(“Company”), the Lenders (as defined in the Credit Agreement referred to below)
party hereto, and DEUTSCHE BANK TRUST COMPANY AMERICAS, as administrative agent

W I T N E S S E T H:

WHEREAS, Company, the Lenders and the Administrative Agent are parties to a
Credit Agreement, dated as of December 1, 2009 (as amended by that certain
Amendment No.1 to Credit Agreement, dated as of September 27, 2011 and as
further amended, restated, supplemented or modified to but not including the
date hereof, the “Credit Agreement”); and

WHEREAS, the parties hereto desire to make certain amendments and other
modifications to the Credit Agreement as more fully set forth herein;

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged, the parties hereto agree as follows:

SECTION 1. Amendments to Credit Agreement.

Effective on (and subject to the occurrence of) the Amendment No. 2 Effective
Date (as defined below), the Credit Agreement is hereby amended in accordance
with this Section 1.

A. The following definitions are added in the appropriate alphabetical order to
Section 1.1 of the Credit Agreement:

““2012 Sale-Leaseback” means the sale and leaseback transaction contemplated by
that certain Master Lease Agreement to be entered into by and between
CapitalSource Bank and its successors and assigns, as lessor, and Company and
its successors and permitted assigns, as lessee, in form and substance
reasonably satisfactory to the Administrative Agent, whereby the lessee will
sell to and subsequently lease from the lessor the equipment and other property
described in such Master Lease Agreement and related schedules.”

““Amendment No. 2” means Amendment No. 2 to Credit Agreement, dated as of
October 22, 2012, among Company, the Lenders party thereto and the
Administrative Agent.”

No. 2 Effective Date, 1.00% and (b) with respect to a Repricing Transaction
occurring thereafter, 0%.”

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

““Prepayment Fees” has the meaning assigned to such term in Section 2.4B(i)(b).”

““Repricing Transaction” means the prepayment, refinancing, substitution or
replacement of all or a portion of the Term Loans substantially concurrently
with the incurrence by the Company or any Subsidiary of any debt financing
having an effective interest cost or weighted average yield at the time of
incurrence thereof (with the comparative determinations to be made by the
Administrative Agent in good faith and in consultation with the Company
consistent with generally accepted financial practices, after giving effect to,
among other factors, margin, interest rate floors, upfront or similar fees or
original issue discount shared with all providers of such financing, but
excluding the effect of any arrangement, structuring, syndication or other fees
payable in connection therewith that are not shared with all providers of such
financing, and without taking into account any fluctuations in LIBOR or Base
Rate) that is less than the effective interest cost or weighted average yield
(as determined by the Administrative Agent on the same basis) of such Term Loans
at the time of incurrence thereof, including, without limitation, as may be
effected through any amendment to this Agreement relating to the interest rate
for, or weighted average yield of, such Term Loans.”

  (a) deleting the word “and” appearing at the end of clause (ii)(i) thereof;

 

  (b) adding a new clause (ii)(j) immediately after clause (ii)(i) as follows:
“any fees and expenses related to a Repricing Transaction, including any
Prepayment Fees; and” and

 

  (c) changing the heading of clause (ii)(j) from “(j)” to “(k)”.

prepayment in connection with a Waivable Voluntary Prepayment delivered by
Company may state that the prepayment date in such notice is conditioned upon
the consummation of the 2012 Sale-Leaseback, in which case such notice may be
extended or revoked by Company (by notice to the Administrative Agent on or
prior to the specified effective date) if such condition is not satisfied.”; and

 

  (c) adding a new clause “(b)” immediately after Section 2.4B(i)(a) as follows:

“(b) If the Company (x)(I) makes a voluntary prepayment of any Term Loan
pursuant to Section 2.4B(i)(a) or (II) prepays, refinances, substitutes or
replaces any Term Loan, in the case of each of clauses (x)(I) and (x)(II), in
connection with a Repricing Transaction, or (y) effects any amendment of this
Agreement resulting in a Repricing Transaction, then the Company shall pay to
the Administrative Agent, for the ratable account of each of the Lenders holding
Term Loans immediately prior to the consummation of such Repricing Transaction
(including each Lender holding Term Loans immediately prior to the consummation
of such Repricing Transaction that withholds its consent to such Repricing
Transaction and is replaced as a Terminated Lender under Section 2.10), (I) in
the case of clause (x), a prepayment premium equal to the Applicable Prepayment
Percentage of the aggregate principal amount of the Term Loans so prepaid,
refinanced, substituted or replaced and (II) in the case of clause (y), a fee
equal to the Applicable Prepayment Percentage of the aggregate principal amount
of the applicable Term Loans outstanding immediately prior to such amendment.
Such amounts shall be due and payable on the date of effectiveness of such
Repricing Transaction (as applicable, the “Prepayment Fees”).”

E. Section 2.4B(iii)(b) of the Credit Agreement is hereby amended by adding the
following new sentence at the end thereof:

“Notwithstanding the foregoing or anything in the definition of “Unreinvested
Asset Sale Proceeds” to the contrary, the Net Asset Sale Proceeds in respect of
the 2012 Sale-Leaseback shall constitute Unreinvested Asset Sale Proceeds on the
date of the consummation of such 2012 Sale-Leaseback.”

or telephonic notice (promptly confirmed in writing) given to Administrative
Agent not less than three Business Days prior to the date (the “Voluntary
Prepayment Date”) on which Company intends to make such Waivable Voluntary
Prepayment, elect to offer each Lender holding an outstanding Term Loan the
option to refuse such Lender’s Pro Rata Share of such Waivable Voluntary
Prepayment, (W) in the event Company gives such notice to Administrative Agent,
Administrative Agent will promptly notify each such Lender of the amount of such
Lender’s Pro Rata Share of such Waivable Voluntary Prepayment and such Lender’s
option to refuse such amount, (X) each such Lender may exercise such option by
giving written notice to Company and Administrative Agent of its election to do
so on or before the first Business Day (the “Cutoff Date for Waivable Voluntary
Prepayments”) prior to the Voluntary Prepayment Date, (Y) on the Voluntary
Prepayment Date, Company shall pay to Administrative Agent an amount equal to
that portion of the Waivable Voluntary Prepayment payable to those Lenders that
have elected not to exercise such option (it being understood that any Lender
which does not notify Company and Administrative Agent of its election to
exercise such option on or before the Cutoff Date for Waivable Voluntary
Prepayments shall be deemed to have elected, as of the Cutoff Date for Waivable
Voluntary Prepayments, not to exercise such option), which amount shall be
applied to prepay the Term Loans of such Lenders in accordance with this
Section 2.4B(iv)(a), and (Z) Company shall be entitled to retain that portion of
the Waivable Voluntary Prepayment otherwise payable to those Lenders that have
elected to exercise such option (such amount being a “Retained Voluntary
Prepayment”) to be used for general corporate purposes; provided, that the terms
of this sentence may, at the option of the Company, apply not only to the
Waivable Voluntary Prepayment but also to any subsequent voluntary prepayment to
be made by the Company with (x) the Retained Prepayment resulting from a
Waivable Voluntary Prepayment and/or (y) any Retained Prepayment resulting from
a Waivable Mandatory Prepayment relating to the proceeds of the 2012
Sale-Leaseback.”

Tranche of Loans and/or Commitments of the respective Terminated Lender which
will remain outstanding after giving effect to the respective replacement or
(c) to the extent such Terminated Lender is being replaced pursuant to this

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

Section 2.10 to effect a Repricing Transaction, the Prepayment Fee that would
have otherwise been payable to such Terminated Lender if such Terminated Lender
had consented to such Repricing Transaction) shall be paid in full to such
Terminated Lender concurrently with such replacement;

H. Section 7.2A of the Credit Agreement is hereby amended by:

 

  (a) deleting the word “and” appearing at the end of clause (v) thereof;

 

  (b) adding a new clause (vi) immediately after clause (v) as follows: “Liens
encumbering assets constituting “Additional Collateral” as defined in that
certain Master Lease Agreement with respect to the 2012 Sale-Leaseback (and the
Collateral Agent is hereby authorized and directed to release any liens created
pursuant to the Loan Documents on such Additional Collateral); and”; and

SECTION 2. Notices.

(i) The Company hereby notifies the Administrative Agent that, pursuant to
Sections 2.4B(iv)(a) and 2.4B(iv)(c) of the Credit Agreement (as amended
hereby), it elects to give each Lender holding an outstanding Term Loan the
option to refuse such Lender’s Pro Rata Share of the Waivable Voluntary
Prepayment and Waivable Mandatory Prepayment contemplated by Sections 3(ii) and
3(iii) of this Amendment No. 2, respectively.

(ii) Notwithstanding anything to the contrary contained in the Credit Agreement
or in this Amendment No. 2, each Lender may exercise its option to refuse such
Lender’s Pro Rata Share of the Waivable Voluntary Prepayment and Waivable
Mandatory Prepayment contemplated by clause (a) above by signing and delivering
(including by way of facsimile or other electronic transmission) to the
Administrative Agent the appropriate signature block regarding waivers in the
signature page to this Amendment No. 2. Any Lender which exercises its option to
refuse its Pro Rata Share of any Waivable Voluntary Prepayment or Waivable
Mandatory Prepayment by so noting on its signature page of this Amendment No. 2
shall be deemed to have waived any portion of such prepayments, whether as part
of the initial such offer to prepay or any subsequent offer by the Company to
prepay the amounts referred to in Sections 3(ii) and 3(iii) of this Amendment
No. 2 with amounts refused by other Lenders, the effect being that the full
amount of the prepayments required by Sections 3(ii) and 3(iii) of this
Amendment No. 2 shall be made to Lenders which have not refused such prepayments
by so noting on their signature page hereof (pro rata among such Lenders) and no
part of such prepayments shall be made to Lenders which have so refused such
prepayments.

(iii) The Company hereby notifies the Administrative Agent, pursuant to
Section 2.4(B)(i) of the Credit Agreement (as amended hereby), that it intends
to prepay the Term Loans in an aggregate principal amount equal to $45,000,000,
to be applied to the Scheduled Initial Term Loan Repayments in forward order, on
November 6, 2012. The notice provided pursuant to this clause (iii) is made
contingent on the consummation of the 2012 Sale-Leaseback. In the event that the
2012 Sale-Leaseback is not consummated on November 5, 2012, the Company shall
extend this notice so that the prepayment occurs concurrently with the
consummation of the 2012 Sale-Leaseback or rescind this notice in its entirety.

the Term Loans pursuant to Section 2.4B(iv)(a) of the Credit Agreement (as
amended hereby); provided that if any Lender declines such voluntary prepayment
pursuant to Section 2.4B(iv)(a) of the Credit Agreement (as amended hereby) then
the Company shall have re-offered such declined amounts as further voluntary
prepayments of the Term Loans until at least 95% of the prepayments contemplated
by this clause (ii) and clause (iii) below shall have been applied to prepay the
Term Loans;

(iii) Company shall have consummated the 2012 Sale-Leaseback and shall have
either (x) made a mandatory prepayment of the Term Loans pursuant to

an offer to prepay at least $30,000,000 of the Term Loans with the proceeds
generated from the 2012 Sale-Leaseback pursuant to Section 2.4B(iv)(c) of the
Credit Agreement; provided that if any Lender declines such mandatory prepayment
pursuant to Section 2.4B(iv)(c) of the Credit Agreement then the Company shall
have re-offered such declined amounts as further voluntary prepayments of the
Term Loans until at least 95% of the prepayments contemplated by this clause
(iii) and clause (ii) above shall have been applied to prepay the Term Loans;

(iv)(x) unless the Amendment No. 2 Effective Date shall occur concurrently with
the payment of such fee) and (y) for the account of the Administrative Agent all
reasonable fees, expenses and other amounts payable to the Administrative Agent
in connection with this Amendment (including, without limitation, all reasonable
legal fees and expenses of White & Case LLP, counsel to the Administrative Agent
to the extent an invoice has been provided to Company prior to the Amendment
