ITEM 1.  CHANGES IN CONTROL OF REGISTRANT.

         On February 2, 2000, Heat Merger Corp., a wholly-owned subsidiary of
Heat Holdings Corp., merged with Aavid Thermal Technologies, Inc. (the
"Company"), with the Company as the surviving corporation and a wholly-owned
subsidiary of Heat Holdings Corp. (the "Merger"). Heat Holdings Corp. and Heat
Merger Corp. were formed by Willis Stein & Partners II, L.P. and certain
co-investors to acquire the Company. In the merger, each outstanding share of
the Company's Common Stock was converted into the right to receive $25.50 in
cash without interest, and all outstanding options and warrants were canceled in
exchange for a cash payment equal to the difference, if any, between $25.50 and
the exercise price. The purchase price for the Company was funded through:

                  - equity contributions from Heat Holdings Corp. and its
         affiliate, Heat Holdings II Corp., of $152.0 million;
                  - net proceeds (after original issue discount and underwriting
         discounts and commissions, but before expenses) of $143.9 million from
         the issuance of 150,000 Units (the "Units"), consisting of (i) an
         aggregate of $150 million principal amount of the Company's 12.75%
         Senior Subordinated Notes due 2007 (the "Notes"), which Notes are
         guaranteed by the Company's domestic subsidiaries, and (ii) warrants to
         purchase an aggregate of 60 shares of the Company's Class A Common
         Stock and warrants to purchase an aggregate of 60 shares of the
         Company's Class H Common Stock (the "Warrants");
                  - $54.7 million of borrowings under the Company's amended and
         restated credit facility; and
                  - cash on hand.

         In connection with the Merger, the Company consummated the sale of
the Units. The sale of the Units, consisting of the Notes and the Warrants,
was made through a Rule 144A offering to qualified institutional buyers. The
Indenture provides that upon a change in control of the Company, the Company
must offer to repurchase the Notes at 101% of the face value thereof,
together with accrued and unpaid interest. The Notes are subordinated in
right of payment to amounts outstanding under the Credit Facility (as defined
below) and certain other permitted indebtedness. Pursuant to a registration
rights agreement, the Company has agreed to file a registration statement to
exchange the Notes for substantially identical notes which have been
registered under the Securities Act of 1933. In addition, the Company has
agreed to register the shares of the Company's Class A Common Stock and Class
H Common Stock underlying the Warrants on a piggyback basis under certain
circumstances. The Units, Notes and Warrants have not been registered under
the Securities Act of 1933, as amended, and may not be offered and sold in
the United States absent registration under such Act or an applicable
exemption from registration.

         In addition, in connection with the Merger the Company entered into an
amended and restated revolving credit and term loan facility with Canadian
Imperial Bank of Commerce, as Administrative Agent, and certain other lenders
(the "Credit Facility"). The Credit Facility, which


                                       -2-

<PAGE>



replaced its existing $100 million revolving credit and term loan facility,
consists of a $53 million term loan facility (the "Term Facility") and a $22
million revolving credit facility, including a $2 million letter of credit
subfacility (the "Revolving Facility"). The Term Facility, all of which was
borrowed on February 2, 2000 to repay amounts outstanding under its existing
credit facility, matures on March 31, 2005, and will be amortized in 18
consecutive quarterly installments, commencing December 31, 2000, as follows:
five quarterly payments of $2 million each; four quarterly payments of $2.5
million each; four quarterly payments of $2.75 million each; two quarterly
payments of $3.2 million each; two quarterly payments of $3.9 million; and a
final payment of $7.8 million. The Revolving Facility matures on March 31, 2005.
The Credit Facility bears interest at a rate equal to, at the Company's option,
either (1) in the case of Eurodollar loans, the sum of (x) the interest rate in
the London interbank market for loans in an amount substantially equal to the
amount of borrowing and for the period of borrowing selected by the Company and
(y) a margin of between one and one-half percent and two and one-quarter percent
(depending on the Company's consolidated leverage ratio (as defined in the
credit agreement)) or (2) the sum of (A) the higher of (x) Canadian Imperial
Bank of Commerce's prime or base rate or (y) one-half percent plus the latest
overnight federal funds rate plus (y) a margin of between one quarter percent
and one percent (depending on the Company's consolidated leverage ratio). The
Credit Facility may be prepaid at any time in whole or in part without penalty,
and must be prepaid to the extent of certain equity or asset sales and excess
cash flow.

         The Credit Facility and the indenture pursuant to which the Notes were
issued limit the Company's ability to incur debt, to sell or dispose of assets,
to create or incur liens, to make additional acquisitions, to pay dividends, to
purchase or redeem its stock and to merge or consolidate with any other person.
In addition, the Credit Facility requires that the Company meet certain
financial ratios, and provides the banks with the right to require the payment
of all amounts outstanding under the facility, and to terminate all commitments
thereunder, if there is a change in control of the Company. The Credit Facility
is guaranteed by Heat Holdings Corp., Heat Holdings II Corp. and all of the
Company's domestic subsidiaries and secured by the Company's assets (including
the assets and stock of its domestic subsidiaries and a portion of the stock of
its foreign subsidiaries), and a pledge of the Company's stock.

TECHNOLOGIES, INC., a Delaware corporation (the "COMPANY"), each of the
GUARANTORS (as defined herein) and BANKERS TRUST COMPANY, a New York banking
corporation organized under the laws of the State of New York, as trustee (the
"TRUSTEE").

                  The Company has duly authorized the creation of an issue of 12
3/4% Senior Subordinated Notes due 2007, Series A (the "INITIAL NOTES"), and 12
3/4% Senior Subordinated Notes due 2007, Series B (the "EXCHANGE NOTES"), and,
to provide therefor, the Company and each Guarantor has duly authorized the

Notes, when duly issued and executed by the Company, and authenticated and
delivered hereunder, the valid obligations of the Company and to make this
Indenture a valid and binding agreement of the Company and the Guarantors, have
been done.

                  Each party agrees as follows for the benefit of the other
parties and for the equal and ratable benefit of the Holders:

                                    ARTICLE 1

                   DEFINITIONS AND INCORPORATION BY REFERENCE

Section 1.01.     DEFINITIONS.

                  "ACQUIRED INDEBTEDNESS" means Indebtedness of a Person
(including an Unrestricted Subsidiary) existing at the time such Person becomes
a Restricted Subsidiary or is merged into or consolidated with any other Person
or that is assumed in connection with the acquisition of assets from such Person
and, in each case, not incurred by such Person in connection with, or in
anticipation or contemplation of, such Person becoming a Restricted Subsidiary
or such merger, consolidation or acquisition.

                  "ADJUSTED NET ASSETS" of any Person at any date shall mean the
lesser of the amount by which the fair value of the property of such Person
exceeds the total amount of liabilities, including, without limitation,
contingent liabilities (after giving effect to all other fixed and contingent
liabilities), but excluding liabilities under the Guarantee of such Person at
such date and the present fair salable value of the assets of such Person at
such date exceeds the amount that will be required to pay the probable liability
of such Person on its debts (after giving effect to all other fixed and
contingent liabilities and after giving effect to any collection from any
Subsidiary of such Person in respect of the obligations of such Person under the
Guarantee of such Person), excluding Indebtedness in respect of the Guarantee of
such Person, as they become absolute and matured.

                  "ADDITIONAL INTEREST" has the meaning provided to such term in
the Registration Rights Agreement.

                  "AFFILIATE" means, with respect to any specific Person, any
other Person that directly or indirectly through one or more intermediaries
controls, or is controlled by, or is under common control with, such specified
Person. For the purposes of this definition, "control" (including, with
correlative meanings, the terms "controlling," "controlled by," and "under
common control with"), as used with respect to any Person, means the possession,
directly or indirectly, of the power to direct or cause the direction of the
management or policies of such Person, whether through the ownership of voting
securities, by agreement or otherwise; PROVIDED that, for purposes of Section
4.14, beneficial ownership of at least 10% of the voting securities of a Person,
either directly or indirectly, shall be deemed to be control.

                  (2) the acquisition by the Company or any Restricted

               Person or any other properties or assets of such Person other

                  "ASSET SALE" means any direct or indirect sale, issuance,

                                    ARTICLE 2

                                    THE NOTES

Section 2.01.     FORM AND DATING.

                  The Initial Notes and the Trustee's certificate of
authentication relating thereto shall be substantially in the form of EXHIBIT A
hereto. The Exchange Notes and the Trustee's certificate of authentication
relating thereto shall be substantially in the form of EXHIBIT B hereto. The
Notes may have notations, legends or endorsements required by law, stock
exchange rule or Depository rule or usage. The form of the Notes and any
notation, legend or endorsement on them shall be satisfactory to both the
Company and the Trustee. Each Note shall be dated the date of its issuance and
shall show the date of its authentication.

                  The terms and provisions contained in the Notes, annexed
hereto as EXHIBITS A and B, shall constitute, and are hereby expressly made, a
part of this Indenture and, to the extent applicable, the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.

                  The Notes shall be issued initially in the form of two or more
permanent global Notes (the "GLOBAL NOTES"). Notes offered and sold (i) in
reliance on Rule 144A shall be issued initially in the form of one or more
permanent Global Notes in registered form, substantially in the form set forth
in EXHIBIT A (the " RULE 144A GLOBAL NOTE") and (ii) in offshore transactions in
reliance on Regulation S shall be issued initially in the form of one or more
permanent global Notes in registered form, substantially in the form set forth
in Exhibit A (the "REGULATION S GLOBAL NOTE"), and in each case shall be
deposited with the Trustee, as custodian for the Depository, duly executed by
the Company and authenticated by the Trustee as hereinafter provided. The
aggregate principal amount of any Global Note may from time to time be increased
or decreased by adjustments made on the records of the Trustee, as custodian for
the Depository, as hereinafter provided.

Section 2.02.     EXECUTION AND AUTHENTICATION.

                  The Notes shall be executed on behalf of the Company by two
Officers of the Company or an Officer and the Secretary or Assistant Secretary
of the Company. Such signature may be either manual or facsimile. The Company's
seal may be impressed, affixed, imprinted or reproduced on the Notes and may be
in facsimile form.

                  If an Officer whose signature is on a Note no longer holds
that office at the time the Trustee authenticates the Note, the Note shall be
valid nevertheless.


<PAGE>
                                      -29-


                  A Note shall not be valid until an authorized signatory of the
Trustee or Authenticating Agent manually signs the certificate of authentication
on the Note. Such signature shall be conclusive evidence that the Note has been
authenticated under this Indenture.

                  The Trustee or an authentication agent (the "AUTHENTICATING
AGENT") shall authenticate (i) Initial Notes for original issue on the date of
this Indenture in the aggregate principal amount not to exceed $150,000,000 and
(ii) Exchange Notes from time to time for issue only in exchange for a like
principal amount of Initial Notes, in each case upon written orders of the
Company in the form of an Officers' Certificate. The Officers' Certificate shall
specify the amount of Notes to be authenticated, the date on which the Notes are
to be authenticated and the aggregate principal amount of Notes outstanding on
the date of authentication, whether the Notes are to be Initial Notes or
Exchange Notes, and shall further specify the amount of such Notes to be issued
as the Global Note or Certificated Notes. The aggregate principal amount of
Notes outstanding at any time may not exceed such amount, except as provided in
Section 2.07.

                  Notwithstanding the foregoing, all Notes issued under this
Indenture shall vote and consent together on all matters (as to which any of
such Notes may vote or consent) as one class and no series of Notes will have
the right to vote or consent as a separate class on any matter.

                  The Trustee, at the expense of the Company, may appoint an
Authenticating Agent to authenticate Notes. Any such appointment shall be
evidenced by an instrument signed by a Responsible Officer, a copy of which
shall be furnished to the Company. An Authenticating Agent may authenticate
Notes whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such Authenticating
Agent. An Authenticating Agent has the same right as an Agent to deal with the
Company and Affiliates of the Company.

                  The Notes shall be issuable only in registered form without
coupons and only in denominations of $1,000 and integral multiples thereof.

Section 2.03.     REGISTRAR AND PAYING AGENT.

                  The Company shall maintain an office or agency where Notes may
be presented for registration of transfer or for exchange ("REGISTRAR"), an
office or agency located in the Borough of Manhattan, City of New York, State of
New York where Notes may be presented for payment ("PAYING AGENT") and an office
or agency where notices and demands to or upon the Company in respect of the
Notes and this Indenture may be served. The Registrar shall keep a register of
the Notes and of their transfer and exchange. The Registrar shall provide the
Company a current copy of such register from time to time upon request of the
Company. The Company may have one or more co-Registrars and one or more
additional Paying Agents. Neither the Company nor any Affiliate of the Company
may act as Paying Agent. The Company may change any Paying Agent, Registrar or
co-Registrar without notice to any Noteholder.

                  The Company shall enter into an appropriate agency agreement
with any Agent not a party to this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall notify
the Trustee of the name and address of any such Agent. If the Company fails to
maintain a Registrar or Paying Agent, or agent for service of notices and
demands, or fails to give the foregoing notice, the Trustee shall act as such.
The Company initially appoints the Trustee as Registrar, Paying Agent and agent
for service of notices and demands in connection with the Notes.

                                      -30-


Section 2.04.     PAYING AGENT TO HOLD ASSETS IN TRUST.

                  The Company shall require each Paying Agent other than the
Trustee to agree in writing that each Paying Agent shall hold in trust for the
benefit of the Holders or the Trustee all assets held by the Paying Agent for
the payment of principal of, premium, if any, or interest on Notes (whether such
assets have been distributed to it by the Company or any other obligor on the
Notes), and shall promptly notify the Trustee in writing of any Default in
making any such payment. The Company at any time may require a Paying Agent to
distribute all assets held by it to the Trustee and account for any assets
disbursed and the Trustee may at any time during the continuance of any Payment
Default, upon written request to a Paying Agent, require such Paying Agent to
forthwith distribute to the Trustee all assets so held in trust by such Paying
Agent together with a complete accounting of such sums. Upon distribution to the
Trustee of all assets that shall have been delivered by the Company to the
Paying Agent, the Paying Agent shall have no further liability for such assets.

Section 2.05.     NOTEHOLDER LISTS.

                  The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of Holders. If the Trustee is not the Registrar, the Company shall
furnish or cause the Registrar to furnish to the Trustee on or before each and
in each year, and at such other times as the Trustee may request in writing, a
list in such form and as of such date as the Trustee may reasonably require of
the names and addresses of Holders which list may be conclusively relied on by
the Trustee.

Section 2.06.     TRANSFER AND EXCHANGE.

                  Subject to the provisions of Sections 2.15 and 2.16, when
Notes are presented to the Registrar or a co-Registrar with a written request to
register the transfer of such Notes or to exchange such Notes for an equal
principal amount of Notes of other authorized denominations of the same series,
the Registrar or co-Registrar shall register the transfer or make the exchange
as requested if its requirements for such transaction are met; PROVIDED,
HOWEVER, that the Notes presented or surrendered for registration of transfer or
exchange shall be duly endorsed or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Registrar or co-Registrar,
duly executed by the Holder thereof or his attorney duly authorized in writing.
To permit registrations of transfer and exchanges, the Company shall execute and
the Trustee shall authenticate Notes at the Registrar's or co-Registrar's
request. No service charge shall be made for any registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
transfer tax or similar governmental charge in connection therewith payable by
the transferor of such Notes (other than any such transfer taxes or similar
governmental charge payable upon exchanges or transfers pursuant to Section
2.10, 3.06, 4.13, 4.17, 4.24 or 9.06, in which event the Company shall be
responsible for the payment of such taxes).

                  The Registrar or co-Registrar shall not be required to
register the transfer of or exchange of any Note (i) during a period beginning
at the opening of business 15 days before the mailing of a notice of redemption
of Notes and ending at the close of business on the day of such mailing and (ii)
selected for redemption in whole or in part pursuant to Article 3, except the
unredeemed portion of any Note being redeemed in part.

                  Any Holder of a Global Note shall, by acceptance of such
Global Note, agree that transfers of beneficial interests in such Global Notes
may be effected only through a book entry system maintained by the Holder of
such Global Note (or its agent), and that ownership of a beneficial interest in
the Note shall be required to be reflected in a book entry.

Section 2.07.     REPLACEMENT NOTES.

                  If a mutilated Note is surrendered to the Trustee or if the
Holder presents evidence to the satisfaction of the Company and the Trustee that
the Note has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Note. An indemnity bond may be
required by the Company or the Trustee that is sufficient in the judgment of the
Company and the Trustee to protect the Company, the Trustee or any Agent from
any loss which any of them may suffer if a Note is replaced. In every case of
destruction, loss or theft, the applicant shall also furnish to the Company and
to the Trustee evidence to their satisfaction of the destruction, loss or the
theft of such Note and the ownership thereof. Each of the Company and the
Trustee may charge for its expenses (including without limitation attorneys'
fees and expenses) in replacing a Note. In the event any such mutilated, lost,
destroyed or wrongfully taken Note has become due and payable, the Company in
its discretion may pay such Note instead of issuing a new Note in replacement
thereof. The provisions of this Section 2.07 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to replacement
or payment of mutilated, lost, destroyed or wrongfully taken Notes.

                  Every replacement Note is an additional Obligation of the
Company.

Section 2.08.     OUTSTANDING NOTES.

                  Notes outstanding at any time are all Notes authenticated by
the Trustee except for those cancelled by it, those delivered to it for
cancellation, and those described in this Section 2.08 as not outstanding.

                  If a Note is replaced pursuant to Section 2.07 (other than a
mutilated Note surrendered for replacement), it ceases to be outstanding until
the Company and the Trustee receive proof satisfactory to each of them that the
replaced Note is held by a bona fide purchaser. A mutilated Note ceases to be
outstanding upon surrender of such Note and replacement thereof pursuant to
Section 2.07.

                  If on a Redemption Date or the Maturity Date, the Paying Agent
holds U.S. legal tender sufficient to pay all of the principal and interest due
on the Notes payable on that date and is not prohibited from paying such money
to the Holders thereof pursuant to the terms of this Indenture, then on and
after that date such Notes cease to be outstanding and interest on them ceases
to accrue.

Section 2.09.     TREASURY NOTES.

                  In determining whether the Holders of the required principal
amount of Notes have concurred in any direction, waiver, consent or notice,
Notes owned by the Company or any of its Affiliates shall be considered as
though they are not outstanding, except that for the purposes of determining
whether the Trustee shall be protected in relying on any such direction, waiver
or consent, only Notes which a Responsible Officer of the Trustee actually knows
are so owned shall be so considered. The Company shall notify the Trustee, in
writing, when it or any of its Affiliates repurchases or otherwise acquires
Notes, of the aggregate principal amount of such Notes so repurchased or
otherwise acquired.

Section 2.10.     TEMPORARY NOTES.

                  Until definitive Notes are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Notes upon receipt of a
written order of the Company in the form of an Officers' Certificate. The
Officers' Certificate shall specify the amount of temporary Notes to be
authenticated and the date on which the temporary Notes are to be authenticated.
Temporary Notes shall be substantially in the form of definitive Notes but may
have variations that the Company considers appropriate for temporary Notes.
Without

                                      -32-


unreasonable delay, the Company shall prepare and the Trustee shall authenticate
upon receipt of a written order of the Company pursuant to Section 2.02
definitive Notes in exchange for temporary Notes.

Section 2.11.     CANCELLATION.

                  The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee, or at the direction of the Trustee, the Registrar or the Paying
Agent, and no one else, shall cancel and, at the written direction of the
Company, dispose of and deliver evidence of such disposal of all Notes
surrendered for registration of transfer, exchange, payment or cancellation.
Subject to Section 2.07, the Company may not issue new Notes to replace Notes
that it has paid or delivered to the Trustee for cancellation. If the Company
shall acquire any of the Notes, such acquisition shall not operate as a
redemption or satisfaction of the Indebtedness represented by such Notes unless
and until the same are surrendered to the Trustee for cancellation pursuant to
this Section 2.11.

Section 2.12.     DEFAULTED INTEREST.

                  The Company shall pay interest on overdue principal (including
post-petition interest in a proceeding under Bankruptcy Law) at the rate of
interest then borne by the Notes. The Company shall, to the extent lawful, pay
interest on overdue installments of interest (without regard to any applicable
grace periods) at the rate of interest then borne by the Notes.

                  If the Company defaults in a payment of interest on the Notes,
it shall pay the defaulted interest, plus (to the extent lawful) any interest
payable on the defaulted interest to the Persons who are Holders on a subsequent
special record date, which date shall be the fifteenth day next preceding the
date fixed by the Company for the payment of defaulted interest or the next
succeeding Business Day if such date is not a Business Day. At least 15 days
before the subsequent special record date, the Company shall mail to each
Holder, as of a recent date selected by the Company, with a copy to the Trustee,
a notice that states the subsequent special record date, the payment date and
the amount of defaulted interest, and interest payable on such defaulted
interest, if any, to be paid.

                  Notwithstanding the foregoing, any interest which is paid
prior to the expiration of the 30-day period set forth in Section 6.01(b) shall
be paid to Holders as of the Record Date for the Interest Payment Date for which
interest has not been paid.

Section 2.13.     DEPOSIT OF MONEYS.

                  Prior to 10:00 a.m., New York City time, on each Interest
Payment Date, Redemption Date, Change of Control Payment Date, Excess Proceeds
Payment Date and Maturity Date, the Company shall have deposited with the Paying
Agent in immediately available funds U.S. legal tender sufficient to make
payments, if any, due on such Interest Payment Date, Redemption Date, Change of
Control Payment Date, Excess Proceeds Payment Date or Maturity Date, as the case
may be, in a timely manner which permits the Trustee to remit payment to the
Holders on such Interest Payment Date, Redemption Date, Change of Control
Payment Date, Excess Proceeds Payment Date or Maturity Date, as the case may be.
The principal and interest on Global Notes shall be payable to the Depository or
its nominee, as the case may be, as the sole registered owner and the sole
holder of the Global Notes represented thereby. The principal and interest on
Notes in certificated form shall be payable at the office of the Paying Agent.


<PAGE>
                                      -33-


Section 2.14.     CUSIP NUMBER.

                  The Company in issuing the Notes may use one or more "CUSIP"
numbers, and if so, the Trustee shall use such CUSIP numbers in notices of
redemption or exchange as a convenience to Holders; PROVIDED that any such
notice may state that no representation is made as to the correctness or
accuracy of the CUSIP numbers printed in the notice or on the Notes, and that
reliance may be placed only on the other identification numbers printed on the
Notes. The Company shall promptly notify the Trustee in writing of any change in
the CUSIP number.

Section 2.15.     BOOK-ENTRY PROVISIONS FOR GLOBAL NOTES.

                  (a) The Global Notes initially shall (i) be registered in the
name of the Depository or the nominee of such Depository, (ii) be delivered to
the Trustee as custodian for such Depository and (iii) bear legends as set forth
in Section 2.17.

                  Members of, or participants in, the Depository ("AGENT
MEMBERS") shall have no rights under this Indenture with respect to any Global
Note held on their behalf by the Depository or under the Global Note, and the
Depository may be treated by the Company, the Trustee and any agent of the
Company or the Trustee as the absolute owner of the Global Note for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Depository or impair, as between the Depository and its Agent Members, the
operation of customary practices governing the exercise of the rights of a
Holder.

                  (b) Interests of beneficial owners in the Global Notes may be
transferred or exchanged for Certificated Notes in accordance with the rules and
procedures of the Depository and the provisions of Section 2.16. In addition,
Certificated Notes shall be transferred to all beneficial owners in exchange for
their beneficial interests in Global Notes if (i) the Depository (x) notifies
the Company that it is unwilling or unable to continue as Depository for any
Global Note or (y) has ceased to be a clearing company registered under the
Exchange Act and, in each case, a successor depositary is not appointed by the
Company within 90 days of such notice, (ii) the Company, at its option, notifies
the Trustee in writing that it elects to cause the issuance of Certificated
Notes, or (iii) a Default or an Event of Default has occurred and is continuing
and the Registrar has received a written request from the Depository to issue
Certificated Notes.

                  (c) In connection with any transfer or exchange of a
portion of the beneficial interest in any Global Note to beneficial owners
pursuant to paragraph (b), the Registrar shall (if one or more Certificated
Notes are to be issued) reflect on its books and records the date and a decrease
in the principal amount of the Global Note in an amount equal to the principal
amount of the beneficial interest in the Global Note to be transferred, and the
Company shall execute, and the Trustee shall upon receipt of a written order
from the Company authenticate and make available for delivery, one or more
Certificated Notes of like tenor and amount.

                  (d) In connection with the transfer of Global Notes as an
entirety to beneficial owners pursuant to paragraph (b), the Global Notes shall
be deemed to be surrendered to the Trustee for cancellation, and the Company
shall execute, and the Trustee shall, upon receipt of an authentication order
from the Company in the form of an Officers' Certificate, authenticate and
deliver, to each beneficial owner identified by the Depository in writing in
exchange for its beneficial interest in the Global Notes, an equal aggregate
principal amount of Certificated Notes of authorized denominations.


<PAGE>
                                      -34-


                  (e) Any Certificated Note constituting a Restricted Security
delivered in exchange for an interest in a Global Note pursuant to paragraph
(b), (c) or (d) shall, except as otherwise provided by Section 2.16, bear the
Private Placement Legend (as defined).

                  (f) The Holder of any Global Note may grant proxies and
otherwise authorize any Person, including Agent Members and Persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Notes.

Section 2.16.     REGISTRATION OF TRANSFERS AND EXCHANGES.

                  (a) TRANSFER AND EXCHANGE OF CERTIFICATED NOTES. When
Certificated Notes are presented to the Registrar or co-Registrar with a
request:

                         (i) to register the transfer of the Certificated Notes;
                    or

                         (ii) to exchange such Certificated Notes for an equal
                    principal amount of Certificated Notes of other authorized
                    denominations,

the Registrar or co-Registrar shall register the transfer or make the exchange
as requested if the requirements under this Indenture as set forth in this
Section 2.16 for such transactions are met; PROVIDED, HOWEVER, that the
Certificated Notes presented or surrendered for registration of transfer or
exchange:

                         (i) shall be duly endorsed or accompanied by a written
                    instrument of transfer in form satisfactory to the Registrar
                    or co-Registrar, duly executed by the Holder thereof or his
                    attorney duly authorized in writing; and

                         (ii) in the case of Certificated Notes the offer and
                    sale of which have not been registered under the Securities
                    Act and are presented for transfer or exchange prior to (x)
                    the date which is two years after the later of the date of
                    original issue and the last date on which the Company or any
                    Affiliate of the Company was the owner of such Note, or any
                    predecessor thereto and (y) such later date, if any, as may
                    be required by any subsequent change in applicable law (the
                    "RESALE RESTRICTION TERMINATION DATE"), such Certificated
                    Notes shall be accompanied, in the sole discretion of the
                    Company, by the following additional information and
                    documents, as applicable:

                                   (A) if such Certificated Note is being
                              delivered to the Registrar or co-Registrar by a
                              Holder for registration in the name of such
                              Holder, without transfer, a certification to that
                              effect (substantially in the form of EXHIBIT C);
                              or

                                   (B) if such Certificated Note is being

         of this clause (II), the Company shall have received a transferee
         letter of representation (substantially in the form of EXHIBIT D) and,
         at the option of the Company, an Opinion of Counsel reasonably

         an endorsement on the applicable Global Note to reflect an increase in
         the aggregate amount of the Notes represented by the Global Note,

then the Registrar or co-Registrar shall cancel such Certificated Note and
cause, or direct the Depository to cause, in accordance with the standing
instructions and procedures existing between the Depository and the Registrar or
co-Registrar, the principal amount of Notes represented by the applicable Global
Note to be increased accordingly. If no Global Note representing Notes held by

outstanding, the Company shall issue and the Trustee shall, upon receipt of an
authentication order in the form of an Officers' Certificate in accordance with
Section 2.02, authenticate such a Global Note in the appropriate principal
amount.

                  (c) TRANSFER AND EXCHANGE OF GLOBAL NOTES. The transfer and

Global Note) and the Company shall issue and the Trustee shall, upon receipt of
an authentication order in the form of an Officers' Certificate in accordance
with Section 2.02, authenticate new Global Notes of the types so cancelled (or
the type so cancelled and applicable type required to represent the interest as
requested to be transferred) reflecting the applicable increase and decrease of
the principal amount of Notes represented by such types of Global Notes, giving
effect to such transfer. If the applicable type of Global Note required to
represent the interest as requested to be transferred is not outstanding at the
time of such request, the Company shall issue and the Trustee shall, upon
written instructions from the Company in accordance with Section 2.02,
authenticate a new Global Note of such type in principal amount equal to the
principal amount of the interest requested to be transferred.

                  (d) TRANSFER OF A BENEFICIAL INTEREST IN A GLOBAL NOTE FOR A
CERTIFICATED NOTE. (i) Any Person having a beneficial interest in a Global Note
may upon request exchange such beneficial interest for a Certificated Note. Upon

         certification from such Person to that effect (substantially in the
         form of EXHIBIT C); or

                  (B) if such beneficial interest is being transferred to a
         Qualified Institutional Buyer in accordance with Rule l44A, a
         certification to that effect (substantially in the form of EXHIBIT C);

         Counsel reasonably satisfactory to the Company to the effect that such
         transfer is in compliance with the Securities Act,

then the Registrar or co-Registrar will cause, in accordance with the standing

                  (f) PRIVATE PLACEMENT LEGEND. Upon the transfer, exchange or
replacement of Notes not bearing the Private Placement Legend, the Registrar or
co-Registrar shall deliver Notes that do not bear the Private Placement Legend.
Upon the transfer, exchange or replacement of Notes bearing the Private
Placement Legend, the Registrar or co-Registrar shall deliver only Notes that
bear the Private Placement Legend unless, and the Trustee is hereby authorized
to deliver Notes without the Private Placement Legend if, (i) the Resale
Restriction Termination Date shall have occurred, (ii) there is delivered to the
Trustee an Opinion of Counsel reasonably satisfactory to the Company and the
Trustee to the effect that neither such legend nor the related restrictions on
transfer are required in order to maintain compliance with the provisions of the
Securities Act or (iii) such Note has been sold pursuant to an effective

imposed under this Indenture or under applicable law with respect to any
transfer of any interest in any Note (including any transfers between or

or evidence as are expressly required by, and to do so if and when expressly

other written communications received pursuant to Section 2.15 or this Section
2.16. The Company shall have the right to inspect and make copies of all such

                                   REDEMPTION

Section 3.01.     NOTICES TO TRUSTEE.

                  If the Company elects to redeem Notes pursuant to paragraph 7
of the Notes, at least 60 days prior to the Redemption Date or during such other
period as the Trustee may agree to, the Company shall notify the Trustee in
writing of the Redemption Date, the principal amount of Notes to be redeemed and
the Redemption Price, and deliver to the Trustee an Officers' Certificate
stating that such redemption will comply with the conditions contained herein
and in the Notes, as appropriate.

Section 3.02.     SELECTION OF NOTES TO BE REDEEMED.

                  In the event that less than all of the Notes are to be
redeemed at any time, selection of the Notes to be redeemed shall be made by the
Trustee in compliance with the requirements of the principal securities
exchange, if any, on which such Notes are listed or, if such Notes are not then
listed on a national securities exchange, on a PRO RATA basis, by lot or by such
other method as the Trustee shall deem fair and appropriate; PROVIDED, HOWEVER,
that no Notes of a principal amount of $1,000 or less shall be redeemed in part;
PROVIDED, FURTHER, that if a partial redemption is made with the proceeds of any
Public Equity Offering, selection of the Notes or portions thereof for
redemption shall be made by the Trustee only on a PRO RATA basis or on as nearly
a PRO RATA basis as is practicable (subject to the procedures of the
Depository), unless such method is otherwise prohibited. The Trustee shall
promptly notify the Company of the Notes selected for redemption and, in the
case of any Notes selected for partial redemption, the principal amount thereof
to be redeemed.

Section 3.03.     NOTICE OF REDEMPTION.

                  Notice of redemption shall be mailed by first class mail at
least 30 but not more than 60 calendar days before the Redemption Date to each
Holder of Notes to be redeemed at its registered address. If any Note is to be
redeemed in part only, the notice of redemption that relates to such Note shall
state the portion of the principal amount thereof to be redeemed.

                  The notice shall identify the Notes to be redeemed (including
the CUSIP number(s) thereof) and shall state:

                  (1)  the Redemption Date;

                  (3) that, if any Note is being redeemed in part, the portion
         of the principal amount (equal to $1,000 in principal amount or any
         integral multiple thereof) of such Note to be redeemed and that, on and
         after the Redemption Date, upon surrender of such Note, a new Note or
         Notes in principal amount equal to the unredeemed portion thereof will
         be issued;


<PAGE>
                                      -40-


                  (4) the name, address and telephone number of the Paying
         Agent;

                  (5) that Notes called for redemption must be surrendered to
         the Paying Agent at the address specified to collect the Redemption
         Price plus accrued interest, if any;

                  (6) that, unless the Company defaults in its obligation to
         deposit U.S. legal tender with the Paying Agent in accordance with
         Section 3.05 hereof, interest on Notes called for redemption ceases to
         accrue on and after the Redemption Date and the only remaining right of
         the Holders is to receive payment of the Redemption Price plus accrued
         interest to the Redemption Date upon surrender of the Notes to the
         Paying Agent;

                  (7) the subparagraph of the Notes pursuant to which the Notes
         called for redemption are being redeemed; and

                  (8) if fewer than all the Notes are to be redeemed, the
         identification of the particular Notes (or portion thereof) to be
         redeemed, as well as the aggregate principal amount of Notes to be
         redeemed and the aggregate principal amount of Notes to be outstanding
         after such partial redemption.

Section 3.04.     EFFECT OF NOTICE OF REDEMPTION.

                  Once the notice of redemption described in Section 3.03 is
mailed, Notes called for redemption become due and payable on the Redemption
Date and at the Redemption Price, including any premium, plus accrued interest
to the Redemption Date, if any. Upon surrender to the Paying Agent, such Notes
shall be paid at the Redemption Price, including any premium, plus accrued
interest to the Redemption Date, if any; PROVIDED that if the Redemption Date is
after a Record Date and on or prior to the Interest Payment Date, the accrued
interest shall be payable to the Holder of the redeemed Notes registered on the
relevant Record Date.

Section 3.05.     DEPOSIT OF REDEMPTION PRICE.

                  On or prior to 10:00 a.m., New York City time, on each
Redemption Date, the Company shall have deposited with the Paying Agent in
immediately available funds U.S. legal tender sufficient to pay the Redemption
Price of and accrued interest on all Notes to be redeemed on that date. The
Paying Agent shall promptly return to the Company any U.S. legal tender so
deposited that is not required for that purpose upon the written request of the
Company.

                  On and after any Redemption Date, if U.S. legal tender
sufficient to pay the Redemption Price of and accrued interest on Notes called
for redemption shall have been made available in accordance with the preceding
paragraph, the Notes called for redemption will cease to accrue interest and the
only right of the Holders of such Notes will be to receive payment of the
Redemption Price of and, subject to the first proviso in Section 3.04, accrued
and unpaid interest on such Notes to the Redemption Date. If any Note called for
redemption shall not be so paid, interest will continue to accrue and be paid,
from the Redemption Date until such redemption payment is made, on the unpaid
principal of the Note and any interest not paid on such unpaid principal, in
each case, at the rate and in the manner provided for in Section 2.12.

Section 3.06.     NOTES REDEEMED IN PART.

take with respect thereto. The Officers' Certificate shall also notify the
Trustee should the Company elect to change the manner in which it fixes its
fiscal year end.

                  (b) Forthwith upon any Officer becoming aware (i) of any
Default or Event of Default or (ii) that any Holder seeks to exercise any remedy

the nature and period of existence thereof, it being understood that such
accountants shall not be liable directly or indirectly to any Person for any

or other existence of each Subsidiary, in accordance with the respective
organizational documents (as the same may be amended from time to time) of each
Subsidiary and the material rights (charter and statutory), licenses and
franchises of the Company and its Subsidiaries except where the failure to
preserve and keep in full force and effect any such rights, licenses and
franchise shall not have a material adverse effect on the financial condition,
business or results of operations or prospects of the Company and its
Subsidiaries taken as a whole; and PROVIDED that the Company shall not be
required to preserve any such right, license or franchise, or the corporate,
limited liability company, partnership or other existence of any of its
Subsidiaries, if the Board of Directors of the Company shall determine that the

the Company and its Subsidiaries, taken as a whole, and that the loss thereof is
not adverse in any material respect to the Holders.

                  The Company shall maintain an office or agency in the Borough
of Manhattan, The City of New York where Notes may be surrendered for

notices and demands to or upon the Company in respect of the Notes and this
Indenture may be served. The Company shall give prompt written notice to the
Trustee of the location, and any change in the location, of such office or
agency. If at any time the Company shall fail to maintain any such required

thereof, and of any governmental department, commission, board, regulatory
authority, bureau, agency and instrumentality of the foregoing, in respect of

all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in its judgment may be necessary, so that the business carried

Company or any of its Subsidiaries from discontinuing the use, operation or
maintenance of any of such properties, or disposing of any of them, if such
discontinuance or disposal is, in the judgment of the Board of Directors of the
Company or of the Board of Directors of the Subsidiary of the Company concerned,
or of an Officer (or other agent employed by the Company or of any of its
Subsidiaries) of the Company or any of its Subsidiaries having managerial
responsibility for any such property, desirable in the conduct of the business
of the Company or any Subsidiary of the Company, and if such discontinuance or
disposal is not adverse in any material respect to the Holders.

                  (b) The Company shall maintain, and shall cause its respective
Subsidiaries to maintain, insurance with carriers believed by the Company to be
responsible against such risks and in such amounts, and with such deductibles,
retentions, self-insured amounts and co-insurance provisions, as are customarily
carried by similar businesses of similar size, including property and casualty
loss, workers' compensation and interruption of business insurance.

Section 4.10.     LIMITATION ON ADDITIONAL INDEBTEDNESS.

                  (A) The Company will not, and will not permit any of the
Restricted Subsidiaries to, directly or indirectly, incur (as defined) any
Indebtedness (including Acquired Indebtedness); PROVIDED that if no Default or
Event of Default shall have occurred and be continuing at the time or as a
consequence of the incurrence of such Indebtedness, the Company may incur
Indebtedness (including Acquired Indebtedness) if after giving effect to the
incurrence of such Indebtedness and the receipt and application of the proceeds
thereof, the Company's Consolidated Fixed Charge Coverage Ratio is greater than
or equal to 2.0 to 1.

                  (B) Notwithstanding the foregoing, the Company and, to the
extent applicable, the Restricted Subsidiaries may incur Permitted Indebtedness;
PROVIDED that the Company will not incur any Permitted Indebtedness that ranks
junior in right of payment to the Notes that has a maturity or mandatory sinking
fund payment prior to the maturity of the Notes. Notwithstanding any other
provisions of this Section 4.10, (i) the maximum amount of Indebtedness that the
Company or a Restricted Subsidiary may incur pursuant to this covenant shall not
be deemed to be exceeded, with respect to any outstanding Indebtedness, due
solely to the result of fluctuations in the exchange rates of currencies and
(ii) in the event that an item of Indebtedness meets the criteria of more than
one of the categories of Permitted Indebtedness, the Company may, in its sole
discretion, classify (or reclassify) such item of Indebtedness in any manner
that complies with this covenant and such items of Indebtedness will be treated
as having been incurred pursuant to only one of such categories. Accrual of
interest, accretion or amortization of original discount and the payment of
interest in the form of additional Indebtedness will not be deemed to be an
incurrence of Indebtedness for purposes of this Section and accruals of
dividends or the payment of dividends on Disqualified Capital Stock in the form
of additional shares of the same class of Disqualified Capital Stock will not be
deemed an issuance of Disqualified Capital Stock for purposes of this Section.

                  so converted, exercised or exchanged, as the case may be,

                           (c) without duplication, the sum of:

                                  (i) the aggregate amount returned in cash on

as the case may be. For purposes of this covenant, Indebtedness is deemed to be
senior in right of payment to the Notes or any Guarantees if it is not expressly
subordinated in right of payment to Senior Indebtedness at least to the same
extent as the Notes and any Guarantees, as the case may be, are subordinated to
such Senior Indebtedness.

Section 4.13.     LIMITATION ON CERTAIN ASSET SALES.

                  The Company will not, and will not permit any of the
Restricted Subsidiaries to, consummate an Asset Sale unless

                  (1) the Company or such Restricted Subsidiary, as the case may
         be, receives consideration at the time of such sale or other
         disposition at least equal to the fair market value of the assets sold
         or otherwise disposed of (as determined in good faith by the Board of
         Directors of the Company and evidenced by a Board Resolution);

                  (2) not less than 75% of the consideration received by the
         Company or such Restricted Subsidiary, as the case may be, is in the
         form of cash or Cash Equivalents; PROVIDED that the amount of

                         (a) any liabilities (as shown on the Company's or such
              Restricted Subsidiary's most recent balance sheet) of the Company
              or any of the Restricted Subsidiaries (other

              than contingent liabilities and liabilities that are by their
              terms subordinated to the Notes) that are assumed by the
              transferee of any such assets shall be deemed to be cash for
              purposes of this clause (2); and

                         (b) any promissory notes and other non-cash
              consideration received by the Company or any Restricted
              Subsidiary from such Asset Sale that are converted by the Company
              or such Restricted Subsidiary into cash within 180 days of the
              applicable Asset Sale shall be deemed to be cash for purposes of
              this clause (2);

                  (3) the Asset Sale Proceeds received by the Company or such
         Restricted Subsidiary are applied

                                    (a) first, to the extent the Company or any
                           such Restricted Subsidiary, as the case may be,
                           elects, or is required, to prepay, repay or purchase
                           Indebtedness under any then existing Senior
                           Indebtedness of the Company or any such Restricted
                           Subsidiary within 270 days following the receipt of
                           the Asset Sale Proceeds from any Asset Sale; PROVIDED
                           that any such repayment shall result in a permanent
                           reduction of the commitments thereunder in an amount
                           equal to the principal amount so repaid;

                                    (b) second, to the extent of the balance of
                           Asset Sale Proceeds after application as described
                           above, to the extent the Company elects, to an
                           investment in assets (including Capital Stock or
                           other securities purchased in connection with the
                           acquisition of Capital Stock or property of another
                           Person) used or useful in businesses similar or
                           ancillary to the business of the Company or any such
                           Restricted Subsidiary as conducted on the Issue Date;
                           PROVIDED that

                                            (i) such investment occurs or the
                                    Company or any such Restricted Subsidiary
                                    enters into contractual commitments to make
                                    such investment, subject only to customary
                                    conditions (other than the obtaining of
                                    financing), within 270 days following
                                    receipt of such Asset Sale Proceeds and

                                            (ii) the Asset Sale Proceeds so
                                    contractually committed are so applied
                                    within 360 days following the receipt of
                                    such Asset Sale Proceeds; and

                                    (c) third, if on such 270th day in the case
                           of clauses (3)(a) and (3)(b)(i) or on such 360th day
                           in the case of clause (3)(b)(ii) with respect to any
                           Asset Sale, the Available Asset Sale Proceeds exceed
                           $7.5 million, the Company shall apply an amount equal
                           to the Available Asset Sale Proceeds to an offer to
                           repurchase the Notes, at a purchase price in cash
                           equal to 100% of the principal amount thereof plus
                           accrued and unpaid interest, if any, to the purchase
                           date (an "Excess Proceeds Offer"). If an Excess
                           Proceeds Offer is not fully subscribed, the Company
                           may retain the portion of the Available Asset Sale
                           Proceeds not required to repurchase Notes and use
                           such proceeds for general corporate purposes subject
                           to the other provisions of this Indenture.

                  Pending the final application of any Asset Sale Proceeds, the
Company or such Restricted Subsidiary may temporarily reduce Indebtedness under
a revolving credit facility, if any, or otherwise invest such Asset Sale
Proceeds in Cash Equivalents.

the Company shall mail, within 30 days following the date specified in clause
(3)(c) above, a notice to the holders stating:

                   (1) that the Excess Proceeds Offer is being made pursuant to
         this Section 4.13;

                   (2) that such Holders have the right to require the Company
         to apply the Available Asset Sale Proceeds to repurchase such Notes at
         a purchase price in cash equal to 100% of the principal amount thereof
         plus accrued and unpaid interest, if any, to the purchase date which
         shall be no earlier than 30 days and not later than 60 days from the
         date such notice is mailed (the "EXCESS PROCEEDS PAYMENT DATE");

                   (3) that any Note not tendered or accepted for payment will
         continue to accrue interest;

                   (4) that any Notes accepted for payment pursuant to the
         Excess Proceeds Offer shall cease to accrue interest after the Excess
         Proceeds Payment Date;

                   (5) that Holders accepting the offer to have their Notes
         purchased pursuant to an Excess Proceeds Offer will be required to
         surrender the Notes, with the form entitled "Option of Holder to Elect
         Purchase" on the reverse of the Note completed, to the Paying Agent at
         the address specified in the notice prior to the close of business on
         the Business Day preceding the Excess Proceeds Payment Date;

                   (6) that Holders will be entitled to withdraw their
         acceptance of the Excess Proceeds Offer if the Paying Agent receives,
         not later than the close of business on the third Business Day
         preceding the Excess Proceeds Payment Date, a telegram, telex,
         facsimile transmission or letter setting forth the name of the Holder,
         the principal amount of the Notes delivered for purchase, and a
         statement that such Holder is withdrawing his election to have such
         Notes purchased;

                   (7) that if the aggregate principal amount of Notes
         surrendered by Holders exceeds the amount of Excess Proceeds, Company
         shall select the Notes to be purchased on a PRO RATA basis (with such
         adjustments as may be deemed appropriate by the Company so that only
         Notes in denominations of $1,000 or integral multiples thereof, shall
         be purchased);

                   (8) that Holders whose Notes are being purchased only in part
         will be issued new Notes equal in principal amount to the unpurchased
         portion of the Notes surrendered, PROVIDED that each Note purchased and
         each such new Note issued shall be in an original principal amount in
         denominations of $1,000 and integral multiples thereof;

                   (9) the calculations used in determining the amount of
         Available Asset Sale Proceeds to be applied to the purchase of such
         Notes;

                  (10) any other procedures that a Holder must follow to accept
         an Excess Proceeds Offer or effect withdrawal of such acceptance; and

                  (11) the name and address of the Paying Agent.

                  On the Excess Proceeds Payment Date, the Company shall, to the
extent lawful, (1) accept for payment, on a PRO RATA basis to the extent
necessary, Notes or portions thereof tendered pursuant to the Excess Proceeds
Offer, (2) deposit with the Paying Agent U.S. legal tender sufficient to pay the
purchase price plus accrued and unpaid interest, if any, on the Notes to be
purchased or portions thereof on or prior to 11:00 a.m., New

York City time, (3) deliver or cause to be delivered to the Trustee Notes so
accepted together with an Officers' Certificate stating that such Notes or
portions thereof were accepted for payment by the Company in accordance with the
terms of this Section 4.13. The Paying Agent shall promptly mail to each Holder,
whose Notes were so accepted, payment in an amount equal to the purchase price
for such Notes, and the Company shall execute and issue, and the Trustee shall
promptly authenticate and make available for delivery to such Holder, a new Note
equal in principal amount to any unpurchased portion of the Notes surrendered;
PROVIDED that each such new Note shall be issued in an original principal amount
in denominations of $1,000 and integral multiples thereof. The Company will
publicly announce the results of the Excess Proceeds Offer on the Excess
Proceeds Payment Date.

                  (C) In the event of the transfer of substantially all of the
property and assets of the Company and its Restricted Subsidiaries as an
entirety to a Person in a transaction permitted under Section 5.01 of this
Indenture, the successor Person shall be deemed to have sold the properties and
assets of the Company and the Restricted Subsidiaries not so transferred for
purposes of this Section 4.13, and shall comply with the provisions of this
Section 4.13 with respect to such deemed sale as if it were an Asset Sale.

                  (D) The Company will comply with the requirements of Rule
14e-1 under the Exchange Act and other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with the repurchase of Notes pursuant to an Excess Proceeds Offer. To the extent
that the provisions of any securities laws or regulations conflict with this
Section 4.13, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under this
Section 4.13 by virtue thereof.

Section 4.14.     LIMITATION ON TRANSACTIONS WITH AFFILIATES.

                  (A) The Company will not, and will not permit any of the
Restricted Subsidiaries to, directly or indirectly, enter into or suffer to
exist any transaction or series of related transactions (including, without
limitation, the sale, purchase, exchange or lease of assets, property or
services) with any Affiliate (each an "Affiliate Transaction") or extend, renew,
waive or otherwise modify the terms of any Affiliate Transaction entered into
prior to the Issue Date unless

                         (1) such Affiliate Transaction is between or among the
         Company and the Restricted Subsidiaries or

                         (2) the terms of such Affiliate Transaction are fair
         and reasonable to the Company or such Restricted Subsidiary, as the
         case may be, and the terms of such Affiliate Transaction are at least
         as favorable as the terms that could be obtained by the Company or
         such Restricted Subsidiary, as the case may be, in a comparable
         transaction made on an arm's-length basis between unaffiliated
         parties.

                  In any Affiliate Transaction (or any series of related
Affiliate Transactions that are similar or part of a common plan) involving an
amount or having a fair market value in excess of $2.5 million that is not
permitted under clause (1) above, the Company must obtain a Board Resolution
certifying that such Affiliate Transaction complies with clause (2) above. In
any Affiliate Transaction (or any series of related Affiliate Transactions that
are similar or part of a common plan) involving an amount or having a fair
market value in excess of $5.0 million that is not permitted under clause (1)
above, the Company must obtain a favorable written opinion as to the fairness of
such transaction or transactions, as the case may be, from an Independent
Financial Advisor.

                  (B) The foregoing provisions will not apply to


<PAGE>
                                      -51-


                  (1) any Restricted Payment that is not prohibited by the
         provisions described under Section 4.11 or any Permitted Investment;

                  (2) reasonable fees and compensation paid to and indemnity
         provided on behalf of, officers, directors or employees of the Company
         or any Restricted Subsidiary as determined in good faith by the
         Company's Board of Directors or senior management;

                  (3) any agreement as in effect as of the Issue Date or any
         amendment thereto or any transaction contemplated thereby (including
         pursuant to any amendment thereto) in any replacement agreement
         thereto so long as any such amendment or replacement agreement is not
         more disadvantageous to the holders in any material respect than the
         original agreement as in effect on the Issue Date;

                  (4) any transaction permitted under Section 5.01; or

                  (5) transactions with Affiliates solely in their capacity as
         holders of Indebtedness or Capital Stock of the Company or any of its
         Subsidiaries where such Affiliates are treated no more favorably than
         holders of such Indebtedness or such Capital Stock generally.

Section 4.15.     LIMITATIONS ON LIENS.

                  (A) The Company will not, and will not permit any Restricted
Subsidiary to, create, incur or otherwise cause or suffer to exist or become
effective any Liens of any kind (other than Permitted Liens) upon any property
or asset of the Company or any of the Restricted Subsidiaries or any shares of
Capital Stock or Indebtedness of any Restricted Subsidiary that owns property or
assets, now owned or hereafter acquired, unless

                  (1) if such Lien secures Indebtedness that ranks equally with
         the Notes, then the Notes are secured on an equal and ratable basis
         with the obligations so secured until such time as such obligation is
         no longer secured by a Lien or

                  (2) if such Lien secures Indebtedness that is subordinated to
         the Notes, any such Lien shall be subordinated to the Lien granted to
         the holders of the Notes to the same extent as such Indebtedness is
         subordinated to the Notes.

Section 4.16.     LIMITATIONS ON INVESTMENTS.

                  The Company will not, and will not permit any Restricted
Subsidiary to, make any Investment other than

                  (1) a Permitted Investment or

                  (2) an Investment that is made after the Issue Date as a
         Restricted Payment in compliance with Section 4.11.

Section 4.17.     CHANGE OF CONTROL.

                  (A) Upon the occurrence of a Change of Control, the Company
shall be obligated to make an offer to purchase (the "CHANGE OF CONTROL OFFER")
each Holder's outstanding Notes at a purchase price (the


<PAGE>
                                      -52-


"CHANGE OF CONTROL PURCHASE PRICE") equal to 101% of the principal amount
thereof plus accrued and unpaid interest, if any, to the Change of Control
Payment Date in accordance with the procedures set forth below.

                  (B) Within 20 days of the occurrence of a Change of Control,
the Company shall (i) cause a notice of the Change of Control Offer to be sent
at least once to the Dow Jones News Service or similar business new service in
the United States and (ii) send by first-class mail, postage prepaid, to the
Trustee and to each holder of the Notes, at the address appearing in the
register maintained by the Registrar of the Notes, a notice stating:

                  (1) that the Change of Control Offer is being made pursuant to
         this Section 4.17 and that all Notes tendered will be accepted for
         payment;

                  (2) the Change of Control Purchase Price and the purchase date
         (which shall be a Business Day no earlier than 30 days nor later than
         60 days from the date such notice is mailed (the "CHANGE OF CONTROL
         PAYMENT DATE"));

                  (3) that any Note not tendered will continue to accrue
         interest;

                  (4) that, unless the Company defaults in the payment of the
         Change of Control Purchase Price, any Notes accepted for payment
         pursuant to the Change of Control Offer shall cease to accrue interest
         after the Change of Control Payment Date;

                  (5) that Holders accepting the offer to have their Notes
         purchased pursuant to a Change of Control Offer will be required to
         surrender the Notes, with the form entitled "Option of Holder to Elect
         Purchase" on the reverse of the Note completed to the Paying Agent at
         the address specified in the notice prior to the close of business on
         the Business Day preceding the Change of Control Payment Date;

                  (6) that Holders will be entitled to withdraw their acceptance
         if the Paying Agent receives, not later than the close of business on
         the third Business Day preceding the Change of Control Payment Date, a
         telegram, facsimile transmission or letter setting forth the name of
         the Holder, the principal amount of the Notes delivered for purchase,
         and a statement that such Holder is withdrawing his election to have
         such Notes purchased;

                  (7) that Holders whose Notes are being purchased only in part
         will be issued new Notes equal in principal amount to the unpurchased
         portion of the Notes surrendered;

                  (8) any other procedures that a Holder must follow to accept a
         Change of Control Offer or effect withdrawal of such acceptance; and

                  (9) the name and address of the Paying Agent.

         On the Change of Control Payment Date, the Company shall, to the
         extent lawful,

                  (1) accept for payment Notes or portions thereof tendered
         pursuant to the Change of Control Offer;

                  (2) deposit with the Paying Agent money sufficient to pay the
         purchase price of all Notes or portions thereof so tendered; and


<PAGE>
                                      -53-


                  (3) deliver or cause to be delivered to the Trustee for
         cancellation Notes so accepted together with an Officers' Certificate
         stating the Notes or portions thereof tendered to the Company.

                  The Paying Agent shall promptly mail to each holder of Notes
so accepted payment in an amount equal to the purchase price for such Notes, and
the Company shall execute and issue, and the Trustee shall promptly authenticate
and mail to such holder, a new Note equal in principal amount to any unpurchased
portion of the Notes surrendered; PROVIDED that each such new Note shall be
issued in an original principal amount in denominations of $1,000 and integral
multiples thereof.

                  (C) If the Senior Credit Facility is in effect, or any amounts
are owing thereunder or in respect thereof, at the time of the occurrence of a
Change of Control, prior to the mailing of the notice to Holders described in
the second preceding paragraph, but in any event within 20 days following any
Change of Control, the Company covenants to

                  (1) repay in full all obligations and terminate all
         commitments under or in respect of the Senior Credit Facility and all
         other Senior Indebtedness the terms of which require repayment upon a
         Change of Control or offer to repay in full all obligations and
         terminate all commitments under or in respect of the Senior Credit
         Facility and all such Senior Indebtedness and repay the Indebtedness
         owed to each such lender who has accepted such offer or

                  (2) obtain the requisite consents under the Senior Credit
         Facility and all such other Senior Indebtedness to permit the
         repurchase of the Notes as described above.

                  The Company must first comply with the covenant described in
the preceding sentence before it shall be required to purchase Notes in the
event of a Change of Control; PROVIDED that the Company's failure to comply with
the covenant described in the preceding sentence constitutes an Event of Default
described in clause (C) under Section 6.01 if not cured within 60 days after the
notice required by such clause.

                  (D) (1) If the Company or any Restricted Subsidiary has issued
any (a) outstanding Indebtedness that is subordinated in right of payment to the
Notes or (b) Preferred Stock, and the Company or such Restricted Subsidiary is
required to make a Change of Control Offer or to make a distribution with
respect to such subordinated Indebtedness or Preferred Stock in the event of a
Change of Control, the Company shall not consummate any such offer or

                  The Company will not consolidate with, merge with or into, or
sell, assign, transfer, lease, convey or otherwise dispose of (or cause or
permit any Restricted Subsidiary to sell, assign, transfer, lease, convey or
otherwise dispose of) all or substantially all of its assets (determined on a
consolidated basis for the Company and the Restricted Subsidiaries), whether as
an entirety or substantially as an entirety in one transaction or a series of
related transactions, to any Person unless:

                  (1) the Company shall be the continuing Person, or the Person
          (if other than the Company) formed by such consolidation or into which
          the Company is merged or to which the properties and assets of the

          disposed of shall be a corporation or a limited liability company
          organized and existing under the laws of the United States or any
          State thereof or the District of Columbia and shall expressly assume,
          by a supplemental indenture, executed and delivered to the Trustee, in
          form satisfactory to the Trustee, all of the obligations of the
          Company under this Indenture and the Notes and the obligations
          thereunder shall remain in full force and effect;

                  (2) immediately before and immediately after giving effect to
          such transaction, no Default or Event of Default shall have occurred
          and be continuing;

                  (3) immediately after giving effect to such transaction on a
          PRO FORMA basis the Company or such Person could incur at least $1.00
          of additional Indebtedness (other than Permitted Indebtedness) under
          Section 4.10; and

                  (4) the Company shall deliver, or cause to be delivered, to
          the Trustee, in form and substance reasonably satisfactory to the
          Trustee, an Officers' Certificate and an Opinion of Counsel, each
          stating that such consolidation, merger or transfer and the
          supplemental indenture in respect thereto comply with this provision
          and that all conditions precedent herein provided for relating to such
          transaction or transactions have been complied with.

                  Notwithstanding the foregoing, the Company or any Guarantor
may merge or consolidate with or transfer substantially all of its assets to an
Affiliate that has no significant assets or liabilities and was formed solely
for the purpose of changing the jurisdiction of organization of the Company or
the form of organization of the Company so long as the amount of Indebtedness of
the Company and its Restricted Subsidiaries is not

                                      -58-


increased thereby and that the successor assumes all obligations of the Company
or such Restricted Subsidiary, as the case may be, under this Indenture, the
Notes and the Registration Rights Agreement.

                  For purposes of the foregoing, the transfer (by lease,
assignment, sale or otherwise, in a single transaction or series of
transactions) of all or substantially all of the properties or assets of one or
more Restricted Subsidiaries of the Company the Capital Stock of which
constitutes all or substantially all of the properties and assets of the Company
shall be deemed to be the transfer of all or substantially all of the properties
and assets of the Company.

                  Each Guarantor (other than any Guarantor whose Guarantee is to
be released in accordance with the terms of the Guarantee and the Indenture in
connection with any transaction complying with Section 4.13) will not, and the
Company will not cause or permit any Guarantor to, consolidate with or merge
with or into any Person other than the Company or any other Guarantor unless:

                  (1) the entity formed by or surviving any such consolidation
          or merger (if other than the Guarantor) or to which such sale, lease,
          conveyance or other disposition shall have been made is a corporation
          or limited liability company organized and existing under the laws of
          the United States or any State thereof or the District of Columbia;

                  (2) such entity assumes by supplemental indenture all of the
          obligations of the Guarantor on the Guarantee;

                  (3) immediately after giving effect to such transaction, no
          Default or Event of Default shall have occurred and be continuing; and

                  (4) immediately after giving effect to such transaction and
          the use of any net proceeds therefrom on a PRO FORMA basis, the
          Company could satisfy the provisions of clause (3) of the first
          paragraph of this Section;

                  PROVIDED, HOWEVER, that the foregoing provision shall not
apply in the case of the merger of a Guarantor with another person in a
transaction that constitutes an Asset Sale.

                  Any merger or consolidation of a Guarantor with and into the
Company (with the Company being the surviving entity) or another Guarantor that
is a Restricted Subsidiary of the Company need only comply with clause (4) of
the first paragraph of this Section.

                  Nothing in this Section shall be deemed to prevent the
consummation of the Merger or the conversion of the Company's domestic
Restricted Subsidiaries into limited liability companies immediately following
consummation of the Merger.

Section 5.02.     SUCCESSOR PERSON SUBSTITUTED.

                  Upon any consolidation, merger, conveyance or any transfer of
all or substantially all of the assets of the Company in accordance with Section
5.01 above, the successor entity formed by such consolidation or into which the
Company or any such Restricted Subsidiary is merged or to which such transfer is
made shall succeed to, and be substituted for, and may exercise every right and
power of, the Company or such Restricted Subsidiary, as the case may be, under
this Indenture with the same effect as if such successor entity had been named
as the Company or such Restricted Subsidiary, as the case may be, herein, and
thereafter the predecessor entity shall be relieved of all obligations and
covenants under this Indenture and the Notes.

amount of the Notes then outstanding may declare to be immediately due and
payable the entire principal amount of all the Notes then outstanding plus
accrued interest to the date of acceleration and (1) the same shall become
immediately due and payable or (2) if there are any amounts outstanding under
the Senior Credit Facility, the same shall become immediately due and payable
upon the first to occur of an acceleration under the Senior Credit Facility and
five Business Days after receipt by the Company and the representative under the
Senior Credit Facility of a notice of acceleration; PROVIDED, HOWEVER, that
after such acceleration but before a judgment or decree based on such
acceleration is obtained by the Trustee, the Holders of a majority in aggregate
principal amount of outstanding Notes may rescind and annul such acceleration
if:

                  (1) all Events of Default, other than nonpayment of principal,
         premium, if any, or interest that has become due solely because of the
         acceleration, have been cured or waived;


<PAGE>
                                      -61-


                  (2) to the extent the payment of such interest is lawful,
         interest on overdue installments of interest and overdue principal,
         which has become due otherwise than by such declaration of
         acceleration, has been paid;

                  (3) if the Company has paid the Trustee its reasonable
         compensation and reimbursed the Trustee for its expenses, disbursements
         and advances; and

                  (4) in the event of the cure or waiver of an Event of Default
         of the type described in Section 6.01(f) or (g) above, the Trustee
         shall have received an Officers' Certificate and an Opinion of Counsel
         that such Event of Default has been cured or waived.

No such rescission shall affect any subsequent Default or impair any right
consequent thereto. In case an Event of Default with respect to the Company of
the type described in Section 6.01(f) or (g) above shall occur, the principal,
premium and interest amount with respect to all of the Notes shall be due and
payable immediately without any declaration or other act on the part of the
Trustee or the Holders.

Section 6.03.     OTHER REMEDIES.

                  If an Event of Default occurs and is continuing, the Trustee,
in its own name or as trustee of an express trust, may pursue any available
remedy by proceeding at law or in equity to collect the payment of principal of,
or premium, if any, and interest on the Notes or to enforce the performance of
any provision of the Notes or this Indenture and may take any necessary action
requested of it as Trustee to settle, compromise, adjust or otherwise conclude
any proceedings to which it is a party.

                  The Trustee may maintain a proceeding even if it does not
possess any of the Notes or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any Noteholder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative to the
extent permitted by law.

Section 6.04.     WAIVER OF PAST DEFAULTS AND EVENTS OF DEFAULT.

                  Subject to Sections 2.09, 6.02, 6.07 and 8.02, the Holders of
a majority in aggregate principal amount of the Notes then outstanding have the
right, on behalf of all Holders, to waive any past or existing Default or
compliance with any provision under this Indenture EXCEPT a Default in the
payment of the principal of, or interest or premium, if any, on any Note as
specified in clauses (a) and (b) of Section 6.01 or in respect of a covenant or
a provision that cannot be modified or amended without the consent of all
Holders as provided for in Section 8.02. The Company shall deliver to the
Trustee an Officers' Certificate stating that the requisite percentage of
Holders have consented to such waiver and providing evidence reasonably
satisfactory to the Trustee of such consents. In case of any such waiver, the
Company, the Trustee and the Holders shall be restored to their former positions
and rights hereunder and under the Notes, respectively. This paragraph of this
Section 6.04 shall be in lieu of ss. 316(a)(1)(B) of the TIA and such ss.
316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the
Notes, as permitted by the TIA.

                  Upon any such waiver, such Default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured for
every purpose of this Indenture, but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any right consequent
thereto.

Section 6.05.     CONTROL BY MAJORITY.

                  Subject to Section 2.09, the Holders of a majority in
aggregate principal amount of the then outstanding Notes have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee by this Indenture. The Trustee, however, may refuse to follow any
direction that conflicts with law or this Indenture or that the Trustee
determines may be unduly prejudicial to the rights of another Noteholder not
taking part in such direction, and the Trustee shall have the right to decline
to follow any such direction if the Trustee, being advised by counsel,
determines that the action so directed may not lawfully be taken or if the
Trustee in good faith shall, by a Responsible Officer, determine that the
proceedings so directed may involve it in personal liability; PROVIDED that the
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction. In the event the Trustee takes any action or
follows any direction pursuant to this Indenture, the Trustee shall be entitled
to indemnification satisfactory to it against any loss or expense caused by
taking such action or following such direction. This Section 6.05 shall be in
lieu of ss. 316(a)(1)(A) of the TIA, and such ss. 316(a)(1)(A) of the TIA is
hereby expressly excluded from this Indenture and the Notes, as permitted by the
TIA.

Section 6.06.     LIMITATION ON SUITS.

                  Subject to Section 6.07 below, no Holder has any right to
institute any proceeding with respect to this Indenture or any remedy hereunder
unless:

                  (1)  the Holder gives the Trustee written notice of a
         continuing Event of Default;

                  (2) the Holders of at least 25% in aggregate principal amount
         of the outstanding Notes make a written request to the Trustee to
         pursue the remedy;

                  (3) such Holder or Holders offer to the Trustee indemnity
         satisfactory to the Trustee against any loss, liability or expense
         which may be incurred in compliance with such request;

                  (4) the Trustee fails to institute such proceeding within 60
         days after receipt of such notice and the offer of indemnity; and

                  (5) the Trustee has not received directions inconsistent with
         such written request during such 60-day period by the Holders of a
         majority in aggregate principal amount of the outstanding Notes.

                  A Noteholder may not use this Indenture to prejudice the
rights of another Noteholder or to obtain a preference or priority over another
Noteholder.

Section 6.07.     RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

                  Notwithstanding any other provision of this Indenture, the
right of any Holder to receive payment of principal of, or premium, if any, or
accrued interest of any Note held by such Holder on or after the respective due
dates expressed in such Note, or to bring suit for the enforcement of any such
payment on or after such respective dates, is absolute and unconditional and
shall not be impaired or affected without the consent of such Holder.

Section 6.08.     COLLECTION SUIT BY TRUSTEE.

                  If an Event of Default in payment of principal, premium, if
any, or interest specified in Section 6.01(a) or (b) occurs and is continuing,
the Trustee may recover judgment in its own name and as trustee of an express
trust against the Company for the whole amount of unpaid principal, premium and
accrued interest remaining unpaid, together with, to the extent that payment of
such interest is lawful, interest on overdue principal and interest on overdue
installments of interest, in each case at the rate set forth in Section 4.01,
and such further amounts as shall be sufficient to cover the costs and expenses
of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel.

Section 6.09.     TRUSTEE MAY FILE PROOFS OF CLAIM.

                  The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders allowed in any judicial proceedings relative to the Company (or any
other obligor upon the Notes), its creditors or its property and shall be
entitled and empowered to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same after
deduction of its charges and expenses to the extent that any such charges and
expenses are not paid out of the estate in any such proceedings and any
custodian in any such judicial proceeding is hereby authorized by each
Noteholder to make such payments to the Trustee, and in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due to it for the compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07.

                  Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any
Noteholder any plan or reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to authorize the
Trustee to vote in respect of the claim of any Noteholder in any such
proceedings.

Section 6.10.     PRIORITIES.

                  If the Trustee collects any money pursuant to this Article 6,
it shall pay out the money in the following order:

                  FIRST:  to the Trustee for amounts due under Section 7.07;

                  SECOND:  if the Holders are forced to proceed against the
          Company or any Guarantor directly without the Trustee, to Holders for
          their collection costs;

                  THIRD:  to Holders for amounts due and unpaid on the Notes
          for principal, premium, if any, and interest as to each, ratably,
          without preference or priority of any kind, according to the amounts
          due and payable on the Notes; and

                  FOURTH:  to the Company or, to the extent the Trustee collects
          any amounts from any Guarantor, to such Guarantor.

                  The Trustee, upon prior written notice to the Company, may fix
a record date and payment date for any payment to Holders pursuant to this
Section 6.10.

Section 6.11.     UNDERTAKING FOR COSTS.

                  In any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken or
omitted by it as Trustee, a court in its discretion may require the filing by
any party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a
Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in
principal amount of the Notes then outstanding.

                                    ARTICLE 7

                                     TRUSTEE

Section 7.01.     DUTIES OF TRUSTEE.

                  (a) If a Default or an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture and use the same degree of care and skill in its exercise
thereof as a prudent person would exercise or use under the circumstances in the
conduct of such person's own affairs.

                  (b)      Except during the continuance of a Default or an
Event of Default:

                  (1) The Trustee need perform only those duties as are
          specifically set forth in this Indenture and no covenants or
          obligations shall be implied in this Indenture against the Trustee.

                  (2) In the absence of bad faith on its part, the Trustee may
          conclusively rely, as to the truth of the statements and the
          correctness of the opinions expressed therein, upon certificates or
          opinions furnished to the Trustee and conforming to the requirements
          of this Indenture. However, the Trustee shall examine the certificates
          and opinions to determine whether or not they conform in form to the
          requirements of this Indenture.

                  (c) Notwithstanding anything to the contrary herein contained,
          the Trustee may not be relieved from liability for its own negligent
          action, its own negligent failure to act or its own willful
          misconduct, except that:

                  (1) This paragraph does not limit the effect of paragraph (b)
          of this Section 7.01.

                  (2) The Trustee shall not be liable for any error of judgment
          made in good faith by a Responsible Officer, unless it is conclusively
          determined by a court of competent jurisdiction that the Trustee was
          negligent in ascertaining the pertinent facts.

                  (3) The Trustee shall not be liable with respect to any action
          it takes or omits to take in good faith in accordance with a direction
          received by it pursuant to Section 6.05.

                  (d) No provision of this Indenture shall require the Trustee
to expend or risk its own funds or otherwise incur any liability, financial or
otherwise, in the performance of any of its duties hereunder or


<PAGE>
                                      -65-


to take or omit to take any action under this Indenture or take any action at
the request or direction of Holders if it shall have reasonable grounds for
believing that repayment of such funds is not assured to it or it does not
receive from such Holders an indemnity satisfactory to it against such risk,
liability, loss, fee or expense which might be incurred by it in compliance with
such request or direction.

                  (e) Whether or not herein expressly provided, every provision
of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b), (c) and (d) of this Section 7.01.

                  (f) The Trustee shall not be liable for interest on any money
or assets received by it except as the Trustee may agree in writing with the
Company. Assets held in trust by the Trustee need not be segregated from other
assets except to the extent required by law.

Section 7.02.     RIGHTS OF TRUSTEE.

                  Subject to Section 7.01:

                  (a) The Trustee may conclusively rely and shall be fully
         protected in acting or refraining from acting upon any officers'
         certificate, opinion of counsel, resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent, order
         or document reasonably believed by it to be genuine and to have been
         signed or presented by the proper Person. The Trustee need not
         investigate any fact or matter stated in the document.

                  (b) Before the Trustee acts or refrains from acting with
         respect to any matters contemplated by this Indenture or the Notes it
         may consult with counsel and may require an Officers' Certificate or an
         Opinion of Counsel, or both, which shall conform to the provisions of
         Section 12.05. The Trustee shall be fully protected and shall not be
         liable for any action it takes or omits to take in good faith in
         reliance on such certificate or opinion.

                  (c) The Trustee may act through attorneys and agents and shall
         not be responsible for the misconduct or negligence of any attorney or
         agent so long as the appointment of such attorney or agent was made
         with due care.

                  (d) The Trustee shall not be liable for any action it takes or
         omits to take in good faith which it reasonably believes to be
         authorized or within its rights or powers conferred on it by this
         Indenture.

                  (e) The Trustee may consult with counsel of its selection, and
         the advice or opinion of such counsel shall be full and complete
         authorization and protection from liability in respect of any action
         taken, omitted or suffered by it hereunder in good faith and in
         accordance with the advice or opinion of such counsel.

                  (f) In no event shall the Trustee be liable for the selection
         of investments or for investment losses thereon. The Trustee shall have
         no liability in respect of losses incurred as a result of the
         liquidation of any investment prior to its stated maturity or the
         failure of the Company to provide timely written instructions.

Section 7.03.     INDIVIDUAL RIGHTS OF TRUSTEE.

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Notes and may make loans to, accept deposits from,
perform services for or otherwise deal with the Company, or any


<PAGE>
                                      -66-


Affiliates thereof, with the same rights it would have if it were not Trustee.
Any Agent may do the same with like rights. The Trustee, however, shall be
subject to Sections 7.10 and 7.11.

Section 7.04.     TRUSTEE'S DISCLAIMER.

                  The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture or the Notes, it
shall not be accountable for the Company's use of the proceeds from the sale of
Notes or any money paid to the Company pursuant to the terms of this Indenture
and it shall not be responsible for any statement of the Company in this
Indenture or the Notes other than the Trustee's certificate of authentication.

Section 7.05.     NOTICE OF DEFAULTS.

                  If a Default or an Event of Default occurs and is continuing
and if a Responsible Officer of the Trustee has actual knowledge of such Default
or Event of Default, the Trustee shall mail to each Noteholder notice of the
uncured Default or Event of Default within 30 days after such Default or Event
of Default occurs. Except in the case of a Default or an Event of Default in
payment of principal of, premium or interest on, any Note, including an
accelerated payment and the failure to make payment on the Change of Control
Payment Date pursuant to a Change of Control Offer or on the Excess Proceeds
Payment Date pursuant to an Excess Proceeds Offer and, except in the case of a
failure to comply with Article 5. This Section 7.05 shall be in lieu of the
proviso to Section 315(b) of the TIA, and such proviso of Section 315(b) of the
TIA is hereby expressly excluded from this Indenture and the Notes, as permitted
by the TIA.

Section 7.06.     REPORTS BY TRUSTEE TO HOLDERS.

                  If required by TIA Section 313(a), within 60 days after May 15
of any year, commencing the May 15 following the date of this Indenture, the
Trustee shall mail to each Noteholder a brief report dated as of such May 15
that complies with TIA Section 313(a). The Trustee also shall comply with TIA
Section 313(b), (c) and (d).

                  Reports pursuant to this Section 7.06 shall be transmitted by
mail:

                  (1) to all registered Holders, as the names and addresses of
         such Holders appear on the Registrar's books; and

                  (2) to such Holder as have, within the two years preceding
         such transmission, filed their names and addresses with the Trustee for
         that purpose.

                  A copy of each report at the time of its mailing to Holders
shall be filed with the Commission and each stock exchange, if any, on which the
Notes are listed. The Company shall promptly notify the Trustee when the Notes
are listed on any stock exchange or of any delisting thereof.

Section 7.07.     COMPENSATION AND INDEMNITY.

                  The Company shall pay to the Trustee from time to time such
compensation as shall be agreed in writing between the Company and the Trustee
for the Trustee's services. The Trustee's compensation shall not be limited by
any law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee upon request for all reasonable fees, disbursements,
advances and expenses, including out-of-pocket expenses incurred or made by it
in connection with the performance of its duties under this Indenture (except
for such


<PAGE>
                                      -67-


expenses as may be attributable to its negligence, bad faith or willful
misconduct as conclusively determined by a court of competent jurisdiction) or
in connection with the collection of any funds. Such expenses shall include the
reasonable fees and expenses of the Trustee's agents, counsel and others not
regularly in its employ.

                  The Company shall indemnify each of the Trustee (in its
capacity as Trustee) and its agents, employees, stockholders and directors and
officers for, and hold them harmless against, any loss, claim, damage, injury,
liability or expense incurred by them except for such actions to the extent
caused by any negligence, bad faith or willful misconduct on their part,
directly or indirectly arising out of or in connection with the administration
of this trust, including the reasonable costs and expenses of defending
themselves against any claim or liability in connection with the exercise or
performance of any of their rights, powers or duties hereunder. The Trustee
shall notify the Company promptly, in writing, of any claim asserted against the
Trustee for which it may seek indemnity. At the Trustee's discretion, the
Company shall defend the claim and the Trustee shall cooperate and may
participate in the defense; PROVIDED that any settlement of a claim shall be
approved in writing by the Trustee. The Company need not pay for any settlement
made without its written consent, which consent shall not be unreasonably
withheld. The Company need not reimburse any expense or indemnify against any
loss or liability to the extent incurred by the Trustee through its negligence,
bad faith or willful misconduct as conclusively determined by a court of
competent jurisdiction.

                  To secure the Company's payment obligations in this Section
7.07, the Trustee shall have a lien prior to the Notes on all assets or money
held or collected by the Trustee, in its capacity as Trustee, except assets or
money held in trust to pay principal of, premium, if any, or interest on
particular Notes.

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(f) or (g) occurs, such expenses and
the compensation for such services are intended to constitute expenses of
administration under any Bankruptcy Law.

                  The obligation of the Company under this Section 7.07 shall
survive the resignation or removal of the Trustee and the satisfaction and
discharge of this Indenture.

Section 7.08.     REPLACEMENT OF TRUSTEE.

                  The Trustee may resign at any time by so notifying the Company
in writing. The Holders of a majority in aggregate principal amount of the
outstanding Notes may remove the Trustee by so notifying the Trustee and the
Company in writing and may appoint a successor Trustee with the Company's
consent, such consent not to be unreasonably withheld. The Company may remove
the Trustee at its election if:

                  (a)      the Trustee fails to comply with Section 7.10;

                  (b)      the Trustee is adjudged a bankrupt or an insolvent;

                  (c)      a receiver or other public officer takes charge of
         the Trustee or its property; or

                  (d)      the Trustee otherwise becomes incapable of acting.

                  If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason (the Trustee in such event being referred
to herein as the retiring Trustee), the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the
Holders of a majority in aggregate principal amount of the outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.


<PAGE>
                                      -68-


                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that,
the retiring Trustee shall transfer, after payment of all sums then owing to the
Trustee pursuant to Section 7.07, all property held by it as Trustee to the
successor Trustee, subject to the lien provided in Section 7.07, the resignation
or removal of the retiring Trustee shall become effective, and the successor
Trustee shall have the rights, powers and duties of the Trustee under this
Indenture. A successor Trustee shall mail notice of its succession to each
Noteholder.

                  If a successor Trustee does not take office within 60 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company or the Holders of at least 10% in aggregate principal amount of the
outstanding Notes may petition, at the expense of the Company, any court of
competent jurisdiction for the appointment of a successor Trustee.

                  If the Trustee fails to comply with Section 7.10, any
Noteholder may petition any court of competent jurisdiction for the removal of
the Trustee and the appointment of a successor Trustee.

                  Notwithstanding replacement of the Trustee pursuant to this
Section 7.08, the Company's obligations under Section 7.07 shall continue for
the benefit of the retiring Trustee.

Section 7.09.     SUCCESSOR TRUSTEE BY CONSOLIDATION, MERGER OR CONVERSION.

                  If the Trustee consolidates with, merges or converts into, or

corporation, subject to this Article 7, the successor corporation without any
further act shall (if it is otherwise eligible hereunder) be the successor
Trustee.

Section 7.10.     ELIGIBILITY; DISQUALIFICATION.

                  This Indenture shall always have a Trustee which shall be

Trustee shall have a combined capital and surplus of at least $100,000,000 as
set forth in its most recent published annual report of condition. If the
Trustee has or shall acquire any "conflicting interest" within the meaning of
TIA Section 310(b), the Trustee and the Company shall comply with the provisions
of TIA Section 310(b); PROVIDED, HOWEVER, that there shall be excluded from the
operation of TIA Section 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of
the Company are outstanding if the requirements for such exclusion set forth in
TIA Section 310(b)(1) are met. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 7.10, the Trustee

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

Section 8.01.     WITHOUT CONSENT OF HOLDERS.

                  The Company and the Guarantors, when authorized by a Board
Resolution, and the Trustee may amend or supplement this Indenture, the Notes or
the Guarantees without notice to or consent of any Noteholder:

                  (1) to cure any ambiguity, defect or inconsistency; PROVIDED
         that such amendment or supplement does not, in the opinion of the
         Trustee, adversely affect the rights of any Holder in any material
         respect;

                  (2) to provide for uncertificated Notes in addition to or in
         place of Certificated Notes;

                  (3)  to comply with Article 5;

                  (4) to comply with any requirements of the Commission in order
         to effect or maintain the qualification of this Indenture under the
         TIA;

                  (5) to make any change that would provide any additional
benefit or rights to the Holders;

                  (6) to make any other change that does not adversely affect
         the rights of any Holder under this Indenture;

                  (7) to add to the covenants of the Company or a Guarantor for
         the benefit of the Holders, or to surrender any right or power herein
         conferred upon the Company or any Guarantor;

                  (8)  to secure the Notes pursuant to the requirements of
         Section 4.15 or otherwise; and

                  (9) to reflect the release of a Guarantor from its obligations
         with respect to its Guarantee pursuant to Section 11.05 or to add a
         Guarantor pursuant to Section 4.24.

Section 8.02.     WITH CONSENT OF HOLDERS.

                  Subject to Section 6.07, the Company and the Guarantors, when
each is authorized by a Board Resolution, and the Trustee may amend or
supplement this Indenture, the Notes or the Guarantees with the written consent
of the Holders of at least a majority in aggregate principal amount of the
outstanding Notes. Subject to Section 6.07, the Holders of a majority in
aggregate principal amount of the outstanding Notes may waive compliance by the
Company or any Guarantor with any provision of this Indenture, the Notes or the
Guarantees. However, without the consent of each Noteholder affected, an
amendment, supplement or waiver, including a waiver pursuant to Section 6.04,
may not:

                  (1) reduce the amount of Notes whose Holders must consent to
         an amendment, supplement or waiver, or consent to take any action under
         this Indenture or the Notes;


<PAGE>
                                      -70-


                  (2) reduce the rate of or change the time for payment of
         interest, including defaulted interest, on any Note;

                  (3) reduce the principal of or premium on or change the stated
         maturity of any Note or change the date on which any Notes may be
         subject to redemption or repurchase or reduce the redemption or
         repurchase price therefor;

                  (4) make any Note payable in money other than that stated in
         the Note or change the place of payment from New York, New York;

                  (5) waive a Default in the payment of the principal of,
         interest on, or redemption payment with respect to, any Note;

                  (6)  make any changes in Sections 6.04 or 6.07 or this
         sentence of Section 8.02;

                  (7) modify or change any provision of this Indenture or the
         related definitions affecting the subordination or ranking of the Notes
         or any Guarantee in a manner that adversely affects the Holders;

                  (8) amend, change or modify in any material respect the
         obligation of the Company to make and consummate a Change of Control
         Offer in the event of a Change of Control, make and consummate an
         Excess Proceeds Offer with respect to any Asset Sale that has been
         consummated or modify any of the provisions or definitions with respect
         thereto; or

                  (9) release any Guarantor from any of its obligations under
         its Guarantee or this Indenture otherwise than in accordance with the
         terms of this Indenture.

                  In addition, without the consent of the Holders of 90% in
principal amount of the Notes then outstanding, no amendment may release any
Guarantor from any of its obligations under its Guarantee or this Indenture
otherwise than in accordance with the terms of this Indenture.

                  After an amendment, supplement or waiver under this Section
8.02 becomes effective, the Company shall mail to the Holders a notice briefly
describing the amendment, supplement or waiver. Any failure of the Company to
mail such notice, or any defect therein, shall not, however, in any way impair
or affect the validity of any such supplemental indenture.

                  Upon the request of the Company, accompanied by a Board
Resolution authorizing the execution of any such supplemental indenture, and
upon the receipt by the Trustee of evidence satisfactory to the Trustee of the
consent of the Holders as aforesaid and upon receipt by the Trustee of the
documents described in Section 8.06, the Trustee shall join with the Company and
the Guarantors in the execution of such supplemental indenture unless such
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture, in which case the Trustee may in its discretion, but shall
not be obligated to, enter into such supplemental indenture.

                  It shall not be necessary for the consent of the Holders under
this Section 8.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

                                      -71-


Section 8.03.     COMPLIANCE WITH TIA.

                  Every amendment to or supplement of this Indenture, the Notes
or the Guarantees shall comply with the TIA as then in effect.

Section 8.04.     REVOCATION AND EFFECT OF CONSENTS.

                  Until an amendment, waiver or supplement becomes effective, a
consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as
the consenting Holder's Note, even if notation of the consent is not made on any
Note. Subject to the following paragraph, any such Holder or subsequent Holder
may revoke the consent as to such Holder's Note or portion of such Note by
written notice to the Trustee or the Company received before the date on which
the Trustee receives an Officers' Certificate certifying that the Holders of the
requisite principal amount of Notes have consented (and not theretofore revoked
such consent) to the amendment, supplement or waiver.

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders entitled to consent to any
amendment, supplement or waiver. If a record date is fixed, then notwithstanding
the last sentence of the immediately preceding paragraph, those Persons who were
Holders at such record date (or their duly designated proxies), and only those
Persons, shall be entitled to revoke any consent previously given, whether or
not such Persons continue to be Holders after such record date. No such consent
shall be valid or effective for more than 90 days after such record date.

                  After an amendment, supplement or waiver becomes effective, it
shall bind every Noteholder, unless it makes a change described in any of
clauses (1) through (8) of Section 8.02, in which case, the amendment,
supplement or waiver shall bind only each Holder of a Note who has consented to
it and every subsequent Holder of a Note or portion of a Note that evidences the
same debt as the consenting Holder's Note; PROVIDED that any such waiver shall
not impair or affect the right of any Holder to receive payment of principal of
and interest on a Note, on or after the respective due dates expressed in such
Note, or to bring suit for the enforcement of any such payment on or after such
respective dates without the consent of such Holder.

Section 8.05.     NOTATION ON OR EXCHANGE OF NOTES.

                  If an amendment, supplement, or waiver changes the terms of a
Note, the Trustee may request the Holder to deliver it to the Trustee. In such
case, the Trustee shall place an appropriate notation on the Note about the
changed terms and return it to the Holder. Alternatively, if the Company or the
Trustee so determine, in exchange for the Note the Company shall issue and the
Trustee shall authenticate a new Note that reflects the changed terms. Failure
to make the appropriate notation or issue a new Note shall not affect the
validity and effect of such amendment supplement or waiver.

Section 8.06.     TRUSTEE TO SIGN AMENDMENTS, ETC.

                  The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
any amendment, supplement or waiver authorized pursuant to this Article 8 is
authorized or permitted by this Indenture that all requisite consents have been
obtained or that no consents are required and that such amendment, supplement or
waiver constitutes the legal, valid and binding obligation of the Company and
any Guarantors, enforceable in accordance with its terms (subject to customary
exceptions). The Trustee may, but shall not be obligated to, execute any such
amendment, supplement or waiver which materially adversely affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise.

expense of the Company, shall execute proper instruments acknowledging

         than (i) Notes which have been destroyed, lost or stolen and which have
         been replaced or paid as provided in Section 2.07 and (ii) Notes for
         whose payment money has theretofore been deposited in trust or
         segregated and held in trust by the Company and thereafter repaid to

         Trustee for cancellation; or

                  (b) (i) either (A) pursuant to Article 3, the Company shall
         have given written notice to the Trustee and mailed a notice of
         redemption to each Holder of the redemption of all of the Notes under
         arrangements satisfactory to the Trustee for the giving of such notice
         or (B) all Notes not theretofore delivered to the Trustee for
         cancellation have become due and payable; (ii) the Company has
         irrevocably deposited or caused to be deposited with the Trustee in
         trust for the purpose an amount of U.S. legal tender and/or U.S.
         Government Obligations sufficient to pay and discharge the entire
         Indebtedness on such Notes not theretofore delivered to the Trustee for
         cancellation, for the principal of, premium, if any, and interest to
         the date of such deposit; (iii) no Default or Event of Default with
         respect to this Indenture or the Notes shall have occurred and be
         continuing on the date of such deposit or shall occur as a result of
         such deposit and such deposit will not result in a breach or violation
         of, or constitute a default under, any other instrument to which the
         Company is a party or by which it is bound; (iv) the Company has paid
         or caused to be paid all other sums payable hereunder by the Company;
         (v) the Company has delivered to the Trustee (A) irrevocable
         instructions to apply the deposited money toward payment of the Notes
         at the maturity thereof, and (B) an Officers' Certificate and an
         Opinion of Counsel each stating that all conditions precedent herein
         provided for relating to the satisfaction and discharge of this
         Indenture have been complied with and that such satisfaction and
         discharge does not result in a default under the Senior Credit Facility
         (if then in effect) or any other agreement or instrument then known to
         such counsel which binds or affects the Company; and (vi) that from and
         after the time of deposit, the money deposited shall not be subject to
         the rights of holders of Senior Indebtedness pursuant to the provisions
         of Article 10 or to the rights of holders of Guarantor Senior
         Indebtedness pursuant to the provisions of Article 11.

                  Notwithstanding the foregoing paragraph, the Company's
obligations in Article 2 and Sections 4.01, 4.07, 7.07, 9.05 and 9.06 shall
survive until the Notes are no longer outstanding pursuant to the last paragraph
of Section 2.08. After the Notes are no longer outstanding, the Company's
obligations in Sections 7.07 and 9.06 shall survive.

                  After such delivery or irrevocable deposit, the Trustee upon
request shall acknowledge in writing the discharge of the Company's and each
Guarantor's obligations under the Notes, the Guarantees and this Indenture
except for those surviving obligations specified above.

Section 9.02. LEGAL DEFEASANCE.

                  (a) The Company and the Guarantors may, at the option of the
Company, by a Board Resolution, at any time, elect to have this Section be

conditions set forth in Section 9.04.

                  (b) Upon the Company's exercise under paragraph (a) hereof of
the option applicable to this paragraph (b), the Company and each Guarantor
shall, subject to the satisfaction of the conditions set forth in Section 9.04,
be deemed to have been discharged from their respective obligations with respect
to all outstanding Notes and any Guarantees on the date the conditions set forth
below are satisfied (hereinafter, "LEGAL DEFEASANCE"). For this purpose, Legal
Defeasance means that the Company and each Guarantor shall be deemed to have
paid and discharged the entire Indebtedness represented by the outstanding Notes
and any Guarantees, which shall thereafter be deemed to be "outstanding" only
for the purposes of Section 9.05 and the other Sections of this Indenture
referred to in (i) and (ii) below, and to have satisfied all their other
respective obligations under such Notes and this Indenture (and the Trustee, on
written demand of and at the expense of the Company, shall execute proper
instruments acknowledging the same), and Holders and any amounts deposited under
Section 9.04 shall cease to be subject to any obligations to, or the rights of,
any holder of Senior Indebtedness under Article 10 or otherwise or any holder of
Guarantor Senior Indebtedness under Article 11 or otherwise, except for the
following provisions, which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of outstanding Notes to receive
solely from the trust fund described in Section 9.05, and as more fully set
forth in such Section, payments in respect of the principal of, premium, if any,
and interest on such Notes when such payments are due, (ii) the Company's
obligations with respect to such Notes under Article 2 and Section 4.07, (iii)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
the Company's obligations in connection therewith and (iv) this Article 9.
Subject to compliance with this Article 9, the Company may exercise its option
under this Section 9.02 notwithstanding the prior exercise of its option under
Section 9.03 below with respect to the Notes.

Section 9.03.     COVENANT DEFEASANCE.

                  (a) The Company may, at its option by a resolution of the
Board of Directors of the Company, at any time, elect to have this Section be
applied to all outstanding Notes upon compliance with the conditions set forth
in Section 9.04.

                  (b) Upon the Company's exercise under paragraph (a) hereof of
the option applicable to this paragraph (b), the Company and each Guarantor
shall, subject to the satisfaction of the conditions set forth in Section 9.04,
be released from their respective obligations under the covenants contained in
Sections 4.05, 4.08, 4.09 and 4.10 through 4.26, inclusive, and Article 5 with
respect to the outstanding Notes and any Guarantees on and after the date the
conditions set forth below are satisfied (hereinafter, "COVENANT DEFEASANCE"),
and the Notes and any Guarantees shall thereafter be deemed not "outstanding"
for the purposes of any direction, waiver, consent or declaration or act of
Holders (and the consequences of any thereof) in connection with such covenants,
but shall continue to be deemed "outstanding" for all other purposes hereunder
and Holders and any amounts deposited under Section 9.04 shall cease to be
subject to any obligations to, or the rights of, any holder of Senior
Indebtedness under Article 10 or otherwise or any holder of Guarantor Senior
Indebtedness under Article 11 or otherwise. For this purpose, such Covenant
Defeasance means that, with respect to the outstanding Notes and the Guarantees,
the Company and each Guarantor may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event or Default under Section
6.01(c), but, except as specified above, the remainder of this Indenture, such
Notes and


<PAGE>
                                      -74-


any Guarantees shall be unaffected thereby. In addition, upon the Company's
exercise under paragraph (a) above of the option applicable to this paragraph
(b), subject to the satisfaction of the conditions set forth in Section 9.04,
Sections 6.01(c), 6.01(d) and 6.01(e) shall not constitute Events of Default.

Section 9.04.     CONDITIONS TO LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

                  The following shall be the conditions to the application of
either Section 9.02 or 9.03 to the outstanding Notes and any Guarantees:

                  In order to exercise either Legal Defeasance or Covenant
Defeasance:

                  (a) the Company must irrevocably deposit or cause to be
         irrevocably deposited with the Trustee, in trust, for the benefit of
         the Holders, U.S. legal tender or U.S. Government Obligations, or a
         combination thereof, in such amounts as will be sufficient, in the
         opinion of a nationally recognized firm of independent public
         accountants, to pay the principal of, premium, if any, and interest on
         the Notes on the scheduled due dates therefore or on the applicable
         Redemption Date, as the case may be, PROVIDED that the Trustee shall
         have received an irrevocable written order from the Company instructing
         the Trustee to apply such U.S. legal tender or the proceeds of such
         U.S. government obligations to said payments with respect to the Notes;

                  (b) in the case of an election under Section 9.02, the Company
         shall have delivered to the Trustee an Opinion of Counsel reasonably
         acceptable to the Trustee confirming that (i) the Company has received
         from, or there has been published by, the Internal Revenue Service a
         ruling or (ii) since the date of this Indenture, there has been a
         change in the applicable federal income tax law, in either case to the
         effect that, and based thereon such Opinion of Counsel shall confirm
         that, the Holders will not recognize income, gain or loss for federal
         income tax purposes as a result of such Legal Defeasance and will be
         subject to federal income tax on the same amounts, in the same manner
         and at the same times as would have been the case if such Legal
         Defeasance had not occurred;

                  (c) in the case of an election under Section 9.03, the Company
         shall have delivered to the Trustee an Opinion of Counsel confirming
         that the Holders will not recognize income, gain or loss for federal
         income tax purposes as a result of such Covenant Defeasance and will be
         subject to federal income tax on the same amounts, in the same manner
         and at the same times as would have been the case if such Covenant
         Defeasance had not occurred;

                  (d) no Default or Event of Default shall have occurred and be
         continuing on the date of such deposit or insofar as Sections 6.01(f)
         and 6.01(g) are concerned, at any time in the period ending on the 91st
         day after the date of such deposit;

                  (e) such Legal Defeasance or Covenant Defeasance shall not
         result in a breach or violation of, or constitute a default under, this
         Indenture or any other material agreement or instrument to which the
         Company or any of its Subsidiaries is a party or by which the Company
         or any of its Subsidiaries is bound;

                  (f) the Company shall have delivered to the Trustee an
         Officers' Certificate stating that the deposit was not made by the
         Company with the intent of preferring the Holders over any other
         creditors of the Company or with the intent of defeating, hindering,
         delaying or defrauding any other creditors of the Company;


<PAGE>
                                      -75-


                  (g) the Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent provided for or relating to the Legal Defeasance
         or the Covenant Defeasance have been complied with;

                  (h) the Company shall have delivered to the Trustee an Opinion
         of Counsel to the effect that (i) the trust funds will not be subject
         to any rights of any holders of Senior Indebtedness or Guarantor Senior
         Indebtedness, including, without limitation, those arising hereunder,
         and (ii) assuming no intervening event of the type described in
         Sections 6.01(f) and 6.01(g) and that no Holder is an insider of the
         Company, after the 91st day following the deposit or, if longer, ending
         on the day following the expiration of the longest preference period
         under any Bankruptcy Law (it being understood that this condition
         should not be deemed to be satisfied until the expiration of such
         period) the trust funds will not be subject to the effect of any
         applicable Bankruptcy Law;

                  (i) such Legal Defeasance or Covenant Defeasance shall not
         cause the Trustee to have a conflicting interest for purposes of the
         TIA with respect to any securities of the Company; and

                  (j) the Company shall have delivered to the Trustee an Opinion
         of Counsel stating that, as a result of such Legal Defeasance or
         Covenant Defeasance, neither the trust nor the Trustee will be required
         to register as an investment company under the Investment Company Act
         of 1940, as amended.

Section 9.05.     APPLICATION OF TRUST MONEY.

                  All money and U.S. Government Obligations (including the
proceeds thereof) deposited with the Trustee pursuant to Section 9.01 or 9.04 in
respect of the outstanding Notes shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Notes and this Indenture, to
the payment, either directly or through any Paying Agent as the Trustee may
determine, to the Holders of such Notes, of all sums due and to become due
thereon in respect of principal, premium, if any, and accrued interest, but such
money need not be segregated from other funds except to the extent required by
law.

                  The Company shall pay and indemnify the Trustee and its
officers, directors, agents and employees against any tax, fee or other charge
imposed on or assessed against any U.S. Government Obligations deposited
pursuant to Section 9.01 or 9.04 or the principal, premium, if any, and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of the outstanding Notes.

                  Anything in this Article 9 to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon a written
request of the Company in the form of an Officers' Certificate any money or U.S.
Government Obligations held by it as provided in Section 9.01 or 9.04 which, in
the opinion of a nationally-recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect an equivalent Legal Defeasance or Covenant Defeasance, and thereupon
shall be relieved from all liability with respect to such money.

Section 9.06.     REPAYMENT TO THE COMPANY.

                  Subject to Sections 9.01, 9.02, 9.03, 9.04, 9.05 and 9.07, the
Trustee and the Paying Agent shall promptly pay to the Company upon written
request any excess U.S. legal tender or U.S. Government Obligations held by them
at any time and thereupon shall be relieved from all liability with respect to
such money. The Trustee and the Paying Agent shall pay to the Company upon
written request any money held by them for the


<PAGE>
                                      -76-


payment of principal, premium, if any, or interest that remains unclaimed for
two years; PROVIDED that the Trustee or such Paying Agent, before being required
to make any payment, may at the expense of the Company cause to be published
once in a newspaper of general circulation in the City of New York or mail to
each Holder entitled to such money notice that such money remains unclaimed, and
that after a date specified therein which shall be at least 30 days from the
date of such publication or mailing, any unclaimed balance of such money then
remaining will be repaid to the Company. After payment to the Company, Holders
entitled to such money must look to the Company for payment as general creditors
unless an applicable law designates another Person, and all liability of the
Trustee and such Paying Agent with respect to such money shall cease.

Section 9.07.     REINSTATEMENT.

                  If the Trustee or Paying Agent is unable to apply any U.S.
legal tender or U.S. Government Obligations in accordance with Section 9.01,
9.02 or 9.03 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's and each Guarantor's
obligations under this Indenture, the Notes and the Guarantees shall be revived
and reinstated as though no deposit had occurred pursuant to this Article 9
until such time as the Trustee or Paying Agent is permitted to apply all such
U.S. legal tender or U.S. Government Obligations in accordance with Section
9.01; PROVIDED, HOWEVER, that if the Company or the Guarantors have made any
payment of principal of, premium, if any, or accrued interest on any Notes
because of the reinstatement of their obligations, the Company and each such
Guarantor shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the U.S. legal tender or U.S. Government Obligations
held by the Trustee or Paying Agent.

                                   ARTICLE 10

of all Obligations on the Notes by the Company are hereby expressly made
subordinate and subject in right of payment as provided in this Article 10 to
the prior indefeasible payment in full in cash of all Senior Indebtedness of the
Company, whether outstanding on the Issue Date or thereafter incurred.

                  This Section 10.01 and the following Sections 10.02 through

                                      -77-


bankruptcy, relative to the Company or to its creditors, as such, or to the
Company's assets, whether voluntary or involuntary, or (c) any general
assignment by the Company for the benefit of its creditors or (d) any other
marshalling of assets or liabilities of the Company (except in connection with

following the transfer of all or substantially all of its assets, upon the terms
and conditions permitted under the circumstances described under Section 5.01)
(all of the foregoing events described in clauses (a) through (d) referred to

         entitled to receive payment and satisfaction in full in cash of all
         amounts due on or in respect of all Senior Indebtedness of the Company
         before the Holders are entitled to receive any payment or distribution
         of any kind on account of the Notes (except that the Holders may
         receive payments of amounts previously deposited in trust in accordance
         with the defeasance provisions of this Indenture described under

         entitled but for the provisions of this Article 10 shall be paid by the
         liquidating trustee or agent or other Person making such payment or
         distribution, whether a trustee in bankruptcy, a receiver or
         liquidating trustee or otherwise, directly to the holders of Senior
         Indebtedness or their representative or representatives or to the
         trustee or trustees under any indenture under which any instruments
         evidencing any of such Senior Indebtedness may have been issued,
         ratably according to the aggregate amounts remaining unpaid on account
         of the Senior Indebtedness held or represented by each, to the extent
         necessary to make payment in full in cash of all Senior Indebtedness
         remaining unpaid, after giving effect to any concurrent payment or
         distribution to the holders of such Senior Indebtedness; and

                  (3) in the event that, notwithstanding the foregoing
         provisions of this Section 10.02, the Trustee or any Holder shall have
         received any payment or distribution of assets of the Company of any
         kind or character, whether in cash, property or securities, including,
         without limitation, by way of set-off or otherwise, in respect of the
         principal of, premium, if any, and interest on the Notes before all
         Senior Indebtedness is indefeasibly paid in full, then and in such
         event such payment or distribution shall be paid over or delivered
         forthwith to the trustee in bankruptcy, receiver, liquidating trustee,
         custodian, assignee, agent or other Person making payment or
         distribution of assets of the Company for application to the payment of
         all such Senior Indebtedness remaining unpaid, to the extent necessary

Company with or into, another Person or the liquidation or dissolution of the
Company following the conveyance, transfer or lease of its properties and assets
substantially as an entirety to another Person upon the terms and conditions set
forth in Article 5 shall not be deemed a dissolution, winding-up, liquidation,
reorganization, assignment for the benefit of creditors or marshaling of assets
and liabilities of the Company for the purposes of this Article 10 if the Person
formed by such consolidation or the surviving entity of such merger or the
Person which acquires by conveyance, transfer or lease such properties and
assets substantially as an entirety, as the case may be, shall, as a part of
such consolidation, merger, conveyance, transfer or lease, comply with the

Section 10.03.    SUSPENSION OF PAYMENT WHEN SENIOR INDEBTEDNESS IN DEFAULT.

                  (a) Unless Section 10.02 shall be applicable, upon the
occurrence of a Payment Default on Designated Senior Indebtedness, no payment or
distribution (other than a payment or distribution of amounts previously
deposited in trust in accordance with the defeasance provisions described under
Article 9) of any kind or character (including, without limitation, cash,
property and any payment or distribution which may be payable or deliverable by
reason of the payment of any other indebtedness of the Company being
subordinated to the payment of the Notes by the Company) may be made by or on
behalf of the Company or any Restricted Subsidiary, including, without
limitation, by way of set-off or otherwise, for or on account of the Notes, or
for or on account of the purchase, redemption or other acquisition of any Notes,
and neither the Trustee nor any holder or owner of any Notes shall take or
receive from the Company or any Restricted Subsidiary, directly or indirectly in
any manner, payment in respect of all or any portion of Notes commencing on the
date of receipt by the Trustee of written notice from the representative of the
holders of Designated Senior Indebtedness (the "Representative") of the
occurrence of such Payment Default, and in any such event, such prohibition
shall continue until such Payment Default is cured, waived in writing or
otherwise ceases to exist. At such time as the prohibition set forth in the
preceding sentence shall no longer be in effect, subject to the provisions of
the following paragraph, the Company shall resume making any and all required
payments in respect of the Notes, including any missed payments.

                  (b) Unless Section 10.02 shall be applicable, upon the
occurrence of a Non-Payment Event of Default on Designated Senior Indebtedness,
no payment or distribution (other than a payment or distribution of amounts
previously deposited in trust in accordance with the defeasance provisions
described under Article 9) of any kind or character (including, without
limitation, cash, property and any payment or distribution that may be payable
or deliverable by reason of the payment of any other indebtedness of the Company
being subordinated to the payment of the Notes by the Company) may be made by
the Company or any Restricted Subsidiary, including, without limitation, by way
of set-off or otherwise, for or on account of the Notes, or for or on account of
the purchase, redemption or other acquisition of any Notes, and neither the
Trustee nor any holder or owner of any Notes shall take or receive from the
Company or any Restricted Subsidiary, directly or indirectly in any manner,
payment in respect of all or any portion of the Notes for a period (a "PAYMENT
BLOCKAGE PERIOD") commencing on the date of receipt by the Trustee of written
notice from the Representative of such Non-Payment Event of Default unless and
until (subject to any blockage of payments that may then be in effect under the
preceding paragraph) the earliest of

                  (1) more than 179 days shall have elapsed since receipt of
          such written notice by the Trustee,

                  (2) such Non-Payment Event of Default shall have been cured or
          waived in writing or otherwise shall have ceased to exist or such
          Designated Senior Indebtedness shall have been paid in full, or

                  (3) such Payment Blockage Period shall have been terminated by
          written notice to the Company or the Trustee from such Representative,

after which, in the case of clause (1), (2) or (3), the Company shall resume
making any and all required payments in respect of the Notes, including any
missed payments. Notwithstanding any other provision of this Indenture, in no
event shall a Payment Blockage Period commenced in accordance with the
provisions of this Indenture described in this paragraph extend beyond 179 days
from the date of the receipt by the Trustee of the notice referred to above (the
"INITIAL BLOCKAGE PERIOD"). Any number of additional Payment Blockage Periods
may be commenced during the Initial Blockage Period; PROVIDED, HOWEVER, that no
such additional Payment Blockage Period shall extend beyond the Initial Blockage
Period. After the expiration of the Initial Blockage Period, no


<PAGE>
                                      -79-


Payment Blockage Period may be commenced until at least 180 consecutive days
have elapsed from the last day of the Initial Blockage Period. Notwithstanding
any other provision of this Indenture, no Non-Payment Event of Default with
respect to Designated Senior Indebtedness that existed or was continuing on the
date of the commencement of any Payment Blockage Period initiated by the
Representative shall be, or be made, the basis for the commencement of a second
Payment Blockage Period initiated by the Representative, whether or not within
the Initial Blockage Period, unless such Non-Payment Event of Default shall have
been cured or waived for a period of not less than 90 consecutive days.

                  (c) In the event that, notwithstanding the foregoing, the
Trustee or any holder of Notes receives any payment or distribution of assets of
the Company of any kind, whether in cash, property or securities, including,
without limitation, by way of set-off or otherwise, in respect of the Notes
before all Senior Indebtedness of the Company is paid and satisfied in full in
cash, then such payment or distribution (other than a payment or distribution of
amounts previously deposited in trust in accordance with the defeasance
provisions described under Article 9) will be held by the recipient in trust for
the benefit of holders of Senior Indebtedness and will be immediately paid over
or delivered to the holders of Senior Indebtedness or their representative or
representatives to the extent necessary to make payment in full of all Senior
Indebtedness remaining unpaid, after giving effect to any concurrent payment or
distribution, or provision therefor, to or for the holders of Senior
Indebtedness.

Section 10.04.    TRUSTEE'S RELATION TO SENIOR INDEBTEDNESS.

                  The Trustee and any agent of the Company or the Trustee shall
be entitled to all the rights set forth in this Article 10 with respect to any
Senior Indebtedness which may at any time be held by it in its individual or any
other capacity to the same extent as any other holder of Senior Indebtedness and
nothing in this Indenture shall deprive the Trustee or any such agent of any of
its rights as such holder.

                  With respect to the holders of Senior Indebtedness, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article 10, and no implied
covenants or obligations with respect to the holders of Senior Indebtedness
shall be read into this Indenture against the Trustee. The Trustee shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness and the
Trustee shall not be liable to any holder of Senior Indebtedness if it shall
mistakenly pay over or deliver to Holders, the Company or any other person
moneys or assets to which any holder of Senior Indebtedness shall be entitled by
virtue of this Article 10 or otherwise. Nothing in this Section 10.04 shall
affect the obligation of any other such Person receiving such payment or
distribution from the Trustee or any other Agent to hold such payment for the
benefit of, and to pay such payment over to, the holders of Senior Indebtedness.

Section 10.05.    SUBROGATION.

                  Upon the payment in full of all Senior Indebtedness, the
Holders shall be subrogated to the rights of the holders of such Senior
Indebtedness to receive payments and distributions of cash, property and
securities applicable to the Senior Indebtedness until the principal of,
premium, if any and interest on the Notes shall be paid in full. For purposes of
such subrogation, no payments or distributions to the holders of Senior
Indebtedness of any cash, property or securities to which the Holders or the
Trustee would be entitled except for the provisions of this Article 10, and no
payments pursuant to the provisions of this Article 10 to the holders of Senior
Indebtedness by Holders or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Indebtedness and the Holders, be deemed
to be a payment or distribution by the Company to or on account of the Senior
Indebtedness.


<PAGE>
                                      -80-


                  If any payment or distribution to which the Holders would
otherwise have been entitled but for the provisions of this Article 10 shall
have been applied, pursuant to the provisions of this Article 10, to the payment
of all amounts payable under the Senior Indebtedness of the Company, then and in
such case the Holders shall be entitled to receive from the holders of such
Senior Indebtedness at the time outstanding any payments or distributions
received by such holders of such Senior Indebtedness in excess of the amount
sufficient to pay all amounts payable under or in respect of such Senior
Indebtedness in full in cash.

Section 10.06.    PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

                  The provisions of this Article 10 are and are intended solely
for the purpose of defining the relative rights of the Holders on the one hand
and the holders of Senior Indebtedness on the other hand. Nothing contained in
this Article 10 or elsewhere in this Indenture or in the Notes is intended to or
shall (a) impair, as among the Company, its creditors other than holders of
Senior Indebtedness and the Holders, the obligation of the Company, which is
absolute and unconditional, to pay to the Holders the principal of, premium, if
any, and interest on the Notes as and when the same shall become due and payable
in accordance with their terms; or (b) affect the relative rights against the
Company of the Holders and creditors of the Company other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or any Holder from exercising
all remedies otherwise permitted by applicable law upon a Default or an Event of
Default under this Indenture, subject to the rights, if any, under this Article
10 of the holders of Senior Indebtedness (1) in any case, proceeding,
dissolution, liquidation or other winding-up, assignment for the benefit of
creditors or other marshaling of assets and liabilities of the Company referred
to in Section 10.02, to receive, pursuant to and in accordance with such
section, cash, property and securities otherwise payable or deliverable to the
Trustee or such Holder, or (2) under the conditions specified in Section 10.03,
to prevent any payment prohibited by such section or enforce their rights
pursuant to Section 10.03(c).

                  The failure to make a payment on account of principal of,
premium, if any, or interest on the Notes by reason of any provision of this
Article 10 shall not be construed as preventing the occurrence of a Default or
an Event of Default hereunder.

Section 10.07.    TRUSTEE TO EFFECTUATE SUBORDINATION.

                  Each Holder of a Note by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article 10 and
appoints the Trustee his attorney-in-fact for any and all such purposes,
including, in the event of any dissolution, winding-up, liquidation or
reorganization of the Company whether in bankruptcy, insolvency, receivership
proceedings, or otherwise, the timely filing of a claim for the unpaid balance
of the indebtedness of the Company owing to such Holder in the form required in
such proceedings.

Section 10.08.    NO WAIVER OF SUBORDINATION PROVISIONS.

                  (a) No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act, in good faith, by any such holder,
or by any non-compliance by the Company with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such holder may have
or be otherwise charged with.

                  (b) Without limiting the generality of paragraph (a) of this
Section, the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Trustee or the Holders, without
incurring responsibility to the Holders and without impairing or releasing the
subordination provided


<PAGE>
                                      -81-


in this Article 10 or the obligations hereunder of the Holders to the holders of
Senior Indebtedness, do any one or more of the following: (1) change the manner,
place or terms of payment or extend the time of payment of, or renew or alter,
Senior Indebtedness or any instrument evidencing the same or any agreement under
which Senior Indebtedness is outstanding; (2) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (3) release any Person liable in any manner for the collection or
payment of Senior Indebtedness; and (4) exercise or refrain from exercising any
rights against the Company and any other Person; PROVIDED, HOWEVER, that in no
event shall any such actions limit the right of the Holders to take any action
to accelerate the maturity of the Notes pursuant to Article 6 or to pursue any
rights or remedies hereunder or under applicable laws if the taking of such
action does not otherwise violate the terms of this Indenture.

Section 10.09.    NOTICE TO TRUSTEE.

                  (a) The Company shall give prompt written notice to the
Trustee of any fact known to the Company which would prohibit the making of any
payment to or by the Trustee at its Corporate Trust Office in respect of the
Notes. Notwithstanding the provisions of this Article 10 or any other provision
of this Indenture, the Trustee shall not be charged with knowledge of the
existence of any facts which would prohibit the making of any payment to or by
the Trustee in respect of the Notes, unless and until the Trustee shall have
received written notice thereof from the Company or a holder of Senior
Indebtedness or from any trustee, fiduciary or agent therefor; and, prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
this Section 10.09, shall be entitled in all respects to assume that no such
facts exist; PROVIDED, HOWEVER, that if the Trustee shall not have received the
notice provided for in this Section 10.09 at least two Business Days prior to
the date upon which by the terms hereof any money may become payable for any
purpose under this Indenture (including, without limitation, the payment of the
principal of, premium, if any, or interest on any Note), then, anything herein
contained to the contrary notwithstanding but without limiting the rights and
remedies of the holders of Senior Indebtedness or any trustee, fiduciary or
agent therefor, the Trustee shall have full power and authority to receive such
money and to apply the same to the purpose for which such money was received and
shall not be affected by any notice to the contrary which may be received by it
within two Business Days prior to such date; nor shall the Trustee be charged
with knowledge of the curing of any such default or the elimination of the act
or condition preventing any such payment unless and until the Trustee shall have
received an Officers' Certificate to such effect.

                  (b) In the event that the Trustee determines in good faith
that further evidence is required with respect to the right of any Person as a
holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article 10, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article 10, and if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

Section 10.10.    RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING
                  AGENT.

                  Upon any payment or distribution of assets of the Company
referred to in this Article 10, the Trustee, subject to the provisions of
Section 7.01, and the Holders shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding-up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders, for the purpose of ascertaining the
Persons entitled to participate in such payment or distribution, the holders of
Senior Indebtedness and


<PAGE>
                                      -82-


other Indebtedness of the Company, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article 10.

Section 10.11.    NO SUSPENSION OF REMEDIES.

                  Nothing contained in this Article 10 shall limit the right of
the Trustee or the Holders to take any action to accelerate the maturity of the
Notes pursuant to Article 6 or to pursue any rights or remedies hereunder or
under applicable law, subject to the rights, if any, under this Article 10 of
the holders, from time to time, of Senior Indebtedness.

                               GUARANTEE OF NOTES

Section 11.01.    GUARANTEE.

                  Subject to the provisions of this Article 11, each Guarantor,
by execution of a Guarantee will, jointly and severally unconditionally
guarantee on a senior subordinated basis to each Holder and to the Trustee, on
behalf of the Holders, (i) the due and punctual payment of the principal of, and
premium, if any, and interest on each Note, when and as the same shall become
due and payable, whether at maturity, by acceleration or otherwise, the due and
punctual payment of interest (including Additional Interest, if any) on the
overdue principal of, and premium, if any, and interest on the Notes, to the
extent lawful, and the due and punctual payment of all other Obligations of the
Company to the Holders or the Trustee (including without limitation amounts due
to the Trustee under Section 7.07) all in accordance with the terms of such Note
and this Indenture, and (ii) in the case of any extension of time of payment or
renewal of any Notes or any of such other Obligations, that the same will be
promptly paid in full when due or performed in accordance with the terms of the
extension or renewal, at stated maturity, by acceleration or otherwise. Each
Guarantor, by execution of a Guarantee, will, agree that its obligations
hereunder shall be absolute and unconditional, irrespective of, and shall be
unaffected by, any invalidity, irregularity or unenforceability of any such Note
or this Indenture, any failure to enforce the provisions of any such Note or
this Indenture, any waiver, modification or indulgence granted to the Company
with respect thereto by the Holder of such Note or the Trustee, or any other
circumstances which may otherwise constitute a legal or equitable discharge of a
surety or such Guarantor.

                  Each Guarantor, by execution of a Guarantee, will waive
diligence, presentment, demand for payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest or notice with respect to any such
Note or the Indebtedness evidenced thereby and all demands whatsoever, and will
covenant that the Guarantee will not be discharged as to any such Note except by
payment in full of the principal thereof, premium, if any, and interest thereon
as provided in Section 9.01. Each Guarantor, by execution of a Guarantee, will
further agree that, as between such Guarantor, on the one hand, and the Holders
and the Trustee, on the other hand, (i) the maturity of the Obligations
guaranteed hereby may be accelerated as provided in Article 6 for the purposes
of this Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the Obligations guaranteed hereby,
and (ii) in the event of any declaration of acceleration of such Obligations as
provided in Article 6, such Obligations (whether or not due and payable) shall
forthwith become due and payable by each Guarantor for the purpose of this
Guarantee. In addition, without limiting the foregoing provisions, upon the
effectiveness of an acceleration under Article 6, the Trustee shall promptly
make a demand for payment on the Notes

                                      -83-


under the Guarantee provided for in this Article 11 and not discharged. Failure
to make such a demand shall not affect the validity or enforceability of the
Guarantee upon any Guarantor.

                  A Guarantee shall not be valid or become obligatory for any
purpose with respect to a Note until the certificate of authentication on such
Note shall have been signed by or on behalf of the Trustee.

                  A Guarantee shall remain in full force and effect and continue
to be effective should any petition be filed by or against the Company for
liquidation or reorganization, should the Company become insolvent or make an
assignment for the benefit of creditors or should a receiver or trustee be
appointed for all or any significant part of the Company's assets, and shall, to
the fullest extent permitted by law, continue to be effective or be reinstated,
as the case may be, if at any time payment and performance of the Notes are,
pursuant to applicable law, rescinded or reduced in amount, or must otherwise be
restored or returned by any obligee on the Notes, whether as a "voidable
preference," "fraudulent transfer" or otherwise, all as though such payment or
performance had not been made. In the event that any payment, or any part
thereof, is rescinded, reduced, restored or returned, the Notes shall, to the
fullest extent permitted by law, be reinstated and deemed reduced only by such
amount paid and not so rescinded, reduced, restored or returned.

                  No stockholder, member, officer, director, employee or
incorporator, past, present or future, of any Guarantor, as such, shall have any
personal liability under this Guarantee by reason of his, her or its status as
such stockholder, member, officer, director, employee or incorporator.

                  A Guarantor, by execution of a Guarantee, will have the right
to seek contribution from any non-paying Guarantor so long as the exercise of
such right does not impair the rights of the Holders under such Guarantee.

Section 11.02.    EXECUTION AND DELIVERY OF GUARANTEE.

                  A Guarantee shall be executed by either manual or facsimile
signature (promptly followed by the original signature page) of an Officer or an
Officer of a general partner, as the case may be, of such Guarantor.

                  If an officer of a Guarantor whose signature is on the
Guarantee no longer holds that office, such Guarantor's Guarantee shall be valid
nevertheless.

Section 11.03.    LIMITATION OF GUARANTEE.

                  Each Guarantor, and by its acceptance hereof each Holder and
the Trustee, hereby confirms that it is the intention of all such parties that
the Guarantee does not constitute a fraudulent transfer or conveyance for
purposes of Title 11 of the United States Code, as amended, the Uniform
Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar
U.S. Federal or state law. To effectuate the foregoing intention, each Holder,
the Trustee and each Guarantor hereby irrevocably agree that the obligations of
a Guarantor under its Guarantee shall be limited to the maximum amount as will,
after giving effect to all other contingent and fixed liabilities of such
Guarantor, and after giving effect to any collections from or payments made by
or on behalf of such Guarantor in respect of the obligations of such Guarantor
pursuant to this Article 11, result in the obligations of such Guarantor not
constituting such a fraudulent transfer or conveyance.

Section 11.04.    ADDITIONAL GUARANTORS.

                  Any Person may become a Guarantor by executing and delivering
to the Trustee (a) a supplemental indenture in form and substance satisfactory
to the Trustee, which subjects such Person to the provisions of this Indenture
as a Guarantor, and (b) an Opinion of Counsel to the effect that such
supplemental indenture has been duly authorized and executed by such Person and
constitutes the legal, valid, binding and enforceable obligation of such Person
(subject to such customary exceptions concerning fraudulent conveyance laws,
creditors' rights and equitable principles as may be acceptable to the Trustee
in its discretion).

Section 11.05.    RELEASE OF GUARANTOR.

                  A Guarantor shall be released from all of its obligations
under its Guarantee if:

                  (i) the Guarantor has sold all or substantially all of its
         assets or the Company and the Restricted Subsidiaries have sold all of
         the Capital Stock of the Guarantor owned by them, in each case in a
         transaction in compliance with the terms of this Indenture (including
         Sections 4.13, 4.17, 4.24 and 5.01);

                  (ii) the Guarantor merges with or into or consolidates with,
         or transfers all or substantially all of its assets to, the Company or
         another Guarantor in a transaction in compliance with the terms of this
         Indenture (including Section 5.01); or

                  (iii) the Guarantor is designated an Unrestricted Subsidiary
         in compliance with the terms of this Indenture (including Section
         4.11);

and in each such case, such Guarantor has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to such transactions have been complied
with and that such release is authorized and permitted hereunder.

                  The Trustee shall execute any documents reasonably requested
by the Company or a Guarantor in order to evidence the release of such Guarantor
from its obligations under its Guarantee endorsed on the Notes and under this
Article 11.

Section 11.06.    SUBORDINATION OF SUBROGATION AND OTHER RIGHTS; SUBROGATION.

                  Each Guarantor hereby agrees that any claim against the
Company that arises from the payment, performance or enforcement of such
Guarantor's obligations under the Guarantee or this Indenture, including,
without limitation, any right of subrogation, shall be subject and subordinate
to, and no payment with respect to any such claim of such Guarantor shall be
made before, the payment in full in cash of all outstanding Senior Indebtedness
and Guarantor Senior Indebtedness in accordance with the provisions provided
therefor in this Indenture.

Section 11.07.  GUARANTEE OBLIGATIONS SUBORDINATED TO GUARANTOR SENIOR
                INDEBTEDNESS.

                  Each Guarantor, by execution of a Guarantee, will covenant and
agree, and each Holder, by its acceptance thereof, will likewise covenant and
agree, that to the extent and in the manner hereinafter set forth in this
Article 11, the Indebtedness represented by the Guarantee and the payment of the
principal of, premium, if any, and interest on the Notes pursuant to the
Guarantee by such Guarantor are hereby expressly made subordi-

<PAGE>
                                      -85-


nate and subject in right of payment as provided in this Article 11 to the prior
indefeasible payment and satisfaction in full in cash of all existing and future
Guarantor Senior Indebtedness of such Guarantor.

                  This Section 11.07 and the following Sections 11.08 through
11.16 shall constitute a continuing offer to all Persons who, in reliance upon
such provisions, become holders of or continue to hold Guarantor Senior
Indebtedness of any Guarantor; and such provisions are made for the benefit of
the holders of Guarantor Senior Indebtedness of each Guarantor; and such holders
are made obligees hereunder and they or each of them may enforce such
provisions.

Section 11.08. PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC., OF A GUARANTOR.

                  In the event of:

               (1)  any insolvency or bankruptcy case or proceeding, or any
        receivership, liquidation, arrangement, reorganization or other similar
        case or proceeding in connection therewith, relative to a Guarantor or
        to its creditors, as such, or to its assets, whether voluntary or
        involuntary; or

               (2)  any liquidation, dissolution or other winding-up or other
        similar case or proceeding in connection therewith whether or not
        involving insolvency or bankruptcy, relative to a Guarantor or to its
        creditors, as such, or to such Guarantor's assets, whether voluntary or
        involuntary; or

               (3)  any general assignment for the benefit of creditors of a
        Guarantor; or

               (4)  any other marshaling of assets or liabilities of a Guarantor
        (except in connection with the merger or consolidation of a Guarantor or
        its liquidation or dissolution following the transfer of substantially
        all of its assets, upon the terms and conditions permitted under the
        circumstances described under Section 5.01).

(all of the foregoing events described in clauses (1) through (4) referred to
herein individually as a "GUARANTOR BANKRUPTCY PROCEEDING" and collectively as
"GUARANTOR BANKRUPTCY PROCEEDINGS"), the holders of Guarantor Senior
Indebtedness will be entitled to receive payment and satisfaction in full in
cash of all amounts due on or in respect of all Guarantor Senior Indebtedness
before the Holders are entitled to receive or retain any payment or distribution
of any kind on account of the Notes (except that Holders may receive payments of
amounts previously deposited in trust in accordance with the defeasance
provisions of this Indenture described under Article 9).

                Any payment or distribution of assets of a Guarantor of any
kind or character, whether in cash, property or securities, by set-off or
otherwise, to which the Holders or the Trustee would be entitled but for the
provisions of this Article 11 shall be paid by the liquidating trustee or agent
or other Person making such payment or distribution, whether a trustee in
bankruptcy, a receiver or liquidating trustee or otherwise, directly to the
holders of Guarantor Senior Indebtedness or their representative or
representatives or to the trustee or trustees under any indenture under which
any instruments evidencing any of such Guarantor Senior Indebtedness may have
been issued, ratably according to the aggregate amounts remaining unpaid on
account of the Guarantor Senior Indebtedness held or represented by each, to the
extent necessary to make payment in full in cash of all Guarantor Senior
Indebtedness remaining unpaid, after giving effect to any concurrent payment or
distribution to the holders of such Guarantor Senior Indebtedness.

                In the event that, notwithstanding the foregoing, the Trustee
or any Holder receives any payment or distribution of assets of a Guarantor of
any kind, whether in cash, property or securities, including, without
limitation, by way of set-off or otherwise, in respect of the Notes before all
Guarantor Senior Indebtedness of

<PAGE>
                                      -86-


a Guarantor is paid and satisfied in full in cash, then such payment or
distribution will be held by the recipient in trust for the benefit of holders
of Guarantor Senior Indebtedness and will be immediately paid over or delivered
to the holders of Guarantor Senior Indebtedness or their representative or
representatives to the extent necessary to make payment in full of all Guarantor
Senior Indebtedness remaining unpaid, after giving effect to any concurrent
payment or distribution, or provision therefor, to or for the holders of
Guarantor Senior Indebtedness.

                  The consolidation of a Guarantor with, or the merger of a
Guarantor with or into, another Person or the liquidation or dissolution of a
Guarantor following the conveyance, transfer or lease of its properties and
assets substantially as an entirety to another Person upon the terms and
conditions set forth in Article 5 shall not be deemed a dissolution, winding-up,
liquidation, reorganization, assignment for the benefit of creditors or
marshaling of assets and liabilities of a Guarantor for the purposes of this
Article 11 if the Person formed by such consolidation or the surviving entity of
such merger or the Person which acquires by conveyance, transfer or lease such
properties and assets substantially as an entirety, as the case may be, shall,
as a part of such consolidation, merger, conveyance, transfer or lease, comply
with the conditions set forth in Article 5.

Section 11.09.  SUSPENSION OF GUARANTEE OBLIGATIONS WHEN GUARANTOR SENIOR
                INDEBTEDNESS IN DEFAULT.
                ---------------------------------------------------------------
                (a)  Unless Section 11.08 shall be applicable, upon the
occurrence of a Payment Default on Designated Senior Indebtedness, no payment or
distribution (other than a payment or distribution of amounts previously
deposited in trust in accordance with the defeasance provisions described under
Article 9) of any kind or character (including, without limitation, cash,
property and any payment or distribution which may be payable or deliverable by
reason of the payment of any other Indebtedness of such Guarantor being
subordinated to the payment of its Obligations on its Guarantee) may be made by
or on behalf of such Guarantor or any Restricted Subsidiary of such Guarantor,
including, without limitation, by way of set-off or otherwise, for or on account
of its Obligations on its Guarantee or for or on account of the purchase or
redemption or other acquisition of its Obligations under its Guarantee, and
neither the Trustee nor any holder or owner of any Notes shall take or receive
from any Guarantor or any Restricted Subsidiary of such Guarantor, directly or
indirectly in any manner, payment in respect of all or any portion of its
Obligations on its Guarantee commencing on the date of receipt by the Trustee of
written notice from the representative of the holders of Designated Senior
Indebtedness which constitutes Guarantor Senior Indebtedness (the "GUARANTOR
REPRESENTATIVE") of the occurrence of such Payment Default, and in any such
event, such prohibition shall continue until such Payment Default is cured,
waived in writing or otherwise ceases to exist. At such time as the prohibition
set forth in the preceding sentence shall no longer be in effect, subject to the
provisions of the following paragraph, such Guarantor shall resume making any
and all required payments in respect of its Obligations under its Guarantee,
including any missed payments.

                (b)  Unless Section 11.08 shall be applicable, upon the
occurrence of a Non-Payment Event of Default on Designated Senior Indebtedness
which constitutes Guarantor Senior Indebtedness, no payment or distribution
(other than a payment or distribution of amounts previously deposited in trust
in accordance with the defeasance provisions described under Article 9) of any
kind or character (including, without limitation, cash, property and any payment
or distribution which may be payable or deliverable by reason of the payment of
any other Indebtedness of such Guarantor being subordinated to the payment of
its Obligations on its Guarantee) may be made by such Guarantor or any
Restricted Subsidiary of such Guarantor, including, without limitation, by way
of set-off or otherwise, for or on account of its Obligations under its
Guarantee, or for or on account of the purchase or redemption or other
acquisition of its Obligations under its Guarantee, and neither the Trustee nor
any holder or owner of any Notes shall take or receive from such Guarantor or
any Restricted Subsidiary of such Guarantor, directly or indirectly in any
manner, payment in respect of or for any portion of its Obligations under its
Guarantee for a period (a "GUARANTOR PAYMENT BLOCKAGE PERIOD") commencing on the
date of receipt by the Trustee of written notice from the Guarantor
Representative of such Non-Payment Event of Default unless and

<PAGE>
                                      -87-


until (subject to any blockage of payments that may then be in effect under the
preceding paragraph) the earliest of

                      (1) more than 179 days shall have elapsed since receipt of
                  such written notice by the Trustee,

                      (2) such Non-Payment Event of Default shall have been
                  cured or waived in writing or shall have ceased to exist or
                  such Designated Senior Indebtedness which constitutes
                  Guarantor Senior Indebtedness shall have been paid in full or

                      (3) such Guarantor Payment Blockage Period shall have been
                  terminated by written notice to such Guarantor or the Trustee
                  from such Guarantor Representative

after which, in the case of clause (1), (2) or (3), such Guarantor shall resume
making any and all required payments in respect of its Obligations under its
Guarantee, including any missed payments. Notwithstanding any other provision of
this Indenture, in no event shall a Guarantor Payment Blockage Period commenced
in accordance with the provisions of this Section 11.09(b) extend beyond 179
days from the date of the receipt by the Trustee of the notice referred to above
(the "INITIAL GUARANTOR BLOCKAGE PERIOD"). Any number of additional Guarantor
Payment Blockage Periods may be commenced during the Initial Guarantor Blockage
Period; PROVIDED, HOWEVER, that no such additional Guarantor Payment Blockage
Period shall extend beyond the Initial Guarantor Blockage Period. After the
expiration of the Initial Guarantor Blockage Period, no Guarantor Payment
Blockage Period may be commenced until at least 180 consecutive days have
elapsed from the last day of the Initial Guarantor Blockage Period.
Notwithstanding any other provision of this Indenture, no Non-Payment Event of
Default with respect to Designated Senior Indebtedness which constitutes
Guarantor Senior Indebtedness that existed or was continuing on the date of the
commencement of any Guarantor Payment Blockage Period initiated by the Guarantor
Representative shall be, or be made, the basis for the commencement of a second
Guarantor Payment Blockage Period initiated by the Guarantor Representative,
whether or not within the Initial Guarantor Blockage Period, unless such
Non-Payment Event of Default shall have been cured or waived for a period of not
less than 90 consecutive days.

                  (c) In the event that, notwithstanding the foregoing, the
Trustee or the holder of Notes receives any payment or distribution of assets of
a Guarantor of any kind, whether in cash, property or securities, including,
without limitation, by way of set-off or otherwise, in respect of such
Guarantor's Obligations under its Guarantee before all Senior Indebtedness which
constitutes Guarantor Senior Indebtedness is paid and satisfied in full in cash,
then such payment or distribution (other than a payment or distribution of
amounts previously deposited in trust in accordance with the defeasance
provisions described under Article 9) will be held by the recipient in trust for
the benefit of holders of such Senior Indebtedness and will be immediately paid
over or delivered to the holders of such Senior Indebtedness or their
representative or representatives to the extent necessary to make payment in
full of all such Senior Indebtedness remaining unpaid, after giving effect to
any concurrent payment or distribution, or provision therefor, to or for holders
of such Senior Indebtedness.

Section 11.10.    TRUSTEE'S RELATION TO GUARANTOR SENIOR INDEBTEDNESS.

                  The Trustee and any Paying Agent shall be entitled to all the
rights set forth in this Article 11 with respect to any Guarantor Senior
Indebtedness which may at any time be held by it in its individual or any other
capacity to the same extent as any other holder of Guarantor Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee or any
Paying Agent of any of its rights as such holder. Nothing in this Article 11
shall apply to claims of, or payments to, the Trustee for its compensation owing
pursuant to and in accordance with the first sentence of Section 7.07.

<PAGE>
                                      -88-


                  With respect to the holders of Guarantor Senior Indebtedness,
the Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article 11, and no implied
covenants or obligations with respect to the holders of Guarantor Senior
Indebtedness shall be read into this Indenture against the Trustee. The Trustee
shall not be deemed to owe any fiduciary duty to the holders of Guarantor Senior
Indebtedness and the Trustee shall not be liable to any holder of Guarantor
Senior Indebtedness (other than for its willful misconduct or gross negligence)
if it shall in good faith mistakenly pay over or deliver to the Holders, the
Company or any other Person moneys or assets to which any holder of Guarantor
Senior Indebtedness shall be entitled by virtue of this Article 11 or otherwise.
Nothing in this Section 11.10 shall affect the obligation of any other such
Person, the Company, or the Holders to hold such money or assets for the benefit
of, and to pay such money or assets over to, the holders of the Guarantor Senior
Indebtedness or their applicable representative or representatives.

Section 11.11.    SUBROGATION TO RIGHTS OF HOLDERS OF GUARANTOR SENIOR
                  INDEBTEDNESS.

                  Upon the payment in full of all amounts payable under or in
respect of all Guarantor Senior Indebtedness of a Guarantor, the Holders shall
be subrogated to the rights of the holders of such Guarantor Senior Indebtedness
to receive payments and distributions of cash, property and securities of such
Guarantor made on such Guarantor Senior Indebtedness until all amounts due to be
paid under the Guarantee shall be paid in full. For the purposes of such
subrogation, no payments or distributions to holders of Guarantor Senior
Indebtedness of any cash, property or securities to which Holders would be
entitled except for the provisions of this Article 11 and no payments over
pursuant to the provisions of this Article 11 to holders of Guarantor Senior
Indebtedness by Holders, shall, as among each Guarantor, its creditors other
than holders of Guarantor Senior Indebtedness and the Holders, be deemed to be a
payment or distribution by such Guarantor to or on account of such Guarantor
Senior Indebtedness.

                  If any payment or distribution to which the Holders would
otherwise have been entitled but for the provisions of this Article 11 shall
have been applied, pursuant to the provisions of this Article 11, to the payment
of all amounts payable under Guarantor Senior Indebtedness, then and in such
case, the Holders shall be entitled to receive from the holders of such
Guarantor Senior Indebtedness at the time outstanding any payments or
distributions received by such holders of Guarantor Senior Indebtedness in
excess of the amount sufficient to pay all amounts payable under or in respect
of such Guarantor Senior Indebtedness in full in cash.

Section 11.12.    GUARANTEE SUBORDINATION PROVISIONS SOLELY TO DEFINE RELATIVE
                  RIGHTS.

                  The subordination provisions of this Article 11 are and are
intended solely for the purpose of defining the relative rights of the Holders
on the one hand and the holders of Guarantor Senior Indebtedness on the other
hand. Nothing contained in this Article 11 or elsewhere in this Indenture or in
the Notes is intended to or shall (a) impair, as among each Guarantor, its
creditors other than holders of its Guarantor Senior Indebtedness and the
Holders, the obligation of such Guarantor, which is absolute and unconditional,
to make payments to the Holders in respect of its Obligations on its Guarantee
in accordance with its terms; or (b) affect the relative rights against such
Guarantor of the Holders and creditors of such Guarantor other than the holders
of the Guarantor Senior Indebtedness; or (c) prevent any Holder from exercising
all remedies otherwise permitted by applicable law upon a Default or an Event of
Default under this Indenture, subject to the rights, if any, under this Article
11 of the holders of Guarantor Senior Indebtedness (1) in any case, proceeding,
dissolution, liquidation or other winding-up, assignment for the benefit of
creditors or other marshaling of assets and liabilities of any Guarantor
referred to in Section 11.08, to receive, pursuant to and in accordance with
such Section, cash, property and securities otherwise payable or deliverable to
such Holder, or (2) under the conditions specified in Section 11.09, to prevent
any payment prohibited by such Section or enforce their rights pursuant to
Section 11.09(c).

<PAGE>
                                      -89-


                  The failure by any Guarantor to make a payment in respect of
its obligations on its Guarantee by reason of any provision of this Article 11
shall not be construed as preventing the occurrence of a Default or an Event of
Default hereunder.

Section 11.13.    TRUSTEE TO EFFECTUATE SUBORDINATION.

                  Each Holder by his acceptance of a Guarantee agrees to be
bound by such provisions and authorizes and directs the Trustee, on his behalf,
to take such action as may be necessary or appropriate to effectuate the
subordination provisions in this Article 11 and appoints the Trustee his
attorney-in-fact for any and all such purposes, including, in the event of any
Guarantor Bankruptcy Proceeding or other dissolution, winding-up, liquidation or
reorganization of a Guarantor whether in bankruptcy, insolvency, receivership
proceedings, or otherwise, the prompt and timely filing of a claim for the
unpaid balance of the indebtedness of such Guarantor owing to such Holder in the
form required in such proceedings and the causing of such claim to be approved.
If the Trustee does not file such a claim prior to 30 days before the expiration
of the time to file such a claim, the holders of Guarantor Senior Indebtedness,
or any Guarantor Representative, may, and hereby are authorized to, file such a
claim on behalf of Holders of the applicable Notes.

Section 11.14.    NOTICE TO TRUSTEE.

                  (a)   The Company or any Guarantor shall give prompt written
notice to a Responsible Officer of the Trustee of any fact known to the Company
or any such Guarantor which would prohibit the making of any payment to or by
the Trustee at its Corporate Trust Office in respect of the Guarantees pursuant
to the provisions of this Article 11. Notwithstanding the provisions of this
Article 11 or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Guarantees, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Guarantor Senior Indebtedness or from any trustee,
fiduciary, representative, or agent therefor no later than two Business Days
prior to such payment; and, prior to the receipt of any such written notice, the
Trustee, subject to the provisions of this Section 11.14, and subject to the
provisions of Sections 7.01 and 7.02, shall be entitled in all respects to
assume that no such facts exist; PROVIDED, HOWEVER, that if the Trustee shall
not have received the notice referred to in this Section 11.14 at least one
Business Day prior to the date upon which by the terms hereof any such payment
may become payable for any purpose under this Indenture (including, without
limitation, the payment of the principal of, premium, if any, or interest on any
Note), then, anything herein contained to the contrary notwithstanding but
without limiting the rights and remedies of the holders of Guarantor Senior
Indebtedness or any trustee, fiduciary, representative, or agent therefor as
against the Holders or any other Person, the Trustee shall have full power and
authority to receive such money and to apply the same to the purpose for which
such money was received and shall not be affected by any notice to the contrary
which may be received by it less than one Business Day prior to such date; nor
shall the Trustee be charged with knowledge of the curing of any such applicable
default in respect of Designated Senior Indebtedness or the elimination of the
act or condition preventing any such payment unless and until the Trustee shall
have received an Officers' Certificate to such effect (subject to the rights of
the holders of the Designated Senior Indebtedness under Section 11.09). Nothing
contained in this Section 11.14 shall limit the right of holders of Senior
Indebtedness to recover payments as contemplated by Section 11.08. The Trustee
shall be entitled to rely upon the delivery to it of a written notice by a
Person representing himself or itself to be a holder of any Senior Indebtedness
(or a trustee on behalf of, or other representative of, such holder) to
establish that such notice has been given by a holder of such Senior
Indebtedness or a trustee or representative on behalf of any such holder.

                  (b) Subject to the provisions of Section 7.01, the Trustee
shall be entitled to rely (to the extent reasonable and in good faith) on the
delivery to it of a written notice to the Trustee and the Company or a

<PAGE>
                                      -90-


Guarantor by a Person representing itself to be a holder of Guarantor Senior
Indebtedness (or a trustee, fiduciary, representative, or agent therefor) for
purposes of establishing that such notice actually has been given by a holder of
Guarantor Senior Indebtedness (or a trustee, fiduciary, representative, or agent
therefor); PROVIDED, HOWEVER, that failure to give such notice to the Company or
a Guarantor shall not affect in any way the ability of the Trustee to rely on
such notice. In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of
Guarantor Senior Indebtedness to participate in any payment or distribution
pursuant to this Article 11, the Trustee may request such Person to furnish
evidence not unsatisfactory to the Trustee as to the amount of Guarantor Senior
Indebtedness held by such Person, the extent to which such Person is entitled to
participate in such payment or distribution and any other facts pertinent to the
rights of such Person under this Article 11, and if such evidence is not
furnished, the Trustee, acting in good faith, may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment.

Section 11.15.    APPLICATION OF CERTAIN ARTICLE 11 PROVISIONS.

                              (REVERSE OF SECURITY)

               12 3/4% SENIOR SUBORDINATED NOTE DUE 2007, SERIES A

               1. INTEREST. AAVID THERMAL TECHNOLOGIES, INC., a Delaware
corporation (the "COMPANY"), promises to pay interest on the principal amount of
this Note at the rate PER ANNUM shown above. Interest on the Notes will accrue
from the most recent date on which interest has been paid or, if no interest has
been paid, from the date of the original issuance of the Notes. The Company will
pay interest semi-annually in arrears on each Interest Payment Date, commencing
August 1, 2000. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

                  The Company shall pay interest on overdue principal and on
overdue installments of interest (without regard to any applicable grace
periods) to the extent lawful from time to time on demand at the rate borne by
the Notes.

                  2. METHOD OF PAYMENT. The Company shall pay interest on the
Notes (except defaulted interest) to the Persons who are the registered Holders
at the close of business on July 15 or January 15 immediately preceding the
Interest Payment Date (whether or not such day is a Business Day) even if the
Notes are cancelled on registration of transfer or registration of exchange
after such Record Date. Holders must surrender Notes to a Paying Agent to
collect principal payments. Payments of principal and premium, if any, will be
made (on presentation of such Notes if in certificated form) in money of the
United States that at the time of payment is legal tender for payment of public
and private debts; PROVIDED, HOWEVER, that the Company may pay principal,
premium, if any, and interest by check payable or wire transfer in such money.
The Company may deliver any such interest payment to the Paying Agent or to a
Holder at the Holder's registered address.

                  3. PAYING AGENT AND REGISTRAR. Initially, Bankers Trust
Company, a New York banking corporation organized under the laws of the state of
New York (the "TRUSTEE"), will act as Paying Agent and Registrar. The Company
may change any Paying Agent, Registrar or co-Registrar without notice to the
Holders. Neither the Company nor any of its Subsidiaries or Affiliates may act
as Paying Agent but may act as Registrar or co-Registrar.

                  4.  INDENTURE.  The Company issued this Note under an
Indenture, dated as of, 2000 (the "INDENTURE"), by and among the Company, the
Guarantors and the Trustee.  This Note is one of a duly authorized issue of
Initial Notes of the Company designated as its 12 3/4% Senior Subordinated Notes
due 2007, Series A (the "NOTES"). The Notes are limited in aggregate principal
amount to $150,000,000. The Notes include the Initial Notes and the Exchange
Notes (as defined below) issued in exchange for the Initial Notes pursuant to
the Indenture. The Initial Notes and the Exchange Notes are treated as a single
class of securities under the Indenture. Capitalized terms herein are used as
defined in the Indenture unless otherwise defined herein. The terms of the Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (15 U.S. Code Sections 77aaa-
77bbbb)(the "TIA"), as in effect on the date of the Indenture. Notwithstanding
anything to the contrary herein, the Notes are subject to all such terms, and
Holders of Notes are referred to the Indenture and the TIA for a statement of
them.

                  5. SUBORDINATION. Except to the extent set forth in paragraph
10, the Notes are general unsecured obligations of the Company and subordinated
in right of payment, in the manner and to the extent set forth in the Indenture,
to the prior payment in full in cash of all Senior Indebtedness of the Company,
whether outstanding on the date of the Indenture or thereafter created,
incurred, assumed or guaranteed. Each Holder by his acceptance hereof agrees to
be bound by such provisions and authorizes and expressly directs the Trustee, on
his behalf, to take such action as may be necessary or appropriate to effectuate
the subordination provided for in the Indenture and appoints the Trustee his
attorney-in-fact for such purposes.

                  6. GUARANTEE. The obligations of the Company hereunder are
guaranteed on a senior subordinated basis by the Guarantors. Each Guarantee by a
Guarantor is subordinated in right of payment to all Guarantor Senior
Indebtedness of such Guarantor to the same extent that the Notes are
subordinated to Senior Indebtedness of the Company.

                  7.       REDEMPTION.

                  (a) The Notes will be redeemable at the option of the Company,
in whole or in part, during the 24-month period beginning February 1, 2004 at a
price equal to 100% of the principal amount thereof, plus an applicable Make
Whole Premium, and thereafter at 102% of the principal amount, in each case,
with accrued and unpaid interest, if any, to the date of redemption; PROVIDED,
HOWEVER, that at maturity the Notes shall be redeemable at 100% of principal
amount outstanding.

                  For the purposes of the foregoing, the "Make Whole Premium"
means, with respect to a Note, an amount equal to the excess, if any, of (1) the
present value as of the date of such prepayment of the remaining semi-annual
interest payments, if any, and the principal payment including premium due on
such Note as if such Note were redeemed on February 1, 2006, computed using a
discount rate equal to the Treasury Rate plus 75 basis points, over (2) the
outstanding principal amount of such Note. In no case shall the Make Whole
Premium be negative.

                  (b) OPTIONAL REDEMPTION UPON PUBLIC EQUITY OFFERINGS.
Notwithstanding the foregoing, the Company may redeem in the aggregate up to 35%
of the original principal amount of Notes at any time and from time to time
prior to February 2, 2003 at a Redemption Price equal to 112.75% of the
aggregate principal amount so redeemed, plus accrued and unpaid interest, if
any, to the Redemption Date out of the Net Proceeds of one or more Public Equity
Offerings; provided that

                  (1)  at least 65% of the principal amount of Notes originally
issued remains outstanding immediately after the occurrence of any such
redemption and

                  (2)  any such redemption occurs within 60 days following the
closing of any such Public Equity Offering.

                  8. NOTICE OF REDEMPTION. Notice of redemption under paragraphs
6(a) and 6(b) of this Note will be mailed at least 30 days but not more than 60
days before the Redemption Date to each Holder of Notes to be redeemed at such
Holder's registered address.

                  Except as set forth in the Indenture, if monies for the
redemption of the Notes called for redemption shall have been deposited with the
Paying Agent for redemption on such Redemption Date, then, unless the Company
defaults in the payment of such Redemption Price plus accrued interest, if any,
the Notes called for redemption will cease to bear interest from and after such
Redemption Date and the only right of the Holders of such Notes will be to
receive payment of the Redemption Price plus accrued interest, if any.

                  9. OFFERS TO PURCHASE. The Indenture provides that, after
certain Asset Sales and upon the occurrence of a Change of Control (as defined
in the Indenture), and subject to further limitations contained therein, the
Company will make an offer to purchase certain amounts of the Notes in
accordance with the procedures set forth in the Indenture.

                  10. REGISTRATION RIGHTS. Pursuant to the Registration Rights
Agreement by and among the Company, the Guarantors and the Initial Purchasers,
the Company will be obligated to consummate an exchange offer pursuant to which
the Holder of this Note shall have the right to exchange this Note for the
Company's % Senior Subordinated Notes due 2007, Series B (the "EXCHANGE NOTES"),

material respects other than this paragraph 10 to the Initial Notes. The Holders
of the Initial Notes shall be entitled to receive certain Additional Interest
payments in the event such exchange offer is not consummated and upon certain
other conditions, all pursuant to and in accordance with the terms of the
Registration Rights Agreement.

                  11. DENOMINATIONS; TRANSFER; EXCHANGE. The Notes are in
registered form, without coupons, in denominations of $1,000 and integral
multiples thereof. A Holder shall register the transfer or exchange of Notes in
accordance with the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
certain transfer taxes or similar governmental charges payable in connection
therewith as permitted by the Indenture. The Registrar need not register the
transfer of or exchange of any Notes or portions thereof selected for
redemption.

                  12. PERSONS DEEMED OWNERS. The registered Holder of a Note
shall be treated as the owner of it for all purposes.

                  13. UNCLAIMED MONEY. If money for the payment of principal or
interest remains unclaimed for two years, the Trustee and the Paying Agent will
pay the money back to the Company. After that, Holders entitled to money must
look to the Company for payment as general creditors unless an "abandoned
property" law designates another person.

                  14. DEFEASANCE AND COVENANT DEFEASANCE. If the Company at any
time deposits with the Trustee U.S. legal tender and/or U.S. Government
Obligations sufficient to pay the principal of and interest on the Notes to
redemption or maturity and complies with the other provisions of the Indenture
relating to defeasance, the Company will be discharged from certain provisions
of the Indenture and the Notes (including certain covenants, but excluding its
obligation to pay the principal of and interest on the Notes).

                  15. AMENDMENTS, SUPPLEMENTS, AND WAIVERS. Subject to certain
exceptions, the Indenture or the Notes may be amended or supplemented with the
written consent of the holders of at least a majority in aggregate principal
amount of the Notes then outstanding, and any existing Default or Event of
Default or noncompliance with any provision may be waived with the written
consent of the holders of a majority in aggregate principal amount of the Notes
then outstanding. Without notice to or consent of any Holder, the parties
thereto may amend or supplement the Indenture or the Notes to, among other
things, cure any ambiguity, defect or inconsistency, provide for uncertificated
Notes in addition to or in place of certificated Notes or make any other change
that does not adversely affect in any material respect the rights of any Holder
of a Note.

                  16. RESTRICTIVE COVENANTS. The Indenture imposes certain
limitations on the ability of the Company and its Restricted Subsidiaries to,
among other things, incur additional Indebtedness, make payments in respect of
its Capital Stock, enter into transactions with Affiliates, create dividend or
other payment restrictions affecting Subsidiaries, merge or consolidate with any
other person, or sell, assign, transfer, lease, convey or otherwise dispose of
all or substantially all of the Company's or any Guarantor's assets. Such
limitations are subject to a number of important qualifications and exceptions.
The Company must annually report to the Trustee on compliance with such
limitations.

                  17. SUCCESSOR ENTITY. When a successor entity assumes, in
accordance with the Indenture, all the obligations of its predecessor under the
Notes and the Indenture, and immediately before and thereafter no Default exists
and certain other conditions are satisfied, the predecessor entity will be
released from those obligations.

                  18. DEFAULTS AND REMEDIES. Events of Default are set forth in
the Indenture. If an Event of Default (other than an Event of Default pursuant
to Section 6.01(f) or (g) of the Indenture) shall have occurred and be
continuing, then the Trustee or the holders of not less than 25% in aggregate

<PAGE>
                                     -102-


Notes then outstanding, may declare to be immediately due and payable the entire
principal amount of all the Notes then outstanding plus accrued interest to the
date of acceleration; PROVIDED, HOWEVER, that after such acceleration but before
a judgment or decree based on such acceleration is obtained by the Trustee, the
holders of a majority in aggregate principal amount of the outstanding Notes may
rescind and annul such acceleration and its consequences if all existing Events
of Default, other than the nonpayment of principal, premium, if any, or interest
that has become due solely because of the acceleration, have been cured or
waived. No such rescission shall affect any subsequent Default or impair any
right consequent thereto. In case an Event of Default specified in Section
6.01(f) or (g) of the Indenture occurs, such principal amount, together with
premium, if any, and interest with respect to all of the Notes, shall be due and
payable immediately without any declaration or other act on the part of the
Trustee or the Holders.

deposits from, and perform services for the Company, and may otherwise deal with
the Company, its Subsidiaries or their respective Affiliates as if it were not
the Trustee.

                  20. NO RECOURSE AGAINST OTHERS. As more fully described in the
Indenture, no director, officer, employee, stockholder or incorporator, as such,
of the Company shall have any liability for any obligation of the Company under
the Notes or the Indenture or for any claim based on, in respect of or by reason
of such obligations or their creation. Each Noteholder by accepting a Note
waives and releases all such liability. Such waiver and release are part of the
consideration for the issuance of the Notes.

                  21. AUTHENTICATION. This Note shall not be valid until the
Trustee or Authenticating Agent manually signs the certificate of authentication
on this Note.

                  1. INTEREST. AAVID THERMAL TECHNOLOGIES, INC., a Delaware
corporation (the "COMPANY"), promises to pay interest on the principal amount of
this Note at the rate PER ANNUM shown above. Interest on the Notes will accrue
from the most recent date on which interest has been paid or, if no interest has
been paid, from the date of the original issuance of the Notes. The Company will
pay interest semi-annually in arrears on each Interest Payment Date, commencing
August 1, 2000. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

                  The Company shall pay interest on overdue principal and on
overdue installments of interest (without regard to any applicable grace
periods) to the extent lawful from time to time on demand at the rate borne by
the Notes.

                  2. METHOD OF PAYMENT. The Company shall pay interest on the
Notes (except defaulted interest) to the Persons who are the registered Holders
at the close of business on July 15 or January 15 preceding the Interest Payment
Date (whether or not such day is a Business Day) even if the Notes are cancelled
on registration of transfer or registration of exchange after such Record Date.
Holders must surrender Notes to a Paying Agent to collect principal payments.
Payments of principal and premium, if any, will be made (on presentation of such
Notes if in certificated form) in money of the United States that at the time of
payment is legal tender for payment of public and private debts; PROVIDED,
HOWEVER, that the Company may pay principal, premium, if any, and interest by
check payable in such money. The Company may deliver any such interest payment
to the Paying Agent or to a Holder at the Holder's registered address.

                  3. PAYING AGENT AND REGISTRAR. Initially, Bankers Trust
Company, a banking organization organized under the laws of New York (the
"TRUSTEE"), will act as Paying Agent and Registrar. The Company may change any
Paying Agent, Registrar or co-Registrar without notice to the Holders. Neither
the Company nor any of its Subsidiaries or Affiliates may act as Paying Agent
but may act as Registrar or co-Registrar.

                  4. INDENTURE. The Company issued this Note under an Indenture,
dated as of February 2, 2000 (the "INDENTURE"), by and among the Company, the
Guarantors and the Trustee. This Note is one of a duly authorized issue of Notes
of the Company designated as its 12 3/4% Senior Subordinated Notes due 2007,
Series B (the "EXCHANGE NOTES"), issued in exchange for the initial 12 3/4%
Senior Subordinated Notes due 2007, Series A (the "INITIAL NOTES" and, together
with the Exchange Notes, the "NOTES"). The Notes are limited in aggregate
principal amount to $150,000,000. Capitalized terms herein are used as defined
in the Indenture unless otherwise defined herein. The terms of the Notes include
those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the
"TIA"), as in effect on the date of the Indenture. Notwithstanding anything to
the contrary herein, the Notes are subject to all such terms, and Holders of
Notes are referred to the Indenture and the TIA for a statement of them.

                  5. SUBORDINATION. Except to the extent set forth in paragraph
10, the Notes are general unsecured obligations of the Company and subordinated
in right of payment, in the manner and to the extent set forth in the Indenture,
to the prior payment in full in cash of all Senior Indebtedness of the Company,
whether outstanding on the date of the Indenture or thereafter created,
incurred, assumed or guaranteed. Each Holder by his acceptance hereof agrees to
be bound by such provisions and authorizes and expressly directs the Trustee, on
his behalf, to take such action as may be necessary or appropriate to effectuate
the subordination provided for in the Indenture and appoints the Trustee his
attorney-in-fact for such purposes.

                                     -109-


                  6. GUARANTEE. The obligations of the Company hereunder are
guaranteed on a senior subordinated basis by the Guarantors. Each Guarantee by a
Guarantor is subordinated in right of payment to all Guarantor Senior
Indebtedness of such Guarantor to the same extent that the Notes are
subordinated to Senior Indebtedness of the Company.

                  7.       REDEMPTION.

                  (a) The Notes will be redeemable at the option of the Company,
in whole or in part, during the 24-month period beginning February 1, 2004 at a
price equal to 100% of the principal amount thereof, plus and applicable Make
Whole Premium, and thereafter at 102% of the principal amount, in each case,
with accrued and unpaid interest, if any, to the date of redemption; PROVIDED,
HOWEVER, that at maturity the Notes shall be redeemable at 100% of principal
amount outstanding.

                  For the purposes of the foregoing, the "Make Whole Premium"
means, with respect to a Note, an amount equal to the excess, if any, of (1) the
present value as of the date of such prepayment of the remaining semi-annual
interest payments, if any, and the principal payment including premium due on
such Note as if such Note were redeemed on February 1, 2006, computed using a
discount rate equal to the Treasury Rate plus 75 basis points, over (2) the
outstanding principal amount of such Note. In no case shall the Make Whole
Premium be negative.

                  (b) OPTIONAL REDEMPTION UPON PUBLIC EQUITY OFFERINGS.
Notwithstanding the foregoing, the Company may redeem in the aggregate up to 35%
of the original principal amount of Notes at any time and from time to time
prior to February 2, 2003 at a Redemption Price equal to 112.75% of the
aggregate principal amount so redeemed, plus accrued and unpaid interest, if
any, to the Redemption Date out of the Net Proceeds of one or more Public Equity
Offerings; provided that

                  (1) at least 65% of the principal amount of Notes originally
         issued remains outstanding immediately after the occurrence of any such
         redemption and

                  (2) any such redemption occurs within 60 days following the
         closing of any such Public Equity Offering.

                  8. NOTICE OF REDEMPTION. Notice of redemption under paragraphs
6(a) and 6(b) of this Note will be mailed at least 30 days but not more than 60
days before the Redemption Date to each Holder of Notes to be redeemed at such
Holder's registered address.

                  Except as set forth in the Indenture, if monies for the
redemption of the Notes called for redemption shall have been deposited with the
Paying Agent for redemption on such Redemption Date, then, unless the Company
defaults in the payment of such Redemption Price plus accrued interest, if any,
the Notes called for redemption will cease to bear interest from and after such
Redemption Date and the only right of the Holders of such Notes will be to
receive payment of the Redemption Price plus accrued interest, if any.

                  9. OFFERS TO PURCHASE. The Indenture provides that, after
certain Asset Sales and upon the occurrence of a Change of Control (as defined
in the Indenture), and subject to further limitations contained therein, the
Company will make an offer to purchase certain amounts of the Notes in
accordance with the procedures set forth in the Indenture.

                  10. DENOMINATIONS; TRANSFER; EXCHANGE. The Notes are in
registered form, without coupons, in denominations of $1,000 and integral
multiples thereof. A Holder shall register the transfer or exchange of Notes in
accordance with the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
certain transfer taxes or similar governmental

<PAGE>
                                     -110-


charges payable in connection therewith as permitted by the Indenture. The
Registrar need not register the transfer of or exchange of any Notes or portions
thereof selected for redemption.

                  11. PERSONS DEEMED OWNERS. The registered Holder of a Note
shall be treated as the owner of it for all purposes.

                  12. UNCLAIMED MONEY. If money for the payment of principal or
interest remains unclaimed for two years, the Trustee and the Paying Agent will
pay the money back to the Company. After that, Holders entitled to money must
look to the Company for payment as general creditors unless an "abandoned
property" law designates another person.

                  13. DEFEASANCE AND COVENANT DEFEASANCE. If the Company at any
time deposits with the Trustee U.S. legal tender and/or U.S. Government
Obligations sufficient to pay the principal of and interest on the Notes to
redemption or maturity and complies with the other provisions of the Indenture
relating to defeasance, the Company will be discharged from certain provisions
of the Indenture and the Notes (including certain covenants, but excluding its
obligation to pay the principal of and interest on the Notes).

                  14. AMENDMENTS, SUPPLEMENTS, AND WAIVERS. Subject to certain
exceptions, the Indenture or the Notes may be amended or supplemented with the
written consent of the holders of at least a majority in aggregate principal
amount of the Notes then outstanding, and any existing Default or Event of
Default or noncompliance with any provision may be waived with the written
consent of the holders of a majority in aggregate principal amount of the Notes
then outstanding. Without notice to or consent of any Holder, the parties
thereto may amend or supplement the Indenture or the Notes to, among other
things, cure any ambiguity, defect or inconsistency, provide for uncertificated
Notes in addition to or in place of certificated Notes or make any other change
that does not adversely affect in any material respect the rights of any Holder
of a Note.

                  15. RESTRICTIVE COVENANTS. The Indenture imposes certain
limitations on the ability of the Company and its Restricted Subsidiaries to,
among other things, incur additional Indebtedness, make payments in respect of
its Capital Stock, enter into transactions with Affiliates, create dividend or
other payment restrictions affecting Subsidiaries, merge or consolidate with any
other person, or sell, assign, transfer, lease, convey or otherwise dispose of
all or substantially all of the Company's or any Guarantor's assets. Such
limitations are subject to a number of important qualifications and exceptions.
The Company must annually report to the Trustee on compliance with such
limitations.

                  16. SUCCESSOR ENTITY. When a successor entity assumes, in
accordance with the Indenture, all the obligations of its predecessor under the
Notes and the Indenture, and immediately before and thereafter no Default exists
and certain other conditions are satisfied, the predecessor entity will be
released from those obligations.

                  17. DEFAULTS AND REMEDIES. Events of Default are set forth in
the Indenture. If an Event of Default (other than an Event of Default pursuant
to Section 6.01(f) or (g) of the Indenture) shall have occurred and be
continuing, then the Trustee or the holders of not less than 25% in aggregate
principal amount of the Notes then outstanding, may declare to be immediately
due and payable the entire principal amount of all the Notes then outstanding
plus accrued interest to the date of acceleration; PROVIDED, HOWEVER, that after
such acceleration but before a judgment or decree based on such acceleration is
obtained by the Trustee, the holders of a majority in aggregate principal amount
of the outstanding Notes may rescind and annul such acceleration and its
consequences if all existing Events of Default, other than the nonpayment of
principal, premium, if any, or interest that has become due solely because of
the acceleration, have been cured or waived. No such rescission shall affect any
subsequent Default or impair any right consequent thereto. In case an Event of
Default specified in Section 6.01(f) or (g) of the Indenture occurs, such
principal amount, together with premium, if any, and interest

<PAGE>
                                     -111-


with respect to all of the Notes, shall be due and payable immediately without
any declaration or other act on the part of the Trustee or the Holders.

                  18. TRUSTEE DEALINGS WITH COMPANY. The Trustee under the
Indenture, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company, and may otherwise deal with
the Company, its Subsidiaries or their respective Affiliates as if it were not
the Trustee.

                  19. NO RECOURSE AGAINST OTHERS. As more fully described in the
Indenture, no director, officer, employee, stockholder or incorporator, as such,
of the Company shall have any liability for any obligation of the Company under
the Notes or the Indenture or for any claim based on, in respect of or by reason
of such obligations or their creation. Each Noteholder by accepting a Note
waives and releases all such liability. Such waiver and release are part of the
consideration for the issuance of the Notes.

                  20. AUTHENTICATION. This Note shall not be valid until the
Trustee or Authenticating Agent manually signs the certificate of authentication
on this Note.

                  21. GOVERNING LAW. THIS NOTE SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO
CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAW. EACH OF THE PARTIES TO THE INDENTURE HAS AGREED
TO SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY
ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE.

                  22. ABBREVIATIONS AND DEFINED TERMS. Customary abbreviations

                  22. CUSIP NUMBERS. Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures, the Company has

bound by all of the terms and provisions of the Indenture, as the same may be
amended from time to time.

Bankers Trust Company
Four Albany Street
New York, New York  10006
Attention:  Corporate Trust and Agency Services

Ladies and Gentlemen:

                  This certificate is delivered to request a transfer of
$________ principal amount of the 12 3/4% Senior Subordinated Notes due 2007,
Series A, of Aavid Thermal Technologies, Inc. (the "COMPANY") and any guarantee
thereof (the "NOTES"). Upon transfer, the Notes would be registered in the name
of the new beneficial owner as follows:

                  Name:---------------------------------------------
                  Address:------------------------------------------
                  Taxpayer ID Number:-------------------------------

                  The undersigned represents and warrants to you that:

                  1. We are an institutional "accredited investor" (as defined
in Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933 (the
"SECURITIES ACT")) purchasing Notes for our own account or for the account of
such an institutional "accredited investor" and we are acquiring the Notes not
with a view to, or for offer or sale in connection with, any distribution in
violation of the Securities Act. We have such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risk of our investment in the Notes and we invest in or purchase securities
similar to the Notes in the normal course of our business. We and any accounts
for which we are acting are each able to bear the economic risk of our or its
investment.

                  2. We acknowledge that we have had access to such financial
and other information, and have been afforded the opportunity to ask such
questions of representatives of the Company and receive answers thereto, as we
deem necessary.

                  3. We understand that the Notes have not been registered under
the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence. We agree on our own behalf and on behalf of
any investor account for which we are purchasing Notes that we will not prior to
the date (the "RESALE RESTRICTION TERMINATION DATE") that is two years after the
later of the original issuance of the Note and the last date on which the
Company or any affiliate of the Company was the owner of such Notes (or any
predecessor thereto) offer, sell or otherwise transfer such Notes except (a) to
the Company or any subsidiary of the Company, (b) inside the United States to a
"qualified institutional buyer" in compliance with Rule 144A under the
Securities Act (c) inside the United States to an "institutional accredited
investor" as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act
that, prior to such transfer, furnishes (or has furnished on its behalf by a
U.S. broker-dealer) to the Trustee a signed letter substantially in the form of
this letter (d) outside the United States in an offshore transaction in
compliance with Rule 904 under the Securities Act (e) pursuant to any other
available exemption from the registration requirements of the Securities Act or
(f) pursuant to an effective registration statement under the Securities Act. We
acknowledge that the Company and the Trustee reserve the right prior to any
offer, sale or other transfer prior to the Resale Restriction Termination Date
of the applicable Notes pursuant to clause (c) or (e) above to require the
delivery of an opinion of counsel, certification and/or other information
satisfactory to the Company and the Trustee.

                                      -2-


                                    ARTICLE I

                     ISSUANCE, FORM, EXECUTION, DELIVERY AND
                      REGISTRATION OF WARRANT CERTIFICATES

                  SECTION 1.01. Issuance of Warrants. Warrants comprising part
of the Units shall be originally issued in connection with the issuance of the
Units and such Warrants shall not be separately transferable from the Notes
until on or after the Separability Date as provided in Section 1.06 hereof.

                  Each Warrant Certificate shall evidence the number of Warrants
specified therein, and each Warrant evidenced thereby shall, when exercisable as
provided herein and therein, represent the right, subject to the provisions
contained herein and therein, to purchase from the Company (and the Company
shall issue and sell to the holder of such Warrant upon exercise thereof) 0.0004
fully paid and non-assessable shares of the Company's Class A Common Stock at an
exercise price of $0.01 per share and 0.0004 fully paid and non-assessable
shares of the Company's Class H Common Stock at an exercise price of $0.01 per
share. The shares purchasable upon exercise of a Warrant are hereinafter
referred to as the "Shares" and are subject to adjustment as provided herein and
in the Warrant, and, unless the context otherwise requires, such term shall also
include any other securities or property purchasable and deliverable upon
exercise of a Warrant as provided in Article V, subject to adjustment as
provided herein and in the Warrant.

                  SECTION 1.02. Form of Warrant Certificates. The Warrant
Certificates will initially be issued either in global form as 144A Global
Warrants or Regulation S Global Warrants (collectively, the "Global Warrants"),
substantially in the form of Exhibit A hereto, or in registered form as
definitive Warrant Certificates (the "Definitive Warrants") substantially in the
form of Exhibit A attached hereto. Any Global Warrants to be delivered pursuant
to this Agreement shall bear the legend set forth in Exhibit B attached hereto.
Such Global Warrants shall represent such of the outstanding Warrants as shall
be specified therein and each shall provide that it shall represent the
aggregate amount of outstanding Warrants from time to time endorsed thereon and
that the aggregate amount of outstanding Warrants represented thereby may from
time to time be reduced or increased, as appropriate. Any endorsement of a
Global Warrant to reflect the amount of any increase or decrease in the amount
of outstanding Warrants represented thereby shall be made by the Warrant Agent
and the Depository (as defined below) in accordance with instructions given by
the holder thereof. The Depository Trust Company shall act as the Depository
with respect to the Global Warrants until a successor shall be appointed by the
Company and the Warrant Agent. Upon written request, a holder of record of
Warrants may receive from the Warrant Agent or the Depository Definitive
Warrants as set forth in Section 1.08 hereof.

                  "144A Global Warrant" means a permanent global security in
registered form representing the aggregate principal amount of Warrants sold in
reliance on Rule 144A.

                  "Regulation S Global Warrant" means a permanent global
security in registered form representing the aggregate principal amount of
Warrants sold in reliance on Regulation S under the Securities Act.

                  SECTION 1.03. Execution of Warrant Certificates. The Warrant
Certificates shall be executed on behalf of the Company by the chairman of its
Board of Directors, its president or any vice president and attested by its
secretary or assistant secretary. Such signatures may be the manual or facsimile
signatures of the present or any future such officers. Typographical and other
minor errors or defects in any such reproduction of any such signature shall not
affect the validity or enforceability of any Warrant Certificate that has been
duly countersigned and delivered by the Warrant Agent.

                  In case any officer of the Company who shall have signed any
of the Warrant Certificates shall cease to be such officer before the Warrant
Certificate so signed shall be countersigned and delivered by the Warrant Agent
or disposed of by the Company, such Warrant Certificate nevertheless may be
countersigned and delivered or disposed of as though the person who signed such
Warrant Certificate had not ceased to be such officer of the Company; and any
Warrant Certificate may be signed on behalf of the Company by such persons as,
at the actual date of the execution of such Warrant Certificate, shall be the
proper officers of the Company, although at the date of the execution and
delivery of this Agreement any such person was not such an officer.

                  SECTION 1.04. Authentication and Delivery. Subject to the
immediately following paragraph, Warrant Certificates shall be authenticated by
manual signature and dated the date of authentication by the Warrant Agent and
shall not be valid for any purpose unless so authenticated and dated. The
Warrant Certificates shall be numbered and shall be registered in the Warrant
Register (as defined in Section 1.07 hereof).

                  Upon the receipt by the Warrant Agent of a written order of
the Company, which order shall be signed by the chairman of its Board of
Directors, its president or any vice president and attested by its secretary or
assistant secretary, and shall specify the amount of Warrants to be
authenticated, whether the Warrants are to be Global Warrants or Definitive
Warrants, the date of such Warrants and such other information as the Warrant
Agent may reasonably request, without any further action by the Company, the
Warrant Agent is authorized, upon receipt from the Company at any time and from
time to time of the Warrant Certificates, duly executed as provided in Section
1.03 hereof, to authenticate the Warrant Certificates and upon the holder's
request deliver them. Such authentication shall be by a duly

<PAGE>

                                      -4-


authorized signatory of the Warrant Agent (although it shall not be necessary
for the same signatory to sign all Warrant Certificates).

                  In case any authorized signatory of the Warrant Agent who
shall have authenticated any of the Warrant Certificates shall cease to be such
authorized signatory before the Warrant Certificate shall be disposed of by the
Company or the Warrant Agent, such Warrant Certificate nevertheless may be
delivered or disposed of as though the person who authenticated such Warrant
Certificate had not ceased to be such authorized signatory of the Warrant Agent;
and any Warrant Certificate may be authenticated on behalf of the Warrant Agent
by such persons as, at the actual time of authentication of such Warrant
Certificates, shall be the duly authorized signatories of the Warrant Agent,
although at the time of the execution and delivery of this Agreement any such
person is not such an authorized signatory.

                  The Warrant Agent's authentication on all Warrant Certificates
shall be in substantially the form set forth in Exhibit A hereto.

                  SECTION 1.05. Temporary Warrant Certificates. Pending the
preparation of definitive Warrant Certificates, the Company may execute, and the
Warrant Agent shall authenticate and deliver, temporary Warrant Certificates,
which are printed, lithographed, typewritten or otherwise produced,
substantially of the tenor of the definitive Warrant Certificates in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Warrant
Certificates may determine, as evidenced by their execution of such Warrant
Certificates.

                  If temporary Warrant Certificates are issued, the Company will
cause definitive Warrant Certificates to be prepared without unreasonable delay.
After the preparation of definitive Warrant Certificates, the temporary Warrant
Certificates shall be exchangeable for definitive Warrant Certificates upon
surrender of the temporary Warrant Certificates at any office or agency
maintained by the Company for that purpose pursuant to Section 1.10 hereof.
Subject to the provisions of Section 4.01 hereof, such exchange shall be without
charge to the holder. Upon surrender for cancellation of any one or more
temporary Warrant Certificates, the Company shall execute, and the Warrant Agent
shall authenticate and deliver in exchange therefor, one or more definitive
Warrant Certificates representing in the aggregate a like number of Warrants.
Until so exchanged, the holder of a temporary Warrant Certificate shall in all
respects be entitled to the same benefits under this Agreement as a holder of a
definitive Warrant Certificate.

                  SECTION 1.06. Separation of Warrants and Notes. The Notes and
the Warrants will not be separately transferable until the Separability Date.
"Separability Date" shall mean the earliest to occur of: (1) 180 days after the
Issue Date (as defined in the Indenture); (2) the occurrence of a Change of
Control (as defined in the Indenture); (3) the



<PAGE>

                                      -5-


occurrence of an Event of Default (as defined in the Indenture); (4) the
effectiveness of a registration statement under the Securities Act of 1933, as
amended (the "Securities Act") with respect to the Notes or the Exchange Notes
(as defined in the Indenture); or (5) such earlier date as determined by CIBC in
its discretion and specified to the Company, the Trustee and the Warrant Agent
in writing. The surrender of a Unit certificate for separate Warrant
certificates and Note certificates is herein referred to as a "Separation." The
Company shall promptly notify the Warrant Agent of the Separability Date.
Following the Separability Date, no Unit certificates shall be issued.

                  SECTION 1.07. Registration. The Company will keep, at the
office or agency maintained by the Company for such purpose, a register or
registers in which, subject to such reasonable regulations as it may prescribe,
the Company shall provide for the registration of, and registration of transfer
and exchange of, Warrants as provided in this Article. Each person designated by
the Company from time to time as a person authorized to register the transfer
and exchange of the Warrants is hereinafter called, individually and
collectively, the "Registrar." The Company hereby initially appoints the Warrant
Agent as Registrar. Upon written notice to the Warrant Agent and any acting
Registrar, the Company may appoint a successor Registrar for such purposes.

                  The Company will at all times designate one person (who may be
the Company and who need not be a Registrar) to act as repository of a master
list of names and addresses of the holders of Warrants (the "Warrant Register").
The Warrant Agent will act as such repository unless and until some other person
is, by written notice from the Company to the Warrant Agent and the Registrar,
designated by the Company to act as such. The Company shall cause each Registrar
to furnish to such repository, on a current basis, such information as to all
registrations of transfer and exchanges effected by such Registrar, as may be
necessary to enable such repository to maintain the Warrant Register on as
current a basis as is practicable.

                  SECTION 1.08.     Registration of Transfers or Exchanges.

                  (a) Transfer or Exchange of Definitive Warrants. When
Definitive Warrants are presented to the Warrant Agent with a request from the
holder:

           (i)    to register the transfer of the Definitive Warrants; or

          (ii)    to exchange such Definitive Warrants for an equal number of
                  Definitive Warrants of other authorized denominations,

the Warrant Agent shall register the transfer or make the exchange as requested
if the requirements under this Warrant Agreement as set forth in this Section
1.08 hereof for such

<PAGE>
                                      -6-


transactions are met; provided, however, that the Definitive Warrants presented
or surrendered by a holder for registration of transfer or exchange:

         (x)      shall be duly endorsed or accompanied by a written instruction
                  of transfer or exchange in form satisfactory to the Company
                  and the Warrant Agent, duly executed by such holder or by his
                  attorney, duly authorized in writing; and

         (y)      in the case of Warrants the offer and sale of which have not
                  been registered under the Securities Act and are presented for
                  transfer or exchange prior to (X) the date which is two years
                  (or such shorter period as may be prescribed by Rule 144(k)
                  (or any successor provision thereto)) after the later of the
                  date of original issuance of the Warrants and the last date on
                  which the Company or any affiliate of the Company was the
                  owner of such Warrants, or any predecessor thereto, and (Y)
                  such later date, if any, as may be required by any subsequent
                  change in applicable law (the "Resale Restriction Termination
                  Date"), such Warrants shall be accompanied by the following
                  additional information and documents, as applicable:

                  (A)      If such Warrants are being delivered to the Warrant
                           Agent by a holder for registration in the name of
                           such holder, without transfer, a certification from
                           such holder to that effect (in substantially the
                           form of Exhibit C hereto); or

                  (B)      if such Warrants are being transferred to a qualified
                           institutional buyer (as defined in Rule 144A under
                           the Securities Act) (a "QIB") in accordance with Rule
                           144A under the Securities Act, a certification from
                           the transferor to that effect (in substantially the
                           form of Exhibit C hereto); or

                  (C)      if such Warrants are being transferred to an
                           institutional "accredited investor" within the
                           meaning of subparagraphs (a)(1), (a)(2), (a)(3) or
                           (a)(7) of Rule 501 under the Securities Act (an
                           "Institutional Accredited Investor"), delivery by the
                           transferor of a certification to that effect (in
                           substantially the form of Exhibit C hereto), and
                           delivery by the proposed transferee of a Transferee
                           Certificate for Institutional Accredited Investors
                           (in substantially the form of Exhibit D hereto); or

                  (D)      if such Warrants are being transferred in reliance on
                           Regulation S under the Securities Act, delivery by
                           the transferor of a certification to that effect (in
                           substantially the form of Exhibit C hereto), and a
                           Certificate for Regulation S Transfers in the form of
                           Exhibit E hereto; or

<PAGE>
                                      -7-



                  (E)      if such Warrants are being transferred in reliance on
                           Rule 144 under the Securities Act, delivery by the
                           transferor of (i) a certification from the transferor
                           to that effect (in substantially the form of Exhibit
                           C hereto), and (ii) an opinion of counsel reasonably
                           satisfactory to the Company to the effect that such
                           transfer is in compliance with the Securities Act; or

                  (F)      if such Warrants are being transferred in reliance on
                           another exemption from the registration requirements
                           of the Securities Act, a certification from the
                           transferor to that effect (in substantially the form
                           of Exhibit C hereto) and an opinion of counsel
                           reasonably satisfactory to the Company to the effect
                           that such transfer is in compliance with the
                           Securities Act; provided that the Company may, based
                           upon the views of its own counsel, instruct the
                           Warrant Agent not to register such transfer in any
                           case where the proposed transferee is not a QIB,
                           Non-U.S. Person or Institutional Accredited Investor.

                  (b) Restrictions on Transfer of a Definitive Warrant for a
Beneficial Interest in a Global Warrant. A Definitive Warrant may not be
transferred by a holder for a beneficial interest in a Global Warrant except
upon satisfaction of the requirements set forth below. Upon receipt by the
Warrant Agent of a Definitive Warrant, duly endorsed or accompanied by
appropriate instruments of transfer, in form satisfactory to the Warrant Agent,
together with:

                  (A)      certification from such holder (in substantially the
                           form of Exhibit C hereto) that such Definitive
                           Warrant is being transferred to (I) a QIB in
                           accordance with Rule 144A under the Securities Act,
                           (II) to an Institutional Accredited Investor or (III)
                           in an offshore transaction in reliance on Regulation
                           S and, with respect to (II) or (III), at the option
                           of the Company or the Warrant Agent, an Opinion of
                           Counsel reasonably acceptable to the Company to the
                           effect that such transfer is in compliance with the
                           Securities Act; and

                  (B)      written instructions directing the Warrant Agent to
                           make, or to direct the Depository to make, an
                           endorsement on the applicable Global Warrant to
                           reflect an increase in the aggregate amount of the
                           Warrants represented by the Global Warrant,

then the Warrant Agent shall cancel such Definitive Warrant and cause, or direct
the Depository to cause, in accordance with the standing instructions and
procedures existing between the Depository and the Warrant Agent, the number of
Shares represented by the applicable Global Warrant to be increased accordingly.
If no 144A Global Warrant or Regulation S

<PAGE>
                                      -8-



Global Warrant is then outstanding, the Company shall issue and the Warrant
Agent shall upon written instructions from the Company authenticate a new Global
Warrant in the appropriate amount.

                  (c) Transfer or Exchange of Global Warrants. The transfer or
exchange of Global Warrants or beneficial interests therein shall be effected
through the Depository, in accordance with this Section 1.08, the Private
Placement Legend, this Agreement (including the restrictions on transfer set
forth herein) and the procedures of the Depository therefor. Upon receipt by the
Registrar or Co-Registrar of written instructions, or such other instruction as
is customary for the Depository, from the Depository or its nominee, requesting
the registration of transfer of an interest in a 144A Global Warrant, a
Regulation S Global Warrant, as the case may be, to another type of Global
Warrant, together with the applicable Global Warrants (or, if the applicable
type of Global Warrant required to represent the interest as requested to be
obtained is not then outstanding, only the Global Warrant representing the
interest being transferred), the Registrar or Co-Registrar shall reflect on its
books and records (and the applicable Global Warrant) the applicable increase
and decrease of the principal amount of Warrants represented by such types of
Global Warrants, giving effect to such transfer. If the applicable type of
Global Warrant required to represent the interest as requested to be obtained is
not outstanding at the time of such request, the Company shall issue and the
Warrant Agent shall, upon written instructions from the Company in accordance
with Section 1.08, authenticate a new Global Warrant of such type in principal
amount equal to the principal amount of the interest requested to be
transferred.

                  (d)  Transfer or Exchange of a Beneficial Interest in a Global
Warrant for a Definitive Warrant.

              (i)    Any person having a beneficial interest in a Global Warrant
                     may transfer or exchange such beneficial interest for a
                     Definitive Warrant; provided, however, that prior to the
                     Registration, a transferee that is a QIB or Institutional
                     Accredited Investor may not exchange a beneficial interest
                     in a Global Warrant for a Definitive Warrant until receipt
                     by the Warrant Agent of written instructions or such other
                     form of instructions as is customary for the Depository
                     from the Depository or its nominee on behalf of any person
                     having a beneficial interest in a Global Warrant, including
                     a written order containing registration instructions and,
                     in the case of any such transfer or exchange of a
                     beneficial interest in Warrants the offer and sale of which
                     have not been registered under the Securities Act, the
                     following additional information and documents:

                  (A)      if such beneficial interest is being transferred to
                           the person designated by the Depository as being the
                           beneficial owner, a certification from such person

                           to that effect (in substantially the form of Exhibit
                           C hereto); or

                  (B)      if such beneficial interest is being transferred in
                           reliance on Regulation S under the Securities Act,
                           delivery by the transferor of (i) a certification to
                           that effect (in substantially the form of Exhibit C
                           hereto), and (ii) a Certificate for Regulation S
                           Transfers in the form of Exhibit E hereto; or

                  (C)      if such beneficial interest is being transferred in
                           reliance on Rule 144 under the Securities Act,
                           delivery by the transferor of (i) a certification to
                           that effect (in substantially the form of Exhibit C
                           hereto) and (ii) an opinion of counsel reasonably
                           satisfactory to the Company to the effect that such
                           transfer is in compliance with the Securities Act; or

                  (D)     if such beneficial interest is being transferred in
                          reliance on another exemption from the registration
                          requirements of the Securities Act, a certification
                          from the transferor to that effect (in substantially
                          the form of Exhibit C hereto) and an opinion of
                          counsel reasonably satisfactory to the Company to the
                          effect that such transfer is in compliance with the
                          Securities Act; provided that the Company may instruct
                          the Warrant Agent not to register such transfer in any
                          case where the proposed transferee is not a QIB,
                          Non-U.S. Person or Institutional Accredited Investor.

                  then the Warrant Agent will cause, in accordance with the
                  standing instructions and procedures existing between the
                  Depository and the Warrant Agent, the aggregate amount of the
                  Global Warrant to be reduced and, following such reduction,
                  the Company will execute and, upon receipt of an
                  authentication order in the form of an officers' certificate
                  (a certificate signed by two officers of the Company, one of
                  whom must be the principal executive officer, principal
                  financial officer or principal accounting officer) (an
                  "Officers' Certificate"), the Warrant Agent will authenticate
                  and deliver to the transferee a Definitive Warrant. The
                  Warrant Agent shall not be deemed to have knowledge of any
                  registration under the Securities Act unless it receives an
                  Officers' Certificate specifying such registration.

          (ii)    Definitive Warrants issued in exchange for a beneficial
                  interest in a Global Warrant pursuant to this Section 1.08(d)
                  shall be registered in such names and in such authorized
                  denominations as the Depository, shall instruct the Warrant
                  Agent in writing. The Warrant Agent shall deliver such
                  Definitive Warrants

<PAGE>
                                      -10-


                  to the persons in whose names such Warrants are so registered
                  and adjust the Global Warrant pursuant to paragraph (h) of
                  this Section 1.08.

                  (e) Restrictions on Transfer or Exchange of Global Warrants.
Notwithstanding any other provisions of this Agreement (other than the
provisions set forth in subsection (f) of this Section 1.08), a Global Warrant
may not be transferred or exchanged as a whole except by the Depository to a
nominee of the Depository or by a nominee of the Depository to the Depository or
another nominee of the Depository or by the Depository or any such nominee to a
successor Depository or a nominee of such successor Depository.

                  (f) Authentication of Definitive Warrants in Absence of
Depository. If at any time:

           (i)    the Depository for the Global Warrants notifies the Company
                  and the Warrant Agent that the Depository is unwilling or
                  unable to continue as Depository for the Global Warrants and a
                  successor Depository for the Global Warrants is not appointed
                  by the Company within 90 days after delivery of such notice;
                  or

          (ii)    The Company, at its sole discretion, notifies the Warrant
                  Agent in writing that it elects to cause the issuance of
                  Definitive Warrants for all Global Warrants under this
                  Agreement,

then the Company will execute, and the Warrant Agent will, upon receipt of an
Officers' Certificate requesting the authentication and delivery of Definitive
Warrants, authenticate and deliver Definitive Warrants, in an aggregate number
equal to the aggregate number of warrants represented by the Global Warrant, in
exchange for such Global Warrant.

                  (g) Private Placement Legend. Upon the registration of
transfer, exchange or replacement of Warrant Certificates not bearing the legend
set forth in the first paragraph of Exhibit A attached hereto (the "Private
Placement Legend"), the Warrant Agent shall deliver Warrant Certificates that do
not bear the Private Placement Legend. Upon the registration of transfer,
exchange or replacement of Warrant Certificates bearing the Private Placement
Legend, the Warrant Agent shall deliver Warrant Certificates that bear the
Private Placement Legend unless, and the Warrant Agent is hereby authorized to
deliver Warrant Certificates without the Private Placement Legend if, (i) the
requested transfer is not prior to the date which is two years (or such shorter
period as may be prescribed by Rule 144(k) (or any successor provision thereto)
under the Securities Act or any successor provision thereunder) after the later
of the original Issue Date of the Warrants or the last day on which the Company
or any of its Affiliates was the owner of the Warrant or any predecessor
security, (ii) there is delivered to the Warrant Agent an opinion of counsel
reasonably satisfactory to the Company and the Warrant Agent to the effect that
neither such legend nor the related restrictions on

<PAGE>
                                      -11-



transfer are required in order to maintain compliance with the provisions of the
Securities Act or (iii) the Warrants to be transferred or exchanged represented
by such Warrant Certificates are being transferred or exchanged pursuant to an
effective registration statement under the Securities Act.

                  (h) Cancellation or Adjustment of a Global Warrant. At such
time as all beneficial interests in a Global Warrant have either been exchanged
for Definitive Warrants, redeemed, repurchased or cancelled, such Global Warrant
shall be returned to the Company or, upon written order to the Warrant Agent in
the form of an Officers' Certificate from the Company, retained and cancelled by
the Warrant Agent. At any time prior to such cancellation, if any beneficial
interest in a Global Warrant is exchanged for Definitive Warrants, redeemed,
repurchased or cancelled, the number of Warrants represented by such Global
Warrant shall be reduced and an endorsement shall be made on such Global Warrant
by the Warrant Agent to reflect such reduction.

                  (i)  Obligations with Respect to Transfers or Exchanges of
                       Definitive Warrants.

           (i)    To permit registrations of transfers or exchanges, the Company
                  shall execute, at the Warrant Agent's request, and the Warrant
                  Agent shall authenticate Definitive Warrants and Global
                  Warrants.

          (ii)    All Definitive Warrants and Global Warrants issued upon any
                  registration, transfer or exchange of Definitive Warrants or
                  Global Warrants shall be the valid obligations of the Company,
                  entitled to the same benefits under this Warrant Agreement as
                  the Definitive Warrants or Global Warrants surrendered upon
                  the registration of transfer or exchange.

         (iii)    Prior to due presentment for registration of transfer of any
                  Warrant, the Warrant Agent and the Company may deem and treat
                  the person in whose name any Warrant is registered as the
                  absolute owner of such Warrant, and neither the Warrant Agent
                  nor the Company shall be affected by notice to the contrary.

                  "Depository" means, with respect to the Warrants issued in the
form of one or more Global Securities, The Depository Trust Company or another
Person designated as Depository by the Company, which must be a clearing agency
registered under the Exchange Act.

                  SECTION 1.09. Lost, Stolen, Destroyed, Defaced or Mutilated
Warrant Certificates. Upon receipt by the Company and the Warrant Agent (or any
agent of the Company or the Warrant Agent, if requested by the Company) of
evidence satisfactory to them of


<PAGE>
                                      -12-


the loss, theft, destruction, defacement, or mutilation of any Warrant
Certificate and of an indemnity bond satisfactory to them and, in the case of
mutilation or defacement, upon surrender thereof to the Warrant Agent for
cancellation, then, in the absence of notice to the Company or the Warrant Agent
that such Warrant Certificate has been acquired by a bona fide purchaser or
holder in due course, the Company shall execute, and an authorized signatory of
the Warrant Agent shall manually authenticate and deliver, in exchange for or in
lieu of the lost, stolen, destroyed, defaced or mutilated Warrant Certificate, a
new Warrant Certificate representing a like number of Warrants, bearing a number
or other distinguishing symbol not contemporaneously outstanding. The Company or
the Warrant Agent may require an indemnity bond that is sufficient in the
judgment of the Company and the Warrant Agent to protect the Company and the
Warrant Agent from any loss which any of them may suffer if a Warrant
Certificate is replaced. Upon the issuance of any new Warrant Certificate under
this Section in a name other than the prior registered holder of the lost,
stolen, destroyed, defaced or mutilated Warrant Certificate, the Company may
require the payment from the holder of such Warrant Certificate of a sum
sufficient to cover any tax, stamp tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Warrant Agent and the Registrar) in connection therewith. Every
substitute Warrant Certificate executed and delivered pursuant to this Section
in lieu of any lost, stolen or destroyed Warrant Certificate shall constitute an
additional contractual obligation of the Company, whether or not the lost,
stolen or destroyed Warrant Certificate shall be at any time enforceable by
anyone, and shall be entitled to the benefits of (but shall be subject to all
the limitations of rights set forth in) this Agreement equally and
proportionately with any and all other Warrant Certificates duly executed and
delivered hereunder. The provisions of this Section 1.09 are exclusive with
respect to the replacement of lost, stolen, destroyed, defaced or mutilated
Warrant Certificates and shall preclude (to the extent lawful) any and all other
rights or remedies notwithstanding any law or statute existing or hereafter
enacted to the contrary with respect to the replacement of lost, stolen,
destroyed, defaced or mutilated Warrant Certificates.

                  The Warrant Agent is hereby authorized to authenticate in
accordance with the provisions of this Agreement, and deliver the new Warrant
Certificates required pursuant to the provisions of this Section.

                  SECTION 1.10. Offices for Exercise, etc. So long as any of the
Warrants remain outstanding, the Company will designate and maintain in the
Borough of Manhattan, The City of New York: (a) an office or agency where the
Warrant Certificates may be presented for exercise, (b) an office or agency
where the Warrant Certificates may be presented for registration of transfer and
for exchange (including the exchange of temporary Warrant Certificates for
definitive Warrant Certificates pursuant to Section 1.05 hereof), and (c) an
office or agency where notices and demands to or upon the Company in respect of
the Warrants or of this Agreement may be served. The Company may from time to
time change or


<PAGE>
                                      -13-


rescind such designation, as it may deem desirable or expedient; provided,
however, that an office or agency shall at all times be maintained in the
Borough of Manhattan, The City of New York, as provided in the first sentence of
this Section. In addition to such office or offices or agency or agencies, the
Company may from time to time designate and maintain one or more additional
offices or agencies within or outside The City of New York, where Warrant
Certificates may be presented for exercise or for registration of transfer or
for exchange, and the Company may from time to time change or rescind such
designation, as it may deem desirable or expedient. The Company will give to the
Warrant Agent written notice of the location of any such office or agency and of
any change of location thereof. The Company hereby designates the Warrant Agent
at its corporate trust office identified at Four Albany Street, New York, New
York 10006 (the "Warrant Agent Office"), as the initial agency maintained for
each such purpose. In case the Company shall fail to maintain any such office or
agency or shall fail to give such notice of the location or of any change in the
location thereof, presentations and demands may be made and notice may be served
at the Warrant Agent Office and the Company appoints the Warrant Agent as its
agent to receive all such presentations, surrenders, notices and demands.

                  SECTION 1.11. Book-Entry Provisions for Global Warrants. (a)
The Global Warrants initially shall (i) be registered in the name of the
Depository or the nominee of such Depository, (ii) be delivered to the Warrant
Agent as custodian for such Depository and (iii) bear legends as set forth in
Exhibit B.

                  Members of, or participants in, the Depository
("Participants") shall have no rights under this Warrant Agreement with respect
to any Global Warrant held on their behalf by the Depository, or the Warrant
Agent as its custodian, or under the Global Warrant, and the Depository may be
treated by the Company, the Warrant Agent and any agent of the Company or the
Warrant Agent as the absolute owner of the Global Warrant for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Warrant Agent or any agent of the Company or the Warrant Agent from
giving effect to any written certification, proxy or other authorization
furnished by the Depository or impair, as between the Depository and
Participants, the operation of customary practices governing the exercise of the
rights of a beneficial owner in a Global Warrant.

                  (b) Transfers of Global Warrants shall be limited to transfers
in whole, but not in part, to the Depository, its successors or their respective
nominees. Interests of beneficial owners in the Global Warrants may be
transferred or exchanged for Definitive Warrants in accordance with the rules
and procedures of the Depository and the provisions of Section 1.08; provided,
however, that Definitive Warrants shall be transferred to all beneficial owners
in exchange for their beneficial interests in Global Warrants if (i) the
Depository notifies the Company that it is unwilling or unable to continue as
Depository for any Global Warrant and a successor Depository is not appointed by
the Company within 90 days of such notice,

<PAGE>
                                      -14-


(ii) the Company, at its option, notifies the Warrant Agent in writing that it
elects to cause the issuance of the Warrants as Definitive Warrants or (iii) an
Event of Default has occurred and is continuing and the Registrar has received a
request from the Depository to issue Definitive Warrants.

                  (c) In connection with any transfer or exchange of a portion
of the beneficial interest in a Global Warrant to beneficial owners pursuant to
paragraph (b), the Registrar shall (if one or more Definitive Warrants are to be
issued) reflect on its books and records the date and a decrease in the
principal amount of such Global Warrant in an amount equal to the principal
amount of the beneficial interest in the Global Warrant to be transferred, and
the Company shall execute, and the Warrant Agent shall authenticate and deliver,
one or more Definitive Warrants of like tenor and amount.

                  (d) In connection with the transfer of Global Warrants as an
entirety to beneficial owners pursuant to paragraph (b) of this Section 1.11,
the Global Warrants shall be deemed to be surrendered to the Warrant Agent for
cancellation, and the Company shall execute, and the Warrant Agent shall upon
written instructions from the Company authenticate and deliver, to each
beneficial owner identified by the Depository in exchange for its beneficial
interest in the Global Warrants, an equal aggregate principal amount of
Definitive Warrants of authorized denominations.

                  (e) Any Definitive Warrants constituting a Restricted Security
delivered in exchange for an interest in a Global Security pursuant to paragraph
(c) of this Section 1.11 shall, except as otherwise provided by Section 1.08,
bear the Private Placement Legend.

                  (f) The Holder of any Global Warrant may grant proxies and
otherwise authorize any Person, including Participants and Persons that may hold
interests through Participants, to take any action which a Holder is entitled to
take under this Warrant Agreement or the Warrants and the Warrant Agent is
entitled to rely upon any electronic instructions from beneficial owners to the
Holder of any Global Warrant.

                 DURATION, EXERCISE OF WARRANTS; EXERCISE PRICE
                           AND REPURCHASE OF WARRANTS

                  SECTION 2.01. Duration of Warrants. Subject to the terms and
conditions established herein, the Warrants shall expire at 5:00 p.m., New York
City time, on February 1, 2007. The applicable date of expiration of a
particular Warrant is referred to herein as the "Expiration Date" of such
Warrant. Each Warrant may be exercised on any

                                      -15-


Business Day (as defined below) on or after the Exercisability Date (as defined
in Section 2.02) and on or prior to the close of business on the Expiration
Date.

                  Any Warrant not exercised before the close of business on the
Expiration Date shall become void, and all rights of the holder under the
Warrant Certificate evidencing such Warrant and under this Agreement shall
cease.

                  "Business Day" shall mean any day on which (i) banks in New
York City, (ii) the principal U.S. securities exchange or market, if any, on
which any Common Stock is listed or admitted to trading and (iii) the principal
U.S. securities exchange or market, if any, on which the Warrants are listed or

shall have the right to purchase from the Company on or after the Exercisability
Date and on or prior to the close of business on the Expiration Date the number
of fully paid, registered and non-assessable shares of Common Stock specified in
Section 1.01, subject to adjustment in accordance with Article V hereof, at the
purchase price of $0.01 for each share purchased (the "Exercise Price"). The
number of Shares for which a particular Warrant may be exercised (the "Exercise
Rate") shall be subject to adjustment from time to time as set forth in Article
V hereof.

                  "Exercisability Date" means, with respect to each Warrant, the
date as of which an Exercise Event shall have occurred.

                  "Exercise Event" means, with respect to each Warrant, the date
of the occurrence of the earliest of: (1) an Initial Public Equity Offering, (2)
a class of equity securities of the Company is listed on a United States
national securities exchange or authorized for quotation on the Nasdaq National
Market or is otherwise subject to registration under the Exchange Act or (3) the
Separability Date. The Company will promptly notify the Warrant Agent of an
Exercise Event.

                  "Initial Public Equity Offering" means a primary public
offering (whether or not underwritten, but excluding any offering pursuant to
Form S-4 or Form S-8 under the Securities Act or any other publicly registered
offering pursuant to the Securities Act pertaining to an issuance of shares of
capital stock of the Company or securities exercisable therefor under any
benefit plan, employee compensation plan, or employee or director stock purchase
plan) of common stock of the Company pursuant to an effective registration

proceeds of at least $75 million.

<PAGE>

                                      -16-


                  "Registrable Securities" means any of (i) the Common Stock
issued and issuable upon exercise of the Warrants and (ii) any other securities
issued or issuable with respect to the Warrants or Shares by way of stock
dividend or stock split or in connection with a combination of shares,
recapitalization, merger, consolidation, reorganization or otherwise. As to any
particular Registrable Securities, such securities shall cease to be Registrable
Securities when (a) a registration statement with respect to the offering of
such securities by the holder thereof shall have been declared effective under
the Securities Act and such securities shall have been disposed of by such
holder pursuant to such registration statement, (b) such securities have been
sold to the public pursuant to, or are eligible for sale to the public without
volume or manner of sale restrictions under, Rule 144(k) (or any similar
provision then in force, but not Rule 144A) promulgated under the Securities
Act, (c) such securities shall have been otherwise transferred and new
certificates for such securities not bearing a legend restricting further
transfer shall have been delivered by the Company or its transfer agent and
subsequent disposition of such securities shall not require registration or
qualification under the Securities Act or any similar state law then in force or
(d) such securities shall have ceased to be outstanding.

                  "Person" means any individual, corporation, partnership,
limited liability company, joint venture, association, joint-stock company,
trust, unincorporated organization, government or any agency or political
subdivision thereof or any other entity, including any predecessor of any such
entity.

                  (b) Warrants may be exercised on or after the date they are
exercisable hereunder by (i) surrendering at any office or agency maintained for
that purpose by the Company pursuant to Section 1.10 (each a "Warrant Exercise
Office") the Warrant Certificate evidencing such Warrants with the form of
election to exercise Shares set forth on the reverse side of the Warrant
Certificate (the "Election to Exercise") duly completed and signed by the
registered holder or holders thereof or by the duly appointed legal
representative thereof or by a duly authorized attorney, and in the case of a
transfer, such signature shall be guaranteed by an eligible guarantor
institution, and (ii) paying in full the Exercise Price for each such Warrant
exercised. Each Warrant may be exercised only in whole. No exercise of Warrants
may be effected which does not call for the issuance of a number of shares of
Common Stock in direct proportion (subject only to rounding with respect to
fractional shares) to the aggregate number of shares of Common Stock then
issuable upon exercise of the Warrants evidenced by the relevant Warrant
Certificate.

                  (c) Simultaneously with the exercise of each Warrant, payment
in full of the aggregate Exercise Price may be made, at the option of the
holder, (i) by wire transfer or by certified check, (ii) by the surrender (which
surrender shall be evidenced by cancellation of the number of Warrants
represented by any Warrant Certificate presented in connection with a Cashless
Exercise) of a Warrant or Warrants (represented by one or more Warrant
Certifi-

<PAGE>

                                      -17-


cates), and without payment of the Exercise Price in cash, for such number of
Shares equal to the product of (1) the number of Shares for which such
Warrant is exercisable with payment in cash of the aggregate Exercise Price
as of the date of exercise and (2) the applicable Cashless Exercise Ratio or
(iii) with any combination of (i) and (ii). For purposes of this Agreement,
the "Cashless Exercise Ratio" shall equal a fraction, the numerator of which
is the excess of the Current Market Value per share of the Class A Common
Stock or Class H Common Stock, as applicable, on the date of exercise over
the Exercise Price per share as of the date of exercise and the denominator
of which is the Current Market Value per share of the Class A Common Stock or
Class H Common Stock, as applicable, on the date of exercise. An exercise of
a Warrant in accordance with the immediately preceding sentences is herein
called a "Cashless Exercise." Upon surrender of a Warrant Certificate
representing more than one Warrant in connection with the holder's option to
elect a Cashless Exercise, the number of Shares deliverable upon a Cashless
Exercise shall be equal to the Cashless Exercise Ratio multiplied by the
product of (a) the number of Warrants that the holder specifies is to be
exercised pursuant to a Cashless Exercise and (b) the number of Shares for
which such Warrant is then exercisable (without giving effect to the Cashless
Exercise option). All provisions of this Agreement shall be applicable with
respect to an exercise of a Warrant Certificate pursuant to a Cashless
Exercise for less than the full number of Warrants represented thereby. No
payment or adjustment shall be made on account of any dividends on the Shares
issued upon exercise of a Warrant. If the Company has not effected the
registration under the Securities Act of the offer and sale of the Shares by
the Company to the holders of the Warrants upon the exercise thereof, the
Company may elect to require that holders of the Warrants effect the exercise
of the Warrants solely pursuant to the Cashless Exercise option and may also
amend the Warrants to eliminate the requirement for payment of the Exercise
Price with respect such Cashless Exercise option. The Warrant Agent shall
have no obligation under this section to calculate the Cashless Exercise
Ratio. The Company shall calculate the Exercise Price and the Cashless
Exercise Ratio whenever such calculation is necessary and shall deliver an
Officers' Certificate to the Warrant Agent specifying such numbers.

                  (d) Upon such surrender of a Warrant Certificate and payment
and collection of the Exercise Price at any Warrant Exercise Office (other than
any Warrant Exercise Office that also is an office of the Warrant Agent), such
Warrant Certificate and payment shall be promptly delivered to the Warrant
Agent. The "Exercise Date" for a Warrant shall be the date when all of the items
referred to in the first sentence of paragraphs (b) and (c) of this Section 2.02
are received by the Warrant Agent at or prior to 11:00 a.m., New York City time,
on a Business Day and the exercise of the Warrants will be effective as of such
Exercise Date. If any items referred to in the first sentence of paragraphs (b)
and (c) are received after 11:00 a.m., New York City time, on a Business Day,
the exercise of the Warrants to which such item relates will be effective on the
next succeeding Business Day. Notwithstanding the foregoing, in the case of an
exercise of Warrants on the Expiration Date, if all of the items

<PAGE>
                                      -18-


referred to in the first sentence of paragraphs (b) and (c) are received by the
Warrant Agent at or prior to 5:00 p.m., New York City time, on the Expiration
Date, the exercise of the Warrants to which such items relate will be effective
on the Expiration Date.

                  (e) Upon the exercise of a Warrant in accordance with the
terms hereof, the receipt of a Warrant Certificate and payment of the Exercise
Price (or election of the Cashless Exercise option), the Warrant Agent shall:
(i) except to the extent exercise of the Warrant has been effected through
Cashless Exercise, cause an amount equal to the aggregate Exercise Price to be
paid to the Company by crediting the same to the account designated by the
Company in writing to the Warrant Agent for that purpose; (ii) advise the
Company immediately by telephone of the amount so deposited to the Company's
account and promptly confirm such telephonic advice in writing; and (iii) as
soon as practicable, advise the Company in writing of the number of Warrants
exercised in accordance with the terms and conditions of this Agreement and the
Warrant Certificates, the instructions of each exercising holder of the Warrant
Certificates with respect to delivery of the Shares to which such holder is
entitled upon such exercise, and such other information as the Company shall
reasonably request.

                  (f) Subject to Section 5.02 hereof, as soon as practicable
after the exercise of any Warrant or Warrants in accordance with the terms
hereof, the Company shall issue or cause to be issued to or upon the written
order of the registered holder of the Warrant Certificate evidencing such
exercised Warrant or Warrants, a certificate or certificates evidencing the
Shares to which such holder is entitled, in fully registered form, registered in
such name or names as may be directed by such holder pursuant to the Election to
Exercise, as set forth on the reverse of the Warrant Certificate. Such
certificate or certificates evidencing the Shares shall be deemed to have been
issued and any persons who are designated to be named therein shall be deemed to
have become the holder of record of such Shares as of the close of business on
the Exercise Date; the Shares may initially be issued in global form (the
"Global Shares"). Such Global Shares shall represent such of the outstanding
Shares as shall be specified therein and each shall provide that it shall
represent the aggregate amount of outstanding Shares from time to time endorsed
thereon and that the aggregate amount of outstanding Shares represented thereby
may from time to time be reduced or increased, as appropriate. Any endorsement
of a Global Share to reflect the amount of any increase or decrease in the
amount of outstanding Shares represented thereby shall be made by the registrar
for the Shares and the Depository (referred to below) in accordance with
instructions given by the holder thereof. The Depository Trust Company shall (if
possible) act as the Depository with respect to the Global Shares until a
successor shall be appointed by the Company and the registrar for the Shares.
After such exercise of any Warrant or Shares, the Company shall also issue or
cause to be issued to or upon the written order of the registered holder of such
Warrant Certificate, a new Warrant Certificate, countersigned by the Warrant
Agent pursuant to written instruction, evidencing the number of Warrants, if
any, remaining unexercised unless such Warrants shall have expired.

                                      -19-


                  SECTION 2.03. Cancellation of Warrant Certificates. In the
event the Company shall purchase or otherwise acquire Warrants, the Warrant
Certificates evidencing such Warrants may thereupon be delivered to the Warrant
Agent, and if so delivered, shall at the Company's written instruction be
canceled by it and retired. The Warrant Agent shall cancel all Warrant
Certificates properly surrendered for exchange, substitution, transfer or
exercise in accordance with its customary procedures.

                  SECTION 2.04. Notice of an Exercise Event. The Company shall,
as soon as practicable after the occurrence of an Exercise Event, send or cause
to be sent to each holder of Warrants, by first-class mail, at the addresses
appearing on the Warrant Register, a notice prepared by the Company advising
such holder of the Exercise Event which has occurred, which notice shall
describe the type of Exercise Event and the date of the occurrence thereof, as
applicable, and the date of expiration of the right to exercise the Warrants
prominently set forth in the face of such notice. The Company agrees to make
available the foregoing right notwithstanding any other provision herein to the
contrary.

                                   ARTICLE III

                          OTHER PROVISIONS RELATING TO
                          RIGHTS OF HOLDERS OF WARRANTS

                  SECTION 3.01. Enforcement of Rights. (a) Notwithstanding any
of the provisions of this Agreement, any holder of any Warrant Certificate,
without the consent of the Warrant Agent, the holder of any Shares or the holder
of any other Warrant Certificate, may, in and for his own behalf, enforce, and
may institute and maintain any suit, action or proceeding against the Company
suitable to enforce, his right to exercise the Warrant or Warrants evidenced by
his Warrant Certificate in the manner provided in such Warrant Certificate and
in this Agreement.

                  (b) Neither the Warrants nor any Warrant Certificate shall
entitle the holders thereof to any of the rights of a holder of Shares,
including, without limitation, the right to vote or to receive any dividends or
other payments or to consent or to receive notice as stockholders in respect of
the meetings of stockholders or for the election of directors of the Company or
any other matter, or any rights whatsoever as stockholders of the Company,
except as expressly provided herein (including Section 5.03 hereof).

                                   ARTICLE IV

                        CERTAIN COVENANTS OF THE COMPANY

                  SECTION 4.01. Payment of Taxes. The Company will pay all
documentary stamp taxes attributable to the initial issuance of Warrants and of
the Shares upon the exercise of Warrants; provided, however, that the Company
shall not be required to pay any tax or other governmental charge which may be
payable in respect of any transfer or exchange of any Warrant Certificates or
any certificates for Shares in a name other than the registered holder of a
Warrant Certificate surrendered upon the exercise of a Warrant. In any such
case, no transfer or exchange shall be made unless or until the person or
persons requesting issuance thereof shall have paid to the Company the amount of
such tax or other governmental charge or shall have established to the
satisfaction of the Company that such tax or other governmental charge has been
paid or an exemption is available therefrom.

                  SECTION 4.02. Rules 144 and 144A. The Company covenants that
it will file the reports required to be filed by it under the Securities Act and
the Exchange Act and the rules and regulations adopted by the Securities and
Exchange Commission thereunder in a timely manner in accordance with the
requirements of the Securities Act and the Exchange Act and, if at any time the
Company is not required to file such reports, it will, upon the request of any
holder or beneficial owner of Warrants, make available such information
necessary to permit sales pursuant to Rule 144A under the Securities Act.

                  SECTION 4.03. Form of Initial Public Equity Offering. The
Company agrees that it will not make an Initial Public Equity Offering of any
class of its Capital Stock (other than the class to which the Shares belong)
without amending the terms of the Company's certificate of incorporation to
provide that the Class A Common Stock is convertible into the class of Capital
Stock subject to the Initial Public Equity Offering (the "Subject Class") on a
share-for-share basis and that the rights, conditions and privileges of the
Subject Class shall not be adverse to the holders of the Class A Common Stock.

                  SECTION 4.04. Registration of Shares. The Company agrees that
it will comply with all applicable laws, including the Securities Act and any
applicable state securities laws, in connection with any offer and sale of
Common Stock (and other securities and property deliverable) upon exercise of
the Warrants.

                                    ARTICLE V

                                   ADJUSTMENTS

                  SECTION 5.01.     Adjustment of Exercise Rate; Notices.  The
Exercise Rate is subject to adjustment from time to time as provided in this
Section.

                  (a)     Adjustment for Change in Capital Stock.  If, after the
date hereof, the Company:

                   (i)    subdivides any of its outstanding shares of Common
         Stock into a greater number of shares;

                  (ii)    combines any of its outstanding shares of Common Stock
         into a smaller number of shares;

                 (iii)    pays a dividend or makes a distribution on any of its
         Common Stock in shares of any of its Capital Stock (as defined below)
         (other than Common Stock or rights, warrants or options for its Common
         Stock to the extent such issuance or distribution is covered by Section
         5.03); or

                  (iv)    issues by reclassification of any of its Common Stock
         any shares of any of its Capital Stock;

then the Exercise Rate in effect immediately prior to such action for each
Warrant then outstanding shall be adjusted so that the holder of a Warrant
thereafter exercised may receive the number of shares of Capital Stock of the
Company which such holder would have owned immediately following such action if
such holder had exercised the Warrant immediately prior to such action or
immediately prior to the record date applicable thereto, if any (regardless of
whether the Warrants then outstanding are then exercisable and without giving
effect to the Cashless Exercise option). If there are no outstanding shares of
Common Stock that are of the same class as the Shares at the time of any such
action and such action has therefore been taken only in respect of the Shares,
the adjustment shall relate to the Shares in their same form if it would not
frustrate the intent and purposes of this Section 5.01.

                  The adjustment shall become effective immediately after the
record date in the case of a dividend or distribution and immediately after the
effective date in the case of a subdivision, combination or reclassification. In
the event that such dividend or distribution is not so paid or made or such
subdivision, combination or reclassification is not effected, the Exercise Rate
shall again be adjusted to be the Exercise Rate which would then be in effect if
such record date or effective date had not been so fixed.

<PAGE>

                                      -22-


                  If after an adjustment a holder of a Warrant upon exercise of
such Warrant may receive shares of two or more classes of Capital Stock of the
Company, the Exercise Rate shall thereafter be subject to adjustment upon the
occurrence of an action taken with respect to any such class of Capital Stock as
is contemplated by this Article V with respect to the Common Stock, on terms
comparable to those applicable to Common Stock in this Article V.

                  (b) Adjustment for Sale of Common Stock Below Current Market
Value. If, after the date hereof, the Company grants or sells to any Affiliate
of the Company (other than a wholly-owned subsidiary) any Common Stock or any
securities convertible into or exchangeable or exercisable for any Common Stock
at a price below the then Current Market Value (other than (1) pursuant to the
exercise of the Warrants, (2) pursuant to any security convertible into, or
exchangeable or exercisable for shares of Common Stock outstanding as of the
date of this Agreement, (3) upon the conversion, exchange or exercise of any
convertible, exchangeable or exercisable security as to which upon the issuance
thereof an adjustment pursuant to this Article V has been made and (4) upon the
conversion, exchange or exercise of convertible, exchangeable or exercisable
securities of the Company outstanding on the date of this Agreement (to the
extent in accordance with the terms of such securities as in effect on the date
of this Agreement), the Exercise Rate for each Warrant then outstanding shall be
adjusted in accordance with the formula:

                     E' = E x     (O + N)
                               (O + (N x P/M))

where:

E'     =          the adjusted Exercise Rate for such class of Common Stock;

E      =          the then current Exercise Rate for such class of Common Stock;

O      =          the number of shares of such class of Common Stock
                  outstanding on a fully diluted basis immediately prior to the
                  sale of Common Stock or issuance of securities convertible,
                  exchangeable or exercisable for Common Stock;

N      =          the number of shares of such class of Common Stock so sold
                  or the maximum stated number of shares of Common Stock
                  issuable upon the conversion, exchange or exercise of any such
                  convertible, exchangeable or exercisable securities, as the
                  case may be;

P      =          the proceeds per share of Common Stock received by the
                  Company, which (i) in the case of shares of Common Stock is
                  the amount received by the Company in consideration for the
                  sale and issuance of such shares; and (ii) in the case of
                  securities convertible into or exchangeable or exercisable for
                  shares of

<PAGE>

                                      -23-


                  Common Stock is the amount received by the Company in
                  consideration for the sale and issuance of such convertible or
                  exchangeable or exercisable securities, plus the minimum
                  aggregate amount of additional consideration, other than the
                  surrender of such convertible or exchangeable securities,
                  payable to the Company upon exercise, conversion or exchange
                  thereof; and

M      =          the Current Market Value as of the Time of Determination or at
                  the time of sale, as the case may be.

                  The adjustment shall become effective immediately after the
record date for the determination of stockholders entitled to receive the
rights, warrants or options to which this paragraph (b) applies or upon
consummation of the sale of Common Stock, as the case may be. To the extent that
shares of Common Stock are not delivered after the expiration of such rights or
warrants, the Exercise Rate for each Warrant then outstanding shall be
readjusted to the Exercise Rate which would otherwise be in effect had the
adjustment made upon the issuance of such rights or warrants been made on the
basis of delivery of only the number of shares of Common Stock actually
delivered. In the event that such rights or warrants are not so issued, the
Exercise Rate for each Warrant then outstanding shall again be adjusted to be
the Exercise Rate which would then be in effect if such date fixed for
determination of stockholders entitled to receive such rights or warrants had
not been so fixed.

                  No adjustment shall be made under this paragraph (b) if the
application of the formula stated above in this paragraph (b) would result in a
value of E' that is lower than the value of E.

                  No adjustment in the Exercise Rate shall be made under this
paragraph (b) upon the conversion, exchange or exercise of options to acquire
shares of Common Stock by officers, directors, employees or consultants of the
Company; provided that the exercise price of such options, at the time of
issuance thereof, is at least equal to the then Current Market Value of the
Common Stock underlying such options.

                  "Affiliate" of any specified Person means any other Person
which, directly or indirectly, controls, is controlled by or is under direct or
indirect common control with such specified Person. For purposes of this
definition, "control" (including, with correlative meanings, the terms
"controlling," "controlled by" and "under common control with") when used with
respect to any Person means the power to direct the management and policies of
such Person, directly or indirectly, whether through the ownership of voting
securities, by contract or otherwise.

                  (c) Notice of Adjustment. Whenever the Exercise Rate is
adjusted, the Company shall promptly mail to holders of Warrants then
outstanding at the addresses appearing

<PAGE>

                                      -24-


on the Warrant Register a notice of the adjustment. The Company shall file with
the Warrant Agent and any other Registrar such notice and a certificate from the
Company's independent public accountants briefly stating the facts requiring the
adjustment and the manner of computing it. The certificate shall be conclusive
evidence that the adjustment is correct. Neither the Warrant Agent nor any such
Registrar shall be under any duty or responsibility with respect to any such
certificate except to exhibit the same during normal business hours to any
holder desiring inspection thereof.

                  (d) Reorganization of Company; Special Distributions. (i) If
the Company, in a single transaction or through a series of related
transactions, merges, consolidates or amalgamates with or into any other person
or sells, assigns, transfers, leases, conveys or otherwise disposes of all or
substantially all of its properties and assets to another person or group of
affiliated persons or is a party to a merger or binding share exchange which
reclassifies or changes its outstanding Common Stock (a "Fundamental
Transaction"), as a condition to consummating any such transaction the person
formed by or surviving any such consolidation or merger if other than the
Company or the person to whom such transfer has been made (the "Surviving
Person") shall enter into a supplemental warrant agreement. The supplemental
warrant agreement shall provide that the holder of a Warrant then outstanding
may exercise it for the kind and amount of securities, cash or other assets
which such holder would have received immediately after the Fundamental
Transaction if such holder had exercised the Warrant immediately before the
effective date of the transaction (regardless of whether the Warrants are then
exercisable and without giving effect to the Cashless Exercise option), assuming
(to the extent applicable) that such holder (i) was not a constituent person or
an affiliate of a constituent person to such transaction, (ii) made no election
with respect thereto, and (iii) was treated alike with the plurality of
non-electing holders.

                  (ii) Notwithstanding the foregoing, if the Company enters into
a Fundamental Transaction with another Person (other than a subsidiary of the
Company) and consideration is payable to holders of shares of Capital Stock (or
other securities or property) issuable or deliverable upon exercise of the
Warrants that are exercisable in exchange for their shares in connection with
such Fundamental Transaction which consists solely of cash, then the holders of
Warrants shall be entitled to receive distributions on the date of such event on
an equal basis with holders of such shares (or other securities issuable upon
exercise of the Warrants) as if the Warrants had been exercised immediately
prior to such event, less the Exercise Price therefor. Upon receipt of such
payment, if any, the rights of a holder of such a Warrant shall terminate and
cease and such holder's Warrants shall expire.

                 (iii) If this paragraph (d) applies, it shall supersede the
application of paragraph (a) of this Section 5.01.


<PAGE>

                                      -25-


                  (e) Company Determination Final. Any determination that the
Company or the Board of Directors of the Company must make pursuant to this
Article V is conclusive.

                  (f) Warrant Agent's Adjustment Disclaimer. The Warrant Agent
has no duty to determine when an adjustment under this Article V should be made,
how it should be made or what it should be. The Warrant Agent has no duty to
determine whether a supplemental warrant agreement under paragraph (f) need be
entered into or whether any provisions of any supplemental warrant agreement are
correct. The Warrant Agent shall not be accountable for and makes no
representation as to the validity or value of any securities or assets issued
upon exercise of Warrants. The Warrant Agent shall not be responsible for the
Company's failure to comply with this Article V.

                  (g) Adjustment for Tax Purposes. The Company may make such
increases in the Exercise Rate, in addition to those otherwise required by this
Section, as it considers to be advisable in order that any event treated for
Federal income tax purposes as a dividend of stock or stock rights shall not be
taxable to the recipients.

                  (h) Underlying Shares. The Company shall at all times reserve
and keep available, free from preemptive rights, out of its authorized but
unissued Common Stock or Common Stock held in the treasury of the Company, for
the purpose of effecting the exercise of Warrants, the full number of Shares
then deliverable upon the exercise of all Warrants then outstanding and payment
of the exercise price, and the shares so deliverable shall be fully paid and
nonassessable and free from all liens and security interests.

                  (i) Specificity of Adjustment. Irrespective of any adjustments
in the number or kind of shares purchasable upon the exercise of the Warrants,
Warrant Certificates theretofore or thereafter issued may continue to express
the same number and kind of Shares per Warrant as are stated on the Warrant
Certificates initially issuable pursuant to this Agreement.

                  (j) Voluntary Adjustment. The Company from time to time may
increase the Exercise Rate by any number and for any period of time (provided
that such period is not less than 20 Business Days). Whenever the Exercise Rate
is so increased, the Company shall mail to holders at the addresses appearing on
the Warrant Register and file with the Warrant Agent a notice of the increase.
The Company shall give the notice at least 15 days before the date the increased
Exercise Rate takes effect. The notice shall state the increased Exercise Rate
and the period it will be in effect. A voluntary increase in the Exercise Rate
does not change or adjust the Exercise Rate otherwise in effect as determined by
this Section 5.01.

                  (k) Multiple Adjustments. After an adjustment to the Exercise
Rate for outstanding Warrants under this Article V, any subsequent event
requiring an adjustment under


<PAGE>                                      -26-


this Article V shall cause an adjustment to the Exercise Rate for outstanding
Warrants as so adjusted.

                  (l)  Definitions.

                  "Capital Stock" means, with respect to any person, any and all
shares, interests, participations, rights in, or other equivalents (however
designated and whether voting or non-voting) of, such person's capital stock,
whether outstanding on the Issue Date (as defined in the Indenture) or issued
after the Issue Date, and any and all rights, warrants or options exchangeable
for or convertible into such capital stock.

                  "Current Market Value" per share of Common Stock of the
Company or any other security at any date means (i) if the security is not
registered under the Exchange Act, the fair market value of the security,
determined in good faith by the Board of Directors of the Company if the
aggregate amount of such security to be issued is less than or equal to $50.0
million, or if the aggregate amount of such security exceeds $50.0 million, as
determined by an Independent Financial Expert (provided that, in the case of the
calculation of Current Market Value for determining the cash value of fractional
shares, any such determination within six months that is, in the good faith
judgment of the Board, a reasonable determination of value, may be utilized) or
(ii) (a) if the security is registered under the Exchange Act, the average of
the daily closing sales prices of the securities for the 20 consecutive days
immediately preceding such date, or (b) if the security has been registered
under the Exchange Act for less than 20 consecutive days immediately preceding
such date, then the offering price of the security in the transaction causing
registration under the Exchange Act, in the case of each of (ii)(a) and (ii)(b),
as certified to the Warrant Agent by the President, any Vice President or the
Chief Financial Officer of the Company. The closing sales price for each such
trading day shall be: (A) in the case of a security listed or admitted to
trading on any United States national securities exchange or quotation system,
the closing sales price, regular way, on such day, or if no sale takes place on
such day, the average of the closing bid and asked prices on such day, (B) in
the case of a security not then listed or admitted to trading on any United
States national securities exchange or quotation system, the last reported sale
price on such day, or if no sale takes place on such day, the average of the
closing bid and asked prices on such day, as reported by a reputable quotation
source designated by the Company, (C) in the case of a security not then listed
or admitted to trading on any United States national securities exchange or
quotation system and as to which no such reported sale price or bid and asked
prices are available, the average of the reported high bid and low asked prices
on such day, as reported by a reputable quotation service, or a newspaper of
general circulation in the Borough of Manhattan, City and State of New York
customarily published on each Business Day, designated by the Company, or, if
there shall be no bid and asked prices on such day, the average of the high bid
and low asked prices, as so reported, on the most recent day (not more than 30
days prior to the date in question) for which prices have been so reported and
(D) if

<PAGE>
                                      -27-


there are not bid and asked prices reported during the 30 days prior to the date
in question, the Current Market Value shall be determined as if the Shares (or
other securities) were not registered under the Exchange Act.

                  "Independent Financial Expert" means a United States
investment banking firm of national or regional standing in the United States
(i) which does not, and whose directors, officers and employees or Affiliates do
not have a direct or indirect material financial interest for its proprietary
account in the Company or any of its Affiliates and (ii) which, in the judgment
of the Board of Directors of the Company, is otherwise independent with respect
to the Company and its Affiliates and qualified to perform the task for which it
is to be engaged.

                  "Time of Determination" means, (i) in the case of any
distribution of securities or other property to existing stockholders to which
paragraph (b) applies, the time and date of the determination of stockholders
entitled to receive such securities or property or (ii) in the case of any other
issuance and sale to which paragraph (b) applies, the time and date of such
issuance or sale.

                  (m) When De Minimis Adjustment may be Deferred. No adjustment
in the Exercise Rate need be made unless the adjustment would require an
increase of at least 1% in the Exercise Rate. Any adjustments that are not made
shall be carried forward and taken into account in any subsequent adjustments.
All calculations under this Section 5 shall be made to the nearest 1/1000th of a
share, as the case may be.

                  SECTION 5.02. Fractional Shares. The Company will not be
required to issue fractional Shares upon exercise of the Warrants or distribute
Share certificates that evidence fractional Shares. In the event a holder is
required by Section 2.02(c) to make a Cashless Exercise, and the Company
determines not to issue fractional Shares, the number of Shares issuable shall
be rounded up to the nearest whole number. In addition, in no event shall any
holder of Warrants be required to make any payment of a fractional cent. In lieu
of fractional Shares, the Company may pay to the registered holders of Warrant
Certificates at the time Warrants evidenced thereby are exercised as herein
provided an amount in cash equal to the same fraction of the Current Market
Value, per Share on the Business Day preceding the date the Warrant Certificates
evidencing such Warrants are surrendered for exercise. Such payments will be
made by check or by transfer to an account maintained by such registered holder
with a bank in The City of New York. If any holder surrenders for exercise more
than one Warrant Certificate, the number of Shares deliverable to such holder
may, at the option of the Company, be computed on the basis of the aggregate
amount of all the Warrants exercised by such holder.

                  SECTION 5.03. Certain Distributions. If at any time the
Company grants, issues or sells options, convertible securities, or rights to
purchase Capital Stock, warrants or other securities pro rata to the record
holders of any Common Stock (the "Distribution Rights") or, without duplication,
makes any dividend or otherwise makes any distribution, including, subject to
applicable law, pursuant to any plan of liquidation but excluding dividends and
distributions permitted by clauses (7), (8), (9), (10) and (11) of the third
paragraph of Section 4.11 of the Indenture, but, in the case of (10), only to
the extent such payments are not paid as dividends or distributions to Heat
Holding Corp.'s equity holders ("Distribution") on Common Stock (whether in
cash, property, evidences of indebtedness or otherwise), then the Company shall
grant, issue, sell or make to each registered holder of Warrants then
outstanding, the aggregate Distribution Rights or Distribution, as the case may
be, which such holder would have acquired if such holder had held the maximum
number of Shares acquirable upon complete exercise of such holder's Warrants
(regardless of whether the Warrants are then exercisable and without giving
effect to the Cashless Exercise option) immediately before the record date for
the grant, issuance or sale of such Distribution Rights or Distribution, as the
case may be, or, if there is no such record date, the date as of which the
record holders of Common Stock are to be determined for the grant, issue or sale
of such Distribution Rights or Distribution, as the case may be.

                                   ARTICLE VI

                          CONCERNING THE WARRANT AGENT

            SECTION 6.01. Warrant Agent. The Company hereby appoints
Bankers Trust Company as Warrant Agent of the Company in respect of the Warrants
and the Warrant Certificates upon the terms and subject to the conditions herein
and in the Warrant Certificates set forth; and Bankers Trust Company hereby
accepts such appointment. The Warrant Agent shall have the powers and authority
specifically granted to and conferred upon it in the Warrant Certificates and
hereby and such further powers and authority to act on behalf of the Company as
the Company may hereafter grant to or confer upon it and it shall accept in
writing. All of the terms and provisions with respect to such powers and
authority contained in the Warrant Certificates are subject to and governed by
the terms and provisions hereof. The Warrant Agent may act through agents and
shall not be responsible for the misconduct or negligence of any such agent
appointed with due care.

                  SECTION 6.02. Conditions of Warrant Agent's Obligations. The
Warrant Agent accepts its obligations herein set forth upon the terms and
conditions hereof and in the Warrant Certificates, including the following, to
all of which the Company agrees and to all of which the rights hereunder of the
holders from time to time of the Warrant Certificates shall be subject:

<PAGE>
                                      -29-


                  (a) The Warrant Agent shall be entitled to compensation to be
         agreed upon with the Company in writing for all services rendered by it
         and the Company agrees promptly to pay such compensation and to
         reimburse the Warrant Agent for its reasonable out-of-pocket expenses
         (including reasonable fees and expenses of counsel) incurred without
         gross negligence or willful misconduct on its part in connection with
         the services rendered by it hereunder. The Company also agrees to
         indemnify the Warrant Agent and any predecessor Warrant Agent, their
         directors, officers, affiliates, agents and employees for, and to hold
         them and their directors, officers, affiliates, agents and employees
         harmless against, any loss, liability or expense of any nature
         whatsoever (including, without limitation, reasonable fees and expenses
         of counsel) incurred without gross negligence or willful misconduct on
         the part of the Warrant Agent, arising out of or in connection with its
         acting as such Warrant Agent hereunder and its exercise of its rights
         and performance of its obligations hereunder. The obligations of the
         Company under this Section 6.02 shall survive the exercise and the
         expiration of the Warrant Certificates and the resignation and removal
         of the Warrant Agent.

                  (b) In acting under this Agreement and in connection with the
         Warrant Certificates, the Warrant Agent is acting solely as agent of
         the Company and does not assume any obligation or relationship of
         agency or trust for or with any of the owners or holders of the Warrant
         Certificates.

                  (c) The Warrant Agent may consult with counsel of its
         selection and any advice or written opinion of such counsel shall be
         full and complete authorization and protection in respect of any action
         taken, suffered or omitted by it hereunder in good faith and in
         accordance with such advice or opinion.

                  (d) The Warrant Agent shall be fully protected and shall incur
         no liability for or in respect of any action taken or omitted to be
         taken or thing suffered by it in reliance upon any Warrant Certificate,
         notice, direction, consent, certificate, affidavit, opinion of counsel,
         instruction, statement or other paper or document reasonably believed
         by it to be genuine and to have been presented or signed by the proper
         parties.

                  (e) The Warrant Agent, and its officers, directors, affiliates
         and employees ("Related Parties"), may become the owners of, or acquire
         any interest in, Warrant Certificates, shares or other obligations of
         the Company with the same rights that it or they would have it if were
         not the Warrant Agent hereunder and, to the extent permitted by
         applicable law, it or they may engage or be interested in any financial
         or other transaction with the Company and may act on, or as Depository,
         trustee or agent for, any committee or body of holders of shares or
         other obligations of the Company as freely as if it were not the
         Warrant Agent hereunder. Nothing in this Agreement shall

<PAGE>
                                      -30-


          be deemed to prevent the Warrant Agent or such Related Parties from
          acting in any other capacity for the Company.

                  (f) The Warrant Agent shall not be under any liability for
         interest on, and shall not be required to invest, any monies at any
         time received by it pursuant to any of the provisions of this Agreement
         or of the Warrant Certificates.

                  (g) The Warrant Agent shall not be under any responsibility in
         respect of the validity of this Agreement (or any term or provision
         hereof) or the execution and delivery hereof (except the due execution
         and delivery hereof by the Warrant Agent) or in respect of the validity
         or execution of any Warrant Certificate (except its authentication
         thereof).

                  (h) The recitals and other statements contained herein and in
         the Warrant Certificates (except as to the Warrant Agent's
         authentication thereon) shall be taken as the statements of the Company
         and the Warrant Agent assumes no responsibility for the correctness of
         the same. The Warrant Agent does not make any representation as to the
         validity or sufficiency of this Agreement or the Warrant Certificates,
         except for its due execution and delivery of this Agreement; provided,
         however, that the Warrant Agent shall not be relieved of its duty to
         authenticate the Warrant Certificates as authorized by this Agreement.
         The Warrant Agent shall not be accountable for the use or application
         by the Company of the proceeds of the exercise of any Warrant.

                  (i) Before the Warrant Agent acts or refrains from acting with
         respect to any matter contemplated by this Warrant Agreement, it may
         require:

                           (1) an Officers' Certificate (as defined in the
                  Indenture) stating on behalf of the Company that, in the
                  opinion of the signers, all conditions precedent, if any,
                  provided for in this Warrant Agreement relating to the
                  proposed action have been complied with; and

                           (2) if reasonably necessary in the sole judgment of
                  the Warrant Agent, an opinion of counsel for the Company
                  stating that, in the opinion of such counsel, all such
                  conditions precedent have been complied with provided that
                  such matter is one customarily opined on by counsel.

                  Each Officers' Certificate or, if requested, an opinion of
         counsel with respect to compliance with a condition or covenant
         provided for in this Warrant Agreement shall include:

                           (1)  a statement that the person making such
                  certificate or opinion has read such covenant or condition;

<PAGE>                                      -31-


                           (2)  a brief statement as to the nature and scope of
                  the examination or investigation upon which the statements or
                  opinions contained in such certificate or opinion are based;

                           (3)  a statement that, in the opinion of such person,
                  he or she has made such examination or investigation as is
                  necessary to enable him or her to express an informed opinion
                  as to whether or not such covenant or condition has been
                  complied with; and

                           (4)  a statement as to whether or not, in the opinion
                  of such person, such condition or covenant has been complied
                  with.

                  (j) The Warrant Agent shall be obligated to perform such
         duties as are herein and in the Warrant Certificates specifically set
         forth and no implied duties or obligations shall be read into this
         Agreement or the Warrant Certificates against the Warrant Agent. The
         Warrant Agent shall not be accountable or under any duty or
         responsibility for the use by the Company of any of the Warrant
         Certificates authenticated by the Warrant Agent and delivered by it to
         the Company pursuant to this Agreement. The Warrant Agent shall have no
         duty or responsibility in case of any default by the Company in the
         performance of its covenants or agreements contained in the Warrant
         Certificates or in the case of the receipt of any written demand from a
         holder of a Warrant Certificate with respect to such default,
         including, without limiting the generality of the foregoing, any duty
         or responsibility to initiate or attempt to initiate any proceedings at
         law or otherwise or, except as provided in Section 7.02 hereof, to make
         any demand upon the Company.

                  (k) Unless otherwise specifically provided herein, any order,
         certificate, notice, request, direction or other communication from the
         Company made or given under any provision of this Agreement shall be
         sufficient if signed by its chairman of the Board of Directors, its
         president, its treasurer, its controller or any vice president or its
         secretary or any assistant secretary.

                  (l) The Warrant Agent shall have no responsibility in respect
         of any adjustment pursuant to Article V hereof.

                  (m) the Company agrees that it will perform, execute,
         acknowledge and deliver, or cause to be performed, executed,
         acknowledged and delivered, all such further and other acts,
         instruments and assurances as may reasonably be required by the Warrant
         Agent for the carrying out or performing by the Warrant Agent of the
         provisions of this Agreement.

                                      -32-


                  (n) The Warrant Agent is hereby authorized and directed to
         accept written instructions with respect to the performance of its
         duties hereunder from any one of the chairman of the Board of
         Directors, the president, the treasurer, the controller, any vice
         president or the secretary or assistant secretary of the Company or any
         other officer or official of the Company reasonably believed to be
         authorized to give such instructions and to apply to such officers or
         officials for advice or instructions in connection with its duties, and
         it shall not be liable for any action taken or suffered to be taken by
         it in good faith in accordance with instructions with respect to any
         matter arising in connection with the Warrant Agent's duties and
         obligations arising under this Agreement. Such application by the
         Warrant Agent for written instructions from the Company may, at the
         option of the Warrant Agent, set forth in writing any action proposed
         to be taken or omitted by the Warrant Agent with respect to its duties
         or obligations under this Agreement and the date on or after which such
         action shall be taken and the Warrant Agent shall not be liable for any
         action taken or omitted in accordance with a proposal included in any
         such application on or after the date specified therein (which date
         shall be not less than 10 Business Days after the Company receives such
         application unless the Company consents to a shorter period), provided
         that (i) such application includes a statement to the effect that it is
         being made pursuant to this paragraph (n) and that unless objected to
         prior to such date specified in the application, the Warrant Agent will
         not be liable for any such action or omission to the extent set forth
         in such paragraph (n) and (ii) prior to taking or omitting any such
         action, the Warrant Agent has not received written instructions
         objecting to such proposed action or omission.

                  (o) Whenever in the performance of its duties under this
         Agreement the Warrant Agent shall deem it necessary or desirable that
         any fact or matter be proved or established by the Company prior to
         taking or suffering any action hereunder, such fact or matter (unless
         other evidence in respect thereof be herein specifically prescribed)
         may be deemed to be conclusively proved and established by a
         certificate signed on behalf of the Company by any one of the chairman
         of the Board of Directors, the president, the treasurer, the
         controller, any vice president or the secretary or assistant secretary
         of the Company or any other officer or official of the Company
         reasonably believed to be authorized to give such instructions and
         delivered to the Warrant Agent; and such certificate shall be full
         authorization to the Warrant Agent for any action taken or suffered in
         good faith by it under the provisions of this Agreement in reliance
         upon such certificate.

                  (p) The Warrant Agent shall not be required to risk or expend
         its own funds in the performance of its obligations and duties
         hereunder.

                  SECTION 6.03.     Resignation and Appointment of Successor.
(a) The Company agrees, for the benefit of the holders from time to time of the
Warrant Certificates, that there shall at all times be a Warrant Agent
hereunder.

                  (b) The Warrant Agent may at any time resign as Warrant Agent
by giving written notice to the Company of such intention on its part,
specifying the date on which its desired resignation shall become effective;
provided, however, that such date shall be at least 30 days after the date on
which such notice is given unless the Company agrees to accept less notice. Upon
receiving such notice of resignation, the Company shall promptly appoint a
successor Warrant Agent, qualified as provided in Section 6.03(d) hereof, by
written instrument in duplicate signed on behalf of the Company, one copy of
which shall be delivered to the resigning Warrant Agent and one copy to the
successor Warrant Agent. As provided in Section 6.03(d) hereof, such resignation
shall become effective upon the earlier of (x) the acceptance of the appointment
by the successor Warrant Agent or (y) 30 days after receipt by the Company of
notice of such resignation. The Company may, at any time and for any reason, and
shall, upon any event set forth in the next succeeding sentence, remove the
Warrant Agent and appoint a successor Warrant Agent by written instrument in
duplicate, specifying such removal and the date on which it is intended to
become effective, signed on behalf of the Company, one copy of which shall be
delivered to the Warrant Agent being removed and one copy to the successor
Warrant Agent. The Warrant Agent shall be removed as aforesaid if it shall
become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a
receiver of the Warrant Agent or of its property shall be appointed, or any
public officer shall take charge or control of it or of its property or affairs
for the purpose of rehabilitation, conservation or liquidation. Any removal of
the Warrant Agent and any appointment of a successor Warrant Agent shall become
effective upon acceptance of appointment by the successor Warrant Agent as
provided in Section 6.03(d). As soon as practicable after appointment of the
successor Warrant Agent, the Company shall cause written notice of the change in
the Warrant Agent to be given to each of the registered holders of the Warrants
in the manner provided for in Section 8.04 hereof.

                  (c) Upon resignation or removal of the Warrant Agent, if the
Company shall fail to appoint a successor Warrant Agent within a period of 60
days after receipt of such notice of resignation or removal, then the holder of
any Warrant Certificate or the retiring Warrant Agent may apply to a court of
competent jurisdiction for the appointment of a successor to the Warrant Agent.
Pending appointment of a successor to the Warrant Agent, either by the Company
or by such a court, the duties of the Warrant Agent shall be carried out by the
Company.

                  (d) Any successor Warrant Agent, whether appointed by the
Company or by a court, shall be a bank or trust company in good standing,
incorporated under the laws of the United States of America or any State thereof
and having, at the time of its appointment, a

<PAGE>
                                      -34-


combined capital surplus of at least $250 million. Such successor Warrant
Agent shall execute and deliver to its predecessor and to the Company an
instrument accepting such appointment hereunder and all the provisions of this
Agreement, and thereupon such successor Warrant Agent, without any further act,
deed or conveyance, shall become vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as Warrant Agent hereunder, and such predecessor shall thereupon become
obligated to (i) transfer and deliver, and such successor Warrant Agent shall be
entitled to receive, all securities, records or other property on deposit with
or held by such predecessor as Warrant Agent hereunder and (ii) upon payment of
the amounts then due it pursuant to Section 6.02(a) hereof, pay over, and such
successor Warrant Agent shall be entitled to receive, all monies deposited with
or held by any predecessor Warrant Agent hereunder.

                  (e) Any corporation or bank into which the Warrant Agent
hereunder may be merged or converted, or any corporation or bank with which the
Warrant Agent may be consolidated, or any corporation or bank resulting from any
merger, conversion or consolidation to which the Warrant Agent shall be a party,
or any corporation or bank to which the Warrant Agent shall sell or otherwise
transfer all or substantially all of its corporate trust business, shall be the
successor to the Warrant Agent under this Agreement (provided that such
corporation or bank shall be qualified as aforesaid) without the execution or
filing of any document or any further act on the part of any of the parties
hereto.

                  (f) No Warrant Agent under this Warrant Agreement shall be
personally liable for any action or omission of any successor Warrant Agent.

                                   ARTICLE VII

                                  MISCELLANEOUS

                  SECTION 7.01.     Amendment. This Agreement and the terms
of the Warrants may be amended by the Company and the Warrant Agent, without
the consent of the holder of any Warrant Certificate, for the purpose of
curing any ambiguity, or of curing, correcting or supplementing any defective
or inconsistent provision contained herein or therein, or to effect any
assumptions of the Company's obligations hereunder and thereunder by a
successor corporation under the circumstances described in Section 5.01(d)
hereof or in any other manner which the Company may deem necessary or
desirable and which shall not adversely affect the interests of the holders
of the Warrant Certificates.

                  The Company and the Warrant Agent may amend, modify or
supplement this Agreement and the terms of the Warrants, and waivers to
departures from the terms hereof and thereof may be given, with the consent of
the Requisite Warrant Holders (as defined below) for the purpose of adding any
provision to or changing in any manner or eliminating any

<PAGE>
                                      -35-


of the provisions of this Agreement or modifying in any manner the rights of the
holders of the outstanding Warrants; provided, however, that no such
modification that increases the Exercise Price or decreases the Exercise Rate,
makes any change to the last paragraph of Section 5.01(d), reduces the period of
time during which the Warrants are exercisable hereunder, or effects any change
to this Section 7.01 may be made with respect to any Warrant without the consent
of the holder of such Warrant. "Requisite Warrant Holders" means (i) in the case
of any amendment, modification, supplement or waiver affecting Warrant Holders,
the holders of a majority in number of the outstanding Warrants so affected, or
(ii) in the case of any amendment, modification, supplement or waiver affecting
Warrant Holders, a majority in number of Shares represented by the Warrants that
would be issuable assuming exercise thereof at the time such amendment,
modification, supplement or waiver is voted upon. Notwithstanding any other
provision of this Agreement, the Warrant Agent's consent must be obtained
regarding any supplement or amendment which alters the Warrant Agent's rights or
duties (it being expressly understood that the foregoing shall not be in
derogation of the right of the Company to remove the Warrant Agent in accordance
with Section 6.03 hereof). For purposes of any amendment, modification or waiver
hereunder, Warrants held by the Company or any of its Affiliates shall be
disregarded.

                  Any modification or amendment made in accordance with this
Agreement will be conclusive and binding on all present and future holders of
Warrant Certificates whether or not they have consented to such modification or
amendment or waiver and whether or not notation of such modification or
amendment is made upon such Warrant Certificates. Any instrument given by or on
behalf of any holder of a Warrant Certificate in connection with any consent to
any modification or amendment will be conclusive and binding on all subsequent
holders of such Warrant Certificate.

                  SECTION 7.02.    Notices and Demands to the Company and
Warrant Agent. If the Warrant Agent shall receive any notice or demand
addressed to the Company by the holder of a Warrant Certificate pursuant to
the provisions hereof or of the Warrant Certificates, the Warrant Agent shall
promptly forward such notice or demand to the Company.

                  SECTION 7.03.    Addresses for Notices to Parties and for
Transmission of Documents. All notices hereunder to the parties hereto shall
be deemed to have been given when sent by certified or registered mail,
postage prepaid, or by facsimile transmission, confirmed by first class mail,
postage prepaid, addressed to any party hereto as follows:

                               WARRANT CERTIFICATE

                        AAVID THERMAL TECHNOLOGIES, INC.

                  This Warrant Certificate certifies that [  ], or registered
assigns, is the registered holder of [ ] Warrants (the "Warrants") to purchase
shares of Class A Common Stock, par value $0.0001 per share (the "Class A Common
Stock"), and shares of Class H Common Stock, par value $0.0001 per share (the
"Class H Common Stock", together with the Class A Common Stock, the "Common
Stock") of AAVID THERMAL TECHNOLOGIES, INC., a Delaware corporation (the
"Company", which term includes its successors and assigns). Each Warrant
entitles the holder to purchase from the Company at any time from 9:00 a.m. New
York City time on or after the Exercisability Date until 5:00 p.m., New York
City time, on February 1, 2007 (the "Expiration Date"), [ ] fully paid,
registered and non-assessable shares of Class A Common Stock and [ ] fully paid,
registered and non-assessable shares of Class H Common Stock, in each case
subject to adjustment as provided in Article V of the Warrant Agreement, at the
exercise price of $0.01 for each share purchased (the "Exercise Price") (the
shares of Common Stock purchasable upon exercise of a Warrant being herein
referred to as the "Shares" and, unless the context otherwise requires, such
term shall also mean the other securities or property purchasable and
deliverable upon exercise of a Warrant as provided in the Warrant Agreement),
upon surrender of this Warrant Certificate and payment of the Exercise Price (i)
by wire transfer or certified check, (ii) pursuant to the next sentence or (iii)
in any combination of (i) and (ii), at any office or agency maintained for that
purpose by the Company (the "Warrant Agent Office"), subject to the conditions
set forth herein and in the Warrant Agreement. A Warrant may also be exercised
solely by the surrender of the Warrant, and without the payment of the Exercise
Price in cash, for such number of Shares equal to the product of (1) the number
of Shares for which such Warrant is exercisable with payment of the Exercise
Price as of the date of exercise and (2) the Cashless Exercise Ratio. For
purposes of this Warrant, the "Cashless Exercise Ratio" shall equal a fraction,
the numerator of which is the excess of the Current Market Value per share of
the Common Stock on the date of exercise over the Exercise Price per share as of
the date of exercise and the denominator of which is the Current Market Value
per share of the Common Stock on the date of exercise. An exercise of a Warrant
in accordance with the immediately preceding sentences is herein called a
"Cashless Exercise." Upon surrender of a Warrant Certificate representing more
than one Warrant in connection with the Holder's option to elect a Cashless
Exercise, the number of Shares deliverable upon a Cashless Exercise shall be
equal to the Cashless Exercise Ratio multiplied by the product of (a) the number
of Warrants that the holder specifies is to be exercised pursuant to a Cashless
Exercise and (b) the number of Shares for which such Warrant is then exercisable
(without giving effect to the Cashless Exercise Option). If the Company has not
effected the registration under the Securities Act of the

                                      A- 3

<PAGE>

offer and sale of the Shares by the Company to the holders of the Warrants upon
the exercise thereof, the Company may elect to require that holders of the
Warrants effect the exercise of the Warrants solely pursuant to the Cashless
Exercise option and may also amend the Warrants to eliminate the requirement for
payment of the Exercise Price with respect to such Cashless Exercise option. All
provisions of the Warrant Agreement shall be applicable with respect to an
exercise of a Warrant Certificate pursuant to a Cashless Exercise for less than
the full number of Warrants represented thereby. Capitalized terms used herein
without being defined herein shall have the definitions ascribed to such terms
in the Warrant Agreement.

                  "Current Market Value" per share of Common Stock of the
Company or any other security at any date means (i) if the security is not
registered under the Exchange Act, (a) the fair market value of the security,
determined in good faith by the Board of Directors of the Company if the
aggregate amount of such security to be issued is less than or equal to $20.0
million, or if the aggregate amount of such security exceeds $20.0 million, as
determined by an Independent Financial Expert (provided that, in the case of the
calculation of Current Market Value for determining the cash value of fractional
shares, any such determination within six months that is, in the good faith
judgment of the Board, a reasonable determination of value, may be utilized) or
(ii) (a) if the security is registered under the Exchange Act, the average of
the daily closing sales prices of the securities for the 20 consecutive trading
days immediately preceding such date, or (b) if the security has been registered
under the Exchange Act for less than 20 consecutive trading days before such
date, then the average of the closing sales prices for all of the trading days
before such date for which closing sales prices are available, in the case of
each of (ii)(a) and (ii)(b), as certified to the Warrant Agent by the President,
any Vice President or the Chief Financial Officer of the Company. The closing
sales price for each such trading day shall be: (A) in the case of a security
listed or admitted to trading on any United States national securities exchange
or quotation system, the closing sales price, regular way, on such day, or if no
sale takes place on such day, the average of the closing bid and asked prices on
such day, (B) in the case of a security not then listed or admitted to trading
on any United States national securities exchange or quotation system, the last
reported sale price on such day, or if no sale takes place on such day, the
average of the closing bid and asked prices on such day, as reported by a
reputable quotation source designated by the Company, (C) in the case of a
security not then listed or admitted to trading on any United States national
securities exchange or quotation system and as to which no such reported sale
price or bid and asked prices are available, the average of the reported high
bid and low asked prices on such day, as reported by a reputable quotation
service, or a newspaper of general circulation in the Borough of Manhattan, City
and State of New York customarily published on each Business Day, designated by
the Company, or, if there shall be no bid and asked prices on such day, the
average of the high bid and low asked prices, as so reported, on the most recent
day (not more than 30 days prior to the date in question) for which prices have
been so reported and (D) if there are not bid and asked prices reported during
the 30 days prior to the date in question, the Current Market Value shall be
determined as if the Shares (or other securities) were not registered under the
Exchange Act.

                  "Exercise Event" means, with respect to each Warrant, the date
of the occurrence of the earliest of: (1) an Initial Public Equity Offering (as
defined in the Warrant Agreement), (2) a class of equity securities of the
Company is listed on a national securities exchange or authorized for quotation
on the Nasdaq National Market or is otherwise subject to registration under the
Exchange Act or (3) the Separability Date.

                  "Independent Financial Expert" means a United States
investment banking firm of national or regional standing, (i) which does not,
and whose directors, officers and employees or Affiliates do not have a direct
or indirect material financial interest for its proprietary account in the
Company or any of its Affiliates and (ii) which, in the judgment of the Board of
Directors of the Company, is otherwise independent with respect to the Company
and its Affiliates and qualified to perform the task for which it is to be
engaged.

                  "Separability Date" shall mean the earliest to occur of: (1)
180 days after the Issue Date (as defined in the Indenture); (2) the occurrence
of a Change of Control (as defined in the Indenture); (3) the occurrence of an
Event of Default (as defined in the Indenture); (4) the effectiveness of a
registration statement under the Securities Act of 1933, as amended (the
"Securities Act") with respect to the Notes or the Exchange Notes (as defined in
the Indenture); or (5) such earlier date as determined by CIBC in its discretion
and specified to the Company, the Trustee and the Warrant Agent in writing. The
separation of the Warrants and the Notes is herein referred to as a
"Separation."

                  No exercise of the Warrants may be effected which does not
call for the issuance of a number of shares of Common Stock in direct proportion
(subject only to rounding with respect to fractional shares) to the aggregate
number of shares of Common Stock then issuable upon exercise of the Warrants
evidenced hereby.

                  The Company has initially designated the principal corporate
trust office of the Warrant Agent in the Borough of Manhattan, The City of New
York, as the initial Warrant Agent Office. The number of Shares issuable upon
exercise of the Warrants ("Exercise Rate") is subject to adjustment upon the
occurrence of certain events set forth in the Warrant Agreement.

                  Any Warrants not exercised on or prior to 5:00 p.m., New York
City time, on February 1, 2007 shall thereafter be void.

                  If the Company merges, amalgamates or consolidates with or
into, or sells all or substantially all of its property and assets to, another
Person solely for cash, the holders of Warrants shall be entitled to receive
distributions on the date of such event on an equal basis with holders of Shares
(or other securities issuable upon exercise of the Warrants) as if the Warrants
had been exercised immediately prior to such event (less the Exercise Price).

                  Reference is hereby made to the further provisions on the
reverse hereof which provisions shall for all purposes have the same effect as
though fully set forth at this place.

                  This Warrant Certificate shall not be valid unless

THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS

                        AAVID THERMAL TECHNOLOGIES, INC.

                  The Warrants evidenced by this Warrant Certificate are part of
a duly authorized issue of Warrants expiring at 5:00 p.m., New York City time,
on [ ], 2007 (the "Expiration Date"), each of which represents the right to
purchase at any time on or after the Exercisability Date (as defined in the
Warrant Agreement) and on or prior to the Expiration Date [ ] shares of Class A
Common Stock and [ ] shares of Class H Common Stock, in each case subject to
adjustment as set forth in the Warrant Agreement. The Warrants are issued
pursuant to a Warrant Agreement dated as of February [ ], 2000 (the "Warrant
Agreement"), duly executed and delivered by the Company to Bankers Trust
Company, as Warrant Agent (the "Warrant Agent"), which Warrant Agreement is
hereby incorporated by reference in and made a part of this instrument and is
hereby referred to for a description of the rights, limitation of rights,
obligations, duties and immunities thereunder of the Warrant Agent, the Company
and the holders (the words "holders" or holder" meaning the registered holders
or registered holder) of the Warrants.

                  Warrants may be exercised by (i) surrendering at any Warrant
Agent Office this Warrant Certificate with the form of Election to Exercise set
forth hereon duly completed and executed and (ii) to the extent such exercise is
not being effected through a Cashless Exercise by paying in full the Warrant
Exercise Price for each such Warrant exercised and any other amounts required to
be paid pursuant to the Warrant Agreement.

                  If all of the items referred to in the preceding paragraph are
received by the Warrant Agent at or prior to 11:00 a.m., New York City time, on
a Business Day, the exercise of the Warrant to which such items relate will be
effective on such Business Day. If any items referred to in the preceding
paragraph are received after 11:00 a.m., New York City time, on a Business Day,
the exercise of the Warrants to which such item relates will be deemed to be
effective on the next succeeding Business Day. Notwithstanding the foregoing, in
the case of an exercise of Warrants on February 1, 2007, if all of the items
referred to in the preceding paragraph are received by the Warrant Agent at or
prior to 5:00 p.m., New York City time, on such Expiration Date, the exercise of
the Warrants to which such items relate will be effective on the Expiration
Date.

                  As soon as practicable after the exercise of any Warrant or
Warrants, the Company shall issue or cause to be issued to or upon the written
order of the registered holder of this Warrant Certificate, a certificate or
certificates evidencing the Share or Shares to which such holder is entitled, in
fully registered form, registered in such name or names as may be directed by
such holder pursuant to the Election to Exercise, as set forth on the reverse of
this Warrant Certificate. Such certificate or certificates evidencing the Share
or Shares shall be deemed to have been issued and any persons who are designated
to be named therein shall be

                                      A-8

<PAGE>

deemed to have become the holder of record of such Share or Shares as of the
close of business on the date upon which the exercise of this Warrant was deemed
to be effective as provided in the preceding paragraph.

                  The Company will not be required to issue fractional shares of
Common Stock upon exercise of the Warrants or distribute Share certificates that
evidence fractional shares of Common Stock. In lieu of fractional shares of
Common Stock, the Company may pay to the registered Holder of this Warrant
Certificate at the time such Warrant Certificate is exercised an amount in cash
equal to the same fraction of the Current Market Value per share of Common Stock
on the Business Day preceding the date this Warrant Certificate is surrendered
for exercise.

                  Warrant Certificates, when surrendered at any office or agency
maintained by the Company for that purpose by the registered holder thereof in
person or by legal representative or attorney duly authorized in writing, may be
exchanged for a new Warrant Certificate or new Warrant Certificates evidencing
in the aggregate a like number of Warrants, in the manner and subject to the
limitations provided in the Warrant Agreement, without charge except for any tax
or other governmental charge imposed in connection therewith.

                  Upon due presentment for registration of transfer of this
Warrant Certificate at any office or agency maintained by the Company for that
purpose, a new Warrant Certificate evidencing in the aggregate a like number of
Warrants shall be issued to the transferee in exchange for this Warrant
Certificate, subject to the limitations provided in the Warrant Agreement,
without charge except for any tax or other governmental charge imposed in
connection therewith.

                  The Company and the Warrant Agent may deem and treat the
registered holder hereof as the absolute owner of this Warrant Certificate
(notwithstanding any notation of ownership or other writing hereon made by
anyone) for the purpose of any exercise hereof and for all other purposes, and
neither the Company nor the Warrant Agent shall be affected by any notice to the
contrary.

                  The term "Business Day" shall mean any day on which (i) banks
in New York City, (ii) the principal U.S. securities exchange or market, if any,
on which the Common Stock is listed or admitted to trading and (iii) the
principal U.S. securities exchange or market, if any, on which the Warrants are
listed or admitted to trading are open for business.

                  The Warrants and the Shares are entitled to the benefits of a
registration rights agreement relating to the Warrants and the shares of Common
Stock issuable upon exercise thereof (the "Common Stock Registration Rights
Agreement"). The Common Stock Registration Rights Agreement provides the holders
of Registrable Securities with the right, subject to the conditions and
limitations contained therein, to include the Registrable Securities in certain
registration statements filed by the Company for its account or for the account
of any of its securityholders.

Significant Disposition) in such manner if and only if (i) concurrent with such
notice, such deferred proceeds are applied to repay the Revolving Credit Loans,
and (ii) within 270 days after receipt by the Administrative Agent of such
deferred proceeds, the Borrower, subject to SECTION 2.5 and SECTION 2.9 (a),
(b), (d), and (e), shall obtain Revolving Credit Loans for purposes of acquiring
replacement assets which are, in the ordinary course, used and useful in the
operation of the Thermal Management Solutions Business of the Borrower and its
Approved Subsidiaries ("Replacement Assets") (it being understood that upon
expiration of such 270-day period, any portion of such deferred proceeds that
has not been utilized by the Borrower as a Revolving Credit Loan to acquire such
Replacement Assets shall be applied in accordance with the next succeeding
sentence). Any Net Disposition Proceeds shall be applied PRO RATA to scheduled
installments of principal of the Term Loans. Notwithstanding the foregoing, the
Borrower shall deliver to the Administrative Agent 100% of the Net Disposition
Proceeds from a Significant Disposition within three Business Days after receipt
thereof and such proceeds shall be applied FIRST, PRO RATA to the scheduled
installments of principal of the Term Loans and SECOND, if the Term Loans have
been repaid in full, to the Revolving Credit Loans (with a concomitant reduction
in the Revolving Credit Commitments).



<PAGE>

(d)      For so long as any Term Loan is outstanding, the Borrower shall deliver
to the Administrative Agent within three Business Days after receipt thereof
100% of any Net Insurance Proceeds which, in the aggregate during the term of
this Agreement, exceeds $25,000,000, for application in the manner set forth in
the next sentence; PROVIDED that the Borrower, by written notice to the
Administrative Agent delivered within such three Business Day period (together
with a certificate in reasonable detail setting forth the calculation of Net
Insurance Proceeds), may elect to defer applying Net Insurance Proceeds
aggregating less than $25,000,000 in such manner if and only if (i) concurrent
with such notice such deferred proceeds are applied to repay the Revolving
Credit Loans, and (ii) within 270 days after receipt by the Administrative Agent
of such deferred proceeds, the Borrower, subject to SECTION 2.5 and SECTION 2.9
(a), (b), (c), and (e), shall obtain Revolving Credit Loans for purposes of
acquiring Replacement Assets (it being understood that upon expiration of such
270-day period, any portion of such deferred proceeds that has not been utilized
by the Borrower as a Revolving Credit Loan to acquire such Replacement Assets
shall be applied in accordance with the next succeeding sentence). Any Net
Insurance Proceeds shall be applied PRO RATA to the scheduled installments of
principal of the Term Loans.

(e)      The Borrower shall, concurrently with the receipt by the Parent, the
Borrower or any Subsidiary of any Net Debt Proceeds, pay to the Administrative
Agent an amount equal to such Net Debt Proceeds, which shall be applied PRO RATA
to scheduled installments of principal of the Term Loans.

(f)      If the Total Leverage Ratio of the Borrower and its Subsidiaries on
December 31, 2000 (as set forth in the Compliance Certificate for the fiscal
year ended on such date) is greater than 4.50 to 1.00, or the Total Leverage
Ratio of the Borrower and its Subsidiaries on December 31, 2001 (as set forth in
the Compliance Certificate for the fiscal year ended on such date) is greater
than 4.25 to 1.00, the Parent shall, not later than May 15, 2001 (in respect of
the fiscal year ended December 31, 2000) and/or May 15, 2002 (in respect of the
fiscal year ended December 31, 2001) make the Supplemental Equity Contribution
to the Borrower. The Borrower shall deliver 100% of the proceeds of such
Supplemental Equity Contribution to the Administrative Agent and such proceeds
shall be applied PRO RATA to the scheduled installments of principal of the Term
Loans.

(g)      If, at any time, the sum of (x) the outstanding aggregate principal
amount of the Revolving Credit Loans, (y) the aggregate Stated Amount of all
Letters of Credit then outstanding and (z) any amounts drawn under any Letter of
Credit (including interest thereon computed in accordance with SECTION 2.21(d))
for which the Issuer has not been reimbursed exceeds the then aggregate amount
of the Revolving Credit Commitments, then the Borrower shall prepay at such time
an aggregate principal amount of the Revolving Credit Loans in an aggregate
amount equal to such excess, and to the extent of any excess remaining, deliver
cash collateral for the Stated Amount of the Letter of Credit outstanding and
any amount drawn under the Letter of Credit for which the Issuer has not been
reimbursed.



<PAGE>

(h)      Each prepayment of Term Loans and Revolving Credit Loans pursuant to
this SECTION 2.9 shall be accompanied by payment in full of any outstanding fees
and expenses then due and owing and, in the case of any prepayment of Eurodollar
Loans, by payment in full of all accrued interest thereon, to and including the
date of such prepayment and any additional amounts owing pursuant to SECTION
2.19.

2.10     CONVERSION AND CONTINUATION OPTIONS . (a) The Borrower, upon
irrevocable written notice to the Administrative Agent in accordance with this
SECTION 2.10 (i) may elect, as of any Business Day, in the case of its Alternate
Base Rate Loans, or as of the last day of the applicable Interest Period, in the
case of any other Type of Loans of the Borrower, to convert any such Loans (or
any part thereof in an amount not less than $1,000,000, or that is an integral
multiple of $100,000 in excess thereof) into Loans of any other Type; or (ii)
may elect, as of the last day of the applicable Interest Period, to continue any
such Loans having Interest Periods expiring on such day (or any part thereof in
an amount not less than $1,000,000, or that is in an integral multiple of
$100,000 in excess thereof.

         (b) The Borrower shall deliver a written notice, substantially in the
form of EXHIBIT D (a "NOTICE OF CONVERSION/CONTINUATION") to be received by the
Administrative Agent not later than 11:00 a.m. (New York City time) (i) at least
three Business Days in advance of the Conversion/ Continuation Date, if the
Loans are to be converted from or into or continued as Eurodollar Rate Loans;
and (ii) on the Conversion/Continuation Date, if the Loans are to be converted
into Alternate Base Rate Loans.

         (c) If, upon the expiration of any Interest Period applicable to
Eurodollar Rate Loans made to the Borrower, the Borrower has failed to select
timely a new Interest Period to be applicable to such Loans, or if any Default
or Event of Default then exists, the Borrower shall be deemed to have elected to
convert such Eurodollar Rate Loans into Alternate Base Rate Loans effective as
of the expiration date of such Interest Period.

         (d) Upon receipt of any Notice of Conversion/Continuation, the
Administrative Agent shall promptly notify each Lender thereof. All or any part
of the outstanding Eurodollar Loans and Alternate Base Rate Loans may be
converted or continued as provided herein; PROVIDED that (i) no Loan may be
converted into, or continued as, a Eurodollar Loan when any Default has occurred
and is continuing and (ii) no Loan may be converted into, or continued as, a
Eurodollar Loan after the date that is one month prior to the Maturity Date.

2.11     MAXIMUM AMOUNTS OF TRANCHES . All borrowings, conversions and
continuations of Eurodollar Loans hereunder and all selections of Interest
Periods hereunder shall be in such amounts and shall be made pursuant to such
elections so that, after giving effect thereto, the aggregate principal amount
of the Eurodollar Loans comprising each Tranche shall be equal to $500,000 or a
whole multiple of $100,000 in excess thereof. There shall never be more than six
Tranches at any one time outstanding.



<PAGE>

2.12     INTEREST RATES AND PAYMENT DATES . (a) Each Eurodollar Loan shall
bear interest for each day during each Interest Period with respect thereto
at a rate per annum equal to the Eurodollar Rate determined for the first day
of such Interest Period (subject to daily adjustments, if any, required by
changes in the Eurocurrency Reserve Requirements) PLUS the Applicable Margin.

(b)      Each Alternate Base Rate Loan shall bear interest at a rate per annum
equal to the Alternate Base Rate PLUS the Applicable Margin.

(c)      In the event an Event of Default under SECTION 7.1(a) or (e) has
occurred and is continuing, the Loans shall bear interest at a rate per annum
equal to the rate that would otherwise be applicable thereto pursuant to the
foregoing provisions of this Section plus 2% from the date of occurrence of
such Event of Default until the date such Event of Default is cured or waived
(after as well as before judgment). In addition, should any interest on such
Loans or any commitment fee or other amount (other than principal) payable
hereunder not be paid when due (whether at the stated maturity, by
acceleration or otherwise), such overdue amount shall bear interest (to the
extent permitted by law in the case of interest on interest) at a rate per
annum which is the rate described in SECTION 2.12(b) plus 2%, in each case,
from the date of such non-payment until such amount is paid in full (after as
well as before judgment).

(d)      Interest shall be payable in arrears on each Interest Payment Date;
PROVIDED that interest accruing pursuant to SECTION 2.12(c) shall be payable
from time to time on demand.

2.13     COMPUTATION OF INTEREST AND FEES. (a) Commitment fees and Alternate
Base Rate interest shall be calculated on the basis of a 365/366 day year and
Eurodollar Rate interest shall be calculated on the basis of a 360-day year
for the actual days elapsed. The Administrative Agent shall as soon as
practicable notify the Borrower and the Lenders of each determination of a
Eurodollar Rate. Any change in the interest rate on a Loan resulting from a
change in the Alternate Base Rate or the Eurocurrency Reserve Requirements
shall become effective as of the opening of business on the day on which such
change becomes effective. The Administrative Agent shall as soon as
practicable notify the Borrower and the Lenders of the effective date and the
amount of each such change in interest rate.

(b)      Each determination of an interest rate by the Administrative Agent
pursuant to any provision of this Agreement shall be conclusive and binding on
the Borrower and the Lenders in the absence of manifest error. The
Administrative Agent, at the request of the Borrower, shall deliver to the
Borrower a statement showing the quotations used by the Administrative Agent in
determining any interest rate pursuant to SECTION 2.12(a).

(c)      All payments to be made by the Borrower shall be made without setoff,
recoupment or counterclaim. Except as otherwise expressly provided herein, all
payments by the Borrower shall be made to the Administrative Agent for the
account of the Lenders at the Administrative Agent's office specified in SECTION
10.2 and shall be made in Dollars. Such


<PAGE>

payments shall be made in like funds received, and no later than 12:00 p.m. (New
York City time) on the date specified herein. The Administrative Agent will
promptly distribute to each Lender its pro rata share (or other applicable share
as expressly provided herein) of such principal, interest, fees or other
amounts, in like funds as received for the account of the Lenders' respective
Applicable Lending Office. Any payment which is received by the Administrative
Agent later than 12:00 p.m. (New York City time) shall be deemed to have been
received on the following Business Day and any applicable interest or fee shall
continue to accrue.

2.14     INABILITY TO DETERMINE INTEREST RATE . If the Administrative Agent
shall have determined (which determination shall be conclusive and binding upon
the Borrower) that, by reason of circumstances affecting the relevant market,
adequate and reasonable means do not exist for ascertaining the Eurodollar Rate
for any requested Interest Period, or that the Eurodollar Rate determined or to
be determined for such Interest Period will not adequately and fairly reflect
the cost to the Lenders of making or maintaining their affected Loans, the
Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the Lenders as soon as practicable thereafter. If such notice is
given, (x) any Eurodollar Loans requested to be made on the first day of such
Interest Period shall be made as Alternate Base Rate Loans, (y) any Loans that
were to have been converted on the first day of such Interest Period to
Eurodollar Loans shall be continued as Alternate Base Rate Loans and (z) any
outstanding Eurodollar Loans shall be converted, on the first day of such
Interest Period, to Alternate Base Rate Loans. Until such notice has been
withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made
or continued as such, nor shall the Borrower have the right to convert Alternate
Base Rate Loans to Eurodollar Loans.

2.15      PRO RATA TREATMENT AND PAYMENTS; FUNDING RELIANCE . (a) Each
Borrowing by the Borrower from the Lenders hereunder, each payment by the
Borrower on account of any commitment fee hereunder and any reduction of the
Revolving Credit Commitments or the Term Loan Commitments of the Lenders
shall be made PRO RATA according to the respective Revolving Credit
Commitments or Term Loan Commitments of the Lenders. Each payment (including
each prepayment) by the Borrower on account of principal of and interest on
the Loans or any Letter of Credit (except as may be required as a result of
SECTION 2.16) shall be made pro rata according to the respective Revolving
Credit Commitment Percentages or Term Loan Commitment Percentages, as
applicable. All payments (including prepayments) to be made by the Borrower
hereunder and under the Revolving Credit Notes or the Term Notes, whether on
account of principal, interest, fees or otherwise, or on account of any
Letter of Credit, shall be made without setoff or counterclaim and shall be
made prior to 12:00 p.m., New York City time, on the due date thereof to the
Administrative Agent, for the account of the Lenders, at the Administrative
Agent's office specified in SECTION 10.2 and in immediately available funds.
The Administrative Agent shall distribute such payments to the Lenders for
the account of their respective Applicable Lending Offices promptly upon
receipt in like funds as received. If any payment hereunder (other than
payments on the Eurodollar Loans) becomes due and payable on a day other than
a Business Day, such payment shall be extended to the next succeeding
Business Day, and, with respect to payments of principal and interest
thereon, shall be payable at the then applicable rate

<PAGE>

during such extension. If any payment on a Eurodollar Loan becomes due and
payable on a day other than a Business Day, the maturity thereof shall be
extended to the next succeeding Business Day (and, with respect to payments of
principal and interest thereon, shall be payable at the then applicable rate
during such extension) unless the result of such extension would be to extend
such payment into another calendar month, in which event such payment shall be
made on the immediately preceding Business Day.

(b)      Unless the Administrative Agent shall have been notified in writing by
any Lender prior to a Borrowing that such Lender will not make available to the
Administrative Agent the amount that would constitute its applicable Commitment
Percentage of such Borrowing, the Administrative Agent may assume that such
Lender is making such amount available to the Administrative Agent, and the
Administrative Agent may, in reliance upon such assumption, make available to
the Borrower a corresponding amount. If such amount is not made available to the
Administrative Agent by the required time on the Borrowing Date therefor, such
Lender shall pay to the Administrative Agent, on demand, such amount with
interest thereon at a rate equal to the daily average Federal Funds Rate for the
period until such Lender makes such amount immediately available to the
Administrative Agent. A certificate of the Administrative Agent submitted to any
Lender with respect to any amounts owing under this Section shall be conclusive
in the absence of manifest error. If such Lender's applicable Commitment
Percentage of such Borrowing is not made available to the Administrative Agent
by such Lender within three Business Days of such Borrowing Date, the
Administrative Agent shall also be entitled to recover such amount with interest
thereon at the rate per annum applicable to Alternate Base Rate Loans hereunder,
on demand, from the Borrower.

2.16     ILLEGALITY . Notwithstanding any other provision herein, if the
adoption of or any change in any Requirement of Law or in the interpretation or
application thereof shall make it unlawful for any Lender to make or maintain
Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such
Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert Alternate Base Rate Loans to Eurodollar Loans shall forthwith be
canceled and (b) such Lender's Loans then outstanding as Eurodollar Loans, if
any, shall be converted automatically to Alternate Base Rate Loans on the
respective last days of the then current Interest Periods with respect to such
Loans or within such earlier period as required by law. If any such conversion
of a Eurodollar Loan occurs on a day which is not the last day of the then
current Interest Period with respect thereto, the Borrower shall pay to such
Lender such amounts, if any, as may be required pursuant to SECTION 2.19.

2.17      REQUIREMENTS OF LAW. (a) If the adoption of or any change in any
Requirement of Law or in the interpretation or application thereof or compliance
by any Lender with any request or directive (whether or not having the force of
law) from any central bank or other Governmental Authority made subsequent to
the date hereof:


         (i)      shall subject any Lender to any tax of any kind whatsoever
         with respect to this Agreement, or any Note or any Loan made by it, or
         change the basis of


<PAGE>

         taxation of payments to such Lender in respect thereof (except for
         Non-Excluded Taxes covered by SECTION 2.18 and changes in the rate of
         tax on the overall net income of such Lender);

         (ii)     shall impose, modify or hold applicable any reserve, special
         deposit, compulsory loan or similar requirement against assets held by,
         deposits or other liabilities in or for the account of, advances, loans
         or other extensions of credit by, or any other acquisition of funds by,
         any office of such Lender which is not otherwise included in the
         determination of the Eurodollar Rate hereunder; or

         (iii)    shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Loans or to reduce any amount receivable hereunder in
respect thereof, then, in any such case, the Borrower shall promptly pay such
Lender, upon its demand, any additional amounts necessary to compensate such
Lender for such increased cost or reduced amount receivable. If any Lender
becomes entitled to claim any additional amounts pursuant to this Section, it
shall promptly notify the Borrower, through the Administrative Agent, of the
event by reason of which it has become so entitled. A certificate as to any
additional amounts payable pursuant to this Section submitted by such Lender,
through the Administrative Agent, to the Borrower shall be conclusive in the
absence of manifest error. This covenant shall survive the termination of this
Agreement and the payment of the Obligations hereunder.

(b)      If any Lender shall have determined that the adoption of or any change
in any Requirement of Law regarding capital adequacy or in the interpretation or
application thereof or compliance by such Lender or any corporation controlling
such Lender with any request or directive regarding capital adequacy (whether or
not having the force of law) from any Governmental Authority made subsequent to
the date hereof has or shall have the effect of reducing the rate of return on
such Lender's or such corporation's capital as a consequence of its obligations
hereunder to a level below that which such Lender or such corporation could have
achieved but for such change or compliance (taking into consideration such
Lender's or such corporation's policies with respect to capital adequacy) by an
amount deemed by such Lender to be material, then from time to time, after
submission by such Lender to the Borrower (with a copy to the Administrative
Agent) of a written request therefor, the Borrower shall pay to such Lender such
additional amount or amounts as will compensate such Lender for such reduction.
This covenant shall survive the termination of this Agreement and the payment of
the Obligations hereunder.

2.18      TAXES . (a) All payments made by the Borrower under this Agreement and
the Notes shall be made free and clear of, and without deduction or
withholding for or on account of, any present or future income, stamp or
other taxes, levies, imposts, duties, charges, fees, deductions or
withholdings, now or hereafter imposed, levied, collected, withheld or
assessed by


<PAGE>

any Governmental Authority, excluding net income taxes and franchise taxes
(imposed in lieu of net income taxes) imposed on the Administrative Agent or any
Lender as a result of a present or former connection between the Administrative
Agent or such Lender and the jurisdiction of the Governmental Authority imposing
such tax or any political subdivision or taxing authority thereof or therein
(other than any such connection arising solely from the Administrative Agent or
such Lender having executed, delivered or performed its obligations or received
a payment under, or enforced, this Agreement or the Notes). If any such
non-excluded taxes, levies, imposts, duties, charges, fees, deductions or
withholdings ("NON-EXCLUDED TAXES") are required to be withheld from any amounts
payable to the Administrative Agent or any Lender hereunder or under the Notes,
the amounts so payable to the Administrative Agent or such Lender shall be
increased to the extent necessary to yield to the Administrative Agent or such
Lender (after payment of all Non-Excluded Taxes) interest or any such other
amounts payable hereunder at the rates or in the amounts specified in this
Agreement and the Notes; PROVIDED that the Borrower shall not be required to
increase any such amounts payable to any Lender that is not organized under the
laws of the United States of America or a state thereof if such Lender fails to
comply with the requirements of paragraph (b) of this Section. Whenever any
Non-Excluded Taxes are payable by the Borrower, as promptly as possible
thereafter, the Borrower shall send to the Administrative Agent for its own
account or for the account of such Lender, as the case may be, a certified copy
of an original official receipt received by the Borrower showing payment
thereof. If the Borrower fails to pay any Non-Excluded Taxes when due to the
appropriate taxing authority or fails to remit to the Administrative Agent the
required receipts or other required documentary evidence, the Borrower shall
indemnify the Administrative Agent and the Lenders for any incremental taxes,
interest or penalties that may become payable by the Administrative Agent or any
Lender as a result of any such failure. The covenants in this Section shall
survive the termination of this Agreement and the payment of the Notes and
payment of the Obligations hereunder.


<PAGE>

(b)      Each Lender shall:

         (i)      deliver to the Borrower and the Administrative Agent (A) in
         the case of a Lender that is not organized under the laws of the United
         States or any State thereof, either (x)one duly completed copy of
         United States Internal Revenue Service Form W-8BEN or W-8ECI, or
         successor applicable form, as the case may be, if such Lender intends
         to claim exemption from withholding of U.S. Federal income tax on the
         basis that such Lender is eligible for the benefits of an income tax
         treaty or that such Lender's income received hereunder is effectively
         connected with its conduct of a U.S. trade or business, or (y) if such
         Lender is not a "bank" within the meaning of Section 881(c)(3)(A) of
         the Code and intends to claim exemption from withholding of U.S.
         Federal income tax under Section 871(h) or Section 881(c) of the Code
         with respect to payments of "portfolio interest", a Form W-8BEN, or any
         successor applicable form, together with a certificate executed by such
         Lender representing that (1) such Lender is not a bank for purposes of
         Section 881(c) of the Code, is not a 10 percent shareholder (within the
         meaning of Section 871(h)(3)(B) of the Code) of the Borrower and is not
         a controlled foreign corporation related to the Borrower (within the
         meaning of Section 864(d)(4) of the Code), claiming complete exemption
         from withholding of U.S. Federal income tax on payments of interest by
         the Borrower under this Agreement and the other Loan Documents and (2)
         that the Lender has received in replacement of any Note held by or
         assigned to it, a QFL Note in accordance with this SECTION 2.18, and
         (B) in the case of any other Lender, an Internal Revenue Service Form
         W-9, or successor applicable form;

         (ii)     deliver to the Borrower and the Administrative Agent a further
         copy of any such form or certification on or before the date that any
         such form or certification expires or becomes obsolete and after the
         occurrence of any event requiring a change in the most recent form
         previously delivered by it to the Borrower; and

         (iii)    obtain such extensions of time for filing and complete such
         forms or certifications as may reasonably be requested by the Borrower
         or the Administrative Agent;

unless in any such case an event (including, without limitation, any change in
treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Lender from duly completing and delivering any such
form with respect to it and such Lender so advises the Borrower and the
Administrative Agent. Such Lender shall certify (i) in the case of a Form W-8BEN
or W-8ECI, that it is entitled to receive payments under this Agreement without
deduction or withholding of any United States federal income taxes and (ii) in
the case of a Form W-9, that it is entitled to an exemption from United States
backup withholding tax. Each Person that shall become a Lender or a Participant
pursuant to SECTION 10.6 shall, upon the effectiveness of the related transfer,
be required to provide all the forms and statements required pursuant to this


<PAGE>

Section; PROVIDED that, in the case of a Participant, such Participant shall
furnish all such required forms and statements to the Lender from which the
related participation shall have been purchased.

(c)      Any Lender that is not a "bank" within the meaning of Section
881(c)(3)(A) of the Code and satisfies the requirements of SECTION
2.18(b)(i)(A)(y), (a "QUALIFIED FOREIGN LENDER") shall upon receipt of the
written request of the Administrative Agent or the Borrower and may, upon its
own written request to the Administrative Agent, exchange any Note held by or
assigned to it for a qualified foreign lender Note ( a "QFL NOTE"). A QFL Note
shall be in the form of the Revolving Credit Note or Term Note, as applicable,
but shall contain the following legend, "This Note is a QFL Note, and as such,
ownership of the obligation represented by such QFL Note may be transferred only
in accordance with Section 2.18 of the Credit Agreement." Any QFL Note issued in
replacement of any existing Note pursuant to this Section shall be (i) dated the
Effective Date, (ii) issued in the name of the entity in whose name such
existing Note was issued and (iii) issued in the same principal amount as such
existing Note. Any Note replaced pursuant to this Section is sometimes referred
to herein as a "REPLACED NOTE".

(d)      The Borrower agrees that, upon the request of or delivery of a request
to a Qualified Foreign Lender pursuant to paragraph (c) of this Section, it
shall execute and deliver a QFL Note to the Administrative Agent in replacement
of the Replaced Note surrendered in connection with such request conforming to
the requirements of this paragraph. Each Qualified Foreign Lender shall
surrender its Note in connection with any replacement pursuant to this SECTION
2.18. Upon receipt by the Administrative Agent, in connection with any
replacement, of a QFL Note and the existing Note to be replaced by such QFL Note
in accordance with this paragraph, the Administrative Agent shall forward the
QFL Note to the Lender which has surrendered its Note for replacement by such
QFL Note and shall forward the surrendered Note to the Borrower marked
"canceled". Once issued, QFL Notes (i) shall be deemed to and shall be "Notes"
for all purposes under the Loan Documents, (ii) may not be exchanged for Notes
which are not QFL Notes, notwithstanding anything to the contrary in the Loan
Documents and (iii) shall at all times thereafter be QFL Notes, including,
without limitation, following any transfer or assignment thereof.

(e)      Notwithstanding anything to the contrary in the Loan Documents, the QFL
Notes are registered obligations as to both principal and interest with the
Borrower and transfer of the obligations underlying such QFL Note may be
effected only by surrender of the QFL Note to the Borrower and either reissuance
by the Borrower of such QFL Note to the transferee or issuance by the Borrower
of a new QFL Note to the transferee. A QFL Note shall only evidence the Lender's
or an assignee's right, title and interest in and to the related obligation, and
in no event is a QFL Note to be considered a bearer instrument or obligation.
This SECTION 2.18 shall be construed so that the obligations underlying the QFL
Notes are at all times maintained in "registered form" within the meaning of
Sections 871(h)(2) and 881(c)(3) of the Code.


<PAGE>

2.19     INDEMNITY . The Borrower agrees to indemnify each Lender and to hold
each Lender harmless from any loss or expense which such Lender may sustain or
incur as a consequence of (a) default by the Borrower in payment when due of the
principal amount of or interest on any Eurodollar Loan, (b) default by the
Borrower in making a borrowing of, conversion into or continuation of Eurodollar
Loans after the Borrower has given a notice requesting the same, (c) default by
the Borrower in making any prepayment after the Borrower has given a notice
thereof or (d) the making of a prepayment or conversion of Eurodollar Loans on a
day which is not the last day of an Interest Period with respect thereto
including, without limitation, in each case, any such loss or expense arising
from the redeployment of funds obtained by it or from fees payable to terminate
the deposits from which such funds were obtained. This covenant shall survive
the termination of this Agreement and the payment of the Obligations hereunder.

2.20     DISCRETION OF LENDER AS TO MANNER OF FUNDING . Notwithstanding any
other provisions of this Agreement, each Lender shall be entitled to fund and
maintain its funding of all or any part of its Loans in any manner it sees fit,
it being understood that for the purposes of this Agreement all determinations
hereunder shall be made assuming each Lender had actually funded and maintained
each Eurodollar Loan through the purchase of deposits of Dollars for such Loan
in the eurocurrency interbank market having a maturity corresponding to each
Loan's Interest Period and bearing an interest rate equal to the Eurodollar Rate
for such Interest Period.

2.21     LETTERS OF CREDIT . (a) Subject to the terms and conditions hereof,
and in reliance on the agreements set forth in clauses (c) and (e) hereof,
from time to time, on any Business Day, the Issuer agrees to issue Letters of
Credit for the account of the Borrower in such form as may be approved from
time to time by the Issuer; PROVIDED that (i) the sum of the aggregate face
amount of all Letters of Credit outstanding and the aggregate amount drawn
under all Letters of Credit for which the Issuer has not been reimbursed at
any time shall not exceed $2,000,000 and (ii) the sum of the Revolving Credit
Loans, the aggregate face amount of all Letters of Credit outstanding and the
aggregate amount drawn under all Letters of Credit for which the Issuer has
not been reimbursed shall not, at any time, exceed the Revolving Credit
Commitment (as reduced from time to time pursuant to SECTION 2.5 and SECTION
2.9).

(b)      Each Letter of Credit (i) shall be opened pursuant to a written request
from the Borrower on the Issuer's then current form of application for letter of
credit which application shall be completed to the satisfaction of the Issuer
and shall be delivered to the Issuer together with such other certificates,
documents and other instruments and information as the Issuer may reasonably
request, (ii) shall be denominated in Dollars, (iii) shall be governed by the
Uniform Customs and, to the extent not inconsistent therewith, the laws of the
State of New York and (iv) shall expire on the Expiry Date. The Issuer shall not
at any time be obligated to issue any Letter of Credit if such issuance would
conflict with, or cause the Issuer or any Revolving Credit Lender to exceed any
limits imposed by, an applicable Requirement of Laws.


<PAGE>

(c)      The Issuer agrees to allot and does allot, to itself and each Revolving
Credit Lender and, to induce the Issuer to issue the Letter of Credit, each
Revolving Credit Lender severally and irrevocably agrees to take and does hereby
take for its own account and risk an undivided participating interest in a
percentage equal to such Revolving Credit Lender's Revolving Credit Commitment
Percentage of the Issuer's Obligations.

(d)      The Borrower agrees (i) to reimburse the Issuer forthwith upon its
demand for any payment made by the Issuer under a Letter of Credit and (ii) to
pay interest on any unreimbursed portion of any such payment from the date of
such payment until reimbursement in full thereof at a rate per annum equal to
(A) prior to the date which is one Business Day after the day on which
reimbursement from the Borrower for such payment is due, the rate which would
then be payable on any outstanding Alternate Base Rate Loans which are not
overdue and (B) thereafter, the rate which would then be payable on any
outstanding Alternate Base Rate Loans which are overdue. In addition to the
foregoing, the Borrower shall reimburse the Issuer for any taxes, fees, charges
or other costs or expenses incurred by the Issuer in connection with such
payment. All payments hereunder shall be made to the Issuer at its address for
notices specified herein in Dollars in immediately available funds.

(e)      (i)    In the event that the Issuer makes a payment under a Letter of
Credit and is not reimbursed in full therefor forthwith, upon demand of the
Issuer referred to in SECTION 2.21(d), the Issuer shall promptly make demand
for such any amount for which it has not received reimbursement upon each
Revolving Credit Lender. Each Revolving Credit Lender unconditionally and
irrevocably agrees that forthwith upon its receipt of any such demand for
reimbursement, such Revolving Credit Lender shall transfer to the Issuer, in
immediately available funds, an amount equal to such Revolving Credit
Lender's PRO RATA share of the unreimbursed portion of such payment; PROVIDED
that, if such demand is made prior to 12:00 noon, New York City time, on a
Business Day, such Revolving Credit Lender shall make such payment to the
Issuer prior to the end of such Business Day and otherwise such Revolving
Credit Lender shall make such payment on the next succeeding Business Day.
Whenever, at any time after the Issuer has made a payment under a Letter of
Credit and has received from any Revolving Credit Lender such Revolving
Credit Lender's PRO RATA share of the unreimbursed portion of such payment,
the Issuer receives any reimbursement on account of such unreimbursed portion
or any payment of interest on account thereof, the Issuer shall distribute to
such Revolving Credit Lender its PRO RATA share thereof; PROVIDED that in the
event that the receipt by the Issuer of such reimbursement or such payment of
interest (as the case may be) is required to be returned, such Revolving
Credit Lender will return to the Issuer any portion thereof previously
distributed by the Issuer to such Revolving Credit Lender.

(ii)    Upon the occurrence and during the continuation of any Event of Default
under SECTION 7.1(e) or SECTION 7.1(f) or, with notice from the Administrative
Agent, upon the occurrence of any other Event of Default that is continuing (x)
an amount equal to the outstanding Letters of Credit shall, without demand upon
or notice to the Borrower, be deemed to have been paid or disbursed by the
Issuer upon such Letters of Credit (notwithstanding that such


<PAGE>

amount may not in fact have been paid or disbursed); and (y) without further
notice in the case of an Event of Default under SECTION 7.1(e) or SECTION 7.1(f)
or, in the case of any other Event of Default that has occurred and is
continuing, upon notice by the Administrative Agent to the Borrower of its
Obligations hereunder, the Borrower shall be immediately obligated to reimburse
the Issuer for the amount deemed to have been paid or disbursed by the Issuer.
Any amount so payable by the Borrower shall be deposited by the Borrower in cash
into an account located in the United States designated by and under the sole
dominion and control of the Administrative Agent which cash and the proceeds
thereof shall be held as collateral security for the Obligations in connection
with any Letter of Credit issued by the Issuer. The Borrower hereby grants to
the Administrative Agent, for the benefit of the Issuer and the Revolving Credit
Lenders, a security interest in such cash collateral to secure all Obligations
of the Borrower under this Agreement and the other Loan Documents. Amounts held
in such cash collateral account shall be applied by the Administrative Agent to
the payments of drafts drawn under any Letter of Credit, and the unused portion
thereof after all Letters of Credit shall have expired or been fully drawn upon,
if any, shall be applied to repay other Obligations. After all Letters of Credit
shall have expired or been fully drawn upon, all Reimbursement Obligations shall
have been fully satisfied and all other Obligations shall have been paid in
full, the balance, if any, in such cash collateral account shall be returned to
the Borrower. The Borrower shall execute and deliver to the Administrative
Agent, for the account of the Issuer, such further documents and instruments as
the Administrative Agent may request to evidence the creation and perfection of
the security interest in such cash collateral account.

(f)      The Borrower shall pay to the Administrative Agent for the pro rata
account of the Issuer and the Revolving Credit Lenders in respect of each Letter
of Credit a fee in an amount equal to the Applicable Margin then in effect for
Revolving Credit Loans that bear interest at the Eurodollar Rate (calculated on
the basis of the actual number of days elapsed over a 360-day year) multiplied
by the Stated Amount of the Letter of Credit, such fee to be payable for the
period from the date of issuance to the Expiry Date of such Letter of Credit,
quarterly in arrears on each Interest Payment Date for each quarter prior to
such Expiry Date.

(g)      The Borrower agrees to pay to the Issuer, for its own account, for
services rendered by the Issuer, an issuance fee for each Letter of Credit in
the amount equal to .25% of the Stated Amount of such Letter of Credit from the
date of issuance of such Letter of Credit, payable quarterly, in arrears. The
Borrower shall also pay or reimburse the Issuer for such normal and customary
costs and expenses as are incurred or charged by the Issuer on issuing,
effecting payment under, amending or otherwise administering any Letter of
Credit.

(h)      The Reimbursement Obligations of the Borrower with respect to the
Letter of Credit related thereto shall be unconditional and irrevocable and
shall be paid strictly in accordance with the terms of this Agreement under all
circumstances, including, without limitation, the following: (i) the existence
of any claim, set-off, defense or other right which the Borrower may have at any
time against any beneficiary, or any transferee, of such Letter of Credit (or
any Persons for whom any such beneficiary or any such transferee may be acting),
the


<PAGE>

Administrative Agent, the Issuer, any Lender or any other Person, whether in
connection with this Agreement or the transactions contemplated herein, or any
unrelated transaction; (ii) any statement or any other document presented under
such Letter of Credit proving to be forged, fraudulent, invalid or insufficient
in any respect or any statement therein being untrue or inaccurate in any
respect; (iii) payment by the Issuer under such Letter of Credit against
presentation of a draft or certificate which does not comply with the terms of
such Letter of Credit or any other circumstances or happening whatsoever,
whether or not similar to any of the foregoing (PROVIDED, that such payment by
the Issuer or such circumstance or happening does not constitute gross
negligence or willful misconduct of the Issuer).

(i)      To the extent that any provision of any application for the opening of
a Letter of Credit is inconsistent with the provisions of this SECTION 2.21, the
provisions in this Section shall apply.

2.22     DEFAULTING LENDERS . (a) Any Lender which (i) has refused (which
refusal has not been retracted) to make available its portion of any Borrowing
or to fund its portion of any unreimbursed payment under SECTION 2.21(e) or (ii)
has given notice to the Administrative Agent and/or the Borrower that it does
not intend to comply with its obligations under SECTIONS 2.1, 2.6 or 2.21(e), as
a result of the appointment of a receiver or conservator with respect to such
Lender at the direction or request of any regulatory agency or authority (and
such non-compliance is continuing) (a "DEFAULTING LENDER"):

                  (x) shall not be deemed a Required Lender hereunder and such
         Defaulting Lender's (A) Commitments, (B) Loans and (C) participation of
         Letters of Credit shall be excluded from the calculations set forth in
         the definition of Required Lenders; and

                  (y) shall not be entitled to receive any commitment fee
         payable in respect of such Defaulting Lender's Revolving Loan
         Commitment.

In addition to the foregoing, if any Lender shall fall within the description
set forth in CLAUSE (i) or (ii) above, the Issuer shall not be required to issue
any Letter of Credit, unless arrangements reasonably satisfactory to the Issuer
have been entered into to eliminate the Issuer's risk with respect to the
participation in Letters of Credit by such Lender, including providing cash
collateral for such Lender's portion of any outstanding Letters of Credit.

                  (b) The Borrower may designate another Person which is
reasonably acceptable to the Administrative Agent (a "REPLACEMENT LENDER") to
purchase for cash all the Notes of such Defaulting Lender and all such
Defaulting Lender's rights hereunder, without recourse to or warranty (other
than title) by, or expense to, such Defaulting Lender for a purchase price equal
to the outstanding principal amount of the Notes payable to such Defaulting
Lender plus any accrued but unpaid interest on such Notes and accrued but unpaid
commitment and other fees, expense reimbursements and indemnities in respect of
such Defaulting Lender's Commitments. Such Defaulting Lender shall consummate
such sale in accordance with such


<PAGE>

terms (and, if such Lender is an Issuer, such other terms as may be necessary to
compensate fully such Lender) within a reasonable time not exceeding 45 days
from the date the Borrower designates a Replacement Lender, and thereupon such
Defaulting Lender shall no longer be a party hereto or have any obligations or
rights hereunder (except rights which, pursuant to the provisions of this
Agreement, survive the termination of this Agreement and the repayment of the
Notes), and the Replacement Lender shall succeed to such obligations and rights.

                   ARTICLE 3. REPRESENTATIONS AND WARRANTIES

                  To induce the Administrative Agent, the Issuer and the Lenders
to enter into this Agreement, the Issuer to issue the Letter of Credit and the
Lenders to make the Loans, each of the Parent, Heat Holdings II and the Borrower
hereby represents and warrants to the Administrative Agent, the Issuer and each
Lender that:

3.1      FINANCIAL CONDITION . (a) The audited balance sheet of the Borrower
as at December 31, 1997 and 1998 and the related audited statements of
operations, stockholders equity and cash flows for the fiscal years ended on
such dates, certified as true and complete by a Responsible Officer of the
Borrower and reported on by Arthur Andersen LLP, copies of which have
heretofore been furnished to each Lender, are complete and correct in all
material respects and present fairly in all material respects the financial
condition of the Borrower as at such dates, and the results of its operations
and its stockholders' equity and cash flows for each of the fiscal years then
ended. The unaudited balance sheet of the Borrower as at October 2, 1999 and
the related unaudited statements of operations, stockholders' equity and cash
flows for the nine-month period ended on such date, certified by a
Responsible Officer of the Borrower, copies of which have heretofore been
furnished to each Lender, present fairly in all material respects the
financial condition of the Borrower at such date, and the results of its
operations, stockholders equity and cash flows for the nine-month period then
ended (subject to normal year end audit adjustments). All such financial
statements, including the related schedules and notes thereto, have been
prepared in accordance with U.S. GAAP applied consistently throughout the
periods involved (except as approved by such accountants or Responsible
Officer, as the case may be, and as disclosed therein and except that the
unaudited financial statements do not have all footnotes required).

(b)      Prior to the Effective Date and excluding any obligations of the Parent
pursuant to the Merger Agreement, the Parent did not have liabilities in excess
of $1,000,000 in the aggregate.

(c)      The PRO FORMA balance sheet of the Borrower and its Subsidiaries (the
"PRO FORMA BALANCE SHEET") is the balance sheet of the Borrower and its
Subsidiaries as at October 2, 1999, adjusted to give effect (as if such events
had occurred on the date the Merger is consummated) (i) to the Merger, (ii) to
the repayment of the Borrower's existing Indebtedness that is to be repaid on
the Effective Date, (iii) to the Loans expected to be made by the Lenders on the
Effective


<PAGE>

Date, (iv) to the Thermalloy Acquisition, (v) to the issuance of the Permitted
High Yield Securities and (vi) to the payment of fees and expenses in connection
with the foregoing. The Pro Forma Balance Sheet, together with the notes
thereto, presents fairly in all material respects on a PRO FORMA basis the
financial position of the Borrower and its Subsidiaries as at October 2, 1999
assuming that the events and the assumptions specified in the preceding sentence
had actually occurred on such date.

(d)      Except as set forth in SCHEDULE 3.1(d), none of the Parent, Merger Sub,
the Borrower or any of their respective Subsidiaries has, at the date of the Pro
Forma Balance Sheet referred to above, any material Guarantee Obligation,
contingent liability or liability for taxes, or any long-term lease or unusual
forward or long-term commitment, including, without limitation, any interest
rate or foreign currency swap or exchange transaction, which is not reflected in
the foregoing statements or in the notes thereto. Except as set forth in
SCHEDULE 3.1(d), during the period from December 31, 1998 to and including the
date hereof there has been no sale, transfer or other disposition by the Parent,
Merger Sub, the Borrower or any Subsidiary of any material part of its business
or property and no purchase or other acquisition of any business or property
(including any Capital Stock of any other Person) material in relation to the
financial condition of the Parent, Merger Sub, the Borrower or any Subsidiary at
such date other than the Merger and the Thermalloy Acquisition.

(e)      All balance sheets, all statements of operations and stockholders'
equity and of cash flows and all other financial information which shall
hereafter be furnished by or on behalf of the Parent, the Borrower or any of
their respective Subsidiaries to the Administrative Agent or any Lender for the
purposes of, or in connection with, this Agreement or any transaction
contemplated hereby have been or will be prepared in accordance with U.S. GAAP
consistently applied throughout the periods involved (except as disclosed
therein) and do or will present fairly in all material respects the financial
condition of the Parent, the Borrower and their respective Subsidiaries in each
case, as at the dates thereof and the results of their operations and their
stockholders' equity and cash flows for the periods then ended.

(f)      The business forecast of the Borrower and its Subsidiaries calculated
for the period commencing on the Effective Date to and including the Maturity
Date, prepared by a Responsible Officer of the Borrower (and presented on a
consolidated and segment by segment basis) all as set forth in SCHEDULE 3.1(f)
have been prepared in good faith and utilizing reasonable assumptions. Neither
the Parent nor the Borrower has any reason to believe such business forecast and
projections are materially incorrect or misleading in any material respect, it
being recognized by the Lenders that such business forecast as to future events
is not to be viewed as fact and that actual results during the periods covered
by such forecast may differ from the forecast results.

3.2      NO CHANGE . Since December 31, 1998, (a) there has been no development
or event which has had or could reasonably be expected to have a Material
Adverse Effect and (b) no dividends or other distributions have been declared,
paid or made upon the Capital Stock of the Parent, the Borrower or any
Subsidiary, nor has any of the Capital Stock


<PAGE>

of the Parent, Merger Sub, the Borrower or any Subsidiary been redeemed,
retired, purchased or otherwise acquired by the Parent, Merger Sub, the
Borrower, any Subsidiary or any Person under the control of the Parent, Merger
Sub, the Borrower or any Subsidiary for value, except for (i) the purchase of
the Capital Stock of the Borrower in accordance with the terms and conditions of
the Merger Documents, (ii) dividends and distributions contemplated or permitted
by the Thermalloy Acquisition Documents, (iii) dividends and distributions
reflected in the financial statements delivered pursuant to SECTION 3.1, (iv)
dividends and distributions by a Subsidiary to its stockholders, (v) the
purchase of Capital Stock of the Thermalloy Companies by Subsidiaries of the
Borrower and (vi) dividends and distributions paid pursuant to the Restructuring
and as described in SCHEDULE 1.2.

3.3      CORPORATE EXISTENCE; COMPLIANCE WITH LAW . Each of the Parent, Heat
Holdings II, the Borrower and each of their respective Subsidiaries (a) is duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization, (b) has the corporate or other power and
authority, and the legal right, to own and operate its property, to lease the
property it operates as lessee and to conduct the business in which it is
currently engaged, (c) is duly qualified as a foreign corporation or other legal
entity and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of property or the conduct of its business
requires such qualification, except where the failure to be so qualified could
not reasonably be expected to have a Material Adverse Effect and except for
jurisdictions not recognizing the concept of good standing and (d) is in
compliance with all Requirements of Law except to the extent that the failure to
comply therewith could not reasonably be expected to have a Material Adverse
Effect.

3.4      CORPORATE POWER; AUTHORIZATION; ENFORCEABLE OBLIGATIONS . Each of the
Parent, Heat Holdings II, the Borrower and each of their respective Subsidiaries
has the corporate or other power and authority, and the legal right, to make,
deliver and perform the Loan Documents to which it is a party and to authorize
the execution, delivery and performance of the Loan Documents to which it is a
party. The Borrower has appropriate power and authority to borrow hereunder and
has taken all necessary corporate action to authorize the borrowings on the
terms and conditions set forth in this Agreement and in the Notes. Except as set
forth in SCHEDULE 3.4, (a) no consent or authorization of, filing with, notice
to or other act by or in respect of, any Governmental Authority (including any
filing, termination of any notice period or consent under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended) is required in connection with
the Merger or any borrowings hereunder or with the execution, delivery or
performance by the Parent, the Borrower or any Subsidiary of, or the validity or
enforceability of the Merger Documents or the Loan Documents, other than any of
the foregoing which have previously been obtained and are in full force and
effect and (b) no consent or authorization of, filing with, notice to or other
act by or in respect of any other Person is required in connection with the
borrowings hereunder or with the execution, delivery, performance, validity or
enforceability of the Loan Documents or the Merger Documents to which the
Parent, the Borrower or any of their respective Subsidiaries is a party. This
Agreement has been, and each


<PAGE>

other Loan Document to which it is a party will be, duly executed and delivered
on behalf of the Parent, the Borrower and each Subsidiary party thereto. This
Agreement constitutes, and each other Loan Document to which the Parent, the
Borrower or any of their respective Subsidiaries, as the case may be, is a party
when executed and delivered will constitute, a legal, valid and binding
obligation of the Parent, the Borrower or such Subsidiary, as the case may be,
enforceable against the Parent, the Borrower or such Subsidiary, as the case may
be, in accordance with its terms, except as the enforceability may be limited by
bankruptcy, insolvency or other similar laws affecting the rights of creditors
generally and by general equitable principles (whether enforcement is sought by
proceedings in equity or at law).

3.5      NO LEGAL BAR . The execution, delivery and performance of the Loan
Documents to which the Parent, the Borrower or any of their respective
Subsidiaries is a party, the borrowings by the Borrower hereunder and the use of
the proceeds thereof will not violate any Requirement of Law applicable to the
Parent, the Borrower or any Subsidiary or Contractual Obligation of the Parent,
the Borrower or any Subsidiary, except such violations which, in the aggregate,
could not reasonably be expected to result in liability in excess of the Dollar
Equivalent of $500,000, will not accelerate or result in the acceleration of any
payment obligations of the Parent, the Borrower or any Subsidiary and will not
result in, or require, the creation or imposition of any Lien on any of the
respective properties or revenues of the Parent, the Borrower or any Subsidiary
pursuant to any such Requirement of Law or Contractual Obligation other than as
contemplated by the Security Documents.

3.6      NO MATERIAL LITIGATION . Except as set forth in SCHEDULE 3.6, no
litigation or proceeding or, to the Parent's or the Borrower's actual and
constructive knowledge, investigation of or before any arbitrator or
Governmental Authority is pending or, to the knowledge of the Parent, the
Borrower or any Subsidiary, threatened by or against the Parent, Merger Sub, or
the Borrower or any Subsidiary or against any of the respective properties or
revenues of the Parent, Merger Sub, the Borrower or any Subsidiary (a) which
purports to affect the legality, validity or enforceability of the Merger, any
Merger Document, the Thermalloy Acquisition, this Agreement or any other Loan
Document or the consummation of any transaction contemplated thereby or hereby
or (b) which could reasonably be expected to have a Material Adverse Effect.

3.7      NO DEFAULT . None of the Parent, the Borrower or any Subsidiary is in
default under, or with respect to, any of its Contractual Obligations in any
respect which could reasonably be expected to have a Material Adverse Effect. No
Default or Event of Default has occurred and is continuing.

3.8      OWNERSHIP OF PROPERTY; LIENS . Except as set forth in SCHEDULE 3.8,
each of the Parent, the Borrower and their respective Subsidiaries has good
record and marketable title in fee simple to, or a valid leasehold interest in,
all its real property, and good title to, or a valid leasehold interest in, all
its other property, other than property having a value equal to the Dollar
Equivalent of $500,000 in the aggregate. None of such property is subject to any
Lien except as permitted by SECTION 6.3. The corporate names and the
jurisdictions set forth below each such


<PAGE>

corporate name on SCHEDULE 3.8 are the only corporate names and jurisdictions
for which lien searches with respect to the assets of the Parent, Merger Sub,
the Borrower or any Domestic Subsidiary of the Borrower are necessary to confirm
such assets are not subject to any Liens, other than Liens in favor of the
Administrative Agent, for the benefit of the Lenders, or Liens permitted by
SECTION 6.3.

3.9      INTELLECTUAL PROPERTY . The Parent does not own or license any
Intellectual Property. Each of the Borrower and the Subsidiaries owns, or is
licensed to use, all trademarks, trade names, copyrights, technology, know-how,
processes, logos and insignia necessary for the conduct of its business as
currently conducted except for those which the failure to own or license could
not reasonably be expected to have a Material Adverse Effect (the "INTELLECTUAL
PROPERTY"). No claim has been asserted and is pending by any Person challenging
or questioning the use of any such Intellectual Property or the validity or
effectiveness of any such Intellectual Property, nor does the Parent, the
Borrower or any such Subsidiary know of any valid basis for any such claim. To
the knowledge of the Parent and the Borrower, the use of such Intellectual
Property by the Borrower and its Subsidiaries does not infringe on the rights of
any Person, except for such claims and infringements that, in the aggregate,
could not reasonably be expected to have a Material Adverse Effect.

3.10     NO BURDENSOME RESTRICTIONS . No Contractual Obligation of the Parent,
the Borrower or any Subsidiary could reasonably be expected to have a Material
Adverse Effect.

3.11     TAXES . Each of the Parent, the Borrower and the Subsidiaries has filed
or caused to be filed all tax returns which, to the knowledge of the Parent and
the Borrower, are required to be filed and has paid all taxes shown to be due
and payable on said returns or on any assessments made against it or any of its
property and all other taxes, fees or other charges imposed on it or any of its
property by any Governmental Authority (other than any tax, fee or other charge
the amount or validity of which is currently being contested in good faith by
appropriate proceedings and with respect to which reserves in conformity with
U.S. GAAP have been provided on the books of the Parent, the Borrower or such
Subsidiary, as the case may be); and, except as set forth in SCHEDULE 3.11, no
tax Lien has been filed, and, to the knowledge of the Parent and the Borrower,
no claim is being asserted, with respect to any such tax, fee or other charge.

3.12     FEDERAL REGULATIONS . No part of the proceeds of any Loans and no part
of any Letter of Credit will be used for "purchasing" or "carrying" any "margin
stock" within the respective meanings of each of the quoted terms under
Regulation T, U and X of the Board of Governors of the Federal Reserve System as
now and from time to time hereafter in effect or for any purpose which violates
the provisions of the Regulations of such Board of Governors. If requested by
any Lender or the Administrative Agent, the Borrower will furnish to the
Administrative Agent and each Lender a statement to the foregoing effect in
conformity with the requirements of FR Form G-1 and FR Form U-1. No proceeds of
any Loan or drawings under any Letter of Credit will be used to acquire any
equity security of a class that is registered pursuant to Section 12 of the
Securities Exchange Act of 1934.
<PAGE>


3.13     ERISA . None of the Parent, the Borrower or any Subsidiary maintains
or contributes to any Plan other than those listed on SCHEDULE 3.13. Except as
disclosed in SCHEDULE 3.13, none of the Parent, the Borrower or any Subsidiary
maintains, contributes to or has any material obligation with respect to, any
welfare plan (as defined in Section(3)(1) of ERISA) which provides benefits to
employees after termination of employment other than as required by Part 6 of
Title I of ERISA or similar state laws regarding continuation of benefits.
Except as disclosed on SCHEDULE 3.13, each Plan has complied and is in
compliance in all material respects with the applicable provisions of ERISA and
the Code. None of the Parent, the Borrower or any Subsidiary has breached any of
the responsibilities, obligations or duties imposed on it by ERISA, the Code, or
regulations promulgated thereunder with respect to any Plan, which breach could
reasonably be expected to have a Material Adverse Effect. None of the Parent,
the Borrower or any Subsidiary nor any fiduciary of any Plan who is an officer
or an employee of the Parent, the Borrower or any Subsidiary has engaged in a
nonexempt prohibited transaction described in Section 406 of ERISA or 4975 of
the Code with respect to a Plan which could reasonably be expected to have a
Material Adverse Effect. With respect to any employee benefit plan (as defined
in Section 3(3) of ERISA) currently or formerly maintained or contributed to by
any Commonly Controlled Entity, no liability exists and no event has occurred
which could subject the Parent, the Borrower or any Subsidiary to any liability.
Except as disclosed on SCHEDULE 3.13, none of the Parent, the Borrower or any
Subsidiary has maintained, contributed to, or had an obligation to contribute to
any Multiemployer Plan or any Single Employer Plan, at any time during the six
years prior to the date on which this representation is made or deemed made.
Except as disclosed on SCHEDULE 3.13, none of the Parent, the Borrower or any
Subsidiary has any material obligation to make any payment to any employee
pursuant to any existing employment contract or arrangement. The Parent and the
Borrower have given to the Administrative Agent copies of all the following:
each Single Employer Plan and related trust agreement (including all amendments
to such Plan and trust) in existence as of the Effective Date and the most
recent summary plan description, actuarial report, determination letter issued
by the IRS and Form 5500 (including all schedules thereto) filed in respect of
each existing Single Employer Plan; a listing of all the Multiemployer Plans
with the aggregate amount of the most recent annual contributions required to be
made by the Parent, the Borrower or any Subsidiary to each such Multiemployer
Plan, the most recent information which has been provided to the Parent, the
Borrower or any Subsidiary regarding withdrawal liability under any
Multiemployer Plan and the collective bargaining agreement pursuant to which
such contribution is required to be made. Except as disclosed in SCHEDULE 3.13,
none of the Parent, the Borrower or any Subsidiary has liability, direct or
indirect, contingent or otherwise, under Section 4201 or 4204 or 4212(c) of
ERISA. None of the Parent, the Borrower or any Subsidiary has any outstanding
liability in respect of (i) a failure to make a required contribution or payment
to a Multiemployer Plan or (ii) a complete or partial withdrawal under Section
4203 or 4205 of ERISA from such a plan.

3.14     HOLDING COMPANY; INVESTMENT COMPANY ACT; OTHER REGULATIONS . None of
the Parent, the Borrower or any Subsidiary is a "holding company", a "subsidiary

on behalf of the Parent, Heat Holdings II, the Borrower or any Subsidiary in
connection with the negotiation, preparation or execution of this Agreement, or
any information or data contained in the Proxy Statement or the Offering

Effect, all the foregoing are in full force and effect, and each of the Borrower
and the Subsidiaries is in substantial compliance with the foregoing without any
known conflict with the valid rights of others. No event has occurred which
permits, or after notice or lapse of time or both would permit, the revocation

be expected to have a Material Adverse Effect.

Required Lenders, the Administrative Agent may, or upon the request of the
Required Lenders, the Administrative Agent shall, by notice to the Borrower,
declare the Loans hereunder (with accrued interest thereon) and all other
amounts owing under this Agreement and the Notes to be due and payable
forthwith, whereupon the same shall immediately become due and payable. Except
as expressly provided above in this Section, presentment, demand, protest and
all other notices of any kind are hereby expressly waived.

                             ARTICLE 8. GUARANTEE

8.1      PARENT GUARANTEE . In consideration for the Lenders extending the
Commitments and in order to induce the Lenders to make the Loans to the
Borrower, the Parent hereby unconditionally guarantees (the "Parent Guarantee")
the due and punctual payment of all Obligations of the Borrower or any other
Loan Party (including with respect to principal, interest, fees, costs or
expenses) when due and at all times thereafter, in cash, whether by required
prepayment, voluntary prepayment, declaration, acceleration, demand or
otherwise, and whether such Obligation is now existing or hereafter arising,
under or in connection with this Agreement, any Note or any other Loan Document.
In addition, the Parent hereby indemnifies and holds harmless the Administrative
Agent and each Lender for any and all costs and expenses (including reasonable
attorney's fees and expenses) incurred in enforcing any rights under the Parent
Guarantee.

8.2      CONTINUING GUARANTEE . The Parent agrees that the Parent Guarantee is a
continuing guaranty and that the Obligations of the Borrower may be extended,
compromised or renewed, in whole or in part, without notice to or further assent
from the Parent, and that the Parent shall remain bound upon the Parent
Guarantee notwithstanding any extension, compromise, renewal or other alteration
of any Obligation. The Parent waives presentation to, demand of, payment from
and protest of any Obligation to the Borrower, or any other Loan Party and also
waives notice of protest for non-payment. The obligations of the Guarantor under
the Parent Guarantee shall not be affected by

     (a)  the failure of the Administrative Agent, any Lender, or the holder of
          any Note


<PAGE>


               (i) to assert any claim or demand or to enforce any right or
          remedy against the Borrower or any Subsidiary under the provisions of
          this Agreement, the Notes, any other Loan Document or otherwise, or

               (ii) to exercise any right or remedy against any other guarantor
          of, or collateral securing, any Obligation;

     (b)  any extension, compromise or renewal of any Obligation of the
          Borrower;

     (c)  any rescission, waiver, amendment or modification of any of the terms
          or provisions of this Agreement, any Note, or any Loan Document; or

     (d)  the release of any collateral held by the Administrative Agent or any
          Lender securing any Obligation.

The Parent further agrees that the Parent Guarantee constitutes a guaranty of
payment when due (upon the earlier of demand by the Administrative Agent or any
Lender, at stated maturity or upon acceleration (in whole or in part) pursuant
to SECTION 7.1) and not of collection and waives any right to require that any
resort be had by the Administrative Agent, any Lender or the holder of any Note
to the Borrower or any other Person, to any collateral held as security for the
payment of any Obligation or to any balance of any deposit account or credit on
its books in favor of the Borrower or any other Person. The obligations of the
Parent under the Parent Guarantee shall not be discharged or impaired or
otherwise affected (in any way whatsoever) by any reduction, limitation,
impairment or termination of the Obligations of the Borrower for any reason,
including any claim of waiver, release, surrender, alteration or compromise, and
shall not be subject to (and the Parent hereby waives any right to or claim of)
any defense or setoff, counterclaim, recoupment or termination whatsoever by
reason of the invalidity, illegality, nongenuineness, irregularity, compromise,
or unenforceability of the Obligations of the Borrower or otherwise. Without
limiting the generality of the foregoing, unless otherwise agreed in writing
pursuant to SECTION 10.1, the obligations of the Parent under the Parent
Guarantee shall not be discharged or impaired or otherwise affected by the
failure of the Administrative Agent, any Lender or the holder of any Note to
assert any claim or demand or to enforce any remedy under this Agreement or any
other Loan Document, by any waiver or modification, of any thereof, by any
default, failure or delay, wilful or otherwise, in the performance of any
Obligations, or by any other act or thing or omission or delay to do any other
act or thing which may or might in any manner or to any extent vary the risk of
the Parent as a guarantor or would otherwise operate as a discharge of the
Parent as a guarantor as a matter of law or equity.

8.3      REINSTATEMENT. The Parent agrees that the Parent Guarantee shall
continue to be effective or be reinstated, as the case may be, if at any time,
all or any portion of any payment (whether in respect of principal, interest,
fees, costs, expenses or other amounts payable under this Agreement, any Note or
any other Loan Document), is rescinded or must otherwise be restored by the
Administrative Agent, any Lender or the holder of any Note upon the bankruptcy


<PAGE>


or reorganization of the Borrower or otherwise. For so long as any of the
Obligations of the Borrower shall remain outstanding or any Commitments shall
remain in effect:

     (a)  all rights of the Parent against the Borrower or any other Subsidiary,
     whether arising as a result of rights of subrogation or otherwise, shall in
     all respects be subordinate and junior in right of payment to the prior
     indefeasible payment in full of all the Obligations to the Administrative
     Agent, the Lenders and other holders of Notes, and, in the event the Parent
     receives any payment prior to such indefeasible payment in full, the Parent
     shall receive such payment in trust for, and shall immediately turn over
     all amounts to, the Administrative Agent, for application to the payment of
     such Obligations;

     (b)  the Parent shall refrain from taking any action or commencing any
     proceeding against the Borrower (or its successors or assigns, whether in
     connection with a bankruptcy proceeding or otherwise) to recover any
     amounts in respect of payments made under the Parent Guarantee to the
     Administrative Agent, any Lender or any holder of any Note; and

     (c)  the Parent hereby waives any claim, right or remedy which the Parent
     may now have or may hereafter acquire against the Borrower or any
     Subsidiary that arises hereunder and/or from the performance by the Parent
     hereunder including, without limitation, any claim, remedy or right of
     subrogation, reimbursement, exoneration, contribution, indemnification or
     participation in any claim, right or remedy of the Lenders or the
     Administrative Agent against the Borrower or any Subsidiary or any security
     which the Lenders or the Administrative Agent now have or hereafter
     acquire, whether or not such claim, right or remedy arises in equity, under
     contract, by statute, under common law or otherwise.


                            ARTICLE 9. THE AGENTS

9.1      APPOINTMENT . Each Lender hereby irrevocably designates and appoints
Canadian Imperial Bank of Commerce as Administrative Agent and Bank Boston N.A.,
as Documentation Agent, in each case of such Lender under this Agreement and the
other Loan Documents. Each Lender hereby irrevocably authorizes Canadian
Imperial Bank of Commerce, as the Administrative Agent for such Lender, to serve
as security trustee for each Lender, to take such action on behalf of each
Lender under the provisions of this Agreement and the other Loan Documents and
to exercise such powers and perform such duties as are expressly delegated to
the Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Agents shall not have any duties or responsibilities, except those expressly set
forth herein, or any fiduciary relationship with any Lender, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities shall
be read into this Agreement or any other Loan Document or otherwise exist
against any Agent.


<PAGE>


9.2      DELEGATION OF DUTIES . The Administrative Agent may execute any of its
duties, rights or remedies under this Agreement and the other Loan Documents by
or through agents or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to such duties. The Administrative
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 . None of the Agents nor any of its respective
officers, directors, employees, agents, attorneys-in-fact or Affiliates (a)
shall be (i) liable for any action lawfully taken or omitted to be taken by it
or such Person under or in connection with this Agreement or any other Loan
Document (except for its or their own gross negligence or willful misconduct) or
(ii) responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by the Borrower, any other Loan
Party or any officer or any of them contained in this Agreement or any other
Loan Document or in any certificate, report, statement or other document
referred to or provided for in, or received by such Agent under or in connection
with, this Agreement or any other Loan Document or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
the Notes or any other Loan Document or the perfection or priority of any Lien
created or purported to be created thereunder, or for any failure of the
Borrower or any other Loan Party to perform its obligations hereunder or
thereunder. The Agents shall not be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of any Loan Party.

      (b) The Lead Arranger, as such, shall have no duties or obligations
whatsoever with respect to this Agreement, the Notes or any other document or
any matter related thereto.

9.4      RELIANCE BY ADMINISTRATIVE AGENT . The Administrative Agent shall be
entitled to rely, and shall be fully protected in relying, upon any Note,
writing, resolution, notice, consent, certificate, affidavit, letter, telecopy,
telex or teletype message, statement, order or other 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 Parent or the Borrower),
independent accountants and other experts selected by the Administrative Agent.
The Administrative Agent may deem and treat the payee of any Note as the owner
thereof for all purposes unless a written notice of assignment, negotiation or
transfer thereof shall have been filed with the Administrative Agent. The
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Required Lenders as it deems
appropriate or it shall first be indemnified to its satisfaction by the Lenders
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action. The Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting, under
this Agreement and the Notes and the other Loan Documents in accordance with a
request of the Required Lenders, and


<PAGE>


such request and any action taken or failure to act pursuant thereto shall be
binding upon all the Lenders and all future holders of the Notes.

9.5      NOTICE OF DEFAULT . The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default
unless the Administrative Agent has received notice from a Lender or the
Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default". In the event that
the Administrative Agent receives such a notice, the Administrative Agent shall
give notice thereof to the Lenders. The Administrative Agent shall take such
action with respect to such Default or Event of Default as shall be reasonably
directed by the Required Lenders; PROVIDED that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable in the best interests of the Lenders.

9.6      NON-RELIANCE ON AGENTS AND OTHER LENDERS . Each Lender expressly
acknowledges that none of the Agents nor any of its respective officers,
directors, employees, agents, attorneys-in-fact or Affiliates has made any
representations or warranties to it and that no act by the Administrative Agent
hereafter taken, including any review of the affairs of the Borrower, shall be
deemed to constitute any representation or warranty by the Agents to any Lender.
Each Lender represents to the Agents that it has, independently and without
reliance upon the Agents or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of the Parent, the Borrower and its Subsidiaries
made its own decision to make its Loans hereunder and enter into this Agreement.
Each Lender also represents that it will, independently and without reliance
upon the Agents or any other Lender, and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
analysis, appraisals and decisions in taking or not taking action under this
Agreement and the other Loan Documents, and to make such investigation as it
deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of the Parent, the Borrower
and the Subsidiaries. Except for notices, reports and other documents expressly
required to be furnished to the Lenders by the Agents hereunder or furnished to
the Administrative Agent for the account of, or with a counterpart or copy for,
each Lender, no Agent shall have any duty or responsibility to provide any
Lender with any credit or other information concerning the business, operations,
property, condition (financial or otherwise), prospects or creditworthiness of
the Parent, the Borrower and the Subsidiaries which may come into its possession
or any officer, director, employee, agent, attorney-in-fact or Affiliate.

9.7     INDEMNIFICATION . The Lenders agree to indemnify each Agent in its
capacity as such (to the extent not reimbursed by the Parent and the Borrower
and without limiting the obligation of the Parent and the Borrower to do so),
ratably according to their respective aggregate Commitment Percentages in effect
on the date on which indemnification is sought


<PAGE>


under this Section (or, if indemnification is sought after the date upon which
the Commitments shall have terminated and the Loans shall have been paid in
full, ratably in accordance with their Commitment Percentages immediately prior
to such date), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever which may at any time (including, without limitation, at
any time following the payment of the Notes) be imposed on, incurred by or
asserted against any Agent in any way relating to or arising out of this
Agreement, any of the other Loan Documents or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
or any action taken or omitted by any Agent under or in connection with any of
the foregoing; PROVIDED that no Lender shall be liable for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting solely from such
Agent's gross negligence or willful misconduct. The agreements in this Section
shall survive the payment of the Obligations hereunder.

9.8     AGENT IN ITS INDIVIDUAL CAPACITY . Each Agent and its respective
Affiliates may make loans to, accept deposits from and generally engage in any
kind of business with any of the Parent, the Borrower or the Subsidiaries as
though such Agent were not acting in such capacity hereunder and under the other
Loan Documents. With respect to Credit Extensions made or renewed by it and any
Note issued to it, the Administrative Agent shall have the same rights and
powers under this Agreement and the other Loan Documents as any Lender and may
exercise the same as though it were not the Administrative Agent, and the terms
"Lender" and "Lenders" shall include the Administrative Agent in its individual
capacity.

9.9     SUCCESSOR AGENTS . The Administrative Agent may resign as
Administrative Agent upon 20 days' notice to the Lenders and the Borrower. If
the Administrative Agent shall resign or be terminated, as the case may be, as
Administrative Agent under this Agreement and the other Loan Documents, then the
Required Lenders shall appoint a successor Administrative Agent who shall be
reasonably acceptable to the Borrower (so long as no Event of Default shall have
occurred which is continuing), whereupon such successor Administrative Agent
shall succeed to the rights, powers and duties of the Administrative Agent, and
the term "Administrative Agent" shall mean such successor Administrative Agent
effective upon such appointment and approval, and the former Administrative
Agent's rights, powers and duties as the Administrative Agent shall be
terminated, without any other or further act or deed on the part of such former
Administrative Agent or any of the parties to this Agreement or any holders of
the Notes. After the Administrative Agent's resignation or termination, as
Administrative Agent, the provisions of this Section shall inure to the benefit
of the Administrative Agent, as to any actions taken or omitted to be taken by
it while it was the Administrative Agent, under this Agreement and the other
Loan Documents.

9.10      RELEASE OF COLLATERAL . Each of the Agents and the Lenders hereby
directs, in accordance with the terms hereof, the Administrative Agent to
release any Lien held by the Administrative Agent for the benefit of the
Lenders:


<PAGE>


         (i)      against all of the Collateral, upon final payment in full of
         the Obligations and termination hereof; and

         (ii)      against any part of the Collateral sold or disposed of by the
         Parent, the Borrower or any Subsidiary, if such sale or disposition is
         permitted by SECTION 6.6.

(b)      Each of the Lenders hereby directs the Administrative Agent to execute
and deliver or file such termination and partial release statements and do such
other things as are necessary to release Liens to be released pursuant to this
SECTION 9.10 promptly upon the effectiveness of any such release.

(c)      Without in any manner limiting the Administrative Agent's authority to
act without any specific or further authorization or consent by any of the
Lenders (as set forth in clause (a) above), each Lender agrees to confirm in
writing, upon request by the Administrative Agent, the authority to release
Collateral conferred upon the Administrative Agent under (i) and (ii) of clause
(a) above. So long as no Event of Default is then continuing, upon receipt by
the Administrative Agent of any such written confirmation from the Lenders of
the Administrative Agent's authority to release any particular items or types of
Collateral, and in any event upon any sale and transfer of Collateral which is
expressly permitted pursuant to the terms of this Agreement, the Administrative
Agent shall (and is hereby irrevocably authorized by the Lenders to) execute
such documents as may be necessary to evidence the release of the Liens upon
such Collateral granted to the Administrative Agent for the benefit of the
Lenders; PROVIDED that (i) the Administrative Agent shall not be required to
execute any such document on terms which, in the Administrative Agent's opinion
would expose the Administrative Agent to liability or create any obligation or
entail any consequence other than the release of such Liens without recourse or
warranty, and (ii) such release shall not in any manner discharge, affect or
impair the Obligations or any Liens upon (or obligations of any Parent, the
Borrower or any Subsidiary in respect of) all interests retained by any Parent,
the Borrower or any Subsidiary, including without limitation the proceeds of any
sale, all of which shall continue to constitute part of the Collateral.

other or further exercise thereof or the exercise of any other right, remedy,
power or privilege. The rights, remedies, powers and privileges herein
provided are cumulative and not exclusive of any rights, remedies, powers and
privileges provided by law.

hold harmless each Lender and the Agents from, any and all recording and filing

clause (d), collectively, the "indemnified liabilities"); PROVIDED that the
Parent and the Borrower shall not have any obligation hereunder to any Agent
or any Lender with respect to indemnified liabilities arising from the gross
negligence or willful misconduct of such Agent or such Lender. The agreements
in this SECTION 10.5 shall survive repayment of the Obligations hereunder.

10.6      SUCCESSORS AND ASSIGNS; PARTICIPATIONS AND ASSIGNMENTS . (a) This
Agreement shall be binding upon and inure to the benefit of the Parent, Heat
Holdings II, the Borrower, the Lenders, the Issuer, the Administrative Agent,
all future holders of the Notes and their respective successors and assigns,
except that none of such Loan Parties may assign or transfer any of its
rights or obligations under this Agreement without the prior written consent
of each Lender.

(b)      Any Lender may, in the ordinary course of its lending business and in
accordance with applicable law, at any time sell to one or more banks or other
entities ("PARTICIPANTS") participating interests in any Loan owing to such
Lender, any Note held by such Lender, any Commitment of such Lender or any other
interest of such Lender hereunder and under the other Loan Documents; PROVIDED
that after giving effect to any such sale, such Lender must have either (x)
retained at least $2,500,000 of Commitments not subject to any participating
interests or (y) sold participating interests to Participants in all its Loans
and Commitments. In the event of any such sale by a Lender of a participating
interest to a Participant, such Lender's obligations under this Agreement to the
other parties to this Agreement shall remain unchanged, such Lender shall remain
solely responsible for the performance thereof, such Lender shall remain the
holder of any such Note for all purposes under this Agreement and the other Loan
Documents, and the Borrower and the Administrative Agent, shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Documents. Each of the
Parent, Heat Holdings II, and the Borrower agrees that if amounts outstanding
under this Agreement and the Notes are due or unpaid, or shall have been
declared or shall have become due and payable upon the occurrence of an Event of
Default, each Participant shall be deemed to have the right of setoff in respect
of its participating interest in amounts owing under this Agreement and any Note
to the same extent as if the amount of its participating interest were owing
directly to it as a Lender under this Agreement or any Note; PROVIDED that, in
purchasing such participating interest, such Participant shall be deemed to have
agreed to share with the Lenders the proceeds thereof as provided in SECTION
10.7(a) as fully as if it were a Lender hereunder. Each of the Parent, Heat
Holdings II, and the Borrower also agrees that each Participant shall be
entitled to the benefits of SECTION 2.17, SECTION 2.18, SECTION 2.19, with
respect to its participation in the Commitments and the Loans outstanding from
time to time as if it were a Lender; PROVIDED that, in the case of SECTION 2.18
or such Participant shall have complied with the requirements of such Section
and PROVIDED, FURTHER, that no Participant shall be entitled to receive any
greater amount pursuant to any such Section than the transferor Lender would
have been entitled to receive in respect of the amount of the participation
transferred by such transferor Lender to such Participant had no such transfer
occurred.


<PAGE>


(c)      Any Lender may, in the ordinary course of its lending business and in
accordance with applicable law, at any time and from time to time assign to any
Lender or any affiliate thereof or, with the consent of the Borrower (which
consent shall not be unreasonably withheld and shall not be required if an Event
of Default shall have occurred) and with the consent of the Administrative Agent
(which consent shall not be unreasonably withheld), to an additional bank or
financial institution (an "ASSIGNEE") all or any part of its rights and
obligations under this Agreement and the Notes pursuant to a Commitment Transfer
Supplement, substantially in the form of EXHIBIT Y (a "COMMITMENT TRANSFER
SUPPLEMENT") executed by such Assignee, such assigning Lender (and, in the case
of an Assignee that is not then a Lender or an affiliate thereof, by the
Borrower (so long as no Event of Default shall have occurred which is
continuing) and the Administrative Agent) and delivered to the Administrative
Agent for its acceptance and recording in the Register; PROVIDED that (i) any
such assignment must (unless to an institution which was a Lender immediately
prior thereto) be in a minimum amount equal to the lesser of (x) $2,500,000 (or
such lesser amount as may be acceptable to the Administrative Agent and the
Borrower (so long as no Event of Default shall have occurred which is
continuing)) and whole multiples of $1,000,000 in excess thereof, and (y) the
aggregate Commitments and outstanding Loans of such Lender then in effect, and
(ii) after giving effect to any such assignment, such Lender shall have either
(x) sold all its rights and obligations hereunder and under the Notes or (y)
retained at least $2,500,000 of the aggregate Commitments. Upon such execution,
delivery, acceptance and recording, from and after the effective date determined
pursuant to such Commitment Transfer Supplement, (1) the Assignee thereunder
shall be a party hereto and, to the extent provided in such Commitment Transfer
Supplement, have the rights and obligations of a Lender hereunder with a
Commitment as set forth therein and (2) the assigning Lender thereunder, to the
extent provided in such Commitment Transfer Supplement, shall be released from
its obligations under this Agreement (and, in the case of a Commitment Transfer
Supplement covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement, such assigning Lender shall cease to be a
party hereto; PROVIDED that the provisions of SECTION 2.17, SECTION 2.18,
SECTION 2.19, and SECTION 10.5 shall continue to benefit such assigning Lender
to the extent required by such Sections).

(d)      The Administrative Agent shall maintain, at its address referred to in
SECTION 10.2, a copy of each Commitment Transfer Supplement delivered to it and
a register (the "REGISTER") for the recordation of the names and addresses of
the Lenders and the Commitments of, and principal amount of the Loans owing to,
each Lender from time to time. The entries in the Register shall be conclusive,
in the absence of manifest error, and the Parent, Heat Holdings II, the
Borrower, the Administrative Agent and the Lenders may treat each Person whose
name is recorded in the Register as the owner of the Loan recorded therein for
all purposes of this Agreement. The Register shall be available for inspection
by the Parent, Heat Holdings II, the Borrower or any Lender at any reasonable
time and from time to time upon reasonable prior notice.





<PAGE>


(e)      Upon its receipt of a Commitment Transfer Supplement executed by an
assigning Lender and an Assignee (and, in the case of an Assignee that is not
then a Lender or an affiliate thereof, by the Borrower and the Administrative
Agent) together with payment to the Administrative Agent of a registration and
processing fee of $3,500, the Administrative Agent shall promptly accept such
Commitment Transfer Supplement and, on the effective date determined pursuant
thereto, shall record the information contained therein in the Register and give
notice of such acceptance and recordation to the Lenders and the Borrower. On or
prior to such effective date, the Borrower, at its own expense, shall execute
and deliver to the Administrative Agent (in exchange for the Revolving Credit
Note, or Term Note of the assigning Lender) a new Revolving Credit Note, or Term
Note, as the case may be, to the order of such Assignee in an amount equal to
the Revolving Credit Commitment, or Term Loan, as the case may be, assumed by
such Assignee pursuant to such Commitment Transfer Supplement and, if the
assigning Lender has retained a Revolving Credit Commitment, or Term Loan,
hereunder, a new Revolving Credit Note or Term Note, as the case may be, to the
order of the assigning Lender in an amount equal to the Revolving Credit
Commitment or Term Loan, as the case may be, retained by it hereunder. Such new
Notes shall be dated the Effective Date and shall otherwise be in the form of
the Notes replaced thereby.

(f)      Each of the Parent, Heat Holdings II and the Borrower authorizes each
Lender to disclose to any Participant or Assignee (each, a "TRANSFEREE") and any
prospective Transferee, any and all financial information in such Lender's
possession concerning the Parent, Heat Holding II, the Borrower and their
respective Affiliates which has been delivered to such Lender by or on behalf of
such Loan Party pursuant to this Agreement or which has been delivered to such
Lender by or on behalf of such Loan Party in connection with such Lender's
credit evaluation of the Borrower and its Affiliates prior to becoming a party
to this Agreement.

(g)      Nothing herein shall prohibit any Lender from pledging or assigning any
Note to any Federal Reserve Bank in accordance with applicable law.

10.7      ADJUSTMENTS; SETOFF . (a) If any Lender (a "BENEFITTED LENDER")
shall at any time receive any payment of all or part of its Credit
Extensions, or interest thereon, or receive any collateral in respect thereof
(whether voluntarily or involuntarily, by setoff, pursuant to events or
proceedings of the nature referred to in SECTION 7.1(f), or otherwise), in a
greater proportion than any such payment to or collateral received by any
other Lender, if any, in respect of such other Lender's Credit Extensions, or
interest thereon, such Benefitted Lender shall purchase for cash from the
other Lenders a participating interest in such portion of each such other
Lender's Loans, or shall provide such other Lenders with the benefits of any
such collateral, or the proceeds thereof, as shall be necessary to cause such
Benefitted Lender to share the excess payment or benefits of such collateral
or proceeds ratably with each of the Lenders; PROVIDED that if all or any
portion of such excess payment or benefits is thereafter recovered from such
Benefitted Lender, such purchase shall be rescinded, and the purchase price
and benefits returned, to the extent of such recovery, but without interest.

<PAGE>


(b)      In addition to any rights and remedies of the Lenders provided by law,
each Lender shall have the right, without prior notice to the Borrower, Heat
Holdings II or the Parent, any such notice being expressly waived by each
Borrower, Heat Holdings II and the Parent to the extent permitted by applicable
law, upon any amount becoming due and payable by the Borrower, Heat Holdings II
or the Parent hereunder and under the Notes (whether at the stated maturity, by
acceleration or otherwise) to set off and appropriate and apply against such
amount any and all deposits (general or special, time or demand, provisional or
final) in any currency, and any other credits, indebtedness or claims, in any
currency, in each case, whether direct or indirect, absolute or contingent,
matured or unmatured, at any time held or owing by such Lender or any branch or
agency thereof to or for the credit or the account of the Borrower, Heat
Holdings II or the Parent, as the case may be. Each Lender agrees promptly to
notify the Borrower, Heat Holdings II or the Parent, as applicable, and the
Administrative Agent after any such setoff and application made by such Lender;
PROVIDED that the failure to give such notice shall not affect the validity of
such setoff and application.

10.8      CONFIDENTIALITY . Each Lender agrees to exercise all reasonable
efforts (consistent with its customary methods for keeping information
confidential) to keep any information delivered or made available by any Loan
Party confidential from anyone other than persons employed or retained by such
Lender who are or are expected to become engaged in evaluating, approving,
structuring or administering the Loans; PROVIDED, that nothing herein shall
prevent any Lender from disclosing such information (a) to any Affiliate of such
Lender or to any other Lender, (b) upon the order of any court or administrative
agency, (c) upon the request or demand of any regulatory agency or authority
having jurisdiction over such Lender, (d) that has been publicly disclosed, (e)
in connection with any litigation relating to the Loans, this Agreement or any
transaction contemplated hereby to which any Loan Party, any Lender or the
Administrative Agent may be a party, (f) to the extent reasonably required in
connection with the exercise of any remedy hereunder, (g) to such Lender's legal
counsel and independent auditors and (h) to any actual or proposed participant
or assignee of all or any part of its Loans hereunder, if such other Person,
prior to such disclosure, agrees, in writing, for the benefit of the Borrower to
comply with the provisions of this SECTION 10.8.

10.9      EFFECTIVENESS . On the Effective Date, the Existing Credit Agreement
shall be amended and restated in its entirety by this Agreement and the Existing
Credit Agreement shall thereafter be of no further force and effect.
Notwithstanding any provision of this SECTION 10.9 to the contrary, any
obligations of the Borrower which accrued on or prior to the Effective Date
under the Existing Credit Agreement shall not be released or terminated by the
effectiveness of this Agreement. The terms and conditions of this Agreement and
the Administrative Agent's and the Lenders' rights and remedies under this
Agreement shall apply to all obligations incurred under the Existing Credit
Agreement. It is expressly understood and agreed by the parties hereto that (a)
this Agreement is in no way intended to constitute a novation of the obligations
and liabilities existing under the Existing Credit Agreement and (b) the
obligations and liabilities under the Notes evidence obligations and liabilities
incurred under the Existing Credit Agreement. The Borrower reaffirms the Liens
granted to the Administrative Agent for the


<PAGE>


benefit of the Lenders pursuant to each of the Loan Documents executed by the
Borrower, which Liens shall continue in full force and effect during the term of
this Agreement and any renewals thereof and shall continue to secure the
Obligations identified in such Loan Documents. Unless expressly stated to the
contrary, all references to the Existing Credit Agreement in the Loan Documents
shall be deemed to refer to this Agreement. This Agreement and each of the other
Loan Documents shall be construed to the extent reasonable to be consistent with
the other, but to the extent that the terms and conditions of this Agreement are
actually inconsistent with the terms and conditions of any other Loan Document,
this Agreement shall govern. This Agreement shall become effective on the date
when counterparts hereof executed on behalf of the Parent, Heat Holdings II, the
Borrower and each Lender shall have been received by the Administrative Agent
and notice thereof shall have been given by the Administrative Agent to the
Parent, Heat Holdings II, the Borrower and each Lender.

10.10     COUNTERPARTS . This Agreement may be executed by one or more of the
parties to this Agreement on any number of separate counterparts (including by
telecopy), and all said counterparts taken together shall be deemed to
constitute one and the same instrument. A set of the copies of this Agreement
signed by all the parties shall be lodged with the Borrower and the
Administrative Agent.

10.11     SEVERABILITY . Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

10.12     INTEGRATION . This Agreement and the other Loan Documents represent
the agreement of the Parent, Heat Holdings II, the Borrower, the
Administrative Agent and the Lenders with respect to the subject matter
hereof and thereof, and there are no promises, undertakings, representations
or warranties by the Administrative Agent or any Lender relative to subject
matter hereof or thereof not expressly set forth or referred to herein or in
the other Loan Documents.

10.13     GOVERNING LAW . THIS AGREEMENT AND THE NOTES AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT AND THE NOTES SHALL BE
GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE
STATE OF NEW YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS
THEREOF OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE STATE
OF NEW YORK.

10.14     SUBMISSION TO JURISDICTION; WAIVERS . Each of the Parent, Heat
Holdings II and the Borrower hereby irrevocably and unconditionally:

<PAGE>


         (a)      submits for itself and its property in any legal action or
         proceeding relating to this Agreement and the other Loan Documents to
         which it is a party, or for recognition and enforcement of any judgment
         in respect thereof, to the non-exclusive general jurisdiction of the
         Courts of the State of New York, the courts of the United States of
         America for the Southern District of New York, and appellate courts
         from any thereof;

and (iii) of the preceding sentence within 30 days of the occurrence of any such
event. The Borrower hereby authorizes the Administrative Agent to modify this
Agreement unilaterally (i) by amending SCHEDULE A to include any future patents,
trademarks, registered trademarks, trademark applications, service marks, patent
applications, registered service marks and service mark applications owned or
held by Borrower or to prepare this Agreement for filing with the Patent and
Trademark Office and by amending SCHEDULE B to include any patent license

Trademark Office, in addition to and not in substitution for this Agreement, a

marks and service mark applications, and patent license agreements, trademark
license agreements and service mark license agreements.

Administrative Agent of the Patents, Trademarks and Licenses as authorized
hereunder in connection with the Administrative Agent's exercise of its rights
and remedies under PARAGRAPH 13 or pursuant to the Security Agreements shall be
coextensive with the Borrower's rights thereunder and with respect thereto and
without any liability for royalties or other related charges from the
Administrative Agent and the Lenders to the Borrower.

                  6.  FURTHER ASSIGNMENTS AND SECURITY INTERESTS. The Borrower
agrees not to sell or assign its respective interests in, or grant any license
under, the Patents, the Trademarks or the Licenses without the prior and express
written consent of the Administrative Agent.


                                      4

<PAGE>

                  7.  Nature and Continuation of the Administrative Agent's
Security Interest; Termination of the Administrative Agent's Security Interest;
Release of Collateral. This Agreement is made for collateral security purposes
only. This Agreement shall create a continuing security interest in the Patents,
Trademarks and Licenses and shall terminate only when the Obligations have been
paid in full in cash and the Credit Agreement and the Security Agreements have
been terminated. Upon such termination and at the written request of the
Borrower or its successors or assigns, and at the cost and expense of the
Borrower or its successors or assigns, the Administrative Agent shall execute in
a timely manner such instruments, documents or agreements as are necessary or
desirable to terminate the Administrative Agent's security interest in the
Patents, the Trademarks and the Licenses, subject to any disposition thereof
which may have been made by the Administrative Agent pursuant to this Agreement
or the Security Agreements.

                  8.  DUTIES OF THE BORROWER. Subject to the second sentence of
this Section 8, the Borrower shall have the duty (i) to prosecute diligently any
patent application, trademark application or service mark application that is
part of the Trademarks pending as of the date hereof or hereafter until the
termination of this Agreement and (ii) to make any application for and
diligently prosecute the registration of (x) any trademark or service mark that
the Borrower has not created as of the date hereof which the Administrative
Agent, after consultation with the Borrower, reasonably determines may have
significant value and (y) any unpatented but patentable invention. The Borrower
further agrees (i) not to abandon any Trademark or License without the prior
written consent of the Administrative Agent if such abandonment would have a
Material Adverse Effect, and (ii) to use its reasonable best efforts to obtain
and maintain in full force and effect the Patents, the Trademarks and the
Licenses that are or shall be necessary or economically desirable in the
operation of the Borrower's business. Any expenses incurred in connection with
the foregoing shall be borne by the Borrower. Neither the Administrative Agent
nor any of the Lenders shall have any duty with respect to the Patents,
Trademarks and Licenses. Without limiting the generality of the foregoing,
neither the Administrative Agent nor any of the Lenders shall be under any
obligation to take any steps necessary to preserve rights in the Patents, the
Trademarks or Licenses against any other parties, but the Administrative Agent
may do so at its option from and after the occurrence of an Event of Default,
and all expenses incurred in connection therewith shall be for the sole account
of the Borrower and shall be added to the Obligations secured hereby.

                  9.  THE ADMINISTRATIVE AGENT'S RIGHT TO SUE. Upon the
occurrence and during the continuance of an Event of Default, the Administrative
Agent shall have the right, but shall not be obligated, to bring suit in its own
name to enforce the Patents, the Trademarks and the Licenses and, if the
Administrative Agent shall commence any such suit, the Borrower shall, at the
request of the Administrative Agent, do any and all lawful acts and execute any
and all proper documents required by the Administrative Agent in aid of such
enforcement. The Borrower shall, upon demand, promptly reimburse the
Administrative Agent for all actual costs and expenses incurred by the
Administrative Agent in the exercise of its rights under this PARAGRAPH 9
(including, without limitation, reasonable fees and expenses of counsel for the
Administrative Agent).

                  10. WAIVERS. The Administrative Agent's failure, at any time
or times hereafter, to require strict performance by the Borrower of any
provision of this Agreement shall


                                      5
<PAGE>

not waive, affect or diminish any right of the Administrative Agent
thereafter to demand strict compliance and performance therewith nor shall
any course of dealing between the Borrower and the Administrative Agent have
such effect. No single or partial exercise of any right hereunder shall
preclude any other or further exercise thereof or the exercise of any other
right. None of the undertakings, agreements, warranties, covenants and
representations of the Borrower contained in this Agreement shall be deemed
to have been suspended or waived by the Administrative Agent unless such
suspension or waiver is in writing signed by an officer of the Administrative
Agent and directed to the Borrower specifying such suspension or waiver.

                  11. SEVERABILITY. If any provision of this Agreement is held
to be prohibited or unenforceable in any jurisdiction the substantive laws of
which are held to be applicable hereto, such prohibition or unenforceability
shall not affect the validity or enforceability of the remaining provisions
hereof and shall not invalidate or render unenforceable such provision in any
other jurisdiction.

                  12. MODIFICATION. This Agreement cannot be altered, amended or
modified in any way, except as specifically provided in PARAGRAPH 4 hereof or by
a writing signed by the parties hereto.

                  13. CUMULATIVE REMEDIES; POWER OF ATTORNEY. The Borrower
agrees, upon the request of the Administrative Agent and promptly following such
request, to take any action and execute any instrument which the Administrative
Agent may deem necessary or advisable to accomplish the purposes of this
Agreement. The Borrower hereby irrevocably designates, constitutes and appoints
the Administrative Agent (and all Persons designated by the Administrative Agent
in its sole and absolute discretion) as the Borrower's true and lawful
attorney-in-fact, and authorizes the Administrative Agent and any of the
Administrative Agent's designees, in the Borrower's or the Administrative
Agent's name, from and after the occurrence and during the continuance of an
Event of Default, to take any action and execute any instrument which the
Administrative Agent may deem necessary or advisable to accomplish the purposes
of this Agreement, including, without limitation, (i) to endorse the Borrower's
name on all applications, documents, papers and instruments necessary or
desirable for the Administrative Agent in the use, prosecution or protection of
the Patents, the Trademarks or the Licenses, (ii) to assign, pledge, convey or
otherwise transfer title in or dispose of the Trademarks or the Licenses to
anyone on commercially reasonable terms, (iii) to grant or issue any exclusive
or nonexclusive license under the Patents, the Trademarks or the Licenses, to
anyone on commercially reasonable terms, and (iv) to take any other actions with
respect to the Patents or the Trademarks or, to the extent permitted, the
Licenses as the Administrative Agent deems in its own or the Lenders' best
interest. The Borrower hereby ratifies all that such attorney shall lawfully do
or, to the extent permitted, cause to be done by virtue hereof. This power of
attorney is coupled with an interest and shall be irrevocable until all the
Obligations shall have been paid in full in cash and the Credit Agreement shall
have been terminated. The Borrower acknowledges and agrees that this Agreement
is not intended to limit or restrict in any way the rights and remedies of the
Administrative Agent or the other Lenders under the Agreement, but rather is
intended to facilitate the exercise of such rights and remedies.

                  The Administrative Agent shall have, in addition to all
other rights and remedies given it by the terms of this Agreement, all rights
and remedies allowed by law and the rights

                                      6

<PAGE>

and remedies of a secured party under the Uniform Commercial Code as enacted
in any jurisdiction in which the Trademarks or the Licenses may be located or
deemed located. If an Event of Default has occurred and is continuing and the
Administrative Agent has elected to exercise any of its remedies under
Section 9-504 or Section 9-505 of the Uniform Commercial Code with respect to
the Patents, Trademarks and Licenses, the Borrower agrees to assign, convey
and otherwise transfer all of its title in and to the Patents, the Trademarks
and the Licenses to the Administrative Agent or any transferee of the
Administrative Agent and to execute and deliver to the Administrative Agent
or any such transferee all such agreements, documents and instruments as may
be necessary, in the Administrative Agent's sole discretion, to effect such
assignment, conveyance and transfer; PROVIDED that in the case of any
Patents, Trademarks and Licenses licensed to the Borrower by third parties,
such transfer shall be solely to the extent any of the foregoing are
transferable pursuant to operative agreements between the Borrower and such
third party. All the Administrative Agent's rights and remedies with respect
to the Patents, the Trademarks and the Licenses, whether established hereby,
by the Security Agreements, by any other agreements or by law, shall be
cumulative and may be exercised separately or concurrently. Notwithstanding
anything set forth herein to the contrary, it is hereby expressly agreed that
if an Event of Default has occurred and is continuing, the Administrative
Agent may exercise any of the rights and remedies provided in this Agreement,
the Security Agreements and any of the other Loan Documents. The Borrower
agrees that any notification of intended disposition of any of the Patents,
Trademarks and Licenses required by law shall be deemed reasonably and
properly given if given at least ten (10) days before such disposition;
PROVIDED, that the Administrative Agent may give any shorter notice that is
commercially reasonable under the circumstances.

                  14. SUCCESSORS AND ASSIGNS. This Agreement shall be binding

successors and assigns shall include, without limitation, a receiver, trustee or
debtor-in-possession of or for the Borrower; PROVIDED, that the Borrower shall
not voluntarily assign or transfer its rights or obligations hereunder without
the Administrative Agent's prior written consent.

                  15. GOVERNING LAW. This Agreement shall be governed by, and be
construed and interpreted in accordance with, the law (without regards to
conflict of law provisions (other than Section 5-1401 of the General Obligations
Law)) of the State of New York, except for perfection and enforcement of
security interests and liens in other jurisdictions to the extent the law of
another jurisdiction is, pursuant to the laws of such jurisdiction, mandatorily
applicable.

under this Agreement with respect to any action taken by the Administrative
Agent or the exercise or non-exercise by the Administrative Agent of any option,
right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Agreement shall, as between the Administrative
Agent and the Lenders, be governed by the Credit Agreement and by such other
agreements with respect thereto as may exist from time to time among them, but,
as between the Administrative Agent


                                      7
<PAGE>

and the Borrower, the Administrative Agent shall be conclusively presumed to
be acting as agent for the Lenders with full and valid authority so to act or
refrain from acting, and the Borrower shall not be under any obligation, or
entitlement, to make any inquiry respecting such authority.

                  18. TERMINATION; RELEASE. Upon the repayment of all the
Obligations in full and the termination of the Commitments, this Agreement shall
terminate, and the Administrative Agent, at the request and expense of the
Borrower, will promptly execute and deliver to the Borrower the proper
instruments acknowledging the termination of this Agreement, and will duly
assign, transfer and deliver to Borrower (without recourse and without any
representation or warranty of any kind) such of the Collateral as may be in the
possession of the Administrative Agent and has not theretofore been disposed of
or otherwise applied or released.

                  19. REINSTATEMENT. This Agreement shall continue to be
effective or be reinstated, as the case may be, if at any time any amount
received by the Lenders in respect of the Obligations is rescinded or must
otherwise be restored or returned by such Lender upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Borrower or upon
the appointment of any intervenor or conservator of, or trustee or similar
official for, the Borrower or any substantial part of its assets, or upon the
entry of an order by a bankruptcy court avoiding payment of such amount, or
otherwise, all as though such payments had not been made.

                  20. SECTION TITLES. The section titles herein are for

Borrower hereby irrevocably and unconditionally agrees that the terms of Section
9.13 of the Credit Agreement with respect to submission to jurisdiction and
service of process shall apply equally to this Agreement.

                  23. WAIVER OF BOND. The Borrower waives the posting of any
bond otherwise required of the Administrative Agent in connection with any
judicial process or proceeding to realize on any of the Patents, Trademarks or
Licenses or any other security for the Obligations, to enforce any judgment or
other court order entered in favor of the Administrative Agent, or to enforce by
specific performance, temporary restraining order, or preliminary or permanent
injunction, this Agreement or any other agreement or document between the

                  3. RIGHTS OF ADMINISTRATIVE AGENT AND LENDERS; LIMITATIONS ON

                  (a) BORROWER REMAINS LIABLE UNDER ACCOUNTS AND CONTRACTS.
Anything herein to the contrary notwithstanding, the Borrower shall remain
liable under each of the Accounts and Contracts to observe and perform all
the conditions and obligations to be observed and performed by it thereunder,
all in accordance with the terms of any agreement giving rise to each such
Account and in accordance with and pursuant to the terms and provisions of
each such Contract. Neither the Administrative Agent nor any Lender shall
have any obligation or liability under any Account (or any agreement giving
rise thereto) or under any Contract by reason of or arising out of this
Security Agreement or the receipt by the Administrative Agent or any such
Lender of any payment relating to such Account or Contract pursuant hereto,
nor shall the Administrative Agent or any Lender be obligated in any manner
to perform any of the obligations of the Borrower under or pursuant to any
Account (or any agreement giving rise thereto) or under or pursuant to any
Contract, to make any payment, to make any inquiry as to the nature or the
sufficiency of any payment received by it or as to the sufficiency of any
performance by any party under any Account (or any agreement giving rise
thereto) or under any Contract, 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 it or to which it may be entitled at any time
or times.

                  (b) NOTICE TO ACCOUNT DEBTORS AND CONTRACTING PARTIES. At
any time after the occurrence and during the continuance of an Event of
Default, the Administrative Agent shall have the right at any time, upon
written notice to the Borrower of its intention to do so, to notify account
debtors or obligors on the Accounts and parties to the Contracts that the
Accounts and the Contracts have been assigned to the Administrative Agent for
the ratable benefit of the Lenders and that payments due or to become due to
the Borrower in respect thereof shall be made directly to the Administrative
Agent and, upon such notification, and at the expense of the Borrower, to
enforce collection of any such Accounts. The Administrative Agent may, at any
time, in its own name or in the name of the Lenders or the Borrower
communicate with account debtors on the Accounts and parties to the Contracts
to verify with them to its satisfaction the existence, amount and terms of
any Accounts or Contracts. Unless an Event of Default shall have occurred and
be continuing, the Administrative Agent shall not exercise its right under
this clause (b) more than once in any 12-month period.

                  (c) COLLECTIONS ON ACCOUNTS. The Administrative Agent
hereby authorizes the Borrower to collect the Accounts; PROVIDED that the
Administrative Agent may curtail or terminate said authority at any time
after the occurrence of an Event of Default. If required by the
Administrative Agent at any time after the occurrence and during the
continuance of an

Event of Default, any payments of Accounts, when collected by the Borrower,
shall be forthwith (and, in any event, within two Business Days) deposited by
the Borrower in the exact form received, duly endorsed by the Borrower to the
Administrative Agent if required, in a special collateral account maintained
by the Administrative Agent, subject to withdrawal by the Administrative
Agent for the account of the Lenders only, as hereinafter provided, and,
until so turned over, shall be held by the Borrower in trust for the
Administrative Agent and the Lenders, segregated from other funds of the
Borrower. Each deposit of any such Proceeds shall be accompanied by a report
identifying in reasonable detail the nature and source of the payments
included in the deposit. All Proceeds constituting collections of Accounts
while held by the Administrative Agent (or by the Borrower in trust for the
Administrative Agent and the Lenders) shall continue to be collateral
security for all the Obligations and shall not constitute payment thereof
until applied as hereinafter provided. At such intervals as may be agreed
upon by the Borrower and the Administrative Agent, or, if an Event of Default
shall have occurred and be continuing, at any time at the Administrative
Agent's election, the Administrative Agent shall apply all or any part of the
funds on deposit in said special collateral account on account of the
Obligations in such order as the Administrative Agent may elect, and any part
of such funds which the Administrative Agent elects not so to apply and deems
not required as collateral security for the obligations shall be paid over
from time to time by the Administrative Agent to the Borrower or to
whomsoever may lawfully be entitled to receive the same (it being understood
that (i) prior to any Event of Default that is continuing, the Borrower shall
be permitted to use such funds in the operation of its business in a manner
consistent with the terms of the Credit Agreement and (ii) within fifteen
days after the occurrence of any Event of Default, the Administrative Agent
shall, in its sole discretion, either apply such funds in payment of the
Obligations in such order as the Administrative Agent may elect or permit the
Borrower to use such funds in the operation of its business). Upon the
occurrence of an Event of Default that is continuing, at the Administrative
Agent's request, the Borrower shall deliver to the Administrative Agent all
original and other documents evidencing, and relating to, the agreements and
transactions which gave rise to the Accounts, including, without limitation,
all original orders, invoices and shipping receipts.

                  (d) ANALYSIS OF ACCOUNTS. The Administrative Agent shall
have the right to make test verifications of the Accounts in any manner and
through any medium that it reasonably considers advisable, and the Borrower
shall furnish all such assistance and information as the Administrative Agent
may require in connection therewith; PROVIDED that the Administrative Agent
shall use its reasonable efforts to minimize any disruption of the Borrower's
business resulting from such verifications. At any time and from time to time
if the Administrative Agent concludes in its reasonable judgment, based upon
its evaluation of the general creditworthiness of the Borrower, that such
examination is required, and so requests, the Borrower at its own expense
shall cause independent public accountants or other parties that are not
Affiliates of the Borrower and are reasonably satisfactory to the
Administrative Agent to furnish to the Administrative Agent reports showing
reconciliations, aging and test verifications of, and trial balances for, the
Accounts. Unless an Event of Default shall have occurred and be continuing,
the Administrative Agent shall not exercise its right under this clause (d)
more than once in any 12-month period.

                  4. REPRESENTATIONS AND WARRANTIES. The Borrower hereby
represents and warrants that:


                                      -5-

<PAGE>

                  (a) TITLE; NO OTHER LIENS. Except as permitted under
Section 6.3 of the Credit Agreement, the Borrower owns or has a valid
leasehold interest in each item of the Collateral free and clear of any and
all Liens or claims of others. Except as permitted under Section 6.3(e) of
the Credit Agreement, no security agreement, financing statement or other
public notice with respect to all or any part of the Collateral is on file or
of record in any public office, except (i) such as may have been filed in
favor of the Administrative Agent, for the ratable benefit of the Lenders,
pursuant to this Security Agreement and (ii) financing statements filed by
lessors solely for information purposes in respect of "true" leases.

                  (b) PERFECTED FIRST PRIORITY LIENS. Except as permitted
under Section 6.3(e) of the Credit Agreement, the Liens granted pursuant to
this Security Agreement will, upon the filing of appropriate financing
statements, constitute valid and perfected first priority Liens on the
Collateral in favor of the Administrative Agent, for the ratable benefit of
the Lenders, and against any owner or purchaser of the real property where
any of the Equipment is located and any present or future creditor obtaining
a Lien on such real property, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
the enforcement of creditor's rights generally and by general equitable
principles (whether enforcement is sought by proceedings in equity or at law).

                  (c) ACCOUNTS. The amount represented by the Borrower to the
Lenders from time to time as owing by each account debtor or by all account
debtors in respect of the Accounts will at such time be the correct amount
actually owing by such account debtor or debtors thereunder. No amount
payable to the Borrower under or in connection with any Account is evidenced
by any Instrument or Chattel Paper which has not been delivered to the
Administrative Agent. The place where the Borrower keeps its records
concerning the Accounts is One Eagle Square, Concord, New Hampshire 03301(1.)

                  (d) CONTRACTS. Except as set forth in Schedule 3.4 to the
Credit Agreement, no consent of any party (other than the Borrower) to any
Contract is required in connection with the execution, delivery and
performance by the Borrower of this Security Agreement. Each Contract is in
full force and effect and constitutes a valid and legally enforceable
obligation of the parties thereto, except as enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
the enforcement of creditor's rights generally and by general equitable
principles (whether enforcement is sought by proceedings in equity or at
law). No consent or authorization of, filing with or other act by or in
respect of any Governmental Authority is required in connection with the
execution, delivery or performance by the Borrower of, or the validity or
enforceability of, any of the Contracts by any party thereto other than those
which have been duly obtained, made or performed, are in full force and
effect and do not subject the scope of any such Contract to any material
adverse limitation, either specific or general in nature. Neither the
Borrower nor (to the best of the Borrower's knowledge) any other party to any
Contract is in default in any material respect in the performance or
observance of any of the terms thereof. The Borrower has fully performed in
all material respects all its obligations under each Contract. The right,
title and interest of the Borrower in, to and under each Contract are not
subject to any defense, offset, counterclaim or claim which would

<PAGE>

materially adversely affect the value of such Contract as Collateral, nor
have any of the foregoing been asserted or alleged against the Borrower as to
any Contract. The Borrower has delivered to the Administrative Agent a
complete and correct copy of each material Contract, including all
amendments, supplements and other modifications thereto and will deliver any
other Contract which the Administrative Agent may request. No amount payable
to the Borrower under or in connection with any Contract is evidenced by any
Instrument or Chattel Paper which has not been delivered to the
Administrative Agent.

                  (e) INVENTORY AND EQUIPMENT. The Inventory and the
Equipment are kept at the locations listed on Schedule I hereto.

                  (f) CHIEF EXECUTIVE OFFICE. The Borrower's chief executive
office and chief place of business is located at One Eagle Square, Concord,
New Hampshire 03301(2).

                  (g) FARM PRODUCTS. None of the Collateral constitutes, or
is the Proceeds of, Farm Products.

                  (h) GOVERNMENTAL OBLIGORS. None of the obligors on any
Accounts, and none of the parties to any Contracts, is a Governmental
Authority.

                  (i) INVESTMENT PROPERTY. The Investment Property consists
of the items set forth on Annex A.

                  5. COVENANTS. The Borrower covenants and agrees with the
Administrative Agent and the Lenders that, from and after the date of this
Security Agreement until the Obligations are paid in full and the Commitments
are terminated:

                  (a) FURTHER DOCUMENTATION; PLEDGE OF INSTRUMENTS AND
CHATTEL PAPER. At any time and from time to time, upon the written request of
the Administrative Agent, and at the sole expense of the Borrower, the
Borrower will promptly and duly execute and deliver such further instruments
and documents and take such further action as the Administrative Agent may
reasonably request for the purpose of obtaining or preserving the full
benefits of this Security Agreement and of the rights and powers herein
granted, including, without limitation, the filing of any financing or
continuation statements under the Uniform Commercial Code in effect in any
jurisdiction with respect to the Liens created hereby. The Borrower also
hereby authorizes the Administrative Agent to file any such financing or
continuation statement without the signature of the Borrower to the extent
permitted by applicable law. A carbon, photographic or other reproduction of
this Security Agreement shall be sufficient as a financing statement for
filing in any jurisdiction. If any amount payable under or in connection with
any of the Collateral shall be or become evidenced by any Instrument or
Chattel Paper, such Instrument or Chattel Paper shall be immediately
delivered to the Administrative Agent, duly endorsed in a manner satisfactory
to the Administrative Agent, to be held as Collateral pursuant to this
Security Agreement.

                  (b) INDEMNIFICATION. The Borrower agrees to pay, and to
save the Administrative Agent and the Lenders harmless from, any and all
liabilities, costs and expenses (including, without limitation, legal fees
and expenses) (i) with respect to, or resulting from, any delay in paying any
and all excise, sales or other taxes which may be payable or determined to be
payable with respect to any of the Collateral, (ii) with respect to, or
resulting from, any delay in complying with any Requirement of Law applicable
to any of the Collateral or (iii) in connection with any of the transactions
contemplated by this Security Agreement, except resulting from the
Administrative Agent's or any Lender's gross negligence or willful
misconduct. In any suit, proceeding or action brought by the Administrative
Agent or any Lender under any Account or Contract for any sum owing
thereunder, or to enforce any provisions of any Account or Contract, the
Borrower will save, indemnify and keep the Administrative Agent and such
Lender harmless from and against all expense, loss or damage suffered by
reason of any defense, setoff, counterclaim, recoupment or reduction or
liability whatsoever of the account debtor or obligor thereunder, arising out
of a breach by the Borrower of any obligation thereunder or arising out of
any other agreement, indebtedness or liability at any time owing to or in
favor of such account debtor or obligor or its successors from the Borrower,
except resulting from the Administrative Agent's or any Lender's gross
negligence or willful misconduct.

                  (c) MAINTENANCE OF RECORDS. The Borrower will keep and
maintain at its own cost and expense satisfactory and complete records of the
Collateral, including, without limitation, a record of all payments received
and all credits granted with respect to the Accounts. The Borrower will mark
its books and records pertaining to the Collateral to evidence this Security
Agreement and the security interests granted hereby in such manner as the
Administrative Agent may request. For the Administrative Agent's and the
Lenders' further security, the Administrative Agent, for the ratable benefit
of the Lenders, shall have a security interest in all the Borrower's books
and records pertaining to the Collateral, and the Borrower shall, during the
continuance of a Default under Section 7.1(a) of the Credit Agreement or
Section 7.1(c) of the Credit Agreement as it relates to Section 6.1 of the
Credit Agreement, turn over copies of such books and records and during the
continuation of an Event of Default turn over any such books and records, in
each case, to the Administrative Agent or to its representatives at the
request of the Administrative Agent.

                  (d) RIGHT OF INSPECTION. The Administrative Agent and the
Lenders shall at all times have full and free access during normal business
hours and, so long as no Event of Default shall have occurred and be
continuing, upon reasonable prior notice, to all books, correspondence and
records of the Borrower, and the Administrative Agent and the Lenders and
their respective representatives may examine the same, take extracts
therefrom and make photocopies thereof, and the Borrower agrees to render to
the Administrative Agent and the Lenders, at the Borrower's cost and expense,
such clerical and other assistance as may be reasonably requested with regard
thereto. The Administrative Agent and the Lenders and their respective
representatives shall at all times and, so long as no Event of Default shall
have occurred and be continuing, upon reasonable prior notice, also have the
right to enter into and upon any premises where any of the Inventory or
Equipment is located for the purpose of inspecting the same, observing its
use or otherwise protecting its interests therein.

                  (e) COMPLIANCE WITH LAWS. The Borrower will comply in all
material respects with all Requirements of Law applicable to the Collateral
or any part thereof or to the operation


                                      -8-

<PAGE>

of the Borrower's business; PROVIDED that the Borrower may contest any
Requirement of Law in any reasonable manner which shall not, in the sole
opinion of the Administrative Agent, adversely affect the Administrative
Agent's or the Lenders' rights or the priority of their Liens on the
Collateral.

                  (f) COMPLIANCE WITH TERMS OF CONTRACTS. The Borrower will
perform and comply in all material respects with all its obligations under
the Contracts and all its other Contractual Obligations relating to the
Collateral.

                  (g) PAYMENT OF OBLIGATIONS. The Borrower will pay promptly
when due all taxes, assessments and governmental charges or levies imposed
upon the Collateral or in respect of its income or profits therefrom, as well
as all claims of any kind (including, without limitation, claims for labor,
materials and supplies) against or with respect to the Collateral, except
that no such charge need be paid if (i) the validity thereof is being
contested in good faith by appropriate proceedings, (ii) such proceedings do
not involve any material danger of the sale, forfeiture or loss of any of the
Collateral or any interest therein and (iii) such charge is adequately
reserved against on the Borrower's books in accordance with GAAP.

                  (h) LIMITATION ON LIENS ON COLLATERAL. The Borrower will
not create, incur or permit to exist, will defend the Collateral against, and
will take such other action as is necessary to remove, any Lien or claim on
or to the Collateral, other than the Liens created hereby and other than as
permitted pursuant to Section 6.3 of the Credit Agreement, and will defend
the right, title and interest of the Administrative Agent and the Lenders in
and to any of the Collateral against the claims and demands of all Persons
whomsoever.

                  (i) LIMITATIONS ON DISPOSITIONS OF COLLATERAL. The Borrower
will not sell, transfer, lease or otherwise dispose of any of the Collateral,
or attempt, offer or contract to do so except as permitted pursuant to
Section 6.6 of the Credit Agreement.

                  (j) LIMITATIONS ON MODIFICATIONS, WAIVERS, EXTENSIONS OF
CONTRACTS AND AGREEMENTS GIVING RISE TO ACCOUNTS. Subject to subsection (k)
below, the Borrower will not (i) amend, modify, terminate or waive any
provision of any Material Contract or any agreement giving rise to an Account
in any manner which could reasonably be expected to materially adversely
affect the value of such Contract or Account as Collateral, (ii) fail to
exercise promptly and diligently each and every material right which it may
have under each Contract and each agreement giving rise to an Account (other
than any right of termination) or (iii) fail to deliver to the Administrative
Agent a copy of each material demand, notice or document received by it
relating in any way to any Contract or any agreement giving rise to an
Account. As used in this clause (j), a "Material Contract" shall mean (x) any
purchase order or license agreement by Fluent, Inc. with a value of more than
$750,000 in any 12-month period or (y) any other contract with a stated
duration (including any extension periods contained therein) of more than 12
months and with a value of more than $750,000.

                  (k) LIMITATIONS ON DISCOUNTS, COMPROMISES, EXTENSIONS OF
ACCOUNTS. Other than in the ordinary course of business, the Borrower will
not grant any extension of the time of payment of any of the Accounts,
compromise, compound or settle the same for less than the full


                                      -9-

<PAGE>

amount thereof, release, wholly or partially, any Person liable for the
payment thereof, or allow any credit or discount whatsoever thereon.

                  (l) MAINTENANCE OF EQUIPMENT. The Borrower will maintain
each item of Equipment not subject to Section 6.6(a) of the Credit Agreement
in good operating condition, ordinary wear and tear and immaterial
impairments of value and damage by the elements excepted, and will provide
all maintenance, service and repairs necessary for such purpose.

                  (m) MAINTENANCE OF INSURANCE. The Borrower will maintain,
with financially sound and reputable companies, insurance policies as
required under the Credit Agreement. All such policies shall (i) contain a
breach of warranty clause in favor of the Administrative Agent and the
Lenders, (ii) provide that no cancellation, material reduction in amount or
material change in coverage thereof shall be effective until at least 30 days
after receipt by the Administrative Agent and the Lenders of written notice
thereof, (iii) name the Administrative Agent as loss payee of each such
policy, (iv) name the Administrative Agent and the Lenders as insured to the
extent of their interests under each such policy and (v) be reasonably
satisfactory in all material respects to the Administrative Agent. The
Borrower shall deliver to the Administrative Agent and each Lender upon
request, full information as to the insurance carried, including certified
copies of policies and certificates of insurance from a recognized insurance
broker reasonably acceptable to the Administrative Agent.

                  (n) FURTHER IDENTIFICATION OF COLLATERAL. The Borrower will
furnish to the Administrative Agent and the Lenders from time to time
statements and schedules further identifying and describing the Collateral
and such other reports in connection with the Collateral as the
Administrative Agent may reasonably request, all in reasonable detail.

                  (o) NOTICES. The Borrower will advise the Administrative
Agent promptly, in reasonable detail, at its address set forth in the Credit
Agreement, (i) of any Lien (other than Liens created hereby or permitted
under the Credit Agreement) on, or claim asserted against, any of the
Collateral and (ii) of the occurrence of any other event which could
reasonably be expected to have a material adverse effect on the aggregate
value of the Collateral or on the Liens created hereunder.

                  (p) CHANGES IN LOCATIONS, NAME, ETC. Unless the Borrower
gives 30 days' prior written notice to the Administrative Agent, the Borrower
will not (i) change the location of its chief executive office/chief place of
business from that specified in Section 4(f) or remove its books and records
from the location specified in Section 4(c), (ii) permit any of the Inventory
or Equipment to be kept at a location other than those listed on Schedule I
hereto or (iii) change its name, identity or corporate structure to such an
extent that any financing statement filed by the Administrative Agent in
connection with this Security Agreement would become seriously misleading.

                  6.  ADMINISTRATIVE AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT.

                  (a) POWERS. The Borrower hereby irrevocably constitutes and
appoints the Administrative Agent and any officer or agent thereof, with full
power of substitution, as its true and lawful attorney-in-fact with full
irrevocable power and authority in the place and stead of the


                                      -10-

<PAGE>

Borrower and in the name of the Borrower or in its own name, from time to
time in the Administrative Agent's discretion, for the purpose of carrying
out the terms of this Security Agreement, to take any and all appropriate
action and to execute any and all documents and instruments which may be
necessary or desirable to accomplish the purposes of this Security Agreement,
and, without limiting the generality of the foregoing, the Borrower hereby
gives the Administrative Agent the power and right, on behalf of the
Borrower, without notice to or assent by the Borrower, to do the following:

                  (i)   in the case of any Account, at any time when the
                        authority of the Borrower to collect the Accounts has
                        been curtailed or terminated pursuant to the first
                        sentence of Section 3(c), or in the case of any
                        other Collateral, at any time when any Event of Default
                        shall have occurred and is continuing, in the name of
                        the Borrower or its own name, or otherwise, to take
                        possession of and endorse and collect any checks,
                        drafts, notes, acceptances or other instruments for
                        the payment of moneys due under any Account, Instrument,
                        General Intangible or Contract or with respect to any
                        other Collateral and to file any claim or to take any
                        other action or proceeding in any court of law or equity
                        or otherwise deemed appropriate by the Administrative
                        Agent for the purpose of collecting any and all such
                        moneys due under any Account, Instrument, General
                        Intangible or Contract or with respect to any other
                        Collateral whenever payable;

                  (ii)  to pay or discharge taxes and Liens levied or placed on
                        or threatened against the Collateral, to effect any
                        repairs or any insurance called for by the terms of
                        this Security Agreement and to pay all or any part
                        of the premiums therefor and the costs thereof; and

                        Event of Default, (A) to direct any party liable for
                        any payment under any of the Collateral to make
                        payment of any and all moneys due or to become due
                        thereunder directly to the Administrative Agent or as
                        the Administrative Agent shall direct; (B) to ask or
                        demand for, collect, receive payment of and receipt
                        for, any and all moneys, claims and other amounts due
                        or to become due at any time in respect of or arising
                        out of any Collateral; (C) to sign and endorse any

                        commence and prosecute any suits, actions or proceedings

                        and to enforce any other right in respect of any
                        Collateral; (E) to defend any suit, action or proceeding
                        brought against the Borrower with respect to any
                        Collateral; (F) to settle, compromise or adjust any
                        suit, action or proceeding described in clause (E) above

                        pledge and make any agreement with respect to or
                        otherwise deal with any of the Collateral as fully and
                        completely as though the Administrative Agent


                                      -11-

<PAGE>

                        were the absolute owner thereof for all purposes, and
                        to do, at the Administrative Agent's option and the
                        Borrower's expense, at any time, or from time to time,
                        all acts and things which the Administrative Agent
                        deems necessary to protect, preserve or realize upon
                        the Collateral and the Administrative Agent's and the
                        Lenders' Liens thereon and to effect the intent of this
                        Security Agreement, all as fully and effectively as the
                        Borrower  might do.

The Borrower 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 shall be irrevocable.

                  (b) OTHER POWERS. The Borrower also authorizes the
Administrative Agent and the Lenders, at any time and from time to time, to
execute, in connection with the sale provided for in this SECTION 6 or in
SECTION 9 hereof, any endorsements, assignments or other instruments of
conveyance or transfer with respect to the Collateral.

                  (c) NO DUTY ON ADMINISTRATIVE AGENT OR LENDERS' PART. The
powers conferred on the Administrative Agent and the Lenders hereunder are
solely to protect the Administrative Agent's and the Lenders' interests in
the Collateral and shall not impose any duty upon the Administrative Agent or
any Lender to exercise any such powers. The Administrative Agent and the
Lenders shall be accountable only for amounts that they actually receive as a
result of the exercise of such powers, and neither they nor any of their
officers, directors, employees or agents shall be responsible to the Borrower
for any act or failure to act hereunder, except for their own gross
negligence or willful misconduct.

                  7. PERFORMANCE BY ADMINISTRATIVE AGENT OF BORROWER'S
OBLIGATIONS. If the Borrower fails to perform or comply with any of its
agreements contained herein and the Administrative Agent, as provided for by
the terms of this Security Agreement, shall itself perform or comply, or
otherwise cause performance or compliance, with such agreement, the expenses
of the Administrative Agent incurred in connection with such performance or
compliance, together with interest thereon at a rate per annum 2% above the
Alternate Base Rate, shall be payable by the Borrower to the Administrative
Agent on demand and shall constitute Obligations secured hereby.

                  8. PROCEEDS. In addition to the rights of the
Administrative Agent and the Lenders specified in Section 3(c) with respect
to payments of Accounts, it is agreed that if an Event of Default shall occur
and be continuing (a) upon written notice by the Administrative Agent to the
Borrower, all Proceeds received by the Borrower consisting of cash, checks
and other near-cash items shall be held by the Borrower in trust for the
Administrative Agent and the Lenders, segregated from other funds of the
Borrower, and, forthwith upon receipt by the Borrower, shall be turned over
to the Administrative Agent in the exact form received by the Borrower (duly
endorsed by the Borrower to the Administrative Agent, if required), and (b)
any and all such Proceeds received by the Administrative Agent (whether from
the Borrower or otherwise) may, in the sole discretion of the Administrative
Agent, (i) be held by the Administrative Agent for the ratable benefit of the
Lenders as collateral security for the Obligations, and/or (ii) then or at
any time thereafter either (x) be applied by the Administrative


                                      -12-


<PAGE>

Agent for the ratable benefit of the Lenders against the Obligations (whether
matured or unmatured), such application to be in such order as the
Administrative Agent shall elect, or (y) at the sole discretion of the
Administrative Agent, be available for use by the Borrower in the operation
of its business. Any balance of such Proceeds remaining after the Obligations
shall have been paid in full and the Commitments shall have been terminated
shall be paid over to the Borrower or to whomsoever may be lawfully entitled
to receive the same.

                  9. REMEDIES. If an Event of Default shall occur and be
continuing, the Administrative Agent, on behalf of the Lenders, may exercise,
in addition to all other rights and remedies granted to them in this Security
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Obligations, all rights and remedies of a secured party under
the Code. Without limiting the generality of the foregoing, the
Administrative Agent, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law referred to below) to or upon the Borrower, any guarantor, or
any other Person (all and each of which demands, defenses, advertisements and
notices being hereby waived to the maximum extent permitted by applicable
law), may in such circumstances forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and/or may forthwith sell,
lease, assign, give option or options to purchase, or otherwise dispose of
and deliver the Collateral or any part thereof (or contract to do any of the
foregoing), in one or more parcels at public or private sale or sales, at any
exchange, broker's board or office of the Administrative Agent or any Lender
or elsewhere upon such terms and conditions as it may deem advisable and at
such prices as it may deem best, for cash or on credit or for future delivery
without assumption of any credit risk. The Administrative Agent or any Lender
shall have the right upon any such public sale or sales, and, to the extent
permitted by applicable law, upon any such private sale or sales, to purchase
the whole or any part of the Collateral so sold, free of any right or equity
of redemption in the Borrower, which right or equity is hereby waived or
released to the maximum extent permitted by applicable law. The Borrower
further agrees, at the Administrative Agent's request, to assemble the
Collateral and make it available to the Administrative Agent at such places
as the Administrative Agent shall reasonably select, whether at the
Borrower's premises or elsewhere. The Administrative Agent shall apply the
net proceeds of any such collection, recovery, receipt, appropriation,
realization or sale, after deducting all reasonable costs and expenses of
every kind incurred therein or incidental to the care or safekeeping of any
of the Collateral or in any way relating to the Collateral or the rights of
the Administrative Agent and the Lenders hereunder, including, without
limitation, reasonable attorneys' fees and disbursements, to the payment in
whole or in part of the Obligations, in such order as the Administrative
Agent may elect, and only after such application and after the payment by the
Administrative Agent of any other amount required by any provision of law,
including, without limitation, Section 9-504(i)(c) of the Code, need the
Administrative Agent account for the surplus, if any, to the Borrower. To the
extent permitted by applicable law, the Borrower waives all claims, damages
and demands it may acquire against the Administrative Agent or any Lender
arising out of the exercise by them of any rights hereunder. If any notice of
a proposed sale or other disposition of Collateral shall be required by law,
such notice shall be deemed reasonable and proper if given at least 10 days
before such sale or other disposition. The Borrower shall remain liable for
any deficiency if the proceeds of any sale or other disposition of the
Collateral are insufficient to pay the Obligations and the fees and
disbursements of any attorneys employed by the Administrative Agent or any
Lender to collect such deficiency.

<PAGE>

                  10. LIMITATION ON DUTIES REGARDING PRESERVATION OF
COLLATERAL. The Administrative Agent's sole duty with respect to the custody,
safekeeping and physical preservation of the Collateral in its possession,
under Section 9-207 of the Code or otherwise, shall be to deal with it in the
same manner as the Administrative Agent deals with similar property for its
own account. Neither the Administrative Agent, any Lender, nor any of their
respective directors, officers, employees or agents shall be liable for
failure to demand, collect or realize upon all or any part of the Collateral
or for any delay in doing so or shall be under any obligation to sell or
otherwise dispose of any Collateral upon the request of the Borrower or
otherwise.

                  11. POWERS COUPLED WITH AN INTEREST. All authorizations and
agencies herein contained with respect to the Collateral are irrevocable and
powers coupled with an interest.

                  12. LIMITATION ON LINES OF BUSINESS. Nothing in this
Security Agreement shall be deemed or construed as modifying in any way the
restrictions on the Borrower's activities as set forth in Section 6.14 of the
Credit Agreement.

                  13. SEVERABILITY. Any provision of this Security Agreement
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and
any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction.

                  14. SECTION HEADINGS. The section headings used in this
Security Agreement are for convenience of reference only and are not to
affect the construction hereof or be taken into consideration in the
interpretation hereof.

                  15. NO WAIVER; CUMULATIVE REMEDIES. Neither the
Administrative Agent nor any Lender shall by any act (except by a written
instrument pursuant to SECTION 16), delay, indulgence, omission or otherwise
be deemed to have waived any right or remedy hereunder or to have acquiesced
in any Default or Event of Default or in any breach of any of the terms and
conditions hereof. No failure to exercise, nor any delay in exercising, on
the part of the Administrative Agent or any Lender, any right, power or
privilege hereunder shall operate as a waiver thereof. No single or partial
exercise of any right, power or privilege hereunder shall preclude any other
or further exercise thereof or the exercise of any other right, power or
privilege. A waiver by the Administrative Agent or any Lender of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Administrative Agent or such Lender would otherwise
have on any future occasion. The rights and remedies herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of
any rights or remedies provided by law.

                  16. WAIVERS AND AMENDMENTS; SUCCESSORS AND ASSIGNS. None of
the terms or provisions of this Security Agreement may be waived, amended,
supplemented or otherwise modified except by a written instrument executed by
the Borrower and the Administrative Agent; PROVIDED that any provision of
this Security Agreement may be waived by the Administrative Agent in a
written letter or agreement executed by the Administrative Agent or by telex
or facsimile transmission from the Administrative Agent. This Security
Agreement


                                      -14-

<PAGE>

shall be binding upon the successors and assigns of the Borrower and shall
inure to the benefit of the Administrative Agent and the Lenders and their
respective successors and assigns.

                  17. GOVERNING LAW. THIS SECURITY AGREEMENT AND THE RIGHTS
AND OBLIGATIONS OF THE PARTIES UNDER THIS SECURITY AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE
STATE OF NEW YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS
THEREOF OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE STATE
OF NEW YORK, EXCEPT FOR PERFECTION AND ENFORCEMENT OF SECURITY INTERESTS AND
LIENS IN OTHER JURISDICTIONS TO THE EXTENT THE LAW OF ANOTHER JURISDICTION IS
MANDATORILY APPLICABLE PURSUANT TO THE LAWS OF SUCH JURISDICTION.

                  18. NOTICES. Notices hereunder may be given by mail, by
telex or by facsimile transmission, addressed or transmitted to the Person to
which it is being given at such Person's address or transmission number set
forth in the Credit Agreement and shall be effective (a) in the case of mail,
three days after deposit in the postal system, first class postage pre-paid
and (b) in the case of telex or facsimile notices, when sent if receipt is
confirmed by telephone. The Borrower may change its address and transmission
number by written notice to the Administrative Agent, and the Administrative
Agent or any Lender may change its address and transmission number by written
notice to the Borrower and, in the case of any Lender, to the Administrative
Agent.

                  19. AUTHORITY OF ADMINISTRATIVE AGENT. The Borrower
acknowledges that the rights and responsibilities of the Administrative Agent
under this Security Agreement with respect to any action taken by the
Administrative Agent or the exercise or non-exercise by the Administrative
Agent of any option, right, request, judgment or other right or remedy
provided for herein or resulting or arising out of this Security Agreement
shall, as between the Administrative Agent and the Lenders, be governed by
the Credit Agreement and by such other agreements with respect thereto as may
exist from time to time among them, but, as between the Administrative Agent
and the Borrower, the Administrative Agent shall be conclusively presumed to
be acting as agent for the Lenders with full and valid authority so to act or
refrain from acting, and the Borrower shall not be under any obligation, or
entitlement, to make any inquiry respecting such authority.

                  20. COUNTERPARTS. This Security Agreement may be executed
in counterparts, and all of such counterparts taken together shall be deemed
to constitute one and the same instrument.

                  (a) If the Pledgor, as a result of its ownership of the
         Pledged Stock, shall become entitled to receive or shall receive any
         Capital Stock certificates or other securities of any issuer of Pledged
         Stock (including, without limitation, any certificate representing a
         distribution of Capital Stock in connection with any reclassification,
         increase or reduction of capital or any certificate issued in
         connection with any reorganization), option or rights, whether in
         addition to, in substitution of, as a conversion of, or in exchange for
         any of the Pledged Stock, or otherwise in respect thereof, the Pledgor
         shall accept the same as the agent of the Administrative Agent and the
         Lenders, hold the same in trust for the benefit of the Administrative
         Agent and the Lenders and deliver the same forthwith to the
         Administrative Agent in the exact form received, duly endorsed by the
         Pledgor to the Administrative Agent, if required, together with an
         undated power covering such certificate duly executed in blank by the
         Pledgor to be held by the Administrative Agent, subject to the terms
         hereof, as additional collateral security for the Obligations. Any sums
         paid upon or in respect of the Pledged Stock upon the liquidation or
         dissolution of any issuer of Pledged Stock and any distribution of
         capital in respect of the Pledged Stock or any cash pursuant to the
         recapitalization or reclassification of the capital of any issuer of
         Pledged Stock or pursuant to the reorganization thereof shall, within
         15 days after receipt thereof by the Administrative Agent and in the
         sole discretion of the Administrative Agent, either be (i) applied in
         payment of the Obligations in such order as the Administrative Agent
         may elect or (ii) paid over to the Pledgor for its use in the operation
         of its business, and in case any distribution of capital shall be made
         on or in respect of the Pledged Stock or any property shall be
         distributed upon or with respect to the Pledged Stock pursuant to the
         recapitalization or reclassification of the capital of any issuer of
         Pledged Stock or pursuant to the reorganization thereof, the property
         so distributed shall be delivered to the Administrative Agent to be
         held by it hereunder as additional collateral security for the
         Obligations. If any sums of money or property so paid or distributed in
         respect of the Pledged Stock shall be received by the Pledgor, the
         Pledgor shall, until such money or property is paid or delivered to the
         Administrative Agent, hold such money or property in


                                      4


<PAGE>


         trust for the benefit of the Lenders, segregated from other funds of
         the Pledgor, as additional collateral security for the Obligations.

                  (b) If the Pledgor shall become entitled to receive or shall
         have received any Pledged Debt, the Pledgor shall accept the same as
         the agent of the Administrative Agent and the Lenders, hold the same in
         trust for the Administrative Agent and the Lenders and deliver the same
         forthwith to the Administrative Agent in the exact form received,
         together with an undated endorsement covering such Pledged Debt duly
         executed in blank by the Pledgor, to be held by the Administrative
         Agent, subject to the terms hereof, as additional collateral security
         for the Guarantee Obligations. Any sums paid upon or in respect of any
         Pledged Debt upon the bankruptcy, liquidation or dissolution of any of
         the makers of any such Pledged Debt shall be paid over to the
         Administrative Agent to be held by it hereunder as additional
         collateral security for the Guarantee Obligations and shall within 15
         days after receipt thereof by the Administrative Agent and in the sole
         discretion of the Administrative Agent, either be (i) applied in
         payment of the Obligations in such order as the Administrative Agent
         may elect or (ii) paid over to the Pledgor for its use in the operation
         of its business. If any sums of money or property so paid in respect of
         any such Pledged Debt shall be received by the Pledgor, the Pledgor
         shall, until such money or property is paid or delivered to the
         Administrative Agent, hold such money or property in trust for the
         Administrative Agent and Lenders, segregated from other funds of the
         Pledgor, as additional collateral security for the Guarantee
         Obligations.

                  (c) Without the prior written consent of the Administrative
         Agent, the Pledgor will not (i) vote to enable, or take any other
         action to permit, any issuer of Pledged Stock to issue Capital Stock or
         other equity securities of any nature or to issue any other securities
         convertible into or granting the right to purchase or exchange for any
         Capital Stock or other equity securities of any nature of any issuer of
         Pledged Stock (other than any Capital Stock or other equity securities
         constituting Management Shares), (ii) sell, assign, transfer, exchange,
         or otherwise dispose of, or grant any option with respect to, the
         Collateral, or (iii) create, incur or permit to exist any other Lien or
         option in favor of, or any claim of any Person with respect to, any of
         the Collateral, or any interest therein, except for the Lien provided
         for by this Pledge Agreement. The Pledgor will defend and will
         indemnify and hold harmless the Administrative Agent and the Lenders
         against the claims and demands of all Persons whomsoever with respect
         to any claim arising from or in connection with the right, title and
         interest of the Administrative Agent and the Lenders in and to the
         Collateral.

                  (d) At any time and from time to time, upon the written
         request of the Administrative Agent, and at the sole expense of the
         Pledgor, the Pledgor will promptly and duly execute and deliver such
         further instruments and documents and take such further actions as the
         Administrative Agent may reasonably request for the purposes of
         obtaining or preserving the full benefits of this Pledge Agreement and
         of the rights and powers herein granted. If any amount payable under or
         in connection with any of the Collateral shall be or become evidenced
         by any promissory note, other instrument or chattel paper, such note,
         instrument or chattel paper shall be immediately delivered to the
         Administrative Agent, duly endorsed in a manner satisfactory to the
         Administrative Agent, to be held as Collateral pursuant to this Pledge
         Agreement.

                  (e) The Pledgor agrees to pay, and to save the Administrative
         Agent and the Lenders harmless from, any and all liabilities with
         respect to, or resulting from any delay in paying, any and all stamps,
         excise, sales or other taxes which may be payable or determined to be
         payable with respect to any of the Collateral or in connection with any
         of the transactions contemplated by this Pledge Agreement.

                  (f) The Pledgor agrees that, within 30 days of any
         corporation, limited liability company or similar entity becoming a
         Subsidiary (as defined in the Credit Agreement), in the case of shares
         of Capital Stock of such Subsidiary represented by one or more
         certificates, it shall (i) upon the request of the Administrative
         Agent, deliver to the Administrative Agent all such shares (or, in the
         case of any Foreign Subsidiary, 65% of such shares) owned by the
         Pledgor, together with, in each case, appropriate undated powers duly
         executed in blank and (ii) execute and deliver a new pledge agreement
         (or a supplement to this Pledge Agreement) covering such shares. Upon
         such delivery, such shares shall constitute a representation and
         warranty as of the date of such delivery that the representations and
         warranties contained in SECTION 4 above are true and correct on such
         date after giving effect to such delivery. The Pledgor shall also
         furnish to the Lenders such legal opinions confirming such
         representations and warranties as the Administrative Agent or any
         Lender may reasonably request.

                  6. CASH DIVIDENDS; VOTING RIGHTS. Unless a Default or Event
of Default shall have occurred and be continuing, the Pledgor shall be
permitted to receive all cash dividends, distributions, interest and
principal paid on the Pledged Securities to the extent that such cash
dividends, distributions, interest and principal are permitted in the Credit
Agreement and applicable laws; PROVIDED that any such cash dividends,
distributions, interest or principal received by the Pledgor during the
pendency of any Default (but prior to the occurrence of an Event of Default)
shall be returned promptly to the issuer of such cash dividends,
distributions, interest or principal, and any such cash dividends,
distributions, interest or principal received during the pendency of any
Default but not returned prior to such Default becoming an Event of Default
or during the pendency of any Event of Default shall be delivered promptly to
the Administrative Agent. Unless an Event of Default shall have occurred and
be continuing, the Pledgor shall be permitted to exercise all voting and
corporate rights with respect to the Pledged Stock; PROVIDED that no vote
shall be cast or corporate right exercised or other action taken which, in
the Administrative Agent's reasonable judgment, would impair the Collateral
or which would be inconsistent with or result in any violation of any
provision of the Credit Agreement, the Notes, the other Loan Documents or
this Pledge Agreement.

                  7. RIGHTS OF THE LENDERS AND THE ADMINISTRATIVE AGENT. (a)
If an Event of Default shall occur and be continuing, (i) the Administrative
Agent shall have the right to receive any and all dividends, distributions,
interest and principal paid in respect of the Pledged Securities, and to make
application thereof to the Obligations in such order as the Administrative
Agent may determine and (ii) all of the Pledged Stock shall be registered in
the name of the Administrative Agent or its nominee, and the Administrative
Agent or its nominee may thereafter exercise (A) all voting, corporate and
other rights pertaining to the Pledged Stock, and (B) any and all rights of
conversion, exchange, subscription and any other rights, privileges or
options, pertaining to any of the Pledged Stock as if it were the absolute
owner thereof (including, without limitation, the right to exchange at its
discretion any and all the Pledged


                                      6


<PAGE>


Stock upon the merger, consolidation, reorganization, recapitalization or
other fundamental change in the corporate structure of any issuer of Pledged
Stock, or upon the exercise by the Pledgor or the Administrative Agent of any
right, privilege or option pertaining to any of the Pledged Stock, and in
connection therewith, the right to deposit and deliver any and all of the
Pledged Stock with any committee, depositary, transfer agent, registrar or
other designated agency upon such terms and conditions as it may determine),
all without liability to the Administrative Agent except to account for
property actually received by it, but the Administrative Agent shall have no
duty to the Pledgor to exercise any such right, privilege or option and shall
not be responsible for any failure to do so or delay in so doing.

                  (b) The rights of the Administrative Agent and the Lenders
hereunder shall not be conditioned or contingent upon the pursuit by the
Administrative Agent or any Lender of any right or remedy against the
Pledgor, any issuer of Pledged Stock, any guarantor or against any other
Person which may be or become liable in respect of all or any part of the
Obligations or against any collateral security therefor, guarantee therefor
or right of offset with respect thereto. Neither the Administrative Agent nor
any Lender shall be liable for any failure to demand, collect or realize upon
all or any part of the Collateral or for any delay in doing so, nor shall the
Administrative Agent be under any obligation to sell or otherwise dispose of
any Collateral upon the request of the Pledgor or any other Person or to take
any other action whatsoever with regard to the Collateral or any part thereof.

                  8. REMEDIES. If an Event of Default shall occur and be
continuing, the Administrative Agent, on behalf of the Lenders, may exercise,
in addition to all other rights and remedies granted in this Pledge Agreement
and in any other instrument or agreement securing, evidencing or relating to
the Obligations, all rights and remedies of a secured party under the Code.
Without limiting the generality of the foregoing, the Administrative Agent,
without demand of performance or other demand, presentment, protest,
advertisement or notice of any kind (except any notice required by law
referred to below) to or upon the Pledgor, any issuer of Pledged Stock, any
guarantor or any other Person (all and each of which demands, defenses,
advertisements and notices are hereby waived to the maximum extent permitted
by law), may in such circumstances forthwith collect, receive, appropriate
and realize upon the Collateral, or any part thereof, and/or may forthwith
sell, assign, give option or options to purchase or otherwise dispose of and
deliver the Collateral or any part thereof (or contract to do any of the
foregoing), in one or more parcels at public or private sale or sales, in the
over-the-counter market, at any exchange, broker's board or office of the
Administrative Agent or any Lender or elsewhere upon such terms and
conditions as it may deem advisable and at such prices as it may deem best,
for cash or on credit or for future delivery without assumption of any credit
risk. The Administrative Agent or any Lender shall have the right upon any
such public sale or sales, and, to the extent permitted by law, upon any such
private sale or sales, to purchase the whole or any part of the Collateral so
sold free of any right or equity of redemption in the Pledgor, which right or
equity is hereby waived or released to the maximum extent permitted by law.
The Administrative Agent shall apply any Proceeds from time to time held by
it and the net proceeds of any such collection, recovery, receipt,
appropriation, realization or sale, after deducting all reasonable costs and
expenses of every kind incurred in respect thereof or incidental to the care
or safekeeping of any of the Collateral or in any way relating to the
Collateral or the rights of the Administrative Agent and the Lenders
hereunder, including, without limitation, attorneys' fees and disbursements
of counsel to the Administrative Agent, to the payment in whole or in part of


                                      7


<PAGE>


the Obligations, in such order as the Administrative Agent may elect, and
only after such application and after the payment by the Administrative Agent
of any other amount required by any provision of law, including, without
limitation, Section 9-504(1)(c) of the Code, need the Administrative Agent
account for the surplus, if any, to the Pledgor. To the extent permitted by
applicable law, the Pledgor waives all claims, damages and demands it may
acquire against the Administrative Agent or any Lender arising out of the
exercise by them of any rights hereunder. If any notice of a proposed sale or
other disposition of Collateral shall be required by law, such notice shall
be deemed reasonable and proper if given at least 10 days before such sale or
other disposition. The Pledgor shall remain liable for any deficiency if the
proceeds of any sale or other disposition of Collateral are insufficient to
pay the Obligations and the fees and disbursements of any attorneys employed
by the Administrative Agent or any Lender to collect such deficiency.

                  9. PRIVATE SALES. (a) The Pledgor recognizes that the
Administrative Agent may be unable to effect a public sale of any or all the
Pledged Securities, by reason of certain prohibitions contained in the
Securities Act of 1933 (the "SECURITIES ACT") and applicable state securities
laws or otherwise, and may be compelled to resort to one or more private
sales thereof to a restricted group of purchasers which will be obliged to
agree, among other things, to acquire such securities for their own account
for investment and not with a view to the distribution or resale thereof. The
Pledgor acknowledges and agrees that any such private sale may result in
prices and other terms less favorable than if such sale were a public sale
and, notwithstanding such circumstances, agrees that any such private sale
shall be deemed to have been made in a commercially reasonable manner. The
Administrative Agent shall be under no obligation to delay a sale of any of
the Pledged Securities for the period of time necessary to permit any issuer
of Pledged Stock or the Pledgor to register such securities for public sale
under the Securities Act, or under applicable state securities laws, even if
such issuer or the Pledgor would agree to do so.

                  (b) The Pledgor further agrees to use its best efforts to
do or cause to be done all such other acts as may be necessary to make such
sale or sales of all or any portion of the Pledged Securities pursuant to
this SECTION 9 valid and binding and in compliance with any and all other
applicable Requirements of Law. The Pledgor further agrees that a breach of
any of the covenants contained in this SECTION 9 will cause irreparable
injury to the Administrative Agent and the Lenders, that the Administrative
Agent and the Lenders have no adequate remedy at law in respect of such
breach and, as a consequence, that each and every covenant contained in this
SECTION 9 shall be specifically enforceable against the Pledgor, and the
Pledgor hereby waives and agrees not to assert any defenses against an action
for specific performance of such covenants except for a defense that no Event
of Default has occurred under the Credit Agreement.

                  10. LIMITATION ON DUTIES REGARDING COLLATERAL. The
Administrative Agent's sole duty with respect to the custody, safekeeping and
physical preservation of the Collateral in its possession, under Section
9-207 of the Code or otherwise, shall be to deal with it in the same manner
as the Administrative Agent deals with similar securities and property for
its own account. None of the Administrative Agent, the Lenders or any of
their respective directors, officers, employees or agents shall be liable for
failure to demand, collect or realize upon any of


                                      8


<PAGE>


the Collateral or for any delay in doing so or shall be under any obligation
to sell or otherwise dispose of any Collateral upon the request of the
Pledgor or otherwise.

                  11. POWERS COUPLED WITH AN INTEREST. All authorizations and
agencies herein contained with respect to the Collateral are irrevocable and
powers coupled with an interest.

                  12. SEVERABILITY. Any provision of this Pledge Agreement
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and
any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction.

                  13. SECTION HEADINGS. The section headings used in this
Pledge Agreement are for convenience of reference only and are not to affect
the construction hereof or be taken into consideration in the interpretation
hereof.

                  14. NO WAIVER; CUMULATIVE REMEDIES. Neither the
Administrative Agent nor any Lender shall by any act (except by a written
instrument pursuant to SECTION 15) be deemed to have waived any right or
remedy hereunder or to have acquiesced in any Default or Event of Default or
in any breach of any of the terms and conditions hereof. No failure to
exercise, nor any delay in exercising, on the part of the Administrative
Agent or any Lender, any right, power or privilege hereunder shall operate as
a waiver thereof. No single or partial exercise of any right, power or
privilege hereunder shall preclude any other or further exercise thereof or
the exercise of any other right, power or privilege. A waiver by the
Administrative Agent or any Lender of any right or remedy hereunder on any
one occasion shall not be construed as a bar to any right or remedy which the
Administrative Agent or such Lender would otherwise have on any future
occasion. The rights and remedies herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

                  15. WAIVERS AND AMENDMENTS; SUCCESSORS AND ASSIGNS;
GOVERNING LAW. None of the terms or provisions of this Pledge Agreement may
be amended, supplemented or otherwise modified except by a written instrument
executed by the Pledgor and the Administrative Agent; PROVIDED that any
provision of this Pledge Agreement may be waived by the Administrative Agent
in a letter or agreement executed by the Administrative Agent or by telex or
facsimile transmission from the Administrative Agent. This Pledge Agreement
shall inure to the benefit of the Administrative Agent and the Lenders and
their respective successors and assigns. THIS PLEDGE AGREEMENT AND THE RIGHTS
AND OBLIGATIONS OF THE PARTIES UNDER THIS PLEDGE AGREEMENT SHALL BE GOVERNED
BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE
OF NEW YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS THEREOF
OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW
YORK.

                  16. NOTICES. Notices may be given by mail, by telex or by
facsimile transmission, addressed or transmitted to the Person to which it is
being given at such Person's address or transmission number set forth in the
Credit Agreement and shall be effective (a) in the case of mail, three days
after deposit in the postal system, first class postage pre-paid, and (b) in


                                      9


<PAGE>


the case of telex or facsimile notices, when sent if receipt is confirmed by
telephone. The Pledgor and any issuer of Pledged Stock may change their
respective addresses and transmission numbers by written notice to the
Administrative Agent.

                  17. IRREVOCABLE AUTHORIZATION AND INSTRUCTION TO ISSUERS.
The Pledgor hereby authorizes and instructs each issuer of Pledged Stock to
comply with any instruction received by it from the Administrative Agent in
writing that (a) states that an Event of Default has occurred and (b) is
otherwise in accordance with the terms of this Pledge Agreement, without any
other or further instructions from the Pledgor, and the Pledgor agrees that
such issuer shall be fully protected in so complying.

                  18. AUTHORITY OF AGENT. The Pledgor acknowledges that the
rights and responsibilities of the Administrative Agent under this Pledge
Agreement with respect to any action taken by the Administrative Agent or the
exercise or non-exercise by the Administrative Agent of any option, voting
right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Pledge Agreement shall, as between the
Administrative Agent and the Lenders, be governed by the Credit Agreement and
by such other agreements with respect thereto as may exist from time to time
among them, but, as between the Administrative Agent and the Pledgor, the
Administrative Agent shall be conclusively presumed to be acting as agent for
the Lenders with full and valid authority so to act or refrain from acting,
and neither the Pledgor nor any issuer of Pledged Stock shall be under any
obligation, or entitlement, to make any inquiry respecting such authority.

                  19. TERMINATION; RELEASE. Upon the repayment of all the
Obligations in full and the termination of the Commitments, this Pledge
Agreement shall terminate, and the Administrative Agent, at the request of
and sole expense of the Pledgor, will execute and deliver to the Pledgor the
proper instruments (including Uniform Commercial Code termination statements
on form UCC-2 or UCC-3, as applicable) acknowledging the termination of this
Pledge Agreement, and will duly assign, transfer and deliver to the Pledgor
(without recourse and without any representation or warranty of any kind)
such of the Collateral as may be in the possession of the Administrative
Agent and has not theretofore been disposed of or otherwise applied or
released.

                  20. COUNTERPARTS. This Pledge Agreement may be executed in
counterparts, and all of such counterparts taken together shall be deemed to
constitute one and the same instrument.

                           FORM CONTRIBUTION AGREEMENT

into as of October 21, 1999 among (i) Aavid Thermal Technologies of Texas LLC,
a Delaware limited liability company (successor by merger to Aavid Thermal

Inc., a Delaware corporation (successor by merger to Aavid Thermal Products,
Inc., a New Hampshire corporation) (each a "SUBSIDIARY" and, collectively,
the "SUBSIDIARIES").

                              W I T N E S S E T H :

                  WHEREAS, Aavid Thermal Technologies, Inc., a Delaware
corporation (the "BORROWER"), has entered into the Amended and Restated
Credit Agreement dated as of February 2, 2000, among the Borrower, Heat
Holdings Corp., Heat Holdings II Corp., the several banks and other financial
institutions (the "LENDERS") from time to time party thereto, Canadian
Imperial Bank of Commerce, as issuer of certain letters of credit, Canadian
Imperial Bank of Commerce, as administrative agent for the Lenders (the
"ADMINISTRATIVE AGENT"), BankBoston, N.A. as documentation agent (the
"DOCUMENTATION AGENT") and CIBC World Markets Corp., as lead arranger and
bookrunner (as the same may hereafter be amended, supplemented or otherwise
modified from time to time, the "CREDIT AGREEMENT"; terms used therein being
used as therein defined);

                  WHEREAS, in connection therewith, each Subsidiary has
entered into a Guarantee dated as of the date hereof in favor of the
Administrative Agent for the benefit of the Lenders, pursuant to which such
Subsidiary has guaranteed all the Obligations of the Borrower (such
Guarantees, as the same may be amended, supplemented or modified from time to
time, are collectively referred to as the "SUBSIDIARY GUARANTEES"); and

                  WHEREAS, the Borrower, the Parent and Holding II,
collectively own, directly or indirectly, all the Capital Stock of each of
the Subsidiaries, and each of the Subsidiaries derives substantial benefit
from the Borrower entering into the Credit Agreement and obtaining Loans
thereunder;


<PAGE>


                  NOW, THEREFORE, in consideration of the premises and the
covenants hereafter contained, and to induce each of the Subsidiaries to
enter into its respective Subsidiary Guarantee, it is agreed as follows:

                  The parties agree as among themselves that, to the extent
any payment of the Obligations of the Borrower is required to be made under a
Subsidiary Guarantee, each Subsidiary shall be responsible for a portion of
such payment equal to the product of (a) a fraction, the numerator of which
is the net worth (determined in accordance with U.S. GAAP) of such Subsidiary
on the date the Indebtedness which is the subject of such payment was
incurred and the denominator of which is the aggregate net worth (computed as
aforesaid) of the Subsidiaries (such fraction is referred to in the case of
any Subsidiary as its "NET WORTH FRACTION"), MULTIPLIED BY (b) the amount of
such payment (such product being such Subsidiary's "CONTRIBUTION AMOUNT"). To
the extent that any Subsidiary (the "PAYING SUBSIDIARY") shall make a payment
in respect of the Obligations of the Borrower under its Subsidiary Guarantee
in excess of its Contribution Amount, each of the other Subsidiaries shall
reimburse the Paying Subsidiary in an amount equal to the product of (x) such
other Subsidiary's Net Worth Fraction multiplied by (y) such excess.

                  This Agreement is only intended to define the relative
rights of the Subsidiaries, and nothing set forth in this Agreement is
intended to or shall impair the obligations of the Subsidiaries, jointly and
severally, to pay to the Agents and the Lenders the Obligations as and when
the same shall become due and payable in accordance with the terms of their
respective Subsidiary Guarantees.

                  The parties hereto acknowledge that the right to
contribution hereunder shall constitute an asset in favor of the Subsidiaries
to which such contribution is owing.

                  The parties hereto acknowledge and agree that the
Administrative Agent, for the benefit of the Lenders and the Issuer, is an
intended third-party beneficiary of this Agreement and that until the
indefeasible payment of all the Obligations and the termination of the
Commitments, this Agreement may not be terminated, amended or modified in a
manner that would adversely affect either Agent or the Lenders without the
prior written consent of the Administrative Agent.

                  The parties hereto acknowledge and agree that this
Agreement has been entered into so as to support the arrangement set forth in
the Credit Agreement which is governed by the laws of the State of New York.
The parties hereto desire that this Agreement be interpreted in a manner
consistent with the interpretation of the Credit Agreement and to that end
have agreed that this Agreement will be governed by and construed in
accordance with the laws of the State of New York and in such selection have
relied, among other items, upon Section 5-1401 of the General Obligations Law
of the State of New York.

Lenders to make their respective Loans to the Borrower and the Issuer to issue

                  NOW, THEREFORE, in consideration of the premises and to induce
the Lenders to enter into the Credit Agreement and to make the Loans to the
Borrower under the Credit Agreement, the Guarantor hereby agrees with and for

                  1. DEFINED TERMS. As used in this Guarantee, terms defined in
the Credit Agreement are used herein as therein defined, and the following term

                  "OBLIGATIONS" shall mean the unpaid principal of and interest

Loans and interest accruing after the filing of any petition in bankruptcy, or
the commencement of any insolvency, reorganization or like proceeding, relating
to the Parent, the Guarantor, the Borrower or any of their respective
Subsidiaries, as applicable, whether or not a claim for post-filing or
post-petition interest is allowed in such proceeding and whether the
Administrative Agent, for the benefit of the Lenders, is oversecured or
undersecured with respect to such Loans) the Notes and all other obligations and
liabilities of the Parent, Guarantor, the Borrower or any such Subsidiary, as
applicable, to the Agents and the Lenders or any of their respective Affiliates,
including any Reimbursement Obligations and any obligation of the Borrower under
any Hedging Agreement entered into with any Agent, any Lender or any of their
respective Affiliates, whether direct or indirect, absolute or contingent, due
or to become due, now existing or hereafter incurred, which may arise under, out
of, or in connection with, the Credit Agreement, the Notes, the other Loan
Documents or any Hedging Agreement with any Agent, any Lender or any of their
respective Affiliates or any other document made, delivered or given in
connection therewith or herewith, whether on account of principal, interest,
reimbursement obligations, fees, indemnities, costs, expenses (including,
without limitation, all fees and disbursements of counsel to any Agent or to the
Lenders that are required to be paid by the Parent, Guarantor, the Borrower or
any Subsidiary, as applicable, pursuant to the terms of the Credit Agreement,

any of their respective Affiliates) or otherwise.

                  2. GUARANTEE. (a) The Guarantor hereby unconditionally and
irrevocably guarantees to the Administrative Agent and the Lenders and their
respective successors, endorsees, transferees and assigns, the prompt and
complete payment by the Borrower when due (whether at the stated maturity, by
acceleration or otherwise) of the Obligations, and the Guarantor further agrees
to pay any and all expenses (including, without limitation, all fees and
disbursements of counsel) which may be paid or incurred by the Administrative
Agent or any Lender in enforcing, or obtaining advice of counsel in respect of,
any rights with respect to, or collecting, any or all the Obligations and/or
enforcing any rights with respect to, or collecting against, the Guarantor under
this Guarantee.


                                       2
<PAGE>


                                (b) No payment or payments made by the Borrower,
any other guarantor or any other Person or received or collected by the
Administrative Agent or any Lender from the Borrower, any other guarantor or any
other Person by virtue of any action or proceeding or any setoff or
appropriation or application at any time or from time to time in reduction of or
in payment of the Obligations shall be deemed to modify, reduce, release or
otherwise affect the liability of the Guarantor hereunder which shall,
notwithstanding any such payment or payments other than payments made by the
Guarantor in respect of the Obligations or payments received or collected from
the Guarantor in respect of the Obligations, remain liable for the Obligations
until the Obligations are paid in full and the Commitments are terminated.

                                (c) The Guarantor agrees that whenever, at any
time, or from time to time, it shall make any payment to the Administrative
Agent or any Lender on account of its liability hereunder, it will notify the
Administrative Agent in writing that such payment is made under this Guarantee
for such purpose.

                  3. RIGHT OF SETOFF. Upon the occurrence of any Event of
Default specified in the Credit Agreement, the Guarantor hereby irrevocably
authorizes the Administrative Agent and each Lender at any time and from time to
time without notice to the Guarantor or any other guarantor, any such notice
being expressly waived by the Guarantor, to setoff and appropriate and apply any
and all deposits (general or special, time or demand, provisional or final), in
any currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by the Administrative Agent and/or such
Lender to or for the credit or the account of the Guarantor, or any part thereof
in such amounts as the Administrative Agent or such may elect, against and on
account of the obligations and liabilities of the Guarantor to the
Administrative Agent or such Lender hereunder and claims of every nature and
description of the Administrative Agent or such Lender against the Guarantor, in
any currency, whether arising hereunder, under the Credit Agreement, the Notes,
the Security Documents, any other Loan Document, any Hedging Agreement with
either Agent, any Lender or any of their respective Affiliates or otherwise, as
the Administrative Agent or such Lender may elect, whether or not the
Administrative Agent or any Lender has made any demand for payment and although
such obligations, liabilities and claims may be contingent or unmatured. The
Administrative Agent and each Lender agrees to notify the Guarantor promptly of
any such setoff and the application made by the Administrative Agent or such
Lender; PROVIDED that the failure to give such notice shall not affect the
validity of such setoff and application. The rights of the Administrative Agent
and each Lender under this paragraph are in addition to other rights and
remedies (including, without limitation, other rights of setoff) which the
Administrative Agent or such Lender may have.

                  4. NO SUBROGATION. Notwithstanding any payment or payments
made by the Guarantor hereunder or any setoff or application of funds of the
Guarantor by the Administrative Agent or any Lender, until all Obligations have
been irrevocably and indefeasibly paid in full in cash (and therefore the
payment thereof is no longer subject to being set aside or returned under
applicable law), the Guarantor hereby waives any claim, right or remedy which
the Guarantor may now have or may hereafter acquire against the Borrower that
arises hereunder and/or from the performance by the Guarantor hereunder
including, without limitation, any claim, remedy or right of subrogation,
reimbursement, exoneration, contribution, indemnification or participation in
any claim, right or remedy of the Lenders and the Administrative Agent against
the Borrower


                                       3
<PAGE>


or any security which the Lenders and the Administrative Agent now have or
hereafter acquire, whether or not such claim, right or remedy arises in
equity, under contract, by statute, under common law or otherwise; PROVIDED
that if the foregoing standstill is not sufficient to permit indefeasible
payment in full of all the Obligations, then the Guarantor shall be deemed to
have waived any such claim, right or remedy to the maximum extent permitted
by law. If any amount shall be paid to the Guarantor on account of such
subrogation rights at any time when all the Obligations shall not have been
paid in full, such amount shall be held by the Guarantor in trust for the
Administrative Agent and the Lenders, segregated from other funds of the
Guarantor, and shall, forthwith upon receipt by the Guarantor, be turned over
to the Administrative Agent in the exact form received by the Guarantor (duly
endorsed by the Guarantor to the Administrative Agent, if required), to be
applied against the Obligations, whether matured or unmatured, in such order
as the Administrative Agent may determine.

                  5. AMENDMENTS, ETC, WITH RESPECT TO THE OBLIGATIONS: WAIVER
OF RIGHTS. The Guarantor shall remain obligated hereunder notwithstanding
that, without any reservation of rights against the Guarantor and without
notice to or further assent by the Guarantor, any demand for payment of any
of the Obligations made by the Administrative Agent or any Lender may be
rescinded by such party and any of the Obligations continued, and the
Obligations, or the liability of any other party upon or for any part
thereof, or any collateral security or guarantee therefor or right of offset
with respect thereto, may, from time to time, in whole or in part, be
renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released, in accordance with the terms of such agreement, by
the Administrative Agent or any Lender and the Credit Agreement, the Notes,
the Security Documents, the other Loan Documents, any Hedging Agreement with
either Agent or Lender and any other collateral security document or other
guarantee or document in connection therewith may be amended, modified,
supplemented or terminated, in whole or in part, in accordance with the terms
of such agreement, as the Administrative Agent and/or any Lender may deem
advisable from time to time, and any collateral security, guarantee or right
of offset at any time held by the Administrative Agent or any Lender for the
payment of the Obligations may be sold, exchanged, waived, surrendered or
released. Neither the Administrative Agent nor any Lender shall have any
obligation to protect, secure, perfect or insure any Lien at any time held as
security for the Obligations or for this Guarantee or any property subject
thereto. When making any demand hereunder against the Guarantor, the
Administrative Agent or any Lender may, but shall be under no obligation to,
make a similar demand on the Borrower or any other guarantor, and any failure
by the Administrative Agent or any Lender to make any such demand or to
collect any payments from the Borrower or any such other guarantor or any
release of the Borrower or such other guarantor shall not relieve the
Guarantor of its obligations or liabilities hereunder, and shall not impair
or affect the rights and remedies, express or implied, or as a matter of law,
of the Administrative Agent against the Guarantor. For the purposes hereof,
"demand" shall include the commencement and continuance of any legal
proceedings.

                  6. GUARANTEE ABSOLUTE AND UNCONDITIONAL. The Guarantor waives
any and all notice of the creation, renewal, extension or accrual of any of the
Obligations and notice of or proof of reliance by the Administrative Agent or
any Lender upon this Guarantee or acceptance of this Guarantee, the Obligations,
and any of them, shall conclusively be deemed to have been created, contracted
or incurred, or renewed, extended, amended or waived, in reliance upon this
Guarantee; and all dealings between the Borrower or the Guarantor and the
Administrative


                                       4
<PAGE>


Agent or any Lender shall likewise be conclusively presumed to
have been had or consummated in reliance upon this Guarantee. The Guarantor
waives diligence, presentment, protest, demand for payment and notice of default
or nonpayment to or upon the Borrower or the Guarantor with respect to the
Obligations. The Guarantor understands and agrees that this Guarantee shall be
construed as a continuing, absolute and unconditional guarantee of payment
without regard to (a) the validity, regularity or enforceability of the Credit
Agreement, the Notes, any of the Security Documents, any other Loan Document,
any of the obligations or any other collateral security therefor or guarantee or
right of offset with respect thereto at any time or from time to time held by
the Administrative Agent or any Lender, (b) any defense, setoff or counterclaim
(other than a defense of payment or performance) which may at any time be
available to or be asserted by the Borrower against Administrative Agent or any
Lender, or (c) any other circumstance whatsoever (with or without notice to or
knowledge of the Borrower or the Guarantor) which constitutes, or might be
construed to constitute, an equitable or legal discharge of the Borrower for the
Obligations, or of the Guarantor under this Guarantee, in bankruptcy or in any
other instance. When pursuing its rights and remedies hereunder against the
Guarantor, the Administrative Agent and any Lender may, but shall be under no
obligation to, pursue such rights and remedies as it may have against the
Borrower or any other Person or against any collateral security or guarantee for
the obligations or any right of offset with respect thereto, and any failure by
the Administrative Agent or any Lender to pursue such other rights or remedies
or to collect any payments from the Borrower or any such other Person or to
realize upon any such collateral security or guarantee or to exercise any such
right of offset, or any release of the Borrower or any such other Person or any
such collateral security, guarantee or right of offset, shall not relieve the
Guarantor of any liability hereunder, and shall not impair or affect the rights
and remedies, whether express, implied or available as a matter of law, of the
Administrative Agent or any Lender against the Guarantor. This Guarantee shall
remain in full force and effect and be binding in accordance with and to the
extent of its terms upon the Guarantor and the successors and assigns thereof,
and shall inure to the benefit of the Administrative Agent and the Lenders, and
its respective successors, endorsees, transferees and assigns, until all the
Obligations and the obligations of the Guarantor under this Guarantee shall have
been satisfied by payment in full and the Commitments shall be terminated,
notwithstanding that from time to time during the term of the Credit Agreement
the Borrower may be free from any Obligations.

                  7. REINSTATEMENT. This Guarantee shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any of the Obligations is rescinded or must otherwise be
restored or returned by the Administrative Agent or any Lender upon the
insolvency, bankruptcy, dissolution, liquidation or reorganization of the
Borrower or the Guarantor, or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
Borrower or the Guarantor or any substantial part of its property, or otherwise,
all as though such payments had not been made.

                  8. PAYMENTS. The Guarantor hereby guarantees that payments
hereunder will be paid to the Administrative Agent for the benefit or the
Lenders without setoff or counterclaim in U.S. Dollars at the office of the
Administrative Agent located at 425 Lexington Avenue, New York, New York 10017
or such other location as the Administrative Agent may from time to time direct
the Guarantor.

                  9. REPRESENTATIONS AND WARRANTIES. The Guarantor hereby
represents and warrants that:

                                (a)       the Guarantor has the corporate power
and authority, and the legal right, to execute, deliver and perform its
obligations under, this Guarantee and the other Loan Documents to which the
Guarantor is a party, and has taken all necessary corporate action to authorize
the execution, delivery and performance of this Guarantee and the other Loan
Documents to which the Guarantor is a party;

                                (b)       this Guarantee and the other Loan
Documents to which the Guarantor is a party each constitute a legal, valid and
binding obligation of the Guarantor enforceable in accordance with its terms,
except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditors, rights generally or by general principles of equity (whether
enforcement is sought by proceedings in equity or at law);

                                (c)      the execution, delivery and performance
by the Guarantor of this Guarantee or any other Loan Document to which the
Guarantor is a party will not violate any Requirement of Law or Contractual
Obligation of the Guarantor, and will not result in, or require, the creation or
imposition of any Lien on any of the properties or revenues of the Guarantor
pursuant to any such Requirement of Law or Contractual Obligation except Liens
created pursuant to the Loan Documents; and

                                (d)      no consent or authorization of, filing
with or other act by or in respect of, any Governmental Authority or any other
Person (including, without limitation, any stockholder or creditor of the
Guarantor) is required in connection with the execution, delivery, performance,
validity or enforceability of this Guarantee or any other Loan Document to which
the Guarantor is a party.

                  The Guarantor agrees that the foregoing representations and
warranties shall be deemed to have been made by the Guarantor on the date of
each borrowing by the Borrower under the Credit Agreement on and as of such date
of borrowing as though made hereunder on and as of such date.

                  10. SEVERABILITY. (a) Any provision of this Guarantee which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                                (b)      The parties hereto have agreed as
provided in SECTION 13 of this Guarantee and in the Credit Agreement, that New
York law is to govern, among other matters, the amount of interest that may
lawfully be charged, received or contracted for in connection with the
Obligations. If, notwithstanding such agreement, a court of competent
jurisdiction applies the law of any other jurisdiction to such interest, then
the following shall apply:

                  It is expressly stipulated and agreed to be the intent of the
Guarantor and the Administrative Agent at all times to comply with applicable
state law governing the maximum


                                       6
<PAGE>


rate or amount of interest payable with respect to the Obligations (or
applicable United States federal law to the extent that it permits the
Administrative Agent to contract for, charge, take, reserve or receive a
greater amount of interest than under state law, including, without
limitation, 12 U.S.C. Section 85 (1994)). If the applicable law is ever
judicially interpreted so as to render usurious any amount called for under
the Obligations or under this Guarantee, or contracted for, charged, taken,
reserved or received with respect to the Obligations, then it is the
Guarantor's and the Administrative Agent's express intent that all excess
amounts theretofore collected by the Administrative Agent be credited on the
principal balance of the Obligations (or, if the Obligations have been or
would thereby be paid in full, refunded to the Guarantor), and the provisions
of this Guarantee and all other documents immediately be deemed reformed and
the amounts thereafter collectible hereunder and thereunder reduced, without
the necessity of the execution of any new documents, so as to comply with the
applicable law, but so as to permit the recovery of the fullest amount
otherwise called for hereunder or thereunder.

                  11. SECTION HEADINGS. The section headings used in this
Guarantee are for convenience of reference only and are not to affect the
construction hereof or be taken into consideration in the interpretation hereof.

                  12. NO WAIVER: CUMULATIVE REMEDIES. Neither the Administrative
Agent nor any Lender shall by any act (except by a written instrument pursuant
to SECTION 13), delay, indulgence, omission or otherwise be deemed to have
waived any right or remedy hereunder or to have acquiesced in any Default or
Event of Default or in any breach of any of the terms and conditions hereof. No
failure to exercise, nor any delay in exercising, on the part of the
Administrative Agent or any Lender, any right, power or privilege hereunder
shall operate as a waiver thereof. No single or partial exercise of any right,
power or privilege hereunder shall preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. A waiver by the
Administrative Agent or any Lender of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy which the
Administrative Agent or such Lender would otherwise have on any future occasion.
The rights and remedies herein provided are cumulative, may be exercised singly
or concurrently and are not exclusive of any rights or remedies provided by law.

                  13. INTEGRATION; WAIVERS AND AMENDMENTS; SUCCESSORS AND
ASSIGNS; GOVERNING LAW. This Guarantee represents the agreement of the Guarantor
with respect to the subject matter hereof and there are no promises or
representations by the Administrative Agent or any Lender relative to the
subject matter hereof not reflected herein. None of the terms or provisions of
this Guarantee may be waived, amended or supplemented or otherwise modified
except by a written instrument executed by the Guarantor and the Administrative
Agent; provided that any provision of this Guarantee may be waived by the
Administrative Agent and the Lenders in a letter or agreement executed by the
Administrative Agent or by telex or facsimile transmission from the
Administrative Agent. This Guarantee shall be binding upon the successors and
assigns of the Guarantor and shall inure to the benefit of the Administrative
Agent and their and their respective successors and assigns. THIS GUARANTEE AND
THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS GUARANTEE SHALL BE GOVERNED
BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
YORK WITHOUT REGARD TO THE PRINCIPLES OF


                                       7
<PAGE>

         the Pledgor, except as enforceability may be limited by bankruptcy,
         insolvency, reorganization, moratorium or similar laws affecting the
         enforcement of creditors' rights generally and by general equitable
         principles (whether enforcement is sought by proceedings in equity or
         at law); and

                  (e) The chief executive office of the Pledgor and the office
         where the Pledgor keeps its records concerning all contracts is located
         at c/o Willis Stein & Partners, 227 West Monroe Street, Suite 4300,
         Chicago, IL 60606. The Pledgor shall not establish a new location for
         its chief executive office or change its name until (i) it has given to

         its intention to do so, clearly describing such new location or
         specifying such new name, as the case may be, and (ii) with respect to
         such new location or such new name, as the case may be, it shall have
         taken all action, satisfactory to the Administrative Agent, necessary
         to maintain the security interest of the Administrative Agent in the
         Collateral intended to be granted hereby at all times fully perfected
         and in full force and effect.

                  5. COVENANTS. The Pledgor covenants and agrees with the
Administrative Agent and the Lenders that, from and after the date of this
Pledge Agreement until the Obligations are paid in full and the Commitments are

         Pledged Stock, shall become entitled to receive or shall receive any
         Capital Stock certificates of any issuer of Pledged Stock (including,
         without limitation, any certificate representing a distribution of
         Capital Stock in connection with any reclassification, increase or
         reduction of capital or any certificate issued in connection with any
         reorganization), option or rights, whether in addition to, in
         substitution of, as a conversion of, or in exchange for any of the
         Pledged Stock, or otherwise in respect thereof, the Pledgor shall
         accept the same as the agent of the Administrative Agent and the
         Lenders, hold the same in trust for the benefit of the Administrative
         Agent and the Lenders and deliver the same forthwith to the
         Administrative Agent in the exact form received, duly endorsed by the
         Pledgor to the Administrative Agent, if required, together with an
         undated power covering such certificate duly executed in blank by the
         Pledgor to be held by the Administrative Agent, subject to the terms
         hereof, as additional collateral security for the Guarantee
         Obligations. Any sums paid upon or in respect of the Pledged Stock upon
         the liquidation or dissolution of any issuer of Pledged Stock and any
         distribution of capital in respect of the Pledged Stock or any cash
         pursuant to the recapitalization or reclassification of the capital of
         any

                                       4

<PAGE>

         issuer of Pledged Stock or pursuant to the reorganization thereof
         shall, within 15 days after receipt thereof by the Administrative Agent
         and in the sole discretion of the Administrative Agent, either be (i)
         applied in payment of the Obligations in such order as the
         Administrative Agent may elect or (ii) paid over to the Pledgor for its
         use in the operation of its business, and in case any distribution of
         capital shall be made on or in respect of the Pledged Stock or any
         property shall be distributed upon or with respect to the Pledged Stock
         pursuant to the recapitalization or reclassification of the capital of
         any issuer of Pledged Stock or pursuant to the reorganization thereof,
         the property so distributed shall be delivered to the Administrative
         Agent to be held by it hereunder as additional collateral security for
         the Guarantee Obligations. If any sums of money or property so paid or
         distributed in respect of the Pledged Stock shall be received by the
         Pledgor, the Pledgor shall, until such money or property is paid or
         delivered to the Administrative Agent, hold such money or property in
         trust for the benefit of the Lenders, segregated from other funds of
         the Pledgor, as additional collateral security for the Guarantee
         Obligations.

                  (b) Without the prior written consent of the Administrative
         Agent, the Pledgor will not (i) vote to enable, or take any other
         action to permit, any issuer of Pledged Stock to issue Capital Stock or
         other equity securities of any nature or to issue any other securities
         convertible into or granting the right to purchase or exchange for any
         Capital Stock or other equity securities of any nature of any issuer of
         Pledged Stock (other than any Capital Stock or other equity securities
         constituting Management Shares), (ii) sell, assign, transfer, exchange,
         or otherwise dispose of, or grant any option with respect to, the
         Collateral, or (iii) create, incur or permit to exist any other Lien or
         option in favor of, or any claim of any Person with respect to, any of
         the Collateral, or any interest therein, except for the Lien provided
         for by this Pledge Agreement. The Pledgor will defend and will
         indemnify and hold harmless the Administrative Agent and the Lenders
         against the claims and demands of all Persons whomsoever with respect
         to any claim arising from or in connection with the right, title and
         interest of the Administrative Agent and the Lenders in and to the
         Collateral.

                  (c) At any time and from time to time, upon the written
         request of the Administrative Agent, and at the sole expense of the
         Pledgor, the Pledgor will promptly and duly execute and deliver such
         further instruments and documents and take such further actions as the
         Administrative Agent may reasonably request for the purposes of
         obtaining or preserving the full benefits of this Pledge Agreement and
         of the rights and powers herein granted. If any amount payable under or
         in connection with any of the Collateral shall be or become evidenced
         by any promissory note, other instrument or chattel paper, such note,
         instrument or chattel paper shall be immediately delivered to the
         Administrative Agent, duly endorsed in a manner satisfactory to the
         Administrative Agent, to be held as Collateral pursuant to this Pledge
         Agreement.

                  (d) The Pledgor agrees to pay, and to save the Administrative
         Agent and the Lenders harmless from, any and all liabilities with
         respect to, or resulting from any delay in paying, any and all stamps,
         excise, sales or other taxes which may be payable or determined to be
         payable with respect to any of the Collateral or in connection with any
         of the transactions contemplated by this Pledge Agreement.

                  (e) The Pledgor agrees that, within 30 days of any
         corporation, limited liability company or similar entity becoming a
         Subsidiary (as defined in the Credit Agreement), in the case of units
         of Capital Stock of such Subsidiary represented by one or more
         certificates, it shall (i) upon the request of the Administrative
         Agent, deliver to the Administrative Agent all such units (or, in the
         case of any Foreign Subsidiary, 65% of such units) owned by the
         Pledgor, together with, in each case, appropriate undated

                                       5

<PAGE>

         powers duly executed in blank and (ii) execute and deliver a new pledge
         agreement (or a supplement to this Pledge Agreement) covering such
         units. Upon such delivery, such units shall constitute a representation
         and warranty as of the date of such delivery that the representations
         and warranties contained in SECTION 4 above are true and correct on
         such date after giving effect to such delivery. The Pledgor shall also
         furnish to the Lenders such legal opinions confirming such
         representations and warranties as the Administrative Agent or any
         Lender may reasonably request.

                  6.       CASH DISTRIBUTIONS; VOTING RIGHTS.

                  Unless a Default or Event of Default shall have occurred and
be continuing, the Pledgor shall be permitted to receive all cash dividends,
distributions, interest and principal paid on the Pledged Stock to the extent
that such cash dividends, distributions, interest and principal are permitted in
the Credit Agreement and applicable laws; PROVIDED that any such cash dividends,
distributions, interest or principal received by the Pledgor during the pendency
of any Default (but prior to the occurrence of an Event of Default) shall be
returned promptly to the issuer of such cash dividends, distributions, interest
or principal, and any such cash dividends, distributions, interest or principal
received during the pendency of any Default but not returned prior to such
Default becoming an Event of Default or during the pendency of any Event of
Default shall be delivered promptly to the Administrative Agent. Unless an Event
of Default shall have occurred and be continuing, the Pledgor shall be permitted
to exercise all voting and limited liability company rights with respect to the
Pledged Stock; PROVIDED that no vote shall be cast or limited liability company
right exercised or other action taken which, in the Administrative Agent's
reasonable judgment, would impair the Collateral or which would be inconsistent
with or result in any violation of any provision of the Credit Agreement, the
Notes, the other Loan Documents or this Pledge Agreement.

                  7. RIGHTS OF THE LENDERS AND THE ADMINISTRATIVE AGENT. (a) If
an Event of Default shall occur and be continuing, (i) the Administrative Agent
shall have the right to receive any and all dividends, distributions, interest
and principal paid in respect of the Pledged Stock, and to make application
thereof to the Obligations in such order as the Administrative Agent may
determine and (ii) all of the Pledged Stock shall be registered in the name of
the Administrative Agent or its nominee, and the Administrative Agent or its
nominee may thereafter exercise (A) all voting, limited liability company and
other rights pertaining to the Pledged Stock, and (B) any and all rights of
conversion, exchange, subscription and any other rights, privileges or options,
pertaining to any of the Pledged Stock as if it were the absolute owner thereof
(including, without limitation, the right to exchange at its discretion any and
all the Pledged Stock upon the merger, consolidation, reorganization,
recapitalization or other fundamental change in the corporate structure of any
issuer of Pledged Stock, or upon the exercise by the Pledgor or the
Administrative Agent of any right, privilege or option pertaining to any of the
Pledged Stock, and in connection therewith, the right to deposit and deliver any
and all of the Pledged Stock with any committee, depositary, transfer agent,
registrar or other designated agency upon such terms and conditions as it may
determine), all without liability to the Administrative Agent except to account
for property actually received by it, but the Administrative Agent shall have no
duty to the Pledgor to exercise any such right, privilege or option and shall
not be responsible for any failure to do so or delay in so doing.

                  (b) The rights of the Administrative Agent and the Lenders
hereunder shall not be conditioned or contingent upon the pursuit by the
Administrative Agent or any Lender of any right or remedy against the Pledgor,
any issuer of Pledged Stock, any guarantor or against any other Person which may
be or become liable in respect of all or any part of the Obligations or against
any collateral security therefor, guarantee therefor or right of offset with
respect thereto. Neither the Administrative Agent nor any Lender shall be liable
for any failure to demand, collect or realize upon all or any part of the
Collateral or for any delay in doing so, nor shall the Administrative Agent be
under any obligation to sell or otherwise dispose of any Collateral upon the
request of the Pledgor or any other Person or to take any other action
whatsoever with regard to the Collateral or any part thereof.

                  8. REMEDIES. If an Event of Default shall occur and be
continuing, the Administrative Agent, on behalf of the Lenders, may exercise, in
addition to all other rights and remedies granted in this Pledge Agreement and
in any other instrument or agreement securing, evidencing or relating to the
Obligations, all rights and remedies of a secured party under the Code. Without
limiting the generality of the foregoing, the Administrative Agent, without
demand of performance or other demand, presentment, protest, advertisement or
notice of any kind (except any notice required by law referred to below) to or
upon the Pledgor, any issuer of Pledged Stock, any guarantor or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby
waived to the maximum extent permitted by law), may in such circumstances
forthwith collect, receive, appropriate and realize upon the Collateral, or any
part thereof, and/or may forthwith sell, assign, give option or options to
purchase or otherwise dispose of and deliver the Collateral or any part thereof
(or contract to do any of the foregoing), in one or more parcels at public or
private sale or sales, in the over-the-counter market, at any exchange, broker's
board or office of the Administrative Agent or any Lender or elsewhere upon such
terms and conditions as it may deem advisable and at such prices as it may deem
best, for cash or on credit or for future delivery without assumption of any
credit risk. The Administrative Agent or any Lender shall have the right upon
any such public sale or sales, and, to the extent permitted by law, upon any
such private sale or sales, to purchase the whole or any part of the Collateral
so sold free of any right or equity of redemption in the Pledgor, which right or
equity is hereby waived or released to the maximum extent permitted by law. The
Administrative Agent shall apply any Proceeds from time to time held by it and
the net proceeds of any such collection, recovery, receipt, appropriation,
realization or sale, after deducting all reasonable costs and expenses of every
kind incurred in respect thereof or incidental to the care or safekeeping of any
of the Collateral or in any way relating to the Collateral or the rights of the
Administrative Agent and the Lenders hereunder, including, without limitation,
attorneys' fees and disbursements of counsel to the Administrative Agent, to the
payment in whole or in part of the Obligations, in such order as the
Administrative Agent may elect, and only after such application and after the
payment by the Administrative Agent of any other amount required by any
provision of law, including, without limitation, Section 9-504(1)(c) of the
Code, need the Administrative Agent account for the surplus, if any, to the
Pledgor. To the extent permitted by applicable law, the Pledgor waives all
claims, damages and demands it may acquire against the Administrative Agent or
any Lender arising out of the exercise by them of any rights hereunder. If any
notice of a proposed sale or other disposition of Collateral shall be required
by law, such notice shall be deemed reasonable and proper if given at least 10
days before such sale or other disposition. The Pledgor shall remain liable for
any deficiency if the proceeds of any sale or other disposition of Collateral
are insufficient to pay the Obligations and the fees and

                                       7

<PAGE>

disbursements of any attorneys employed by the Administrative Agent or any
Lender to collect such deficiency.

                  9. PRIVATE SALES. (a) The Pledgor recognizes that the
Administrative Agent may be unable to effect a public sale of any or all the
Pledged Stock, by reason of certain prohibitions contained in the Securities Act
of 1933 (the "SECURITIES ACT") and applicable state securities laws or
otherwise, and may be compelled to resort to one or more private sales thereof
to a restricted group of purchasers which will be obliged to agree, among other
things, to acquire such securities for their own account for investment and not
with a view to the distribution or resale thereof. The Pledgor acknowledges and
agrees that any such private sale may result in prices and other terms less
favorable than if such sale were a public sale and, notwithstanding such
circumstances, agrees that any such private sale shall be deemed to have been
made in a commercially reasonable manner. The Administrative Agent shall be
under no obligation to delay a sale of any of the Pledged Stock for the period
of time necessary to permit any issuer of Pledged Stock or the Pledgor to
register such securities for public sale under the Securities Act, or under
applicable state securities laws, even if such issuer or the Pledgor would agree
to do so.

                  (b) The Pledgor further agrees to use its best efforts to do
or cause to be done all such other acts as may be necessary to make such sale or
sales of all or any portion of the Pledged Stock pursuant to this SECTION 9
valid and binding and in compliance with any and all other applicable
Requirements of Law. The Pledgor further agrees that a breach of any of the
covenants contained in this SECTION 9 will cause irreparable injury to the
Administrative Agent and the Lenders, that the Administrative Agent and the
Lenders have no adequate remedy at law in respect of such breach and, as a
consequence, that each and every covenant contained in this SECTION 9 shall be
specifically enforceable against the Pledgor, and the Pledgor hereby waives and
agrees not to assert any defenses against an action for specific performance of
such covenants except for a defense that no Event of Default has occurred under
the Credit Agreement.

                  10. LIMITATION ON DUTIES REGARDING COLLATERAL. The
Administrative Agent's sole duty with respect to the custody, safekeeping and
physical preservation of the Collateral in its possession, under Section 9-207
of the Code or otherwise, shall be to deal with it in the same manner as the
Administrative Agent deals with similar securities and property for its own
account. None of the Administrative Agent, the Lenders or any of their
respective directors, officers, employees or agents shall be liable for failure
to demand, collect or realize upon any of the Collateral or for any delay in
doing so or shall be under any obligation to sell or otherwise dispose of any
Collateral upon the request of the Pledgor or otherwise.

                  11. POWERS COUPLED WITH AN INTEREST. All authorizations and
agencies herein contained with respect to the Collateral are irrevocable and
powers coupled with an interest.

                  12. SEVERABILITY. Any provision of this Pledge Agreement which
is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

                  13. SECTION HEADINGS. The section headings used in this Pledge
Agreement are for convenience of reference only and are not to affect the
construction hereof or be taken into consideration in the interpretation hereof.

                  14. NO WAIVER; CUMULATIVE REMEDIES. Neither the Administrative
Agent nor any Lender shall by any act (except by a written instrument pursuant
to SECTION 15) be deemed to have waived any right or remedy hereunder or to have
acquiesced in any Default or Event of Default or in any breach of any of the
terms and conditions hereof. No failure to exercise, nor any delay in
exercising, on the part of the Administrative Agent or any Lender, any right,
power or privilege hereunder shall operate as a waiver thereof. No single or
partial exercise of any right, power or privilege hereunder shall preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. A waiver by the Administrative Agent or any Lender of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Administrative Agent or such Lender would otherwise
have on any future occasion. The rights and remedies herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of any
other rights or remedies provided by law.

                  15. WAIVERS AND AMENDMENTS; SUCCESSORS AND ASSIGNS; GOVERNING
LAW. None of the terms or provisions of this Pledge Agreement may be amended,
supplemented or otherwise modified except by a written instrument executed by
the Pledgor and the Administrative Agent; PROVIDED that any provision of this
Pledge Agreement may be waived by the Administrative Agent in a letter or
agreement executed by the Administrative Agent or by telex or facsimile
transmission from the Administrative Agent. This Pledge Agreement shall inure to
the benefit of the Administrative Agent and the Lenders and their respective
successors and assigns. THIS PLEDGE AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES UNDER THIS PLEDGE AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD
TO THE PRINCIPLES OF CONFLICT OF LAWS THEREOF OTHER THAN SECTION 5-1401 OF THE
GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK.

                  16. NOTICES. Notices may be given by mail, by telex or by
facsimile transmission, addressed or transmitted to the Person to which it is
being given at such Person's address or transmission number set forth in the
Credit Agreement and shall be effective (a) in the case of mail, three days
after deposit in the postal system, first class postage pre-paid, and (b) in the
case of telex or facsimile notices, when sent if receipt is confirmed by
telephone. The Pledgor and any issuer of Pledged Stock may change their
respective addresses and transmission numbers by written notice to the
Administrative Agent.

                  17. IRREVOCABLE AUTHORIZATION AND INSTRUCTION TO ISSUERS. The
Pledgor hereby authorizes and instructs each issuer of Pledged Stock to comply
with any instruction received by it from the Administrative Agent in writing
that (a) states that an Event of Default has occurred and (b) is otherwise in
accordance with the terms of this Pledge Agreement, without any other or further
instructions from the Pledgor, and the Pledgor agrees that such issuer shall be
fully protected in so complying.

                                       9

<PAGE>

                  18. AUTHORITY OF AGENT. The Pledgor acknowledges that the
rights and responsibilities of the Administrative Agent under this Pledge
Agreement with respect to any action taken by the Administrative Agent or the
exercise or non-exercise by the Administrative Agent of any option, voting
right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Pledge Agreement shall, as between the
Administrative Agent and the Lenders, be governed by the Credit Agreement and by
such other agreements with respect thereto as may exist from time to time among
them, but, as between the Administrative Agent and the Pledgor, the
Administrative Agent shall be conclusively presumed to be acting as agent for
the Lenders with full and valid authority so to act or refrain from acting, and
neither the Pledgor nor any issuer of Pledged Stock shall be under any
obligation, or entitlement, to make any inquiry respecting such authority.

                  19. TERMINATION; RELEASE. Upon the repayment of all the
Obligations in full and the termination of the Commitments, this Pledge
Agreement shall terminate, and the Administrative Agent, at the request of and
sole expense of the Pledgor, will execute and deliver to the Pledgor the proper
instruments (including Uniform Commercial Code termination statements on form
UCC-2 or UCC-3, as applicable) acknowledging the termination of this Pledge
Agreement, and will duly assign, transfer and deliver to the Pledgor (without
recourse and without any representation or warranty of any kind) such of the
Collateral as may be in the possession of the Administrative Agent and has not
theretofore been disposed of or otherwise applied or released.

                  20. COUNTERPARTS. This Pledge Agreement may be executed in
counterparts, and all of such counterparts taken together shall be deemed to
constitute one and the same instrument.

                           interest created through a pledge of such Investment
                           Property pursuant to a Pledge Agreement, shall be in
                           an amount equal to 65% of such Capital Stock or such
                           higher percentage as may be allowed under Treas. Reg.
                           Section 1.956-2(c)(2) under the Code; and

                  (x)      to the extent not otherwise included, all Proceeds
                           and products of any and all of the foregoing;

PROVIDED that nothing contained herein shall create a collateral assignment with
respect to any Contract if the grant of such collateral assignment is (or is
determined by non-appealable adjudication of a court or other dispute resolution
tribunal to be) prohibited by the terms of such Contract.

                  3. RIGHTS OF ADMINISTRATIVE AGENT AND LENDERS; LIMITATIONS ON
ADMINISTRATIVE AGENT'S AND LENDERS' OBLIGATIONS.

                  (a) GRANTOR REMAINS LIABLE UNDER ACCOUNTS AND CONTRACTS.
Anything herein to the contrary notwithstanding, the Grantor shall remain liable
under each of the Accounts and Contracts to observe and perform all the
conditions and obligations to be observed and performed by it thereunder, all in
accordance with the terms of any agreement giving rise to each such Account and
in accordance with and pursuant to the terms and provisions of each such
Contract. Neither the Administrative Agent nor any Lender shall have any
obligation or liability under any Account (or any agreement giving rise thereto)
or under any Contract by reason of or arising out of this Security Agreement or
the receipt by the Administrative Agent or any such Lender of any payment
relating to such Account or Contract pursuant hereto, nor shall the
Administrative Agent or any Lender be obligated in any manner to perform any of
the obligations of the Grantor under or pursuant to any Account (or any
agreement giving rise thereto) or under or pursuant to any Contract, to make any
payment, to make any inquiry as to the nature or the sufficiency of any payment
received by it or as to the sufficiency of any performance by any party under
any Account (or any agreement giving rise thereto) or under any Contract, 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 it or to
which it may be entitled at any time or times.

                  (b) NOTICE TO ACCOUNT DEBTORS AND CONTRACTING PARTIES. At any
time after the occurrence and during the continuance of an Event of Default, the
Administrative Agent shall have the right at any time, upon written notice to
the Grantor of its intention to do so, to notify account debtors or obligors on
the Accounts and parties to the Contracts that the Accounts and the Contracts
have been assigned to the Administrative Agent for the ratable benefit of the
Lenders and that payments due or to become due to the Grantor in respect thereof
shall be made directly to the Administrative Agent and, upon such notification,
and at the expense of the Grantor, to enforce collection of any such Accounts.
The Administrative Agent may, at any time, in its own name or in the name of the
Lenders or the Grantor communicate with account debtors on the Accounts and
parties to the Contracts to verify with them to its satisfaction the existence,
amount and terms of any Accounts or Contracts. Unless an Event of Default shall
have occurred and be continuing, the Administrative Agent shall not exercise its
right under this clause (b) more than once in any 12-month period.

                  (c) COLLECTIONS ON ACCOUNTS. The Administrative Agent hereby
authorizes the Grantor to collect the Accounts; PROVIDED that the Administrative
Agent may curtail or terminate said authority at any time after the occurrence
of an Event of Default. If required by the Administrative Agent at any time
after the occurrence and during the continuance of an Event of Default, any
payments of Accounts, when collected by the Grantor, shall be forthwith (and, in
any event, within two Business Days) deposited by the Grantor in the exact form
received, duly endorsed by the Grantor to the Administrative Agent if required,
in a special collateral account

                                       4

<PAGE>

maintained by the Administrative Agent, subject to withdrawal by the
Administrative Agent for the account of the Lenders only, as hereinafter
provided, and, until so turned over, shall be held by the Grantor in trust for
the Administrative Agent and the Lenders, segregated from other funds of the
Grantor. Each deposit of any such Proceeds shall be accompanied by a report
identifying in reasonable detail the nature and source of the payments included
in the deposit. All Proceeds constituting collections of Accounts while held by
the Administrative Agent (or by the Grantor in trust for the Administrative
Agent and the Lenders) shall continue to be collateral security for all the
Guarantee Obligations and shall not constitute payment thereof until applied as
hereinafter provided. At such intervals as may be agreed upon by the Grantor and
the Administrative Agent, or, if an Event of Default shall have occurred and be
continuing, at any time at the Administrative Agent's election, the
Administrative Agent shall apply all or any part of the funds on deposit in said
special collateral account on account of the Guarantee Obligations in such order
as the Administrative Agent may elect, and any part of such funds which the
Administrative Agent elects not so to apply and deems not required as collateral
security for the obligations shall be paid over from time to time by the
Administrative Agent to the Grantor or to whomsoever may lawfully be entitled to
receive the same (it being understood that (i) prior to any Event of Default
that is continuing, the Grantor shall be permitted to use such funds in the
operation of its business in a manner consistent with the terms of the Credit
Agreement and (ii) within fifteen days after the occurrence of any Event of
Default, the Administrative Agent shall, in its sole discretion, either apply
such funds in payment of the Guarantee Obligations in such order as the
Administrative Agent may elect or permit the Grantor to use such funds in the
operation of its business). Upon the occurrence of an Event of Default that is
continuing, at the Administrative Agent's request, the Grantor shall deliver to
the Administrative Agent all original and other documents evidencing, and
relating to, the agreements and transactions which gave rise to the Accounts,
including, without limitation, all original orders, invoices and shipping
receipts.

                  (d) ANALYSIS OF ACCOUNTS. The Administrative Agent shall have
the right to make test verifications of the Accounts in any manner and through
any medium that it reasonably considers advisable, and the Grantor shall furnish
all such assistance and information as the Administrative Agent may require in
connection therewith; PROVIDED that the Administrative Agent shall use its
reasonable efforts to minimize any disruption of the Grantor's business
resulting from such verifications. At any time and from time to time if the
Administrative Agent concludes in its reasonable judgment, based upon its
evaluation of the general creditworthiness of the Grantor, that such examination
is required, and so requests, the Grantor at its own expense shall cause
independent public accountants or other parties that are not Affiliates of the
Grantor and are reasonably satisfactory to the Administrative Agent to furnish
to the Administrative Agent reports showing reconciliations, aging and test
verifications of, and trial balances for, the Accounts. Unless an Event of
Default shall have occurred and be continuing, the Administrative Agent shall
not exercise its right under this clause (d) more than once in any 12-month
period.

                  4. REPRESENTATIONS AND WARRANTIES. The Grantor hereby
represents and warrants that:

                  (a) TITLE; NO OTHER LIENS. Except as permitted under Section
6.3 of the Credit Agreement, the Grantor owns or has a valid leasehold interest
in each item of the Collateral free

                                       5

<PAGE>

and clear of any and all Liens or claims of others. Except as permitted under
Section 6.3(e) of the Credit Agreement, no security agreement, financing
statement or other public notice with respect to all or any part of the
Collateral is on file or of record in any public office, except (i) such as may
have been filed in favor of the Administrative Agent, for the ratable benefit of
the Lenders, pursuant to this Security Agreement and (ii) financing statements
filed by lessors solely for information purposes in respect of "true" leases.

                  (b) PERFECTED FIRST PRIORITY LIENS. Except as permitted under
Section 6.3(e) of the Credit Agreement, the Liens granted pursuant to this
Security Agreement will, upon the filing of appropriate financing statements,
constitute valid and perfected first priority Liens on the Collateral in favor
of the Administrative Agent, for the ratable benefit of the Lenders, and against
any owner or purchaser of the real property where any of the Equipment is
located and any present or future creditor obtaining a Lien on such real
property, except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditor's rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

                  (c) ACCOUNTS. The amount represented by the Grantor to the
Lenders from time to time as owing by each account debtor or by all account
debtors in respect of the Accounts will at such time be the correct amount
actually owing by such account debtor or debtors thereunder. No amount payable
to the Grantor under or in connection with any Account is evidenced by any
Instrument or Chattel Paper which has not been delivered to the Administrative
Agent. The place where the Grantor keeps its records concerning the Accounts is
c/o Willis Stein & Partners, 227 West Monroe Street, Suite 4300, Chicago, IL
60606.

                  (d) CONTRACTS. Except as set forth in Schedule 3.4 to the
Credit Agreement, no consent of any party (other than the Grantor) to any
Contract is required in connection with the execution, delivery and performance
by the Grantor of this Security Agreement. Each Contract is in full force and
effect and constitutes a valid and legally enforceable obligation of the parties
thereto, except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditor's rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law). No consent or
authorization of, filing with or other act by or in respect of any Governmental
Authority is required in connection with the execution, delivery or performance
by the Grantor of, or the validity or enforceability of, any of the Contracts by
any party thereto other than those which have been duly obtained, made or
performed, are in full force and effect and do not subject the scope of any such
Contract to any material adverse limitation, either specific or general in
nature. Neither the Grantor nor (to the best of the Grantor's knowledge) any
other party to any Contract is in default in any material respect in the
performance or observance of any of the terms thereof. The Grantor has fully
performed in all material respects all its obligations under each Contract. The
right, title and interest of the Grantor in, to and under each Contract are not
subject to any defense, offset, counterclaim or claim which would materially
adversely affect the value of such Contract as Collateral, nor have any of the
foregoing been asserted or alleged against the Grantor as to any Contract. The
Grantor has delivered to the Administrative Agent a complete and correct copy of
each material Contract, including all amendments, supplements and other
modifications thereto and will deliver any other Contract which the
Administrative Agent may request. No amount payable to the Grantor under or in

                                       6

<PAGE>

connection with any Contract is evidenced by any Instrument or Chattel Paper
which has not been delivered to the Administrative Agent.

                  (e) INVENTORY AND EQUIPMENT. The Inventory and the Equipment
are kept at the locations listed on Schedule I hereto.

                  (f) CHIEF EXECUTIVE OFFICE. The Grantor's chief executive
office and chief place of business is located at c/o Willis Stein & Partners,
227 West Monroe Street, Suite 4300, Chicago, IL 60606.

                  (g) FARM PRODUCTS. None of the Collateral constitutes, or is
the Proceeds of, Farm Products.

                  (h) GOVERNMENTAL OBLIGORS. None of the obligors on any
Accounts, and none of the parties to any Contracts, is a Governmental Authority.

                  (i) INVESTMENT PROPERTY. The Investment Property consists of
the items set forth on Annex A.

                  5. COVENANTS. The Grantor covenants and agrees with the
Administrative Agent and the Lenders that, from and after the date of this
Security Agreement until the Obligations are paid in full and the Commitments
are terminated:

                  (a) FURTHER DOCUMENTATION; PLEDGE OF INSTRUMENTS AND CHATTEL
PAPER. At any time and from time to time, upon the written request of the
Administrative Agent, and at the sole expense of the Grantor, the Grantor will
promptly and duly execute and deliver such further instruments and documents and
take such further action as the Administrative Agent may reasonably request for
the purpose of obtaining or preserving the full benefits of this Security
Agreement and of the rights and powers herein granted, including, without
limitation, the filing of any financing or continuation statements under the
Uniform Commercial Code in effect in any jurisdiction with respect to the Liens
created hereby. The Grantor also hereby authorizes the Administrative Agent to
file any such financing or continuation statement without the signature of the
Grantor to the extent permitted by applicable law. A carbon, photographic or
other reproduction of this Security Agreement shall be sufficient as a financing
statement for filing in any jurisdiction. If any amount payable under or in
connection with any of the Collateral shall be or become evidenced by any
Instrument or Chattel Paper, such Instrument or Chattel Paper shall be
immediately delivered to the Administrative Agent, duly endorsed in a manner
satisfactory to the Administrative Agent, to be held as Collateral pursuant to
this Security Agreement.

                  (b) INDEMNIFICATION. The Grantor agrees to pay, and to save
the Administrative Agent and the Lenders harmless from, any and all liabilities,
costs and expenses (including, without limitation, legal fees and expenses) (i)
with respect to, or resulting from, any delay in paying any and all excise,
sales or other taxes which may be payable or determined to be payable with
respect to any of the Collateral, (ii) with respect to, or resulting from, any
delay in complying with any Requirement of Law applicable to any of the
Collateral or (iii) in connection with any of the transactions contemplated by
this Security Agreement, except resulting from the Administrative Agent's or any
Lender's gross negligence or willful misconduct. In any suit,

                                       7

<PAGE>

proceeding or action brought by the Administrative Agent or any Lender under any
Account or Contract for any sum owing thereunder, or to enforce any provisions
of any Account or Contract, the Grantor will save, indemnify and keep the
Administrative Agent and such Lender harmless from and against all expense, loss
or damage suffered by reason of any defense, setoff, counterclaim, recoupment or
reduction or liability whatsoever of the account debtor or obligor thereunder,
arising out of a breach by the Grantor of any obligation thereunder or arising
out of any other agreement, indebtedness or liability at any time owing to or in
favor of such account debtor or obligor or its successors from the Grantor,
except resulting from the Administrative Agent's or any Lender's gross
negligence or willful misconduct.

                  (c) MAINTENANCE OF RECORDS. The Grantor will keep and maintain
at its own cost and expense satisfactory and complete records of the Collateral,
including, without limitation, a record of all payments received and all credits
granted with respect to the Accounts. The Grantor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby in such manner as the Administrative Agent may
request. For the Administrative Agent's and the Lenders' further security, the
Administrative Agent, for the ratable benefit of the Lenders, shall have a
security interest in all the Grantor's books and records pertaining to the
Collateral, and the Grantor shall, during the continuance of a Default under
Section 7.1(a) of the Credit Agreement or Section 7.1(c) of the Credit Agreement
as it relates to Section 6.1 of the Credit Agreement, turn over copies of such
books and records and during the continuation of an Event of Default turn over
any such books and records, in each case, to the Administrative Agent or to its
representatives at the request of the Administrative Agent.

                  (d) RIGHT OF INSPECTION. The Administrative Agent and the
Lenders shall at all times have full and free access during normal business
hours and, so long as no Event of Default shall have occurred and be continuing,
upon reasonable prior notice, to all books, correspondence and records of the
Grantor, and the Administrative Agent and the Lenders and their respective
representatives may examine the same, take extracts therefrom and make
photocopies thereof, and the Grantor agrees to render to the Administrative
Agent and the Lenders, at the Grantor's cost and expense, such clerical and
other assistance as may be reasonably requested with regard thereto. The
Administrative Agent and the Lenders and their respective representatives shall
at all times and, so long as no Event of Default shall have occurred and be
continuing, upon reasonable prior notice, also have the right to enter into and
upon any premises where any of the Inventory or Equipment is located for the
purpose of inspecting the same, observing its use or otherwise protecting its
interests therein.

                  (e) COMPLIANCE WITH LAWS. The Grantor will comply in all
material respects with all Requirements of Law applicable to the Collateral or
any part thereof or to the operation of the Grantor's business; PROVIDED that
the Grantor may contest any Requirement of Law in any reasonable manner which
shall not, in the sole opinion of the Administrative Agent, adversely affect the
Administrative Agent's or the Lenders' rights or the priority of their Liens on
the Collateral.

                  (f) COMPLIANCE WITH TERMS OF CONTRACTS. The Grantor will
perform and comply in all material respects with all its obligations under the
Contracts and all its other Contractual Obligations relating to the Collateral.

                                       8

<PAGE>

                  (g) PAYMENT OF OBLIGATIONS. The Grantor will pay promptly when
due all taxes, assessments and governmental charges or levies imposed upon the
Collateral or in respect of its income or profits therefrom, as well as all
claims of any kind (including, without limitation, claims for labor, materials
and supplies) against or with respect to the Collateral, except that no such
charge need be paid if (i) the validity thereof is being contested in good faith
by appropriate proceedings, (ii) such proceedings do not involve any material
danger of the sale, forfeiture or loss of any of the Collateral or any interest
therein and (iii) such charge is adequately reserved against on the Grantor's
books in accordance with GAAP.

                  (h) LIMITATION ON LIENS ON COLLATERAL. The Grantor will not
create, incur or permit to exist, will defend the Collateral against, and will
take such other action as is necessary to remove, any Lien or claim on or to the
Collateral, other than the Liens created hereby and other than as permitted
pursuant to Section 6.3 of the Credit Agreement, and will defend the right,
title and interest of the Administrative Agent and the Lenders in and to any of
the Collateral against the claims and demands of all Persons whomsoever.

                  (i) LIMITATIONS ON DISPOSITIONS OF COLLATERAL. The Grantor
will not sell, transfer, lease or otherwise dispose of any of the Collateral, or
attempt, offer or contract to do so except as permitted pursuant to Section 6.6
of the Credit Agreement.

                  (j) LIMITATIONS ON MODIFICATIONS, WAIVERS, EXTENSIONS OF
CONTRACTS AND AGREEMENTS GIVING RISE TO ACCOUNTS. Subject to subsection (k)
below, the Grantor will not (i) amend, modify, terminate or waive any provision
of any Material Contract or any agreement giving rise to an Account in any
manner which could reasonably be expected to materially adversely affect the
value of such Contract or Account as Collateral, (ii) fail to exercise promptly
and diligently each and every material right which it may have under each
Contract and each agreement giving rise to an Account (other than any right of
termination) or (iii) fail to deliver to the Administrative Agent a copy of each
material demand, notice or document received by it relating in any way to any
Contract or any agreement giving rise to an Account. As used in this clause (j),
a "Material Contract" shall mean any contract with a stated duration (including
any extension periods contained therein) of more than 12 months and with a value
of more than $750,000.

                  (k) LIMITATIONS ON DISCOUNTS, COMPROMISES, EXTENSIONS OF
ACCOUNTS. Other than in the ordinary course of business, the Grantor will not
grant any extension of the time of payment of any of the Accounts, compromise,
compound or settle the same for less than the full amount thereof, release,
wholly or partially, any Person liable for the payment thereof, or allow any
credit or discount whatsoever thereon.

                  (l) MAINTENANCE OF EQUIPMENT. The Grantor will maintain each
item of Equipment not subject to Section 6.6(a) of the Credit Agreement in good
operating condition, ordinary wear and tear and immaterial impairments of value
and damage by the elements excepted, and will provide all maintenance, service
and repairs necessary for such purpose.

                  (m) MAINTENANCE OF INSURANCE. The Grantor will maintain, with
financially sound and reputable companies, insurance policies as required under
the Credit Agreement. All such policies shall (i) contain a breach of warranty
clause in favor of the Administrative Agent

                                       9

<PAGE>

and the Lenders, (ii) provide that no cancellation, material reduction in amount
or material change in coverage thereof shall be effective until at least 30 days
after receipt by the Administrative Agent and the Lenders of written notice
thereof, (iii) name the Administrative Agent as loss payee of each such policy,
(iv) name the Administrative Agent and the Lenders as insured to the extent of
their interests under each such policy and (v) be reasonably satisfactory in all
material respects to the Administrative Agent. The Grantor shall deliver to the
Administrative Agent and each Lender upon request, full information as to the
insurance carried, including certified copies of policies and certificates of
insurance from a recognized insurance broker reasonably acceptable to the
Administrative Agent.

                  (n) FURTHER IDENTIFICATION OF COLLATERAL. The Grantor will
furnish to the Administrative Agent and the Lenders from time to time statements
and schedules further identifying and describing the Collateral and such other
reports in connection with the Collateral as the Administrative Agent may
reasonably request, all in reasonable detail.

                  (o) NOTICES. The Grantor will advise the Administrative Agent
promptly, in reasonable detail, at its address set forth in the Credit
Agreement, (i) of any Lien (other than Liens created hereby or permitted under
the Credit Agreement) on, or claim asserted against, any of the Collateral and
(ii) of the occurrence of any other event which could reasonably be expected to
have a material adverse effect on the aggregate value of the Collateral or on
the Liens created hereunder.

                  (p) CHANGES IN LOCATIONS, NAME, ETC. Unless the Grantor gives
30 days' prior written notice to the Administrative Agent, the Grantor will not
(i) change the location of its chief executive office/chief place of business
from that specified in Section 4(f) or remove its books and records from the
location specified in Section 4(c), (ii) permit any of the Inventory or
Equipment to be kept at a location other than those listed on Schedule I hereto
or (iii) change its name, identity or corporate structure to such an extent that
any financing statement filed by the Administrative Agent in connection with
this Security Agreement would become seriously misleading.

                  6. ADMINISTRATIVE AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT.

                  (a) POWERS. The Grantor hereby irrevocably constitutes and

power of substitution, as its true and lawful attorney-in-fact with full
irrevocable power and authority in the place and stead of the Grantor and in the

Agreement, to take any and all appropriate action and to execute any and all
documents and instruments which may be necessary or desirable to accomplish the
purposes of this Security Agreement, and, without limiting the generality of the
foregoing, the Grantor hereby gives the Administrative Agent the power and
right, on behalf of the Grantor, without notice to or assent by the Grantor, to

         other Collateral, at any time when any Event of Default

         file any claim or to take any other action or proceeding in any court

         become due thereunder directly to the Administrative Agent or as the
         Administrative Agent shall direct; (B) to ask or demand for, collect,

         sell, transfer, pledge and make any agreement with respect to or
         otherwise deal with any of the Collateral as fully and completely as
         though the Administrative Agent were the absolute owner thereof for all
         purposes, and to do, at the Administrative Agent's option and the
         Grantor's expense, at any time, or from time to time, all acts and
         things which the Administrative Agent deems necessary to protect,
         preserve or realize upon the Collateral and the Administrative Agent's
         and the Lenders' Liens thereon and to effect the intent of this
         Security Agreement, all as fully and effectively as the Grantor might
         do.

The Grantor 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 shall be irrevocable.

                  (b) OTHER POWERS. The Grantor also authorizes the
Administrative Agent and the Lenders, at any time and from time to time, to
execute, in connection with the sale provided for in this SECTION 6 or in
SECTION 9 hereof, any endorsements, assignments or other instruments of
conveyance or transfer with respect to the Collateral.

                  (c) NO DUTY ON ADMINISTRATIVE AGENT'S OR LENDERS' PART. The
powers conferred on the Administrative Agent and the Lenders hereunder are
solely to protect the

                                       11

<PAGE>

Administrative Agent's and the Lenders' interests in the Collateral and shall
not impose any duty upon the Administrative Agent or any Lender to exercise any
such powers. The Administrative Agent and the Lenders shall be accountable only
for amounts that they actually receive as a result of the exercise of such
powers, and neither they nor any of their officers, directors, employees or
agents shall be responsible to the Grantor for any act or failure to act
hereunder, except for their own gross negligence or willful misconduct.

                  7. PERFORMANCE BY ADMINISTRATIVE AGENT OF GRANTOR'S
OBLIGATIONS. If the Grantor fails to perform or comply with any of its
agreements contained herein and the Administrative Agent, as provided for by the
terms of this Security Agreement, shall itself perform or comply, or otherwise
cause performance or compliance, with such agreement, the expenses of the
Administrative Agent incurred in connection with such performance or compliance,
together with interest thereon at a rate per annum 2% above the Alternate Base
Rate, shall be payable by the Grantor to the Administrative Agent on demand and
shall constitute Guarantee Obligations secured hereby.

                  8. PROCEEDS. In addition to the rights of the Administrative
Agent and the Lenders specified in Section 3(c) with respect to payments of
Accounts, it is agreed that if an Event of Default shall occur and be continuing
(a) upon written notice by the Administrative Agent to the Grantor, all Proceeds
received by the Grantor consisting of cash, checks and other near-cash items
shall be held by the Grantor in trust for the Administrative Agent and the
Lenders, segregated from other funds of the Grantor, and, forthwith upon receipt
by the Grantor, shall be turned over to the Administrative Agent in the exact
form received by the Grantor (duly endorsed by the Grantor to the Administrative
Agent, if required), and (b) any and all such Proceeds received by the
Administrative Agent (whether from the Grantor or otherwise) may, in the sole
discretion of the Administrative Agent, (i) be held by the Administrative Agent
for the ratable benefit of the Lenders as collateral security for the Guaranteed
Obligations, and/or (ii) then or at any time thereafter either (x) be applied by
the Administrative Agent for the ratable benefit of the Lenders against the
Guarantee Obligations (whether matured or unmatured), such application to be in
such order as the Administrative Agent shall elect, or (y) at the sole
discretion of the Administrative Agent, be available for use by the Grantor in
the operation of its business. Any balance of such Proceeds remaining after the
Guarantee Obligations shall have been paid in full and the Commitments shall
have been terminated shall be paid over to the Grantor or to whomsoever may be
lawfully entitled to receive the same.

                  9. REMEDIES. If an Event of Default shall occur and be
continuing, the Administrative Agent, on behalf of the Lenders, may exercise, in
addition to all other rights and remedies granted to them in this Security
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Guarantee Obligations, all rights and remedies of a secured
party under the Code. Without limiting the generality of the foregoing, the
Administrative Agent, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law referred to below) to or upon the Grantor, any guarantor, or any
other Person (all and each of which demands, defenses, advertisements and
notices being hereby waived to the maximum extent permitted by applicable law),
may in such circumstances forthwith collect, receive, appropriate and realize
upon the Collateral, or any part thereof, and/or may forthwith sell, lease,
assign, give option or options to purchase, or otherwise dispose of and deliver
the Collateral or any part thereof (or contract to do

                                       12

<PAGE>

any of the foregoing), in one or more parcels at public or private sale or
sales, at any exchange, broker's board or office of the Administrative Agent or
any Lender or elsewhere upon such terms and conditions as it may deem advisable
and at such prices as it may deem best, for cash or on credit or for future
delivery without assumption of any credit risk. The Administrative Agent or any
Lender shall have the right upon any such public sale or sales, and, to the
extent permitted by applicable law, upon any such private sale or sales, to
purchase the whole or any part of the Collateral so sold, free of any right or
equity of redemption in the Grantor, which right or equity is hereby waived or
released to the maximum extent permitted by applicable law. The Grantor further
agrees, at the Administrative Agent's request, to assemble the Collateral and
make it available to the Administrative Agent at such places as the
Administrative Agent shall reasonably select, whether at the Grantor's premises
or elsewhere. The Administrative Agent shall apply the net proceeds of any such
collection, recovery, receipt, appropriation, realization or sale, after
deducting all reasonable costs and expenses of every kind incurred therein or
incidental to the care or safekeeping of any of the Collateral or in any way
relating to the Collateral or the rights of the Administrative Agent and the
Lenders hereunder, including, without limitation, reasonable attorneys' fees and
disbursements, to the payment in whole or in part of the Guarantee Obligations,
in such order as the Administrative Agent may elect, and only after such
application and after the payment by the Administrative Agent of any other
amount required by any provision of law, including, without limitation, Section
9-504(i)(c) of the Code, need the Administrative Agent account for the surplus,
if any, to the Grantor. To the extent permitted by applicable law, the Grantor
waives all claims, damages and demands it may acquire against the Administrative
Agent or any Lender arising out of the exercise by them of any rights hereunder.
If any notice of a proposed sale or other disposition of Collateral shall be
required by law, such notice shall be deemed reasonable and proper if given at
least 10 days before such sale or other disposition. The Grantor shall remain
liable for any deficiency if the proceeds of any sale or other disposition of
the Collateral are insufficient to pay the Guarantee Obligations and the fees
and disbursements of any attorneys employed by the Administrative Agent or any
Lender to collect such deficiency.

                  10. LIMITATION ON DUTIES REGARDING PRESERVATION OF COLLATERAL.
The Administrative Agent's sole duty with respect to the custody, safekeeping
and physical preservation of the Collateral in its possession, under Section
9-207 of the Code or otherwise, shall be to deal with it in the same manner as
the Administrative Agent deals with similar property for its own account.
Neither the Administrative Agent, any Lender, nor any of their respective
directors, officers, employees or agents shall be liable for failure to demand,
collect or realize upon all or any part of the Collateral or for any delay in
doing so or shall be under any obligation to sell or otherwise dispose of any
Collateral upon the request of the Grantor or otherwise.

                  11. POWERS COUPLED WITH AN INTEREST. All authorizations and
agencies herein contained with respect to the Collateral are irrevocable and
powers coupled with an interest.

                  12. LIMITATION ON LINES OF BUSINESS. Nothing in this Security
Agreement shall be deemed or construed as modifying in any way the restrictions
on the Grantor's activities as set forth in Section 6.14 of the Credit
Agreement.

                                       13

<PAGE>

                  13. SEVERABILITY. Any provision of this Security Agreement
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

                  14. SECTION HEADINGS. The section headings used in this
Security Agreement are for convenience of reference only and are not to affect
the construction hereof or be taken into consideration in the interpretation
hereof.

                  15. NO WAIVER; CUMULATIVE REMEDIES. Neither the Administrative
Agent nor any Lender shall by any act (except by a written instrument pursuant
to SECTION 16), delay, indulgence, omission or otherwise be deemed to have
waived any right or remedy hereunder or to have acquiesced in any Default or
Event of Default or in any breach of any of the terms and conditions hereof. No
failure to exercise, nor any delay in exercising, on the part of the
Administrative Agent or any Lender, any right, power or privilege hereunder
shall operate as a waiver thereof. No single or partial exercise of any right,
power or privilege hereunder shall preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. A waiver by the
Administrative Agent or any Lender of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy which the
Administrative Agent or such Lender would otherwise have on any future occasion.
The rights and remedies herein provided are cumulative, may be exercised singly
or concurrently and are not exclusive of any rights or remedies provided by law.

                  16. WAIVERS AND AMENDMENTS; SUCCESSORS AND ASSIGNS. None of
the terms or provisions of this Security Agreement may be waived, amended,
supplemented or otherwise modified except by a written instrument executed by
the Grantor and the Administrative Agent; PROVIDED that any provision of this
Security Agreement may be waived by the Administrative Agent in a written letter
or agreement executed by the Administrative Agent or by telex or facsimile
transmission from the Administrative Agent. This Security Agreement shall be
binding upon the successors and assigns of the Grantor and shall inure to the
benefit of the Administrative Agent and the Lenders and their respective
successors and assigns.

                  17. GOVERNING LAW. THIS SECURITY AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS SECURITY AGREEMENT SHALL BE GOVERNED BY,
AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW
YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS THEREOF OTHER THAN
SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK, EXCEPT
FOR PERFECTION AND ENFORCEMENT OF SECURITY INTERESTS AND LIENS IN OTHER
JURISDICTIONS TO THE EXTENT THE LAW OF ANOTHER JURISDICTION IS MANDATORILY
APPLICABLE PURSUANT TO THE LAWS OF SUCH JURISDICTION.

                  18. NOTICES. Notices hereunder may be given by mail, by telex
or by facsimile transmission, addressed or transmitted to the Person to which it
is being given at such Person's address or transmission number set forth in the
Credit Agreement and shall be effective (a) in the case of mail, three days

                                       14

the case of telex or facsimile notices, when sent if receipt is confirmed by
telephone. The Grantor may change its address and transmission number by written
notice to the Administrative Agent, and the Administrative Agent or any Lender
may change its address and transmission number by written notice to the Grantor
and, in the case of any Lender, to the Administrative Agent.

                  19. AUTHORITY OF ADMINISTRATIVE AGENT. The Grantor
acknowledges that the rights and responsibilities of the Administrative Agent
under this Security Agreement with respect to any action taken by the
Administrative Agent or the exercise or non-exercise by the Administrative Agent
of any option, right, request, judgment or other right or remedy provided for
herein or resulting or arising out of this Security Agreement shall, as between
the Administrative Agent and the Lenders, be governed by the Credit Agreement
and by such other agreements with respect thereto as may exist from time to time
among them, but, as between the Administrative Agent and the Grantor, the
Administrative Agent shall be conclusively presumed to be acting as agent for
the Lenders with full and valid authority so to act or refrain from acting, and
the Grantor shall not be under any obligation, or entitlement, to make any
inquiry respecting such authority.

                  20. COUNTERPARTS. This Security Agreement may be executed in
counterparts, and all of such counterparts taken together shall be deemed to
constitute one and the same instrument.

                  5. COVENANTS. The Pledgor covenants and agrees with the
Administrative Agent and the Lenders that, from and after the date of this
Pledge Agreement until the Obligations are paid in full and the Commitments are
terminated:

                  (a) If the Pledgor, as a result of its ownership of the
         Pledged Stock, shall become entitled to receive or shall receive any
         Capital Stock certificates of any issuer of Pledged Stock (including,
         without limitation, any certificate representing a distribution of
         Capital Stock in connection with any reclassification, increase or
         reduction of capital or any certificate issued in connection with any
         reorganization), option or rights, whether in addition to, in
         substitution of, as a conversion of, or in exchange for any of the
         Pledged Stock, or otherwise in respect thereof, the Pledgor shall
         accept the same as the agent of the Administrative Agent and the
         Lenders, hold the same in trust for the benefit of the Administrative
         Agent and the Lenders and deliver the same forthwith to the
         Administrative Agent in the exact form received, duly endorsed by the
         Pledgor to the Administrative Agent, if required, together with an
         undated power covering such certificate duly executed in blank by the
         Pledgor to be held by the Administrative Agent, subject to the terms
         hereof, as additional collateral security for the Guarantee
         Obligations. Any sums paid upon or in respect of the Pledged Stock upon
         the liquidation or dissolution of any issuer of Pledged Stock and any
         distribution of capital in respect of the Pledged Stock or any cash
         pursuant to the recapitalization or reclassification of the capital of
         any issuer of Pledged Stock or pursuant to the reorganization thereof
         shall, within 15 days after receipt thereof by the Administrative Agent
         and in the sole discretion of the Administrative Agent, either be (i)
         applied in payment of the Obligations in such order as the
         Administrative Agent may elect or (ii) paid over to the Pledgor for its
         use in the operation of its business, and in case any distribution of
         capital shall be made on or in respect of the Pledged Stock or any
         property shall be distributed upon or with respect to the Pledged Stock
         pursuant to the recapitalization or reclassification of the capital of
         any issuer of Pledged Stock or pursuant to the reorganization thereof,
         the property so distributed shall be delivered to the Administrative
         Agent to be held by it hereunder as additional collateral security for
         the Guarantee Obligations. If any sums of money or property so paid or
         distributed in respect of the Pledged Stock shall be received by the

                                       4

<PAGE>

         Pledgor, the Pledgor shall, until such money or property is paid or
         delivered to the Administrative Agent, hold such money or property in
         trust for the benefit of the Lenders, segregated from other funds of
         the Pledgor, as additional collateral security for the Guarantee
         Obligations.

                  (b) Without the prior written consent of the Administrative
         Agent, the Pledgor will not (i) vote to enable, or take any other
         action to permit, any issuer of Pledged Stock to issue Capital Stock or
         other equity securities of any nature or to issue any other securities
         convertible into or granting the right to purchase or exchange for any
         Capital Stock or other equity securities of any nature of any issuer of
         Pledged Stock (other than any Capital Stock or other equity securities
         constituting Management Shares), (ii) sell, assign, transfer, exchange,
         or otherwise dispose of, or grant any option with respect to, the
         Collateral, or (iii) create, incur or permit to exist any other Lien or
         option in favor of, or any claim of any Person with respect to, any of
         the Collateral, or any interest therein, except for the Lien provided
         for by this Pledge Agreement. The Pledgor will defend and will
         indemnify and hold harmless the Administrative Agent and the Lenders
         against the claims and demands of all Persons whomsoever with respect
         to any claim arising from or in connection with the right, title and
         interest of the Administrative Agent and the Lenders in and to the
         Collateral.

                  (c) At any time and from time to time, upon the written
         request of the Administrative Agent, and at the sole expense of the
         Pledgor, the Pledgor will promptly and duly execute and deliver such
         further instruments and documents and take such further actions as the
         Administrative Agent may reasonably request for the purposes of
         obtaining or preserving the full benefits of this Pledge Agreement and
         of the rights and powers herein granted. If any amount payable under or
         in connection with any of the Collateral shall be or become evidenced
         by any promissory note, other instrument or chattel paper, such note,
         instrument or chattel paper shall be immediately delivered to the
         Administrative Agent, duly endorsed in a manner satisfactory to the
         Administrative Agent, to be held as Collateral pursuant to this Pledge
         Agreement.

                  (d) The Pledgor agrees to pay, and to save the Administrative
         Agent and the Lenders harmless from, any and all liabilities with
         respect to, or resulting from any delay in paying, any and all stamps,
         excise, sales or other taxes which may be payable or determined to be
         payable with respect to any of the Collateral or in connection with any
         of the transactions contemplated by this Pledge Agreement.

                  (e) The Pledgor agrees that, within 30 days of any
         corporation, limited liability company or similar entity becoming a
         Subsidiary (as defined in the Credit Agreement), in the case of shares
         of Capital Stock of such Subsidiary represented by one or more
         certificates, it shall (i) upon the request of the Administrative
         Agent, deliver to the Administrative Agent all such shares (or, in the
         case of any Foreign Subsidiary, 65% of such shares) owned by the
         Pledgor, together with, in each case, appropriate undated powers duly
         executed in blank and (ii) execute and deliver a new pledge agreement
         (or a supplement to this Pledge Agreement) covering such shares. Upon
         such delivery, such shares shall constitute a representation and
         warranty as of the date of such delivery that the representations and
         warranties contained in SECTION 4 above are true and correct on such

                                       5

<PAGE>

         date after giving effect to such delivery. The Pledgor shall also
         furnish to the Lenders such legal opinions confirming such
         representations and warranties as the Administrative Agent or any
         Lender may reasonably request.

                  6.       CASH DISTRIBUTIONS; VOTING RIGHTS.

                  Unless a Default or Event of Default shall have occurred and
be continuing, the Pledgor shall be permitted to receive all cash dividends,
distributions, interest and principal paid on the Pledged Stock to the extent
that such cash dividends, distributions, interest and principal are permitted in
the Credit Agreement and applicable laws; PROVIDED that any such cash dividends,
distributions, interest or principal received by the Pledgor during the pendency
of any Default (but prior to the occurrence of an Event of Default) shall be
returned promptly to the issuer of such cash dividends, distributions, interest
or principal, and any such cash dividends, distributions, interest or principal
received during the pendency of any Default but not returned prior to such
Default becoming an Event of Default or during the pendency of any Event of
Default shall be delivered promptly to the Administrative Agent. Unless an Event
of Default shall have occurred and be continuing, the Pledgor shall be permitted
to exercise all voting and limited liability company rights with respect to the
Pledged Stock; PROVIDED that no vote shall be cast or limited liability company
right exercised or other action taken which, in the Administrative Agent's
reasonable judgment, would impair the Collateral or which would be inconsistent
with or result in any violation of any provision of the Credit Agreement, the
Notes, the other Loan Documents or this Pledge Agreement.

                  7. RIGHTS OF THE LENDERS AND THE ADMINISTRATIVE AGENT. (a) If
an Event of Default shall occur and be continuing, (i) the Administrative Agent
shall have the right to receive any and all dividends, distributions, interest
and principal paid in respect of the Pledged Stock, and to make application
thereof to the Obligations in such order as the Administrative Agent may
determine and (ii) all of the Pledged Stock shall be registered in the name of
the Administrative Agent or its nominee, and the Administrative Agent or its
nominee may thereafter exercise (A) all voting, limited liability company and
other rights pertaining to the Pledged Stock, and (B) any and all rights of
conversion, exchange, subscription and any other rights, privileges or options,
pertaining to any of the Pledged Stock as if it were the absolute owner thereof
(including, without limitation, the right to exchange at its discretion any and
all the Pledged Stock upon the merger, consolidation, reorganization,
recapitalization or other fundamental change in the corporate structure of any
issuer of Pledged Stock, or upon the exercise by the Pledgor or the
Administrative Agent of any right, privilege or option pertaining to any of the
Pledged Stock, and in connection therewith, the right to deposit and deliver any
and all of the Pledged Stock with any committee, depositary, transfer agent,
registrar or other designated agency upon such terms and conditions as it may
determine), all without liability to the Administrative Agent except to account
for property actually received by it, but the Administrative Agent shall have no
duty to the Pledgor to exercise any such right, privilege or option and shall
not be responsible for any failure to do so or delay in so doing.

                  (b) The rights of the Administrative Agent and the Lenders
hereunder shall not be conditioned or contingent upon the pursuit by the
Administrative Agent or any Lender of any right or remedy against the Pledgor,
any issuer of Pledged Stock, any guarantor or against any other Person which may
be or become liable in respect of all or any part of the Obligations or against

                                      6

<PAGE>

any collateral security therefor, guarantee therefor or right of offset with
respect thereto. Neither the Administrative Agent nor any Lender shall be liable
for any failure to demand, collect or realize upon all or any part of the
Collateral or for any delay in doing so, nor shall the Administrative Agent be
under any obligation to sell or otherwise dispose of any Collateral upon the
request of the Pledgor or any other Person or to take any other action
whatsoever with regard to the Collateral or any part thereof.

                  8. REMEDIES. If an Event of Default shall occur and be
continuing, the Administrative Agent, on behalf of the Lenders, may exercise, in
addition to all other rights and remedies granted in this Pledge Agreement and
in any other instrument or agreement securing, evidencing or relating to the
Obligations, all rights and remedies of a secured party under the Code. Without
limiting the generality of the foregoing, the Administrative Agent, without
demand of performance or other demand, presentment, protest, advertisement or
notice of any kind (except any notice required by law referred to below) to or
upon the Pledgor, any issuer of Pledged Stock, any guarantor or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby
waived to the maximum extent permitted by law), may in such circumstances
forthwith collect, receive, appropriate and realize upon the Collateral, or any
part thereof, and/or may forthwith sell, assign, give option or options to
purchase or otherwise dispose of and deliver the Collateral or any part thereof
(or contract to do any of the foregoing), in one or more parcels at public or
private sale or sales, in the over-the-counter market, at any exchange, broker's
board or office of the Administrative Agent or any Lender or elsewhere upon such
terms and conditions as it may deem advisable and at such prices as it may deem
best, for cash or on credit or for future delivery without assumption of any
credit risk. The Administrative Agent or any Lender shall have the right upon
any such public sale or sales, and, to the extent permitted by law, upon any
such private sale or sales, to purchase the whole or any part of the Collateral
so sold free of any right or equity of redemption in the Pledgor, which right or
equity is hereby waived or released to the maximum extent permitted by law. The
Administrative Agent shall apply any Proceeds from time to time held by it and
the net proceeds of any such collection, recovery, receipt, appropriation,
realization or sale, after deducting all reasonable costs and expenses of every
kind incurred in respect thereof or incidental to the care or safekeeping of any
of the Collateral or in any way relating to the Collateral or the rights of the
Administrative Agent and the Lenders hereunder, including, without limitation,
attorneys' fees and disbursements of counsel to the Administrative Agent, to the
payment in whole or in part of the Obligations, in such order as the
Administrative Agent may elect, and only after such application and after the
payment by the Administrative Agent of any other amount required by any
provision of law, including, without limitation, Section 9-504(1)(c) of the
Code, need the Administrative Agent account for the surplus, if any, to the
Pledgor. To the extent permitted by applicable law, the Pledgor waives all
claims, damages and demands it may acquire against the Administrative Agent or
any Lender arising out of the exercise by them of any rights hereunder. If any
notice of a proposed sale or other disposition of Collateral shall be required
by law, such notice shall be deemed reasonable and proper if given at least 10
days before such sale or other disposition. The Pledgor shall remain liable for
any deficiency if the proceeds of any sale or other disposition of Collateral
are insufficient to pay the Obligations and the fees and disbursements of any
attorneys employed by the Administrative Agent or any Lender to collect such
deficiency.

                                  7

<PAGE>

                  9. PRIVATE SALES. (a) The Pledgor recognizes that the
Administrative Agent may be unable to effect a public sale of any or all the
Pledged Stock, by reason of certain prohibitions contained in the Securities Act
of 1933 (the "SECURITIES ACT") and applicable state securities laws or
otherwise, and may be compelled to resort to one or more private sales thereof
to a restricted group of purchasers which will be obliged to agree, among other
things, to acquire such securities for their own account for investment and not
with a view to the distribution or resale thereof. The Pledgor acknowledges and
agrees that any such private sale may result in prices and other terms less
favorable than if such sale were a public sale and, notwithstanding such
circumstances, agrees that any such private sale shall be deemed to have been
made in a commercially reasonable manner. The Administrative Agent shall be
under no obligation to delay a sale of any of the Pledged Stock for the period
of time necessary to permit any issuer of Pledged Stock or the Pledgor to
register such securities for public sale under the Securities Act, or under
applicable state securities laws, even if such issuer or the Pledgor would agree
to do so.

                  (b) The Pledgor further agrees to use its best efforts to do
or cause to be done all such other acts as may be necessary to make such sale or
sales of all or any portion of the Pledged Stock pursuant to this SECTION 9
valid and binding and in compliance with any and all other applicable
Requirements of Law. The Pledgor further agrees that a breach of any of the
covenants contained in this SECTION 9 will cause irreparable injury to the
Administrative Agent and the Lenders, that the Administrative Agent and the
Lenders have no adequate remedy at law in respect of such breach and, as a
consequence, that each and every covenant contained in this SECTION 9 shall be
specifically enforceable against the Pledgor, and the Pledgor hereby waives and
agrees not to assert any defenses against an action for specific performance of
such covenants except for a defense that no Event of Default has occurred under
the Credit Agreement.

                  10. LIMITATION ON DUTIES REGARDING COLLATERAL. The
Administrative Agent's sole duty with respect to the custody, safekeeping and
physical preservation of the Collateral in its possession, under Section 9-207
of the Code or otherwise, shall be to deal with it in the same manner as the
Administrative Agent deals with similar securities and property for its own
account. None of the Administrative Agent, the Lenders or any of their
respective directors, officers, employees or agents shall be liable for failure
to demand, collect or realize upon any of the Collateral or for any delay in
doing so or shall be under any obligation to sell or otherwise dispose of any
Collateral upon the request of the Pledgor or otherwise.

                  11. POWERS COUPLED WITH AN INTEREST. All authorizations and
agencies herein contained with respect to the Collateral are irrevocable and
powers coupled with an interest.

                  12. SEVERABILITY. Any provision of this Pledge Agreement which
is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

                  13. SECTION HEADINGS. The section headings used in this Pledge
Agreement are for convenience of reference only and are not to affect the
construction hereof or be taken into consideration in the interpretation hereof.

                                      8
<PAGE>

                  14. NO WAIVER; CUMULATIVE REMEDIES. Neither the Administrative
Agent nor any Lender shall by any act (except by a written instrument pursuant
to SECTION 15) be deemed to have waived any right or remedy hereunder or to have
acquiesced in any Default or Event of Default or in any breach of any of the
terms and conditions hereof. No failure to exercise, nor any delay in
exercising, on the part of the Administrative Agent or any Lender, any right,
power or privilege hereunder shall operate as a waiver thereof. No single or
partial exercise of any right, power or privilege hereunder shall preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. A waiver by the Administrative Agent or any Lender of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Administrative Agent or such Lender would otherwise
have on any future occasion. The rights and remedies herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of any
other rights or remedies provided by law.

                  15. WAIVERS AND AMENDMENTS; SUCCESSORS AND ASSIGNS; GOVERNING
LAW. None of the terms or provisions of this Pledge Agreement may be amended,
supplemented or otherwise modified except by a written instrument executed by
the Pledgor and the Administrative Agent; PROVIDED that any provision of this
Pledge Agreement may be waived by the Administrative Agent in a letter or
agreement executed by the Administrative Agent or by telex or facsimile
transmission from the Administrative Agent. This Pledge Agreement shall inure to
the benefit of the Administrative Agent and the Lenders and their respective
successors and assigns. THIS PLEDGE AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES UNDER THIS PLEDGE AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD
TO THE PRINCIPLES OF CONFLICT OF LAWS THEREOF OTHER THAN SECTION 5-1401 OF THE
GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK.

                  16. NOTICES. Notices may be given by mail, by telex or by
facsimile transmission, addressed or transmitted to the Person to which it is
being given at such Person's address or transmission number set forth in the
Credit Agreement and shall be effective (a) in the case of mail, three days
after deposit in the postal system, first class postage pre-paid, and (b) in the
case of telex or facsimile notices, when sent if receipt is confirmed by
telephone. The Pledgor and any issuer of Pledged Stock may change their
respective addresses and transmission numbers by written notice to the
Administrative Agent.

                  17. IRREVOCABLE AUTHORIZATION AND INSTRUCTION TO ISSUERS. The
Pledgor hereby authorizes and instructs each issuer of Pledged Stock to comply
with any instruction received by it from the Administrative Agent in writing
that (a) states that an Event of Default has occurred and (b) is otherwise in
accordance with the terms of this Pledge Agreement, without any other or further
instructions from the Pledgor, and the Pledgor agrees that such issuer shall be
fully protected in so complying.

                  18. AUTHORITY OF AGENT. The Pledgor acknowledges that the
rights and responsibilities of the Administrative Agent under this Pledge
Agreement with respect to any action taken by the Administrative Agent or the
exercise or non-exercise by the Administrative Agent of any option, voting
right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Pledge Agreement shall, as between the
Administrative Agent

                                   9
<PAGE>

and the Lenders, be governed by the Credit Agreement and by such other
agreements with respect thereto as may exist from time to time among them,
but, as between the Administrative Agent and the Pledgor, the Administrative
Agent shall be conclusively presumed to be acting as agent for the Lenders
with full and valid authority so to act or refrain from acting, and neither
the Pledgor nor any issuer of Pledged Stock shall be under any obligation, or
entitlement, to make any inquiry respecting such authority.

                  19. TERMINATION; RELEASE. Upon the repayment of all the
Obligations in full and the termination of the Commitments, this Pledge
Agreement shall terminate, and the Administrative Agent, at the request of and
sole expense of the Pledgor, will execute and deliver to the Pledgor the proper
instruments (including Uniform Commercial Code termination statements on form
UCC-2 or UCC-3, as applicable) acknowledging the termination of this Pledge
Agreement, and will duly assign, transfer and deliver to the Pledgor (without
recourse and without any representation or warranty of any kind) such of the
Collateral as may be in the possession of the Administrative Agent and has not
theretofore been disposed of or otherwise applied or released.

                  20. COUNTERPARTS. This Pledge Agreement may be executed in
counterparts, and all of such counterparts taken together shall be deemed to
constitute one and the same instrument.

                                    10

                  IN WITNESS WHEREOF, the undersigned have caused this Pledge

                           to the capital stock of any Subsidiary of the Grantor

<PAGE>

adjudication of a court or other dispute resolution tribunal to be)
prohibited by the terms of such Contract.

                  3. RIGHTS OF ADMINISTRATIVE AGENT AND LENDERS; LIMITATIONS ON
ADMINISTRATIVE AGENT'S AND LENDERS' OBLIGATIONS.

                  (a) GRANTOR REMAINS LIABLE UNDER ACCOUNTS AND CONTRACTS.
Anything herein to the contrary notwithstanding, the Grantor shall remain liable
under each of the Accounts and Contracts to observe and perform all the
conditions and obligations to be observed and performed by it thereunder, all in
accordance with the terms of any agreement giving rise to each such Account and
in accordance with and pursuant to the terms and provisions of each such
Contract. Neither the Administrative Agent nor any Lender shall have any
obligation or liability under any Account (or any agreement giving rise thereto)
or under any Contract by reason of or arising out of this Security Agreement or
the receipt by the Administrative Agent or any such Lender of any payment
relating to such Account or Contract pursuant hereto, nor shall the
Administrative Agent or any Lender be obligated in any manner to perform any of
the obligations of the Grantor under or pursuant to any Account (or any
agreement giving rise thereto) or under or pursuant to any Contract, to make any
payment, to make any inquiry as to the nature or the sufficiency of any payment
received by it or as to the sufficiency of any performance by any party under
any Account (or any agreement giving rise thereto) or under any Contract, 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 it or to
which it may be entitled at any time or times.

                  (b) NOTICE TO ACCOUNT DEBTORS AND CONTRACTING PARTIES. At any
time after the occurrence and during the continuance of an Event of Default, the
Administrative Agent shall have the right at any time, upon written notice to
the Grantor of its intention to do so, to notify account debtors or obligors on
the Accounts and parties to the Contracts that the Accounts and the Contracts
have been assigned to the Administrative Agent for the ratable benefit of the
Lenders and that payments due or to become due to the Grantor in respect thereof
shall be made directly to the Administrative Agent and, upon such notification,
and at the expense of the Grantor, to enforce collection of any such Accounts.
The Administrative Agent may, at any time, in its own name or in the name of the
Lenders or the Grantor communicate with account debtors on the Accounts and
parties to the Contracts to verify with them to its satisfaction the existence,
amount and terms of any Accounts or Contracts. Unless an Event of Default shall
have occurred and be continuing, the Administrative Agent shall not exercise its
right under this clause (b) more than once in any 12-month period.

                  (c) COLLECTIONS ON ACCOUNTS. The Administrative Agent hereby
authorizes the Grantor to collect the Accounts; PROVIDED that the Administrative
Agent may curtail or terminate said authority at any time after the occurrence
of an Event of Default. If required by the Administrative Agent at any time
after the occurrence and during the continuance of an Event of Default, any
payments of Accounts, when collected by the Grantor, shall be forthwith (and, in
any event, within two Business Days) deposited by the Grantor in the exact form
received, duly endorsed by the Grantor to the Administrative Agent if required,
in a special collateral account maintained by the Administrative Agent, subject
to withdrawal by the Administrative Agent for the account of the Lenders only,
as hereinafter provided, and, until so turned over, shall be held


                                       4
<PAGE>

by the Grantor in trust for the Administrative Agent and the Lenders,
segregated from other funds of the Grantor. Each deposit of any such Proceeds
shall be accompanied by a report identifying in reasonable detail the nature
and source of the payments included in the deposit. All Proceeds constituting
collections of Accounts while held by the Administrative Agent (or by the
Grantor in trust for the Administrative Agent and the Lenders) shall continue
to be collateral security for all the Guarantee Obligations and shall not
constitute payment thereof until applied as hereinafter provided. At such
intervals as may be agreed upon by the Grantor and the Administrative Agent,
or, if an Event of Default shall have occurred and be continuing, at any time
at the Administrative Agent's election, the Administrative Agent shall apply
all or any part of the funds on deposit in said special collateral account on
account of the Guarantee Obligations in such order as the Administrative
Agent may elect, and any part of such funds which the Administrative Agent
elects not so to apply and deems not required as collateral security for the
obligations shall be paid over from time to time by the Administrative Agent
to the Grantor or to whomsoever may lawfully be entitled to receive the same
(it being understood that (i) prior to any Event of Default that is
continuing, the Grantor shall be permitted to use such funds in the operation
of its business in a manner consistent with the terms of the Credit Agreement
and (ii) within fifteen days after the occurrence of any Event of Default,
the Administrative Agent shall, in its sole discretion, either apply such
funds in payment of the Obligations in such order as the Administrative Agent
may elect or permit the Grantor to use such funds in the operation of its
business). Upon the occurrence of an Event of Default that is continuing, at
the Administrative Agent's request, the Grantor shall deliver to the
Administrative Agent all original and other documents evidencing, and
relating to, the agreements and transactions which gave rise to the Accounts,
including, without limitation, all original orders, invoices and shipping
receipts.

                  (d) ANALYSIS OF ACCOUNTS. The Administrative Agent shall have
the right to make test verifications of the Accounts in any manner and through
any medium that it reasonably considers advisable, and the Grantor shall furnish
all such assistance and information as the Administrative Agent may require in
connection therewith; PROVIDED that the Administrative Agent shall use its
reasonable efforts to minimize any disruption of the Grantor's business
resulting from such verifications. At any time and from time to time if the
Administrative Agent concludes in its reasonable judgment, based upon its
evaluation of the general creditworthiness of the Grantor, that such examination
is required, and so requests, the Grantor at its own expense shall cause
independent public accountants or other parties that are not Affiliates of the
Grantor and are reasonably satisfactory to the Administrative Agent to furnish
to the Administrative Agent reports showing reconciliations, aging and test
verifications of, and trial balances for, the Accounts. Unless an Event of
Default shall have occurred and be continuing, the Administrative Agent shall
not exercise its right under this clause (d) more than once in any 12-month
period.

                  4. REPRESENTATIONS AND WARRANTIES. The Grantor hereby
represents and warrants that:

                  (a) TITLE; NO OTHER LIENS. Except as permitted under Section
6.3 of the Credit Agreement, the Grantor owns or has a valid leasehold interest
in each item of the Collateral free and clear of any and all Liens or claims of
others. Except as permitted under Section 6.3(e) of the Credit Agreement, no
security agreement, financing statement or other public notice with


                                       5
<PAGE>

respect to all or any part of the Collateral is on file or of record in any
public office, except (i) such as may have been filed in favor of the
Administrative Agent, for the ratable benefit of the Lenders, pursuant to
this Security Agreement and (ii) financing statements filed by lessors solely
for information purposes in respect of "true" leases.

                  (b) PERFECTED FIRST PRIORITY LIENS. Except as permitted under
Section 6.3(e) of the Credit Agreement, the Liens granted pursuant to this
Security Agreement will, upon the filing of appropriate financing statements,
constitute valid and perfected first priority Liens on the Collateral in favor
of the Administrative Agent, for the ratable benefit of the Lenders, and against
any owner or purchaser of the real property where any of the Equipment is
located and any present or future creditor obtaining a Lien on such real
property, except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditor's rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

                  (c) ACCOUNTS. The amount represented by the Grantor to the
Lenders from time to time as owing by each account debtor or by all account
debtors in respect of the Accounts will at such time be the correct amount
actually owing by such account debtor or debtors thereunder. No amount payable
to the Grantor under or in connection with any Account is evidenced by any
Instrument or Chattel Paper which has not been delivered to the Administrative
Agent. The place where the Grantor keeps its records concerning the Accounts is
c/o Willis Stein & Partners, 227 West Monroe Street, Suite 4300, Chicago, IL
60606.

                  (d) CONTRACTS. Except as set forth in Schedule 3.4 to the
Credit Agreement, no consent of any party (other than the Grantor) to any
Contract is required in connection with the execution, delivery and performance
by the Grantor of this Security Agreement. Each Contract is in full force and
effect and constitutes a valid and legally enforceable obligation of the parties
thereto, except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditor's rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law). No consent or
authorization of, filing with or other act by or in respect of any Governmental
Authority is required in connection with the execution, delivery or performance
by the Grantor of, or the validity or enforceability of, any of the Contracts by
any party thereto other than those which have been duly obtained, made or
performed, are in full force and effect and do not subject the scope of any such
Contract to any material adverse limitation, either specific or general in
nature. Neither the Grantor nor (to the best of the Grantor's knowledge) any
other party to any Contract is in default in any material respect in the
performance or observance of any of the terms thereof. The Grantor has fully
performed in all material respects all its obligations under each Contract. The
right, title and interest of the Grantor in, to and under each Contract are not
subject to any defense, offset, counterclaim or claim which would materially
adversely affect the value of such Contract as Collateral, nor have any of the
foregoing been asserted or alleged against the Grantor as to any Contract. The
Grantor has delivered to the Administrative Agent a complete and correct copy of
each material Contract, including all amendments, supplements and other
modifications thereto and will deliver any other Contract which the
Administrative Agent may request. No amount payable to the Grantor under or in
connection with any Contract is evidenced by any Instrument or Chattel Paper
which has not been delivered to the Administrative Agent.

                  (e) INVENTORY AND EQUIPMENT. The Inventory and the Equipment
are kept at the locations listed on Schedule I hereto.

                  (f) CHIEF EXECUTIVE OFFICE. The Grantor's chief executive
office and chief place of business is located at c/o Willis Stein & Partners,
227 West Monroe Street, Suite 4300, Chicago, IL 60606.

                  (g) FARM PRODUCTS. None of the Collateral constitutes, or is
the Proceeds of, Farm Products.

                  (h) GOVERNMENTAL OBLIGORS. None of the obligors on any
Accounts, and none of the parties to any Contracts, is a Governmental Authority.

                  (i) INVESTMENT PROPERTY. The Investment Property consists of
the items set forth on Annex A.

                  5. COVENANTS. The Grantor covenants and agrees with the
Administrative Agent and the Lenders that, from and after the date of this
Security Agreement until the Obligations are paid in full and the Commitments
are terminated:

                  (a) FURTHER DOCUMENTATION; PLEDGE OF INSTRUMENTS AND CHATTEL
PAPER. At any time and from time to time, upon the written request of the
Administrative Agent, and at the sole expense of the Grantor, the Grantor will
promptly and duly execute and deliver such further instruments and documents and
take such further action as the Administrative Agent may reasonably request for
the purpose of obtaining or preserving the full benefits of this Security
Agreement and of the rights and powers herein granted, including, without
limitation, the filing of any financing or continuation statements under the
Uniform Commercial Code in effect in any jurisdiction with respect to the Liens
created hereby. The Grantor also hereby authorizes the Administrative Agent to
file any such financing or continuation statement without the signature of the
Grantor to the extent permitted by applicable law. A carbon, photographic or
other reproduction of this Security Agreement shall be sufficient as a financing
statement for filing in any jurisdiction. If any amount payable under or in
connection with any of the Collateral shall be or become evidenced by any
Instrument or Chattel Paper, such Instrument or Chattel Paper shall be
immediately delivered to the Administrative Agent, duly endorsed in a manner
satisfactory to the Administrative Agent, to be held as Collateral pursuant to
this Security Agreement.

                  (b) INDEMNIFICATION. The Grantor agrees to pay, and to save
the Administrative Agent and the Lenders harmless from, any and all liabilities,
costs and expenses (including, without limitation, legal fees and expenses) (i)
with respect to, or resulting from, any delay in paying any and all excise,
sales or other taxes which may be payable or determined to be payable with
respect to any of the Collateral, (ii) with respect to, or resulting from, any
delay in complying with any Requirement of Law applicable to any of the
Collateral or (iii) in connection with any of the transactions contemplated by
this Security Agreement, except resulting from the Administrative Agent's or any
Lender's gross negligence or willful misconduct. In any suit, proceeding or
action brought by the Administrative Agent or any Lender under any Account or
Contract for any sum owing thereunder, or to enforce any provisions of any
Account or Contract,


                                       7
<PAGE>

the Grantor will save, indemnify and keep the Administrative Agent and such
Lender harmless from and against all expense, loss or damage suffered by
reason of any defense, setoff, counterclaim, recoupment or reduction or
liability whatsoever of the account debtor or obligor thereunder, arising out
of a breach by the Grantor of any obligation thereunder or arising out of any
other agreement, indebtedness or liability at any time owing to or in favor
of such account debtor or obligor or its successors from the Grantor, except
resulting from the Administrative Agent's or any Lender's gross negligence or
willful misconduct.

                  (c) MAINTENANCE OF RECORDS. The Grantor will keep and maintain
at its own cost and expense satisfactory and complete records of the Collateral,
including, without limitation, a record of all payments received and all credits
granted with respect to the Accounts. The Grantor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby in such manner as the Administrative Agent may
request. For the Administrative Agent's and the Lenders' further security, the
Administrative Agent, for the ratable benefit of the Lenders, shall have a
security interest in all the Grantor's books and records pertaining to the
Collateral, and the Grantor shall, during the continuance of a Default under
Section 7.1(a) of the Credit Agreement or Section 7.1(c) of the Credit Agreement
as it relates to Section 6.1 of the Credit Agreement, turn over copies of such
books and records and during the continuation of an Event of Default turn over
any such books and records, in each case, to the Administrative Agent or to its
representatives at the request of the Administrative Agent.

                  (d) RIGHT OF INSPECTION. The Administrative Agent and the
Lenders shall at all times have full and free access during normal business
hours and, so long as no Event of Default shall have occurred and be continuing,
upon reasonable prior notice, to all books, correspondence and records of the
Grantor, and the Administrative Agent and the Lenders and their respective
representatives may examine the same, take extracts therefrom and make
photocopies thereof, and the Grantor agrees to render to the Administrative
Agent and the Lenders, at the Grantor's cost and expense, such clerical and
other assistance as may be reasonably requested with regard thereto. The
Administrative Agent and the Lenders and their respective representatives shall
at all times and, so long as no Event of Default shall have occurred and be
continuing, upon reasonable prior notice, also have the right to enter into and
upon any premises where any of the Inventory or Equipment is located for the
purpose of inspecting the same, observing its use or otherwise protecting its
interests therein.

                  (e) COMPLIANCE WITH LAWS. The Grantor will comply in all
material respects with all Requirements of Law applicable to the Collateral or
any part thereof or to the operation of the Grantor's business; PROVIDED that
the Grantor may contest any Requirement of Law in any reasonable manner which
shall not, in the sole opinion of the Administrative Agent, adversely affect the
Administrative Agent's or the Lenders' rights or the priority of their Liens on
the Collateral.

                  (f) COMPLIANCE WITH TERMS OF CONTRACTS. The Grantor will
perform and comply in all material respects with all its obligations under the
Contracts and all its other Contractual Obligations relating to the Collateral.

                  (g) PAYMENT OF OBLIGATIONS. The Grantor will pay promptly when
due all taxes, assessments and governmental charges or levies imposed upon the
Collateral or in respect of its income or profits therefrom, as well as all
claims of any kind (including, without limitation, claims for labor, materials
and supplies) against or with respect to the Collateral, except that no such
charge need be paid if (i) the validity thereof is being contested in good faith
by appropriate proceedings, (ii) such proceedings do not involve any material
danger of the sale, forfeiture or loss of any of the Collateral or any interest
therein and (iii) such charge is adequately reserved against on the Grantor's
books in accordance with GAAP.

                  (h) LIMITATION ON LIENS ON COLLATERAL. The Grantor will not
create, incur or permit to exist, will defend the Collateral against, and will
take such other action as is necessary to remove, any Lien or claim on or to the
Collateral, other than the Liens created hereby and other than as permitted
pursuant to Section 6.3 of the Credit Agreement, and will defend the right,
title and interest of the Administrative Agent and the Lenders in and to any of
the Collateral against the claims and demands of all Persons whomsoever.

                  (i) LIMITATIONS ON DISPOSITIONS OF COLLATERAL. The Grantor
will not sell, transfer, lease or otherwise dispose of any of the Collateral, or
attempt, offer or contract to do so except as permitted pursuant to Section 6.6
of the Credit Agreement.

                  (j) LIMITATIONS ON MODIFICATIONS, WAIVERS, EXTENSIONS OF
CONTRACTS AND AGREEMENTS GIVING RISE TO ACCOUNTS. Subject to subsection (k)
below, the Grantor will not (i) amend, modify, terminate or waive any provision
of any Material Contract or any agreement giving rise to an Account in any
manner which could reasonably be expected to materially adversely affect the
value of such Contract or Account as Collateral, (ii) fail to exercise promptly
and diligently each and every material right which it may have under each
Contract and each agreement giving rise to an Account (other than any right of
termination) or (iii) fail to deliver to the Administrative Agent a copy of each
material demand, notice or document received by it relating in any way to any
Contract or any agreement giving rise to an Account. As used in this clause (j),
a "Material Contract" shall mean any contract with a stated duration (including
any extension periods contained therein) of more than 12 months and with a value
of more than $750,000.

                  (k) LIMITATIONS ON DISCOUNTS, COMPROMISES, EXTENSIONS OF
ACCOUNTS. Other than in the ordinary course of business, the Grantor will not
grant any extension of the time of payment of any of the Accounts, compromise,
compound or settle the same for less than the full amount thereof, release,
wholly or partially, any Person liable for the payment thereof, or allow any
credit or discount whatsoever thereon.

                  (l) MAINTENANCE OF EQUIPMENT. The Grantor will maintain each
item of Equipment not subject to Section 6.6(a) of the Credit Agreement in good
operating condition, ordinary wear and tear and immaterial impairments of value
and damage by the elements excepted, and will provide all maintenance, service
and repairs necessary for such purpose.

                  (m) MAINTENANCE OF INSURANCE. The Grantor will maintain, with
financially sound and reputable companies, insurance policies as required under
the Credit Agreement. All such policies shall (i) contain a breach of warranty
clause in favor of the Administrative Agent


                                       9
<PAGE>

and the Lenders, (ii) provide that no cancellation, material reduction in
amount or material change in coverage thereof shall be effective until at
least 30 days after receipt by the Administrative Agent and the Lenders of
written notice thereof, (iii) name the Administrative Agent as loss payee of
each such policy, (iv) name the Administrative Agent and the Lenders as
insured to the extent of their interests under each such policy and (v) be
reasonably satisfactory in all material respects to the Administrative Agent.
The Grantor shall deliver to the Administrative Agent and each Lender upon
request, full information as to the insurance carried, including certified
copies of policies and certificates of insurance from a recognized insurance
broker reasonably acceptable to the Administrative Agent.

                  (n) FURTHER IDENTIFICATION OF COLLATERAL. The Grantor will
furnish to the Administrative Agent and the Lenders from time to time statements
and schedules further identifying and describing the Collateral and such other
reports in connection with the Collateral as the Administrative Agent may
reasonably request, all in reasonable detail.

                  (o) NOTICES. The Grantor will advise the Administrative Agent
promptly, in reasonable detail, at its address set forth in the Credit
Agreement, (i) of any Lien (other than Liens created hereby or permitted under
the Credit Agreement) on, or claim asserted against, any of the Collateral and
(ii) of the occurrence of any other event which could reasonably be expected to
have a material adverse effect on the aggregate value of the Collateral or on
the Liens created hereunder.

                  (p) CHANGES IN LOCATIONS, NAME, ETC. Unless the Grantor gives
30 days' prior written notice to the Administrative Agent, the Grantor will not
(i) change the location of its chief executive office/chief place of business
from that specified in Section 4(f) or remove its books and records from the
location specified in Section 4(c), (ii) permit any of the Inventory or
Equipment to be kept at a location other than those listed on Schedule I hereto
or (iii) change its name, identity or corporate structure to such an extent that
any financing statement filed by the Administrative Agent in connection with
this Security Agreement would become seriously misleading.

                  6. ADMINISTRATIVE AGENT'S APPOINTMENT AS ATTORNEY-IN-FACT.

                  (a) POWERS. The Grantor hereby irrevocably constitutes and
appoints the Administrative Agent and any officer or agent thereof, with full
power of substitution, as its true and lawful attorney-in-fact with full
irrevocable power and authority in the place and stead of the Grantor and in the
name of the Grantor or in its own name, from time to time in the Administrative
Agent's discretion, for the purpose of carrying out the terms of this Security
Agreement, to take any and all appropriate action and to execute any and all
documents and instruments which may be necessary or desirable to accomplish the
purposes of this Security Agreement, and, without limiting the generality of the
foregoing, the Grantor hereby gives the Administrative Agent the power and
right, on behalf of the Grantor, without notice to or assent by the Grantor, to
do the following:

                  (i) in the case of any Account, at any time when the authority
         of the Grantor to collect the Accounts has been curtailed or terminated
         pursuant to the first sentence of Section 3(c), or in the case of any
         other Collateral, at any time when any Event of Default


                                       10

         shall have occurred and is continuing, in the name of the Grantor or
         its own name, or otherwise, to take possession of and endorse and
         collect any checks, drafts, notes, acceptances or other instruments
         for the payment of moneys due under any Account, Instrument, General
         Intangible or Contract or with respect to any other Collateral and
         to file any claim or to take any other action or proceeding in any
         court of law or equity or otherwise deemed appropriate by the
         Administrative Agent for the purpose of collecting any and all such
         moneys due under any Account, Instrument, General Intangible or
         Contract or with respect to any other Collateral whenever payable;

                  (ii) to pay or discharge taxes and Liens levied or placed on
         or threatened against the Collateral, to effect any repairs or any
         insurance called for by the terms of this Security Agreement and to pay
         all or any part of the premiums therefor and the costs thereof; and

                  (iii) upon the occurrence and during the continuance of any
         Event of Default, (A) to direct any party liable for any payment under
         any of the Collateral to make payment of any and all moneys due or to
         become due thereunder directly to the Administrative Agent or as the
         Administrative Agent shall direct; (B) to ask or demand for, collect,
         receive payment of and receipt for, any and all moneys, claims and
         other amounts due or to become due at any time in respect of or arising
         out of any Collateral; (C) to sign and endorse any invoices, freight or
         express bills, bills of lading, storage or warehouse receipts, drafts
         against debtors, assignments, verifications, notices and other
         documents in connection with any of the Collateral; (D) to commence and
         prosecute any suits, actions or proceedings at law or in equity in any
         court of competent jurisdiction to collect the Collateral or any
         thereof and to enforce any other right in respect of any Collateral;
         (E) to defend any suit, action or proceeding brought against the
         Grantor with respect to any Collateral; (F) to settle, compromise or
         adjust any suit, action or proceeding described in clause (E) above
         and, in connection therewith, to give such discharges or releases as
         the Administrative Agent may deem appropriate; and (G) generally, to
         sell, transfer, pledge and make any agreement with respect to or
         otherwise deal with any of the Collateral as fully and completely as
         though the Administrative Agent were the absolute owner thereof for all
         purposes, and to do, at the Administrative Agent's option and the
         Grantor's expense, at any time, or from time to time, all acts and
         things which the Administrative Agent deems necessary to protect,
         preserve or realize upon the Collateral and the Administrative Agent's
         and the Lenders' Liens thereon and to effect the intent of this
         Security Agreement, all as fully and effectively as the Grantor might
         do.

The Grantor 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 shall be irrevocable.

                  (b) OTHER POWERS. The Grantor also authorizes the
Administrative Agent and the Lenders, at any time and from time to time, to
execute, in connection with the sale provided for in this SECTION 6 or in
SECTION 9 hereof, any endorsements, assignments or other instruments of
conveyance or transfer with respect to the Collateral.

                  (c) NO DUTY ON ADMINISTRATIVE AGENT'S OR LENDERS' PART. The
powers conferred on the Administrative Agent and the Lenders hereunder are
solely to protect the


                                       11
<PAGE>

Administrative Agent's and the Lenders' interests in the Collateral and shall
not impose any duty upon the Administrative Agent or any Lender to exercise
any such powers. The Administrative Agent and the Lenders shall be
accountable only for amounts that they actually receive as a result of the
exercise of such powers, and neither they nor any of their officers,
directors, employees or agents shall be responsible to the Grantor for any
act or failure to act hereunder, except for their own gross negligence or
willful misconduct.

                  7. PERFORMANCE BY ADMINISTRATIVE AGENT OF GRANTOR'S
OBLIGATIONS. If the Grantor fails to perform or comply with any of its
agreements contained herein and the Administrative Agent, as provided for by the
terms of this Security Agreement, shall itself perform or comply, or otherwise
cause performance or compliance, with such agreement, the expenses of the
Administrative Agent incurred in connection with such performance or compliance,
together with interest thereon at a rate per annum 2% above the Alternate Base
Rate, shall be payable by the Grantor to the Administrative Agent on demand and
shall constitute Guarantee Obligations secured hereby.

                  8. PROCEEDS. In addition to the rights of the Administrative
Agent and the Lenders specified in Section 3(c) with respect to payments of
Accounts, it is agreed that if an Event of Default shall occur and be continuing
(a) upon written notice by the Administrative Agent to the Grantor, all Proceeds
received by the Grantor consisting of cash, checks and other near-cash items
shall be held by the Grantor in trust for the Administrative Agent and the
Lenders, segregated from other funds of the Grantor, and, forthwith upon receipt
by the Grantor, shall be turned over to the Administrative Agent in the exact
form received by the Grantor (duly endorsed by the Grantor to the Administrative
Agent, if required), and (b) any and all such Proceeds received by the
Administrative Agent (whether from the Grantor or otherwise) may, in the sole
discretion of the Administrative Agent, (i) be held by the Administrative Agent
for the ratable benefit of the Lenders as collateral security for the Guaranteed
Obligations, and/or (ii) then or at any time thereafter either (x) be applied by
the Administrative Agent for the ratable benefit of the Lenders against the
Guarantee Obligations (whether matured or unmatured), such application to be in
such order as the Administrative Agent shall elect, or (y) at the sole
discretion of the Administrative Agent, be available for use by the Grantor in
the operation of its business. Any balance of such Proceeds remaining after the
Guarantee Obligations shall have been paid in full and the Commitments shall
have been terminated shall be paid over to the Grantor or to whomsoever may be
lawfully entitled to receive the same.

                  9. REMEDIES. If an Event of Default shall occur and be
continuing, the Administrative Agent, on behalf of the Lenders, may exercise, in
addition to all other rights and remedies granted to them in this Security
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Guarantee Obligations, all rights and remedies of a secured
party under the Code. Without limiting the generality of the foregoing, the
Administrative Agent, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law referred to below) to or upon the Grantor, any guarantor, or any
other Person (all and each of which demands, defenses, advertisements and
notices being hereby waived to the maximum extent permitted by applicable law),
may in such circumstances forthwith collect, receive, appropriate and realize
upon the Collateral, or any part thereof, and/or may forthwith sell, lease,
assign, give option or options to purchase, or otherwise dispose of and deliver
the Collateral or any part thereof (or contract to do


                                       12
<PAGE>

any of the foregoing), in one or more parcels at public or private sale or
sales, at any exchange, broker's board or office of the Administrative Agent
or any Lender or elsewhere upon such terms and conditions as it may deem
advisable and at such prices as it may deem best, for cash or on credit or
for future delivery without assumption of any credit risk. The Administrative
Agent or any Lender shall have the right upon any such public sale or sales,
and, to the extent permitted by applicable law, upon any such private sale or
sales, to purchase the whole or any part of the Collateral so sold, free of
any right or equity of redemption in the Grantor, which right or equity is
hereby waived or released to the maximum extent permitted by applicable law.
The Grantor further agrees, at the Administrative Agent's request, to
assemble the Collateral and make it available to the Administrative Agent at
such places as the Administrative Agent shall reasonably select, whether at
the Grantor's premises or elsewhere. The Administrative Agent shall apply the
net proceeds of any such collection, recovery, receipt, appropriation,
realization or sale, after deducting all reasonable costs and expenses of
every kind incurred therein or incidental to the care or safekeeping of any
of the Collateral or in any way relating to the Collateral or the rights of
the Administrative Agent and the Lenders hereunder, including, without
limitation, reasonable attorneys' fees and disbursements, to the payment in
whole or in part of the Guarantee Obligations, in such order as the
Administrative Agent may elect, and only after such application and after the
payment by the Administrative Agent of any other amount required by any
provision of law, including, without limitation, Section 9-504(i)(c) of the
Code, need the Administrative Agent account for the surplus, if any, to the
Grantor. To the extent permitted by applicable law, the Grantor waives all
claims, damages and demands it may acquire against the Administrative Agent
or any Lender arising out of the exercise by them of any rights hereunder. If
any notice of a proposed sale or other disposition of Collateral shall be
required by law, such notice shall be deemed reasonable and proper if given
at least 10 days before such sale or other disposition. The Grantor shall
remain liable for any deficiency if the proceeds of any sale or other
disposition of the Collateral are insufficient to pay the Guarantee
Obligations and the fees and disbursements of any attorneys employed by the
Administrative Agent or any Lender to collect such deficiency.

                  10. LIMITATION ON DUTIES REGARDING PRESERVATION OF COLLATERAL.
The Administrative Agent's sole duty with respect to the custody, safekeeping
and physical preservation of the Collateral in its possession, under Section
9-207 of the Code or otherwise, shall be to deal with it in the same manner as
the Administrative Agent deals with similar property for its own account.
Neither the Administrative Agent, any Lender, nor any of their respective
directors, officers, employees or agents shall be liable for failure to demand,
collect or realize upon all or any part of the Collateral or for any delay in
doing so or shall be under any obligation to sell or otherwise dispose of any
Collateral upon the request of the Grantor or otherwise.

                  11. POWERS COUPLED WITH AN INTEREST. All authorizations and
agencies herein contained with respect to the Collateral are irrevocable and
powers coupled with an interest.

                  12. LIMITATION ON LINES OF BUSINESS. Nothing in this Security
Agreement shall be deemed or construed as modifying in any way the restrictions
on the Grantor's activities as set forth in Section 6.14 of the Credit
Agreement.


                                       13
<PAGE>

                  13. SEVERABILITY. Any provision of this Security Agreement
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

                  14. SECTION HEADINGS. The section headings used in this
Security Agreement are for convenience of reference only and are not to affect
the construction hereof or be taken into consideration in the interpretation
hereof.

                  15. NO WAIVER; CUMULATIVE REMEDIES. Neither the Administrative
Agent nor any Lender shall by any act (except by a written instrument pursuant
to SECTION 16), delay, indulgence, omission or otherwise be deemed to have
waived any right or remedy hereunder or to have acquiesced in any Default or
Event of Default or in any breach of any of the terms and conditions hereof. No
failure to exercise, nor any delay in exercising, on the part of the
Administrative Agent or any Lender, any right, power or privilege hereunder
shall operate as a waiver thereof. No single or partial exercise of any right,
power or privilege hereunder shall preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. A waiver by the
Administrative Agent or any Lender of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy which the
Administrative Agent or such Lender would otherwise have on any future occasion.
The rights and remedies herein provided are cumulative, may be exercised singly
or concurrently and are not exclusive of any rights or remedies provided by law.

                  16. WAIVERS AND AMENDMENTS; SUCCESSORS AND ASSIGNS. None of
the terms or provisions of this Security Agreement may be waived, amended,
supplemented or otherwise modified except by a written instrument executed by
the Grantor and the Administrative Agent; PROVIDED that any provision of this
Security Agreement may be waived by the Administrative Agent in a written letter
or agreement executed by the Administrative Agent or by telex or facsimile
transmission from the Administrative Agent. This Security Agreement shall be
binding upon the successors and assigns of the Grantor and shall inure to the
benefit of the Administrative Agent and the Lenders and their respective
successors and assigns.

                  17. GOVERNING LAW. THIS SECURITY AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS SECURITY AGREEMENT SHALL BE GOVERNED BY,
AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW
YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS THEREOF OTHER THAN
SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK, EXCEPT
FOR PERFECTION AND ENFORCEMENT OF SECURITY INTERESTS AND LIENS IN OTHER
JURISDICTIONS TO THE EXTENT THE LAW OF ANOTHER JURISDICTION IS MANDATORILY
APPLICABLE PURSUANT TO THE LAWS OF SUCH JURISDICTION.

                  18. NOTICES. Notices hereunder may be given by mail, by telex
or by facsimile transmission, addressed or transmitted to the Person to which it
is being given at such Person's address or transmission number set forth in the
Credit Agreement and shall be effective (a) in the case of mail, three days
after deposit in the postal system, first class postage pre-paid and (b) in


                                       14
<PAGE>

the case of telex or facsimile notices, when sent if receipt is confirmed by
telephone. The Grantor may change its address and transmission number by
written notice to the Administrative Agent, and the Administrative Agent or
any Lender may change its address and transmission number by written notice
to the Grantor and, in the case of any Lender, to the Administrative Agent.

                  19. AUTHORITY OF ADMINISTRATIVE AGENT. The Grantor
acknowledges that the rights and responsibilities of the Administrative Agent
under this Security Agreement with respect to any action taken by the
Administrative Agent or the exercise or non-exercise by the Administrative Agent
of any option, right, request, judgment or other right or remedy provided for
herein or resulting or arising out of this Security Agreement shall, as between
the Administrative Agent and the Lenders, be governed by the Credit Agreement
and by such other agreements with respect thereto as may exist from time to time
among them, but, as between the Administrative Agent and the Grantor, the
Administrative Agent shall be conclusively presumed to be acting as agent for
the Lenders with full and valid authority so to act or refrain from acting, and
the Grantor shall not be under any obligation, or entitlement, to make any
inquiry respecting such authority.

                  20. COUNTERPARTS. This Security Agreement may be executed in
counterparts, and all of such counterparts taken together shall be deemed to
constitute one and the same instrument.

         any Hedging Agreement entered into with any Agent, any Lender or any of
         their respective Affiliates, whether direct or indirect, absolute or
         contingent, due or to become due, now existing or hereafter incurred,
         which may arise under, out of, or in connection with, the Credit
         Agreement, the Notes, the other Loan Documents or any Hedging Agreement
         with any Agent, any Lender or any of their respective Affiliates or any
         other document made, delivered or given in connection therewith or

         obligations, fees, indemnities, costs, expenses (including, without

<PAGE>


         applicable, pursuant to the terms of the Credit Agreement, any other
         Loan Document or any Hedging Agreement with any Agent, any Lender or
         any of their respective Affiliates) or otherwise.

                  2. GUARANTEE. (a) The Guarantor hereby unconditionally and
irrevocably guarantees to the Administrative Agent and the Lenders and their
respective successors, endorsees, transferees and assigns, the prompt and
complete payment by the Borrower when due (whether at the stated maturity, by
acceleration or otherwise) of the Obligations, and the Guarantor further agrees
to pay any and all expenses (including, without limitation, all fees and
disbursements of counsel) which may be paid or incurred by the Administrative
Agent or any Lender in enforcing, or obtaining advice of counsel in respect of,
any rights with respect to, or collecting, any or all the Obligations and/or
enforcing any rights with respect to, or collecting against, the Guarantor under
this Guarantee; PROVIDED, that the obligations of the Guarantor hereunder shall
be limited to an aggregate amount equal to the largest amount that would not
render its obligations hereunder subject to avoidance under Section 548 of the
United States Bankruptcy Code or any comparable provisions of any applicable
state law.

                           (b) No payment or payments made by the Borrower, any
other guarantor or any other Person or received or collected by the
Administrative Agent or any Lender from the Borrower, any other guarantor or any
other Person by virtue of any action or proceeding or any setoff or
appropriation or application at any time or from time to time in reduction of or
in payment of the Obligations shall be deemed to modify, reduce, release or
otherwise affect the liability of the Guarantor hereunder which shall,
notwithstanding any such payment or payments other than payments made by the
Guarantor in respect of the Obligations or payments received or collected from
the Guarantor in respect of the Obligations, remain liable for the Obligations
until the Obligations are paid in full and the Commitments are terminated.

                           (c) The Guarantor agrees that whenever, at any time,
or from time to time, it shall make any payment to the Administrative Agent or
any Lender on account of its liability hereunder, it will notify the
Administrative Agent in writing that such payment is made under this Guarantee
for such purpose.

                           3. RIGHT OF SETOFF. Upon the occurrence of any Event
of Default specified in the Credit Agreement, the Guarantor hereby irrevocably
authorizes the Administrative Agent at each Lender at any time and from time to
time without notice to the Guarantor or any other guarantor, any such notice
being expressly waived by the Guarantor, to setoff and appropriate and apply any
and all deposits (general or special, time or demand, provisional or final), in
any currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by the Administrative Agent and/or such
Lender to or for the credit or the account of the Guarantor, or any part thereof
in such amounts as the Administrative Agent or such may elect, against and on
account of the obligations and liabilities of the Guarantor to the
Administrative Agent or such Lender hereunder and claims of every nature and
description of the Administrative Agent or such Lender against the Guarantor, in
any currency, whether arising hereunder, under the Credit Agreement, the Notes,
the Security Documents, any other Loan Document, any Hedging Agreement with
either Agent, any Lender or any of their respective Affiliates or otherwise, as
the Administrative Agent or such Lender may elect, whether or not the
Administrative Agent or


                                       3
<PAGE>


any Lender has made any demand for payment and although such obligations,
liabilities and claims may be contingent or unmatured. The Administrative
Agent and each Lender agrees to notify the Guarantor promptly of any such
setoff and the application made by the Administrative Agent or such Lender;
PROVIDED that the failure to give such notice shall not affect the validity
of such setoff and application. The rights of the Administrative Agent and
each Lender under this paragraph are in addition to other rights and remedies
(including, without limitation, other rights of setoff) which the
Administrative Agent or such Lender may have.

                           4. NO SUBROGATION. Notwithstanding any payment or
payments made by the Guarantor hereunder or any setoff or application of funds
of the Guarantor by the Administrative Agent or any Lender, until all
Obligations have been irrevocably and indefeasibly paid in full in cash (and
therefore the payment thereof is no longer subject to being set aside or
returned under applicable law), the Guarantor hereby waives any claim, right or
remedy which the Guarantor may now have or may hereafter acquire against the
Borrower that arises hereunder and/or from the performance by the Guarantor
hereunder including, without limitation, any claim, remedy or right of
subrogation, reimbursement, exoneration, contribution, indemnification or
participation in any claim, right or remedy of the Lenders and the
Administrative Agent against the Borrower or any security which the Lenders and
the Administrative Agent now have or hereafter acquire, whether or not such
claim, right or remedy arises in equity, under contract, by statute, under
common law or otherwise; PROVIDED that if the foregoing standstill is not
sufficient to permit indefeasible payment in full of all the Obligations, then
the Guarantor shall be deemed to have waived any such claim, right or remedy to
the maximum extent permitted by law. If any amount shall be paid to the
Guarantor on account of such subrogation rights at any time when all the
Obligations shall not have been paid in full, such amount shall be held by the
Guarantor in trust for the Administrative Agent and the Lenders, segregated from
other funds of the Guarantor, and shall, forthwith upon receipt by the
Guarantor, be turned over to the Administrative Agent in the exact form received
by the Guarantor (duly endorsed by the Guarantor to the Administrative Agent, if
required), to be applied against the Obligations, whether matured or unmatured,
in such order as the Administrative Agent may determine.

                           5. AMENDMENTS, ETC, WITH RESPECT TO THE OBLIGATIONS:
WAIVER OF RIGHTS. The Guarantor shall remain obligated hereunder notwithstanding
that, without any reservation of rights against the Guarantor and without notice
to or further assent by the Guarantor, any demand for payment of any of the
Obligations made by the Administrative Agent or any Lender may be rescinded by
such party and any of the Obligations continued, and the Obligations, or the
liability of any other party upon or for any part thereof, or any collateral
security or guarantee therefor or right of offset with respect thereto, may,
from time to time, in whole or in part, be renewed, extended, amended, modified,
accelerated, compromised, waived, surrendered or released, in accordance with
the terms of such agreement, by the Administrative Agent or any Lender and the
Credit Agreement, the Notes, the Security Documents, the other Loan Documents,
any Hedging Agreement with either Agent or Lender and any other collateral
security document or other guarantee or document in connection therewith may be
amended, modified, supplemented or terminated, in whole or in part, in
accordance with the terms of such agreement, as the Administrative Agent and/or
any Lender may deem advisable from time to time, and any collateral security,
guarantee or right of offset at any time held by the Administrative Agent or any
Lender for the payment of the Obligations may be sold, exchanged, waived,
surrendered or released. Neither the Administrative Agent nor any Lender shall
have


                                       4
<PAGE>


any obligation to protect, secure, perfect or insure any Lien at any time
held as security for the Obligations or for this Guarantee or any property
subject thereto. When making any demand hereunder against the Guarantor, the
Administrative Agent or any Lender may, but shall be under no obligation to,
make a similar demand on the Borrower or any other guarantor, and any failure by
the Administrative Agent or any Lender to make any such demand or to collect any
payments from the Borrower or any such other guarantor or any release of the
Borrower or such other guarantor shall not relieve the Guarantor of its
obligations or liabilities hereunder, and shall not impair or affect the rights
and remedies, express or implied, or as a matter of law, of the Administrative
Agent against the Guarantor. For the purposes hereof, "demand" shall include the
commencement and continuance of any legal proceedings.

                           6. GUARANTEE ABSOLUTE AND UNCONDITIONAL. The
Guarantor waives any and all notice of the creation, renewal, extension or
accrual of any of the Obligations and notice of or proof of reliance by the
Administrative Agent or any Lender upon this Guarantee or acceptance of this
Guarantee, the Obligations, and any of them, shall conclusively be deemed to
have been created, contracted or incurred, or renewed, extended, amended or
waived, in reliance upon this Guarantee; and all dealings between the Borrower
or the Guarantor and the Administrative Agent or any Lender shall likewise be
conclusively presumed to have been had or consummated in reliance upon this
Guarantee. The Guarantor waives diligence, presentment, protest, demand for
payment and notice of default or nonpayment to or upon the Borrower or the
Guarantor with respect to the Obligations. The Guarantor understands and agrees
that this Guarantee shall be construed as a continuing, absolute and
unconditional guarantee of payment without regard to (a) the validity,
regularity or enforceability of the Credit Agreement, the Notes, any of the
Security Documents, any other Loan Document, any of the obligations or any other
collateral security therefor or guarantee or right of offset with respect
thereto at any time or from time to time held by the Administrative Agent or any
Lender, (b) any defense, setoff or counterclaim (other than a defense of payment
or performance) which may at any time be available to or be asserted by the
Borrower against Administrative Agent or any Lender, or (c) any other
circumstance whatsoever (with or without notice to or knowledge of the Borrower
or the Guarantor) which constitutes, or might be construed to constitute, an
equitable or legal discharge of the Borrower for the Obligations, or of the
Guarantor under this Guarantee, in bankruptcy or in any other instance. When
pursuing its rights and remedies hereunder against the Guarantor, the
Administrative Agent and any Lender may, but shall be under no obligation to,
pursue such rights and remedies as it may have against the Borrower or any other
Person or against any collateral security or guarantee for the obligations or
any right of offset with respect thereto, and any failure by the Administrative
Agent or any Lender to pursue such other rights or remedies or to collect any
payments from the Borrower or any such other Person or to realize upon any such
collateral security or guarantee or to exercise any such right of offset, or any
release of the Borrower or any such other Person or any such collateral
security, guarantee or right of offset, shall not relieve the Guarantor of any
liability hereunder, and shall not impair or affect the rights and remedies,
whether express, implied or available as a matter of law, of the Administrative
Agent or any Lender against the Guarantor. This Guarantee shall remain in full
force and effect and be binding in accordance with and to the extent of its
terms upon the Guarantor and the successors and assigns thereof, and shall inure
to the benefit of the Administrative Agent and the Lenders, and its respective
successors, endorsees, transferees and assigns, until all the Obligations and
the obligations of the Guarantor under this Guarantee shall have been satisfied
by payment in full


                                       5
<PAGE>


and the Commitments shall be terminated, notwithstanding that from time to
time during the term of the Credit Agreement the Borrower may be free from
any Obligations.

                  7. REINSTATEMENT. This Guarantee shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any of the Obligations is rescinded or must otherwise be
restored or returned by the Administrative Agent or any Lender upon the
insolvency, bankruptcy, dissolution, liquidation or reorganization of the
Borrower or the Guarantor, or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
Borrower or the Guarantor or any substantial part of its property, or otherwise,
all as though such payments had not been made.

                  8. PAYMENTS. The Guarantor hereby guarantees that payments
hereunder will be paid to the Administrative Agent for the benefit or the
Lenders without setoff or counterclaim in U.S. Dollars at the office of the
Administrative Agent located at 425 Lexington Avenue, New York, New York 10017
or such other location as the Administrative Agent may from time to time direct
the Guarantor.

                  9. REPRESENTATIONS AND WARRANTIES. The Guarantor hereby
represents and warrants that:

                           (a) the Guarantor has the corporate power and
authority, and the legal right, to execute, deliver and perform its obligations
under, this Guarantee and the other Loan Documents to which the Guarantor is a
party, and has taken all necessary corporate action to authorize the execution,
delivery and performance of this Guarantee and the other Loan Documents to which
the Guarantor is a party;

                           (b) this Guarantee and the other Loan Documents to
which the Guarantor is a party each constitute a legal, valid and binding
obligation of the Guarantor enforceable in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting the enforcement of creditors, rights
generally or by general principles of equity (whether enforcement is sought by
proceedings in equity or at law);

                           (c) the execution, delivery and performance by the
Guarantor of this Guarantee or any other Loan Document to which the Guarantor is
a party will not violate any Requirement of Law or Contractual Obligation of the
Guarantor, except for such violations which could not reasonably be expected to
result in liability in excess of $500,000 in the aggregate, and will not result
in, or require, the creation or imposition of any Lien on any of the properties
or revenues of the Guarantor pursuant to any such Requirement of Law or
Contractual Obligation except Liens created pursuant to the Loan Documents; and

                           (d) except as set forth in SCHEDULE 9(d), no consent
or authorization of, filing with or other act by or in respect of, any
Governmental Authority or any other Person (including, without limitation, any
stockholder or creditor of the Guarantor) is required in connection with the
execution, delivery, performance, validity or enforceability of this Guarantee
or any other Loan Document to which the Guarantor is a party.


                                       6
<PAGE>


                  The Guarantor agrees that the foregoing representations and
warranties shall be deemed to have been made by the Guarantor on the date of
each borrowing by the Borrower under the Credit Agreement on and as of such date
of borrowing as though made hereunder on and as of such date.

                  10. SEVERABILITY. (a) Any provision of this Guarantee which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                           (b) The parties hereto have agreed as provided in
SECTION 13 of this Guarantee and in the Credit Agreement, that New York law is
to govern, among other matters, the amount of interest that may lawfully be
charged, received or contracted for in connection with the Obligations. If,
notwithstanding such agreement, a court of competent jurisdiction applies the
law of any other jurisdiction to such interest, then the following shall apply:

                  It is expressly stipulated and agreed to be the intent of the
Guarantor and the Administrative Agent at all times to comply with applicable
state law governing the maximum rate or amount of interest payable with respect
to the Obligations (or applicable United States federal law to the extent that
it permits the Administrative Agent to contract for, charge, take, reserve or
receive a greater amount of interest than under state law, including, without
limitation, 12 U.S.C. ss. 85 (1994)). If the applicable law is ever judicially
interpreted so as to render usurious any amount called for under the Obligations
or under this Guarantee, or contracted for, charged, taken, reserved or received
with respect to the Obligations, then it is the Guarantor's and the
Administrative Agent's express intent that all excess amounts theretofore
collected by the Administrative Agent be credited on the principal balance of
the Obligations (or, if the Obligations have been or would thereby be paid in
full, refunded to the Guarantor), and the provisions of this Guarantee and all
other documents immediately be deemed reformed and the amounts thereafter
collectible hereunder and thereunder reduced, without the necessity of the
execution of any new documents, so as to comply with the applicable law, but so
as to permit the recovery of the fullest amount otherwise called for hereunder
or thereunder.

                  11. SECTION HEADINGS. The section headings used in this
Guarantee are for convenience of reference only and are not to affect the
construction hereof or be taken into consideration in the interpretation hereof.

                  12. NO WAIVER: CUMULATIVE REMEDIES. Neither the Administrative
Agent nor any Lender shall by any act (except by a written instrument pursuant
to SECTION 13), delay, indulgence, omission or otherwise be deemed to have
waived any right or remedy hereunder or to have acquiesced in any Default or
Event of Default or in any breach of any of the terms and conditions hereof. No
failure to exercise, nor any delay in exercising, on the part of the
Administrative Agent or any Lender, any right, power or privilege hereunder
shall operate as a waiver thereof. No single or partial exercise of any right,
power or privilege hereunder shall preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. A waiver by the
Administrative Agent or any Lender of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy which the


                                       7
<PAGE>


Administrative Agent or such Lender would otherwise have on any future occasion.
The rights and remedies herein provided are cumulative, may be exercised singly
or concurrently and are not exclusive of any rights or remedies provided by law.

                  13. INTEGRATION; WAIVERS AND AMENDMENTS; SUCCESSORS AND
ASSIGNS; GOVERNING LAW. This Guarantee represents the agreement of the Guarantor
with respect to the subject matter hereof and there are no promises or
representations by the Administrative Agent or any Lender relative to the
subject matter hereof not reflected herein. None of the terms or provisions of
this Guarantee may be waived, amended or supplemented or otherwise modified
except by a written instrument executed by the Guarantor and the Administrative
Agent; provided that any provision of this Guarantee may be waived by the
Administrative Agent and the Lenders in a letter or agreement executed by the
Administrative Agent or by telex or facsimile transmission from the
Administrative Agent. This Guarantee shall be binding upon the successors and
assigns of the Guarantor and shall inure to the benefit of the Administrative
Agent and their and their respective successors and assigns. THIS GUARANTEE AND
THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS GUARANTEE SHALL BE GOVERNED
BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS THEREOF OTHER THAN
SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK.

                  14. NOTICES. All notices, requests and demands to or upon the
Guarantor or the Administrative Agent or any Lender to be effective shall be in
writing or by telegraph or telex and, unless otherwise expressly provided
herein, shall be deemed to have been duly given or made when delivered by hand,
or, in the case of mail, three days after deposit in the postal system, first
class postage prepaid, or, in the case of telegraphic notice, when sent,
answerback received, addressed to a party at the address provided for such party
in the Credit Agreement or set forth under its signature below, as the case may
be.

                  15. SUBMISSION TO JURISDICTION: WAIVERS. (A) The Guarantor
hereby irrevocably and unconditionally:

                  (i) submits for itself and its property in any legal action or
proceeding relating to this Guarantee or any other Loan Document to which it is
party, or for recognition and enforcement of any judgment in respect thereof, to
the non-exclusive general jurisdiction of the courts of the State of New York,
the courts of the United States of America for the Southern District of New
York, and appellate courts from any thereof;

                  (ii) consents that any such action or proceeding may be
brought in such courts, and waives any objection that it may now or hereafter
have to the venue of any such action or proceeding in any such court or that
such action or proceeding was brought in any inconvenient court and agrees not
to plead or claim the same;

                  (iii) agrees that service of process in any such action or
proceeding may be effected by mailing a copy thereof by registered or certified
mail (or any substantially similar form of mail), postage prepaid, to the
Guarantor at its address set forth below or at such other address of which the
Administrative Agent shall have been notified pursuant thereto; and


                                       8
<PAGE>


                  (iv) agrees that nothing herein shall affect the right to
effect service of process in any other manner permitted by law or shall limit
the right to sue in any other jurisdiction; and

                  (v) waives, to the maximum extent not prohibited by law, any
right it may have to claim or recover in any legal action or proceeding referred
to in this Section any special, exemplary, punitive or consequential damages.

                  (B) THE GUARANTOR AND THE ADMINISTRATIVE AGENT HEREBY
IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR
PROCEEDING RELATING TO THIS GUARANTEE AND FOR ANY COUNTERCLAIM THEREIN.

<PAGE>

         that percentage as set forth in Schedule I of the issued and
         outstanding Capital Stock of the issuer in respect thereof;

                  (b) all the shares of Pledged Stock have been duly and validly
         issued and are fully paid and nonassessable;

                  (c) the Pledgor is the sole record and beneficial owner of,

         creditors' rights generally and by general equitable principles
         (whether enforcement is sought by proceedings in equity or at law); and

         where the Pledgor keeps its records concerning all contracts is located
         at One Eagle Square, Concord, New Hampshire 03301. [NOTE: AAVID TO
         CONFIRM ADDRESS.] The Pledgor shall not establish a new location for
         its chief executive office or change its name until (i) it has given to
         the Administrative Agent not less than 30 days' prior written notice of
         its intention to do so, clearly describing such new location or
         specifying such new name, as the case may be, and (ii) with respect to

         to maintain the security interest of the Administrative Agent in the
         Collateral intended to be granted hereby at all times fully perfected
         and in full force and effect.

                  5. COVENANTS. The Pledgor covenants and agrees with the
Administrative Agent and the Lenders that, from and after the date of this
Pledge Agreement until the Obligations are paid in full and the Commitments are
terminated:

                  (a) If the Pledgor, as a result of its ownership of the
         Pledged Stock, shall become entitled to receive or shall receive any
         Capital Stock certificates of any issuer of Pledged Stock (including,
         without limitation, any certificate representing a distribution of
         Capital Stock in connection with any reclassification, increase or
         reduction of capital or any certificate issued in connection with any
         reorganization), option or rights, whether in addition to, in
         substitution of, as a conversion of, or in exchange for any of the
         Pledged Stock, or otherwise in respect thereof, the Pledgor shall
         accept the same as the agent of the Administrative Agent and the
         Lenders, hold the same in trust for the benefit of the Administrative
         Agent and the Lenders and deliver the same forthwith to the
         Administrative Agent in the exact form received, duly endorsed by the
         Pledgor to the

                                       4

<PAGE>

         Administrative Agent, if required, together with an undated power
         covering such certificate duly executed in blank by the Pledgor to
         be held by the Administrative Agent, subject to the terms hereof, as
         additional collateral security for the Guarantee Obligations. Any
         sums paid upon or in respect of the Pledged Stock upon the
         liquidation or dissolution of any issuer of Pledged Stock and any
         distribution of capital in respect of the Pledged Stock or any cash
         pursuant to the recapitalization or reclassification of the capital
         of any issuer of Pledged Stock or pursuant to the reorganization
         thereof shall, within 15 days after receipt thereof by the
         Administrative Agent and in the sole discretion of the
         Administrative Agent, either be (i) applied in payment of the
         Obligations in such order as the Administrative Agent may elect or
         (ii) paid over to the Pledgor for its use in the operation of its
         business, and in case any distribution of capital shall be made on
         or in respect of the Pledged Stock or any property shall be
         distributed upon or with respect to the Pledged Stock pursuant to
         the recapitalization or reclassification of the capital of any
         issuer of Pledged Stock or pursuant to the reorganization thereof,
         the property so distributed shall be delivered to the Administrative
         Agent to be held by it hereunder as additional collateral security
         for the Guarantee Obligations. If any sums of money or property so
         paid or distributed in respect of the Pledged Stock shall be
         received by the Pledgor, the Pledgor shall, until such money or
         property is paid or delivered to the Administrative Agent, hold such
         money or property in trust for the benefit of the Lenders,
         segregated from other funds of the Pledgor, as additional collateral
         security for the Guarantee Obligations.

                  (b) Without the prior written consent of the Administrative
         Agent, the Pledgor will not (i) vote to enable, or take any other
         action to permit, any issuer of Pledged Stock to issue Capital Stock or
         other equity securities of any nature or to issue any other securities
         convertible into or granting the right to purchase or exchange for any
         Capital Stock or other equity securities of any nature of any issuer of
         Pledged Stock (other than any Capital Stock or other equity securities
         constituting Management Shares), (ii) sell, assign, transfer, exchange,
         or otherwise dispose of, or grant any option with respect to, the
         Collateral, or (iii) create, incur or permit to exist any other Lien or
         option in favor of, or any claim of any Person with respect to, any of
         the Collateral, or any interest therein, except for the Lien provided
         for by this Pledge Agreement. The Pledgor will defend and will
         indemnify and hold harmless the Administrative Agent and the Lenders
         against the claims and demands of all Persons whomsoever with respect
         to any claim arising from or in connection with the right, title and
         interest of the Administrative Agent and the Lenders in and to the
         Collateral.

                  (c) At any time and from time to time, upon the written
         request of the Administrative Agent, and at the sole expense of the
         Pledgor, the Pledgor will promptly and duly execute and deliver such
         further instruments and documents and take such further actions as the
         Administrative Agent may reasonably request for the purposes of
         obtaining or preserving the full benefits of this Pledge Agreement and
         of the rights and powers herein granted. If any amount payable under or
         in connection with any of the Collateral shall be or become evidenced
         by any promissory note, other instrument or chattel paper, such note,
         instrument or chattel paper shall be immediately delivered to the
         Administrative Agent, duly endorsed in a manner satisfactory to the
         Administrative Agent, to be held as Collateral pursuant to this Pledge
         Agreement.

                  (d) The Pledgor agrees to pay, and to save the Administrative
         Agent and the Lenders harmless from, any and all liabilities with
         respect to, or resulting from any delay in paying, any and all stamps,
         excise, sales or other taxes which may be payable or determined to be
         payable with respect to any of the Collateral or in connection with any
         of the transactions contemplated by this Pledge Agreement.

                  (e) The Pledgor agrees that, within 30 days of any
         corporation, limited liability company or similar entity becoming a
         Subsidiary (as defined in the Credit Agreement), in the case of shares
         of Capital Stock of such Subsidiary represented by one or more
         certificates, it shall (i) upon the request of the Administrative
         Agent, deliver to the Administrative Agent all such shares (or, in the
         case of any Foreign Subsidiary, 65% of such shares) owned by the
         Pledgor, together with, in each case, appropriate undated powers duly
         executed in blank and (ii) execute and deliver a new pledge agreement
         (or a supplement to this Pledge Agreement) covering such shares. Upon
         such delivery, such shares shall constitute a representation and
         warranty as of the date of such delivery that the representations and
         warranties contained in SECTION 4 above are true and correct on such
         date after giving effect to such delivery. The Pledgor shall also
         furnish to the Lenders such legal opinions confirming such
         representations and warranties as the Administrative Agent or any
         Lender may reasonably request.

                  6. CASH DISTRIBUTIONS; VOTING RIGHTS. Unless a Default or
Event of Default shall have occurred and be continuing, the Pledgor shall be
permitted to receive all cash dividends, distributions, interest and principal
paid on the Pledged Stock to the extent that such cash dividends, distributions,
interest and principal are permitted in the Credit Agreement and applicable
laws; PROVIDED that any such cash dividends, distributions, interest or
principal received by the Pledgor during the pendency of any Default (but prior
to the occurrence of an Event of Default) shall be returned promptly to the
issuer of such cash dividends, distributions, interest or principal, and any
such cash dividends, distributions, interest or principal received during the
pendency of any Default but not returned prior to such Default becoming an Event
of Default or during the pendency of any Event of Default shall be delivered
promptly to the Administrative Agent. Unless an Event of Default shall have
occurred and be continuing, the Pledgor shall be permitted to exercise all
voting and corporate rights with respect to the Pledged Stock; PROVIDED that no
vote shall be cast or corporate right exercised or other action taken which, in
the Administrative Agent's reasonable judgment, would impair the Collateral or
which would be inconsistent with or result in any violation of any provision of
the Credit Agreement, the Notes, the other Loan Documents or this Pledge
Agreement.

                  7. RIGHTS OF THE LENDERS AND THE ADMINISTRATIVE AGENT. (a) If

and principal paid in respect of the Pledged Stock, and to make application
thereof to the Obligations in such order as the Administrative Agent may
determine and (ii) all of the Pledged Stock shall be registered in the name of
the Administrative Agent or its nominee, and the Administrative Agent or its
nominee may thereafter exercise (A) all voting, corporate and other rights
pertaining to the Pledged Stock, and (B) any and all rights of conversion,
exchange, subscription and any other rights, privileges or options, pertaining
to any of the Pledged Stock as if it were the absolute owner thereof (including,
without limitation, the right to exchange at its discretion any and all the
Pledged

<PAGE>

Stock upon the merger, consolidation, reorganization, recapitalization or
other fundamental change in the corporate structure of any issuer of Pledged
Stock, or upon the exercise by the Pledgor or the Administrative Agent of any
right, privilege or option pertaining to any of the Pledged Stock, and in
connection therewith, the right to deposit and deliver any and all of the
Pledged Stock with any committee, depositary, transfer agent, registrar or
other designated agency upon such terms and conditions as it may determine),
all without liability to the Administrative Agent except to account for
property actually received by it, but the Administrative Agent shall have no
duty to the Pledgor to exercise any such right, privilege or option and shall
not be responsible for any failure to do so or delay in so doing.

                  (b) The rights of the Administrative Agent and the Lenders
hereunder shall not be conditioned or contingent upon the pursuit by the
Administrative Agent or any Lender of any right or remedy against the Pledgor,
any issuer of Pledged Stock, any guarantor or against any other Person which may
be or become liable in respect of all or any part of the Obligations or against
any collateral security therefor, guarantee therefor or right of offset with
respect thereto. Neither the Administrative Agent nor any Lender shall be liable
for any failure to demand, collect or realize upon all or any part of the
Collateral or for any delay in doing so, nor shall the Administrative Agent be
under any obligation to sell or otherwise dispose of any Collateral upon the
request of the Pledgor or any other Person or to take any other action
whatsoever with regard to the Collateral or any part thereof.

                  8. REMEDIES. If an Event of Default shall occur and be
continuing, the Administrative Agent, on behalf of the Lenders, may exercise, in
addition to all other rights and remedies granted in this Pledge Agreement and
in any other instrument or agreement securing, evidencing or relating to the
Obligations, all rights and remedies of a secured party under the Code. Without
limiting the generality of the foregoing, the Administrative Agent, without
demand of performance or other demand, presentment, protest, advertisement or
notice of any kind (except any notice required by law referred to below) to or
upon the Pledgor, any issuer of Pledged Stock, any guarantor or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby
waived to the maximum extent permitted by law), may in such circumstances
forthwith collect, receive, appropriate and realize upon the Collateral, or any
part thereof, and/or may forthwith sell, assign, give option or options to
purchase or otherwise dispose of and deliver the Collateral or any part thereof
(or contract to do any of the foregoing), in one or more parcels at public or
private sale or sales, in the over-the-counter market, at any exchange, broker's
board or office of the Administrative Agent or any Lender or elsewhere upon such
terms and conditions as it may deem advisable and at such prices as it may deem
best, for cash or on credit or for future delivery without assumption of any
credit risk. The Administrative Agent or any Lender shall have the right upon
any such public sale or sales, and, to the extent permitted by law, upon any
such private sale or sales, to purchase the whole or any part of the Collateral
so sold free of any right or equity of redemption in the Pledgor, which right or
equity is hereby waived or released to the maximum extent permitted by law. The
Administrative Agent shall apply any Proceeds from time to time held by it and
the net proceeds of any such collection, recovery, receipt, appropriation,
realization or sale, after deducting all reasonable costs and expenses of every
kind incurred in respect thereof or incidental to the care or safekeeping of any
of the Collateral or in any way relating to the Collateral or the rights of the
Administrative Agent and the Lenders hereunder, including, without limitation,
attorneys' fees and disbursements of counsel to the Administrative Agent, to the
payment in whole or in part of

                                       7

the Obligations, in such order as the Administrative Agent may elect, and
only after such application and after the payment by the Administrative Agent
of any other amount required by any provision of law, including, without
limitation, Section 9-504(1)(c) of the Code, need the Administrative Agent
account for the surplus, if any, to the Pledgor. To the extent permitted by
applicable law, the Pledgor waives all claims, damages and demands it may
acquire against the Administrative Agent or any Lender arising out of the
exercise by them of any rights hereunder. If any notice of a proposed sale or
other disposition of Collateral shall be required by law, such notice shall
be deemed reasonable and proper if given at least 10 days before such sale or
other disposition. The Pledgor shall remain liable for any deficiency if the
proceeds of any sale or other disposition of Collateral are insufficient to
pay the Obligations and the fees and disbursements of any attorneys employed
by the Administrative Agent or any Lender to collect such deficiency.

                  9. PRIVATE SALES. (a) The Pledgor recognizes that the
Administrative Agent may be unable to effect a public sale of any or all the
Pledged Stock, by reason of certain prohibitions contained in the Securities Act
of 1933 (the "SECURITIES ACT") and applicable state securities laws or
otherwise, and may be compelled to resort to one or more private sales thereof
to a restricted group of purchasers which will be obliged to agree, among other
things, to acquire such securities for their own account for investment and not
with a view to the distribution or resale thereof. The Pledgor acknowledges and
agrees that any such private sale may result in prices and other terms less
favorable than if such sale were a public sale and, notwithstanding such
circumstances, agrees that any such private sale shall be deemed to have been
made in a commercially reasonable manner. The Administrative Agent shall be
under no obligation to delay a sale of any of the Pledged Stock for the period
of time necessary to permit any issuer of Pledged Stock or the Pledgor to
register such securities for public sale under the Securities Act, or under
applicable state securities laws, even if such issuer or the Pledgor would agree
to do so.

                  (b) The Pledgor further agrees to use its best efforts to do
or cause to be done all such other acts as may be necessary to make such sale or
sales of all or any portion of the Pledged Stock pursuant to this SECTION 9
valid and binding and in compliance with any and all other applicable
Requirements of Law. The Pledgor further agrees that a breach of any of the
covenants contained in this SECTION 9 will cause irreparable injury to the
Administrative Agent and the Lenders, that the Administrative Agent and the
Lenders have no adequate remedy at law in respect of such breach and, as a
consequence, that each and every covenant contained in this SECTION 9 shall be
specifically enforceable against the Pledgor, and the Pledgor hereby waives and
agrees not to assert any defenses against an action for specific performance of
such covenants except for a defense that no Event of Default has occurred under
the Credit Agreement.

                  10. LIMITATION ON DUTIES REGARDING COLLATERAL. The
Administrative Agent's sole duty with respect to the custody, safekeeping and
physical preservation of the Collateral in its possession, under Section 9-207
of the Code or otherwise, shall be to deal with it in the same manner as the
Administrative Agent deals with similar securities and property for its own
account. None of the Administrative Agent, the Lenders or any of their
respective directors, officers, employees or agents shall be liable for failure
to demand, collect or realize upon any of the Collateral or for any delay in
doing so or shall be under any obligation to sell or otherwise dispose of any
Collateral upon the request of the Pledgor or otherwise.

                                       8

<PAGE>

                  11. POWERS COUPLED WITH AN INTEREST. All authorizations and
agencies herein contained with respect to the Collateral are irrevocable and
powers coupled with an interest.

                  12. SEVERABILITY. Any provision of this Pledge Agreement which
is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

                  13. SECTION HEADINGS. The section headings used in this Pledge
Agreement are for convenience of reference only and are not to affect the
construction hereof or be taken into consideration in the interpretation hereof.

                  14. NO WAIVER; CUMULATIVE REMEDIES. Neither the Administrative
Agent nor any Lender shall by any act (except by a written instrument pursuant
to SECTION 15) be deemed to have waived any right or remedy hereunder or to have
acquiesced in any Default or Event of Default or in any breach of any of the
terms and conditions hereof. No failure to exercise, nor any delay in
exercising, on the part of the Administrative Agent or any Lender, any right,
power or privilege hereunder shall operate as a waiver thereof. No single or
partial exercise of any right, power or privilege hereunder shall preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege. A waiver by the Administrative Agent or any Lender of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Administrative Agent or such Lender would otherwise
have on any future occasion. The rights and remedies herein provided are
cumulative, may be exercised singly or concurrently and are not exclusive of any
other rights or remedies provided by law.

                  15. WAIVERS AND AMENDMENTS; SUCCESSORS AND ASSIGNS; GOVERNING
LAW. None of the terms or provisions of this Pledge Agreement may be amended,
supplemented or otherwise modified except by a written instrument executed by
the Pledgor and the Administrative Agent; PROVIDED that any provision of this
Pledge Agreement may be waived by the Administrative Agent in a letter or
agreement executed by the Administrative Agent or by telex or facsimile
transmission from the Administrative Agent. This Pledge Agreement shall inure to
the benefit of the Administrative Agent and the Lenders and their respective
successors and assigns. THIS PLEDGE AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES UNDER THIS PLEDGE AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD
TO THE PRINCIPLES OF CONFLICT OF LAWS THEREOF OTHER THAN SECTION 5-1401 OF THE
GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK.

                  16. NOTICES. Notices may be given by mail, by telex or by
facsimile transmission, addressed or transmitted to the Person to which it is
being given at such Person's address or transmission number set forth in the
Credit Agreement and shall be effective (a) in the case of mail, three days
after deposit in the postal system, first class postage pre-paid, and (b) in the
case of telex or facsimile notices, when sent if receipt is confirmed by
telephone. The Pledgor and any issuer of Pledged Stock may change their
respective addresses and transmission numbers by written notice to the
Administrative Agent.

<PAGE>

                  17. IRREVOCABLE AUTHORIZATION AND INSTRUCTION TO ISSUERS. The
Pledgor hereby authorizes and instructs each issuer of Pledged Stock to comply
with any instruction received by it from the Administrative Agent in writing
that (a) states that an Event of Default has occurred and (b) is otherwise in
accordance with the terms of this Pledge Agreement, without any other or further
instructions from the Pledgor, and the Pledgor agrees that such issuer of
Pledged Stock shall be fully protected in so complying.

                  18. AUTHORITY OF AGENT. The Pledgor acknowledges that the
rights and responsibilities of the Administrative Agent under this Pledge
Agreement with respect to any action taken by the Administrative Agent or the
exercise or non-exercise by the Administrative Agent of any option, voting
right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Pledge Agreement shall, as between the
Administrative Agent and the Lenders, be governed by the Credit Agreement and by
such other agreements with respect thereto as may exist from time to time among
them, but, as between the Administrative Agent and the Pledgor, the
Administrative Agent shall be conclusively presumed to be acting as agent for
the Lenders with full and valid authority so to act or refrain from acting, and
neither the Pledgor nor any issuer of Pledged Stock shall be under any
obligation, or entitlement, to make any inquiry respecting such authority.

                  19. TERMINATION; RELEASE. Upon the repayment of all the
Obligations in full and the termination of the Commitments, this Pledge
Agreement shall terminate, and the Administrative Agent, at the request of and
sole expense of the Pledgor, will execute and deliver to the Pledgor the proper
instruments (including Uniform Commercial Code termination statements on form
UCC-2 or UCC-3, as applicable) acknowledging the termination of this Pledge
Agreement, and will duly assign, transfer and deliver to the Pledgor (without
recourse and without any representation or warranty of any kind) such of the
Collateral as may be in the possession of the Administrative Agent and has not
theretofore been disposed of or otherwise applied or released.

                  20. COUNTERPARTS. This Pledge Agreement may be executed in
counterparts, and all of such counterparts taken together shall be deemed to
constitute one and the same instrument.

2 above or under this PARAGRAPH 4, and (ii) by filing with the Patent and
Trademark Office, in addition to and not in substitution for this Agreement, a
duplicate original of this Agreement containing on SCHEDULE A or B thereto, as
the case may be, such future patents, trademarks, registered trademarks,
trademark applications, service marks, patent applications, registered service
marks and service mark applications, and patent license agreements, trademark
license agreements and service mark license agreements.

                  5. ROYALTIES. The Grantor hereby agrees that the use by the
Administrative Agent of the Patents, Trademarks and Licenses as authorized
hereunder in connection with the Administrative Agent's exercise of its rights
and remedies under PARAGRAPH 13 or pursuant to the Security Agreements shall be
coextensive with the Grantor's rights thereunder and with respect thereto and
without any liability for royalties or other related charges from the
Administrative Agent and the Lenders to the Grantor.

                  6. FURTHER ASSIGNMENTS AND SECURITY INTERESTS. The Grantor
agrees not to sell or assign its respective interests in, or grant any license
under, the Patents, the Trademarks or the Licenses without the prior and express
written consent of the Administrative Agent.

                  7. Nature and Continuation of the Administrative Agent's
Security Interest; Termination of the Administrative Agent's Security Interest;
Release of Collateral. This Agreement is made for collateral security purposes
only. This Agreement shall create a continuing security interest in the Patents,
Trademarks and Licenses and shall terminate only when the Obligations have been
paid in full in cash and the Credit Agreement and the Security Agreements have
been terminated. Upon such termination and at the written request of the Grantor
or its successors or assigns, and at the cost and expense of the Grantor or its
successors or assigns, the Administrative Agent shall execute in a timely manner
such instruments, documents or agreements as are necessary or desirable to
terminate the Administrative Agent's security interest in the Patents, the
Trademarks and the Licenses, subject to any disposition thereof which may have
been made by the Administrative Agent pursuant to this Agreement or the Security
Agreements.

                  8. DUTIES OF THE GRANTOR. Subject to the second sentence of
this Section 8, the Grantor shall have the duty (i) to prosecute diligently any
patent application, trademark application or service mark application that is
part of the Trademarks pending as of the date hereof or hereafter until the
termination of this Agreement and (ii) to make any application for and
diligently prosecute the registration of (x) any trademark or service mark that
the Grantor has not created as of the date hereof which the Administrative
Agent, after consultation with the Grantor, reasonably determines may have
significant value and (y) any unpatented but patentable invention. The Grantor
further agrees (i) not to abandon any Trademark or License without the prior
written consent of the Administrative Agent if such abandonment would have a
Material Adverse Effect, and (ii) to use its reasonable best efforts to obtain
and maintain in full force and effect the Patents, the Trademarks and the
Licenses that are or shall be necessary or economically desirable in the
operation of the Grantor's business. Any expenses incurred in connection with
the foregoing shall be borne by the Grantor. Neither the Administrative Agent
nor any of the Lenders shall have any duty with respect to the Patents,
Trademarks and Licenses. Without limiting the generality of the foregoing,
neither the Administrative Agent nor any of the Lenders shall be under any
obligation to take any steps necessary to preserve rights in the Patents, the
Trademarks or Licenses against any other parties, but the Administrative Agent
may do so at its option from and after the occurrence of an Event of Default,
and all expenses incurred in connection therewith shall be for the sole account
of the Grantor and shall be added to the Obligations secured hereby.

                  9. THE ADMINISTRATIVE AGENT'S RIGHT TO SUE. Upon the
occurrence and during the continuance of an Event of Default, the Administrative
Agent shall have the right, but shall not be obligated, to bring suit in its own
name to enforce the Patents, the Trademarks and the Licenses and, if the
Administrative Agent shall commence any such suit, the Grantor shall, at the
request of the Administrative Agent, do any and all lawful acts and execute any
and all proper documents required by the Administrative Agent in aid of such
enforcement. The Grantor shall, upon demand, promptly reimburse the
Administrative Agent for all actual costs and expenses incurred by the
Administrative Agent in the exercise of its rights under this


                                      5
<PAGE>



PARAGRAPH 9 (including, without limitation, reasonable fees and expenses of
counsel for the Administrative Agent).

                  10. WAIVERS. The Administrative Agent's failure, at any time
or times hereafter, to require strict performance by the Grantor of any
provision of this Agreement shall not waive, affect or diminish any right of the
Administrative Agent thereafter to demand strict compliance and performance
therewith nor shall any course of dealing between the Grantor and the
Administrative Agent have such effect. No single or partial exercise of any
right hereunder shall preclude any other or further exercise thereof or the
exercise of any other right. None of the undertakings, agreements, warranties,
covenants and representations of the Grantor contained in this Agreement shall
be deemed to have been suspended or waived by the Administrative Agent unless
such suspension or waiver is in writing signed by an officer of the
Administrative Agent and directed to the Grantor specifying such suspension or
waiver.

                  11. SEVERABILITY. If any provision of this Agreement is held
to be prohibited or unenforceable in any jurisdiction the substantive laws of
which are held to be applicable hereto, such prohibition or unenforceability
shall not affect the validity or enforceability of the remaining provisions
hereof and shall not invalidate or render unenforceable such provision in any
other jurisdiction.

                  12. MODIFICATION. This Agreement cannot be altered, amended or
modified in any way, except as specifically provided in PARAGRAPH 4 hereof or by
a writing signed by the parties hereto.

                  13. CUMULATIVE REMEDIES; POWER OF ATTORNEY. The Grantor
agrees, upon the request of the Administrative Agent and promptly following such
request, to take any action and execute any instrument which the Administrative
Agent may deem necessary or advisable to accomplish the purposes of this
Agreement. The Grantor hereby irrevocably designates, constitutes and appoints
the Administrative Agent (and all Persons designated by the Administrative Agent
in its sole and absolute discretion) as the Grantor's true and lawful
attorney-in-fact, and authorizes the Administrative Agent and any of the
Administrative Agent's designees, in the Grantor's or the Administrative Agent's
name, from and after the occurrence and during the continuance of an Event of
Default, to take any action and execute any instrument which the Administrative
Agent may deem necessary or advisable to accomplish the purposes of this
Agreement, including, without limitation, (i) to endorse the Grantor's name on
all applications, documents, papers and instruments necessary or desirable for
the Administrative Agent in the use, prosecution or protection of the Patents,
the Trademarks or the Licenses, (ii) to assign, pledge, convey or otherwise
transfer title in or dispose of the Trademarks or the Licenses to anyone on
commercially reasonable terms, (iii) to grant or issue any exclusive or
nonexclusive license under the Patents, the Trademarks or the Licenses, to
anyone on commercially reasonable terms, and (iv) to take any other actions with
respect to the Patents or the Trademarks or, to the extent permitted, the
Licenses as the Administrative Agent deems in its own or the Lenders' best
interest. The Grantor hereby ratifies all that such attorney shall lawfully do
or, to the extent permitted, cause to be done by virtue hereof. This power of
attorney is coupled with an interest and shall be irrevocable until all the
Obligations shall have been paid in full in cash and the Credit Agreement shall
have been terminated. The Grantor acknowledges and agrees that this Agreement is
not intended to limit or restrict in any way the rights and remedies of the


                                     6
<PAGE>



Administrative Agent or the other Lenders under the Agreement, but rather is
intended to facilitate the exercise of such rights and remedies.

                  The Administrative Agent shall have, in addition to all other
rights and remedies given it by the terms of this Agreement, all rights and
remedies allowed by law and the rights and remedies of a secured party under the
Uniform Commercial Code as enacted in any jurisdiction in which the Trademarks
or the Licenses may be located or deemed located. If an Event of Default has
occurred and is continuing and the Administrative Agent has elected to exercise
any of its remedies under Section 9-504 or Section 9-505 of the Uniform
Commercial Code with respect to the Patents, Trademarks and Licenses, the
Grantor agrees to assign, convey and otherwise transfer all of its title in and
to the Patents, the Trademarks and the Licenses to the Administrative Agent or
any transferee of the Administrative Agent and to execute and deliver to the
Administrative Agent or any such transferee all such agreements, documents and
instruments as may be necessary, in the Administrative Agent's sole discretion,
to effect such assignment, conveyance and transfer; PROVIDED that in the case of
any Patents, Trademarks and Licenses licensed to the Borrower by third parties,
such transfer shall be solely to the extent any of the foregoing are
transferable pursuant to operative agreements between the Borrower and such
third party. All the Administrative Agent's rights and remedies with respect to
the Patents, the Trademarks and the Licenses, whether established hereby, by the
Security Agreements, by any other agreements or by law, shall be cumulative and
may be exercised separately or concurrently. Notwithstanding anything set forth
herein to the contrary, it is hereby expressly agreed that if an Event of
Default has occurred and is continuing, the Administrative Agent may exercise
any of the rights and remedies provided in this Agreement, the Security
Agreements and any of the other Loan Documents. The Grantor agrees that any
notification of intended disposition of any of the Patents, Trademarks and
Licenses required by law shall be deemed reasonably and properly given if given
at least ten (10) days before such disposition; PROVIDED, that the
Administrative Agent may give any shorter notice that is commercially reasonable
under the circumstances.

                  14. SUCCESSORS AND ASSIGNS. This Agreement shall be binding
upon the Grantor and its successors and assigns, and shall inure to the benefit
of each of the Lenders and its nominees, successors and assigns. The Grantor's
successors and assigns shall include, without limitation, a receiver, trustee or
debtor-in-possession of or for the Grantor; PROVIDED, that the Grantor shall not
voluntarily assign or transfer its rights or obligations hereunder without the
Administrative Agent's prior written consent.

                  15. GOVERNING LAW. This Agreement shall be governed by, and be
construed and interpreted in accordance with, the law (without regards to
conflict of law provisions (other than Section 5-1401 of the General Obligations
Law)) of the State of New York, except for perfection and enforcement of
security interests and liens in other jurisdictions to the extent the law of
another jurisdiction is, pursuant to the laws of such jurisdiction, mandatorily
applicable.

                  16. NOTICES. All notices or other communications hereunder
shall be given in the manner and to the addresses set forth in Section 9.2 of
the Credit Agreement.

                  17. AUTHORITY OF ADMINISTRATIVE AGENT. The Grantor
acknowledges that the rights and responsibilities of the Administrative Agent
under this Agreement with respect to any


                                      7
<PAGE>



action taken by the Administrative Agent or the exercise or non-exercise by
the Administrative Agent of any option, right, request, judgment or other
right or remedy provided for herein or resulting or arising out of this
Agreement shall, as between the Administrative Agent and the Lenders, be
governed by the Credit Agreement and by such other agreements with respect
thereto as may exist from time to time among them, but, as between the
Administrative Agent and the Grantor, the Administrative Agent shall be
conclusively presumed to be acting as agent for the Lenders with full and
valid authority so to act or refrain from acting, and the Grantor shall not
be under any obligation, or entitlement, to make any inquiry respecting such
authority.

                  18. TERMINATION; RELEASE. Upon the repayment of all the
Obligations in full and the termination of the Commitments, this Agreement shall
terminate, and the Administrative Agent, at the request and expense of the
Grantor, will promptly execute and deliver to the Grantor the proper instruments
acknowledging the termination of this Agreement, and will duly assign, transfer
and deliver to Grantor (without recourse and without any representation or
warranty of any kind) such of the Collateral as may be in the possession of the
Administrative Agent and has not theretofore been disposed of or otherwise
applied or released.

                  19. REINSTATEMENT. This Agreement shall continue to be
effective or be reinstated, as the case may be, if at any time any amount
received by the Lenders in respect of the Obligations is rescinded or must
otherwise be restored or returned by such Lender upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Grantor or upon
the appointment of any intervenor or conservator of, or trustee or similar
official for, the Grantor or any substantial part of its assets, or upon the
entry of an order by a bankruptcy court avoiding payment of such amount, or
otherwise, all as though such payments had not been made.

                  20. SECTION TITLES. The section titles herein are for
convenience of reference only, and shall not affect in any way the
interpretation of any of the provisions hereof.

                  21. EXECUTION IN COUNTERPARTS. This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.

                  22. SUBMISSION TO JURISDICTION AND SERVICE OF PROCESS. The
Grantor hereby irrevocably and unconditionally agrees that the terms of Section
9.13 of the Credit Agreement with respect to submission to jurisdiction and
service of process shall apply equally to this Agreement.

                  23. WAIVER OF BOND. The Grantor waives the posting of any bond
otherwise required of the Administrative Agent in connection with any judicial
process or proceeding to realize on any of the Patents, Trademarks or Licenses
or any other security for the Obligations, to enforce any judgment or other
court order entered in favor of the Administrative Agent, or to enforce by
specific performance, temporary restraining order, or preliminary or permanent

                                       8
<PAGE>



injunction, this Agreement or any other agreement or document between the
Administrative Agent and the Grantor.

                  24. WAIVER OF JURY TRIAL. EACH OF THE GRANTOR AND THE
ADMINISTRATIVE AGENT WAIVES ANY RIGHT TO TRIAL BY JURY IN ANY DISPUTE, WHETHER
SOUNDING IN CONTRACT, TORT, OR OTHERWISE, BETWEEN THE ADMINISTRATIVE AGENT AND
THE GRANTOR ARISING OUT OF OR RELATED TO THE TRANSACTIONS CONTEMPLATED BY THIS
AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT, OR AGREEMENT EXECUTED OR DELIVERED
IN CONNECTION HEREWITH. EITHER THE GRANTOR OR THE ADMINISTRATIVE AGENT MAY FILE
AN ORIGINAL COUNTERPART OR A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN
EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO
TRIAL BY JURY.

ADMINISTRATIVE AGENT'S AND LENDERS' OBLIGATIONS.

                  (a) GRANTOR REMAINS LIABLE UNDER ACCOUNTS AND CONTRACTS.
Anything herein to the contrary notwithstanding, the Grantor shall remain liable
under each of the Accounts and Contracts to observe and perform all the
conditions and obligations to be observed and performed by it thereunder, all in
accordance with the terms of any agreement giving rise to each such Account and
in accordance with and pursuant to the terms and provisions of each such
Contract. Neither the Administrative Agent nor any Lender shall have any
obligation or liability under any Account (or any agreement giving rise thereto)
or under any Contract by reason of or arising out of this Security Agreement or
the receipt by the Administrative Agent or any such Lender of any payment
relating to such Account or Contract pursuant hereto, nor shall the
Administrative Agent or any Lender be obligated in any manner to perform any of
the obligations of the Grantor under or pursuant to any Account (or any
agreement giving rise thereto) or under or pursuant to any Contract, to make any
payment, to make any inquiry as to the nature or the sufficiency of any payment
received by it or as to the sufficiency of any performance by any party under
any Account (or any agreement giving rise thereto) or under any Contract, 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 it or to
which it may be entitled at any time or times.

                  (b) NOTICE TO ACCOUNT DEBTORS AND CONTRACTING PARTIES. At any
time after the occurrence and during the continuance of an Event of Default, the
Administrative Agent shall have the right at any time, upon written notice to
the Grantor of its intention to do so, to notify account debtors or obligors on
the Accounts and parties to the Contracts that the Accounts and the Contracts
have been assigned to the Administrative Agent for the ratable benefit of the
Lenders and that payments due or to become due to the Grantor in respect thereof
shall be made directly to the Administrative Agent and, upon such notification,
and at the expense of the Grantor, to enforce collection of any such Accounts.
The Administrative Agent may, at any time, in its own name or in the name of the
Lenders or the Grantor communicate with account debtors on the Accounts and
parties to the Contracts to verify with them to its satisfaction the existence,
amount and terms of any Accounts or Contracts. Unless an Event of Default shall
have occurred and be continuing, the Administrative Agent shall not exercise its
right under this clause (b) more than once in any 12-month period.


                                       4

                  (c) COLLECTIONS ON ACCOUNTS. The Administrative Agent hereby
authorizes the Grantor to collect the Accounts; PROVIDED that the Administrative
Agent may curtail or terminate said authority at any time after the occurrence
of an Event of Default. If required by the Administrative Agent at any time
after the occurrence and during the continuance of an Event of Default, any
payments of Accounts, when collected by the Grantor, shall be forthwith (and, in
any event, within two Business Days) deposited by the Grantor in the exact form
received, duly endorsed by the Grantor to the Administrative Agent if required,
in a special collateral account maintained by the Administrative Agent, subject
to withdrawal by the Administrative Agent for the account of the Lenders only,
as hereinafter provided, and, until so turned over, shall be held by the Grantor
in trust for the Administrative Agent and the Lenders, segregated from other
funds of the Grantor. Each deposit of any such Proceeds shall be accompanied by
a report identifying in reasonable detail the nature and source of the payments
included in the deposit. All Proceeds constituting collections of Accounts while
held by the Administrative Agent (or by the Grantor in trust for the
Administrative Agent and the Lenders) shall continue to be collateral security
for all the Obligations and shall not constitute payment thereof until applied
as hereinafter provided. At such intervals as may be agreed upon by the Grantor
and the Administrative Agent, or, if an Event of Default shall have occurred and
be continuing, at any time at the Administrative Agent's election, the
Administrative Agent shall apply all or any part of the funds on deposit in said
special collateral account on account of the Obligations in such order as the
Administrative Agent may elect, and any part of such funds which the
Administrative Agent elects not so to apply and deems not required as collateral
security for the obligations shall be paid over from time to time by the
Administrative Agent to the Grantor or to whomsoever may lawfully be entitled to
receive the same (it being understood that (i) prior to any Event of Default
that is continuing, the Grantor shall be permitted to use such funds in the
operation of its business in a manner consistent with the terms of the Credit
Agreement and (ii) within fifteen days after the occurrence of any Event of
Default, the Administrative Agent shall, in its sole discretion, either apply
such funds in payment of the Obligations in such order as the Administrative
Agent may elect or permit the Grantor to use such funds in the operation of its
business). Upon the occurrence of an Event of Default that is continuing, at the
Administrative Agent's request, the Grantor shall deliver to the Administrative
Agent all original and other documents evidencing, and relating to, the
agreements and transactions which gave rise to the Accounts, including, without
limitation, all original orders, invoices and shipping receipts.

                  (d) ANALYSIS OF ACCOUNTS. The Administrative Agent shall have
the right to make test verifications of the Accounts in any manner and through
any medium that it reasonably considers advisable, and the Grantor shall furnish
all such assistance and information as the Administrative Agent may require in
connection therewith; PROVIDED that the Administrative Agent shall use its
reasonable efforts to minimize any disruption of the Grantor's business
resulting from such verifications. At any time and from time to time if the
Administrative Agent concludes in its reasonable judgment, based upon its
evaluation of the general creditworthiness of the Grantor, that such examination
is required, and so requests, the Grantor at its own expense shall cause
independent public accountants or other parties that are not Affiliates of the
Grantor and are reasonably satisfactory to the Administrative Agent to furnish
to the Administrative Agent reports showing reconciliations, aging and test
verifications of, and trial balances for, the Accounts. Unless an Event of
Default shall have occurred and be


                                       5

continuing, the Administrative Agent shall not exercise its right under this
clause (d) more than once in any 12-month period.

                  4. REPRESENTATIONS AND WARRANTIES. The Grantor hereby
represents and warrants that:

                  (a) TITLE; NO OTHER LIENS. Except as permitted under Section
6.3 of the Credit Agreement, the Grantor owns or has a valid leasehold interest
in each item of the Collateral free and clear of any and all Liens or claims of
others. Except as permitted under Section 6.3(e) of the Credit Agreement, no
security agreement, financing statement or other public notice with respect to
all or any part of the Collateral is on file or of record in any public office,
except (i) such as may have been filed in favor of the Administrative Agent, for
the ratable benefit of the Lenders, pursuant to this Security Agreement and (ii)
financing statements filed by lessors solely for information purposes in respect
of "true" leases.

                  (b) PERFECTED FIRST PRIORITY LIENS. Except as permitted under
Section 6.3(e) of the Credit Agreement, the Liens granted pursuant to this
Security Agreement will, upon the filing of appropriate financing statements,
constitute valid and perfected first priority Liens on the Collateral in favor
of the Administrative Agent, for the ratable benefit of the Lenders, and against
any owner or purchaser of the real property where any of the Equipment is
located and any present or future creditor obtaining a Lien on such real
property, except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditor's rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

                  (c) ACCOUNTS. The amount represented by the Grantor to the
Lenders from time to time as owing by each account debtor or by all account
debtors in respect of the Accounts will at such time be the correct amount
actually owing by such account debtor or debtors thereunder. No amount payable
to the Grantor under or in connection with any Account is evidenced by any
Instrument or Chattel Paper which has not been delivered to the Administrative
Agent. The place where the Grantor keeps its records concerning the Accounts is
143 North Main Street, Suite 206, Concord, NH 03301.

                  (d) CONTRACTS. Except as set forth in Schedule 3.4 to the
Credit Agreement, no consent of any party (other than the Grantor) to any
Contract is required in connection with the execution, delivery and performance
by the Grantor of this Security Agreement. Each Contract is in full force and
effect and constitutes a valid and legally enforceable obligation of the parties
thereto, except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditor's rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law). No consent or
authorization of, filing with or other act by or in respect of any Governmental
Authority is required in connection with the execution, delivery or performance
by the Grantor of, or the validity or enforceability of, any of the Contracts by
any party thereto other than those which have been duly obtained, made or
performed, are in full force and effect and do not subject the scope of any such
Contract to any material adverse limitation, either specific or general in
nature. Neither the Grantor nor (to the best of the Grantor's knowledge) any
other party to any Contract is in default in any material respect in the
performance or observance of


                                       6

<PAGE>


any of the terms thereof. The Grantor has fully performed in all material
respects all its obligations under each Contract. The right, title and
interest of the Grantor in, to and under each Contract are not subject to any
defense, offset, counterclaim or claim which would materially adversely
affect the value of such Contract as Collateral, nor have any of the
foregoing been asserted or alleged against the Grantor as to any Contract.
The Grantor has delivered to the Administrative Agent a complete and correct
copy of each material Contract, including all amendments, supplements and
other modifications thereto and will deliver any other Contract which the
Administrative Agent may request. No amount payable to the Grantor under or
in connection with any Contract is evidenced by any Instrument or Chattel
Paper which has not been delivered to the Administrative Agent.

                  (e) INVENTORY AND EQUIPMENT. The Inventory and the Equipment
are kept at the locations listed on Schedule I hereto.

                  (f) CHIEF EXECUTIVE OFFICE. The Grantor's chief executive
office and chief place of business is located at 143 North Main Street, Suite
206, Concord, NH 03301.

                  (g) FARM PRODUCTS. None of the Collateral constitutes, or is
the Proceeds of, Farm Products.

                  (h) GOVERNMENTAL OBLIGORS. None of the obligors on any
Accounts, and none of the parties to any Contracts, is a Governmental Authority.

                  (i)      INVESTMENT PROPERTY.  The Investment Property
consists of the items set forth on Annex A.

                  5. COVENANTS. The Grantor covenants and agrees with the
Administrative Agent and the Lenders that, from and after the date of this
Security Agreement until the Obligations are paid in full and the Commitments
are terminated:

                  (a) FURTHER DOCUMENTATION; PLEDGE OF INSTRUMENTS AND CHATTEL
PAPER. At any time and from time to time, upon the written request of the
Administrative Agent, and at the sole expense of the Grantor, the Grantor will
promptly and duly execute and deliver such further instruments and documents and
take such further action as the Administrative Agent may reasonably request for
the purpose of obtaining or preserving the full benefits of this Security
Agreement and of the rights and powers herein granted, including, without
limitation, the filing of any financing or continuation statements under the
Uniform Commercial Code in effect in any jurisdiction with respect to the Liens
created hereby. The Grantor also hereby authorizes the Administrative Agent to
file any such financing or continuation statement without the signature of the
Grantor to the extent permitted by applicable law. A carbon, photographic or
other reproduction of this Security Agreement shall be sufficient as a financing
statement for filing in any jurisdiction. If any amount payable under or in
connection with any of the Collateral shall be or become evidenced by any
Instrument or Chattel Paper, such Instrument or Chattel Paper shall be
immediately delivered to the Administrative Agent, duly endorsed in a manner
satisfactory to the Administrative Agent, to be held as Collateral pursuant to
this Security Agreement.


                                       7

                  (b) INDEMNIFICATION. The Grantor agrees to pay, and to save
the Administrative Agent and the Lenders harmless from, any and all liabilities,
costs and expenses (including, without limitation, legal fees and expenses) (i)
with respect to, or resulting from, any delay in paying any and all excise,
sales or other taxes which may be payable or determined to be payable with
respect to any of the Collateral, (ii) with respect to, or resulting from, any
delay in complying with any Requirement of Law applicable to any of the
Collateral or (iii) in connection with any of the transactions contemplated by
this Security Agreement, except resulting from the Administrative Agent's or any
Lender's gross negligence or willful misconduct. In any suit, proceeding or
action brought by the Administrative Agent or any Lender under any Account or
Contract for any sum owing thereunder, or to enforce any provisions of any
Account or Contract, the Grantor will save, indemnify and keep the
Administrative Agent and such Lender harmless from and against all expense, loss
or damage suffered by reason of any defense, setoff, counterclaim, recoupment or
reduction or liability whatsoever of the account debtor or obligor thereunder,
arising out of a breach by the Grantor of any obligation thereunder or arising
out of any other agreement, indebtedness or liability at any time owing to or in
favor of such account debtor or obligor or its successors from the Grantor,
except resulting from the Administrative Agent's or any Lender's gross
negligence or willful misconduct.

                  (c) MAINTENANCE OF RECORDS. The Grantor will keep and maintain
at its own cost and expense satisfactory and complete records of the Collateral,
including, without limitation, a record of all payments received and all credits
granted with respect to the Accounts. The Grantor will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby in such manner as the Administrative Agent may
request. For the Administrative Agent's and the Lenders' further security, the
Administrative Agent, for the ratable benefit of the Lenders, shall have a
security interest in all the Grantor's books and records pertaining to the
Collateral, and the Grantor shall, during the continuance of a Default under
Section 7.1(a) of the Credit Agreement or Section 7.1(c) of the Credit Agreement
as it relates to Section 6.1 of the Credit Agreement, turn over copies of such
books and records and during the continuation of an Event of Default turn over
any such books and records, in each case, to the Administrative Agent or to its
representatives at the request of the Administrative Agent.

                  (d) RIGHT OF INSPECTION. The Administrative Agent and the
Lenders shall at all times have full and free access during normal business
hours and, so long as no Event of Default shall have occurred and be continuing,
upon reasonable prior notice, to all books, correspondence and records of the
Grantor, and the Administrative Agent and the Lenders and their respective
representatives may examine the same, take extracts therefrom and make
photocopies thereof, and the Grantor agrees to render to the Administrative
Agent and the Lenders, at the Grantor's cost and expense, such clerical and
other assistance as may be reasonably requested with regard thereto. The
Administrative Agent and the Lenders and their respective representatives shall
at all times and, so long as no Event of Default shall have occurred and be
continuing, upon reasonable prior notice, also have the right to enter into and
upon any premises where any of the Inventory or Equipment is located for the
purpose of inspecting the same, observing its use or otherwise protecting its
interests therein.

                  (e) COMPLIANCE WITH LAWS. The Grantor will comply in all
material respects with all Requirements of Law applicable to the Collateral or
any part thereof or to the operation


                                       8

<PAGE>


of the Grantor's business; PROVIDED that the Grantor may contest any
Requirement of Law in any reasonable manner which shall not, in the sole
opinion of the Administrative Agent, adversely affect the Administrative
Agent's or the Lenders' rights or the priority of their Liens on the
Collateral.

                  (f) COMPLIANCE WITH TERMS OF CONTRACTS. The Grantor will
perform and comply in all material respects with all its obligations under the
Contracts and all its other Contractual Obligations relating to the Collateral.

                  (g) PAYMENT OF OBLIGATIONS. The Grantor will pay promptly when
due all taxes, assessments and governmental charges or levies imposed upon the
Collateral or in respect of its income or profits therefrom, as well as all
claims of any kind (including, without limitation, claims for labor, materials
and supplies) against or with respect to the Collateral, except that no such
charge need be paid if (i) the validity thereof is being contested in good faith
by appropriate proceedings, (ii) such proceedings do not involve any material
danger of the sale, forfeiture or loss of any of the Collateral or any interest
therein and (iii) such charge is adequately reserved against on the Grantor's
books in accordance with GAAP.

                  (h) LIMITATION ON LIENS ON COLLATERAL. The Grantor will not
create, incur or permit to exist, will defend the Collateral against, and will
take such other action as is necessary to remove, any Lien or claim on or to the
Collateral, other than the Liens created hereby and other than as permitted
pursuant to Section 6.3 of the Credit Agreement, and will defend the right,
title and interest of the Administrative Agent and the Lenders in and to any of
the Collateral against the claims and demands of all Persons whomsoever.

                  (i) LIMITATIONS ON DISPOSITIONS OF COLLATERAL. The Grantor
will not sell, transfer, lease or otherwise dispose of any of the Collateral, or
attempt, offer or contract to do so except as permitted pursuant to Section 6.6
of the Credit Agreement.

                  (j) LIMITATIONS ON MODIFICATIONS, WAIVERS, EXTENSIONS OF
CONTRACTS AND AGREEMENTS GIVING RISE TO ACCOUNTS. Subject to subsection (k)
below, the Grantor will not (i) amend, modify, terminate or waive any provision
of any Material Contract or any agreement giving rise to an Account in any
manner which could reasonably be expected to materially adversely affect the
value of such Contract or Account as Collateral, (ii) fail to exercise promptly
and diligently each and every material right which it may have under each
Contract and each agreement giving rise to an Account (other than any right of
termination) or (iii) fail to deliver to the Administrative Agent a copy of each
material demand, notice or document received by it relating in any way to any
Contract or any agreement giving rise to an Account. As used in this clause (j),
a "Material Contract" shall mean (x) any purchase order or license agreement by
Fluent Holdings, Inc., a Delaware corporation (successor to Fluent, Inc., a New
Hampshire corporation) with a value of more than $750,000 in any 12-month period
or (y) any other contract with a stated duration (including any extension
periods contained therein) of more than 12 months and with a value of more than
$750,000.

                  (k) LIMITATIONS ON DISCOUNTS, COMPROMISES, EXTENSIONS OF
ACCOUNTS. Other than in the ordinary course of business, the Grantor will not
grant any extension of the time of payment of any of the Accounts, compromise,
compound or settle the same for less than the full


                                       9

<PAGE>


amount thereof, release, wholly or partially, any Person liable for the
payment thereof, or allow any credit or discount whatsoever thereon.

                  (l) MAINTENANCE OF EQUIPMENT. The Grantor will maintain each
item of Equipment not subject to Section 6.6(a) of the Credit Agreement in good
operating condition, ordinary wear and tear and immaterial impairments of value
and damage by the elements excepted, and will provide all maintenance, service
and repairs necessary for such purpose.

                  (m) MAINTENANCE OF INSURANCE. The Grantor will maintain, with
financially sound and reputable companies, insurance policies as required under
the Credit Agreement. All such policies shall (i) contain a breach of warranty
clause in favor of the Administrative Agent and the Lenders, (ii) provide that
no cancellation, material reduction in amount or material change in coverage
thereof shall be effective until at least 30 days after receipt by the
Administrative Agent and the Lenders of written notice thereof, (iii) name the
Administrative Agent as loss payee of each such policy, (iv) name the
Administrative Agent and the Lenders as insured to the extent of their interests
under each such policy and (v) be reasonably satisfactory in all material
respects to the Administrative Agent. The Grantor shall deliver to the
Administrative Agent and each Lender upon request, full information as to the
insurance carried, including certified copies of policies and certificates of
insurance from a recognized insurance broker reasonably acceptable to the
Administrative Agent.

                  (n) FURTHER IDENTIFICATION OF COLLATERAL. The Grantor will
furnish to the Administrative Agent and the Lenders from time to time statements
and schedules further identifying and describing the Collateral and such other
reports in connection with the Collateral as the Administrative Agent may
reasonably request, all in reasonable detail.

                  (o) NOTICES. The Grantor will advise the Administrative Agent
promptly, in reasonable detail, at its address set forth in the Credit
Agreement, (i) of any Lien (other than Liens created hereby or permitted under
the Credit Agreement) on, or claim asserted against, any of the Collateral and
(ii) of the occurrence of any other event which could reasonably be expected to
have a material adverse effect on the aggregate value of the Collateral or on
the Liens created hereunder.

                  (p) CHANGES IN LOCATIONS, NAME, ETC. Unless the Grantor gives
30 days' prior written notice to the Administrative Agent, the Grantor will not
(i) change the location of its chief executive office/chief place of business
from that specified in Section 4(f) or remove its books and records from the
location specified in Section 4(c), (ii) permit any of the Inventory or
Equipment to be kept at a location other than those listed on Schedule I hereto
or (iii) change its name, identity or corporate structure to such an extent that
any financing statement filed by the Administrative Agent in connection with
this Security Agreement would become seriously misleading.

                  6.       ADMINISTRATIVE AGENT'S APPOINTMENT AS
ATTORNEY-IN-FACT.

                  (a) POWERS. The Grantor hereby irrevocably constitutes and
appoints the Administrative Agent and any officer or agent thereof, with full
power of substitution, as its true and lawful attorney-in-fact with full
irrevocable power and authority in the place and stead of the


                                       10

<PAGE>


Grantor and in the name of the Grantor or in its own name, from time to time
in the Administrative Agent's discretion, for the purpose of carrying out the
terms of this Security Agreement, to take any and all appropriate action and
to execute any and all documents and instruments which may be necessary or
desirable to accomplish the purposes of this Security Agreement, and, without
limiting the generality of the foregoing, the Grantor hereby gives the
Administrative Agent the power and right, on behalf of the Grantor, without
notice to or assent by the Grantor, to do the following:

                  (i) in the case of any Account, at any time when the authority
         of the Grantor to collect the Accounts has been curtailed or terminated
         pursuant to the first sentence of Section 3(c), or in the case of any
         other Collateral, at any time when any Event of Default shall have
         occurred and is continuing, in the name of the Grantor or its own name,
         or otherwise, to take possession of and endorse and collect any checks,
         drafts, notes, acceptances or other instruments for the payment of
         moneys due under any Account, Instrument, General Intangible or
         Contract or with respect to any other Collateral and to file any claim
         or to take any other action or proceeding in any court of law or equity
         or otherwise deemed appropriate by the Administrative Agent for the
         purpose of collecting any and all such moneys due under any Account,
         Instrument, General Intangible or Contract or with respect to any other
         Collateral whenever payable;

                  (ii) to pay or discharge taxes and Liens levied or placed on
         or threatened against the Collateral, to effect any repairs or any
         insurance called for by the terms of this Security Agreement and to pay
         all or any part of the premiums therefor and the costs thereof; and

                  (iii) upon the occurrence and during the continuance of any
         Event of Default, (A) to direct any party liable for any payment under
         any of the Collateral to make payment of any and all moneys due or to
         become due thereunder directly to the Administrative Agent or as the
         Administrative Agent shall direct; (B) to ask or demand for, collect,
         receive payment of and receipt for, any and all moneys, claims and
         other amounts due or to become due at any time in respect of or arising
         out of any Collateral; (C) to sign and endorse any invoices, freight or
         express bills, bills of lading, storage or warehouse receipts, drafts
         against debtors, assignments, verifications, notices and other
         documents in connection with any of the Collateral; (D) to commence and
         prosecute any suits, actions or proceedings at law or in equity in any
         court of competent jurisdiction to collect the Collateral or any
         thereof and to enforce any other right in respect of any Collateral;
         (E) to defend any suit, action or proceeding brought against the
         Grantor with respect to any Collateral; (F) to settle, compromise or
         adjust any suit, action or proceeding described in clause (E) above
         and, in connection therewith, to give such discharges or releases as
         the Administrative Agent may deem appropriate; and (G) generally, to
         sell, transfer, pledge and make any agreement with respect to or
         otherwise deal with any of the Collateral as fully and completely as
         though the Administrative Agent were the absolute owner thereof for all
         purposes, and to do, at the Administrative Agent's option and the
         Grantor's expense, at any time, or from time to time, all acts and
         things which the Administrative Agent deems necessary to protect,
         preserve or realize upon the Collateral and the Administrative Agent's
         and the Lenders' Liens thereon and to effect the intent of this
         Security Agreement, all as fully and effectively as the Grantor might
         do.


                                      11

<PAGE>


The Grantor 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 shall be irrevocable.

                  (b) OTHER POWERS. The Grantor also authorizes the
Administrative Agent and the Lenders, at any time and from time to time, to
execute, in connection with the sale provided for in this SECTION 6 or in
SECTION 9 hereof, any endorsements, assignments or other instruments of
conveyance or transfer with respect to the Collateral.

                  (c) NO DUTY ON ADMINISTRATIVE AGENT OR LENDERS' PART. The
powers conferred on the Administrative Agent and the Lenders hereunder are
solely to protect the Administrative Agent's and the Lenders' interests in the
Collateral and shall not impose any duty upon the Administrative Agent or any
Lender to exercise any such powers. The Administrative Agent and the Lenders
shall be accountable only for amounts that they actually receive as a result of
the exercise of such powers, and neither they nor any of their officers,
directors, employees or agents shall be responsible to the Grantor for any act
or failure to act hereunder, except for their own gross negligence or willful
misconduct.

                  7. PERFORMANCE BY ADMINISTRATIVE AGENT OF GRANTOR'S
OBLIGATIONS. If the Grantor fails to perform or comply with any of its
agreements contained herein and the Administrative Agent, as provided for by the
terms of this Security Agreement, shall itself perform or comply, or otherwise
cause performance or compliance, with such agreement, the expenses of the
Administrative Agent incurred in connection with such performance or compliance,
together with interest thereon at a rate per annum 2% above the Alternate Base
Rate, shall be payable by the Grantor to the Administrative Agent on demand and
shall constitute Obligations secured hereby.

                  8. PROCEEDS. In addition to the rights of the Administrative
Agent and the Lenders specified in Section 3(c) with respect to payments of
Accounts, it is agreed that if an Event of Default shall occur and be continuing
(a) upon written notice by the Administrative Agent to the Grantor, all Proceeds
received by the Grantor consisting of cash, checks and other near-cash items
shall be held by the Grantor in trust for the Administrative Agent and the
Lenders, segregated from other funds of the Grantor, and, forthwith upon receipt
by the Grantor, shall be turned over to the Administrative Agent in the exact
form received by the Grantor (duly endorsed by the Grantor to the Administrative
Agent, if required), and (b) any and all such Proceeds received by the
Administrative Agent (whether from the Grantor or otherwise) may, in the sole
discretion of the Administrative Agent, (i) be held by the Administrative Agent
for the ratable benefit of the Lenders as collateral security for the Guaranteed
Obligations, and/or (ii) then or at any time thereafter either (x) be applied by
the Administrative Agent for the ratable benefit of the Lenders against the
Guarantee Obligations (whether matured or unmatured), such application to be in
such order as the Administrative Agent shall elect, or (y) at the sole
discretion of the Administrative Agent, be available for use by the Grantor in
the operation of its business. Any balance of such Proceeds remaining after the
Obligations shall have been paid in full and the Commitments shall have been
terminated shall be paid over to the Grantor or to whomsoever may be lawfully
entitled to receive the same.

                  9. REMEDIES. If an Event of Default shall occur and be
continuing, the Administrative Agent, on behalf of the Lenders, may exercise, in
addition to all other rights and


                                      12

<PAGE>


remedies granted to them in this Security Agreement and in any other
instrument or agreement securing, evidencing or relating to the Obligations,
all rights and remedies of a secured party under the Code. Without limiting
the generality of the foregoing, the Administrative Agent, without demand of
performance or other demand, presentment, protest, advertisement or notice of
any kind (except any notice required by law referred to below) to or upon the
Grantor, any guarantor, or any other Person (all and each of which demands,
defenses, advertisements and notices being hereby waived to the maximum
extent permitted by applicable law), may in such circumstances forthwith
collect, receive, appropriate and realize upon the Collateral, or any part
thereof, and/or may forthwith sell, lease, assign, give option or options to
purchase, or otherwise dispose of and deliver the Collateral or any part
thereof (or contract to do any of the foregoing), in one or more parcels at
public or private sale or sales, at any exchange, broker's board or office of
the Administrative Agent or any Lender or elsewhere upon such terms and
conditions as it may deem advisable and at such prices as it may deem best,
for cash or on credit or for future delivery without assumption of any credit
risk. The Administrative Agent or any Lender shall have the right upon any
such public sale or sales, and, to the extent permitted by applicable law,
upon any such private sale or sales, to purchase the whole or any part of the
Collateral so sold, free of any right or equity of redemption in the Grantor,
which right or equity is hereby waived or released to the maximum extent
permitted by applicable law. The Grantor further agrees, at the
Administrative Agent's request, to assemble the Collateral and make it
available to the Administrative Agent at such places as the Administrative
Agent shall reasonably select, whether at the Grantor's premises or
elsewhere. The Administrative Agent shall apply the net proceeds of any such
collection, recovery, receipt, appropriation, realization or sale, after
deducting all reasonable costs and expenses of every kind incurred therein or
incidental to the care or safekeeping of any of the Collateral or in any way
relating to the Collateral or the rights of the Administrative Agent and the
Lenders hereunder, including, without limitation, reasonable attorneys' fees
and disbursements, to the payment in whole or in part of the Obligations, in
such order as the Administrative Agent may elect, and only after such
application and after the payment by the Administrative Agent of any other
amount required by any provision of law, including, without limitation,
Section 9-504(i)(c) of the Code, need the Administrative Agent account for
the surplus, if any, to the Grantor. To the extent permitted by applicable
law, the Grantor waives all claims, damages and demands it may acquire
against the Administrative Agent or any Lender arising out of the exercise by
them of any rights hereunder. If any notice of a proposed sale or other
disposition of Collateral shall be required by law, such notice shall be
deemed reasonable and proper if given at least 10 days before such sale or
other disposition. The Grantor shall remain liable for any deficiency if the
proceeds of any sale or other disposition of the Collateral are insufficient
to pay the Obligations and the fees and disbursements of any attorneys
employed by the Administrative Agent or any Lender to collect such deficiency.

                  10. LIMITATION ON DUTIES REGARDING PRESERVATION OF COLLATERAL.
The Administrative Agent's sole duty with respect to the custody, safekeeping
and physical preservation of the Collateral in its possession, under Section
9-207 of the Code or otherwise, shall be to deal with it in the same manner as
the Administrative Agent deals with similar property for its own account.
Neither the Administrative Agent, any Lender, nor any of their respective
directors, officers, employees or agents shall be liable for failure to demand,
collect or realize upon all or any part of the Collateral or for any delay in
doing so or shall be under any obligation to sell or otherwise dispose of any
Collateral upon the request of the Grantor or otherwise.


                                       13

<PAGE>


                  11. POWERS COUPLED WITH AN INTEREST. All authorizations and
agencies herein contained with respect to the Collateral are irrevocable and
powers coupled with an interest.

                  12. LIMITATION ON LINES OF BUSINESS. Nothing in this Security
Agreement shall be deemed or construed as modifying in any way the restrictions
on the Grantor's activities as set forth in Section 6.14 of the Credit
Agreement.

                  13. SEVERABILITY. Any provision of this Security Agreement
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

                  14. SECTION HEADINGS. The section headings used in this
Security Agreement are for convenience of reference only and are not to affect
the construction hereof or be taken into consideration in the interpretation
hereof.

                  15. NO WAIVER; CUMULATIVE REMEDIES. Neither the Administrative
Agent nor any Lender shall by any act (except by a written instrument pursuant
to SECTION 16), delay, indulgence, omission or otherwise be deemed to have
waived any right or remedy hereunder or to have acquiesced in any Default or
Event of Default or in any breach of any of the terms and conditions hereof. No
failure to exercise, nor any delay in exercising, on the part of the
Administrative Agent or any Lender, any right, power or privilege hereunder

amended, supplemented or otherwise modified since the respective dates

is a true, complete and correct copy of the schedule of sources and uses

continuing as of the date hereof or after giving effect to the making of the
Loans on the date hereof.

                  7. There are no liquidation or dissolution proceedings pending
or to my knowledge threatened against the Parent, nor has any other event
occurred affecting or threatening the existence of the Parent.

                              W I T N E S S E T H:

                  WHEREAS, this Commitment Transfer Supplement is being executed

                  NOW, THEREFORE, the parties hereto hereby agree as follows:

                  1. Upon receipt by the Administrative Agent of (i) a
counterpart of this Commitment Transfer Supplement, to which is attached a fully
completed Schedule I and Schedule II, and which has been executed by the
Transferor Bank, each Purchasing Bank and any other person required by the
Amended and Restated Credit Agreement to consent to the transfer evidenced by

the Commitments and the presently outstanding Loans and other amounts owing to
the Transferor Bank under the Amended and Restated Credit Agreement and its
Note(s) together with all instruments, documents and collateral security
pertaining thereto.

                  3. The Transferor Bank has made arrangements with each
Purchasing Bank with respect to (i) the portion, if any, to be paid, and the
date or dates for payment, by the Transferor Bank to such Purchasing Bank of any

Note(s) shall, instead, be payable to or for the account of the Transferor Bank
and the Purchasing Banks, as the case may be, in accordance with their
respective interests as reflected in this Commitment Transfer Supplement.

                  (b) All interest, fees and other amounts that would otherwise
accrue for the account of the Transferor Bank from and after the Transfer

Note(s) shall, instead, accrue for the account of, and be payable to, the
Transferor Bank and the Purchasing Banks, as the case may be, in accordance with
their respective interests as reflected in this Commitment Transfer Supplement.
In the event that any amount of interest, fees or other amounts accruing prior
to the Transfer Effective Date was included in the Purchase Price paid by any
Purchasing Bank, the Transferor Bank and each Purchasing Bank will make
appropriate arrangements for payment by the Transferor Bank to such Purchasing

the Borrower will deliver to the Administrative Agent a new Note or Notes of
the Borrower for each Purchasing Bank, and (if the Transferor Bank shall,

Effective Date, the Administrative Agent will send to each of the Transferor
Bank and the Purchasing Banks its new Note(s) and will send to the Borrower
the superseded Note(s) of the Transferor Bank, marked "cancelled".

                  6. Concurrently with the execution and delivery hereof, the
Transferor Bank will provide to each Purchasing Bank (if it is not already a
Lender party to the Amended and Restated Credit Agreement) conformed copies of
all documents delivered to such Transferor Bank on the Original Closing Date and
the Effective Date in satisfaction of the conditions precedent set forth in the
Amended and Restated Credit Agreement.

other party, it will execute and deliver such further documents and do such
further acts and things as such other party may reasonably request in order to
effect the purposes of this Commitment Transfer Supplement.

Supplement, the Transferor Bank and each Purchasing Bank confirm to and agree
with each other and the Administrative Agent and the Lenders as follows: (i)
other than the representation and warranty that it is the legal and beneficial
owner of the interest being assigned hereby free and clear of any adverse claim,
the Transferor Bank makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or representations
made in or in connection with the Amended and Restated Credit Agreement or the

hereto; (iii) each Purchasing Bank confirms that it has received a copy of the
Amended and Restated Credit Agreement, together with copies of the financial
statements referred to in Section 3.1 of the Amended and Restated Credit
Agreement, the financial statements delivered pursuant to Section 5.1 of the
Amended and Restated Credit Agreement, if any, and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into this Commitment Transfer Supplement; (iv) each Purchasing
Bank will, independently and without reliance upon the Administrative Agent, the
Transferor Bank or any other Lender and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
decisions in taking of not taking action under the Amended and Restated Credit
Agreement; (v) each Purchasing Bank appoints and authorizes the Administrative
Agent to take such action as agent on its behalf and to exercise such powers
under the Amended and Restated Credit Agreement and the other Loan Documents as
are delegated to the Administrative Agent by the terms thereof, together with
such powers as are reasonably incidental thereto, all in accordance


                                       3

<PAGE>

with Article 10 of the Amended and Restated Credit Agreement; and (vi) each
Purchasing Bank agrees that it will perform in accordance with their terms
all the obligations which, by the terms of the Amended and Restated Credit
Agreement, are required to be performed by it as a Lender.

                  9. Each Purchasing Bank agrees to comply with Section 2.18(b)
of the Amended and Restated Credit Agreement to the same extent as if it were
one of the original Lenders signatory to the Amended and Restated Credit
Agreement.

                  10. Schedule II hereto sets forth the revised Commitment and
Commitment Percentage of the Transferor Bank and each Purchasing Bank as well as

                  relate specifically to a particular Security Holder such as
                  indemnification with respect to representations and warranties
                  given by a Security Holder regarding such Security Holder's
                  title to and ownership of a Security, as to which obligations
                  each such Security Holder shall be solely liable); provided
                  that no Security Holder shall be obligated in connection with
                  a Sale of the Company to agree to indemnify or hold harmless
                  the prospective transferee(s) with respect to an amount in
                  excess of the net cash proceeds to be paid to such Security
                  Holder in connection with such Sale of the Company.

                  (b) CONDITION. The obligations of the Security Holders with
respect to a Sale of the Company are subject to a satisfaction of the condition
that, upon the consummation of the Sale of the Company, including any related
redemptions, all of the holders of a particular class or series of securities
shall receive the same form and amount of consideration per share, unit or
amount of securities or if any holders of a particular type, class or series of
securities are given an option as to the form and amount of consideration to be
received, all holders of such type, class or series will be given the same
option.

                  (c) PURCHASER REPRESENTATIVE. If the Company enters into any
negotiation or transaction for which Rule 506 under the Securities Act (or any
similar rule then in effect) may be available with respect to such negotiation
or transaction (including a merger, consolidation or other reorganization), each
Security Holder that is not an "accredited investor" (within the meaning of Rule
501(a) of the Securities Act) will, at the request of Company, appoint a
purchaser representative (as such term is defined in Rule 501 under the
Securities Act) approved by Company and Company will pay the fees of such
purchaser representative. If any such Security


<PAGE>


Holder declines to appoint the purchaser representative approved by Company
such Security Holder will appoint another purchaser representative, and such
Security Holder will be responsible for the fees of the purchaser
representative so appointed.

                  (d) COSTS. Each Security Holder will bear its or his pro-rata
share (based upon the relative amount of proceeds received with respect to
securities sold) of the reasonable costs of any sale of securities pursuant to a
Sale of the Company to the extent such costs are incurred for the benefit of all
Security Holders and are not otherwise paid by Company or the acquiring party.
Costs incurred by or on behalf of a Security Holder for its or his sole benefit
will not be considered costs of the transaction hereunder.

                  (e) TERMINATION OF RESTRICTIONS. The restrictions set forth
above shall continue with respect to each security until the earlier of (i) the
date on which such security has been transferred in a Public Sale, or (ii) the
consummation of a Qualified IPO by the Company. Notwithstanding any other
provision of this Agreement, except as set forth in the preceding sentence, the
restrictions set forth above shall continue to be applicable to all securities
after any transfer and no transfer shall be consummated, or be deemed
consummated, for any purpose unless each transferee of such securities shall
have agreed in a writing, in form and substance satisfactory to the Company
delivered to the Company prior to such transfer, to be bound by the provisions
of this Agreement affecting the securities so transferred.

2.       EXCHANGE OFFER

                  (a) To the extent not prohibited by any applicable law, each
of the Issuers agrees to use its reasonable best efforts to file or cause to be
filed with the Commission no later than the Filing Date, an offer to exchange
(the "EXCHANGE OFFER") any and all of the Registrable Notes (other than Private
Exchange Notes, if any) for a like aggregate principal amount of debt securities
of the Company that are identical in all material respects to the Notes (the
"EXCHANGE NOTES") (and that are entitled to the benefits of the Indenture or a
trust indenture that is identical in all material respects to the Indenture
(other than such changes to the Indenture or any such identical trust indenture
as are necessary to comply with any requirements of the Commission to effect or
maintain the qualification thereof under the TIA) and that, in either case, has
been qualified under the TIA), except that the Exchange Notes shall have been
registered pursuant to an effective Registration Statement under the Securities


<PAGE>

                                        -6-

Act and shall contain no restrictive legend thereon. The Exchange Offer shall be
registered under the Securities Act on the appropriate form (the "EXCHANGE
REGISTRATION STATEMENT") and shall comply with all applicable tender offer rules
and regulations under the Exchange Act. Each of the Issuers agrees to use its
reasonable best efforts to (x) cause the Exchange Registration Statement to be
declared effective under the Securities Act on or before the Effectiveness Date;
(y) keep the Exchange Offer open for at least 20 Business Days (or longer if
required by applicable law) after the date that notice of the Exchange Offer is
first mailed to Holders; and (z) consummate the Exchange Offer on or prior to
the 30th day following the date on which the Exchange Registration Statement is
declared effective. If after such Exchange Registration Statement is initially
declared effective by the Commission, the Exchange Offer or the issuance of the
Exchange Notes thereunder is interfered with by any stop order, injunction or
other order or requirement of the Commission or any other governmental agency or
court, such Exchange Registration Statement shall be deemed not to have become
effective for purposes of this Agreement. Each Holder who participates in the
Exchange Offer will be required to represent that any Exchange Notes received by
it will be acquired in the ordinary course of its business, that at the time of
the consummation of the Exchange Offer such Holder will have no arrangement or
understanding with any Person to participate in the distribution of the Exchange
Notes, that such Holder is not an affiliate of any Issuer within the meaning of
the Securities Act, and any additional representations that in the written
opinion of counsel to the Issuers are necessary under then-existing
interpretations of the Commission in order for the Exchange Registration
Statement to be declared effective. Upon consummation of the Exchange Offer in
accordance with this Section 2, the provisions of this Agreement shall continue
to apply, MUTATIS MUTANDIS, solely with respect to Registrable Notes that are
Private Exchange Notes and Exchange Notes held by Participating Broker-Dealers,
and the Issuers shall have no further obligation to register Registrable Notes
(other than Private Exchange Notes and other than in respect of any Exchange
Notes as to which clause 2(c)(iv) hereof applies) pursuant to Section 3 of this
Agreement.

                  (b) The Issuers shall indicate in a "Plan of Distribution"
section contained in the Prospectus contained in the Exchange Registration
Statement that any Participating Broker-Dealer may exchange such Notes pursuant
to the Exchange Offer; however, such Participating Broker-Dealer may be deemed
to be an "underwriter" within the meaning of the Securities Act and must,
therefore, deliver a prospectus meeting the requirements of the Securities Act
in connection with any resales of the Exchange Securities received by such
Participating Broker-Dealer in the Exchange Offer, which prospectus delivery
requirement may be satisfied by the delivery by such Participating Broker-Dealer
of the Prospectus contained in the Exchange Registration Statement. Such "Plan
of Distribution" section shall also contain all other information with respect
to such resales by Participating Broker-Dealers that the Commission may require
in order to permit such resales pursuant thereto, but such


<PAGE>

                                        -7-

"Plan of Distribution" section shall not name any such Participating
Broker-Dealer or disclose the amount of Exchange Notes held by any such
Participating Broker-Dealer except to the extent required by the Commission as a
result of a change in policy announced after the date of this Agreement.

                  Each of the Issuers shall use its reasonable best efforts to
keep the Exchange Registration Statement effective and to amend and supplement
the Prospectus contained therein, in order to permit such Prospectus to be
lawfully delivered by all Persons subject to the prospectus delivery
requirements of the Securities Act for such period of time beginning when the
Exchange Notes are first issued in the Exchange Offer and ending upon the
earlier of the expiration of the 180th day after the Exchange Offer has been
completed and such Persons are no longer required to comply with the prospectus
delivery requirements in connection with offers and sales of the Exchange Notes
(the "APPLICABLE PERIOD").

                  If, upon consummation of the Exchange Offer, any Initial
Purchaser holds any Notes acquired by it and having the status of an unsold
allotment in the initial distribution, the Issuers, upon the written request of
any Initial Purchaser and an opinion of outside counsel for such Initial
Purchaser, reasonably satisfactory in form and substance to outside counsel of
the Company, to the effect that such exchange does not require compliance with
the registration requirements of the Securities Act, shall, simultaneously with
the delivery of the Exchange Notes in the Exchange Offer, issue and deliver to
such Initial Purchaser, in exchange (the "PRIVATE EXCHANGE") for the Notes held
by such Initial Purchaser, a like principal amount of debt securities of the
Company that are identical in all material respects to the Exchange Notes except
for the existence of restrictions on transfer thereof under the Securities Act
and securities laws of the several states of the U.S. (the "PRIVATE EXCHANGE
NOTES") (and which are issued pursuant to the same indenture as the Exchange
Notes). The Company will use its reasonable best efforts to seek to cause the
CUSIP Service Bureau to issue the same CUSIP number for the Private Exchange
Notes as for the Exchange Notes. Interest on the Exchange Notes and Private
Exchange Notes will accrue from the last interest payment date on which interest
was paid on the Notes surrendered in exchange therefor or, if no interest has
been paid on the Notes, from the Issue Date.

                  In connection with the Exchange Offer, the Issuers shall:

                    (1) mail to each Holder a copy of the Prospectus forming
         part of the Exchange Registration Statement, together with an
         appropriate letter of transmittal and related documents;


<PAGE>

                                        -8-

                    (2) utilize the services of a depositary for the Exchange
         Offer with an address in the Borough of Manhattan, The City of New
         York, which may be the Trustee or an affiliate thereof;

                    (3) permit Holders to withdraw tendered Registrable Notes at
         any time prior to the close of business, New York time, on the last
         Business Day on which the Exchange Offer shall remain open; and

                    (4) otherwise comply in all material respects with all
applicable laws.

                  As soon as practicable after the close of the Exchange Offer
or the Private Exchange, as the case may be, the Issuers shall:

                    (1) accept for exchange all Registrable Notes validly
         tendered and not validly withdrawn pursuant to the Exchange Offer
         or the Private Exchange;

                    (2) deliver, or cause to be delivered, to the Trustee for
         cancellation all Registrable Notes so accepted for exchange; and

                    (3) cause the Trustee to authenticate and deliver promptly
         to each Holder tendering such Registrable Notes, Exchange Notes or
         Private Exchange Notes, as the case may be, equal in principal amount
         to the Notes of such Holder so accepted for exchange.

                  The Exchange Notes and the Private Exchange Notes may be
issued under (i) the Indenture or (ii) an indenture identical in all material
respects to the Indenture, which in either event will provide that the Exchange
Notes will not be subject to the transfer restrictions set forth in the
Indenture and that the Exchange Notes, the Private Exchange Notes and the Notes,
if any, will vote and consent together on all matters as one class and that none
of the Exchange Notes, the Private Exchange Notes or the Notes, if any, will
have the right to vote or consent as a separate class on any matter.

                  (c) If, (i) because of any change in law or in currently
prevailing interpretations of the staff of the Commission, the Company is not
permitted to effect an Exchange Offer, (ii) the Exchange Offer is not
consummated within 180 days of the Issue Date, (iii) any holder of Private
Exchange Notes so requests in writing to the Company or (iv) in the case of any
Holder that participates in the Exchange Offer (and tenders its Registrable
Notes prior to the expiration thereof), such Holder does not receive Exchange
Notes on the date of the exchange that may be sold without restriction under
federal securities laws (other than due solely to the status of such Holder as
an affiliate of any Issuer within the


<PAGE>

                                        -9-

meaning of the Securities Act) and so notifies the Company within 30 days
following the consummation of the Exchange Offer (and providing a reasonable
basis for its conclusions), in the case of each of clauses (i)-(iv), then the
Issuers shall promptly deliver to the Holders and the Trustee written notice
thereof (the "SHELF NOTICE") and shall use its reasonable best efforts to file,
or cause to be filed, a Shelf Registration pursuant to Section 3.

3.       SHELF REGISTRATION

                  If a Shelf Notice is delivered as contemplated by Section
2(c), then:

                  (a) SHELF REGISTRATION. Each of the Issuers shall use its
reasonable best efforts to file with the Commission as promptly as reasonably
practicable a Registration Statement for an offering to be made on a continuous
basis pursuant to Rule 415 covering all of the Registrable Notes (the "INITIAL
SHELF REGISTRATION"). If the Issuers shall not have yet filed the Exchange
Registration Statement, each of the Issuers shall use its reasonable best
efforts to file with the Commission the Initial Shelf Registration on or prior
to the Filing Date and shall use its best efforts to cause such Initial Shelf
Registration to be declared effective under the Securities Act on or prior to
the Effectiveness Date, which shall be determined as if the Issuers received a
Shelf Notice relating to such Initial Shelf Registration on the Filing Date.
Otherwise, each of the Issuers shall use its reasonable best efforts to file
with the Commission the Initial Shelf Registration within 45 days of the
delivery of the Shelf Notice and shall use its best efforts to cause such Shelf
Registration to be declared effective under the Securities Act on or prior to
the Effectiveness Date. The Initial Shelf Registration shall be on Form S-1 or
another appropriate form permitting registration of such Registrable Notes for
resale by Holders in the manner or manners designated by them (including,
without limitation, one or more underwritten offerings). The Issuers shall not
permit any securities other than the Registrable Notes to be included in any
Shelf Registration. Each of the Issuers shall use its best efforts to keep the
Initial Shelf Registration continuously effective under the Securities Act until
the date that is 24 months from the Issue Date (or, if Rule 144(k) under the
Securities Act is amended to permit unlimited resales by non-affiliates within a
lesser period, such lesser period) (the "EFFECTIVENESS PERIOD") or such shorter
period ending when (i) all Registrable Notes covered by the Initial Shelf
Registration have been sold in the manner set forth and as contemplated in the
Initial Shelf Registration or (ii) a Subsequent Shelf Registration covering all
of the Registrable Notes has been declared effective under the Securities Act.

                  (b) SUBSEQUENT SHELF REGISTRATIONS. If the Initial Shelf
Registration or any Subsequent Shelf Registration ceases to be effective for any
reason at any time during the Effectiveness Period (other than because of the
sale of all of the securities registered


<PAGE>

                                        -10-

thereunder), each of the Issuers shall use its best efforts to obtain the prompt
withdrawal of any order suspending the effectiveness thereof, and in any event
shall within 30 days of such cessation of effectiveness amend the Shelf
Registration in a manner to obtain the withdrawal of the order suspending the
effectiveness thereof, or file an additional "shelf" Registration Statement
pursuant to Rule 415 covering all of the Registrable Notes (a "SUBSEQUENT SHELF
REGISTRATION"). If a Subsequent Shelf Registration is filed, each of the Issuers
shall use its best efforts to cause the Subsequent Shelf Registration to be
declared effective as soon as practicable after such filing and to keep such
Subsequent Shelf Registration continuously effective for the remainder of the
Effectiveness Period. As used herein the term "SHELF REGISTRATION" means the
Initial Shelf Registration and any Subsequent Shelf Registration.

                  (c) SUPPLEMENTS AND AMENDMENTS. Each of the Issuers shall
promptly supplement and amend any Shelf Registration if required by the rules,
regulations or instructions applicable to the registration form used for such
Shelf Registration, if required by the Securities Act, or if reasonably
requested by the Holders of a majority in aggregate principal amount of the
Registrable Notes covered by such Shelf Registration or by any underwriter of
such Registrable Notes, in each case, with the Issuers' consent, which consent
shall not be unreasonably withheld or delayed.

4.       ADDITIONAL INTEREST

                  (a) The Issuers and the Initial Purchasers agree that the
Holders of Registrable Notes will suffer damages if the Issuers fail to fulfill
their respective obligations under Section 2 or Section 3 hereof and that it
would not be feasible to ascertain the extent of such damages with precision.
Accordingly, the Issuers jointly and severally agree to pay, as liquidated
damages, additional interest on the Registrable Notes ("ADDITIONAL INTEREST")
under the circumstances and to the extent set forth below (each of which shall
be given independent effect):

                    (i) if (A) neither the Exchange Registration Statement nor
         the Initial Shelf Registration has been filed on or prior to the Filing
         Date or (B) notwithstanding that the Issuers have filed the Exchange
         Offer Registration Statement and have consummated or will consummate an
         Exchange Offer, the Issuers are required to file a Shelf Registration
         and such Shelf Registration is not filed on or prior to the 45th day
         after delivery of the Shelf Notice, then, in the case of subclause (A),
         commencing on the day after the Filing Date or, in the case of
         subclause (B), commencing on the 46th day following delivery of the
         Shelf Notice, Additional Interest shall accrue on the Registrable Notes
         over and above the stated interest at a rate of 0.50% per annum for the
         first 90 days immediately following the Filing Date or such 45th day,
         as the case may


<PAGE>

                                        -11-

         be, such Additional Interest rate increasing by an additional 0.25%
         per annum at the beginning of each subsequent 90-day period;

                   (ii) if (A) neither the Exchange Registration Statement nor
         the Initial Shelf Registration is declared effective on or prior to the
         Effectiveness Date applicable thereto or (B) notwithstanding that the
         Issuers have filed the Exchange Offer Registration Statement and have
         consummated or will consummate an Exchange Offer, the Issuers are
         required to file a Shelf Registration and such Shelf Registration is
         not declared effective by the Commission on or prior to the applicable
         Effectiveness Date, then, commencing on the day after such applicable
         Effectiveness Date, Additional Interest shall accrue on the Registrable
         Notes over and above the stated interest at a rate of 0.50% per annum
         for the first 90 days immediately following the day after the
         applicable Effectiveness Date, such Additional Interest rate increasing
         by an additional 0.25% per annum at the beginning of each subsequent
         90-day period; and

                  (iii) if (A) the Issuers have not exchanged Exchange Notes for
         all Notes validly tendered in accordance with the terms of the Exchange
         Offer on or prior to the 180th day after the Issue Date, (B) the
         Exchange Registration Statement ceases to be effective prior to
         consummation of the Exchange Offer or (C) if applicable, a Shelf
         Registration has been declared effective and such Shelf Registration
         ceases to be effective at any time during the Effectiveness Period,
         then Additional Interest shall accrue on the Registrable Notes over and
         above the stated interest at a rate of 0.50% per annum for the first 90
         days commencing on the (x) 181st day after the Issue Date in the case
         of (A) above or (y) the day such Exchange Registration Statement or
         Shelf Registration ceases to be effective in the case of (B) and (C)
         above, such Additional Interest rate increasing by an additional 0.25%
         per annum at the beginning of each such subsequent 90-day period;

PROVIDED, HOWEVER, that the Additional Interest rate on the Registrable Notes
may not exceed in the aggregate 2.0% per annum; PROVIDED FURTHER that (1) upon
the filing of the Exchange Registration Statement or each Shelf Registration (in
the case of (i) above), (2) upon the effectiveness of the Exchange Registration
Statement or each Shelf Registration, as the case may be (in the case of (ii)
above), or (3) upon the exchange of Exchange Notes for all Registrable Notes
tendered (in the case of (iii)(A) above) or upon the effectiveness of an
Exchange Registration Statement or Shelf Registration which had ceased to remain
effective (in the case of (iii)(B) and (C) above), Additional Interest on any
Registrable Notes then accruing Additional Interest as a result of such clause
(or the relevant subclause thereof), as the case may be, shall cease to accrue.


<PAGE>

                                        -12-

                  (b) The Issuers shall notify the Trustee within three Business
Day after each and every date on which an event occurs in respect of which
Additional Interest is required to be paid (an "EVENT DATE"). Any amounts of
Additional Interest due pursuant to (a)(i), (a)(ii) or (a)(iii) of this Section
4 will be payable in cash semi-annually on each regular interest payment date
specified in the Indenture (to the Holders of Registrable Notes of record on the
regular record date therefor (as specified in the Indenture) immediately
preceding such dates), commencing with the first such regular interest payment
date occurring after any such Additional Interest commences to accrue. The
amount of Additional Interest will be determined by multiplying the applicable
Additional Interest rate by the principal amount of the Notes subject thereto,
multiplied by a fraction, the numerator of which is the number of days such
Additional Interest rate was applicable during such period (determined on the
basis of a 360-day year comprised of twelve 30-day months), and the denominator
of which is 360.

5.       REGISTRATION PROCEDURES

                  In connection with the filing of any Registration Statement
pursuant to Sections 2 or 3 hereof, each of the Issuers shall use its reasonable
best efforts to effect such registrations to permit the sale of such securities
covered thereby in accordance with the intended method or methods of disposition
thereof, and pursuant thereto and in connection with any Registration Statement
filed by each of the Issuers hereunder, each of the Issuers shall use its
reasonable best efforts to:

                  (a) Prepare and file with the Commission prior to the Filing
Date, the Exchange Registration Statement or if the Exchange Registration
Statement is not filed or is unavailable, a Shelf Registration as prescribed by
Section 2 or 3, and use its best efforts to cause each such Registration
Statement to become effective and remain effective as provided herein; PROVIDED
that, if (1) a Shelf Registration is filed pursuant to Section 3, or (2) a
Prospectus contained in an Exchange Registration Statement filed pursuant to
Section 2 is required to be delivered under the Securities Act by any
Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period and has advised the Issuers that it is a Participating
Broker-Dealer, before filing any Registration Statement or Prospectus or any
amendments or supplements thereto, the Issuers shall, if requested, furnish to
and afford the Holders of the Registrable Notes to be registered pursuant to
such Shelf Registration or each such Participating Broker-Dealer, as the case
may be, covered by such Registration Statement, their counsel and the managing
underwriters, if any, a reasonable opportunity to review copies of all such
documents (including copies of any documents to be incorporated by reference
therein and all exhibits thereto) proposed to be filed (in each case at least
five Business Days prior to such filing). The Issuers shall not file any such
Registration Statement or Prospectus or any amendments or supplements thereto if
the Holders of a majority in aggregate principal


<PAGE>
                                        -13-

amount of the Registrable Notes covered by such Registration Statement, or any
such Participating Broker-Dealer, as the case may be, their counsel, or the
managing underwriters, if any, shall reasonably object.

                  (b) Prepare and file with the Commission such amendments and
post-effective amendments to each Shelf Registration or Exchange Registration
Statement, as the case may be, as may be necessary to keep such Registration
Statement continuously effective for the Effectiveness Period or the Applicable
Period, as the case may be; cause the related Prospectus to be supplemented, if
requested by the Commission, by any Prospectus supplement required by applicable
law, and as so supplemented to be filed pursuant to Rule 424 (or any similar
provisions then in force) under the Securities Act; and comply with the
provisions of the Securities Act and the Exchange Act applicable to it with
respect to the disposition of all securities covered by such Registration
Statement as so amended or in such Prospectus as so supplemented and with
respect to the subsequent resale of any securities being sold by a Participating
Broker-Dealer covered by any such Prospectus.

                  (c) If (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is required to be delivered under the Securities Act by
any Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period from whom the Issuers have received written notice that it
will be a Participating Broker-Dealer, notify the selling Holders of Registrable
Notes, and each such Participating Broker-Dealer, their counsel and the managing
underwriters, if any, promptly (but in any event within two Business Days), and
confirm such notice in writing, (i) when a Prospectus or any Prospectus
supplement or post-effective amendment has been filed, and, with respect to a
Registration Statement or any post-effective amendment, when the same has become
effective (including in such notice a written statement that any Holder may,
upon request, obtain, without charge, one conformed copy of such Registration
Statement or post-effective amendment including financial statements and
schedules, documents incorporated or deemed to be incorporated by reference and
exhibits), (ii) of the issuance by the Commission of any stop order suspending
the effectiveness of a Registration Statement or of any order preventing or
suspending the use of any preliminary prospectus or the initiation of any
proceedings for that purpose, (iii) if at any time when a prospectus is required
by the Securities Act to be delivered in connection with sales of the
Registrable Notes the representations and warranties of any Issuer contained in
any agreement (including any underwriting agreement contemplated by Section 5(n)
hereof) cease to be true and correct in any material respect, (iv) of the
receipt by any Issuer of any notification with respect to the suspension of the
qualification or exemption from qualification of a Registration Statement or any
of the Registrable Notes or the Exchange Notes to be sold by any Participating
Broker-Dealer for offer or sale in any jurisdiction, or the initiation or
threatening


<PAGE>

                                        -14-

of any proceeding for such purpose, (v) of the happening of any event, the
existence of any condition or any information becoming known that makes any
statement made in such Registration Statement or related Prospectus or any
document incorporated or deemed to be incorporated therein by reference untrue
in any material respect or that requires the making of any changes in, or
amendments or supplements to, such Registration Statement, Prospectus or
documents so that, in the case of the Registration Statement, it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein
not misleading, and that in the case of the Prospectus, it will not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading, and (vi) of the
Issuers' reasonable determination that a post-effective amendment to a
Registration Statement would be appropriate.

                  (d) If (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is required to be delivered under the Securities Act by
any Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period, use its best efforts to prevent the issuance of any order
suspending the effectiveness of a Registration Statement or of any order
preventing or suspending the use of a Prospectus or suspending the qualification
(or exemption from qualification) of any of the Registrable Notes or the
Exchange Notes to be sold by any Participating Broker-Dealer, for sale in any
jurisdiction, and, if any such order is issued, to use its best efforts to
obtain the withdrawal of any such order at the earliest possible date.

                  (e) If a Shelf Registration is filed pursuant to Section 3 and
if requested by the managing underwriters, if any, or the Holders of a majority
in aggregate principal amount of the Registrable Notes being sold in connection
with an underwritten offering, (i) as promptly as practicable incorporate in a
prospectus supplement or post-effective amendment such information or revisions
to information therein relating to such underwriters or selling Holders as the
managing underwriters, if any, or such Holders or their counsel reasonably
request to be included or made therein, (ii) make all required filings of such
prospectus supplement or such post-effective amendment as soon as practicable
after the Issuers have received notification of the matters to be incorporated
in such prospectus supplement or post-effective amendment and (iii) supplement
or make amendments to such Registration Statement to the extent required by law.

                  (f) If (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is


<PAGE>

                                        -15-

required to be delivered under the Securities Act by any Participating
Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period,
furnish to each selling Holder of Registrable Notes and to each such
Participating Broker-Dealer who so requests and to counsel and each managing
underwriter, if any, without charge, one conformed copy of the Registration
Statement or Registration Statements and each post-effective amendment thereto,
including financial statements and schedules, and, if requested, all documents
incorporated or deemed to be incorporated therein by reference and all exhibits.

                  (g) If (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is required to be delivered under the Securities Act by
any Participating Broker-Dealer, deliver to each selling Holder of Registrable
Notes or each such Participating Broker-Dealer, as the case may be, their
respective counsel, and the underwriters, if any, without charge, as many copies
of the Prospectus or Prospectuses (including each form of preliminary
prospectus) and each amendment or supplement thereto and, if requested, any
documents incorporated by reference therein as such Persons may reasonably
request; and, subject to the last paragraph of this Section 5, the Issuers
hereby consent to the use of such Prospectus and each amendment or supplement
thereto by each of the selling Holders of Registrable Notes and each
Participating Broker-Dealer, and the underwriters or agents, if any, and dealers
(if any), in connection with the offering and sale of the Registrable Notes
covered by, or the sale by Participating Broker-Dealers of the Exchange Notes
pursuant to, such Prospectus and any amendment or supplement thereto.

                  (h) Prior to any public offering of Registrable Notes or any
delivery of a Prospectus contained in the Exchange Registration Statement by any
Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period, use its best efforts to register or qualify, and cooperate
with the selling Holders of Registrable Notes and each such Participating
Broker-Dealer, the underwriters, if any, and their respective counsel in
connection with the registration or qualification (or exemption from such
registration or qualification) of such Registrable Notes or Exchange Notes, as
the case may be, for offer and sale under the securities or Blue Sky laws of
such jurisdictions within the United States as any selling Holder, Participating
Broker-Dealer, or the managing underwriter or underwriters, if any, reasonably
request in writing; PROVIDED that where Exchange Notes held by Participating
Broker-Dealers or Registrable Notes are offered pursuant to an underwritten
offering, counsel to the underwriters shall, at the cost and expense of the
Issuers in an amount not to exceed $20,000, perform the Blue Sky investigations
and file registrations and qualifications required to be filed pursuant to this
Section 5(h); keep each such registration or qualification (or exemption
therefrom) effective during the period such Registration Statement is required
to be kept effective and do any and all other acts or things reasonably
necessary or advisable to


<PAGE>

                                        -16-

enable the disposition in such jurisdictions of the Exchange Notes by
Participating Broker-Dealers or the Registrable Notes covered by the applicable
Registration Statement; PROVIDED that no Issuer shall be required to (A) qualify
generally to do business or as a dealer in securities in any jurisdiction where
it is not then so qualified, (B) take any action that would subject it to
general service of process in any such jurisdiction where it is not then so
subject or (C) subject itself to taxation in excess of a nominal dollar amount
in any such jurisdiction where it is not then so subject.

                  (i) If a Shelf Registration is filed pursuant to Section 3,
cooperate with the selling Holders of Registrable Notes, any Participating
Broker-Dealer and the managing underwriter or underwriters, if any, to
facilitate the timely preparation and delivery of certificates representing

covered by the Registration Statement to be registered with or approved by such
governmental agencies or authorities as may be necessary to enable the seller or
sellers thereof or the underwriters, if any, to consummate the disposition of
such Registrable Notes, in which case the Issuers will cooperate in all
reasonable respects with the filing of such Registration Statement and the
granting of such approvals.

                  (k) If (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is required to be delivered under the Securities Act by
any Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period, upon the occurrence of any event contemplated by paragraph
5(c)(v) or 5(c)(vi) hereof, as promptly as practicable prepare and (subject to
Section 5(a) hereof) file with the Commission, at the Issuers' sole expense, a
supplement or post-effective amendment to the Registration Statement or a
supplement to the related Prospectus or any document incorporated or deemed to
be incorporated therein by reference, or file any other required document so
that, as thereafter delivered to the purchasers of the Registrable Notes being
sold thereunder or to the purchasers of the Exchange Notes to whom such
Prospectus will be delivered by a Participating Broker-Dealer, any such
Prospectus will not contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.


<PAGE>

                                        -17-

                  (l) Prior to the effective date of the first Registration
Statement relating to the Registrable Notes, (i) provide the Trustee with
printed certificates for the Registrable Notes or the Exchange Notes, as the

and (ii) provide a CUSIP number for the Registrable Notes or the Exchange Notes,
as the case may be.

                  (m) In connection with an underwritten offering of Registrable
Notes pursuant to a Shelf Registration, enter into an underwriting agreement as
is customary in underwritten offerings of debt securities similar to the Notes
and take all such other actions as are reasonably requested by the managing
underwriter or underwriters in order to expedite or facilitate the registration
or the disposition of such Registrable Notes and, in such connection, (i) make
such representations and warranties to the underwriters, with respect to the
business of the Issuers and their subsidiaries and the Registration Statement,
Prospectus and documents, if any, incorporated or deemed to be incorporated by
reference therein, in each case, as are customarily made by issuers to
underwriters in underwritten offerings of debt securities similar to the Notes,
and confirm the same in writing if and when requested; (ii) obtain the opinion
of counsel to the Issuers and updates thereof in form and substance reasonably
satisfactory to the managing underwriter or underwriters, addressed to the
underwriters covering the matters customarily covered in opinions requested in
underwritten offerings of debt securities similar to the Notes and such other
matters as may be reasonably requested by managing underwriters; (iii) obtain
"cold comfort" letters and updates thereof in form and substance reasonably
satisfactory to the managing underwriter or underwriters from the independent
certified public accountants of the Issuers (and, if necessary, any other
independent certified public accountants of any subsidiary of any Issuer or of
any business acquired by any Issuer for which financial statements and financial
data are, or are required to be, included in the Registration Statement),
addressed to each of the underwriters, such letters to be in customary form and
covering matters of the type customarily covered in "cold comfort" letters in
connection with underwritten offerings of debt securities similar to the Notes
and such other matters as reasonably requested by the managing underwriter or
underwriters; and (iv) if an underwriting agreement is entered into, the same
shall contain indemnification provisions and procedures no less favorable than
those set forth in Section 7 hereof (or such other provisions and procedures
acceptable to Holders of a majority in aggregate principal amount of Registrable
Notes covered by such Registration Statement and the managing underwriter or
underwriters or agents) with respect to all parties to be indemnified pursuant
to said Section. The above shall be done at each closing under such underwriting
agreement, or as and to the extent required thereunder.

                  (n) If (1) a Shelf Registration is filed pursuant to Section
3, or (2) a Prospectus contained in an Exchange Registration Statement filed
pursuant to Section 2 is


<PAGE>

                                        -18-

required to be delivered under the Securities Act by any Participating
Broker-Dealer who seeks to sell Exchange Notes during the Applicable Period,
make available for inspection by any selling Holder of such Registrable Notes
being sold, and each Participating Broker-Dealer, any underwriter participating
in any such disposition of Registrable Notes, if any, and any attorney,
accountant or other agent retained by any such selling Holder, each
Participating Broker-Dealer, as the case may be, or underwriter (collectively,
the "INSPECTORS"), at the offices where normally kept, during reasonable
business hours, all financial and other records, pertinent corporate documents
and properties of each Issuer and its subsidiaries (collectively, the "RECORDS")
as shall be reasonably necessary to enable them to exercise any applicable due
diligence responsibilities, and cause the officers, directors and employees of
each Issuer and its subsidiaries to supply all relevant information reasonably
requested by any such Inspector in connection with such Registration Statement.
Records which an Issuer determines, in good faith, to be confidential and any
Records which it notifies the Inspectors are confidential shall not be disclosed
by the Inspectors unless (i) the disclosure of such Records is necessary to
avoid or correct a material misstatement or omission in such Registration
Statement, (ii) the release of such Records is ordered pursuant to a subpoena or
other order from a court of competent jurisdiction, (iii) the information in
such Records has been made generally available to the public other than as a
result of a disclosure or failure to safeguard by such Inspector or (iv)
disclosure of such information is, in the opinion of counsel for any Inspector,
necessary or advisable in connection with any action, claim, suit or proceeding,
directly or indirectly, involving or potentially involving such Inspector and
arising out of, based upon, related to, or involving this Agreement, or any
transactions contemplated hereby or arising hereunder. Each selling Holder of
such Registrable Notes and each Participating Broker-Dealer will be required to
agree in writing that information obtained by it as a result of such inspections
shall be deemed confidential and shall not be used by it as the basis for any
market transactions in the securities of any Issuer unless and until such is
made generally available to the public. Each Inspector, each selling Holder of
such Registrable Notes and each Participating Broker-Dealer will be required to
further agree in writing that it will, upon learning that disclosure of such
Records is sought in a court of competent jurisdiction pursuant to clauses (ii)
or (iv) of the previous sentence or otherwise, promptly give notice to the
Issuers and allow the Issuers at their expense to undertake appropriate action
to obtain a protective order or otherwise prevent disclosure of the Records
deemed confidential.

                  (o) Provide an indenture trustee for the Registrable Notes or
the Exchange Notes, as the case may be, and cause the Indenture or the trust
indenture provided for in Section 2(a), as the case may be, to be qualified
under the TIA not later than the effective date of the Exchange Offer or the
first Registration Statement relating to the Registrable Notes; and in
connection therewith, cooperate with the trustee under any such indenture and
the Holders of the Registrable Notes, to effect such changes to such indenture
as may be required


<PAGE>

                                        -19-

for such indenture to be so qualified in accordance with the terms of the TIA;
and execute, and use its best efforts to cause such trustee to execute, all
documents as may be required to effect such changes, and all other forms and
documents required to be filed with the Commission to enable such indenture to
be so qualified in a timely manner.

                  (p) Comply with all applicable rules and regulations of the
Commission and make generally available to its securityholders earning
statements satisfying the provisions of Section 11(a) of the Securities Act and
Rule 158 thereunder (or any similar rule promulgated under the Securities Act)
no later than 45 days after the end of any 12-month period (or 90 days after the
end of any 12-month period if such period is a fiscal year) (i) commencing at
the end of any fiscal quarter in which Registrable Notes are sold to
underwriters in a firm commitment or best efforts underwritten offering and (ii)
if not sold to underwriters in such an offering, commencing on the first day of
the first fiscal quarter of the Company after the effective date of a
Registration Statement, which statements shall cover said 12-month periods.

                  (q) If requested by the Trustee, upon consummation of the
Exchange Offer or a Private Exchange, obtain an opinion of counsel to the
Issuers, in a form customary for underwritten transactions, addressed to the
Trustee for the benefit of all Holders of Registrable Notes participating in the
Exchange Offer or the Private Exchange, as the case may be, that the Exchange
Notes or the Private Exchange Notes, as the case may be, and the related
indenture constitute legally valid and binding obligations of the Issuers,
enforceable against the Company in accordance with their respective terms.

                  (r) If the Exchange Offer or a Private Exchange is to be
consummated, upon delivery of the Registrable Notes by Holders to the Issuers
(or to such other Person as directed by the Company) in exchange for the
Exchange Notes or the Private Exchange Notes, as the case may be, the Issuers
shall mark, or caused to be marked, on such Registrable Notes that such
Registrable Notes are being cancelled in exchange for the Exchange Notes or the
Private Exchange Notes, as the case may be; in no event shall such Registrable
Notes be marked as paid or otherwise satisfied.

                  (s) Cooperate with each seller of Registrable Notes covered by
any Registration Statement and each underwriter, if any, participating in the
disposition of such Registrable Notes and their respective counsel in connection
with any filings required to be made with the NASD.


<PAGE>

                                        -20-

                  (t) Use its best efforts to take all other steps reasonably
necessary to effect the registration of the Registrable Notes covered by a
Registration Statement contemplated hereby.

                  The Issuers may require each seller of Registrable Notes as to
which any registration is being effected to furnish to the Issuers such
information regarding such seller and the distribution of such Registrable Notes
as the Issuers may, from time to time, reasonably request. The Issuers may
exclude from such registration the Registrable Notes of any seller who fails to
furnish such information within a reasonable time after receiving such request.
Each seller as to which any Shelf Registration Statement is being effected
agrees to furnish promptly to the Issuers all information required to be
disclosed in order to make the information previously furnished to the Issuers
by such seller not materially misleading.

                  Each Holder of Registrable Notes and each Participating
Broker-Dealer agrees by acquisition of such Registrable Notes or Exchange Notes
to be sold by such Participating Broker-Dealer, as the case may be, that, upon
receipt of any notice from the Issuers of the happening of any event of the kind
described in Section 5(c)(ii), 5(c)(iv), 5(c)(v), or 5(c)(vi), such Holder will
forthwith discontinue disposition of such Registrable Notes covered by such
Registration Statement or Prospectus or Exchange Notes to be sold by such Holder
or Participating Broker-Dealer, as the case may be, and, in each case,
dissemination of such Prospectus until such Holder's or Participating
Broker-Dealer's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 5(k), or until it is advised in writing (the "ADVICE")
by the Company that the use of the applicable Prospectus may be resumed, and has
received copies of any amendments or supplements thereto. In the event the
Issuers shall give any such notice, the Applicable Period shall be extended by
the number of days during such periods from and including the date of the giving
of such notice to and including the date when each seller of Registrable Notes
covered by such Registration Statement or Exchange Notes to be sold by such
Participating Broker-Dealer, as the case may be, shall have received (x) the
copies of the supplemented or amended Prospectus contemplated by Section 5(k) or
(y) the Advice.

6.       REGISTRATION EXPENSES

                  All fees and expenses incident to the performance of or
compliance with this Agreement by the Issuers shall be borne by the Issuers
whether or not the Exchange Offer or a Shelf Registration is filed or becomes
effective, including, without limitation, (i) all registration and filing fees
(including, without limitation, (A) fees with respect to filings required to be
made with the NASD in connection with an underwritten offering and (B) fees and

Notes to be sold by a Participating Broker-Dealer during the Applicable
Period)), (ii) printing expenses, including, without limitation, expenses of

amount of the Registrable Notes included in any Registration Statement or by any
Participating Broker-Dealer, as the case may be, (iii) reasonable messenger,
telephone and delivery expenses incurred in connection with the Exchange
Registration Statement and any Shelf Registration, (iv) reasonable fees and
disbursements of counsel for the Issuers, and (exclusive of any counsel retained
pursuant to Section 7 hereof) fees and disbursements of special counsel for the

shall be paid by Holders of such Registrable Notes) and (xiii) the expenses
relating to printing, word processing and distributing all Registration
Statements, underwriting agreements, securities sales agreements, indentures and
any other documents necessary in order to comply with this Agreement.

7.       INDEMNIFICATION

                  (a) Each of the Issuers jointly and severally agrees to
indemnify and hold harmless each Holder of Registrable Notes and each
Participating Broker-Dealer, the officers, directors, employees and agents of
each such Person, and each Person, if any, who controls any such Person within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act (each, a "PARTICIPANT"), from and against any and all losses,
claims, damages


<PAGE>

                                        -22-

and liabilities (including, without limitation, the reasonable legal fees and
other reasonable expenses actually incurred in connection with any suit, action
or proceeding or any claim asserted) caused by, arising out of or based upon any
untrue statement or alleged untrue statement of a material fact contained in any
Registration Statement or Prospectus (as amended or supplemented if the Issuers
shall have furnished any amendments or supplements thereto) or caused by,
arising out of or based upon any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, except insofar as such losses, claims, damages or liabilities are
caused by any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with information relating to
any Participant furnished to the Issuers in writing by or on behalf of such
Participant expressly for use therein; PROVIDED, HOWEVER, that the Issuers shall
not be liable if such untrue statement or omission or alleged untrue statement
or omission was contained or made in any preliminary prospectus and corrected in
the Prospectus or any amendment or supplement thereto and the Prospectus does
not contain any other untrue statement or omission or alleged untrue statement
or omission of a material fact that was the subject matter of the related
proceeding and any such loss, liability, claim, damage or expense suffered or
incurred by the Participants resulted from any action, claim or suit by any
Person who purchased Registrable Notes or Exchange Notes which are the subject
thereof from such Participant and it is established in the related proceeding
that such Participant failed to deliver or provide a copy of the Prospectus (as
amended or supplemented) to such Person with or prior to the confirmation of the
sale of such Registrable Notes or Exchange Notes sold to such Person if required
by applicable law, unless such failure to deliver or provide a copy of the
Prospectus (as amended or supplemented) was a result of noncompliance by the
Issuers with Section 5 of this Agreement.

                  (b) Each Participant, by virtue of its beneficial ownership of
Notes, agrees, severally and not jointly, to indemnify and hold harmless each
Issuer, its directors, managers, officers (including each officer of the Issuers
who signed the Registration Statement), employee and agents and each Person who
controls each Issuer within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act to the same extent as the foregoing indemnity
from the Issuers to each Participant, but only with reference to information
relating to such Participant furnished to the Issuers in writing by or on behalf
of such Participant expressly for use in any Registration Statement or
Prospectus, any amendment or supplement thereto, or any preliminary prospectus.
The liability of any Participant under this paragraph shall in no event exceed
the proceeds received by such Participant from sales of Registrable Notes or
Exchange Notes giving rise to such obligations.


<PAGE>

                                        -23-

                  (c) If any suit, action, proceeding (including any
governmental or regulatory investigation), claim or demand shall be brought or
asserted against any Person in respect of which indemnity may be sought pursuant
to either of the two preceding paragraphs, such Person (the "INDEMNIFIED
PERSON") shall promptly notify the Person against whom such indemnity may be
sought (the "INDEMNIFYING PERSON") in writing, and the Indemnifying Person, upon
request of the Indemnified Person, shall retain counsel reasonably satisfactory
to the Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may reasonably designate in such proceeding and shall pay
the reasonable fees and expenses actually incurred by such counsel related to
such proceeding; PROVIDED, HOWEVER, that the failure to so notify the
Indemnifying Person shall not relieve it of any obligation or liability which it
may have hereunder or otherwise, except to the extent that it is materially
prejudiced by such failure. In any such proceeding, any Indemnified Person shall
have the right to retain its own counsel, but the fees and expenses of such
counsel shall be at the expense of such Indemnified Person unless (i) the
Indemnifying Person and the Indemnified Person shall have mutually agreed in
writing to the contrary, (ii) the Indemnifying Person has failed within a
reasonable time to retain counsel reasonably satisfactory to the Indemnified
Person or (iii) the named parties in any such proceeding (including any
impleaded parties) include both the Indemnifying Person and the Indemnified
Person and counsel for the Indemnified Person shall have reasonably concluded
that there may be one or more legal defenses available to it and/or other
Indemnified Persons such Indemnifying Person. It is understood that, unless
there is a conflict among Indemnified Persons, the Indemnifying Person shall
not, in connection with any proceeding or related proceeding in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all Indemnified Persons, and that all
such fees and expenses shall be reimbursed as they are incurred. Any such
separate firm for the Participants and such control Persons of Participants
shall be designated in writing by Participants who sold a majority in interest
of Registrable Notes sold by all such Participants and any such separate firm
for each Issuer, its directors, managers, officers and such control Persons of
each Issuer shall be designated in writing by the Company. The Indemnifying
Person shall not be liable for any settlement of any proceeding effected without
its written consent, but if settled with such consent or if there is a final
non-appealable judgment for the plaintiff, the Indemnifying Person agrees to
indemnify any Indemnified Person from and against any loss or liability by
reason of such settlement or judgment. Notwithstanding the foregoing sentence,
if at any time an Indemnified Person shall have requested an Indemnifying Person
to reimburse the Indemnified Person for reasonable fees and expenses actually
incurred by counsel as contemplated by the third sentence of this paragraph, the
Indemnifying Person agrees that it shall be liable for any settlement of any
proceeding effected without its consent if (i) such settlement is entered into
more than 30 days after receipt by such Indemnifying Person of the aforesaid
request (ii) such Indemnifying Person shall have received notice of a proposed


<PAGE>

                                        -24-

settlement at least 2 business days prior to such settlement being entered into,
and (iii) such Indemnifying Person shall not have reimbursed the Indemnified
Person in accordance with such request prior to the date of such settlement;
PROVIDED, HOWEVER, that the Indemnifying Person shall not be liable for any
settlement effected without its consent pursuant to this sentence if the
Indemnifying Person is contesting, in good faith, the request for reimbursement.
No Indemnifying Person shall, without the prior written consent of the
Indemnified Person, effect any settlement of any pending or threatened
proceeding in respect of which any Indemnified Person is or could have been a
party and indemnity could have been sought hereunder by such Indemnified Person,
unless such settlement (A) includes an unconditional release of such Indemnified
Person, in form and substance satisfactory to such Indemnified Person, from all
liability on claims that are the subject matter of such proceeding and (B) does
not include any statement as to an admission of fault, culpability or failure to
act by or on behalf of an Indemnified Person.

                  (d) If the indemnification provided for in the first and
second paragraphs of this Section 7 is unavailable to, or insufficient to hold
harmless, an Indemnified Person in respect of any losses, claims, damages or
liabilities referred to therein, then each Indemnifying Person under such
paragraphs, in lieu of indemnifying such Indemnified Person thereunder and in
order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect
the relative fault of the Indemnifying Person or Persons on the one hand and the
Indemnified Person or Persons on the other in connection with the statements or
omissions (or alleged statements or omissions) that resulted in such losses,
claims, damages or liabilities (or actions in respect thereof) as well as any
other relevant equitable considerations. The relative fault of the parties shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Issuers on the one hand
or by the Participants or such other Indemnified Person, as the case may be, on
the other, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission and any other
equitable considerations appropriate under the circumstances.

                  (e) The parties agree that it would not be just and equitable
if contribution pursuant to this Section 7 were determined by PRO RATA
allocation (even if the Participants were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages and liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any reasonable legal or other expenses


<PAGE>

                                        -25-

actually incurred by such Indemnified Person in connection with investigating or
defending any such action or claim. Notwithstanding the provisions of this
Section 7, in no event shall a Participant be required to contribute any amount
in excess of the amount by which proceeds received by such Participant from
sales of Registrable Notes or Exchange Notes, as the case may be, exceeds the
amount of any damages that such Participant has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

                  (f) The indemnity and contribution agreements contained in
this Section 7 will be in addition to any liability which the Indemnifying
Persons may otherwise have to the Indemnified Persons referred to above.

8.       RULES 144 AND 144A

                  Each of the Issuers covenants that it will use its reasonable
best efforts to file the reports, if any, required to be filed by it under the
Securities Act and the Exchange Act and the rules and regulations adopted by the
Commission thereunder in a timely manner and, if at any time it is not required
to file such reports, it will, upon the request of any Holder of Registrable
Notes, make publicly available other information so long as necessary to permit
sales of such Holder's Registrable Notes pursuant to Rule 144 and Rule 144A
under the Securities Act. The Issuers further covenant, for so long as any
Registrable Notes remain outstanding, to make available to any Holder or
beneficial owner of Registrable Notes in connection with any sale thereof and
any prospective purchaser of such Registrable Notes from such Holder or
beneficial owner, the information required by Rule 144A(d)(4) under the
Securities Act in order to permit resales of such Registrable Notes pursuant to
Rule 144A.

9.       UNDERWRITTEN REGISTRATIONS

                  If any of the Registrable Notes covered by any Shelf
Registration are to be sold in an underwritten offering, the investment banker
or investment bankers and manager or managers that will manage the offering will
be selected by the Holders of a majority in aggregate principal amount of such
Registrable Notes included in such offering and must be reasonably acceptable to
the Issuers.

                  No Holder of Registrable Notes may participate in any
underwritten registration hereunder unless such Holder (a) agrees to sell such
Holder's Registrable Notes on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements and (b) completes and executes all questionnaires, powers of


<PAGE>

                                        -26-

attorney, indemnities, underwriting agreements, lock-up letters and other
documents required under the terms of such underwriting arrangements.

10.      MISCELLANEOUS

                  (a) REMEDIES. In the event of a breach by any Issuer of any of
its obligations under this Agreement, each Holder of Registrable Notes and each
Participating Broker-Dealer holding Exchange Notes, in addition to being
entitled to exercise all rights provided herein, in the Indenture or, in the
case of an Initial Purchaser, in the Purchase Agreement, or granted by law,
including recovery of damages, will be entitled to specific performance of its
rights under this Agreement. Each Issuer agrees that monetary damages would not
be adequate compensation for any loss incurred by reason of a breach by it of
any of the provisions of this Agreement and hereby further agrees that, in the
event of any action for specific performance in respect of such breach, it shall
waive the defense that a remedy at law would be adequate.

                  (b) NO INCONSISTENT AGREEMENTS. None of the Issuers has
entered, as of the date hereof, and none of the Issuers shall enter, after the
date of this Agreement, into any agreement with respect to any of its securities
that is inconsistent with the rights granted to the Holders of Registrable Notes
in this Agreement or otherwise conflicts with the provisions hereof. None of the
Issuers has entered and none of the Issuers shall enter into any agreement with
respect to any of its securities which will grant to any Person piggy-back
rights with respect to a Registration Statement.

                  (c) ADJUSTMENTS AFFECTING REGISTRABLE NOTES. None of the
Issuers shall, directly or indirectly, take any action with respect to the
Registrable Notes as a class that would adversely affect the ability of the
Holders of Registrable Notes to include such Registrable Notes in a registration
undertaken pursuant to this Agreement.

                  (d) AMENDMENTS AND WAIVERS. The provisions of this Agreement
may not be amended, modified or supplemented, and waivers or consents to
departures from the provisions hereof may not be given, otherwise than with the
prior written consent of (A) the Holders of not less than a majority in
aggregate principal amount of the then outstanding Registrable Notes and (B) in
circumstances that would adversely affect Participating Broker-Dealers, the
Participating Broker-Dealers holding not less than a majority in aggregate
principal amount of the Exchange Notes held by all Participating Broker-Dealers;
PROVIDED, HOWEVER, that Section 7 and this Section 10(d) may not be amended,
modified or supplemented without the prior written consent of each Holder and
each Participating Broker-Dealer (including any person who was a Holder or
Participating Broker-Dealer of Registrable


<PAGE>

                                        -27-

Notes or Exchange Notes, as the case may be, disposed of pursuant to any
Registration Statement). Notwithstanding the foregoing, a waiver or consent to
depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of Holders of Registrable Notes whose securities are
being tendered pursuant to the Exchange Offer or sold pursuant to a Registration
Statement and that does not directly or indirectly affect, impair, limit or
compromise the rights of other Holders of Registrable Notes may be given by
Holders of at least a majority in aggregate principal amount of the Registrable
Notes being tendered or being sold by such Holders pursuant to such Registration
Statement.

2.       REGISTRATION RIGHTS.

proposes to file a Registration Statement under the Securities Act with respect
to an offering by the Company for its own account or for the account of any of
its respective securityholders covering the sale of Common Stock (other than (a)
a registration statement on Form S-4 or S-8 or any similar or successor form or
in connection with a registration the primary purpose of which is to register
debt securities (I.E., in connection with a so-called "equity kicker"), or (b) a
registration statement filed in connection with an offer of securities solely to
the Company's existing securityholders) for sale on the same terms and
conditions as the securities of the Company or any other selling securityholder
included therein, then the Company shall give written notice of


<PAGE>

                                      -6-


such proposed filing to the Holders of Registrable Securities as soon as
practicable (but in no event less than 10 Business Days before the
anticipated filing date), and such notice shall offer such Holders the
opportunity to register such number of Registrable Securities as each such
Holder may request (which request shall specify the Registrable Securities
intended to be disposed of by such Holder and the intended method of
distribution thereof) (a "PIGGY-BACK REGISTRATION"). The Company shall use
its commercially reasonable efforts to cause the managing underwriter or
underwriters of such proposed underwritten offering to permit the Registrable
Securities requested to be included in a Piggy-Back Registration to be
included on the same terms and conditions as any similar securities of the
Company or any other securityholder included therein and to permit the sale
or other disposition of such Registrable Securities in accordance with the
intended method of distribution thereof. Any Holder shall have the right to
withdraw its request for inclusion of its Registrable Securities in any
Registration Statement pursuant to this Section 2.2 by giving written notice
to the Company of its request to withdraw. The Company may withdraw a
Piggy-Back Registration at any time prior to the time it becomes effective;
PROVIDED that the Company shall give prompt notice thereof to participating
Holders. The Company will pay all Registration Expenses in connection with
each registration of Registrable Securities requested pursuant to this
Section 2.1, and each Holder shall pay all underwriting discounts and
commissions and transfer taxes, if any, relating to the sale or disposition
of such Holder's Registrable Securities pursuant to a registration statement
effected pursuant to this Section 2.1.

                  No failure to effect a registration under this Section 2.1 and
to complete the sale of Registrable Securities in connection therewith shall
relieve the Company of any other obligation under this Agreement.

                  2.2. REDUCTION OF PIGGY-BACK REGISTRATION. (a) If the lead
managing underwriter of any underwritten offering described in Section 2.1 has
informed, in writing, the Holders of the Registrable Securities requesting
inclusion in such offering that it is its view that the total number of
securities which the Company, the Holders and any other Persons desiring to
participate in such registration intend to include in such offering exceeds the
number which can be sold in an orderly manner within a price range acceptable to
the Company and without adversely affecting the marketability of the offering,
then the securities the Company proposes to sell shall first be included in such
offering, and then the number of Registrable Securities to be offered for the
account of such Holders and the number of such securities to be offered for the
account of all such other Persons (other than the Company) participating in such
registration shall be reduced or limited PRO RATA in proportion to the
respective number of securities owned by the participating Persons to the extent
necessary to reduce the total number of securities requested to be included in
such offering to the number of securities, if any, recommended by such lead

                  (b) If the lead managing underwriter of any underwritten
offering described in Section 2.1 notifies the Holders requesting inclusion of
Registrable Securities in such offering that the kind of securities that such
Holders, the Company and any other Persons desiring to participate in such
registration intend to include in such offering is such as to materially and
adversely affect the success of such offering, (x) the Registrable Securities to
be included in such offering shall be reduced as described in clause (a) above
or (y) if a reduction in the Registrable Securities pursuant to clause (a) above
would, in the judgment of the lead managing underwriter, be insufficient to
substantially eliminate the adverse effect that inclusion of the Registrable
Securities requested to be included would have on such offering, such
Registrable Securities will be excluded from such offering.

                  (c) If, as a result of the proration provisions of this
Section 2.2, any Holder shall not be entitled to include all Registrable
Securities in a Piggy-Back Registration that such Holder has requested to be
included, such Holder may elect to withdraw his request to include Registrable
Securities in such registration (a "WITHDRAWAL ELECTION"); PROVIDED that a
Withdrawal Election shall be irrevocable and, after making a Withdrawal
Election, a Holder shall no longer have any right to include Registrable
Securities in the registration as to which such Withdrawal Election was made.

3.       TRANSFERS.

                  3.1. GENERALLY. All Subject Equity at any time and from time
to time outstanding shall be held subject to the conditions and restrictions set
forth in this Section 3. All shares of Capital Stock now or hereafter held by
the Investor shall be held subject to the conditions and restrictions set forth
in this Section 3. Each Holder of Subject Equity and the Investor by executing
this Agreement or by accepting a certificate representing Capital Stock or other
indicia of ownership therefor from the Company agree with the Company and with
each other Stockholder to such conditions and restrictions.

                  3.2. TAG-ALONG RIGHTS. (a) Prior to an Initial Public Equity
Offering, each of the Holders of Subject Equity shall have the right (the
"TAG-ALONG RIGHT") to require the Proposed Purchaser (as defined below) to
purchase from each of them all (subject to (c) below) Subject Equity owned by
such Holder in the event of any proposed direct or indirect sale or other
disposition (collectively, a "TRANSFER") of Capital Stock of the Company or
Capital Stock of the Investor (whether now or hereafter issued) to any Person or
Persons (such other Person or Persons being hereinafter referred to as the
"PROPOSED PURCHASER") by the Investor or any of its Affiliates in any
transaction or series of related transactions of the Company's Common Stock
representing 25% or more of the aggregate number of shares of common stock of
the Company owned by the Investor on the date hereof or more than 25% of the
common stock of the Investor (other than sales in a bona fide public offering
pursuant to an effective registration statement under the Securities Act, sales
to the public pursuant to the

<PAGE>

                                      -8-


provisions of Rule 144 (or any similar rule or rules then in effect) under
the Securities Act, transfers to the Investor or one or more of its
stockholders pursuant to the right of first refusal contained in Section
3.1(b) of the Stockholders Agreement and transfers to Affiliates and certain
other transfers permitted by Section 3.1(d) of the Stockholders Agreement).
Any Investor proposing a transfer which triggers the rights under this
Section 3.2(a) shall notify, or cause to be notified, each Holder of Subject
Equity in writing (a "TRANSFER NOTICE") of each such proposed Transfer at
least 10 Business Days prior to the date thereof. Such notice shall set
forth: (a) the name of the Proposed Purchaser and the number of shares of
Common Stock and other securities, if any, proposed to be transferred, (b)
the proposed amount of consideration and terms and conditions of payment
offered by such Proposed Purchaser (if the proposed consideration is not
cash, the Transfer Notice shall describe the terms of the proposed
consideration) and (c) that either the Proposed Purchaser has been informed
of the "Tag-Along Right" and has agreed to purchase Subject Equity in
accordance with the terms hereof or that the Investor or any of its
Affiliates will make such purchase. The Tag-Along Right may be exercised by
any Holder of Subject Equity by delivery of a written notice to the Investor
who delivered the Transfer Notice ("TAG-ALONG NOTICE"), within 5 Business
Days of receipt of the Transfer Notice, indicating its election to exercise
the Tag-Along Right (the "PARTICIPATING HOLDERS"). The Tag-Along Notice shall
state the amounts of Subject Equity that such Holder proposes to include in
such Transfer to the Proposed Purchaser. Failure by any Holder to provide a
Tag-Along Notice within the 5 Business Day notice period shall be deemed to
constitute an election by such Holder not to exercise its Tag-Along Right.
The closing with respect to any sale to a Proposed Purchaser pursuant to this
Section shall be held at the time and place specified in the Transfer Notice.
Consummation of the sale of Common Stock by the Investor or any of its
Affiliates to a Proposed Purchaser shall be conditioned upon consummation of
the sale by each Participating Holder to such Proposed Purchaser (or the
Investor) of the Subject Equity entitled to be transferred as described in
(c) below, if any. Additionally:

                  (b) In the event that the Proposed Purchaser does not purchase
Subject Equity entitled to be transferred as described in (c) below, on the same
terms and conditions as purchased from the Investor or any of its Affiliates,
then the Investor or to its Affiliates shall purchase such Subject Equity if the
Transfer occurs.

                  (c) Each Holder shall have the right to require the Proposed
Purchaser to purchase from such Holder that percentage of the aggregate number
of shares of Common Stock desired to be transferred by such Holder equal to a
fraction, expressed as a percentage, equal to (i) if the transaction is a sale
of Capital Stock of the Company, the percentage of the Investor's Capital Stock
of the Company being sold by the Investor, or (ii) if the transaction is a sale
of Capital Stock of the Investor, the percentage of the Investor's Capital Stock
being sold by the parties to the Stockholders Agreement.

                                      -9-


                  (d) Any Subject Equity purchased from the Participating
Holders pursuant to this Section 3.2 shall be paid for in the same type of
consideration and at the same price per share of Common Stock and upon the same
terms and conditions of such proposed Transfer of Common Stock by the Investor
and/or any of its Affiliates. The price per Warrant to be paid by the Proposed
Purchaser shall be reduced by the exercise price of such Warrant per share. If
the Subject Equity to be purchased includes securities or property other than
Common Stock, the price to be paid for such securities or property shall be the
same price per share or other denomination paid by the Proposed Purchaser for
like securities purchased from the Investor or any of its Affiliates. If the
securities being purchased in the transaction consist of Capital Stock of the
Investor, the price paid to the Participating Holders shall be appropriately
adjusted to reflect the Investor's relative ownership of the Company and the
price paid to the Investor's Affiliates in the transaction. The Investor shall
arrange for payment directly by the Proposed Purchaser to each Participating
Holder, upon delivery of the certificate or certificates representing the
Warrants and/or Registrable Securities duly endorsed for transfer, together with
such other documents as the Proposed Purchaser may reasonably request.

                  (e) If the sale of Common Stock by the Investor or its
Affiliates and the sale of the Subject Equity entitled to be transferred as
provided above have not been completed in accordance with the terms of the
Proposed Purchaser's offer, all certificates representing such Subject Equity
shall be returned to the Participating Holders, and all the restrictions on
Transfer contained in this Agreement with respect to Common Stock owned by the
Investor and its Affiliates shall remain in effect.

                  (f) If the Investor proposing the Transfer intends to Transfer
a strip of two or more classes of shares and any Participating Holder holds all
such classes, such Participating Holder may only participate in such Transfer if
such Participating Holder participates with respect to all such classes of
shares.

                  (g) Each Participating Holder shall be required to bear its
PRO RATA share (based upon the number of shares sold) of the expenses incurred
by the transferring stockholders in connection with such transaction to the
extent such costs are incurred for the benefit of all such stockholders and are
not otherwise paid by the Company or the Proposed Purchaser.

                  3.3. DRAG-ALONG RIGHTS. If at any time prior to an Initial
Public Equity Offering, (i) the Investor and/or any of its Affiliates determines
to sell all or substantially all of the Capital Stock of the Company owned by it
to a Person other than the Investor or an Affiliate of the Investor, or (ii) the
stockholders of the Investor determine to sell all or substantially all of the
Capital Stock of the Investor to a Person other than the Investor or an
Affiliate of the Investor, then the Investor (whether directly or through an
Affiliate) shall have the right to require the Holders of Subject Equity to sell
such Subject Equity to such transferee; PROVIDED


<PAGE>

                                      -10-


that the consideration to be received by the Holders of Subject Equity shall
be the same type of consideration received by the Investor and its
Affiliates. Any Warrants and/or Registrable Securities purchased from the
Holders thereof pursuant to this Section 3.3 shall be paid for at the same
price per share of Common Stock and upon the same terms and conditions of
such proposed transfer of Common Stock or other securities by the Investor
and its Affiliates. The price per Warrant to be paid by the Proposed
Purchaser shall be reduced by the exercise price of such Warrant per share.
If the Subject Equity to be purchased includes securities other than Common
Stock, the price to be paid for such securities shall be the same price per
share or other denomination paid by the Proposed Purchaser for like
securities purchased from the Investor and its Affiliates or, if like
securities are not purchased from the Investor and its Affiliates, the Fair
Market Value of such securities.

4.       REGISTRATION PROCEDURES.

         managing underwriters, if any, copies of all such documents proposed to

         Holders, and such underwriters, if any, and cause the officers and
         directors of the Company, counsel to the Company and independent
         certified public accountants to the Company to respond to such
         reasonable inquiries as shall be necessary, in the opinion of counsel
         to such underwriters, to conduct a reasonable investigation within the

         and information gathering shall be coordinated on behalf of the Initial
         Purchasers by CIBC;

                  (b) Prepare and file with the SEC such amendments, including
         post-effective amendments, to each Registration Statement as may be
         necessary to keep such Registration Statement continuously effective
         for the applicable time period required hereunder; cause the related
         Prospectus to be supplemented by any required Prospectus supplement,
         and as so supplemented to be filed pursuant to Rule 424 under the
         Securities Act; and comply with the provisions of the Securities Act
         and the Exchange Act with respect to the disposition of all securities
         covered by such Registration Statement during such period in accordance
         with the intended methods of disposition by the sellers thereof set
         forth in such Registration Statement as so amended or in such

         Prospectus or any Prospectus supplement or post-effective amendment is
         proposed to be filed, and (B) with respect to a Registration Statement
         or any post-effective amendment, when the same has become effective,

         governmental authority for amendments or supplements to a Registration
         Statement or related Prospectus or for additional information, (iii) of
         the issuance by the SEC, any state securities commission, any other
         governmental agency or any court of any stop order, order or injunction
         suspending or enjoining the use of a Prospectus or the effectiveness of
         a Registration Statement or the initiation of any proceedings for that
         purpose, (iv) of the receipt by the Company of any notification with
         respect to the suspension of the qualification or exemption from
         qualification of any of the Registrable Securities for sale in any
         jurisdiction, or the initiation or threatening of any proceeding for
         such purpose, and (v) of the happening of any event or information
         becoming known that makes any statement made in a Registration
         Statement or related Prospectus or any document incorporated or deemed
         to be incorporated therein by reference untrue in any material respect
         or that requires the making of any changes in such Registration
         Statement, Prospectus or documents so that it will not contain any
         untrue statement of a material fact or omit to state any material fact
         required to be stated therein or necessary to make the statements
         therein, not misleading, and that in the case of a Prospectus, it will

         any material fact required to be stated therein or necessary to make
         the statements therein, in light of the circumstances under which they
         were made, not misleading;

                  (d) Use its reasonable best efforts to avoid the issuance of
         or, if issued, obtain the withdrawal of any order enjoining or
         suspending the use of a Prospectus or the effectiveness of a
         Registration Statement or the lifting of any suspension of the
         qualification (or exemption from qualification) of any of the
         Registrable Securities for sale in any jurisdiction, at the earliest
         practicable moment;

                  (e) If requested by the managing underwriters, if any, (i)

         required filings of such Prospectus supplement or such post-effective
         amendment under the Securities Act as soon as practicable after the

         such Prospectus supplement or post-effective amendment; PROVIDED,
         HOWEVER, that the Company shall not be required to take any action
         pursuant to this Section 4(e) that would, in the opinion of counsel for
         the Company, violate applicable law;

         previously furnished or incorporated by reference) as soon as
         practicable after the filing of such documents with the SEC;

                  (g) Deliver to each Holder of Registrable Securities to be
         sold pursuant to a Registration Statement, and the underwriters, if

         under the securities or Blue Sky laws of such jurisdictions as any such
         Holder or underwriter reasonably requests in writing; use its
         reasonable best efforts to keep each such registration or qualification
         (or exemption therefrom) effective during the period such Registration
         Statement is required to be kept effective hereunder and do any and all
         other acts or things necessary or advisable to enable the disposition
         in such jurisdictions of the Registrable Securities covered by the
         applicable Registration Statement; PROVIDED, HOWEVER, that the Company
         shall not be required to (i) qualify generally to do business in any
         jurisdiction where it is not then so qualified or (ii) take any action
         which would subject it to general service of process or to taxation in
         any jurisdiction where they are not so subject;

         Registration Statement or a supplement to the related Prospectus or any
         document incorporated or deemed to be incorporated therein by
         reference, and file any other required document so that, as thereafter
         delivered, such Prospectus will not contain an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading;

         Securities and the underwriters, if any, with respect to the business
         of the Company and its subsidiaries (including with respect to
         businesses or assets acquired or to be acquired by any of them), and
         the Registration Statement, Prospectus and documents, if any,
         incorporated or deemed to be incorporated by reference therein, in each
         case, in form, substance and scope as are customarily made by issuers
         to underwriters in underwritten offerings, and confirm the same if and
         when requested; (ii) obtain opinions of counsel to the Company and
         updates thereof (which counsel and opinions (in form, scope and
         substance) shall be reasonably satisfactory to the managing
         underwriters, if any, addressed to each selling Holder of Registrable
         Securities (if so requested by them) and each of the underwriters, if

         for which financial statements and financial data is, or is required to
         be, included in the Registration Statement), addressed (where
         reasonably possible) to each selling Holder of Registrable Securities

         letters to be in customary form and covering matters of the type
         customarily covered in "cold comfort" letters in connection with
         underwritten offerings; (iv) if an underwriting agreement is entered
         into, the same shall contain indemnification provisions and procedures
         no less favorable to the selling Holders and the underwriters, if any,
         than those set forth in Section 5 hereof (or such other provisions and

         other than the Company and its subsidiaries and such source is not
         bound by a confidentiality agreement; and PROVIDED, FURTHER, that the
         foregoing inspection and information gathering shall be coordinated on
         behalf of the Initial Purchasers by CIBC;

         to underwriters in such an offering, commencing on the first day
         of the first fiscal quarter after the effective date of a
         Registration Statement, which statement shall cover said period,
         consistent with the requirements of Rule 158 under the Securities
         Act; and

                  (n) Cooperate with each seller of Registrable Securities
         covered by any Registration Statement and each underwriter, if any,
         participating in the disposition of such Registrable Securities and
         their respective counsel in connection with any filings required to be
         made with the National Association of Securities Dealers, Inc.

                  The Company may require a Holder of Registrable Securities to
be included in a Registration Statement to furnish to the Company such
information regarding (i) the intended method of distribution of such
Registrable Securities, (ii) such Holder and (iii) the Registrable Securities
held by such Holder as is required by law to be disclosed in such Registration
Statement and the Company may exclude from such Registration Statement the
Registrable Securities of any Holder who unreasonably fails to furnish such
information within a reasonable time after receiving such request.

                  If any such Registration Statement refers to any Holder by
name or otherwise as the Holder of any securities of the Company, then such
Holder shall have the right to require (i) the insertion therein of language, in
form and substance reasonably satisfactory to such Holder, to the effect that
the holding by such Holder of such securities is not to be construed as a
recommendation by such Holder of the investment quality of the Company's
securities covered thereby and that such holding does not imply that such Holder
will assist in meeting any future financial requirements of the Company, or (ii)
in the event that such reference to such Holder by name or otherwise is not
required by the Securities Act, the deletion of the reference to such Holder in
any amendment or supplement to the Registration Statement filed or prepared
subsequent to the time that such reference ceases to be required.

                  Each Holder of Registrable Securities agrees by acquisition of
such Registrable Securities that, upon receipt of any notice from the Company of
the happening of any event of the kind described in Section 4(c)(ii), 4(c)(iii),
4(c)(iv) or 4(c)(v) hereof, such Holder will forthwith discontinue disposition
of such Registrable Securities covered by such Registration Statement or
Prospectus until such Holder's receipt of the copies of the supplemented or
amended Prospectus contemplated by Section 4(j) hereof, or until it is advised
in writing (the "ADVICE") by the Company that the use of the applicable
Prospectus may be resumed, and, in either case, has received copies of any
additional or supplemental filings that are incorporated or deemed to be
incorporated by reference in such Prospectus. If the Company shall give any such
notice, the Effectiveness Period shall be extended by the number of days during
such period from and including the date of the giving of such notice to and
including the date when each Holder of Registrable Securities covered by such
Registration Statement shall have

<PAGE>

                                      -16-


received (x) the copies of the supplemented or amended Prospectus
contemplated by Section 4(j) hereof or (y) the Advice, and, in either case,
has received copies of any additional or supplemental filings that are
incorporated or deemed to be incorporated by reference in such Prospectus.

5.       INDEMNIFICATION AND CONTRIBUTION.

                  (a) The Company shall indemnify and hold harmless the Initial
Purchasers, each Holder, each underwriter who participates in an offering of
Registrable Securities, their respective Affiliates, each Person, if any, who
controls any of such parties within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act and each of their respective directors,
officers, employees and agents, as follows:

                    (i) against any and all loss, liability, claim, damage and
         expense whatsoever, joint or several, as incurred, arising out of any
         untrue statement or alleged untrue statement of a material fact
         contained in any Registration Statement (or any amendment thereto),
         covering Registrable Securities, including all documents incorporated
         therein by reference, or the omission or alleged omission therefrom of
         a material fact required to be stated therein or necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading or arising out of any untrue statement or
         alleged untrue statement of a material fact contained in any Prospectus
         (or any amendment or supplement thereto) or the omission or alleged
         omission therefrom of a material fact necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading;

                   (ii) against any and all loss, liability, claim, damage and
         expense whatsoever, joint or several, as incurred, to the extent of the
         aggregate amount paid in settlement of any litigation, or any
         investigation or proceeding by any court or governmental agency or
         body, commenced or threatened, or of any claim whatsoever based upon
         any such untrue statement or omission, or any such alleged untrue
         statement or omission, if such settlement is effected with the prior
         written consent of the Company; and

                  (iii) against any and all expenses whatsoever, as incurred
         (including reasonable fees and disbursements of counsel chosen by
         CIBC), reasonably incurred in investigating, preparing or defending
         against any litigation, or any investigation or proceeding by any court
         or governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission, to the extent that any such
         expense is not paid under subparagraph (i) or (ii) of this Section
         5(a);

<PAGE>

                                      -17-


PROVIDED that this indemnity does not apply to any loss, liability, claim,
damage or expense to the extent arising out of an untrue statement or omission
or alleged untrue statement or omission (i) made in reliance upon and in
conformity with written information furnished to the Company by such Holder or
any underwriter in writing expressly for use in the Registration Statement (or
any amendment thereto) or any Prospectus (or any amendment or supplement
thereto) or (ii) contained in any preliminary prospectus if such Holder or such
underwriter failed to send or deliver a copy of the Prospectus (in the form it
was first provided to such parties for confirmation of sales) to the Person
asserting such losses, claims, damages or liabilities on or prior to the
delivery of written confirmation of any sale of securities covered thereby to
such Person in any case where such delivery is required by the Securities Act
and such Prospectus would have corrected such untrue statement or omission. Any
amounts advanced by the Company to an indemnified party pursuant to this Section
5 as a result of such losses shall be returned to the Company if it shall be
finally determined by such a court in a judgment not subject to appeal or final
review that such indemnified party was not entitled to indemnification by the
Company.

                  (b) By accepting the benefits of this Agreement, each Holder
agrees, severally and not jointly, to indemnify and hold harmless the Company,
each Initial Purchaser, each underwriter who participates in an offering of
Registrable Securities and the other selling Holders and each of their
respective directors, officers (including each officer of the Company who signed
the Registration Statement), employees and agents and each Person, if any, who
controls the Company, the Initial Purchasers, any underwriter or any other
selling Holder within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act, from and against any and all loss, liability, claim,
damage and expense whatsoever described in the indemnity contained in Section
5(a) hereof, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Registration
Statement (or any amendment thereto) or any Prospectus (or any amendment or
supplement thereto) in reliance upon and in conformity with written information
furnished to the Company by such selling Holder expressly for use in the
Registration Statement (or any amendment thereto), or any such Prospectus (or
any amendment or supplement thereto).

                  (c) Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, enclosing a copy of all papers properly
served on such indemnified party, but failure to so notify an indemnifying party
shall not relieve such indemnifying party from any liability hereunder to the
extent it is not materially prejudiced as a result thereof and in any event
shall not relieve it from any liability which it may have otherwise than on
account of this indemnity agreement. In the case of parties indemnified pursuant
to Section 5(a) above, counsel to the indemnified parties shall be selected by
CIBC and, in the case of parties indemnified pursuant to Section 5(b) above,
counsel to the indemnified parties shall be selected by the Company.
Notwithstanding the foregoing sentence, in case any such action is brought

<PAGE>

                                      -18-


against any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent it may wish, jointly with any other indemnifying
party similarly notified, unless such indemnified party shall have one or more
legal defenses available to it which are not available to the indemnifying
party, to assume the defense thereof, with counsel reasonably satisfactory to
such indemnified party. After notice from the indemnifying party to such
indemnified party of its election as aforesaid to assume the defense thereof and
approval by such indemnified party of counsel appointed to defend such action,
the indemnifying party will not be liable to such indemnified party under this
Section 5 for any legal or other expenses other than reasonable costs of
investigation, subsequently incurred by such indemnified party in connection
with the defense thereof. An indemnifying party may participate at its own
expense in the defense of any such action; provided, however, that counsel to
the indemnifying party shall not (except with the consent of the indemnified
party) also be counsel to the indemnified party. In no event shall the
indemnifying parties be liable for fees and expenses of more than one counsel
(in addition to any local counsel) separate from their own counsel for all
indemnified parties in connection with any one action or separate but similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances. No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any Judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 5 (whether or not the indemnified parties are
actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party.

                  (d) If at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 5(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement.

                  (e) In order to provide for just and equitable contribution in
circumstances under which any of the indemnity provisions set forth in this
Section 5 is for any reason held to be unavailable to the indemnified parties
although applicable in accordance with its terms, the Company and the Holders
shall contribute to the aggregate losses, liabilities, claims, damages and
expenses of the nature contemplated by such indemnity agreement incurred by the


<PAGE>

                                      -19-


Company, and the Holders, as incurred; PROVIDED that no Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person that was not
guilty of such fraudulent misrepresentation. As between the Company and the
Holders, such parties shall contribute to such aggregate losses, liabilities,
claims, damages and expenses of the nature contemplated by such indemnity
agreement in such proportion as shall be appropriate to reflect the relative
fault of the Company, on the one hand, and the Holders, on the other hand, with
respect to the statements or omissions which resulted in such loss, liability,
claim, damage or expense, or action in respect thereof, as well as any other
relevant equitable considerations. The relative fault of the Company, on the one
hand, and of the Holders, on the other hand, shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company, on the one hand, or by or on
behalf of the Holders, on the other, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and the Holders of the Registrable Securities
agree that it would not be just and equitable if contribution pursuant to this
Section 5 were to be determined by PRO RATA allocation or by any other method of
allocation that does not take into account the relevant equitable
considerations. For purposes of this Section 5, each Affiliate of a Holder, and
each director, officer, employee, agent and Person, if any, who controls a
Holder or such Affiliate within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act shall have the same rights to contribution as
such Holder, and each director of the Company, each officer of the Company who
signed the Registration Statement, and each Person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act shall have the same rights to contribution as the Company.

6. RULES 144 AND 144A.

                  The Company shall use its reasonable best efforts to file any
reports required to be filed by it under the Securities Act and the Exchange Act
in a timely manner and, if at any time it is not required to file such reports
but in the past had been required to or did file such reports, it will, upon the
request of any Holder of Warrants or Registrable Securities, make available
other information as required by, and so long as necessary to permit, sales of
its Warrants and Registrable Securities pursuant to Rule 144A. Notwithstanding
the foregoing, nothing in this Section 6 shall be deemed to require the Company
to register any of its securities pursuant to the Exchange Act.

7.       UNDERWRITTEN REGISTRATIONS.

                  If any of the Registrable Securities covered by any
Registration Statement are to be sold in an underwritten public offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be selected by the Company.

<PAGE>

                                      -20-


                  No Person may participate in any underwritten public offering
hereunder unless such person (i) agrees to sell such Registrable Securities on
the basis reasonably provided in any underwriting arrangements approved by the
Persons entitled hereunder to approve such arrangements and (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents required under the terms of such underwriting
arrangements.

                  If the Company has complied with all its obligations under
this Agreement with respect to a Piggy-Back Registration relating to an
underwritten public offering, all holders of Warrants and Registrable
Securities, upon request of the lead managing underwriter with respect to such
underwritten public offering, will be required to not sell or otherwise dispose
of any Warrant or Registrable Security owned by them for a period not to exceed
90 days from the consummation of such underwritten public offering.

8.       MISCELLANEOUS.

                  8.1. REMEDIES. In the event of a breach by the Company, the
Investor or by a Holder of any of its obligations under this Agreement, each
Holder, the Investor and the Company, in addition to being entitled to exercise
all rights granted by law, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company, the
Investor and each Holder agree that monetary damages would not be adequate
compensation for any loss incurred by reason of a breach of any of the
provisions of this Agreement and each hereby further agrees that, in the event
of any action for specific performance in respect of such breach, it shall waive
the defense that a remedy at law would be adequate.

                  8.2. NO CONFLICTING AGREEMENTS. The Company and the Investor
will not enter into any agreement that conflicts with the rights granted to the
Holders and indemnified persons in this Agreement or otherwise conflicts with
the provisions hereof. Without the written consent of the Holders of a majority
of the Registrable Securities, the Company and the Investor shall not grant to
any Person any rights which conflict with the provisions of this Agreement.

                  8.3. AMENDMENTS AND WAIVERS. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, otherwise than with the prior written consent of the Holders
of not less than the Requisite Shares; PROVIDED, HOWEVER, that, for the purposes
of this Agreement, Warrants, Warrant Shares and Registrable Securities that are
owned, directly or indirectly, by the Company, the Investor or any of their
Affiliates are not deemed outstanding. Notwithstanding the foregoing, a waiver
or consent to depart from the provisions hereof with respect to a matter that
relates exclusively to the rights

<PAGE>

                                      -21-


of Holders whose securities are being sold pursuant to a Registration
Statement and that does not directly or indirectly affect the rights of other
Holders may be given by Holders of a majority of the Registrable Securities
being sold by such Holders pursuant to such Registration Statement; PROVIDED,
HOWEVER, that the provisions of this sentence may not be amended, modified or
supplemented except in accordance with the provisions of the immediately
preceding sentence. Notwithstanding the foregoing, no amendment,
modification, supplement, waiver or consent with respect to Section 5 shall
be made or given otherwise than with the prior written consent of each Person
affected thereby.

                  8.4. NOTICES. All notices and other communications provided

of such rights and obligations.

                  8.6. COUNTERPARTS. This Agreement may be executed in any
