affecting the Premises, or of a taking of all or a part of the Building or
Premises under the power of eminent domain, Landlord shall not exercise any
right which may have the effect of terminating the Prime Lease without first
obtaining the prior written consent of Tenant. In the event Landlord is
entitled, under the Prime Lease, to a rent abatement as a result of a fire or
other casualty or as a result of a taking under the power of eminent domain,
then Tenant shall be entitled to such rent abatement. If the Prime Lease imposes
on Landlord the obligation to repair or restore leasehold improvements or
alterations, Tenant shall be responsible for the repair or restoration of such
leasehold improvements or alterations.

15. ALTERATIONS. Tenant may make any alterations in or additions or improvements
to the Premises ("ALTERATIONS"), but only after obtaining Landlord's and Prime
Landlord's written consent if and to the extent such consent is required to be
obtained by Landlord under the Prime Lease. Tenant shall make Alterations in
compliance with all of the covenants of Landlord contained in the Prime Lease
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 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



                                      -4-



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.

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 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



                                     - 7 -





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 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

                                    GUARANTY


                  The undersigned, TRIMAS COMPANY LLC, a Delaware limited

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

         irrevocably accepts for itself the jurisdiction of the aforesaid
         courts. The Guarantor hereby irrevocably consents to the service of

         proceeding by the mailing of copies thereof by registered mail, return
         receipt requested, to the Guarantor at the addresses provided herein,
         such service to become effective 30 days after such mailing, or such
         earlier time as may be provided by applicable law. The Guarantor hereby
         irrevocably waives any objection which it may now or hereafter have to
         the laying of venue of any of the aforesaid actions or proceedings
         arising out of or in connection with this Guaranty brought in the
         courts referred to above and hereby further irrevocably waives and
         agrees not to plead or claim in any such court that such action or
         proceeding brought in any such court has been brought in an
         inconvenient forum.

         Tenant's address is 39400 Woodward Avenue, Suite 130, Bloomfield Hills,

         IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO
         THIS GUARANTY.
