2. TERM, RENT AND PAYMENT

         (a) The Rent payable hereunder and Lessee's right to use the Equipment
shall commence on the date of execution by Lessee of the Certificate of
Acceptance for such Equipment ("Basic Term Commencement Date"). The term of this
Agreement (the "Term") shall be the period specified in the applicable Schedule.
If any Term is extended, the word "Term"

                                      -2-
<PAGE>

shall be deemed to refer to all extended terms, and all provisions of this
Agreement shall apply during any extended terms, except as otherwise may be
specifically provided in writing.

         (b) Rent shall be paid to Lessor by wire transfer of immediately
available funds to: Bankers Trust New York, New York, New York 10006, Account
No. 50-202-962, ABA No. 021-001-033, or to such other account as Lessor may
direct in writing; and shall be effective upon receipt. Payments of periodic
Rent shall be in the amount set forth in, and due and allocated in accordance
with, the provisions of the applicable Schedule. In no event shall any Rent
payments be refunded to Lessee.

3. EARLY TERMINATION

         (a) So long as no Default shall have occurred and be continuing, at any
time during the Term, Lessee may, but not more than twice in any fiscal year,
upon 90 days' prior written irrevocable notice to Lessor, terminate this
Agreement with respect to any one or more Units of Equipment (each, an "Affected
Unit"), if Lessee certifies by a certificate of Lessee's Chief Financial Officer
to Lessor that each such Affected Unit has become economically obsolete or is
surplus to Lessee's and Guarantor's needs; provided however, that prior to the
second anniversary of the Basic Term Commencement Date, the aggregate value of
such Units (measured by Capitalized Cost) subject to termination shall not
exceed $5,000,000.00. The termination shall become effective on any Rent Payment
Date selected by Lessee occurring at least 90 days after such notice (the
"Termination Date").

         (b) In the case of a termination described in paragraph (a) above, at
any time within 45 days after notice from Lessee of its election to terminate
this Lease with respect to any such Affected Unit, Lessor may give Lessee notice
of its election to retain such Affected Unit. If Lessor shall have elected to
retain any such Affected Unit in accordance with the preceding sentence, on the
Termination Date Lessee shall pay to Lessor any periodic Rent due with respect
to such Affected Unit as of such Termination Date and any other Rent due on or
prior to such Termination Date, but will not be required to pay Stipulated Loss
Value with respect to such Affected Unit. On such Termination Date Lessee shall
deliver such Affected Unit to Lessor pursuant to the requirements of Section 11
(but without regard to the time periods set forth in Section 11), and such
Affected Unit shall cease to be leased hereunder.

         (c) In the case of a termination described in paragraph (a) above with
respect to any Affected Unit, during the period from the giving of such notice
of termination until 10 Business Days prior to the Termination Date and so long
as Lessor shall not have exercised its option pursuant to paragraph (b) above to
retain any Affected Unit, Lessee, as agent for Lessor and at Lessee's expense,
shall use commercially reasonable efforts to obtain the highest possible bids
from Persons other than, except with the prior consent of Lessor, Lessee,
Guarantor or their Affiliates to purchase such Affected Unit on the Termination
Date. Lessee shall notify Lessor in writing, at least 10 Business Days prior to
the Termination Date, of the amount and terms of each such bid that has
theretofore been submitted and the name and address of the party submitting such
bid. Lessee shall certify to Lessor that such bidder is not an Affiliate of
Lessee or Guarantor (unless previously consented to by Lessor). Each such bid
shall be a bona fide bid for payment in full in cash (such a bid is referred to
herein as a "Qualifying Bid"). Lessee shall deliver to Lessor, on reasonable
request, periodic reports of Lessee's progress in finding a bidder

                                      -3-
<PAGE>

for each Affected Unit subject to the termination notice. Lessor shall have the
right, directly or through agents or brokers, to solicit bids, but shall be
under no duty to solicit bids or to inquire into the efforts of Lessee to obtain
bids. If Lessor has not elected to retain such Affected Unit pursuant to
paragraph (b) above and no Qualifying Bids are received as of the Termination
Date, this Lease shall continue in full force and effect as to such Affected
Unit, notwithstanding Lessee's prior written notice pursuant to paragraph (a)
above. Such continuation shall not constitute a revocation pursuant to paragraph
(a) above nor prejudice in any way Lessee's right to terminate the Lease as of a
later date as to such Affected Unit.

         (d) If (i) Lessee shall have received a Qualifying Bid on or prior to
the tenth Business Day before the Termination Date, and (ii) Lessor shall have
received from Lessee notice of the highest Qualifying Bid and shall have
received from the bidder that shall have submitted the highest Qualifying Bid
for each such Affected Unit immediately available funds of the amount specified
in such bid, Lessor shall on the Termination Date, subject to the receipt of the
amounts payable pursuant to paragraph (e) hereof, transfer to such bidder all of
Lessor's right, title and interest to such Affected Unit AS-IS, WHERE-IS without
representation or warranty except as to the absence of any liens on such
Affected Unit. On such Termination Date, Lessee shall deliver such Affected Unit
to the purchasing bidder pursuant to the requirements of Section 11 (to the
extent required by the bidder, but without regard to the time periods set forth
in Section 11), and such Affected Unit shall cease to be leased hereunder. Any
funds received by Lessee for such Affected Unit shall be immediately paid over
to Lessor without deduction, set-off or adjustment of any kind. Lessee and
Lessor shall execute and deliver such documents evidencing such transfer and
take such further action as the purchaser shall reasonably request. Lessee shall
pay, on an after-tax basis, all reasonable costs and expenses incurred by Lessor
in connection with any transfer of, or attempt to find a Qualifying Bid for, the
Affected Unit pursuant to this Section 3.

         (e) In the case of any termination described in paragraph (a) above
with respect to any Affected Unit, unless Lessor has elected to retain such
Affected Unit being terminated pursuant to paragraph (b) above on the
Termination Date, Lessee shall pay to Lessor the sum of:

              (i) any periodic Rent due with respect to the Equipment as of such
         Termination Date; plus

              (ii) any other Rent due and unpaid as of such Termination Date
         (including any amounts for reasonable costs and expenses payable by
         Lessee as required by paragraph (d) above; plus

              (iii) the excess, if any, of (1) the Stipulated Loss Value of such
         Affected Unit as of such Termination Date over (2) the net proceeds
         actually realized on any sale thereof and paid over to Lessor, as the
         case may be, pursuant to paragraph (d) above.

Upon payment by Lessee of all required amounts as to such Affected Unit, the
obligation of Lessee to pay Rent with respect to such Affected Unit shall
terminate, such Affected Unit shall no longer be subject to this Agreement and
the Term with respect to such Affected Unit shall terminate.

                                      -4-

4. TAXES

         Except as provided in Section 15(c) hereof, Lessee shall have no
liability for taxes imposed by the United States of America or any State or
political subdivision thereof which are on or measured by the net income or
profit of Lessor. Lessee shall report (to the extent that it is legally
permissible) and pay prior to delinquency, subject to Lessee's right to contest
the same in accordance with clause (iii) of the definition of Permitted Lien,
all other taxes, fees and assessments due, imposed, assessed or levied against
any Equipment (or the purchase, ownership, delivery, leasing, possession, use or
operation thereof), this Agreement (or any Rents or receipts hereunder), any
Schedule, Lessor or Lessee by any foreign, United States federal, state or local
government or taxing authority in any of the foregoing during or related to the

registration fees, and all sales, use, personal property, excise, gross
receipts, value added, franchise, stamp or other taxes, imposts, duties and
charges, other than those taxes contemplated in the first sentence of this
Section 4, together with any penalties, fines or interest thereon (all
hereinafter called "Taxes"). Lessee shall (i) reimburse Lessor (on an after-tax
basis) upon receipt of written request for reimbursement for any Taxes charged
to or assessed against Lessor, (ii) on request of Lessor, submit to Lessor
written evidence of Lessee's payment of Taxes, (iii) on all reports or returns
show the ownership of the Equipment by Lessor, and (iv) send a copy thereof to
Lessor. At Lessor's request, Lessee, as Lessor's agent (pursuant to an Agency
Agreement to be agreed upon), shall pay directly any such taxes imposed.

5. REPORTS

         (a) Lessee will notify Lessor in writing, within 10 days after
obtaining actual knowledge, or after Lessee shall have received written notice

notification.

         (c) Lessee will promptly and fully report to Lessor in writing if any
Unit of Equipment is lost or damaged (where the estimated repair costs would
exceed the greater of 10% of its then fair market value or $50,000), or is
otherwise involved in an accident causing personal injury or property damage,
excluding claims for worker's compensation.

         (d) Within 30 days after any request by Lessor and in connection with
any financial statement delivered pursuant to paragraph (b) above, Lessee will
furnish a certificate of an authorized officer of Lessee stating that he has
reviewed the activities of Lessee and that, to the

                                      -5-
<PAGE>

best of his knowledge, there exists no Default or event which, with the giving
of notice or the lapse of time (or both), would become a Default.

         (e) Lessee will deliver to Lessor copies of all notices, statements,
reports and other items required to be delivered by Lessee under the Credit

              (v) If such new location is subject to a lease or mortgage, Lessee
         shall deliver to Lessor a fully executed Estoppel/Waiver, in form of
         Annex E hereto or otherwise in substance satisfactory to Lessor, from

         remaining economic useful life at least equal to the fair market and

         Unit, assuming such Old Unit has been maintained in the condition
         required by this Agreement, and (C) is of the same or newer date of
         manufacture as the replaced Part;

              (v) Lessor shall have received a duly executed full warranty bill
         of sale for such Replacement Unit and title to such Unit shall have
         vested in Lessor, free and clear of all Liens;

         expenses (including the lease payments due on the Equipment);

              (iii) Comprehensive General Liability Insurance. Lessee shall

         occurrence basis with a limit of not less than $1,000,000. Such

         liability. Such insurance shall not contain an exclusion for punitive
         or exemplary damages where insurable by law;

         (b) Endorsements. Lessee shall cause all insurance policies carried and
maintained in accordance with this Section 10 to be endorsed as follows:

              (i) Lessee shall be the named insured and Lessor shall be an
         additional named insured and sole loss payee as its interest may appear
         with respect to the Equipment covered by property policies described in
         subsection (a)(i). Lessee shall be the named insured and Lessor shall
         be an additional insured with respect to liability policies described
         in subsections (a)(iii), (a)(iv) to the extent allowed by law and
         (a)(v). It shall be understood that any obligation imposed upon Lessee,
         including but not limited to the obligation to pay premiums, shall be

              (ii) With respect to property policies described in subsections
         (a)(i) and (a)(ii), the interests of Lessor shall not be invalidated by

         Lessor regardless of any breach or violation by Lessee or any other
         person, of any warranties, declarations or conditions of such policies;

              (iii) Inasmuch as the liability policies are written to cover more
         than one insured, all terms conditions, insuring agreements and
         endorsements, with the exception of the limits of liability, shall
         operate in the same manner as if there were a separate policy covering
         each insured;

              (iv) The insurers thereunder shall waive all rights of subrogation
         against Lessor any right of setoff or counterclaim and any other right
         to deduction, whether by attachment or otherwise.

              (v) Such insurance shall be primary without right of contribution
         of any other insurance carried by or on behalf of Lessor with respect
         to their interests as such in the Equipment; and

              (vi) If such insurance is canceled for any reason whatsoever,
         including nonpayment of premium, or any changes are initiated by Lessee
         or the carrier which affect the interests of Lessor, such cancellation
         or change shall not be effective as to Lessor until 30 days, except for
         non-payment of premium which shall be 10 days, after receipt by Lessor
         of written notice sent by registered mail from such insurer.

         (c) Certifications. On the Base Lease Commencement Date with respect to
the Equipment leased as of such date, and at each policy renewal, but not less
than annually with respect to all Equipment then leased, Lessee shall provide to
Lessor a certification from each insurer or by an authorized representative of
each insurer. Such certification shall identify the underwriters, the type of
insurance, the limits, deductibles, and term thereof and shall specifically list
the special provisions delineated for such insurance required for this Section
10.

         (d) Insurance Report. Concurrently with the furnishing of all
certificates referred to in this Section 10, Lessee shall furnish Lessor with a
statement from an independent insurance broker, acceptable to Lessor, stating
that all premiums then due have been paid.

         the manufacturer's specifications; and (C) if during such inspection,
         examination and test, the Authorized Inspector finds any of the
         material or workmanship, as expected for the age of the Equipment, to
         be defective or the equipment not operating within the manufacturer's
         specifications, then Lessee shall repair or replace such defective
         material and, after corrective measures are completed Lessee will
         provide for another inspection of the equipment by the Authorized
         Inspector as outlined above.

              (iv) Have each Unit of Equipment returned with an in-depth field
         service report detailing said inspection as outlined in clause (iii)

         inspected, examined and tested and is operating within the
         manufacturer's specifications;

              (v) At least 45 days prior to the scheduled expiration of the
         Lease and upon request by Lessor provide to Lessor, the following
         documents: (A) one set of service and operating manuals including
         replacements and/or additions hereto, such that all documentation is
         completely up to date; and, (B) if any, one set of documents detailing
         equipment configuration, operating requirements, maintenance records,
         and other technical data concerning the set-up and operation of the
         Equipment including replacements and additions thereto, such that all
         documentation is completely up to date.

              (vi) Provide for the deinstallation, packing and transporting of
         the Equipment to include, but not limited to, the following: (A) the
         manufacturer's representative shall de-install all Equipment (including
         all wire, cable and mounting hardware); (B) all process fluids shall be
         removed from the Equipment and disposed of in accordance with then
         current waste disposal laws and regulations including regulations
         specified by the Environmental Protection Agency (EPA) and related
         government agencies; (C) dismantling and handling is to be done per the
         original manufacturer's specifications or normal industry accepted
         practices for new machines must be followed. Any special transportation
         devices such as metal skids, lifting slings, brackets, etc., which were
         with the machine when it originally arrived must be used to the extent
         available, or otherwise, Lessee shall use such other devices as will
         assure the safety of such Equipment being transported; (D) all keys
         belonging to the Equipment are to be wired together and secured to a
         major component of the machine; (E) Lessee shall provide for
         transportation of the Equipment in a manner consistent with the
         manufacturer's recommendations and practices to a location within the
         continental United States which is no more than 1500 miles from the
         Equipment's current location; and (F) Lessee shall obtain and pay for a
         policy of transit insurance for the delivery period in an amount equal
         to the replacement value of the Equipment with Lessor named as loss
         payee on all such policies of insurance; and (G) Lessee shall provide
         safe, secure storage for the Equipment for a period of up to 90 days

         location reasonably satisfactory to Lessor.

              (vii) Ensure all Equipment and equipment operations conform to all
         Applicable Laws.

              (viii) Permit, with Lessee's full cooperation and assistance,

         Equipment from Lessee's facility for a period from 60 days prior to 90
         days after expiration of this Lease. During this period, the equipment
         must remain operational with the necessary electrical power, lighting,
         heat, water, lubricating fluids, air pollution controls and compressed
         air necessary to maintain and demonstrate the Equipment to any
         potential buyer. Any such resale will be conducted no more than 60 days
         prior to the scheduled Lease expiration and will be conducted in a
         manner which will not interfere with Lessee's business operations.

         (b) Until Lessee fully has complied in all material respects with the
requirements of subsections (i)-(vii) of paragraph (a) above, Lessee's Rent
payment obligation at a rental equal to the greater of the periodic Rent payable
in respect of such Unit of Equipment and the Fair Market Rental Value of such
Equipment and all other obligations under this Agreement shall continue until
all Units of Equipment have been returned in accordance with the terms hereof.
If any Unit is not returned to Lessor within 60 days after the expiration of
this Agreement, Lessor, at its election, may deem such Unit to have suffered a
Casualty Occurrence, in which event, Lessee shall pay to Lessor the greater of
the Fair Market Value or the Stipulated Loss Value of such Unit. In addition to
these Rents, Lessor shall have all of its other rights and remedies available as
a result of this nonperformance.

         (d) The foregoing remedies are cumulative, and any or all thereof may
be exercised in lieu of or in addition to each other or any remedies at law, in
equity, or under statute. Lessee waives notice of sale or other disposition (and
the time and place thereof), and the manner and place of any advertising. If
permitted by Applicable Law, Lessee shall pay reasonable attorney's fees
actually incurred by Lessor in enforcing the provisions of this Agreement and
any ancillary documents. Waiver of any Default shall not be a waiver of any
other or subsequent default.

         (e) Unless previously terminated or cancelled, upon payment of all
amounts due hereunder, this Agreement shall terminate.

13. ASSIGNMENT

         (a) LESSEE SHALL NOT ASSIGN, MORTGAGE, SUBLET OR HYPOTHECATE ANY
EQUIPMENT OR THE INTEREST OF LESSEE HEREUNDER WITHOUT THE PRIOR WRITTEN CONSENT
OF LESSOR.

         (b) Lessor may, without the consent of Lessee, assign this Agreement or
any Schedule, or the right to enter into any Schedule, provided, that so long as
no Default has occurred and is continuing, Lessor will not assign this
Agreement, or any Schedule or the right to enter into any Schedule to a
Competitor of Lessee. Lessee agrees that it will pay all Rent and other amounts
payable under each Schedule to Lessor named therein; provided, however, if
Lessee receives written notice of an assignment from Lessor, Lessee will pay all
Rent and other amounts payable under any assigned Schedule to such assignee or
as instructed by Lessor. Each Schedule, incorporating by reference the terms and
conditions of this Agreement, constitutes a separate instrument of lease, and
Lessor or its assignee shall have all rights as "Lessor" thereunder separately
exercisable by such named Lessor or assignee as the case may be, exclusively and
independently of Lessor or any assignee with respect to other Schedules executed
pursuant hereto. Lessee agrees reasonably to cooperate with Lessor in connection
with any such proposed assignment, including the execution and delivery of such
other documents, instruments, notices, opinions, certificates and
acknowledgments, as reasonably may be required by Lessor or such assignee; and
Lessee further agrees to confirm in writing receipt of a notice of assignment as
reasonably may be requested by assignee. Lessee hereby waives and agrees not to
assert against any such assignee any defense, set-off, recoupment claim or
counterclaim that Lessee has or may at any time have against Lessor or any other
Person for any reason whatsoever.

         (c) Subject always to the foregoing, this Agreement inures to the
benefit of, and is binding upon, the successors and assigns of the parties
hereto.

14. NET LEASE; NO SET-OFF, ETC

         This Agreement is a net lease. Lessee's obligation to pay Rent and
other amounts due hereunder shall be absolute and unconditional. Lessee shall
not be entitled to any abatement or reductions of (except as expressly provided
herein in respect of any Unit which ceases to be subject to this Agreement), or
set-offs against, said Rent or other amounts, including, without limitation,
those arising or allegedly arising out of claims (present or future, alleged or
actual, and including claims arising out of strict tort or negligence of Lessor)
of Lessee against Lessor

                                      -16-
<PAGE>

under this Agreement or otherwise. Except as provided in Section 8 hereof, with
respect to any Unit that shall have suffered a Casualty Occurrence, this
Agreement shall not terminate and the obligations of Lessee shall not be
affected by reason of any defect in or damage to, or loss of possession, use or
destruction of, any Equipment from whatsoever cause. It is the intention of the
parties that Rents and other amounts due hereunder shall continue to be payable
in all events in the manner and at the times set forth herein unless the
obligation to do so shall have been terminated pursuant to the express terms
hereof.

15. INDEMNIFICATION

         (a) Lessee hereby agrees to defend, indemnify, save and keep harmless
(on an after-tax basis), Lessor, its agents, employees, successors and assigns,
from and against any and all losses, damages, penalties, injuries, claims,
actions and suits (herein a "Claim"), including reasonable legal expenses, of
whatsoever kind and nature, in contract or tort, whether caused by the active or
passive negligence of Lessor or otherwise, and including, but not limited to,
Lessor's strict liability in tort, arising out of the selection, manufacture,
purchase, acceptance or rejection of Equipment, the ownership of Equipment
during the Term, and the delivery, lease, possession, maintenance, uses,
condition, return or operation of the Equipment (including, without limitation,
latent and other defects, whether or not discoverable by Lessor or Lessee and
any claim for patent, trademark or copyright infringement or environmental loss
or damage); provided that such indemnity shall not be available to the extent
(i) such Claim is attributable to the gross negligence, willful misconduct or
breach of this Agreement by such indemnified party, or (ii) such Claim arises
and relates to periods after the later of (x) the termination or expiration of
the Agreement or (y) the return of the Equipment in accordance with the terms
hereof. Lessee shall, upon request, defend any actions based on, or arising out
of, any of the foregoing.

         (b) This Agreement has been entered into on the assumption that (i)
this Agreement will be treated for Federal income tax purposes as a true lease
and Lessor will be treated as the owner and lessor of the Equipment and Lessee
will be treated as Lessee of the Equipment, and (ii) on the Basic Term
Commencement Date for any Unit of Equipment, such Unit will qualify for all of
the items of deduction and credit specified in Section C of the applicable
Schedule ("Tax Benefits") in the hands of Lessor (all references to Lessor in
this Section include Lessor and its assignees and the consolidated taxpayer
group of which Lessor and any assignee is a member).

         (c) If for any reason whatsoever (i) tax counsel of Lessor reasonably
acceptable to Lessee shall determine that due to a change in fact or law there
is not a reasonable basis for Lessor to claim, or Lessor is required to reduce,
defer, recompute or recapture, on its Federal income tax return all or any
portion of the Tax Benefits with respect to any Equipment, or (ii) any such Tax
Benefit claimed on the Federal income tax return of Lessor is disallowed,
reduced, deferred, recomputed or recaptured by the Internal Revenue Service, or
(iii) Lessor shall become liable for additional tax as a result of Lessee having
made a substitution or Lessee having added an attachment or made an alteration
to the Equipment, including (without limitation) any such attachment or
alteration which would increase the productivity or capability of the Equipment
so as to violate the provisions of Rev. Proc. 75-21, 1975-1 C.B. 715, or Rev.
Proc. 79-48, 1979-2 C.B. 529 (as either or both may hereafter be modified or
superseded), (any such determination, disallowance, adjustment, recomputation or
recapture being hereinafter called a "Loss"), then

                                      -17-
<PAGE>

Lessee shall pay to Lessor, as an indemnity and as additional Rent, such amount
as shall, in the reasonable opinion of Lessor, cause Lessor's after-tax economic
yields and cash flows, computed on the same assumptions, including tax rates as
were utilized by Lessor in originally evaluating the transaction (such yields
and flows being hereinafter called the "Net Economic Return") to equal the Net
Economic Return that would have been realized by Lessor if such Loss had not
occurred. Such amount shall be payable upon demand after Lessor has suffered a
Loss accompanied by a statement describing in reasonable detail such Loss and
the computation of such amount. Anything in this Section to the contrary
notwithstanding, Lessee shall have no obligation to indemnify Lessor from or
against any such Loss to the extent that such Loss is caused by: (i) any failure
by Lessor to properly or timely claim on its Federal income tax return any Tax
Benefits on any Equipment (unless such failure is based upon a determination by
tax counsel of Lessor reasonably acceptable to Lessee that Lessor is not
entitled to claim such Tax Benefits with respect to such Equipment); (ii) any
failure of Lessor to have sufficient taxable income to benefit from the Tax
Benefits; (iii) any liability of Lessor for any alternative minimum taxes; (iv)
the status of Lessor as taxable corporation as for purposes of Federal income
taxes; (v) any sale or other disposition of any Equipment by Lessor other than
after a Default by Lessee; (vi) any tax election made or not made by Lessor
relating to the Tax Benefits; or (vii) any event which results in a payment by
Lessee in an amount equal to, or measured by, the Stipulated Loss Value to the
extent that such Loss was included in Lessor's calculation of such Stipulated
Loss Value.

         (d) Lessee shall defend, indemnify (on an after-tax basis) and hold
harmless Lessor and its Affiliates, successors and assigns, directors, officers,
employees and agents, from and against any Environmental Loss and, unless Lessee
is then contesting in good faith such Environmental Loss and Lessee has set
aside on its books appropriate reserves therefor, Lessee shall fully and
promptly pay, perform and discharge any such Environmental Loss.

16. DISCLAIMER

         LESSEE ACKNOWLEDGES THAT IT HAS SELECTED THE EQUIPMENT WITHOUT ANY
ASSISTANCE FROM LESSOR, ITS AGENTS OR EMPLOYEES. LESSOR DOES NOT MAKE, HAS NOT
MADE, NOR SHALL BE DEEMED TO MAKE OR HAVE MADE, ANY WARRANTY OR REPRESENTATION,
EITHER EXPRESS OR IMPLIED, WRITTEN OR ORAL, WITH RESPECT TO THE EQUIPMENT LEASED
HEREUNDER OR ANY COMPONENT THEREOF, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY
AS TO DESIGN, COMPLIANCE WITH SPECIFICATIONS, QUALITY OF MATERIALS OR
WORKMANSHIP, MERCHANTABILITY, FITNESS FOR ANY PURPOSE, USE OR OPERATION, SAFETY,
PATENT, TRADEMARK OR COPYRIGHT INFRINGEMENT, OR TITLE. All such risks, as
between Lessor and Lessee, are to be borne by Lessee. Without limiting the
foregoing, Lessor shall have no responsibility or liability to Lessee or any
other Person with respect to any of the following (i) any liability, loss or
damage caused or alleged to be caused directly or indirectly by any Equipment,
any inadequacy thereof, any deficiency or defect (latent or otherwise) therein,
or any other circumstance in connection therewith; (ii) the use, operation or
performance of any Equipment or any risks relating thereto; (iii) any
interruption of service, loss of business or anticipated profits or
consequential damages; or (iv) the delivery, operation, servicing, maintenance,
repair, improvement or replacement of any Equipment. If, and so long

                                      -18-
<PAGE>

as, no default exists under this Agreement, Lessee shall be, and hereby is,
authorized during the term of this Agreement to assert and enforce, at Lessee's
sole cost and expense, from time to time, in the name of and for the account of
Lessor and/or Lessee, as their interests may appear, whatever claims and rights
Lessor may have against any Supplier of the Equipment.

17. REPRESENTATIONS, WARRANTIES AND COVENANTS OF LESSEE

         (a) Lessee hereby represents and warrants to Lessor that on the date
hereof and on the date of execution of each Schedule:

              (i) Lessee is a corporation duly organized, validly existing and
         in good standing under the laws of the state of its incorporation
         (specified in the first sentence of this Agreement); and is duly
         qualified to transact business as a foreign corporation in good
         standing wherever necessary to carry on its present business and
         operations, including the jurisdictions where the Equipment is or is to
         be located, except where the failure to be so qualified or to be in
         good standing would not have a Material Adverse Effect.

              (ii) This Agreement, the Schedules, the Bill of Sale and all
         related documents (collectively, the "Documents") have been duly
         authorized, executed and delivered by Lessee and constitute valid,
         legal and binding agreements, enforceable in accordance with their
         terms, except to the extent that the enforcement of remedies therein
         provided may be limited under applicable bankruptcy and insolvency
         laws, public policy and equitable principles.

              (iii) No approval, consent or withholding of objections is
         required from any Governmental Authority with respect to the entry into
         or performance by Lessee of the Documents except such as have already
         been obtained or those, which if not obtained, would not have a
         Material Adverse Effect, individually or in the aggregate.

              (iv) Lessee has adequate power and capacity to enter into, and
         perform under, the Documents. The entry into and performance by Lessee
         of the Documents will not: (i) violate any judgment, order, law or
         regulation applicable to Lessee or any provision of Lessee's charter or
         by-laws; or (ii) result in any breach of, constitute a default under or
         result in the creation of any Lien upon any Equipment pursuant to any
         indenture, mortgage, deed of trust, bank loan or credit agreement or
         other instrument (other than this Agreement) to which Lessee is a
         party.

              (v) There are no suits or proceedings pending or to Lessee's
         knowledge threatened in court or before any commission, board or other
         administrative agency against or affecting Lessee, which will have a
         Material Adverse Effect. As used herein, "Material Adverse Effect"
         shall mean (1) a materially adverse effect on the operations,
         properties, assets, financial condition, contingent or otherwise, or
         material agreements of Lessee or any of Lessee's Affiliates or
         Guarantor or any of Guarantor's Affiliates in each case taken as a
         whole, or (2) a material impairment of the ability of Lessee to perform
         its obligations under or to remain in compliance with the Documents.

                                      -19-
<PAGE>

              (vi) The chief executive office and chief place of business (as
         either of such terms is used in Article 9 of the UCC) of Lessee is
         located at 47603 Halyard Drive, Plymouth, Michigan 48170-2429.

              (vii) The Equipment accepted under any Certificate of Acceptance
         is and will remain tangible personal property and is not and shall not
         constitute real property fixtures.

              (viii) Each financial statement delivered by Lessee to Lessor has
         been prepared in accordance with GAAP, and since the date of the most
         recent annual audited financial statement, there has been no material
         adverse change in the financial condition of Lessee and its
         consolidated Subsidiaries or of Guarantor and its consolidated
         Subsidiaries other than as result of the recapitalization of MascoTech
         on November 28, 2000 and the acquisition of the Lessee on December 15,
         2000.

              (ix) Each representation and warranty of Lessee made in the Credit
         Agreement is true and correct in all material respects when made.

              (x) During the 12 months ending September 30, 2000, the
         manufacturing facilities of Lessee, which are located in the United
         States generated at least 75% of its net revenues during such period.

              (xi) Each Equipment Location identified on the Schedule is owned
         by Lessee free and clear of any liens for indebtedness or leases.

         (b) Lessee hereby covenants and agrees with Lessor that:

              (i) The Equipment will at all times be used for commercial or
         business purposes.

              (ii) Lessee shall maintain a system of identification number
         tagging on all the Equipment and any Part thereof which will identify
         the manufacturer, serial numbers and type and model of Equipment as set
         forth in Annex A to the Schedule.

              (iii) Lessee, at its sole cost and expense shall establish,
         implement and maintain a formal, comprehensive written environmental,
         health and safety ("EH&S") program ("EH&S Program") aimed at ensuring
         that Lessee's operation at the Equipment Locations are conducted in
         compliance with all applicable Environmental Laws and ISO 14001.
         Lessee's operations at each Equipment Location shall be ISO 14001
         compliant at all times after December 31, 2003. At a minimum, the EH&S
         Program include: (A) identification of environmental concerns
         associated with an environmental regulations applicable to Lessee's
         operations; (B) adoption and implementation of an environmental
         management system to assess and control the environmental impacts of
         Lessee's operations; (C) implementation of periodic EH&S audits by or
         involving an independent third-party consultant with documented
         corrective action responding to audits; (D) effective labeling of
         products and services; (v) employee EH&S committees, for ensuring
         compliance with Environmental Laws; and (E) such other requirements as
         Lessor may reasonably require from Lessee from time to time. The EH&S
         Program must involve

                                      -20-
<PAGE>

         senior management, include a formal written corporate environmental
         policy, and identify by name or position the person with overall
         responsibility for EH&S compliance, as well as those person(s) who are
         responsible for specific EH&S areas.

              (iv) At Lessor's request (not more frequently than once in any
         12-month period, unless a Default shall have occurred and be
         continuing), Lessee shall provide Lessor with a briefing regarding
         Lessee's EH&S Program.

              (v) If Lessee pays to the lenders under the Credit Agreement any
         compensation in connection with securing their approval of any waiver
         or amendment to the Credit Agreement (other than amendments having no
         adverse effect on Lessor), Lessee shall simultaneously pay to Lessor
         equivalent compensation, calculated on the same basis as calculated in
         respect of each such lender. If such compensation is based on the
         outstanding loan indebtedness from such lender to Lessee, in respect of
         Lessor it shall be based on the then Casualty Value of the Equipment.

18. INTENT; TITLE

         (a) It is the express intent of the parties that this Agreement
constitutes a true lease and not a sale of the Equipment. Title to the Equipment
shall at all times remain in Lessor, and Lessee shall acquire no ownership,
title, property, right, equity, or interest in the Equipment other than its
leasehold interest solely as Lessee subject to all the terms and conditions
hereof. The parties agree that the lease is a "Finance lease" as defined in UCC
Article 2A -- Leases ("Article 2A"). Lessee acknowledges: (1) that Lessee has
selected the "Supplier" (as defined in Article 2A); and (2) that Lessee has been
informed in writing in this Lease, before signing this Lease, that Lessee is
entitled under Article 2A to the promises and warranties, including those of any
third party, provided to Lessor by the Supplier in connection with or as part of
the contract by which Lessor acquired the Equipment, and that Lessee may
communicate with the Supplier and receive an accurate and complete statement of
those promises and warranties, including any disclaimers and limitations of them
or of remedies. To the extent permitted by applicable law, Lessee hereby waives
any and all rights and remedies conferred upon a lessee in Article 2A and any
rights now or hereafter conferred by statute or otherwise which may limit or
modify any of Lessor's rights or remedies under Section 12 hereof; provided,
however, that such waiver shall not preclude Lessee from asserting any claim of
Lessee against Lessor in a separate cause of action; and provided further that
such waiver shall not affect Lessor's obligations of good faith, diligence,
reasonableness and care.

         (b) Notwithstanding the express intent of the parties, should a court
of competent jurisdiction determine that this Agreement is not a true lease, but
rather one intended as security, then solely in that event and for the expressly
limited purposes thereof, Lessee shall be deemed to have hereby granted Lessor a
security interest in the lease, the Equipment, and all accessions thereto,
substitutions and replacements therefor, and proceeds (including insurance
proceeds) thereof (but without power of sale); to secure the prompt payment and
performance as and when due of all obligations and indebtedness of Lessee (or
any affiliate of Lessee) to Lessor, now existing or hereafter created. For the
purposes of this paragraph, this Agreement, the Schedule, or a photocopy of
either thereof may be filed as a financing statement under the UCC.

                                      -21-
<PAGE>

19. PURCHASE AND RENEWAL OPTIONS

         Provided no Default shall have occurred and be continuing, Lessee shall
have the option upon the expiration of the Term to renew the Term of this
Agreement with respect to, or to purchase, all (but not less than all) of the
Equipment leased under all Schedules executed hereunder upon the following terms
and conditions.

         (a) Upon expiration of the Basic Term or any Renewal Term, Lessee may
elect to renew the Term with respect to all, but not less than all, of the
Equipment leased under all Schedules executed hereunder for a Renewal Term of 2
years, subject to receipt of an appraisal satisfactory to Lessor as to the
residual value and remaining useful life of the Equipment, at a periodic Rent
equal to the Fair Market Rental Value of the Equipment.

         (b) Lessee may elect to purchase, at expiration of the Basic Term or
any Renewal Term, all (but not less than all) of the Equipment leased under all
Schedules executed hereunder on an AS IS BASIS, for cash equal to the then Fair
Market Value of the Equipment, plus (in any event) all applicable sales taxes.
On the last day of the Term, Lessor shall receive in cash the full purchase
price (plus all applicable sales taxes), together with any Rent or other sums
then due hereunder on such date.

         (c) If a Default shall have occurred and be continuing at the time of
the notice in the first sentence of paragraph (d) below, then on the date of
expiration of the Term, Lessee shall return the Equipment in full compliance
with Section 11 of this Agreement on or prior to the date of expiration of the
Term. If Lessee shall have given the notice provided in the first sentence of
paragraph (d) below, and a Default occurs and is continuing at the expiration of
this Lease, Lessor may elect either to enforce the option exercised by Lessee or
demand return of the Equipment in full compliance with Section 11 of this
Agreement.

         (d) Lessee shall give Lessor not less than 365 days' irrevocable
written notice of whether Lessee shall exercise either of its options pursuant
to paragraphs (a) or (b) above. Failure to give such notice shall be deemed an
election to purchase the Equipment. If Lessee timely elects to exercise its
options pursuant to paragraphs (a) or (b) above, Lessee shall give Lessor at
least 90 days' irrevocable written notice to Lessor prior to the expiration of
the Term of its election of either the option under paragraph (a) or the option
under paragraph (b). Failure to give such notice shall be deemed to be an
election to exercise the option under paragraph (b) above.

20. MISCELLANEOUS

         (a) LESSEE AND LESSOR HEREBY UNCONDITIONALLY WAIVE THEIR RIGHTS TO A
JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF,
DIRECTLY OR INDIRECTLY, THIS AGREEMENT, ANY OF THE RELATED DOCUMENTS, ANY
DEALINGS BETWEEN LESSEE AND LESSOR RELATING TO THE SUBJECT MATTER OF THIS
TRANSACTION OR ANY RELATED TRANSACTIONS, AND/OR THE RELATIONSHIP THAT IS BEING
ESTABLISHED BETWEEN LESSEE AND LESSOR. THE SCOPE OF THIS WAIVER IS INTENDED TO
BE ALL ENCOMPASSING OF ANY AND ALL DISPUTES THAT

                                      -22-
<PAGE>

MAY BE FILED IN ANY COURT (INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT
CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS).
THIS WAIVER IS IRREVOCABLE MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR
IN WRITING, AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS,
SUPPLEMENTS OR MODIFICATIONS TO THIS LEASE, ANY RELATED DOCUMENTS, OR TO ANY
OTHER DOCUMENTS OR AGREEMENTS RELATING TO THIS TRANSACTION OR ANY RELATED
TRANSACTION. In the event of litigation, this Agreement may be filed as a
written consent to a trial by the court.

         (b) Any cancellation or termination by Lessor, pursuant to the
provision of this Agreement, any Schedule, supplement or amendment hereto, or
the lease of any Equipment hereunder, shall not release Lessee from any then
outstanding obligations to Lessor hereunder.

         (c) Time is of the essence of this Agreement. Lessor's failure at any
time to require strict performance by Lessee of any of the provisions hereof
shall not waive or diminish Lessor's right thereafter to demand strict
compliance therewith.

         (d) Lessee agrees, upon Lessor's request, to execute any instrument
necessary or expedient for filing, recording or perfecting the interest of
Lessor, and to execute and deliver to Lessor such further documents, instruments
and assurances and to take such further action as Lessor from time to time
reasonably may request in order to carry out the intent and purpose of the
transaction contemplated hereunder.

         (e) All notices required to be given hereunder shall be in writing,
personally delivered, delivered by overnight courier service, sent by facsimile
transmission (with confirmation of receipt), or sent by certified mail, return
receipt requested, addressed to the other party at its respective address stated
above or at such other address as such party shall from time to time designate
in writing to the other party; and shall be effective from the date of receipt.

         (f) This Agreement, the Exhibits and each Schedule and Annexes thereto
constitute the entire agreement of the parties with respect to the subject
matter hereof. NO VARIATION OR MODIFICATION OF THIS AGREEMENT OR ANY WAIVER OF
ANY OF ITS PROVISIONS OR CONDITIONS, SHALL BE VALID UNLESS IN WRITING AND SIGNED
BY AN AUTHORIZED REPRESENTATIVE OF THE PARTIES HERETO.

         (g) The representations, warranties and covenants of Lessee herein
shall be deemed to survive the closing hereunder. The obligations of Lessee
under Sections 4, 11 and 15 hereof which accrue during the term of this
Agreement and obligations which by their express terms survive the termination
of this Agreement, shall survive the termination of this Agreement.

         (h) In case of a failure of Lessee to comply with any provision of this
Agreement, Lessor shall have the right, but shall not be obligated, to effect
such compliance, in whole or in part; and all moneys spent and expenses and
obligations incurred or assumed by Lessor in effecting such compliance (together
with interest thereon at the Overdue Rate) shall constitute additional Rent due
to Lessor within 5 days after the date Lessor sends notice to Lessee

                                      -23-
<PAGE>

requesting payment. Lessor's effecting such compliance shall not be a waiver of
Lessee's default.

         (i) Any Rent or other amount not paid to Lessor when due hereunder
shall bear interest, both before and after any judgment or termination hereof,
at the lesser of 15% per annum or the maximum rate allowed by law (the "Overdue
Rate").

         (j) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

         (k) So long as no Default shall have occurred and be continuing
hereunder, and conditioned upon Lessee performing all of the covenants and
conditions hereof, as to claims of Lessor or Persons claiming under Lessor,
Lessee shall peaceably and quietly hold, possess and use the Equipment during
the Term of this Agreement subject to the terms and conditions hereof.

         (l) Lessee agrees to pay on demand all reasonable costs and expenses
incurred by Lessor and any assignee in connection with the preparation,
execution, delivery, filing, recording, and administration of any of the

Market Value or Fair Market Rental Value, as the case may be, of the Equipment,
the Fair Market Value or Fair Market Rental Value, as the case may be, shall be
determined in accordance with the appraisal procedure set forth in this
definition. If either party shall have given written notice to the other
requesting determination of such Fair Market Value or Fair Market Rental Value
by such appraisal procedure, the parties shall consult for the purpose of
appointing a qualified independent appraiser by mutual agreement. If a single

         period. The appraisal determined by each appraiser shall be compared
         and if the differential between the two is less then 10% of the average
         of the two appraisers, then such average of the two appraisals shall be
         final and binding upon the parties; but

         promptly appointed by the American Arbitration Association of New York,
         in accordance with its rules as then in effect. The appraisals
         determined by each of the three appraisers shall be averaged and the
         appraisal furthest from such average shall be disregarded. The
         appraisals determined by each of the two remaining appraisers shall be
         averaged and such average shall be final and binding upon the parties.

to appraise in accordance with, the definitions of all terms appearing herein

he intends to resign his position to pursue other opportunities, including a
continuing relationship with the Company's affiliate, Masco Corporation. The
Executive, at the request of the Company, has agreed to provide consulting
services to the Company through December 31, 2003, on the terms and conditions
provided herein.

         D. The Executive and the Company desire to memorialize the terms and
conditions of their agreement.

         NOW, THEREFORE, in consideration of the foregoing and of the promises
and mutual covenants contained herein, it is hereby agreed between the Executive
and the Company as follows:

         1. Effectiveness of Agreement. This Agreement will become effective
upon the earlier of (i) the closing of the Transaction, or (ii) December 20,
2000 (the "Effective Date").

         2. Consulting Services. (a) The consulting relationship shall commence
on the day immediately following the Effective Date and ending on December 31,
2003 (the "Consulting Period"). During the Consulting Period, the Company shall
retain the Executive as a consultant, and the Executive shall perform and
discharge well and faithfully for the Company and its subsidiaries, such
consulting services as may be requested from time to time by the Board of
Directors of the Company. Notwithstanding the foregoing, it is understood and
agreed that the Executive will be engaging in other activities unrelated to the
Company and any request by the Company for services by the Executive will give
due consideration to the Executive's other commitments.

              (b) It is agreed that during the Consulting Period the Executive
shall be an independent contractor, shall not be an employee, servant, agent,
partner or joint venturer of the Company or any of its subsidiaries, officers,
directors or employees, and shall have no authority to assume or create any
obligation or liability, express or implied, on behalf of the Company or its
subsidiaries, or in its or their name or to bind them in any manner

<PAGE>

whatsoever; provided, however, that to the extent payments pursuant to paragraph
3 are made to the Executive with no payment by the Employer of the Employer's
portion of social security taxes, the Company shall increase the payments under
paragraph 3 by an amount, equal to one-half of Executive's self-employment tax
on a fully grossed-up basis.

         3. Consulting Fees. (a) In full satisfaction for any and all services
rendered and covenants made by the Executive hereunder, and in full payment for
the covenant of Executive set forth in Section 6 below, the Company shall pay
the Executive $1,500,000, payable in three equal installments of $500,000 each
on January 4, 2001, January 4, 2002 and January 4, 2003. If after the Effective
Date the Executive dies or becomes disabled, then all consulting payments
hereunder scheduled for payment on or following the date of death or the date of
disability shall cease and any obligation to provide Employment or Consulting
Services thereafter shall cease. For the purposes of this Agreement, the date of
disability is the date the Executive first perfects his eligibility (or the date
he would have first perfected such eligibility, but for his termination of
employment with the Company or his loss of coverage under the Company's long
term disability program) for extended long term disability benefits requiring
him to be unable to perform any gainful occupation pursuant to the Company's
long term disability program.

              (b) If at anytime after the Transaction closes and during the
Consulting Period there occurs a subsequent Change in Control, then promptly
following such Change in Control the Company (or its successors or assigns)
shall pay to the Executive in a single lump sum the present value (utilizing an
8% discount factor compounded annually) of all the cash payments then not yet
paid pursuant to paragraph 3(a), and all other provisions of this Agreement
shall thereupon continue in full force and effect. For the purposes hereof,
"Change in Control" means the occurrence, following the date of the Transaction,
of an event as a result of which a "person" or "group of persons", as such terms
are used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as
amended, who are not affiliated with or are not controlled by Heartland
Industrial Partners, L.P., directly or indirectly are the "beneficial owners"
(as defined in Rule 13d-3 under the Exchange Act) or have the right to acquire
such beneficial ownership (whether or not such right is exercisable immediately,
with the passage of time or subject to any condition) of voting securities
representing 50% or more of the combined voting power of all outstanding voting
securities of the Company.

              (c) The Executive acknowledges that his employment will terminate
as of the Effective Date and he will cease to be an active participant under the
benefit plans of the Company on such date pursuant to the terms of the
applicable benefit plans, and no additional Company-provided benefits shall
accrue to him after such date, other than salary earned through the Effective
Date which has not yet been paid. Nothing contained herein shall restrict the
Executive's receipt of benefits under the Company's employee fringe benefit
programs accrued during the Executive's employment with the Company.

                                        2
<PAGE>

         4. Options and Awards. All of the restricted stock awards and options
heretofore granted to the Executive under the Company's restricted stock award
and option plans will be treated in the same manner as the awards and options of
other employees of the Company in the Transaction who continue as employees of
the Company.

         5. Gross-Up. In the event that, as a result of the payment to the
Executive under paragraph 3 hereof and/or the vesting of stock awards or options
in connection with the Transaction, Executive becomes subject to excise tax (the
"Excise Tax") under Section 4999 of the Internal Revenue Code of 1986, as
amended (the "Code"), the Company shall pay to Executive as an additional
payment an amount (the "Gross-Up Payment") equal to an amount which, after
payment by Executive of all taxes (including any federal, state and local income
tax and excise tax upon such amount) would allow the Executive to retain an
amount equal to the Excise Tax, unless, if the reduction of the payments under
paragraph 3(a) to Executive by no more than 5% would avoid the imposition of
Excise Tax, then the Company shall so reduce such payments to Executive and no
Gross-Up Payment will be made.

         For purposes of determining whether Executive will be subject to the
Excise Tax and the amount of such Excise Tax, the following criteria shall
apply:

         (a) All determinations required to be made under this Section 5 shall
be made by the Company's independent auditors (the "Accounting Firm"), which
shall provide detailed supporting calculations to both the Company and Executive
within 15 business days after the Effective Date or such earlier time as is
requested by the Company provided that any determination that an Excise Tax is
payable by Executive shall be made on the basis of substantial authority. If the
Accounting Firm determines that no Excise Tax is payable by Executive, it shall
furnish Executive with a written opinion that Executive has substantial
authority not to record any Excise Tax on his federal income tax return. Any
determination by the Accounting Firm meeting the requirements of this Section
5(a) shall, subject to possible adjustment as set forth in Section 5(c) below,
be binding upon the Company and Executive.

         (b) The value of any non-cash benefits or any deferred payment or
benefit shall be determined by the Accounting Firm in accordance with the
principles of Sections 280G(d)(3) and (4) of the Code. For purposes of
determining the amount of the Gross-Up Payment, Executive shall be deemed to pay
federal income taxes at the highest marginal rate of federal income taxation in
the calendar year in which the Gross-Up Payment is to be made and state and
local income taxes at the highest marginal rate of taxation in the state and
locality of Executive's residence on the date on which the Excise Tax is
incurred, net of the maximum reduction in federal income taxes which could be
obtained from deduction of such state and local taxes.

                                       3
<PAGE>

         (c) In the event that the Excise Tax is subsequently determined to be
less than the amount taken into account hereunder, Executive shall repay to the
Company, at the time that the amount of such reduction in Excise Tax is finally
determined, the portion of the Gross-Up Payment attributable to such reduction
(plus that portion of the Gross-Up Payment attributable to the Excise Tax and
federal, state, and local income tax deduction) plus interest on the amount of
such repayment at the rate provided in Section 1274(b)(2)(B) of the Code. In the
event that the Excise Tax is determined to exceed the amount taken into account
hereunder (including by reason of any payment the existence or amount of which
cannot be determined at the time of the Gross-Up Payment), the Company shall
make an additional payment in respect of such excess at the time that the amount
of such excess finally is determined. In the case of any payment that the
Company is required to make to Executive pursuant to the preceding sentence (a
"Later Payment"), the Company shall also pay to Executive an additional amount
such that after payment by Executive of all of Executive's applicable federal,
state and local taxes, including any interest and penalties assessed by any
taxing authority, on such additional amount, Executive will retain an amount
equal to the total of Executive's applicable federal, state and local taxes,
including any interest and penalties assessed by any taxing authority, arising
due to the Later Payment. Executive and the Company each shall reasonably
cooperate with the other in connection with any administrative or judicial
proceedings concerning the existence or amount of liability for Excise Tax.

         Notwithstanding any provision of this Agreement to the contrary,
Executive shall pay his ordinary federal, state and local income taxes to which
he is subject as a result of the Transaction (including but not limited to the
accelerated vesting of stock options).

         6. Non-Competition; Non-Solicitation; Confidentiality. (a) Executive
acknowledges and recognizes the highly competitive nature of the business of the
Company and accordingly agrees that, in consideration of this Agreement, the
rights conferred hereunder, and the payments hereunder, during the Non-Compete
Term, Executive will not engage, either directly or indirectly, as an employee,
consultant or independent contractor, or as a principal for his own account or
jointly with others, or as a stockholder in any corporation or joint stock
association which designs, develops, manufactures, distributes, sells or markets
the type of products or services sold, distributed or provided by the Company or
its subsidiaries during the two year period prior to the Effective Date (the
"Business"); provided, that nothing herein shall prevent Executive from owning,
directly or indirectly, not more than 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.

         (b) During the period from the date of this Agreement until December
31, 2003 ("Non-Compete Term"), Executive will not (i) directly or indirectly
employ or solicit, or receive or accept the performance of services by, any
active employee of the 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 (ii)
solicit for business (relating to the Business) any person who is a customer or
former customer of the Company or any of its subsidiaries,

                                       4
<PAGE>

unless such person shall have ceased to have been such a customer for a period
of at least six months.

         (c) Executive will not at any time disclose or use for his 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 the Company and any of its subsidiaries, any trade
secrets, information, data, or other confidential 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 the Company generally, or of any subsidiary of the
Company, unless 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 the Company. The preceding sentence of this
sub-clause (c) shall not apply to information which is not unique to the 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 within 10 days
after the Effective Date, he will return to the 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 the Company
and its subsidiaries, except that he may retain personal notes, notebooks and
diaries. Executive further agrees that he will not retain or use for his account
at any time any trade names, trademark or other proprietary business designation
used or owned in connection with the business of the Company or its
subsidiaries.

         (d) It is expressly understood and agreed that although Executive and
the Company consider the restrictions contained in this Section 6 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.

         7. Remedies. Executive acknowledges and agrees that the Company's
remedies at law for a breach or threatened breach of any of the provisions of
Section 6 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, the 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.

                                       5
<PAGE>

         8. No Disparagement. Executive agrees not to criticize, disparage or
otherwise demean in any way the Company, any of its subsidiaries or their
respective products, officers, directors or employees. Likewise, the Company
agrees not to criticize, discourage or otherwise demean in any way the
Executive.

         9. RELEASE. IN CONSIDERATION OF THE PAYMENTS TO BE MADE AND BENEFITS
PROVIDED BY THE COMPANY AND OTHER AGREEMENTS HEREUNDER, EXECUTIVE ON EXECUTIVE'S
OWN BEHALF AND ON BEHALF OF EXECUTIVE'S HEIRS, EXECUTORS, AGENTS, SUCCESSORS AND
ASSIGNS, RELEASES AND FOREVER DISCHARGES THE COMPANY AND ITS SUBSIDIARIES AND

DISCRIMINATION, CLAIMS RELATING TO THE TERMINATION OF EMPLOYMENT AS REFERRED TO

Company of breach of Sections 6 or 8) in any way relating to this Agreement or
for the breach thereof to the extent such claims are covered by the CDRP, and
the Executive agrees not to pursue any such claims through a court or a jury.
