during any month thereafter shall not exceed $2,000,000 during any such month.

1.2.  Joint and Several Obligations.  The obligations of the Borrowers hereunder
      -----------------------------
are and shall be joint and several. Each Borrower hereby irrevocably appoints
the Company as its respective agent for purposes of making all requests for
Advances, and executing such documents and taking all other actions required or
permitted hereunder, and agrees that all communications by or to the Company and
all execution of documents and other actions taken

                                       1
<PAGE>

by the Company in connection with this Agreement shall be binding on each
Borrower as fully as if such Borrower had made such requests, executed such
documents and/or taken such actions itself.

1.3   Promissory Note. The indebtedness of the Borrowers to the Lender will be
      ---------------
evidenced by a Note executed by the Borrowers, jointly and severally, in favor
of the Lender. The outstanding principal balance of the Loan together with all
interest accrued thereon shall be due and payable in full on the earliest to
occur of (i) January 31, 2001, or (ii) the third business day after the closing
date of the Initial Public Offering (as hereinafter defined), or (iii) the third
business day after the closing date of the Refinancing (as hereinafter defined).
Notwithstanding the foregoing, the aggregate outstanding principal balance of
the loan and all interest accrued thereon shall be due and payable immediately
on acceleration of the loan in accordance with Section 7 hereof.

1.4.  Effectiveness. The effectiveness of this Agreement shall be subject to the
      -------------
Lender's receipt of the following documents, each in form and substance
reasonably satisfactory to the Lender: (i) certified copies of appropriate
authorizing resolutions of the Board of Directors of each Borrower authorizing
such Borrower's execution and performance of this Agreement, the Note and the
Loan Documents, (ii) Uniform Commercial Code financing statement searches
against the Borrowers in such jurisdictions as the Lender shall reasonably
require, (iii) the Security Documents (as hereinafter defined) duly executed by
the Borrowers, and (iv) the Note duly executed by the Borrowers.

1.5   Advances. The Company on behalf of the Borrowers shall give the Lender
      --------
prior written (which may be telecopied) notice of each requested Advance under
this Agreement by delivery of an Advance Request Form in the form of Exhibit A
hereto, certified by the President, any Vice President or the Chief Financial
Officer of the Company. The Advance Request Form shall specify the date, amount
and purpose of the Advance and shall contain the following information and
representations, which shall be required to be true and correct as of the date
delivered and as of the date of the requested Advance:

      (i)   the aggregate amount of the requested Advance;

      (ii)  the purpose of the requested Advance;

      (iii) confirmation of the Borrower's compliance on the date of the request
            for the Advance with the covenants in Sections 4 and 5 hereof;

      (iv)  certification that the representations and warranties set forth in
            Section 3 hereof are true and correct in all material respects as of
            the date of the Advance and no

                                       2
<PAGE>

            Event of Default or Default hereunder has occurred and is then
            continuing or would occur as a result thereof; and

      (v)   certification that there have been no Material Adverse Effect since
            the date of this Agreement.

      Each of the representations and warranties set forth in subparagraphs
(iii), (iv), and (v) above shall be deemed to have been made by the Borrowers on
the date of each request for an Advance.  Each of the Borrowers hereby
irrevocably authorizes and requests that the Company execute all Advance Request
Forms on its respective behalf, in each case with the same force and effect as
if such entity had executed such Advance Request Form itself.

1.6   Conditions.  It shall be a condition to the Lender's obligation hereunder
      ----------
to make any Advance that the Lender receive a completed Advance Request Form and
that the representations set forth herein shall be true and correct as if made
on the date of such Advance (except for such representations and warranties as
expressly relate to a prior date), no Event of Default or Default shall have
occurred and be continuing on the date of such Advance, and there shall have
been no Material Adverse Effect since the date of this Agreement.

1.7   Optional Prepayments. The Borrowers may, at their option, at any time and
      --------------------
from time to time, prepay all or any part of the outstanding principal balance
of the Loan, without penalty or premium, in multiples of $50,000, provided that
concurrently with each such prepayment the Borrowers shall pay accrued interest
on the principal so prepaid to the date of such prepayment. The amounts of such
prepayments may be reborrowed, subject to the limitations in Section 1.1.

1.8.  Day of Payment. Whenever any payment to be made hereunder shall become due
      --------------
and payable on a day which is not a Business Day (as defined below), such
payment may be made on the next succeeding Business Day and, in the case of any
payment of principal, such extension of time shall in such case be included in
computing interest on such payment. As used herein, "Business Day" shall mean
any day which is not a Saturday or Sunday and on which banks in the State of New
York are not authorized or required to close. Interest on past due principal and
accrued interest thereon shall be calculated as follows: The amount of principal
past due multiplied by the Default Rate and multiplied by a fraction, the
numerator of which is the number of days such principal and interest is past due
and the denominator of which is 360.

1.9.  Use of Proceeds. Funds advanced under the Loan shall be used solely for
      ---------------
(i) development of the Company's Free Trade Zone, and (ii) the working capital
purposes and capital expenditures of the Borrowers.

<PAGE>

1.10. Obligation to Pay.  The Borrowers shall make all payments hereunder in
      -----------------
full without offset, reduction or deduction of any kind or amount or for any
reason. Notwithstanding the face amount of the Note, the liability of the
Borrowers shall be equal at all times to the actual outstanding principal
indebtedness to the Lender under the Note together with interest thereon and all
fees, costs and expenses provided herein.

SECTION 2.  COLLATERAL

2.1   Security Documents. The Loan shall be secured by and the Lender shall be
      ------------------
entitled to the benefits of Security Agreements executed by each of the
Borrowers on the date hereof (collectively, the "Security Documents"). The
Borrowers shall duly execute and deliver the Security Documents, all consents of
third parties necessary to permit the effective granting of the Liens created in
such agreements, financing statements pursuant to the Uniform Commercial Code
and other documents, all in form and substance satisfactory to the Lender, as
may be reasonably required by the Lender to grant to the Lender a valid,
perfected and enforceable first priority Lien (except for the Lien of Marine
Midland Bank referred to in Section 3.14) on and security interest in the
Collateral. The Borrowers shall file or cause to be filed such financing
statements in each jurisdiction necessary to grant the Lender a valid, perfected
and enforceable first priority Lien (except for the Lien of Marine Midland Bank
referred to in Section 3.14) on and security interest in the Collateral not
later than five business days after the date of this Agreement. As promptly as
practicable, but in no event later than January 10, 2000, the Borrowers shall

Marine Midland Bank.

3.    REPRESENTATIONS AND WARRANTIES OF BORROWERS. The Borrowers hereby jointly
      -------------------------------------------
and severally represent and warrant to the Lender as follows (provided that such
representations and warranties with respect to IQXpert Holdings Inc., IQXpert
Inc. and ExtraTime Technologies Inc. shall be subject to Section 3.19):

3.1   Due Organization and Qualification.  Each Borrower is duly organized,
      ----------------------------------
validly existing and in good standing under the laws of the jurisdiction of its
formation. Each Borrower has all requisite corporate power and authority to own,
lease and operate its assets and properties and to

                                       4
<PAGE>

carry on its business as presently conducted and as presently contemplated. Each
Borrower is duly qualified to transact business and is in good standing in each
jurisdiction in which the nature of its business or the location of its property
requires such qualification, except where the failure to do so would not have a
material adverse effect on its business, operations, assets, prospects or
condition (financial or otherwise). The Company does not have any domestic
Subsidiary except as listed on Schedule 1 hereto.

3.2   Constituent Documents.  True and complete copies of each Borrower's
      ---------------------
Certificate of Incorporation and By-laws, as in effect on the date hereof
(collectively, the "Borrower Constituent Documents"), have been delivered to the
Lender.

3.3.  Financial Statements.  The audited consolidated balance sheet and related
      --------------------
statements of income and cash flow for the Company as at and for the fiscal year
ended on December 31, 1998 (the "1998 Financial Statements") and the unaudited
consolidated balance sheet (the "Company Interim Balance Sheet") and related
statement of income of the Company as at and for the nine-month period ended on
September 30, 1999 (collectively, the "Company Interim Financial Statements";
and together with the 1998 Financial Statements, the "Company Financial
Statements"), true and complete copies of all of which have been delivered to
the Lender, present fairly in all material respects the consolidated financial
condition of the Company as at the dates indicated therein and the consolidated
results of operations of the Company for the periods covered thereby. The
Company Financial Statements have been prepared in accordance with GAAP
consistently applied, subject only in the case of the Company Interim Financial
Statements to ordinary year-end adjustments, none of which are material
individually or in the aggregate, and the absence of footnotes. The financial
books and records of the Company are in all material respects complete and
correct, have been maintained in accordance with good business practices, and
accurately reflect the bases for the consolidated financial condition and
results of operations set forth in the Company Financial Statements.

3.4   Absence of Changes. Since December 6, 1999, there has not been (i) any
      ------------------
significant adverse change in the financial condition, results of operations,
assets or business of the Borrowers, (ii) any repayment of any indebtedness or
any borrowing of or agreement to borrow any money or any material Liabilities
incurred by the Borrowers, other than current Liabilities incurred in the
ordinary course of business, (iii) any material asset or property of the
Borrowers made subject to a Lien, (iv) any declaration or payment of dividends
on, or other distributions with respect to, or any direct or indirect redemption
or repurchase of, any shares of the capital

                                       5
<PAGE>

stock of Borrowers, (v) any issuance of any stocks, bonds or other securities of
the Borrowers, or any options, warrants or rights or agreements or commitments
to purchase or issue such securities, (vi) any mortgage, pledge, sale,
assignment or transfer of any material tangible or intangible assets of the
Borrowers, except with respect to tangible assets effected in the ordinary
course of business to persons not related to the Borrowers, (vii) any loan by
the Borrowers to any officer, director, employee or shareholder of the Borrowers
or any affiliate thereof, (viii) any material damage, destruction or loss
(whether or not covered by insurance) adversely affecting the assets, property
or business of the Borrowers, (ix) any purchase or other acquisition of assets
or property by the Borrowers other than in the ordinary course of business, (x)
any change in the accounting methods or practices followed by the Borrowers,
(xi) any operation of the business of the Borrowers outside of the ordinary
course of business and/or inconsistent with past practice, (xii) any waiver of
any valuable right of the Borrowers, or the cancellation or reduction of any
material debt or claim held by the Borrowers, or (xiii) any commitment or
agreement (contingent or otherwise) to do any of the foregoing.

3.5   Power and Authority.  Each of the Borrowers has the requisite corporate
      -------------------
power and authority to execute and deliver this Agreement and all other
agreements and certificates referred to in or contemplated by this Agreement and
to perform its obligations hereunder and thereunder. The execution, delivery and
performance of this Agreement and all other agreements and certificates referred
to in or contemplated by this Agreement have been duly authorized by all
necessary corporate action on the part of the Borrowers. This Agreement has been
duly executed and delivered by the Borrowers and is (and such other agreements
and certificates, when executed and delivered, will be) the valid and binding
obligations of the Borrowers enforceable against the Borrowers in accordance
with its terms, except as such enforceability may be limited by applicable
bankruptcy, moratorium, insolvency, reorganization or other similar laws now or
hereafter in effect relating to or affecting creditors' rights generally and
general equitable principles (whether considered in a proceeding in equity or at
law).

3.6   Tax Matters.  Each of the Borrowers has timely filed all Tax Returns that
      -----------
it has been required to file through the date hereof, and has timely paid in
full all Taxes which were due and payable by it through the date hereof. The
provisions for Taxes reflected on the Company Interim Balance Sheet are adequate
to cover all accrued and unpaid Taxes of the Company for all periods ending on
or before September 30, 1999, and nothing has occurred subsequent to that date
to make such provisions inadequate. The Company has established and is
maintaining current accruals, and will establish and maintain adequate accruals
subsequent to the date hereof, that are in the case of current accruals, and
will be in the case of accruals subsequent to the date

                                       6
<PAGE>

hereof, accurately reflected in the books and records of the Company and are,
and will be, adequate for the payment of any Taxes incurred but not yet due and
payable. No waivers or extensions of any applicable statute of limitations for
the assessment or collection of Taxes with respect to any Tax Returns of the
Borrowers are currently in effect or are currently proposed. Each of the
Borrowers has collected or withheld and paid over to the proper governmental or
regulatory bodies all amounts required to be so collected or withheld and paid
over under all applicable Laws. No action, suit, proceeding, investigation,
audit, claim or assessment is presently pending or, to the Borrowers' knowledge,
threatened with regard to any Taxes that relate to the Borrowers for which any
of the Borrowers is or could reasonably be expected to be liable. There is no
unresolved claim by a taxing authority in any jurisdiction where any of the
Borrowers does not anticipate to file Tax Returns that it is or could reasonably
be expected to be subject to taxation by such jurisdiction. There are no Liens
for Taxes (other than for Taxes not yet due and payable) upon any assets or
property of the Borrowers. The Lender acknowledges that the foregoing
representations and warranties made in this Section 3.6 do not apply in respect
of Accurate Components Inc. ("Accurate") or Market Trading Concepts Inc.
("Market Trading") (recently acquired, wholly-owned subsidiaries of Borrowers).
The Lender further acknowledges that the representations and warranties made in
respect of Accurate and Market Trading as to Tax matters in that certain Stock
Purchase Agreement by and between Borrowers, Accurate, Market Trading and
Anthony Arena, dated November 12, 1999, have been made available to the Lender
for its review and, to the Borrowers' knowledge, they are true and correct.

None of the Borrowers (i) has made any other election pursuant to the Code other
than elections that relate solely to matters of accounting, depreciation, or
amortization, that could reasonably be expected to have an adverse effect on,
its financial condition, its business as presently conducted or presently
proposed to be conducted or any of its properties or assets; and (ii) has at any
time filed a consent to the application of Section 341(f)(2) of the Code to any
property or assets held, acquired or to be acquired by it. None of the Borrowers
is a party to any tax allocation or sharing agreement, and has no liability for
the Taxes of any other entity under Treasury Regulation (S) 1.1502-6 (or any
similar provision of state, local or foreign law), as a transferee or successor,
by contract, or otherwise.

3.7   Compliance with Laws; Permits.  Except as set forth on Schedule 3.7
      -----------------------------                          ------------

Laws applicable to it or any of its properties or operations, including, without
limitation, all Environmental Laws. None of the Borrowers has received any
notice of its violation or alleged violation of any Law. Each of the borrowers
has all Permits necessary for the conduct of its business and operations as
currently

                                       7
<PAGE>

conducted. All material Permits of the Borrowers are valid and in full force and
effect. No violations have occurred in respect of any such Permit and no action
or proceeding is pending nor, to the Borrowers' knowledge, threatened to revoke
or limit any such Permit.

3.8   No Breach; Consents; Payments.  The execution, delivery and performance of
      -----------------------------
this Agreement and all other agreements or certificates referred to in or
contemplated by this Agreement by the Borrowers and the consummation of the
transactions contemplated hereby and thereby will not (i) result in any Lien
upon any property of the Borrowers (other than the Lien in favor of the Lender
pursuant to the Security Documents); or (ii) violate, conflict with or otherwise
result in the breach of any of the terms and conditions of, result in a material
modification of or accelerate or trigger the rights of any person under, or
constitute (or, with the giving of notice or lapse of time or both, would
constitute) a default or termination under (a) any of the Borrowers Constituent
Documents; (b) any instrument, contract or other agreement to which any of the
Borrowers is a party or by or to which any of the Borrowers or any of its
property is bound or subject; (c) any Law applicable to Borrowers or any of its
property or operations; or (d) any Permit. Except as set forth in Schedule 3.8,
                                                                  ------------
no Consent is required on the part of the Borrowers in connection with the
execution, delivery or performance of this Agreement, the Security Documents or
the consummation of the transactions contemplated hereby. There are no payments,
Liabilities or obligations under or pursuant to any Law or contract or other
agreement to which any of the Borrowers is a party which are required to be made
or performed by the Borrowers to any person, arising out of or as a result of
the transactions contemplated by this Agreement.

3.9   Litigation; Claims.  Except as set forth on Schedule 3.9 hereto, there are
      ------------------                          ------------
no suits or actions, administrative, arbitration or other proceedings or
governmental investigations pending or, to the Borrowers' knowledge, threatened
against or affecting the Borrowers or any of their property or assets. Except as
set forth on Schedule 3.9, to the Borrowers' knowledge, no person has notified
             ------------
the Borrowers or any of their affiliates of a material claim against the
Borrowers alleging any personal property or economic injury, loss or damage
incurred as a result of or relating to the use of any products sold by or on
behalf of, or services rendered by, the Borrowers. There is no judgment, order,
injunction, decree or award against Borrowers which is not satisfied and remains
outstanding.

3.10  Employment Matters. The  Borrowers have not at any time during the last
      ------------------
three (3) years had, nor, to the Borrowers' knowledge, is there now threatened,

similar occurrence. There are no material

                                       8
<PAGE>

controversies or grievances pending or, to the Borrowers' knowledge, threatened
between the Borrowers and any of their employees. No union or other collective
bargaining unit has been certified or formally recognized by the Borrowers.

3.11  Material Agreements. Each of the Borrowers is in compliance with the terms
      -------------------
and conditions of its material contracts, except where the failure to be in such
compliance could not reasonably be expected to have a material adverse effect on
the business, operations, assets, or condition (financial or otherwise) of the
Borrowers, taken as a whole.

3.12  Real Estate.  The Borrowers do not own, in fee or otherwise, or have the
      -----------
right or obligation to acquire any real property or buildings. Each of the
leases, subleases and other agreements pursuant to which the Borrowers occupy

creates a good and valid leasehold estate in the property leased thereby, and
Borrowers are in material compliance with the provisions of each such agreement

thereunder.

      -----------------------------
right, title and interest in or valid and binding rights under contract to use
all items of Borrowers Intangible Property (as defined below) material to, or
necessary to conduct, the business of the Borrowers as presently conducted or
contemplated to be conducted. None of the Borrowers Intangible Property (other
than any patents and patent rights) materially infringes upon or violates any
rights owned or held by any other person. To the Borrowers' knowledge, none of
the patents and patent rights included in the Borrowers Intangible Property
materially infringes upon or violates any rights owned or held by any other
person. There is not pending nor, to the Borrowers' knowledge, threatened any
claim, suit or action against the Borrowers contesting or challenging the rights
of the Borrowers in or to any of the Borrowers Intangible Property or the
validity of any of the Borrowers Intangible Property. To Borrowers' knowledge,
there is no material infringement upon or unauthorized use of any of the
Borrowers Intangible Property owned by the Borrowers by any third party. None of
the Borrowers is in default (or, with the giving of notice or lapse of time or
both, would be in default) under any contract to use the Borrowers Intangible
Property. None of the Borrowers (nor any associate thereof) nor any officer,
director or affiliate or immediate family member, as the case may be, thereof
has any right to or interest in any of the Borrowers Intangible Property,

in respect of any use or transfer thereof.

business of the Borrowers, in each such case, including all forms (e.g.,
                                                                   ----
electronic media, computer disks, etc.) in which such items are recorded.

3.14  Title to Properties and Assets.  Each of the Borrowers has good title to
      ------------------------------
all of the property and assets owned or purported to be owned by it which are
reflected as assets on its balance sheet and those not so reflected on its
balance sheet because not required to be reflected thereon, but which are used
in the Borrowers' business (except for inventory or other assets disposed of in
the ordinary course of business consistent with past practice since the date of
such Borrower's most recent balance sheet), free and clear of any Lien, except

   -------------
of business, no person has any written or oral agreement, option, understanding,
commitment or any right or privilege to purchase, lease or license any of the
Borrowers' property or assets. None of the Liens set forth on Schedule 3.14

31, 1999.

      ----------------------
3(3) of ERISA) maintained by the Borrowers (or any affiliate thereof) or under
which the Borrowers have any obligations (other than obligations to make current
wage or salary payments) in respect of any of the employees of the Borrowers or
their beneficiaries (each individually, a "Borrowers Employee Benefit Plan" and
collectively, the "Borrowers Employee Benefit Plans") have complied in all
material respects in form, operation and administration with their respective
provisions, any applicable provisions of ERISA, the Code, and all other
applicable Laws. All contributions to and payments from the Borrowers Employee
Benefit Plans which have been

<PAGE>

required to be made in accordance with the provisions of the Borrowers Employee
Benefit Plans and, where applicable, ERISA and the Code have been made or are
adequately accrued and reflected on the books and records of the Borrowers.
There are no unfunded Liabilities in respect of any such Borrowers Employee
Benefit Plan. Neither the Borrowers, nor, to the Borrowers' knowledge, any of
its officers, employees or agents has committed any breach of fiduciary
responsibility with respect to the Borrowers Employee Benefit Plans to which
ERISA is applicable which could subject the Borrowers to any Liability under
ERISA. None of the Borrowers is and has ever been obligated to make

               ordinary course of the Borrowers business.

          (b)       Instruments/Chattel Paper. If any amount payable under or in

                    -------------------------------
               Lender such agreements, assignments or instruments (including
               affidavits, notices, reaffirmations and amendments and
               restatements of existing documents, as the Lender may reasonably
               request) and do all such other things as the Lender may
               reasonably deem necessary or appropriate (i) to assure to the
               Lender its security interests hereunder, including such financing
               statements (including renewal statements) or amendments thereof
               or supplements thereto or other instruments as the Lender may
               from time to time reasonably request in order to perfect and
               maintain the security interests granted hereunder in accordance
               with the UCC, (ii) to consummate the transactions contemplated
               hereby and (iii) to otherwise protect and assure the Lender of
               its rights and interests hereunder. To that end, each Obligor
               agrees that the Lender may file one or more financing statements
               disclosing the Lender's security interest in any or all of the
               Collateral of such Obligor without, to the extent permitted by
               law, such Obligor's signature thereon, and further each Obligor
               also hereby irrevocably makes, constitutes and appoints the
               Lender, its nominee or any other person whom the Lender may
               designate, as such Obligor's attorney in fact with full power and
               for the limited purpose to sign in the name of such Obligor any
               such financing statements, or amendments and supplements to
               financing statements, renewal financing statements, notices or
               any similar documents which in the Lender's reasonable discretion
               would be necessary, appropriate or convenient in order to perfect
               and maintain perfection of the security interests granted
               hereunder, such power, being coupled with an interest, being and
               remaining irrevocable so long as the Credit Agreement is in
               effect or any amounts payable thereunder or under any other Loan
               Document, shall remain outstanding. Each Obligor hereby agrees
               that a carbon, photographic or other reproduction of this
               Security Agreement or any such financing statement is sufficient
               for filing as a financing statement by the Lender without notice
               thereof to such Obligor wherever the Lender may in its sole
               discretion desire to file the same. In the event for any reason
               the law of any jurisdiction other than New York becomes or is
               applicable to the Collateral of any Obligor or any part thereof,
               or to any of the Secured Obligations, such Obligor agrees to
               execute and deliver all such instruments and to do all such other
               things as the Lender in its sole discretion reasonably deems
               necessary or appropriate to preserve, protect and enforce the
               security interests of the Lender under the law of such other
               jurisdiction (and, if an Obligor shall fail to do so promptly
               upon the reasonable request of the Lender, then the Lender may
               execute any and all such requested documents on behalf of such
               Obligor pursuant to the power of attorney granted hereinabove).
               If any Collateral is in the possession or control of an Obligor's
               agents and the Lender so requests, such Obligor agrees to notify
               such agents in writing of the Lender's security interest therein
               and, upon the Lender's request, instruct them to hold all such
               Collateral for the Lender's account and subject to the Lender's
               instructions. Each Obligor agrees to mark its
<PAGE>

                                                                               6

               books and records to reflect the security interest of the Lender
               in the Collateral.

          (e)       Treatment of Accounts. Not grant or extend the time for
                    ---------------------
               payment of any Account, or compromise or settle any Account for
               less than the full amount thereof, or release any person or
               property, in whole or in part, from payment thereof, or allow any
               credit or discount thereon, other than as normal and customary in
               the ordinary course of an Obligor's business.

          (f)       Insurance. Insure, repair and replace the Collateral of such
                    ---------
               Obligor as set forth in the Credit Agreement. All insurance
               proceeds shall be subject to the security interest of the Lender
               hereunder.

     6.        Advances by Lenders. On failure of any Obligor to materially
               -------------------
          perform any of the covenants and agreements contained herein, the
          Lender may, upon written notice to Obligor and after a reasonable
          opportunity to cure (unless, in the Lender's reasonable judgment, a
          cure period could have a detrimental effect on the value of the
          security) at its sole option and in its sole discretion, perform the
          same and in so doing may expend such sums as the Lender may reasonably
          deem advisable in the performance thereof, including, without
          limitation, the payment of any insurance premiums, the payment of any
          taxes, a payment to obtain a release of a Lien or potential Lien,
          expenditures made in defending against any adverse claim and all other
          expenditures which the Lender may make for the protection of the
          security hereof or which may be compelled to make by operation of law.
          All such sums and amounts so expended shall be repayable by the
          Obligors on a joint and several basis promptly upon timely notice
          thereof and demand therefor, shall constitute additional Secured
          Obligations and shall bear interest from the date said amounts are
          expended at the Default Rate. No such performance of any covenant or
          agreement by the Lender on behalf of any Obligor, and no such advance
          or expenditure therefor, shall relieve the Obligors of any default
          under the terms of this Security Agreement or the other Loan
          Documents. The Lender may make any payment hereby authorized in
          accordance with any bill, statement or estimate procured from the
          appropriate public office or holder of the claim to be discharged
          without inquiry into the accuracy of such bill, statement or estimate
          or into the validity of any tax assessment, sale, forfeiture, tax
          lien, title or claim except to the extent such payment is being
          contested in good faith by an Obligor in appropriate proceedings and
          against which adequate reserves are being maintained in accordance
          with GAAP.

     7.        Events of Default.
               -----------------

The occurrence of an event which under the Credit Agreement would constitute an
Event of Default shall be an Event of Default hereunder (an "Event of Default").
                                                             ----------------

     8.        Remedies.

                                                                               7

          (a)       General Remedies. Upon the occurrence of an Event of Default
                    ----------------
               and during continuation thereof, and after written notice by the
               Lender to the Obligors, the Lender shall have, in addition to the
               rights and remedies provided herein, in the Loan Documents, or by
               law (including, but not limited to, the rights and remedies set
               forth in the Uniform Commercial Code of the jurisdiction
               applicable to the affected Collateral), the rights and remedies
               of a secured party under the UCC (regardless of whether the UCC
               is the law of the jurisdiction where the rights and remedies are
               asserted and regardless of whether the UCC applies to the
               affected Collateral), and further, the Lender may, with or
               without judicial process or the aid and assistance of others, (i)
               enter on any premises on which any of the Collateral may be
               located and, without resistance or interference by the Obligors,
               take possession of the Collateral, (ii) dispose of any Collateral
               on any such premises, (iii) require the Obligors to assemble and
               make available to the Lender at the expense of the Obligors any
               Collateral at any place and time designated by the Lender which
               is reasonably convenient to both parties, (iv) remove any
               Collateral from any such premises for the purpose of effecting
               sale or other disposition thereof, and/or (v) without demand and
               without advertisement, notice, hearing or process of law, all of
               which each of the Obligors hereby waives to the fullest extent
               permitted by law, at any place and time or times, sell and
               deliver any or all Collateral held by or for it at public or
               private sale, by one or more contracts, in one or more parcels,
               for cash, upon credit or otherwise, at such prices and upon such
               terms as the Lender deems advisable, in its sole discretion
               (subject to any and all mandatory legal requirements). In
               addition to all other sums due the Lender with respect to the
               Secured Obligations, the Obligors shall pay the Lender all
               reasonable documented costs and expenses incurred by the Lender
               including, but not limited to, reasonable attorneys' fees and
               court costs, in obtaining or liquidating the Collateral, in
               enforcing payment of the Secured Obligations, or in the
               prosecution or defense of any action or proceeding by or against
               the Lender or the Obligors concerning any matter arising out of
               or connected with this Security Agreement, any Collateral or the
               Secured Obligations, including, without limitation, any of the
               foregoing arising in, arising under or related to a case under
               the Bankruptcy Code. To the extent the rights of notice cannot be
               legally waived hereunder, each Obligor agrees that any
               requirement of reasonable notice shall be met if such notice is
               personally served on or mailed, postage prepaid, to the Borrower
               in accordance with the notice provisions of Section 9.7 of the
                                                           -----------
               Credit Agreement at least 10 days before the time of sale or
               other event giving rise to the requirement of such notice. The
               Lender shall not be obligated to make any sale or other
               disposition of the Collateral regardless of notice having been
               given. To the extent permitted by law, the Lender may be a
               purchaser at any such sale. To the extent permitted by applicable
               law, each of the Obligors hereby waives all of its rights of
               redemption with respect to any such sale. Subject to the
               provisions of applicable law, the Lender may postpone or cause
               the postponement of the sale of all or any portion of the
               Collateral by announcement at the time and place of such sale,
               and such sale
<PAGE>

                                                                               8

               may, without further notice, to the extent permitted by law, be
               made at the time and place to which the sale was postponed, or
               the Lender may further postpone such sale by announcement made at
               such time and place.

          (b)       Remedies relating to Accounts. Upon the occurrence of an
                    -----------------------------
               Event of Default and during the continuation thereof, whether or
               not the Lender has exercised any or all of its rights and
               remedies hereunder, each Obligor will promptly upon request of
               the Lender instruct all account debtors to remit all payments in
               respect of Accounts to a mailing location selected by the Lender.
               In addition, upon the occurrence and during the continuation of
               an Event of Default, the Lender or its designee may notify any
               Obligor's customers and account debtors that the Accounts of such
               Obligor have been assigned to the Lender or of the Lender's
               security interest therein, and may (either in its own name or in
               the name of an Obligor or both) demand, collect (including
               without limitation by way of a lockbox arrangement), receive,
               take receipt for, sell, sue for, compound, settle, compromise and
               give acquittance for any and all amounts due or to become due on
               any Account, and, in the Lender's discretion, file any claim or
               take any other action or proceeding to protect and realize upon
               the security interest of the Lender in the Accounts. Each Obligor
               acknowledges and agrees that the Proceeds of its Accounts
               remitted to or on behalf of the Lender in accordance with the
               provisions hereof shall be solely for the Lender's own
               convenience and that such Obligor shall not have any right, title
               or interest in such Proceeds except as expressly provided herein.
               The Lender shall have no liability or responsibility to any
               Obligor for acceptance of a check, draft or other order for
               payment of money bearing the legend "payment in full" or words of
               similar import or any other restrictive legend or endorsement or
               be responsible for determining the correctness of any remittance.
               Each Obligor hereby agrees to indemnify the Lender from and
               against all liabilities, damages, losses, actions, claims,
               judgments, costs, expenses, charges and reasonable attorneys'
               fees suffered or incurred by the Lender because of the
               maintenance of the foregoing arrangements, except as relating to
               or arising out of the gross negligence or willful misconduct or
               unlawful conduct of the Lender or its officers or employees. In
               the case of any investigation, litigation or other proceeding,
               the foregoing indemnity shall be effective whether or not such
               investigation, litigation or proceeding is brought by an Obligor,
               its directors, shareholders or creditors or the Lender or any
               other Person.

          (c)       Access. In addition to the rights and remedies hereunder,
                    ------
               upon the occurrence of an Event of Default and during the
               continuance thereof, the Lender shall have the right to
               reasonably enter and remain upon the various premises of the
               Obligors without cost or charge to the Lender, and use the same,
               together with materials, supplies, books and records of the
               Obligors for the purpose of collecting and liquidating the
               Collateral, or for preparing for sale and conducting the sale of
               the Collateral, whether by foreclosure, auction or otherwise. In
               addition, the Lender may remove
<PAGE>

                                                                               9

               Collateral, or any part thereof, from such premises and/or any
               records with respect thereto, in order to effectively collect or
               liquidate such Collateral.

          (d)       Nonexclusive Nature of Remedies. Failure by the Lender to
                    -------------------------------
               exercise any right, remedy or option under this Security
               Agreement, any other Loan Document, or as provided by law, or any
               delay by the Lender in exercising the same, shall not operate as
               a waiver of any such right, remedy or option. No waiver hereunder
               shall be effective unless it is in writing, signed by the party
               against whom such waiver is sought to be enforced and then only
               to the extent specifically stated, which in the case of the
               Lender shall only be granted as provided herein. To the extent
               permitted by law, neither the Lender nor any party acting as
               attorney for the Lender, shall be liable hereunder for any acts
               or omissions or for any error of judgment or mistake of fact or
               law other than their gross negligence or willful misconduct or
               unlawful conduct hereunder. The rights and remedies of the Lender
               under this Security Agreement shall be cumulative and not
               exclusive of any other right or remedy which the Lender may have.

          (e)       Retention of Collateral. In addition to the rights and
                    -----------------------
               remedies hereunder, upon the occurrence of an Event of Default
               and during the continuation thereof, the Lender may, after
               providing the notices required by Section 9-505(2) of the UCC and
               otherwise complying with the requirements of applicable law of
               the relevant jurisdiction, to the extent the Lender is in
               possession of any of the Collateral, retain the Collateral in
               satisfaction of the Secured Obligations. Unless and until the
               Lender shall have provided such notices, however, the Lender
               shall not be deemed to have retained any Collateral in
               satisfaction of any Secured Obligations for any reason.

          (f)       Deficiency. In the event that the proceeds of any sale,
                    ----------
               collection or realization are insufficient to pay all amounts to
               which the Lender is legally entitled, the Obligors shall be
               jointly and severally liable for the deficiency, together with
               interest thereon at the Default Rate, together with the
               reasonable costs of collection and the reasonable fees of any
               attorneys employed by the Lender to collect such deficiency. Any
               surplus remaining after the full payment and satisfaction of the
               Secured Obligations shall be returned to the Obligors or to
               whomsoever a court of competent jurisdiction shall determine to
               be entitled thereto.

     9.        Additional Rights of the Lender.
               -------------------------------

          (a)       Power of Attorney. In addition to other powers of attorney
                    -----------------
               contained herein, each Obligor hereby designates and appoints the
               Lender, and each of its designees, as attorney-in-fact of such
               Obligor, irrevocably and with power of substitution (to the
               extent permitted by applicable law), with authority to take any
               or all of the following actions upon the occurrence and during
               the continuance of an Event of Default:
<PAGE>

                                                                              10

          (i)            to demand, collect, settle, compromise, adjust, give
                  discharges and releases, all as the Lender may reasonably
                  determine;

          (ii)           to commence and prosecute any actions at any court for
                  the purposes of collecting any Collateral and enforcing any
                  other right in respect thereof;

          (iii)          to defend, settle or compromise any action brought and,
                  in connection therewith, give such discharge or release as the
                  Lender may deem reasonably appropriate;

                  Obligor and endorse checks, notes, drafts, acceptances, money

                  of, or otherwise deal with or exercise rights in respect of,
                  any Collateral or the goods or services which have given rise
                  thereto, as fully and completely as though the Lender were the
                  absolute owner thereof for all purposes;

          (vi)           adjust and settle claims under any insurance policy
                  relating thereto;

          (vii)          execute and deliver all assignments, conveyances,

               This power of attorney is a power coupled with an interest and
     shall be irrevocable for so long as any of the Secured Obligations remain
     outstanding or any Loan Document is in effect.  The Lender shall be under
     no duty to exercise or withhold the exercise of any of the rights, powers,
     privileges and options expressly or implicitly granted to the Lender in
     this Security Agreement, and shall not be liable for any failure to do so
     or any delay in doing so.  The Lender shall not be liable for any act or
     omission or for any error of judgment or any mistake of fact or law in its
     individual capacity or its capacity as attorney-in-fact except acts or
     omissions resulting from its gross negligence or willful misconduct or
     unlawful conduct.  This power of attorney is conferred on the Lender solely
     to protect, preserve and realize upon its security interest in the
     Collateral.

          (b)       The Lender's Duty of Care. Other than the exercise of
                    -------------------------
               reasonable care to assure the safe custody of the Collateral
               while being held by the Lender hereunder, the Lender shall have
               no duty or liability to preserve rights pertaining thereto, it
               being understood and agreed that the Obligors shall be
               responsible for preservation of all rights in the Collateral, and
               the Lender shall be relieved of all responsibility for the
               Collateral upon surrendering it or tendering the surrender of it
               to the Obligors. The Lender shall be deemed to have exercised
               reasonable care in the custody and preservation of the Collateral
               in its possession if the Collateral is accorded treatment
               substantially equal to that which the Lender accords its own
               property, which shall be no less than the treatment employed by a
               reasonable and prudent Lender in the industry, it being
               understood that the Lender shall not have responsibility for
               taking any necessary steps to preserve rights against any parties
               with respect to any of the Collateral.

     10.       Application of Proceeds. Upon the occurrence and during the
               -----------------------
          continuance of an Event of Default, any payments in respect of the
          Secured Obligations and any proceeds of the Collateral, when received
          by the Lender in cash or its equivalent, will be applied in reduction
          of the Secured Obligations and each Obligor irrevocably waives the
          right to direct the application of such payments and proceeds and
          acknowledges and agrees that the Lender shall have the continuing and
          exclusive right to apply and reapply any and all such payments and
          proceeds in the Lender's sole discretion, notwithstanding any entry to
          the contrary upon any of its books and records.

     11.       Costs of Counsel. If at any time hereafter, whether upon the
               ----------------
          occurrence of an Event of Default or not, the Lender employs counsel
          to prepare amendments, waivers or consents with respect to this
          Security Agreement, or to take action or make a response in or with
          respect to any legal proceeding relating to this Security Agreement or
          relating to the Collateral, or to protect the Collateral or exercise
          any rights or remedies under this Security Agreement or with respect
          to the Collateral, then the Obligors agree to promptly pay upon demand
          any and all such reasonable documented costs and expenses of the
          Lender all of which costs and expenses shall constitute Secured
          Obligations hereunder.

     12.       Continuing Agreement.
               --------------------

          (a)       This Security Agreement shall be a continuing agreement in
               every respect and shall remain in full force and effect so long
               as any of the Secured Obligations remain outstanding or any Loan
               Document is in effect. Upon such payment and termination, this
               Security Agreement shall be automatically terminated and the
               Lender shall, upon the request and at the expense of the
               Obligors, forthwith release all of its liens and security
               interests hereunder and shall execute and deliver all UCC
               termination statements and/or other documents reasonably
               requested by the Obligors evidencing such termination.
               Notwithstanding the foregoing all releases and indemnities
               provided hereunder shall survive termination of this Security
               Agreement; but with respect to the indemnities for a period of 24
               months following such termination.

          (b)       This Security Agreement shall continue to be effective or be
               automatically reinstated, as the case may be, if at any time
               payment, in whole or in part, of any of the Secured Obligations
               is rescinded or must otherwise be restored or returned by the
               Lender as a preference, fraudulent conveyance or otherwise under
               any bankruptcy, insolvency or similar law, all as though such
               payment had not been made; provided that in the event payment of
               all or any part of the Secured Obligations is rescinded or must
               be restored or returned, all reasonable costs and expenses
               (including without limitation any reasonable legal fees and
               disbursements) incurred by the Lender in defending and enforcing
               such reinstatement shall be deemed to be included as a part of
               the Secured Obligations.

     13.       Amendments; Waivers; Modifications. This Security Agreement and
               ----------------------------------
          the provisions hereof may not be amended, waived, modified, changed,
          discharged or terminated except as set forth in Section 9.3 of the
                                                          -----------
          Credit Agreement.

     14.       Successors in Interest. This Security Agreement shall create a
               ----------------------
          continuing security interest in the Collateral and shall be binding
          upon each Obligor, its successors and assigns and shall inure,
          together with the rights and remedies of the Lender hereunder, to the
          benefit of the Lender and its successors and permitted assigns;
          provided, however, that none of the Obligors may assign its rights or
          --------  -------
          delegate its duties hereunder without the prior written consent of the
          Lender, and the Lender may not assign its rights or delegate its
          duties hereunder, other than to an affiliate of the Lender, without
          the prior written consent of the Obligors. To the fullest extent
          permitted by law, each Obligor hereby releases the Lender, and its
          successors and assigns, from any liability for any act or omission
          relating to this Security Agreement or the Collateral, except for any
          liability arising from the gross negligence or willful misconduct or
          unlawful conduct of the Lender, or its officers or employees.

     15.       Notices. All notices required or permitted to be given under this
               -------
          Security Agreement shall be in conformance with Section 9.7 of the
                                                          -----------
          Credit Agreement.

     16.       Counterparts. This Security Agreement may be executed in any
               ------------
          number of counterparts, each of which where so executed and delivered
          shall be an original, but all of which shall constitute one and the
          same instrument. It shall not be necessary in making proof of this
          Security Agreement to produce or account for more than one such
          counterpart signed by each of the parties.

     17.       Headings. The headings of the sections and subsections hereof are
               --------

     18.       Governing Law; Submission to Jurisdiction; Venue.
               ------------------------------------------------

          (a)  This Security Agreement shall be construed in accordance with and

               execution or otherwise) with respect to itself or its property,
               or (ii) any objection to the laying of the venue or of an

               Agreement, such Obligor hereby irrevocably waives such immunity
               or objection in respect of any suit, action or proceeding arising
               out of or relating to this Security Agreement.

     19.       Waiver of Jury Trial. EACH OF THE PARTIES OF THIS SECURITY
               --------------------
          AGREEMENT HEREBY KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVES ANY
          RIGHTS IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION
          HEREON OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS SECURITY
          AGREEMENT. EACH SUCH PARTY HEREBY ACKNOWLEDGES THAT IT WAS REPRESENTED
          BY COUNSEL IN ITS ENTERING INTO THIS SECURITY AGREEMENT AND IT WAS
          EXPLAINED THE MEANING OF THIS WAIVER OF JURY TRIAL.

     20.       Severability. If any provision of this Security Agreement is
               ------------
          determined to be illegal, invalid or unenforceable, such provision
          shall be fully severable and the remaining provisions shall remain in
          full force and effect and shall be construed without giving effect to
          the illegal, invalid or unenforceable provisions.

     21.       Entirety. This Security Agreement and the other Loan Documents
               --------
          constitute the entire contract between the parties relative to the

          Security Agreement and the other Loan Documents.

     22.       Survival. All representations and warranties of the Obligors
               --------
          hereunder shall survive the execution and delivery of this Security
          Agreement, the other Loan Documents, the delivery of the Note and the
          making of the Loan so long as any of the Secured Obligations remain
          outstanding or any other Loan Document is in effect.

     23.       Other Security. To the extent that any of the Secured Obligations
               --------------
          are now or hereafter secured by property other than the Collateral
          (including, without limitation, real property and securities owned by
          an Obligor), or by a guarantee, endorsement or property of any other
          Person, then the Lender shall have the right to proceed against such
          other property, guarantee or endorsement upon the occurrence of any
          Event of Default and during the continuation, and the Lender shall
          have the right, in its sole discretion, to determine which rights,
          security, liens, security interests or remedies the Lender shall at
          any time pursue, relinquish, subordinate, modify or take with respect
          thereto, without in any way modifying or affecting any of them or any
          of the Lender's rights or the Secured Obligations under this Security

     24.       Joint and Several Obligations of Obligors.
               -----------------------------------------

          (a)       Each of the Obligors is accepting joint and several
               liability hereunder in consideration of the financial
               accommodation to be provided by the Lender under the Credit
               Agreement, for the mutual benefit, directly and indirectly, of
               each of the Obligors and in consideration of the undertakings of
               each of the Obligors to accept joint and several liability for
               the obligations of each of them.

          (b)       Each of the Obligors jointly and severally hereby
               irrevocably and unconditionally accepts, not merely as a surety
               but also as a co-debtor, joint and several liability with the
               other Obligors with respect to the payment and performance of all
               of the Secured Obligations arising under this Security Agreement,
               and the other Loan Documents, it being the intention of the
               parties hereto that all the Obligations shall be the joint and

               herein or in any other of the Loan Documents, to the extent the
               obligations of an Obligor shall be adjudicated to be invalid or
               unenforceable for any reason (including, without limitation,
               because of any applicable state or federal law relating to
               fraudulent conveyances or transfers) then the obligations of each
               Obligor hereunder shall be limited to the maximum amount that is
               permissible under applicable law (whether federal or state and
               including, without limitation, the Bankruptcy Code).

Each of the parties hereto has caused a counterpart of this Security Agreement
to be duly executed and delivered as of the date first above written.
