                                  INTRODUCTION

   A. The Company and certain of its Subsidiaries (i) have entered into certain
financing transactions with and (ii) prior to the date hereof, have caused
certain other existing letters of credit to be issued by, certain lenders,
financial institutions and other investors (such lenders, financial institutions
and investors, and, to the extent any such financing transaction consists of or
includes a guaranty provided by the Company and/or its Subsidiaries, each of the
beneficiaries of such guaranty (as set forth therein) and each of the entities
more fully described on Schedule II attached hereto collectively, the "Financial
Institutions;" provided, however, except as expressly noted on Schedule II,
neither the Company nor any of its Subsidiaries shall be a deemed a "Financial
Institution;" and provided further, no such lender, financial institution or
investor shall be deemed a "Financial Institution" hereunder until such lender,
financial institution or investor, or an authorized representative of such
lender, financial institution or investor, (A) executes this Guaranty or (B)
expressly acknowledges in an instrument as of even date herewith and to which
the Senior Agent is named a third party beneficiary that any claims under this
Guaranty shall be subject to the subordination provisions contained in Section 7
hereof). Such financing transactions, including those entered into in connection
with the New Credit Agreement, and the existing letters of credit are documented
by certain credit, security, letter of credit and guaranty documents, all as
more fully set forth on Schedule I attached hereto (collectively, as the same
may be modified, replaced, refinanced, amended or supplemented from time to
time, "Credit Documents"). "Borrowers" as used herein shall mean the borrowers
or guarantors under any one or more of the Credit Documents.

   B. It is a condition to certain transactions under the Credit Documents that
the Guarantor shall have executed and delivered this Guaranty.

   C. From time to time the Company has made capital contributions and advances
to the

                                      -1-

Guarantor. The Guarantor is a wholly owned Subsidiary of the Company and will
derive substantial direct or indirect benefit from the transactions contemplated
by the Credit Documents.

   NOW, THEREFORE, the parties hereto have agreed to amend and restate the
Existing Subordinated Guaranty, and the Existing Subordinated Guaranty is hereby
amended and restated in its entirety as follows:

   In order to induce the Financial Institutions to extend certain financing
transactions and letters of credit described in the Credit Documents, the
Guarantor hereby agrees for the ratable benefit of the Financial Institutions as
follows:

Section 1. Guaranty. Guarantor hereby unconditionally and irrevocably guarantees
the punctual payment when due, whether at stated maturity, by acceleration or
otherwise, of the obligations and indebtedness of the Company under the Credit
Documents (such obligations being referred to herein as the "Guaranteed
Obligations"); provided that Guaranteed Obligations shall not include any
increases which occur after the date hereof in the principal amount of the
obligations under the Credit Documents (other than increases in the principal
amount of such obligations that are provided for as of the date of the execution
of this Agreement but not yet funded) and/or the commitments to advance funds or
letters of credit thereunder. Without limiting the generality of the foregoing,
Guarantor's liability shall extend to all amounts which constitute part of the
Guaranteed Obligations even if such Guaranteed Obligations are declared
unenforceable or not allowable in a bankruptcy, reorganization, or similar
proceeding involving a Borrower, or any guarantor of any portion of the
foregoing Guaranteed Obligations (collectively such guarantors together with the
Guarantor and the Borrowers are referred to herein as the "Obligors"). This
Guaranty is a guarantee of payment, not of collection, and Guarantor is
primarily liable for the payment of the Guaranteed Obligations.

Section 2. Limit of Liability. The liabilities and obligations of the Guarantor
hereunder shall be limited to an aggregate amount equal to the largest amount
that would not render such Guarantor's obligations hereunder subject to
avoidance under Section 548 of the United States Bankruptcy Code or any
comparable provisions of any applicable state law.

Section 3. Guaranty Absolute. Guarantor guarantees that the Guaranteed
Obligations will be paid strictly in accordance with the Credit Documents,
regardless of any law, regulation, or order now or hereafter in effect in any
jurisdiction affecting any of such terms or the rights of any Financial
Institution with respect thereto. The obligations of Guarantor under this
Guaranty are independent of the Guaranteed Obligations in each and every
particular, and a separate action or actions may be brought and prosecuted
against any other Obligor, or any other Person regardless of whether any other
Obligor or any other Person is joined in any such action or actions. The
liability of Guarantor under this Guaranty shall be absolute and unconditional
irrespective of:

         (a) The lack of validity or unenforceability of the Guaranteed
Obligations or any Credit Document (other than this Guaranty against the
Guarantor) for any reason whatsoever,

                                      -2-
<PAGE>

including that the act of creating the Guaranteed Obligations is ultra vires,
that the officers or representatives executing the documents creating the
Guaranteed Obligations exceeded their authority, that the Guaranteed Obligations
violate usury or other laws, or that any Obligor has defenses to the payment of
the Guaranteed Obligations, including breach of warranty, statute of frauds,
bankruptcy, statute of limitations, lender liability, or accord and
satisfaction;

         (b) Any change in the time, manner, or place of payment of, or in any
term of, any of the Guaranteed Obligations, any increase, reduction, extension,
or rearrangement of the Guaranteed Obligations, any amendment, supplement, or
other modification of the Credit Documents, or any waiver or consent granted
under the Credit Documents, including waivers of the payment and performance of
the Guaranteed Obligations;

         (c) Any release, exchange, subordination, waste, or other impairment
(including negligent impairment) of any collateral securing payment of the
Guaranteed Obligations; the failure of any Financial Institution or any other
person to exercise diligence or reasonable care in the preservation, protection,
enforcement, sale, or other handling of the collateral; the fact that any
security interest, lien, or assignment related to any collateral for the
Guaranteed Obligations shall not be properly perfected, or shall prove to be
unenforceable or subordinate to any other security interest, lien, or
assignment;

         (d) Any full or partial release of any Obligor (other than the full or
partial release of the Guarantor);

         (e) The failure to apply or the manner of applying collateral or
payments of the proceeds of collateral against the Guaranteed Obligations;

         (f) Any change in the organization or structure of any Obligor; any
change in the shareholders, directors, or officers of any Obligor; or the
insolvency, bankruptcy, liquidation, or dissolution of any Obligor or any
defense that may arise in connection with or as a result of any such insolvency,
bankruptcy, liquidator or dissolution;

         (g) The failure to give notice of any extension of credit made by any
Financial Institution to any Obligor, notice of acceptance of this Guaranty,
notice of any amendment, supplement, or other modification of any Credit
Document, notice of the execution of any document or agreement creating new
Guaranteed Obligations, notice of any default or event of default, however
denominated, under the Credit Documents, notice of intent to demand, notice of
demand, notice of presentment for payment, notice of nonpayment, notice of
intent to protest, notice of protest, notice of grace, notice of dishonor,
notice of intent to accelerate, notice of acceleration, notice of bringing of
suit, notice of any Financial Institution's transfer of the Guaranteed
Obligations, notice of the financial condition of or other circumstances
regarding any Obligor, or any other notice of any kind relating to the
Guaranteed Obligations;

         (h) Any payment or grant of collateral by any Obligor to any Financial
Institution being held to constitute a preference under bankruptcy laws, or for
any reason any Financial Institution is required to refund such payment or
release such collateral;

                                      -3-
<PAGE>

         (i) Any other action taken or omitted which affects the Guaranteed
Obligations, whether or not such action or omission prejudices the Guarantor or
increases the likelihood that the Guarantor will be required to pay the
Guaranteed Obligations pursuant to the terms hereof;

         (j) The fact that all or any of the Guaranteed Obligations cease to
exist by operation of law, including, without limitation, by way of discharge,
limitation or tolling thereof under applicable bankruptcy laws; and

         (k) Any other circumstances which might otherwise constitute a defense
available to, or a discharge of any Obligor (other than the discharge of the
Guarantor).

Section 4. Financial Institutions' Rights and Certain Waivers.

         4.01 Notice and Other Remedies. Guarantor hereby waives promptness,
diligence, notice of acceptance, notice of acceleration, notice of intent to
accelerate, and any other notice with respect to any of the Guaranteed
Obligations and this Guaranty and any requirement that any Financial Institution
protect, secure, perfect or insure any security interest or other Lien or any
property subject thereto or exhaust any right to take any action against any
Obligor or any other Person or any collateral.

         4.02. Waiver of Subrogation and Contribution. (a) Until such time as
the Guaranteed Obligations are irrevocably paid in full, Guarantor hereby
irrevocably waives any claim or other rights which it may acquire against any
Obligor that arise from the Guarantor's Guaranteed Obligations under this
Guaranty or any other Credit Document, including, without limitation, any right
of subrogation (including, without limitation, any statutory rights of
subrogation under Section 509 of the Bankruptcy Code, 11 U.S.C. Section 509),
reimbursement, exoneration, contribution, indemnification, or any right to
participate in any claim or remedy of any Financial Institution against any
Obligor, or any collateral which any Financial Institution now has or acquires.
If any amount shall be paid to Guarantor in violation of the preceding sentence
and the Guaranteed Obligations shall not have been paid in full, such amount
shall be held in trust for the benefit of the Financial Institutions, and shall
promptly be paid to the Financial Institutions to be applied to the Guaranteed
Obligations, whether matured or unmatured. Guarantor acknowledges that it will
receive direct and indirect benefits from the financing arrangements
contemplated by the Credit Documents and that the waiver set forth in this
Section 4.02(a) is knowingly made in contemplation of such benefits.

         (b) Guarantor agrees that, to the extent that any Borrower makes
payments to any Financial Institution, or any Financial Institution receives any
proceeds of collateral, and such payments or proceeds or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside,
or otherwise required to be repaid, then to the extent of such repayment the
Guaranteed Obligations shall be reinstated and continued in full force and
effect as of the date such initial payment or collection of proceeds occurred.
GUARANTOR SHALL INDEMNIFY EACH FINANCIAL INSTITUTION AND EACH AFFILIATE THEREOF
AND THEIR RESPECTIVE DIRECTORS, OFFICERS AND EMPLOYEES FROM, AND DISCHARGE,
RELEASE, AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL ACTUAL LOSSES,
LIABILITIES, GUARANTEED OBLIGATIONS, PENALTIES, ACTIONS, JUDGMENTS, SUITS,
COSTS, DISBURSEMENTS, CLAIMS OR DAMAGES TO WHICH ANY OF THEM MAY BECOME SUBJECT,

                                      -4-
<PAGE>

INSOFAR AS SUCH LOSSES, LIABILITIES, GUARANTEED OBLIGATIONS, PENALTIES, ACTIONS,
JUDGMENTS, SUITS, COSTS, DISBURSEMENTS, CLAIMS OR DAMAGES ARISE OUT OF OR RESULT
FROM (I) ANY ACTUAL OR PROPOSED USE BY ANY BORROWER, OR ANY AFFILIATE OF ANY
BORROWER OF THE PROCEEDS OF ANY ADVANCE, (II) ANY BREACH BY GUARANTOR OF ANY
PROVISION OF THIS GUARANTY OR ANY OTHER CREDIT DOCUMENT, (III) ANY
INVESTIGATION, LITIGATION OR OTHER PROCEEDING (INCLUDING ANY THREATENED
INVESTIGATION OR PROCEEDING) RELATING TO THE FOREGOING, OR (IV) ANY
ENVIRONMENTAL CLAIM OR REQUIREMENT OF ENVIRONMENTAL LAWS CONCERNING OR RELATING
TO THE PRESENT OR PREVIOUSLY-OWNED OR OPERATED PROPERTIES, OR THE OPERATIONS OR
BUSINESS, OF ANY OBLIGOR, AND GUARANTOR SHALL REIMBURSE EACH FINANCIAL
INSTITUTION, AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE DIRECTORS, OFFICERS
AND EMPLOYEES, UPON DEMAND FOR ANY REASONABLE OUT-OF-POCKET EXPENSES (INCLUDING
LEGAL FEES) INCURRED IN CONNECTION WITH ANY SUCH INVESTIGATION, LITIGATION OR
OTHER PROCEEDING; AND EXPRESSLY INCLUDING ANY SUCH LOSSES, LIABILITIES,
GUARANTEED OBLIGATIONS, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS,
DISBURSEMENTS, CLAIMS, DAMAGES, OR EXPENSE INCURRED BY REASON OF THE PERSON
BEING INDEMNIFIED'S OWN NEGLIGENCE, BUT EXCLUDING ANY SUCH LOSSES, LIABILITIES,
GUARANTEED OBLIGATIONS, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS,
DISBURSEMENTS, CLAIMS, DAMAGES OR EXPENSES INCURRED BY REASON OF THE GROSS
NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PERSON TO BE INDEMNIFIED.
NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, ANY PAYMENTS DUE WITH RESPECT
TO THIS SECTION 4.02(b) SHALL BE SUBJECT TO THE PRIOR PAYMENT IN FULL OF THE
SENIOR OBLIGATIONS.

         4.03. Modifications and Amendment to the Credit Documents. As provided
in Section 1 above, certain increases in the principal indebtedness outstanding
under the Credit Documents shall not constitute Guaranteed Obligations. Except
as to the foregoing, the parties to the Credit Documents shall have the right to
amend or modify such Credit Agreements without affecting the rights provided for
in this Guaranty.

         4.04 Limitation on Enforcement. By acceptance of the benefits provided
hereunder, each Financial Institution acknowledges and agrees that it will not
file, or join in or support the filing of, an involuntary proceeding or petition
in bankruptcy against Guarantor; provided such restriction shall not limit any
Financial Institution from making claims in or taking any other actions in
connection with any such proceeding which takes place.

Section 5. Representations and Warranties. Guarantor hereby represents and
warrants as follows:

         (a) Business Existence. Guarantor is duly organized, validly existing,
and in good standing under the laws of Delaware and is in good standing and
qualified to do business in each jurisdiction where its ownership or lease of
property or conduct of its business requires such qualification and where a
failure to be qualified could reasonably be expected to cause a material adverse
effect.

         (b) Power. The execution, delivery, and performance by Guarantor of
this Guaranty and the consummation of the transactions contemplated hereby (a)
are within Guarantor's limited liability company powers, (b) have been duly
authorized by all necessary limited liability company action, and (c) do not
contravene (i) Guarantor's certificate of formation or limited liability company
agreement or (ii) any law or any contractual restriction binding on or affecting

<PAGE>

         (c) Authorization and Approvals. No authorization or approval or other
action by, and no notice to or filing with, any Governmental Authority is
required for the due execution, delivery and performance by the Guarantor of
this Guaranty or the consummation of the transactions contemplated hereby.

         (d) Enforceable Obligations. This Guaranty has been duly executed and
delivered by Guarantor. This Guaranty is the legal, valid, and binding
obligation of Guarantor and is enforceable against Guarantor in accordance with
its terms, except as such enforceability may be limited by any applicable
bankruptcy, insolvency, reorganization, moratorium, or similar law affecting
creditors' rights generally.

         (e) Solvency. After giving effect to this Guaranty and the concurrent
amendments to various financing arrangements and agreements of the Company and
its Subsidiaries and the asset sales by the Company and/or its Subsidiaries that
were consummated by the Company on or about July 31, 2002, Guarantor,
individually and together with its Subsidiaries, is Solvent.

Section 6. Covenants.

         (a) In the event that a Financial Institution wishes to enforce the
guarantee contained in Section 1 hereof against Guarantor, then subject in all
cases to Section 7 below, it shall make written demand for payment from
Guarantor, provided that no such demand shall be required if Guarantor is in
bankruptcy, liquidation, or other insolvency proceedings, and provided that
failure by a Financial Institution to make such demand shall not affect
Guarantor's obligations under this Guaranty.

         (b) From and after the repayment in full of the Senior Obligations, the
following shall apply: All indebtedness of Guarantor to another Obligor or any
Borrower or any Subsidiary of a Borrower shall be subordinated to all
indebtedness of Guarantor to any Financial Institution under any of the Credit
Documents (the "Designated Indebtedness"), as follows:

                  (i) In the event of any insolvency or bankruptcy proceedings,
         or any receivership liquidation, reorganization, or other similar
         proceedings in connection therewith, relative to Guarantor, or to its
         property, or in the event of any proceedings for voluntary liquidation,
         dissolution, or other winding up of Guarantor, whether or not involving
         insolvency or bankruptcy, then the holders of the Designated
         Indebtedness shall be entitled to receive payment in full of all
         Designated Indebtedness before any Obligor or any Subsidiary of a
         Borrower shall receive any payment on account of principal or interest
         due such Person from Guarantor;

                  (ii) After the occurrence and during the continuance of any
         default or event of default, however denominated, under any Credit
         Document (an "Event of Default"), Guarantor shall not exercise or
         attempt to exercise any right of offset or counterclaim in respect of
         any of its obligations to any other Obligor or any Subsidiary of a
         Borrower if the effect thereof shall be to reduce the amount of any
         payment to which the holders of

                                      -6-
<PAGE>

         Designated Indebtedness would be entitled in the absence of such offset
         or counterclaim; and if and to the extent that, notwithstanding the
         foregoing, Guarantor is required by any mandatory provisions of law to
         exercise any such right of offset or counterclaim, each reduction of
         the amount owing on the account of the principal of or premium (if any)
         or interest owed to any Obligor or any Subsidiary of a Borrower by
         reason of such offset or counterclaim shall be deemed to be a payment
         by Guarantor in a like amount in respect of such amounts which clause
         (iv) below shall apply;

                  (iii) Following the occurrence and during the continuance of
         any Event of Default, (A) payment of the principal or interest upon any
         indebtedness owed to any Obligor or any Subsidiary of a Borrower shall
         not be made thereunder until payment in full of all Designated
         Indebtedness has been made and (B) the holders of the Designated
         Indebtedness shall be entitled to receive payment in full of all
         Designated Indebtedness prior to the entitlement of any Obligor or any
         Subsidiary of a Borrower to receive any payment of the principal or
         interest (except for payments which have been made prior to the
         occurrence of such event of default);

                  (iv) If, notwithstanding the provisions of the foregoing
         subparagraphs (i) through (iii), any payment or distribution on any
         indebtedness shall be received by Guarantor or any Obligor or any
         Subsidiary of a Borrower while an Event of Default exists and before
         the holders of the Designated Indebtedness shall have received payment
         in full on all Designated Indebtedness, such payment or distribution
         shall be (and shall be deemed to be) held in trust for the benefit of,
         and shall be paid over or delivered or transferred to, the holders of
         the Designated Indebtedness for application to the payment of all
         Designated Indebtedness held by such holder to the extent necessary to
         satisfy such Designated Indebtedness; and

                  (v) No present or future holder of Designated Indebtedness
         shall be prejudiced in its right to enforce subordination of any
         Obligor or any Subsidiary of a Borrower by any act or failure to act on
         the part of Guarantor whether or not such act or failure shall give
         rise to any right of rescission or other claim or cause of action on
         the part of Guarantor or any Borrower or any Subsidiary of a Borrower.
         The provisions of the foregoing paragraphs with respect to
         subordination are solely for the purpose of defining the relative
         rights of the holders of Designated Indebtedness on the one hand, and
         any Obligor or any Subsidiary of a Borrower on the other hand, and none
         of such provisions shall impair, as between Guarantor and any Obligor
         or any Subsidiary of a Borrower, the obligation of Guarantor, which is
         unconditional and absolute, to pay to any Obligor or any Subsidiary of
         a Borrower the principal and interest of any indebtedness in accordance
         with its terms, nor shall anything in such provisions prevent any other
         Obligor or any Subsidiary of a Borrower from exercising all remedies
         otherwise permitted by applicable law or hereunder upon default
         hereunder, subject to the rights of holders of Designated Indebtedness
         under such provisions.

         The terms of Section 6(b) shall not be applicable during the period
         that the Senior Obligations remain outstanding.

                                      -7-
<PAGE>

         (c) The Guarantor will not create, assume, incur or suffer to exist any
Lien on or in respect of any of its property, whether now owned or hereafter
acquired, or assign or otherwise convey any right to receive income except
pursuant to documents entered into in connection with the Senior Credit
Documents or as otherwise permitted therein.

         (d) The Guarantor will not create, incur, assume or suffer to exist any
Debt other than Debt that (i) is created pursuant to this Guaranty, (ii)
constitutes Senior Obligations or (iii) is permitted pursuant to the Senior
Credit Documents.

         (e) The Guarantor will not create, incur, assume or suffer to exist any
obligation or liability other than (i) Debt permitted under clause (d) above and
(ii) any obligation or liability that is permitted pursuant to the Senior Credit
Documents on the date hereof.

defined below) (an "Event of Default"), each Financial Institution shall pay to
the Senior Agent (as defined below) any payment made by Guarantor pursuant to
this Guaranty of all or any part of the Guaranteed Obligations and any amount so
paid to the Senior Agent shall be applied to payment of the Senior Obligations.

Obligations received in violation of any of the provisions hereof shall be
deemed to have been received by the Financial Institutions as trustee for the
Senior Agent and shall be paid over to the Senior Agent immediately on account
of the Senior Obligations. The Financial Institutions agree not to ask, demand,
sue for, take or receive from Guarantor, directly or indirectly, in cash or
other property or by set-off or in any other manner (including, without
limitation, from or by way of collateral), any payment by the Guarantor under
this Guaranty unless and until the Senior Obligations are paid in full. Senior
Agent is hereby authorized to demand specific performance by the Financial
Institutions of its agreements set forth in this Section at any time the
Financial Institutions shall have failed to comply with any of the provisions of
this Section. The Financial Institutions hereby irrevocably waive any defense
based on the adequacy of remedies at law, which might be asserted as a bar to
such remedy of specific performance.

         (b) The Financial Institutions shall only be entitled to take any
remedial or enforcement actions against the Guarantor under this Guaranty upon
or after the earliest to occur of (i) the payment in full of all Senior
Obligations or (ii) the taking of any remedial or enforcement remedy by the
Senior Agent.

         8.04. Right of Set-Off. From and after the repayment in full of the
Senior Obligations, the following shall apply: Upon the occurrence and during
the continuance of any default or event of default however described under a
Credit Document, each Financial Institution party to such Credit Document is
hereby authorized at any time, to the fullest extent permitted by law, to set
off and apply any deposits (general or special, time or demand, provisional or
final) and other indebtedness owing by such Financial Institution to the
accounts of the Guarantor against any and all of the obligations of the
Guarantor under this Guaranty, irrespective of whether or not such Financial
Institution shall have made any demand under this Guaranty and although such
obligations may be contingent and unmatured. Each Financial Institution agrees
promptly to notify the Guarantor after any such set-off and application made by
such Financial Institution provided that the failure to give such notice shall
not affect the validity of such set-off and application. The rights of the

Financial Institutions may have.

         8.05. Continuing Guaranty; Assignments under Credit Documents. This

respective successors and assigns, (c) inure to the benefit of, and be
enforceable by, each of the Financial Institutions and their respective
successors, transferees and assigns, and (d) not be terminated by Guarantor or
any other Person. Without limiting the generality of the foregoing clause (c),
any Financial Institution may assign or otherwise transfer all or any portion of
its rights and Guaranteed Obligations and the assignee shall thereupon become
vested with all the benefits in respect thereof granted to such Financial
Institution herein or otherwise. Upon the indefeasible payment in full and
termination of the Guaranteed Obligations, each guaranty granted hereby shall
terminate and all rights hereunder shall revert to the Guarantor to the extent
such rights have not been applied pursuant to the terms hereof. Upon any such
termination, each Financial Institution will, at Guarantor's expense, execute
and deliver to Guarantor such documents as Guarantor shall reasonably request
and take any other actions reasonably requested to evidence or effect such
termination. This Guaranty is not assignable by Guarantor without the written
consent of each Financial Institution.

<PAGE>

         For purposes of determining the Applicable Margin, with respect to the
         debt ratings criteria: (i) if neither Moody's nor S&P shall have in
         effect a rating for Index Debt (other than by reason of the
         circumstances referred to in the last sentence of this definition),
         then both such rating agencies will be deemed to have established
         ratings for Index Debt in Category 5; (ii) if only one of Moody's or
         S&P shall have in effect a rating for Index Debt, the Company and the
         Lenders will negotiate in good faith to agree upon another rating
         agency to be substituted by an agreement for the rating agency which
         shall not have a rating in effect, and in the absence of such agreement
         the Applicable Margin will be determined by reference to the available
         rating; (iii) except as expressly provided in the above table, if the
         ratings established by Moody's and S&P shall differ by (x) one
         Category, the Applicable Margin shall be determined by reference to the
         numerically higher Category, and (y) two or more Categories the
         Applicable Margin shall be determined by reference to the numerical
         Category which is the numerically highest such Category (for example,
         if the rating from S&P is in Category 2 and the rating from Moody's is
         in Category 5, the Applicable Margin shall be determined by reference
         to Category 5); and (iv) if any rating established by Moody's or S&P
         shall be changed (other than as a result of a change in the rating
         system of either Moody's or S&P), such change shall be effective as of
         the date on which such change is first announced by the rating agency
         making such change. If the rating system of either Moody's or S&P shall
         change prior to the payment in full of the Obligation, the Company and
         the Lenders shall negotiate in good faith to amend the references to
         specific ratings in this definition to reflect such changed rating
         system. If both Moody's and S&P shall cease to be in the business of
         rating corporate debt obligations, the Company and the Lenders shall
         negotiate in good faith to agree upon a substitute rating agency and to
         amend the references to specific ratings in this definition to reflect
         the ratings used by such substitute rating agency, and the Applicable
         Margin shall continue to be based upon the ratings Category in effect
         immediately prior to such event until such agreement on a substitute
         rating agency is reached.

         under the Primary Credit Agreement pursuant to this SECTION 3.2(c)
         shall cause the Commitments under the Primary Credit Agreement as so
         reduced to be less than the aggregate outstanding principal amount of
         the "Advances" under the Primary Credit Agreement (such positive
         difference between such Commitments and such outstanding Advances being
         referred to herein as the "Excess Amount"), the Company shall repay an
         aggregate principal amount not less than such Excess Amount, and except
         as set forth in this proviso, the obligation of the Company to apply
         Net Cash Proceeds to the reduction of the Commitments of the Banks
         under the Primary Credit Agreement shall not require any payments to
         such Banks. Any and all amounts required to be prepaid on the Principal
         Debt pursuant to this SECTION 3.2(c) shall be made together with (1)
         all accrued and unpaid interest on the principal amount so prepaid and
         (2) any Consequential Loss arising as a result thereof.

                  (d) After giving Administrative Agent advance written notice
         of the intent to prepay, the Company may voluntarily prepay all or any
         part of the Principal Debt from time to time and at any time, in whole
         or in part, without premium or penalty; provided that: (i) such notice
         must be received by Administrative Agent by 1:00 p.m. New York, New
         York time on (A) the third Business Day preceding the date of
         prepayment of a Eurodollar Rate Borrowing, and (B) one Business Day
         preceding the date of prepayment of a Base Rate Borrowing; (ii) each
         such partial prepayment must be in a minimum amount of at least
         $5,000,000 or a greater integral multiple of $1,000,000 thereof (if a
         Eurodollar Rate Borrowing or a Base Rate Borrowing); and (iii) all
         accrued interest on the Obligation to be prepaid must also be paid in
         full, to the date of such prepayment. Each notice of prepayment shall
         specify the prepayment date, the Type of Borrowing(s) and amount(s) of
         such

<PAGE>

         Borrowing(s) to be prepaid and shall constitute a binding obligation of
         the Company to make a prepayment on the date stated therein.

         3.3 Interest Options. Except where specifically otherwise provided,
Borrowings shall bear interest at a rate per annum equal to the lesser of (a) as
to the respective Type of Borrowing (as designated by the Company in accordance
with this Agreement), the Base Rate plus the Applicable Margin for Base Rate
Borrowings, the Adjusted Eurodollar Rate plus the Applicable Margin for
Eurodollar Rate Borrowings, as the case may be, and (b) the Maximum Rate. Each
change in the Base Rate or the Maximum Rate subject to the terms of this
Agreement, will become effective, without notice to the Company or any other
Person, upon the effective date of such change.

         3.4. Quotation of Rates. It is hereby acknowledged that a Responsible
Officer or other appropriately designated officer of the Company may call
Administrative Agent on or before the date on which a Notice of Borrowing is to
be delivered by the Company in order to receive an indication of the rates then
in effect, but such indicated rates shall neither be binding upon Administrative
Agent or Lenders nor affect the rate of interest which thereafter is actually in
effect when the Notice of Borrowing is given.

         3.5 Default Rate. At the option of Determining Lenders and to the
extent permitted by Law, all past-due Principal Debt and accrued interest
thereon shall bear interest from maturity (whether stated or by acceleration) at
the Default Rate until paid, regardless whether such payment is made before or
after entry of a judgment.

         3.6 Interest Recapture. If the designated rate applicable to any
Borrowing exceeds the Maximum Rate, the rate of interest on such Borrowing shall
be limited to the Maximum Rate, but any subsequent reductions in such designated
rate shall not reduce the rate of interest thereon below the Maximum Rate until
the total amount of interest accrued thereon equals the amount of interest which
would have accrued thereon if such designated rate had at all times been in
effect. In the event that at maturity (stated or by acceleration), or at final
payment of the Principal Debt, the total amount of interest paid or accrued is
less than the amount of interest which would have accrued if such designated
rates had at all times been in effect, then, at such time and to the extent
permitted by Law, the Company shall pay an amount equal to the difference, if
any, by which (a) the lesser of the amount of interest which would have accrued
if such designated rates had at all times been in effect and the amount of
interest which would have accrued if the Maximum Rate had at all times been in
effect, exceeds (b) the amount of interest actually paid or accrued on the
Principal Debt.

         3.7 Interest Calculations.

                  (a) All payments of interest shall be calculated on the basis
         of actual number of days (including the first day but excluding the
         last day) elapsed but computed as if each calendar year consisted of
         (i) 360 days in the case of a Eurodollar Rate Borrowing or a Base Rate
         Borrowing calculated with reference to the Federal Funds Rate (unless
         such calculation would result in the interest on the Borrowings
         exceeding the Maximum Rate in which event such interest shall be
         calculated on the basis of a year of 365 or 366 days, as the case may
         be) and (ii) 365 or 366 days, as the case may be, in the case of a Base
         Rate Borrowing calculated with reference to the Prime Rate. All
         interest rate determinations and calculations by Administrative Agent
         shall be conclusive and binding absent manifest error.

                  (b) The provisions of this Agreement relating to calculation
         of the Base Rate and the Adjusted Eurodollar Rate are included only for
         the purpose of determining the rate of interest or other amounts to be
         paid hereunder that are based upon such rate.

                                      29              FIRST AMENDED AND RESTATED
                                                             TERM LOAN AGREEMENT

<PAGE>

         3.8 Maximum Rate. Regardless of any provision contained in any Loan
Paper, no Lender shall ever be entitled to contract for, charge, take, reserve,
receive, or apply, as interest on the Obligation, or any part thereof, any
amount in excess of the Maximum Rate, and, if a Lender ever does so, then such
excess shall be deemed a partial prepayment of principal and treated hereunder
as such and any remaining excess shall be refunded to the Company. In
determining if the interest paid or payable exceeds the Maximum Rate, the
Company and Lenders shall, to the maximum extent permitted under applicable Law,
(a) treat all Borrowings as but a single extension of credit (and Lenders and
the Company agree that such is the case and that provision herein for multiple
Borrowings is for convenience only), (b) characterize any nonprincipal payment
otherwise payable under the Loan Papers as an expense, fee, or premium, rather
than as interest, (c) exclude voluntary prepayments and the effects thereof, and
(d) amortize, prorate, allocate, and spread the total amount of interest
throughout the entire contemplated term of the Obligation; provided that, if the
Obligation is paid and performed in full prior to the end of the full
contemplated term thereof, and if the interest received for the actual period of
existence thereof exceeds the Maximum Amount, Lenders shall refund such excess,
and, in such event, Lenders shall not, to the extent permitted by Law, be
subject to any penalties provided by any Laws for contracting for, charging,
taking, reserving, or receiving interest in excess of the Maximum Amount.

         3.9 Interest Periods. When the Company requests any Eurodollar Rate
Borrowing, the Company may elect the interest period (each an "INTEREST PERIOD")
applicable thereto, which shall be, at the Company's option, in respect of any
Eurodollar Rate Borrowing, one, two, three, or six months; provided, however,
that: (a) the initial Interest Period for a Eurodollar Rate Borrowing shall
commence on the date of such Borrowing (including the date of any conversion
thereto), and each Interest Period occurring thereafter in respect of such
Borrowing shall commence on the day on which the next preceding Interest Period
applicable thereto expires; (b) if any Interest Period for a Eurodollar Rate
Borrowing begins on a day for which there is no numerically corresponding
Business Day in the calendar month at the end of such Interest Period, such
Interest Period shall end on the next Business Day immediately following what
otherwise would have been such numerically corresponding day in the calendar
month at the end of such Interest Period (unless such date would be in a
different calendar month from what would have been the month at the end of such
Interest Period, or unless there is no numerically corresponding day in the
calendar month at the end of the Interest Period; whereupon, such Interest
Period shall end on the last Business Day in the calendar month at the end of
such Interest Period); (c) no Interest Period may be chosen with respect to any
portion of the Principal Debt which would extend beyond the scheduled repayment
date (including any dates on which mandatory prepayments are required to be
made) for such portion of the Principal Debt; and (d) no more than an aggregate
of six (6) Interest Periods shall be in effect at one time.

         3.10 Conversions. The Company may (a) convert a Eurodollar Rate
Borrowing on the last day of an Interest Period to a Base Rate Borrowing, (b)
convert a Base Rate Borrowing at any time to a Eurodollar Rate Borrowing, and
(c) elect a new Interest Period (in the case of a Eurodollar Rate Borrowing), by
giving notice (a "NOTICE OF CONVERSION," substantially in the form of EXHIBIT B)
of such intent no later than 11:00 a.m. New York, New York, time on the third
Business Day prior to the date of conversion or the last day of the Interest
Period, as the case may be (in the case of a conversion to a Eurodollar Rate
Borrowing or an election of a new Interest Period), and no later than 11:00 a.m.
New York, New York time one Business Day prior to the last day of the Interest
Period (in the case of a conversion to a Base Rate Borrowing); provided that the
principal amount converted to, or continued as, a Eurodollar Rate Borrowing
shall be in an amount not less than $5,000,000 or a greater integral multiple of
$1,000,000. Administrative Agent shall timely notify each Lender with respect to
each Notice of Conversion. Absent the Company's Notice of Conversion or election
of a new Interest Period, a Eurodollar Rate Borrowing shall be deemed converted
to a Base Rate Borrowing effective as of the expiration of the Interest Period
applicable thereto. No Eurodollar Rate Borrowing may be continued as a
Eurodollar Rate Borrowing, and no Base Rate Borrowing may be converted to a
Eurodollar Rate Borrowing, if (i) a Default has occurred and is continuing, or
(ii) the interest rate for such Eurodollar Rate Borrowing would exceed the
Maximum Rate.

         3.11 Order of Application.

                  (a) So long as no Default or Potential Default has occurred
         and is continuing, payments and prepayments of the Obligation shall be
         applied in the order and manner as the Company may direct; provided
         that, each such payment or prepayment (other than payments of fees
         payable solely to any Agent or a specific Lender) shall be allocated
         among Lenders in proportion to their respective Pro Rata Parts
         appropriate for the Term Facility in respect of which such payments
         were made.

                  (b) If a Default or Potential Default has occurred and is
         continuing (or if the Company fails to give directions as permitted
         under SECTION 3.11(a)), any payment or prepayment (including proceeds
         from the exercise of any Rights) shall be applied in the following
         order: (i) to the ratable payment of all fees and expenses for which
         Agents or Lenders have not been paid or reimbursed in accordance with
         the Loan Papers (as used in this SECTION 3.11(b), a "ratable payment"
         for any Lender or Agents shall be, on any date of determination, that
         proportion which the portion of the total fees and indemnities owed to
         such Lender or Agents bears to the total aggregate fees and indemnities
         owed to all Lenders or Agents on such date of determination); (ii) to
         the Pro Rata payment of all accrued and unpaid interest on the
         Principal Debt; (iii) to the Pro Rata payment of the remaining
         Principal Debt in such order as Determining Lenders may elect (provided
         that, Determining Lenders will apply such proceeds in an order that
         will minimize any Consequential Loss); and (vii) to the payment of the
         remaining Obligation in the order and manner Determining Lenders deem
         appropriate.

         3.12 Sharing of Payments, Etc.. If any Lender shall obtain any payment
(whether voluntary, involuntary, or otherwise, including, without limitation, as
a result of exercising its Rights under SECTION 3.13) which is in excess of its
ratable share of any such payment, such Lender shall purchase from the other
Lenders such participations as shall be necessary to cause such purchasing
Lender to share the excess payment ratably with each of them; provided, however,
that if all or any portion of such excess payment is thereafter recovered from
such purchasing Lender, the purchase shall be rescinded and the purchase price
restored to the extent of such recovery. The Company agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section may to
the fullest extent permitted by Law, exercise all of its Rights of payment
(including the Right of offset) with respect to such participation as fully as
if such Lender were the direct creditor of the Company in the amount of such
participation.

         3.13 Offset. Upon the occurrence and during the continuance of a
Default, each Lender shall be entitled to exercise (for the benefit of all
Lenders in accordance with SECTION 3.12) the Rights of offset and/or banker's
Lien against each and every account and other property, or any interest therein,
which the Company may now or hereafter have with, or which is now or hereafter
in the possession of, such Lender to the extent of the full amount of the
Obligation owed to such Lender.

         3.14 Booking Borrowings. To the extent permitted by Law, any Lender may
make, carry, or transfer its Borrowings at, to, or for the account of any of its
branch offices or the office of any of its Affiliates; provided that no
Affiliate shall be entitled to receive any greater payment under SECTION 4 than
the transferor Lender would have been entitled to receive with respect to such
Borrowings.

SECTION 4  CHANGE IN CIRCUMSTANCES.

         4.1 Increased Cost and Reduced Return.

                  (a) If, after the date hereof, the adoption of any applicable
         law, rule, or regulation or any change in any applicable law, rule, or
         regulation, or any change in the interpretation or administration

                                      31              FIRST AMENDED AND RESTATED

         thereof by any Governmental Authority, or compliance by any Lender (or
         its Applicable Lending Office) with any request or directive (whether
         or not having the force of law) of any such Governmental Authority:

                           (i) shall subject such Lender (or its Applicable
                  Lending Office) to any Tax or other charge with respect to any
                  Eurodollar Rate Borrowing, its Notes, or its obligation to
                  loan Eurodollar Rate Borrowings, or change the basis of
                  taxation of any amounts payable to such Lender (or its
                  Applicable Lending Office) under this Agreement or its Notes
                  in respect of any Eurodollar Rate Borrowings (other than with
                  respect to taxes imposed on the taxable net income of such
                  Lender by any jurisdiction within which such Lender is
                  incorporated or organized or has its principal office, or
                  within which such Applicable Lending Office is located, or by
                  any other jurisdiction in which such Lender is deemed to be
                  doing business);

                           (ii) shall impose, modify, or deem applicable any
                  reserve, special deposit, assessment, or similar requirement
                  (other than the Reserve Requirement utilized in the
                  determination of the Adjusted Eurodollar Rate) relating to any
                  extensions of credit or other assets of, or any deposits with
                  or other liabilities or commitments of, such Lender (or its
                  Applicable Lending Office), including the commitment of such
                  Lender hereunder; or

                           (iii) shall impose on such Lender (or its Applicable
                  Lending Office) or the London interbank market any other
                  condition affecting this Agreement or its Notes or any of such
                  extensions of credit or liabilities or commitments;

         and the result of any of the foregoing is to increase the cost to such
         Lender (or its Applicable Lending Office) of making, converting into,
         continuing, or maintaining any Eurodollar Rate Borrowings or to reduce
         any sum received or receivable by such Lender (or its Applicable
         Lending Office) under this Agreement or its Notes with respect to any
         Eurodollar Rate Borrowing, then the Company shall pay to such Lender on
         demand such amount or amounts as will compensate such Lender for such
         increased cost or reduction as provided in SECTION 4.1(c) below. If any
         Lender requests compensation by the Company under this SECTION 4.1(a),
         the Company may, by notice to such Lender (with a copy to
         Administrative Agent), suspend the obligation of such Lender to loan or
         continue Borrowings of the Type with respect to which such compensation
         is requested, or to convert Borrowings of any other Type into
         Borrowings of such Type, until the event or condition giving rise to
         such request ceases to be in effect (in which case the provisions of
         SECTION 4.4 shall be applicable); provided, that such suspension shall
         not affect the right of such Lender to receive the compensation so
         requested.

                  (b) If, after the date hereof, any Lender shall have
         determined that the adoption of any applicable Law regarding capital
         adequacy or any change therein or in the interpretation or
         administration thereof by any Governmental Authority charged with the
         interpretation or administration thereof, or any request or directive
         regarding capital adequacy (whether or not having the force of law) of
         any such Governmental Authority has or would have the effect of
         reducing the rate of return on the capital of such Lender or any
         corporation controlling such Lender as a consequence of such Lender's
         obligations hereunder to a level below that which such Lender or such
         corporation could have achieved but for such adoption, change, request,
         or directive (taking into consideration its policies with respect to
         capital adequacy), then from time to time upon demand the Company shall
         pay to such Lender such additional amount or amounts as will compensate
         such Lender for such reduction; provided, however, that the Company
         shall not be obligated to pay any such additional amount or amounts
         incurred or accruing more than ninety (90) days prior to the date on
         which the affected Lender gives written notice thereof in accordance
         with SECTION 4.1(c) below.

                                      32              FIRST AMENDED AND RESTATED
                                                             TERM LOAN AGREEMENT
<PAGE>

                  (c) Each Lender shall promptly notify the Company and
         Administrative Agent of any event of which it has knowledge, occurring
         after the date hereof, which will entitle such Lender to compensation
         pursuant to this Section and will designate a different Applicable
         Lending Office if such designation will avoid the need for, or reduce
         the amount of, such compensation and will not, in the judgment of such
         Lender, be otherwise disadvantageous to it. Any Lender claiming
         compensation under this Section shall furnish to the Company and
         Administrative Agent a statement setting forth in reasonable detail the
         additional amount or amounts to be paid hereunder which shall be
         presumed correct in the absence of manifest error. In determining such
         amount, such Lender may use any reasonable averaging and attribution
         methods.

         4.2 Limitation on Types of Loans. If on or prior to the first day of
any Interest Period for any Eurodollar Rate Borrowing:

                  (a) Administrative Agent determines (which determination shall
         be conclusive) that by reason of circumstances affecting the relevant
         market, adequate and reasonable means do not exist for ascertaining the
         Eurodollar Rate for such Interest Period; or

                  (b) Determining Lenders determine (which determination shall
         be conclusive) and notify Administrative Agent that the Adjusted
         Eurodollar Rate will not adequately and fairly reflect the cost to the
         Lenders of funding Eurodollar Rate Borrowings for such Interest Period;

then Administrative Agent shall give the Company prompt notice thereof
specifying the relevant amounts or periods, and so long as such condition
remains in effect, the Lenders shall be under no obligation to fund additional
Eurodollar Rate Borrowings, continue Eurodollar Rate Borrowings, or to convert
Base Rate Borrowings into Eurodollar Rate Borrowings, and the Company shall, on
the last day(s) of the then current Interest Period(s) for the outstanding
Eurodollar Rate Borrowings, either prepay such Borrowings or convert such
Borrowings into Base Rate Borrowings in accordance with the terms of this
Agreement.

         4.3 Illegality. Notwithstanding any other provision of this Agreement,
in the event that it becomes unlawful for any Lender or its Applicable Lending
Office to make, maintain, or fund Eurodollar Rate Borrowings hereunder, then
such Lender shall promptly notify the Company thereof and such Lender's
obligation to make or continue Eurodollar Rate Borrowings and to convert other
Base Rate Borrowings into Eurodollar Rate Borrowings shall be suspended until
such time as such Lender may again make, maintain, and fund Eurodollar Rate
Borrowings (in which case the provisions of SECTION 4.4 shall be applicable).

         4.4 Treatment of Affected Loans. If the obligation of any Lender to
fund Eurodollar Rate Borrowings or to continue, or to convert Base Rate
Borrowings into Eurodollar Rate Borrowings, shall be suspended pursuant to
SECTIONS 4.1, 4.2, or 4.3 hereof, such Lender's Eurodollar Rate Borrowings shall
be automatically converted into Base Rate Borrowings on the last day(s) of the
then current Interest Period(s) for Eurodollar Rate Borrowings (or, in the case
of a conversion required by SECTION 4.3 hereof, on such earlier date as such
Lender may specify to the Company with a copy to Administrative Agent) and,
unless and until such Lender gives notice as provided below that the
circumstances specified in SECTIONS 4.1, 4.2, or 4.3 hereof that gave rise to
such conversion no longer exist:

                  (a) to the extent that such Lender's Eurodollar Rate
         Borrowings have been so converted, all payments and prepayments of
         principal that would otherwise be applied to such Lender's Eurodollar
         Rate Borrowings shall be applied instead to its Base Rate Borrowings;
         and

                  (b) all Borrowings that would otherwise be made or continued
         by such Lender as Eurodollar Rate Borrowings shall be made or continued
         instead as Base Rate Borrowings, and all

                                      33              FIRST AMENDED AND RESTATED
                                                             TERM LOAN AGREEMENT

<PAGE>

         Borrowings of such Lender that would otherwise be converted into
         Eurodollar Rate Borrowings shall be converted instead into (or shall
         remain as) Base Rate Borrowings.

If such Lender gives notice to the Company (with a copy to Administrative Agent)
that the circumstances specified in SECTIONS 4.1, 4.2, or 4.3 hereof that gave
rise to the conversion of such Lender's Eurodollar Rate Borrowings pursuant to
this SECTION 4.4 no longer exist (which such Lender agrees to do promptly upon
such circumstances ceasing to exist) at a time when Eurodollar Rate Borrowings
made by other Lenders are outstanding, such Lender's Base Rate Borrowings shall
be automatically converted, on the first day(s) of the next succeeding Interest
Period(s) for such outstanding Eurodollar Rate Borrowings, to the extent
necessary so that, after giving effect thereto, all Eurodollar Rate Borrowings
held by the Lenders and by such Lender are held Pro Rata (as to principal
amounts, Types, and Interest Periods).

         4.5 Compensation; Replacement of Lenders.

                  (a) Upon the request of any Lender, the Company shall pay to
         such Lender such amount or amounts as shall be sufficient (in the
         reasonable opinion of such Lender) to compensate it for any
         Consequential Loss; provided that, in each case, the Person claiming
         such Consequential Loss has furnished the Company with a reasonably
         detailed statement of such loss, which statement shall be conclusive in
         the absence of manifest error.

                  (b) If any Lender requests compensation under SECTIONS 4.1 or
         if the Company is required to pay additional amounts to or for the
         account of any Lender pursuant to SECTION 4.6 (collectively,
         "ADDITIONAL AMOUNTS"), then the Company may, at its sole expense and
         effort, upon written notice to such Lender and Administrative Agent,
         require such Lender to assign and delegate, without recourse, all its
         interests, Rights, and obligations under this Agreement and the other
         Loan Papers to an Eligible Assignee that shall assume such obligations;
         provided that, (i) the Company shall have received the prior written
         consent of Administrative Agent to any such assignment; (ii) such
         Lender shall have received payment from the Company of any Additional
         Amounts owed to such Lender by the Company for periods prior to the
         replacement of such Lender and any costs incurred as a result of such
         replacement of a Lender; (iii) such assignment will result in reduction
         or elimination of the Additional Amounts; and (iv) such assignment and
         acceptance shall be made in accordance with, and subject to the
         requirements and restrictions contained in, SECTION 12.13(b), other
         than the restrictions imposed by SECTION 12.13(b)(iv). A Lender shall
         not be required to make any such assignment and delegation if, prior
         thereto, as a result of a waiver by such Lender or otherwise, the
         circumstances entitling such Borrowing to require such assignment and
         delegation cease to apply.

         4.6 Taxes.

                  (a) Any and all payments by the Company to or for the account
         of any Lender or Administrative Agent hereunder or under any other Loan
         Paper shall be made free and clear of and without deduction for any and
         all present or future Taxes, excluding, in the case of each Lender and
         Administrative Agent, Taxes imposed on its income and franchise Taxes
         imposed on it by any jurisdiction within which such Lender (or its
         Applicable Lending Office) or Administrative Agent (as the case may be)
         is incorporated or organized, or any political subdivision thereof, or
         by any other jurisdiction in which such Lender or Administrative Agent,
         as the case may be, is deemed to be doing business under the Tax Laws
         thereof (all such Non-Excluded Taxes referred to as "NON-EXCLUDED
         TAXES"). If the Company shall be required by law to deduct any
         Non-Excluded Taxes from or in respect of any sum payable under this
         Agreement or any other Loan Paper to any Lender or Administrative
         Agent, (i) the sum payable shall be increased as necessary so that
         after making all required deductions (including deductions applicable
         to additional sums payable under this

                                      34              FIRST AMENDED AND RESTATED

<PAGE>

         SECTION 4.6) such Lender or Administrative Agent receives an amount
         equal to the sum it would have received had no such deductions been
         made, (ii) the Company shall make such deductions, (iii) the Company
         shall pay the full amount deducted to the relevant taxation authority
         or other authority in accordance with applicable law, and (iv) within
         thirty (30) days after the date of any payment of Non-Excluded Taxes,
         the Company shall furnish to Administrative Agent, at its address
         listed in SCHEDULE 2.1, the original or a certified copy of a receipt
         evidencing payment thereof.

                  (b) In addition, the Company agrees to pay any and all present
         or future stamp or documentary taxes or charges or similar levies which
         arise from any payment made under this Agreement or any other Loan
         Paper or from the execution or delivery of, or otherwise with respect
         to, this Agreement or any other Loan Paper (hereinafter referred to as
         "OTHER TAXES").

                  (c) THE COMPANY AGREES TO INDEMNIFY EACH LENDER AND
         ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF NON-EXCLUDED TAXES THAT
         SHOULD HAVE BEEN WITHHELD BY THE COMPANY AND OTHER TAXES (INCLUDING,
         WITHOUT LIMITATION, ANY NON-EXCLUDED TAXES THAT SHOULD HAVE BEEN
         WITHHELD BY THE COMPANY OR OTHER TAXES IMPOSED OR ASSERTED BY ANY
         JURISDICTION ON AMOUNTS PAYABLE UNDER THIS SECTION 4.6) PAID BY SUCH
         LENDER OR ADMINISTRATIVE AGENT (AS THE CASE MAY BE) AND ANY LIABILITY
         (INCLUDING PENALTIES, INTEREST, AND EXPENSES) ARISING THEREFROM OR WITH
         RESPECT THERETO.

                  (d) Each Lender organized under the laws of a jurisdiction
         outside the United States, on or prior to the date of its execution and
         delivery of this Agreement in the case of each Lender listed on the
         signature pages hereof and on or prior to the date on which it becomes
         a Lender in the case of each other Lender, and from time to time
         thereafter if requested in writing by the Company or Administrative
         Agent (but only so long as such Lender remains lawfully able to do so),
         shall provide the Company and Administrative Agent with (i) two duly
         completed, accurate, and signed copies of Internal Revenue Service Form
         1001 or 4224, as appropriate, or any successor form prescribed by the
         Internal Revenue Service, certifying that such Lender is entitled to
         benefits under an income tax treaty to which the United States is a
         party which reduces the rate of withholding tax on payments of interest
         or certifying that the income receivable pursuant to this Agreement is
         effectively connected with the conduct of a trade or business in the
         United States, (ii) a duly completed, accurate and signed Internal
         Revenue Service Form W-8 or W-9, as appropriate, or any successor form
         prescribed by the Internal Revenue Service, and (iii) any other form or
         certificate required by any taxing authority (including any certificate
         required by Sections 871(h) and 881(c) of the Internal Revenue Code),
         certifying that such Lender is entitled to an exemption from or a
         reduced rate of tax on payments pursuant to this Agreement or any of
         the other Loan Papers.

                  (e) For any period with respect to which a Lender has failed
         to provide the Company and Administrative Agent with the appropriate
         form pursuant to SECTION 4.6(d) (unless such failure is due to a change
         in Law, other than any change in the nature of an anti-treaty shopping
         or limitation on benefits or similar provision, occurring subsequent to
         the date on which a form originally was required to be provided), such
         Lender shall not be entitled to indemnification under SECTION 4.6(a) or
         4.6(b) with respect to Taxes imposed by the United States; provided,
         however, that should a Lender, which is otherwise exempt from or
         subject to a reduced rate of withholding tax, become subject to Taxes
         because of its failure to deliver a form required hereunder, the
         Company shall take such steps as such Lender shall reasonably request
         to assist such Lender to recover such Taxes.

                  (f) If the Company is required to pay additional amounts to or
         for the account of any Lender pursuant to this SECTION 4.6, then such
         Lender will agree to use reasonable efforts to change

                                      35              FIRST AMENDED AND RESTATED

         the jurisdiction of its Applicable Lending Office so as to eliminate or
         reduce any such additional payment which may thereafter accrue if such
         change, in the judgment of such Lender, is not otherwise
         disadvantageous to such Lender.

                  (g) Without prejudice to the survival of any other agreement
         of the Company hereunder, the agreements and obligations of the Company
         contained in this SECTION 4.6 shall survive the payment in full of the
         Notes.

SECTION 5  FEES

         5.1 Treatment of Fees. Except as otherwise provided by Law, the fees
described in this SECTION 5: (a) do not constitute compensation for the use,
detention, or forbearance of money, (b) are in addition to, and not in lieu of,
interest and expenses otherwise described in this Agreement, (c) shall be
payable in accordance with SECTION 3.1, (d) shall be non-refundable, (e) shall,
to the fullest extent permitted by Law, bear interest, if not paid when due, at
the Default Rate, and (f) shall be calculated on the basis of actual number of
days (including the first day but excluding the last day) elapsed, but computed
as if each calendar year consisted of 360 days.

         5.2 Fees of Administrative Agent and Arranger. The Company shall pay to
Administrative Agent or Arranger, as the case may be, solely for their

                  prepayment, commitment reduction or cash collateralization of

                  aggregate amount not to exceed $65,000,000 per annum; and

         (5)      the Company may prepay, defease or otherwise satisfy in whole
                  or in part all of its obligations arising under the Letter of
                  Credit and Reimbursement Agreement dated as of May 15, 1994,
                  among Tulsa Parking Authority, the Company, Bank of Oklahoma,
                  National Association, and Bank of America, N.A. (formerly

                  documents, instruments, agreements, certificates and notices
                  at any time executed and/or delivered in connection therewith.

         For the avoidance of doubt, nothing in this SECTION 8.24 shall limit or
restrict the Company from any payment or taking any action that is required by
the terms of any Progeny Facility or Legacy L/Cs in effect on the date hereof.

SECTION  9   DEFAULT.  The term "DEFAULT" means the occurrence and continuance

and payable, or (iii) shall fail to pay any other part of the Obligation

the Loan Papers).

         9.2 Misrepresentation. Any representation or warranty made by the
Company or any Guarantor (or any of their respective officers) in writing under

         9.3 Covenants. The Company or any Guarantor shall fail to perform or
observe (i) any term, covenant or agreement contained in SECTION 8.2 on its part

to the Company by the Administrative Agent or any Lender or the date the Company
shall have knowledge of such failure, (ii) any term, covenant or agreement
contained in this Agreement (other than a term, covenant or agreement contained
in SECTION 8.2 or SECTIONS 8.5 - 8.24) or any Note or any other Loan Paper on
its part to be performed or observed; and such failure shall continue for five
(5) Business Days after the earlier of the date notice thereof shall have been
given to the Company by the Administrative Agent or any Lender or the date the
Company or such Guarantor, as applicable shall have knowledge of such failure;
or (iii) any term, covenant or agreement contained in SECTION 8.5 - 8.24.

the Company or such Subsidiary (as the case may be), when the same becomes due
and payable (whether by scheduled maturity, required prepayment, acceleration,
demand or otherwise), and such failure shall continue after the applicable grace
period, if any, specified in the agreement or

                                      49              FIRST AMENDED AND RESTATED

<PAGE>

instrument relating to such Debt; or any other event shall occur or condition
shall exist under any agreement or instrument relating to any such Debt and
shall continue after the applicable grace period, if any, specified in such
agreement or instrument, if the effect of such event or condition is to
accelerate, or to permit the acceleration of, the maturity of such Debt; or any
such Debt shall be declared to be due and payable, or required to be prepaid
(other than (i) by a regularly scheduled required prepayment, (ii) as required
in connection with any permitted sale of assets, (iii) as required in connection
with any casualty or condemnation, or (iv) or as a result of the giving of
notice of a voluntary prepayment), prior to the stated maturity thereof;
provided, however, that the provisions of this SECTION 9.4 shall not apply to
any Non-Recourse Debt of any Non-Borrowing Subsidiary (as defined in the Primary
Credit Agreement) of the Company.

         9.5 Debtor Relief. The Company or any of its Material Subsidiaries
shall generally not pay its debts as such debts become due, or shall admit in

adjudicate it as bankrupt or insolvent, or seeking liquidation, winding up,
reorganization, arrangement, adjustment, protection, relief, or composition of
it or its debts under any law relating to bankruptcy, insolvency or
reorganization or relief of debtors, or seeking the entry of an order for relief

instituted against it (but not instituted by it), shall remain undismissed or
unstayed for a period of sixty (60) days; or the Company or any of its Material
Subsidiaries shall take any action to authorize any of the actions set forth
above in this SECTION 9.5.

         9.6 Judgments. Any judgment or order for the payment of money in excess

         of a Plan with respect to which a Termination Event described in CLAUSE
         (b) of the definition of Termination Event shall have occurred and then
         exist, the liability related thereto) is equal to or greater than

         when aggregated with all other amounts required to be paid to
         Multiemployer Plans in connection with Withdrawal Liabilities
         (determined as of the date of such notification), exceeds $75,000,000
         or requires payments exceeding $50,000,000 per annum; or

                  (c) The Company or any ERISA Affiliate shall have been

         the aggregate annual contributions of the Company and its ERISA
         Affiliates to all Multiemployer Plans which are then in reorganization
         or being terminated have been or will be increased over the amounts
         contributed

         9.8 Validity and Enforceability of Loan Papers. Any provision (other
than any provision excepted from, or subject to a qualification in, the opinions
delivered pursuant to Item 9 of Schedule 6.1, but only to the extent of such
exception or qualification) of any Loan Paper for any reason shall cease to be a
legal, valid, binding and enforceable obligation of the Company or any Guarantor
party thereto or the Company or any Guarantor party thereto shall so state in
writing.

SECTION 10  RIGHTS AND REMEDIES

         10.1 Remedies Upon Default.

                  (a) If a Default exists under SECTION 9.5, the entire unpaid
         balance of the Obligation under the Term Facility shall automatically
         become due and payable without any action or notice of any kind
         whatsoever.

                  (b) If any Default exists, Administrative Agent may (and,
         subject to the terms of SECTION 11, shall upon the request of
         Determining Lenders) or Determining Lenders may, do any one or more of
         the following: (i) if the maturity of the Obligation under the Term
         Facility has not already been accelerated under SECTION 10.1(a),
         declare the entire unpaid balance of the Obligation, or any part
         thereof, immediately due and payable, whereupon it shall be due and
         payable; (ii) reduce any claim to judgment; (iii) to the extent
         permitted by Law, exercise (or request each Lender to, and each Lender
         shall be entitled to, exercise) the Rights of offset or banker's Lien
         against the interest of the Company in and to every account and other
         property of the Company which are in the possession of Administrative
         Agent or any Lender to the extent of the full amount of the Obligation
         (to the extent permitted by Law, the Company being deemed directly
         obligated to each Lender in the full amount of the Obligation for such
         purposes); and (iv) exercise any and all other legal or equitable
         Rights afforded by the Loan Papers, the Laws of the State of New York,
         or any other applicable jurisdiction as Administrative Agent shall deem
         appropriate, or otherwise, including, but not limited to, the Right to
         bring suit or other proceedings before any Governmental Authority
         either for specific performance of any covenant or condition contained
         in any of the Loan Papers or in aid of the exercise of any Right
         granted to Administrative Agent or any Lender in any of the Loan
         Papers.

         10.2 The Company Waivers. To the extent permitted by Law, the Company
hereby waives presentment and demand for payment, protest, notice of intention
to accelerate, notice of acceleration, and notice of protest and nonpayment, and
agrees that its liability with respect to the Obligation (or any part thereof),
shall not be affected by any renewal or extension in the time of payment of the
Obligation (or any part thereof), by any indulgence, or by any release or change
in any security for the payment of the Obligation (or any part thereof).

         10.3 Performance by Administrative Agent. If any covenant, duty, or
agreement of the Company is not performed in accordance with the terms of the
Loan Papers, after the occurrence and during the continuance of a Default,
Administrative Agent may, at its option (but subject to the approval of
Determining Lenders), perform or attempt to perform such covenant, duty, or
agreement on behalf of the Company. In such event, any amount expended by
Administrative Agent in such performance or attempted performance shall be
payable by the Company, to Administrative Agent on demand, shall become part of
the Obligation, and shall bear interest at the Default Rate from the date of
such expenditure by Administrative Agent until paid. Notwithstanding the
foregoing, it is expressly understood that Administrative Agent does not assume
and shall

                                      51              FIRST AMENDED AND RESTATED
                                                             TERM LOAN AGREEMENT

<PAGE>

never have, except by its express written consent, any liability or
responsibility for the performance of any covenant, duty, or agreement of the
Company.

         10.4 Delegation of Duties and Rights. Lenders may perform any of their
duties or exercise any of their Rights under the Loan Papers by or through their
respective Representatives (provided, that such delegation does not release any
Lender of any of its obligations hereunder).

         10.5 Not in Control. Nothing in any Loan Paper shall, or shall be
deemed to (a) give any Agent or any Lender the Right to exercise control over
the assets (including real property), affairs, or management of the Company, (b)
preclude or interfere with compliance by the Company with any Law, or (c)
require any act or omission by the Company that may be harmful to Persons or
property. Any "material adverse event" or other materiality qualifier in any
representation, warranty, covenant, or other provision of any Loan Paper is
included for credit documentation purposes only and shall not, and shall not be
deemed to, mean that any Agent or any Lender acquiesces in any non-compliance by
the Company with any Law or document, or that any Agent or any Lender does not
expect the Company to promptly, diligently, and continuously carry out all
appropriate removal, remediation, and termination activities required or
appropriate in accordance with all Environmental Protection Statutes. No Agent
or Lender has any fiduciary relationship with or fiduciary duty to the Company
arising out of or in connection with the Loan Papers, and the relationship
between Agents and Lenders, on the one hand, and the Company, on the other hand,
in connection with the Loan Papers is solely that of debtor and creditor. The
power of Agents and Lenders under the Loan Papers is limited to the Rights
provided in the Loan Papers, which Rights exist solely to assure payment and
performance of the Obligation and may be exercised in a manner calculated by
Agents and Lenders in their respective good faith business judgment.

         10.6 Course of Dealing. The acceptance by Administrative Agent or
Lenders at any time and from time to time of partial payment on the Obligation
shall not be deemed to be a waiver of any Default then existing. No waiver by
Administrative Agent, Determining Lenders, or Lenders of any Default shall be
deemed to be a waiver of any other then-existing or subsequent Default. No delay
or omission by Administrative Agent, Determining Lenders, or Lenders in
exercising any Right under the Loan Papers shall impair such Right or be
construed as a waiver thereof or any acquiescence therein, nor shall any single
or partial exercise of any such Right preclude other or further exercise
thereof, or the exercise of any other Right under the Loan Papers or otherwise.

         10.7 Cumulative Rights. All Rights available to Administrative Agent
and Lenders under the Loan Papers are cumulative of and in addition to all other
Rights granted to Administrative Agent and Lenders at law or in equity, whether
or not the Obligation is due and payable and whether or not Administrative Agent
or Lenders have instituted any suit for collection, foreclosure, or other action
in connection with the Loan Papers.

         10.8 Application of Proceeds. Any and all proceeds ever received by
Administrative Agent or Lenders from the exercise of any Rights pertaining to
the Obligation shall be applied to the Obligation in the order and manner set
forth in SECTION 3.11.

         10.9 Limitation of Rights. Notwithstanding any other provision of this
Agreement or any other Loan Paper, any action taken or proposed to be taken by
Administrative Agent or any Lender under any Loan Paper which would affect the
operational, voting, or other control of the Company, shall be pursuant to any
applicable state Law, and the applicable rules and regulations thereunder.

         10.10 Expenditures by Lenders. The Company shall promptly pay within
thirty (30) days after request therefor (a) all reasonable costs, fees, and
expenses paid or incurred by any Agent incident to any Loan

                                      52              FIRST AMENDED AND RESTATED

Paper (including, but not limited to, the reasonable fees and expenses of
counsel to Administrative Agent and the allocated cost of internal counsel in
connection with the negotiation, preparation, delivery, execution, coordination,
and administration of the Loan Papers and any related amendment, waiver, or
consent) and (b) following the occurrence and continuation of a Default, all
reasonable costs and expenses of Lenders and Administrative Agent incurred by
Administrative Agent or any Lender in connection with the enforcement of the
obligations of the Company arising under the Loan Papers (including, without
limitation, costs and expenses incurred in connection with any workout or
bankruptcy) or the exercise of any Rights arising under the Loan Papers
(including, but not limited to, reasonable attorneys' fees including allocated
cost of internal counsel, court costs and other costs of collection), all of
which shall be a part of the Obligation and shall bear interest at the Default
Rate from the date due until the date repaid by the Company.

         10.11 INDEMNIFICATION. THE COMPANY AGREES TO INDEMNIFY AND HOLD
HARMLESS EACH AGENT, ARRANGER, AND EACH LENDER AND EACH OF THEIR RESPECTIVE
AFFILIATES AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS,
ATTORNEYS, AND ADVISORS (EACH, AN "INDEMNIFIED PARTY") FROM AND AGAINST ANY AND
ALL CLAIMS, DAMAGES, ACTUAL LOSSES, LIABILITIES, COSTS, AND EXPENSES (INCLUDING,
WITHOUT LIMITATION, REASONABLE ATTORNEYS' FEES) (BUT SPECIFICALLY EXCLUDING
TAXES), THAT MAY BE INCURRED BY OR ASSERTED OR AWARDED AGAINST ANY INDEMNIFIED
PARTY, IN EACH CASE ARISING OUT OF OR IN CONNECTION WITH OR BY REASON OF
(INCLUDING, WITHOUT LIMITATION, IN CONNECTION WITH ANY INVESTIGATION,
LITIGATION, OR PROCEEDING OR PREPARATION OF DEFENSE IN CONNECTION THEREWITH) THE
LOAN PAPERS, ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THE ACTUAL OR
PROPOSED USE OF THE PROCEEDS OF THE BORROWINGS (INCLUDING ANY OF THE FOREGOING
ARISING FROM THE NEGLIGENCE OF THE INDEMNIFIED PARTY), EXCEPT TO THE EXTENT SUCH
CLAIM, DAMAGE, LOSS, LIABILITY, COST, OR EXPENSE IS FOUND IN A FINAL,
NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED
FROM SUCH INDEMNIFIED PARTY'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, OR
VIOLATION OF ANY LAW OR REGULATION BY SUCH INDEMNIFIED PARTY; PROVIDED, THAT THE
COMPANY SHALL HAVE NO OBLIGATION HEREUNDER TO ANY AGENT OR ANY LENDER WITH
RESPECT TO INDEMNIFIED LIABILITIES ARISING FROM (i) THE GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT OF ANY AGENT OR ANY SUCH LENDER, (ii) LEGAL PROCEEDINGS
COMMENCED AGAINST ANY AGENT OR ANY SUCH LENDER BY ANY SECURITY HOLDER OR
CREDITOR THEREOF ARISING OUT OF AND BASED UPON RIGHTS AFFORDED ANY SUCH SECURITY
HOLDER OR CREDITOR SOLELY IN ITS CAPACITY AS SUCH, OR (iii) LEGAL PROCEEDINGS
COMMENCED AGAINST ANY AGENT OR ANY SUCH LENDER BY ANY OTHER LENDER OR BY ANY
PARTICIPANT (AS DEFINED IN SECTION 12.13). IN THE CASE OF AN INVESTIGATION,
LITIGATION, OR OTHER PROCEEDING TO WHICH THE INDEMNITY IN THIS SECTION 10.11
APPLIES, EXCEPT AS PROVIDED ABOVE, SUCH INDEMNITY SHALL BE EFFECTIVE WHETHER OR
NOT SUCH INVESTIGATION, LITIGATION, OR PROCEEDING IS BROUGHT BY THE COMPANY, ITS
DIRECTORS, SHAREHOLDERS OR CREDITORS OR AN INDEMNIFIED PARTY OR ANY OTHER PERSON
OR ANY INDEMNIFIED PARTY IS OTHERWISE A PARTY THERETO AND WHETHER OR NOT THE
TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED. THE PARTIES HERETO AGREE NOT
TO ASSERT ANY CLAIM AGAINST ANY PARTY ON ANY THEORY OF LIABILITY, FOR SPECIAL,
INDIRECT, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR OTHERWISE
RELATING TO THE LOAN PAPERS, ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN OR THE
ACTUAL OR PROPOSED USE OF THE PROCEEDS OF THE BORROWINGS. WITHOUT PREJUDICE TO
THE SURVIVAL OF ANY OTHER AGREEMENT OF THE COMPANY HEREUNDER, THE AGREEMENTS AND
OBLIGATIONS OF THE COMPANY CONTAINED IN THIS SECTION 10.11 SHALL SURVIVE THE
PAYMENT IN FULL OF THE BORROWINGS AND ALL OTHER AMOUNTS PAYABLE UNDER THIS
AGREEMENT.

SECTION 11  AGREEMENT AMONG LENDERS

         11.1 Administrative Agent.

                                      53              FIRST AMENDED AND RESTATED
                                                             TERM LOAN AGREEMENT
<PAGE>

                  (a) Each Lender hereby appoints Credit Lyonnais New York
         Branch (and Credit Lyonnais New York Branch hereby accepts such
         appointment) as its nominee and agent, in its name and on its behalf:
         (i) to act as nominee for and on behalf of such Lender in and under all
         Loan Papers; (ii) to arrange the means whereby the funds of Lenders are
         to be made available to the Company under the Loan Papers; (iii) to
         take such action as may be requested by any Lender under the Loan
         Papers (when such Lender is entitled to make such request under the
         Loan Papers and after such requesting Lender has obtained the
         concurrence of such other Lenders as may be required under the Loan
         Papers); (iv) to receive all documents and items to be furnished to
         Lenders under the Loan Papers; (v) to be the secured party, mortgagee,
         beneficiary, and similar party in respect of, and to receive, as the
         case may be, any collateral for the benefit of Lenders; (vi) to timely
         distribute, and Administrative Agent agrees to so distribute, to each
         Lender all material information, requests, documents, and items
         received from the Company under the Loan Papers (including written
         disclosures pursuant to SECTION 8.2 (other than pursuant to SECTION
         8.2(d), which shall only be distributed to the requesting Lender),
         SECTION 7.6 and SECTION 7.11); (vii) to promptly distribute to each
         Lender its ratable part of each payment or prepayment (whether
         voluntary, as proceeds of collateral upon or after foreclosure, as
         proceeds of insurance thereon, or otherwise) in accordance with the
         terms of the Loan Papers; (viii) to deliver to the appropriate Persons
         requests, demands, approvals, and consents received from Lenders; and
         (ix) to execute, on behalf of Lenders, such releases or other documents
         or instruments as are permitted by the Loan Papers or as directed by
         Lenders or Determining Lenders (when entitled to so authorize) from
         time to time; provided, however, Administrative Agent shall not be
         required to take any action which exposes Administrative Agent to
         personal liability or which is contrary to the Loan Papers or
         applicable Law.

                  (b) Administrative Agent may resign at any time as
         Administrative Agent under the Loan Papers by giving written notice
         thereof to Lenders. Should the initial or any successor Administrative
         Agent ever cease to be a party hereto or should the initial or any
         successor Administrative Agent ever resign as Administrative Agent,
         then Determining Lenders shall elect the successor Administrative Agent
         from among the Lenders (other than the resigning Administrative Agent).
         If no successor Administrative Agent shall have been so appointed by
         Determining Lenders, within 30 days after the retiring Administrative
         Agent's giving of notice of resignation, then the retiring
         Administrative Agent may, on behalf of Lenders, appoint a successor
         Administrative Agent, which shall be a commercial bank having a
         combined capital and surplus of at least $1,000,000,000. Upon the
         acceptance of any appointment as Administrative Agent under the Loan
         Papers by a successor Administrative Agent, such successor
         Administrative Agent shall thereupon succeed to and become vested with
         all the Rights of the retiring Administrative Agent, and the retiring
         Administrative Agent shall be discharged from its duties and
         obligations of Administrative Agent under the Loan Papers and each
         Lender shall execute such documents as any Lender may reasonably
         request to reflect such change in and under the Loan Papers. After any
         retiring Administrative Agent's resignation as Administrative Agent
         under the Loan Papers, the provisions of this SECTION 11 shall inure to
         its benefit as to any actions taken or omitted to be taken by it while
         it was Administrative Agent under the Loan Papers.

                  (c) Administrative Agent, in its capacity as a Lender, shall
         have the same Rights under the Loan Papers as any other Lender and may
         exercise the same as though it were not acting as Administrative Agent;
         the term "Lender" shall, unless the context otherwise indicates,
         include Administrative Agent; and any resignation of Administrative
         Agent hereunder shall not impair or otherwise affect any Rights which
         it has or may have in its capacity as an individual Lender. Each Lender
         and the Company agree that Administrative Agent is not a fiduciary for
         Lenders or for the Company but simply is acting in the capacity
         described herein to alleviate administrative burdens for both the
         Company and Lenders, that Administrative Agent has no duties or
         responsibilities to Lenders

         or the Company except those expressly set forth herein, and that
         Administrative Agent in its capacity as a Lender has all Rights of any
         other Lender.

                  (d) Administrative Agent and its Affiliates may now or
         hereafter be engaged in one or more loan, letter of credit, leasing, or
         other financing transactions with the Company, act as trustee or
         depositary for the Company, or otherwise be engaged in other
         transactions with the Company (collectively, the "OTHER ACTIVITIES")
         not the subject of the Loan Papers. Without limiting the Rights of
         Lenders specifically set forth in the Loan Papers, Administrative Agent
         and its Affiliates shall not be responsible to account to Lenders for
         such other activities, and no Lender shall have any interest in any
         other activities, any present or future guaranties by or for the
         account of the Company which are not contemplated or included in the
         Loan Papers, any present or future offset exercised by Administrative
         Agent and its Affiliates in respect of such other activities, any
         present or future property taken as security for any such other
         activities, or any property now or hereafter in the possession or
         control of Administrative Agent or its Affiliates which may be or
         become security for the obligations of the Company arising under the
         Loan Papers by reason of the general description of indebtedness
         secured or of property contained in any other agreements, documents or
         instruments related to any such other activities; provided that, if any
         payments in respect of such guaranties or such property or the proceeds
         thereof shall be applied to reduction of the obligations of the Company
         arising under the Loan Papers, then each Lender shall be entitled to
         share in such application ratably. Each Lender acknowledges that, and
         consents to, Credit Lyonnais New York Branch's also serving as
         Administrative Agent under that certain Letter of Credit and
         Reimbursement Agreement of even date herewith among the Company, Credit
         Lyonnais New York Branch, as " Administrative Agent," and certain
         financial institutions party thereto.

         11.2 Expenses. Upon demand by Administrative Agent, each Lender shall
pay its Pro Rata Part of any reasonable expenses (including, without limitation,
court costs, reasonable attorneys' fees and other costs of collection) incurred
by Administrative Agent in connection with any of the Loan Papers if and to the
extent Administrative Agent does not receive reimbursement therefor from other
sources within 60 days after incurred; provided that, each Lender shall be
entitled to receive its Pro Rata Part of any reimbursement for such expenses, or
part thereof, which Administrative Agent subsequently receives from such other
sources.

         11.3 Proportionate Absorption of Losses. Except as otherwise provided
in the Loan Papers, nothing in the Loan Papers shall be deemed to give any
Lender any advantage over any other Lender insofar as the Obligation arising
under the Loan Papers is concerned, or to relieve any Lender from absorbing its
Pro Rata Part of any losses sustained with respect to the Obligation (except to
the extent such losses result from unilateral actions or inactions of any Lender
that are not made in accordance with the terms and provisions of the Loan
Papers).

         11.4 Delegation of Duties; Reliance. Administrative Agent may perform
any of its duties or exercise any of its Rights under the Loan Papers by or
through its Representatives. Administrative Agent and its Representatives shall
(a) be entitled to rely upon (and shall be protected in relying upon) any
writing, resolution, notice, consent, certificate, affidavit, letter, cablegram,
telecopy, telegram, telex or teletype message, statement, order, or other
documents or conversation believed by it or them to be genuine and correct and
to have been signed or made by the proper Person and, with respect to legal
matters, upon opinion of counsel selected by Administrative Agent, (b) be
entitled to deem and treat each Lender as the owner and holder of the Principal
Debt owed to such Lender for all purposes until, subject to SECTION 12.13,
written notice of the assignment or transfer thereof shall have been given to
and received by Administrative Agent (and any request, authorization, consent,
or approval of any Lender shall be conclusive and binding on each subsequent
holder, assignee, or transferee of the Principal Debt owed to such Lender or
portion thereof until such notice is given and received), (c) not be deemed to
have notice of the occurrence of a Default unless a responsible officer of

<PAGE>

Administrative Agent, who handles matters associated with the Loan Papers and
transactions thereunder, has actual knowledge thereof or Administrative Agent
has been notified thereof by a Lender or the Company, and (d) be entitled to
consult with legal counsel (including counsel for the Company), independent
accountants and other experts selected by Administrative Agent and shall not be
liable for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such counsel, accountants or experts.

         11.5 Limitation of Liability.

                  (a) None of the Agents or any of their respective
         Representatives shall be liable for any action taken or omitted to be
         taken by it or them under the Loan Papers in good faith and reasonably
         believed by it or them to be within the discretion or power conferred
         upon it or them by the Loan Papers or be responsible for the
         consequences of any error of judgment, except for fraud, gross
         negligence, or willful misconduct; and none of the Agents, or any of
         their respective Representatives has a fiduciary relationship with any
         Lender by virtue of the Loan Papers (provided that nothing herein shall
         negate the obligation of Administrative Agent to account for funds
         received by it for the account of any Lender).

                  (b) Unless indemnified to its satisfaction against loss, cost,
         liability, and expense, no Agent shall be compelled to do any act under
         the Loan Papers or to take any action toward the execution or
         enforcement of the powers thereby created or to prosecute or defend any
         suit in respect of the Loan Papers. If Administrative Agent requests
         instructions from Lenders or Determining Lenders, as the case may be,
         with respect to any act or action (including, but not limited to, any
         failure to act) in connection with any Loan Paper, such Agent shall be
         entitled (but shall not be required) to refrain (without incurring any
         liability to any Person by so refraining) from such act or action
         unless and until it has received such instructions. In no event,
         however, shall any Agent or any of its respective Representatives be
         required to take any action which it or they determine could incur for
         it or them criminal or onerous civil liability. Without limiting the
         generality of the foregoing, no Lender shall have any right of action
         against any Agent as a result of such Agent's acting or refraining from
         acting hereunder in accordance with the instructions of Determining
         Lenders.

                  (c) No Agent shall be responsible in any manner to any Lender
         or any Participant for, and each Lender represents and warrants that it
         has not relied upon any Agent in respect of, (i) the creditworthiness
         of the Company and the risks involved to such Lender, (ii) the
         effectiveness, enforceability, genuineness, validity, or the due
         execution of any Loan Paper, (iii) any representation, warranty,
         document, certificate, report, or statement made therein or furnished
         thereunder or in connection therewith, (iv) the existence, priority, or
         perfection of any Lien hereafter granted or purported to be granted
         under any Loan Paper, or (v) observation of or compliance with any of
         the terms, covenants, or conditions of any Loan Paper on the part of
         the Company. Each Lender agrees to indemnify Agents and their
         respective Representatives and hold them harmless from and against (but
         limited to such Lender's Pro Rata Part of) any and all liabilities,
         obligations, losses, damages, penalties, actions, judgments, suits,
         costs, reasonable expenses, and reasonable disbursements of any kind or
         nature whatsoever which may be imposed on, asserted against, or
         incurred by them in any way relating to or arising out of the Loan
         Papers or any action taken or omitted by them under the Loan Papers, to
         the extent such Agents and their respective Representatives are not
         reimbursed for such amounts by the Company (provided that, no Agent or
         its Representatives shall have the right to be indemnified hereunder
         for its or their own fraud, gross negligence, or willful misconduct);
         and provided, further, that no Designated Lender shall be liable for
         any payment under this SECTION 11.5(c) so long as, and to the extent
         that, its Designating Lender makes such payments in accordance with,
         and at the time required by, the terms of this Agreement.

<PAGE>

         11.6 Default; Collateral. Upon the occurrence and continuance of a
Default, Lenders agree to promptly confer in order that Determining Lenders or
Lenders, as the case may be, may agree upon a course of action for the
enforcement of the Rights of Lenders; and Administrative Agent shall be entitled
to refrain from taking any action (without incurring any liability to any Person
for so refraining) unless and until Administrative Agent shall have received
instructions from Determining Lenders. In actions with respect to any property
of the Company, Administrative Agent is acting for the ratable benefit of each
Lender. Any and all agreements to subordinate (whether made heretofore or
hereafter) other indebtedness or obligations of the Company to the Obligation
shall be construed as being for the ratable benefit of each Lender. If
Administrative Agent acquires any security for the Obligation or any guaranty of
the Obligation upon or in lieu of foreclosure, the same shall be held for the
Pro Rata benefit of all Lenders.

         11.7 Limitation of Liability. To the extent permitted by Law (a) no
Agent (acting in their respective agent capacities) shall incur any liability to
any other Lender or Participant except for acts or omissions resulting from its
own fraud, gross negligence or wilful misconduct, and (b) no Agent, Lender, or
Participant shall incur any liability to any other Person for any act or
omission of any other Lender, Agent, or Participant.

         11.8 Relationship of Lenders. Nothing herein shall be construed as
creating a partnership or joint venture among Agents and Lenders.

         11.9 Benefits of Agreement. Except for the representations and
covenants in SECTION 11.1(c) in favor of the Company, none of the provisions of
this SECTION 11 shall inure to the benefit of the Company or any other Person
other than Lenders; consequently, neither the Company nor any other Person shall
be entitled to rely upon, or to raise as a defense, in any manner whatsoever,
the failure of any Agent or Lender to comply with such provisions.

         11.10 Agents. None of the Lenders identified in this Agreement as
"SYNDICATION AGENT" or "DOCUMENTATION AGENT" shall have any rights, powers,
obligations, liabilities, responsibilities, or duties under this Agreement other
than those applicable to all Lenders as such. Without limiting the foregoing,
none of the Lenders so identified as a "SYNDICATION AGENT" or "DOCUMENTATION
AGENT" shall have or be deemed to have any fiduciary relationship with any
Lender.

         11.11 Obligation Several. The obligations of Lenders hereunder are
several, and each Lender hereunder shall not be responsible for the obligations
of the other Lenders hereunder, nor will the failure of one Lender to perform
any of its obligations hereunder relieve the other Lenders from the performance
of their respective obligations hereunder.

SECTION 12  MISCELLANEOUS

         12.1 Headings. The headings, captions, and arrangements used in any of
the Loan Papers are, unless specified otherwise, for convenience only and shall
not be deemed to limit, amplify, or modify the terms of the Loan Papers, nor
affect the meaning thereof.

         12.2 Nonbusiness Days. In any case where any payment or action is due
under any Loan Paper on a day which is not a Business Day, such payment or
action may be delayed until the next-succeeding Business Day, but interest and
fees shall continue to accrue in respect of any payment to which it is
applicable until such payment is in fact made; provided that, if in the case of
any such payment in respect of a Eurodollar Rate Borrowing the next-succeeding
Business Day is in the next calendar month, then such payment shall be made on
the next-preceding Business Day.

<PAGE>

         12.3 Communications. Unless specifically otherwise provided, whenever
any Loan Paper requires or permits any consent, approval, notice, request, or
demand from one party to another, such communication must be in writing (which
may be by telex or telecopy) to be effective and shall be deemed to have been
given (a) if by telex, when transmitted to the telex number, if any, for such
party, and the appropriate answer back is received, (b) if by telecopy, when
transmitted to the telecopy number for such party (and all such communications
sent by telecopy shall be confirmed promptly thereafter by personal delivery or
mailing in accordance with the provisions of this section; provided, that any
requirement in this parenthetical shall not affect the date on which such
telecopy shall be deemed to have been delivered), (c) if by mail, on the third
Business Day after it is enclosed in an envelope, properly addressed to such
party, properly stamped, sealed, and deposited in the appropriate official
postal service, or (d) if by any other means, when actually delivered to such
party. Until changed by notice pursuant hereto, the address (and telex and
telecopy numbers, if any) for Administrative Agent and each Lender is set forth
on SCHEDULE 2.1, and for the Company is the address set forth by the Company's
signature on the signature page of this Agreement. A copy of each communication
to Administrative Agent shall also be sent to Haynes and Boone, LLP, 901 Main
Street, Dallas, Texas 75202, Fax: 214/651-5940, Attn: Timothy Powers.

         12.4 Form and Number of Documents. Each agreement, document,
instrument, or other writing to be furnished under any provision of this
Agreement must be in form and substance and in such number of counterparts as
may be reasonably satisfactory to Administrative Agent and its counsel.

         12.5 Exceptions to Covenants. The Company shall not take any action or
fail to take any action which is permitted as an exception to any of the
covenants contained in any Loan Paper if such action or omission would result in
the breach of any other covenant contained in any of the Loan Papers.

         12.6 Survival. All covenants, agreements, undertakings,
representations, and warranties made in any of the Loan Papers shall survive all
closings under the Loan Papers and, except as otherwise indicated, shall not be
affected by any investigation made by any party. All rights of, and provisions
relating to, reimbursement and indemnification of any Agent or any Lender shall
survive termination of this Agreement and payment in full of the Obligation.

         12.7 GOVERNING LAW. THE LAWS OF THE STATE OF NEW YORK AND OF THE UNITED
STATES OF AMERICA SHALL GOVERN THE RIGHTS AND DUTIES OF THE PARTIES TO THE LOAN
PAPERS AND THE VALIDITY, CONSTRUCTION, ENFORCEMENT, AND INTERPRETATION OF THE
LOAN PAPERS.

         12.8 Invalid Provisions. If any provision in any Loan Paper is held to
be illegal, invalid, or unenforceable, such provision shall be fully severable;
the appropriate Loan Paper shall be construed and enforced as if such provision
had never comprised a part thereof; and the remaining provisions thereof shall
remain in full force and effect and shall not be affected by such provision or
by its severance therefrom. Administrative Agent, Lenders, and the Company agree
to negotiate, in good faith, the terms of a replacement provision as similar to
the severed provision as may be possible and be legal, valid, and enforceable.

         12.9 ENTIRETY. THE RIGHTS AND OBLIGATIONS OF THE COMPANY, LENDERS, AND
AGENTS SHALL BE DETERMINED SOLELY FROM WRITTEN AGREEMENTS, DOCUMENTS, AND
INSTRUMENTS, AND ANY PRIOR ORAL AGREEMENTS BETWEEN SUCH PARTIES ARE SUPERSEDED
BY AND MERGED INTO SUCH WRITINGS. THIS AGREEMENT (AS AMENDED IN WRITING FROM
TIME TO TIME) AND THE OTHER WRITTEN LOAN PAPERS EXECUTED BY THE COMPANY, ANY
LENDER, OR ANY AGENT (TOGETHER WITH ALL COMMITMENT LETTERS AND FEE LETTERS AS
THEY RELATE TO THE PAYMENT OF FEES AFTER THE CLOSING DATE) REPRESENT THE FINAL
AGREEMENT BETWEEN THE COMPANY, LENDERS, AND AGENTS AND MAY NOT BE CONTRADICTED
BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR

         12.10 JURISDICTION; VENUE; SERVICE OF PROCESS; JURY TRIAL. EACH PARTY

TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY LOAN
PAPER OR THE TRANSACTIONS CONTEMPLATED THEREBY. The scope of each of the
foregoing waivers is intended to be all-encompassing of any and all disputes
that may be filed in any court and that relate to the subject matter of this
transaction, including, without limitation, contract claims, tort claims, breach
of duty claims, and all other common law and statutory claims. The Company and
each other party to this Agreement acknowledge that this waiver is a material
inducement to the agreement of each party hereto to enter into a business
relationship, that each has already relied on this waiver in entering into this
Agreement, and each will continue to rely on each of such waivers in related
future dealings. The Company and each other party to this Agreement warrant and
represent that they have reviewed these waivers with their legal counsel, and
that they knowingly and voluntarily agree to each such waiver following
consultation with legal counsel. THE WAIVERS IN THIS SECTION 12.10 ARE
IRREVOCABLE, MEANING THAT THEY MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING,
AND THESE WAIVERS SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, SUPPLEMENTS, AND
REPLACEMENTS TO OR OF THIS OR ANY OTHER LOAN PAPER. In the event of Litigation,
this Agreement may be filed as a written consent to a trial by the court.

         12.11 Amendments, Consents, Conflicts, and Waivers.

                  (a) Except as otherwise specifically provided, (i) this
         Agreement may only be amended, modified or waived by an instrument in
         writing executed jointly by the Company and Determining Lenders, and,
         in the case of any matter affecting Administrative Agent, by
         Administrative Agent, and may only be supplemented by documents
         delivered or to be delivered in accordance with the express terms
         hereof, and (ii) the other Loan Papers may only be the subject of an
         amendment, modification, or waiver if the Company and Determining
         Lenders, and, in the case of any matter affecting Administrative Agent,
         Administrative Agent, have approved same.

                  (b) Any amendment to or consent or waiver under this Agreement
         or any Loan Paper which purports to accomplish any of the following
         must be by an instrument in writing executed by the Company and
         executed (or approved, as the case may be) by each Lender, and, in the
         case of any matter affecting Administrative Agent, by Administrative
         Agent: (i) extends the due date or decreases the amount of any
         scheduled payment of the Obligation arising under Loan Papers beyond
         the date specified in the Loan Papers; (ii) reduces the interest rate
         or decreases the amount of interest, fees, or other sums payable to

         contemplated by this Agreement); or (iii) reduces the percentage
         specified in the definition of "DETERMINING LENDERS"; (iv) changes
         SECTION 3.2(c) or this CLAUSE (b) or any other matter specifically
         requiring the consent of all Lenders hereunder; or (v) consents to the
         assignment or transfer of the Company of any of its rights and
         obligations under this Agreement. Without the consent of Administrative
         Agent and Determining Lenders, no provision of SECTION 11 may be
         amended, modified, or waived. Each Designating Lender shall act on
         behalf of its Designated Lender with respect to any rights of its
         Designated Lender to grant or withhold any consent hereunder to the
         fullest extent it has been so delegated to act by its Designated Lender
         pursuant to its Designation Agreement.

                  (c) Any conflict or ambiguity between the terms and provisions
         herein and terms and provisions in any other Loan Paper shall be
         controlled by the terms and provisions herein.

         Administrative Agent, any Lender, or any of their respective
         Representatives with respect to exercising any Right of Administrative
         Agent or any Lender hereunder shall operate as a waiver thereof. A
         waiver must be in writing and signed by Administrative Agent and
         Determining Lenders (or by all Lenders, if required hereunder) to be
         effective, and such waiver will be effective only in the specific
         instance and for the specific purpose for which it is given.

         12.12 Multiple Counterparts. This Agreement may be executed in a number
of identical counterparts, each of which shall be deemed an original for all
purposes and all of which constitute, collectively, one agreement; but, in
making proof of this Agreement, it shall not be necessary to produce or account
for more than one such counterpart. It is not necessary that each Lender execute
the same counterpart so long as identical counterparts are executed by the
Company, each Lender, and Administrative Agent. This Agreement shall become
effective when counterparts hereof shall have been executed and delivered to
Administrative Agent by each Lender, Administrative Agent, and the Company, or,
when Administrative Agent shall have received telecopied, telexed, or other
evidence satisfactory to it that such party has executed and is delivering to
Administrative Agent a counterpart hereof.

         12.13 Successors and Assigns; Assignments and Participations.

                  (a) This Agreement shall be binding upon, and inure to the
         benefit of the parties hereto and their respective successors and
         assigns, except that (i) the Company may not, directly or indirectly,
         assign or transfer, or attempt to assign or transfer, any of its
         Rights, duties or obligations under any Loan Papers without the express
         written consent of all Lenders, and (ii) except as permitted under this
         Section, no Lender may transfer, pledge, assign, sell any participation
         in, or otherwise encumber its portion of the Obligation.

                  (b) Each Lender may assign to one or more Eligible Assignees
         all or a portion of its Rights and obligations under this Agreement and
         the other Loan Papers (including, without limitation, all or a portion
         of its Borrowings and its Note); provided, however, that:

                           (i) each such assignment shall be to an Eligible
                  Assignee;

                         (ii) except in the case of an assignment to another
                  Lender or an assignment of all of a Lender's Rights and
                  obligations under this Agreement and the other Loan Papers,
                  any such partial assignment shall be in an amount at least
                  equal to $10,000,000 (or such lower amount as may be requested
                  by a Lender and agreed to by Administrative Agent, acting in
                  its sole discretion);

                                      60              FIRST AMENDED AND RESTATED
                                                             TERM LOAN AGREEMENT
<PAGE>

                         (iii) each such assignment by a Lender shall be of a
                  constant, and not varying, percentage of all of its Rights and
                  obligations under this Agreement and the Notes; and

                         (iv) the parties to such assignment shall execute and
                  deliver to the Administrative Agent for its acceptance an
                  Assignment and Acceptance Agreement in the form of EXHIBIT C
                  hereto, together with any Notes subject to such assignment and
                  a processing fee of $3,000.

         Upon execution, delivery, and acceptance of such Assignment and
         Acceptance Agreement, the assignee thereunder shall be a party hereto
         and, to the extent of such assignment, have the obligations, Rights,
         and benefits of a Lender under the Loan Papers and the assigning Lender
         shall, to the extent of such assignment, relinquish its rights and be
         released from its obligations under the Loan Papers. Upon the
         consummation of any assignment pursuant to this Section, the Company
         shall issue appropriate Notes to the assignor and the assignee,
         reflecting such Assignment and Acceptance. If the assignee is not
         incorporated under the laws of the United States of America or a state
         thereof, it shall deliver to the Company and Administrative Agent
         certification as to exemption from deduction or withholding of Taxes in
         accordance with SECTION 4.6.

                  (c) Administrative Agent shall maintain at its address
         referred to in SECTION 12.3 a copy of each Assignment and Acceptance
         Agreement delivered to and accepted by it and a register for the
         recordation of the names and addresses of the Lenders and principal
         amount of the Borrowings owing to each Lender from time to time (the
         "REGISTER"). The entries in the Register shall be conclusive and
         binding for all purposes, absent manifest error, and the Company,
         Administrative Agent and Lenders may treat each Person whose name is
         recorded in the Register as a Lender hereunder for all purposes of the
         Loan Papers. The Register shall be available for inspection by the
         Company or any Lender at any reasonable time and from time to time upon
         reasonable prior notice. Upon the consummation of any assignment in
         accordance with this SECTION 12.13, SCHEDULE 2.1 shall automatically be
         deemed amended (to the extent required) by Administrative Agent to
         reflect the name, address, and respective Pro Rata Part of the
         Principal Debt of the assignor and assignee.

                  (d) Upon its receipt of an Assignment and Acceptance Agreement
         executed by the parties thereto, together with any Notes subject to
         such assignment and payment of the processing fee, Administrative Agent
         shall, if such Assignment and Acceptance has been completed and is in
         substantially the form of EXHIBIT C hereto, (i) accept such Assignment
         and Acceptance Agreement, (ii) record the information contained therein
         in the Register and (iii) give prompt notice thereof to the parties
         thereto.

                  (e) Subject to the provisions of this Section and in
         accordance with applicable Law, any Lender may, in the ordinary course
         of its commercial lending business and in accordance with applicable
         Law, at any time sell to one or more Persons (each a "PARTICIPANT")
         participating interests in its portion of the Obligation. In the event
         of any such sale to a Participant, (i) such Lender shall remain a
         "Lender" under this Agreement and the Participant shall not constitute
         a "Lender" hereunder, (ii) such Lender's obligations under this
         Agreement shall remain unchanged, (iii) such Lender shall remain solely
         responsible for the performance thereof, (iv) such Lender shall remain
         the holder of its share of the Principal Debt for all purposes under
         this Agreement, (v) the Company and Administrative Agent shall continue
         to deal solely and directly with such Lender in connection with such
         Lender's Rights and obligations under the Loan Papers, and (vi) such
         Lender shall be solely responsible for any withholding taxes or any
         filing or reporting requirements relating to such participation and
         shall hold the Company and Administrative Agent and their respective
         successors, permitted assigns, officers, directors, employees, agents,
         and representatives harmless against the same. Participants shall have
         no Rights under the Loan Papers, other than certain voting Rights as

                                      61              FIRST AMENDED AND RESTATED
                                                             TERM LOAN AGREEMENT

<PAGE>

         provided below. Subject to the following, each Lender shall be entitled
         to obtain (on behalf of its Participants) the benefits of SECTION 4
         with respect to all participations in its part of the Obligation
         outstanding from time to time so long as the Company shall not be
         obligated to pay any amount in excess of the amount that would be due
         to such Lender under SECTION 4 calculated as though no participations
         have been made. No Lender shall sell any participating interest under
         which the Participant shall have any Rights to approve any amendment,
         modification, or waiver of any Loan Paper, except to the extent such
         amendment, modification, or waiver extends the due date for payment of
         any amount in respect of principal (other than mandatory prepayments),
         interest, or fees due under the Loan Papers, reduces the interest rate
         or the amount of principal or fees applicable to the Obligation (except
         such reductions as are provided by this Agreement), or releases any
         guaranty or collateral, if any, for the Obligation (except such
         releases as are contemplated by this Agreement); provided that, in
         those cases where a Participant is entitled to the benefits of SECTION
         4 or a Lender grants Rights to its Participants to approve amendments
         to or waivers of the Loan Papers respecting the matters previously
         described in this sentence, such Lender must include a voting mechanism
         in the relevant participation agreement or agreements, as the case may
         be, whereby a majority of such Lender's portion of the Obligation
         (whether held by such Lender or Participant) shall control the vote for
         all of such Lender's portion of the Obligation. Except in the case of
         the sale of a participating interest to another Lender, the relevant
         participation agreement shall not permit the Participant to transfer,
         pledge, assign, sell participations in, or otherwise encumber its
         portion of the Obligation, unless the consent of the transferring
         Lender (which consent will not be unreasonably withheld) has been
         obtained.

                  (f) Any Lender may at any time designate not more than one
         Designated Lender to fund Borrowings on behalf of such Designating
         Lender subject to the terms of this SECTION 12.13(f), and the
         provisions of SECTIONS 12.13(b) AND 12.13(e) shall not apply to such
         designation. No Lender may have more than one Designated Lender at any
         time. Such designation may occur either by the execution of the
         signature pages hereof by such Lender and Designated Lender next to the
         appropriate "Designating Lender" and "Designated Lender" captions, or
         by execution by such parties of a Designation Agreement subsequent to
         the date hereof; provided, that any Lender and its Designated Lender
         executing the signatures pages hereof as "Designating Lender" and
         "Designated Lender", respectively, on the date hereof shall be deemed
         to have executed a Designation Agreement, and shall be bound by the
         respective representations, warranties and covenants contained therein,
         and such designation shall be conclusively deemed to be accepted by the
         Company and the Administrative Agent. The parties to each such
         designation occurring subsequent to the execution date hereof shall
         execute and deliver to the Administrative Agent and the Company for
         their acceptance a Designation Agreement. Upon such receipt of an
         appropriately completed Designation Agreement executed by a Designating
         Lender and a designee representing that it is a Designated Lender and
         consented to by the Company and the Administrative Agent, the
         Administrative Agent will accept such Designation Agreement and will
         give prompt notice thereof to the Company and the other Lenders,
         whereupon, (i) the Company shall execute and deliver to the Designating
         Lender a Designated Lender Note payable to the order of the Designated
         Lender, (ii) from and after the effective date specified in the
         Designation Agreement, the Designated Lender shall become a party to
         this Agreement with a right to fund Borrowings on behalf of its
         Designating Lender pursuant to SECTION 2.1(b), and (iii) the Designated
         Lender shall not be required to make payments with respect to any
         obligations in this Agreement except to the extent of excess cash flow
         of such Designated Lender which is not otherwise required to repay
         obligations of such Designated Lender which are then due and payable;
         provided, however, that regardless of such designation and assumption
         by the Designated Lender, the Designating Lender shall be and remain
         obligated to the Company, the Administrative Agent and the Lenders for
         each and every of the obligations of the Designating Lender and its
         related Designated Lender with respect to this Agreement, including,
         without limitation, any indemnification obligations

                                      62              FIRST AMENDED AND RESTATED
                                                             TERM LOAN AGREEMENT

<PAGE>

         under SECTION 11.5(c) hereof and any sums otherwise payable to the
         Company by the Designated Lender.

                  Each Designating Lender, or a specified branch or affiliate
         thereof, shall serve as the administrative agent of its Designated
         Lender and shall on behalf of its Designated Lender: (i) receive any
         and all payments made for the benefit of such Designated Lender and
         (ii) give and receive all communications and notices and take all
         actions hereunder, including, without limitation, votes, approvals,
         waivers, consents and amendments under or relating to this Agreement
         and the other Loan Papers. Any such notice, communication, vote,
         approval, waiver, consent or amendment shall be signed by a Designating
         Lender, or specified branch or affiliate thereof, as administrative
         agent for its Designated Lender and need not be signed by such
         Designated Lender on its own behalf. The Company, the Administrative
         Agent and the Lenders may rely thereon without any requirement that the
         Designated Lender sign or acknowledge the same. No Designated Lender
         may assign or transfer all or any portion of its interest hereunder or
         under any other Loan Paper, other than pursuant to an assignment to its
         Designating Lender pursuant to a pledge to its Liquidity Lender (if
         any) in accordance with SECTION 12.13(g) of this Agreement, or
         otherwise in accordance with the provisions of this SECTION 12.13.

                  (g) Notwithstanding any other provision set forth in this
         Agreement, (i) any Lender may at any time assign and pledge all or any
         portion of its Borrowings and its Note to any Federal Reserve Bank as
         collateral security pursuant to Regulation A and any Operating Circular
         issued by such Federal Reserve Bank. No such assignment shall release
         the assigning Lender from its obligations hereunder and (ii) any
         Designated Lender may at any time create a security interest in, or
         pledge, all or any portion of its rights under and interest in this
         Agreement and the Designated Lender Note held by it in favor of its
         Liquidity Bank, and such Liquidity Bank may enforce such pledge or
         security interest in any manner permitted under applicable law,
         provided that (y) such Liquidity Bank possesses the characteristics
         necessary to be an Eligible Assignee under this Agreement, and (z) no
         such pledge shall release the Designating Lender from its obligations
         hereunder or grant to such Liquidity Bank the rights of a Lender
         hereunder absent foreclosure of such pledge.

                  (h) Any Lender may furnish any information concerning the
         Company in the possession of such Lender from time to time to Eligible
         Assignees and Participants (including prospective Eligible Assignees
         and Participants), subject, however, to SECTION 12.15 hereof.

         12.14 Discharge Only Upon Payment in Full; Reinstatement in Certain
Circumstances. The Company's obligations under the Loan Papers shall remain in
full force and effect until payment in full of the Principal Debt and of all
interest, fees, and other amounts of the Obligation then due and owing, except
that SECTION 4, SECTION 10, and SECTION 12, and any other provisions under the
Loan Papers expressly intended to survive by the terms hereof or by the terms of
the applicable Loan Papers, shall survive such termination. If at any time any
payment of the principal of or interest on any Note or any other amount payable
by the Company under any Loan Paper is rescinded or must be otherwise restored
or returned upon the insolvency, bankruptcy, or reorganization of the Company or
otherwise, the obligations of the Company under the Loan Papers with respect to
such payment shall be reinstated as though such payment had been due but not
made at such time.

         12.15 Confidentiality. Administrative Agent and each Lender (each, a
"LENDING PARTY") agrees to use its best efforts to keep confidential any
information furnished or made available to it by the Company pursuant to this
Agreement that is marked confidential; provided that nothing herein shall
prevent any Lending Party from disclosing such information (a) to any other
Lending Party or any officer, director, employee, agent, or advisor of any
Lending Party, (b) to its auditors, accountants, legal counsel or other
professional advisors,

                                      63              FIRST AMENDED AND RESTATED

<PAGE>

(c) as required by any law, rule, or regulation, (d) upon the order of any court
or administrative agency, (e) upon the request or demand of any regulatory
agency or authority, (f) that is or becomes available to the public or that is
or becomes available to any Lending Party other than as a result of a disclosure
by any Lending Party prohibited by this Agreement, (g) in connection with any
litigation to which such Lending Party or any of its affiliates may be a party,
(h) to the extent necessary in connection with the exercise of any remedy under
this Agreement or any other Loan Paper, and (i) subject to provisions
substantially similar to those contained in this Section, to any Affiliate of
any Lending Party or to any actual or proposed participant or assignee. The
Company hereby consents to the disclosure of any non-public information with
respect to it which is related to this transaction by any Designated Lender to
any rating agency, commercial paper dealer, or provider of a surety, guaranty or
credit or liquidity enhancement to such Designated Lender.

         12.16 No Bankruptcy Proceedings. Each of the Company, the Lenders and
the Administrative Agent agrees that it will not institute against any
Designated Lender or join any other Person in instituting against any Designated
Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceeding under any federal or state bankruptcy or similar law, for one year
and one day after the payment in full of the latest maturing commercial paper
note issued by such Designated Lender; provided that the Designating Lender
hereby agrees to indemnify, save and hold harmless the Company, each Lender and
the Administrative Agent for any loss, cost, damage and expense arising out of
their inability to institute any such proceeding against its Designated Lender.

         12.17 Guaranties. As an inducement to the Administrative Agent and the
Lenders to enter into this Agreement, each Guarantor has executed and delivered
to the Administrative Agent this Agreement to (i) ratify and reaffirm their
respective obligations under the LLC Guaranty and the Holdings Guaranty, as
applicable, and (ii) evidence its acknowledgement, consent, and agreement (a) to
the execution, delivery, and performance of this Agreement by the Company, and
(b) that this Agreement in no way releases, diminishes, impairs, reduces, or
otherwise adversely affects any guaranties, assurances, or other obligations or
undertakings of such Guarantor under any Loan Paper.

         12.18 Existing Defaults of No Effect. Any default which has occurred
and is continuing under the Existing Loan Agreement, if any, shall, upon the
satisfaction of the conditions set forth in SECTION 6.1, be deemed to be fully
and completely remedied and of no further force and effect, except to the extent
that the event or condition causing such default shall constitute a Default or a
Potential Default under this Agreement. Without limiting the generality of the
foregoing, the Lenders hereby waive the condition precedent to the effectiveness
of the Fifth Amendment to Term Loan Agreement dated as of July 31, 2002 (the
"Fifth Amendment") that the Company provide a satisfactory legal opinion of its
special counsel, Skadden Arps, Slate, Meagher & Flom LLP contained in Paragraph
3(d) of the Fifth Amendment.

         EXECUTED on the respective dates shown on the signature pages hereto,
but effective as of the Closing Date.

dated as of October 31, 2002 (as amended, modified, supplemented, or restated
from time to time, the "AGREEMENT") among THE WILLIAMS COMPANIES, INC., a

otherwise defined herein shall have the meanings assigned to such terms in the
Agreement.

         The "ASSIGNOR" and the "ASSIGNEE" referred to on SCHEDULE 1 agree as
follows:

         1. The Assignor hereby sells and assigns to the Assignee, without
recourse and without representation or warranty except as expressly set forth
herein, and the Assignee hereby purchases and assumes from the Assignor, an
interest in and to the Assignor's Rights and obligations under the Agreement and
the related Loan Papers as of the date hereof equal to the percentage interest
specified on SCHEDULE 1. After giving effect to such sale and assignment, the
Assignor's and the Assignee's amount of the Borrowings under the Term Facility
owing to each of them will be as set forth on SCHEDULE 1.

         2. The Assignor (i) represents and warrants that it is the legal and
beneficial owner of the interest being assigned by it hereunder and that such
interest is free and clear of any adverse claim; (ii) makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with the Loan Papers or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of the Loan Papers or any other instrument or document furnished pursuant
thereto; (iii) makes no representation or warranty and assumes no responsibility
with respect to the financial condition of any party to any Loan Paper or the
performance or observance by any such party of any of its obligations under the
Loan Papers or any other instrument or document furnished pursuant thereto; and
(iv) attaches the Note held by the Assignor and requests that Administrative
Agent exchange such Note for new Notes. Such new Notes shall be prepared in
accordance with the provisions of SECTION 3.1(a) of the Agreement and will
reflect the respective Borrowings of the Assignee and the Assignor after giving
effect to this Assignment and Acceptance.

         3. The Assignee (i) confirms that it has received a copy of the
Agreement, together with copies of the current financials statements of the
Company furnished pursuant to the Agreement and such other documents and
information as it has deemed appropriate to make its own credit analysis and
decision to enter into this Assignment and Acceptance; (ii) agrees that it will,
independently and without reliance upon the Administrative Agent, the Assignor,
or any other Lender, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under the Agreement; (iii) confirms that it is an
Eligible Assignee; (iv) appoints and authorizes Administrative Agent to take
such action as Administrative Agent on its behalf and to exercise such powers
and discretion under the Agreement as are delegated to Administrative Agent by
the terms thereof, together with such powers and discretion as are reasonably
incidental thereto; (v) agrees that it will perform in accordance with their
terms all of the obligations that by the terms of the Agreement are required to
be performed by it as a Lender.

         4. Following the execution of this Assignment and Acceptance, it will
be delivered to Administrative Agent for acceptance and recording by the
Administrative Agent. The effective date for this Assignment and Acceptance (the
"EFFECTIVE DATE") shall be the date of acceptance hereof by Administrative
Agent, unless otherwise specified on SCHEDULE 1.

                                                                       Exhibit C

the Effective Date, (i) the Assignee shall be a party to the Agreement and, to
the extent provided in this Assignment and Acceptance, have the Rights and
obligations of a Lender thereunder, and (ii) the Assignor shall, to the extent
provided in this Assignment and Acceptance, relinquish its Rights and be
released from its obligations under the Agreement.

         6. Upon such acceptance and recording by Administrative Agent, from and
after the Effective Date, Administrative Agent shall make all payments under the
Agreement, the Notes, and loan accounts in respect of the interest assigned
hereby (including, without limitation, all payments of principal, interest, and
commitment fees and other fees with respect thereto) to the Assignee. The
Assignor and Assignee shall make all appropriate adjustments in payments under
the Agreement and the other Loan Papers for periods prior to the Effective Date
directly between themselves.

         7. Unless the Assignee is a Lender or an Affiliate of a Lender (and
this sale and assignment is not made in connection with the sale of such
Affiliate), this Assignment and Acceptance may be conditioned upon the consent
of the Company and Administrative Agent pursuant to the definition of "Eligible
Assignee" in the Agreement. The execution and delivery of this Assignment and
Acceptance by the Company and Administrative Agent is evidence of this consent.

Assignor or the Assignee (as determined between the Assignor and the Assignee)
agrees to pay to Administrative Agent for its account on the Effective Date in
federal funds a processing fee of $3,000.

CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE UNITED STATES OF
AMERICA AND THE STATE OF NEW YORK.

         10. This Assignment and Acceptance may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement. Delivery of an executed
