     The parties hereby agree as follows:

                                   ARTICLE I

                                   THE OFFER

     1.1  The Offer.
          ---------
 
          (a) Subject to the provisions of this Agreement and provided that
nothing shall have occurred that would result in a failure to satisfy any of the
conditions set forth


 
in Annex I hereto (the "Offer Conditions"), Parent shall cause the Purchaser
   -------                                              
to, as promptly as reasonably practicable after the date hereof, but in no
event later than five (5) business days following the initial public
announcement of the Purchaser's intention to commence the Offer, commence
(within the meaning of Rule 14d-2(a) under the Securities Exchange Act of 1934,
as amended (the "Exchange Act")), the Offer for all of the outstanding Shares
                 ------------                                                
and the associated Series A Participating Cumulative Preferred Stock purchase
rights (collectively, the "Rights") issued pursuant to the Rights Agreement
                           ------                                          
between the Company and First National Bank of Boston, as Rights agent, dated as
of April 24, 1997 (the "Rights Agreement"), at a price of $7.00 per Share (and
                        ----------------                                      
associated Rights), net to the seller in cash.  The obligation of the Purchaser
to accept for payment and to pay for any Shares (and associated Rights) tendered
shall be subject only (i) to such number of Shares, when added to the number of
Shares already owned by Parent, the Purchaser or any direct or indirect wholly
owned subsidiary of Parent, as shall constitute fifty-one percent (51%) of the
Company's Fully Diluted Shares (as defined in Section 4.2) being validly
tendered prior to the expiration or termination of the Offer and not withdrawn
(the "Minimum Share Condition") and (ii) to the other Offer Conditions.  The
      -----------------------                                               
Purchaser may at any time transfer or assign to one or more corporations
directly or indirectly wholly owned by Parent the right to purchase all or any
portion of the Shares (and associated Rights) tendered pursuant to the Offer
(the "Tendered Shares"), but no such assignment shall relieve the Purchaser of
      ---------------                                                         
its obligations hereunder.  The Purchaser expressly reserves the right to waive
any of the Offer Conditions (but not the Minimum Share Condition) and to modify
the terms of the Offer; provided, however, that, without the prior written
                        --------  -------                                 
consent of the Company, the Purchaser shall not amend or modify the terms of the
Offer to (i) reduce the cash price to be paid pursuant to the Offer, (ii) reduce
the number of Shares (and associated Rights) as to which the Offer is made,
(iii) change the form of consideration to be paid in the Offer, or (iv) impose
conditions to the Offer in addition to the Offer Conditions or modify the Offer
Conditions (other than to waive any Offer Condition to the extent permitted by
this Agreement), or (v) make any other change or modification in any of the
terms of the Offer in any manner that is adverse to holders of the Shares.
Subject to the terms and conditions thereof, the Offer shall expire at midnight,
New York City time, on the date that shall be 20 business days after the date on
which the Offer shall be commenced.  The Offer may not be extended without the
Company's prior written consent; provided, however, that the Purchaser may (x)
                                 --------  -------                            
from time to time extend (and re-extend) the Offer, if at the scheduled
expiration date of the Offer any of the Offer Conditions (other than the Minimum
Share Condition) shall not have been satisfied or waived, until such time as
such conditions shall be satisfied or waived; (y) extend the Offer for any
period required by any rule, regulation, interpretation or position of the
Securities and Exchange Commission (the "SEC") or the staff thereof applicable 
                                         ---  
to the Offer; or (z) extend (and re-extend) the Offer for any reason on one or
more occasions for an aggregate period of not more than twenty (20) business
days beyond the latest expiration date that would otherwise be permitted under
clause (x) or (y) above if on such expiration date there shall not have been
tendered at least that number of Shares (and associated Rights) necessary to
permit the Merger to be effected without a meeting of the Company's stockholders
in accordance with the DGCL.

          (b) As soon as reasonably practicable on the date of commencement of
the Offer, the Purchaser shall file with the SEC a Tender Offer Statement on
Schedule 14D-1 (together with all amendments and supplements thereto, the
"Schedule 14D-1") with respect to
---------------                                                               

                                      -2-


 
the Offer.  The Schedule 14D-1 shall contain or shall incorporate by reference
an offer to purchase and a related letter of transmittal and summary
advertisement (such Schedule 14D-1 and Offer to Purchase and the documents
included therein or incorporated therein by reference pursuant to which the
Offer shall be made, together with any supplements or amendments thereto, the
"Offer Documents").  Parent and the Purchaser agree that the Offer Documents 
 ---------------                                                  
shall comply as to form in all material respects with the Exchange Act and the
rules and regulations promulgated thereunder and, on the date filed with the
SEC and on the date first published, sent or given to the Company's
stockholders, shall not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in light of the circumstances under which they
were made, not misleading, except that no representation is made by Parent or
the Purchaser with respect to information supplied by the Company or any of its
representatives which is included in the Offer Documents.  Each of Parent, the
Purchaser and the Company agrees to correct promptly any information provided
by it for use in the Offer Documents if and to the extent that such information
shall have become false or misleading in any material respect, and each of
Parent and the Purchaser further agrees to take all steps necessary to amend or
supplement the Offer Documents and to cause the Offer Documents as so amended or
supplemented to be filed with the SEC and to be disseminated to the Company's
stockholders, in each case as and to the extent required by applicable federal
securities laws.  The Company and its counsel shall be given a reasonable
opportunity to review the Offer Documents and all amendments and supplements
thereto prior to their filing with the SEC or dissemination to stockholders of
the Company.  Parent and the Purchaser agree to provide the Company and its
counsel any comments Parent, the Purchaser or their counsel may receive from the
SEC or its staff with respect to the Offer Documents promptly after the receipt
of such comments.

          (c) Subject to the terms and conditions of the Offer and of this
Agreement, the Purchaser shall, and the Parent shall cause the Purchaser to,
accept for payment and pay for all Shares (and associated Rights) which have
been validly tendered and not withdrawn pursuant to the Offer as promptly as
practicable following expiration of the Offer.

     1.2  Company Action.
          --------------
 
          (a) The Company hereby approves of and consents to the Offer and
represents that at a meeting duly called and held the Board of Directors of the

and adopted this Agreement and the transactions contemplated hereby and
determined that the Offer and the Merger are in the best interests of the
Company and its stockholders and on terms that are fair to such stockholders,
(ii) by unanimous vote of all directors present and voting, amended the Rights
Agreement to make the Rights Agreement inapplicable to the Offer, the Merger,
the Company Stock Option (as defined in Section 5.5), this Agreement, the
Support Agreements, the Director Option Termination Agreements and any other
transaction contemplated hereby and thereby, and determined that such amendment
to the Rights Agreement is in the best interests of the Company and its
stockholders, and (iii) recommended that the Company's stockholders accept the
Offer and tender all of their Shares (and associated Rights) in connection
therewith and, if required under the DGCL, approve this Agreement and the
transactions contemplated hereby (it being

                                      -3-


 
understood that, notwithstanding anything in this Agreement to the contrary, if
the Company's Board of Directors modifies or withdraws its recommendation in
accordance with the terms of Section 5.3(b), such modification or withdrawal
shall not constitute a breach of this Agreement).  The Company represents that
its Board of Directors has received the written opinion of Volpe Brown Whelan & Company LLC (its "Financial Advisor") that the consideration to be received 
                  -----------------  
by the holders (other than Parent and the Purchaser) of Shares (and associated
Rights) pursuant to each of the Offer and the Merger is fair to such holders
from a financial point of view, and that a complete and correct signed copy of
such opinion has been delivered on or prior to the date hereof by the Company
to Parent.  The Company hereby consents to the inclusion in the Offer Documents
of the recommendation of the Company's Board of Directors described in the
immediately preceding sentence (subject to the right of the Board of Directors
to modify or withdraw such recommendation in accordance with Section 5.3(b)). 
The Company represents that it has been authorized by its Financial Advisor to
permit, subject to the prior review by its Financial Advisor, the inclusion of
the fairness opinion (and a description thereof) in the Offer Documents, the
Schedule 14D-9 (as defined in Section 1.2(b)) and the Proxy Statement (as
defined in Section 4.6).

          (b) As soon as reasonably practicable on the date of commencement of
the Offer, the Company shall file with the SEC a Solicitation/Recommendation
Statement on Schedule 14D-9 with respect to the Offer (together with all
amendments and supplements thereto, the "Schedule 14D-9") containing the
                                         --------------                 
recommendation of the Company's Board of Directors described above in Section
1.2(a) (subject to the right of the Board of Directors to modify or withdraw
such recommendation in accordance with Section 5.3(b)) and shall mail the
Schedule 14D-9 to the stockholders of the Company.  The Company agrees that the
Schedule 14D-9 shall comply as to form in all material respects with the
requirements of the Exchange Act and the rules and regulations promulgated
thereunder and, on the date filed with the SEC and on the date first published,
sent or given to the Company's stockholders, shall not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading, except that no
representation is made by the Company with respect to information supplied by
Parent or the Purchaser or any of their respective representatives which is
included in the Schedule 14D-9.  Each of the Company, Parent and the Purchaser
agrees to correct promptly any information provided by it for use in the
Schedule  14D-9 if and to the extent that such information shall have become
false or misleading in any material respect, and the Company further agrees to
take all steps necessary to amend or supplement the Schedule 14D-9 and to cause
the Schedule 14D-9 as so amended or supplemented to be filed with the SEC and
disseminated to the Company's stockholders, in each case as and to the extent
required by applicable federal securities laws.  Parent and its counsel shall be
given a reasonable opportunity to review the Schedule 14D-9 and all amendments
and supplements thereto prior to their filing with the SEC or dissemination to
stockholders of the Company.  The Company agrees to provide Parent and its
counsel with any comments the Company or its counsel may receive from the SEC or
its staff with respect to the Schedule 14D-9 promptly after the receipt of such
comments.
 

                                      -4-


 
          (c) In connection with the Offer, the Company shall, or shall cause
its transfer agent to, furnish the Purchaser promptly with mailing labels
containing the names and addresses of the record holders of Company Common Stock
as of a recent date and of those persons becoming record holders subsequent to
such date, together with copies of all lists of stockholders, security position
listings and computer files and all other information in the Company's
possession or control regarding the beneficial owners of Company Common Stock,
and shall furnish to the Purchaser such information and assistance (including
updated lists of stockholders, security position listings and computer files) as
the Purchaser may reasonably request in communicating the Offer to the Company's
stockholders.  Subject to the requirements of applicable law, and except for
such steps as are necessary to disseminate the Offer Documents and any other
documents necessary to consummate the Offer or the Merger, Parent and the
Purchaser and their agents shall hold in confidence the information contained in
any such labels, listings and files, will use such information only in
connection with the Offer and the other transactions contemplated hereby and, if
this Agreement shall be terminated, will deliver, and will use their reasonable
efforts to cause their agents to deliver, to the Company all copies of such
information then in their possession or control.

          (a) Promptly upon the purchase by the Purchaser of Shares (and
associated Rights) in the Offer, and from time to time thereafter, the Purchaser
shall be entitled to designate that number of directors, rounded up to the next
whole number, on the Company's Board of Directors that equals the product of (i)
the total number of directors on the Company's Board of Directors (giving effect
to the election of any additional directors pursuant to this Section 1.3) and
(ii) the percentage that the number of Shares owned by the Purchaser, Parent and
any direct or indirect wholly owned subsidiary of Parent (including Shares (and
associated Rights) purchased in the Offer) bears to the total number of Shares
(and associated Rights) outstanding at such time, and to effect the foregoing
the Company shall upon request by the Purchaser, at the Company's election,
either increase the number of directors comprising the Company's Board of
Directors or obtain and accept resignations of incumbent directors.  The first
date on which designees of the Purchaser shall constitute a majority of the
Company's Board of Directors is referred to in this Agreement as the "Cut-Off
                                                                      -------
Date." At such time, the Company will cause individuals designated by the
----                                                                     
Purchaser to constitute the same percentage as such individuals represent on the
Company's Board of Directors of  (x) each committee of the Board, (y) if
requested by Purchaser, each board of directors or other governing body of each
Subsidiary of the Company, and (z) if requested by Purchaser, each committee of
each such board or governing body.

          (b) The Company shall promptly take all actions required pursuant to
Section 14(f) and Rule 14f-1 of the Exchange Act in order to fulfill its
obligations under this Section 1.3 and shall include in the Schedule 14D-9 such
information with respect to the Company and its officers and directors as is
required under Section 14(f) and Rule 14f-1 to fulfill such obligations.  The
Purchaser will supply to the Company any information with respect to itself and
its nominees, officers, directors and affiliates required by Section 14(f) and
Rule 14f-1.

                                      -5-


 
          (c) Following the Cut-Off Date and prior to the Effective Time (as
defined below), if the Company shall have at least one director who is neither
an employee of the Company or any of its Subsidiaries nor otherwise affiliated
with the Purchaser (one or more of such directors, the "Independent Directors"),

any amendment of this Agreement or the Certificate of Incorporation or Bylaws of
the Company or any of its Subsidiaries, any termination or amendment of this
Agreement by the Company, any extension by the Company of the time for the
performance of any of the obligations or other acts of Parent or the Purchaser
or any exercise or waiver of any of the Company's rights hereunder, will require
the concurrence of a majority of the Independent Directors.

Shares (and associated Rights) represented thereby in exchange therefor, the
Certificate shall forthwith be canceled.  Until so surrendered and exchanged,
each Certificate shall represent solely the right to receive the Merger Price
for the Shares (and associated Rights) represented thereby, without any interest
thereon.  Upon the surrender and exchange of such an outstanding Certificate,
the holder thereof shall receive the Merger Price multiplied by the number of
Shares (and associated Rights) represented by such Certificate, without any
interest thereon.  If any cash is to be paid to a name other than that in which
the Certificate surrendered in exchange therefor is registered, it shall be a
condition to such payment or exchange that the person requesting such payment or
exchange shall pay to the Exchange Agent any transfer or other taxes required by
reason of the payment of such cash to a name other than that of the registered
holder of the Certificate surrendered, or such person shall establish to the
satisfaction of the Exchange Agent that such tax has been paid or is not
applicable.  Notwithstanding the foregoing, neither the Exchange Agent nor any
party hereto shall be liable to a holder of Certificates for any part of the
Merger Price payments made to a public official pursuant to applicable abandoned
property, escheat or similar laws.

          (b) Promptly following the sixth month after the Effective Time, the
Exchange Agent shall return to the Surviving Corporation all cash relating to
the transactions described in this Agreement, and the Exchange Agent's duties
shall terminate.  Thereafter, each holder of a Certificate may surrender such
Certificate to the Surviving Corporation and (subject to applicable abandoned
property, escheat and similar laws) receive in exchange therefor the Merger
Price for such Shares (and associated Rights), without any interest thereon, but
shall have no greater rights against the Surviving Corporation than may be
accorded to general creditors of the Surviving Corporation under applicable law.
At and after the Effective Time, holders of Certificates shall cease to have any
rights as stockholders of the Company except for the right to surrender such
Certificates in exchange for the Merger Price for such Shares (and associated
Rights) or to perfect their right of appraisal with respect to their Shares (and
associated Rights) pursuant to the applicable provisions of the DGCL and Section
2.4 below, and there shall be no transfers on the stock transfer books of the

associated Rights) in accordance with the DGCL ("Dissenting Shares") shall not

be converted into the right to receive the Merger Price at the Effective Time,
unless and until the holder of such Dissenting Shares shall have failed to
perfect or shall have effectively withdrawn or lost such right to appraisal and
payment under the DGCL.  If a holder of Dissenting Shares (a "Dissenting

-----------                                                            
withdrawn or lost such right to appraisal and payment, then, as of the Effective
Time or the occurrence of such event, whichever last occurs, such Dissenting
Shares shall be converted into and represent solely the right to receive the
Merger Price, without any interest thereon, as provided in Section 2.2.

          (b) The Company shall give Parent (i) prompt notice of any written
demands for appraisal, withdrawals of demands for appraisal and any other
instruments served pursuant to Section 262 of the DGCL and received by the
Company, and (ii) the opportunity to control all negotiations and proceedings
with respect to such demands for appraisal.  The Company shall not, except with

          (a) The business of the Company and its Subsidiaries, as presently
conducted, is not being conducted in default or violation of any term, condition
or provision of (i) their respective charter or bylaws, or (ii) any note, bond,
mortgage, indenture, deed of trust, lease, agreement or other instrument or
obligation of any kind to which the Company or any of

                                      -14-

          -----------------------------------
 
          (a) The Company has filed all required reports, schedules, forms,
statements and other documents with the SEC since January 1, 1995 (the "SEC
                                                                        ---
Documents").  As of their respective dates, the SEC Documents complied in all
---------                                                                    
material respects with the requirements of the Securities Act of 1933, as
amended (the "Securities Act"), or the Exchange Act, as the case may be, and the
              --------------                                                    
rules and regulations of the SEC promulgated thereunder applicable to such SEC
Documents, and, at the time of filing, none of the SEC Documents contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading.  The
financial statements of the Company included in the SEC Documents (the "SEC
                                                                        ---
Financial Statements") comply as to form in all material respects with
--------------------                                                  
applicable accounting requirements and the published rules and regulations of
the SEC with respect thereto, have been prepared in accordance with generally
accepted accounting principles applied on a consistent basis during the periods
involved and fairly present the financial position of the Company as of the
dates thereof and its statements of operations, stockholders' equity and cash
flows for the periods then ended (subject, in the case of unaudited statements,
to normal and recurring year-end audit adjustments which are not material).  The
Company has heretofore delivered to Parent complete and correct copies of all of
the SEC Documents and all amendments and modifications thereto, as well as, to
the extent any shall exist, all amendments and modifications that have not been
filed by the Company with the SEC to all agreements, documents and other
instruments that previously had been filed by the Company with the SEC and are
currently in effect.

          (b) The Company has delivered to Parent an unaudited balance sheet as
at September 30, 1998, and unaudited statements of income as of and for the six
months then ended (the "Interim Financial Statements," and together with the SEC
                        ----------------------------                            
Financial Statements, the "Company Financial Statements").
                           ----------------------------   

          (c) Except as and to the extent set forth on the balance sheet of the
Company as at September 30, 1998, including the notes thereto, the Company has
no liability or

                                      -15-


 
obligation of any nature (whether accrued, absolute, contingent or otherwise)
which would be required to be reflected on a balance sheet, or in the notes
thereto, prepared in accordance with generally accepted accounting principles,
except for liabilities and obligations incurred in the ordinary course of
business consistent with past practice since September 30, 1998 which could not
reasonably be expected to have a Material Adverse Effect.

     4.9  Litigation.
          ----------
 
          (a) There is no suit, action or proceeding pending or, to the
knowledge of the Company, threatened against the Company or any of its
Subsidiaries.  No Governmental Entity has at any time challenged or questioned
in a writing delivered to the Company or any of its Subsidiaries the legal right
of the Company or any of its Subsidiaries to design, manufacture, offer or sell
any of their respective products in the present manner or style thereof.

          (b) Neither the Company nor any of its Subsidiaries has ever been
notified in writing that it has been subject to an audit, compliance review,
investigation or like contract review by the office of the Inspector General of
the U.S. General Services Administration or any other Governmental Entity or
agent thereof in connection with any government contract (a "Government Audit").
                                                             ---------------- 
To the Company's knowledge, no Government Audit is threatened, and in the event
of any such Government Audit, to the knowledge of the Company, no basis exists
for a finding of material noncompliance with any provision of any government
contract or for a refund of any amounts paid or owed to the Company or any of
its Subsidiaries by any Governmental Entity pursuant to such government
contract.  For any item disclosed in the Company Disclosure Schedule pursuant to
this Section 4.9, a true and complete copy of all material correspondence and
documentation with respect thereto has been made available to Parent.

     4.10  Labor Agreements and Actions.
           ----------------------------
 
          (a) Neither the Company nor any of its Subsidiaries is bound by or
subject to (and none of their respective assets or properties are bound by or
subject to) any written or oral, express or implied, contract, commitment or
arrangement with any labor union, and no labor union has requested or, to the
knowledge of the Company, has sought to represent any of the employees,
representatives or agents of the Company or any of its Subsidiaries.  There is
no strike, unfair labor practice complaint or other labor dispute involving the
Company or any of its Subsidiaries pending, or to the knowledge of the Company
threatened, which is reasonably likely to have a Material Adverse Effect, nor is
the Company aware of any labor organization activity involving its or any of its
Subsidiaries' employees.  Neither the Company nor any of its Subsidiaries is
engaged in any unfair labor practice and neither the Company nor any of its
Subsidiaries is in material violation of any applicable laws respecting
employment and employment practices, terms and conditions of employment, and
wages and hours.  Neither the Company nor any of its Subsidiaries has
experienced any material work stoppage or other material labor difficulty.

          (b) The employment of each officer and employee of the Company and
each of its Subsidiaries is terminable at the will of the Company or such
Subsidiaries, as the

                                      -16-


 
case may be, and neither the Company nor any of its Subsidiaries has entered
into any oral or written agreements with any of their respective officers or
employees that provide for severance or termination pay or acceleration of
vesting on stock options or restricted stock.  Neither the Company nor any of
its Subsidiaries is a party to any agreement, contract or arrangement with any
officer or employee the benefits of which are contingent, or the terms of which
are materially altered, upon the occurrence of a transaction involving the
Company or such Subsidiaries, as the case may be, of the nature of any of the
transactions contemplated by this Agreement.

          (c) The Company and each of its Subsidiaries has complied in all
material respects with all applicable state and federal equal employment
opportunity laws and with other laws related to employment.  The Company and
each of its Subsidiaries has conducted all employee terminations and reductions
in force in accordance with company policy and in compliance with all applicable
laws, including but not limited to the Worker Adjustment and Retraining
Notification Act ("WARN"). There is no, and has not been any, claim against the
                   ----                                                        
Company or any of its Subsidiaries, or to the Company's knowledge, threatened
against the Company or any of its Subsidiaries, based on actual or alleged race,
age, sex, disability or other harassment or discrimination, or similar tortious
conduct, nor to the knowledge of the Company, is there any basis for any such
claim.  There are no pending claims against the Company or any of its
Subsidiaries under any workers' compensation plan or policy or for long term
disability.  There are no pending or threatened wage claims against the Company
or any of its Subsidiaries, and there are no other proceedings pending or, to
the knowledge of the Company, threatened against the Company or any of its
Subsidiaries, by any employee or former employee.

          (d) The Company is not aware that any officer of the Company or any of
its Subsidiaries, or any employee whose technical knowledge is of significant
importance for the development of products of the Company or any of its
Subsidiaries (including, but not limited to, the employees listed on Annex I to
the Company Disclosure Schedule), or that any group of officers or such
employees of the Company or any of its Subsidiaries, intends to terminate such
officer's or such employee's employment with the Company or its Subsidiaries, as
the case may be, nor does the Company or any of its Subsidiaries have any
present intention to terminate the employment of any officer or any such
employee.  To the knowledge of the Company, each officer and each such employee
of the Company and its Subsidiaries is currently devoting 100% of his or her
business time attending to the affairs of the Company or its Subsidiaries, as
the case may be.

     4.11  Certain Agreements and Employee Benefit Plans.
           ---------------------------------------------
 
          (a) Schedule 4.11(a) of the Company Disclosure Schedule contains a
true and complete summary or list of, or otherwise describes, (i) all employee
benefit plans (within the meaning of Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA")) which are maintained,
                                          -----                         
contributed to or sponsored by the Company or any trade or business (whether or
not incorporated) which is treated as a single employer with the Company (an
"ERISA Affiliate") within the meaning of Section 414(b), (c), (m) or (o) of the
----------------                                                               
Internal Revenue Code of 1986, as amended (the "Code"), for the benefit of any
                                                ----                          
current or former employee, officer or director of the Company or an ERISA
Affiliate, (ii) each loan to a

                                      -17-


 
non-officer employee and loans to officers and directors of the Company or any
of its Subsidiaries, (iii) all bonus, stock option, stock purchase, restricted
stock, phantom stock, or stock appreciation right plans, programs or
arrangements, (iv) all incentive, deferred compensation, supplemental
retirement, savings, profit sharing, or severance plans, programs or
arrangements, (v) all sabbatical, employee relocation, vacation, cafeteria
benefit (Code Section 125), dependent care benefit (Code Section 129), life or
accident insurance, disability, medical, dental, vision or any other fringe or
benefit plans, programs or arrangements, and (vi) any current or former
employment or executive compensation or severance agreements, written or
otherwise, for the benefit of, or relating to, any present or former employee,
consultant or director of the Company or any of its Subsidiaries, as to which
(with respect to any of items (i) through (vi) above) any obligation or
potential liability is borne by the Company or any of its Subsidiaries
(together, the "Company Employee Plans").
                ----------------------   

          (b) The Company has delivered to Parent a copy of each of the Company
Employee Plans and related plan documents (including trust documents, insurance
policies or contracts, employee booklets, summary plan descriptions and other
authorizing documents, and, to the extent still in its possession, any material
employee communications relating thereto) and has, with respect to each Company
Employee Plan which is subject to ERISA reporting requirements, provided copies
of any Form 5500 reports filed for the last three plan years.  Any Company
Employee Plan intended to be qualified under Section 401(a) of the Code has
either obtained from the Internal Revenue Service a favorable determination
letter as to its qualified status under the Code, including all amendments to
the Code effected by the Tax Reform Act of 1986 and subsequent legislation, or
has applied to the Internal Revenue Service for such a determination letter
prior to the requisite period under applicable Treasury Regulations or Internal
Revenue Service pronouncements in which to apply for a determination letter and
to make any amendments necessary to obtain a favorable determination.  The
Company has also furnished Parent with the most recent Internal Revenue Service
determination letter issued with respect to each such Company Employee Plan, and
nothing has occurred since the issuance of each such letter which could
reasonably be expected to cause the loss of the tax-qualified status of any
Company Employee Plan subject to Code Section 401(a).

          (c) With respect to each Company Employee Plan, (i) there has been no
"prohibited transaction," as such term is defined in Section 406 of ERISA and
Section 4975 of the Code, (ii) each Company Employee Plan has been administered
in accordance with its terms and in compliance with the requirements prescribed
by any and all statutes, rules and regulations (including ERISA and the Code),
(iii) the Company (or, as appropriate, an ERISA Affiliate) has prepared in good
faith and timely filed all requisite governmental reports (which were true and
correct as of the date filed) and has properly and timely filed and distributed
or posted all notices and reports to participants and beneficiaries required to
be filed, distributed or posted, (iv) no suit, administrative proceeding, action
or other litigation has been brought, or to the knowledge of the Company is
threatened against such Company Employee Plan, including any audit or inquiry by
the Internal Revenue Service or United States Department of Labor, (v) the
Company and each ERISA Affiliate have performed all material obligations
required to be performed by them and are not in any material respect in default
under or in violation of, and have no knowledge of any material default or
violation of, such Company Employee Plan, (vi)

                                      -18-


 
neither the Company nor any ERISA Affiliate is subject to any liability or
penalty under Sections 4976 through 4980 of the Code or Title I of ERISA, (vii)
all contributions required to be made by the Company or any ERISA Affiliate
have been made on or before their due dates, (viii) no "reportable event"
within the meaning of Section 4043 of ERISA (excluding any such event for which
the thirty (30) day notice requirement has been waived under the regulations to
Section 4043 of ERISA) nor any event described in Section 4062, 4063 or 4041 of
ERISA has occurred, (ix) such Company Employee Plan is not covered by, and
neither the Company nor any ERISA Affiliate has incurred or expects to incur
any material liability under, Title IV of ERISA or Section 412 of the Code, and
(x) neither the Company nor any ERISA Affiliate is a party to, or has made any
contribution to or otherwise incurred any obligation under, any "multi-employer
plan" as defined in Section 3(37) of ERISA.

          (d) With respect to each Company Employee Plan, the Company has
complied with (i) the applicable health care continuation and notice provisions
of the Consolidated Omnibus Budget Reconciliation Act of 1985 ("COBRA") and the
                                                                -----          
proposed regulations thereunder, (ii) the applicable requirements of the Family
and Medical Leave Act of 1993 ("FMLA") and the regulations thereunder, and (iii)
                                ----                                            
the applicable requirements of the Health Insurance Portability and
Accountability Act of 1996 ("HIPAA") and the temporary regulations thereunder.
                             -----                                            
The Company has no material obligations under COBRA with respect to any former
employees or qualifying beneficiaries thereunder.

          (e) With respect to each Company Employee Plan, there has been no
amendment to, written interpretation or announcement (whether or not written) by
the Company or other ERISA Affiliate relating to, or change in participation or
coverage under, such Company Employee Plan which would materially increase the
expense of maintaining such Plan above the level of expense incurred with
respect to that Plan for the most recent fiscal year included in the Company
Financial Statements.

          (f) Schedule 4.11(f) of the Company Disclosure Schedule contains a
true and correct list of each person who holds any stock option as of the date
hereof, together with (i) the number of shares of Company Common Stock subject
to such stock option, (ii) the date of grant of such stock option, (iii) the
extent to which such stock option is currently vested and, to the extent such
stock option is unvested, the vesting schedule, (iv) the exercise price of such
stock option, (v) whether such stock option is intended to qualify as an
incentive stock option within the meaning of Section 422(b) of the Code (an
"ISO"), and (vi) the expiration date of such stock option.  Schedule 4.11(f) of
 ---                                                                           
the Company Disclosure Schedule also sets forth the aggregate number of ISO's
and nonqualified stock options outstanding as of the date hereof.

          (g) Neither the Company nor any of its Subsidiaries is a party to any
agreement or plan, including, without limitation, any stock option plan, stock
appreciation right plan or stock purchase plan, any of the benefits of which
will be increased, or the vesting of benefits of which will be accelerated, by
the occurrence of any of the transactions contemplated by this Agreement or the
value of any of the benefits of which will be calculated on the basis of any of
the transactions contemplated by this Agreement.

                                      -19-


 
          (h) All options under the Company's 1995 Employee Stock Purchase Plan
shall terminate as of December 15, 1998 and all actions have been taken such
that the termination of the options is in full and complete compliance with the
terms of such plan.

     4.12  Taxes.
           -----
 
          (a) The Company and each of its Subsidiaries (i) has filed when due
(taking into account extensions) with the appropriate federal, state, local,
foreign and other governmental agencies, all tax returns, estimates and reports
required to be filed by it, (ii) either paid when due and payable or established
adequate reserves or otherwise accrued all requisite federal, state, local or
foreign taxes, levies, imposts, duties, licenses and registration fees and
charges of any nature whatsoever, and unemployment and social security taxes and
income tax withholding, including interest and penalties thereon ("Taxes"), and
                                                                   -----       
(iii) has established or will establish in accordance with its normal accounting
practices and procedures accruals and reserves that, in the aggregate, are
adequate for the payment of all Taxes not yet due and payable and attributable
to any period preceding the Effective Time.

          (b) No deficiencies for Taxes have been threatened or claimed by any
taxing authority in respect of any tax returns filed by the Company or any of
its Subsidiaries (or any predecessor corporations).  Neither the Company nor any
of its Subsidiaries (nor any predecessor corporation of any of such entities)
has executed or filed with any taxing authority any agreement or other document
extending, or having the effect of extending, the period of assessment or
collection of any Taxes.  Neither the Company nor any of its Subsidiaries is
currently being audited by any taxing authority nor have any of them received
notice of a proposed audit pertaining to Taxes.  There are no tax liens on any
assets of the Company, any of its Subsidiaries or any affiliate, except for
Taxes not yet due and payable.  The accruals and reserves for taxes reflected in
the balance sheet of the Company as at September 30, 1998 are in all material
respects adequate to cover all Taxes accruable through the date thereof
(including interest and penalties, if any, thereon and Taxes being contested) in
accordance with generally accepted accounting principles.

          (c) Neither the Company nor any of its Subsidiaries is a party to, is
bound by, or has any obligation under any tax sharing or similar agreement.

          (d) Neither the Company nor any of its Subsidiaries is required to
include in income (i) any amount in respect of any adjustment under Section 481
of the Code, (ii) any deferred intercompany transaction, or (iii) any
installment sale gain, where the inclusion in income would result in a Tax
liability materially in excess of the reserves therefor.  Neither the Company
nor any of its Subsidiaries has given a consent under Section 341(f) of the
Code.  Neither the Company nor any of its Subsidiaries is, nor has it been at
any time, a "United States real property holding corporation" within the meaning
of Section 897(c)(2) of the Code.  Neither the Company nor any of its
Subsidiaries owns any property of a character which would give rise to any
documentary, stamp or other transfer tax as a result of the transactions
contemplated by this Agreement.

                                      -20-


 
          (e) Neither the Company nor any of its Subsidiaries is a party to any
agreement, contract or arrangement that may result, separately or in the
aggregate, in the payment of any "excess parachute payment" within the meaning
of Section 280G of the Code, determined without regard to Section 280G(b)(4) of
the Code, or under which any person may receive payments subject to the tax
imposed by Section 4999 of the Code, by reason of the transactions contemplated
by this Agreement.

          (f) All independent contractors and consultants of the Company and
each of its Subsidiaries have been properly classified as independent
contractors for the purposes of federal and applicable state laws and laws
applicable to employee benefits and other applicable law.

     4.13  Absence of Certain Changes or Events.  Since September 30, 1998,
           ------------------------------------
except as contemplated by this Agreement, the Company and each of its
Subsidiaries has conducted its business only in the ordinary course consistent
with past practice, and there has not been (i) any damage, destruction or loss,
whether covered by insurance or not, having or which, insofar as reasonably can
be foreseen, in the future would have a Material Adverse Effect, (ii) any
declaration, setting aside or payment of any dividend (whether in cash, stock
or property) with respect to Company Common Stock, or any redemption, purchase
or other acquisition of any of its securities, (iii) any event or change in the
business, operations, properties, prospects, condition (financial or
otherwise), assets or liabilities (including, without limitation, contingent
liabilities) of the Company or any of its Subsidiaries having, or which,
insofar as reasonably can be foreseen, in the future would have a Material
Adverse Effect, (iv) any labor dispute, other than routine matters, none of
which is material to the Company or any of its Subsidiaries, (v) any entry into
any material commitment or transaction (including, without limitation, any
borrowing or capital expenditure) other than in the ordinary course of business
consistent with past practice, (vi) any material change by the Company in its
accounting methods, principles or practices, (vii) any revaluation by the
Company of any asset (including, without limitation, any writing down of the
value of inventory or writing off of notes or accounts receivable), (viii) any
increase in or establishment of any bonus, insurance, severance, deferred
compensation, pension, retirement, profit sharing, stock option (including,
without limitation, the granting of stock options, stock appreciation rights,
performance awards, or restricted stock awards), stock purchase or other
employee benefit plan, or any other increase in the compensation payable or to
become payable to any officers or key employees of the Company or any of its
Subsidiaries, or (ix) entry by the Company or any of its Subsidiaries into any
licensing or other agreement with regard to the acquisition or disposition of
any material Intellectual Property other than nonexclusive licenses granted in
the ordinary course of business consistent with past practice.

     4.14  Title to Properties; Absence of Liens and Encumbrances; Condition of
           --------------------------------------------------------------------
Equipment.
---------
         
          (a) Neither the Company nor any of its Subsidiaries owns any real
property.

          (b) All of the existing real property leases to which the Company or
any of its Subsidiaries is a party have been previously delivered to Parent.
Schedule 4.14(b) of the Company Disclosure Schedule sets forth a complete and
accurate list of all real property leased by the Company or any of its
Subsidiaries.  All such leases are in full force and effect, are valid and
effective in accordance with their respective terms, and there is not, under any
of such leases, any existing default (by the Company or any of its Subsidiaries
or, to the knowledge of the Company, any other party) or event of default (or
event which with notice or lapse of time, or both, would constitute a default)
that would give rise to a material claim against the Company or any of its
Subsidiaries or, to the knowledge of the Company, any other party.

          (c) The Company and each of its Subsidiaries owns or has valid
leasehold interests in all of its tangible properties and assets (real, personal
and mixed) used in its business, free and clear of any liens (other than liens
for Taxes that are not yet delinquent), charges, pledges, security interests or
other encumbrances, except as reflected in the Company Financial Statements and
except for such imperfections of title and encumbrances, if any, that are not
substantial in character, amount or extent, and that do not and are not
reasonably likely to materially detract from the value, or interfere with the

Subsidiary.  All such permits are valid and in full force and effect.  Each of

Surviving Corporation the obligation to obtain any additional permits for such
activities, absent a change in operations.

          (j) Neither the Company nor any Subsidiary has exposed any persons in
a material manner to, nor received notice of any claim of injury due to exposure
of any person to, hazardous or toxic wastes or substances manufactured, stored,

Subsidiary.

          (k) No hazardous or toxic wastes or substances are present on any
property which has been owned, leased or occupied by the Company or any
Subsidiary, for the conduct of its business which could reasonably be expected
to result in a Material Adverse Effect on the Company and its Subsidiaries taken
as a whole.

          (l) No claim, complaint, or administrative proceeding has been brought
or is currently pending against the Company or any Subsidiary relating to any
liability of the Company or any Subsidiary existing or threatened with respect
to the release of hazardous or toxic wastes or substances or as to the
investigation or remediation of hazardous or toxic wastes or substances.

     5.3  Third Party Acquisitions.
          ------------------------   

          (a) The Company agrees that neither it, nor any of its Subsidiaries,
nor any of the employees, officers or directors of the Company or any of its
Subsidiaries, nor the stockholders who have executed the Support Agreements (the

                                      -35-


 
and the Company shall direct and cause the agents and representatives
(including its Financial Advisor or any other investment banker and any
attorney or accountant retained by it (collectively, "Company Advisors")) of it
                                                      ----------------
and each of its Subsidiaries not to, directly or indirectly, initiate, solicit,
encourage or otherwise facilitate the making of any inquiries in respect of, or
the making of any proposal for, a Third Party Acquisition (as defined in
Section 5.3(b) below).  The Company further agrees that neither it, nor any of
its Subsidiaries, nor any of the employees, officers or directors of the
Company or any of its Subsidiaries, nor the Supporting Stockholders shall, and
the Company shall direct and cause all Company Advisors not to, directly or
indirectly, engage in any negotiations concerning, or provide any information
or data to, or have any discussions with, any Third Party (as defined in
Section 5.3(b) below) relating to the proposal of a Third Party Acquisition, or
otherwise facilitate any effort or attempt to make or implement a Third Party
Acquisition; provided, however, that if at any time prior to the acceptance 
             --------  -------                     
by Purchaser for payment of Shares (and associated Rights) pursuant to the
Offer, the Board of Directors of the Company 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 stockholders under applicable
law, the Company may, in response to an inquiry, proposal or offer for a Third
Party Acquisition which was not solicited subsequent to the date hereof and
that does not result from a breach of this Section 5.3, (x) furnish only such
information with respect to the Company and its Subsidiaries to any such person
pursuant to a customary confidentiality agreement as was delivered to Parent
prior to the execution of this Agreement and (y) participate in the discussions
and negotiations regarding such inquiry, proposal or offer. The Company shall
immediately cease and cause to be terminated any existing activities,
discussions or negotiations with any Third Parties conducted heretofore with
respect to any of the foregoing, and to promptly request each Third Party that
has heretofore executed a confidentiality agreement in connection with its
consideration of acquiring the Company or any of its Subsidiaries, if any, to
return to the Company all confidential information heretofore furnished to such
Third Party by or on behalf of the Company.  The Company shall take the
necessary steps to promptly inform all Company Advisors of the obligations
undertaken in this Section 5.3(a).  The Company agrees to notify Parent
promptly (and in any event within 24 hours) if (i) any inquiries relating to or
proposals for a Third Party Acquisition are received by the Company, any of its
Subsidiaries or any of the Company Advisors, (ii) any information about the
Company or its Subsidiaries is requested from the Company, its Subsidiaries or
any of the Company Advisors, or (iii) any negotiations or discussions in
connection with a possible Third Party Acquisition are sought to be initiated
or continued with the Company or any of the Company Advisors indicating, in
each such case, in connection with such notice, the principal terms and
conditions of any proposals or offers, including the identity of the offering
party, and thereafter shall keep Parent informed in writing, on a reasonably
current basis, on the status and terms of any such proposals or offers and the
status of any such negotiations or discussions.

          (b) Except as permitted by this Section 5.3(b), the Board of Directors
of the Company shall not withdraw its recommendation of the Offer or the Merger
and other transactions contemplated hereby or approve or recommend, or cause the
Company or any of its Subsidiaries to enter into any agreement with respect to,
any Third Party Acquisition.  Notwithstanding the preceding sentence, if the
Board of Directors of the Company determines in its good faith judgment, after
consultation with outside counsel, that it is necessary to do so in

                                      -36-


 
order to comply with its fiduciary duties to the Company's stockholders under
applicable law, the Board of Directors may withdraw or alter its recommendation
of the Offer or the Merger and the other transactions contemplated hereby, or
approve or recommend or cause the Company to enter into an agreement with
respect to a Superior Proposal (as defined below), but in each case only (i)
after providing written notice to Parent (a "Notice of Superior Proposal")
                                             --------------------------- 
advising Parent that the Board of Directors has received a Superior Proposal,
specifying the material terms and conditions of such Superior Proposal and
identifying the person or entity making such Superior Proposal and (ii) if
Parent does not, within five (5) business days (or within two (2) business days
with respect to any amendment to any Superior Proposal which was noticed at
least five (5) business days prior to such amendment) after Parent's receipt of
the Notice of Superior Proposal, make an offer which the Board of Directors of
the Company determines in its good faith judgment (based on the advice of its
Financial Advisor or another financial adviser of nationally recognized
reputation) to be as favorable to the Company's stockholders as such Superior
Proposal; provided, however, that the Company shall not be entitled to enter 
          --------  -------          
into any agreement with respect to a Superior Proposal unless this Agreement is
concurrently terminated by its terms pursuant to Section 8.1(e)(i).

          (c) For purposes of this Agreement, "Third Party Acquisition" means
                                               -----------------------       
the occurrence of any of the following events:  (i) the acquisition of the
Company by merger or otherwise by any person or entity (which includes a
"person" as such term is defined in Section 13(d)(3) of the Exchange Act) other
than Parent, the Purchaser or any affiliate thereof (a "Third Party"); (ii) the
                                                        -----------            
acquisition by a Third Party of 20% or more of the total assets of the Company
(other than the purchase of the Company's products in the ordinary course of
business); (iii) the acquisition by a Third Party of 20% or more of the
outstanding Shares; (iv) the adoption by the Company of a plan of partial or
complete liquidation or the declaration or payment of an extraordinary dividend;
(v) the repurchase by the Company of 20% or more of the outstanding Shares; or
(vi) the acquisition by the Company by merger, purchase of stock or assets,
joint venture or otherwise of a direct or indirect ownership interest or
investment in any business whose annual revenues, net income or assets is equal
to or greater than 20% of the annual revenues, net income or assets of the
Company.  For purposes of this Agreement, a "Superior Proposal" means any bona
                                             -----------------                
fide proposal to acquire directly or indirectly, for consideration consisting of
cash and/or securities, 100% of the Shares then outstanding or all or
substantially all the assets of the Company and otherwise on terms which the
Board of Directors of the Company by a majority vote determines in its good
faith judgment (based on consultation with its Financial Advisor or another
financial adviser of nationally recognized reputation) to be reasonably capable
of being completed (taking into account all legal, financial, regulatory and
other aspects of the proposal and the person or entity making the proposal,
including the availability of financing therefor) and more favorable to the
Company's stockholders than the Offer and the Merger.

          (d) The Company shall not be prohibited from disclosing to its
stockholders a position contemplated by Rules 14d-9 and 14e-2 promulgated under
the Exchange Act to the extent such position is arrived at in compliance with
this Section 5.3.

until the earlier of the termination of this Agreement pursuant to its terms or
the Effective Time, the Company will not approve any acquisition of shares of
Company Common Stock by any person (other than Parent, the Purchaser or their
respective affiliates) which would result in such person becoming an
"interested stockholder" (as such term is defined in Section 203 of the DGCL)
or otherwise become subject to Section 203 of the DGCL, unless such acquisition
is related to a Superior Proposal and the Company has complied with Section 5.3
and, if applicable, Section 8.3.

     5.5  Company Stock Option.
          -------------------- 

     (a) Grant of Company Stock Option.  Subject to Section 8.4, the Company 
         -----------------------------

to purchase, for $7.00 per share in cash, newly issued shares of Company Common
Stock representing 19.9% of the Company's total outstanding Company Common

     (b) Term of Company Stock Option.  Parent may exercise the Company Stock
         ----------------------------                                        
Option, in whole or in part, at any time or from time to time from the day (the
"Exercise Commencement Date") on which either an event described in Section

effect, specifying the number of shares of Company Common Stock to be purchased
and a place and date not earlier than one (1) business day nor later than ten
(10) business days from the date such notice is given for the closing of the
purchase.  If any such closing cannot be consummated on the date specified by
Parent in its notice of election to exercise the Company Stock Option as a
result of any restriction arising under any applicable law or regulation, the
date for such closing shall be on such date within five (5) days following the
cessation of all such restrictions as Parent may specify.

     (d) Payment and Delivery of Company Common Stock.  At any closing in
         --------------------------------------------                    
connection with the Company Stock Option, (i) Parent shall make payment to the
Company of the aggregate purchase price for the shares of Company Common Stock
to be purchased by delivery to the Company of a certified, cashier's or bank
check payable to the order of the Company or, if mutually agreed, by wire
transfer of funds to an account designated by the Company, and (ii) the Company
shall deliver to Parent a certificate or certificates representing the shares of
Company Common Stock so purchased, registered in the name of Parent or its
designee.

                                      -38-


 
     (e) Certain Adjustments.  In the event of any change in the Company's
         -------------------                                              
capital stock by reason of stock dividends, stock splits, mergers,
consolidations, recapitalizations, combinations, conversions, exchanges of
Shares, extraordinary or liquidating dividends, or other changes in the
corporate or capital structure of the Company which would have the effect of
diluting or changing Parent's rights hereunder, the number and kind of capital
stock subject to the Company Stock Option and the purchase price per share (but
not the total purchase price) shall be appropriately and equitably adjusted so
that Parent shall receive upon exercise of the Company Stock Option the number
and class of capital stock or other securities or property that Parent would
have received in respect of the shares of Company Common Stock purchasable upon
exercise of the Company Stock Option if the Company Stock Option had been
exercised immediately prior to such event.

     (f) Exercise Commencement Date.  At any time or from time to time after the

Exercise Commencement Date, Parent may, at its election, upon two (2) days'
notice to the Company, surrender all or a part of the Company Stock Option to
the Company, in which event the Company shall pay to Parent, on the day of each
such surrender and in consideration thereof, against tender by Parent of an
instrument evidencing such surrender, an amount in cash per share of Company
Common Stock (the rights to which are surrendered) equal to the excess of (i)
the greater of (x) the closing price of the Company's Common Stock on The Nasdaq
Stock Market on the date of surrender (or the closing price as reported by any
other applicable securities exchange if not listed on The Nasdaq Stock Market,
or if not actively traded, the fair market value as determined by investment
bankers chosen by the Parent) and (y) the price per Share to be paid in the
Third Party Acquisition or tender offer which created the Exercise Commencement
Date, if any, over (ii) the Merger Price.  If all or a portion of the price per
Share to be paid in such Third Party Acquisition or tender offer consists of
non-cash consideration, then the price per Share referred to in clause (i) above
shall be the cash consideration per Share, if any, plus the fair market value of
the non-cash consideration per Share as set forth in such Third Party
Acquisition or tender offer or, if not so set forth, as determined by investment
bankers chosen by the Parent.  Upon exercise of its right to surrender the
Company Stock Option or any portion thereof and the receipt by Parent of cash
pursuant to this Section 5.5(f), any and all rights of Parent to purchase shares
of Company Common Stock with respect to the portion of the Company Stock Option
surrendered pursuant to this Section 5.5(f) shall be terminated.

     (g) Listing and Reservation of Company Common Stock; Notification of Record
         -----------------------------------------------------------------------
Dates.
----- 

     (i) Promptly after the date hereof, and from time to time thereafter if
necessary, the Company will apply to list all of the Company Common Stock
subject to the Company Stock Option on the Nasdaq National Market and will use
its best efforts to obtain approval of such listing as soon as practicable.

     (ii) The Company has taken all necessary corporate and other action to
authorize, reserve, and permit it to issue, and at all times from the date
hereof until such time as the obligation to deliver Company Common Stock upon
the exercise of the Company Stock Option terminates, will have reserved for
issuance, upon any exercise of the Company

                                      -39-


 
Stock Option, the number of Company Common Stock subject to the Company Stock
Option (less the number of shares of Company Common Stock previously issued
upon any partial exercise of the Company Stock Option or as to which the
Company Stock Option may no longer be exercised).

     (iii)  The Company shall give Parent at least ten (10) days' prior written
notice before setting the record date for determining the holders of record of
Company Common Stock entitled to notice of, or to vote on, any matter, to
receive any dividend or distribution or to participate in any rights offering or
other matter, or to receive any other benefit or right, with respect to Company
Common Stock.

     (h) Registration of the Company Common Stock.
         ---------------------------------------- 

     (i) If Parent requests the Company in writing to register under the
Securities Act any of the shares of Company Common Stock owned by Parent, the
Company will use its best efforts to cause the offering of the shares of Company
Common Stock so specified in such request to be registered a soon as practicable
so as to permit the sale or other distribution by Parent of the shares of
Company Common Stock specified in its request (and to keep such registration in
effect for a period of at least ninety (90) days), and in connection therewith
prepare and file as promptly as reasonably possible (but in no event later than
sixty (60) days from receipt of Parent's request) a registration statement under
the Securities Act to effect such registration on an appropriate form, which
would permit the sale of the shares of Company Common Stock by Parent in the
manner specified by Parent in its request.  The Company shall not be obligated
to make effective more than three (3) registration statements pursuant to the
foregoing sentence.  Upon written notice to Parent, the Company may postpone
effecting a registration pursuant to this Section 5.5 on one occasion during any
period of twelve (12) consecutive months for a reasonable time specified in the
notice but not exceeding ninety (90) days (which period may not be extended or
renewed), if (A) an investment banking firm of recognized national standing
shall advise the Company and Parent in writing that effecting the registration
would materially and adversely affect an offering of securities of the Company
the preparation of which had then been commenced, or (B) the Company is in
possession of material non-public information the disclosure of which during the
period specified in such notice the Company believes, in its reasonable
judgment, would not be in the best interests of the Company.

     (ii) The Company shall notify Parent in writing not less than ten (10) days
prior to filing a registration statement under the Securities Act (other than a
filing on Form S-4 or S-8) with respect to any shares of Company Common Stock of
the Company's intention so to file.  If Parent wishes to have any portion of its
shares of Company Common Stock included in such registration statement, it shall
advise the Company in writing to that effect within two (2) business days
following receipt of such notice, and the Company will thereupon include the
number of shares of Company Common Stock indicated by Parent under such
registration statement.  If such registration involves an underwritten public
offering and the managing underwriter shall advise the Company and Parent that
in its view the number of shares of Company Common Stock requested to be
included in such registration (including any

                                      -40-


 
securities which the Company proposes to be included) exceeds the largest
number of shares which can be sold without having an adverse effect on such
offering, including the price at which such shares can be sold (the "Maximum
                                                                     -------

Company, and second, shares of Company Common Stock requested to be registered
by Parent.

     (iii)  The Company shall pay all fees and expenses in connection with any
registration pursuant to this Section 5.5 other than underwriting discounts and
commissions to brokers or dealers and shall indemnify Parent, its officers,
directors, agents, other controlling persons and any underwriters retained by
Parent in connection with such sale of such shares of Company Common Stock in
the customary way, and agree to customary contribution provisions with such
persons, with respect to claims, damages, losses and liabilities (and any
expenses relating thereto) arising (or to which Parent, its officers, directors,
agents, other controlling persons or underwriters may be subject) in connection
with any such offer or sale under the federal securities laws or otherwise,
except for information furnished in writing by Parent or its underwriters to the
Company.  Parent and its underwriters, respectively, shall indemnify the Company
to the same extent with respect to information furnished in writing to the
Company by Parent and such underwriters.

Effective Time, the Company will timely file all reports required to be filed by
it under the Exchange Act.

     5.7  Indemnification.  Parent agrees that all rights to indemnification 
          ---------------                                     
existing in favor of directors, officers or employees of the Company (the

the Company Disclosure Schedule, with respect to matters occurring through the
Effective Time, shall survive the Merger and shall continue in full force and
effect for a period of not less than six (6) years from the Effective Time.
Effective upon the Effective Time, to the fullest extent permitted by law,
Parent shall be directly bound by, and shall guarantee the Company's and the
Surviving Corporation's performance of, the Company's and the Surviving
Corporation's obligations described in the prior sentence for a period of six
(6) years after the Effective Time.  If Parent, the Surviving Corporation or any
of either of its successors or assigns (i) consolidates with or merges into any
other person and shall not be the continuing or surviving corporation or entity
of such consolidation or merger or (ii) transfers all or substantially all of
its properties and assets to any person, none of which actions are restricted by
this Section 5.7, then and in each such case, proper provision shall be made so
that the successors and assigns of Parent and the Surviving Corporation assume
the obligations set forth in this Section 5.7.

     5.8  Rights Agreement.  The Company shall take all necessary action to
          -----------------                                                
render the Rights Agreement inapplicable to the Offer, the Merger, the Company
Stock Option, this Agreement, the Support Agreements, the Director Option

                                                           ------               
breach of a representation or warranty under this Agreement by such party;

          (d) by Parent if (i) prior to the purchase of Shares (and associated
Rights) pursuant to the Offer, (A) the Board of Directors of the Company or any
committee thereof shall have withdrawn or modified its approval or
recommendation of the Offer, this Agreement, the Merger or any other transaction
contemplated by this Agreement; (B) the Board of Directors of the Company or any
committee thereof shall have recommended to the stockholders of the Company,

Company or any committee thereof shall have resolved to do any of the foregoing;

have withdrawn or modified in a manner adverse to the Purchaser or Parent its
approval or

                                      -47-


 
recommendation of the Offer, this Agreement or the Merger in order to approve
the execution by the Company of a definitive agreement providing for the
transactions contemplated by a Superior Proposal, provided that the Company
                                                  --------                 
shall have complied with the provisions of Section 5.3, including the notice
provisions therein; or (ii) Parent or the Purchaser shall have breached in any
material respect any of their respective representations, warranties, covenants
or other agreements contained in this Agreement which breach cannot be or has

not reasonably likely to affect adversely Parent's or the Purchaser's ability to
complete the Offer or the Merger.

     8.2  Effect of Termination.  If this Agreement is terminated pursuant to 
          ---------------------                                    
Section 8.1, this Agreement shall become void and of no effect with no
liability on the part of any party hereto, except for breach of any provision
of this Agreement, and except that the agreements contained in Sections 5.5,
6.3, 6.10, 8.3 and in Article IX shall survive the termination hereof.

     8.3  Certain Payments.
          ----------------   

          (a) In the event that this Agreement is terminated pursuant to Section
8.1(d)(i) or Section 8.1(e)(i), then, in any such event, the Company shall pay
Parent fifty percent (50%) of the Termination Fee (as defined below) within five
(5) days after the first of such events shall have occurred.  The Company shall
pay Parent the remaining fifty percent (50%) of the Termination Fee within the
earlier of (i) nine (9) months following such event, or (ii) five (5) days after
the consummation of a Third Party Acquisition or similar alternative transaction
with any person other than Parent or any of its affiliates.  For purposes of
this Section 8.3, the "Termination Fee" shall be a dollar amount equal to (A)
                       ---------------                                       
three percent (3%) of the amount obtained by multiplying the total number of
Fully Diluted Shares outstanding plus the total number of Excluded Shares by
$7.00, plus (B) an amount equal to Parent's actual and reasonably documented
       ----                                                                 
out-of-pocket fees and expenses (not to exceed $200,000) incurred by Parent and
the Purchaser in connection with the Offer, the Merger, this Agreement and the
transactions contemplated hereby, which amounts shall be payable in immediately
available funds.

          (b) In the event that this Agreement is terminated pursuant to Section
8.1(c) or 8.1(d)(ii), and the Company shall have announced (and subsequently
consummates) or shall have consummated a Third Party Acquisition with any person
other than Parent or any of its affiliates before or within nine (9) months
after the date of such termination, the Company shall pay Parent the entire
Termination Fee within five (5) days after the consummation of the Third Party
Acquisition.

          (c) In the event that the Company shall fail to pay any amounts owing
pursuant to Section 8.3(a) or 8.3(b) when due, interest shall be paid on such
unpaid amounts, commencing on the date such amounts became due, at a rate of six
percent (6%) per annum.  The Company acknowledges that the agreement contained
in this Section 8.3 is an integral part of the transactions contemplated by this
Agreement, and that, without these agreements, Parent would not enter into this
Agreement; accordingly, if the Company fails promptly to pay any amount due

                                      -48-


 
pursuant to this Section 8.3, and, in order to obtain such payment, Parent
commences a suit which results in a judgment against the Company for the amounts
set forth in this Section 8.3, the Company shall pay to Parent its reasonable
costs and expenses (including attorneys' fees and expenses) in connection with
such suit, together with interest on the amounts set forth in this Section 8.3.

          (d)  The Termination Fee shall not be deemed to be liquidated damages,
and the right to the payment of the Termination Fee shall be in addition to (and
not a maximum payment in respect of) any other damages or remedies at law or in
equity to which Parent or the Purchaser may be entitled as a result of the
breach of any term or provision of this Agreement or any Support Agreement.

     8.4  Limitation on Total Profits.  Notwithstanding any provision of this
          ---------------------------                                        
Agreement to the contrary, the Total Profit (as hereinafter defined) that Parent
shall be permitted to realize in respect of the Termination Fee and the Company
Stock Option shall not exceed four percent (4%) of the aggregate purchase price
that would have been payable for one hundred percent (100%) of the Company's
Fully Diluted Shares and one hundred percent (100%) of the Excluded Shares at
$7.00 per share.  In the event Parent's Total Profit would exceed such amount,
Parent shall, at its sole election, (a) reduce the number of Shares subject to
the Company Stock Option, (b) deliver Shares received upon an exercise of the
Company Stock Option to the Company for cancellation, (c) pay an amount of cash
to the Company, or (d) do any combination of the foregoing so that Parent's
actual realized Total Profit shall not exceed four percent (4%) of the aggregate
purchase price that would have been payable for one hundred percent (100%) of
the Company's Fully Diluted Shares and one hundred percent (100%) of the
Excluded Shares at $7.00 per share.  "Total Profit" shall mean the aggregate
                                      ------------                          
(before taxes) of (i) any amount received pursuant to the Company's repurchase
of the Company Stock Option (or any portion thereof), (ii) any amount received
pursuant to the Company's repurchase of the Shares (less the purchase price for
such Shares) subject to the Company Stock Option, (iii) any net cash received
pursuant to the sale of Shares received by Parent in any exercise of the Company
Stock Option to any third party (less the purchase price of such Shares), (iv)
any amounts received on transfer of the Company Stock Option or any portion
thereof to a third party, (v) any equivalent amounts received with respect to
the Option adjusted pursuant to Section 5.5(e), and (vi) the Termination Fee.

any circumstance, is illegal, invalid or unenforceable, (a) a suitable and
