10:00 a.m. on a date to be specified by the parties, which shall be no later
than the third Business Day after satisfaction or waiver of all of the
conditions set forth in Article VII hereof (the "Closing Date"), at the offices
of Jackson Walker L.L.P., 112 East Pecan Street, Suite 2100, San Antonio, Texas
78205, unless another date, time or place is agreed to in writing by the parties
hereto.
 
     2.5  Effects of the Merger. The Merger shall have the effects set forth in
Section 1107 of the GCL. Without limiting the generality of the foregoing, and
subject thereto, at the Effective Time all the property, rights, privileges,
powers and franchises of the Company and Purchaser shall vest in the Surviving
Corporation, and all debts, liabilities and duties of the Company and Purchaser
shall become the debts, liabilities and duties of the Surviving Corporation.
 
     2.6  Articles of Incorporation. The Articles of Incorporation of the
Company as in effect immediately prior to the Effective Time shall be amended as
of the Effective Time so that Article III thereof shall read in its entirety as
follows:
 
                                      "III
 
        This corporation is authorized to issue 1,000 shares of Common
        Stock, no par value per share."
 
As so amended, such Articles of Incorporation shall be the Articles of
Incorporation of the Surviving Corporation, until thereafter changed or amended,

     2.7  Bylaws. The Bylaws of Company, as in effect immediately prior to the

applicable law, the Articles of Incorporation of the Surviving Corporation or
such Bylaws.

of Incorporation
 
                                        4

and Bylaws of the Surviving Corporation, as such instruments may be amended from
time to time, either before or after the Effective Time, or as otherwise
provided by law.
 
     2.9  Officers. The officers of the Purchaser immediately prior to the

will hold office from the Effective Time until their respective successors are
duly elected or appointed and qualified in the manner provided in the Articles
of Incorporation and Bylaws of the Surviving Corporation, as such instruments
may be amended from time to time, either before or after the Effective Time, or
as otherwise provided by law.
 
     2.10  Conversion of Shares. At the Effective Time, by virtue of the Merger
and without any action on the part of Parent, Purchaser, the Company or the
holders of the Shares:
 
          (a) Each Share issued and outstanding immediately prior to the
     Effective Time (other than Shares held, directly or indirectly, by Parent,
     Purchaser, Gambrinus, the Company or any of their majority-owned
     Subsidiaries, and any Dissenting Shares (as defined in Section 2.11)) shall
     automatically be canceled and extinguished and be converted into the right
     to receive from the surviving corporation in cash the Merger Consideration,
     without interest thereon. Each holder (other than holders referred to in
     Section 2.10(b)) of a certificate representing any Shares shall after the
     Effective Time cease to have any rights with respect to such Shares, except
     either to receive the Merger Consideration upon surrender of such
     certificate, or to exercise such holder's dissenter's rights as provided in
     Section 2.11 and the GCL.
 
          (b) Each Share issued and outstanding immediately prior to the
     Effective Time which is owned or held, directly or indirectly, by Parent,
     Purchaser, Gambrinus, the Company or any of their majority-owned
     Subsidiaries shall be canceled and extinguished and cease to exist, without
     any conversion thereof, and no payment shall be made with respect thereto.
 
          (c) Each share of Common Stock of Purchaser issued and outstanding
     immediately prior to the Effective Time shall be converted into and
     thereafter represent one validly issued, fully paid and nonassessable share
     of Common Stock, no par value, of the Surviving Corporation.
 
     2.11  Dissenting Shares. Notwithstanding anything in this Agreement to the
contrary, Shares which are outstanding immediately prior to the Effective Time
and which are held by a holder who has not voted in favor of the Merger or
consented thereto in writing and who has demanded appraisal for such Shares in
accordance with Section 1300 of the GCL, if Section 1300 provides for appraisal
rights for such Shares in the Merger ("Dissenting Shares"), shall not be
converted into the right to receive the Merger Consideration pursuant to Section
2.10, unless and until such holder fails to perfect or withdraws or otherwise
loses the right to appraisal and payment under the GCL. If, after the Effective
Time, any such holder shall have failed to perfect or shall withdraw or lose
such holder's right of appraisal and payment under the GCL, such holder's Shares
shall be treated as if they had been converted as of the Effective Time into the
right to receive the Merger Consideration, without interest thereon, as provided
in Section 2.10, and such Shares shall no longer be Dissenting Shares. The
Company shall give Parent and Purchaser prompt notice of any demands received by
the Company for appraisal of Shares, and of any withdrawals of demands for
appraisal, or of any other instruments served pursuant to Section 1300 of the
GCL and received by the Company. Prior to the Effective Time, Parent and
Purchaser shall have the right to participate in all negotiations and
proceedings with respect to such demands for appraisal. Prior to the Effective
Time, the Company shall not, except with the prior written consent of Parent and
Purchaser, make any payment with respect to, or settle or offer to settle, any
such demands. Each holder of Dissenting Shares shall have only such rights and
remedies as are granted to such holder under Section 1300 of the GCL.
 
     2.12  Payment For Shares.
 
     (a) Prior to the Effective Time, Purchaser shall select and appoint a bank
or trust company reasonably acceptable to the Company to act as agent for the
holders of Shares (the "Paying Agent") to receive and disburse the Merger
Consideration to which holders of Shares shall become entitled pursuant to
Section 2.10. At the Effective Time, Purchaser or Parent shall, and Gambrinus
shall cause Purchaser or Parent to, deposit in trust with the Paying Agent for
the benefit of holders of Shares the aggregate consideration to which such
holders shall be entitled at the Effective Time pursuant to Section 2.10. Such
funds shall be invested as
 
                                        5
   9
 
directed by Parent or the Surviving Corporation pending payment thereof by the
Paying Agent to holders of the Shares. Earnings from such investments shall be
the sole and exclusive property of Purchaser and the Surviving Corporation and
no part thereof shall accrue to the benefit of the holders of the Shares. If for
any reason (including losses) such funds are inadequate to pay the amounts to
which holders of Shares shall be entitled under Section 2.10, Parent shall in
any event be liable for payment thereof. Such funds deposited with the Paying
Agent pursuant to this Section 2.12 shall not be used for any purpose except as
expressly provided in this Agreement. From time to time at or after the
Effective Time, Parent shall take all lawful action necessary to make the
appropriate cash payments, if any, to holders of Dissenting Shares.
 
     (b) As soon as practicable after the Effective Time, Purchaser or Parent
shall cause the Paying Agent to mail to each record holder a certificate or
certificates representing Shares which as of the Effective Time represents the
right to receive the Merger Consideration (the "Certificates"), a form of letter
of transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon proper delivery of the
Certificates to the Paying Agent) and instructions for use in effecting the
surrender of the Certificates for payment therefor. Upon surrender to the Paying
Agent of a Certificate, together with such letter of transmittal duly executed
and completed in accordance with the instructions thereto, and such other
documents as may be reasonably required by the Paying Agent, the holder of such
Certificate shall be entitled to receive in exchange therefor the Merger
Consideration and such Certificate shall forthwith be canceled. No interest
shall be paid or accrued on the Merger Consideration upon the surrender of the
Certificates. Until surrendered in accordance with the provisions of this
Section 2.12(b), each Certificate shall be deemed for all purposes to evidence
only the right to receive the Merger Consideration (without interest thereon),
and shall, subject to Section 2.11, have no other right.
 
     (c) If the Merger Consideration (or any portion thereof) is to be delivered
to a person other than the person in whose name the Certificates surrendered in
exchange therefor are registered, it shall be a condition to the payment that
the Certificates so surrendered shall be properly endorsed or otherwise be in
proper form for transfer and that the person requesting such payment or delivery
shall pay any transfer or other taxes payable by reason of the payment of the
Merger Consideration to a person other than the person in whose name the
Certificates are registered or establish to the satisfaction of the Surviving
Corporation that such tax has been paid or is not applicable. Notwithstanding
the foregoing, neither the Paying Agent nor any party hereto shall be liable to
a holder of Shares for any Merger Consideration delivered to a public official
pursuant to any applicable abandoned property, escheat and similar laws.
 
     (d) Promptly following the date that is one year after the Effective Time,
the Paying Agent shall return to the Surviving Corporation all Merger
Consideration and other cash, property and instruments in its possession
relating to the transactions described in this Agreement, and the Paying Agent's
duties shall terminate. Thereafter, such holders shall be entitled to look to
the Surviving Corporation (subject to abandoned property, escheat or similar
laws) only as general creditors thereof with respect to the Merger Consideration
payable upon due surrender of their Certificates, without any interest thereon.
Notwithstanding the foregoing, neither the Surviving Corporation nor the Paying
Agent shall be liable to any holder of a Certificate for Merger Consideration
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law.
 
     2.13  No Further Rights or Transfers. All cash paid upon surrender of
Certificates in accordance with the terms of this Article II shall be deemed to
have been paid in full satisfaction of all rights pertaining to the Shares
theretofore represented by such Certificate. At and after the Effective Time the
holders of Certificates to be exchanged for the Merger Consideration pursuant to
this Agreement shall cease to have any rights as shareholders of the Company
except for the right to surrender such holder's Certificates in exchange for
payment of the Merger Consideration, and after the Effective Time there shall be
no transfers on the stock transfer books of the Surviving Corporation of the
Shares which were outstanding immediately prior to the Effective Time. Any
Certificates formerly representing Shares presented to the Surviving Corporation
or Paying Agent shall be canceled and exchanged for the Merger Consideration, as
provided in this Article II, subject to applicable law in the case of Dissenting
Shares.
 
                                        6
   10
 
     2.14  Supplementary Action. If at any time after the Effective Time, any
further assignments or assurances in law or any other things are necessary or
desirable to vest or to perfect or confirm of record in the Surviving
Corporation the title to any property or rights of either the Company or
Purchaser, or otherwise to carry out the provisions of this Agreement, the
officers and directors of the Surviving Corporation are hereby authorized and
empowered, in the name of and on behalf of the Company and Purchaser, to execute
and deliver any and all things necessary or proper to vest or to perfect or
confirm title to such property or rights in the Surviving Corporation, and
otherwise to carry out the purposes and provisions of this Agreement.
 
     2.15  Lost, Stolen or Destroyed Certificates. In the event any Certificates
evidencing Shares shall have been lost, stolen or destroyed, the Paying Agent
shall pay to such holder the Merger Consideration required pursuant to Section
2.10, in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof with such assurances
as the Paying Agent, in its discretion and as a condition precedent to the
payment of the Merger Consideration, may reasonably require of the holder of
such lost, stolen or destroyed Certificates.
 
     2.16  Company Stock Options.
 
     (a) The Company shall take all commercially reasonable actions, if any,
necessary to provide that at the Effective Time, (i) each option outstanding at
the Effective Time to purchase Shares (an "Option") granted under (A) the
Company's 1986 Stock Option Plan, 1995 Stock Option Plan or 1995 Director Option
Plan or (B) any other stock-based incentive plan or arrangement of the Company,
excluding any options granted under the Company's 1995 Employee Stock Purchase
Plan (the "Stock Option Plans"), shall be canceled and (ii) in consideration of
such cancellation, each holder of an Option shall receive in consideration
thereof an amount (subject to any applicable withholding tax) in cash equal to
the product of (x) the excess, if any, of the Merger Consideration over the per
Share exercise price of such Option and (y) the number of Shares subject to such
Option. The Company shall use all commercially reasonable efforts to effectuate
the foregoing, including, if necessary, amending the Stock Plans and obtaining
any necessary consents from holders of Options.
 
     (b) Except as may be otherwise agreed to by Parent or Purchaser and the
Company or as otherwise contemplated or required to effectuate this Section
2.16, the Stock Plans shall terminate as of the Effective Time and the
provisions in any other plan, program or arrangement providing for the issuance
or grant of any other interest in respect of the capital stock of the Company or
any of its Subsidiaries shall be deleted as of the Effective Time. The Company
shall take all actions necessary to provide that as of the Effective Time no
holder of Options under the Stock Plans will have any right to receive shares of
common stock of the Surviving Corporation upon exercise of any such Option.
 
     (c) The Company shall take all commercially reasonable actions, if any,
necessary to provide that at or immediately prior to the Effective Time, (i)
each then outstanding option under the Company's 1995 Employee Stock Purchase
Plan (the "Stock Purchase Plan") shall automatically be exercised and (ii) in
lieu of the issuance of Certificates, each participant shall receive an amount
in cash (subject to any applicable withholding tax) equal to the product of (x)
the number of Shares otherwise issuable upon such exercise and (y) the Merger
Consideration. The Company shall use all commercially reasonable efforts to
effectuate the foregoing, including without limitation amending the Stock
Purchase Plan and obtaining any necessary consents from participants in the
Stock Purchase Plan. The Company (i) shall not permit the commencement of any
new offering period under the Stock Purchase Plan following the date hereof,
(ii) shall not permit any participant to increase his or her rate of
contributions under the Stock Purchase Plan following the date hereof, (iii)
shall terminate the Stock Purchase Plan as of the Effective Time, and (iv) shall
take any other actions necessary to provide that as of the Effective Time no
holder of options under the Stock Purchase Plan will have any right to receive

option.
 
     (d) In the event that an employee of the Company who is a holder of Options
is terminated by the Company after the date of this Agreement but prior to the
Effective Time, such employee shall receive at the Effective Time with respect
to all Options held by such employee as of the date of such termination of
 
                                        7
   11
 
employment the cash payment determined in accordance with Section 2.16(a) that
such employee would have received had such employee been employed as of the
Effective Time.
 
     2.17  Company Warrants. The Company shall take all commercially reasonable
actions, if any, necessary to provide that at the Effective Time, each warrant
outstanding at the Effective Time to purchase Shares (a "Warrant") shall be
canceled. The Company shall take all commercially reasonable efforts to

obtaining any necessary consents from holders of Warrants.
 
                                  ARTICLE III
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
     Except as set forth on the disclosure schedule delivered by the Company to
Parent prior to the execution of this Agreement (the "Company Disclosure
Schedule"), the Company represents and warrants to Parent and Purchaser as
follows:
 
     3.1  Organization, Standing and Corporate Power. Each of the Company and
its Subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction in which it is organized and, except
as would not have a Material Adverse Effect, has all requisite corporate power
and authority to carry on its Business as now being conducted. Each of the
Company and its Subsidiaries is duly qualified or licensed to do business and is
in good standing in each jurisdiction in which the nature of its Business or the
ownership, leasing or operation of its properties makes such qualification or
licensing necessary, other than in such jurisdictions where the failure to be so
qualified or licensed or to be in good standing would not have a Material
Adverse Effect on the Company. The Company has delivered or made available to
Parent complete and correct copies of its Restated Articles of Incorporation and
Bylaws, in each case as amended to the date hereof.
 
     3.2  Subsidiaries. The Company Disclosure Schedule sets forth in Section
3.2 a complete list of the Company's Subsidiaries. All the outstanding shares of
capital stock of, or other equity interests in, each such subsidiary have been
validly issued and are fully paid and nonassessable and are owned directly by
the Company, free and clear of all pledges, claims, liens, charges, encumbrances
and security interests of any kind or nature whatsoever (collectively, "Liens")
and free of any other restriction (including any restriction on the right to
vote, sell or otherwise dispose of such capital stock or other ownership
interests). Except as set forth in Section 3.2 of the Company Disclosure
Schedule, the Company does not own any significant equity interest in any
corporation or other entity.
 
     3.3  Capital Structure.
 
     (a) The authorized capital stock of the Company consists of 50,000,000
shares of Company Common Stock and 5,000,000 shares of preferred stock, no par

309,397 shares of Company Common Stock were reserved for issuance pursuant to
the Stock Purchase Plan, (v) 1,140,284 shares of the Company Common Stock were
reserved for issuance upon exercise of an outstanding Warrant and (vi) 50,000
shares of Series A Participating Preferred Stock, no par value per share, were
reserved for issuance in connection with the Company's Preferred Shares Rights
Agreement dated November 25, 1996 (the "Rights Agreement"). Except as set forth
above, at the close of business on May 20, 1998, no shares of capital stock or
other voting securities of the Company were issued, reserved for issuance or
outstanding. All outstanding shares of capital stock of the Company are, and all
shares which may be issued pursuant to the Stock Option Plans and the Stock
Purchase Plan will be, when issued in accordance with the terms thereof, duly
authorized, validly issued, fully paid and nonassessable and not subject to
preemptive rights. There are no bonds, debentures, notes or other indebtedness
of the Company having the right to vote
 
                                        8
   12
 
(or convertible into securities having the right to vote) on any matters on
which shareholders of the Company may vote. Except as set forth above, there are
no securities, options, warrants, calls, rights, commitments, agreements,
arrangements or undertakings of any kind to which the Company or any of its
Subsidiaries is a party, or by which the Company or any of its Subsidiaries is
bound, obligating the Company or any of its Subsidiaries to issue, deliver or
sell, or cause to be issued, delivered or sold, additional shares of capital
stock or other voting securities of the Company or any of its Subsidiaries or
obligating the Company or any of its Subsidiaries to issue, grant, extend or

and accurate list, as of the date hereof, of: (i) all Options outstanding under
the Stock Option Plans (ii) all Warrants outstanding for the purchase of Shares,
(iii) the per Share exercise price of all such Options and Warrants, as adjusted
pursuant to the provisions of the respective Stock Option Plans and Warrant, and
(iv) the number of Shares subject to issuance upon exercise of all such Options
and Warrants, as adjusted pursuant to the provisions of the respective Stock
Option Plans and Warrant. The Company has not reduced the per Share exercise
price of the Options or Warrant, due to a reduction in the fair market value of
the Shares or otherwise, or established an option exchange program with respect
to any Stock Option Plan or Warrant.
 
     3.4  Authority; Noncontravention. The Company has all requisite corporate
power and authority to enter into this Agreement and, subject to the approval of
the Merger and the adoption of this Agreement by the affirmative vote of the
holders of a majority of the Shares (the "Company Shareholder Approval"), to
consummate the transactions contemplated by this Agreement. The execution and
delivery of this Agreement by the Company and the consummation by the Company of
the transactions contemplated by this Agreement have been duly authorized by all
necessary corporate action on the part of the Company, subject, in the case of
this Agreement, to the Company Shareholder Approval. This Agreement has been
duly executed and delivered by the Company and, assuming due and valid
authorization, execution and delivery hereof by Gambrinus, Parent and Purchaser,
constitutes a valid and binding obligation of the Company, enforceable against
the Company in accordance with its terms, except that (i) such enforcement may
be subject to applicable bankruptcy, insolvency or other similar laws, now or
hereafter in effect, affecting creditors' rights generally, and (ii) the remedy
of specific performance and injunctive and other forms of equitable relief may
be subject to equitable defenses and to the discretion of the court before which
any proceedings therefor may be brought. The execution and delivery of this
Agreement do not, and the consummation by the Company of the transactions
contemplated by this Agreement and compliance by the Company with the provisions
of this Agreement will not, conflict with, or result in any violation of, or
default (with or without notice or lapse of time, or both) under, or give rise
to a right of termination, cancellation or acceleration of any material
obligation or to loss of a material benefit under, or result in the creation of
any material Liens in or upon any of the properties or assets of the Company or
any of its Subsidiaries under, any provision of (i) the Restated Articles of
Incorporation or Bylaws of the Company or the comparable organizational
documents of any of its Subsidiaries, (ii) any loan or credit agreement, note,
bond, mortgage, indenture, lease or other agreement, instrument, permit,

Subsidiaries or any of their respective properties or assets or (iii) subject to
the governmental filings and other matters referred to in the following
sentence, any (A) statute, law, ordinance, rule or regulation or (B) judgment,
order or decree applicable to the Company or any of its Subsidiaries or any of
their respective properties or assets, other than, in the case of clause (iii),
any such conflicts, violations, defaults, rights, losses or Liens that would not
have a Material Adverse Effect on the Company. No consent, approval, order or
authorization of, or registration, declaration or filing with, any Federal,
state or local government or any court, administrative agency or commission or
other governmental authority or agency, domestic or foreign (a "Governmental
Entity"), is required by or with respect to the Company or any of its
Subsidiaries in connection with the execution and delivery of this Agreement by
the Company or the consummation by the Company of the transactions contemplated

and Gambrinus is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction in which it is incorporated and has
all requisite corporate power and authority to carry on its business as now

good standing or to have such power and authority would not have a material
adverse effect on Parent, Purchaser or Gambrinus. Each of Parent, Purchaser and
Gambrinus is duly qualified or licensed to do business and is in good standing
in each jurisdiction in which the nature of its business or the ownership,
leasing or operation of its properties makes such qualification or licensing
necessary, other than in such jurisdictions where the failure to be so qualified

on Parent, Purchaser or Gambrinus. Parent has delivered or made available to the
Company complete and correct copies of its Certificate of Incorporation and
By-Laws and the Certificate of Incorporation and Bylaws of Purchaser, in each
case as amended to the date hereof.

Purchaser and Gambrinus and assuming due and valid authorization, execution and

each such party, enforceable against each such party in accordance with its
terms, except that (i) such enforcement may be subject to applicable bankruptcy,
insolvency or other similar laws, now or hereafter in effect, affecting
creditors' rights generally, and (ii) the remedy of specific performance and
injunctive and other forms of equitable relief may be subject to equitable
defenses and to the discretion of the court before which any proceedings
therefor may be brought. The execution and delivery of this Agreement do not,

contemplated by this Agreement and compliance with the provisions of this
Agreement will not, conflict with, or result in any violation of, or default
(with or without notice or lapse of time, or both) under, or give rise to a
right of termination, cancellation or acceleration of any obligation or to loss
of a material benefit under, or result in the creation of any Liens in or upon
any of the properties or assets of Parent, Purchaser or Gambrinus under, any
provision of (i) the Certificate of Incorporation or Bylaws of Parent, Purchaser
or Gambrinus, (ii) any loan or credit agreement, note, bond, mortgage,
indenture, lease or other agreement, instrument, permit, concession, franchise
or license applicable to Parent, Purchaser or Gambrinus or their respective
properties or assets or (iii) subject to the governmental filings and other
matters referred to in the following sentence, any (A) statute, law, ordinance,
rule or regulation or (B) judgment, order or decree applicable to Parent,
Purchaser or Gambrinus or any of their respective properties or assets, other
than, in the case of clauses (ii) and (iii), any such conflicts, violations,
defaults, rights or Liens that would not have a material adverse effect on
Parent. No consent, approval, order or authorization of, or registration,
declaration or filing with, any Governmental Entity is required by or with
respect to Parent, Purchaser or Gambrinus in connection with the execution and
delivery of this Agreement by Parent,
 
                                       16

transactions contemplated by this Agreement, except for (1) filings, permits,
authorizations, consents and approvals as may be required under the HSR Act, (2)
the filing with the SEC of such reports under the Exchange Act as may be
required in connection with this Agreement and the transactions contemplated by
this Agreement, (3) the filing of an agreement of merger with the Secretary of
State pursuant to the GCL and appropriate documents with the relevant
authorities of other states in which the Company is qualified to do business,

securities, "blue sky" or takeover laws, (5) compliance with any applicable
requirements of the Exchange Act and (6) such other consents, approvals, orders,
authorizations, registrations, declarations and filings, the failure of which to
be obtained or made would not have a material adverse effect on Parent.
 
     4.3  Information in Proxy Statement. None of the information supplied by
Parent, Purchaser or Gambrinus in writing expressly for inclusion or
incorporation by reference in the Proxy Statement (or any amendment thereof or
supplement thereto) will, at the date mailed to shareholders and at the time of

required to be stated therein or necessary in order to make the statements made
therein, in light of the circumstances under which they are made, not
misleading.

purpose of engaging in the transactions contemplated hereby, has engaged in no
other business activities and has conducted its operations only as contemplated
hereby.

have available all the funds necessary to perform their respective obligations
under this Agreement, including without limitation payment in full for all
Shares outstanding at the Effective Time and the payment of all expenses in
connection herewith. Parent and Purchaser have received, and have furnished to
the Company, true and complete copies of the written commitment from a third
Person (the "Financing Commitment") with respect to the financing of the Merger
(the "Financing"). The aggregate proceeds of the Financing, together with
internal corporate funds of Parent, Purchaser or Gambrinus, are sufficient to
acquire all of the Shares in the Merger and to pay anticipated expenses in
connection therewith. The Financing Commitment is valid, binding and enforceable
in accordance with their terms and have not been revoked as of the date hereof.
Nothing has come to the attention of Parent, Purchaser or Gambrinus which would
cause either Parent or Purchaser to believe that the proceeds of the Financing
will not be available to them at the Effective Time. Parent will not enter into
any amendments or supplements to the Financing Commitment that would materially
reduce the likelihood of obtaining the Financing.
 
     4.7  Share Ownership. Neither Parent, Purchaser nor Gambrinus are the
beneficial owner of any shares of capital stock of the Company.

     5.2  No Solicitation.
 
     (a) From the date of this Agreement until the earlier of termination of
this Agreement or the Effective Time, the Company shall not, nor shall it
authorize or permit any of its officers, directors or employees or any
investment banker, financial advisor, attorney, accountant or other
representative or agent retained by it to, directly or indirectly, (i) solicit,
initiate or knowingly encourage the submission of any Takeover Proposal (as
defined below) or (ii) participate in any discussions or negotiations regarding,
or furnish to any person any nonpublic information with respect to, or take any
other action designed or reasonably likely to facilitate any inquiries or the
making of any proposal that constitutes a Takeover Proposal; provided, however,
that if, at any time prior to the Effective Time, the Company Board of Directors
determines in good faith, after consultation with outside counsel, that it is
necessary to do so in order to comply with its fiduciary duties to the Company's
shareholders under applicable law, the Company may, in response to a Takeover
Proposal which was not solicited subsequent to the date hereof, and subject to
compliance with Section 5.2(c), (x) furnish information with respect to the
Company to any person pursuant to a confidentiality agreement with terms no more
favorable to such person than the terms of the Confidentiality Agreement (as
hereinafter defined) and (y) participate in discussions and negotiations
regarding such Takeover Proposal. For purposes of this Agreement, "Takeover
Proposal" means any inquiry, proposal or offer from any person relating to any
direct or indirect acquisition or purchase of a substantial amount of assets of
the Company and its Subsidiaries taken as a whole (other than inventory in the
Ordinary Course of Business), or more than a 20% interest in the total voting
securities of the Company or any tender offer or exchange offer that if
consummated would result in any person beneficially owning 20% or more of any
class of equity securities of the Company or any merger, consolidation, business
combination, sale of substantially all assets, recapitalization, liquidation,
dissolution or similar transaction involving the Company, other than the
transactions contemplated by this Agreement.
 
     (b) Except as set forth in this Section 5.2, neither the Company Board of
Directors nor any committee thereof shall (i) withdraw or modify, or propose
publicly to withdraw or modify, in a manner adverse to Parent, the approval or
recommendation by such Company Board of Directors or such committee of the
Merger or this Agreement, (ii) approve or recommend, or propose publicly to
approve or recommend, any Takeover Proposal or (iii) cause the Company to enter
into any letter of intent, agreement in principle, acquisition agreement or
other similar agreement (each, an "Acquisition Agreement") related to any
Takeover Proposal. Notwithstanding the foregoing, in the event that prior to the
Effective Time, the Company Board of Directors determines in good faith, after
consultation with outside counsel, that it is necessary to do so in order to
comply with its fiduciary duties to the Company's shareholders under applicable
law, the Company Board of Directors may, in response to an unsolicited Superior
Proposal (as defined below) (subject to the following proviso), (x) withdraw or
modify or propose publicly to withdraw or modify its approval or recommendation
of the Merger or this Agreement, (y) approve or recommend any such Superior
Proposal if concurrently with such approval or recommendation the Company
terminates this Agreement or (z) cause the Company to enter into an Acquisition
Agreement related to any Superior Proposal if concurrently with the execution of
such Acquisition Agreement the Company terminates this Agreement; provided, that
in the case of clauses (y) and (z), only at a time that is after the later of
(i) the second Business Day following Parent's receipt of written notice
advising Parent that the Company Board of Directors has received a Superior
Proposal,
 
                                       19
   23
 
specifying the material terms and conditions of such Superior Proposal and
identifying the person making such Superior Proposal and (ii) in the event of
any amendment to the price or any material term of a Superior Proposal, one
Business Day following Parent's receipt of written notice containing the
material terms and conditions of such amendment (it being understood that each
further amendment to any material terms or conditions of a Superior Proposal
shall necessitate an additional written notice to Parent and an additional one
Business Day period prior to which the Company can take the actions set forth in
clauses (y) and (z) above). For purposes of this Agreement, a "Superior
Proposal" means any bona fide Takeover Proposal made by a third party (i) that
is on terms which the Company Board of Directors determines in its good faith
judgment (based on consultation with a nationally recognized investment banking
firm) to be more favorable to the Company's shareholders than the Merger and
(ii) for which financing, to the extent required, is then committed, or which,
in the good faith judgment of the Company Board of Directors, is capable of
being readily obtained by such third party.
 
     (c) In addition to the obligations of the Company set forth in paragraphs
(a) and (b) of this Section 5.2, the Company shall promptly advise Parent orally
and in writing of any request for nonpublic information (except in the Ordinary
Course of Business and not in connection with a possible Takeover Proposal) or
of any Takeover Proposal known to it, the material terms and conditions of such
request or Takeover Proposal and the identity of the person making such request
or Takeover Proposal. The Company will promptly inform Parent of any change in
the material terms and conditions (including amendments or proposed amendments)
of any such request or Takeover Proposal.
 
     (d) Nothing contained in this Section 5.2 or in any other provision of this
Agreement shall prohibit the Company or the Company Board of Directors from (i)
taking and disclosing to the Company's shareholders a position with respect to a
tender or exchange offer by a third party pursuant to Rule 14d-9 or Rule 14e-2
promulgated under the Exchange Act or (ii) making such disclosure to the
Company's shareholders as, in the good faith judgment of the Company Board of
Directors, after consultation with outside counsel, is necessary for the Company
Board of Directors to comply with its fiduciary duties under applicable law.
 
     (e) The Company agrees that it will immediately cease and cause to be
terminated any existing activities, discussions or negotiations with any parties
conducted prior to the date of this Agreement with respect to any Takeover
Proposal.

commitments and records and, during such period, the Company shall, and shall
cause each of its Subsidiaries to, make available promptly to Parent upon
request (a) a copy of each report, schedule, registration statement and other
document filed or received by it during such period pursuant to the requirements
of the federal or state securities laws or the federal Tax laws, or state, local

apply to all information about the Company which has been furnished under this

to be done, and to assist and cooperate with the other parties in doing, all
things necessary, proper or advisable to consummate and make effective, in the
most expeditious manner practicable, the Merger and the other transactions

comparable merger notification laws of non-U.S. jurisdictions and to respond as
promptly as practicable to any inquiries received from the Federal Trade
Commission and the Antitrust Division of the Department of Justice or the
authorities of such other jurisdiction for additional information or
documentation and to respond as promptly as practicable to all inquiries and

Time any further action is necessary or desirable to carry out the purposes of

respect at any time from the date hereof to the Effective Time or (y) any
condition to Closing set forth in Article VII to be unsatisfied in any material
respect at any time from the date hereof to the Effective Time (except to the

equivalent coverage and amounts, including extension or tail coverage policies,
containing terms substantially as favorable to such former directors or
officers; provided, further, that if the existing D&O Insurance expires, is
terminated or canceled during such period, Parent or the Surviving Corporation
will use all reasonable efforts to obtain substantially similar D&O Insurance
coverage; provided, further, however, that in no event shall Parent be required
to pay aggregate premiums for insurance under this Section 6.6(b) in excess of
150% of the average of the aggregate premiums paid by the Company in 1995, 1996
and 1997 on an annualized basis for such purpose (the "Average Premium"), which
true and correct amounts are set forth in Section 6.6(b) of the Company
Disclosure Schedule; and provided, further, that if Parent or the Surviving
Corporation is unable to obtain the amount of insurance required by this Section
6.6(b) for such aggregate premium, Gambrinus, Parent or the Surviving
Corporation shall obtain as much insurance as can be obtained for an annual
premium not in excess of 150% of the Average Premium.

chief financial officer. The quarterly Interim Financial Statements shall comply
as to form in all material respects with applicable accounting requirements and
the published rules and regulations of the SEC with respect thereto, shall have

        willful breach of representation or warranty under this Agreement by
        such party; or
 
             (ii) if a court of competent jurisdiction or any other Governmental
        Entity shall have issued an order, decree or ruling or taken any other
        action permanently enjoining, restraining or otherwise prohibiting the
        acceptance for payment of, or payment for, Shares pursuant to the Merger

     breach or failure to perform in any material respect by Gambrinus, Parent
     or Purchaser of any representation, warranty, covenant or other agreement
     contained in this Agreement which breach or failure to perform (i) results
     in the failure of a condition set forth in Section 7.2 (e) or (f) above and
     (ii) is not reasonably capable of being cured prior to the earlier of: (a)
     within 15 Business Days after the giving of written notice thereof or (b) 2
     Business Days prior the Cut-Off Date.

duly authorized action taken, at any time before or after obtaining the Company
Shareholder Approval, but after the Company Shareholder Approval, no amendment

except by an instrument in writing signed on behalf of each of the parties
hereto.
 
     8.4  Extension; Waiver. At any time prior to the Effective Time, the

rights under this Agreement or otherwise shall not constitute a waiver of those
rights.

        WHEREAS, as an inducement and a condition to entering into the Merger
Agreement, Parent has requested that the Stockholder agree, and the Stockholder

party shall not preclude the simultaneous or later exercise of any such right,
power or remedy by such party.

power or remedy provided under this Agreement or otherwise available in respect
hereof at law or in equity, or to insist 



                                      -10-
   44

upon compliance by any other party hereto with its obligations hereunder, and
any custom or practice of the parties at variance with the terms hereof, shall
not constitute a waiver by such party of its right to exercise any such or other
right, power or remedy or to demand such compliance.

beneficiary of, and entitled to enforce, the provisions contained in Section

accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in any court of the United States
located in the State of California or in any California state court, this being
in addition to any other remedy to which they are entitled at law or in equity.
