     objected in writing to such statement, the same shall become final and

     agency for collection or which Seller in good faith has reason to believe
     will not be collectible when due, it being understood and agreed that such

     following the delivery of such written schedule by the Seller, the
     Purchaser shall not have objected in writing to such schedule, the same
     shall become final and binding on the parties. If within such 15 day period
     Purchaser objects to such schedule and the parties are unable to agree in

     submit such dispute for resolution as described in Section 11.11. The
     balance of the Accounts Receivable for purposes of determining Net Asset
     value shall be the amount as finally determined pursuant to this paragraph
     (ii). Purchaser hereby agrees to forward promptly to Seller any amounts
     received by it following the Closing in respect of any Accounts Receivable
     which are transferred to Seller pursuant to the terms hereof, and Seller
     hereby agrees to promptly forward to Purchaser any amounts received by it

     same shall become final and binding on the parties. If within such 15-

     agree in good faith as to any portion of such schedule, then the
     parties shall submit such dispute for resolution as described in

     determining Net Asset Value shall be the amount as finally
     determined pursuant to this paragraph (iii).

     book value, if any, determined in accordance with generally 
     accepted accounting principles, of all deferred charges of 
     Sub, as of the close of business on the Closing Date. If within
     15 days following the delivery of such written schedule by
     Seller, the Purchaser shall not have objected in writing to such
     schedule, the same shall become final and binding on the parties.
     If within such 15-day period Purchaser objects to such schedule
     and the parties are unable to agree in good faith as to any
     portion of such schedule, then the parties shall submit such
     dispute for resolution as described in Section 11.11. The book
     value of all deferred charges of Sub for purposes of determining
     Net Asset Value shall be the amount as finally determined
     pursuant to this paragraph (iv).

               (v)    SUB LIABILITIES.  At the Closing, Seller shall 
                      ---------------
     deliver to Purchaser a written schedule setting forth the book
     value, if any, determined in accordance with generally accepted
     accounting principles, of all liabilities of Sub as of the close
     of business on the Closing Date. If within 15 days following the
     delivery of such written schedule by Seller, the Purchaser shall
     not have objected in writing to such schedule, the same shall
     become final and binding on the parties. If within such 15-day
     period Purchaser objects to such schedule and the parties are
     unable to agree in good faith as to any portion of such schedule,
     then the parties shall submit such dispute for resolution as
     described in Section 11.11. The book value of all liabilities of
     Sub for purposes of determining Net Asset Value shall be the
     amount as finally determined pursuant to this paragraph (v).

          (d)  If the Net Asset Value exceeds the Reference Amount, a portion of
the Accounts Receivable, Sub Cash and Inventory, in that order, up to the total
balance thereof on the Closing Date, equal in dollar amount to the amount of
such excess (the "Net Asset Value Surplus") shall be transferred to Seller. If
the Net Asset Value Surplus exceeds the aggregate balance of Accounts
Receivable, Sub Cash and Inventory on the Closing Date, no adjustment shall be
made to the Purchase Price and no further adjustment to, or conveyance of,
assets comprising a portion of the Transferred Assets or Sub's assets shall be
made. Notwithstanding the provisions set forth in Section 5.1, prior to Closing
Seller may, after notifying and obtaining the consent of Purchaser (which
consent shall not be unreasonably withheld or delayed), dispose of, or cause Sub
to distribute to Seller or otherwise dispose of, Accounts Receivable, Sub Cash
or Inventory, or to repay or otherwise remove Sub liabilities, in such amount as
is necessary to assure that the Net Asset Value will not exceed the Reference
Amount.

hereunder other than Permitted Liens, including without limitation, any 
applicable loan prepayment penalties and release fees.

          (c)       Any of the following types of costs and expenses shall be 
prorated as of the Closing Date as follows:

                    (i)   "Cost and Expenses" shall mean all costs and expenses
     related to any (1) Contracts, (2) Permits, (3) insurance premiums for
     policies being assumed by Purchaser hereunder, if any, or (4) utility or
     similar regular periodic charges respecting the Transferred Assets or the
     Business for which a final billing has not been received by Seller, where
     such costs and expenses cover a period of time both prior and subsequent to
     the Closing. Any payments made in respect of the Costs and Expenses shall
     be prorated between Seller and Purchaser on the basis of the actual number
     of days elapsed from the first days of such period to the Closing Date. On
     or before the date which is thirty (30) days after the Closing Date, the
     parties hereto shall determine the amount of all of the Costs and Expenses.
     If Purchaser pays any of the Costs and Expenses for which Seller is
     responsible, Seller shall, within five (5) days of the date of such
     determination, reimburse Purchaser the amount of such Costs and Expenses.
     If Seller pays any of the Costs and Expenses for which Purchaser is
     responsible, Purchaser shall, within five (5) days of the date of such
     determination, reimburse Seller the amount of such Costs and Expenses.

                    (ii)  All property Taxes and special assessments payable but
     not yet due with respect to any of the Transferred Assets shall be prorated
     between Seller and Purchaser on the basis of actual days elapsed between
     the commencement of the current fiscal Tax year and the Closing Date, based
     on a 365-day year, provided, however, that all such assessments which
     Seller has agreed to pay on an installment basis shall be paid in full at
     or prior to the Closing date. In connection with such proration of Taxes
     and assessments, in the event that actual Tax or assessment figures for the
     year of Closing are not available at the Closing Date, an estimated,
     provisional proration of Taxes and assessments shall be made using Tax and
     assessment figures from the preceding year and the Purchase Price shall be
     reduced by Seller's prorated amount of such Taxes and assessments. When
     actual Tax and

                                      12
               
<PAGE>
 
     assessment figures for the year of Closing become available, a
     corrected and definitive proration of Taxes and assessments shall be
     promptly made by Purchaser. In the event that Taxes and assessments
     for the year of Closing exceed the amount estimated in such
     provisional proration, Seller shall pay Purchaser its pro rata share
     of the amount by which the actual Taxes and assessments exceeded the
     estimated Taxes and assessments within five (5) days following
     delivery to Seller of the definitive proration. Similarly, in the
     event that Taxes and assessments for the year of Closing are less than
     the amount estimated in such provisional proration, Purchaser shall
     pay Seller its pro rata share of the amount by which the estimated
     Taxes and assessments exceeded the actual Taxes and assessments within
     five (5) days following determination of the definitive proration.

     Section 2.6    Consents to Assignment of Contracts.  Schedule 2.6 hereto 
                    -----------------------------------   ------------
lists each Contract which, by its terms or by law, may not be assigned without 
the consent of any other party or parties or as to which all rights or remedies 
available to Seller thereunder would not by law pass to Purchaser upon the 
consummation of the transactions provided for in this Agreement (a 
"Nonassignable Contract"). Nothing in this Agreement shall be construed as an 
attempt by Seller to assign to Purchaser pursuant to this Agreement any 
Nonassignable Contract unless such consent or approval shall have been given, 
and from the date hereof through the Closing Date, Seller shall use its 
commercially reasonable efforts to obtain all of such consents and approvals. If
any such consent or approval in respect of, or a novation of, a Nonassignable 
Contract shall not have been obtained on or before the Closing Date and the 
Closing occurs, to the extent lawful, practicable and reasonable in the 
circumstances, Seller, at the request and under the direction of Purchaser, 
shall use its commercially reasonable efforts, including the obtaining of any 
such necessary consent or approval after the Closing, to assure that the 
rights under such Nonassignable Contracts shall be preserved for the benefit of 
Purchaser. Purchaser shall indemnify and hold harmless Seller for any loss, 
cost, claim, damage, liability or expense which Seller may suffer or incur in 
performing its obligations set forth in the preceding sentence.

          (b)  Except as disclosed in Schedule 3.2(b), neither the execution and
                                      ---------------

Company Reports, there are no outstanding or authorized stock appreciation,

     Section 4.8    Fairness Opinion. The Purchaser has received a written 
                    ----------------
opinion from its financial adviser to the effect that, as of the date hereof, 
the terms of the transactions set forth in the Transaction Documents are fair, 
from a financial point of view, to the shareholders of the Purchaser.

     Section 4.9    SEC Reports; Financial Statements. The Purchaser has made 
                    ---------------------------------
available to the Seller true and complete copies of (a) each registration

ended March 31, 1996, each in the form (including exhibits and amendments) filed
with the SEC (collectively, the "Company Reports"). Each Company Report was 
prepared and filed in accordance with all applicable rules and regulations of 
the SEC and at the time of its filing was otherwise in compliance with such 
rules and regulations in all material respects. As of their respective dates, 
the Company Reports did not contain any untrue statement of a material fact or 
omit to state a material fact required to be stated therein or necessary in 
order to made a statement made therein not misleading, except as the same was 
corrected or superseded in a subsequent report or statement filed with the SEC, 
which subsequent report or statement has been delivered to Seller. Except as may
be stated therein, the financial statements (including the notes thereto) 
included in the Company Reports of the Purchaser (i) were prepared in accordance
with the books and records and accounting methods of Purchaser, (ii) present 
fairly in all material respects the financial position and results of operation 
and cash flows of Purchaser as of the dates and for the periods indicated, and 
(iii) were prepared in accordance with generally accepted accounting principals 
consistently applied throughout the periods involved.

     Section 5.2    Due Diligence.
                    -------------

          (a)  From the date hereof through the Closing Date, or such earlier 
date as this Agreement is terminated in accordance with its terms, Seller will, 
and Seller will cause Sub to, make available for inspection to Purchaser and 
Purchaser's authorized representatives, legal counsel, accountants and financing
sources all information reasonably requested by Purchaser relating to Sub, the 
Business, the Transferred Assets, the Licensed Rights and the Assumed 
Liabilities, and shall allow Purchaser and such representatives, legal counsel, 
accountants and financing sources reasonable access to all books, records, 
files, documents, assets, employees, agents, representatives, and contracts of 
Sub and Seller related to Sub, the Business, the Transferred Assets, the 
Licensed Rights or the Assumed Liabilities, including, without limitation, all 
contracts, agreements, leases, insurance policies, stock transfer books, minute 
books, ledgers and books of account, financial statements and reports, working 
papers, Tax and operating records and correspondence files, to the extent 
related to Sub, the Business, the Transferred Assets, the Licensed Rights or the
Assumed

                                      30

Liabilities. The parties hereto acknowledge that Purchaser has not had the 
opportunity to fully perform its due diligence of Seller, Sub, the Business, the
Transferred Assets, the Licensed Rights or the Assumed Liabilities prior to the 
date of this Agreement, and that the due diligence contemplated in this Section 
5.2(a) is intended to give Purchaser the opportunity to conduct additional due 
diligence and elect, if it chooses, to terminate this Agreement. Accordingly, 
Purchaser may terminate this Agreement at any time prior to the date which is 
forty-five (45) days after the date of this Agreement by notifying Seller in 
writing of its election to terminate this Agreement in accordance with this 
Section 5.2(a) if Purchaser determines in its reasonable judgment that the 
financial position, results of operations, business or prospects of Sub, the 
Business or the Transferred Assets differ materially and adversely from 
Purchaser's understanding of such matters at the time of execution of this 
Agreement. Purchaser's right to terminate this Agreement in accordance with this
Section 5.2(a) shall not be limited or affected in any way by the delivery by 
Seller of any revised Schedule or Appendices to this Agreement delivered 
pursuant to Section 11.13 or otherwise. Purchaser shall have the right to make 
copies of any portion of the records referred to in this Section 5.2(a) relating
to Sub, the Business, the Transferred Assets or the Assumed Liabilities, subject
to Section 5.11.

          (b)  From the date hereof through the Closing Date, or such earlier 
date as this Agreement is terminated in accordance with its terms, Purchaser 
will make available for inspection to Seller and Seller's authorized 
representatives, legal counsel and accountants all information reasonably 
requested by Seller relating to Purchaser, Purchaser's financial condition, 
results of operations, business, properties and management and will afford 
Seller the opportunity to ask such questions of representatives of the Purchaser
as Purchaser shall reasonably request. Such information shall be inspected 
during normal business hours and at mutually agreeable locations in a manner 
that does not disrupt the normal business operations of Purchaser.

          (c)  No investigation by Purchaser or Seller shall affect the 
representations or warranties of Purchaser or Seller or the conditions or 
obligations of the parties hereto.

          (d)  If, in the course of its due diligence investigation of Seller 
and Sub or otherwise, Purchaser becomes aware of information which leads it to 
believe that any representation or warranty made by Seller in this Agreement is 
materially inaccurate, or that any covenant contained in Section 5.1 has been 
breached in any material respect, Purchaser will promptly inform Seller of such 
information, at which time Purchaser shall have the right to terminate this 
Agreement in accordance with Section 11.2(a)(v). If Purchaser fails to inform 
Seller of such breach, or notifies Seller of such breach but does not terminate 
this Agreement as permitted by Section 11.2(a)(v), Purchaser shall be deemed to 
automatically waive its rights, if any, to indemnification by Seller for such 
breach pursuant to Article X.

     Section 5.3    No Solicitations.
                    ----------------

          (a)  From the date hereof through the Closing Date, or such earlier 
date as this Agreement is terminated in accordance with its terms, Seller shall 
not, and Seller shall cause Sub and each of Seller's and Sub's respective 
subsidiaries, Affiliates, officers, employees, directors,

                                      31
<PAGE>
 
shareholders and representatives not to, solicit offers, inquires or proposals 
from, or negotiate or participate in discussions with, or disclose information 
to, others in connection with the possible sale or other disposition of (i) all 
or substantially all of the Business, Transferred Assets or the Licensed Rights 
or (ii) any equity interest in Sub.

          (b)  From the date hereof through the Closing Date, or such earlier 
date as this agreement is terminated in accordance with its terms, Purchaser 
shall not, and shall cause its subsidiaries, Affiliates, officers, employees, 
directors, shareholders, and representatives not to, solicit offers, inquiries 
or proposals from other in connection with the possible acquisition by Purchaser
of any business (or equity interest in any Person who operates a business) which
is substantially similar to the Business.

     Section 5.4    Commercially Reasonable Efforts. Upon the terms and subject 
                    -------------------------------
to the conditions hereof, each of Seller and Purchaser agrees to use its 
commercially reasonable efforts (a) to take or cause to be taken all actions to 
be taken by such party and to do or cause to be done all things to be done by 
such party which are necessary, proper, or advisable to meet the conditions to 
Closing set forth in Articles VII and VIII hereof, and (b) to obtain all 
waivers, consents and approvals needed to be obtained by such party; provided, 
however, that notwithstanding any other provision set forth in this Agreement, 
any approval of this Agreement and the transactions contemplated hereby by the 
Board of Directors of either Purchaser or Seller, and any recommendation, if 
any, made by either of such Boards of Directors to their respective stockholders
to approve this Agreement and the transactions contemplated hereby, shall remain
subject to the fiduciary duties of the members of such Boards of Directors to
their respective stockholders under applicable law.

     Section 5.5    Proxy Statement. As soon as practicable after the date 
                    ---------------
hereof, the Purchaser shall take commercially reasonable steps to promptly 
prepare, file with the SEC and mail the Proxy Statement to Purchaser's 
shareholders. The Purchaser represents and warrants, as to all information 
contained in the Proxy Statement which is not supplied by the Seller for 
inclusion therein, that such information, at the date the Proxy Statement is 
mailed to the shareholders of Purchaser and at the time of the Shareholder 
Meeting, will not be false or misleading with respect to any material fact 
contained therein, or omit to state a material fact required to be stated 
therein or necessary to make the statements therein not misleading. The Seller 
represents and warrants, as to all information contained in the Proxy Statement 
which is expressly supplied by Seller for inclusion therein, that such 
information, at the date the Proxy Statement is mailed to the shareholders of 
Purchaser and at the time of the Shareholder Meeting, will not be false or 
misleading with respect to any material fact contained therein, or omit to state
a material fact required to be stated therein or necessary to make the 
statements therein not misleading. The Seller will have no obligation to supply 
any information expressly for inclusion in the Proxy Statement other than the
Financial Statements, and the Seller may require that the Proxy Statement
include reasonable disclaimers as to Seller's liability.

     Section 5.6    Damage or Destruction of Property. If any "Material Assets" 
                    ---------------------------------
shall be substantially damaged or destroyed by fire or other cause on or prior 
to the Closing Date, Seller shall, and Seller shall cause Sub to, promptly 
notify Purchaser and furnish to Purchaser a written 

                                      32
<PAGE>
 
statement of the amount of insurance, if any, that Seller believes will be
payable on account thereof. Purchaser shall then have the right, within ten (10)
days after receipt of such notice from Seller, to: (a) require that Seller
restore, or cause to be restored, prior to Closing the damaged or destroyed
Material Assets to their condition on the date of this Agreement to the extent
such damaged or destroyed Material Assets can be restored; or (b) notify Seller
of Purchaser's intent to close the transactions contemplated in this Agreement
(provided all other conditions to Closing are satisfied) at the time at which
Closing would otherwise occur under the terms of this Agreement, and the
Purchase Price shall be reduced by an amount equal to the excess of (i) the
value of the loss as determined by a third party mutually selected by Purchaser
and Seller, over (ii) the applicable insurance proceeds, if any, conveyed to
Purchaser as contemplated in Appendix I. For purposes of this Section 5.6,
                             ---------- 
"Material Assets" shall be deemed to be such of Sub's assets or the Transferred
Assets for which the cost of replacement, repair or restoration exceeds $250,000
in the aggregate, and which cannot be replaced, repaired or restored by Seller
or Sub within thirty (30) days after the date such Material Assets are damaged
or destroyed. In the event of a loss of Sub's assets or Transferred Assets that
are not "Material Assets," Purchaser and Seller agree to close the transactions
contemplated in this Agreement (provided all other conditions to Closing are
satisfied) and the Purchase Price shall be reduced by an amount equal to the
excess of (1) the value of the loss as determined by a third party mutually
selected by Purchaser and Seller, over (ii) the applicable insurance proceeds,
if any, conveyed to Purchaser as contemplated in Appendix I.

     Section 5.7    Employees, Benefits, Etc.
                    ------------------------  

               (a)  Employees. From the date hereof through and including the
                    ---------  
Closing Date, Seller shall, and Seller shall cause Sub to, permit Purchaser (i)
to met with the employees of Seller who are principally employed in the Business
and with the employees of Sub ("Employees") at such times as shall be approved
by a representative of Seller (which approval shall not be unreasonably
withheld) and (ii) to distribute to such Employees such correspondence, forms
and other documents setting forth the terms and conditions upon which employment
after Closing, if any, by Purchaser or Sub is offered and any other
correspondence, forms and documents relating to employment after the Closing
Date by Purchaser or Sub as Purchaser may request. No later than forty-five (45)
days after the date of this Agreement, Purchaser shall deliver to Seller a list
of up to ten (10) Employees who Purchaser shall in good faith determine to be
essential to the conduct of the Business by Purchaser (the "Key Employee List").
It is explicitly understood and agreed that Purchaser shall have no obligation
under this Agreement to employ or otherwise retain the services of any Employee
of Seller or Sub subsequent to Closing, but many do so at Purchaser's sole
discretion and upon such terms and conditions as shall be acceptable to
Purchaser in Purchaser's sole discretion

               (b)  Benefits. Seller agrees that, with respect to all claims by 
                    --------
Employees of Seller arising from claims incurred on or prior to the Closing Date
under all Benefit Plans, whether insured or otherwise (including, but not 
limited to, bonus, retirement, vacation, life insurance, medical, severance and 
disability programs), Seller at its own expense shall honor or cause to be 
honored such claims, whether made before or after the Closing Date, in 
accordance with the terms and conditions of such Benefit Plans. Except as set 
forth on Schedule 5.7(b), Purchaser shall not be obligated to pay, assume, 
         ---------------
perform or discharge any claim, demand, liability or obligation of any kind 
whatsoever

                                      33
<PAGE>
 
under any Benefit Plan, and Seller shall indemnify and hold harmless Purchaser 
for any loss, cost, claim, damage, liability or expense which Purchaser may 
suffer or incur as a result thereof.

     Section 5.8    Seller's Access to Information. After the Closing, Purchaser
                    ------------------------------
shall allow Seller and its respective authorized representatives full and 
complete access at all reasonable times, and upon reasonable notice, to inspect 
and copy all books, records, contracts, materials and documents transferred to 
Purchaser under this Agreement to the extent reasonably requested by Seller for 
its accounting, Tax and legal purposes. Purchaser shall preserve and maintain 
all such books, records, contracts, materials, and documents for a period of not
less than five (5) years following the Closing Date.

     Section 5.9    Public Announcements. Purchaser and Seller will, and Seller 
                    --------------------
will cause Sub to, consult with each other before issuing any press release or 
otherwise making any public statements with respect to this Agreement or the 
transactions contemplated by this Agreement and will not issue any such press 
release or make any such public statement before such consultation, except as 
may be required by law or any listing agreement with a national securities 
exchange.

     Section 5.10   No Hire. Except as may be otherwise agreed to in writing 
                    -------
between Seller and Purchaser, until the second anniversary of the Closing Date, 
Seller will not employ any Employee who at Closing remains an Employee of Sub or
becomes an employee of Purchaser, unless (a) such individual leaves Sub's or 
Purchaser's employment or gives notice of termination of employment without any 
prior solicitation by Seller, or is given notice of termination of employment by
Sub or Purchaser, or (b) Purchaser ceases to engage in the Business or becomes 
bankrupt.

     Section 5.11   Confidentiality. (a) None of the parties to this Agreement
                    ---------------  
shall, nor shall they permit their respective subsidiaries, Affiliates,
officers, employees, directors, shareholders or representatives to, disclose to
any third party (other than such parties' respective legal counsel, accountants
and other advisors, all of whom shall be required to observe the provisions of
this Section 5.11) any information received from the other party in the course
of investigating, negotiating, and performing the transactions contemplated by
this Agreement; provided, however, that this provision shall not be applicable
                --------  -------
to information which; (i) becomes generally available to the public other than
as a result of a disclosure by the party receiving such information (a
"Receiving Party") or such Receiving Party's Affiliates, officers, directors,
employees, shareholders or representatives, (ii) was available to the Receiving
Party on a non-confidential basis prior to its disclosure to the Receiving Party
by the other party to this Agreement (a "Disclosing Party") or its Affiliates,
officers, directors, employees, shareholders or representatives, (iii) becomes
available to the Receiving Party on a non-confidential basis from a source other
than the Disclosing Party or its Affiliates, officers, directors, employees,
shareholders or representatives when such source is entitled, to the best of the
Receiving Party's knowledge, to make the disclosure, or (iv) was independently
developed by the Receiving Party without reference to the information received
from the Disclosing Party. If either party or any of their respective
Affiliates, officers, directors, employees, shareholders or representatives is
requested or required to disclose any information received by it or to disclose
any such information which is required to be kept confidential by this Section
5.11(a), such party agrees to provide the Disclosing Party with prompt notice of
each such

                                      34







<PAGE>
 
request, to the extent practicable, so that the Disclosing Party may seek an
appropriate protective order or waive compliance by the Receiving Party with the
provisions of this Section 5.11(a) or both. If, absent the entry of a protective
order or the receipt of a waiver under this Agreement, the Receiving Party, its
Affiliates, officers, directors, employees, shareholders or representatives are,
in the opinion of its counsel, legally compelled to disclose such information,
the Receiving Party may disclose such information to the persons and to the
extent required without liability under this Agreement, and such party agrees to
exercise its reasonable commercial efforts to obtain reasonable assurances that
confidential treatment will be accorded any such information so furnished.
Notwithstanding any other provision set forth in this Section 5.11 or elsewhere
in this Agreement, Seller understands and acknowledges that Purchaser will
disclose to its shareholders all information which Purchaser is required by
applicable law to disclose to its shareholders in connection with obtaining the
Shareholder Approval, including but not limited to the terms of the transactions
contemplated in this Agreement and information relating to Sub, the Business and
the Transferred Assets, and Seller hereby consents to such disclosure; provided,
that, (i) Purchaser shall consult with Seller prior to disclosing any
information in reliance on this sentence and, if Seller disputes the need for
such disclosure, the parties will work together in good faith to reach agreement
as to the extent of such information to be disclosed; and (ii) under no
circumstances will Purchaser reveal any Trade Secrets at any time prior to
Closing.

               (b)  Seller and Sub have taken, and after the date hereof Seller
will, and Seller will cause Sub to, take all steps reasonably necessary to
safeguard and maintain the secrecy and confidentiality of any of the Transferred
Assets that constitute Trade Secrets or other confidential or proprietary
information of Seller or Sub. From and after the date hereof, Seller shall not,
and Seller shall cause Sub to not, disclose to any Person (other than Purchaser
and such authorized representatives of Purchaser as Purchaser shall identify to
Seller in writing) any Trade Secrets or other confidential or proprietary
information with respect to the Business or the Transferred Assets except (i) as
otherwise required by law, or (ii) prior to the Closing Date, in the ordinary
course and consistent with the past business practices of Seller and Sub.

               (c)  If this Agreement is terminated pursuant to Section 11.2(a),
prior to December 31, 1998 neither Seller nor Purchaser shall hire (as an
employee or consultant or in any other capacity) any employee or consultant of
the other party hereto without the other party's prior written consent.

               (d)  To the extent that the terms of this Section 5.11 conflict
with the terms of the confidentiality Agreement made December 19, 1995 between
Seller and Purchaser, as amended, the terms of this Section 5.11 shall apply.

     Section 5.12   Financial Statements. As soon as practicable after the date
                    -------------------- 
of this Agreement, but in no event later than sixty (60) days after the date of
this Agreement, Seller shall deliver to Purchaser true, complete and correct
copies of the Financial Statements. Seller hereby acknowledges and agrees that
(a) Purchaser will include the Financial Statements, and certain summary
information therefrom, in the Proxy Statement; (b) Seller has informed the
independent accountants who will prepare the Financial Statements that Purchaser
will include the Financial Statements in the Proxy

                                      35
<PAGE>
 
Statement; and (c) Seller will obtain any consents, whether from the 
independent accountants or otherwise, necessary to include the Financial 
Statements in the Proxy Statement. If the SEC notifies Purchaser that the 
financial statements initially delivered by Seller to Purchaser under this 
Section 5.12 do not meet the requirements of the Securities Act governing the 
form and content of Financial Statements to be included in the Proxy Statement, 
as soon as practicable thereafter Seller shall use commercially reasonable 
efforts to deliver to Purchaser true, complete and correct copies of Financial 
Statements which meet such requirements, and from time to time thereafter, as 
soon as practicable after receipt of comments from the SEC on the Proxy 
Statement, Seller shall continue to revise and update such Financial Statements 
in response to such comments until the SEC provides no objection to the 
inclusion of such Financial Statements in the Proxy Statement. However, if 
Seller reasonably determines that it is unable to provide Financial Statements 
that are satisfactory to the SEC using its commercially reasonable efforts, then
it may so notify Purchaser, whereupon either of Seller or Purchaser may, upon 
delivery of fifteen (15) days prior written notice, terminate this Agreement.

     Section 5.13   Repurchase of Unpaid Accounts Receivable.  If any Account

     Section 5.17   Ownership of Securities.
                    -----------------------

          (a)  Transfer Restrictions. If Seller should decide to dispose of any 
               ---------------------
of the Securities, Seller may do so only pursuant to an effective registration 
statement under the Securities Act or pursuant to an exemption from registration
under the Securities Act. In connection with any offer, resale, pledge or other 
transfer (individually and collectively, a "Transfer") of any Securities, other 
than pursuant to an effective registration statement, Purchaser may require that
the transferor of such Securities provide to the Purchaser an opinion of
counsel, wich opinion shall be reasonably satisfactory in form and substance to
the Purchaser, to the effect that such Transfer is being made pursuant to an
exemption from, or in a transaction not subject to, the registration
requirements of the Securities Act and any State or foreign securities laws.
Seller agrees to the imprinting, so long as appropriate, of substantially the
following legend on certificates representing the Shares or Option Shares:

          THE SHARES OF COMMON STOCK (THE "SHARES") EVIDENCED HEREBY HAVE NOT
     BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
     "SECURITIES ACT"), OR ANY STATE OR FOREIGN SECURITIES LAWS, AND MAY NOT BE
     OFFERED OR SOLD EXCEPT IN COMPLIANCE WITH THE SECURITIES ACT AND SUCH OTHER
     LAWS. BY ITS ACQUISITION HEREOF, THE HOLDER AGREES THAT IT WILL NOT OFFER,
     RESELL, PLEDGE OR OTHERWISE TRANSFER (INDIVIDUALLY AND COLLECTIVELY, A
     "TRANSFER") THE SHARES EVIDENCED HEREBY, EXCEPT (A) PURSUANT TO AN
     EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND ANY
     APPLICABLE FOREIGN OR STATE SECURITIES LAW, OR (B) PURSUANT TO AN EXEMPTION
     FROM REGISTRATION UNDER THE SECURITIES ACT (SUCH AS THE EXEMPTION SET FORTH
     IN RULE 144 UNDER THE SECURITIES ACT, IF AVAILABLE) AND UNDER ANY
     APPLICABLE STATE OR FOREIGN SECURITIES LAWS. IF THE PROPOSED TRANSFER IS TO
     BE MADE OTHER THAN PURSUANT TO CLAUSE (A) ABOVE, THE HOLDER MUST, PRIOR TO
     SUCH TRANSFER, FURNISH TO THE COMPANY AND THE TRANSFER AGENT SUCH
     CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS THEY MAY REASONABLY
     REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
     EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
     REQUIREMENTS OF THE SECURITIES ACT OR ANY STATE OR FOREIGN SECURITIES LAW.

The legend set forth above shall be removed if and when the Shares or Option 
Shares represented by such certificate are disposed of pursuant to an effective 
registration statement under the Securities Act or the opinion of counsel 
referred to above has been provided to Purchaser. The share certificates shall 
also bear any additional legends required by applicable Federal, State or 
foreign securities laws or necessary under applicable Tax laws, which legends 
shall be removed when the Company receives such certifications, legal opinions 
or other information as it may reasonably require to confirm that the same are 
no longer required under the applicable requirements of such securities or Tax 
laws. In connection with any Transfer of Shares or Option Shares by Seller

                                      37
<PAGE>
 
pursuant to an effective registration statement under the Securities Act, Seller
will comply with all prospectus delivery requirements of the Securities Act. 
Purchaser makes no representation, warranty or agreement as to the availability 
of any exemption from registration under the Securities Act with respect to any 
resale of any of the Shares or Option Shares.

          (b)  Stop Transfer Instruction. Purchaser shall be entitled to make a 
               ------------------------
notation on its records and give instructions to any transfer agent for the 
Company's Common Stock in order to implement the restrictions on transfer set 
forth in this Agreement.

          (c)  Reliance. Seller also understands and acknowledges that (i) the 
               --------
Securities are being offered and sold without registration under the Securities 
Act in a transaction that is exempt from the registration provisions of the 
Securities Act and applicable state and foreign securities laws and (ii) the 
availability of such exemption depends in part on, and that the Purchaser will 
rely upon, the accuracy and truthfulness of the representations contained in 
Section 3.22 and Seller hereby consents to such reliance.

     Section 5.18   [Intentionally Omitted].
                     ---------------------

     Section 5.19   Filing or Non-Filing of Section 338 Election. If Purchaser 
                    --------------------------------------------
files, or causes to be filed, an election under section 338 of the United States
Internal Revenue Code with respect to the purchase of the Sub Shares, Purchaser 
covenants and agrees that it will hold Seller harmless for any increased Tax
liability owed by Seller that results from such election. If Purchaser does not
file, or cause to be filed, such an election:

          (a)  Except with the prior written consent of Seller, Purchaser 
covenants and agrees that Sub will not make a distribution out of its earnings 
and profits (as defined for United States tax purposes) during the portion of 
Sub's taxable year (as determined for United States tax purposes) that begins on
the Closing Date and ends on the last day of such year; and 

          (b)  Except with the prior written consent of Seller, Purchaser 
covenants and agrees that, during the portion of Sub's taxable year (as 
determined for United States tax purposes) that begins on the Closing Date and 
ends on the last day of such year, Sub will not sell, transfer or otherwise 
dispose of any of its assets except in the ordinary course of business 
consistent with past practices.

     Section 5.20   Refund of Sub Taxes. Purchaser covenants and agrees that, if
                    -------------------
Sub receives a refund of Taxes paid for its taxable year that includes the 
Closing Date, or any prior taxable year, Purchaser will promptly notify Seller
of such refund. If Seller's United States federal income tax liability is
increased in a taxable year solely as a result of such refund of Taxes, reducing
the amount of Seller's foreign tax credits computed under section 902 of the
United States Internal Revenue Code, Purchaser will, within 30 days of the
Seller's payment of such increased United States federal income tax liability,
pay to Seller the amount of such increased United States federal income tax
liability, plus any interest due thereon; provided, however, that in no event
shall such payment by Purchaser exceed the amount of the refund of Taxes
received by Sub.

whatever nature asserted against Purchaser, or against any of the Transferred 
Assets, by any Person (including but not limited to creditors of Seller or Sub)
by virtue of the failure by Seller to comply with any bulk sales law;

          (e)  any allegation that any information contained in (i) the Proxy 
Statement or (ii) any other materials used by Purchaser in connection with the 
Shareholder Approval which is supplied by Seller expressly for inclusion therein
is false or misleading with respect to any material fact contained therein, or 
omits to state a material fact required to be stated therein or necessary to 
make the statements therein not misleading; and

          (f)  liabilities and obligations of Seller retained by it under 
Section 9.1.

     Section 10.3   Indemnification by Purchaser. Subject to the limitations set
                    ----------------------------
forth in this Agreement, from and after the Closing Date, Purchaser shall 
indemnify and hold harmless Seller, its subsidiaries, officers, shareholders and
directors, from and against any Indemnifiable Damages which they or any of them
may suffer or incur to the extent caused by or arising out of any one or more of
the following:

          (a)  any inaccuracy in or breach of Purchaser's representations and 
warranties set forth herein (or in any agreement, certificate, document or 
instrument delivered by or on behalf of Purchaser in connection herewith) or 
Purchaser's failure to perform in all material respects any of 

                                      45
     
<PAGE>
 
its covenants or agreements set forth herein (or in any agreement, certificate,
document or instrument delivered by or on behalf of Purchaser in connection
herewith), including any failure to pay and perform the Assumed Liabilities when
and as due;

          (b)  any allegation that any information contained in (i) the Proxy 
Statement, or (ii) any other materials used by Purchaser in connection with the 
Shareholder Approval which is not supplied by Seller expressly for inclusion 
therein is false or misleading with respect to any material fact contained 
therein, or omits to state a material fact required to be stated therein or 
necessary to make the statements therein not misleading; and

          (c)  liabilities or obligations related to or arising out of 
Purchaser's ownership, use, possession or operation of the Transferred Assets
and the Business after the Closing Date, other than such liabilities or
obligations for which Purchaser has a right to be indemnified under this
Agreement.

     Section 10.4   Limitation. Notwithstanding anything else contained herein 
                    ----------
to the contrary, neither Seller (on the one hand) nor Purchaser (on other hand)
shall be liable to indemnify the other for any Indemnifiable Damages hereunder 
in respect of any inaccuracies in or breaches of representations and warranties 
until the aggregate amount of such Indemnifiable Damages shall exceed $200,000, 
and then only to the extent of such excess. There shall be no limit on the 
aggregate amount of Indemnifiable Damages for which Seller shall be liable to 
indemnify Purchaser as a result of all inaccuracies in or breaches of the 
representations or warranties set forth in Section 3.13 or 3.14. The maximum 
aggregate amount of Indemnifiable Damages for which Seller shall be liable to 
indemnify Purchaser as a result of all inaccuracies in or breaches of the 
representations or warranties set forth in Section 3.3, 3.30 or 3.31 shall be 
$25,000,000. The maximum aggregate amount of Indemnifiable Damages for which 
either Purchaser or Seller shall be liable to indemnify the other as a result of
all inaccuracies in or breaches of any of their other respective representations
or warranties set forth in, or delivered in connection with, this Agreement 
(other than those previously described in this Section 10.4) shall be 
$3,000,000.

     Section 10.5   Settlement of Claims. Any party making a claim for 
                    --------------------
indemnification under this Article X shall notify the indemnifying party or 
parties of the claim in writing, describing the claim, the amount or estimated 
amount thereof (if determinable), and the basis therefor. The party or parties 
from whom indemnification is sought shall respond to each such claim within 30 
days of receipt of such notice, unless the claim (a) relates to a lawsuit filed 
by a third party, in which case the indemnifying party or parties shall respond 
at least ten (10) days prior to the date a responsive pleading is due (but in no
event later than 30 days after receipt of such notice from the party seeking 
indemnification), or (b) requires an immediate response, as in the case of a 
cease and desist demand by a third party or a notice to show cause, in which 
case the indemnifying party or parties shall respond in a prompt, timely manner 
(but in no event later than 30 days after receipt of such notice from the party 
seeking indemnification). In the event a response to a notice of claim involving
a third party claim is not timely made, a party seeking indemnification may 
respond to such third party claim as it sees fit and seek indemnification 
thereafter pursuant to the terms hereof. The omission of any party seeking 
indemnification to notify the indemnifying party or parties of any such claim

                                      46
<PAGE>
 
shall not relieve the indemnifying party from any liability in respect of such 
claim which it may have to the indemnified party pursuant to this Article X, 
except, and only to the extent that, such failure shall result in material 
prejudice to the indemnifying party or parties. If the claim is based on a claim
by a third party, the indemnifying party or parties will be entitled to 
participate in the negotiation or administration thereof and, to the extent that
such claim relates to the liability of the indemnifying party or parties, to 
assume the defense thereof with counsel reasonably satisfactory to the 
indemnified party. Any indemnified party shall have the right to employ separate
counsel in any such action or claim and to participate in the defense thereto, 
but the fees and expenses of such counsel shall not be at the expense of the 
indemnifying party unless (i) the indemnifying party shall have failed to timely
assume the defense of such claim, or (ii) the employment of such counsel has
been specifically authorized by the indemnifying party in writing, or (iii) the
indemnifying party's counsel, in the reasonable opinion of the indemnifying
party's counsel, is prohibited under applicable rules of professional
responsibility from representing the interests of both parties in such defense.
In the case of the events referred to in clauses (i), (ii) or (iii) of the
preceding sentence, the fees and expenses of such counsel engaged by the
indemnified party shall be the expense of the indemnifying party. If the
indemnifying party or parties respond within the time period set forth above by
notifying the indemnified party that the indemnifying party or parties will
assume the defense of the claim, no indemnification payment shall be due until
the matter giving rise to the indemnity claim is resolved; provided, however,
that any costs and expenses incurred by the indemnified party prior to the
assumption of the defense of such claim shall be paid by the indemnifying party
promptly after notifying the indemnified party of the assumption of the defense.
If the indemnifying party or parties do not assume the defense of the claim, the
indemnified party may assume the defense and (i) receive advancement of costs
and expenses incurred by the indemnified party in connection with the defense of
such claim, and (ii) seek indemnification from time to time as the amount of the
claim for which it is entitled to be indemnified becomes liquidated.
Notwithstanding the foregoing, neither party shall pay, settle or compromise any
such claim or proceeding without the prior written approval of the other party,
which approval shall not be unreasonably withheld or delayed; provided, that the
indemnifying party or parties may pay, settle or compromise any such claim or
proceeding without the consent of the indemnified party to the extent such
payment, settlement or compromise requires solely the payment of money and is
solely the liability of the indemnifying party or parties and provides a full
release and dismissal of the indemnified party from such claim or proceeding. In
connection with any claims based on claims by third parties, the party claiming
indemnification shall cooperate reasonably in the defense, including making
available to the defending party all pertinent information under its control.

                              GENERAL PROVISIONS
                              ------------------

     Section 11.1   Waiver of Conditions to Closing. Anything in this Agreement 
                    -------------------------------
to the contrary notwithstanding, if one or more of the conditions specified in 
Article VII hereof shall not have been satisfied, Purchaser shall have the 
right, in addition to any other right which may be available to it, to waive
such condition in writing and proceed with the transactions contemplated hereby;
and if one or more of the conditions specified in Article VIII hereof shall not
have been satisfied, Seller shall

                                      47
<PAGE>
 
have the right, in addition to any other right which may be available to it, to 
waive such condition in writing and proceed with the transactions contemplated 
hereby. Any such waiver in writing by either Purchaser or Seller shall 
constitute a waiver of its rights under the indemnification provisions of 
Article X with respect to the item or items specifically identified in such 
waiver.

     Section 11.2   Termination. (a) This Agreement may be terminated at any 
                    -----------
time prior to the Closing: (i) by mutual written consent of Purchaser and 
Seller, (ii) by Purchaser in accordance with Section 5.2(a) or by either party 
in accordance with Section 5.12 or Section 11.13; (iii) by either Purchaser or 
Seller if the Closing shall not have occurred on or prior to the date which is 
one hundred twenty (120) days after the Financial Statement Delivery Date (or 
such later date as shall have been consented to by all parties hereto), unless 
the failure of such occurrence shall be due to the failure of the party seeking 
to terminate this Agreement to perform or observe in any material respect the 
covenants, agreements and conditions hereunder to be performed or observed by 
such party at or before the Closing; (iv) by either Purchaser or Seller if the 
Closing shall not have occurred on or prior to December 31, 1996 (the "Final 
Termination Date"), unless the Financial Statement Delivery Date occurs on a 
date later than 30 days after the date of this Agreement, in which case the 
Final Termination Date shall be postponed by a number of days equal to the 
number of days by which the Financial Statement Delivery Date follows the date 
which is 30 days after the date hereof, but in no event by more than 31 days 
(i.e., no later than January 31, 1997); or (v) by Purchaser, on the one hand, or
Seller, on the other hand, if the other party hereto fails to perform or observe
in any material respect any of its covenants, agreements or conditions set forth
herein or if any representation or warranty given or made in this Agreement or 
pursuant hereto by the other party was untrue in any material respect as of the 
date given or made, unless the failure to satisfy such condition(s) shall be due
to the failure of the party seeking to terminate this Agreement to perform or 
observe in any material respect the covenants, agreements and conditions 
hereunder to be performed or observed by such party at or before the Closing.

          (b)  Notwithstanding the foregoing, if this Agreement is terminated 
pursuant to Section 11.2(a)(iii), 11.2(a)(iv) or 11.2(a)(v) and such termination
is not due to the failure of Seller to perform or observe in any material 
respect Seller's covenants, obligations or conditions set forth in this 
Agreement, is not due to a breach of any Seller's representations or warranties 
set forth in this Agreement and is not due to the failure by Seller to deliver 
Financial Statements in a form which the SEC approves to be included in the 
Proxy Statement, Purchaser shall be obligated to reimburse Seller for its 
out-of-pocket expenses incurred in connection with the transactions contemplated
in this Agreement, up to a maximum aggregate amount of $250,000.

          (c)  If this Agreement is terminated by either party pursuant to 
Section 11.2(a)(v) as a result of a breach of any of the party's representations
or warranties set forth in this Agreement, the other party shall be obligated to
reimburse the terminating party for all reasonable out-of-pocket expenses 
incurred by the terminating party in connection with the transactions 
contemplated in this Agreement, but the other party shall not otherwise have any
liability as a result of such breach.

                                      48

          (d)  The provisions set forth in Sections 5.11(a), 5.11(c), 5.11(d), 
11.2(b), 11.2(c), 11.6, 11.10, 11.11, and 11.12 shall survive termination of
this Agreement pursuant to Section 11.2(a). Termination of this Agreement
pursuant to Section 11.2(a), shall not relieve any party hereto from any
liability for any prior breach of, or a misrepresentation under, any
representation, warranty, covenant or other term of this Agreement and shall not
be deemed to constitute a waiver of any available remedy for any such breach or
misrepresentation.

                    -------

     Section 11.5   Successors and Assigns.  This Agreement shall be binding
                    ----------------------
upon and inure to the benefit of the parties hereto and their respective
successors and permitted assigns. No party to this Agreement may assign or
transfer any of its rights or interests under this Agreement to any Person
without the prior written consent of each of the other parties to this
Agreement, and any purported assignment or transfer without such previous
written consent shall be void; provided, however, that at any time prior to
                               --------  -------
Closing, Purchaser may assign all or any portion of its rights or interests but
not its obligation under this Agreement to any Affiliate of Purchaser to the
extent necessary to allow the transfer from Seller of the Sub Shares or all or
any portion of the Transferred Assets, or the grant of the License, to such
Affiliate at Closing.

                    -------------
construed in accordance with the laws of the State of New York.

     Section 11.7   Invalid Provisions.  If any provision of this Agreement is
                    ------------------
held to be illegal, invalid or unenforceable under present or future laws
effective during the term of this Agreement, such provision shall be fully
severable; this Agreement shall be construed and enforced as if such illegal,
invalid, or unenforceable provision had never comprised a part hereof; and the
remaining provisions hereof shall remain in full force and effect and shall not
be affected by the illegal, invalid, or unenforceable provison or by its
severance herefrom. Furthermore, in lieu of such illegal, invalid, or
unenforceable provision, there shall be added automatically as a part of this
Agreement a provision as similar in terms to such illegal, invalid, or

parties hereto are limited by the terms of this Agreement or matters are

this Agreement are cumulative to, and not exclusive of, any rights or remedies
otherwise available under applicable law (it being understood that the provision
of this Agreement set forth the exclusive remedies for a breach of the
representations and warranties set forth in Articles III and IV and a breach of
the covenants set forth in Section 5.1). No failure on the part of any party to
exercise, or delay in exercising, any right hereunder shall be deemed a waiver
thereof, nor shall any single or partial exercise preclude any further or other
exercise of such or any other right. Purchaser and Seller shall be entitled to
seek any equitable remedy to the extent such remedy is available under
applicable law.

     Section 11.11  Dispute Resolution.
                    ------------------

          (a)  Mediation. If a dispute arises between the parties which cannot 
               ---------
be resolved by negotiation, each of Seller and Purchaser agree to designate two 
representatives to participate in at least four hours of mediation before 
pursuing any other remedies. The mediation shall be conducted by the New York 
office of United States Arbitration & Mediation, Inc. or another mutually 
acceptable service, with the costs of the mediator equally split by the parties.
Mediation involves each side of a dispute conferring with an impartial person to
attempt to reach a voluntary settlement, with no formal court procedures or
rules of evidence and with the mediator having no power to render a binding
decision or force an agreement between the parties.

          (b)  Arbitration Proceedings. If the matter has not been resolved 
               -----------------------
pursuant to the foregoing procedures within thirty (30) days after the first 
meeting of the parties' designated representatives (which period may be extended
by mutual agreement), the matter shall be referred to arbitration conducted in 
accordance with the provisions of the Federal Arbitration Act (9 U.S.C. (S)(S) 
1-16), and in accordance with the Center for Public Resources, Inc.'s Rules (the
"Rules of Arbitration") for Non-Administered Arbitration of Business Disputes,
by a single arbitrator selected in accordance with such Rules of Arbitration.
The arbitrator to be selected under this Section 11.11 shall, unless the parties
mutually agree otherwise, be a person: (i) who meets the qualifications set 
forth in Rule 7 of the Rules of Arbitration; and (ii) who has past experience in
settling complex litigation involving claims relating to matters similar to 
those set forth in this Agreement. Any discovery that may be permitted will be 
limited to (i) 60 days, (ii) single depositions of no more than three 
individuals per side who are directly involved, and (iii) a single, reasonable 
request for directly relevant documents.

          (c)  Place of Arbitration. Any arbitration proceedings hereunder shall
               --------------------
be conducted in New York, New York or at such other location as the parties may 
agree.

          (d)  Judgments. Any arbitration award hereunder shall be final and 
               ---------
binding upon the parties, and judgment may be entered thereon, upon the 
application of either party, by any court having jurisdiction.

          (e)  Expenses. Each party shall be entitled to be reimbursed by the 
               --------
other party for costs and expenses incurred in connection with commencing any 
action under this Section 11.11, including reasonable attorneys' fees and 
arbitrators' fees, if and to the extent determined by the arbitrator or 
arbitrators arbitrating any such action.

          (f)  Equitable Remedies. Notwithstanding anything else in this Section
               ------------------
11.11 to the contrary, Purchaser and Seller shall be entitled to seek any 
equitable remedies available under applicable law from any court of competent 
jurisdiction, and the order or judgment of any such court shall be binding in 
any proceeding pursuant to this Section 11.11.

          (g)  Court Proceedings. At any time within 15 days after a final 
               -----------------
resolution of a dispute through arbitration as provided above, either party (the
"Rejecting Party") may, by notice

                                      51
<PAGE>
 
to the other, reject the decision of the arbitrator. If neither party rejects 
the arbitral decision within such 15 day period, it shall become valid, 
binding, enforceable and irrevocable, to the maximum extent allowed by law. If 
the arbitral decision is rejected, it shall have no force or effect, except as 
provided below, and either party may commence an action to resolve such 
dispute in the Commercial Division (or, if recourse to such division is not 
available for any reason, in the appropriate division) of the New York State 
court in New York County (the "Court"). The parties submit to the exclusive 
jurisdiction of the Court for this purpose, agree not to pursue trial of a 
dispute in any other court, waive any right to trial by jury, and stipulate that
discovery shall be limited, to the extent permitted by the Court, to an 
additional round of discovery as described above in paragraph (b). Evidence 
obtained in the arbitration proceeding, including the transcript thereof, will 
be admissible as evidence in the Court, but no evidence that indicates the 
result of the arbitration shall be admissible in the Court, and no delay 
occasioned by the arbitration proceedings will be used to the prejudice of any 
party in Court proceedings. If the ultimate resolution of the dispute in the
Court and any appeal therefrom (an "Ultimate Resolution") is not materially more
favorable to the Rejecting Party than the arbitral decision, then the Rejecting
Party shall, within 3 days from the date of such Ultimate Resolution, reimburse
the other party for all of its out-of-pocket costs and attorney's fees for the
arbitration, the COurt proceeding and any appeal therefrom. If the Ultimate
Resolution is materially more favorable to the Rejecting Party, then each party
will bear its own costs and attorney's fees, subject to any allocation by the
Court or appellate court, and any allocation of costs (but not the decision on
the merits) in the arbitral decision will be given effect. For purposes of this
paragraph (g), an Ultimate Resolution which involves solely the grant of
damages, costs and/or attorney's fees shall not be deemed materially more
favorable to the Rejecting Party unless, as applicable (i) the net aggregate
amount of such damages, costs and/or attorney's fees awarded to the Rejecting
Party in the Ultimate Resolution exceeds 110% of the net aggregate amount of
damages, costs and/or attorney's fees awarded to the Rejecting Party in the
arbitral decision, or (ii) the net aggregate amount of such damages, costs
and/or attorney's fees assessed against the Rejecting Party in the Ultimate
Resolution is less than 85% of the net aggregate amount of damages, costs and/or
attorney's fees assessed against the Rejecting Party in the arbitral proceeding.

          (h)  Damages.  No party shall seek, and no arbitrator or Court shall 
               -------
be authorized to award, any punitive, exemplary, statutorily enhanced or similar
damages in excess of compensatory damages relating to any matter under, arising 
out of, in connection with or relating to this Agreement in the arbitration or 
Court proceedings set forth herein or in any other forum. The parties intend 
that this agreement with regard to dispute resolution be valid, binding,
enforceable and irrevocable.

          (i)  Other Transaction Documents.  The provisions of this Section 
               ---------------------------
11.11 shall apply to any dispute under any other Transaction Document unless 
expressly provided to the contrary therein.

     Section 11.12  Expresses.  Unless otherwise expressly set forth in this 
                    ---------
Agreement, Purchaser and Seller shall each bear its own respective accounting
and legal fees and other costs and expenses incurred in connection with the
negotiation and preparation of this Agreement and the consummation of the
transactions contemplated in this Agreement.

     Section 11.13  Disclosure Schedules, Transferred Assets. Notwithstanding 
                    ----------------------------------------
any other provision set forth in this Agreement, Seller shall at any time prior
to the date which is fifteen (15) days after the date of this Agreement have the
right to provide to Purchaser a revised version of Appendix I, Appendix II and
any of the Schedules to this Agreement described in Article III. In addition,
Purchaser shall at any time prior to the date which is fifteen (15) days after
the date of this Agreement have the right to provide to Seller a revised version
of any of the Schedules to this Agreement described in Article IV. Each party to
this Agreement shall have the right, in its sole and absolute discretion, to
terminate this Agreement by giving written notice of such termination delivered
to the other party within five (5) days after receiving any revised Appendix or
Schedule delivered pursuant to this Section 11.13. Any revised version of
Appendix I and Appendix II and any revised version of any of the Schedules to
this Agreement delivered pursuant to this Section 11.13 shall be deemed to have
been delivered on the date of this Agreement; provided, that such delivery shall
not limit or affect in any way Purchaser's right to terminate this Agreement
