accordance with the terms set forth in the Specified Merger Agreement (without

and Lenders; it being understood and agreed that any reduction in the aggregate
purchase price of the Specified Merger of less than 10% of such purchase price
is hereby deemed not to be materially adverse to Agent and Lenders) and (b) all
of the transactions contemplated by the Specified Merger Agreement (including,
for the avoidance of doubt, the incurrence or assumption of any Indebtedness of
the Acquired Business to the extent that such Indebtedness is permitted under
Section 4.09 of the Specified Merger Agreement to remain outstanding immediately
following

the consummation of the Specified Merger); provided, that, each of the following
conditions precedent has been satisfied:

(a) the average daily Excess Availability for the period of thirty
(30) consecutive days immediately preceding the date of the Specified Merger

chief executive officer of Parent certifying on behalf of Parent to Agent and
Lenders that the Specified Merger complies with the foregoing conditions
precedent.

Upon the written request of Parent following the satisfaction of the conditions
precedent in clauses (a) through (d) above, Agent shall promptly confirm in
writing the satisfaction of such conditions precedent. Immediately upon the
satisfaction of the foregoing conditions precedent, the Specified Merger shall
be deemed to be a Permitted Acquisition for all purposes of the Loan Agreement
and the other Financing Agreements, without the necessity of satisfying any of
the conditions set forth in the definition of Permitted Acquisition (except that
the consideration paid for the Specified Merger shall be disregarded for the
purpose of any determination made at any time under clause (i) of the definition
of Permitted Acquisition).

No Accounts, Real Property or Equipment of the Acquired Company or its
Subsidiaries shall be Eligible Accounts, Eligible Real Property or Eligible
Equipment, respectively, until Agent has completed a field examination with
respect to the business and assets of the Acquired Company and its Subsidiaries
in accordance with Agent’s customary procedures and practices and as otherwise
required by the nature and circumstances of the business of the Acquired Company
and its Subsidiaries, the scope and results of which shall be reasonably
satisfactory to Agent (which field examination may occur before the date of the
Specified Merger), and the criteria for Eligible Accounts, Eligible Real
Property or Eligible Equipment set forth herein are satisfied with respect
thereto in accordance with the Loan Agreement or such other or additional
criteria as Agent may, at its option, establish with respect thereto in
accordance with the definitions of Eligible Accounts, Eligible Real Property and
Eligible Equipment, as applicable, and subject to such Reserves as Agent may
establish in its Permitted Discretion in connection with the assets of the
Acquired Company and its Subsidiaries to be included in the Borrowing Base in
accordance with the definition of Reserves, and in the case of Eligible Real
Property or Eligible Equipment, to the extent that it has been subject to an
appraisal that satisfies the requirements of Section 7.4 of the Loan Agreement
(which appraisal may occur before the date of the Specified Merger); provided,
that, notwithstanding anything to the contrary contained in this Amendment No. 4
or the Loan Agreement, (i) Borrowers shall reimburse Agent for the reasonable
costs and expenses of any field examination and appraisal conducted pursuant to
this paragraph and (ii) any field examination and appraisal conducted pursuant
hereto shall be in addition to any field

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

examination and appraisal contemplated by Sections 7.4 and 7.7 of the Loan
Agreement. Nothing contained in this Amendment No. 4 shall modify or otherwise
limit the obligations of Borrowers and Guarantors to comply with the terms of
Section 9.22 of the Loan Agreement.

3. Consent to Indebtedness. Notwithstanding anything set forth in the Financing
Agreements (including under Section 9.9 of the Loan Agreement), Agent and
Lenders hereby consent to Borrowers and the Guarantors incurring, creating,
assuming, becoming or being liable in any manner with respect to, or permitting
to exist, any Indebtedness constituting the New Debt or any guarantees thereof

of the Senior Secured Notes (including the payment of any applicable premiums,
make-whole payments, penalties, fees, charges, expenses and accrued interest);
provided, that, each of the following conditions precedent has been satisfied
with respect to any such New Debt (or, in the case of clause (a) below, would be
satisfied immediately after giving pro forma effect to any such New Debt and the
use of the proceeds thereof):

outstanding principal amount of the Senior Secured Notes shall not exceed
(i) $550,000,000 (plus any pay in kind interest paid thereon) or (ii) at any
time after September 15, 2012, if the Specified Merger has not been consummated

thereon);

documents, agreements and instruments evidencing or relating to the New Debt;

to the Maturity Date (including any sinking fund payments or similar type of
payments), except as permitted by clause (d) below;

(d) the terms of the New Debt shall not require Borrowers and Guarantors,
directly or indirectly, to (i) make any payments in respect of any New Debt;

Financing Agreement to the contrary, (A) Borrowers and Guarantors may make

Loans (or any Refinancing Indebtedness in respect of the Bridge Loans), to the
extent outstanding at any time on or before the first anniversary of the
Specified Merger, (1) the proceeds of issuances of equity securities issued by
Parent, (2) the proceeds of other New Debt not constituting Bridge Loans,

No. 4) other than proceeds of Indebtedness under the Loan Agreement and other
exceptions set forth therein, or (4) the proceeds of asset sales and casualty
insurance not required to prepay the Obligations or the Senior Secured Notes

Agreement defined below), or (z) in each case of clauses (x) and (y), mandatory
prepayments or mandatory offers to prepay required upon a change of control or
payments required upon the acceleration of the New Debt (or any Refinancing
Indebtedness in respect of the New Debt) upon the occurrence and during the
continuance of an event of default under the documents governing the New Debt
(or any Refinancing Indebtedness in respect of the New Debt), and (E) Borrowers
and Guarantors may make payments in respect of the New Debt (or any Refinancing

writing the satisfaction of such conditions precedent.

4. Consent to Liens. Notwithstanding anything to the contrary set forth in the
Financing Agreements (including Section 9.8 of the Loan Agreement), Agent and
Lenders hereby consent to the creation, incurrence, assumption and existence of
any security interest, mortgage, pledge, lien, charge or other encumbrance of
any nature whatsoever securing the Indebtedness constituting the New Debt (or
any Refinancing Indebtedness in respect of the New Debt) and the guarantees
thereof and the filing and remaining in effect of any financing statement or
other similar notice of any security interest with respect thereto; provided,
that, such security interests and liens shall be subject and subordinate to the
security interests and liens of Agent pursuant to the Intercreditor Agreement or
another intercreditor agreement (collectively, the “New Debt Intercreditor
Agreement”) reasonably satisfactory to Agent (it being agreed that (a) an
intercreditor agreement that is substantially identical to the Intercreditor

of the New Debt and any amounts required to be maintained therein to pay
