the Company and the Subsidiaries are duly authorized, validly issued, fully paid
and nonassessable. There are no outstanding or authorized options, warrants,

         7.1 ACCESS TO INFORMATION; COOPERATION.

              (a) ACCESS TO INFORMATION. Following the Closing, each Party shall
afford to the other Party and to the other Party's Affiliates, authorized
accountants, counsel and other designated representatives reasonable access
(including using reasonable efforts to give access to third parties possessing

business hours to all non-privileged records, books, contracts, instruments,
documents, correspondence, computer data and other data and information

(collectively, "INFORMATION") within the possession or control of such Party or
its Affiliates, relating to the Company, the Subsidiaries or their businesses or
operations prior to the Closing, insofar as such access is reasonably required
by the other Party. Seller may withhold Information based on privilege only if
the privilege runs to Seller or its affiliates excluding the Company.
Information may be requested under this Section 7.1(a) for, without limitation,
any financial reporting and accounting matters, preparing or verifying financial
statements, preparing and filing of any Tax Returns, prosecuting any claims for
refund, defending any Tax claims or assessment, preparing securities law or
exchange filings, prosecuting, defending or settling any litigation,
Environmental Matter or insurance claim, performing this Agreement and the
transactions contemplated hereby, and all other proper business purposes.

              (b) ACCESS TO PERSONNEL. Following the Closing, each Party shall
use reasonable efforts to make available to the other Party, upon written
request, such Party's and its Affiliates' officers, directors, employees and

                                       12


<PAGE>

agents to the extent that such persons may reasonably be required in connection
with any legal, administrative or other proceedings in which the requesting
Party may from time to time be involved relating to the Company or the
Subsidiaries or their respective businesses or operations prior to the Closing
or for any other matter referred to in Section 7.1(a).

              (c) REIMBURSEMENT. A Party providing Information or personnel to
the other Party under Section 7.1(a) or (b) shall be entitled to receive from
the recipient, upon the presentation of invoices therefor, payments for such
amounts, relating to supplies, disbursements and other out-of-pocket expenses,
as may be reasonably incurred in providing such Information; provided, however,
that no such reimbursements shall be required for the salary or cost of fringe
benefits or similar expenses pertaining to attorneys, accountants, employees or
directors of the providing Party or its Affiliates.

              (d) CONFIDENTIALITY. Each of the Buyer and the Seller shall hold,
and shall use reasonable efforts to cause their respective Affiliates,
consultants and advisors to hold, in strict confidence all Information
concerning the other furnished to it by the other Party or the other Party's
representatives at any time prior to Closing or pursuant to this Section 7.1
(except to the extent that such Information (i) is or becomes generally
available to the public other than as a result of a disclosure by the receiving
Party in violation of the terms of this Section 5.1, (ii) was within the
possession of the receiving Party prior to it being furnished to the receiving
Party by or on behalf of the other Party pursuant hereto, provided that the
source of such information was not known by the receiving Party at the time of
receipt to be bound by a confidentiality agreement with or other contractual,
legal or fiduciary obligation of confidentiality to the other Party or any other
party with respect to such information, (iii) is or becomes available to the
receiving Party from a source other than the other Party, provided that such
source is not, to the knowledge of the receiving Party at the time of receipt,
bound by a confidentiality agreement with or other contractual, legal or
fiduciary obligation of confidentiality to the other Party or any other party
with respect to such information, or (iv) was or is independently developed by
the receiving Party without utilizing any Information or violating any of the
receiving Party's obligations under this Agreement), and each Party shall not
release or disclose such Information to any other person, except its auditors,
attorneys, financial advisors, bankers and other consultants and advisors,
unless compelled to disclose such Information by judicial or administrative
process or, as advised by its counsel, by other requirements of law; provided,
however, that in the case of disclosure compelled by judicial or administrative
process, the disclosing Party shall notify the non-disclosing Party promptly of
the request or requirement so that the non-disclosing Party may seek an
appropriate protective order or waive compliance with the provisions of this
Section 5.1(d). If, in the absence of a protective order or the receipt of a
waiver hereunder, a Party is, on the advice of counsel, compelled to disclose
any Information by judicial or administrative process, such Party may so
disclose the Information; provided, however, that, at the written request of the
non-disclosing Party, the disclosing Party shall use commercially reasonable
efforts to obtain, at the expense of the non-disclosing Party an order or other
assurance that confidential treatment will be accorded to such portion of the
Information required to be disclosed.

         7.2 DIRECTOR AND OFFICER INDEMNIFICATION. The Buyer shall not take any
action to alter or impair any exculpatory or indemnification provisions, now

                                       13

the Subsidiaries at any time prior to the Closing Date, except for any changes
that may be required to conform with changes in applicable law and any changes
that do not affect the application of such provisions to acts or omissions of
such individuals prior to the Closing Date.

         7.3 FURTHER ASSURANCES. At any time and from time to time after the
Closing, as and when requested by any Party hereto and at such Party's expense,
the other Party shall promptly execute and deliver, or cause to be executed and
delivered, all such documents and instruments and shall take, or cause to be

of the Buyer or the Company. After the thirty (30) day period, Seller shall have
no further liability regarding any representations as to assets. Seller will
indemnify Buyer or the Company for any pre-Closing liabilities which were not
disclosed by Seller and which are discovered by the Company and reported in
writing to Seller, specifically referring to this agreement, within two years
after the Closing. After the two (2) year period, Seller shall have no further
liability regarding any representations as to liabilities. SUCH REPRESENTATIONS
AND WARRANTIES BY THE SELLER CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS
AND WARRANTIES OF THE SELLER TO THE BUYER IN CONNECTION WITH THE TRANSACTIONS
CONTEMPLATED HEREBY, AND THE BUYER UNDERSTANDS, ACKNOWLEDGES AND AGREES THAT ALL
OTHER REPRESENTATIONS AND WARRANTIES OF ANY KIND OR NATURE WHETHER EXPRESS,
IMPLIED OR STATUTORY (INCLUDING, BUT NOT LIMITED TO, ANY RELATING TO THE FUTURE
OR HISTORICAL FINANCIAL CONDITION, RESULTS OF OPERATIONS, ASSETS OR LIABILITIES
