                                       14

 
with respect to any material provision contained in any insurance policy, and
the Company has not failed to give any notice or present any claim under any
insurance policy in due and timely fashion. All such policies are valid and
enforceable by the Company and in full force and effect, and are sufficient in
nature, scope and amounts to insure adequately the Company's business,
properties, assets and risks.

  3.21  Powers of Attorney; Bank Accounts.  Except as set forth in Schedule
        ---------------------------------                          --------

  3.22  Tax Returns.  The provision for taxes shown on the most recent Financial
        -----------                                                             
Statements was sufficient to satisfy all income, gross receipts, franchise,
excise, license, employment, occupation, environmental, capital stock, profits,
registration, value added, sales and use taxes, or other tax of any kind
whatsoever, governmental charges, duties, penalties, interest and fines due or
which might lawfully be due, to the United States or any foreign taxing
authority or any state, county, city or agency of any of the foregoing ("Taxes")
and all assessments received by the Company for all periods ended on or prior to
the date of the most recent Financial Statements.  As of the date hereof, no
Taxes payable by Sellers or the Company are past due, no tax liabilities have
been assessed or proposed which remain unpaid, and neither Sellers nor the
Company is aware of any basis upon which any assessment for additional Taxes
could be made against Sellers or the Company.  In addition, neither Sellers nor
the Company has signed any extension agreement with the Internal Revenue Service
or any other government entity or taxing authority or given a waiver of a
statute of limitations with respect to the payment of Taxes.  Sellers and the
Company have filed or obtained extensions of time to file all income tax returns
and all state, local and foreign income, franchise, sales, use, excise or
similar tax returns and all real property tax returns which were required to be
filed as of the date of this Agreement, and until the Closing Date will timely
file or obtain extensions of time to file all returns which were not required to
be filed prior to the date hereof. All tax returns that Sellers or the Company
was required to file were correct and complete in all respects.  The information
shown on the Federal income tax returns of the Company heretofore delivered to
Buyer is accurate and complete in all material respects and fairly presents the
information purported to be shown.  Except as described in Schedule 3.22 as to
                                                           -------------      
the date, scope, nature and resolution thereof, the Federal income tax returns
of the Company have not been examined by the Internal Revenue Service or any
state governmental body since September 30, 1993.  Except as described in
                                                                         
Schedule 3.22, there are no suits, actions, claims, investigations, inquiries or
- -------------                                                                   
proceedings now pending or, to Sellers' knowledge, threatened against Sellers or
the Company, nor are there any matters under discussion with any 

                                       15

 
governmental authority relating to Taxes, nor are there any claims which might
reasonably be asserted by any such authority for payment of additional Taxes.
There are no liens or security interests on any of the assets of the Company or
Sellers that arose in connection with any failure (or alleged failure) to pay
any Taxes. The Company has, and at the Closing will have, paid all unemployment
and disability contributions due and owing, and will have accrued for any
amounts not yet due and owing, in respect of services rendered by employees of
the Company. All Taxes or other amounts which the Company is required by law to
withhold or collect have been duly withheld or collected and to the extent
required have been paid over to the proper governmental authorities on a timely
basis or if not yet due, properly reflected as an obligation on the most recent
Financial Statements. The Company has not filed a consent under Sec. 341(f) of
the Internal Revenue Code of 1986, as amended (the "Code") concerning
collapsible corporations. The Company has not made any payments, nor is
obligated to make any payments, nor is a party to any agreement that under
certain circumstances could obligate it to make any payments that will not be
deductible under Code Sec. 280G. The Company is not and has not been a United
States real property holding corporation within the meaning of Code Sec.
897(c)(2) during the applicable period specified in Code Sec. 897(c)(1)(A)(ii).
The Company is not and has never been a party to any tax allocation or sharing
agreement. The Company (a) has never been a member of an affiliated group filing
a consolidated Federal income tax return, or (b) has any liability for the Taxes
of any Person under Treas. Reg. Section 1.1502-6 (or any similar provision of
state, local or foreign law), as a transferee or successor, by contract, or
otherwise.

  3.23  Liabilities.  Except as disclosed on Schedule 3.23, the Company does not
        -----------                          -------------                      
have any debts or liabilities of any nature, whether accrued or not, absolute or
contingent, due or to become due or otherwise, and there is no basis for
assertion against the Company of claims for any debts or liabilities, other than
(i) those set forth on its most recent Financial Statements; and (ii)
liabilities subsequently incurred in the ordinary course of business which are
not in the aggregate material.  No event has occurred which constitutes, or
which with the giving of notice or the passage of time or both would constitute,
a material breach or default in respect of the terms or conditions of any such
liability and no waiver or forbearance has been granted by any holder of any
such liability with respect thereto.

  3.24  Books and Records.  The Company has at all times since January 1, 1996,
        -----------------                                                      
kept full and complete financial books and records and has recorded all
transactions which should be set forth and reflected, all in accordance with
generally accepted accounting principles and past practices of the Company
consistently applied, and the Company will continue to do so, without variation
in method or procedure until and including the Closing Date.

  3.25  Conflicts of Interest.  Neither Sellers nor any other officer, director
        ---------------------

than for services as officers, directors and employees), including, without
limitation, any loan or guarantee, or any contract, agreement or other
arrangement providing for the furnishing of services or goods to or by, or
otherwise requiring payments (directly, indirectly or contingently) to or from,
any officer, director, employee, family member of any of the foregoing, or any
corporation, partnership, trust or other entity in which any such officer,
director, employee or family member has an interest or is an officer, director,
trustee or partner. Neither Sellers nor the Company nor any officer, director,
employee, or family member of the foregoing, owns, directly or indirectly, any
interest in, or is a director, officer or employee of, any corporation,
partnership, firm, association or business organization, entity or enterprise
which is a competitor, potential competitor, supplier or customer of the
Company, nor is in any way associated with or involved in a business similar to
that conducted by the Company, provided that ownership of not more than one
percent (1%) of the capital stock of any corporation listed on a national
securities exchange shall not be deemed to be ownership of an interest in such
corporation for purposes of this Section 3.25. Neither Sellers nor the Company
nor any officer, director, employee or family member of any of the foregoing,
owns, or has any claim, right or interest in or to, directly or indirectly, in
whole or in part, any property, asset or right, tangible or intangible
(including without limitation, any patent, trademark, tradename, brand name,
copyright, pending application for any patent, trademark or copyright, any
invention, process, know-how, formula, pattern, design or trade secret), which
the Company is presently using or the use of which is necessary or proper for
its business.

  3.26  ERISA.  The Company has complied and currently is in compliance, both as
        -----                                                                   
to form and operation, with the applicable provisions of the Employee Retirement
Security Act of 1974, as amended ("ERISA"), the Internal Revenue Code of 1986,
as amended (the "Code") and all other applicable laws with respect to each
Employee Benefit Plan (and related trust, insurance contract, or fund) or any
material fringe benefit plan or program which is maintained or has been
established by the Company or to which the Company contributes or is required to
contribute.  Schedule 3.26 lists all Welfare Plans and Pension Plans of the
             -------------                                                 
Company currently in effect.  All documents, reports, descriptions and
statements with respect to any Pension Plan or Welfare Plan which are required
to be filed with any government agency have been timely filed or have been
timely distributed to the appropriate persons and correct and complete copies
have been delivered to Buyer.  Each Pension Plan and related trust are qualified
within the meaning of Sections 401(a) and 501(a) of the Code, respectively.
With respect to each Pension Plan, a favorable determination letter as to
qualification under Section 401(a) of the Code has been obtained by the Company
and copies thereof have been forwarded to Buyer.  With respect to any Pension
Plan or any Welfare Plan, neither the Company nor any fiduciary of any such plan
(as described in Section 21(A) of ERISA) has been engaged in any transaction in
violation of Section 404 of ERISA, Section 406 of ERISA (for which no exemption
exists under Section 408 of ERISA), or Section 4975(c)(1) of the Code (for which
no exemption exists under Section 4975(c)(2) or (d) of the Code) which 

                                       17

 
would subject the Company or any such fiduciary to any tax, penalty or liability
under Section 4098 of ERISA or Section 4975 of the Code. The Company has timely
made all contributions required under the terms of any Pension Plan, any Welfare
Plan and any related agreement. The fair market value of the assets held to fund
any Pension Plan which is a defined benefit plan as defined in Section 3(35) of
ERISA as of September 30, 1998, exceeds the actuarial present value of all
accrued benefits (both vested and non-vested) under such Pension Plan as of
September 30, 1998, and such valuation has been determined in accordance with
the Pension Benefit Guaranty Corporation ("PBGC") methods, factors and
assumptions applicable thereto. No Pension Plan has an accumulated funding
deficiency as defined in Section 302 of ERISA or Section 412 of the Code,
whether or not waived and each Pension Plan has been funded in accordance with
the minimum funding standards of ERISA and the Code. The Company has paid all
premiums (and interest charges and penalties for late payment, if applicable)
due PBGC with respect to each Pension Plan subject to Title IV of ERISA. A
Reportable Event referred to in Section 4043(b) of ERISA has not occurred with
respect to any Pension Plan subject to Title IV of ERISA. The Company has taken
no action and has not made any filing with the PBGC or the Internal Revenue
Service to terminate any Pension Plan. Neither Gerrans nor the Company has any
knowledge of any event or condition referred to in Section 4042(a) or 4043 of
ERISA which presents a material risk of termination of any Pension Plan by the
PBGC. No proceeding or other action has been initiated (or threatened) by the
PBGC to terminate any Pension Plan, and no written notice has been given to
Gerrans or the Company of an intention to commence or seek commencement of any
such proceeding or action. The Company does not maintain or contribute or has
ever maintained or contributed to any Welfare Plan for current or future retired
or terminated employees, their spouses or dependents (other than in accordance
with Code Section 4980B). For purposes of this Section, Employee Benefit Plan
means any qualified or non-qualified employee welfare benefit plan (as defined
in Section 3(1) of ERISA ("Welfare Plan")) and each employee pension benefit
plan (as defined in Section 3(2) of ERISA ("Pension Plan")).

        --------------------------------------------------

Agreement, the Transaction Documents or the consummation of the transactions
contemplated hereby or thereby, as applicable.

  3.28  Broker's Fees.  Sellers have not paid, nor have Sellers become obligated
        -------------

realtor, finder or intermediary for or on account of the transactions
contemplated herein.

        -------------                                                  
authorizations which are or will be required in respect of the 

                                       18

 
Company under all Federal, state and local laws, rules, regulations, ordinances,

such required permits, licenses and authorizations, and all other limitations,
restrictions, conditions, standards, prohibition, requirements, obligations,
schedules and timetables contained in the Environmental Laws. There is no
pending civil or criminal litigation, notice of violation or administrative
proceeding relating in any way to the Environmental Laws (including without
limitation, notices, demand letters or claims under any Environmental Laws) with
respect to the Company. Sellers do not suspect or believe that any civil or
criminal litigation, notice of violation or administrative action relating in
any way to the Environmental Laws with respect to the Company is threatened.
There have not been and there are not any past or present events, conditions,
circumstances, activities, practices, incidents or actions which could
reasonably be expected to interfere with or prevent continued compliance with
any Environmental Law as in effect on the date hereof by the Company or which
may give rise to any legal liability, or otherwise form the basis of any claim,
action, suit, proceeding, hearing or investigation against or involving the
Company based on any violation or alleged violation of any Environmental Law.
Schedule 3.29 contains a complete description of all past and current practices,
- -------------
contracts and agreements of the Company for disposal of materials and wastes

manufactured, nor is there any basis for any such action, suit, inquiry,
proceeding or investigation (whether or not such action, suit, inquiry,
proceeding or investigation would be barred by workers compensation or similar
laws).

  3.31  Information Technology Systems; Year 2000 Compliance.  Except as
         ----------------------------------------------------            
described on Schedule 3.31, the Company's information technology systems are in
             -------------                                                     
good operation, condition and repair, capable of performing the functions for
which such systems are currently and normally used by the Company and all
required maintenance has been consistently performed with such systems.  The
Company possesses all software licenses necessary to conduct the Business as

                                                         -------------

account and for investment purposes only and not with the view to, or for resale
in connection with, any distribution thereof.  Gerrans understands that the Bolt
Stock he is acquiring is characterized as "restricted securities" under the
federal securities law inasmuch as they are being acquired from Buyer in a
transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under
the Securities Act of 1933 (the "Act") only in certain limited circumstances.

                                       20

Gerrans further acknowledges the he has had the opportunity to ask Buyer's
management questions about Buyer's business and financial condition and that
Gerrans has obtained such information as requested to the extent deemed
necessary by Gerrans to permit Gerrans to fully evaluate the merits and risks of
an investment in Buyer.  Further Gerrans has consulted with such other of its
investment and/or accounting and/or legal and/or tax advisors as Gerrans has
deemed necessary and appropriate in making the decision to acquire the Bolt
Stock.

an environmental audit conducted of the real properties, facilities and
equipment utilized by the Company and to have Deloitte & Touche LLP, or another

information which Buyer received from a third party legally entitled to transfer
it. In the event of termination of this Agreement, upon Sellers' written
request, Buyer and its authorized representatives will promptly return any such

Agreement preclude Buyer from taking such steps as may be necessary to purchase
a competitor of the Company in the event the transaction contemplated by this
Agreement is not consummated.

  6.2  Operation of the Business of the Company.  Sellers agree to conduct the
       ----------------------------------------

maintain the financial condition of the Company substantially consistent with
that reflected in the Financial Statements, not to enter into any extraordinary
transaction or make any transfer (except in the ordinary course of business) or
distribution of Company assets, to preserve intact its present business
organization, to take reasonable steps to keep available the services of its
officers and employees and to maintain satisfactory relationships with
licensors, licensees, suppliers, contractors, distributors, customers and others
having business relations with it.  Without limiting the generality of the

                                       24

 
foregoing, and except as otherwise expressly provided this Agreement or with the
prior written consent of Buyer, Sellers and the Company agree that the Company

ordinary course of business consistent with past practices, or (iii) make any
loans, advances or capital contributions to, or investments in, any other
person;

       (f) (i) increase in any manner the compensation for any of its directors,

option, stock appreciation right, group insurance, severance pay, retirement or
other employee benefit plan, agreement or arrangement, or to any employment or

the benefit of any person, or to amend any of such plans or any of such
agreements in existence on the date hereof;

       (g) permit any of its current insurance policies to be canceled or
terminated or any of the coverage thereunder to lapse, unless simultaneously
with such termination, cancellation or lapse, replacement policies are in full
force and effect providing coverage equal to or greater than the coverage under
those canceled, terminated or lapsed for substantially similar premiums;

       (h) amend or terminate any lease or, except in the ordinary course of

       --------                                                                
(including, without limitation, the fees and expenses of its accountants,
agents, representatives and counsel) incident to the negotiation, preparation
and carrying out of this Agreement and necessary to its performance of and
compliance with all agreements and conditions contained herein or with respect
to any other aspect of the transactions contemplated 

                                       26

 
by this Agreement, regardless of whether the transactions contemplated hereby
are consummated.

  6.4  Taxes.  Sellers shall pay any and all income, sales, transfer, conveyance
       -----                                                                    
or documentary taxes of any sort imposed by a governmental authority on or in
connection with the sale or transfer of the Stock from Sellers to Buyer and
shall cause any appropriate stock transfer stamps to be affixed at the Closing
to the certificates evidencing the Stock transferred hereunder.

  6.5  Parties to be Reasonable; Termination.  Each of the parties hereto agrees
       -------------------------------------                                    
to use its best efforts to cause the preconditions to the Closing to occur in a
timely fashion, and to prevent the conditions permitting any party to withdraw
from occurring.  If the Closing does not occur on or prior to April 20, 1999,
this Agreement may be terminated by either Buyer or Sellers except that (a)
Buyer may not so terminate if its willful act or failure to act with the
intention of unreasonably preventing the Closing from occurring on or prior to
such date prevented the occurrence of the Closing on or prior to such date, and
(b) Sellers may not so terminate if his willful act or failure to act with the
intention of preventing the Closing from occurring on or prior to such date
prevented the occurrence of the Closing on or prior to such date.  The party
asserting his or its right to terminate this Agreement shall give notice thereof
to the other party to this Agreement stating the grounds therefor.  Nothing
herein shall relieve any party from liability for a breach of its obligations
under this Agreement.

  6.6  Notice of Changes.  Until the Closing, Sellers shall notify Buyer of any
       -----------------                                                       
material change in the Business as soon as it become apparent to Sellers that
any such change has or may occur.

  6.7  Preservation of Business.  Until the Closing, the Company will and
       ------------------------                                          
Sellers will cause the Company to use its best efforts to preserve its business
organization intact, and to preserve its goodwill.  Without limiting the
generality of the foregoing, the Company will, and Gerrans will cause the
Company to, timely perform all obligations required of the Company under the
contracts and permits listed on the Schedules to this Agreement.

  6.8  Litigation.  Sellers will promptly notify Buyer of any lawsuits, claims,
       ----------                                                              
proceedings or investigations which are commenced or, to Sellers' knowledge,
threatened by or against the Company, or commenced or, to Sellers' knowledge,
threatened against (i) the Company's affiliates, or against any employee,
consultant or director of the Company or any affiliate, in connection with the
Business, or (ii) Sellers, in connection with any of their assets, including the
Stock.

                                       27

 
  6.9  No Negotiations.  Until the Closing, or the earlier termination of this
       ---------------                                                        
Agreement in accordance with its terms, without the express prior consent of
Buyer, neither the Company, Gerrans nor any of their affiliates, officers,
directors, employees, consultants, advisors, agents, investment bankers, or any
family members of any of the foregoing shall, directly or indirectly, initiate
discussions with, engage in negotiations with, entertain any offer from, or
provide any information to any corporation, partnership, person or other entity
or group involving the possible sale, directly or indirectly, transfer or joint
venture of the Company, the Business or assets or the Stock of the Company to
any person or entity other than Buyer.

  6.10  Financial Statements.  Gerrans acknowledges that audited financial
        --------------------                                              
statements for the fiscal years ended September 30, 1997 and 1998 will need to
be prepared and certified by Buyer's independent certified public accountants
("Buyer's CPAs"), for inclusion in Buyer's Current Report on Form 8-K to be
filed with the Securities and Exchange Commission and thereafter to be
incorporated into Buyer's audited financial statements.  Gerrans agrees that
between the date hereof and the Closing Date, Buyer's CPAs shall be afforded
access to (including copies of ) the Company's books and records and such other
information as Buyer's CPAs reasonably request in order to commence preparation
of such audited financial statements.  At all times during such preparation,
whether before or after the Closing, Gerrans and the Company shall cooperate
fully with Buyer's CPAs, including taking such actions as Buyer's CPAs
reasonably require, in connection with the preparation and certification by
Buyer's CPAs of such audited financial statements.

  6.11  Limitations on Disposition.  The Bolt Stock has not been registered
        --------------------------                                         
under the Act or under applicable state securities laws and, therefore, cannot
be sold, assigned, or otherwise transferred unless it is subsequently registered
under the Act and under applicable state securities laws or an exemption from
such registration is then available.  Gerrans hereby agrees that he will not
sell, assign, or transfer the Bolt Stock unless it is registered under the Act
and under applicable state securities laws or an exemption from such
registration is then available, according to an opinion of Buyer's counsel or
other counsel reasonably acceptable to Buyer.  Gerrans represents that he can
afford to hold the Bolt Stock for an indefinite period of time.

7.  SURVIVAL.
    -------- 

  7.1  Limited Survival of Representations and Warranties.  The representations
       --------------------------------------------------                      
and warranties of the parties contained in Articles 3 and 4 shall survive the
Closing and expire on December 31, 2000, provided that (a) claims, if any,
asserted in writing prior to the expiration of the representation or warranty to
which they related, shall survive until finally resolved and satisfied in full
and (b) claims, if any, which (i) involve the representations set forth in
Section 

                                       28

 
3.29 or otherwise involve environmental matters; (ii) are based on
fraud; (iii) relate to title of the Stock; (iv) relate to any alleged ownership
of or interest in the Stock, the Company or its assets, or matters relating to
any prior ownership interest in the Stock, the Company or its assets; (v) assert
tax liability; or (vi) relate to a product liability claim or other liability of
the Company arising prior to the Closing Date, shall survive for the full period
of the applicable statute of limitations, and until finally resolved and
satisfied in full.  All claims and actions for indemnity for breach of any
representation or warranty shall be asserted or maintained in writing by a party
hereto on or prior to the expiration of such representation or warranty.  Each
of the warranties and representations contained herein is independent of every
other, and no warranty or representation shall in any way limit, restrict,
modify, or be deemed or construed in any way to limit, restrict or modify any
other warranty or representation.  Without limiting the foregoing, each and all
of the foregoing warranties and representations shall survive the consummation
and closing of this transaction and such investigation as Buyer may make,
limited as aforesaid.  The consummation or Closing of this transaction in the
face of any known breach of any warranty or representation contained herein
shall not be, or be deemed or construed to be, a waiver of such breach,
departure, or variation, unless such breach, departure or variation is
specifically identified and waived in writing by the party to which the warranty
or representation was made.

  7.2  Other.  All covenants, agreements and indemnities contained herein shall
       -----                                                                   
survive for the full period of the applicable statute of limitations, and until
finally resolved and satisfied in full, provided however that performance of the
covenants contained in Sections 6.1, 6.2 and 6.5 through 6.9 hereof shall expire
on the Closing Date in accordance with their terms.

8.  RESTRICTIVE COVENANT.
    -------------------- 

  8.1  Non-Competition.  Gerrans agrees that for a period expiring five (5)
       ---------------                                                     
years from the Closing Date (the "Expiration Date"), he will not directly or
indirectly, for his own account or as an employee, officer, director, partner,
joint venturer, shareholder, investor or otherwise, either (i) engage in any
business or enterprise involving manufacturing, distribution, marketing or sale
of any product competitive with those manufactured, distributed, marketed or
sold by the Company in the United States or any province, district, island or
possession located outside the United States in which the Company does business
as of the date hereof through the Expiration Date, (ii) compete with the Company
in any other business in which the Company may be engaged or which it is
actively developing or had developed as of the Expiration Date, or (iii) employ
or solicit the employment or engagement by others of any employees of the
Company or independent contractors (except accountants and attorneys) servicing
the Company or solicit the business of any customers or suppliers of the Company
in a manner which would compete with the Company.  The prohibitions contained
herein shall not prohibit Gerrans from owning (without any further 

                                       29

 
participation or involvement) not more than one percent (1%) of the outstanding
capital stock of any entity listed on a national securities exchange. Gerrans
agrees that he will not disclose to others or use for his own benefit (or cause
or induce others to do the same) any proprietary, confidential or secret
information or documents of the Company (including, without limitation, customer
lists, processes, inventions, methods or products, whether or not patented or
patentable). For purposes of this Section 8.1, "Company" shall include Buyer and
its affiliates.

  8.2  Reasonableness of Restriction.  Gerrans acknowledges that the restricted
       -----------------------------                                           
period of time and geographical area specified under Section 8.1 hereof are
reasonable, in view of the nature of the business in which the Company is
engaged and his knowledge of the Company's business.  The parties intend for
this restriction to be deemed to be a series of separate covenants, one for each
and every county of each and every state of the United States and each and every
province, district, island or possession outside of the United States, to the
extent covered by Section 8.1.

  8.3  Modification of Restrictions.  Notwithstanding anything contained in
       ----------------------------                                        
Section 8.2 to the contrary, if the period of time or the geographical area
specified under Section 8.1 hereof should be determined by a court of competent
jurisdiction to be unreasonable in any judicial proceeding, then the parties
agree that the provision shall remain in full force and effect for the greatest
time period and in the greatest area that would not render it unenforceable.

  8.4  Remedies.  Gerrans acknowledges that any breach of this Section 8 will
       --------                                                              
cause Buyer irreparable harm for which there is no adequate remedy at law, and
as a result of this, Buyer shall be entitled to the issuance by court of
competent jurisdiction of an injunction, restraining order or other equitable
relief in favor of itself restraining Gerrans from committing or continuing any
such violation.  Any right to obtain an injunction, restraining order or other
equitable relief hereunder shall not be deemed a waiver of any right to assert
any other remedy Buyer may have at law or in equity.

9.  INDEMNIFICATION.
    --------------- 

  9.1  Indemnification by Sellers and the Company.  Sellers hereby agree to
       ------------------------------------------                          
indemnify, defend and hold Buyer and its affiliates (defined as a person or
entity that directly, or indirectly through one or more intermediaries, controls
or is controlled by, or under common control with Buyer) and their officers,
directors, employees and Sellers, and their successors and assigns, harmless
from and against any and all liabilities, damages, losses, proceedings, suits,
claims, demands, actions, assessments, judgments, costs and expenses (including
without limitation, attorney's fees and disbursements) arising out of, or
resulting from (i) any breach of any warranty or any misrepresentation by
Sellers or the Company, or (ii) the nonperformance or 

                                       30

 
breach of any agreement, covenant or obligation to be performed under this
Agreement on the part of Sellers before or at Closing, or the Company.

  9.2  Indemnification by Buyer.  Buyer hereby agrees to indemnify, defend and
       ------------------------                                               
hold Sellers, and their successors and assigns, harmless from and against any
and all liabilities, damages, losses, claims, proceedings, suits, demands,
actions, assessments, costs and expenses (including without limitation,
attorney's fees and disbursements) arising out of, or resulting from, (i) any
breach of any warranty or any misrepresentation by Buyer, or (ii) the
nonperformance or breach of any agreement, covenant or obligation to be
performed on the part of Buyer under this Agreement.

  9.3  Survival of Indemnification.  It is understood and agreed that these
       ---------------------------                                         
agreements of indemnification shall survive without time limitation, subject to
the provisions of Section 7.1 limiting survival of certain representations and
warranties.

  9.4  Notice and Opportunity to Defend.  Promptly after the receipt by Buyer or
       --------------------------------                                         
Sellers respectively (an "Indemnified Party"), of notice of any claim or the
commencement of any action or proceeding which such Indemnified Party recognizes
gives rise or may give rise to a claim against the other party (the
"Indemnitor") under this Section 9, the Indemnified Party shall give the
Indemnitor written notice of such claim or the commencement of such action or
proceeding.  The Indemnitor shall have the right to compromise or to defend any
such matter, at its expense and by its own counsel, except that no such
compromise shall include any agreement requiring the Indemnified Party to take
any action or to refrain from taking any action without the Indemnified Party's
written consent, which shall not unreasonably be withheld or delayed.  If the
Indemnitor shall undertake to defend any such asserted liability, it shall
promptly notify the Indemnified Party of its intention to do so, and the
Indemnified Party agrees to cooperate with the Indemnitor and its counsel in the
defense of any such asserted liability.  In any event, the Indemnified Party
shall have the right to approve any compromise or settlement sought by the
Indemnitor, and the Indemnitor shall have the right to approve any compromise or
settlement sought by the Indemnified Party, which approval, in either case,
shall not be unreasonably withheld.  The Indemnified Party shall have the right
to employ its own counsel in any such action, but the fees and expenses of such
counsel shall be at the expense of such Indemnified Party unless (i) the
Indemnitor shall not in fact have employed counsel reasonably satisfactory to
the Indemnified Party; or (ii) the Indemnified Party shall have reasonably
concluded that such action involves or is likely to involve a customer, supplier
or other party with which the Indemnified Party has or reasonably anticipates
having in the following twelve months, a commercial relationship or that there
may be a conflict of interest between it and the Indemnitor in the conduct of
the defense of such action (in which case the Indemnified Party shall have the
right to direct the defense of the action using counsel reasonably satisfactory
to the Indemnitor).

inure to the benefit of and be enforceable by the heirs, personal
representatives, successors and assigns of the parties hereto, and shall not be

                                       33

 
assignable by the parties, except that Buyer may assign any of its rights or

event that such court shall determine any such provision, or portion thereof
wholly unenforceable, the remaining provisions of this Agreement shall
nevertheless remain in full force and effect provided that the severing of such
provision, or portion thereof will not materially change the substance of this
Agreement.

the execution of, or the transactions contemplated by, this Agreement without

After the Closing, any public statements and press releases shall be made by
Buyer in its sole discretion.

          10.10  Further Assurances.  Subsequent to the Closing, Sellers shall
