HARVEST NATURAL RESOURCES, INC.

COMMON STOCK PURCHASE WARRANT

     Harvest Natural Resources, Inc., a Delaware corporation (together with any corporation which
shall succeed to or assume the obligations of Harvest Natural Resources, Inc. hereunder, the
“Company”), hereby certifies that, for value received, MSD Energy Investments Private II,
LLC (the “Investor”), or its assigns, is entitled, subject to the terms set forth below, to
purchase from the Company at any time during the Exercise Period (as defined in Section 12 hereof)
up to 4,400,000 fully paid and non-assessable shares of Common Stock (as defined in Section 12
hereof), at a purchase price per share equal to the Exercise Price (as defined in Section 12
hereof). The number of shares of Common Stock for which this Warrant is exercisable and the
Exercise Price are subject to adjustment as provided herein.

     This Warrant is issued pursuant to the Warrant Purchase Agreement (as amended and in effect
from time to time, the “Warrant Purchase Agreement”), dated as of October
28, 2010, between the Company and the initial purchaser named therein, a copy of which is on file
at the principal office of the Company. The holder of this Warrant shall be entitled to all of the
benefits and shall be subject to all of the obligations of the Warrant Purchase Agreement.

1. DEFINITIONS. Terms defined in the Warrant Purchase Agreement and not otherwise
defined herein are used herein with the meanings so defined. Certain terms are used in this
Warrant as specifically defined in Section 12 hereof.

2. EXERCISE OF WARRANT.

     2.1. Exercise. This Warrant may be exercised prior to its expiration pursuant to
Section 2.5 hereof by the holder hereof at any time or from time to time during the Exercise
Period, by surrender of this Warrant, with the form of subscription attached hereto duly executed
by such holder, to the Company at its principal office, indicating such holder’s election to
exercise this Warrant as to a specified number of shares pursuant to the net exercise provisions of
Section 2.2. This Warrant shall be deemed exercised for all purposes as of the close of business
on the day on which the holder has delivered this Warrant and the subscription form to the Company,
regardless of when the Company issues the certificates evidencing the shares issuable upon such
exercise. In the event the Warrant is not exercised in full, the Company, at its expense, will forthwith issue and
deliver to or

 

 

upon the order of the holder hereof a new Warrant or Warrants of like tenor, in the
name of the holder hereof or as such holder (upon payment by such holder of any applicable transfer
taxes) may request, calling in the aggregate on the face or faces thereof for the number of shares
of Common Stock equal (without giving effect to any adjustment therein) to the number of such
shares called for on the face of this Warrant minus the number of such shares (without giving
effect to any adjustment therein) for which this Warrant shall have been exercised.

     2.2. Net Exercise. The holder may elect to exercise this Warrant at any time or
from time to time, by receiving shares of Common Stock equal to the number of shares determined
pursuant to the following formula:

	 	 	 	 	 	 	 	 	 

	 

	 	X
	 	=
	 	Y (A - B)
 

A
	 	 

     where,

	 	X = 	 	the number of shares of Common Stock to be issued to Holder;
	 
	 	Y = 	 	the number of shares of Common Stock as to which this Warrant is to be
exercised (as indicated on the subscription form);
	 
	 	A = 	 	the closing price on the Principal Market of the Common Stock calculated as
of the Trading Day immediately preceding the date of exercise; and
	 
	 	B = 	 	the Exercise Price.

     2.3. Antitrust Notification. If the holder of this Warrant determines, in its
sole judgment upon the advice of counsel, that an exercise of this Warrant pursuant to the terms
hereof would be subject to the provisions of the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended (the “HSR Act”), the Company shall, within seven (7) business days after
receiving notice from such holder of the applicability of the HSR Act, file with the United States
Federal Trade Commission (the “FTC”) and the United States Department of Justice (the
“DOJ”) the notification and report form and any supplemental information required to be
filed by it pursuant to the HSR Act in connection with the exercise of this Warrant. Any such
notification and report form and supplemental information will be in full compliance with the
requirements of the HSR Act. The Company will furnish to such holder promptly (but in no event
more than five (5) business days) such information and assistance as such holder may reasonably
request in connection with the preparation of any filing or submission required to be filed by such
holder under the HSR Act. The Company shall respond promptly after receiving any inquiries or
requests for additional information from the FTC or the DOJ (and in no event more than three (3)
business days after receipt of such inquiry or request). The Company shall keep such holder
apprised periodically and at such holder’s request of the status of any communications with, and
any inquiries or requests for additional information from, the FTC or the DOJ. The Company shall
bear all filing or other fees required to be paid by the Company and such holder (or the “ultimate
parent entity” of such holder, if any) under the HSR Act or any other applicable law in connection
with such filings and all costs and expenses (including, without limitation, attorneys’ fees and
expenses) incurred by the Company and such holder in connection with the preparation of such
filings and responses to inquiries or requests. In the event that this Section 2.3 is applicable
to any exercise of this Warrant, the purchase by such holder of the Exercise Shares subject to such
exercise, and the payment by such holder of the Exercise Price therefor, shall be subject to the
expiration or earlier termination of the waiting period under the HSR Act (with the
exercise date of this Warrant being deemed to be the date immediately following the date of such
expiration or early termination).

-2-

 

     2.4. Termination. This Warrant shall terminate upon the earlier to occur of (i)
exercise in full or (ii) the expiration of the Exercise Period.

3. REGISTRATION RIGHTS. The holder of this Warrant has certain rights to
require the Company to register the Warrant Shares under the Securities Act and any blue sky or
securities laws of any jurisdictions within the United States at the time and in the manner
specified in the Warrant Purchase Agreement.

4. DELIVERY OF STOCK CERTIFICATES ON EXERCISE.
As soon as practicable after any exercise of this Warrant and in any event within three (3) Trading
Days thereafter, the Company shall, at its expense (including the payment by it of any applicable
issue or stamp taxes), cause to be issued in the name of and delivered to the holder, or as the
holder may direct, a certificate or certificates evidencing the number of fully paid and
nonassessable shares of Common Stock (or Other Securities, as applicable) (which number shall be
rounded up to the nearest whole share in the event any fractional share may otherwise be issuable
upon such exercise) to which the holder shall be entitled on such exercise, in such denominations
as may be requested by the holder, which certificate or certificates shall be free of restrictive
and trading legends (except for any such legends as may be required under the Securities Act). In
lieu of delivering physical certificates for the shares of Common Stock (or Other Securities)
issuable upon any exercise of this Warrant, provided the Company’s transfer agent is participating
in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer (“FAST”)
program or a similar program, upon request of the holder, the Company shall use commercially
reasonable efforts to cause its transfer agent to electronically transmit such shares of Common
Stock (or Other Securities) issuable upon exercise of this Warrant to the holder (or its designee),
by crediting the account of the holder’s (or such designee’s) broker with DTC through its Deposit
Withdrawal Agent Commission system (provided that the same time periods herein as for stock
certificates shall apply) as instructed by the holder (or its designee).

5. ADJUSTMENT FOR DIVIDENDS, DISTRIBUTIONS AND
RECLASSIFICATIONS.

     5.1. Distribution of Assets; Spin-Off. If the Company shall declare or make any
dividend or other distribution of its assets (or rights to acquire its assets) to holders of Common
Stock, by way of return of capital or otherwise (including, without limitation, any distribution of
cash, stock or other securities, property or options by way of a Spin-Off, dividend,
reclassification, corporate rearrangement or other similar transaction, but excluding cash
dividends adjustments in respect of which are provided for in Section 5.2 hereof and excluding
stock dividends or stock splits adjustments in respect of which are provided for in Section 7
hereof) (a “Distribution”), at any time after the issuance of this Warrant, then, in each
such case:

          (a) (i) the Exercise Price in effect immediately prior to the close of business on the
record date fixed for the determination of holders of Common Stock entitled to receive the
Distribution shall be reduced, effective as of the close of business on such record date, to a
price determined by multiplying such Exercise Price by a fraction of which:

          (A) the numerator shall be the Market Price of the Common Stock on the Trading Day
immediately preceding such record date minus the Fair Market Value of the Distribution
applicable to one share of Common Stock, and

-3-

 

          (B) the denominator shall be the Market Price of the Common Stock on the Trading
Day immediately preceding such record date;

and (ii) the number of Exercise Shares obtainable upon exercise of this Warrant shall be increased
to a number of shares equal to the number of shares of Common Stock obtainable immediately prior to
the close of business on the record date fixed for the determination of holders of Common Stock
entitled to receive the Distribution multiplied by the reciprocal of the fraction
set forth in the immediately preceding clause (i) of this Section 5.1(a); and

          (b) Notwithstanding the provisions of the foregoing clause (a), in the event of a Spin-Off
in which the Distribution is of common stock of a subsidiary of the Company, then (i) the Exercise
Price in effect immediately prior to the close of business on the record date fixed for the
determination of holders of Common Stock entitled to receive such Distribution shall be reduced,
effective as of the close of business on such record date, to a price determined by multiplying
such Exercise Price by a fraction of which:

          (A) the numerator shall be the Market Price of the Common Stock on the Trading Day
immediately preceding such record date minus the Fair Market Value of the Distribution
applicable to one share of Common Stock, and

          (B) the denominator shall be the Market Price of the Common Stock on the Trading
Day immediately preceding such record date;

and (ii) the number of Exercise Shares obtainable upon exercise of this Warrant shall be increased
to a number of shares equal to the number of shares of Common Stock obtainable immediately prior to
the close of business on the record date fixed for the determination of holders of Common Stock
entitled to receive such Distribution multiplied by the reciprocal of the fraction set forth in the
immediately preceding clause (i) of this Section 5.1(b); and (iii) the holder of this Warrant shall
receive an additional warrant to purchase common stock of such company, the terms of which shall be
identical to those of this Warrant, except that such warrant shall be exercisable into the number
of shares of common stock of such company that would have been issuable or distributed to the
holder of this Warrant pursuant to the Distribution had the holder exercised this Warrant for cash
for the full number of shares of Common Stock on the face of this Warrant (notwithstanding the
requirement that this Warrant be exercised pursuant to the net exercise provisions of Section 2.2)
immediately prior to such record date and with an exercise price equal to the amount by which the
Exercise Price of this Warrant was decreased with respect to the Distribution pursuant to the terms
of the preceding clause (i) of this Section 5.1(b).

     5.2. Cash Dividends. In case at any time or from time to time, the holders of Common
Stock shall have received, or (on or after the record date fixed for the determination of
shareholders eligible to receive) shall have become entitled to receive, any cash dividend or
distribution, then (a) the Exercise Price in effect immediately prior to the close of business on
the record date fixed for the determination of holders of Common Stock entitled to receive such
cash dividend or distribution
shall be reduced, effective as of the close of business on such record date, to a price determined
by multiplying such Exercise Price by a fraction of which:

-4-

 

          (i) the numerator shall be the Market Price of the Common Stock on the Trading Day
immediately preceding such record date minus the amount of the cash dividend or
distribution applicable to one share of Common Stock, and

          (ii) the denominator shall be the Market Price of the Common Stock on the Trading
Day immediately preceding such record date;

and (b) the number of Exercise Shares obtainable upon exercise of this Warrant shall be increased
to a number of shares equal to the number of shares of Common Stock obtainable immediately prior to
the close of business on the record date fixed for the determination of holders of Common Stock
entitled to receive such cash dividend or distribution multiplied by the reciprocal
of the fraction set forth in the immediately preceding clause (a) of this Section 5.2.

     5.3. Other Events. If any event occurs of the type contemplated by the provisions of
this Section 5 but not expressly provided for by such provisions (including, without limitation,
the granting of stock appreciation rights, phantom stock rights or other rights with equity
features, or any stock repurchase or buyback), then the Company’s Board of Directors, acting in
good faith and consistent with their fiduciary duties, shall make an appropriate adjustment in the
Exercise Price and the number of shares of Common Stock obtainable upon exercise of this Warrant so
as to protect the rights of the holders of the Warrant.

	6.	 	ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION,
MERGER, ETC.

     6.1. Certain Adjustments. In case at any time or from time to time, the
Company shall (i) effect a capital reorganization, reclassification or recapitalization, (ii)
consolidate with or merge into any other person, or (iii) transfer all or substantially all of its
properties or assets to any other person under any plan or arrangement contemplating the
dissolution of the Company, then in each such case, this Warrant shall thereafter be exercisable
for the same kind and amounts of securities (including shares of stock) or other assets, or both,
which were issuable or distributable to the holders of outstanding Common Stock upon such
reorganization, reclassification, recapitalization, consolidation, merger or transfer, in respect
of that number of shares of Common Stock for which this Warrant could have been exercised
immediately prior to such reorganization, reclassification, recapitalization, consolidation, merger
or transfer; and, in any such case, appropriate adjustments (as determined in good faith by the
Board of Directors of the Company) shall be made to assure that the provisions set forth herein
shall thereafter be applicable, as nearly as reasonably may be practicable, in relation to any
securities or other assets thereafter deliverable upon the exercise of this Warrant.

     6.2. Continuation of Terms. Upon any reorganization, consolidation,
merger or transfer (and any dissolution following any transfer) referred to in this Section 6, this
Warrant shall continue in full force and effect and the terms hereof shall be applicable to the
shares of stock and other securities and property receivable on the exercise of this Warrant after
the consummation of such reorganization, consolidation or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be binding upon the issuer
of any such stock or other securities, including, in the case of any such transfer, the person
acquiring all or substantially all of
the properties or assets of the Company, whether or not such person shall have expressly assumed
the terms of this Warrant as provided in Section 8 hereof.

	7.	 	ADJUSTMENTS FOR ISSUANCE OF COMMON STOCK
AND AMOUNT OF OUTSTANDING COMMON STOCK.

     7.1. General. If at any time there shall occur any stock split, stock dividend,
reverse stock split or other subdivision of the Company’s Common Stock (“Stock
Event”), then the number of shares of Common Stock to be received by the holder of this
Warrant shall be appropriately adjusted such that the proportion of the number of shares issuable
hereunder to the total number of shares of the Company (on a fully diluted basis) prior to such
Stock Event is equal to the proportion of the number of shares issuable hereunder after such Stock
Event to the total number of shares of the Company (on a fully-diluted basis) after such Stock
Event. The Exercise Price shall be proportionately decreased or increased upon the occurrence of
any Stock Event; provided that in no event will the Exercise Price be less than the par
value of the Common Stock.

     7.2. Other Securities. In case any Other Securities shall have been
issued, or shall then be subject to issue upon the conversion or exchange of any stock (or Other
Securities) of the Company (or any other issuer of Other Securities or any other entity referred to
in Section 6 hereof) or to subscription, purchase or other acquisition pursuant to any rights or
options granted by the Company (or such other issuer or entity), the holder hereof shall be
entitled to receive upon exercise hereof such amount of Other Securities (in lieu of or in addition
to Common Stock) as is determined in accordance with the terms hereof, treating all references to
Common Stock herein as references to Other Securities to the extent applicable, and the
computations, adjustments and readjustments provided for in this Section 7 with respect to the
number of shares of Common Stock issuable upon exercise of this Warrant shall be made as nearly as
possible in the manner so provided and applied to determine the amount of Other Securities from
time to time receivable on the exercise of the Warrant, so as to provide the holder of the Warrant
with the benefits intended by this Section 7 and the other provisions of this Warrant.

     7.3. Adjustments for Dilutive
and Other Events.

     (a) Issuance of Additional Shares of
Common Stock. If at any time on or after the Bridge
Date, the Company shall issue any Additional Shares of Common Stock (including Additional Shares of
Common Stock deemed to be issued pursuant to Section 7.3(b) below), at a price per share (the
“Offering Price”) which is lower than the Reference Price on the date of such
issuance, then the number of shares of Common Stock to be received by the holder of this Warrant
upon the exercise hereof shall be adjusted to that number determined by multiplying (a) the number
of shares of Common Stock purchasable hereunder immediately prior thereto by (b) a fraction (i) the
numerator of which shall be the sum of (A) the number of shares of Common Stock Deemed Outstanding
immediately prior to the issuance of such shares of Common Stock plus (B) the number of shares of
Common Stock issued in the subject transaction and (ii) the denominator of which shall be an amount
equal to the sum of (x) the number of shares of Common Stock Deemed Outstanding immediately prior
to the issuance of such shares of Common Stock plus (y) the quotient of (1) the Offering
Price multiplied by the number of shares of Common Stock so issued by the Company,
divided by (2) the Reference Price in effect immediately prior to the issuance of
such shares. The provisions of this Section 7.3 shall not apply to (i) any issuance of additional
Common Stock for which an adjustment is provided under Section 7.1 hereof, (ii) any issuance of
Additional Shares of Common Stock the proceeds of which are immediately used for the repayment of all obligations of the
Company under the Credit Agreement, and (iii) )(A) the issuance of Common Stock upon the exercise
of options outstanding on the date hereof and (B) the issuance of options after the date hereof for
the purchase of

-6-

 

up to 1,169,848 shares (subject to adjustments for stock splits, reverse stock
splits, combinations and similar events) of Common Stock, and the issuance of Common Stock upon the
exercise of such options, pursuant to the Company’s 2001 Long Term Stock Incentive Plan, the
Harvest Natural Resources 2004 Long Term Incentive Plan, the Harvest Natural Resources 2006 Long
Term Incentive Plan and the Harvest Natural Resources 2010 Long-Term Incentive Plan (collectively,
the “Excluded Options”). When any adjustment is required to be made to the number of
shares hereunder pursuant to this Section 7.3(a), the Exercise Price shall be reduced to a price
(calculated to the nearest cent) as is equal to the quotient obtained by dividing (x) the product
of the Exercise Price multiplied by the number of shares of Common Stock issuable upon
exercise of this Warrant, in each case as in effect immediately before such adjustment, by (y) the
number of shares of Common Stock issuable upon exercise of this Warrant immediately after giving
effect to such adjustment.

     (b) 
Issue of Options and Convertible Securities Deemed Issue of Additional Shares of
Common Stock. If the Company at any time or from time to time on or after the Bridge Date shall
issue any Options (other than Excluded Options) or Convertible Securities, then the maximum number
of shares of Common Stock (as set forth in the instrument relating thereto without regard to any
provision contained therein for a subsequent adjustment of such number) issuable upon the exercise
of such Options or, in the case of Convertible Securities and Options therefor, the conversion or
exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock
issued as of the time of such issue, or, in case a record date shall have been fixed for such
issuance, as of the close of business on such record date, provided that Additional Shares
of Common Stock shall not be deemed to have been issued unless the consideration per share
(determined pursuant to Section 7.3(c) below) of such Additional Shares of Common Stock would be
less than the Reference Price in effect on the date of and immediately prior to such issue, or such
record date, as the case may be, and provided further that in any such case in which Additional
Shares of Common Stock are deemed to be issued (i) no further adjustment in the number of shares of
Common Stock for which this Warrant is exerciseable shall be made upon the subsequent issue of
Convertible Securities or shares of Common Stock upon the exercise of such Options or conversion or
exchange of such Convertible Securities, and (ii) upon the expiration or termination of any
unexercised Option, the number of shares of Common Stock for which this Warrant is then
exerciseable shall be readjusted, and the Additional Shares of Common Stock deemed issued as the
result of the original issue of such Option shall not be deemed issued for the purpose of such
readjustment; provided, however, that with respect to any Options or Convertible
Securities issued by the Company for which there is a subsequent adjustment which increases the
number of shares of Common Stock issuable upon conversion or exercise of such Options or
Convertible Securities or an adjustment which decreases the exercise price or conversion price of
such Options or Convertible Securities, then an adjustment to the number of shares of Common Stock
for which this Warrant is exerciseable shall be made under this Section 7.3 upon any such
adjustment to such Options or Convertible Securities as if such Options or Convertible Securities
were deemed to have been cancelled and reissued.

     (c) 
Determination of Consideration. For purposes of this Section 7.3, the consideration
received by the Company for the issue of any Additional Shares of Common Stock shall be computed as
follows:

-7-

 

     (i) Cash and Property: Such consideration shall:

     (A) insofar as it consists of cash, be equal to the total cash received by
the Company, excluding amounts paid or payable for accrued interest or accrued
dividends;

     (B) insofar as it consists of property other than cash, be computed at the
Fair Market Value thereof at the time of such issue determined as provided below;
and

     (C) in the event Additional Shares of Common Stock are issued together with
other shares or securities or other assets of the Company for consideration which
covers both, be the proportion of such consideration so received that is allocated
to such Additional Shares of Common Stock, computed as provided in or pursuant to
clauses (A) and (B) above.

If the Company shall issue (or shall be deemed to issue) Additional Shares of
Common Stock for no consideration, such Additional Shares of Common Stock shall be
deemed to have been issued for consideration equal to $.01 per share.

     (ii) Options and Convertible Securities. The consideration per share received by
the Company for Additional Shares of Common Stock deemed to have been issued pursuant to
Section 7.3(b), relating to Options and Convertible Securities, shall be determined by
dividing

     (A) the total amount, if any, received or receivable by the Company as
consideration for the issue of such Options or Convertible Securities, plus
the minimum aggregate amount of additional consideration (as set forth in the
instruments relating thereto, without regard to any provision contained therein for
a subsequent adjustment of such consideration) payable to the Company upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities, or in the case of Options for Convertible Securities, the exercise of
such Options for Convertible Securities and the conversion or exchange of such
Convertible Securities, by

     (B) the maximum number of shares of Common Stock (as set forth in the
instruments relating thereto, without regard to any provision contained therein for
a subsequent adjustment of such number) issuable upon the exercise of such Options
or the conversion or exchange of such Convertible Securities.

8. NO DILUTION OR IMPAIRMENT. The Company will not, by
amendment of 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 the Warrant, but will
at all times in good faith assist in the
carrying out of all such terms and in taking all such action as may be necessary or appropriate in
order to protect the rights of the holder of the Warrant against dilution. Without limiting the
generality of the foregoing, the Company (i) will not increase the par value of any shares of stock
receivable on the exercise of the Warrant above the amount payable therefor on such exercise, (ii)
will take all such action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and non-assessable shares of stock on the exercise of the Warrant from
time to time outstanding, and (iii) subject to Section 14, will not transfer all or substantially
all of its

-8-

 

properties and assets to any other entity (corporate or otherwise), or consolidate with
or merge into any other entity or permit any such entity to consolidate with or merge with the
Company (if the Company is not the surviving entity), unless such other entity shall expressly
assume in writing and will be bound by all the terms of this Warrant and the Warrant Purchase
Agreement.

9. CERTIFICATE AS TO ADJUSTMENTS. In each case of any event
that may require any adjustment or readjustment in the shares of Common Stock issuable on the
exercise of this Warrant, the Company at its expense will promptly prepare a certificate setting
forth such adjustment or readjustment, or stating the reasons why no adjustment or readjustment is
being made, and showing, in detail, the facts upon which any such adjustment or readjustment is
based, including a statement of (i) the number of shares of Common Stock Deemed Outstanding, and
(ii) the number of shares of Common Stock to be received upon exercise of this Warrant, in effect
immediately prior to such adjustment or readjustment and as adjusted and readjusted (if required by
Section 7) on account thereof. The Company will forthwith mail a copy of each such certificate to
each holder of a Warrant, and will, on the written request at any time of any holder of a Warrant,
furnish to such holder a like certificate setting forth the calculations used to determine such
adjustment or readjustment.

10. NOTICES OF RECORD DATE. In the event of:

     (a) any taking by the Company of a record of the holders of any class of
securities for the purpose of determining the holders thereof who are entitled to receive
any dividend or other distribution, or any right to subscribe for, purchase or otherwise
acquire any shares of stock of any class or any other securities or property, or to receive
any other right; or

     (b) any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company or any transfer of all or
substantially all the assets of the Company to or any consolidation or merger of the
Company with or into any other Person or any other Fundamental Change; or

     (c) any voluntary or involuntary dissolution, liquidation or winding-up of the
Company,

     (d) any proposed issue or grant by the Company of any shares of stock of any class
or any other securities, or any right or option to subscribe for, purchase or otherwise
acquire any shares of stock of any class or any other securities (other than any issuance
or grant to which Section 7.3 hereof does not apply);

then, and in each such event, the Company will mail or cause to be mailed to the holder of this
Warrant a notice specifying (i) the date on which any such record is to be taken for the purpose of
such dividend, distribution or right, and stating the amount and character of such dividend,
distribution or right, (ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or winding-up is
anticipated to take place, and the time, if any is to be fixed, as of which the holders of record
of Common Stock (or Other Securities) shall be entitled to exchange their shares of Common Stock
(or Other Securities) for securities or other property deliverable on such reorganization,
reclassification, recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding-up and (iii) the amount and

-9-

 

character of any such stock or other such securities, or rights
or options with respect thereto, proposed to be issued or granted, the date of such proposed issue
or grant and the persons or class of persons to whom such proposed issue or grant is to be offered
or made. Such notice shall be mailed at least thirty (30) days prior to the date specified in such
notice on which any such action is to be taken.

11. RESERVATION OF STOCK ISSUABLE ON EXERCISE
OF WARRANT. The Company will at all times reserve and keep available, solely for
issuance and delivery on the exercise of this Warrant, a number of shares of Common Stock equal to
the total number of shares of Common Stock from time to time issuable upon exercise of this
Warrant, and, from time to time, will take all steps necessary to amend its Certificate of
Incorporation to provide sufficient reserves of shares of Common Stock issuable upon exercise of
this Warrant.

12. DEFINITIONS. As used herein the following terms, unless the context otherwise
requires, have the following respective meanings:

     
Additional Shares of Common Stock means all shares of Common Stock issued (or, pursuant to
Section 7.3(b) hereof, deemed to be issued) by the Company after the date hereof, including without
limitation any treasury shares sold or otherwise transferred by the Company, but excluding shares
of Common Stock issued or issuable by reason of a dividend, stock split, split-up or other
distribution on shares of Common Stock for which an adjustment is made pursuant to Section 7.1
hereof, but excluding shares of Common Stock issued or issuable upon exercise of any Excluded
Options.

     Appraisal Procedure means a procedure whereby two independent appraisers, one chosen
by the Company and one by the holder (or if there is more than one holder, a majority in interest
of holders), shall mutually agree upon the determinations then the subject of appraisal. Each
party shall deliver a notice to the other appointing its appraiser within 15 days after the
Appraisal Procedure is invoked. If within 30 days after appointment of the two appraisers they are
unable to agree upon the amount in question, a third independent appraiser shall be chosen within
10 days thereafter by the mutual consent of such first two appraisers or, if such first two
appraisers fail to agree upon the appointment of a third appraiser, such appointment shall be made
by the American Arbitration Association, or any organization successor thereto, from a panel of
arbitrators having experience in the appraisal of the subject matter to be appraised. The decision
of the third appraiser so appointed and chosen shall be given within 30 days after the selection of
such third appraiser. If three appraisers shall be appointed and the determination of one appraiser
is disparate from the middle determination by more than twice the amount by which the other
determination is disparate from the middle determination, then the determination of such appraiser
shall be excluded, the remaining two determinations shall be averaged and such average shall be
binding and conclusive on the Company and the holder; otherwise, the average of all three
determinations shall be binding and conclusive on
the Company and the holder. The costs of conducting any Appraisal Procedure shall be borne by the

actually outstanding at such time, plus the number of shares of Common Stock issuable at such time

over-the-counter trading facility on which the Common Stock is then principally traded or quoted at

-12-

 

     Trading Day means, at any time, a day on which the Principal Market is open for the
general trading or quotation of securities and the Common Stock is traded or quoted thereon without
suspension or interruption.

13. LIMITATION ON BENEFICIAL OWNERSHIP. Notwithstanding the foregoing, the holder
shall not be entitled to receive shares of Common Stock upon exercise of this Warrant to the extent
(but only to the extent) that such receipt would cause the holder to become, directly or
indirectly, a “beneficial owner” (within the meaning of Section 13(d) of the Exchange Act and the
rules and regulations promulgated thereunder) of a number of shares of Common Stock which exceeds
the Maximum Percentage of the shares of Common Stock outstanding at such time. This limitation on
beneficial ownership shall be terminated (i) upon 61 days’ notice to the Company by the holder or
(ii) immediately on the date that is 30 days prior to the expiration of the Exercise Period. Any
purported delivery of shares of Common Stock upon exercise of this Warrant shall be void and have
no effect to the extent (but only to the extent) that such delivery would result in the holder
becoming the beneficial owner of more than the Maximum Percentage of the shares of Common Stock
outstanding at such time. If any delivery of shares of Common Stock owed to the holder upon
exercise of this Warrant is not made, in whole or in part, as a result of this limitation, the
Company’s obligation to make such delivery shall not be extinguished and the Company shall deliver
such shares of Common Stock as promptly as practicable after the holder gives notice to the Company
that such delivery would not result in such limitation being triggered. For purposes of this
Section 13, (a) the term “Maximum Percentage” shall mean initially 5%; provided,
that if at any time after the date hereof the Holder Group beneficially owns in excess of 5% of the
outstanding shares of Common Stock (excluding any shares issuable under this Warrant and any other
convertible security including a similar limitation), then the Maximum Percentage shall
automatically increase to 10% so long as the Holder Group owns in excess of 5% of the outstanding
shares of Common Stock (excluding any shares issuable under this Warrant and any other convertible
security including a similar limitation), and (b) the term “Holder Group” shall mean the
holder of this Warrant plus any other person with which such holder is considered to be part of a
group under Section 13 of the Exchange Act or with which such holder otherwise files reports under
Sections 13 and/or 16 of the Exchange Act. The limitations in this Section 13 shall not have an
effect on any calculation or payment due to the Holder of this Warrant pursuant to Section 14
hereof.

14. FUNDAMENTAL CHANGE. Upon the occurrence of a Fundamental Change, the Company
shall, upon the consummation of such Fundamental Change, repurchase all of this Warrant at the
higher of (i) the Fair Market Value of the Warrant and (ii) a valuation based on a computation of
the option value of the Warrant using Black-Scholes calculation methods and making the assumptions
described in the Black-Scholes methodology described in Exhibit A. Payment of such
purchase price by the Company to the holder of this Warrant shall be due in cash upon the
occurrence of the Fundamental Change. The fact that this Warrant can only be exercised on a
cashless net exercise basis as provided in Section 2.2 shall not have any effect on any calculation or payment due to the
Holder of this Warrant pursuant to this Section 14. Any such calculation or payment shall assume
that this Warrant may be exercised either for cash or on a cashless basis, at the Holder’s
election. The Company agrees that it will not take any action resulting in a Preliminary
Fundamental Change or a Fundamental Change in the absence of definitive documentation providing for
such repurchase of the Warrant pursuant to this Section 14.

15. WARRANT AGENT. The Company may, by written notice to the holder of this
Warrant, appoint an agent for the purpose of issuing Common Stock on the exercise of this Warrant
pursuant to

-13-

 

Section 2 hereof, and exchanging or replacing this Warrant pursuant to the Warrant
Purchase Agreement, or any of the foregoing, and thereafter any such issuance, exchange or
replacement, as the case may be, shall be made at such office by such agent.

16. REMEDIES. The Company stipulates that the remedies at law of the holder of this
Warrant in the event of any default or threatened default by the Company in the performance of or
compliance with any of the terms of this Warrant are not and will not be adequate, and that such
terms may be specifically enforced by a decree for the specific performance of any agreement
contained herein or by an injunction against a violation of any of the terms hereof or otherwise.

17. NOTICES. All notices and other communications from the Company to the holder of
this Warrant shall be mailed by first class registered or certified mail, postage prepaid, or sent
by overnight courier (or sent in the form of a telex or telecopy) at such address as may have been
furnished to the Company in writing by such holder or, until any such holder furnishes to the
Company an address, then to, and at the address of, the last holder of this Warrant who has so
furnished an address to the Company.

18. MISCELLANEOUS. In case any provision of this Warrant shall be invalid, illegal or
unenforceable, or partially invalid, illegal or unenforceable, the provision shall be enforced to
the extent, if any, that it may legally be enforced and the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired thereby. This Warrant and
any term hereof may be changed, waived, discharged or terminated only by a statement in writing
signed by the party against which enforcement of such change, waiver, discharge or termination is
sought. This Warrant shall be governed by and construed in accordance with the domestic
substantive laws (and not the conflict of law rules) of the State of New York. The headings in
this Warrant are for purposes of reference only, and shall not limit or otherwise affect any of the
terms hereof. Notwithstanding anything contained herein to the contrary, any calculation or
analysis under this Warrant shall assume that this Warrant may be exercised either for cash or on a
cashless net exercise basis, at the Holder’s election, notwithstanding that this Warrant may only
be exercised on a cashless basis pursuant to the net exercise provisions set forth in Section 2.2.

shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the
Default Rate to the fullest extent permitted by applicable Laws.

     (ii) If any amount (other than principal of the Loan) payable by the Borrower under any
Loan Document is not paid when due (without regard to any applicable grace periods), whether
at stated maturity, by acceleration or otherwise, then such amount shall thereafter bear
interest at a rate per annum at all times equal to the Default Rate to the fullest extent
permitted by applicable Laws.

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

     (iv) Accrued and unpaid interest on past due amounts (including interest on past due
interest) shall be due and payable upon demand.

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

     2.05. Computation of Interest and Fees. All computations of fees, if any, and interest shall
be made on the basis of a 360-day year and actual days elapsed (which results in more fees or
interest, as applicable, being paid than if computed on the basis of a 365-day year). Interest
shall accrue on the Loan for the day on which the Loan is made, and shall not accrue on the Loan,
or any portion thereof, for the day on which the Loan or such portion is paid, provided
that any portion of the Loan that is repaid on the same day on which it is made shall, subject to
Section 2.07, bear interest for one day. Each determination by the Lender of an interest
rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error.

     2.06. Evidence of Debt. The Loan made by the Lender shall be evidenced by one or more
accounts or records maintained by the Lender. The accounts or records maintained by the Lender
shall be conclusive absent manifest error of the amount of the Loan made by the Lender to the
Borrower and the interest and payments thereon. Any failure to so record or any error in doing so
shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any
amount owing with respect to the Obligations.

     2.07. Payments Generally. All payments to be made by the Borrower shall be made without
condition or deduction for any counterclaim, defense, recoupment or setoff. Except as

-21-

 

otherwise expressly provided herein, all payments by the Borrower hereunder shall be made to
the Lender at the Lender’s office at 645 Fifth Avenue, 21st Floor, New York, New York 10022 (or
such other address as the Lender may from time to time notify the Borrower) in Dollars and in
immediately available funds not later than 2:00 p.m. on the date specified herein. All payments
received by the Lender after 2:00 p.m. shall be deemed received on the next succeeding Business Day
and any applicable interest or fee shall continue to accrue. If any payment to be made by the
Borrower shall come due on a day other than a Business Day, payment shall be made on the next
following Business Day, and such extension of time shall be reflected on computing interest or
fees, as the case may be.

ARTICLE III.

TAXES, YIELD PROTECTION AND ILLEGALITY

     3.01. Taxes. (a) Payments Free of Taxes; Obligation to Withhold; Payments on Account of
Taxes. Any and all payments by or on account of any obligation of the Loan Parties hereunder
or under any other Loan Document shall to the extent permitted by applicable Laws be made free and
clear of and without reduction or withholding for any Taxes. If, however, applicable Laws require
the Loan Parties to withhold or deduct any Tax, such Tax shall be withheld or deducted in
accordance with such Laws as determined by the Loan Parties upon the basis of the information and
documentation to be delivered pursuant to subsection (e) below. If the Loan Parties shall be
required by applicable Law to withhold or deduct any Taxes, including both United States Federal
backup withholding and withholding taxes, from any payment, then (A) the Loan Parties shall
withhold or make such deductions as are determined by the Loan Parties to be required based upon
the information and documentation it has received pursuant to subsection (e) below, (B) the Loan
Parties shall timely pay the full amount withheld or deducted to the relevant Governmental
Authority in accordance with applicable Laws, and (C) to the extent that the withholding or
deduction is made on account of Indemnified Taxes or Other Taxes, the sum payable by the Loan
Parties shall be increased as necessary so that after any required withholding or the making of all
required deductions (including deductions applicable to additional sums payable under this Section)
the Lender receives an amount equal to the sum it would have received had no such withholding or
deduction been made.

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

     (c) Tax Indemnifications. (i) Without limiting the provisions of subsection (a) or
(b) above, the Borrower shall, and does hereby, indemnify the Lender, and shall make payment in
respect thereof within 30 days after demand therefor, for the full amount of any Indemnified Taxes
or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable
to amounts payable under this Section) paid by the Lender, and any penalties, interest and
reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified
Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental
Authority. A certificate as to the amount of any such payment or liability delivered to the
Borrower by the Lender shall be conclusive absent manifest error.

-22-

 

     (ii) Without limiting the provisions of subsection (a) or (b) above, the Lender shall,
and does hereby, indemnify the Borrower, and shall make payment in respect thereof within 30
days after demand therefor, against any and all Taxes and any and all related losses,
claims, liabilities, penalties, interest and expenses (including the fees, charges and
disbursements of any counsel for the Borrower incurred by or asserted against the Borrower
by any Governmental Authority as a result of the failure by the Lender to deliver, or as a
result of the inaccuracy, inadequacy or deficiency of, any documentation required to be
delivered by the Lender to the Borrower pursuant to subsection (e). The agreements in this
clause (ii) shall survive the repayment, satisfaction or discharge of all of the
Obligations.

     (d) Evidence of Payments. As soon as reasonably practicable after the request by the
Borrower or the Lender, as the case may be, after any payment of Taxes by the Borrower or the
Lender to a Governmental Authority as provided in this Section 3.01, the Borrower shall
deliver to the Lender or the Lender shall deliver to the Borrower, as the case may be, the original
or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a
copy of any return required by Laws to report such payment or other evidence of such payment
reasonably satisfactory to the Borrower or the Lender, as the case may be.

     (e) Status of Lender; Tax Documentation. (i) If the Lender is entitled to an
exemption from or a reduction of withholding taxes with respect to payments hereunder or under any
other Loan Document, then the Lender shall deliver to the Borrower, on or prior to the date that
the Lender becomes a party to this Agreement (and from time to time thereafter at the time or times
prescribed by applicable Laws or when reasonably requested by the Borrower), such properly
completed and executed documentation prescribed by applicable Laws or by the taxing authorities of
any jurisdiction and such other reasonably requested information as will permit such payments made
to be made without withholding or at a reduced rate of withholding. Additionally, the Lender shall
deliver to the Borrower, on or prior to the date that the Lender becomes a party to this Agreement
(and from time to time thereafter at the time or times prescribed by applicable Law or when
reasonably requested by the Borrower), such properly completed and executed documentation
prescribed by applicable Law or by the taxing authorities of any jurisdiction and such other
reasonably requested information as will enable the Borrower (A) to determine whether or not
payments made hereunder or under any other Loan Document are subject to Taxes, (B) to determine, if
applicable, the required rate of withholding or deduction, and (C) otherwise to establish the
Lender’s status for withholding tax purposes in the applicable jurisdiction.

     (ii) Without limiting the generality of subsection (i), if the Borrower is resident for
tax purposes in the United States and the Lender is resident for tax purposes in the United
States, the Lender shall deliver to the Borrower, on or prior to the date that the Lender
becomes a party to this Agreement (and from time to time thereafter at the time or times
prescribed by applicable Law or when reasonably requested by the Borrower), properly
completed and executed originals of IRS Form W-9 (or successor form) or such other
documentation or information prescribed by applicable Laws or reasonably requested by the
Borrower as will certify that the Lender is not subject to United States Federal backup
withholding tax and as will enable the Borrower to determine whether or not the Lender is
subject to information reporting requirements.

-23-

 

     (iii) Without limiting the generality of subsection (i), if the Borrower is resident for
tax purposes in the United States, the Lender is not resident for tax purposes in the United
States and the Lender is entitled under the Code or any applicable treaty to an exemption
from or reduction of withholding tax with respect to payments hereunder or under any other
Loan Document, the Lender shall deliver to the Borrower on or prior to the date on which the
Lender becomes a party to this Agreement (and from time to time thereafter upon the request
of the Borrower, but only if the Lender is legally entitled to do so), whichever of the
following is applicable: (A) properly completed and executed originals of IRS W-8BEN (or
successor form) claiming eligibility for benefits of an income tax treaty to which the
United States is a party; (B) properly completed and executed originals of IRS Form W-8ECI
(or successor form); (C) in the case of the Lender claiming the benefits of the exemption
for portfolio interest under Section 881(c) of the Code, (1) a certificate in a form
approved by the Borrower to the effect that (i) the Lender is not a “bank” within the
meaning of Section 881(c)(3)(A) of the Code, (ii) the Lender is not a “10 percent
shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, (iii)
the Lender is not a “controlled foreign corporation” described in Section 881(c)(3)(C) of
the Code and (iv) no payments made hereunder or under any other Loan Document are
effectively connected with the Lender’s conduct of a United States trade or business and (2)
properly completed and executed originals of IRS Form W-8BEN or (or successor form); or (D)
any other form prescribed by applicable Law as a basis for claiming exemption from or
reduction in United States Federal withholding tax, properly completed and executed,
together with such other documentation as may be prescribed by applicable Law to permit the
Borrower to determine the withholding or deduction required to be made.

     (iv) Without limiting the generality of subsection (i), if the Lender would be subject
to United States Federal withholding taxes imposed by FATCA on payments made hereunder or
under any other Loan Document and the Lender fails to comply with the applicable reporting
requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code,
as applicable), the Lender shall provide such documentation prescribed by applicable law
(including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional
documentation reasonably requested by the Borrower as may be necessary for the Borrower to
comply with its obligations under FATCA, to determine that such Lender has complied with
such Lender’s obligations under FATCA, or to determine the amount to deduct and withhold
from any such payments.

     (v) The Lender shall promptly (A) notify the Borrower of any change in circumstances
which would modify or render invalid any claimed exemption or reduction in withholding taxes
with respect to payments made hereunder or under any other Loan Document, and (B) take such
steps as shall not be materially disadvantageous to it, in the reasonable judgment of the
Lender, and as may be reasonably necessary (including the designation of new Lending Office)
to avoid any requirement of applicable Laws of any jurisdiction that the Borrower make any
withholding or deduction for taxes from amounts payable to the Lender.

-24-

 

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

     3.02. Increased Costs. (a) Increased Costs Generally. If the Lender assigns, in
accordance with Section 9.07, all or any part of the Loan to a commercial bank or any other
entity that is subject to regulation by federal or state banking authorities (a “Bank Assignee”),
and if any Change in Law shall:

     (i) impose, modify or deem applicable any reserve, special deposit, compulsory loan,
insurance charge or similar requirement against assets of, deposits with or for the account
of, or credit extended or participated in by, the Bank Assignee;

     (ii) subject such Bank Assignee to any tax of any kind whatsoever with respect to this
Agreement, or change the basis of taxation of payments to such Bank Assignee in respect
thereof (except for Indemnified Taxes or Other Taxes covered by Section 3.01 and the
imposition of, or any change in the rate of, any Excluded Tax payable by or with respect to
such Bank Assignee); or

     (iii) impose on such Bank Assignee any other condition, cost or expense affecting this
Agreement;

and the result of any of the foregoing shall be to reduce the amount of any sum received or
receivable by such Bank Assignee hereunder (whether of principal, interest or any other amount)
then, upon request of such Bank Assignee, the Borrower will pay to such Bank Assignee such
additional amount or amounts as will compensate such Bank Assignee for such additional costs
incurred or reduction suffered.

     (b) Capital Requirements. If a Bank Assignee determines that any Change in Law
affecting such Bank Assignee or such Bank Assignee’s holding company, if any, regarding capital
requirements has or would have the effect of reducing the rate of return on such Bank Assignee’s
capital or on the capital of such Bank Assignee’s holding company, if any, as a consequence of this
Agreement or the portion of the Loan assigned to such Bank Assignee, to a level below that which
such Bank Assignee or such Bank Assignee’s holding company could have achieved but for such Change
in Law (taking into consideration such Bank Assignee’s policies and the policies of such Bank
Assignee’s holding company with respect to capital

-25-

 

adequacy), then from time to time the Borrower will pay to such Bank Assignee, such additional
amount or amounts as will compensate such Bank Assignee or such Bank Assignee’s holding company for
any such reduction suffered.

     (c) Certificates for Reimbursement. A certificate of a Bank Assignee setting forth
the amount or amounts necessary to compensate such Bank Assignee or its holding company, as
specified in subsection (a) or (b) of this Section and delivered to the Borrower shall be
conclusive absent manifest error. The Borrower shall pay such Bank Assignee the amount shown as
due on any such certificate within 10 days after receipt thereof.

     (d) Delay in Requests. Failure or delay on the part of a Bank Assignee to demand
compensation pursuant to the foregoing provisions of this Section shall not constitute a waiver of
such Bank Assignee’s right to demand such compensation, provided that the Borrower shall
not be required to compensate such Bank Assignee pursuant to the foregoing provisions of this
Section for any increased costs incurred or reductions suffered more than nine months prior to the
date that such Bank Assignee notifies the Borrower of the Change in Law giving rise to such
increased costs or reductions and of such Bank Assignee’s intention to claim compensation therefor
(except that, if the Change in Law giving rise to such increased costs or reductions is
retroactive, then the nine-month period referred to above shall be extended to include the period
of retroactive effect thereof).

     3.03. Survival. All of the Borrower’s obligations under this Article III shall
survive repayment of all other Obligations hereunder.

ARTICLE IV.

business a review of the effect of existing Environmental Laws on the Loan Parties’ and their
respective Subsidiaries’ business, operations and properties and claims asserted against the Loan
Parties and their respective Subsidiaries alleging potential liability or responsibility for
violation of any Environmental Law, and as a result thereof the Borrower has reasonably concluded

the Loan Parties, on any property formerly owned or operated by any Loan Party or any of its
Subsidiaries; other than in material compliance with applicable Environmental Laws, there is no

Environmental Law; and to the knowledge of the Loan Parties, all Hazardous Materials generated,
used, treated, handled or stored at, or transported to or from, any property currently or formerly
owned or operated by any Loan Party or any of its Subsidiaries have been disposed of in a manner
not reasonably expected to result in material liability to any Loan Party or any of its
Subsidiaries.

-30-

 

     5.10. Insurance. The properties of the Borrower and its Subsidiaries are insured with
financially sound and reputable insurance companies not Affiliates of the Borrower, in such
amounts, with such deductibles and covering such risks as are customarily carried by companies

have a Material Adverse Effect. Neither any Loan Party nor any Subsidiary thereof is party to any

combination agreement does not constitute a tax sharing agreement.

     8.03. Application of Funds. After the exercise of remedies provided for in Section

received on account of the Obligations shall be applied by the Lender in the following order:

     First, to payment of that portion of the Obligations constituting fees, indemnities,

     Third, to payment of that portion of the Obligations constituting unpaid principal of

-51-

 

     Last, the balance, if any, after all of the Obligations have been indefeasibly paid in

parties hereto.

     9.03. No Waiver; Cumulative Remedies; Enforcement. No failure by the Lender, to exercise,
and no delay by the Lender in exercising, any right, remedy, power or privilege hereunder or under
any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise

or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and
privileges herein provided, and provided under each other Loan Document, are cumulative and not
exclusive of any rights, remedies, powers and privileges provided by law.

     9.04. Expenses; Indemnity; Damage Waiver. (a) Expenses. The Borrower shall pay
(i) all reasonable out-of-pocket expenses incurred by the Lender and its Affiliates (including the
reasonable fees, charges and disbursements of counsel for the Lender), in connection with the

Loan Documents or any amendments, modifications or waivers of the provisions hereof or any
assignment, syndication, or grant of participation of the Lender’s rights and obligations hereunder
(whether or not the transactions contemplated hereby or thereby shall be consummated), and (ii) all
out-of-pocket expenses incurred by the Lender (including the reasonable fees, charges and
disbursements of any counsel for the Lender, in connection with the

-52-

 

enforcement or protection of
its rights (A) in connection with this Agreement and the other Loan
Documents, including its rights under this Section, or (B) in connection with Loan made
hereunder, including all such out-of-pocket expenses incurred during any workout, litigation,
restructuring or negotiations in respect of the Loan.

     (b) Indemnification by the Borrower. The Borrower shall indemnify the Lender and
each Related Party of any of the foregoing Persons (each such Person being called an
“Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims,
damages, liabilities and related expenses (including the fees, charges and disbursements of any
counsel for any Indemnitee), and shall indemnify and hold harmless each Indemnitee from all fees
and time charges and disbursements for attorneys who may be employees of any Indemnitee, incurred
by any Indemnitee or asserted against any Indemnitee by any third party or by the Borrower or any
other Loan Party arising out of, in connection with, or as a result of (i) the execution or
delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated
hereby or thereby, the performance by the parties hereto of their respective obligations hereunder
or thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) the Loan
or the use or proposed use of the proceeds therefrom, (iii) any actual or alleged presence or
Release of Hazardous Materials on or from any property owned or operated by the Borrower or any of

relating to any of the foregoing, whether based on contract, tort or any other theory, whether
brought by a third party or by the Borrower or any other Loan Party or any of the Borrower’s or
such Loan Party’s directors, shareholders or creditors, and regardless of whether any Indemnitee is
a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available
to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined
by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the
gross negligence or willful misconduct of such Indemnitee or (y) result from a claim brought by the
Borrower or any other Loan Party against an Indemnitee for breach in bad faith of such Indemnitee’s
obligations hereunder or under any other Loan Document, if the Borrower or such Loan Party has
obtained a final and nonappealable judgment in its favor on such claim as determined by a court of
competent jurisdiction.

     (c) Waiver of Consequential Damages, Etc. To the fullest extent permitted by
applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee,
on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to
direct or actual damages) arising out of, in connection with, or as a result of, this Agreement,
any other Loan Document or any agreement or instrument contemplated hereby, the transactions
contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof.
No Indemnitee referred to in subsection (b) above shall be liable for any damages arising from the
use by unintended recipients of any information or other materials distributed to such unintended
recipients by such Indemnitee through telecommunications, electronic or other information
transmission systems in connection with this Agreement or the other Loan Documents or the
transactions contemplated hereby or thereby other than for direct or actual damages resulting from
the gross negligence or willful misconduct of such Indemnitee as determined by a final and
nonappealable judgment of a court of competent jurisdiction.

-53-

 

     (d) Payments. All amounts due under this Section shall be payable not later than
ten Business Days after demand therefor.

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

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

     9.06. Tax Matters. The Borrower and the Lender agree and acknowledge that the Warrants
and the Note are being issued together as an “investment unit” within the meaning of Section
1273(c)(2) of the Code. For the purposes of allocating the issue price to the Warrants and the
Note as required by Section 1273(c)(2) of the Code and the Treasury regulations promulgated
thereunder, the Borrower and the Lender agree that the fair market value of the Warrants on the
date of issue is as set forth in the Warrant Purchase Agreement (the “Warrant Fair Market
Value”), and the fair market value of the Note on the date of issue is the result of
$60,000,000 minus the Warrant Fair Market Value. Except as otherwise required by applicable Law,
the Borrower and the Lender agree that they will use such allocation to prepare and file all tax
returns and other reports consistent with such allocation. The Borrower and the Lender acknowledge
that this Section 9.06 is intended to establish the allocation of the issue price of the
“investment unit” in accordance with Treasury regulations section 1.1273-2(h)(1) and Section
1273(c)(2) of the Code, which allocation is binding on the Borrower and the Lender pursuant to
Treasury regulations section 1.1273-2(h)(2).

     9.07. Successors and Assigns. The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and assigns permitted
hereby, except that the Borrower may not assign or otherwise transfer any of its rights or
obligations hereunder without the prior written consent of the Lender (and any other attempted
assignment or transfer by the Borrower shall be null and void). Prior to the occurrence of an
Event of Default, the Lender may assign, grant participations in or otherwise transfer any of its
rights or obligations hereunder and under the other Loan Documents (a) to an Affiliate, but only to
an Affiliate, of the Lender without the consent of the Borrower and (b) to a non-affiliate of the
Lender with the consent of the Borrower, which consent shall not be unreasonably withheld or
delayed. After the occurrence of an Event of Default, the Lender may assign, grant participations
in or otherwise transfer any of its rights or obligations hereunder and under the other Loan
Documents to one or more third parties without the consent of the Borrower. As a condition to any
permitted assignment by the Lender hereunder, the assignee shall be required to execute and deliver
to the Borrower a confidentiality agreement in form and substance reasonably acceptable to the
Borrower (it being agreed and understood that a confidentiality agreement in substantially the same
form as previously entered into by the Borrower with an

-54-

 

Affiliate of the Lender is acceptable to the Borrower). The Borrower agrees to promptly
execute and deliver to the Lender any and all amendments, agreements, notes and/or documents in
connection with any such permitted assignment, participation or other transfer as requested by the
Lender, including, without limitation, amended and restated loan documents to reflect a syndicated
credit facility. Any transferee or assignee permitted hereunder shall deliver to the Borrower the
documents and certifications required to be provided by a Lender under Section 3.01(e).
Notwithstanding anything herein to the contrary, no transferee or assignee shall be entitled to any
greater increased payments under Section 3.01 than that which the transferor Lender was
otherwise entitled.

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

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

     9.10. Counterparts; Integration; Effectiveness. This Agreement may be executed in
counterparts (and by different parties hereto in different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a single contract.
This Agreement and the other Loan Documents constitute the entire contract among the parties
relating to the subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Delivery of an executed
counterpart of a signature page of this Agreement by telecopy or other electronic imaging means
shall be effective as delivery of a manually executed counterpart of this Agreement.

-55-

 

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

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

     9.13. Governing Law; Jurisdiction; Etc. (a) GOVERNING LAW. THIS AGREEMENT SHALL
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

     (b) SUBMISSION TO JURISDICTION. THE BORROWER IRREVOCABLY AND UNCONDITIONALLY
SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE
OF NEW YORK OR ANY FEDERAL COURT SITTING IN THE BOROUGH OF MANHATTAN, THE CITY OF NEW YORK, AND ANY
APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH
OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH
ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE COURT OR, TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW, IN SUCH FEDERAL COURT. EACH OF THE PARTIES HERETO AGREES THAT
A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER
JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS
AGREEMENT OR IN ANY OTHER LOAN DOCUMENT SHALL AFFECT ANY RIGHT THAT THE LENDER MAY OTHERWISE HAVE
TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AGAINST THE
BORROWER OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION.

     (c) WAIVER OF VENUE. THE BORROWER IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE
LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT IN ANY

-56-

 

COURT REFERRED TO IN PARAGRAPH (B) OF THIS SECTION. EACH OF THE PARTIES HERETO HEREBY
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN
INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

     (d) SERVICE OF PROCESS. EACH PARTY HERETO IRREVOCABLY CONSENTS TO SERVICE OF
PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 9.02. NOTHING IN THIS AGREEMENT WILL
AFFECT THE RIGHT OF ANY PARTY HERETO TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE
LAW

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

     9.15. Electronic Execution of Assignments and Certain Other Documents. The words
“execution,” “signed,” “signature,” and words of like import in any amendment or other modification
hereof (including waivers and consents) shall be deemed to include electronic signatures or the
keeping of records in electronic form, each of which shall be of the same legal effect, validity or
enforceability as a manually executed signature or the use of a paper-based recordkeeping system,
as the case may be, to the extent and as provided for in any applicable law, including the Federal
Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures
and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

     9.16. USA PATRIOT Act. The Lender hereby notifies the Borrower that pursuant to the
requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26,
2001)) (the “Act”), may be required to obtain, verify and record information that identifies each
Loan Party, which information includes the name and address of each Loan Party and other
information that will allow the Lender to identify each Loan Party in accordance with the Act. The
Borrower shall, promptly following a request by the Lender, provide all documentation and other
information that the Lender requests in order to comply with its ongoing obligations under

FORM OF TERM NOTE

			
	$60,000,000
	 	October 28, 2010

     FOR VALUE RECEIVED, the undersigned HARVEST NATURAL RESOURCES, INC., a Delaware corporation
(the “Borrower”), hereby promises to pay to the order of MSD ENERGY INVESTMENTS PRIVATE II, LLC
(the “Lender”) at the Lender’s office at 645 Fifth Avenue, 21st Floor, New York, New York 10022:

     (a) prior to or on the Maturity Date the principal amount of Sixty Million and
00/100 Dollars ($60,000,000), evidencing the Loan made by the Lender to the Borrower
pursuant to the Credit Agreement dated of even date herewith (as amended and in effect from
time to time, the “Credit Agreement”), between the Borrower and the Lender;

     (b) the principal outstanding hereunder from time to time at the times provided in
the Credit Agreement; and

     (c) interest from the date hereof on the principal amount from time to time
outstanding to and including the maturity hereof at the rates and terms and in all cases in
accordance with the terms of the Credit Agreement.

     This Term Note evidences borrowings under and has been issued by the Borrower in accordance
with the terms of the Credit Agreement. The Lender and any holder hereof is entitled to the
benefits of the Credit Agreement and the other Loan Documents, and may enforce the agreements of
the Borrower contained therein, and any holder hereof may exercise the respective remedies provided
for thereby or otherwise available in respect thereof, all in accordance with the respective terms
thereof. All capitalized terms used in this Term Note and not otherwise defined herein shall have
the same meanings herein as in the Credit Agreement.

     The Borrower irrevocably authorizes the Lender to make or cause to be made, at the time of
receipt of any payment of principal of this Term Note, an appropriate notation on the grid attached
to this Term Note, or the continuation of such grid, or any other similar record, including
computer records, reflecting the receipt of such payment. The outstanding amount of the Loan set
forth on the grid attached to this Term Note, or the continuation of such grid, or any other
similar record, including computer records, maintained by the Lender with respect to the Loan shall
be, absent manifest error, prima facie evidence of the principal amount of the Loan
owing and unpaid to the Lender, but the failure to record, or any error in so recording, any such
amount on any such grid, continuation or other record shall not limit or otherwise affect the
obligation of the Borrower hereunder or under the Credit Agreement to make payments of principal of
and interest on this Term Note when due.

     The Borrower has the right in certain circumstances and the obligation under certain other
circumstances to prepay the whole or part of the principal of this Term Note on the terms and
conditions specified in the Credit Agreement.

Exhibit A - 1

 

     If any one or more of the Events of Default shall occur, the entire unpaid principal amount of
this Term Note and all of the unpaid interest accrued thereon may become or be declared due and
payable in the manner and with the effect provided in the Credit Agreement.

     No delay or omission on the part of the Lender or any holder hereof in exercising any right
hereunder shall operate as a waiver of such right or of any other rights of the Lender or such
holder, nor shall any delay, omission or waiver on any one occasion be deemed a bar or waiver of
the same or any other right on any future occasion.

     The Borrower and every endorser and guarantor of this Term Note or the obligation represented
hereby waives presentment, demand, notice, protest and all other demands and notices in connection
with the delivery, acceptance, performance, default or enforcement of this Term Note, and assents
to any extension or postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of collateral and to the addition or release of any other party
or person primarily or secondarily liable.

     THIS TERM NOTE AND THE OBLIGATIONS OF THE BORROWER HEREUNDER SHALL FOR ALL PURPOSES BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. THE BORROWER
AGREES THAT, AS MORE FULLY SET FORTH IN § 9.12(b) OF THE CREDIT AGREEMENT, ANY ACTION OR PROCEEDING
FOR THE ENFORCEMENT OF THIS TERM NOTE MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR ANY
FEDERAL COURT SITTING IN THE BOROUGH OF MANHATTAN, THE CITY OF NEW YORK, AND ANY APPELLATE COURT
FROM ANY THEREOF AND CONSENTS TO THE NONEXCLUSIVE JURISDICTION OF SUCH COURT AND THE SERVICE OF
PROCESS IN ANY SUCH SUIT BEING MADE UPON THE BORROWER BY MAIL AT THE ADDRESS SPECIFIED IN
SCHEDULE 9.02 OF THE CREDIT AGREEMENT. THE BORROWER HEREBY IRREVOCABLY AND UNCONDITIONALLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR
HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH ACTION OR PROCEEDING OR ANY SUCH COURT OR THAT
SUCH SUIT IS BROUGHT IN AN INCONVENIENT COURT AS MORE FULLY SET FORTH IN § 9.12(c) OF THE CREDIT
AGREEMENT.

     THE BORROWER HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY
RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF
OR RELATING TO THIS TERM NOTE OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR
THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). THE BORROWER (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT OR ATTORNEY OF THE LENDER OR ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR
OTHERWISE, THAT THE LENDER OR SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO
ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS TERM
NOTE AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE WAIVERS AND CERTIFICATIONS IN THIS
PARAGRAPH.

corporation (“Harvest Offshore”, and together with Harvest US Holdings and HNR UK, each
individually, a “Guarantor”, and collectively, the “Guarantors”), in favor of MSD
Energy Investments Private II, LLC, a Delaware limited liability company (the “Lender”).

     WHEREAS, Harvest Natural Resources, Inc., a Delaware corporation (the “Borrower”), has
entered into that certain Credit Agreement dated as of the date hereof (as amended and in effect
from time to time, the “Credit Agreement”), with the Lender, pursuant to which the Lender,
subject to the terms and conditions contained therein, is to provide the Borrower with the term
loan facility as provided for therein;

     WHEREAS, the Borrower and the Guarantors are members of a group of related entities, the
success of any one of which is dependent in part on the success of the other members of such group;

     WHEREAS, the Guarantors expect to receive substantial direct and indirect benefits from the
extensions of credit to the Borrower by the Lender pursuant to the Credit Agreement (which benefits
are hereby acknowledged);

     WHEREAS, it is a condition precedent to the Lender’s making any loan or otherwise extending
credit to the Borrower under the Credit Agreement that the Guarantors execute and deliver to the
Lender a guaranty substantially in the form hereof; and

     WHEREAS, the Guarantors wish to guaranty the Borrower’s obligations to the Lender under or in
respect of the Credit Agreement as provided herein.

     NOW, THEREFORE, each Guarantor hereby agrees with the Lender as follows:

     1. Definitions. The term “Obligations” and all other capitalized terms used
herein without definition shall have the respective meanings provided therefor in the Credit
Agreement.

     2. Guaranty of Payment and Performance. Each Guarantor hereby jointly and
severally guarantees to the Lender the full and punctual payment when due (whether at stated
maturity, by required pre-payment, by acceleration or otherwise), as well as the performance, of
all of the Obligations including all such Obligations which would become due but for the operation
of the automatic stay pursuant to §362(a) of the Federal Bankruptcy Code and the operation of
§§502(b) and 506(b) of the Federal Bankruptcy Code. This Guaranty is an absolute, unconditional
and continuing guaranty of the full and punctual payment and performance of all of the Obligations
and not of their collectibility only and is in no way conditioned upon any requirement that the
Lender first attempt to collect any of the Obligations from the Borrower or

Exhibit B - 1

 

any other guarantor or resort to any collateral security, guarantee of the Obligations or
other means of obtaining payment. Should the Borrower default in the payment or performance of any
of the Obligations, the obligations of each Guarantor hereunder with respect to such Obligations in
default shall become immediately due and payable to the Lender, without demand or notice of any
nature, all of which are expressly waived by each Guarantor. Payments by the Guarantors hereunder
may be required by the Lender on any number of occasions. All payments by the Guarantors hereunder
shall be made to the Lender, in the manner and at the place of payment specified therefor in the
Credit Agreement.

     3. Guarantors’ Agreement to Pay Enforcement Costs, etc. Each Guarantor further
agrees, as the principal obligor and not as a guarantor only, to pay to the Lender, on demand, all
costs and expenses (including court costs, legal expenses and costs and expenses incurred during
any workout, litigation, restructuring or negotiations in respect of the Obligations) incurred or
expended by the Lender and its Affiliates (including the reasonable fees, charges and disbursements
of counsel for the Lender) in connection with the Obligations, this Guaranty and the enforcement
thereof, together with interest on amounts recoverable under this §3 from the time when such
amounts become due until payment, whether before or after judgment, at the rate of interest for
overdue principal set forth in the Credit Agreement, provided that if such interest exceeds
the maximum amount permitted to be paid under applicable law, then such interest shall be reduced
to such maximum permitted amount.

     4. Waivers by Guarantor; Lender’s Freedom to Act. Each Guarantor agrees that the
Obligations will be paid and performed strictly in accordance with their respective terms,
regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting
any of such terms or the rights of the Lender with respect thereto. Each Guarantor waives
promptness, diligence, presentment, demand, protest, notice of acceptance, notice of any
Obligations incurred and all other notices of any kind, all defenses which may be available by
virtue of any valuation, stay, moratorium law or other similar law now or hereafter in effect, any
right to require the marshalling of assets of the Borrower or any other entity or other person
primarily or secondarily liable with respect to any of the Obligations, and all suretyship defenses
generally. Without limiting the generality of the foregoing, each Guarantor agrees to the
provisions of any instrument evidencing, securing or otherwise executed in connection with any
Obligation and agrees that the obligations of such Guarantor hereunder shall not be released or
discharged, in whole or in part, or otherwise affected by (i) the failure of the Lender to assert
any claim or demand or to enforce any right or remedy against the Borrower or any other entity or
other person primarily or secondarily liable with respect to any of the Obligations; (ii) any
extensions, compromise, refinancing, consolidation or renewals of any Obligation; (iii) any change
in the time, place or manner of payment of any of the Obligations or any rescissions, waivers,
compromise, refinancing, consolidation, amendments or modifications of any of the terms or
provisions of the Credit Agreement, the Notes, the other Loan Documents or any other agreement
evidencing, securing or otherwise executed in connection with any of the Obligations; (iv) the
addition, substitution or release of any entity or other person primarily or secondarily liable for
any Obligation, (v) the adequacy of any rights which the Lender may have against any collateral
security or other means of obtaining repayment of any of the Obligations; (vi) the impairment of
any collateral securing any of the Obligations, including without limitation the failure to perfect
or preserve any rights which the Lender might have in such collateral security or the substitution,
exchange, surrender, release, loss or destruction of any such collateral

Exhibit B - 2

 

security; or (vii) any other act or omission which might in any manner or to any extent vary
the risk of any Guarantor or otherwise operate as a release or discharge of such Guarantor, all of
which may be done without notice to the Guarantors. To the fullest extent permitted by law, each
Guarantor hereby expressly waives any and all rights or defenses arising by reason of (A) any “one
action” or “anti-deficiency” law which would otherwise prevent the Lender from bringing any action,
including any claim for a deficiency, or exercising any other right or remedy (including any right
of set-off), against such Guarantor before or after the Lender’s commencement or completion of any
foreclosure action, whether judicially, by exercise of power of sale or otherwise, or (B) any other
law which in any other way would otherwise require any election of remedies by the Lender. To the
extent that it lawfully may, each Guarantor hereby agrees that it will not invoke any law (other
than the applicable statute of limitations) which might cause delay in or impede the enforcement of
the rights and remedies of the Lender under this Guaranty, and to the fullest extent it lawfully
may, such Guarantor hereby irrevocably waives the benefits of all such laws. In addition, and
notwithstanding anything to the contrary contained herein, the Lender shall have the right, at any
time, to name any Guarantor as a party defendant in any foreclosure action(s) it or its assignee
may commence to foreclose upon any and all collateral of the Borrower or any other guarantor which
secures the Obligations.

     5. Unenforceability of Obligations Against Borrower or Other Guarantors. If for
any reason the Borrower or any other guarantor has no legal existence or is under no legal
obligation to discharge any of the Obligations, or if any of the Obligations have become
irrecoverable from the Borrower or any other guarantor by reason of the Borrower’s or such other
guarantor’s insolvency, bankruptcy or reorganization or by other operation of law or for any other
reason, this Guaranty shall nevertheless be binding on each Guarantor, to the same extent as if
such Guarantor at all times had been the principal obligor on all such Obligations. In the event
that acceleration of the time for payment of any of the Obligations is stayed upon the insolvency,
bankruptcy or reorganization of the Borrower, or for any other reason, all such amounts otherwise
subject to acceleration under the terms of the Credit Agreement, the Notes, the other Loan
Documents or any other agreement evidencing, securing or otherwise executed in connection with any
Obligation shall be immediately due and payable by the Guarantor.

     6. Subrogation; Subordination.

     6.1. Waiver of Rights Against Borrower. Until the final payment and
performance in full of all of the Obligations and any and all other obligations of the
Borrower to the Lender or any affiliate of the Lender, no Guarantor shall exercise any
rights against the Borrower or any other guarantor of the Obligations arising as a result of
payment by any Guarantor hereunder (or any other guarantor), by way of subrogation,
reimbursement, restitution, contribution or otherwise, and no Guarantor will prove any claim
in competition with the Lender or such affiliate in respect of any payment hereunder in any
bankruptcy, insolvency or reorganization case or proceedings of any nature; no Guarantor
will claim any setoff, recoupment or counterclaim against the Borrower in respect of any
liability of any Guarantor to the Borrower; and each Guarantor waives any benefit of and any
right to participate in any collateral security which may be held by the Lender or such
affiliate.

Exhibit B - 3

 

     6.2. Subordination to Lender. The payment of any amounts due with respect
to any indebtedness of the Borrower or any other guarantor of the Obligations now or
hereafter owed to the Guarantor is hereby subordinated to the prior payment in full of all
of the Obligations and any and all other obligations of the Borrower or any other guarantor
of the Obligations to the Lender or any affiliate of the Lender. Each Guarantor agrees
that, after the occurrence of any default in the payment or performance of any of the
Obligations, such Guarantor will not demand, sue for or otherwise attempt to collect any
such indebtedness of the Borrower or any other guarantor of the Obligations to such
Guarantor until all of the Obligations shall have been paid in full. If, notwithstanding
the foregoing sentence, the Guarantor shall collect, enforce or receive any amounts in
respect of such indebtedness, such amounts shall be collected, enforced and received by such
Guarantor as trustee for the Lender and be paid over to the Lender on account of the
Obligations without affecting in any manner the liability of such Guarantor under the other
provisions of this Guaranty.

     6.3. Subordination of Obligations. Each Guarantor covenants and agrees,
and the Lender, by its acceptance of this Guaranty likewise covenants and agrees, that
payment of the Obligations by any of the Guarantors arising under this Guaranty shall be
subordinated to the Indebtedness of Subsidiaries permitted under Section 7.02(j) and
Section 7.02(n) of the Credit Agreement, such subordination arrangements to be on
terms and conditions reasonably satisfactory to the Lender.

     6.4. Provisions Supplemental. The provisions of this §6 shall be
supplemental to and not in derogation of any rights and remedies of the Lender or any
affiliate of the Lender under any separate subordination agreement which the Lender or such
affiliate may at any time and from time to time enter into with any Guarantor.

     7. Security; Setoff. Each Guarantor grants to the Lender, as security for the
full and punctual payment and performance of all of such Guarantor’s obligations hereunder, a
continuing lien on and security interest in all securities or other property belonging to such
Guarantor now or hereafter held by the Lender and in all deposits (general or special, time or
demand, provisional or final) and other sums credited by or due from the Lender to such Guarantor
or subject to withdrawal by such Guarantor. Regardless of the adequacy of any collateral security
or other means of obtaining payment of any of the Obligations, the Lender is hereby authorized at
any time and from time to time, without notice to such Guarantor (any such notice being expressly
waived by such Guarantor) and to the fullest extent permitted by law, to set off and apply such
deposits and other sums against the obligations of such Guarantor under this Guaranty, whether or
not the Lender shall have made any demand under this Guaranty and although such obligations may be
contingent or unmatured.

     8. Further Assurances. Each Guarantor agrees that it will from time to time, at
the request of the Lender, provide to the Lender such Guarantor’s most recent audited and unaudited
balance sheets and related statements of income and changes in financial condition and such other
information relating to the business and affairs of such Guarantor as the Lender may reasonably
request. Each Guarantor also agrees to do all such things and execute all such documents as the
Lender may consider necessary or desirable to give full effect to this Guaranty and to perfect and
preserve the rights and powers of the Lender hereunder. Each Guarantor

Exhibit B - 4

 

acknowledges and confirms that such Guarantor itself has established its own adequate means of
obtaining from the Borrower on a continuing basis all information desired by such Guarantor
concerning the financial condition of the Borrower and that such Guarantor will look to the
Borrower and not to the Lender in order for such Guarantor to keep adequately informed of changes
in the Borrower’s financial condition.

     9. Termination; Reinstatement. Upon final payment and performance in full in cash
of the Obligations (other than inchoate indemnification liabilities arising under the Loan
Documents) and termination of all lending and other credit commitments of the Lender and its
affiliates in respect thereof, this Guaranty shall terminate. Such termination shall not affect
any rights of the Lender or of any affiliate of the Lender hereunder (including without limitation
the rights set forth in §§4 and 6) with respect to any Obligations incurred or accrued prior to the
receipt of such notice or any Obligations incurred or accrued pursuant to any contract or
commitment in existence prior to such receipt. Notwithstanding the foregoing, this Guaranty shall
continue to be effective or be reinstated if at any time any payment made or value received with
respect to any Obligation is rescinded or must otherwise be returned by the Lender upon the
insolvency, bankruptcy or reorganization of the Borrower, or otherwise, all as though such payment
had not been made or value received.

     10. Successors and Assigns. This Guaranty shall be binding upon each Guarantor,
its successors and assigns, and shall inure to the benefit of and be enforceable by the Lender and
its successors, transferees and assigns. Without limiting the generality of the foregoing
sentence, the Lender may assign or otherwise transfer the Credit Agreement, the Notes, the other
Loan Documents or any other agreement or note held by it evidencing, securing or otherwise executed
in connection with the Obligations, or sell participations in any interest therein, to any other
entity or other person, and such other entity or other person shall thereupon become vested, to the
extent set forth in the agreement evidencing such assignment, transfer or participation, with all
the rights in respect thereof granted to the Lender herein. No Guarantor may assign its rights
hereunder.

     11. Amendments and Waivers. No amendment or waiver of any provision of this
Guaranty nor consent to any departure by any Guarantor therefrom shall be effective unless the same
shall be in writing and signed by the Lender. No failure on the part of the Lender to exercise, and
no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single
or partial exercise of any right hereunder preclude any other or further exercise thereof or the
exercise of any other right.

     12. Notices.

     12.1. Notices Generally. All notices and other communications provided for
herein shall be in writing and shall be delivered by hand or overnight courier service,
mailed by certified or registered mail or sent by telecopier as follows: if to any
Guarantor, at the address or telecopier number set forth beneath its signature hereto, and
if to the Lender, at the address for notices to the Lender set forth in Schedule
9.02 of the Credit Agreement.

Exhibit B - 5

 

     Notices and other communications sent by hand or overnight courier service, or mailed
by certified or registered mail, shall be deemed to have been given when received; notices
and other communications sent by telecopier shall be deemed to have been given when sent
(except that, if not given during normal business hours for the recipient, shall be deemed
to have been given at the opening of business on the next business day for the recipient).

     12.2. Change of Address. Each Guarantor and the Lender may change its
address or telecopier number for notices and other communications hereunder by notice to the
other parties hereto.

     12.3. Reliance by Lender. The Lender shall be entitled to rely and act
upon any notices purportedly given by or on behalf of any Guarantor even if (i) such notices
were not made in a manner specified herein, were incomplete or were not preceded or followed
by any other form of notice specified herein, or (ii) the terms thereof, as understood by
the recipient, varied from any confirmation thereof. Each Guarantor shall indemnify the
Lender and the Related Parties (as defined in the Credit Agreement) of each of them from all
losses, costs, expenses and liabilities resulting from the reliance by such Person on each
notice purportedly given by or on behalf of such Guarantor.

     13. Governing Law. THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

     14. Submission to Jurisdiction. EACH GUARANTOR IRREVOCABLY AND UNCONDITIONALLY
SUBMITS, FOR ITSELF AND ITS PROPERTY, TO THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE
OF NEW YORK OR ANY FEDERAL COURT SITTING IN THE BOROUGH OF MANHATTAN, THE CITY OF NEW YORK, AND ANY
APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
GUARANTY OR ANY OTHER LOAN DOCUMENT, OR FOR RECOGNITION OR ENFORCEMENT OF ANY JUDGMENT, AND EACH
GUARANTOR IRREVOCABLY AND UNCONDITIONALLY AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION OR
PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE COURT OR, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, IN SUCH FEDERAL COURT. EACH GUARANTOR AGREES THAT A FINAL JUDGMENT IN
ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY
SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS GUARANTY OR IN ANY
OTHER LOAN DOCUMENT SHALL AFFECT ANY RIGHT THAT THE LENDER MAY OTHERWISE HAVE TO BRING ANY ACTION
OR PROCEEDING RELATING TO THIS GUARANTY OR ANY OTHER LOAN DOCUMENT AGAINST ANY GUARANTOR OR ANY
OTHER LOAN PARTY (AS DEFINED IN THE CREDIT AGREEMENT) OR ITS PROPERTIES IN THE COURTS OF ANY
JURISDICTION.

     15. Waiver of Venue. EACH GUARANTOR IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO

Exhibit B - 6

 

THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTY OR
ANY OTHER LOAN DOCUMENT IN ANY COURT REFERRED TO IN §14. EACH GUARANTOR HEREBY IRREVOCABLY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT FORUM TO THE
MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

     16. Service of Process. EACH GUARANTOR IRREVOCABLY CONSENTS TO SERVICE OF PROCESS
IN THE MANNER PROVIDED FOR NOTICES IN §12. NOTHING IN THIS GUARANTY WILL AFFECT THE RIGHT OF THE
LENDER OR ANY GUARANTOR TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.

     17. Waiver of Jury Trial. EACH GUARANTOR HEREBY IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL
PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS GUARANTY OR ANY OTHER LOAN
DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY
OTHER THEORY). EXCEPT AS PROHIBITED BY LAW, EACH GUARANTOR HEREBY WAIVES ANY RIGHT WHICH IT MAY
HAVE TO CLAIM OR RECOVER IN ANY LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL
DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES. EACH GUARANTOR (I) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE LENDER OR ANY OTHER PERSON HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT THE LENDER OR SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION,
SEEK TO ENFORCE THE FOREGOING WAIVER AND (II) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO
HAVE BEEN INDUCED TO ENTER INTO THIS GUARANTY AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS,
THE WAIVERS AND CERTIFICATIONS IN THIS §17.

     18. Joint and Several Nature of Guaranty. Notwithstanding any term contained
herein to the contrary, each of the obligations and liabilities of each of the Guarantors hereunder
are expressly agreed to be joint and several.

     19. Contribution. To the extent any Guarantor makes a payment hereunder in excess
of the aggregate amount of the benefit received by such Guarantor in respect of the extensions of
credit under the Credit Agreement (the “Benefit Amount”), then such Guarantor, after the payment in
full, in cash, of all of the Obligations, shall be entitled to recover from each other guarantor of
the Obligations such excess payment, pro rata, in accordance with the ratio of the Benefit Amount
received by each such other guarantor to the total Benefit Amount received by all guarantors of the
Obligations, and the right to such recovery shall be deemed to be an asset and property of such
Guarantor so funding; provided, that all such rights to recovery shall be subordinated and junior
in right of payment to the final and undefeasible payment in full in cash of all of the
Obligations.

Exhibit B - 7

 

     20. Miscellaneous. This Guaranty constitutes the entire agreement of each
Guarantor with respect to the matters set forth herein. The rights and remedies herein provided
are cumulative and not exclusive of any remedies provided by law or any other agreement, and this
Guaranty shall be in addition to any other guaranty of or collateral security for any of the
Obligations. The invalidity or unenforceability of any one or more sections of this Guaranty shall
not affect the validity or enforceability of its remaining provisions. Captions are for the ease
of reference only and shall not affect the meaning of the relevant provisions. The meanings of all
defined terms used in this Guaranty shall be equally applicable to the singular and plural forms of
the terms defined.
