          (e)  Payment of Loan Fee. Bank shall have received from Borrowers

          (g)  Other Documents. Bank shall have received such other documents,
information and items from Borrowers as it shall reasonably request to
effectuate the transactions contemplated hereby.

     6.   Release And Waiver.

          (a)  Each Borrower hereby acknowledges and agrees that: (1) it has no
claim or cause of action against Bank or any parent, subsidiary or affiliate of
Bank, or any of Bank's officers, directors, employees, attorneys or other
representatives or agents (all of which parties other than Bank being,
collectively, "Bank's Agents") in connection with the Loan Documents, the loans
thereunder or the transactions contemplated therein and herein; (2) it has no
offset or defense against any of its respective obligations, indebtedness or
contracts in favor of Bank; and (3) it recognizes that Bank has heretofore
properly performed and satisfied in a timely manner all of its obligations to
and contracts with such Borrower.

          (b)  Although Bank regards its conduct as proper and does not believe
any Borrower to have any claim, cause of action, offset or defense against Bank
or any of Bank's Agents in connection with the Loan Documents, the loans
thereunder or the transactions contemplated therein, Bank wishes and each
Borrower agrees to eliminate any possibility that any past conditions, acts,
omissions, events, circumstances or matters could impair or otherwise affect any
rights, interests, contracts or remedies of Bank. Therefore, each Borrower
unconditionally releases and waives (1) any and all liabilities, indebtedness
and obligations, whether known or unknown, of any kind of Bank or of any of
Bank's Agents to such Borrower, except the obligations remaining to be performed
by Bank as expressly stated in the Loan Agreement, this Second Amendment and the
other Loan Documents executed by Bank; (2) any legal, equitable or other
obligations or duties, whether known or unknown, of Bank or of any of Bank's
Agents to any Borrower (and any rights of such Borrower against Bank) besides
those expressly stated in the Loan Agreement, this Second Amendment and the
other Loan
<PAGE>

Documents; (3) any and all claims under any oral or implied agreement,
obligation or understanding with Bank or any of Bank's Agents, whether known or
unknown, which is different from or in addition to the express terms of the Loan
Agreement, this Second Amendment or any of the other Loan Documents; and (4) all
other claims, causes of action or defenses of any kind whatsoever (if any),
whether known or unknown, which any Borrower might otherwise have against Bank
or any of Bank's Agents, on account of any condition, act, omission, event,
contract, liability, obligation, indebtedness, claim, cause of action, defense,
circumstance or matter of any kind whatsoever which existed, arose or occurred
at any time prior to the execution and delivery of this Second Amendment or
which could arise concurrently with the effectiveness of this Second Amendment.

          (c)  Each Borrower agrees that it understands the meaning and effect
of Section 1542 of the California Civil Code, which provides:

               Section 1542. Certain Claims Not Affected by General
               Release. A general release does not extend to claims that
               the creditor does not know or suspect to exist in his
               favor at the time of executing the release, which if
               known by him must have materially affected his settlement
               with the debtor.

EACH BORROWER AGREES TO ASSUME THE RISK OF ANY AND ALL UNKNOWN, UNANTICIPATED OR
MISUNDERSTOOD DEFENSES, CLAIMS, CAUSES OF ACTION, CONTRACTS, LIABILITIES,
INDEBTEDNESS AND OBLIGATIONS WHICH ARE RELEASED BY THIS FIRST AMENDMENT IN FAVOR
OF BANK AND BANK'S AGENTS, AND EACH BORROWER HEREBY WAIVES AND RELEASES ALL
RIGHTS AND BENEFITS WHICH IT MIGHT OTHERWISE HAVE UNDER THE AFOREMENTIONED
SECTION 1542 OF THE CALIFORNIA CIVIL CODE WITH REGARD TO THE RELEASE OF SUCH
UNKNOWN, UNANTICIPATED OR MISUNDERSTOOD DEFENSES, CLAIMS, CAUSES OF ACTION,
CONTRACTS, LIABILITIES, INDEBTEDNESS AND OBLIGATIONS.  TO THE EXTENT (IF ANY)
WHICH ANY SUCH LAWS MAY BE APPLICABLE, EACH BORROWER WAIVES AND RELEASES (TO THE
MAXIMUM EXTENT PERMITTED BY LAW) ANY RIGHT OR DEFENSE WHICH IT MIGHT OTHERWISE
HAVE UNDER ANY OTHER LAW OF ANY APPLICABLE JURISDICTION WHICH MIGHT LIMIT OR
RESTRICT THE EFFECTIVENESS OR SCOPE OF ANY OF ITS WAIVERS OR RELEASES UNDER THIS
FIRST AMENDMENT.

     7.   Full Force And Effect; Entire Agreement. Except to the extent
expressly provided in this Second Amendment, the terms and conditions of the
Loan Agreement and the other Loan Documents shall remain in full force and
effect. This Second Amendment and the other Loan Documents constitute and
contain the entire agreement of the parties hereto and supersede any and all
prior agreements, negotiations, correspondence, understandings and
communications between the parties, whether written or oral, respecting the
subject matter hereof. The parties hereto further agree that the Loan Documents
comprise the entire agreement of the parties thereto and supersede any and all
prior agreements, negotiations, correspondence, understandings and other
communications between the parties thereto, whether written or oral respecting
the extension of credit by Bank to Borrowers and/or their respective affiliates.

     8.   Counterparts; Effectiveness. This Second Amendment may be executed in
any number of counterparts, each of which when so delivered shall be deemed an
original, but all such counterparts taken together shall constitute but one and
the same instrument. Each such agreement shall become effective upon the
execution of a counterpart hereof or thereof by each of the parties hereto and
telephonic notification that such executed counterparts has been received by
each Borrower and Bank.

     In Witness Whereof, each of the parties hereto has caused this Second
Amendment to be executed and delivered by its duly authorized officer as of the
date first written above.
