Participating Shareholders shall, for a period of ten (10) days after receipt of

period pay to such Participating Shareholders the Earn-Out Payments in
proportion to the Conversion Share Equivalent and Earn-Out Percentage

hereto. If the Participating Majority shall have requested the right to review
such calculation, the Participating Majority shall have the right to retain, at
the expense of the Participating Majority, a nationally recognized accounting
firm to review the calculation of the EBT prepared by GBB. For a period of not
more than thirty (30) days following the date of the Participating Majority's
request to review such calculation, GBB shall, upon reasonable notice and at
reasonable times without significant disruption to the business of the Matsco
Operating Unit, give the Participating Majority and the accounting firm retained
by the Participating Majority reasonable access to the work papers of the
accounting firm retained by GBB, to all offices and other facilities of the
Matsco Operating Unit and to all books and records necessary to review the
calculation of the EBT and will cause the officers of the Matsco Operating Unit
to furnish to the Participating Majority such financial and other operational
data and other information as the Participating Majority may reasonably request
in connection with such review. If, after conducting such review, the
Participating Majority advises GBB in writing no later than five (5) days after
the end of the thirty day period that it disputes the calculation of EBT
prepared by GBB, then the dispute shall be resolved as follows:

                  (i) First, the accounting firms retained by GBB and the
Participating Majority shall attempt to resolve the discrepancies in their
respective

                                       11

on which the Participating Majority notifies GBB of its dispute of GBB
calculation of the EBT;

                  (ii) Second, if the accounting firms can not resolve the
discrepancies in their calculations, then GBB and the Participating Majority
shall submit the dispute to binding arbitration in accordance with Section

regarding the calculation of EBT, then such dispute shall be resolved by

judge or justice. If GBB and the Participating Majority are unable to agree on a
retired judge or justice, each party will name one retired judge or justice and
the two persons so named will select a neutral judge or justice who will act as
the sole arbitrator. The parties shall be entitled to take discovery in
accordance with the provisions of the California Code of Civil Procedure, but
either party may request that the arbitrator limit the amount or scope of
discovery and, in determining whether to do so, the arbitrator shall balance the
need for the discovery against the parties' mutual desire to resolve disputes
expeditiously and inexpensively. The prevailing party shall be entitled to
recover all reasonable attorneys' fees, expert fees, expenses, and costs
(whether or not such fees, expenses, and costs are recoverable pursuant to the
California Code of Civil Procedure).

             (d) Until Marshall has received the entire $600,000 payment
referenced in Section 2.3(a), Marshall shall be entitled to the rights of a
Participating Shareholder under Sections 2.3(b) and (c).

         2.4 Holdback Funds. The Holdback Funds shall be withheld by GBB and
             --------------
shall earn interest at the fixed rate of 7.50% per annum and, to the extent the
Holdback Funds are not used and are determined by GBB in good faith and in its
commercially reasonable discretion to no longer be required for the resolution
of any Material Contingency, shall be released by GBB and delivered to the
Participating Shareholders together with accrued interest on the Holdback Funds
in proportion to the Conversion Share Equivalents and Earn Out Percentage
respectively held by the Participating Shareholders as set forth on Exhibit A
hereto as follows:

         .        one-third (1/3) of the remaining Holdback Funds plus accrued
                  interest on the entire balance of the Holdback Funds on the
                  first anniversary of the Closing Date;

         .        one-half (1/2) of the remaining Holdback Funds plus accrued
                  interest on the remaining balance of the Holdback Funds on the
                  second anniversary of the Closing Date; and

         .        the balance of the Holdback Funds plus accrued interest on the
                  remaining balance of the Holdback Funds on the third
                  anniversary of the Closing Date;

                                       12
<PAGE>

provided  that any  payments to Marshall  required by Section 2.3 shall first be
subtracted and paid to Marshall on the dates specified in this Section 2.4.

          Nothing in this Section 2.4 shall limit the right of GBB to seek
indemnification from the Participating Shareholders to the extent permitted in
Article 15 of this Agreement; provided that indemnity may only be sought by GBB
for a Material Contingency to the extent the Loss (as defined in Section 15.2)
incurred by GBB on all Material Contingencies in the aggregate shall exceed the
lesser of $900,000 or the remaining amount of Holdback Funds. The balance of any
Holdback Funds determined by GBB as provided herein as required for the
resolution of the Material Contingencies shall be released, together with
accrued interest, promptly when no longer required to resolve any Material
Contingency.

      2.5 Spencer Consideration. Payment of the First Retention Payment (as that
          ---------------------
term is defined in the Spencer Agreement) as full consideration for the shares
of Matsco Stock held by Harold Spencer shall be made as provided in a letter
agreement (the "Spencer Agreement") in the form of Exhibit "F" hereto. Nothing
in this Section 2.5 or in the Spencer Agreement shall limit the right of GBB to
seek indemnification from Harold Spencer to the extent permitted in Article 15
of this Agreement after the First Retention Payment has been made to Harold
Spencer, it being agreed that the Second Retention Payment (as that term is
defined in the Spencer Agreement) shall not be deemed to be consideration
received by Harold Spencer as consideration for shares of Matsco Stock held by
Harold Spencer and, therefore, shall not be subject to payment by Harold Spencer
to GBB in connection with any indemnification obligation, if any, of the Matsco
Shareholders pursuant to the terms of this Agreement.

      2.6 Vesting. Notwithstanding the requirements in Section 2.3 regarding the
          -------
required employment of a Participating Shareholder (other than The Timothy
Shieman Trust) by the Matsco Operating Unit during a Fiscal Year or whether the
Matsco Operating Unit EBT is equal to or greater than the Earn-Out Targets or a
portion thereof set forth in Exhibit B, if (i) a Participating Shareholder is no
longer employed by the Matsco Operating Unit throughout the entire prior Fiscal
Year as a result of death, disability or involuntary termination other than for
"cause" or (ii) a Change in Control of GBB occurs, then that Participating
Shareholder (in the case of death, disability or involuntary termination) or all
Participating Shareholders (in the case of a Change in Control of GBB) shall be
entitled to receive its Conversion Share Equivalent and Earn Out Percentage of
the entire Earn-Out Payment for each and all of the remaining Fiscal Years that
the Earn-Out Payment is payable pursuant to Section 2.3 as if the Matsco
Operating Unit shall have achieved an EBT equal to or greater than the Earn-Out
Targets as set forth on Exhibit B hereto for each such Fiscal Year, and said
amounts shall be paid by GBB or its successor on or before March 31 in each
Fiscal Year as otherwise provided in Section 2.3. In such event and subject to
Section 2.7, the amount of GBB Common Stock to be issued for 50% of the future
Earn-Out Payments will instead be calculated using the average price of GBB
stock for the most recent Fiscal Year and such GBB Common Stock shall then be
issued and held by GBB or its successors in escrow until the March 31 payment
date in each Fiscal Year whereupon the determined amount of GBB Common Stock for
that Fiscal Year shall be delivered by GBB.

      2.7 GBB Common Stock.

         payment of fifty percent (50%) of Earn-Out Payments in GBB Common
         Stock, GBB shall not be deemed to have offered or agreed to issue any
         GBB Common Stock as provided in Section 2.3 to any Matsco Shareholder
         and 100% of each Earn-Out Payment shall be paid entirely in cash
         unless:

                           (i) A permit (the "Permit") has been issued by the
                  Commissioner of Corporations of the State of California
                  pursuant to Section 25142 of the California Corporate
                  Securities Laws of 1968, as amended;

                           (ii) GBB determines at its option after receiving the
                  Permit and at the time Earn-Out Payments are payable as
                  provided in Section 2.3 to offer GBB Common Stock in lieu of
                  cash for up to 50% of such Earn-Out Payments, subject to the
                  provisions of Section 2.3, to the Matsco Shareholders eligible
                  to receive an Earn-Out Payment;

                           (iii) A Matsco Shareholder eligible to receive an
                  Earn-Out Payment elects to accept GBB's offer; and

                           (iv)  All documentation required by GBB in connection
                  with the issuance of the GBB Common Stock shall have been
                  completed, executed and delivered, including any investment
                  representations or affiliate's agreements as may be required.

                  (b) GBB agrees to use its best efforts to obtain the Permit.

                        AND THE INDEMNIFYING SHAREHOLDERS

         Matsco and each of the Indemnifying Shareholders, jointly and
severally, represent and warrant to GBB as follows:

Subsidiaries are qualified or licensed to do business in all jurisdictions in
which the scope of its business or the location of any of its properties in such
jurisdictions requires such licensing or qualification, except where the failure
to so qualify or to be so licensed would not have a Material Adverse Effect.
Matsco has furnished to GBB true and correct copies of its and each of the
Matsco Subsidiaries' articles of incorporation, bylaws, licenses and
qualifications in effect as of the date hereof.

         4.2 Capitalization.
             --------------

             As of the date of this Agreement, the authorized capital stock of
Matsco consists of 200,000 shares of Matsco Common Stock, $0.001 par value, of
which, on the date hereof, there are 5,200 shares issued and outstanding, and
10,000 shares of Matsco Preferred Stock, $0.001 par value, of which, on the date

and outstanding. All of the outstanding shares are duly authorized, validly
issued, fully paid and nonassessable and are owned of record, and in the
respective amounts, by the Matsco Shareholders as identified in Exhibit A

or with respect to the unissued shares of Matsco Stock, nor any securities
(other than the Matsco Preferred Stock) convertible into such stock, and Matsco
is not obligated to issue any additional shares of its common stock (other than
upon conversion of outstanding shares of the Matsco Preferred Stock), preferred
stock or any additional options, warrants or other rights in or with respect to
the unissued shares of such stock or any other securities convertible into such
stock.

         4.3 Subsidiaries. Except for the Matsco Subsidiaries and as set forth
             ------------
on the Matsco Investment Securities List, Matsco does not own, directly or
indirectly (except for shares and warrants of Carbide Tools for Industry
acquired as pledgee pursuant to loans or

                                       15
<PAGE>

upon acquisition in satisfaction of debt previously contracted), the outstanding
stock or equity or other voting interest in any corporation, partnership, joint
venture or other entity.

         4.4 Financial Statements. Matsco has previously furnished to GBB a copy
             --------------------
of the Financial Statements of Matsco. The Financial Statements of Matsco: (a)
present fairly the financial condition of Matsco as of the respective dates
indicated and its results of operations and changes in cash flows, for the
respective periods then ended, subject, in the case of the unaudited interim
financial statements, to normal recurring adjustments; and (b) have been
prepared in accordance with GAAP consistently applied (except as otherwise
indicated therein and that the unaudited Matsco Financial Statements do not
contain footnotes as required by GAAP).

         4.5 Reports and Filings. Except as set forth on a list furnished by
             -------------------
Matsco to GBB (the "Matsco Filings List") and since December 31, 1996, Matsco
and each of the Matsco Subsidiaries have filed all reports, returns,
registrations and statements (such reports and filings referred to as "Matsco
Filings"), together with any amendments required to be made with respect
thereto, that were required to be filed with the Commissioner, the Delaware
Secretary of State and any other applicable Governmental Entity, including
taxing authorities, except where the failure to file such reports, returns,
registrations or statements has not had and is not reasonably expected to have a
Material Adverse Effect. Except as disclosed in the Matsco Filings List, no
adverse administrative actions have been taken or orders issued in connection
with such Matsco Filings. As of their respective dates, each of such Matsco
Filings (a) complied in all material respects with all laws and regulations
enforced or promulgated by the Governmental Entity with which it was filed (or
was amended so as to be in compliance promptly following discovery of any such
noncompliance); and (b) did not contain any untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading. Any financial statement contained in any of such Matsco
Filings that was intended to present the financial position, results of
operations or cash flows of Matsco on a consolidated basis fairly presented the
financial position, results of operations or cash flows of Matsco on a
consolidated basis and was prepared in accordance with GAAP consistently
applied, except as stated therein, during the periods involved. Matsco has
furnished GBB with true and correct copies of all Matsco Filings filed by Matsco
since December 31, 1996.

Agreement and the consummation of the transactions contemplated hereby have been
duly and validly authorized by all necessary corporate action on the part of
Matsco, including the execution by all Matsco Shareholders of written consents
approving the transactions contemplated herein, and, assuming the accuracy of
the representations contained in Section 6.3 hereof, this Agreement is, upon due
execution and delivery by the respective parties hereto, a valid and binding
obligation of Matsco enforceable in accordance with its terms, except as the
enforceability thereof may be limited by bankruptcy, liquidation, receivership,
conservatorship, insolvency, moratorium or other similar laws affecting the
rights of creditors generally and by general equitable principles. Except as set
forth in a list furnished by Matsco to GBB (the "Matsco Conflicts and Consents
List"), neither the execution and delivery by

                                       16
<PAGE>

herein, nor compliance by Matsco with any of the provisions hereof, will: (a)
conflict with or result in a breach of any provision of its certificate of
incorporation, as amended, or bylaws, as amended; (b) constitute a breach of or
result in a default (or give rise to any rights of termination, cancellation or
acceleration, or any right to acquire any securities or assets) under any of the
terms, conditions or provisions of any material note, bond, mortgage, indenture,
franchise, license, permit, agreement or other instrument or obligation to which
Matsco or any of the Matsco Subsidiaries is a party, or by which Matsco or any

Governmental Entity having jurisdiction over any aspect of the business or
assets of Matsco or any of the Matsco Subsidiaries, and no consent of, approval
of or notice to any other Person, is required in connection with the execution
and delivery by Matsco of this Agreement or the consummation by Matsco of the
transactions contemplated hereby.

         4.7 Insurance. Matsco has the policies of insurance with respect to its
             ---------
and the Matsco Subsidiaries' assets and business against such casualties and
contingencies and in such amounts, types and forms as are set forth in a list
furnished by Matsco to GBB (the "Matsco Insurance List"). All such insurance
policies are in full force and effect. Except as set forth in the Matsco
Insurance List, no insurer under any such policy has canceled or indicated an
intention to cancel or not to renew any such policy or generally disclaimed
liability thereunder. Except as set forth in the Matsco Insurance List, Matsco
is not in default under any such policy and all material claims thereunder have
been filed in a timely fashion. Set forth in the Matsco Insurance List is a list
of all policies of insurance carried and owned by Matsco or any of the Matsco
Subsidiaries showing the name of the insurance company, the nature of the
coverage, the policy limit, the annual premiums and the expiration dates. There
has been furnished to GBB a copy of each such policy of insurance.

         4.8 Personal Property. Matsco and each of the Matsco Subsidiaries have
             -----------------
good and marketable title to all its material properties and assets (other than
real property) owned or stated to be owned by Matsco or any Matsco Subsidiary as
reflected on the Matsco Financial Statements as of December 31, 1999 and March
31, 2000 or acquired after that date free and clear of all Encumbrances except
(a) as disposed of in the ordinary course of business; (b) as set forth in the
Financial Statements of Matsco; (c) for Encumbrances for current taxes and
assessments not yet due and payable; (d) for Encumbrances incurred in the
ordinary course of business; (e) for Encumbrances that are not substantial in
character, amount or extent and that do not materially detract from the value,
or interfere with present use, of the property subject thereto or affected
thereby, or otherwise materially impair the conduct of business of Matsco; or
(f) as set forth in a list furnished by Matsco to GBB (the "Matsco Personal
Property List").

         4.9 Real Estate. Neither Matsco nor any Matsco Subsidiary owns any real
             -----------
property. Matsco has furnished GBB a list of all leaseholds and all other
interests in real property (other than security interests or liens in favor of
Matsco) owned by Matsco or any of

                                       17
<PAGE>

the Matsco Subsidiaries (the "Matsco Real Property List") as of March 31, 2000
or acquired after that date. Matsco or any of the Matsco Subsidiaries has valid
leasehold interests in the leaseholds, described in the Matsco Real Property
List, free and clear of all Encumbrances, except (a) for rights of lessors, co-
lessees or sublessee in such matters that are reflected in the lease; (b) for
current taxes not yet due and payable; (c) for Encumbrances of public record;
(d) for such Encumbrances, if any, as do not materially detract from the value
of or materially interfere with the present use of such property; and (e) as
described in the Matsco Real Property List. Matsco has furnished GBB with true
and correct copies of all leases included in the Matsco Real Property List, all
title insurance policies and all documents evidencing recordation of all
recordable interests in real property included in the Matsco Real Property List.

         4.10 Contingent Liabilities. Neither Matsco nor any Matsco Subsidiary
              ----------------------
has any liabilities or obligations, either accrued or contingent, and including
any obligation for known but unasserted claims, that are material to Matsco or
any Matsco Subsidiary on a consolidated basis and there is no private or
governmental suit, claim, action or proceeding pending, nor, to Matsco's
knowledge threatened or known but unasserted against Matsco, or any of the
Matsco Subsidiaries, or directors, officers or employees of Matsco or any of the
Matsco Subsidiaries relating to the performance of their duties in such
capacities or against or affecting any properties of Matsco or any of the Matsco
Subsidiaries which, if adversely determined, would have a Material Adverse
Effect, except for liabilities and obligations: (a) reflected, reserved for or
disclosed in the Financial Statements of Matsco; (b) incurred subsequent to
September 30, 1999 in the ordinary course of business; or (c) disclosed in a
list furnished by Matsco to GBB (the "Matsco Liabilities List") or on any other
Matsco List. To the knowledge of Matsco, there are no facts that would form the
valid basis for the assertion against it or any Matsco Subsidiary of any
liability, obligation or claim (including, without limitation, that of any
regulatory authority) that is likely to result in or cause a Material Adverse
Effect and is not fairly reflected in the Financial Statements of Matsco or
otherwise disclosed in this Agreement. The Material Liabilities list contains a
list of those certain contingent liabilities (the "Material Contingencies")
which the Indemnifying Shareholders and GBB agree may be resolved, if necessary,
by the use of the Holdback Funds and which shall be subject to the procedures
set forth in Section 15.3. Except as disclosed in the Matsco Liabilities List,
there are no judgments, decrees, stipulations or orders against Matsco or any of
the Matsco Subsidiaries or enjoining its directors, officers or employees in
respect of, or the effect of which is to prohibit, any business practice or the
acquisition of any property or the conduct of business in any area.

         4.11 Taxes. Except as set forth on the Matsco Tax List, Matsco and the
              -----
Matsco Subsidiaries have filed all federal and foreign income tax returns, all
state and local franchise and income tax, real and personal property tax, sales
and use tax, premium tax, excise tax and other tax returns required to be filed
and has paid all taxes, together with any interest and penalties owing in
connection therewith, shown on such returns to be due in respect of the periods
covered by such returns, other than taxes which are being contested in good
faith and for which adequate reserves have been established. Matsco has not
filed a consent pursuant to Section 341(f) of the Code. The tax and audit
positions taken by Matsco and the Matsco Subsidiaries in connection with the tax
returns described in the first sentence of this paragraph

                                       18
<PAGE>

were asserted in good faith. Matsco and the Matsco Subsidiaries have filed all
required payroll tax returns, have fulfilled all tax withholding obligations and
have paid over to the appropriate governmental authorities the proper amounts
with respect to the foregoing. Adequate provision has been made in the books and
records of Matsco and, to the extent required by GAAP, reflected in the
Financial Statements of Matsco, for all tax liabilities, including interest or
penalties, whether or not due and payable and whether or not disputed, with
respect to any and all federal, foreign, state and local taxes for the periods
covered by such financial statements and for all prior periods. Matsco has
furnished GBB a list (the "Matsco Tax List") of the federal tax returns of
Matsco and the Matsco Subsidiaries which have been duly filed with the IRS on or
after December 31, 1996. The Matsco Tax List also contains a complete list of
each year for which any federal, state, local or foreign tax authority has
obtained or has requested an extension of the statute of limitations from Matsco
and lists each tax case of Matsco currently pending in audit, at the
administrative appeals level or in litigation. The Matsco Tax List further lists
the date and issuing authority of each statutory notice of deficiency, notice of
proposed assessment and revenue agent's report issued to Matsco within the last
twelve (12) months. Except as set forth in the Matsco Tax List, neither the IRS
nor any foreign, state or local taxing authority has, during the past three (3)
years, examined or has informed Matsco that it is in the process of examining
any federal, foreign, state or local tax returns of Matsco. Neither the IRS nor
any foreign, state or local taxing authority is now asserting or, to the
knowledge of Matsco, threatening to assert any deficiency or claim for
additional taxes (or interest thereon or penalties in connection therewith)
except as set forth on the Matsco Tax List.

         4.12 Compliance with Laws and Regulations.
              ------------------------------------

              (a) Except as expressly set forth or limited in other

Matsco Subsidiaries is in default under or in breach of any provision of its
certificate or articles of incorporation, as amended, or bylaws, as amended, or
law, ordinance, rule or regulation promulgated by any Governmental Entity,
except for such defaults or breaches that would not have a Material Adverse
Effect.

              (b) The representations and warranties in this Section 4.12(b)
apply only to matters which would have a Material Adverse Effect. Without

above the surface of, or migrating to or from Matsco Property; (iv) neither

real property that is not in compliance with Environmental Regulations or which
has a leaking Tank or upon which there are Hazardous Materials on or migrating
to or from; (v) neither Matsco nor any of its Affiliates has been an "operator"
of any Matsco Property for purposes of establishing liability under the
Environmental Regulations; and (vi) without limiting Section 4.10 or the
foregoing representations and warranties contained in clauses (i) through (v),
as of the date of this Agreement, there is no claim, action, suit or proceeding,
or notice thereof, before any

                                       19
<PAGE>

Governmental Entity pending against Matsco or any of the Matsco Subsidiaries or
concerning property securing Matsco loans and there is no outstanding judgment,
order, writ, injunction, decree, or award against or affecting Matsco Property
or property securing Matsco loans, relating to the foregoing representations (i)
through (v), in each case the noncompliance with which, or the presence of which
would have a Material Adverse Effect. Anything herein to the contrary
notwithstanding, neither Matsco nor any Matsco Subsidiary shall be deemed to
have conducted, or be required to conduct, any investigations of any Matsco
Property covered by this Section 4.12(b).

              (c) No Phase I environmental assessments have been prepared by or
on behalf of Matsco or any of the Matsco Subsidiaries.

         4.13 Performance of Obligations. Except contracts or agreements

         4.19 Employee Benefit Plans.
              ----------------------

              (a) Matsco has previously furnished to GBB copies of each of its
and any Matsco Subsidiary's "employee benefit plan," as defined in Section 3(3)
of ERISA, which is subject to any provision of ERISA and covers any employee,
whether active or retired, of Matsco, together with all amendments thereto, all
related summary plan descriptions (to the extent one is required by law), the
most recent determination or opinion letter issued by the IRS for each such plan
that is intended to be qualified under Section 401(a) of the Code, and the
annual reports for the most recent three (3) years (Form 5500 including, if
applicable, Schedule B thereto) prepared in connection with each such plan. Such
plans are hereinafter referred to collectively as the "Employee Plans." Matsco
does not participate in an employee benefit pension plan that is a
"multiemployer plan" within the meaning of Section 3(37) of ERISA that would
subject Matsco to a material amount of liability with respect to any such plan.
Each Employee Plan which is intended to be qualified in form and operation under
Section 401(a) of the Code is so qualified and the associated trust for each
such Employee

                                       23
<PAGE>

Plan is exempt from tax under Section 501(a) of the Code. To the knowledge of
Matsco, no event has occurred that will subject such Employee Plans to tax under
Section 511 of the Code. All amendments required to be made on or before the
date hereof to bring each Employee Plan into conformity with all of the
applicable provisions of ERISA, the Code and all other applicable laws have been
made. Except as disclosed in a list furnished by Matsco to GBB (the "Matsco
Employee Plan List"), all Employee Plans were in effect for substantially all of
1998 and 1999, and there has been no amendment thereof (other than amendments
required to comply with applicable law or to maintain an Employee Plan's tax-
qualified status under Section 401(a) of the Code) or increase in the cost
thereof or benefits thereunder on or after January 1, 1998.

              (b) Matsco has previously made available to GBB copies or
descriptions of each plan or arrangement maintained or otherwise contributed to
by Matsco which is not an Employee Plan and which (exclusive of base salary and
base wages) provides for any form of current or deferred compensation, bonus,
stock option, profit sharing, benefit, retirement, incentive, group health or
insurance, welfare or similar plan or arrangement for the benefit of any
employee or class of employees, whether active or retired, of Matsco (such plans
and arrangements being collectively referred to herein as "Benefit
Arrangements"). Except as disclosed in the Matsco Employee Plan List hereto, all
Benefit Arrangements which are in effect were in effect for substantially all of
1998 and 1999. There has been no amendment thereof or increase in the cost
thereof or benefits payable thereunder since January 1, 1998. Except as set
forth in the Matsco Employee Plan List, there has been no material increase in
the compensation of or benefits payable to any senior executive employee of
Matsco since January 1, 1999, nor any employment, severance or similar contract
entered into with any such employee, nor any amendment to any such contract,
since January 1, 1999. There is no contract, agreement or benefit arrangement
covering any employee of Matsco which individually or collectively could give
rise to the payment of any amount which would constitute an "excess parachute
payment," as such term is defined in Section 280(G) of the Code.

              (c) To the knowledge of Matsco, with respect to all Employee Plans
and Benefit Arrangements, Matsco is in compliance with the requirements
prescribed by any and all statutes, governmental or court orders, or
governmental rules or regulations currently in effect, including but not limited
to ERISA and the Code, applicable to such plans or arrangements. All government
reports and filings required by law have been properly and timely filed and all
information required to be distributed to participants or beneficiaries has been
distributed with respect to each Employee Plan. Matsco has performed all of its
obligations under all such Employee Plans and Benefit Arrangements in all
material respects. There is no pending or, to the knowledge of Matsco,
threatened legal action, proceeding or investigation against or involving any
Employee Plan or Benefit Arrangement which could result in liability to such
Employee Plan. To Matsco's knowledge, no condition exists that could constitute
grounds for the termination of any Employee Plan under Section 4042 of ERISA; no
"prohibited transaction," as defined in Section 406 of ERISA and Section 4975 of
the Code and for which there is no applicable exception or exemption, has
occurred with respect to any Employee Plan, or any other employee benefit plan
maintained by Matsco which is covered by Title I of ERISA, which could subject
any person (other than a person for

                                       24
<PAGE>

whom Matsco is not directly or indirectly responsible) to liability under Title
I of ERISA or to the imposition of a tax under Section 4975 of the Code; nor has
any Employee Plan subject to Part III of Subtitle B of Title I of ERISA or
Section 412 of the Code, or both, incurred any "accumulated funding deficiency,"
as defined in Section 412 of the Code, whether or not waived; nor has Matsco
failed to make any contribution or pay any amount due and owing as required by
the terms of any Employee Plan or Benefit Arrangement. No "reportable event" as
defined in Title IV of ERISA has occurred with respect to any of the Employee
Plans. To the knowledge of Matsco, Matsco has not incurred nor expects to incur,
directly or indirectly, any liability under Title IV of ERISA arising in
connection with the termination of, or a complete or partial withdrawal from,
any plan covered or previously covered by Title IV of ERISA which could
constitute a liability of GBB or of any of its affiliates (including Matsco) at
or after the Closing Date.

              (d) Except for Scheduled Contracts set forth in the Matsco
Contract List or as set forth in the Matsco Employee Plan List, as the case may
be, each Employee Plan or Benefit Arrangement and each personal services
contract, fringe benefit, consulting contract or similar arrangement with or for
the benefit of any officer, director, employee or other person can be terminated
by Matsco within a period of thirty (30) days following the Closing Date,
without payment of any amount as a penalty, bonus, premium, severance pay or
other compensation for such termination.

              (e) All group health plans of Matsco have been operated in
compliance with the applicable group health plan continuation coverage
requirements of Section 4980B of the Code.

              -------

Agreement has been duly and validly authorized, executed and delivered on behalf
of Matsco, and constitutes

                                       47

(subject to standard exceptions of enforceability arising from the bankruptcy
laws and rules of equity) the valid and binding agreement of Matsco; provided
that no opinion shall be required as to Article 15, the Employment Agreements or
the Non-Compete Agreements.

         12.6  Marshall Agreements. The Marshall Agreements shall have been
               -------------------
terminated.

         12.7  Shieman Employment Agreement. The Shieman Employment Agreement
               ----------------------------
shall have been terminated without any payments which may be otherwise required
thereunder.

         12.8  Status of Litigation. The status of any litigation which is a
               --------------------
Material Contingency shall be acceptable to GBB in its commercially reasonable
discretion.

         12.9  Employee Benefit Plans. GBB shall have received satisfactory
               ----------------------
evidence that all of Matsco's employee benefit plans, programs and arrangements
have been treated as provided in Article 13 of this Agreement.

         12.10 Officers' Certificate. There shall have been delivered to GBB on
               ---------------------
the Closing Date a certificate executed by the Chief Executive Officer and Chief

Pre-Closing Transactions.


                                  ARTICLE XIII

                                EMPLOYEE BENEFITS

         13.1 Employee Benefits. Subject to ERISA, the Code and other applicable
              -----------------
law, GBB, in its sole discretion, may elect (i) to terminate the Matsco 401(k)
Plan or to discontinue contributions to the Matsco 401(k) Plan following the
Closing Date, (ii) to cause Matsco to terminate the Matsco 401(k) Plan or to
discontinue contributions to the Matsco 401(k) Plan prior to the Closing Date,
or (iii) to merge the Matsco 401(k) Plan with and into the GBB 401(k) Plan after
the Closing Date. In no event shall the Matsco 401(k) Plan be merged with and
into the GBB 401(k) Plan, however, unless GBB reasonably determines that: (i)
the Matsco 401(k) Plan is a qualified plan under Section 401(a) of the Code,
both as to the form of the Matsco 401(k) Plan and as to its operation; and (ii)
there are no facts in existence that would be reasonably likely to adversely
affect the qualified status of the Matsco 401(k) Plan. If GBB determines that
the Matsco 401(k) Plan is to be terminated prior to the Closing Date, whereupon
Matsco agrees to use its best efforts to (i) terminate the Matsco 401(k) Plan
prior to the Closing Date, (ii) amend the Matsco 401(k) Plan prior to the
Closing Date to the extent necessary to maintain its tax-qualified status under
Section 401(a) of the Code on termination, and (iii) apply as soon as possible
for an IRS determination that the Matsco 401(k) Plan continues to be qualified
upon termination. Upon the issuance of such an IRS determination, GBB shall
cause the GBB 401(k) Plan to accept transfer of the accounts of the Matsco
401(k) Plan which cannot, without adversely affecting the tax-qualified status
of the Matsco 401(k)

                                       48
<PAGE>

Plan, be distributed to participants because of the "successor plan" rule of
Section 401(k)(10)(A)(i) of the Code.

         As soon as practicable after the Closing Date, all other Employee Plans
will be discontinued or merged into GBB plans, in the discretion of GBB, and
employees of Matsco shall become eligible for the employee benefit plans of GBB
on the same terms as such plans and benefits are generally offered from time to
time to employees of GBB and its subsidiaries in comparable positions with GBB
or its subsidiaries. For purposes of determining such employment eligibility and
vesting under the employee benefit plans of GBB, GBB shall recognize such
employees' years of service with Matsco beginning on the date such employees
commenced employment with Matsco through the Closing Date.

                                  ARTICLE XIV

                                  TERMINATION

performance or satisfaction of such covenant or agreement (provided that such
breach has not been waived by Matsco or cured by GBB, as the case may be, prior
to expiration of such ten (10) day period);

             (c) By GBB immediately upon expiration of ten (10) days from
delivery of written
notice by GBB to Matsco of  Matsco's  or the Matsco  Shareholders'  breach of or
failure to satisfy any covenant or  agreement  contained  herein  resulting in a

the  performance or  satisfaction  of such covenant or agreement  (provided that
such breach has not been  waived by GBB or cured by Matsco,  as the case may be,
prior to expiration of such ten-day period;

             (d) By Matsco or GBB upon the expiration of thirty (30) days after
any Governmental Entity denies or refuses to grant any approval, consent or
authorization required to be obtained in order to consummate the transactions
contemplated by this Agreement;

             (e) By Matsco or GBB immediately if any conditions set forth in
Article 10 shall not have been met by October 31, 2000;

             (f) By Matsco immediately if any of the conditions set forth in
Article 11 shall not have been met, or by GBB if any of the conditions set forth

<PAGE>

             (g) By GBB immediately if Matsco has taken or failed to take action
in breach of Section 7.1(n).

         14.2 Effect of Termination. In the event of termination of this
              ---------------------
Agreement by either Matsco or GBB as provided in Section 14.1, neither GBB, nor
Matsco nor the Matsco Shareholders shall have any further obligation or
liability to the other parties hereunder except (i) with respect to the last
sentence of each of Section 7.3 and 8.3 and (ii) with respect to Section 14.3,
to the extent that such termination results from such party's material breach of
the representations and warranties made by it, or material breach in the
performance of any of its covenants, agreements or obligations hereunder.

         14.3 Expenses.
              --------

             (a) GBB hereby agrees that if this Agreement is terminated by
Matsco pursuant to Section 14.1(b), GBB shall promptly, and in any event within
ten (10) days after such termination, pay Matsco all Expenses (as defined in
Section 14.3(e) below) of Matsco, but not to exceed $200,000.

             (b) Matsco hereby agrees that if the Agreement is terminated by GBB
pursuant to Section 14.1(c) or (g), Matsco shall promptly, and in any event
within ten (10) days after such termination, pay GBB all Expenses of GBB, but
not to exceed $500,000.

             (c) Except as otherwise provided herein, all Expenses incurred by
GBB, Matsco or the Matsco Shareholders in connection with or related to the
authorization, preparation and execution of this Agreement, the other
transaction documents and all other matters related to the closing of the
transactions contemplated hereby, including, without limiting the generality of
the foregoing, all fees and expenses of agents, representatives, counsel,
investment bankers and accountants employed by either such party or its
affiliates, shall be borne solely and entirely by the party which has incurred
the same.

             (d) GBB, Matsco and the Matsco Shareholders agree that,
notwithstanding anything to the contrary in this Agreement, in the event this
Agreement is terminated solely as a result of a failure of a condition, which
failure is due to a natural disaster or other act of God or an act of war, and
provided neither party has materially failed to observe the obligations of such
party under this Agreement, neither party shall be obligated to pay to the other
party to this Agreement any Expenses or otherwise be liable hereunder.

             (e) "Expenses" as used in this Agreement shall include all
reasonable out-of-pocket expenses (including all reasonable fees and expenses of
attorneys, accountants, investment bankers, experts and consultants to the party
and its affiliates) incurred by the party or on its behalf in connection with
the consummation of the transactions contemplated by this Agreement.

                      SURVIVAL; INDEMNIFICATION; RELEASE

                                       50
<PAGE>

         15.1 Survival.
              --------

             (a) Each representation, warranty, covenant and agreement of Matsco
and the Matsco Shareholders contained in this Agreement shall survive the
execution and delivery of this Agreement and the Closing and shall thereafter
terminate and expire on the eighteenth (18th) month anniversary of the Closing
Date, provided that the representations in Section 4.11 shall terminate and
expire on the Thirty-sixth (36th) month anniversary of the Closing Date.
Notwithstanding anything else contained in this Section 15.1(a), the
representations and warranties that are referenced in this Section 15.1(a) shall
not terminate and expire if, on or before the termination and expiration date
provided for therein, GBB or any of its Affiliates has delivered to the Matsco
Shareholders a written notice of a claim with respect to such representations
and warranties. The Material Contingencies identified in the Matsco Liabilities
List are subject to indemnification as provided in this Article notwithstanding
any disclosure of any Material Contingency on any Matsco List.

             (b) Each representation, warranty, covenant and agreement of GBB
contained in this Agreement shall survive the execution and delivery of this
Agreement and the Closing and shall thereafter terminate and expire on the
eighteenth (18th) month anniversary of the Closing Date except that the
covenants of GBB in Article 2 and Sections 8.7, 8.8 and 8.9 shall survive the
execution and delivery of this Agreement and the Closing and shall not terminate
or expire. Notwithstanding anything else contained in this Section 15.1(b), the
representations and warranties referenced in this Section 15.1(b) shall not
terminate and expire if, on or before the termination and expiration date
provided for herein, the Matsco Shareholders or any of their Affiliates has
delivered to GBB a written notice of a claim with respect to such
representations and warranties.

         15.2 Indemnification.
              ---------------

             (a) Each of the Indemnifying Shareholders shall indemnify GBB and
its Affiliates against, and shall hold each of them harmless from, any and all
cost, claims, damage, loss, liability and expense (including, without
limitation, reasonable expenses of investigation and reasonable attorneys' fees
and expenses in connection with any action, suit or proceeding) (collectively,
and after subtracting the amount of any insurance proceeds recoverable with
respect thereto "Loss") incurred or suffered by GBB or any of its Affiliates
arising out of any misrepresentation or breach of any representation, warranty,
covenant or agreement made or to be performed by Matsco or the Matsco
Shareholders pursuant to this Agreement (other than with respect to any
misrepresentation or breach of any representation or warranty by Marshall in
Article 5 with respect to Marshall or any breach of covenant or agreement by
Marshall) or incurred or suffered by GBB in the resolution of any Material
Contingency, and Marshall shall indemnify GBB and its Affiliates against, and
shall hold each of them harmless from, any and all Losses incurred or suffered
by GBB or any of its Affiliates arising out of any misrepresentation or breach
of any representation or warranty by Marshall in Article 5 with respect to
Marshall or any breach of covenant or agreement by Marshall; provided, however,
that the Matsco Shareholders shall only be required to indemnify GBB and its
Affiliates if, on a cumulative and aggregate basis, the amount of Loss incurred
by GBB and its Affiliates exceeds the amount of Seventy-Five Thousand Dollars
($75,000). However,

                                       51
<PAGE>

if the cumulative and aggregate amount of such Loss exceeds Seventy-Five
Thousand Dollars ($75,000), all of the Loss shall be subject to indemnification
hereunder by the Matsco Shareholders. Notwithstanding the foregoing, the
aggregate liability of the Matsco Shareholders under this Section 15.2(a) shall
not exceed $1.25 million. Notwithstanding the foregoing, the obligations of the
Indemnifying Shareholders to indemnify GBB for a Loss resulting from a breach of
their representations and warranties (other than with respect to the breach of
the representation and warranty of Marshall in Section 5.6 with respect to
shares of Matsco Stock held by Marshall) contained in Sections 4.2 and 5.6 and
Marshall's obligation to indemnify GBB for a Loss resulting from a breach of the
representation and warranty of Marshall in Section 5.6 with respect to shares of
Matsco Stock held by Marshall, shall not be subject to the foregoing limitation
on liability but may not exceed the aggregate consideration actually received by
the Matsco Shareholders in connection with the transactions contemplated herein.
Anything herein to the contrary notwithstanding, the maximum amount GBB may
recover from a Matsco Shareholder as a result of a Loss hereunder shall not in
the aggregate exceed that Matsco Shareholder's pro rata portion of such Loss. A
Matsco Shareholder's "pro rata portion" of a Loss shall be determined by
multiplying (i) the amount of the Loss times (ii) a fraction the numerator of
which is aggregate amount of the consideration actually received by that Matsco
Shareholder in connection with the transactions contemplated hereby and the
denominator of which is the aggregate amount of the consideration actually
received by all Matsco Shareholders in connection with the transactions
contemplated hereby; provided, that (a) Marshall shall not be obligated to pay
for any Loss resulting from a breach of any representation, warranty, covenant
or agreement of the Indemnifying Shareholders, and (b) the Indemnifying
Shareholders shall not be obligated to pay for any Loss resulting from a breach
of the representation and warranty of Marshall in Article 5 with respect to
Marshall, or the breach of any covenant or agreement of Marshall.

             (b) GBB shall indemnify each of the Matsco Shareholders against,
and shall hold each of them harmless from, any and all Loss incurred or suffered
by any of them arising out of any misrepresentation or breach, or any allegation
thereof, of any representation, warranty, covenant or agreement made or to be
performed by GBB or any of its Affiliates pursuant to this Agreement; provided,
however, that GBB shall only be required to indemnify the Matsco Shareholders
if, on a cumulative and aggregate basis, the amount of Loss incurred by the
Matsco Shareholders exceeds Seventy-Five Thousand Dollars ($75,000). However, if
the cumulative and aggregate amount of such Loss exceeds Seventy-Five Thousand
Dollars ($75,000), all of the Loss shall be subject to indemnification hereunder
by GBB. Notwithstanding the foregoing, GBB's obligation to indemnify the Matsco
Shareholders for a Loss resulting from a breach of its representations and
warranties contained in Article 2 and Sections 8.7 and 8.9 shall not be subject
to the foregoing limitation on liability.

         15.3 Procedures. The party seeking indemnification under Section 15.2
              ----------
(the "Indemnified Party") agrees to give prompt notice to the party against whom
indemnity is sought (the "Indemnifying Party") of the assertion of any claim, or
the commencement of any suit, action or proceeding in respect of which indemnity
may be sought under Section 15.2; provided that the failure to give such notice
shall not limit the Indemnified Party's right to indemnification hereunder
except to the extent that the Indemnifying Party is materially prejudiced
thereby. The Indemnifying Party shall assume control of the defense of any such

                                       52
<PAGE>

suit, action or proceeding and the Indemnified Party may participate in the
defense of any such suit, action or proceeding at its own expense. The
Indemnifying Party shall not be liable under Section 15.2 for any settlement
effected without its consent of any claim, litigation or proceeding in respect
of which indemnity may be sought hereunder; provided, however, that consent to
settlement shall not be unreasonably withheld or delayed. In any such
suit, action or proceeding, the Indemnified Party shall have the right to retain
its own counsel, but the fees and expenses of such counsel shall be at the
expense of such Indemnified Party unless (i) the Indemnifying Party has agreed
to pay such fees and expenses, (ii) the Indemnifying Party has failed to assume
the defense of such suit, action or proceeding or to employ counsel reasonably
satisfactory to the Indemnified Party, or (iii) in the reasonable judgment of
such Indemnified Party representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them, in
any which case, if the Indemnified Party notifies the Indemnifying Party in
writing that the Indemnified Party elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense of such suit, action or proceeding on behalf of the
Indemnified Party. The Indemnifying Party shall not be liable for the fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) at any time for all the Indemnified Parties.

         15.4 Release.
              -------

             (a) In consideration of the payment of the Purchase Price to the
Matsco Shareholders at the Closing, effective as of the Closing Date, the Matsco
Shareholders shall release and discharge GBB, Matsco and their Affiliates, and
each of their respective shareholders, officers, directors, employees, agents
and attorneys, from any and all claims, contentions, demands, causes of action
at law or in equity, debts, liens, agreements, notes, obligations or liabilities
of any nature, character or description whatsoever, whether known or unknown,
which the Matsco Shareholders may now or hereafter have against Matsco by reason
of any matter, event, thing or state of facts occurring, arising, done, omitted
or suffered to be done prior to the Closing Date; provided, that nothing in this
section shall release or discharge GBB, Matsco or their Affiliates, or any of
their respective shareholders, officers, directors, employees, agents or
attorneys, (i) from any claims arising from or in connection with this Agreement
or any agreement entered into in connection herewith, including any claims
arising from a breach of any representations, warranties or covenants contained
herein or therein, (ii) from any obligations or indebtedness owed by Matsco to
any Matsco Shareholder, including any indebtedness in connection with any loans
made by such Matsco Shareholder to Matsco, (iii) to the extent any such claim
by, actions by or rights of the Matsco Shareholder are covered by insurance
which was in effect at the time the event giving rise to such claim, action or
right occurred; (iv) from any obligation relating to compensation (including
accrued vacation) due and payable to such Matsco Shareholder in such Matsco
Shareholder's capacity as an employee of Matsco; or (v) from any claims arising
from or in connection with the guaranties described in Section 8.7 of this
Agreement.

             (b) In consideration of the Matsco Shareholders entering into the
transactions contemplated hereby, effective as of the Closing Date, GBB (on
behalf of itself and its Affiliates) and Matsco (on behalf of itself and its
Affiliates) shall release and discharge

                                       53
<PAGE>

the Matsco Shareholders and their Affiliates, and each of their respective
shareholders, officers, directors, employees, agents and attorneys, from any and
all claims, contentions, demands, causes of action at law or in equity, debts,
liens, agreements, notes, obligations or liabilities of any nature, character or
description whatsoever, whether known or unknown, which GBB, any of GBB's
Affiliates, Matsco or any of Matsco's Affiliates may now or hereafter have
against any of the Matsco Shareholders by reason of any matter, event, thing or
state of facts occurring, arising, done, omitted or suffered to be done prior to
the Closing Date; provided, that nothing in this section shall release or
discharge the Matsco Shareholders or their Affiliates, or any of their
respective shareholders, officers, directors, employees, agents or attorneys,
(i) from any claims arising from or in connection with this Agreement or any
agreement entered into in connection herewith, including any claims arising from
a breach of any representations, warranties or covenants contained herein or
therein, or (ii) from any indebtedness for money borrowed or owed by any Matsco
Shareholder to Matsco.

             (c) The Matsco Shareholders, GBB (on behalf of itself and its
Affiliates) and Matsco (on behalf of itself and its Affiliates) hereby
acknowledge and represent that they have been advised by their respective
attorneys of record, and are familiar with, Section 1542 of the Civil Code of
the State of California, which presently provides as follows:

             "A general release does not extend to claims which the creditor
             does not know or suspect to exist in his favor at the time of
             executing the release, which if known by him must have materially
             affected his settlement with the debtor."

             The  Matsco  Shareholders,  GBB (on  behalf of itself  and its
Affiliates) and Matsco (on behalf of itself and its Affiliates) hereby waive and
relinquish  any and all rights and benefits under Section 1542 of the Civil Code
as now  worded  and as it may  from  time  to  time  hereafter  be  amended,  in
connection with the releases in this Section 15.4.

              -------------
not benefit or create any right or cause of action to any person other than

         16.6 Knowledge. Except as specifically otherwise indicated or qualified
              ---------
elsewhere in this Agreement (including, but not limited to, by the use of the
word "actual"), whenever any statement herein or in any list, certificate or

made such statement only after conducting an investigation, if commercially
reasonable to do so under the circumstances, of the subject matter thereof

Matsco Subsidiary, which knowledge shall be deemed attributed to Matsco), and
each such statement shall constitute a representation that such investigation
has been conducted if so required.

their respective duties and obligations hereunder; provided that the corporate
affairs of Matsco are governed by the Delaware General Corporation Law.

         16.8 Captions. The captions contained in this Agreement are for
              --------

not affect the interpretation hereof.

         16.9 Severability. If any portion of this Agreement shall be deemed by
              ------------
a court of competent jurisdiction to be unenforceable, the remaining portions
shall be valid and enforceable only if, after excluding the portion deemed to be
unenforceable, the remaining terms hereof shall provide for the consummation of
the transactions contemplated herein in substantially the same manner as
originally set forth at the date this Agreement was executed.

         16.10 Waiver and Modification; Amendment. No waiver of any term,

attorneys' fees and other costs and expenses incurred in that action or
proceeding, in addition to any other relief to which it may be entitled.
