     SECTION 1.1.   LINE OF CREDIT.

     (a) Line of Credit.  Subject to the terms and conditions of this Agreement,
         --------------
Bank hereby agrees to make advances to Borrower from time to time (the "Line of
Credit"), the proceeds of which up to a maximum outstanding principal balance of
$6,000,000.00 shall be used to finance working capital requirements (the
"Working Capital Advances", which shall be available until September 3, 2001),
and which up to a maximum outstanding principal balance of $3,500,000.00 (less
the amount of Lease Obligations) shall be used for equipment purchases
("Equipment Advances", which shall be available until September 3, 2000),
provided, however, that the aggregate outstanding principal balance of Working
- -----------------
Capital Advances and Equipment Advances shall not at any time exceed
$8,500,000.00.  Borrower's obligation to repay Working Capital Advances and
Equipment Advances shall be evidenced by a promissory note substantially in the
form of Exhibit A attached hereto ("Line of Credit Note"), all terms of which
are incorporated herein by this reference. The term "Lease Obligations" means
                                                     -----------------
the aggregate amount of all lease obligations under leases entered into between
Bank's equipment leasing affiliate or division as lessor and Borrower as lessee
during the period when Equipment Advances are available.



     (b) Borrowing and Repayment.  Borrower may from time to time during the
         -----------------------
term of the Line of Credit with respect to Working Capital Advances borrow,
partially or wholly repay its outstanding borrowings, and reborrow, and, with
respect to Equipment Advances, borrow, partially or wholly repay its outstanding
borrowings, but not reborrow, subject to all of the limitations, terms and
conditions contained herein or in the Line of Credit Note; provided however,
that the total outstanding borrowings under the Line of Credit shall not at any
time exceed the maximum principal amount available thereunder, as set forth
above. As of and after September 3, 2000, (i) no new Equipment Advances shall be
available, and (ii) the availability for Working Capital Advances shall be
limited to the lesser of (I) $6,000,000.00, or (II) an amount equal to
$8,500,000.00 less the outstanding principal balance of Equipment Advances from
time to time. Repayments of principal received by Bank shall be applied, prior
to September 3, 2000 (unless Bank receives written instructions to the contrary
prior to each payment), first to outstanding Working Capital Advances and then
to outstanding Equipment Advances, and after September 3, 2000, first to the
scheduled installment of the Equipment Advances if such an installment is then
due and payable, second to outstanding Working Capital Advances and then as a
prepayment of Equipment Advances (subject to the prepayment provisions set forth
in the Line of Credit Note).

     (c) Advances.  Each request for an Equipment Advance shall be in writing,
         --------
shall specify the amount and date of the requested advance and shall be
accompanied by an invoice or appraisal (as required below) in form and content
acceptable to Bank. The principal amount of each Equipment Advance shall not

is new or has been acquired within 90 days preceding the date of the requested
advance) as evidenced by invoice delivered to Bank, or 80% of the value of the
applicable equipment (if such equipment is used or has been acquired more than
90 days prior to the date of the requested advance) as evidenced by appraisal
delivered to Bank. Working capital advances shall be available in the manner set
forth in the Line of Credit Note. Bank is hereby authorized to note the original
principal amount of and any payments made on Working capital Advances and
equipment Advances on Bank's books and records (either manually or by electronic
entry) and/or on any schedule attached to this Agreement or to the Line of
Credit Note, which notations shall be prima facie evidence of the accuracy of
the information noted.

          --------

there be insufficient funds in any such demand deposit account to pay all such
sums when due, the full amount of such deficiency shall be immediately due and
payable by Borrower.

     SECTION 1.4.  COLLATERAL.

     As security for all indebtedness of Borrower to Bank subject hereto,
Borrower hereby grants to Bank, and shall cause the other Borrowers to grant to
Bank, security interests of first priority in all such Borrower's accounts

     SECTION 7.1.   NO WAIVER.  No delay, failure or discontinuance of Bank in

     SECTION 7.4.  SUCCESSORS, ASSIGNMENT.  This Agreement shall be binding upon
and inure to the benefit of the heirs, executors, administrators, legal

or grant participations in all or any part of, or any interest in, Bank's rights
and benefits under each of the Loan Documents.  In connection therewith, Bank
may disclose all documents and information which Bank now has or may hereafter

     SECTION 7.5.  ENTIRE AGREEMENT; AMENDMENT.  This Agreement and the other
Loan Documents constitute the entire agreement between Borrower and Bank with

prior negotiations, communications, discussions and correspondence concerning

writing signed by each party hereto.

     SECTION 7.6.  NO THIRD PARTY BENEFICIARIES.  This Agreement is made and

     SECTION 7.7.  TIME.  Time is of the essence of each and every provision of
this Agreement and each other of the Loan Documents.

     SECTION 7.8.  SEVERABILITY OF PROVISIONS.  If any provision of this
Agreement shall be prohibited by or invalid under applicable law, such provision
shall be ineffective only to the extent of such prohibition or invalidity
without invalidating the remainder of such provision or any remaining provisions
of this Agreement.

     SECTION 7.9.  COUNTERPARTS.  This Agreement may be executed in any number
of counterparts, each of which when executed and delivered shall be deemed to be
an original, and all of which when taken together shall constitute one and the
same Agreement.

     SECTION 7.10. GOVERNING LAW.  This Agreement shall be governed by and
construed in accordance with the laws of the State of California.

     SECTION 7.11 JOINT AND SEVERAL LIABILITY.

     (a) Each Borrower has determined and represents to Bank that it is in its
best interests and in pursuance of its legitimate business purposes to induce
Bank to extend credit pursuant to this Agreement.  Each Borrower acknowledges
and represents that its business is related to the business of the other
Borrower, the availability of the commitments provided for herein benefits each
Borrower, and advances made hereunder will inure to the benefit of Borrowers,
individually and as a group.

     (b) Each Borrower has determined and represents to Bank that it has, and
after giving effect to the transactions

                                      -15-


contemplated by this Agreement will have, assets having a fair saleable value in
excess of its debts, after giving effect to any rights of contribution or
subrogation which may ultimately be available to such Borrower, and each
Borrower has, and will have, access to adequate capital for the conduct of its
business and the ability to pay its debts as such debts mature.

     (c) Each Borrower agrees that it is jointly and severally liable to Bank
for, and each Borrower agrees to pay to Bank when due the full amount of, all
indebtedness of Borrowers to Bank arising under or in connection with this
Agreement, including without limitation all advances disbursed to any or all
Borrowers under the Line of Credit, all interest which accrues thereon and all
fees, costs and expenses chargeable to Borrowers hereunder.  Each Borrower
waives any right to require Bank to (1) proceed against any person, including
any other Borrower; (2) proceed against or exhaust any security hold from any
Borrower or any other person, or (3) disclose any information about any
Borrower.  Each Borrower waives any defense against its liability to Bank
hereunder based upon (1) any defense of any other Borrower, (2) the cessation or
limitation from any cause of any indebtedness of any other Borrower to Bank, (3)
the lack of authority of any officer, director, agent or other person acting or
purporting to act on behalf of any other Borrower or Guarantor, (4) the release
of any security for any indebtedness of any Borrower to Bank, (5) the
application of payments received by Bank from any other Borrower to indebtedness
of such Borrower to Bank unrelated to the Line of Credit, (6) the release of any
other Borrower of any liability to Bank, (7) the compromise or modification with
any other Borrower of Bank's claims against such Borrower or of such Borrower's
indebtedness to Bank, (8) any breach by any other Borrower of any agreement
herein or in the other Loan Documents, (9) the invalidity, unenforceability or
illegality of this Agreement or any of other Loan Documents as to any other
Borrower, or (10) any election of remedies by Bank which adversely affects,
impairs or destroys a Borrower's subrogation rights or rights to proceed against
any other Borrower for reimbursement. Each Borrower agrees that it will not seek
to exercise any rights of contribution which it may have as a matter of law or
otherwise as against the other Borrowers hereunder or under any of the other
Loan Documents until all indebtedness arising under or in connection herewith
shall have been indefeasibly paid in full, and if by law any right of
contribution may not be postponed, then such right shall be subordinate to the
rights of Bank under this Agreement and the other Loan Documents. Until all
indebtedness arising under or in connection with this Agreement shall have been
indefeasibly paid in full, no Borrower shall be subrogated in whole or in part
to the rights of Bank, and if by law any Borrower is so subrogated, such right
shall be subordinate and junior to the rights of Bank hereunder and under the
other Loan Documents until the indefeasible payment of all indebtedness arising
under or in connection with this Agreement.

                                      -16-


     (d) It is the position of the Borrowers that each Borrower derives
significant, substantial and direct benefits from the credit accommodations that
have been made available by Bank under this Agreement and from each extension of
credit hereunder, regardless of whether such credit is disbursed to a joint
account of Borrowers or to or for the account of any Borrower.

     (e) To the extent Borrowers, or any of them, make a payment or payments to
Bank, or Bank receives any collateral proceeds, and such payment or payments or
any part thereof are subsequently invalidated, declared to be fraudulent or
preferential, set aside, voided or otherwise required to be repaid to Borrowers
or any of them, or to their estate, trustee, receiver or any other party,
including without limitation, under any bankruptcy law, state or federal law,
common law or equitable cause, then to the extent of the payment or repayment
that has been so set aside, the obligation or indebtedness which had been paid,
reduced or satisfied by such payment or repayment shall be reinstated and
continue in full force and effect as of the date such payment, reduction or
satisfaction occurred.

     SECTION 7.12.  ARBITRATION.

     (a) Arbitration.  Upon the demand of any party, any Dispute shall be
         -----------
resolved by binding arbitration (except as set forth in (e) below) in accordance
with the terms of this Agreement.  A "Dispute" shall mean any action, dispute,
claim or controversy of any kind, whether in contract or tort, statutory or
common law, legal or equitable, now existing or hereafter arising under or in
connection with, or in any way pertaining to, any of the Loan Documents, or any
past, present or future extensions of credit and other activities, transactions
or obligations of any kind related directly or indirectly to any of the Loan
Documents, including without limitation, any of the foregoing arising in
connection with the exercise of any self-help, ancillary or other remedies
pursuant to any of the Loan Documents.  Any party may by summary proceedings
bring an action in court to compel arbitration of a Dispute.  Any party who
fails or refuses to submit to arbitration following a lawful demand by any other
party shall bear all costs and expenses incurred by such other party in
compelling arbitration of any Dispute.

     (b) Governing Rules.  Arbitration proceedings shall be administered by the
         ---------------
American Arbitration Association ("AAA") or such other administrator as the
parties shall mutually agree upon in accordance with the AAA Commercial
Arbitration Rules.  All Disputes submitted to arbitration shall be resolved in
accordance with the Federal Arbitration Act (Title 9 of the United States Code),
notwithstanding any conflicting choice of law provision in any of the Loan
Documents.  The arbitration shall be conducted at a location in California
selected by the AAA or other administrator.  If there is any inconsistency
between the terms

                                      -17-


hereof and any such rules, the terms and procedures set forth herein shall
control. All statutes of limitation applicable to any Dispute shall apply to any
arbitration proceeding. All discovery activities shall be expressly limited to
matters directly relevant to the Dispute being arbitrated. Judgment upon any
award rendered in an arbitration may be entered in any court having
jurisdiction; provided however, that nothing contained herein shall be deemed to
be a waiver by any party that is a bank of the protections afforded to it under
12 U.S.C. (S)91 or any similar applicable state law.

     (c) No Waiver; Provisional Remedies, Self-Help and Foreclosure.  No
         ----------------------------------------------------------
provision hereof shall limit the right of any party to exercise self-help
remedies such as setoff, foreclosure against or sale of any real or personal
property collateral or security, or to obtain provisional or ancillary remedies,
including without limitation injunctive relief, sequestration, attachment,
garnishment or the appointment of a receiver, from a court of competent
jurisdiction before, after or during the pendency of any arbitration or other
proceeding.  The exercise of any such remedy shall not waive the right of any
party to compel arbitration or reference hereunder.

     (d) Arbitrator Qualifications and Powers; Awards.  Arbitrators must be
         --------------------------------------------
active members of the California State Bar or retired judges of the state or
federal judiciary of California, with expertise (to the extent reasonably
practicable, of 10 years or more) in the substantive laws applicable to the
subject matter of the Dispute.  Arbitrators are empowered to resolve Disputes by
summary rulings in response to motions filed prior to the final arbitration
hearing.  Arbitrators (i) shall resolve all Disputes in accordance with the
substantive law of the state of California, (ii) may grant any remedy or relief
that a court of the state of California could order or grant within the scope
hereof and such ancillary relief as is necessary to make effective any award,
and (iii) shall have the power to award recovery of all costs and fees, to
impose sanctions and to take such other actions as they deem necessary to the
same extent a judge could pursuant to the Federal Rules of Civil Procedure, the
California Rules of Civil Procedure or other applicable law.  Any Dispute in
which the amount in controversy is $5,000,000 or less shall be decided by a
single arbitrator who shall not render an award of greater than $5,000,000
(including damages, costs, fees and expenses).  By submission to a single
arbitrator, each party expressly waives any right or claim to recover more than
$5,000,000.  Any Dispute in which the amount in controversy exceeds $5,000,000
shall be decided by majority vote of a panel of three arbitrators; provided
however, that all three arbitrators must actively participate in all hearings
and deliberations.

                                      -18-


     (e) Judicial Review.  Notwithstanding anything herein to the contrary, in
         ---------------
any arbitration in which the amount in controversy exceeds $25,000,000, the
arbitrators shall be required to make specific, written findings of fact and
conclusions of law.  In such arbitrations (i) the arbitrators shall not have the
power to make any award which is not supported by substantial evidence or which
is based on legal error, (ii) an award shall not be binding upon the parties
unless the findings of fact are supported by substantial evidence and the
conclusions of law are not erroneous under the substantive law of the state of
California, and (iii) the parties shall have in addition to the grounds referred
to in the Federal Arbitration Act for vacating, modifying or correcting an award
the right to judicial review of (A) whether the findings of fact rendered by the
arbitrators are supported by substantial evidence, and (B) whether the
conclusions of law are erroneous under the substantive law of the state of
California.  Judgment confirming an award in such a proceeding may be entered
only if a court determines the award is supported by substantial evidence and
not based on legal error under the substantive law of the state of California.

     (f) Real Property Collateral; Judicial Reference.  Notwithstanding anything
         --------------------------------------------
herein to the contrary, no Dispute shall be submitted to arbitration if the
Dispute concerns indebtedness secured directly or indirectly, in whole or in
part, by any real property unless (i) the holder of the mortgage, lien or
security interest specifically elects in writing to proceed with the
arbitration, or (ii) all parties to the arbitration waive any rights or benefits
that might accrue to them by virtue of the single action rule statute of
California, thereby agreeing that all indebtedness and obligations of the
parties, and all mortgages, liens and security interests securing such
indebtedness and obligations, shall remain fully valid and enforceable.  If any
such Dispute is not submitted to arbitration, the Dispute shall be referred to a
referee in accordance with California Code of Civil Procedure Section 638 et
seq., and this general reference agreement is intended to be specifically
enforceable in accordance with said Section 638.  A referee with the
qualifications required herein for arbitrators shall be selected pursuant to the
AAA's selection procedures.  Judgment upon the decision rendered by a referee
shall be entered in the court in which such proceeding was commenced in
accordance with California Code of Civil Procedure Sections 644 and 645.

     (g) Miscellaneous.  To the maximum extent practicable, the AAA, the
         -------------
arbitrators and the parties shall take all action required to conclude any
arbitration proceeding within 180 days of the filing of the Dispute with the
AAA.  No arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its

                                      -19-


business, by applicable law or regulation, or to the extent necessary to
exercise any judicial review rights set forth herein. If more than one agreement
for arbitration by or between the parties potentially applies to a Dispute, the
arbitration provision most directly related to the Loan Documents or the subject
matter of the Dispute shall control. This arbitration provision shall survive
termination, amendment or expiration of any of the Loan Documents or any
relationship between the parties.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed as of the day and year first written above.
