ARTICLE 4

Net Share Settlement

     Section 4.01. Net Share Settlement. (a) The Calculation Agent shall determine the Final
Net Share Settlement Amount (as such term is defined below); provided that in no case shall Buyer
be required to deliver more than 16,000,000 Shares hereunder (subject to Section 8.01). For the
avoidance of doubt, the limitation contained in the proviso to the immediately preceding sentence
shall be absolute, and may not be overridden by Section 4.02 or any other provision of this
Agreement.

     (b) On the Settlement Date, Buyer shall deliver to Seller a number of Shares equal to the
Final Net Share Settlement Amount in compliance with the terms and conditions of Article 5.

     Section 4.02. Sale of Net Settlement Shares. (a) Seller, through the Selling Agent (as
defined below) or any underwriter(s), will sell all, or such lesser portion as may be required
hereunder, of the Shares comprising the Final Net Share Settlement Amount and any Additional Shares
(as defined below)
delivered by Buyer to Seller pursuant to Section 4.02(b) commencing on the Settlement Date and
continuing until the date on which the aggregate Net Proceeds (as such term is defined below) of
such sales, as determined by Seller, is equal to the Final Settlement Amount (such date, the “Final
Resale Date”). If the proceeds of any sale(s) made by Seller, the Selling Agent or any
underwriter(s), net of any fees and commissions (including, without limitation, underwriting or
placement fees) customary for similar transactions under the circumstances at the time of the
offering, together with carrying charges and expenses incurred in connection with the offer and
sale of the Shares (including, but without limitation to, the covering of any over-allotment or
short position (syndicate or otherwise)) (the “Net Proceeds”) exceed the Final Settlement Amount,
Seller will refund, in U.S. Dollars, such excess to Buyer on the date that is three (3) Business
Days following the Final Resale Date, and, if any portion of the Final Net Share Settlement Amount
remains unsold, Seller shall return to Buyer on that date such unsold Shares.

(b) If the Calculation Agent determines that the Net Proceeds received from the sale of Final Net
Share Settlement Amount or any Additional Shares (if any) pursuant to this Section 4.02 are less
than the Final Settlement Amount (the amount in U.S. Dollars by which the Net Proceeds are less
than the Final Settlement Amount being the “Shortfall” and the date on which such determination is
made, the “Deficiency Determination Date”), Buyer shall on the Exchange Business Day next
succeeding the Deficiency Determination Date (the “Makewhole Notice Date”) deliver to Seller a
notice of Buyer’s election that Buyer shall either (i) pay an amount in cash equal to the Shortfall
on the day that is one (1) Business Day after the Makewhole Notice Date, or (ii) deliver additional
Shares. For the avoidance of doubt, if Buyer has delivered the maximum number of shares specified
in the proviso to the first sentence of section 4.01, Buyer’s obligation is complete and there is
no further obligation for Buyer to deliver cash or shares. If Buyer elects to deliver to Seller
additional Shares, then Buyer shall deliver additional Shares in compliance with the terms and
conditions of Article 5 (the “Additional Shares”) on the first Clearance System Business Day which
is also an Exchange Business Day following the Makewhole Notice Date in such number as the
Calculation Agent reasonably believes would have a market value on that Exchange Business Day equal
to the Shortfall. Such Additional Shares shall be sold by Seller in accordance with the provisions
above; provided that if the sum of the Net Proceeds from the sale of the originally delivered
Shares and the Net Proceeds from the sale of any Additional Shares is less than the Final
Settlement Amount then Buyer shall, at its election, either make such cash payment or deliver to
Seller further Additional Shares until such Shortfall has been reduced to zero. If the sum of the
Net Proceeds from the sale of the originally delivered Shares and the Net Proceeds from the sale of
any Additional Shares exceeds the Final Settlement Amount, then Seller will refund, in U.S.
Dollars, such excess to Buyer on the date that is three (3) Business Days following the relevant
Final Resale Date and, if any portion of the Final Net Share

5

 

Settlement Amount or the Additional
Shares remains unsold, Seller shall return to Buyer on the date that is two (2) Business Days
following the Final Resale Date such unsold Shares.

     Section 4.03. Additional Definitions. For the purposes of the Transaction:

“Final Net Share Settlement Amount” means the number of Shares, rounded up to the nearest
whole one hundred (100) Shares, determined by the Calculation Agent to be equal to, if Net Share
Settlement is applicable, the quotient of (x) the Net Share Settlement Percentage of the Final
Settlement Amount divided by (y) the Reference Price.

“Net Share Settlement Percentage” has the meaning set forth in Schedule I.

“Reference Price” means (i) in the case of a Registered Offering (defined below), the closing price
of the Shares on the Exchange on the Exchange Business Day immediately proceeding the Settlement
Date, or (ii) in the case of an Exempt Offering, such closing price minus a discount for such
Shares pursuant to such Exempt Offering determined by the Calculation Agent in a commercially
reasonable manner.

ARTICLE 5

Offering Method

     Section 5.01. Offering Method. Buyer shall determine whether the offering method (the
“Offering Method”) by which Shares will be sold in respect of the Transaction will be pursuant to a
registration statement filed pursuant to the Securities Act and in a manner which otherwise
satisfies the terms and conditions of Appendix A hereto (a “Registered Offering”) or pursuant to an
offering that is exempt from the registration requirements of the Securities Act (an “Exempt
Offering”).

     Section 5.02. Condition Precedent to Electing Registered Offering. It shall be a condition
precedent to Buyer’s election of a Registered Offering that Buyer shall have filed a registration
statement that has been declared effective by the Securities and Exchange Commission (the
“Commission”) and that complies with Appendix A hereto. To the extent required to effect such
Registered Offering, Seller will use its reasonable efforts, and shall use reasonable efforts to
cause each Selling Agent engaged by Seller and any underwriter(s)), to co-operate with Buyer in
order to comply in all material respects with Appendix A hereto. A “Selling Agent” shall mean a
broker dealer registered with the Commission under Section 15 of the Exchange Act; the Selling
Agent may also be an underwriter for purposes of this Article 5.

     Section 5.03. Condition Precedent to Electing Exempt Offering. If Buyer elects an Exempt
Offering as the Offering Method, it agrees to comply with the reasonable requests of Seller, the
Selling Agent, any placement agent, if any, and any purchaser of the Shares; and shall either (A)
represent that it is not aware of any material non-public information regarding the Buyer or the
Shares as of the date it elects an Exempt Offering, or (B) before purchasers decide to purchase the
Shares, enter into a confidentiality agreement relating to any material non-public information
regarding the Buyer or the Shares with such purchasers. If Buyer has elected an Exempt Offering as
the Offering Method, Seller agrees to use commercially reasonable means to effect such Exempt
Offering at commercially reasonable prices in light of the market conditions and the circumstances
of Buyer at the time of the Exempt Offering. Buyer hereby acknowledges that any Shares sold
pursuant to an Exempt Offering may be sold at prices that represent a discount to the prices that
may otherwise be available if such Shares were to be sold pursuant to a registered public offering
or at prices observed in the secondary market.

     Section 5.04. Seller’s Obligations. Neither Seller nor any Selling Agent shall have any
obligation to commence any offer and sale of any Shares delivered by Buyer to Seller until,

	 	(a)	 	in the case of a Registered Offering,

6

 

          (i) each condition set forth in Appendix A hereto has been satisfied, or

          (ii) Seller, the Selling Agent and any underwriter(s) shall have completed any due diligence
investigations, made such inquiries and executed and delivered an underwriting agreement containing
customary representations, covenants, indemnities and contribution provisions and pursuant to
which, inter alia, Seller, the Selling Agent and any underwriter(s) shall have received such
letters, opinions, certificates or other documents, in form and substance satisfactory to Seller,
the Selling Agent and any underwriter(s), as such person(s) may require in light of the applicable
federal and state securities laws; or,

     (b) in the case of an Exempt Offer, such conditions as any purchasers or the Selling Agent, or
their respective counsel, may reasonably require.

ARTICLE 6

     Section 6.01. Representations and Warranties of Buyer and Seller. Each party hereto makes to
the other party hereto the representations and warranties contained in Sections 3(a) and 3(c) of

therein or necessary to make the statements therein, in the light of the circumstances in which

Transaction, will be duly authorized and validly issued, fully paid and nonassessable, and the
issuance thereof will not be subject to any preemptive or similar rights.

     (e) Buyer will reserve and keep available, free from preemptive rights, out of its authorized

     (f) Prior to the Settlement Date, any Shares to be delivered on the Settlement Date by Buyer

Exchange Act. Buyer has not entered into or altered any hedging transaction relating to the Shares
intended to correspond to or offset the Transaction.

     (k) Buyer is not engaged in a “distribution”, as such term is used in Regulation M, that would
preclude purchases by Buyer of Shares.

     (l) Buyer is an “eligible contract participant” as such term is defined in Section 1(a)(12) of

has been timely filed, any extensions shall be taken into account.

     Section 6.03. Representations and Warranties of Seller. Seller represents and warrants to

Covenants

     Section 7.01. Covenants of Buyer. Buyer hereby agrees with Seller to the following:

     (a) Without the prior written consent of Seller, Buyer shall not, and shall cause its
affiliates or affiliated purchasers (as defined in Rule 10b-18) not to, directly or indirectly
(including by means of a derivative instrument) enter into any transaction to purchase any Shares,
other than purchases from employees of Buyer, that are not “Rule 10b-18 purchases” as such term is
defined in Rule 10b-18, until its obligations under the Transaction have been satisfied in full.

     (b) Buyer shall, at least one day prior to the first day of the Valuation Period, notify
Seller of the total number of Shares purchased in Rule 10b-18 purchases of blocks pursuant to the
once-a-week block exception contained in Rule 10b-18(b)(4) by or for Buyer or any of its affiliated
purchasers during each of the four calendar weeks preceding the first day of the Valuation Period
and during the calendar week in which the first day of the Valuation Period occurs (“Rule 10b-18
purchase”, “blocks” and
“affiliated purchaser” each being used as defined in Rule 10b-18), which notice shall be
substantially in the form set forth as Annex B hereto.

     (c) Neither Buyer nor any of its affiliates shall take any action that would cause any Seller
Purchases not to meet the requirements of the safe harbor provided by Rule 10b-18 if such purchases
were made by Buyer.

     (d) On any day prior to the second Business Day immediately following the last day of the
Valuation Period, neither Buyer nor any of its affiliates or agents shall make a distribution (as
defined in Regulation M) of Shares, or any security for which the Shares are a reference security
(as defined in Regulation M) that would, in the view of Seller, preclude Buyer from purchasing
Shares or cause any such purchases to violate any law, rule or regulation, unless Buyer notifies
Seller of such distribution one Business Day prior to the beginning of the restricted period
applicable to such distribution under Regulation M. Buyer acknowledges that any such notice may
cause the Daily Reference Share Amount for any Valuation Date to be reduced. Accordingly, if such
notice is delivered during a Plan Period, if any, Buyer acknowledges that its actions in relation
to any such notice must comply with the standards set forth in Section 7.01(f).

     (e) Buyer shall not, at any time during a Plan Period, communicate, directly or indirectly,
any material nonpublic information concerning itself or the Shares to any Relevant Credit Suisse
Personnel. “Relevant Credit Suisse Personnel” means any employee of Seller or any affiliate,
except employees that Seller has notified Buyer in writing are not “Relevant Credit Suisse
Personnel”.

     (f) Buyer agrees that, during a Plan Period, Buyer shall not enter into or alter any hedging
transaction relating to the Shares intended to correspond to or offset the Transaction. Buyer also
acknowledges and agrees that any amendment, modification, waiver or termination of

9

 

this Agreement
must be effected in accordance with the requirements for the amendment or termination of a “plan”
as defined in Rule 10b5-1(c). Without limiting the generality of the foregoing, any such
amendment, modification, waiver or termination during a Plan Period shall be made in good faith and
not as part of a plan or scheme to evade the prohibitions of Rule 10b-5, and no such amendment,
modification, waiver or termination shall be made during a Plan Period at any time at which Buyer
or any officer, director, manager or similar person of Buyer is aware of any material non-public
information regarding Buyer or the Shares.

     (g) Buyer shall (i) notify Seller, subject to confidentiality, prior to the opening of trading
in the Shares on any day on which Buyer makes, or expects to be made, any public announcement (as
defined in Rule 165(f) under the Securities Act) of any merger, acquisition, or similar transaction
involving a recapitalization relating to Buyer (other than any such transaction in which the
consideration consists solely of cash and there is no valuation period), (ii) promptly notify
Seller following any such announcement that such announcement has been made, and (iii) promptly
deliver to Seller following the making of any such announcement a certificate indicating (A)
Buyer’s average daily Rule 10b-18 purchases (as defined in Rule 10b-18) during the three full
calendar months preceding the date of the announcement of such transaction and (B) Buyer’s block
purchases (as defined in Rule 10b-18) effected pursuant to paragraph (b)(4) of Rule 10b-18 during
the three full calendar months preceding the date of the announcement of such transaction. In
addition, Buyer shall promptly notify Seller of the earlier to occur of the completion of such
transaction and the completion of the vote by target shareholders. Buyer acknowledges that any
such public announcement may cause the Daily Reference Share Amount for any Valuation Date to be
reduced. Accordingly, Buyer acknowledges that its actions in relation to any such announcement or
transaction during a Plan Period must comply with the standards set forth in Section 7.01(f).

ARTICLE 8

Adjustment and Termination Events

     Section 8.01. Calculation Agent Adjustments. (a) In the event of any corporate event
involving Buyer or the Shares (including, without limitation, a stock split, stock dividend,
bankruptcy, insolvency, reorganization, merger, offer to tender Shares (whether such offer is made
by the Company or a third party, and whether the consideration for such offer is cash or non-cash),
rights offering, recapitalization, spin-off
or issuance of any securities convertible or exchangeable into Shares) or the announcement of
any such corporate event, the Calculation Agent may adjust the terms of the Transaction (including,
without limitation, the number of Valuation Dates in the Valuation Period, any Daily Adjustment
Price, any Daily Reference Share Amount and any Daily Difference) as it deems appropriate under the
circumstances to account for the economic effect on the Transaction of such corporate event
(including, without limitation, adjustments to account for changes in the price of the Shares or
changes in volatility, expected dividends, stock loan rate or liquidity relevant to the Shares as a
result of any such corporate event); provided that any adjustment shall not take into account a
party’s legal fees and out-of-pocket expenses.

     (b) Notwithstanding the authority provided to the Calculation Agent in subsection (a) of this
Section 8.01, in the event of a corporate event (such as certain reorganizations, mergers, or other
similar events) in which all holders of Shares may receive consideration other than the common
equity securities of the continuing or surviving entity, the adjustments referred to in such
subsection shall permit Buyer or Seller to satisfy its settlement obligations hereunder by
delivering the consideration received by holders of Shares upon such corporate event, in such
proportions as in the exercise of its good faith judgment the Calculation Agent deems appropriate
under the circumstances.

     Section 8.02. Termination Events. If one or more of the following events (each, a
“Termination Event”) shall occur:

10

or other similar law affecting creditors’ rights, or a petition is presented for its winding-up or
liquidation by it or such regulator, supervisor or similar official or it consents to such a
petition; (v) institutes or has instituted against it a proceeding seeking a judgment of insolvency
or bankruptcy or any other relief under any bankruptcy or insolvency law or other similar law
affecting creditors’ rights, or a petition is presented for its winding-up or liquidation (other

of any such proceeding or petition instituted or presented against it, such proceeding or petition
(A) results in a judgment of insolvency or bankruptcy or the entry of an order for relief or the
making of an order for its winding-up or liquidation or (B) is not dismissed, discharged, stayed or
restrained in each case within 15 days of the institution or presentation thereof; (vi) has a

Custodian for it or for all or substantially all its assets; (viii) has a secured party take
possession of all or substantially all its assets or has a distress, execution, attachment,
sequestration or other legal process levied, enforced or sued on or against all or substantially
all its assets and such secured party maintains possession, or any such process is not dismissed,
discharged, stayed or restrained, in each case within 30 days thereafter; (ix) is subject to any
voluntary or involuntary liquidation, bankruptcy, insolvency, dissolution or winding-up of or any
analogous proceeding as a result of which (A) all of the shares of Common Stock are required to be
transferred to a Custodian or (B) holders of the shares of Common Stock become legally prohibited
from transferring them; (x) causes or is subject to any event with respect to it which, under the
applicable laws of any jurisdiction, has an analogous effect to any of the events specified in
clauses (i) to (ix) (inclusive); or (xi) takes any action in furtherance of, or indicating its
consent to, approval of, or acquiescence in, any of the foregoing acts.

     (c) (i) any representation or warranty made by Buyer or Seller under this Agreement is
incorrect or misleading in any material respect or (ii) any certificate delivered by Buyer or
Seller pursuant to this Agreement is incorrect or misleading in any material respect;

     (d) Buyer or Seller fails to fulfill or discharge when due any of its obligations, covenants
or agreements under or relating to this Agreement (other than the obligations referred to in
Section 8.02(i) hereof) and such failure remains unremedied for 10 days following notice from
Seller or Buyer, as the case may be;

     (e) all of the Shares or all or substantially all the assets of Buyer are nationalized,
expropriated or are otherwise required to be transferred to any governmental agency, authority,
entity or instrumentality thereof;

     (f) the Exchange announces that pursuant to the rules of such Exchange, the Shares cease (or
will cease) to be listed, traded or publicly quoted on the Exchange for any reason (other than a
Merger Event or Tender Offer, as each such term is defined under the 2002 ISDA Equity Derivatives
Definitions, as published by the International Swaps and Derivatives Association, Inc.) and will
not be re-listed, re-traded or re-quoted on an exchange or quotation system located in the same
country as the Exchange (or, where the Exchange is within the European Union, in

11

 

any member state
of the European Union) within five Scheduled Trading Days of so ceasing to be so listed, traded or
quoted;

     (g) Seller is unable, after using commercially reasonable efforts, to (A) acquire, establish,
re-establish, substitute, maintain, unwind or dispose of any transaction(s) or asset(s) it deems
necessary to hedge the equity price risk of entering into and performing its obligations with
respect to the Transaction, or (B) realize, recover or remit the proceeds of any such
transaction(s) or asset(s) (a “Hedging Disruption”);

     (h) due to the adoption of, or any change in, any applicable law or regulation after the date
hereof, or due to the promulgation of, or any change in, the interpretation by any court, tribunal
or regulatory authority with competent jurisdiction of any applicable law or regulation after the
date hereof, (i) it becomes unlawful for Buyer or Seller to perform any absolute or contingent
obligation to make payment or delivery hereunder or to comply with any other material provision of
this Agreement or (ii) Buyer or Seller determines in good faith that (A) it has become illegal to
hold, acquire or dispose of Shares or (B) it would incur a materially increased cost in performing
its obligations hereunder (including, without limitation, due to any increase in tax liability,
decrease in tax benefit or other adverse effect on its tax position); or

     (i) Buyer declares or pays any dividend or distribution on the Shares in cash or other
property (other than additional Shares) other than dividends of the Dividend Amount (as set forth
in Schedule I) with record date of March 5, 2007 or May 29, 2007.

then, upon notice to Seller from Buyer or from Buyer to Seller, as the case may be, at any time
following such event, a “Termination Date” shall occur, and Buyer or Seller, as the case may be,
shall become obligated to make the payments or deliveries that would be made as if the final
Valuation Date in the Valuation Period were the Termination Date, the Final Settlement Amount were
the Termination Amount, and, if so elected by Buyer and if the Termination Amount is positive, Net
Share Settlement applied.

The “Termination Value” means the Final Settlement Amount determined as if the Termination
Date were the last Valuation Date, with a Daily Reference Share Amount equal to the Number of
Shares minus the sum of the Daily Reference Share Amounts for all previous Valuation Dates (such
difference, the “Termination Share Number”), and a Daily Reference Price equal to the average per
Share price obtained by the Calculation Agent from at least three experienced third party market
participants selected by the Calculation Agent as the price that each such participant would offer
to sell a block of Shares equal to the Termination Share Number.

The “Termination Amount” means a number of Shares with a value, as determined by the
Calculation Agent, as of the Termination Date equal the Termination Value.

Miscellaneous

     Section 9.01. U.S. Private Placement Representations. Each party hereby represents and
warrants to the other party as of the date hereof that:

     (a) It is an “accredited investor” (as defined in Regulation D under the Securities Act) and
has such knowledge and experience in financial and business matters as to be capable of evaluating
the merits and risks of the Transaction, and it is able to bear the economic risk of the
Transaction.

     (b) It is entering into the Transaction for its own account and not with a view to the
distribution or resale of the Transaction or its rights thereunder except pursuant to a

of, the Securities Act.

12

 

     Section 9.02. Bankruptcy of Buyer. Seller agrees that in the event of the bankruptcy of
Buyer, Seller shall not have rights or assert a claim that is senior in priority to the rights and
claims available to the shareholders of the common stock of Buyer.

     Section 9.03. 10b5-1. Buyer may at any time deliver a notice (a “Plan Commencement Notice”)
to Seller that Buyer desires that, from and after the date of such notice (the “Plan Commencement
Date”) until the earlier of the Settlement Date or the next Plan Termination Date (as defined
below), if any (such period, a “Plan Period”), the Transaction constitute a plan or agreement of
the type contemplated in Rule 10b5-1(c) (a “Plan”). During any Plan Period, the parties intend for
the Transaction to comply with the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act
and this Agreement to constitute a binding contract, instruction or plan satisfying the
requirements of 10b5-1(c) and to be interpreted to comply with the requirements of Rule 10b5-1(c).
Buyer may, by written notice, terminate or modify such 10b5-1 Plan in accordance with provisions of
Rule 10b5-1(c). During any Plan Period, Buyer may, subject to Section 7.01(f), deliver a notice (a
“Plan Termination Notice”; the date of such notice, a “Plan Termination Date”) to Seller that Buyer
no longer desires that the Transaction constitute a Plan.

     Section 9.04. Securities Contract. The parties hereto acknowledge and agree that Seller is a
financial institution within the meaning of Section 101(22) of Title 11 of the United States Code
(the “Bankruptcy Code”). The parties hereto further recognize that the Transaction is a
“securities contract”, as such term is defined in Section 741(7) of the Bankruptcy Code, entitled
to the protection of, among other provisions, Sections 555 and 362(b)(6) of the Bankruptcy Code,
and that each payment or delivery of cash, Shares or other property or assets hereunder is a
“settlement payment” within the meaning of Section 741(8) of the Bankruptcy Code.

     Section 9.05. No Collateral. The parties hereto acknowledge that the Transaction is not
secured by any collateral that would otherwise secure the obligations of Buyer hereunder.

     Section 9.06. Agreements to Deliver Documents. Seller and Buyer agree to deliver the
following documents, as applicable:

     Buyer will deliver to Seller, upon execution of this Agreement,

     (i) evidence reasonably satisfactory to the other party as to the names, true
signatures and authority of the officers or officials signing this Agreement on its behalf,

     (ii) certified resolutions evidencing necessary corporate authority and approvals with
respect to the execution, delivery and performance by Buyer of this Agreement,

     (iii) a certified copy of each of the current Certificate of Incorporation and By-laws
of Buyer, and

     (iv) an opinion of counsel to Buyer (which opinion may be from internal counsel to
Buyer) acceptable to Seller to the effect set forth in Annex C hereto.

     Section 9.07. Assignment. The rights and duties under this Agreement may not be assigned or
transferred by any party hereto without the prior written consent of the other parties hereto, such
consent not to be unreasonably withheld; provided that Seller may assign or transfer any of its
rights or duties hereunder to any of its affiliates without the prior written consent of Buyer.

     Section 9.08. Non-Confidentiality. The parties hereby agree that (i) effective from the date
of commencement of discussions concerning the Transaction, Buyer and each of its employees,
representatives, or other agents may disclose to any and all persons, without limitation of any
kind, the tax treatment and tax structure of the Transaction and all materials of any kind,
including opinions or other tax analyses, provided by Seller and its affiliates to Buyer relating
to

13

 

such tax treatment and tax structure, and (ii) Seller does not assert any claim of proprietary
ownership in respect of any description contained herein or therein relating to the use of any
entities, plans or arrangements to give rise to a particular United States federal income tax
treatment for Buyer.

     Section 9.09. Indemnification. Buyer agrees to indemnify and hold harmless Seller, its
affiliates, their respective directors, officers, employees, agents, advisors, brokers and
representatives and each person who controls Seller or its affiliates within the meaning of either
the Securities Act or the Exchange Act against, and Buyer agrees that no indemnified party shall
have any liability to Buyer or any of its affiliates, officers, directors, or employees for, any
losses, claims, damages, liabilities (whether direct or indirect, in contract, tort or otherwise)
or expenses, joint or several, to which any indemnified party may become subject under the
Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common
law or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions,
claims, investigations or proceedings in respect thereof, whether commenced or threatened) (i)
arise out of or relate to (A) actions or failures to act by Buyer or (B) actions or failures to act
by an indemnified party with the consent of or upon the direction of Buyer or (ii) otherwise arise
out of or relate to the Transaction or any related transactions, provided that this clause (ii)
shall not apply to the extent, but only to the extent, that any losses, claims, damages,
liabilities or expenses of an indemnified party have resulted primarily from the gross negligence
or willful misconduct of such indemnified party in which case Seller shall indemnify Buyer for any
losses, claims, damages, liabilities (whether direct or indirect, in contract, tort or otherwise)
or expenses which Buyer may suffer as a result of such indemnified party’s gross negligence or
willful misconduct. Buyer agrees to reimburse promptly each such indemnified party for any legal
or other expenses reasonably incurred by them in connection with investigating or defending any
such loss, claim, damages, liability, expense or action. This indemnity agreement will be in
addition to any liability which Buyer may otherwise have.

     Section 9.10. Legal Proceedings. Buyer shall not, without the prior written consent of
Seller, effect any settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been sought hereunder by
such indemnified party, unless such settlement includes an unconditional release of such
indemnified party from all liability arising from such proceeding.

     Section 9.11. Contribution. If the indemnification provided for above is unavailable to an
indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to
herein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party,
shall contribute to the amount paid or payable by such indemnified party as a result of such
losses, claims, damages, liabilities or expenses, in such proportion as is appropriate to reflect
not only the relative fault of Buyer on the one hand and of Seller on the other in connection with
the statements or omissions which resulted in such losses, claims, damages, expenses or
liabilities, but also any other relevant equitable considerations. The amount paid or payable by a
party as a result of the losses, claims, damages, liabilities and expenses referred to above shall
be deemed to include any legal or other fees or expenses reasonably incurred by such party in
connection with investigating or defending any action or claim. The parties agree that it would
not be just and equitable if contribution pursuant to this paragraph were determined by a method of
allocation that does not take account of the equitable considerations referred to in this
paragraph. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall
be entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.

the mutual waivers and certifications in this Section.

process in any other manner permitted by law.

     Section 9.14. Entire Agreement. This constitutes the entire agreement and understanding
among the parties with respect to the subject matter hereof and supersedes all oral communications
and prior writings with respect thereto.

if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by
Buyer and Seller or, in the case of a waiver, by the party against whom the waiver is to be
effective. No failure or delay by either party in exercising any right, power or privilege
hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof
preclude

15

 

any other or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any
rights or remedies provided by law.

     Section 9.16. No Third Party Rights, Successors and Assigns. This Agreement is not intended

respective successors and assigns and no other person shall assert any rights as third party
beneficiary hereunder. Whenever any of the parties hereto is referred to, such reference shall be
deemed to include the successors and assigns of such party. All the covenants and agreements
herein contained by or on behalf of Seller and Buyer shall bind, and inure to the benefit of, their
respective successors and assigns, subject to Section 9.07, whether so expressed or not, and shall
be enforceable by and inure to the benefit of Buyer and its successors and assigns, subject to
Section 9.07.

of this Section 9.17 have been met, shall be binding in the absence of manifest error. The
Calculation Agent will have no responsibility for good faith errors or omissions in any
determination or calculation under this Agreement. The parties acknowledge that the foregoing does
not preclude the parties from disputing that any determination or calculation of the Calculation
Agent was made in good faith or in a commercially reasonable manner. The Calculation Agent shall,
where reasonably practicable, make its determinations and calculations hereunder in consultation
with the parties hereto, and in all cases the Calculation Agent shall provide the parties hereto
with a schedule setting forth in reasonable detail the basis of each such determination or
calculation.

     Section 9.18. Limitation of Setoff. For purposes of the Transaction and for the
avoidance of doubt, Seller waives any right of set-off, recoupment or close-out netting that it may
be entitled to under any agreement relating to the Transaction or any applicable law.

APPENDIX A

to

ACCELERATED SHARE REPURCHASE AGREEMENT

Dated February 21, 2007

of the

TRANSACTION

between

CREDIT SUISSE, NEW YORK BRANCH

and

NORTHROP GRUMMAN CORPORATION

Conditions Precedent to Election of a Registered Offering

     This Appendix A supplements, forms a part of and is subject to the Agreement specified
above (the “Agreement”). Any capitalized term used but not defined herein shall have the meaning
set forth in the Agreement.

     Buyer may elect a Registered Offering as the Offering Method for the sale of Shares
delivered by Buyer (including any Additional Shares) to Seller in a Net Share Settlement only upon
satisfaction of the following conditions:

	(a)	 	Buyer shall have filed with the Commission pursuant to the Securities Act a registration
statement (the “Registration Statement”) or such other form as is acceptable to Seller,
covering all Shares to be sold by Seller; such registration statement shall have been declared
effective by the Commission with respect to such Shares on or prior to [          ] and no stop
order suspending the effectiveness of the Registration Statement shall be in effect, and no
proceedings for such purpose shall be pending before or threatened by the Commission.

	(b)	 	As of [          ], Buyer shall have delivered an underwriting agreement reasonably acceptable
to Seller, naming Seller or its designee, as underwriter, together with such other agreements,
certificates and instruments as Seller may reasonably require either pursuant to such
underwriting agreement or as are customarily provided together with such underwriting
agreement, and Buyer shall not be aware of material non-public information regarding the Buyer
or the Shares.

	(c)	 	Buyer shall have registered or qualified such Shares under such securities or “blue sky” laws
of such States and other jurisdictions in the United States of America and Puerto Rico as
Seller or any underwriter shall have reasonably requested, and shall have done any and all
other acts and things as may be reasonably necessary to be done by Buyer to enable Seller or
any underwriter to consummate the disposition in such jurisdictions of the Shares covered by
the Registration Statement; provided that Buyer shall not be required to make any filing or
take any action as a result of this paragraph (d) that would require Buyer to qualify as a
foreign corporation or file a general consent to service of process in any jurisdiction.

	(d)	 	Buyer shall have caused such Shares and the issuance thereof to be registered with or
approved by such other governmental agencies or authorities in the United States of America as
may be reasonably
necessary to be done by Buyer to enable Seller or any underwriter to consummate the
disposition of such Shares.

	(e)	 	Buyer shall have (i) given Seller and its underwriter(s), if any, and their respective
counsel and accountants, the opportunity to participate in the preparation of all materials
filed with the Commission pursuant to the Exchange Act or any other governmental

A-1 

 

	 	 	agency (the
“Filed Materials”) prior to [          ] [the first day on which any sale of Shares is effected
under the Registration Statement], (ii) furnished to each of them copies of all such Filed
Materials (and all documents incorporated therein by reference) sufficiently in advance of
filing to provide them with a reasonable opportunity to review such documents and comment
thereon, (iii) given each of them such access to its books and records and such opportunities
to discuss the business of Buyer with its officers and the independent public accountants who
have issued a report on its financial statement as shall be reasonably necessary, in the
opinion of Seller and such underwriter(s) or their respective counsel, to conduct a reasonable
investigation (within the meaning of the Securities Act) with respect to such Filed Materials,
(iv) delivered to Seller and its underwriter(s), if any, the financial statements of Buyer
filed with the Commission, (v) included in such Filed Materials material, furnished to Buyer
in writing, which in the reasonable judgment of Seller or its underwriter(s), if any, should
be included with respect to Seller, Seller’s underwriter(s) and the “Plan of Distribution”,
including, without limitation, language to the effect that the holding by Seller of the Shares
is not to be construed as a recommendation by Seller of the investment quality thereof and
(vi) if requested by Seller, deleted from such Filed Materials any reference to Seller by name
or otherwise if in the written opinion of counsel to Seller, such reference to Seller by name
or otherwise is not required by the Securities Act or any similar Federal statute or
applicable law then in force.

	(f)	 	Buyer shall have furnished to Seller and any underwriter, addressed to Seller and any such
underwriter before [          ], (i) an opinion of counsel for Buyer (which opinion may be
from internal counsel for Buyer) and (ii) a “cold comfort” letter signed by the independent
public accountants who have issued a report on Buyer’s financial statements included in such
Registration Statement, each in form and substance satisfactory to Seller and any such
underwriter and their respective counsel covering substantially the same matters with respect
to such Shares and the offering, sale and issuance thereof and the financial statements of
Buyer as are customarily covered in opinions of Buyer’s counsel and in accountants’ letters
delivered to underwriter(s) in underwritten public offerings of securities and, in the case of
