     (a) If Net Working Capital, as finally determined as hereinafter provided
   in this Section 3.3, is less than $965,000, the Purchase Price shall be
   deemed reduced by such difference and Sellers shall pay Buyer an amount in
   cash equal to such difference. If Net Working Capital, as finally determined,

   papers of Buyer utilized in preparing the Preliminary Statement and shall
   have full access to the

                                     - 12 -

   books, records, properties and personnel of Buyer for purposes of verifying
   the accuracy and fairness of the presentation of Net Working Capital in the
   Preliminary Statement. The Preliminary Statement shall be binding on Sellers,
   unless Metaldyne presents to Buyer written notice of disagreement within 30
   days after receipt of the Preliminary Statement specifying in reasonable
   detail the nature and extent of the disagreement.

     (d) If Buyer and Sellers are unable to resolve any such disagreement within
   15 days after Buyer received notice of such disagreement, the disagreement
   shall be referred for final determination to an independent accounting firm
   as the parties shall mutually designate. The accounting firm so designated to
   make the final determination is hereinafter referred to as the "INDEPENDENT
   ACCOUNTANTS."

     (e) Net Working Capital shall be deemed to have been finally determined
   upon the first to occur of (i) written acceptance of the Preliminary
   Statement by Metaldyne, (ii) Metaldyne's failure to object thereto within 30
   days of receipt thereof, or (iii) notification by the Independent Accountants
   of their final determination thereof.

   course of Plan activities) has been brought or, to the knowledge of the
   Sellers, threatened against or with respect to any Benefit Plan.

     (a) sell, lease, license or otherwise dispose of any material amount of
   assets, securities or property of the Acquired Business, taken as a whole,
   except pursuant to existing contracts or commitments or otherwise in the

   Taxes;

   Acquired Business;

                                     - 18 -

     (f) (i) take any action that would make any representation and warranty of
   Sellers hereunder inaccurate in any material respect at, or as of any time
   prior to, the Closing Date or (ii) omit to take any action necessary to
   prevent any such representation or warranty from being materially inaccurate
   in any respect at any such time; or

     (g) authorize, or commit or agree to take, any of the foregoing actions.

     SECTION 6.2. ACCESS TO INFORMATION. From the date of this Agreement until

the "BUYER REPRESENTATIVES") reasonable access, upon reasonable notice and
during normal business hours, to the offices and other facilities and to the
books and records of the Acquired Business and shall cause the Seller
Representatives to furnish Buyer and the Buyer Representatives with such
financial and operating data and such other information with respect to the
Acquired Business as Buyer may from time to time reasonably request.

     SECTION 6.3. REPORTS. During the period from the date of this Agreement to

Business Day following the end of each calendar month following the date of this
Agreement.

     SECTION 6.4. CONSULTATION WITH BUYER. During the period from the date of

entering into any contract with respect to the Purchased Assets, Assumed
Liabilities or Transferred Employees that has a duration of over 90 days or that
would be reasonably likely to result in payments by or to Buyer in excess of
$250,000. In furtherance of the foregoing, Sellers covenant that they will
consult with and provide all relevant documents to Buyer between the date of
execution of this Agreement and the Closing Date with respect to all matters
relating to communications and negotiations, if any, with the United Automobile
Workers of America Local No. 36 regarding the terms and conditions of employment
of the Transferred Employees at the Fittings Facility and procedures for
negotiations thereof.

                                  ARTICLE VII.

                         COVENANTS OF BUYER AND SELLERS

     The parties hereto agree that:

     SECTION 7.1. COMMERCIALLY REASONABLE EFFORTS. Subject to the terms and
conditions of this Agreement, Buyer and Sellers will use all commercially
reasonable efforts to take, or cause to be taken, all necessary or appropriate
actions and to do, or cause to be done, all

                                     - 19 -

things necessary or appropriate to satisfy the conditions to closing set forth

conditions set forth in this Agreement including, without limitation, to use
commercially reasonable efforts to obtain any consents necessary to be obtained
prior to and after the Closing Date.

     SECTION 7.2. CERTAIN FILINGS. Prior to and after the Closing Date, Buyer
and Sellers shall use their commercially reasonable efforts to cooperate with
one another in (i) determining whether any action by or in respect of, or filing
with, any Governmental Authority is required, or any actions, consents,
approvals or waivers are required to be obtained from parties to any material
contracts, in connection with the consummation of the Transactions, and (ii)
taking such actions or making any such filings, furnishing information required
in connection therewith and seeking timely to obtain any such actions, consents,
approvals or waivers.

     SECTION 7.3. PUBLIC ANNOUNCEMENTS. Buyer and Sellers shall consult with
each other before issuing any press release or making any public statement with
respect to this Agreement or the Transactions and shall not issue any such press
release or make any such public statement without the consent of the other
parties hereto.

     SECTION 7.4. NOTICES OF CERTAIN EVENTS. Buyer and Sellers shall promptly
notify the other of:

     (a) any written notice or other written communication from any Person
   alleging that the consent of such Person is or may be required in connection
   with the Transactions;

     (b) any written notice or other written communication from any Governmental
   Authority in connection with the Transactions;

     (c) any Actions, suits, claims, investigations or proceedings commenced or,
   to its knowledge, threatened against, relating to or involving or otherwise
   affecting Sellers or the Acquired Business that, if pending on the date of
   this Agreement, would have been required to be disclosed pursuant to Section
   4.7 hereof, or that relate to the consummation of the Transactions;

     (d) the occurrence or non-occurrence of any fact or event which would be
   reasonably likely:

         (i) to cause any representation or warranty contained in this Agreement
     to be untrue or inaccurate in any material respect at any time from the
     date hereof to the Closing Date, or

         (ii) to cause any covenant, condition or agreement under this Agreement
     not to be complied with or satisfied; and

                                     - 20 -

     (e) any failure of Buyer or any Seller, as the case may be, to comply with
   or satisfy any covenant, condition or agreement to be complied with or
   satisfied by it hereunder; provided, however, that no such notification shall
   affect the representations or warranties of any party or the conditions to
   the obligations of any party hereunder.

     SECTION 7.5. CONFIDENTIALITY. Prior to the Closing Date and after any
termination of this Agreement, Buyer and each Seller will hold, and will use all
commercially reasonable efforts to cause its officers, directors, employees,
accountants, counsel, consultants, advisors and agents to hold, in confidence
all confidential documents and information concerning the other party furnished
to it or its Affiliates in connection with the Transactions.

     SECTION 7.6. PLANS.

     (a) Employment Status. Buyer shall employ all of the Employees who are
   actively employed by the Acquired Business on the Closing Date immediately
   after giving effect to the Transactions (each such employee being hereafter
   referred to as a "TRANSFERRED EMPLOYEE"), it being agreed that persons who
   are on layoff or leave and who have a right to return to work at the Acquired
   Business or who are on short-term (not more than six months) medical
   disability (including pregnancy leave) who do not thereafter become eligible
   for long-term medical disability or other authorized leave (such as military,
   family or other leaves where return to work is subject to statutory
   requirements) are to be considered Employees who are actively employed, and
   it is also agreed that persons on long-term medical disability or whose
   short-term medical disability thereafter becomes a long-term medical
   disability and persons whose employment has terminated or will terminate
   prior to the Closing Date without any right to return to work are not to be
   considered Employees who are actively employed; provided, however, that the
   provisions of this Section 7.6(a) shall not be construed to limit the ability
   of the Buyer to terminate any such Employee at any time for any reason. From
   and after the Effective Time, Buyer shall also assume responsibility to
   provide Former Employees with disability benefits in the same manner and to
   the same extent as such Former Employees would have been entitled to receive
   under Sellers' disability plans and Buyer shall assume the responsibility to
   provide Transferred Employees and Former Employees with continuing benefits
   and coverage required, if any, under Section 4980B of the Code and part 6 of
   Subtitle B of Title I of ERISA. Sellers hereby represent and warrant to Buyer
   that Schedule 7.6(a) hereto contains a true and accurate list of all
   Transferred Employees, and (i) each of their respective compensation
   arrangements (ii) the date of hire of each such employee; and (iii) any
   employment, severance or other compensation agreement with any such employee.
   For purposes of this Agreement, the terms "layoff," "right to return to
   work," "short-term disability," "long-term disability" and "pregnancy leave"
   shall be construed in accordance with the personnel policies of Sellers and
   the collective bargaining agreements covering Transferred Employees, if
   applicable, both as in effect as of the date hereof.

                                     - 21 -

     (b) Pension Plans. (i) Effective as of December 31, 2002, except for
   Employees included in the United Auto Workers Hi-Vol Livonia collective
   bargaining group (the "UNION EMPLOYEES") who participate in the MascoTech,
   Inc. Master Hourly Employees Pension Plan (the "UNION PLAN"), the Transferred
   Employees have ceased to participate in, or accrue any further benefits
   under, any tax-qualified defined benefit plan of Sellers or their
   Subsidiaries; provided, however, that, to the extent permitted by applicable
   law, and, except as otherwise elected in subsection (ii) below, the benefits
   of the Union Employees in the Union Plan shall be increased by crediting the
   service of such Transferred Employees with Buyer and its Subsidiaries through
   the earlier of (A) December 31, 2003 and (B) the Plan Effective Date (as
   defined below). Effective as of the Effective Time, except as otherwise
   provided herein, Buyer shall not have any responsibility for contributing to
   or under any tax-qualified defined benefit plan maintained by Sellers or
   their Subsidiaries. Except as otherwise provided below, all assets and
   liabilities of any tax-qualified defined benefit plan maintained by Sellers
   or any of their Subsidiaries attributable to any Employee or Former Employee
   of the Acquired Business shall be retained by Sellers. Notwithstanding the
   foregoing, if (A) on or before December 31, 2003, Buyer enters into a binding
   collective bargaining agreement (the "UNION AGREEMENT") with respect to the
   Union Employees; (B) such Union Agreement provides for the Union Employees to
   participate in a defined benefit pension plan sponsored by Buyer or its
   Subsidiaries (the "BUYER UNION PLAN"); and (C) the Buyer Union Plan credits
   service with Sellers for purposes of determining benefit accruals for Union
   Employees, then the following subsections (ii), (iii), (iv) and (v) shall
   apply.

     (ii) Buyer shall, as soon as practicable after entering into the Union
   Agreement, notify Metaldyne thereof and advise Metaldyne as to whether the
   Union Agreement meets the requirements set forth in the last sentence of
   Section 7.6(b)(i) and, if applicable, of the date that is the Plan Effective
   Date. Buyer shall establish or maintain, as of the date the Buyer Union Plan
   or any other replacement plan becomes effective pursuant to the collective
   bargaining agreement with the Employees (the "PLAN EFFECTIVE DATE"), a
   tax-qualified defined benefit plan (the "BUYER'S PENSION PLAN") for Employees
   and Former Employees participating in the Union Plan. Subject to the transfer
   of assets described in Section 7.6(b)(iii), the Buyer's Pension Plan shall
   assume the liabilities as of the Plan Effective Date for the benefits of all
   Employees and Former Employees participating in the Union Plan.

     (iii) On a day which is within 60 days after the later of (i) the date upon
   which the Buyer delivers to Metaldyne notice that the Buyer's actuaries,
   pursuant to Section 7.6(b)(v) hereof, have reviewed the calculations of
   Sellers' actuaries and are satisfied that such calculations are in accordance
   with this Agreement (or have failed to do so within the 60 day period
   provided for in Section 7.6(b)(v)), or (ii) the day upon which the Buyer
   delivers to Metaldyne a favorable IRS determination letter or an opinion of
   the Buyer's counsel, reasonably satisfactory to Metaldyne's counsel, to the
   effect that the terms of the Buyer's Pension Plan and its related trust
   qualify, as to form, under Section 401(a) and Section 501(a) of the Code,
   Sellers shall cause the trustee under the Un-

                                     - 22 -

   ion Plan ("SELLERS' TRUSTEE") to transfer to the trustee of the Buyer's
   Pension Plan (the "BUYER'S TRUSTEE") cash assets or such other assets
   agreeable to the Buyer's Trustee and Sellers' Trustee in an amount equal to
   the amount necessary to satisfy the applicable requirements of Sections
   414(1) and 401(a)(12) of the Code, computed based on the actuarial
   assumptions used by Sellers for financial disclosure purposes for the most
   recently completed fiscal year ending on or before the date of such transfer.

     (iv) The amount transferred pursuant to Section 7.6(b)(iii) shall be
   adjusted for investment earnings or losses of the trust in which the Union
   Plan assets are held for the period between the Plan Effective Date and the
   actual date of transfer and reduced by the amount of any benefit payments
   actually paid from such plan to Employees and Former Employees during such
   period and a proportionate share of administrative expenses for such period
   if such administrative expenses are properly chargeable (and are actually
   charged) to the Union Plan. Sellers shall estimate such earnings as of the
   actual date of transfer and then within 90 days of the actual date of
   transfer, Sellers shall cause Sellers' Trustee to remit to the Company's
   Trustee or the Buyer shall cause the Buyer's Trustee to remit to Sellers'
   Trustee, as appropriate, an amount equal to the difference between the actual
   rate of earnings for such period and the estimated amount transferred as of
   the actual date of transfer (such difference to be adjusted for investment
   earnings at the State Street Bank short-term rate for the period between the
   actual date of transfer and the date such difference is paid to Sellers'
   Trustee or the Buyer's Trustee). Notwithstanding anything in this Section
   7.6(b) to the contrary, following the Plan Effective Date and until the date
   of the respective transfers of assets to trusts under the Buyer's Pension
   Plan, Sellers shall cause Sellers' Trustee to continue to provide benefits to
   plan participants in accordance with the terms of the Union Plan to the
   extent that such benefits have accrued on or before the Plan Effective Date.
   To the extent that benefits have accrued after the Plan Effective Date,
   following the transfer of assets pursuant to Section 7.6(b)(iii), the Buyer
   shall pay such benefits to plan participants (retroactively, if applicable)
   in accordance with the terms of the Buyer's Pension Plan.

     (v) The assets caused to be transferred pursuant to Section 7.6(b)(iii)
   shall be calculated by Sellers' actuary, and shall be subject to review by
   the Buyer's actuary for the purpose of confirming that the calculation was
   made in accordance with (i) the actuarial assumptions and methods set forth
   in this Section 7.6(b) and (ii) generally accepted actuarial practice. As
   soon as practicable after receiving the notification from Buyer referred to
   in Section 7.6(b)(ii), Sellers shall provide the Buyer with a detailed
   summary of the calculations described in this Section 7.6(b) and any back-up
   data reasonably requested by Buyer. If the Buyer or the Buyer's actuary do
   not notify Metaldyne to the contrary within 60 days after the delivery to
   Buyer of such detailed summary and data, the calculations of Sellers' actuary
   pursuant to this Section 7.6(b) shall be deemed to be final, conclusive and
   binding on the parties. If, however, Buyer notifies Metaldyne in writing
   within such period that it and its actuary believe that the calculations were
   not prepared in accordance with the requirements of this Section 7.6(b) and
   such notice specifies (i) the precise items of the calculations challenged,
   (ii) the basis of the challenge

                                     - 23 -

   and (iii) the amount of the adjustment they propose with respect to each such
   item, the parties will then attempt to resolve their differences with respect
   thereto. If the parties are unable to resolve their dispute within 30 days
   after the date the Buyer notifies Metaldyne of the disputed items, the
   disputed items shall be referred to an international benefits consulting firm
   (the "ACTUARY FIRM") mutually acceptable to Buyer and Sellers. Sellers and
   Buyer shall request that the Actuary Firm resolve such disputes and report to
   Sellers and Buyer upon such remaining disputed items within 45 days after
   such referral. The decision of the Actuary Firm shall be final, conclusive
   and binding on the parties hereto. The fees and expenses of the Actuary Firm
   in conducting this assignment shall be borne equally by Sellers on the one
   hand and Buyer on the other.

     (c) Defined Contribution Plan. As soon as practical after the Closing Date,
   Sellers shall cause the trustee of Sellers' defined contribution plans listed
   on Schedule 7.6(c) hereof ("SELLERS' SAVINGS PLANS") to transfer all of the
   assets and liabilities thereof attributable to Employees and Former Employees
   of the Acquired Business to one or more defined contribution plans maintained
   by Buyer. Unless otherwise agreed by Sellers and Buyer, the assets to be
   transferred shall be cash and promissory notes for loans made to Employees
   and Former Employees of Buyer under the terms of the Sellers' Savings Plans.
   Sellers shall be responsible for making contributions to Sellers' Savings
   Plans for Employees and Former Employees for all periods prior to the
   Effective Time but not thereafter.

     (d) Severance and Other Liability. Buyer shall pay an amount to Sellers
   equal to the sum of (i) the excess of the "accumulated benefit obligation" of
   each of the MascoTech, Inc. Pension Plan and MascoTech, Inc. Master Hourly
   Employees Pension Plan attributable to Employees and Former Employees, over
   the amount of assets of each such plan attributable to Employees and Former
   Employees, all calculated as of the Effective Time, and (ii) the FAS 87
   service cost resulting from Sellers' agreement to credit additional service
   and compensation set forth in Section 7.6(b)(i) hereof (determined using the
   actuarial assumptions and methods utilized by Sellers in determining the
   service cost for such plans). Such "accumulated benefit obligation" for each
   such plan shall be computed using a discount rate of 6.75%, compounded
   annually and the other actuarial assumptions and methods utilized by Sellers
   in determining the "accumulated benefit obligation" of such plans for FAS 87
   purposes as of the Effective Time. The amount of plan assets allocable to the
   Employees and Former Employees shall be determined by multiplying the actual
   fair market value of the assets of each plan at the Effective Time by a
   fraction, the numerator of which is the "accumulated benefit obligation"
   (determined as set forth above) of the applicable plan attributable to the
   Employees and Former Employees (the "BUYER'S ABO"), and the denominator of
   which is the sum of the Buyer's ABO and the "projected benefit obligation"
   (computed using a discount rate of 6.75%, compounded annually and the other
   actuarial assumptions and methods utilized by Seller in determining the
   "projected benefit obligation" of such plans for FAS 87 purposes as of the
   Effective Time) attributable to participants and former participants in the
   plan other than the Employees and Former Employees. The computations shall be
   made by Sellers'

                                     - 24 -

   actuary, and they shall be subject to review in accordance with the procedure
   set forth in Section 7.6(b)(v) above. Following final agreement on the
   calculations described herein, Sellers shall remit to the Buyer or the Buyer
   shall remit to Sellers, as appropriate, an amount equal to the difference
   between the actual amount owed and the estimated amount transferred as of
   Closing Date (such difference to be adjusted for investment earnings at the
   State Street Bank short-term rate for the period between the Closing Date and
   the date such difference is paid to Seller or Buyer).

     (e) Worker's Compensation Claims. The Buyer shall assume liability for all
   suits, claims, proceedings and actions pending as of or commenced after the
   Effective Time resulting from actual or alleged harm or injury to Employees
   or Former Employees regardless of when the incident or accident giving rise
   to such liability occurred or occurs. Buyer shall make all necessary
   arrangements to assume all worker's compensation claim files, whether open or
   closed, as of the Effective Time, and Buyer shall make the necessary
   arrangements for assuming the continued management of such liabilities.

     (f) Welfare Benefit Plans. (i) Coverage for all Transferred Employees and
   Former Employees (the "COVERED EMPLOYEES") and their respective eligible
   dependents under the welfare benefit plans (as defined in Section 3(1) of
   ERISA) maintained by the Sellers or their Affiliates for the benefit of
   Employees prior to the Closing Date (the "SELLER WELFARE PLANS") shall
   terminate effective as of the Effective Time. Subject to the satisfaction of
   any conditions, limitations or waiting periods referred to in subsection (ii)
   below, the welfare benefit plans (as defined in Section 3(1) of ERISA)
   maintained by Buyer or its Affiliates (the "BUYER WELFARE PLANS") shall
   provide coverage and benefits to such Covered Employees (and the eligible
   dependents of such Covered Employees) in substantially the same manner as
   provided by seller prior to the Effective Time. The Seller Welfare Plans
   shall be liable only for claims incurred prior to the Effective Time, and the
   Buyer shall be liable for any claims incurred by Covered Employees (and the
   eligible dependents of such Covered Employees) after the Effective Time. The
   Covered Employees shall be entitled to apply deductibles and out of pocket
   payments expended for covered medical and dental expenses under the Seller
   Welfare Plans in the plan fiscal year ending December 31, 2003, to the
   deductibles and out of pocket maximums under the Buyer Welfare Plans, if any,
   for the plan fiscal year which ends on December 31, 2003. If requested by the
   Buyer, the Sellers shall furnish the Buyer with a schedule setting forth the
   deductibles and out of pocket maximums for each Covered Employee. The Seller
   Welfare Plans shall be liable only for claims incurred prior to or as of the
   Effective Time, and the Sellers shall be liable for any claims incurred by
   Covered Employees (and the eligible dependents of such Covered Employees)
   under the Buyer Welfare Plans after the Effective Time.

     (ii) No pre-existing condition limitations, exclusions or waiting periods
   applicable with respect to life and accident death and dismemberment
   insurance, disability, sickness and accident and medical benefits under the
   Buyer Welfare Plan shall apply to

                                     - 25 -

   the Covered Employees to the extent that such limitations, exclusions or
   waiting periods exceed those in effect under the Seller Welfare Plans as of
   the Effective Time.

     (g) To the extent that Buyer or Sellers are unable to, with reasonably
   diligent effort and at reasonable expense, perform their obligations in the
   manner contemplated by this Section 7.6, Buyer and Sellers shall cooperate in
   order to achieve the most economic transfer reasonably practicable and Buyer
   on the one hand and Sellers on the other agree to indemnify each other for
   any incremental expenses incurred by the other as a result of any
   accommodation by either such party from the respective responsibilities
   assigned to the parties by this Section 7.6.

     SECTION 7.7. INFORMATION; COOPERATION. If after the Closing, in order
properly to prepare documents or reports required to be filed with Governmental
Authorities or financial statements, it is necessary that Buyer or Sellers be
furnished with additional information relating to the Acquired Business and such
information is in possession of any party hereto, such party will use its
reasonable efforts to furnish, or cause to be furnished, such information to the
party requesting information.

     SECTION 7.8. FURTHER ASSURANCES. In case at any time after the Closing Date
any further action is necessary or desirable to fully and effectively transfer
the benefits of the Purchased Assets to Buyer and to fully and effectively
provide for the assumption of the Assumed Liabilities by Buyer or otherwise to
carry out the purposes of this Agreement, the proper officers and directors of
Buyer and Sellers shall execute such further documents (including assignments,
acknowledgments and consents and other instruments of transfer) and shall take
and cause their respective employees and agents to take such further actions as
may be necessary or desirable in order to carry out the intent of this
Agreement.

                                 ARTICLE VIII.

pertaining to the performance of such Alterations. In addition, Tenant shall
indemnify, defend and hold harmless Landlord against liability, loss, cost,
damage, liens and expense imposed on Landlord arising out of the performance of
Alterations by Tenant.

16. SURRENDER. Upon the expiration of this Sublease, or upon the termination of
the Sublease or of the Tenant's right to possession of the Premises, Tenant will
at once surrender and deliver up the Premises, together with all improvements
thereon, only to the extent required under the Prime Lease, to Landlord in the
condition required under the Prime Lease and pursuant to the requirements of the
Prime Lease, including the removal of any alterations made by Landlord or
Tenant, to the extent Prime Landlord requires their removal.

17. REMOVAL OF TENANT'S PROPERTY. Upon the expiration of this Sublease, Tenant
shall remove Tenant's articles of personal property incident to Tenant's
business ("TRADE FIXTURES"); provided, however, that Tenant shall repair any
injury or damage to the Premises which may result from such removal, and shall
restore the Premises to the same condition as prior to the

                                     - 39 -

installation thereof. If Tenant does not remove Tenant's Trade Fixtures from the
Premises prior to the expiration or earlier termination of the Term, Landlord
may, at its option, remove the same (and repair any damage occasioned thereby
and restore the Premises as aforesaid) and dispose thereof or deliver the same
to any other place of business of Tenant, or warehouse the same, and Tenant
shall pay the cost of such removal, repair, restoration, delivery or warehousing
to Landlord on demand, or Landlord may treat said Trade Fixtures as having been
conveyed to Landlord with this Sublease as a bill of sale, without further
payment or credit by Landlord to Tenant.

18. HOLDING OVER. Tenant shall have no right to occupy the Premises or any
portion thereof after the expiration of this Sublease or after termination of
this Sublease or of Tenant's right to possession in consequence of an Event of
Default hereunder. In the event Tenant or any party claiming by, through or
under Tenant holds over, thereafter the tenancy shall be from month to month in
the absence of a written agreement to the contrary, and Tenant shall pay to
Prime Landlord a daily occupancy charge equal to five percent (5%) of the Basic
Rental (as defined in the Prime Lease) for the last lease year (plus all other
charges payable by Tenant under this Sublease) from each day from the expiration
or termination of this Sublease until the date the Premises are delivered in the
condition required herein, and Landlord's right to damages for such illegal
occupancy shall survive

19. ENCUMBERING TITLE. Tenant shall not do any act which shall in any way
encumber the title of Prime Landlord in and to the Premises, nor shall the
interest or estate of Prime Landlord or Landlord be in any way subject to any
claim by way of lien or encumbrance, whether by operation of law, by virtue of
any express or implied contract by Tenant or by reason of any other act or
omission of Tenant. Any claim to, or lien upon the Premises arising from any act
or omission of Tenant shall accrue only against the subleasehold estate of
Tenant and shall be subject and subordinate to the paramount title and rights of
Prime Landlord in and to the Premises and the interest of Landlord in the
Premises leased pursuant to the Prime Lease. Without limiting the generality of
the foregoing, Tenant shall not permit the Premises to become subject to any
mechanic's or other lien, charge or order for the payment of money filed against
Landlord or Prime Landlord as a result of any act or omission of Tenant;
provided, however, that if so permitted under the Prime Lease, Tenant shall have
the right to contest in good faith and with reasonable diligence, the validity
of any such lien or claimed lien; provided further, however, that Tenant shall,
at its own cost and expense, cause the same to be discharged of record or bonded
within thirty (30) days after written notice from Landlord or Prime Landlord to
Tenant of the filing thereof; and Tenant shall indemnify and save and hold
harmless Landlord, and if so required by the Prime Lease, Prime Landlord,
against and from all costs, liabilities, suits, penalties, claims and demands,
including reasonable attorneys' fees, resulting therefrom.

20. INDEMNITY.

A. Tenant agrees to indemnify, forever save and hold Landlord and each of
Landlord's agents, contractors, licensees, employees, managers, members,
directors, officers, partners, trustees and invitees (collectively, the
"INDEMNIFIED PARTIES;" each, an "INDEMNIFIED PARTY") harmless from and against
any and all Losses which any Indemnified Party may suffer or incur

                                     - 40 -

limitation, (i) Tenant's failure to comply with the provisions of this Sublease;

Building (as defined in the Prime Lease); (iv) Tenant's employees nonobservance
or nonperformance or any statute, law, ordinance, rule or regulation; (v) any
negligence or other wrongful act or omission on the part of Tenant or any of its
agents, contractors, licensees, employees, directors, officers, partners,
trustees, successors or assigns or (vii) any accident, injury or damage to any
person or property occurring in, on or about the Premises or any part thereof
during the Term of this Sublease, except to the extent caused by the negligence
or willful misconduct of any Indemnified Party.

B. Landlord agrees to indemnify, forever save and hold Tenant and each of
Tenant's agents, contractors, licensees, employees, managers, members,
directors, officers, partners, trustees and invitees (collectively, the "TENANT
INDEMNIFIED PARTIES;" each, a "TENANT INDEMNIFIED PARTY") harmless from and
against any and all Losses which any Tenant Indemnified Party may suffer or
incur arising out of, (i) Landlord's failure to comply with the provisions of
this Sublease; (ii) Landlord's employees nonobservance or nonperformance of any
statute, law, ordinance, rule or regulation; (iii) any negligence or other
wrongful act or omission on the part of Landlord or any of its agents,
contractors, licensees, employees, directors, officers, partners, trustees,
successors or assigns or (iv) any accident, injury or damage to any person or
property occurring in, on or about the Premises or any part thereof during the
term of this Sublease to the extent caused by the negligence or willful
misconduct of Landlord (with respect to a claim against Tenant).

C. The parties hereto acknowledge and agree that any claim for indemnification
hereunder and the obligations owed to the Indemnified Party or the Tenant
Indemnified Party, as the case may be, shall be subject to the provisions of
Sections 9.2 and 9.3 of the Asset Purchase Agreement.

21. LANDLORD'S RESERVED RIGHTS. Landlord shall have the same access rights as
Prime Landlord under the Prime Lease.

22. DEFAULTS. Tenant agrees that any one or more of the following events shall
be considered Events of Default as said term is used herein:

or judgment or order shall not have been vacated or stayed or set aside within

writing to Tenant; or

H. Tenant shall, by its act or omission to act, cause a default under the Prime
Lease and such default shall not be cured within the time, if any, permitted for
such cure under the Prime Lease; or

I. Tenant shall default in any of the other covenants and agreements herein
contained to be kept, observed and performed by Tenant, and such default shall
continue for thirty (30) days after notice thereof in writing to Tenant, and
Tenant shall not within such 30-day period commence with due diligence and
dispatch the curing of such default or having so commenced, shall thereafter
fail or neglect to prosecute or complete with due diligence and dispatch the
curing of such default.

23. REMEDIES. Upon the occurrence of any one or more Events of Default, Landlord
may exercise any remedy against Tenant which Prime Landlord may exercise for
default by Landlord under the Prime Lease.

24. NOTICES AND CONSENTS. All notices, demands, requests, consents or approvals
which may or are required to be given by either party to the other shall be in
writing and shall be deemed given when received or refused if sent by United
States registered or certified mail, postage prepaid, return receipt requested
or if sent by overnight commercial courier service (a) if to Tenant, addressed
to Tenant at the address specified in Section 1(B) or at such other place as

                                     - 42 -

Tenant may from time to time designate by notice in writing to Landlord or (b)
if for Landlord, addressed to Landlord at the address specified in Section 1(C)
or at such other place as Landlord may from time to time designate by notice in
writing to Tenant. Each party agrees to promptly deliver a copy of each notice,
demand, request, consent or approval from such party to Prime Landlord and
promptly to deliver to the other party a copy of any notice, demand, request,
consent or approval received from Prime Landlord. Such copies shall be delivered
by overnight commercial courier.

25. PROVISIONS REGARDING SUBLEASE. This Sublease and all the rights of parties
hereunder are subject and subordinate to the Prime Lease. Each party agrees that
it will not, by its act or omission to act, cause a default under the Prime
Lease. In furtherance of the foregoing, the parties hereby confirm, each to the
other, that it is not practical in this Sublease agreement to enumerate all of
the rights and obligations of the various parties under the Prime Lease and
specifically to allocate those rights and obligations in this Sublease
agreement. Accordingly, in order to afford to Tenant the benefits of this
Sublease and of those provisions of the Prime Lease which by their nature are
intended to benefit the party in possession of the Premises, and in order to
protect Landlord against a default by Tenant which might cause a default or
event of default by Landlord under the Prime Lease:

A. To the extent Prime Landlord requires payment directly from Landlord and
provided Tenant timely pays all Rent when and as due under this Sublease,
Landlord shall pay, when and as due, any and all base rent, additional rent and
other charges payable by Landlord to Prime Landlord to the extent required under
the Prime Lease.

B. Landlord shall promptly provide Tenant with copies of all notices received by
Landlord under the Prime Lease from Prime Landlord or its mortgagee.

C. Except as otherwise expressly provided for herein, during the Term hereof
Tenant shall perform all affirmative covenants of Landlord under the Prime Lease
and shall refrain from performing any act which is prohibited by the negative
covenants of the Prime Lease.

D. Landlord shall not agree to any amendment to the Prime Lease unless Landlord
shall first obtain Tenant's prior written approval thereof, which approval shall
not be unreasonably withheld, conditioned or delayed.

E. Except as otherwise provided herein, Tenant shall be entitled to the rights
of Landlord, as tenant under the Prime Lease. Without limiting the generality of
the foregoing, Landlord hereby grants to Tenant the right to receive all of the
services and benefits with respect to the Premises which are to be provided by
Prime Landlord under the Prime Lease. Landlord shall have no duty to perform any
obligations of Prime Landlord which are, by their nature, the obligation of an
owner or manager of real property. For example, Landlord shall not be required
to provide the services or repairs, if any, which the Prime Landlord is required
to provide under the Prime Lease. Landlord shall have no responsibility for or
be liable to Tenant for any default, failure or delay on the part of Prime
Landlord in the performance or observance by Prime Landlord of any

                                     - 43 -

of its obligations under the Prime Lease, nor shall such default by Prime
Landlord affect this Sublease or waive or defer the performance of any of
Tenant's obligations hereunder except to the extent that such default by Prime
Landlord excuses performance by Landlord, under the Prime Lease. Notwithstanding
the foregoing, the parties contemplate that Prime Landlord shall, in fact,
provide the services and benefits and perform its obligations under the Prime
Lease and in the event of any default or failure of such provision or
performance by Prime Landlord, Landlord agrees that it will, upon notice from
Tenant, make demand upon, deliver notices to and request consents or approvals
from Prime Landlord to provide such services or benefits and perform its
obligations under the Prime Lease and, provided that Tenant specifically agrees
to pay all reasonable costs and expenses of Landlord and provides Landlord with
security reasonably satisfactory to Landlord to pay such costs and expenses,
Landlord will take appropriate legal action to enforce the Prime Lease.

F. Tenant shall have the right to exercise all renewal rights granted to
Landlord under the Prime Lease.

G. Landlord shall cooperate with Tenant to cause Prime Landlord to provide
services required by Tenant in addition to those otherwise required to be
provided by Prime Landlord under the Prime Lease. Tenant shall pay Prime
Landlord's charge for such services promptly after having been billed therefor
by Prime Landlord or by Landlord.

26. SECURITY DEPOSIT.

A. To secure the faithful performance by Tenant of all the covenants, conditions
and agreements in this Sublease set forth and contained on the part of Tenant to
be fulfilled, kept, observed and performed including, but not by way of
limitation, such covenants and agreements in this Sublease which become
applicable upon the termination of the same by re-entry or otherwise, Tenant
shall deposit with Landlord the Security Deposit as specified in Section 1(N) on
the understanding that: (a) the Security Deposit or any portion thereof not
previously applied, or from time to time, such one or more portions thereof, may
be applied to the curing of any default that may then exist, without prejudice
to any other remedy or remedies which Landlord may have on account thereof, and
upon such application Tenant shall pay Landlord on demand the amount so applied
which shall be added to the Security Deposit so the same may be restored to its
original amount; (b) should the Prime Lease be assigned by Landlord, the
Security Deposit or any portion thereof not previously applied may be turned
over to Landlord's assignee and if the same be turned over as aforesaid, Tenant
hereby releases Landlord from any and all liability with respect to the Security
Deposit and/or its application or return; (c) if permitted by law, Landlord or
its successor shall not be obligated to hold the Security Deposit as a separate
fund, but on the contrary may commingle the same with its other funds; (d) if
Tenant shall faithfully fulfill, keep, perform and observe all of the covenants,
conditions and agreements in this Sublease set forth and contained on the part
of Tenant to be fulfilled, kept, performed and observed, the sum deposited or
the portion thereof not previously applied, shall be returned to Tenant without
interest no later than thirty (30) days after the expiration of the Term of this
Sublease or any renewal or extension thereof, provided Tenant has vacated the
Premises and surrendered possession thereof to

                                     - 44 -

Landlord at the expiration of the Term or any extension or renewal thereof as
provided herein; (e) in the event that Landlord terminates this Sublease or
Tenant's right to possession by reason of an Event of Default by Tenant,
Landlord may apply the Security Deposit against damages suffered to the date of
such termination and/or may retain the Security Deposit to apply against such
damages as may be suffered or shall accrue thereafter by reason of Tenant's
default; and (f) in the event any bankruptcy, insolvency, reorganization or
other creditor-debtor proceedings shall be instituted by or against Tenant, or
its successors or assigns, the Security Deposit shall be deemed to be applied
first to the payment of any Rent due Landlord for all periods prior to the
institution of such proceedings, and the balance, if any, of the Security
Deposit may be retained or paid to Landlord in partial liquidation of Landlord's
damages.

B. Notwithstanding the above, Tenant shall have the right to post a letter of
credit in place of the cash security deposit required in Section 26(A) of this
Sublease in the same manner as Landlord has the right to post a letter of credit
rather than cash security pursuant to Section 39(c) of the Prime Lease. In
addition, Tenant shall have the obligation to post a letter of credit as
additional security for this Sublease in the same manner as Landlord is
obligated to post additional security for the Prime Lease pursuant to Section
39(b) of the Prime Lease (except that the test shall be the Moody's and/or
Standard & Poors rating of TriMas Company, LLC, the guarantor, rather than
Landlord).

27. PRIME LANDLORD'S CONSENT. The parties acknowledge that, pursuant to Section
13(d) of the Prime Lease, Prime Landlord's consent to this Sublease is not
required.

28. BROKERAGE. Each party warrants to the other that it has had no dealings with
any broker or agent in connection with this Sublease.

29. FORCE MAJEURE. Neither Landlord nor Tenant shall be deemed in default with
respect to any of the terms, covenants and conditions of this Sublease if such
parties failure to timely perform same is due in whole or in part to any strike,
lockout, labor trouble (whether legal or illegal), civil disorder, failure of
power, restrictive governmental laws and regulations, riots, insurrections, war,
shortages, accidents, casualties, acts of God, or any other cause beyond the
reasonable control of such party.

30. TRIMAS GUARANTEE. As a condition to Landlord entering into the Sublease,
Tenant shall obtain the unconditional guarantee of this Sublease by TriMas
Company LLC in the form attached hereto as Annex 2.

31. CERTIFICATES. Each party shall, without charge, at any time and from time to
time hereafter, within ten (10) days after written request of the other party,
certify to the best of its knowledge by written instrument duly executed and
acknowledged to any mortgagee or purchaser, or proposed mortgagee or proposed
purchaser, of any other person, firm or corporation specified in such request:
(a) as to whether this Sublease has been supplemented or amended, and if so, the
substance and manner of such supplement or amendment; (b) as to the validity and
force and effect of this Sublease, in accordance with its tenor as then
continued; (c) as to the ex-

                                     - 45 -

istence of any default thereunder; (d) as to the existence of any offsets,
counterclaims or defenses hereto on the part of such other party; (e) as to the
commencement and expiration dates of the Term hereof and (f) as to any other
matters as may reasonably be so requested. Any such certificate may be relied
upon by the party requesting it and any other person, firm or corporation to
whom the same may be exhibited or delivered, and the contents of such
certificate shall be binding on the party executing same.

32. MISCELLANEOUS. The laws of the State of Michigan shall govern the validity,
performance, and enforcement of this Sublease. The invalidity or
unenforceability of any provision of this Sublease shall not affect or impair
any other provision of this Sublease or the Sublease itself. The submission of
this document for examination does not constitute an offer to lease, or a
reservation of or option for the Premises, and becomes effective only upon
execution and delivery thereof by Landlord and Tenant. All negotiations,
considerations, representations, and understandings between the parties are
incorporated herein and may be modified or altered only by agreement in writing
between the parties. This Sublease shall not be recorded. A memorandum of lease
describing the property, giving the commencement date and term of this Sublease
and renewal rights, and referring to this Sublease, may be executed and may be
recorded by either party. The agreements, terms, covenants, and conditions
herein shall bind and inure to the benefit of Landlord and Tenant and their
respective successors and, except as otherwise provided herein, their assigns.

The parties have executed this Sublease the day and year first above written.

                                    GUARANTY

     The undersigned, TRIMAS COMPANY LLC, a Delaware limited liability company
("GUARANTOR"), whose address is 39400 Woodward Avenue, Suite 130, Bloomfield
Hills, Michigan 48304, in consideration of the leasing of the leased Premises
described in that certain sublease (the "SUBLEASE") of even date herewith
between METALDYNE COMPANY LLC ("LANDLORD") and _________________________________
("TENANT"), does hereby covenant and agree as follows:

A.   The undersigned does hereby guarantee the full, faithful and timely payment
     and performance by Tenant of all of the payments, covenants and other
     obligations of Tenant under or pursuant to the Sublease. If Tenant shall
     default at any time in the payment of any rent or any other sums, costs or
     charges whatsoever, or in the performance of any of the other covenants and
     obligations of Tenant, under or pursuant to the Sublease, then the
     undersigned, at its expense, shall on demand of Landlord fully and promptly
     pay all rent, sums, costs and charges to be paid by Tenant, and perform all
     of the other covenants and obligations to be performed by Tenant, under or
     pursuant to the Sublease and, in addition, shall, on Landlord's demand, pay
     to Landlord any and all sums due to Landlord, including all interest on
     past due obligations of Tenant and costs advanced by Landlord, that may
     arise in consequence of Tenant's default.

B.   A separate action or actions may, at Landlord's option, be brought and
     prosecuted against the undersigned, whether or not any action is first or
     subsequently brought against Tenant, or whether or not Tenant is joined in
     any such action, and the undersigned may be joined in any action or
     proceeding commenced by Landlord against Tenant arising out of, in
     connection with or based upon the Sublease.

C.   Subject to the provisions of the immediately following paragraph, this
     Guaranty shall remain and continue in full force and effect and shall not
     be discharged in whole or in part notwithstanding (whether prior or
     subsequent to the execution hereof) any alteration, renewal, extension,
     modification, amendment or assignment of, or subletting, concession,
     franchising, licensing or permitting under, the Sublease. The undersigned
     agrees that the liability of the undersigned hereunder shall be based upon
     the obligations of Tenant set forth in the Sublease as the same may be
     altered, renewed, extended, modified, amended or assigned.

D.   This Guaranty shall remain in full force and effect notwithstanding the
     institution by or against Tenant, of bankruptcy, reorganization,
     readjustment, receivership or

     insolvency proceedings of any nature, or the disaffirmance of the Sublease
     in any such proceedings or otherwise.

E.   Neuter terms should also refer, where applicable, to the feminine gender
     and the masculine gender; the singular reference shall also include the
     plural of any word if the context so requires.

F.   This Guaranty shall be applicable to and binding upon the heirs, executors,
     administrators, representatives, successors and assigns of Landlord, Tenant
     and the undersigned.

G.   The execution of this Guaranty prior to execution of the Sublease shall not
     invalidate this Guaranty or lessen the obligations of Guarantor hereunder.

H.   This Guaranty is made pursuant to, and shall be interpreted and applied in
     accordance with, the laws of the State of Michigan. Any legal action or
     proceeding with respect to this Guaranty may be brought in the Courts of
     the State of Michigan, or the District Court of the United States of
     America for the Eastern District of Michigan, and, by execution and
     delivery of this Guaranty, the Guarantor hereby irrevocably accepts for
     itself the jurisdiction of the aforesaid courts. The Guarantor hereby
