(collectively, the "Pledged Collateral"):

          (i)    all Accounts;

<PAGE>

                                      -12-

          (ii)   all Equipment, Goods, Inventory and Fixtures;

          (vii)  all Investment Property;

          (viii) all Intellectual Property Collateral;

          (ix)   the Commercial Tort Claims described on Schedule 15 to the
                 Perfection Certificate;

          (x)    all General Intangibles;

          (xi)   all Deposit Accounts;

          (xii)  all As-extracted collateral;

          (xiii) all Supporting Indebtedness;

          (xiv)  all books and records relating to the Pledged Collateral; and

          (xv)   to the extent not covered by clauses (i) through (xiv) of this
                 this sentence, all other personal property of such Pledgor,
                 whether tangible or intangible, and all Proceeds and products
                 of each of the foregoing and all accessions to, substitutions
                 and replacements for, and rents, profits and products of, each
                 of the foregoing, and any and all Proceeds of any insurance,
                 indemnity, warranty or guaranty payable to such Pledgor from
                 time to time with respect to any of the foregoing.

          Notwithstanding anything to the contrary contained in clauses (i)
through (xv) above, the security interest created by this Agreement shall not
extend to, and the term "Pledged Collateral" shall not include, any Excluded
Property, and (i) the Pledgors shall from time to time (but no more frequently
than quarterly) at the request of the Administrative Agent give written notice
to the Administrative Agent identifying in reasonable detail the Special
Property (and stating in such notice that such Special Property constitutes
"Excluded Property") and shall provide to the Administrative Agent such other
information regarding the Special Property as the Administrative Agent may
reasonably request and (ii) from and after the Effective Date, no Pledgor shall
permit to become effective in any document creating, governing or providing for

<PAGE>

                                      -13-

any permit, lease or license, a provision that would prohibit the creation of
a Lien on such permit, lease or license in favor of the Administrative Agent
unless such Pledgor believes, in its reasonable judgment, that such prohibition
is usual and customary in transactions of such type.

          The security interest granted under this Section 2 is second in
priority to the security interest in the Pledged Collateral granted to
Administrative Agent pursuant to the Senior Security Agreement. However, each
Pledgor and Administrative Agent agree that, as of the date on which that first
priority security interest in the Pledged Collateral (and any subsequent first
priority security interest in the Pledged Collateral granted by Pledgors and to
which Administrative Agent has given its prior written consent, which consent
shall be at the sole discretion of Administrative Agent), terminates and is no
longer in effect, then, as of such date, the security interest granted by
Pledgors under this Agreement shall be a first priority security interest in the
Pledged Collateral.

          SECTION 2.2. Filings. (a) Each Pledgor hereby irrevocably authorizes
the Administrative Agent at any time and from time to time to file in any
relevant jurisdiction any initial financing statements (including fixture
filings) and amendments thereto that contain the information required by Article
9 of the Uniform Commercial Code of each applicable jurisdiction for the filing
of any financing statement or amendment relating to the Pledged Collateral,
including (i) whether such Pledgor is an organization, the type of organization
and any organizational identification number issued to such Pledgor, (ii) any
financing or continuation statements or other documents without the signature of
such Pledgor where permitted by law, including the filing of a financing
statement describing the Pledged Collateral as "all assets in which the Pledgor
now owns or hereafter acquires rights" and (iii) in the case of a financing
statement filed as a fixture filing or covering Pledged Collateral constituting
oil, gas, minerals to be extracted, other As-extracted collateral or timber to
be cut, a sufficient description of the real property to which such Pledged
Collateral relates. Each Pledgor agrees to provide all information described in
the immediately preceding sentence to the Administrative Agent promptly upon
request.

          (b) Each Pledgor hereby ratifies its authorization for the
Administrative Agent to file in any relevant jurisdiction any initial financing
statements or amendments thereto relating to the Pledged Collateral if filed
prior to the date hereof.

          (c) Each Pledgor hereby further authorizes the Administrative Agent to
file filings with the United States Patent and Trademark Office or United States
Copyright Office (or any successor office or any similar office in any other
country), including this Agreement, the Copyright Security Agreement, the Patent
Security Agreement and the Trademark Security Agreement, or other documents for
the purpose of perfecting, confirming, continuing, enforcing or protecting the
security interest granted by such Pledgor hereunder, without the signature of
such Pledgor, and naming such Pledgor, as debtor, and the Administrative Agent,
as secured party.

Pledgor represents and warrants that all certificates, agreements or instruments
representing or evidencing the Securities Collateral in existence on the date
hereof have been delivered to the Administrative Agent pursuant to the terms of
the Senior Security Agreement in suitable form for transfer by delivery or
accompanied by duly executed instruments of transfer or assignment in blank and
that the Administrative Agent has a second priority security interest therein.
Each Pledgor hereby agrees that all certificates, agreements or instruments
representing or evidencing Securities Collateral acquired by such Pledgor after
the date hereof shall promptly upon receipt thereof by such Pledgor be delivered
to and held by or on behalf of the Administrative Agent pursuant hereto, subject
to the terms of the Intercreditor Agreement. All certificated Securities
Collateral shall be in suitable form for transfer by delivery or shall be
accompanied by duly executed instruments of transfer or assignment in blank, all
in form and substance reasonably satisfactory to the Administrative Agent. The
Administrative Agent shall have the right, subject to the terms of the
Intercreditor Agreement, at any time upon the occurrence and during the
continuance of any Event of Default, to endorse, assign or otherwise transfer to
or to register in the name of the Administrative Agent or any of its nominees or
endorse for negotiation any or all of the Securities Collateral, without any
indication that such Securities Collateral is subject to the security interest
hereunder. In addition, upon the occurrence and during the continuance of an
Event of Default, the Administrative Agent shall have the right, subject to the
terms of the Intercreditor Agreement, at any time to exchange certificates
representing or evidencing Securities Collateral for certificates of smaller or
larger denominations.

          SECTION 3.2. Perfection of Uncertificated Securities Collateral. Each
Pledgor represents and warrants that the Administrative Agent has a perfected
second priority security interest in all uncertificated Pledged Securities
pledged by it hereunder that are in existence on the date hereof. Each Pledgor
hereby agrees that if any of the Pledged Securities are at any time not
evidenced by certificates of ownership, then each applicable Pledgor shall, to
the extent permitted by applicable law and the terms of the Intercreditor
Agreement (i) if necessary or desirable to perfect a security interest in such
Pledged Securities, cause such pledge to be recorded on the equityholder
register or the books of the issuer, cause the issuer to execute and deliver to
the Administrative Agent an acknowledgment of the pledge of such Pledged
Securities substantially in the form of Exhibit 1 annexed hereto, execute any
customary pledge forms or other documents necessary or appropriate to complete
the pledge and give the Administrative Agent the right to transfer such Pledged
Securities under the terms hereof and, upon request, provide to the
Administrative Agent an opinion of counsel, in form and substance reasonably
satisfactory to the Administrative Agent, confirming such pledge and perfection
thereof and (ii) use its commercially reasonable efforts to cause such Pledged
Securities to become

<PAGE>

                                      -15-

certificated and delivered to the Administrative Agent in accordance with the
provisions of Section 3.1.

          SECTION 3.3. Financing Statements and Other Filings; Maintenance of
Perfected Security Interest. Each Pledgor represents and warrants that all
filings necessary to perfect the security interest granted by it to the
Administrative Agent in respect of the Pledged Collateral have been delivered to
the Administrative Agent in completed and, to the extent necessary or
appropriate, duly executed form for filing in each governmental, municipal or
other office specified in Schedule 7 annexed to the Perfection Certificate (to
the extent required to be listed on the schedules to the Perfection Certificate
as of the date this representation is made or deemed made). Each Pledgor agrees
that at the sole cost and expense of the Pledgors, (i) such Pledgor will
maintain the security interest created by this Agreement in the Pledged
Collateral as a perfected first priority security interest and shall defend such
security interest against the claims and demands of all persons except Liens
permitted under the Second Lien Term Loan Agreement, (ii) such Pledgor shall
furnish to the Administrative Agent from time to time (but no more frequently
than quarterly) statements and schedules further identifying and describing the
Pledged Collateral and such other reports in connection with the Pledged
Collateral as the Administrative Agent may reasonably request, all in reasonable
detail and (iii) at any time and from time to time, upon the written request of
the Administrative Agent, such Pledgor shall promptly and duly execute and
deliver, and file and have recorded, 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 Agreement and
the rights and powers herein granted, including the filing of any financing
statements, continuation statements and other documents (including this
Agreement) under the Uniform Commercial Code (or other similar laws) in effect
in any jurisdiction with respect to the security interest created hereby and the
execution and delivery of Control Agreements, all in form reasonably
satisfactory to the Administrative Agent and in such offices (including the
United States Patent and Trademark Office and the United States Copyright
Office) wherever required by law to perfect, continue and maintain a valid,
enforceable, first priority security interest in the Pledged Collateral as
provided herein and to preserve the other rights and interests granted to the
Administrative Agent hereunder, as against third parties, with respect to the
Pledged Collateral.

          SECTION 3.4. Other Actions. In order to further insure the attachment,
perfection and priority of, and the ability of the Administrative Agent to
enforce, the Administrative Agent's security interest in the Pledged Collateral,
each Pledgor represents and warrants (as to itself) as follows and agrees, in
each case at such Pledgor's own expense and in accordance with the terms of the
Intercreditor Agreement, to take the following actions with respect to the
following Pledged Collateral:

          (a) Instruments and Tangible Chattel Paper. (i) No amounts payable
     under or in connection with any of the Pledged Collateral are evidenced by
     any Instrument or Tangible Chattel Paper other than such Instruments and
     Tangible Chattel Paper listed in Schedule 12 annexed to the Perfection
     Certificate (to the extent required to be listed on

<PAGE>

                                      -16-

     the schedules to the Perfection Certificate as of the date this
     representation is made or deemed made) and (ii) each Instrument and each
     item of Tangible Chattel Paper listed in Schedule 12 annexed to the
     Perfection Certificate has been properly endorsed, assigned and
     delivered to the Administrative Agent, accompanied by instruments of
     transfer or assignment duly executed in blank. If any amount then payable
     under or in connection with any of the Pledged Collateral shall be
     evidenced by any Instrument or Tangible Chattel Paper, and such amount,
     together with all amounts payable evidenced by any Instrument or Tangible
     Chattel Paper not previously delivered to the Administrative Agent exceeds
     $500,000 in the aggregate for all Pledgors, the Pledgor acquiring such
     Instrument or Tangible Chattel Paper shall forthwith endorse, assign and
     deliver the same to the Administrative Agent, accompanied by such
     instruments of transfer or assignment duly executed in blank as the
     Administrative Agent may from time to time specify.

          (b) Deposit Accounts. (i) Each Pledgor has neither opened nor
     maintains any Deposit Accounts other than the accounts listed in Schedule
     16 annexed to the Perfection Certificate (to the extent required to be
     listed on the schedules to the Perfection Certificate as of the date this
     representation is made or deemed made) and (ii) the Administrative Agent
     has a perfected first priority security interest in each Deposit Account
     listed in Schedule 16 annexed to the Perfection Certificate by Control to
     the extent a fully executed Deposit Account Control Agreement is in effect
     covering such Deposit Account. No Pledgor shall hereafter establish and
     maintain any Deposit Account unless (1) the applicable Pledgor shall have
     given the Administrative Agent 30 days' prior written notice of its
     intention to establish such new Deposit Account with a Bank, (2) such Bank
     shall be reasonably acceptable to the Administrative Agent and (3) if
     requested by the Administrative Agent, such Bank and such Pledgor shall
     have duly executed and delivered to the Administrative Agent a Deposit
     Account Control Agreement with respect to such Deposit Account. Each
     Pledgor agrees that, with respect to each Deposit Account in existence on
     the date hereof and at the time it establishes any additional Deposit
     Accounts it shall (to the extent requested by the Administrative Agent)
     enter into a duly authorized, executed and delivered Deposit Account
     Control Agreement with respect to such Deposit Account. The Administrative
     Agent agrees with each Pledgor that the Administrative Agent shall not give
     any instructions directing the disposition of funds from time to time
     credited to any Deposit Account or withhold any withdrawal rights from such
     Pledgor with respect to funds from time to time credited to any Deposit
     Account unless an Event of Default has occurred and is continuing. The
     provisions of this Section 3.4(b) shall not apply to the Collateral
     Account, or any other Deposit Account for which the Administrative Agent is
     the Bank. No Pledgor shall grant Control of any Deposit Account to any
     person other than the Administrative Agent.

          (c) Investment Property. (i) Each Pledgor (1) has no Securities
     Accounts or Commodity Accounts other than those listed in Schedule 16
     annexed to the Perfection Certificate (to the extent required to be listed
     on the schedules to the Perfection Certificate as of the date this
     representation is made or deemed made) and the

<PAGE>

                                      -17-

     Administrative Agent has a perfected first priority security interest in
     such Securities Accounts and Commodity Accounts by Control, (2) does not
     hold, own or have any interest in any certificated securities or
     uncertificated securities other than those constituting Pledged Securities
     and those maintained in Securities Accounts or Commodity Accounts listed in
     Schedule 16 annexed to the Perfection Certificate (to the extent required
     to be listed on the schedules to the Perfection Certificate as of the date
     this representation is made or deemed made) and (3) as of the date hereof,
     has entered into a duly authorized, executed and delivered Securities
     Account Control Agreement or a Commodity Account Control Agreement with
     respect to each Securities Account or Commodity Account listed in
     Schedule 16 annexed to the Perfection Certificate, as applicable.

          (ii) If any Pledgor shall at any time hold or acquire any certificated
     securities constituting Investment Property, such Pledgor shall promptly
     (a) endorse, assign and deliver the same to the Administrative Agent,
     accompanied by such instruments of transfer or assignment duly executed in
     blank, all in form and substance reasonably satisfactory to the
     Administrative Agent or (b) deliver such securities into a Securities
     Account with respect to which a Control Agreement is in effect in favor of
     the Administrative Agent. If any securities now or hereafter acquired by
     any Pledgor constituting Investment Property are uncertificated and are
     issued to such Pledgor or its nominee directly by the issuer thereof, such
     Pledgor shall promptly notify the Administrative Agent thereof and pursuant
     to an agreement in form and substance reasonably satisfactory to the
     Administrative Agent, either (a) cause the issuer to agree to comply with
     instructions from the Administrative Agent as to such securities, without
     further consent of any Pledgor or such nominee, (b) cause a Security
     Entitlement with respect to such uncertificated security to be held in a
     Securities Account with respect to which the Administrative Agent has
     Control or (c) arrange for the Administrative Agent to become the
     registered owner of the securities. Pledgor shall not hereafter establish
     and maintain any Securities Account or Commodity Account with any
     Securities Intermediary or Commodity Intermediary unless (1) the applicable
     Pledgor shall have given the Administrative Agent 30 days' prior written
     notice of its intention to establish such new Securities Account or
     Commodity Account with such Securities Intermediary or Commodity
     Intermediary, (2) such Securities Intermediary or Commodity Intermediary
     shall be reasonably acceptable to the Administrative Agent and (3) such
     Securities Intermediary or Commodity Intermediary, as the case may be, and
     such Pledgor shall have duly executed and delivered a Control Agreement
     with respect to such Securities Account or Commodity Account, as the case
     may be. Each Pledgor shall accept any cash and Investment Property in trust
     for the benefit of the Administrative Agent and within one (1) Business Day
     of actual receipt thereof, deposit any cash or Investment Property and any
     new securities, instruments, documents or other property by reason of
     ownership of the Investment Property (other than payments of a kind
     described in Section 7.4 hereof) received by it into a Deposit Account or
     Securities Account subject

<PAGE>

                                      -18-

     to Administrative Agent's Control. The Administrative Agent agrees with
     each Pledgor that the Administrative Agent shall not give any Entitlement
     Orders or instructions or directions to any issuer of uncertificated
     securities, Securities Intermediary or Commodity Intermediary, and shall
     not withhold its consent to the exercise of any withdrawal or dealing
     rights by such Pledgor, unless an Event of Default has occurred and is
     continuing, or, after giving effect to any such investment and withdrawal
     rights would occur. The provisions of this Section 3.4(c) shall not apply
     to any Financial Assets credited to a Securities Account for which the
     Administrative Agent is the Securities Intermediary. No Pledgor shall
     grant control over any Investment Property to any person other than the
     Administrative Agent.

          (iii) As between the Administrative Agent and the Pledgors, the
     Pledgors shall bear the investment risk with respect to the Investment
     Property and Pledged Securities, and the risk of loss of, damage to, or the
     destruction of the Investment Property and Pledged Securities, whether in
     the possession of, or maintained as a security entitlement or deposit by,
     or subject to the control of, the Administrative Agent, a Securities
     Intermediary, Commodity Intermediary, any Pledgor or any other person;
     provided, however, that nothing contained in this Section 3.4(c) shall
     release or relieve any Securities Intermediary or Commodity Intermediary of
     its duties and obligations to the Pledgors or any other person under any
     Control Agreement or under applicable law. Each Pledgor shall promptly pay
     all Claims and fees of whatever kind or nature with respect to the
     Investment Property and Pledged Securities pledged by it under this
     Agreement. In the event any Pledgor shall fail to make such payment
     contemplated in the immediately preceding sentence, the Administrative
     Agent may do so for the account of such Pledgor and the Pledgors shall
     promptly reimburse and indemnify the Administrative Agent from all costs
     and expenses incurred by the Administrative Agent under this Section 3.4(c)
     in accordance with Section 12.03 of the Second Lien Term Loan Agreement.

          (d) Electronic Chattel Paper and Transferable Records. No amount under
     or in connection with any of the Pledged Collateral is evidenced by any
     Electronic Chattel Paper or any "transferable record" (as that term is
     defined in Section 201 of the Federal Electronic Signatures in Global and
     National Commerce Act, or in Section 16 of the Uniform Electronic
     Transactions Act as in effect in any relevant jurisdiction) other than
     such Electronic Chattel Paper and transferable records listed in
     Schedule 12 annexed to the Perfection Certificate (to the
     extent required to be listed on the schedules to the Perfection
     Certificate as of the date this representation is made or deemed made).
     If any amount payable under or in connection with any of the Pledged
     Collateral shall be evidenced by any Electronic Chattel Paper or any
     transferable record, the Pledgor acquiring such Electronic Chattel Paper
     or transferable record shall promptly notify the Administrative Agent
     thereof and shall take such action as the Administrative Agent may
     reasonably request to vest in the Administrative Agent control under UCC
     Section 9-105 of such Electronic Chattel Paper or control under
     Section 201 of the Federal Electronic

<PAGE>

                                      -19-

     Signatures in Global and National Commerce Act or, as the case may be,
     Section 16 of the Uniform Electronic Transactions Act, as so in effect in
     such jurisdiction, of such transferable record. The requirement in the
     preceding sentence shall apply to the extent that such amount, together
     with all amounts payable evidenced by Electronic Chattel Paper or any
     transferable record in which the Administrative Agent has not been vested
     control within the meaning of the statutes described in this sentence
     exceeds $500,000 in the aggregate for all Pledgors. The Administrative
     Agent agrees with such Pledgor that the Administrative Agent will arrange,
     pursuant to procedures satisfactory to the Administrative Agent and so long
     as such procedures will not result in the Administrative Agent's loss of
     control, for the Pledgor to make alterations to the Electronic Chattel
     Paper or transferable record permitted under UCC Section 9-105 or, as the
     case may be, Section 201 of the Federal Electronic Signatures in Global and
     National Commerce Act or Section 16 of the Uniform Electronic Transactions
     Act for a party in control to allow without loss of control, unless an
     Event of Default has occurred and is continuing or would occur after taking
     into account any action by such Pledgor with respect to such Electronic
     Chattel Paper or transferable record.

          (e) Letter-of-Credit Rights. If any Pledgor is at any time a
     beneficiary under a Letter of Credit now or hereafter issued in favor of
     such Pledgor, such Pledgor shall promptly notify the Administrative Agent
     thereof and such Pledgor shall, at the request of the Administrative Agent,
     pursuant to an agreement in form and substance reasonably satisfactory to
     the Administrative Agent, either (i) arrange for the issuer and any
     confirmer of such Letter of Credit to consent to an assignment to the
     Administrative Agent of the proceeds of any drawing under the Letter of
     Credit or (ii) arrange for the Administrative Agent to become the
     transferee beneficiary of such Letter of Credit, with the Administrative
     Agent agreeing, in each case, that the proceeds of any drawing under the
     Letter of Credit are to be applied in accordance with the terms of the
     Intercreditor Agreement. The actions in the preceding sentence shall be
     taken to the extent that the amount under such Letter of Credit, together
     with all amounts under Letters of Credit for which the actions described
     above in clause (i) and (ii) have not been taken, exceeds $500,000 in the
     aggregate for all Pledgors.

          (f) Commercial Tort Claims. As of the date hereof each Pledgor hereby
     represents and warrants that it holds no Commercial Tort Claims other than
     those listed in Schedule 15 annexed to the Perfection Certificate (to the
     extent required to be listed on the schedules to the Perfection Certificate
     as of the date this representation is made or deemed made). If any Pledgor
     shall at any time hold or acquire a Commercial Tort Claim having a value
     together with all other Commercial Tort Claims of all Pledgors in which the
     Administrative Agent does not have a security interest in excess of
     $500,000 in the aggregate, such Pledgor shall immediately notify the
     Administrative Agent in writing signed by such Pledgor of the brief details
     thereof and grant to the Administrative Agent in such writing a security
     interest therein and in the Proceeds thereof, all upon the terms

<PAGE>

                                      -20-

     of this Agreement, with such writing to be in form and substance reasonably
     satisfactory to the Administrative Agent.

          (g) Landlord's Access Agreements/Bailee Letters. Each Pledgor shall,
     following the reasonable request of the Administrative Agent, use its
     commercially reasonable efforts to obtain as soon as practicable after the
     date of such request, with respect to each location required by the
     Administrative Agent, where such Pledgor maintains Pledged Collateral, a
     Bailee Letter and/or Landlord Access Agreement, as applicable, and use
     commercially reasonable efforts to obtain a Bailee Letter, Landlord Access
     Agreement and/or landlord's lien waiver, as applicable, from all such
     bailees and landlords, as applicable, who from time to time have possession
     of Pledged Collateral in the ordinary course of such Pledgor's business. A
     waiver of bailee's lien shall not be required if the value of the Pledged
     Collateral held by such bailee is less than $100,000, provided that the
     aggregate value of the Pledged Collateral held by all bailees who have not
     delivered a Bailee Letter is less than $500,000 in the aggregate.

          (h) Motor Vehicles. Upon the request of the Administrative Agent, each
     Pledgor shall deliver to the Administrative Agent originals of the
     certificates of title or ownership for the motor vehicles (and any other
     Equipment covered by Certificates of Title or ownership) owned by it with
     the Administrative Agent listed as lienholder therein. Such requirement
     shall apply to the Pledgors if any such motor vehicle (or any such other
     Equipment) is valued at over $50,000.

          SECTION 3.5. Joinder of Additional Guarantors. The Pledgors shall
cause each Subsidiary of Quest Resource Corporation which, from time to time,
after the date hereof shall be required to pledge any assets to the
Administrative Agent for the benefit of the Secured Parties pursuant to the
provisions of the Second Lien Term Loan Agreement, (a) to execute and deliver to
the Administrative Agent (i) a Joinder Agreement substantially in the form of
Exhibit 3 annexed hereto within thirty (30) Business Days on which it was
acquired or created and (ii) a Perfection Certificate, in each case, within
thirty (30) Business Days of the date on which it was acquired or created or (b)
in the case of a Subsidiary organized outside of the United States required to
pledge any assets to the Administrative Agent, execute and deliver such
documentation as the Administrative Agent shall reasonably request and, in each
case, upon such execution and delivery, such Subsidiary shall constitute a
"Guarantor" and a "Pledgor" for all purposes hereunder with the same force and
effect as if originally named as a Guarantor and Pledgor herein. The execution
and delivery of such Joinder Agreement shall not require the consent of any
Pledgor hereunder. The rights and obligations of each Pledgor hereunder shall
remain in full force and effect notwithstanding the addition of any new
Guarantor and Pledgor as a party to this Agreement.

          SECTION 3.6. Supplements; Further Assurances. Each Pledgor shall take
such further actions, and execute and deliver to the Administrative Agent such
additional assignments, agreements, supplements, powers and instruments, as the
Administrative Agent may in its

<PAGE>

                                      -21-

reasonable judgment deem necessary or appropriate, wherever required by law, in
order to perfect, preserve and protect the security interest in the Pledged
Collateral as provided herein and the rights and interests granted to the
Administrative Agent hereunder, to carry into effect the purposes hereof or
better to assure and confirm unto the Administrative Agent the Pledged
Collateral or permit the Administrative Agent to exercise and enforce its
rights, powers and remedies hereunder with respect to any Pledged Collateral.
Without limiting the generality of the foregoing, each Pledgor shall make,
execute, endorse, acknowledge, file or refile and/or deliver to the
Administrative Agent from time to time upon reasonable request such lists,
descriptions and designations of the Pledged Collateral, copies of warehouse
receipts, receipts in the nature of warehouse receipts, bills of lading,
documents of title, vouchers, invoices, schedules, confirmatory assignments,
supplements, additional security agreements, conveyances, financing statements,
transfer endorsements, powers of attorney, certificates, reports and other
assurances or instruments as the Administrative Agent shall reasonably request.
If an Event of Default has occurred and is continuing, the Administrative Agent
may institute and maintain, subject to the terms of the Intercreditor Agreement,
in its own name or in the name of any Pledgor, such suits and proceedings as the
Administrative Agent may be advised by counsel shall be necessary or expedient
to prevent any impairment of the security interest in or the perfection thereof
in the Pledged Collateral. All of the foregoing shall be at the sole cost and
expense of the Pledgors.

                                   ARTICLE IV

                    REPRESENTATIONS, WARRANTIES AND COVENANTS

           Each Pledgor represents, warrants and covenants as follows:

          SECTION 4.1. Title. Except for the security interest granted to the
Administrative Agent for the ratable benefit of the Secured Parties pursuant to
this Agreement and Liens permitted under the Second Lien Term Loan Agreement,
such Pledgor owns and, as to Pledged Collateral acquired by it from time to time
after the date hereof, will own the rights in each item of Pledged Collateral
pledged by it hereunder free and clear of any and all Liens or claims of others
other than the Liens granted pursuant to the Senior Security Agreement and Liens
permitted under the Second Lien Term Loan Agreement. In addition, no Liens or
claims exist on the Securities Collateral, other than as permitted by Section
9.03 of the Second Lien Term Loan Agreement. Such Pledgor has not filed, nor
authorized any third party to file a financing statement or other public notice
with respect to all or any part of the Pledged Collateral on file or of record
in any public office, except such as have been filed in favor of the
Administrative Agent pursuant to Liens granted under the Senior Security
Agreement, and this Agreement or as are permitted by the Second Lien Term Loan
Agreement or financing statements or public notices relating to the termination
statements listed on Schedule 9 to the

<PAGE>

                                      -22-

Perfection Certificate. No person other than the Administrative Agent has
control or possession of all or any part of the Pledged Collateral, except as
permitted by the Second Lien Term Loan Agreement and the Intercreditor
Agreement.

          SECTION 4.2. Validity of Security Interest. The security interest in
and Lien on the Pledged Collateral granted to the Administrative Agent for the
benefit of the Secured Parties hereunder constitutes (a) a legal and valid
security interest in all the Pledged Collateral securing the payment and
performance of the Indebtedness, and (b) subject to the filings and other
actions described in Schedule 7 annexed to the Perfection Certificate (to the
extent required to be listed on the schedules to the Perfection Certificate as
of the date this representation is made or deemed made), a perfected security
interest in all the Pledged Collateral except for the Pledged Securities. The
security interest and Lien granted to the Administrative Agent for the benefit
of the Secured Parties pursuant to this Agreement in and on the Pledged
Collateral will at all times constitute a perfected, continuing security
interest therein, subject only to Liens granted under the Senior Security
Agreement and to Liens permitted under the Second Lien Term Loan Agreement.

          SECTION 4.3. Defense of Claims; Transferability of Pledged Collateral
Each Pledgor shall, at its own cost and expense, defend title to the Pledged
Collateral pledged by it hereunder and the security interest therein and Lien
thereon granted to the Administrative Agent and the priority thereof against all
claims and demands of all persons, at its own cost and expense, at any time
claiming any interest therein adverse to the Administrative Agent or any other
Secured Party other than Liens permitted under the Second Lien Term Loan
Agreement (other than Contested Liens). There is no agreement, and no Pledgor
shall enter into any agreement or take any other action, that would restrict the
transferability of any of the Pledged Collateral or otherwise impair or conflict
with such Pledgors' obligations or the rights of the Administrative Agent
hereunder.

          SECTION 4.4. Other Financing Statements. It has not filed, nor
authorized any third party to file (nor will there be any) valid or effective
financing statement (or similar statement or instrument of registration under
the law of any jurisdiction) covering or purporting to cover any interest of any
kind in the Pledged Collateral other than financing statements and other
statements and instruments relating to the Liens granted under the Senior
Security Agreement or to Liens permitted under the Second Lien Term Loan
Agreement. So long as any of the Indebtedness remain unpaid, no Pledgor shall
execute, authorize or permit to be filed in any public office any financing
statement (or similar statement or instrument of registration under the law of
any jurisdiction) relating to any Pledged Collateral, except financing
statements and other statements and instruments filed or to be filed in respect
of and covering the security interests granted by such Pledgor to the holder of
the Liens permitted under the Second Lien Term Loan Agreement.

<PAGE>

                                      -23-

          SECTION 4.5. Chief Executive Office; Change of Name; Jurisdiction of
Organization. (a) It shall comply with the provisions of Section 7.16 of the
Second Lien Term Loan Agreement.

          (b) The Administrative Agent may rely on opinions of counsel as to
whether any or all UCC financing statements of the Pledgors need to be amended
as a result of any of the changes to the information provided in Section 5.13(a)
of the Second Lien Term Loan Agreement. If any Pledgor fails to provide
information to the Administrative Agent about such changes on a timely basis,
the Administrative Agent shall not be liable or responsible to any party for any
failure to maintain a perfected security interest in such Pledgor's property
constituting Pledged Collateral, for which the Administrative Agent needed to
have information relating to such changes. The Administrative Agent shall have
no duty to inquire about such changes if any Pledgor does not inform the
Administrative Agent of such changes, the parties acknowledging and agreeing
that it would not be feasible or practical for the Administrative Agent to
search for information on such changes if such information is not provided by
any Pledgor.

          SECTION 4.6. Location of Inventory and Equipment. It shall not move
any Equipment or Inventory to any location other than one within the continental
United States until (i) it shall have given the Administrative Agent not less
than 30 days' prior written notice (in the form of an Officers' Certificate) of
its intention so to do, clearly describing such new location and providing such
other information in connection therewith as the Administrative Agent may
request and (ii) with respect to such new location, such Pledgor shall have
taken all action reasonably satisfactory to the Administrative Agent to maintain
the perfection and priority of the security interest of the Administrative Agent
for the benefit of the Secured Parties in the Pledged Collateral intended to be
granted hereby, including using commercially reasonable efforts to obtain
waivers of landlord's or warehousemen's and/or bailee's liens with respect to
such new location, if applicable, and if reasonably requested by the
Administrative Agent. Such Pledgor agrees to provide the Administrative Agent
with prompt notice following the movement of any Equipment or Inventory to any
location other than one that is listed in the relevant Schedules to the
Perfection Certificate.

          SECTION 4.7. Due Authorization and Issuance. All of the Initial
Pledged Shares have been, and to the extent any Pledged Shares are hereafter
issued, such Pledged Shares will be, upon such issuance, duly authorized,
validly issued and fully paid and non-assessable. All of the Initial Pledged
Interests have been fully paid for, and there is no amount or other obligation
owing by any Pledgor to any issuer of the Initial Pledged Interests in exchange
for or in connection with the issuance of the Initial Pledged Interests or any
Pledgor's status as a partner or a member of any issuer of the Initial Pledged
Interests.

          SECTION 4.8. Consents, etc. In the event that the Administrative Agent
desires to exercise any remedies, voting or consensual rights or attorney-in-
fact powers set forth in this Agreement and determines it necessary to obtain
any approvals or consents of any

<PAGE>

                                      -24-

Governmental Authority or any other person therefor, then, upon the reasonable
request of the Administrative Agent, such Pledgor agrees to use its best efforts
to assist and aid the Administrative Agent to obtain as soon as practicable any
necessary approvals or consents for the exercise of any such remedies, rights
and powers.

          SECTION 4.9. Pledged Collateral. All information set forth herein,
including the schedules annexed hereto, and all information contained in any
documents, schedules and lists heretofore delivered to any Secured Party,
including the Perfection Certificate and the schedules thereto, in connection
with this Agreement, in each case, relating to the Pledged Collateral, is
accurate and complete in all material respects. The Pledged Collateral described
on the schedules annexed to the Perfection Certificate constitutes all of the
property of such type of Pledged Collateral owned or held by the Pledgors.

          SECTION 4.10. Insurance. In the event that the proceeds of any
insurance claim are paid after the Administrative Agent has exercised its right
to foreclose after an Event of Default, such Net Cash Proceeds shall be paid to
the Administrative Agent to satisfy any deficiency remaining after such
foreclosure.

          SECTION 4.11. Payment of Taxes; Compliance with Laws; Contesting
Liens; Claims. Each Pledgor represents and warrants that all Claims imposed upon
or assessed against the Pledged Collateral have been paid and discharged except
to the extent such Claims constitute a Lien not yet due and payable which is a
Contested Lien or a Permitted Collateral Lien. Each Pledgor shall comply with
all laws applicable to the Pledged Collateral the failure to comply with which
would, individually or in the aggregate, have a Material Adverse Effect. Each
Pledgor may at its own expense contest the validity, amount or applicability of
any Claims so long as the contest thereof shall be conducted in accordance with,
and permitted pursuant to the provisions of, the Second Lien Term Loan
Agreement. Notwithstanding the foregoing provisions of this Section 4.11, (i) no
contest of any such obligation may be pursued by such Pledgor if such contest
would expose the Administrative Agent or any other Secured Party to (A) any
possible criminal liability or (B) any additional civil liability for failure to
comply with such obligations unless such Pledgor shall have furnished a bond or
other security therefor satisfactory to the Administrative Agent, or such
Secured Party, as the case may be and (ii) if at any time payment or performance
of any obligation contested by such Pledgor pursuant to this Section 4.11 shall
become necessary to prevent the imposition of remedies against the Pledged
Collateral because of non-payment, such Pledgor shall pay or perform the same in
sufficient time to prevent the imposition of remedies against the Pledged
Collateral in respect of such default or prospective default.

          SECTION 4.12. Access to Pledged Collateral, Books and Records; Other
Information. Upon reasonable request to each Pledgor, the Administrative Agent,
its agents, accountants and attorneys shall have full and free access to visit
and inspect, as applicable, during normal business hours and such other
reasonable times as may be requested by the Administrative Agent all of the
Pledged Collateral and Mortgaged Property including all of the

<PAGE>

                                      -25-

books, correspondence and records of such Pledgor relating thereto. The
Administrative Agent and its representatives may examine the same, take extracts
therefrom and make photocopies thereof, and such Pledgor agrees to render to the
Administrative Agent, at such Pledgor's cost and expense, such clerical and
other assistance as may be reasonably requested by the Administrative Agent with
regard thereto. Such Pledgor shall, at any and all times, within a reasonable
time after written request by the Administrative Agent, furnish or cause to be
furnished to the Administrative Agent, in such manner and in such detail as may
be reasonably requested by the Administrative Agent, additional information with
respect to the Pledged Collateral.

                                   ARTICLE V

               CERTAIN PROVISIONS CONCERNING SECURITIES COLLATERAL

          SECTION 5.1. Pledge of Additional Securities Collateral. Each Pledgor
shall, upon obtaining any Pledged Securities or Intercompany Notes of any
person, accept the same in trust for the benefit of the Administrative Agent and
forthwith deliver to the Administrative Agent a pledge amendment, duly executed
by such Pledgor, in substantially the form of Exhibit 2 annexed hereto (each, a
"Pledge Amendment"), and the certificates and other documents required under
Section 3.1 and Section 3.2 hereof in respect of the additional Pledged
Securities or Intercompany Notes which are to be pledged pursuant to this
Agreement, and confirming the attachment of the Lien hereby created on and in
respect of such additional Pledged Securities or Intercompany Notes. Each
Pledgor hereby authorizes the Administrative Agent to attach each Pledge
Amendment to this Agreement and agrees that all Pledged Securities or
Intercompany Notes listed on any Pledge Amendment delivered to the
Administrative Agent shall for all purposes hereunder be considered Pledged
Collateral.

          SECTION 5.2.  Voting Rights; Distributions; etc.
                        ----------------------------------

          (a) So long as no Event of Default shall have occurred and be
continuing:

          (i) Each Pledgor shall be entitled to exercise any and all voting and
     other consensual rights pertaining to the Securities Collateral or any part
     thereof for any purpose not inconsistent with the terms or purposes hereof,
     the Second Lien Term Loan Agreement or any other document evidencing the
     Indebtedness; provided, however, that no Pledgor shall in any event
     exercise such rights in any manner which could reasonably be expected to
     have a Material Adverse Effect.

          (ii) Each Pledgor shall be entitled to receive and retain, and to
     utilize free and clear of the Lien hereof, any and all Distributions, but
     only if and to the extent made in

<PAGE>

                                      -26-

     accordance with the provisions of the Second Lien Term Loan Agreement;
     provided, however, that any and all such Distributions consisting of rights
     or interests in the form of securities shall be forthwith delivered to the
     Administrative Agent to hold as Pledged Collateral in accordance with the
     terms of the Intercreditor Agreement, and shall, if received by any
     Pledgor, be received in trust for the benefit of the Administrative Agent,
     be segregated from the other property or funds of such Pledgor and be
     forthwith delivered to the Administrative Agent as Pledged Collateral in
     the same form as so received (with any necessary endorsement).

          (b) The Administrative Agent shall be deemed without further action or
formality to have granted to each Pledgor all necessary consents relating to
voting rights and shall, if necessary, upon written request of any Pledgor and
at the sole cost and expense of the Pledgors, from time to time execute and
deliver (or cause to be executed and delivered) to such Pledgor all such
instruments as such Pledgor may reasonably request in order to permit such
Pledgor to exercise the voting and other rights which it is entitled to exercise
pursuant to Section 5.2(a)(i) hereof and to receive the Distributions which it
is authorized to receive and retain pursuant to Section 5.2(a)(ii) hereof.

          (c) Upon the occurrence and during the continuance of any Event of
Default and at all times in accordance with the terms of the Intercreditor
Agreement:

          (i) All rights of each Pledgor to exercise the voting and other
     consensual rights it would otherwise be entitled to exercise pursuant to
     Section 5.2(a)(i) hereof shall cease, and all such rights shall thereupon
     become vested in the Administrative Agent, which shall thereupon have the
     sole right to exercise such voting and other consensual rights.

          (ii) All rights of each Pledgor to receive Distributions which it
     would otherwise be authorized to receive and retain pursuant to Section
     5.2(a)(ii) hereof shall cease and all such rights shall thereupon become
     vested in the Administrative Agent, which shall thereupon have the sole
     right to receive and hold as Pledged Collateral such Distributions.

          (d) Each Pledgor shall, at its sole cost and expense, from time to
time execute and deliver to the Administrative Agent appropriate instruments as
the Administrative Agent may request in order to permit the Administrative Agent
to exercise the voting and other rights which it may be entitled to exercise
pursuant to Section 5.2(a)(i) hereof and to receive all Distributions which it
may be entitled to receive under Section 5.2(a)(ii) hereof.

          (e) All Distributions which are received by any Pledgor contrary to
the provisions of Section 5.2(a)(ii) hereof shall be received in trust for the
benefit of the Administrative Agent, shall be segregated from other funds of
such Pledgor and shall

<PAGE>

                                      -27-

immediately be paid over to the Administrative Agent as Pledged Collateral in
the same form as so received (with any necessary endorsement).

          SECTION 5.3. Defaults, etc. Such Pledgor is not in default in the
payment of any portion of any mandatory capital contribution, if any, required
to be made under any agreement to which such Pledgor is a party relating to the
Pledged Securities pledged by it, and such Pledgor is not in violation of any
other provisions of any such agreement to which such Pledgor is a party, or
otherwise in default or violation thereunder. No Securities Collateral pledged
by such Pledgor is subject to any defense, offset or counterclaim, nor have any
of the foregoing been asserted or alleged against such Pledgor by any person
with respect thereto, and as of the date hereof, there are no certificates,
instruments, documents or other writings (other than the Organizational
Documents and certificates, if any, delivered to the Administrative Agent) which
evidence any Pledged Securities of such Pledgor.

          SECTION 5.4. Certain Agreements of Pledgors As Issuers and Holders of
Equity Interests.

          (a) In the case of each Pledgor which is an issuer of Securities
Collateral, such Pledgor agrees to be bound by the terms of this Agreement
relating to the Securities Collateral issued by it and will comply with such
terms insofar as such terms are applicable to it.

          (b) In the case of each Pledgor which is a partner in a partnership,
limited liability company or other entity, such Pledgor hereby consents to the
extent required by the applicable Organizational Document to the pledge by each
other Pledgor, pursuant to the terms hereof, of the Pledged Interests in such
partnership, limited liability company or other entity and, upon the occurrence
and during the continuance of an Event of Default, to the transfer of such
Pledged Interests to the Administrative Agent or its nominee and to the
substitution of the Administrative Agent or its nominee as a substituted partner
or member in such partnership, limited liability company or other entity with
all the rights, powers and duties of a general partner or a limited partner or
member, as the case may be.

                                   ARTICLE VI

                   CERTAIN PROVISIONS CONCERNING INTELLECTUAL
                               PROPERTY COLLATERAL

          SECTION 6.1. Grant of License. For the purpose of enabling the
Administrative Agent, during the continuance of an Event of Default, to exercise
rights and remedies under Article IX hereof at such time as the Administrative
Agent shall be lawfully entitled to exercise such rights and remedies, and for
no other purpose, each Pledgor hereby

<PAGE>

                                      -28-

grants to the Administrative Agent, to the extent assignable, an irrevocable,
non-exclusive license to use, assign, license or sublicense any of the
Intellectual Property Collateral now owned or hereafter acquired by such
Pledgor, wherever the same may be located. Such license shall include access to
all media in which any of the licensed items may be recorded or stored and to
all computer programs used for the compilation or printout hereof.

          SECTION 6.2. Protection of Administrative Agent's Security. On a
continuing basis, each Pledgor shall, at its sole cost and expense, (i) promptly
following its becoming aware thereof, notify the Administrative Agent of (A) any
materially adverse determination in any proceeding in the United States Patent
and Trademark Office or the United States Copyright Office with respect to any
material Patent, Trademark or Copyright or (B) the institution of any proceeding
or any adverse determination in any federal, state or local court or
administrative body regarding such Pledgor's claim of ownership in or right to
use any of the Intellectual Property Collateral material to the use and
operation of the Pledged Collateral or Mortgaged Property, its right to register
such Intellectual Property Collateral or its right to keep and maintain such
registration in full force and effect, (ii) maintain and protect the
Intellectual Property Collateral material to the use and operation of the
Pledged Collateral or Mortgaged Property as presently used and operated and as
contemplated by the Second Lien Term Loan Agreement, (iii) not permit to lapse
or become abandoned any Intellectual Property Collateral material to the use and
operation of the Pledged Collateral or Mortgaged Property as presently used and
operated and as contemplated by the Second Lien Term Loan Agreement, and not
settle or compromise any pending or future litigation or administrative
proceeding with respect to such Intellectual Property Collateral, in each case
except as shall be consistent with commercially reasonable business judgment,
(iv) upon such Pledgor obtaining knowledge thereof, promptly notify the
Administrative Agent in writing of any event which may be reasonably expected to
materially and adversely affect the value or utility of the Intellectual
Property Collateral or any portion thereof material to the use and operation of
the Pledged Collateral or Mortgaged Property, the ability of such Pledgor or the
Administrative Agent to dispose of the Intellectual Property Collateral or any
portion thereof or the rights and remedies of the Administrative Agent in
relation thereto including a levy or threat of levy or any legal process against
the Intellectual Property Collateral or any portion thereof, (v) not license the
Intellectual Property Collateral other than licenses entered into by such
Pledgor in, or incidental to, the ordinary course of business, or amend or
permit the amendment of any of the licenses in a manner that materially and
adversely affects the right to receive payments thereunder, or in any manner
that would materially impair the value of the Intellectual Property Collateral
or the Lien on and security interest in the Intellectual Property Collateral
intended to be granted to the Administrative Agent for the benefit of the
Secured Parties, without the consent of the Administrative Agent, (vi)
diligently keep adequate records respecting the Intellectual Property Collateral
and (vii) furnish to the Administrative Agent from time to time upon the
Administrative Agent's request therefor reasonably detailed statements and
amended schedules further identifying and describing the Intellectual Property
Collateral and such other materials evidencing or reports

<PAGE>

                                      -29-

pertaining to the Intellectual Property Collateral as the Administrative Agent
may from time to time request.

          SECTION 6.3. After-Acquired Property. If any Pledgor shall, at any
time before the Indebtedness have been paid in full (other than contingent
indemnification obligations which, pursuant to the provisions of the Second Lien
Term Loan Agreement or the Security Instruments, survive the termination
thereof), (i) obtain any rights to any additional Intellectual Property
Collateral or (ii) become entitled to the benefit of any additional Intellectual
Property Collateral or any renewal or extension thereof, including any reissue,
division, continuation, or continuation-in-part of any Intellectual Property
Collateral, or any improvement on any Intellectual Property Collateral, the
provisions hereof shall automatically apply thereto and any such item enumerated
in clause (i) or (ii) of this Section 6.3 with respect to such Pledgor shall
automatically constitute Intellectual Property Collateral if such would have
constituted Intellectual Property Collateral at the time of execution hereof and
be subject to the Lien and security interest created by this Agreement without
further action by any party. Each Pledgor shall promptly (i) provide to the
Administrative Agent written notice of any of the foregoing and (ii) confirm the
attachment of the Lien and security interest created by this Agreement to any
rights described in clauses (i) and (ii) of the immediately preceding sentence
of this Section 6.3 by execution of an instrument in form reasonably acceptable
to the Administrative Agent and the filing of any instruments or statements as
shall be reasonably necessary to preserve, protect or perfect the Administrative
Agent's security interest in such Intellectual Property Collateral. Further,
each Pledgor authorizes the Administrative Agent to modify this Agreement by
amending Schedules 14(a) and 14(b) annexed to the Perfection Certificate to
include any Intellectual Property Collateral acquired or arising after the date
hereof of such Pledgor.

          SECTION 6.4. Litigation. Unless there shall occur and be continuing
any Event of Default, each Pledgor shall have the right to commence and
prosecute in its own name, as the party in interest, for its own benefit and at
the sole cost and expense of the Pledgors, such applications for protection of
the Intellectual Property Collateral and suits, proceedings or other actions to
prevent the infringement, counterfeiting, unfair competition, dilution,
diminution in value or other damage as are necessary to protect the Intellectual
Property Collateral. Upon the occurrence and during the continuance of any Event
of Default, the Administrative Agent shall have the right but shall in no way be
obligated to file applications for protection of the Intellectual Property
Collateral and/or bring suit in the name of any Pledgor, the Administrative
Agent or the Secured Parties to enforce the Intellectual Property Collateral and
any license thereunder. In the event of such suit, each Pledgor shall, at the
reasonable request of the Administrative Agent, do any and all lawful acts and
execute any and all documents requested by the Administrative Agent in aid of
such enforcement and the Pledgors shall promptly reimburse and indemnify the
Administrative Agent for all costs and expenses incurred by the Administrative
Agent in the exercise of its rights under this Section 6.4 in accordance with
Section 12.03 of the Second Lien Term Loan Agreement. In the event that the
Administrative Agent shall elect not to bring suit to enforce the Intellectual
Property Collateral, each Pledgor agrees, at the reasonable request of the
Administrative Agent, to take all commercially

<PAGE>

                                      -30-

reasonable actions necessary, whether by suit, proceeding or other action, to
prevent the infringement, counterfeiting, unfair competition, dilution,
diminution in value of or other damage to any of the Intellectual Property
Collateral by others and for that purpose agrees to diligently maintain any
suit, proceeding or other action against any person so infringing necessary to
prevent such infringement.

                                  ARTICLE VII

                     CERTAIN PROVISIONS CONCERNING ACCOUNTS

          SECTION 7.1. Maintenance of Records. Each Pledgor shall keep and
maintain at its own cost and expense complete records of each Account, in a
manner consistent with prudent business practice, including records of all
payments received, all credits granted thereon, all merchandise returned and all
other documentation relating thereto. Each Pledgor shall, at such Pledgor's sole
cost and expense, upon the Administrative Agent's demand made at any time after
the occurrence and during the continuance of any Event of Default, deliver all
tangible evidence of Accounts, including all documents evidencing Accounts and
any books and records relating thereto to the Administrative Agent or to its
representatives (copies of which evidence and books and records may be retained
by such Pledgor). Upon the occurrence and during the continuance of any Event of
Default, the Administrative Agent may transfer a full and complete copy of any
Pledgor's books, records, credit information, reports, memoranda and all other
writings relating to the Accounts to and for the use by any person that has
acquired or is contemplating acquisition of an interest in the Accounts or the
Administrative Agent's security interest therein without the consent of any
Pledgor.

          SECTION 7.2.  [Reserved].

          SECTION 7.3. Modification of Terms, etc. No Pledgor shall rescind or
cancel any obligations evidenced by any Account in excess of $250,000 or modify
any term thereof or make any adjustment with respect thereto except in the
ordinary course of business consistent with prudent business practice, or extend
or renew any such obligations except in the ordinary course of business
consistent with prudent business practice or compromise or settle any dispute,
claim, suit or legal proceeding relating thereto or sell any Account or interest
therein except in the ordinary course of business consistent with prudent
business practice without the prior written consent of the Administrative Agent.
Each Pledgor shall timely fulfill all obligations on its part to be fulfilled
under or in connection with the Accounts except where failure would not have a
Material Adverse Effect.

          SECTION 7.4. Collection. Each Pledgor shall use commercially
reasonable efforts to collect from the Account Debtor of each of the Accounts,
as and when due in the

<PAGE>

                                      -31-

ordinary course of business and consistent with prudent business practice
(including Accounts that are delinquent, such Accounts to be collected in
accordance with generally accepted commercial collection procedures), any and
all amounts owing under or on account of such Account, and apply forthwith upon
receipt thereof all such amounts as are so collected to the outstanding balance
of such Account, except that any Pledgor may, with respect to an Account, allow
in the ordinary course of business (i) a refund or credit due as a result of
returned or damaged or defective merchandise and (ii) such extensions of time to
pay amounts due in respect of Accounts and such other modifications of payment
terms or settlements in respect of Accounts as shall be commercially reasonable
in the circumstances, all in accordance with such Pledgor's ordinary course of
business consistent with its collection practices as in effect from time to
time. The costs and expenses (including attorneys' fees) of collection, in any
case, whether incurred by any Pledgor, the Administrative Agent or any Secured
Party, shall be paid by the Pledgors.

                                  ARTICLE VIII

                                    TRANSFERS

          SECTION 8.1. Transfers of Pledged Collateral. No Pledgor shall sell,
convey, assign or otherwise dispose of, or grant any option with respect to, any
of the Pledged Collateral pledged by it hereunder except as permitted by the
Second Lien Term Loan Agreement.

                                   ARTICLE IX

                                    REMEDIES

          SECTION 9.1. Remedies. Upon the occurrence and during the continuance
of any Event of Default the Administrative Agent may from time to time exercise
in respect of the Pledged Collateral, in addition to the other rights and
remedies provided for herein or otherwise available to it and at all times in
accordance with the terms of the Intercreditor Agreement, the following
remedies:

          (a) Personally, or by agents or attorneys, immediately take possession
of the Pledged Collateral or any part thereof, from any Pledgor or any other
person who then has possession of any part thereof with or without notice or
process of law, and for that purpose may enter upon any Pledgor's premises where
any of the Pledged Collateral is located, remove such Pledged Collateral, remain
present at such premises to receive copies of all communications and remittances
relating to the Pledged Collateral and use in connection with such removal and
possession any and all services, supplies, aids and other facilities of any
Pledgor;

<PAGE>

                                      -32-

          (b) Demand, sue for, collect or receive any money or property at any
time payable or receivable in respect of the Pledged Collateral including
instructing the obligor or obligors on any agreement, instrument or other
obligation constituting part of the Pledged Collateral to make any payment
required by the terms of such agreement, instrument or other obligation directly
to the Administrative Agent, and in connection with any of the foregoing,
compromise, settle, extend the time for payment and make other modifications
with respect thereto; provided, however, that in the event that any such
payments are made directly to any Pledgor, prior to receipt by any such obligor
of such instruction, such Pledgor shall segregate all amounts received pursuant
thereto in trust for the benefit of the Administrative Agent and shall promptly
(but in no event later than one (1) Business Day after receipt thereof) pay such
amounts to the Administrative Agent;

          (c) Sell, assign, grant a license to use or otherwise liquidate, or
direct any Pledgor to sell, assign, grant a license to use or otherwise
liquidate, any and all investments made in whole or in part with the Pledged
Collateral or any part thereof, and take possession of the proceeds of any such
sale, assignment, license or liquidation;

          (d) Take possession of the Pledged Collateral or any part thereof, by
directing any Pledgor in writing to deliver the same to the Administrative Agent
at any place or places so designated by the Administrative Agent, in which event
such Pledgor shall at its own expense: (A) forthwith cause the same to be moved
to the place or places designated by the Administrative Agent and therewith
delivered to the Administrative Agent, (B) store and keep any Pledged Collateral
so delivered to the Administrative Agent at such place or places pending further
action by the Administrative Agent and (C) while the Pledged Collateral shall be
so stored and kept, provide such security and maintenance services as shall be
necessary to protect the same and to preserve and maintain them in good
condition. Each Pledgor's obligation to deliver the Pledged Collateral as
contemplated in this Section 9.1(iv) is of the essence hereof. Upon application
to a court of equity having jurisdiction, the Administrative Agent shall be
entitled to a decree requiring specific performance by any Pledgor of such
obligation;

          (e) Withdraw all moneys, instruments, securities and other property in
any bank, financial securities, deposit or other account of any Pledgor
constituting Pledged Collateral for application to the Indebtedness as provided
in Article X hereof;

          (f) Retain and apply the Distributions to the Indebtedness as provided
in Article X hereof;

          (g) Exercise any and all rights as beneficial and legal owner of the
Pledged Collateral, including perfecting assignment of and exercising any and
all voting, consensual and other rights and powers with respect to any Pledged
Collateral; and

          (h) All the rights and remedies of a secured party on default under
the UCC, and the Administrative Agent may also in its sole discretion, without
notice except as specified

<PAGE>

                                      -33-

in Section 9.2 hereof, sell, assign or grant a license to use the Pledged
Collateral or any part thereof in one or more parcels at public or private sale,
at any exchange, broker's board or at any of the Administrative Agent's offices
or elsewhere, for cash, on credit or for future delivery, and at such price or
prices and upon such other terms as the Administrative Agent may deem
commercially reasonable. The Administrative Agent or any other Secured Party or
any of their respective Affiliates may be the purchaser, licensee, assignee or
recipient of any or all of the Pledged Collateral at any such sale (to the
extent permitted by law) and shall be entitled, for the purpose of bidding and
making settlement or payment of the purchase price for all or any portion of the
Pledged Collateral sold, assigned or licensed at such sale, to use and apply any
of the Indebtedness owed to such person as a credit on account of the purchase
price of any Pledged Collateral payable by such person at such sale. Each
purchaser, assignee, licensee or recipient at any such sale shall acquire the
property sold, assigned or licensed absolutely free from any claim or right on
the part of any Pledgor, and each Pledgor hereby waives, to the fullest extent
permitted by law, all rights of redemption, stay and/or appraisal which it now
has or may at any time in the future have under any rule of law or statute now
existing or hereafter enacted. The Administrative Agent shall not be obligated
to make any sale of Pledged Collateral regardless of notice of sale having been
given. The Administrative Agent may adjourn any public or private sale from time
to time by announcement at the time and place fixed therefor, and such sale may,
without further notice, be made at the time and place to which it was so
adjourned. Each Pledgor hereby waives, to the fullest extent permitted by law,
any claims against the Administrative Agent arising by reason of the fact that
the price at which any Pledged Collateral may have been sold, assigned or
licensed at such a private sale was less than the price which might have been
obtained at a public sale, even if the Administrative Agent accepts the first
offer received and does not offer such Pledged Collateral to more than one
offeree.

          SECTION 9.2. Notice of Sale. Each Pledgor acknowledges and agrees
that, to the extent notice of sale or other disposition of Pledged Collateral
shall be required by law, ten (10) days' prior notice to such Pledgor of the
time and place of any public sale or of the time after which any private sale or
other intended disposition is to take place shall be commercially reasonable
notification of such matters. No notification need be given to any Pledgor if it
has signed, after the occurrence of an Event of Default, a statement renouncing
or modifying any right to notification of sale or other intended disposition.

          SECTION 9.3. Waiver of Notice and Claims. Each Pledgor hereby waives,
to the fullest extent permitted by applicable law, notice or judicial hearing in
connection with the Administrative Agent's taking possession or the
Administrative Agent's disposition of any of the Pledged Collateral, including
any and all prior notice and hearing for any prejudgment remedy or remedies and
any such right which such Pledgor would otherwise have under law, and each
Pledgor hereby further waives, to the fullest extent permitted by applicable
law: (i) all damages occasioned by such taking of possession, (ii) all other
requirements as to the time, place and terms of sale or other requirements with
respect to the enforcement of the Administrative Agent's rights hereunder and
(iii) all rights of redemption, appraisal, valuation, stay, extension or
moratorium now or hereafter in force under any applicable law. The
Administrative Agent shall

<PAGE>

                                      -34-

not be liable for any incorrect or improper payment made pursuant to this
Article IX in the absence of gross negligence or willful misconduct. Any sale
of, or the grant of options to purchase, or any other realization upon, any
Pledged Collateral shall operate to divest all right, title, interest, claim and
demand, either at law or in equity, of the applicable Pledgor therein and
thereto, and shall be a perpetual bar both at law and in equity against such
Pledgor and against any and all persons claiming or attempting to claim the
Pledged Collateral so sold, optioned or realized upon, or any part thereof,
from, through or under such Pledgor.

          SECTION 9.4. Certain Sales of Pledged Collateral.
                       -----------------------------------

          (a) Each Pledgor recognizes that, by reason of certain prohibitions
contained in law, rules, regulations or orders of any Governmental Authority,
the Administrative Agent may be compelled, with respect to any sale of all or
any part of the Pledged Collateral, to limit purchasers to those who meet the
requirements of such Governmental Authority. Each Pledgor acknowledges that any
such sales may be at prices and on terms less favorable to the Administrative
Agent than those obtainable through a public sale without such restrictions,
and, notwithstanding such circumstances, agrees that any such restricted sale
shall be deemed to have been made in a commercially reasonable manner and that,
except as may be required by applicable law, the Administrative Agent shall have
no obligation to engage in public sales.

          (b) Each Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act, and applicable state securities laws, the
Administrative Agent may be compelled, with respect to any sale of all or any
part of the Securities Collateral and Investment Property, to limit purchasers
to persons who will agree, among other things, to acquire such Securities
Collateral or Investment Property for their own account, for investment and not
with a view to the distribution or resale thereof. Each Pledgor acknowledges
that any such private sales may be at prices and on terms less favorable to the
Administrative Agent than those obtainable through a public sale without such
restrictions (including a public offering made pursuant to a registration
statement under the Securities Act), and, notwithstanding such circumstances,
agrees that any such private sale shall be deemed to have been made in a
commercially reasonable manner and that the Administrative Agent shall have no
obligation to engage in public sales and no obligation to delay the sale of any
Securities Collateral or Investment Property for the period of time necessary to
permit the issuer thereof to register it for a form of public sale requiring
registration under the Securities Act or under applicable state securities laws,
even if such issuer would agree to do so.

          (c) Notwithstanding the foregoing, each Pledgor shall, upon the
occurrence and during the continuance of any Event of Default, at the reasonable
request of the Administrative Agent, for the benefit of the Administrative
Agent, cause any registration, qualification under or compliance with any
Federal or state securities law or laws to be effected with respect to all or
any part of the Securities Collateral as soon as practicable and at the sole
cost and expense of the Pledgors. Each Pledgor will use its commercially
reasonable efforts to cause such registration to be effected (and be kept
effective) and will use its commercially

<PAGE>

                                      -35-

reasonable efforts to cause such qualification and compliance to be effected
(and be kept effective) as may be so requested and as would permit or facilitate
the sale and distribution of such Securities Collateral including registration
under the Securities Act (or any similar statute then in effect), appropriate
qualifications under applicable blue sky or other state securities laws and
appropriate compliance with all other requirements of any Governmental
Authority. Each Pledgor shall use its commercially reasonable efforts to cause
the Administrative Agent to be kept advised in writing as to the progress of
each such registration, qualification or compliance and as to the completion
thereof, shall furnish to the Administrative Agent such number of prospectuses,
offering circulars or other documents incident thereto as the Administrative
Agent from time to time may request, and shall indemnify and shall cause the
issuer of the Securities Collateral to indemnify the Administrative Agent and
all others participating in the distribution of such Securities Collateral
against all claims, losses, damages and liabilities caused by any untrue
statement (or alleged untrue statement) of a material fact contained therein (or
in any related registration statement, notification or the like) or by any
omission (or alleged omission) to state therein (or in any related registration
statement, notification or the like) a material fact required to be stated
therein or necessary to make the statements therein not misleading.

          (d) If the Administrative Agent determines to exercise its right to
sell any or all of the Securities Collateral or Investment Property, upon
written request, the applicable Pledgor shall from time to time furnish to the
Administrative Agent all such information as the Administrative Agent may
request in order to determine the number of securities included in the
Securities Collateral or Investment Property which may be sold by the
Administrative Agent as exempt transactions under the Securities Act and the
rules of the Securities and Exchange Commission thereunder, as the same are from
time to time in effect.

          (e) Each Pledgor further agrees that a breach of any of the covenants
contained in this Section 9.4 will cause irreparable injury to the
Administrative Agent and other Secured Parties, that the Administrative Agent
and the other Secured Parties have no adequate remedy at law in respect of such
breach and, as a consequence, that each and every covenant contained in this
Section 9.4 shall be specifically enforceable against such Pledgor, and such
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 and is continuing.

          SECTION 9.5. No Waiver; Cumulative Remedies.
                       ------------------------------

          (a) No failure on the part of the Administrative Agent to exercise, no
course of dealing with respect to, and no delay on the part of the
Administrative Agent in exercising, any right, power or remedy hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any
such right, power or remedy hereunder preclude any other or further exercise
thereof or the exercise of any other right, power or remedy; nor shall the
Administrative Agent be required to look first to, enforce or exhaust any other
security, collateral or guaranties.

<PAGE>

                                      -36-

The remedies herein provided are cumulative and are not exclusive of any
remedies provided by law.

          (b) In the event that the Administrative Agent shall have instituted
any proceeding to enforce any right, power or remedy under this Agreement by
foreclosure, sale, entry or otherwise, and such proceeding shall have been
discontinued or abandoned for any reason or shall have been determined adversely
to the Administrative Agent, then and in every such case, the Pledgors, the
Administrative Agent and each other Secured Party shall be restored to their
respective former positions and rights hereunder with respect to the Pledged
Collateral, and all rights, remedies and powers of the Administrative Agent and
the other Secured Parties shall continue as if no such proceeding had been
instituted.

          SECTION 9.6. Certain Additional Actions Regarding Intellectual
Property. If any Event of Default shall have occurred and be continuing, upon
the written demand of the Administrative Agent, each Pledgor shall execute and
deliver to the Administrative Agent an assignment or assignments of the
registered Patents, Trademarks and/or Copyrights and Goodwill and such other
documents as are necessary or appropriate to carry out the intent and purposes
hereof. Within five (5) Business Days of written notice thereafter from the
Administrative Agent, each Pledgor shall make available to the Administrative
Agent, to the extent within such Pledgor's power and authority, such personnel
in such Pledgor's employ on the date of the Event of Default as the
Administrative Agent may reasonably designate to permit such Pledgor to
continue, directly or indirectly, to produce, advertise and sell the products
and services sold by such Pledgor under the registered Patents, Trademarks
and/or Copyrights, and such persons shall be available to perform their prior
functions on the Administrative Agent's behalf.

          SECTION 10.2. Application of Proceeds. The proceeds received by the

<PAGE>
                                      -37-

this Agreement, in accordance with the Second Lien Term Loan Agreement and the
Intercreditor Agreement.

                                   ARTICLE XI

                                  MISCELLANEOUS

          SECTION 11.1. Concerning Administrative Agent.
                        -------------------------------

          (a) The actions of the Administrative Agent hereunder are subject to
the provisions of the Second Lien Term Loan Agreement. The Administrative Agent
shall have the right hereunder to make demands, to give notices, to exercise or
refrain from exercising any rights, and to take or refrain from taking action
(including the release or substitution of the Pledged Collateral), in accordance
with this Agreement, Second Lien Term Loan Agreement and the Intercreditor
Agreement. The Administrative Agent may employ agents and attorneys-in-fact in
connection herewith and shall not be liable for the negligence or misconduct of
any such agents or attorneys-in-fact selected by it in good faith. The
Administrative Agent may resign and a successor Administrative Agent may be
appointed in the manner provided in the Second Lien Term Loan Agreement. Upon
the acceptance of any appointment as the Administrative Agent by a successor
Administrative Agent, that successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent under this Agreement, and the retiring
Administrative Agent shall thereupon be discharged from its duties and
obligations under this Agreement. After any retiring Administrative Agent's
resignation, the provisions hereof shall inure to its benefit as to any actions
taken or omitted to be taken by it under this Agreement while it was the
Administrative Agent.

          (b) The Administrative Agent shall be deemed to have exercised
reasonable care in the custody and preservation of the Pledged Collateral in its
possession if such Pledged Collateral is accorded treatment substantially
equivalent to that which the Administrative Agent, in its individual capacity,
accords its own property consisting of similar instruments or interests, it
being understood that neither the Administrative Agent nor any of the Secured
Parties shall have responsibility for (i) ascertaining or taking action with
respect to calls, conversions, exchanges, maturities, tenders or other matters
relating to any Securities Collateral, whether or not the Administrative Agent
or any other Secured Party has or is deemed to have knowledge of such matters or
(ii) taking any necessary steps to preserve rights against any person with
respect to any Pledged Collateral.

          (c) The Administrative Agent shall be entitled to rely upon any
written notice, statement, certificate, order or other document or any telephone
message believed by it to be

<PAGE>
                                      -38-

genuine and correct and to have been signed, sent or made by the proper person,
and, with respect to all matters pertaining to this Agreement and its duties
hereunder, upon advice of counsel selected by it.

          (d) If any item of Pledged Collateral also constitutes collateral
granted to the Administrative Agent under any other deed of trust, mortgage,
security agreement, pledge or instrument of any type, in the event of any
conflict between the provisions hereof and the provisions of such other deed of
trust, mortgage, security agreement, pledge or instrument of any type in respect
of such collateral, the Administrative Agent, in its sole discretion, shall
select which provision or provisions shall control.

          SECTION 11.2. Administrative Agent May Perform; Administrative Agent
Appointed Attorney-in-Fact. If any Pledgor shall fail to perform any covenants
contained in this Agreement (including such Pledgor's covenants to (i) pay the
premiums in respect of all required insurance policies hereunder, (ii) pay
Claims, (iii) make repairs, (iv) discharge Liens or (v) pay or perform any
obligations of such Pledgor under any Pledged Collateral) or if any
representation or warranty on the part of any Pledgor contained herein shall be
breached, the Administrative Agent may (but shall not be obligated to) do the
same or cause it to be done or remedy any such breach, and may expend funds for
such purpose; provided, however, that the Administrative Agent shall in no event
be bound to inquire into the validity of any tax, lien, imposition or other
obligation which such Pledgor fails to pay or perform as and when required
hereby and which such Pledgor does not contest in accordance in accordance with
the provisions of Section 4.11 hereof. Any and all amounts so expended by the
Administrative Agent shall be paid by the Pledgors in accordance with the
provisions of Section 12.03 of the Second Lien Term Loan Agreement. Neither the
provisions of this Section 11.2 nor any action taken by the Administrative Agent
pursuant to the provisions of this Section 11.2 shall prevent any such failure
to observe any covenant contained in this Agreement nor any breach of
representation or warranty from constituting an Event of Default. Each Pledgor
hereby appoints the Administrative Agent its attorney-in-fact, with full
authority in the place and stead of such Pledgor and in the name of such
Pledgor, or otherwise, from time to time in the Administrative Agent's
discretion to take any action and to execute any instrument consistent with the
terms of the Second Lien Term Loan Agreement, this Agreement and the other
Security Instruments which the Administrative Agent may deem necessary or
advisable to accomplish the purposes hereof if any Pledgor shall fail to perform
any covenants or agreements contained in this Agreement. The foregoing grant of
authority is a power of attorney coupled with an interest and such appointment
shall be irrevocable for the term hereof. Each Pledgor hereby ratifies all that
such attorney shall lawfully do or cause to be done by virtue hereof.

          SECTION 11.3. Continuing Security Interest; Assignment. This Agreement
shall create a continuing security interest in the Pledged Collateral and shall
(i) be binding upon the Pledgors, their respective successors and assigns and
(ii) inure, together with the rights and remedies of the Administrative Agent
hereunder, to the benefit of the Administrative Agent and the other Secured
Parties and each of their respective successors, transferees and assigns. No

<PAGE>
                                      -39-

other persons (including any other creditor of any Pledgor) shall have any
interest herein or any right or benefit with respect hereto. Without limiting
the generality of the foregoing clause (ii), any Secured Party may assign or
otherwise transfer any indebtedness held by it secured by this Agreement to any
other person, and such other person shall thereupon become vested with all the
benefits in respect thereof granted to such Secured Party, herein or otherwise,
subject however, to the provisions of the Second Lien Term Loan Agreement and
any Swap Agreement.

          SECTION 11.4. Termination; Release. The Pledged Collateral shall be
released from the Lien of this Agreement in accordance with the provisions of
the Second Lien Term Loan Agreement. Upon termination hereof or any release of
Pledged Collateral in accordance with the provisions of the Second Lien Term
Loan Agreement, the Administrative Agent shall, upon the request and at the sole
cost and expense of the Pledgors, assign, transfer and deliver to Pledgor,
against receipt and without recourse to or warranty by the Administrative Agent
except as to the fact that the Administrative Agent has not encumbered the
released assets, such of the Pledged Collateral to be released (in the case of a
release) as may be in possession of the Administrative Agent and as shall not
have been sold or otherwise applied pursuant to the terms hereof, and, with
respect to any other Pledged Collateral, proper documents and instruments
(including UCC-3 termination statements or releases) acknowledging the
termination hereof or the release of such Pledged Collateral, as the case may
be.

          SECTION 11.5. Modification in Writing. No amendment, modification,
supplement, termination or waiver of or to any provision hereof, nor consent to
any departure by any Pledgor therefrom, shall be effective unless the same shall
be made in accordance with the terms of the Second Lien Term Loan Agreement and
unless in writing and signed by the Administrative Agent. Any amendment,
modification or supplement of or to any provision hereof, any waiver of any
provision hereof and any consent to any departure by any Pledgor from the terms
of any provision hereof shall be effective only in the specific instance and for
the specific purpose for which made or given. Except where notice is
specifically required by this Agreement or any other document evidencing the
Indebtedness, no notice to or demand on any Pledgor in any case shall entitle
any Pledgor to any other or further notice or demand in similar or other
circumstances.

          SECTION 11.6. Notices. Unless otherwise provided herein or in the
Second Lien Term Loan Agreement, any notice or other communication herein
required or permitted to be given shall be given in the manner and become
effective as set forth in the Second Lien Term Loan Agreement, as to any
Pledgor, addressed to it at the address of the Borrowers set forth in the Second
Lien Term Loan Agreement and as to the Administrative Agent, addressed to it at
the address set forth in the Second Lien Term Loan Agreement, or in each case at
such other address as shall be designated by such party in a written notice to
the other party complying as to delivery with the terms of this Section 11.6.

<PAGE>
                                      -40-

          SECTION 11.7. Governing Law, Consent to Jurisdiction and Service of
Process; Waiver of Jury Trial. Section 12.09 of the Second Lien Term Loan
Agreement is incorporated herein, mutatis mutandis, as if a part hereof.

          SECTION 11.8. Severability of Provisions. Any provision hereof 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 or
affecting the validity or enforceability of such provision in any other
jurisdiction.

          SECTION 11.9. Execution in Counterparts. This Agreement and any
amendments, waivers, consents or supplements hereto may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed and delivered shall be deemed to be an original,
but all such counterparts together shall constitute one and the same agreement.

          SECTION 11.10. Business Days. In the event any time period or any date
provided in this Agreement ends or falls on a day other than a Business Day,
then such time period shall be deemed to end and such date shall be deemed to
fall on the next succeeding Business Day, and performance herein may be made on
such Business Day, with the same force and effect as if made on such other day.

          SECTION 11.11. Waiver of Stay. Each Pledgor covenants (to the extent
it may lawfully do so) that in the event that such Pledgor or any property or
assets of such Pledgor shall hereafter become the subject of a voluntary or
involuntary proceeding under the Bankruptcy Code or such Pledgor shall otherwise
be a party to any federal or state bankruptcy, insolvency, moratorium or similar
proceeding to which the provisions relating to the automatic stay under Section
362 of the Bankruptcy Code or any similar provision in any such law is
applicable, then, in any such case, whether or not the Administrative Agent has
commenced foreclosure proceedings under this Agreement, such Pledgor shall not,
and each Pledgor hereby expressly waives their right to (to the extent it may
lawfully do so) at any time insist upon, plead or in any whatsoever, claim or
take the benefit or advantage of any such automatic stay or such similar
provision as it relates to the exercise of any of the rights and remedies
(including any foreclosure proceedings) available to the Administrative Agent as
provided in this Agreement, in any other Security Instrument or any other
document evidencing the Indebtedness. Each Pledgor further covenants (to the
extent it may lawfully do so) that it will not hinder, delay or impede the
execution of any power granted herein to the Administrative Agent, but will
suffer and permit the execution of every such power as though no law relating to
any stay or similar provision had been enacted.

          SECTION 11.12. No Credit for Payment of Taxes or Imposition. Such
Pledgor shall not be entitled to any credit against the principal, premium, if
any, or interest payable under the Second Lien Term Loan Agreement, and such
Pledgor shall not be entitled to any credit

<PAGE>
                                      -41-

against any other sums which may become payable under the terms thereof or
hereof, by reason of the payment of any Tax on the Pledged Collateral or any
part thereof.

          SECTION 11.13. No Claims Against Administrative Agent. Nothing
contained in this Agreement shall constitute any consent or request by the
Administrative Agent, express or implied, for the performance of any labor or
services or the furnishing of any materials or other property in respect of the
Pledged Collateral or any part thereof, nor as giving any Pledgor any right,
power or authority to contract for or permit the performance of any labor or
services or the furnishing of any materials or other property in such fashion as
would permit the making of any claim against the Administrative Agent in respect
thereof or any claim that any Lien based on the performance of such labor or
services or the furnishing of any such materials or other property is prior to
the Lien hereof.

          SECTION 11.14. No Release. Nothing set forth in this Agreement shall
relieve any Pledgor from the performance of any term, covenant, condition or
agreement on such Pledgor's part to be performed or observed under or in respect
of any of the Pledged Collateral or from any liability to any person under or in
respect of any of the Pledged Collateral or shall impose any obligation on the
Administrative Agent or any other Secured Party to perform or observe any such
term, covenant, condition or agreement on such Pledgor's part to be so performed
or observed or shall impose any liability on the Administrative Agent or any
other Secured Party for any act or omission on the part of such Pledgor relating
thereto or for any breach of any representation or warranty on the part of such
Pledgor contained in this Agreement, the Second Lien Term Loan Agreement or the
other Loan Documents, or under or in respect of the Pledged Collateral or made
in connection herewith or therewith. The obligations of each Pledgor contained
in this Section 11.14 shall survive the termination hereof and the discharge of
such Pledgor's other obligations under this Agreement, the Second Lien Term Loan
Agreement and the other Loan Documents.

          SECTION 11.15. Indebtedness Absolute. All obligations of each Pledgor
hereunder shall be absolute and unconditional irrespective of:

          (a) any bankruptcy, insolvency, reorganization, arrangement,
readjustment, composition, liquidation or the like of any Pledgor;

          (b) any lack of validity or enforceability of the Second Lien Term
Loan Agreement, any Swap Agreement or any other Loan Document, or any other
agreement or instrument relating thereto;

          (c) any change in the time, manner or place of payment of, or in any
other term of, all or any of the Indebtedness, or any other amendment or waiver
of or any consent to any departure from the Second Lien Term Loan Agreement, any
Swap Agreement or any other Loan Document or any other agreement or instrument
relating thereto;

<PAGE>
                                      -42-

          (d) any pledge, exchange, release or non-perfection of any other
collateral, or any release or amendment or waiver of or consent to any departure
from any guarantee, for all or any of the Indebtedness;

          (e) any exercise, non-exercise or waiver of any right, remedy, power
or privilege under or in respect hereof, the Second Lien Term Loan Agreement,
any Swap Agreement or any other Loan Document except as specifically set forth
in a waiver granted pursuant to the provisions of Section 11.5 hereof; or

          (f) any other circumstances which might otherwise constitute a defense
available to, or a discharge of, any Pledgor.

                                    GUARANTY

     THIS  GUARANTY  (as the  same may be  amended,  restated,  supplemented  or
otherwise  modified from time to time,  this  "Guaranty") is made as of November
14,  2005,  by each of  BLUESTEM  PIPELINE,  LLC, a Delaware  limited  liability

by executing a  Supplement  hereto in the form  attached  hereto as Annex I, the
"Guarantors"),  in favor of Guggenheim Corporate Funding, LLC, as Administrative
Agent (the  "Administrative  Agent") for the benefit of the Secured  Parties (as
defined in the Security  Agreement).  Each  capitalized term used herein and not

described below.

                                   WITNESSETH:

     WHEREAS, Quest Cherokee, LLC and Quest Resource Corporation  (collectively,
the  "Borrowers")  have entered into a Senior Credit  Agreement  dated as of the
date hereof by and among the  Borrowers,  the  Administrative  Agent and certain
financial  institutions  from  time  to  time  party  thereto  as  Lenders  (the
"Lenders")  (as the same may be amended,  restated,  supplemented  or  otherwise
modified  from time to time,  the "Credit  Agreement")  which  Credit  Agreement
provides,  subject to the terms and conditions thereof, for extensions of credit
and other financial accommodations by the Lenders to the Borrowers;

     WHEREAS,  it is a condition  precedent to the  extensions  of credit by the
Lenders  under the Credit  Agreement  that each of the  Guarantors  execute  and
deliver this Guaranty,  whereby each of the Guarantors,  without  limitation and
with full recourse,  shall  guarantee the payment when due of all  Indebtedness,
including,  without  limitation,  all  principal,  interest,  letter  of  credit
reimbursement obligations and other amounts that shall be at any time payable by

     WHEREAS,  in consideration  of the direct and indirect  financial and other

and other support as the Borrowers may in the future provide, to the Guarantors,
and in order to induce the  Lenders and the  Administrative  Agent to enter into
the  Credit  Agreement,  each of the  Guarantors  is willing  to  guarantee  the
Indebtedness under the Credit Agreement and the other Loan Documents;

<PAGE>

     NOW,  THEREFORE,  in consideration of the foregoing premises and other good
and  valuable  consideration,  the receipt and  sufficiency  of which are hereby
acknowledged, the parties hereto agree as follows:

     Section 1.  Representations,  Warranties and Covenants.  In order to induce
the Administrative  Agent and the Lenders to enter into the Credit Agreement and
to make the Loans and the other financial accommodations to the Borrowers and to
issue the  Letters  of Credit  described  in the Credit  Agreement,  each of the
Guarantors  represents and warrants to each Lender and the Administrative  Agent
as of the date of this  Agreement,  giving  effect  to the  consummation  of the
transactions  contemplated  by the Loan  Documents on the  Effective  Date,  and
thereafter  on each date as  required  by Section  6.02 of the Credit  Agreement
that:

     (a) It (i) is a corporation,  partnership or limited liability company duly
incorporated  or  organized,  as the case may be,  validly  existing and in good
standing under the laws of its  jurisdiction of  incorporation  or organization,
(ii) is  duly  qualified  to do  business  as a  foreign  entity  and is in good
standing under the laws of each jurisdiction where the business by it makes such
qualification  necessary,   except  where  the  failure  to  qualify  could  not
reasonably  be expected  to have a Material  Adverse  Effect,  and (iii) has all
requisite  corporate,   partnership  or  limited  liability  company  power  and
authority,  as the case may be, to own, operate and encumber its property and to
conduct its business in each  jurisdiction  in which its business is  conducted.

     (b)  It  has  the  requisite   corporate,   limited  liability  company  or
partnership,  as applicable,  power and authority and legal right to execute and
deliver this Guaranty and to perform its  obligations  hereunder.  The execution
and  delivery  by it of  this  Guaranty  and  the  performance  by  each  of its
obligations hereunder have been duly authorized by proper proceedings,  and this
Guaranty  constitutes a legal,  valid and binding  obligation of each Guarantor,
enforceable  against such  Guarantor,  in accordance  with its terms,  except as
enforceability  may  be  limited  by  (i)  bankruptcy,   insolvency,  fraudulent
conveyances,  reorganization  or  similar  laws  relating  to or  affecting  the
enforcement of creditors'  rights generally,  (ii) general equitable  principles
(whether considered in a proceeding in equity or at law), and (iii) requirements
of  reasonableness,  good faith and fair dealing.

     (c) Neither the  execution  and  delivery by it of this  Guaranty,  nor the
consummation by it of the transactions herein contemplated, nor compliance by it
with the terms and  provisions  hereof,  will (i)  conflict  with the charter or
other organizational documents of such Guarantor,  (ii) conflict with, result in
a breach of or  constitute  (with or without  notice or lapse of time or both) a
default under any law, rule,  regulation,  order,  writ,  judgment,  injunction,
decree or award  (including,  without  limitation,  any  environmental  property
transfer laws or regulations)  applicable to such Guarantor or any provisions of
any  indenture,  instrument or agreement to which such  Guarantor is party or is
subject or which it or its property is bound or affected, or require termination
of any such  indenture,  instrument  or agreement,  except where such  conflict,
breach or default could not  reasonably  be expected to have a Material  Adverse
Effect,  (iii)  result in or require  the  creation  or  imposition  of any Lien
whatsoever  upon any of the  property  or assets of such  Guarantor,  other than
Liens permitted or created by the Loan  Documents,  or (iv) require any approval
of such  Guarantor's  board of directors or shareholders  or unitholders  except
such as

                                       2

<PAGE>

have been obtained.  Except as set forth in Section 7.03 of the Credit Agreement
the  execution,  delivery and  performance by the Guarantors of each of the Loan
Documents  to which such  Guarantor  is a party do not and will not  require any
registration  with,  consent or approval  of, or notice to, or other  action to,
with  or by  any  governmental  authority,  including  under  any  environmental
property transfer laws or regulations, except filings, consents or notices which
have been made.

     (d) It has no Debt  other than Debt  permitted  under  Section  9.02 of the
Credit Agreement.

     In addition to the  foregoing,  each of the Guarantors  covenants  that, so
long as any Lender has any Commitment  outstanding under the Credit Agreement or
any amount payable under the Credit  Agreement or any other  Indebtedness  shall
remain unpaid,  it will, and, if necessary,  will enable the Borrowers to, fully
comply with those  covenants and agreements of the Borrowers  applicable to such
Guarantor set forth in such Credit Agreement.

     Section 2. The  Guaranty.  Each of the  Guarantors  hereby  unconditionally
guarantees,  jointly  and  severally  with the  other  Guarantors,  the full and
punctual  payment and  performance  when due (whether at stated  maturity,  upon
acceleration or otherwise) of the Indebtedness,  including,  without limitation,
(i) the principal of and interest on each Loan made to each Borrower pursuant to
the  Credit  Agreement,  (ii) any  reimbursement  obligations  in  respect of LC
Disbursements  of each Borrower or the  performance by it of such  reimbursement
obligations,  (iii) all other amounts  payable by each Borrower under the Credit
Agreement  and the other Loan  Documents,  including,  without  limitation,  all
obligations   under  Swap  Agreements,   and  (iv)  the  punctual  and  faithful
performance, keeping, observance, and fulfillment by each Borrower of all of the
agreements, conditions, covenants, and obligations of such Borrower contained in
the Loan Documents (all of the foregoing  being referred to  collectively as the
"Guaranteed Indebtedness").  Upon (x) the failure by any Borrower, or any of its
Affiliates,  as  applicable,  to pay  punctually any such amount or perform such
obligation,  and (y) such  failure  continuing  beyond any  applicable  grace or
notice and cure period, each of the Guarantors agrees that it shall forthwith on
demand pay such amount or perform such obligation at the place and in the manner
specified in the Credit Agreement or the relevant Loan Document, as the case may
be. Each of the  Guarantors  hereby  agrees that this  Guaranty is an  absolute,
irrevocable  and  unconditional  guaranty  of payment  and is not a guaranty  of
collection.

     Section  3.  Guaranty  Unconditional.   The  obligations  of  each  of  the
Guarantors  hereunder shall be unconditional  and absolute and, without limiting
the generality of the foregoing, shall not be released,  discharged or otherwise
affected by:

          (i) any extension, renewal, settlement, indulgence, compromise, waiver
     or release of or with respect to the  Guaranteed  Indebtedness  or any part
     thereof  or  any  agreement  relating  thereto,  or  with  respect  to  any
     obligation of any other  guarantor of any of the  Guaranteed  Indebtedness,
     whether (in any such case) by operation of law or otherwise, or any failure
     or  omission  to enforce  any right,  power or remedy  with  respect to the
     Guaranteed  Indebtedness  or any part  thereof  or any  agreement  relating
     thereto, or

                                       3

<PAGE>

     with  respect  to any  obligation  of  any  other  guarantor  of any of the
     Guaranteed Indebtedness;

          (ii) any  modification  or  amendment of or  supplement  to the Credit
     Agreement,  any Swap  Agreement  or any  other  Loan  Document,  including,
     without limitation, any such amendment which may increase the amount of, or
     the  interest  rates  applicable  to,  any of the  Guaranteed  Indebtedness
     guaranteed hereby;

          (iii)  any  release,  surrender,   compromise,   settlement,   waiver,
     subordination  or  modification,  with  or  without  consideration,  of any
     collateral  securing the Guaranteed  Indebtedness or any part thereof,  any
     other  guaranties  with respect to the Guaranteed  Indebtedness or any part
     thereof,  or any other  obligation  of any person or entity with respect to
     the Guaranteed  Indebtedness or any part thereof,  or any  nonperfection or
     invalidity  of  any  direct  or  indirect   security  for  the   Guaranteed
     Indebtedness;

          (iv) any  change in the  corporate,  partnership  or other  existence,
     structure or ownership of any Borrower or any other guarantor of any of the
     Guaranteed Indebtedness, or any insolvency,  bankruptcy,  reorganization or
     other similar  proceeding  affecting any Borrower or any other guarantor of
     the  Guaranteed  Indebtedness,  or any of their  respective  assets  or any
     resulting  release or  discharge of any  obligation  of any Borrower or any
     other guarantor of any of the Guaranteed Indebtedness;

          (v) the  existence  of any  claim,  setoff or other  rights  which the
     Guarantors may have at any time against any Borrower,  any other  guarantor
     of  any of the  Guaranteed  Indebtedness,  the  Administrative  Agent,  any
     Secured  Party or any other Person,  whether in  connection  herewith or in
     connection  with any unrelated  transactions,  provided that nothing herein
     shall  prevent  the  assertion  of any  such  claim  by  separate  suit  or
     compulsory counterclaim;

          (vi) the enforceability or validity of the Guaranteed  Indebtedness or
     any part  thereof or the  genuineness,  enforceability  or  validity of any
     agreement  relating thereto or with respect to any collateral  securing the
     Guaranteed  Indebtedness  or any part thereof,  or any other  invalidity or
     unenforceability relating to or against any Borrower or any other guarantor
     of any of the Guaranteed Indebtedness, for any reason related to the Credit
     Agreement,  any Swap Agreement or any other Loan Document, or any provision
     of applicable  law or regulation  purporting to prohibit the payment by any
     Borrower or any other guarantor of the Guaranteed  Indebtedness,  of any of
     the Guaranteed Indebtedness;

          (vii) the  failure  of the  Administrative  Agent to take any steps to
     perfect and maintain  any  security  interest in, or to preserve any rights
     to, any security or collateral for the Guaranteed Indebtedness, if any;

          (viii)  the  election  by,  or on  behalf  of,  any one or more of the
     Holders of Secured Indebtedness, in any proceeding instituted under Chapter
     11 of Title 11 of the  United  States  Code (11  U.S.C.  101 et seq.)  (the
     "Bankruptcy  Code"),  of  the  application  of  Section  1111(b)(2)  of the
     Bankruptcy Code;

                                       4

<PAGE>

          (ix) any borrowing or grant of a security interest by any Borrower, as
     debtor-in-possession, under Section 364 of the Bankruptcy Code;

          (x) the disallowance, under Section 502 of the Bankruptcy Code, of all
     or any portion of the claims of the Secured  Parties or the  Administrative
     Agent for repayment of all or any part of the Guaranteed Indebtedness;

          (xi) the  failure of any other  guarantor  to sign or become  party to
     this Guaranty or any amendment, change, or reaffirmation hereof; or

          (xii)  any other  act or  omission  to act or delay of any kind by any
     Borrower,  any  other  guarantor  of  the  Guaranteed   Indebtedness,   the
     Administrative  Agent,  any Secured  Party or any other Person or any other
     circumstance whatsoever which might, but for the provisions of this Section
     3, constitute a legal or equitable discharge of any Guarantor's obligations
     hereunder.

     Section 4.  Discharge Only Upon Payment In Full;  Reinstatement  In Certain
Circumstances.  Each of the  Guarantors'  obligations  hereunder shall remain in
full force and effect until all Guaranteed  Indebtedness  (other than contingent
indemnity obligations and Indebtedness in respect of Swap Agreements) shall have
been paid in full in cash and the  Commitments  and all Letters of Credit issued
under the Credit  Agreement  shall have terminated or expired or, in the case of
all Letters of Credit, are fully  collateralized on terms reasonably  acceptable
to the  Administrative  Agent. If at any time any payment of the principal of or
interest on any Loan or reimbursement  obligation in respect of LC Disbursements
or any other amount  payable by any Borrower or any other party under the Credit
Agreement, any Swap Agreement or any other Loan Document is rescinded or must be
otherwise restored or returned upon the insolvency, bankruptcy or reorganization
of any Borrower or otherwise, each of the Guarantors' obligations hereunder with
respect to such payment  shall be reinstated as though such payment had been due
but not made at such time.

     Section 5. General Waivers; Additional Waivers.

     (A) General Waivers.  Each of the Guarantors  irrevocably waives acceptance
hereof,  presentment,  demand or  action on  delinquency,  protest  and,  to the
fullest extent permitted by law, any notice not provided for herein or under the
other Loan Documents,  as well as any requirement that at any time any action be
taken by any Person against any Borrower,  any other guarantor of the Guaranteed
Indebtedness, or any other Person.

     (B) Additional  Waivers.  Notwithstanding  anything herein to the contrary,
each  of the  Guarantors  hereby  absolutely,  unconditionally,  knowingly,  and
expressly waives:

          (i) any  right  it may  have to  revoke  this  Guaranty  as to  future
     indebtedness or notice of acceptance hereof;

                                       5

<PAGE>

          (ii)(1) notice of acceptance  hereof; (2) notice of any loans or other
     financial  accommodations  made or extended under the Loan Documents or the
     creation or existence  of any  Guaranteed  Indebtedness;  (3) notice of the
     amount  of  the  Guaranteed   Indebtedness,   subject,   however,  to  each
     Guarantor's  right to make  inquiry  of  Administrative  Agent and  Secured
     Parties to  ascertain  the  amount of the  Guaranteed  Indebtedness  at any
     reasonable  time;  (4)  notice  of any  adverse  change  in  the  financial
     condition  of any  Borrower or of any other fact that might  increase  such
     Guarantor's risk hereunder;  (5) notice of presentment for payment, demand,
     protest, and notice thereof as to any instruments among the Loan Documents;
     (6) notice of any  Default or Event of Default;  and (7) all other  notices
     (except  if such  notice  is  specifically  required  to be  given  to such
     Guarantor  hereunder or under the Loan Documents) and demands to which each
     Guarantor might otherwise be entitled;

          (iii) its right, if any, to require the  Administrative  Agent and the
     other Secured  Parties to institute suit against,  or to exhaust any rights
     and remedies which the  Administrative  Agent and the other Secured Parties
     have or may have  against,  the other  Guarantors  or any third  party,  or
     against any collateral provided by the other Guarantors or any third party;
     and each  Guarantor  further  waives any  defense  arising by reason of any
     disability  or other  defense  (other than the defense that the  Guaranteed
     Indebtedness  shall have been fully and finally  performed and indefeasibly
     paid) of the other  Guarantors or by reason of the cessation from any cause
     whatsoever of the liability of the other Guarantors in respect thereof;

          (iv) (a) any rights to assert against the Administrative Agent and the
     other  Secured   Parties  any  defense  (legal  or   equitable),   set-off,
     counterclaim,  or  claim  which  such  Guarantor  may  now or at  any  time
     hereafter  have against the other  Guarantors  or any other party liable to
     the  Administrative  Agent and the other Secured Parties;  (b) any defense,
     set-off, counterclaim, or claim, of any kind or nature, arising directly or
     indirectly  from the  present or future  lack of  perfection,  sufficiency,
     validity, or enforceability of the Guaranteed  Indebtedness or any security
     therefor;  and (c) any defense such Guarantor has to performance hereunder,
     and any right such  Guarantor has to be  exonerated,  arising by reason of:
     the  impairment or suspension of the  Administrative  Agent's and the other
     Secured  Parties'  rights or  remedies  against the other  Guarantors;  the
     alteration by the Administrative Agent and the other Secured Parties of the
     Guaranteed Indebtedness; any discharge of the other Guarantors' obligations
     to the  Administrative  Agent and the other Secured Parties by operation of
     law as a  result  of the  Administrative  Agent's  and  the  other  Secured
     Parties'  intervention or omission; or the acceptance by the Administrative
     Agent and the other Secured Parties of anything in partial  satisfaction of
     the Guaranteed  Indebtedness;  and

          (v) any defense arising by reason of or deriving from (a) any claim or
     defense based upon an election of remedies by the Administrative  Agent and
     the other Secured Parties; or (b) any election by the Administrative  Agent
     and the other  Secured  Parties  under  Section  1111(b) of Title 11 of the
     United  States Code entitled  "Bankruptcy",  as now and hereafter in effect
     (or any  successor  statute),  to limit the  amount  of, or any  collateral
     securing, its claim against the Guarantors:

                                       6

     Section 6. Subordination of Subrogation.  Until the Guaranteed Indebtedness
have been paid in full in cash and  finally  performed  (other  than  contingent
indemnity  obligations and  Indebtedness in respect of the Swap  Agreements) the
Guarantors  (i)  shall  have  no  right  of  subrogation  with  respect  to such
Guaranteed Indebtedness and (ii) waive any right to enforce any remedy which the
Issuing  Bank,  Secured  Parties  or the  Administrative  Agent  now have or may
hereafter have against any Borrower, any endorser or any guarantor of all or any
part of the Indebtedness or any other Person, and until such time the Guarantors
waive  any  benefit  of,  and any  right to  participate  in,  any  security  or
collateral given to the Secured Parties and the  Administrative  Agent to secure
the payment or performance of all or any part of the Guaranteed  Indebtedness or
any  other  liability  of each  Borrower  to the  Secured  Parties.  Should  any
Guarantor  have the  right,  notwithstanding  the  foregoing,  to  exercise  its
subrogation   rights,  each  Guarantor  hereby  expressly  and  irrevocably  (A)
subordinates   any  and  all  rights  at  law  or  in  equity  to   subrogation,
reimbursement,  exoneration,  contribution,  indemnification or set off that the
Guarantor may have to the payment in full in cash of the Guaranteed Indebtedness
until  the  Guaranteed  Indebtedness  are  paid  in full  in  cash  (other  than
contingent indemnity obligations and Indebtedness in respect of Swap Agreements)
and  (B)  waives  any and all  defenses  available  to a  surety,  guarantor  or
accommodation  co-obligor until the Guaranteed  Indebtedness are paid in full in
cash (other than contingent  indemnity  obligations  other than  Indebtedness in
respect of Swap  Agreements).  Each Guarantor  acknowledges and agrees that this
subordination  is intended to benefit the  Administrative  Agent and the Secured
Parties  and shall not limit or  otherwise  affect  such  Guarantor's  liability
hereunder or the  enforceability of this Guaranty,  and that the  Administrative
Agent,  the Secured  Parties  and their  respective  successors  and assigns are
intended  third party  beneficiaries  of the waivers and agreements set forth in
this Section 6.

Section 7. Contribution with Respect to Guaranteed Indebtedness.

     (a) To the  extent  that any  Guarantor  shall  make a payment  under  this
Guaranty (a "Guarantor  Payment") which, taking into account all other Guarantor
Payments then previously or concurrently  made by any other  Guarantor,  exceeds
the  amount  which  otherwise  would have been paid by or  attributable  to such
Guarantor  if each  Guarantor  had paid the  aggregate  Guaranteed  Indebtedness
satisfied by such Guarantor  Payment in the same proportion as such  Guarantor's
"Allocable  Amount" (as defined below) (as determined  immediately prior to such
Guarantor  Payment)  bore  to the  aggregate  Allocable  Amounts  of each of the
Guarantors  as  determined  immediately  prior to the  making of such  Guarantor
Payment,  then,  following  payment in full in cash of the Guarantor Payment and
the Guaranteed  Indebtedness  (other than contingent  indemnity  obligations and
Indebtedness in respect of Swap Agreements),  and all Commitments and Letters of
Credit have terminated or expired or, in the case of all Letters of Credit,  are
fully collateralized on terms reasonably acceptable to the Administrative Agent,
such Guarantor  shall be entitled to receive  contribution  and  indemnification
payments from, and be reimbursed by, each other Guarantor for the amount of such
excess,  pro rata  based  upon  their  respective  Allocable  Amounts  in effect
immediately prior to such Guarantor Payment.

     (b)  As of  any  date  of  determination,  the  "Allocable  Amount"  of any
Guarantor  shall be equal to the maximum amount of the claim which could then be
recovered from such Guarantor under this Guaranty  without  rendering such claim
voidable or avoidable under Section

                                       7

<PAGE>

548 of Chapter 11 of the Bankruptcy Code or under any applicable state Uniform
Fraudulent Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or
common law.

     (c) This Section 7 is intended  only to define the  relative  rights of the
Guarantors,  and  nothing  set forth in this  Section 7 is  intended to or shall
impair the  obligations of the  Guarantors,  jointly and  severally,  to pay any
amounts as and when the same shall become due and payable in accordance with the
terms of this Guaranty.

     (d) The parties  hereto  acknowledge  that the rights of  contribution  and
indemnification hereunder shall constitute assets of the Guarantor or Guarantors
to which such contribution and indemnification is owing.

     (e) The rights of the indemnified Guarantors against other Guarantors under
this Section 7 shall be exercisable  upon the full and  indefeasible  payment of
the Guaranteed  Indebtedness  (other than contingent  indemnity  obligations and
Indebtedness in respect of Swap  Agreements) in full in cash and the termination
or expiry (or in the case of all Letters of Credit full  collateralization),  on
terms reasonably  acceptable to the Administrative Agent, of the Commitments and
all Letters of Credit issued under the Credit Agreement.

     Section 8. Stay of Acceleration. If acceleration of the time for payment of
any amount payable by any Borrower under the Credit Agreement,  any counterparty
to any Swap Agreement or any other Loan Document is stayed upon the  insolvency,
bankruptcy or  reorganization  of any Borrower or any of their  Affiliates,  all
such amounts  otherwise  subject to  acceleration  under the terms of the Credit
Agreement,  any Swap Agreement or any other Loan Document  shall  nonetheless be
payable  by  each  of  the  Guarantors  hereunder  forthwith  on  demand  by the
Administrative Agent.

     Section 9. Notices.  All notices,  requests and other communications to any
party hereunder shall be given in the manner  prescribed in Section 12.01 of the
Credit Agreement with respect to the Administrative  Agent at its notice address
therein and, with respect to any Guarantor,  in the care of the Borrowers at the
address  of the  Borrowers  set forth in the  Credit  Agreement,  or such  other
address or telecopy number as such party may hereafter  specify for such purpose
by notice to the Administrative  Agent in accordance with the provisions of such
Section 12.01.

     Section 10. No Waivers. No failure or delay by the Administrative  Agent or
any Secured Party in exercising any right,  power or privilege  hereunder  shall
operate as a waiver  thereof  nor shall any single or partial  exercise  thereof
preclude  any other or further  exercise  thereof or the  exercise  of any other
right,  power or privilege.  The rights and remedies  provided in this Guaranty,
the Credit  Agreement,  any Swap Agreement and the other Loan Documents shall be
cumulative and not exclusive of any rights or remedies  provided by law.

     Section 11. Successors and Assigns. This Guaranty is for the benefit of the
Administrative Agent and the Secured Parties and their respective successors and
permitted  assigns,  provided,  that no Guarantor shall have any right to assign
its rights or obligations

                                       8

<PAGE>

hereunder  without  the  consent  of the  Administrative  Agent,  and  any  such
assignment  in violation  of this Section 11 shall be null and void;  and in the
event of an assignment of any amounts  payable under the Credit  Agreement,  any
Swap  Agreement or the other Loan  Documents in accordance  with the  respective
terms  thereof,   the  rights  hereunder,   to  the  extent  applicable  to  the
indebtedness  so  assigned,  may be  transferred  with such  indebtedness.  This
Guaranty  shall be  binding  upon each of the  Guarantors  and their  respective
successors and assigns.

     Section 12. Changes in Writing.  Other than in connection with the addition
of  additional  Subsidiaries,   which  become  parties  hereto  by  executing  a
Supplement hereto in the form attached as Annex I, neither this Guaranty nor any
provision hereof may be changed,  waived,  discharged or terminated  orally, but
only in writing signed by each of the Guarantors  and the  Administrative  Agent
with the consent of the requisite Lenders as required in Section 12.02(b) of the
Credit Agreement.

     Section  13.  CHOICE  OF LAW.  THIS  GUARANTY  SHALL BE  GOVERNED  BY,  AND
CONSTRUED IN  ACCORDANCE  WITH,  THE LAWS OF THE STATE OF NEW YORK.

     Section 14. CONSENT TO JURISDICTION; JURY TRIAL.

     (A) CONSENT TO JURISDICTION.  EACH GUARANTOR HEREBY IRREVOCABLY  SUBMITS TO
THE  NON-EXCLUSIVE  JURISDICTION  OF ANY UNITED STATES FEDERAL OR NEW YORK STATE
COURT SITTING IN NEW YORK,  NEW YORK IN ANY ACTION OR PROCEEDING  ARISING OUT OF
OR RELATING TO ANY CREDIT DOCUMENTS AND EACH GUARANTOR HEREBY IRREVOCABLY AGREES
THAT ALL  CLAIMS  IN  RESPECT  OF SUCH  ACTION  OR  PROCEEDING  MAY BE HEARD AND
DETERMINED IN ANY SUCH COURT AND IRREVOCABLY  WAIVES ANY OBJECTION IT MAY NOW OR
HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN
SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT  FORUM.  NOTHING HEREIN SHALL
LIMIT  THE  RIGHT  OF THE  ADMINISTRATIVE  AGENT OR ANY  SECURED  PARTY TO BRING
PROCEEDINGS AGAINST ANY GUARANTOR IN THE COURTS OF ANY OTHER  JURISDICTION.  ANY
JUDICIAL  PROCEEDING BY ANY GUARANTOR  AGAINST THE  ADMINISTRATIVE  AGENT OR ANY
SECURED PARTY OR ANY AFFILIATE OF THE ADMINISTRATIVE  AGENT OR ANY SECURED PARTY
INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED
TO, OR  CONNECTED  WITH THIS  GUARANTY  OR ANY OTHER  CREDIT  DOCUMENT  SHALL BE
BROUGHT ONLY IN A COURT SITTING IN NEW YORK, NEW YORK.

                                       9

<PAGE>

     (B) WAIVER OF JURY TRIAL.   EACH GUARANTOR HEREBY WAIVES TRIAL  BY  JURY IN
ANY JUDICIAL PROCEEDING INVOLVING,  DIRECTLY OR INDIRECTLY,  ANY MATTER (WHETHER
SOUNDING IN TORT,  CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO,
OR CONNECTED  WITH THIS GUARANTY OR ANY OTHER LOAN DOCUMENT OR THE  RELATIONSHIP
ESTABLISHED THEREUNDER.

     Section 15. No Strict  Construction.  The parties hereto have  participated
jointly  in the  negotiation  and  drafting  of this  Guaranty.  In the event an
ambiguity or question of intent or interpretation arises, this Guaranty shall be
construed  as if drafted  jointly by the parties  hereto and no  presumption  or
burden of proof shall arise favoring or  disfavoring  any party by virtue of the
authorship of any provisions of this Guaranty.

     Section  16.  Expenses  of  Enforcement,  Etc.  Subject to the terms of the
Credit  Agreement,  if an Event of Default has occurred and is continuing  under
the Credit Agreement, the Lenders shall have the right at any time to direct the
Administrative  Agent to commence  enforcement  proceedings  with respect to the
Guaranteed  Indebtedness.  The Guarantors agree to reimburse the  Administrative
Agent  and  the  Secured  Parties  for  any  costs  and  out-of-pocket  expenses
(including  reasonable  attorneys'  fees and time charges of  attorneys  for the
Administrative  Agent and the Secured Parties,  which attorneys may be employees
of the  Administrative  Agent or the  Secured  Parties)  paid or incurred by the
Administrative  Agent or any Secured Party in connection with the collection and
enforcement  of  amounts  due  under  the  Loan  Documents,   including  without
limitation this Guaranty. The Administrative Agent agrees to distribute payments
received from any of the  Guarantors  hereunder to the Secured  Parties on a pro
rata basis for application in accordance with the terms of the Credit Agreement.

     Section  17.  Setoff.  At any time after all or any part of the  Guaranteed
Indebtedness  have become due and payable (by  acceleration or otherwise),  each
Secured Party and the Administrative  Agent may, without notice to any Guarantor
and  regardless of the  acceptance of any security or collateral for the payment
hereof,  appropriate  and apply  toward  the  payment  of all or any part of the
Guaranteed  Indebtedness  (i) any  indebtedness  due or to become  due from such
Secured Party or the Administrative Agent to any Guarantor, and (ii) any moneys,
credits or other  property  belonging to any  Guarantor,  at any time held by or
coming into the possession of such Secured Party or the Administrative  Agent or
any of their respective affiliates.

     Section  18.   Financial   Information.   Each  Guarantor   hereby  assumes
responsibility  for keeping itself  informed of the financial  condition of each
Borrower and any and all endorsers and/or other Guarantors of all or any part of
the Guaranteed  Indebtedness,  and of all other  circumstances  bearing upon the
risk of nonpayment of the  Guaranteed  Indebtedness,  or any part thereof,  that
diligent inquiry would reveal, and each Guarantor hereby agrees that none of the
Secured Parties or the  Administrative  Agent shall have any duty to advise such
Guarantor of  information  known to any of them  regarding such condition or any
such circumstances.  In the event any Secured Party or the Administrative Agent,
in its sole  discretion,  undertakes at any time or from time to time to provide
any such  information to a Guarantor,  such Secured Party or the  Administrative
Agent shall be under no obligation (i) to undertake any investigation not a part
of its regular  business  routine,  (ii) to disclose any information  which such
Secured Party or the  Administrative  Agent,  pursuant to accepted or reasonable
commercial finance or banking

                                       10

<PAGE>

practices,  wishes to maintain confidential or (iii) to make any other or future
disclosures of such information or any other information to such Guarantor.

     Section  19.  Severability.  Wherever  possible,  each  provision  of  this
Guaranty  shall be interpreted in such manner as to be effective and valid under
applicable  law, but if any provision of this Guaranty shall be prohibited by or
invalid under such law, such  provision  shall be  ineffective  to the extent of
such  prohibition  or  invalidity  without  invalidating  the  remainder of such
provision or the remaining provisions of this Guaranty.

     Section 20. Merger. This Guaranty represents the final agreement of each of
the  Guarantors  with  respect to the  matters  contained  herein and may not be
contradicted by evidence of prior or contemporaneous  agreements,  or subsequent
oral   agreements,   between  any   Guarantor  and  any  Secured  Party  or  the
Administrative Agent.

     Section 21. Headings. Section headings in this Guaranty are for convenience
of reference  only and shall not govern the  interpretation  of any provision of
this Guaranty.
