required of Borrower hereunder in order to preserve, protect, maintain or

LIABILITIES.
8.1 No Impairment of Obligations. Borrower assumes all responsibility and
liability arising from or relating to the use, license, sale or other
disposition of the Collateral. The Obligations shall not be affected by any
failure of the Lenders to take any steps to perfect the Lenders' liens or to
collect or realize upon the Collateral, nor shall loss of or damage to the
Collateral release Borrower from any of the Obligations. 8.2 Borrower Remains
Liable. Anything herein to the contrary notwithstanding, Borrower shall remain
liable under each of its contracts and each of its licenses to observe and
perform all the conditions and obligations to be observed and performed by it
thereunder. The Lenders shall not have any obligation or liability under any
contract or license by reason of or arising out of this Agreement or the
granting herein of a lien thereon or the receipt by the Lenders of any payment
relating to any contract or license pursuant hereto. The Lenders shall not be
required or obligated in any manner to perform or fulfill any of the obligations
of Borrower under or pursuant to any contract or license, or to make any
payment, or to make any inquiry as to the nature or the sufficiency of any
payment received by it or the sufficiency of any performance by any party under
any contract or license, or to present or file any claims, or to take any action
to collect or enforce any performance or the payment of any amounts which may
have been assigned to it or to which it may be entitled at any time or times. 9.
INDEMNIFICATION.

         In any suit, proceeding or action brought by the Lenders relating to

Collateral for any sum owing with respect thereto or to enforce any rights or
claims with respect thereto, Borrower will save, indemnify and keep the Lenders
harmless from and against all expense (including reasonable attorneys' fees and
expenses), loss or damage suffered by reason of any defense, setoff,
counterclaim, recoupment or reduction of liability whatsoever of the Account
Debtor or other individual or entity obligated on the Collateral, arising out of
a breach by Borrower of any obligation thereunder or arising out of any other
agreement, indebtedness or liability at any time owing to, or in favor of, such
obligor or its successors from Borrower, except in the case of the Lenders, to
the extent such expense, loss, or damage is attributable solely to the gross
negligence or willful misconduct of the Lenders as finally determined by a court
of competent jurisdiction. All such obligations of Borrower shall be and remain
enforceable against and only against Borrower and shall not be enforceable
against the Lenders.
10.      MISCELLANEOUS.
10.1 Additional Acts. Borrower shall, upon request, execute and deliver such
further instruments and documents and do such further acts and things as may be
reasonably required to provide to the Lenders the evidence of and security for
the Obligations as well as the perfection of the Lenders' security interest in
the Collateral and its priority against all other parties.
10.2 Amendment: Waiver; Approval. This Agreement shall not be amended, modified
or supplemented without the written agreement of Borrower and the Lenders at the
time of such amendment, modification or supplement. No waiver of any provision
of this Agreement shall be effective unless set forth in writing signed by the
party making such waiver, and any such waiver shall be effective only to the
extent therein set forth. Failure by the Lenders to insist upon full and prompt
performance of any provisions of this Agreement, or to take action upon the
occurrence of any Event of Default, shall not constitute a waiver of any rights
of the Lenders, and the Lenders may at any time thereafter exercise all
available rights and remedies with respect to such Event of Default. Receipt by
the Lenders of any instrument or document shall not constitute or be deemed to
be an approval thereof.
10.3 Entire Agreement. This Agreement, the Debentures and related documents
constitute the entire agreement and understanding among the Borrower and the
Lenders, and supersede any prior agreement and understanding relating to the
subject matter of this Agreement; provided, however, that notwithstanding the
foregoing, this Agreement shall supersede any previous security agreement, or
security interest or pledge, given by Borrower to secure any or all of the
Obligations.
10.4 Notice. Any notice which any party hereto gives to any other party
hereunder shall be in accordance with the provisions of the Debenture relating
thereto. 10.5 Benefit; Assignment. The rights, powers and remedies of the
Lenders and Borrower under this Agreement shall inure to their respective
benefits and to the benefit of their respective successors and permitted
assigns. The rights and obligations of either Borrower or the Lenders under this

null and void without prior written approval of the other party. 10.6 Governing
Law. This Agreement shall be governed by and construed in accordance with the
laws of the State of California, as applied to agreements among residents made
and to be performed entirely within the State of California.
10.7 Headings. The titles and headings of the articles, sections and paragraphs
of this Agreement have been inserted as a matter of convenience of reference
only and shall not control or affect the meaning or construction of any of the
terms or provisions of this Agreement.
10.8 No Partnership or Joint Venture. The Lenders, by executing and performing
this Agreement (or any of the loan documents), shall not become a partner or
joint venturer with Borrower or any of its respective associates or affiliates
and all inspections herein provided for are for the sole benefit of the Lenders.
10.9 Time is of the Essence. Time is of the essence for the payment of all
amounts due the Lenders under the loan documents and performance and observance
by Borrower of each covenant, agreement, provision and term of the loan
documents.
10.10 Invalid Provisions. In the event any one or more of the provisions
contained in this Agreement or in any of the other loan documents shall for any
reason be held to be invalid, illegal or unenforceable in any respect by a court
of competent jurisdiction, such invalidity, illegality or unenforceability shall
not affect any other provision of this Agreement or any other Loan Document, and
this Agreement and the other Loan Document shall be construed as if such
invalid, illegal or unenforceable provision had never been in the Loan
documents. 10.11 Acts Prohibited Under Law. Notwithstanding anything herein
contained to the contrary, the Lenders will not be required to make any
disbursement or perform any other act under this Agreement if, as a result
thereof, the Lenders will violate any law, statute, ordinance, rule, regulation
or judicial decision applicable thereto. The Lenders shall use their reasonable
efforts to promptly notify Borrower of the Lenders' inability to make such
disbursement or perform such act due to such violation.
10.12 Counterparts. This Agreement and the other Loan documents may be executed
in counterparts, and all said counterparts when taken together shall constitute
one and the same Agreement. 10.13 No Third Party Beneficiary. This Agreement and
the other Loan documents are only for the benefit of the parties hereto and

shall be entitled to rely on any matter set forth herein or therein or shall
gain any rights herein whether by subrogation or otherwise without the prior
written consent of such parties.
