its Chief Financial Officer, Company enters into this Agreement with Executive
to set out the terms and conditions that will apply to Executive's employment
with Company. Executive is willing to accept such employment and assignment and
to perform services on the terms and conditions hereinafter set forth. It is
therefore hereby agreed by and between the parties as follows:

         SECTION 1 - EMPLOYMENT.

          (a)  Company employs Executive as its Chief Financial Officer. In this
               capacity, Executive shall report to the President and Chief
               Executive Officer ("CEO"). Executive accepts employment in
               accordance with this Agreement and agrees to devote his full
               business time and efforts to the performance of his duties and
               responsibilities hereunder.

          (b)  Nothing in this Agreement shall preclude Executive from engaging
               in charitable and community affairs, from managing any passive
               investment (i.e., an investment with respect to which Executive
               is in no way involved with the management or operation of the
               entity in which Executive has invested) made by him in publicly
               traded equity securities or other property (provided that no such
               investment may exceed five percent (5%) of the equity of any
               entity, without the prior approval of the Board of Directors of
               Company (the "Board")), or from serving, subject to the prior
               approval of the Board, as a member of boards of directors or as a
               trustee of any other corporation, association or entity, to the
               extent that any of the above activities do not conflict with any
               provision of this Agreement.

         SECTION 2 - TERM OF EMPLOYMENT. Executive's term of employment under
this Agreement ("Term of Employment") shall commence on the Effective Date and,
subject to the terms hereof, shall terminate on the earlier of: December 31,
2004 ("Initial Period"); or the date that either party terminates Executive's
employment under this Agreement; provided that subsequent to the Initial Period,
the Term of Employment shall automatically renew each January 1 for one year
("Renewal Period"), unless Company delivers to Executive or Executive delivers
to Company written notice at least thirty (30) days in advance of the expiration
of the Initial Period or any Renewal Period, that the Term of Employment shall
not be extended, in which case the Term of Employment shall end at the end of
the Year in which such notice was delivered and shall not be further extended
except by written agreement of Company and Executive. The expiration of the Term
of Employment under this Agreement shall not be a termination of this Agreement
to the extent that other provisions of this Agreement by their terms survive the
Term of Employment.

                                       2



                                                                    SECTION 6(a)


          (a)  Termination Without Cause or for Good Reason. If Executive's
               employment is terminated during the Term of Employment by Company
               for any reason other than Cause (as defined in Section 6(c)
               hereof), Disability (as defined in Section 6(e) hereof) or death,
               or if Executive's employment is terminated by Executive for Good
               Reason (as defined in Section 6(a)(2) hereof), then Company shall
               pay Executive the Severance Package. Any termination of
               employment that results from a notice of nonrenewal given in
               accordance with Section 2 of this Agreement shall not be a
               termination under this Section 6(a) but shall instead be a
               termination under Section 6(b) below. Likewise, a termination by
               Executive without Good Reason shall be a termination under
               Section 6(b) below and not a termination under this Section 6(a).

               (1)  For purposes of this Agreement, "Severance Package" shall
                    mean:

                    (A)  Base Salary continuation for twenty-four (24) months at
                         Executive's annual Base Salary rate in effect on the
                         date of termination, subject to all applicable federal,
                         state and local withholding and reporting requirements.
                         These salary continuation payments shall be paid in
                         accordance with usual Company payroll practices;

                    (B)  A bonus equal to two hundred percent (200%) of the
                         target bonus opportunity under AVCP, payable in equal
                         installments over the twenty-four (24) month period
                         described in Section 6(a)(1)(A) above, subject to the
                         same withholding and reporting requirements. In
                         addition, Executive shall receive the bonus for the
                         most recently completed bonus term if a bonus has been
                         declared for such term but not paid, and a pro rata
                         bonus for the year of termination through the date of
                         termination calculated at one hundred percent (100%) of
                         the bonus opportunity for target performance for that
                         term, multiplied by a fraction the numerator of which
                         is the number of days that Executive was employed
                         during such bonus term and the denominator of which is
                         365. The prorated bonus for the final year shall be
                         paid in a single sum within ten (10) days of the
                         termination of Executive's employment with Company. Any
                         unpaid bonus shall be paid in accordance with customary
                         practices for payment of bonuses under AVCP; and

                    (C)  Continuation of benefits under any life, group medical,
                         and dental insurance benefits substantially similar to
                         those which Executive was receiving immediately prior
                         to termination of employment until the earlier of:

                                       3




                                                           SECTION 6(a)(1)(C)(i)


                         (i)  the end of the twenty-four (24) month period
                              following Executive's termination of employment,
                              or

                         (ii) the date on which Executive becomes eligible to
                              receive any benefits under any plan or program of
                              any other employer.

                         The continuing coverage provided under this Section
                         6(a)(1)(C) is subject to Executive's eligibility to
                         participate in such plans and all other terms and
                         conditions of such plans, including without limitation,
                         any employee contribution requirements and Company's
                         ability to modify or terminate such plans or coverages.
                         Company may satisfy this obligation in whole or in part
                         by paying the premium otherwise payable by Executive
                         for continuing coverage under Section 601 et seq. of
                         the Employee Retirement Income Security Act of 1974, as
                         it may be amended or replaced from time to time. If
                         Executive is not eligible for continued coverage under
                         one of the Company-provided benefit plans noted in this
                         paragraph (C) that he was participating in during his
                         employment, Company shall pay Executive the cash
                         equivalent of the insurance cost for the duration of
                         the applicable period at the rate of the Company's cost
                         of coverage for Executive's benefits as of the date of
                         termination. Any obligation to pay the cash equivalent
                         of such cost under this item may be settled, at
                         Company's discretion, by a lump-sum payment of any
                         remaining premiums.

               (2)  For purposes of this Agreement, a termination of employment
                    by Executive for "Good Reason" shall be a termination by
                    Executive following the occurrence of any of the following
                    events unless Company has cured as provided below:

                    (A)  A material and permanent diminution in Executive's
                         duties or responsibilities;

                    (B)  A material reduction in the aggregate value of Base
                         Salary and bonus opportunity; or

                    (C)  A permanent reassignment of Executive to another
                         primary office, or a relocation of the Company office
                         that is Executive's primary office, unless Executive's
                         primary office following such reassignment or
                         relocation is within thirty-five (35) miles of
                         Executive's primary office before the reassignment or
                         relocation or Executive's permanent residence on the
                         date of the reassignment or relocation.



                                       4



                                                              SECTION 6(a)(2)(C)


                         Executive must notify Company of any event constituting
                         Good Reason within one hundred twenty (120) days after
                         Executive becomes aware of such event or such event
                         shall not constitute Good Reason for purposes of this
                         Agreement provided that Company shall have fifteen (15)
                         days from the date of such notice to cure the Good
                         Reason event. Executive cannot terminate his employment
                         for Good Reason if Cause exists at the time of such
                         termination. A termination by Executive following cure
                         shall not be a termination for Good Reason. A failure
                         of Executive to notify Company after the first
                         occurrence of an event constituting Good Reason shall
                         not preclude any subsequent occurrences of such event
                         (or similar event) from constituting Good Reason.


          (b)  Voluntary Termination by Executive; Expiration of Employment
               Term. If Executive terminates his employment with Company without
               Good Reason, or if the Employment Term expires following notice
               of nonrenewal by either party under Section 2, then Company shall
               pay Executive his accrued unpaid Base Salary through the date of
               termination and the AVCP award for the most recently completed
               year if an award has been declared for such year but not paid.
               The accrued unpaid Base Salary amounts payable under this Section
               6(b) shall be payable in a lump sum within ten (10) days of
               termination of employment. Any accrued unpaid bonus amounts
               payable under this Section 6(b) shall be payable in accordance
               with customary practices for payment of bonuses under AVCP. No
               prorated bonus for the year of termination shall be paid. Any
               other benefits under other plans and programs of Company in which
               Executive is participating at the time of Executive's termination
               of employment shall be paid, distributed, settled, or shall
               expire in accordance with their terms, and Company shall have no
               further obligations hereunder with respect to Executive following
               the date of termination of employment.

          (c)  Termination for Cause. If Executive's employment is terminated
               for Cause, Company shall pay Executive his accrued but unpaid
               Base Salary through the date of the termination of employment,
               and no further payments or benefits shall be owed. The accrued
               unpaid Base Salary amounts payable under this Section 6(c) shall
               be payable in a lump sum within ten (10) days of termination of
               employment. As used herein, the term "Cause" shall be limited to:

               (1)  Executive's conviction of or plea of guilty or nolo
                    contendere to a crime constituting a felony under the laws
                    of the United States or any state thereof or any other
                    jurisdiction in which Company conducts business;

               (2)  Executive's willful misconduct in the performance of his
                    duties to Company;

               (3)  Executive's willful and continued failure to follow the
                    instructions of Company's Board or the CEO; or


                                       5



                                                                 SECTION 6(c)(4)


               (4)  Executive's willful and/or continued neglect of duties
                    (other than any such neglect resulting from incapacity of
                    Executive due to physical or mental illness);

               provided, however, that Cause shall arise under items (3) or (4)
               only following ten (10) days written notice thereof from Company
               which specifically identifies such failure or neglect and the
               continuance of such failure or neglect during such notice period.
               Any failure by Company to notify Executive after the first
               occurrence of an event constituting Cause shall not preclude any
               subsequent occurrences of such event (or a similar event) from
               constituting Cause.

          (d)  Termination Following a Change of Control. In the event
               Executive's employment with Company terminates by reason of a
               Qualifying Termination (as defined below) within three (3) years
               after a Change of Control of Company (as defined below), then, in
               lieu of the Severance Package, and subject to the limitations
               described in Section 7 below, the Company shall provide Executive
               the following termination benefits:

               (1)  Termination Payments. Company shall pay Executive:

                    (A)  A single sum payment equal to two hundred and fifty
                         percent (250%) of Executive's annual Base Salary rate
                         in effect on the date of termination, subject to all
                         applicable federal, state and local withholding and
                         reporting requirements. This single-sum payment shall
                         be paid within ten (10) days of termination of
                         employment;

                    (B)  A bonus equal to two hundred and fifty percent (250%)
                         of the target bonus opportunity under AVCP. In
                         addition, Executive shall receive the bonus for the
                         most recently completed bonus term if a bonus has been
                         declared for such term but not paid, and a pro rata
                         bonus for the year of termination through the date of
                         termination calculated at one hundred percent (100%) of
                         the bonus opportunity for target performance for that
                         term, multiplied by a fraction the numerator of which
                         is the number of days that Executive was employed
                         during such bonus term and the denominator of which is
                         365. The prorated bonus for the final year shall be
                         paid as a single sum within ten (10) days of
                         termination of employment. Any unpaid bonus shall be
                         paid in accordance with customary practices for payment
                         of bonuses under AVCP.

                         All payments under this Section 6(d), however, are
                         subject to the timing rules, calculations and
                         adjustments described in Sections 7 and 8.



                                       6



                                                                 SECTION 6(d)(2)


               (2)  Benefits Continuation. Executive shall continue to receive
                    life, group medical and dental insurance benefits
                    substantially similar to those which Executive was receiving
                    immediately prior to the Qualifying Termination until the
                    earlier of:

                    (A)  the end of the thirty (30) month period following
                         Executive's termination of employment, or

                    (B)  the date on which Executive becomes eligible to receive
                         any benefits under any plan or program of any other
                         employer.

                    The continuing coverage provided under this Section 6(d)(2)
                    is subject to Executive's eligibility to participate in such
                    plans and all other terms and conditions of such plans,
                    including without limitation, any employee contribution
                    requirements and Company's ability to modify or terminate
                    such plans or coverages. Company may satisfy this obligation
                    in whole or in part by paying the premium otherwise payable
                    by Executive for continuing coverage under Section 601 et
                    seq. of the Employee Retirement Income Security Act of 1974,
                    as it may be amended or replaced from time to time. If
                    Executive is not eligible for continued coverage under one
                    of the Company-provided benefit plans noted in this
                    paragraph (2) that he was participating in during his
                    employment, Company shall pay Executive the cash equivalent
                    of the insurance cost for the duration of the applicable
                    period at the rate of the Company's cost of coverage for
                    Executive's benefits as of the date of termination. Any
                    obligation to pay the cash equivalent of such cost of
                    coverage under this item may be settled, at Company's
                    discretion, by a lump-sum payment of any remaining premiums.

               (3)  Qualifying Termination. For purposes of this Agreement, the
                    term "Qualifying Termination" means a termination of
                    Executive's employment with the Company for any reason other
                    than:

                    (A)  death;

                    (B)  Disability, as defined herein;

                    (C)  Cause, as defined herein; or

                    (D)  A termination by Executive without Good Reason, as
                         defined herein.

               (4)  Change of Control Defined. For purposes of this Agreement, a
                    "Change of Control" means the first of the following events
                    to occur following the date hereof:



                                       7



                                                              SECTION 6(d)(4)(A)

                         related transactions (i) of eighty percent (80%) or
                         more of the consolidated assets of the Company and its
                         subsidiaries, or (ii) of seventy-five percent (75%) or
                         more (appropriately adjusted for stock splits,
                         combinations, subdivisions, stock dividends and similar
                         events) of the Capital Stock (as defined below) of the

                         (the "Stock Purchase Agreement"), in either case to any

                         Act") or any similar successor provision, and the
                         rules, regulations and interpretations promulgated
                         thereunder) other than an affiliate of Heartland
                         Industrial Partners, L.P., whether by way of any
                         merger, consolidation or other business combination or
                         purchase of beneficial ownership (within the meaning
                         under Rule 13d-3 of the 1934 Act) or otherwise, but not
                         including (x) sales or transfers which are effected in
                         order to comply with the preemptive rights provisions

                         Purchase Agreement, or (y) sales or transfers which are
                         effected within one year after the date of closing

                         of not greater than $20 plus any interest charged
                         (appropriately adjusted for stock splits, combinations,
                         subdivisions, stock dividends and similar events); or

                    (B)  the date on which the individuals who constitute the
                         Company's Board of Directors on the date of this
                         Agreement, and any new members of the Company's Board
                         of Directors who are hereafter designated by the
                         Heartland Entities (as defined below) cease, for any
                         reason, to constitute at least a majority of the
                         members of the Board of Directors.

               "Capital Stock" means, with respect to any person, any and all
               shares, interests, participations, rights in or other equivalents
               (however designated) of such person's capital stock, and any

                                       8



                                                                    SECTION 6(e)


          (e)  Disability. In the event that Executive is unable to perform his
               duties under this Agreement on account of a disability which
               continues for one hundred eighty (180) consecutive days or more,
               or for an aggregate of one hundred eighty (180) days in any
               period of twelve (12) months, Company may, in its discretion,
               terminate Executive's employment hereunder. Company's obligation
               to make payments under this Agreement shall, except for earned
               but unpaid Base Salary and AVCP awards, cease on the first to
               occur of (i) the date that is six (6) months after such
               termination or (ii) the date Executive becomes entitled to
               benefits under a Company-provided long-term disability program.
               For purposes of this Agreement, "Disability" shall be defined by
               the terms of Company's long-term disability policy, or, in the
               absence of such policy, as a physical or mental disability that
               prevents Executive from performing substantially all of his
               duties under this Agreement and which is expected to be
               permanent. Company may only terminate Executive on account of
               Disability after giving due consideration to whether reasonable
               accommodations can be made under which Executive is able to
               fulfill his duties under this Agreement. The commencement date
               and expected duration of any physical or mental condition that
               prevents Executive from performing his duties hereunder shall be
               determined by a medical doctor selected by Company. Company may,
               in its discretion, require written confirmation from a physician
               of Disability during any extended absence.

          (f)  Death. In the event of Executive's death during the Term of
               Employment, all obligations of Company to make any further
               payments, other than an obligation to pay any accrued but unpaid
               Base Salary to the date of death and any accrued but unpaid
               bonuses under AVCP to the date of death, shall terminate upon
               Executive's death.

          (g)  No Duplication of Benefits. Notwithstanding any provision of this
               Agreement to the contrary, if Executive's employment is
               terminated for any reason, in no event shall Executive be
               eligible for payments under more than one subsection of this
               Section 6.

          (h)  Payments Not Compensation. Any participation by Executive in, and
               any terminating distributions and vested rights under,
               Company-sponsored retirement or savings plans, regardless of
               whether such plans are qualified or nonqualified for tax
               purposes, shall be governed by the terms of those respective
               plans. For purposes of determining benefits and the amounts to be
               paid to Executive under such plans, any salary continuation or
               severance benefits other than salary or bonus accrued before
               termination shall not be compensation for purposes of accruing
               additional benefits under such plans.

          (i)  Executive's Duty to Provide Materials. Upon the termination of
               the Term of Employment for any reason, Executive or his estate
               shall surrender to Company all correspondence, letters, files,
               contracts, mailing lists, customer lists, advertising material,
               ledgers, supplies, equipment, checks, and all other materials and
               records of


                                       9



                                                                 SECTION 7(b)(3)


               any kind that are the property of Company or any of its
               subsidiaries or affiliates, that may be in Executive's possession
               or under his control, including all copies of any of the
               foregoing.


         SECTION 7 - CAP ON PAYMENTS.

          (a)  General Rules. The Internal Revenue Code (the "Code") may place
               significant tax burdens on Executive and Company if the total
               payments made to Executive due to a Change of Control exceed
               prescribed limits. For example, if Executive's "Base Period
               Income" (as defined below) is $100,000, Executive's limit or
               "Cap" is $299,999. If Executive's "Total Payments" exceed the Cap
               by even $1.00, Executive is subject to an excise tax under
               Section 4999 of the Code of 20% of all amounts paid to Executive
               in excess of $100,000. In other words, if Executive's Cap is
               $299,999, Executive will not be subject to an excise tax if
               Executive receives exactly $299,999. If Executive receives
               $300,000, Executive will be subject to an excise tax of $40,000
               (20% of $200,000). In order to avoid this excise tax and the
               related adverse tax consequences for Company, by signing this
               Agreement, Executive will be agreeing that, subject to the
               exception noted below, the present value of Executive's Total
               Payments will not exceed an amount equal to Executive's Cap.

          (b)  Special Definitions. For purposes of this Section, the following
               specialized terms will have the following meanings:

               (1)  "Base Period Income". "Base Period Income" is an amount
                    equal to Executive's "annualized includable compensation"
                    for the "base period" as defined in Sections 280G(d)(1) and
                    (2) of the Code and the regulations adopted thereunder.
                    Generally, Executive's "annualized includable compensation"
                    is the average of Executive's annual taxable income from
                    Company for the "base period," which is the five calendar
                    years prior to the year in which the Change of Control
                    occurs. These concepts are complicated and technical and all
                    of the rules set forth in the applicable regulations apply
                    for purposes of this Agreement.

               (2)  "Cap" or "280G Cap". "Cap" or "280G Cap" shall mean an
                    amount equal to 2.99 times Executive's "Base Period Income."
                    This is the maximum amount which Executive may receive
                    without becoming subject to the excise tax imposed by
                    Section 4999 of the Code or which Company may pay without
                    loss of deduction under Section 280G of the Code.

               (3)  "Total Payments". The "Total Payments" include any "payments
                    in the nature of compensation" (as defined in Section 280G
                    of the Code and the


                                       10


                    regulations adopted thereunder), made pursuant to this
                    Agreement or otherwise, to or for Executive's benefit, the
                    receipt of which is contingent on a Change of Control and to
                    which Section 280G of the Code applies.

          (c)  Calculating the Cap and Adjusting Payments. If Company believes
               that these rules will result in a reduction of the payments to
               which Executive is entitled under this Agreement, it will so
               notify Executive as soon as possible. Company will then, at its
               expense, retain a "Consultant" (which shall be a law firm, a
               certified public accounting firm, and/or a firm of recognized
               executive compensation consultants) to provide an opinion or
               opinions concerning whether Executive's Total Payments exceed the
               limit discussed above. Company will select the Consultant. At a
               minimum, the opinions required by this Section must set forth the
               amount of Executive's Base Period Income, the present value of
               the Total Payments and the amount and present value of any excess
               parachute payments. If the opinions state that there would be an
               excess parachute payment, Executive's payments under this
               Agreement will be reduced to the extent necessary to eliminate
               the excess. Executive will be allowed to choose the payment that
               should be reduced or eliminated, but the payment Executive
               chooses to reduce or eliminate must be a payment determined by
               such Consultant to be includable in Total Payments. Executive's
               decision shall be in writing and delivered to Company within
               thirty (30) days of Executive's receipt of such opinions. If
               Executive fails to so notify Company, Company will decide which
               payments to reduce or eliminate. If the Consultant selected to
               provide the opinions referred to above so requests in connection
               with the opinion required by this Section, a firm of recognized
               executive compensation consultants selected by Company shall
               provide an opinion, upon which such Consultant may rely, as to
               the reasonableness of any item of compensation as reasonable
               compensation for services rendered before or after the Change of
               Control. If Company believes that Executive's Total Payments will
               exceed the limitations of this Section, it will nonetheless make
               payments to Executive, at the times stated above, in the maximum
               amount that it believes may be paid without exceeding such
               limitations. The balance, if any, will then be paid after the
               opinions called for above have been received. If the amount paid
               to Executive by Company is ultimately determined, pursuant to the
               opinion referred to above or by the Internal Revenue Service, to
               have exceeded the limitation of this Section, the excess will be
               treated as a loan to Executive by Company and shall be repayable
               on the ninetieth (90th) day following demand by Company, together
               with interest at the lowest "applicable federal rate" provided in
               Section 1274(d) of the Code. If it is ultimately determined,
               pursuant to the opinion referred to above or by the Internal
               Revenue Service, that a greater payment should have been made to
               Executive, Company shall pay Executive the amount of the
               deficiency, together with interest thereon from the date such
               amount should have been paid to the date of such payment, at the
               rate set forth above, so that Executive will have received or be
               entitled to receive the maximum amount to which Executive is
               entitled under this Agreement.


                                       11



                                                                    SECTION 7(d)

          (d)  Effect of Repeal. In the event that the provisions of Sections
               280G and 4999 of the Code are repealed without succession, this
               Section shall be of no further force or effect.

          (e)  Exception. The Consultant selected pursuant to Section 7(c) will
               calculate Executive's "Uncapped Benefit" and Executive's "Capped
               Benefit." The limitations of Section 7(a) will not apply to
               Executive if Executive's Uncapped Benefit is at least one hundred
               and five percent (105%) of Executive's Capped Benefit. For this
               purpose, Executive's "Uncapped Benefit" is the amount to which
               Executive would be entitled pursuant to Section 6(d), without
               regard to the limitations of Section 7(a). Executive's "Capped
               Benefit" is the amount to which Executive would be entitled
               pursuant to Section 6(d) after the application of the limitations
               of Section 7(a).


         SECTION 8 - TAX GROSS-UP.

          (a)  Gross-Up Payment. If the Cap imposed by Section 7(a) does not
               apply to Executive because of the exception provided by Section
               7(e), Company will provide Executive with a "Gross-Up Payment" if
               an excise tax is imposed on Executive pursuant to Section 4999 of
               the Code. Except as otherwise noted below, this Gross-Up Payment
               will consist of a single lump sum payment in an amount such that
               after payment by Executive of the "total presumed federal and
               state taxes" and the excise taxes imposed by Section 4999 of the
               Code on the Gross-Up Payment (and any interest or penalties
               actually imposed), Executive would retain an amount of the
               Gross-Up Payment equal to the remaining excise taxes imposed by
               Section 4999 of the Code on Executive's Total Payments
               (calculated before the Gross-Up Payment). For purposes of
               calculating Executive's Gross-Up Payment, Executive's actual
               federal and state income taxes will not be used. Instead, Company
               will use Executive's "total presumed federal and state taxes."
               For purposes of this Agreement, Executive's "total presumed
               federal and state taxes" shall be conclusively calculated using a
               combined tax rate equal to the sum of the maximum marginal
               federal and applicable state income tax rates. The state tax rate
               for Executive's principal place of residence will be used and no
               adjustments will be made for the deduction of state taxes on the
               federal return, any deduction of federal taxes on a state return,
               the loss of itemized deductions or exemptions, or for any other
               purpose.

          (b)  Calculations. All determinations concerning whether a Gross-Up
               Payment is required pursuant to Section 8(a) and the amount of
               any Gross-Up Payment (as well as any assumptions to be used in
               making such determinations) shall be made by the Consultant
               selected pursuant to Section 7(c). The Consultant shall provide
               Executive and Company with a written notice of the amount of the
               excise taxes that Executive is required to pay and the amount of
               the Gross-Up Payment. The notice from the Consultant shall
               include any necessary calculations in support of its conclusions.
               All fees and expenses of the Consultant shall be paid by Company.
               Any Gross-Up


                                       12



                                                                    SECTION 8(b)

               Payment shall be made by Company within fifteen (15) days after
               the mailing of such notice. As a general rule, the Consultant's
               determination shall be binding on Executive and Company. The
               application of the excise tax rules of Section 4999, however, is
               complex and uncertain and, as a result, the Internal Revenue
               Service may disagree with the Consultant concerning the amount,
               if any, of the excise taxes that are due. If the Internal Revenue
               Service determines that excise taxes are due, or that the amount
               of the excise taxes that are due is greater than the amount
               determined by the Consultant, the Gross-Up Payment will be
               recalculated by the Consultant to reflect the actual excise taxes
               that Executive is required to pay (and any related interest and
               penalties). Any deficiency will then be paid to Executive by
               Company within fifteen (15) days of the receipt of the revised
               calculations from the Consultant. If the Internal Revenue Service
               determines that the amount of excise taxes that Executive paid
               exceeds the amount due, Executive shall return the excess to
               Company (along with any interest paid to Executive on the
               overpayment) immediately upon receipt from the Internal Revenue
               Service or other taxing authority. Company has the right to
               challenge any excise tax determinations made by the Internal
               Revenue Service. If Company agrees to indemnify Executive from
               any taxes, interest and penalties that may be imposed upon
               Executive (including any taxes, interest and penalties on the
               amounts paid pursuant to Company's indemnification agreement),
               Executive must cooperate fully with Company in connection with
               any such challenge. Company shall bear all costs associated with
               the challenge of any determination made by the Internal Revenue
               Service and Company shall control all such challenges. The
               additional Gross-Up Payments called for by the preceding
               paragraph shall not be made until Company has either exhausted
               its (or Executive's) rights to challenge the determination or
               indicated that it intends to concede or settle the excise tax
               determination. Executive must notify Company in writing of any
               claim or determination by the Internal Revenue Service that, if
               upheld, would result in the payment of excise taxes in amounts
               different from the amount initially specified by the Consultant.
               Such notice shall be given as soon as possible but in no event
               later than fifteen (15) days following Executive's receipt of
               notice of the Internal Revenue Service's position.

addressed as above (or to such other address as such party may designate in a
notice duly delivered as described above), and the third (3rd) business day
after the actual date of mailing shall constitute the time at which notice was
given.

         SECTION 10 - SEPARABILITY; LEGAL FEES. If any provision of this
Agreement shall be declared to be invalid or unenforceable, in whole or in part,
such invalidity or unenforceability shall not affect the remaining provisions
hereof which shall remain in full force and effect. In the event of a dispute by
Company, Executive or others as to the validity or enforceability of, or
liability under, any provision of this Agreement, Company shall reimburse
Executive for all reasonable legal fees and expenses incurred by him in
connection with such dispute if Executive substantially prevails in the dispute
and if Executive has not substantially prevailed in such dispute one-half (1/2)
the amount of all reasonable legal fees and expenses incurred by him in
connection with such dispute except to the extent Executive's position is found
by a tribunal of competent jurisdiction to have been frivolous.

         SECTION 11 - ASSIGNMENT AND ASSUMPTION. This contract shall be binding
upon and inure to the benefit of the heirs and representatives of Executive and
the assigns and successors of Company, but neither this Agreement nor any rights
or obligations hereunder shall be assignable or otherwise subject to
hypothecation by Executive (except by will or by operation of the laws of
intestate succession) or by Company, except that Company may assign this
Agreement to any successor (whether by merger, purchase or otherwise) to all or
substantially all of the stock, assets or business of Company.

         SECTION 12 - AMENDMENT. This Agreement may only be amended by written

                                       14



                                                                      SECTION 13

         SECTION 13 - NON-COMPETITION; NON-SOLICITATION; CONFIDENTIALITY.

          (a)  Executive represents that acceptance of employment under this
               Agreement and performance under this Agreement are not in
               violation of any restrictions or covenants under the terms of any
               other agreements to which Executive is a party.

          (b)  Executive acknowledges and recognizes the highly competitive
               nature of the business of Company and accordingly agrees that, in
               consideration of this Agreement, the rights conferred hereunder,
               and any payment hereunder, during the Term of Employment and for
               the two (2) year period following the termination of Executive's
               employment with Company, for any reason ("Non-Compete Term"),
               Executive shall not engage, either directly or indirectly, as a
               principal for Executive's own account or jointly with others, or
               as a stockholder in any corporation or joint stock association,
               or as a partner or member of a general or limited liability
               entity, or as an employee, officer, director, agent, consultant
               or in any other advisory capacity in any business other than
               Company or its subsidiaries which designs, develops,
               manufacturers, distributes, sells or markets the type of products
               or services sold, distributed or provided by Company or its
               subsidiaries during the two (2) year period prior to the date of
               termination (the "Business"); provided that nothing herein shall
               prevent Executive from owning, directly or indirectly, not more
               than five percent (5%) of the outstanding shares of, or any other
               equity interest in, any entity engaged in the Business and listed
               or traded on a national securities exchanges or in an
               over-the-counter securities market.

          (c)  During the Non-Compete Term, Executive shall not (i) directly or
               indirectly employ or solicit, or receive or accept the
               performance of services by, any active employee of Company or any
               of its subsidiaries who is employed primarily in connection with
               the Business, except in connection with general, non-targeted
               recruitment efforts such as advertisements and job listings, or
               directly or indirectly induce any employee of Company to leave
               Company, or assist in any of the foregoing, or (ii) solicit for
               business (relating to the Business) any person who is a customer
               or former customer of Company or any of its subsidiaries, unless
               such person shall have ceased to have been such a customer for a
               period of at least six (6) months.

          (d)  Executive shall not at any time (whether during or after his
               employment with Company) disclose or use for Executive's own
               benefit or purposes or the benefit or purposes of any other
               person, firm, partnership, joint venture, association,
               corporation or other business organization, entity or enterprise
               other than Company and any of its subsidiaries, any trade
               secrets, information, data, or other confidential information of
               the Company, including but not limited to, information relating
               to customers, development programs, costs, marketing, trading,
               investment, sales activities, promotion, credit and financial
               data, financing methods, plans or the business and affairs of
               Company generally, or of any subsidiary of Company, unless


                                       15



                                                                   SECTION 13(d)

               required to do so by applicable law or court order, subpoena or
               decree or otherwise required by law, with reasonable evidence of
               such determination promptly provided to Company. The preceding
               sentence of this paragraph (d) shall not apply to information
               which is not unique to Company or which is generally known to the
               industry or the public other than as a result of Executive's
               breach of this covenant. Executive agrees that upon termination
               of employment with Company for any reason, Executive will return
               to Company immediately all memoranda, books, papers, plans,
               information, letters and other data, and all copies thereof or
               therefrom, in any way relating to the business of Company and its
               subsidiaries, except that Executive may retain personal notes,
               notebooks and diaries. Executive further agrees that Executive
               will not retain or use for Executive's account at any time any
               trade names, trademark or other proprietary business designation
               used or owned in connection with the business of Company or its
               subsidiaries.

          (e)  It is expressly understood and agreed that although Executive and
               Company consider the restrictions contained in this Section 13 to
               be reasonable, if a final judicial determination is made by a
               court of competent jurisdiction that the time or territory or any
               other restriction contained in this Agreement is an unenforceable
               restriction against Executive, the provisions of this Agreement
               shall not be rendered void but shall be deemed amended to apply
               as to such maximum time and territory and to such maximum extent
               as such court may judicially determine or indicate to be
               enforceable. Alternatively, if any tribunal of competent
               jurisdiction finds that any restriction contained in this
               Agreement is unenforceable, and such restriction cannot be
               amended so as to make it enforceable, such finding shall not
               affect the enforceability of any of the other restrictions
               contained herein.

          (f)  As a condition to the receipt of any benefits described in this
               Agreement, Executive shall be required to execute an agreement
               pursuant to which Executive releases any claims he may have
               against Company and agrees to the continuing enforceability of
               the restrictive covenants of this Agreement.

          (g)  This Section 13 will survive the termination of this Agreement.

         SECTION 14 - REMEDIES. Executive acknowledges and agrees that Company's
remedies at law for a breach or threatened breach of any of the provisions of
Section 13 would be inadequate and, in recognition of this fact, Executive
agrees that, in the event of such a breach or threatened breach, in addition to
any remedies at law, Executive shall forfeit all payments otherwise due under
this Agreement and shall return any Severance Package payment made. Moreover,
Company, without posting any bond, shall be entitled to seek equitable relief in
the form of specific performance, temporary restraining order, temporary or
permanent injunction or any other equitable remedy which may then be available.


                                       16


         SECTION 15- SURVIVORSHIP. The respective rights and obligations of the
parties hereunder shall survive any termination of this Agreement to the extent
necessary to the intended preservation of such rights and obligations. The
provisions of this Section 15 are in addition to the survivorship provisions of
any other section of this Agreement.

         SECTION 16 - GOVERNING LAW; REVENUE AND JURISDICTION. If any judicial
or administrative proceeding or claim relating to or pertaining to this
Agreement is initiated by either party hereto, such proceeding or claim shall
and must be filed in a state or federal court located in Wayne County, Michigan
and such proceeding or claim shall be governed by and construed under Michigan
law, without regard to conflict of law and principals.

         SECTION 17 - DISPUTE RESOLUTION. Any dispute related to or arising
under this Agreement shall be resolved in accordance with the TriMas Dispute
Resolution Policy in effect at the time such dispute arises. The TriMas Dispute
Resolution Policy in effect at the time of this Agreement is attached to this
Agreement.

         SECTION 18 - EFFECT ON PRIOR AGREEMENTS. This Agreement contains the
entire understanding between the parties hereto and supersedes in all respects
any prior or other agreement or understanding, both written and oral, between
Company, any parent, subsidiary or affiliate of Company or any predecessor of
Company or parent, subsidiary, or affiliate of any predecessor of Company and
Executive.

         SECTION 19 - WITHHOLDING. Company shall be entitled to withhold from
payment any amount of withholding required by law.

         SECTION 20 - SECTION HEADINGS AND CONSTRUCTION. The headings of
sections in this Agreement are provided for convenience only and will not effect
its construction or interpretation. All references to "Section" or "Sections"
refer to the corresponding section or sections of this Agreement unless
otherwise specified. All words used in this Agreement will be construed to be of
such gender or number as circumstances require.

         SECTION 21 - COUNTERPARTS. This Agreement may be executed in one (1) or
more counterparts, each of which will be deemed to be an original copy of this
Agreement and all of which, when taken together, will be deemed to constitute
one and the same Agreement.
