                                    Recitals

        A.      Borrower and Bank entered into a certain Amended and Restated
Loan Agreement dated as of December 25, 1998 (as the same may from time to time
be modified, amended, supplemented, restated or superseded, the "Loan
Agreement"), pursuant to which Bank agreed to extend and make loans available to
Borrower upon the terms and conditions contained therein.

and "operating profitability" financial covenants set forth in Sections 10.A and
10.D., respectively, of the Loan Agreement for the fiscal quarter ending

(1) waive said financial covenant violations, (2) permit the acquisition by
Borrower of IDT Holdings, Inc. and Identicator Technology and (3) amend the
Minimum Tangible Net Worth covenant under the Loan Agreement, subject to all of
the terms and conditions set forth in this First Amendment.

        C.      The Loan Agreement, this First Amendment and the other Loan
Documents (as defined in the Loan Agreement), together with all other documents
entered into or delivered pursuant to any of the foregoing, in each case as
originally executed or as the same may from time to time be modified, amended,
supplemented, restated or superseded are hereinafter collectively referred to as
the "Loan Documents."

                                   Agreement

        Now, Therefore, in consideration of the foregoing recitals and the
mutual covenants herein set forth and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, and intending to
be legally bound, and to induce Bank to enter into this First Amendment,
Borrower and Bank hereby agree to amend the Loan Agreement as follows:

        1.      Definitions.  Unless otherwise defined herein, all terms defined
in the Loan Agreement have the same meaning when used herein.

        2.      Limited Waiver.  Bank hereby waives the Event of Default which
has occurred under Sections 10.A and 10.D of the Loan Agreement as a result of
the failure of Borrower to comply with the "Minimum Tangible Net Worth" and
"operating profitability" financial covenants for the fiscal quarter ending
December 31, 1998.

        3.      Consent.  Notwithstanding the occurrence of an Event of Default
as more fully described in Section 2 hereof, Bank hereby consents to and
Borrower may proceed with the acquisition of IDT Holdings, Inc. and Identicator
Technology.

        4.      Amendments to Loan Agreement.  The Loan Agreement is hereby
amended as follows:

                4.1     The definition of the Borrowing Base set forth under

     hereof, collectively, the "Borrowing Base") or..."

                4.2     Section 10.A. of the Loan Agreement is hereby deleted in
its entirety and the following section substituted therefor:

                "A.  At all times, maintain a Minimum Tangible Net Worth in an
     amount which is greater than the then outstanding principal amount of the
     Revolving Loan Account multiplied by 1.25. As used herein, "Tangible Net
     Worth" shall mean the sum of all assets, excluding any value for goodwill,
     Trademarks, Patents, Copyrights, organization expense, investments in its
     Subsidiaries, in-process technology, Accounts due from its Subsidiaries
     (excluding Accounts due from sale of any product of Borrower to ANADAC in

     intangible items, less all liabilities, plus Subordinated Debt;"

        5.      Limited Amendment and Waivers. Each of the amendments and
waivers set forth in this First Amendment shall be limited precisely as written
and shall not be deemed (a) to be an amendment or waiver of any other term or
condition of the Loan Agreement or the other Loan Documents, to prejudice any
right or remedy which Bank may now have or may have in the future under or in
connection with the Loan Agreement or the other loan Documents or (b) to be a
consent to any future amendment or waiver.

Borrower's best forecast of its sources and uses of cash from operations
(including but not limited to a schedule of collection of trade accounts
receivable), investing, and financing activities for the term of the Loan
Agreement, and shall be in form and substance satisfactory to Bank. Borrower's
failure to deliver said Statement of Cash Flows shall constitute an Event of
Default as defined in the Loan Agreement.

        7.       Representations And Warranties.  Borrower represents and
warrants that the representations and warranties respectively made in the Loan
Documents continue to be true and complete in all material respects as of the
date hereof after giving effect to this First Amendment (except to the extent

        9.      Release And Waiver.

                (a)     Borrower hereby acknowledges and agrees that: (1) it has
no claim or cause of action against Bank or any parent, subsidiary or affiliate
of Bank, or any of Bank's officers, directors, employees, attorneys or other
representatives or agents (all of which parties other than Bank being,
collectively, "Bank's Agents") in connection with the Loan Documents, the loans
thereunder or the transactions contemplated therein and herein; (2) it has no
offset or defense against any of its respective obligations, indebtedness or
contracts in favor of Bank; and (3) it recognizes that Bank has heretofore
properly performed and satisfied in a timely manner all of its obligations to
and contracts with Borrower.

                (b)     Although Bank regards its conduct as proper and does not
believe Borrower to have any claim, cause of action, offset or defense against
Bank or any of Bank's Agents in connection with the Loan Documents, the loans
thereunder or the transactions contemplated therein, Bank wishes and Borrower
agrees to eliminate any possibility that any past conditions, acts, omissions,
events, circumstances or matters could impair or otherwise affect any rights,
interests, contracts or remedies of Bank. Therefore, Borrower unconditionally
releases and waives (1) any and all liabilities, indebtedness and obligations,
whether known or unknown, of any kind of Bank or of any of Bank's Agents to
Borrower, except the obligations remaining to be performed by Bank as expressly
stated in the Loan Agreement, this First Amendment and the other Loan Documents
executed by Bank; (2) any legal, equitable or other obligations or duties,
whether known or unknown, of Bank or of any of Bank's Agents to Borrower (and
any rights of Borrower against Bank) besides those expressly stated in the Loan
Agreement, this First Amendment and the other Loan Documents; (3) any and all
claims under any oral or implied agreement, obligation or understanding with
Bank or any of Bank's Agents, whether known or unknown, which is different from
or in addition to the express terms of the Loan Agreement, this First Amendment
or any of the other Loan Documents; and (4) all other claims, causes of action
or defenses of any kind whatsoever (if any), whether known or unknown, which
Borrower might otherwise have against Bank or any of Bank's Agents, on account
of any condition, act, omission, event, contract, liability, obligation,
indebtedness, claim, cause of action, defense, circumstance or matter of any
kind whatsoever which existed, arose or occurred at any time prior to the
execution and delivery of this First Amendment or which could arise concurrently
with the effectiveness of this First Amendment.

                (c)     Borrower agrees that it understands the meaning and
effect of Section 1542 of the California Civil Code, which provides:

                        Section 1542. Certain Claims Not Affected by General
                        Release. A general release does not extend to claims
                        that the creditor does not know or suspect to exist in
                        his favor at the time of executing the release, which if
                        known by him must have materially affected his
                        settlement with the debtor.

BORROWER AGREES TO ASSUME THE RISK OF ANY AND ALL UNKNOWN, UNANTICIPATED OR
MISUNDERSTOOD DEFENSES, CLAIMS, CAUSES OF ACTION, CONTRACTS, LIABILITIES,

WHICH ANY SUCH LAWS MAY BE APPLICABLE, BORROWER WAIVES AND RELEASES (TO THE
MAXIMUM EXTENT PERMITTED BY LAW) ANY RIGHT OR DEFENSE WHICH IT MIGHT OTHERWISE
HAVE UNDER ANY OTHER LAW OF ANY APPLICABLE JURISDICTION WHICH MIGHT LIMIT OR
RESTRICT THE EFFECTIVENESS OR SCOPE OF ANY OF ITS WAIVERS OR RELEASES UNDER THIS
FIRST AMENDMENT.

        10.     Full Force And Effect; Entire Agreement.  Except to the extent
expressly provided in this First Amendment, the terms and conditions of the Loan
Agreement and the other Loan Documents shall remain in full force and effect.
