or setoff all sums owing on the indebtedness against any and all such accounts.

EVENTS OF DEFAULT.  Each of the following shall constitute an Event of Default
under this Agreement:

  Default on Indebtedness.  Failure of Borrower to make any payment when due on
  the Loans.

  Other Defaults.  Failure of Borrower or any Grantor to comply with or to
  perform when due any other term, obligation, covenant or condition contained
  in this Agreement or in any of the Related Documents, or failure of Borrower
  to comply with or to perform any other term, obligation, covenant or condition
  contained in any other agreement between Lender and Borrower.

  under any loan, extension of credit, security agreement, purchase or sales
  agreement, or any other agreement, in favor of any other creditor or person
  that may materially affect any of Borrower's property or Borrower's or any
  Grantor's ability to repay the Loans or perform their respective obligations
  under this Agreement or any of the Related Documents.

  False Statements.   Any warranty, representation or statement made or
  furnished to Lender by or on behalf of Borrower or any Grantor under this

  respect at the time made or furnished, or becomes false or misleading at any

                                       6

  business, the insolvency of Borrower, the appointment of a receiver for any
  part of Borrower's property, any assignment for the benefit of creditors, any
  type of creditor workout, or the commencement of any proceeding under any
  bankruptcy or insolvency laws by or against Borrower.

  Creditor or Forfeiture Proceedings.  Commencement of foreclosure or forfeiture
  proceedings, whether by judicial proceeding, self-help, repossession or any
  other method, by any creditor of Borrower, any creditor of any Grantor against
  any collateral securing the Indebtedness, or by any governmental agency.  This
  includes a garnishment, attachment, or levy on or of any of Borrower's deposit
  accounts with Lender.  However, this Event of Default shall not apply if there
  is a good faith dispute by Borrower or Grantor, as the case may be, as to the
  validity or reasonableness of the claim which is the basis of the creditor or
  forfeiture proceeding, and if Borrower or Grantor gives Lender written notice
  of the creditor or forfeiture proceeding and furnishes reserves or a surety
  bond for the creditor or forfeiture proceeding satisfactory to Lender.

  Events Affecting Guarantor.  Any of the preceding events occurs with respect
  to any Guarantor of any of the Indebtedness or any Guarantor dies or becomes
  incompetent, or revokes or disputes the validity of, or liability under, any
  Guaranty of the Indebtedness.  Lender, at its option, may, but shall not be
  required to, permit the Guarantor's estate to assume unconditionally the
  obligations arising under the guaranty in a manner satisfactory to Lender,
  and, in doing so, cure the Event of Default.

  Change In Ownership.  Any change in ownership of twenty-five percent (25%) or
  more of the common stock of Borrower.

  Adverse Change.  A material adverse change occurs in Borrower's financial
  condition, or Lender believes the prospect of payment or performance of the
  Indebtedness is impaired.

  Right to Cure.  If any default, other than a Default on Indebtedness, is
  curable and if Borrower or Grantor, as the case may be, has not been given a
  notice of a similar default within the preceding twelve (12) months, it may be
  cured (and no Event of Default will have occurred) if Borrower or Grantor, as
  the case may be, after receiving written notice from Lender demanding cure of
  such default: (a) cures the default within fifteen (15) days; or (b) if the
  cure requires more than fifteen (15) days, immediately initiates steps which
  Lender deems in Lender's sole discretion to be sufficient to cure the default
  and thereafter continues and completes all reasonable and necessary steps
  sufficient to produce compliance as soon as reasonably practical.

EFFECT OF AN EVENT OF DEFAULT.  If any Event of Default shall occur, except
where otherwise provided in this Agreement or the Related Documents, all
commitments and obligations of Lender under this Agreement or the Related
Documents or any other agreement immediately will terminate (including any
obligation to make Loan Advances or disbursements), and, at Lender's option, all
Indebtedness immediately will become due and payable, all without notice of any
kind to Borrower, except that in the case of an Event of Default of the type
described in the "Insolvency" subsection above, such acceleration shall be
automatic and not optional.  In addition, Lender shall have all the rights and
remedies provided in the Related Documents or available at law, in equity, or
otherwise.  Except as may be prohibited by applicable law, all of Lender's
rights and remedies shall be cumulative and may be exercised singularly or
concurrently.  Election by Lender to pursue any remedy shall not exclude pursuit
of any other remedy, and an election to make expenditures or to take action to
perform an obligation of Borrower or of any Grantor shall not affect Lender's
right to declare a default and to exercise its rights and remedies.

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of
this Agreement:

  Amendments.  This Agreement, together with any Related Documents, constitutes
  the entire understanding and agreement of the parties as to the matters set
  forth in this Agreement.  No alteration of or amendment to this Agreement
  shall be effective unless given in writing and signed by the party or parties
  sought to be charged or bound by the alteration or amendment.

  Applicable Law.  This Agreement has been delivered to Lender and accepted by
  Lender in the State of California.  If there is a lawsuit, Borrower agrees
  upon Lender's request to submit to the jurisdiction of the courts of San
  Francisco County, the State of California.  Lender and Borrower hereby waive
  the right to any jury trial in any action, proceeding, or counterclaim brought
  by either Lender or Borrower against the other.  (Initial here __/s/___)  This
  Agreement shall be governed by and construed in accordance with the laws of
  the State of California.

  Caption Headings.  Caption headings in this Agreement are for convenience
  purposes only and are not to be used to interpret or define the provisions of
  this Agreement.

  Consent to Loan Participation.  Borrower agrees and consents to Lender's sale
  or transfer, whether now or later, of one or more participation interests in
  the Loans to one or more purchasers, whether related or unrelated to Lender.
  Lender may provide, without any limitation whatsoever, to any one or more
  purchasers, or potential purchasers, any information or knowledge Lender may
  have about Borrower or about any other matter relating to the Loan, and
  Borrower hereby waives any rights to privacy it may have with respect to such
  matters.  Borrower additionally waives any and all notices of sale of
  participation interests, as well as all notices of any repurchase of such
  participation interests.  Borrower also agrees that the purchasers of any such
  participation interests will be considered as the absolute owners of such
  interests in the Loans and will have all the rights granted under the
  participation agreement or agreements governing the sale of such participation
  interests.  Borrower further waives all rights of offset or counterclaim that
  it may have now or later against Lender or against any purchaser of such a
  participation interest and unconditionally agrees that either Lender or such
  purchaser may enforce Borrower's obligation under the Loans irrespective of
  the failure or insolvency of any holder of any interest in the Loans.
  Borrower further agrees that the purchaser of any such participation interests
  may enforce its interests irrespective of any personal claims or defenses that
  Borrower may have against Lender.

  Costs and Expenses.  Borrower agrees to pay upon demand all of Lender's
  expenses, including without limitation attorneys' fees, incurred in connection
  with the preparation, execution, enforcement, modification and collection of
  this Agreement or in connection with the Loans made pursuant to this
  Agreement.  Lender may pay someone else to help collect the Loans and to
  enforce this Agreement, and Borrower will pay that amount.  This includes,
  subject to any limits under applicable law, Lender's attorneys' fees and
  Lenders legal expenses, whether or not there is a lawsuit, including
  attorneys' fees for bankruptcy proceedings (including efforts to modify or
  vacate any automatic stay or injunction), appeals, and any anticipated post-
  judgment collection services.  Borrower also will pay any court costs, in
  addition to all other sums provided by law.

                                       7


  Notices.  All notices required to be given under this Agreement shall be given
  in writing, may be sent by telefacsimile (unless otherwise required by law),
  and shall be effective when actually delivered or when deposited with a
  nationally recognized overnight courier or deposited in the United States
  mail, first class, postage prepaid, addressed to the party to whom the notice
  is to be given at the address shown above.  Any party may change its address
  for notices under this Agreement by giving formal written notice to the other
  parties, specifying that the purpose of the notice is to change the party's
  address.  To the extent permitted by applicable law, it there is more than one
  Borrower, notice to any Borrower will constitute notice to all Borrowers.  For
  notice purposes, Borrower will keep Lender informed at all times of Borrower's
  current address(es).

  Severability.  If a court of competent jurisdiction finds any provision of
  this Agreement to be invalid or unenforceable as to any person or
  circumstance, such finding shall not render that provision invalid or
  unenforceable as to any other persons or circumstances.  If feasible, any such
  offending provision shall be deemed to be modified to be within the limits of
  enforceability or validity; however, if the offending provision cannot be so
  modified, it shall be stricken and all other provisions of this Agreement in
  all other respects shall remain valid and enforceable.

  Subsidiaries and Affiliates of Borrower.  To the extent the context of any
  provisions of this Agreement makes it appropriate, including without
  limitation any representation, warranty or covenant, the word "Borrower" as
  used herein shall include all subsidiaries and affiliates of Borrower.
  Notwithstanding the foregoing however, under no circumstances shall this
  Agreement be construed to require Lender to make any Loan or other financial
  accommodation to any subsidiary or affiliate of Borrower.

  Successors and Assigns.  All covenants and agreements contained by or on
  behalf of Borrower shall bind its successors and assigns and shall inure to
  the benefit of Lender, its successors and assigns.  Borrower shall not,
  however, have the right to assign its rights under this Agreement or any
  interest therein, without the prior written consent of Lender.

  Survival.  All warranties, representations, and covenants made by Borrower in
  this Agreement or in any certificate or other instrument delivered by Borrower
  to Lender under this Agreement shall be considered to have been relied upon by
  Lender and will survive the making of the Loan and delivery to Lender of the
  Related Documents, regardless of any investigation made by Lender or on
  Lender's behalf.

  Time is of the Essence.  Time is of the essence in the performance of this
  Agreement.

  Waiver.  Lender shall not be deemed to have waived any rights under this
  Agreement unless such waiver is given in writing and signed by Lender.  No
  delay or omission on the part of Lender in exercising any right shall operate
  as a waiver of such right or any other right.  A waiver by Lender of a
  provision of this Agreement shall not prejudice or constitute a waiver of
  Lender's right otherwise to demand strict compliance with that provision or
  any other provision of this Agreement.  No prior waiver by Lender, nor any
  course of dealing between Lender and Borrower, or between Lender and any
  Grantor, shall constitute a waiver of any of Lender's rights or of any
  obligations of Borrower or of any Grantor as to any future transactions.
  Whenever the consent of Lender is required under this Agreement, the granting
  of such consent by Lender in any instance shall not constitute continuing
  consent in subsequent instances where such consent is required, and in all
  cases such consent may be granted or withheld in the sole discretion of
  Lender.
