(a)           Except as otherwise provided in this Section 4.4, all items of Company income, gain, loss, deduction and credit shall for federal and applicable state and local income tax purposes be allocated among the Members in the same manner as they share correlative Profits, Losses or Company items of income, gain, loss or deduction, as the case may be, for the Company taxable year.

12

allocations” are required under Regulations Section 1.704-3(a)(6), then solely for federal income tax purposes, subsequent allocations of income, gain, loss and deduction with respect to such asset (including income, gain, loss and deduction determined with respect to the alternative minimum tax) shall take account of any variation between the adjusted basis of such asset (including such adjusted basis for alternative minimum tax purposes) and its Gross Asset Value in the same manner as under Code Section 704(c) and the Regulations thereunder.

(c)           Any other elections or other decisions relating to allocations under this Section 4.4 shall be made by NASDI Holdings in any manner that reasonably reflects the purpose and intention of this Agreement; provided, however, unless NASDI Holdings otherwise selects another method, the Company shall utilize the “traditional method” (without currative allocations) for purposes of the allocation method under Regulations Section 1.704.3.

(a)           Except as otherwise provided in Article X, to the extent the Company has Available Cash Flow (other than from a Sale Transaction) for any calendar year as determined by the Board of Managers in accordance with the definition of Available Cash Flow contained herein, the Company shall distribute Available Cash Flow to the Class B Members in accordance with their Class B Percentage Interests not later than March 31st following the end of such calendar year.

(b)           Except as otherwise provided in Article X, to the extent the Company has Available Cash Flow from a Sale Transaction, as determined by the Board of Managers, the Company shall distribute the Available Cash Flow as follows:

(i)            first, to the Class A Members, pro rata in accordance with the Class A Percentage Interest, until the Class A Members have been distributed an aggregate amount under this Section 5.1(b)(i) equal to the Class A Liquidation Preference Amount;  and

(ii)           the balance, to the Class B Members, pro rata in accordance with their Class B Percentage Interest.

(c)           Notwithstanding Section 5.1(a), to the extent that a Member would be distributed, pursuant to such Section during any fiscal year, an amount in excess of the maximum amount which could be distributed to such Member without causing the Member otherwise to recognize gain under Code Section 731(a), then such distribution shall be, to the extent possible, an advance or draw (as described in Regulations Section 1.731-1(a)(1)(ii)) against such Member’s allocations of Profits and items of income and gain for the Company taxable year in which such distribution is made.

(d)           Immediately prior to any Sale Transaction, the Company shall distribute all Available Cash Flow (determined before giving effect to such Sale Transaction) in accordance with Section 5.1(a).

5.2           Tax Distributions.

(a)           Notwithstanding Section 5.1, the Company shall distribute on April 1, June 1, September 1, and December 1 of each year an amount equal to one quarter of the current calendar year Member Tax Distribution.  Each Member’s Member Tax Distribution shall equal the Applicable Tax Rate multiplied by the Net Taxable Income for the calendar year.  Subject to Section 5.2(b), the “Applicable Tax Rate” for any taxable year shall be forty percent (40%).  The “Net Taxable Income” of a Member for a taxable year shall be the taxable income of the Company allocated to such Member (excluding any Code Section 704(c) items in respect of contributed property) for such year (after being reduced by the amount by which taxable losses allocated to such Member under this Agreement for prior taxable years exceeds taxable income allocated to such Member under this Agreement in prior years).  Amounts distributed under this Section 5.2 shall constitute advances on amounts otherwise distributable under Section 5.1(a).  No distributions will be required under this Section 5.2 with respect to items of income or gain resulting from a Sale Transaction.

(b)           If the method for making estimated tax payments changes for federal income tax purposes, then NASDI Holdings may revise the timing of distributions under Section 5.2(b) to reflect such changes.  If NASDI Holdings determines in good faith that the highest effective combined federal, state, and local income tax rate for any calendar year applicable to the Members is higher or lower than forty percent (40%), then the Applicable Tax Rate shall be adjusted for such calendar year to reflect such highest effective combined rate; provided, however, the Applicable Tax Rate for each calendar year shall be the same for each Member.

5.3           Withholding.  If the Company is required by applicable law to pay any tax that is attributable to a Member (or a status of a Member), including, without limitation, federal or state withholding taxes, state personal property taxes, and state unincorporated business taxes, then such Member shall indemnify and reimburse to the Company an amount equal to such tax (including, without limitation, any interest or penalties associated with such tax).  The Company may offset distributions to any Member that such Member is entitled to under this Agreement against such Member’s obligation under this Section 5.3.  A Member’s obligation to indemnify and reimburse the Company shall survive the Member selling or disposing of its Interests in the Company and the termination, dissolution, liquidation, or winding up of the Company.

ARTICLE VI
MANAGEMENT POWER, RIGHTS AND DUTIES

6.1           Management.

(a)           Board of Managers.

(i)            The Company will be exclusively and completely managed by, and the powers of the Company shall be exercised by or under the authority of, a management board comprised of three (3) members (the “Board of Managers”).  The Class A Members shall be entitled to appoint not less than two (2) members of the Board of Managers (the “Class A Managers”), and, so long as ▇▇▇▇▇▇▇ or a Permitted Transferee of ▇▇▇▇▇▇▇ continues to be a Class B Member, such Class B Member shall have the absolute

14

right to appoint one member of the Board of Managers (the “▇▇▇▇▇▇▇ Manager”); provided, however, that the ▇▇▇▇▇▇▇ Manager shall, if other than ▇▇▇▇▇▇▇, be reasonably acceptable to the Class A Members.  In the event that ▇▇▇▇▇▇▇ or a Permitted Transferee of ▇▇▇▇▇▇▇ is no longer a Class B Member, then the Class A Members shall be entitled to appoint all three (3) members of the Board of Managers.  The number of members of the Board of Managers (each, a “Manager”) may be changed from time to time by vote of the Board of Managers.  Unless otherwise determined by the Board of Managers, the Managers will not be compensated for serving on the Board of Managers; provided, however, the Board of Managers may approve reimbursement for the actual reasonable expenses incurred by a Manager in performing such duties.

(ii)           Members of the Board of Managers shall initially consist of ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ and ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ (the Class A Managers) and ▇▇▇▇▇▇▇ (the ▇▇▇▇▇▇▇ Manager).  Except as otherwise set forth herein, each Manager will continue to serve as a Manager until such Manager’s death, resignation, or removal.

(iii)          The Class A Managers may only be removed by vote of the Class A Members.  The ▇▇▇▇▇▇▇ Manager may only be removed by vote of ▇▇▇▇▇▇▇ (or a Permitted Transferee thereof) (so long as ▇▇▇▇▇▇▇ or a Permitted Transferee of ▇▇▇▇▇▇▇ continues to be a Class B Member).  In the event that ▇▇▇▇▇▇▇ or a Permitted Transferee of ▇▇▇▇▇▇▇ is no longer a Class B Member, then the ▇▇▇▇▇▇▇ Manager may be removed by the Class A Members.

(iv)          A Manager may resign by providing written notice to the Board of Managers.  The resignation takes effect when received by the Board of Managers.  Any vacancy occurring in the Board of Managers, including vacancies resulting from an increase in size of the Board of Managers, or upon the death, resignation or removal of a Manager, shall be filled by the Class A Member; provided, however, that any vacancy resulting upon the death, resignation or removal of a ▇▇▇▇▇▇▇ Manager shall be filled by ▇▇▇▇▇▇▇ or a member of his Family, so long as ▇▇▇▇▇▇▇ (or a Permitted Transferee thereof) continues to be a Class B Member.

(b)           General Powers.  Except as otherwise provided herein, the Board of Managers, acting as a group, has the sole authority to manage and control the business, affairs and properties of the Company and is authorized to make any contracts, enter into any transactions, and make and obtain any commitments on behalf of the Company to conduct or further the Company’s business.  Upon approval of the Board of Managers, each Manager and any officer appointed pursuant to Section 6.1(d) is authorized to act for the Company to effectuate any action so approved.

(c)           Meetings of the Board of Managers.

(i)            The Board of Managers of the Company may hold meetings, both regular and special, either within or without the State of Delaware.  Managers may participate in such meetings in person or by teleconference.

(ii)           Regular meetings of the Board of Managers shall be held quarterly

15

without notice at such time and at such place as shall from time to time be determined by the Board of Managers.

(iii)          Special meetings of the Board of Managers may be called by a majority of the Managers on twenty-four (24) hours’ notice to each Manager, either personally or by mail, facsimile or confirmed e-mail, specifying the time, date and purpose of such special meeting.

(iv)          Minutes of each meeting of the Board of Managers shall be recorded and maintained along with a record of votes taken at each such meeting.

(v)           Each Manager shall have one (1) vote in all decisions of the Board of Managers.  Except for the matters set forth on Schedule II attached hereto which shall require the unanimous approval of the members of the Board of Managers and unless a greater number is otherwise required by law, the Certificate or this Agreement, action by the Board of Managers requires either (1) a resolution approved by the affirmative vote of at least a majority of the Managers present at a meeting of the Board of Managers with a quorum present (being at least a majority of the Managers then serving on the Board of Managers), or (2) a written action, signed by at least that number of Managers necessary to adopt a resolution at a properly called meeting attended by all the Managers entitled to vote on the matter.

(d)           Officers.

(i)            The Board of Managers may appoint officers of the Company in its sole discretion, which officers shall include a President, a Chief Executive Officer, a Chief Financial Officer, one or more Vice Presidents (the number thereof to be determined by the Board of Managers), a Treasurer, a Secretary, and such other officers including one or more Assistant Treasurers and Assistant Secretaries as the Board of Managers may determine (collectively, the “Officers”).  The Members agree to cause the Board of Managers to nominate and elect the following individuals as Officers of the Company from the date of this Agreement until their successors are chosen and qualified; and all officers of the Company shall hold office until their earlier death, resignation or removal:

(ii)           The Board of Managers may choose such other officers and agents as it shall deem necessary who shall hold their offices for such terms and shall exercise such powers and perform such duties as shall be determined from time to time by the

16

Board of Managers; and all officers of the Company shall hold office until their successors are chosen and qualified or until their earlier death, resignation or removal.  Any Officer may resign at any time upon written notice to the Company directed to the Board of Managers and the Secretary.  Such resignation shall take effect at the time specified therein, and unless otherwise specified therein no acceptance of such resignation shall be necessary to make it effective.  The Board of Managers may remove any Officer or agent with or without cause at any time by the affirmative vote of a majority of the Board of Managers.  Any such removal shall be without prejudice to the contractual rights of such Officer or agent, if any, with the Company, but the election of an Officer or agent shall not of itself create any contractual rights.  Any vacancy occurring in any office of the Company by death, resignation, removal or otherwise may be filled by the Board of Managers.  The salaries or other compensation, if any, of the Officers and agents of the Company shall be fixed from time to time by the Board of Managers.

(iii)          President.  The President shall preside at all meetings of the Board of Managers at which he or she is present, subject to the powers of the Board of Managers.  The President shall execute bonds, mortgages and other contracts, except where required or permitted by law to be otherwise signed and executed and except where the signing and execution thereof shall be expressly delegated by the Board of Managers to some other officer or agent of the Company.  The President shall have such other powers and perform such other duties as may be prescribed by the Board of Managers or as may be provided in this Agreement.

(iv)          Chief Executive Officer.  The Chief Executive Officer shall be the principal executive officer of the Company; shall, in the absence of the President, preside at all meetings of the Board of Managers at which he or she is present; subject to the powers of the Board of Managers and the President, shall have general charge of the business, affairs and property of the Company, and control over its officers, agents and employees; and shall see that all orders and resolutions of the Board of Managers are carried into effect.  The Chief Executive Officer shall execute bonds, mortgages and other contracts, except where required or permitted by law to be otherwise signed and executed and except where the signing and execution thereof shall be expressly delegated by the Board of Managers to some other officer or agent of the Company.  The Chief Executive Officer shall have such other powers and perform such other duties as may be prescribed by the Board of Managers, the President or as may be provided in this Agreement.

(v)           Chief Financial Officer.  The Chief Financial Officer of the Company shall, under the direction of the Board of Managers and the President, be responsible for all financial and accounting matters and for the direction of the offices of Treasurer and Controller.  The Chief Financial Officer shall have such other powers and perform such other duties as may be prescribed by the President or the Board of Managers or as may be provided by this Agreement.

(vi)          Vice Presidents.  Any Vice President in the order determined by the Board of Managers or by the President shall, in the absence or disability of the

17

President, act with all of the powers and be subject to all the restrictions of the President.  The Vice Presidents shall also perform such other duties and have such other powers as the Board of Managers, the President or this Agreement may, from time to time, prescribe.

(vii)         Secretary and the Assistant Secretaries.  The Secretary shall attend all meetings of the Board of Managers, all meetings of the committees thereof and record all the proceedings of the meetings in a book or books to be kept for that purpose.  The Secretary shall keep or cause to be kept, at the principal office of the Company or at the Secretary’s office, the records of the Company in which are contained the names of all Members and each such Member’s record address, and the Class A Percentage Interest or Class B Percentage Interest, as applicable, held by each.  Under the President’s supervision, the Secretary shall give, or cause to be given, all notices required to be given by this Agreement or by law; and shall have such powers and perform such duties as the Board of Managers, the President or this Agreement may, from time to time, prescribe.  The Assistant Secretary, or if there be more than one, the Assistant Secretaries in the order determined by the Board of Managers, shall, in the absence or disability of the Secretary, perform the duties and exercise the powers of the Secretary and shall perform such other duties and have such other powers as the Board of Managers, the President, or Secretary may, from time to time, prescribe.

18

(e)           Limitation on Authority of and Action by Members.  Except for a Person who is a Member and also a Manager or Officer, no Member shall be entitled to participate in or vote in matters involving the management or business of the Company, all such authority being vested in the Board of Managers.  No Member shall have authority, either express or implied, to bind the Company.  This Section 6.1(e) supercedes any authority granted to the Members pursuant to the Act.  Any Member who takes any action or binds the Company in contravention of this Section 6.1(e) shall be solely responsible for any loss and expense incurred by the Company as a result of the unauthorized action and shall indemnify, defend and hold the Company, the Managers, the Officers and the other Members harmless with respect to the loss or expense.

6.2           Voting or Other Actions by Members.

(a)           Unless otherwise specified in this Agreement, approval by or authorization of any action which requires a vote, consent, approval or action of or an election by a class of Members shall require the consent of Members holding in the aggregate a majority of the Interest of such class.

(b)           Unless otherwise specified by the Act or in this Agreement, the Class A Members shall have the sole right and power to vote on any matter submitted for the approval or consent of the Members, and the Class B Members shall have no right or power to vote in respect of such matters; provided, however, that if the Act or other applicable law gives the Class B Members the right to vote on any matter, then unless the Act or other applicable law requires otherwise, the Class A Members and the Class B Members shall vote as a single class.  Such vote may be taken at a meeting of the Members or by written consent in accordance with the provisions of Section 6.2(c).

(c)           Any action requiring the vote, consent, approval or action of or an election by the Members or required to be taken at a meeting of the Members may be taken without a meeting if a consent in writing, setting forth the action so taken, will be signed by Members holding at least the percentage of the Interests required for such approval, consent or action.

6.3           Transactions with the Company.  Any Member or any Affiliate thereof may lend money to, borrow money from, act as a surety, guarantor or endorser for, guaranty or assume one or more obligations of, provide collateral for or transact other business with the Company and derive and retain the profits therefrom; provided that, other than transactions contemplated by the Management Agreement, (i) any such contract, transaction, dealing or agreement is approved by the Board of Managers and (ii) such Member or Affiliate has made full and adequate disclosure to the Board of Managers with respect to all reasonably applicable information about such transactions or dealings with the Company.  The validity of any such transaction or dealing or any payment or profit related thereto or derived therefrom shall not be affected by any relationship between the Company and such Member or any of its Affiliates.  In any of these cases, dealings and undertakings between the Company and any Affiliate, Member or Affiliate of a Member may or may not be at arm’s length and on commercially reasonable terms.

19

6.4           Limited Liability.

(a)           Except as otherwise provided by the Act or in this Agreement, 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 no Manager, Officer or Member (or any Affiliate of a Manager, Officer or Member) shall be obligated personally for any such debt, obligation or liability of the Company solely by reason of being a Manager, Officer or Member of the Company.

(b)           To the extent that at law or in equity, a party shall have duties (including fiduciary duties) and liabilities to the Company or the Members, such duties and liabilities may be restricted by provisions of this Agreement.

(c)           To the fullest extent permitted under the Act, the Delaware General Corporation Law or any other applicable law as currently or hereafter in effect, none of the Board of Managers or any Manager, Officer or any Affiliate of any thereof shall be personally liable, responsible or accountable in damages or otherwise to the Company or any of its Members for or with respect to any action taken or failure to act on behalf of the Company within the scope of the authority conferred on such party by this Agreement or by law.  In addition to, and not by way of limitation of, the preceding sentence, none of the Board of Managers or any Manager, Officer or any Affiliate of any thereof shall be liable to the Company or its Members for monetary damages for breach of fiduciary duty as a Manager or Officer, except for liability for acts or omissions not in good faith or which involve gross negligence, intentional misconduct or a knowing violation of law.  Any repeal or modification of this Section 6.4 shall not adversely affect any right or protection of any Member existing prior to such repeal or modification.

(d)           The Board of Managers and each Member, Manager and Officer shall be fully protected in relying in good faith upon the records of the Company and upon such information, opinions, reports or statements presented to the Company by any Person as to the matters the Board of Managers or such Member, Manager or Officer reasonably believes are within such other Person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the Company, including information, opinions, reports or statements as to the value and amount of the assets, liabilities, profits, losses or net cash flow or any other facts pertinent to the existence and amount of assets from which distributions to the Member might properly be paid.

6.5           Indemnification.

(a)           Each Person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter, a “proceeding”), by reason of the fact that such Person, is or was a Member, Manager or Officer of the Company, or is or was serving at the request of the Company as a manager, director, officer, employee, fiduciary, or agent of another limited liability company or of a corporation, partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (each hereinafter and “indemnitee”) and whether the basis of such proceeding is alleged action in an official capacity as a member, manager, director, officer, employee or agent or in any other capacity while serving as a member, manager, director, officer, employee or agent, shall be indemnified and held harmless by the Company to the fullest

20

extent which it is empowered to do so unless prohibited from doing so by the Act, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than said law permitted the Company to provide prior to such amendment) against all expense, liability and loss (including attorneys’ fees actually and reasonably incurred by such Person and judgments, fines and amounts paid in settlement in connection with such proceeding) and such indemnification shall inure to the benefit of such indemnitee’s heirs, executors and administrators; provided, however, that, except as provided in Section 6.5(b), the Company shall indemnify any such Person seeking indemnification in connection with a proceeding (or part thereof) initiated by such Person only if such proceeding (or part thereof) was authorized by the Board of Managers of the Company.  The right to indemnification conferred in this Section 6.5 shall be a contract right and, subject to Sections 6.5(b) and 6.5(e), shall include the right to be paid by the Company the expenses incurred in defending any such proceeding in advance of its final disposition.  The Company may, by action of the Board of Managers, provide indemnification to employees and agents of the Company with the same scope and effect as the foregoing indemnification of Members, Managers and Officers.

(b)           Any indemnification of a Manager or Officer of the Company under Section 6.5(a) or advance of expenses under Section 6.5(e) shall be made promptly, and in any event within thirty (30) days, upon the written request of the Member, Manager or Officer; provided, however, that no payment of any indemnification claims shall be made prior to the approval of such payment by the Board of Managers.  If a determination by the Company that the Member, Manager or Officer is entitled to indemnification pursuant to this Section 6.5 is required, and the Company fails to respond within sixty (60) days to a written request for indemnity, the Company shall be deemed to have approved the request.  If the Company denies a written request for indemnification or advancing of expenses, in whole or in part, or if payment in full pursuant to such request is not made within thirty (30) days, the right to indemnification or advances as granted by this Section 6.5 shall be enforceable by the Member, Manager or Officer in any court of competent jurisdiction.  Such Person’s costs and expenses incurred in connection with successfully establishing his, her or its right to indemnification, in whole or in part, in any such action shall also be indemnified by the Company.  If shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any, has been tendered to the Company) that the claimant has not met the standards of conduct which make it permissible under the Act for the Company to indemnify the claimant for the amount claimed, but the burden of such defense shall be on the Company.  Neither the failure of the Company (including its Board of Managers, independent legal counsel, or its Members) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he, she or it has met the applicable standard of conduct set forth in the Act, nor an actual determination by the Company (including its Board of Managers, independent legal counsel, or the Members) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

(c)           The rights to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Section 6.5 shall not be exclusive of any other right which any Person may have or hereafter acquire under any

21

statute, provision of the Certificate, this Agreement, agreement, vote of the Members or disinterested Managers or otherwise.

(d)           The Company may purchase and maintain insurance on its own behalf or on behalf of any Person who is or was a Manager, Officer, employee, fiduciary or agent of the Company, or is or was serving at the request of the Company as a manager, director, officer, employee or agent of another limited liability company, corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss asserted against him or her in any such capacity, or arising out of his or her status as such, whether or not the Company would have the power to indemnify such Person against such expense, liability or loss under this Section 6.5.

(e)           Unless otherwise determined by the Board of Managers in a specific case, expenses incurred by any Person described in Section 6.5(a) in defending a proceeding shall be paid by the Company in advance of such proceeding’s final disposition upon receipt of an undertaking by or on behalf of the Member, Manager or Officer to repay such amount if it shall ultimately be determined that such indemnitee is not entitled to be indemnified by the Company.  Such expenses incurred by other employees and agents may be so paid upon such terms and conditions, if any, as the Board of Managers deems appropriate.

(f)            For purposes of this Section 6.5, references to “the Company” shall include, in addition to the resulting company, any constituent company (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its members, managers, directors, officers, and employees or agents, so that any Person who is or was a member, manager, director, officer, employee or agent of such constituent company, or is or was serving at the request of such constituent company as a member, manager, director, officer, employee or agent of another limited liability company, corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this Section 6.5 with respect to the resulting or surviving company as he, she or it would have with respect to such constituent company if its separate existence had continued.

ARTICLE VII
BOOKS AND RECORDS

7.1           Books and Records; Inspection by Members.  The Board of Managers shall keep (or cause to be kept) proper and usual books and records pertaining to the business of the Company.  The books and records of the Company shall be kept at the principal office of the Company or at such other places, within or without the State of Delaware, as the Board of Managers shall from time to time determine.  As provided by the Act, any Member or Manager of record shall have the right to examine, at any reasonable time or times for all purposes, the books and records of account, minutes and records of the Company and to make copies thereof.  Such inspection may be made by any agent or attorney of the Member or Manager, as applicable.

22

7.2           Tax Matters.

(a)           Unless otherwise provided herein, all elections and decisions required or permitted to be made by the Company under any applicable tax law shall be made by the Board of Managers (including the election under Code Section 6231(a)(1)(B)(ii) to have Code Section 6231(a)(1)(B)(i) not to apply (the “TEFRA Partnership Election”)).  The Board of Managers shall cause to be prepared and filed all necessary federal, state and local income tax returns on a timely basis.    Each Member shall furnish to the Company all pertinent information in its possession relating to Company operations that is necessary to enable the Company’s income tax returns to be prepared and filed.  Any balance sheet and capital account included in the preparation of the Company’s federal income tax return (and to the extent applicable, any state income tax return) will be based upon the Company’s method of accounting and principles under federal income tax law, rather than GAAP, Capital Account or other principles.

(b)           If the TEFRA Partnership Election is made, then for any applicable Company taxable year, NASDI Holdings is hereby designated the initial tax matters partner for the Company within the meaning of Code Section 6231(a)(7) (the “Tax Matters Partner”); provided, however, (i) in exercising its authority as Tax Matters Partner, the Tax Matters Partner will be limited by the provisions of this Agreement affecting tax aspects of the Company; and (ii) the Tax Matters Partner will give prompt notice to the Board of Managers of the receipt of any written notice that the Service or any state or local taxing authority intends to examine the Company income tax returns for any year, the receipt of written notice of the beginning of an administrative proceeding at the Company level relating to the Company under Code Section 6223, the receipt of written notice of the final partnership administrative adjustment relating to the Company pursuant to Code Section 6223, and the receipt of any request from the Service for waiver of any applicable statute of limitations with respect to the filing of any tax return by the Company.

(c)           Each Member acknowledges that this Agreement creates a partnership for federal and state income tax purposes, and hereby agrees not to elect under Code Section 761 or applicable state law to be excluded from the application of Subchapter K of Chapter 1 of Subtitle A of the Code or any similar state statute applicable to the Company.

(d)           No Member, Manager, Officer, agent or employee of the Company may file Service Form 8832 (or such alternative or successor form) to elect to have the Company be classified as a corporation for federal income tax purposes, in accordance with Regulations Section 301.7701-3 without the prior written consent of each of the Members.  Unless and until the Members elect to file such form electing to have the Company be classified as a corporation for federal income tax purposes, the Members shall take such other action as may be necessary or required (and permitted under the terms of this Agreement) to maintain the status of the Company as a partnership for federal income tax purposes.

7.3           Financial Records.  All financial records shall be maintained and reported using GAAP, except as set forth in Section 7.2(a).

7.4           Fiscal Year.  The fiscal year of the Company shall begin on the first day of January and end on the last day of December each year, unless otherwise determined by the Board of Managers.

ARTICLE VIII
TRANSFER OR ASSIGNMENT OF INTERESTS

8.1           Restrictions on Transfer; Certain Representations and Warranties.

(a)           Unless a Transfer of all or any portion of an Interest is made in accordance with the provisions of this Agreement, such Transfer shall not be valid or have any force or effect.

(b)           Each Member represents and warrants to the Company that such Member has acquired his, her or its Interest solely for such Member’s own account and not with a view to, or for resale in connection with, the distribution or other disposition thereof, and that the provisions of this Agreement and any Transfer of such Interest will be made only in compliance with all applicable federal and state securities laws.

8.2           Certain Permitted Transfers.  Notwithstanding anything contained in this Agreement to the contrary, Interests may be Transferred, subject to this Article VIII, including the last paragraph of this Section 8.2, as follows:
