          (e)          enter into, perform and carry out contracts of any kind;

          (f)          employ or otherwise engage employees, managers, contractors, advisors, attorneys, consultants and any other agents of the Company, and define their duties and pay reasonable compensation for such services; and

          (g)          do such other things and engage in such other activities related to the foregoing as may be necessary or incidental to the conduct of the Business or related to the Business, and have and exercise all of the powers and rights conferred upon limited liability companies formed pursuant to the Act.

           (a)            There shall be one class of ownership interest in the Company (referred to herein as the “Shares”) and, except as specifically set forth herein, each Member shall have the same relative rights, powers, and duties with respect to its Shares.

           (b)            The Company is authorized to issue Two Thousand (2,000) Shares.

           (a)            Except as provided in Section 5.2(b) or 5.2(c), no Member may sell, transfer, assign or pledge its Shares without the written consent of the other Members.  For purposes of this Agreement, a transfer of Shares shall include any transfer of a beneficial interest in the Shares or the granting of any lien or encumbrance on such Shares.  Any sale, transfer, assignment or pledge of Shares not permitted by this Article 5 will be void and of no effect.

           (b)            A Member may at any time transfer all, but not less than all, of its Shares to an Affiliate.  No transfer of Shares in reliance on this Section 5.2(b) will affect the Members’ rights or obligations under this Agreement, except as may be approved by the Board of Directors pursuant to Section 6.8.

          (c)            At any time after three (3) years after the date of this Agreement and during the term of this Agreement, a Member Group may transfer all, but not less than all, of its Shares to any Person without the prior written consent of the other Member Group if the transferring Member Group complies with the provisions of this Section 5.2(c):

              (i)          The transferring Member Group shall promptly give written notice (the “Notice”) to the Member Group of which it is not a member (the “Other Member Group”) at least sixty (60) days prior to the closing of the proposed transfer.  The Notice shall describe in reasonable detail the terms of the proposed transfer including, without limitation, (i) the number of Shares to be transferred (the “Offer Shares”), (ii) the date of the proposed transfer, (iii) the price and form of consideration to be paid, and (iv) the name and address of the prospective transferee.

              (ii)        Upon receipt of the Notice, the Other Member Group may elect to purchase all (but not less than all) of the Offer Shares, exercisable by the members of the Other Member Group in proportion to their Share ownership or as they may otherwise agree, at the price and on the terms specified in the Notice by delivering written notice of such election to the transferring Member Group within thirty (30) business days after the delivery of the Notice.  If the Other Member Group elects to purchase the Offer Shares from the transferring Member Group, the transfer of such Shares shall be consummated on or about the original proposed closing date set forth in the Notice, which shall not be more than sixty (60) business days following the receipt of the Notice.  To the extent the Other Member Group does not elect to purchase the Offer Shares, the transferring Member Group may consummate the proposed transfer on the terms set forth in the Notice.  Any transfer not on such terms, or effected more than one-hundred twenty (120) days following receipt of the Notice, shall not be permitted by this Section 5.2(c) unless the transferring Member Group again complies with all of the provisions hereof.

              (iii)       This Section 5.2(c) shall not apply to any transfer effected pursuant to the provisions of Section 5.2(b).  At any time prior to the closing of any transfer pursuant to this Section 5.2(c), the Other Member Group may make the demand under Section 5.3 and the process provided under Section 5.3 shall take precedence over the process provided in this Section 5.2.

          (d)        Upon any transfer of Shares permitted by this Section 5.2, the transferee shall be admitted as a Member of the Company (and as a Member of the transferring Member’s Member Group) pursuant to Article 12 only upon executing a joinder agreement in form and substance acceptable to the Board of Directors pursuant to which the transferee agrees to become bound by the terms hereof and assume all of the liabilities of the transferring Member under this Agreement.  Such transfer or assignment shall not discharge the transferring or assigning Member or Members from their obligations under this Agreement, unless the non-transferring or non-assigning Member Group hereto consents to such discharge.

          (a)         At any time after three (3) years after the date of this Agreement (or before such time but only as provided in Section 6.3(f)) and during the term of this Agreement, any Member Group (the “Terminating Group”) may demand that the other Member Group (the “Remaining Group”) either purchase all of the Terminating Group’s Shares, or sell all of its Shares to the Terminating Group.  Such right shall be exercised by the Terminating Group by providing written notice to the Remaining Group (the “Notice”), which Notice shall set forth the cash price and other terms upon which the Remaining Group shall either (i) sell its Shares to the Terminating Group (pro rata to the Terminating Group’s Members in proportion to their share ownership or as the Terminating Group may otherwise agree) or (ii) purchase the Terminating Group’s Shares (pro rata by the Remaining Group’s Members in proportion to their Share ownership or as the Remaining Group may otherwise agree).  In no event shall the cash price offered by the Terminating Group be less than the price calculated in accordance with the formula provided on attached Exhibit 5.3.  The Remaining Group shall elect either to sell its Shares to the Terminating Group or to purchase the Terminating Group’s Shares within the “Period” (as defined below); provided that if the Remaining Group shall make no election within the Period, it shall be deemed to have elected to sell its Shares to the Terminating Group.  For purposes of this Agreement, the “Period” means 30 days after the date the Notice is given pursuant to Section 14.1(c). The closing of any sale of Shares pursuant to this Section 5.3 shall occur within 60 days after the end of the Period, on a date specified by the purchasing Remaining Group; provided that if the Remaining Group desires to finance the purchase of the Shares, it may extend the closing for up to an additional 15 days (i.e., to 75 days after the end of the Period) and may condition the closing on its ability to obtain financing.  If the closing does not occur for failure of the Remaining Group to obtain financing, such event will be treated as an election by the Remaining Group to sell its Shares to the Terminating Group.  At the closing, (i) the purchase price shall be paid in full by cash or by certified or bank check, and (ii) the selling Member Group shall deliver the certificate(s) for its Shares duly endorsed for transfer to the purchasing Member Group or accompanied by executed stock powers endorsed to the applicable purchasing Members; such certificate(s) shall also be accompanied by any other documents that are necessary to transfer to the applicable purchasing Members good title to the Shares being purchased.

          (b)         If the purchaser of Shares in a transaction under this Section 5.3 defaults in payment of the purchase price set forth in the Buy-Sell Notice, the seller of such Shares, by notice to such purchaser within 10 days after such default has occurred, may terminate the agreement for the sale of the Shares to the purchaser and the seller, by notice to the purchaser, may elect to purchase, or designate some other person or entity to purchase, the Shares held by the purchaser at a price which is 20% lower than the Buy-Sell Price and on the payment terms set forth therein. If the seller makes such an election, the transaction must be completed on or before the thirtieth (30th) day after the seller transmits notice of such election to the purchaser (subject to extension by mutual agreement of the Terminating Member and the Remaining Member). The rights of the seller under this Section 5.3 (b) are in addition to any other rights that it may have under this Agreement or other wise as a result of a default of the purchaser.

          (c)         If a transaction under this Section 5.3 is to occur, the seller in such transaction may, upon notice to the purchaser and the Company, require that all financial obligations of the Company to such seller and its affiliates be satisfied in connection with such acquisition, whether or not otherwise due and payable. For this purpose, a financial obligation means any debt of the Company (other than trade payables in the ordinary course of business and not yet due) and any contingent obligation in respect of debt of the Company (such as would exist if the seller guaranteed borrowings by the Company from a third party). Any outstanding indebtedness for borrowed money shall be satisfied either by payment from the Company or purchase by the purchaser or its designee of the obligation, in either case at the outstanding principal amount thereof plus interest accrued (but unpaid) through the date of payment. A contingent financial obligation shall be satisfied by a release of the seller or an indemnity or other arrangement reasonably satisfactory to the seller, including but not limited to an indemnity any for secondary pension withdrawal liability that may exist on the part of the seller.

          (d)         As of the closing date of a transaction referred to in this Section 5.3, the seller in such transaction shall enter into a customary non-competition agreement with the buyer in such transaction restricting the seller from competing with the Business within the State of Michigan for a period of five (5) years after such closing date.

          (a)             Regular quarterly meetings of the Board of Directors shall be held, without notice and without the necessity of a written agenda, within 45 days after the beginning of each fiscal quarter according to an annual schedule prepared and distributed by the Chairman at least ten business days prior to the first quarterly meeting of each fiscal year or as otherwise scheduled by the Board, for review of all significant matters relating to the Company’s business.

          (b)           All meetings of the Board of Directors shall be held at the principal office of the Company, or at such other place as shall be designated in a Meeting Notice (as defined in Section 6.3(d)), at such times as shall be designated from time to time in a Meeting Notice (as hereinafter defined).  Meetings of the Board of Directors shall be presided over by a Chairman, to be appointed as set forth in Section 6.2.  All significant planning and strategy matters relating to the Company will be brought before the Board of Directors.  No action shall be taken by the Board of Directors without the affirmative vote of at least a majority of the Board of Directors present at a meeting duly called and held (in person or by telephone) at which a quorum is present.  Notwithstanding the foregoing, any decision of the Company (i) to pursue any USC Member’s indemnification obligations to the Company or to enforce the Guaranty (as defined below) or (ii) not to retain the real property (the “Sale Property”) that is subject to the contractual rights and obligations summarized in that certain memo from ▇▇▇▇▇ ▇▇▇▇▇ to ▇▇▇▇▇ ▇▇▇▇▇▇ dated June 15, 2003 with respect to the Grand Ledge and Lake Lansing properties upon a third-party offer to purchase such property (so long as the purchase price of such property is not above 3,750,000), will require the affirmative vote of the two Levy Representatives and not a majority of the Board of Directors; provided that upon a third-party purchase of the Sale Property, BWB, Inc. of Michigan (or another Member designated by the USC Group) will be entitled to receive the proceeds of the sale unless the Company has assumed the obligations summarized in the memo to remit the net proceeds of the sale to the original owners of the Sale Property.  The attendance (in person or by telephone) of a majority of the Representatives of the Board of Directors that include at least one USC Representative and one Levy Representative shall constitute a quorum; provided that if a Representative does not appear at a meeting (and, if a special meeting, has been given a Meeting Notice), and the proposed meeting is adjourned for failure of a quorum, and the same Representative again does not appear (and, if a special meeting, has been given a Meeting Notice for the rescheduled meeting), then such Representative shall be deemed present at the rescheduled meeting for purpose of determining whether a quorum is present.  Significant Transactions (as defined is Section 6.8) will require the affirmative vote of a four-fifths (4/5) majority of the Board of Directors.

          (c)           Representatives on the Board of Directors may participate in any regular or special meeting of the Board of Directors telephonically or through other similar communications equipment, as long as all of the Representatives participating in the meeting can hear one another.  Participation in a meeting pursuant to the preceding sentence shall constitute presence in person at such meeting for all purposes of this Agreement.

          (d)           Any Representative may call a special meeting of the Board of Directors upon at least three (3) business days prior written notice (the ‘‘Meeting Notice”), which Meeting Notice shall be given no more than thirty (30) days before the proposed meeting date, and which shall include a proposed agenda for the meeting.  The requirement of a Meeting Notice may be waived by a Representative in writing or by attendance (unless such attendance is solely for the purpose of objecting to the failure to provide a Meeting Notice).  Additional matters may be added to the proposed agenda for any special meeting by any Representative upon written notice to the other Representatives, provided such notice is given at least three (3) business days before the proposed special meeting, or such lesser period that is affirmatively agreed to by a majority of the Representatives.

          (e)           Any action required or permitted to be taken at a regular or special meeting of the Board of Directors may be taken without a meeting by unanimous written consent, which consent shall set forth the actions to be so taken.  Any such writing or writings shall be filed with the minutes of the proceedings of the Board of Directors.  Any such unanimous written consent shall be the approval of the Board of Directors as if such action was taken at a properly called and constituted meeting of the Board of Directors at which all of the Representatives were present and voting.

          (f)            In the event of a disagreement among the Board of Directors or the Members regarding any dispute wherein (i) the solvency of the Company would be reasonably expected to be threatened, or (ii) the ability of the Company to operate as a going concern would reasonably be expected to be materially adversely affected (any such disagreement being referred to herein as a “Dispute”), the Members shall negotiate in good faith to resolve the disagreement.

          (g)            A Representative may appoint another Representative to vote or otherwise act for him at any regular or special meeting of the Board of Directors by signing a proxy appointment form and delivering it to the individual so appointed.  Unless otherwise provided in the proxy, any proxy may be revoked at any time prior to the vote pursuant to such proxy by written notice delivered to the Company.  Representatives attending by proxy shall be counted for purposes of establishing a quorum.

          (a)            Approval of an annual operating budget that projects earnings before tax below five (5%) percent of sales.

          (b)            Approval of a capital budget that exceeds one hundred fifty (150%) percent of annual budgeted depreciation expense.

          (c)            Incurrence of indebtedness that results in a debt to equity ratio in excess of 1.75 to 1.0.

          (d)            A distribution to the Members by way of dividend or otherwise in any one fiscal year except as provided in Section 8.4(a).

          (e)            Conducting any business other than the Business.

          (f)            The sale, transfer or issuance, other than as set forth in Section 8.2, or repurchase by the Company of Shares or other ownership interests in the Company, including any options, warrants or other interests representing or convertible into an ownership interest or a right to obtain an ownership interest in the Company.

          (g)            Entering into any guarantees or indemnities (except for indemnities to third parties entered into in the ordinary course of business) for the benefit of any Member or third party.

          (h)            Any acquisition of a business, whether by merger, consolidation, or acquisition of equity or assets, or joint venture or any investment in a business.

          (i)            The sale of over $5,000,000 or of five percent (5%) of the assets of the Company in a single transaction or series of related transactions.

          (j)            The merger or consolidation or corporate reorganization, liquidation or dissolution of the Company or the commencement of any such proceeding under any bankruptcy, insolvency or similar law.

          (k)            Any transaction or dealing with any Member or any affiliate of a Member.

          (l)            The determination that the Company requires an additional capital contribution from the Members or the approval of a convertible loan facility provided by a Member in accordance with Section 8.2.

          (m)            Any issuance of Shares by the Company that would result in a Member owning more than 60% of the issued and outstanding Shares.

          (n)            Any decision with respect to the payment of a pension withdrawal liability.

          (o)            The right to waive the requirements under Section 5.2(b) of this Agreement.

          (q)            Any amendment to the Articles of Organization of the Company.

          (a)             The Board of Directors may appoint such officers at such time, for such term, with such power and authority and for such compensation and other benefits (if any), all as the Board of Directors shall determine in its discretion.  The officers of the Company shall initially include a President, Secretary and a Treasurer.  Each such officer shall hold office for the term for which such officer is appointed.  Any individual may hold any number of offices.

          (b)             Subject to applicable law and any applicable contractual relationships, officers may be removed at any time with or without cause by the Board of Directors.

          (c)             Each officer of the Company will have the authority normally associated with the position, subject to any specific delegation of authority and duties made to such officer by the Board of Directors pursuant to this Section 7.1.

          (a)            The Members may, but shall not be required to, make additional capital contributions to the Company.  If the Board of Directors determines that the Company requires additional capital, the Members will be requested to make additional capital contributions in proportion to their Share ownership.  If either Member Group does not provide such funding, the other Member Group may, but is not required to, contribute the shortfall, exercised by the Members of such Member Group in proportion to their Share ownership or as they may otherwise agree.  After all additional capital is contributed, additional Shares shall be authorized and issued to the Members as necessary so that the Shares held by each Member shall be proportional to each Members aggregate capital contributions as a fraction of the total aggregate capital contributions of all Members; provided, however, the Member Group contributing such funding may, instead of providing such funding in exchange for additional Shares, elect to provide such funding to the Company in the form of a convertible loan facility on terms and conditions satisfactory to such Member Group and the Board of Directors.

          (b)            Notwithstanding any term or provision in this Agreement to the contrary, each Member shall have the right to contribute additional assets located in Michigan relating to the Business in exchange for additional Shares.  In no event, however, shall such contributing Member’s ownership interest in the Company exceed 60%.

          (a)             No Member shall be entitled to demand the return of its capital contributions prior to the dissolution and winding-up of the Company.

          (b)             The Members shall not receive any interest, salary or draw with respect to their capital contributions or for services rendered to or on behalf of the Company or otherwise in their capacity as Members, except as otherwise specifically agreed in a writing executed by all Members.

          (a)             Distributions shall be made to the Members at the times and in the aggregate amounts determined by the Board of Directors.  Any distributions shall be made in the following manner and order of priority:

                 (i)          First, to the Members to the extent of any Undistributed Profits allocated to them, in the order of priority allocated to them (i.e., distribution of Undistributed Profits on a “first in, first out” basis); and

                 (ii)        Then, to the Members pro rata, in accordance with their Shares.

          (b)             Notwithstanding the foregoing, the Company shall make minimum distributions to each Member during or as soon as practicable following the end of each fiscal year in an amount equal to the taxable income allocated to such Member under Section 9.3 for such fiscal year multiplied by the highest marginal tax rates applicable to individuals residing in the State of Michigan, provided such minimum distributions shall be treated as advances of future distributions otherwise required by this Section 8.4(a).

          (c)             Notwithstanding any provision to the contrary contained in this Agreement, the Company shall not make a distribution to a Member if (i) such distribution would cause the Company to be in default under or in violation of any agreement, (ii) after such distribution the Company would not have sufficient cash to operate its business or (iii) such distribution would violate Section 307 of the Act or other applicable law.

          (a)             The Company’s profit or loss for each fiscal year shall be determined in accordance with generally accepted accounting principles as applied in the United States, provided, however, that in no event shall any expense or loss which is reimbursed or reimbursable to the Company, or against which the Company is indemnified, by any Member or Affiliate of a Member pursuant to this Agreement or any other agreement to which such Member or Affiliate is a party be taken into account (but, rather, any such loss or expense shall be disregarded) in determining such profit or loss.

          (b)             Subject to Sections 9.1(e) and 9.1(f) below, profit for each fiscal year, determined in accordance with Section 9.1(a), shall be allocated between the Members as follows:

                 (i)          the first $2,100,000 of profit for the fiscal year ending December 31, 2007, shall be allocated to the members of the USC Group pro rata based upon their Shares, and the balance of the profit for such fiscal year shall be allocated among the Members pro rata based upon their Shares;

                 (ii)         profit for any subsequent fiscal year shall be allocated first, pro rata, in proportion to and to the extent of (so as to offset) any losses allocated pursuant to Section 9.1(c) below in any prior fiscal year, in reverse of the order that such losses were allocated, and the balance of any such profits shall be allocated as follows:

               (A)          the balance of any such profit for the first year ending December 31, 2008, shall be allocated first to the members of the USC Group (pro rata based upon their Shares) to the extent, and up to the amount, of $750,000, and any remaining profit for such fiscal year shall be allocated among the Members pro rata based on their Shares;

               (B)          the balance of any such profit for the fiscal year ending December 31, 2009, shall be allocated first to the members of the USC Group (pro rata based upon their Shares) to the extent, and up to the amount, of $750,000, and any remaining profit for such fiscal year shall be allocated among the Members pro rata based on their Shares; and

               (C)          the balance of any such profit for any subsequent fiscal year shall be allocated among the Members pro rata based on their Shares.

          (c)             Subject to Sections 9.1(e) and 9.1(f) below, loss for each fiscal year, determined in accordance with Section 9.1(a), shall be allocated among the Members as follows:

                (i)          First, pro rata, in proportion to and to the extent of (so as to offset) any Undistributed Profits from any prior fiscal year(s), in reverse of the order that such Undistributed Profits were allocated, and

                (ii)         the balance of any losses shall be allocated between the Members pro rata, based on their Shares.

          (d)          To the extent that any profit is allocated so as to offset any loss (or vice versa), such profit and loss shall be disregarded for purposes of thereafter applying the provisions of this Section 9.1 and those of Section 8.4 and in the definition of Undistributed Profits.

          (e)             The parties anticipate that the Company will (directly or through one or more of the Superior Subsidiaries) earn rebates pursuant that certain Cement Rebate Agreement of even date, and that such rebates will generally be taken into account in determining the Company’s annual profit or loss.  In applying the provisions of Sections 9.1(b)(i) and 9.1(b)(ii)(A) and (B), however, the parties intend that such rebates be allocated among the Members based on their Shares before the balance of any profit is allocated.  For example,

(i)          if for the fiscal year ending December 31, 2007, such rebates amount to $400,000, and total profit (determined before taking such rebates into account) is $1,700,000, then (A) $1,700,000 (rather than $2,100,00) of profit would be allocated to the members of the USC Group (pro rata based upon their Shares), (B) the balance of the profit (i.e., the $400,000 of rebates) would be allocated among all of the Members based on their Shares, and (C) Levy would be required to make a payment to the USC Group of $160,000 pursuant to Section 9.1(g) below, but would be entitled to a distribution of $160,000 at such time as the Undistributed Profits for such fiscal year were distributed, and

(ii)          if for the fiscal year ending December 31, 2008, such rebates amount to $400,000, and total profit (determined before taking such rebates into account) is $350,000, then $350,000 (rather than $750,00) of profit would be allocated to the members of the USC Group (pro rata based upon their Shares), and the balance of the profit (i.e., the $400,000 of rebates) would be allocated among all of the Members based on their Shares.

          (f)          In the event that any goodwill contributed by a Member is impaired, any deduction from or charge against profit or loss for such impairment shall be specially allocated to such Member, and such allocation shall (on a dollar for dollar basis) decrease the profit, or increase the loss, which would otherwise be allocated to such Member.  For example, if a USC Member were to contribute $3 million of goodwill, and such goodwill were to become completely impaired in a subsequent year for which the profit allocable to such USC Member (determined before the application of this paragraph) were $3 million, then such USC Member would be allocated no profit (or loss) for such fiscal year.  No deduction for impairment allocated to any USC Member shall be taken into account, however, for purposes of applying the provisions of Section (g) below and; accordingly, no such deduction shall give rise to (or increase) any obligation of Levy to make a payment to such USC Member pursuant to Section 9.1(g) below.  In addition, the parties acknowledge that the USC Group is contributing, among other assets, prepaid licenses for certain vehicles which may, in the hands of the Company or a Superior Subsidiary, have to be re-licensed.  If, by reason of the re-licensing of any such vehicles or for any other reason, the prepaid licenses contributed by the USC Group become impaired, worthless or the like, then any resulting deduction from or charge against profit or loss shall be specially allocated to the USC Group, and such allocation shall (on a dollar for dollar basis) decrease the profit, or increase the loss, which would otherwise be allocated to the USC Group (but, as with any deduction for impairment of goodwill specially allocated to the USC Group, any deduction or charge for impairment, worthlessness or the like of any such prepaid license shall not be taken into account for purposes of applying the provisions of Section (g) below and; accordingly, shall not give rise to (or increase) any obligation of Levy to make a payment to the USC Group (or any USC Member) pursuant to Section 9.1(g) below).

          (g)             In the event that the aggregate allocation of profit of the Company to the USC Group for the Company’s fiscal year ending December 31, 2007, is less than $2,100,000, Levy agrees to pay the USC Group (pro rata to the USC Members in proportion to their respective Share ownership) an amount equal to the lesser of (i) forty (40%) percent of the difference between $2,100,000 and the amount of profit allocated to the USC Group for such fiscal year and (ii) $840,000.  Any such payment shall be treated, for federal income tax purposes, as a contribution by Levy to the Company’s capital and a guaranteed payment by the Company to the USC Group for the use of capital within the meaning of Section 707(c) of the Code, the deduction for which shall be allocated to Levy for such tax purposes.  There shall be no net credit or debit to Levy’s capital account on account of such payment (and/or on account of any deemed contribution and deduction resulting therefrom), which shall be disregarded in determining profit or loss under this Section 9.1.  Such payment will be made within 60 days after the end of the fiscal year.

          (a)             The Company shall maintain for each Member a capital account to which such Member’s capital contributions, and any profits allocated to such Member, shall be credited, and against which distributions to such Member, and any losses allocated to such Member, shall be charged.  The profits and losses to be taken into account in maintaining the Members’ respective capital accounts shall be determined in accordance with Section 9.1 above.

          (b)             No Member shall have any obligation to restore any negative balance in such Member’s capital account.

Section 9.3          Allocations Solely for Tax Purposes.

          (a)             Each item of income, gain, loss or deduction entering into the computation of the Company’s profit and loss as determined for federal income tax purposes shall be allocated among the Members in the same proportions as the corresponding items are allocated for capital accounting (“book”) purposes, except as provided below in this Section 9.3.

          (b)             Income, gain, loss and deduction with respect to any property (other than cash) contributed to the capital of the Company shall, solely for tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis to the Company of the property for federal income tax purposes and such property’s fair market value at the time of such contribution in the following manner, or in such other manner as the Board may choose.  Any depreciation or amortization for income tax purposes of any asset contributed by a Member shall be allocated to such Member and, on sale or other taxable disposition of any such asset, (i) gain shall be allocated to such Member except to the extent that the “amount realized” (within the meaning of Section 1.1001-1(a) of the Treasury Regulations) on such sale or other disposition exceeds the fair market value of such asset at the time of contribution to the Company and (ii) loss shall be allocated to such Member except to the extent that the fair market value of such asset at the time of contribution to the Company exceeds the “amount realized” (within the meaning of Section 1.1001-1(a) of the Treasury Regulations) on such sale or other disposition.

          (c)             Allocations pursuant to this Section 9.3 are solely for tax purposes, and shall affect neither the capital accounts of, nor any distributions to, the Members.

          (a)          adopting the calendar year as the Company’s fiscal year;

          (b)          an election pursuant to Code Section 754.

          (a)          the Members’ unanimous agreement to dissolve;

          (b)          the arbitrator’s or arbitration committee’s, pursuant to Section 6.3(f), decision to dissolve;

          (c)          the entry of a decree of judicial dissolution under Section 801(d) of the Act; or

          (d)          the sale, exchange or disposition of all or substantially all of the assets of the Company.

          (a)               Jurisdiction; Service of Process.  Legal proceedings commenced by any party hereto arising out of any of the transactions or obligations contemplated by this Agreement shall be brought exclusively in the federal court in Detroit, Michigan, or in the absence of federal jurisdiction in Oakland County Circuit Court in Michigan.  The parties hereto irrevocably and unconditionally submit to the jurisdiction of such courts and agree to take any and all future action necessary to submit to the jurisdiction of such courts.  The parties hereto irrevocably waive any objection that they now have or hereafter may have to the venue of any suit, action or proceeding brought in any such court and further irrevocably waive any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.  Final non-appealable judgment against any party hereto in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment, a certified or true copy of which shall be conclusive evidence of the fact and the amount of any indebtedness or liability of the party therein described, or by appropriate proceedings under any applicable treaty or otherwise.

          (b)              Governing Law.  This Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of Michigan, without giving effect to conflicts of law principals.

          (d)                Assignment.  Except as otherwise provided in Section 5.2 and this Section 14.1(d), neither party hereto will transfer or assign any right, obligation or remedy under this Agreement.  Any transfer or assignment not permitted by this Section 14.1(d) will be void and of no effect.  Except as otherwise set forth in Section 5.2, any party hereto may at any time transfer or assign any right, obligation or remedy under this Agreement to an Affiliate under common control with such party hereto provided that, at the time of such transfer, the transferee shall agree in writing to be bound by all applicable terms of this Agreement; provided, however, that such transfer or assignment shall not discharge the transferring or assigning party from its obligations under this Agreement unless the non-transferring or non-assigning party hereto consents to such transfer or assignment. No transfer or assignment in reliance on this Section 14.1(d) will affect the parties’ rights or obligations under this Agreement, except as may be otherwise agreed by the parties in writing.

          (f)                Counterparts.  This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, and all of which together shall constitute one and the same instrument.

          (g)                Headings.  Headings in this Agreement are for reference purposes only and shall not be deemed to have any substantive effect.

          (h)                Attorneys’ Fees.  In the event that any action or proceeding, including arbitration, is commenced by any party hereto for the purpose of enforcing any provision of this Agreement, the parties to such action, proceeding or arbitration may receive as part of any award, judgment, decision or other resolution of such action, proceeding or arbitration their costs and reasonable attorneys’ fees as determined by the person or body making such award, judgment, decision or resolution.  Should any claim hereunder be settled short of the commencement of any such action or proceeding, including arbitration, the parties in such settlement shall be entitled to include as part of the damages alleged to have been incurred reasonable costs of attorneys or other professionals in investigating or counseling on such claim.

          (i)                Severability.  Any provision of this Agreement which is invalid, illegal or unenforceable in any jurisdiction will, as to that jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability, without affecting in any way the remaining provisions hereof in such jurisdiction or rendering that or any other provision of this Agreement invalid, illegal or unenforceable in any other jurisdiction.

          (j)                Third Parties.  Nothing in this Agreement, express or implied, is intended to confer upon any party, other than the parties hereto and their respective successors and permitted assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement.

          (k)               Drafting Presumption. The parties hereto agree that they participated in the drafting of this Agreement and, in the event that any dispute arises in the interpretation or construction of this Agreement, no presumption shall arise that either one party or the other drafted this Agreement.

          (a)            Except as necessary to comply with applicable law or contract, and subject to any applicable privileges (including the attorney-client privilege), each Member shall, upon reasonable prior notice, be given reasonable access to the Company’s employees, agents, properties, books and records during normal business hours.  The Company will prepare and deliver such financial or other information concerning its business as either Member may reasonably request.

          (b)            The Company will furnish to each Member, upon request, as promptly as practicable, such information and assistance as is reasonably necessary for the filing of each Member’s tax returns, the making of any election related to taxes, the preparation for any audit by any tax authority, and the prosecution or defense of any claim, suit or proceeding relating to any tax return.

          (a)                The Company and each Member shall have the rights set forth in this Section 14.5 with respect to Company Opportunities.  Neither the Company nor any Member or Affiliate thereof shall take any actions with respect to a Company Opportunity except in compliance with this Section 14.5.

          (b)                In the event that any Member or its Affiliates become aware of a Company Opportunity (other than an Ancillary Transaction, as defined in Section 14.5(c)) that such Member or such Member’s Affiliate desires to pursue, such Member (the “Proposing Member”) shall notify the Member Group of which it is not a member (the “Deciding Member Group”) in writing (an “Opportunity Notice”) thereof. Upon delivery of the Opportunity Notice, the Deciding Member Group shall have the sole right to elect whether the Company shall pursue the Company Opportunity.  The Deciding Member Group shall have thirty (30) days after receipt of an Opportunity Notice to notify the Proposing Member of the Company’s desire to pursue the Company Opportunity (the “Response”).

                 (i)          If the Deciding Member Group delivers a Response that the Company elects to pursue the Company Opportunity, then the Company shall use its best efforts to (A) enter into good faith negotiations regarding the Company Opportunity within fifteen (15) days after the Deciding Member Group’s receipt of the Opportunity Notice, and (B) negotiate the terms of and consummate the transaction contemplated by the Company Opportunity within one-hundred fifty (150) days after the Deciding Member Group’s receipt of the Opportunity Notice, or such longer period as is practical under the circumstances.  In such event, neither any Member nor any Affiliate thereof shall pursue the Company Opportunity individually.

                 (ii)          If the Deciding Member Group delivers a Response that the Company elects to forego the Company Opportunity, the Company shall not pursue the Company Opportunity. In such event, the Proposing Member or any Affiliate thereof shall be free to pursue the Company Opportunity.

          (c)                In the event that a Member or its Affiliates become aware of a Company Opportunity that is part of an Ancillary Transaction, the Member or Affiliate shall follow the procedures set forth in this Section 14.5(c) in lieu of those set forth in Section 14.5(b). An “Ancillary Transaction” is a transaction in which a Member or its Affiliate proposes, in the same or in a series of related transactions, to purchase or engage in both (a) a Company Opportunity that would be subject to Section 14.5(b), and (b) businesses or operations that, by themselves, would not constitute a Company Opportunity subject to Section 14.5(b) (“Other Business”); provided, however, that a transaction is not an Ancillary Transaction if the revenues for the Company Opportunity for the preceding calendar year are more than 25% of the combined revenues of the Company Opportunity and Other Business for such period.  With respect to any Company Opportunity that is included in an Ancillary Transaction, the Member or its affiliate pursuing such Company Opportunity may consummate the Ancillary Transaction without violating this Section 14.5 provided that the acquiring Member or Affiliate within six months after the Ancillary Transaction consummates a sale of the Company Opportunity to the Company with the express written consent of the Member Group of which it is not a member, which may be withheld in such other Member Group’s sole discretion, for a purchase price equal to (A) the percentage of the EBITDA of the Company Opportunity for the preceding calendar year compared to the combined EBITDA of the Company Opportunity and Other Business for such period, multiplied by (B) the total purchase price for the Ancillary Transaction; provided that, if the other Member Group elects not to consummate the sale of the Company Opportunity to the Company, the acquiring Member shall be free to keep and pursue the Company Opportunity.

             (a)              Each Member recognizes and acknowledges that it may receive certain confidential and proprietary information and trade secrets of the Company and its Affiliates, including but not limited to confidential information of regarding identifiable, specific and discrete business opportunities being pursued by the Company or its Affiliates (the “Confidential Information”).  Each Member (on behalf of itself and, to the extent that such Member would be responsible for the acts of the following persons under principles of agency law, its directors, officers, shareholders, managers, partners, employees, agents and members) agrees that it will not, during or after the term of this Agreement, whether through an Affiliate or otherwise, take commercial or proprietary advantage of or profit from any Confidential Information or disclose Confidential Information to any third party for any reason or purpose whatsoever, except (i) to authorized representatives and employees of the Company or its Affiliates and as otherwise may be proper in the course of performing such Member’s obligations, or enforcing such Member’s rights, under this Agreement; (ii) as part of such Member’s normal reporting or review procedure, or in connection with such Member’s or its Affiliates’ normal marketing, informational or reporting activities, or to such Member’s (or any of its Affiliates’) auditors, attorneys or other agents; (iii) to any bona fide prospective purchaser of the equity or assets of such Member or its Affiliates or the Shares held by such Member, or prospective merger partner of such Member or its affiliates, provided that such purchaser or merger partner agrees to be bound by the provisions of this Section 14.6; or (iv) as is required to be disclosed by order of a court of competent jurisdiction, administrative body or governmental body, or by subpoena, summons or legal process, or by law, rule or regulation, provided that the Member required to make such disclosure shall provide to the Board prompt notice of any such disclosure.  For purposes of this Section 14.6, “Confidential Information” shall not include any information of which such Member (or its affiliates) learns from sources other than the Company, whether prior to or after such information is actually disclosed by the Company.

          (b)             During the term of and for a period of 24 months after the termination of this Agreement, neither Levy nor USC nor any of their respective affiliates will, engage, directly or indirectly, in the Business in the State of Michigan except through its ownership of the Company or after compliance with Section 14.5 above.

          (c)             During the term of and for a period of 24 months after the termination of this Agreement, (i) neither Member nor any of its Affiliates shall directly solicit or induce any officer, director or other employee (each a “Restricted Person”) of the Company, the other Member or any of their Affiliates to leave the employ of the Company, the other Member or such Affiliate; and (ii) the Company shall not directly solicit or induce any Restricted Person of either Member or their Affiliates to leave the employ of such Member or affiliate without the prior written consent of such Member or Affiliate.  The foregoing covenants against solicitation of employees shall not apply to any of a party’s employees who, without any solicitation or recruitment by the other party, contacts the other party regarding possible employment, including without limitation, in response to any general advertisement.

          (d)             Each party acknowledges that its obligations under this Section 14.6 are of a special, unique and extraordinary character, that they are reasonably related to the legitimate business interests of the Members, Company and/or their respective Affiliates, and that a failure to perform any such obligation or a violation of such obligations under this Section 14.6 would cause irreparable harm to the Members, Company and/or their respective Affiliates and the Business, the amount of which may not be readily ascertainable and for which adequate compensation could not be fashioned.  Accordingly, each party agree that each other party will have the right, without the need to prove irreparable injury or to post bond, to obtain an immediate injunction against any breach or threatened breach of this Section 14.6, as well as the right to pursue any and all other rights and remedies available at law or in equity.
