for the Interest Period(s) selected, (B) is to be continued in whole
or in part as one or more Base Rate Zion L/C Loans, or (C) is to be repaid

for Zion L/C Loan Eurodollar Basis or Request for Term Loan Eurodollar Basis,
or telephonic notice followed immediately by a Request for Loan, Request for
Zion L/C Loan Eurodollar Basis or Request for Term Loan Eurodollar Basis; provided,
however, that EnergySolutions’ failure to confirm any telephonic notice
with a Request for Loan, Request for Zion L/C Loan Eurodollar Basis or Request
for Term Loan Eurodollar Basis shall not invalidate any notice so given.  The Administrative Agent, whose determination
shall be conclusive absent manifest error, shall determine the available
Eurodollar Basis and shall notify EnergySolutions of such Eurodollar
Basis.  EnergySolutions shall promptly notify
the Administrative Agent by telephone or telecopy, and shall immediately
confirm any such telephonic notice in writing, of its selection of a Eurodollar
Basis and Interest Period for such Loan; provided, however, that
EnergySolutions’ failure to confirm any such telephonic notice in writing shall
not invalidate any notice so given.

 

(ii)     Repayments and
Reborrowings of Eurodollar Revolving Loans. 
Upon at least one (1), with respect to items (B) and (C) of
this sentence, or three (3), with respect to item (A) of this sentence,

then reborrowed in whole or in part as one or more Eurodollar Revolving Loans
for the Interest Period(s) selected, (B) is to be repaid and then
reborrowed in whole or in part as one or more Base Rate Revolving Loans, or (C) is

40

 

(d)           Notification of
Lenders.  Upon receipt of a Request
for Loan, or a notice from EnergySolutions with respect to a selection of an
Interest Period for a Revolving Loan, or a notice from EnergySolutions with
respect to any outstanding Revolving Loan prior to the Payment Date for such Revolving
Loan, the Administrative Agent shall promptly notify each Lender by telephone
or telecopy of the contents thereof and the amount of such Lender’s portion of
the related Revolving Loan.  Each Lender
shall, not later than 2:30 p.m. (New York time) on the date of borrowing
specified in such notice, make available to the Administrative Agent at the
Administrative Agent’s Account, or at such account as the Administrative Agent
shall designate, the amount of its portion of any Revolving Loan which
represents an additional borrowing hereunder in immediately available funds.

 

(e)           Disbursement.

 

(i)      Prior to 3:00 p.m. (New
York time) on the date of the making of a Revolving Loan hereunder, the
Administrative Agent shall, subject to the satisfaction of any applicable conditions
set forth in Article 3 hereof, disburse
the amounts made available to it by the Lenders in like funds by (A) transferring
the amounts so made available by wire transfer pursuant to EnergySolutions’
instructions, or (B) in the absence of such instructions, crediting the
amounts so made available to the account of EnergySolutions maintained with the
Administrative Agent; provided, however, that the Administrative
Agent shall first make the applicable portion of such funds equal to the
aggregate principal amount of any Letter of Credit Loans made by the Revolving
Issuing Bank and by any other Revolving Lender and outstanding on the date of
such Revolving Loan, plus interest accrued and unpaid thereon to and as of such
date, available to the Revolving Issuing Bank and such other Revolving Lender
for repayment of such Letter of Credit Loans.

 

(ii)     Unless the Administrative
Agent shall have received notice from a Lender prior to 2:30 p.m. (New
York time) on the date of any Loan that such Lender will not make available to
the Administrative Agent such Lender’s ratable portion of such Loan, the Administrative
Agent may assume that such Lender has made or will make such portion available
to the Administrative Agent on the date of such Loan and the Administrative
Agent may in its sole discretion and in reliance upon such assumption, make
available to EnergySolutions on such date a corresponding amount.  If and to the extent the Lender does not make
such ratable portion available to the Administrative Agent, such Lender agrees
to repay to the Administrative Agent on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to EnergySolutions until the date such amount is repaid to the Administrative
Agent, at the Federal Funds Rate for the first three (3) days and
thereafter at the Federal Funds Rate plus one percent (1%).

 

(iii)    If such Lender shall repay to
the Administrative Agent such corresponding amount, such amount so repaid shall
constitute such Lender’s portion of the applicable Loan for purposes of this
Agreement.  If such Lender does not repay
such corresponding amount immediately upon the Administrative Agent’s demand
therefor, the Administrative Agent shall notify EnergySolutions and EnergySolutions
shall immediately pay such corresponding amount to the Administrative Agent,
together with interest thereon.  The
failure of any Lender to fund its portion of any Loan shall not relieve any
other Lender of its obligation hereunder to fund its respective portion of the
Loan on the date of such borrowing, but no Lender shall be responsible for any
such failure of any other Lender.

 

(iv)    In the event that, at any time
when EnergySolutions is not in Default and has satisfied all applicable
conditions set forth in Article 3
hereof, a Lender for any reason fails, refuses, or has given notice to the
Administrative Agent and/or EnergySolutions that it refuses, to fund its portion
of a Loan or, in accordance with Section 2.2(f)(ii) or
2A.1(a)(ii) below, a disbursed
amount (a “Defaulting Lender”), then, until such time as such Defaulting
Lender has funded its portion of such Loan, or all other Lenders 

 

41

 

have received payment in full (whether by
repayment or prepayment) of the principal and interest due in respect of such
Loan, such Defaulting Lender shall not have the right (i) to vote
regarding any issue on which voting is required or advisable under this
Agreement or any other Loan Document, and such Lender’s Unused Revolving Commitment
and interest in any Loans or Revolving Letters of Credit shall not be counted
as outstanding for purposes of determining “Majority Lenders” hereunder or (ii) to
receive payments of (A) principal, interest or fees from EnergySolutions
in respect of its unfunded portion of Loans, (B) any commitment fee in
respect of its Revolving Commitment or (C) any portion of Revolving Letter
of Credit fees or interests or amounts in respect of any Letter of Credit
Loans.  In addition to the foregoing, and
notwithstanding Section 2.1(d), if any Lender
shall become a Defaulting Lender, the Revolving Letter of Credit Commitment
shall be reduced by an amount equal to such Defaulting Lender’s Pro Rata Share
of the Revolving Letter of Credit Commitment unless and until arrangements
reasonably satisfactory to the Revolving Issuing Bank have been entered into
(the Revolving Issuing Bank having made a good faith effort to enter into such
arrangements) to eliminate the Revolving Issuing Bank’s risk with respect to
the Defaulting Lender’s Pro Rata Share of the Revolving Letter of Credit
Commitment, including cash collateralizing the Revolving Issuing Bank’s
Revolving Letter of Credit Commitment with respect to such Defaulting Lender’s
Pro Rata Share.  The provisions of this Section 2.2(e)(iv) are not in lieu of any other
claim EnergySolutions may have against such Defaulting Lender.

 

(f)            Issuance
of and Drawings and Reimbursement Under Letters of Credit.

 

This Section 2.2(f) shall not be applicable to the Zion
Letters of Credit, which are governed by Article 2A.

 

(i)      Request for Issuance.  Each Letter of Credit shall be issued upon
notice, given not later than 12:30 p.m. (New York time) on the fifth
Business Day prior to the date of the proposed issuance of such Letter of Credit,
by EnergySolutions to the applicable Issuing Bank, which shall give to the Administrative
Agent and each Revolving Lender (in the case of a request for a Revolving
Letter of Credit) or each Term L/C Facility Lender (in the case of a request
for a Term L/C Facility Letter of Credit) prompt notice thereof by telecopier
or electronic communication.  Each such
notice of issuance of a Letter of Credit (a “Notice of Issuance”) shall
be by telephone, confirmed immediately in writing, or telecopier or electronic
communication, specifying therein the requested (A) date of such issuance
(which shall be a Business Day), (B) Available Amount of such Letter of
Credit (which amount shall not be less than $100,000), (C) expiration date
of such Letter of Credit, (D) name and address of the beneficiary of such
Letter of Credit and (E) form of such Letter of Credit, and shall be
accompanied by such application and agreement for Letter of Credit as the
Issuing Bank may specify to EnergySolutions for use in connection with such
requested Letter of Credit (a “Revolving Letter of Credit Agreement” or
a “Term L/C Facility Letter of Credit Agreement,” as applicable).  If (x) the requested form of such Letter
of Credit is acceptable to the applicable Issuing Bank in its sole discretion, (y) as
of the requested date of issuance, the requirements of Section 2.1(c) or
2.1(f) hereof have been satisfied
as to such Letter of Credit, and (z) the applicable Issuing Bank has not
received notice of objection to such issuance from the Majority Lenders, the
applicable Issuing Bank will, upon fulfillment of the applicable conditions set
forth in Article 3, make such Letter of
Credit available to EnergySolutions at its office referred to in Section 11.1 or as otherwise agreed with EnergySolutions
in connection with such issuance.  In the
event and to the extent that the provisions of any Letter of Credit Agreement
shall conflict with this Agreement, the provisions of this Agreement shall
govern.

 

(ii)     Participations in
Revolving Letter of Credits.  Upon
the issuance of a Revolving Letter of Credit by the Revolving Issuing Bank, the
Revolving Issuing Bank shall be deemed, without further action by any party
hereto, to have sold to each Revolving Lender, and each such Revolving Lender
shall be deemed, without further action by any party hereto, to have purchased
from the Revolving Issuing Bank, 

 

42

 

a participation in such Revolving Letter of
Credit in an amount for each Revolving Lender equal to the Dollar Equivalent of
such Lender’s Pro Rata Share of the Available Amount of such Revolving Letter
of Credit, effective upon the issuance of such Revolving Letter of Credit.  In consideration and in furtherance of the
foregoing, each Revolving Lender hereby absolutely and unconditionally agrees
to pay such Lender’s Pro Rata Share of each L/C Disbursement made by the
Revolving Issuing Bank and not reimbursed by EnergySolutions forthwith on the
date due as provided in Section 2.4(c) (or
which has been so reimbursed but must be returned or restored by the Revolving
Issuing Bank because of the occurrence of an event specified in Section 8.1(f) or (g) or
otherwise) by making available to the Administrative Agent for the account of
the Revolving Issuing Bank by deposit to the Administrative Agent’s Account, in
same day funds, an amount equal to the Dollar Equivalent of such Lender’s Pro
Rata Share of such L/C Disbursement. 
Each Revolving Lender acknowledges and agrees that its obligation to
acquire participations pursuant to this Section 2.2(f)(ii) in
respect of Revolving Letters of Credit is absolute and unconditional and shall
not be affected by any circumstance whatsoever, including the occurrence and
continuance of a Default or an Event of Default or the termination of the
Commitments, and that each such payment shall be made without any offset,
abatement, withholding or reduction whatsoever. 
If and to the extent that any Revolving Lender shall not have so made
the amount of such L/C Disbursement available to the Administrative Agent, such
Revolving Lender agrees to pay to the Administrative Agent forthwith on demand
such amount together with interest thereon, for each day from the date such L/C
Disbursement is due pursuant to Section 2.4(c) until
the date such amount is paid to the Administrative Agent, at the Federal Funds
Rate for its account or the account of the Revolving Issuing Bank, as applicable.  If such Lender shall pay to the
Administrative Agent such amount for the account of the Revolving Issuing Bank
on any Business Day, such amount so paid in respect of principal shall
constitute a Letter of Credit Loan made by such Lender on such Business Day for
purposes of this Agreement, and the outstanding principal amount of the Letter
of Credit Loan made by the Revolving Issuing Bank shall be reduced by such
amount on such Business Day.

 

(iii)    Participations in Term L/C
Facility Letters of Credit.  Upon
receipt from the beneficiary of any Term L/C Facility Letter of Credit of any
notice of a drawing under such Letter of Credit, the relevant Term L/C Issuing
Bank shall promptly notify EnergySolutions and the Administrative Agent thereof
(which may be telephonic, promptly confirmed by telecopy).  EnergySolutions shall be required to reimburse
such Term L/C Facility Issuing Bank through the Administrative Agent in an
amount equal to the Dollar Equivalent of such drawing not later than 1:00 p.m.
(eastern time) on the Honor Date, if EnergySolutions shall have received such
notice prior to 11:00 a.m. (eastern time) on such date, or, if such notice
has not been received by EnergySolutions prior to such time on such date, then
not later than 1:00 p.m. (eastern time) on the next Business Day; provided
that unless EnergySolutions shall reimburse such Term L/C Issuing Bank by 1:00 p.m.
(eastern time) on the same day on which such drawing is made, the unpaid amount
(such amounts, including accrued interest, the “Term L/C Facility
Unreimbursed Amount”) thereof shall bear interest at a rate per annum equal
to the Base Rate plus the Applicable Margin, for each day commencing on the
date the drawing is made until the date that EnergySolutions pays the Administrative
Agent for the account of such Term L/C Facility Issuing Bank the Dollar
Equivalent of the amount of such drawing. 
If EnergySolutions does not so reimburse the relevant Term L/C Issuing
Bank at or prior to the time for payment specified above in respect of such
drawing under such Term L/C Facility Letter of Credit, the Administrative Agent
may promptly cause the amounts on deposit in the Term L/C Facility Collateral
Account to be applied to repay in full or in part such amounts and the Term L/C
Facility shall be automatically but not permanently reduced by the Term L/C
Facility Unreimbursed Amount in accordance with Section 2.2(f)(vii).  EnergySolutions may from time to time cause
additional funds to be deposited and held in the Term L/C Facility Collateral
Account to replace any funds applied by the Administrative Agent pursuant to
the preceding sentence to repay a Term L/C Facility Unreimbursed Amount.  All funds deposited and held in the Term L/C
Facility Collateral Account pursuant to the 

 

43

 

foregoing sentence shall increase the Term
L/C Facility Available Amount by an amount equal to the Dollar Equivalent of
the funds deposited.

 

(iv)    Drawing and Reimbursement.  The payment by the Revolving Issuing Bank of
a draft drawn under any Revolving Letter of Credit shall constitute for all
purposes of this Agreement the making by the Revolving Issuing Bank of a Letter
of Credit Loan, which shall be a Base Rate Option Loan, in the Dollar Equivalent
of the amount of such draft.

 

(v)     Letter of Credit Reports.  The Issuing Banks shall furnish (A) to
the Administrative Agent on or about the first Business Day of each week a
written report summarizing issuance and expiration dates of Letters of Credit
issued during the previous week and drawings during such week under all Letters
of Credit, (B) to each Revolving Lender and Term L/C Facility Lender on or
about the first Business Day of each month a written report summarizing
issuance and expiration dates of Letters of Credit issued during the preceding
month and drawings during such month under all Letters of Credit and (C) to
the Administrative Agent and each Revolving Lender on the first Business Day of
each calendar quarter a written report setting forth the average daily
aggregate Available Amount during the preceding calendar quarter of all Revolving
Letters of Credit.

 

(vi)    Failure to Make Letter of
Credit Loans.  The failure of any
Lender to make the Letter of Credit Loan to be made by it on the date specified
in Section 2.4(c) shall not
relieve any other Lender of its obligation hereunder to make its Letter of
Credit Loan on such date, but no Lender shall be responsible for the failure of
any other Lender to make the Letter of Credit Loan to be made by such other
Lender on such date.

 

(vii)   Term
L/C Facility Collateral Account.

 

(A)          On or prior to the Third
Amended and Restated Credit Agreement Effective Date, the Borrower shall
establish the Term L/C Facility Collateral Account for the purpose of cash
collateralizing EnergySolutions’ obligations to the Term L/C Issuing Bank in
respect of the Term L/C Facility Letters of Credit.  On the Third Amended and Restated Credit
Agreement Effective Date the proceeds of the Term L/C Facility Loans shall be
deposited in the Term L/C Facility Collateral Account pursuant to Section 2.1(c). 
EnergySolutions agrees that at all time thereafter, and shall
immediately cause additional funds to be deposited and held in the Term L/C
Facility Collateral Account from time to time in order that, the Term L/C
Facility Collateral Account Balance shall at least equal the Term L/C Facility
Available Amount plus the Dollar Equivalent of the aggregate amount of Term L/C
Facility Unreimbursed Amounts.  EnergySolutions
hereby grants to the Collateral Agent, for the benefit of the Term L/C Issuing
Bank, a security interest in the Term L/C Facility Collateral Account and all
cash and balances therein and all proceeds of the foregoing, as security for
the Term L/C Facility Obligations (and, in addition, grants a security interest
therein, for the benefit of the Secured Parties as collateral security for the
Secured Obligations, provided that amounts on deposit in the Term L/C
Facility Collateral Account shall be applied, first, to repay Term L/C Facility
Obligations and, then, all other Secured Obligations).  Except as expressly provided herein or in any
other Loan Document, no Person shall have the right to make any withdrawal from
the Term L/C Facility Collateral Account or to exercise any right or power with
respect thereto; provided that at any time EnergySolutions shall fail to
reimburse any Term L/C Facility Issuing Bank for any Term L/C Facility
Unreimbursed Amounts in accordance with the terms of Section 2.2(f)(iii),
EnergySolutions hereby absolutely, unconditionally and irrevocably agrees that
the Collateral Agent shall be entitled to instruct the depositary bank (the “Depositary
Bank”) of the Term L/C Facility 

 

44

 

Collateral
Account to withdraw therefrom and pay to the Administrative Agent for account
of such Term L/C Facility Issuing Bank amounts equal to such Term L/C Facility
Unreimbursed Amounts.

 

(B)           The Administrative
Agent shall maintain records enabling it to determine at any time the amount of
each Lender’s Term L/C Facility Loan; the evidence of such Lender’s Term L/C
Facility Loan is herein referred to as such Lender’s “Term L/C Facility
Collateral Sub-Account”).  The
Administrative Agent shall establish such additional Term L/C Facility
Collateral Sub-Accounts for assignee Lenders as shall be required pursuant to Section 11.5.  No
person (other than the Administrative Agent or any of its sub agents) shall
have the right to make any withdrawals from the Term L/C Facility Collateral Account
or exercise any other right or power with respect thereto, except as expressly
provided herein.

 

(C)           Concurrently with the
effectiveness of any assignment by any Term L/C Facility Lender of all or any
portion of its Term L/C Facility Loan, the corresponding portion of the
assignor’s Term L/C Facility Collateral Sub-Account shall be transferred from
the assignor’s Term L/C Facility Collateral Sub-Account to the assignee’s Term
L/C Facility Collateral Sub-Account in accordance with Section 11.5
and, if required by Section 11.5,
the Administrative Agent shall close such assignor’s Term L/C Facility  Collateral Sub-Account.

 

(D)          Upon the reduction of
the Term L/C Facility Available Amount and the Term L/C Facility Letter of
Credit Outstandings to zero pursuant to Section 2.7,
all amounts remaining in the Term L/C Facility Collateral Account shall be used
to repay any outstanding principal, interest and any other Obligations arising
under the Term L/C Facility Loans.  To
the extent the outstanding principal, interest and any other Obligations
arising under the Term L/C Facility Loans have been satisfied, any amounts remaining
in the Term L/C Facility Collateral Account shall be returned to EnergySolutions.

 

(E)           The Administrative
Agent shall invest, or cause to be invested, the Term L/C Facility Collateral
Account Balance so as to earn for the account of EnergySolutions a return thereon
(the “Term L/C Facility Collateral Return”) for each day at a rate per
annum equal to (i) the one month LIBOR rate as determined by the
Administrative Agent on such day (or if such day was not a Business Day, the
first Business Day immediately preceding such day) based on rates for deposits
in dollars (as set forth by Bloomberg L.P.-page BTMM or any other
comparable publicly available service as may be selected by the Administrative
Agent) (the “Benchmark LIBO Rate”) minus (ii) 0.15% per annum
(based on a 365/366 day year).  The
Benchmark LIBO Rate will be reset monthly. 
The Term L/C Facility Collateral Return accrued through and including
the last day of each Interest Period shall be payable by the Administrative
Agent to EnergySolutions on each day on which interest is required to be paid
with respect to all or any portion of the Term L/C Facility Loans pursuant to Section 2.3(g). 
No Person other than the Administrative Agent shall have any obligation
under or in respect of this clause.

 

(F)           [Reserved].

 

(G)           If the Term L/C
Facility Issuing Bank is enjoined from taking any action referred to in clause (ii) of
Section 2.4(d), or if the Term L/C
Facility Issuing Bank reasonably determines that, by operation of law, it may
reasonably be precluded from taking any such action, or if any Loan Party or
Term L/C Facility Lender challenges in any legal proceeding any of the
acknowledgements, agreements or characterizations set forth in any of clause (a) of
this Section 2.2(f)(vii), then, in any
such case (and so long as such event or condition shall be continuing), and
notwithstanding anything contained herein to the

 

45

 

contrary, the Term L/C Facility Issuing Bank shall not be required to
issue, renew or extend any Term L/C Facility Letter of Credit.

 

(H)          [Reserved].

 

(I)            Applicability
of ISP98. Unless otherwise expressly agreed by the applicable Issuing Bank
and EnergySolutions when a Letter of Credit is issued, the rules of the “International
Standby Practices 1998” published by the Institute of International Banking Law &
Practice (or such later version thereof as may be in effect at the time of
issuance) shall apply to each Letter of Credit.

 

Section 2.3                                      Interest.

 

(a)           On
Base Rate Option Loans. Interest on each Base Rate Option Loan shall be
computed on the basis of a year of 365/366 days for the actual number of days
elapsed and shall be payable at the Base Rate Basis for such Base Rate Option
Loan, in arrears on the applicable Payment Date for the period through the date
immediately preceding such Payment Date. Interest on Base Rate Option Loans
then outstanding shall also be due and payable on the Revolving Maturity Date,
the Zion L/C Facility Letter of Credit Maturity Date or the Term Loan Maturity
Date, as applicable, with respect to Revolving Loans, Zion L/C Loans and Term
Loans.

 

(b)           On
Eurodollar Option Loans. Interest on each Eurodollar Option Loan shall be
computed on the basis of a 360-day year for the actual number of days elapsed
and shall be payable at the Eurodollar Basis for such Eurodollar Option Loan,
in arrears on the applicable Payment Date for the period through the day
immediately preceding such Payment Date, and, in addition, if the Interest
Period for a Eurodollar Option Loan exceeds three (3) months, interest on
such Eurodollar Option Loan shall also be due and payable in arrears on every
three-month anniversary of the first day of such Interest Period. Interest on
Eurodollar Option Loans then outstanding shall also be due and payable on the
Revolving Maturity Date, the Zion L/C Maturity Date or the Term Loan Maturity
Date, as applicable, with respect to Revolving Loans, Zion L/C Loans and Term
Loans.

 

(c)           Interest
if No Notice of Selection of Interest Rate Basis. With respect to any Loan,
if EnergySolutions fails to give the Administrative Agent timely notice of its
selection of a Eurodollar Basis, or if for any reason a determination of a
Eurodollar Basis for any Loan is not timely concluded, the Base Rate Basis
shall apply to such Loan.

 

(d)           Interest
upon Default. Immediately upon the occurrence of an Event of Default hereunder,
all overdue principal in respect of the Loans, together with accrued and unpaid
overdue interest, premium and other unpaid sums, shall bear interest at the
Default Rate. Such interest shall be payable on demand and shall accrue until
the earliest of (a) waiver or cure (to the satisfaction of the Lenders required
under Section 11.12 hereof to waive or
cure) of such Event of Default, or (b) agreement by the Majority Lenders
to rescind the charging of interest at the Default Rate, or (c) payment in
full of the Obligations.

 

(e)           Eurodollar
Option Loans. At no time may the number of outstanding Eurodollar Option
Loans exceed eight (8).

 

(f)            Applicable
Margin. With respect to any Loan hereunder, the Applicable Margin shall be (i) with
respect to any Term Loan, (x) 2.50% for Eurodollar Term Loans (or 2.00%
when the Leverage Ratio as of the most recently completed fiscal quarter is
less than 2.0 to 1.0) and (y) 1.25% for Base Rate Term Loans (or 1.00%
when the Leverage Ratio as of the most recently completed fiscal quarter is
less than 2.0 to 1.0), (ii) with respect to any Revolving Loan or Zion L/C
Loan, (x) 2.50% for Eurodollar 

 

46

 

Option Loans
and (y) 1.25% for Base Rate Options Loans and (iii) with respect to
any Term L/C Facility Loan and the Term L/C Facility Unreimbursed Amount, 2.50%
(or 2.00% when the Leverage Ratio as of the most recently completed fiscal quarter
is less than 2.0 to 1.0)

 

(g)           Term
L/C Facility Loans. Upon the transfer of the aggregate amount of the
Synthetic Deposit Account into the Term L/C Facility Collateral Account on the
Third Amended and Restated Effective Date pursuant to Section 2.1(c) hereof,
the Term L/C Facility Loans shall accrue interest at a rate per annum equal to
the sum of the Eurodollar Rate for the relevant Interest Period plus the
Applicable Margin. All Term L/C Facility Loans shall accrue interest at all
times that they are on deposit in the Term L/C Facility Collateral Account. Interest
accrued on each Term L/C Facility Loan shall be payable, without
duplication:  (a) on the Term L/C
Facility Letter of Credit Maturity Date, (b) on the date of any repayment
of the Term L/C Facility Loans made pursuant to Section 2.7
and (c) on the last day of each Interest Period.

(a)           Any
unpaid principal and interest of the Revolving Loans and any other outstanding
Obligations under the Revolving Commitment shall be due and payable in full on
the Revolving Maturity Date. Any unpaid principal and interest of the Term L/C
Facility Loans and any other outstanding Obligations arising under the Term L/C
Facility Loans shall be due and payable in full on the Term L/C Facility Letter
of Credit Maturity Date.

 

(b)           EnergySolutions
shall repay to the Administrative Agent for the account of the Zion Issuing
Banks and each other Zion Lender that has made a Zion L/C Loan on the Zion L/C
Maturity Date any unpaid principal and interest of each Zion L/C Loan made by
each of them.

of the Term Loans as of the opening of business on September 30, 2006
multiplied by 0.25%. On June 7, 2013, the outstanding principal balance of
the Term Loans, if any, shall be repaid in full. Notwithstanding anything to

Section 2.6                                      Optional
Prepayments and Application of Prepayments.

 

(a)           Optional
Prepayment of Loans. Subject to Section 2.6(b),
the principal amount of any Base Rate Option Loan may be prepaid in full or in
part at any time, without penalty or premium and without regard to the Payment
Date for such Loan, upon not less than one (1) Business Day’s prior written
notice to the Administrative Agent of such prepayment. Subject to Section 2.6(b) and Section 2.11,
Eurodollar Option Loans may be prepaid prior to the due date thereof, upon not
less than three (3) Business Days’ prior written notice to the Administrative
Agent. Partial prepayments shall be in a principal amount of not less than
$1,000,000 and in an integral multiple of $500,000. A notice of prepayment
shall be irrevocable.

 

49

 

(b)           Application
of Prepayment. Each prepayment of the Term Loans shall be applied (i) first,
in direct order of maturities, to the next four scheduled principal repayment installments
of the Term Facility and (ii) second, to the other principal repayment
installments of the Term Facility on a pro rata basis among the Term Lenders. Any
prepayment of Zion L/C Loans shall be applied (i) first, to prepayment of
the Zion L/C Loans then outstanding until such Loans are paid in full, and (ii) second,
to be deposited in the L/C Collateral Account to cash collateralize the
aggregate Available Amount of the Zion Letters of Credit then outstanding. Any
prepayment of Revolving Loans shall be applied (A) first, to prepayment of
the Letter of Credit Loans then outstanding until such Loans are paid in full, (B) second,
to prepayment of Revolving Loans then outstanding until such Loans are paid in
full and (C) third, to be deposited in the L/C Collateral Account to cash
collateralize the aggregate Available Amount of the Revolving Letters of Credit
then outstanding. Any prepayment of the Term Facility, the Term L/C Facility or
the Zion L/C Facility may not be reborrowed. Any prepayment of Revolving Loans
pursuant to this Section 2.6 shall not reduce
the Revolving Commitment. The prepayment of any principal amount of Loans shall
be made with accrued interest to the date of such prepayment on the aggregate
principal amount prepaid and EnergySolutions shall reimburse the Lenders and
the Administrative Agent, on demand, for any loss or out-of-pocket expense
incurred by any Lender Party or the Administrative Agent in connection with
such prepayment, as set forth in Section 2.11
hereof. Any prepayment under this Agreement shall not affect EnergySolutions’
obligation to continue making payments under any Secured Hedge Agreements,
which shall remain in full force and effect notwithstanding such prepayment,
subject to the terms of such Secured Hedge Agreements.

 

Section 2.7                                      Term
L/C Facility Loan Repayments.

 

From time to time on any Business Day, EnergySolutions may cause the
Term L/C Facility Loans to be repaid ratably to the Term L/C Facility Lenders; provided
that (A) all such voluntary repayments shall require at least one but no
more than five (5) Business Days’ prior telephonic notice (promptly confirmed
in writing or via e-mail communication)(1) to the
Administrative Agent; (B) all such voluntary partial repayments shall be
in an aggregate minimum amount of $1,000,000 and an integral multiple of
$500,000, and (C) such repayments shall be accompanied by reimbursement
for losses or out-of-pocket expenses in accordance with Section 2.11, if
any.

 

Section 2.8                                      Mandatory
Prepayments.

 

(a)           In
addition to the scheduled repayments provided for in Section 2.4
hereof, EnergySolutions shall prepay the Term Loans in an amount equal to 100%
of the Net Proceeds (w) from any sale or disposition by Holdco, Parent or
any of their Subsidiaries of any interest in any Loan Party (other than from a
sale to another Loan Party), (x) except as set forth below, from any
Permitted Asset Sales (other than any Excluded Asset Sales) and (y) except
as set forth in Section 5.5(e) hereof,
received as a result of a casualty or condemnation. Such amount shall be
applied on the third Business Day following receipt thereof by EnergySolutions or
the affected Subsidiary in accordance with Section 2.6(b).
EnergySolutions shall also prepay the Term Loans, with application thereto in
accordance with Section 2.6(b), in respective
amounts equal to the after-Tax amount of any refund, purchase price adjustment,
claim or credit arising under any agreement governing or relating to any
acquisition of any assets or business. Notwithstanding the foregoing, with
respect to any Net Proceeds realized or received with respect to any Permitted
Asset Sales (other than any Excluded Asset Sales), at the option of EnergySolutions,
and so long as no

 

(1)           [Subject to confirm by
Citi operations.]

 

50

 

Default or
Event of Default shall have occurred and be continuing, EnergySolutions may reinvest
all or any portion of such Net Proceeds in assets used or useful for its
business within three hundred sixty-five (365) days following receipt of such
Net Proceeds; provided, however, that (i) if the property
subject to such asset sale constituted Collateral under the Security Documents,
then any capital assets purchased with the Net Proceeds thereof pursuant to
this subsection shall be mortgaged or pledged, as the case may be, to the
Administrative Agent, for the benefit of the Secured Parties and (ii) if
any Net Proceeds are no longer intended to be so reinvested at any time after
delivery of a notice of reinvestment election, an amount equal to any such Net
Proceeds shall be immediately applied to the prepayment of the Loans in accordance
with Section 2.6(b). For the purposes
of calculating the mandatory prepayment required by this Section 2.8(a),
“Net Proceeds” shall exclude all Net Proceeds received by Duratek and its
Subsidiaries; provided that “Duratek and its Subsidiaries”
shall not include EnergySolutions and its Subsidiaries if EnergySolutions is a
Subsidiary of Duratek.

 

(b)           In
addition to the scheduled repayments provided for in Section 2.4
hereof, EnergySolutions shall prepay the Term Loans in an amount
equal to one hundred percent (100%) of the Net Proceeds received after the
Second Amendment Effective Date from any Indebtedness for Money Borrowed incurred
by Holdco, EnergySolutions, Parent or any of their Subsidiaries, except for
Indebtedness for Money Borrowed (i) permitted by Section 7.1
hereof or (ii) incurred in connection with any Permitted
Investments or Permitted Acquisitions permitted under Section 7.6
hereof (including any Indebtedness assumed by EnergySolutions or the
Subsidiaries in connection with any such Permitted Investment or Permitted
Acquisition), to the extent that upon consummation of any such Permitted
Investment or Permitted Acquisition such Net Proceeds were invested in, or used
to acquire, such Permitted Investment
or Permitted Acquisition. Such amount shall be applied on the third Business
Day following receipt thereof by EnergySolutions, Parent or the affected
Subsidiary in accordance with Section 2.6(b).
For the purposes of calculating the mandatory prepayment required by this Section 2.8(b), “Net Proceeds” shall exclude all Net
Proceeds received from any Indebtedness for Money Borrowed incurred by Duratek
and its Subsidiaries; provided that “Duratek and its Subsidiaries”
shall not include EnergySolutions and its Subsidiaries if EnergySolutions is a
Subsidiary of Duratek.

 

(c)           In addition to the
scheduled repayments provided for in Section 2.4 hereof,
for each fiscal quarter during the term hereof (commencing with the fiscal
quarter ended September 30, 2006), on or prior to the fifth Business Day
following delivery of the financial statements required by Sections 6.1
and 6.2 hereof for the most recently
completed fiscal quarter, (x) so long as the Leverage Ratio as of the end
of the most recently completed fiscal quarter is equal to or greater than 3.0
to 1.0, EnergySolutions shall prepay the Term Loans in an amount equal to the
difference between (i) fifty percent (50%) of Excess Cash Flow for the
most recently completed fiscal quarter and (ii) an amount equal to the
optional prepayments made pursuant to Section 2.6 in
such fiscal period, (y) if the Leverage Ratio as of the end of the most
recently completed fiscal quarter is less than 3.0 to 1.0 and greater than 1.0
to 1.0, EnergySolutions shall prepay the Term Loans in an amount equal to the
difference between (i) twenty-five percent (25%) of Excess Cash Flow for
the most recently completed fiscal quarter and (ii) an amount equal to the
optional prepayments made pursuant to Section 2.6 in
such fiscal period and (z) if the Leverage Ratio as of the end of the most recently completed fiscal quarter is less
than or equal to 1.0 to 1.0, EnergySolutions shall not be required prepay the
Term Loans.

 

(d)           Any
prepayment pursuant to this Section 2.8
shall be made in the manner set forth in Section 2.6(b).

 

51

 

Section 2.9                                      Evidence
of Debt.

 

(a)           The
Loans shall be repayable in accordance with the terms and provisions set forth
herein. Upon the request of any Lender, Notes shall be issued by
EnergySolutions and payable to the order of such Lender reflecting such Lender’s
Revolving Commitment, Zion Commitment and Term Loans. The Notes issued by
EnergySolutions to the Lenders shall be duly executed and delivered by one or
more Authorized Signatories.

 

(b)           Each
Lender Party shall maintain in accordance with its usual practice an account or
accounts evidencing the indebtedness of EnergySolutions to such Lender Party
resulting from each Loan owing to such Lender Party from time to time,
including the amounts of principal and interest payable and paid to such Lender
Party from time to time hereunder.

 

(c)           The
Register maintained by the Administrative Agent pursuant to Section 11.5(c) shall include a control account,
and a subsidiary account for each Lender Party, in which accounts (taken together)
shall be recorded (i) the date and amount of each Loan made hereunder, the
Type of such Loan and, if appropriate, the Interest Period applicable thereto, (ii) the
terms of each Assignment and Acceptance delivered to and accepted by it, (iii) the
amount of any principal or interest due and payable or to become due and
payable from EnergySolutions to each Lender Party hereunder, (iv) the
amount of any sum received by the Administrative Agent from EnergySolutions
hereunder and each Lender Party’s share thereof and (v) the amount of such
Lender Party’s Term L/C Facility Loans.

 

(d)           Entries
made in good faith by the Administrative Agent in the Register pursuant to Section 2.9(c) above, and by each Lender Party in
its account or accounts pursuant to Section 2.9(b) above,
shall be prima facie evidence of the amount of principal and interest due and
payable or to become due and payable from EnergySolutions to, in the case of
the Register, each Lender Party and, in the case of such account or accounts,
such Lender Party, under this Agreement, absent manifest error; provided,
however, that the failure of the Administrative Agent or such Lender
Party to make an entry, or any finding that an entry is incorrect, in the
Register or such account or accounts shall not limit or otherwise affect the
obligations of EnergySolutions under this Agreement.

 

Section 2.10                                Manner
of Payment.

 

(a)           Each
payment (including any prepayment) by EnergySolutions on account of the principal
of or interest on the Loans, commitment fees and any other amount owed to the
Lender Parties, the Administrative Agent or any of them under this Agreement
shall be made not later than 2:00 p.m. (New York time) on the date
specified for payment under this Agreement to the Administrative Agent at the
Administrative Agent’s Account, for the account of the Lender Parties, or the
Administrative Agent, as the case may be, in lawful money of the United States
of America in immediately available funds without set-off or counterclaim. Any
payment received by the Administrative Agent after 2:00 p.m. (New York
time) shall be deemed received on the next Business Day. Receipt by the
Administrative Agent of any payment hereunder at or prior to 2:00 p.m.
(New York time) on any Business Day shall be deemed to constitute receipt on
such Business Day. In the case of a payment for the account of a Lender Party,
the Administrative Agent will promptly thereafter (and, if such amount is
received before 2:00 p.m. (New York time), on the same day) distribute the
amount so received in like funds to such Lender Party. If the Administrative
Agent shall not have received any payment from EnergySolutions as and when due,
the Administrative Agent will promptly notify the Lender Parties accordingly. Only
upon its acceptance of an Assignment and Acceptance and recording of the
information contained therein in the Register pursuant to Section 11.5(c),
from and after the effective date of such Assignment and Acceptance, the Administrative
Agent shall make all payments hereunder and under the Notes in respect of the
interest assigned thereby to the Lender Party assignee thereunder, and the parties
to such Assignment and Acceptance shall

 

52

 

make all
appropriate adjustments in such payments for periods prior to such effective
date directly between themselves.

 

(b)           EnergySolutions
agrees to pay principal, interest, fees and all other Obligations due hereunder,
under the Fee Letters, under any Notes or under the other Loan Documents without
set-off or counterclaim or any deduction whatsoever (other than any deductions
or withholdings required by law on account of Taxes).

 

(c)           Prior
to the acceleration of the Loans under Section 8.2
hereof, if some but less than all amounts due from EnergySolutions are received
by the Administrative Agent with respect to the Obligations, the Administrative
Agent shall distribute such amounts in the following order of priority:

 

(i)      first, to the payment
of all of the fees, indemnification payments, costs and expenses that are due
and payable to the Administrative Agent (solely in its capacity as the Administrative
Agent) under or in respect of this Agreement and the other Loan Documents on
such date, ratably based upon the respective aggregate amounts of all such
fees, indemnification payments, costs and expenses owing to the Administrative
Agent on such date;

 

(ii)     second, to the payment
of all of the fees, indemnification payments, costs and expenses that are due
and payable to each Issuing Bank (solely in its capacity as such) under or in
respect of this Agreement and the other Loan Documents on such date, ratably
based upon the respective aggregate amounts of all such fees, indemnification
payments, costs and expenses owing to the such Issuing Bank on such date;

 

(iii)    third, to the payment
of all of the indemnification payments, costs and expenses that are due and
payable to the Lenders under or in respect of this Agreement and the other Loan
Documents on such date, ratably based upon the respective aggregate amounts of
all such indemnification payments, costs and expenses owing to the Lenders on
such date;

 

(iv)    fourth, to the payment
of all of fees and the accrued and unpaid interest and any premiums on the
Obligations of EnergySolutions under or in respect of the Loan Documents that
is due and payable to the Administrative Agent and the Lender Parties, ratably
based upon the respective aggregate amounts of all such interest owing to the
Administrative Agent and the Lender Parties on such date;

 

(v)     fifth, ratably to the
payment of the principal amount of all of the outstanding Loans that is due and
payable to the Administrative Agent and the Lender Parties on such date,
ratably based upon the respective aggregate amounts of all such principal owing
to the Administrative Agent and the Lender Parties on such date and amounts
payable under Secured Hedge Agreements with Lenders and/or their Affiliates (or
Persons that were Lenders or Affiliates of Lenders at the time any such Secured
Hedge Agreement was entered into);

 

(vi)    sixth, to the payment
of all other Secured Obligations of the Loan Parties owing under or in respect
of the Loan Documents or Secured Hedge Agreements that are due and payable to
the Administrative Agent and the other Secured Parties on such date, ratably
based upon the respective aggregate amounts of all such Secured Obligations
owing to the Administrative Agent and the other Secured Parties on such date;
and

 

(vii)   seventh, the balance, if
any, to the person lawfully entitled thereto (including the applicable Loan
Party or its successors or assigns) or as a court of competent jurisdiction may
direct.

 

53

 

(d)           If
the Administrative Agent receives funds for application to the Obligations of
the Loan Parties under or in respect of the Loan Documents under circumstances
for which the Loan Documents do not specify the Loans to which, or the manner
in which, such funds are to be applied, the Administrative Agent may, but shall
not be obligated to, in the case of the Term Loans, for application to such
principal repayment installments thereof, as the Administrative Agent shall
direct, and in other cases, elect to, distribute such funds to each of the
Lender Parties in accordance with such Lender Party’s pro rata share of the sum
of (i) the aggregate principal amount of the Loans outstanding at such
time, (ii) the aggregate Available Amount of all Revolving Letters of
Credit outstanding at such time and (iii) the aggregate amount of the Term
L/C Facility Unreimbursed Amount in respect of Term L/C Facility Letters of
Credit, in repayment or prepayment of such of the outstanding Loans or other
Obligations then owing to such Lender Party.

 

(e)           Subject
to any contrary provisions in the definition of “Interest Period,” if any
payment under this Agreement or any of the other Loan Documents is specified to
be made on a day which is not a Business Day, it shall be made on the next
Business Day, and such extension of time shall in such case be included in
computing interest and fees, if any, in connection with such payment; provided,
however, that, if such extension would cause payment of interest on or
principal of Eurodollar Option Loans to be made in the next following calendar
month, such payment shall be made on the next preceding Business Day.

 

(f)            Unless
the Administrative Agent shall have received notice from EnergySolutions prior
to the date on which any payment is due to any Lender Party hereunder that EnergySolutions
will not make such payment in full, the Administrative Agent may assume that
EnergySolutions has made such payment in full to the Administrative Agent on
such date and the Administrative Agent may, in reliance upon such assumption,
cause to be distributed to each such Lender Party on such due date an amount
equal to the amount then due such Lender Party. If and to the extent
EnergySolutions shall not have so made such payment in full to the
Administrative Agent, each such Lender Party shall repay to the Administrative
Agent forthwith on demand such amount distributed to such Lender Party together
with interest thereon, for each day from the date such amount is distributed to
such Lender Party until the date such Lender Party repays such amount to the
Administrative Agent, at the Federal Funds Rate.

 

Section 2.11                                Reimbursement.

 

(a)           Whenever
any Lender shall sustain or incur any losses or out-of-pocket expenses in connection
with (i) failure by EnergySolutions to borrow any Eurodollar Option Loan
after having given notice of its intention to borrow in accordance with Section 2.2 hereof (whether by reason of EnergySolutions’
election not to proceed or the non-fulfillment of any of the conditions set
forth in Article 3), or (ii) payment
of any Eurodollar Option Loan in whole or in part pursuant to Section 2.2(a)(ii), 2.6,
2.8  10.2
or 11.24, acceleration of the maturity of
the Loans pursuant to Section 8.2
or for any other reason, EnergySolutions agrees to pay to such Lender, upon
demand, an amount sufficient to compensate such Lender for all such losses and
reasonable out-of-pocket expenses. Such Lender’s good faith determination of
the amount of such losses or out-of-pocket expenses, as set forth in writing
pursuant to Section 2.11(b) hereof,
and accompanied by calculations in reasonable detail demonstrating the basis
for its demand, shall be presumptively correct, absent manifest error.

 

(b)           Losses
subject to reimbursement hereunder shall be (i) any loss incurred by any
Lender in connection with the re-employment of funds prepaid, repaid, not
borrowed, or paid, as the case may be, and the amount of such loss shall be the
excess, if any, of (1) the interest or other cost to such Lender of the
deposit or other source of funding used to make any such Eurodollar Option Loan
(but specifically excluding any Applicable Margin) for the remainder of its
Interest Period, over (2) the interest earned (or to be earned) by such
Lender upon the re-lending or other redeployment of the amount of such
Eurodollar

 

54

 

Option Loan
for the remainder of its putative Interest Period or (ii) any other
expenses incurred by any Lender or any participant of such Lender permitted hereunder
in connection with the re-employment of funds prepaid, repaid, not borrowed, or
paid, as the case may be.

 

For the avoidance of doubt, nothing in this Section 2.11
shall be construed to apply to Taxes that are neither Covered Taxes nor Other
Taxes.

 

Section 2.12                                Pro
Rata Treatment.

 

(a)           Each
Loan from the Lenders shall be made pro rata (i) on the basis of the
respective Revolving Commitments of the Revolving Lenders as set forth on Schedule
4-A with respect to Loans made under the Revolving Commitment, (ii) on
the basis of the respective Term Commitments of the Term Lenders as set forth
on Schedule 4-B hereof with respect to Term Loans, (iii) on the
basis of the respective Term L/C Facility Commitments of the Term L/C Facility
Lenders as set forth on Schedule 4-C hereof with respect to Term Loans
and (iv) on the basis of the respective Zion Commitments of the Zion
Lenders as set forth on Schedule 4-D hereof with respect to Zion L/C
Loans.

 

(b)           Payments.
Except as specifically provided in Section 2.2(e)(iv) or
Article 10 hereof or elsewhere in
this Agreement, each payment and prepayment of principal of the Loans or refunding
of the Lender’s Term L/C Facility Collateral Account, and each payment of
interest on the Loans, shall be made to the Lenders pro rata on the basis of
their respective unpaid principal amounts outstanding immediately prior to such
payment or prepayment. If any Lender shall obtain any payment (whether involuntary,
through the exercise of any right of set-off, or otherwise) on account of any
Loans made by it in excess of its ratable share of such Loans, such Lender
shall forthwith purchase from the other Lenders such interests (whether by
purchasing a participation or by assignment) in the applicable Loans made by
them 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, such purchase from each Lender shall be rescinded and each
such Lender shall repay to the purchasing Lender the purchase price to the
extent of such recovery; provided  further, however, that,
so long as the Obligations under the Loan Documents shall not have been
accelerated, any excess payment received by any Lender in respect of any Type
of Loans shall be shared on a pro rata basis only with other Lenders to which
Loans of such Type are owing. EnergySolutions agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section 2.12(b) may, to the fullest extent
permitted by law, exercise all its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Lender were the
direct creditor of EnergySolutions in the amount of such participation.

 

Section 2.13                                Capital
Adequacy.

 

If, after the Third Amended and Restated Credit Agreement Effective
Date, the adoption or effectiveness of any Applicable Law regarding the capital
adequacy of banks or bank holding companies, or any change or effectiveness in
Applicable Law (whether adopted before or after the Third Amended and Restated
Credit Agreement Effective Date) or any change in the interpretation or
administration or effectiveness thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by such Lender Party with any directive issued or
adopted after the Third Amended and Restated Credit Agreement Effective Date
regarding capital adequacy (whether or not having the force of law) of any such
governmental authority, central bank or comparable agency, has or would have
the effect of reducing the rate of return on any Lender Party’s capital, as a
consequence of its obligations hereunder with respect to the Loans, such Lender
Party’s Revolving

 

55

 

Commitment or Zion Commitment or its obligations to issue or
participate in any Revolving Letter of Credit or Zion Letter of Credit
hereunder, to a level below that which it could have achieved but for such
adoption, change or compliance (taking into consideration such Lender Party’s
policies with respect to capital adequacy immediately before such adoption,
change or compliance and assuming that such Lender Party’s capital was fully
utilized prior to such adoption, change or compliance) by an amount reasonably
deemed by such Lender Party to be material, then such Lender Party shall
promptly notify EnergySolutions of such adoption, compliance or change. Upon
demand by such Lender Party, EnergySolutions shall promptly pay to such Lender
Party such additional amounts as shall be sufficient to compensate such Lender
Party for such reduced return, together with interest on such amount from the
fourth (4th) day after the date of demand until payment in full thereof at the
Default Rate. A certificate of such Lender Party setting forth the amount to be
paid to such Lender Party by EnergySolutions as a result of any event referred
to in this paragraph and supporting calculations in reasonable detail shall be
conclusive, absent manifest error. For the avoidance of doubt, this Section 2.13 shall not apply to Taxes.

 

Section 2.14                                Taxes.

 

(a)           Subject
to the exclusions and limitations of this Section 2.14
and subject to the Lenders’ compliance with Section 2.14(f),
any and all payments by any Loan Party hereunder or under the other Loan Documents
shall be made free and clear of and without deduction or withholding for any
and all present or future taxes, levies, imposts, deductions, charges or
withholdings (“Taxes”) imposed or assessed on or with respect to
payments made under this Agreement or the other Loan Documents by the United
States of America or any political subdivisions thereof or therein or any other
jurisdiction (including non-U.S. jurisdictions), and all liabilities with
respect hereto or thereto (but excluding any tax imposed on or measured by the
net income or profits of a Lender or franchise taxes imposed in lieu of net
income taxes on overall gross receipts, or any other similar taxes imposed, in
each case, as a result of such Lender being organized in, having its principal
office or applicable lending office in, engaging in a trade or business in, or
having a present or former connection with the jurisdiction imposing such Tax
(other than any such trade or business, or connection arising or deemed to
arise solely or primarily from any transactions contemplated by this Agreement)
(all such non-excluded taxes, levies, imposts, duties, fees, assessments or
other charges being referred to collectively as “Covered Taxes”).

 

If any Loan Party shall be required by law to withhold or deduct any
Covered Taxes from or in respect of any sum payable hereunder or under any
other Loan Document to any Lender, (i) the sum payable shall be increased
as may be necessary so that after making all required deductions or withholdings
on account of Covered Taxes (including deductions applicable to additional sums
payable under this Section 2.14(a))
such Lender receives an amount equal to the sum it would have received had no
such deductions or withholdings of Covered Taxes been made, (ii) the
applicable Loan Party shall make such deductions or withholdings, and (iii) the
applicable Loan Party shall pay the full amount of Covered Taxes deducted to
the relevant taxation authority or other authority in accordance with
Applicable Law.

 

(b)           EnergySolutions
agrees to pay any present or future recordation, transfer, mortgage, stamp or
documentary taxes or any other excise or property taxes, charges or similar
levies (including any interest and penalties related thereto) imposed by the
United States of America or any political subdivision thereof or any other
jurisdiction (including non-U.S. jurisdictions) that arise from the execution,
delivery, registration of, performance under, or enforcement of, this Agreement
or any other Loan Document (hereinafter referred to as “Other Taxes”).

 

56

 

(c)           Without
duplication of its obligation to pay increased amounts on account of Covered
Taxes and Other Taxes pursuant to Sections 2.14(a) and
(b), respectively, EnergySolutions
shall indemnify each Lender for the full amount of Covered Taxes and Other
Taxes (including, without limitation, any Covered Taxes or Other Taxes imposed
by any jurisdiction on amounts payable under this Section 2.14)
paid by such Lender and any penalties, interest and expenses arising therefrom
or with respect thereto, whether or not such Covered Taxes or Other Taxes were
correctly or legally asserted. Payment by EnergySolutions pursuant to this
indemnification shall be made within thirty (30) days from the date such Lender
(as the case may be) makes written demand therefor (submitted through the
Administrative Agent). A Lender’s failure to provide notice to EnergySolutions
shall not relieve EnergySolutions of any of its obligations under this Section 2.14. Notwithstanding the foregoing, where
notice is not given within one hundred twenty (120) days after the Lender has
actual notice of the assertion of taxes and EnergySolutions does not otherwise
have notice of such assertion, no indemnification shall be required for penalties,
additions to tax, expenses, and interest accruing on such Covered Taxes or
Other Taxes from the date one hundred twenty (120) days after the Lender has
actual notice of the assertion of such taxes until the date such notice was
actually received by EnergySolutions.

 

(d)           Within
thirty (30) days after the date of any payment of Covered Taxes or Other Taxes
by the any Loan Party, such Loan Party shall furnish to the Administrative
Agent, at its address referred to in Section 11.1
hereof, the original or a certified copy of a receipt evidencing payment
thereof. The applicable Loan Party shall compensate each Lender to the extent
that such Lender is required to pay any Covered Taxes or Other Taxes (or
applicable penalties, interest and expenses) as a result of any failure by such
Loan Party to so furnish such copy of such receipt.

 

(e)           The
agreements and obligations of the Loan Parties contained in this Section 2.14 shall survive the indefeasible payment in
full of the Obligations.

 

(f)            Notwithstanding
any provision to the contrary in this Agreement, to the extent that such Person
is at such time legally entitled to do so, on the date a Person becomes an
Agent or Lender hereunder and at such other times as reasonably requested by
EnergySolutions or the Administrative Agent in writing, such Person must
provide to EnergySolutions and the Administrative Agent two properly completed
and duly executed originals of each of the following, as applicable:  (i) Form W-8ECI (in the case of a
non-U.S. Person claiming exemption from withholding because the income is
effectively connected with a U.S. trade or business), (ii) Form W-8BEN
(in the case of a non-U.S. Person claiming exemption from, or reduction of,
withholding tax under an income tax treaty or under the portfolio interest exemption),
(iii) with respect to any interest in this Agreement in which a
participation has been sold, a Form W-8IMY along with accompanying Form W-8BEN
(claiming exemption from withholding under the portfolio interest exemption), (iv) any
other applicable form, certificate or document necessary to establish such
non-U.S. Person’s entitlement to exemption from United States federal
withholding tax or reduced rate with respect to all payments to be made to such
non-U.S. Person under this Agreement, or (v) Form W-9 (claiming exemption
from backup withholding tax), or any successor forms. Each Agent and Lender
agrees that from time to time after the Agreement Date, when a lapse in time or
change in circumstances renders the previous certification obsolete or
inaccurate in any material respect, such Agent or Lender will, to the extent
that such Agent or Lender is at such time legally entitled to do so, deliver to
EnergySolutions and the Administrative Agent two new accurate and complete
original signed copies of the applicable certification form. Notwithstanding
anything to the contrary in this Section 2.14,
a Lender shall not be entitled to payment on account of or indemnification for
Covered Taxes that are U.S. federal withholding Taxes that are imposed pursuant
to a law in effect at the time such Lender becomes a party to this Agreement,
except, in the case of an assignee to the extent that such Lender’s assignor
(if any) was entitled, at the time of assignment, to receive additional amounts
from the Loan Parties with respect to such Tax pursuant to Section 2.14(a) and
a Lender shall not be entitled to a payment on account of or 

 

57

 

indemnification
for such Covered Taxes to the extent such Taxes result from the failure of such
Lender to comply with the documentation requirements of this Section 2.14(f).

 

(g)           If
the Administrative Agent or any Lender determines, in its good faith sole
discretion, that it has received a refund of any Covered Taxes or Other Taxes
as to which it has been indemnified by a Loan Party or with respect to which
the Loan Party has paid additional amounts pursuant to this Section 2.14, it shall pay over such refund to such
Loan Party (but only to the extent of indemnity payments made, or additional
amounts paid, by such Loan Party under this Section 2.14
with respect to the Covered Taxes or Other Taxes giving rise to such refund),
net of all out-of-pocket expenses of such Agent or such Lender and without interest
(other than any interest paid by the relevant governmental authority with respect
to such refund); provided that the Loan Party, upon the request of such
Agent or such Lender, agrees to repay the amount paid over to such Loan Party
to such Agent or such Lender in the event such Agent or such Lender is required
to repay such refund to such governmental authority. This paragraph shall not
be construed to require any Agent or any Lender to make available its tax
returns (or any other information relating to its Taxes which it deems
confidential) to the Loan Party or any other Person. Notwithstanding anything
to the contrary, in no event will any Lender be required to pay any amount to a
Loan Party the payment of which would place such Lender in a less favorable net
after-tax position than such Lender would have been in if the additional
amounts giving rise to such refund of any Covered Taxes or Other Taxes had
never been paid.

 

(h)           Each
Lender agrees that, upon the occurrence of any event giving rise to the operation
of Section 2.14 (a), Section 2.14(c) or Section 10.3
with respect to such Lender, it will, if requested by EnergySolutions, use
reasonable efforts (subject to overall policy considerations of such Lender) to
designate another lending office for any Loans affected by such event with the
object of avoiding the consequences of such event; provided that such
designation is made on terms that, in the good faith sole judgment of such
Lender, cause such Lender and its lending office(s) to suffer no economic,
legal or regulatory disadvantage, and provided  further that
nothing in this Section 2.14 shall affect or
postpone any of the obligations of the Loan Party or the rights of any Lender
pursuant to Section 2.14(a), Section 2.14(c) or Section 10.3.

 

Section 2.15                                Increase
in Commitments.

 

(a)           Borrower
Request. EnergySolutions may by written notice to the Administrative Agent
elect to request (x) prior to the Revolving Maturity Date, an increase to
the existing Revolving Commitments (the “Incremental Commitments”), (y) after
the Third Amended and Restated Effective Date and prior to the Reclamation L/C
Facility Maturity Date, the establishment of one or more Reclamation L/C
Facility Commitments (“Reclamation L/C Facility Commitments”) and (z) prior
to the Term Loan Maturity Date, the establishment of one or more new Term
Commitments (each, an “Incremental Term Commitment”), in the case of the
Incremental Commitments and the Incremental Term Commitments, by an amount not
in excess of the Incremental Commitment Cap in the aggregate and not less than
$5,000,000 individually (or, if less, the amount of the Incremental Commitment
Cap) or, in the case of a Reclamation L/C Facility Commitment no more than the
Reclamation L/C Facility Commitment Cap. Each such notice shall specify (i) the
date (each, an “Increase Effective Date”) on which EnergySolutions
proposes that the increased or new Commitments shall be effective, which shall
be a date not less than 10 Business Days after the date on which such notice is
delivered to the Administrative Agent and (ii) the identity of the
financial institution to whom EnergySolutions proposes any portion of such
increased or new Commitments be allocated and the amounts of such allocations; provided
that any existing Lender approached to provide all or a portion of the
increased or new Commitments may elect or decline, in its sole discretion, to
provide such increased or new Commitment.

 

58

 

(b)           Conditions.
The increased or new Commitments shall become effective, as of such Increase
Effective Date; provided that:

 

(i)      each of the conditions set
forth in Section 3.2 shall be satisfied;

 

(ii)     no Default or Event of
Default shall have occurred and be continuing or would result from the borrowings
to be made on the Increase Effective Date and the use of proceeds thereof;

 

(iii)    EnergySolutions shall deliver
or cause to be delivered any legal opinions or other documents reasonably
requested by the Administrative Agent in connection with any such transaction.

 

(c)           Terms
of New Loans and Commitments. The terms and provisions of Loans made pursuant
to the new Commitments shall be as follows:

 

(i)      terms and provisions of
Loans made pursuant to Incremental Term Commitments (“Incremental Term Loans”)
shall be, except as otherwise set forth herein, identical to the existing Term
Loans (it being understood that Incremental Term Loans may be part of an existing
tranche of Term Loans);

 

(ii)     any such Incremental Term
Loans shall not amortize (on a percentage basis) any faster than the existing
Term Loans and shall not mature prior to the Term Loan Maturity Date;

 

(iii)    in the event that the
Applicable Margin for the Incremental Loans (inclusive of upfront fees and OID
payable to such Lenders) is greater than the Applicable Margin for the existing
Term Loans or the existing Revolving Loans, as applicable (inclusive of any
upfront fees and OID paid to the existing Lenders), then the Applicable Margin
for the corresponding class of existing Loans shall be increased to the extent
necessary such that the Applicable Margin for the existing class of Loans is
equal to the Applicable Margin for the Incremental Loans;

 

(iv)    participation in the
Incremental Term Commitments, Reclamation Facility Commitments and Incremental
Commitments shall be offered to banks, financial institutions and other
entities reasonably acceptable to EnergySolutions and the Administrative Agent;
and

 

(v)     the terms and provisions of
Revolving Loans made pursuant to new Commitments shall be identical to the
Revolving Loans.

 

(d)           Adjustment
of Revolving Loans. In the case of Incremental Commitments, each of the
Revolving Lenders having a Revolving Commitment prior to such Increase
Effective Date (the “Pre-Increase Revolving Lenders”) shall assign to
any Revolving Lender which is acquiring an Incremental Commitment on the
Increase Effective Date (the “Post-Increase Revolving Lenders”), and
such Post-Increase Revolving Lenders shall purchase from each Pre-Increase
Revolving Lender, at the principal amount thereof, such interests in the Revolving
Loans outstanding on such Increase Effective Date as shall be necessary in
order that, after giving effect to all such assignments and purchases, such
Revolving Loans will be held by Pre-Increase Revolving Lenders and
Post-Increase Revolving Lenders ratably in accordance with their Revolving
Commitments after giving effect to the Incremental Commitments.

 

(e)           Making
of New Term Loans. On any Increase Effective Date on which new Commitments
for Term Loans are effective, subject to the satisfaction of the foregoing
terms and conditions, each

 

59

 

Lender of such
new Commitment shall make a Term Loan to EnergySolutions in an amount equal to
its new Commitment.

 

(f)            Equal
and Ratable Benefit. The Loans and Commitments established pursuant to this
paragraph shall constitute Loans and Commitments under, and shall be entitled
to all the benefits afforded by, this Agreement and the other Loan Documents,
and shall, without limiting the foregoing, benefit equally and ratably from the
Guarantees and security interests created by the Security Documents. The Loan
Parties shall take any actions reasonably required by the Administrative Agent
to ensure and/or demonstrate that the Lien and security interests granted by
the Security Documents continue to be perfected under the UCC or otherwise
after giving effect to the establishment of any such Incremental Term Loans or
Incremental Commitments.

 

Section 2.16                                Amendment
or Waiver of Term L/C Facility.

 

In addition to the amendment and waiver provisions provided in Section 11.12 hereto, the following amendment and
waiver provisions shall apply to the Term L/C Facility:

 

(a)           Any amendment or waiver or consent relating
to any delay or extension in the terms of repayment or of the expiration date
of any Term L/C Facility Commitment or Term L/C Facility Loan shall be made
only with the written consent by each Term L/C Facility Lender directly
affected thereby;

 

(b)           No amendment, waiver or consent shall,
unless in writing and signed by the Term L/C Facility Issuing Bank, in addition
to the Term L/C Facility Lenders required above, affect the rights or duties of
the Term L/C Facility Issuing Bank under this Agreement or any Term L/C Facility
Letter of Credit Agreement; and

 

(c)           In addition, any waiver, amendment or
modification of this Agreement that by its terms affects the rights or duties
under this Agreement of the Term L/C Facility Lenders (but not the Term
Lenders, the Revolving Lenders or Zion Lenders) may be effected by an agreement
or agreements in writing entered into by EnergySolutions and the requisite
percentage in interest of the affected class of Lenders that would be required
to consent thereto under Section 11.12
if such Lenders were the only Lenders hereunder at the time; provided  further,
that EnergySolutions shall pay to any Non-Consenting Lender any premium that
would be payable in the event of a prepayment on such date.

 

(d)           Notwithstanding the foregoing, the Term L/C
Facility Lenders agree that it is the intent of parties hereto to reflect the
economic consequences on the conversion of the synthetic letter of credit
facilities created pursuant to the Second Amended and Restated Credit Agreement
into the on-balance sheet Term L/C Facility, as contemplated by the terms
hereof. The Administrative Agent and EnergySolutions may (without the consent
of any Term L/C Facility Lenders) amend or supplement terms relating to the
Term L/C Facility to cure any ambiguity, defect or inconsistency or to make a
modification of a minor, consistency or technical nature or to correct a
manifest error.

 

Section 2.17                                [Reserved].

 

Section 2.18                                Termination
and Reduction of Commitments.

 

(a)           Termination
of Commitments. The Term Commitments expired on June 7, 2006. The
Revolving Commitments and the Revolving Letter of Credit Commitments shall
automatically terminate

 

60

 

at 5:00 p.m.,
New York City time on the Revolving Maturity Date. The Term L/C Facility Letter
of Credit Commitments shall automatically terminate at 5:00 p.m., New York
City time, on the Third Amended and Restated Credit Agreement Effective Date. The
Zion L/C Commitment shall automatically terminate at 5:00 p.m., New York
City time, on the Zion L/C Maturity Date.

 

(b)           Borrower
Notice. EnergySolutions shall notify the Administrative Agent in writing of
any election to terminate or reduce the Revolving Commitments under this Section 2.18 at least three Business Days prior to the
effective date of such termination or reduction, specifying such election and
the effective date thereof. Promptly following receipt of any notice, the
Administrative Agent shall advise the Lenders of the contents thereof. Each
notice delivered by EnergySolutions pursuant to this Section shall be
irrevocable and any termination or reduction of the Revolving Commitments shall
be permanent. Each reduction of the Revolving Commitments shall be made ratably
among the Revolving Lenders in accordance with their respective Revolving
Commitments.

 

ARTICLE 2A.

 

Zion L/C Loans
and Zion Letters of Credit

 

Section 2A.1         Manner of Borrowing and Disbursement.

 

(a)           Issuance
of and Drawings and Reimbursement Under Letters of Credit.

 

(i)            Zion
Letter of Credit Issuance. The Zion Letters of Credit shall be issued on the
Third Amended and Restated Credit Agreement Effective Date or, in the case the
assignment of any Zion Commitment pursuant to Section 11.5(c),
on the date of such assignment.

 

(ii)           Participations.
Upon the issuance of a Zion Letter of Credit by the Zion Issuing Banks, the
Zion Issuing Banks shall be deemed, without further action by any party hereto,
to have sold to each Zion Lender, and each such Zion Lender shall be deemed,
without further action by any party hereto, to have purchased from the Zion
Issuing Banks, a participation in such Zion Letter of Credit in an amount for
each Zion Lender equal to the Dollar Equivalent of such Lender’s Pro Rata Share
of the Available Amount of such Zion Letter of Credit, effective upon the issuance
of such Zion Letter of Credit. In consideration and in furtherance of the
foregoing, each Zion Lender hereby absolutely and unconditionally agrees to pay
such Lender’s Pro Rata Share of each Zion L/C Disbursement made by the Zion
Issuing Banks and not reimbursed by EnergySolutions on the date due of such
Zion L/C Disbursement (or which has been so reimbursed but must be returned or
restored by the Zion Issuing Banks because of the occurrence of an event
specified in Section 8.1(f) or (g) or otherwise) by making available to the Administrative
Agent for the account of the Zion Issuing Banks by deposit to the Administrative
Agent’s Account, in same day funds, an amount equal to the Dollar Equivalent of
such Lender’s Pro Rata Share of such Zion L/C Disbursement. Each Zion Lender
acknowledges and agrees that its obligation to acquire participations pursuant
to this Section 2A.1(a) in respect of
Zion Letters of Credit is absolute and unconditional and shall not be affected
by any circumstance whatsoever, including the occurrence and continuance of a
Default or an Event of Default or the termination of the Commitments, and that
each such payment shall be made without any offset, abatement, withholding or
reduction whatsoever. If and to the extent that any Zion Lender shall not have
so made the amount of such Zion L/C Disbursement available to the Administrative
Agent, such Zion Lender agrees to pay to the Administrative Agent forthwith on
demand such amount together with interest thereon, for each day from the date
such Zion L/C Disbursement is due pursuant to Section 2A.3(b) until
the date such amount is paid to the Administrative Agent, at the Federal Funds
Rate for its account or the account of the Zion Issuing Banks, as applicable. If
such Lender shall pay to the Administrative Agent such amount for the account
of the Zion Issuing Banks on any Business

 

61

 

Day, such
amount so paid in respect of principal shall constitute a Zion L/C Loan made by
such Lender on such Business Day for purposes of this Agreement, and the
outstanding principal amount of the Zion L/C Loan made by the Zion Issuing
Banks shall be reduced by such amount on such Business Day.

 

(iii)          Drawing
and Reimbursement. The payment by the Zion Issuing Banks of a draft drawn
under any Zion Letter of Credit shall constitute for all purposes of this
Agreement the making by the Zion Issuing Banks of a Zion L/C  Loan, which shall be a Base Rate Zion L/C
Loan, in the Dollar Equivalent of the amount of such draft.

 

(iv)          Letter
of Credit Reports. The Zion Issuing Banks shall furnish (A) to the
Administrative Agent on or about the first Business Day of each week a written
report summarizing issuance and expiration dates of Zion Letters of Credit
issued during the previous week and drawings during such week under all Letters
of Credit, (B) to each Zion Lender on or about the first Business Day of
each month a written report summarizing issuance and expiration dates of Zion
Letters of Credit issued during the preceding month and drawings during such
month under all Letters of Credit and (C) to the Administrative Agent and
each Zion Lender on the first Business Day of each calendar quarter a written
report setting forth the average daily aggregate Available Amount during the
preceding calendar quarter of all Zion Letters of Credit.

 

(v)           Failure
to Make Zion L/C Loans. The failure of any Lender to make the Zion L/C Loan
to be made by it on the date specified in Article 2A
shall not relieve any other Lender of its obligation hereunder to make its Zion
L/C  Loan on such date, but no Lender
shall be responsible for the failure of any other Lender to make the Zion
L/C  Loan to be made by such other Lender
on such date.

 

Section 2A.2         Repayment.

 

(a)           Any
unpaid principal and interest of the Zion L/C Loans and any other outstanding
Obligations under the Zion L/C Commitment shall be due and payable in full on
the Zion L/C Maturity Date.

 

(b)           The
Obligations of EnergySolutions and the Zion Lenders with respect to Zion
Letters of Credit under this Agreement, any Letter of Credit Agreement and any
other agreement or instrument relating to any Zion Letter of Credit shall be
unconditional and irrevocable, and shall be paid strictly in accordance with
the terms of this Agreement, such Letter of Credit Agreement and such other
agreement or instrument under all circumstances, including, without limitation,
the following circumstances:

 

(A)          any
lack of validity or enforceability of the L/C Related Documents;

 

(B)           any
change in the time, manner or place of payment of, or in any other term of, all
or any of the Obligations of EnergySolutions in respect of any L/C Related
Document or any other amendment or waiver of or any consent to departure from
all or any of the L/C Related Documents;

 

(C)           the
existence of any claim, set-off, defense or other right that EnergySolutions
may have at any time against any beneficiary or any transferee of a Letter of
Credit (or any Persons for which any such beneficiary or any such transferee
may be acting), the Issuing Bank or any other Person, whether in connection
with the transactions contemplated by the L/C Related Documents or any
unrelated transaction;

 

62

 

(D)          any
statement or any other document presented under a Letter of Credit proving to
be forged, fraudulent, invalid or insufficient in any respect or any statement
therein being untrue or inaccurate in any respect;

 

(E)           payment
by the Issuing Bank under a Letter of Credit against presentation of a draft,
certificate or other document that does not strictly comply with the terms of
such Letter of Credit;

 

(F)           any
exchange, release or non-perfection of any Collateral or other collateral, or
any release or amendment or waiver of or consent to departure from any Guaranty
or any other guarantee, for all or any of the Obligations of EnergySolutions in
respect of the L/C Related Documents; or

 

(G)           any
other circumstance or happening whatsoever, whether or not similar to any of
the foregoing, including, without limitation, any other circumstance that might
otherwise constitute a defense available to, or a discharge of, EnergySolutions
or a guarantor.

 

Section 2A.3         Fees.

 

(a)           [Reserved].

 

(b)           Letter
of Credit Fees.

 

(i)            EnergySolutions
shall pay to the Administrative Agent for the account of each Zion Lender a
commission on such Zion Lender’s Pro Rata Share of the average daily aggregate
Available Amount of all Zion Letters of Credit outstanding from time to time at
a rate per annum equal to the Applicable Margin for Eurodollar Zion L/C Loans
under the Zion L/C Commitments in effect from time to time, if any, payable in
arrears quarterly on the last Business Day of each calendar quarter, commencing
on September 30, 2008, and on the Zion L/C Maturity Date and thereafter
from time to time on demand, shall be fully earned when due, and shall be
non-refundable when paid.

 

(ii)           EnergySolutions
shall pay to the Zion Issuing Banks, for its own account, a Zion Letter of
Credit fronting fee in respect of each Zion Letter of Credit, payable in
arrears quarterly on the last Business Day of each calendar quarter and on the
Zion L/C Maturity Date, of such Zion Letter of Credit, computed at 0.25% per
annum of the face amount of such Zion Letter of Credit, and shall also pay to
the Zion Issuing Banks customary commissions, issuance fees, fronting fees,
transfer fees and other fees and charges in connection with the issuance, administration,
amendment, payment and negotiation of each Zion Letter of Credit. Letter of
Credit commissions shall be computed on the basis of a year of 360 days for the

Section 2A.4         Pro Rata Treatment.

 

(a)           Loans.
Each Zion L/C Loan from the Lenders shall be made pro rata on the basis of the
respective Zion L/C Commitments of the Zion Lenders as set forth on Schedule
4-D with respect to Loans made under the Zion L/C Commitment.

 

(b)           Payments.
Except as specifically provided in Section 2.2
or Article 10 hereof or elsewhere in
this Agreement, each payment and prepayment of principal of the Zion L/C Loans
and each

 

63

 

payment of interest on the Zion L/C Loans, shall be made to the Zion
Lenders pro rata on the basis of their respective unpaid principal amounts
outstanding immediately prior to such payment or prepayment. If any Zion Lender
shall obtain any payment (whether involuntary, through the exercise of any
right of set-off, or otherwise) on account of any Zion L/C Loans made by it in
excess of its ratable share of such Zion L/C Loans, such Zion Lender shall
forthwith purchase from the other Zion Lenders such interests (whether by
purchasing a participation or by assignment) in the applicable Zion L/C Loans
made by them as shall be necessary to cause such purchasing Zion 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 Zion Lender, such purchase from each Zion Lender shall be
rescinded and each such Zion Lender shall repay to the purchasing Zion Lender
the purchase price to the extent of such recovery; provided further, however, that, so long as the Obligations
under the Loan Documents shall not have been accelerated, any excess payment
received by any Zion Lender in respect of any Type of Loans shall be shared on
a pro rata basis only with other Lenders to which Loans of such Type are owing.
EnergySolutions agrees that any Zion Lender so purchasing a participation from
another Zion Lender pursuant to this Section 2A.4
may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Zion Lender were the direct creditor of EnergySolutions in the amount
of such participation.

 

Section 2A.5         Amendment or Waiver of Zion L/C Facility.

 

In addition to the amendment and waiver provisions provided in Section 11.12 hereto, the following amendment and
waiver provisions shall apply to the Zion L/C Facility:

 

(a)           Any
amendment, waiver or consent relating to any delay or extension in the terms of
repayment or of the expiration date of any Zion Commitment or Zion L/C Loan
shall be made only with the written consent by each Zion Lender directly
affected thereby;

 

(b)           No
amendment, waiver or consent shall, unless in writing and signed by the Zion
L/C Issuing Banks, in addition to the Zion Lenders required above, affect the
rights or duties of the Zion L/C Issuing Banks under this Agreement; and

 

(c)           In
addition, any waiver, amendment or modification of this Agreement that by its
terms affects the rights or duties under this Agreement of the Zion Lenders
(but not the Term Lenders, the Revolving Lenders or Term L/C Facility Lenders)
may be effected by an agreement or agreements in writing entered into by
EnergySolutions and the requisite percentage in interest of the affected class
of Lenders that would be required to consent thereto under Section 11.12
if such Lenders were the only Lenders hereunder at the time; provided  further
that EnergySolutions shall pay to any Non-Consenting Lender any premium that
would be payable in the event of a prepayment on such date.

Representations and Warranties

 

Section 4.1             Representations and Warranties.

 

EnergySolutions
hereby agrees, represents and warrants in favor of the Administrative Agent,
the Arranger, the Zion Arrangers and each Lender that:

 

(a)           Organization;
Ownership; Power; Qualification. 
EnergySolutions is a limited liability company, or, to the extent
permitted by Section 7.4(b), a
corporation, duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization. 
EnergySolutions has the limited liability company power, or corporate
power, as applicable, and 

 

68

 

authority to
own its properties and to carry on its business as now being and hereafter
proposed to be conducted.  Each
Subsidiary and Parent is a corporation, limited liability company or a partnership
(as the case may be) duly organized, validly existing and in good standing
under the laws of the state of its incorporation, organization or formation (as
the case may be), and has the necessary power and authority to own its
properties and to carry on its business as now being and hereafter proposed to
be conducted.  EnergySolutions, Parent
and each of their Subsidiaries are duly qualified, in good standing and
authorized to do business in each jurisdiction (other than their respective
jurisdictions of incorporation, organization or formation) in which the
character of their respective properties or the nature of their respective
businesses makes such qualification or authorization prudent, except where the
failure to be so qualified and in good standing would not reasonably be
expected to result in a Material Adverse Change.

 

(b)           Authorization;
Enforceability.  EnergySolutions has
the power and has taken all necessary action to authorize it to borrow
hereunder, to execute, deliver and perform this Agreement and each of the other
Loan Documents to which it is a party in accordance with their respective
terms, and to consummate the transactions contemplated hereby and thereby.  This Agreement has been duly executed and
delivered by EnergySolutions and is, and each of the other Loan Documents to
which EnergySolutions is party is, a legal, valid and binding obligation of
EnergySolutions enforceable against EnergySolutions in accordance with its
terms, subject, as to enforcement of remedies, to the following
qualifications:  (i) an order of
specific performance and an injunction are discretionary remedies and, in
particular, may not be available where damages are considered an adequate
remedy at law, (ii) enforcement may be limited by bankruptcy, insolvency,
liquidation, reorganization, reconstruction and other similar laws affecting enforcement
of creditors’ rights generally (insofar as any such law relates to the
bankruptcy, insolvency or similar event of EnergySolutions), and (iii) enforcement
may be subject to general principles of equity (regardless of whether such
enforcement is considered in a proceeding in equity or at law) and may be
limited by public policies which may affect the enforcement of certain rights
or remedies provided for in this Agreement or the Security Documents.

 

(c)           Subsidiaries and
Parent; Authorization; Enforceability. 
EnergySolutions’ Subsidiaries, Parent’s Subsidiaries and all Investments
of EnergySolutions and Parent and their direct and indirect ownership thereof
are set forth as of the Third Amended and Restated Credit Agreement Effective
Date on Schedule 1, and except as set forth on Schedule 1
attached hereto, EnergySolutions and Duratek have the unrestricted right to
vote the issued and outstanding shares of their corporate Subsidiaries, and the
right to vote their partnership and membership interests in such partnership
and limited liability company Subsidiaries in accordance with the terms of the
applicable partnership agreement or operating agreement shown thereon; such
shares of such corporate Subsidiaries have been duly authorized and issued and
are fully paid and nonassessable.  Each
of EnergySolutions, Parent and their Subsidiaries has the necessary power and
authority, and has taken all necessary action to authorize it, to execute,
deliver and perform each of the Loan Documents to which it is a party in
accordance with their respective terms and to consummate the transactions
contemplated by this Agreement and by such Loan Documents.  Each of the Loan Documents to which a Loan
Party is party is a legal, valid and binding obligation of such Person,
enforceable against such Person in accordance with its terms, subject, as to
enforcement of remedies, to the following qualifications:  (i) an order of specific performance and
an injunction are discretionary remedies and, in particular, may not be
available where damages are considered an adequate remedy at law, (ii) enforcement
may be limited by bankruptcy, insolvency, liquidation, reorganization,
reconstruction and other similar laws affecting enforcement of creditors’
rights generally (insofar as any such law relates to the bankruptcy, insolvency
or similar event of such Subsidiary), and (iii) enforcement may be subject
to general principles of equity 

 

69

 

(regardless of
whether such enforcement is considered in a proceeding in equity or at law) and
may be limited by public policies which may affect the enforcement of certain
rights or remedies provided for in such Loan Documents.

 

(d)           Consents, Applicable
Law, Conflicts and Liens.  Except as
set forth on Schedule 6 hereto, the execution, delivery and performance,
in accordance with their respective terms, by EnergySolutions of this Agreement
and any Notes, and by EnergySolutions, Parent and their respective Subsidiaries
of each of the other Loan Documents to which they are respectively party, and
the consummation of the transactions contemplated hereby and thereby, do not
and will not (i) require any material consent or approval, governmental or
otherwise, not already obtained, (ii) violate any Applicable Law
respecting EnergySolutions, Parent or their respective Subsidiaries, (iii) conflict
with, result in a breach of or constitute a default under the certificate or
articles of incorporation or by-laws, operating agreement or the partnership

EnergySolutions, of Parent or of any of their respective Subsidiaries, or under
any material indenture, agreement, or other instrument, to which EnergySolutions,
Parent or any of their respective Subsidiaries is a party or by which any of
them or their respective properties may be bound, (iv) conflict with,
result in a breach of, or constitute a default or violation of, the terms and
conditions of any of the Necessary Authorizations, except in the case of any
conflict, breach, default or violation of any of the Environmental Permits not
reasonably expected to result, individually or in the aggregate with all other
exceptions to the representations and warranties in Section 4.1(a)(i) hereof,
in a Material Adverse Change or (v) result in or require the creation or
imposition of any Lien upon or with respect to any property now owned or
hereafter acquired by EnergySolutions, Parent or any of their respective
Subsidiaries except for Permitted Liens.

 

(e)           Business.  On the Third Amended and Restated Credit

each of EnergySolutions and Duratek and Parent, together with its Subsidiaries,
each is engaged in the business of owning, operating and investing in the
Permitted Businesses.

authorized by the grantors thereof and are in full force and effect.  EnergySolutions and the Subsidiaries are in
compliance in all material respects with all of the provisions of the Necessary
Authorizations.  Except as set forth on Schedule 7
attached hereto, EnergySolutions and the Subsidiaries have secured all
Necessary Authorizations and all such Necessary Authorizations are in full
force and effect.  Except as set forth on
Schedule 7 attached hereto, none of the material Necessary Authorization
is the subject of any pending or, to EnergySolutions’ or Duratek’s knowledge,
threatened revocation.

 

(g)           Compliance with Law.  EnergySolutions, Parent and their respective
Subsidiaries are in compliance with all Applicable Law except to the extent the
failure to do so would not reasonably be expected to result in a Material
Adverse Change.

 

(h)           Title to Assets.  Each of EnergySolutions, Parent and each of
their respective Subsidiaries has (i) good, defensible, insurable, legal
and beneficial fee simple title to (in the case of fee interests in real

Subsidiaries, is subject to any Liens, except for Permitted Liens.  Except for financing statements evidencing
Permitted Liens, no financing 

 

70

 

statement
under the Uniform Commercial Code as in effect in any jurisdiction and no other
filing which names Parent, EnergySolutions or their respective Subsidiaries as
debtor or which covers or purports to cover any of the assets of Parent,
EnergySolutions or their respective Subsidiaries is currently effective and on
file in any state or other jurisdiction, and none of Parent, EnergySolutions or
their respective Subsidiaries has signed any such financing statement or filing
or any security agreement authorizing any secured party thereunder to file any
such financing statement or filing.

 

(i)            Litigation.  There is no action, suit, revocation,
proceeding or investigation pending against, or, to EnergySolutions’ knowledge,
threatened against or in any other manner relating adversely to, Parent,
EnergySolutions or their respective Subsidiaries or any of their respective
properties, including without limitation any of the Necessary Authorization, in
any court or before any arbitrator of any kind or before or by any governmental
body, except as described on Schedule 8 attached hereto as of the Third
Amended and Restated Credit Agreement Effective Date or as subsequently
disclosed to the Administrative Agent and the Lenders pursuant to Section 6.5 hereof; and no such action, suit,
proceeding or investigation could reasonably be expected to have an adverse
outcome which (i) calls into question the validity of this Agreement or
any other Loan Document, (ii) challenges the continued possession and use
of any License, by Parent, EnergySolutions or their respective Subsidiaries or
any Person in which EnergySolutions has, directly or indirectly, an Investment
and such challenge could result in a Default pursuant to Section 8.1(k) hereof,
or (iii) except as expressly set forth on Schedule 8 (or as
disclosed pursuant to Section 6.5),
could have a Material Adverse Change.

 

(j)            Taxes.  Except as set forth on Schedule 16, as

by law to be filed have been duly filed and all federal, state and other Taxes,
including, without limitation, withholding taxes, assessments and other
governmental charges or levies required to be paid by Parent, EnergySolutions
or their respective Subsidiaries or imposed upon Parent, EnergySolutions or
their respective Subsidiaries or any of their respective properties, income,

such taxes (i) the payment of which Parent, EnergySolutions or any of
their respective Subsidiaries is diligently contesting in good faith by
appropriate proceedings, (ii) for which adequate reserves in accordance
with GAAP have been provided on the books of Parent, EnergySolutions or their
respective Subsidiaries and (iii) as to which no Lien other than a
Permitted Lien has attached and no foreclosure, distraint, sale or similar
proceedings have been commenced and (y) except to the extent the failure
off such tax returns to have been so filed or such taxes to have been paid
would not reasonably be expected to have a Material Adverse Change.  Each of Parent, EnergySolutions or their
respective Subsidiaries has made adequate provision in accordance with GAAP for
all taxes not yet due and payable, except as could not reasonably be likely to,
individually or in the aggregate, have a Material Adverse Change.  Each of Parent, EnergySolutions or their
respective Subsidiaries is unaware of any proposed or pending tax assessments,
deficiencies or audits that could be reasonably expected to, individually or in
the aggregate, result in a Material Adverse Change.  None of Parent, EnergySolutions or their
respective Subsidiaries has ever been a party to any understanding or
arrangement constituting a “tax shelter” within the meaning of Section 6662(d)(2)(C)(iii) of
the Code or within the meaning of Section 6111(c) or Section 6111(d) of
the Code as in effect immediately prior to the enactment of the American Jobs
Creation Act of 2004, or has ever “participated” in a “reportable transaction”
within the meaning of Treasury Regulation Section 1.6011-4, except as
could not reasonably be likely to, individually or in the aggregate, have a
Material Adverse Change.

 

71

 

(k)           Financial Statements.  EnergySolutions has furnished or caused to be
furnished to the Administrative Agent and the Lenders its (or its
predecessor’s) audited financial statements on a consolidated basis with its
Subsidiaries for the fiscal year ended December 31, 2007, which, together
with other financial statements furnished to the Administrative Agent and the
Lenders subsequent to the Agreement Date, are complete and correct in all
material respects and present fairly in accordance with GAAP the financial
position of EnergySolutions and its Subsidiaries on a consolidated basis on and
as at such dates and the results of operations for the periods then ended.  Except as provided on Schedule 9
attached hereto, none of EnergySolutions or any of its Subsidiaries has any
material liabilities, contingent or otherwise, other than (i) as disclosed
in the financial statements referred to in the preceding sentence, (ii) those
that would not reasonably be expected to have a Material Adverse Change and (iii) as
set forth or referred to in this Agreement.

 

(l)            No Adverse Change.  Since December 31, 2007, there has
occurred no event which has had or which could reasonably be expected to have a
Material Adverse Change.

 

(m)          ERISA.  EnergySolutions and each Subsidiary and each
of their respective Plans are in compliance in all respects with ERISA and the
Code, including Section 4980 B of the Code, except as could not reasonably
be expected to have a Material Adverse Change. 
Neither Parent nor any of its Subsidiaries has incurred any accumulated
funding deficiency within the meaning of Section 412 of the Code with
respect to any Plan.  No ERISA Affiliate
has incurred any accumulated funding deficiency within the meaning of Section 412
of the Code with respect to any ERISA Affiliate Plan, except as could not
reasonably be expected to have a Material Adverse Change.  No Reportable Event, for which the 30-day
notice requirement has not been waived, has occurred and is continuing with
respect to any Plan, except as could not reasonably be expected to result in a
Material Adverse Change.  No Plan or
trust created thereunder, or party in interest (as defined in Section 3(14)
of ERISA), or any fiduciary (as defined in Section 3(21) of ERISA), has
engaged in a “prohibited transaction” (as such term is defined in Section 406
of ERISA or Section 4975 of the Code) which would reasonably be expected
to subject Parent or any of its Subsidiaries to a tax or penalty in any amount
on “prohibited transactions” imposed by Section 502 of ERISA or Section 4975
of the Code or an obligation to indemnify any other person for such tax or

such investigation, litigation or proceeding is brought by any Loan Party, its
members, managers, directors, shareholders or creditors or an Indemnitee or any

Within sixty
(60) days from the Third Amended and Restated Credit Agreement Effective Date,
and at the end of each fiscal quarter thereafter, EnergySolutions shall have
entered into or maintained in effect one or more Hedge Agreements in such
aggregate notional amount as necessary so that, with respect 

 

81

 

to no less
than thirty-three percent (33%) of the then outstanding aggregate principal
balance of the Term Loans and the Duratek Loans, EnergySolutions’ obligations
to make floating rate interest payments thereunder will be hedged with fixed
rate payments to be paid under such Hedge Agreements.  Such Hedge Agreements shall provide interest
rate protection on terms (including, without limitation, consideration of the
creditworthiness of the other party to the proposed Hedge Agreement) reasonably
acceptable to (and with parties reasonably acceptable to) the Administrative
Agent for an average period of the lesser of (a) two (2) years from
the date of such Hedge Agreement or Hedge Agreements and (b) the period
remaining from the date thereof until the Term Loan Maturity Date.  All Secured Obligations of EnergySolutions to
any of the Lenders pursuant to any Secured Hedge Agreement shall rank pari
passu with all other Secured Obligations. 
Any prepayment, acceleration, reduction, increase or any other change in
the terms of the Loans hereunder will not alter the notional amount of any such
Secured Hedge Agreement or otherwise affect EnergySolutions’ obligation to
continue making payments under any such Secured Hedge Agreement, which will
remain in full force and effect notwithstanding any such prepayment,
acceleration, reduction, increase or change, subject to the terms of such
Secured Hedge Agreement.

 

Section 5.13           Covenants Regarding

Agreement, EnergySolutions and Parent each will, and will cause their
respective Subsidiaries, as appropriate, to, (i) in the case of the
formation or Acquisition of a new Subsidiary, provide to the Administrative
Agent an executed Subsidiary Security Agreement for such new Subsidiary (other

Subsidiary Security Agreement is required), in substantially the form of Exhibit J
attached hereto, together with appropriate UCC-1 financing statements, as well
as an executed Subsidiary Guaranty for such new Subsidiary (other than any
Non-U.S. Subsidiary or Special Purpose Subsidiary, for which no such Subsidiary
Guaranty is required), in substantially the form of Exhibit H
attached hereto, which shall constitute both Security Documents and Loan
Documents for purposes of this Agreement, as well as a loan certificate for
such new Subsidiary, substantially in the form of Exhibit M, Exhibit N
or Exhibit O attached hereto, as appropriate, together with
appropriate attachments; (ii) in the case of any Acquisition by
EnergySolutions, Parent or any of their respective Subsidiaries or the
formation of any new Subsidiary, pledge to the Collateral Agent all of the
capital stock, limited partnership interests, general partnership interests, or
other securities or other equity or ownership interests of such Subsidiary or
Person which is acquired or formed, beneficially owned by EnergySolutions,
Parent or any of their respective Subsidiaries, as the case may be, as additional
Collateral for the Secured Obligations to be held by the Collateral Agent in
accordance with the terms of EnergySolutions’ Pledge Agreement, Parent Pledge
Agreement, Subsidiary Pledge Agreement or a new Subsidiary Pledge Agreement (it
being understood that (i) no Non-U.S. Subsidiary or Special Purpose
Subsidiary shall be required to execute any such Subsidiary Pledge Agreement
and (ii) no Loan Party shall be required to pledge any equity or ownership
interest in a newly acquired Subsidiary if (A) such pledge is prohibited
by the terms of such Subsidiary’s organizational documents or (B) such
Subsidiary is a Special Purpose Subsidiary) in substantially the form of Exhibit A
attached hereto, and execute and deliver to the Collateral Agent all such
documentation for such pledge as, in the reasonable opinion of the Collateral
Agent, is appropriate; provided that (A) in the case of any
Acquisition by EnergySolutions or Parent or any of their respective
Subsidiaries or the formation of any new Subsidiary that is a “first tier”
Non-U.S. Subsidiary, not more than 65% of the capital stock, limited
partnership interests, general partnership interests, or other securities or

Agent as additional Collateral for the Secured Obligations to be held by the
Collateral Agent in accordance with the terms of EnergySolutions’ Pledge
Agreement, Parent Pledge Agreement, Subsidiary Pledge Agreement or a new
Subsidiary Pledge Agreement and (B) the requirement that any new
Subsidiary of any of EnergySolutions or Parent or any of their respective
Subsidiaries execute a Subsidiary Guaranty and a Subsidiary Security Agreement
shall not apply to a new non-wholly owned Subsidiary if, but only for so long
as, (x) such Subsidiary has total assets of less than $5,000,000

case, provide all other documentation, including one or more opinions of
counsel reasonably satisfactory to the Collateral Agent, which in the reasonable
opinion of the Collateral Agent is appropriate with respect to such
Acquisition, Real Property Acquisition or the formation of such
Subsidiary.  Investments made by
EnergySolutions, Parent or any of their respective Subsidiaries after the Agreement
Date shall also be treated as additional Collateral and shall be subject to the

items that would be added to the net income of Duratek and its Subsidiaries in
the calculation of the operating cash flow of Duratek and its Subsidiaries

Expenditures of EnergySolutions and the Subsidiaries on a consolidated basis in
any one fiscal year (ending on or after December 31, 2005) are less than
the maximum amount permitted pursuant to this Section 7.7(d),
then EnergySolutions and its Subsidiaries on a consolidated basis may expend an
additional amount on Capital Expenditures in a subsequent fiscal year equal to
the dollar amount of the lesser of the shortfall from such fiscal year and 50%
of the amount permitted for Capital Expenditures in the prior fiscal year;

of Adjusted Net Income, for each consecutive four fiscal quarter period
thereafter, provided that for the 2009 fiscal year and each fiscal year

amount that could reasonably be expected to have a Material Adverse Change if
the Plans were terminated.

Interest shall cease to be perfected, except if such failure results from the
Collateral Agent’s failure to file any UCC-l financing statement or UCC-3
continuation statement in the appropriate jurisdiction or to maintain
possession or control of such portion of the Collateral as a result of a sale
or assignment of such Collateral by the Collateral Agent; or

 

(n)           There shall occur a

necessary) and distributed by the Administrative Agent as follows:  first, to reimburse the reasonable costs and

Lender Parties in same day funds at the Administrative Agent’s office
designated in such demand, for deposit in the L/C Collateral Account, an amount
equal to the aggregate Available Amount of all Zion Letters of Credit and Revolving

at any time the Administrative Agent determines that any funds held in the L/C
Collateral Account are subject to any right or claim of any Person other than
the Agents and the Lender Parties or that the total amount of such funds is
less than the aggregate Available Amount of all Revolving Letters of Credit,
EnergySolutions will, forthwith upon demand by the Administrative Agent, pay to
the Administrative Agent, as additional funds to be deposited and held in the
L/C Collateral Account, an amount equal to the excess of (a) such
aggregate Available Amount over (b) the total amount of funds, if any,
then held in the L/C Collateral Account that the Administrative Agent determines
to be free and clear of any such right and claim.  Upon the drawing of any Zion Letter of Credit
and Revolving Letter of Credit for which funds are on deposit in the L/C Collateral

Lenders or Revolving Issuing Bank or Revolving Lenders, as applicable, to the
extent permitted by Applicable Law.

until the expiration of the 20th day subsequent to the date the certificate
calculating such Financial Condition Covenant is required to be delivered
pursuant to Section 6.3, Parent shall
have the right to issue equity interests to the Equity Sponsors for cash, and,
in each case, to contribute any such cash to the capital of EnergySolutions (collectively,

the exercise
by Parent of such Cure Right such Financial Condition Covenant shall be recalculated
giving effect to the following pro forma adjustments:

 

(i)      Operating Cash Flow shall be
increased, solely for the purpose of measuring the Financial Condition
Covenants and not for any other purpose under this Agreement, by an amount
equal to the Cure Amount; and

 

(ii)     If, after giving effect to
the foregoing recalculations, Parent and EnergySolutions shall then be in
compliance with the requirements of all Financial Condition Covenants, Parent
and EnergySolutions shall be deemed to have satisfied the requirements of the
Financial Condition Covenants as of the relevant date of determination with the
same effect as though there had been no failure to comply therewith at such
date, and the applicable breach or default of the Financial Condition Covenants
which had occurred shall be deemed cured for all purposes of this Agreement.

 

(b)           Limitations on
Exercise of Cure Right, etc. 
Notwithstanding anything herein to the contrary, (a) in no event
shall Parent be entitled to exercise the Cure Right in more than two

amount required to cure the applicable failure to comply with a Financial
Condition Covenant.  To the extent a
fiscal quarter ended for which the Financial Condition Covenants are initially
recalculated as a result of a Cure Right is included in the calculation of a
Financial Condition Covenant in a subsequent fiscal period, the Cure Amount
shall be included in the amount of Operating Cash Flow for such initial fiscal
period.

The Agents

 

Section 9.1             Appointment and Authorization.

 

Each Lender
(in its capacities as a Lender and an Issuing Bank (if applicable)) hereby
consents to the assignment by Calyon of all of its rights and duties as the
Administrative Agent and Collateral Agent to CNAI pursuant to the Successor
Agent Agreement and hereby irrevocably appoints and authorizes, and hereby
agrees that it will require any transferee of any of its interest in its Loans
irrevocably to appoint and authorize, CNAI as the Administrative Agent and the
Collateral Agent, as applicable, to take such actions as agents on its behalf
and to exercise such powers hereunder, under the Security Documents as are
delegated by the terms hereof and thereof, together with such powers as are
reasonably incidental thereto. 
Notwithstanding anything in the Loan Documents to the contrary, neither
Calyon (as administrative and collateral agent under the Original Credit
Agreement), the Administrative Agent, the Collateral Agent nor any of their respective
directors, officers, employees or agents shall be liable for any action taken
or omitted to be taken by it or them hereunder or in connection herewith (or,
with respect to Calyon, the Original Credit Agreement), except for its or their
own gross negligence or willful misconduct.

 

Section 9.2             Interest Holders.

 

The
Administrative Agent may treat each Lender Party, or the Person designated in
the last notice filed with the Administrative Agent, whether under Section 11.1, Section 11.5

Party in its Loans or Commitments until written notice of transfer, signed by
such Lender Party (or the Person designated in the last notice filed with the
Administrative Agent)

and by the
Person designated in such written notice of transfer, in form and substance
satisfactory to the Administrative Agent, shall have been filed with the Administrative
Agent.

With respect
to its Commitments and the Loans made by it and the Notes issued to it, if any,

information obtained or received by it or any of its Affiliates relating to any
Loan Party or any of its Subsidiaries to the extent such information was

the use of such term or for any other reason, have any duties or
responsibilities except those expressly set forth herein or in the other Loan
Documents, or any fiduciary relationship with any Lender, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities
shall be read into this Agreement or otherwise exist against the Administrative
Agent or the Collateral Agent.  Each of
the Administrative Agent and the Collateral Agent shall be entitled to assume

or has been notified by EnergySolutions, of such fact or has been notified by a
Lender Party in writing that such Lender Party considers that a Default has
occurred and is continuing, and such Lender Party shall specify in detail the
nature thereof in writing.  Each of the

Documents, is hereby authorized to act on behalf of the Secured Parties, in its
own capacity and through other agents and sub-agents appointed by it with due
care, under the Security Documents.  In

for the ratable benefit of the Secured Parties, and such role as Collateral
Agent shall be disclosed on all appropriate accounts, certificates, filings,
mortgages and other Collateral documentation.

 

(b)                                 The
Lender Parties irrevocably authorize the Collateral Agent, at its option and in
its discretion, and the Collateral Agent may, without further written consent
or authorization from Lenders (subject to Section 11.12
hereof), and agrees with and for the benefit of EnergySolutions that it shall
execute any documents or instruments and take any further actions, in each case
at the sole cost and expense of EnergySolutions, necessary:

 

(i)                  to release any
Lien on any property granted to or held by the Collateral Agent under any Loan
Document (A) upon termination of the Commitments and payment in full of
all Secured Obligations (other than contingent indemnification obligations) and
the expiration or termination of all Letters of Credit, (B) that is sold
or transferred or to be sold or transferred as part of or in connection with

writing by the Majority Lenders; or

 

(ii)               to release any
Guarantor (other than Parent) from its obligations under the Guaranty if such
Person ceases to be a Subsidiary as a result of a transaction permitted
hereunder.

 

Upon request
by the Administrative Agent at any time, the Majority Lenders will confirm in
writing the Administrative Agent’s or the Collateral Agent’s authority to

or to release any Guarantor from its obligations under the Guaranty pursuant to
this Section 9.7.

 

Section 9.8                                      Action
by the Administrative Agent and the Collateral Agent.

 

(a)                                  Each
of the Administrative Agent and the Collateral Agent shall be entitled to use
its discretion with respect to exercising or refraining from exercising any
rights which may be vested in it by, and with respect to taking or refraining
from taking any action or actions which it may be able to take under or in
respect of, this Agreement, unless the Administrative Agent or the Collateral
Agent, as applicable, shall have been instructed by the Majority Lenders to
exercise or refrain from exercising such rights or to take or refrain from
taking such action.  Neither the
Administrative Agent nor the Collateral Agent shall incur any liability under
or in respect of this Agreement with respect to anything which it may do or
refrain from doing in the reasonable exercise of its judgment or which may seem
to it to be necessary or desirable in the circumstances for the protection of
the interests of the Lender Parties, except for its gross negligence or willful
misconduct as determined by a final, non-appealable order of a court having
jurisdiction over the subject matter.

(b)                                 In
any event, neither the Collateral Agent nor the Administrative Agent shall be
liable to the Lenders or to any Lender in acting or refraining from acting

instructions of the Majority Lenders or of all the Lenders, where expressly
required by this Agreement, and any action taken or failure to act pursuant to

Agreement as the Majority Lenders or of all the Lenders, where expressly

assert rights under this Agreement in respect of any Default within ten (10) days
after their receipt of the notice of any Default from the Administrative Agent
or any Lender Party, or shall request inconsistent action with respect to such
Default, the Administrative Agent may, but shall not be required to, take such
action and assert such rights as it deems in its discretion to be advisable for
the protection of the Lender Parties.

(c)                                  For
purposes of this Section 9.11, the Lender
Parties’ respective ratable shares of any amount shall be determined, with
respect to any time deemed appropriate by such Agent, according to the sum of (i) the
aggregate principal amount of the Loans outstanding at such time and owing to
the respective Lender Parties, (ii) their respective Pro Rata Shares of
the aggregate Available Amount of all Letters of Credit outstanding at such
time, (iii) the aggregate unused portions of their respective Revolving
Commitments at such time and (iv) the aggregate unused portions of their
respective Zion L/C Commitments at such time; provided that the aggregate
principal amount of Letter of Credit Loans owing to the Revolving Issuing Bank
shall be deemed “owed to” the Revolving Lenders ratably in accordance with
their respective Revolving Commitments and the aggregate principal amount of
Letter of Credit Loans owing to the Zion L/C Issuing Banks shall be deemed “owed
to” the Zion Lenders ratably in accordance with their respective Zion
Commitments.  The failure of any Lender
Party to reimburse any Agent, the Revolving Issuing Bank or the Zion L/C
Issuing Banks, as the case may be, promptly upon demand for its ratable share
of any amount required to be paid by the Lender Parties to such Agent, the
Revolving Issuing Bank or the Zion L/C Issuing Banks, as the case may be, as
provided herein shall not relieve any other Lender Party of its obligation
hereunder to reimburse such Agent, the Revolving Issuing Bank or the Zion L/C
Issuing Banks, as the case may be, for its ratable share of such amount, but no
Lender Party shall be responsible for the failure of any other Lender Party to
reimburse such Agent, the Revolving Issuing Bank or the Zion L/C Issuing Banks,
as the case may be, for such other Lender Party’s ratable share of such
amount.  Without prejudice to the
survival of any other agreement of any Lender Party hereunder, the agreement
and obligations of each Lender Party contained in this Section 9.11
shall survive the payment in full of principal, interest and all other amounts
payable hereunder and under the other Loan Documents.

 

Section 9.12                                Credit
Decision.

 

Each Lender Party represents and warrants to each other Lender Party,
to each Agent and to the Administrative Agent that:

 

(a)                                  in
making its decision to enter into this Agreement and to make its Loans it has
independently taken whatever steps it considers necessary to evaluate the
financial condition and affairs of EnergySolutions and the Subsidiaries and
that it has made an independent credit judgment, and that it has not relied
upon the Administrative Agent, any Agent or any other Lender Party, or
information provided by the Administrative Agent (other than information
provided to

 

109

 

the
Administrative Agent by EnergySolutions and forwarded by the Administrative
Agent to the Lender Parties); and

 

(b)                                 so
long as any portion of the Obligations remains outstanding, it will continue to
make its own independent evaluation of the financial condition and affairs of
EnergySolutions and the Subsidiaries.

 

Section 9.13                                Successor
Agents.

 

(a)                                  Resignation
of Administrative Agent.  The
Administrative Agent may resign at any time by giving written notice five days
prior to the effective date of such resignation to the Lender Parties and
EnergySolutions.  Upon any such
resignation, the Majority Lenders shall have the right, in consultation with
EnergySolutions, to appoint a successor Administrative Agent; provided,
that, at the time of the resignation of the Administrative Agent, no successor
Administrative Agent has been appointed by the Majority Lenders, the retiring
Administrative Agent may, on behalf of the Lender Parties, appoint a successor
Administrative Agent, which shall be any Lender Party or a commercial bank organized
under the laws of the United States of America or any political subdivision
thereof which has combined capital and reserves in excess of $250,000,000.  Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor Administrative Agent, such successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges, duties and obligations of the retiring
Administrative Agent and the retiring Administrative Agent shall be discharged
from its duties and obligations under the Loan Documents.  After any retiring Administrative Agent’s
resignation hereunder as Administrative Agent (including, for the avoidance of
doubt, Calyon’s resignation as administrative agent pursuant to the Successor
Agent Agreement), the provisions of this Article shall continue in effect
for its benefit in respect of any actions taken or omitted to be taken by it
while it was acting as the Administrative Agent (and with respect to Calyon, including
any action taken or omitted to be taken subsequent to its resignation in
connection with (x) the payoff of the Original Term Loans or (y) other
obligations under the Original Credit Agreement).

 

(b)                                 Resignation
of Collateral Agent.  The Collateral
Agent may resign at any time by giving written notice of such resignation to
the Lender Parties and EnergySolutions. 
Upon any such resignation, the Majority Lenders shall have the right, in
consultation with EnergySolutions, to appoint a successor Collateral Agent; provided
that if, at the time of the resignation of the Administrative Agent, no
successor Collateral Agent has been appointed by the Majority Lenders, the
retiring Collateral Agent may, on behalf of the Lender Parties, appoint a
successor Collateral Agent and, after its resignation and prior to the appointment
of any successor Collateral Agent, the retiring Collateral Agent will act as a
nominee for perfection with respect to the applicable Collateral.  Upon the acceptance of any appointment as
Collateral Agent hereunder by a successor Collateral Agent, such successor
Collateral Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges, duties and obligations of the retiring Collateral
Agent and the retiring Collateral Agent shall be discharged from its duties and
obligations under the Loan Documents. 
After any retiring Collateral Agent’s resignation hereunder as Collateral
Agent (including, for the avoidance of doubt, Calyon’s resignation as
collateral agent pursuant to the Successor Agent Agreement), the provisions of
this Article shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as the
Collateral Agent (and with respect to Calyon, including any action taken or
omitted to be taken subsequent to its resignation in connection with the payoff
of the Original Term Loans).

 

(c)                                  General.  If no successor agent shall have been
appointed and shall have accepted such appointment prior to the resignation of
the Administrative Agent or Collateral Agent, then the retiring Administrative
Agent or Collateral Agent, as applicable, shall thereupon be discharged from
its duties and

 

110

 

obligations
under the Loan Documents and the Majority Lenders shall thereafter perform all
duties of the retiring Administrative Agent or Collateral Agent, as applicable,
under the Loan Documents until such time, if any, as the Majority Lenders
appoint a successor Administrative Agent or Collateral Agent, as applicable, as
provided above.  After any retiring agent’s
resignation hereunder as Administrative Agent or Collateral Agent shall have
become effective (including, for the avoidance of doubt, Calyon’s resignation
as administrative agent and collateral agent pursuant to the Successor Agent
Agreement), the provisions of this Article 9
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Administrative Agent or Collateral Agent, as applicable, under
this Agreement (and with respect to Calyon, including any action taken or
omitted to be taken subsequent to its resignation in connection (x) with
the payoff of the Original Term Loans or (y) other obligations under the
Original Credit Agreement).

 

Section 9.14                                Delegation
of Duties.

 

The
Administrative Agent may execute any of its duties under the Loan Documents by
or through agents or attorneys selected by it using reasonable care, and shall
be entitled to advice of counsel concerning all matters pertaining to such
duties.

Agents.

 

None of the
Lender Parties or other entities identified on the facing page of, signature
pages of or elsewhere in this Agreement as a “syndication agent,” “documentation
agent,” “sole bookrunner” or “sole lead arranger” shall have any right, power,
obligation, liability, responsibility or duty under this Agreement or any other
Loan Document other than those applicable to all Lender Parties as such.  Without limiting the foregoing, none of the
Lender Parties so identified shall have or be deemed to have any fiduciary
relationship with any other Lender Party. 
Each Lender Party acknowledges that it has not relied, and will not
rely, on any of the Lender Parties or other entities so identified in deciding
to enter into this Agreement or any other Loan Document or in taking or not
taking action hereunder or thereunder.

 

Section 9.16                                Administrative
Agent May File Proofs of Claim.

 

(a)                                  In
case of the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to any Loan Party, the Administrative Agent or its designee
(irrespective of whether the principal of any Loan or Letter of Credit shall
then be due and payable as herein expressed or by declaration or otherwise and
irrespective of whether the Administrative Agent shall have made any demand on
EnergySolutions) shall be entitled and empowered, by intervention in such
proceeding or otherwise:

 

(i)                  to file and
prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Loans, Letter of Credit Agreement and all other
Obligations that are owing and unpaid and to file such other documents as may
be necessary or advisable in order to have the claims of the Lender Parties and
the Administrative Agent (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Lender Parties and the
Administrative Agent and their respective agents and counsel and all other
amounts due the Lender Parties and the Administrative Agent under Sections 2.3, 2.5 and 11.2) allowed in such judicial proceeding; and

 

(ii)               to collect and receive
any monies or other property payable or deliverable on any such claims and to
distribute the same;

 

111

 

and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each
Lender Party to make such payments to the Administrative Agent and, in the
event that the Administrative Agent shall consent to the making of such
payments directly to the Lender Parties, to pay to the Administrative Agent any
amount due for the reasonable compensation, expenses, disbursements and
advances of the Administrative Agent and its agents and counsel, and any other
amounts due the Administrative Agent under Sections 2.5
and 11.2.

 

(b)                                 Nothing
contained herein shall be deemed to authorize the Administrative Agent to authorize
or consent to or accept or adopt on behalf of any Lender Party any plan of
reorganization, arrangement, adjustment or composition affecting the
Obligations or the rights of any Lender Party or to authorize the
Administrative Agent to vote in respect of the claim of any Lender Party in any
such proceeding.

Documents.

 

Notwithstanding
anything herein to the contrary, each Lender also acknowledges that CNAI, Collateral
Agent hereunder, is also acting as Collateral Agent under the Duratek Loan
Agreement, and in such dual capacities has entered into the Security Documents
on behalf of both the Secured Parties hereunder as well as the secured parties
under the Duratek Loan Agreement, each Secured Party hereby waiving any actual
or potential conflict or breach of duty created or existing as the result of
such dual capacities and acknowledging that it has read the terms and
conditions of the Security Documents and has accepted the same without reliance
on any of the Agents.

 

ARTICLE 10.

 

Change in Circumstances Affecting Fixed Rate
Loans

 

Section 10.1                                Eurodollar
Basis Determination Inadequate or Unfair.

 

If, with
respect to any proposed Eurodollar Option Loan for any Interest Period, the
Administrative Agent determines after consultation with the Lenders that
deposits in Dollars (in the applicable amount) are not being offered to each of
the Lenders in the relevant market for such Interest Period, the Administrative
Agent shall forthwith give notice thereof to EnergySolutions and the Lenders,
whereupon until the Administrative Agent notifies EnergySolutions that the
circumstances giving rise to such situation no longer exist, the obligations of
any affected Lender to make or continue Eurodollar Option Loans shall be
suspended.

 

Section 10.2                                Illegality.

 

If after the
Third Amended and Restated Credit Agreement Effective Date the adoption of any
Applicable Law, or any change in any Applicable Law (whether adopted before or
after the Third Amended and Restated Credit Agreement Effective Date), or any
change in interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender with any directive (whether
or not having the force of law) of any such authority, central bank or
comparable agency, shall make it unlawful or impossible, or any such
governmental authority, central bank or comparable agency shall assert that it
is unlawful, for any Lender to make, maintain or fund Eurodollar Option Loans,
such Lender shall so notify

 

112

 

the
Administrative Agent, and the Administrative Agent shall forthwith give notice
thereof to the other Lenders and EnergySolutions.  Before giving any notice to the
Administrative Agent pursuant to this Section 10.2,
such Lender shall designate a different lending office if such designation will
avoid the need for giving such notice and will not, in the sole judgment of
such Lender, be otherwise materially disadvantageous to such Lender.  Upon receipt of such notice, notwithstanding
anything contained in Article 2
hereof, (a) the obligation of the Lenders to make or continue Eurodollar
Option Loans shall be suspended until the Administrative Agent shall notify
EnergySolutions and the Lenders that the circumstances causing such suspension
no longer exist and (b) unless EnergySolutions, within three (3) Business
Days thereafter, converts all Eurodollar Option Loans into Base Rate Option
Loans in accordance with the terms of this Agreement, EnergySolutions shall
repay in full the then outstanding principal amount of each affected Eurodollar
Option Loan of such Lender, together with accrued interest thereon and any reimbursement
required under Section 2.11 hereof, on
either (i) the last day of the then current Interest Period applicable to
such affected Eurodollar Option Loans if such Lender may lawfully continue to
maintain and fund such Eurodollar Option Loans to such day or (ii) immediately
if such Lender may not lawfully continue to fund and maintain such affected
Eurodollar Option Loans to such day. 
Concurrently with repaying each affected Eurodollar Option Loan of such
Lender, notwithstanding anything contained in Article 2
or Article 3 hereof, EnergySolutions
may borrow a Base Rate Option Loan from such Lender, and such Lender shall make
such Base Rate Option Loan, if so requested, in an amount such that the outstanding
principal amount held by such Lender shall equal the outstanding principal
amount immediately prior to such repayment.

 

Section 10.3                                Increased
Costs.

 

(a)                                  If
after the Third Amended and Restated Credit Agreement Effective Date the
adoption or effectiveness of any Applicable Law or any change or effectiveness
in any Applicable Law (whether adopted before or after the Third Amended and
Restated Credit Agreement Effective Date) or any interpretation or change in
interpretation or administration or effectiveness thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof or compliance by any Lender Party with any directive
(whether or not having the force of law) of any such authority, central bank or
comparable agency:

 

(i)                                     shall
subject any Lender Party to any tax, duty or other charge with respect to its
obligation to make or continue Eurodollar Option Loans, or its Eurodollar Option
Loans or Term L/C Facility Loans, or shall change the basis of taxation of
payments to any Lender Party of the principal of or interest on its Eurodollar
Option Loans, Term L/C Facility Loans or in respect of any other amounts due
under this Agreement, in respect of its Eurodollar Option Loans, Term L/C
Facility Loans or its obligation to make or continue Eurodollar Option Loans
(except for changes in the rate or method of calculation of tax on the overall
net income of such Lender Party); or

 

(ii)                                  shall
impose, modify or deem applicable any reserve (including, without limitation,
any imposed by the Board of Governors of the Federal Reserve System, but
excluding any included in an applicable Eurodollar Reserve Percentage), special
deposit, capital adequacy, assessment or other requirement or condition against
assets of, deposits with or for the account of, or commitments or credit
extended by, any Lender Party or shall impose on any Lender Party or the London
interbank borrowing market or the New York certificate of deposit market any
other condition affecting its obligation to make or continue Eurodollar Option
Loans or its Eurodollar Option Loans or Term L/C Facility Loans;

 

113

 

and the result
of any of the foregoing is to increase the cost to such Lender Party of making
or maintaining any such Eurodollar Option Loans or Term L/C Facility Loans, or
of agreeing to issue or of issuing or maintaining or participating in Letters
of Credit or of agreeing to make or of making or maintaining Letter of Credit
Loans, or to reduce the amount of any sum received or receivable by such Lender
Party under this Agreement with respect thereto, then, within five (5) days
after demand by such Lender Party, EnergySolutions agrees to pay to such Lender
Party such additional amount or amounts as will compensate such Lender Party
for such increased costs (other than any increased costs resulting from Taxes
that are Covered Taxes or Other Taxes (which shall be governed exclusively by Section 2.14) or are excluded from the definition of
Covered Taxes under Section 2.14(a)).  Each Lender Party will promptly notify EnergySolutions
and the Administrative Agent of any event of which it has knowledge, occurring
after the Third Amended and Restated Credit Agreement Effective Date, which
will entitle such Lender Party to compensation pursuant to this Section 10.3 and will designate a different lending
office if such designation will avoid the need for, or reduce the amount of,
such compensation and will not, in the sole judgment of such Lender Party, be
otherwise disadvantageous to such Lender Party.

 

(b)                                 Any
Lender Party claiming compensation under this Section 10.3
shall provide EnergySolutions with a written certificate setting forth the
additional amount or amounts to be paid to it hereunder and calculations
therefor in reasonable detail.  Such
certificate shall be presumptively correct, absent manifest error.  In determining such amount, such Lender Party
may use any reasonable averaging and attribution methods.  If any Lender Party demands compensation
under this Section 10.3, EnergySolutions
may at any time, upon at least five (5) Business Days’ prior notice to
such Lender Party, prepay in full the then outstanding affected Eurodollar
Option Loans of such Lender Party, together with accrued interest thereon to
the date of prepayment, along with any reimbursement required under Section 2.11 hereof. 
Concurrently with prepaying such Eurodollar Option Loans, notwithstanding
anything contained in Article 2
or Article 3 hereof, EnergySolutions
may borrow a Base Rate Option Loan from such Lender Party, and such Lender
Party shall, if so requested, make such Base Rate Option Loan in an amount such
that the outstanding principal amount held by such Lender Party shall equal the
outstanding principal amount immediately prior to such prepayment.

 

(c)                                  If
any Lender requests compensation under this Section 10.3,
then EnergySolutions may, at its sole expense and effort, upon notice to such
Lender and the Administrative Agent, require such Lender to assign and delegate,
without recourse (in accordance with and subject to the restrictions contained
in, and consents required by, Section 11.5),
all of its interests, rights and obligations under this Agreement and the
related Loan Documents to an assignee that shall assume such obligations (which
assignee may be another Lender, if a Lender accepts such assignment); provided
that:  (i) EnergySolutions shall
have paid to the Administrative Agent the assignment fee specified in Section 11.5, (ii) such Lender shall have received
payment of an amount equal to the outstanding principal of and premium (if any)
on its Loans, accrued interest thereon, accrued fees and all other amounts
payable to it hereunder and under the other Loan Documents (including any
amounts Section 2.11, treating such
assignment as a voluntary prepayment) from the assignee (to the extent of such
outstanding principal and accrued interest and fees) or EnergySolutions (in the
case of all other amounts); (iii) such assignment will result in a reduction
in such compensation or payments thereafter; and (iv) such assignment does
not conflict with Applicable Law.  A
Lender shall not be required to make any such assignment or delegation if,
prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances
entitling EnergySolutions to require such assignment and delegation cease to
apply.  Each Lender agrees that, if
EnergySolutions elects to replace such Lender in accordance with this Section,
it shall promptly execute and deliver to the Administrative Agent an Assignment
and Assumption to evidence such sale and purchase and shall deliver to the Administrative
Agent any Note (if Notes have been issued in respect of such Lender’s Loans)
subject to such Assignment and Assumption; provided that the failure of
any such non-consenting Lender to execute an

 

114

 

Assignment and
Assumption shall not render such sale and purchase (and the corresponding
assignment) invalid and such assignment shall be recorded in the Register.

 

Section 10.4                                Effect
on Other Loans.

 

(a)                                  If
notice has been given pursuant to Section 10.1,
10.2 or 10.3
suspending the obligation of any Lender to make or continue Eurodollar Option
Loans, or requiring Eurodollar Option Loans of any Lender to be repaid or
prepaid, then, unless and until such Lender notifies EnergySolutions that the
circumstances giving rise to such repayment no longer apply, all Loans which
would otherwise be made or continued as Eurodollar Option Loans shall, at the
option of EnergySolutions, be made or continued instead as Base Rate Option
Loans.

 

(b)                                 If,
with respect to any Eurodollar Option Loan, Lenders owed at least 51% of the
then aggregate unpaid principal amount thereof notify the Administrative Agent
that the Eurodollar Rate for any Interest Period for such Loan will not
adequately reflect the cost to such Lenders of making, funding or maintaining
their Eurodollar Option Loans for such Interest Period, the Administrative
Agent shall forthwith so notify EnergySolutions and the Lenders which have made
such Loan, whereupon (i) such Eurodollar Revolving Loan will automatically,
on the last day of the then existing Interest Period therefor, be reborrowed as
a Base Rate Revolving Loan, (ii) such Eurodollar Term Loan will automatically,
on the last day of the then existing Interest Period therefor, be continued as
a Base Rate Term Loan and (iii) the obligation of the Lenders which have
made such Loan to make further or continue Eurodollar Option Loans shall be
suspended until the Administrative Agent shall notify EnergySolutions that such
Lenders have determined that the circumstances causing such suspension no
longer exist.

Section 11.2                                Costs
and Expenses.

 

(a)                                  EnergySolutions
will promptly pay, or reimburse, without duplication:

 

(i)                                     all
reasonable out-of-pocket expenses of the Administrative Agent or the Collateral
Agent in connection with the preparation, structuring, due diligence,
negotiation, execution, delivery, syndication and administration of this
Agreement and the other Loan Documents and the transactions related hereto,
contemplated hereunder and thereunder and the making of the initial Loans
hereunder (whether or not such Loans are made), including, but not limited to,
the reasonable fees and disbursements of Cahill Gordon & Reindel LLP,
special counsel for the Arrangers;

 

(ii)                                  all
reasonable out-of-pocket expenses of the Administrative Agent or the Collateral
Agent in connection with the administration of the transactions contemplated in
this Agreement or the other Loan Documents, the restructuring and “work out” of
such transactions and the preparation, negotiation, execution and delivery of
any waiver, amendment or consent, whether or not such waiver, amendment or
consent shall become effective, by the Administrative Agent and the Lender
Parties relating to this Agreement or the other Loan Documents, including, but
not limited to, the reasonable fees and disbursements of any experts, agents or
consultants and of special counsel for the Administrative Agent or the
Collateral Agent (limited to one outside counsel to the Administrative Agent
and the Collateral Agent and such local counsel as may be necessary for the
Administrative Agent and the Collateral Agent), but excluding any assignment
fee pursuant to Section 11.5(b) hereof;
and

 

(iii)                               all
out-of-pocket costs and expenses of the Administrative Agent or the Collateral
Agent and the Lenders in connection with the enforcement of this Agreement or
the other Loan Documents and all out-of-pocket costs and expenses of collection
if an Event of Default occurs in the payment of the Loans or the other Obligations,
whether in any action, suit or litigation, or any bankruptcy, insolvency,
liquidation, or other similar proceeding affecting creditors’ rights generally,
which in each case shall include reasonable fees and out-of-pocket expenses of
one respective outside counsel and such local counsel as may be necessary for
the Administrative Agent, the Collateral Agent and the Lenders.

 

(b)                                 EnergySolutions
also agrees not to assert any claim against any Agent, any Lender Party or any
of their Affiliates, or any of their respective officers, directors, employees,
agents and advisors, on any theory of liability, for special, indirect,
consequential or punitive damages arising out of or otherwise relating to the
Commitments, the actual or proposed use of the proceeds of any Loan or Letter
of Credit, the Loan Documents or any of the transactions contemplated by the
Loan Documents.

 

(c)                                  If
any Loan Party fails to pay when due any costs, expenses or other amounts

expenses of counsel and indemnities, such amount may be paid on behalf of such
Loan Party by the Administrative Agent.

 

Section 11.3                                Waivers.

 

The rights and
remedies of the Administrative Agent, the Collateral Agent and the Lender
Parties under this Agreement and the other Loan Documents shall be cumulative
and not exclusive of any rights or remedies which they would otherwise
have.  No failure or delay by the
Administrative Agent, the Collateral Agent or the Lender Parties, or any of
them, in exercising any right shall operate as a waiver of such right.  The Administrative Agent and the Lender
Parties expressly reserve the right to require strict

 

117

 

compliance
with the terms of this Agreement in connection with any future funding of a request
for a Loan.  In the event the Lender
Parties decide to fund a Loan or issue a Letter of Credit at a time when EnergySolutions
is not in strict compliance with the terms of this Agreement, such decision by
the Lender Parties shall not be deemed to constitute an undertaking by the
Lender Parties to fund any further Loans, to issue any further Letter of Credit
or to preclude the Lender Parties and the Administrative Agent from exercising
any rights available under the Loan Documents or at law or equity.  Any waiver or indulgence granted by the
Administrative Agent, the Lender Parties or the Majority Lenders shall not
constitute a modification of this Agreement, except to the extent expressly
provided in such waiver or indulgence, or constitute a course of dealing at
variance with the terms of this Agreement such as to require further notice of
their intent to require strict adherence to the terms of this Agreement in the
future.

 

Section 11.4                                Set-Off.

 

In addition to
any rights now or hereafter granted under Applicable Law and not by way of limitation
of any such rights, upon the occurrence of an Event of Default and during the
continuation thereof, the Administrative Agent and the Lender Parties are
hereby authorized by EnergySolutions at any time or from time to time, without
notice to EnergySolutions or to any other Person, any such notice being hereby
expressly waived, to set off and to appropriate and to apply any and all
deposits (general or special, time or demand, including, but not limited to,
Indebtedness evidenced by certificates of deposit, in each case whether matured
or unmatured) and any other Indebtedness at any time held or owing by any
Lender Party or the Administrative Agent to or for the credit or the account of
EnergySolutions or any of its Subsidiaries against and on account of the
Obligations irrespective of whether (a) any Lender Party or the
Administrative Agent shall have made any demand hereunder or (b) the Administrative
Agent shall have declared the principal of and interest on the Loans and other
amounts due hereunder to be due and payable as permitted by Section 8.2 and although such Obligations or any of
them shall be contingent or unmatured. 
Upon direction by the Administrative Agent with the consent of the
Majority Lenders, each Lender Party holding deposits of EnergySolutions or any
of its Subsidiaries shall exercise its set-off rights as so directed.

 

Section 11.5                                Binding
Effect and Assignment.

 

(a)                                  This
Agreement shall become effective when it shall have been executed by EnergySolutions
and each Agent and the Administrative Agent shall have been notified by each
Lender party hereto, and EnergySolutions shall have been notified by the Administrative
Agent, that each such Lender party hereto has executed it and thereafter shall
be binding upon and inure to the benefit of EnergySolutions, each Agent and
each such Lender and their respective successors and assigns, except that
EnergySolutions shall not have the right to assign its rights hereunder or any
interest herein without the prior written consent of all of the Lenders.

 

(b)                                 Each
Lender may enter freely into participation agreements with respect to or
otherwise grant participations in its Loans to one or more banks or other
lenders or financial institutions; provided, however, that (i) such
Lender’s obligations hereunder shall remain unchanged, (ii) such Lender
shall remain solely responsible to the other parties hereto for the performance
of such obligations, (iii) the participant shall not be entitled by the
benefit of its participation to vote or otherwise take action under this
Agreement or any other Loan Document, except with respect to the matters
referred to in Section 11.12 hereof relating
to the matters in which affected Lenders are required to vote or all Lenders
are required to vote, (iv) such Lender shall deliver to the Administrative
Agent and EnergySolutions (in such number of copies as shall be reasonably
requested by the recipient) duly signed and properly completed copies of 

 

118

 

Internal
Revenue Service Form W-8 IMY (or any successor thereto) for each
participant, and (v) EnergySolutions shall continue to deal solely and
directly with such Lender in connection with such Lender’s rights and
obligations hereunder.  In addition, each
Lender may sell up to 100%, assign or create a security interest in all or any
portion of its rights hereunder and under the other Loan Documents to any other
Person on an assignment basis; provided that (A) (I) at any
time hereunder, such assignment is to an Affiliate of the assignor, an Approved
Fund, another Lender or any Conduit Lender, (II) prior to a date to be
separately agreed among EnergySolutions, Parent and the Arranger (the “Syndication
Date”), such assignment is made by the Administrative Agent in connection
with syndication of any of the Loans, (III) prior to the Syndication Date,
the Administrative Agent has given its written consent to the proposed assignee
of a Lender hereunder or (IV) after the Syndication Date, EnergySolutions
(unless there exists at the time of such assignment an Event of Default
hereunder) and the Administrative Agent have given their prior written consent
to the proposed assignee of a Lender hereunder, which consents shall not be
unreasonably delayed, conditioned or withheld, and (B) each such assignment
shall be in a principal amount of not less than the lesser of (I) the
entire amount of such Lender’s interest hereunder or (II) $1,000,000
(calculated for the Term Loans and the Term L/C Facility Loans on a combined
basis with such Lender’s contemporaneous assignment of its Duratek Loans)
unless an assignment is from one Lender to another or to an Approved Fund or an
Affiliate of a Lender, in which case there shall be no minimum assignment
amount.  Each Lender who sells or assigns
a portion of its Loans pursuant hereto shall pay to the Administrative Agent an
assignment fee of $3,500 with respect to each assignment (except that one such
fee shall be payable in connection with simultaneous assignments (i) to or
by two or more Approved Funds and (ii) of Duratek Loans), such fee to be
paid to the Administrative Agent not later than the effective date of the
assignment of the Loan relating thereto. 
All assignments by any of the Lenders of any interests hereunder shall
be made pursuant to an Assignment and Acceptance.  Each Lender may provide any proposed
participant or assignee with confidential information provided to such Lender
regarding EnergySolutions, Parent and the Subsidiaries on a confidential basis,
and such participant or assignee shall agree to maintain such confidentiality
in accordance with the provisions of Section 11.19
hereof.  Further, each permitted assignee
or participant with respect to any portion of the Loans shall be entitled to
the benefits, and subject to the burdens, of Sections
2.11, 2.13, 2.14
and Article 10 hereof and all other provisions
hereof and of the other Loan Documents as a “Lender” hereunder.  Each Participant shall be entitled to the
benefits of Sections 2.11, 2.13 and 2.14 and Article 10 (subject to the requirements of those
Sections) to the same extent as if it were a Lender, but no participant shall
be entitled to a greater payment under Section 2.14
than the applicable Lender would have been entitled to receive with respect to
the participation sold.  Upon the grant
of a participation of its commitment by a Lender pursuant to this Section 11.5(b), such Lender (on behalf of EnergySolutions)
shall maintain a register analogous to the Register described in Section 11.5(c) below.  Notwithstanding anything to the contrary set
forth herein, each assignment by a Lender of its Term Loans or Term L/C
Facility Loans hereunder shall be made concurrently with the ratable assignment
of all or a portion of such Lender’s (i) Duratek Loans, (ii) Term L/C
Facility Loans or (iii) Term Loans, as applicable, and no assignment of
the Term Loans or Term L/C Facility Loans shall be made by any Lender hereunder
unless such Lender makes a simultaneous ratable assignment of all or a portion
of its Duratek Loans and its Term L/C Facility Loans or Term Loans, as
applicable; provided that immaterial deviations of the ratable
assignment provisions in this Section 11.5(b) shall
be permitted.  Before and after any
assignment of Term Loans or Term L/C Facility Loans by any Lender, the ratios
of (i) such Lender’s Term Loans to the aggregate principal amount of Term
Loans outstanding, (ii) such Lender’s Term L/C Facility Loans to the
aggregate amount of Term L/C Facility Loans and (iii) such Lender’s
Duratek Loans to the aggregate principal amount of Duratek Loans outstanding,
shall be identical; provided that immaterial deviations of the ratable
assignment provisions in this Section 11.5(b) shall
be permitted.

 

(c)                                  The
Administrative Agent, acting for this purpose as an agent of EnergySolutions,
shall maintain a copy of each Assignment and Acceptance delivered to it and a
register for the recordation of 

 

119

 

the names and
addresses of the Lenders and the Commitments of and the principal amount of the
Loans owing to each Lender pursuant to the terms hereof from time to time (the “Register”).  The entries in the Register shall be conclusive,
absent manifest error, and EnergySolutions, the Administrative Agent and the
Lenders shall treat each Person whose name is recorded in the Register pursuant
to the terms hereof as a Lender hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. 
The Register shall be available for inspection at the offices of the
Administrative Agent by EnergySolutions or any Lender, at any reasonable time
during normal business hours and from time to time upon reasonable prior
notice.  Each Lender agrees to provide
the Administrative Agent and EnergySolutions with written notice of the
assignment of all or part of its rights hereunder.  Upon the Administrative Agent’s receipt of a
duly completed Assignment and Acceptance executed by an assigning Lender and an
assignee Lender, the assignee’s completed administrative questionnaire (unless
the assignee is already a Lender), the fee referred to in Section 11.5(b) above
and any written consent to such assignment required thereby, the Administrative
Agent shall accept such Assignment and Acceptance and record the information
contained therein in the Register.  No
assignment shall be effected for purposes of this Agreement unless it has been
recorded in the Register as provided in this paragraph.  In connection with each assignment of Term
L/C Facility Loans, the Term L/C Facility Loan of the assignor Lender shall not
be released, but shall instead be purchased by the relevant assignee and
continue to be held for application (to the extent not already applied) in
accordance with Article 2 to satisfy such
assignee’s obligations in respect of Term L/C Facility Letters of Credit.  Each Term L/C Facility Lender agrees that
immediately prior to each assignment by a Term L/C Facility Lender (i) the
Administrative Agent shall establish a new Term L/C Facility Collateral
Sub-Account in the name of the assignee, (ii) unless otherwise consented
to by the Administrative Agent, a corresponding portion of the Term L/C
Facility Loan credited to the Term L/C Facility Collateral Sub-Account of the
assignor Lender shall be purchased by the assignee and shall be transferred
from the assignor’s Term L/C Facility Collateral Sub-Account to the assignee’s
Term L/C Facility Collateral Sub-Account and (iii) if after giving effect
to such assignment the Term L/C Facility Loan of the assignor Lender shall be
zero, the Administrative Agent shall close the Term L/C Facility Collateral
Sub-Account of such assignor Lender.

 

(d)                                 Notwithstanding
anything to the contrary contained in this Section 11.5,
any Lender that is a fund that invests in bank loans may (without the consent
of EnergySolutions or the Administrative Agent) pledge all or a portion of its
rights in connection with this Agreement to the trustee or any holder of
obligations or agents therefor owed, or securities issued, by such fund as security
for such obligations or securities.  No
pledge described in the immediately preceding sentence shall release any such
Lender from its obligations hereunder.

 

(e)                                  The
Revolving Issuing Bank may assign to an assignee all of its rights and
obligations under the undrawn portion of its Revolving Letter of Credit
Commitment at any time; provided, however, that (i) each
such assignment shall be made in accordance with clause (A) of the second
proviso in Section 11.5(b) and (ii) the
parties to each such assignment shall execute and deliver to the Administrative
Agent, for its acceptance and recording in the Register, an Assignment and
Acceptance, together with a processing and recordation fee of $3,500.  The Revolving Issuing Bank shall promptly
notify EnergySolutions of such Assignment.

 

(f)                                    Except
as specifically set forth in Section 11.5(b) hereof,
nothing in this Agreement or any Notes, express or implied, is intended to or
shall confer on any Person other than the respective parties hereto and thereto
and their successors and assignees permitted hereunder and thereunder any
benefit or any legal or equitable right, remedy or other claim under this
Agreement or any Notes.

 

(g)                                 The
provisions of this Section 11.5
shall not apply to any purchase of participations among the Lenders pursuant to
Section 2.12 hereof.

 

120

 

(h)                                 Notwithstanding
anything to the contrary contained herein, any Lender Party (a “Granting
Lender”) may grant to a special purpose funding vehicle identified as such
in writing from time to time by the Granting Lender to the Administrative Agent
and EnergySolutions (a “Conduit Lender”) the option to provide all or
any part of any Loan that such Granting Lender would otherwise be obligated to
make pursuant to this Agreement; provided that (i) nothing herein
shall constitute a commitment by any Conduit Lender to fund any Loan, and (ii) if
a Conduit Lender elects not to exercise such option or otherwise fails to make
all or any part of such Loan, the Granting Lender shall be obligated to make
such Loan pursuant to the terms hereof. 
The making of a Loan by a Conduit Lender hereunder shall utilize the applicable
Commitment of the Granting Lender to the same extent, and as if, such Loan were
made by such Granting Lender.  Each party
hereto hereby agrees that (i) no Conduit Lender shall be liable for any indemnity
or similar payment obligation under this Agreement for which a Lender Party
would be liable, (ii) no Conduit Lender shall be entitled to the benefits
of Sections 2.13, 2.14
and 10.3 (or any other increased costs
protection provision) to any greater extent than the Granting Lender would have
been entitled absent the use of a Conduit Lender and (iii) the Granting
Lender shall for all purposes, including, without limitation, the approval of
any amendment or waiver of any provision of any Loan Document, remain the
Lender Party of record hereunder.  In
furtherance of the foregoing, each party hereto hereby agrees (which agreement
shall survive the termination of this Agreement) that, prior to the date that
is one year and one day after the payment in full of all outstanding commercial
paper or other senior Indebtedness of any Conduit Lender, it will not institute
against, or join any other Person in instituting against, such Conduit Lender
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceeding under the laws of the United States or any State thereof.  Notwithstanding anything to the contrary contained
in this Agreement, any Conduit Lender may (i) with notice to, but without
prior consent of, EnergySolutions and the Administrative Agent and without
paying any processing fee therefor, assign all or any portion of its interest
in any Loan to the Granting Lender and (ii) disclose on a confidential
basis any non-public information relating to its funding of advances to any rating
agency, commercial paper dealer or provider of any surety or guarantee or
credit or liquidity enhancement to such Conduit Lender.  This Section 11.5(h) may
not be amended without the prior written consent of each Granting Lender all or
any part of whose Loans are being funded by a Conduit Lender at the time of
such amendment.

 

(i)                                     Notwithstanding
any contrary provision of this Section 11.5,
any Lender may at any time pledge the Obligations held by it and such Lender’s
rights under this Agreement and the other Loan Documents to a Federal Reserve
Bank; provided that no such pledge to a Federal Reserve Bank shall release
such Lender from such Lender’s obligations hereunder or under any other Loan
Document.

 

Section 11.6                                Accounting
Principles.

 

Except as set
forth in the following sentence, references in this Agreement to GAAP shall be
to such principles as defined in Section 1.4,
and all accounting terms used herein without definition shall be used as
defined under GAAP.  All references to
Operating Cash Flow, Debt Service and other such terms shall be deemed to refer
to such items of EnergySolutions or Parent and their respective Subsidiaries on
a consolidated basis, consistently applied, unless otherwise indicated herein.

 

Section 11.7                                Counterparts.

 

This Agreement
may be executed in any number of counterparts, each of which shall be deemed to
be an original, but all such separate counterparts shall together constitute
but one and the same instrument.

Section 11.8                                Governing
Law and Jurisdiction.

AGREEMENT, ANY NOTES AND ANY LOAN DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE
WITH AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO
AGREEMENTS MADE AND TO BE PERFORMED IN NEW YORK.

(a)                                  In
no event shall the amount of interest due or payable hereunder or under any
Notes exceed the maximum rate of interest allowed by Applicable Law, and in the
event any such payment is inadvertently made by EnergySolutions or inadvertently
received by any Lender, then such excess sum shall be credited as a payment of
principal, unless EnergySolutions shall notify the Administrative Agent or such
Lender in writing that it elects to have such excess returned forthwith.  It is the express intent hereof that
EnergySolutions not pay and the Lenders not receive, directly or indirectly in

interest in excess of that which may legally be paid by EnergySolutions under Applicable
Law.

 

(b)                                 Notwithstanding
the use by the Lenders of the Base Rate, the Federal Funds Rate and the
Eurodollar Rate as reference rates for the determination of interest on the
Loans, the Lenders shall be under no obligation to obtain funds from any
particular source in order to charge interest to EnergySolutions at interest
rates related to such reference rates.

If, in
connection with any proposed change, waiver, discharge or termination of or to
any of the provisions of this Agreement (other than as contemplated by clause (b) above),
and the consent of all Lenders required hereunder would have been obtained but
for any Lender’s failure to consent (such Lender, a “Non-Consenting Lender”)
and the consent of Majority Lenders is obtained but the consent of one or more
of such other Lenders whose consent is required is not obtained, then
EnergySolutions shall have the right, so long as all Non-Consenting Lenders
whose individual consent is required are treated as described in either clause (i) or
(ii) below, to either (i) replace each such Non-Consenting Lender or
Lenders (or, at the option of EnergySolutions if the respective Lender’s
consent is required with respect to less than all Loans (or related Commitments
or Synthetic Deposits), to replace only the Commitments, Synthetic Deposits
and/or Loans of the respective Non-Consenting Lender that gave rise to the need
to obtain such Lender’s individual consent) with one or more assignees pursuant
to, and with the effect of an assignment under, Section 10.3
so long as at the time of such replacement, each such assignee consents to the
proposed change, waiver, discharge or termination or (ii) terminate such
Non-Consenting Lender’s Commitment (if such Lender’s consent is required as a
result of its Commitment) and/or repay all outstanding Loans or refund the
Synthetic Deposit of such Lender that gave rise to the need to obtain such
Lender’s consent in accordance with this Agreement; provided that,
unless the Commitments that are terminated, Loans that are repaid and Synthetic
Deposit that is refunded pursuant to the preceding clause (ii) are immediately
replaced in full at such time through the addition of new Lenders or the
increase of the Commitments and/or outstanding Loans of existing Lenders (who
in each case must specifically consent thereto), then in the case of any action
pursuant to the preceding clause (ii), the Majority Lenders (determined after
giving effect to the proposed action) shall specifically consent thereto.  In addition, any waiver, amendment or
modification of this Agreement that by its terms affects the rights or duties
under this Agreement of the Revolving Lenders (but not the Term Lenders or
Synthetic Lenders) or the Term Lenders (but not the Revolving Lenders or
Synthetic Lenders) or the Synthetic Lenders (but not the Term Lenders or the
Revolving Lenders) may be effected by an agreement or agreements in writing
entered into by EnergySolutions and the requisite percentage in interest of the
affected class of Lenders that would be required to consent thereto under this Section 11.12 if such Lenders were the only Lenders
hereunder at the time; provided  further that EnergySolutions
shall pay to any Non-Consenting Lender any premium that would be payable in the
event of a prepayment on such date.

to any litigation to which any Loan Party, any Agent, any Lender Party or any
of their Affiliates is a party.  In no
event shall any Lender Party be obligated or required to return any materials
furnished to it by EnergySolutions.  The
foregoing provisions shall not apply to a Lender Party with respect to information

through a breach of this Section 11.19
by such Lender Party), (ii) is already in the possession of such Lender
Party on a nonconfidential basis, or (iii) comes into the possession of
such Lender Party in a manner not known to such Lender Party to involve a

Section 11.20                          No
Liability of the Issuing Banks.

 

EnergySolutions
assumes all risks of the acts or omissions of any beneficiary or transferee of
any Letter of Credit with respect to its use of such Letter of Credit.  Neither the Issuing Banks nor any of their
officers or directors shall be liable or responsible for (a) the use that
may be made of any Letter of Credit or any acts or omissions of any beneficiary
or transferee in connection therewith; (b) the validity, sufficiency or
genuineness of documents, or of any endorsement thereon, even if such documents
should prove to be in any or all respects invalid, insufficient, fraudulent or
forged; (c) payment by either Issuing Banks against presentation of
documents that do not comply with the terms of a Letter of Credit, including
failure of any documents to bear any reference or adequate reference to the
Letter of Credit; or (d) any other circumstances whatsoever in making or
failing to make payment under any Letter of Credit, except that EnergySolutions
shall have a claim against the Issuing Banks, and the Issuing Banks shall be
liable to EnergySolutions, to the extent of any direct, but not consequential,
damages suffered by EnergySolutions that EnergySolutions proves were caused by (i) the
Issuing Banks’ willful misconduct, gross negligence or breach of any Loan
Document as determined in a final, non-appealable judgment by a court of competent
jurisdiction in determining whether documents presented under any Letter of
Credit comply with the terms of the Letter of Credit or (ii) the Issuing
Banks’ willful failure to make lawful payment under a Letter of Credit after
the presentation to it of a draft and certificates strictly complying with the
terms and conditions of the Letter of Credit. 
In furtherance and not in limitation of the foregoing, the Issuing Banks
may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary.

reasonable, such information and take such actions as are reasonably requested
by the Administrative Agent or any Lender Parties in order to assist the
Administrative Agent and the Lenders in maintaining compliance with the Patriot

Platform.

 

EnergySolutions
hereby agrees that it will provide to the Administrative Agent all information,
documents and other materials that it is obligated to furnish to the
Administrative Agent pursuant to the Loan Documents, including, without
limitation, all notices, requests, financial statements, financial and other
reports, certificates and other information materials, but excluding any such
communication that (i) relates to a request for a new, or a conversion of

payment of any principal or other amount due under this Agreement prior to the
scheduled date therefor, (iii) provides notice of any default or event of
default under this Agreement or (iv) is required to be delivered to

acceptable to the Administrative Agent to oploanswebadmin@citigroup.com.  In addition, EnergySolutions agrees to
continue to provide the Communications to the Administrative Agent in the

Administrative Agent.

 

EnergySolutions
further agrees that the Administrative Agent may make the Communications
available to the Lenders by posting the Communications on Intralinks or a
substantially similar electronic transmission systems (the “Platform”).

 

THE PLATFORM IS
PROVIDED “AS IS” AND “AS AVAILABLE.”  THE
AGENT PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF
THE COMMUNICATIONS, OR THE ADEQUACY OF THE PLATFORM AND EXPRESSLY DISCLAIM
LIABILITY FOR ERRORS OR OMISSIONS IN THE COMMUNICATIONS.  NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR
STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM
FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT PARTIES IN CONNECTION
WITH THE COMMUNICATIONS OR THE PLATFORM. 
IN NO EVENT SHALL THE ADMINISTRATIVE AGENT OR ANY OF ITS AFFILIATES OR
ANY OF THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR
REPRESENTATIVES (COLLECTIVELY, “AGENT PARTIES”) HAVE ANY LIABILITY TO
ENERGYSOLUTIONS, 

 

127

 

ANY LENDER
OR ANY OTHER PERSON OR ENTITY FOR DAMAGES OF ANY KIND, INCLUDING, WITHOUT
LIMITATION, DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES,
LOSSES OR EXPENSES (WHETHER IN TORT, CONTRACT OR OTHERWISE) ARISING OUT OF
ENERGYSOLUTIONS’ OR THE ADMINISTRATIVE AGENT’S TRANSMISSION OF COMMUNICATIONS
THROUGH THE INTERNET, EXCEPT TO THE EXTENT THE LIABILITY OF ANY AGENT PARTY IS
FOUND IN A FINAL NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION
TO HAVE RESULTED PRIMARILY FROM SUCH AGENT PARTY’S GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT.

 

The
Administrative Agent agrees that the receipt of the Communications by the
Administrative Agent at its e-mail address set forth above shall constitute
effective delivery of the Communications to the Agent for purposes of the Loan
Documents.  Each Lender agrees that
notice to it (as provided in the next sentence) specifying that the
Communications have been posted to the Platform shall constitute effective
delivery of the Communications to such Lender for purposes of the Loan
Documents.  Each Lender agrees to notify
the Administrative Agent in writing (including by electronic communication)
from time to time of such Lender’s e-mail address to which the foregoing notice
may be sent by electronic transmission and (ii) that the foregoing notice
may be sent to such e-mail address.

 

Nothing herein
shall prejudice the right of the Administrative Agent or any Lender to give any
notice or other communication pursuant to any Loan Document in any other manner
specified in such Loan Document.

 

Section 11.24                          Conversion
of Currencies.

 

(i)                                     If,
for the purpose of obtaining judgment in any court, it is necessary to convert
a sum owing hereunder in one currency into another currency, each party hereto
agrees, to the fullest extent that it may effectively do so, that the rate of
exchange used shall be that at which in accordance with normal banking
procedures in the relevant jurisdiction the first currency could be purchased
with such other currency on the Business Day immediately preceding the day on
which final judgment is given.

 

(ii)                                  The
obligations of EnergySolutions in respect of any sum due to any party hereto or
any holder of the obligations owing hereunder (the “Applicable Creditor”)
shall, notwithstanding any judgment in a currency (the “Judgment Currency”)
other than the currency in which such sum is stated to be due hereunder (the “Agreement
Currency”), be discharged only to the extent that, on the Business Day
following receipt by the Applicable Creditor of any sum adjudged to be so due
in the Judgment Currency, the Applicable Creditor may in accordance with normal
banking procedures in the relevant jurisdiction purchase the Agreement Currency
with the Judgment Currency; if the amount of the Agreement Currency so purchased
is less than the sum originally due to the Applicable Creditor in the Agreement
Currency, EnergySolutions agrees, as a separate obligation and notwithstanding
any such judgment, to indemnify the Applicable Creditor against such loss.  The obligations of EnergySolutions contained
in this Section 11.24 shall survive the
termination of this Agreement and the payment of all other amounts owing hereunder.

 

(iii)                               For
purposes of this Agreement, the Dollar Equivalent of the Available Amount of
any Letter of Credit shall be calculated on the date when such Letter of Credit
is issued, on the first Business Day of each month and at such other times as
designated by the Administrative Agent. 
Such Dollar Equivalent shall remain in effect until the same is
recalculated by the Administrative Agent as provided 

 

128

 

above and notice of such recalculation is
received by EnergySolutions, it being understood that until such notice is
received, the Dollar Equivalent shall be as last reported by the Administrative
Agent to EnergySolutions.  The
Administrative Agent shall promptly notify EnergySolutions of each such determination
of Dollar Equivalents.

proposed amendments to the Second Amended and Restated Credit Agreement as
contemplated by that certain amendment agreement, of even date herewith, by and
among EnergySolutions, LLC, ENV Holdings LLC, the lenders party from time to
time thereto, CGMI and CNAI.

 

SECTION 3.                                Amendment
Effective Date

 

The Amendments shall become effective upon
the satisfaction or waiver by the Administrative Agent of (i) the
condition precedent set forth in Section 5 hereto, (ii) each
of the conditions precedent set forth in Section 3.1 of the Amended
and Restated Credit Agreement and (iii) the Administrative Agent’s
receipt, on or prior to the Consent Receipt Date, of executed counterparts
hereof (which need not be originals) executed on behalf of the Majority Lenders
(the first date as of which all each such conditions have been satisfied is
herein called the “Amendment Effective Date”).

 

SECTION 4.                                Fees

 

No later than
ten (10) business days after the Administrative Agent has received
executed counterparts hereof (which need not be originals) executed on behalf
of the Majority Lenders, EnergySolutions shall deliver, by wire transfer of
immediately available funds, to the Administrative Agent for the account of
each Lender who, prior to the Consent Receipt Date, delivers an executed
counterpart hereof (which need not be an original) and consents to the
Amendments, an amendment fee (the “Amendment Fee”) in dollars in an
amount equal to 0.50% of the aggregate principal amount of Loans held by such
Lender under the Existing Credit Agreement. 
For the sake of clarity, all Amendment Fees owed pursuant to this Section 4  shall be due and payable regardless of whether (i) the
condition to effectiveness described in Section 5 hereto has been
satisfied, (ii) the Amended and Restated Credit Agreement has or will
become effective and (ii) the Acquisition has been or will be consummated.

such is superseded by the Amended and Restated Credit Agreement and each other
Loan Document that is being amended and restated or otherwise modified in
connection therewith.

 

(c)            The execution, delivery and
effectiveness of this Amendment Agreement shall not, except as expressly
provided herein, operate as a waiver of any right, power or remedy of the Lenders,
EnergySolutions or the Administrative Agent under any of the Loan Documents,
nor constitute a waiver or amendment of any other provision of any of the Loan
Documents.

 

(d)           This Amendment is a Loan Document.

Loans

 

Section 2.1             The Loans.

 

(a)           [Reserved].

 

(b)           The Loans.   The Lenders who have agreed to make Loans
agree, severally in accordance with their respective Commitments as set forth
on Schedule 4 hereof and not jointly, upon the terms and subject to the
conditions of this Agreement, to lend to Duratek, on the Original Agreement
Date, an aggregate amount equal to $240,000,000.  Amounts borrowed under this Section 2.1(b) and repaid or prepaid may not be
reborrowed.

 

(c)           [Reserved].

 

Section 2.2             Manner of Borrowing and Disbursement.

 

(a)           Choice of Interest Rate, Etc.  (i)  Any Loan shall, at the option of
Duratek, bear interest as a Base Rate Loan, or, subject to Section 2.2(a)(ii) and
Article 10 hereof, a Eurodollar
Loan.  Any notice given to the Administrative
Agent in connection with a requested Loan hereunder shall be given to the
Administrative Agent prior to 12:30 p.m. (New York time) in order for such
Business Day to count toward the minimum number of Business Days required.

 

(ii)           (A)  On the date on
which the aggregate unpaid principal amount of any Eurodollar Loan shall be
reduced, by payment or prepayment or otherwise, to less than $5,000,000, such
Eurodollar Loan shall automatically, on the last day of the then existing
Interest Period therefor, be continued as a Base Rate Loan.

 

(B)           If Duratek shall fail to select the duration of any
Interest Period for any Eurodollar Loan in accordance with the provisions
contained in the definition of “Interest Period” in Section 1.1,
the Administrative Agent will forthwith so notify Duratek and the
Lenders which have made such Eurodollar Loan, whereupon each such Eurodollar
Loan shall automatically, on the last day of the then existing Interest Period
therefor, be continued as a Base Rate Loan.

 

(C)           Upon the occurrence and during the continuance of
any Default, (1) each Eurodollar Loan will automatically, on the last day
of the then existing Interest Period therefor, be continued as a Base Rate
Loan, and (2) the obligation of the Lenders to continue any Eurodollar
Loan shall be suspended.

 

(b)           Base Rate Loans.

 

(i)            Initial Loans.  The initial Base Rate Loans were issued on
the Original Agreement Date.

 

(ii)           [Reserved].

 

(iii)          Continuations of Base Rate
Loans.  Upon at least one (1), with
respect to items (B) and (C) of this sentence, or three (3), with
respect to item (A) of this sentence, Business Days’ irrevocable prior
written notice to the Administrative Agent, Duratek shall specify whether all
or a portion of each Base Rate Loan outstanding on the related Payment Date (A) is
to be continued in whole or in part as one 

 

25

 

or more Eurodollar Loans for the Interest
Period(s) selected, (B) is to be continued in whole or in part as one
or more Base Rate Loans, or (C) is to be repaid and not reborrowed.

 

(c)           Eurodollar Loans.

 

(i)            Initial Loans.  Duratek shall give the Administrative Agent
in the case of any initial Eurodollar Loan at least three (3) Business Days’
irrevocable prior written notice in the form of a Request for Loan or Request
for Loan Eurodollar Basis, or telephonic notice followed immediately by a Request
for Loan or Request for Loan Eurodollar Basis; provided, however,
that Duratek’s failure to confirm any telephonic notice with a Request for Loan
or Request for Loan Eurodollar Basis shall not invalidate any notice so
given.  The Administrative Agent, whose
determination shall be conclusive absent manifest error, shall determine the
available Eurodollar Basis and shall notify Duratek of such Eurodollar
Basis.  Duratek shall promptly notify the
Administrative Agent by telephone or telecopy, and shall immediately confirm
any such telephonic notice in writing, of its selection of a Eurodollar Basis
and Interest Period for such Loan; provided, however, that
Duratek’s failure to confirm any such telephonic notice in writing shall not invalidate
any notice so given.

 

(ii)           [Reserved].

 

(iii)          Continuations of Eurodollar
Loans.  Upon at least one (1), with
respect to items (B) and (C) of this sentence, or three (3), with
respect to item (A) of this sentence, Business Days’ irrevocable prior
written notice to the Administrative Agent, Duratek shall specify whether all
or a portion of each Eurodollar Loan outstanding on the related Payment Date (A) is
to be continued in whole or in part as one or more Eurodollar Loans for the
Interest Period(s) selected, (B) is to be continued in whole or in
part as a Base Rate Loan, or (C) is to be repaid and not reborrowed.

 

(d)           [Reserved].

 

(e)           Disbursement.

 

(i)            [Reserved].

 

(ii)           Unless the Administrative
Agent shall have received notice from a Lender prior to 2:30 p.m. (New
York time) on the date of any Loan that such Lender will not make available to
the Administrative Agent such Lender’s ratable portion of such Loan, the
Administrative Agent may assume that such Lender has made or will make such
portion available to the Administrative Agent on the date of such Loan and the
Administrative Agent may in its sole discretion and in reliance upon such assumption,
make available to Duratek on such date a corresponding amount.  If and to the extent the Lender does not make
such ratable portion available to the Administrative Agent, such Lender agrees
to repay to the Administrative Agent on demand such corresponding amount
together with interest thereon, for each day from the date such amount is made
available to Duratek until the date such amount is repaid to the Administrative
Agent, at the Federal Funds Rate for the first three (3) days and
thereafter at the Federal Funds Rate plus one percent (1%).

 

(iii)          If such Lender shall repay
to the Administrative Agent such corresponding amount, such amount so repaid
shall constitute such Lender’s portion of the applicable Loan for purposes of
this Agreement.  If such Lender does not
repay such corresponding amount immediately upon the Administrative Agent’s
demand therefor, the Administrative Agent shall notify Duratek and Duratek
shall immediately pay such corresponding amount to the Administrative Agent,
together with interest thereon.  The
failure of any Lender to fund its portion of any Loan shall not relieve any
other Lender of its obligation 

 

26

 

hereunder to fund its respective portion of
the Loan on the date of such borrowing, but no Lender shall be responsible for
any such failure of any other Lender.

 

(iv)          In the event that, at any
time when Duratek is not in Default and has satisfied all applicable conditions
set forth in Article 3 hereof, a Lender
for any reason fails, refuses, or has given notice to the Administrative Agent
and/or Duratek that it refuses to fund its portion of a Loan (a “Defaulting
Lender”), then, until such time as such Defaulting Lender has funded its
portion of such Loan, or all other Lenders have received payment in full
(whether by repayment or prepayment) of the principal and interest due in
respect of such Loan, such Defaulting Lender shall not have the right (i) to
vote regarding any issue on which voting is required or advisable under this
Agreement or any other Loan Document, and such Lender’s interest in any Loans
shall not be counted as outstanding for purposes of determining “Majority
Lenders” hereunder or (ii) to receive payments of principal, interest or
fees from Duratek in respect of its unfunded portion of Loans.  The provisions of this Section 2.2(e)(iv) are
not in lieu of any other claim Duratek may have against such Defaulting Lender.

 

Section 2.3             Interest.

 

(a)           On Base Rate Loans.  Interest on each Base Rate Loan shall be computed
on the basis of a year of 365/366 days for the actual number of days elapsed
and shall be payable at the Base Rate Basis for such Base Rate Loan, in arrears
on the applicable Payment Date for the period through the date immediately
preceding such Payment Date.  Interest on
Base Rate Loans then outstanding shall also be due and payable on the Maturity
Date.

 

(b)           On Eurodollar Loans.  Interest on each Eurodollar Loan shall be
computed on the basis of a 360-day year for the actual number of days elapsed
and shall be payable at the Eurodollar Basis for such Eurodollar Loan, in
arrears on the applicable Payment Date for the period through the day immediately
preceding such Payment Date, and, in addition, if the Interest Period for a
Eurodollar Loan exceeds three (3) months, interest on such Eurodollar Loan
shall also be due and payable in arrears on every three-month anniversary of
the first day of such Interest Period. 
Interest on Eurodollar Loans then outstanding shall also be due and
payable on the Maturity Date.

 

(c)           Interest if No Notice of
Selection of Interest Rate Basis.  With respect to any Loan, if Duratek fails to
give the Administrative Agent timely notice of its selection of a Eurodollar
Basis, or if for any reason a determination of a Eurodollar Basis for any Loan
is not timely concluded, the Base Rate Basis shall apply to such Loan.

 

(d)           Interest upon Default.  Immediately upon the occurrence of an Event
of Default hereunder, all overdue principal in respect of the Loans, together
with accrued and unpaid overdue interest, premium and other unpaid sums, shall
bear interest at the Default Rate.  Such
interest shall be payable on demand and shall accrue until the earliest of (a) waiver
or cure (to the satisfaction of the Lenders required under Section 11.12 hereof to waive or cure) of such Event of
Default, or (b) agreement by the Majority Lenders to rescind the charging
of interest at the Default Rate, or (c) payment in full of the Obligations.

 

(e)           Eurodollar Loans.  At no time may the number of outstanding
Eurodollar Loans exceed eight (8).

 

(f)            Applicable Margin.  The Applicable Margin shall be (i) 2.50%
for Eurodollar Loans (or 2.00% when the Leverage Ratio as of the most recently
completed fiscal quarter is less than 2.0 to 1.0) and (ii) 1.25% for Base
Rate Loans (or 1.00% when the Leverage Ratio as of the most recently completed
fiscal quarter is less than 2.0 to 1.0).

 

27

 

Section 2.4             Repayment.

 

Commencing September 30, 2006 and at the end of
each calendar quarter for the next 26 calendar quarters, the outstanding
principal balance of the Loans shall be repaid in an amount equal to the
product of the outstanding principal balance of the Loans as of the opening of
business on September 30, 2006 multiplied by 0.25%.  On June 7, 2013, the outstanding
principal balance of the Loans, if any, shall be repaid in full.  Notwithstanding anything to the contrary in
this Section 2.4, any unpaid principal
and interest of the Loans shall be due and payable in full on the Maturity
Date.

 

Section 2.5             [Reserved].

 

Section 2.6             Optional Prepayments and Application of
Prepayments.

 

(a)           Optional Prepayment of Loans.  Subject to Section 2.6(b),
the principal amount of any Base Rate Loan may be prepaid in full or
in part at any time, without penalty or premium and without regard to the
Payment Date for such Loan, upon not less than one (1) Business Day’s
prior written notice to the Administrative Agent of such prepayment.  Subject to Section 2.6(b) and Section 2.11, Eurodollar Loans may be prepaid prior to
the due date thereof, upon not less than three (3) Business Days’ prior
written notice to the Administrative Agent. 
Partial prepayments shall be in a principal amount of not less than
$1,000,000 and in an integral multiple of $500,000.  A notice of prepayment shall
be irrevocable.

 

(b)           Application of Prepayment.  Each prepayment of the Loans shall be applied
(i) first, in direct order of maturities, to the next four scheduled
principal repayment installments of the Term Facility and (ii) second, to
the other principal repayment installments of the Loans on a pro rata
basis.  The prepayment of any principal
amount of Loans shall be made with accrued interest to the date of such prepayment
on the aggregate principal amount prepaid and Duratek shall reimburse the
Lenders and the Administrative Agent, on demand, for any loss or out-of-pocket
expense incurred by any Lender or the Administrative Agent in connection with
such prepayment, as set forth in Section 2.11
hereof.  Any prepayment under this
Agreement shall not affect Duratek’s obligation to continue making payments
under any Secured Hedge Agreements, which shall remain in full force and effect
notwithstanding such prepayment, subject to the terms of such Secured Hedge
Agreements.

 

Section 2.7             [Reserved].

Proceeds (w) from any sale or disposition by Duratek or any of its
Subsidiaries of any interest in any Loan Party (other than from a sale to
another Loan Party), (x) except as set forth below, from any Permitted
Asset Sales by Duratek or any of its Subsidiaries (other than any Excluded

prepay the Loans, with application thereto in accordance with Section 2.6(b), in respective amounts equal to the
after-Tax amount of any refund, purchase price adjustment, claim or credit arising
under any agreement governing or relating to any acquisition of any assets or
business.  Notwithstanding the foregoing,
with respect to any Net Proceeds realized or received with respect to any
Permitted Asset Sales (other than any Excluded Asset Sales), at the option of
Duratek, and so long as no Default or Event of Default shall have occurred and
be continuing, Duratek may reinvest all or any portion of such Net Proceeds in 

 

28

 

assets used or useful for its business within
three hundred sixty-five (365) days following receipt of such Net Proceeds; provided,
however, that (i) if the property
subject to such asset sale constituted Collateral under the Security Documents,
then any capital assets purchased with the Net Proceeds thereof pursuant to
this subsection shall be mortgaged or pledged, as the case may be, to the
Administrative Agent, for the benefit of the Secured Parties, and (ii) if
any Net Proceeds are no longer intended to be so reinvested at any time after
delivery of a notice of reinvestment election, an amount equal to any such Net
Proceeds shall be immediately applied to the prepayment of the Loans in accordance
with Section 2.6(b).  For the purposes of this Section 2.8(a),
if EnergySolutions is a Subsidiary of Duratek, all references to Duratek and/or
its Subsidiaries (i) shall include Parent and/or its Subsidiaries but (ii) shall
not include EnergySolutions and/or its Subsidiaries.

 

(b)           In addition to the scheduled
repayments provided for in Section 2.4 hereof,
Duratek shall prepay the Loans in an amount equal to one hundred percent (100%)
of the Net Proceeds received after the Original Agreement Date from any
Indebtedness for Money Borrowed incurred by Duratek or any of its Subsidiaries,
except for Indebtedness for Money Borrowed (i) permitted by Section 7.1 hereof or (ii) incurred in connection
with any Permitted Investments or Permitted Acquisitions permitted under Section 7.6 hereof (including any Indebtedness assumed
by EnergySolutions or its respective Subsidiaries in connection with any such
Permitted Investment or Permitted Acquisition), to the extent that upon consummation
of any such Permitted Investment or Permitted Acquisition such Net Proceeds
were invested in, or used to acquire, such Permitted Investment or
Permitted Acquisition.  Such amount shall
be applied on the third Business Day following receipt thereof by EnergySolutions,
Parent or the affected Subsidiary in accordance with Section 2.6(b).    For the purposes of this Section 2.8(b),
if EnergySolutions is a Subsidiary of Duratek, all references to Duratek and/or
its Subsidiaries (i) shall include Parent and/or its Subsidiaries but (ii) shall
not include EnergySolutions and/or its Subsidiaries.

 

(c)           In addition to the scheduled

quarter ended September 30, 2006), on or prior to the fifth Business Day
following delivery of the financial statements required by Sections 6.1
and 6.2 hereof for the most recently completed fiscal quarter, (x) so
long as the Leverage Ratio as of the end of the most recently completed fiscal
quarter is equal to or greater than 3.0 to 1.0, Duratek shall prepay the Loans
in an amount equal to the difference between (i) fifty percent (50%) of
Excess Cash Flow for the most recently completed fiscal quarter and (ii) an
amount equal to the optional prepayments made pursuant to Section 2.6
in such fiscal period, (y) if the Leverage Ratio as of the end
of the most recently completed fiscal quarter is less than 3.0 to 1.0 and
greater than 1.0 to 1.0, Duratek shall prepay the Loans in an amount equal to
the difference between (i) twenty-five percent (25%) of Excess Cash Flow
for the most recently completed fiscal quarter and (ii) an amount equal to
the optional prepayments made pursuant to Section 2.6 in
such fiscal period and (z) if the Leverage Ratio as of the end of the most recently completed
fiscal quarter is less than or equal to 1.0 to 1.0, Duratek shall not be
required prepay the Loans.    For the
purposes of this Section 2.8(c), if EnergySolutions
is a Subsidiary of Duratek, all references to Duratek and/or its Subsidiaries (i) shall
include Parent and/or its Subsidiaries but (ii) shall not include
EnergySolutions and/or its Subsidiaries.

 

(d)           Any prepayment pursuant to
this Section 2.8 shall be made in the
manner set forth in Section 2.6(b).

 

Section 2.9             Evidence of Debt.

 

(a)           The Loans shall be repayable
in accordance with the terms and provisions set forth herein.  Upon the request of any Lender, Notes shall
be issued by Duratek and payable to the order of

 

29

 

such Lender reflecting such Lender’s
Loans.  The Notes issued by Duratek to
the Lenders shall be duly executed and delivered by one or more Authorized
Signatories.

 

(b)           Each Lender shall maintain
in accordance with its usual practice an account or accounts evidencing the
indebtedness of Duratek to such Lender resulting from each Loan owing to such
Lender from time to time, including the amounts of principal and interest payable
and paid to such Lender from time to time hereunder.

 

(c)           The Register maintained by
the Administrative Agent pursuant to Section 11.5(c) shall
include a control account, and a subsidiary account for each Lender, in which
accounts (taken together) shall be recorded (i) the date and amount of
each Loan made hereunder, the Type of such Loan and, if appropriate, the
Interest Period applicable thereto, (ii) the terms of each Assignment and
Acceptance delivered to and accepted by it, (iii) the amount of any
principal or interest due and payable or to become due and payable from Duratek
to each Lender hereunder, and (iv) the amount of any sum received by the Administrative
Agent from Duratek hereunder and each Lender’s share thereof.

 

(d)           Entries made in good faith
by the Administrative Agent in the Register pursuant to Section 2.9(c) above,
and by each Lender in its account or accounts pursuant to Section 2.9(b) above,
shall be prima facie evidence of the amount of principal and interest due and
payable or to become due and payable from Duratek to, in the case of the
Register, each Lender and, in the case of such account or accounts, such
Lender, under this Agreement, absent manifest error; provided, however,
that the failure of the Administrative Agent or such Lender to make an entry,
or any finding that an entry is incorrect, in the Register or such account or
accounts shall not limit or otherwise affect the obligations of Duratek under
this Agreement.

 

Section 2.10           Manner of Payment.

 

(a)           Each payment (including any
prepayment) by Duratek on account of the principal of or interest on the Loans,
commitment fees and any other amount owed to the Lenders, the Administrative
Agent or any of them under this Agreement shall be made not later than 2:00 p.m.
(New York time) on the date specified for payment under this Agreement to the
Administrative Agent at the Administrative Agent’s Account, for the account of
the Lenders, or the Administrative Agent, as the case may be, in lawful money
of the United States of America in immediately available funds without set-off
or counterclaim.  Any payment received by
the Administrative Agent after 2:00 p.m. (New York time) shall be deemed
received on the next Business Day. 
Receipt by the Administrative Agent of any payment hereunder at or prior
to 2:00 p.m. (New York time) on any Business Day shall be deemed to
constitute receipt on such Business Day. 
In the case of a payment for the account of a Lender, the Administrative
Agent will promptly thereafter (and, if such amount is received before 2:00 p.m.
(New York time), on the same day) distribute the amount so received in like
funds to such Lender.  If the Administrative
Agent shall not have received any payment from Duratek as and when due, the Administrative
Agent will promptly notify the Lenders accordingly.  Only upon its acceptance of an Assignment and
Acceptance and recording of the information contained therein in the Register
pursuant to Section 11.5(c), from and
after the effective date of such Assignment and Acceptance, the Administrative
Agent shall make all payments hereunder and under the Notes in respect of the
interest assigned thereby to the Lender assignee thereunder, and the parties to
such Assignment and Acceptance shall make all appropriate adjustments in
such payments for periods prior to such effective date directly between themselves.

 

(b)           Duratek agrees to pay
principal, interest, fees and all other Obligations due hereunder, under the
Fee Letter, under any Notes or under the other Loan Documents without set-off
or counterclaim or any deduction whatsoever (other than any deductions or withholdings
required by law on account of Taxes).

 

30

 

(c)           Prior to the acceleration of
the Loans under Section 8.2 hereof, if some
but less than all amounts due from Duratek are received by the Administrative
Agent with respect to the Obligations, the Administrative Agent shall
distribute such amounts in the following order of priority:

 

(i)            first, to the
payment of all of the fees, indemnification payments, costs and expenses that
are due and payable to the Administrative Agent (solely in its capacity as the
Administrative Agent) under or in respect of this Agreement and the other Loan
Documents on such date, ratably based upon the respective aggregate amounts of
all such fees, indemnification payments, costs and expenses owing to the Administrative
Agent on such date;

 

(ii)           second, to the
payment of all of the indemnification payments, costs and expenses that are due
and payable to the Lenders under or in respect of this Agreement and the other
Loan Documents on such date, ratably based upon the respective aggregate
amounts of all such indemnification payments, costs and expenses owing to the
Lenders on such date.

 

(iii)          third, to the
payment of fees and all of the accrued and unpaid interest and any premiums on
the Obligations of Duratek under or in respect of the Loan Documents that is
due and payable to the Administrative Agent and the Lenders, ratably based upon
the respective aggregate amounts of all such interest owing to the
Administrative Agent and the Lenders on such date;

 

(iv)          fourth, ratably to
the payment of the principal amount of all of the outstanding Loans that is due
and payable to the Administrative Agent and the Lenders on such date, ratably
based upon the respective aggregate amounts of all such principal owing to the
Administrative Agent and the Lenders on such date and amounts payable under
Secured Hedge Agreements with Lenders and/or their Affiliates (or Persons that
were Lenders or Affiliates of Lenders at the time any such Secured Hedge Agreement
was entered into);

 

(v)           fifth, to the
payment of all other Secured Obligations of the Loan Parties owing under or in
respect of the Loan Documents or Secured Hedge Agreements that are due and payable
to the Administrative Agent and the other Secured Parties on such date,
ratably based upon the respective aggregate amounts of all such Secured
Obligations owing to the Administrative Agent and the other Secured Parties on
such date; and

 

(vi)          sixth, the balance,
if any, to the person lawfully entitled thereto (including the applicable Loan
Party or its successors or assigns) or as a court of competent jurisdiction may
direct.

 

(d)           If the Administrative Agent
receives funds for application to the Obligations of the Loan Parties under or
in respect of the Loan Documents under circumstances for which the Loan
Documents do not specify the Loans to which, or the manner in which, such funds
are to be applied, the Administrative Agent may, but shall not be obligated to,
in the case of the Loans, for application to such principal repayment
installments thereof, as the Administrative Agent shall direct, and in other
cases, elect to, distribute such funds to each of the Lenders in accordance
with such Lender’s pro rata share of the aggregate principal amount of the
Loans outstanding at such time, in repayment or prepayment of such of the outstanding
Loans or other Obligations then owing to such Lender.

 

(e)           Subject to any contrary
provisions in the definition of “Interest Period,” if any payment under this
Agreement or any of the other Loan Documents is specified to be made on a day
which is not a Business Day, it shall be made on the next Business Day, and
such extension of time shall in such case be included in computing interest and
fees, if any, in connection with such payment; provided, however,
that, 

 

31

 

if such extension would cause payment of
interest on or principal of Eurodollar Loans to be made in the next following
calendar month, such payment shall be made on the next preceding Business Day.

 

(f)            Unless the Administrative
Agent shall have received notice from Duratek prior to the date on which any
payment is due to any Lender hereunder that Duratek will not make such payment
in full, the Administrative Agent may assume that Duratek has made such payment
in full to the Administrative Agent on such date and the Administrative Agent
may, in reliance upon such assumption, cause to be distributed to each such
Lender on such due date an amount equal to the amount then due such
Lender.  If and to the extent Duratek
shall not have so made such payment in full to the Administrative Agent, each
such Lender shall repay to the Administrative Agent forthwith on demand such
amount distributed to such Lender together with interest thereon, for each day
from the date such amount is distributed to such Lender until the date such
Lender repays such amount to the Administrative Agent, at the Federal Funds
Rate.

 

Section 2.11           Reimbursement.

 

(a)           Whenever any Lender shall
sustain or incur any losses or out-of-pocket expenses in connection with (i) failure
by Duratek to borrow any Eurodollar Loan after having given notice of its intention
to borrow in accordance with Section 2.2
hereof (whether by reason of Duratek’s election not to proceed or the
non-fulfillment of any of the conditions set forth in Article 3),  or (ii) payment of any Eurodollar Loan in whole or in part
pursuant to Section 2.2(a)(ii), 2.6, 2.8 or 10.2, acceleration of the maturity of the Loans pursuant to Section 8.2 or for any other reason, Duratek agrees to
pay to such Lender, upon demand, an amount sufficient to compensate such Lender
for all such losses and reasonable out-of-pocket expenses.  Such Lender’s good faith determination of the
amount of such losses or out-of-pocket expenses, as set forth in writing
pursuant to Section 2.11(b) hereof,
and accompanied by calculations in reasonable detail demonstrating
the basis for its demand, shall be presumptively correct, absent manifest error.

 

(b)           Losses subject to reimbursement
hereunder shall be (i) any loss incurred by any Lender in connection with
the re-employment of funds prepaid, repaid, not borrowed, or paid, as the case
may be, and the amount of such loss shall be the excess, if any, of (1) the
interest or other cost to such Lender of the deposit or other source of funding
used to make any such Eurodollar Loan (but specifically excluding any
Applicable Margin) for the remainder of its Interest Period, over (2) the
interest earned (or to be earned) by such Lender upon the re-lending or other
redeployment of the amount of such Eurodollar Loan for the remainder of its
putative Interest Period or (ii) any other expenses incurred by any Lender
or any participant of such Lender permitted hereunder in connection with the
re-employment of funds prepaid, repaid, not borrowed, or paid, as the case may
be.

 

For the avoidance of doubt, nothing in this Section 2.11 shall be construed to apply to Taxes that
are neither Covered Taxes nor Other Taxes.

 

Section 2.12           Pro Rata Treatment.

 

(a)           Loans.  Each Loan from the Lenders shall be made pro
rata on the basis of the respective Commitments of the Lenders as set forth on Schedule
4 hereof.

 

(b)           Payments.  Except as specifically provided in Section 2.2(e)(iv) or Article 10
hereof or elsewhere in this Agreement, each payment and prepayment
of principal of the Loans and each payment of interest on the Loans, shall be
made to the Lenders pro rata on the basis of their respective unpaid principal
amounts outstanding immediately prior to such payment or prepayment.  If any Lender shall obtain any payment
(whether involuntary, through the exercise of any right of set-off, or
otherwise) on account 

 

32

 

of any Loans made by it in excess of its
ratable share of such Loans, such Lender shall forthwith purchase from the
other Lenders such interests (whether by purchasing a participation or by
assignment) in the applicable Loans made by them 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, such purchase from each Lender shall be
rescinded and each such Lender shall repay to the purchasing Lender the
purchase price to the extent of such recovery; provided  further, however,
that, so long as the Obligations under the Loan Documents shall not have been
accelerated, any excess payment received by any Lender in respect of any Type
of Loans shall be shared on a pro rata basis only with other Lenders to which
Loans of such Type are owing.  Duratek
agrees that any Lender so purchasing a participation from another Lender pursuant
to this Section 2.12(b) may, to the
fullest extent permitted by law, exercise all its rights of payment (including
the right of set-off) with respect to such participation as fully as if such
Lender were the direct creditor of Duratek in the amount of such participation.

 

Section 2.13           Capital Adequacy.

 

If, after the Agreement Date, the adoption or
effectiveness of any Applicable Law regarding the capital adequacy of banks or
bank holding companies, or any change or effectiveness in Applicable Law
(whether adopted before or after the Agreement Date) or any change in the
interpretation or administration or effectiveness thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by such Lender with any directive issued
or adopted after the Agreement Date regarding capital adequacy (whether or not
having the force of law) of any such governmental authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on any Lender’s capital, as a consequence of its obligations hereunder with respect
to the Loans, to a level below that which it could have achieved but for such
adoption, change or compliance (taking into consideration such Lender’s
policies with respect to capital adequacy immediately before such adoption,
change or compliance and assuming that such Lender’s capital was fully utilized
prior to such adoption, change or compliance) by an amount reasonably deemed by
such Lender to be material, then such Lender shall promptly notify Duratek of
such adoption, compliance or change. 
Upon demand by such Lender, Duratek shall promptly pay to such Lender
such additional amounts as shall be sufficient to compensate such Lender for
such reduced return, together with interest on such amount from the fourth
(4th) day after the date of demand until payment in full thereof at the Default
Rate.  A certificate of such Lender
setting forth the amount to be paid to such Lender by Duratek as a result of
any event referred to in this paragraph and supporting calculations in reasonable
detail shall be conclusive, absent manifest error.  For the avoidance of doubt, this Section 2.13 shall not apply to Taxes.

 

Section 2.14           Taxes.

 

(a)           Subject to the exclusions
and limitations of this Section 2.14 and
subject to the Lenders’ compliance with Section 2.14(f),
any and all payments by any Loan Party hereunder or under the other Loan
Documents shall be made free and clear of and without deduction or withholding
for any and all present or future taxes, levies, imposts, deductions, charges
or withholdings (“Taxes”) imposed or assessed on or with respect to
payments made under this Agreement or the other Loan Documents by the United
States of America or any political subdivisions thereof or therein or any other
jurisdiction (including non-U.S. jurisdictions), and all liabilities with
respect hereto or thereto (but excluding any tax imposed on or measured by the
net income or profits of a Lender or franchise taxes imposed in lieu of net
income taxes on overall gross receipts, or any other similar taxes imposed, in
each case, as a result of such Lender being organized in, having its principal
office or applicable lending office in, engaging in a trade or business in, or
having a present or former connection with the jurisdiction imposing such Tax
(other than any such trade or business, or connection arising or deemed to
arise solely or primarily from any 

 

33

 

transactions contemplated by this Agreement)
(all such non-excluded taxes, levies, imposts, duties, fees, assessments or
other charges being referred to collectively as “Covered Taxes”).

 

If any Loan Party shall be required by law to
withhold or deduct any Covered Taxes from or in respect of any sum payable
hereunder or under any other Loan Document to any Lender, (i) the sum payable
shall be increased as may be necessary so that after making all required
deductions or withholdings on account of Covered Taxes (including deductions
applicable to additional sums payable under this Section 2.14(a))
such Lender receives an amount equal to the sum it would have received had no
such deductions or withholdings of Covered Taxes been made, (ii) the
applicable Loan Party shall make such deductions or withholdings, and (iii) the
applicable Loan Party shall pay the full amount of Covered Taxes deducted to
the relevant taxation authority or other authority in accordance with Applicable
Law.

 

(b)           Duratek agrees to pay any present
or future recordation, transfer, mortgage, stamp or documentary taxes or any
other excise or property taxes, charges or similar levies (including any interest
and penalties related thereto) imposed by the United States of America or any
political subdivision thereof or any other jurisdiction (including non U.S. jurisdictions)
that arise from the execution, delivery, registration of, performance under, or
enforcement of, this Agreement or any other Loan Document (hereinafter referred
to as “Other Taxes”).

 

(c)           Without duplication of its
obligation to pay increased amounts on account of Covered Taxes and Other Taxes
pursuant to Sections 2.14(a) and (b), respectively, Duratek shall indemnify each Lender for
the full amount of Covered Taxes and Other Taxes (including, without limitation,
any Covered Taxes or Other Taxes imposed by any jurisdiction on amounts payable
under this Section 2.14) paid by such
Lender and any penalties, interest and expenses arising therefrom or with respect
thereto, whether or not such Covered Taxes or Other Taxes were correctly or
legally asserted.  Payment by Duratek
pursuant to this indemnification shall be made within thirty (30) days from the
date such Lender (as the case may be) makes written demand therefor (submitted
through the Administrative Agent).  A
Lender’s failure to provide notice to Duratek shall not relieve Duratek of any
of its obligations under this Section 2.14.  Notwithstanding the foregoing, where notice
is not given within one hundred twenty (120) days after the Lender has actual
notice of the assertion of taxes and Duratek does not otherwise have notice of
such assertion, no indemnification shall be required for penalties, additions
to tax, expenses, and interest accruing on such Covered Taxes or Other Taxes
from the date one hundred twenty (120) days after the Lender has actual notice
of the assertion of such taxes until the date such notice was actually received
by Duratek.

 

(d)           Within thirty (30) days
after the date of any payment of Covered Taxes or Other Taxes by the any Loan
Party, such Loan Party shall furnish to the Administrative Agent, at its
address referred to in Section 11.1 hereof,
the original or a certified copy of a receipt evidencing payment thereof.  The applicable Loan Party shall compensate
each Lender to the extent that such Lender is required to pay any Covered
Taxes or Other Taxes (or applicable penalties, interest and expenses) as a
result of any failure by such Loan Party to so furnish such copy of such
receipt.

 

(e)           The agreements and
obligations of the Loan Parties contained in this Section 2.14
shall survive the indefeasible payment in full of the Obligations.

 

(f)            Notwithstanding any
provision to the contrary in this Agreement, to the extent that such Person is
at such time legally entitled to do so, on the date a Person becomes an Agent
or Lender hereunder and at such other times as reasonably requested by Duratek
or the Administrative Agent in writing, such Person must provide to Duratek and
the Administrative Agent two properly completed and duly executed originals of
each of the following, as applicable:  (i) Form W-8ECI
(in the case of a non-U.S. Person claiming exemption from withholding because
the income is effectively connected with a U.S. trade or business), (ii) Form W-8BEN
(in the case of a non-U.S. Person claiming exemption from, or reduction 

 

34

 

of, withholding tax under an income tax
treaty or under the portfolio interest exemption), (iii) with respect to
any interest in this Agreement in which a participation has been sold, a Form W-8IMY
along with accompanying Form W-8BEN (claiming exemption from withholding
under the portfolio interest exemption), (iv) any other applicable form,
certificate or document necessary to establish such non-U.S. Person’s
entitlement to exemption from United States federal withholding tax or reduced
rate with respect to all payments to be made to such non-U.S. Person under this
Agreement, or (v) Form W-9 (claiming exemption from backup withholding
tax), or any successor forms.  Each Agent
and Lender agrees that from time to time after the Original Agreement Date,
when a lapse in time or change in circumstances renders the previous
certification obsolete or inaccurate in any material respect, such Agent or
Lender will, to the extent that such Agent or Lender is at such time legally
entitled to do so, deliver to Duratek and the Administrative Agent two new
accurate and complete original signed copies of the applicable certification
form.  Notwithstanding anything to the
contrary in this Section 2.14, a Lender shall
not be entitled to payment on account of or indemnification for Covered Taxes
that are U.S. federal withholding Taxes that are imposed pursuant to a law in
effect at the time such Lender becomes a party to this Agreement, except, in
the case of an assignee to the extent that such Lender’s assignor (if any) was
entitled, at the time of assignment, to receive additional amounts from the
Loan Parties with respect to such Tax pursuant to Section 2.14(a) and
a Lender shall not be entitled to a payment on account of or indemnification
for such Covered Taxes to the extent such Taxes result from the failure of such
Lender to comply with the documentation requirements of this Section 2.14(f).

 

(g)           If the Administrative Agent
or any Lender determines, in its good faith sole discretion, that it has
received a refund of any Covered Taxes or Other Taxes as to which it has been
indemnified by a Loan Party or with respect to which the Loan Party has paid
additional amounts pursuant to this Section 2.14,
it shall pay over such refund to such Loan Party (but only to the extent of indemnity
payments made, or additional amounts paid, by such Loan Party under this Section 2.14 with respect to the Covered Taxes or Other
Taxes giving rise to such refund), net of all out-of-pocket expenses of such
Agent or such Lender and without interest (other than any interest paid by the
relevant governmental authority with respect to such refund); provided,
that the Loan Party, upon the request of such Agent or such Lender, agrees to
repay the amount paid over to such Loan Party to such Agent or such Lender in
the event such Agent or such Lender is required to repay such refund to such
governmental authority.  This paragraph
shall not be construed to require any Agent or any Lender to make available its
tax returns (or any other information relating to its Taxes which it deems
confidential) to the Loan Party or any other Person. Notwithstanding anything
to the contrary, in no event will any Lender be required to pay any amount to a
Loan Party the payment of which would place such Lender in a less favorable net
after-tax position than such Lender would have been in if the additional
amounts giving rise to such refund of any Covered Taxes or Other Taxes had
never been paid.

 

(h)           Each Lender agrees that,
upon the occurrence of any event giving rise to the operation of Section 2.14 (a), Section 2.14(c) or
Section 10.3 with respect to such
Lender, it will, if requested by EnergySolutions, use reasonable efforts
(subject to overall policy considerations of such Lender) to designate another
lending office for any Loans affected by such event with the object of avoiding
the consequences of such event; provided, that such designation is made
on terms that, in the good faith sole judgment of such Lender, cause such
Lender and its lending office(s) to suffer no economic, legal or
regulatory disadvantage, and provided  further that nothing in
this Section 2.14 shall affect or
postpone any of the obligations of the Loan Party or the rights of any Lender
pursuant to Section 2.14(a), Section 2.14(c) or Section 10.3.

Representations
and Warranties

 

Section 4.1             Representations and Warranties.

 

Each of EnergySolutions and Duratek hereby agrees,
represents and warrants in favor of the Administrative Agent and each Lender
that:

 

(a)           Organization; Ownership; Power; Qualification.  EnergySolutions is a limited liability
company, or, to the extent permitted by Section 7.4(b)(v),
a corporation, duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization. 
EnergySolutions has the limited liability company power, or corporate
power, as applicable, and authority to own its properties and to carry on its
business as now being and hereafter proposed to be conducted.  Each Subsidiary and Parent is a corporation,
limited liability company or a partnership (as the case may be) duly organized,
validly existing and in good standing under the laws of the state of its
incorporation, organization or formation (as the case may be), and has the necessary
power and authority to own its properties and to carry on its business as now
being and hereafter proposed to be conducted. 
EnergySolutions, Parent and each of their respective Subsidiaries are
duly qualified, in good standing and authorized to do business in each
jurisdiction (other than their respective jurisdictions of incorporation,
organization or formation) in which the character of their respective
properties or the nature of their respective businesses makes such qualification
or authorization prudent, except where the failure to be so qualified and in
good standing would not reasonably be expected to result in a Material Adverse
Change.

 

(b)           Authorization; Enforceability.  EnergySolutions has the power and has taken
all necessary action to authorize it to borrow hereunder, to execute, deliver
and perform this Agreement and each of the other Loan Documents to which it is
a party in accordance with their respective terms, and to consummate the
transactions contemplated hereby and thereby. 
This Agreement has been duly executed and delivered by EnergySolutions
and is, and each of the other Loan Documents to which EnergySolutions is party
is, a legal, valid and binding obligation of EnergySolutions enforceable
against EnergySolutions in accordance with its terms, subject, as to enforcement
of remedies, to the following qualifications: 
(i) an order of specific performance and an injunction are discretionary
remedies and, in particular, may not be available where damages are considered
an adequate remedy at law, (ii) enforcement may be limited by bankruptcy,
insolvency, liquidation, reorganization, reconstruction and other similar laws
affecting enforcement of creditors’ rights generally (insofar as any such law
relates to the bankruptcy, insolvency or similar event of EnergySolutions), and
(iii) enforcement may be subject to general principles of equity
(regardless of whether such enforcement is considered in a proceeding in equity
or at law) and may be limited by public policies which may affect the
enforcement of certain rights or remedies provided for in this Agreement or the
Security Documents.

 

(c)           Subsidiaries and Parent; Authorization; Enforceability.  EnergySolutions’ Subsidiaries, Parent’s
Subsidiaries and all Investments of EnergySolutions and its direct and indirect
ownership thereof are set forth as of the Agreement Date on Schedule 1,
and except as set forth on Schedule 1 attached hereto, EnergySolutions
and Duratek have the unrestricted right to vote the issued and outstanding
shares of their corporate Subsidiaries, and the right to vote their partnership
and membership interests in such partnership and limited liability company
Subsidiaries in accordance with the terms of the applicable
partnership agreement or operating agreement, shown thereon; such shares of
such corporate Subsidiaries have been duly authorized and issued 

 

39

 

and are fully paid and nonassessable. 
Each of EnergySolutions, Parent and their respective Subsidiaries has
the necessary power and authority, and has taken all necessary action to
authorize it, to execute, deliver and perform each of the Loan Documents to
which it is a party in accordance with their respective terms and to consummate
the transactions contemplated by this Agreement and by such Loan
Documents.  Each of the Loan Documents to
which a Loan Party is party is a legal, valid and binding obligation of such Person,
enforceable against such Person in accordance with its terms, subject, as to

of ERISA or Section 4975 of the Code) which would reasonably be expected
to subject Parent or any of its Subsidiaries to a tax or penalty in any amount

of the Code or an obligation to indemnify any other person for such tax or
penalty, except as could not reasonably be expected to result in a Material

fees and expenses of one outside counsel to all Indemnitees with such local
counsel as may be necessary), experts’, agents’ and consultants’ fees and expenses
(as such fees and expenses are incurred) and demands by any party, including
the costs in connection with any investigation, litigation or proceeding or
preparation of a defense in connection therewith, whether or not Duratek,
EnergySolutions, Parent or any of their respective Subsidiaries, or the Person
seeking indemnification is the prevailing party, whether or not such investigation,
litigation or proceeding is brought by any Loan Party, its members, managers,
directors, shareholders or creditors or an Indemnitee or any other Person, and
whether or not any Indemnitee is otherwise a party thereto, (a) resulting
from any breach or alleged breach by Duratek, EnergySolutions,
Parent or any of their respective Subsidiaries of any representation,
warranty or covenant made hereunder or under any other Loan Document; (b) arising
out of or in connection with (i) any Commitment, any Loans, any Letter of
Credit or otherwise under this Agreement or any other Loan Document (including

Credit or otherwise under this Agreement or any other Loan Document, (iv) the

(b) or (c),  unless the Person seeking indemnification
hereunder is determined in such case to have acted with gross negligence or
willful misconduct or in breach of the Loan Documents, in any case by a final,
non-appealable judicial order.  The
obligations of Duratek, EnergySolutions, Parent and their respective Subsidiaries
under this Section 5.11 are in addition

any warranties or similar obligations of Duratek, EnergySolutions, Parent or

nothing in this Section 5.11 shall be
construed so as to apply to the indemnification of Taxes that are neither
Covered Taxes nor Other Taxes.

 

Section 5.12           Interest Rate Hedging.

 

At the end of each fiscal quarter, EnergySolutions
shall maintain in effect one or more Hedge Agreements in such aggregate
notional amount as necessary so that, with respect to no less than thirty-three
percent (33%) of the then outstanding aggregate principal balance of the Loans
and the EnergySolutions Term Loans, EnergySolutions’ obligations to make
floating rate interest payments thereunder will be hedged with
fixed rate payments to be paid under such Hedge Agreements.

 

Such Hedge Agreements shall provide interest rate
protection on terms (including, without limitation, consideration of the
creditworthiness of the other party to the proposed Hedge Agreement) reasonably
acceptable to (and with parties reasonably acceptable to) the Administrative
Agent for an average period of the lesser of (a) two (2) years from
the date of such Hedge Agreement or Hedge Agreements and (b) the period
remaining from the date thereof until the Maturity Date.  All Secured Obligations of EnergySolutions to
any of the Lenders pursuant to any Secured Hedge Agreement shall rank pari
passu with all other Secured Obligations. 
Any prepayment, acceleration, reduction, increase or any other change in
the terms of the Loans hereunder will not alter the notional amount of any such
Secured Hedge Agreement or otherwise affect EnergySolutions’ obligation to
continue making payments under any such Secured Hedge Agreement, which will
remain in full force and effect notwithstanding any such prepayment,
acceleration, reduction, increase or change, subject to the terms of such Secured
Hedge Agreement.

 

Section 5.13           Covenants Regarding Formation of Subsidiaries and
the Making of Acquisitions.

51

 

each will, and will cause
their respective Subsidiaries, as appropriate, to, (i) in the case of the

attached hereto, together with appropriate UCC-1 financing statements, as well
as an executed Subsidiary Guaranty for such new Subsidiary (other than any

Parent or any of their respective Subsidiaries or the formation of any new
Subsidiary, pledge to the Collateral Agent all of the capital stock, limited
partnership interests, general partnership interests, or other securities or
other equity or ownership interests of such Subsidiary or Person which is
acquired or formed, beneficially owned by EnergySolutions, Parent or any of
their respective Subsidiaries, as the case may be, as additional Collateral for
the Secured Obligations to be held by the Collateral Agent in accordance with
the terms of EnergySolutions’ Pledge Agreement, Parent Pledge Agreement,
Subsidiary Pledge Agreement or a new Subsidiary Pledge Agreement (it being understood
that (i) no Non-U.S. Subsidiary or Special Purpose Subsidiary shall be
required to execute any such Subsidiary Pledge Agreement and (ii) no Loan
Party shall be required to pledge any equity or ownership interest in a newly
acquired Subsidiary if (A) such pledge is prohibited by the terms of such
Subsidiary’s organizational documents or (B) such Subsidiary as a Special
Purpose Subsidiary) in substantially the form of Exhibit A attached
hereto, and execute and deliver to the Collateral Agent all such documentation
for such pledge as, in the reasonable opinion of the Collateral Agent, is
appropriate; provided that (A) in the case of any
Acquisition by EnergySolutions, Parent or any of their respective Subsidiaries
or the formation of any new Subsidiary that is a “first tier” Non-U.S.
Subsidiary, not more than 65% of the capital stock, limited partnership
interests, general partnership interests, or other securities or other equity
or ownership interests of any “first-tier” Non-U.S. Subsidiary or Person which
is acquired or formed, beneficially owned by EnergySolutions, Parent or any of
their respective Subsidiaries, as the case may be, shall be pledged to the
Collateral Agent as additional Collateral for the Secured Obligations to be
held by the Collateral Agent in accordance with the terms of EnergySolutions’
Pledge Agreement, Parent Pledge Agreement, Subsidiary Pledge Agreement or
a new Subsidiary Pledge Agreement; and (B) the requirement that any new
Subsidiary of any of EnergySolutions, Parent or any of their respective Subsidiaries
execute a Subsidiary Guaranty and a Subsidiary Security Agreement shall not
apply to a new non-wholly owned Subsidiary if, but only for so long as, (x) such
Subsidiary has total assets of less than $5,000,000 individually and (y) the
total assets of such Subsidiary, together with the total assets of all domestic
Subsidiaries that do not Guarantee the Secured Obligations, are less than
$10,000,000 in the aggregate; and (iii) in any case, provide all other
documentation, including one or more opinions of counsel reasonably
satisfactory to the Collateral Agent, which in the reasonable opinion of the
Collateral Agent is appropriate with respect to such Acquisition, Real Property
Acquisition or the formation of such Subsidiary.  Investments made by EnergySolutions, Parent
or any of their respective Subsidiaries after the Agreement Date shall also be
treated as additional Collateral and shall be subject to the provisions of the
appropriate Security Documents.  Any
document, agreement or instrument executed or issued pursuant to this Section 5.13 shall be a “Loan Document” for purposes of

Notwithstanding the foregoing, at all times
after the EnergySolutions Payoff, for the purpose of calculating the Leverage
Ratio pursuant to Section 7.7(a),
the First Lien Leverage Ratio pursuant to Section 7.7(b) and
the Interest Coverage Ratio pursuant to this Section 7.7(c),
Operating Cash Flow shall exclude (x) the net income of Duratek and its Subsidiaries
on a consolidated basis determined in accordance with GAAP and (y) any
items that would be added to the net income of Duratek and its Subsidiaries
in the calculation of the operating cash flow of Duratek and its Subsidiaries
(calculated in the same manner, and with the same adjustments, as “Operating
Cash Flow” of EnergySolutions and its Subsidiaries); provided that “Duratek and
its Subsidiaries” shall not include EnergySolutions and its Subsidiaries if
EnergySolutions is a Subsidiary of Duratek.

 

(d)           Maximum Capital Expenditures.  Permit the aggregate Capital Expenditures of
EnergySolutions and its respective Subsidiaries on a consolidated basis to be

However, to the extent the
aggregate Capital Expenditures of EnergySolutions and its respective Subsidiaries
on a consolidated basis in any one fiscal year (ending on or after December 31,
2005) are less than the maximum amount permitted pursuant to this Section 7.7(c), then EnergySolutions and its Subsidiaries
on a consolidated basis may expend an additional amount on Capital Expenditures
in a subsequent fiscal year equal to the dollar amount of the lesser of the
shortfall from such fiscal year and 50% of the amount permitted for Capital
Expenditures in the prior fiscal year; however, in no circumstance may any shortfall be carried
forward from more than one fiscal year at any time.

Collateral Agent; or

in this Agreement or in the other Loan Documents to the contrary
notwithstanding.

 

(c)           Upon acceleration of the

Section 7.7(a) or (b) (each, a “Financial
Condition Covenant”), until the expiration of the 20th day subsequent to
the date the certificate calculating such Financial Condition Covenant is
required to be delivered pursuant to Section 6.3, Parent shall have
the right to issue equity interests to the Equity Sponsors for cash, and, in
each case, to contribute any such cash to the capital of EnergySolutions
(collectively, the “Cure Right”), and upon the receipt by EnergySolutions
of such cash (the “Cure Amount”) pursuant to the exercise by Parent of
such Cure Right such Financial Condition Covenant shall be recalculated giving
effect to the following pro forma adjustments:

 

72

 

(i)      Operating Cash Flow shall be
increased, solely for the purpose of measuring the Financial Condition
Covenants and not for any other purpose under this Agreement, by an amount
equal to the Cure Amount; and

 

(ii)     If, after giving effect to
the foregoing recalculations, Parent shall then be in compliance with the
requirements of all Financial Condition Covenants, Parent shall be deemed to
have satisfied the requirements of the Financial Condition Covenants as of the
relevant date of determination with the same effect as though there had been no
failure to comply therewith at such date, and the applicable breach or default
of the Financial Condition Covenants which had occurred shall be deemed cured
for all purposes of this Agreement.

 

(b)                   Limitations on
Exercise of Cure Right, etc.  Notwithstanding anything herein to the contrary,
(a) in no event shall Parent be entitled to exercise the Cure Right in
more than two consecutive fiscal quarters and (b) each Cure Amount shall
not exceed the amount required to cure the applicable failure to comply with a
Financial Condition Covenant.  To the
extent a fiscal quarter ended for which the Financial Condition Covenants are
initially recalculated as a result of a Cure Right is included in the calculation
of a Financial Condition Covenant in a subsequent fiscal period, the Cure
Amount shall be included in the amount of Operating Cash Flow for such initial
fiscal period.

applicable, to take such actions as agents on its behalf and to exercise such
powers hereunder, under the Security Documents as are delegated by the terms
hereof and thereof, together with such powers as are reasonably incidental
thereto.  Notwithstanding anything in the
Loan Documents to the contrary, neither the Administrative Agent, the
Collateral Agent nor any of their respective directors, officers, employees or
agents shall be liable for any action taken or omitted to be taken by it or
them hereunder or in connection herewith, except for its or their own gross
negligence or willful misconduct.

 

Section 9.2             Interest Holders.

 

The Administrative Agent may treat each Lender, or
the Person designated in the last notice filed with the Administrative Agent,
whether under Section 11.1, Section 11.5 or otherwise hereunder, as the holder of
all of the interests of such Lender in its Loans and Commitments until written
notice of transfer, signed by such Lender (or the Person designated in the last
notice filed with the Administrative Agent) and by the Person designated in
such written notice of transfer, in form and substance satisfactory to the
Administrative Agent, shall have been filed with the Administrative Agent.

 

Section 9.3             Consultation with Counsel.

 

The Administrative Agent and the Collateral Agent
may consult with legal counsel selected by it with due care (which may
include counsel to Duratek) and shall not be liable for any action taken or suffered
by it in good faith in consultation with the Majority Lenders and in reasonable
reliance on such consultations.

 

73

 

Section 9.4             Documents.

 

The Administrative Agent and the Collateral
Agent shall be under no duty to examine, inquire into or pass upon the
validity, effectiveness or genuineness of this Agreement, any Note, any other
Loan Document or any other instrument, document or communication furnished
pursuant hereto or in connection herewith, and the Administrative Agent and the
Collateral Agent shall be entitled to assume (absent knowledge to the contrary)
that they are valid, effective and genuine, have been signed or sent by the
proper parties and are what they purport to be.

 

Section 9.5             CNAI and Affiliates.

 

With respect to its Commitments, the Loans
made by it and the Notes issued to it, if any, CNAI shall have the same rights
and powers under the Loan Documents as any other Lender and may exercise the
same as though it were not an Agent; and the term “Lender” or “Lenders” shall,
unless otherwise expressly indicated, include CNAI in its individual
capacity.  CNAI and its affiliates may
accept deposits from, lend money to, act as trustee under indentures of, accept
investment banking engagements from and generally engage in any kind of
business with, any Loan Party, any of its Subsidiaries and any Person that may
do business with or own securities of any Loan Party or any such Subsidiary,
all as if CNAI was not an Agent and without any duty to account therefor to the
Lenders.  No Agent shall have any duty to
disclose any information obtained or received by it or any of its Affiliates
relating to any Loan Party or any of its Subsidiaries to the extent such
information was obtained or received in any capacity other than as such Agent.

 

Section 9.6             Responsibility of the Administrative Agent and the
Collateral Agent.

 

The duties and obligations of the
Administrative Agent and the Collateral Agent under this Agreement and the
Security Documents are only those expressly set forth in this Agreement and the
Security Documents.  The term “Agent” is
used merely for convenience of reference, and the Administrative Agent and the
Collateral Agent shall not, either as a result of the use of such term or for
any other reason, have any duties or responsibilities except those expressly
set forth herein or in the other Loan Documents, or any fiduciary relationship
with any Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or otherwise exist
against the Administrative Agent or the Collateral Agent.  Each of the Administrative Agent and the
Collateral Agent shall be entitled to assume that no Default has occurred and
is continuing unless it has actual knowledge, or has been notified by Duratek,
of such fact or has been notified by a Lender in writing that such Lender considers
that a Default has occurred and is continuing, and such Lender shall specify in
detail the nature thereof in writing. 
Each of the Administrative Agent and the Collateral Agent shall not be
liable hereunder for any action taken or omitted to be taken except for its own
gross negligence or willful misconduct. 
The Administrative Agent shall provide promptly each Lender with copies
of such documents received from Duratek in connection with this Agreement as
such Lender may reasonably request.

 

Section 9.7             Collateral and Guaranty Matters.

 

(a)           The Collateral Agent, as collateral
agent hereunder and under the Security Documents, is hereby authorized to act
on behalf of the Secured Parties, in its own capacity and through other agents
and sub-agents appointed by it with due care, under the Security
Documents.  In connection with its role
as secured party with respect to the Collateral hereunder, the Collateral Agent shall act as
collateral agent, for itself and for the ratable benefit of the Secured
Parties, and such role as Collateral Agent shall be disclosed on all
appropriate accounts, certificates, filings, mortgages and other Collateral documentation.

 

74

 

(b)           The Lenders irrevocably authorize the
Collateral Agent, at its option and in its discretion, and the Collateral Agent
may, without further written consent or authorization from Lenders (subject to Section 11.12 hereof), and agrees with and for the
benefit of Duratek that it shall execute any documents or instruments and take
any further actions, in each case at the sole cost and expense of Duratek, necessary:

 

(i)      to
release any Lien on any property granted to or held by the Collateral Agent
under any Loan Document (A) upon termination of the Commitments and
payment in full of all Secured Obligations (other than contingent
indemnification obligations), (B) that is sold or transferred or to be
sold or transferred as part of or in connection with any sale, or transferred
in any liquidation or merger, in each case, permitted hereunder or under any
other Loan Document, or (C) subject to Section 11.12,
if approved, authorized or ratified in writing by the Majority Lenders;
or

 

(ii)     to
release any Guarantor (other than Parent) from its obligations under the Guaranty
if such Person ceases to be a Subsidiary as a result of a transaction permitted
hereunder.

 

Upon request by the
Administrative Agent at any time, the Majority Lenders will confirm in writing
the Administrative Agent’s or the Collateral Agent’s authority to release or
subordinate its interest in particular types or items of property, or to
release any Guarantor from its obligations under the Guaranty pursuant to this Section 9.7.

 

Section 9.8             Action by the Administrative Agent and the Collateral
Agent.

 

(a)           Each of the Administrative Agent and
the Collateral Agent shall be entitled to use its discretion with respect to
exercising or refraining from exercising any rights which may be vested in it
by, and with respect to taking or refraining from taking any action or actions
which it may be able to take under or in respect of, this Agreement, unless the
Administrative Agent or the Collateral Agent, as applicable, shall have been
instructed by the Majority Lenders to exercise or refrain from exercising such
rights or to take or refrain from taking such action.  Neither the Administrative Agent nor the
Collateral Agent shall incur any liability under or in respect of this
Agreement with respect to anything which it may do or refrain from doing in the
reasonable exercise of its judgment or which may seem to it to be necessary or
desirable in the circumstances for the protection of the interests of the
Lenders, except for its gross negligence or willful misconduct as determined by
a final, non-appealable order of a court having jurisdiction over the subject
matter.

 

(b)           In any event, neither the Collateral
Agent nor the Administrative Agent shall be liable to the Lenders or to any
Lender in acting or refraining from acting under this Agreement or any other
Loan Document in accordance with the instructions of the Majority Lenders or of
all the Lenders, where expressly required by this Agreement, and any action
taken or failure to act pursuant to such instructions shall be binding on all
Lenders.

 

Section 9.9             Notice of Default or Event of Default.

 

In the event that the Administrative Agent or
any Lender shall acquire actual knowledge, or shall have been notified, of any Default (other than through a notice by one
party hereto to all other parties), the Administrative Agent or such Lender
shall promptly notify the Administrative Agent, and the Administrative Agent
shall take such action and assert such rights under this Agreement as the Majority
Lenders or of all the Lenders, where expressly required by this Agreement,
shall request in writing, and the Administrative Agent shall not be subject to
any liability by reason of its acting pursuant to any such request.  If the Majority Lenders shall fail to request
the Administrative Agent to take action or to assert rights under 

 

75

 

this Agreement in respect of
any Default within ten (10) days after their receipt of the notice of any
Default from the Administrative Agent or any Lender, or shall request
inconsistent action with respect to such Default, the Administrative Agent may,
but shall not be required to, take such action and assert such rights as it
deems in its discretion to be advisable for the protection of the Lenders.

 

Section 9.10           Responsibility Disclaimed.

 

Each of the Administrative Agent and the
Collateral Agent shall not be under any liability or responsibility whatsoever
as agent:

 

(a)           to Duratek or any other Person as a consequence of any
failure or delay in performance by or any breach by any Lender or Lenders of
any of its or their obligations under this Agreement;

 

(b)           to any Lender or Lenders as a consequence of any failure
or delay in performance by, or any breach by, (i) Duratek of any of its
obligations under this Agreement or any Notes or any other Loan Document, or (ii) any
Subsidiary or any other obligor under any other Loan Document;

 

(c)           to any Lender or Lenders, for any statements,
representations or warranties in this Agreement, or any other document
contemplated by this Agreement or any other Loan Document, or any information
provided pursuant to this Agreement, any other Loan Document or any other
document contemplated by this Agreement, or for the validity, effectiveness,
enforceability or sufficiency of this Agreement, any Notes, any other Loan
Document or any other document contemplated by this Agreement;

 

(d)           to any Lender for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of, or the perfection or
priority of any lien or security interest created or purported to be created
under or in connection with, any Loan Document or any other instrument or
document furnished pursuant thereto; or

 

(e)           Under or in respect of any Loan Document by acting upon
any notice, consent, certificate or other instrument or writing (which may be
by telegram, telecopy or telex) believed by it to be genuine and signed or sent
by the proper party or parties.

 

Section 9.11           Indemnification.

 

(a)           Each Lender severally agrees to
indemnify each Agent (to the extent not promptly reimbursed by Duratek) from
and against such Lender’s ratable share (determined as provided below) of any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever that may be imposed on, incurred by, or asserted against such Agent
in any way relating to or arising out of the Loan Documents or any action taken or omitted by such Agent
under the Loan Documents (collectively, the “Indemnified Costs”); provided,
however, that no Lender shall
be liable for any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
from such Agent’s gross negligence or willful misconduct as found in a final,
non-appealable judgment by a court of competent jurisdiction.  Without limitation of the foregoing, each Lender
agrees to reimburse each Agent promptly
upon demand for its ratable share of any costs and expenses (including, without
limitation, fees and expenses of counsel) payable by Duratek under Section 11.2, to the extent that such Agent is not
promptly reimbursed for such costs and expenses by Duratek.  In the case of any investigation, litigation
or proceeding giving rise 

 

76

 

to any Indemnified Costs, this Section 9.11 applies whether any such investigation,
litigation or proceeding is brought by any Lender or any other Person.

 

(b)           [Reserved].

 

(c)           For purposes of this Section 9.11, the Lenders’ respective ratable shares of
any amount shall be determined, with respect to any time deemed appropriate by
such Agent, according to the aggregate principal amount of the Loans
outstanding at such time and owing to the respective Lenders.  The failure of any Lender to reimburse any
Agent, as the case may be, promptly upon demand for its ratable share of any
amount required to be paid by the Lenders to such Agent, as the case may be, as
provided herein shall not relieve any other Lender of its obligation hereunder
to reimburse such Agent for its ratable share of such amount, but no Lender
shall be responsible for the failure of any other Lender to reimburse such
Agent for such other Lender’s ratable share of such amount.  Without prejudice to the survival of any
other agreement of any Lender hereunder, the agreement and obligations of each
Lender contained in this Section 9.11 shall
survive the payment
in full of principal, interest and all other amounts payable hereunder and
under the other Loan Documents.

 

Section 9.12           Credit Decision.

 

Each Lender represents and warrants to each
other Lender, to each Agent and to the Administrative Agent that:

 

(a)           in making its decision to enter into this Agreement and to
make its Loans it has independently taken whatever steps it considers necessary
to evaluate the financial condition and affairs of EnergySolutions and its
respective Subsidiaries and that it has made an independent credit judgment,
and that it has not relied upon the Administrative Agent, any Agent or any
other Lender, or information provided by the Administrative Agent (other than
information provided to the Administrative Agent by EnergySolutions and
forwarded by the Administrative Agent to the Lenders); and

 

(b)           so long as any portion of the Obligations remains
outstanding, it will continue to make its own independent evaluation of the
financial condition and affairs of EnergySolutions and its respective
Subsidiaries.

 

Section 9.13           Successor Agents.

 

(a)           Resignation of Administrative
Agent.  The Administrative Agent may
resign at any time by giving written notice five days prior to the effective
date of such resignation to the Lenders and Duratek.  Upon any such resignation, the Majority
Lenders shall have the right, in consultation with Duratek, to appoint a
successor Administrative Agent; provided
that, at the time of the resignation of the Administrative Agent, no successor
Administrative Agent has been appointed by the Majority Lenders, the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative
Agent, which shall be any Lender or a commercial bank organized under the laws
of the United States of America or any political subdivision thereof which has
combined capital and reserves in excess of $250,000,000.  Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested
with all the rights, powers, privileges, duties and obligations of the retiring
Administrative Agent and the retiring Administrative Agent shall be discharged
from its duties and obligations under the Loan Documents.  After any retiring Administrative Agent’s
resignation hereunder as Administrative Agent, the provisions of this Article shall
continue in effect for its benefit in respect of any actions taken or omitted
to be taken by it while it was acting as the Administrative Agent.

 

77

 

(b)           Resignation of Collateral Agent.  The Collateral Agent may resign at any time
by giving written notice of such resignation to the Lenders and Duratek.  Upon any such resignation, the Majority
Lenders shall have the right, in consultation with Duratek, to appoint a
successor Collateral Agent; provided
that if, at the time of the resignation of the Administrative Agent, no
successor Collateral Agent has been appointed by the Majority Lenders, the
retiring Collateral Agent may, on behalf of the Lenders, appoint a successor
Collateral Agent and, after its resignation and prior to the appointment of any
successor Collateral Agent, the retiring Collateral Agent will act as a nominee
for perfection with respect to the applicable Collateral.  Upon the acceptance of any appointment as
Collateral Agent hereunder by a successor Collateral Agent, such successor Collateral
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges, duties and obligations of the retiring Collateral Agent and the
retiring Collateral Agent shall be discharged from its duties and obligations
under the Loan Documents.  After any
retiring Collateral Agent’s resignation hereunder as Collateral Agent, the
provisions of this Article shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting
as the Collateral Agent.

 

(c)           General.  If no successor agent shall have been
appointed and shall have accepted such appointment prior to the resignation of
the Administrative Agent or Collateral Agent, then the retiring Administrative
Agent or Collateral Agent, as applicable, shall thereupon be discharged from
its duties and obligations under the Loan Documents and (iii) the Majority
Lenders shall thereafter perform all duties of the retiring Administrative Agent or Collateral Agent, as
applicable, under the Loan Documents until such time, if any, as the Majority
Lenders appoint a successor Administrative Agent or Collateral Agent, as
applicable, as provided above.  After any
retiring agent’s resignation hereunder as Administrative Agent or Collateral
Agent shall have become effective, the provisions of this Article 9
shall inure to its benefit as to any actions taken or omitted to be
taken by it while it was Administrative Agent or Collateral Agent, as
applicable, under this Agreement.

 

Section 9.14           Delegation of Duties.

 

The Administrative Agent may execute any of
its duties under the Loan Documents by or through agents or attorneys selected
by it using reasonable care, and shall be entitled to advice of counsel concerning
all matters pertaining to such duties.

 

Section 9.15           Additional Agents.

 

None of the Lenders or other entities
identified on the facing page of, signature pages of or elsewhere in
this Agreement as a “syndication agent,” “documentation agent,” “sole bookrunner”
or “sole lead arranger” shall have any right, power, obligation, liability,
responsibility or duty under this Agreement or any other Loan Document other
than those applicable to all Lenders as such. 
Without limiting the foregoing, none of the Lenders so identified shall
have or be deemed to have any fiduciary relationship with any other
Lender.  Each Lender acknowledges that it
has not relied, and will not rely, on any of the Lenders or other entities so
identified in deciding to enter into this Agreement or any other Loan Document
or in taking or not taking action hereunder or thereunder.

 

Section 9.16           Administrative Agent May File Proofs of Claim.

 

(a)           In case of the pendency of any
receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement,
adjustment, composition or other judicial proceeding relative to any Loan
Party, the Administrative Agent or its designee (irrespective of whether the
principal of any Loan shall then be due and payable as herein expressed or by
declaration or otherwise and irrespective of whether the Administrative Agent
shall have made any demand on Duratek) shall be entitled and empowered, by intervention
in such proceeding or otherwise:

 

78

 

(i)      to
file and prove a claim for the whole amount of the principal and interest owing
and unpaid in respect of the Loans and all other Obligations that are owing and
unpaid and to file such other documents as may be necessary or advisable in
order to have the claims of the Lenders and the Administrative Agent (including
any claim for the reasonable compensation, expenses, disbursements and advances
of the Lenders and the Administrative Agent and their respective agents and
counsel and all other amounts due the Lenders and the Administrative Agent under
Sections 2.3 and 11.2)
allowed in such judicial proceeding; and

 

(ii)     to
collect and receive any monies or other property payable or deliverable on any
such claims and to distribute the same;

 

and any custodian, receiver,
assignee, trustee, liquidator, sequestrator or other similar official in any
such judicial proceeding is hereby authorized by each Lender to make such
payments to the Administrative Agent and, in the event that the Administrative
Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent
any amount due for the reasonable compensation, expenses, disbursements and
advances of the Administrative Agent and its agents and counsel, and any other
amounts due the Administrative Agent under Sections 2.5
and 11.2.

 

(b)           Nothing contained herein shall be
deemed to authorize the Administrative Agent to authorize or consent to or
accept or adopt on behalf of any Lender any plan of reorganization,
arrangement, adjustment or composition affecting the Obligations or the rights
of any Lender or to authorize the Administrative Agent to vote in respect of
the claim of any Lender in any such proceeding.

 

Section 9.17           Security Documents.

 

Notwithstanding anything herein to the
contrary, each Lender also acknowledges that CNAI, Collateral Agent hereunder,
is also acting as Collateral Agent under the EnergySolutions Credit Agreement,
and in such dual capacities has entered into the Security Documents on behalf
of both the Secured Parties hereunder as well as the secured parties under the EnergySolutions Credit Agreement,
each Secured Party hereby waiving any actual or potential conflict or breach of
duty created or existing as the result of such dual capacities and
acknowledging that it has read the terms and conditions of the Security
Documents and has accepted the same without reliance on any of the Agents.

 

ARTICLE 10.

Change in Circumstances

Affecting Fixed Rate Loans

 

Section 10.1           Eurodollar Basis Determination Inadequate or Unfair.

 

If, with respect to any proposed Eurodollar
Loan for any Interest Period, the Administrative Agent determines after consultation
with the Lenders that deposits in Dollars (in the applicable amount) are not
being offered to each of the Lenders in the relevant market for such Interest
Period, the Administrative Agent shall forthwith give notice thereof to Duratek
and the Lenders, whereupon until the Administrative Agent notifies Duratek that
the circumstances giving rise to such situation no longer exist, the
obligations of any affected Lender to make or continue Eurodollar Loans shall
be suspended.

 

Section 10.2           Illegality.

 

If after the Agreement Date the adoption of
any Applicable Law, or any change in any Applicable Law (whether adopted before
or after the Agreement Date), or any change in interpretation or administration

 

79

 

thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender with any
directive (whether or not having the force of law) of any such authority,
central bank or comparable agency, shall make it unlawful or impossible, or any
such governmental authority, central bank or comparable agency shall assert
that it is unlawful, for any Lender to make, maintain or fund Eurodollar Loans,
such Lender shall so notify the Administrative Agent, and the Administrative
Agent shall forthwith give notice thereof to the other Lenders and
Duratek.  Before giving any notice to the
Administrative Agent pursuant to this Section 10.2,
such Lender shall designate a different lending office if such designation will
avoid the need for giving such notice and will not, in the sole judgment of
such Lender, be otherwise materially disadvantageous to such Lender.  Upon receipt of such notice, notwithstanding
anything contained in Article 2
hereof, (a) the obligation of the Lenders to make or continue Eurodollar
Loans shall be suspended until the Administrative Agent shall notify Duratek
and the Lenders that the circumstances causing such suspension no longer exist
and (b) unless Duratek, within three (3) Business Days thereafter,
converts all Eurodollar Loans into Base Rate Loans in accordance with the terms
of this Agreement, Duratek shall repay in full the then outstanding principal
amount of each affected Eurodollar Loan of such Lender, together with accrued
interest thereon and any reimbursement required under Section 2.11
hereof, on either (i) the last day of the then current Interest
Period applicable to such affected Eurodollar Loans if such Lender may lawfully
continue to maintain and fund such Eurodollar Loans to such day or (ii) immediately
if such Lender may
not lawfully continue to fund and maintain such affected Eurodollar Loans to
such day.  Concurrently with repaying
each affected Eurodollar Loan of such Lender, notwithstanding anything contained
in Article 2 or Article 3
hereof, Duratek may borrow a Base Rate Loan from such Lender, and such Lender
shall make such Base Rate Loan, if so requested, in an amount such that the
outstanding principal amount held by such Lender shall equal the outstanding
principal amount immediately prior to such repayment.

 

Section 10.3                                Increased
Costs.

 

(a)                                  If
after the Agreement Date the adoption or effectiveness of any Applicable Law or
any change or effectiveness in any Applicable Law (whether adopted before or
after the Agreement Date) or any interpretation or change in interpretation or
administration or effectiveness thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof or compliance by any Lender with any directive (whether or not having
the force of law) of any such authority, central bank or comparable agency:

 

(i)            shall
subject any Lender to any tax, duty or other charge with respect to its obligation
to make or continue Eurodollar Loans, or its Eurodollar Loans, or shall change
the basis of taxation of payments to any Lender of the principal of or interest
on its Eurodollar Loans or in respect of any other amounts due under this
Agreement, in respect of its Eurodollar Loans or its obligation to make or
continue Eurodollar Loans (except for changes in the rate or method of calculation
of tax on the overall net income of such Lender); or

 

(ii)           shall
impose, modify or deem applicable any reserve (including, without limitation,
any imposed by the Board of Governors of the Federal Reserve System, but
excluding any included in an applicable Eurodollar Reserve Percentage), special
deposit, capital adequacy, assessment or other requirement or condition against
assets of, deposits with or for the account of, or commitments or credit
extended by, any Lender or shall impose on any Lender or the London interbank
borrowing market or the New York certificate of deposit market any other
condition affecting its obligation to make or continue Eurodollar Loans or its
Eurodollar Loans;

 

and the result of any of the
foregoing is to increase the cost to such Lender of making or maintaining any
such Eurodollar Loans or to reduce the amount of any sum received or receivable
by such Lender under 

 

80

 

this Agreement with respect
thereto, then, within five (5) days after demand by such Lender, Duratek
agrees to pay to such Lender such additional amount or amounts as will compensate
such Lender for such increased costs (other than any increased costs resulting
from Taxes that are Covered Taxes or Other Taxes (which shall be governed
exclusively by Section 2.14) or are excluded
from the definition of “Covered Taxes” under Section 2.14(a)).  Each Lender will promptly notify Duratek and
the Administrative Agent of any event of which it has knowledge, occurring
after the Agreement Date, which will entitle such Lender to compensation
pursuant to this Section 10.3 and will
designate a different lending office if such designation will avoid the need
for, or reduce the amount of, such compensation and will not, in the sole
judgment of such Lender, be otherwise disadvantageous to such Lender.

 

(b)           Any Lender claiming compensation
under this Section 10.3 shall provide Duratek
with a written certificate setting forth the additional amount or amounts to be
paid to it hereunder and calculations therefor in reasonable detail.  Such certificate shall be presumptively correct, absent manifest
error.  In determining such amount, such
Lender may use any reasonable averaging and attribution methods.  If any Lender demands compensation under this
Section 10.3, Duratek may at any
time, upon at least five (5) Business Days’ prior notice to such Lender,
prepay in full the then outstanding affected Eurodollar Loans of such Lender,
together with accrued interest thereon to the date of prepayment, along with
any reimbursement required under Section 2.11 hereof.  Concurrently with prepaying such Eurodollar
Loans, notwithstanding anything contained in Article 2
or Article 3 hereof, Duratek may borrow
a Base Rate Loan from such Lender, and such Lender shall, if so requested, make
such Base Rate Loan in an amount such that the outstanding principal amount
held by such Lender shall equal the outstanding principal amount immediately
prior to such prepayment.

 

(c)           If any Lender requests compensation
under this Section 10.3,  then EnergySolutions may, at its sole expense
and effort, upon notice to such Lender and the Administrative Agent, require
such Lender to assign and delegate, without recourse (in accordance with and
subject to the restrictions contained in, and consents required by, Section 11.5), all of its interests, rights and
obligations under this Agreement and the related Loan Documents to an assignee
that shall assume such obligations (which assignee may be another Lender, if a
Lender accepts such assignment); provided that:  (i) EnergySolutions shall have paid to
the Administrative Agent the assignment fee specified in Section 11.5,
(ii) such Lender shall have received payment of an amount equal to the
outstanding principal of and premium (if any) on its Loans, accrued interest
thereon, accrued fees and all other amounts payable to it hereunder and under
the other Loan Documents (including any amounts Section 2.11,
treating such assignment as a voluntary prepayment) from the assignee (to the
extent of such outstanding principal and accrued interest and fees) or
EnergySolutions (in the case of all other amounts); (iii) such assignment
will result in a reduction in such compensation or payments thereafter; and (iv) such
assignment does not conflict with Applicable Law.  A Lender shall not be required to make any
such assignment or delegation if, prior thereto, as a result of a waiver by
such Lender or otherwise, the circumstances entitling EnergySolutions to require
such assignment and delegation cease to apply. 
Each Lender agrees that, if EnergySolutions elects to replace such
Lender in accordance with this Section, it shall promptly execute and deliver
to the Administrative Agent an Assignment and Assumption to evidence such sale
and purchase and shall deliver to the Administrative Agent any Note (if Notes
have been issued in respect of such Lender’s Loans) subject to such Assignment
and Assumption; provided
that the failure of any such non-consenting Lender to execute an Assignment and
Assumption shall not render such sale and purchase (and the corresponding
assignment) invalid and such assignment shall be recorded in the Register.

 

Section 10.4           Effect on Other Loans.

 

(a)           If notice has been given pursuant to Section 10.1, 10.2 or 10.3 suspending the obligation of any Lender to make or continue
Eurodollar Loans, or requiring Eurodollar Loans of any Lender to be 

 

81

 

repaid or prepaid, then, unless
and until such Lender notifies Duratek that the circumstances giving rise to
such repayment no longer apply, all Loans which would otherwise be made or continued
as Eurodollar Loans shall, at the option of Duratek, be made or continued instead
as Base Rate Loans.

 

(b)           If, with respect to any Eurodollar
Loan, Lenders owed at least 51% of the then aggregate unpaid principal amount
thereof notify the Administrative Agent that the Eurodollar Rate for any
Interest Period for such Loan will not adequately reflect the cost to such
Lenders of making, funding or maintaining their Eurodollar Loans for such
Interest Period, the Administrative Agent shall forthwith so notify Duratek and
the Lenders which have made such Loan, whereupon (i) such Eurodollar Loan
will automatically, on the last day of the then existing Interest Period
therefor, be continued as a Base Rate Loan and (ii) the obligation of the
Lenders which have made such Loan to make further or continue Eurodollar Loans
shall be suspended until the Administrative Agent shall notify Duratek that
such Lenders have determined that the circumstances causing such suspension no
longer exist.

Section 11.2           Costs and Expenses.

 

(a)           Duratek will promptly pay, or
reimburse, without duplication:

 

(i)      all
reasonable out-of-pocket expenses of the Administrative Agent or the
Collateral Agent in connection with the preparation, structuring, due
diligence, negotiation, execution, delivery, syndication and administration of
this Agreement and the other Loan Documents and the transactions related
hereto, contemplated hereunder and thereunder and the making of the initial
Loans hereunder (whether or not such Loans are made), including, but not
limited to, the reasonable fees and disbursements of Cahill Gordon &
Reindel LLP, special counsel for the Arranger;

 

83

 

(ii)     all
reasonable out-of-pocket expenses of the Administrative Agent or the
Collateral Agent in connection with the administration of the
transactions contemplated in this Agreement or the other Loan Documents, the
restructuring and “work out” of such transactions and the preparation, negotiation,
execution and delivery of any waiver, amendment or consent, whether or not such
waiver, amendment or consent shall become effective, by the Administrative
Agent and the Lenders relating to this Agreement or the other Loan Documents,
including, but not limited to, the reasonable fees and disbursements of any
experts, agents or consultants and of special counsel for the Administrative
Agent or the Collateral Agent (limited to one outside counsel to the
Administrative Agent and the Collateral Agent and such local counsel as may be
necessary for the Administrative Agent and the Collateral Agent), but excluding
any assignment fee pursuant to Section 11.5(b) hereof;
and

 

(iii)    all
out-of-pocket costs and expenses of the Administrative Agent or the
Collateral Agent and the Lenders in connection with the enforcement of
this Agreement or the other Loan Documents
and all out-of-pocket costs and expenses of collection if an Event of Default occurs
in the payment of the Loans or the other Obligations, whether in any action,
suit or litigation, or any bankruptcy, insolvency, liquidation, or other
similar proceeding affecting creditors’ rights generally, which in each case
shall include reasonable fees and out-of-pocket expenses of one respective
outside counsel and such local counsel as may be necessary for the
Administrative Agent, the Collateral Agent and the Lenders.

 

(b)           Duratek also agrees not to assert any
claim against any Agent, any Lender or any of their Affiliates, or any of their
respective officers, directors, employees, agents and advisors, on any theory
of liability, for special, indirect, consequential or punitive damages arising
out of or otherwise relating to the Commitments, the actual or proposed use of
the proceeds of  any Loan, the Loan Documents or
any of the transactions contemplated by the Loan Documents.

 

(c)           If any Loan Party fails to pay when
due any costs, expenses or other amounts payable by it under any Loan Document,
including, without limitation, fees and expenses of counsel and indemnities,
such amount may be paid on behalf of such Loan Party by the Administrative
Agent.

 

Section 11.3           Waivers.

 

The rights and remedies of the Administrative
Agent, the Collateral Agent and the Lenders under this Agreement and the other
Loan Documents shall be cumulative and not exclusive of any rights or remedies
which they would otherwise have.  No
failure or delay by the Administrative Agent, the Collateral Agent or the
Lenders, or any of them, in exercising any right shall operate as a waiver of
such right.  The Administrative Agent and
the Lenders expressly reserve the right to require strict compliance with the
terms of this Agreement in connection with any future funding of a request for
a Loan.  In the event the Lenders decide
to fund a Loan at a time when Duratek is not in strict compliance with the
terms of this Agreement, such decision by the Lenders shall not be deemed to
constitute an undertaking by the Lenders to fund any further Loans, or to
preclude the Lenders and the Administrative Agent from exercising any rights
available under the Loan Documents or at law or equity.  Any waiver or indulgence granted by the
Administrative Agent, the Lenders or the Majority Lenders shall not constitute
a modification of this Agreement, except to the extent expressly provided in
such waiver or indulgence, or constitute a course of dealing at variance with
the terms of this Agreement such as to require further notice of their intent
to require strict adherence to the terms of this Agreement in the future.

 

84

 

Section 11.4           Set-Off.

 

In addition to any rights now or hereafter
granted under Applicable Law and not by way of  limitation
of any such rights, upon the occurrence of an Event of Default and during the
continuation thereof, the Administrative Agent and the Lenders are hereby
authorized by Duratek at any time or from time to time, without notice to
Duratek or to any
other Person, any such notice being hereby expressly waived, to set off and to
appropriate and to apply any and all deposits (general or special, time or
demand, including, but not limited to, Indebtedness evidenced by certificates
of deposit, in each case whether matured or unmatured) and any other Indebtedness
at any time held or owing by any Lender or the Administrative Agent to or for
the credit or the account of Duratek or any of its Subsidiaries against and on
account of the Obligations irrespective of whether (a) any Lender or the
Administrative Agent shall have made any demand hereunder or (b) the
Administrative Agent shall have declared the principal of and interest on the
Loans and other amounts due hereunder to be due and payable as permitted by Section 8.2 and although such Obligations or any of
them shall be contingent or unmatured. 
Upon direction by the Administrative Agent with the consent of the
Majority Lenders, each Lender holding deposits of Duratek or any of its
Subsidiaries shall exercise its set-off rights as so directed.

 

Section 11.5           Binding Effect and Assignment.

 

(a)           This Agreement shall become effective
when it shall have been executed by Duratek and each Agent and the
Administrative Agent shall have been notified by each Lender hereto, and
Duratek shall have been notified by the Administrative Agent, that each such
Lender hereto has executed it and thereafter shall be binding upon and inure to
the benefit of Duratek, each Agent and each such Lender and their respective
successors and assigns, except that Duratek shall not have the right to assign
its rights hereunder or any interest herein without the prior written consent
of all of the Lenders.

 

(b)           Each Lender may enter freely into
participation agreements with respect to or otherwise grant participations in
its Loans to one or more banks or other lenders or financial institutions; provided,
however, that (i) such Lender’s obligations hereunder shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) the participant
shall not be entitled by the benefit of its participation to vote or otherwise
take action under this Agreement or any other Loan Document, except with
respect to the matters referred to in Section 11.12 hereof
relating to the matters in which affected Lenders are required to vote or all
Lenders are required to vote, (iv) such Lender shall deliver to the
Administrative Agent and Duratek (in such number of copies as shall be
reasonably requested by the recipient) duly signed and properly completed
copies of Internal Revenue Service Form W-8 IMY (or any successor thereto)
for each participant, and (v) Duratek shall continue to deal solely and
directly with such Lender in connection with such Lender’s rights and obligations
hereunder.  In addition, each Lender may
sell up to 100%, assign or create a security interest in all or any portion of
its rights hereunder and under the other Loan Documents to any other Person on
an assignment basis; provided that (A) (I) at any time
hereunder, such assignment is to an Affiliate of the assignor, an Approved
Fund, another Lender or any Conduit Lender, (II) prior to a date to be
separately agreed among Duratek and the Arranger (the “Syndication Date”),
such assignment is made by the Administrative Agent in connection with
syndication of any of the Loans, (III) prior to the Syndication Date, the
Administrative Agent has given its written consent to the proposed assignee of
a Lender hereunder or (IV) after the Syndication Date, Duratek (unless
there exists at the time of such assignment an Event of Default hereunder) and
the Administrative Agent have given their prior written consent to the proposed
assignee of a Lender hereunder, which consents shall not be unreasonably
delayed, conditioned or withheld, and (B) each such assignment shall be in
a principal amount of not less than the lesser of (I) the entire amount of
such Lender’s interest hereunder or (II) $1,000,000 (calculated on a
combined basis with such Lender’s contemporaneous assignment of its EnergySolutions
Term Loans and Term L/C Facility 

 

85

 

Deposits (as such terms are
defined in the EnergySolutions Credit Agreement) unless an assignment is from
one Lender to another or to an Approved Fund or an Affiliate of a Lender, in
which case there shall be no minimum assignment amount.  Each Lender who sells or assigns a portion of
its Loans pursuant hereto shall pay to the Administrative Agent an assignment
fee of $3,500 with
respect to each assignment (except that one such fee shall be payable in
connection with simultaneous assignments (i) to or by two or more Approved
Funds and (ii) of the EnergySolutions Term Loans), such fee to be paid to
the Administrative Agent not later than the effective date of the assignment of
the Loan relating thereto.  All assignments
by any of the Lenders of any interests hereunder shall be made pursuant to an
Assignment and Acceptance.  Each Lender
may provide any proposed participant or assignee with confidential information
provided to such Lender regarding EnergySolutions, Parent, Duratek and their
respective Subsidiaries on a confidential basis, and such participant or
assignee shall agree to maintain such confidentiality in accordance with the
provisions of Section 11.19 hereof.  Further, each permitted assignee or
participant with respect to any portion of the Loans shall be entitled to the
benefits, and subject to the burdens, of Sections 2.11, 2.13, 2.14 and Article 10 hereof and all other provisions hereof and
of the other Loan Documents as a “Lender” hereunder.  Each Participant shall be entitled to
the benefits of Sections 2.11, 2.13 and 2.14 and Article 10 (subject to the requirements of those
Sections) to the same extent as if it were a Lender, but no participant shall be entitled to a greater
payment under Section 2.14 than the applicable Lender would have been
entitled to receive with respect to the participation sold.  Upon the grant of a participation of its commitment
by a Lender pursuant to this Section 11.5(b),
such Lender (on behalf of Duratek) shall maintain a register analogous to the
Register described in Section 11.5(c) below.  Notwithstanding anything to the contrary set
forth herein, each assignment by a Lender of its Loans hereunder shall be made
concurrently with the ratable assignment of all or a portion of such Lender’s EnergySolutions Term Loans
and Term L/C Facility Deposits  and no
assignment of the Loans shall be made by any Lender hereunder unless such
Lender makes a simultaneous ratable assignment of all or a portion of its EnergySolutions
Loans; provided that immaterial deviations of the ratable assignment
provisions of this Section 11.5(b) shall
be permitted.  Before and after any assignment
of Term Loans by any Lender, the ratios of (i) such Lender’s Term Loans to
the aggregate principal amount of Term Loans outstanding, (ii) such Lender’s
Term L/C Facility Deposits and (iii) such Lender’s EnergySolutions Term
Loans to the aggregate principal amount of EnergySolutions Term Loans
outstanding, shall be identical; provided that immaterial deviations of
the ratable assignment provisions of this Section 11.5(b) shall
be permitted.

 

(c)           The Administrative Agent, acting for
this purpose as an agent of Duratek, shall maintain a copy of each Assignment
and Acceptance delivered to it and a register for the recordation of the names
and addresses of the Lenders and the Commitments of and the principal amount of
the Loans owing to each Lender pursuant to the terms hereof from time to time
(the “Register”).  The entries in
the Register shall be conclusive, absent manifest error, and Duratek, the
Administrative Agent and the Lenders shall treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for
all purposes of this Agreement, notwithstanding notice to the contrary.  The Register shall be available for
inspection at the offices of the Administrative Agent by Duratek or any Lender,
at any reasonable time during normal business hours and from time to time upon
reasonable prior notice.  Each Lender
agrees to provide the Administrative Agent and Duratek with written notice of
the assignment of all or part of its rights hereunder.  Upon the Administrative Agent’s receipt of a
duly completed Assignment and Acceptance executed by an assigning Lender and an
assignee Lender, the assignee’s completed administrative questionnaire (unless
the assignee is already a Lender), the fee referred to in Section 11.5(b) above
and any written consent to such assignment required thereby, the Administrative
Agent shall accept such Assignment and Acceptance and record the information
contained therein in the Register.  No
assignment shall be effected for purposes of this Agreement unless it has been
recorded in the Register as provided in this paragraph.

 

86

 

(d)           Notwithstanding anything to the
contrary contained in this Section 11.5,
any Lender that is a fund that invests in bank loans may (without the consent
of Duratek or the Administrative Agent) pledge all or a portion of its rights
in connection with this Agreement to the trustee or any holder of obligations
or agents therefor owed, or securities issued, by such fund as security for
such obligations or securities.  No
pledge described in the immediately preceding sentence shall release any such
Lender from its obligations hereunder.

 

(e)           [Reserved].

 

(f)            Except as specifically set forth in Section 11.5(b) hereof, nothing in this Agreement
or any Notes, express or implied, is intended to or shall confer on any Person
other than the respective parties hereto and thereto and their successors and
assignees permitted hereunder and thereunder any benefit or any legal or
equitable right, remedy or other claim under this Agreement or any Notes.

 

(g)           The provisions of this Section 11.5 shall not apply to any purchase of participations
among the Lenders pursuant to Section 2.12
hereof.

 

(h)           Notwithstanding anything to the
contrary contained herein, any Lender (a “Granting Lender”) may grant to
a special purpose funding vehicle identified as such in writing from time to
time by the Granting Lender to the Administrative Agent and Duratek (a “Conduit
Lender”) the option to provide all or any part of any Loan that such
Granting Lender would otherwise be obligated to make pursuant to this
Agreement; provided that (i) nothing herein shall constitute a
commitment by any Conduit Lender to fund any Loan, and (ii) if a Conduit
Lender elects not to exercise such option or otherwise fails to make all or any
part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant
to the terms hereof.  The making of a
Loan by a Conduit Lender hereunder shall utilize the applicable Commitment of
the Granting Lender to the same extent, and as if, such Loan were made by such
Granting Lender.  Each party hereto
hereby agrees that (i) no Conduit Lender shall be liable for any indemnity
or similar payment obligation under this Agreement for which a Lender would be
liable, (ii) no Conduit Lender shall be entitled to the benefits of Sections 2.13, 2.14 and 10.3 (or any other increased costs protection provision) to
any greater extent than the Granting Lender would have been entitled absent the
use of a Conduit Lender and (iii) the Granting Lender shall for all
purposes, including, without limitation, the approval of any amendment or
waiver of any provision of any Loan Document, remain the Lender of record
hereunder.  In furtherance of the
foregoing, each party hereto hereby agrees (which agreement shall survive the
termination of this Agreement) that, prior to the date that is one year and one
day after the payment in full of all outstanding commercial paper or other
senior Indebtedness of any Conduit Lender, it will not institute against, or
join any other Person in instituting against, such Conduit Lender any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceeding under the
laws of the United States or any State thereof. 
Notwithstanding anything to the contrary contained in this Agreement,
any Conduit Lender may (i) with notice to, but without prior consent of,
Duratek and the Administrative Agent and without paying any processing fee
therefor, assign all or any portion of its interest in any Loan to the Granting
Lender and (ii) disclose on a confidential basis any non-public
information relating to its funding of advances to any rating agency,
commercial paper dealer or provider of any surety or guarantee or credit or
liquidity enhancement to such Conduit Lender. 
This Section 11.5(h) may not
be amended without the prior written consent of each Granting Lender all or any
part of whose Loans are being funded by a Conduit Lender at the time of such
amendment.

 

(i)            Notwithstanding any contrary
provision of this Section 11.5,
any Lender may at any time pledge the Obligations held by it and such Lender’s
rights under this Agreement and the other Loan Documents to a Federal Reserve
Bank; provided that no such pledge to a Federal Reserve Bank shall release such
Lender from such Lender’s obligations hereunder or under any other Loan
Document.

 

87

 

Section 11.6           Accounting Principles.

 

Except as set forth in the following
sentence, references in this Agreement to GAAP shall be to such principles as
defined in Section 1.4, and all
accounting terms used herein without definition shall be used as defined under
GAAP.  All references to Operating Cash
Flow, Debt Service and other such terms shall be deemed to refer to such items
of Parent and its respective Subsidiaries on a consolidated basis, consistently
applied, unless otherwise indicated herein.

 

Section 11.7           Counterparts.

 

This Agreement may be executed in any number
of counterparts, each of which shall be deemed to be an original, but all such
separate counterparts shall together constitute but one and the same instrument.

 

Section 11.8           Governing Law and Jurisdiction.

 

(a)           THIS AGREEMENT, ANY NOTES AND ANY
LOAN DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE INTERNAL

NONEXCLUSIVE JURISDICTION OF ANY NEW YORK STATE COURT OR FEDERAL COURT OF THE
UNITED STATES OF AMERICA SITTING IN NEW YORK CITY, AND ANY APPELLATE COURT FROM
ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS TO WHICH IT IS A PARTY, OR FOR
RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH OF THE PARTIES HERETO
HEREBY IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY
SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH NEW YORK
STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY LAW, IN SUCH FEDERAL
COURT.  EACH OF THE PARTIES HERETO AGREES
THAT A FINAL NON-APPEALABLE JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE
CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE
JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW.  NOTHING IN THIS AGREEMENT SHALL AFFECT ANY
RIGHT THAT ANY PARTY MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING
RELATING TO THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS IN THE COURTS OF
ANY JURISDICTION.

 

(c)           EACH OF THE PARTIES HERETO IRREVOCABLY
AND UN-CONDITIONALLY WAIVES, TO THE FULLEST EXTENT IT MAY LEGALLY AND
EFFECTIVELY DO SO, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE

DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR
PROCEEDING IN ANY SUCH COURT.

 

88

 

Section 11.9           Severability.

 

Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall be ineffective to the
extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof in that jurisdiction or affecting the validity or
enforceability of such provision in any other jurisdiction.

 

Section 11.10         Interest.

 

(a)           In no event shall the amount of
interest due or payable hereunder or under any Notes exceed the maximum rate of
interest allowed by Applicable Law, and in the event any such payment is inadvertently
made by Duratek or inadvertently received by any Lender, then such excess sum
shall be credited as a payment of principal, unless Duratek shall notify the Administrative
Agent or such Lender in writing that it elects to have such excess returned
forthwith.  It is the express intent
hereof that Duratek not pay and the Lenders not receive, directly or indirectly
in any manner whatsoever, interest in excess of that which may legally be paid
by Duratek under Applicable Law.

 

(b)           Notwithstanding the use by the
Lenders of the Base Rate, the Federal Funds Rate and the Eurodollar Rate as
reference rates for the determination of interest on the Loans, the Lenders
shall be under no obligation to obtain funds from any particular source in
order to charge interest to Duratek at interest rates related to such reference
rates.

Commitment of the Loans provided in Section 2.4

If, in connection with any proposed change,
waiver, discharge or termination of or to any of the provisions of this
Agreement (other than as contemplated by clause (b) above), and the
consent of all Lenders required hereunder would have been obtained but for any
Lender’s failure to consent (such Lender, a “Non-Consenting Lender”) and
the consent of Majority Lenders is obtained but the consent of one or more of
such other Lenders whose consent is required is not obtained, then Duratek
shall have the right, so long as all Non-Consenting Lenders whose individual
consent is required are treated as described in either clause (i) or (ii) below,
to either (i) replace each such Non-Consenting Lender or Lenders (or, at
the option of Duratek if the respective Lender’s consent is required with
respect to less than all Loans (or related Commitments), to replace only the
Commitments and/or Loans of the respective Non-Consenting Lender that gave rise
to the need to obtain such Lender’s individual consent) with one or more
assignees pursuant to, and with the effect of an assignment under, Section 10.3 so long as at the time of such replacement,
each such assignee consents to the proposed change, waiver, discharge or termination
or (ii) terminate such Non-Consenting Lender’s Commitment (if such Lender’s
