<PAGE>

         SECTION 3.REPRESENTATIONS AND WARRANTIES OF DEBTOR. The Debtor hereby

hereof, no financing statement covering the Collateral is on file in any public

any event causing a substantial loss or diminution in the value of all or any

which could materially and adversely affect the Debtor's business.

         SECTION 5.RECORDS RELATING TO COLLATERAL. The Debtor will keep its
records concerning the Collateral at its offices designated in the caption of
this Security Interest Agreement or at such other place or places of business of
which the Secured Party shall have been notified in writing no less than ten
(10) days prior thereto. The Debtor will hold and preserve such records and
chattel paper and will permit representatives of the Secured Party at any time

<PAGE>

         SECTION 6.GENERAL AUTHORITY. From and during the term of any Debtor
Event of Default, the Debtor hereby appoints the Secured Party the Debtor's
lawful attorney, with full power of substitution, in the name of the Debtor, for
the sole use and benefit of the Secured Party, but at the Debtor's expense, to
exercise, all or any of the following powers with respect to all or any of the
Collateral:

         (a)to demand, sue for, collect, receive and give acquittance for any
and all monies due or to become due;

         (b)to receive, take, endorse, assign and deliver all checks, notes,
drafts, documents and other negotiable and non- negotiable instruments and
chattel paper taken or received by the Secured Party;

         (c)to settle, compromise, prosecute or defend any action or proceeding
with respect thereto;

         (d)to sell, transfer, assign or otherwise deal in or with the same or
the proceeds thereof or the related goods securing the Collateral, as fully and
effectually as if the Secured Party were the sole and absolute owner thereof;

         (e)to extend the time of payment of any or all thereof and to make any
allowance and other adjustments with reference thereto; and

         (f)to discharge any taxes, liens, security interests or other
encumbrances at any time placed thereon;

provided, however, that the Secured Party shall give the Debtor not less than
ten (10) business days prior written notice of the time and place of any sale or
other intended disposition of any of the Collateral.

         The exercise by the Secured Party or by the Agent of or failure to so
exercise any authority granted herein shall in no manner affect Debtor's
liability to the Secured Party, and provided, further, that the Secured Party
and the Agent shall be under no obligation or duty to exercise any of the powers
hereby conferred upon them and they shall be without liability for any act or
failure to act in connection with the collection of, or the preservation of, any
rights under any of the Collateral.

         SECTION 7. DEBTOR EVENTS OF DEFAULT.

                                    (a)The Debtor shall be in default under this
Security Agreement upon the occurrence of an Event of Default (as defined in the
Note) by the Debtor (a "Debtor Event of Default").

                                    (b)The Debtor hereby irrevocably agrees
that, upon the occurrence of a Debtor Event of Default, the Debtor shall be
deemed to have consented to an immediate conveyance and transfer to the Secured
Party of the copyrights and all other rights the Debtor may have in the software
included in the Collateral, including, but not necessarily limited to, the
software identified in Schedule B attached hereto. In furtherance of the
foregoing, and not in limitation thereof, the Debtor will, upon the occurrence
of a Debtor Event of Default, deliver to the Secured Party copies of the source
code of the relevant software, with accompanying written assignment of the
software to the Secured Party. Without limiting the foregoing, such source code
and assignment shall be in form sufficient to enable the Secured Party to
register the software in Secured Party's name with the Copyright Register. The
Debtor hereby agrees to take all steps necessary or appropriate, as requested by
the Secured Party, to effectuate and reflect such conveyance and transfer or
assignment to Secured Party. In all events, such conveyance, transfer or
assignment shall be deemed to vest title in such software in the Secured Party.

                                    (c) In furtherance of the foregoing and not
in limitation thereof, the Debtor acknowledges and agrees that the Secured Party
may, upon the occurrence of a Debtor Event of Default, seek the immediate entry
of a preliminary injunction prohibiting the Debtor's use of such software in any
shape, way or manner, including, but not necessarily limited to, through the
sale of products that use any of such software, and the Debtor hereby
irrevocably agrees that it will not contest an application seeking entry of a
preliminary injunction and that it will accept the entry of such injunction.

         SECTION 8.REMEDIES UPON DEBTOR EVENT OF DEFAULT. If any Debtor Event of
Default shall have occurred, then in addition to the provisions of Section 7
hereof, the Secured Party may exercise all the rights and remedies of a secured
party under the Code. The Secured Party may require the Debtor to assemble all
or any part of the Collateral and make it available to the Secured Party at a
place to be designated by the Secured Party which is reasonably convenient. The
Secured Party shall give the Debtor ten (10) business days prior written notice
of the Secured Party's intention to make any public or private sale or sale at a
broker's board or on a securities exchange of the Collateral. At any such sale
the Collateral may be sold in one lot as an entirety or in separate parcels, as
the Secured Party, in its sole discretion, may determine. The Secured Party
shall not be obligated to make any such sale pursuant to any such notice. The
Secured Party may, without notice or publication, adjourn any public or private
sale or cause the same to be adjourned from time to time by announcement at the
time and place fixed for the sale, and such sale may be made at any time or
place to which the same may be adjourned. The Secured Party, instead of
exercising the power of sale herein conferred upon it, may proceed by a suit or
suits at law or in equity to foreclose the Security Interests and sell the
Collateral, or any portion thereof, under a judgment or decree of a court or
courts of competent jurisdiction.

applied in the following order of priorities: (a) first, to pay the reasonable
expenses of such sale or other realization, including, without limitation,
reasonable attorneys' fees, and all expenses, liabilities and advances
reasonably incurred or made by the Secured Party in connection therewith, and
any other unreimbursed expenses for which the Secured Party is to be reimbursed
pursuant to the Section titled "Expenses; Secured Party's Lien" below; (b)
second, to the payment of the Obligations in such order of priority as the
Secured Party, in its sole discretion, shall determine; and (c) finally, to pay
to the Debtor, or its successors or assigns, or as a court of competent
jurisdiction may direct, any surplus then remaining from such proceeds.

         SECTION 10.EXPENSES; SECURED PARTY'S LIEN. If any Debtor Event of
Default shall have occurred, the Debtor will forthwith upon demand pay to the
Secured Party: (a) the amount which the Secured Party may have been required to
pay to free any of the Collateral from any lien thereon; and (b) the amount of
any and all reasonable out-of-pocket expenses, including, without limitation,
the reasonable fees and disbursements of its counsel, and of any agents not
regularly in its employ, which the Secured Party may incur in connection with
the collection, sale or other disposition of any of the Collateral.

         SECTION 11.TERMINATION OF SECURITY INTERESTS; RELEASE OF COLLATERAL.
Upon the payment, performance or other satisfaction in full of all the
Obligations, the Security Interests shall terminate and all rights to the
Collateral shall revert to the Debtor. Upon any such termination of the Security
Interests or release of Collateral, the Secured Party will, at the Debtor's
expense, to the extent permitted by law, execute and deliver to the Debtor such
documents as the Debtor shall reasonably request to evidence the termination of
the Security Interests or the release of such Collateral, as the case may be.

         SECTION 12.NOTICES. All notices, demands, requests, consents,
approvals, and other communications required or permitted hereunder shall be in

confirmation generated by the transmitting facsimile machine, at the address or
number designated below (if delivered on a business day during normal business
hours where such notice is to be received), or the first business day following
such delivery (if delivered other than on a business day during normal business
hours where such notice is to be received) or (ii) on the second business day
following the date of mailing by express courier service or on the fifth
business day after deposited in the mail, in each case, fully prepaid, addressed
to such address, or upon actual receipt of such mailing, whichever shall first
occur. The addresses for such communications shall be for (i) the Debtor as
provided in the Bridge Loan Agreement for notices to the Company, (ii) for each
Secured Party as provided in the Bridge Loan Agreement for notices to the Lender
and (iii) for the Agent as provided in the Bridge Loan Agreement for notices to

         SECTION 13. AGENT.

         (a)Anything in the other provisions of this Security Interest Agreement
to the contrary notwithstanding, the Secured Party may designate another entity
to act as agent (the "Agent") for the Secured Party with respect to any one or
more of the rights of Secured Party hereunder, including, but not necessarily
limited to, the right to hold the security interest and/or be named as secured
party (as agent for the Secured Party) in any filed financing statement and to
take action in the name and stead of the Secured Party hereunder. Such
designation may be made with or without power of substitution, Such designation
shall remain in effect until canceled by the Secured Party, as provided herein;
provided, however, that such cancellation shall not affect the validity of any
action theretofore taken by such agent pursuant to this Security Interest
Agreement. The Debtor acknowledges and agrees to honor such designation and
acknowledges that the Agent is acting as the agent of the Secured Party and not
as a principal.

         (b)Each Secured Party hereby confirms that the Secured Party has
designated Krieger & Prager, LLP (acting by Samuel M. Krieger and Ronald
Nussbaum, or either one of them), as its initial Agent, with full right of
substitution.

         (c)If there is more than one Secured Party, the Agent shall act as
agent for all Secured Parties. Any revocation of the authority of the Agent or
the designation of an alternate Agent shall be done only by Secured Parties who
represent a Majority in Interest of the Holders (as defined below) at that time;
provided that at all times all Secured Parties shall be represented by one and
the same Agent. The term "Majority in Interest of the Holders" means, as of the
relevant date, one or more Secured Parties whose respective outstanding
principal amounts of the Notes held by each of them, as of such date, aggregate
more than fifty percent (50%) of the aggregate outstanding principal amounts of
the outstanding Notes held by all Secured Parties on that date.

         (d)Reference is made to the provisions of Sections 2 through 15,
inclusive, of the Joint Escrow Instructions. All such provisions are
incorporated herein by reference, as if set forth herein in full, except that,
for such purposes, the references therein to (i) the "Escrow Agent" shall be
deemed to be references to the "Agent" under this Security Interest Agreement,
(ii) the "Company" shall be deemed to be references to the Debtor under this
Security Interest Agreement, and (iii) the "Lender" shall be deemed to be
references to the relevant Secured Party under this Security Interest Agreement.

         SECTION 14. MISCELLANEOUS.

         (a)No failure on the part of the Secured Party to exercise, and no
delay in exercising, and no course of dealing with respect to, any right, power
or remedy under this Security Interest Agreement shall operate as a waiver
thereof; nor shall any single or partial exercise by the Secured Party of any
right, power or remedy under this Security Interest Agreement preclude the
exercise, in whole or in part, of any other right, power or remedy. The remedies
in this Security Interest Agreement are cumulative and are not exclusive of any
other remedies provided by law. Neither this Security Interest Agreement nor any
provision hereof may be changed, waived, discharged or terminated orally but
only by a statement in writing signed by the party against which enforcement of
the change, waiver, discharge or termination is sought.

Agreement and all documents delivered in connection herewith have been duly and
validly authorized by all necessary corporate action of Debtor and this
Agreement and all documents delivered in connection herewith have been duly and
validly executed and delivered by Debtor. The execution and delivery by Debtor
of this Security Interest Agreement and all documents delivered in connection
herewith will not result in a breach or default of or under the Certificate of
Incorporation, By-laws or any agreement, contract or indenture of Debtor. This
Security Interest Agreement and all documents delivered in connection therewith
are legal, valid and binding obligations of Debtor enforceable against Debtor in
accordance with their terms.

         (c)In the event that any action is taken by Debtor or Secured Party in
connection with the this Security Interest Agreement, or any related document or
matter, the losing party in such legal action, in addition to such other damages
as he or it may be required to pay, shall pay reasonable attorneys' fees to the
prevailing party.

         SECTION 15.SEPARABILITY. If any provision hereof shall prove invalid or
unenforceable in any jurisdiction whose laws shall be deemed applicable, the
other provisions hereof shall remain in full force and effect in such
jurisdiction and shall be liberally construed in favor of the Secured Party.

                                       8

         SECTION 16. GOVERNING LAW.

         (a)This Security Interest Agreement shall be governed by and construed
in accordance with the laws of the State of Delaware for contracts to be wholly
performed in such state and without giving effect to the principles thereof
regarding the conflict of laws. Each of the parties consents to the exclusive
jurisdiction of the federal courts whose districts encompass any part of the
City of Wilmington or (except with respect to issues relating to the copyright
in and to the software, as contemplated by Section 7 hereof, which shall
exclusively be in the aforesaid federal courts) or of the state courts of the
State of Delaware sitting in the City of Wilmington in connection with any
dispute arising under this Security Interest Agreement and hereby waives, to the
maximum extent permitted by law, any objection, including any objection based on
FORUM NON COVENIENS, to the bringing of any such proceeding in such
jurisdictions or to any claim that such venue of the suit, action or proceeding
is improper. To the extent determined by such court, the Debtor shall reimburse
the Secured Party for any reasonable legal fees and disbursements incurred by
the Secured Party in enforcement of or protection of any of its rights under
this Security Interest Agreement. Nothing in this Section shall affect or limit
any right to serve process in any other manner permitted by law.

         (b) The Debtor and the Secured Party acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Security Interest Agreement were not performed in accordance with their specific
terms or were otherwise breached. It is accordingly agreed that the parties
shall be entitled to an injunction or injunctions to prevent or cure breaches of
the provisions of this Security Interest Agreement and to enforce specifically
the terms and provisions hereof, this being in addition to any other remedy to
which any of them may be entitled by law or equity.

         SECTION 16.JURY TRIAL WAIVER. The Debtor and the Secured Party hereby
waive a trial by jury in any action, proceeding or counterclaim brought by
either of the parties hereto against the other in respect of any matter arising
out of or in connection with the Note or this Security Interest Agreement.

         SECTION 17.ASSIGNMENT. Except in connection with the transfer of all of
