(c)    After giving effect to the special allocations set forth in Sections 3.2 and 3.3 hereof, Profits and Losses for any fiscal year shall be allocated among the Members and Interest Holders pro rata in accordance with their respective Percentage Interests.

All Losses in excess of the limitation set forth in this Section 3.1(b) shall be allocated among Members pro rata in accordance with their respective Percentage Interests. Any Losses allocated pursuant to the previous sentence of this Section 3.1(b) shall be reversed with an allocation of Profits of an equal amount prior to any allocations pursuant to Section 3.1(a).

3.2    Special Allocations. The following special allocations shall be made in the following order:

(a)    Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2(f), notwithstanding any other provision of this Section 3, if there is a net decrease in Company Minimum Gain during any fiscal year, each Member and Interest Holder shall be specially allocated items of Company income and gain for such fiscal year (and, if necessary, subsequent fiscal years) in an amount equal to such Member’s and Interest Holder’s share of the net decrease in Company Minimum Gain, determined in accordance with Regulations Section 1.704-2(g). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Member and Interest Holder pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations Sections 1.704-2(f)(6) and 1.704-2(j)(2). This Section 3.2(a) is intended to comply with the minimum gain chargeback requirement in Regulations Section 1.704-2(f) and shall be interpreted consistently therewith.

(b)    Member Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2(i)(4), notwithstanding any other provision of this Section 3, if there is a net decrease in Member Nonrecourse Debt Minimum Gain attributable to a Member Nonrecourse Debt during any fiscal year, each Member and Interest Holder who has a share of the Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse Debt, determined in

accordance with Regulations Section 1.704-2(i)(5), shall be specially allocated items of Company income and gain for such fiscal year (and, if necessary, subsequent fiscal years) in an amount equal to such Member’s and Interest Holder’s share of the net decrease in Member Nonrecourse Debt Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(4). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Member and Interest Holder pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section 3.2(b) is intended to comply with the minimum gain chargeback requirement in Regulations Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(c)    Qualified Income Offset. In the event any Member or Interest Holder unexpectedly receives any adjustments, allocations, or distributions described in Regulations Sections 1.704- 1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) or 1.704-1(b)(2)(ii)(d)(6), items of Company income and gain shall be specially allocated to each such Interest Holder in an amount and manner sufficient to eliminate, to the extent required by the Regulations, the Adjusted Capital Account Deficit of such Interest Holder as quickly as possible; provided that an allocation pursuant to this Section 3.2(c) shall be made only if and to the extent that such Interest Holder would have an Adjusted Capital Account Deficit after all other allocations provided for in this Section 3 have been tentatively made as if this Section 3.2(c) were not in the Agreement. This Section 3.2(c) is intended to comply with the qualified income offset requirement in Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(d)    Gross Income Allocation. In the event any Member or Interest Holder has an Adjusted Capital Account Deficit at the end of any fiscal year which is in excess of the sum of (i) the amount such Interest Holder is obligated to restore pursuant to any provision of this Agreement, and (ii) the amount such Interest Holder is deemed to be obligated to restore pursuant to the penultimate sentences of Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), each such Interest Holder shall be specially allocated items of Company income and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 3.2(d) shall be made only if and to the extent that such Interest Holder would have a deficit Capital Account in excess of such sum after all other allocations provided for in this Section 3 have been made as if Section 3.2(c) hereof and this Section 3.2(d) were not in the Agreement.

(e)    Nonrecourse Deductions. Nonrecourse Deductions for any fiscal year or other period shall be specially allocated among the Members and Interest Holders pro rata in accordance with their respective Percentage Interests.

(f)    Member Nonrecourse Deductions. Any Member Nonrecourse Deductions for any fiscal year or other period shall be specially allocated to the Member or Interest Holder who bears the economic risk of loss with respect to the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Regulations Section 1.704-2(i)(1).

(g)    Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Code Section 734(b) (including any such adjustments

pursuant to Regulations Section 1.734-2(b)(1)) is required, pursuant to Regulations Sections 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be specially allocated to the Members and Interest Holders in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Regulations.

3.3    Curative Allocations.

The allocations set forth in Sections 3.1(b) and 3.2 hereof (collectively, the “Regulatory Allocations”) are intended to comply with the requirements of the Regulations. It is the intent of the parties hereto that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory Allocations or with special allocations of other items of Company income, gain, loss, or deduction pursuant to this Section 3.3. Therefore, notwithstanding any other provision of Section 3 (other than the Regulatory Allocations), the Board shall make such offsetting special allocations of Company income, gain, loss, or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made, each Member’s or Interest Holder’s Capital Account balance is, to the extent possible, equal to the Capital Account such Person would have had if the Regulatory Allocations were not terms of this Agreement and all Company items were allocated pursuant to Section 3.1(a). In exercising its discretion under this Section 3.3, the Board shall take into account future Regulatory Allocations that, although not yet made, are likely to offset other Regulatory Allocations previously made.

3.4    Other Allocation Rules.

(a)    For purposes of determining the Profits, Losses, or any other items allocable to any period, Profits, Losses, and any such other items shall be determined on a daily, monthly’ or other basis, as determined by the Board using any permissible method under Code Section 706 and the Regulations thereunder.

(b)    Except as otherwise provided in this Agreement, all items of Company income, gain, loss, deduction, and any other allocations not otherwise provided for shall be divided among the Members and Interest Holders in the same proportions as they share Profits or Losses, as the case may be, for the year.

(c)    The Members are aware of the income tax consequences of the allocations made by this Section 3 and hereby agree to be bound by the provisions of this Section 3 in reporting their shares of Company income and loss for income tax purposes.

(d)    Solely for purposes of determining a Member’s or Interest Holder’s proportionate share of the “excess nonrecourse liabilities” of the Company within the meaning of Regulations Section 1.752-3(a)(3), if any, such excess nonrecourse liability shall be allocated to the Members or Interest Holders as follows:

(i)    First, such excess nonrecourse liabilities shall be allocated to the Members and Interest Holders up to the amount of built-in gain allocable to such Person on

Code Section 704(c) property (as defined in Regulations Section 1.704-3(a)(3)(i)) or property for which reverse Code Section 704(c) allocations are applicable (as described in Regulations Section 1.704-3(a)(6)(i)) where such property is subject to the nonrecourse liability, to the extent such gain exceeds the gain described in Regulations Section 1.752-3(a)(2).

(ii)    Second, the balance of such excess nonrecourse liabilities, if any, shall be allocated to the Members and Interest Holders in accordance with their Percentage Interests.

(e)    To the extent permitted by Regulations Sections 1.704-2(h) and 1.704-2(i)(6), the Board shall endeavor to treat distributions of Available Cash as having been made from the proceeds of a Nonrecourse Liability or a Member Nonrecourse Debt only to the extent that such distributions would cause or increase an Adjusted Capital Account Deficit for any Interest Holder.

3.5    Tax Allocations: Code Section 704(c).

In accordance with Code Section 704(c) and the Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the capital of the Company shall, solely for tax purposes, be determined and allocated among the Members and Interest Holders under the rules prescribed by Regulations Section 1.704-3(d)(2) so as to take account of any variation between the adjusted basis of such property to the Company for federal income tax purposes and its initial Gross Asset Value (computed in accordance with clause (a) of the definition of “Gross Asset Value”).

In the event the Gross Asset Value of any Company asset is adjusted pursuant to clause (b) of the definition of “Gross Asset Value”), subsequent allocations of income, gain, loss, and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and its Gross Asset Value in the same manner as under Code Section 704(c) and under the rules prescribed by Regulations Section 1.704-3(d)(2).

Any elections or other decisions relating to such allocations shall be made by the Board in any manner that reasonably reflects the purpose and intention of this Agreement. Allocations pursuant to this Section 3.5 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Person’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision of this Agreement.

4.1    Quarterly Distributions. Except as otherwise provided in Section 10 hereof, Available Cash, if any, shall be distributed quarterly in the following order and priority:

(h)    First, to the Members, in proportion to the total amount distributable to each such Member pursuant to this Section 4.1(a), until each such Member receives an amount equal to the excess, if any, of (i) the sum of (x) such Member’s Unreturned Partnership Additional Capital Contributions and (y) the cumulative additional Capital Contributions made by such Member pursuant to Section 2.2(a) hereof from the date hereof to the end of the quarter preceding the quarter during which such distribution is made, over (ii) the sum of all prior distributions to such Member pursuant to this Section 4.1(a) during that same period; and

(i)    The balance, if any, to the Members pro rata in accordance with their respective Percentage Interests.

4.2    Amounts Withheld. All amounts withheld during any fiscal year pursuant to the Code or any provision of any state or local tax law with respect to any payment, distribution or allocation to the Company, the Members or the Interest Holders shall be treated for all purposes under this Agreement as amounts distributed pursuant to this Section 4 to the Members and the Interest Holders with respect to which such amounts are withheld, and shall reduce amounts otherwise distributable to each such Member during such period, provided that, if the amounts required to be withheld with respect to each Member or Interest Holder during such period exceed the amounts otherwise distributable to such Member or Interest Holder during such period, such Member or Interest Holder shall contribute to the Company an amount equal to such excess upon demand by OCI. The Board is authorized to withhold from distributions, or with respect to allocations, to the Members and Interest Holders and to pay over to any federal, state, or local government any amounts required to be so withheld pursuant to the Code or any provisions of any other federal, state, or local law, and may allocate any such amounts among the Members and Interest Holders in any manner that is in accordance with applicable law.

5.1    General Authority of the Board of Managers. Except as otherwise provided in this Agreement (including, without limitation, in this Section 5), the property and business of the Company shall be managed by the Board, which has, to the extent permitted by applicable law, all requisite right, power and authority to, and may, without the consent of Members, exercise all such powers and do all such lawful acts and things as are not directed or required by this Agreement or the Act to be exercised or done or consented to by the Members, including but not limited to, the right, power and authority to cause the Company to:

5.5    Indemnification of Members, Managers and Officers.

(a)    To the fullest extent permitted by applicable law, each Manager and each Officer (and their respective heirs, executors and administrators) shall be indemnified by the Company (and any receiver, liquidator or trustee of, or successor to, the Company) from and against any and all liabilities, obligations, losses, damages, penalties, costs or expenses (including, without limitation, all costs and expenses of defense, appeal or settlement reasonably incurred by or imposed upon him) in connection with or arising out of any action, suit or proceeding in which he may be involved and which relates in any way to the Company or its business and assets, or to which he may be made a party by reason of his being or having been a Manager or Officer of the Company or, at its request, a partner or officer of any partnership, limited liability company or corporation of

which it is a partner, stockholder or creditor and for which he is not entitled to be indemnified (whether or not he continues to be a Manager or Officer at the time of imposing or incurring such expenses); provided, however, that no such indemnification shall be provided hereunder in respect of matters as to which a court of competent jurisdiction has entered a final and non-appealable judgment in such action, suit or proceeding that he is liable for breach of any duty expressly imposed by this Agreement; intentional misconduct; a knowing violation of law; or any transaction from which such Manager or Officer derived an improper personal benefit. With respect to any criminal action or proceeding, no such indemnification shall be provided hereunder if such Manager or Officer had reasonable cause to believe that his or her conduct was unlawful. In the event of a settlement of any such action, suit or proceeding, indemnification shall be provided hereunder only in connection with such matters covered by the settlement as to which the Company is advised by counsel that the person to be indemnified did not commit a breach of duty; intentional misconduct; a knowing violation of law; derive an improper personal benefit from a transaction; or have reasonable cause to believe that his or her conduct was unlawful. Notwithstanding the foregoing, no indemnification shall be provided hereunder in respect of any claim by the Company or any Member against a Manager or Officer other than a claim for costs and expenses of defense, appeal and settlement reasonably incurred by or imposed on him and otherwise indemnifiable hereunder. The foregoing right of indemnification shall not be exclusive of other rights to which he may be entitled.

(b)    Each Member Covered Person shall be indemnified and held harmless by the Company, to the fullest extent permitted under applicable law, from and against any and all liabilities, obligations, losses, damages, penalties, costs or expenses (including, without limitation, all costs and expenses of defense, appeal or settlement reasonably incurred by such Member Covered Person or imposed upon such Member Covered Person, whether or not the dispute or proceeding involves the Company or any Manager, Officer or Member), reasonably incurred or suffered by any such Member Covered Person in connection with the activities of the Company, provided, that any such Member Covered Person shall not be so indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which such Member Covered Person is seeking indemnification or seeking to be held harmless hereunder, and taking into account the acknowledgments and agreements set forth in this Agreement, such Member Covered Person engaged in a bad faith violation of the implied contractual covenant of good faith and fair dealing or a bad faith violation of this Agreement. A Member Covered Person shall not be denied indemnification in whole or in part under this Section 5.5(b) because such Member Covered Person had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

(c)    The Company shall pay expenses as they are incurred by any Member Covered Person, Manager or Officer in connection with any action, claim, or proceeding that the Member Covered Person, Manager or Officer asserts in good faith to be subject to the indemnification obligations set forth in this Agreement, upon receipt of an undertaking from such Member Covered Person, Manager or Officer to repay all amounts so paid by the Company to the extent that it is finally determined that the Member Covered Person, Manager or Officer is not entitled to be indemnified therefor under the terms hereof.

(d)    If a claim for indemnification or payment of expenses hereunder is not paid in full within ten days after a written claim therefor has been received by the Company, the claimant may file suit to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim. In any such action the Company shall have the burden of proving that the claimant was not entitled to the requested indemnification or payment of expenses under applicable law.

(iv)    Public relations and advertising services;

9.2    Permitted Transfers. Subject to the conditions and restrictions set forth in Section 9.3 hereof, any Member or Interest Holder may at any time Transfer all or any portion of its Interests to (a) any Affiliate of the transferor described in clause (a) of the definition of the definition of “Affiliate”, (b) any Purchaser in accordance with Section 9.4 hereof (any such Transfer being referred to in this Agreement as a “Permitted Transfer”) or (c) the lenders (or the administrative agent or collateral agent therefor) under the OCI Credit Facility in connection with the pledge of Interests thereunder (or the exercise or remedies with respect thereto).

9.3    Conditions to Permitted Transfers. A Transfer shall not be treated as a Permitted Transfer under Section 9.2 hereof unless and until the following conditions are satisfied:

(e)    Except in the case of a Transfer of Interests involuntarily by operation of law, the transferor and transferee shall execute and deliver to the Company such documents and instruments of conveyance as may be necessary or appropriate in the opinion of counsel to the Company to effect such Transfer and to confirm the agreement of the transferee to be bound by the provisions of this Section 9. In the case of a Transfer of Interests involuntarily by operation of law, the Transfer shall be confirmed by presentation to the Company of legal evidence of such Transfer, in form and substance satisfactory to counsel to the Company.

(f)    Except in the case of a Transfer involuntarily by operation of law, the transferor shall furnish to the Company an opinion of counsel, which counsel and opinion shall be satisfactory to the Company, that the Transfer will not cause the Company to terminate for federal income tax purposes.

(g)    The transferor and transferee shall furnish the Company with the transferee’s taxpayer identification number, sufficient information to determine the transferee’s initial tax basis in the Interests transferred, and any other information reasonably necessary to permit the Company to file all required federal and state tax returns and other legally required information statements or returns. Without limiting the generality of the foregoing, the Company shall not be required to make any distribution otherwise provided for in this Agreement with respect to any transferred Interests until it has received such information.

9.4    Right of First Refusal. In addition to the other limitations and restrictions set forth in this Section 9, except as permitted by Section 9.2(a) hereof, no Member or Interest Holder shall Transfer all or any portion of its Interests (the “Offered Interest”) unless such Member or Interest Holder first offers to sell the Offered Interest pursuant to the terms of this Section 9.4, provided that, notwithstanding anything to the contrary herein, no Transfer arising out of the pledge of any Interest (including the exercise of remedies with respect to such pledge) by OCI pursuant to the OCI Credit Facility shall be subject to this Section 9.4.

(d)    In General. Should any Member or Interest Holder (the “Seller”) propose to transfer any of its Interest in the Company, such Seller shall first obtain a bona fide written offer (the “Purchase Offer”) for the purchase thereof from a responsible purchaser (the “Purchaser”) who is ready, willing and able to purchase the same, which offer shall provide for a purchase price payable in cash of the lawful money of the United States of America or other “hard” currency. The Seller shall give the other Members (the “Offerees”) written notice by registered or certified mail, the notice to be accompanied by a photostatic copy of such Purchase Offer. Such notice shall specify the Offered Interest, the name of the proposed purchaser, and the price for which such Offered Interest is proposed to be transferred. In the event such notice is given, then the Offerees shall have 30 days within which to elect to purchase the Offered Interest at the price and on the terms specified in said offer, provided that payment may be made in cash of the lawful money of the United States of America or other “hard” currency provided that the value of such payment equals the price specified in the Purchase Offer. Each Offeree shall have the option to purchase that portion of the Offered Interest as corresponds to a fraction, the numerator of which is such Offeree’s Percentage Interest, and the denominator of which is the aggregate Percentage Interests held by Offerees. In the event either Offeree shall not elect to purchase its entire pro rata share,

such share not purchased may be purchased by the other Offeree. An election shall be made by giving written notice to the Seller within said 30-day period by registered or certified mail stating the portion of the Offered Interest that such Offeree is willing to purchase. The Offerees electing to purchase the Offered Interest shall have 15 days after giving notice of such election to consummate such purchase. If the Seller shall give notice to the Offerees as herein required, and the Offerees shall not elect to purchase the entire Offered Interest within such 30-day period or shall fail to consummate such purchase within 15 days after such election, the Offered Interest may thereafter be transferred to said Purchaser.

(e)    Pledges. In the event that any Member or Interest Holder (the “Pledgor”) shall desire to pledge or otherwise encumber any of its Interest in the Company as security for the payment of a debt, such Pledgor shall give written notice of the pledging or hypothecation of such Interest to the other Members by giving written notice thereof by registered or certified mail to the other Members within 10 days after the making of the agreement pledging or hypothecating said Interest. Any such pledge or hypothecation agreement shall require the pledgee or party secured to assume and be bound by all of the obligations, terms and conditions of this Agreement. No such pledge or hypothecation agreement shall be made unless it shall provide that any sale of the Interest so pledged or hypothecated pursuant to the provisions of said pledge or hypothecation agreement shall be at public sale and after thirty (30) days’ notice shall have been given to the other Members by registered or certified mail of such sale. In the event any Pledgor shall have pledged or hypothecated any of its Interest in the Company and is unable or unwilling to redeem the same as provided for in the pledge or hypothecation agreement, such Pledgor agrees to notify the Members of its inability or unwillingness to redeem at least ten (10) days before the maturity of the pledge or hypothecation agreement and hereby, agrees to give to the Members the right to redeem the pledged Interest in the same proportions as such Members could have elected to purchase the pledged Interest pursuant to Section 9.4(a) hereof had it been an Offered Interest. In the event the Members shall redeem the Interest so pledged or hypothecated, the Pledgor who originally pledged or hypothecated said Interest shall, without further consideration, promptly execute and deliver to the Members all documents required to transfer to them the ownership of the Interest so pledged or hypothecated.

9.5    Involuntary Transfers. In the event that any Member or Interest Holder shall become a party to any proceeding or be subject to any legal process, the purpose of which is to require the involuntary transfer of any portion of the Interest in the Company of such Member, such Member shall immediately give notice by wire to the other of such Members of the existence or pendency of such legal proceeding or legal process.

9.6    Admission of Transferees as Members. Subject to the other provisions of this Section 9, a transferee of an Interest in the Company may be admitted to the Company as a substituted Member only upon satisfaction of the conditions set forth below in this Section 9.6:

(e)    The Interests with respect to which the transferee is being admitted were acquired by means of a Permitted Transfer or in the circumstances described in Section 9.2(c);

(f)    The transferee becomes a party to this Agreement as a Member and executes such documents and instruments as the Board may reasonably request (including, without limitation, amendments to the Certificate) and as may be necessary or appropriate to confirm such transferee as a Member in the Company and such transferee’s agreement to be bound by the terms and conditions hereof;

(g)    If the transferee is a Person other than an individual, the transferee provides the Company with evidence satisfactory to counsel for the Company that such transferee has made each of the representations and undertaken each of the warranties described in Section 6 hereof; and

(h)    A transferee of an Interest from a Member hereunder shall be admitted as a Member with respect to such Interest if, but only if, all of the other Members consent to such admission.

9.7    Rights of Unadmitted Assignees. A person who acquires one or more Interests but who is not admitted as a substituted Member pursuant to Section 9.6 hereof shall be entitled only to allocations and distributions with respect to such Interests in accordance with this Agreement, but shall have no right to any information or accounting of the affairs of the Company, shall not be entitled to inspect the books or records of the Company, and shall not have any of the rights of a Member under the Act or this Agreement.

In lieu of closing the transfer books as aforesaid, the Board may fix in advance a date, not exceeding 50 days preceding the date of any meeting of Members, or the date for making any distribution, or the date for the allotment of rights, or a date in connection with obtaining such consent, as a record date for the determination of the Members entitled to notice of, and to vote at, any such meeting, and any adjournment thereof, or entitled to receive any such distribution, or to any such allotment of rights, or to give such consent, and in such case such Members and only such Members as shall be Members of record on the date so fixed shall be entitled to such notice of, and to vote at, such meeting and any adjournment thereof, or to receive such distribution, or to receive such allotment of rights, or to exercise such rights, or to give such consent, as the case may be, notwithstanding any transfer of any Interest in the Company on the books of the Company after any such record date fixed as aforesaid.

(b)    Holders of Record. The Company shall be entitled to treat the holder of record of any Interest in the Company as the holder in fact thereof and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such Interest in the Company on the part of any other Person, whether or not it shall have express or other notice thereof, except as otherwise provided by the Act.

10.1    Liquidating Events. The Company shall dissolve and commence winding up and liquidating upon the first to occur of any of the following (“Liquidating Events”):

(f)    The finding by the Board or the issuance of a judicial determination under Section 18-802 of the Act that any event has occurred that makes it unlawful, impossible or impractical to carry on the business of the Company; or

(g)    At any time when there are no Members.

The Members hereby agree that, notwithstanding any provision of the Act, the Company shall not dissolve prior to the occurrence of a Liquidating Event. Upon the occurrence of any event set forth in Section 10.1(c), the Company shall not be dissolved or required to be wound up if the requirements of Section 18-801 of the Act for the avoidance of dissolution are satisfied (a “Continuation Election”). If it is determined by a court of competent jurisdiction that the Company has dissolved prior to the occurrence of a Liquidating Event, or if upon the occurrence of an event specified in Section 10.1(c) hereof, no Continuation Election is made, then within an additional 90 days, two-thirds (2/3) in number of the Members may elect to reconstitute the Company and continue its business on the same terms and conditions set forth in this Agreement by forming a new limited liability company on terms identical to those set forth in this Agreement. Upon any such election by two-thirds (2/3) in number of the Members, all Members shall be bound thereby and shall be deemed to have consented thereto. Unless such an election is made within 180 days after the event causing dissolution, the Company shall wind up its affairs in accordance with Section 10.2 hereof. If such an election is made within 180 days after the event causing dissolution, then:

(a)    The reconstituted limited liability company shall continue until the occurrence of a Liquidating Event as provided in this Section 10.1; and

(b)    All necessary steps shall be taken to cancel this Agreement and the Conversion Certificate and to enter into a new limited liability company agreement and certificate of formation; provided that the right of two-thirds (2/3) in number of the Members to reconstitute and continue the business of the Company shall not exist and may not be exercised unless the Company has received an opinion of counsel that the exercise of the right would not result in the loss of limited liability of any Member and neither the Company nor the reconstituted Company would cease to be treated as a partnership for federal income tax purposes upon the exercise of such right to continue.

10.2    Winding Up. Upon the occurrence of a Liquidating Event, the Company shall continue solely for the purposes of winding up its affairs in an orderly manner, liquidating its assets, and satisfying the claims of its creditors and Members and no Member shall take any action that is inconsistent with, or not necessary to or appropriate for, the winding up of the Company’s

business and affairs, provided that, all covenants contained in this Agreement and obligations provided for in this Agreement shall continue to be fully binding upon the Members until such time as the Company Property has been distributed pursuant to this Section 10.2 and the Certificate has been cancelled pursuant to the Act. The Board, or if the Board shall not exist or it shall not be possible for the Board to establish a quorum, such other liquidating trustee(s) as are appointed in accordance with the Act shall be the Liquidator. The Liquidator shall be responsible for overseeing the winding up and dissolution of the Company and shall take full account of the Company’s liabilities and Property and, to the extent determined by the Liquidator, the Property shall be liquidated as promptly as is consistent with obtaining the fair value thereof, and the proceeds therefrom together with any remaining Property, to the extent sufficient therefor, shall be applied and distributed in the following order:

(a)    First, to the payment and discharge of all of the Company’s debts and liabilities to creditors other than the Members;

(b)    Second, to the payment and discharge of all of the Company’s debts and liabilities to the Members; and

(c)    The balance, if any, to the Members and Interest Holders in accordance with their Capital Accounts, after giving effect to all contributions, distributions, and allocations for all periods.

(d)    The Members understand and agree that by accepting the provisions of this Section 10.2 setting forth the priority of the distribution of the assets of the Company to be made upon its liquidation, the Members expressly waive any right which they, as creditors of the Company, might otherwise have under the Act to receive a distribution of assets pari passu with other creditors of the Company in connection with a distribution of assets of the Company in satisfaction of liabilities of the Company, and hereby subordinate to said creditors any such right.

10.3    Notice of Dissolution. In the event a Liquidating Event occurs or an event occurs that would, but for provisions of Section 10.1, result in a dissolution of the Company, the Board shall, within 30 days thereafter, provide written notice thereof to each of the Members and to all other parties with whom the Company regularly conducts business (as determined in the discretion of the Board) and shall publish notice thereof in a newspaper of general circulation in each place in which the Company regularly conducts business (as determined in the discretion of the Board).

(e)    Whenever under the provisions of this Agreement or the Act notice is required to be given to any person, it shall not be construed to mean personal notice, but such notice may be given (i) in writing, by registered mail, addressed to such person at such address as appears on the books of the Company, and such notice shall be deemed to be given at the time when

the same shall be thus mailed, (ii) by electronic mail for notices in the ordinary course of business (e.g., notices of meetings of Managers) (with confirmation of the transmission), to such person at such electronic mail address as appears on the books of the Company, and such notice shall be deemed given when sent, if sent during normal business hours of the recipient, and on the next business day if sent after normal business hours of the recipient, and (iii) by facsimile (with confirmation of the transmission) to such person at such facsimile number as appears on the books of the Company, and such notice shall be deemed given when sent, if sent during normal business hours of the recipient, and on the next business day if sent after normal business hours of the recipient.

(f)    Whenever any notice is required to be given under the provisions of this Agreement or the Act, a waiver thereof in writing signed by the person or persons entitled to said notice, whether before or after the time stated therein, shall be deemed equivalent thereto.

11.4    Governing Law. The laws of the State of Delaware (without regard to the choice of law principles thereof) shall govern the validity of this Agreement, the construction of its terms, and the interpretation of the rights and duties of the Members.

11.5    Waiver of Action for Partition; No Bill For Membership Accounting. Each of the Members irrevocably waives any right that it may have to maintain any action for partition with respect to any of the Company Property. To the fullest extent permitted by law, each of the Members covenants that it will not (except with the consent of the Board) file a bill for Company accounting.

11.6    Implementation. Each of the Members agrees to promptly execute all instruments and to promptly do all other things necessary for the effectuation and implementation of this Agreement.

11.7    Counterparts. Any number of counterparts of this Agreement may be executed. Each counterpart will be deemed to be an original instrument and all counterparts taken together will constitute one agreement. The exchange of copies of this Agreement and of signature pages by facsimile constitutes effective execution and delivery of this Agreement as to the parties and may be used in lieu of the original Agreement. Signatures of the parties transmitted by facsimile will be deemed to be their original signatures for any purpose whatsoever.

11.8    Execution; Effective Date. Each of the parties hereto agrees as follows:
