then the Bank shall have the right in its sole discretion to determine, which
rights, security, liens, security interests or remedies the Bank shall at any
time pursue, relinquish, subordinate, modify or take any other action with
respect thereto, without in any way modifying or affecting any such rights or
any of the Bank's rights hereunder.

the Bank. The Company and the Bank each hereby severally acknowledge that there
are no representations, warranties, covenants, undertakings or agreements by the
parties hereto as to this Agreement except as specifically provided herein. The
Bank shall have no obligation to sell or otherwise realize upon the Collateral

the Bank's failure to realize upon the Collateral.

         7.2 Choice of Law, Construction. This Agreement shall be construed in
             ---------------------------

illegal under any law, all other provisions shall remain in full force and
effect.

         7.3 Consent to Jurisdiction. (a) The Company hereby irrevocably submits
             -----------------------

relating to this Agreement and the Company hereby irrevocably agrees that all
claims in respect of such action or proceeding may be heard and determined in
any such court and irrevocably waives any objection it may now or hereafter have
as to the venue of any such action or proceeding brought in such a court or the
fact that such court is an inconvenient forum.

         (b) The Company irrevocably and unconditionally consents to the service
of process in any such action or proceeding in any of the aforesaid courts by
the mailing of copies of such process to it, by certified or registered mail in
accordance with the terms of Section 7.4 herein.


<PAGE>


         (c) The Company agrees that nothing herein shall affect the Bank's
right to effect service of process in any other manner permitted by law and the

against the Company in any other court or jurisdiction in accordance with
applicable law.

         7.4 Notices. All notices, requests and demands to or upon the

         7.5 Waivers. The Company expressly waives notice of non-payment or
             -------
protest, demand, or presentment, in relation to the Obligations or the
Collateral. No delay or omission of the Bank in exercising or enforcing any of
its rights, powers, privileges, options or remedies under this Agreement or any
other agreement or promissory note between the Bank and the Company shall
constitute a waiver thereof, and no waiver by the Bank of any Event of Default
by the Company shall operate as a waiver of any other Event of Default. Except
for the terms and provisions of any promissory notes or other security
agreements now existing or hereafter executed and delivered to the Bank by the
Company (which terms and provisions are specifically deemed to be in addition to
and not in derogation of the terms and provisions hereof), this Agreement
constitutes the entire understanding between the Company and the Bank with
respect to the subject matter hereof and supersedes all prior written or oral
communications or understandings. No term or provision of this Agreement shall
be waived, altered or modified except in writing signed by the parties hereto.

not alternative or exclusive of any rights or remedies provided by law and may
be exercised by the Bank at such time or times and in such order as the Bank, in
its sole discretion, may determine and are for the sole benefit of the Bank and
the exercise or failure to


<PAGE>


exercise such shall not result in liability to the Company or others except in
the event of willful misconduct or gross negligence by the Bank, and in no event
shall the Bank be liable for more than it actually receives as a result of the
exercise or failure to exercise such right and remedies. The Bank shall not be
liable for any failure by it to comply with any recording, rerecording, filing,
refiling or other legal requirement necessary to establish or maintain the
validity, priority or enforceability of, or the Bank's right in and to the
Collateral, or any part thereof.

         7.6 Successors and Survival. This Agreement shall remain in full force
             -----------------------
and effect until terminated as to future transactions by written agreement of
the parties. The Company may not transfer or assign any of its rights, interest
or obligations hereunder without the prior written consent of the Bank. This
Agreement shall be binding upon the Company and shall inure to the benefit of
the Bank and its successors and assigns and to the permitted successors and
assigns of the Company. All representations, warranties and covenants contained
herein or in any other agreement between the Bank and the Company shall survive
the execution hereof and thereof and the granting of loans or advances pursuant
hereto or thereto.

         7.7 Waiver of Counterclaim; Setoff. In any litigation initiated by the
             ------------------------------
Bank whether pursuant hereto or otherwise in which the Company and the Bank are
adverse parties the Company waives the right to interpose any set-off or
counterclaim of any nature or description against the Bank.

         7.8 Captions. The headings of the Section in this Agreement are for
             --------

interpretation.

         7.9 Severability. If any provision of this Agreement shall be or become
             ------------
illegal or unenforceable in whole or in part for any reason whatsoever, the
