other than those in existence on the date hereof.  Notwithstanding the
foregoing, a Sponsor may amend one or more existing credit agreements or similar
documents, or may refinance one or more existing credit agreements or similar
documents (either with the same lenders or with new lenders), provided that such
amended or new credit agreements or similar documents do not create any
additional restrictions not in existence on the date hereof.

Affiliates to pay, to Agent, for the benefit of itself and the Lenders, any and
all dividends, distributions or payments of any kind made to any

existence.

(e)                                  Each Sponsor will do or cause to be done
all things necessary to preserve and maintain all of its rights, licenses,
permits, privileges, and franchises material to the conduct of its business,
except where failure to do so could not reasonably be expected to have a
material adverse effect on its ability to perform its obligations hereunder.

(f)                                    Each Sponsor will comply in all material
respects with the requirements of all applicable laws, except where the failure
to comply could not reasonably be expected to have a material adverse effect on
its ability to perform its obligations hereunder.

2.             Representations.  Each Sponsor represents and warrants to Agent
and Lenders as of the date of this Agreement:

(a)                                  Each Sponsor is a company duly organized,
validly existing and in good standing under the laws of the state of its

under this Agreement and to carry on its business as now conducted; the
execution, delivery and performance by it of this Agreement has been duly
authorized by all necessary corporate, partnership or other like action on its
part and this Agreement has been duly and validly executed and delivered by it
and constitutes its legal, valid and binding obligation, enforceable against it
in accordance with its terms, except as such enforceability may be limited by
(i) bankruptcy, insolvency, reorganization, moratorium or similar laws of
general applicability affecting the enforcement of creditors’ rights and (ii)
the application of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

(c)                                  No authorizations, approvals, or consents
of, and no filings or registrations with, any Governmental Authority (other than
those already obtained), are necessary or advisable for (i) the execution,
delivery or performance by each Sponsor of this Agreement and (ii) the legality,
validity, binding effect or enforceability hereof or thereof.

(d)                                 Except as set forth on Schedule 2(d) hereto,
neither the execution and delivery of this Agreement, nor each Sponsor’s
compliance with or performance of the terms and provisions hereof or thereof
(i) will require the consent of or approval of any of Sponsors’ creditors, (ii)
will conflict with, violate, result in a breach of or require any consent under,
any contract to which any Sponsor is a party or bound, (iii) will conflict with
or result in a breach of, or require any consent under, either Sponsor’s charter

injunction or decree of any court or

Agent or Lenders in exercising any right or power hereunder shall operate as a

power, preclude any other or further exercise thereof or the exercise of any
other right or power.  The rights and remedies of the Borrower and Agent and
Lenders hereunder are cumulative and are not exclusive of any rights or remedies
that they would otherwise have.  No waiver of any provision of this Agreement or

--------------------------------------------------------------------------------

9.             Severability.  Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or

a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

10.           Governing Law; Submission to Jurisdiction; Etc.  EACH PARTY HERETO
HEREBY CONSENTS AND AGREES THAT:

(a)                                  THIS AGREEMENT SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF NEW YORK.

(b)                                 THE STATE OR FEDERAL COURTS LOCATED IN NEW
YORK COUNTY, STATE OF NEW YORK, SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND
DETERMINE ANY CLAIMS OR DISPUTES BETWEEN SPONSORS, AGENT AND LENDERS PERTAINING
TO THIS AGREEMENT OR TO ANY MATTER ARISING OUT OF OR RELATING TO THIS AGREEMENT,
PROVIDED, THAT AGENT, LENDERS AND SPONSORS ACKNOWLEDGE THAT ANY APPEALS FROM
THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE NEW YORK COUNTY. 
SPONSORS EXPRESSLY SUBMIT AND CONSENT IN ADVANCE TO SUCH JURISDICTION IN ANY
ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND EACH SPONSOR HEREBY WAIVES ANY
OBJECTION WHICH IT MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER
VENUE OR FORUM NON CONVENIENS.  EACH SPONSOR HEREBY WAIVES PERSONAL SERVICE OF
THE SUMMONS, COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT AND
AGREES THAT SERVICE OF SUCH SUMMONS, COMPLAINTS AND OTHER PROCESS MAY BE MADE BY
REGISTERED OR CERTIFIED MAIL ADDRESSED TO SUCH SPONSOR AT THE ADDRESS SET FORTH
IN SECTION 5 HEREOF AND THAT SERVICE SO MADE SHALL BE DEEMED COMPLETED UPON THE
EARLIER OF ACTUAL RECEIPT THEREOF OR FIVE (5) DAYS AFTER DEPOSIT IN THE U.S.
MAILS, PROPER POSTAGE PREPAID.  NOTWITHSTANDING THE FOREGOING, EACH SPONSOR
HEREBY APPOINTS CT CORPORATION SYSTEM, LOCATED 111 EIGHTH AVENUE, 13TH FLOOR,
NEW YORK, NY 10011, U.S.A. AS ITS AGENT FOR SERVICE OF PROCESS IN ANY PROCEEDING
IN ANY COURTS LOCATED IN THE CITY OF NEW YORK IN CONNECTION WITH THIS AGREEMENT.

(c)                                  BECAUSE DISPUTES ARISING IN CONNECTION WITH
COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN
EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND FEDERAL
LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT DISPUTES
ARISING HEREUNDER OR RELATING HERETO BE RESOLVED BY A JUDGE APPLYING SUCH
APPLICABLE LAWS.  THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF
THE JUDICIAL SYSTEM AND OF ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHT TO
TRIAL BY JURY

5

--------------------------------------------------------------------------------

IN ANY ACTION, SUIT OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, WHETHER
SOUNDING IN CONTRACT, TORT, OR OTHERWISE, AMONG AGENT AND/OR LENDERS AND
SPONSORS ARISING OUT OF, CONNECTED WITH, RELATED TO OR INCIDENTAL TO THE
RELATIONSHIP ESTABLISHED IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS
RELATED HERETO.

11.           Counterparts.  This Agreement may be executed in two or more
counterparts (and by different parties hereto on different counterparts), each
of which shall constitute an original, but all of which when taken together
shall constitute a single contract.  This Agreement constitutes the entire
contract between and among the parties relating to the subject matter hereof and
supersedes any and all previous agreements and understandings, oral or written,
relating to the subject matter hereof.  This Agreement shall become effective
when it shall have been executed by each of the parties that appear in the
preamble hereto and when Agent shall have received counterparts hereof which,
when taken together, bear the signatures of each of the other parties hereto,
and thereafter shall be binding upon and inure to the benefit of the parties
hereto, Lenders and their respective successors and assigns.  Delivery of an
executed counterpart of a signature page to this Agreement by telecopy shall be
effective as delivery of a manually executed counterpart of this Agreement.

12.           Headings.  Section headings used herein are for convenience of
reference only, are not part of this Agreement and shall not affect the
construction of, or be taken into consideration in interpreting, this Agreement.

13.           Expenses.  Sponsors will, upon demand, pay to Agent and Lenders
all reasonable fees and expenses, including attorney’s fees and expenses,
incurred by Agent and/or Lenders in connection with the exercise or enforcement
of any of their rights, remedies or interests under or related to this
Agreement.
