in good standing under the Laws of the State of Delaware and has the requisite

                                       7

corporate power and corporate authority to carry on its business as it is now
being conducted or presently proposed to be conducted. To the Company's
Knowledge, the Company is duly qualified and licensed as a foreign corporation
to do business and is in good standing (and has paid all relevant franchise or
analogous taxes) in each jurisdiction where the character of its assets owned or
held under lease or the nature of its business makes such qualification
necessary, except where the failure to be so qualified or licensed, individually
or in the aggregate, has not had and would not reasonably be expected to have a
Material Adverse Effect.

          (b) The Company owns, either directly or indirectly through one or
more of its Subsidiaries, all of the capital stock or other equity interests of
its Subsidiaries free and clear of all Liens, except those Liens pursuant to the
credit and other loan agreements existing as of the date hereof. There are no
outstanding subscription rights, options, warrants, convertible or exchangeable
securities or other rights of any character whatsoever relating to issued or
unissued capital stock or other equity interests of any Subsidiary, or any
commitments of any character whatsoever relating to issued or unissued capital
stock or other equity interests of any Subsidiary or pursuant to which any
Subsidiary is or may become bound to issue or grant additional shares of its
capital stock or other equity interests or related subscription rights, options,
warrants, convertible or exchangeable securities or other rights, or to grant
preemptive rights.

          (c) Each Subsidiary is a corporation, limited liability company,
partnership, business association or other Person duly organized, validly
existing and in good standing (in jurisdictions where such concept is
recognized) under the Laws of the jurisdiction of its organization and has the
requisite corporate power and authority to carry on its business as it is now
being conducted. To the Company's Knowledge, each Subsidiary of the Company is
duly qualified and licensed as a foreign corporation or other business entity to
do business and is in good standing (and has paid all relevant franchise or
analogous taxes) in each jurisdiction where the character of its assets owned or
held under lease or the nature of its business makes such qualification
necessary, except where the failure of one or more Subsidiaries to be so
qualified or licensed, individually or in the aggregate, has not had and would
not be reasonably expected to have a Material Adverse Effect.

          Section 4.2 Due Authorization.

          (a) The Company has all corporate right, power and authority to enter
into this Agreement and to consummate the transactions contemplated hereby. The
(a) execution and delivery by the Company of this Agreement, (b) issuance, sale
and delivery of the Shares by the Company and (c) compliance by the Company with
each of the provisions of this Agreement (i) are within the corporate power and
authority of the Company and (ii) have been duly authorized by all requisite

                                       8

corporate action of the Company. This Agreement has been duly and validly
executed and delivered by the Company, and (assuming this Agreement constitutes
a valid and binding obligation of the Investors) this Agreement constitutes a
legal, valid and binding agreement of the Company, enforceable against the
Company in accordance with its terms, except as such enforcement is limited by
bankruptcy, insolvency, reorganization, moratorium and other similar Laws
affecting the enforcement of creditors' rights generally and limitations imposed
by general principles of equity.

          (b) The Shares have been duly authorized by the Company and, when
issued, sold and delivered in accordance with this Agreement, the Shares will be
validly issued, fully paid and nonassessable, free and clear of all Liens, and
the issuance thereof will not be subject to any preemptive rights, right of
first refusal or similar right. At the Closing, no further approval or authority
of the stockholders or the Board of Directors under the Delaware General

that in the event this Agreement is terminated in accordance with this Section
8.1, no Investor Indemnified Person may seek indemnification from the Company
pursuant to Article IX hereof other than for the reasonable out-of-pocket fees,
costs or expenses incurred by such Investor Indemnified Person in connection
with the Transactions):

          (a) by the Investors or the Company if the Contribution Agreement is
terminated in accordance with its terms;

          (b) by the Investors or the Company if there shall be any Law that
makes consummation of the purchase of the Shares hereunder illegal or otherwise
prohibited or if any court of competent jurisdiction or governmental authority
shall have issued an order, decree, ruling or taken any other action
restraining, enjoining or otherwise prohibiting the purchase of the Shares
hereunder and such order, decree, ruling or other action shall have become final
and non-appealable;

          (c) by the Investors or the Company if the Closing shall not have
occurred within 180 days of the date of this Agreement.

          (d) by the Company with respect to any particular Investor if such
Investor shall have breached in any respect any of its representations,
warranties, covenants or other agreements contained in this Agreement that would
give rise to the failure of a condition set forth in Article VII; or

          (e) by the Investors if the Company shall have breached in any respect
any of its covenants or other agreements contained in this Agreement that would
give rise to the failure of a condition set forth in Article VII.

                                   ARTICLE IX

                                 INDEMNIFICATION

          Section 9.1 Survival of Representations and Warranties. The
representations and warranties of the parties hereto contained in this Agreement
shall expire twelve months after the Closing Date, except that the
representations and warranties set forth in Sections 4.1(a), 4.2, 4.3, 5.1, 5.2,
5.3 and 5.4 shall survive until 6 months after the expiration of the applicable
statute of limitations (including any extensions thereof). After the expiration
of such periods, any claim by a party hereto based upon any such representation
or warranty shall be of no further force and effect, except to the extent a
party has asserted a claim in accordance with this Article IX for breach of any
such representation or warranty prior to the expiration of such period, in which
event any representation or warranty to which such claim relates shall survive
with respect to such claim until such claim is resolved as provided in this
Article IX. The covenants and agreements of the parties hereto contained in this
Agreement shall survive the Closing until performed in accordance with their
terms.

          Section 9.2 Indemnification.

          (a) The Company shall indemnify, defend and hold harmless the
Investors, their Affiliates, and their respective officers, directors, partners,
members, employees, agents, representatives, successors and assigns (each an
"Investor Indemnified Person") from and against all Losses incurred or suffered
by a Investor Indemnified Person arising from, relating to or as a result of (i)
the breach of any of the representations or warranties made by the Company in
this Agreement or in any certificate furnished by the Company to the Investor
pursuant to this Agreement (which breach shall be determined without regard to
any materiality or Material Adverse Effect qualifications contained in the
representation and warranty giving rise to such claim for indemnity), (ii) the
breach of any covenant, obligation or agreement made by the Company in this
Agreement or (iii) any actual or threatened Litigation against such Investor
Indemnified Person by any Person (other than an Investor Indemnified Person) in
connection with (A) the transactions contemplated hereby, (B) the negotiation,
execution, delivery and performance of this Agreement or (C) any actions taken
by any Investor Indemnified Person pursuant hereto or thereto or in connection
with the transactions contemplated hereby (whether or not the transactions
contemplated hereby are consummated); provided, however, that the Company shall
not have any obligation to indemnify a particular Investor Indemnified Person
pursuant to this Section 9.2(a)(iii) to the extent such suit, action, claim or
proceeding arises from a breach of this Agreement by such Investor or such
Investor Indemnified Person or a failure of any representation or warranty of
such Investor set forth in Article V hereof to be true and correct and such
breach or failure

                                       22

of a representation or warranty to be true and correct results in any condition
contained in Sections 7.1 or 7.3 hereof being incapable of being satisfied prior
to the Closing.

          (b) Each Investor shall severally and not jointly indemnify, defend
and hold harmless (i) the Company, its Affiliates, and their respective
officers, directors, partners, members, employees, agents, representatives,
successors and assigns and (ii) each other Investor and its Affiliates, and
their respective officers, directors, partners, members, employees, agents,
representatives, successors and assigns (each an "Indemnified Person") from and
against all Losses incurred or suffered by an Indemnified Person arising from,
relating to, or as a result of (i) the breach of any of the representations or
warranties made by such Investor in this Agreement or any certificate furnished
by such Investor to the Company pursuant to this Agreement or (ii) the breach of
any covenant, obligation or agreement made by such Investor in this Agreement.

          (c) No claim may be made against the Company for indemnification with
respect to breaches of representations and warranties pursuant to Section
9.2(a)(i) above with respect to any Losses unless the aggregate amount of Losses
incurred by the Investor Indemnified Persons thereunder exceeds $10,000,000, and
the Company shall then only be liable for the amount of such Losses which exceed
$10,000,000. The maximum amount recoverable under Section 9.2(a)(i) by all
Investor Indemnified Persons, in the aggregate, shall be the Purchase Price and
the maximum amount recoverable under Section 9.2(a)(i) by an Investor and its
Investor Indemnified Persons shall not exceed such Investor's Purchase Price. No
claim may be made against an Investor for indemnification with respect to
breaches of representations and warranties pursuant to Section 9.2(b)(i) above
with respect to any Losses unless the aggregate amount of Losses incurred by the
Indemnified Persons thereunder exceeds $10,000,000, and such Investor shall then
only be liable for the amount of such Losses which exceed $10,000,000. With
respect to each Investor, the maximum amount recoverable under Section 9.2(b)(i)
by all Indemnified Persons from such Investor shall be equal to the Purchase
Price of the Shares such Investor is required to purchase pursuant to Section
2.2, provided however, if such Investor shall have purchased a number of Shares
larger than the number of Shares such Investor was required to purchase pursuant
to Section 2.2, the maximum amount recoverable under Section 9.2(b)(i) by all
Indemnified Persons from such Investor shall be equal to the Purchase Price of
the Shares such Investor purchased pursuant to this Agreement.

          (d) In no case shall any payment be made in the case of an
indemnification claim under Section 9.2(a)(i) or 9.2(a)(ii) until a Loss occurs.
No Person shall have any liability to any Investor Indemnified Person under
Section 9.2(a)(i) for any breach of a representation or warranty to the extent
that a

                                       23

claim for indemnification is based upon facts of which such Investor Indemnified
Person had knowledge on or prior to the Closing Date, unless such claim also
relies upon a materially adverse occurrence or development that occurs after the
Closing Date. For purposes of this Section 9.2(d), (i) the Investors shall be
deemed to have knowledge of a fact only if any of the Persons set forth in the
definition of " Fortress Representative" or "Greenhill Representative" or
"Abrams Representative" has knowledge of the particular fact and (ii) such
individual shall be deemed to have knowledge only to the extent of his or her
actual knowledge of such fact and only to the extent of his or her awareness
that such fact constitutes a breach of such representation or warranty.

          Section 9.3 Procedure for Indemnification.

          (a) If an Investor Indemnified Person or an Indemnified Person (such
Person being referred to as the "Indemnitee") shall receive notice or otherwise
learn of the assertion by a Person who is not a party to this Agreement of any
claim or of the commencement by any such Person of any action (a "Claim") with
respect to which the other party (the "Indemnifying Party") may be obligated to
provide indemnification, such Indemnitee shall give such Indemnifying Party
written notice thereof promptly after becoming aware of such Claim; provided,
that the failure of any Indemnitee to give notice as provided in this Section
9.3 shall not relieve the applicable Indemnifying Party of its obligations under
this Article IX, except to the extent that such Indemnifying Party is materially
prejudiced by such failure to give notice; provided, further, that the
applicable Indemnifying Party shall have no obligations under Section 9.2(a)(i)
or Section 9.2(b)(i), as applicable, unless such written notice is received by
the Indemnifying Party within the survival periods set forth in Section 9.1.
Such notice shall describe the Claim in reasonable detail, and shall indicate
the amount (estimated if necessary) of the Loss that has been or may be
sustained by or is claimed against such Indemnitee.

          (b) An Indemnifying Party may elect to compromise, settle or defend,
at such Indemnifying Party's own expense and by such Indemnifying Party's own
counsel, any Claim; provided, however, that the Indemnifying Party shall not
compromise, settle or defend a Claim without the consent of the Indemnitee
(which consent shall not be unreasonably withheld, conditioned or delayed). If
an Indemnifying Party elects to compromise, settle or defend a Claim, it shall,
within 30 days of the receipt of notice from an Indemnitee pursuant to Section
9.3(a) (or sooner, if the nature of such Claim so requires), notify the
applicable Indemnitee of its intent to do so, and such Indemnitee shall
cooperate in a commercially reasonable manner in the compromise or settlement
of, or defense against, such Claim. After notice from an Indemnifying Party to
an Indemnitee of its election to assume the defense of a Claim, the Indemnitee
shall have the right to participate in the defense thereof, at its own expense,
and such Indemnifying Party shall not be liable to such

                                       24

Indemnitee under this Article IX for any legal or other expenses subsequently
incurred by such Indemnitee in connection with the defense thereof (except
expenses approved in advance by the Indemnitee); provided, that such Indemnitee
shall have the right to employ one separate counsel reasonably satisfactory to
the Indemnifying Party to represent such Indemnitee if (i) in the reasonable
judgment of the Indemnitee, there are legal defenses available to such
Indemnitee that are different from or additional to those available to the
Indemnifying Party, (ii) the Indemnifying Party shall authorize in writing the
Indemnitee to retain a single, separate counsel at the Indemnifying Party's
expense or (iii) the defendants in any such Claim include both the Indemnifying
Party and the Indemnitee and, in such Indemnitee's reasonable judgment, a
conflict of interest between such Indemnitee and such Indemnifying Party exists
in respect of such Claim, and only in the events listed in clauses (i) through
(iii) of this paragraph (b) shall the reasonable fees and expenses of such
separate counsel be paid by such Indemnifying Party. If an Indemnifying Party
elects not to compromise, settle or defend against a Claim, or fails to notify
an Indemnitee of its election as provided in this Section 9.3 within 30 days of
notice from the Indemnitee pursuant to Section 9.3(a), such Indemnitee may
compromise, settle or defend such Claim at the expense of such Indemnifying
Party.

          (c) If an Indemnifying Party chooses to defend any claim, the
applicable Indemnitee shall make available to such Indemnifying Party any
personnel or any books, records or other documents within its control that are
reasonably necessary or appropriate for such defense.

          (d) If the aggregate amount of any Loss shall, at any time subsequent
to payment pursuant to this Agreement, be reduced by recovery, settlement or
otherwise, the amount of such reduction, net of any expenses incurred in
connection therewith or additional Losses incurred, shall promptly be repaid by
the applicable Indemnitee to the applicable Indemnifying Party.

          (e) In the event of payment by an Indemnifying Party to any Indemnitee
in connection with any Claim, such Indemnifying Party shall be subrogated to and
shall stand in the place of such Indemnitee as to any events or circumstances in
respect of which such Indemnitee may have any right or claim relating to such
Claim. Such Indemnitee shall cooperate with such Indemnifying Party in a
reasonable manner, and, at the cost and expense of such Indemnifying Party, in
prosecuting any subrogated right or claim.

                                       25

          Section 9.4 Sole Remedy. Except in the case of fraud, the rights to
indemnification provided for in this Article IX for a breach of representations
or warranties by the Investors (in the case of indemnification pursuant to
Section 9.2(b)(i)) or the Company (in the case of indemnification pursuant to
Section 9.2(a)(i)) shall constitute the sole post-closing remedy of the Company
and the Investors respectively, for such breach, and the Company and the
Investors shall have no other liability or damages to the other party resulting
from any such breach.

                                   ARTICLE X

copies thereof by registered or certified mail, postage prepaid, or by

provided, however, that nothing herein shall affect the right of any party
hereto to serve process in any other manner permitted by Law; and

have to a trial by jury in any Proceeding directly or indirectly arising out of,

similar). No delay on the part of any party in exercising any right, power or
privilege hereunder shall operate as a waiver thereof.
