     SECTION 1.03. Assumed Liabilities. On the terms and subject to the
conditions set forth in this Agreement, at the Closing, Buyer shall assume from

reasonable detail showing Company's estimate of the Assumed Liabilities as of

comments or questions that Buyer may have with respect to such schedule. From
and after the Closing, Buyer shall have the right to confirm the accuracy of

such review, Buyer believes that the Assumed Liabilities as of the Closing Date
exceed $30,000,000, the parties agree to discuss in good faith Buyer's
comments, and any disputes that the parties cannot resolve within 2 business
days will be resolved expeditiously before the Bankruptcy Court. If the Assumed
Liabilities as of the Closing Date, as reflected on the schedule prepared by
Company or as revised upon resolution of any comments by Buyer, exceed
$30,000,000, then the provisions of Section 5.14 shall apply.

obligations or commitments of Sellers (or any predecessors of Sellers or any
prior owners of all or part of their businesses and assets) whether known or
unknown, absolute, accrued, contingent or otherwise (whether or not related to
the Business or the Acquired Assets). For the avoidance of doubt, the Excluded

     all costs incurred in defending such claims, actions, causes of action and
     liabilities) related to the factual matters asserted in the cases set
     forth on Schedule 1.04(a)(ii) (the "Existing Claims");

          (iii) any obligation of Sellers with respect to indemnification of

     including the mortgages on the real estate facilities described in Section
     5.15;

          (v) any and all claims, actions, causes of action and liabilities of
     any type, whether known or unknown, relating to payments of an aggregate

     to the Closing;

     existing on or prior to the Closing Date whether arising under
     Environmental Laws (or in connection with the Release or threatened
     Release of any Contaminant); and

          (viii) any and all claims, actions, causes of actions and liabilities
     of any type, whether known, unknown, relating to stock options, the
     employee stock purchase plan and any transaction bonuses described in

obligations not being assumed being herein referred to as the "Excluded
Liabilities").

Assets, Buyer shall pay to Company at the Closing the amount in cash equal to

taken into account under Section 1060 of the Code) shall be allocated among the
Acquired Assets acquired by Buyer as agreed upon by Buyer and Company within 90
days after the Closing. Buyer and Company agree to be bound by such allocation

effect. Each of Company and its Subsidiaries has fulfilled and performed in all

made available to Buyer by Sellers, when taken as a whole, contains, or at the

the Closing will omit, to state a material fact required to be stated herein or

                                   ARTICLE 5
                                   COVENANTS

     SECTION 5.01. Conduct of the Business. (a) From the date hereof until the
Closing, Company shall (and shall cause each of its Subsidiaries to):

          (i) maintain its existence in good standing;

          (ii) maintain the general character of its business and properties
     and conduct its business in the ordinary and usual manner consistent with
     past practices, except as expressly permitted by this Agreement;

          (iii) maintain business and accounting records consistent with past

          (iv) use all reasonable efforts (A) to preserve its business intact,

     respect to the payment of accounts payable and collection of accounts
     receivables); with respect to any Taxes that will be Assumed Liabilities,

     ordinary course of business and consistent with past practice;

          (x) except in connection with the sale, licensing or other
     distribution of Company's products in the ordinary course of business and
     consistent with past practice, sell, assign, transfer, license,
     sublicense, pledge or otherwise encumber any of the Intellectual Property
     Rights;

          (xi) except as required by law or as contemplated hereby, enter into,
     adopt or amend in any material respect or terminate any Benefit
     Arrangement or any other agreement, plan or policy involving Company or
     its Subsidiaries, and one or more of its directors, officers or employees,
     or materially change any actuarial or other assumption used to calculate
     funding obligations with respect to any pension plan, or change the manner

     director, executive officer or other key employee or pay any benefit or

     this Agreement to any such Person; or

          (xiii) announce an intention, commit or agree to do any of the
     foregoing.

     SECTION 5.02. Marketing Period. In addition to the marketing efforts
carried out to date, from and after the date of the Interim Order, Company
shall solicit "higher or better" offers for the Business, pursuant to the
bidding procedures set forth on Exhibit C hereto or to such additional
procedures for soliciting "higher or better" offers, which procedures are
approved by the


                                      -27-



Bankruptcy Court in the Interim Order (the "Bidding Procedures"). Except as
provided for in the Bidding Procedures, Company shall not amend, waive, modify
or supplement in any material respect the Bidding Procedures. If Company
determines in the good faith exercise of its business judgment that a Competing
Transaction provides a greater net benefit to the estates of Sellers, after
deduction (in the case of bids other than that of Buyer) of the Topping Fee and
of $500,000 (the maximum amount of the fees and expenses of Buyer to be paid by
Company herein), and such Competing Transaction is approved by the Bankruptcy
Court, Company shall have the right to enter into an agreement providing for
the Competing Transaction and to terminate this Agreement pursuant to Section
9.01(a)(ii).

     SECTION 5.03. Bankruptcy Court Approvals. (a) Company hereby confirms that
it is critical to the process of arranging an orderly sale of Company's assets
to proceed by selecting Buyer to enter into this Agreement in order to present
the Bankruptcy Court with arrangements for obtaining the highest realizable
prices for such assets and that, without Buyer's having committed substantial
time and effort to such process, the estates of Company would have to employ a
less orderly process of sale and thereby both incur higher costs and risk
attracting lower prices. Company further confirms that the undertaking of Buyer
to pay the Purchase Price while allowing this Agreement to be subject to
competitive bidding gives the estate the assurance of a minimum purchase price,
and restricts Buyer's options in a manner that no reasonable Person would
consent absent assurance of payment of the Topping Fee and expenses set forth
herein. Accordingly, the contributions of Buyer to the process have
indisputably provided very substantial benefit to the estate of Company.
Company acknowledges that Buyer would not have invested the effort in
negotiating and documenting the transaction provided for herein and incurring
duties to pay its outside advisors and to commit to pay the Purchase Price if
Buyer was not entitled to the Topping Fee plus reasonable fees and
disbursements of its advisors incurred as a result of Buyer's attempt to
purchase the Acquired Assets as provided in this Agreement, if Buyer is not the
successful bidder for the Acquired Assets.

     (b) As promptly as practicable after the date hereof, Company shall file
and serve motions with the Bankruptcy Court seeking

          (i) an order (the "Interim Order")

               (A) approving the Topping Fee and all other payments to Buyer
          arising under this Agreement as joint and several obligations of
          Company having priority as an administrative expense in their cases
          before the Bankruptcy Court,


                                      -28-



               (B) approving the Bidding Procedures relating to the sale of the
          Acquired Assets under Sections 363 and 365 of the Bankruptcy Code,
          and the adequacy of notice to creditors and parties in interest for
          the approval of the transactions contemplated hereby and thereby, and

               (C) setting a date for a hearing on the asset sale; and

          (ii) an order (the "Section 363/365 Sale Order")

               (A) authorizing Company to sell the Acquired Assets to Buyer
          pursuant to this Agreement and Sections 363 and 365 of the Bankruptcy
          Code, free and clear of all Liens in or on the Acquired Assets
          (including any and all "claims and interests" in the Acquired Assets
          within the meaning of Section 363(f) of the Bankruptcy Code), other
          than Liens and claims related to the Assumed Liabilities and
          Permitted Exceptions and otherwise free and clear of claims and
          liabilities, such that Buyer shall not, among other things, incur any
          liability with respect to any Existing Claim, Excluded Liability or
          otherwise as a successor to the business of Company, and

               (B) authorizing, among other things, Company, pursuant to
          Section 365 of the Bankruptcy Code, to assume and to assign to Buyer
          the Section 365 Assumed Rights, which shall include provisions, upon
          notice to all licensors of Intellectual Property and all governmental
          and other entities that have issued permits, licenses or
          authorizations to Company, for their assignment to Buyer under
          Section 365 of the Bankruptcy Code free and clear of claims,
          obligations and defaults which occurred on or prior to the effective
          time of such assignment.

     (c) Company shall use commercially reasonable efforts to obtain the
Interim Order no later than February 28, 2001, and the Section 363/365 Order no
later than March 31, 2001. The Interim Order and the Section 363/365 Order
shall be in forms reasonably acceptable to Buyer and Company, and the motions
relating to the Interim Order and the Section 363/365 Order shall be in form
and substance satisfactory to Buyer.

     (d) Subject to the Interim Order, Company shall promptly make any filings,
take all actions, and use all reasonable efforts to obtain any and all other
approvals and orders necessary or appropriate for consummation of the


                                      -29-

transactions contemplated hereby, subject to their obligations to comply with
any order of the Bankruptcy Court.

     (e) If an appeal is taken, or a stay pending appeal is requested or
reconsideration is sought, from either the Interim Order or the Section 363/365
Order, Company shall immediately notify Buyer of such appeal or stay request
and shall provide to Buyer within one business day a copy of the related notice
of appeal or order of stay or application for reconsideration. Company shall
also provide Buyer with written notice and copies of any other or further
notice of appeal, motion or application filed in connection with any appeal
from or application for reconsideration of, either of such orders and any
related briefs. Company shall use all reasonable efforts to defend against such
appeals or requests for stay or modification.

     (f) Company shall notify, as is required by the Bankruptcy Code, all
parties entitled to notice of the Section 363/365 Motion, the Interim Motion,
the Interim Order and/or the Section 363/365 Order, as modified by orders in
respect of notice which may be issued at any time and from time to time by the
Bankruptcy Court.

     SECTION 5.04. Access and Information. After entry of the Interim Order,
Company shall afford to Buyer and to Buyer's financial advisors, legal counsel,
accountants, consultants, financing sources and other authorized
representatives reasonable access during normal business hours throughout the
period prior to the Closing Date to the books, records, properties and
personnel of Company and, during such period, shall furnish as promptly as
practicable to Buyer any and all such information as Buyer may reasonably may
request, including all pleadings and other documents or schedules filed with
the Bankruptcy Court, provided that (a) such access does not unreasonably
interfere with the normal operations of Company or its business, (b) Company
need not disclose any information that Company concludes (based upon advice of
counsel) is privileged or confidential in connection with the Existing Claims,
and (c) all requests for information and access to Company's facilities, and
all proposed contacts with Company personnel shall be approved in advance
(which approval shall not unreasonably be withheld) by its Chief Executive
Officer, General Counsel or Chief Financial Officer.

     SECTION 5.05. Books and Records. (a) Buyer agrees to make copies of all
the business records and files being transferred to Buyer pursuant to this
Agreement and to retain such copies for seven years after the Closing.

     (b) From and after the Closing under this Agreement, Buyer shall allow
Company and any of its directors, officers, employees, counsel,
representatives, accountants and auditors (collectively, the "Company


                                      -30-



Representatives") access to Transferred Employees and all business records and
files of Company or its business that are transferred to Buyer in connection
herewith, which are reasonably required by such Company Representatives in
order to complete the Chapter 11 Case and resolve the Existing Claims, during
regular business hours and upon reasonable notice at Company's former offices
or elsewhere as reasonably required and the Company Representatives shall have
the right to meet with such Transferred Employees and to make copies of any
such records and files; provided, however, that any such access or copying
shall be had or done in such a manner so as not to unreasonably interfere with
the normal conduct of Buyer's business or operations. This Section 5.05 shall
cease to be enforceable upon the later of (i) the date Company completes the
Chapter 11 Case and (ii) the 9 month anniversary of the Closing.

     SECTION 5.06. All Reasonable Efforts. Subject to the terms and conditions
herein, except as provided by the Bankruptcy Code, the Bankruptcy Rules or any
other orders entered or approvals or authorizations granted by the Bankruptcy
Court in the Chapter 11 Case, including any order contemplated hereby, each of
the parties hereto agrees to use all reasonable efforts to take, or cause to be
taken, all action and to do, or cause to be done, all things necessary, proper
or advisable under applicable laws and regulations, to consummate the
transactions contemplated by this Agreement. In further and not in limitation
of the foregoing, each party hereto agrees to make an appropriate filing of a
Notification and Report Form pursuant to the HSR Act with respect to the
transactions contemplated hereby as promptly as practicable and in any event
within 10 business days of the date hereof and to supply as promptly as
practicable any additional information and documentary material that may be
requested pursuant to the HSR Act and to take such actions as may be reasonably
necessary to cause the expiration or termination of the applicable waiting
periods under the HSR Act as soon as practicable, provided that nothing
contained herein shall be interpreted or construed as requiring Buyer to sell,
dispose of, transfer or license any of its assets or properties or to take any
other action which Buyer concludes in its sole discretion would be detrimental
to Buyer or its business in order to facilitate such expiration or termination.

     SECTION 5.07. Further Assurances. In addition to the provisions of this
Agreement, from time to time after the Closing Date, Company and Buyer will use
all reasonable efforts to execute and deliver such other instruments of
conveyance, transfer or assumption, as the case may be, and take such other
action as may be reasonably requested to implement more effectively the
conveyance and transfer of the Acquired Assets to Buyer and the assumption of
the Assumed Liabilities by Buyer. Without limiting the generality of the
foregoing, at Buyer's request, Company shall file appropriate motions in the
Bankruptcy Court for the assumption and assignment to Buyer of any executory
contracts and leases which


                                      -31-



were not identified in an exhibit to the Section 363/365 Order, and Company
shall take such steps, as shall be required to assure that Buyer shall assume
such agreements under Section 365 of the Bankruptcy Code free and clear of all
claims, obligations and defaults which occurred as of or prior to the effective
time of such assignment. Buyer and Company hereby irrevocably consent to the
personal and subject-matter jurisdiction of the Bankruptcy Court for all
purposes necessary to effectuate this Section. Company will seek to include in
any plan of reorganization in the Chapter 11 Case supported by it, provision
for retained jurisdiction of the Bankruptcy Court to effectuate this Section
5.07, and will use all reasonable efforts to oppose any plan of reorganization
which fails to include such provisions.

     SECTION 5.08. Public Announcements. Buyer and Company shall consult with
each other before issuing any press release or making any public statement with
respect to this Agreement or the transactions contemplated hereby, and except
as may be required by applicable law or any listing agreement with any national
securities exchange, will not issue any such press release or make any such
public statement prior to such consultation.

     SECTION 5.09. Notices of Certain Events. (a) Company shall promptly notify
Buyer of damage or destruction by fire or other casualty of any material
Acquired Asset or if any material Acquired Asset becomes the subject of any
proceeding or, to the knowledge of Company, threatened proceeding for the
taking thereof or any part thereof or of any right relating thereto by
condemnation, eminent domain or other similar governmental action.

     (b) The Company shall give prompt notice to Buyer, and Buyer shall give
prompt notice to the Company, of (i) the occurrence, or non-occurrence, of any
event which would be likely to cause (A) any representation or warranty
contained in this Agreement to be untrue or inaccurate in any material respect,
(B) any covenant, condition or agreement contained in this Agreement not to be
complied with or satisfied, or (C) termination rights to be triggered under
Article 9; and (ii) any failure of the Company or Buyer, as the case may be, to
comply with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it hereunder; provided that the delivery of any notice pursuant
to this Section 5.10(b) shall not limit or otherwise affect the remedies
available to the party receiving such notice.

     SECTION 5.10. Name Change. Within 45 days after the Closing, Company
agrees to use all reasonable efforts to cause Company to cease doing business
under any name using the word "Quintus," and, if practicable without seeking
stockholder approval, to change Company's legal name to some name not using the
word "Quintus."


                                      -32-



     SECTION 5.11. Permits. Prior to the Closing Date, Company shall use all
reasonable efforts to obtain consents to the transfer of such permits which are
transferable to Buyer at or prior to Closing. Without limiting the requirements
of Section 8.03, prior to and after the Closing, Company shall cooperate with
Buyer with respect to the transfer of all permits.

     SECTION 5.12. Transfer Taxes. To the fullest extent permitted by Section
1146(c) of the Bankruptcy Code and other applicable law, the making or delivery
of any instrument of transfer pursuant hereto shall not be taxed under any law
imposing a stamp tax or similar tax, and the instruments transferring the
Acquired Assets to Buyer shall contain the following endorsement:

          "Because this [instrument] has been authorized pursuant to Order of
          the United States Bankruptcy Court for the District of Delaware
          relating to a plan of reorganization of the Grantor, it is exempt
          from transfer taxes, stamp taxes or similar taxes pursuant to 11
          U.S.C. ss.1146(c)."

     If sales, use or other similar transfer Taxes are assessed in the United
States at Closing or at any time thereafter solely as a result of the transfer
of any other Acquired Assets pursuant to this Agreement, such Taxes incurred as
a result of the transactions contemplated hereby shall be paid by Company. If
sales, use or other similar Taxes are assessed in any jurisdiction outside the
United States at Closing or at any time thereafter solely as a result of the
transfer of any Acquired Assets of any Foreign Subsidiary pursuant to this
Agreement, such Taxes shall be paid (i) by Company, to the extent such Taxes
would have been payable if Buyer had purchased all of the outstanding stock of
Company's Foreign Subsidiaries (rather than purchasing assets and liabilities
of such Foreign Subsidiaries as set forth in Article 1) and (ii) by Buyer for
the balance of such Taxes. Buyer and Company shall cooperate in providing each
other with any appropriate resale exemption certifications and other similar
documentation.

     SECTION 5.13. Consents. Company shall use all reasonable efforts to obtain
the consents pertaining to the Assigned Assets listed on Schedule 3.04;
provided that Company shall not make any agreement or understanding adversely
affecting the Business or the Assigned Assets after the Closing as a condition
for obtaining any such consent except with the prior written authorization of
Buyer.

     SECTION 5.14. Excess Liabilities. At the Closing, if Company's liabilities
described in paragraph 1 of Schedule 1.03 exceed $30,000,000, Buyer may elect
not to assume such liabilities of Company to the extent required to reduce such
liabilities assumed to $30,000,000.


                                      -33-



     SECTION 5.15. Acton, Massachusetts Real Property and Facility. Buyer has
advised that it does not desire to acquire Company's real estate facilities at
Acton, Massachusetts. The parties agree that (i) the Acton real estate will be
an Excluded Asset and (ii) as promptly as reasonably practical after the date
hereof, the parties will negotiate and enter into a three-year lease of the
Acton real estate from Company to Buyer at market rental and on market terms,
such lease to be effective at the Closing of the transactions contemplated by
this Agreement. As promptly as reasonably possible after negotiation of that
lease, (i) Company shall select a real estate appraiser knowledgeable about the
Acton real estate market, (ii) Buyer shall select a real estate appraiser
knowledgeable about the Acton real estate market and (iii) the appraisers so
selected shall select a third real estate appraiser knowledgeable about the
Acton real estate market, and such appraisers shall independently provide
appraisals of the fair market value of the Acton real estate, which appraisals
shall take into account the three-year lease of the property to Buyer and the
mortgages on the property. The cost of these appraisals will be split equally
between Buyer and Company. The parties agree that (x) the average of the three
appraisals shall be considered the fair market value of the Acton real estate
for purposes of this Agreement, (y) in recognition of the fact that the Acton
real estate will be an Excluded Asset, the Purchase Price shall be reduced by
80% of the average of the three quotes and (z) Company will have the right to
sell the Acton real estate, subject to the lease, for its own account.

     SECTION 5.16. Buyer Option to Take Stock of Foreign Subsidiaries.
Notwithstanding the provisions of Sections 1.01 and 1.02, Buyer shall have the
option, upon written notice to Company at least five days prior to the Closing
Date, to purchase all outstanding shares of capital stock of either or both
Foreign Subsidiaries in lieu of the assets and liabilities of such Subsidiary,
provided that if such option is exercised with respect to a Foreign Subsidiary
and any liability of such Foreign Subsidiary would otherwise count toward the
$30,000,000 limit set forth on Schedule 1.03, such liabilities shall continue
to be so counted and such stock shall be deemed Acquired Assets.

     SECTION 5.17. Employee Retention. Buyer agrees to make offers of
employment to employees in Company's Engineering, Worldwide Customer Support
Services and Worldwide Sales and Distribution organizations including cash
incentives in an aggregate amount of at least $10,000,000 and equity incentives
consisting of options to purchase shares of Buyer common stock with an
aggregate Black-Scholes value of $10,000,000, and Buyer and Company agree to
use all reasonable efforts to induce such employees to accept such offers of
employment.


                                      -34-



     SECTION 5.18. Taxes. Company agrees to use all reasonable efforts to
account for Taxes that will be Assumed Liabilities separately from other
Assumed Liabilities, and to deliver a schedule of such Taxes to Buyer at the
Closing.

                                   ARTICLE 6
                             EMPLOYEES AND BENEFITS

     SECTION 6.01. Employees and Offers of Employment. (a) On or prior to the
Closing Date, Buyer shall offer employment to all employees of the Business;
provided, that Buyer may terminate at any time after the Closing Date the
employment of any employee who accepts such offer; provided, however, that
Buyer is solely responsible for any WARN Act notification and any liability
under the WARN Act for any failure to notify employees, if any, relating to any
termination of any of the employees on or after the Closing as a result of
actions taken by Buyer. For purposes of the foregoing, Buyer acknowledges the
prior terminations of employment by Company, including the reduction in force
in December 2000. Any such offers shall be at salary or wage and benefit levels
that are substantially comparable in the aggregate to the wage, benefits and
severance protection made available by Buyer to similarly situated employees of
Buyer, provided that nothing herein shall prevent Buyer from modifying the
salary, wages and benefits at any time after the Closing Date. The employees
who accept and commence employment with Buyer are hereinafter collectively
referred to as the "Transferred Employees." Company will not take, and will
cause each of its Subsidiaries not to take, any action which would impede,
hinder, interfere or otherwise compete with Buyer's effort to hire any
Transferred Employees.

     (b) For a period of six months following the Closing Date, Buyer shall
provide severance benefits no less favorable than those set forth on Schedule
3.14. In addition, Buyer agrees that it shall assume the obligations of Company
under the Executive Severance Plan and Retention Bonus Programs described in
Schedule 3.14(a)(1) and (2).

     SECTION 6.02. Company Employee Benefit Plans. Accrued benefits or account
balances of Transferred Employees under the Benefit Arrangements shall be fully
vested as of the Closing Date.

     SECTION 6.03. Buyers Benefit Plans. (a) Buyer or one of its Affiliates
will recognize all service of the Transferred Employees with Company (or their
predecessors) or any of their Affiliates, for purposes of eligibility to
participate in and to vest under those employee benefit plans, in which the
Transferred Employees are enrolled by Buyer or one of its Affiliates
immediately after the


                                      -35-



Closing Date. Buyer shall cause all pre-existing condition exclusions under any
medical and dental plans made available by Buyer to Transferred Employees to be
waived in respect of such Employees. Buyer will in good faith determine whether
to take into account expenses incurred by Transferred Employees under Company's
medical and dental plans during the year that includes the Closing Date for
purposes of satisfying deductible and coinsurance requirements and satisfaction
of out-of-pocket provisions of Buyer's medical and dental plans in which
Transferred Employees participate for such year, provided that the foregoing
shall not require Buyer to do so.

     (b) Company's 401(k) Plan shall be terminated immediately prior to the
Closing Date. Such termination shall be effected in accordance with applicable
law and regulations, and Company shall make or cause to be made, any required
filings in connection therewith. Buyer or one of its Affiliates shall take such
actions as may be necessary to make available to the Transferred Employees the
opportunity to roll over eligible rollover distributions from the Company
401(k) Plan to a defined contribution plan maintained by Buyer or one of its
Affiliates. Buyer or one of its Affiliates may require, as a condition to the
acceptance of any such eligible rollover distribution, evidence satisfactory to
Buyer of the qualified status of the 401(k) Plan, including a copy of a
favorable determination letter from the Internal Revenue Service. Company may
require, as a condition to the transfer of such eligible rollover distribution,
transfer evidence satisfactory to Company of the qualified status of Buyer's
defined contribution plan, including a copy of a favorable determination letter
from the Internal Revenue Service. Each of the parties hereto shall pay its own
expenses in connection with such transfer. Neither Buyer nor any of its
Affiliates shall assume any other obligations or liabilities arising under or
attributable to Company's 401(k) Plan, the same to be retained or assumed by
Company.

     (c) Buyer shall make COBRA continuation coverage available under Buyer's
group health plans or Company's group health plans, as applicable, to the
extent permitted by such plans, the underlying insurance policies and
applicable law to each former employee of Company whose employment with Company
was terminated prior to Closing and each of their qualified beneficiaries whose
qualifying event occurred prior to or in connection with the Closing. For
purposes of this paragraph, the foregoing terms shall have the meanings given
to them under IRS regulations under Code Section 4980B.

     (d) Buyer shall make COBRA continuation coverage available under Buyer's
group health plans to each Transferred Employee whose employment with Buyer or
its Affiliates is terminated after the Closing and each of their qualified
beneficiaries whose qualifying event occurred after the Closing Date.


                                      -36-



For purposes of this paragraph, the foregoing terms shall have the meanings
given to them under IRS regulations under Code Section 4980B.

                                   ARTICLE 7
                                  TAX MATTERS

     SECTION 7.01. Tax Cooperation. Buyer and Company agree to furnish or cause
to be furnished to each other, upon request, as promptly as practicable, such
information and assistance relating to the Business and the Acquired Assets
(including access to books and records) as is reasonably necessary for the
filing of all Tax Returns, the making of any election relating to Taxes, the
preparation for any audit by any taxing authority, and the prosecution or
defense of any claim, suit or proceeding relating to any Tax. Buyer shall
retain all books and records with respect to Taxes pertaining to the Business,
the Acquired Assets or the transactions contemplated hereby for a period of at
least seven years following the Closing Date. Company shall retain any records
retained by Company related to Taxes until liquidation. Each party shall
provide the other with at least thirty days prior written notice before
destroying or transferring custody of any such books and records, during which
period the party receiving such notice can elect to take possession, at its own
expense, of such books and records.

     SECTION 7.02. Tax Reporting. Buyer will in good faith determine whether to
prepare and furnish to each Transferred Employee a combined Form W-2 which
shall reflect all wages and compensation paid to such employees for that
portion of the calendar year in which the Closing Date occurs during which such
employees were employed by Company as well as that portion of the year employed
by Buyer (if any), with Buyer treated as a "successor employer" for purposes of
Taxes imposed under the United States Federal Unemployment Tax, United States
Federal Insurance Contribution Act and any other employment related Tax;
provided that nothing in the foregoing shall require Buyer to do so. If Buyer
does the foregoing, Buyer shall send to the appropriate Social Security
Administration office a duly completed Form W-3 and accompanying copies of the
duly completed Form W-2.

                                   ARTICLE 8

     Adverse Effect shall be true and correct and each of the representations

     Adverse Effect shall be true and correct except for breaches of such

     effect on Buyer, its financial condition and results of operations, and
     its ability to perform its obligations under this Agreement and consummate
     the transactions contemplated by this Agreement, in each case, on and as
     of the Closing with the same effect as though such representations and
