shall assume any and all liabilities, commitments and obligations of Nicolet of
any nature, kind and description except for the Excluded Liabilities (the
"Liabilities"). "Excluded Liabilities" means all liabilities, commitments and
obligations of Nicolet or any of its subsidiaries that result from any third

transfer and conveyance and take such other action as Optek reasonably may
request effectively to assign and transfer to Optek any of the Assets. At the
request of Nicolet at any time on or after the date hereof, Optek will execute
and deliver such further instruments of assumption and take such other action as
Nicolet may reasonably request effectively to assume the Liabilities.

         4. Regarding Certain Consents. Nothing in this Agreement shall be
construed as an attempt to assign any contract, agreement, permit, franchise, or
claim included in the Assets that is, by its term or in law, nonassignable
without the consent of the other party or parties thereto, unless such consent
shall have been given, or as to which all the remedies for the enforcement
thereof enjoyed by Nicolet would not, as a matter of law, pass to Optek as an
incident of the assignments provided for by this Agreement. In order, however,
to provide Optek the full realization and value of every contract, agreement,
permit, franchise and claim of the character described in the preceding
sentence, Nicolet, on and after the date hereof by itself or by its agents,
shall, at the request and expense and under the direction of Optek, in the name
of Nicolet or otherwise as Optek shall specify and as shall be permitted by law,
take all such reasonable action (including without limitation the appointment of
Optek as an attorney-in-fact for Nicolet) and do or cause to be done all such
things as shall in the opinion of Optek be necessary or proper (a) to assure
that the rights and obligations of Nicolet under such contracts, agreements,
permits, franchises, and claims shall be preserved for the benefit of Optek and
(b) to facilitate receipt of the consideration to be received by Nicolet in and
under every such contract, agreement, permit, franchise, and claim, which
consideration Nicolet shall hold for the benefit of, and upon request of Optek
shall deliver to, Optek.

         5.       Nicolet's Representations and Warranties. Nicolet represents
                  and warrants that:

                  (a) Organization and Standing. Nicolet is a corporation duly
         organized, validly existing and in good standing under the laws of the
         State of Wisconsin.

                  (b) Approval of Transactions. Nicolet has obtained all
         necessary corporate authorizations and approvals, and has taken all
         actions required for the execution and delivery of this Agreement and
         the consummation of the transactions contemplated hereby.

                  (c) Title to the Assets. Nicolet is the true and lawful owner
         of, and has good and marketable title to, the Assets free and clear of
         all liens, mortgages, leases, conditional sales agreements, title
         retention agreements, or any other encumbrance. Upon consummation of
         the transfer of the Assets by Nicolet to Optek, Optek will be the
         lawful owner of, and have marketable title to, the Assets, free and
         clear of all liens, mortgages, or other encumbrances.

                  (d) No Litigation. Nicolet is not engaged in, or to the
         knowledge of Nicolet's management, threatened with any material legal
         action or other proceeding before any court, administrative agency,
         governmental department or arbitrator.

                  (e) Compliance with Contracts. Nicolet is in compliance in all
         material respects with all unwaived terms and provisions of all
         material contracts, commitments and engagements entered into prior to
         or on the date hereof; and the same are in full force and effect and
         constitute legal, valid and binding obligations of the respective
         parties thereto, enforceable in accordance with their terms except as
         limited by bankruptcy, insolvency, reorganization, moratorium or
         similar laws relating to or affecting generally the enforcement of
         creditors' rights, and have not been assigned or encumbered by Nicolet.
         Nicolet has performed, in all material respects, obligations required
         to be performed under all such material contracts, commitments and
         engagements to date and is not in default in any material respect under
         any of said contracts, commitments and engagements.

                  (f) No Conflict. Neither the execution nor delivery of this
         Agreement, nor the consummation of the transactions herein
         contemplated, nor the fulfillment of or compliance with the terms and
         provisions hereof will, to the best of Nicolet's knowledge, (1) violate
         any current provisions of law, administrative regulation, or court
         decree applicable to Nicolet or (2) conflict with or result in a breach
         of any of the terms, conditions or provisions of or constitute default
         under any agreement or instrument to which Nicolet is a party or by
         which it is bound.

         6.       Optek's Representations and Warranties.

                  (a) Organization and Standing. Optek is a corporation duly
         organized, validly existing and in good standing under the laws of the
         State of Delaware.

                  (b) Approval of Transactions. Optek has obtained all necessary
         corporate authorizations and approvals, and has taken all actions
         required for the execution and delivery of this Agreement and the
         consummation of the transactions contemplated hereby.

                  (c) Issuance of Shares. The issuance of the Shares has been
duly authorized by all necessary corporate action, and the Shares, when issued
pursuant to the terms of this Agreement, will be fully paid, non-assessable and
not subject to any pre-emptive rights.

         7.       Indemnification by Nicolet.

                  (a) Nicolet agrees to indemnify and hold harmless Optek from
any and all damages, losses, liabilities, costs and expenses (including, without
limitation, settlement costs and any reasonable legal, accounting or other
expenses for investigating or defending any actions or threatened actions)
incurred by Optek as a result of (i) the Excluded Liabilities or (ii) the
inaccuracy of any representation or warranty contained in Section 5 hereof.

                  (b) Whenever any claim shall arise for indemnification
hereunder, Optek shall promptly notify Nicolet of the claim and, when known, the
facts constituting the basis for such claim. In the event of any such claim for
indemnification hereunder resulting from or in connection with any claim or
legal proceedings by a third party, the notice to Nicolet shall specify, if
known, the amount or an estimate of the amount of the liability arising
therefrom. Optek shall not settle or compromise any claim by a third party for
which Optek is entitled to indemnification hereunder without the prior consent
of Nicolet, unless suit shall have been instituted against Optek and Nicolet
shall not have taken control of such suit after notification thereof as provided
in Section 7(c) of this Agreement.

                  (c) In connection with any claim giving rise to indemnity
hereunder resulting from or arising out of any claim or legal proceeding by a
person who is not a party to this Agreement, Nicolet at its sole cost and
expense may, upon notice to Optek, assume the defense of any such claim or legal
proceeding if it acknowledges to Optek its obligations to indemnify Optek with
respect to all elements of such claim. Optek shall be entitled to participate in
(but not control) the defense of any such action, with its counsel and at its
own expense. If Nicolet does not assume the defense of any such claim or
litigation resulting therefrom within 30 days after the date Nicolet is notified
of such claim pursuant to Paragraph 7(b) hereof, (i) Optek may defend against
such claim or litigation, after giving notice of the same to Nicolet, on such
terms as are appropriate in Optek's reasonable judgment, and (ii) Nicolet shall
be entitled to participate in (but not control) the defense of such action, with
its counsel and at its own expense.

         8. Transfer and Sales Tax. Notwithstanding any provisions of law to the
contrary, Nicolet shall be responsible for and shall pay (a) all sales and
transfer taxes, and (b) all governmental charges, if any, upon the sale or
transfer of any of the Assets.

         9. Effective Date. The transfer of the Assets shall be deemed to be
effective as of the close of business on the date first above written, for all
