changed, by an amount equal to such change in the Base Rate.  All interest chargeable under the Loan Documents shall be computed on the basis of a three hundred sixty (360) day year for the actual number of days elapsed.
60. Bank's Books and Records.  The amount and date of each Loan hereunder, the amount from time to time outstanding, the applicable interest rate in respect of each Loan, and the amount and date of any repayment hereunder, shall
be noted on Bank's books and records, which shall be conclusive evidence thereof, absent manifest error; provided, however, any failure by Bank to make any such notation, or any error in any such notation, shall not relieve Borrower of its obligations to
pay to Bank all amount s owing to Bank under or pursuant to this Agreement and each of the other Loan documents, in each case, when due in accordance with the terms hereof or thereof.
61. Payments on Non-Business Day.  In the event that any payment of any principal, interest, fees or any other amounts payable by Borrower under or pursuant to this Agreement, or under any other Loan Document shall become due on
any day which is not a Business Day, such due date shall be extended to the next succeeding Business Day, and, to the extent applicable, interest shall continue to accrue and be payable at the applicable rate(s) for and during any such extension.
62. Payment Procedures.  All sums payable by Borrower to Bank under or pursuant to this Agreement, or any other Loan Document, whether principal, interest, or otherwise, shall be paid, when due, directly to Bank at the office of
Bank identified on the signature page of this Agreement, or at such other office of Bank as Bank may designate in writing to Borrower from time to time, in immediately available United States funds, and without setoff, deduction or counterclaim.  Bank
may, in its discretion, charge any and all deposit or other accounts (including, without limitation, any account evidence by a certificate of deposit or time deposit) of Borrower maintained with Bank for all or any part of any Indebtedness then due and
payable; provided, however, that such authorization shall not affect Borrower's obligations to pay all Indebtedness when due, whether or not any such account balances maintained by Borrower with Bank are insufficient to pay any amounts then due.
63. Default Rate.  Notwithstanding anything to the contrary set forth herein, in the event that and so long as any event of Default shall have occurred and be continuing or existing, all Indebtedness outstanding under the
Revolving Credit shall bear interest at a rate equal to the then applicable interest rate plus three percent (3%), which interest, in any case, shall be payable upon demand.
64. Receipt of Payments by Bank.  Any payment by Borrower of any of the Indebtedness made by mail will be deemed tendered and received by Bank only upon actual receipt thereof by Bank at the address designated for such payment,
whether or not Bank has authorized payment by mail or in any other manner, and such payment shall not be deemed to have been made in a timely manner unless actually received by Bank on or before the date due for such payment, time being of the essence.
Borrower expressly assumes all risks of loss or liability resulting from non-delivery or delay of delivery of any item of payment transmitted by mail or in any other manner.  Acceptance by Bank of any payment in an amount less than the amount then due
shall be deemed an acceptance on account only and any failure to pay the entire amount then due shall constitute and continue to be an Event of Default hereunder, and at any time thereafter, and until the entire amount then due has been paid in full, Bank
shall be entitled to exercise any and all rights and remedies conferred upon and otherwise available to Bank hereunder or any of the other Loan Documents upon the occurrence and during the continuance of any such Event of Default.  Prior to the occurrence
of any Event of Default hereunder, Borrower shall have the right to direct other applications of any and all payments made to Bank by Borrower hereunder to the respective Indebtedness. Borrower waives the right to direct the application of any and all
payments received by Bank from and on behalf of Borrower at any time or times after the occurrence and during the continuance of any event of Default hereunder.  Borrower further agrees that after the occurrence and during the continuance of any Event of
Default hereunder, or prior to the occurrence of any Event of Default hereunder if Borrower has failed to direct to such application, Bank shall have the continuing exclusive right to apply and to reapply and all payment received by Bank at any time or
times hereafter, whether as voluntary payments, proceeds from any Collateral, offsets, or otherwise, against the Indebtedness in such order and in such manner as Bank may, in its sole discretion, deem advisable, notwithstanding any entry by Bank upon any
of its books and records.  Borrower hereby expressly agrees that, to the extent that Bank receives any payment or benefit of or otherwise upon any of the Indebtedness, and such payment or benefit, or any part thereof, is subsequently invalidated, declared
to be fraudulent or preferential, set aside, or required to be repaid to a trustee, receiver, or any other party under any bankruptcy act, state or federal law, common law, or equitable cause, then to the extent of such payment or benefit, the
Indebtedness, or part thereof, intended to be satisfied shall be revived and continued in full force and effect as if such payment or benefit had not been made by Borrower or received by Bank, and, further, any such repayment by Bank shall be added to and
be deemed to be additional Indebtedness.
65. creation of security interest
66. Grant of Security Interest.  Borrower grants and pledges to Bank a continuing security interest in all presently existing and hereafter acquired or arising Collateral in order to secure prompt payment of any and all
Indebtedness and in order to secure prompt performance by Borrower of each of its covenants and duties under the Loan Documents.  Such security interest constitutes a valid, first priority security interest in the presently existing Collateral, and will
constitute a valid, first priority security interest in Collateral acquired after the date hereof, in each case, to the extent that a security interest in such Collateral can be perfected by the filing of a financing statement or, in the case of
Collateral consisting of Instruments, Documents, Chattel Paper or certificated securities, to the extent that Bank takes possession of such Collateral.  Borrower acknowledges that Bank may place a "hold" on any deposit account pledged as
Collateral to secure the Indebtedness.  Bank agrees to execute and deliver to Borrower from time to time such subordination agreements in form and substance satisfactory to Bank as Borrower may request and as are necessary to give to other lenders which
finance equipment for Borrower a first priority security interest in the equipment financed so long as the Liens and the Indebtedness incurred with respect to such equipment financing are permitted under this Agreement.  Notwithstanding termination of
this Agreement, Bank's lien on the Collateral shall remain in effect for so long as any Indebtedness is outstanding or any loan facility is in place.
67. Delivery of additional Documentation Required.  Borrower shall from time to time execute and deliver to Bank, at the request of Bank, all negotiable Collateral, all financing statements and other documents that Bank may
reasonably request, in form satisfactory to Bank, to perfect and continue perfected Bank's security interests in the Collateral and in order to fully consummate all of the transactions contemplated under the Loan Documents.
68. Rights to Inspect.  Bank (through any of its officers, employees, or agents) shall have the right, upon reasonable prior notice, from time to time during Borrower's usual business hours, to inspect Borrower's books and to
make copies thereof and to check, test, and appraise the Collateral in order to verify Borrower's financial condition or the amount, condition of, or any other matter relating to, the Collateral.

such tax returns, and is not delinquent in filing such returns in accordance with such extensions, and have paid all taxes which have become due pursuant to those returns or pursuant to any assessments received by any such party, as the case may be, to
the extent such taxes have become due, except to the extent such tax payments are being actively and diligently contested in good faith by appropriated proceedings.
89. No Defaults.  There exists no default under the provisions of any instrument or agreement evidencing, governing or otherwise relating to any debt of Borrower or any of its Subsidiaries, or connected with any of the Permitted
Liens, or with respect to any other agreement, a default under which could have a Material Adverse Effect.
90. Actions, Suits, Litigation or Proceedings.  There are no actions, suits, litigation or proceedings, at law or in equity, and no proceedings before any governmental commission, board, bureau, or other administrative agency,
pending, or, to the best knowledge of Borrower, threatened against or affecting Borrower or any of its Subsidiaries, or any properties or rights of Borrower or any of its Subsidiaries, which, if adversely determined, could have a Material Adverse Effect.

91. Compliance with Laws.  Borrower and its Subsidiaries have each complied with all applicable laws, including, without limitation, Environmental Laws, to the extent that failure to so comply would have a Material Adverse

meaning of ERISA or incurred any liability to the Pension Benefit Guaranty Corporation ("PBGC") in connection with any employee benefit plan established or maintained by Borrower or any of its Subsidiaries, and no reportable event or prohibited
transaction, as defined in ERISA, has occurred with respect to such plans.  Neither Borrower nor any of its Subsidiaries is an "investment company" within the meaning of the Investment Company Act of 1940, as amended, nor is Borrower or any of
its Subsidiaries "Controlled" by an "investment company" within the meaning of the Investment Company Act of 1940, as amended.  Neither Borrower nor any of its Subsidiaries is engaged principally, or as one of its important activities,
directly or indirectly, in the business of extending credit for the purpose of purchasing or carrying margin stock, and none of the proceeds of any of the Loans will be used directly or indirectly, to purchase or carry any margin stock or made available
by Borrower or any of its Subsidiaries in any manner to any other Person to enable or assist such Person in purchasing or carrying margin stock.
92. Consents, Approvals and Filings, Etc.  Except as have been previously obtained or as otherwise expressly provided in this Agreement, no authorization, consent, approval, license, qualification or formal exemption from, nor
any filing, declaration or registration with, any court, environmental agency or regulatory authority or other governmental body or any securities exchange, and no material authorization, consent or approval from any other Persons, is required in
connection with the execution, delivery and performance by Borrower of this Agreement, or any of the other Loan Documents.  All such authorizations, consents, approvals, licenses, qualifications, exemptions, filings, declarations and registrations which
have previously been obtained or made, as the case may be, are in full force and effect and are not the subject of any attack, or to the knowledge of Borrower, any threatened attack, in any material respect, by appeal, direct proceeding or otherwise.
93. Environmental Representations.  Neither Borrower nor any of its Subsidiaries has reviewed any notice of any violation of any Environmental Law(s); and neither Borrower nor any of its Subsidiaries is a party to any litigation

violated any Environmental Law(s), (ii) asserts or alleges action due to the disposal, depositing, discharge, leaking or other release of any hazardous materials, or (iii) asserts or alleges that Borrower or any of its Subsidiaries is required to pay all
or a portion of any past, present or future clean-up, removal or other remedial or response action which arises out of or is related to the disposal, depositing, discharge, leaking or other release of any hazardous materials by Borrower or any of its
Subsidiaries, and which, either singularly or in the aggregate, could have a Material Adverse Effect upon the business, operations, condition (financial or otherwise), performance or properties of Borrower or any of its Subsidiaries.
94. To the best of Borrower's knowledge, there are no conditions existing currently which could subject Borrower or any of its Subsidiaries to damages, penalties, injunctive relief or clean-up costs under any applicable Environmental
Law(s), or which require, or are likely to require, clean-up, removal, remedial action or other response pursuant to any applicable environmental Law(s) by Borrower or any of its Subsidiaries, and which, in any case, either singularly or in aggregate,
could have a Material Adverse Effect upon the business, operations, conditions (financial or otherwise), performance or operations of Borrower or any of its Subsidiaries.

64. Accounts Collection.  At any time from the date of this Agreement, Bank may notify any Person owing funds to Borrower of Bank's security interest in such funds and verify the amount of such Account.  Borrower shall collect
all amounts owing to Borrower for Bank, receive in trust all payments as Bank's trustee, and, if requested or required by Bank, immediately deliver such payments to Bank in their original form as received from the Account Debtor, with property
endorsements for deposit.
65. Bank Expenses.  If Borrower fails to pay any amounts or furnish any required proof of payment due to third persons or entities, as required under the terms of this Agreement, then  Bank may do any or all of the following:

type discussed in Section 7.8 of this Agreement, and take any action with respect to such policies as Bank deems prudent.  Any amounts so paid or deposited by Bank shall constitute Bank Expenses, shall be immediately due and payable, and shall bear
interest at the then applicable rate hereinabove provided, and shall be secured by the Collateral.  Any payments made by Bank shall not constitute an agreement by Bank to make similar payments in the future or a waiver by Bank of any Event of Default
under this Agreement.
66. Bank's Liability for Collateral.  so long as Bank complies with its obligations under Section 9207 of the Code, Bank shall not in any way or manner be liable or responsible for:  (a) the safekeeping of the

person whomsoever.  All risk of loss, damage or destruction of the Collateral shall be borne by Borrower.
67. Waiver of Certain Laws.  To the extent permitted by applicable law, Borrower hereby agrees to waive, and does hereby absolutely and irrevocably waive and relinquish, the benefit and advantage of any valuation, stay,
appraisement, extension or redemption laws now existing or which may hereafter exist, which, but for this provision, might be applicable to any sale made under the judgment, order or decree of any court, on any claim for interest on the Notes, or any
security interest or mortgage contemplated by or granted under or in connection with this Agreement or the Indebtedness.
68. Waiver of Defaults.  No Default or Event of Default shall be waived by Bank except in a written instrument specifying the scope and terms of such waiver and signed by an authorized officer of Bank, and such waiver and shall
be effective only for the specific time(s) and purpose(s) given.  No single or partial exercise of any right, power or privilege hereunder, nor any delay in the exercise thereof, shall preclude other or further exercise of Bank's rights.  No waiver of any
Default or Event of Default shall extend to any other or further Default or Event of Default.  No forbearance on the part of Bank in enforcing any of Bank's rights or remedies hereunder or any of the other Loan Documents shall constitute a waiver of any
of its rights or remedies.  Borrower expressly agrees that this Section may not be waived or modified by Bank by course of performance, estoppel or otherwise.
69. Receiver.  Bank, in any action or suit to foreclose upon any of the Collateral, shall be entitled, without notice or consent, and completely without regard to the adequacy of any security for the Indebtedness, to the
appointment of a receiver of the business and premises in question, and of the rents and profits derived therefrom.  This appointment shall be in addition to any other rights, relief or remedies afforded Bank.  Such receiver, in addition to any other
rights to which he shall be entitled, shall be authorized to sell, foreclose or complete foreclosure on Collateral contemplated by this Agreement for the benefit of Bank, pursuant to provisions of applicable law.
70. Remedies Cumulative.  Bank's rights and remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative.  Bank shall have all other rights and remedies not expressly set forth herein as
provided under the UCC, by law, or in equity.  No exercise by Bank of one right or remedy shall be deemed an election, and no waiver by Bank of any Event of Default on Borrower's part shall be deemed a continuing waiver.  No delay by Bank shall constitute
a waiver, election, or acquiescence by it.  No waiver by Bank shall be effective unless made in a written document signed on behalf of Bank and then shall be effective unless made in a written document signed on behalf of Bank and then shall be effective
only in the specific instance and for the specific purpose for which it was given.
71. Demand; Protest.  Borrower waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment, not of any default, nonpayment at maturity, release, compromise, settlement, extension,
or renewal of accounts, Documents, instruments, Chattel Paper, and guarantees at any time held by Bank on which Borrower may in any way be liable.

other accounting computation is required to be made for purposes of this Agreement, it shall be done in accordance with GAAP, and all accounting terms not specifically defined in this Agreement shall be construed in accordance with GAAP.
75. Audits of Collateral; Fees.  Bank shall have the right from time to time to audit Borrower's Accounts, Inventory, or other Collateral, provided that such audits will be conducted upon reasonable notice.  Borrower agrees to
reimburse Bank, on demand, for customary and reasonable fees and costs incurred by Bank for such audits, and for each appraisal of Collateral and financial analysis and examination of Borrower performed from time to time by its agents.
76. Taxes and Fees.  Should any tax (other than a tax based upon the net income of Bank) or recording or filing fee become payable in respect of this Agreement or any of the Loan Documents, any of the Collateral, or any
amendment, modification or supplemental hereof or thereof, Borrower agrees to pay such taxes (or reimburse Bank therefor), together with any interest or penalties thereon, and agree to hold Bank harmless with respect thereto.
77. Governing Law.  This Agreement, each of the Notes, and each of the other Loan and Collateral Documents, shall be deemed to have been delivered in the State of California, and shall be governed by and construed and enforced
in accordance with the laws of the State of California, except to the extent that the Uniform Commercial Code, other personal property law or real property law of another jurisdiction where Collateral is located is applicable, and except to the extent
expressed to the contrary in any of the Loan Documents.  Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.
78. Costs and Expenses.  Borrower shall pay Bank, on demand, all costs and expenses, including, without limitation, reasonable attorneys' fees and legal expenses, incurred by Bank in perfecting, revising, protecting or enforcing
any of its rights or remedies against Borrower or any Collateral, or otherwise incurred by Bank in accordance with any Default or Event of Default or the enforcement of this Agreement, the Loan Documents, or the Indebtedness.  Following Bank's demand upon
Borrower for the payment of any such costs and expenses, and until the same are paid in full, the unpaid amount of such costs and expenses shall constitute Indebtedness and shall bear interest at the Base Rate.
79. Notices.  All notices and other communications provided for herein or in any document contemplated hereby, given hereunder or required by law to be given, shall be in writing (unless expressly provided to the contrary).  If
personally delivered, such notices shall be effective when delivered, and in the case of mailing, such notices shall be effective two (2) Business Days after sending by first class mail, postage prepaid, in each case addressed to the parties as set forth
on the signature page of this Agreement, or to such other address as a party shall have designated to the other in writing in accordance with this Section.  The giving of at least five (5) days' notice before Bank shall take any action described in any
notice shall conclusively be deemed reasonable for all purposes; provided, that this shall not be deemed to require Bank to give such five (5) days' notice, or any notice, if not specifically required to do so in this Agreement.
80. Further Action.  Borrower, from time to time, upon written request of Bank, will promptly make, execute, acknowledge and deliver, or cause to be made, executed, acknowledged and delivered, all such further and additional
instruments, and promptly take all such further action as may be required to carry out the intent and purpose of this Agreement, and to provide for the Loans under and payment of the Notes, according to the intent and purpose herein and therein expressed.
81. Successors and Assigns; Participation.  This Agreement shall be binding upon and shall inure to the benefit of Borrower and Bank and their respective successors and assigns.  The foregoing shall not authorize any assignment
or transfer by Borrower, of any of its respective rights, duties or obligations hereunder, such assignments or transfers being expressly prohibited Bank, however, may freely assign, whether by assignment, participation or otherwise, its rights and
obligations hereunder, and is hereby authorized to disclose to any such assignee or participation any financial or other information in its knowledge or possession regarding borrower, its Subsidiaries and Affiliates, or the Indebtedness.
82. Indulgence.  No delay or failure of Bank in exercising any right, power or privilege hereunder or under any of the Loan Documents shall affect such right, power or privilege, nor shall any single or partial exercise thereof
preclude any further exercise thereof, nor the exercise of any other right, power or privilege available to the Bank.  The rights and remedies of Bank hereunder are cumulative and are not exclusive of any rights or remedies of Bank.
83. Amendment and Waiver.  No amendment or waiver of any provision of this Agreement or any Loan Document, nor consent to any departure by Borrower, therefrom, shall in any event be effective unless the same shall be in writing
and signed by Bank, and then such waiver or consent shall be effective only in the specific instance(s) and for the specific time(s) and purpose(s) for which given.
84. Severability.  In case any one or more of the obligations of Borrower under this Agreement, any Note, or any of the other Loan Documents shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality
and enforceability of the remaining obligations of Borrower shall not in any way be affected or impaired thereby, and such invalidity, illegality or unenforceability in one jurisdiction shall not affect the validity, legality of enforceability of the
obligations of Borrower under this Agreement, the Notes or any of the other Loan Documents in any other jurisdiction.
85. Headings and Construction of Terms.  The headings of the various sub-Sections hereof are for convenience of reference only and shall in no way modify or affect any of the terms or provisions hereof.  Where the context herein
requires, the singular number shall include the plural, and any gender shall include any other gender.
86. Independence of Covenants.  Each covenant hereunder shall be given independent effect so that if a particular action or condition is not permitted by any such covenant, the fact that it would be permitted by an exception to,
or would be otherwise within the limitations of, another covenant shall not avoid the occurrence of any Default or Event of Default.
87. Reliance and Survival of Various Provisions.  All terms, covenants, agreements, representations and warranties of Borrower made herein or in any of the Loan Documents, or in any certificate, report, financial statement or
other document furnished by or on behalf of Borrower in connection with this Agreement or any of the Loan Documents, shall be deemed to have been relied upon by Bank, notwithstanding any investigation heretofore or hereafter made by Bank or on Bank's
behalf, and those covenants and agreements of Borrower set forth in this Agreement (together with any other indemnities of Borrower contained elsewhere in this Agreement or in any of the Loan Documents) shall survive the termination of this Agreement and
the repayment in full of the Indebtedness.
88. Effective Upon Execution.  This Agreement shall become effective upon the execution hereof by Bank and Borrower, and shall remain effective until the Indebtedness under this Agreement and each of the Notes shall have been
repaid and discharged in full and no commitment to extend any credit hereunder (whether optional or obligatory) remains outstanding.
89. Complete Agreement; Conflicts.  This Agreement, the Notes, the other Loan Documents, any agreements, certificates, or other documents given in connection with the Indebtedness under this Agreement, and any commitment letter
previously issued by Bank with respect thereto (provided that in the event of an inconsistency or conflict between this Agreement and the other Loan Documents, on one hand, and such commitment letter, on the other hand, this Agreement and the Loan
Documents shall control), contain the entire agreement of the parties thereto and supersedes all prior agreements and understandings related to the subject matter hereof, and none of the parties shall be bound by anything not expressed in writing.  In the
event that and to the extent that any of the terms, conditions or provisions of any of the other Loan Documents are inconsistent with or in conflict with any of the terms, conditions or provisions of this Agreement, the applicable terms, conditions and
provisions of this Agreement shall govern and control.
90. Confidentiality.  In handling any confidential information, Bank shall exercise the same degree of care that it exercises with respect to its own proprietary information of the same types to maintain the confidentiality of
any non-public information thereby received or received pursuant to this Agreement, except that disclosure of such information may be made: (a) to the subsidiaries or Affiliates of Bank in connection with their present or prospective business
relations with Borrower; (b) to prospective transferees or purchasers of any interest in the Loans, provided that they have entered into a comparable confidentiality agreement in favor of Borrower and have delivered a copy to Borrower; (c) as
required by law, regulations, rule or order, subpoena, judicial order or similar order; (d) as may be required in connection with the examination, audit or similar investigation of Bank; and (e) as Bank may deem appropriate in connection with
the exercise of any remedies hereunder.  Confidential information hereunder shall not include information that either (i) is in the public domain or in the knowledge or possession of Bank when disclosed to Bank, or becomes part of the public domain
after disclosure to Bank through no fault of Bank, or (ii) is disclosed to Bank by a third party, provided Bank does not have actual knowledge that such third party is prohibited from disclosing such information.
91. WAIVER OF JURY TRIAL.  BANK AND BORROWER EACH ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED.  EACH OF THEM, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT, WITH
COUNSEL OF THEIR CHOICE, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY RELATED INSTRUMENT OR LOAN DOCUMENT OR ANY OF THE TRANSACTIONS
CONTEMPLATED BY THIS AGREEMENT OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTION OF ANY OF THEM.  THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR RELINQUISHED BY BANK OR BORROWER, EXCEPT BY A
WRITTEN INSTRUMENT EXECUTED BY EACH OF THEM.
92. Counterparts.  This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which,
when taken together, shall constitute but one and the same Agreement.

WITNESS the due execution hereof as of the day and year first above written.
