                   -----

Purchaser for such period of time, and upon such terms, as Purchaser, in its
sole and absolute discretion, may deem appropriate.

     Section 2.10.  Third Party Consents.  To the extent that Seller's rights
                    --------------------
under any agreement, contract, commitment, lease, or other Purchased Asset may
not be assigned without the Consent of another Person which has not been
obtained, this Agreement shall not constitute an agreement to assign the same if
an attempted assignment would constitute a breach thereof or be unlawful, and
Seller, at its expense, shall use its best efforts to obtain any such required
Consent(s) as promptly as possible.  If any such Consent shall not be obtained
or if any attempted assignment would be ineffective or would impair Purchaser's
rights under the Purchased Asset in question so that Purchaser would not in
effect acquire the benefit of all such rights, Seller, to the maximum extent
permitted by law, shall act after the Closing, as Purchaser's agent in order to
obtain for it the benefits thereunder and shall cooperate, to the maximum extent
permitted by law, with Purchaser in any other reasonable arrangement designed to
provide such benefits to Purchaser.

all Liabilities arising out of any failure or alleged failure to comply with
such laws in respect of the Transaction.

may agree.  Either Party may terminate this Agreement if Closing has not been

incorporated, validly existing and in good standing under the laws of the State

Business as currently conducted.

                                       6
<PAGE>

     Section 4.2.  Authority For Agreement.  Seller has the power and authority
                   -----------------------
to make, execute, deliver and perform this Agreement, the Seller Documents and
to consummate the Transaction.  The execution, delivery and performance of this
Agreement, the Seller Documents and the consummation of the Transaction have
been duly authorized by all necessary action on the part of Seller.  This
Agreement and the Seller Documents constitute the valid and legally binding
obligations of Seller enforceable in accordance with their terms, except as
enforcement thereof may be limited by bankruptcy, insolvency, moratorium or
similar laws affecting creditors' rights and subject to equitable principles.

     Section 4.3.  No Default.  Neither the execution nor delivery of this
                   ----------
Agreement, the Seller Documents, nor the consummation of the Transaction by
Seller will (a) result in a breach or violation by Seller of its organizational
documents, any Contractual Obligation or Legal Requirement; (b) give to any
Person any claim, rights of termination, cancellation or acceleration, in or
with respect to any agreements, contracts or commitments to which Seller is a
party which relate to the Purchased Assets, the Assumed Liabilities or the
Business; or (c) result in the creation or imposition of (or the right or
obligation to create or impose) any Lien upon any of the Purchased Assets
pursuant to the terms of any indenture, mortgage, deed of trust, lease,
agreement or other instrument to which Seller is a party or by which it may be
bound.

     Section 4.4.  Tax Matters.  Seller has timely filed all necessary Tax
                   -----------
Returns that would affect the Purchased Assets, the Assumed Liabilities or the
Business, and all such Tax Returns are complete and correct in all material
respects and accurately reflect all liabilities for Taxes for the related
periods.  No Governmental Authority with which Seller does not file Tax Returns
has alleged in a written or oral communication received by Seller an obligation
on the part of Seller to so file Tax Returns.  Seller has paid or has adequately
provided for, all Taxes payable by, or due from, Seller for all periods ended on
or before the Closing Date, including any and all Taxes required to have been so
withheld or paid in connection with amounts owed or paid to any employee,
contractor or other third party.  No Liens or pending, claims exist for failure
or alleged failure to pay Taxes and there is no basis for any such claim.  No
deficiency or claim or dispute is outstanding, proposed or assessed against
Seller or any property of Seller with respect to any Tax.  No examination or
audit by a Governmental Authority of any Tax Return filed with such Governmental
Authority is in progress nor has Seller received notice that any such
examination or audit is contemplated.  Seller is not a "foreign person" for
purposes of Section 1445 of the Code.

     Section 4.5.  Title.  Except for the Assumed Liabilities, Seller has good
                   -----
title, free and clear of all title defects, objections and Liens of any nature
whatsoever (except as provided in the following sentence) to all of the
Purchased Assets.  Seller has not pre-sold any of the Inventory.  There are no
existing agreements, options, commitments or rights with, of, or to any Person
to acquire the Purchased Assets or rights or any interest therein.

     Section 4.6.  Solvency.  The Purchase Price is reasonably equivalent to the
                   --------
fair market value of the Purchased Assets.  After the Closing, (a) the fair
market value of the remaining assets of Seller will be greater than the amount
that will be required to pay the known Liabilities of Seller as they become due,
and (b) Seller will be able to pay its debts as they mature.

nor has Seller received notice of any (a) unresolved claim or threat that Seller
has breached any term or condition of any of the Assigned Contracts, or (b)
notice of repudiation or denial of the enforceability of any of the Assigned
Contracts.  All Assigned Contracts are in full force and effect and there is no
Default under any such Assigned Contracts.

   ------------
applicable to the Leased Property has been modified or amended in writing in any
material respect.  Except as set forth in Schedule 4.8, none of the Leased
                                          ------------
Property is subject to any sublease, license or other agreement granting to any
Person any right to the use, occupancy or enjoyment thereof.  Seller has not

     (c)  An Indemnified Party will not Consent to the entry of any judgment or
          enter into any settlement with respect to a Third Party Claim without
          the Consent of the Indemnifying Party, which Consent will not be
          withheld unreasonably; and the Indemnifying Party will not Consent to
          the entry of any judgment with respect to a Third Party Claim or enter
          into any settlement which does not include a provision whereby the
          plaintiff or claimant in the Third Party Claim releases the

                                       14

          Indemnified Party from all Liability with respect to the Third Party
          Claim, without the Consent of the Indemnified Party.

     (d)  If an Indemnifying Party does not notify the Indemnified Party within
          fifteen (15) calendar days after the Indemnified Party has given
          notice of a Third Party Claim that the Indemnifying Party is assuming
          the defense of the Third Party Claim, then the Indemnified Party may
          defend against, or enter into any settlement with respect to, the
          Third Party Claim in any manner it may reasonably conclude to be
          appropriate.

     Section 7.5.  Equitable Relief.  Each Party acknowledges that the other
                   ----------------
Party may be irrevocably damaged if the Party fails to perform any of its

injunctive relief to prevent the breach of any of the obligations under this
Agreement and may specifically enforce performance of those obligations.

     Section 7.6.  Other Remedies.  The indemnification provisions set forth in
                   --------------
this Article VII are in addition to, and not in derogation of, any statutory or
common law remedy which a Party may have for a Breach.

if the Party expressly waives that right in a writing delivered to the other
Party.  The waiver by a Party of a right or remedy with respect to a breach of

respect to any subsequent breach, and any failure or delay in exercising any
right under this Agreement will not be construed as a waiver of that right.

agreements and understandings between the Parties and constitutes the entire
