                        SEPARATION AGREEMENT AND RELEASE

        This Separation Agreement and Release (the "Agreement") is entered into
by and between Identix Incorporated ("Identix") and James P. Scullion
("Employee") (collectively, "the Parties").

                                    RECITALS

        A. Employee is currently employed by Identix on the terms provided in a
Compensation Continuation Agreement dated January 5, 2000, as amended on August
22, 2001 and on January 29, 2002 (as so amended, the "Original Agreement").
Identix has entered into an Agreement and Plan of Merger dated February 22,
2002, by and among Identix, Visionics Corporation and Viper Acquisition
Corporation to effect the merger of Viper Acquisition Corp., a wholly owned
subsidiary of the Company, with and into Visionics Corporation (the "Merger").
In the event the Merger does not occur, the terms of the Original Agreement
shall remain in full force and effect, and this Agreement shall have no force or
effect.

        B. Identix and Employee have agreed that, should the Merger occur, (i)
Employee shall voluntarily resign his employment and positions on the Board of
Directors of Identix, its subsidiaries, joint ventures and affiliates, and
Employee's employment relationship and Board positions shall terminate, as of
the date set forth herein, (ii) the payments and benefits described below shall
be provided, and (iii) Employee and Identix shall release each other from any
claims as provided below.

                                    AGREEMENT

        WHEREFORE, contingent upon the occurrence of the Merger, the Parties
agree as follows:

1.      Employee hereby resigns his employment with Identix effective on the
        consummation of the Merger ("the Termination Date"). Employee also
        hereby resigns as an officer and as a Director of Identix and as a
        Director of any and all subsidiaries, joint ventures and affiliates of
        Identix, effective on the Termination Date.

2.      Identix shall make the following payments to Employee, contingent upon
        his compliance with his undertakings under this Agreement: (a) on the
        Termination Date, the gross sum of $280,000.00, in a lump sum, less all
        appropriate taxes, withholdings and deductions, shall be paid by Identix
        to Employee; or, in the alternative (but not in addition) to this lump
        sum payment, Employee, at his option, may elect to be paid 12 months of
        salary continuation at his current gross bi-weekly base salary rate of
        $10,769.23, less all appropriate taxes, withholdings and deductions, on
        Identix' customary payroll dates over the 12 month period following the
        Termination Date (which is equivalent to $280,000 in the aggregate);
        provided, however, that Employee will be deemed to have elected the
        salary continuation option rather than the lump sum option unless
        Identix has received written notice from Employee at least ten business
        days prior to the Termination Date that Employee has elected the lump
        sum option; and (b) within ten business days after the one year
        anniversary of the Termination Date, the gross sum of $140,000.00, in a
        lump sum, less all appropriate taxes, withholdings and deductions, shall
        be paid by Identix to Employee. On the Termination Date, Employee shall
        pay to Identix in immediately available funds the amount of $30,000.00,
        which constitutes repayment of an advance previously made to Employee by
        Identix. Employee shall submit appropriate

<PAGE>

        documentation for reimbursement of outstanding business expenses no
        later than two weeks prior to the Termination Date, and Identix shall
        pay on or before the Termination Date all reasonable, documented and
        appropriate business expenses so submitted pursuant to the expense
        reimbursement policies of Identix.

3.      Employee and his dependents shall receive medical and dental insurance
        coverage provided they are and remain eligible under COBRA, and Identix
        shall pay all required COBRA premiums for 12 months following the
        Termination Date.

4.      Identix shall make payments to continue Employee's term life insurance
        (or pay Employee an amount equivalent to the premiums in effect prior to
        the Termination Date, at Employee's option) for 12 months following the
        Termination Date.

5.      The options to purchase Common Stock granted to Employee by Identix
        identified on Attachment A hereto, which Employee agrees and
        acknowledges are all of the options to which Employee is entitled, shall
        fully vest on the Termination Date, and notwithstanding any provision of
        any relevant stock option agreement or stock option plan to the
        contrary, Employee shall have 12 months from the Termination Date to
        exercise such options.

6.

        6.1  Prior to or on the Termination Date, Identix shall pay to Employee
               all regular salary earned, bonuses accrued, car allowance, and
               payment for all accrued and unused vacation through the
               Termination Date, less all appropriate taxes, withholdings and
               deductions. Employee acknowledges that, except as provided
               herein, Employee shall receive no payments, wages, bonuses or
               benefits from Identix after the Termination Date.

        6.2  Prior to the Termination Date, Identix shall pay to Employee the
               amount of the actual attorneys' fees and costs of Morrison &
               Foerster LLP, not to exceed $12,500, incurred by Employee in
               connection with his employment relationship with Identix and his
               separation of employment pursuant to this Agreement.

7.      Subject to payment and provision of the consideration described above,
        Employee, for himself and for each of his representatives, heirs,
        successors and assigns, does hereby release, acquit and forever
        discharge Identix and Visionics Corporation and its and their respective
        parent companies, affiliates, subsidiaries, divisions and related
        companies, and its and their past, present and future employees, agents,
        attorneys, officers, directors, shareholders, partners, heirs,
        executors, administrators, insurers, successors and assigns (all
        hereinafter "Releasees") from and against any and all claims, rights,
        demands, actions, obligations, liabilities and causes of action, whether
        asserted or unasserted, of any and every kind, nature and character
        whatsoever, that he may now have or has ever had against Releasees, or
        any of them, including those related to the termination of employment,
        the prior lack of such employment, or any claims of discrimination,
        harassment or retaliation, including but not limited to claims arising
        under Title VII of the Civil Rights Act of 1964, the Age Discrimination
        in Employment Act of 1967, the Americans with Disabilities Act, the
        California Fair Employment and Housing Act and any claims arising under
        any federal, state or local law, and all claims based upon acts or
        omissions of Releasees, or any of them, whatsoever occurring or arising
        up to and including the Termination Date.

                                       2

        7.1  Employee understands and agrees that this Agreement is a full and
               final release covering all known and unknown and unanticipated
               injuries, debts, claims or damages to him that have arisen or may
               have arisen from any matters, acts, omissions or dealings
               released in Paragraph 7. Therefore, as to these matters released
               above, Employee hereby expressly waives and relinquishes any and
               all rights or benefits that he may now have, or in the future may
               have under the terms of California Civil Code Section 1542 and
               any similar law of any state or territory of the United States.
               Said section provides as follows:

                      "A general release does not extend to claims which the
                      creditor does not know or suspect to exist in his favor at
                      the time of executing the release, which if known by his
                      must have materially affected his settlement with the
                      debtor."

               Employee acknowledges that he is aware that he may hereafter
               discover facts in addition to, or different from, those which he
               now knows or believes to be true, but it is his intention hereby,
               fully and finally and forever, to settle and to release any and
               all matters, disputes and differences, known or unknown,
               suspected or unsuspected, that do now exist, may exist or
               heretofore have existed with respect to those matters described
               in Paragraph 7.

        7.2  Notwithstanding the foregoing general language, the parties agree
               that the release of claims against Identix shall not extend to
               breaches of this Agreement by Identix, and the parties further
               agree that any rights of indemnification Employee has with regard
               to Releasees or any of them, whether under virtue of his acts or
               omissions, his capacity as a current or former director, officer
               or employee of Identix, or whether pursuant to contract
               (including but not limited to the Indemnification Agreement
               entered into as of July 26, 1996 between Identix and Employee,
               Attachment B hereto), statute, common law, or Identix'
               Certificate of Incorporation or by-laws, or whether under any
               policy of insurance issued to or for the benefit of Identix, its
               officers or directors, are not affected by this Release.

        7.3  Employee represents and agrees that he has not filed and, except as
               otherwise provided by law, will not file, refile, or prosecute
               any claim, charge, grievance, complaint or action for monetary
               damages, before any local, state or federal court, arbitrator, or
               administrative agency, board or tribunal concerning any matter
               which was or could have been raised in connection with any matter
               released in this Paragraph 7. Employee agrees that he will not
               knowingly apply or reapply for employment with Identix or any of
               its affiliates.

8.      Identix, on behalf of itself and, to the extent permitted by law, its
        subsidiaries, affiliates, parent corporations or successors and, with
        regard to derivative claims only, its past and present directors,
        officers, general limited partners, agents and representatives, hereby
        agrees to release and forever discharge Employee and his executors,
        heirs, representatives and assigns, from any and all claims, debts,
        demands, accounts, judgments, rights, cause of action, equitable relief,
        damages, costs, charges, complaints, obligations, promises, agreements,
        controversies, suits, expenses, compensation, responsibility and
        liability of every kind and character whatsoever, whether in law or
        equity, based on any events or circumstances arising or occurring prior
        to the Termination Date.

                                       3

        8.1  Identix understands and agrees that this Agreement is a full and
               final release covering all known and unknown and unanticipated
               injuries, debts, claims or damages that have arisen or may have
               arisen to it from any matters, acts, omissions or dealings
               released in Paragraph 8. Therefore, as to these matters released
               above, and except as provided in Paragraph 8.2 below, Identix
               hereby expressly waives and relinquishes any and all rights or
               benefits it may now have, or in the future may have under the
               terms of California Civil Code Section 1542 and any similar law
               of any state or territory of the United States. Said section
               provides as follows:

                      "A general release does not extend to claims which the
                      creditor does not know or suspect to exist in his favor at
                      the time of executing the release, which if known by his
                      must have materially affected his settlement with the
                      debtor."

               Identix acknowledges that it may hereafter discover facts in
               addition to, or different from, those which it now knows or
               believes to be true, but intends hereby, fully and finally and
               forever, to settle and to release any and all matters, disputes
               and differences, known or unknown, suspected or unsuspected, that
               do now exist, may exist or heretofore have existed with respect
               to those matters described in Paragraph 8.

        8.2  Notwithstanding the foregoing general language, the parties agree
               that the release of claims against Employee shall extend only to
               matters with regard to which Employee acted in good faith and in
               a manner he reasonably believed to be in, or not opposed to,
               Identix' best interests, shall not extend to matters with regard
               to which Employee acted with willful misconduct, and further
               shall not extend to breaches of this Agreement by Employee.

9.      Also in consideration for the payments, benefits and undertakings
        provided above, Employee and Identix agree that the existence of,
        reasons for and terms of this Agreement will be held in the strictest
        confidence and will not be disclosed, directly or indirectly, to any
        person or entity, including but not limited to past, current or future
        Identix employees; provided, however, that Identix may disclose
        information that already has become public, on a "need to know" basis to
        its employees and outside the company, to regulatory agencies, as
        required by law, and to its tax advisors and attorneys, and may in a
        press release disclose that Employee's employment with Identix will
        cease as of the Merger; and further provided that Employee may disclose
        information that has already become public, and may disclose the
        financial terms of this Agreement as required by law and to his tax
        advisors and attorneys, on the condition that they agree to hold those
        terms in strictest confidence, and that Employee agrees to accept
        responsibility for any breach of confidentiality by those individuals.
        Employee specifically agrees that he will not otherwise disclose that he
        has received the payments or benefits described in this Agreement or
        that he received from Releasees any payment, money, compensation,
        property or expense reimbursement in any form or sum whatsoever under
        the terms of this Agreement. The obligations of Identix and Employee
        under this Agreement are contingent on the other party's compliance with
        this confidentiality provision as well as all of such other party's
        other obligations under this Agreement.

10.     Payment of all benefits hereunder shall be contingent on Employee (i)
        not soliciting for hire, directly or indirectly, on behalf of himself or
        any third party, for one year after the

                                       4
<PAGE>

        Termination Date, (a) any contractors, consultants or subcontractors of
        Identix, or their employees, or (b) any employees of Identix, (ii)
        continuing to comply with all provisions of this Agreement and the
        Identix Proprietary Information and Inventions Agreement signed by
        Employee on September 10, 1990, a copy of which is attached hereto as
        Attachment C, to the extent not inconsistent with this Agreement, and
        (iii) not making disparaging statements regarding Releasees or any of
        them, including but not limited to statements regarding management of
        the Company or the circumstances surrounding Employee's departure from
        Identix. Employee agrees that this is a material provision of the
        Agreement. Identix agrees that its officers and directors shall not make
        disparaging statements regarding Employee.

11.     This Agreement is binding on and for the benefit of Employee and
        Releasees, and their respective heirs executors, administrators,
        successors and assigns, wherever the context requires or admits.

12.     Employee declares that prior to the execution of this Agreement, he
        apprised himself of sufficient relevant information, through sources of
        his own selection, in order that he might intelligently exercise his own
        judgment in deciding whether to execute it, and in deciding on the
        contents hereof. Employee further declares that this decision is not
        predicated on or influenced by any declarations or representations of
        the persons or entities released or any predecessors in interest,
        successors, assigns, officers, directors, Employee, attorneys, or agents
        of said entities other than as may be contained in this instrument.

13.     Employee expressly states that he has read this Agreement and
        understands all of its terms and that all agreements and understandings
        between the parties are embodied and expressed herein. This Agreement is
        executed voluntarily and with full knowledge of its significance.

14.     If any provision or portion of this Agreement shall be adjudged by a
        court to be void or unenforceable, the same shall in no way affect any
        other provision of this Agreement, the application of such provision in
        any other circumstances, or the validity or enforceability of this
        Agreement.

15.     This instrument contains the entire agreement of the parties with regard
        to matters covered in it, and supersedes any prior agreements as to
        those matters, with the exception of (a) the Indemnification Agreement
        entered into as of July 26, 1996 between Identix and Employee,
        Attachment B hereto, and (b) the Proprietary Information and Inventions
        Agreement dated September 10, 1990, Attachment C hereto, both of which
        agreements remain in full force and effect to the extent not
        inconsistent with this Agreement. This Agreement may not be changed or
        modified, in whole or in part, except by an instrument in writing signed
        by Employee and an officer of Identix.

16.     Employee expressly states that he has been given 21 days in which to
        consider whether to enter into this Agreement and that he has consulted
        with an attorney. This Agreement does not become effective until 7 days
        after its execution. Employee understands that he may revoke this
        Agreement at any time during the 7 days after its execution. It is
        agreed that any such revocation must be received in writing by Identix'
        Chief Executive Officer within said 7-day period in order to be
        effective. All time limits refer to calendar days unless otherwise
        specified.

               March 1, 2005 through September 30, 2005      $9,834.54 per month

Basic Rent for any partial calendar months at the beginning or end of the
Sublease Term shall be prorated on a daily basis. Subtenant acknowledges that
Sublandlord's payments of Basic Rent for the Original Premises are paid to Prime
Landlord on the first day of each calendar month during the Term and Subtenant
therefore covenants and agrees that its payments of Basic Rent hereunder shall
be paid to Sublandlord at least two (2) business days prior to the first of each
calendar month. Subtenant shall deliver $9,000.00 as payment for the first
month's rent upon execution of this Sublease.

         VII.  ACCESS SYSTEM. Subtenant shall pay to Sublandlord as additional
rent a monthly fee of Two Hundred Twenty Five and 00/100 Dollars ($225.00) for
the use of the ADT Card Entry System (the "ADT System") currently in place at
the Subleased Premises. This fee shall cover the initial set up of the system
and normal monitoring. Subtenant shall buy from Sublandlord access cards for
Subtenant's employees at a charge of Nine and 00/100 Dollars ($9.00) per card.
Replacement cards shall be charged at the same rate as new cards. Subtenant
shall also pay to Sublandlord as additional rent the costs for any additional
administration of the ADT System by Sublandlord at the rate of Seventy and
00/100 Dollars ($70.00) per hour.

         VIII. USE. The Subleased Premises shall be used and occupied for
general business office purposes and for no other use or purpose.

         IX. SECURITY DEPOSIT. Upon execution hereof, Subtenant has delivered to
Sublandlord the sum of $9,000.00 (one (1) month of Basic Rent) ("Subtenant's
Security Deposit"), such sum to be held by Sublandlord as security for the
performance of Subtenant's obligations under this Sublease. Upon the occurrence
of any default by Subtenant hereunder after expiration of any applicable grace
or cure periods, Subtenant agrees that Sublandlord may apply all or any part of
Subtenant's Security Deposit, together with accrued interest, if any, to any
obligation of Subtenant hereunder. Such application shall not excuse the default
of Subtenant hereunder. If all or any portion of Subtenant's

                                      -2-
<PAGE>

Security Deposit is applied by Sublandlord against any of Subtenant's
obligations hereunder, Subtenant shall promptly restore Subtenant's Security
Deposit to its original amount. Interest on Subtenant's Security Deposit shall
in all instances be retained by Sublandlord. Subtenant's Security Deposit will
be returned to Subtenant within thirty (30) days of termination of this
Sublease.

         X.   PRIME LEASE. Subtenant agrees that it will do nothing in, on or
about the Subleased Premises which would result in the breach by Sublandlord of
its undertakings and obligations under the Prime Lease. Except for the following
provisions, this Sublease shall be subject to and on all of the terms and
conditions as are contained in the Prime Lease and the provisions of the Prime
Lease are hereby incorporated into this Sublease as if Sublandlord were the
landlord thereunder and Subtenant the tenant thereunder:

         The defined economic terms for "Basic Rent," "Security Deposit,"
"Tenant Allowance," "Term," "Premises" and the like are inapplicable;

              A.     Section 3.2 of the Prime Lease (relating to escalation
                     payments) are inapplicable;

              B.     Section 31 of the Prime Lease (relating to brokers) is
                     inapplicable;

              C.     Exhibit B to the Prime Lease (relating to construction of
                     the Original Premises) is inapplicable.

         Where appropriate, references to "Landlord" in the Prime Lease shall be
deemed to mean "Sublandlord" hereunder and references to "Tenant" in the Prime
Lease shall be deemed to mean "Subtenant" hereunder, it being understood and
agreed that Sublandlord will not be acting as, or assuming any of the
responsibilities of, Prime Landlord, and all references in the Prime Lease to
Landlord-provided services or Landlord insurance requirements, and any other
references which by their nature relate to the owner or operator of the
Building, rather than to a tenant of the Building subleasing space to a
subtenant, shall continue to be references to Prime Landlord and not to
Sublandlord.

         XI.  SUBTENANT'S COVENANTS. Subtenant covenants to Sublandlord to
perform all of the covenants and obligations to be performed by Sublandlord as
Tenant under the Prime Lease as the same relate to the Subleased Premises and to
comply with this Sublease and the applicable provisions of the Prime Lease, as
modified by this Sublease, in all respects. If Subtenant shall fail to make any
payment or perform any act required to be made or performed by Subtenant under
the Prime Lease pursuant to Subtenant's assumption of Sublandlord's obligations
thereunder as they relate to the Subleased Premises, and such default is not
cured by Subtenant by the first to occur of (i) one-half of the period specified
in the Prime Lease for curing such default, or (ii) five (5) days prior to the
expiration of such Prime Lease cure period, Sublandlord, without waiving or
releasing any obligation or default hereunder, may (but shall be under no
obligation to) make such payment or perform such act for the account and at the
expense of Subtenant, and may take any and all such actions as Sublandlord in
its sole discretion deems necessary or appropriate to accomplish such cure. If
Sublandlord shall reasonably incur any expense in remedying such default,
Sublandlord shall be entitled to recover such sums upon demand from Subtenant as
Additional Rent under this Sublease.

         XII.   SUBLANDLORD'S COVENANTS. Sublandlord covenants to Subtenant to
perform all of the terms and provisions required of it under the Prime Lease and
to promptly pay when due all rents due and accruing to Prime Landlord under the
Prime Lease. Sublandlord will use reasonable efforts to enforce on behalf of
Subtenant Sublandlord's rights under the Prime Lease. Nothing contained in this
Sublease shall be construed as a guarantee by Sublandlord of any of the
obligations, covenants, warranties, agreements or undertakings of Prime Landlord
in the Prime Lease, nor as an undertaking by Sublandlord to Subtenant on the
same or similar terms as are contained in the Prime Lease.

         XIII.  INDEMNIFICATION. Subtenant and Sublandlord shall indemnify and
hold the other party harmless from and against any and all claims, demands
suits, judgments, liabilities, costs and expenses, including reasonable
attorney's fees, arising out of or in connection with such party's use and
possession of the Subleased Premises, or arising out of the failure of such
party, its agents, contractors or employees to perform any covenant, term or
condition of this Sublease or of the Prime Lease to be performed by the
respective parties hereunder.

         XIV.   ASSIGNMENT AND SUBLETTING. Subtenant shall be allowed to assign
this Sublease or sublet the Subleased Premises in whole or in part, only with
the prior written consent of Sublandlord and Prime Landlord pursuant to the
terms of Section 14 of the Prime Lease. Any excess consideration derived from
said assignment or sublet shall be divided pursuant to the terms of Section 14.3
of the Prime Lease.

         XV.    BROKERS. Each of Sublandlord and Subtenant represents and
warrants to the other that it has not dealt with any broker in connection with
this Sublease other than BT Commercial Real Estate (the "Broker"), and each
agrees to indemnify, defend and hold the other harmless from and against any
breach of said representation and warranty. Sublandlord shall be responsible for
any commission to be paid to the Broker pursuant to a separate agreement.

         XVI.   INSURANCE. Subtenant shall comply with all insurance
requirements of the Prime Lease, including the provisions of Section 11 thereof.
Subtenant shall deliver to Sublandlord certificates which evidence such
insurance prior to the Sublease Term Commencement Date, and thereafter as
required under the Prime Lease, and shall name in all such insurance policies
both the Prime Landlord and Sublandlord as additional insureds thereunder.

         XVII.  PARKING. Subtenant shall be entitled to the unassigned and
non-exclusive use of seventeen (17) parking spaces in the Parking Facility, in

                        counterpart originals, which, taken together, shall
                        constitute a single original instrument.

                B.      Notices. Notices to Sublandlord or Subtenant required or
                        permitted hereunder shall be sent in the manner
                        prescribed in the Prime Lease to the Subleased

                C.      Amendments. This Sublease may not be changed or
                        terminated orally but only by an agreement in writing
                        signed by both Sublandlord and Subtenant.

                D.      Estoppel Certificates. Sublandlord and Subtenant each

                        that this Sublease is in full force and effect and has
                        not been amended or modified (or describing such
                        amendment or modification, if any); (ii) the dates

                E.      No Waiver. The failure of either party to insist on
                        strict performance of any covenant or condition hereof,
                        or to exercise any option contained herein, shall not be
                        construed as a waiver of such covenant, condition or
                        option in any other instance.

                F.      Memorandum of Lease. Subtenant shall not record this
                        Sublease or any memorandum hereof.

                        California.

                        this Sublease will not impair or affect in any manner
                        the validity, enforceability or effect of the rest of
                        this Sublease.

                I.      Entire Agreement. All understandings and agreements,
                        oral or written, heretofore made between the parties
                        hereto are merged in this Sublease, which alone fully
                        and completely expresses the agreement between
                        Sublandlord and Subtenant.

                        it create any partnership, joint venture, or any
                        association or relationship between Sublandlord and
                        Subtenant other than as and to the extent specifically
