interest in all of the Collateral as security for the payment of all Secured
Obligations.

            2.2 The Debtors irrevocably appoint the Collateral Agent as their

      The Debtors represent and warrant that:

            3.1 Except as listed on the Schedules to the Credit Agreement, the
Debtors have granted no currently effective security interest in the Collateral
to any person other than to the Secured Parties, and no financing statement in
favor of any such other person as a secured party covering any of the Collateral
or any proceeds thereof is on file in any public office, and the Collateral is
free and clear of any Lien, charge or encumbrance, except pursuant to and under
this Security Agreement.

information with respect to the Collateral set forth in any schedule,
certificate or other writing furnished by Debtors to the Secured Parties, is
true and correct as of the date furnished. Debtors will have good title to all

through this Security Agreement a valid, perfected prior security interest
therein, except to the extent that the Collateral is acquired with purchase
money Indebtedness secured by purchase money Liens, as permitted under the
Credit Agreement, in which case the Secured Parties will


                                       3
<PAGE>

acquire a valid, perfected, subordinate security interest. Each statement of
Accounts to be delivered pursuant to the Credit Agreement will constitute a
representation by Debtors that the Accounts forming the basis therefor conform
to the definitions of Qualified Accounts. Debtors will continue to hold all
Collateral free and clear of all Liens excepting the rights of the Collateral
Agent hereunder and those Liens permitted pursuant to the terms of the Credit
Agreement.

under any name or trade name other than the names first recited above.

            3.6 Schedule C hereto is a true and complete list of all of the
Debtors' registered patents, trademarks and copyrights.

      4. Covenants and Agreements of Debtors.

      The Debtors covenant and agree that:

            4.1 The Secured Parties may examine and inspect the Collateral at
any reasonable time during regular business hours upon reasonable prior notice
and wherever located.

            4.2 Subject to the limitations of this Security Agreement, the
Debtors will from time to time upon demand furnish to the Collateral Agent such
further information and will execute, acknowledge and deliver to the Collateral
Agent such financing statements and assignments and other papers, pay any costs
of searches and filing fees, and will do all such other acts and things as the
Collateral Agent may reasonably request as being necessary or appropriate to
establish, perfect and maintain a valid security interest in the Collateral as
security for the Secured Obligations. Without limitation of the foregoing, the
Debtors will execute and deliver to the Secured Parties any document required to
acknowledge, register or perfect the security interest granted in any of the
Patent Rights, Technical Information, Trademark Rights or Copyrights and in any
of the Collateral under the Federal Assignment of Claims Act.

            4.3 The Debtors will defend the Collateral against all claims and
demands of all other persons at any time claiming the same or an interest
therein. Except to the extent permitted in the Credit Agreement, Debtors shall
not encumber any Collateral to any person other than the Secured Parties, or
sell, assign or transfer the Collateral or any right, title or interest therein
(other than the sale of Inventory in the ordinary course of the Debtors'
business and the sale or disposal of obsolete or unnecessary equipment).

            4.4 If any action or proceeding shall be commenced, other than any
action to collect the Secured Obligations, to which action or proceeding the
Secured Parties are made


                                       4
<PAGE>

parties and in which it becomes necessary to defend or uphold the Secured
Parties' security interests hereunder, all costs reasonably incurred by the
Secured Parties for the expenses of such litigation (including reasonable
counsel fees and expenses) shall be deemed part of the Secured Obligations
secured hereby, which the Debtors agree to pay or cause to be paid.

            4.5 All records of the Collateral will be located at the Debtors'
principal places of business. No Debtor shall change the location of any
Equipment or Inventory or the records pertaining to any Collateral to any
location not listed on Schedule B hereto unless such Debtor gives the Collateral
Agent not less than 14 days' prior written notice.

            4.6 The Debtors will have and maintain Insurance at their expense at
all times in such amounts, in such form, containing such terms and written by
such companies as may be reasonably satisfactory to the Collateral Agent (and as
more particularly set forth in the Credit Agreement). All policies of Insurance
shall be payable to the Collateral Agent and the Debtors, as their interests may
appear, and shall provide for thirty (30) days' written notice of cancellation
or modification to the Collateral Agent. The Collateral Agent is authorized by
the Debtors to act as their attorney in collecting, adjusting, settling or
canceling such Insurance and endorsing any drafts drawn by insurers. The Debtors
will immediately notify the Collateral Agent of any damage to or loss of the
Collateral in excess of $100,000. Not later than the expiration date of each
policy of Insurance then in effect, the Debtors shall deliver to the Collateral
Agent a certificate of Insurance certifying as to (i) the extension of such
policy or the issuance of a renewal policy therefor, describing the same in
reasonable detail satisfactory to the Collateral Agent and (ii) the payment in
full of the portion of the premium therefor then due and payable (or accompanied
by other proof of such payment satisfactory to the Secured Parties). The Debtors
shall be required forthwith to notify the Collateral Agent (by telephone,
confirmed in writing) if the Debtors shall determine at any time not to, or at
any time be unable to, extend or renew any such policy then in effect.

            4.7 The Debtors will use the Collateral for business purposes and
not in violation of any statute or ordinance.

            4.8 The Debtors will pay promptly when due all taxes and assessments
upon the Collateral or upon its use or sale ("Taxes"), except for any Taxes
which are being contested in good faith and for which adequate reserves under
generally accepted accounting principles have been established.

            4.9 The Debtors will at all times keep accurate and complete records
of the Accounts, Instruments and other Collateral and will deliver such
reconciliation reports and other financial information to the Collateral Agent
as the Collateral Agent may at any time reasonably request. The Collateral
Agent, or any of its agents, shall have the right to call at the Debtors' place
or places of business at reasonable intervals during regular business hours and
upon reasonable prior notice (except that no such prior notice shall be required
after the occurrence and during the continuance of a Default) to inspect, audit,
make test verifications and otherwise examine and make extracts from the books,
records, journals, orders, receipts, correspondence and other data relating to
any of the Collateral.

            4.10 Upon the occurrence and during the continuance of an Event of
Default, the Debtors agree to stamp all books and records pertaining to
Accounts, Instruments and General Intangibles to evidence the Secured Parties'
security interest therein in form satisfactory to the Collateral Agent
immediately upon the Collateral Agent's written demand.

            4.11 At its option, the Collateral Agent may discharge taxes, liens
or other encumbrances at any time levied against or placed on the Collateral
which have not been stayed as to execution and contested with due diligence in
appropriate legal proceedings, and the Collateral Agent may pay for Insurance on
the Collateral and may pay for maintenance and preservation of the Collateral.
The Debtors will, upon demand, remit to the Collateral Agent forthwith:

                  4.11.1   The amount of any such Taxes, assessments, Insurance
                           or other expenses which the Collateral Agent shall
                           have been required or elected to pay; and

                  4.11.2   The amount of any and all out-of-pocket expenses
                           which the Collateral Agent may reasonably incur in
                           connection with the exercise by the Collateral Agent
                           of any of the powers conferred upon it hereunder; and


                  4.11.3   interest on any amounts expended under Subsections
                           "4.11.1" and "4.11.2" of this Agreement from the date
                           of such expenditure to the date of repayment in full
                           to the Collateral Agent at a rate per annum which
                           shall automatically increase and decrease so that at
                           all times such rate shall remain two (2) percentage
                           points higher than the Prime Rate.

            4.12 Each Debtor will notify the Collateral Agent in writing at
least thirty (30) days prior to changing its chief executive office or other
locations at which it does business or changing its name or conducting business
under any name or trade name other than as warranted under Sections 3.3, 3.4,
and 3.5 hereof, in each case specifying the places or names involved.

            4.13 The Debtors will use commercially reasonable efforts to obtain
the consent of any person, governmental instrumentality or agency, or public
body or official to the assignment hereunder of any Account, Instrument,
Document or General Intangible if such consent may be required by the terms of
any contract or statute and if the such consent is reasonably necessary to
support the security interest hereunder and if the Collateral Agent so requests
in its discretion reasonably exercised.

            4.14 Upon the occurrence and during the continuance of an Event of
Default, the Collateral Agent shall have the right to notify the account debtors
obligated on any or all of the Debtors' Accounts, Chattel Paper, Instruments,
Documents, Securities or General Intangibles to make payment thereof directly to
the Collateral Agent, and the Collateral Agent may take control of all proceeds
of any thereof. The form of such notice to the account debtors shall be
substantially in the form of Exhibit 1 annexed hereto or such other form as the
Collateral Agent shall require.


                                       6
<PAGE>

      5. Events of Default.

            5.1 Upon the occurrence and during the continuance of an Event of
Default, the Secured Parties shall have all of the rights, powers and remedies
set forth in the Secured Loan Documents, together with the rights and remedies
of Secured Parties under the UCC, including without limitation, the right to
sell, lease or otherwise dispose of any or all of the Collateral, and to take
possession of the Collateral, and for that purpose the Collateral Agent may
enter peaceably any premises on which the Collateral or any part thereof may be
situated and remove the same therefrom and the Debtors will not resist or
interfere with such action. The Collateral Agent may require the Debtors to
assemble the Collateral and make the same available to the Collateral Agent at a
place to be designated by the Collateral Agent which is reasonably convenient to
both parties. The Debtors hereby agree that the place or places of location of
the Collateral are places reasonably convenient to the Debtors to assemble the
Collateral. Unless the Collateral is perishable or threatens to decline speedily
in value or is of a type customarily sold on a recognized market, the Collateral
Agent will send the Debtors reasonable notice of the time and place of any
public sale or reasonable notice of the time after which any private sale or any
other disposition thereof is to be made. The requirement of sending reasonable
notice shall be met if such notice is mailed, postage prepaid, to a Debtor at
least ten days before the time of the sale or disposition, or is personally
delivered at least seven days before the time of the sale or disposition.

            5.2 Upon demand by the Collateral Agent after the occurrence and
during the continuance of an Event of Default, the Debtors will immediately
deliver to the Collateral Agent all proceeds of Collateral, and all original
evidences of Accounts, Chattel Paper, Instruments, Documents, Securities or
General Intangibles, including, without limitation, all checks, drafts, cash and
other remittances, notes, trade acceptances or other instruments or contracts
for the payment of money, appropriately endorsed to the Collateral Agent's order
and, regardless of the form of such endorsement, the Debtors hereby waive
presentment, demand, notice of dishonor, protest and notice of protest and all
other notices with respect thereto; the Debtors hereby appoint the Collateral
Agent as the Debtors' agent and attorney-in-fact to make such endorsement on
behalf of and in the name of the Debtors. Pending such delivery, the Debtors
agree that they will not commingle any such checks, drafts, cash and other
remittances with any of the Debtors' funds or property, but will hold them
separate and apart therefrom and upon an express trust for the Collateral Agent
until delivery thereof is made to the Collateral Agent.

            5.3 The reasonable costs of collection and enforcement of Accounts,
Chattel Paper, Instruments, Documents, Securities or General Intangibles
including attorneys' fees and out-of-pocket expenses, shall be borne solely by
the Debtors, whether the same are incurred by the Collateral Agent or the
Debtors. The Debtors will not, after the occurrence and during the continuance
of an Event of Default, except with the Collateral Agent's express written
consent, extend, compromise, compound or settle any Account, Chattel Paper,
Instrument, Document, Security or General Intangible, or release, wholly or
partly, any person liable for payment thereof, or allow any credit or discount
thereon which is not customarily allowed by the Debtors in the ordinary conduct
of their business.

            5.4 Effective immediately upon the occurrence and during the
continuance of an Event of Default, the Debtors hereby appoint the Collateral
Agent to be the Debtors' true and


                                       7
<PAGE>

lawful attorney, with full power of substitution, in the Collateral Agent's name
or the Debtors' name or otherwise, for the Collateral Agent's sole use and
benefit, but at the Debtors' cost and expense, to exercise at any time all or
any of the following powers with respect to all or any of the Accounts, Chattel
Paper, Instruments, Documents, Securities or General Intangibles:

                           acquittance for any and all moneys due or to become

                           non-negotiable instruments taken or received by the
                           Collateral Agent in connection therewith (the Debtors
                           hereby waive notice of presentment, protest and
                           non-payment of any instrument so endorsed or
                           assigned);

                  5.4.3    to settle, compromise, compound, prosecute or defend
                           any action or proceeding with respect thereto;

                  5.4.4    to extend the time of payment of any or all thereof,
                           to make any allowance and other adjustments with
                           reference thereto;

                  5.4.5    to sell, transfer, assign or otherwise deal in or
                           with the same or the proceeds or avails thereof or
                           the relevant goods, as fully and effectually as if
                           the Collateral Agent were the absolute owner thereof;

                  5.4.6    to make any reasonable allowance and other reasonable
                           adjustments with reference thereto;

                  5.4.7    to sign the Debtors' name on any Document, on
                           invoices relating to any Account, on drafts against
                           customers, on schedules of assignments of Accounts,

                           Accounts, and on notices to customers;

                  5.4.8    to file or record in any public office notices of
                           assignment or any other public notice required to
                           effect this Security Agreement;

                  5.4.9    to notify the post office authorities to change the
                           address for delivery of the Debtors' mail to an
                           address designated by the Collateral Agent;

                  5.4.10   to receive, open and as appropriate to the purposes
                           of this Security Agreement and the Credit Agreement,
                           respond to or deal with, all mail addressed to the
                           Debtors;

                  5.4.11   to discharge Taxes, liens or other encumbrances at
                           any time levied against or placed thereon;


                                       8
<PAGE>

                  5.4.12   to send requests for verification of Accounts to the
                           Debtors' customers; and

                  5.4.13   to do all other things the Collateral Agent deems
                           reasonably necessary or desirable to carry out the
                           purposes of this Security Agreement.

The Debtors hereby ratify and approve all acts of the attorney pursuant to this
Section 5.4, and neither the Collateral Agent nor the attorney will be liable
for any act of commission or omission, nor for any error of judgment or mistake
of fact or law, other than acts, errors or mistakes due to willful malfeasance
or gross negligence by the Collateral Agent or the attorney; provided further,
however, that the Debtors do not waive any right under the UCC against the
Secured Parties for any action taken hereunder which is other than commercially
reasonable. This power, being coupled with an interest, is irrevocable so long
as any of the Secured Obligations remain outstanding.

            5.5 After deducting all reasonable expenses incurred by the
Collateral Agent in protecting or enforcing its rights in the Collateral, the
remainder of any proceeds of collection or sale of the Collateral shall be
applied to the payment of principal, interest or other charges comprising the
Secured Obligations in such order as the Collateral Agent may determine, and all
surplus shall be returned to the Debtors and the Debtors shall remain liable for
any deficiency. The Collateral Agent shall apply the proceeds of collection or
sale of the Collateral, if any, at least once during each calendar month, and
until so applied, shall retain such proceeds in the Collateral Account. The
Collateral Agent alone shall have the power of withdrawal from the Collateral
Account.

            5.6 The Secured Parties may exercise their rights with respect to
Collateral without resorting to or regard to other collateral or sources of
reimbursement for the Secured Obligations.

            5.7 The exercise by the Secured Parties of or failure to so exercise
any authority granted under this Security Agreement shall in no manner affect
any liability of any Debtor to any Secured Party, and provided, further, that
the Secured Parties 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.

      6. Waivers.

            6.1 The Debtors waive all demands, notices and protests of every
kind which are not expressly required under this Security Agreement or the
Secured Loan Documents and which are permitted by law to be waived, and which
would, if not waived, impair the Secured Parties' enforcement of this Security
Agreement or release any Collateral from the security interest of the Secured
Parties under this Security Agreement. By way of example, but not in limitation
of the Secured Parties' rights under this Security Agreement, the Secured
Parties do not have to give the Debtors notice of any of the following:

                  6.1.1    notice of acceptance of this Security Agreement;


                                       9
<PAGE>

                  6.1.2    notice of advances made, credit extended, Collateral
                           received or delivered;

                  6.1.3    any action which the Secured Parties do or do not
                           take regarding the Debtors, any other person, or any
                           other collateral securing the Secured Obligations;

                  6.1.4    enforcement of this Security Agreement against the
                           Collateral; or

                  6.1.5    any other action taken in reliance on this Security
                           Agreement.

            6.2 With respect both to Secured Obligations and Collateral, the
Debtors assent to any extension or postponement of the time of payment or any
other indulgence, to any substitution, exchange or release of Collateral, to the
addition or release of any party or person primarily or secondarily liable, to
the acceptance of partial payments thereon and the settlement, compromising or
adjusting of any thereof, all in such time or times as the Secured Parties may
deem advisable.

            6.3 The Secured Parties shall have no duty as to the collection or
protection of Collateral not in the Secured Parties' possession or control, and
the Secured Parties' duties with reference to Collateral in its possession or
control shall be to use reasonable care in the custody and preservation of such
Collateral, but such duty shall not require the Secured Parties to do any of the
following (although the Secured Parties are authorized to reasonably undertake
any such action if the Secured Parties deem such action appropriate):

                  6.3.1    protect any of the Collateral against the claims of
                           others;

                  6.3.2    collect any sums due on the Collateral;

                  6.3.3    exercise any rights under the Collateral;

                  6.3.4    notify the Debtors of any maturities or other similar
                           matters concerning the Collateral;

                  6.3.5    act upon any request the Debtors may make; or

                  6.3.6    preserve or protect the Debtors' rights in the
                           Collateral.

            6.4 Each Debtor waives all rules of suretyship law and any other law
whatsoever which is legally permitted to be waived and which would, if not
waived, impair the Secured Parties' enforcement of their security interests
hereunder. By way of example, but not in limitation of the Secured Parties'
rights under this Security Agreement, the Secured Parties may do any of the
following without notice to the Debtors, except to the extent that notice to any
Debtor is required under another Secured Loan Document or in each case in which
the agreement of any Debtor is required because such Debtor is a principal party
to a Secured Obligation and, as a matter of contract, the agreement of such
Debtor is required:


                                       10

                  6.4.1    change, renew or extend the time for repayment of all
                           or any part of the Secured Obligations;

                  6.4.2    change the rate of interest or any other provisions
                           with respect to all or any part of the Secured
                           Obligations;

                  6.4.3    release, surrender, sell or otherwise dispose of any
                           money or property which is in the Secured Parties'
                           possession as collateral security for the Secured
                           Obligations;

                  6.4.4    fail to perfect a security interest in any property
                           which is pledged or mortgaged as security for payment
                           of the Secured Obligations;

                  6.4.5    release or discharge any party liable to the Secured
                           Parties in whole or in part for the Secured
                           Obligations, or accept any additional parties or
                           guarantors;

                  6.4.6    delay or refrain from exercising any of the Secured
                           Parties' rights;

                  6.4.7    settle or compromise any and all claims pertaining to
                           the Secured Obligations and the Collateral; and

                  6.4.8    apply any money or property of a Debtor or that of
                           any other party liable to the Secured Parties for any
                           part of the Secured Obligations in any order it
                           chooses.

      10. No Waiver of Remedies.

      No failure to exercise and no delay in exercising, on the part of the
Secured Parties, any right, remedy, power or privilege under this Security
Agreement shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, remedy, power or privilege under this Security Agreement
preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege. The rights, remedies, powers and privileges
