WEATHERFORD INTERNATIONAL LTD.

7.00% Senior Note due 2038

     This Note is one of a duly authorized issue of Securities of the Company (which term includes
any successor corporation under the Indenture hereinafter referred to) designated as its 7.00%
Senior Notes due 2038 (the “Notes”), issued or to be issued pursuant to an Indenture dated as of
October 1, 2003, between the Company and Deutsche Bank Trust Company Americas, a New York banking
corporation, as Trustee (the “Trustee,” which term includes any successor trustee under such
Indenture), as amended and supplemented by the First Supplemental Indenture thereto dated as of
March 25, 2008 (such Indenture, as so amended and supplemented being referred to herein as the
“Indenture”). The terms of this Note include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939, as amended. Reference is hereby
made to the Indenture and all further supplemental indentures thereto for a statement of the
respective rights, limitation of rights, duties and immunities thereunder of the Company, the
Guarantor, the Trustee and the Holders and of the terms upon which the Notes are, and are to be,
authenticated and delivered.

     As provided in the Indenture, Securities may be issued in one or more series, which different
series may be issued in various aggregate principal amounts, may mature at different times, may
bear interest, if any, at different rates, may be subject to different redemption provisions, if
any, may be subject to different sinking, purchase or analogous funds, if any, may be subject to
different covenants and Events of Default and may otherwise vary as in the Indenture provided or
permitted. This Note is one of the series designated on the face hereof.

     This Note is the general, unsecured, senior obligation of the Company and is guaranteed
pursuant to a guarantee (the “Guarantee”) by Weatherford International, Inc., a Delaware
corporation (the “Guarantor”).

     The Notes are subject to redemption upon not less than 30 nor more than 60 days’ notice by
mail, at any time, as a whole or in part, at the election of the Company at a Redemption Price
equal to the greater of: (a) 100% of the principal amount of Securities then outstanding to be
redeemed, plus accrued and unpaid interest thereon to the redemption date; or (b) the sum of the
present values of the remaining scheduled payments of principal and interest on the Securities then
outstanding to be redeemed (not including any portion of such payments of interest accrued as of
the redemption date), discounted to the redemption date on a semi-annual basis (computed based on a
360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 45 basis
points (0.45%), as calculated by an Independent Investment Banker, plus accrued and unpaid interest
thereon to the redemption date; but interest installments whose Stated Maturity is on or prior to
such Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor
Securities, of record at the close of business on the relevant Record Dates referred to on the face
hereof, all as provided in the Indenture.

     “Adjusted Treasury Rate” means, with respect to any redemption date: (a) the yield, under the
heading which represents the average for the immediately preceding week, appearing in the most
recently published statistical release designated “H.15(519)” or any successor publication which is
published weekly by the Board of Governors of the Federal Reserve System and which establishes
yields on actively traded United States Treasury securities adjusted to constant maturity under the
caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury
Issue (if no maturity is within three months before or after the remaining life, as defined below,
yields for the two published maturities most closely corresponding to the Comparable Treasury Issue
will be determined and the Adjusted Treasury Rate will be interpolated or extrapolated from such
yields on a straight-line basis, rounding to the nearest month); or (b) if such release (or any
successor release) is not published during the week preceding the calculation date or does not
contain such yields, the rate per year equal to

 

 

the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated
using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Comparable Treasury Price for such redemption date. The Adjusted Treasury Rate will
be calculated on the third business day preceding the redemption date.

     “Comparable Treasury Issue” means the United States Treasury security selected by an
Independent Investment Banker as having a maturity comparable to the remaining term of the
Securities to be redeemed that would be used, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of such Securities.

     “Comparable Treasury Price” means (1) the average of five Reference Treasury Dealer Quotations
for the redemption date, after excluding the highest and lowest Reference Treasury Dealer
Quotations, or (2) if an Independent Investment Banker obtains fewer than five such Reference
Treasury Dealer Quotations, the average of all such quotations.

     “Independent Investment Banker” means Goldman, Sachs & Co., Deutsche Bank Securities Inc. or
Merrill Lynch, Pierce, Fenner & Smith Incorporated or any of their respective successors, as
designated by us, or if all such firms are unwilling or unable to serve as such, an independent
investment and banking institution of national standing appointed by the Company.

     “Reference Treasury Dealer” means: (a) Goldman, Sachs & Co., Deutsche Bank Securities Inc. and
Merrill Lynch, Pierce, Fenner & Smith Incorporated and each of their respective successors;
provided that, if any such Reference Treasury Dealer ceases to be a primary U.S. Government
securities dealer in the United States (Primary Treasury Dealer), the Company will substitute
another Primary Treasury Dealer; and (b) up to two other Primary Treasury Dealer selected by the
Company.

     “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer
and any redemption date, the average, as determined by an Independent Investment Banker, of the bid
and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to an Independent Investment Banker at 3:00 p.m., New York City
time, on the third business day preceding such redemption date.

     In the event of redemption of this Note in part only, a new Security or Securities of this
series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder
hereof upon the cancellation hereof.

     The Indenture permits, with certain exceptions as therein provided, the amendment thereof and
the modification of the rights and obligations of the Company and the Guarantor and the rights of
the Holders of the Securities of each series to be affected under the Indenture at any time by the
Company and the Guarantor and the Trustee with the consent of the Holders of a majority in
principal amount of the Securities at the time Outstanding of each series to be affected. The
Indenture also contains provisions permitting the Holders of specified percentages in principal
amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all
Securities of such series, to waive compliance by the Company and the Guarantor with certain
provisions of the Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such
Holder and upon all future Holders of this Note and of any Security issued upon the registration of
transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent
or waiver is made upon this Note.

 

 

     No reference herein to the Indenture and no provision of this Note or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the
principal of (and premium, if any) and interest on this Note at the times, place(s) and rate, and
in the coin or currency, herein prescribed.

     This Global Security or portion hereof may not be exchanged for Definitive Securities of this
series except in the limited circumstances provided in the Indenture. The holders of beneficial
interests in this Global Security will not be entitled to receive physical delivery of Definitive
Securities except as described in the Indenture and will not be considered the Holders thereof for
any purpose under the Indenture.

     The Notes are issuable only in registered form without coupons in denominations of U.S. $2,000
and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to
certain limitations therein set forth, Securities of this series are exchangeable for a like
aggregate principal amount of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

     Prior to due presentment of this Note for registration of transfer, the Company, the Trustee
and any agent of the Company, the Guarantor or the Trustee may treat the Person in whose name this
Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and
none of the Company, the Guarantor, the Trustee nor any such agent shall be affected by notice to
the contrary.

     No recourse under or upon any obligation, covenant or agreement of or contained in the
Indenture or of or contained in any Note, or the Guarantee endorsed thereon, or for any claim based
thereon or otherwise in respect thereof, or in any Security or in the Guarantee, or because of the
creation of any indebtedness represented thereby, shall be had against any incorporator,
shareholder, member, officer, manager or director, as such, past, present or future, of the Company
or the Guarantor or of any successor Person, either directly or through the Company or the
Guarantor or any successor Person, whether by virtue of any constitution, statute or rule of law,
or by the enforcement of any assessment, penalty or otherwise; it being expressly understood that
all such liability is hereby expressly waived and released by the acceptance hereof and as a
condition of, and as part of the consideration for, the Notes and the execution of the Indenture.

     The Indenture provides that the Company and the Guarantor (a) will be discharged from any and
all obligations in respect of the Notes (except for certain obligations described in the
Indenture), or (b) need not comply with certain restrictive covenants of the Indenture, in each
case if the Company or the Guarantor deposits, in trust, with the Trustee money or U.S. Government
Obligations (or a combination thereof) which through the payment of interest thereon and principal
thereof in accordance with their terms will provide money, in an amount sufficient to pay all the
principal of and interest on the Notes, but such money need not be segregated from other funds
except to the extent required by law.

     As more fully provided in the Indenture, no Holder may pursue any remedy under the Indenture
unless the Trustee shall have failed to act after notice of an Event of Default and written request
by Holders of at least 25% in principal amount of a series of the Securities and the offer to the
Trustee of indemnity satisfactory to it; however, such provision does not affect the right to sue
for enforcement of any overdue payment on any Security.

 

 

     Except as otherwise defined herein, all terms used in this Note which are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

     Customary abbreviations may be used in the name of a Holder or any assignee, such as: TEN COM
( = tenants in common), TEN ENT ( = tenants by the entireties), JT TEN ( = joint tenants with right
of survivorship and not as tenants in common), CUST ( = Custodian) and U/G/M/A ( = Uniform Gifts to
Minors Act).

     The Company will furnish to any holder of record of this Note, upon written request, without
charge, a copy of the Indenture. Requests may be made to: Weatherford International Ltd., 515 Post
Oak Blvd., Suite 600, Houston, Texas 77027, Attention: Corporate Secretary.

     This Note shall be governed by and construed in accordance with the laws of the State of New
York without regard to principles of conflicts of law.

     The Guarantor (which term includes any successor Person in such capacity under the Indenture),
has fully, unconditionally and absolutely guaranteed, to the extent set forth in the Indenture and
subject to the provisions in the Indenture, the due and punctual payment of the principal of, and
premium, if any, and interest on the Securities of this series and all other amounts due and
payable under the Indenture and such Securities by the Company.

     The obligations of the Guarantor to the Holders of Securities and to the Trustee pursuant to
the Guarantee and the Indenture are expressly set forth in Article Fourteen of the Indenture and
reference is hereby made to the Indenture for the precise terms of the Guarantee.

     NOW THEREFORE, the parties hereto agree as follows:

ARTICLE I

DEFINITIONS; ACCOUNTING TERMS; INTERPRETATION

     SECTION 1.01. Definitions. As used in this Agreement the following terms shall have the following meanings:

     “ABR”, when used in reference to any Loan or Borrowing, refers to whether such Loan,
or the Loans comprising such Borrowing, are bearing interest at a rate determined by reference to
the Alternate Base Rate.

     “Adjusted LIBO Rate” means, with respect to any Eurocurrency Borrowing for any
Interest Period, an interest rate per annum (rounded upwards, if necessary, to the next 1/100 of
1%) equal to (a) the LIBO Rate for such Interest Period multiplied by (b) the Statutory Reserve
Rate.

     “Administrative Agent” has the meaning specified in paragraph (c) on page one.

     “Administrative Questionnaire” means an Administrative Questionnaire in a form
supplied by the Administrative Agent.

     “Affiliate” means, with respect to any Person, any other Person that, directly or
indirectly, controls, is controlled by or is under direct or indirect common control with, such
Person. For the purposes of this definition, “control” (including, with correlative meanings, the
terms “controlling” and “controlled”), when used with respect to any Person, means the power
to

1

 

direct the management and policies of such Person, directly or indirectly, whether through the
ownership of voting securities, by contract or otherwise.

     “Agreement” means this Credit Agreement, as it may from time to time be further
amended, modified, restated or supplemented.

     “Alternate Base Rate” means, for any day, a rate per annum equal to the greatest of
(a) the Prime Rate in effect on such day, (b) the Base CD Rate in effect on such day plus 1% and
(c) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1%. If the Administrative
Agent shall have determined (which determination shall be presumed correct absent manifest error)
that it is unable to ascertain the Federal Funds Effective Rate for any reason, including the
inability or failure of the Administrative Agent to obtain sufficient quotations in accordance with
the terms of the definition thereof, the Alternate Base Rate shall be determined without regard to
clause (c) of the preceding sentence until the circumstances giving rise to such inability
no longer exist. Any change in the Alternate Base Rate due to a change in the Prime Rate, the Base
CD Rate or the Federal Funds Effective Rate shall be effective from and including the effective
date of such change in the Prime Rate, the Base CD Rate or the Federal Funds Effective Rate,
respectively.

     “Applicable Margin” means the per annum rate of interest set forth in the definition
of Applicable Rate under the heading “Applicable Margin”, based upon the ratings by Moody’s and
S&P, respectively, applicable on such date to the Index Debt.

     “Applicable Percentage” means, with respect to any Lender, the percentage of the total
Commitments represented by such Lender’s Commitment. If the Commitments have terminated or
expired, the Applicable Percentages shall be determined based upon the Commitments most recently in
effect, giving effect to any assignments.

     “Applicable Rate” means, for any day, with respect to any Eurocurrency Loan, or with
respect to the facility fees payable hereunder, as the case may be, the applicable rate per annum
set forth below under the captions “Facility Fee” or “Applicable Margin”, as the case may be, based
upon the ratings by Moody’s and S&P, respectively, applicable on such date to the Index Debt:

	 	 	 	 	 	 	 	 	 
	Index

	 	Facility	 	Applicable
	
Debt Ratings:
	 	Fee	 	Margin
	Performance Level I
	 	 	.050	%	 	 	.150	%
	Performance Level II
	 	 	.060	%	 	 	.190	%
	Performance Level III
	 	 	.080	%	 	 	.270	%
	Performance Level IV
	 	 	.090	%	 	 	.410	%
	Performance Level V
	 	 	.110	%	 	 	.590	%

; provided that for each day on which the total Revolving Credit Exposures of all Lenders
exceeds 50% of the total Commitments, (a) if the ratings established or deemed to have been
established by Moody’s and S&P for the Index Debt on such day shall fall within Performance

2

 

Level I, Performance Level II or Performance Level III, the Applicable Margin on such day shall be
increased by 0.05% and (b) if the ratings established or deemed to have been established by Moody’s
and S&P for the Index Debt on such day shall fall within Performance Level IV or Performance Level
V, the Applicable Margin on such day shall be increased by 0.10%.

     For purposes of the foregoing, (i) if either Moody’s or S&P shall not have in effect a rating
for the Index Debt (other than by reason of the circumstances referred to in the last sentence of
this definition), then such rating agency shall be deemed to have established the same rating as
the rating agency that has in effect a rating for the Index Debt; (ii) if the ratings established
or deemed to have been established by Moody’s and S&P for the Index Debt shall fall within
different Performance Levels, the Applicable Rate shall be based on the higher of the two ratings
unless one of the two ratings is two or more Performance Levels lower than the other, in which case
the Applicable Rate shall be determined by reference to the Performance Level next below that of
the higher of the two ratings; and (iii) if the ratings established or deemed to have been
established by Moody’s and S&P for the Index Debt shall be changed (other than as a result of a
change in the rating system of Moody’s or S&P), such change shall be effective as of the date on
which it is first announced by the applicable rating agency, irrespective of when or whether notice
of such change shall have been furnished by WIL to the Administrative Agent and the Lenders. Each
change in the Applicable Rate shall apply during the period commencing on the effective date of
such change and ending on the date immediately preceding the effective date of the next such
change. If the rating system of Moody’s or S&P shall change, or if either such rating agency shall
cease to be in the business of rating corporate debt obligations, WIL and the Lenders shall
negotiate in good faith to amend this definition to reflect such changed rating system or the
unavailability of ratings from such rating agency and, pending the effectiveness of any such
amendment, the Applicable Rate shall be determined by reference to the rating most recently in
effect prior to such change or cessation.

insurance by such Corporation of time deposits made in dollars at the offices of such member in the
United States; provided that if, as a result of any change in any law, rule or regulation, it is no

Required Lenders so that the criteria for evaluating the matters contemplated to be evidenced by
such covenants are substantially the same criteria as were effective prior to any such change in
GAAP, and (b) the Obligors shall be deemed to be in compliance with such covenants during the
60-day period following any such change, or until the earlier date of execution of such amendment,
if and to the
extent that the Obligors would have been in compliance therewith under GAAP as in effect
immediately prior to such change.

ARTICLE II

COMMITMENTS; LOANS

     SECTION 2.01. Loans.

          (a) Subject to the terms and conditions set forth herein, each Lender agrees to make Loans to
the Borrowers, in Dollars or any Optional Currency, from time to time during the Availability
Period in an aggregate principal amount that shall not result in (i) such Lender’s Revolving Credit
Exposure exceeding such Lender’s Commitment, (ii) the sum of the total Revolving Credit Exposures
of all Lenders exceeding the total Commitments, (iii) the sum of the total Revolving Credit
Exposures of all Lenders in respect of Loans denominated in Australian Dollars exceeding the
Australian Dollar Sublimit, (iv) the sum of the total Revolving Credit Exposures of all Lenders in
respect of Loans denominated in Canadian Dollars exceeding the Canadian Dollar Sublimit, (v) the
sum of the total Revolving Credit Exposures of all Lenders in respect of Loans denominated in Euros
exceeding the Euro Sublimit, (vi) the sum of the total Revolving Credit Exposures of all Lenders in
respect of Loans denominated in Norwegian Kroner exceeding the Norwegian Kroner Sublimit or (vii)
the sum of the total Revolving Credit Exposures of all Lenders in respect of Loans denominated in
Pounds Sterling exceeding the Pounds Sterling Sublimit. Within the foregoing limits and subject to
the terms and conditions set forth herein, the Borrowers may borrow, prepay and reborrow Loans.

          (b) Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders
ratably in accordance with their respective Commitments. The failure of any Lender to make any
Loan required to be made by it shall not relieve any other Lender of its obligations hereunder;
provided that the Commitments of the Lenders are several and no Lender shall be responsible for any
other Lender’s failure to make Loans as required.

          (c) Subject to Section 2.10, each Borrowing shall be comprised entirely of ABR Loans
or Eurocurrency Loans as a Borrower may request in accordance herewith. Eurocurrency Loans may be
denominated in Dollars or in an Optional Currency. All Loans denominated in an Optional Currency
must be Eurocurrency Loans. Each Lender at its option may make any Eurocurrency Loan by causing
any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any
exercise of such option shall not affect the

23

 

joint and several obligation of the Borrowers to repay
such Loan in accordance with the terms of this Agreement.

          (d) At the commencement of each Interest Period for any Eurocurrency Borrowing, such Borrowing
shall be in an aggregate amount that is an integral multiple of the Borrowing Multiple and not less
than the Borrowing Minimum. At the time that each ABR Borrowing is made, such ABR Borrowing shall
be in an aggregate amount that is an integral multiple of $500,000 and not less than $1,000,000;
provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused
balance of the total Commitments or that is required to finance the reimbursement of an LC
Disbursement as contemplated by Section 3.01(e). Borrowings of more than one Type may be
outstanding at the same time; provided that there shall not at any time be more than a total of
seven Eurocurrency Borrowings outstanding.

          (e) Notwithstanding any other provision of this Agreement, no Borrower shall be entitled to
request, or to elect to convert or continue, any Borrowing if the Interest Period requested with
respect thereto would end after the Maturity Date.

     SECTION 2.02. Requests for Borrowings. To request a Borrowing, a Borrower shall notify the
Administrative Agent (and the Administrative Agent shall promptly thereafter notify the Lenders) of
such request by telephone (a) in the case of a Eurocurrency Borrowing, not later than 11:00 a.m.,
New York City time, three Business Days before the date of the proposed Borrowing or (b) in the
case of an ABR Borrowing, not later than 11:00 a.m., New York City time, on the date of the
proposed Borrowing; provided that any such notice of an ABR Borrowing to finance the reimbursement
of an LC Disbursement as contemplated by Section 3.01(e) may be given not later than 10:00
a.m., New York City time, on the date of the proposed Borrowing. Each such telephonic Borrowing
Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the
Administrative Agent of a written Borrowing Request signed by the Borrower requesting the
Borrowing. Each such telephonic and written Borrowing Request shall specify the following
information in compliance with Section 2.01:

     (i) the aggregate amount of the requested Borrowing;

     (ii) the date of such Borrowing, which shall be a Business Day;

     (iii) whether such Borrowing is to be an ABR Borrowing or a Eurocurrency Borrowing;

     (iv) in the case of a Eurocurrency Borrowing, the applicable Currency in which such
Borrowing is to be made;

     (v) in the case of a Eurocurrency Borrowing, the initial Interest Period to be
applicable thereto, which shall be a period contemplated by the definition of the term
“Interest Period”; and

24

 

     (vi) the location and number of the account of the requesting Borrower to which funds
are to be disbursed, which shall comply with the requirements of Section 2.03.

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an
ABR Borrowing. If no Currency is specified with respect to any requested Eurocurrency Borrowing,
then the requesting Borrower shall be deemed to have requested that such Eurocurrency Borrowing be
made in Dollars. If no Interest Period is specified with respect to any requested Eurocurrency
Borrowing, then the requesting Borrower shall be deemed to have selected an Interest Period of one
month’s duration. Promptly following receipt of a Borrowing Request in accordance with this
Section, the Administrative Agent shall advise each Lender of the details thereof and of the amount
of, and applicable Currency of, such Lender’s Loan to be made as part of the requested Borrowing.

     SECTION 2.03. Funding of Borrowings.

          (a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof
by wire transfer of immediately available funds in the applicable Currency (i) by 12:00 noon, New
York City time, in the case of a Borrowing consisting of Eurocurrency Loans, and (ii) by 1:00 p.m.,
New York City time, in the case of a Borrowing consisting of ABR Loans, to the account of the
Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The
Administrative Agent shall make such Loans available to the requesting Borrower by promptly
crediting the amounts so received in like funds to an account of such Borrower maintained with the
Administrative Agent in New York, New York and designated by such Borrower in the applicable
Borrowing Request; provided that an ABR Borrowing made to finance the reimbursement of an LC
Disbursement as provided in Section 3.01(e) shall be remitted by the Administrative Agent
to the Issuing Bank.

          (b) Unless the Administrative Agent shall have received notice from a Lender prior to the
proposed date of any Borrowing of Eurocurrency Loans (or, in the case of any Borrowing of ABR
Loans, prior to 12:00 noon, New York City time, on the date of such Borrowing) that such Lender
shall not make available to the Administrative Agent such Lender’s share of such Borrowing, the
Administrative Agent may assume that such Lender has made such share available on such date in
accordance with paragraph (a) of this Section and may, in reliance upon such assumption,
make available to the requesting Borrower a corresponding amount. In such event, if a Lender has
not in fact made its share of the applicable Borrowing available to the Administrative Agent, then
the Borrowers, jointly and severally, and the applicable Lender severally agree to pay to the
Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each
day from and including the date such amount is made available to the requesting Borrower to but
excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the
greater of (A) the Federal Funds Effective Rate, in the case of Loans denominated in Dollars, and the rate reasonably
determined by the Administrative Agent to be the cost to it of funding such amount, in the case of
Loans denominated in an Optional Currency, and (B) a rate determined by the Administrative Agent in
accordance with banking industry rules on interbank compensation or (ii) in the case of the
Borrowers, the interest rate applicable to ABR Borrowings, in the case of Loans denominated in
Dollars, and the interest rate applicable to such Borrowing, in the case of Loans denominated in

25

 

any other currency. If such Lender pays such amount to the Administrative Agent, then such amount
shall constitute such Lender’s Loan included in such Borrowing.

     SECTION 2.04. Interest Elections.

          (a) Each Borrowing initially shall be of the Type specified in the applicable Borrowing
Request and, in the case of a Eurocurrency Borrowing, shall have an initial Interest Period and
shall be denominated in such Currency, in each case as specified in such Borrowing Request.
Thereafter, a Borrower may elect to convert such Borrowing to a different Type or to continue such
Borrowing and, in the case of a Eurocurrency Borrowing, may elect Interest Periods and Currencies
therefor, all as provided in this Section. A Borrower may elect different options with respect to
different portions of the affected Borrowing, in which case each such portion shall be allocated
ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising
each such portion shall be considered a separate Borrowing.

          (b) To make an election pursuant to this Section, a Borrower shall notify the Administrative
Agent of such election by telephone by the time that a Borrowing Request would be required under
Section 2.02 if such Borrower were requesting a Borrowing of the Type and Currency
resulting from such election to be made on the effective date of such election. Each such
telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand
delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form
approved by the Administrative Agent and signed by such Borrower. Notwithstanding any other
provision of this Section, no Borrower shall be permitted to change the currency of any Borrowing.

          (c) Each telephonic and written Interest Election Request shall specify the following
information in compliance with Section 2.02:

     (i) the Borrowing to which such Interest Election Request applies and, if different
options are being elected with respect to different portions thereof, the portions thereof
to be allocated to each resulting Borrowing (in which case the information to be specified
pursuant to clauses (iii) and (iv) below shall be specified for each
resulting Borrowing);

     (ii) the effective date of the election made pursuant to such Interest Election
Request, which shall be a Business Day;

     (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurocurrency
Borrowing; and

     (iv) if the resulting Borrowing is a Eurocurrency Borrowing, the Interest Period to be
applicable thereto after giving effect to such election, which shall be a period
contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurocurrency Borrowing but does not specify an
Interest Period, then the Borrower making such Interest Election Request shall be deemed to have
selected an Interest Period of one month’s duration.

26

 

          (d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall
advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

          (e) If a Borrower fails to deliver a timely Interest Election Request with respect to a
Eurocurrency Borrowing prior to the end of the Interest Period applicable thereto, then, unless
such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing
shall (i) in the case of a Borrowing denominated in Dollars, be converted to an ABR Borrowing and
(ii) in the case of a Borrowing denominated in an Optional Currency, be converted to an ABR
Borrowing (denominated in Dollars) in an amount equal to the Dollar Equivalent of such Eurocurrency
Borrowing on the last day of such Interest Period. Notwithstanding any contrary provision hereof,
if an Event of Default has occurred and is continuing and the Administrative Agent, at the request
of the Required Lenders, so notifies WIL, then, so long as an Event of Default is continuing (1) no
outstanding Borrowing may be converted to or continued as a Eurocurrency Borrowing and (2) unless
repaid, each Eurocurrency Borrowing shall at the end of the Interest Period applicable thereto (A)
in the case of a Borrowing denominated in Dollars, be converted to an ABR Borrowing, and (B) in the
case of a Borrowing denominated in an Optional Currency, be converted to an ABR Borrowing
(denominated in Dollars) in an amount equal to the Dollar Equivalent of such Eurocurrency Borrowing
on the last day of such Interest Period.

     SECTION 2.05. Termination and Reduction of Commitments.

          (a) Unless previously terminated, the Commitments shall terminate on the Maturity Date.

          (b) WIL may at any time terminate, or from time to time reduce, the Commitments; provided that
(i) each reduction of the Commitments shall be in an amount that is an integral multiple of
$1,000,000 and not less than $5,000,000 and (ii) WIL shall not terminate or reduce the Commitments
if, after giving effect to any concurrent prepayment of the Loans in accordance with Section
2.07, the Revolving Credit Exposures would exceed the total Commitments.

          (c) WIL shall notify the Administrative Agent of any election to terminate or reduce the
Commitments under paragraph (b) of this Section 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 WIL pursuant to this Section shall be
irrevocable; provided that a notice of termination of the Commitments delivered by WIL may
state that such notice is conditioned upon the effectiveness of other credit facilities, in which
case such notice may be revoked by WIL (by notice to the Administrative Agent on or prior to the
specified effective date) if such condition is not satisfied. Any termination or reduction of the
Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the
Lenders in accordance with their respective Commitments, and each such reduction of each such
Lender’s Commitment shall be applied to the reduction of such Lender’s commitment to make Loans and
acquire LC Exposure in the same proportion as each such commitment bears to such Lender’s total
Commitment immediately prior to such reduction.

27

 

     SECTION 2.06. Repayment of Loans; Evidence of Debt.

          (a) The Borrowers hereby jointly and severally and unconditionally promise to pay to the
Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan
on the Maturity Date.

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

          (c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount
of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the
amount of any principal or interest due and payable or to become due and payable from each Borrower
to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent
hereunder for the account of the Lenders and each Lender’s share thereof.

          (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of
this Section shall be prima facie evidence of the existence and amounts of the obligations recorded
therein; provided that the failure of any Lender or the Administrative Agent to maintain such
accounts or any error therein shall not in any manner affect the obligation of the Borrowers,
jointly and severally, to repay the Loans in accordance with the terms of this Agreement.

          (e) Any Lender may request that Loans made by it be evidenced by a promissory note (all of
such notes being hereinafter collectively referred to as the “Notes”). In such event, the
Borrowers shall prepare, execute and deliver to such Lender a promissory note payable, jointly and
severally, to the order of such Lender and in the form of Exhibit D. Thereafter, the Loans
evidenced by such promissory note and interest thereon shall at all times (including after
assignment pursuant to Section 12.05) be represented by one or more Notes in such form
payable to the order of the payee named therein.

     SECTION 2.07. Prepayment of Loans.

          (a) The Borrowers shall have the right at any time and from time to time to prepay any
Borrowing in whole or in part, subject to prior notice in accordance with paragraph (b) of
this Section.

          (b) A Borrower shall notify the Administrative Agent by telephone (promptly confirmed by
telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurocurrency Borrowing,
not later than 11:00 a.m., New York City time, three Business Days before the date of prepayment,
or (ii) in the case of prepayment of an ABR Borrowing, not later than 11:00 a.m., New York City
time, one Business Day before the date of prepayment. Each such notice shall be irrevocable and
shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to
be prepaid; provided that, if a notice of prepayment is given in connection with a conditional
notice of termination of the Commitments as contemplated by Section 2.05, then such notice
of prepayment may be revoked if such notice of termination is revoked in accordance with
Section 2.05. Promptly following receipt of any such

28

 

notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of
any Borrowing shall be in an amount that would be permitted in the case of an advance of a
Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing
shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be
accompanied by accrued interest to the extent required by Section 2.09. All prepayments
under this Section 2.07(b) shall be subject to Section 2.12.

          (c) On the date that a Change of Control of the type described in clause (a)(iii) of
the definition of such term occurs and on the date that is 15 days after the occurrence of any
other type of Change of Control, the Commitments shall terminate and the Borrowers (i) jointly and
severally, shall prepay the principal amount of the Loans and all accrued and unpaid interest
thereon in immediately available funds and (ii) deposit in an account with the Administrative
Agent, in the name of the Administrative Agent for the benefit of the Lenders, an amount in cash
equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon. Such
deposit shall be held by the Administrative Agent for the payment of LC Exposure. The
Administrative Agent shall have exclusive dominion and control, including the exclusive right of
withdrawal, over such account. Such deposits shall be invested so as to earn interest at such rate
on overnight deposits as the Administrative Agent may reasonably obtain, but such investments shall
be made at the Borrowers’ risk and expense. Interest or profits, if any, on such investments shall
accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to
reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the
extent not so applied, shall be held for the satisfaction of the joint and several reimbursement
obligations of the Borrowers for the LC Exposure at such time. Moneys in such account (to the
extent not applied as aforesaid) shall be returned to the applicable Borrower within three Business
Days after all LC Exposure shall have been reduced to zero.

     SECTION 2.08. Fees.

          (a) The Borrowers, jointly and severally, agree to pay to the Administrative Agent for the
account of each Lender a facility fee, which shall accrue at the Facility Fee Rate on
the daily amount of the Commitment of such Lender (whether used or unused) during the period
from and including the Effective Date to but excluding the date on which such Lender ceases to have
any Revolving Credit Exposure. Accrued facility fees shall be payable in arrears on the last day
of March, June, September and December of each year and on the date on which the Commitments
terminate, commencing on the first such date to occur after the date hereof; provided that any
facility fees accruing after the date on which the Commitments terminate shall be payable on
demand. All facility fees shall be computed on the basis of a year of 365 or 366 days, as
applicable, and shall be payable for the actual number of days elapsed (including the first day but
excluding the last day).

          (b) The Borrowers, jointly and severally, agree to pay (i) to the Administrative Agent for the
account of each Lender a participation fee with respect to its participations in Letters of Credit,
which shall accrue at the same Applicable Margin used to determine the interest rate applicable to
Eurocurrency Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion
thereof attributable to unreimbursed LC

29

 

Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates
and the date on which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a
fronting fee, which shall accrue at the rate of .125% per annum on the average daily amount of the
LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during
the period from and including the Effective Date to but excluding the later of the date of
termination of the Commitments and the date on which there ceases to be any LC Exposure (which
shall in any event be a minimum of $500.00 per annum for each Letter of Credit), as well as the
Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any
Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees
accrued through and including the last day of March, June, September and December of each year
shall be payable in Dollars on the third Business Day following such last day, commencing on the
first such date to occur after the Effective Date; provided that all such fees shall be payable on
the date on which the Commitments terminate and any such fees accruing after the date on which the
Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank
pursuant to this paragraph shall be payable in Dollars within 10 days after demand. All
participation fees and fronting fees shall be computed on the basis of a year of 365 or 366 days,
as applicable, and shall be payable for the actual number of days elapsed (including the first day
but excluding the last day).

          (c) The Borrowers, jointly and severally, agree to pay to the Administrative Agent, for its
own account, fees payable in the amounts and at the times separately agreed upon between WIL and
the Administrative Agent.

          (d) All fees payable hereunder shall be paid on the dates due, in immediately available funds,
to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for
distribution, in the case of facility fees and participation fees, to the Lenders. Fees paid shall
not be refundable under any circumstances.

     SECTION 2.09. Interest.

          (a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate.

          (b) The Loans comprising each Eurocurrency Borrowing shall bear interest at the Adjusted LIBO
Rate for the Interest Period in effect for such Borrowing.

          (c) Interest on each Loan shall be paid in the Currency in which the principal amount of such
Loan is denominated.

          (d) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or
other amount payable by the Borrowers hereunder is not paid when due, whether at stated maturity,
upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before
judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus
the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section
or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Borrowings as provided
in paragraph (a) of this Section.

30

 

          (e) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date
for such Loan and upon termination of the Commitments; provided that (i) interest accrued pursuant
to paragraph (d) of this Section shall be payable on demand, (ii) in the event of any
repayment or prepayment of any Loan (other than a prepayment of an ABR Loan prior to the end of the
Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable
on the date of such repayment or prepayment and (iii) in the event of any conversion of any
Eurocurrency Loan prior to the end of the current Interest Period therefor, accrued interest on
such Loan shall be payable on the effective date of such conversion.

          (f) All interest hereunder shall be computed on the basis of a year of 360 days, except that
interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is
based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap
year), and in each case shall be payable for the actual number of days elapsed (including the first
day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO
Rate shall be determined by the Administrative Agent, and such determination shall be presumed
correct absent manifest error.

     SECTION 2.10. Alternate Rate of Interest. If prior to the commencement of any Interest
Period for a Eurocurrency Borrowing denominated in any Currency:

          (a) the Administrative Agent determines (which determination shall be presumed correct absent
manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO
Rate or the LIBO Rate, as applicable, for such Currency for such Interest Period; or

          (b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or
the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the
cost to such Lenders of making or maintaining their Loans included in such Borrowing for such
Interest Period;

then the Administrative Agent shall give notice thereof to WIL and the Lenders by telephone or
telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies WIL and
the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any ABR Borrowing to, or continuation of any
Eurocurrency Borrowing as, a Eurocurrency Borrowing in such Currency shall be ineffective, and, in
the case of any request for the continuation of a Eurocurrency Borrowing, such Eurocurrency
Borrowing shall on the last day of the Interest Period applicable thereto be converted to (A) in
the case of a Eurocurrency Borrowing denominated in Dollars, an ABR Borrowing or (B) in the case of
a Eurocurrency Borrowing denominated in an Optional Currency, an ABR Borrowing (denominated in
Dollars) in an amount equal to the Dollar Equivalent of the amount of such Eurocurrency Borrowing,
and (ii) if any Borrowing Request requests a Eurocurrency Borrowing in such Currency, such
Borrowing shall be made as an ABR Borrowing in an amount equal to the Dollar Equivalent of the
amount of the requested Eurocurrency Borrowing.

31

 

     SECTION 2.11. Increased Costs.

     (a) If any Change in Law shall:

     (i) impose, modify or deem applicable any reserve, special deposit or similar
requirement against assets of, deposits with or for the account of, or credit extended by,
any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or the
Issuing Bank; or

     (ii) impose on any Lender or the Issuing Bank or the London interbank market any other
condition affecting this Agreement or Eurocurrency Loans made by such Lender or any Letter
of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurocurrency Loan (or of maintaining its obligation to make any such Loan) or to
increase the cost to such Lender or the Issuing Bank of participating in, issuing or maintaining
any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or
the Issuing Bank hereunder (whether of principal, interest or otherwise), then the Borrowers,
jointly and severally, shall pay to such Lender or the Issuing Bank, as the case may be, such
additional amount or amounts as shall compensate such Lender or the Issuing Bank, as the case may
be, for such additional costs incurred or reduction suffered.

          (b) If any Lender or the Issuing Bank determines that any Change in Law regarding capital
requirements has or would have the effect of reducing the rate of return on such Lender’s or the
Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if
any, as a consequence of this Agreement or the Loans made by, or participations in Letters of
Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below
that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company
could have achieved but for such Change in Law (taking into consideration such Lender’s or the
Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with respect to capital adequacy), then from time to
time the Borrowers, jointly and severally, shall pay to such Lender or the Issuing Bank, as the
case may be, such additional amount or amounts as shall compensate such Lender or the Issuing Bank
or such Lender’s or the Issuing Bank’s holding company for any such reduction suffered.

          (c) A certificate of a Lender or the Issuing Bank setting forth the amount or amounts
necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be,
as specified in paragraph (a) or (b) of this Section, along with (i) a calculation
of such amount or amounts, (ii) a description of the specific Change in Law that justifies such
amounts due, and (iii) such other pertinent information related to the foregoing as any Borrower
may reasonably request, shall be delivered to such Borrower and shall be presumed correct absent
manifest error. The Borrowers, jointly and severally, shall pay such Lender or the Issuing Bank,
as the case may be, the correct amount shown as due on any such certificate within 10 days after
receipt thereof.

          (d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation
pursuant to this Section shall not constitute a waiver of such Lender’s or the

32

 

Issuing Bank’s right to demand such compensation; provided that no Borrower shall be required to compensate a Lender or
the Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than
120 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the
Borrowers of the Change in Law giving rise to such increased costs or reductions and of such
Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided further that, if
the Change in Law giving rise to such increased costs or reductions is retroactive, then the
120-day period referred to above shall be extended to include the period of retroactive effect
thereof.

     SECTION 2.12. Break Funding Payments. In the event of (a) the payment of any principal of
any Eurocurrency Loan other than on the last day of an Interest Period applicable thereto
(including as a result of an Event of Default), (b) the conversion of any Eurocurrency Loan other
than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert,
continue or prepay any Eurocurrency Loan on the date specified in any notice delivered pursuant
hereto (regardless of whether such notice may be revoked under Section 2.07(b) and is
revoked in accordance therewith), or (d) the assignment of any Eurocurrency Loan other than on the
last day of the Interest Period applicable thereto as a result of an assignment required by WIL
pursuant to Section 4.03(b), then, in any such event, the Borrowers, jointly and severally,
shall compensate each Lender for the loss, cost and expense attributable to such event. In the
case of a Eurocurrency Loan, such loss, cost or expense to any Lender shall be deemed to include an
amount determined by such Lender to be the excess, if any, of (i) the amount of interest which
would have accrued on the principal amount of such Loan had such event not occurred, at the
Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of
such event to the last day of the then current Interest Period therefor (or, in the case of a
failure to borrow, convert or continue, for the period that would have been the Interest Period for
such Loan), over (ii) the amount of interest which would accrue on such principal amount for such
period at the interest rate which such Lender would bid were it to bid, at the commencement of such
period, for deposits in the applicable currency of a comparable amount and period from other banks
in the eurocurrency market. A certificate of any Lender setting forth any amount or amounts that such Lender is
entitled to receive pursuant to this Section shall be delivered to the Borrowers and shall be
presumed correct absent manifest error, and shall set forth a calculation of such amounts and such
other information as any Borrower may reasonably request. The Borrowers, jointly and severally,
shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt
thereof.

     SECTION 2.13. Agreement to Defer Exercise of Right of Contribution, Etc. Notwithstanding
any payment or payments made by a Borrower (a “Paying Borrower”) hereunder, or any setoff
or application by the Administrative Agent or any Lender of any security furnished by, or of any
credits or claims against, such Paying Borrower, if an Event of Default has occurred and is
continuing, such Paying Borrower will not assert or exercise any rights of the Administrative Agent
or any Lender or of its own, against any other Borrower to recover the amount of any such payment,
setoff or application by the Administrative Agent or any Lender, whether by way of assertion of any
claim, or exercise of any remedy or right of subrogation, reimbursement, exoneration, contribution,
indemnification, participation or otherwise, and whether arising by contract, by statute, under
common law or otherwise, and, if an Event of Default has occurred and is continuing, such Paying
Borrower shall not have any right to exercise any right of recourse to or any claim against assets
or property of the other

33

 

Borrowers for such amounts, in each case unless and until all of the
Obligations of the Borrowers have been fully and finally satisfied. If any amount shall be paid to
a Paying Borrower by any other Borrower after payment in full of the Obligations, and the
Obligations shall thereafter be reinstated in whole or in part and the Administrative Agent or any
Lender forced to repay to any Borrower any sums received in payment of the Obligations, the
obligations of each Borrower hereunder shall be automatically pro tanto reinstated and such amount
shall be held in trust by the payee thereof for the benefit of the Administrative Agent and the
Lenders and shall forthwith be paid to the Administrative Agent to be credited and applied to the
Obligations, whether matured or unmatured.

     SECTION 2.14. Extension of Maturity Date.

          (a) Not earlier than 90 days prior to, nor later than 30 days prior to, each May 2 occurring
hereafter, beginning with May 2, 2011, and on not more than three occasions, WIL may, upon notice
to the Administrative Agent (which shall promptly notify the Lenders), request a one-year extension
of the Maturity Date then in effect. Prior to the earlier of (i) 30 days after delivery of such
notice by the Administrative Agent to the Lenders and (ii) three Business Days prior to the then
existing Maturity Date, each Lender shall notify the Administrative Agent whether or not it
consents to such extension (which consent may be given or withheld in such Lender’s sole and
absolute discretion). Any Lender not responding within the above time period shall be deemed not
to have consented to such extension. The Administrative Agent shall promptly notify the Borrowers
and the Lenders of the Lenders’ responses.

          (b) The Maturity Date shall be extended only if the Required Lenders (calculated excluding any
Lender in default in its obligation to fund Loans hereunder and after giving effect to any replacements of Non-Extending Lenders pursuant to Section
4.03(b)) have consented thereto, whereupon the Maturity Date shall be extended to the date
which is one year after the Maturity Date in effect prior to such extension (such existing Maturity
Date, the “Extension Effective Date”). The Administrative Agent shall promptly notify the
Lenders of such extension, specifying the Extension Effective Date and the new Maturity Date. As a
condition precedent to such extension, each Obligor shall deliver to the Administrative Agent a
certificate of such Obligor dated as of the Extension Effective Date (in sufficient copies for each
Lender) signed by a Responsible Officer of such Obligor (i) certifying and attaching the
resolutions adopted by such Obligor approving or consenting to such extension and (ii) certifying
that (A) before and after giving effect to such extension, the representations and warranties
contained in Article VI made by it are true and correct on and as of the Extension
Effective Date, except to the extent that such representations and warranties specifically refer to
an earlier date, (B) as of the Extension Effective Date, both before and immediately after giving
effect to such extension no Default or Event of Default has occurred and is continuing, and (C) as
of the Extension Effective Date, there has been no material adverse change, since the date of the
most recent Annual Report on Form 10-K furnished or deemed furnished to the Administrative Agent
and each Lender pursuant to Section 7.01(b), in the financial condition, business or
operations of WIL and its Subsidiaries taken as a whole which could reasonably be expected to have
a Material Adverse Effect.

34

 

          (c) Notwithstanding any extension of the Maturity Date pursuant to this Section 2.14,
each Non-Extending Lender that has not been replaced by another Lender pursuant to Section
4.03 prior to the applicable Extension Effective Date shall continue to be subject to the
Maturity Date in effect prior to giving effect to such extension (the “Existing Maturity
Date”), and references herein to the “Maturity Date”, as to such Non-Extending Lender, shall be
deemed to refer to the Existing Maturity Date. On the Existing Maturity Date, the Borrowers shall
(i) prepay any Loans outstanding on such date (and pay any additional amounts required pursuant to
Section 2.12) to the extent necessary to keep outstanding Loans ratable with any revised
Applicable Percentages of the respective Lenders effective as of such date and (ii) pay all other
obligations accrued or owing hereunder to each Non-Extending Lender as of the Existing Maturity
Date.

     SECTION 2.15. Increase in Commitments.

          (a) Subject to the terms and conditions set forth herein, WIL shall have the right, without
the consent of the Lenders but with the prior approval of the Administrative Agent and the Issuing
Bank (not to be unreasonably withheld, delayed or conditioned), to cause from time to time an
increase in the aggregate Commitments (a “Commitment Increase”) by adding to this Agreement
one or more additional financial institutions that are not already Lenders hereunder and that are
reasonably satisfactory to the Administrative Agent and the Issuing Bank (each a “CI
Lender”) or by allowing one or more existing Lenders to increase their respective Commitments;
provided that (i) no Event of Default shall have occurred and be continuing on the effective date
of such Commitment Increase, (ii) no such Commitment Increase shall be in an amount less than
$15,000,000, (iii) no such Commitment Increase shall cause the aggregate Commitments to exceed
$500,000,000, (iv) no Lender’s Commitment shall be increased without such Lender’s prior written consent (which consent may be given or withheld in such Lender’s
sole and absolute discretion) and (v) if, on the effective date of such Commitment Increase, any
Loans have been funded, then the Borrowers shall be obligated to pay any breakage fees or costs or
other amounts owing hereunder in connection with the breakage or reallocation of such outstanding
Loans.

          (b) Any Commitment Increase must be requested by written notice from WIL to the Administrative
Agent (a “Notice of Commitment Increase”) in the form of Exhibit E attached hereto
and shall be subject to the approval of the Administrative Agent and the Issuing Bank, such
approval not to be unreasonably withheld, delayed or conditioned. Each such Notice of Commitment
Increase shall specify (i) the proposed effective date of such Commitment Increase, which date
shall be no earlier than five (5) Business Days after receipt by the Administrative Agent of such
Notice of Commitment Increase, (ii) the amount of the requested Commitment Increase (provided that
after giving effect to such requested Commitment Increase, the aggregate Commitments do not exceed
the amount set forth in subparagraph (a)(iii) above), (iii) the identity of each CI Lender
or Lender that has agreed in writing to increase its Commitment hereunder, and (iv) the amount of
the respective Commitments of the then existing Lenders and the CI Lenders from and after the
Commitment Increase Effective Date. The Administrative Agent and the Issuing Bank shall review
each Notice of Commitment Increase and shall notify WIL whether or not the Administrative Agent and
the Issuing Bank approve the proposed Commitment Increase, such approval not to be unreasonably
withheld, delayed or conditioned. If the Administrative Agent and the Issuing Bank approve such
Commitment

35

 

Increase, the Administrative Agent and the Issuing Bank shall execute a counterpart to
the Notice of Commitment Increase and such Commitment Increase shall be effective on the proposed
effective date set forth in such notice (if the Administrative Agent and the Issuing Bank consented
to such Commitment Increase prior to such proposed date) or on another date as determined by WIL
and agreed to by the Administrative Agent and the Issuing Bank (such date referred to herein as the
“Commitment Increase Effective Date”).

          (c) On each Commitment Increase Effective Date, to the extent that there are Loans outstanding
as of such date, (i) each CI Lender shall, by wire transfer of immediately available funds, deliver
to the Administrative Agent such CI Lender’s New Funds Amount of each applicable Currency, which
amounts, for each such CI Lender, shall constitute Loans made by such CI Lender to the Borrowers
pursuant to this Agreement on such Commitment Increase Effective Date, (ii) the Administrative
Agent shall, by wire transfer of immediately available funds, pay to each Reducing Percentage
Lender its Reduction Amount of each applicable Currency, which amounts, for each such Reducing
Percentage Lender, shall constitute a prepayment by the Borrowers pursuant to Section
2.07(a), ratably in accordance with the respective principal amounts thereof, of the principal
amounts of all then outstanding Loans of such Reducing Percentage Lender, and (iii) the Borrowers
shall pay to each Lender any breakage fees or costs or other amounts owing hereunder in connection
with the breakage or reallocation of any outstanding Loans.

          (d) For purposes of this Section 2.15 and Exhibit E, the following defined
terms shall have the following meanings: (i) “New Funds Amount” means, for any Lender or
CI Lender and for any Currency, the amount equal to the product of such Lender’s increased
Commitment or such CI Lender’s Commitment (as applicable) represented as a percentage of the
aggregate Commitments after giving effect to the Commitment Increase, times the aggregate
principal amount of the outstanding Loans denominated in such Currency immediately prior to giving
effect to the Commitment Increase, if any, as of a Commitment Increase Effective Date (without
regard to any increase in the aggregate principal amount of Loans as a result of borrowings made
after giving effect to the Commitment Increase on such Commitment Increase Effective Date); (ii)
“Reducing Percentage Lender” means each then existing Lender immediately prior to giving
effect to a Commitment Increase that does not increase its respective Commitment as a result of
such Commitment Increase and whose relative percentage of the aggregate Commitments shall be
reduced after giving effect to such Commitment Increase; and (iii) “Reduction Amount”
means, for any Reducing Percentage Lender and for any Currency, the amount by which such Reducing
Percentage Lender’s outstanding Loans denominated in such Currency decrease as of a Commitment
Increase Effective Date (without regard to the effect of any borrowings made on such Commitment
Increase Effective Date after giving effect to the applicable Commitment Increase).

          (e) Each Commitment Increase shall become effective on the Commitment Increase Effective Date
with respect thereto and upon such effectiveness (i) the Administrative Agent shall record in the
register each CI Lender’s information as provided in the applicable Notice of Commitment Increase
and pursuant to an Administrative Questionnaire satisfactory to the Administrative Agent that shall
be executed and delivered by each CI Lender to the Administrative Agent on or before such
Commitment Increase Effective Date, (ii) Schedule 1.01 (if applicable) and Schedule
2.01 hereto shall be automatically amended and restated to set forth

36

 

all Lenders (including any CI Lenders) that will be Lenders hereunder after giving effect to such Commitment Increase (as set
forth in Annex I to the applicable Notice of Commitment Increase), and the Administrative Agent
shall distribute to each Lender (including each CI Lender) a copy of such amended and restated
Schedule 1.01 (if applicable) and Schedule 2.01, and (iii) each CI Lender
identified on the Notice of Commitment Increase for such Commitment Increase shall be a “Lender”
for all purposes under this Agreement.

     SECTION 2.16. Currency Fluctuation. If as a result of fluctuations in currency exchange
rates (which shall be calculated by the Administrative Agent on each Revaluation Date and in any
case no less often than monthly), the Administrative Agent notifies the Borrowers in writing that
the aggregate of the Revolving Credit Exposures of the Lenders exceeds 105% of the aggregate
Commitments, the Borrowers shall within 5 Business Days after receipt of such notice prepay
outstanding Loans in an amount equal to such excess or, if such excess is greater than the amount
of all outstanding Loans, shall within 5 Business Days prepay all outstanding Loans and deliver to
the Administrative Agent cash collateral in an amount equal to the remaining excess after giving
effect to such prepayment.

ARTICLE III

LETTERS OF CREDIT

     SECTION 3.01. Letters of Credit.

          (a) General. Subject to the terms and conditions set forth herein, a Borrower may
request the issuance of Letters of Credit, denominated in Dollars, for its own account, in a form
reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time
to time during the Availability Period. In the event of any inconsistency between the terms and
conditions of this Agreement and the terms and conditions of any form of letter of credit
application or other agreement submitted by a Borrower to, or entered into by a Borrower with, the
Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall
control. Nothing contained in this Article III is intended to limit or restrict the rights
of any Borrower or any Subsidiary to obtain letters of credit from any Person, regardless of
whether such Person is a party hereto.

          (b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request
the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter
of Credit), a Borrower shall hand deliver or telecopy (or transmit by electronic communication, if
arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the
Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal
or extension) a Letter of Credit Request requesting the issuance of a Letter of Credit, or
identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of
issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such
Letter of Credit is to expire (which shall comply with paragraph (c) of this Section
3.01), the amount of such Letter of Credit, the name and address of the beneficiary thereof and
such other information as shall be necessary to prepare, amend, renew or extend such Letter of
Credit. If requested by the Issuing Bank, a Borrower also shall submit a letter of credit
application on the Issuing Bank’s standard form in connection with any request for a Letter of
Credit. A Letter of Credit shall be issued, amended, renewed or extended only if

37

 

(and upon issuance, amendment, renewal or extension of each Letter of Credit the applicable
Borrower shall be deemed to represent and warrant that), after giving effect to such issuance,
amendment, renewal or extension, the sum of the total Revolving Credit Exposures of all Lenders
shall not exceed the total Commitments. Unless the Issuing Bank has received written notice from
any Lender, the Administrative Agent or any Obligor, at least one Business Day prior to the
requested date of issuance, amendment, renewal or extension of the applicable Letter of Credit,
that one or more applicable conditions contained in Section 5.03 shall not then be
satisfied, then, subject to the terms and conditions hereof, the Issuing Bank shall, on the
requested date, issue, amend, renew or extend, as applicable, such Letter of Credit.

          (c) Expiration Date. Each Letter of Credit shall expire no later than the close of
business on the earlier of (i) the date that is three years after the date of issuance of such
Letter of Credit (or, in the case of any renewal or extension thereof, three years after such
renewal or extension) and (ii) the date that is fifteen (15) days prior to the Maturity Date then
in effect, provided that any Letter of Credit may provide for the automatic renewal thereof for
additional one-year periods (which shall in no event extend beyond the date referred to in clause
(ii) above).

          (d) Participations. By the issuance of a Letter of Credit (or an amendment to a
Letter of Credit increasing the amount thereof) and without any further action on the part of the
Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby
acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s
Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit.
In consideration and in furtherance of the foregoing, each Lender hereby absolutely and
unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank,
such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not
reimbursed by the Borrowers on the date due as provided in paragraph (e) of this
Section 3.01, or of any reimbursement payment required to be refunded to a Borrower for any
reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant
to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be
affected by any circumstance whatsoever, including any amendment, renewal or extension of any
Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the
Commitments, and that each such payment shall be made without any offset, abatement, withholding or
reduction whatsoever.

          (e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a
Letter of Credit, the Borrowers, jointly and severally, shall reimburse such LC Disbursement by
paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00
noon, New York City time, on the Business Day immediately following the date that such LC
Disbursement is made, if the Borrowers shall have received notice of such LC Disbursement on the
date that such LC Disbursement is made, or, if such notice has not been received by the Borrowers
on such date, then not later than 12:00 noon, New York City time, on the Business Day immediately
following the date that the Borrowers receive such notice; provided that, if such LC Disbursement
is not less than $1,000,000, the applicable Borrower may, subject to the conditions to borrowing
set forth herein, request in accordance with Section 2.02 or Section 2.03 that such
payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed,
the Borrowers’ obligation to make such payment shall be discharged and replaced by the resulting
ABR Borrowing. If the Borrowers fail

38

 

to make such payment when due, the Administrative Agent shall notify each Lender of the
applicable LC Disbursement, the payment then due from the Borrowers in respect thereof and such
Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender
shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the
Borrowers, in the same manner as provided in Section 2.03 with respect to Loans made by
such Lender (and Section 2.03 shall apply, mutatis mutandis, to the payment obligations of
the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so
received by it from the Lenders. Promptly following receipt by the Administrative Agent of any
payment from a Borrower pursuant to this paragraph, the Administrative Agent shall distribute such
payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this
paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their
interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the
Issuing Bank for any LC Disbursement (other than the funding of ABR Borrowings as contemplated
above) shall not constitute a Loan and shall not relieve any Borrower of its obligation to
reimburse such LC Disbursement.

          (f) Obligations Absolute. The Borrowers’ joint and several obligations to reimburse
LC Disbursements as provided in paragraph (e) of this Section shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this
Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity
or enforceability of any Letter of Credit or this Agreement, or any term or provision therein,
(ii) any draft or other document presented under a Letter of Credit proving to be forged,
fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any
respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft
or other document that does not comply with the terms of such Letter of Credit, excluding payments
by the Issuing Bank with respect to drafts or other documents that do not comply on their face with
the express terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever,
whether or not similar to any of the foregoing, that might, but for the provisions of this Section,
constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrowers’
obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any
of their Affiliates, shall have any liability or responsibility by reason of or in connection with
the issuance or transfer of any Letter of Credit or any payment or failure to make any payment
thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any
error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or
other communication under or relating to any Letter of Credit (including any document required to
make a drawing thereunder), any error in interpretation of technical terms or any consequence
arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not
be construed to excuse the Issuing Bank from liability to the Borrowers to the extent of any direct
damages (as opposed to consequential damages, claims in respect of which are hereby waived by the
Borrowers to the extent permitted by applicable law) suffered by a Borrower that are caused by the
Issuing Bank’s failure to exercise care when determining whether drafts and other documents
presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly
agree that, in the absence of gross negligence, willful misconduct or unlawful acts on the part of
the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank
shall be deemed to have exercised care in each such determination. In furtherance of the foregoing
and without limiting the generality thereof, the parties agree that, with respect to documents
presented which appear on their face to be in

39

 

substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole
discretion, either accept and make payment upon such documents without responsibility for further
investigation, regardless of any notice or information to the contrary, or refuse to accept and
make payment upon such documents if such documents are not in strict compliance with the terms of
such Letter of Credit.

          (g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt
thereof, examine all documents purporting to represent a demand for payment under a Letter of
Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower for whose
account the Letter of Credit was issued by telephone (confirmed by telecopy) of such demand for
payment and whether the Issuing Bank has made or shall make an LC Disbursement thereunder; provided
that any failure to give or delay in giving such notice shall not relieve any Borrower of its
obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC Disbursement.

          (h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then,
unless such LC Disbursement is reimbursed by a Borrower in full on the date such LC Disbursement is
made, the unpaid amount thereof shall bear interest, for each day from and including the date such
LC Disbursement is made to but excluding the date that such LC Disbursement is reimbursed, at the
rate per annum then applicable to ABR Borrowings; provided that, if the Borrowers fail to reimburse
such LC Disbursement when due pursuant to paragraph (e) of this Section 3.01, then
Section 2.09(d)(ii) shall apply. Interest accrued pursuant to this paragraph shall be for
the account of the Issuing Bank, except that interest accrued on and after the date of payment by
any Lender pursuant to paragraph (d) of this Section 3.01 to reimburse the Issuing
Bank shall be for the account of such Lender to the extent of such payment.

          (i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by
written agreement among WIL, the Administrative Agent, the replaced Issuing Bank and the successor
Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the
Issuing Bank. At the time any such replacement shall become effective, the Borrowers, jointly and
severally, shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant
to Section 2.08(b). From and after the effective date of any such replacement, (i) the
successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this
Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to
the term “Issuing Bank” shall be deemed to refer to such successor or to any previous
Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require.
After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party
hereto and shall continue to have all the rights and obligations of an Issuing Bank under this
Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not
be required to issue additional Letters of Credit.

          (j) Cash Collateralization. If any Event of Default shall occur and be continuing, on
the Business Day that the Borrowers receive notice from the Administrative Agent or the Required
Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure
representing greater than 51% of the total LC Exposure) demanding the deposit of cash collateral
pursuant to this paragraph, the Borrowers shall deposit in an account

40

 

with the Administrative Agent, in the name of the Administrative Agent and for the benefit of
the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid
interest thereon; provided that the joint and several obligation of the Borrowers to deposit such
cash collateral shall become effective immediately, and such deposit shall become immediately due
and payable, without demand or other notice of any kind, upon the occurrence of any Event of
Default with respect to a Borrower described in clauses (f) or (g) of
Section 9.01. If the Borrowers are required to provide cash collateralization pursuant to
Section 2.16, the Borrowers shall deposit in an account with the Administrative Agent, in
the name of the Administrative Agent and for the benefit of the Lenders, Dollars in the amount
required by Section 2.16, plus any accrued and unpaid interest thereon. Any such deposits
pursuant to this paragraph (j) shall be held by the Administrative Agent as collateral for
the payment and performance of the obligations of the Borrowers under this Agreement. The
Administrative Agent shall have exclusive dominion and control, as defined in the Uniform
Commercial Code of the State of New York, including the exclusive right of withdrawal, over such
account. The Administrative Agent shall have no obligation to pay interest on the investment of
such deposits, but the Administrative Agent shall invest such deposits in a manner consistent with
the Administrative Agent’s management of its own overnight cash investments, which investments
shall be made at the Borrowers’ risk and expense. Interest or profits, if any, on such investments
shall accumulate in such account. Moneys in such account shall be applied by the Administrative
Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and,
to the extent not so applied, shall be held for the satisfaction of the joint and several
reimbursement obligations of the Borrowers for the LC Exposure at such time or, if the maturity of
the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure representing
greater than 51% of the total LC Exposure), be applied to satisfy other obligations of the
Borrowers under this Agreement. If the Borrowers are required to provide an amount of cash
collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the
extent not applied as aforesaid) shall be returned to the Borrowers within three Business Days
after all Events of Default have been cured or waived.

ARTICLE IV

PAYMENTS; PRO RATA TREATMENT; TAXES

     SECTION 4.01. Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) Each Borrower shall
make each payment required to be made by it hereunder (whether of principal, interest, fees or
reimbursement of LC Disbursements, or of amounts payable under Sections 2.11, 2.12
or 4.02, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in
immediately available funds, without set-off or counterclaim. Any amounts received after such time
on any date may, in the discretion of the Administrative Agent, be deemed to have been received on
the next succeeding Business Day for purposes of calculating interest thereon. All such payments
shall be made to the Administrative Agent at its offices at 60 Wall Street, New York, New York
10005, except payments to be made directly to the Issuing Bank as expressly provided herein and
except that payments pursuant to Sections 2.11, 2.12, 4.02 and
12.04 shall be made directly to the Persons entitled thereto. The Administrative Agent
shall distribute any such payments received by it for the account of any
other Person to the appropriate recipient promptly following receipt thereof. If any payment
hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended
to the next succeeding Business Day, and, in the case of any payment accruing interest, interest
thereon

41

 

shall be payable for the period of such extension. All payments hereunder of principal or
interest in respect of any Loan (or of any breakage indemnity in respect of any Loan) shall be made
in the Currency of such Loan; all other payments hereunder and under each other Loan Document shall
be made in Dollars. Any payment required to be made by the Administrative Agent hereunder shall be
deemed to have been made by the time required if the Administrative Agent shall, at or before such
time, have taken the necessary steps to make such payment in accordance with the regulations or
operating procedures of the clearing or settlement system used by the Administrative Agent to make
such payment. Any amount payable by the Administrative Agent to one or more Lenders in the national
currency of a member state of the European Union that has adopted the Euro as its lawful currency
shall be paid in Euro.

          (b) If at any time insufficient funds are received by and available to the Administrative
Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then
due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due
hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest
and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed
LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with
the amounts of principal and unreimbursed LC Disbursements then due to such parties.

          (c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise,
obtain payment in respect of any principal of or interest on any of its Loans or participations in
LC Disbursements resulting in such Lender receiving payment of a greater proportion of the
aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon
than the proportion received by any other Lender, then the Lender receiving such greater proportion
shall purchase (for cash at face value) participations in the Loans and participations in LC
Disbursements of other Lenders to the extent necessary so that the benefit of all such payments
shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and
accrued interest on their respective Loans and participations in LC Disbursements; provided that
(i) if any such participations are purchased and all or any portion of the payment giving rise
thereto is recovered, such participations shall be rescinded and the purchase price restored to the
extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be
construed to apply to any payment made by a Borrower pursuant to and in accordance with the express
terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of
or sale of a participation in any of its Loans or participations in LC Disbursements to any
assignee or participant, other than to a Borrower or any Subsidiary or Affiliate thereof (as to
which the provisions of this paragraph shall apply). Each Borrower consents to the foregoing and
agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a
participation pursuant to the foregoing arrangements may exercise against such Borrower rights of
set-off and counterclaim with respect to such participation as fully as if such Lender were a
direct creditor of such Borrower in the amount of such participation.

          (d) Unless the Administrative Agent shall have received notice from a Borrower prior to the
date on which any payment is due to the Administrative Agent for the account of the Lenders or the
Issuing Bank hereunder that such Borrower shall not make such payment, the Administrative Agent may
assume that such Borrower has made such payment on

42

 

such date in accordance herewith and may, in
reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be,
the amount due. In such event, if a Borrower has not in fact made such payment, then each of the
Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative
Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest
thereon, for each day from and including the date such amount is distributed to it to but excluding
the date of payment to the Administrative Agent, at (i) the greater of the Federal Funds Effective
Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on
interbank compensation (in the case of an amount denominated in Dollars) and (ii) the rate
reasonably determined by the Administrative Agent to be the cost to it of funding such amount (in
the case of an amount denominated in any Optional Currency).

          (e) If any Lender shall fail to make any payment required to be made by it pursuant to
Section 3.01(d), 3.01(e), 2.03(b) or 4.01(d), then the
Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply
any amounts thereafter received by the Administrative Agent for the account of such Lender to
satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are
fully paid.

     SECTION 4.02. Taxes.

          (a) Any and all payments by or on account of any obligation of the Borrowers hereunder shall
be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided
that if any Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such
payments, then (i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable under this Section)
the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to
the sum it would have received had no such deductions been made, (ii) such Borrower shall make such
deductions and (iii) such Borrower shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law.

          (b) The Borrowers, jointly and severally, shall indemnify the Administrative Agent, each
Lender and the Issuing Bank, within 20 days after written demand therefor, for the full amount of
any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing
Bank, as the case may be, on or with respect to any payment by or on account of any obligation of a
Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) and any penalties, interest and reasonable
expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other
Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A
certificate as to the amount of such payment or liability delivered to the Borrowers by a Lender or
the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the
Issuing Bank, shall be presumed correct absent manifest error.

          (c) Any Lender that is entitled to an exemption from or reduction of withholding tax under the
law of the jurisdiction in which a Borrower is located or treated as located for income Tax
purposes, or any treaty to which any such jurisdiction is a party, with respect to payments under
this Agreement shall deliver to such Borrower (with a copy to the Administrative Agent), at the
time or times prescribed by applicable law, such properly

43

 

completed and executed documentation
prescribed by applicable law or reasonably requested by such Borrower as shall permit such payments
to be made without withholding or at a reduced rate.

          (d) If the Administrative Agent or a Lender determines, in its sole discretion, that it has
received a refund of any Taxes or Other Taxes paid by a Borrower or with respect to which a
Borrower has paid additional amounts pursuant to this Section 4.02, it shall pay over such
refund to such Borrower (but only to the extent of indemnity payments made, or additional amounts
paid, by such Borrower under this Section 4.02 with respect to the Taxes or Other Taxes
giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such
Lender and without interest (other than any interest paid by the relevant Governmental Authority
with respect to such refund); provided that each Borrower, upon the request of the Administrative
Agent or such Lender, agrees to repay promptly the amount paid over to such Borrower (plus any
penalties, interest or other charges imposed by the relevant Governmental Authority with respect to
such amount) to the Administrative Agent or such Lender in the event the Administrative Agent or
such Lender is required to repay such refund to such Governmental Authority. This Section shall not
be construed to require the Administrative Agent or any Lender to make available its Tax returns
(or any other information relating to its Taxes which it deems confidential) to any Borrower or any
other Person.

          (e) Without limiting the generality of the foregoing, each Foreign Lender shall deliver to
each Borrower and the Administrative Agent on the Effective Date or upon the effectiveness of any
Assignment and Assumption by which it becomes a party to this Agreement (i) two duly completed
copies of United States Internal Revenue Service Form W-8ECI, W-8BEN, W-8EXP or W-8IMY or other
applicable governmental form, as the case may be, certifying in each case that such Lender is
entitled to receive payments under this Agreement and the Notes payable to it without deduction or
withholding of any United States federal income Taxes, as if each Borrower were incorporated under
the laws of the United States or a State thereof, and (ii) any other governmental forms which are
necessary or required under an applicable Tax treaty or otherwise by law to eliminate any
withholding Tax or which have been reasonably requested by the Borrowers. Each Lender which
delivers to the Borrowers and the Administrative Agent a Form W-8ECI, W-8BEN, W-8EXP or W-8IMY or
other applicable governmental form pursuant to the preceding sentence further undertakes to deliver
to the Borrowers and the Administrative Agent two further copies of such form on or before the date
that any such form expires (currently, three successive calendar years for Form W-8BEN or Form
W-8ECI) or becomes obsolete or after the occurrence of any event requiring a change in the most
recent form so delivered by it, and such amendments thereto or extensions or renewals thereof as
may reasonably be requested by a Borrower and the Administrative Agent, in each case certifying
that such Lender is entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income Taxes, unless an event (including any change in
treaty, law or regulation) has occurred prior to the date on which any such delivery would
otherwise be required which renders all such forms inapplicable or which would prevent
such Lender from duly completing and delivering any such form with respect to it and such
Lender advises the Borrowers and the Administrative Agent that it is not capable of receiving
payments without any deduction or withholding of United States federal income Taxes and in any such
event, each Borrower shall withhold Taxes at the rate and in the manner required by the laws of the
United States with respect to payments made to such a Lender and shall be required

44

 

to pay any
additional amounts or indemnify such a Lender pursuant to this Section 4.02 with respect to
such withheld Taxes.

          (f) The Borrowers, jointly and severally, will remit to the appropriate Governmental
Authority, prior to delinquency, all Indemnified Taxes and Other Taxes payable in respect of any
payment. Within 30 days after the date of any payment of Indemnified Taxes or Other Taxes, the
applicable Borrower will furnish to the Administrative Agent the original or a certified copy of a
receipt evidencing payment of such Indemnified Taxes or Other Taxes or such other evidence thereof
as may be reasonably satisfactory to the Administrative Agent.

     SECTION 4.03. Mitigation Obligations; Replacement of Lenders; Replacement of Issuing Bank.

          (a) If any Lender requests compensation under Section 2.11, or if a Borrower is
required to pay any additional amount to any Lender or any Governmental Authority for the account
of any Lender pursuant to Section 4.02, then such Lender shall use reasonable efforts to
designate a different lending office for funding or booking its Loans hereunder or to assign its
rights and obligations hereunder to another of its offices, branches or affiliates, if, in the
judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts
payable pursuant to Section 2.11 or 4.02, as the case may be, in the future and
(ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be
disadvantageous to such Lender. The Borrowers hereby, jointly and severally, agree to pay all
reasonable costs and expenses incurred by any Lender in connection with any such designation or
assignment.

          (b) If (i) any Lender requests compensation under Section 2.11, or (ii) a Borrower is
required to pay any additional amount to any Lender or any Governmental Authority for the account
of any Lender pursuant to Section 4.02, or (iii) any Lender defaults in its obligation to
fund Loans hereunder, or (iv) any Lender fails to provide its consent to a Redomestication under
the laws of a jurisdiction (other than the United Kingdom or The Kingdom of the Netherlands)
outside of the United States, or (v) any Lender fails to agree to extend the Maturity Date pursuant
to Section 2.14 if the Required Lenders have agreed to do so, then WIL 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 Section 12.05), all its interests, rights and obligations under this Agreement to an
assignee that shall assume such obligations (which assignee may be another Lender, if a Lender
accepts such assignment); provided that (1) WIL shall have received the prior written consent of
the Issuing Bank and, if such assignee is not already a Lender
hereunder, the Administrative Agent, which consent of the Issuing Bank and the Administrative
Agent (if applicable) shall not be unreasonably withheld, conditioned or delayed, (2) such Lender
shall have received payment of an amount equal to the outstanding principal of its Loans and
participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts
payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued
interest and fees) or the applicable Borrower (in the case of all other amounts) and (3) in the
case of any such assignment resulting from a claim for compensation under Section 2.11 or
payments required to be made pursuant to Section 4.02, such assignment shall result in a
reduction in such compensation or payments. A Lender shall not be required to make

45

 

any such
assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise,
the circumstances entitling WIL to require such assignment and delegation cease to apply and such
Lender neither received nor continued to claim any such compensation or payment.

          (c) If the Issuing Bank refuses to approve any Commitment Increase under Section 2.15,
then WIL may, at its sole expense and effort, upon notice to the Issuing Bank and the
Administrative Agent, replace the Issuing Bank; provided that (i) if the successor Issuing Bank is
not already a Lender hereunder, WIL shall have received the prior written consent of the
Administrative Agent, which consent shall not be unreasonably withheld, conditioned or delayed and
(ii) if there are any Letters of Credit outstanding at the time of any such replacement, such
replacement shall not become effective until each such outstanding Letter of Credit (A) shall have
expired, (B) shall have been cancelled, (C) shall have been replaced with one or more Letters of
Credit issued by the replacement Issuing Bank on the effective date of such replacement or
(D) shall be supported by a “back-to-back” Letter of Credit issued by the replacement Issuing Bank
on the effective date of such replacement. The Administrative Agent shall notify the Lenders of
any such replacement of the Issuing Bank pursuant to this Section 4.03(c). At the time any
such replacement shall become effective, the Borrowers, jointly and severally, shall pay all unpaid
fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.08(b).
From and after the effective date of any such replacement, (x) the successor Issuing Bank shall
have all the rights and obligations of the Issuing Bank under this Agreement with respect to
Letters of Credit to be issued thereafter and (y) references herein to the term “Issuing
Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such
successor and all previous Issuing Banks, as the context shall require. After the replacement of
an Issuing Bank under this Section 4.03(c), to the extent any Letters of Credit issued by
the replaced Issuing Bank remain outstanding after such replacement, the replaced Issuing Bank
shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing
Bank under this Agreement with respect to such Letters of Credit, but shall not be required to
issue additional Letters of Credit.

ARTICLE VI

REPRESENTATIONS AND WARRANTIES

     To induce the Lenders to enter into this Agreement and to make the Loans and issue or
participate in Letters of Credit, each Obligor represents and warrants as to itself, and WIL
represents and warrants as to the other Obligors (such representations and warranties to survive
any investigation and the making of the Loans), to the Lenders, the Issuing Bank and the
Administrative Agent as follows:

     SECTION 6.01. Organization and Qualification. Each Obligor and each Material Subsidiary (a) is a
company, corporation, partnership, or entity having limited liability that is duly organized or
formed, validly existing and in good standing under the laws of the jurisdiction of its
incorporation or formation, (b) has the corporate, partnership or other power and authority to own
its property and to carry on its business as now conducted and (c) is duly qualified as a foreign
corporation or other foreign entity to do business and is in good standing in every jurisdiction in
which the failure to be so qualified would, together with all such other failures of the Obligors
and their Subsidiaries, have a Material Adverse Effect.

     SECTION 6.02. Authorization, Validity, Etc. Each Obligor has the corporate or other power and authority
to execute, deliver and perform its obligations hereunder and under the other Loan Documents to
which it is a party and to obtain the Loans and request Letters of Credit, and all such action has
been duly authorized by all necessary corporate, partnership or other proceedings on its part or on
its behalf. This Agreement has been duly and validly executed and delivered by or on behalf of
each Obligor and constitutes valid and legally binding agreements of such Obligor enforceable
against such Obligor in accordance with the terms hereof, and the Notes and the other Loan
Documents to which such Obligor is a party, when duly executed and delivered by or on behalf of
such Obligor, shall constitute valid and legally binding obligations of such Obligor enforceable in
accordance with the respective terms thereof and of this Agreement, except, in each case (a) as may
be limited by bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or
other similar laws relating to or affecting the enforcement of creditors’ rights generally, and by
general principles of equity which may limit the right to obtain equitable remedies (regardless of
whether such enforceability is a proceeding in equity or at law) and (b) as to the enforceability
of provisions for indemnification and the limitations thereon arising as a matter of law or public
policy.

     SECTION 6.03. Governmental Consents, Etc. No authorization, consent, approval, license or exemption of
or filing or registration with any Governmental Authority, is necessary for the valid execution,
delivery or performance by any Obligor of any Loan Document to which it is a party, except those
that have been obtained and are in full force and effect and such matters relating to performance
as would ordinarily be done in the ordinary course of business after the Effective Date.

     SECTION 6.04. No Breach or Violation of Law or Agreements. Neither the execution, delivery and
performance by any Obligor of the Loan Documents to which it is a party, nor compliance with the
terms and provisions thereof, nor the extensions of credit contemplated by the Loan Documents,
(a) shall breach or violate any applicable Requirement of Law, (b) shall result in any breach or
violation of, or constitute a default under, or result in the creation or

49

 

imposition of (or the
obligation to create or impose) any Lien upon any of its property or assets pursuant to the terms
of, any indenture, agreement or other instrument to which it or any of its consolidated
Subsidiaries is party or by which any property or asset of it or any of its consolidated
Subsidiaries is bound or to which it is subject, except for breaches, violations and defaults under
clauses (a) and (b) that collectively for the Obligors shall not have a Material
Adverse Effect or (c) shall violate any provision of the organizational documents or by-laws of any
Obligor.

     SECTION 6.05. Litigation. As of the Effective Date, except for actions, suits or proceedings described
in the filings made by WIL with the Securities and Exchange Commission pursuant to the Exchange
Act, (a) there are no actions, suits or proceedings pending or, to the best knowledge of WIL,
threatened against any Obligor or against any of their respective properties or assets that are
reasonably likely to have (individually or collectively) a Material Adverse Effect and (b) to the
best knowledge of WIL, there are no actions, suits or proceedings pending or threatened that
purport to affect or pertain to the Loan Documents or any transactions contemplated thereby.

     SECTION 6.06. Information; Financial Statements. All information heretofore furnished by the Obligors to
the Administrative Agent or any Lender in connection with this Agreement, as an amendment and
restatement of the Existing Credit Agreement, when considered together with the disclosures made
herein, in the other Loan Documents and in the filings made by any Obligor with the Securities and
Exchange Commission pursuant to the Exchange Act, did not as of the date thereof and shall not as
of the Effective Date, when read together and taken as a whole, contain any untrue statement of a
material fact or omit to state a material fact necessary in order to make the statements contained
therein not misleading in any material respect. As of the Effective Date, there has been no
material adverse change since December 31, 2007 in the financial condition, business or operations
of WIL and its Subsidiaries taken as a whole which could reasonably be expected to have a Material
Adverse Effect.

     SECTION 6.07. Investment Company Act; Sanctions; Etc. (a) No Obligor nor any of its Subsidiaries is, or
is regulated as, an “investment company,” as such term is defined in the Investment Company Act of
1940 (as adopted in the United States), as amended.

     (b) Neither Borrower nor any of its Subsidiaries (i) is a person on the list of Specially
Designated Nationals and Blocked Persons or subject to the limitations or prohibitions under any
other program administered or enforced by U.S. Department of Treasury’s Office of Foreign Assets
Control (“OFAC”) (a “Prohibited Person”), or (ii) will knowingly use any proceeds
of the Loans, directly or indirectly, (a) to support activities in any country subject to a
comprehensive sanctions program administered by OFAC, where such activities would be in violation
of the sanctions program, (b) to conduct business with a Prohibited Person or any individual or
entity controlled by a Prohibited Person, or (c) to facilitate terrorism, money laundering,
narcotics trafficking, nuclear proliferation, or other illegal activity.

     (c) No part of the proceeds of the Loans will be used, directly or indirectly, for any
payments to any governmental official or employee, political party, official of a political party,
candidate for political office, or anyone else acting in an official capacity, or any close
relative of such person in order to obtain, retain, or direct business or obtain any improper

expected to have a Material Adverse Effect.

          (c) No Obligor and its ERISA Affiliates have incurred or reasonably expect to incur withdrawal

(including estimated taxes
shown on such returns, statements and reports) which are shown to be due pursuant to such returns,

59

 

event, the Administrative Agent may, and at the request of the Required
Lenders shall, by notice to the Borrowers, take either or both of the following actions, at the

(general or special, time or demand, provisional or final but excluding the funds held in accounts
clearly designated as escrow or trust accounts held by any Obligor for the benefit of Persons which
are not Affiliates of any Obligor), whether or not such setoff results in any loss of interest or
other penalty, and including all certificates of deposit, at any time held and other obligations at
any time owing by such Lender to or for the credit or the account of any Obligor against any and
all of the Obligations irrespective of whether or not such Lender or the Administrative Agent shall
have made any demand under this Agreement, the Notes or any other Loan Document. Should the right
of any Lender to realize funds in any manner set forth above be challenged and any application of
such funds be reversed, whether by court order or otherwise, the Lenders shall make restitution or
refund to the applicable Obligor, as the case may be, pro rata in accordance with their
Commitments. Each Lender agrees to promptly notify the applicable Obligor and the Administrative
Agent after any such setoff and application, provided that the failure to give such notice shall
not affect the validity of such setoff and application. The rights of the Administrative Agent and
the Lenders under this Section are in addition to other rights and remedies (including other rights
of setoff) which the Administrative Agent or the Lenders may have. This Section is subject to the
terms and provisions of Section 4.01(a).

     SECTION 9.03. Other Remedies. No remedy conferred herein or in any of the other Loan Documents is to be
exclusive of any other remedy, and each and every remedy contained herein or in any other Loan
Document shall be cumulative and shall be in addition to every other remedy given hereunder and
under the other Loan Documents now or hereafter existing at law or in equity or by statute or
otherwise.

          (a) So long as an Event of Default of which the Administrative Agent shall have given notice
to the Lenders shall continue, all moneys received by the Administrative Agent (i) from any Obligor
under the Loan Documents shall, except as otherwise required by law, be distributed by the
Administrative Agent on the dates selected by the Administrative Agent as follows:

first, to payment of the unreimbursed expenses for which the Administrative
Agent or any Lender is to be reimbursed pursuant to Section 12.03 and to any
unpaid fees owing to the Administrative Agent;

third, to the ratable payment of unpaid principal of the Loans;

fourth, to the ratable payment of all other amounts payable by the Obligors
hereunder;

fifth, to secure the repayment and discharge of the outstanding amount of
all LC Exposure;

sixth, to the ratable payment of all other Obligations, until all
Obligations shall have been paid in full; and

finally, to payment to the Obligors, or their respective successors or
assigns, or as a court of competent jurisdiction may direct, of any surplus then
remaining from such proceeds.

          (b) The term “unpaid” as used in this Section 9.04 shall mean all Obligations
outstanding as of any such distribution date as to which prior distributions have not been made,
after giving effect to any adjustments which are made pursuant to Section 9.02 of which the
Administrative Agent shall have been notified. For purposes of the foregoing, reimbursement
obligations with respect to the LC Exposure on outstanding Letters of Credit shall be deemed “paid”
for purposes of this Section 9.04 when amounts sufficient to secure such reimbursement
obligations have been delivered to the Administrative Agent.

ARTICLE X

ADMINISTRATIVE AGENT

     Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent
as its agent and authorizes the Administrative Agent to take such actions on its behalf and to
exercise such powers as are delegated to the Administrative Agent by the terms hereof, together
with such actions and powers as are reasonably incidental thereto.

     The bank serving as the Administrative Agent hereunder shall have the same rights and powers
in its capacity as a Lender as any other Lender and may exercise the same as though it were not the
Administrative Agent, and such bank and its Affiliates may accept deposits from,

61

 

lend money to and
generally engage in any kind of business with any Obligor or any Subsidiary or other Affiliate
thereof as if it were not the Administrative Agent hereunder.

     The Administrative Agent shall not have any duties or obligations except those expressly set
forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall
not be subject to any fiduciary or other implied duties, regardless of whether a Default or an
Event of Default has occurred and is continuing, (b) the Administrative Agent shall not have any
duty to take any discretionary action or exercise any discretionary powers, except discretionary
rights and powers expressly contemplated hereby that the Administrative Agent is required to
exercise in writing as directed by the Required Lenders (or such other number or percentage of the
Lenders as shall be necessary under the circumstances as provided in Section 12.01), and
(c) except as expressly set forth herein, the Administrative Agent shall not have any duty to
disclose, and shall not be liable for the failure to disclose, any information relating to any of
the Obligors or any of their Subsidiaries that is communicated to or obtained by the bank serving
as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall
not be liable for any action taken or not taken by it with the consent or at the request of the
Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 12.01) or in the absence of its own gross negligence,
willful misconduct or unlawful acts. The Administrative Agent shall be deemed not to have
knowledge of any Default or Event of Default unless and until written notice thereof is given to
the Administrative Agent by a Borrower or a Lender, and the Administrative Agent shall not be
responsible for or have any duty to ascertain or inquire into (v) any statement, warranty or
representation made in or in connection with this Agreement, (w) the contents of any certificate,
report or other document delivered hereunder or in connection herewith, (x) the performance or
observance of any of the covenants, agreements or other terms or conditions set forth herein,
(y) the validity, enforceability, effectiveness or genuineness of this Agreement or any other
agreement, instrument or document, or (z) the satisfaction of any condition set forth in
Article V or elsewhere herein, other than to confirm receipt of items expressly required to
be delivered to the Administrative Agent.

     The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for
relying upon, any notice, request, certificate, consent, statement, instrument, document or other
writing believed by it to be genuine and to have been signed or sent by the proper Person. The
Administrative Agent also may rely upon any statement made to it orally or by telephone and
believed by it to be made by the proper Person, and shall not incur any liability for relying
thereon. The Administrative Agent may consult with legal counsel (who may be counsel for any
Borrower), independent accountants and other experts selected by it, and shall not be liable for
any action taken or not taken by it in accordance with the advice of any such counsel, accountants
or experts.

     The Administrative Agent may perform any and all its duties and exercise its rights and powers
by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative
Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers
through their respective Related Parties. The exculpatory provisions of the preceding paragraphs
shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any
such sub-agent, and shall apply to their respective activities in

62

 

connection with the syndication
of the credit facilities provided for herein as well as activities as Administrative Agent.

     Subject to the appointment and acceptance of a successor Administrative Agent as provided in
this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the
Issuing Bank and WIL. Upon any such resignation, the Required Lenders shall have the right, in
consultation with WIL, to appoint a successor. If no successor shall have been so appointed by the
Required Lenders and shall have accepted such appointment within 30 days after the retiring
Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may,
on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall
be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the
acceptance of its appointment as Administrative Agent hereunder by a successor, such successor
shall succeed to and become vested with all the rights, powers, privileges and duties of the
retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its
duties and obligations hereunder. The fees payable by the Borrowers to a successor Administrative
Agent shall be the same as those payable to its predecessor unless otherwise agreed between the
Borrowers and such successor. After the Administrative Agent’s resignation hereunder, the
provisions of this Article and Sections 12.03 and 12.04 shall continue in effect
for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related
Parties in respect of any actions taken or omitted to be taken by any of them while it was acting
as Administrative Agent.

     Each Lender acknowledges that it has, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each
Lender also acknowledges that it shall, independently and without reliance upon the Administrative
Agent or any other Lender and based on such documents and information as it shall from time to time
deem appropriate, continue to make its own decisions in taking or not taking action under or based
upon this Agreement, any related agreement or any document furnished hereunder or thereunder.

     Notwithstanding anything to the contrary contained herein, neither the Syndication Agent,
Documentation Agent, the Bookrunner nor the Lead Arranger listed on the cover page hereof shall
have any powers, duties or responsibilities under this Agreement or any of the other Loan
Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender or the
Issuing Bank hereunder.

ARTICLE XI

GUARANTY

     SECTION 11.01. Guaranty.

          (a) In consideration of, and in order to induce the Lenders to make Loans to, and the Issuing
Bank to issue Letters of Credit for the account of, the Borrowers (including, without limitation,
any additional Persons becoming Borrowers hereunder after the date hereof), WII hereby absolutely,
unconditionally and irrevocably guarantees in favor of all of the Lenders and the Issuing Bank, the
punctual payment and performance when due, whether at stated

63

 

maturity, by acceleration or
otherwise, of the Obligations and all covenants of the Borrowers, now or hereafter existing under
this Agreement and the other Loan Documents to which any Borrower is a party, whether for
principal, LC Exposure, interest (including interest accruing or becoming owing both prior to and
subsequent to the commencement of any proceeding against or with respect to any Borrower under any
applicable bankruptcy or insolvency law (including the Bankruptcy Code), fees, commissions,
expenses (including reasonable attorneys’ fees and expenses)), indemnities, or otherwise (all such
obligations being, as applicable, the “Guaranteed Obligations”). WII agrees to pay any and
all expenses incurred by each Lender and the Administrative Agent in enforcing this Guaranty
against WII.

          (b) This Guaranty is an absolute, unconditional, present and continuing guaranty of payment
and not of collection and is in no way conditioned upon any attempt to collect from any Borrower or
any other action, occurrence or circumstance whatsoever.

          (c) The obligations of WII under this Guaranty shall be limited to an aggregate amount equal
to the largest amount that would not render this Guaranty subject to avoidance under Section 548 of
the Bankruptcy Code or any comparable provisions of applicable law.

     SECTION 11.02. Continuing Guaranty.

          (a) WII guarantees that the Guaranteed Obligations shall be paid strictly in accordance with
the terms of this Agreement and the other Loan Documents; provided that if payment in respect of
any Guaranteed Obligations shall be due in a currency other than Dollars and if, by reason of any
legal prohibition, disruption of currency or foreign exchange markets, war or civil disturbance or
other event, payment of such Guaranteed Obligations in such currency shall be impossible or, in the
reasonable judgment of the Administrative Agent or any Lender, not consistent with the protection
of its rights or interests, then, at the election of the Administrative Agent or such Lender, WII
shall make payment of the Dollar Equivalent of such Guaranteed Obligations and shall indemnify the
Administrative Agent or such Lender against any losses or expenses (including losses or expenses
resulting from fluctuations in exchange rates) that it shall sustain as a result of such
alternative payment. WII agrees that, to the maximum extent permitted by applicable law, the
Guaranteed Obligations and Loan Documents to which any Borrower is a party may be extended or
renewed, and indebtedness thereunder repaid and reborrowed in whole or in part, without notice to
or assent by WII, and that WII shall remain bound upon this Guaranty notwithstanding any extension,
renewal or other alteration of any of the Guaranteed Obligations or such Loan Documents or any
repayment and reborrowing of Loans to the Borrowers. The obligations of WII under this Guaranty
are absolute and unconditional irrespective of the value, genuineness, validity, regularity or
enforceability of the obligations of the Borrowers under this Agreement or any other Loan Document
or any substitution, release or exchange of any other guarantee of or security for the Obligations.
To the maximum extent permitted by applicable law, except as otherwise expressly provided in this
Agreement or any other Loan Document to which WII is a party, the obligations of WII under this
Guaranty shall be absolute, unconditional and irrevocable, and shall be performed strictly in
accordance with the terms hereof under any circumstances whatsoever, including:

64

 

     (i) any modification, amendment, supplement, renewal, extension for any period,
increase, decrease, alteration or rearrangement of all or any part of the Guaranteed
Obligations, or of this Agreement or any other Loan Document executed in connection
herewith, or any contract or understanding among the Borrowers, the Administrative Agent,
the Issuing Bank and/or the Lenders, or any other Person, pertaining to the Guaranteed
Obligations;

     (ii) any adjustment, indulgence, forbearance or compromise that might be granted or
given by the Lenders to WII, any Borrower or any other Person liable on the Guaranteed
Obligations;

     (iii) the insolvency, bankruptcy, arrangement, adjustment, composition, liquidation,
disability, dissolution or lack of power of WII, any Borrower or any other Person at any
time liable for the payment of all or part of the Guaranteed Obligations; or any dissolution
or winding up of WII or any Borrower, or any sale, lease or transfer of any or all of the
assets of WII or any Borrower, or any changes in the shareholders of WII or any Borrower, or
any reorganization of WII or any Borrower;

     (iv) the invalidity, illegality or unenforceability of all or any part of the
Guaranteed Obligations, or any document or agreement executed in connection with the
Guaranteed Obligations, for any reason whatsoever, including the fact that (A) the
Guaranteed Obligations, or any part thereof, exceed the amount permitted by law, (B) the act
of creating the Guaranteed Obligations, or any part thereof is ultra vires, (C) the officers
or representatives executing the documents or otherwise creating the Guaranteed Obligations
acted in excess of their authority, (D) the Guaranteed Obligations or any part thereof
violate applicable usury laws, (E) WII or any Borrower has valid defenses, claims, and
offsets (whether at law or in equity, by agreement or by statute) which render the
Guaranteed Obligations wholly or partially uncollectible from WII or any Borrower, (F) the
creation, performance, or repayment of the Guaranteed Obligations (or execution, delivery
and performance of any document or instrument representing any part of the Guaranteed
Obligations or executed in connection with any of the Guaranteed Obligations, or given to
secure the repayment of the Guaranteed Obligations) is illegal, uncollectible, legally
impossible or unenforceable, or (G) this Agreement, any other Loan Document, or any other
document or instrument pertaining to any of the Guaranteed Obligations has been forged or
otherwise is irregular or not genuine or authentic;

     (v) any full or partial release of the liability of WII or any Borrower on the
Guaranteed Obligations or any part thereof, or any other Person now or hereafter liable,
whether directly or indirectly, jointly, severally, or jointly and severally, to pay,
perform, guarantee, or assure the payment of the Guaranteed Obligations or any part thereof;
it being recognized, acknowledged, and agreed by WII that WII may be required to pay the
Guaranteed Obligations in full without assistance or support of any other Person, and that
WII has not been induced to enter into this Guaranty on the basis of a contemplation,
belief, understanding or agreement that any other Person shall be liable to perform the
Guaranteed Obligations or that the Administrative Agent or any Lender shall look to any
other Person to perform the Guaranteed Obligations;

65

 

     (vi) the taking or accepting of any other security, collateral or guaranty, or other
assurance of payment, for all or any part of the Guaranteed Obligations;

     (vii) any release, surrender, exchange, subordination, deterioration, waste, loss or
impairment of any collateral, property or security, at any time existing in connection with,
or assuring or securing payment of, all or any part of the Guaranteed Obligations;

     (viii) the failure of the Administrative Agent, the Lenders, the Issuing Bank or any
other Person to exercise diligence or reasonable care in the preservation, protection,
enforcement, sale or other handling or treatment of all or any part of such collateral,
property or security;

     (ix) the fact that any collateral, security or Lien contemplated or intended to be
given, created or granted as security for the repayment of the Guaranteed Obligations shall
not be properly perfected or created, or shall prove to be unenforceable or subordinate to
any other Lien; it being recognized and agreed by WII that WII is not entering into this
Guaranty in reliance on, or in contemplation of the benefits of, the
validity, enforceability, collectibility or value of any of the collateral for the
Guaranteed Obligations;

     (x) any payment by any Borrower or WII to the Administrative Agent or any Lender is
held to constitute a preference under bankruptcy or insolvency laws, or for any other reason
either the Administrative Agent or any Lender is required to refund such payment or pay such
amount to any Borrower, WII or any other Person; or

     (xi) any other action taken or omitted to be taken with respect to this Agreement, any
other Loan Document, the Guaranteed Obligations, or the security and collateral therefor,
whether or not such action or omission prejudices WII or increases the likelihood that WII
shall be required to pay the Guaranteed Obligations pursuant to the terms hereof;

it being the unambiguous and unequivocal intention of WII that WII shall be obligated to pay the
Guaranteed Obligations when due, notwithstanding any occurrence, circumstance, event, action, or
omission whatsoever, whether contemplated or uncontemplated, and whether or not otherwise or
particularly described herein, except for the full and final payment and satisfaction of the
Guaranteed Obligations after the termination of all of the Commitments.

          (b) WII further agrees that, to the fullest extent permitted by law, as between WII, or the
one hand, and the Lenders and the Administrative Agent, on the other hand, (i) the maturity of the
Obligations may be accelerated as provided in Section 9.01 for the purposes of this
Guaranty, notwithstanding any stay, injunction or other prohibition preventing the acceleration of
the Obligations as against any Borrower and (ii) in the event of any purported acceleration
(whether by declaration or automatic) of the Obligations as provided in Section 9.01, the
Obligations (whether or not due and payable) shall forthwith become due and payable by WII for the
purpose of this Guaranty.

     SECTION 11.03. Effect of Debtor Relief Laws. If after receipt of any payment of, or
proceeds of any security applied (or intended to be applied) to the payment of all or any part of

66

 

the Guaranteed Obligations, the Administrative Agent or any Lender is for any reason compelled to
surrender or voluntarily surrenders, such payment or proceeds to any Person (a) because such
payment or application of proceeds is or may be avoided, invalidated, declared fraudulent, set
aside, determined to be void or voidable as a preference, fraudulent conveyance, fraudulent
transfer, impermissible set-off or a diversion of trust funds or (b) for any other reason,
including (i) any judgment, decree or order of any court or administrative body having jurisdiction
over the Administrative Agent, the Issuing Bank, any Lender or any of their respective properties
or (ii) any settlement or compromise of any such claim effected by the Administrative Agent or any
Lender with any such claimant (including any Borrower), then the Guaranteed Obligations or any part
thereof intended to be satisfied shall be reinstated and continue, and this Guaranty shall continue
in full force as if such payment or proceeds had not been received, notwithstanding any revocation
thereof or the cancellation of any instrument evidencing any of the Guaranteed Obligations or
otherwise; and WII shall be liable to pay the Administrative Agent, the Issuing Bank and the
Lenders, and hereby does indemnify the Administrative Agent, the Issuing Bank and the Lenders and
hold them harmless
for the amount of such payment or proceeds so surrendered and all reasonable expenses (including
reasonable attorneys’ fees, court costs and expenses attributable thereto) incurred by the
Administrative Agent, the Issuing Bank or any such Lender in the defense of any claim made against
it that any payment or proceeds received by the Administrative Agent, the Issuing Bank or any such
Lender in respect of all or part of the Guaranteed Obligations must be surrendered. The provisions
of this paragraph shall survive the termination of this Guaranty and any satisfaction and discharge
of the Borrowers by virtue of any payment, court order, or any law.

     SECTION 11.04. Waiver. WII hereby waives promptness, diligence, notice of acceptance and
any other notice with respect to any of the Guaranteed Obligations and this Guaranty and waives
presentment, demand for payment, notice of intent to accelerate, notice of dishonor or nonpayment
and any requirement that the Administrative Agent, the Issuing Bank or any Lender institute suit,
collection proceedings or take any other action to collect any of the Guaranteed Obligations,
including any requirement that the Administrative Agent, the Issuing Bank or any Lender protect,
secure, perfect or insure any Lien against any property subject thereto or exhaust any right or
take any action against any Borrower or any other Person or any collateral (it being the intention
of the Administrative Agent, the Issuing Bank, the Lenders, and WII that this Guaranty is to be a
guaranty of payment and not of collection). It shall not be necessary for the Administrative
Agent, the Issuing Bank or any Lender, in order to enforce any payment by WII hereunder, to
institute suit or exhaust its rights and remedies against WII, any Borrower or any other Person,
including others liable to pay the Guaranteed Obligations, or to enforce its rights against any
security ever given to secure payment thereof. WII hereby expressly waives to the maximum extent
permitted by applicable law each and every right to which it may be entitled by virtue of the
suretyship laws of the State of Texas or any other state in which it may be located, including any
and all rights it may have pursuant to Rule 31, Texas Rules of Civil Procedure, Section 17.001 of
the Texas Civil Practice and Remedies Code and Chapter 34 of the Texas Business and Commerce Code.
WII hereby waives marshaling of assets and liabilities, notice by the Administrative Agent, the
Issuing Bank or any Lender of any indebtedness or liability to which such Person applies or may
apply any amounts received by it, and of the creation, advancement, increase, existence, extension,
renewal, rearrangement or modification of the Guaranteed Obligations. WII expressly waives, to the
extent permitted by

67

 

applicable law, the benefit of any and all laws providing for exemption of
property from execution or for valuation and appraisal upon foreclosure.

     SECTION 11.05. Agreement to Defer Exercise of Subrogation. Notwithstanding any payment or
payments made by WII hereunder, or any setoff or application by the Administrative Agent or any
Lender of any security or of any credits or claims, WII will not assert or exercise any rights of
the Administrative Agent or any Lender or of itself against any Borrower to recover the amount of
any payment made hereunder by WII to the Administrative Agent or any Lender by way of any claim,
remedy or subrogation, reimbursement, exoneration, contribution, indemnity, participation or
otherwise arising by contract, by statute, under common law or otherwise, and WII shall not have
any right to exercise any right of recourse to or any claim against assets or property of any
Borrower for such amounts, in each case unless and until the Obligations of such Borrower
guaranteed hereby have
been fully and finally satisfied. Until such time (but not thereafter), WII hereby agrees not to
exercise any claim, right or remedy which it may now have or hereafter acquire against any Borrower
that arises under this Agreement or any other Loan Document or from the performance by WII of the
Guaranty hereunder including any claim, remedy or right of subrogation, reimbursement, exoneration,
contribution, indemnification or participation in any claim, right or remedy of the Administrative
Agent or any Lender against any Borrower or WII, or any security that the Administrative Agent or
any Lender now has or hereafter acquires pursuant hereto securing the Obligations of the Borrowers
under this Agreement, whether or not such claim, right or remedy arises in equity, under contract,
by statute, under common law or otherwise. If any amount shall be paid to WII by any Borrower
after payment in full of the Obligations, and the Obligations shall thereafter be reinstated in
whole or in part and the Administrative Agent or any Lender forced to repay any sums received by
any of them in payment of the Obligations, this Guaranty shall be automatically reinstated and such
amount shall be held in trust for the benefit of the Administrative Agent and the Lenders and shall
forthwith be paid to the Administrative Agent to be credited and applied to the Guaranteed
Obligations, whether matured or unmatured. The provisions of this paragraph shall survive the
termination of this Guaranty, and any satisfaction and discharge of any Borrower by virtue of any
payment, court order or any federal or state law.

     SECTION 11.06. Full Force and Effect. This Guaranty is a continuing guaranty and, subject
to Section 11.07, shall remain in full force and effect until all of the Guaranteed
Obligations under this Agreement and the other Loan Documents to which any Borrower is a party and
all other amounts payable under this Guaranty have been paid in full (after the termination of the
Commitments). All rights, remedies and powers provided in this Guaranty may be exercised, and all
waivers contained in this Guaranty may be enforced, only to the extent that the exercise or
enforcement thereof does not violate any provisions of applicable law which may not be waived.

     SECTION 11.07. Guaranty Fall-Away Notwithstanding anything contained herein to the
contrary, if at any time WII has no outstanding Specified Debt, exclusive of (a) the Guaranty,
(b) any guarantee that, by its terms, will be automatically released and discharged simultaneously
with the release and discharge of the Guaranty and (c) Specified Debt owed to WIL or any of WIL’s
other Subsidiaries, the Guaranty will terminate; provided that the Guaranty will be automatically
reinstated if WII incurs or guarantees any Specified Debt other than Specified Debt owed to WIL or
any of WIL’s other Subsidiaries. The Administrative Agent shall notify

68

 

the Lenders of any
termination of the Guaranty or automatic reinstatement of the Guaranty pursuant to this
Section 11.07.

ARTICLE XII

MISCELLANEOUS

     SECTION 12.01. Waiver; Amendments; Joinder; Removal of Certain Borrowers.

          (a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in
exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right or power, or any abandonment or discontinuance of steps to
enforce such a right or power, preclude any other or further exercise thereof or the exercise of
any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank
and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they
would otherwise have. No waiver of any provision of this Agreement or consent to any departure by
any Obligor therefrom shall in any event be effective unless the same shall be permitted by
paragraph (b) of this Section, and then such waiver or consent shall be effective only in
the specific instance and for the purpose for which given. Without limiting the generality of the
foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a
waiver of any Default or Event of Default, regardless of whether the Administrative Agent, any
Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

          (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except
pursuant to an agreement or agreements in writing entered into by the Obligors and the Required
Lenders or by the Obligors and the Administrative Agent with the consent of the Required Lenders;
provided that no such agreement shall (i) increase the Commitment of any Lender without the written
consent of such Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce
the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of
each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount
of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce
the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of
any Commitment, without the written consent of each Lender affected thereby, (iv) change
Section 4.01(b) or 4.01(c) in a manner that would alter the pro rata sharing of
payments required thereby, without the written consent of each Lender, (v) change any of the
provisions of this Section or the definition of “Required Lenders” or any other provision hereof
specifying the number or percentage of Lenders required to waive, amend or modify any rights
hereunder or make any determination or grant any consent hereunder, without the written consent of
each Lender, (vi) except as provided in Section 12.01(d), release any Borrower from its
joint and several liability for the Obligations, without the written consent of each Lender, or
(vii) release any Person from its liability under a guaranty, without the written consent of each
Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights
or duties of the Administrative Agent or the Issuing Bank hereunder without the prior written
consent of the Administrative Agent or the Issuing Bank, as the case may be. Subject to the
foregoing, the waiver, amendment or modification of any provision of Article VI,
VII or VIII or Section 9.01 may be effected with the consent of the
Required Lenders.

69

 

          (c) From time to time, WIL may cause one or more additional Subsidiaries to become Borrowers
hereunder by delivering, or causing to be delivered, to the Administrative Agent in respect of each
applicable Subsidiary, the following, each in form and substance satisfactory to the Administrative
Agent: (i) a Joinder Agreement in the form of Exhibit G attached hereto, executed and
delivered by such Subsidiary (the date of each such Joinder Agreement being referred to herein as a
“Joinder Date”, which date shall be at least ten days after WIL provides notice to the
Administrative Agent and each Lender of its intention to cause such
Subsidiary to become a Borrower hereunder), (ii) each of the documents or other closing
deliverables specified in Section 5.01 that would have been required to be delivered by or
on behalf of such Subsidiary had such Subsidiary been a Borrower on the Effective Date, each such
deliverable to be dated as of the applicable Joinder Date unless otherwise agreed by the
Administrative Agent, (iii) replacement Notes dated as of the applicable Joinder Date payable to
each Lender for which an existing Note is outstanding on such Joinder Date and (iv) such other
approvals, opinions or documents as the Administrative Agent may request; provided that no
Subsidiary may become a Borrower hereunder pursuant to this paragraph (c) if (y) a Default
or Event of Default shall have occurred and be continuing on the applicable Joinder Date, or shall
result from the joinder of such Subsidiary as a Borrower on such Joinder Date or (z) if WIL shall
designate an additional Subsidiary as a Borrower hereunder that is not organized under the laws of
any jurisdiction of the United States; and any Lender notifies the Administrative Agent that such
Subsidiary is organized in a jurisdiction in which it and its Affiliates cannot legally lend or do
business. Without limiting the foregoing, if the designation of any additional Subsidiary as a
Borrower hereunder obligates the Administrative Agent or any Lender to comply with “know your
customer” or similar regulatory requirements and the information necessary for such compliance is
not already available to the Administrative Agent or such Lender, as applicable, WIL shall,
promptly upon the request of the Administrative Agent or such Lender, as applicable, supply such
documentation and other evidence as is reasonably requested by the Administrative Agent or such
Lender, as applicable, in order for it to comply with all “know your customer” and/or similar
identification procedures required under all applicable laws and regulations. If WIL shall
designate an additional Subsidiary as a Borrower hereunder that is not organized under the laws of
any jurisdiction of the United States, any Lender may, with notice to the Administrative Agent and
WIL, fulfill its Commitment by causing an Affiliate of such Lender to act as the Lender in respect
of such Borrower (and such Lender shall, to the extent of Loans made to and participations in
Letters of Credit issued for the account of such Borrower, be deemed for all purposes hereof to
have pro tanto assigned such Loans and participations to such Affiliate in compliance with the
provisions of Section 12.05).

          (d) From time to time, WIL may cause any Borrower (other than WIL) to cease to be a Borrower
hereunder by (i) delivering to the Administrative Agent a notice to such effect, specifying the
identity of the applicable Borrower and the proposed date on which such Borrower shall no longer be
a Borrower hereunder, which date shall be no earlier than three Business Days after delivery of
such notice (each such date being referred to herein as a “Borrower Removal Date”) and
(ii) delivering, or causing to be delivered, to the Administrative Agent replacement Notes dated as
of the applicable Borrower Removal Date payable to each Lender for which an existing Note is
outstanding on such Borrower Removal Date, executed by WIL and each other Borrower that shall not
cease to be a Borrower on such Borrower Removal Date, in form and substance satisfactory to the
Administrative Agent; provided that no Borrower may cease to be a Borrower hereunder pursuant to
this Section 12.01(d) if a Default or Event of

70

 

Default shall have occurred and be
continuing on the applicable Borrower Removal Date, or shall result from such Borrower ceasing to
be a Borrower hereunder on such Borrower Removal Date. Upon satisfaction of the conditions set
forth in the preceding sentence, on the applicable Borrower Removal Date, the applicable Borrower
shall no longer be a “Borrower” or an “Obligor” hereunder or under any other Loan Document.
Notwithstanding anything to the contrary contained herein, in the event that any Borrower shall
cease to be a Borrower hereunder in accordance with this Section 12.01(d), the other
Obligors shall remain jointly and severally
liable with respect to each Loan made to such Borrower and each Letter of Credit issued for
the account of such Borrower outstanding on the applicable Borrower Removal Date.

     SECTION 12.02. Notices.

          (a) All notices and other communications provided for herein, including any modifications of,

mailed or delivered to the intended recipient at the “Address for Notices” specified below its name
on the signature pages hereof (or provided for in an Assignment and Assumption); or, as to any

accordance with this Section 12.02) (i) as to any Obligor, to the Administrative Agent,
(ii) as to the Administrative Agent, to any Obligor, and to each Lender, and (iii) as to any
Lender, to any Borrower and to the Administrative Agent. Except as otherwise provided in this
Agreement, all such Communications shall be deemed to have been duly given (1) when transmitted by

Notwithstanding the foregoing, Communications to the Administrative Agent pursuant to
Article II, Article III, Article IV, Article X, Article XI
or Article XII shall not be effective until received by the Administrative Agent.

          (b) Notices and other communications to the Lenders hereunder may be delivered or furnished by
electronic communications pursuant to procedures approved by the Administrative Agent; provided
that the foregoing shall not apply to notices pursuant to Article II unless otherwise
agreed by the Administrative Agent and the applicable Lender. The Administrative Agent or any
Obligor may, in its discretion, agree to accept notices and other communications to it hereunder by
electronic communications pursuant to procedures approved by it; provided that approval of such
procedures may be limited to particular notices or communications.

     SECTION 12.03. Expenses, Etc. The Borrowers, jointly and severally, shall pay (a) all
reasonable out of pocket expenses incurred by the Administrative Agent and its Affiliates,
including the reasonable fees, charges and disbursements of counsel for the Administrative Agent,
in connection with the syndication of the credit facilities provided for herein, the preparation
and administration of this Agreement and the other Loan Documents or any amendments, modifications
or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby
or thereby shall be consummated), (b) all reasonable out-of-

71

 

pocket expenses incurred by the Issuing
Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or
any demand for payment thereunder, (c) all transfer, stamp, documentary or other similar taxes,
assessments or charges levied by any governmental or revenue authority in respect of this
Agreement or any other Loan Document or any other document referred to herein or therein, and
(d) all out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank and/or any
Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent,
the Issuing Bank and/or any Lender, in connection with the enforcement or protection of its rights
in connection with this Agreement, including its rights under this Section, or in connection with
the Loans made or Letters of Credit issued hereunder, including all such out-of pocket expenses
incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of
Credit.

     SECTION 12.04. Indemnity.

          (a) The Borrowers, jointly and severally, shall indemnify the Administrative Agent, the
Issuing Bank and each Lender, and each Affiliate thereof, and their respective directors, officers,
employees and agents (each such Person being called an “Indemnitee”) from, and hold each
Indemnitee harmless against, any and all losses, liabilities, claims or damages (including
reasonable legal fees and expenses) to which any Indemnitee may become subject, insofar as such
losses, liabilities, claims or damages arise out of or result from (i) any claim, investigation,
litigation or proceeding (including any threatened claim, investigation, litigation or proceeding)
relating to this Agreement, any Loan, any Letter of Credit or any other Loan Document (whether or
not such Indemnitee is a party thereto) or (ii) any actual or proposed use by either Borrower or
any of its Subsidiaries of the proceeds of any extension of credit by any Lender or the Issuing
Bank hereunder, and the Borrowers, jointly and severally, shall reimburse each Indemnitee upon
demand for any expenses (including reasonable legal fees) incurred in connection with any such
claim, investigation, litigation or proceeding; but excluding any such losses, liabilities, claims,
damages or expenses incurred by reason of the gross negligence, willful misconduct or unlawful
conduct of such Indemnitee. WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT, IT IS THE EXPRESS
INTENTION OF THE PARTIES HERETO THAT EACH INDEMNITEE HEREUNDER SHALL BE INDEMNIFIED AND HELD
HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS OR DAMAGES ARISING OUT OF OR RESULTING
FROM THE SOLE OR CONCURRENT ORDINARY NEGLIGENCE OF SUCH INDEMNITEE. WITHOUT PREJUDICE TO THE
SURVIVAL OF ANY OTHER OBLIGATIONS OF THE BORROWERS HEREUNDER AND UNDER THE OTHER LOAN DOCUMENTS TO
WHICH IT IS A PARTY, THE OBLIGATIONS OF THE BORROWERS UNDER THIS SECTION 12.04 SHALL
SURVIVE THE TERMINATION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE PAYMENT OF THE
OTHER OBLIGATIONS OR THE ASSIGNMENT OF THE NOTES.

          (b) To the extent that any Borrower fails to pay any amount required to be paid by it to the
Administrative Agent or the Issuing Bank under Section 12.03 or paragraph (a) of
this Section, each Lender severally agrees to pay to the Administrative Agent or the Issuing Bank,
as the case may be, such Lender’s Applicable Percentage (determined as of the time that the
applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided
that the unreimbursed expense or indemnified loss, claim, damage, liability or related

72

 

expense, as the case may be, was incurred by or asserted against the Administrative Agent or
the Issuing Bank in its capacity as such.

          (c) To the extent permitted by applicable law, no Obligor shall assert, and each hereby
waives, any claim against any Indemnitee, on any theory of liability, for special, indirect,
consequential or punitive damages (as opposed to direct or actual damages) arising out of, in
connection with, or as a result of, this Agreement, any other Loan Document or any agreement or
instrument contemplated hereby or thereby, the transactions contemplated hereby or thereby, any
Loan or Letter of Credit or the use of the proceeds thereof.

     SECTION 12.05. Successors and Assigns.

          (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns permitted hereby (including any
Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) no Obligor may
assign or otherwise transfer any of its rights or obligations hereunder without the prior written
consent of each Lender (and any attempted assignment or transfer by such Obligor without such
consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or
obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed
or implied, shall be construed to confer upon any Person (other than the parties hereto, their
respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank
that issues any Letter of Credit), Participants (to the extent provided in paragraph (c) of
this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the
Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or
claim under or by reason of this Agreement.

     (b) (i) Subject to the conditions set forth in subparagraph (b)(ii) below, any
Lender may assign to one or more assignees all or a portion of its rights and obligations
under this Agreement (including all or a portion of its Commitment and the Loans at the time
owing to it) with the prior written consent (such consent not to be unreasonably withheld)
of:

          (A) WIL, provided that no consent of WIL shall be required for an assignment to
a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has
occurred and is continuing, any other assignee;

          (B) the Administrative Agent, provided that no consent of the Administrative
Agent shall be required for an assignment of any Commitment to an assignee that is a
Lender with a Commitment immediately prior to giving effect to such assignment; and

          (C) the Issuing Bank.

          (ii) Assignments shall be subject to the following additional conditions:

          (A) except in the case of an assignment to a Lender or an Affiliate of a Lender
or an assignment of the entire remaining amount of the

73

 

assigning Lender’s Commitment
or Loans of any Type, the amount of the Commitment or Loans of the assigning Lender
subject to each such assignment (determined as of the date the Assignment and
Assumption with respect to such assignment is delivered to the Administrative Agent)
shall not be less than $5,000,000 unless each of WIL and the Administrative Agent
otherwise consent, provided that no such consent of WIL shall be required if an
Event of Default under Section 9.01(a), 9.01(f) or 9.01(g)
has occurred and is continuing;

          (B) each partial assignment shall be made as an assignment of a proportionate
part of all the assigning Lender’s rights and obligations under this Agreement;

          (C) the parties to each assignment shall execute and deliver to the
Administrative Agent an Assignment and Assumption, together with a processing and
recordation fee of $3,500;

          (D) the assignee, if it shall not be a Lender, shall deliver to the
Administrative Agent an Administrative Questionnaire;

          (E) except in connection with assignments made while an Event of Default has
occurred and is continuing, all prospective assignees of a Lender shall be required,
as a condition to the effectiveness of such assignment, to execute and deliver the
forms required under Section 4.02(e) for any Lender, and no assignment shall
be effective in connection herewith unless and until such forms are so delivered;

          (F) no assignment shall be made to any Lender if after giving effect to such
assignment, such Lender’s Commitment Percentage would exceed [35%]; and

          (G) in the case of any assignee subject to the prior written consent of WIL
under Section 12.05(b)(i), no assignment shall be made to any such assignee
unless such assignee provides a written representation to WIL that such assignee is
not subject under then current law to any withholding tax on amounts payable to such
assignee under this Agreement.

     For purposes of this Section 12.05, the term “Approved Fund” has the following
meaning:

“Approved Fund” means any Person (other than a natural person) that is engaged in
making, purchasing, holding or investing in bank loans and similar extensions of credit in
the ordinary course of its business and that is administered or managed by (a) a Lender,
(b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers
or manages a Lender.

          (iii) Subject to acceptance and recording thereof pursuant to
subparagraph (b)(iv) of this Section, from and after the effective date specified in
each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the

74

 

extent of the interest assigned by such Assignment and Assumption, have the rights and
obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to
the extent of the interest assigned by such Assignment and Assumption, be released from its
obligations under this Agreement (and, in the case of an Assignment and Assumption covering
all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall
cease to be a party hereto but shall continue to be entitled to the benefits of Sections
2.11, 2.12, 4.02, 12.03 and 12.04). Any assignment or
transfer by a Lender of rights or obligations under this Agreement that does not comply with
this Section 12.05 shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
paragraph (c) of this Section.

          (iv) The Administrative Agent, acting for this purpose as an agent of the Borrowers,
shall maintain at one of its offices a copy of each Assignment and Assumption delivered to
it and a register for the recordation of the names and addresses of the Lenders, and the
Commitment of, and principal amount of the Loans and LC Disbursements owing by each Borrower
to, each Lender pursuant to the terms hereof from time to time (the “Register”).
The entries in the Register shall be presumed correct, in the absence of manifest error, and
the Obligors, the Administrative Agent, the Issuing Bank and the Lenders may 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 by the Obligors, the Issuing Bank and any Lender,
at any reasonable time and from time to time upon reasonable prior notice.

          (v) Upon its receipt of a duly completed Assignment and Assumption executed by an
assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire
(unless the assignee shall already be a Lender hereunder), the processing and recordation
fee referred to in paragraph (b) of this Section and any written consent to such
assignment required by paragraph (b) of this Section, the Administrative Agent shall
accept such Assignment and Assumption and record the information contained therein in the
Register; provided that if either the assigning Lender or the assignee shall have failed to
make any payment required to be made by it pursuant to Section 2.03, 3.01(d)
or (e), 4.01(d) or 12.04(b), the Administrative Agent shall have no
obligation to accept such Assignment and Assumption and record the information therein in
the Register unless and until such payment shall have been made in full, together with all
accrued interest thereon. No assignment shall be effective for purposes of this Agreement
unless it has been recorded in the Register as provided in this paragraph.

     (c) (i) Any Lender may, without the consent of any Obligor, the Administrative Agent or
the Issuing Bank, sell participations to one or more banks or other entities (a
“Participant”) in all or a portion of such Lender’s rights and obligations under
this Agreement (including all or a portion of its Commitment and the Loans owing
to it); provided that (A) such Lender’s obligations under this Agreement shall remain
unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for
the performance of such obligations and (C) the Borrowers, the Administrative Agent, the

75

 

Issuing Bank and the other Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender’s rights and obligations under this Agreement. Any
agreement or instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Agreement and to approve any
amendment, modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver described in the first proviso
to Section 12.01(b) that affects such Participant. Subject to
subparagraph (c)(ii) of this Section, each Borrower agrees that each Participant
shall be entitled to the benefits of Sections 2.11, 2.12 and 4.02 to
the same extent as if it were a Lender and had acquired its interest by assignment pursuant
to paragraph (b) of this Section. To the extent permitted by law, each Participant
also shall be entitled to the benefits of Section 9.02 as though it were a Lender,
provided such Participant agrees to be subject to Section 4.01(b), and to deliver
the forms required by Section 4.02(e), as though it were a Lender.

          (ii) A Participant shall not be entitled to receive any greater payment under
Sections 2.11 and 4.02 than the applicable Lender would have been entitled
to receive with respect to the participation sold to such Participant, unless the sale of
the participation to such Participant is made with WIL’s prior written consent. A
Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the
benefits of Section 4.02 unless WIL is notified of the participation sold to such
Participant and such Participant agrees, for the benefit of the Borrowers, to comply with
Section 4.02(d) and Section 4.02(e) as though it were a Lender.

          (d) Any Lender may at any time pledge or assign a security interest in all or any portion of
its rights under this Agreement to secure obligations of such Lender, including without limitation
any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall
not apply to any such pledge or assignment of a security interest; provided that no such pledge or
assignment of a security interest shall release a Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto.

     SECTION 12.06. Confidentiality. Each of the Administrative Agent, the Issuing Bank and the
Lenders agrees to maintain the confidentiality of the Information (as defined below), except that
Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and
agents, including accountants, legal counsel and other advisors (it being understood that the
Persons to whom such disclosure is made will be informed of the confidential nature of such
Information and instructed to keep such Information confidential), (b) to the extent requested by
any regulatory authority or self-regulatory body having or claiming jurisdiction over such Person
or its Affiliates, (c) to the extent required by applicable laws or regulations or by any subpoena
or similar legal process, (d) to any other party to this Agreement or any other Loan Document,
(e) in connection with the
exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or
any other Loan Document or the enforcement of rights hereunder, (f) subject to an agreement
containing provisions substantially the same as those of this Section, to (i) any assignee of or
Participant in, or any prospective assignee of or Participant in, any of its rights or obligations
under this Agreement or any other

76

 

Loan Document or (ii) any actual or prospective counterparty (or
its advisors) to any swap or derivative transaction relating to any Obligors and their respective
obligations, (g) with the consent of the applicable Obligors or (h) to the extent such Information
(i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes
available to the Administrative Agent, the Issuing Bank or any Lender on a non-confidential basis
from a source other than an Obligor. For the purposes of this Section, “Information” means
all information received from any Obligor relating to such Obligor or any other Obligor or their
respective businesses, other than any such information that is available to the Administrative
Agent, the Issuing Bank or any Lender on a non-confidential basis prior to disclosure by the
applicable Obligor; provided that such information is clearly identified at the time of delivery as
confidential. Any Person required to maintain the confidentiality of Information as provided in
this Section shall be considered to have complied with its obligation to do so if such Person has
exercised the same degree of care to maintain the confidentiality of such Information as such
Person would accord to its own confidential information. Each of the Administrative Agent, the
Issuing Bank and the Lenders shall endeavor to notify WIL as promptly as possible of any
Information that it is required to disclose pursuant to any subpoena or similar legal process so
long as it is not legally prohibited from providing such notice.

     SECTION 12.07. Survival. All covenants, agreements, representations and warranties made by
the Obligors herein, in the other Loan Documents and in the certificates or other instruments
delivered in connection with or pursuant to this Agreement and the other Loan Documents shall be
considered to have been relied upon by the other parties hereto and thereto and shall survive the
execution and delivery of this Agreement and the other Loan Documents and the making of any Loans
and issuance of any Letters of Credit, regardless of any investigation made by any such other party
or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender
may have had notice or knowledge of any Default or incorrect representation or warranty at the time
any credit is extended hereunder, and shall continue in full force and effect as long as the
principal of or any accrued interest on any Loan or any fee or any other amount payable under this
Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the
Commitments have not expired or terminated. The provisions of Sections 2.11, 2.12,
4.02, 12.03 and 12.04 and Article X shall survive and remain in
full force and effect regardless of the consummation of the transactions contemplated hereby, the
repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments
or the termination of this Agreement or any provision hereof.

     SECTION 12.08. Governing Law. This Agreement, all Notes, the other Loan Documents and all
other documents executed in connection herewith and therewith and the rights and obligations of the
parties hereto and thereto, shall be construed in accordance with and governed by the law of the
State of New York.

     SECTION 12.09. Independence of Covenants. All covenants contained in this Agreement and in
the other Loan Documents shall be given independent effect so that if a particular action or
condition is not permitted by any of such covenants, the fact that such action or condition would
be permitted by an exception to, or otherwise be within the limitations of, another covenant, shall
not avoid the occurrence of a Default or an Event of Default if such action is taken or condition
exists.

77

 

     SECTION 12.10. Counterparts; Integration; Effectiveness. This Agreement may be executed in
counterparts (and by different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a single contract.
This Agreement, the Notes, the other Loan Documents and any separate letter agreements with respect
to fees payable to the Administrative Agent constitute the entire contract among the parties
relating to the subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. This Agreement shall
become effective on the Effective Date, and thereafter shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns. Delivery of an executed
counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a
manually executed counterpart of this Agreement.

     SECTION 12.11. Severability. Any provision of this Agreement held to be invalid, illegal
or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent
of such invalidity, illegality or unenforceability without affecting the validity, legality and
enforceability of the remaining provisions hereof, and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

     SECTION 12.12. Conflicts Between This Agreement and the Other Loan Documents. In the event
of any conflict between, or inconsistency with, the terms of this Agreement and the terms of any of
the other Loan Documents, the terms of this Agreement shall control.

     SECTION 12.13. Headings. Article and Section headings and the Table of Contents used
herein are for convenience of reference only, are not part of this Agreement and shall not affect
the construction of, or be taken into consideration in interpreting, this Agreement.

     SECTION 12.14. Limitation of Interest. Notwithstanding anything herein to the contrary, if
at any time the interest rate applicable to any Loan, together with all fees, charges and other
amounts which are treated as interest on such Loan under applicable law (collectively the
“Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be
contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance
with applicable law, the rate of interest payable in respect of such Loan hereunder, together with
all Charges payable in respect thereof, shall be
limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have
been payable in respect of such Loan but were not payable as a result of the operation of this
Section shall be cumulated and the interest and Charges payable to such Lender in respect of other
Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated
amount, together with interest thereon at the Federal Funds Effective Rate to the date of
repayment, shall have been received by such Lender.

     SECTION 12.15. Submission to Jurisdiction; Consent to Service of Process.

          (a) Each Obligor hereby irrevocably and unconditionally submits, for itself and its property,
to the non-exclusive jurisdiction of the Supreme Court of the State of New York sitting in New York
County and of the United States District Court of the Southern District of New York, and any
appellate court from any thereof, in any action or proceeding arising out of or relating to this
Agreement or any other Loan Document, or for recognition or enforcement of

78

 

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 such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that a final 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 or any
other Loan Document shall affect any right that the Administrative Agent, the Issuing Bank or any
Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other
Loan Document against any Obligor or its properties in the courts of any jurisdiction.

          (b) Each Obligor hereby irrevocably and unconditionally waives, to the fullest extent it may
legally and effectively do so, any objection which it may now or hereafter have to the laying of
venue of any suit, action or proceeding arising out of or relating to this Agreement or any other
Loan Document in any court referred to in paragraph (a) of this Section. Each of the
parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such court.

          (c) Each party to this Agreement irrevocably consents to service of process in the manner
provided for notices in Section 12.02. Nothing in this Agreement or any other Loan
Document will affect the right of any party to this Agreement or any other Loan Document to serve
process in any other manner permitted by law.

     SECTION 12.16. Waiver of Jury Trial. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL
PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER LOAN
DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY (WHETHER BASED ON CONTRACT, TORT OR
ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF
ANY OTHER PARTY HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION,
SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE
BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE
MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     SECTION 12.17. Judgment Currency. The obligation of each Obligor to make payments on any
Obligation to the Lenders, to the Issuing Bank or to the Administrative Agent hereunder in any
currency (the “first currency”) shall not be discharged or satisfied by any tender or
recovery pursuant to any judgment expressed in or converted into any other currency (the
“second currency”) except to the extent to which such tender or recovery shall result in
the effective receipt by the applicable Lender, Issuing Bank or the Administrative Agent of the
full amount of the first currency payable, and accordingly the primary obligation of each Obligor
shall be enforceable as an alternative or additional cause of action for the purpose of recovery in
the second currency of the amount (if any) by which such effective receipt shall fall short of the

79

 

full amount of the full currency payable and shall not be affected by a judgment being obtained for
any other sum due hereunder.

     SECTION 12.18. USA Patriot Act. Each Lender that is subject to the requirements of the USA
Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”)
hereby notifies the Obligors that pursuant to the requirements of the Act, it is required to
obtain, verify and record information that identifies each Obligor, which information includes the
name and address of such Obligor and other information that will allow such Lender to identify such
Obligor in accordance with the Act.

     SECTION 12.19. No Fiduciary Duty. Each of the Administrative Agent, each Lender and their
Affiliates (collectively, solely for purposes of this paragraph, the “Lenders”), may have economic
interests that conflict with those of the Obligors. Each Obligor agrees that nothing in the Loan
Documents or otherwise associated with this facility will be deemed to create an advisory,
fiduciary or agency relationship or fiduciary or other implied duty between the Lenders and the
Borrower, its stockholders or its affiliates. Each Obligor acknowledges and agrees that (i) the
transactions contemplated by the Loan Documents are arm’s-length commercial transactions between
the Lenders, on the one hand, and the Obligors, on the other, (ii) in connection therewith and with
the process leading to such transaction each of the Lenders is acting solely as a principal and not
the agent or fiduciary of an Obligor, its management, stockholders, creditors or any other person,
(iii) no Lender has assumed an advisory or fiduciary responsibility in favor of an Obligor with
respect to the transactions contemplated hereby or the process leading thereto (irrespective of
whether any Lender or any of its affiliates has advised or is currently advising an Obligor on
other matters, including the Public Debt Offering, the terms of which advisory role, if any, shall
be governed by a separate agreement) or any other obligation to each Obligor except the obligations
expressly set forth in the Loan Documents and (iv) each Obligor has consulted its
own legal and financial advisors to the extent it deemed appropriate. Each Obligor further
acknowledges and agrees that it is responsible for making its own independent judgment with respect
to such transactions and the process leading thereto. Each Obligor agrees that it will not claim
that any Lender has rendered advisory services of any nature or respect, or owes a fiduciary or
similar duty to such Obligor, in connection with such transaction or the process leading thereto.
Nothing in this paragraph shall affect any obligations between affiliates of the Lenders and the
Obligors that may arise in connection with the Public Debt Offering or any other matter, the terms
of which obligations, if any, shall be solely as set forth in a separate agreement.

     WEATHERFORD INTERNATIONAL LTD., a Bermuda exempted company (the “Borrower”), for value
received promises and agrees to pay to                                         (the “Lender”), or
