Collateral (the "Security Interest").

      3.    Representations, Warranties, Covenants and Agreements of the
Company. The Company represents and warrants to, and covenants and agrees with,
the Secured Party as follows:

            (a)   The Company has the requisite corporate power and authority to
enter into this Agreement and otherwise to carry out its obligations thereunder.
The execution, delivery and performance by the Company of this Agreement and the
filings contemplated therein have been duly authorized by all necessary action
on the part of the Company and no further action is required by the Company.
This Agreement constitutes a legal, valid and binding obligation of the Company
enforceable in accordance with its terms, except as enforceability may be
limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting the enforcement of creditor's rights generally.

            (b)   The Company represents and warrants that it has no place of
business or offices where its respective books of account and records are kept
(other than temporarily at the offices of its attorneys or accountants) or
places where Collateral is stored or located, except as set forth on Schedule A
attached hereto;

            (c)   The Company is the sole owner of the Collateral (except for
non-exclusive licenses granted by the Company in the ordinary course of
business), free and clear of any liens, security interests, encumbrances, rights
or claims, and is fully authorized to grant the Security Interest in and to
pledge the Collateral. There is not on file in any governmental or regulatory
authority, agency or recording office an effective financing statement, security
agreement, license or transfer or any notice of any of the foregoing (other than
those that have been filed in favor of the Secured Party pursuant to this
Agreement) covering or affecting any of the Collateral. So long as this
Agreement shall be in effect, the Company shall not execute and shall not
knowingly permit to be on file in any such office or agency any such financing
statement or other document or instrument (except to the extent filed or
recorded in favor of the Secured Party pursuant to the terms of this Agreement).

            (d)   No part of the Collateral has been judged invalid or
unenforceable. No written claim has been received that any Collateral or the
Company's use of any Collateral


                                       3
<PAGE>


violates the rights of any third party. There has been no adverse decision to
the Company's claim of ownership rights in or exclusive rights to use the
Collateral in any jurisdiction or to the Company's right to keep and maintain
such Collateral in full force and effect, and there is no proceeding involving
said rights pending or, to the best knowledge of the Company, threatened before
any court, judicial body, administrative or regulatory agency, arbitrator or
other governmental authority.

            (e)   The Company shall at all times maintain its books of account
and records relating to the Collateral at its principal place of business and
its Collateral at the locations set forth on Schedule A attached hereto and may
not relocate such books of account and records or tangible Collateral unless it
delivers to the Secured Party at least 30 days prior to such relocation (i)
written notice of such relocation and the new location thereof (which must be
within the United States) and (ii) evidence that appropriate financing
statements and other necessary documents have been filed and recorded and other
steps have been taken to perfect the Security Interest to create in favor of the
Secured Party valid, perfected and continuing first priority liens in the
Collateral.

            (f)   This Agreement creates in favor of the Secured Party a valid
security interest in the Collateral securing the payment and performance of the
Obligations and, upon making the filings described in the immediately following
sentence, a perfected first priority security interest in such Collateral.
Except for the filing of financing statements on Form-1 under the UCC with the
jurisdictions indicated on Schedule B, attached hereto, no authorization or
approval of or filing with or notice to any governmental authority or regulatory
body is required either (i) for the grant by the Company of, or the
effectiveness of, the Security Interest granted hereby or for the execution,
delivery and performance of this Agreement by the Company or (ii) for the
perfection of or exercise by the Secured Party of its rights and remedies
hereunder.

            (g)   On the date of execution of this Agreement, the Company will
deliver to the Secured Party one or more executed UCC financing statements on
Form-1 with respect to the Security Interest for filing with the jurisdictions
indicated on Schedule B, attached hereto and in such other jurisdictions as may
be requested by the Secured Party.

            (h)   The execution, delivery and performance of this Agreement does
not conflict with or cause a breach or default, or an event that with or without
the passage of time or notice, shall constitute a breach or default, under any
agreement to which the Company is a party or by which the Company is bound. No
consent (including, without limitation, from stock holders or creditors of the
Company) is required for the Company to enter into and perform its obligations
hereunder.

            (i)   The Company shall at all times maintain the liens and Security
Interest provided for hereunder as valid and perfected first priority liens and
security interests in the Collateral in favor of the Secured Party until this
Agreement and the Security Interest hereunder shall terminate pursuant to
Section 11. The Company hereby agrees to defend the same against any and all
persons. The Company shall safeguard and protect all Collateral for the account
of the Secured Party. At the request of the Secured Party, the Company will sign
and deliver to the Secured Party at any time or from time to time one or more
financing statements pursuant to the


                                       4
<PAGE>


UCC (or any other applicable statute) in form reasonably satisfactory to the
Secured Party and will pay the cost of filing the same in all public offices
wherever filing is, or is deemed by the Secured Party to be, necessary or
desirable to effect the rights and obligations provided for herein. Without
limiting the generality of the foregoing, the Company shall pay all fees, taxes
and other amounts necessary to maintain the Collateral and the Security Interest
hereunder, and the Company shall obtain and furnish to the Secured Party from
time to time, upon demand, such releases and/or subordinations of claims and
liens which may be required to maintain the priority of the Security Interest
hereunder.

            (j)   The Company will not transfer, pledge, hypothecate, encumber,
license (except for non-exclusive licenses granted by the Company in the
ordinary course of business), sell or otherwise dispose of any of the Collateral
without the prior written consent of the Secured Party.

            (k)   The Company shall keep and preserve its Equipment, Inventory
and other tangible Collateral in good condition, repair and order and shall not
operate or locate any such Collateral (or cause to be operated or located) in
any area excluded from insurance coverage.

            (l)   The Company shall, within ten (10) days of obtaining knowledge
thereof, advise the Secured Party promptly, in sufficient detail, of any
substantial change in the Collateral, and of the occurrence of any event which
would have a material adverse effect on the value of the Collateral or on the
Secured Party's security interest therein.

            (m)   The Company shall promptly execute and deliver to the Secured
Party such further deeds, mortgages, assignments, security agreements, financing
statements or other instruments, documents, certificates and assurances and take
such further action as the Secured Party may from time to time request and may
in its sole discretion deem necessary to perfect, protect or enforce its
security interest in the Collateral including, without limitation, the execution
and delivery of a separate security agreement with respect to the Company's
intellectual property ("Intellectual Property Security Agreement") in which the
Secured Party has been granted a security interest hereunder, substantially in a
form acceptable to the Secured Party, which Intellectual Property Security
Agreement, other than as stated therein, shall be subject to all of the terms
and conditions hereof.

            (n)   The Company shall permit the Secured Party and its
representatives and agents to inspect the Collateral at any time, and to make
copies of records pertaining to the Collateral as may be requested by the
Secured Party from time to time.

            (o)   The Company will take all steps reasonably necessary to
diligently pursue and seek to preserve, enforce and collect any rights, claims,
causes of action and accounts receivable in respect of the Collateral.

            (p)   The Company shall promptly notify the Secured Party in
sufficient detail upon becoming aware of any attachment, garnishment, execution
or other legal process levied against any Collateral and of any other
information received by the Company that may materially affect the value of the
Collateral, the Security Interest or the rights and remedies of the Secured
Party hereunder.


                                       5

            (r)   Schedule A attached hereto contains a list of all of the
subsidiaries of Company.

            (s)   The Company shall not, without the prior written consent of
the Secured Party, (i) create, incur, assume or suffer to exist any indebtedness

other than existing as of the date hereof; (ii) directly or indirectly declare,
pay or make any dividend or distribution on any class of its stock or apply any
of its funds, property or assets to the purchase, redemption or other retirement
of any of its stock, or issue any class of stock (iii) make or permit to exist
any loans or advances to any other person or entity, including any partnership

      4.    Defaults. The following events shall be "Events of Default":

            (a)   The occurrence of an Event of Default (as defined in the Note)
under the Note or under the Asset Purchase Agreement;

            (b)   Any representation or warranty of the Company in this
Agreement or in the Intellectual Property Security Agreement shall prove to have
been incorrect in any material respect when made;

            (c)   The failure by the Company to observe or perform any of its
obligations hereunder or in the Intellectual Property Security Agreement or
under the Asset Purchase Agreement for twenty (20) days after receipt by the
Company of notice of such failure from the Secured Party; or

            (d)   Any failure to perform their obligations or any breach of
their promises set forth in the NIR Letter by any of the Original Secured
Parties identified therein.

      5.    Duty To Hold In Trust. Upon the occurrence of any Event of Default
and at any time thereafter, the Company shall, upon receipt by it of any
revenue, income or other sums subject to the Security Interest, whether payable
pursuant to the Note or otherwise, or of any check, draft, note, trade
acceptance or other instrument evidencing an obligation to pay any such sum,
hold the same in trust for the Secured Party and shall forthwith endorse and
transfer any such sums or instruments, or both, to the Secured Party for
application to the satisfaction of the Obligations.

      6.    Rights and Remedies Upon Default. Upon occurrence of any Event of
Default and at any time thereafter, the Secured Party shall have the right to
exercise all of the remedies


                                       6
<PAGE>


conferred hereunder and under the Note, and the Secured Party shall have all the
rights and remedies of a secured party under the UCC and/or any other applicable
law (including the Uniform Commercial Code of any jurisdiction in which any
Collateral is then located). Without limitation, the Secured Party shall have
the following rights and powers:

            (a)   The Secured Party shall have the right to take possession of
the Collateral and, for that purpose, enter, with the aid and assistance of any
person, any premises where the Collateral, or any part thereof, is or may be
placed and remove the same, and the Company shall assemble the Collateral and
make it available to the Secured Party at places which the Secured Party shall
reasonably select, whether at the Company's premises or elsewhere, and make
available to the Secured Party, without rent, all of the Company's respective
premises and facilities for the purpose of the Secured Party taking possession
of, removing or putting the Collateral in saleable or disposable form.

            The Secured Party shall have the right to operate the business of
            the Company using the Collateral and shall have the right to assign,
            sell, lease or otherwise dispose of and deliver all or any part of
            the Collateral, at public or private sale or otherwise, either with
            or without special conditions or stipulations, for cash or on credit
            or for future delivery, in such parcel or parcels and at such time
            or times and at such place or places, and upon such terms and
            conditions as the Secured Party may deem commercially reasonable,
            all without (except as shall be required by applicable statute and
            cannot be waived) advertisement or demand upon or notice to the
            Company or right of redemption of the Company, which are hereby
            expressly waived. Upon each such sale, lease, assignment or other
            transfer of Collateral, the Secured Party may, unless prohibited by
            applicable law which cannot be waived, purchase all or any part of
            the Collateral being sold, free from and discharged of all trusts,
            claims, right of redemption and equities of the Company, which are
            hereby waived and released.

      7.    Applications of Proceeds. The proceeds of any such sale, lease or
other disposition of the Collateral hereunder shall be applied first, to the
expenses of retaking, holding, storing, processing and preparing for sale,
selling, and the like (including, without limitation, any taxes, fees and other
costs incurred in connection therewith) of the Collateral, to the reasonable
attorneys' fees and expenses incurred by the Secured Party in enforcing its
rights hereunder and in connection with collecting, storing and disposing of the
Collateral, and then to satisfaction of the Obligations, and to the payment of
any other amounts required by applicable law, after which the Secured Party
shall pay to the Company any surplus proceeds. If, upon the sale, license or
other disposition of the Collateral, the proceeds thereof are insufficient to
pay all amounts to which the Secured Party is legally entitled, the Company will
be liable for the deficiency, together with interest thereon, at the rate of 8%
per annum (the "Default Rate"), and the reasonable fees of any attorneys
employed by the Secured Party to collect such deficiency. To the extent
permitted by applicable law, the Company waives all claims, damages and demands
against the Secured Party arising out of the repossession, removal, retention or
sale of the Collateral, unless due to the gross negligence or willful misconduct
of the Secured Party.

      8.    Costs and Expenses. The Company agrees to pay all out-of-pocket
fees, costs and expenses incurred in connection with any filing required
hereunder, including without


                                        7
<PAGE>


limitation, any financing statements, continuation statements, partial releases
and/or termination statements related thereto or any expenses of any searches
reasonably required by the Secured Party. The Company shall also pay all other
claims and charges which in the reasonable opinion of the Secured Party would
prejudice, imperil or otherwise materially affect the Collateral or the Security
Interest therein. The Company will also, upon demand, pay to the Secured Party
the amount of any and all reasonable expenses, including the reasonable fees and
expenses of its counsel and of any experts and agents, which the Secured Party
may incur in connection with (i) the enforcement of this Agreement, (ii) the
custody or preservation of, or the sale of, collection from, or other
realization upon, any of the Collateral, or (iii) the exercise or enforcement of
any of the rights of the Secured Party under the Note. Until so paid, any fees
payable hereunder shall be added to the principal amount of the Note and shall
bear interest at the Default Rate.

      9.    Responsibility for Collateral. The Company assumes all liabilities
and responsibility in connection with all Collateral, and the obligations of the
Company hereunder or under the Note shall in no way be affected or diminished by
reason of the loss, destruction, damage or theft of any of the Collateral or its
unavailability for any reason.

      10.   Security Interest Absolute. All rights of the Secured Party and all
Obligations of the Company hereunder, shall be absolute and unconditional,
irrespective of: (a) any lack of validity or enforceability of this Agreement,
the Note or any agreement entered into in connection with the foregoing, or any
portion hereof or thereof; (b) any change in the time, manner or place of
payment or performance of, or in any other term of, all or any of the
Obligations, or any other amendment or waiver of or any consent to any departure
from the Note or any other agreement entered into in connection with the
foregoing; (c) any exchange, release or nonperfection of any of the Collateral,
or any release or amendment or waiver of or consent to departure from any other
collateral for, or any guaranty, or any other security, for all or any of the
Obligations; (d) any action by the Secured Party to obtain, adjust, settle and
cancel in its sole discretion any insurance claims or matters made or arising in
connection with the Collateral; or (e) any other circumstance which might
otherwise constitute any legal or equitable defense available to the Company, or
a discharge of all or any part of the Security Interest granted hereby. Until
the Obligations shall have been paid and performed in full, the rights of the
Secured Party shall continue even if the Obligations are barred for any reason,
including, without limitation, the running of the statute of limitations or
bankruptcy. The Company expressly waives presentment, protest, notice of
protest, demand, notice of nonpayment and demand for performance. In the event
that at any time any transfer of any Collateral or any payment received by the
Secured Party hereunder shall be deemed by final order of a court of competent
jurisdiction to have been a voidable preference or fraudulent conveyance under
the bankruptcy or insolvency laws of the United States, or shall be deemed to be
otherwise due to any party other than the Secured Party, then, in any such
event, the Company's obligations hereunder shall survive cancellation of this
Agreement, and shall not be discharged or satisfied by any prior payment thereof
and/or cancellation of this Agreement, but shall remain a valid and binding
obligation enforceable in accordance with the terms and provisions hereof. The
Company waives all right to require the Secured Party to proceed against any
other person or to apply any Collateral which the Secured Party may hold at any
time, or to marshal assets, or to pursue any


                                       8
<PAGE>


other remedy. The Company waives any defense arising by reason of the
application of the statute of limitations to any obligation secured hereby.

      11.   Term of Agreement. This Agreement and the Security Interest shall
terminate on the date on which all payments under the Note have been made in
full and all other Obligations have been paid or discharged. Upon such
termination, the Secured Party, at the request and at the expense of the
Company, will join in executing any termination statement with respect to any
financing statement executed and filed pursuant to this Agreement.

      12.   Power of Attorney; Further Assurances.

            (a)   The Company authorizes the Secured Party, and does hereby
make, constitute and appoint it, and its respective officers, agents, successors
or assigns with full power of substitution, as the Company's true and lawful
attorney-in-fact, with power, in its own name or in the name of the Company, to,
after the occurrence and during the continuance of an Event of Default, (i)
endorse any notes, checks, drafts, money orders, or other instruments of payment
(including payments payable under or in respect of any policy of insurance) in
respect of the Collateral that may come into possession of the Secured Party;
(ii) to sign and endorse any UCC financing statement or any invoice, freight or
express bill, bill of lading, storage or warehouse receipts, drafts against
debtors, assignments, verifications and notices in connection with accounts, and
other documents relating to the Collateral; (iii) to pay or discharge taxes,
liens, security interests or other encumbrances at any time levied or placed on
or threatened against the Collateral; (iv) to demand, collect, receipt for,
compromise, settle and sue for monies due in respect of the Collateral; and (v)
generally, to do, at the option of the Secured Party, and at the Company's
expense, at any time, or from time to time, all acts and things which the
Secured Party deems necessary to protect, preserve and realize upon the
Collateral and the Security Interest granted therein in order to effect the
intent of this Agreement and the Note, all as fully and effectually as the
Company might or could do; and the Company hereby ratifies all that said
attorney shall lawfully do or cause to be done by virtue hereof. This power of
attorney is coupled with an interest and shall be irrevocable for the term of
this Agreement and thereafter as long as any of the Obligations shall be
outstanding.

            (b)   On a continuing basis, the Company will make, execute,
acknowledge, deliver, file and record, as the case may be, in the proper filing
and recording places in any jurisdiction, including, without limitation, the
jurisdictions indicated on Schedule B, attached hereto, all such instruments,
and take all such action as may reasonably be deemed necessary or advisable, or
as reasonably requested by the Secured Party, to perfect the Security Interest
granted hereunder and otherwise to carry out the intent and purposes of this
Agreement, or for assuring and confirming to the Secured Party the grant or
perfection of a security interest in all the Collateral.

            (c)   The Company hereby irrevocably appoints the Secured Party as
the Company's attorney-in-fact, with full authority in the place and stead of
the Company and in the name of the Company, from time to time in the Secured
Party's discretion, to take any action and to execute any instrument which the

      15.   Miscellaneous.

            (a)   No course of dealing between the Company and the Secured
Party, nor any failure to exercise, nor any delay in exercising, on the part of
the Secured Party, any right, power or privilege hereunder or under the Note
shall operate as a waiver thereof; nor shall any single or partial exercise of
any right, power or privilege hereunder or thereunder preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.

            (b)   All of the rights and remedies of the Secured Party with
respect to the Collateral, whether established hereby or by the Note or by any
other agreements, instruments or documents or by law shall be cumulative and may
be exercised singly or concurrently.

            (c)   This Agreement constitutes the entire agreement of the parties
with respect to the subject matter hereof and is intended to supersede all prior
negotiations, understandings and agreements with respect thereto. Except as
specifically set forth in this Agreement, no provision of this Agreement may be
modified or amended except by a written agreement specifically referring to this
Agreement and signed by the parties hereto.

            (d)   In the event that any provision of this Agreement is held to
be invalid, prohibited or unenforceable in any jurisdiction for any reason,
unless such provision is narrowed by judicial construction, this Agreement
shall, as to such jurisdiction, be construed as if such invalid, prohibited or
unenforceable provision had been more narrowly drawn so as not to be invalid,
prohibited or unenforceable. If, notwithstanding the foregoing, any provision of
this Agreement is held to be invalid, prohibited or unenforceable in any
jurisdiction, such provision, as to such jurisdiction, shall be ineffective to
the extent of such invalidity, prohibition or unenforceability without
invalidating the remaining portion of such provision or the other provisions of
this Agreement and without affecting the validity or enforceability of such
provision or the other provisions of this Agreement in any other jurisdiction.

            (e)   No waiver of any breach or default or any right under this
Agreement shall be considered valid unless in writing and signed by the party
giving such waiver, and no such waiver shall be deemed a waiver of any
subsequent breach or default or right, whether of the same or similar nature or
otherwise.

            (f)   This Agreement shall be binding upon and inure to the benefit
of each party hereto and its successors and assigns.

            (g)   Each party shall take such further action and execute and
deliver such further documents as may be necessary or appropriate in order to
carry out the provisions and purposes of this Agreement.

            (h)   This Agreement shall be construed in accordance with the laws
of the State of New Jersey, except to the extent the validity, perfection or
enforcement of a security interest hereunder in respect of any particular
Collateral which are governed by a jurisdiction other than the State of New
Jersey in which case such law shall govern. Each of the parties hereto
irrevocably submits to the exclusive jurisdiction of New Jersey, Superior Court,
Somerset County over any action or proceeding arising out of or relating to this
Agreement, and the parties hereto hereby irrevocably agree that all claims in
respect of such action or proceeding may be


                                       11
<PAGE>


heard and determined in such New Jersey court. The parties hereto agree that a
final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. The parties hereto further waive any objection to venue in the
State of New Jersey and any objection to an action or proceeding in the State of
New Jersey on the basis of forum non conveniens.

            (i)   EACH PARTY HERETO HEREBY AGREES TO WAIVE ITS RESPECTIVE RIGHTS
TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF
THIS AGREEMENT. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF
ANY DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATER
OF THIS AGREEMENT, INCLUDING WITHOUT LIMITATION CONTRACT CLAIMS, TORT CLAIMS,
BREACH OF DUTY CLAIMS AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. EACH PARTY
HERETO ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL INDUCEMENT FOR EACH PARTY TO
ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH PARTY HAS ALREADY RELIED ON THIS
WAIVER IN ENTERING INTO THIS AGREEMENT AND THAT EACH PARTY WILL CONTINUE TO RELY
ON THIS WAIVER IN THEIR RELATED FUTURE DEALINGS. EACH PARTY FURTHER WARRANTS AND
REPRESENTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT
SUCH PARTY HAS KNOWINGLY AND VOLUNTARILY WAIVES ITS RIGHTS TO A JURY TRIAL
FOLLOWING SUCH CONSULTATION. THIS WAIVER IS IRREVOCABLE, MEANING THAT,
NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, IT MAY NOT BE MODIFIED EITHER
ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS,
RENEWALS AND SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT. IN THE EVENT OF A
LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE
COURT.

            (j)   This Agreement may be executed in any number of counterparts,
each of which when so executed shall be deemed to be an original and, all of
which taken together shall constitute one and the same Agreement. In the event
that any signature is delivered by facsimile transmission, such signature shall
create a valid binding obligation of the party executing (or on whose behalf
such signature is executed) the same with the same force and effect as if such
facsimile signature were the original thereof.
