 11.8, neither the Company, any Member, nor the holder of any interest in the Company shall have any right by virtue of this Agreement or the relationship created hereby in or to such ventures or activities or to the income or profits derived therefrom, and the pursuit of such ventures, even if competitive with the business of the Company, shall not be deemed wrongful or improper.

10.8 Tax Matters Partner. AJG, for so long as it shall be a Member, shall be the “tax matters partner” (within the meaning of Section 6231 of the Code) of the Company, and as such, subject to Section 10.2, shall have all powers and authorities granted tax matters partners under the applicable provisions of the Code and any regulations promulgated thereunder. All costs and expenses incurred by the tax matters partner in connection with an audit by the Internal Revenue Service or other government tax agency of a Company income tax return shall be borne by the Company.

10.9 Election to Adjust Basis. In the event of a distribution of property made in the manner provided in Section 734 of the Code (or any comparable provision of any succeeding law), or in the event of a transfer of any membership interest in the Company permitted by this Agreement made in the manner provided in Section 743 of the Code, the Members, in their sole discretior, may make or revoke on behalf of the Company the election referred to in Section 754 of the Code permitting adjustments to basis as provided in Sections 734 and 743 of the Code. Any additional costs or expenses incurred by the Company as a result of such an election shall be borne pro rata by the Member or Members benefiting from such an election.

10.10 Company Indemnification of Members. The Company shall indemnify, defend, and hold the Members and their respective Affiliates, officers, directors, employees and agents, on their respective successors, executors, administrators or personal representatives harmless from and against any loss, liability, damage, cost or expense (including reasonable attorneys’ fees) sustained or incurred as a result of any act or omission concerning the business or activities of the Company; provided that the Member or any Affiliate, employee, or agent is not guilty of gross negligence, willful misconduct or violation of fiduciary duty and was acting in good faith within what it reasonably believed to be the scope of its authority for a purpose which it reasonably believed to be not opposed to the best interests of the Company. The foregoing indemnity shall not be enforceable against any Member personally but solely from such Member’s interest in the Company.

11.1 Admission of Members. Each of NOX and AJG is hereby recognized and admitted as a Member of the Company. No other person shall be recognized or admitted as a Member of the Company unless such person has satisfied the requirements of Article 12.

11.2 Limited Liability. Except to the extent provided in Section 11.5, the debts, obligations and liabilities of the Company, whether arising in contract, tort, or otherwise, shall be solely the debts, obligations, and liabilities of the Company, and the Members shall not be obligated personally for any such debt, obligation or liability of the Company solely by reason of being a Member of the Company. Except as provided in Section 11.5, no Member, in its capacity as a Member of the Company, shall be responsible or liable for any indebtedness or obligation of any other Member, nor, except to the extent provided in Section 11.6, shall the Company be responsible or liable for any indebtedness or obligation of any Member.

11.3 No Individual Authority. Except as otherwise expressly provided in this Agreement or in the Act, no Member, acting alone, shall have any authority to act for, or to create, undertake or assume any liabilities, obligations or responsibilities on behalf of the Company or any other Member.

11.4 Representations by Members. Each Member represents and warrants to the other Members and to the Company that (i) all transactions contemplated by this Agreement to be performed by such Member have been duly authorized by all necessary action and do not require the consent or approval of any third party, (ii) such Member has all necessary power with respect thereto, (iii) the consummation of such transactions will not (and with the giving of notice or lapse of time or both would not) result in a breach or violation of, or a default or loss of contractual benefits under, any trust agreement or other agreement by which such Member or any of such Member’s properties is bound, or any statute, regulation, order or other law to which such Member or any of such Member’s properties is subject, or give rise to a lien or other encumbrance upon any of such Member’s properties or assets, and (iv) this Agreement is a valid and binding agreement on the part of such Member, enforceable in accordance with its terms.

11.5 Indemnification by the Members. Each Member hereby agrees to indemnify the Company and each of its other Members and hold them each harmless from and against all liability, loss, cost, damage and expense (including attorneys’ fees and costs incurred in the investigation, defense and settlement of the matter) which the Company or any of such other Members shall ever sustain, suffer or incur which relate or arise out of or in connection with a breach by the indemnifying Member of any representation, warranty or covenant made by the indemnifying Member in this Agreement, in any agreement or instrument delivered pursuant hereto, on any other agreement with the Company. If the Company is made a party to any litigation or otherwise incurs any loss or expense as a result of or in connection with any Member’s personal obligations or liabilities unrelated to Company business, such Member shall indemnify and reimburse the Company for all such loss and expense incurred, including reasonable attorneys’ fees. The liability of any Member pursuant to this Section 11.5 may be assessed against such Member’s interest in the Company, including the right to receive any distributions of Net Cash Receipts; provided, however, the liability of a Member under this Section 11.5 shall not be limited to such Member’s interest in the Company but shall also be enforceable against such Member personally.

11.6 Indemnification by the Company. The Company shall indemnify each of its Members and former Members for all costs, losses, liabilities and damages paid or incurred by any of them in connection with the business of the Company, including any judgments, settlements, penalties, fines and expenses incurred in a proceeding to which any such person is a party because the person is or was a Member of the Company, to the fullest extent provided or allowed by the Act or any other applicable laws; provided, however, that such liability does not arise by reason of the willful misconduct or gross negligence of such Member or any matter described in Section 11.5 with respect to which the Member is obligated to indemnify the Company.

11.7 Rights of a Former Member. Except as otherwise provided herein, no Member shall have the right or power to resign or withdraw by voluntary act from the Company. If a

Member shall cease to be a Member, and if the Company is not then dissolved, then (i) such former Member shall be in breach of this Agreement, and (ii) notwithstanding the terms of Section 18-604 of the Act, such former Member shall not thereby be entitled to receive the fair value of such former Member’s membership interest in the Company or any other payment or any other distribution except as specifically provided in this Agreement.

11.8 Covenants. Notwithstanding anything contrary herein, each Member covenants as follows:

(a) Confidential Information. Each Member acknowledges the economic value of the Confidential Information (as defined below) of the Company. Accordingly, during the Confidential Restricted Period (as defined below), each such Member shall not, in whole or in part, directly or indirectly:

(i) divulge, furnish, make available or disclose any Confidential Information in any manner to any person, firm, corporation, partnership, limited liability company, association or other entity, except with respect to business of the Company where a Confidentiality Agreement in substantially the form of Exhibit E attached hereto has been obtained for the benefit of the Company;

(ii) use any Confidential Information for itself or for any other Person except as may be necessary in connection with the performance of its duties hereunder; or

(iii) bring to the Company’s offices nor use, disclose to the Company, or induce the Company to use, any confidential information or documents belonging to a third party.

As used herein, the term “Confidential Information” shall mean all information used in or relating to the Intellectual Property or the business of the Company which is not generally known to the competitors of the Company, whether or not a trade secret as defined under applicable law, and which gives an advantage to the Company, including, without limitation, its patents, know-how and other intellectual property, its development plans, designs, specifications, flow charts, processes, formulas, data, all such information relating to the identity of the potential and actual customers of the Company, their respective methods of operation, financial data and pricing policies. Notwithstanding the foregoing, the term “Confidential Information” shall not include (i) any information which is or becomes publicly known through no wrongful act of a Member; (ii) any information which is rightfully received by a Member from any third party who is not known by the Member to be bound by any similar restriction; and (iii) any information required to be disclosed by order of a court of competent jurisdiction, administrative body or governmental body, or by subpoena, summons or legal process, or by law, rule or regulation, but only to the extent required by law and after the Member required to make such disclosure has provided to the Company prompt notice of such disclosure, if such notice is permitted by law.

As used herein, the term “Confidential Restricted Period” with respect to each Member shall mean with respect to each particular item of Confidential Information: (a) the period commencing with the date such Member first becomes a Member of the Company and ending three (3) years after such Member ceases to be a Member of the Company if the item of Confidential Information at issue does not constitute a trade secret; or (b) the period commencing with the date such Member first becomes a Member of the Company and continuing indefinitely, if the item of Confidential Information at issue constitutes a trade secret, until such item of Confidential Information at issue ceases to be a trade secret, but in no event ending earlier than three (3) years after such Member ceases to be a Member of the Company.

Each Member shall provide at least the same care to avoid disclosure or unauthorized use of the Confidential Information as it generally provides to protect its own proprietary information, which shall, in all events, equal or exceed a standard and level of care generally recognized as being reasonable for the protection of highly confidential information.

Notwithstanding anything herein to the contrary, each Member (and each employee, representative, or other agent of such Member) may (i) consult any tax advisor regarding the U.S. federal income tax treatment or tax structure of the transaction, and (ii) disclose to any and all persons, without limitation of any kind, the U.S. federal income tax treatment and tax structure of the transaction and all materials of any kind (including opinions or other tax analyses) that are provided to the Member relating to such tax treatment and tax structure. For this purpose, “tax structure” is limited to any facts relevant to the U.S. federal income tax treatment of the transaction and does not include information relating to the identity of the Members.

(b) Diversion of Customers. For so long as a Member is a Member and for a period of three (3) years thereafter (the “Restricted Period”), a Member shall not, either directly or indirectly, on its own account or as a partner, joint venturer, consultant, employee, agent, member or shareholder of any other Person or in any other capacity, in any way, solicit, divert or take away, or attempt to solicit, divert or take away, any potential transaction with the Company’s customers or potential customers, wherever located.

(c) Solicitation for Employment. Throughout the Restricted Period, a Member shall not, either directly or indirectly, on its own account or as a partner, joint venturer, consultant, employee, agent, member or shareholder of any other Person or in any other capacity, in any way, solicit or hire for employment or for engagement as an independent contractor in a business that is competitive with the business of the Company any person who is then, or within a period of twelve (12) months prior to any such relevant solicitation was, an employee of or independent contractor engaged by the Company.

(d) Business Opportunities. Throughout the period it is a Member of the Company, a Member shall not directly or indirectly have any financial interest in or derive any financial benefits from contacts made by the Company with any third party (except in its capacity as a Member of the Company) without first disclosing such interest or benefit to the other Members and obtaining the approval of all such other Members thereto.

(e) Inventions. All Inventions (as defined below) shall be the sole and exclusive property of the Company. Such ownership of Inventions shall inure to the benefit of the Company from the date of the conception, creation or fixation of the Invention in a tangible medium of expression, as applicable. All newly-created copyright aspects of the Inventions, whether created solely or jointly, shall be considered a “work-made-for-hire” within the meaning of the Copyright Act of 1976, as amended. If and to the extent the Inventions, or any part thereof, are found by a court of competent jurisdiction not to be a “work-made-for-hire” within the meaning of the Copyright Act of 1976, as amended, each Member agrees that all exclusive, right, title and interest in and to those newly-created copyrightable aspects of the Inventions, and all copies thereof, are hereby expressly assigned automatically to the Company without further consideration. Any agreement entered into by a Member and a third party in connection with the development of an Invention shall require the prior consent of the Company and shall further include substantially the same terms as those appearing in this Section 11.8(e) to ensure that the Company obtains the same rights in the Inventions generated under such third party agreement as those set forth in this Section 11.8(e). Each Member agrees to: (a) assist the Company in obtaining and enforcing all rights and other legal protections for the Inventions; (b) perform all acts deemed necessary or desirable by the Company to permit and assist it, at the Company’s expense, in registering, recording, obtaining, maintaining, defending, enforcing and assigning Inventions or works made for hire in the International Market; and (c) execute any and all documents that the Company may reasonably request from time to time in connection therewith, including any copyright assignment document(s), without further consideration. Each Member hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as such Member’s agents and attorneys-in-fact to act for and in such Member’s behalf and instead of such Member, to execute and file any documents and to do all other lawfully permitted acts to further the above purposes with the same legal force and effect as if executed by such Member. This designation and appointment constitutes an irrevocable power of attorney and is coupled with an interest. Each Member agrees to promptly disclose to the Company all Inventions, all original works of authorship and all work product relating thereto. This disclosure will include complete and accurate copies of all source code, object code or machine-readable copies, documentation, work notes, flowcharts, diagrams, test data, reports, samples and other tangible evidence or results (collectively, “Tangible Embodiments”) of such Inventions, works of authorship and work product. All Tangible Embodiments of any Invention, work of authorship or work product related thereto will be deemed to have been assigned to the Company as a result of the act of expressing any invention or work of authorship therein.

As used herein, the term “Inventions” shall mean any and all inventions, developments, discoveries, improvements, works of authorship, concepts or ideas or expressions thereof, whether or not subject to patent, copyright, trademark, trade secret protection or other intellectual property right protection, and whether or not reduced to practice, which both (i) relate to or result from any Intellectual Property or the actual or anticipated business, work, research or investigation of the Company, and (ii) are conceived or developed by a Member while such Member has an interest in the Company or within one (1) year following termination of such Member’s interest in the Company.

The Members agree that the Inventions contemplated by this Section are only those inventions related to the remediation of combusted carbonatious materials.

(f) Remedies. The covenants of Section 11.8 above, singly and collectively are sometimes referred to herein as “Covenants.” Each Member agrees that the Covenants are the minimum such restrictions necessary to protect the goodwill, Confidential Information and legitimate business interests of the Company and its successors and assigns, that the time periods and the territorial areas described above (in view of the scope of the business to be conducted by the Company), are reasonable and necessary for said protection, and that damages cannot adequately compensate the Company in a event of a Member’s violation of any Covenant. Accordingly, each Member agrees that if it shall violate or breach any Covenant, then the Company shall be entitled to obtain injunctive relief against such Member, without bond but upon due notice, in addition to such further relief as may be available at law or in equity. In the event of the entry of any such injunction, such Member’s sole remedy shall be the dissolution of such injunction, if such is warranted following a full hearing, and all claims for damages by reason of the wrongful issuance of any such injunction are hereby waived by such Member. The Company’s obtaining of any such injunction shall not be considered an election of remedies or a waiver of any right by the Company to assert any other remedy or remedies the Company may have against a Member at law or in equity. Each Covenant shall be construed as an agreement which is independent of the other provisions of this Agreement and severable and separate, and the existence of any claim or cause of action against the Company, of whatever nature, shall not constitute a defense to the Company’s enforcement of any Covenant. Any of the foregoing applicable restricted periods will be extended with respect to a Member for any equivalent period of time during which such Member violates the provisions of this Section 11.8. To the extent any Covenant may be deemed unenforceable by virtue of its scope in terms of geographical area, length of time or otherwise, but may be made enforceable by limitations thereon, each Member agrees that such Covenant shall be modified and enforced to the fullest extent permissible under the laws and public policies of the jurisdiction in which such enforcement is sought. The parties hereto hereby authorize any court of competent jurisdiction to modify or reduce the scope of any such Covenant to the extent necessary to make such Covenant enforceable.

12.1 General Prohibition. A Member may not sell, transfer, encumber, pledge or assign all or any part of its interest in the Company except (a) to a Permitted Transferee in accordance with Section 12.2, (b) in accordance with the procedure set forth in Section 12.3, (c) in accordance with the procedure set forth in Article 13, (d) pursuant to the procedures of Article 14, or (e) with the prior written consent of all of the other Members, which consent may be granted or withheld in each Member’s sole and absolute discretion. In order for an assignee to constitute a substituted or additional Member, the conditions set forth in Section 12.8 must be satisfied. In no event shall a Member consent to an assignment of any interest of a Member in the Company unless in the opinion of counsel satisfactory to the Company such assignment (i) will not result in a termination of the Company for federal income tax purposes (or the transferring Member and its transferee jointly and severally indemnify the Company and each other Member against any and all loss or cost arising from such termination), (ii) will not result in the Company failing to qualify for an exemption from the registration requirements of the federal or any applicable state securities laws, (iii) will not result in the imposition of fiduciary responsibility on the Company, any Member, or any Affiliate of any of the foregoing under the Employee Retirement Income and Security Act of 1974, as amended from time to time (“ERISA”), and (iv) will not result in the violation of any term or provision of any agreement to which the Company is a party or the acceleration of any indebtedness of the Company.

12.2 Permitted Transfers. A Member may assign all or any part of its interest in the Company without the consent of any other Member to a “Permitted Transferee.” For purposes of this Agreement, the term “Permitted Transferee” shall mean, with respect to any Member (i) a partnership in which such Member, Persons controlled by such Member or Persons controlling such Member on the date hereof are the sole or controlling general partner(s) and other partners are Persons controlled by such Member, Persons controlling such Member on the date hereof, or members of the immediate family of such Member or Persons controlling such Member on the date hereof, (ii) a corporation controlled by such Member or persons controlling such Member on the date hereof, and all of the issued and outstanding capital stock of all classes of such corporation is owned and controlled by such Member, Persons controlled by such Member, Persons controlling such Member on the date hereof, or by members of the immediate family of such Member or of Persons controlling such Member on the date hereof, (iii) a trust controlled by such Member or Persons controlling such Member on the date hereof and for the benefit of such Member, Persons controlling such Member on the date hereof, or members of the immediate family of such Member or of Persons controlling such Member on the date hereof, (iv) a limited liability company controlled by such Member or Persons controlling such Member on the date hereof and all of the membership interests of which are owned by such Member, Persons controlled by such Member, Persons controlling such Member on the date hereof, or members of the immediate family of such Member or Persons controlling such Member on the date hereof, or (v) another Member. For purposes of this Agreement, the immediate family of any Person shall mean the spouse and lineal descendants (either natural or by adoption) of such Person.

Notwithstanding anything in this Section 12.2 to the contrary, a Member may not assign all or part of its interest in the Company if such assignment would, in the opinion of counsel to the Company, (v) result in a termination of the Company for federal income tax purposes (or the transferring Member and its transferee jointly and severally indemnify the Company and each other Member against any and all loss or cost arising from such termination), (w) result in the Company not qualifying for an exemption from the registration requirements of the federal or any applicable state securities laws, (x) result in the imposition of fiduciary responsibility on the Company, any Member, or any Affiliate of any of the foregoing under ERISA, or (y) result in the violation of any term or provision of any agreement to which the Company is a party or the acceleration of any indebtedness of the Company.

Notwithstanding the right of a Member to transfer all or any portion of its interest to a Permitted Transferee, a Permitted Transferee shall not be admitted as an additional or substituted Member of the Company unless and until the provisions of Section 12.8 are satisfied. Until the provisions of Section 12.8 are satisfied with respect to a Permitted Transferee, such Permitted Transferee shall not be a Member but shall be an assignee having the rights described in Section 1 2.7.

(a) If a Member (the “Transferring Member”) shall desire to transfer all or any portion of its interest as a Member of the Company (the “Offered Membership Interest”) to any Person other than a Permitted Transferee or pursuant to a transaction that has been approved by all of the other Members pursuant to clause (e) of Section 12.1, pursuant to a bona fide written offer (a “Third-Party Offer”) for the purchase of such interest in exchange for a cash price payable entirely at closing, the Transferring Member shall deliver written notice (the “Offer Notice”) to each other Member (the “Offeree Members”) setting forth the Participating Percentage that the Transferring Member desires to transfer and a copy of the Third-Party Offer. The Offer Notice shall constitute an offer (the “Offer”) by the Transferring Member to the Offeree Members to purchase the Offered Membership Interest in exchange for the price and on the terms set forth in the Third-Party Offer. The Offeree Members shall have the right, for a period of thirty (30) days after the Offer Notice is delivered, to accept the Offer in proportion to their Participating Percentages or in such other proportion as they may agree upon. The Offeree Members shall accept the Offer, if at all, by delivering of written notice setting forth such acceptance to the Transferring Member within the 30-day period described above.

(b) If the Offeree Members, in the aggregate, accept the Offer with respect to the entire Offered Membership Interest, the purchase and sale of the Offered Membership Interest shall close not later than sixty (60) days following the expiration of the 30-day period described in Section 12.3(a). At the closing, the Transferring Member shall deliver to those Offeree Members accepting the Offer an assignment of the Offered Membership Interest, free and clear of all liens and encumbrances. At the closing, the Offeree Members purchasing the Offered Membership Interest shall pay to the

Transferring Member immediately available funds in the aggregate amount of the price set forth in the Third-Party Offer.

(c) If the Offeree Members, in the aggregate, fail to accept the Offer with respect to the entire Offered Membership Interest within the 30-day period described in Section 12.3(a), then the Transferring Member may transfer the Offered Membership Interest to the Person submitting the Third-Party Offer, at the price and on the terms set forth therein, without the consent of any other Member provided that (i) such transfer is completed within one hundred twenty (120) days following the expiration of the 30-day period described in Section 12.3(a); (ii) such transfer complies with the limitations set forth in clauses (v) through (y) of Section 12.2; and (iii) such transfer shall be subject to Article 13, if applicable. Any Person acquiring an interest in the Company pursuant to this Section 12.3(c) shall not be a Member but shall be an assignee having the rights described in Section 12.7, until the provisions of Section 12.8 are satisfied with respect to such Person.

12.4 Involuntary Transfers. In the event (i) of the death or adjudication of insanity or incompetency of an individual Member, or (ii) any Member shall be adjudged bankrupt, enter into proceedings for reorganization or into an assignment for the benefit of creditors, have a receiver appointed to administer the Member’s interest in the Company, be the subject of a voluntary or involuntary petition for bankruptcy, apply to any court for protection from its creditors, or have its interest in the Company seized by a judgment creditor (such Member being referred to herein as a “Bankrupt Member”), the personal representative or trustee (or successor-in-interest) of the deceased, insane or incompetent Member or Bankrupt Member shall be an assignee of such Member’s interest in the Company having the rights set forth in Section 12.7 and shall not become an additional or substituted Member unless and until the conditions set forth in Section 12.8 are satisfied; and any such Member’s estate (or successor-in-interest) shall be liable for all of its obligations as a Member.

12.5 Dissolution or Termination of Members. In the event of the dissolution of a Member that is a partnership, limited liability company or a corporation or the termination of a Member that is a trust, the successors-in-interest of the dissolved or terminated Member shall, for the purposes of winding up the affairs of the dissolved or terminated Member, have the rights of an assignee of such Member’s interest in the Company, as described in Section 12.7, and shall not become additional or substituted Members unless and until the conditions set forth in Section 12.8 are satisfied.

12.6 Transfers of Ownership Interests in Members. For purposes of this Article 12, any transfer or assignment of any direct or indirect ownership or other interest in a Member that (taking into account any prior such transfers or assignments, and any prior pledges, encumbrances or collateral assignments described below) results in such Member being controlled by a Person or Persons other than the Person or Persons that control such Member on the date hereof shall be deemed an assignment of the interest in the Company of such Member and therefore subject to all of the restrictions and provisions of this Article 12. In addition, any encumbrance, pledge or other collateral assignment of a direct or indirect ownership or other interest in a Member that, if the pledgee or other assignee were to exercise its right to acquire

such interest, would (taking into account any prior transfers or assignments described above and any prior such pledges, encumbrances or collateral assignments) result in such Member being controlled by a Person or Persons other than the Person or Persons that control such Member on the date hereof shall be deemed an assignment of the interest in the Company of such Member and therefore subject to all of the restrictions and provisions of this Article 12.

12.7 Status of Assignee. Any person who acquires all or any portion of the interest of a Member in the Company in any manner (including a Permitted Transferee), shall not be a Member of the Company unless and until the conditions of Section 12.8 are satisfied. Unless and until such conditions are satisfied, such person shall, to the extent of the interest acquired, be entitled only to the transferor Member’s rights, if any, in the Profits, Losses, Net Cash Receipts and other distributions to the Members pursuant to this Agreement, subject to the liabilities and obligations of transferor Member hereunder; but such person shall have no right to act on behalf of the Company or otherwise participate in the management of the business and affairs of the Company, and such person and his Participating Percentage shall be disregarded in determining whether the approval, consent or any other action has been given or taken by the Members. Any such assignee shall have the same right, subject to the same limitations, as the transferor Member had under the provisions of this Article 12 to assign its interest as a Member (including the right to assign such interest to any Permitted Transferee of such Member pursuant to Section 12.2), but any such further assignee shall have only the rights set forth in this Section 12.7 and shall not become an additional or substituted Member of the Company unless and until the conditions of Section 12.8 have been satisfied.

12.8 Admission Requirements. No assignee of all or any portion of a Member’s interest in the Company (including a Permitted Transferee) or any other person shall be admitted as an additional or substituted Member of the Company unless and until:

(a) such admission has been approved in writing by all of the other Members, which approval may be given or withheld in the sole discretion of each Member;

(b) such assignment is made in writing, signed by the assigning Member (or its successor) and accepted in writing by the assignee, and a duplicate original of such assignment has been delivered to each Member;

(c) the Company has received an opinion of counsel as contemplated by Section 12.1 or each Member has waived this requirement; and

(d) the assignee executes and delivers to the Company and each other Member a written agreement in form reasonably satisfactory to all of the other Members, pursuant to which such assignee agrees to be bound by and confirms the obligations, representations and warranties contained in this Agreement.

12.9 Effective Date of Assignment. If an assignment is made in accordance with this Agreement, unless otherwise required by the Code:

(a) the effective date of such assignment shall be the first date that both the written instrument of assignment is received by the other Members and, if required, approved by the other Members; provided that such assignee shall not be admitted as a Member unless and until the approvals and other requirements of Section 12.8 are satisfied;

(b) the Company and the other Members shall be entitled to treat the assignor of the assigned interest as the absolute owner thereof in all respects and shall incur no liability for allocations of Profits or Losses and distributions of Net Cash Receipts or other amounts made in good faith to such assignor until such time as the written instrument of assignment has been actually received by each Member, and recorded in the books of the Company, and, if required, approved by the Members described in Section 12.1; and

(c) any Profits and Losses shall be allocated between the assignor and the assignee of the assigned interest in the manner described in Section 7.3.

12.10 Status of Assignor. If there is a transfer or assignment of a Member’s interest in the Company, then, without regard to whether or when such assignee or transferee is admitted as a Member of the Company, from and after the effective date of such assignment or transfer, the assigning or transferring Member shall cease to be a Member with respect to the transferred or assigned interest; and if such Member has transferred or assigned his entire membership interest in the Company, upon the effective date of such transfer or assignment, such Member shall cease to be a Member of the Company.

12.11 Cost of Admission. The cost of processing and perfecting an admission contemplated by this Article 12 (including reasonable attorneys’ fees incurred by the Company) shall be borne by the party seeking admission as a Member to the Company.

If at any time Members owning seventy-five percent (75%) or more of the Participating Percentages (“Controlling Members”) shall desire to sell 50% or more of their aggregate membership interests in the Company to any third party (other than a Permitted Transferee), and the other Members do not elect to purchase such interests pursuant to Section 12.3, such Controlling Members shall give written notice thereof (a “Tag-Along Notice”) to each of the other Members (“Minority Members”) specifying the Participating Percentage to be sold and the price and terms of such sale. Each Minority Member may elect to participate in any such transaction as an additional selling Member on identical terms and conditions (with the aggregate price to be paid to the Controlling Members and the Minority Members electing to participate in the transaction allocated among them in proportion to the amounts each such Member would receive upon a hypothetical distribution of the aggregate purchase price pursuant to Section 15.4(c) in complete liquidation of the Company), by delivering a written notice thereof (a “Tag-Along Election Notice”) to the Controlling Members within fifteen (15) days after such

Minority Member’s receipt of such Tag-Along Notice, thereby electing to sell in such transaction any portion of its interest in the Company specified in the Tag-Along Election Notice which is less than or equal to the product of (i) the aggregate Participating Percentage which the Controlling Members propose to transfer in such transaction, multiplied by (ii) a fraction, the numerator of which is the Participating Percentage owned by such Minority Member, and the denominator of which is the aggregate Participating Percentage owned by the Controlling Members and all Minority Members electing to participate in such transaction. If Minority Members elect to sell interests pursuant to this Article 13, the aggregate Participating Percentage to be sold or transferred to such third party by the Controlling Members and the Minority Members shall remain constant.

14.1 Right to Initiate. Each Member shall have the right, exercisable at any time after two (2) years from the execution of this Agreement, in its sole discretion, to initiate the buy/sell procedures of this Article 14 in the manner described in Section 14.2.

14.2 Initiation and Elections. A Member (the “Initiating Party”) shall initiate the buy/sell procedures of this Article 14, if at all, by delivering to one or more Members (the “Other Party”) a written notice stating that the Initiating Party intends to proceed with this buy/sell procedure (a “Buy/Sell Notice”). The Buy/Sell Notice shall in addition set forth a gross value (without reduction for liabilities) for all of the assets owned by the Company other than cash and cash equivalents (such cash and cash equivalents being referred to herein as “Cash Assets” and such other assets being referred to herein as “Non-Cash Assets”), which assets shall include the Intellectual Property (the “Asset Value”), such value to be determined in the sole discretion of the Initiating Party. The Other Party shall have a period of ninety (90) days after the receipt of the Buy/Sell Notice (the “Exercise Period”) within which to notify the Initiating Party in writing (the “Reply Notice”) whether the Other Party shall either (x) sell to the Initiating Party its entire interest in the Company at a price computed in the manner set forth in Section 14.2(a) (the “Reply Price”), or (y) buy the entire interest in the Company of the Initiating Party at a price computed in the manner set forth in Section 14.2(b) (the “Buy/Sell Price”). If the Other Party timely gives the Reply Notice electing (x) above, the Initiating Party shall be conclusively deemed to have agreed to purchase, and the Other Party shall be conclusively deemed to have agreed to sell, the entire interest in the Company of the Other Party at the Reply Price. If the Other Party timely gives the Reply Notice electing (y) above, the Initiating Party shall be conclusively deemed to have agreed to sell, and the Other Party shall be conclusively deemed to have agreed to purchase, the entire interest in the Company of the Initiating Party at the Buy/Sell Price. If the Other Party fails to give a Reply Notice prior to the expiration of the Exercise Period, it shall be conclusively presumed that the Other Party has properly elected (x) above.

(a) Reply Price. The Reply Price for the purchase of the interest in the Company of the Other Party shall be the amount that would be distributed to the Other Party pursuant to Section 15.4(c) if the Company sold all of its Non-Cash Assets for cash in the amount of the Asset Value, sold all of its Cash Assets for cash in the amounts

shown for them on the books of the Company, applied such cash in full payment of all liabilities on the books of the Company, and the amount of such cash not so applied was available for distribution to the Members pursuant to Section 15.4(c) upon liquidation of the Company as of the date of the closing of this buy/sell.

(b) Buy/Sell Price. The Buy/Sell Price for the purchase of the interest in the Company of the Initiating Party shall be the amount that would be distributed to the Initiating Party pursuant to Section 15.4(c) if the Company sold all of its Non-Cash Assets for cash in the amount of the Asset Value, sold all of its Cash Assets for cash in the amounts shown for them on the books of the Company, applied such cash in full payment of all liabilities on the books of the Company, and the amount of such cash not so applied was available for distribution to the Members pursuant to Section 15.4(c) upon liquidation of the Company as of the date of the closing of this buy/sell.

(c) Price Determinations. The determination of the amount of the Buy/Sell Price, the Reply Price and any other amounts payable pursuant to this Article 14 shall be made by the independent accountants then employed by the Company on the basis of the Asset Value set forth in the Buy/Sell Notice and the Cash Assets and liabilities of the Company reflected on the books of the Company as of the date of closing of the buy/sell, and shall not include any adjustments for lack of liquidity or minority or majority ownership interests. Their determination shall be final and nonappealable, absent manifest error.

(d) Exclusivity of Buy/Sell Notice. Only one Buy/Sell Notice shall be entertained at any one time. The order of consideration of Buy/Sell Notices shall be determined by the date upon which the Other Party receives the Buy/Sell Notice in accordance with Article 17.

14.3 Closing. The transactions contemplated by the applicable buy/sell shall be consummated (herein, the “Closing”) at the principal office of the Company on the business day specified by the purchasing Member, provided that such date shall be not less than thirty (30) days and not more than sixty (60) days after the expiration of the Exercise Period. At the Closing, the purchase price shall be paid by the purchasing Member to the selling Member in cash, by wire transfer of immediately available funds to the account or accounts designated by the selling Member, or by certified bank check. The selling Member shall execute and deliver at the Closing an assignment, instrument of conveyance or other instrument appropriate to convey the entire interest in the Company of the selling Member to the purchasing Member, and shall deliver to the purchasing Member such evidence as the purchasing Member may reasonably request showing that the interest in the Company being sold is owned free and clear of any and all claims, liens and encumbrances of any kind or nature.

14.4 Payment of Loans. If there shall be any outstanding loans due from the Company to the selling Member or any Affiliates thereof (other than loans payable pursuant to Section 8.1(a), which shall be taken into account in determining the Reply Price or the Buy/Sell Price, as may apply), such loans, including accrued and unpaid interest, shall be purchased at par by the purchasing Member as a condition precedent to the Closing. The purchase price for such

loans shall be paid in full at the Closing in the same manner as the Reply Price or the Buy/Sell Price (as may apply) is paid. At the Closing, the selling Member (or any Affiliates thereof) shall deliver and endorse without recourse to the purchasing Member each note or other instrument evidencing such loans and all documents securing such loans (including any loans referred to in Section 8.1(a)).

14.5 Other Remedies for Noncompliance. It is the intent of the Members that the requirements or obligations, if any, of any Member to sell or purchase an interest in the Company in accordance with the provisions of this Article 14 shall be enforceable by an action for specific performance, with the same force and effect and at least to the same extent as is permitted at law or in equity for the specific performance of a contract relating to the purchase of real property or an interest therein.

14.6 Assignees. For purposes of this Article 14, the interest in the Company of each Member shall include all membership interests owned by such Member and any portion of such interest that is owned by any Affiliate of such Member or that such Member has assigned or transferred to an Affiliate of such Member or any other Person (other than to a Person that is a Member or Affiliate of any other Member at the time of such transfer). Any elections made by a Member under this Article 14 shall bind each Affiliate of such Member and any such assignee of such Member. All references in this Article 14 to a Member shall include all Affiliates of such Member and, except as provided above, all Persons to which such Member has transferred or assigned any portion of his membership interest in the Company.

14.7 Additional Effects of a Buy/Sell. If the selling Member or any Affiliate thereof is a guarantor or an indemnitor of or with respect to any obligations of the Company, a condition precedent to the Closing shall be that the purchasing Member shall obtain a release of such guaranty or liability; or, if such a release is not so obtainable and the selling Member agrees, the purchasing Member shall fully indemnify the selling Member and his Affiliates with respect to any such obligations. Any such indemnity by the purchasing Member shall be secured by its right to all distributions by the Company (including both distributions with respect to such purchased interest in the Company and with respect to all other interests in the Company of the purchasing Member or his Affiliates) arising from and after the date there has been a default on an indemnified debt or obligation of the Company.

14.8 Right to Assign. The purchasing Member may assign its rights obtained with respect to any participating interest under this Article 14 in whole or in part to a third party who, upon Closing, shall become a Member of the Company, without the consent of the selling Member but subject to the consent of all other Members, provided that (a) the purchasing Member delivers written notice to the selling Member of such assignment and of the identity of the assignee prior to the Closing; (b) such assignment, in the opinion of counsel to the Company, would not require registration of any interests in the Company under the Securities Act of 1933 or any applicable state securities or “Blue Sky” law, or result in any violation of any such laws; and (c) no such assignment shall relieve the purchasing Member of his obligations and liabilities under this Article 14.

15.1 Dissolution of the Company. The Company shall be dissolved upon the happening of any of the following:

(a) the agreement of the Members pursuant to Section 10.2 to dissolve and wind up the affairs of the Company;

(b) any event that makes it unlawful for the Company business to be continued; or

The death, retirement, resignation, bankruptcy, court declaration of incompetence, or dissolution of any one or more Members or the occurrence of any other event that terminates the continued membership of any one or more Members (except as provided in the immediately preceding sentence) shall not cause the dissolution of the Company.

15.2 Winding Up of Affairs. In the event of the dissolution and liquidation of the Company for any reason, the Members shall commence to wind up the affairs of the Company and shall convert all of the Company’s assets to cash or cash equivalents within such reasonable period of time as may be required to receive fair value therefor. All items of income, gain, loss, deduction and credit during the period of liquidation shall be allocated among the Members in the same manner as before the dissolution.

15.3 Accounting. In the case of the dissolution and termination of the Company, prior to any distributions to Members pursuant to Section 15.4(c), a proper accounting shall be made of the Capital Accounts of the Members and of each item of income, gain, loss, deduction and credit of the Company from the date of the last previous accounting to the date of dissolution. A copy of such accounting shall be provided to all Members.

15.4 Final Distribution of Company Property. Upon termination of the Company, the Members shall apply and distribute the remaining property of the Company, together with the proceeds of any sales of same, as follows:

(a) first, all of the Company’s debts and liabilities shall be paid and discharged, except any debts (i) described in Section 8.1, or (ii) that are nonrecourse to the extent that the Members elect not to pay such debts;

(b) second, to establish any reserve which the Members may deem reasonably necessary for any contingent or unforeseen liabilities or obligations of the Company. Such funds may be placed in escrow by the Members for the purposes of disbursing such funds in payment of any of the contingencies, liabilities, or obligations, and, at the

expiration of such period as the Members shall deem advisable, the balance then remaining shall be distributed pursuant to Section 15.4(c); and

15.5 Certificate of Cancellation. Upon completion of the liquidation of the Company and the distribution of all Company property, the Company shall terminate and the Members shall have the authority to execute and record one or more Certificates of Cancellation of the Company as well as any and all other documents required or considered advisable by the Members to effectuate and evidence the dissolution and termination of the Company.

15.6 No Restoration of Deficit Capital Accounts. Except as otherwise expressly provided herein, at no time shall a Member with a deficit balance in its Capital Account have any obligation to the Company or to another Member or to any other person to restore such deficit balance.

16.1 Amendment of Agreement. This Agreement may be amended only with the written concurrence of all of the Members.

16.2 Amendment of Certificate. If this Agreement shall be amended pursuant to this Article 16, the Members shall cause the Certificate to be amended, to the extent required by applicable law, to reflect such change.
