                  4.2.2.2.  Any Loss not allocated to reduce Positive Capital

                  Company's other items of income and gain for the taxable year.
                  It is the intent of the parties hereto that any allocation
                  pursuant to this Section 4.3.2 shall constitute a "minimum
                  gain chargeback" under Regulation Section 1.704-2(f).

         4.3.3.   Contributed Property and Book-ups.
                  In accordance with Code Section 704(c) and the IRS Regulations
                  under 1.704 - 3(c), as well as Regulation Section
                  1.704-1(b)(2)(iv)(d)(3), income, gain, loss, and deduction
                  with respect to any property contributed (or deemed
                  contributed) to the Company shall, solely for tax purposes, be
                  allocated among the Members so as to take account of any
                  variation between the adjusted basis of the property to the
                  Company for federal income tax purposes and its fair market
                  value at the date of contribution (or deemed contribution). If
                  the adjusted book value of any Company asset is adjusted as
                  provided herein, subsequent allocations of income, gain, loss,
                  and deduction with respect to the asset shall take account of
                  any variation between the adjusted basis of the asset for
                  federal income tax purposes and its adjusted book value in the
                  manner required under Code Section 704(c) and the IRS
                  Regulations thereunder.

         4.3.4.   Code Section 754 Adjustment.
                  To the extent an adjustment to the tax basis of any Company
                  asset pursuant to Code Section 734(b) or Code Section 743(b)
                  is required, pursuant to Regulation Section 1.704-1
                  (b)(2)(iv)(m), to be taken into account in determining Capital
                  Accounts, the amount of the adjustment to the 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 basis), and the gain or loss shall be specially
                  allocated to the Members in a manner consistent with the
                  manner in which their Capital Accounts are required to be
                  adjusted pursuant to that Section of the IRS Regulations.

         4.3.5.   Nonrecourse Deductions.
                  Nonrecourse Deductions for a taxable year or other period
                  shall be specially allocated among the Members in proportion
                  to their Percentages.

         4.3.6.   Member Loan Nonrecourse Deductions.
                  Any Member Loan Nonrecourse Deduction for any taxable year or
                  other period shall be specially allocated to the Member who
                  bears the risk of loss with respect to the loan to which the
                  Member Loan Nonrecourse Deduction is attributable in
                  accordance with Regulation Section 1.704-2(b).

         4.3.7.   Guaranteed Payments.
                  To the extent any compensation paid to any Member by the
                  Company, including any fees payable to any Member pursuant to
                  Section 5.3 hereof, is determined by the Internal Revenue
                  Service not to be a guaranteed payment under Code Section
                  707(c) or is not paid to the Member other than in the Person's
                  capacity as a Member within the meaning of Code Section
                  707(a), the Member shall be specially allocated gross income
                  of the Company in an amount equal to the amount of that
                  compensation, and the Member's Capital Account shall be
                  adjusted to reflect the payment of that compensation.

         4.3.8.   Unrealized Receivables.
                  If a Member's Interest is reduced (provided the reduction does
                  not result in a complete termination of the Member's
                  Interest), the Member's share of the Company's "unrealized
                  receivables" and "substantially appreciated inventory" (within
                  the meaning of Code Section 751) shall not be reduced, so
                  that, notwithstanding any other provision of these Regulations
                  to the contrary, that portion of the Profit otherwise
                  allocable upon a liquidation or dissolution of the Company
                  pursuant to Section 4.4 hereof that is taxable as ordinary
                  income (recaptured) for federal income tax purposes shall, to
                  the extent possible without increasing the total gain to the
                  Company or to any Member, be specially allocated among the
                  Members in proportion to the deductions (or basis reductions
                  treated as deductions) giving rise to such recapture.

         4.3.9.   Withholding.
                  All amounts required to be withheld pursuant to Code Section
                  1446 or any other provision of federal, state, or local tax
                  law shall be treated as amounts actually distributed to the
                  affected Members for all purposes under these Regulations.

4.4.     Liquidation and Dissolution.

         4.4.1.   If the Company is liquidated, the assets of the Company shall
                  be distributed to the Members in accordance with the balances
                  in their respective Capital Accounts, after taking into
                  account the allocations of Profit or Loss pursuant to Sections
                  4.1 or 4.2, if any, and distributions, if any, of cash or
                  property, if any, pursuant to Sections 4.1. and 4.2.3.

         4.4.2.   No Member shall be obligated to restore a Negative Capital
                  Account.

4.5.     General.

         4.5.1.   Except as otherwise provided in these Regulations, and except
                  for Member Tax Distributions which shall be made each year
                  that the Company does not have a Loss, the timing and amount
                  of all distributions shall be determined by the Members.

         4.5.2.   If any assets of the Company are distributed in kind to the
                  Members, those assets shall be valued on the basis of their
                  fair market value, and any Member entitled to any interest in
                  those assets shall receive that interest as a tenant-in-common
                  with all other Members so entitled. Unless the Members
                  otherwise agree, the fair market value of the assets shall be
                  determined by an independent appraiser who shall be selected
                  by the Manager. The Profit or Loss for each unsold asset shall
                  be determined as if the asset had been sold at its fair market
                  value, and the Profit or Loss shall be allocated as provided
                  in Section 4.2 and shall be properly credited or charged to
                  the Capital Accounts of the Members prior to the distribution
                  of the assets in liquidation pursuant to Section 4.4.

         4.5.3.   All Profit and Loss shall be allocated and all distributions
                  shall be made to the Persons shown on the records of the
                  Company to have been Members as of the last day of the taxable
                  year for which the allocation or distribution is to be made.
                  Notwithstanding the foregoing, unless the Company's taxable
                  year is separated into segments, if there is a Transfer or an
                  Involuntary Withdrawal during the taxable year, the Profit and
                  Loss shall be allocated between the original Member and the
                  successor on the basis of the number of days each was a Member
                  during the taxable year; provided, however, the Company's
                  taxable year shall be segregated into two or more segments in
                  order to account for Profit, Loss or proceeds attributable to
                  a Capital Transaction or to any other extraordinary
                  non-recurring items of the Company.

         4.5.4.   The Manager is hereby authorized, upon the advice of the
                  Company's tax counsel, to amend this Section IV to comply with
                  the Code and the IRS Regulations promulgated under Code
                  Section 704(b); provided, however, that no amendment shall
                  materially affect distributions to a Member without the
                  Member's prior written consent.

                            virtue of being a Member, and no Member has

                            being a Member.

                  5.1.4.2.  This Section 5.1 supersedes any authority granted to
                            the Members pursuant to the Act. Any Member who

                  Manager or by those Members holding at least thirty percent
                  (30%) of the Percentages then held by Members. Meetings of
                  Members shall be held at the Company's registered office or at
                  any place in Southeastern Michigan designated by the Person
                  calling the meeting. Not less than three (3) nor more than
                  thirty (30) days before each meeting, the Person calling the
                  meeting shall give written notice of the meeting to each
                  Member entitled to vote at the meeting. The notice shall state
                  the time, place, and purpose of the meeting. Notwithstanding
                  the foregoing provisions, each Member who is entitled to
                  notice waives notice if before or after the meeting the Member
                  signs a waiver of the notice that is filed with the records of
                  Members' meetings, or is present at the meeting in person or
                  by proxy. Unless these Regulations provides otherwise, at a
                  meeting of Members, the presence in person or by proxy of
                  Members holding not less than seventy-five percent (75%) of
                  the Percentages then held by Members constitutes a quorum. A
                  Member may vote either in person or by written proxy signed by
                  the Member or by its duly authorized attorney in fact.

         5.2.2.   Wherever these Regulations requires the determination or
                  approval of the Members as set forth in Section 5.1.3, the
                  affirmative vote of Members holding seventy-five percent (75%)
                  or more of the Percentages then held by Members shall be
                  required to approve the matter.

         5.2.3.   In lieu of holding a meeting, the Members may vote by written
                  consent describing the action and signed by each Member
                  entitled to vote on that action. A vote by written consent
                  shall be effective when all Members entitled to vote have
                  signed the consent, unless the consent specifies a different
                  date. A written consent may be executed in counterparts, and
                  shall be filed with the Company's records.

         5.2.4.   In the event that the Company experiences losses in any
                  quarter after June 30, 1999, the Members shall receive a

                  the extent and cause of the losses and a proposed action plan.

         5.2.5.   A meeting of the Members shall occur during the months of
                  March and November, or on other such dates as mutually agreed
                  by the Members. During these meetings, the senior management
                  team of the Company shall make a presentation to the Members
                  summarizing the past and expected future performance of the
                  Company. Such presentations shall not address any business
                  opportunities of the Company to which UTA could be considered
                  a competitor of the Company. The March meeting shall also
                  include a presentation by senior management of the annual
                  report. The November meeting shall also include a presentation
                  by senior management of the Business Plan for the forthcoming
                  year.

         5.3.1.   No Member shall be required to perform services for the
                  Company solely by virtue of being a Member. Unless such
                  services are the subject of a written agreement between the
                  Member and the Company, no Member shall perform services for
                  the Company or be entitled to compensation for services
                  performed for the Company.

5.4.     Duties of Parties.

         5.4.1.   Except as otherwise expressly provided in Section 5.4.2 or
                  Section 7.1.4 or the Act, nothing in these Regulations shall
                  be deemed to restrict in any way the rights of any Member, or
                  of any Affiliate of any Member, to conduct any other business
                  or activity whatsoever, and the Member shall not be
                  accountable to the Company or to any Member with respect to
                  that business or activity, even if the business or activity
                  competes with the Company's business. The organization of the
                  Company shall be without prejudice to their respective rights
                  (or the rights of their respective

                                       20

                  Affiliates) to maintain, expand, or diversify such other
                  interests and activities and to receive and enjoy profits or
                  compensation therefrom. Each Member waives any rights the
                  Member might otherwise have to share or participate in such
                  other interests or activities of any other Member or the
                  Member's Affiliates.

         5.4.2.   Each Member understands and acknowledges that the conduct of
                  the Company's business may involve business dealings and
                  undertakings with Members and their Affiliates. In any of
                  those cases, those dealings and undertakings shall be at arm's
                  length, on commercially reasonable terms, and similar services
                  shall result in comparable compensation.

5.5.     Liability and Indemnification.

         5.5.1.   The Manager shall not be liable, responsible, or accountable,
                  in damages or otherwise, to any Member or to the Company for
                  any omission or any act performed by the Manager within the
                  scope of the authority conferred on the Manager by these
                  Regulations, except for fraud, gross negligence, an
                  intentional breach of these Regulations, or as otherwise
                  required by the Act.

                  permitted by the Act for any liability arising from any actual
                  or alleged omission or any actual or alleged act performed by
                  the Manager within the scope of the authority conferred on the
                  Manager by these Regulations except for fraud, gross
                  negligence or an intentional breach of these Regulations.

5.6.     Power of Attorney.

         5.6.1.   Grant of Power.
                  Each Member constitutes and appoints the Manager as the
                  Member's true and lawful attorney-in-fact
                  ("Attorney-in-Fact"), and in the Member's name, place, and
                  stead, to make, execute, sign, acknowledge, and file:

                  5.6.1.1.  all documents (including amendments to articles of
                            organization) that the Attorney-in-Fact deems
                            necessary or appropriate to reflect any amendment,
                            change, or modification of these Regulations;

                  5.6.1.2.  any and all other certificates or other instruments
                            required to be filed by the Company with the
                            Secretary of State under the laws of the State of
                            Texas or of any other state or jurisdiction
                            necessary in order for the Company to continue to
                            qualify as a limited liability company under the
                            laws of the States of Texas and Michigan or

                                       21

<PAGE>   21

                            any other state where qualification is required;

                  5.6.1.3.  one or more assumed name certificates; and

                  5.6.1.4.  all documents that may be required to dissolve and
                            terminate the Company and to cancel its Articles of
                            Organization if the Company is dissolved in
                            accordance with Section 7.1.

         5.6.2.   Irrevocability.
                  The foregoing power of attorney is irrevocable and is coupled
                  with an interest, and shall not be affected by disability of
                  the principal. It also shall survive the Transfer of an
                  Interest, except that if the transferee is approved for
                  admission as a Member, this power of attorney on behalf of the
                  assigning Member shall survive the delivery of an assignment
                  that terminates the membership interest of the assigning
                  Member for the sole purpose of enabling the Attorney-in-Fact
                  to execute, acknowledge, and file any documents needed to
                  effectuate the substitution. Each Member shall be bound by any
                  representations made by the Attorney-in-Fact acting in good
                  faith pursuant to this power of attorney, and each Member
                  hereby waives any and all defenses that may be available to
                  contest, negate, or disaffirm the action of the
                  Attorney-in-Fact taken in good faith under this power of
                  attorney.

         SECTION VI -- TRANSFER OF INTERESTS AND WITHDRAWALS OF MEMBERS

         6.1.1.   No Person may Transfer all or any portion of or any Interest
                  or rights in the Person's Interest or other Membership Rights
                  unless the following conditions ("Conditions of Transfer") are
                  satisfied:

                  6.1.1.1.  the Transfer will not require registration of any
                            Interest or Membership Rights under any federal or
                            state securities laws;

                  6.1.1.2.  the transferee delivers to the Company a written
                            instrument agreeing to be bound by the terms of
                            Section VI of these Regulations;

                  6.1.1.3.  the Transfer will not result in the termination of
                            the Company pursuant to Code Section 708;

                  6.1.1.4.  the Transfer will not result in the Company being
                            subject to the

                                       22

<PAGE>   22

                            Investment Company Act of 1940, as amended;

                  6.1.1.5   the Transfer, when aggregated with all previous
                            transfers, will not result in the transfer of 80% or
                            more of all Members' Membership Rights or interest
                            within any given calendar year.

                  6.1.1.6.  the transferor and/or the transferee delivers the
                            following information to the Company: (i) the
                            transferee's taxpayer identification number; (ii)
                            the transferee's initial tax basis in the
                            Transferred Interest; and (iii) such instruments of
                            transfer, assignment, and assumption as may be
                            required by the Company in form and substance

         6.1.2.   If the Conditions of Transfer are satisfied, then a Person may
                  Transfer all or any portion of that Person's Interest. The
                  Transfer of an Interest pursuant to this Section 6.1 shall
                  only result, however, in the Transfer of the transferor's
                  right to receive economic distributions, if any, subject to
                  all of the restrictions and limitations that would be
                  applicable to that Interest if it were still held by a Member;
                  and unless admitted as a Member in accordance with Section
                  6.1.5 the transferee of the Interest shall have no right to:
                  (i) become a Member; (ii) exercise any other Membership
                  Rights, including but not limited to the right to participate
                  in any way in the management and affairs of the Company; or
                  (iii) act as an agent of the Company.

         6.1.3.   Each Member and each other holder of an Interest hereby
                  acknowledges the reasonableness of the prohibition contained
                  in this Section 6.1 in view of the purposes of the Company and
                  the relationship of the Members. The attempted Transfer of any
                  Interest or other Membership Rights in violation of the
                  prohibition contained in this Section 6.1 shall be invalid,
                  null and void, and of no force or effect. Any Person to whom
                  any Membership Rights or Interest is attempted to be
                  transferred in violation of this Section shall not be
                  entitled to vote on matters coming before the Members,
                  participate in the management of the Company, act as an agent
                  of the Company, receive distributions from the Company, or
                  have any other rights in or with respect to the Membership
                  Rights or Interest.

         6.1.4.   Transfer Procedure.

                  6.1.4.1.  If a Member or the holder of an Interest (a
                            "Transferor") desires

                                       23

<PAGE>   23

                            to Transfer all or any portion of, or any interest
                            or rights in, the Transferor's Interest (the
                            "Transferor Interest"), the Transferor shall notify
                            the Company of that desire (the "Transfer Notice").
                            The Transfer Notice shall describe the Transferor
                            Interest including the information required pursuant
                            to Sections 6.1.1.2 and 6.1.1.6. The Company shall
                            have the option (the "Purchase Option") to purchase
                            all of the Transferor Interest for a price (the
                            "Purchase Price") equal to the Transferor's
                            Percentage of the Appraised Value (as defined in
                            Section 6.4.1) if the Transfer Notice is dated on or
                            after February 25, 2000. If the Transfer Notice is
                            dated prior to February 25, 2000, the price shall be
                            equal to the amount of the Transferor's Capital
                            Account.

                  6.1.4.2.  The Purchase Option shall be and remain irrevocable
                            for a period (the "Transfer Period") ending at 11:59
                            P.M. local time at the Company's principal office on
                            the thirtieth (30th) day following the date of the
                            determination of the Appraised Value.

                  6.1.4.3.  At any time during the Transfer Period, the Company
                            may elect to exercise the Purchase Option by giving
                            written notice of its election to the Transferor.
                            The Transferor shall not be deemed a Member for the
                            purpose of voting on whether the Company shall elect
                            to exercise the Purchase Option.

                  6.1.4.4.  If the Company elects to exercise the Purchase
                            Option, the Company's notice of its election shall
                            fix a closing date (the "Transfer Closing Date") for
                            the purchase, which shall not be earlier than five
                            (5) days after the date of the notice of election or
                            more than thirty (30) days after the expiration of
                            the Transfer Period.

                  6.1.4.5.  If the Company elects to exercise the Purchase
                            Option, the Purchase Price shall be paid in cash on
                            the Transfer Closing Date.

                  6.1.4.6.  If the Company fails to exercise the Purchase
                            Option, all Members shall use their best efforts to
                            identify a purchaser of the Transferor Interest
                            which is acceptable to the nontransferring Members.
                            One of the criteria to be considered when
                            identifying qualified purchasers is that the
                            products produced by the Company continue to qualify
                            for minority-sourced credit. The target price of
                            such sale shall be the Transferor's Percentage of
                            the Appraised Value, but the actual price may be
                            equal to, greater than, or less than the Purchase
                            Price. Any Member who identifies a purchaser

<PAGE>   24

                            may request that a meeting of Members be called (and
                            if so requested the Company shall hold a meeting of
                            Members) to vote both on whether to approve the
                            purchase by proposed purchaser and admission of the
                            proposed purchaser as a Member upon completion of
                            the proposed purchase. The notice of such meeting
                            shall identify the proposed purchaser and purchase
                            price ("Transferee Purchase Price"). Prior to such
                            meeting the Transferor shall provide to Members the
                            information described in Section 6.1.1.6. The
                            Company shall provide written notice of how each
                            Member voted on each issue and the results of the
                            vote to Transferor within five days after the
                            Members meeting.

                  6.1.4.7.  If the Members approve both the sale and the
                            admission of the proposed purchaser as a Member
                            under Section 6.1.4.6., Transferor shall be free to
                            sell the Transferor Interest to the proposed
                            purchaser at the Transferee Purchase Price within
                            ninety (90) days after Transferor's receipt of the
                            notice of the results of the vote at the Members'
                            meeting and, upon completion of the sale, the
                            purchaser shall become a Member.

                  6.1.4.8.  If the Members do not approve both the purchase and
                            the admission of the proposed purchaser as a Member
                            under Section 6.1.4.6., those Members who do not
                            vote for approval on either issue shall be obligated
                            to prepare a list of approved purchasers to purchase
                            the Transferor Interest. The Members shall use their
                            best efforts to conclude a sale of the Transferor
                            Interest to one of the approved purchasers using the
                            procedures set forth in Sections 6.1.4.6 and 6.1.4.7
                            above. If a sale by SATURN of the Transferor
                            Interest to an approved purchaser is not concluded
                            within one hundred eighty (180) days after the list
                            of approved purchasers is prepared, UTA shall
                            purchase SATURN's Interest. The Purchase Price shall
                            be equal to SATURN's Percentage of the Appraised
                            Value if the Transfer Notice is dated on or after
                            February 25, 2000. If the Transfer Notice is dated
                            prior to February 25, 2000 the price shall be equal
                            to the amount of SATURN's Capital Account.

                  Any attempted Transfer of the Transferor Interest made without
                  strict compliance with the terms, provisions, and conditions
                  of this Section VI (including but not limited to the
                  Conditions of Transfer) and other terms, provisions, and
                  conditions of these Regulations shall be invalid, null and
                  void, and of no force or effect.

         6.1.5.   Admission of Transferee as Member.
                  Except for transfers pursuant to Section 6.1.4.7 and 6.1.4.8,
                  notwithstanding anything contained herein to the contrary, the
                  transferee of all or any portion of or any rights or interest
                  in any Interest or other Membership Rights shall not be
                  entitled to become a Member, or exercise any rights of a
                  Member, unless and until it is admitted as a member; and the
                  transferee shall not be admitted as a Member unless approved
                  by the Members. In the event that a transferee is not approved
                  by the Members after exhaustion of the steps set forth in
                  Section 6.1.4., those Members not voting for approval shall be
                  obligated to purchase the Interest offered for sale at the
                  Appraised Value on a pro rata basis.

6.2.     Voluntary Withdrawal.
         No Member shall have the right to voluntarily withdraw from the
         Company. A Voluntary Withdrawal is a violation of these Regulations,
         and a Member will not be entitled to receive any distribution pursuant
         to Section 5.06 of the Act upon a Voluntary Withdrawal.

6.3.     Involuntary Withdrawal.
         Immediately upon the occurrence of an Involuntary Withdrawal, the
         successor of the Withdrawn Member (if any) shall become an assignee of
         the Member that holds all of its Interest subject to all of the
         restrictions and limitations that would be applicable to that Interest
         if it were still held by the Withdrawn Member, but such successor shall
         not become a Member.

6.4.     Appraised Value.

         6.4.1.   The term "Appraised Value" means the appraised value of the
                  Company on a "going concern" basis as hereinafter provided.
                  Within fifteen (15) days after demand by either one to the
                  other, the Company and the Transferor shall each appoint an
                  appraiser from a list of mutually agreed upon appraisers to
                  determine the value of the Company. If the two appraisers
                  agree upon the value of the Company (or if the two values
                  differ by less than 5%, the difference shall be split), they
                  shall jointly render a single written report stating that
                  value. If the two values determined by the appraisers differs
                  by 5% or more then the two appraisers shall appoint a third
                  appraiser, who shall appraise the Company and determine the
                  value of the Company, and shall render a written report of its
                  opinion thereon. Each party shall pay the fees and other costs
                  of the appraiser appointed by that party, and the fees and
                  other costs of the third appraiser shall be shared equally by
                  both parties.

         6.4.2.   The value contained in the aforesaid joint written report or
                  written report

                                       26

<PAGE>   26
               of the third appraiser, as the case may be, shall be the
               Appraised Value; provided, however, that if the value contained
               in the appraisal report of the third appraiser is more than the
               higher of the first two appraisals, the higher of the first two
               appraisals shall govern; and provided, further, that if the value
               contained in the appraisal report of the third appraiser is less
               than the lower of the first two appraisals, the lower of the
               first two appraisals shall govern.

6.5       Management Incentives.
          Section 6.1.4 shall not apply to the Transfer of an Interest to a
          Person as a result of a management incentive program. The maximum
          Percentage that may be transferred pursuant to any such management
          incentive program shall not exceed four percent (4%) in total.

                    SECTION VII -- DISSOLUTION, LIQUIDATION,
                         AND TERMINATION OF THE COMPANY

7.1.     Events of Dissolution.
         The Company shall be dissolved and its affairs wound up upon the
         happening of any of the following events:

         7.1.1.  When the period fixed for its duration in the Articles has
                 expired; or

         7.1.2.  upon the written agreement of the Members; or

         7.1.3.  upon the written request of any Member holding more than
                 thirty percent (30%) of the Percentages if the products
                 manufactured and / or sold by the Company do not qualify for
                 minority sourced credit by the original equipment
                 manufacturers ultimately purchasing the products. Before
                 such written request is made, the Members shall use their
                 best efforts to requalify such products for minority sourced
                 credit within one hundred eighty (180) days. In the event
                 the disqualification is the result of the existing ownership
                 structure of the Company on the date of signing these
                 Regulations, the Members shall proceed to change the
                 ownership structure of the Company pursuant to the
                 provisions of Section 6.1.4. For purposes of the operation
                 of Section 6.1.4, the date of the Saturn Transfer Notice
                 shall be the date the Company receives notice that its
                 products no longer qualify as minority sourced products.

         7.1.4   upon the written request of any Member holding more than thirty
                 percent (30%) of the Percentages in the event any other
                 Member (the "Competing Member") makes an investment, either
                 directly or indirectly, of greater

                                       27

<PAGE>   27
                  than thirty percent (30%) in any business that supplies
                  Battery Cables, Ground Straps or Trailer Tow Harnesss to
                  Automotive Customers in the Territory.

                  In an attempt to avoid dissolution of the Company pursuant to
                  this Section 7.1.4, the Competing Member shall give written
                  notice to the other Members of its intention to make such an
                  investment on the date of signing of a memorandum of
                  understanding regarding such investment. The other Members
                  shall have the right to call a meeting of the Members to
                  discuss the subject of the competing investment. Following
                  such meeting, any non-Competing Member holding more than
                  thirty percent (30%) of the Percentages shall have the right
                  to proceed with dissolution of the Company or compel the sale
                  of the Competing Member's Interest pursuant to the procedures
                  set forth in Section 6.1.4. For purposes of the operation of
                  Section 6.1.4, the date of the Transfer Notice referenced in
                  Section 6.1.4 shall be the date that the Competing Member
                  signs a memorandum of understanding.

7.2.     Procedure for Winding Up and Distribution.
         If the Company is dissolved, the Manager shall prepare a plan of
         dissolution for approval by the Members, and once the plan is approved,
         shall wind up its affairs. On winding up of the Company, the assets of
         the Company shall be distributed first, to creditors, including Members
         who are creditors, in satisfaction of the liabilities of the Company,
         and then to the Members in accordance with Section 4.4 of these
         Regulations.

                  regarding the state of the business and financial condition of

         8.2.2.   The books and records shall be maintained in accordance with
                  sound accounting practices and shall be available at the
                  Company's principal office, or any other place designated by
                  the Members, for examination by any Member or the Member's

                        SECTION IX -- GENERAL PROVISIONS

9.1.     Assurances.
         Each Member shall execute all such certificates and other documents and
         shall do all such filing, recording, publishing and other acts as the
         Manager deems appropriate to comply with the requirements of law for
         the formation and operation of the Company and to comply with any laws,
         rules, and regulations relating to the acquisition, operation or
         holding of the property of the Company.

9.2.     Notifications.
         Any notice, demand, consent, election, offer, approval, request, or
         other communication (collectively a "notice") required or permitted
         under these Regulations must be in writing and either delivered
         personally or by Federal Express or any other similar overnight
         delivery service, or sent by certified or registered mail, postage
         prepaid, return receipt requested. Any notice to be given hereunder by
         the Company shall be given by the Manager or his designee. A notice
         must be addressed to a Member at the Member's last known address on the
         records of the Company. A notice to the Company must be addressed to
         the Manager at the Company's principal office. A notice delivered
         personally or by an overnight delivery service will be deemed given
         only when acknowledged in writing by the Person or an agent of the
         Person to whom it is delivered. A notice that is sent by mail will be
         deemed given three (3) business days after it is mailed. Any party may
         designate, by notice to all of the others in accordance with this
         Section 9.2, substitute addresses or addressees for notices.
         Thereafter, notices are to be directed to those substitute addresses or
         addressees and the records of the Company, including Exhibit A to these
         Regulations, shall be revised accordingly.

9.3.     Specific Performance.
         The parties recognize that irreparable injury will result from a breach
         of any provision of these Regulations and that money damages will be
         inadequate to fully remedy the injury. Accordingly, in the event of a
         breach or threatened breach of one or more of the provisions of these
         Regulations, any party who may be injured (in addition to any other
         remedies which may be available to that party) shall be entitled to one
         or more preliminary or permanent orders (i) restraining and enjoining
         any act which would constitute a breach or (ii) compelling the
         performance of any obligation which, if not performed, would constitute
         a breach.

9.4.     Complete Agreement.
         These Regulations and the Articles constitute the complete and
         exclusive statement of the agreement among the Members with respect to
         the matters set forth herein. They supersede all prior written and oral
         statements. Except as expressly provided otherwise herein, these
         Regulations may not be amended

                                       31

<PAGE>   31

         without the written consent of all of the Members.

9.5.     Applicable Law.
         All questions concerning the construction, validity, and interpretation
         of these Regulations and the performance of the obligations imposed by
         these Regulations shall be governed by the internal law, not the law of
         conflicts, of the State of Texas.

9.6.     Section Titles.
         The headings herein are inserted as a matter of convenience only, and
         do not define, limit, or describe the scope of these Regulations or the
         intent of the provisions hereof.

9.7.     Binding Provisions.
         These Regulations are binding upon, and inure to the benefit of, the
         parties hereto and their respective heirs, executors, administrators,

9.8.     Jurisdiction and Venue.
         any suit involving any dispute or matter arising under these
         Regulations may only be brought in any United States District Court in
         the State of Michigan or any Michigan State Court having jurisdiction
         over the subject matter of the dispute or matter. All Members hereby
         consent to the exercise of personal jurisdiction by any such court with
         respect to any such proceeding.

9.9.     Construction of Terms.
         Unless the context requires otherwise, common nouns and pronouns shall
         be deemed to refer to the masculine, feminine, neuter, singular, and
         plural, and the words "hereof," "herein," "hereunder," and similar
         terms in these Regulations refer to these Regulations as a whole and
         not to any particular provisions of these Regulations.

9.10.    Separability of Provisions.
         Each provision of these Regulations shall be considered separable; and
         if, for any reason, any provision or provisions herein are determined
         to be invalid and contrary to any existing or future law, such
         invalidity shall not impair the operation of or affect those portions
         of these Regulations which are valid.

9.11.    Estoppel Certificate.
         Each Member shall, within ten (10) days after written request by any

         and (iii) there is no default hereunder by the requesting Person, or if
         there is a default, the nature and extent thereof. If the certificate
         is not received within that ten (10) day period, the Manager shall
         execute and deliver the certificate without qualification on behalf of
         the

                                       32

         5.6; except that if the Manager has actual personal knowledge of any
         qualifications, such qualifications shall be included in the
         certificate.

9.12.    Counterparts.
         These Regulations may be executed in two or more counterparts, each of
         which shall be deemed an original and all of which, when taken
         together, constitute one and the same document. The signature of any
         party to any counterpart shall be deemed a signature to, and may be
         appended to, any other counterpart.

9.13.    Approvals.
