SECTION 4.1 Members' Capital Contributions. Each organizing member shall be required to make the capital contributions of cash to the Company at the times and in the amounts set forth across from such member's name as shown on Schedule A hereto, as the same may be amended from time to time pursuant to section 7 of this Article, by paying, or causing to be paid, said amount to the Company. Upon receipt of such payment, such amount shall be credited to the member's Capital Account (as such term is defined in Article VI) and shall be available to the Company to pay for the expenses associated with the Company's business activities, pursuant to the Company's procedures for approving expenditures. Members shall not be entitled to interest on the capital contributions. A member's failure to make a scheduled capital contribution shall result in a suspension of such member's voting rights until such time as the member makes the required contribution. The Board may establish an interest penalty for late payments, which interest penalty shall not exceed the lawful rate. For purposes hereof, a member's payment shall not be considered late until ten (10) business days after receipt of a notice from the Company of such member's failure to make a scheduled payment.

SECTION 4.2 Capital Accounts. Each member shall have a Capital Account that shall be credited with (i) the capital contributions (net of liabilities that the Company is considered to assume or take subject to Code section 752) contributed by such member to the Company; and (ii) allocations of Profits to it pursuant to Article VI, Section 2. Each member's Capital Account shall be debited with (a) the amount of cash and the Carrying Value (as defined in Article VI hereof) of other property distributed to such member (net of liabilities that such member is considered to assume or take under Section 752 of the Code) and (b) allocations of Losses to it pursuant to Article VI, Section 3. The provisions of this Agreement relating to the maintenance of Capital Accounts and procedures under liquidation of the Company are intended to comply generally with Regulations Section 1.704-1(b), and shall be interpreted and applied in a manner consistent therewith and, to the extent the subject matter thereof is otherwise not addressed by this Agreement, the provisions of such Regulations are hereby incorporated by reference.

Notwithstanding any requirements of law, the members agree, for purposes of maintaining their Capital Accounts, to be bound by the allocations contained in Article VI, notwithstanding any allocations for income tax purposes.

SECTION 4.3 Pre-formation Expenses. Each of the members shall be required to pay its own expenses incurred in connection with formation of the Company (collectively the "Pre-formation Expenses").

SECTION 5. Transfer or Sale of Interest. A member may not transfer, by sale, gift, assignment or any other means, some or all of its Interest in the Company to any party except with the two-thirds approval of the existing members; except that a member may sell, transfer, or assign some or all of its Interest without the prior approval of other members: (i) to an affiliate of the member; and (ii) to another member. However, in the case of any such sale, transfer, or assignment the transferring member shall not be released from its obligations hereunder unless the transferee agrees in writing to assume all obligations under this agreement with respect to the transferred interest in form and substance acceptable to the Board.

Schedule A hereto shall be amended to reflect a transfer of Interest(s) permitted under this Agreement. A transferee hereunder shall succeed to the Interest, voting and other rights of transferring member. In recognition that each member has only one vote in the management of the Company, in the case of transfer of less than the entire Interest of a member, the transferring member and the transferee shall mutually agree and notify the Company as to which of them shall exercise such vote and the Company shall not be liable for relying on such notice.

SECTION 6. Proof of Membership. This Agreement shall be proof of membership in the Company.

SECTION 7. Additional Capital Contributions.

Upon a member's withdrawal, such member's Interest shall be allocated to the remaining members pro rata based on the percentage Interest of each remaining member and the Board shall amend Schedule A to reflect such allocation. A withdrawing member may retain Carbon Reductions (as defined in Article V) associated with the withdrawing member's Interest that accrue to the member prior to the member's withdrawal and that the Board ratifies pursuant to Article V prior to or after the member's withdrawal. Carbon Reductions associated with the withdrawing member's Interest which accrue after the member's withdrawal and are ratified by the Board shall be allocated to the remaining members pro rata based on each remaining member's percentage Interest.

SECTION 9. Termination of Membership. The Company, by a two-thirds majority vote of the Board, may revoke a member's Interest in the Company if: (i) within thirty (30) days after receipt of notice thereof from the Company, a member fails to make a capital contribution to the Company as provided on Schedule A hereto; or (ii) a member becomes the subject of a voluntary or involuntary petition for bankruptcy that is not withdrawn within one hundred twenty (120) days of filing.

A revoked member's Interest shall be allocated to the remaining members pro rata based on each remaining member's percentage Interest and the Board shall amend Schedule A to reflect such allocation.

P. "Regulations" means the regulations, temporary and final, of the Treasury Department promulgated under the Code.

SECTION 2. Net Profits. Net profits for any taxable year of the Company shall be allocated to the members in proportion to their respective Interests.

SECTION 4. Distributions. Except upon dissolution and liquidation as set forth in Article XI, at such times as the Board shall determine, but no less than annually, the distributable cash of the Company, if any, shall be distributed to the members in proportion to their respective Interests.

Page 19

SECTION 5.

A. The net Profit and net Loss of the Company, including each item of income, gain, loss and deduction, and credit shall be allocated with respect to each Fiscal Year (or portion thereof) among the Members in accordance with their respective Interest.

B. Allocations for tax purposes shall be made in the same manner as the allocations set forth under Section 5(a); however the following adjustments shall be made and applied, to the extent necessary, in a manner consistent with Treasury Regulation Section 1.704-1(b):

(1) The allocations of income, gain, loss and deduction pursuant to Section 5(a) shall be adjusted to comply with the qualified income offset requirements of Treasury Regulation Section 1.704-1(b) and the nonrecourse deduction or minimum gain charge-back requirements of Treasury Regulation Section 1.704-2.

(2) The net Losses allocated pursuant to Section 5(a) shall not exceed the maximum amount of net Losses that can be so allocated without causing any Member to have a Deficit Capital Account at the end of any fiscal period. If some but not all Members would have Deficit Capital Accounts as a consequence of an allocation of net Losses pursuant to this Section 5(b)(ii), then the limitation set forth in this Section 5(b)(ii) shall be applied on a Member-by-Member basis so as to allocate the maximum permissible net Losses to each Member under Regulations Section 1.704-1(b)(2)(ii)(d). With respect to each allocation period thereafter, 100 percent of net Profit shall be allocated to the Members up to the aggregate of, and in proportion to, any net Losses previously allocated to each Member in accordance with this Section 5(b)(ii) in the reverse order in which such net Losses were allocated.

(3) Any special allocations pursuant to the preceding clause (i) required in order to comply with the Treasury Regulations shall be taken into account, to the extent permitted by the Treasury Regulations, in computing subsequent allocations pursuant to this Section 5(b) so that the net amount of any items so allocated and all other items allocated to each Member shall, to the extent possible, be equal to the amount that would have been allocated to each Member had there been no such special allocation.

Page 20

C. If there is a change in any Member's share of the distributions or other items of the Company during any Fiscal Year as a result of the Transfer (as defined herein) of an Interest (subject, in each case, to Article XI hereof), allocations among the Members shall be made in accordance with their respective Interests in the Company from time to time during such Fiscal Year in accordance with Code Section 706, using the closing-of-the-books method; however depreciation shall be deemed to accrue ratably on a daily basis over the entire year during which the corresponding asset is owned by the Company.

D. If the Internal Revenue Service successfully asserts an adjustment to the taxable income of a Member attributable to a transaction between the Member and the Company and, as a result of such adjustment, the Company is entitled to a deduction or reduction in income for Federal income tax purposes in excess of any gain recognized by the Company, such excess deduction shall be allocated to such Member or such reduced income shall be reflected in a reduction in income allocated to such Member. If the Internal Revenue Service successfully asserts an adjustment to the taxable income of the Company attributable to a transaction between the Member and the Company and, as a result of such adjustment, any Member is entitled to a deduction or reduction in income for Federal income tax purposes in excess of any gain recognized by such Member, the additional Company taxable income shall be allocated to such Member.

Notwithstanding anything to the contrary in this Section 5, the Tax Matters Member shall not take any of the actions described in this Section 5 without the prior approval of the Board, as required by Article XIII.

SECTION 6. Special Allocations. The special allocations described in Sections 7 through 12 of this Article shall be made in the same order as they appear in this Article VI.

SECTION 7. Minimum Gain Chargeback. Notwithstanding any other portion of this Article VI and except as provided in Section 1.704-2(f) of the Regulations, if there is a net decrease in the Company's minimum gain as determined under Sections 1.704-2(b)(2) and 1.704-2(d) of the Regulations during a taxable year of the Company, then the capital accounts of each member shall be allocated items of income (including gross income) and gain for such year (and, if necessary, for subsequent years) in an amount equal to the total net decrease in the Company's minimum gain multiplied by the members' percentage share of the Company's minimum gain at the end of the preceding taxable year determined in accordance with Section 1.704-2(g) of the Regulations. This Article VI, Section 7 is intended to comply with the minimum gain chargeback requirement of Section 1.704-2(f) of the Regulations and shall be

Page 21

interpreted consistently therewith. The items to be so allocated shall be determined in accordance with Sections 1.704-2(f)(6) and 1.704-2(j)(2) of the Regulations. In any taxable year that the Company has a net decrease in the Company's minimum gain, if the minimum gain chargeback requirement would cause a distortion in the economic arrangement among the members and it is not expected that the Company will have sufficient other income to correct that distortion, the Board may in its discretion (and shall, if requested to do so by a member) seek to have the Internal Revenue Service waive the minimum gain chargeback requirement in accordance with Regulation Section 1.704-2(f)(4).

SECTION 8. Chargeback of Minimum Gain Attributable to Member Nonrecourse Debt. Except as otherwise provided in Treasury Regulations Section 1.704-2(i)(4), notwithstanding any other provision of this Agreement, if there is a net decrease in Minimum Gain Attributable to Member Nonrecourse Debt during any Company Allocation Year, each member who has a share of the Minimum Gain Attributable to Member Nonrecourse Debt, determined in accordance with Treasury Regulations Section 1.704-2(i)(5), shall be specially allocated items of Company income and gain for such Allocation Year (and, if necessary, subsequent Allocation Years) in an amount equal to such member's share of the net decrease in Minimum Gain Attributable to Member Nonrecourse Debt, determined in accordance with Treasury 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. The items to be so allocated shall be determined in accordance with Treasury Regulations Sections 1.704-2(i)(4) and 1.704-2(j)(2). This Section is intended to comply with the minimum gain chargeback requirement in Treasury Regulations Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

SECTION 9. Qualified Income Offset. In the event any member unexpectedly receives any adjustments, allocations, or distributions described in Sections 1.704-1 (b)(2)(ii)(d)(4), (5), or (6) of the Regulations, which create or increase a Deficit Capital Account of such member, then items of Company income and gain (consisting of a pro rata portion of each item of Company income, including gross income, and gain for such year and, if necessary, for subsequent years) shall be specially allocated and credited to the Capital Account of such member in an amount and manner sufficient to eliminate, to the extent required by the Regulations, the Deficit Capital Account so created as quickly as possible. It is the intent that this Article VI, Section 9 be interpreted to comply with the alternate test for economic effect set forth in Section 1.704-1 (b)(2)(ii)(d) of the Regulations.

Page 22

SECTION 10. Gross Income Allocation. In the event any member would have a Deficit Capital Account at the end of any Company taxable year which is in excess of the sum of any amount that such member is obligated or deemed obligated to restore to the Company (1) pursuant to this Agreement, (2) under Regulations Section 1.704-2(g)(1) regarding Company minimum gain, and (3) under Regulations Section 1.704-2(i)(5) regarding member nonrecourse minimum gain, then the Capital Account of such member shall be specially allocated and credited with items of Company income (including gross income) and gain in the amount of such excess as quickly as possible.

SECTION 11. Allocation of Nonrecourse Deductions. Beginning in the first taxable year in which there are allocations of "nonrecourse deductions" (as described in Section 1.704-2(b) of the Regulations) attributable to nonrecourse liabilities of the Company, and thereafter throughout the full term of the Company, nonrecourse deductions shall be allocated to the members in accordance with, and as a part of, the allocations of Company net losses for such period subject to the preceding Section 3 of this Article.

SECTION 12. Allocation of Member Nonrecourse Debt Deductions. Items of Company loss, deduction and expenditures described in Section 705(a)(2)(B) of the Regulations which are attributable to any nonrecourse debt of the Company and are characterized as member nonrecourse debt deductions as determined under Section 1. 704-2(i)(2) of the Regulations shall be charged to the members' Capital Accounts in accordance with said Section 1.704-2(i) of the Regulations.

SECTION 13. Intention of Allocations. Any credit or charge to the Capital Accounts of the members pursuant to Sections 6 through 12 of this Article shall be taken into account in computing subsequent allocations of net profits and net losses pursuant to Sections 2 and 3 of this Article, so that the net amount of any items charged or credited to Capital Accounts shall to the extent possible, be equal to the net amount that would have been allocated to the Capital Account of each member if the special allocations required by Sections 6 through 12 of this Article hereof had not occurred.

Page 23

A. In accordance with Section 704(c)(1)(A) of the Code and Section 1.704-1(b)(2)(iv)(d)(3) of the Regulations, if a member contributes property with a fair market value that differs from its adjusted basis at the time of contribution, income, gain, loss and deductions with respect to the property shall, solely for federal income tax purposes, be allocated among the members so as to take account of any variation between the adjusted basis of such property to the Company and its fair market value at the time of contribution. Allocations pursuant to this Section 13A shall be made utilizing the remedial allocation method described in Treasury Regulation Section 1.704-3(d).

B. Pursuant to Section 704(c)(1)(B) of the Code, if any contributed property is distributed by the Company other than to the contributing member within seven years of being contributed, then, except as provided in Section 704(c)(2) of the Code, the contributing member shall be treated as recognizing gain or loss from the sale of such property in an amount equal to the gain or loss that would have been allocated to such member under Section 704(c)(1)(A) of the Code if the property had been sold at its fair market value at the time of the distribution.

C. In the case of any distribution of property (other than cash) by the Company to a member, such member shall be treated as recognizing gain in an amount equal to the lesser of:

(1) the excess (if any) of (A) the fair market value of the property received in the distribution over (B) the adjusted basis of such member's interest in the Company immediately before the distribution, reduced (but not below zero) by the amount of money received in the distribution, or

(2) the Net Precontribution Gain (as defined in Section 737(b) of the Code) of the member. The Net Precontribution Gain means the net gain (if any) which would have been recognized by the distributee member under Section 704(c)(1)(B) of the Code if all property which (A) had been contributed to the Company within seven years of the distribution, and (B) is held by the Company immediately before the distribution, had been distributed by the Company to another member.

Page 24

If any portion of the property distributed consists of property which had been contributed by the distributee member to the Company, then such property shall not be taken into account under this Article and shall not be taken into account in determining the amount of the Net Precontribution Gain. If the property distributed consists of an interest in a general partnership, limited partnership, limited liability company, corporation, joint venture, trust, business trust, cooperative, association or other such entity, then the preceding sentence shall not apply to the extent that the value of such interest is attributable to the property contributed to such entity after such interest had been contributed to the Company.

SECTION 14. Allocation of Income and Loss and Distributions in Respect of Interest Transferred. Distributions of Company assets may be made only to holders of Interests shown on the Company's books and records. Neither the Company, the Board, nor any member (who is not a recipient of such distribution) shall incur any liability for making distributions in accordance with the provisions of the foregoing, whether or not the Company, the Board, or the member has knowledge or notice of any transfer or purported transfer of ownership of a Company Interest which has not been effected in accordance with this Agreement. Notwithstanding any provision above to the contrary, the Company's gain or loss realized in connection with the sale or other disposition of any of the Company's assets shall be allocated solely to the holders of Company Interests as of the date the sale or other disposition occurs.

SECTION 15. Revaluation of Capital Accounts. In connection with a contribution of cash or other property (other than a de minimis amount) by a member or existing member as consideration for the member's interest in the Company, or in connection with the dissolution of the Company or a distribution of money or other property (other than a de minimis amount) by the Company, to a withdrawing member, as consideration for a membership interest, the Capital Accounts of the members shall be adjusted to reflect a revaluation of Company property (including intangible assets) in accordance with Regulation Section 1.704-1(b)(2)(iv)(f). If under Section 1.704-1(b)(2)(iv)(f) of the Regulations, Company property that has been revalued is properly reflected in the Capital Accounts and on the books of the Company at a book value that differs from the adjusted tax basis of such property, then depreciation, depletion, amortization and gain or loss with respect to such property shall be shared among the members in a manner that takes account of the variation between the adjusted tax basis of such property and its book value, in the same manner as variations between the adjusted tax basis and fair market value of property contributed to the Company are taken into account in determining the members' share of tax items under Section 704(c) of the Code.

Page 25

SECTION 16. Recapture. All recapture of income tax deductions resulting from sale or other disposition of Company property shall be allocated to the member or members to whom the deduction that gave rise to such recapture was allocated hereunder to the extent that such member is allocated any gain from the sale or other disposition of such property.

SECTION 17. Other Allocations.

A. For purposes of determining the net profits and net losses or other items allocable to any period, net profits, net losses and any 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. The members are aware of the income tax consequences of the allocations made hereunder and hereby agree to be bound by the provisions of this Agreement in reporting their shares of Company income and loss for income tax purposes.

C. To the extent permitted by Section 1.704-2(h)(3) of the Regulations, the Board shall endeavor to treat distributions 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 the Deficit Capital Account for any member.

ARTICLE VII - CONTRACTS, LOANS, CHECKS AND DEPOSITS

SECTION 1. Contracts. Subject to the conditions set forth in Article II, Section 7, the Board may authorize any officer or officers, agent or agents, to enter into any contract or execute and deliver any instrument in the name of and on behalf of the Company, and such authority may be general or confined to specific instances.

SECTION 2. Loans. No loans shall be contracted on behalf of the Company and no evidences of indebtedness shall be issued in its name unless authorized by the Board subject to the conditions set forth in Article II, Section 7. Such authority may be general or confined to specific instances.

Checks, Drafts, etc. All checks, drafts or other orders for the payment of money, notes or other evidences of indebtedness issued in the name of the Company shall be signed by such officer or officers, agent or agents of the Company and in such manner as shall from time to time be determined by Board.

The debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, will be solely the debts, obligations and liabilities of the Company, and no member, Manager, employee or agent of the Company will be obligated personally for any such debt, obligation or liability of the Company solely by reason of being a member or acting in the capacity as a Manager, employee or agent of the Company, except as provided under Article IX.

SECTION 2. Exculpation. Any Company Manager or officer exercising authorities or responsibilities for or on behalf of the Company shall not be personally liable to the Company for damages or for any breach of duty in that capacity, provided that nothing in this Article shall eliminate or limit the liability of any Manager or officer if a judgment or other final adjudication adverse to him or her establishes that his or her acts or omissions were in bad faith or involved willful misconduct or a knowing violation of law, or that he or she personally gained in fact a financial profit or other advantage to which he or she was not legally entitled.

ARTICLE IX - INDEMNIFICATION OF MANAGERS AND OFFICERS

To the fullest extent permitted by law, the Company shall indemnify and hold harmless any Manager or officer of the Company (collectively, the "Indemnitees") from and against any and all claims and demands whatsoever; provided that no indemnification will be made to or on behalf of any Indemnitee if a judgment or other final adjudication adverse to such Indemnitee establishes; (a) that his or her acts were committed in bad faith or were the result of active and deliberate dishonesty and were material to the cause of action so adjudicated, or (b) that he or she personally gained in fact a financial profit or other advantage to which he or she was not legally entitled. The provisions of this Article shall continue to afford protection to each Indemnitee regardless of whether he or she remains a Manager, officer, employee or agent of the Company. Indemnification shall be limited to the capital of the Company, except to the extent that such indemnification is covered by the proceeds of any insurance purchased by Company. No member shall be responsible for this indemnification obligation.

Page 27

The Company may be dissolved only upon the earlier of the following: (a) expiration of the Company's term or (b) a decision in writing by at least two-thirds of the members to dissolve the Company; or (c) as otherwise provided in the Act. After the Company has completed winding up its affairs and upon the filing with the State of Delaware of a Certificate of Cancellation the Company shall cease to carry on its business.

Accounting. Upon the occurrence of an event of dissolution, an accounting shall be made by the Company's independent accountants of the Company's accounts and of the Company's assets, liabilities and operations, from the date of the last previous accounting until the date of dissolution. The Board shall immediately proceed to wind up the Company's affairs.

Winding Up. If the Company is dissolved and its affairs are to be wound up, the Company shall continue solely for the purpose 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 or appropriate for winding up the Company's business and affairs. To the extent not inconsistent with the foregoing, all covenants and obligations in this Agreement shall continue in full force and effect until such time as the Company's property and assets have been distributed pursuant to this Agreement and the Certificate of Cancellation has been filed with the State of Delaware. The Board shall be responsible for overseeing the winding up and dissolution of the Company, shall take full account of the Company's liabilities and property, shall cause the property to be liquidated as promptly as is consistent with obtaining the fair value thereof (except to the extent the Board decides to distribute any assets to the members in kind), shall allocate any net profit and net loss resulting from such sales to the members as set forth in Article VI and shall cause the proceeds therefrom, to the extent thereof, to be applied and distributed in the following order:

Page 28

First, to the payment and discharge of all the Company's debts and liabilities to creditors, including any loans advanced by the members and all costs related to the dissolution, winding up, and liquidation and distribution of assets;
Second, to the establishment of such reserves as may reasonably be determined by the Board to be necessary to provide for the Company's contingent liabilities; and
The balance, if any, to the members, in proportion to the members' respective positive balances in their Capital Accounts, after giving effect to all contributions, distributions and allocations and adjustments for the Company's taxable year during which the liquidation occurs. Notwithstanding anything to the contrary contained herein, no member shall have an obligation to restore a negative balance in its Capital Account (or a Deficit Capital Account) upon winding up and dissolution of the Company.

C. Valuation of Distributable Assets. Assets may be distributed to members either in cash or in kind, as determined by the Board, with any assets distributed in kind being valued for this purpose at the fair market value at the date of dissolution as determined by the Board. In the event of the Company's dissolution, the Board may request an independent appraisal of the fair market value of the Company's assets. If such assets are distributed in kind, such assets shall be deemed to have been sold as of the date of dissolution for their fair market value, and the Capital Accounts shall be adjusted pursuant to this Agreement to reflect such deemed sale.

D. Termination; Compliance with Laws. Upon completion of the winding up, liquidation and distribution of the assets and the filing of the Certificate of Cancellation with the State of Delaware, the Company shall be deemed terminated. The Board shall comply with any applicable requirements of applicable law pertaining to the winding up of the Company's affairs and the final distribution of its assets.

Page 29

SECTION 3. Certificate of Cancellation. When all debts, liabilities and obligations have been paid and discharged or adequate provisions have been made therefor and all the remaining property and assets have been distributed to the members, a Certificate of Cancellation shall be executed in duplicate and verified by the person signing the Certificate, which Certificate shall set forth the information required by applicable law. Upon filing the Certificate of Cancellation with the State of Delaware, the Company shall cease to exist, except for the purpose of suits, other proceedings and appropriate actions pursuant to applicable law. The Board shall have authority to distribute any Company property discovered after filing of the Certificate of Cancellation with the State of Delaware, convey real estate and take such other action as may be necessary on behalf of and in the name of the Company.

SECTION 4. Return of Contribution Nonrecourse to Other Members. Except as provided by law, upon dissolution, each member shall look solely to the assets of the Company for the return of the member's capital contribution. If the Company property remaining after the payment or discharge of the Company's debts and liabilities is insufficient to return the cash contribution of one or more members, such member or members shall have no recourse against any other member or the Board.

ARTICLE XII - WAIVER OF NOTICE

Unless otherwise provided by law, whenever any notice is required to be given to any Company member or officer under the provisions of this Agreement or pursuant to the Company's Certificate of Formation, a waiver thereof in writing, signed by the person or persons entitled to such notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice.

ARTICLE XIII - TAX MATTERS

The members of the Company and the Company intend that the Company be treated as a partnership for all income tax purposes and will file all necessary and appropriate forms in furtherance of that position. The Board shall cause the preparation and timely filing of all tax returns required to be filed pursuant to the Code and all other tax returns deemed necessary in each jurisdiction in which the Company does business. Copies of such returns (including K-1 Forms or their equivalent), or pertinent information therefrom, shall be furnished to the members by March 15 each year after the end of the Company's Fiscal Year.

The Tax Matters Member may take any action contemplated by Sections 6222 through 6232 of the Code (inclusive); provided, however, that the Tax Matters Members shall not, without prior approval of the Board, (i) extend the statute of limitations on any income tax return of the Company; (ii) settle any income tax controversy; (iii) file a petition

in the United States Tax Court; or (iv) file a claim for refund.

(v) any other election the Tax Matters Member may deem appropriate and in the best interests of the members.

D. Code Section 754 Adjustments.

To the extent an adjustment to the adjusted tax basis of any Company property pursuant to Code Section 734(b) or Code Section 743(b) is required pursuant to Regulations Section 1.704-1(b)(2)(iv)(m)(2) or 1.704-1(b)(2)(iv)(m)(4) to be taken into account in determining Capital Accounts as the result of a distribution to a member in complete liquidation of its Interest, 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 allocated to the members in accordance with their interests in the Company in the event Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the member to whom such distribution was made in the event Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.
