                                      -17-


          (a) Organization. The Company (i) is duly organized, validly existing
     and in good standing under the Laws of the State of Delaware and (ii) has
     full power and authority to enter into and perform its obligations under
     this Operating Agreement.

          (b) Authority; Enforceability. The execution and delivery by the
     Company of this Operating Agreement, and its performance and consummation
     of the transactions contemplated hereby, have been duly authorized by all
     requisite action. This Operating Agreement constitutes a valid and legally
     binding obligation of the Company, enforceable against the Company in
     accordance with its terms, except as the same may be limited by applicable
     bankruptcy, insolvency, moratorium, reorganization, fraudulent transfer or
     other similar Laws of general applicability relating to or affecting
     creditors' rights from time to time in effect and general principles of
     equity, including concepts of materiality, reasonableness, good faith and
     fair dealing, regardless of whether in a proceeding in equity or at law.

          (c) Consents and Approvals. All authorizations, approvals and
     consents, if any, required to be obtained from, and all registrations,
     declarations and filings, if any, required to be made with, all
     Governmental Authorities to permit the Company to issue the Units and to
     execute and deliver, and to perform its obligations under, and to
     consummate the transactions contemplated by, this Operating Agreement have
     been obtained or made, as the case may be, and all such authorizations,
     approvals, consents, registrations, declarations and filings are in full
     force and effect.

          (d) No Violations. Except as otherwise may be required by this
     Operating Agreement, neither the issuance of the Units by the Company, the
     execution or delivery by the Company of this Operating Agreement, the
     performance by the Company of its obligations hereunder, nor the
     consummation by the Company of the transactions contemplated hereby, will
     (i) conflict with, violate or result in a breach of, any of the terms,
     conditions or provisions of any Law applicable to the Company, (ii)
     conflict with, violate or result in a breach of, or constitute a default
     under any of the terms, conditions or provisions of the Certificate, (iii)

the State of Delaware where such qualification is necessary in order to conduct
the business of the Company. At the request of the Board or any Officer, each
Unitholder shall execute, acknowledge, swear to and deliver all certificates and
other instruments conforming with this Operating Agreement that are necessary or
appropriate to qualify, continue and terminate the Company as a foreign limited
liability company in all such jurisdictions in which the Company may or does

     SECTION 2.8 Principal Office; Registered Office. The principal office of
the Company shall be located at 1817 I Avenue, New Castle, Indiana 47362 or at
such other place as the Board may from time to time designate, and all business
and activities of the Company shall be deemed to have occurred at its principal
office. The Company may maintain offices at such other place or places as the
Board deems advisable. Notification of any such change shall be given to all
Unitholders. The registered office of the Company required by the Delaware Act
to be maintained in the State of Delaware shall be the office of the initial
registered agent named in the Certificate or such other office (which need not
be a place of business of the Company) as the Board may designate from time to
time in the manner provided by applicable Law. The registered agent of the
Company for service of process in the State of Delaware shall be the initial
registered agent named in the Certificate or such other Person or Persons as the
Board may designate from time to time in the manner provided by applicable Law.

     SECTION 2.9 Term. The term of the Company commenced upon the filing of the
Certificate in accordance with the Delaware Act and shall continue in existence
until termination and dissolution thereof in accordance with the provisions of
Article XIII.

     SECTION 2.10 No State-Law Partnership. The Unitholders intend that the
Company not be a partnership (including, without limitation, a limited
partnership), and that no Unitholder be a partner of any other Unitholder by
virtue of this Operating Agreement (except for tax purposes as set forth in the
next succeeding sentence of this Section 2.10), and neither this Operating
Agreement nor any other document entered into by the Company or any Unitholder
relating to the subject matter hereof shall be construed to suggest otherwise.
The Unitholders intend that the Company shall be treated as a partnership for
federal and, if applicable, state or local income tax purposes, and that each
Unitholder and the Company shall file all tax returns and shall otherwise take
all tax and financial reporting positions in a manner consistent with such
treatment. Without the vote of the holders of at least 66 2/3% of the
outstanding Class A Units, the Company shall not make an election to be treated
as a corporation for federal income tax purposes pursuant to Treasury Regulation
Section 301.7701-3 (or any successor regulation or provision) and, if
applicable, state and local income tax purposes.

                                   ARTICLE III

                             UNITS; CAPITAL ACCOUNTS

     SECTION 3.1 Unitholders.

     (a) Generally. The name, address, number of Units of each class or series,
Capital Contributions and Capital Account of each Unitholder are listed on
Schedule A. Any reference in this Operating Agreement to Schedule A shall be
deemed to be a reference to Schedule A as amended and in effect from time to
time. The Company and each Unitholder shall file all tax returns, including any
schedules thereto, in a manner consistent with the Capital Accounts. Each Person
listed on Schedule A, upon (i) his, her or its execution of this Operating
Agreement or a counterpart thereto and (ii) receipt (or deemed receipt) by the
Company of such Person's Capital Contribution as set forth on Schedule A, is
hereby admitted to the Company as a Unitholder of the Company. Each Unitholder's
interest in the Company, including such Unitholder's Interest in Profits, Losses
and Distributions of


<PAGE>
                                      -19-


the Company and the right to vote on certain matters as provided in this
Operating Agreement, shall be represented by the Units owned by such Unitholder.
The ownership of Units shall entitle each Unitholder to allocations of Profits,
Losses and Distributions as set forth in Article IV hereof. The Board may in its
discretion issue certificates to the Unitholders representing the Units held by
each Unitholder.

     (b) Representations and Warranties of Unitholders. Each Initial Unitholder,
as of the date hereof by its execution of this Operating Agreement, each other
Unitholder, as of the date of and by its acceptance of any Units, represents and
warrants to the Company and acknowledges that:

          (i) Organization. Such Unitholder is duly organized, validly existing
     and in good standing under the Laws of its jurisdiction of organization and
     has full power and authority to enter into and perform its obligations
     under this Operating Agreement;

          (ii) Authority; Enforceability. The execution and delivery by such
     Unitholder of this Operating Agreement, and its performance and
     consummation of the transactions contemplated hereby, have been duly
     authorized by all requisite action. This Operating Agreement constitutes a
     valid and legally binding obligation of such Unitholder, enforceable
     against such Unitholder in accordance with its terms, except as the same
     may be limited by applicable bankruptcy, insolvency, moratorium,
     reorganization, fraudulent transfer or other similar Laws of general
     applicability relating to or affecting creditors' rights from time to time
     in effect and general principles of equity, including concepts of
     materiality, reasonableness, good faith and fair dealing, regardless of
     whether in a proceeding in equity or at law.

          (iii) Consents and Approvals. All authorizations, approvals and
     consents, if any, required to be obtained from, and all registrations,
     declarations and filings, if any, required to be made with, all
     Governmental Authorities to permit such Unitholder to acquire its Units and
     to execute and deliver, and to perform its obligations under, and to
     consummate the transactions contemplated by, this Operating Agreement have
     been obtained or made, as the case may be, and all such authorizations,
     approvals, consents, registrations, declarations and filings are in full
     force and effect.

          (iv) No Violations. Except as otherwise may be required by this
     Operating Agreement, neither the acquisition by such Unitholder of the
     Units being acquired by it, the execution or delivery by such Unitholder of
     this Operating Agreement, the performance by such Unitholder of its
     obligations hereunder, nor the consummation by such Unitholder of the
     transactions contemplated hereby, will (A) conflict with, violate or result
     in a breach of any of the terms, conditions or provisions of any Law
     applicable to such Unitholder, (B) conflict with, violate or result in a
     breach of, or constitute a default under, any of the terms, conditions or
     provisions of its charter documents, (C) conflict with, violate or result
     in a material breach of, or constitute a material default under, any of the
     terms, conditions or provisions of any material loan agreement, indenture,
     trust deed or other agreement or instrument to which such Unitholder is a
     party or by which it is bound, or (D) result in the creation or imposition
     of any material Lien upon any material property or assets of such
     Unitholder.

                                      -20-


     (c) No Liability of Unitholders.

          (i) Except as otherwise set forth in this Operating Agreement or
     required by applicable Law, no Unitholder shall have any personal liability
     whatsoever in such Unitholder's capacity as a Unitholder, whether to the
     Company, to any of the other Unitholders, to the creditors of the Company
     or to any other third party, for the debts, liabilities, commitments or any
     other obligations of the Company or for any losses of the Company. Each
     Unitholder shall be liable only to make such Unitholder's Capital
     Contribution to the Company, if any, and the other payments provided
     expressly herein.

          (ii) In accordance with the Delaware Act and the Laws of the State of
     Delaware, a Unitholder may, under certain circumstances, be required to
     return amounts previously distributed to such Unitholder. It is the intent
     of the Unitholders that no distribution to any Unitholder pursuant to
     Article IV shall be deemed a return of money or other property paid or
     distributed in violation of the Delaware Act. The payment of any such money
     or distribution of any such property to a Unitholder shall be deemed to be
     a compromise within the meaning of the Delaware Act, and the Unitholder
     receiving any such money or property shall not be required to return to any
     Person any such money or property. However, if any court of competent
     jurisdiction holds that, notwithstanding the provisions of this Operating
     Agreement, any Unitholder is obligated to make any such payment, such
     obligation shall be the obligation of such Unitholder and not of any other
     Unitholder.

     SECTION 3.2 Unitholder Meetings.

     (a) Voting of Unitholders.

          (i) The Class A Unitholders shall be entitled to vote on all matters
     submitted to the Unitholders for a vote, with each Class A Unit entitled to
     one vote. Except as otherwise required by applicable Law, or as provided
     below, the Class B Unitholders shall not be entitled to vote on any matters
     submitted to the Unitholders for a vote, except that the Class B
     Unitholders shall be entitled to vote separately as a class, with each
     Class B Unit entitled to one vote, on each of the following matters:

               (A) any action (including, without limitation, any repeal,
          amendment or modification to the Company's Certificate or this
          Operating Agreement) if such action materially and adversely changes
          any rights, privileges and preferences of the Class B Unitholders;

               (B) any increase in the number of Class B Units; or

               (C) the creation of any new class or series of Units, or
          reclassification of any Units on parity with or having a preference or
          priority over the Class B Units as to voting, dividend, or liquidation
          rights.

          (ii) A quorum shall be present at a meeting of Unitholders if the
     holders of a majority of the outstanding Class A Units are present at the
     meeting in person or by proxy and, if the Class B Unitholders are entitled
     to vote separately as a class on any matter to be decided at such meeting,
     if

                                      -21-


     the holders of a majority of the outstanding Class B Units are present at
     the meeting of the Unitholders in person or by proxy.

          (iii) Except as otherwise provided for in this Operating Agreement
     (including, without limitation, in Section 3.2(j)) or required by
     applicable Law, all matters to be voted on by the Unitholders shall require
     the vote of the holders of a majority of the outstanding Class A Units
     present at a duly held meeting of Unitholders at which a quorum is present,
     and if the Class B Unitholders are entitled to vote separately as a class
     on any matter to be decided at a meeting, all matters to be voted on by the
     holders of Class B Units shall require the vote of the holders of a
     majority of the outstanding Class B Units present at a duly held meeting of
     the Unitholders at which a quorum of the holders of Class B Units is
     present. With respect to any matter, other than a matter for which the vote
     of the holders of a specified portion of all Class A Unitholders is
     expressly required by this Operating Agreement or applicable Law, the vote
     of the holders of a majority of the outstanding Class A Units present at a
     duly held meeting of Unitholders at which a quorum is present or, if the
     Class B Unitholders are entitled to vote separately as a class on any
     matter to be decided at a meeting, the vote of the holders of a majority of
     the outstanding Class B Units present at a duly held meeting of the
     Unitholders at which a quorum of the holders of Class B Units is present
     shall be the act of the Unitholders.

     (b) Place. All meetings of the Unitholders shall be held at the principal
place of business of the Company or at such other place within or without the
State of Delaware as shall be specified or fixed in the notices or waivers of
notice thereof; provided, however, that any or all Unitholders participating in
any such meeting by means of conference telephone or similar communications
equipment pursuant to Section 3.3(d) shall be deemed present at the meeting.

     (c) Adjournment. Notwithstanding the other provisions of the Certificate or
this Operating Agreement, the chairman of the meeting or the holders of 66 2/3%
of the outstanding Class A Units present at the meeting shall have the power to
adjourn such meeting from time to time, without any notice other than
announcement at the meeting of the time and place of the holding of the
adjourned meeting. If such meeting is adjourned by the Class A Unitholders, such
time and place shall be determined by a vote of the holders of 66 2/3% of the
outstanding Class A Units present at such meeting. Upon the resumption of such
adjourned meeting, any business may be transacted that might have been
transacted at the meeting as originally called.

     (d) Annual Meeting. An annual meeting of Unitholders, for the election of
the Managers and for the transaction of such other business as may properly come
before the meeting, shall be held at such place, within or without the State of
Delaware, on such date and at such time as the Board shall fix and set forth in
the notice of the meeting, which date shall be within thirteen (13) months
subsequent to the date of formation of the Company, in the case of the first
annual meeting of Unitholders, or the last annual meeting of Unitholders, in all
other cases.

     (e) Special Meetings. Special meetings of the Unitholders for any proper
purpose or purposes may be called at any time by the Board or the holders of 33
1/3% of the outstanding Class A Units or, if any matter arises as to which the
holders of the Class B Units are entitled to vote, the holders of 33 1/3% of the
outstanding Class B Units. If not otherwise stated in or fixed in accordance

<PAGE>
                                      -22-


with the remaining provisions hereof, the record date for determining Class A
Unitholders or Class B Unitholders, as the case may be, entitled to call a
special meeting is the date any Class A Unitholder or Class B Unitholder, as the
case may be, first signs the notice of that meeting. Only business within the
purpose or purposes described in the notice (or waiver thereof) required by this
Operating Agreement may be conducted at a special meeting of Unitholders.

     (f) Notice. A written or printed notice stating the place, day and hour of
the meeting and, in the case of a special meeting, the purpose or purposes for
which the meeting is called, shall be delivered not less than three (3) Business
Days or more than thirty (30) days before the date of the meeting, either
personally, by mail or by facsimile, by or at the direction of the Board or the
Class A Unitholders or Class B Unitholders, as the case may be, calling the
meeting to each Unitholder. If mailed, any such notice shall be deemed to be
delivered when deposited in the United States mail, addressed to each Unitholder
at its address provided for in the Company's books and records, or to such other
address or to the attention of such other Person as the recipient party has
specified by prior written notice to the sending party. Any Unitholder may waive
any such notice at any time in writing.

     (g) Record Date. The date on which notice of a meeting of Unitholders is
mailed or the date on which the resolution of the Board declaring a distribution
is adopted, as the case may be, shall be the record date for the determination
of the Unitholders entitled to notice of or to vote at such meeting (including
any adjournment thereof) or the Unitholders entitled to receive such
distribution.

     (h) Proxies. A Unitholder may vote either in person or by proxy executed in
writing by such Unitholder. A telegram, telex, cablegram, electronic delivery or
similar transmission by such Unitholder, or a photographic, photostatic,
facsimile or similar reproduction of a writing executed by such Unitholder,
shall be treated as an execution in writing for purposes of this Section 3.2(h).
Proxies for use at any meeting of Unitholders or in connection with the taking
of any action by written consent pursuant to Section 3.3 shall be filed with the
secretary of the Company, before or at the time of the meeting or execution of
the written consent, as the case may be. All proxies shall be received and taken
charge of and all ballots shall be received and canvassed by the secretary of
the Company, who shall decide all questions concerning the qualification of
voters, the validity of the proxies and the acceptance or rejection of votes,
unless an inspector or inspectors shall have been appointed by the chairman of
the meeting, in which event such inspector or inspectors shall decide all such
questions. No proxy shall be valid after eleven (11) months from the date of its
execution unless otherwise provided in the proxy. A proxy shall be revocable
unless the proxy form conspicuously states that the proxy is irrevocable and the
proxy is coupled with an interest. Should a proxy designate two or more Persons
to act as proxies, unless that instrument shall provide to the contrary, a
majority of such Persons present at any meeting at which their powers thereunder
are to be exercised shall have and may exercise all the powers of voting or
giving consents thereby conferred, or if only one be present, then such powers
may be exercised by that one; provided that if an even number attend and a
majority do not agree on any particular issue, the Company shall not be required
to recognize such proxy with respect to such issue if such proxy does not
specify how the Units that are the subject of such proxy are to be voted with
respect to such issue.

     (i) Conduct of Unitholder Meetings. All meetings of the Unitholders shall
be presided over by the chairman of the meeting, who shall be one of the

     (a) Each Unitholder's Capital Account will be credited with:

          (i) any contributions of cash made by such Unitholder to the capital

                                   ARTICLE IV

                   DISTRIBUTIONS; REDEMPTIONS AND ALLOCATIONS

     SECTION 4.1 Distributions.

     (a) Distributions Generally. Subject to compliance with the provisions of
this Operating Agreement (including, without limitation, Sections 3.2(j) and
5.3(g)) and Section 18-607 of the Delaware Act, except as otherwise set forth in
this Section 4.1, the Board may cause the Company to make Distributions at any
time or from time to time. All Distributions shall be made only in the following
order and priority:

          (i) FIRST, to the Class B Unitholders, up to an amount equal to the
     Class B Unreturned Capital as of the time of such Distribution, allocated
     pro rata among the Class B Unitholders based on the respective number of
     Class B Units owned by each Class B Unitholder, and no Distribution or any
     portion thereof may be made pursuant to Section 4.1(a)(ii) until the entire
     amount of Class B Unreturned Capital as of the time of such Distribution
     has been paid in full.

          (ii) THEREAFTER, to the Class A Unitholders, all remaining amounts,
     allocated pro rata among the Class A Unitholders based on the respective
     balances of the Capital Account of each Class A Unitholder.

     (b) Tax Distributions.

          (i) So long as the Company is treated as a partnership for federal,
     state or local income tax purposes the Company shall distribute to each
     Unitholder after the end of each Taxable Year (but no later than the date
     the Company files its federal income tax return), to the extent that funds
     are legally available therefor, an amount of cash which in the good faith
     judgment of the Board equals the excess, if any, of (A) the product of (x)
     the amount of taxable income allocable to such Unitholder in respect of the
     period beginning on the first day of such Taxable Year and ending at the
     close of such Taxable Year, multiplied by (y) the combined maximum federal,
     state and local income tax rate to be applied with respect to such taxable
     income (calculated by using the highest maximum combined marginal federal,
     state and local income tax rates to which such Unitholder may be subject
     and taking into account the deductibility of state and local income tax for
     federal income tax purposes) for such


<PAGE>
                                      -27-


     Taxable Year (making an appropriate adjustment for any rate changes that
     take place during such Taxable Year) over (B) the sum of (x) all prior Tax
     Distributions made to such Unitholder during such Taxable Year and (y) all
     Distributions made to such Unitholder prior to the close of such Taxable
     Year pursuant to Section 4.1(a)(ii).

          (ii) So long as the Company is treated as a partnership for federal,
     state or local income tax purposes, to the extent funds are legally
     available therefor, the Company shall distribute to each Unitholder:

               (A) after the end of the first quarter of each Taxable Year of
          the Company, 25% of the amount the Company estimates that it will be
          required to distribute to each Unitholder in respect of such Taxable
          Year pursuant to Section 4.1(b)(i);

               (B) after the end of the second quarter of each Taxable Year of
          the Company, (x) 50% of the amount the Company estimates that it will
          be required to distribute to each Unitholder in respect of such
          Taxable Year pursuant to Section 4.1(b)(i) (determined without regard
          to the amount of any Tax Distributions made pursuant to this Section
          4.1(b)(ii)), less (y) the amount distributed to such Unitholder
          pursuant to Section 4.1(b)(ii)(A) for the first quarter of such
          Taxable Year; and

               (C) after the end of the third quarter of each Taxable Year of
          the Company, (x) 75% of the amount the Company estimates that it will
          be required to distribute to each Unitholder in respect of such
          Taxable Year pursuant to Section 4.1(b)(i) (determined without regard
          to the amount of any Tax Distributions made pursuant to this Section
          4.1(b)(ii)), less (y) the sum of the amounts distributed to such
          Unitholder pursuant to Section 4.1(b)(ii)(A) and (B) for the first and
          second quarters of such Taxable Year.

     If the total amount of the Distributions made by the Company to any
Unitholder pursuant to this Section 4.1(b)(ii) with respect to the first three
quarters of any Taxable Year exceeds the amount that the Company is required to
distribute to such Unitholder pursuant to Section 4.1(b)(i) for such Taxable
Year (such excess, the "Excess Tax Distributions"), then each Unitholder shall
return to the Company the Excess Tax Distributions for such Taxable Year within
thirty (30) days of receipt of notice from the Company that the return of such
Excess Tax Distributions is required.

          (iii) If the Company does not have funds legally available to
     distribute on a timely basis the full Tax Distributions required pursuant
     to this Section 4.1(b), then: (A) Tax Distributions shall be made to the
     Unitholders in proportion to the Tax Distributions they would have received
     had the full amount of funds been legally available; and (B) the unpaid
     amount shall (x) carry forward and be paid by the Company as soon as the
     Company has funds legally available and (y) bear interest at a rate of 8%
     from the date the unpaid amount would have been paid had the full amount of
     funds been legally available until the date such unpaid amount is paid.

     (c) Persons Receiving Distributions. Each Distribution shall be made to the
Persons shown on the Company's books and records as Unitholders as of the date
of such Distribution; pro-


<PAGE>
                                      -28-


vided, however, that any transferor and Permitted Transferee of Units may
mutually agree as to which of them should receive payment of any Distribution
under this Section 4.1.

         SECTION 4.2 Allocations. The following allocations shall be made for
each Taxable Year of after all allocations pursuant to Section 4.3 for such
Taxable Year:

     (a) Net Profit for a Taxable Year shall be allocated:

          (i) First, to the Class A Unitholders pro rata based on the respective
     number of Class A Units owned by each Class A Unitholder, to the extent of
     any excess of Net Losses allocated to the Class A Unitholders under Section
     4.2(b)(iv) for prior periods over Net Profits allocated to the Class A
     Unitholders under this Section 4.2(a)(i) for prior periods;

          (ii) Second, to the Class B Unitholders pro rata based on the
     respective number of Class B Units owned by each Class B Unitholder, to the
     extent of any excess of Net Losses allocated to the Class B Unitholders
     under Section 4.2(b)(iii) for prior periods over Net Profits allocated to
     the Class B Unitholders under this Section 4.2(a)(ii) for prior periods;

          (iii) Third, to the Class A Unitholders pro rata based on the
     respective number of Class A Units owned by each Class A Unitholder, to the
     extent of any excess of Net Losses allocated to the Class A Unitholders
     under Section 4.2(b)(ii) for prior periods over Net Profits allocated to
     the Class A Unitholders under this Section 4.2(a)(iii) for prior periods;

          (iv) Fourth, to DaimlerChrysler, to the extent of any excess of Net
     Losses allocated to DaimlerChrysler under Section 4.2(b)(i) for prior
     periods over Net Profits allocated to DaimlerChrysler under this Section
     4.2(a)(iv) for prior periods; and

          (v) Fifth, to the Class A Unitholders pro rata based on the respective
     number of Class A Units owned by each Class A Unitholder.

          (b) Net Loss for a Taxable Year shall be allocated:

          (i) First, to DaimlerChrysler, to the extent of any excess of (A) the
     sum of DaimlerChrysler's Additional Contributions under Article XVI and any
     Net Profits allocated to DaimlerChrysler under Section 4.2(a)(iv), over (B)
     Net Losses allocated to DaimlerChrysler under this Section 4.2(b)(i) for
     prior periods;

          (ii) Second, to the Class A Unitholders pro rata based on, and to the
     extent of, the positive balances of their Capital Accounts, excluding any
     Class B Unreturned Capital;

          (iii) Third, to the Class B Unitholders, to the extent of the
     remaining balance in its Capital Account; and


<PAGE>
                                      -29-


          (iv) Fourth, the Class A Unitholders pro rata based on the respective
     number of Class A Units owned by each Class A Unitholder.

     SECTION 4.3 Special Allocations. The following special allocations shall,
except as otherwise provided, be made in the following order:

          (a) Notwithstanding any other provision of this Article IV, if there
     is a net decrease in Company Minimum Gain or in any Unitholder Minimum Gain
     during any Taxable Year of the Company, prior to any other allocation
     pursuant hereto, such Unitholder shall be specially allocated items of
     Company Profit for such year (and, if necessary, subsequent years) in an
     amount and manner required by Treasury Regulation Sections 1.704-2(f) or
     1.704-2(i)(4), as appropriate. The items to be so allocated shall be
     determined in accordance with Treasury Regulation Section 1.704-2 in
     compliance with such Treasury Regulations.

          (b) Any Unitholder who unexpectedly receives an adjustment, allocation
     or distribution described in Treasury Regulation Section
     1.704-1(b)(2)(ii)(d)(4), (5) or (6) which causes or increases a negative
     balance in his or its Capital Account shall be allocated items of Profit
     sufficient to eliminate the negative balance in its Capital Account, as
     quickly as possible, to the extent and in the manner required by Treasury
     Regulation Section 1.704-1(b)(2)(ii)(d).

          (c) Nonrecourse Deductions for any Taxable Year of the Company or
     other period shall be allocated (as nearly as possible) under Treasury
     Regulation Section 1.704-2 to the Class A Unitholders pro rata in
     proportion to their respective ownership of Class A Units.

          (d) Any Unitholder Nonrecourse Deductions for any Taxable Year of the
     Company or other period shall be allocated to the Unitholder that made or
     guaranteed or is otherwise liable with respect to the loan to which such
     Unitholder Nonrecourse Deductions are attributable in accordance with
     principles under Treasury Regulation Section 1.704-2(i).

          (e) No allocation of Loss shall be made to any Unitholder if, as a
     result of such allocation, such Unitholder would have an Adjusted Capital
     Account Deficit. Any such disallowed allocation shall be made to the
     Unitholders entitled to receive such allocation under Treasury Regulation
     Section 1.704-1 in proportion to their respective ownership of Class A
     Units first (to the extent allowable under Treasury Regulation Section
     1.704-1) and thereafter in proportion to their respective ownership of
     Class B Units.

          (f) The allocations set forth in Sections 4.3(a) through (e) (the
     "Regulatory Allocations") are intended to comply with certain requirements
     of Sections 1.704-1(b) and 1.704-2 of the Treasury Regulations. The
     Regulatory Allocations may not be consistent with the manner in which the
     Unitholders intend to allocate Profit and Loss of the Company or make
     Distributions. Accordingly, notwithstanding the other provisions of this
     Article IV, but subject to the Regulatory Allocations, income, gain,
     deduction and loss shall be reallocated among the Unitholders so as to
     eliminate the effect of the Regulatory Allocations and thereby cause the
     respective Capital Accounts of the Unitholders to be in the amounts (or as
     close


<PAGE>
                                      -30-


     thereto as possible) they would have been if Profit and Loss (and such
     other items of income, gain, deduction and loss) had been allocated without
     reference to the Regulatory Allocations. In general, the Unitholders
     anticipate that this will be accomplished by specially allocating other
     Profit and Loss (and such other items of income, gain, deduction and loss)
     among the Unitholders so that the net amount of the Regulatory Allocations
     and such special allocations to each such Unitholder is zero.

     SECTION 4.4 Tax Allocations.

     (a) Except as otherwise provided in this Operating Agreement, all items of
Company income, gain, loss, deduction and any other allocation not otherwise
provided for shall be divided among the Unitholders in the same proportions as
they share the corresponding item of Profit and Loss, as the case may be, for
the Taxable Year.

     (b) Items of Company taxable income, gain, loss, and deduction with respect
to any property contributed to the capital of the Company shall be allocated
among the Unitholders in accordance with Code Section 704(c) so as to take
account of any variation between the adjusted basis of such property to the
Company for federal income tax purposes and its Book Value under the traditional
method as set forth in Treasury Regulation Section 1.704-3(b).

     (c) If the Book Value of any Company asset is adjusted pursuant to the
requirements of Treasury Regulation Section 1.704-1(b)(2)(iv)(e) or (f)
subsequent allocations of items of taxable income, gain, loss, and deduction
with respect to such asset shall take account of any variation between the
adjusted basis of such asset for federal income tax purposes and its Book Value
in the same manner as under Code Section 704(c) under the traditional method as
set forth in Treasury Regulation Section 1.704-3(b).

     (d) Allocations of tax credits, tax credit recapture, and any items related
thereto shall be allocated to the Unitholders according to their interests in
such items as determined by the Board taking into account the principles of
Treasury Regulation Section 1.704-1(b)(4)(ii).

     (e) Allocations pursuant to this Section 4.4 are solely for purposes of
federal, state and local taxes and shall not affect, or in any way be taken into
account in computing, any Unitholder's Capital Account or Interest in Profits,
Losses, Distributions, or other Company items pursuant to any provision of this
Operating Agreement.

     SECTION 4.5 Adjustment of Book Value of Assets. The Board shall adjust the
Book Value of each of the assets of the Company to equal such asset's gross Fair
Market Value in a manner consistent with Section 14.2 immediately prior to the
occurrence of each of the following events (the date of each such event, a
"Valuation Date"): (i) the acquisition of Units by any Unitholder in connection
with a contribution of money or other property (other than a de minimis amount);
(ii) the liquidation of the Company within the meaning of Treasury Regulation
Section 1.704-1(b)(2)(ii)(g) (other than a deemed liquidation described in
Treasury Regulation Section 1.704-1(b)(2)(iv)(l)) or (iii) any Distribution of
money or other property (other than a de minimis amount) by the Company to a
withdrawing or continuing Unitholder as consideration for an Interest in the
Company.

     SECTION 4.6 Indemnification for Payments on Behalf of a Unitholder. If the
Company is required by applicable Law to make any payment that is specifically
attributable to a Unitholder or a Unitholder's status as such (including federal
withholding taxes, state personal property taxes and state unincorporated
business taxes), the Company shall treat such payment as a Distribution to such
Unitholder for all purposes (including, for the avoidance of doubt, a Tax
Distribution made pursuant to Section 4.1(b)). If there are insufficient amounts
otherwise distributable to such Unitholder to be fully offset by such payment,
then such Unitholder shall indemnify the Company in full for the entire amount
not so offset (including interest, penalties and related expenses). The Company
may pursue and enforce all rights and remedies it may have against each
Unitholder under this Section 4.6, including instituting a lawsuit to collect
such indemnification with interest calculated at a rate equal to 8% per annum,
compounded as of the last day of each year (but not in excess of the highest
rate per annum permitted by applicable Law).

                                    ARTICLE V

                           BOARD OF MANAGERS; OFFICERS

     SECTION 5.1 Management by the Board of Managers.

     (a) Unitholders Elect Board. The Unitholders shall not manage and control
the business and affairs of the Company, except for situations in which the
approval of the Unitholders is required by this Operating Agreement (including,
without limitation, Section 3.2(j)) or non-waivable provisions of applicable
Law. The Board shall be elected by the Unitholders pursuant to Section 5.2(a).

     and agrees that no Unitholder shall, as a result of being a Unitholder (as
     such), be bound to devote all of its business time to the affairs of the
     Company, and that it and its Affiliates do and will continue to engage for
     their own account and for the accounts of others in other business
     ventures.

     SECTION 5.2 Composition and Election of the Board of Managers.

     (a) Number and Election. The number of Managers on the Board shall be nine
(9). The Managers shall be designated as follows:

          (i) five (5) Managers will be designated by DaimlerChrysler; and

          (ii) four (4) Managers will be designated by Metaldyne.

                                      -33-


     The initial Managers designated by DaimlerChrysler shall be [ ]. The
initial Managers designated by Metaldyne shall be [ ]. Each Class A Unitholder
agrees to vote all of its Class A Units at any annual or special meeting of
Unitholders called for the purpose of electing Managers to the Board, on in any
written consent executed in lieu of such a meeting of Unitholders, in favor of
the individuals designated by DaimlerChrysler and Metaldyne in accordance with
this Section 5.2 (including any replacements designated pursuant to Section
5.2(d)), and to take any and all other actions as may be necessary or desirable
to ensure that the Board is comprised in accordance with the foregoing at all
times.

     (b) Term. Members of the Board shall serve until their resignation, death
or removal or the election of their successors in accordance with the terms
hereof. Members of the Board need not be Unitholders and need not be residents
of the State of Delaware. A member of the Board may resign as such by delivering
his, her or its written resignation to the Company at the Company's principal
office addressed to the Board. Such resignation shall be effective upon receipt
unless it is specified to be effective at some other time or upon the happening
of some other event.

     (c) Removal and Resignation. Any Manager may be removed at any time, with
or without cause, by the Person or Persons entitled to designate such Manager
pursuant to Section 5.2(a). Any Manager or the entire Board may be removed at
any time, for "cause" (as defined below), by the vote of the holders of 66 2/3%
of Class A Units. For the purposes of this Section 5.2(c), "cause" shall mean
the conviction of any felony. Each Class A Unitholder agrees that it will not
vote any of its Class A Units at any annual or special meeting of Unitholders,
or in any written consent executed in lieu of such a meeting of Unitholders, in
favor of the removal of any Manager who shall have been designated pursuant to
Section 5.2(a) unless (i) such removal shall be for cause or (ii) the Person or
Persons entitled to designate such Manager shall have requested or consented to
such removal in writing. Each Class A Unitholder agrees to vote all of its Class
A Units at any annual or special meeting of Unitholders called for the purpose
of removing a Manager from the Board, or in any written consent executed in lieu
of such a meeting of Unitholders, in favor of the removal of any Manager who
shall have been designated pursuant to Section 5.2(a) if the Person or Persons
entitled to designate such Manager shall have requested or consented to such
removal in writing.

     (d) Vacancies. If there shall exist or occur any vacancy on the Board as a
result of the resignation, death or removal, with or without cause, of a
Manager, the Person or Persons entitled under Section 5.2(a) to designate such
Manager whose resignation, death or removal resulted in such vacancy may
designate another individual to fill such vacancy and serve as a Manager on the
Board. The Board shall appoint each Manager so designated to fill such vacancy
and such Manager hold office until his successor is duly elected and qualified
or until his earlier death, resignation or removal as provided herein.

     (e) Reimbursement. The Company shall pay all reimbursable out-of-pocket
costs and expenses incurred by each member of the Board incurred in the course
of their service hereunder, including in connection with attending regular and
special meetings of the Board, any board of managers or board of directors of
any of the Company's Subsidiaries and any committee thereof.

                                      -34-


     (f) Compensation of Managers. Managers shall receive no compensation for
serving in such capacity.

     SECTION 5.3 Board Meetings and Actions by Written Consent.

     (a) Quorum; Voting. A majority of the total number of Managers must be
present (including pursuant to Section 5.3(g)) in order to constitute a quorum
for the transaction of business of the Board. Except as otherwise provided in
this Operating Agreement (including, without limitation, in Section 5.3(g)), the
act of a majority of the Managers present at a duly held meeting of the Board at
which a quorum is present shall be the act of the Board.

     (b) Place; Attendance. Meetings of the Board may be held at such place or
places as shall be determined from time to time by resolution of the Board. All
meetings of the Board shall be presided over by a Chairman who shall be a
Manager designated by DaimlerChrysler from time to time (and not unreasonably
objected to by Metaldyne). At all meetings of the Board, business shall be
transacted in such order as shall from time to time be determined by resolution
of the Board. Attendance of a Manager at a meeting shall constitute a waiver of
notice of such meeting, except where a Manager attends a meeting for the express
purpose of objecting to the transaction of any business on the ground that the
meeting is not lawfully called or convened.

     (c) Special Meetings. Special meetings of the Board may be called by any
Manager on at least 48 hours' notice to each other Manager. Such notice need not
state the purpose or purposes of, or the business to be transacted at, such
meeting, except as may otherwise be required by applicable Law or provided for
in this Operating Agreement. Any Manager may waive any such notice at any time
in writing.

     (d) Time, Place and Notice. Notice of regular meetings of the Board or of
any adjourned regular meeting will be given in writing at least ten (10)
Business Days prior to such meeting, unless otherwise agreed in writing by each
Unitholder. Notices of special meetings of the Board or of any adjourned special
meeting will be faxed to each Manager addressed to him or her at his or her
residence or usual place of business, so as to be received at least two (2)
Business Days before the day on which such meeting is to be held. Such notice
will include the purpose, time and place of such meeting and will set forth in
reasonable detail the matters to be considered at such meeting. However, notice
of any such meeting need not be given to any Manager if such notice is waived by
him or her in writing, whether before or after such meeting is held, or if he or
she is present at such meeting (unless such Manager objects, before any business
is conducted thereat, to the holding of such meeting without due notice), or
with respect to a regular meeting scheduled at a meeting of the Board held at
least twenty (20) calendar days prior to the date of a subsequent meeting.

     (e) Chairman and Vice Chairman. The Board shall designate one of the
Managers to serve as Chairman and a different Manager to serve as Vice Chairman.
The Chairman shall preside at all meetings of the Board. If the Chairman is
absent at any meeting of the Board, the Vice Chairman shall preside over such
Board meeting. If the Chairman and Vice Chairman are absent, the Managers
present shall designate a member to serve as interim chairman for that meeting.


<PAGE>
                                      -35-


     (f) Action by Written Consent or Telephone Conference. Any action permitted
or required by the Delaware Act, the Certificate or this Operating Agreement to
be taken at a meeting of the Board or any committee designated by the Board may
be taken without a meeting if a consent in writing, setting forth the action to
be taken, is signed by all the Managers or members of such committee, as the
case may be. Such consent shall have the same force and effect as a unanimous
vote at a meeting and may be stated as such in any document or instrument filed
with the Secretary of State of Delaware, and the execution of such consent shall
constitute attendance or presence in person at a meeting of the Board or any
such committee, as the case may be. Subject to the requirements of the Delaware
Act, the Certificate or this Operating Agreement for notice of meetings, unless
otherwise restricted by the Certificate, the Managers or members of any
committee designated by the Board may participate in and hold a meeting of the
Board or any committee, as the case may be, by means of a conference telephone
or similar communications equipment by means of which all persons participating
in the meeting can hear each other, and participation in such meeting shall
constitute attendance and presence in person at such meeting, except where a
person participates in the meeting for the express purpose of objecting to the
transaction of any business on the ground that the meeting is not lawfully
called or convened.

     (g) Board Actions Requiring Supermajority Approval. Notwithstanding any
other provision of this Operating Agreement, the vote of at least 66 2/3% of the
total number of Managers shall be required for the Board to approve any of the
actions set forth on Exhibit A (and such vote shall be required for the Company
to take any action in its capacity as holder of voting securities of any of its
Subsidiaries with respect to any substantially similar actions proposed to be
taken by or with respect to such Subsidiary). The Company shall take any and all
actions as may be necessary or desirable to ensure that each Subsidiary of the
Company, before taking any actions substantially similar to those set forth on
Exhibit A, must receive the consent of the Company in its capacity as holder of
voting securities of such Subsidiary.

     (h) Board Approval of Local Qualified Collective Bargaining Agreements.
Notwithstanding any other provision of this Operating Agreement, (i) a majority
of the Managers designated by Metaldyne shall constitute a quorum for purposes
of approving Local Qualified Collective Bargaining Agreements and (ii) with
respect to Local Qualified Collective Bargaining Agreements, the act of a
majority of the Managers designated by Metaldyne present at a duly held meeting
of the Board at which a quorum (as defined in clause (i) above) is present shall
be the act of the Board.

     SECTION 5.4 Committees; Delegation of Authority and Duties.

     (a) Committees. The Board may, from time to time, designate one or more
committees and delegate any of its authority and duties to any such committee;
provided that the Board may not delegate all of its authority and duties to any
such committee. At least one third of the members of each such committee must be
Managers designated by Metaldyne and no more than two thirds of the members of
each such committee must be Managers designated by DaimlerChrysler (other than
any committee constituted (i) for the purpose of assessing or determining any
matter in which Metaldyne or DaimlerChrysler, as the case may be, has any
interest materially adverse to any interest of the Company or any other
Unitholder or (ii) solely of independent Managers in order to comply with or to
be afforded protections under Delaware Law, including the Delaware Act). Subject
to Section 5.3(g),


<PAGE>
                                      -36-


at every meeting of any such committee, including, without limitation, the audit
committee, the presence of a majority of all the members thereof shall
constitute a quorum, and the affirmative vote of a majority of the members
present shall be necessary for the adoption of any resolution.

     (b) Audit Committee. The Board may establish an audit committee to select
the Company's independent accountants and to review the annual audit of the
Company's financial statements conducted by such accountants. Such committee
shall be comprised of three (3) Managers, one (1) of whom shall be a Manager
designated by Metaldyne and two (2) of whom shall be Managers designated by
DaimlerChrysler.

     (c) Delegation to Other Persons. The Board may, from time to time, delegate
to one or more Persons (including any Manager or Officer) such authority and
duties as the Board may deem advisable, including pursuant to a management
agreement or another with, or otherwise to, one or more Persons (including any
Manager). The Board also may assign titles (including chairman, vice chairman,
chief executive officer, president, chief financial officer, vice president,
secretary, assistant secretary, treasurer and assistant treasurer) to any
Manager, Unitholder or other individual and may delegate to such Manager,
Unitholder or other individual certain authority and duties. Any number of
titles may be held by the same Manager, Unitholder or other individual. Subject
to Section 5.3(g), any delegation pursuant to this Section 5.4(c) may be revoked
at any time by the Board, without prejudice, however, to any rights under the
provisions of any management, employment or other agreement pursuant to which
such delegation was made.

     SECTION 5.5 Officers.

     (a) Designation and Appointment. The Board may (but need not), from time to
time, designate and appoint one or more persons as an Officer of the Company. No
Officer need be a resident of the State of Delaware, a Unitholder or a Manager.
Any Officers so designated shall have such authority and perform such duties as
the Board may, from time to time, delegate to them. The Board may assign titles
to particular Officers. Unless the Board otherwise decides, if the title is one
commonly used for officers of a business corporation formed, the assignment of
such title shall constitute the delegation to such Officer of the authority and
duties that are normally associated with that office, subject to (i) any
specific delegation of authority and duties made to such Officer by the Board
pursuant to the third sentence of this Section 5.5(a) or (ii) any delegation of
authority and duties made to one or more Officers pursuant to the terms of
Sections 5.4(c) and 5.5(c). Each Officer shall hold office until such Officer's
successor shall be duly designated and shall qualify or until such Officer's
death or until such Officer shall resign or shall have been removed in the
manner hereinafter provided. Any number of offices may be held by the same
individual. The salaries or other compensation, if any, of the Officers and
agents of the Company shall be fixed from time to time by the Board.

     (b) Resignation. Any Officer (subject to any contract rights available to
the Company, if applicable) may resign as such at any time. Such resignation
shall be made in writing and shall take effect at the time specified therein, or
if no time be specified, at the time of its receipt by the Board. The acceptance
of a resignation shall not be necessary to make it effective, unless expressly
so provided in the resignation. Any Officer may be removed as such, either with
or without cause, by the


<PAGE>
                                      -37-


Board whenever in its judgment the best interests of the Company shall be served
thereby; provided, however, that such removal shall be without prejudice to the
contract rights, if any, of the individual so removed. Designation of an Officer
shall not of itself create contract rights. Any vacancy occurring in any office
of the Company may be filled by the Board.

     (c) Duties of Officers. Subject to Section 6.5, the Officers (including any
person designated by Metaldyne to function as an Officer), in the performance of
their duties as such, shall owe to the Unitholders duties of loyalty and due
care of the type owed by the officers of a corporation to such corporation and
its stockholders under the Laws of the State of Delaware.

                                   ARTICLE VI

                  GENERAL RIGHTS AND OBLIGATIONS OF UNITHOLDERS

     SECTION 6.1 Limitation of Liability. Except as otherwise provided by this
Operating Agreement or applicable Law, the debts, obligations and liabilities of
the Company, whether arising in contract, tort or otherwise, shall be solely the
debts, obligations, and liabilities of the Company, and no Unitholder shall be
obligated personally for any such debt, obligation or liability of the Company
solely by reason of being a Unitholder of the Company; provided, however, that a
Unitholder shall be required to return to the Company any Distribution made to
it in clear and manifest accounting or similar error. The immediately preceding
sentence shall constitute a compromise to which all Unitholders have consented
within the meaning of the Delaware Act. Notwithstanding any other provision of
this Operating Agreement, the failure of the Company to observe any formalities
or requirements relating to the exercise of its powers or management of its
business and affairs under this Operating Agreement or the Delaware Act shall
not be grounds for imposing personal liability on the Unitholders for
liabilities of the Company.

     SECTION 6.2 Lack of Authority. Without derogation to a Unitholder's rights
or obligations under any Related Agreement, no Unitholder in its capacity as
such (other than the members of the Board acting as the Board or an authorized
Officer of the Company acting as such) has the authority or power to act for or
on behalf of the Company in any manner, to do any act that would be (or could be
construed as) binding on the Company or to make any expenditures on behalf of
the Company, and the Unitholders hereby consent to the exercise by the Board of
the powers conferred on it by applicable Law and this Operating Agreement.

     SECTION 6.3 No Right of Partition. No Unitholder shall have the right to
seek or obtain partition by court decree or operation of applicable Law of any
Company property, or the right to own or use particular or individual assets of
the Company.

     SECTION 6.4 Unitholders' Right To Act. For situations which the approval of
any Unitholders or class thereof (rather than the approval of the Board on
behalf of the Unitholders) is required, the Unitholders shall act through
meetings and written consents as described in Section 3.2.

     SECTION 6.5 Conflicts of Interest. A Unitholder, its Affiliates and each of
their respective stockholders, directors, officers, controlling persons,
partners and employees (collectively, the


<PAGE>
                                      -38-


"Unitholder Group") may have business interests and engage in business
activities in addition or similar to those relating to the Company and its
Subsidiaries, except as any such Person may have otherwise agreed with the
Company or another Unitholder in writing. Neither the Company nor any other
Unitholders shall have any rights by virtue of this Operating Agreement , such
Person's status as a member of a Unitholder Group or ownership of Units or
otherwise, in any business ventures of any such Person except as and to the
extent expressly provided in any written agreement among the relevant parties.
Without limiting the generality of the foregoing and to the fullest extent
permitted by Delaware Law (but subject to this Section 6.5), except as otherwise
expressly provided in this Operating Agreement or any other written agreement
between the Company and a Unitholder, if any of the Unitholders, any of their
respective Affiliates (other than the Company) or any of their officers,
directors, agents, stockholders, members or partners acquires knowledge of, or
engages in or exploits, any Corporate Opportunity, the Company shall have no
interest or expectancy in, or in being offered an opportunity to participate in,
such Corporate Opportunity, any such interest or expectancy being hereby
renounced, so that, as a result of such renunciation, such Person (a) shall have
no duty to communicate or present such Corporate Opportunity to the Company, (b)
shall have the right to hold any such Corporate Opportunity for his, her or its
(and/or his, her or its officers', directors', agents', stockholders', members'
or partners') own account or to recommend, sell, assign, or transfer such
Corporate Opportunity to Persons other than the Company, and (c) shall not
breach any fiduciary duty to the Company, in such Person's capacity as a
Unitholder of the Company or otherwise, by reason of the fact that such Person
pursues or acquires such Corporate Opportunity for itself, directs, sells,
assigns, or transfers such Corporate Opportunity to another Person, or does not
communicate information regarding such Corporate Opportunity to the Company.

     SECTION 6.6 Transactions Between the Company and the Unitholders.
Notwithstanding that it may constitute a conflict of interest or Corporate
Opportunity in which the Company has an interest pursuant to Section 6.5, the
Unitholders or their Affiliates may engage in any transaction (including the
purchase, sale, lease or exchange of any property or rendering of any service or
the establishment of any salary, other compensation or other terms of
employment) with the Company (a) to the extent permitted by the Related
Agreements or (b) so long as such transaction is approved by the Board in
advance by the vote of 66 2/3% of the total number of Managers.

     SECTION 6.7 Right of Inspection. From and after the date hereof, the
Company will permit each Unitholder or its representatives, at such Unitholder's
expense, to visit any of the properties of the Company, to examine all its books
of account, records, reports and other papers, to make copies and extracts
therefrom, and to discuss its affairs, finances and accounts with its officers,
directors, key employees and independent accountants or any of them (and by this
provision the Company authorizes said accountants to discuss with said
Unitholder and its representatives the finances and affairs of the Company and
its subsidiaries; provided, however, that the Company shall be provided
reasonable advance notice of such Person's intention to speak with such
accountants and the Company shall be provided a reasonable opportunity to
address the questions or matters proposed to be discussed with the accountants
prior to such Person contacting the accountants directly), all at such
reasonable times and all on reasonable notice as may be reasonably requested by
such Unitholder.

                                   ARTICLE VII

                         EXCULPATION AND INDEMNIFICATION

     SECTION 7.1 Liability. Except as otherwise provided under the Laws of the
State of Delaware or pursuant to this Operating Agreement, the debts,
obligations and liabilities of the Company, whether arising in contract, tort or
otherwise, will be solely the debts, obligations and liabilities of the Company,
and no Manager or Officer will be obligated personally for any such debt,
obligation or liability of the Company.

     SECTION 7.2 Exculpation. Except as otherwise provided by this Operating
Agreement, no Officer or Manager shall be liable to any other Officer, Manager
or the Company or to any Unitholder for any loss, damage or claim suffered by
the Company as a result of actions taken in good faith and reasonably believed
by the Officer or Manger to be in, or not opposed to, the best interests of the
Company, unless such loss is caused by such Person's gross negligence, willful
misconduct, violation of applicable Law or material breach of this Operating
Agreement. The Officers and Managers shall not be liable for errors in judgment
or neglect or for any acts or omissions that do not constitute gross negligence,
willful misconduct, violation of applicable Law or material breach of this
Operating Agreement, if such person acted in good faith and reasonably believed
such action to be in, or not opposed to, the best interests of the Company. Any
Officer or Manager may consult with counsel, accountants and other professionals
in respect of Company affairs, and provided such Person acts in good faith
reliance upon the advice or opinion of such counsel, accountants or other
professionals, such Person shall not be liable for any loss suffered by the
Company in reliance thereon.

     SECTION 7.3 Right to Indemnification. Subject to the limitations and
conditions as provided in this Article VII, each Person who was or is made a
party or is threatened to be made a party to or is involved in any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or arbitrative (hereinafter a "Proceeding"), or any appeal in
such a Proceeding or any inquiry or investigation that could lead to such a
Proceeding, by reason of the fact that he or she is or was a Manager or Officer
shall be indemnified by the Company to the fullest extent permitted by the
Delaware Act, as the same exist or may hereafter be amended (but, in the case of
any such amendment, only to the extent that such amendment permits the Company
to provide broader indemnification rights than said applicable Law permitted the
Company to provide prior to such amendment), against judgments, penalties
(including excise and similar taxes and punitive damages), fines, settlements
and reasonable expenses (including attorneys' fees) actually incurred by such
Person in connection with such Proceeding, and indemnification under this
Article VII shall continue as to a Person who has ceased to serve in the
capacity which initially entitled such Person to indemnity hereunder. The rights
granted pursuant to this Article VII shall be deemed contract rights, and no
amendment, modification or repeal of this Article VII shall have the effect of
limiting or denying any such rights with respect to actions taken or Proceedings
arising prior to any amendment, modification or repeal. It is expressly
acknowledged that the indemnification provided in this Article VII could involve
indemnification for negligence or under theories of strict liability.
Notwithstanding the foregoing, no Officer or Manager shall be indemnified for
any claim initiated by such Officer or Manager against the Company, except to
the extent such claim is raised to recover an indemnity award to which such
Officer or Manager is entitled pursuant to this Section 7.3.


<PAGE>
                                      -40-


     SECTION 7.4 Advance Payment. Reasonable expenses incurred by a Person of
the type entitled to be indemnified under Section 7.3 who was, is or is
threatened to be made a named defendant or respondent in a Proceeding shall be
paid by the Company in advance of the final disposition of the Proceeding unless
otherwise determined by the Board in the specific case, upon receipt of an
undertaking by or on behalf of such Person to repay such amount if it shall
ultimately be determined that he or she is not entitled to be indemnified by the
Company.

     SECTION 7.5 Indemnification of Employees and Agents. The Company, by
adoption of a resolution of the Board, may indemnify and advance expenses to a
Person who is or was serving as an employee or agent of the Company who is not
and was not a Manager or Officer against any liability asserted against him and
incurred by him in such a capacity or arising out of his status as such a Person
to the same extent and subject to the same conditions under which it may
indemnify and advance expenses to Managers and Officers under this Article VII.

     SECTION 7.6 Appearance as a Witness. Notwithstanding any other provision of
this Article VII, the Company may pay or reimburse reasonable out-of-pocket
expenses incurred by a Manager or Officer in connection with his appearance as a
witness or other participation in a Proceeding at a time when he is not a named
defendant or respondent in the Proceeding.

     SECTION 7.7 Nonexclusivity of Rights. The right to indemnification and the
advancement and payment of expenses conferred in this Article VII shall not be
exclusive of any other right which a Manager, Officer or other Person

transactions contemplated by the Formation Agreement (the "Relief Letter").
Metaldyne agrees to use its reasonable best efforts to follow up with the SEC to

forma financial information as may be reasonably required to comply with the
requirements of Regulation S-X under the Securities Act applicable to a

Operating Agreement, neither the Company nor DaimlerChrysler shall have any
liability to Metaldyne (or any of its Affiliates) for any of the financial
statements required by this Section 8.3 to the extent arising out of or
resulting from Metaldyne's (or any of its Affiliates') use thereof (including,
without limitation, the inclusion of such financial statements in any report or
registration statement filed under the Securities Act or the Exchange Act or any
other offering document used to sell securities of Metaldyne or any of its
Affiliates), and Metaldyne shall indemnify and hold harmless the Company and
DaimlerChrysler from any Losses arising out of or resulting from Metaldyne's (or
any of its Affiliates') use of such financial statements (including, without

registration statement filed under the Securities Act or the Exchange Act or any

federal, foreign, state and local income tax returns.

     SECTION 9.1 Tax Returns. The Company shall prepare and file all necessary
federal, state and local income tax returns, including making the elections

     SECTION 9.2 Tax Elections. The Company shall make any election the Company
may deem appropriate and in the best interests of the Unitholders.

     SECTION 9.3 Tax Matters Partner. DaimlerChrysler shall be the "tax matters
partner" of the Company pursuant to Section 6231(a)(7) of the Code (the "Tax
Matters Partner"). The Tax Matters Partner shall take such action as may be
necessary to cause each other Unitholder to become a "notice partner" within the
meaning of Section 6223 of the Code. The Tax Matters Partner shall inform each
other Unitholder of all significant matters that may come to its attention in
its capacity as Tax Matters Partner by giving notice thereof on or before the
thirtieth (30th) business day after becoming aware thereof and, within that
time, shall forward to each other Unitholder copies of all significant written
communications he may receive in that capacity. The Tax Matters Partner may not
take any action contemplated by Sections 6222 through 6232 of the Code without
the consent of the Board, but this sentence does not authorize the Tax Matters
Partner (or any Manager) to take any action left to the determination of an
individual Unitholder under Sections 6222 through 6232 of the Code.

                                    ARTICLE X

<PAGE>
                                      -44-


          (ii) except with respect to a Transfer pursuant to Article XV, each
     transferee executes a counterpart to this Operating Agreement pursuant to
     which such transferee shall agree to be bound by the provisions of this
     Operating Agreement; and

          (iii) the Transfer otherwise complies with the provisions of this
     Operating Agreement and applicable Laws, including federal and state
     securities Laws.

     (b) If any Unitholder that is a wholly-owned Subsidiary of Metaldyne or
DaimlerChrysler ceases to be a wholly-owned Subsidiary of Metaldyne or
DaimlerChrysler, as the case may be, such Unitholder shall Transfer, to a
Permitted Transferee of Metaldyne or DaimlerChrysler, as the case may be, all
the Units held by it, such Transfer to be effective no later than immediately
prior to the time at which such Unitholder ceases to be a wholly-owned
Subsidiary of Metaldyne or DaimlerChrysler, as the case may be.

     (c) Notwithstanding any of the provisions of this Operating Agreement, no
Transfer of Units shall in any way restrict or diminish any Unitholder's rights
with respect to the put options or call options set forth in Article XV.

     SECTION 10.2 Effect of Assignment.

     (a) Any Unitholder who shall assign any Units or other interest in the
Company shall cease to be a Unitholder of the Company with respect to such Units
or other interest and, except as expressly provided herein, shall no longer have
any rights or privileges of a Unitholder with respect to such Units or other
interest.

     (b) Any Person who acquires in any manner whatsoever any Units or other
interest in the Company, irrespective of whether such Person has accepted and
adopted in writing the terms and provisions of this Operating Agreement, shall
be deemed by the acceptance of the benefits of the acquisition thereof to have
agreed to be subject to and bound by all of the terms and conditions of this
Operating Agreement that any predecessor in such Units or other interest in the
Company of such Person was subject to or by which such predecessor was bound.

     SECTION 10.3 Restrictions on Transfer. In order to permit the Company to
qualify for the benefit of a "safe harbor" under Code Section 7704,
notwithstanding anything to the contrary in this Operating Agreement, no
Transfer of any Unit or economic interest shall be permitted or recognized by
the Company or the Board (within the meaning of Treasury Regulation Section
1.7704-1(d)) if and to the extent that such Transfer would cause the Company to
have more than 100 partners (within the meaning of Treasury Regulation Section
1.7704-1(h), including the look-through rule in Treasury Regulation Section
1.7704-1(h)(3)).

     SECTION 10.4 Transfer Fees and Expenses. The transferor and transferee of

<PAGE>
                                      -45-


     SECTION 10.5 Void Transfers. Any Transfer by any Unitholder of any Units or
other interest in the Company in contravention of this Operating Agreement
(including, without limitation, the failure of the transferee to execute a
counterpart in accordance with Section 10.1(b)) or which would cause the Company
to not be treated as a partnership for U.S. federal income tax purposes shall be
void and ineffectual and shall not bind or be recognized by the Company or any
other party. No purported assignee shall have any right to any profits, losses
or distributions of the Company.

                                   ARTICLE XI

Interest of a Unitholder permitted under the terms of this Operating Agreement,
the transferee shall become a Substituted Unitholder on the effective date of
such Transfer, which effective date shall not be earlier than the date of
compliance with or waiver of the conditions to such Transfer (unless one of the
conditions to such Transfer is that Board or Unitholder approval is required for
the admission of such transferee, in which case such consent must first be
obtained), including executing counterparts of, and becoming a party to, this
Operating Agreement, and such admission shall be shown on the books and records
of the Company.

as an Additional Unitholder upon furnishing to the Board (a) a letter of
acceptance, in form satisfactory to the Board, of all the terms and conditions
of this Operating Agreement, including the power of attorney granted in Section
18.1, and (b) such other documents or instruments as may be necessary or
appropriate to effect such Person's admission as a Unitholder. Such admission
shall become effective on the date on which the Board determines in its sole
discretion that such conditions have been satisfied and when any such admission
is shown on the books and records of the Company.

                                   ARTICLE XII

                    WITHDRAWAL AND RESIGNATION OF UNITHOLDERS

     SECTION 12.1 Withdrawal and Resignation of Unitholders. No Unitholder shall
have the power or right to withdraw or otherwise resign or be expelled from the
Company prior to the dissolution and winding up of the Company pursuant to this
Article XII, except as otherwise expressly permitted by this Operating
Agreement. Notwithstanding that payment on account of a withdrawal may be made
after the effective time of such withdrawal, any completely withdrawing
Unitholder will not be considered a Unitholder for any purpose after the
effective time of such complete withdrawal, and, in the case of a partial
withdrawal, such Unitholder's Capital Account (and corresponding voting and
other rights) shall be reduced for all other purposes hereunder upon the
effective time of such partial withdrawal.


<PAGE>
                                      -46-


     SECTION 12.2 Withdrawal of a Unitholder. No Unitholder shall have the power
or right to withdraw or otherwise resign from the Company except, simultaneous
with the Transfer of all of a Unitholder's Units in a Transfer permitted by this
Operating Agreement and, if such Transfer is to a person or entity that is not a
Unitholder, the admission of such person or entity as a Unitholder pursuant to
Section 11.1. Any purported resignation or withdrawal from the Company in
violation of this Article XII shall be void.

                                  ARTICLE XIII

                           DISSOLUTION AND LIQUIDATION

     SECTION 13.1 Dissolution. The Company shall not be dissolved by the
admission of Additional Unitholders or Substituted Unitholders, or by the death,
retirement, expulsion, bankruptcy or dissolution of a Unitholder or the
occurrence of any other event that terminates the continued membership of a
Unitholder in the Company. The Company may be dissolved, and its affairs may be
wound up, at any time by a determination of the Board. The Company shall be
dissolved, and its affairs shall be wound up, upon the entry of a decree of
judicial dissolution of the Company under Section 18-802 of the Delaware Act or
an administrative dissolution under Section 18-801 of the Delaware Act. Except
as otherwise set forth in this Article XIII, the Company is intended to have
perpetual existence.

     SECTION 13.2 Liquidation and Termination.

     (a) On dissolution of the Company, the Board shall act as liquidator or may
appoint one or more representatives or Unitholders as liquidator. The
liquidators shall proceed diligently to wind up the affairs of the Company, sell
all or any portion of the Company assets for cash or cash equivalents as they
deem appropriate, and make final distributions as provided herein and in the
Delaware Act. The costs of liquidation shall be borne as a Company expense.
Until final distribution, the liquidators shall continue to operate the Company
properties with all of the power and authority of the Board, without further
authorization or consent. The liquidators shall pay, satisfy, or discharge from
Company funds all of the debts, liabilities and obligations of the Company
(including all expenses incurred in liquidation) or otherwise make adequate
provision for payment and discharge thereof (including the establishment of a
cash fund for contingent liabilities in such amount and for such term as the
liquidators may reasonably determine) and shall promptly distribute the
remaining assets to the holders of Units in accordance with Section 4.1(a). Any
non-cash assets will first be written up or down to their Fair Market Value,
thus creating Profit or Loss (if any), which shall be allocated in accordance
with Sections 4.2 and 4.3. In making such distributions, the liquidators shall
allocate each type of asset (i.e., cash, cash equivalents, securities, etc.)
among the Unitholders ratably based upon the aggregate amounts to be distributed
with respect to the Units held by each such Unitholder. Any such distributions
in kind shall be subject to (i) such conditions relating to the disposition and
management of such assets as the liquidators deem reasonable and equitable and
(ii) the terms and conditions of any agreement governing such assets (or the
operation thereof or the holders thereof) at such time. The amount of the
distribution of any asset in kind shall be the Fair Market Value of such asset
reduced (but not below zero) by any liability encumbering such asset or to which
such asset is subject.


<PAGE>
                                      -47-


     (b) The distribution of cash and/or property to a Unitholder in accordance
with the provisions of this Section 13.2 constitutes a complete return to the
Unitholder of its Capital Contributions and a complete distribution to the
Unitholder of its interest in the Company and all the Company's property and
constitutes a compromise to which all Unitholders have consented within the
meaning of the Delaware Act. To the extent that a Unitholder is required to
return funds to the Company pursuant to this Operating Agreement or applicable
Law, such Unitholder shall have no claim against any other Unitholder for those
funds.

     SECTION 13.3 Cancellation of Certificate. On completion of the distribution
of Company assets as provided herein, the Company shall be terminated (and the
Company shall not be terminated prior to such time), and the Board (or such
other Person or Persons as the Delaware Act may require or permit) shall file a
certificate of cancellation with the Secretary of State of Delaware, cancel any
other filings made pursuant to this Operating Agreement that are or should be
canceled, and take such other actions as may be necessary to terminate the
Company. The Company shall be deemed to continue in existence for all purposes
of this Operating Agreement until it is terminated pursuant to this Section
13.3.

     SECTION 13.4 Reasonable Time for Winding Up. A reasonable time shall be
allowed for the orderly winding up of the business and affairs of the Company in
light of prevailing market conditions and the liquidation of its assets pursuant
to Section 13.2 in order to minimize any losses otherwise attendant upon such
winding up.

     SECTION 13.5 Return of Capital. The liquidators shall not be personally
liable for the return of Capital Contributions or any portion thereof to the
Unitholders (it being understood that any such return shall be made solely from
Company assets).

     SECTION 13.6 Reserves Against Distributions. The Board shall have the right
to withhold from Distributions payable to any Unitholder under this Operating
Agreement (other than Tax Distributions) amounts sufficient to pay and discharge
any reasonably anticipated contingent liabilities of the Company. Any amounts
remaining after payment and discharge of any such contingent liabilities of the
Company will be paid to the Unitholders from whom the Distributions were
withheld.

                                   ARTICLE XIV

                                    VALUATION

     SECTION 14.1 Determination. Subject to Sections 4.5 and 14.2, the Fair
Market Value of the assets of the Company will be determined by the Board (or,
if pursuant to Section 13.2, the liquidators) in its good faith judgment in such
manner as its deems reasonable and using all factors, information and data
deemed to be pertinent.

     SECTION 14.2 Fair Market Value. For purposes of this Operating Agreement,
the "Fair Market Value" of (i) a specific Company asset will mean the amount
which the Company would receive in an all-cash sale of such asset (assuming that
the asset is free and clear of all Liens) in an arm's-length transaction with an
unaffiliated third party consummated on the day immediately pre-


<PAGE>
                                      -48-


ceding the date on which the event occurred which necessitated the determination
of the Fair Market Value (and after giving effect to any transfer taxes payable
in connection with such sale); and (ii) the Company will mean the amount which
the Company would receive in an all-cash sale of all of its assets and
businesses as a going concern (free and clear of all Liens and after payment of
indebtedness for borrowed money) in an arm's-length transaction with an
unaffiliated third party consummated on the day immediately preceding the date
on which the event occurred which necessitated the determination of the Fair
Market Value (assuming that all of the proceeds from such sale were paid
directly to the Company other than an amount of such proceeds necessary to pay
transfer taxes payable in connection with such sale, which amount will not be
received or deemed received by the Company). After a determination of the Fair
Market Value of the Company is made as provided above, the Fair Market Value of
a Unit will be determined by making a calculation reflecting the cash
distributions which would be made to the Unitholders in accordance with this
Operating Agreement in respect of such Unit if the Company were deemed to have
received such Fair Market Value in cash and then distributed the same to the
Unitholders in accordance with the terms of this Operating Agreement incident to
the liquidation of the Company after payment to all of the Company's creditors
from such cash receipts other than payments to creditors who hold evidence of
indebtedness for borrowed money, the payment of which is already reflected in
the calculation of the Fair Market Value of the Company, and assuming that all
of the convertible debt and other convertible securities were repaid or
converted (whichever yields more cash to the holders of such convertible
securities) and all options to acquire Units (whether or not currently
exercisable) that have an exercise price below the Fair Market Value of such
Units were exercised and the exercise price therefor paid. Except as otherwise
provided herein or in any agreement, document or instrument contemplated hereby,
any amount to be paid under this Operating Agreement by reference to the Fair
Market Value shall be paid in full in cash, and any Unit being transferred in
exchange therefor will be transferred free and clear of all Liens.

                                   ARTICLE XV

                              CALL AND PUT OPTIONS

"Metaldyne Call Option").

     (b) Conditions to Exercise. Subject to Section 15.4, Metaldyne shall have

          (ii) Class B Units. The aggregate purchase price for the Class B Units
     shall be $185,000,000 the "Class B Units Purchase Price"). The Class B
     Units Purchase Price shall be payable at the Metaldyne Call Option Closing
     as follows: (A) 48% of the Class B Units Purchase Price shall be payable in
     cash by wire transfer of immediately available funds to a single account
     designated in writing by DaimlerChrysler (who shall act as paying agent for
     all Class B Unitholders) at least one Business Day prior to the Metaldyne
     Call Option Closing; and (B) the remainder of the Class B Units Purchase
     Price shall be payable in (1) Senior Subordinated Notes having an aggregate
     stated principal amount equal to 17.16% of the Class B Units Purchase Price

     preference equal to 34.84% of the Class B Units Purchase Price.

     (d) Exercise and Closing.

          (i) Metaldyne shall exercise the Metaldyne Call Option (provided that
     the Metaldyne Call Option has not been suspended or terminated pursuant to
     Section 15.4) by delivering to DaimlerChrysler (as representative of all
     Class A Unitholders and Class B Unitholders) written notice of the exercise
     of the Metaldyne Call Option (the "Metaldyne Call Option Notice"). The date
     on which DaimlerChrysler receives the Metaldyne Call Option Notice shall be
     referred to as the "Metaldyne Call Option Notice Date".

          (ii) Promptly following the exercise of the Metaldyne Call Option
     pursuant to Section 15.1(d)(i), each of Metaldyne and the other Unitholders

     or the DaimlerChrysler Call Option Closing.

          (c) The DaimlerChrysler Call Option shall not be exercisable if (i)
     Metaldyne has exercised the Metaldyne Call Option (and such exercise has
     not been rescinded) in accordance with Section 15.1 (provided, however,

          (c) use its commercially reasonable efforts to preserve intact its
     current relationships and pricing with suppliers to the Company; and

          (d) permit the Company in cooperation with Metaldyne to conduct and
     prepare a report of Inventory at December 31, 2002 and at June 30, 2003.

     SECTION 16.2 Certain Obligations of DaimlerChrysler During and After JV

DaimlerChrysler shall:

          (a) fund any capital expenditures contractually committed by the
     Company during the JV Period but billed to the Company after the JV Period;

          (b) fund any capital expenditure for the CS or LX program not funded
     during the JV Period but necessary for the production needs of
     DaimlerChrysler to the extent presently planned (the anticipated funding
     for these programs is as shown in the Operating Budget and Capital Plan);

          (c) satisfy directly, or reimburse the Company, for any and all
     Indebtedness or other liabilities or obligations of the Company as of the
     JV Termination Date, whether or not shown on the Final Balance Sheet,
     except for trade payables related to purchases of Inventory shown on the

                                  ARTICLE XVII

                         NET WORKING CAPITAL ADJUSTMENT

     SECTION 17.1 Net Working Capital Adjustment. Within sixty (60) days after
the Metaldyne Call Option Closing, Metaldyne shall prepare and deliver to
DaimlerChrysler a draft balance


<PAGE>
                                      -59-


sheet of the Company as of the date of the Metaldyne Call Option Closing (the
"Final Balance Sheet"), which shall be prepared in accordance with the
principles set forth on Schedule 2.7 to the Formation Agreement, and a draft
calculation of the Final Net Working Capital based on such draft Final Balance
Sheet.

     DaimlerChrysler shall have a period of twenty (20) days following receipt
of the draft Final Balance Sheet and the draft calculation of the Final Net
Working Capital from Metaldyne within which to review the draft Final Balance
Sheet and the draft calculation of the Final Net Working Capital. If
DaimlerChrysler has any objections to the draft Final Balance Sheet and/or the
draft calculation of the Final Net Working Capital, it will deliver to Metaldyne
a detailed statement describing such objections (the "DaimlerChrysler Objection
Notice") within such twenty (20) day review period. DaimlerChrysler and
Metaldyne will use their respective commercially reasonable efforts to resolve
any such objections set forth in the DaimlerChrysler Objection Notice. If a
final resolution is not obtained within a period of twenty (20) days following
delivery of a DaimlerChrysler Objection Notice, DaimlerChrysler and Metaldyne
will select and jointly engage a nationally-recognized accounting firm mutually
acceptable to them (the "Accountant") to resolve any remaining objections. If
DaimlerChrysler and Metaldyne are unable to agree on the choice of an accounting
firm, they will select a nationally-recognized accounting firm by lot (after
excluding their respective independent public accountants). The Accountant shall
promptly, but in no event later than twenty (20) days following its engagement
by DaimlerChrysler and Metaldyne, deliver to DaimlerChrysler and Metaldyne its
decision as to any remaining objections set forth in the DaimlerChrysler
Objection Notice. The decision of the Accountant shall be final and binding on
DaimlerChrysler and Metaldyne.

     Metaldyne will revise the draft Final Balance Sheet and the draft
calculation of the Final Net Working Capital as appropriate to reflect the
resolution of any objections set forth in the DaimlerChrysler Objection Notice
(as agreed upon by DaimlerChrysler and Metaldyne or as determined by the
Accountant) and deliver them to DaimlerChrysler within twenty (20) days after
the final resolution of such objections. Such revised drafts shall be the Final
Balance Sheet and the Final Net Working Capital, respectively.

     In the event that the Final Net Working Capital is less than zero, the
Company shall assign to DaimlerChrysler, and DaimlerChrysler shall assume from
the Company, trade payables in the amount of such shortfall within 20 days
following the final resolution of the Final Net Working Capital.

     If any unresolved objections are submitted to the Accountant for resolution
as provided above, the fees and expenses of the Accountant shall be borne 50% by
DaimlerChrysler and 50% by Metaldyne. Metaldyne will provide reasonable access
to the work papers necessary for the preparation of the Final Balance Sheet and
the calculation of the Final Net Working Capital to DaimlerChrysler and the
Accountant during the preparation of the Final Balance Sheet and the calculation
of the Final Net Working Capital by Metaldyne, the review by DaimlerChrysler of
the Final Balance Sheet and the calculation of the Final Net Working Capital,
and the resolution of any objections with respect thereto.

                                  ARTICLE XVIII

                               GENERAL PROVISIONS

     SECTION 18.1 Power of Attorney. (a) Each Unitholder hereby constitutes and

acknowledge, deliver, file and record in the appropriate public offices (i) this
Operating Agreement, all certificates, and other instruments and all amendments
(in the manner set forth herein) thereof in accordance with the terms hereof
which the Board deems appropriate or necessary to form, qualify, or continue the
qualification of, the Company as a limited liability company in the State of
Delaware and in all other jurisdictions in which the Company may conduct
business or own property; (ii) all conveyances and other instruments or
documents which the Board deems appropriate or necessary to reflect the
dissolution and liquidation of the Company pursuant to the terms of this
Operating Agreement, including a certificate of cancellation; and (iii) all
instruments relating to the admission withdrawal, or substitution of any
Unitholder pursuant to Articles XI and XII.

     (b) The foregoing power of attorney is irrevocable and coupled with an
interest, and shall survive the death, disability, incapacity, dissolution,
bankruptcy, insolvency, or termination of any Unitholder and the Transfer of all
or any portion of his or its Interest and shall extend to such Unitholder's
heirs, successors, assigns, and personal representatives.

     SECTION 18.2 Amendments. This Operating Agreement may be amended from time
to time by a written instrument by the holders of at least 66 2/3% of the
outstanding Class A Units; provided that no amendment or modification pursuant
to this Section 18.2 that would adversely affect any class or series of Units in
a manner different than other classes or series of Units (as the case may be)
shall be effective against the holders of such class or series of Units (as the
case may be) without the prior written consent of holders of a majority of the
outstanding Units of such class so adversely affected thereby; provided,
further, that no amendment or modification pursuant to this Section 18.2 that
would affect the rights of a Unitholder or group of Unitholders specifically
granted such rights by name shall be modified without the consent of that
Unitholder (or a majority of that group of Unitholders).

     SECTION 18.3 Title to Company Assets. Company assets shall be deemed to be
owned solely by the Company as an entity, and no Unitholder, individually or
collectively, shall have any ownership interest in such Company assets or any
portion thereof. Legal title to any or all the Company assets may be held in the
name of the Company or one or more nominees, as the Board may determine. The
Board hereby declares and warrants that any Company assets for which legal title
is held in its name or the name of any nominee shall be held in trust by the
Board or such nominee for the use and benefit of the Company in accordance with
the provisions of this Operating Agreement. All Company assets shall be recorded
as the property of the Company on its books and records, irrespective of the
name in which legal title to such Company assets is held. The interests of
Unitholders in the Company shall constitute personal property.

                                      -61-


     SECTION 18.4 Remedies. Each Unitholder and the Company shall have all
rights and remedies set forth in this Operating Agreement and all legal and
equitable rights and remedies which such Person has been granted at any time
under any other agreement or contract and all of the rights which such Person
has at law or in equity. Any Person having any rights under any provision of
this Operating Agreement or any other agreements contemplated hereby shall be

security), to recover damages by reason of any breach of any provision of this
Operating Agreement and to exercise all other rights under applicable Law.

     SECTION 18.5 Successors and Assigns. All covenants and agreements contained
in this Operating Agreement shall bind and inure to the benefit of the parties
hereto and their respective heirs, executors, administrators, successors, legal
representatives and permitted assigns, whether so expressed or not.

     SECTION 18.6 Severability. Whenever possible, each provision of this
Operating Agreement will be interpreted in such manner as to be effective and
valid under applicable Law, but if any provision of this Operating Agreement is
held to be invalid, illegal or unenforceable in any respect under any applicable
Law or rule in any jurisdiction, such invalidity, illegality or unenforceability
will not affect any other provision or the effectiveness or validity of any
provision in any other jurisdiction, and this Operating Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

     SECTION 18.7 Notice to Unitholder of Provisions. By executing this
Operating Agreement, each Unitholder acknowledges that it has actual notice of
(a) all of the provisions hereof (including the restrictions on the transfer set
forth herein) and (b) all of the provisions of the Certificate.

     SECTION 18.8 Counterparts. This Operating Agreement may be executed
counterparts each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

     SECTION 18.9 Consent to Jurisdiction; Waiver of Jury Trial. Each Unitholder
irrevocably and unconditionally submits to the exclusive jurisdiction of the
United States District Court for the State of Delaware and the state courts of
the State of Delaware for the purposes of any suit, action or other proceeding
arising out of this Operating Agreement or any transaction contemplated hereby.
Each Unitholder further agrees that service of any process, summons, notice or
document by United States certified or registered mail to such Unitholder's
respective address set forth in the Company's books and records or such other
address or to the attention of such other Person as the recipient party has
specified by prior written notice to the sending party shall be effective
service of process in any action, suit or proceeding in Delaware with respect to
any matters to which it has submitted to jurisdiction as set forth above in the
immediately preceding sentence. Each Unitholder irrevocably and unconditionally
waives any objection to the laying of venue of any action, suit or proceeding
arising out of this Operating Agreement or the transactions contemplated hereby
in the United States District Court for the State of Delaware or the state
courts of the State of Delaware and hereby irrevocably and unconditionally
waives and agrees not to plead or claim in any such court that any such action,



<PAGE>
                                      -62-


suit or proceeding brought in such court has been brought in an inconvenient
forum. Each party agrees that a final judgment in any such suit, action or
proceeding brought in any such court shall be conclusive and binding upon such
party and may be enforced in any other courts to whose jurisdiction such party
is or may be subject, by suit upon judgment. THE PARTIES ALSO WAIVE ANY BOND OR
SURETY OR SECURITY UPON SUCH BOND WHICH MIGHT, BUT FOR THIS WAIVER, BE REQUIRED
OF ANY OF THE OTHER PARTIES. THE SCOPE OF THIS WAIVER IS INTENDED TO BE
ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT
RELATE TO THE SUBJECT MATTER OF THIS OPERATING AGREEMENT, INCLUDING, WITHOUT
LIMITATION, CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER
COMMON LAW AND STATUTORY CLAIMS. THE PARTIES ACKNOWLEDGE THAT THIS WAIVER IS A
MATERIAL INDUCEMENT TO ENTER INTO THIS OPERATING AGREEMENT, THAT EACH HAS
ALREADY RELIED ON THE WAIVER IN ENTERING INTO THIS OPERATING AGREEMENT AND THAT
EACH WILL CONTINUE TO RELY ON THE WAIVER IN THEIR RELATED FUTURE DEALINGS. THE
PARTIES FURTHER WARRANT AND REPRESENT THAT EACH HAS REVIEWED THIS WAIVER WITH
ITS LEGAL COUNSEL, AND THAT EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL
RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. THIS WAIVER IS IRREVOCABLE,
MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THE WAIVER
SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS
TO THIS OPERATING AGREEMENT OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO
THE TRANSACTIONS COMPLETED HEREBY. IN THE EVENT OF LITIGATION, THIS OPERATING
AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

     SECTION 18.10 Descriptive Headings; Interpretation. The descriptive
headings of this Operating Agreement are inserted for convenience only and do
not constitute a substantive part of this Operating Agreement. Whenever required
by the context, any pronoun used in this Operating Agreement shall include the
corresponding masculine, feminine or neuter forms, and the singular form of
nouns, pronouns and verbs shall include the plural and vice versa. The use of
the word "including" in this Operating Agreement shall be by way of example
rather than by limitation. Reference to any agreement, document or instrument
means such agreement, document, or instrument as amended or otherwise modified
from time to time in accordance with the terms thereof, and if applicable
hereof. Without limiting the generality of the immediately preceding sentence,
no amendment or other modification to any agreement, document or instrument that
requires the consent of any Person pursuant to the terms of this Operating
Agreement or any other agreement will be given effect hereunder unless such
Person has consented in writing to such amendment or modification. Wherever
required by the context, references to a Fiscal Year shall refer to a portion
thereof. The use of the words "or," "either," and "any" shall not be exclusive.
The parties hereto have participated jointly in the negotiation and drafting of
this Operating Agreement. In the event an ambiguity or question of intent or
interpretation arises, this Operating Agreement shall be construed as if drafted
jointly by the parties hereto, and no presumption or burden of proof shall arise
favoring or disfavoring any party by virtue of the authorship of any of the
provisions of this Operating Agreement. Wherever a conflict exists between this
Operating Agreement and any other agreement, this Operating Agreement shall
control but solely to the extent of such conflict.


<PAGE>
                                      -63-


     SECTION 18.11 Applicable Law. This Operating Agreement shall be governed
by, and construed in accordance with, the Laws of the State of Delaware, without
giving effect to any choice of law or conflict of law rules or provisions
(whether of the State of Delaware or any other jurisdiction) that would cause
the application of the Laws of any jurisdiction other than the State of
Delaware. Any dispute relating hereto shall be heard in the state or federal
courts of Delaware, and the parties agree to jurisdiction and venue therein.

     SECTION 18.12 Addresses and Notices. All notices, requests, instructions,
demands, or other communications to be given or delivered under or by reason of
the provisions of this Operating Agreement shall be in writing and shall be
deemed to have been duly given or made (a) on the date of receipt if given in
person, (b) on the date of transmission if sent by telecopy or e-mail with
receipt of delivery confirmation, (c) three (3) Business Days after being
deposited in the U.S. mail, certified or registered mail (postage prepaid,
return receipt requested), or (d) one (1) Business Day following sending by
overnight delivery via an internationally recognized courier service, in each
case, to the applicable party at the following addresses or facsimile numbers
(or at such other address or facsimile number for a party as shall be specified
by like notice). Such notices, demands, and other communications shall be sent
to the address for such recipient set forth in the Company's books and records,
or to such other address or to the attention of such other Person as the
recipient party has specified by prior written notice to the sending party. Any
notice to the Board or the Company shall be deemed given if received by the
Board at the principal office of the Company designated pursuant to Section 2.5.

     SECTION 18.13 Creditors. None of the provisions of this Operating Agreement
shall be for the benefit of or enforceable by any creditors of the Company or
any of its Affiliates, and no creditor who makes a loan to the Company or any of
its Affiliates may have or acquire (except pursuant to the terms of a separate
agreement executed by the Company in favor of such creditor) at any time as a
result of making the loan any direct or indirect interest in Company Profits,
Losses, Distributions, capital or property other than as a secured creditor.

     SECTION 18.14 Waiver of Certain Rights. No failure by any party to insist
upon the strict performance of any covenant, duty, agreement, or condition of
this Operating Agreement or to exercise any right or remedy consequent upon a
breach thereof shall constitute a waiver of any such breach or any other
covenant, duty, agreement, or condition.

     SECTION 18.15 Further Action. The parties shall execute and deliver all
documents, provide all information, and take or refrain from taking such actions
as may be necessary or appropriate to achieve the purposes of this Operating
Agreement.

     SECTION 18.16 Entire Agreement. This Operating Agreement, those documents
expressly referred to herein, the other documents of even date herewith, and the
other Transaction Documents constitute the entire agreement and understanding
among the parties thereto and supersede and preempt any prior understandings,
agreements, representations or arrangements written, or oral, by or among the
parties hereto.


<PAGE>
                                      -64-


     SECTION 18.17 Delivery by Facsimile. This Operating Agreement, the
agreements referred to herein, and each other agreement or instrument entered
into in connection herewith or therewith or contemplated hereby or thereby, and
any amendments hereto or thereto, to the extent signed and delivered by means of
a facsimile machine, shall be treated in all manner and respects as an original
agreement or instrument and shall be considered to have the same binding legal
effect as if it were the original signed version thereof delivered in person. At
the request of any party hereto or to any such agreement or instrument, each
other party hereto or thereto shall re-execute original forms thereof and
deliver them to all other parties. No party hereto or to any such agreement or
instrument shall raise the use of a facsimile machine to deliver a signature or
the fact that any signature or agreement or instrument was transmitted or
communicated through the use of a facsimile machine as a defense to the
formation or enforceability of a contract and each such party forever waives any
such defense.

     SECTION 18.18 Survival. Sections 4.6, 6.1, 7.1 and 7.2 shall survive and
continue in full force in accordance with its terms notwithstanding any
termination of this Operating Agreement or the dissolution of the Company.

     SECTION 18.19 Dispute Resolution Procedures. All controversies, claims or
disputes between the Unitholders or between the Company and any Unitholder that
arise out of or relate to this Operating Agreement (a "Dispute"), will be
resolved in accordance with the provisions of this Section 18.19.
Notwithstanding anything to the contrary contained in this Section 18.19, (i)
nothing in this Section 18.19(i) will limit the ability of the directors and
officers of any Unitholder from communicating directly with the directors and
officers of the other Unitholders and (ii) no act of the Board or failure to act
by the Board shall constitute a Dispute or form the basis for a Dispute subject
to the provisions of this Section 18.19.

          (a) Dispute Notice and Response. Any Unitholder may give another
     Unitholder written notice (a "Dispute Notice") of any Dispute which has not
     been resolved in the normal course of business. The Dispute Notice will
     include a statement setting forth the position of the Unitholder giving
     such notice, a summary of the arguments supporting such position and, if
     applicable, the relief sought. At the next regular or special meeting of
     the Board following the delivery of the Dispute Notice, the Board will
     attempt in good faith to resolve the Dispute. If the Dispute remains
     unresolved following such meeting, the initiating Unitholder may request in
     writing to the other Unitholders (a "Vice President Notice") that the
     Dispute be resolved by officers of the Unitholders (at the Vice President
     level or above and having experience in the subject matter of the Dispute)
     pursuant to Section 18.19(b).

          (b) Negotiation Between Vice Presidents.

               (i) Within 10 Business Days after delivery of a Vice President
          Notice, officers of the Unitholders (which officers shall hold the
          office of Vice President or a higher office and shall have experience
          in the subject matter of the Dispute) will meet or communicate by
          telephone at a mutually acceptable time and place, and thereafter as
          often as they reasonably deem necessary, and will negotiate in good
          faith to attempt to resolve the Dispute that is the subject of such
          Dispute Notice. If such Dispute has not been resolved within 180
          calendar days after delivery of the Dispute Notice, each Unitholder
          will be permitted to take such ac-


<PAGE>
                                      -65-


          tions at law or in equity as it is otherwise permitted to take or as
          may be available under applicable Law.

               (ii) All negotiations between the Vice Presidents or other
          officers pursuant to this Section 18.19(b) will be treated as
          compromise and settlement negotiations. Nothing said or disclosed, nor
          any document produced, in the course of such negotiations which is not
          otherwise independently discoverable will be offered or received as
          evidence or used for impeachment or for any other purpose in any
          current or future arbitration or litigation.

          (c) Right to Equitable Relief Preserved. Notwithstanding anything in
     this Operating Agreement to the contrary, any Unitholder or the Company may
     at any time seek from any court of the United States located in the State
     of Delaware or from any Delaware state court, any interim, provisional or
     injunctive relief that may be necessary to protect the rights or property
     of such party or maintain the status quo before, during or after the
     pendency of the negotiation process or the arbitration proceeding or any
     other proceeding contemplated by Section 18.19(b).

     SECTION 18.20 Public Statements. Subject to applicable Law, including the
requirements of the Exchange Act, each of the parties agree that, from and after
the date hereof through the earlier of the termination of this Operation
Agreement and January 1, 2005, no public release or announcement concerning this
Operating Agreement, the Related Agreements or the transactions contemplated
hereby or thereby shall be issued without the joint consent with the other
parties, such consent not to be unreasonably withheld or delayed, and, in
connection therewith, the issuing party shall provide each other with a
reasonable opportunity to review such proposed release prior to publication
thereof. Notwithstanding the foregoing, if any party is required to disclose the
terms of this Operating Agreement or any Related Agreement pursuant to the
Securities Act or the Exchange Act, it shall use its commercially reasonable
efforts to avoid any such disclosure and shall, whenever reasonably practicable,
consult with the other parties concerning the timing and content of such
disclosure before the same is made.
