has all requisite power and authority to own, lease and operate its properties and to carry on
its business as now being conducted. Each of the Transferred Subsidiaries is duly qualified or
registered to transact business under the Laws of each jurisdiction in which the failure to be so

equity or ownership interest of any kind in any business, joint venture, or other Person. The
copies of the organizational documents of each Transferred Subsidiary heretofore made available
to Buyer are true, complete and correct copies of such instruments as presently in effect.

Agreement and the Seller Ancillary Documents and to perform its obligations under this Agreement
and the Seller Ancillary Documents and to consummate the transactions contemplated hereby and

consummation of the transactions provided for herein and therein have been duly and validly
authorized. This Agreement has been, and each of the Seller Ancillary Documents will be as of

of this Agreement and the Seller Ancillary Documents, the consummation of the transactions
contemplated by this Agreement and the Seller Ancillary Documents, and the fulfillment of and
compliance with the terms and conditions of this Agreement and the Seller Ancillary Documents do
not or will not (as the case may be), with the passing of time or the giving of notice or both,
violate or conflict with, constitute a breach of or default under, result in the loss of any
benefit under, permit the acceleration of any obligation under or create in any party the right
to terminate, modify or cancel, (a) any term or provision of the organizational documents of
Seller or any Transferred Subsidiary, (b) any Material Contract, (c) any judgment, decree or
order of any court or Governmental Entity by which Seller or any Transferred Subsidiary is bound
or (d) any Law or arbitration award applicable to Seller or any Transferred Subsidiary, except in
any case under clauses (b), (c) or (d) above, where the loss, termination, breach, acceleration,
modification or cancellation would not reasonably be expected to have a Material Adverse Effect
on the Transferred Subsidiaries. The transactions contemplated by this Agreement will not
constitute a change of control or assignment requiring the consent from a third party pursuant to
any Material Contract. No consent, approval, order or authorization of, or registration,
declaration or filing with, any Governmental Entity is required with respect to Seller or any of
its Affiliates in connection with the execution, delivery or performance of this Agreement or the
Seller Ancillary Documents or the consummation of the transactions contemplated hereby or
thereby, except (x) such reports under the Securities Exchange Act of 1934, as amended (including
the rules and regulations thereunder), as may be required in connection with this Agreement and

Filing”), and except where the failure to obtain such consent, approval, order, authorization or
registration or the failure to make such declaration or filing would not reasonably be expected
to have a Material Adverse Effect on the Transferred Subsidiaries.

SECTION 3.4 Ownership of the Transferred Subsidiaries and Certain Other Subsidiaries.

(a) The identity of each Person that owns any outstanding Equity Interest in a Transferred
Subsidiary and the number of shares, or amount of such interest, owned by such Person is set forth
on Schedule 3.4. Each such Person has good and marketable title to such Equity Interests.
There is no agreement, understanding, trust, or other collaborative arrangement or understanding
with any party other than Seller that could reasonably be expected to have a Material Adverse
Effect on such Person’s ownership of such Equity Interests. Except as set forth in Schedule
3.4, such Equity Interests are owned free and clear of all Liens. Upon the delivery by Seller
of the certificates representing the Equity Interests in WFIL and WFI France in the manner
contemplated in this Agreement, Buyer will acquire the beneficial and legal, valid and indefeasible
title to such Equity Interests, free and clear of all Liens. Upon the delivery by WFI UK, Ltd. of
the certificate representing the Equity Interest in WFI Turkey described in clause (iii) of
Section 5.1(c), WFI Sweden will acquire the beneficial and legal, valid and indefensible
title to such Equity Interest, free and clear of all Liens. Except as contemplated by Section

SECTION 3.5 Validity of Intercompany Debt; Nature of Debt Released Pursuant to Deed of
Release.

Transferred Subsidiaries to Seller. The portion of the Intercompany Debt designated in
Schedule A as “Loans” constitutes debts arising from transactions for the lending of money
which fall to be settled by the payment of money, and does not constitute trade debts. Seller has
the right to transfer the Assigned Intercompany Debt to Buyer hereunder. The assignment of the
Assigned Intercompany Debt to Buyer hereunder does not violate any contract, order, judgment, writ
or Law applicable to Seller or the Transferred Subsidiaries. Upon consummation of the transactions
described in clauses (iv) and (v) of Section 5.1(c), Seller will have no further right to
receive payment of principal or interest from the Transferred Subsidiaries in respect of the
Non-Assigned Intercompany Debt. Upon assignment hereunder, Seller will have no further right to
receive payment of principal or interest from the Transferred Subsidiaries in respect of the
Assigned Intercompany Debt.

Release constitutes debts arising from transactions for the lending of money which fall to be
settled by the payment of money, and does not constitute trade debts.

claims, disputes or controversies that would not reasonably be expected to have a Material Adverse
Effect on the Transferred Subsidiaries. No Transferred Subsidiary has suffered or sustained any
work stoppage and, to Seller’s Knowledge, no such work stoppage is threatened against any
Transferred Subsidiary.

(d) Neither Seller nor any Transferred Subsidiary is a party to any contract, agreement or
arrangement with any labor union or employee association with respect to employees of any

organize or establish any labor union or employee association with respect to any of the employees
of any Transferred Subsidiary, and there is no existing or pending certification of any such union
with regard to a bargaining unit. The Transferred Subsidiaries have performed and discharged in
all material respects their respective obligations with respect to works councils and other staff
representatives, staff representative bodies and institutions representing all or part of the
individuals required to be identified pursuant to Section 3.13 (a).

SECTION 3.14 Benefit Plans.

(a) Schedule 3.14(a) sets forth a true and correct list of each material Employee
Benefit Plan or arrangement that is maintained or contributed to by any of the Transferred
Subsidiaries or in which any current or former employee of the Transferred Subsidiaries

that any Transferred Subsidiary maintains or to which any Transferred Subsidiary makes
contributions or in which any current or former employee of Transferred Subsidiaries participates
is subject to ERISA or the Code. No Transferred Subsidiary nor any trade or business, whether or
not incorporated, which together with any Transferred Subsidiary would be deemed a “single
employer” within the meaning of Section 4001 of ERISA (each Subsidiary and each such trade or
business is referred to herein as an “ERISA Affiliate”), has maintained or made contributions to
any Employee Benefit Plan subject to Section 412 of the Code or Title IV of ERISA for the six-year
period prior to the date of this Agreement.

(b) No Transferred Subsidiary nor any ERISA Affiliate has been obligated to make contributions
to any Employee Benefit Plan subject to ERISA that is a multiemployer plan (within the meaning of
Section 3(37) of ERISA), and no Transferred Subsidiary nor any ERISA Affiliate has made
contributions to any Employee Benefit Plan subject to ERISA that is a multiple employer plan as
defined in Section 413 of the Code for the six-year period prior to the date of this Agreement.
All contributions or other amounts payable by Seller or any of the Transferred Subsidiaries as of
the Closing Date with respect to each Employee Benefit Plan or arrangement that is maintained or
contributed to by any of the Transferred Subsidiaries or in which any current or former employee of
the Transferred Subsidiaries participates in respect of current or prior plan years have been
either paid or accrued on the Unaudited Interim Balance Sheet, except to the extent the failure to
make or accrue such payments would not reasonably be expected to have a Material Adverse Effect.

(c) Except as set forth on Schedule 3.14(c), no employee of a Transferred Subsidiary
is subject to Section 280G or Section 409A of the Code. No material Employee Benefit Plan or
arrangement that is maintained or contributed to by any of the Transferred Subsidiaries or in which
any current or former employee of the Transferred Subsidiaries participates provides death or
medical benefits (whether or not insured) beyond their retirement or other termination of service
the cost of which is material to the Transferred Subsidiaries taken as a whole other than coverage
mandated by applicable Law. The consummation of the transactions contemplated by this Agreement
will not (i) entitle any current or former employee or officer of a Transferred Subsidiary to
severance pay, unemployment compensation or any other payment or (ii) accelerate the time of
payment or vesting, or increase the amount of, any compensation due any such employee or officer.

(d) Each Employee Benefit Plan of a Transferred Subsidiary that is subject to the Laws of a
non-U.S. jurisdiction is in substantial compliance with the applicable Laws of that jurisdiction.

SECTION 3.15 Intellectual Property. Schedule 3.15 sets forth a listing of all
Intellectual Property Rights held or used by any Transferred Subsidiary, other than Intellectual
Property Rights related to (a) commercial off-the-shelf Software having a cost of less than One
Thousand United States Dollars (US$1,000) per seat or license and (b) standard form non-exclusive
licenses that are generally available and have a cost of less than Fifty Thousand United States
Dollars (US$50,000) per year (the “Transferred Subsidiary Intellectual Property Rights”). Except
for off-the-shelf software programs (including but not limited to word processing and spreadsheet
programs) and except as set forth on Schedule 3.15, each Transferred Subsidiary owns or
has a right to use all the Transferred Subsidiary Intellectual Property Rights held or used by it
free and clear of any Liens, other than Permitted Liens, and free from any requirement of any
past, present or future royalty payments, license fees, charges or other payments. Except as set
forth on Schedule 3.15, (a) no proceedings are pending or, to the Knowledge of Seller
threatened, which challenge the validity of the ownership or use by any Transferred Subsidiary of
any Transferred Subsidiary Intellectual Property Rights, (b) Seller has no Knowledge of any
infringement or infringing use of any Transferred Subsidiary Intellectual Property Rights or
licenses thereof by any Person and (c) to the Knowledge of Seller, no material infringement by
Seller or any of its Subsidiaries of any Intellectual Property Rights of any third party has
occurred in connection with the conduct of the Transferred Subsidiaries’ respective businesses or
will result in any way from the signing and execution of this Agreement or any of the Seller
Ancillary Documents or the consummation of any or all of the transactions contemplated hereby and
thereby, and no claim has been made by any third party based upon an allegation of any such
infringement. To the Knowledge of Seller, none of the former or present employees, officers or
directors of Seller or any of its Subsidiaries holds any right, title or interest, directly or
indirectly, in whole or in part, in or to any Transferred Subsidiary Intellectual Property
Rights. Neither Seller nor any of Seller’s Subsidiaries licenses from any present or, to
Seller’s Knowledge, former employees, officers or directors of Seller or any of Seller’s
Subsidiaries, any Transferred Subsidiary Intellectual Property Rights which are necessary for the
conduct of the business of the Transferred Subsidiaries. Except for agreements imposing an
obligation on former or present employees, officers, directors, or independent contractors of
Seller or any of Seller’s Subsidiaries to keep the Transferred Subsidiary Intellectual Property
Rights confidential or to assign to Seller or any of Seller’s Subsidiaries any Transferred
Subsidiary Intellectual Property Rights created, developed or conceived by any such Persons,
neither Seller nor any of Seller’s Subsidiaries is a party to any employment contract, patent
disclosure agreement or any other contract, agreement or arrangement with any employee of Seller
or any of Seller’s Subsidiaries relating to any Transferred Subsidiary Intellectual Property
Rights, that grants such employee an ownership right or other economic interest in such
Transferred Subsidiary Intellectual Property Rights.

assignments, waivers and authorizations or other certificates from third parties, including
Governmental Entities, and give such notices to third parties, including Governmental Entities, in
each case that are required to consummate the transactions provided for herein and to keep in
effect and avoid the breach, violation or termination of any Material Contract of any Transferred
Subsidiary (each, an “Assignment Consent”); provided, however, that reasonable
efforts by Seller shall not include (a) the payment of any amounts by Seller to any such third
party or (b) the amendment of any provision of, or waiver of any rights under, any contract between
Seller or any Transferred Subsidiary, on the one hand, and any such third party, on the other hand.
If any Assignment Consents are not received on or before the Closing Date with respect to any
Material Contract, Seller shall cooperate with Buyer in any reasonable arrangement designed to
provide Buyer with all of the benefits of such Material Contract as if the Assignment Consent had
been obtained as set forth in more detail in the Transition Services Agreement, including by
granting subleases and establishing subcontracting arrangements. In no event will Buyer be
entitled to delay the Closing or terminate this Agreement due to Seller’s failure to obtain an
Assignment Consent.

(g) For a period of four (4) years following the Closing Date, Seller hereby agrees not to,
either on its own account or in conjunction with or on behalf of any Person, carry on or be
engaged, directly or indirectly, whether as a shareholder, director, employee, partner, agent or
otherwise, in Europe, the Middle East or Africa in the delivery of the following services, whether
directly or as a subcontractor to an equipment vendor or any other Person, relating to wireless

by a Governmental Entity: (1) consulting services for all planning, including without limitation

Seller shall in no way be restricted for engaging in or carrying on such activities for
Governmental Entities through its WFI Government Services, Inc. entity in connection with the
non-commercial activities of such Governmental Entities, such as, but not limited to, military and
police functions. While the restrictions contained in this Section 5.1(f) are considered
by the parties to be reasonable in all the circumstances for the protection of the interests of
Buyer and/or the Transferred Subsidiaries, it is recognized that restrictions of the nature in
question may fail for technical reasons and, accordingly, it is hereby agreed and declared that if
any of such restrictions shall be adjudged to be void but would be valid if part of the wording
thereof were deleted or the periods thereof reduced or the range of activities or area dealt with
thereby reduced in scope, the said restriction shall apply with such modifications as may be
necessary to make it valid and effective. The parties hereby agree that any remedy at Law for any
of breach by Seller of any of the provisions contained in this Section 5.1(f) may be
inadequate and that Buyer will be entitled to seek injunctive relief in addition to any other
remedy Buyer may have under this Agreement.

necessary or appropriate to permit Buyer to (i) determine any matter relating to Buyer’s rights and
obligations hereunder, (ii) complete and/or initiate any and all financial audits necessary or
appropriate for Buyer’s business, operations and financial reporting purposes, and (ii) respond to,

the operation of the Transferred Subsidiaries prior to the Closing Date; provided,
however, that any such access by Buyer shall not unreasonably interfere with the conduct of
Seller’s business; provided, further that Buyer may retain copies of such books and records
that are reasonably necessary or appropriate to respond to, prepare for, or produce such
properties, books, records and employees in connection with any existing third-party or
governmental investigation, inquiry, action, suit, proceeding, claim or threatened or actual legal
proceeding or arbitration..

proceeding, claim or threatened or actual legal or arbitral proceedings, including, without
limitation, any and all stockholder derivative and/or class action litigation and inquiries and
investigations by the U.S. Securities and Exchange Commission (the “SEC”), whether or not in
existence as of the Closing Date; provided, however, that any such access by Seller
shall not unreasonably interfere with the conduct of the business of Buyer; provided,
further that Seller may retain copies of such books and records that are reasonably necessary or
appropriate to respond to, prepare for, or produce such properties, books, records and employees in
connection with any existing third-party or governmental investigation, inquiry, action, suit,
proceeding, claim or threatened or actual legal proceeding or arbitration.

(b) Without limiting the foregoing, Buyer will, and shall cause the Transferred Subsidiaries
to, provide full cooperation with respect to issues relating to, arising under or resulting from
Seller’s ongoing stockholder derivative and/or class action litigation and SEC investigation,
including, without limitation: (x) assisting in making employees of Buyer and the Transferred
Subsidiaries reasonably available for deposition testimony; and (y) preserving and delivering
original copies of, and providing reasonable access to, any and all properties, books, records,
documents relating to, arising under or resulting from Seller’s ongoing stockholder derivative
and/or class action litigation and SEC investigation. Seller shall be responsible for all
reasonable out-of-pocket costs incurred by Buyer and its Subsidiaries in complying with this
Section 5.2(b), including copying, delivery and telephone charges and shall provide Buyer
with reasonable compensation for the salary and benefits associated with any employees who devote a
significant portion of any calendar year assisting Seller pursuant to this Section 5.2(b).

SECTION 5.3 Mutual Covenants. Buyer and Seller agree that:

(a) Subject to the terms and conditions of this Agreement, Buyer and Seller will use
commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to
be done, all things necessary or desirable under applicable Laws to consummate the transactions
contemplated by this Agreement, including, without limitation, diligently pursuing the registration
of the transfer of the Equity Interests with the appropriate national, state, local or municipal
governmental authorities. Buyer agrees to cause the Transferred Subsidiaries to execute, notarize
and deliver such other documents, certificates, agreements and other writings and to take such
other actions as may be necessary or desirable in order to consummate or implement expeditiously
the transactions contemplated by this Agreement. Notwithstanding the foregoing, no delay,
postponement, or rejection of the registration of the transfer of the Equity Interests from Seller
to Buyer by any national, state, local or municipal governmental authority shall be deemed to delay
the Closing hereunder, and the parties shall take all reasonably necessary actions to effect such
registration of the transfer of the Equity Interests with the appropriate national, state, local or
municipal governmental authorities.

(b) Seller and Buyer shall cooperate with one another (i) in determining whether any action by
or in respect of, or filing with, any Governmental Entity is required or any actions, consents,
approvals or waivers are required to be obtained from parties to any material contracts, in each
case in connection with the consummation of the transactions contemplated by this Agreement, and
(ii) in taking such actions or making any such filings, furnishing information required in
connection therewith and seeking timely to obtain any such actions, consents, approvals or waivers.

(c) Buyer and Seller shall enter into a Transition Services Agreement, attached hereto as
Exhibit B, which Transition Services Agreement will, among other things, grant to Buyer a
license to use the name, trademarks and domain names related to “WFI” or Wireless Facilities” for
one hundred twenty (120) days following Closing pursuant to the terms and conditions contained
therein. The Transition Services Agreement shall also address identified IT support for the periods
specified therein and the cost to Buyer of such support.

(d) Unless the parties otherwise mutually agree in writing, Seller agrees that it will not,
and will not permit its Affiliates to, prior to the second anniversary of the Closing Date, in any
manner, directly or indirectly or by assisting others, (a) hire or attempt to hire, on any of their
behalves or on behalf of any other Person, any employee of any Transferred Subsidiary, or
(b) otherwise encourage any employee of a Transferred Subsidiary to leave the employ of Buyer;
provided, however, nothing in this Section 5.3(d) shall prohibit or prevent
Seller or its Affiliates from hiring or attempting to hire any employee of a Transferred Subsidiary
whose employment with a Transferred Subsidiary has been terminated and who has not been employed by
any Transferred Subsidiary for a period of six (6) or more months. Unless the parties otherwise
mutually agree in writing, the parties agree that they will not, and they will not permit their
Affiliates to, prior to the second anniversary of the Closing Date, in any manner, directly or
indirectly, or by assisting others, solicit or attempt to solicit on any of their behalves or on
behalf of any other Person any employee of the other party or its Affiliates, except that Buyer or
any of its Affiliates are permitted to continue to employ the employees of the Transferred
Subsidiaries following the Closing and that nothing in this Section 5.3(d) shall prohibit
or prevent the parties or their Affiliates from soliciting or attempting to solicit on any of their
behalves or on behalf of another Person any employee of the other party or its Affiliates where the
individual’s employment with the other party or its Affiliates has been terminated and such
individual has not been employed by the other party or its Affiliates for a period of six (6) or
more months. The foregoing provisions will not apply to general solicitations of potential
employees (e.g., general newspaper advertisements or website job postings) that are not
specifically targeted to the employees of the other party or otherwise intended to circumvent the
provisions of this Section 5.3(d). The parties hereby agree that any remedy at law for any
breach of the provisions contained in this Section 5.3(d) may be inadequate and that the
non-breaching party will be entitled to seek injunctive relief in addition to any other remedy such
party might have under this Agreement.

appeals from adverse determinations) or (ii) the payment of Tax by Buyer, Seller or any of their
Affiliates, whichever is responsible for payment of such Tax under applicable Law, with respect to

respect to state, local, or foreign Taxes, the consolidated, combined or unitary group of which
Seller or any of its Affiliates (other than any of the Transferred Subsidiaries) is a member and

the Treasury Regulations promulgated thereunder) or report, claims for refund, amended return and
declaration of estimated Tax.

SECTION 6.2 Liability for Taxes.

(a) “Indemnified Taxes” means (1) all Taxes of each of the Transferred Subsidiaries and their
respective assets or businesses for all Pre-Closing Tax Periods or allocable to Pre-Closing Partial
Tax Periods under the principles of Section 6.2(c); (2) all Taxes imposed on any
Transferred Subsidiary by reason of its inclusion during any period before the Closing in any group
of entities that filed or was or will be required to file Tax Returns on an affiliated,
consolidated, combined or unitary group basis (including Taxes imposed pursuant to Treasury
Regulations Section 1.1502-6 or any analogous or similar state, local, or foreign Law); (3) any and
all Taxes with respect to the Transferred Subsidiaries (and their respective assets or businesses)
resulting from or arising out of any of the transactions contemplated by this Agreement and not
effected in the ordinary course of business, other than Transfer Taxes allocable to Buyer pursuant
to Section 6.4(c); (4) any and all withholding Taxes collected from Buyer which are
determined by a relevant Governmental Entity to have been required to be withheld out of the
Purchase Price payable pursuant to this Agreement; (5) any and all Taxes resulting from or arising
out of the actions described in Section 5.1(c) or resulting from the Deed of Release or any
action taken pursuant to the Deed of Release for all Pre-Closing Tax Periods or allocable to
pre-Closing Partial Tax Periods under the principles of Section 6.2(c); (6) any and all
Taxes imposed on any Transferred Subsidiary as a transferee or successor of another Person, either
by contract or pursuant to any Law, to the extent that such transferee or successor liability for
Tax arose by reason of an event or transaction occurring at or prior to the Closing; and (7) any
and all Liabilities for Taxes with respect to any taxable period (whether before, during or after
the Closing Date), relating to or arising from matters described in Section 9.1(b)(iv),
including without limitation any Liabilities for Taxes arising from the provisions of the U.K.
Taxation of Chargeable Gains Act 1992, § 179 or the U.K. Finance Act 2002, Schedule 29, ¶ 58, other
than Liabilities incurred by reason of the breach by Buyer (and not by Seller) of the last sentence
of Section 6.9; provided, however, that Indemnified Taxes shall not include
the portion of any of the foregoing Taxes which is specifically identified as a liability on the
Unaudited Interim Balance Sheet or which is incurred in the ordinary course of business after
December 31, 2006 and not required under GAAP to be shown on the Unaudited Interim Balance Sheet.
For the avoidance of doubt, no indemnity is provided pursuant to Section 9.1(b) in respect
of Taxes for any Post-Closing Tax Period and any Straddle Period in excess of the portion allocable
to a Pre-Closing Partial Tax Period under the principles of Section 6.2(c) attributable to
unavailability or prior absorption of a loss carryover or similar Tax-related attribute from a
Pre-Closing Tax Period.

(b) “Non-Indemnified Taxes” means all Taxes which are not Indemnified Taxes, including without
limitation (1) all Taxes (or the non-payment thereof) of the Transferred Subsidiaries for all
Post-Closing Tax Periods and any Straddle Period in excess of the portion allocable to a
Pre-Closing Partial Tax Period under the principles of Section 6.2(c); and (2) all Taxes
imposed on any Transferred Subsidiary by reason of its inclusion during any period after the
Closing in any group of entities that file or is required to file Tax Returns on an affiliated,
consolidated, combined or unitary group basis (including Taxes imposed pursuant to Treasury
Regulations Section 1.1502-6 or any analogous provision of state, local, or foreign Law); and (3)
all Taxes imposed on any Transferred Subsidiary as a transferee or successor of another Person,
either by contract or pursuant to any Law, to the extent that such transferee or successor
liability for Tax arose by reason of an event or transaction occurring after the Closing.

(c) If the Transferred Subsidiaries are permitted but not required under applicable income Tax
Laws to treat the Closing Date as the last day of a taxable period, then the parties shall treat
that day as the last day of a taxable period. For purposes of this Section 6.2, in the
case of any Taxes that are payable for a Straddle Period, the portion of such Taxes that is
attributable to the Pre-Closing Partial Tax Period shall (1) subject to clause (2) of this
Section 6.2(c), including any Tax based on or measured by income or receipts of the
Transferred Subsidiaries during the Straddle Period, be deemed equal to the amount of Tax which
would be payable if the relevant taxable period had ended at the close of business on the Closing
Date and such Tax was computed on a “closing of the books” basis computed on a specific
identification basis, according to the date of the event or transaction giving rise to the Tax or
measure of Tax (with exemptions, allowances or deductions that are calculated on an annual or
periodic basis, such as the deduction for depreciation, apportioned on a pro-rata per diem basis);
provided, however, that, except as otherwise specifically provided in this
Agreement any Taxes attributable to (A) transactions not specifically contemplated by this
Agreement and not in the ordinary course of business that occur on the Closing Date but after the
Closing shall be considered to have occurred on the day following the Closing Date and (B)
transactions not specifically contemplated by this Agreement and not in the ordinary course of
business that occur on the Closing Date but before the Closing shall be considered to have occurred
on the day prior to the Closing Date, and (2) in the case of any other Tax with respect to which
the portion of which that is allocable to the Pre-Closing Partial Tax Period cannot practically be
determined on a specific identification basis (because of, for instance, restrictions imposed by
applicable Law) by reference to the “closing-of-the-books” method described above, be deemed to be
the amount of such Tax for the entire taxable period multiplied by a fraction, the numerator of
which is the number of days in the taxable period ending on the Closing Date, and the denominator
of which is the number of days in the entire taxable period. For avoidance of doubt, except as
otherwise provided in Section 6.4(c), Taxes imposed on the Transferred Subsidiaries as a
result of consummation on the Closing Date of the transactions contemplated by this Agreement shall
be allocated to the Pre-Closing Tax Period or Pre-Closing Partial Tax Period, as the case may be.

SECTION 6.3 Filing of Tax Returns.

(a) Seller will file (or cause to be filed) all Tax Returns of the Seller Group (collectively,
“Combined Tax Returns”) for all taxable periods in which any Transferred Subsidiary are included or
required to be included. Seller will prepare such Combined Tax Returns in a manner consistent with
past practice.

(b) Except as described in Sections 6.3.(a), Buyer shall prepare and timely file (or
cause to be timely filed) with the appropriate Taxing Authorities all Tax Returns required to be
filed by the Transferred Subsidiaries with respect to any taxable period beginning before the
Closing Date that are due after the Closing Date (each a “Buyer Prepared Return”). Each such Buyer
Prepared Return shall be prepared in a manner consistent with the prior practice of the Transferred
Subsidiaries, unless otherwise required by Law. Seller shall provide Buyer promptly any and all
information and documents reasonably requested by Buyer in connection with Buyer’s preparation of
such Buyer Prepared Returns. No liability in respect of Tax shown on any Buyer Prepared Return
shall be considered to constitute a Damage subject to indemnity pursuant to Section 9.1(b)
unless, before filing of such Buyer Prepared Return, Buyer shall have provided Seller with a copy
of such Buyer Prepared Return for review and comment and Seller shall have approved the filing of
such Buyer Prepared Return, which approval shall not be unreasonably withheld or delayed. For this
purpose, Seller’s withholding of approval of a Buyer Prepared Return based upon Buyer’s failure to
adopt in such Tax Return an alternative reporting position suggested by Seller in the notice of Tax
Statement Dispute described in Section 6.3(c) shall be deemed reasonable if the reporting
position proposed by the Seller to be reflected in such Buyer Prepared Return has a “reasonable
basis” (set forth in said notice), within the meaning of Section 6662 of the Code and is not
inconsistent with prior practice with respect to the Tax Returns of the relevant Transferred
Subsidiary. Buyer shall make a good faith effort to provide Seller with a copy of each such Buyer
Prepared Return for review and comment at least thirty (30) days prior to the required filing date
(with permitted extensions) of such return (or, if required to be filed within thirty (30) days
after the Closing or the end of the taxable period to which such return relates, as soon as
possible following the Closing or end of such taxable period, as the case may be), accompanied by a
statement (a “Pre-Closing Tax Statement”) setting forth and calculating in reasonable detail the
Indemnified Taxes that are shown as due on such Tax Return. Such Pre-Closing Tax Statement shall
be sufficient to allow Seller to make a reasonable determination as to the accuracy of the
calculation (except for inaccuracies which would not materially and adversely affect Seller). Each
Pre-Closing Tax Statement shall be considered to be a Notice of Claim within the meaning of
Section 9.5(a). Buyer shall timely pay or cause to be paid the Tax shown as due on each
Buyer Prepared Return, provided that such obligation shall not prevent recovery from Seller of any
portion thereof which constitutes Indemnified Taxes pursuant to Section 9.1.

(c) If Seller disagrees with the manner of preparation of a Buyer Prepared Return or the
amount of Indemnified Taxes calculated in the Pre-Closing Tax Statement, within ten (10) days of
the receipt of the Buyer Prepared Return and Pre-Closing Tax Statement, Seller shall provide to
Buyer a notice of such dispute (a “Tax Statement Dispute”). If Seller does not provide a notice of
Tax Statement Dispute within such 10-day period, the amount of Indemnified Tax shown therein shall
be treated as a Settled Claim, and the amount claimed therein shall be paid out of the Holdback
Amount as specified in Section 9.6.

(d) If Seller provides Buyer with a notice of a Tax Statement Dispute, Seller shall also
provide Buyer with a proposed revision of such Buyer Prepared Return, a statement setting forth and
calculating in reasonable detail the Indemnified Taxes with respect to such Buyer Prepared Return,
and a written explanation of the reasons for its adjustment. If Seller and Buyer, after
consultation with their tax advisors, cannot reach complete agreement, the dispute shall be
submitted to an arbitrator (the “Tax Arbitrator”) pursuant to the procedures described in
Section 10.6, for resolution by the Tax Arbitrator no later than five (5) days prior to the
required filing date of such Buyer Prepared Return. The decision of the Tax Arbitrator with
respect to such dispute shall be binding upon Buyer and Seller and their Affiliates. If a Tax
Statement Dispute is resolved such that the Tax reported as due on the applicable Buyer Prepared
Return is less than that proposed by Buyer in the applicable Pre-Closing Tax Statement, and the
Final Determination of any issue that was the subject of such Tax Statement Dispute results in
required payment of Indemnified Taxes, then, notwithstanding any other provision of this Agreement
to the contrary, Seller’s indemnification obligation under Section 9.1(b)(i) for the
portion of the resulting Indemnified Taxes which consist of penalties and interest payable in
respect of the portion of the Taxes determined to have been reportable in excess of the Taxes that
were initially proposed to be reported by Buyer in the Buyer Prepared Return shall be payable by
Seller as Damages without regard to the limitations otherwise applicable with respect to such
Damages under Sections 9.9 and 9.10 of this Agreement, and the amount of such interest and
penalties recoverable as Damages shall not be taken into account when applying the provisions of
Section 9.9 to indemnity obligations for other Damages .

(e) To the extent a Claim for Taxes set forth in a Pre-Closing Tax Statement that has been
Finally Determined within the meaning of Section 9.6, but cannot be fully satisfied out of
the Holdback Amount available at the time of such Final Determination, Seller shall pay to Buyer
the unsatisfied portion of the Finally Determined Claim for Taxes by wire transfer on the later of
(a) the third (3rd) Business Day prior to the due date for payment of such Taxes to the
relevant Taxing Authority and (b) the third (3rd) Business Day after such Claim was
Finally Determined.

SECTION 6.4 Tax Covenants.

(a) Upon the prior written request of Buyer, whether prior to or after the Closing Date,
Seller shall file (or to cause to be filed) or join (or cause one or more of their Affiliates to
join) in the execution and filing of an IRS Form 8832 and any other documentation necessary to
cause one or more of the Transferred Subsidiaries (other than WFIL and, if the action described in
clause (i) of Section 5.1(c) has been effectuated, WFI Sweden), as directed by Buyer, to
elect to be treated, effective as of the day prior to Closing, as a partnership or disregarded
entity for federal income tax purposes, as applicable; provided however, that notwithstanding
anything in this Agreement to the contrary, if such election is made as requested by Buyer, any Tax
Liability of such Transferred Subsidiary resulting from such election shall not be an Indemnified
Tax to the extent that it exceeds the Tax Liability that would have existed absent such election
with respect to such Transferred Subsidiary, and Buyer shall indemnify Seller and its Affiliates
from any adverse Tax consequences attributable to the making of such election; provided that, if
Buyer has given notice to Seller to make such election not less than fifteen (15) days before such
election is required to be filed, the amount of such indemnity shall be payable by Buyer only if
Seller has informed Buyer at least five (5) days before the required filing date for such election
of the nature and the reasonably estimated amount of such adverse Tax consequence and thereafter
promptly provided Buyer with such relevant information related to such adverse Tax consequences as
Buyer may reasonably request.

(b) Seller shall cause WFI UK, Ltd. to make the WFI Turkey Share Transfer Tax Filing no later
than one hundred sixty (160) days following the date of the transfer described in clause (iii) of
 Section 5.1(c) and promptly thereafter shall provide Buyer with evidence thereof.

(c) All transfer, documentary, sales, use, stamp, registration and other such fees and Taxes
(“Transfer Taxes”) incurred in connection with this Agreement and the cost of preparing any Tax
Returns related to Transfer Taxes shall be borne equally by Buyer and Seller. To the extent that
any portion of Transfer Tax is paid or required by Law to be paid by one party hereto but required
by the foregoing to be borne by another party hereto, such other party shall pay or reimburse the
Tax-paying party for the proper portion of the Tax required to be so borne upon notice from the
Tax-paying party of the amount of such Tax required to be paid or reimbursed. The parties shall
cooperate to file or cause to be filed all necessary Tax Returns and other documentation with
respect to all such Taxes.

SECTION 6.5 Contest Rights.

(a) If any party or any of its respective Affiliates receives notice or otherwise becomes
aware with respect to any (1) current or future audit, examination, investigation or other
proceeding or (2) any claim, demand, assessment (including a notice of proposed assessment), or
other assertion, in any case relating to Taxes relating to the Transferred Subsidiaries (or their
respective assets or businesses) that could give rise to a liability of the other party hereto
(including pursuant to Section 9.1), then such party, shall promptly notify the other party
in writing. Each party agrees to consult with and to keep the other party hereto informed on a
regular basis regarding the status of any Tax audit or proceeding. Seller and Buyer will
cooperate with each other (and cause their respective Affiliates to so cooperate) in the conduct of
any audit or other proceeding (including appeals) related to Taxes and all other Tax matters
relating to the Transferred Subsidiaries or their respective assets or businesses, and each will
execute and deliver such powers of attorney and other documents as are reasonably necessary to
carry out the intent of this Agreement. The party requesting cooperation under this Section
6.5(a) will reimburse the other party for any reasonable and actual out-of-pocket expenses
reasonably incurred in furnishing such cooperation.

(b) Subject to the other provisions of this Section 6.5, Seller shall have the right
to control, at its own expense, any and all audits and any and all subsequent proceedings with
respect to (i) any Pre-Closing Tax Period or Straddle Period which if adversely resolved, may
reasonably be expected to give rise to an Indemnified Tax, (ii) any taxable period reflected on a
Combined Tax Return, and (iii) solely for the sake of clarity, any Taxes solely of Seller or any of
its Affiliates (other than the Transferred Subsidiaries) not described in clauses (i) or (ii);
provided, however, that none of Seller or any of its Affiliates shall settle,
compromise, or waive or fail to initiate or pursue any such proceeding (or portion thereof) without
the specific prior written consent of Buyer if such settlement, compromise, waiver or failure
would cause any of Buyer or any of its Affiliates to be liable for Taxes (other than Indemnified
Taxes for which Buyer will be entitled to full and complete indemnification by Seller
notwithstanding the limitations contained in Section 9.9 and Section 9.10) for
which they would not have been liable absent such settlement, compromise, waiver or failure. Buyer
shall have the right to participate in such proceeding at its own expense, and shall be entitled to
control the disposition of any issue involved in such proceeding which does not affect a potential
liability of Seller. Both Buyer and Seller shall be entitled to represent their own interests in
light of their responsibilities (including indemnity obligations) for the related Taxes, at their
own expense, in any audit or administrative or judicial proceedings involving a Straddle Period.
Except as provided in this Section 6.5, the provisions of Article 9, including the
provisions therein addressing settlement authority, shall govern the manner in which any Tax audit
or administrative or judicial proceeding relating to Taxes is resolved.

SECTION 6.6 Tax Elections; Amended Returns; Refunds.

(a) Except in connection with an audit resolved pursuant to Section 6.5, no party or
Affiliate of a party may amend a Tax Return of a Transferred Subsidiary, or file or amend any Tax
election of a Transferred Subsidiary, in each case, with respect to a Pre-Closing Tax Period or
Pre-Closing Partial Tax Period without the consent of Seller, which consent shall not be
unreasonably withheld or delayed.

(b) To the extent any determination of Tax liability of a Transferred Subsidiary, whether as
the result of an audit or examination, a claim for refund, the filing of an amended Tax Return or
otherwise, results in any refund or credit of overpaid Indemnified Taxes, Buyer shall promptly pay
the amount of such refund or credit that is received or applied for the benefit of Buyer or its
Affiliates (but only to the extent that such overpaid Indemnified Taxes (i) have actually been
paid by Seller or any of the Transferred Subsidiaries (limited in the case of any Transferred
Subsidiary to payments made by such Transferred Subsidiary prior to Closing), either directly or
through indemnity payment to Buyer, and (ii) exceed any amount included as an asset in the
Unaudited Interim Balance Sheet in respect of a Transferred Subsidiary’s right to refund or credit
of such overpaid Indemnified Taxes), along with any interest actually received or credited
thereon, to Seller upon receipt thereof by Buyer or its Affiliates.

(c) Except as provided in Section 6.6(b), Buyer will be entitled to any refund (and
including interest paid therewith) of any Tax liability of the Transferred Subsidiaries.

SECTION 6.7 Treatment of Indemnification Payments. Any payment made by Buyer, Seller, or any
of their respective Affiliates pursuant to Article 9 shall, to the extent permissible under
applicable Law, be treated as an adjustment to the Purchase Price for all relevant Tax purposes.

SECTION 6.8 All Payments Net of Withholding. All payments made by Buyer (or any of its
Affiliates) to Seller (or any of its respective successors or assigns) pursuant to this Agreement
shall be made net of any amounts required to be withheld under applicable Law.

SECTION 6.9 Cooperation, Access to Information, and Record Retention. Seller and Buyer shall
cooperate, and cause their representatives and Affiliates to cooperate, as and to the extent
reasonably requested by the other party in connection with the filing of all Tax Returns, the
making of any election related to Taxes, the preparation for any audit by any Taxing Authority, and
the prosecution or defense of any claim, suit or proceeding (including appeals) relating to any
Taxes or Tax Return concerning or with respect to the Transferred Subsidiaries or their respective
assets or business. Such cooperation shall include the provision to the other party, upon request,
as promptly as practicable, of records and information which are reasonably relevant to any such
Tax Return, audit, litigation or other proceeding and making employees available on a mutually
convenient basis to provide additional information and explanation of any material provided
hereunder. The Seller and Buyer and their Affiliates shall (a) retain all books and records with
respect to Taxes of the Transferred Subsidiaries (including Tax Returns) relating to any taxable
period beginning before the Closing Date until the expiration of the statute of limitations for
assessment of Taxes for such respective taxable period, and (b) give the other party reasonable
written notice prior to transferring, destroying or discarding any such books and records and, if
another party so requests, allow such party to take possession of such books and records. The
parties further agree, (i) upon request, to use reasonable efforts to obtain any certificate or
other document from any Governmental Entity or any other Person as may be necessary to mitigate,
reduce or eliminate any Tax that could be imposed on the Transferred Subsidiaries or that could be
subject to indemnity pursuant to item 7 of Section 6.2(a); and (ii) except to the extent
contemplated by this Agreement or otherwise required by Law, to refrain from (and to cause their
Affiliates to refrain from) transferring any shares of stock in Questus or liquidating Questus
prior to January 1, 2009.

and all material declarations, filings and registrations with, any Governmental Entity, including
all necessary approvals under any applicable antitrust Laws, required to consummate the
transactions contemplated by this Agreement shall have been obtained or made, except to the extent
that the failure to obtain such consents, approvals, orders or authorizations or to make such
material declarations, filings or registrations would not reasonably be expected to have a Material
Adverse Effect on the Transferred Subsidiaries or Buyer (for purposes of this clause, after giving
effect to the transactions contemplated hereby); provided, however, that Buyer
shall be obligated to consummate the transactions contemplated by this Agreement, notwithstanding
the fact that the registration of the Equity Interests of the Transferred Subsidiaries may occur

forth in Article 3 must have been true and correct in all respects as of the date hereof

as of a specific date or dates, in which case such representations and warranties need only to be
true and correct on and as of such specified date or dates), except for inaccuracies of
representations or warranties the circumstances giving rise to which, individually or in the
aggregate, do not constitute and would not reasonably be expected to have a Material Adverse Effect
on the Transferred Subsidiaries (it being understood that, for purposes of determining the accuracy
of such representations and warranties, all “Material Adverse Effect” qualifications and other
materiality qualifications contained in such representations and warranties shall be disregarded),
and Buyer shall have received a certificate signed by a duly authorized officer of Seller to the
foregoing effect.

ARTICLE 9

INDEMNIFICATION

SECTION 9.1 Indemnification.

(a) Buyer and its Affiliates hereby agree to indemnify Seller and its officers, directors,
employees, attorneys, Subsidiaries and Affiliates (all such Persons being collectively referred to
as the “Seller Indemnified Party”) against and to hold each of them harmless from any and all
damages, losses, liabilities and expenses (including reasonable expenses of investigation and
reasonable attorneys’ fees and expenses in connection with any action, suit or proceeding)
(“Damages”) incurred or suffered by any Seller Indemnified Party arising out of: (i) any Tax
imposed on any Transferred Subsidiary for all taxable periods (or the portion thereof) beginning
after the Closing Date (determined in accordance with Section 6.2(c)); (ii) the operation
of the business of the Transferred Subsidiaries on or after the Closing Date; (iii) any breach of
any representation or warranty of Buyer hereunder; and (iv) the fraud or willful misconduct of
Buyer or any of its Affiliates.

(b) Seller and its Affiliates hereby agree to indemnify Buyer and its officers, directors,
employees, attorneys, Subsidiaries and Affiliates (all such Persons being collectively referred to
as the “Buyer Indemnified Party”) against and to hold each of them harmless from any and all
Damages incurred or suffered by Buyer Indemnified Party arising out of (i) Indemnified Taxes as
defined in Section 6.2, (ii) any breach of any representation or warranty of Seller
hereunder, (iii) the fraud or willful misconduct of Seller or any of its Affiliates, or (iv)
provided that such Damages have not arisen from a breach by Buyer (and not by Seller) of its
obligations under the last sentence of Section 6.9, (A) any operations of Questus at or
prior to the Closing or (B) any transactions relating to the ownership of Questus or any
transactions to which Questus was a party or by which it or its assets were bound, in each case
that occurred at or prior to the Closing.

SECTION 9.2 Notice of Claim; Third Party Claims.

(a) The party seeking indemnification under this Article 9 (the “Indemnified Party”)
agrees to give prompt notice (a “Notice of Claim”) to the party against whom indemnity is sought
(the “Indemnifying Party”) of the assertion of any claim or the commencement of any suit, action or
proceeding (any such claim, suit, action or proceeding, a “Claim”) in respect of which indemnity
may be sought under Section 9.1 and will provide the Indemnifying Party with such
information relating thereto that the Indemnifying Party may reasonably request. Each Notice of
Claim will contain the following: (i) a statement that the Indemnified Party has incurred or
suffered Damages in an aggregate stated amount arising from such Claim (which amount may be the
amount of damages claimed by a third party in a Third Party Claim (as defined in
Section 9.2(b))); and (ii) a brief description, in reasonable detail (to the extent
reasonably available to the Indemnified Party), of the facts, circumstances or events giving rise
to the alleged Damages based on the Indemnified Party’s good faith belief thereof, including the
identity and address of any third-party claimant (to the extent reasonably available to the
Indemnified Party) and copies of any formal demand or complaint, the amount of Damages, the date
each such item was incurred or suffered and the specific nature of the breach to which such item is
related. The failure to promptly notify the Indemnifying Party shall not relieve the Indemnifying
Party of its obligations hereunder, except to the extent such failure shall have adversely
prejudiced the Indemnifying Party.

(b) Except as otherwise provided with respect to Tax matters addressed in Article 6,
the Indemnifying Party will have the right, within 10 calendar days after written notice delivered
to the Indemnified Party, to assume full responsibility for any Damages resulting from any Claim
asserted by any third party for which indemnification is available hereunder (a “Third Party
Claim”) and to assume the defense of such Third Party Claim, including the employment of counsel
reasonably satisfactory to the Indemnified Party and the payment of the fees and disbursements of
such counsel. If, however, the Indemnifying Party declines or fails to assume the defense of such
Third Party Claim on the terms provided above or to employ counsel reasonably satisfactory to the
Indemnified Party, in either case within such 10-day period, then the Indemnifying Party will pay
the reasonable fees and disbursements of counsel for the Indemnified Party as incurred. The party
that is defending a Third Party Claim (the “Defending Party”) will at all times use reasonable
efforts to keep the party that is not defending a Third Party Claim (the “Non-Defending Party”)
reasonably apprised of the status of the defense of any matter the defense of which the
Indemnifying Party has assumed and to cooperate in good faith with the Indemnified Party with
respect to the defense of any such matter.

(c) The Non-Defending Party will have the right to participate at its own expense in all
proceedings. Each party shall cooperate, and cause their respective Affiliates to cooperate, in
the defense or prosecution of any Third Party Claim and shall furnish or cause to be furnished such
records, information and testimony, and attend such conferences, discovery proceedings, hearings,
trials or appeals, as may be reasonably requested in connection therewith.

(d) The Defending Party shall obtain the prior written consent of the Non-Defending Party
(which shall not be unreasonably withheld) before entering into any settlement of such Third Party
Claim.

SECTION 9.3 Calculation of Damages. The amount of any Damages payable under Section
9.1 by the Indemnifying Party shall be net of any amounts recovered or recoverable by the
Indemnified Party under applicable insurance policies. The amount of Damages attributable to
Indemnified Taxes shall be reduced by any Tax benefit actually realized by the Indemnified Party
or its Affiliates by virtue of suffering such Damages and shall be increased by any Tax detriment
actually realized by the Indemnified Party or its Affiliates by virtue of receiving
indemnification pursuant to this Article 9. The amount of any Damages otherwise subject
to indemnification under Section 9.1 shall also be reduced to the extent of any
“Unanticipated Cash Benefit” actually realized by the Buyer within one year following the Closing
Date.  The Buyer shall be deemed to have an Unanticipated Cash Benefit to the extent that, within
one year following the Closing Date, the Buyer or its Affiliates (i) actually receives cash from
an asset that was not shown on the Unaudited Interim Balance Sheet but would have properly been
shown pursuant to GAAP, or (ii) actually realizes a reduction in cash outflow because the actual
amount of a Liability of a Transferred Subsidiary is less than that shown on the Unaudited
Interim Balance Sheet.

SECTION 9.4 Rights Independent of Prior Investigation. The right of each party to
indemnification, reimbursement or other remedy based upon any representations, warranties,
covenants and obligations of the other party herein shall not be affected by any investigation
conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time,
whether before or after the execution and delivery of this Agreement or the Closing Date, by such
party with respect to the accuracy or inaccuracy of or compliance with any representation,
warranty, covenant or obligation.

SECTION 9.5 Resolution of Notice of Claim. Each Notice of Claim delivered by an Indemnified
Party to an Indemnifying Party will be resolved as follows:

(a) With respect to a Claim that does not arise out of a Third Party Claim, if, within 20
calendar days after a Notice of Claim is received by the Indemnifying Party, the Indemnifying Party
does not contest such Notice of Claim in writing to the Indemnified Party as provided in
Section 9.5(b), then the Indemnifying Party will be conclusively deemed to have consented to the
recovery by the Indemnified Party of the full amount of the Damages specified in the Notice of
Claim and, without further notice, to have stipulated to the entry of a final judgment for damages
against the Indemnifying Party for such amount in any court having jurisdiction over the matter
where venue is proper. With respect to a Third Party Claim, if the Indemnifying Party assumes the
defense of such Third Party Claim on the terms provided in Section 9.2(b) and employs
counsel reasonably satisfactory to the Indemnified Party, then the Indemnifying Party will be
conclusively deemed to have consented to the recovery by the Indemnified Party of the full amount
of the Damages specified in the Notice of Claim and, without further notice, to have stipulated to
the entry of a final judgment for damages against the Indemnifying Party for such amount in any
court having jurisdiction over the matter where venue is proper.

(b) If, (i) with respect to a Claim that is not a Third Party Claim, the Indemnifying Party
delivers the notice specified in Section 9.5(a) within the 20-day period specified or (ii)
with respect to a Third Party Claim, the Indemnifying Party declines or fails to assume the defense
of such Third Party Claim on the terms provided in Section 9.2(b) or to employ counsel
reasonably satisfactory to the Indemnified Party, in either case within the 10-day period provided
in Section 9.2(b) (a Claim described in either of the foregoing clauses (i) and (ii), a
“Contested Claim”), then such Contested Claim will be resolved by either (iii) a written settlement
agreement executed by the Indemnifying Party and the Indemnified Party or (iv) in the absence of
such a written settlement agreement, by binding arbitration between Indemnifying Party and the
Indemnified Party in accordance with the terms and provisions of Section 10.6.

(c) If a Claim (including a Contested Claim) is settled by a written settlement agreement
executed by the Indemnifying Party and the Indemnified Party (a “Settled Claim”), then the parties
will resolve such Settled Claim as provided in such settlement agreement.

SECTION 9.6 Disposition of Holdback Amount. The Holdback Amount shall be distributed as
follows:

(a) Upon the Final Determination (as hereafter defined) of a Claim against any Seller
Indemnifying Party prior to the date that is the earlier of (i) March 31, 2008 and (ii) the date
that Buyer files its annual report on Form 10-K for the fiscal year ended December 31, 2007 with
the SEC (the “Final Holdback Date”), a portion of the Holdback Amount equal to the lesser of the
amount of the Claim as Finally Determined or the entire amount of the Holdback Amount shall be
retained by Buyer and shall no longer constitute part of the Holdback Amount.

(b) On the Final Holdback Date, (i) if there are no Claims pending against any Seller
Indemnifying Party, a portion of the Holdback Amount equal to the original amount of the Holdback
Amount minus any amount retained by Buyer pursuant to Section 9.6(a) shall be released to
Seller and (ii) if there are any Claims pending against any Seller Indemnifying Party, (A) a
portion of the Holdback Amount equal to the lesser of the aggregate amount of such pending Claims
and the remaining balance of the Holdback Amount as of such date shall not be released to Seller
and remain subject to the provisions of this Section 9.6 until such time as all such
Claims have been Finally Determined and (B) any remaining amount of the Holdback Amount after the
application of subclause (A) shall be released to Seller.

(c) Upon the Final Determination of any Claim referred to in Section 9.6(b), a portion
of the Holdback Amount equal to the lesser of the amount of the Claim as Finally Determined or the
entire amount of the Holdback Amount shall be retained by Buyer and shall no longer constitute part
of the Holdback Amount.

(d) Upon the Final Determination of the last remaining Claim referred to in Section
9.6(b), any remaining balance of the Holdback Amount after application of Section
9.6(b) to such Claim shall be released to Seller.

(e) For purposes of this Section 9.6, a Claim shall be deemed to be “Finally
Determined” if (i) the Claim is a Settled Claim or (ii) an arbitrator or court has rendered an
award or judgment of such payment in favor of Buyer Indemnified Party and such award or judgment is
not subject to appeal, or the time for filing an appeal therefrom has passed and no appeal has been
filed. Buyer shall pay Seller interest at the rate per annum equal to the rate payable on six (6)
month certificates of deposit available from Citibank on the Closing Date with respect to any
portion of the Holdback Amount released to Seller; such interest shall accrue from the Closing Date
through the date that such portion of the Holdback Amount is released to Seller.

SECTION 9.7 Assignment of Claims. If the Indemnified Party receives any payment from an
Indemnifying Party in respect of any Damages pursuant to Section 9.1 and the Indemnified
Party could have recovered all or a part of such Damages from a third party (a “Potential
Contributor”) based on the underlying Claim asserted against the Indemnifying Party, the
Indemnified Party shall assign such of its rights to proceed against the Potential Contributor as
are necessary to permit the Indemnifying Party to recover from the Potential Contributor the
amount of such payment, provided, however , that in the case of a Buyer
Indemnified Party, such Buyer Indemnified Party shall have no obligation to assigns such rights
if Buyer determines in its reasonable discretion that to do so would be detrimental to a material
relationship between Buyer or any of its Subsidiaries and such Potential Contributor.

SECTION 9.8 Claims Period. The representations and warranties of Seller and Buyer contained
in Article 3 and Article 4 of this Agreement, respectively, and claims for
indemnification for Damages under this Article 9 arising from breaches of such
representations and warranties will survive the Closing until the date that is fifteen (15)
months following the Closing Date; provided that, the representation and
warranties of Seller in Section 3.4 (Ownership of the Transferred Subsidiaries),
Section 3.12 (Taxes), Section 3.13 (Employees) and Section 3.14 (Benefit
Plans) and claims for Indemnified Taxes as defined in Section 6.2 shall survive until
thirty (30) days following the expiration of the applicable statute or similar period of
limitations (the “Claims Period”). Notwithstanding the foregoing, if, prior to the close of
business on the last day of the Claims Period, an Indemnifying Party is properly notified of a
claim for indemnity hereunder and such claim has not been finally resolved or disposed of at such
date, such claim will continue to survive and will remain a basis for indemnity hereunder until
such claim is finally resolved or disposed of in accordance with the terms hereof.

SECTION 9.9 Liability Cap. Subject to the provisions of the last sentence of Section
6.3(d) and the provisions of this Section 9.9 below, the maximum aggregate amount of
indemnity for Damages to which the Seller Indemnified Parties and the Buyer Indemnified Parties
may be entitled with respect to Claims under Section 9.1(a)(iii) and Section
9.1(b)(ii), respectively, shall be Seven Hundred Thousand United States Dollars (US$700,000)
(the “General Liability Cap”) and the maximum aggregate amount of indemnity for Damages to which
Buyer Indemnified Parties may be entitled with respect to Claims under Section 9.1(b)(i)
shall be Two Million United States Dollars (US$2,000,000) (the “Tax Liability Cap”);
provided, however, that amounts payable with respect to all Claims Finally
Determined in favor of any Buyer Indemnified Party (including those under the General Liability
Cap) shall be aggregated for the purposes of determining whether the Tax Liability Cap has been
met; provided further that there shall be no maximum limit on the amount of
indemnity for Damages (i) for Claims under Section 9.1(b)(i) for Indemnified Taxes
described in item 4 or item 7 of Section 6.2(a), (ii) for Claims under Section
9.1(b)(i) for Indemnified Taxes arising out of or relating to any action described in clauses
(i), (ii), (iv) or (v) of Section 5.1(c) or resulting from the Deed of Release or any
action taken pursuant to the Deed of Release or (iii) for Claims under Section
9.1(b)(iv), and Damages for such Claims shall not be taken into account when applying the
General Liability Cap or the Tax Liability Cap to Claims for other Damages. For the avoidance of
doubt, Claims for Indemnified Taxes that are described in both Section 9.1(b)(i) and
Section 9.1(b)(ii) shall be treated as described in Section 9.1(b)(i).

SECTION 9.10 Liability Thresholds. Subject to the provisions of the last sentence of
Section 6.3(d) and the provisions of this Section 9.10 below, neither Buyer, on
the one hand, nor Seller on the other hand, shall be liable to the other under Section
9.1(a)(i) or (iii) or Section 9.1(b)(i) and (ii), respectively, unless the total
amount of Damages with respect to all Claims Finally Determined against Buyer or Seller, as
applicable, exceeds Twenty-Five Thousand United States Dollars (US$25,000) (the “Basket Amount”),
and once the amount of Damages Finally Determined against Buyer or Seller, as applicable, in
respect of such Claims exceeds the Basket Amount, the Buyer or Seller, as applicable, shall be
entitled to recover the entire amount of the Damages so determined. The foregoing provision
shall not apply to any Damages (i) for Claims under Section 9.1(b)(i) for Indemnified
Taxes described in item 4 or item 7 of Section 6.2(a), (ii) for Claims under Section
9.1(b)(i) for Indemnified Taxes arising out of relating to actions described in clauses (i),
(ii), (iv) or (v) of Section 5.1(c) or resulting from the Deed of Release or any action
taken pursuant to the Deed of Release or (iii) for Claims under Section 9.1(b)(iv). For
the avoidance of doubt, Claims for Indemnified Taxes that are described in both Section
9.1(b)(i) and Section 9.1(b)(ii) shall be treated as described in Section
9.1(b)(i).

SECTION 9.11 Remedy. Except for any equitable relief, including injunctive relief or
specific performance, to which any party hereto may be entitled, from and after the date hereof,
the indemnification rights provided in this Article 9 will be the sole and exclusive
remedy of each Party hereto and each of their respective Affiliates and their officers,
directors, employees, stockholders, agents or representatives with respect to this Agreement, and
no Party shall be entitled to rescission of the Agreement; provided, however, the
foregoing will in no way limit the rights of an Indemnified Party for any fraud or intentional
misconduct by a party in connection with this Agreement, the documents executed in connection
herewith or the transactions contemplated hereby.

amendment, by each party to this Agreement, and in the case of a waiver, by the party against

with the law of the State of New York, without regard to the conflicts of law rules of such
state.

SECTION 10.6 Arbitration. Except with respect to matters described in Sections

interpretation or performance of this Agreement, with the exception of any claim for a temporary
restraining order or preliminary or permanent injunctive relief to enjoin any breach or
threatened breach hereof, such dispute shall be settled by a panel of three arbitrators with such
arbitration to be held in New York, New York, before JAMS/ENDDISPUTE or its successor and
pursuant to the JAMS Comprehensive Arbitration Rules and Procedures in effect at that time, and

Each party shall initially bear its own costs and legal fees associated with such

prevailing party in any such arbitration (not including, however, a party involved in an

other party the reasonable attorneys’ fees, costs and expenses incurred by such prevailing party
in connection with such arbitration.

The decision of the arbitrators shall be final, provided, however, that if either party is
dissatisfied with the a decision of less than a unanimous decision of the panel of arbitrators,
such dissatisfied party may appeal the final award in accordance with JAMS’ Optional Arbitration

ARTICLE II

THE COMMITMENT AND CREDIT EXTENSIONS

2.01 Revolving Loans.

Subject to the terms and conditions set forth herein, the Lender agrees to make loans (each
such loan, a “Revolving Loan”) to the Borrower in Dollars from time to time on any Business
Day during the Availability Period in an aggregate outstanding principal amount not to exceed
Revolving Commitment Amount then in effect. Within the limits of the Revolving Commitment, and
subject to the other terms and conditions hereof, the Borrower may borrow under this Section
2.01, prepay under Section 2.03, and reborrow under this Section 2.01.
Revolving Loans may be Base Rate Loans, Eurodollar Rate Loans or Eurodollar Daily Floating Rate
Loans, as further provided herein.

2.02 Borrowings, Conversions and Continuations of Loans.

(a) Each Borrowing, each conversion of Loans from one Type to the other, and each continuation
of Eurodollar Rate Loans shall be made upon the Borrower’s irrevocable notice to the Lender, which
may be given by telephone. Each such notice must be received by the Lender not later than 11:00
a.m. (i) three Business Days prior to the requested date of (A) any Borrowing of, conversion to or
continuation of, Eurodollar Rate Loans or (B) any conversion of (x) Base Rate Loans to Eurodollar
Daily Floating Rate Loans, (y) Eurodollar Rate Loans to Eurodollar Daily Floating Rate Loans or (z)
Eurodollar Rate Loans to Base Rate Loans, and (ii) on the requested date of any Borrowing of Base
Rate Loans or Eurodollar Daily Floating Rate Loan or of any conversion of Eurodollar Daily Floating
Rate Loans to Base Rate Loans. Each telephonic notice by the Borrower pursuant to this Section
2.02(a) must be confirmed promptly by delivery to the Lender of a written Loan Notice,
appropriately completed and signed by a Responsible Officer of the Borrower. Each Borrowing of,
conversion to or continuation of Loans shall be in a principal amount of $50,000 or a whole
multiple of $50,000 in excess thereof. Each Loan Notice (whether telephonic or written) shall
specify (i) whether the Borrower is requesting a Borrowing, a conversion of Loans from one Type to
the other, or a continuation of Eurodollar Rate Loans, (ii) the requested date of the Borrowing,
conversion or continuation, as the case may be (which shall be a Business Day), (iii) the principal
amount of Loans to be borrowed, converted or continued, (iv) the Type of Loans to be borrowed or to
which existing Loans are to be converted, and (v) if applicable, the duration of the Interest
Period with respect thereto. If the Borrower fails to specify a Type of a Loan in a Loan Notice or
if the Borrower fails to give a timely notice requesting a conversion or continuation, then the
applicable Loans shall be made as, or converted to, Base Rate Loans. Any such automatic conversion
to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with
respect to the applicable Eurodollar Rate Loans. If the Borrower requests a Borrowing of,
conversion to, or continuation of Eurodollar Rate Loans in any Loan Notice, but fails to specify an
Interest Period, it will be deemed to have specified an Interest Period of one month.

(b) After giving effect to all Loans, all conversions of Loans from one Type to the other, and
all continuations of Loans as the same Type, there shall not be more than 7 Interest Periods in
effect with respect to Revolving Loans.

2.03 Prepayments.

(a) Voluntary Prepayments of Loans. The Borrower may, upon notice from the Borrower
to the Lender, at any time or from time to time voluntarily prepay Revolving Loans in whole or in
part without premium or penalty; provided that (A) such notice must be received by the
Lender not later than 11:00 a.m. (1) three Business Days prior to any date of prepayment of
Eurodollar Rate Loans and (2) not later than on the date of prepayment of Base Rate Loans or
Eurodollar Daily Floating Rate Loans; and (B) any such prepayment shall be in a principal amount of
$50,000 or a whole multiple of $50,000 in excess thereof (or, if less, the entire principal amount
thereof then outstanding). Each such notice shall specify the date and amount of such prepayment
and the Type(s) of Loans to be prepaid and, if Eurodollar Rate Loans are to be prepaid, the
Interest Period(s) of such Loans. If such notice is given by the Borrower, the Borrower shall make
such prepayment and the payment amount specified in such notice shall be due and payable on the
date specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied by all
accrued interest on the amount prepaid, together with any additional amounts required pursuant to
Section 3.05.

(b) Mandatory Prepayments of Loans.

(i) Revolving Commitments. If for any reason the aggregate principal amount of
all Revolving Loans outstanding at any time exceeds the Revolving Commitment Amount, the
Borrower shall immediately prepay Revolving Loans in an aggregate amount equal to such
excess.

(ii) Dispositions and Involuntary Dispositions. The Borrower shall prepay the
Revolving Loans in an aggregate amount equal to 100% of the Net Cash Proceeds of all
Dispositions and Involuntary Dispositions to the extent such Net Cash Proceeds are not
reinvested in property that is useful in the business of the Borrower and its Subsidiaries
within 180 days of the date of such Disposition or Involuntary Disposition.

(iii) Equity Issuances. Immediately upon the receipt by the Borrower or any
Subsidiary of the Net Cash Proceeds of any Equity Issuance, the Borrower shall prepay the
Revolving Loans in an aggregate amount equal to 100% of such Net Cash Proceeds.

(iv) Application of Mandatory Prepayments. All amounts required to be paid
pursuant to this Section 2.03(b) shall be applied first to Base Rate Loans, then to
Eurodollar Daily Floating Rate Loans and then to Eurodollar Rate Loans in direct order of
Interest Period maturities. All prepayments under this Section 2.03(b) shall be
subject to Section 3.05, but otherwise without premium or penalty, and shall be
accompanied by interest on the principal amount prepaid through the date of prepayment.

2.04 Termination or Reduction of Revolving Commitment.

(a) Optional Reductions. The Borrower may, upon notice to the Lender, terminate the
Revolving Commitment, or from time to time permanently reduce the Revolving Commitment to an amount
not less than the outstanding amount of Revolving Loans; provided that (i) any such notice
shall be received by the Lender not later than 12:00 noon five (5) Business Days prior to the date
of termination or reduction and (ii) any such partial reduction shall be in an aggregate amount of
$1 million or any whole multiple of $1 million in excess thereof. All fees accrued with respect
thereto until the effective date of any termination of the Revolving Commitment shall be paid on
the effective date of such termination.

(b) Mandatory Reductions. The Revolving Commitment Amount shall be permanently
reduced in an amount equal to the amount of Net Cash Proceeds that is available to be applied to
the prepayment of Revolving Loans pursuant to Section 2.03(b)(ii) and (iii)
irrespective of the aggregate principal amount of all Revolving Loans outstanding at such time.

2.05 Repayment of Loans.

On the Maturity Date, the Borrower shall repay the aggregate principal amount of all Revolving
Loans outstanding on such date.

2.06 Interest.

(a) Subject to the provisions of subsection (b) below, (i) each Eurodollar Rate Loan shall
bear interest on the outstanding principal amount thereof for each Interest Period at a rate per
annum equal to the sum of the Eurodollar Rate for such Interest Period plus the Applicable
Rate, (ii) each Eurodollar Daily Floating Rate Loan shall bear interest on the outstanding
principal amount thereof from the applicable borrowing date at a rate per annum equal to the
Eurodollar Daily Floating Rate plus the Applicable Rate and (iii) each Base Rate Loan shall
bear interest on the outstanding principal amount thereof from the applicable borrowing date at a
rate per annum equal to the Base Rate plus the Applicable Rate.

(b) While any Event of Default exists, the Borrower shall pay interest on the principal amount
of all outstanding Obligations hereunder at a fluctuating interest rate per annum at all times
equal to the Default Rate to the fullest extent permitted by applicable Laws.

(c) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date
applicable thereto and at such other times as may be specified herein. Interest hereunder shall be
due and payable in accordance with the terms hereof before and after judgment, and before and after
the commencement of any proceeding under any Debtor Relief Law.

2.07 Fees.

On the Closing Date, the Borrower shall pay to the Lender a fee in the amount of $65,000 (the
"Upfront Fee”), which fee shall be fully earned when paid and shall be non-refundable for
any reason whatsoever.

2.08 Computation of Interest and Fees.

All computations of interest for Base Rate Loans when the Base Rate is determined by Bank of
America’s “prime rate” shall be made on the basis of a year of 365 or 366 days, as the case may be,
and actual days elapsed. All other computations of fees and interest shall be made on the basis of
a 360-day year and actual days elapsed (which results in more fees or interest, as applicable,
being paid than if computed on the basis of a 365-day year). Interest shall accrue on each Loan
for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for
the day on which the Loan or such portion is paid, provided that any Loan that is repaid on
the same day on which it is made shall, subject to Section 2.10(a), bear interest for one
day. Each determination by the Lender of an interest rate or fee hereunder shall be conclusive and
binding for all purposes, absent manifest error.

2.09 Evidence of Debt.

The Loans shall be evidenced by one or more accounts or records maintained by the Lender in
the ordinary course of business. The accounts or records maintained by the Lender shall be
conclusive absent manifest error of the amount of the Loans to the Borrower and the interest and
payments thereon. Any failure to so record or any error in doing so shall not, however, limit or
otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to
the Obligations. Upon the request of the Lender, the Borrower shall execute and deliver to the
Lender a promissory note, which shall evidence the Loans in addition to such accounts or records.
Each such promissory note shall be in the form of Exhibit 2.09(a) (a “Note”). The
Lender may attach schedules to its Note and endorse thereon the date, Type (if applicable), amount
and maturity of its Loans and payments with respect thereto.

2.10 Payments Generally.

All payments to be made by the Borrower shall be made without condition or deduction for any
counterclaim, defense, recoupment or setoff. Except as otherwise expressly provided herein, all
payments by the Borrower hereunder shall be made to the Lender at the Lending Office in Dollars and
in immediately available funds not later than 2:00 p.m. on the date specified herein. All payments
received by the Lender after 2:00 p.m. shall be deemed received on the next succeeding Business Day
and any applicable interest or fee shall continue to accrue. If any payment to be made by the
Borrower shall come due on a day other than a Business Day, payment shall be made on the next
following Business Day, and such extension of time shall be reflected on computing interest or
fees, as the case may be.

If at any time insufficient funds are received by and available to the Lender to pay fully all
amounts of principal, interest and fees then due hereunder, such funds shall be applied (i)
first, toward payment of interest and fees then due hereunder and (ii) second,
toward payment of principal then due hereunder.

ARTICLE III

TAXES, YIELD PROTECTION AND ILLEGALITY

3.01 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation
of the Loan Parties hereunder or under any other Loan Document shall be made free and clear of and
without reduction or withholding for any Indemnified Taxes or Other Taxes, provided that if
any Loan Party shall be required by applicable law to deduct any Indemnified Taxes (including any
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 Lender receives an amount equal to the sum it would have received had no
such deductions been made, (ii) such Loan Party shall make such deductions and (iii) such Loan
Party shall timely pay the full amount deducted to the relevant Governmental Authority in
accordance with applicable law.

(b) Payment of Other Taxes by the Loan Parties. Without limiting the provisions of
subsection (a) above, the Loan Parties shall timely pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.

(c) Indemnification by the Loan Parties. The Loan Parties shall indemnify the Lender,
within 30 days after demand therefor, for the full amount of any Indemnified Taxes or Other Taxes
(including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts
payable under this Section) paid by the Lender 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 Borrower by the Lender
shall be conclusive absent manifest error.

(d) Evidence of Payments. As soon as practicable after any payment of Indemnified
Taxes or Other Taxes by any Loan Party to a Governmental Authority, the Borrower shall deliver to
the Lender the original or a certified copy of a receipt issued by such Governmental Authority
evidencing such payment, a copy of the return reporting such payment or other evidence of such
payment reasonably satisfactory to the Lender.

3.02 Illegality.

If the Lender determines that any Law has made it unlawful, or that any Governmental Authority
has asserted that it is unlawful, for the Lender or its applicable Lending Office to make, maintain
or fund Eurodollar Rate Based Loans, or to determine or charge interest rates based upon the
Eurodollar Base Rate or the Eurodollar Daily Floating Base Rate, or any Governmental Authority has
imposed material restrictions on the authority of the Lender to purchase or sell, or to take
deposits of, Dollars in the London interbank market, then, on notice thereof by the Lender to the
Borrower, any obligation of the Lender to make or continue Eurodollar Rate Based Loans or to
convert Base Rate Loans to Eurodollar Rate Based Loans shall be suspended until the Lender notifies
the Borrower that the circumstances giving rise to such determination no longer exist. Upon
receipt of such notice, the Borrower shall, upon demand from the Lender, prepay or, if applicable,
convert all Eurodollar Rate Based Loans of the Lender to Base Rate Loans, either on the last day of
the Interest Period therefor, if the Lender may lawfully continue to maintain such Eurodollar Rate
Loans to such day, or immediately, if the Lender may not lawfully continue to maintain such
Eurodollar Rate Loans. Upon any such prepayment or conversion, the Borrower shall also pay accrued
interest on the amount so prepaid or converted.

3.0 Inability to Determine Rates.

(a) If the Lender determines that for any reason in connection with any request for a
Eurodollar Rate Loan or a conversion to or continuation thereof that (a) Dollar deposits are not
being offered to banks in the London interbank eurodollar market for the applicable amount and
Interest Period of such Eurodollar Rate Loan, (b) adequate and reasonable means do not exist for
determining the Eurodollar Base Rate for any requested Interest Period with respect to a proposed
Eurodollar Rate Loan, or (c) the Eurodollar Base Rate for any requested Interest Period with
respect to a proposed Eurodollar Rate Loan does not adequately and fairly reflect the cost to the
Lender of funding such Loan, the Lender will promptly notify the Borrower. Thereafter, the
obligation of the Lender to make or maintain Eurodollar Rate Loans shall be suspended until the
Lender revokes such notice. Upon receipt of such notice, the Borrower may revoke any pending
request for a Borrowing of, conversion to or continuation of Eurodollar Rate Loans or, failing
that, will be deemed to have converted such request into a request for a Borrowing of Base Rate
Loans in the amount specified therein.

(b) If the Lender determines that for any reason in connection with any request for a
Borrowing of or conversion to a Eurodollar Daily Floating Rate Loan that (a) Dollar deposits are
not being offered to banks in the London interbank eurodollar market for the applicable amount for
a period of one month, (b) adequate and reasonable means do not exist for determining the
Eurodollar Daily Floating Base Rate with respect to a proposed Eurodollar Daily Floating Rate Loan,
or (c) the Eurodollar Daily Floating Base Rate with respect to a proposed Eurodollar Daily Floating
Rate Loan does not adequately and fairly reflect the cost to the Lender of funding such Loan, the
Lender will promptly notify the Borrower. Thereafter, the obligation of the Lender to make or
maintain Eurodollar Daily Floating Rate Loans shall be suspended until the Lender revokes such
notice. Upon receipt of such notice, the Borrower may revoke any pending request for a Borrowing
of or conversion to Eurodollar Daily Floating Rate Loan or, failing that, will be deemed to have
converted such request into a request for a Borrowing of Base Rate Loans in the amount specified
therein.

	 	 	 	 	 
	3.04

	 	Increased Costs.
	 	

	 
	 	 	 	 
	 	 	 

	 
	 	 	 	 
	
 
	 	(a)
	 	Increased Costs Generally. If any Change in Law shall:
	
 
	 	 	 	 

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan,
insurance charge or similar requirement against assets of, deposits with or for the account
of, or credit extended by, the Lender (except any reserve requirement reflected in the
Eurodollar Base Rate);

(ii) subject the Lender to any tax of any kind whatsoever with respect to this
Agreement, or any Eurodollar Rate Based Loan made by it, or change the basis of taxation of
payments to the Lender in respect thereof (except for Indemnified Taxes or Other Taxes
covered by Section 3.01 and the imposition of, or any change in the rate of, any
Excluded Tax payable by the Lender); or

(iii) impose on the Lender or the London interbank market any other condition, cost or
expense affecting this Agreement or Eurodollar Rate Based Loans made by the Lender;

and the result of any of the foregoing shall be to increase the cost to the Lender of making
or maintaining any Eurodollar Rate Based Loan (or of maintaining its obligation to make any
such Loan), or to reduce the amount of any sum received or receivable by the Lender
hereunder (whether of principal, interest or any other amount) then, upon request of the
Lender, the Borrower will pay to the Lender such additional amount or amounts as will
compensate the Lender for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If the Lender determines that any Change in Law affecting
the Lender or any Lending Office of the Lender or the Lender’s holding company, if any, regarding
capital requirements has or would have the effect of reducing the rate of return on the Lender’s
capital or on the capital of the Lender’s holding company, if any, as a consequence of this
Agreement, the Revolving Commitment of the Lender or the Loans made by the Lender, to a level below
that which the Lender or the Lender’s holding company could have achieved but for such Change in
Law (taking into consideration the Lender’s policies and the policies of the Lender’s holding
company with respect to capital adequacy), then from time to time the Borrower will pay to the
Lender such additional amount or amounts as will compensate the Lender or the Lender’s holding
company for any such reduction suffered.

(c) Certificates for Reimbursement. A certificate of the Lender setting forth the
amount or amounts necessary to compensate the Lender or its holding company, as the case may be, as
specified in subsection (a) or (b) of this Section and delivered to the Borrower shall be
conclusive absent manifest error. The Borrower shall pay the Lender the amount shown as due on any
such certificate within 30 days after receipt thereof.

3.05 Compensation for Losses.

Upon demand of the Lender from time to time, the Borrower shall promptly compensate the Lender
for and hold the Lender harmless from any loss, cost or expense incurred by it as a result of:

(a) any continuation, conversion, payment or prepayment of any Loan other than a Base
Rate Loan or a Eurodollar Daily Floating Rate Loan on a day other than the last day of the
Interest Period for such Loan (whether voluntary, mandatory, automatic, by reason of
acceleration, or otherwise); or

(b) any failure by the Borrower (for a reason other than the failure of the Lender to
make a Loan) to prepay, borrow, continue or convert any Loan other than a Base Rate Loan or
a Eurodollar Daily Floating Rate Loan on the date or in the amount notified by the Borrower;

including any loss of anticipated profits and any loss or expense arising from the liquidation or
reemployment of funds obtained by it to maintain such Loan or from fees payable to terminate the
deposits from which such funds were obtained. The Borrower shall also pay any customary
administrative fees charged by the Lender in connection with the foregoing.

For purposes of calculating amounts payable by the Borrower to the Lender under this
Section 3.05, the Lender shall be deemed to have funded each Eurodollar Rate Loan made by
it at the Eurodollar Base Rate used in determining the Eurodollar Rate for such Loan by a matching
deposit or other borrowing in the London interbank eurodollar market for a comparable amount and
for a comparable period, whether or not such Eurodollar Rate Loan was in fact so funded.

3.06 Survival.

All of the Borrower’s obligations under this Article III shall survive termination of
the Revolving Commitment and repayment of all other Obligations hereunder.

ARTICLE IV

GUARANTY

4.01 The Guaranty.

Each of the Guarantors hereby jointly and severally guarantees to the Lender and each other
holder of Obligations as hereinafter provided, as primary obligor and not as surety, the prompt
payment of the Obligations in full when due (whether at stated maturity, as a mandatory prepayment,
by acceleration, as a mandatory cash collateralization or otherwise) strictly in accordance with
the terms thereof. The Guarantors hereby further agree that if any of the Obligations are not paid
in full when due (whether at stated maturity, as a mandatory prepayment, by acceleration, as a
mandatory cash collateralization or otherwise), the Guarantors will, jointly and severally,
promptly pay the same, without any demand or notice whatsoever, and that in the case of any
extension of time of payment or renewal of any of the Obligations, the same will be promptly paid
in full when due (whether at extended maturity, as a mandatory prepayment, by acceleration, as a
mandatory cash collateralization or otherwise) in accordance with the terms of such extension or
renewal.

Notwithstanding any provision to the contrary contained herein or in any other of the Loan
Documents, Swap Contracts or Treasury Management Agreements, the obligations of each Guarantor
under this Agreement and the other Loan Documents shall be limited to an aggregate amount equal to
the largest amount that would not render such obligations subject to avoidance under the Debtor
Relief Laws or any comparable provisions of any applicable state law.

4.02 Obligations Unconditional.

The obligations of the Guarantors under Section 4.01 are joint and several, absolute
and unconditional, irrespective of the value, genuineness, validity, regularity or enforceability
of any of the Loan Documents, Swap Contracts or Treasury Management Agreements, or any other
agreement or instrument referred to therein, or any substitution, release, impairment or exchange
of any other guarantee of or security for any of the Obligations, and, to the fullest extent
permitted by applicable law, irrespective of any other circumstance whatsoever which might
otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, it being
the intent of this Section 4.02 that the obligations of the Guarantors hereunder shall be
absolute and unconditional under any and all circumstances. Each Guarantor agrees that such
Guarantor shall have no right of subrogation, indemnity, reimbursement or contribution against the
Borrower or any other Guarantor for amounts paid under this Article IV until such time as
the Obligations have been paid in full and the Revolving Commitment has expired or terminated.
Without limiting the generality of the foregoing, it is agreed that, to the fullest extent
permitted by law, the occurrence of any one or more of the following shall not alter or impair the
liability of any Guarantor hereunder, which shall remain absolute and unconditional as described
above:

(a) at any time or from time to time, without notice to any Guarantor, the time for any
performance of or compliance with any of the Obligations shall be extended, or such
performance or compliance shall be waived;

(b) any of the acts mentioned in any of the provisions of any of the Loan Documents,
any Swap Contract or Treasury Management Agreement between any Loan Party and the Lender, or
any Affiliate of the Lender, or any other agreement or instrument referred to in the Loan
Documents, such Swap Contracts or such Treasury Management Agreements shall be done or
omitted;

(c) the maturity of any of the Obligations shall be accelerated, or any of the
Obligations shall be modified, supplemented or amended in any respect, or any right under
any of the Loan Documents, any Swap Contract or Treasury Management Agreement between any
Loan Party and the Lender or any Affiliate of the Lender, or any other agreement or
instrument referred to in the Loan Documents, such Swap Contracts or such Treasury
Management Agreements shall be waived or any other guarantee of any of the Obligations or
any security therefor shall be released, impaired or exchanged in whole or in part or
otherwise dealt with;

(d) any Lien granted to, or in favor of, the Lender as security for any of the
Obligations shall fail to attach or be perfected; or

(e) any of the Obligations shall be determined to be void or voidable (including,
without limitation, for the benefit of any creditor of any Guarantor) or shall be
subordinated to the claims of any Person (including, without limitation, any creditor of any
Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly waives diligence,
presentment, demand of payment, protest and all notices whatsoever, and any requirement that the
Lender exhaust any right, power or remedy or proceed against any Person under any of the Loan
Documents, any Swap Contract or any Treasury Management Agreement between any Loan Party and the
Lender or any Affiliate of the Lender, or any other agreement or instrument referred to in the Loan
Documents, such Swap Contracts or such Treasury Management Agreements, or against any other Person
under any other guarantee of, or security for, any of the Obligations.

4.03 Reinstatement.

The obligations of the Guarantors under this Article IV shall be automatically
reinstated if and to the extent that for any reason any payment by or on behalf of any Person in
respect of the Obligations is rescinded or must be otherwise restored by any holder of any of the
Obligations, whether as a result of any proceedings in bankruptcy or reorganization or otherwise,
and each Guarantor agrees that it will indemnify the Lender on demand for all reasonable costs and
expenses (including, without limitation, the fees, charges and disbursements of counsel) incurred
by the Lender in connection with such rescission or restoration, including any such costs and
expenses incurred in defending against any claim alleging that such payment constituted a
preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law.

4.04 Certain Additional Waivers.

Each Guarantor agrees that such Guarantor shall have no right of recourse to security for the
Obligations, except through the exercise of rights of subrogation pursuant to Section 4.02
and through the exercise of rights of contribution pursuant to Section 4.06.

4.05 Remedies.

The Guarantors agree that, to the fullest extent permitted by law, as between the Guarantors,
on the one hand, and the Lender, on the other hand, the Obligations may be declared to be forthwith
due and payable as provided in Section 9.02 (and shall be deemed to have become
automatically due and payable in the circumstances provided in said Section 9.02) for
purposes of Section 4.01 notwithstanding any stay, injunction or other prohibition
preventing such declaration (or preventing the Obligations from becoming automatically due and
payable) as against any other Person and that, in the event of such declaration (or the Obligations
being deemed to have become automatically due and payable), the Obligations (whether or not due and
payable by any other Person) shall forthwith become due and payable by the Guarantors for purposes
of Section 4.01. The Guarantors acknowledge and agree that their obligations hereunder are
secured in accordance with the terms of the Collateral Documents and that the Lender may exercise
remedies thereunder in accordance with the terms thereof.

4.06 Rights of Contribution.

The Guarantors agree among themselves that, in connection with payments made hereunder, each
Guarantor shall have contribution rights against the other Guarantors as permitted under applicable
law. Such contribution rights shall be subordinate and subject in right of payment to the
obligations of such Guarantors under the Loan Documents and no Guarantor shall exercise such rights
of contribution until all Obligations have been paid in full and the Revolving Commitment has
terminated.

4.07 Guarantee of Payment; Continuing Guarantee.

The guarantee in this Article IV is a guaranty of payment and not of collection, is a
continuing guarantee, and shall apply to all Obligations whenever arising.

Lender may be recorded by the Lender, and each of the parties hereto hereby consents to such
recording.

10.03 No Waiver; Cumulative Remedies.

No failure by the Lender to exercise, and no delay by any such Person in exercising, any
right, remedy, power or privilege hereunder shall operate as a waiver thereof; nor shall any single
or partial exercise of any right, remedy, power or privilege hereunder or under any other Loan
Document preclude any other or further exercise thereof or the exercise of any other right, remedy,
power or privilege. The rights, remedies, powers and privileges herein provided, and provided
under each other Loan Document are cumulative and not exclusive of any rights, remedies, powers and
privileges provided by law.

10.04 Expenses; Indemnity; and Damage Waiver.

(a) Costs and Expenses. The Loan Parties shall pay (i) all reasonable out-of-pocket
expenses incurred by the Lender and its Affiliates (including the reasonable fees, charges and
disbursements of counsel for the Lender), in connection with the preparation, negotiation,
execution, delivery 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) and (ii) all out-of-pocket
expenses incurred by the Lender (including the fees, charges and disbursements of any counsel for
the Lender), in connection with the enforcement or protection of its rights (A) in connection with
this Agreement and the other Loan Documents, including its rights under this Section, or (B) in
connection with the Loans made hereunder, including all such out-of-pocket expenses incurred during
any workout, restructuring or negotiations in respect of such Loans.

(b) Indemnification by the Loan Parties. The Loan Parties shall indemnify the Lender
(and any agent thereof) and each Related Party of the Lender (each such Person being called an
“Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses (including the fees, charges and disbursements of any
counsel for any Indemnitee), and shall indemnify incurred by any Indemnitee or asserted against any
Indemnitee by any third party or by the Borrower or any other Loan Party arising out of, in
connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan
Document or any agreement or instrument contemplated hereby or thereby, the performance by the
parties hereto of their respective obligations hereunder or thereunder or the consummation of the
transactions contemplated hereby or thereby, or, in the case of the Lender (and any agent thereof)
and its Related Parties only, the administration of this Agreement and the other Loan Documents,
(ii) any Loan or the use or proposed use of the proceeds therefrom, (iii) any actual or alleged
presence or release of Hazardous Materials on or from any property owned or operated by a Loan
Party or any of its Subsidiaries, or any Environmental Liability related in any way to a Loan Party
or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or
proceeding relating to any of the foregoing, whether based on contract, tort or any other theory,
whether brought by a third party or by the Borrower or any other Loan Party, and regardless of
whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to
any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or
related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or
(y) result from a claim brought by the Borrower or any other Loan Party against an Indemnitee for
breach in bad faith of such Indemnitee’s obligations hereunder or under any other Loan Document, if
the Borrower or such Loan Party has obtained a final and nonappealable judgment in its favor on
such claim as determined by a court of competent jurisdiction.

(c) Waiver of Consequential Damages, Etc. To the fullest extent permitted by
applicable law, no Loan Party shall assert, and each Loan Party 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, the
transactions contemplated hereby or thereby, any Loan or the use of the proceeds thereof. No
Indemnitee referred to in subsection (b) above shall be liable for any damages arising from the use
by unintended recipients of any information or other materials distributed to such unintended
recipients by such Indemnitee through telecommunications, electronic or other information
transmission systems in connection with this Agreement or the other Loan Documents or the
transactions contemplated hereby or thereby other than for direct or actual damages resulting from
the gross negligence or willful misconduct of such Indemnitee as determined by a final and
nonappealable judgment of a court of competent jurisdiction.

(d) Payments. All amounts due under this Section shall be payable not later than 30
days after demand therefor that includes appropriate documentation of such expenses.

(e) Survival. The agreements in this Section shall survive the termination of the
Revolving Commitment and the repayment, satisfaction or discharge of all the other Obligations.

10.05 Payments Set Aside.

To the extent that any payment by or on behalf of any Loan Party is made to the Lender, or the
Lender exercises its right of setoff, and such payment or the proceeds of such setoff or any part
thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or
required (including pursuant to any settlement entered into by the Lender in its discretion) to be
repaid to a trustee, receiver or any other party, in connection with any proceeding under any
Debtor Relief Law or otherwise, then to the extent of such recovery, the obligation or part thereof
originally intended to be satisfied shall be revived and continued in full force and effect as if
such payment had not been made or such setoff had not occurred.

10.06 Successors and Assigns.

The provisions of this Agreement and the other Loan Documents shall be binding upon and inure
to the benefit of the parties hereto and thereto and their respective successors and assigns
permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights
or obligations hereunder or thereunder without the prior written consent of the Lender. The Lender
may at any time assign to one or more assignees all or a portion of its rights and obligations
under this Agreement and the other Loan Documents (including all or a portion of its Revolving
Commitment and the Loans at the time owing to it); provided that the consent of the
Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (1) an
Event of Default has occurred and is continuing at the time of such assignment or (2) such
assignment is to an Affiliate of the Lender or an Approved Fund. 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 and, to the extent expressly contemplated
hereby, the Related Parties of each of the Lender) any legal or equitable right, remedy or claim
under or by reason of this Agreement.

10.07 Treatment of Certain Information; Confidentiality.

The Lender agrees to maintain the confidentiality of the Information (as defined below),
except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’
respective partners, directors, officers, employees, agents, advisors and representatives and to
any direct or indirect contractual counterparty (or such contractual counterparty’s professional
advisor) under any Swap Contract relating to Loans outstanding under this Agreement (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 purporting to have jurisdiction over it
(including any self-regulatory authority, such as the National Association of Insurance
Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or
similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any
remedies hereunder or under any other Loan Document or any action or proceeding relating to this
Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f)
subject to an agreement containing provisions substantially the same as those of this Section, to
(i) any assignee of, or any prospective assignee of, any of its rights or obligations under this
Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or
derivative transaction relating to a Loan Party and its obligations, (g) with the consent of the
Borrower or (h) to the extent such Information (x) becomes publicly available other than as a
result of a breach of this Section or (y) becomes available to the Lender or any of its respective
Affiliates on a nonconfidential basis from a source other than the Borrower.

For purposes of this Section, “Information” means all information received from a Loan
Party or any Subsidiary relating to the Loan Parties or any Subsidiary or any of their respective
businesses, other than any such information that is available to the Lender on a nonconfidential
basis prior to disclosure by such Loan Party or any Subsidiary. 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.

The Lender acknowledges that (a) the Information may include material non-public information
concerning the Borrower or a Subsidiary, as the case may be, (b) it has developed compliance
procedures regarding the use of material non-public information and (c) it will handle such
material non-public information in accordance with applicable Law, including United States Federal
and state securities Laws.

10.08 Set-off.

If an Event of Default shall have occurred and be continuing, the Lender and each of its
Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted
by applicable law, to set off and apply any and all deposits (general or special, time or demand,
provisional or final, in whatever currency) at any time held and other obligations (in whatever
currency) at any time owing by the Lender or any such Affiliate to or for the credit or the account
of the Borrower or any other Loan Party against any and all of the obligations of the Borrower or
such Loan Party now or hereafter existing under this Agreement or any other Loan Document to the
Lender, irrespective of whether or not the Lender shall have made any demand under this Agreement
or any other Loan Document and although such obligations of the Borrower or such Loan Party may be
contingent or unmatured or are owed to a branch or office of the Lender different from the branch
or office holding such deposit or obligated on such indebtedness. The rights of the Lender and its
Affiliates under this Section are in addition to other rights and remedies (including other rights
of setoff) that the Lender or its Affiliates may have. The Lender agrees to notify the Borrower
promptly after any such setoff and application, provided that the failure to give such
notice shall not affect the validity of such setoff and application.

10.09 Interest Rate Limitation.

Notwithstanding anything to the contrary contained in any Loan Document, the interest paid or
agreed to be paid under the Loan Documents shall not exceed the maximum rate of non-usurious
interest permitted by applicable Law (the “Maximum Rate”). If the Lender shall receive
interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the
principal of the Loans or, if it exceeds such unpaid principal, refunded to the Borrower. In
determining whether the interest contracted for, charged, or received by the Lender exceeds the
Maximum Rate, such Person may, to the extent permitted by applicable Law, (a) characterize any
payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude
voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in
equal or unequal parts the total amount of interest throughout the contemplated term of the
Obligations hereunder.

10.10 Counterparts; Integration; Effectiveness.

This Agreement may be executed in counterparts (and by different parties hereto in different
counterparts), each of which shall constitute an original, but all of which when taken together
shall constitute a single contract. This Agreement and the other Loan Documents 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.
Except as provided in Section 5.01, this Agreement shall become effective when it shall
have been executed by the Lender and when the Lender shall have received counterparts hereof that,
when taken together, bear the signatures of each of the other parties hereto. 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.

10.11 Survival of Representations and Warranties.

All representations and warranties made hereunder and in any other Loan Document or other
document delivered pursuant hereto or thereto or in connection herewith or therewith shall survive
the execution and delivery hereof and thereof. Such representations and warranties have been or
will be relied upon by the Lender, regardless of any investigation made by the Lender or on their
behalf and notwithstanding that the Lender may have had notice or knowledge of any Default at the
time of any Borrowing, and shall continue in full force and effect as long as any Loan or any other
Obligation hereunder shall remain unpaid or unsatisfied.

10.12 Severability.

If any provision of this Agreement or the other Loan Documents is held to be illegal, invalid
or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this
Agreement and the other Loan Documents shall not be affected or impaired thereby and (b) the
parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable
provisions with valid provisions the economic effect of which comes as close as possible to that of
the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular
jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

10.13 Governing Law; Jurisdiction; Etc.

(a) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAW OF THE STATE OF NEW YORK.

10.14 Waiver of Right to Trial by Jury.

EACH PARTY HERETO HEREBY IRREVOCABLY 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 OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY
HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON 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.

10.15 ARBITRATION.

(a) This paragraph concerns the resolution of any controversies or claims between the parties,
whether arising in contract, tort or by statute, including but not limited to controversies or
claims that arise out of or relate to this or any other Loan Document (collectively a
"Claim”). For the purposes of this arbitration provision only, the term “parties” shall
include any parent corporation, subsidiary or affiliate of the Lender involved in the servicing,
management or administration of any obligation described or evidenced by this Agreement or any
other Loan Document.

(b) At the request of any party to this Agreement, any Claim shall be resolved by binding
arbitration in accordance with the Federal Arbitration Act (Title 9, U.S. Code) (the
"Act”). The Act will apply even though this Agreement provides that it is governed by the
law of a specified state. The arbitration will take place on an individual basis without resort to
any form of class action.

(c) Arbitration proceedings will be determined in accordance with the Act, the then-current
rules and procedures for the arbitration of financial services disputes of the American Arbitration
Association or any successor thereof (“AAA”), and the terms of this paragraph. In the
event of any inconsistency, the terms of this paragraph shall control. If AAA is unwilling or
unable to (i) serve as the provider of arbitration or (ii) enforce any provision of this
arbitration clause, the Lender may designate another arbitration organization with similar
procedures to serve as the provider of arbitration.

(d) The arbitration shall be administered by AAA and conducted, unless otherwise required by
law, in any U.S. state where real or tangible personal property collateral for this credit is
located or if there is no such collateral, in the state specified in the governing law section of
this Agreement. All Claims shall be determined by one arbitrator; however, if Claims exceed Five
Million Dollars ($5,000,000), upon the request of any party, the Claims shall be decided by three
arbitrators. All arbitration hearings shall commence within ninety (90) days of the demand for
arbitration and close within ninety (90) days of commencement and the award of the arbitrator(s)
shall be issued within thirty (30) days of the close of the hearing. However, the arbitrator(s),
upon a showing of good cause, may extend the commencement of the hearing for up to an additional
sixty (60) days. The arbitrator(s) shall provide a concise written statement of reasons for the
award. The arbitration award may be submitted to any court having jurisdiction to be confirmed,
judgment entered and enforced.

(e) The arbitrator(s) will give effect to statutes of limitation in determining any Claim and
may dismiss the arbitration on the basis that the Claim is barred. For purposes of the application
of the statute of limitations, the service on AAA under applicable AAA rules of a notice of Claim
is the equivalent of the filing of a lawsuit. Any dispute concerning this arbitration provision or
whether a Claim is arbitrable shall be determined by the arbitrator(s). The arbitrator(s) shall
have the power to award legal fees pursuant to the terms of this Agreement.

(f) This paragraph does not limit the right of any party to: (i) exercise self-help remedies,
such as but not limited to, setoff; (ii) initiate judicial or non-judicial foreclosure against any
real or personal property collateral; (iii) exercise any judicial or power of sale rights, or (iv)
act in a court of law to obtain an interim remedy, such as but not limited to, injunctive relief,
writ of possession or appointment of a receiver, or additional or supplementary remedies.

(g) The filing of a court action is not intended to constitute a waiver of the right of any
party, including the suing party, thereafter to require submittal of the Claim to arbitration.

10.16 No Advisory or Fiduciary Responsibility.

In connection with all aspects of each transaction contemplated hereby (including in
connection with any amendment, waiver or other modification hereof or of any other Loan Document),
each of the Loan Parties acknowledges and agrees, and acknowledges its Affiliates’ understanding,
that: (i) (A) the arranging and other services regarding this Agreement provided by the Lender are
arm’s-length commercial transactions between the Loan Parties and their respective Affiliates, on
the one hand, and the Lender, on the other hand, (B) each of the Loan Parties has consulted its own
legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate, and (C)
each of the Loan Parties is capable of evaluating, and understands and accepts, the terms, risks
and conditions of the transactions contemplated hereby and by the other Loan Documents; (ii) (A)
the Lender is and has been acting solely as a principal and, except as expressly agreed in writing
by the relevant parties, has not been, is not, and will not be acting as an advisor, agent or
fiduciary for the Loan Parties or any of their respective Affiliates, or any other Person and (B)
the Lender has no obligation to the Loan Parties or any of their respective Affiliates with respect
to the transactions contemplated hereby except those obligations expressly set forth herein and in
the other Loan Documents; and (iii) the Lender and its Affiliates may be engaged in a broad range
of transactions that involve interests that differ from those of the Loan Parties and their
respective Affiliates, and the Lender has no obligation to disclose any of such interests to the
Loan Parties and their respective Affiliates. To the fullest extent permitted by law, each of the
Loan Parties hereby waives and releases any claims that it may have against the Lender with respect
to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any
transaction contemplated hereby.

10.17 USA PATRIOT Act Notice.

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