(ii) to confirm to and agree with the transferor and the other parties hereto as follows: (A) other
than as provided in any written instrument of transfer executed by the transferor and such
transferee, such transferor makes no representation or warranty and assumes no responsibility with
respect to any statements, warranties or representations made in or in connection with this
Agreement or any other Operative Document or the execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement or any other Operative Document or any other
instrument or document furnished pursuant hereto or thereto; (B) such transferor makes no
representation or warranty and assumes no responsibility with respect to the financial condition of
the Bank or the performance or observance by the Bank of any of its obligations under any Operative
Document or any other instrument or document furnished pursuant thereto; (C) such transferee
confirms that it has received a copy of this Agreement, together with copies of the financial
statements referred to in Section 5.11 and such other documents and information as it has
deemed appropriate to make its own credit analysis and decision to purchase the Securities; (D)
such transferee shall, independently and without reliance upon the transferor or any other Holder
of Securities and based on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in

11

 

taking or not taking action under this Agreement; (E) such transferee agrees that it shall
perform in accordance with their terms all of the obligations which by the terms of this Agreement
are required to be performed by it as a Holder of a Security, and (F) such transferee represents
and warrants that it is, as of the effective date of the transfer of Securities thereto, a
transferee permitted under the terms of the Securities as contemplated in Section 3.05
hereof.

     2.04 Loss or Destruction of Security. Upon receipt by the Bank of evidence reasonably
satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any
Security, and in the case of loss, theft or destruction, of indemnity reasonably satisfactory to
it, or in the case of mutilation, upon surrender and cancellation thereof, the Bank, at its own
expense, shall execute and deliver, in lieu thereof, a new Security, dated and bearing interest
from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated
Security or dated the date of such lost, stolen, destroyed or mutilated Security if no interest
shall have been paid thereon.

     2.05 Method of Payment on Securities. So long as a Purchaser or a Purchaser’s nominee
shall be the Holder of any Security, the Bank shall pay all sums becoming due on such Security for
principal and interest by the method and at the address specified for such purpose below
Purchaser’s name in Schedule 1, or by such other method or at such other address as
Purchaser shall have from time to time specified to the Bank in writing for such purpose, without
the presentation or surrender of such Security or the making of any notation thereon, except that
upon written request of the Bank made concurrently with or reasonably promptly after payment or
prepayment in full of any Security, Purchaser shall surrender such Security for cancellation,
reasonably promptly after any such request, to the Bank at its principal executive office. Prior to
any permitted sale, transfer or other disposition of any Security held by a Purchaser or a
Purchaser’s nominee, Purchaser shall, at Purchaser’s election, either endorse thereon the amount of
principal paid thereon and the last date to which interest has been paid thereon or surrender such
Security to the Bank in exchange for a new Security or Securities pursuant to Section 2.03.

     2.06 Prepayment of Securities.

          (a) At any time and from time to time after the fifth anniversary of the date of issuance of
the Securities but not prior thereto, the Bank may (subject to the prior approval of the applicable
Federal Banking Regulator), upon not less than seven Business Days’ notice to Purchasers, prepay,
without premium or penalty thereon, the unpaid principal amount of the Securities, in whole or in
part, together with accrued interest thereon to the date of such prepayment on the principal amount
prepaid; provided that each partial prepayment shall be in an aggregate principal amount of not
less than $250,000.

          (b) Each partial prepayment of the Securities shall be allocated (in integral multiples of
$1,000) to all Securities at the time outstanding in proportion, as nearly as practicable, to the
respective unpaid principal amounts thereof not theretofore called for prepayment, with adjustments
to the extent applicable to compensate for any prior prepayments not made exactly in such
proportion; provided, however, that if as a result of such allocation, any Security held by an
Holder would be reduced to an amount of less than $1,000,000, the Bank shall, at the request of
such Holder, redeem the balance of such Security.

12

 

          (c) In the case of each prepayment of Securities pursuant to this Section 2.08, the
principal amount of each Security to be so prepaid or repurchased shall mature and become due and
payable on the date fixed for such prepayment or repurchase, together with interest on such
principal amount to be so prepaid accrued to such date. From and after such date, unless the Bank
shall fail to pay such principal amount to be so prepaid when so due and payable, together with the
interest, as aforesaid, interest on such principal amount shall cease to accrue. Any Security paid
or prepaid in full shall be surrendered to the Bank and canceled and shall not be reissued, and no
Security shall be issued in lieu of any prepaid or repurchased principal amount of any Security.

          (d) Notwithstanding anything to the contrary in this Section 2.06, the Securities may
not be redeemed or prepaid at the option of the Bank prior to the Maturity pursuant to this
Section 2.06 without the prior written consent of the applicable Federal Banking Regulator
if the Bank is undercapitalized, significantly undercapitalized or critically undercapitalized as
described in 12 C.F.R. Section 565.4(b), fails to meet its regulatory capital requirements under 12
C.F.R. Part 567, or, if after giving effect to such repayment, the Bank would fail to meet any of
such standards or if such approval is otherwise required by the capital regulations of the
applicable Federal Banking Regulator. The Bank shall apply to the OTS for any such
required prior written consent.

     2.07 Acquisition by Bank of Securities. The Bank shall not purchase, redeem, prepay or
otherwise acquire, directly or indirectly, any of the outstanding Securities except in accordance
with the terms of this Agreement and the Securities. The Bank shall promptly cancel all Securities
acquired by it pursuant to any payment, prepayment or purchase of Securities pursuant to any
provision of this Agreement and no Securities may be issued in substitution or exchange for any
such Securities.

     2.08 Securities Subordinate to Senior Debt.

          (a) The Bank shall not pay the principal of, or premium, if any, or interest on, the
Securities and may not repurchase, redeem or otherwise retire any Securities if any principal,
premium or interest in respect of Senior Debt is not paid when due or within any applicable grace
period (including at maturity) or any other default on Senior Debt occurs and the maturity of such
Senior Debt is accelerated in accordance with its terms unless, in either case, the default has
been cured or waived and any such acceleration has been rescinded or the payment due in respect of
such Senior Debt has been paid in full in cash. Without limiting the generality of the foregoing,
during the continuance of any default with respect to any Senior Debt pursuant to which the
maturity thereof may be accelerated immediately without further notice (except such notice as may
be required to effect such acceleration) or the expiration of any applicable grace periods, the
Bank shall not make payments on the Securities for a period (a “Payment Blockage Period”)
commencing upon the receipt by the Bank of written notice of such default from the Representative
of any Senior Creditor with respect to such Senior Creditor’s Senior Debt specifying an election to
effect a Payment Blockage Period (a “Blockage Notice”) and ending on the date, determined in good
faith by the Bank, (i) of repayment in full in cash of such Senior Debt or (ii) that the default
giving rise to such Blockage Notice is no longer continuing. Notwithstanding the provisions
described in the immediately preceding sentence (but subject to the provisions contained in the
first sentence of this Section 2.08(a)), unless the holders of Senior

13

 

Debt or the Representative of such holders shall have accelerated the maturity of such Senior
Debt, the Bank shall, upon the expiration of any Payment Blockage Period, resume payments of
accrued unpaid interest on, and regularly scheduled payments of principal of, indebtedness of the
Bank evidenced by the Securities.

          (b) Without limiting the generality of the foregoing, the obligations evidenced by the
Securities are subordinated on liquidation, as to principal, interest, and premium (if any) to all
claims against the Bank that have the same priority as savings accounts or higher. The indebtedness
of the Bank evidenced by the Securities, including the principal and premium, if any, and interest
shall be subordinate and junior in right of payment to its obligations to its depositors, its
obligations under bankers’ acceptances and letters of credit, and its obligations to its other
creditors, including its obligations to the Federal Reserve Bank, FDIC, and any rights acquired by
the FDIC as a result of loans made by the FDIC to the bank or the purchase or guarantee of any of
its assets by the FDIC pursuant to the provisions of 12 USC §1823(c), (d) or (e), whether now
outstanding or hereafter incurred. In the event of any insolvency, receivership, conservatorship,
reorganization, readjustment of debt, marshaling of assets and liabilities or similar proceedings
or any liquidation or winding up of or relating to the Bank, whether voluntary or involuntary, all
such obligations shall be entitled to be paid in full before any payment shall be made on account
of the principal of, or premium, if any, or interest, on the Securities. In the event of any such
proceedings, after payment in full of all sums owing on such prior obligations, the holder of the
Securities, together with any obligations of the Bank ranking on a parity with the Securities,
shall be entitled to be paid from the remaining assets of the Bank the unpaid principal thereof and
any unpaid premium, if any, and interest before any payment or other distribution, whether in cash,
property, or otherwise, shall be made on account of any capital stock or any obligations of the
Bank ranking junior to the Securities.

          (c) Except as otherwise expressly set forth in this Section 2.08, nothing herein shall
impair the obligation of the Bank, which is absolute and unconditional, to pay the principal of and
interest on the Securities according to their terms.

          (d) Notwithstanding anything to the contrary, (1) the Bank shall not pay interest on the
Securities while it remains in default in the payment of any assessment due to the FDIC, and (2) in
accordance with and subject to 12 U.S.C. §1831o(h) (or its successor statute), if the Bank becomes
a critically undercapitalized insured depository institution under such statute, it shall not,
beginning 60 days after becoming critically undercapitalized, make any payment of principal or
interest on the Securities. The Bank shall promptly notify the Holders upon becoming aware of any
facts that would result in the Bank being prohibited from paying interest on the Securities in
accordance with the preceding sentence.

          (e) Each Holder by accepting a Security agrees that the Debt evidenced by such Security is
subordinated in right of payment, to the extent and in the manner provided in this Section
2.9, to the prior payment in full (including both interest and principal) of all Senior Debt
and that the subordination is for the benefit of and enforceable by the Holders of Senior Debt.

          (f) Nothing in this Section 2.08 shall prevent any Holder of Securities from
exercising its respective available remedies upon an Event of Default, subject to the rights of

14

 

holders of Senior Debt to receive distributions otherwise payable to Holders of the
Securities. Should any payment or prepayment on account of the Securities (whether principal,
interest or otherwise) be received by the Holders in contravention of this Section 2.08,
the Holders shall deliver the same to the Senior Creditors for application on the Senior Debt, and
the Holders agree that, until so delivered, the same shall be deemed received by the Holders as
agents for the Senior Creditors and such payment or prepayment shall be held in trust by the
Holders as property of the Senior Creditors.

          (g) If the FDIC shall be appointed as receiver for the Bank and in its capacity as such shall
have caused the Bank to merge with or into another financial institution, or in such capacity shall
sell or otherwise convey part or all of the assets of the Bank to another financial institution or
shall arrange for the assumption of less than all of the liabilities of the Bank by one or more
other financial institutions, the FDIC shall have no obligation, either in its capacity as receiver
or in its corporate capacity, to contract for or to otherwise arrange for the assumption of the
obligation represented by the Securities in whole or in part by any financial institution or
institutions which results from any such merger or which has purchased or otherwise acquired from
the FDIC as receiver for the Bank, any of the assets of the Bank, or which pursuant to any
arrangement with the FDIC, has assumed less than all of the liabilities of the Bank. To the extent
that the obligations represented by the Securities have not been assumed in full by a financial
institution with or into which the Bank may have been merged, as described in this paragraph (i),
and/or by one or more financial institutions which have succeeded to all or a portion of the assets
of the Bank, or which have assumed a portion but not all of the liabilities of the Bank as a result
of one or more transactions entered into by the FDIC as receiver of the Bank, then the holder of
the Securities shall be entitled to payments on the related obligation in accordance with any
procedures or priorities set forth in any applicable receivership regulations or in orders of the
FDIC relating to such receivership.

          (h) In the event that the obligation represented by the Securities is assumed in full by
another financial institution, which shall succeed by merger or otherwise to substantially all of
the assets and the business of the Bank, or which shall by arrangement with the FDIC assume all or
a portion of the liabilities of the Bank, and payment or provision for payment shall have been made
in respect of all matured installments of interest upon the Securities together with all
installments of principal on the Securities which shall have become due other than by acceleration,
then any default caused by the appointment of a receiver for the Bank shall be deemed to have been
cured, and any declaration consequent upon such default declaring the principal and interest on the
Securities to be immediately due and payable shall be deemed to have been rescinded.

          (i) The Securities are not secured by any assets of the Bank, or any affiliate (as defined in
12 C.F.R. Section 583.2) of the Bank. The Securities are not eligible as collateral for any loan
by the Bank.

          (j) Notwithstanding any other provisions hereof or of the Securities, including specifically
those set forth in the sections relating to subordination, events of default and covenants of the
Bank, it is expressly understood and agreed that if the applicable Federal Banking Regulator is the
OCC, then the OCC or any receiver or conservator of the Bank appointed by the OCC shall have the
right in the performance of his legal duties, and as part of

15

 

liquidation designed to protect or further the continued existence of the Bank or the rights of any
parties or agencies with an interest in, or claim against, the Bank or its assets, to transfer or
direct the transfer of the obligations evidenced by the Securities or otherwise evidenced hereby to
any bank or bank holding company selected by such official which shall expressly assume the
obligation of the due and punctual payment of the unpaid principal, and interest and premium, if
any, on the Securities or hereunder and the due and punctual performance of all covenants and
conditions hereunder or under the Securities; and the completion of such transfer and assumption
shall serve to supersede and void any default, acceleration or subordination which may have
occurred, or which my occur due or related to such transaction, plan, transfer or assumption,
pursuant to the provisions of the Securities or otherwise hereunder, and shall serve to return the
Holder to the same position, other than for substitution of the obligor, it would have occupied had
no default, acceleration or subordination occurred; except that any interest and principal
previously due, other than by reason of acceleration, and not paid shall, in the absence of a
contrary agreement by the Holders, be deemed to be immediately due and payable as of the date of
such transfer and assumption, together with the interest from its original due date at the rate
provided for herein or in the Securities.

without registration of any of the Units, the Convertible Preferred Stock, the Securities or the
Conversion Shares under the Securities Act, or any other applicable securities laws and regulations
(including the Securities Offering Regulations of the OTS and state securities laws) in reliance
upon exemptions from the registration requirements of the Securities Act and other applicable
securities laws. The Bank, the Parent and each Purchaser have entered into this Agreement to set
forth their understanding as to their relationship and their respective rights, duties and
obligations.

     3.05 Certificate Legends.

          (a) Upon original issuance thereof, the Securities certificates shall each contain such
legends as required pursuant to any of the Operative Documents, including without limitation, a
legend stating that the offer, sale or transfer of the Securities shall be made only (a) to the
Bank, (b) pursuant to Rule 144A under the Securities Act (“Rule 144A”), to a Person the transferor
reasonably believes is a “Qualified Institutional Buyer” as defined in Rule 144A (a “QIB”) that
purchases for its own account or for the account of a QIB to whom notice is given that the transfer
is being made in reliance on Rule 144A, provided that such QIB is also an “Accredited Investor”
within the meaning of subparagraph (a) (1), (2), (3) or (7) of Rule 501 under the Securities Act
(an “Accredited Investor”) or (c) an Accredited Investor that is acquiring the Security for its own
account, or for the account of an Accredited Investor, for investment purposes and not with a view
to, or for offer or sale in connection with, any distribution in violation of the Securities Act,
subject to the Bank’s right prior to any such offer, sale or transfer pursuant to clause (c) to
require the delivery of an opinion of counsel, certification or other information reasonably
satisfactory to it.

          (b) (i) Each Purchaser agrees that all certificates or other instruments representing the
Preferred Shares and the Conversion Shares subject to this Agreement shall bear a legend
substantially to the following effect:

(A) THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, OR SECURITIES LAWS OF ANY STATE AND MAY NOT BE
TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO A REGISTRATION
STATEMENT RELATING THERETO IN EFFECT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES
LAWS OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT OR SUCH LAWS.

(B) THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A VOTING AGREEMENT
AND TRANSFER AND OTHER RESTRICTIONS SET FORTH IN AN INVESTMENT AGREEMENT, DATED AS
OF JUNE 7, 2008, COPIES OF WHICH ARE ON FILE WITH THE ISSUER.

17

 

Upon request of the Purchaser, upon receipt by the Parent of an opinion of counsel reasonably
satisfactory to the Parent to the effect that such legend is no longer required under the
Securities Act and applicable state laws, the Parent shall promptly cause clause (A) of the
legend to be removed from any certificate for any Preferred Shares or Conversion Shares to be
transferred by the Purchaser in accordance with the terms of this Agreement and clause (B)
of the legend shall be removed upon the expiration of such transfer and other restrictions set
forth in this Agreement. The Purchaser acknowledges that neither the Preferred Shares nor the
Conversion Shares have been registered under the Securities Act or under any state securities laws
and the Purchaser agrees that it shall not sell or otherwise dispose of any of the Preferred Shares
or Conversion Shares, except in compliance with the registration requirements or exemption
provisions of the Securities Act and any other applicable securities laws.

          (c) The Units shall not be certificated or otherwise evidenced by any tangible form.

     3.06 No Offering Circular. The Securities are not being offered by an offering
circular filed with and declared effective by the OTS pursuant to 12 C.F.R. § 563g.2 but instead
are being sold in reliance upon an exemption from the offering circular requirement provided for by
12 C.F.R. §563g.3(b).

any individual capacity.

Section 5. REPRESENTATIONS AND WARRANTIES OF THE BANK AND THE PARENT.

The Bank represents and warrants to, and agrees with the Purchasers as of the date hereof and as of
the Closing Date as follows in Sections 5.01 through 5.29:

20

 

     5.01 Securities Laws Matters:

          (a) Neither the Bank, nor any of its “affiliates” (as defined in Rule 501(b) of Regulation D
under the Securities Act (“Regulation D”)), nor any Person acting on its or their behalf has
engaged in any form of general solicitation or general advertising (within the meaning of
Regulation D) in connection with any offer or sale of any of the Convertible Preferred Stock, the
Securities, the Units or the Conversion Shares.

          (b) Assuming the accuracy of the representations and warranties of the Purchaser and
compliance with the terms of this Agreement, it is not necessary in connection with the sale and
delivery of the Units or the Securities by the Bank in the manner contemplated by this Agreement to
register the Securities under the Securities Act, the Securities Offering Regulations of the OTS or
other applicable federal law.

          (c) The Units and the Securities (i) are not and have not been listed on a national securities
exchange registered under Section 6 of the Exchange Act, or quoted on a U.S. automated interdealer
quotation system, (ii) are exempt from the registration requirements of the Securities Act pursuant
to Section 3(a)(5) thereof, and (iii) are not of an open-end investment company, unit investment
trust or face-amount certificate company that are, or are required to be, registered under Section
8 of the Investment Company Act of 1940, as amended (the “Investment Company Act”), and the Units
and the Securities otherwise satisfy the eligibility requirements of Rule 144A(d)(3) promulgated
pursuant to the Securities Act.

          (d) The Securities are not offered by an offering circular filed with and declared effective
by the OTS pursuant to 12 C.F.R. § 563g.2 but instead are being sold in reliance upon an exemption

aggregate, adversely affect the consummation of the transactions contemplated by the Operative
Documents or have a Material Adverse Effect.

     5.15 Tax Returns. The Bank and each of its material Subsidiaries have timely and duly
filed all Tax Returns (defined below) required to be filed by them except where the failure to file
would not reasonably be expected to have a Material Adverse Effect, and all such Tax Returns are
true, correct and complete in all material respects. The Bank and each of its material
Subsidiaries have timely and duly paid in full all material Taxes required to be paid by them
(whether or not such amounts are shown as due on any Tax Return). There are no federal, state, or
other Tax audits or deficiency assessments proposed or pending with respect to the Bank or any of
its material Subsidiaries, and no such audits or assessments are threatened, except for those as to
which no Material Adverse Effect could reasonably be expected to result. As used herein, the terms

similar nature (whether imposed directly or through withholding), including any interest, additions
to tax, or penalties applicable thereto, imposed by any Governmental Entity,

25

transactions in, and dispositions of, the assets of, and the results of operations of, the Bank and

controls sufficient to provide reasonable assurances that (i) transactions are executed in
accordance with management’s general and/or specific authorizations, (ii) transactions are recorded
as necessary to permit preparation of financial statements in accordance with GAAP and to maintain
asset accountability, (iii) access to assets is permitted only in accordance with management’s

other risks customarily insured against. All policies of insurance and fidelity or surety bonds

Subsidiaries’ respective businesses, assets, employees, officers and directors are in full force
and effect. The Bank and each of the Significant Subsidiaries are in compliance with the terms of
such policies and instruments in all material respects. Neither the Bank nor any Significant
Subsidiary has reason to believe that it shall not be able to renew its existing insurance coverage
as and when such coverage expires or to obtain similar coverage from similar insurers as may be
necessary to continue its business at a cost that would not have a Material Adverse Effect. Within
the past 12 months, neither the Bank nor any Significant Subsidiary has been denied any insurance
coverage which it has sought or for which it has applied.

applicable federal and state occupational safety and health and environmental laws and regulations
to conduct their respective businesses, and the Bank and each of its Subsidiaries is in compliance
with all terms and conditions of any such permit, license or approval, except any such violation of
law or regulation, failure to receive required permits, licenses or other approvals or failure to
comply with the terms and conditions of such permits, licenses or approvals which would not, singly
or in the aggregate, result in a Material Adverse Effect.

     5.20 Conduct of Business. The Bank is conducting its business in compliance in all
respects with all laws, rules, regulations, decisions, directives and orders (including, without
limitation, all regulations and orders of, or agreements with the Federal Banking Regulator)

Material Adverse Effect.

     5.21 ERISA. The Bank and its Subsidiaries have fulfilled, in all material respects,
its obligations, if any, under the minimum funding standards of ERISA Section 302, and the
regulations promulgated thereunder with respect to each “plan” (as defined in Section 3(3) of ERISA

material respects with all applicable federal, state, and local environmental laws and regulations,
including, without limitation, those applicable to emissions to the environment, waste management,
and waste disposal (collectively, the “Environmental Law”), except where such noncompliance could
not be reasonably expected to have a Material Adverse Effect, and to the knowledge of the Bank,
there are no circumstances that would materially increase the cost of such compliance in the future
and result in a Material Adverse Effect. There is no claim under any Environmental Law, including
common law, pending or, to the knowledge of the Bank, threatened against the Bank or any of its
Subsidiaries (an “Environmental Claim”), which would be reasonably likely to have a Material
Adverse Effect, and, to the knowledge of the Bank, under applicable law, there are no past or
present actions, including without limitation, releases of any material into the environment, that
are reasonably expected to form the basis of any Environmental Claim against the Bank or any of its
Subsidiaries which would be reasonably expected to have a Material Adverse Effect.

title to all real properties and all other material properties and assets that purport to be owned
by them, in each case free from liens, encumbrances, claims and defects that would affect the value
thereof or interfere with the use made or to be made thereof by them, but subject to liens on the

27

 

assets of the Bank and RWHC in favor of the Federal Home Loan Bank of Dallas, which do not
materially affect the value of such properties in the aggregate to the Bank and its Subsidiaries
considered as one enterprise. The Bank and its Subsidiaries hold all leased real or personal
property under valid and enforceable leases with no exceptions that would interfere with the use
made or to be made thereof by them, except for such claims that would not singly or in the
aggregate have a Material Adverse Effect and neither the Bank nor any Subsidiary of the Bank has
any notice of any claim of any sort that has been asserted by anyone adverse to the rights of the
Bank or any Subsidiary of the Bank under any such leases or subleases, or affecting or questioning
the rights of such entity to the continued possession of the leased or subleased premises under any
such lease or sublease, except for such claims that would not, singly or in the aggregate, have a
Material Adverse Effect.

     5.24 Intellectual Property. Each of the Bank or its Subsidiaries, as applicable, (i)
owns or possesses, or can acquire on reasonable terms, adequate patents, patent rights, licenses,
inventions, copyrights, know-how (including trade secrets and other unpatented and/or unpatentable
proprietary or confidential information, systems or procedures), trademarks, service marks, trade
names or other intellectual property (collectively, “Intellectual Property”) presently employed by
them in connection with the business now operated by them or reasonably necessary in order to
conduct such business, except for such Intellectual Property the lack of which would not reasonably
be expected to have a Material Adverse Effect, and (ii) neither the Bank nor any of its
Subsidiaries has received any notice or is otherwise aware of any infringement of or conflict with
asserted rights of others with respect to any Intellectual Property or any facts or circumstances
which would render any Intellectual Property invalid or inadequate to protect the interest of the
Bank or any of its Subsidiaries therein, except for such infringement, conflict, invalidity or
inadequacy as would not reasonably be expected to have a Material Adverse Effect.

     5.25 Loans. Each loan reflected as an asset in the Bank Financial Statements or
Interim Financial Statements (i) is evidenced by notes, agreements or other evidences of
indebtedness that are true, genuine and what they purport to be, except for such matters as would
not reasonably be expected to have a Material Adverse Effect, (ii) to the extent secured, has been
secured by valid liens and security interests that have been perfected, except for such for such
failures to perfect as would not reasonably be expected to have a Material Adverse Effect and (iii)
is the legal, valid and binding obligation of the obligor named therein, enforceable in accordance
with its terms, subject to bankruptcy, insolvency, fraudulent conveyance and other laws of general
applicability relating to or affecting creditors’ rights and to general equity principles and
except for such unenforceable matters as would not reasonably be expected to have a Material
Adverse Effect.

     5.26 Allowance for Loan Losses. The allowance for loan losses reflected on the Bank
Financial Statements or Interim Financial Statements, as of their respective dates, is adequate in
all material respects under the requirements of GAAP.

     5.27 Repurchase Agreements. With respect to all agreements pursuant to which the Bank
or any of its Subsidiaries has purchased securities subject to an agreement to resell, if any, the
Bank or such Subsidiary, as the case may be, has a valid, perfected first lien or security interest
in or evidence of ownership in book entry form of the government securities or other

28

 

collateral securing the repurchase agreement, and the value of such collateral equals or
exceeds the amount of the debt secured thereby, except where the failure to so perfect, or the
inadequacy of value, would not reasonably be expected to have a Material Adverse Effect.

     5.28 Bank Secrecy Act, Anti-Money Laundering and OFAC and Customer Information. The
Bank is not aware of, has not been advised of, and has no reason to believe that any facts or
circumstances exist, which would cause it or any of its Subsidiaries to be deemed (i) to be
operating in violation in any material respect of the Bank Secrecy Act, the Uniting and
Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism
Act of 2001 (also known as the USA PATRIOT Act), any order issued with respect to anti-money
laundering by the U.S. Department of the Treasury’s Office of Foreign Assets Control, or any other
applicable anti-money laundering statute, rule or regulation; or (ii) not to be in satisfactory
compliance in any material respect with the applicable privacy and customer information
requirements contained in any federal and state privacy laws and regulations, including, without
limitation, in Title V of the Gramm-Leach-Bliley Act of 1999 and the regulations promulgated
thereunder, as well as the provisions of the information security program adopted by Bank pursuant
to 12 C.F.R. Part 570, except where the failure to so comply would not reasonably be expected to
have a Material Adverse Effect. It is not aware of any facts or circumstances that would cause it
to believe that any non-public customer information has been disclosed to or accessed by an
unauthorized third party in a manner that would cause it or any of its Subsidiaries to undertake
any material remedial action, except where the failure to comply would not reasonably be expected
to have a Material Adverse Effect. The Bank’s Board of Directors (or, where appropriate, the board
of directors of any of Bank’s Subsidiaries) has adopted and implemented an anti-money laundering
program that contains adequate and appropriate customer identification verification procedures that
comply with Section 326 of the USA PATRIOT Act and such anti-money laundering program meets the
requirements in all material respects of Section 352 of the USA PATRIOT Act and the regulations
thereunder, and it (or such other of its Subsidiaries) has complied in all respects with any
requirements to file reports and other necessary documents as required by the USA PATRIOT Act and
the regulations thereunder, except where the failure to so comply would not reasonably be expected
to have a Material Adverse Effect.

     5.29 Compliance with Laws. Each of the Bank and its Subsidiaries is in material
compliance with all applicable federal, state, local and foreign statutes, laws, regulations,
ordinances, rules, judgments, orders or decrees applicable thereto or to the employees conducting
such businesses, including, without limitation, the Equal Credit Opportunity Act, the Fair Housing
Act, the Community Reinvestment Act (“CRA”) (which includes a CRA Rating of “satisfactory” or
better), the Home Mortgage Disclosure Act and all other applicable fair lending laws and other laws
relating to discriminatory business practices, except where the failure to so comply would not
reasonably be expected to have a Material Adverse Effect.

thereof or interfere with the use made or to be made thereof by them but subject to liens on the
assets of the Bank and RWHC, in favor of the Federal Home Loan Bank of Dallas, which do not
materially affect the value of such properties in the aggregate to the Bank and its Subsidiaries
considered as one enterprise. The Parent and its Subsidiaries hold all leased real or personal

made or to be made thereof by them.

appropriate proceedings and for which reserves adequate in accordance with GAAP have been provided;

them to own or lease their properties and assets and to carry on their business as presently
conducted and that are material to the business of the Parent or such Subsidiary. The Parent and

transactions, arrangements or other relationships with the Parent that may create contingencies or

this Agreement, upon the receipt of the Stockholder Approval, or the expiration of any period
beyond which agreements to vote are not enforceable under applicable law, whichever comes first.

Securities to the contrary notwithstanding; provided however, that (i) the foregoing remedy shall
not apply, and the Holders right to accelerate as aforesaid shall be postponed, in the event that
the provisions of Section 2.10 require that the payment of any indebtedness or any other
obligations to the Holders must be subordinated and postponed until satisfaction in full of Senior
Debt or other obligations described in Section 2.10, and (ii) the principal amount and
accrued interest on the Securities shall not become due and payable pursuant to this Section
8(a) without the prior written consent of the OTS if the Bank is undercapitalized,
significantly undercapitalized or critically undercapitalized as described in 12 C.F.R. §565.4(b),
fails to meet its regulatory capital requirements under 12 C.F.R. Part 567, or, if after giving
effect to such payment, the Bank would fail to meet any of such standards or to the extent
otherwise prohibited by the capital regulations of the OTS. The Bank shall apply to the OTS
for any such required prior written consent upon receipt from the registered holder of the
Securities of the notice referred to in the preceding sentence.

          (b) The Holders of a majority in aggregate principal amount of the Securities by written
notice to the Bank may rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree of a court of competent jurisdiction already rendered and if
all existing Events of Default with respect to Securities have been cured or

40

 

waived except nonpayment of principal, premium, if any, or interest that has become due solely
because of acceleration. Upon any such rescission, the parties hereto shall be restored
respectively to their several positions and rights hereunder, and all rights, remedies and powers
of the parties hereto shall continue as though no such proceeding had been taken.

          (c) If an Event of Default occurs and is continuing, subject to Section 2.10 (which
shall control over and limit the exercise of any rights or remedies by the Holders under this
Section 8), each of the Holders may pursue any available remedy to collect the payment of
principal of or interest on, the Securities or to enforce the performance of any provision of the
Securities or this Agreement. A delay or omission by any of the Holders in exercising any right or
remedy occurring upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence on the Event of Default. All remedies are cumulative to the extent
permitted by law.

Section 9. PAYMENT OF EXPENSES.

     9.01 Expenses. Each of the Parent and the Bank hereby covenants and agrees that it
shall pay or cause to be paid (directly or by reimbursement) all costs and expenses incident to the
performance of the obligations of the Bank under this Agreement, whether or not the transactions
contemplated herein are consummated or this Agreement is terminated, including (i) all costs and
expenses incident to the authorization, issuance, sale and delivery of the Securities and any taxes
payable in connection therewith; (ii) the fees and expenses of qualifying the Securities under the
securities laws of the several jurisdictions as provided in Section 3.04; and (iii) the
fees and expenses of the counsel, the accountants and any other experts or advisors retained by the
Bank.

     9.02 Termination Expenses. If the sale of the Units provided for in this Agreement is
not consummated because any condition set forth in Section 4 to be satisfied by the Bank or
the Parent is not satisfied, because this Agreement is terminated pursuant to Section 10 or
because of any failure, refusal or inability on the part of the Bank or the Parent to perform all
obligations and satisfy all conditions on its part to be performed or satisfied hereunder other
than by a reason of a default by any of the Purchasers, the Bank shall reimburse the Purchasers
upon demand for all reasonable out-of-pocket expenses up to an aggregate amount of $100,000 that
shall have been incurred by the Purchasers in connection with the proposed purchase and sale of the
Securities, including the fees and expenses of counsel for the Purchasers. [If the reasonable
out-of-pocket expenses of all Purchasers exceeds $100,000, such amount shall be divided among the
Purchasers pro rata in accordance with the number of Securities to be purchased by each Purchaser
as set forth on Schedule 1, but the Bank shall have no liability or obligation with respect
to such excess. The Bank shall not in any event be liable to the Purchasers for the loss of
anticipated profits from the transactions contemplated by this Agreement.

Section 10. TERMINATION.

     This Agreement shall be subject to termination in the absolute discretion of any Purchaser
with respect to itself, by notice given to the Bank prior to delivery of and payment for the Units,
if prior to such time (i) the Bank and the Parent shall be unable to sell and deliver the Units to
the Purchasers, including at least $275,000,000 principal amount of Securities on the Closing Date,
(ii) any circumstance or event has occurred that has resulted in a Material Adverse

41

 

Effect, or (iii) if for any reason, the conditions set forth in Section 4 have not been
satisfied within six (6) months after the execution of this Agreement (which date may be extended
at the option of all of the Purchasers for an additional two (2) months).

Section 11. MISCELLANEOUS.

     11.01 Disclosure Schedule. The term “Disclosure Schedule,” as used herein, means the
schedule, if any, attached to this Agreement that sets forth items the disclosure of which is
necessary or appropriate as an exception to one or more representations or warranties contained in
Section 5 hereof. The Disclosure Schedule shall be arranged in paragraphs corresponding to
the section numbers contained in Section 5. Nothing in the Disclosure Schedule shall be
deemed adequate to disclose an exception to a representation or warranty made herein unless the
Disclosure Schedule identifies the exception with reasonable particularity and describes the
relevant facts in reasonable detail. Without limiting the generality of the immediately preceding
sentence, the mere listing (or inclusion of a copy) of a document or other item in the Disclosure
Schedule shall not be deemed adequate to disclose an exception to a representation or warranty made
herein unless the representation or warranty has to do with the existence of the document or other
item itself. Information provided by the Bank in response to any due diligence questionnaire shall
not be deemed part of the Disclosure Schedule and shall not be deemed to be an exception to one or
more representations or warranties contained in Section 5 hereof unless such information is
specifically included on the Disclosure Schedule in accordance with the provisions of this
Article 5.

     11.02 Cooperation. The Parent, the Bank and the Purchasers shall use commercially
reasonable best efforts to obtain, as promptly as practicable, all governmental,
quasi-governmental, court or regulatory approvals, consents or statements of non-objection
necessary to complete the transactions contemplated by this Agreement. The Parent, the Bank and
the Purchasers shall cooperate with the each other and use commercially reasonable efforts to take,
or cause to be taken, all commercially reasonable actions in order to facilitate the successful
consummation of the transactions contemplated hereby. Without limiting the generality of the
foregoing, in order to assure that the OTS approves the inclusion of the face amount of the
Securities as Tier-2 Capital as set forth in Section 3.02, the Parent, the Bank and the
Purchasers shall cooperate in and effect such reasonable amendments to the Operative Documents as
and to extent required by the OTS in order to obtain such approval as Tier-2 Capital.

     11.03 Notices. All communications hereunder shall be in writing and effective only on

or otherwise, without the Purchasers’ prior written consent. The rights and obligations of a
Purchaser under this Agreement may be assigned without the Bank’s or the Parent’s consent; provided
that the assignee assumes the obligations and makes the representations of the Purchaser under this
Agreement.

PARTY HERETO OR WITH RESPECT TO OR ARISING OUT OF THIS AGREEMENT MAY BE BROUGHT IN OR REMOVED TO
THE COURTS OF THE STATE OF NEW YORK, IN AND FOR NEW YORK COUNTY, OR OF THE UNITED STATES OF AMERICA

     11.10 Entire Agreement. This Agreement, together with the Operative Documents, the
Certificate of Designations and the other documents delivered in connection with the transactions
contemplated by this Agreement, is intended by the parties as a final expression of their agreement
and intended to be a complete and exclusive statement of the agreement and understanding of the
parties hereto in respect of the subject matter contained herein and therein. There are no
restrictions, promises, warranties or undertakings, other than those set forth or referred to
herein and therein. This Agreement, together with the Operative Documents, the Certificate of
Designations and the other documents delivered in connection with the transaction contemplated by

unenforceable in any respect for any reason, the validity, legality and enforceability of any such
provision in every other respect and of the remaining provisions hereof shall not be in any way
impaired or affected, it being intended that all of the Purchasers’ rights and privileges shall be
enforceable to the fullest extent permitted by law.

          (b) The obligations of the Purchasers contained herein are several, and not joint or joint and

delivered hereunder shall terminate on and as of the Closing.

     11.13 Savings Clause. It is the intent of Purchaser and Bank in the execution and
performance of this Agreement and the Securities to remain in strict compliance with applicable law
from time to time in effect. In furtherance thereof, Purchaser and Bank stipulate and agree that
none of the terms and provisions contained in this Agreement or the Securities shall ever be
construed to create a contract to pay for the use, forbearance or detention of money with interest

44

 

at a rate or in an amount in excess of the highest lawful rate or amount of interest permitted
to be charged under applicable law. For purposes of this Agreement and the Securities “interest”
shall include the aggregate of all charges which constitute interest under applicable law that are
contracted for, charged, reserved, received or paid under this Agreement or any promissory note
executed in connection herewith. Bank shall never be required to pay unearned interest and shall
never be required to pay interest, at a rate or in an amount in excess of the highest lawful rate
permitted by applicable law (the “Highest Lawful Rate”) or an amount of interest that may be
lawfully charged under applicable law, and the provisions of this paragraph shall control over all
other provisions of this Agreement or any promissory note executed in connection herewith, and of
any other instrument pertaining to or securing the obligations arising under this Agreement or any
promissory note executed in connection herewith, which may be in actual or apparent conflict
herewith. If any such note is prepaid, or if the maturity of any such note is accelerated for any
reason, or if under any other contingency the effective rate or amount of interest which would
otherwise be payable under this Agreement or any such note would exceed the Highest Lawful Rate or
amount of interest Purchaser or any other holder of Securities is allowed by Applicable Law to
charge, contract for, take, reserve or receive, or in the event Purchaser or any Holder shall
charge, contract for, take, reserve or receive monies that are deemed to constitute interest which
would, in the absence of this provision, increase the effective rate or amount of interest payable
under this Agreement or any promissory note executed in connection herewith to a rate or amount in
excess of that permitted to be charged, contracted for, taken, reserved or received under
applicable law then in effect, then the principal amount of such notes or owed hereunder or the
amount of interest which would otherwise be payable under such notes or hereunder or both shall be
reduced to the amount allowed under applicable law as now or hereinafter construed by the courts
having jurisdiction, and all such moneys so charged, contracted for, taken, reserved or received
that are deemed to constitute interest in excess of the Highest Lawful Rate permitted by applicable
law shall immediately be returned to or credited to the account of Bank upon such determination.
Purchaser and Bank further stipulate and agree that, without limitation of the foregoing, all
calculations of the rate or amount of interest contracted for, charged, taken, reserved or received
under this Agreement or any such note which are made for the purpose of determining whether such
rate or amount exceeds the Highest Lawful Rate or amount, shall be made to the extent not
prohibited by applicable law, by amortizing, prorating, allocating and spreading during the period
of the full stated term of the obligations owed hereunder or under such notes, all interest at any
time contracted for, charged, taken, reserved or received from Bank or otherwise by Purchaser or
any other holder of Securities.

June 7, 2008

Mr. Keith Meister

Managing Director

Icahn Partners LP

767 Fifth Avenue, 47th Floor

New York, New York 10153

Ladies and Gentlemen:

     Contemporaneously with the execution and delivery of this letter agreement (this “Agreement”),
Guaranty Financial Group Inc. (the “Company” or “we”) and Icahn Partners LP (the “Investor”) have
entered into that certain Investment Agreement of even date herewith (the “Investment Agreement”).
Capitalized terms used in this Agreement that are not otherwise defined herein shall have the
meaning given to them in the Investment Agreement. The Company and the Investor are entering into
this Agreement to agree to additional terms and conditions related to the transactions contemplated
by the Investment Agreement, as set forth below:

     1. Governance Matters.

     (a) Promptly following the Closing, the Investor and the Governance Committee of the
Board of Directors (the “Governance Committee”) will cooperate and work jointly to identify a
qualified individual who is “independent” for the purposes of the New York Stock Exchange
Rules and Rule 10A-3 promulgated under the Exchange Act that is acceptable to both the
Investor and the Governance Committee, and who satisfies all legal and governance
requirements regarding service as a director of the Company (the “Board Representative”), to
serve as a director of the Company. Following the identification of such Board
Representative as described above (the “Identification Process”), the Company will promptly,
and in no event later than thirty days following such identification, cause such Board
Representative to be appointed or elected to the Board of Directors. After such appointment
or election, so long as the Investor and its affiliates beneficially own (as determined in
accordance with Rule 13d-3 under the Exchange Act) an aggregate of at least 10% of the
outstanding shares of Common Stock (including for this purpose shares of Common Stock
issuable upon conversion of the Convertible Preferred Stock), the Company will be required to
recommend to its stockholders the election to the Board of Directors of the Board
Representative at the Company’s annual meeting, subject to satisfaction of all legal and
governance requirements regarding service as a director of the Company. If the Investor and
its affiliates no longer beneficially own (as determined in accordance with Rule 13d-3 under
the Exchange Act) in the aggregate the minimum number of Securities specified in the prior
sentence, the Investor will have no further rights and the Company will have no further
obligations under this Section 1.

 

 

     (b) The Board Representative (including any successor nominee) duly selected in
accordance with Section 1(a) shall, subject to applicable law, be one of the
Company’s and the Company’s Governance Committee’s nominees to serve on the Board of
Directors. The Company shall use all reasonable best efforts to have the Board
Representative elected as a director of the Company and the Company shall solicit proxies for
each such person to the same extent as it does for any of its other nominees to the Board of
Directors.

     (c) Upon the death, resignation, retirement, disqualification or removal from office of
the Board Representative, the Investor and the Governance Committee shall again engage in the
Identification Process to identify a replacement Board Representative. Following the
successful conclusion of the Identification Process, the Board of Directors will use its
reasonable best efforts to take all action required to fill the vacancy resulting from such
death, resignation, retirement, disqualification or removal, with such newly identified Board
Representative (including such person, subject to applicable law, being one of the Company’s
and the Company’s Governance Committee’s nominees to serve on the Board of Directors, using
all reasonable best efforts to have such person elected as director of the Company and the
Company soliciting proxies for such person to the same extent as it does for any of its other
nominees to the Board of Directors).

     (d) The Board Representative shall be entitled to the same compensation and same
indemnification in connection with his or her role as a director as the other members of the
Board of Directors, and each Board Representative shall be entitled to reimbursement for
documented, reasonable out-of-pocket expenses incurred in attending meetings of the Board of
Directors or any committees thereof, to the same extent as the other members of the Board of
Directors. The Company shall notify the Board Representative of all regular and special
meetings of the Board of Directors and shall notify the Board Representative of all regular
and special meetings of any committee of the Board of Directors of which the Board
Representative is a member.  The Company shall provide the Board Representative with copies
of all notices, minutes, consents and other materials provided to all other members of the
Board of Directors concurrently as such materials are provided to the other members.

     (e) For so long as the Board Representative is entitled to serve on the Board of
Directors, upon the Investor’s request, the Company will promptly take such actions as may be
necessary to appoint the Board Representative to the board of directors of Guaranty Bank and
the governing board of any bank or savings institution subsequently acquired by the Company.

     2. Expenses. Except as set forth in the Investment Agreement and that certain
Purchase Agreement between Guaranty Bank and the Investor dated as of even date herewith (the “Note
Purchase Agreement”), each of the Company and the Investor shall pay its respective fees and
expenses related to the transactions contemplated by this Agreement, the Investment Agreement and
the Note Purchase Agreement; provided, however, that the Company shall pay the Investor a one-time
fee of $350,000, which the

 

 

parties agree is a reasonable amount to reimburse the Investor for its expenses incurred in
connection with the transactions contemplated by this Agreement.

     3. Equivalent Treatment

     (a) The Company has advised the Investor that the Company has entered into that certain
Investment Agreement dated May 26, 2008 (as the same has been amended by that certain First
Amendment to Investment Agreement dated May 29, 2008, the “TRT Investment Agreement”) with
TRT Holdings, LLC (“TRT”), pursuant to which TRT has purchased Common Stock and will
purchase shares of the Company’s preferred stock. The Company hereby represents and warrants
to the Investor that (i) except as previously disclosed in the Company’s public filings with
the Securities and Exchange Commission, there are no agreements, side letters or
understandings in existence or contemplated between the Company and TRT or its affiliates
regarding an investment in the Company, the purchase or sale of debt or equity securities
issued by the Company or otherwise regarding the matters that are the subject of the TRT
Investment Agreement, or amending or supplementing the TRT Investment Agreement, and (ii)
the preferred stock to be issued to TRT or its affiliates pursuant to the TRT Investment
Agreement will be of the same series to be purchased by the Investor under the Investment
Agreement.

     (b) The Company has advised the Investor that the Company intends to agree to issue
additional subordinated notes and preferred stock on or about the date hereof to one or more
third parties (collectively, the “Other Investors”). The Company hereby represents and
warrants to the Investor that, other than the TRT Investment Agreement and any ancillary
documents, certificates and instruments delivered pursuant to the terms thereof (not
including any documents that substantively supplement, alter or amend the terms of the TRT
Investment Agreement), except as consented to by the Investor (i) in connection with such
purchases, each Other Investor will execute agreements in the same form as the Investment
Agreement and the Note Purchase Agreement to be executed by the Investor and (ii) there are
no agreements, side letters or understandings in existence or contemplated between the
Company and such Other Investor other than the form of Investment Agreement or Note Purchase
Agreement to be executed by each Other Investor.

     (c) From the date hereof through the date that is 180 days from the date hereof, the
Company shall not enter into any agreement, arrangement or understanding with any Person
relating to or contemplating the issuance of debt or equity securities of the Company or any
of its subsidiaries containing any material term or condition that is any more favorable to
any potential purchaser of such securities than the terms and conditions of the Investment
Agreement, this Agreement and the Note Purchase Agreement.

     4. No Representation or Warranty Regarding Certain Tax Matters. Notwithstanding any
provision to the contrary contained in the Investment Agreement, the Note Purchase Agreement or any
other agreement, the Company makes no

 

 

representation or warranty with respect to Section 4.03(d) of the Tax Matters Agreement
between it and Temple Inland dated December 11, 2007, including, without limitation, under
Section 3(d) and 3(h) of the Investment Agreement.

     5. Pre-Emptive Right. From the Closing Date until the earlier to occur of (a) the
first anniversary of the Closing Date and (b) the first date on which the Investor and its
affiliates cease to beneficially own in the aggregate 5% of the issued and outstanding Common
Stock, the Company and its subsidiaries shall not issue or sell any Subject Securities without
first complying with this Section 5. The Company hereby grants to the Investor the
preemptive right to purchase, pro rata, all or any part of the Subject Securities that the Company
or any of its subsidiaries may, from time to time, propose to sell or issue. In the event that
Subject Securities are offered or sold as part of a unit with other securities, the Investor must,
if the Investor elects to exercise its preemptive right to purchase the Subject Securities,
exercise its preemptive right with respect to all of the securities comprising part of the units on
the same terms that the Company proposes to offer such units to other parties (provided, however,
that Investor will not be obligated to pay part of any brokerage fees payable by such other party
pursuant to an agreement between such party and a broker). The Investor’s pro rata share for
purposes of this Section 5 is the ratio that the number of shares of Common Stock
beneficially owned by the Investor and its affiliates immediately before giving effect to the
proposed issuance of the Subject Securities bears to the total number of shares of Common Stock
then issued and outstanding. In the event the Company proposes to issue or sell Subject
Securities, it shall give the Investor written notice of its intention, describing the type of
Subject Securities and the price and terms upon which the Company proposes to issue or sell the
Subject Securities. The Investor shall have five Business Days from the date of such notice to
irrevocably agree to purchase up to its pro rata share of the Subject Securities for the price and
upon the terms (including brokerage, transaction, acquisition, advisory, due diligence, origination
or similar fees, but excluding expense reimbursements and underwriting discounts, fees or
commissions) specified in the notice by giving written notice to the Company stating the quantity
of Subject Securities agreed to be purchased. The Investor acknowledges that the acquisition of
the Subject Securities may be subject to stockholder approval under the rules of the New York Stock
Exchange and subject to any required approval from any Governmental Entity. In the event the
Investor fails to exercise such preemptive right within such five Business Day period, the Company
shall have 90 days to sell the Subject Securities not agreed to be purchased by the Investor at the
same price and upon the same terms specified in the Company’s notice described above. In the event
the Company has not sold the Subject Securities within such ninety-day period, the Company shall
not thereafter issue or sell any Subject Securities without first offering such securities in the
manner provided above. In the event that the Investor is entitled to the rights provided in this
Section 5 as the result of a registered offering of Subject Securities, the Investor shall be
entitled to exercise such rights through participation in such registered offering and the Company
shall ensure that enough units of Subject Securities shall be registered to permit such exercise.
For the purposes of this Section 5, the term “Subject Securities” means any debt or equity
securities of the Company (including common stock or preferred stock of the Company), or any debt
or equity security of the Company convertible or exchangeable for or into any debt or equity
security of the Company, but excludes (i) shares of Common Stock that are issued or are

 

 

issuable pursuant to a stock option plan, restricted stock plan, agreements or other incentive
stock arrangements approved by the stockholders and a majority of the Board of Directors or an
authorized committee thereof; (ii) shares of Common Stock issued in a split or subdivision of the
outstanding shares of Common Stock, a dividend or other distribution payable in additional shares
of Common Stock or other securities or rights convertible into, exchangeable for, or entitling the
holder thereof to receive directly or indirectly, additional shares of Common Stock (the “Common
Stock Equivalents”) without payment of any consideration by such holder for the additional shares
of Common Stock or the Common Stock Equivalents (including the additional shares of Common Stock
issuable upon conversion or exercise thereof), so long as the Investor is entitled to participate
in the same to the extent of any securities affected thereby that it holds on the applicable record
date for the same, (iii) shares of Common Stock issued pursuant to the Rights Offering or any
similar offerings in the future, so long as the Investor is permitted to participate in the same to
the extent of any common stock it holds as of the record date for the same, and (iv) securities
issued to TRT pursuant to the TRT Investment Agreement.

     6. Disclosure of Material Non-Public Information. The next Business Day following the
execution and delivery of this Agreement, the Company agrees to file a Current Report on Form 8-K
regarding the transactions contemplated by the Investment Agreement and the Note Purchase
Agreement. The Company hereby represents and warrants to the Investor that, upon the filing of
such Form 8-K, the Company will have disclosed in the Company SEC Documents all theretofor material
nonpublic information that the Company had previously provided to the Investor.

     7. Other Terms.

     (a) Severability. If any term, provision, covenant, or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, void, or
unenforceable, the remainder of the terms, provisions, covenants, and restrictions of this
Agreement will remain in full force and effect and will in no way be affected, impaired, or
invalidated.

     (b) Entire Agreement. This Agreement, together with the Investment Agreement
and the Note Purchase Agreement, contain the entire agreement between the parties concerning
the subject matter hereof and thereof and supersede all prior written, and prior or
contemporaneous oral, agreements, representations, arrangements, understandings, and
negotiations between the parties with respect to such matters.

     (c) Waivers and Amendment. This Agreement may be modified or the terms of this
Agreement waived only by a separate writing signed by the parties expressly so modifying or
waiving this Agreement or such terms. It is further understood and agreed that no failure or
delay by either party in exercising any right, power, or privilege under this Agreement will
operate as a waiver thereof, nor will any single or partial exercise thereof preclude any
other or further exercise thereof or the exercise of any right, power, or privilege under
this

 

 

     Agreement.

     (d) Assignment. No party to this Agreement may assign this Agreement, nor may
any party delegate any duties under this Agreement, without the prior written consent of the
other party, which consent may be withheld in such other party’s sole option and election.
Any assignment or delegation or attempted assignment or delegation of this Agreement without
the prior written consent of the other party will be void.

     (e) GOVERNING LAW. THIS AGREEMENT WILL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO THE CONFLICT OF
LAWS PRINCIPLES OF THAT STATE OR ANY OTHER PRINCIPLE THAT COULD REQUIRE THE APPLICATION OF
THE LAWS OF ANY OTHER JURISDICTION.

     (f) Construction. As used in this Agreement, “or” will not be deemed exclusive;
inclusion of items in a list will not be deemed to exclude similar items; terms that imply
gender will include all genders; defined terms will have their meanings in both the singular
and the plural case; and “include” and its correlatives mean to include without limitation.

     (g) Investor. For the avoidance of doubt, (i) “Investor” shall mean each of
High River Limited Partnership, Icahn Partners LP, Icahn Partners Master Fund LP, Icahn
Partners Master Fund II LP and Icahn Partners Master Fund III LP, (ii) for purposes of

River Limited Partnership, Icahn Partners Master Fund LP, Icahn Partners Master Fund II LP
and Icahn Partners Master Fund III LP are intended third party beneficiaries of this
Agreement.
