     with all accrued and unpaid interest, PIK Interest, fees and other amounts
     due hereunder with regard thereto, on November 27, 2006.

     3.3 Optional Prepayment of Notes. Subject to the terms of this Section 3.3,
the Borrowers may prepay to Agent, for the ratable benefit of Purchasers, the
outstanding principal amount of the Notes in whole or in part in multiples of
$100,000, or such lesser amount as is then outstanding, at any time at a price
equal to (i) the accrued interest, if any, to the date set for prepayment, plus
(ii) a prepayment fee representing the amortization of certain of Purchasers'
costs incurred in connection with the purchase of the Term B Notes equal to the
principal amount of the Term B Notes prepaid multiplied by the following
percentage:

             If Prepaid During
             the 12-Month Period
             Ending on November 30
             of the Following Years:                            Percentage
             -----------------------                            ----------

                      2002                                           3%
                      2003                                           2%
                      2004                                           1%

provided, however, that no prepayment fee shall apply to any prepayment of the
outstanding principal amount of the Term B Notes in connection with any
prepayment attributable to Life Insurance proceeds or other insurance proceeds
that are payable to Agent or condemnation awards or payments that are payable to
Agent. No prepayment premium or fee shall apply to any prepayment of the Term A
Notes. All such prepayments shall be applied by Agent first to the

                                       15

<PAGE>

outstanding principal of the Term A Notes and second to the outstanding
principal of the Term B Notes, each in the inverse order of maturity after
application of such prepayment to any accrued interest and prepayment premium
payable in connection therewith.

     3.4 Notice of Optional Prepayment. If any of the Borrowers shall elect to
prepay any Notes pursuant to Section 3.3 hereof, such Borrower shall give notice
of such prepayment to Agent and each holder of the Notes to be prepaid not less
than thirty (30) days or more than ninety (90) days prior to the date fixed for
prepayment, specifying (a) the date on which such prepayment is to be made, (b)
the principal amount of such Notes to be prepaid on such date, and (c) the
premium, if any, and accrued interest applicable to the prepayment. Such notice
shall be accompanied by a certificate of the president of such Borrower that
such prepayment is being made in compliance with Section 3.3. Notice of
prepayment having been so given, the aggregate principal amount of the Notes
specified in such notice, together with accrued interest thereon and the
premium, if any, shall become due and payable on the prepayment date set forth
in such notice.

     3.5 Mandatory Prepayment.

         (a) The Notes shall be prepaid in full, together with all
     interest, fees and expenses plus a prepayment premium on the Term B
     Notes computed in accordance with Section 3.3, as if such prepayment
     were a voluntary prepayment, in the event of (i) a Change of Control or
     (ii) a default under the Indenture that would entitle the holder of
     such Indebtedness to accelerate the maturity of such Indebtedness or
     could reasonably be expected to have a Material Adverse Effect.

         (b) Within ten (10) days of the completion of the quarterly
     financial statements on Form 10-Q or Form 10-K for each fiscal quarter,
     the Borrowers shall prepay the respective Term A Notes, on a pro rata
     basis, in a total amount equal to twenty-five percent (25.0%) of Excess
     Cash Flow measured from January 1 of the then current fiscal year
     through the end of the most recent fiscal quarter then ended, less the
     total of all prepayments made under this Section 3.5(b) for previous
     quarters of the same fiscal year (but not less than zero) which shall
     be applied to the outstanding principal installments of the Term A
     Notes on a pro rata basis in accordance with the respective principal
     amounts outstanding at the end of the most recently ended fiscal
     quarter in the inverse order of maturity. In the event that the
     financial statements are not so delivered within fifty-five (55) days
     of the fiscal quarter end for the first three (3) quarters of any
     applicable fiscal year or within one hundred (100) days of year end,
     then a calculation based upon estimated amounts shall be made by Agent
     upon which calculation the Company shall make the prepayment required
     by this Section 3.5(b) within ten (10) days of receipt of such
     calculation, subject to adjustment when such financial statements are
     delivered to Agent as required hereby. The calculation made by Agent
     shall not be deemed a waiver of any rights Agent or Purchasers may have
     as a result of the failure by the Loan Parties to deliver such
     financial statements.

     3.6 Home Office Payment. The Borrowers will pay all sums becoming due on
such Notes for principal, premium, if any, and interest to Agent by the method
and at the address specified for such purpose in Annex A, or by such other
method or at such other address as Purchasers shall have from time to time
specified to the Borrowers in writing for such purpose, without the presentation
or surrender of such Notes or the making of any notation thereon, except that
upon written request of the Borrowers made concurrently with or reasonably
promptly after

                                       16

<PAGE>

payment or prepayment in full of any Note, each holder of a Note shall surrender
such Note for cancellation, reasonably promptly after such request, to the
Company at its principal executive office.

     3.7 Taxes. Any and all payments by the Loan Parties hereunder or under the
Notes or other Purchase Documents that are made to or for the benefit of
Purchasers shall be made free and clear of and without deduction for any and all
present or future taxes, levies, imposts, deductions, charges or withholdings
and penalties, interests and all other liabilities with respect thereto
(collectively, "Taxes"), excluding taxes imposed on Agent's or Purchasers' net
income, value added taxes, business occupation taxes, or other taxes on the
privilege of doing business in a given jurisdiction, or capital and franchise
taxes imposed on any of them by the jurisdiction under the laws of which any of
them is organized or any political subdivision thereof (all such nonexcluded
Taxes being hereinafter referred to as "Covered Taxes"). If any of the Loan
Parties shall be required by law to deduct any Covered Taxes from or in respect
of any sum payable hereunder or under any Notes or other Purchase Documents to
Agent for the benefit of Purchasers, or to Purchasers, the sum payable shall be
increased as may be necessary so that after making all required deductions of
Covered Taxes (including deductions of Covered Taxes applicable to additional
sums payable under this paragraph), each Purchaser receives an amount equal to
the sum it would have received had no such deductions been made. The Loan
Parties shall make such deductions and the Loan Parties shall pay the full
amount so deducted to the relevant taxation authority or other authority in
accordance with applicable law. In addition, the Loan Parties agree to pay any
present or future stamp, documentary, excise, privilege, intangible or similar
levies that arise at any time or from time to time from any payment made under
any and all Purchase Documents or from the execution or delivery by the Loan
Parties or from the filing or recording or maintenance of, or otherwise with
respect to the exercise by Agent or Purchasers of their respective rights under
any and all Purchase Documents (collectively, "Other Taxes"). The Loan Parties
will indemnify Agent and Purchasers for the full amount of Covered Taxes imposed
on or with respect to amounts payable hereunder and Other Taxes, and any
liability (including penalties, interest and expenses) arising therefrom or with
respect thereto. Payment of this indemnification shall be made within thirty
(30) days from the date Agent or Purchasers provide the Loan Parties with a
certificate certifying and setting forth in reasonable detail the calculation
thereof as to the amount and type of such Taxes. Any such certificates submitted
by Agent or Purchasers in good faith to the Loan Parties shall, absent manifest
error, be final, conclusive and binding on all parties. The obligation of the
Loan Parties under this Section 3.7 shall survive the payment of the Notes and
the termination of this Agreement. Within thirty (30) days after the Loan
Parties having received a receipt for payment of Covered Taxes and/or Other
Taxes, the Loan Parties shall furnish to Agent, the original or certified copy
of a receipt evidencing payment thereof.

     3.8 Maximum Lawful Rate. This Agreement, the Notes and the other Purchase
Documents are hereby limited by this Section 3.8. In no event, whether by reason
of acceleration of the maturity of the amounts due hereunder or otherwise, shall
interest and fees contracted for, charged, received, paid or agreed to be paid
to Purchasers exceed the maximum amount permissible under applicable law. If,
from any circumstance whatsoever, interest and fees would otherwise be payable
to Agent or Purchasers in excess of the maximum amount permissible under
applicable law, the interest and fees shall be reduced to the maximum amount
permitted under applicable law. If from any circumstance, Agent or Purchasers
shall have received anything of

                                       17

<PAGE>

value deemed interest by applicable law in excess of the maximum lawful amount,
an amount equal to any excess of interest shall be applied to the reduction of
the principal amount of the Notes, in such manner as may be determined by
Purchasers, and not to the payment of fees or interest, or if such excessive
interest exceeds the unpaid balance of the principal amount of the Notes, such
excess shall be refunded to the Loan Parties. To the extent that any payment or
demand under any Purchase Document is determined to be contrary to the Criminal
Code (Canada) or other applicable law, such payment or demand shall be deemed to
have been made by mutual mistake of the Loan Parties, Agent and Purchasers. The
Loan Parties shall not have any action against the Agent or the Purchaser for
any damages whatsoever arising out of the payment or collection of any amounts
in excess of the amounts permitted by the Criminal Code (Canada) or other
applicable law.

     3.9 Capital Adequacy. If, after the date hereof, either the introduction of
or any change of the interpretation of any law or the compliance by Purchasers
with any guideline or request from any governmental authority (whether or not
having the force of law) has or would have the effect of reducing the rate of
return on the capital or assets of Purchasers as a consequence of, as determined
by Agent or Purchasers in their sole discretion, the existence of any
Purchaser's obligations under this Agreement or any other Purchase Documents,
then, upon demand by Purchasers, the Loan Parties immediately shall pay to
Purchasers, from the time as specified by Purchasers, additional amounts
sufficient to compensate Purchaser in light of such circumstances. The
obligations of the Loan Parties under this Section 3.9 shall survive the
payments of the Notes and the termination of this Agreement.

     3.10 Certain Waivers. The Loan Parties unconditionally waive (a) any rights
to presentment, demand, protest or (except as expressly required hereby) notice
of any kind, and (b) any rights of rescission, setoff, counterclaim or defense
to payment under the Notes or otherwise that the Loan Parties may have or claim
against any Purchaser, the Agent or any prior Purchaser or Agent.

                                TRANSFER OF NOTES

     6.1 Restricted Notes. Purchasers acknowledge that the Notes have not been
registered under the Securities Act or the securities laws of any other
applicable jurisdiction and may be resold only if registered pursuant to the
provisions of the Securities Act or the securities laws of any other applicable
jurisdiction or if an exemption from registration is available, and that the
Company is not required to register the Notes.

     6.2 Legends; Purchaser's Representations. Each of Purchasers hereby
represents and warrants to the Company that it is an "accredited investor"
within the meaning of Rule 501(a)

account, with no present intention of dividing its participation with others
(except for a potential transfer or transfers of the Notes to an affiliate or
affiliates of Purchasers) or reselling or otherwise distributing the same in
violation of the Securities Act or any applicable domestic or foreign securities
laws. The Borrowers may place an appropriate legend on the Notes owned by
Purchasers concerning the restrictions set forth in this Article 6. Upon the
assignment or transfer by Purchasers or any of its successors or assignees of
all or any part of the Notes, the term "Purchaser" as used herein shall
thereafter mean, to the extent thereof, the then holder or holders of such
Notes, or portion thereof.

     6.3 Transfer of Notes. Subject to Section 6.2 hereof, a holder of a Note
may transfer such Note to a new holder or may exchange such Note for Notes of
different denominations (but in no event of denominations of less than $100,000
in original principal amount), by surrendering such Note to the applicable
Borrower duly endorsed for transfer or accompanied by a duly executed instrument
of transfer naming the new holder (or the current holder if submitted for
exchange only), together with written instructions for the issuance of one or
more new Notes specifying the respective principal amounts of each new Note and
the name of each new holder and each address therefor. Such Borrower shall
simultaneously deliver to such holder or its designee such new Notes, shall mark
the surrendered Notes as canceled and shall provide notice of such transfer to
Agent. In lieu of the foregoing procedures, a holder may assign a Note (in whole
but not in part) to a new holder by sending written notice to the applicable
Borrower and Agent of such assignment specifying the new holder's name and
address; in such case, the Company shall promptly acknowledge such assignment in
writing to both the old and new holder. No Borrower shall be required to
recognize any subsequent holder of a Note unless and until such Borrower has
received reasonable assurance that all applicable transfer taxes have been paid.

     6.4 Replacement of Lost Notes. Upon receipt of evidence reasonably
satisfactory to the applicable Borrower of the mutilation, destruction, loss or
theft of any Notes and the ownership thereof, such Borrower shall, upon the
written request of the holder of such Notes, execute and deliver in replacement
thereof new Notes in the same form, in the same original principal amount and
dated the same date as the Notes so mutilated, destroyed, lost or stolen; and
such Notes so mutilated, destroyed, lost or stolen shall then be deemed no
longer outstanding hereunder. If the Notes being replaced have been mutilated,
they shall be surrendered to the applicable Borrower; and if such replaced Notes
have been destroyed, lost or stolen, such holder shall furnish such Borrower
with an indemnity in writing to save it harmless in respect of such replaced
Note.

     6.5 No Other Representations Affected. Nothing contained in this Article 6
shall limit the full force or effect of any representation, agreement or
warranty made herein or in connection herewith to Purchaser.

     public accountants.

          (i) Board of Directors.

               (i) The Company's Board of Directors shall consist of no more
          than six (6) directors during any time no Material Event Default
          exists and so long as the principal balance of the Notes or any
          portion thereof has not been accelerated, and shall meet at least once
          per calendar quarter for so long as any Purchaser shall hold any Note.
          Purchasers shall have the right to designate one member to the
          Company's Board of Directors and, if any of boards of director of the
          other Loan Parties deal with matters outside the day-to-day operation
          of such Loan Party, purchasers shall have the right to designate one

          the Company cures the condition giving rise to the events listed in
          (A) and (B) above and subsequently those conditions again cause the
          events listed in (A) or (B) above to be true, the Purchasers' right to
          appoint a majority of the Board of Directors shall become permanent.
          Members of each Board of Directors designated by Purchasers shall
          receive reimbursement for reasonable out-of-pocket expenses from the
          Loan Parties incurred in connection with attendance at Boards of
          Directors, committee and stockholder meetings. The Company shall
          reserve and keep vacant a number of board seats sufficient for
          Purchasers to appoint a majority of the Board of Directors of the
          Company. John H. Welker shall vote all shares of the Loan Parties in
          which he has voting control in a manner that will give effect to the
          rights of Purchasers pursuant to this Section 7.1(i).

               (ii) In the event Purchasers shall waive their right to designate
          a Director pursuant to this Section 7.1(i), Agent may designate an
          observer, without voting rights, who will be entitled to attend all
          meetings of the Loan Parties' Boards of Directors (including
          committees) and stockholders. Any observer designated by Purchasers'
          shall be entitled to notice of all meetings of the Loan Parties'
          Boards of Directors (including committee meetings) and to information
          provided to Directors. Such observer shall receive reimbursement for
          reasonable out-of-pocket expenses from the Loan Parties incurred in
          connection with attendance at Boards of Directors, committee and
          stockholder meetings.

               (iii) The Board of Directors of the Company shall maintain audit
          and compensation committees. Purchasers shall have the right to
          designate one director to each of the audit and compensation
          committees so long as any Note shall remain outstanding.

               (iv) All rights of Purchasers under this Section 7.1(i) shall be
          exercised by Required Purchasers.

          (j) Future Financings. The Loan Parties shall give to Agent and
     Purchasers an opportunity to participate in any future financings of the
     Loan Parties.

          (k) Collateral Monitoring Fee. On the first day of each month after
     Closing, the Company shall pay to Agent a collateral monitoring fee in an
     amount equal to $14,583.

          (l) Additional Security. The Loan Parties shall execute and deliver
     additional Security Documents within 30 days after request therefor by the
     Agent, sufficient to grant to the Agent for the benefit of the Purchasers
     Liens in any after-acquired property including, without limitation,
     machinery and equipment (but no more than 66% of the capital stock of any
     Foreign Subsidiary). Each Loan Party shall notify Agent within ten (10)
     days after the occurrence thereof, of the acquisition of any property that
     is not subject to any of the existing Security Documents (but no more than
     66% of the capital stock of any Foreign Subsidiary). Upon the occurrence
     and during the continuation of an Event of Default, the Company shall, upon
     request of the Agent, deliver to Agent for the benefit of the Purchasers
     100% of the capital stock of Numatics Canada and Numatics GmbH.

          (l) a Change of Control shall have occurred; and

          (m) a requirement from the Minister of National Revenue for payment

     the holders thereof hereunder and thereunder shall be immediately due and
     payable, without presentment, demand, protest or (except as expressly
     required hereby) notice of any kind, all of which are hereby expressly
     waived.

          (b) Other Defaults. If any other Event of Default shall occur,
     Required Purchasers may at their option, by written notice to the Loan
     Parties, declare the entire unpaid balance of the Notes, and interest
     accrued thereon and all other liabilities of the Loan Parties hereunder and
     thereunder to be forthwith due and payable, and the same shall thereupon
     become immediately due and payable, without presentment, demand, protest or
     (except as expressly required hereby) notice of any kind, all of which are
     hereby expressly waived; provided, that in the case of a default specified
     in clause (ii) of paragraph (a) of Section 8.1 hereof shall occur, any
     holder of a Note may declare the entire unpaid balance of such Note (but
     only such Note) and other amounts due hereunder and thereunder with regard

          (c) Penalty Interest. Following the occurrence and during the
     continuance of any Event of Default, the holders of the Notes, at the
     election of the Required Purchasers, shall be entitled to receive, to the

          (e) Appointment of Receiver. With respect to Collateral located in
     Canada or any other Collateral of Numatics Canada, the Agent and Purchasers
     may appoint, remove and reappoint any person or persons, including any

     "Receiver") which term shall include a receiver and manager of, or agent
     for, all or any part of the Collateral located in Canada or any other
     Collateral of Numatics Canada. Any such Receiver shall, as far as concerns
     responsibility for his acts, be deemed to be the agent of the Loan Parties
     and not of the Agent or any Purchaser, and the Agent and the Purchasers
     shall not in any way be responsible for any misconduct, negligence or
     non-feasance of such Receiver, its employees or agents. Except as otherwise
     directed by the Agent and the Purchasers, all money received by such
     Receiver shall be received in trust for and paid to Agent for the benefit
     of the Purchasers. Such Receiver shall have all of the powers and rights of
     the Agent and the Purchasers described in Section 8.2. The Agent may,
     either directly or through its agents or nominees, exercise any or all
     powers and right of a Receiver.

                                   ARTICLE 9

                                    THE AGENT

     9.1 Authorization and Action. Each Purchaser and each subsequent holder of
any Note by its acceptance thereof, hereby designates and appoints ACFS as Agent
hereunder and authorizes ACFS to take such actions as agent on its behalf and to
exercise such powers as are delegated to Agent by the terms of this Agreement
and the other Purchase Documents, together with such powers as are reasonably
incidental thereto. Agent shall not have any duties or responsibilities, except
those expressly set forth herein, or any fiduciary relationship with any
Purchaser, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities on the part of Agent shall be read into this
Agreement or otherwise exist for Agent. In performing its functions and duties
hereunder, Agent shall act solely as agent for Purchasers and does not assume,
nor shall be deemed to have assumed, any obligation or relationship of trust or
agency with or for the Loan Parties or any of their respective successors or
assigns. Agent shall not be required to take any action that exposes Agent to
personal liability or that is contrary to this Agreement or applicable Laws. The
appointment and authority of Agent hereunder shall terminate at the indefeasible
payment in full of the Notes and related obligations.

     9.2 Delegation of Duties. Agent may execute any of its duties under this
Agreement by or through agents or attorneys-in-fact and shall be entitled to
advice of counsel concerning all matters pertaining to such duties. Agent shall
not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

     9.3 Exculpatory Provisions. Neither Agent nor any of its directors,
officers, agents or employees shall be (a) liable for any action lawfully taken
or omitted to be taken by it or them under or in connection with this Agreement
(except for its, their or such Person's own gross

                                       47

<PAGE>

negligence or willful misconduct or, in the case of Agent, the breach of its
obligations expressly set forth in this Agreement, unless such action was taken
or omitted to be taken by Agent at the direction of the Required Purchasers), or
(b) responsible in any manner to any of Purchasers for any recitals, statements,
representations or warranties made by the Loan Parties contained in this
Agreement or in any certificate, report, statement or other document referred to
or provided for in, or received under or in connection with, this Agreement for
the value, validity, effectiveness, genuineness, enforceability or sufficiency
of this Agreement or any other document furnished in connection herewith, or for
any failure of any of the Loan Parties to perform their respective obligations
hereunder, or for the satisfaction of any condition specified in Article 4.
Agent shall not be under any obligation to any Purchaser to ascertain or to
inquire as to the observance or performance of any of the agreements or
covenants contained in, or conditions of, this Agreement, or to inspect the
properties, books or records of any of the Loan Parties.

     9.4 Reliance. Agent shall in all cases be entitled to rely, and shall be
fully protected in relying, upon any document or conversation believed by it to
be genuine and correct and to have been signed, sent or made by the proper
Person or Persons and upon advice and statements of legal counsel (including,
without limitation, counsel to the Loan Parties), independent accountants and
other experts selected by Agent. Agent shall in all cases be fully justified in
failing or refusing to take any action under this Agreement or any other
document furnished in connection herewith unless it shall first receive such
advice or concurrence of the Required Purchasers or all of Purchasers, as
applicable, as it deems appropriate or it shall first be indemnified to its
satisfaction by Purchasers; provided, that, unless and until Agent shall have
received such advice, Agent may take or refrain from taking any action, as Agent
shall deem advisable and in the best interests of Purchasers. Agent shall in all
cases be fully protected in acting, or in refraining from acting, in accordance
with a request of the Required Purchasers or all of Purchasers, as applicable,
and such request and any action taken or failure to act pursuant thereto shall
be binding upon all Purchasers.

     9.5 Non-Reliance on Agent and Other Purchasers. Each Purchaser expressly
acknowledges that neither Agent, nor any of its officers, directors, employees,
agents, attorneys-in-fact or affiliates has made any representations or
warranties to it and that no act by Agent or hereafter taken, including, without
limitation, any review of the affairs of the Loan Parties, shall be deemed to
constitute any representation or warranty by Agent. Each Purchaser represents
and warrants to Agent that it has and will, independently and without reliance
upon Agent or any other Purchaser and based on such documents and information as
it has deemed appropriate, made its own appraisal of and investigation into the
business, operations, property, prospects, financial and other conditions and
creditworthiness of the Loan Parties and made its own decision to enter into
this Agreement.

     9.6 Agent in its Individual Capacity. Agent, and each of its Affiliates may
make loans to, purchase securities from, provide services to, accept deposits
from and generally engage in any kind of business with the Loan Parties or any
Affiliate of the Loan Parties as though Agent were not Agent hereunder.

     9.7 Successor Agent. Agent may, upon forty-five (45) days' notice to the
Loan Parties and Purchaser, and Agent will, upon the direction of the Required
Purchasers (other than Agent,

                                       48

<PAGE>

in its individual capacity), resign as Agent. If Agent shall resign, then the
Required Purchasers during such fifteen-day period shall appoint a successor
Agent and if the Required Purchasers direct Agent to resign, such direction
shall include an appointment of a successor Agent. If for any reason no
successor Agent is appointed by the Required Purchasers during such fifteen-day
period, then effective upon the expiration of such fifteen-day period, the
resigning Agent shall appoint a successor Agent among the remaining Purchasers.
After any retiring Agent's resignation hereunder as Agent, the provisions of
Article 9 shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Agent under this Agreement.

     9.8 Collections and Disbursements.

          (a) Agent will have the right to collect and receive all payments of
     the Notes, and to collect and receive all reimbursements due hereunder,
     together with all fees, charges or other amounts due under this Agreement
     and the other Purchase Documents with regard to the Notes, and Agent will
     remit to each Purchaser, according to its pro rata percentage, all such
     payments actually received by Agent in accordance with the settlement
     procedures established from time to time. Settlements shall occur on such
     dates as Agent may elect in its sole discretion, but which shall be no
     later than two (2) Business Days following receipt thereof.

          (b) If any such payment received by Agent is rescinded or otherwise
     required to be returned for any reason at any time, whether before or after
     termination of this Agreement or the other Purchase Documents, each
     Purchaser will, upon written notice from Agent, promptly pay over to Agent
     its pro rata percentage of the amounts so rescinded or returned, together
     with interest and other fees thereon so rescinded or returned.

          (c) All payments by Agent and Purchasers to each other hereunder shall
     be in immediately available funds. Agent will at all times maintain proper
     books of accounts and records reflecting the interest of each Purchaser in
     the Notes, in a manner customary to Agent's keeping of such records, which
     books and records shall be available for inspection by each Purchaser at
     reasonable times during normal business hours, at such Purchaser's sole
     expense. Agent may treat the payees of any Note as the holder thereof until
     written notice of the transfer thereof shall have been received by Agent in
     accordance with Section 6.3. In the event that any Purchaser shall receive
     any payment in reduction of the Notes in an amount greater than its
     applicable pro rata percentage in respect of obligations to Purchaser
     evidenced hereby (including, without limitation amounts obtained by reason
     of setoffs) such Purchaser shall hold such excess in trust for Agent (on
     behalf of all other Purchasers) and shall promptly remit to Agent such
     excess amount so that the amounts received by each Purchaser hereunder
     shall at all times be in accordance with its applicable pro rata
     percentage. If, however, any Purchaser that has received any such excess
     amount fails to remit such amount to the Agent, the Agent shall reallocate
     the amounts paid on the next payment date to each Purchaser so that, after
     giving effect to such payments, the pro rata obligations owed by the Loan
     Parties to each Purchaser shall be in an amount equal to the pro rata
     amount owed by the Loan Parties before the date of the payment of such
     excess amount. In no event shall any Purchaser be

                                       49

<PAGE>

     deemed to have a participation or other right in, to or against any other
     Purchaser's Note as a result of the payment of any excess amount.

     9.9 Reporting. During the term of this Agreement, Agent will promptly
furnish each Purchaser with copies of all notices and financial statements of
the Loan Parties required to be delivered or obtained hereunder and such other
financial statements and reports and other information in Agent's possession as
any Purchaser may reasonably request. Agent will immediately notify Purchasers
when it receives actual knowledge of any Event of Default under the Purchase
Documents.

     9.10 Consent of Purchasers.

          (a) Except as expressly provided herein, Agent shall have the sole and
     exclusive right to service, administer and monitor the Notes and the
     Purchase Documents related thereto, including, without limitation, the
     right to exercise all rights, remedies, privileges and options under this
     Agreement and under the other Purchase Documents, including, without
     limitation, the credit judgment with respect to the purchasing of the Notes
     and the determination as to the basis on which and extent to which
     purchases of Notes may be made.

          (b) Notwithstanding anything to the contrary contained in Section
     9.10(a) above, Agent shall not without the prior written consent of all
     Purchasers then holding Notes: (i) extend any payment date under the Notes,
     (ii) reduce any interest rate applicable to any of the Notes or any fee
     payable to Purchasers hereunder, (iii) waive any Event of Default under
     Section 8.1 (a), (iv) compromise or settle all or a portion of the
     Indebtedness under the Notes, (v) release any obligor from the Indebtedness
     under the Notes except in connection with full payment and satisfaction of
     all Indebtedness under the Notes, (vi) amend the definition of Required
     Purchasers, or (vii) amend this Section 9.10(b).

          (c) Notwithstanding anything to the contrary contained in Section
     9.10(a) above, and subject to any applicable limitation set forth in
     Section 9.10(b) above, Agent shall not, without the prior written consent
     of Required Purchasers: (i) waive any Event of Default; (ii) consent to any
     Loan Party's taking any action that, if taken, would constitute an Event of
     Default under this Agreement or under any of the other Purchase Documents;
     or (iii) amend or modify or agree to an amendment or modification of this
     Agreement or other Purchase Documents.

          (d) After an acceleration of the Indebtedness, Agent shall have the
     sole and exclusive right, after consultation (to the extent reasonably
     practicable under the circumstances) with all Purchasers and, unless
     otherwise directed in writing by Required Purchasers, to exercise or
     refrain from exercising any and all rights, remedies, privileges and
     options under this Agreement or the other Purchase Documents and available
     at law or in equity to protect the rights of Agent and Purchaser and
     collect the Indebtedness under the Notes, including, without limitation,
     instituting and pursuing all legal actions brought against any Loan Party
     or to collect the Indebtedness under the Notes, or defending any and all
     actions brought by any Loan Party or other Person; or incurring

                                       50

<PAGE>

     expenses or otherwise making expenditures to protect the collateral, the
     Notes or Agent's or any Purchaser's rights or remedies.

     9.11 This Article Not Applicable to Loan Parties. This Article 9 is
included in this Agreement solely for the purpose of determining certain rights
as between Agent and Purchasers and does not create, nor shall it give rise to,
any rights in or obligations on the part of the Loan Parties and all rights and
obligations of the Loan Parties (other than as specifically set forth herein)
under this Agreement shall be determined by reference to the provisions of this
Agreement other than this Article 9.

remedy. The rights and remedies hereunder are cumulative and not exclusive of

RELATED TO THIS AGREEMENT AND AGREES THAT ANY SUCH ACTION OR COUNTERCLAIM SHALL
BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

     11.11 Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law in any jurisdiction, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without
invalidating any other provision of this Agreement.

     11.12 Headings. Article, section and subsection headings in this Agreement
are included for convenience of reference only and shall not constitute a part
of this Agreement for any other purpose.

     11.13 Indemnity. The Loan Parties hereby agree to indemnify, defend and
hold harmless Agent and Purchasers and their officers, directors, employees,
agents and representatives, and their respective successors and assigns in
connection with any losses, claims, damages, liabilities and expenses, including
reasonable legal fees, to which Agent or any Purchaser may become subject (other
than as a result of the gross negligence or willful misconduct of any such
Person), insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or by reason of any investigation, litigation or
other proceedings related to or resulting from any act of, or omission by, the
Loan Parties or their Affiliates or any officer, director, employee, agent or
representative of the Loan Parties or their Affiliates with respect to the
Transactions, the Notes, Charter Documents, the Bylaws or any agreements entered
into in connection with any such agreements, instruments or documents and to
reimburse Agent and Purchasers and each such Person and Affiliate, upon demand,
for any legal or other expenses incurred in connection with investigating or
defending any such loss, claim, damage, liability, expense or action. To the
extent that the foregoing undertakings may be unenforceable for any reason, the
Loan Parties agree to make the maximum contribution to the payment and
satisfaction of indemnified liabilities set forth in this Section 11.13 which is
permissible under applicable law.

     11.14 Environmental Indemnity. The Loan Parties, and their successors and
assigns, hereby release and discharge, and agree to defend, indemnify and hold
harmless, Agent, Purchasers and their Affiliates (including their partners,
subsidiaries, customers, guests, and invitees, and the successors and assigns of
all of the foregoing, and their respective officers, employees and agents) from
and against any and all Environmental Liabilities, whenever and by whomever
asserted, to the extent that such Environmental Liabilities are based upon, or
otherwise relate to: (i) any Condition at any time in, at, on, under, a part of,
involving or otherwise related to the Properties and Facilities (including any
of the properties, materials, articles, products, or other things included in or
otherwise a part of the Properties and Facilities); (ii) any action or failure
to act of any Person, including any prior owner or operator of the Properties
and Facilities (including any of the properties, materials, articles, products,
or other things included in or otherwise a part of the Properties and
Facilities), involving or otherwise related to the Properties and Facilities or
operations of the Loan Parties; (iii) the Management of any Pollutant, material,
article or product (including Management of any material, article or product
containing a Pollutant) in any physical state and at any time, involving or
otherwise related to the Properties and Facilities or any property covered by
clause (iv) (including Management either from the Properties and Facilities or
from any property covered by clause (iv), and Management to, at,

involving or otherwise related to the Properties and Facilities or any property
covered by clause (iv)); (iv) Conditions, and actions or failures to act, in,
at, on, under, a part of, involving or otherwise related to any property other
than the Properties and Facilities, which property was, at or prior to the
Closing Date, (I) acquired, held, sold, owned, operated, leased, managed, or
divested by, or otherwise associated with, (A) the Loan Parties, (B) any of the
Loan Parties' Affiliates, or (C) any predecessor or successor organization of
those identified in (A) or (B); or (II) engaged in any tolling, contract
manufacturing or processing, or other similar activities for, with, or on behalf
of the Loan Parties; (v) any violation of or noncompliance with or the assertion
of any Lien under the Environmental Laws, (vi) the presence of any toxic or
hazardous substances, wastes or contaminants on, at or from the past and present
Properties and Facilities, including, without limitation, human exposure
thereto; (vii) any spill, release, discharge or emission affecting the past and
present Properties and Facilities, whether or not the same originates or
emanates from such Properties and Facilities or any contiguous real estate,
including, without limitation, any loss of value of such Properties and
Facilities as a result thereof; or (viii) a misrepresentation in any
representation or warranty or breach of or failure to perform any covenant made
by the Loan Parties in this Agreement. This indemnity and agreement to defend
and hold harmless shall survive any termination or satisfaction of the Notes or
the sale, assignment or foreclosure thereof or the sale, transfer or conveyance
of all or part of the past and present properties and facilities or any other
circumstances which might otherwise constitute a legal or equitable release or
discharge, in whole or in part, of the Loan Parties under the Notes.

     11.15 Counterparts. This Agreement may be executed in any number of
counterparts and by either party hereto on separate counterparts, each of which,
when so executed and delivered, shall be an original, but all such counterparts
shall together constitute one and the same instrument.

     11.16 Integration. This Agreement and the other Purchase Documents set
forth the entire understanding of the parties hereto with respect to all matters
contemplated hereby and supersede all previous agreements and understandings
among them concerning such matters. No statements or agreements, oral or
written, made prior to or at the signing hereof, shall vary, waive or modify the
written terms hereof.

     11.17 Confidentiality. Each Loan Party, Agent and each Purchaser hereby
agree and acknowledge that any and all information relating to such Loan Party
which is (i) furnished by such Loan Party to Agent or such Purchaser (or to any
affiliate of such Purchaser); and (ii) non-public, confidential or proprietary
in nature, shall be kept confidential by Agent or such Purchaser or such
affiliate in accordance with applicable law; provided, however, that such
information and other credit information relating to such Loan Party may be
distributed by Agent or such Purchaser or such affiliate to Agent's or such
Purchaser's or such affiliate's directors, officers, employees, attorneys,
affiliates, assignees, participants (provided such assignees and/or participants
have agreed to keep such information confidential to the extent provided in this
Section 11.17) auditors, agents and regulators, and upon the order of a court or
other governmental agency having jurisdiction over such Purchaser or such
affiliate, to any other party. Each Loan Party, Agent and each Purchaser further
agree that this provision shall survive the termination of this Agreement.
Notwithstanding the foregoing, each Loan Party hereby consents

                                       57

to Agent publishing a tombstone or similar advertising material relating to the
financing transaction contemplated by this Agreement.

     11.18 Judgment Currency. To the extent permitted by applicable laws, the
obligations of the Loan Parties in respect of any amount due under this
Agreement or any other Purchase Document shall, notwithstanding any payment in
any other currency (the "Other Currency") (whether pursuant to a judgment or
otherwise), be discharged only to the extent of the amount in the currency in
which it is due (the "Agreed Currency") that the Agent or any Purchaser may, in
accordance with normal banking procedures, purchase with the sum paid in the
Other Currency (after any premium and costs of exchange) on the Business Day
immediately after the day on which the Agent or such Purchaser receives the
payment. If the amount in the Agreed Currency that may be so purchased for any
reason falls short of the amount originally due, the applicable Loan Party shall
pay additional amounts, in the Agreed Currency, as may be necessary to
compensate for the shortfall. Any obligation of the applicable Loan Party not
discharged by that payment shall, to the extent permitted by applicable law, be
due as a separate and independent obligation and, until discharged as provided
in this Section 11.18 continue in full force and effect.
