                                IMPERIAL BANK
                                 Member FDIC

                          SECURITY AND LOAN AGREEMENT
                             (ACCOUNTS RECEIVABLE)

This Agreement is entered into between    IDENTIX INCORPORATED
                                          , a     Corporation

(herein called "Borrower") and IMPERIAL BANK (herein called "Bank").

1. Bank hereby commits, subject to all the terms and conditions of this 
   Agreement and prior to the termination of its commitment as hereinafter
   provided, to make loans to Borrower from time to time in such amounts as
   may be determined by Bank up to, but not exceeding in the aggregate unpaid
   principal balance, the following Borrowing Base:

                        80.000% of Eligible Accounts

   and in no event more than $5,000,000.00

2. The amount of each loan made by Bank to Borrower hereunder shall be debited
   to the loan ledger account of Borrower maintained by Bank (herein called
   "Loan Account") and Bank shall credit the Loan Account with all loan 
   repayments made by Borrower. Borrower promises to pay Bank (a) the unpaid
   balance of Borrower's Loan Account on demand and (b) on or before the tenth
   day of each month, interest on the average daily unpaid balance of the Loan
   Account during the immediately preceding month at the rate of NO percent
   (0.000%) per annum in excess of the rate of interest which Bank has 
   announced as its prime lending rate ("Prime Rate") which shall vary 
   concurrently with any change in such Prime Rate. Interest shall be computed
   at the above rate on the basis of the actual number of days during which the
   principal balance of the loan account is outstanding divided by 360, which
   shall for interest computation purposes be considered one year. Bank at its
   option may demand payment of any or all of the amount due under the Loan
   Account including accrued but unpaid interest at any time. Such notice may 
   be given verbally or in writing and should be effective upon receipt by 
   Borrower. The amount of interest payable each month by Borrower shall not 
   be less than a minimum monthly charge of $250.00. Bank is hereby authorized 
   to charge Borrower's deposit account(s) with Bank for all sums due Bank under
   this Agreement.

3. Requests for loans hereunder shall be in writing duly executed by Borrower in
   a form satisfactory to Bank and shall contain a certification setting forth
   the matters referred to in Section 1, which shall disclose that Borrower is
   entitled to the amount of loan being requested.

4. As used in this Agreement, the following terms shall have the following
   meanings:

   A.  "Accounts" means any right to payment for goods sold or leased, or to be
       sold or to be leased, or for services rendered or to be rendered no 
       matter how evidenced, including accounts receivable, contract rights,
       chattel paper, instruments, purchase orders, notes, drafts, acceptances,
       general intangibles and other forms of obligations and receivables.

   B.  "Collateral" means any and all personal property of Borrower which is
       assigned or hereafter is assigned to Bank as security or in which Bank
       now has or hereafter acquires a security interest. 

   C.  "Eligible Accounts" means all of Borrower's Accounts excluding,
       however, (1) all Accounts under which payment is not received within 90
       days from any invoice date, (2) all Accounts against which the account
       debtor or any other person obligated to make payment thereon asserts any
       defense, offset, counterclaim or other right to avoid or reduce the
       liability represented by the Account and (3) any Accounts if the account
       debtor or any other person liable in connection therewith is insolvent,
       subject to bankruptcy or receivership proceedings or has made an
       assignment for the benefit of creditors or whose credit standing is
       unacceptable to Bank and Bank has so notified Borrower. Eligible Accounts
       shall only include such accounts as Bank in its sole discretion shall
       determine are eligible from time to time.

5. Borrower hereby assigns to Bank all Borrower's present and future Accounts,
   including all proceeds due thereunder, all guaranties and security therefor,
   and hereby grants to Bank a continuing security interest in all moneys in the
   Collateral Account referred to in Section 6 hereof, as security for any and
   all obligations of Borrower to Bank, whether now owing or hereafter incurred
   and whether direct, indirect, absolute or contingent. So long as Borrower is
   indebted to Bank or Bank is committed to extend credit to Borrower, Borrower
   will execute and deliver to Bank such assignments, including Bank's standard
   forms of Specific or General Assignment covering individual Accounts, 
   notices, financing statements, and other documents and papers as Bank may 
   require in order to affirm, effectuate or further assure the assignment to
   Bank of the Collateral or to give any third party, including the account
   debtors obligated on the Accounts, notice of Bank's interest in the 
   Collateral.

6. Until Bank exercises its rights to collect the Accounts pursuant to 
   paragraph 10, Borrower will collect with diligence all Borrower's Accounts,
   provided that no legal action shall be maintained thereon or in connection
   therewith without Bank's prior written consent. Any collection of Accounts by
   Borrower, whether in the form of cash, checks, notes, or other instruments 
   for the payment of money (properly endorsed or assigned where required to
   enable Bank to collect same), shall be in trust for Bank, and Borrower
   shall keep all such collections separate and apart from all other funds and
   property so as to be capable of identification as the property of Bank and
   deliver said collections daily to Bank in the identical form received. The
   proceeds of such collections when received by Bank may be applied by Bank
   directly to the payment of Borrower's Loan Account or any other obligation
   secured hereby. Any credit given by Bank upon receipt of said proceeds shall
   be conditional credit subject to collection. Returned items at Bank's option
   may be charged to Borrower's general account. All collections of the Accounts
   shall be set forth on an itemized schedule, showing the name of the account
   debtor, the amount of each payment and such other information as Bank may
   request.

7. Until Bank exercises its rights to collect the Accounts pursuant to 
   paragraph 10, Borrower may continue its present policies with respect to 
   returned merchandise and adjustments. However, Borrower shall immediately
   notify Bank of all cases involving returns, repossessions, and loss or damage
   of or to merchandise represented by the Accounts and of any credits, 
   adjustments or disputes arising in connection with the goods or services
   represented by the Accounts and, in any of such events, Borrower will
   immediately pay to Bank from its own funds (and not from the proceeds of 
   Accounts or Inventory) for application to Borrower's Loan Account or any
   other obligation secured hereby the amount of any credit for such returned
   or repossessed merchandise and adjustments made to any of the Accounts.

8. Borrower represents and warrants to Bank: (i) If Borrower is a corporation,
   that Borrower is duly organized and existing in the State of its 
   incorporation and the execution, delivery and performance hereof are within
   Borrower's corporate powers, have been duly authorized and are not in 
   conflict with law or the terms of any charter, by-law or other incorporation 
   papers, or of any indenture, agreement or undertaking to which Borrower is a
   party or by which Borrower is found or affected; (ii) Borrower is, or at the
   time the collateral becomes subject to Bank's security interest will be, the
   true and lawful owner of and has, or at the time the collateral becomes
   subject to Bank's security interest will have, good and clear title to the
   Collateral, subject only to Bank's rights therein; (iii) Each Account is, or
   at the time the Account comes into existence will be, a true and correct
   statement of a bona fide indebtedness incurred by the debtor named therein in
   the amount of the Account for either merchandise sold or delivered (or being 
   held subject to Borrower's delivery instructions) to, or services rendered,
   performed and accepted by, the account debtor; (iv) That there are or will be
   no defenses, counterclaims, or setoffs which may be asserted against the
   Accounts; and (v) any and all financial information, including information
   relating to the Collateral submitted by Borrower to Bank, whether previously
   or in the future, is or will be true and correct.  
<PAGE>   2
 9.  Borrower will: (i) Furnish Bank from time to time such financial
     statements and information as Bank may reasonably request and inform Bank
     immediately upon the occurrence of a material adverse change therein; (ii)
     Furnish Bank periodically, in such form and detail and at such times as
     Bank may require, statements showing aging and reconciliation of the
     Accounts and collections thereon; (iii) Permit representatives of Bank to
     inspect the Borrower's books and records relating to the Collateral and
     make extracts therefrom at any reasonable time and to arrange for
     verification of the Accounts, under reasonable procedures, acceptable to
     Bank, directly with the account debtors or otherwise at Borrower's expense;
     (iv) Promptly notify Bank of any attachment or other legal process levied
     against any of the Collateral and any information received by Borrower
     relative to the Collateral, including the Accounts, the account debtors or
     other persons obligated in connection therewith, which may in any way
     affect the value of the Collateral or the rights and remedies of Bank in
     respect thereto; (v) Reimburse Bank upon demand for any and all legal
     costs, including reasonable attorneys' fees, and other expense incurred in
     collecting any sums payable by Borrower under Borrower's Loan Account or
     any other obligation secured hereby, enforcing any term or provision of
     this Security Agreement or otherwise or in the checking, handling and
     collection of the Collateral and the preparation and enforcement of any
     agreement relating thereto; (vi) Notify Bank of each location and of each
     office of Borrower at which records of Borrower relating to the Accounts
     are kept; (vii) Provide, maintain and deliver to Bank policies insuring the
     Collateral against loss or damage by such risks and in such amounts, forms
     and companies as Bank may require and with loss payable solely to Bank,
     and, in the event Bank takes possession of the Collateral, the insurance
     policy or policies and any unearned or returned premium thereon shall at
     the option of Bank become the sole property of Bank, such policies and the
     proceeds of any other insurance covering or in any way relating to the
     Collateral, whether now in existence or hereafter obtained, being hereby
     assigned to Bank; and (viii) in the event the unpaid balance of Borrower's
     Loan Account shall exceed the maximum amount of outstanding loans to which
     Borrower is entitled under Section 1 hereof, Borrower shall immediately pay
     to Bank, from its own funds and not from the proceeds of Collateral, for
     credit to Borrower's Loan Account the amount of such excess.

10. Bank may at any time, without prior notice to Borrower, collect the Accounts
    and may give notice of assignment to any and all account debtors, and
    Borrower does hereby make, constitute and appoint Bank its irrevocable, true
    and lawful attorney with power to receive, open and dispose of all mail
    addressed to Borrower, to endorse the name of Borrower upon any checks or
    other evidences of payment that may come into the possession of Bank upon
    the Accounts to endorse the name of the undersigned upon any document or
    instrument relating to the Collateral; In its name or otherwise, to demand,
    sue for, collect and give acquittances for any and all moneys due or to
    become due upon the Accounts; to compromise, prosecute or defend any action,
    claim or proceeding with respect thereto; and to do any and all things
    necessary and proper to carry out the purpose herein contemplated.

11. Until Borrower's Loan Account and all other obligations secured hereby
    shall have been repaid in full, Borrower shall not sell, dispose of or grant
    a security interest in any of the Collateral other than to Bank, or execute
    any financing statements covering the Collateral in favor of any secured
    party or person other than Bank.

12. Should: (i) Default be made in the payment of any obligation, or breach be
    made in any warranty, statement, promise, term or condition, contained
    herein or hereby secured; (ii) Any statement or representation made for the
    purpose of obtaining credit hereunder prove false; (iii) Bank deem the
    Collateral inadequate or unsafe or in danger of misuse; (iv) Borrower become
    insolvent or make an assignment for the benefit of creditors; or (v) Any
    proceeding be commended by or against Borrower under any bankruptcy,
    reorganization, arrangement, readjustment of debt or moratorium law or
    statute; then in any such event, Bank may, at its option and without demand
    first made and without notice to Borrower, do any one or more of the
    following: (a) Terminate its obligation to make loans to Borrower as
    provided in Section 1 hereof; (b) Declare all sums secured hereby
    immediately due and payable; (c) immediately take possession of the
    Collateral wherever it may be found, using all necessary force so to do, or
    require Borrower to assemble the Collateral and make it available to Bank at
    a place designated by Bank which is reasonably convenient to Borrower and
    Bank, and Borrower waives all claims for damages due to or arising from or
    connected with any such taking; (d) Proceed in the foreclosure of Bank's
    security interest and sale of the Collateral in any manner permitted by
    law, or provided for herein; (e) Sell, lease or otherwise dispose of the
    Collateral at public or private sale, with or without having the Collateral
    at the place of sale, and upon terms and in such manner as Bank may
    determine, and Bank may purchase same at any such sale; (f) Retain the
    Collateral in full satisfaction of the obligations secured thereby; (g) 
    Exercise any remedies of a secured party under the Uniform Commercial Code.
    Prior to any such disposition, Bank may, at its option, cause any of the
    Collateral to be repaired or reconditioned in such manner and to such extent
    as Bank may deem advisable, and any sums expended therefor by Bank shall be
    repaid by Borrower and secured hereby. Bank shall have the right to enforce
    one or more remedies hereunder successively or concurrently, and any such
    action shall not estop or prevent Bank from pursuing any further remedy 
    which it may have hereunder or by law. If a sufficient sum is not realized 
    from any such disposition of Collateral to pay all obligations secured by 
    this Security Agreement, Borrower hereby promises and agrees to pay Bank any
    deficiency.

13. If any writ of attachment, garnishment, execution or other legal process be
    issued against any property of Borrower, or if any assessment for taxes
    against Borrower, other than real property, is made by the Federal or State
    government or any department thereof, the obligation of Bank to make loans
    to Borrower as provided in Section 1 hereof shall immediately terminate and
    the unpaid balance of the Loan Account, all other obligations secured hereby
    and all other sums due hereunder shall immediately become due and payable
    without demand, presentment or notice.

14. Borrower authorizes Bank to destroy all invoices, delivery receipts, reports
    and other types of documents and records submitted to Bank in connection
    with the transactions contemplated herein at any time subsequent to four
    months from the time such items are delivered to Bank.

15. Nothing herein shall in any way limit the effect of the conditions set forth
    in any other security or other agreement executed by Borrower, but each and
    every condition hereof shall be in addition thereto.

16. Additional Provisions: Subject to conditions and limitations contained in 
    the Letter Agreement dated September 27, 1996 (and accepted and agreed to
    10/1/96) and Credit Terms and Conditions dated October 4, 1996. See Addendum

Subject: Credit Terms and Conditions    Borrower: Identix Incorporated
         ("Agreement")      

Gentlemen:

To induce you to make loans to the undersigned (herein called "Borrower"), and

        2. AGREEMENT AUTHORIZED. The execution, delivery and performance of
this Agreement are duly authorized and do not require the consent or approval
of any governmental body or other regulatory authority; are not in
contravention of or in conflict with any law or regulation or any term or
provision of Borrower's articles of incorporation, by-laws, or Articles of
Association, as the case may be, and this Agreement is the valid, binding and
legally enforceable obligation of Borrower in accordance with its terms.

        3. NO CONFLICT. The execution, delivery and performance of this
Agreement are not in contravention of or in conflict with any agreement,
indenture or undertaking to which Borrower is a party or by which it or any of

statements and data submitted in writing by Borrower to you in connection with
this request for credit are true and correct, and said balance sheet and profit
and loss statement truly present the financial condition of Borrower as of the
date thereof and the results of the operations of Borrower for the period
covered thereby, and have been prepared in accordance with generally accepted

of Borrower. Borrower has no knowledge of any liabilities, contingent or
otherwise, at such date not reflected in said balance sheet, and Borrower has
