terminate  any  obligation  to extend  any  additional  credit or make any other
financial   accommodation  to  the  Borrower  and/or  may  declare  all  of  the
Obligations to be immediately due and payable. If any Obligation  (including but
not limited to the Note) is a demand  instrument,  the  statement  of a maturity
date, the requirement of periodic interest or the recitation of defaults and the
right of Lender to declare any  Obligation  due and payable shall not constitute
an election by Lender to waive its right to demand payment under a demand at any
time and in any event as Lender in its sole discretion may deem appropriate.  In
the event the  indebtedness  evidenced  hereby is  collected  by or  through  an
attorney,  the holder shall be entitled to recover  reasonable  attorney's  fees

Bank by means of data transmission (telex, telecopier,  terminals,  telephone or
otherwise) at the most recent  address  furnished to the Company by or on behalf
of the  Principal  Bank or by means of direct  telephonic  instructions  from an
Authorized  Representative.  The  Company  agrees  to  promptly  confirm  to the
Principal  Bank in  writing  any  verbal  instructions,  but the  failure of the
Company to confirm such instructions  shall not impair or diminish the Company's
duties  and  obligations  to the Banks  hereunder  arising  on  account  of such
instructions.




         4.  Company's  Covenants.  Except as  otherwise  provided  herein,  the
Company  hereby  agrees that as to each Credit issued  hereunder,  the terms and
provisions set forth on Exhibit B attached hereto shall apply to such Credit and
shall bind the Company with respect to such Credit.

         5. Responsibility. The Banks shall be entitled to rely and act upon
instructions from any Authorized Representative. The Banks shall also be
entitled to rely and act upon the instructions of any person identifying himself
or herself as an Authorized Representative, whether or not such person is in
fact an Authorized Representative, and the Company shall be bound thereby in the
same manner and to the same extent as if such person was actually authorized.
The Company agrees to indemnify and hold the Banks harmless from any and all
claims, damages, losses, liability, costs and expenses (including reasonable
attorneys' fees) which may result from or arise out of or may be incurred by the
Banks, the Remote Correspondent Banks, or any of them, as a result of acceptance
of and reliance on instructions from or on behalf of the Company pursuant to the
provisions of this Agreement.

         6.  Examination  of Documents by Company.  Upon receipt by the Company,
the Company agrees to promptly examine all drafts and documents  presented under
any  credit  and to  notify  the  Principal  Bank  in  writing  of  any  alleged
discrepancies or  irregularities.  Failure of the Company to give such notice to
the  Principal  Bank within a reasonable  time not to exceed five  business days
shall be deemed to be a waiver by the Company (and any Affiliate of the Company)
of any such alleged discrepancies and/or irregularities.

         7. Termination. This Agreement shall continue in effect until such date
of  discontinuance  as may be specified in a written  notice from the Company to
the Principal Bank at the Principal Bank's most recent address  furnished to the
Company;  provided,  however,  that the date so specified  shall be at least ten
(10) days after the receipt of such notice by the Principal  Bank; and provided,
further,   that  notwithstanding  any  discontinuance  or  termination  of  this
Agreement,  this  Agreement  shall  apply  to all  Credits  issued  prior to the
effective date of such  discontinuance or termination and to all obligations and
liabilities  of the Company with respect to such Credits  existing at such date.
Any security  interests granted to the Banks hereunder and under Exhibit B shall
continue  until such time as all  obligations  and  liabilities  of the  Company
hereunder have been satisfied.

         8. Construction and Interpretation. This Agreement (but not the Credits
or Exhibit B) shall be governed by and construed in accordance with the Laws of
the state where the Principal Bank has its principal office. The Credits and
Exhibit B shall be governed by and construed in accordance with the provisions
of Exhibit B.

         9. Delay and Waiver. No delay on the part of the Banks or the Remote
Correspondent Banks in the exercise of any right or remedy shall operate as a
waiver thereof, and no single or partial exercise by the Banks or the Remote
Correspondent Banks of any right or remedy shall preclude other or further
exercise thereof, or the exercise of any other right or remedy. The Banks and
the Remote Correspondent Banks shall not be deemed to have waived any of their
rights hereunder unless they or their duly authorized agent shall have signed an
express waiver thereof in writing. No such waiver shall, unless expressly stated
therein, be effective as to any transaction or event which occurred subsequent
to the date of such waiver, nor as to any continuance of any breach.

         10. Miscellaneous. This Agreement may not be amended or modified except
by a writing signed by the Company,  the Principal Bank and any other Bank which
then has issued a Credit  hereunder  which remains  outstanding.  This Agreement
shall be binding upon the Company and its successors and assigns and shall inure
to the benefit of the Banks and their successors and assigns.
