SUMMARY OF

DYNAMIC DETAILS, INCORPORATED

SENIOR MANAGEMENT BONUS PROGRAM

1. Purpose and Effective Date. The bonus program, effective as of January 21, 2004, shall
be known as the Dynamic Details Incorporated Senior Management Bonus Program (the “Bonus Program”).
It is a performance-based bonus program for the benefit of a select group of employees of (i) DDi
Corp., a Delaware corporation (“DDi Corp.”); (ii) Dynamic Details, Incorporated, a California
corporation and DDi Corp.’s principal operating North American subsidiary (“Dynamic Details”); and
any of the other North American subsidiaries of DDi Corp. (“Participants”) who are selected for
participation as provided herein. The Bonus Program is intended to qualify as a compensation or
bonus plan that is exempt from the application of the Employee Retirement Income Security Act of
1974, as amended, by reason of Section 3 of such Act. Unless otherwise noted, the term the
“Company” shall refer to DDi Corp. and/or any of its North American subsidiaries, as applicable.

2. Eligibility and Participation. Eligibility and participation shall be at the sole
discretion of DDi Corp. In order to become a Participant eligible to receive benefits, an employee
must be selected for participation in the sole discretion of the Compensation Committee of the
Board of Directors of DDi Corp (the “Compensation Committee”). Management of DDi Corp. will notify
those employees it determines to be eligible for participation in the Bonus Program in writing of
their participation.

3. Performance Bonus. The Bonus Program is designed to encourage Participants to perform
in a satisfactory manner over the course of calendar year 2004.

     a. Calculation. The performance bonus payable to Participants who remain employed by
the Company at December 31, 2004 (the “Qualification Date”) is a specified percentage of Base
Salary (the annual base salary of the Participant as measured as of the Qualification Date) based
upon the achievement of EBITDA from DDi Corp.’s consolidated North American operations less the
total amount of bonus payments awarded under the Bonus Program (“Net EBITDA”). For purposes of the
Bonus Program, EBITDA shall not include the impact of non-recurring charges or gains, consistent
with the approach used for reporting “Adjusted EBITDA” in the DDi Corp.’s quarterly earnings
releases. For fiscal year 2004, the target Net EBITDA shall be determined by the Compensation
Committee of the Board of Directors. Participant’s bonus shall be determined as follows: using
the table below, take the applicable “Net EBITDA %” (actual Net EBITDA measured by DDi Corp.
divided by target net EBITDA) then calculate the product of the corresponding “Award %” multiplied
by the Participant’s Base Salary.

1

 

	 	 	 
	Net EBITDA %	 	Award %
	< 80%
	 	0%
	> 80%, but < 85%
	 	10%
	> 85%, but < 90%
	 	20%
	> 90%, but < 95%
	 	30%
	> 95%, but < 100%
	 	40%
	> 100%
	 	50%

     b. Form and Time of Payment. The bonus payable to a Participant hereunder (“Bonus”)
shall be paid after (i) the completion of the audit of the financial statements for the year ended
December 31, 2004 and (ii) actual Net EBITDA for 2004 has been calculated by senior management of
DDi Corp. and certified by the Chief Financial Officer of DDi Corp. The Bonus shall be paid in a
lump sum and shall be subject to payroll taxes and other withholding according to standard payroll
practices of Dynamic Details.

     c. Satisfactory Performance Required. The Bonus is contingent on satisfactory service
through the Qualification Date (except as otherwise expressly set forth in section 4.c, below) and
on terms and conditions specified herein. Notwithstanding any provisions of the Bonus Program to
the contrary, the Company retains the right to reduce, eliminate or otherwise modify the Bonus for
any Participant if at any time during calendar year ended December 31, 2004 (the “Bonus Period”),
senior management of Dynamic Details, in their sole judgment, determines that such Participant’s
performance is substandard, provided (i) the Company gives the Participant written notice
of that determination and a reasonable period of time within which to improve his or her
performance, and (ii) the Participant fails to improve his or her performance to the Company’s
satisfaction within that time.

     d. Corporate Transactions and Change of Control. The obligations of the Bonus Program
shall be binding on a any employer that acquires, through a stock purchase or merger, or through an
asset purchase, or otherwise, part or all of DDi Corp. or an employer following a Change of
Control. A “Change of Control” means (i) the acquisition of 50 % or more of each class of the
outstanding shares of the Company by a third party which is not a member of a “Controlled Group”
(within the meaning of the Internal Revenue Code) including DDi Corp. (ii) a merger, consolidation
or other reorganization of DDi Corp. (other than reincorporation), if after giving effect to such
merger, consolidation, or other reorganization, the shareholders of DDi Corp. immediately prior to
such merger, consolidation, or other reorganization do not represent a majority in interest of the
holders of voting securities (on a fully diluted basis) with the ordinary power to elect directors
of the surviving entity after such merger, consolidation or other reorganization; or (iii) the sale
of all or substantially all of the assets of the DDi Corp. to a third party who is not a member of
a Controlled Group (within the meaning of the Internal Revenue Code) including DDi Corp.

4. Termination of Participation

     a. Events. A Participant’s participation in the Bonus Program shall automatically
terminate, without notice to or consent by such Participant, upon the first to occur of the
following events with respect to such Participant:

	 	1)  	Involuntary termination of employment;
	 
	 	2)  	Voluntary Resignation;
	 
	 	3)  	Death; or
	 
	 	4)  	Disability.

     b. Effect of Termination For Cause or Resignation without Good Reason. In the event
that, prior to the Qualification Date, a Participant’s employment is terminated by the Company for
Cause or a Participant voluntarily terminates employment with the Company other than for Good
Reason, the Participant shall forfeit his or her entire right to any Bonus hereunder.

     c. Effect of Other Events; Pro Rata Payments. Pro rata payments will be made only in
the following circumstances and calculated in the manner specified herein:

            1) Termination by the Company for reasons other than Cause, Termination because of Death or
Disability, or Resignation For Good Reason.

     In the event a Participant’s employment is terminated prior to the Qualification Date for any
reason other than Cause, by death or Disability or in the event that a Participant resigns for Good
Reason, the Participant shall be entitled to receive a pro-rata amount of the portion of the Bonus
calculated as the product of the Bonus (as determined pursuant to section 3.a above) multiplied by
a fraction, the numerator equal to the number days from January 1, 2004 through the termination
date of Participant’s employment with the Company, and the denominator being 366.

     In addition, the Company, in consultation with (and upon approval by) the Compensation
Committee, shall review the payments to be made to Participants who are terminated due to death or
Disability, and when appropriate, may award the full amount of the Bonus to such Participants
giving full consideration to the value contributed both before and during the Bonus Period.

            2) Employees on Leave. If a Participant is on an approved leave of absence during the Bonus
Period, he or she will receive a pro rata Bonus based on the time actually worked during the Bonus
Period, as calculated by senior management of DDi Corp. in its reasonable discretion.

            3) Promoted Employees. Participants who are hired or promoted to replace Participants
participating in the Bonus Program who voluntarily terminated their own employment or who were
terminated for Cause (as defined below) may be selected for participation and eligible for payments
under the Bonus Program on a pro-rata basis, at the sole

3

 

discretion of the Compensation Committee, if an officer of DDi Corp. (as such term is defined
under the Securities Exchange Act of 1934, as amended), and in all other cases by the senior
management of DDi Corp.

     d. Definitions. For purposes of the Bonus Program, the following terms shall have the
following meaning:

            1) “Cause”, with respect to any Participant (including those with Employment Agreements) shall
be defined as the Participant’s:

	 	(i)  	willful refusal to perform, in any material respect, his or her duties or
responsibilities for the Company;
	 
	 	(ii)  	material breach of his or her duties or responsibilities to the Company;
	 
	 	(iii)  	gross negligence or willful disregard in the performance of his or her duties
or responsibilities;
	 
	 	(iv)  	willful disregard, in any material respect, of any financial or other budgetary
limitations established in good faith by the Board of Directors of the Company, if
continuing after written notice;
	 
	 	(v)  	engaging in conduct that causes material and demonstrable injury, monetarily
or otherwise, to the Company, including, but not limited to, misappropriation or
conversion of the Company’s assets; or
	 
	 	(vi)  	conviction of or entry of a plea of nolo contendere to a felony.

            2) “Disability” means a physical or mental condition that renders the Participant unable to
perform the essential functions of his or her job with or without a reasonable accommodation for a
period of 180 consecutive days or more.

            3) “Good Reason” with respect to any Participant shall mean the occurrence of one or more of
the following with respect to such Participant: (i) a material reduction in compensation or
benefits (provided, however, that a reduction in salary that is both (x) made part of a
company-wide salary reduction and (y) no greater than the percentage reduction made for the
applicable salary level in the Company salary reduction of July 2001, shall be deemed to be
immaterial); (ii) involuntary relocation of primary work location more than 50 miles from the
current location; and/or (iii) any other event so defined in any applicable employment agreement.

5. Binding Authority. Subject to the review and approval of the Board of Directors of DDi

Bonus Program and shall not be subject to any appeal or review.

6. Source of Payments. Bonus Payments will be paid in cash from the general consolidated
funds of DDi Corp. No separate fund will be established.

7. Amendment or Termination. The Bonus Program may be amended, modified, suspended or
terminated by the Board of Directors of DDi Corp. or the Compensation Committee at any time and
without notice to or the consent of Participants.

8. Severability. If any term or condition of the Bonus Program shall be invalid or
unenforceable, the remainder of the Bonus Program shall not be affected thereby and shall continue
in effect and application to the fullest extent permitted by law.

9. No Employment Rights. Neither the establishment nor the terms of the Bonus Program
shall be held or construed to confer upon any employee the right to a continuation of employment by
the Company, nor constitute a contract of employment, express or implied. Subject to any
applicable employment agreement, the Company reserves the right to dismiss or otherwise deal with
any employee, including the Participants, to the same extent as though the Bonus Program had not
been adopted. Nothing in the Bonus Program is intended to alter the “AT-WILL” status of
Participants, it being understood that, except to the extent otherwise expressly set forth to the
contrary in a written employment agreement, the employment of any Participant can be terminated at
any time by either the Company or the employee with or without notice, with or without cause.

10. Transferability of Rights. The Company shall have the right to transfer its
obligations under the Bonus Program, with respect to one or more Participants, to any person,
including any purchaser of all or any part of the Company’s business. No Participant or spouse
shall have any right to commute, encumber, transfer or otherwise dispose of or alienate any present
or future right or expectancy which the Participant may have at any time to receive payments of
benefits hereunder, which benefits and the rights thereto are expressly declared to be
nonassignable and nontransferable, except to the extent required by law. Any attempt by a
Participant to transfer or assign a benefit or any rights granted hereunder shall (after
consideration of such facts as the Company deems pertinent) be grounds for terminating any rights
of the Participant to any portion of the Bonus Program benefits not previously paid.

11. Governing Law. The Bonus Program shall be construed, administered and enforced
according to the laws of the State of California.

shall only have recourse to the Collateral through the Collateral Agent and that

Persons signing such instrument or instruments.

            (b) The Collateral Agent shall be entitled to rely absolutely upon
an Action of the Requisite Parties, the Special Requisite Parties or the
Majority Secured Parties, as the case may be, if such Action purports to be
taken by or on behalf of such Requisite Parties, such Special Requisite Parties
or such Majority Secured Parties, as the case may be, and nothing in this
Section 2.2 or elsewhere in this Agreement shall be construed to require the
Collateral Agent to demonstrate that such Requisite Parties, such Special
Requisite Parties or such Majority Secured Parties, as the case may be, have
been authorized by the Note Holders, Northern, BofA and/or the holders of
Additional Future Debt, as applicable, to take any action which they purport to
be taking, the Collateral Agent being entitled to rely conclusively, and being

decline to follow any such direction if (i) the Collateral Agent, being advised
by counsel and acting in good faith, determines that the directed action is not
permitted by the terms of this Agreement or the Security Documents or is
unlawful or (ii) the Collateral Agent, being advised by counsel and acting in
good faith, is in reasonable doubt as to whether such directed action is
permitted by this Agreement or the Security Documents or would involve it in
personal liability unless the Collateral Agent shall be provided written
confirmation from the Requisite Parties or the Special Requisite Parties, as the
case may be, providing the Enforcement Notice that the Collateral Agent's
indemnity by the other Secured Parties contained in this Agreement would apply
without exception for such directed action (absent gross negligence and willful
misconduct of the Collateral Agent). All directions from the Requisite Parties
or the Special Requisite Parties, as the case may be, shall be as contemplated
and permitted by this Agreement and the applicable Security Document. The
Collateral Agent may rely on any such direction given to it by the Requisite

Guarantor, any holder of any Secured

exercise of specific remedies or to the exercise of remedies in general) from
the Requisite Parties or the Special Requisite Parties, as the case may be, the
Collateral Agent shall not, without the consent of the Requisite Parties or the
Special Requisite Parties, as the case may be, exercise remedies available to it

thereof.

      respective amounts owed to each Secured Party; and

                  (vi) sixth, after indefeasible payment in full of and

      creation of the Special Cash Collateral Account on which a reduction in
      Undrawn LC/Guaranty Exposure occurs by reason of either a drawing under
      any BofA Letter of Credit or a claim made by BofA against the Company on
      an IRB Bond Guaranty as certified to the Collateral Agent by BofA the
      Collateral Agent shall distribute from the Special Cash Collateral Account
      an amount (a "DISTRIBUTION AMOUNT") equal to the lesser of (1) the balance
      held by the Collateral Agent in the Special Cash Collateral Account and
      (2) all or a portion of the amount of such draw or claim, as certified to
      the Collateral Agent by BofA, which would have been received by BofA prior
      to such time had such draw or claim been made immediately prior to the
      first distribution made under Section 4.1(b) and the Secured Obligation
      resulting from such draw or claim represented a separate non-contingent
      Secured Obligation. The Distribution Amount shall be distributed to pay
      any outstanding non-contingent amount of non-contingent BofA Debt
      representing an increase in the amount of BofA Debt on account of such
      draw or claim. At such times as the Undrawn LC/Guaranty Exposure is
      reduced to zero, any amount remaining in the Special Cash Collateral
      Account, after the payment of all prior Distribution Amounts, shall be
      distributed as provided in clauses (iii), (iv), (v) and (vi) of Section
      4.1(b). BofA shall provide copies of each certificate delivered to the
      Collateral Agent under this Section 4.1(c) to the Company and each of the
      other Secured Parties when such certificate is delivered to the Collateral
      Agent.

                  (ii) Distributions of Proceeds Collateral. On any date after a
      Proceeds Deposit occurs, the Collateral Agent shall distribute from the
      Special Cash Collateral Account an amount (a "PROCEEDS DISTRIBUTION
      AMOUNT") equal to all or a portion of the amount of such Proceeds Deposit,
      in each case as requested in writing by BofA. The

<PAGE>
                                      -22-

      Proceeds Distribution Amount shall be distributed to BofA for application
      to the Reimbursement Agreement Debt. At such times as the Secured
      Obligations owing to BofA are reduced to zero, any amount remaining in the
      Special Cash Collateral Account attributable to Proceeds Deposits, shall
      be distributed as provided in clauses (iii), (iv), (v) and (vi) of Section
      4.1(b).

                  (iii) Investment of Special Cash Collateral Account. All
      amounts in the Special Cash Collateral Account shall be invested by the
      Collateral Agent in Permitted Investments, as directed in writing by the
      Company and all income on such Permitted Investments shall be retained in
      the Special Cash Collateral Account until all BofA Debt is paid in full
      and thereafter shall be distributed as provided in Section 4.1(b).

                  SECTION 4.2. NON-CASH DISTRIBUTIONS OR PROCEEDS. If the
Collateral Agent receives any non-cash distributions or proceeds in respect of
the Collateral, then, unless the Requisite Parties instruct the Collateral Agent
to the contrary, the Collateral Agent shall hold such non-cash distributions and
proceeds as Collateral upon the terms of this Agreement and the Security
Documents until converted to cash and thereupon applied or disbursed in
accordance with this Section 4; provided, however, that, if any non-cash
distribution is received by the Collateral Agent and is to be applied in
satisfaction of any Secured Obligation by operation of a plan of reorganization
under Chapter 11 of the federal Bankruptcy Code or otherwise as required by
applicable law, the Requisite Parties may, instead of awaiting the conversion of
such non-cash distribution to cash, direct the Collateral Agent to distribute
such non-cash distribution as provided in Section 4.1(b), except in respect of a
distribution under Section 4.1(b)(i).

                  SECTION 4.3. ADDITIONAL COLLATERAL. Each of BofA, each Note
Holder, Northern and each holder of Additional Future Debt hereby covenants and
agrees that it will not take, hold or suffer to exist any security interest in
or Lien on any assets as security for any of the Secured Obligations unless such
security interest or Lien is granted in favor of, or otherwise made available
to, the Collateral Agent for the benefit of BofA, the Note Holders, Northern and
the holders of Additional Future Debt as contemplated by this Agreement.

                  SECTION 4.4. CERTAIN NOTICES.

            (a) Each of BofA, each Note Holder, Northern and each holder of
Additional Future Debt hereby agrees to give written notice to the Collateral
Agent of any demand for payment in full of the Secured Obligations owing to the
demanding party, whether by acceleration of such obligations or otherwise (a
"DEMAND NOTICE"). Any Requisite Parties or Special Requisite Parties, as the
case may be, giving a Notice of Actionable Default or Enforcement Notice to the
Collateral Agent shall contemporaneously give a copy thereof to each of the
other Secured Parties.

            (b) Neither BofA, any Note Holder, Northern nor any holder of
Additional Future Debt shall incur liability of any kind should it, upon the
occurrence of any Event of Default, refrain from accelerating maturity or
otherwise demanding payment in full of any Secured Obligations owing to it, or
should it refrain from exercising any of its rights and

<PAGE>
                                      -23-

remedies against the Company, any Guarantor or any other obligor in respect of
the Secured Obligations.

                  SECTION 4.5. ENFORCEMENT.

            (a) The Collateral Agent shall (subject to the provisions of Section
3.2 and Section 5) take any such actions in the exercise of rights and remedies
under the Security Documents as are directed in an Enforcement Notice given by
the Requisite Parties or Special Requisite Parties, as the case may be, at any
time more than five (5) Business Days after a Notice of Actionable Default shall
have been given to a Responsible Officer of the Collateral Agent with respect to
the Event of Default that is the basis (or one of the bases) of the Enforcement
Notice. In the event the Collateral Agent shall have received conflicting
directions from the Special Requisite Parties and the Requisite Parties, it
shall follow the directions of the Requisite Parties, except to the extent that
such direction of the Requisite Parties would have the effect of rescinding or
nullifying any Enforcement Notice given by Special Requisite Parties, in which
case the Collateral Agent shall follow the directions of the Special Requisite
Parties set forth in such Enforcement Notice. In the event the Collateral Agent
shall receive conflicting directions as set forth in two or more Enforcement
Notices delivered by any one or more holders of Secured Obligations, each of
which constitutes Special Requisite Parties, it shall either (i) follow the
directions of the Requisite Parties or (ii) if no such directions shall have
been given by the Requisite Parties within thirty (30) Business Days from the
most recent directions so received from a group of holders constituting Special
Requisite Parties submit such matter to a court of competent jurisdiction to
establish the proper course of action it shall be required to take. It is
acknowledged that the Collateral Agent shall have no obligation to take any
action (including, without limitation, submitting such matter to court) unless
it has received security or indemnity as contemplated by Section 5.5(a).

            (b) BofA, each Note Holder, Northern and each holder of Additional
Future Debt agrees that it will promptly, and in any event within five (5)
Business Days after the request by one of the others (which request may be made
telephonically), advise the requesting party (telephonically, confirmed in
writing) as to the outstanding amount of Undrawn LC/Guaranty Exposure, other
BofA Debt, Note Debt, Trade Agreement Debt or Additional Future Debt owed to it.
Any party may rely on such information (or other means available to it) to
determine whether the Requisite Parties or the Special Requisite Parties, as the
case may be, have acted with respect to any action or proposed action.

            (c) Any Enforcement Notice, when issued, may be rescinded or
withdrawn with the consent of the Requisite Parties or Special Requisite
Parties, whichever shall have given such Enforcement Notice .

                  SECTION 4.6. TURNOVER OF COLLATERAL. If any Secured Party
acquires custody, control or possession of any payment constituting any
Collateral (including proceeds therefrom), other than pursuant to the terms of
Section 4.1(b), Section 4.1(c) or Section 4.2 hereof, such Secured Party shall
promptly cause such payment or Collateral to be delivered to or put in the
custody, possession or control of the Collateral Agent or, if the Collateral
Agent shall so designate, an agent of the Collateral Agent (which agent may be a
branch or affiliate of the Collateral Agent) in the same form of

<PAGE>
                                      -24-

payment received, with appropriate endorsements, for distribution in accordance
with the provisions of Section 4.1 or Section 4.2, as applicable. Until such
time as the provisions of the immediately preceding sentence have been complied
with, such Secured Party shall be deemed to hold such Collateral in trust for
the Collateral Agent. Notwithstanding the foregoing, neither BofA, any Note
Holder, Northern nor any holder of Additional Future Debt shall be required to
deliver to the Collateral Agent or such agent of the Collateral Agent, any
amounts received by BofA, such Note Holder, Northern or such holder of
Additional Future Debt prior to receipt by the Collateral Agent of a Notice of
Actionable Default to the extent that such amounts constitute (a) payments of
principal on BofA Debt, the Note Debt, the Trade Agreement Debt or Additional
Future Debt required to be made pursuant to the Loan Documents and due and paid
prior to such date, or (b) regular payments of interest, Make-Whole Amounts,
fees and other charges on or in respect of BofA Debt, the Note Debt, the Trade
Agreement Debt or Additional Future Debt due and paid prior to such date.

                  SECTION 4.7. PAYMENTS FROM ENFORCEMENT RIGHTS. Each of the
Secured Parties agrees with each other Secured Party that (a) if any Secured
Party exercises any right of setoff, banker's lien or similar right with respect
to any Collateral or any assets of the Company or any Guarantor, the amount set
off shall be applied pro rata to the Secured Obligations in accordance with
Section 4.1(b) or Section 4.2, as the case may be, and (b) if such Secured Party
shall receive from the Company or any Guarantor, whether by voluntary payment,
exercise of the right of setoff, counterclaim, cross-action, enforcement of the
claim in respect of the Secured Obligations owing to such Secured Party by
proceedings against the Company at law or in equity or by proof thereof in
bankruptcy, reorganization, liquidation, receivership or similar proceedings, or
otherwise, for application to the payment of the Secured Obligations owing to
such Secured Party any amount in excess of its ratable portion of the payments
received by the other Secured Parties with respect to BofA Debt, Note Debt,
Trade Agreement Debt and Additional Future Debt (as the case may be) held by all
of the Secured Parties as contemplated by Section 4.1(b) or Section 4.2, as the
case may be, such Secured Party will make such disposition and arrangements with
the other Secured Parties with respect to such excess, either by way of
distribution, pro tanto assignment of claims, subrogation or otherwise as shall
result in each Secured Party receiving in respect of the Secured Obligations
owing to it its proportionate payment as contemplated by Section 4.1(b) or
Section 4.2, as the case may be; provided that if all or any part of such excess
payment is thereafter recovered from such Secured Party, such disposition and
arrangements shall be rescinded and the amount restored to the extent of such
recovery, but without interest.

                  SECTION 4.8. WAIVERS AND AMENDMENTS OF CREDIT DOCUMENTS. Each
of the Note Holders, Northern, BofA and each holder of Additional Future Debt
agrees that, without the written consent of the Majority Secured Parties, it
shall not modify or amend any provisions of or give any waiver with respect to
the Credit Documents to which such party hereto is a signatory, if the effect of
such modification or amendment or waiver is (i) to increase the principal amount
of the Note Debt, Trade Agreement Debt, BofA Debt or Additional Future Debt then
outstanding (unless such increase in Note Debt, Trade Agreement Debt, BofA Debt
or Additional Future Debt constitutes Additional Future Debt, in which case no
such consent shall be required), or (ii) to amend or modify any term defined
therein which is incorporated by reference into this Agreement, or is
specifically referred to in this Agreement in such a way as to alter its meaning
in this Agreement, or (iii) to provide for loans to be made or letters of credit
to be issued (other

<PAGE>
                                      -25-

than by extension or renewal) after the issuance of an Enforcement Notice, or
(iv) to amend or modify any provision of any of the Security Documents or this
Agreement except as provided therein or herein. Except as otherwise specified in
the preceding sentence, the Note Holders, Northern, BofA and the holders of
Additional Future Debt, without the consent of the other parties, shall be free
to deal with the Company and the Guarantors in their respective sole discretion
under and in respect of the provisions of the Loan Documents to which they are
party, with the right and power without limitation to modify, amend or waive any
terms or provisions of such Loan Documents, to grant extensions of the time of
payment or performance, and to make compromises and settlements with the Company
or any Guarantor.

                  SECTION 4.9. INDEPENDENT INVESTIGATION; SHARING OF FINANCIAL
INFORMATION. Each of BofA, each Note Holder, Northern and each holder of
Additional Future Debt acknowledges and agrees that it has entered into the
Credit Documents to which it is party and (as applicable) extended funds and/or
credit or provided services to the Company on the basis of its own independent
investigation of the Company, its Subsidiaries and affiliated companies, and
their business, operations and financial condition, that it shall continue to
make such investigations in connection with the credit and/or loans extended to
the Company as it deems appropriate and that it has not conducted any such
investigations in reliance upon information, analysis and recommendations which
it may have obtained from any other Secured Party. Without derogation in any way
of the preceding sentence, the Company acknowledges and consents to any exchange
of information by and among BofA, each Note Holder, Northern and each holder of
Additional Future Debt, without regard to whether the impact of any such
exchange is favorable or unfavorable to the Company and without regard to the
accuracy or completeness of any information so exchanged.

                  SECTION 4.10. AGENTS. Except as specifically provided in this
Agreement, and except for the role of the Collateral Agent as specified in this
Agreement, BofA is not acting as agent for any other Secured Party, no Note
Holder is acting as agent for any other Secured Party and Northern is not acting
as agent for any other Secured Party; and nothing stated or implied in this
Agreement shall be deemed to create such an agency relationship.

      SECTION 5. CONCERNING THE COLLATERAL AGENT.

                  SECTION 5.1. APPOINTMENT OF COLLATERAL AGENT. The Note
Holders, BofA and Northern hereby appoint the Collateral Agent Bank to act as
collateral agent pursuant to the terms of this Agreement and the Security
Documents and hereby irrevocably authorize the Collateral Agent to execute and
enter into the A/R Intercreditor Agreement and an intercreditor agreement in
connection with any other Receivables Purchase Agreement on their behalf and to
take such action and perform such duties as provided therein, and the Collateral
Agent Bank hereby accepts such appointment. The relationship between the
Collateral Agent and the holders of the Secured Obligations is and shall be that
of agent and principal only, and nothing contained in this Agreement or any of
the Credit Documents shall be construed to appoint the Collateral Agent as a
trustee for any such holder.

<PAGE>
                                      -26-

                  SECTION 5.2. LIMITATIONS ON RESPONSIBILITY OF COLLATERAL
            AGENT.

            (a) The Collateral Agent shall not be responsible in any manner
whatsoever for the correctness of any recitals, statements, representations or
warranties contained herein or in any Security Document, except for those made
by it herein. The Collateral Agent makes no representation as to the value or
condition of the Collateral or any part thereof, as to the title of the Company
or any Guarantor to the Collateral, as to the security afforded by this
Agreement or any Security Document or, except as set forth in Section 6, as to
the validity, execution, enforceability, legality or sufficiency of this
Agreement or any Security Document, and the Collateral Agent shall incur no
liability or responsibility in respect of any such matters. The Collateral Agent
shall not be responsible for insuring the Collateral, for the payment of taxes,
charges, assessments or liens upon the Collateral or otherwise as to the
maintenance of the Collateral, except as provided in the immediately following
sentence when the Collateral Agent has possession of the Collateral. The
Collateral Agent shall have no duty to the Company or any Guarantor or to the
holders of any of the Secured Obligations as to the care of any Collateral in
its possession or control or in the possession or control of any agent or
nominee of the Collateral Agent or any income thereon or as to the preservation
of rights against prior parties or any other rights pertaining thereto, except
the duty to accord such of the Collateral as may be in its possession
substantially the same care as it accords its own assets and the duty to account
for monies received by it. The Collateral Agent's duties and responsibilities
shall be determined solely by the provisions of this Agreement and the Security
Documents to which it is a party, and the Collateral Agent shall not be liable
or responsible for any duties or obligations set forth in any other document to
which it is not a party.

            (b) The Collateral Agent shall not be responsible for any loss
suffered with respect to any investment permitted to be made under this
Agreement and shall not be responsible for the consequences of any oversight or
error of judgment whatsoever, except that the Collateral Agent may be liable for
losses due to its willful misconduct, gross negligence or breach of its
agreement set forth herein. The Collateral Agent shall not be required to
ascertain or inquire as to the performance by the Company of any of the
covenants or agreements contained herein or in any of the Credit Documents.
Neither the Collateral Agent nor any officer, agent or representative thereof
shall be personally liable for any action taken or omitted to be taken by any
such Person in connection with this Agreement or any Security Document except
for such Person's own gross negligence or willful misconduct. Neither the
Collateral Agent nor any officer shall be personally liable for any action taken
by any such Person in accordance with any notice given by the Requisite Parties
or Special Requisite Parties, as the case may be, in accordance with and
pursuant to the terms of this Agreement even if, at the time such action is
taken by any such Person, the Requisite Parties or Special Requisite Parties, as
the case may be, or Persons purporting to be the Requisite Parties or Special
Requisite Parties, as the case may be, are not so authorized by the Requisite
Parties or the Special Requisite Parties, as the case may be, to give such
notice, except where a Responsible Officer of the Collateral Agent has actual
knowledge that such Requisite Parties or Special Requisite Parties, as the case
may be, or Persons purporting to be the Requisite Parties or Special Requisite
Parties, as the case may be, are not so authorized by the Requisite Parties or
Special Requisite Parties, as the case may be, to give such notice. The
Collateral Agent may execute any of the powers granted under this Agreement or
any of the Security Documents or the A/R Intercreditor Agreement (or any other

<PAGE>
                                      -27-

intercreditor agreement executed by the Collateral Agent in accordance with the
terms of this Agreement) and perform any duty hereunder or thereunder either
directly or by or through agents, receivers, or attorneys-in-fact and shall not
be responsible for anything done by such agents, receivers or attorneys-in-fact
selected by it with due care.

            (c) Whenever pursuant to the provisions hereof or of any Security
Document it is required that any party hereto obtain the consent or approval of
the Collateral Agent, or that any matter prove satisfactory to the Collateral
Agent, or if the Collateral Agent, in its best judgment, needs clarification or
instruction concerning its duties or obligations hereunder, the Collateral
Agent, prior to giving any such consent or approval or indicating its
satisfaction with any such matter, or performing such duty or obligation, shall
(except where the failure to do so, in its good faith judgment, could imperil
the Collateral or the Liens thereon) be required to consult with the Secured
Parties in a manner deemed reasonable by the Collateral Agent, and the
Collateral Agent shall be protected in following any direction of the Requisite
Parties or Special Requisite Parties, as the case may be.

            (d) The foregoing provisions of this Section 5.2 shall not relieve
the Collateral Agent of any liability for any failure to perform any contractual
duty expressly undertaken by it to be performed under this Agreement if such
liability is caused by the gross negligence or willful misconduct of the
Collateral Agent.

                  SECTION 5.3. RELIANCE BY COLLATERAL AGENT; ETC.

            (a) Whenever in the performance of its duties under this Agreement
the Collateral Agent shall deem it necessary or desirable that a matter be
proved or established with respect to any Person in connection with the taking,
suffering or omitting of any action hereunder by the Collateral Agent, such
matter may be conclusively deemed to be proved or established by a certificate
executed by an officer of such Person, and the Collateral Agent shall have no
liability with respect to any action taken, suffered or omitted in reliance in
good faith thereon.

            (b) The Collateral Agent may consult with counsel and shall be fully
protected in taking any action hereunder in good faith in accordance with any
advice of such counsel. The Collateral Agent shall have the right but not the
obligation at any time to seek instructions concerning the administration of
this Agreement, the duties created hereunder, or any of the Collateral from any
court of competent jurisdiction.

            (c) The Collateral Agent shall be fully protected in relying in good
faith upon any resolution, statement, certificate, instrument, opinion, report,
notice, request, consent, order or other paper or document which it believes to
be genuine and to have been signed or presented by the proper party or parties.
In the absence of its gross negligence or willful misconduct, the Collateral
Agent may conclusively rely in good faith, as to the truth of the statements and
the correctness of the opinions expressed therein, upon any certificate or
opinions furnished to the Collateral Agent in connection with this Agreement.

            (d) The Collateral Agent shall not be deemed to have actual,
constructive, direct or indirect notice or knowledge of the occurrence of any
Event of Default or Actionable

<PAGE>
                                      -28-

Default unless and until a Responsible Officer of the Collateral Agent shall
have received a Notice of Actionable Default or notice of such Event of Default.
The Collateral Agent shall have no obligation whatsoever either prior to or
after receiving such a Notice of Actionable Default to inquire whether an
Actionable Default has, in fact, occurred and shall be entitled to rely in good
faith conclusively, and shall be fully protected in so relying, on any
certificate so furnished to it and shall have no obligation, absent written
instructions from the Requisite Parties or Special Requisite Parties, as the
case may be, to take or omit to take any action with respect to such Notice of
Actionable Default.

            (e) To the extent the Collateral Agent is required (pursuant to
Section 4, Section 11, Section 12, Section 13, or otherwise) to determine any
amount, or take any action to distribute any amount, of any Secured Obligation
or other payments hereunder, it shall have no obligation to do so unless such
amount shall have been certified in writing by the Requisite Parties or the
Special Requisite Parties, as the case may be, as being the amount in question.
Each of the other parties hereto agrees to certify such amounts upon request of
the Collateral Agent. If any dispute or disagreement shall arise as to the
allocation of any sum of money received by the Collateral Agent hereunder or
under any Security Document, the Collateral Agent shall have the right to
deliver such sum to a court of competent jurisdiction and therein commence an
action for interpleader.

                  SECTION 5.4. RESIGNATION OR REMOVAL OF THE COLLATERAL AGENT.
The Collateral Agent may at any time resign by giving sixty (60) days prior
written notice thereof to each Secured Party and the Company, and the Collateral
Agent may at any time be removed for cause (consisting of fraud, gross
misconduct, willful or reckless breach of this Agreement or other just cause, as
determined in their discretion by the Majority Secured Parties) by sixty (60)
days prior written notice thereof to the Collateral Agent, each other Secured
Party and the Company given by the Majority Secured Parties, provided that in
the case of fraud, gross misconduct or willful or reckless breach of this
Agreement such removal may be effective immediately upon five (5) days after
giving of such notice to the Collateral Agent and provided further that no
resignation or removal shall be effective until a successor for the Collateral
Agent is appointed. Upon such resignation or removal, the Majority Secured
Parties shall have the right to appoint a successor Collateral Agent. If no
successor Collateral Agent shall have been so appointed by the Majority Secured
Parties and shall have accepted such appointment within forty-five (45) days
after the retiring Collateral Agent's giving of notice of resignation or the
giving of notice of removal, as the case may be, then the retiring Collateral
Agent may, on behalf of the Secured Parties, appoint a successor Collateral
Agent, which shall be a financial institution having a long-term bank deposit
rating of not less than "A" from Standard & Poor's Ratings Group, a Division of
McGraw-Hill, Inc., or "A-2" from Moody's Investors Services, Inc. Upon the
acceptance of any appointment as Collateral Agent hereunder by a successor
Collateral Agent, such successor Collateral Agent shall thereupon succeed to and
become vested with all the rights, powers, privileges and duties of the retiring
Collateral Agent, and the retiring Collateral Agent shall be discharged from its
duties and obligations hereunder. After any retiring Collateral Agent's
resignation or removal, the provisions of this Agreement and the Security
Documents shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as Collateral Agent. Any
corporation into which the Collateral Agent Bank may be merged or with which it
may be consolidated, or any corporation which acquires all or

<PAGE>
                                      -29-

substantially all of the corporate trust business of the Collateral Agent Bank,
including the collateral agency established pursuant to this Agreement, or any
corporation resulting from any merger or consolidation to which the Collateral
Agent Bank shall be a party, shall be the successor to the Collateral Agent Bank
without the execution of any paper.

                  SECTION 5.5. EXPENSES AND INDEMNIFICATION.

            (a) By countersigning this Agreement, the Company agrees (i) to
reimburse the Collateral Agent, promptly, for any reasonable expenses incurred
by the Collateral Agent, including reasonable counsel fees and disbursements and
compensation of agents, arising out of, in any way connected with, or as a
result of, the execution or delivery of this Agreement or any Security Document
or any agreement or instrument contemplated hereby or thereby or the performance
by the parties hereto or thereto of their respective obligations hereunder or
thereunder or in connection with the enforcement or protection of the rights of
the Collateral Agent and the Secured Parties hereunder or under the Security
Documents, and (ii) to indemnify and hold harmless the Collateral Agent and its
directors, officers, employees and agents, promptly, from and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, and reasonable costs, expenses or disbursements of any kind or nature
whatsoever ("LOSSES") which may be imposed on, incurred by or asserted against
the Collateral Agent Bank in its capacity as the Collateral Agent or any of them
in any way relating to or arising out of this Agreement or any Security Document
or any action taken or omitted by them under this Agreement or any Security
Document; provided that the Company shall not be liable to the Collateral Agent
for any portion of such Losses resulting from the gross negligence or willful
misconduct of the Collateral Agent or any of its directors, officers, employees
or agents as determined by a final non-appealable order of a court of competent
jurisdiction. A statement by the Collateral Agent that is submitted to the
Company with respect to the amount of such expenses and containing a basic
description thereof and/or the amount of its indemnification obligation shall be
prima facie evidence of the amount thereof owing to the Collateral Agent or the
Collateral Agent Bank, as the case may be; provided, however, that the Company
shall nonetheless have the right to dispute any such amount and, to the extent
provided in this Section 5.5, the reasonableness thereof. Except as otherwise
expressly provided herein, the Collateral Agent shall be under no obligation to
take any action to protect, preserve or enforce any rights or interests in the
Collateral or to take any action in connection with the execution or enforcement
of its duties hereunder, whether on its own motion or on request of any other
Person, which in the opinion of the Collateral Agent may involve loss, liability
or expense to it, unless one or more of the Secured Parties shall offer and
furnish security or indemnity, reasonably satisfactory to the Collateral Agent
in accordance herewith, against loss, liability and expense to the Collateral
Agent. Notwithstanding anything to the contrary contained in this Agreement, or
any Security Document or any other documents noted in Section 10 of this
Agreement, in the event that the Collateral Agent is entitled or required to
commence an action to foreclose on such Security Document or other document, or
otherwise exercise its remedies to acquire control or possession of any property
constituting all or part of the Collateral, the Collateral Agent shall not be
required to commence any such action or exercise any such remedy if the
Collateral Agent has determined in good faith that it may incur liability under
any federal or state environmental or hazardous waste law, rule or regulation as
the result of the presence at, or release on or from, any property of any
hazardous materials or waste, as defined under such federal or state laws,
unless it has

<PAGE>
                                      -30-

received security or indemnity from a Person, in an amount and in form, all
satisfactory to the Collateral Agent in its sole discretion, protecting the
Collateral Agent from all such liability.

            (b) The indemnification provisions in this Section 5.5(b) and
Section 5.5(c) are in addition to the indemnification provisions in Section
5.5(a). Without limiting any indemnification the Company or any Obligor has
granted in any other provision of this Agreement or in any other Credit
Document, the Company and each Obligor hereby indemnifies and holds harmless the
Collateral Agent and each of the Secured Parties and their respective directors,
officers, employees and agents (collectively, the "INDEMNIFIED PARTIES") from
and against any and all Losses which may be imposed on, incurred by or asserted
against the Indemnified Parties or any of them as a result of, arising out of,
or relating to any claim, action or proceeding by any third party (other than
any Indemnified Party) with respect to (i) any accident, injury to or death of
persons or loss of or damage to or loss of the use of property occurring on or
about any Mortgaged Property or any part thereof or the adjoining sidewalks,
curbs, vaults and vault spaces, if any, streets, alleys or ways, (ii) any use,
non-use or condition of any Mortgaged Property or any part thereof or the
adjoining sidewalks, curbs, vaults and vault spaces, if any, streets, alleys or
ways, (iii) any failure on the part of the Company or any applicable Obligor to
perform or comply with any of the terms of any Mortgage, (iv) performance of any
labor or services or the furnishing of any materials or other property in
respect of any Mortgaged Property or any part thereof made or suffered to be
made by or on behalf of the Company or any applicable Obligor, (v) any
negligence or tortious act on the part of the Company or any applicable
Mortgagor or any of its agents, contractors, lessees, licensees or invitees, or
(vi) any work in connection with any alterations, changes, new construction or
demolition of or additions to any Mortgaged Property (collectively, the
"INDEMNIFIED LIABILITIES"); provided, however, that the Company or any Obligor
shall not indemnify or hold harmless any Indemnified Party against any
Indemnified Liabilities arising (x) by reason of any Indemnified Party's gross
negligence or willful misconduct, or (y) in the case of clauses (i), (ii), (iv)
and (vi) above, after termination of the Company's or such Obligor's ownership
or operation of any Mortgaged Property.

            (c) In the event that (i) any Indemnified Party is made a party to
any action or proceeding by reason of the execution of this Agreement or any
Security Document or (ii) any action or proceeding shall be commenced in which
it becomes necessary to defend or uphold the lien of any Mortgage, all
reasonable sums paid by the Indemnified Parties for the expense of any
litigation to prosecute or defend the rights and lien created by any Mortgage or
otherwise shall be paid by the Company or any applicable Mortgagor to such
Indemnified Parties, as hereinafter provided. The Company or any applicable
Mortgagor will pay and save the Indemnified Parties harmless against any and all
liability with respect to any intangible personal property tax or similar
imposition of any jurisdiction or any subdivision or authority thereof now or
hereafter in effect, to the extent that the same may be payable by the
Indemnified Parties in respect of any Mortgage or any obligation secured
thereby. In case any action, suit or proceeding is brought against any
Indemnified Party by reason of any such occurrence, the Company or any
applicable Mortgagor, upon written request of such Indemnified Party, will, at
the Company's or such Mortgagor's expense, resist and defend such action, suit
or proceeding or cause the same to be resisted or defended by counsel designated
by the Company or such Mortgagor and approved by such Indemnified Party, which
approval shall not be unreasonably withheld or delayed. The obligations of the
Company and each Mortgagor under this Section 5.5 shall survive any discharge or

<PAGE>
                                      -31-

reconveyance of any Mortgage and the payment in full of the obligations secured
thereby. If and to the extent that the foregoing undertaking is unenforceable
for any reason, the Company and each Mortgagor hereby agrees to make the maximum
contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law. (d) All amounts payable
to the Indemnified Parties under this Section 5.5 shall be deemed indebtedness
secured by the Security Documents and shall bear interest at the highest
interest rate for overdue payments provided for in any of the Credit Documents
commencing 30 days after any Obligor's receipt of written notice that such
amounts are due and owing.

                  SECTION 5.6. EXPENSES AND INDEMNIFICATION BY SECURED PARTIES.
Each of BofA, each Note Holder, Northern and each holder of Additional Future
Debt severally agrees (i) to reimburse the Collateral Agent, promptly, in the
amount of its pro rata share for any expenses referred to in Section 5.5 and
reasonable fees due pursuant to Section 5.7 which shall not have been reimbursed
or paid by the Company or paid from the proceeds of Collateral as provided
herein and (ii) to indemnify and hold harmless the Collateral Agent, the
Collateral Agent Bank and its directors, officers, employees and agents,
promptly, in the amount of its pro rata share, from and against any and all
Losses referred to in Section 5.5, to the extent the same shall not have been
reimbursed by the Company or paid from the proceeds of Collateral as provided
herein; provided that none of BofA, any Note Holder, Northern or any holder of
Additional Future Debt shall be liable to the Collateral Agent or the Collateral
Agent Bank for any portion of such Losses resulting from the gross negligence or
willful misconduct of, or the gross negligence or willful misconduct in the
failure to perform any express duty undertaken under this Agreement to be
performed by, the Collateral Agent or the Collateral Agent Bank or any of its
directors, officers, employees or agents. For purposes of this Section 5.6, the
pro rata share of any Secured Party's claim for which a reimbursement or
indemnity obligation arises under this Section 5.6 shall be its percentage share
of the sum of the Secured Obligations, as of the last day of the calendar month
preceding the date on which such claim was incurred and on which any Principal
Obligations were outstanding.

                  SECTION 5.7. COLLATERAL AGENT'S FEE. By countersigning this
Agreement, the Company agrees to pay to the Collateral Agent for the Collateral
Agent's own account, a non-refundable Collateral Agent's fee, on the date hereof
and an additional yearly fee. Such yearly fees shall be payable as specified in
a separate letter agreement between the Company and the Collateral Agent Bank
until the Secured Obligations have been paid in full in cash, the commitments
represented by the Credit Documents shall have expired or been reduced to zero
or terminated, there is no Undrawn LC/Guaranty Exposure, and the Collateral
Agent no longer has any duties hereunder.

            SECTION 6. REPRESENTATIONS AND WARRANTIES. Each of the Collateral
Agent, BofA, each Note Holder, Northern, each holder of Additional Debt and, by
countersigning this Agreement, the Company and each Guarantor, represents and
warrants to the other parties hereto that (a) the execution, delivery and
performance of this Agreement or the Joinder Agreement to which it is a party
(in the case of a holder of Additional Future Debt) (i) have been duly
authorized by all requisite corporate or other action on its part and (ii) do
not conflict with or result in any breach or contravention of any provision of
law, statute, rule or

<PAGE>
                                      -32-

regulation to which it is subject or any judgment, order, writ, injunction,
license or permit applicable to it and will not conflict with any provision of
its charter documents or bylaws or any agreement or other instrument binding
upon it; and (b) this Agreement or such Joinder Agreement, as the case may be,
has been duly executed and delivered by it and constitutes its legal, valid and
binding obligation, enforceable in accordance with its terms.

      SECTION 7. AMENDMENT OF THIS AGREEMENT.

                  SECTION 7.1. Amendments. No modification or amendment of this
Agreement shall be effective unless the same shall be in writing and signed by
the Majority Secured Parties and no modification or amendment of any Security
Document shall be effective, nor shall any waiver of any provision of any
Security Document be executed by the Collateral Agent, without the written
consent of the Majority Secured Parties; provided, however, (i) no amendment or
waiver shall adversely affect any of the Collateral Agent's rights, immunities
or rights to indemnification hereunder or under any of the Security Documents or
expand its duties or reduce any amount payable to the Collateral Agent hereunder
or under any Security Documents without the written consent of the Collateral
Agent; (ii) Sections 3 and 5 of this Agreement and any other provision of this
Agreement or of any of the Security Documents affecting the rights and
obligations of the Collateral Agent hereunder may not be amended without the
written consent of the Collateral Agent; (iii) no modification or amendment of
Section 2.2 or the defined terms used therein, Section 4.9, Section 5.4, Section
5.5, Section 5.7, Section 6, this Section 7.1(iii), Section 8, Section 10,
Section 11, Section 12 or Section 13 of this Agreement shall be effective unless
the same shall have been consented to by the Company; (iv) no modification,
amendment or waiver that changes the amount that a Secured Party receives from a
distribution hereunder or that delays the time of a distribution hereunder shall
be effective without the consent of such Secured Party and (v) none of the
Material Provisions of any of the Security Documents may be created, amended or
waived without the consent of all holders of Secured Obligations. Any Security
Document executed after the date hereof shall be approved by the Majority
Secured Parties as to form.

                  SECTION 7.2. WAIVERS. Except as provided in Section 7.1, no
waiver of any provision of this Agreement and no consent to any departure by any
party hereto from the provisions hereof shall be effective unless such waiver or
consent shall be set forth in a written instrument executed by the party against
which it is sought to be enforced, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No
notice to or demand on any party hereto in any case shall entitle such party to
any other or further notice or demand in the same, similar or other
circumstances.

      SECTION 8. APPROVAL BY THE COMPANY AND GUARANTORS; COMPANY'S OBLIGATIONS
ABSOLUTE.

            SECTION 8.1. GENERAL. By countersigning this Agreement, each of the
Company and the Guarantors acknowledges and consents to and agrees to perform
and be bound by each provision of this Agreement which expressly recites that

<PAGE>

                                      -33-

               SECTION 8.2. OBLIGATIONS ABSOLUTE. Nothing contained in this
Agreement shall impair, as between the Company, or any Guarantor and each of
BofA, each Note Holder, Northern and each holder of Additional Future Debt, (a)
the obligation of the Company or such Guarantor to pay to the Note Holders all
amounts payable in respect of the Note Debt as and when the same shall become
due and payable in accordance with the terms thereof, or prevent any of the Note
Holders (except as expressly otherwise provided in this Agreement) from
exercising all rights, powers and remedies otherwise permitted by the Note
Documents and by applicable law upon a default in the payment or performance of
the Note Debt, all, however, subject to the rights of BofA, Northern and the
holders of Additional Future Debt as set forth in this Agreement, or (b) the
obligation of the Company or such Guarantor to pay to BofA all amounts payable
in respect of BofA Debt as and when the same shall become due and payable in
accordance with the terms thereof, or prevent BofA (except as expressly
otherwise provided in this Agreement) from exercising all rights, powers and
remedies otherwise permitted by the Reimbursement Agreements, the IRB Bond
Guaranties and by applicable law upon a default in the payment or performance of
BofA Debt, all, however, subject to the rights of the Note Holders, Northern and
the holders of Additional Future Debt as set forth in this Agreement, (c) the
obligation of the Company or such Guarantor to pay to Northern all amounts
payable in respect of the Trade Agreement Debt as and when the same shall become
due and payable in accordance with the terms thereof, or prevent Northern
(except as expressly otherwise provided in this Agreement) from exercising all
rights, powers and remedies otherwise permitted by the Trade Agreement and by
applicable law upon a default in the payment or performance of the Trade
Agreement Debt, all, however, subject to the rights of the Note Holders, BofA
Issuer and the holders of Additional Future Debt as set forth in this Agreement
and (d) the obligation of the Company or such Guarantor to pay to any holder of
Additional Future Debt all amounts payable in respect of such Additional Future
Debt as and when the same shall become due and payable in accordance with the
terms thereof, or prevent any holder of Additional Future Debt (except as
expressly otherwise provided in this Agreement) from exercising all rights,
powers and remedies otherwise permitted by such Additional Future Debt Documents
and by applicable law upon a default in the payment or performance of such
Additional Future Debt, all, however, subject to the rights of the Note Holders,
Northern and BofA as set forth in this Agreement.

               SECTION 8.3. NO ADDITIONAL RIGHTS FOR COMPANY HEREUNDER. If the
Collateral Agent or any Secured Party shall enforce its rights or remedies in
violation of the terms of this Agreement, the Company and each Guarantor agrees,
by its consent hereto, that it shall not use such violation as a defense to such
enforcement by any such party nor assert such violation as a counterclaim or
basis for setoff or recoupment against any such party (except to the extent such
violation affects the rights of the Company or any Guarantor set forth in this
Agreement). Nothing contained in this Agreement shall constitute a commitment by
BofA, any Note Holder, Northern or any holder of Additional Future Debt to make
available to the Company or any Guarantor any advances, loans or letters of
credit beyond such advances, loans or letters of credit as specifically provided
for in the Loan Documents.

               SECTION 9. COLLATERAL AGENT AS AGENT AND LENDER. If a Secured
Party is at any time the Collateral Agent, such Secured Party shall, in its
individual capacity and as Collateral Agent, have the same obligations and the
same rights, powers and privileges as it would have had were it not also the
Collateral Agent.

            SECTION 10. COVENANTS CONCERNING COLLATERAL

               SECTION 10.1. ADDITIONAL ASSIGNMENTS, AND MORTGAGES.

            (a) Without limiting the obligations of the Company or any of its
Subsidiaries in the Credit Documents (and subject to the provisions of the
Credit Documents and this Agreement), the Company shall, and shall cause each of
its Significant Subsidiaries which has not theretofore executed and delivered
one or more Security Documents in favor of the Collateral Agent with respect to
all of its assets (other than Excluded Collateral) as security for the Secured
Obligations, to execute and deliver to the Collateral Agent such Security
Documents, and take such other action, as may be requested to grant Liens to the
Collateral Agent on all its assets (other than Excluded Collateral).

            (b) Without limiting the obligations of the Company or any of its
Subsidiaries in the Credit Documents (and subject to the provisions of the
Credit Documents and this Agreement) if the Company or any of its Significant
Subsidiaries acquires after the date hereof ownership of a Significant Real
Estate Interest, the Company shall, and shall cause such Significant Subsidiary,
to deliver within a reasonable time period to the Collateral Agent a fully
executed mortgage or deed of trust over such interest in real estate, together
with any environmental site assessments in the possession of the Company or such
Significant Subsidiary and evidence of insurance with the Collateral Agent named
as loss payee and additional insured with respect to such real estate as the
Collateral Agent (upon instruction from the Requisite Parties) may reasonably
request in accordance with good banking and lending practices, all in form and
content acceptable to the Requisite Parties. If such Significant Subsidiary is
not a Guarantor, the Company shall cause such Significant Subsidiary to become a
Guarantor and a party to this Agreement. If the Company or the Significant
Subsidiary acquiring such Significant Real Estate Interest obtains a current
owner's title insurance policy in respect of all or a portion of such
Significant Real Estate Interest in connection with the acquisition of such
Significant Real Estate Interest, the Company shall also deliver to the
Collateral Agent a customary lender's title insurance policy in respect of such
Significant Real Estate Interest for the benefit of the Collateral Agent from
the insurance company issuing such owner's title insurance policy in an insured
amount equal to the insured amount of such owner's title insurance policy. The
Company further agrees that, following the taking of such actions, the
Collateral Agent shall have for the pari passu benefit of the Secured Parties a
valid and enforceable Lien over such interest in real estate, free and clear of
all Liens, defects and encumbrances other than such Liens, defects or
encumbrances existing on such Significant Real Estate Interest at the time such
Significant Real Estate Interest shall have been so acquired.

               SECTION 10.2. PERFECTION CERTIFICATE. The Company shall furnish
to the Collateral Agent and to each of the holders of Secured Obligations not
later than October 15 of each year beginning with the year 2004, a fully
completed Perfection Certificate substantially in the form attached hereto as
Exhibit C setting forth the information required thereby as of October 1st in
such year. Upon receipt of such Perfection Certificate the Collateral Agent
shall forward a copy of such Perfection Certificate to special counsel to the
Requisite Parties if such special counsel is known to the Collateral Agent. If
such special counsel is not known to the Collateral Agent, it shall request that
the holders of the Secured Obligations notify the Collateral Agent of the name

<PAGE>

                                      -35-

and address of such special counsel. Upon the effective date of this Agreement
such special counsel is Bingham McCutchen, LLP of Hartford, Connecticut. Upon
request of the Requisite Parties or such special counsel the Company will take
any and all actions, and execute and deliver such documents and instruments,
with respect to the recording, filing, registering, re-recording, refiling and
re-registering of any of the Security Documents in respect of any Collateral as
are necessary under the law of the jurisdiction in which the Collateral is
located or under other applicable law to maintain the continued perfection,
existence and priority of the Lien of the Security Documents (including, without
limitation, to the extent provided for therein and herein on any property
acquired by the Company or any Guarantor after the date hereof), and to fully
preserve and protect the rights, and under the Security Documents of or for the
benefit of the Collateral Agent in respect of such Liens and the Collateral.

            SECTION 11. CONDEMNATION

               SECTION 11.1. TAKINGS. Each Obligor, in each Mortgage to which
such entity is a party, shall irrevocably assign, or cause to be assigned, to
the Collateral Agent a security interest in and Lien on any award or payment
which may become payable to such entity by reason of any taking of a Significant
Real Estate Interest encumbered by such Mortgage or any part thereof, whether
directly or indirectly, temporarily or permanently, in or by condemnation or
other eminent domain proceedings (a "Taking"). All rights of the Collateral
Agent under this Section 11 as to any Significant Real Estate Interest are
subject to any rights in favor of holders of Permitted First Priority Liens in
such Significant Real Estate Interest and shall be enforceable to the fullest
extent not prohibited or restricted by the terms of any agreements or
instruments creating such Permitted First Priority Liens.

               SECTION 11.2. APPLICATION OF AWARDS.

            (a) Any awards or payments made with respect to any Taking relating
to a Significant Real Estate Interest shall be paid or distributed as provided
in this Section. If any Obligor shall receive directly any such award or
payment, promptly following the receipt thereof such Obligor shall transfer in
immediately available funds the Net Proceeds in respect of such Taking from such
award or payment to the Collateral Agent and the Collateral Agent shall
distribute such Net Proceeds in accordance with the provisions of this clause
(a). If the Collateral Agent shall receive directly any such award or payment
and no Default or Event of Default then exists, the Collateral Agent shall,
prior to making any other payment or distribution hereunder, transfer to the
Obligor whose Property was the subject of such Taking an amount in immediately
available funds equal to the difference between (A) the amount of such award or
payment so received and (B) the Net Proceeds relating thereto (as set forth in a
certificate executed by a Senior Officer and delivered to the Collateral Agent),
and thereafter the remainder of such award or payment shall be distributed as
provided below. Any and all amounts to be distributed as provided in this clause
(a) shall be distributed as follows:

                  (i) if the gross amount of any awards or payments with respect
      to such Taking are in an amount less than $5,000,000, the Net Proceeds
      thereof held by the Collateral Agent shall be immediately payable in
      immediately available funds directly to such Obligor which is the subject
      of such Taking upon receipt of a certificate executed by

<PAGE>

                                      -36-

      a Senior Officer which states that no Default or Event of Default exists
      and such Obligor will use such Net Proceeds to repair or replace the
      Significant Real Estate Interest which was the subject of such Taking; and

                  (ii) if the gross amount of any awards or payments with
      respect to such Taking equals or exceeds $5,000,000, the Secured Parties
      shall review with the Company, the Company's business proposal with
      respect to the application of the Net Proceeds thereof held by the
      Collateral Agent, which proposal the Company shall submit to the Secured
      Parties at any time but no later than thirty (30) Business Days after the
      date such award has been paid, and give due consideration to the merits
      and rationale of such proposal recognizing the integrated nature of the
      Company's manufacturing facilities and operations. Within twenty (20)
      Business Days of receipt of the Company's proposal, the Requisite Parties
      shall, following review thereof, determine (which determination shall be
      reasonably made and not unduly delayed) whether such Net Proceeds shall be
      applied as provided in such proposal. If the Company shall not have
      received a reply from the Requisite Parties by the end of such twenty (20)
      Business Day period, the Company shall deliver a written notice to each of
      the Secured Parties requesting a determination as to such proposal and
      shall give the Requisite Parties an additional five (5) Business Days
      after the delivery of such second notice to deliver a written acceptance
      or rejection of such proposal. If the Requisite Parties fail to advise the
      Company in writing of their determination with respect to such proposal as
      provided herein prior to the end of such five (5) Business Day period,
      they shall be deemed to have accepted such proposal. Upon actual or deemed
      acceptance of such proposal, the Collateral Agent shall promptly transfer
      in immediately available funds such Net Proceeds to the relevant Obligor
      and the relevant Obligor shall act diligently and good faith to apply such
      Net Proceeds substantially as provided in such proposal. If such proposal
      is not accepted, then the Net Proceeds shall be applied as an Offered
      Repayment as set forth in Section 11.4 below.

            (b) Notwithstanding anything contained herein, if any Default or
Event of Default shall have occurred and be continuing, any Net Proceeds of a
Taking, together with any other amounts held by the Collateral Agent in respect
of such Taking, shall be applied as an Offered Repayment as set forth in Section
11.4 below unless the Majority Secured Parties and the Company agree otherwise.
The Collateral Agent shall promptly and, in any case, not more than five (5)
Business Days after the receipt of any funds hereunder satisfactorily identified
to the Collateral Agent as Net Proceeds of a Taking, inform the Obligors and the
Secured Parties in writing of such receipt and the amount thereof.

               SECTION 11.3. SETTLEMENT OF CONDEMNATION CLAIMS. Immediately upon
receipt by any of the Obligors of notice of the institution of any proceeding or
negotiations for a Taking, the Obligors shall give notice thereof to the
Collateral Agent. The Collateral Agent may, but shall be under no obligation to,
appear in any such proceedings and participate in any such negotiations and may
be represented by counsel. The Obligors, notwithstanding that the Collateral
Agent may not be a party to any such proceeding, will promptly give, or cause to
be given, to the Collateral Agent copies of all notices, pleadings, judgments,
determinations and other papers received by any Obligor. The Obligors will not
enter into, or permit to be entered into, any agreement permitting or consenting
to the Taking of the applicable Significant Real Estate Interest, or any

<PAGE>

                                      -37-

part thereof, or providing for the conveyance thereof in lieu of condemnation,
with anyone authorized to acquire the same in condemnation or by eminent domain
which, for any award or payment, is estimated by the Collateral Agent in good
faith to exceed $5,000,000, unless the Collateral Agent, acting at the direction
of the Requisite Parties, shall first have consented thereto in writing. The
Requisite Parties agree to consider granting such consent without undue delay.
If a Default or Event of Default has occurred and is continuing, the Collateral
Agent, acting at the direction of the Requisite Parties, shall be authorized,
but shall not be obligated, to negotiate, adjust, compromise or settle any
Taking award and appear in any proceeding arising in connection with such
Taking. In connection therewith, the Obligors do hereby irrevocably authorize,
empower and appoint the Collateral Agent as attorney-in-fact for the Obligors
(which appointment is coupled with an interest) to do any and all of the
foregoing in the name and on behalf of the Obligors. The Requisite Parties agree
to act in good faith without undue delay in issuing any such written instruction
and approving any such adjustment.

               SECTION 11.4. OFFERED REPAYMENT. Any Net Proceeds to be applied
as an Offered Repayment as provided in Section 11.2(a)(ii) or Section 11.2(b)
shall be offered pro rata to all Secured Parties as a prepayment as provided in
Section 11.5 below. Each such Offered Repayment shall be made in writing as soon
as practicable after the Obligors being informed, in writing, by the Collateral
Agent of their obligation to make such Offered Repayment but, in any case, not
later than ten (10) days thereafter. Each Offered Repayment shall specify the
date on which the prepayment provided therein is to be made (which shall be a
Business Day and shall not be a date more than twenty-five (25) days after the
date of the delivery of such Offered Repayment), the principal amount of the
Secured Obligations of each recipient of such Offered Repayment then being
offered to be prepaid and the amount of accrued interest to be paid thereon. To
accept or reject any Offered Repayment under this Section 11.4, in whole or in
part, any Secured Party shall cause a written notice of such acceptance or
rejection to be delivered to the Obligors not later than fifteen (15) days after
the date of receipt by such holder of such Offered Repayment (it being
understood that the failure by a holder to accept in full or in part such
Offered Repayment as provided herein prior to the end of such fifteen (15) day
period shall be deemed to constitute a rejection of said Offered Repayment, or,
if so indicated as to any Secured Party on the Schedule 14.4 or in a written
notice delivered to the Company by any Secured Party within 60 days of the date
hereof, an acceptance of such Offered Repayment). The Obligors shall inform the
Collateral Agent, in writing not less than five (5) Business Days prior to any
date fixed for effecting of the payments contemplated by any accepted Offered
Repayment under this Section 11.4, of all amounts due in respect of each of such
accepted Offered Repayments, the payment date therefor, the recipients thereof,
and the payment address and payment method required in respect of each such
recipient. Upon the receipt by the Collateral Agent of written instructions from
the Obligors (or the Requisite Parties, in the event that the Obligors fail to
give such notice within a reasonable time) directing the Collateral Agent to
effect the payment in immediately available funds of accepted Offered Repayments
from the Net Proceeds then held by the Collateral Agent, as expressly provided
in the immediately preceding sentence, the Collateral Agent shall effect the
payment of such accepted Offered Repayments as so instructed. To the extent that
any such Net Proceeds shall not have been utilized to pay or prepay Secured
Obligations as a result of one or more holders of Secured Obligations rejecting
(in whole or in part) or being deemed to have rejected their respective Offered
Repayments, upon receipt of a written demand from the Obligors (or the

<PAGE>

                                      -38-

Requisite Parties, in the event that the Obligors fail to give such notice
within a reasonable time), the Collateral Agent shall pay such remaining Net
Proceeds, together with any interest accrued thereon, promptly to the Obligors.
Only upon the Collateral Agent effecting the payment in full of all of the
amounts owing in respect of the applicable accepted Offered Repayments under
this Section 11.4 will the Obligors be deemed to have discharged the payment
obligations they have under this Section 11.4 with respect to such accepted
Offered Repayments. The Obligors agree that they will instruct the Collateral
Agent to effect the payment of all related Offered Repayments to all applicable
Secured Parties simultaneously. Notwithstanding the foregoing, if, to the extent
required by the operation of any provision of any of the Credit Documents (it
being understood that the Loan Documents outstanding on the date hereof contain
no such provision), the Obligors are prohibited from making any Offered
Repayment such Offered Repayment shall be deemed to have been rejected by each
Secured Party who is a party to the Credit Document containing such prohibition.

               SECTION 11.5. APPLICABLE PREPAYMENT PROVISIONS. Each accepted
Offered Repayment pursuant to Section 11.4 shall be made in accordance with, and
subject to, (a) Section 2.2(a) of each of the Note Documents (with respect to
any prepayment of the Note Principal Obligations) but without payment of any
Make-Whole Amount, (b) Section 3.6 and Section 3.4(iii)(d) of the Trade
Agreement (with respect to any prepayment of the Trade Agreement Debt) but
without payment of any prepayment or breakage fees, and (c) any one or more
similar provisions in a similar section in the Additional Future Debt Documents
(with respect to any prepayment of the Additional Future Debt), in each case, as
certified to the Collateral Agent by the Secured Party entitled to receive such
Offered Repayment. Each accepted Offered Repayment in respect of any BofA Debt
shall be deposited in the Special Cash Collateral Account as a Proceeds Deposit.
To the extent any such sections of the Loan Documents referred to in this
Section 11.5 contain notice and procedural provisions, such provisions are
hereby deemed waived to permit prepayments under this Section 11.5.

               SECTION 11.6. WAIVER OF OFFERED REPAYMENT. The Majority Secured
Parties may at any time within twenty (20) days after receipt of written
notification from the Collateral Agent of its receipt of any funds arising from
a Taking, as provided for in Section 11.2(b) above, waive the obligation of the
Obligors to make Offered Repayments in respect of such award, as provided in
Section 11.2 above, by delivering a written notice of waiver in respect thereof
to the Obligors and the Collateral Agent. In such event, the Collateral Agent
shall promptly thereafter transfer in immediately available funds all such funds
held by it to the Obligor whose Property was the subject of such Taking.

               SECTION 11.7. COLLATERAL AGENT EXPENSES. The Obligors shall
promptly reimburse the Collateral Agent upon demand for all of the Collateral
Agent's reasonable out-of-pocket expenses (including reasonable attorney's fees)
incurred in performing its duties under this Section 11. To the extent the
Collateral Agent has not been so reimbursed by the Obligors (or arrangements
therefor made to the satisfaction of the Collateral Agent), any disbursement to
be made by the Collateral Agent pursuant to this Section 11 shall be net of all
of the Collateral Agent's reasonable out-of-pocket expenses (including
reasonable attorney's fees) incurred in performing its duties under this
Section 11.

            SECTION 12. APPLICATION OF INSURANCE PROCEEDS

               SECTION 12.1. GENERAL.

            (a) Any insurance proceeds (other than Excluded Insurance Proceeds)
which are paid in respect of the damage, destruction, loss or other casualty
(each, a "CASUALTY") of the Collateral under any insurance policy required to be
maintained by any one or more of the Obligors under the provisions of any Credit
Document shall be paid or distributed as provided in this Section. If any
Obligor shall receive directly any such insurance proceeds, promptly following
the receipt thereof such Obligor shall transfer in immediately available funds
the Net Proceeds in respect of such Casualty from such insurance proceeds to the
Collateral Agent and the Collateral Agent shall distribute such Net Proceeds in
accordance with the provisions of this clause (a). If the Collateral Agent shall
receive directly any such insurance proceeds and no Default or Event of Default
then exists, the Collateral Agent shall, prior to making any other payment or
distribution hereunder, transfer to the Obligor whose Property was the subject
of such Casualty an amount in immediately available funds equal to the
difference between (A) the amount of such insurance proceeds so received and (B)
the Net Proceeds relating thereto (as set forth in a certificate executed by a
Senior Officer and delivered to the Collateral Agent), and thereafter the
remainder of such insurance proceeds shall be distributed as provided below. Any
and all amounts to be distributed as provided in this clause (a) shall be
distributed as follows:

                  (i) if the insurance proceeds with respect to such Casualty
      are in an aggregate amount less than $5,000,000 in respect of any single
      occurrence, the Net Proceeds thereof held by the Collateral Agent shall be
      immediately payable in immediately available funds directly to the
      applicable Obligor which is the primary insured on such policy (the
      "INSURED") upon receipt of a certificate executed by a Senior Officer
      which states that no Default or Event of Default then exists and such
      Obligor will use such Net Proceeds to repair or replace the Collateral
      which was the subject of such Casualty which gave rise to such Net
      Proceeds; and

                  (ii) if the insurance proceeds with respect to such Casualty
      equal or exceed $5,000,000 in respect of any single occurrence, the
      Secured Parties shall review with the Company, the Company's business
      proposal with respect to the application of the Net Proceeds thereof held
      by the Collateral Agent, which proposal the Company shall submit to the
      Secured Parties within thirty (30) Business Days of the date of the
      occurrence of the Casualty, and give due consideration to the merits and
      rationale of such proposal recognizing the integrated nature of the
      Company's facilities and operations. Within twenty (20) Business Days of
      receipt of the Company's proposal, the Requisite Parties shall, following
      review thereof, determine (which determination shall be reasonably made
      and not unduly delayed) whether such Net Proceeds shall be applied as
      provided in such proposal. If the Company shall not have received a reply
      from the Requisite Parties by the end of such twenty (20) Business Day
      period, the Company shall deliver a written notice to each of the Secured
      Parties requesting a determination as to such proposal and shall give the
      Requisite Parties an additional five (5) Business Days after the delivery
      of such second notice to deliver a written acceptance or rejection of such
      proposal. If the Requisite Parties fail to advise the Company in writing
      of their

<PAGE>

                                      -40-

      determination with respect to such proposal as provided herein prior to
      the end of such five (5) Business Day period, they shall be deemed to have
      accepted such proposal. Upon actual or deemed acceptance of such proposal,
      the Collateral Agent shall hold such Net Proceeds for disbursement in
      accordance with Section 12.3 and the Insured shall act diligently and in
      good faith to apply such Net Proceeds substantially as provided in such
      proposal. If such proposal is not accepted, then the Net Proceeds shall be
      applied as a Offered Repayment as set forth in Section 12.2 below.

            (b) Notwithstanding anything contained herein, if any Default or
Event of Default shall have occurred and be continuing, any Net Proceeds of any
such Casualty with respect to the Collateral, together with any other amounts
held by the Collateral Agent in respect of such Casualty, shall be applied as an
Offered Repayment as set forth in Section 12.2 below unless the Majority Secured
Parties and the Company agree otherwise. The Collateral Agent shall promptly
and, in any case, not more than five (5) Business Days after the receipt of any
funds hereunder satisfactorily identified to the Collateral Agent as amounts to
be applied as an Offered Repayment, inform the Obligors and the Secured Parties
in writing of such receipt and the amount thereof.

               SECTION 12.2. OFFERED REPAYMENT. Any Net Proceeds to be applied
as an Offered Repayment as provided in Section 12.1(a)(ii) or Section 12.1(b)
shall be offered pro rata to all Secured Parties as a prepayment as provided
below. Each such Offered Repayment shall be made in writing as soon as
practicable after each of the Obligors being informed, in writing, by the
Collateral Agent of their obligation to make such Offered Repayment but, in any
case, not later than ten (10) days thereafter. Each Offered Repayment shall
specify the date on which the prepayment provided therein is to be made (which
shall be a Business Day and shall not be a date more than thirty-five (35) days
after the date of the delivery of such Offered Repayment), the principal amount
of the Secured Obligations of the recipient of such Offered Repayment then being
offered to be prepaid and the amount of accrued interest to be paid thereon. To
accept or reject any Offered Repayment under this Section 12.2, in whole or in
part, any Secured Party shall cause a written notice of such acceptance or
rejection to be delivered to the Obligors not later than fifteen (15) days after
the date of receipt by such holder of such Offered Repayment, provided that, if
(a) the Obligors shall have not received a reply from a holder of such
applicable Secured Obligations by the end of such fifteen (15) day period or (b)
any such holder shall have rejected such Offered Repayment, the Obligors shall
deliver a second written notice (which shall include a description of whether
other holders of such Secured Obligations have accepted or rejected such Offered
Repayment) in respect of the relevant Offered Repayment to each such holder
described in clause (a) or (b) above and shall give each such holder an
additional ten (10) days after the delivery of such second notice to deliver a
written acceptance or rejection of such Offered Repayment (it being understood
that the failure by a holder to accept (in full or in part) such Offered
Repayment as provided herein prior to the end of the aforesaid ten (10) day
period shall be deemed to constitute a rejection of said Offered Repayment, or,
if so indicated as to any Secured Party on Schedule 14.4 or in a written notice
delivered to the Company by any Secured Party within 60 days of the date hereof,
an acceptance of such Offered Repayment). The Obligors shall inform the
Collateral Agent, in writing not less than five (5) Business Days prior to any
date fixed for the effecting of the payments contemplated by any accepted
Offered Repayment under this Section 12.2, of all amounts due in respect of each
of such accepted Offered Repayments, the payment date

<PAGE>

                                      -41-

therefor, the recipients thereof, and the payment address and payment method
required in respect of each such recipient. Upon the receipt by the Collateral
Agent of written instructions from the Obligors (or the Requisite Secured
Parties, in the event that the Obligors fail to give such notice within a
reasonable time) directing the Collateral Agent to effect the payment in
immediately available funds of accepted Offered Repayments from the Net Proceeds
then held by the Collateral Agent, as expressly provided in the immediately
preceding sentence, the Collateral Agent shall effect the payment of such
accepted Offered Repayments as so instructed. To the extent that any such Net
Proceeds shall not have been utilized to pay or prepay Secured Obligations as a
result of one or more holders of Secured Obligations rejecting (in whole or in
part) or being deemed to have rejected their respective Offered Repayments, upon
receipt of a written demand from the Obligors (or the Requisite Parties, in the
event that the Obligors fail to give such notice within a reasonable time), the
Collateral Agent shall pay such remaining Net Proceeds, together with any
interest accrued thereon, promptly to the Obligors. Each accepted Offered
Repayment in respect of any BofA Debt shall be deposited in the Special Cash
Collateral Account as a Proceeds Deposit and each other accepted Offered
Repayment pursuant to this Section 12.2 shall be made in accordance with (a)
Section 2.2(a) of each of the Note Agreements (with respect to any prepayment of
the Note Principal Obligations) but without payment of Make-Whole Amount, (b)
Section 3.6 and Section 3.4(iii)(d) of the Trade Agreement (with respect to any
prepayment of the Trade Agreement Debt) but without payment of any prepayment or
breakage fees, and (c) any one or more similar provisions in the Additional
Future Debt Documents (with respect to any prepayments of Additional Future
Debt), in each case, as certified to the Collateral Agent by the Secured Party
to whom such Offered Repayment is due. To the extent any such sections of the
Loan Documents referred to in this Section 12.2 contain notice or other
procedural provisions, such provisions are hereby seemed waived to permit
prepayments under this Section 12.2. Only upon the Collateral Agent effecting
the payment in full of all of the amounts owing in respect of the applicable
accepted Offered Repayments under this Section 12.2 will the Obligors be deemed
to have discharged the payment obligations they have under this Section 12.2
with respect to such accepted Offered Repayments. The Obligors agree that they
will instruct such Collateral Agent to effect the payment of all related Offered
Repayments to all applicable Secured Parties simultaneously. Notwithstanding the
foregoing, if, to the extent required by the operation of any provision of any
Credit Documents (it being understood that the Loan Documents outstanding on the
date hereof contain no such provision), the Obligors are prohibited from making
any Offered Repayment under such Credit Document, such Offered Repayment shall
be deemed to have been rejected by the each Secured Party who is a party to the
Credit Document containing such prohibition.

               SECTION 12.3. REMNANT INSURANCE PROCEEDS. With respect to any
proposal accepted or deemed accepted in accordance with Section 12.1(a)(ii)
whereby the Insured is entitled to be paid and use such Net Proceeds, such Net
Proceeds shall be held by the Collateral Agent for distribution in accordance
with this Section 12.3. Upon receipt of a written demand from the Insured and a
certificate certifying that no Default or Event of Default has occurred and is
continuing, the Collateral Agent shall promptly pay any Net Proceeds in
immediately available funds to the Insured to pay the costs of implementing the
Company's proposal in accordance with Section 12.1(a)(ii). Should the Net
Proceeds, if any, be insufficient to pay the entire cost of the work outlined in
such proposal, the Insured shall pay the deficiency or the entire cost as the
case may be. On the completion of all work and payment in full therefor and upon
receipt by the Collateral Agent of evidence to its

<PAGE>

                                      -42-

satisfaction that such work has been completed and paid for in full and that any
property purchased, repaired, reconstructed and restored in the course of such
work is subject to the applicable Liens under the Security Documents (subject to
any Permitted First Priority Liens), any Net Proceeds not yet disbursed to the
Insured as above provided and in the possession or under the control of the
Collateral Agent or the Secured Parties shall be remitted to the Insured.
Notwithstanding anything in this Section 12.3 to the contrary, if no Default or
Event of Default shall have occurred and be continuing, to the extent that such
Net Proceeds shall not have been utilized to pay or prepay the applicable
Secured Obligations as provided herein, the Insured may, in its discretion,
elect not to implement its proposal in connection with such Net Proceeds and, in
such event, upon notice thereof to the Secured Parties and the Collateral Agent,
shall pay any amounts they are entitled to receive under this Section 12.3 to
the Secured Parties as an Offered Repayment of the Secured Obligations as
provided in Section 12.2. The Insured will be deemed to have so elected if it
shall not have commenced implementation of such proposal within sixty (60) days
of such Net Proceeds having become available to it for such purposes.

               SECTION 12.4. NOTICE OF CASUALTY; ADJUSTING LOSS. In the event
all or any part of a Significant Real Estate Interest shall suffer a Casualty,
the Obligors will promptly give written notice thereof to the insurance carrier
and the Collateral Agent, and shall promptly provide to the Collateral Agent
such reasonable information concerning such Casualty as the Collateral Agent may
request. So long as no Default or Event of Default shall then exist, the
Obligors shall be authorized to make proof of loss and to negotiate, adjust,
compromise and settle all insurance claims and demands with respect to any such
Casualty; provided, however, that the Obligors may not adjust any claim for any
Casualty which is estimated by the Collateral Agent in good faith to exceed
$5,000,000 unless the Collateral Agent at the Collateral Agent's request, acting
at the direction of the Requisite Parties, shall have joined in such adjustment
without undue delay. If (a) there has been no adjustment of any such Casualty
within six (6) months from the date of occurrence thereof as a result of the
failure of any Obligor to diligently prosecute the applicable insurance claim or
(b) if a Default or an Event of Default has occurred and is continuing, the
Collateral Agent, acting at the direction of the Requisite Parties, shall be
authorized, but shall not be obligated, to make such proof of loss with respect
to any such Casualty and to negotiate, adjust, compromise or settle all
insurance claims and demands in respect thereof and prosecute any action arising
in connection therewith. In connection therewith, the Obligors do hereby
irrevocably authorize, empower and appoint the Collateral Agent as
attorneys-in-fact for the Obligors (which appointment is coupled with an
interest) to do any and all of the foregoing in the name and on behalf of the
Obligors. The Requisite Parties agree to act in good faith without undue delay
in issuing any such written instruction and approving any such adjustment.

               SECTION 12.5. REIMBURSEMENT OF COLLATERAL AGENT'S EXPENSES. The
Obligors shall promptly reimburse the Collateral Agent upon demand for all of
the Collateral Agent's reasonable out-of-pocket expenses (including reasonable
attorney's fees) incurred in performing its duties under this Section 12. To the
extent the Collateral Agent has not been so reimbursed by the Obligors (or
arrangements therefor made to the satisfaction of the Collateral Agent), any
disbursement to be made by the Collateral Agent pursuant to this Section 12
shall be net of all of the Collateral Agent's reasonable out-of-pocket expenses
(including reasonable attorney's fees) incurred in performing its duties under
this Section 12.

            SECTION 13. PROCEEDS FROM SALE OF ASSETS.

               SECTION 13.1. GENERAL. Notwithstanding anything in this Section
13 to the contrary, any Obligor shall be entitled and permitted to undertake any
Asset Disposition in accordance with the terms and conditions of all of the Loan
Documents. If any Obligor intends to undertake an Asset Disposition and if all
of the Loan Documents permit the Obligor to use the proceeds of such Asset
Disposition for any purpose other than the repayment or prepayment of any
Secured Obligation, then such Obligor shall include in its Asset Disposition
Certificate required to be delivered to the Collateral Agent and the Secured
Parties in accordance with Section 14.6: (i) the purpose for which the Obligor
intends to use the proceeds, (ii) the specific provisions of any covenant under
any of the Loan Documents which restrict transfer of assets and which permit
such Asset Disposition and (iii) a statement that the proceeds will be used for
such stated purpose.

               SECTION 13.2. NET PROCEEDS FROM AN ASSET DISPOSITION. To the
extent any Obligor is required or is permitted and elects to prepay the Secured
Obligations with Net Proceeds from any Asset Disposition, such Net Proceeds
shall be paid in immediately available funds to the Collateral Agent. The
Collateral Agent shall promptly and, in any case, not more than five (5)
Business Days after the receipt of any such Net Proceeds satisfactorily
identified to the Collateral Agent as Net Proceeds of an Asset Disposition,
inform the Obligors and the Secured Parties in writing of such receipt and the
amount thereof. All Net Proceeds so paid to the Collateral Agent from such Asset
Disposition shall be applied as an Offered Repayment in accordance with the
requirements of Section 13.3.

               SECTION 13.3. OFFERED REPAYMENT. With respect to the Net Proceeds
received by the Collateral Agent as a result of any Asset Disposition, the
Obligors shall, subject to Section 13.4 below, extend an Offered Repayment pro
rata to each of the holders of Secured Obligations if such Net Proceeds arise
out of the sale, transfer of other disposition of any Collateral. Each such
Offered Repayment shall be made in writing as soon as practical after the
Obligors being informed, in writing, by the Collateral Agent of its receipt of
any such Net Proceeds but, in any case, not later than ten (10) days thereafter.
Each Offered Repayment shall specify the date on which the prepayment provided
therein is to be made (which shall be a Business Day and shall not be a date
more than twenty-five (25) days after the date of the delivery of such Offered
Repayment), the principal amount of the applicable Secured Obligations of the
recipient of such Offered Repayment then being offered to be prepaid, the amount
of accrued interest to be paid thereon and the estimated Make-Whole Amount due
in respect of such prepayment as provided under the terms of the Note Documents.
To accept or reject any Offered Repayment under this Section 13.3, in whole or
in part, any Secured Party shall cause a written notice of such acceptance or
rejection to be delivered to the Obligors not later than fifteen (15) days after
the date of receipt by such holder of such Offered Repayment (it being
understood that the failure by a holder to accept in full or in part such
Offered Repayment as provided herein prior to the end of such fifteen (15) day
period shall be deemed to constitute a rejection of said Offered Repayment, or,
if so indicated as to any Secured Party on Schedule 14.4 or in a written notice
delivered to the Company by any Secured Party within 60 days of the date hereof,
an acceptance of such Offered Repayment). The Obligors shall inform the
Collateral Agent, in writing not less than five (5) Business Days prior to any
date fixed for the effecting of the payments contemplated by any

<PAGE>

                                      -44-

accepted Offered Repayment under this Section 13.3, of all amounts due in
respect of each of such accepted Offered Repayments, the payment date therefor,
the recipients thereof, and the payment address and payment method required in
respect of each such recipient. Upon the receipt by the Collateral Agent of
written instructions from each of the Obligors (or the Requisite Parties in the
event that the Obligors fail to give such notice within a reasonable time)
directing the Collateral Agent to effect the payment in immediately available
funds of accepted Offered Repayments from the Net Proceeds then held by the
Collateral Agent, as expressly provided in the immediately preceding sentence,
the Collateral Agent shall effect the payment of such accepted Offered
Repayments as so instructed. To the extent that any such Net Proceeds shall not
have been utilized to pay or prepay the applicable Secured Obligations as a
result of one or more holders of such Secured Obligations rejecting (in whole or
in part) or being deemed to have rejected their respective Offered Repayments in
respect of such Net Proceeds and upon receipt of a written demand from the
Obligors (or the Requisite Parties in the event that the Obligors fail to give
such notice within a reasonable time), the Collateral Agent shall pay such Net
Proceeds promptly to the Obligors. Each accepted Offered Repayment of the BofA
Debt shall be deposited in the Special Cash Collateral account as a Proceeds
Deposit and each other accepted Offered Repayment pursuant to this Section 13.3
shall be made in accordance with (a) Section 2.2(a) of each of the Note
Agreements (with respect to any prepayment of the Note Debt), (b) Section 3.6
and Section 3.4(iii)(d) of the Trade Agreement (with respect to any prepayment
of the Trade Agreement Debt), and (c) any one or more similar provisions in the
Additional Future Debt Documents (with respect to any prepayments of Additional
Future Debt)), in each case, as certified to the Collateral Agent by the Secured
Party to whom such payment is due. To the extent any such sections referred to
in this Section 13.3 contain notice or other procedural provisions such
provisions are hereby deemed waived to permit prepayments under this Section
13.3. Only upon the Collateral Agent's effecting of the payment in full of all
of the amounts owing in respect of the applicable accepted Offered Repayments
under this Section 13.3 will the Obligors be deemed to have discharged the
payment obligations it has under this Section 13.3 with respect to such accepted
Offered Repayments. The Obligors agree that they will instruct the Collateral
Agent to effect the payment of all related Offered Repayments to all applicable
Secured Parties simultaneously. Notwithstanding the foregoing, if, to the extent
required by the operation of any provision of any Loan Documents (it being
understood that the Loan Documents outstanding on the date hereof have no such
provision), the Obligors are prohibited from making any Offered Repayment under
such Loan Document, such Offered Repayment shall be deemed to have been rejected
by the Secured Party whose Loan Document contained the prohibition. Any amounts
held by the Collateral Agent after giving effect to all such rejected Offered
Repayments shall be released to the Obligors upon receipt of a certificate of a
Senior Officer delivered to the Collateral Agent and each of the Secured Parties
which states that (i) no Default or Event of Default then exists and (ii) such
amounts so paid to the Obligors will be used to acquire productive assets within
180 days of their receipt of such funds or applied to the prepayment of Secured
Obligations within five (5) Business Days of receipt of such funds by the
Obligors.

               SECTION 13.4. COLLATERAL AGENT EXPENSES. The Obligors shall
promptly reimburse the Collateral Agent upon demand for all of the Collateral
Agent's reasonable out-of-pocket expenses (including reasonable attorney's fees)
incurred in performing its duties under this Section 13. To the extent the
Collateral Agent has not been so reimbursed by the Obligors (or arrangements

<PAGE>

                                      -45-

therefor made to the satisfaction of the Collateral Agent), any disbursement to
be made by the Collateral Agent pursuant to this Section 13 shall be net of all
of the Collateral Agent's reasonable out-of-pocket expenses (including
reasonable attorney's fees) incurred in performing its duties under this
Section 13.

            SECTION 14. MISCELLANEOUS.

               SECTION 14.1. FURTHER ASSURANCES, ETC. BofA, each Note Holder,
Northern and each holder of Additional Future Debt and, by countersigning this
Agreement, the Company and each Guarantor, agrees to execute and deliver such
other documents and instruments, in form and substance reasonably satisfactory
to the Collateral Agent (upon instructions from the Requisite Parties), and
shall take such other action, in each case as the Collateral Agent (upon
instructions from the Requisite Parties) may reasonably request (at the sole
cost and expense of the Company which, by countersigning this Agreement, agrees
to pay such costs and expenses), to effectuate and carry out the provisions of
this Agreement including, without limitation, by recording or filing in such
places as the requesting party may reasonably deem desirable, this Agreement or
such other documents or instruments.

               SECTION 14.2. NO INDIVIDUAL ACTION; MARSHALING; ETC. No holder of
any Secured Obligations may require the Collateral Agent to take or refrain from
taking any action hereunder or under any of the Security Documents or with
respect to any of the Collateral except as and to the extent expressly set forth
in this Agreement. The Collateral Agent shall have no duty to, and the Company
and each Guarantor hereby waives any and all right to require the Collateral
Agent to, marshal any assets or otherwise to take any actions with respect to
marshaling.

               SECTION 14.3. SUCCESSORS AND ASSIGNS.

            (a) This Agreement shall be binding on and inure to the benefit of
the Collateral Agent, BofA, each of the Note Holders, Northern and each of the
holders of Additional Future Debt who shall have executed and delivered a
Joinder Agreement and their respective successors and assigns and shall be
binding on the Company and each Guarantor and their respective successors and
permitted assigns. Each of the Note Holders, BofA, Northern and each holder of
Additional Future Debt agrees that the provisions of this Agreement apply
regardless of any sale, transfer, pledge, assignment, hypothecation or other
disposition by such Note Holder, BofA, Northern or such holder of Additional
Future Debt of any Note or of any instrument or right evidencing BofA Debt,
Trade Agreement Debt or Additional Future Debt to any Person. Each Secured Party
agrees that it shall not sell, transfer, assign or otherwise dispose of any
interest in any Secured Obligation unless the buyer, transferee or assignee
assumes in writing the obligations of such Secured Party under this Agreement;
provided, however, that the foregoing shall not prohibit BofA, any Note Holder,
Northern or any holder of Additional Future Debt from pledging or otherwise
granting a security interest in any Secured Obligation so long as the pledgee or
other secured party, as a condition to its retaining or further transferring
such Secured Obligation by way of enforcement of such pledge or other security
interest, assumes or causes its transferee to assume in writing the obligations
of such Note Holder, BofA, Northern or such holder of Additional Future Debt
under this Agreement.

<PAGE>

                                      -46-

            (b) No Secured Party may sell any Secured Obligation or any interest
therein to any Affiliate of the Company (other than a sale which constitutes a
payment under a Guaranty after an Event of Default), or accept any payment of a
Secured Obligation from an Affiliate of the Company (other than payments under a
Guaranty after an Event of Default), without the consent of the Majority Secured
Parties.

               SECTION 14.4. NOTICES. All notices and other communications made
or required to be given pursuant to this Agreement or the Security Documents
shall be in writing and shall be delivered in hand, mailed by United States
registered or certified first class mail, postage prepaid, sent by overnight
courier or sent by telecopy, confirmed by delivery via courier or postal
service, addressed as set forth on Schedule 14.4 hereto or to such other address
or addresses as any such party shall specify by notice given to the other
parties. Any such notice and other communications shall be deemed to have been
duly given or made and to have become effective (i) if delivered by hand,
overnight courier or facsimile, at the time of the receipt thereof, and (ii) if
sent by registered or certified first class mail postage prepaid, on the fourth
(4th) Business Day following the mailing thereof; provided, however, that a
Notice of Actionable Default or any other notice to be delivered to the
Collateral Agent pursuant to the terms of this Agreement shall not be deemed to
have been received by a Responsible Officer of the Collateral Agent until the
Collateral Agent actually receives such notice.

               SECTION 14.5. TERMINATION; FULL RELEASE OF COLLATERAL.

            (a) The Liens created by the Security Documents, including the Liens
of the Collateral Agent, shall terminate and all right, title and interest in
the Collateral shall revert to the Company and its successors and assigns upon
payment in full in cash of all amounts owed to the Collateral Agent pursuant to
Section 5.5 and Section 5.7 and the satisfaction of each of the following four
conditions:

                  (i) receipt by the Collateral Agent from Northern of notice
      stating that either:

                        (A) the Trade Agreement Debt has been paid in full, in
            cash, and all commitments under the Trade Agreement have terminated,
            been canceled or been reduced to zero; or

                        (B) the Trade Agreement Debt no longer constitutes a
            Secured Obligation under the Security Documents; or

                        (C) the Company has entered into an Acceptable Revolving
            Credit Facility to replace a Receivables Purchase Agreement and the
            Company's unsecured debt obligations are Investment Grade; and

                  (ii) receipt by the Collateral Agent from each of the Note
      Holders of notice that either:

                        (A) the Note Debt held by such Note Holders has been
            paid in full, in cash, in accordance with the Note Agreements; or

<PAGE>

                                      -47-

                        (B) the Note Debt held by such Note Holders no longer
            constitutes a Secured Obligation under the Security Documents; or

                        (C) the Company has entered into an Acceptable Revolving
            Credit Facility to replace a Receivables Purchase Agreement and the
            Company's unsecured debt obligations are Investment Grade; and

                  (iii) receipt by the Collateral Agent from BofA of notice
      stating that:

                        (A) BofA Debt due to it has been paid in full, in cash,
            and it has no Undrawn LC/Guaranty Exposure; or

                        (B) BofA Debt due to it no longer constitutes a Secured
            Obligation under the Security Documents; or

                        (C) the Company has entered into an Acceptable Revolving
            Credit Facility to replace a Receivables Purchase Agreement and the
            Company's unsecured debt obligations are Investment Grade; and

                  (iv) receipt by the Collateral Agent from each of the holders
      of Additional Future Debt that either:

                        (A) the Additional Future Debt held by such holder or
            holders has been paid in full, in cash, in accordance with the
            Additional Future Debt Documents; or

                        (B) the Additional Future Debt held by such holder or
            holders no longer constitutes a Secured Obligation under the
            Security Documents; or

                        (C) the Company has entered into an Acceptable Revolving
            Credit Facility to replace a Receivables Purchase Agreement and the
            Company's unsecured debt obligations are Investment Grade; and

      The Secured Parties agree to provide the notices contemplated by Section
14.5(a)(i), Section 14.5(a)(ii), Section 14.5(a)(iii) and Section 14.5(a)(iv),
under the circumstances provided in such Sections for such notices to be capable
of being given, promptly upon the Company's request.

            (b) Upon the termination of the Collateral Agent's Liens and the
release of the Collateral in accordance with subsection (a) of this Section
14.5, the Collateral Agent will promptly, at the Company's written request and
expense, (i) execute and deliver to the Company such documents as the Company
shall reasonably request and to provide evidence of the termination of such
security interest, or the release of the Collateral and (ii) deliver or cause to
be delivered to the Company all property of the Company constituting Collateral
then held by Collateral Agent or any agent thereof.

                                      -48-

            (c) This Agreement shall terminate automatically when the Liens
granted under the Security Documents have terminated and the Collateral has been
released to the Company by the Collateral Agent as provided in the foregoing
provisions of this Section 14.5.

            (d) If, at any time, any payment made or value received with respect
to any Secured Obligation must be returned by the Secured Party receiving the
same upon the insolvency, bankruptcy or reorganization of the Company or any
Guarantor, or otherwise, with the effect as though such payment had not been
made or value received, the Liens in the Collateral created by the Security
Documents in favor of the Collateral Agent and the rights of the Collateral
Agent to act as agent hereunder and to receive amounts pursuant to this
Agreement shall be reinstated to the extent those rights had previously been
terminated. In such event each Secured Party agrees that it will pay to the
other Secured Parties such amounts so that, after giving effect to the payments
hereunder by all Secured Parties, the amounts received by all Secured Parties
are not in excess of the amounts to be paid to them hereunder as though any
payment so returned had not been made.

            (e) Notwithstanding the foregoing, Section 5.5, Section 5.6 and
Section 5.7 of this Agreement shall survive, and remain operative and in full
force and effect, regardless of the termination of this Agreement.

               SECTION 14.6. PARTIAL RELEASE OF COLLATERAL.

            (a) In connection with any Obligor's consummation of an Asset
Disposition in compliance with the provisions of this Agreement, the Liens of
the Collateral Agent in the Asset Disposition Collateral in respect of such
Asset Disposition shall be released and all right, title and interest therein
shall revert to such Obligor and its successors and assigns upon satisfaction of
the following conditions:

                  (i) if such Asset Disposition is not an Approved Asset
      Disposition and if the net book value of such Asset Disposition
      Collateral, together with the aggregate net book value of all other Asset
      Disposition Collateral which was the subject of an Asset Disposition
      (other than an Approved Asset Disposition) in the then current calendar
      year, is $5,000,000 or less, the Collateral Agent shall, at such Obligor's
      request and expense, release all of its Liens with respect to such Asset
      Disposition Collateral as soon as reasonably possible (but no later than
      the consummation of such Asset Disposition) provided that the Company
      shall have delivered to the Collateral Agent and to each holder of Secured
      Obligations an Asset Disposition Certificate in respect of such Asset
      Disposition at least twenty (20) days prior to the consummation of such
      Asset Disposition; or

                  (ii) if such Asset Disposition is not an Approved Asset
      Disposition and if the net book value of such Asset Disposition
      Collateral, together with the aggregate net book value of all other Asset
      Disposition Collateral which was the subject of an Asset Disposition
      (other than an Approved Asset Disposition) in the then current calendar
      year, is more than $5,000,000, the Collateral Agent shall, at the
      Company's request and expense, release all of its Liens with respect to
      such Asset Disposition Collateral no later

<PAGE>

                                      -49-

      than the consummation of such Asset Disposition; provided that (a) the
      Company shall have delivered to the Collateral Agent and to each holder of
      Secured Obligations an Asset Disposition Certificate in respect of such
      Asset Disposition at least thirty (30) days prior to the proposed
      consummation date of such Asset Disposition, and (b) the Requisite Parties
      do not instruct the Collateral Agent to not release the Asset Disposition
      Collateral within such thirty (30) day period; or

                  (iii) if such Asset Disposition is an Approved Asset
      Disposition approved by the Requisite Parties as provided in the
      definition thereof, then the Collateral Agent shall, at the Company's
      request and expense, release all of its Liens with respect to the Asset
      Disposition Collateral which is the subject of such Approved Asset
      Disposition no later than the consummation of such Asset Disposition.

      In each such instance, upon satisfaction of the foregoing conditions, the
Collateral Agent will promptly, at the Company's written request and expense;
(i) execute and deliver to the Company such documents as the Company shall
reasonably request and provide to evidence the release of its Lien in such Asset
Disposition Collateral and (ii) deliver or cause to be delivered to the
Obligors, all Property of the Obligors constituting such Asset Disposition
Collateral then held by the Collateral Agent or any agent thereof so long as, in
each such case, the Collateral Agent obtains a perfected security interest in
Collateral received as proceeds of such Asset Disposition, and it shall have
received an opinion of nationally recognized independent outside counsel to such
effect if such Collateral is real estate or property in which a security
interest is perfected by means other than the filing of a financing statement.

            (b) Whether or not instructed by the Secured Parties, the Collateral
Agent may release any Collateral and may provide any release, termination
statement or instrument of subordination required by order of a court of
competent jurisdiction.

            (c) To the extent that the Loan Documents of any party permit any
Disposition to which such party's consent is required pursuant to this Section
14.6, such party agrees to provide that consent promptly following a written
request by the Company. But nothing in this Section 14.6 shall (i) be deemed to
imply any waiver of any restriction on Dispositions under the Reimbursement
Agreements, the Note Documents, the Trade Agreement, the Additional Debt
Documents or any other Loan Document, or (ii) without the prior written consent
of the Requisite Parties, authorize the Collateral Agent in any bankruptcy case
to enter into any agreement for, or give any authorization or consent with
respect to, the post-petition usage of Collateral.

      Notwithstanding anything to the contrary in this Agreement (including
Section 14.11) or in any Security Document, nothing in this Agreement or in any
Security Document shall or shall be construed as waiving, modifying or otherwise
altering any obligation of any Secured Party to release any Collateral from the
Lien of any Security Document upon the terms and conditions contained in any
Loan Document.

               SECTION.14.7. APPLICABLE LAW. THIS AGREEMENT SHALL BE CONSTRUED
IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF ILLINOIS (WITHOUT
REFERENCE TO ITS CONFLICT OF LAWS PRINCIPLES).

                                      -50-

               SECTION 14.8. SEVERABILITY. In case any one or more of the
provisions contained in this Agreement should be invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby. The parties shall endeavor in good faith negotiations to
replace the invalid, illegal or unenforceable provisions with valid provisions
the economic effect of which comes as close as possible to that of the invalid,
illegal or unenforceable provision.

               SECTION 14.9. COUNTERPARTS. This Agreement may be executed in two
or more counterparts, each of which shall constitute an original, but all of
which, when taken together, shall constitute but one instrument.

               SECTION 14.10. SECTION HEADINGS. The section headings used herein
are for convenience of reference only and are not to affect the construction of
or be taken into consideration in interpreting this Agreement.

               SECTION 14.11. COMPLETE AGREEMENT. This Agreement constitutes the
entire agreement among the parties hereto with respect to the subject matter
hereof and supersedes and all other prior representations, negotiations,
writings, memoranda and agreements except as provided below. Except as expressly
provided herein, to the extent any provision of this Agreement supplements,
modifies or conflicts with any provision of the Trade Agreement, any
Reimbursement Agreement, any IRB Bond Guaranty, any Note Agreement or any other
Credit Document, the provisions of this Agreement shall be controlling. Nothing
in this Agreement, expressed or implied, is intended to confer upon any person
other than the parties hereto any rights or remedies under or by reason of this
Agreement.

               SECTION 14.12. ADDITIONAL FUTURE DEBT. At the request of the
Company, holders of additional unsecured indebtedness of the Company incurred in
compliance with the terms of the Loan Documents may from time to time after the
date of this Agreement become parties hereto by executing and delivering a
Joinder Agreement to this Agreement in substantially the form attached as
Exhibit A hereto. Each of the undersigned agrees that, effective from and after
the date of the execution and delivery by the Company, each Guarantor and any
holder of such additional indebtedness of a Joinder Agreement, such holder shall
be, and shall be deemed for all purposes to be, a party hereto with the same
force and effect, and subject to the same agreements, representations,
covenants, guarantees, indemnities, liabilities and obligations, as if such
holder were, effective as of such date, an original signatory to this Agreement.

contract rights or rights to the payment of money, insurance claims and
proceeds, and all general intangibles (including all payment intangibles), in
each case, other than Excluded Collateral. The Collateral Agent acknowledges
that the attachment of its security interest in any commercial tort claim of any
Obligor as original collateral is subject to such Obligor's compliance with
Section 4.8.

      3.    AUTHORIZATION TO FILE FINANCING STATEMENTS. Each Obligor hereby
irrevocably authorizes the Collateral Agent at any time and from time to time to
file in any filing office in any Uniform Commercial Code jurisdiction any
initial financing statements and amendments thereto that (a) indicate the
Collateral (i) as all assets of such Obligor or words of similar effect,
regardless of whether any particular asset comprised in the Collateral falls
within the scope of Article 9 of the Uniform Commercial Code of the State or
such jurisdiction, but specifically excluding Excluded Collateral, or (ii) as
being of an equal or lesser scope or with greater detail, and (b) provide any

Obligor is an organization, the type of organization and any organizational
identification number issued to such Obligor and, (ii) in the case of a

property to which the Collateral relates. Each Obligor agrees to furnish any
such information to the Collateral Agent promptly upon request. Each Obligor
also ratifies its authorization for the Collateral Agent to have filed in any
Uniform Commercial Code jurisdiction any like initial financing statements or
amendments thereto if filed prior to the date hereof.

      4.    OTHER ACTIONS. Further to insure the attachment and perfection of,
and the ability of the Collateral Agent to enforce, the Collateral Agent's
security interest in the Collateral (but in each instance subject to Permitted
First Priority Liens, each Obligor agrees, in each case at such Obligor's
expense, to take the following actions with respect to the following Collateral
and without limitation on such Obligor's other obligations contained in this
Agreement:

            4.1.  PROMISSORY NOTES AND TANGIBLE CHATTEL PAPER. If any Obligor
      shall, now or at any time hereafter, hold or acquire any promissory notes
      or tangible chattel paper not constituting Excluded Collateral in excess
      of $3,000,000 in the aggregate, such Obligor shall forthwith endorse,
      assign and deliver the same to the Collateral Agent, accompanied by such
      instruments of transfer or assignment duly executed in blank as the
      Collateral Agent may from time to time specify; provided, however, that
      any such promissory note or tangible chattel paper shall be released and
      returned to the Obligors (a) pursuant to the conditions set forth in
      Sections 14.5 or 14.6 of the Intercreditor Agreement or (b) at such time
      that the obligations

                                       3
<PAGE>

      evidenced by such promissory note or tangible chattel paper have
      terminated or have been satisfied and the Obligors shall have certified in
      writing to the Collateral Agent that such termination or satisfaction has
      occurred.

            4.2.  DEPOSIT ACCOUNTS. For each deposit account that any Obligor,
      now or at any time hereafter, opens or maintains (other than accounts (i)
      opened or maintained in connection with Securitization Transactions or
      (ii) which do not include proceeds of Collateral or funds generated from
      the sale of products or services by any Obligor), such Obligor shall, at
      the Collateral Agent's request and option, pursuant to an agreement in
      form and substance satisfactory to the Collateral Agent, use its
      reasonable best efforts to cause the depositary bank to agree to comply
      without further consent of such Obligor, at any time following the
      occurrence and during the continuance of an Event of Default with
      instructions from the Collateral Agent to such depositary bank directing
      the disposition of funds from time to time credited to such deposit
      account. The Collateral Agent agrees with the Obligors that the Collateral
      Agent shall not give any such instructions or withhold any withdrawal
      rights from the Obligors, unless an Event of Default has occurred and is
      continuing, or, would occur if effect were given to any withdrawal not
      otherwise permitted by each of the Credit Documents. The provisions of
      this paragraph shall not apply to (i) a deposit account for which the
      Collateral Agent is the depositary bank and is in automatic control, and
      (ii) any deposit accounts specially and exclusively used for payroll,
      payroll taxes and other employee wage and benefit payments to or for the
      benefit of any Obligor's salaried employees.

            4.3.  INVESTMENT PROPERTY. If any Obligor shall, now or at any time
      hereafter, hold or acquire any one or more certificated securities not
      evidencing or constituting Excluded Collateral with a fair market value in
      excess of $100,000, in the aggregate for all such certificated securities,
      such Obligor shall forthwith endorse, assign and deliver the same to the
      Collateral Agent, accompanied by such instruments of transfer or
      assignment duly executed in blank as the Collateral Agent may from time to
      time specify. If any securities (not evidencing or constituting Excluded
      Collateral) now or hereafter acquired by such Obligor are uncertificated
      and are issued to such Obligor or its nominee directly by the issuer
      thereof, the Company shall immediately notify the Collateral Agent thereof
      and, at the Collateral Agent's request and option, pursuant to an
      agreement in form and substance satisfactory to the Collateral Agent, use
      its reasonable efforts to cause the issuer to agree to comply without
      further consent of such Obligor or such nominee, at any time following the
      occurrence and during the continuance of an Event of Default with
      instructions from the Collateral Agent as to such securities. If any
      securities, whether certificated or uncertificated, or other investment
      property now or hereafter acquired by any Obligor (not evidencing or
      constituting Excluded Collateral) are held by any Obligor or its

                                       4
<PAGE>

      nominee through a securities intermediary or commodity intermediary, such
      Obligor shall immediately notify the Collateral Agent thereof and, at the
      Collateral Agent's request and option, pursuant to an agreement in form
      and substance satisfactory to the Collateral Agent, use its reasonable
      efforts to cause such securities intermediary or (as the case may be)
      commodity intermediary to agree to comply, in each case without further
      consent of such Obligor or such nominee, at any time with entitlement
      orders or other instructions from the Collateral Agent, subject to the
      provisions of this Section 4.3 noted below, to such securities
      intermediary as to such securities or other investment property, or (as
      the case may be) to apply any value distributed on account of any
      commodity contract as directed by the Collateral Agent to such commodity
      intermediary, subject to the provisions of this Section 4.3 noted below.
      The Collateral Agent agrees with the Obligors that the Collateral Agent
      shall not give any such entitlement orders or instructions or directions
      to any such issuer, securities intermediary or commodity intermediary, and
      shall not withhold its consent to the exercise of any withdrawal or
      dealing rights by the Obligors, unless an Event of Default has occurred
      and is continuing or would occur, after giving effect to any such
      investment and withdrawal rights not otherwise permitted by each of the
      Credit Documents. The provisions of this paragraph shall not apply to any
      financial assets credited to a securities account for which the Collateral
      Agent is the securities intermediary.

            4.4.  PLEDGED INTEREST; LIMITATION ON ACTIONS. The parties hereto
      acknowledge that Castle SPFD, LLC, a Delaware limited liability company
      (the "Receivables Seller"), has entered into a structured receivables
      purchase transaction with General Electric Capital Corporation, as
      purchaser and agent (the "RECEIVABLES AGENT") pursuant to that certain
      Receivables Purchase and Servicing Agreement, dated as of December 26,
      2002 among the Receivables Agent, the Receivables Seller, Castle IND MGR,
      Inc., a Delaware corporation, as independent Member, the Company, as
      master servicer, Total Plastics, Inc., a Michigan corporation, as
      servicer, and Oliver Steel Plate Co., a Delaware corporation, as servicer
      (as amended, restated or otherwise modified from time to time, the
      "PURCHASE AGREEMENT"), pursuant to which the Receivables Agent has agreed
      to purchase interests in the Receivables and Related Security (as defined
      therein). To induce the Receivables Agent to permit the pledge of the
      membership interest of the Receivables Seller (the "PLEDGED COLLATERAL"),
      the parties hereto agree to the following limitations. Capitalized terms
      used in this Section 4.4 and not otherwise defined herein shall have the
      meanings ascribed thereto in the A/R Intercreditor Agreement.

                  (a)   Anything herein or in the Credit Documents to the
            contrary notwithstanding, so long as the Receivables Seller has any
            assets that are Receivables Assets:

                                       5
<PAGE>

                        (i) Until the date on which the Purchaser Interest and
                  all other amounts owed under the Related Documents have been
                  paid in full in cash in accordance with the terms of the
                  Related Documents, the Collateral Agent, for itself and as
                  agent for the Secured Parties, agrees that, upon exercising
                  its rights with respect to the Pledged Collateral, it will not
                  exercise any rights to vote the Pledged Collateral or
                  otherwise control the actions and operations of the
                  Receivables Seller with respect to any matters, except (i) to
                  vote in favor of a prepayment or termination of the Purchase
                  Agreement in accordance with its terms and (ii) to vote in
                  favor of receiving payment of money or other distribution,
                  and, until the Purchaser Interest and all other amounts owed
                  under the Related Documents have been paid in full in cash as
                  described above, the Collateral Agent's rights will be limited
                  to receiving payments of money and other distributions on the
                  Pledged Collateral which, pursuant to the terms of the Related
                  Documents, are allowed to be distributed on account of the
                  Pledged Collateral. Without limiting the foregoing, the
                  Collateral Agent shall not vote the Pledged Collateral or
                  otherwise exercise control over the Receivables Seller so as
                  to cause the Receivables Seller: (A) to violate or breach any
                  term or provision in any Related Documents, (B) to make
                  payments of money or other distributions on such Pledged
                  Collateral except as described above, (C) to amend or alter
                  any of the Receivables Seller's organizational documents, or
                  (D) to incur any debt other than as expressly permitted under
                  the Related Documents; and

                        (ii) The provisions of this Section 4.4 shall continue
                  to be effective or be reinstated, as the case may be, if at
                  any time any payment of the Purchaser Interest or any other
                  amounts owed under the Related Documents is rescinded or must
                  otherwise be returned by the Receivables Agent or the
                  Purchaser upon the insolvency, bankruptcy or reorganization of
                  the Receivables Seller or otherwise, all as though such
                  payment had not been made.

                  (b) The Receivables Agent shall be a third-party beneficiary
            with respect to this Section 4.4.

                  (c) So long as the Purchaser Interest and all other amounts
            owed under the Related Documents have not been paid in full in cash
            in accordance with the terms of the Related Documents, this Section
            4.4 shall not be amended, modified or supplemented without the prior
            written consent of the Receivables Agent, which consent shall be at
            the

                                       6
<PAGE>

            sole discretion of the Receivables Agent, and the provisions of this
            Section 4.4 shall be contained in any agreement that amends and
            restates this Security Agreement. The Collateral Agent and the
            Secured Parties agree that no such party shall enter into any
            additional agreement that would adversely affect the rights of the
            Receivables Agent as provided hereunder.

            4.5.  COLLATERAL IN THE POSSESSION OF A BAILEE. If any Collateral
      constituting Bailment Threshold Property is, now or at any time hereafter,
      in the possession of a bailee, the Obligors shall promptly notify the
      Collateral Agent thereof and, at the Collateral Agent's request and
      option, shall use its reasonable efforts to promptly obtain an
      acknowledgement from the bailee, in form and substance satisfactory to the
      Collateral Agent, that the bailee holds such Collateral for the benefit of
      the Collateral Agent and such bailee's agreement to comply, without
      further consent of the Obligors, at any time with instructions of the
      Collateral Agent as to such Collateral. The Collateral Agent agrees with
      each Obligor that the Collateral Agent shall not give any such
      instructions unless an Event of Default has occurred and is continuing or
      would occur after taking into account any action by the Obligors with
      respect to the bailee.

                                       7
<PAGE>

            4.6.  ELECTRONIC CHATTEL PAPER AND TRANSFERABLE RECORDS. If any
      Obligor, now or at any time hereafter, holds or acquires an interest in
      any electronic chattel paper or any "transferable record," as that term is
      defined in Section 201 of the federal Electronic Signatures in Global and
      National Commerce Act, or in Section 16 of the Uniform Electronic
      Transactions Act as in effect in any relevant jurisdiction, in each case,
      not constituting Excluded Collateral, such Obligor shall promptly notify
      the Collateral Agent thereof and, at the request and option of the
      Collateral Agent, shall take such action as the Collateral Agent may
      reasonably request to vest in the Collateral Agent control, under Section
      9-105 of the Uniform Commercial Code, of such electronic chattel paper or
      control under Section 201 of the federal Electronic Signatures in Global
      and National Commerce Act or, as the case may be, Section 16 of the
      Uniform Electronic Transactions Act, as so in effect in such jurisdiction,
      of such transferable record. The Collateral Agent agrees with each of the
      Obligors that the Collateral Agent will arrange, pursuant to procedures
      satisfactory to the Collateral Agent and so long as such procedures will
      not result in the Collateral Agent's loss of control, for the Obligors to
      make alterations to the electronic chattel paper or transferable record
      permitted under UCC Section 9-105 or, as the case may be, Section 201 of
      the federal Electronic Signatures in Global and National Commerce Act or
      Section 16 of the Uniform Electronic Transactions Act for a party in
      control to make without loss of control, unless an Event of Default has
      occurred and is continuing or would occur after taking into account any
      action by any Obligor with respect to such electronic chattel paper or
      transferable record.

            4.7.  LETTER-OF-CREDIT RIGHTS. If any Obligor is, now or at any time
      hereafter, a beneficiary under a letter of credit in a face amount in
      excess of $500,000, such Obligor shall promptly notify the Collateral
      Agent thereof and, at the request and option of the Collateral Agent, such
      Obligor shall, pursuant to an agreement in form and substance satisfactory
      to the Collateral Agent, use its reasonable efforts to either (a) arrange
      for the issuer and any confirmer of such letter of credit to consent to a
      collateral assignment to the Collateral Agent of the proceeds of the
      letter of credit or (b) arrange for the Collateral Agent to become the
      transferee beneficiary of the letter of credit, with the Collateral Agent
      agreeing, in each case, that the proceeds of the letter of credit are to
      be applied as provided in the Intercreditor Agreement.

            4.8.  COMMERCIAL TORT CLAIMS. If any Obligor shall, now or at any
      time hereafter, hold or acquire a commercial tort claim in an amount in
      excess of $500,000, such Obligor shall immediately notify the Collateral
      Agent in a writing signed by such Obligor of the particulars thereof and
      grant to the Collateral Agent, for the benefit of the Secured Parties and
      the Collateral Agent, in such writing a security interest therein and in
      the

                                       8
<PAGE>

      proceeds thereof, all upon the terms of this Agreement, with such writing
      to be in form and substance satisfactory to the Collateral Agent.

            4.9.  OTHER ACTIONS AS TO ANY AND ALL COLLATERAL. Each Obligor
      further agrees, upon the request of the Collateral Agent and at the
      Collateral Agent's option, to take any and all other actions as the
      Collateral Agent may reasonably determine to be necessary or useful for
      the attachment, and perfection of, and the ability of the Collateral Agent
      to enforce, the Collateral Agent's security interest in any and all of the
      Collateral, including, without limitation, (a) executing, delivering and,
      where appropriate, filing financing statements and amendments relating
      thereto under the Uniform Commercial Code, to the extent, if any, that any
      Obligor's signature thereon is required therefor, (b) causing the
      Collateral Agent's name to be noted as secured party on any certificate of
      title for a titled good with a book value in excess of $50,000 if such
      notation is a condition to attachment, perfection of, or ability of the
      Collateral Agent to enforce, the Collateral Agent's security interest in
      such Collateral, (c) complying with any provision of any statute,
      regulation or treaty of the United States as to any Collateral if
      compliance with such provision is a condition to attachment, perfection,
      or ability of the Collateral Agent to enforce, the Collateral Agent's
      security interest in such Collateral, (d) using commercially reasonable
      efforts to obtain governmental and other third party waivers, consents and
      approvals, in form and substance reasonably satisfactory to the Collateral
      Agent, including, without limitation, any consent of any licensor, lessor
      or other person obligated on Collateral, and (e) taking all actions under
      any earlier versions of the Uniform Commercial Code or under any other
      law, as reasonably determined by the Collateral Agent to be applicable in
      any relevant Uniform Commercial Code or other jurisdiction, including any
      foreign jurisdiction.

      5.    RELATION TO OTHER SECURITY DOCUMENTS. The provisions of this
Agreement supplement the provisions of any real estate mortgage or deed of trust
granted by the Company to the Collateral Agent, for the benefit of the Secured
Parties and the Collateral Agent, and which secures the payment or performance
of any of the Obligations. Nothing contained in any such real estate mortgage or
deed of trust shall derogate from any of the rights or remedies of the
Collateral Agent or any of the Secured Parties hereunder. In addition to the
provisions of this Agreement being so read and construed with any such mortgage
or deed of trust, the provisions of this Agreement shall be read and construed
with the other Security Documents referred to below in the manner so indicated.

            5.1.  STOCK PLEDGE AGREEMENT. Concurrently herewith the Company is
      executing and delivering to the Collateral Agent, for the benefit of the
      Secured Parties, a stock pledge agreement pursuant to which the Company is
      pledging to the Collateral Agent all of the shares of the capital stock of
      the Company's subsidiary or subsidiaries which are Guarantors. Such
      pledge(s)

                                       9

      or all of the Obligors will execute and deliver to the Collateral Agent,

      which each Obligor will pledge to the Collateral Agent all of its
      respective interests in its deposit accounts other than such accounts
      excluded from the operation of Section 4.2 above. Such pledge shall be

      collateral and security agreement pursuant to which each such Obligor will

      trademarks in which such Obligor has an interest. Such pledge shall be
      governed by the terms of such trademark and collateral and security
      agreement and not by the terms of this Agreement, other than Section 2
      hereof.

created hereby, (e) all other information set forth on the Perfection
Certificate pertaining to the Collateral is accurate and complete in all
material respects, and (f) there has been no change in any of such information
since the date on which the Perfection Certificate was signed by the Obligors.

      9.    COVENANTS CONCERNING COLLATERAL, ETC. Each Obligor further covenants
with the Secured Parties and the Collateral Agent as follows: (a) (except as
permitted by clause (h) and except for Collateral not constituting Bailment
Threshold Property), the Collateral, to the extent not delivered to the
Collateral Agent pursuant to Section 4, will be kept at those locations listed
on the Perfection Certificate and none of the Obligors will remove the
Collateral from such locations, without providing at least 30 days prior written
notice to the Collateral Agent, (b) except for the security interest herein
granted and Liens permitted by each of the Credit Documents or the Intercreditor
Agreement, one or more of the Obligors shall be the owner of the Collateral free
from any right or claim of any other Person (other than Joint Venture Rights) or
any Lien, and each of the Obligors shall defend the same against all claims and
demands of all Persons at any time claiming the same or any interests therein
adverse to the Collateral Agent or any of the Secured Parties, (c) no Obligor
shall pledge, mortgage or create, or suffer to exist any right of any Person in
or claim by any Person to the Collateral, or any Lien in the Collateral in favor
of any Person, other than the Collateral Agent except for Liens permitted by
each of the Credit Documents and the Intercreditor Agreement, (d) each of the
Obligors will keep the Collateral in good order and repair and will not use the
same in violation of law (to the extent that any failure to so operate could
result in or cause to occur a material adverse impairment to the Collateral or
the Lien created

                                       11
<PAGE>

hereby) and will comply, in all material respects, with the terms of any policy
of insurance thereon, (e) each of the Obligors will permit the Collateral Agent,
or its designee, to inspect the Collateral in its possession at any reasonable
time and to take all reasonable steps to permit the same with respect to any
Collateral in the possession of Persons other than the Obligors, (f) each of the
Obligors will pay promptly when due all taxes, assessments, governmental charges
and levies upon the Collateral or incurred in connection with the use or
operation of the Collateral or incurred in connection with this Agreement other

to operate, its business in compliance with all applicable provisions of the
federal Fair Labor Standards Act, as amended, and with all applicable provisions
of federal, state and local statutes and ordinances dealing with the control,
shipment, storage or disposal of hazardous materials or substances to the extent
that any failure to so operate could result in or cause to occur a material
adverse impairment to the Collateral or the Lien created hereby, and (h) none of
the Obligors will sell or otherwise dispose, or offer to sell or otherwise
dispose, of the Collateral or any interest therein except for sales of inventory
in the ordinary course of business and, so long as no Default or Event of
Default then exists, sales or other dispositions as otherwise permitted by each
of the Credit Documents. Each of the Secured Parties agrees to instruct the
Collateral Agent to release its security interest in the Collateral in
connection with any such sale or disposition pursuant to the terms of the
Intercreditor Agreement.

      10.   INSURANCE.

            10.1. MAINTENANCE OF INSURANCE. Each Obligor will maintain with
      financially sound and reputable insurers insurance with respect to its
      properties and business against such casualties and contingencies as shall
      be in accordance with general practices of businesses engaged in similar
      activities in similar geographic areas. Such insurance shall be in such
      minimum amounts that no Obligor will be deemed a co-insurer under
      applicable insurance laws, regulations and policies and otherwise shall be
      in such amounts, contain such terms, be in such forms and be for such
      periods as may be reasonably satisfactory to the Collateral Agent. All
      proceeds of insurance shall be paid and distributed in accordance with the
      terms of the Intercreditor Agreement. Without limiting the foregoing, each
      Obligor will, in accordance with prudent and reasonable business
      standards, (a) keep all of its physical property insured with casualty or
      physical hazard insurance on an "all risks" basis, with broad form flood
      and earthquake coverages and electronic data processing coverage, (b)
      maintain all such workers' compensation or similar insurance as may be
      required by law and (c) maintain, in amounts equal to those generally
      maintained by businesses engaged in similar activities in similar
      geographic areas: (i) general public liability insurance against claims of
      bodily injury, death or property damage occurring, on, in or about the
      properties of each Obligor; (ii) business interruption insurance; and
      (iii) product liability insurance.

                                       12
<PAGE>

            10.2. INSURANCE PROCEEDS. The proceeds of any casualty insurance in
      respect of any casualty loss of any of the Collateral shall be paid and
      disbursed in accordance with the terms of the Intercreditor Agreement.

            10.3. CONTINUATION OF INSURANCE. All policies of insurance shall
      provide for at least 30 days prior written cancellation notice to the
      Collateral Agent. In the event of failure by any Obligor to provide and
      maintain insurance as herein provided, the Collateral Agent may, at its
      option, provide such insurance and charge the amount thereof to any one or
      more of the Obligors. Each Obligor shall furnish the Collateral Agent with
      certificates of insurance and policies evidencing compliance with the
      foregoing insurance provision.

      11.   COLLATERAL PROTECTION EXPENSES; PRESERVATION OF COLLATERAL.

            11.1. EXPENSES INCURRED BY COLLATERAL AGENT. In the Collateral
      Agent's discretion at any time following the occurrence and during the
      continuance of an Event of Default, if any Obligor fails to do so, the
      Collateral Agent may discharge taxes and other encumbrances at any time
      levied or placed on any of the Collateral, maintain any of the Collateral,
      make repairs thereto and pay any necessary filing fees or insurance
      premiums. Each Obligor agrees to reimburse the Collateral Agent on demand
      for all expenditures so made. The Collateral Agent shall have no
      obligation to any Obligor to make any such expenditures, nor shall the
      making thereof be construed as a waiver or cure of any Default or Event of
      Default.

            11.2. COLLATERAL AGENT'S OBLIGATIONS AND DUTIES. Anything herein to
      the contrary notwithstanding, each Obligor shall remain obligated and
      liable under each contract or agreement comprised in the Collateral to be
      observed or performed by such Obligor thereunder. Neither the Collateral
      Agent nor any Secured Party shall have any obligation or liability under
      any such contract or agreement by reason of or arising out of this
      Agreement or the receipt by the Collateral Agent or any Secured Party of
      any payment relating to any of the Collateral, nor shall the Collateral
      Agent or any Secured Party be obligated in any manner to perform any of
      the obligations of any Obligor under or pursuant to any such contract or
      agreement, to make inquiry as to the nature or sufficiency of any payment
      received by the Collateral Agent or any Secured Party in respect of the
      Collateral or as to the sufficiency of any performance by any party under
      any such contract or agreement, to present or file any claim, to take any
      action to enforce any performance or to collect the payment of any amounts
      which may have been assigned to the Collateral Agent or to which the
      Collateral Agent or any Secured Party may be entitled at any time or
      times. The Collateral Agent's sole duty with respect to the custody, safe
      keeping and physical preservation of the Collateral in its possession,
      under Section 9-207 of the Uniform Commercial

                                       13
<PAGE>

      Code of the State or otherwise, shall be to deal with such Collateral in
      the same manner as the Collateral Agent deals with similar property for
      its own account.

      12.   SECURITIES AND DEPOSITS. The Collateral Agent may at any time
following and during the continuance of an Event of Default, at its option,
transfer to itself or any nominee any securities constituting Collateral,
receive any income thereon and hold such income as additional Collateral or
apply it to the Obligations pursuant to the terms of the Intercreditor
Agreement. Whether or not any Obligations are due, the Collateral Agent may
following and during the continuance of an Event of Default demand, sue for,
collect, or make any settlement or compromise which it deems desirable with
respect to the Collateral.

      13.   NOTIFICATION TO ACCOUNT DEBTORS AND OTHER PERSONS OBLIGATED ON
COLLATERAL. If an Event of Default shall have occurred and be continuing, each
of the Obligors shall, at the request and option of the Collateral Agent, notify
account debtors with respect to the Collateral and other Persons obligated on
any of the Collateral of the security interest of the Collateral Agent in any
account, chattel paper, general intangible, instrument or other Collateral and
that payment thereof is to be made directly to the Collateral Agent or to any
financial institution designated by the Collateral Agent as the Collateral
Agent's agent therefor, and the Collateral Agent may itself, if an Event of
Default shall have occurred and be continuing, without notice to or demand upon
any Obligor, so notify account debtors and other Persons obligated on
Collateral. After the making of such a request or the giving of any such
notification, the Obligors shall hold any proceeds of collection of accounts,
chattel paper, general intangibles, instruments and other Collateral received by
any Obligor as trustee for the Collateral Agent, for the benefit of the Secured
Parties and the Collateral Agent, without commingling the same with other funds
of any one or more of the Obligors and shall turn the same over to the
Collateral Agent in the identical form received, together with any necessary
endorsements or assignments. The Collateral Agent shall apply the proceeds of
collection of accounts, chattel paper, general intangibles, instruments and
other Collateral received by the Collateral Agent to the Secured Obligations as
contemplated by the Intercreditor Agreement.

      14.   POWER OF ATTORNEY.

            14.1. APPOINTMENT AND POWERS OF COLLATERAL AGENT. Each Obligor
      hereby irrevocably constitutes and appoints the Collateral Agent and any
      officer or agent thereof, with full power of substitution, as its true and
      lawful attorneys-in-fact with full irrevocable power and authority in the
      place and stead of each such Obligor or in the Collateral Agent's own
      name, for the purpose of carrying out the terms of this Agreement, to take
      any and all appropriate action and to execute any and all documents and
      instruments that may be necessary or useful to accomplish the purposes of
      this Agreement

                                       14
<PAGE>

and, without limiting the generality of the foregoing, hereby gives said
attorneys the power and right, on behalf of such Obligor, without notice to or
assent by any such Obligor, to do the following:

            (a)   upon the occurrence and during the continuance of an Event of
      Default, generally to sell, transfer, pledge, make any agreement with
      respect to or otherwise dispose of or deal with any of the Collateral in
      such manner as is consistent with the Uniform Commercial Code of the State
      and as fully and completely as though the Collateral Agent were the
      absolute owner thereof for all purposes, and to do, at the Obligors'
      expense, at any time, or from time to time, all acts and things which the
      Collateral Agent deems necessary or useful to protect, preserve or realize
      upon the Collateral and the Collateral Agent's security interest therein,
      in order to effect the intent of this Agreement, all no less fully and
      effectively as such Obligor might do, including, without limitation, (i)
      the filing and prosecuting of registration and transfer applications with
      the appropriate federal, state or local agencies or authorities with
      respect to trademarks, copyrights and patentable inventions and processes,
      (ii) upon written notice to such Obligor, the exercise of voting rights
      with respect to voting securities, which rights may be exercised, if the
      Collateral Agent so elects, with a view to causing the liquidation of
      assets of the issuer of any such securities and (iii) the execution,
      delivery and recording, in connection with any sale or other disposition
      of any Collateral, of the endorsements, assignments or other instruments
      of conveyance or transfer with respect to such Collateral; and

            (b)   to the extent that such Obligor's authorization given in
      Section 3 is not sufficient, to file such financing statements with
      respect hereto, with or without such Obligor's signature, or a photocopy
      of this Agreement in substitution for a financing statement, as the
      Collateral Agent may deem appropriate and to execute in such Obligor's
      name such financing statements and amendments thereto and continuation
      statements which may require the signature of such Obligor.

      14.2. RATIFICATION BY THE OBLIGORS. To the extent permitted by law, each
Obligor hereby ratifies all that said attorneys shall lawfully do or cause to be
done by virtue hereof. This power of attorney is a power coupled with an
interest and is irrevocable.

      14.3. NO DUTY ON COLLATERAL AGENT. The powers conferred on the Collateral
Agent hereunder are solely to protect the interests of the Collateral Agent and
the Secured Parties in the Collateral and shall not impose any duty upon the
Collateral Agent to exercise any such powers. The

                                       15
<PAGE>

      Collateral Agent shall be accountable only for the amounts that it
      actually receives as a result of the exercise of such powers, and neither
      it nor any of its officers, directors, employees or agents shall be
      responsible to any Obligor or to the Secured Parties for any act or
      failure to act, except for the Collateral Agent's own gross negligence or
      willful misconduct.

      15.   RIGHTS AND REMEDIES. If an Event of Default shall have occurred and
be continuing, subject to the terms and conditions of the Intercreditor
Agreement, the Collateral Agent, without any other notice to or demand upon any
Obligor, shall have in any jurisdiction in which enforcement hereof is sought,
in addition to all other rights and remedies, the rights and remedies of a
secured party under the Uniform Commercial Code of the State and any additional
rights and remedies as may be provided to a secured party in any jurisdiction in
which Collateral is located, including, without limitation, the right to take
possession of the Collateral, and for that purpose the Collateral Agent may, so
far as any one or more of the Obligors can give authority therefor, enter upon
any premises on which the Collateral may be situated and remove the same
therefrom. The Collateral Agent may in its discretion require each Obligor to
assemble all or any part of the Collateral at such location or locations within
the jurisdiction(s) of such Obligor's principal office(s) or at such other
locations as the Collateral Agent may reasonably designate. 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 shall give to
the Obligors at least ten (10) days prior written notice to it of the time and
place of any public sale of Collateral or of the time after which any private
sale or any other intended disposition is to be made. Each Obligor hereby
acknowledges that ten (10) days prior written notice of such sale or sales shall
be reasonable notice. In addition, to the fullest extent permitted by applicable
law, each Obligor waives any and all rights that it may have to a judicial
hearing in advance of the enforcement of any of the Collateral Agent's rights
and remedies hereunder, including, without limitation, its right following and
during the continuance of an Event of Default to take immediate possession of
the Collateral and to exercise its rights and remedies with respect thereto.

      16.   STANDARDS FOR EXERCISING RIGHTS AND REMEDIES. To the extent that
applicable law imposes duties on the Collateral Agent to exercise remedies in a
commercially reasonable manner, each Obligor acknowledges and agrees that it is
not commercially unreasonable for the Collateral Agent (a) to fail to incur
expenses reasonably deemed significant by the Collateral Agent to prepare
Collateral for disposition or otherwise to fail to complete raw material or work
in process into finished goods or other finished products for disposition, (b)
to fail to obtain third party consents for access to Collateral to be disposed
of, or to obtain or, if not required by other law, to fail to obtain
governmental or third party consents for the collection or disposition of
Collateral to be collected or disposed of, (c) to fail to exercise collection
remedies against account debtors or other persons obligated on Collateral or to
fail to remove Liens on or any adverse claims against Collateral, (d)

                                       16
<PAGE>

to exercise collection remedies against account debtors and other Persons
obligated on Collateral directly or through the use of collection agencies and
other collection specialists, (e) to advertise dispositions of Collateral
through publications or media of general circulation, whether or not the
Collateral is of a specialized nature, (f) to contact other Persons, whether or
not in the same business as any of the Obligors, for expressions of interest in
acquiring all or any portion of the Collateral, (g) to hire one or more
professional auctioneers to assist in the disposition of Collateral, whether or
not the Collateral is of a specialized nature, (h) to dispose of Collateral by
utilizing Internet sites that provide for the auction of assets of the types
included in the Collateral or that have the reasonable capability of doing so,
or that match buyers and sellers of assets, (i) to dispose of assets in
wholesale rather than retail markets, (j) to disclaim disposition warranties,
(k) to purchase insurance or credit enhancements to insure the Collateral Agent
against risks of loss, collection or disposition of Collateral or to provide to
the Collateral Agent a guaranteed return from the collection or disposition of
Collateral, or (l) to the extent deemed appropriate by the Collateral Agent, to
obtain the services of brokers, investment bankers, consultants and other
professionals to assist the Collateral Agent in the collection or disposition of
any of the Collateral. Each Obligor acknowledges that the purpose of this
Section 16 is to provide non-exhaustive indications of what actions or omissions
by the Collateral Agent would fulfill the Collateral Agent's duties under the
Uniform Commercial Code of the State or any other relevant jurisdiction in the
Collateral Agent's exercise of remedies against the Collateral and that other
actions or omissions by the Collateral Agent shall not be deemed to fail to
fulfill such duties solely on account of not being indicated in this Section 16.
Without limitation upon the foregoing, nothing contained in this Section 16
shall be construed to grant any rights to any Obligor or to impose any duties on
the Collateral Agent that would not have been granted or imposed by this
Agreement or by applicable law in the absence of this Section 16.

      17.   NO WAIVER BY COLLATERAL AGENT, ETC. The Collateral Agent shall not
be deemed to have waived any of its rights and remedies in respect of the
Obligations or the Collateral unless such waiver shall be in writing and signed
by the Collateral Agent. No delay or omission on the part of the Collateral
Agent in exercising any right or remedy shall operate as a waiver of such right
or remedy or any other right or remedy. A waiver on any one occasion shall not
be construed as a bar to or waiver of any right or remedy on any future
occasion. All rights and remedies of the Collateral Agent with respect to the
Obligations or the Collateral, whether evidenced hereby or by any other
instrument or papers, shall be cumulative and may be exercised singularly,
alternatively, successively or concurrently at such time or at such times as the
Collateral Agent deems expedient.

      18.   SURETYSHIP WAIVERS BY THE OBLIGORS. Each Obligor waives demand,
notice, protest, notice of acceptance of this Agreement, notice of loans made,
credit extended, Collateral received or delivered or other action taken in
reliance hereon and all other demands and notices of any description. With
respect to both the

                                       17
<PAGE>

Obligations and the Collateral, each Obligor assents to any extension or
postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of or failure to perfect any security interest
in any Collateral, to the addition or release of any party or Person primarily
or secondarily liable, to the acceptance of partial payment thereon and the
settlement, compromising or adjusting of any thereof, all in such manner and at
such time or times as the Collateral Agent may deem advisable. The Collateral
Agent shall have no duty as to the collection or protection of the Collateral or
any income therefrom, the preservation of rights against prior parties, or the
preservation of any rights pertaining thereto beyond the safe custody thereof as
set forth in Section 11.2. Each Obligor further waives any and all other
suretyship defenses.

      19.   MARSHALLING. Neither the Collateral Agent nor any Secured Party
shall be required to marshal any present or future collateral security
(including but not limited to the Collateral) for, or other assurances of
payment of, the Obligations or any of them or to resort to such collateral
security or other assurances of payment in any particular order, and all of the
rights and remedies of the Collateral Agent or any Secured Party hereunder and
of the Collateral Agent or any Secured Party in respect of such collateral
security and other assurances of payment shall be cumulative and in addition to
all other rights and remedies, however existing or arising. To the extent that
it lawfully may, each Obligor hereby agrees that it will not invoke any law
relating to the marshalling of collateral which might cause delay in or impede
the enforcement of the Collateral Agent's rights and remedies under this
Agreement or under any other instrument creating or evidencing any of the
Obligations or under which any of the Obligations is outstanding or by which any
of the Obligations is secured or payment thereof is otherwise assured, and, to
the extent that it lawfully may, the Company hereby irrevocably waives the
benefits of all such laws.

      20.   PROCEEDS OF DISPOSITIONS; EXPENSES. Each Obligor shall pay to the
Collateral Agent on demand any and all expenses, including reasonable attorneys'
fees and disbursements, incurred or paid by the Collateral Agent in protecting,
preserving or enforcing the Collateral Agent's rights and remedies under or in
respect of any of the Obligations or any of the Collateral. After deducting all
of said expenses, the residue of any proceeds of collection or sale or other
disposition of Collateral shall, to the extent actually received in cash, be
applied to the payment of the Obligations in such order or preference as is
provided in the Intercreditor Agreement. Upon the final payment and satisfaction
in full of all of the Obligations and after making any payments required by
Sections 9-608(a)(1)(C) or 9-615(a)(3) of the Uniform Commercial Code of the
State, any excess shall be returned to the Obligors. In the absence of final
payment and satisfaction in full of all of the Obligations, each of the Obligors
shall remain liable for any deficiency.

      21.   OVERDUE AMOUNTS. Until paid, all amounts due and payable by any one
or more of the Obligors hereunder shall (a) be a debt secured by the Collateral

                                       18
<PAGE>

and (b) bear, whether before or after judgment, interest at the highest rate of
interest provided for overdue payments in any of the Credit Documents commencing
30 days after any such Obligor's receipt of a written notice that such amounts
are due and owing. For the avoidance of doubt, all principal, interest and other
amounts due under any Credit Document shall bear interest, and default interest,
as provided in such Credit Agreement.

      22.   GOVERNING LAW; CONSENT TO JURISDICTION. THIS AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE. Each
Obligor agrees that any action or claim arising out of any dispute in connection
with this Agreement, any rights or obligations hereunder or the performance or
enforcement of such rights or obligations may be brought in the courts of the
State or any federal court sitting therein and consents to the non-exclusive
jurisdiction of such court and to service of process in any such suit being made
upon any Obligor by mail at the address specified in Section 14.4 of the
Intercreditor Agreement. Each Obligor hereby waives any objection that it may
now or hereafter have to the venue of any such suit or any such court or that
such suit is brought in an inconvenient court.

      23.   WAIVER OF JURY TRIAL. EACH OBLIGOR, EACH SECURED PARTY AND THE
COLLATERAL AGENT WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR
CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT, ANY RIGHTS
OR OBLIGATIONS HEREUNDER OR THE PERFORMANCE OR ENFORCEMENT OF ANY SUCH RIGHTS OR
OBLIGATIONS. Except as prohibited by law, each Obligor waives any right which it
may have to claim or recover in any litigation referred to in the preceding
sentence any special, exemplary, punitive or consequential damages or any
damages other than, or in addition to, actual damages. Each Obligor (a)
certifies that neither the Collateral Agent or any Secured Party nor any
representative, agent or attorney of the Collateral Agent or any Secured Party
has represented, expressly or otherwise, that the Collateral Agent or any
Secured Party would not, in the event of litigation, seek to enforce the
foregoing waivers or other waivers contained in this Agreement and (b)
acknowledges that, in entering into each of the Security Documents, the
Collateral Agent and the Secured Parties are relying upon, among other things,
the waivers and certifications contained in this Section 23.

      24.   TERMINATION. Upon either final payment and performance in full of
the Secured Obligations and the cancellation or termination of any commitment to
extend credit under the Credit Documents or satisfaction of the conditions set
forth in Section 14.5 of the Intercreditor Agreement, this Agreement shall
terminate and the Collateral Agent shall, at the Obligors' request and expense,
return such Collateral in the possession or control of the Collateral Agent as
has not theretofore been disposed of pursuant to the provisions hereof, together
with any moneys and other property at the time held by the Collateral Agent
hereunder. Upon

                                       19
<PAGE>

satisfaction of the conditions set forth in Section 14.6 of the Intercreditor
Agreement, this Agreement shall terminate with respect to the Collateral being
released and the Collateral Agent shall, at the Company's request and expense,
return any Collateral held by the Collateral Agent hereunder and take all
necessary action to release the Lien on such Collateral created hereby.

      25.   MISCELLANEOUS. The headings of each section of this Agreement are
for convenience only and shall not define or limit the provisions thereof. This
Agreement and all rights and obligations hereunder shall be binding upon each of
the Obligors and its successors and assigns, and shall inure to the benefit of
the Collateral Agent, the Secured Parties and their respective successors and
assigns. If any term of this Agreement shall be held to be invalid, illegal or
unenforceable, the validity of all other terms hereof shall in no way be
affected thereby, and this Agreement shall be construed and be enforceable as if
such invalid, illegal or unenforceable term had not been included herein. Each
Obligor acknowledges receipt of a copy of this Agreement.

      26.   SUBJECT TO INTERCREDITOR AGREEMENT. Any and all rights granted to
the Collateral Agent under this Agreement are to be held and exercised by the
Collateral Agent as security trustee for the benefit of the Secured Parties
pursuant to the provisions of the Intercreditor Agreement. Each of the Secured
Parties shall be a beneficiary of the terms of this Agreement. Any and all
obligations under this Agreement of the parties to this Agreement, and the
rights and indemnities granted to the Collateral Agent under this Agreement, are
created and granted subject to, and in furtherance (and not in limitation) of,
the terms of the Intercreditor Agreement and the rights and indemnities of the
Secured Parties contained therein shall apply equally to this Agreement. Nothing
in this Agreement expressed or implied is intended or shall be construed to give
to any Person other than the Obligors, the Secured Parties and the Collateral
Agent any legal or equitable right, remedy, or claim under or in respect of this
Agreement or any covenant, condition, or provision herein contained; and all
such covenants, conditions and provisions are and shall be held to be for the
sole and exclusive benefit of the Obligors, the Secured Parties and the
Collateral Agent. Notwithstanding anything herein to the contrary, the
Collateral Agent shall exercise its rights and powers subject to the direction
and indemnity of the Secured Parties as provided in the Intercreditor Agreement.

      Notwithstanding anything to the contrary in this Agreement, in the event
that any term or provision of the Intercreditor Agreement conflicts with any
term or provision of this Agreement, the relevant terms and provisions of the
Intercreditor Agreement shall control concerning such specific term or
provision.

      27.   COURSE OF DEALING. No course of dealing among any one or more of the
Obligors, the Secured Parties and the Collateral Agent, nor any failure to
exercise, nor any delay in exercising, on the part of the Collateral Agent or
any of the Secured Parties, any right, power or privilege hereunder or under the
Security

                                       20
<PAGE>

Agreement 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.
