Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver
such certificate (and to issue such Warrant Shares or credit such Holder’s balance account with
DTC) shall terminate, or (B) promptly honor its obligation to deliver to the Holder a certificate
or certificates representing such Warrant Shares or credit such Holder’s balance account with DTC
and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the
product of (1) such number of shares of Common Stock, times (2) the VWAP on the date of exercise.

               v. No Fractional Shares or Scrip. No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share
which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at
its election, either pay a cash adjustment in respect of such final fraction in an amount equal to
such fraction multiplied by the Exercise Price or round up to the next whole share.

               vi. Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares shall be
made without charge to the Holder for any issue or transfer tax or other incidental expense in
respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the
Company, and such certificates shall be issued in the name of the Holder or in such
name or names as may be directed by the Holder; provided, however, that in the
event certificates for Warrant Shares are to be issued in a name other than the name of the Holder,
this

-3-

 

Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached
hereto duly executed by the Holder and the Company may require, as a condition thereto, the payment
of a sum sufficient to reimburse it for any transfer tax incidental thereto.

               vii. Closing of Books. The Company will not close its stockholder books or records in
any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

          d) Holder’s Exercise Limitations. The Company shall not effect any exercise of this
Warrant, and a Holder shall not have the right to exercise any portion of this Warrant, pursuant to
Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise as
set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates,
and any other Persons (as defined below) acting as a group together with the Holder or any of the
Holder’s Affiliates), would beneficially own in excess of the Beneficial Ownership Limitation (as
defined below). For purposes of the foregoing sentence, the number of shares of Common Stock
beneficially owned by the Holder and its Affiliates shall include the number of shares of Common
Stock issuable upon exercise of this Warrant with respect to which such determination is being
made, but shall exclude the number of shares of Common Stock which would be issuable upon (i)
exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or
any of its Affiliates and (ii) exercise or conversion of the unexercised or nonconverted portion of
any other securities of the Company (including, without limitation, any other common stock
equivalents) subject to a limitation on conversion or exercise analogous to the limitation
contained herein beneficially owned by the Holder or any of its Affiliates. Except as set forth in
the preceding sentence, for purposes of this Section 2(d), beneficial ownership shall be calculated
in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated
thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder
that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is
solely responsible for any schedules required to be filed in accordance therewith. To the extent
that the limitation contained in this Section 2(d) applies, the determination of whether this
Warrant is exercisable (in relation to other securities owned by the Holder together with any
Affiliates) and of which portion of this Warrant is exercisable shall be in the sole discretion of
the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s
determination of whether this Warrant is exercisable (in relation to other securities owned by the
Holder together with any Affiliates) and of which portion of this Warrant is exercisable, in each
case subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to
verify or confirm the accuracy of such determination. In addition, a determination as to any group
status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange
Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(d), in
determining the number of outstanding shares of Common Stock, a Holder may rely on the number of
outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual
report filed with the Commission, as the case may be, (B) a more recent public announcement by the
Company or (C) a more recent written notice by the Company or its transfer agent setting forth the
number of shares of Common Stock outstanding. Upon the
written or oral request of a Holder, the Company shall within three trading days confirm
orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any

-4-

 

case, the number of outstanding shares of Common Stock shall be determined after giving effect to
the conversion or exercise of securities of the Company, including this Warrant, by the Holder or
its Affiliates since the date as of which such number of outstanding shares of Common Stock was
reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of
the Common Stock outstanding immediately after giving effect to the issuance of shares of Common
Stock issuable upon exercise of this Warrant. The Holder, upon not less than 61 days’ prior notice
to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this
Section 2(d), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the
number of shares of the Common Stock outstanding immediately after giving effect to the issuance of
shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions of this
Section 2(d) shall continue to apply. Any such increase or decrease will not be effective until
the 61st day after such notice is delivered to the Company. The provisions of this
paragraph shall be construed and implemented in a manner otherwise than in strict conformity with
the terms of this Section 2(d) to correct this paragraph (or any portion hereof) which may be
defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to
make changes or supplements necessary or desirable to properly give effect to such limitation. The
limitations contained in this paragraph shall apply to a successor holder of this Warrant.

     Section 3. Certain Adjustments.

          a) Stock Dividends and Splits. If the Company, at any time while this Warrant is
outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares
of its Common Stock or any other equity or equity equivalent securities payable in shares of Common
Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the
Company upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock into a
larger number of shares, (iii) combines (including by way of reverse stock split) outstanding
shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification of
shares of the Common Stock any shares of capital stock of the Company, then in each case the
Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of
shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such
event and of which the denominator shall be the number of shares of Common Stock outstanding
immediately after such event, and the number of shares issuable upon exercise of this Warrant shall
be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain
unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately
after the record date for the determination of stockholders entitled to receive such dividend or
distribution and shall become effective immediately after the effective date in the case of a
subdivision, combination or re-classification.

          b) Pro Rata Distributions. If the Company, at any time while this Warrant is
outstanding, shall distribute to all holders of Common Stock (and not to the Holders) evidences of
its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe
for or purchase any security other than the Common Stock (which shall be subject to Section 3(b)),
then in each such case the Exercise Price shall be adjusted by multiplying the
Exercise Price in effect immediately prior to the record date fixed for determination of
stockholders entitled to receive such distribution by a fraction of which the denominator shall be

-5-

 

the VWAP determined as of the record date mentioned above, and of which the numerator shall be such
VWAP on such record date less the then per share fair market value at such record date of the
portion of such assets or evidence of indebtedness so distributed applicable to one outstanding
share of the Common Stock as determined by the Company’s Board of Directors in good faith. In
either case the adjustments shall be described in a statement provided to the Holder of the portion
of assets or evidences of indebtedness so distributed or such subscription rights applicable to one
share of Common Stock. Such adjustment shall be made whenever any such distribution is made and
shall become effective immediately after the record date mentioned above.

          c) Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the
Company, directly or indirectly, in one or more related transactions effects any merger or
consolidation of the Company with or into another Person in which the Company is not the surviving
entity or the stockholders of the Company immediately prior to such merger or consolidation do not
own, directly or indirectly, at least 50% of the outstanding voting securities of the surviving
entity, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment,
transfer, conveyance or other disposition of all or substantially all of its assets in one or a
series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or
exchange offer (whether by the Company or another Person) is completed pursuant to which all or
substantially all of the holders of Common Stock are permitted to sell, tender or exchange their
shares for other securities, cash or property and has been accepted by the holders of 50% or more
of the outstanding Common Stock, or (iv) the Company, directly or indirectly, in one or more
related transactions effects any reclassification, reorganization or recapitalization of the Common
Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted
into or exchanged for other securities, cash or property (other than as a result of a subdivision
or combination of shares of Common Stock covered by Section 3(a) above), (each a “Fundamental
Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the
right to receive, for each Warrant Share that would have been issuable upon such exercise
immediately prior to the occurrence of such Fundamental Transaction, at the option of the Holder
(without regard to any limitation in Section 2(d) on the exercise of this Warrant), the number of
shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the
surviving corporation, and any additional consideration (the “Alternate Consideration”)
receivable as a result of such Fundamental Transaction by a holder of the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to such Fundamental
Transaction (without regard to any limitation in Section 2(d) on the exercise of this Warrant).
For purposes of any such exercise, the determination of the Exercise Price shall be appropriately
adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company
shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner
reflecting the relative value of any different components of the Alternate Consideration. If
holders of Common Stock are given any choice as to the securities, cash or property to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate
Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction.
Notwithstanding anything to the contrary, in
the event of a Fundamental Transaction other than one in which a Successor Entity (as defined
below) that is a publicly traded corporation whose stock is quoted or listed for trading on an

-6-

 

Eligible Market (as defined below) assumes this Warrant such that the Warrant shall be exercisable
for the publicly traded Common Stock of such Successor Entity, the Company or any Successor Entity
shall, at the Holder’s option, exercisable at any time concurrently with, or within 30 days after,
the consummation of the Fundamental Transaction, purchase this Warrant from the Holder by paying to
the Holder an amount of cash equal to the Black Scholes Value of the remaining unexercised portion
of this Warrant on the date of the consummation of such Fundamental Transaction. As used herein
(w) “Black Scholes Value” means the value of this Warrant based on the Black and Scholes
Option Pricing Model obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”)
determined as of the day of consummation of the applicable Fundamental Transaction for pricing
purposes and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a
period equal to the time between the date of the public announcement of the applicable Fundamental
Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and
the 100 day volatility obtained from the HVT function on Bloomberg as of the trading day
immediately following the public announcement of the applicable Fundamental Transaction, (C) the
underlying price per share used in such calculation shall be the sum of the price per share being
offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in
such Fundamental Transaction and (D) a remaining option time equal to the time between the date of
the public announcement of the applicable Fundamental Transaction and the Termination Date, (1)
“Successor Entity” means the Person (or, if so elected by the Holder, the Parent Entity (as
defined below)) formed by, resulting from or surviving any Fundamental Transaction or the Person
(or, if so elected by the Holder, the Parent Entity) with which such Fundamental Transaction shall
have been entered into, (2) “Eligible Market” means the NYSE Amex, The NASDAQ Capital
Market, The NASDAQ Global Market, The NASDAQ Global Select Market, the New York Stock Exchange or
the OTC Bulletin Board (or any successors to any of the foregoing), (3) “Parent Entity” of
a Person means an entity that, directly or indirectly, controls the applicable Person and whose
common stock or equivalent equity security is quoted or listed on an Eligible Market, or, if there
is more than one such Person or Parent Entity, the Person or Parent Entity with the largest public
market capitalization as of the date of consummation of the Fundamental Transaction. The terms of
any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring
any such successor or surviving entity to comply with the provisions of this Section 3(e) and
insuring that this Warrant (or any such replacement security) will be similarly adjusted upon any
subsequent transaction analogous to a Fundamental Transaction, and (4) “Person” means an
individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an
unincorporated organization, any other entity and a government or any department or agency thereof.

          d) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price
pursuant to paragraph (a) and (e) of this Section, the number of Warrant Shares that may be
purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that
after such adjustment the aggregate Exercise Price payable hereunder for the increased or decreased
number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately
prior to such adjustment.

          e) Subsequent Equity Sales.

-7-

 

               i. Except as provided in subsection (e)(iii) hereof, if and whenever the Company shall issue
or sell, or is, in accordance with any of subsections (e)(ii)(l) through (e)(ii)(7) hereof, deemed
to have issued or sold, any shares of Common Stock for no consideration or for a consideration per
share less than the Exercise Price in effect immediately prior to the time of such issue or sale,
then and in each such case (a “Trigger Issuance”) the then-existing Exercise Price shall be
reduced as of the close of business on the effective date of the Trigger Issuance, to a price
determined as follows:

	 	 	 

	Adjusted Exercise Price =

	 	(A x B) + D
	 

	 	 
	 

	 	A+C

where

“A” equals the number of shares of Common Stock outstanding, including
Additional Shares of Common Stock (as defined below) deemed to be issued
hereunder, immediately preceding such Trigger Issuance;

“B” equals the Exercise Price in effect immediately preceding such Trigger
Issuance;

“C” equals the number of Additional Shares of Common Stock issued or deemed
issued hereunder as a result of the Trigger Issuance; and

“D” equals the aggregate consideration, if any, received or deemed to be
received by the Company upon such Trigger Issuance;

               provided, however, that in no event shall the Exercise Price after giving effect to such
Trigger Issuance be greater than the original Exercise Price.

          For purposes of this subsection (e), “Additional Shares of Common Stock” shall mean
all shares of Common Stock issued by the Company or deemed to be issued pursuant to this subsection
(e), other than Exempt Issuances (as defined below).

               ii. For purposes of this subsection 3(e), the following subsections (e)(ii)(l) to (e)(ii)(7)
shall also be applicable:

                    (1) Issuance of Rights or Options. In case at any time the Company shall in any manner
grant (directly and not by assumption in a merger or otherwise) any warrants or other rights to
subscribe for or to purchase, or any options for the purchase of, Common Stock or any stock or
security convertible into or exchangeable for Common Stock (such warrants, rights or options being
called “Options” and such convertible or exchangeable stock or securities being called
“Convertible Securities”), whether or not such Options or the right to convert or exchange
any such Convertible Securities are immediately exercisable, and the price per share for which
Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of
such Convertible Securities (determined by dividing (i) the
sum (which sum shall constitute the applicable consideration) of (x) the total amount, if any,
received or receivable by the Company as consideration for the granting of such Options, plus

-8-

 

(y)
the aggregate amount of additional consideration payable to the Company upon the exercise of all
such Options, plus (z), in the case of such Options which relate to Convertible Securities, the
aggregate amount of additional consideration, if any, payable upon the issue or sale of such
Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum
number of shares of Common Stock issuable upon the exercise of such Options or upon the conversion
or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be
less than the Exercise Price in effect immediately prior to the time of the granting of such
Options, then the total number of shares of Common Stock issuable upon the exercise of such Options
or upon conversion or exchange of the total amount of such Convertible Securities issuable upon the
exercise of such Options shall be deemed to have been issued for such price per share as of the
date of granting of such Options or the issuance of such Convertible Securities and thereafter
shall be deemed to be outstanding for purposes of adjusting the Exercise Price. Except as otherwise
provided in subsection 3(e)(ii)(3), no adjustment of the Exercise Price shall be made upon the
actual issue of such Common Stock or of such Convertible Securities upon exercise of such Options
or upon the actual issue of such Common Stock upon conversion or exchange of such Convertible
Securities.

                    (2) Issuance of Convertible Securities. In case the Company shall in any manner issue
(directly and not by assumption in a merger or otherwise) or sell any Convertible Securities,
whether or not the rights to exchange or convert any such Convertible Securities are immediately
exercisable, and the price per share for which Common Stock is issuable upon such conversion or
exchange (determined by dividing (i) the sum (which sum shall constitute the applicable
consideration) of (x) the total amount received or receivable by the Company as consideration for
the issue or sale of such Convertible Securities, plus (y) the aggregate amount of additional
consideration, if any, payable to the Company upon the conversion or exchange thereof, by (ii) the
total number of shares of Common Stock issuable upon the conversion or exchange of all such
Convertible Securities) shall be less than the Exercise Price in effect immediately prior to the
time of such issue or sale, then the total maximum number of shares of Common Stock issuable upon
conversion or exchange of all such Convertible Securities shall be deemed to have been issued for
such price per share as of the date of the issue or sale of such Convertible Securities and
thereafter shall be deemed to be outstanding for purposes of adjusting the Exercise Price, provided
that (a) except as otherwise provided in subsection 3(e)(ii)(3), no adjustment of the Exercise
Price shall be made upon the actual issuance of such Common Stock upon conversion or exchange of
such Convertible Securities and (b) no further adjustment of the Exercise Price shall be made by
reason of the issue or sale of Convertible Securities upon exercise of any Options to purchase any
such Convertible Securities for which adjustments of the Exercise Price have been made pursuant to
the other provisions of subsection 3(e).

                    (3) Change in Option Price or Conversion Rate. Upon the happening of any of the
following events, namely, if the purchase price provided for in any Option referred to in
subsection 3(e)(ii)(l), the additional consideration, if any, payable upon the conversion or
exchange of any Convertible Securities referred to in subsections 3(e)(ii)(l) or 3(e)(ii)(2), or
the rate at which Convertible Securities referred to in subsections 3(e)(ii)(l) or
3(e)(ii)(2) are convertible into or exchangeable for Common Stock shall change at any time
(including, but not limited to, changes under or by reason of provisions designed to protect

-9-

 

against dilution), the Exercise Price in effect at the time of such event shall forthwith be
readjusted to the Exercise Price which would have been in effect at such time had such Options or
Convertible Securities still outstanding provided for such changed purchase price, additional
consideration or conversion rate, as the case may be, at the time initially granted, issued or
sold. On the termination of any Option for which any adjustment was made pursuant to this
subsection 3(e) or any right to convert or exchange Convertible Securities for which any adjustment
was made pursuant to this subsection 3(e) (including, without limitation, upon the redemption or
purchase for consideration of such Convertible Securities by the Company), the Exercise Price then
in effect hereunder shall forthwith be changed to the Exercise Price which would have been in
effect at the time of such termination had such Option or Convertible Securities, to the extent
outstanding immediately prior to such termination, never been issued.

                    (4) Stock Dividends. Subject to the provisions of this Section 3(e), in case the
Company shall declare a dividend or make any other distribution upon any stock of the Company
(other than the Common Stock) payable in Common Stock, Options or Convertible Securities, then any
Common Stock, Options or Convertible Securities, as the case may be, issuable in payment of such
dividend or distribution shall be deemed to have been issued or sold without consideration.

                    (5) Consideration for Stock. In case any shares of Common Stock, Options or
Convertible Securities shall be issued or sold for cash, the consideration received therefor shall
be deemed to be the gross amount received by the Company therefor. In case any shares of Common
Stock, Options or Convertible Securities shall be issued or sold for a consideration other than
cash, the amount of the consideration other than cash received by the Company shall be deemed to be
the fair value of such consideration as determined in good faith by the Board of Directors of the
Company. In case any Options shall be issued in connection with the issue and sale of other
securities of the Company, together comprising one integral transaction in which no specific
consideration is allocated to such Options by the parties thereto, such Options shall be deemed to
have been issued for such consideration as determined in good faith by the Board of Directors of
the Company. If Common Stock, Options or Convertible Securities shall be issued or sold by the
Company and, in connection therewith, other Options or Convertible Securities (the “Additional
Rights”) are issued, then the consideration received or deemed to be received by the Company
shall be reduced by the fair market value of the Additional Rights (as determined using the
Black-Scholes option pricing model or another method mutually agreed to by the Company and the
Holder). The Board of Directors of the Company shall respond promptly, in writing, to an inquiry
by the Holder as to the fair market value of the Additional Rights. In the event that the Board of
Directors of the Company and the Holder are unable to agree upon the fair market value of the
Additional Rights, the Company and the Holder shall jointly select an appraiser who is experienced
in such matters. The decision of such appraiser shall be final and conclusive, and the cost of
such appraiser shall be borne evenly by the Company and the Holder.

                    (6) Record Date. In case the Company shall take a record of the holders of its Common
Stock for the purpose of entitling them (i) to receive a dividend or other
distribution payable in Common Stock, Options or Convertible Securities or (ii) to subscribe
for or purchase Common Stock, Options or Convertible Securities, then such record date shall be

-10-

 

deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued
or sold upon the declaration of such dividend or the making of such other distribution or the date
of the granting of such right of subscription or purchase, as the case may be.

                    (7) Treasury Shares. The number of shares of Common Stock outstanding at any given
time shall not include shares owned or held by or for the account of the Company or any of its
wholly-owned subsidiaries, and the disposition of any such shares (other than the cancellation or
retirement thereof) shall be considered an issue or sale of Common Stock for the purpose of this
subsection (e).

               iii. Exempt Issuance. Notwithstanding the foregoing, no adjustment will be made under
this paragraph (e) in respect of an Exempt Issuance. For the purposes of this Warrant, “Exempt
Issuance” means the issuance of (a) shares of Common Stock, common stock equivalents,
restricted stock units or other Options to employees, consultants officers or directors of the
Company pursuant to any existing or future stock option, restricted stock, stock purchase or other
equity compensation plan duly adopted for such purpose, by a majority of the non-employee members
of the Board of Directors or a majority of the members of a committee of non-employee directors
established for such purpose, and the issuance of Common Stock in respect of such common stock
equivalents, restricted stock units or other Options, (b) securities (including Common Stock and
common stock equivalents) upon the exercise, conversion or exchange of securities (including
Convertible Securities and Options) issued and outstanding on the date hereof, including the
Warrants, provided that such securities have not been amended since date hereof to increase the
number of such securities or to decrease the exercise price, exchange price or conversion price of
such securities, (c) securities issued pursuant to acquisitions or strategic transactions approved
by a majority of the disinterested directors of the Company, provided that any such issuance shall
only be to a Person (or to the equityholders of a Person) that the Company’s Board of Directors
determines in good faith is, itself or through its subsidiaries, an operating company or an owner
of an asset in a business synergistic with the business of the Company and shall provide to the
Company additional benefits in addition to the investment of funds, but shall not, for the purposes
of this clause (c), include a transaction in which the Company is issuing securities primarily for
the purpose of raising capital or to an entity whose primary business is investing in securities,
and (d) the issuance of securities in a transaction described in Section 3(a) or 3(b) above.

               iv. Upon any adjustment to the Exercise Price pursuant to this Section 3(e), the number of
Warrant Shares purchasable hereunder shall be adjusted by multiplying such number by a fraction,
the numerator of which shall be the Exercise Price in effect immediately prior to such adjustment
and the denominator of which shall be the Exercise Price in effect immediately thereafter.

          f) Calculations. All calculations under this Section 3 shall be made to the nearest
cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the
number of shares of Common Stock deemed to be issued and outstanding as of a given date
shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any)
issued and outstanding.

-11-

 

          g) Notice to Holder.

               i. Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to
any provision of this Section 3, the Company shall promptly mail to the Holder a notice setting
forth the Exercise Price after such adjustment and setting forth a brief statement of the facts
requiring such adjustment.

               ii. Notice to Allow Exercise by Holder. After the Issue Date, (A) the Company shall
declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the
Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock,
(C) the Company shall authorize the granting to all holders of the Common Stock rights or warrants
to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the
approval of any stockholders of the Company shall be required in connection with any
reclassification of the Common Stock, any consolidation or merger to which the Company is a party,
any sale or transfer of all or substantially all of the assets of the Company, or any compulsory
share exchange whereby the Common Stock is converted into other securities, cash or property, or
(E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up
of the affairs of the Company, then, in each case, the Company shall cause to be mailed to the
Holder at its last address as it shall appear upon the Warrant Register of the Company, at least 20
calendar days prior to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such dividend,
distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of
which the holders of the Common Stock of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which such reclassification,
consolidation, merger, sale, transfer or share exchange is expected to become effective or close,
and the date as of which it is expected that holders of the Common Stock of record shall be
entitled to exchange their shares of the Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange;
provided that the failure to mail such notice or any defect therein or in the mailing thereof shall
not affect the validity of the corporate action required to be specified in such notice. To the
extent that any notice provided hereunder constitutes, or contains, material, non-public
information regarding the Company or any of its subsidiaries, the Company shall simultaneously file
such notice with the Commission pursuant to a Current Report on Form 8-K. The Holder shall remain
entitled to exercise this Warrant during the period commencing on the date of such notice to the
effective date of the event triggering such notice except as may otherwise be expressly set forth
herein.

     Section 4. Transfer of Warrant.

          a) Transferability. Subject to compliance with any applicable securities laws, this
Warrant and all rights hereunder (including, without limitation, any registration rights) are
transferable, in whole or in part, upon surrender of this Warrant at the principal office of the
Company or its designated agent, together with a written assignment of this Warrant
substantially in the form attached hereto duly executed by the Holder or its agent or attorney
and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such
surrender and, if required, such payment, the Company shall execute and deliver a new Warrant

-12-

 

or
Warrants in the name of the assignee or assignees, as applicable, and in the denomination or
denominations specified in such instrument of assignment, and shall issue to the assignor a new
Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be
cancelled. The Warrant, if properly assigned in accordance herewith, may be exercised by a new
holder for the purchase of Warrant Shares without having a new Warrant issued.

          b) New Warrants. This Warrant may be divided or combined with other Warrants upon
presentation hereof at the aforesaid office of the Company, together with a written notice
specifying the names and denominations in which new Warrants are to be issued, signed by the Holder
or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be
involved in such division or combination, the Company shall execute and deliver a new Warrant or
Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such
notice. All Warrants issued on transfers or exchanges shall be dated the initial issuance date set
forth on the first page of this Warrant and shall be identical with this Warrant except as to the
number of Warrant Shares issuable pursuant thereto.

          c) Warrant Register. The Company shall register this Warrant, upon records to be
maintained by the Company for that purpose (the “Warrant Register”), in the name of the
record Holder hereof from time to time. The Company may deem and treat the registered Holder of
this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any
distribution to the Holder, and for all other purposes, absent actual notice to the contrary. Upon
thirty (30) days notice to the Holder, the Company may appoint a warrant agent to maintain the
Warrant Register.

     Section 5. Miscellaneous.

          a) No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder
to any voting rights, dividends or other rights as a stockholder of the Company prior to the
exercise hereof as set forth in Section 2(c)(i).

          b) Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon
receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or
mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of
loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the
case of the Warrant, shall not include the posting of any bond), and upon surrender and
cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver
a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such
Warrant or stock certificate.

          c) Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of
any action or the expiration of any right required or granted herein shall not be a business day,
then, such action may be taken or such right may be exercised on the next succeeding business day.

          d) Authorized Shares. The Company covenants that, during the period the Warrant is
outstanding, it will reserve from its authorized and unissued Common Stock a

-13-

 

sufficient number of
shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights
under this Warrant. The Company further covenants that its issuance of this Warrant shall
constitute full authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant Shares upon the
exercise of the purchase rights under this Warrant. The Company will take all such reasonable
action as may be necessary to assure that such Warrant Shares may be issued as provided herein
without violation of any applicable law or regulation, or of any requirements of the Trading Market
upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may
be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise
of the purchase rights represented by this Warrant and payment for such Warrant Shares in
accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from
all taxes, liens and charges created by the Company in respect of the issue thereof (other than
taxes in respect of any transfer occurring contemporaneously with such issue).

          Except and to the extent as waived or consented to by the Holder, the Company shall not by any
action, including, without limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities
or any other voluntary action, avoid or seek to avoid the observance or performance of any of the
terms of this Warrant, but will at all times in good faith assist in the carrying out of all such
terms and in the taking of all such actions as may be necessary or appropriate to protect the
rights of Holder as set forth in this Warrant against impairment. Without limiting the generality
of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the
amount payable therefor upon such exercise immediately prior to such increase in par value, (ii)
take all such action as may be necessary or appropriate in order that the Company may validly and
legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and
(iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents
from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the
Company to perform its obligations under this Warrant.

          Before taking any action which would result in an adjustment in the number of Warrant Shares
for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such
authorizations or exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

          e) Jurisdiction. All questions concerning the construction, validity, enforcement and
interpretation of this Warrant shall be determined in accordance with
the laws of the State of Oklahoma.

          f) Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the
exercise of this Warrant, if not registered, and the Holder does not utilize cashless exercise,
will have restrictions upon resale imposed by state and federal securities laws.

          g) Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise
any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise
prejudice Holder’s rights, powers or remedies. Without limiting any other provision of

-14-

 

this
Warrant, if the Company willfully and knowingly fails to comply with any provision of this Warrant,
which results in any material damages to the Holder, the Company shall pay to Holder such amounts
as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable
attorneys’ fees, including those of appellate proceedings, incurred by Holder in collecting any
amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.

          h) Notices. The Company shall provide Holder with prompt written notice of all
actions taken pursuant to this Warrant. Whenever notice is required to be given under this Warrant,
unless otherwise provided herein, such notice shall be given in writing, will be mailed (i) if
within the domestic United States by first-class registered or certified airmail, or nationally
recognized overnight express courier, postage prepaid, or by facsimile or (ii) if delivered from
outside the United States, by International Federal Express or facsimile, and (iii) will be deemed
given (A) if delivered by first-class registered or certified mail domestic, three business days
after so mailed, (B) if delivered by nationally recognized overnight carrier, one business day
after so mailed, (C) if delivered by International Federal Express, two business days after so
mailed and (D) if delivered by facsimile, upon electronic confirmation of receipt, and will be
delivered and addressed as follows:

(2) if to the Holder, at the address of the Holder appearing on the books of the

Company.

          i) Limitation of Liability. No provision hereof, in the absence of any affirmative
action by Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of
the rights or privileges of Holder, shall give rise to any liability of Holder for the purchase
price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by
the Company or by creditors of the Company.

          j) Remedies. The Holder, in addition to being entitled to exercise all rights granted
by law, including recovery of damages, will be entitled to specific performance of its

-15-

 

rights under
this Warrant. The Company agrees that monetary damages would not be adequate compensation for any
loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to
waive and not to assert the defense in any action for specific performance that a remedy at law
would be adequate.

          k) Successors and Assigns. Subject to applicable securities laws, this Warrant and
the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the
successors and permitted assigns of the Company and the successors and permitted assigns of Holder.
The provisions of this Warrant are intended to be for the benefit of any Holder from time to time
of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

          l) Amendment. This Warrant may be modified or amended or the provisions hereof waived
with the written consent of the Company and the Holder.

         m) Severability. Wherever possible, each provision of this Warrant shall be
interpreted in such manner as to be effective and valid under applicable law, but if any provision
of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of
such provisions or the remaining provisions of this Warrant.

          n) Headings. The headings used in this Warrant are for the convenience of reference
only and shall not, for any purpose, be deemed a part of this Warrant.
