2. The Company  covenants and agrees that all shares of Common Stock or Warrants
which may be delivered upon the exercise of this Warrant will, upon delivery, be
free from all taxes,  liens and charges  with  respect to the  purchase  thereof
hereunder.  However,  the Company  shall not be  obligated to deliver any Units,
Shares and Warrants pursuant to the exercise of this Warrant,  unless and until,
a current  Registration  Statement under the Securities Act of 1933, as amended,
with respect to such Units, Shares, and Warrants remains effective.  The Company
covenants  and  agrees  and will  use its best  efforts  to  cause  its  current
Registration   Statement  to  become  effective.   This  Warrant  shall  not  be
exercisable in any state where such exercise would be unlawful. The Company will
attempt  to qualify  the  shares  represented  by this  Warrant  for sale in all
jurisdictions where holders of the Company's Warrants reside.

3. The  number  of Units and  resulting  Shares  of  Common  Stock and  Warrants
purchasable  upon the exercise of this  Warrant and the purchase  price shall be
subject to adjustment from time to time as set forth below:

         REORGANIZATION, RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE.

                  If any recapitalization, reclassification or reorganization of
         the capital stock of the Company, or any consolidation or merger of the
         Company with another  corporation,  or the sale of all or substantially
         all of its assets or other  transaction shall be effected in such a way
         that  holders of Common  Stock  shall be  entitled  to  receive  stock,
         securities, or other assets or property (an "Organic Change"), then, as
         a condition of such  Organic  Change,  lawful and  adequate  provisions
         shall be made by the Company whereby the Holder hereof shall thereafter
         have the right, upon exercise of this Warrant,  to purchase and receive
         (in lieu of the Shares of the Common  Stock of the Company  immediately
         theretofore  purchasable and receivable upon the exercise of the rights
         represented by this Warrant) such Shares of stock, Units, securities or
         other assets or property as may be issued or payable with respect to or
         in exchange  for a number of  outstanding  shares of such Common  Stock
         equal to the  number  of  Shares  or Units  of such  stock  immediately
         theretofore  purchasable and receivable upon the exercise of the rights
         represented  by this  Warrant.  In the  event  of any  Organic  Change,
         appropriate  provision shall be made by the Company with respect to the
         rights and  interests of the Holder of this Warrant to the end that the
         provisions  hereof  (including,  without  limitation,   provisions  for
         adjustments  of the Exercise Price and of the number of Shares or Units
         purchasable  and  receivable  upon the exercise of this Warrant)  shall
         thereafter be  applicable,  in relation to any Shares of stock,  Units,
         securities or assets  thereafter  deliverable upon the exercise hereof.
         The  Company  will not  effect any such  consolidation,  merger or sale
         unless, prior to the consummation  thereof,  the successor  corporation
         (if other than the Company)  resulting from such  consolidation  or the
         corporation  purchasing such assets shall assume by written  instrument
         executed  and  mailed or  delivered  to the  Holder  hereof at the last
         address  of such  Holder  appearing  on the books of the  Company,  the
         obligation to deliver to such Holder,  upon  Holder's  exercise of this
         Warrant and payment of the purchase price in accordance  with the terms
         hereof,  such  Shares  of stock,  Units,  securities  or assets  as, in
         accordance with the foregoing  provisions,  such Holder may be entitled
         to purchase.

<PAGE>

                  No adjustment of the Exercise Price, however, shall be made in
         an amount less than $.01 per Unit, but any such lesser adjustment shall
         be carried  forward and shall be made at the time and together with the
         next  subsequent  adjustment  which  together with any  adjustments  so
         carried forward shall amount to $.01 per Unit or more.

4. This  Warrant  shall be callable and  redeemable  by the Company upon 30 days
written notice to the  Registered  Holder of this Warrant at $0.001 per warrant,
if not exercised prior thereto.

5. The Company  agrees at all times to reserve or hold  available  a  sufficient
number of shares of its Common Stock to cover the number of shares issuable upon
the exercise of this and other Warrants of like tenor then outstanding.

6. This  Warrant  does not entitle the  Registered  Holder  hereof to any voting
rights or other rights as a shareholder  of the Company,  or to any other rights
whatsoever except the rights set forth in this Warrant, and no dividend shall be
payable or accrue in respect of this Warrant or the interest represented hereby,
or the share purchasable  hereunder,  until or unless,  and except to the extent
that, this Warrant shall be exercised.

7. This Warrant is  exchangeable  upon the  surrender  hereof by the  Registered
Holder  to  the  Warrant  Agent  for  new  Warrants  of  like  tenor  and  date,
representing  in the  aggregate  the  right to  purchase  the  number  of shares
purchasable  hereunder,  each of such new  Warrants  to  represent  the right to
purchase such numbers as may be designated by the Registered  Holder at the time
of such surrender.  From the date this offering is closed,  this Warrant and all
rights hereunder shall be transferable  separately from the stock certificate to
which it is  attached  by the  Registered  Holder  hereof  in  person or by duly
authorized  attorney on the books of the Company upon surrender of this Warrant,
properly endorsed, to the Company. The Company may deem and treat the Registered
Holder of this Warrant at any time as the absolute owner hereof for all purposes
and shall not be affected by any notice to the contrary.

8.       REGISTRATION RIGHTS

         (a) If at any time the Company  proposes to register  the sale of Units
or Shares of Common Stock  (whether  for itself or any of its security  holders)
under the  Securities Act and the  registration  form to be used may be used for
the registration of shares underlying this Warrant (a "Piggyback Registration"),
the Company shall give prompt  written  notice to the Holder of its intention to
effect such a registration and, subject to Section 8 (b) below, shall include in
such  registration  all Units or Shares of Common Stock  underlying this Warrant
with  respect to which the Company has  received  Holder's  written  request for
inclusion in such  registration,  provided that such request must be received by
Company  within 20 days after the date of the  Company's  notice to Holder.  The
Registration  Expenses  in all  Piggyback  Registrations  shall  be  paid by the
Company.

                                      -3-

<PAGE>

         (b) If a Piggyback Registration is an underwritten primary registration
on behalf of the Company or a successor,  and the managing  underwriters  advise
the  Company in  writing  that in their  opinion  the number of shares of Common
Stock requested to be included in such registration exceeds the number which can
be sold in such offering without  adversely  affecting the  marketability of the
offering, the Company shall exclude from such registrations the excess amount of
shares of Common Stock,  and shall include in such  registration  (i) first, the
securities  the Company  proposes to sell;  (ii) second,  shares of Common Stock
requested to be included in such  registration  by the holders of all securities
of the Company  having  registration  rights,  pro rata among the owners of such
securities  on the basis of the number of shares of Common  Stock or  equivalent
shares of  Common  Stock  owned by each  such  owner,  and  (iii)  third,  other
securities  requested  to be included  in such  registration,  in the  Company's
discretion.

         (c) Whenever the Holder has  requested  that any shares of Common Stock
underlying  this Warrant be  registered  pursuant to this Section 8, the Company
shall use its best efforts to effect the registration and the sale of such Units
or Shares in accordance  with the intended  method of disposition  thereof,  and
pursuant thereto the Company shall as expeditiously as possible:

               (i)  notify the Holder of the  effectiveness of each registration
                    statement  filed  hereunder  and  prepare  and file with the
                    Securities  and  Exchange  Commission  such  amendments  and
                    supplements   to  such   registration   statement   and  the
                    prospectus used in connection  therewith as may be necessary
                    to keep such registration  statement  effective for a period
                    of not less than 180 days and comply with the  provisions of
                    the  Securities  Act with respect to the  disposition of all
                    securities  covered by such  registration  statement  during
                    such  period in  accordance  with the  intended  methods  of
                    disposition  by  the  sellers  thereof  set  forth  in  such
                    registration statement;

               (ii) furnish   the   Holder   such   number  of  copies  of  such
                    registration   statement,   each  amendment  and  supplement
                    thereto,   the  prospectus  included  in  such  registration
                    statement  (including each preliminary  prospectus) and such
                    other  documents  as such seller may  reasonably  request in
                    order to facilitate the  disposition of the shares of Common
                    Stock underlying this Warrant;

               (iii)use its best  efforts  to  register  or  qualify  the Units,
                    Warrants or Shares of Common Stock  underlying  this Warrant
                    under  such  other  securities  or  blue  sky  laws  of such
                    jurisdictions as Holder  reasonably  requests and do any and
                    all other acts and things which may be reasonably  necessary
                    or advisable to enable Holder to consummate the  disposition
                    in  such   jurisdictions  of  the  shares  of  Common  Stock
                    underlying this Warrant (provided that the Company shall not
                    be required to (A) qualify  generally  to do business in any
                    jurisdiction  where it would not  otherwise  be  required to
                    qualify  but for this  subsection,  (B)  subject  itself  to

                                      -4-

                    taxation in any such  jurisdiction or (C) consent to general
                    service of process in any such jurisdiction);

               (iv) notify  Holder,  at  any  time  when a  prospectus  relating
                    thereto is required  to be  delivered  under the  Securities
                    Act, of the  happening of any event as a result of which the
                    prospectus included in such registration  statement contains
                    an untrue  statement  of a  material  fact or omits any fact
                    necessary  to make the  statements  therein not  misleading,
                    whereupon  Holder  shall  cease  distributing  any shares of
                    Common  Stock until,  at the request of Holder,  the Company
                    shall prepare a supplement  or amendment to such  prospectus
                    so that, as thereafter  delivered to the  purchasers of such
                    shares of Common Stock, such prospectus shall not contain an
                    untrue  statement  of a  material  fact or omit to state any
                    fact   necessary   to  make  the   statements   therein  not
                    misleading; and

               (v)  use its best efforts to comply with all applicable rules and
                    regulations of the Securities and Exchange  Commission,  and
                    in the event of the  issuance  of any stop order  suspending
                    the  effectiveness  of a registration  statement,  or of any
                    order  suspending  or  preventing  the  use of  any  related
                    prospectus or  suspending  the  qualification  of any equity
                    securities included in such registration  statement for sale
                    in any jurisdiction,  the Company shall use its best efforts
                    promptly to obtain the withdrawal of such order.

         (d) All expenses incident to the Company's performance of or compliance
with this Section 8, including  without  limitation all  registration and filing
fees,  fees and expenses of compliance  with  securities or blue sky laws,  NASD
fees,   printing   expenses,   messenger  and  delivery   expenses,   fees  arid
disbursements  of  custodians,  and fees and  disbursements  of counsel  for the
Company and all independent  certified public accountants,  fees (up to $5,000),
and  disbursements  of one  counsel  for  the  Holder,  underwriters  (excluding
discounts and  commissions)  and other persons retained by the Company (all such
expenses  being herein called  "Registration  Expenses"),  shall be borne by the
Company as provided in this Section 8.

         (e) The Company  agrees to indemnify,  to the extent  permitted by law,
Holder,  its officers and directors and each person who controls  Holder (within
the  meaning  of the  Securities  Act)  against  all  losses,  claims,  damages,
liabilities  and expenses  caused by any untrue or alleged  untrue  statement of
material  fact  contained in any  registration  statement  filed by the Company,
prospectus  prepared by the Company or  preliminary  prospectus or any amendment
thereof or supplement  thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the  statements  therein
not  misleading,  except  insofar as the same are caused by or  contained in any
information  furnished  in writing to the  Company by Holder  expressly  for use
therein or by Holder's failure to deliver a copy of the  registration  statement
or prospectus or any  amendments  or  supplements  thereto after the Company has
furnished  Holder with a sufficient  number of copies of the same. In connection

                                      -5-
<PAGE>

with an underwritten  offering,  the Company shall indemnify such  underwriters,
their  officers and  directors  and each person who controls  such  underwriters
(within  the  meaning  of the  Securities  Act) to at least  the same  extent as
provided above with respect to the  indemnification  of the Holder issued by the
Company.

         (f) In connection  with any  registration  statement in which Holder is
participating,  each  Holder  shall  furnish  to the  Company  in  writing  such
information  and  affidavits  as the  Company  reasonably  requests  for  use in
connection with any such registration statement or prospectus and, to the extent
permitted by law,  shall  indemnify the Company,  its directors and officers and
each person who controls the Company  (within the meaning of the Securities Act)
against any losses, claims, damages, liabilities and expenses resulting from any
untrue  or  alleged   untrue   statement  of  material  fact  contained  in  the
registration  statement,  prospectus or preliminary  prospectus or any amendment
thereof or supplement  thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the  statements  therein
not misleading, but only to the extent that such untrue statement or omission is
contained in any information or affidavit so furnished in writing by Holder.

         (g) Any person entitled to  indemnification  under this Section 8 shall
(i) give  prompt  written  notice to the  indemnifying  party of any claim  with
respect to which it seeks  indemnification  (provided  that the  failure to give
prompt notice shall not impair any person's right to  indemnification  hereunder
to the extent such failure has not prejudiced the  indemnifying  party) and (ii)
unless in such indemnified  party's  reasonable  judgment a conflict of interest
between such indemnified and indemnifying parties may exist with respect to such
claim,  permit such indemnifying  party to assume the defense of such claim with
counsel  reasonably  satisfactory to the  indemnified  party. If such defense is
assumed,  the  indemnifying  party shall not be subject to any liability for any
settlement  made by the indemnified  party without its consent.  An indemnifying
party who is not  entitled  to, or elects not to,  assume the defense of a claim
shall not be obligated to pay the fees and expenses of more than one counsel for
all parties  indemnified by such indemnifying  party with respect to such claim,
unless  in the  reasonable  judgment  of any  indemnified  party a  conflict  of
interest  may  exist  between  such  indemnified  party  and any  other  of such
indemnified parties with respect to such claim.

         (h) The indemnification  provided for under this Section 8 shall remain
in full force and effect regardless of any investigation made by or on behalf of
the  indemnified  party or any officer,  director or controlling  person of such
indemnified  party and shall  survive the  transfer of  securities.  In order to
provide for  contribution  in any case in which  either (i) Holder makes a claim
for indemnification  pursuant to this Section 8 but it is judicially  determined
(by the entry of a final judgment or decree by a court of competent jurisdiction
and the  expiration of time to appeal or the denial of the last right of appeal)
that such  indemnification may not be enforced in such case  notwithstanding the
fact that this  Section 8 provides  for  indemnification  in such case,  or (ii)
contribution  under the  Securities Act may be required on the part of Holder in
circumstances for which  indemnification is provided under this Section 8; then,
in each such case,  the  Company  and Holder will  contribute  to the  aggregate

                                      -6-
<PAGE>

losses,  claims,  damages or liabilities which they would otherwise be obligated
to indemnify  under Sections 8(e) and 8(1) (after  contribution  from others) in
such proportions so that Holder is responsible for the portion of such aggregate
losses,  claims,  damages or liabilities  represented by the percentage that the
public offering price of its shares of Common Stock offered by the  registration
statement bears to the public  offering price of all securities  offered by such
registration  statement,  and the  Company  is  responsible  for  the  remaining
portion;  provided,  however,  that,  no person or entity  guilty of  fraudulent
misrepresentation,  within the meaning of Section 11(f) of the  Securities  Act,
shall be entitled to contribution from any person or entity who is not guilty of
such fraudulent misrepresentation.

         (i) Holder may not participate in any registration under this Section 8
which is underwritten unless Holder (i) agrees to sell Holder's shares of Common
Stock on the basis  provided in any  underwriting  arrangements  approved by the
Company and (ii) completes and executes all questionnaires,  powers of attorney,
indemnities,  underwriting  agreements  and other  documents  required under the
terms of such underwriting arrangements.

    2.  Loan
      and Terms Of Payment.

     

    2.1  Credit
      Extensions.

     

    Borrowers
      promise to pay to the order of Bank, in lawful money of the United States of
      America, the aggregate unpaid principal amount of all Credit Extensions made
      by
      Bank to Borrowers hereunder. Borrowers shall also pay interest on the unpaid
      principal amount of such Credit Extensions at rates in accordance with the
      terms
      hereof.

     

    (a)  Revolving
      Advances.

     

    (i)  Subject
      to and upon the terms and conditions of this Agreement, a Borrower may request
      Advances in an aggregate outstanding amount not to exceed the lesser of
      (i) the Revolving Line or (ii) the Borrowing Base, minus,
      in each
      case, the Term Loan, the
      aggregate face amount of all outstanding Letters of Credit and
      the
      Credit Card Exposure. Subject to the terms and conditions of this Agreement,
      amounts borrowed pursuant to this Section 2.1(a)
      may be
      repaid and reborrowed at any time prior to the Revolving Maturity Date, at
      which
      time all Advances under this Section 2.1(a)
      shall be
      immediately due and payable. Borrowers may prepay any Advances without penalty
      or premium.

     

    (ii)  Whenever
      a Borrower desires an Advance, a Borrower will notify Bank by facsimile
      transmission or telephone no later than 3:00 p.m. Pacific time, on the
      Business Day that the Advance is to be made. Each such notification shall be
      promptly confirmed by a Payment/Advance Form in substantially the form of
Exhibit A
      hereto.
      Bank is authorized to make Advances under this Agreement, based upon
      instructions received from a Responsible Officer or a designee of a Responsible
      Officer, or without instructions if in Bank’s discretion such Advances are
      necessary to meet Obligations which have become due and remain unpaid. Bank
      shall be entitled to rely on any telephonic notice given by a person who Bank
      reasonably believes to be a Responsible Officer or a designee thereof, and
      Borrowers shall indemnify and hold Bank harmless for any damages or loss
      suffered by Bank as a result of such reliance. Bank will credit the amount
      of
      Advances made under this Section 2.1(a)
      to
      Borrower’s deposit account.

     

    (b)  Term
      Loan.

     

    (i)  Subject
      to and upon the terms and conditions of this Agreement, Bank agrees to make
      a
      Term Loan to Borrowers on the Closing Date in the amount up to the lesser of
      (i)
      $2,500,000 or (ii) the Borrowing Base (the “Term Loan”). The Term Loan includes
      a refinancing of a principal amount of $1,000,000 that Bank advanced under
      the
      Original Agreement.

     

    (ii)  The
      Term
      Loan shall be payable in thirty (30) equal monthly installments of principal,
      plus all accrued interest, beginning on January 10, 2007, and continuing on
      the
      same day of each month thereafter through June 10, 2009, at which time all
      amounts owing under this Section 2.1(b)
      and any
      other amounts owing under this Agreement shall be immediately due and payable.
      

     

    (c)  Letters
      of Credit.
      Subject
      to the terms and conditions of this Agreement, at any time prior to the
      Revolving Maturity Date, Bank agrees to issue letters of credit for the account
      of a Borrower (each, a “Letter of Credit” and collectively, the “Letters of
      Credit”) in an aggregate outstanding face amount not to exceed the lesser of the
      Revolving Line or the Borrowing Base minus,
      in each
      case, the Term Loan and the aggregate amount of the outstanding Advances,
      provided that the aggregate face amount of all outstanding Letters of Credit
      shall not exceed $500,000. All Letters of Credit shall be, in form and
      substance, acceptable to Bank in its sole discretion and shall be subject to
      the
      terms and conditions of Bank’s form of standard application and letter of credit
      agreement (the “Application”), which Borrowers hereby agree to execute. On any
      drawn but unreimbursed Letter of Credit, the unreimbursed amount shall be deemed
      an Advance under Section 2.1(a), but shall bear interest at a floating rate
      equal to the Prime Rate plus 2.0%. At any time, and in any case by the Revolving
      Maturity Date, Borrower shall secure in cash all obligations under any
      outstanding Letters of Credit in an amount equal to 110% of the face amount
      of
      the Letters of Credit, on terms acceptable to Bank, in which case the
      cash-secured Letter of Credit shall be excluded from outstanding Credit
      Extensions in the calculation of availability under Section 2.1. The obligation
      of Borrowers to reimburse Bank for drawings made under Letters of Credit shall
      be absolute, unconditional and irrevocable, and shall be performed strictly
      in
      accordance with the terms of this Agreement, the Application, and such Letters
      of Credit, under all circumstances whatsoever. Borrowers shall indemnify,
      defend, protect, and hold Bank harmless from any loss, cost, expense or
      liability, including, without limitation, reasonable attorneys’ fees, arising
      out of or in connection with any Letters of Credit, except for expenses caused
      by Bank’s gross negligence or willful misconduct.

     

    2.2  Overadvances.
      If the
      aggregate amount of the outstanding Advances and Term Loan plus
      the
      aggregate face amount of all outstanding Letters of Credit and the Credit Card
      Exposure exceeds the lesser of the Revolving Line or the Borrowing Base at
      any
      time, Borrowers shall immediately pay to Bank, in cash, the amount of such
      excess.

     

    2.3  Interest
      Rates, Payments, and Calculations.

     

    (a)  Interest
      Rates.

     

    (i)  Advances.
      Except
      as set forth in Section 2.3(b),
      the
      Advances shall bear interest, on the outstanding Daily Balance thereof, at
      a
      rate equal to one-half of one percent (0.50%) above the Prime Rate.

     

    (ii)  Term
      Loan.
      Except
      as set forth in Section  2.3(b),
      the
      Term Loan shall bear interest, on the outstanding Daily Balance thereof, at
      a
      rate equal to one percent (1.0%) above the Prime Rate.

     

    (b)  Late
      Fee; Default Rate.
      If any
      payment is not made on the date such payment is due, Borrowers shall pay Bank
      a
      late fee equal to the lesser of (i) five percent (5%) of the amount of such
      unpaid amount or (ii) the maximum amount permitted to be charged under
      applicable law. All Obligations shall bear interest, from and after the
      occurrence and during the continuance of an Event of Default, at a rate equal
      to
      five (5) percentage points above the interest rate applicable immediately prior
      to the occurrence of the Event of Default.

     

    (c)  Payments.
      Interest hereunder shall be due and payable on the tenth calendar day of each
      month during the term hereof. Bank shall, at its option, charge such interest,
      all Bank Expenses, and all Periodic Payments against any of Borrowers’ deposit
      accounts or against the Revolving Line, in which case those amounts shall
      thereafter accrue interest at the rate then applicable hereunder. Any interest
      not paid when due shall be compounded by becoming a part of the Obligations,
      and
      such interest shall thereafter accrue interest at the rate then applicable
      hereunder. All payments shall be free and clear of any taxes, withholdings,
      duties, impositions or other charges, to the end that Bank will receive the
      entire amount of any Obligations payable hereunder, regardless of source of
      payment.

     

    (d)  Computation.
      In the
      event the Prime Rate is changed from time to time hereafter, the applicable
      rate
      of interest hereunder shall be increased or decreased, effective as of the
      day
      the Prime Rate is changed, by an amount equal to such change in the Prime 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.

     

    2.4  Crediting
      Payments.
      Prior
      to the occurrence of an Event of Default, Bank shall credit a wire transfer
      of
      funds, check or other item of payment to such deposit account or Obligation
      as
      Borrowers specify. After the occurrence of an Event of Default, the receipt
      by
      Bank of any wire transfer of funds, check, or other item of payment shall be
      immediately applied to conditionally reduce Obligations, but shall not be
      considered a payment on account unless such payment is of immediately available
      federal funds or unless and until such check or other item of payment is honored
      when presented for payment. Notwithstanding anything to the contrary contained
      herein, any wire transfer or payment received by Bank after 12:00 noon
      Pacific time shall be deemed to have been received by Bank as of the opening
      of
      business on the immediately following Business Day. Whenever any payment to
      Bank
      under the Loan Documents would otherwise be due (except by reason of
      acceleration) on a date that is not a Business Day, such payment shall instead
      be due on the next Business Day, and additional fees or interest, as the case
      may be, shall accrue and be payable for the period of such
      extension.

     

    2.5  Fees.
      Borrowers shall pay to Bank the following:

     

    (a)  Facility
      Fee.
      On the
      Closing Date, a Facility Fee equal to $37,500, which shall be nonrefundable;
      and

     

    (b)  Bank
      Expenses.
      On the
      Closing Date, all Bank Expenses incurred through the Closing Date, including
      reasonable attorneys’ fees and expenses and, after the Closing Date, all Bank
      Expenses, including reasonable attorneys’ fees and expenses, as and when they
      are incurred by Bank.

     

    2.6  Term.
      This
      Agreement shall become effective on the Closing Date and, subject to
      Section 12.7,
      shall
      continue in full force and effect for so long as any Obligations remain
      outstanding or Bank has any obligation to make Credit Extensions under this
      Agreement. Notwithstanding the foregoing, Bank shall have the right to terminate
      its obligation to make Credit Extensions under this Agreement immediately and
      without notice upon the occurrence and during the continuance of an Event of
      Default. Notwithstanding termination, Bank’s Lien on the Collateral shall remain
      in effect for so long as any Obligations are outstanding.

    (a)  timely
      receipt by Bank of the Payment/Advance Form as provided in
      Section 2.1;

      though made at and as of each such date, and no Event of Default shall have
      occurred and be continuing, or would exist after giving effect to such Credit
      Extension. The making of each Credit Extension shall be deemed to be a
      representation and warranty by Borrower on the date of such Credit Extension
      as
      to the accuracy of the facts referred to in this Section 3.2.

     

    4.  Creation
      of Security Interest.

     

    4.1  Grant
      of Security Interest.
      Each
      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 repayment of any and all Obligations and in order to secure prompt
      performance by Borrowers of each of its covenants and duties under the Loan
      Documents. Except as set forth in the Schedule, 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.

     

    4.2  Delivery
      of Additional Documentation Required.
      Each
      Borrower shall from time to time execute and deliver to Bank, at the request
      of

      that Bank may reasonably request, in form satisfactory to Bank, to perfect
      and
      continue the perfection of Bank’s security interests in the Collateral and in
      order to fully consummate all of the transactions contemplated under the Loan
      Documents.
      Borrowers from time to time may deposit with Bank specific time deposit accounts
      to secure specific Obligations. Borrowers authorize Bank to hold such balances
      in pledge and to decline to honor any drafts thereon or any request by a
      Borrower or any other Person to pay or otherwise transfer any part of such
      balances for so long as the Obligations are outstanding.

     

    4.3  Right
      to Inspect.
      Bank
      (through any of its officers, employees, or agents) shall have the right, upon
      reasonable prior notice, from time to time during Borrowers’ usual business
      hours but no more than twice a year (unless an Event of Default has occurred
      and
      is continuing), to inspect Borrowers’ Books and to make copies thereof and to
      check, test, and appraise the Collateral in order to verify Borrowers’ financial
      condition or the amount, condition of, or any other matter relating to, the
      Collateral.

     

    5.  Representations
      and Warranties.

     

    Each
      Borrower represents and warrants as follows:

     

    5.1  Due
      Organization and Qualification.
      Borrower and each Subsidiary is a corporation duly existing under the laws
      of
      its state of incorporation and qualified and licensed to do business in any
      state in which the conduct of its business or its ownership of property requires
      that it be so qualified.

     

    5.2  Due
      Authorization; No Conflict.
      The
      execution, delivery, and performance of the Loan Documents are within Borrower’s
      powers, have been duly authorized, and are not in conflict with nor constitute
      a
      breach of any provision contained in Borrower’s Articles of Incorporation or
      Bylaws, nor will they constitute an event of default under any material
      agreement to which Borrower is a party or by which Borrower is bound. Borrower
      is not in default under any material agreement to which it is a party or by
      which it is bound.

     

    5.3  No
      Prior Encumbrances.
      Borrower has good and marketable title to its property, free and clear of Liens,
      except for Permitted Liens.

     

    5.4  Bona
      Fide Eligible Accounts.
      The
      Eligible Accounts are bona fide existing obligations. The property and services
      giving rise to such Eligible Accounts has been delivered or rendered to the
      account debtor or to the account debtor’s agent for immediate and unconditional
      acceptance by the account debtor. Borrower has not received notice of actual
      or
      imminent Insolvency Proceeding of any account debtor that is included in any
      Borrowing Base Certificate as an Eligible Account.

     

    5.5  Merchantable
      Inventory.
      All
      Inventory is in all material respects of good and marketable quality, free
      from
      all material defects, except for Inventory for which adequate reserves have
      been
      made.

     

    5.6  Intellectual
      Property Collateral.
      Borrower is the sole owner of the Intellectual Property Collateral, except
      for
      non-exclusive licenses granted by Borrower to its customers in the ordinary
      course of business. Each of the Patents is valid and enforceable, and no part
      of
      the Intellectual Property Collateral has been judged invalid or unenforceable,
      in whole or in part, and no claim has been made that any part of the
      Intellectual Property Collateral violates the rights of any third party. Except
      as set forth in the Schedule, Borrower’s rights as a licensee of intellectual
      property do not give rise to more than five percent (5%) of its gross revenue
      in
      any given month, including without limitation revenue derived from the sale,
      licensing, rendering or disposition of any product or service. Except as set
      forth in the Schedule, Borrower is not a party to, or bound by, any agreement
      that restricts the grant by Borrower of a security interest in Borrower’s rights
      under such agreement.

     

    5.7  Name;
      Location of Chief Executive Office.
      Except
      as disclosed in the Schedule, Borrower has not done business under any name
      other than that specified on the signature page hereof. The chief executive
      office of Borrower is located at the address indicated in
      Section 10
      hereof.
      All
      Borrower’s Inventory and Equipment is located only at the location set forth in
      Section 10 hereof and at Borrower’s premises in Sunnyvale,
      California.

     

    5.8  Litigation.
      Except
      as set forth in the Schedule, there are no actions or proceedings pending by
      or
      against Borrower or any Subsidiary before any court or administrative agency
      in
      which an adverse decision could have a Material Adverse Effect, or a material
      adverse effect on Borrower’s interest or Bank’s security interest in the
      Collateral.

     

    5.9  No
      Material Adverse Change in Financial Statements.
      All
      consolidated and consolidating financial statements related to Borrower and
      any
      Subsidiary that Bank has received from Borrower fairly present in all material
      respects Borrower’s financial condition as of the date thereof and Borrower’s
      consolidated and consolidating results of operations for the period then ended.
      There has not been a material adverse change in the consolidated or the
      consolidating financial condition of Borrower since the date of the most recent
      of such financial statements submitted to Bank. 

     

    5.10  Solvency,
      Payment of Debts.
      Borrower is solvent and able to pay its debts (including trade debts) as they
      mature.

     

    5.11  Regulatory
      Compliance.
      Borrower and each Subsidiary have met the minimum funding requirements of ERISA
      with respect to any employee benefit plans subject to ERISA, and no event has
      occurred resulting from Borrower’s failure to comply with ERISA that could
      result in Borrower’s incurring any material liability. Borrower is not an
“investment company” or a company “controlled” by an “investment company” within
      the meaning of the Investment Company Act of 1940. Borrower is not engaged
      principally, or as one of the important activities, in the business of extending
      credit for the purpose of purchasing or carrying margin stock (within the
      meaning of Regulations T and U of the Board of Governors of the Federal
      Reserve System). Borrower has complied with all the provisions of the Federal
      Fair Labor Standards Act. Borrower has not violated any statutes, laws,
      ordinances or rules applicable to it, violation of which could have a Material
      Adverse Effect.

     

    5.12  Environmental
      Condition.
      Except
      as disclosed in the Schedule, none of Borrower’s or any Subsidiary’s properties
      or assets has ever been used by Borrower or any Subsidiary or, to the best
      of
      Borrower’s knowledge, by previous owners or operators, in the disposal of, or to
      produce, store, handle, treat, release, or transport, any hazardous waste or
      hazardous substance other than in accordance with applicable law; to the best
      of
      Borrower’s knowledge, none of Borrower’s properties or assets has ever been
      designated or identified in any manner pursuant to any environmental protection
      statute as a hazardous waste or hazardous substance disposal site, or a
      candidate for closure pursuant to any environmental protection statute; no
      lien
      arising under any environmental protection statute has attached to any revenues
      or to any real or personal property owned by Borrower or any Subsidiary; and
      neither Borrower nor any Subsidiary has received a summons, citation, notice,
      or

      or

      intellectual property rights now owned or hereafter developed or acquired by

      rights.

     

    (b)  Borrower
      shall promptly give Bank written notice of any applications or registrations
      of
      intellectual property rights filed with the United States Patent and Trademark

      as
      such title will appear on such applications or registrations, and the date
      such
      applications or registrations will be filed; (ii) prior to the filing of any
      such applications or registrations, execute such documents as Bank may
      reasonably request for Bank to maintain its perfection in such intellectual
      property rights to be registered by Borrower; (iii) upon the request of Bank,

      and

    (e)  Borrower
      shall (i) protect, defend and maintain the validity and enforceability of the
      trade secrets, Trademarks, Patents and Copyrights, (ii) use commercially
      reasonable efforts to detect infringements of the Trademarks, Patents and

      detected and (iii) not allow any material Trademarks, Patents or Copyrights
      to
      be abandoned, forfeited or dedicated to the public without the written consent
      of Bank, which shall not be unreasonably withheld.

     

    (f)  Bank
      may
      audit Borrower’s Intellectual Property Collateral to confirm compliance with
      this Section 6.12, provided such audit may not occur more often than once per
      year, unless an Event of Default has occurred and is continuing. Bank shall
      have
      the right, but not the obligation, to take, at Borrower’s sole expense, any
      actions that Borrower is required under this Section 6.12 to take but which
      Borrower fails to take, after 15 days’ notice to Borrower. Borrower shall
      reimburse and indemnify Bank for all reasonable costs and reasonable expenses
      incurred in the reasonable exercise of its rights under this Section

      terms of such license or agreement with a description of its likely impact
      on
      Borrower’s business or financial condition; and (ii) in good faith use
      commercially reasonable efforts to obtain the consent of, or waiver by, any
      person whose consent or waiver is necessary for Borrower’s interest in such
      licenses or contract rights to be deemed Collateral and for Bank to have a
      security interest in it that might otherwise be restricted by the terms of
      the
      applicable license or agreement, whether now existing or entered into in the
      future, provided, however, that the failure to obtain any such consent or waiver
      shall not constitute a default under this Agreement. See Schedule for current
      license agreements.

     

    6.13  Further
      Assurances.
      At any
      time and from time to time Borrower shall execute and deliver such further
      instruments and take such further action as may reasonably be requested by

      agency, and the same is not paid within ten (10) days after such Borrower
      receives notice thereof, provided that none of the foregoing shall constitute
      an
      Event of Default where such action or event is stayed or an adequate bond has
      been posted pending a good faith contest by Borrowers (provided that no Credit
      Extensions will be required to be made during such cure period);

      there is a default or other failure to perform in any agreement to which a
      Borrower is a party or by which it is bound resulting in a right by a third
      party or parties, whether or not exercised, to accelerate the maturity of any
      Indebtedness in an amount in excess of Fifty Thousand Dollars ($50,000) or
      which
      could have a Material Adverse Effect;

     

    8.7  Judgments.
      If a
      judgment or judgments for the payment of money in an amount, individually or
      in
      the aggregate, of at least Fifty Thousand Dollars ($50,000) shall be rendered
      against a Borrower and shall remain unsatisfied and unstayed for a period of
      ten
      (10) days (provided that no Credit Extensions will be made prior to the
      satisfaction or stay of such judgment); or

     

    8.8  Misrepresentations.
      If any
      material misrepresentation or material misstatement exists now or hereafter
      in
      any warranty or representation set forth herein or in any certificate delivered
      to Bank by any Responsible Officer pursuant to this Agreement or to induce
      Bank
      to enter into this Agreement or any other Loan Document.

     

    9.  Bank’s
      Rights and Remedies.

     

    9.1  Rights
      and Remedies.
      Upon
      the occurrence and during the continuance of an Event of Default, Bank may,
      at
      its election, without notice of its election and without demand, do any one
      or
      more of the following, all of which are authorized by Borrowers:

     

    (a)  Declare
      all Obligations, whether evidenced by this Agreement, by any of the other Loan
      Documents, or otherwise, immediately due and payable (provided that upon the
      occurrence of an Event of Default described in Section 8.5,
      all
      Obligations shall become immediately due and payable without any action by
      Bank);

     

    (b)  Cease
      advancing money or extending credit to or for the benefit of Borrowers under
      this Agreement or under any other agreement between a Borrower and
      Bank;

     

    (c)  Settle
      or
      adjust disputes and claims directly with account debtors for amounts, upon
      terms
      and in whatever order that Bank reasonably considers advisable;

     

    (d)  Make
      such
      payments and do such acts as Bank considers necessary or reasonable to protect
      its security interest in the Collateral. Borrowers agree to assemble the
      Collateral if Bank so requires, and to make the Collateral available to Bank
      as
      Bank may designate. Borrowers authorize Bank to enter the premises where the
      Collateral is located, to take and maintain possession of the Collateral, or
      any
      part of it, and to pay, purchase, contest, or compromise any encumbrance,
      charge, or lien which in Bank’s determination appears to be prior or superior to
      its security interest and to pay all expenses incurred in connection therewith.
      With respect to any of a Borrower’s owned premises, each Borrower hereby grants
      Bank a license to enter into possession of such premises and to occupy the
      same,
      without charge, in order to exercise any of Bank’s rights or remedies provided
      herein, at law, in equity, or otherwise;

     

    (e)  Set
      off
      and apply to the Obligations any and all (i) balances and deposits of a
      Borrower held by Bank, or (ii) indebtedness at any time owing to or for the
      credit or the account of a Borrower held by Bank;

     

    (f)  Ship,
      reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise
      for sale, and sell (in the manner provided for herein) the Collateral. Bank
      is
      hereby granted a license or other right, solely pursuant to the provisions
      of
      this Section 9.1,
      to use,
      without charge, each Borrower’s labels, patents, copyrights, rights of use of
      any name, trade secrets, trade names, trademarks, service marks, and advertising
      matter, or any property of a similar nature, as it pertains to the Collateral,
      in completing production of, advertising for sale, and selling any Collateral
      and, in connection with Bank’s exercise of its rights under this
      Section 9.1,
      each
      Borrower’s rights under all licenses and all franchise agreements shall inure to
      Bank’s benefit;

     

    (g)  Dispose
      of the Collateral by way of one or more contracts or transactions, for cash
      or
      on terms, in such manner and at such places (including each Borrower’s premises)
      as Bank determines is commercially reasonable, and apply any proceeds to the
      Obligations in whatever manner or order Bank deems appropriate;

     

    (h)  Bank
      may
      credit bid and purchase at any public sale; and

     

    (i)  Any
      deficiency that exists after disposition of the Collateral as provided above
      will be paid immediately by Borrowers.

     

    9.2  Power
      of Attorney. Effective
      only upon the occurrence and during the continuance of an Event of Default,
      each
      Borrower irrevocably appoints Bank (and any of Bank’s designated officers, or
      employees) as such Borrower’s true and lawful attorney to: (a) send requests for
      verification of Accounts or notify account debtors of Bank’s security interest
      in the Accounts; (b) endorse such Borrower’s name on any checks or other forms
      of payment or security that may come into Bank’s possession; (c) sign such
      Borrower’s name on any invoice or bill of lading relating to any Account, drafts
      against account debtors, schedules and assignments of Accounts, verifications
      of
      Accounts, and notices to account debtors; (d) dispose of any Collateral; (e)
      make, settle, and adjust all claims under and decisions with respect to such
      Borrower’s policies of insurance; (f) settle and adjust disputes and claims
      respecting the accounts directly with account debtors, for amounts and upon
      terms which Bank determines to be reasonable; and (g) to file, in its sole
      discretion, one or more financing or continuation statements and amendments
      thereto, relative to any of the Collateral. The appointment of Bank as each
      Borrower’s attorney in fact, and each and every one of Bank’s rights and powers,
      being coupled with an interest, is irrevocable until all of the Obligations
      have
      been fully repaid and performed and Bank’s obligation to provide Credit
      Extensions hereunder is terminated.

     

    9.3  Accounts
      Collection.
      At any
      time after the occurrence of an Event of Default, Bank may notify any Person
      owing funds to a Borrower of Bank’s security interest in such funds and verify
      the amount of such Account. Borrowers shall collect all amounts owing to a
      Borrower for Bank, receive in trust all payments as Bank’s trustee, and
      immediately deliver such payments to Bank in their original form as received
      from the account debtor, with proper endorsements for deposit.

     

    9.4  Bank
      Expenses.
      If a
      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 after reasonable notice to
      Borrowers: (a) make payment of the same or any part thereof; (b) set
      up such reserves under a loan facility in Section 2.1 as Bank deems necessary
      to
      protect Bank from the exposure created by such failure; or (c) obtain and
      maintain insurance policies of the type discussed in Section 6.6
      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.

     

    9.5  Bank’s
      Liability for Collateral.
      So long
      as Bank complies with reasonable banking practices, Bank shall not in any way
      or
      manner be liable or responsible for: (a) the safekeeping of the Collateral;
      (b) any loss or damage thereto occurring or arising in any manner or
      fashion from any cause; (c) any diminution in the value thereof; or
      (d) any act or default of any carrier, warehouseman, bailee, forwarding
      agency, or other person whomsoever. All risk of loss, damage or destruction
      of
      the Collateral shall be borne by Borrowers.

     

    9.6  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 inconsistent herewith as provided under the Code, 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 a 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 only
      in
      the specific instance and for the specific purpose for which it was
      given.

     

    9.7  Demand;
      Protest.
      Each
      Borrower waives demand, protest, notice of protest, notice of default or
      dishonor, notice of payment and nonpayment, notice 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 a Borrower may in any way be liable.

     

    10.  Notices.

     

    Unless
      otherwise provided in this Agreement, all notices or demands by any party
      relating to this Agreement or any other agreement entered into in connection
      herewith shall be in writing and (except for financial statements and other
      informational documents which may be sent by first-class mail, postage prepaid)
      shall be personally delivered or sent by a recognized overnight delivery
      service, certified mail, postage prepaid, return receipt requested, or by
      telefacsimile to a Borrower or to Bank, as the case may be, at its addresses
      set

    11.  CHOICE
      OF LAW AND VENUE; JURY TRIAL WAIVER.

     

    This
      Agreement shall be governed by, and construed in accordance with, the internal
      laws of the State of California, without regard to principles of conflicts
      of
      law. Each Borrower and Bank hereby submits to the exclusive jurisdiction of
      the
      state and Federal courts located in the County of Santa Clara, State of
      California. EACH BORROWER AND BANK EACH HEREBY WAIVE THEIR RESPECTIVE RIGHTS
      TO
      A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY
      OF
      THE LOAN DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING
      CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW
      OR
      STATUTORY CLAIMS. EACH PARTY RECOGNIZES AND AGREES THAT THE FOREGOING WAIVER
      CONSTITUTES A MATERIAL INDUCEMENT FOR IT TO ENTER INTO THIS AGREEMENT. EACH
      PARTY REPRESENTS AND WARRANTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL
      COUNSEL AND THAT IT KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS
      FOLLOWING CONSULTATION WITH LEGAL COUNSEL. 

     

    If
      the
      jury waiver set forth in Section is not enforceable, then any dispute,
      controversy or claim arising out of or relating to this Agreement, the Loan
      Documents or any of the transactions contemplated therein shall be settled
      by
      judicial reference pursuant to Code of Civil Procedure Section 638 et seq.
      before a referee sitting without a jury, such referee to be mutually acceptable
      to the parties or, if no agreement is reached, by a referee appointed by the
      Presiding Judge of the California Superior Court for Santa Clara County. This
      Section shall not restrict a party from exercising remedies under the Code
      or
      from exercising pre-judgment remedies under applicable law.

     

    12.  General
      Provisions.

     

    12.1  Successors
      and Assigns.
      This
      Agreement shall bind and inure to the benefit of the respective successors
      and
      permitted assigns of each of the parties; provided, however, that neither this
      Agreement nor any rights hereunder may be assigned by a Borrower without Bank’s
      prior written consent, which consent may be granted or withheld in Bank’s sole
      discretion. Bank shall have the right without the consent of or notice to
      Borrowers to sell, transfer, negotiate, or grant participation in all or any
      part of, or any interest in, Bank’s obligations, rights and benefits
      hereunder.

     

    12.2  Indemnification.
      Each
      Borrower shall defend, indemnify and hold harmless Bank and its officers,
      employees, and agents against: (a) all obligations, demands, claims, and
      liabilities claimed or asserted by any other party in connection with the
      transactions contemplated by this Agreement; and (b) all losses or Bank
      Expenses in any way suffered, incurred, or paid by Bank as a result of or in
      any
      way arising out of, following, or consequential to transactions between Bank
      and
      Borrowers whether under this Agreement, or otherwise (including without
      limitation reasonable attorneys’ fees and expenses), except for losses caused by
      Bank’s gross negligence or willful misconduct.

     

    12.3  Time
      of Essence.
      Time is
      of the essence for the performance of all obligations set forth in this
      Agreement.

     

    12.4  Severability
      of Provisions.
      Each
      provision of this Agreement shall be severable from every other provision of
      this Agreement for the purpose of determining the legal enforceability of any
      specific provision.

     

    12.5  Original
      Agreements. Amendments in Writing, Integration.
      Bank
      waives Borrower’s failure to comply the minimum quick ratio covenant specified
      in the Original Agreements. This Agreement amends and restates the terms of
      the
      Original Agreements. Neither this Agreement nor the Loan Documents can be
      amended or terminated orally. All prior agreements, understandings,
      representations, warranties, and negotiations between the parties hereto with
      respect to the subject matter of this Agreement and the Loan Documents, if
      any,
      are merged into this Agreement and the Loan Documents, provided any financing
      statements filed in connection with the Original Agreements shall continue
      to
      perfect Bank’s security interest in the Collateral.

     

    12.6  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.

     

    12.7  Survival.
      All
      covenants, representations and warranties made in this Agreement shall continue
      in full force and effect so long as any Obligations remain outstanding or Bank
      has any obligation to make Credit Extensions to Borrowers. The obligations
      of
      Borrowers to indemnify Bank with respect to the expenses, damages, losses,
      costs
      and liabilities described in Section 12.2
      shall
      survive until all applicable statute of limitations periods with respect to
      actions that may be brought against Bank have run.

     

    12.8  Confidentiality.
      In
      handling any confidential information Bank and all employees and agents of
      Bank,
      including but not limited to accountants, 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 (i) to the subsidiaries or affiliates of Bank in
      connection with their present or prospective business relations with Borrowers,
      (ii) to prospective transferees or purchasers of any interest in the Loans,
      provided that they have entered into a comparable confidentiality agreement
      in
      favor of Borrowers and have delivered a copy to Borrowers, (iii) as
      required by law, regulations, rule or order, subpoena, judicial order or similar
      order, (iv) as may be required in connection with the examination, audit or
      similar investigation of Bank and (v) as Bank may determine in connection
      with the enforcement of any remedies hereunder. Confidential information
      hereunder shall not include information that either: (a) 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 (b) 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.

     

    12.9  Effect
      of Amendment and Restatement.
      This
      Agreement is intended to and does completely amend and restate, without
      novation, the Original Agreement. All security interests granted under the
      Original Agreement are hereby confirmed and ratified and shall continue to
      secure all Obligations under this Agreement.

     

    12.10  Patriot
      Act.
      To help
      the government fight the funding of terrorism and money laundering activities,
      Federal law requires all financial institutions to obtain, verify, and record
      information that identifies each person who opens an account. WHAT THIS MEANS
      FOR YOU: when you open an account, we will ask your name, address, date of
      birth, and other information that will allow us to identify you. We may also
      ask
      to see your driver’s license or other identifying documents.

     

    13.  CO-BORROWER
      PROVISIONS.

     

    13.1  Primary
      Obligation.
      This
      Agreement is a primary and original obligation of each Borrower and shall remain
      in effect notwithstanding future changes in conditions, including any change
      of
      law or any invalidity or irregularity in the creation or acquisition of any
      Obligations or in the execution or delivery of any agreement between Bank and
      any Borrower. Each Borrower shall be liable for existing and future Obligations
      as fully as if all of all Credit Extensions were advanced to such Borrower.
      Bank
      may rely on any certificate or representation made by any Borrower as made
      on
      behalf of, and binding on, all Borrowers, including without limitation
      Disbursement Request Forms, Borrowing Base Certificates and Compliance
      Certificates.

     

    13.2  Enforcement
      of Rights.
      Borrowers are jointly and severally liable for the Obligations and Bank may
      proceed against one or more of the Borrowers to enforce the Obligations without
      waiving its right to proceed against any of the other Borrowers.

     

    13.3  Borrowers
      as Agents.
      Each
      Borrower appoints the other Borrower as its agent with all necessary power
      and
      authority to give and receive notices, certificates or demands for and on behalf
      of both Borrowers, to act as disbursing agent for receipt of any Credit
      Extensions on behalf of each Borrower and to apply to Bank on behalf of each
      Borrower for Credit Extensions, any waivers and any consents. This authorization
      cannot be revoked, and Bank need not inquire as to each Borrower’s authority to
      act for or on behalf of Borrower.

     

    13.4  Subrogation
      and Similar Rights.
      Notwithstanding any other provision of this Agreement or any other Loan
      Document, each Borrower irrevocably waives all rights that it may have at law
      or
      in equity (including, without limitation, any law subrogating the Borrower
      to
      the rights of Bank under the Loan Documents) to seek contribution,
      indemnification, or any other form of reimbursement from any other Borrower,
      or
      any other Person now or hereafter primarily or secondarily liable for any of
      the
      Obligations, for any payment made by the Borrower with respect to the
      Obligations in connection with the Loan Documents or otherwise and all rights
      that it might have to benefit from, or to participate in, any security for
      the
      Obligations as a result of any payment made by the Borrower with respect to
      the
      Obligations in connection with the Loan Documents or otherwise. Any agreement
      providing for indemnification, reimbursement or any other arrangement prohibited
      under this Section 14.4 shall be null and void. If any payment is made to a
      Borrower in contravention of this Section 14.4, such Borrower shall hold such
      payment in trust for Bank and such payment shall be promptly delivered to Bank
      for application to the Obligations, whether matured or unmatured.

     

    13.5  Waivers
      of Notice.
      Except
      as otherwise provided in this Agreement, each Borrower waives notice of
      acceptance hereof; notice of the existence, creation or acquisition of any
      of
      the Obligations; notice of an Event of Default; notice of the amount of the
      Obligations outstanding at any time; notice of intent to accelerate; notice
      of
      acceleration; notice of any adverse change in the financial condition of any
      other Borrower or of any other fact that might increase the Borrower’s risk;
      presentment for payment; demand; protest and notice thereof as to any
      instrument; default; and all other notices and demands to which the Borrower
      would otherwise be entitled. Each Borrower waives any defense arising from
      any
      defense of any other Borrower, or by reason of the cessation from any cause
      whatsoever of the liability of any other Borrower. Bank’s failure at any time to
      require strict performance by any Borrower of any provision of the Loan
      Documents shall not waive, alter or diminish any right of Bank thereafter to
      demand strict compliance and performance therewith. Nothing contained herein
      shall prevent Bank from foreclosing on the Lien of any deed of trust, mortgage
      or other security instrument, or exercising any rights available thereunder,
      and
      the exercise of any such rights shall not constitute a legal or equitable
      discharge of any Borrower. Each Borrower also waives any defense arising from
      any act or omission of Bank that changes the scope of the Borrower’s risks
      hereunder. 

     

    13.6  Subrogation
      Defenses.
      Each
      Borrower hereby waives any defense based on impairment or destruction of its
      subrogation or other rights against any other Borrower and waives all benefits
      which might otherwise be available to it under California Civil Code Sections
      2809, 2810, 2819, 2839, 2845, 2848, 2849, 2850, 2899, and 3433 and California
      Code of Civil Procedure Sections 580a, 580b, 580d and 726, as those statutory
      provisions are now in effect and hereafter amended, and under any other similar

    Rapiscan
      Systems (OSI)

    Arbitration
      with former owners of Accurel Systems 

    

    From
      time
      to time, we are subject to various claims, legal proceedings and investigations
      covering a wide range of matters that arise in the ordinary course of our
      business activities. Each of these matters is subject to various uncertainties.
      

    

    On
      or
      about March 8, 2006, the Company commenced an arbitration under the Rules of
      the
      American Arbitration Association against Respondents Majid Ghafghaichi (“Majid”)
      and Vahe Sarkissisian (“Vahe”), seeking a total of $3,994,000 for
      indemnification of various “Losses,” as defined in, and expressly allowed
      pursuant to, a Stock Purchase Agreement dated March 9, 2005 (the “Agreement”),
      between the Company, as the purchaser, Accurel Systems International Corporation
      (“Accurel), and  Majid and Vahe, as the sellers of 100% of the issued and
      outstanding shares of Accurel stock. 

    

    More
      specifically, there are four claims asserted by the Company against Respondents:
      (1) Damages of $3.4 million resulting from misrepresentations concerning the
      loss of business from a key Accurel customer; (2) unauthorized withdrawals
      in
      the amount of approximately $276,000 from Accurel by the Respondents prior
      to
      the closing; (3) approximately $49,000 of disallowed transaction expenses that
      the Respondents improperly received; and (4) undisclosed net liabilities
      totaling approximately $269,000.    

    

    Respondents
      have asserted counterclaims seeking “an aggregate amount in excess of
      $1,750,000,” based on the allegedly “late payment” to Respondents of Company
      stock and a Secured Promissory Note as part of the consideration for their
      sale
      of Accurel stock.  The Company has filed a detailed denial of all
      counterclaims.

    

    The
      arbitration is now in the discovery phase, and the hearing is scheduled for
      February 2007.

    

    At
      this
      early stage of the proceedings, particularly before the commencement of
      depositions, it is difficult to assess the final outcome of this arbitration.
      However, the Company believes that the counterclaims have no merit, and will
      vigorously defend itself against such counterclaims.

    

    On
      March
      23, 2005, we entered into a Development, Distribution and Manufacturing
      Agreement (the “Rapiscan Agreement”) with Rapiscan Systems, Inc.
      (“Rapiscan”).  Under the terms of this agreement, we gave Rapiscan the
      exclusive worldwide rights to market our Quantum SnifferTM portable
      and benchtop trace detection devices under their private label.  We also
      agreed to give Rapiscan the exclusive worldwide rights to distribute certain
      other new security products which we may develop in the future with their
      funding, as well as rights, in some circumstances, to manufacture certain
      components of the Quantum SnifferTM portable
      and benchtop trace detection devices that they are able to sell. 

    

    On
      March
      24, 2006, the Company brought suit in the United States District Court in the
      District of Massachusetts against Rapiscan and its parent, OSI Systems, Inc.
      (“OSI”). The Company is requesting rescission of the Rapiscan Agreement, for
      lack of performance and other grounds. In the alternative, the Company is
      seeking termination of the Rapiscan Agreement due to material breaches of
      contract and implied covenant of good faith and fair dealing and for damages
      due
      to Rapiscan’s breach of contract and the implied covenant of good faith and fair
      dealing. 

    

    On
      March
      27, 2006, the Company received notice that Rapiscan filed a complaint against
      the Company and its contract manufacturer, Columbia Tech, in the United States
      District Court for the Central District of California, regarding the Rapiscan
      Agreement. Rapiscan’s complaint against the Company is based upon claims of
      breach of contract and breach of warranty and is requesting a decree for
      specific performance, declaratory relief and injunctive relief. Rapiscan’s
      complaint against Columbia Tech is based upon injunctive relief, declaratory
      relief and tortuous interference with contractual relations. On April 12, 2006,
      Rapiscan dismissed all claims against Columbia Tech. 

    

    As
      of
      August 18, 2006, as a result of motions made by both parties, the two lawsuits
      have been consolidated in the United States District Court for the Central
      District of California with the Company as plaintiff. Presently, discovery
      is in
      process. Rapiscan and OSI have filed a motion to dismiss certain of the
      Company’s claims. As of October 30, 2006, the court has ruled that the Company’s
      claim of breach of fiduciary duty was dismissed but OSI’s motion to dismiss all
      other claims was denied. 

     

    Should
      the Company be unsuccessful in prosecuting this matter, it may have a material
      adverse effect on its business and results of operations. No revenue has been
      recorded related to the Rapiscan Agreement.

     

    We
      may,
      from time to time, be involved in other actual or potential proceedings that
      we
      consider to be in the normal course of our business. We do not believe that
      any
      of these proceedings will have a material adverse effect on our
      business.
