          (iii) Notwithstanding the provisions of Section 2.3(c)(ii), with
respect to the Aggregate Earn-Out Payments for the then current Earn-Out Period,
if the quotient obtained pursuant to the following formula is more than 0.53:

               A+B/ A+B+C+D+E, where

     A= the amount of cash to be included in the Aggregate Earn-Out Payments for
the then current Earn-Out Period

     B= the aggregate amount of cash included in the Initial Payment, the
Aggregate Earn-Out Payments for any and all prior Earn-Out Periods and the
payments for ABD Perfected Dissenting Shares pursuant to Section 2.6.

     C= the Aggregate Fair Market Value determined as of the Effective Time of
the 725,000 shares of GBB Preferred Stock included in the Initial Payment

     D= the Aggregate Fair Market Value determined as of the last day of each
prior Earn-Out Period of the number of shares of GBB Preferred Stock included in
the Aggregate Earn-Out Payments for any and all such prior Earn-Out Periods and

                                       14



     E= the Aggregate Fair Market Value determined as of the last day of the
current Earn-Out Period of the number of shares of GBB Preferred Stock to be
included in the Aggregate Earn-Out Payment for the current Earn-Out Period,

then the amount of cash to be included in the Aggregate Earn-Out Payments for
the current Earn-Out Period shall be reduced, and the number of shares of GBB
Preferred Stock shall be increased by one share for each $50.00 reduction in
cash, by the least amount required to result in the quotient obtained from the
above formula being 0.53 or less. All cash paid in lieu of fractional shares
pursuant to Section 2.5 shall be included in the making the calculations
pursuant to this Section 2.3(c)(iii) or Sections 2.3(c)(iv) and 2.3(c)(v).

          (iv) The Pro Rata Amount of the Aggregate Earn-Out Payments for each
Earn-Out Period, as reduced pursuant to and in accordance with the provisions of
Article VIII, shall be made 10 Business Days following the receipt by GBB of (A)
a certificate from GBB's independent public accountants setting forth the EBITDA

selected by GBB to determine the Fair Market Value of a share of GBB Preferred
Stock as of the last day of the Earn-Out Period, and (C) a certificate from
GBB's independent public accountants of the calculations required pursuant to
Sections 2.3(c)(ii) and (iii) above. The determinations made by GBB's
independent public accountants and investment banking firm with respect to the
foregoing shall be final and conclusive. GBB shall use its best efforts to cause
the accountants and investment banking firm to provide such certificates and
letter without undue delay. GBB shall use its commercially reasonable efforts to
make the payments for each Earn-Out Period within 60 days after the end of each
Earn-Out Period. Any payment delayed beyond such date shall bear interest at the
rate of 10% per annum on the Pro Rata Amount of the unpaid Aggregate Earn-Out
Payments for such Earn-Out Period, as reduced pursuant to and in accordance with
the provisions of Article VIII, calculated on the basis of a 365 day year from
the 60th day after the end of the applicable Earn-Out Period to the date of
payment. In addition, if any payment is made more than 120 days after the end of
the applicable Earn-Out Period, in addition to the interest accrued as provided
in the preceding sentence, such payment shall also include an amount equal to
10% of the Pro-Rata Amount of the unpaid Aggregate Earn-Out Payments for such
Earn-Out Period, as reduced pursuant to and in accordance with the provisions of
Article VIII.

          (v) Notwithstanding the provisions of Sections 2.3(c)(ii), (iii) and

determined by a nationally recognized investment banking firm selected by GBB
with respect to the Change in Control Payment and reasonably acceptable to the
ABD Shareholder's Representative.

Stock outstanding immediately prior to the Effective Time, and funds in an
amount not less than the amount of cash payable in lieu of fractional shares of

"Exchange Fund").

     (b) GBB shall direct the Exchange Agent to mail, promptly after the
Effective Time, to each holder of record of a certificate or certificates which
immediately prior to the Effective Time represented outstanding shares of ABD
Common Stock (the "Certificates") whose shares were

converted into the right to receive cash and shares of GBB Preferred Stock
pursuant to Section 2.3(c)(i) hereof, (i) a letter of transmittal (which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Exchange
Agent and shall be in such form and have such other provisions as GBB shall
specify), and (ii) instructions for use in effecting the surrender of the

Certificates for such cash and shares, because they have been lost or destroyed,

and certificate representing the proper number of shares of GBB Preferred Stock
into which the shares of ABD Common Stock have been converted pursuant to
Section 2.3(c)(i) hereof and cash in lieu of fractional shares in accordance

GBB Preferred Stock which are declared payable to shareholders of record of GBB

the certificates representing whole shares of GBB Preferred Stock issued in
exchange thereof, without interest, (i) at the time of such surrender, the
amount of any cash payable in lieu of a fractional share of GBB Preferred Stock

dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole shares of GBB Preferred Stock, and

distributions with a record date after the Effective Time but prior to surrender
and a payment date subsequent to surrender payable with respect to such whole
shares of GBB Preferred Stock.

and there shall be no further registration of transfers on the stock transfer
books of the Surviving Corporation of the shares of ABD Common Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective

Common Stock for such shares (or dividends or distributions with respect
thereto) or cash from the Exchange Fund delivered to a public official pursuant
to any applicable abandoned property, escheat or similar law.

of ownership with respect to the shares of GBB Preferred Stock held by it from
time to time hereunder, except that it shall receive and hold all dividends or
other distributions paid or distributed with respect to such shares of GBB
Preferred Stock for the account of the Persons entitled thereto.

3.17 Certain Material Changes. Except as Previously Disclosed, as reflected in
     ------------------------
the ABD Financial Statements, or as specifically required, permitted or effected
by this Agreement, since January 31, 2001, there has not been, occurred or
arisen any of the following (whether or not in the ordinary course of business
unless otherwise indicated):

     (a) any change in any of the assets, liabilities, permits, methods of
accounting or accounting practices, business, or manner of conducting business,

the assets, liabilities, permits, business, financial condition, results of
operations or prospects of ABD on a consolidated basis;

     (b) any damage, destruction or other casualty loss (whether or not covered
by insurance) that has had or may reasonably be expected to have a material
adverse effect on the assets, liabilities, business, financial condition,
results of operations or prospects of ABD on a consolidated basis or that may
involve a loss of more than $100,000 in excess of applicable insurance coverage;

     (c) any amendment, modification or termination of any existing, or entry

basis;

     (d) any disposition by ABD of an asset the lack of which has had or may

     (e) any direct or indirect redemption, purchase or other acquisition by ABD
of any equity securities or any declaration, setting aside or payment of any

consisting of money, other personal property, real property or other things of

3.18 Licenses and Permits. ABD has all material licenses and permits that are
     --------------------
necessary for the conduct of its business, and such licenses are in full force
and effect, except for the lack of any license or permit or any failure to be in
full force and effect that would not, individually or in the aggregate, have a
material adverse effect on the business, financial condition, results of
operations or prospects of ABD on a consolidated basis. The properties, assets,
operations and businesses of ABD are and have been maintained and conducted, in
all material respects, in compliance with all applicable licenses and permits.
The properties and operations of ABD are and have been

                                       32



maintained and conducted, in all material respects, in compliance with all
applicable laws and regulations.

reflected or disclosed in the ABD Financial Statements; (b) incurred subsequent
to January 31, 2001 in the ordinary course of business consistent with past
practices; or (c) Previously Disclosed. ABD does not know of any basis for the
assertion against it 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 change in the business, financial condition, results of
operations or prospects of ABD on a consolidated basis that is not fairly
reflected in the Financial Statements of ABD or otherwise disclosed in this
Agreement.

3.20 Employee Benefit Plans.
     ----------------------

     (a) ABD has previously made available to GBB copies of each "employee
benefit plan," as defined in Section 3(3) of ERISA, of which ABD or any member
of the same controlled group of corporations, trades or businesses as ABD within
the meaning of Section 4001(a)(14) of ERISA ("ERISA Affiliates") is a sponsor or
participating employer or as to which ABD or any of its ERISA Affiliates makes
contributions or is required to make contributions and which is subject to any
provision of ERISA and covers any employee, whether active or retired, of ABD or
any of its ERISA Affiliates, together with all amendments thereto, all currently
effective and related summary plan descriptions, the determination letter from
the IRS, the annual reports for the most recent three years (Form 5500
including, if applicable, Schedule B thereto) and a summary of material
modifications and all material employee communications prepared in connection
with any such plan. Such plans are hereinafter referred to collectively as the
"Employee Plans." ABD does not participate in an employee benefit pension plan
that is a "multiemployer plan" within the meaning of Section 3(37) of ERISA.
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 Plan is exempt from tax under Section 501(a) of the Code. To the
best of ABD's knowledge, no event has occurred that will subject any Employee
Plan to tax under Section 511 of the Code. All amendments required 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 Previously
Disclosed, all Employee Plans were in effect for substantially all of 2000 and
2001 to date, and there has been no material amendment thereof (other than
amendments required to comply with applicable law) or material increase in the
cost thereof or benefits thereunder on or after January 1, 2001.

     (b) ABD has previously furnished to GBB copies or descriptions of each plan
or arrangement maintained or otherwise contributed to by ABD or any of its ERISA
Affiliates 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, stock award, stock-based compensation or other forms of incentive
compensation or post-termination insurance, profit sharing, benefit, retirement,
group health or insurance, disability, workers' compensation, welfare or similar
plan or arrangement for the benefit of any employee or class of employees,
whether active or retired, of ABD or any of its ERISA Affiliates (such plans and
arrangements being collectively referred to herein as

                                       33



"Benefit Arrangements"). Except as Previously Disclosed, all Benefit
Arrangements which are in effect were in effect for substantially all of 2000
and 2001 to date. There has been no material amendment thereof or increase in
the cost thereof or benefits payable thereunder since January 1, 2001. Except as
Previously Disclosed, there has been no material increase in the compensation of
or benefits payable to any senior executive employee of ABD since October 31,
2001, nor any employment, severance or similar contract entered into with any
such employee, nor any amendment to any such contract, since October 31, 2001.

     (c) With respect to all Employee Plans and Benefit Arrangements, ABD and
its ERISA Affiliates are in material compliance (other than noncompliance the
cost or liability for which is not material) 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 in all material
respects and all information required to be distributed to participants or
beneficiaries has been distributed in all material respects with respect to each
Employee Plan. ABD and its ERISA Affiliates have performed all of their
obligations under all such Employee Plans and Benefit Arrangements in all
material aspects. There is no pending or, to the knowledge of ABD, threatened
legal action, proceeding or investigation against or involving any Employee Plan
or Benefit Arrangement. 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 or Section 4975 of the Code,
has occurred with respect to any Employee Plan, or any other employee benefit
plan maintained by ABD or to the best of ABD's knowledge any of its ERISA
Affiliates which is covered by Title I of ERISA, which could subject any person
(other than a person for whom ABD 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. No Employee Plan subject to Part III of Subtitle B of Title I
of ERISA or Section 412 of the Code, or both, has incurred any "accumulated
funding deficiency," as defined in Section 412 of the Code, whether or not
waived, nor has ABD 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 ERISA has occurred with respect to any of the
Employee Plans. Neither ABD nor to the best of ABD's knowledge any of its ERISA
Affiliates has incurred nor will 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 would constitute a liability of GBB or of any of its
Affiliates (including ABD) at or after the Effective Time of the Merger.

     (d) Neither ABD nor to the best of ABD's knowledge any of its ERISA
Affiliates has provided or is required to provide security to any Employee Plan
pursuant to Section 401(a)(29) of the Code. Each of the Employee Plans which is
intended to be a qualified plan under Section 401(a) of the Code has received a
favorable determination letter from the Internal Revenue Service and ABD does
not know of any fact which would adversely affect the qualified status of any
such Employee Plan. All contributions required to be made to each of the
Employee Plans under the terms of the Employee Plan, ERISA, the Code or any
other applicable laws have been timely made.

                                       34



The Financial Statements of ABD properly reflect all amounts required to be
accrued as liabilities to date under each of the Employee Plans. The fair market
value of the assets of each Employee Plan and Benefit Arrangement that is
funded, or required to be funded under the terms of the Employee Plan or Benefit
Arrangement, ERISA, the Code or any other applicable law, equals or exceeds the
liabilities, including the present value of benefit obligations, of such
Employee Plan or Benefit Arrangement.

     (e) Except for the Scheduled Contracts or as Previously Disclosed, 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 ABD within a period of 30 days following the Effective Time of
the Merger, without payment of any amount as a penalty, bonus, premium,
severance pay or other compensation for such termination.

     (f) All group health plans of ABD have been operated in compliance with the
group health plan continuation coverage requirements of Section 4980B of the
Code and with the group health plan portability, access and renewability
requirements of Sections 9801 through 9833 of the Code, and corresponding
provisions of ERISA, in all material respects.

     (g) Except as Previously Disclosed, ABD has not used the services of (i)
workers who have been provided by a third party contract labor supplier for more
than six months or who may otherwise be eligible to participate in any of the
Employee Plans or to an extent that would reasonably be expected to result in
the disqualification of any of the Employee Plans or the imposition of penalties
or excise taxes with respect to the IRS, the Department of Labor, the Pension
Benefit Guaranty Corporation or any other Governmental Entity; (ii) temporary
employees who have worked for more than six months or who may otherwise be
eligible to participate in any of the Employee Plans or to an extent that would
reasonably be expected to result in the disqualification of any of the Employee
Plans or the imposition of penalties or excise taxes with respect to the IRS,
the Department of Labor, the Pension Benefit Guaranty Corporation or any other
Governmental Entity; (iii) individuals who have provided services to ABD as
independent contractors for more than six months or who may otherwise be
eligible to participate in the Employee Plans or to an extent that would
reasonably be expected to result in the disqualification of any of the Employee
Plans or the imposition of penalties or excise taxes with respect to the IRS,
the Department of Labor, the Pension Benefit Guaranty Corporation or any other
Governmental Entity or (iv) leased employees, as that term is defined in section
414(n) of the Code.

     (h) Except as Previously Disclosed, with respect to each Employee Plan that
is funded wholly or partially through an insurance policy, there will be no
liability of ABD, as of the Closing Date, under any such insurance policy or
ancillary agreement with respect to such insurance policy in the nature of a
retroactive rate adjustment, loss sharing arrangement or other actual or
contingent liability arising wholly or partially out of events occurring prior
to the Closing Date.

3.21 Corporate Records. The minute books of each of ABD accurately reflect all
     -----------------

accepted accounting principles. Such records, to the extent they contain
important information pertaining to ABD which is not easily and readily

     -----------------
similar authorization that is presently in effect or outstanding.

3.25 Facts Affecting Regulatory Approvals. To the best knowledge of ABD, there

be expected to, adversely affect the likelihood of securing the requisite
approvals or consents of any Governmental Entity to the Merger and the
transactions contemplated by this Agreement.

3.26 Tax Matters. ABD has not through the date hereof taken or agreed to take
     -----------
any action that would prevent the Merger and the Second Merger from qualifying

assets of ABD and as a tax-free reorganization under the Code.

3.27 Indemnification. Other than pursuant to the provisions of its Articles of
     ---------------
Incorporation or Bylaws, and the Consultant's Agreement, ABD is not a party to
any indemnification agreement with any of its present officers, directors,
employees, agents or other persons who serve or served in any other capacity
with any other enterprise at the request of ABD (a "Covered Person"), and to the
best knowledge of ABD, there are no claims for which any Covered Person would be
entitled to indemnification by ABD if such provisions were deemed in effect.

3.28 Disclosure Documents and Applications. None of the information supplied or
     -------------------------------------
to be supplied by or on behalf of ABD ("ABD Supplied Information") for inclusion
in (a) the proxy statement to be sent to the shareholders of ABD; (b) the
fairness hearing documents to be filed with the Commissioner of Corporations;
and (c) any other documents to be filed with the FRB, the Commissioner of

     -----------------------
otherwise, to register any of its securities under the Securities Act.

affecting ABD, including without limitation any transactions, arrangements or

against or disputes with ABD which could result in the imposition of any
liability or judgment against ABD.

GBB Filings. As of their respective dates, each of such GBB Filings (y) complied

8.2 Indemnification by the ABD Shareholders; Right to Offset.
    --------------------------------------------------------

     (a) Anything in this Agreement to the contrary notwithstanding, subject to
the provisions of this Article VIII, the ABD Shareholders hereby agree to
jointly and severally indemnify, defend and hold GBB, the Surviving Corporation,
and the Second Surviving Corporation and their respective officers and
directors, and each Person, if any, who controls or may control GBB within the
meaning of the Securities Act (all such Persons hereinafter are referred to
individually as a "GBB Indemnified Person" and collectively as "GBB Indemnified
Persons," but in no event shall any ABD Shareholder prior to the Effective Time
be such a GBB Indemnified Person) harmless against all Losses resulting from,
imposed upon or incurred by any GBB Indemnified Person, directly or indirectly,
as a result of any of the following:

          (i) any inaccuracy or breach of a representation or warranty of ABD
given or made by ABD in this Agreement or in any certificate, document or
agreement delivered by or on behalf of ABD pursuant hereto;

                                       57



          (ii) any failure by ABD to perform or comply with any covenant or
agreement contained in this Agreement or in any certificate, document or
agreement delivered by or on behalf of ABD pursuant hereto; and

          (iii) The conduct and operation of the business of ABD prior to the
Effective Time, except to the extent any such Loss had been accrued as a
liability on the balance sheet used to calculate the Tangible Net Worth of ABD
as of December 31, 2001.

     (b) In the event, from time to time, any GBB Indemnified Person or the ABD
Shareholders' Representative determines that any GBB Indemnified Person has
suffered a Loss for which indemnification is available pursuant to this Article
VIII, the following procedure shall be followed:

          (i) GBB Indemnified Person shall give written notice of any such claim
(a "Loss Notice") to the ABD Shareholders' Representative specifying in
reasonable detail the amount of the claimed Loss (the "Loss Amount") and the
basis for such Loss and that GBB intends to offset against the Aggregate
Earn-Out Payments for any Earn-Out Period (including the modification of the
Aggregate Earn-Out Payments pursuant to Section 2(c)(v) relating to the Change
in Control Payment and pursuant to Section 2(c)(vi) relating to the ABD Sale
Payment) and Pro-Rata Amounts with respect thereto payable pursuant to Section
2(c) of this Agreement.

          (ii) Within ten (10) days after delivery of a Loss Notice, the ABD
Shareholders' Representative shall provide to GBB and the GBB Indemnified Person
(if not the same Person), a written response (a "Response Notice") in which the
ABD Shareholders' Representative will (i) agree that an offset in the full Loss
Amount may be made against such Aggregate Earn-Out Payments, (ii) agree that an
offset in an amount equal to part, but not all, of the Loss Amount (the "Agreed
Amount") may be made against such Aggregate Earn-Out Payments or (iii) contest
making any offset against such Aggregate Earn-Out Payments. The ABD
Shareholders' Representative may contest an offset against such Aggregate
Earn-Out Payments upon a good faith belief that all or such portion of such
offset does not constitute a Loss for which the GBB Indemnified Person is
entitled to indemnification under this Article VIII. If no Response Notice is
delivered by the Shareholders' Representative within such ten (10) day period,
the ABD Shareholders shall be deemed to have agreed that an offset in the full
Loss Amount may be made against such Aggregate Earn-Out Payments.

          (iii) If the ABD Shareholders' Representative in the Response Notice
agrees (or is deemed to have agreed), that an offset may be made against such
Aggregate Earn-Out Payments in an amount equal to the Loss Amount, such
Aggregate Earn-Out Payments shall be reduced in the following manner. With
respect to each Earn-Out Period (or the Change in Control Payment or ABD Sale
Payment), the cash to be included in the Aggregate Earn-Out Payments for such
Earn-Out Period as determined pursuant to Section 2.3(c)(ii) and (iii) (or the
Change in Control Payment or ABD Sale Payment) shall be reduced by an amount
equal to 60% of the Loss Amount and the stock to be included in the Aggregate
Earn-Out Payment for such Earn-Out Period as determined pursuant to Section
2.3(c)(ii) and (iii) (or the Change in Control Payment or ABD Sale Payment)
shall be

                                       58



reduced by a number of shares (rounded to the nearest whole share) of GBB
Preferred Stock or GBB common stock, whichever is applicable, equal to 40% of
the Loss Amount divided by the fair market value of such security. The fair
market value of the GBB Preferred Stock shall be determined as provided in
Section 2.3(c)(iv) and the fair market value of the GBB common stock shall be
determined as provided in Section 2.3(c)(v)(3). The Pro-Rata Amount of the
Aggregate Earn-Out Payments for such Earn-Out Period (or the Change in Control
Payment or ABD Sale Payment) otherwise payable to each ABD Shareholder shall be
proportionately reduced to reflect the amount of cash and securities deducted
pursuant to this Section 8.2(b)(iii). If the Loss Amount exceeds the Aggregate
Earn-Out Payments for any Earn-Out Period, such excess Loss Amount shall be
carried over to the next Earn-Out Period (or the Change in Control Payment or
ABD Sale Payment if such payment is required to be made prior to the end of the
next Earn-Out Period) and the Aggregate Earn-Out Payments for such subsequent
Earn-Out Period (or the Change in Control Payment or ABD Sale Payment if such
payment is required to be made prior to the end of the next Earn-Out Period)
shall be reduced in the same manner as provided in this Section 8.1(b)(iii).

          (iv) If the ABD Shareholders' Representative in the Response Notice
agrees that an offset in an Agreed Amount may be made against such Aggregate
Earn-Out Payments, the Aggregate Earn-Out Payments for each Earn-Out Period (or
the Change in Control Payment or ABD Sale Payment if such payment is required to
be made prior to the end of the next Earn-Out Period) shall be reduced in an
amount equal to the Agreed Amount in the same manner as provided in Section
8.1(b)(iii).

          (v) If the ABD Shareholders' Representative in the Response Notice
contests an offset against such Aggregate Earn-Out Payments equal to all or any
part of the Loss Amount (the "Contested Amount"), the GBB Indemnified Person and
the ABD Shareholders' Representative shall negotiate in good faith to resolve
any such dispute. If any such dispute involving claims of less than $1,000,000
cannot be resolved within fifteen (15) days after the receipt by GBB of the
Response Notice, the GBB Indemnified Person and the ABD Shareholders'
Representative shall submit the matter to the San Francisco office of the
American Arbitration Association ("AAA") for binding arbitration to be conducted
in accordance with the AAA commercial arbitration rules in effect at the time
such matter is submitted. If any such matter is submitted to the AAA as provided
herein, (A) each of the GBB Indemnified Person and the ABD Shareholders'
Representative will furnish to AAA such workpapers and other documents and
information as AAA may request and will be afforded the opportunity to present
to AAA any material relevant to the matter, (B) the determination by AAA, as set
forth in a notice delivered to the GBB Indemnified Person and the ABD
Shareholders' Representative by AAA, will be binding and conclusive on such
parties. The Aggregate Earn-Out Payments for each Earn-Out Period (or the Change
in Control Payment or ABD Sale Payment if such payment is required to be made
prior to the end of any Earn-Out Period) shall be reduced by an amount equal to
the dollar amount of the award set forth in such determination (as evidenced by
such notice from AAA) in the same manner as provided in Section 8(b)(iii).

          (vi) In connection with any such commercial arbitration, the following
rules also shall apply: (A) any party shall have the right to have counsel
represent such party at the arbitration hearing and in pre-arbitration
proceedings; (B) all parties shall be permitted to conduct discovery in

                                       59



accordance with the Federal Rules of Civil Procedure; (C) the arbitrator(s)
shall have the authority to resolve any discovery disputes and to invoke an
action to cease further discovery; (D) each party to any arbitration proceeding
shall have the right to a written transcript made of the arbitration
proceedings; (E) each party shall have the right to file post-arbitration
briefs, which shall be considered by the arbitrator(s); and (F) each party shall
bear its own costs and expenses and attorney's fees in connection with such
arbitration except that the Surviving Corporation shall advance any costs of the
ABD Shareholders.

          (vii) In the event of any disputes involving claims of $1,000,000 or
more, any party shall have the right to bring such action in any state or
federal court of competent jurisdiction in the State of California. The
Aggregate Earn-Out Payments for each Earn-Out Period (or the Change in Control
Payment or ABD Sale Payment if such payment is required to be made prior to the
end of any Earn-Out Period) shall be reduced by an amount equal to the dollar
amount of the non-appealable judgment of such a court of competent jurisdiction
in the same manner as provided in Section 8(b)(iii).

          (viii) If at the end of the last Earn-Out Period (or at the time of
the Change in Control Payment or ABD Sale Payment if such payment is required to
be made prior to the end of any Earn-Out Period), there is any Contested Amount
still unresolved, GBB shall withhold from the Aggregate Earn-Out Payments for
such Earn-Out Period (or the Change in Control Payment or ABD Sale Payment if
such payment is required to be made prior to the end of any Earn-Out Period) an
amount equal to the lesser of the Contested Amount or the amount of such
Aggregate Earn-Out Payment (or Change in Control Payment or ABD Sale Payment, if
applicable) (the "Holdback Amount"). The Holdback Amount shall be comprised to
the extent possible of cash to be included in such Aggregate Earn-Out Payments
(or Change in Control Payment or ABD Sale Payment if applicable) in an amount
equal to sixty percent (60%) of the Holdback Amount and of a number of shares of
GBB Preferred Stock or GBB common stock, whichever is applicable, equal to 40%
of the Holdback Amount divided by the fair market value of such security. If the
Holdback Amount cannot be allocated in these proportions between cash and stock,
it shall then be allocated as closely as possible to these percentages. The fair
market value of such security shall be determined as provided in Section
8.2(b)(iii). The Pro Rata Amount of the Aggregate Earn-Out Payments for such
Earn-Out Period (or the Change in Control Payment or ABD Sale Payment) otherwise
payable to each ABD Shareholder shall be proportionally reduced to reflect the
amount of the cash and securities required to be withheld pursuant to this
Section 8.2(b)(viii), and such Holdback Amount shall be distributed to the ABD
Shareholders or GBB, as the case may be, only in accordance with the terms of
this Agreement. The Holdback Amount will be retained by GBB as security for the
performance of the indemnity obligations of the ABD Shareholders under Section
8.2 of this Agreement, subject to reduction for any unresolved indemnification
claims of GBB pursuant to Section 8.2. Each ABD Shareholder who votes in favor
of the Merger pursuant to the terms hereof by such vote, without any further
action, and each ABD Shareholder who receives cash and GBB Preferred Stock in
connection with Merger, by acceptance thereof and without any further action,
hereby confirms and agrees to the grant to GBB of the security interest in the
Holdback Amount and grants to GBB a continuing limited power of attorney,
coupled with an interest to deal with the Holdback Amount as provided in this
Section 8.2(b)(viii), and such power of attorney is not revocable until the
final determination and

                                       60



settlement of any Contested Amounts pursuant to Section 8.2 of this Agreement.
To the extent it is determined that GBB is entitled to be indemnified with
respect to any portion of the Contested Amount pursuant to Section 8.2, GBB
shall have the right to deduct from the Holdback Amount such portion of the
Contested Amount allocable between the cash and securities included in the
Holdback Amount as GBB determines in its sole discretion. If after all Contested
Amounts are resolved as provided in Section 8.2 and any portion of the Holdback
Amount remains, GBB shall thereafter distribute such remaining Holdback Amount
plus an amount equal to the interest that would be deemed earned on such
remaining Holdback Amount distributed to the ABD Shareholders calculated at the
rate of 5% per annum on such remaining Holdback Amount on the basis of 365 day
year from the date the Holdback Amount is withheld to the date of repayment of
any such remaining Holdback Amount is withheld to the date of repayment of any
such remaining Holdback Amount to the ABD Shareholders pursuant to this Section
8.2(b)(vii) to the ABD Shareholders prorata in accordance with the number of
shares of issued and outstanding ABD Common Stock held by such ABD Shareholder
immediately prior to the Effective Time as reflected in the report provided by
ABD to GBB and the Exchange Agent at Closing.

     (c) The indemnity obligations of the ABD Shareholders under this Article
VIII shall be only satisfied through the exercise by GBB of the right of offset
against the Aggregate Earn-Out Payments (or the Change in Control Payment or ABD
Sale Payment) otherwise issuable pursuant to Section 2.3(c).

     (d) The exercise of such right of offset by GBB in good faith, whether or
not ultimately determined to be justified, will not constitute a breach of this
Agreement. Neither the exercise of nor the failure to exercise such right of
offset will constitute an election of remedies or limit GBB in any manner in the
enforcement of any other remedies available to GBB.

     (e) Notwithstanding the foregoing provisions of this Section 8.2 to the
contrary, the following limitations with respect to the indemnification
obligations of the ABD Shareholders under Article VIII shall apply:

          (i) The ABD Shareholders shall not be liable for any amounts under
this Section 8.2 unless and until the aggregate of Losses suffered by the GBB
Indemnified Party(ies) from all claims for indemnification exceed $75,000, in
which case the ABD Shareholders shall be liable for the full amount of Losses
suffered by the GBB Indemnified Party(ies), including the first $75,000; and

          (ii) In no event shall the ABD Shareholders be liable to the GBB
Indemnified Party(ies) for amounts under this Article VIII aggregating in excess
of $50,000,000; provided, however, that the limitations set forth in this clause
(ii) shall not apply with respect to any Loss which is the result of fraud or
intentional misrepresentation on the part of ABD or the ABD Shareholders.

                                       61



8.3 Third Party Claims. The obligations and liabilities of the ABD Shareholders
    ------------------
with respect to their respective indemnities pursuant to this Article VIII,
resulting from any third party claim ("Third Party Claim") shall be subject to
the following terms and conditions:

     (a) The party seeking indemnification (the "Indemnified Party") must give
the party obligated to indemnify (the "Indemnifying Party"), notice of any Third
Party Claim which is asserted against, resulting to, imposed upon or incurred by
the Indemnified Party and which may give rise to liability of the Indemnifying
Party pursuant to this Article VIII, stating (to the extent known or reasonably
anticipated) the nature and basis of such Third Party Claim and the amount
thereof; provided that the failure to give such notice shall not affect the
rights of the Indemnified Party hereunder except to the extent (i) that the
Indemnifying Party shall have suffered actual damage by reason of such failure,
or (ii) such failure or delay materially adversely affects the ability of the
Indemnifying Party to defend, settle or compromise such Third Party Claim.

     (b) Subject to Section 8.3(c) below, if the Indemnifying Party assumes
responsibility for Losses arising out of such Third Party Claim, then the
Indemnifying Party shall have the right to undertake, by counsel or other
representatives of its own choosing, the defense of such Third Party Claim at
the Indemnifying Party's risk and expense.

     (c) In the event that (i) the Indemnifying Party shall elect not to
undertake such defense, (ii) within a reasonable time after notice from the
Indemnified Party of any such Third Party Claim, the Indemnifying Party shall
fail to undertake to defend such Third Party Claim, or (iii) there is a
reasonable probability that such Third Party Claim may materially and adversely
affect the Indemnified Party other than as a result of money damages or other
money payments, then the Indemnified Party (upon further written notice to the
Indemnifying Party) shall have the right to undertake the defense, compromise or
settlement of such Third Party Claim, by counsel or other representatives of its
own choosing, on behalf of and for the account and risk of the Indemnifying
Party. In the event that the Indemnified Party undertakes the defense of a Third
Party Claim under this Section 8.3, the Indemnifying Party shall pay to the
Indemnified Party, in addition to the other sums required to be paid hereunder,
the reasonable costs and expenses incurred by the Indemnified Party in
connection with such defense, compromise or settlement as and when such costs
and expenses are so incurred.

     (d) Anything in this Section 8.3 to the contrary notwithstanding, neither
the Indemnified Party nor the Indemnifying Party shall, without the other
party's written consent (which consent shall not be unreasonably withheld or
delayed), settle or compromise such Third Party Claim or consent to entry of any
judgment which does not include as an unconditional term thereof the giving by
the claimant or the plaintiff to the Indemnified Party of a release from all
liability in respect of such Third Party Claim in form and substance
satisfactory to the Indemnified Party. In all cases where such release is
granted, if a firm written offer is made to settle any Third Party Claim, and
the Indemnifying Party proposes to accept such settlement and the Indemnified
Party refuses to consent to such settlement then (A) the Indemnifying Party
shall be excused from and the Indemnified Party shall be solely responsible for
all further defense of such Third Party Claim; (B) the maximum liability of the
Indemnifying Party relating to such Third Party Claim shall be the amount of the

                                       62



proposed settlement if the amount thereafter recovered from the Indemnified
Party on such Third Party Claim is greater than the amount of the proposed
settlement; and (C) the Indemnified Party shall pay all attorney's fees and
legal costs and expenses incurred after rejection of such settlement by the
Indemnified Party, but if the amount thereafter recovered by such Third Party
from the Indemnified Party is less than the amount of the proposed settlement,
the Indemnified Party shall be reimbursed by the Indemnifying Party for such
attorney's fees and legal costs and expenses up to the maximum amount equal to
the difference between the amount recovered by such Third Party and the amount
of the proposed settlement.

8.4 No Recourse against ABD, GBB, the Surviving Corporation or the Second
    ---------------------------------------------------------------------
Surviving Corporation. Each ABD Shareholder hereby irrevocably waives any and
- ---------------------
all right to recourse against ABD, GBB, the Surviving Corporation or the Second
Surviving Corporation with respect to any misrepresentation or breach of any
representation, warranty or indemnity, or noncompliance with any conditions or
covenants, given or made by ABD in this Agreement or any other agreements and

pursuant to this Agreement or any of the other agreements and documents executed
or to be executed by the parties hereto in order to consummate the transactions
contemplated by this Agreement or such other agreements and documents
contemplated hereby, whether in such person's capacity as a shareholder,
director, officer, employee or agent of ABD. Notwithstanding the foregoing, the
Surviving Corporation or the Second Surviving Corporation, as the case may be,
shall advance costs of defense of any Third Party Claim and the ABD Shareholders
shall not be required to advance any funds for the defense of any such Third
Party Claim. Each ABD Shareholder who votes in favor of the Merger pursuant to
the terms hereof, by such vote, without any further action, and each ABD
Shareholder who receives cash and shares of GBB Preferred Stock in connection
with the Merger, by acceptance thereof and without any further action, agrees to
the provisions of this Article VIII.

substitution in the premises), in connection with the indemnity provisions of
Article VIII as they relate to ABD and the ABD Shareholders generally, and such
other matters as are reasonably necessary for the consummation of the
transactions contemplated hereby including, without limitation, (i) to review
all claims for indemnification asserted by a GBB Indemnified Person, and, to the
extent deemed appropriate, dispute, question the accuracy of, compromise, settle
or otherwise resolve any and all such claims, (ii) to compromise on their behalf
with GBB any claims asserted thereunder, (iii) to authorize payments to be made
with respect to any such claims for indemnification, (iv) to execute and deliver

administering post-closing matters related to the rights and obligations of the
ABD Shareholders as are authorized in this Agreement (the above named
representative, as well as any subsequent representative of the ABD Shareholders
appointed by the ABD Shareholders being referred to herein as the "ABD
Shareholders' Representative"). The ABD Shareholders' Representative shall not
be liable to any ABD Shareholder, GBB, the Surviving Corporation, the Second
Surviving Corporation or their respective affiliates or any other Person with
respect to any action taken or omitted to be taken by the ABD Shareholders'
Representative in his role as ABD Shareholders' Representative under or in
connection with this Agreement unless such action or omission results from or
arises out of fraud, gross negligence or willful misconduct on the part of the
ABD Shareholders' Representative. GBB, the Surviving Corporation and the Second
Surviving Corporation shall be entitled to rely on such appointment and treat

each ABD Shareholder. Each ABD Shareholder who votes in favor of the Merger
pursuant to the terms hereof, by such vote, without any further action, and each
shareholder of ABD who receives cash and GBB Preferred Stock in connection with
the Merger, by acceptance thereof and without any further action, confirms such
appointment and authority. Should the named ABD Shareholders' Representative

Common Stock outstanding immediately prior to the Effective Time shall be
entitled to elect a successor ABD Shareholders' Representative.

     The Hurdle EBITDA, Forecast EBITDA and Hurdle Amount for each Earn-Out
Period are subject to adjustment if ABD, the Surviving Corporation or the Second
Surviving Corporation acquires any other insurance agencies during such Earn-Out
Period as follows:

     For each agency acquired during the Earn-Out Period with pro forma EBITDA
     -------------------------------------------------------------------------
of $5.0 million per annum or less, the "Basic Formula" outlined below will apply
- --------------------------------------------------------------------------------
subject to the limit included in the "Basic Formula". If the acquired agency has
- ---------------------------------------------------
pro forma EBITDA in excess of $5.0 million the management of GBB and the ABD
Shareholders' Representative will mutually agree on a formula specific to such
an acquisition, or will agree on a cost of capital ("COC") appropriate for the
acquisition to reflect the return on investment expectation of GBB shareholders
and the risks of the project and the Hurdle EBITDA, Forecast EBITDA and Hurdle
Amount for each Earn-Out Period will be adjusted accordingly.

The Basic Formula:
- -----------------

 .    For each acquisition identified, the post acquisition EBITDA actually
     generated by the acquisition will be included in EBITDA for the applicable
     Earn-Out Period.

 .    Each acquisition will have a COC charge of 15% calculated based on the
     purchase price. This level is reflective of GBB's current minimum level of
     internal rate of return on such acquisitions.

 .    For the purpose of the Base Earn-Out Payment for each Earn-Out Period, the
     COC charge will not be added to Hurdle EBITDA for each Earn-Out Period.

 .    For purposes of the Incremental Earn-Out Payment and Excess Earn-Out
     Payment for each Earn-Out Period the Hurdle EBITDA and Forecast EBITDA for
     each Earn-Out Period will be increased by the amount of the COC charge.

 .    The "Basic Formula" will apply only as long as the cumulative pro forma
     EBITDA of all acquisitions effected under the Basic Formula does not exceed
     in any of the four Earn-Out Periods, 25% of the Forecast EBITDA for such
     Earn-Out Period. Once that threshold is reached, GBB and the ABD
     Shareholders' Representative will agree to a mutually acceptable amendment
     to the Basic Formula or a new formula specific to the situation as
     applicable and the Hurdle EBITDA, Forecast EBITDA and Hurdle Amount for
     each such Earn-Out Period



     shall be modified accordingly.

     The Basic Formula described above assumes the following five key elements:

 .    Future acquisitions must be accretive to the combined entity and generate
     return on equity in the 20%-25% range consistent with GBB's historical
     return on equity performance

 .    No single acquisition may exceed $5.0 million of annual pro-forma acquired
     EBITDA

 .    A maximum acquisition EBITDA multiple of 6.0x is applied; the need to apply
     an acquisition multiple in excess of 6.0x will require a mutual
     reassessment by GBB and the ABD Shareholders' Representative of the Basic
     Formula

 .    A GBB COC of 15%

 .    The Basic Formula only applies until December 31, 2005.
