information with respect to the Company, (b) in the event that the Sellers or
any such agent, representative, Affiliate, employee, officer or director becomes
legally compelled to disclose any such information, provide the Purchaser with
prompt written notice of such requirement so that the Purchaser or the Company
may seek a protective order or other remedy or waive compliance with this

                                  -------- -------
Intellectual Property, specific information shall not be deemed to be within the
foregoing exception merely because it is embraced in general disclosures in the
public domain.  In addition, with respect to Intellectual Property, any
combination of features shall not be deemed to be within the foregoing exception
merely because the individual features are in the public domain unless the
combination itself and its principle of operation are in the public domain.  The

obligations under this Section 5.03 are inadequate and that in addition thereto
the Purchaser shall be entitled to seek equitable relief, including injunction
and specific performance, in the event of any such breach.

making any representation or warranty of the Sellers in this Agreement untrue or
incorrect in any respect and (b) all other material developments affecting the
assets, Liabilities, business, financial condition, operations, results of
operations, customer or supplier relations, employee relations, projections or
prospects of the Company.

          SECTION 5.05. No Solicitation or Negotiation. Each Seller agrees that
                        ------------------------------

the termination of this Agreement, none of the Sellers, the Company, or any of
their respective Affiliates, officers, directors, representatives or agents will

offers from any Person (A) relating to any acquisition or purchase of all or any
portion of the capital stock of the Company or assets of the Company (other than

negotiations and other communications regarding, or furnish to any other Person
any information with respect to, or otherwise cooperate in any way, assist or
participate in, facilitate or encourage any effort or attempt by any other

such proposal or offer, or any inquiry or other contact with any Person with
respect thereto, is made and shall, in any such notice to the Purchaser,
indicate in reasonable detail the identity of the Person making such proposal,
offer, inquiry or contact and the terms and conditions of such proposal, offer,
inquiry or other contact. The Sellers agrees not to, and to cause the Company,
not to, without the prior written consent of the Purchaser, release any Person
from, or waive any provision of, any confidentiality or standstill agreement to

          SECTION 5.06. Further Action. Each of the parties hereto shall use all
                        --------------
reasonable efforts to take, or cause to be taken, all appropriate action, do or
cause to be done all things necessary, proper or advisable under applicable Law,
and execute and deliver such documents and other papers, as may be required to

     Purchaser, seeking to restrain or materially and adversely alter the
     transactions contemplated by this Agreement which, in the reasonable, good
     faith determination of the Sellers, is likely to render it impossible or
     unlawful to consummate such transactions; provided, however, that the
                                               --------  -------

     which could have a Material Adverse Effect or otherwise render inadvisable,
     in the sole and absolute discretion of the Purchaser, the consummation of
     the transactions contemplated by this Agreement; provided, however, that
                                                      --------  -------

claim is made by the Purchaser for the breach of any representation or warranty
of the Sellers contained herein, which claim arises out of allegations of
personal injury or property damage suffered by any third party on or prior to
the Closing Date or attributable to products or Inventory sold or shipped, or
activities or omissions that occur, on or prior to the Closing Date, such
representations and warranties shall, for purposes of such claim by the
Purchaser, survive until thirty calendar days after the expiration of the

time by or on behalf of the Purchaser. If written notice of a claim has been
given prior to the expiration of the applicable representations and warranties

any and all Liabilities, losses, damages, claims, costs and expenses, interest,
awards, judgments and penalties (including, without limitation, attorneys' and
consultants' fees and expenses) actually suffered or incurred by them
(including, without limitation, any Action brought or otherwise initiated by any
of them) (hereinafter a "Loss"), arising out of or resulting from:
                         ----
<PAGE>

                                       27

          (i) the breach of any representation or warranty made by each Seller
     contained in the Acquisition Documents; or

          (ii) the breach of any covenant or agreement by each Seller contained
     in the Acquisition Documents; or

          (iii)  Liabilities of the Company not reflected on the Reference
     Balance Sheet, whether arising before or after the Closing Date, arising
     from or relating to the ownership or actions or inactions of the Sellers or
     the Company prior to the Closing; or

          (iv) any and all Losses suffered or incurred by the Purchaser or the
     Company by reason of or in connection with any claim or cause of action of
     any third party to the extent arising out of any action, inaction, event,
     condition, liability or obligation of each Seller occurring or existing
     prior to the Closing; or

          (v) any and all Taxes imposed upon the Company relating to the
     operation of the Company prior to the Closing Date.

To the extent that the Sellers's undertakings set forth in this Section 7.02 may
be unenforceable, the Sellers shall contribute the maximum amount that it is
permitted to contribute under applicable Law to the payment and satisfaction of
all Losses incurred by the Purchaser, the Company.

          (b) An Indemnified Party shall give each Seller notice of any matter
which an Indemnified Party has determined has given or could give rise to a
right of indemnification under this Agreement, within 60 days of such
determination, stating the amount of the Loss, if known, and method of
computation thereof, and containing a reference to the provisions of this
Agreement in respect of which such right of indemnification is claimed or
arises.  The obligations and Liabilities of each Seller under this Article VII
with respect to Losses arising from claims of any third party which are subject
to the indemnification provided for in this Article VII ("Third Party Claims")
                                                          ------------------
shall be governed by and contingent upon the following additional terms and
conditions:  if an Indemnified Party shall receive notice of any Third Party
Claim, the Indemnified Party shall give each Seller notice of such Third Party
Claim within 30 days of the receipt by the Indemnified Party of such notice;
provided, however, that the failure to provide such notice shall not release any
--------  -------
Seller from any of its obligations under this Article VII except to the extent
that such Seller is materially prejudiced by such failure and shall not relieve
any Seller from any other obligation or Liability that it may have to any
Indemnified Party otherwise than under this Article VII.  If a Seller
acknowledges in writing its obligation to indemnify the Indemnified Party
hereunder against any Losses that may result from such Third Party Claim, then
the Sellers shall be entitled to assume and control the defense of such Third
Party Claim at its expense and through counsel of its choice if it gives notice
of its intention to do so to the Indemnified Party within five days of the
receipt of such notice from the Indemnified Party; provided, however, that if
                                                   --------  -------
there exists or is reasonably likely to exist a conflict of interest that would
make it inappropriate in the judgment of the Indemnified Party in its sole and
absolute discretion, for the same counsel to represent both the Indemnified
Party and
<PAGE>

                                       28

the Sellers, then the Indemnified Party shall be entitled to retain its own
counsel, in each jurisdiction for which the Indemnified Party determines counsel
is required, at the expense of the Sellers. In the event that the Sellers
exercise the right to undertake any such defense against any such Third Party
Claim as provided above, the Indemnified Party shall cooperate with the Sellers
in such defense and make available to the Sellers, at the Sellers' expense, all
witnesses, pertinent records, materials and information in the Indemnified
Party's possession or under the Indemnified Party's control relating thereto as
is reasonably required by the Sellers. Similarly, in the event the Indemnified
Party is, directly or indirectly, conducting the defense against any such Third
Party Claim, the Sellers shall cooperate with the Indemnified Party in such
defense and make available to the Indemnified Party, at the Sellers' expense,
all such witnesses, records, materials and information in the Sellers'
possession or under the Sellers' control relating thereto as is reasonably
required by the Indemnified Party. No such Third Party Claim may be settled by
the Sellers without the prior written consent of the Indemnified Party.

          SECTION 7.03. Limits on Indemnification. Notwithstanding anything to
                        -------------------------
the contrary contained in this Agreement, the maximum amount of indemnifiable
Losses which may be recovered from a Seller arising out of or resulting from the
causes enumerated in Section 7.02 shall be an amount equal to the Purchase Price
received by such Seller.

     bankrupt or insolvent, or seeking liquidation, winding up or
     reorganization, arrangement, adjustment, protection, relief or composition
     of its debts under any Law relating to bankruptcy, insolvency or
     reorganization

          (b) by either the Purchaser or the holders of a majority of the Shares
     in the event that any Governmental Authority shall have issued an order,

     such order, decree, ruling or other action shall have become final and
     nonappealable

party, (b) waive any inaccuracies in the representations and warranties of the

of any subsequent breach or a subsequent waiver of the same term or condition,
or a waiver of any other term or condition, of this Agreement. The failure of
any party to assert any of its rights hereunder shall not constitute a waiver of
any of such rights.

          SECTION 9.12. Specific Performance. The parties hereto agree that
                        --------------------
