FOOTHILLS RESOURCES, INC.

WARRANT TO PURCHASE COMMON STOCK

Foothills Resources, Inc., a Nevada corporation (the “Company”), for value received on
December 13,   2007 (the “Effective Date”), hereby issues to Regiment Capital Special
Situations Fund III, L.P. (such person and any successors and/or assigns each being the
“Holder” with respect to the Warrant held by it) this Warrant (the “Warrant”) to
purchase 2,580,159 shares (each such share as from time to time adjusted as hereinafter provided
being a “Warrant Share” and all such shares being the “Warrant Shares”) of the
Company’s Common Stock, at the Exercise Price, as adjusted from time to time as provided herein, on
or before December 13, 2017 (the “Expiration Date”), all subject to the following terms and
conditions.

Certain terms used herein shall have the meanings set forth on Exhibit C hereto. Unless
otherwise defined in this Warrant (including Exhibit C), terms appearing in initial
capitalized form shall have the meaning ascribed to them in that certain Credit Agreement, dated as
of even date herewith, by and among the Company, certain subsidiaries of the Company and the other
parties signatory thereto pursuant to which this Warrant was issued (the “Credit
Agreement”).

1. DURATION AND EXERCISE OF WARRANTS

     (a) Exercise Period. The Holder may exercise this Warrant in whole or in part on any
Business Day on or before 5:00 p.m., Eastern time, on the Expiration Date, at which time this
Warrant shall become void and of no value.

     (b) Exercise Procedures.

          (i) While this Warrant remains outstanding and exercisable in accordance with Section
1(a), the Holder may exercise this Warrant in whole or in part at any time and from time to
time by (A) surrender of this Warrant, with a duly executed copy of the Notice of Exercise attached
hereto as Exhibit A, to the Secretary of the Company at its principal offices or at such
other office or agency as the Company may specify in writing to the Holder, and payment of the then
applicable Exercise Amount

 

 

made in the form of cash, or by certified check, bank draft or money order payable in lawful
money of the United States of America, (B) by exchanging a portion of this Warrant pursuant to
which the Holder receives from the Company the number of Warrant Shares equal to (A) the number of
Warrant Shares as to which this Warrant is being exercised minus (B) the number of Warrant
Shares having a value, based on the Closing Price on the trading day immediately prior to the date
of such exercise, equal to the Exercise Amount, or (C) any combination of the foregoing. The
Company acknowledges that the provisions of clause (B) are intended, in part, to ensure that a full
or partial exchange of this Warrant pursuant to such clause (ii) will qualify as a conversion,
within the meaning of paragraph (d)(3)(iii) of Rule 144 under the Securities Act. At the request
of any Holder, the Company will accept reasonable modifications to the exchange procedures provided
for in this Section in order to accomplish such intent. For all purposes of this Warrant (other
than this section), any reference herein to the exercise of this Warrant shall be deemed to include
a reference to the exchange of this Warrant into Shares in accordance with the terms of clause (B).

          (ii) Upon the exercise of this Warrant in compliance with the provisions of this
Section 1(b), the Company shall promptly issue and cause to be delivered to the Holder a
certificate for the Warrant Shares purchased by the Holder. Each exercise of this Warrant shall be
effected immediately prior to the close of business on the date (the “Date of Exercise”)
which the conditions set forth in Section 1(b) have been satisfied. On or before the first
(1st) Business Day following the date on which the Company has received each of the
Exercise Notice and the Exercise Amount (the “Exercise Delivery Documents”), the Company
shall transmit by facsimile an acknowledgment of confirmation of receipt of the Exercise Delivery
Documents to the Holder and the Company’s transfer agent (the “Transfer Agent”). On or
before the third (3rd) Business Day following the date on which the Company has received
all of the Exercise Delivery Documents (the “Share Delivery Date”), the Company shall, (X)
provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”)
Fast Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate
number of shares of Common Stock to which the Holder is entitled pursuant to such exercise to the
Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission
system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities
Transfer Program, issue and dispatch by overnight courier to the address as specified in the
Exercise Notice, a certificate, registered in the Company’s share register in the name of the
Holder or its designee, for the number of shares of Common Stock to which the Holder is entitled
pursuant to such exercise. Upon delivery of the Exercise Notice and Exercise Amount, the Holder
shall be deemed for all corporate purposes to have become the holder of record of the Warrant
Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery
of the certificates evidencing such Warrant Shares. If this Warrant is submitted in connection
with any exercise pursuant to Section 1(a) and the number of Warrant Shares represented by
this Warrant submitted for exercise is greater than the actual number of Warrant Shares being
acquired upon such an exercise, then the Company shall as soon as practicable and in no event later
than three (3) Business Days after any exercise and at its own expense, issue a new Warrant (in
accordance with Section 1(b)) of like tenor representing the right to purchase the number
of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the
number of Warrant Shares with respect to which this Warrant is exercised. No fractional shares of
Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of
Common Stock to be issued shall be rounded up to the nearest whole number. The Company shall pay
any and all stamp or other documentary taxes which may be payable with respect to the issuance and
delivery of Warrant Shares upon exercise of this Warrant.

          (iii) If the Company shall fail to issue to the Holder within three (3) Business Days of
receipt of the Exercise Delivery Documents, a certificate for the number of shares of Common Stock
to which the Holder is entitled and register such shares of Common Stock on the Company’s share
register or to credit the Holder’s balance account with DTC for such number of shares of Common
Stock to which

2

 

the Holder is entitled upon the Holder’s exercise of this Warrant, and if on or after such
Business Day the Holder purchases (in an open market transaction or otherwise) shares of Common
Stock to deliver in satisfaction of a sale by the Holder of shares of Common Stock issuable upon
such exercise that the Holder anticipated receiving from the Company (a “Buy-In”), then the
Company shall, within three (3) Business Days after the Holder’s request and in the Holder’s
discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase
price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the
“Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and
to issue such shares of Common Stock) shall terminate, or (ii) promptly honor its obligation to
deliver to the Holder a certificate or certificates representing such shares of Common Stock and
pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the
product of (A) such number of shares of Common Stock, times (B) the closing bid price on the date
of exercise.

     (c) Partial Exercise. This Warrant shall be exercisable, either as an entirety or,
from time to time, for part only of the number of Warrant Shares referenced by this Warrant. If
this Warrant is exercised in part, the Company shall issue, at its expense, a new Warrant, in
substantially the form of this Warrant, referencing such reduced number of Warrant Shares which
remain subject to this Warrant.

     (d) Disputes. In the case of a dispute as to the determination of the Exercise Price
or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder
the number of Warrant Shares that are not disputed and resolve such dispute in accordance with
Section 15.

2. ISSUANCE OF WARRANT SHARES; CERTAIN COVENANTS OF THE COMPANY

     (a) The Company represents and warrants that the Warrants and this Warrant Certificate have
been duly authorized and issued by the Company and represent a valid and binding obligation on the
Company, enforceable against the Company in accordance with its terms. The Company covenants that
all Warrant Shares will, upon issuance in accordance with the terms of this Warrant, be (i) duly
authorized, validly issued, fully paid and non-assessable, and (ii) free from all liens, charges
and security interests, with the exception of claims arising through the acts or omissions of any
Holder and except as arising from applicable Federal and state securities laws.

     (b) The Company shall register this Warrant upon records to be maintained by the Company for
that purpose in the name of the record holder of such Warrant from time to time. The Company may
deem and treat the registered Holder of this Warrant as the absolute owner thereof for the purpose
of any exercise thereof, any distribution to the Holder thereof and for all other purposes.

     (c) The Company will not, by amendment of its certificate of incorporation, by-laws 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 to be observed or performed hereunder by the Company, but will at all times in
good faith assist in the carrying out of all the provisions of this Warrant and in the taking of
all the action as may be necessary or appropriate in order to protect the rights of the Holder to
exercise this Warrant , or against impairment of such rights .

3. ADJUSTMENTS OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES

     (a) The Exercise Price and the number of shares purchasable upon the exercise of this Warrant
shall be subject to adjustment from time to time upon the occurrence of certain events described in
this Section 3(a).

3

 

          (i) Subdivision or Combination of Stock. In case the Company shall at any time
subdivide (whether by way of stock dividend, stock split or otherwise) its outstanding shares of
Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to
such subdivision shall be proportionately reduced and the number of Warrant Shares shall be
proportionately increased , and conversely, in case the outstanding shares of Common Stock of the
Company shall be combined (whether by way of stock combination, reverse stock split or otherwise)
into a smaller number of shares, the Exercise Price in effect immediately prior to such combination
shall be proportionately increased and the number of Warrant Shares shall be proportionately
decreased. The Exercise Price and the Warrant Shares, as so adjusted, shall be readjusted in the
same manner upon the happening of any successive even or events described in this Section
3(a)(i).

          (ii) Dividends in Stock, Property, Reclassification. If at any time, or from time to
time, the holders of Common Stock (or any shares of stock or other securities at the time
receivable upon the exercise of this Warrant) shall have received or become entitled to receive,
without payment therefor:

     (A) any shares of stock or other securities which are at any time directly or
indirectly convertible into or exchangeable for Common Stock, or any rights or
options to subscribe for, purchase or otherwise acquire any of the foregoing by way
of dividend or other distribution, or

     (B) additional stock or other securities or property (including cash) by way of
spin-off, split-up, reclassification, combination of shares or similar corporate
rearrangement, (other than shares of Common Stock issued as a stock split or
adjustments in respect of which shall be covered by the terms of Section
3(a)(i) above), then and in each such case, the Exercise Price and the number of
Warrant Shares to be obtained upon exercise of this Warrant shall be adjusted
proportionately, and the Holder hereof shall, upon the exercise of this Warrant, be
entitled to receive, in addition to the number of shares of Common Stock receivable
thereupon, and without payment of any additional consideration therefor, the amount
of stock and other securities and property (including cash in the cases referred to
in clause (ii) above) which such Holder would hold on the date of such exercise had
he been the holder of record of such Common Stock as of the date on which holders of
Common Stock received or became entitled to receive such shares or all other
additional stock and other securities and property. The Exercise Price and the
Warrant Shares, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described in this Section
3(a)(ii).

          (iii) Reorganization, Reclassification, Consolidation, Merger or Sale. If any
recapitalization, reclassification or reorganization of the capital stock of the Company, or any
consolidation or merger of the Company with another corporation, or the sale of all or
substantially all of its assets or other transaction shall be effected in such a way that holders
of Common Stock shall be entitled to receive stock, securities, or other assets or property (an
“Organic Change”), then, as a condition of such Organic Change, lawful and adequate provisions
shall be made by the Company whereby the Holder hereof shall thereafter have the right to purchase
and receive (in lieu of the shares of the Common Stock of the Company immediately theretofore
purchasable and receivable upon the exercise of the rights represented by this Warrant) such shares
of stock, securities or other assets or property as may be issued or payable with respect to or in
exchange for a number of outstanding shares of such Common Stock equal to the number of shares of
such stock immediately theretofore purchasable and receivable assuming the full exercise of the
rights represented by this Warrant. In the event of any Organic Change, appropriate provision shall
be made by the Company with respect to the rights and interests of the Holder of this Warrant to
the end that the provisions hereof (including, without limitation, provisions for adjustments of
the Exercise Price and of the number of shares purchasable and receivable upon the

4

 

exercise of this Warrant) shall thereafter be applicable, in relation to any shares of stock,
securities or assets thereafter deliverable upon the exercise hereof. The Company will not effect
any such consolidation, merger or sale unless, prior to the consummation thereof, the successor
corporation (if other than the Company) resulting from such consolidation or merger or the
corporation purchasing such assets shall assume by written instrument reasonably satisfactory in
form and substance to the Holders executed and mailed or delivered to the registered Holder hereof
at the last address of such Holder appearing on the books of the Company, the obligation to deliver
to such Holder such shares of stock, securities or assets as, in accordance with the foregoing
provisions, such Holder may be entitled to purchase. In any event, the successor corporation (if
other than the Company) resulting from such consolidation or merger or the corporation purchasing
such assets shall be deemed to assume such obligation to deliver to such Holder such shares of
stock, securities or assets even in the absence of a written instrument assuming such obligation to
the extent such assumption occurs by operation of law.

     (b) Certificate as to Adjustments. Upon the occurrence of each adjustment or
readjustment pursuant to this Section 3, the Company at its expense shall promptly compute such
adjustment or readjustment in accordance with the terms hereof and furnish to each Holder of this
Warrant a certificate setting forth such adjustment or readjustment and showing in detail the facts
upon which such adjustment or readjustment is based. The Company shall promptly furnish or cause to
be furnished to such Holder a like certificate setting forth: (i) such adjustments and
readjustments; and (ii) the number of shares and the amount, if any, of other property which at the
time would be received upon the exercise of the Warrant.

     (c) Certain Events. If any event occurs as to which the other provisions of this
Section 3 are not strictly applicable but the lack of any adjustment would not fairly
protect the purchase rights of the Holder under this Warrant in accordance with the basic intent
and principles of such provisions, or if strictly applicable would not fairly protect the purchase
rights of the Holder under this Warrant in accordance with the basic intent and principles of such
provisions, then the Company’s board of directors will, in good faith, make an appropriate
adjustment to protect the rights of the Holder; provided, however, that no such adjustment pursuant
to this Section 3(c) will increase the Exercise Price or decrease the number of Warrant
Shares as otherwise determined pursuant to this Section 3.

     (d) Adjustment of Exercise Price Upon Issuance of Additional Shares of Common Stock.
In the event the Company shall at any time prior to December 13, 2008, issue Additional Shares of
Common Stock (as defined below), without consideration or for a consideration per share less than
the Market Price in effect immediately prior to such issuance, then the Exercise Price shall be
reduced, concurrently with such issuance, to a price (calculated to the nearest one hundredth of a
cent) determined by multiplying such Market Price by a fraction, (A) the numerator of which shall
be (1) the number of shares of Common Stock outstanding immediately prior to such issue
plus (2) the number of Shares which the aggregate consideration received or to be received
by the Company for the total number of Additional Shares of Common Stock so issued or to be issued
would purchase at such Market Price; and (B) the denominator of which shall be the number of shares
of Common Stock outstanding immediately prior to such issuance plus the number of such
Additional Shares of Common Stock so issued in such issuance; provided that, for the
purpose of this Section 3(d), all shares of Common Stock issuable upon conversion or exchange of
convertible securities outstanding immediately prior to such issue shall be deemed to be
outstanding. If any issuance of Additional Shares of Common Stock shall require an adjustment to
the Exercise Price pursuant to the foregoing provisions of this Section 3(d), then,
effective at the time such adjustment is made, the number of Warrant Shares subject to purchase
upon exercise of this Warrant shall be increased to a number determined by multiplying the number
of Warrant Shares subject to purchase immediately before such Share Distribution by a fraction, the
numerator of which shall be the Exercise Price in effect immediately prior to such event and the
denominator of which shall be the Exercise Price as adjusted in accordance with this Section
3(d). The provisions of this Section 3(d) shall not operate to increase the Exercise
Price or reduce the number of Warrant Shares subject to purchase upon exercise of this Warrant.

5

 

For purposes of this Warrant, “Additional Shares of Common Stock” shall mean all shares of
Common Stock issued by the Company after the Effective Date (including without limitation any
shares of Common Stock issuable upon conversion or exchange of any convertible securities or upon
exercise of any option or warrant, on an as-converted basis), other than: (i) shares of Common
Stock issued or issuable upon conversion or exchange of any convertible securities or exercise of
any options outstanding on the Effective Date; (ii) shares of Common Stock issued or issuable by
reason of a dividend, stock split, split-up or other distribution on shares of Common Stock that is
covered by Sections 3(a)(i) through 3(a)(iii) above; or (iii) shares of Common
Stock (or options with respect thereto) issued or issuable to employees or directors of, or
consultants to, the Company or any of its subsidiaries pursuant to a plan, agreement or arrangement
approved by the Board of Directors of the Company. The provisions of this Section 3(d)
shall not operate to increase the Exercise Price.

4. TRANSFERS AND EXCHANGES OF WARRANT AND WARRANT SHARES

     (a) Registration of Transfers and Exchanges. Subject to Section 4(c) and
4(d), upon the Holder’s surrender of this Warrant, with a duly executed copy of the Assignment
Notice attached as Exhibit B , to the Secretary of the Company at its principal offices or
at such other office or agency as the Company may specify in writing to the Holder, the Company
shall register the transfer of all or any portion of this Warrant. Upon such registration of
transfer the Company shall issue a new Warrant, in substantially the form of this Warrant,
evidencing the acquisition rights transferred to the transferee and a new Warrant, in similar form,
evidencing the remaining acquisition rights not transferred, to the Holder requesting the transfer.

     (b) Warrant Exchangeable for Different Denominations. The Holder may exchange this
Warrant for a new Warrant or Warrants, in substantially the form of this Warrant, evidencing in the
aggregate the right to purchase the number of Warrant Shares which may then be purchased hereunder,
each of such new Warrants to be dated the date of such exchange and to represent the right to
purchase such number of Warrant Shares as shall be designated by the Holder. The Holder shall
surrender this Warrant with duly executed instructions regarding such re-certification of this
Warrant to the Secretary of the Company at its principal offices or at such other office or agency
as the Company may specify in writing to the Holder.

     (c) Restrictions on Transfers. This Warrant may not be transferred at any time
without (i) registration under the Act or (ii) an exemption from such registration and a written
opinion of legal counsel addressed to the Company that the proposed transfer of the Warrant may be
effected without registration under the Act, which opinion will be in form and from counsel
reasonably satisfactory to the Company. For the avoidance of doubt, this Warrant may be
transferred separately and independently from the Notes.

     (d) Permitted Transfers and Assignments. Notwithstanding any provision to the
contrary in this Section 4, the Holder may transfer, with or without consideration, this
Warrant or any of the Warrant Shares (or a portion thereof), and the Holder may cause Warrant
Shares to be issued upon exercise of any Warrant, to the Holder’s Affiliates without obtaining the
opinion from counsel that may be required by Section 4(c)(ii), provided that the Holder
delivers to the Company and its counsel certification, documentation, and other assurances
reasonably required by the Company’s counsel to enable the Company’s counsel to render an opinion
to the Company’s transfer agent that such transfer does not violate applicable securities laws.

     (e) The legend specified at the top of the first page of this Warrant shall also be placed on
all certificates issued upon transfer of, or in exchange for, or in lieu (pursuant to Section
5) of, this Warrant.

6

 

     (f) The Holder, by accepting this Warrant, consents and agrees with the Company and with every
subsequent Holder that, prior to due presentment of this Warrant for registration of transfer, the
Company may treat the Person in whose name this Warrant is registered as the owner thereof for all
purposes and as the Person entitled to exercise the rights granted under this Warrant, and neither
the Company nor any agent thereof shall be affected by any notice to the contrary.

5. MUTILATED OR MISSING WARRANT CERTIFICATE

If this Warrant is mutilated, lost, stolen or destroyed, upon request by the Holder, the Company
will, at its expense, issue, in exchange for and upon cancellation of the mutilated Warrant, or in
substitution for the lost, stolen or destroyed Warrant, a new Warrant, in substantially the form of
this Warrant, representing the right to acquire the equivalent number of Warrant Shares,
provided however, as a prerequisite to the issuance of a substitute Warrant, the
Company may require satisfactory evidence of loss, theft or destruction as well as an indemnity
from the Holder of a lost, stolen or destroyed Warrant.

6. PAYMENT OF TAXES

The Company will pay all transfer and stock issuance taxes attributable to the preparation,
issuance and delivery of this Warrant and the Warrant Shares (and replacement Warrants) including,
without limitation, all documentary and stamp taxes; provided, however, that the
Company shall not be required to pay any tax in respect of the transfer of this Warrant, or the
issuance or delivery of certificates for Warrant Shares or other securities in respect of the
Warrant Shares, to any person or entity other than to the Holder or its transferee.

7. FRACTIONAL WARRANT SHARES

No fractional Warrant Shares shall be issued upon exercise of this Warrant. The Company, in lieu
of issuing any fractional Warrant Share, shall round up the number of Warrant Shares issuable to
nearest whole share.

8. NO STOCK RIGHTS AND LEGEND

     (a) No holder of this Warrant Certificate, as such, shall be entitled to vote or be deemed the
holder of any other securities of the Company which may at any time be issuable on the exercise
hereof, nor shall anything contained herein be construed to confer upon the holder of this Warrant
Certificate, as such, the rights of a stockholder of the Company or the right to vote for the
election of directors or upon any matter submitted to stockholders at any meeting thereof, or give
or withhold consent to any corporate action or to receive notice of meetings or other actions
affecting stockholders (except as provided herein), or to receive dividends or subscription rights
or otherwise (except as provided herein).

     (b) Each certificate for Warrant Shares initially issued upon the exercise of this Warrant
Certificate, and each certificate for Warrant Shares issued to any subsequent transferee of any
such certificate, except for any Warrant Shares that (i) have been registered under the Securities
Act pursuant to Section 9 or (ii) transferred pursuant to Rule 144 or another exemption
therefrom pursuant to clause (ii) of Section 4(c) and with respect to which issuance or
transfer the opinion required under such clause (ii) is also to the effect that the following
legend is not required for the Company to establish compliance with any provision of the Securities
Act), shall be stamped or otherwise imprinted with a legend in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933,

7

 

AS AMENDED (THE “ACT”), OR ANY STATE SECURITIES LAWS, AND NEITHER
SUCH SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD,
PLEDGED, ASSIGNED OR OTHERWISE TRANSFERRED UNLESS (1) A REGISTRATION
STATEMENT WITH RESPECT THERETO IS EFFECTIVE UNDER THE ACT AND ANY
APPLICABLE STATE SECURITIES LAWS, OR (2) AN EXEMPTION FROM SUCH
REGISTRATION EXISTS AND THE COMPANY RECEIVES AN OPINION OF COUNSEL
TO THE HOLDER OF SUCH SECURITIES, WHICH COUNSEL AND OPINION ARE
REASONABLY SATISFACTORY TO THE COMPANY, THAT SUCH SECURITIES MAY BE
OFFERED, SOLD, PLEDGED, ASSIGNED OR TRANSFERRED IN THE MANNER
CONTEMPLATED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
ACT OR APPLICABLE STATE SECURITIES LAWS.”

9. REGISTRATION RIGHTS

     Neither the Warrant nor the Warrant Shares have been registered with the Commission under the
Securities Act or qualified for sale pursuant to any state blue sky law, and neither may be sold or
transferred without such registration or qualification, except pursuant to an exemption therefrom.
No rights shall be hereby granted which are in violation of applicable securities laws or
regulations.

     (a) Demand Registration.

          (i) At any time following March 31, 2008, upon delivery to the Company by the holder or
holders of at least 50% of all Warrants and Warrant Shares (such percentage determined by
aggregating the number of Warrant Shares into which Warrants are then exercisable and the number of
Warrant Shares then outstanding) (such holder or holders, the “Initiating Holders”) of a
written request (a “Registration Request”) that the Company effect a registration under the
Securities Act of Registrable Securities, which Registration Request shall specify the number of
Registrable Securities proposed to be sold (which number of Registrable Securities for all such
Initiating Holder(s) must aggregate at least 50% of the Warrant Shares as of such date), and the
intended method of disposition thereof, the Company will:

               (x) promptly (but in any case within ten (10) days) give written notice of such Registration
Request to all other holders of Warrants and to all other holders of Registrable Securities, which
holders shall be entitled to join such Registration Request by delivering to the Company within
thirty (30) days a notice specifying the number of Registrable Securities proposed to be sold and
the intended method of disposition thereof, in which case the term “Initiating Holders” shall
include such other holders and the Registration Request shall be deemed to cover such holders and
such number of Registrable Securities proposed to be sold by such holders; and

               (y) use its commercially reasonable efforts to effect, as expeditiously as practicable, the
registration of all Registrable Securities covered by such Registration Request;

provided that (A) subject to Section 9(a)(ii) the Company shall not be obligated to
effect a registration of Registrable Securities pursuant to the Warrants on more than one (1)
occasion for a Registration Request from the Holders (provided that in the event that
notwithstanding its best efforts, the Company is unable to register 100% of the Registrable
Securities in connection with such Registration Request by a Holder or Holders, the Holders shall
be entitled to one (1) additional Registration Request), (B) the Company shall not be obligated to
effect a registration of Registrable Securities pursuant hereto on more than one (1) occasion in
any six (6) month period, and (C) notwithstanding any provision to the contrary herein, the Company
may delay the filing of a registration statement for such Registrable Securities for a period

8

 

of up to ninety (90) days, measured from the date that the Company receives the applicable
Registration Request, by furnishing to each Initiating Holder within ten (10) Business Days of such
receipt a certified resolution of the Board of Directors of the Company stating that in the good
faith judgment of the Board it would be detrimental or otherwise disadvantageous to the Company and
its shareholders for such a registration statement to be filed at such time. If the Company
furnishes such certified resolution, the Initiating Holders may, in their discretion, elect to
relieve the Company of its obligation to proceed to effect the requested registration of the
Registrable Securities upon the expiration of the ninety (90) day period by withdrawing their
Registration Request.

          (ii) If the Initiating Holders or the Company so elect, the offering of the Registrable
Securities to be registered following a Registration Request shall be in the form of an
underwritten offering, in which case (x) the Initiating Holders and the Company shall mutually
agree upon and select the managing underwriters and any additional investment bankers and managers
to be used in connection with the offering; provided that if the Initiating Holders and the
Company cannot mutually agree, the Company will be entitled to select the managing underwriters and
additional investment bankers, but the managing underwriters and additional investment bankers so
selected must by reasonably satisfactory to the Initiating Holders, (y) the right of any Initiating
Holder to cause the Company to register its Registrable Securities pursuant to this Section
9(a) shall be conditioned upon the inclusion of such Initiating Holder’s Registrable Securities
in the underwriting (unless otherwise mutually agreed by such Initiating Holder and a majority in
interest of all Initiating Holders) to the extent provided herein and (z) all Initiating Holders
proposing to include their Registrable Securities in the registration and underwritten offering
shall enter into an underwriting agreement in customary form with the representative(s) of the
underwriters for such underwritten offering; provided further that the Company may
decline to have the offering of such Registrable Securities be in the form of an underwritten
offering, in which case such Registration Request shall not be counted as a Registration Request
for the purposes of the limitation on the number of Registration Requests contained in the proviso
to Section 9(a)(i); provided, further, the Company may not decline to have
the offering of any Registrable Securities pursuant to a Registration Request on more than one (1)
occasion in any twelve-month period, and the Holders may not make a second request for an
underwritten offering during this twelve-month period.

          (iii) Any registration statement filed pursuant to a Registration Request may include other
securities of the Company being sold for the account of the Company or for the account of any other
holders. If the representative(s) of the underwriters for an offering which includes any such
other securities advises the Company that marketing factors require a limitation on the amount of
securities to be underwritten, the amount of securities that shall be entitled to be included in
the registration and underwriting shall be allocated first to the Registrable Securities (and if
the limitation is such that the Registrable Securities held by all participating holders cannot be
so included, then the allocation shall be among the participating holders in proportion to the
Registrable Securities held by them), and second to securities being sold for the account of the
Company and any other holders.

     (b) Form S-3. The Company shall use its commercially reasonable efforts to qualify
and remain qualified to register securities on Form S-3 (or any successor form) under the
Securities Act. So long as the Company is qualified to register securities on Form S-3 (or any
successor form), the Initiating Holders shall have the right at any time and from time to time to
request registration on Form S-3 (or any successor form) for the Warrant Shares held by such
requesting Holder having an aggregate value of at least $500,000 (based on the then current market
price), including registrations for the sale of such Warrant Shares on a delayed or continuous
basis pursuant to Rule 415 under the Securities Act; provided, that the Company shall not
be obligated to register such Shares on more than two (2) occasions in any twelve-month period.
Such requests shall be in writing and shall state the number of Warrant Shares to be disposed of
and the intended method of disposition of such Shares by such Initiating Holders.

     (c) Piggyback Registration.

          (i) If any Registrable Securities are not able to be resold pursuant to an effective
Registration Statement and the Company, at any time or from time to time, proposes to file a
registration statement under the Securities Act with respect to an offering of Shares for cash (x)
for the Company’s own account (other than a registration statement on Form S-4 or S-8 (or any
successor or similar form that may be adopted by the Commission)) or (y) for the account of any
holders of Shares, Options, or Convertible Securities other than the Warrants and/or Warrant
Shares, then the Company at each such time shall give written notice of such proposed filing to
each Holder and to each holder of Registrable Securities (in no event less than twenty (20)
Business Days before the anticipated filing date), and such notice shall offer each Holder the
opportunity to register such number of Registrable Securities as such Holder may request, by
providing notice to the Company within ten (10) Business Days of the notice provided by the
Company, on the same terms and conditions as the other Shares to be included in such offering.

          (ii) If the registration of which the Company gives notice pursuant to this Section
9(c) is for an underwritten offering, (x) the notice provided by the Company shall so state,
(y) the right of any holder of Registrable Securities to cause the Company to register such
holders’ Registrable Securities pursuant to this Section 9(c) shall be conditioned upon the
inclusion of such holder’s Registrable Securities in the underwriting to the extent provided herein
and (z) all holders of Registrable Securities proposing to include its Registrable Securities in
the registration shall enter into an underwriting agreement in customary form (as agreed upon
between the Company and the underwriters selected by the Company for such an underwritten offering
with the representative(s) of the underwriters selected by the Company. The Company shall have no
obligation to consult with or obtain the consent of any Holder or any holder of Registrable
Securities in selecting any underwriters or investment bankers for an offering registered pursuant
to this Section 9(c).

          (iii) Notwithstanding any other provision of this Section 9(c), if an offering for
which the Company gives notice pursuant to Section 9(c)(i) is to be underwritten and the
managing underwriter for the offering advises the Company, in writing, that, in its opinion, the
number of Shares requested by the Holder to be included in such registration is likely to affect
materially and adversely the success of the offering or the price that would be received for any
Shares offered in such offering, then, notwithstanding anything in this Section 9 to the
contrary, the Company shall only be required to include in such registration, to the extent of the
number of Shares which the Company is so advised can be sold in such offering, (A) first, the
number of Shares requested to be included in such registration for the account of any stockholders
of the Company (including the Holder), pro rata among such stockholders on the basis of the number
of Shares that each of them has requested to be included in such registration, and (B) second, any
Shares proposed to be included in such registration for the account of the Company.

          (iv) The Company may withdraw its notice of proposed registration given pursuant to
Section 9(c)(i) at any time by giving written notice to each Holder and each holder of
Registrable Securities, whereupon the Company shall not be required to cause such proposed
registration to be effected.

     (d) Registration Procedures. Upon receipt of a request for registration of
Registrable Securities pursuant to Sections 9(a)-(c) the Company will thereupon use
its commercially reasonable efforts to effect the registration of the Registrable Securities that
are the subject of such request as expeditiously as possible, subject to the provisions of
Sections 9(a)-(c) and in connection therewith:

          (i) Use its commercially reasonable efforts to diligently and expeditiously prepare and file
with the SEC a Registration Statement on the appropriate form under the Securities Act with respect

10

 

to the Registrable Securities, which form shall comply as to form in all material respects
with the requirements of the applicable form and include all financial statements required by the
SEC to be filed therewith, and use its commercially reasonable efforts to cause such Registration
Statement to become and remain effective until completion of the proposed offering and sale of such
covered securities.

          (ii) (A) Furnish to the Holder copies of all documents filed with the SEC relating to the
registration of the Registrable Securities prior to their being filed with the SEC (and in any
event at least fifteen (15) Business Days prior to the filing), and (B) notify the Holder of any
stop order issued or threatened by the SEC and use commercially reasonable efforts to prevent the
entry of such stop order or to remove it if entered.

          (iii) (A) Prepare and file with the SEC such amendments and supplements, including
post-effective amendments, to each Registration Statement and the Prospectus used in connection
therewith as may be necessary to comply with the Securities Act and to keep the Registration
Statement continuously effective as required herein, and prepare and file with the SEC such
additional Registration Statements as necessary to register for resale under the Securities Act all
of the Registrable Securities (including naming any permitted transferees of Registrable Securities
as selling stockholders in such Registration Statement); (B) cause any related Prospectus to be
amended or supplemented by any required Prospectus supplement, and as so supplemented or amended to
be filed pursuant to Rule 424; (C) respond as promptly as possible to any comments received from
the SEC with respect to each Registration Statement or any amendment thereto and as promptly as
possible provide the Holder true and complete copies of all correspondence from and to the SEC
relating to the Registration Statement (other than correspondence containing material nonpublic
information); and (D) comply with the provisions of the Securities Act and the Exchange Act with
respect to the disposition of all Registrable Securities covered by such Registration Statement as
so amended or in such Prospectus as so supplemented.

          (iv) Notify the Holder as promptly as possible: (A) when the SEC notifies the Company whether
there will be a “review” of a Registration Statement and whenever the SEC comments in writing on
such Registration Statement; and (B) when a Registration Statement, or any post-effective amendment
or supplement thereto, has become effective, and after the effectiveness thereof (1) of any request
by the SEC or any other federal or state governmental authority for amendments or supplements to
the Registration Statement or Prospectus or for additional information; (2) of the issuance by the
SEC or any state securities commission of any stop order suspending the effectiveness of the
Registration Statement covering any or all of the Registrable Securities or the initiation of any
proceedings for that purpose; and (3) of the receipt by the Company of any notification with
respect to the suspension of the qualification or exemption from qualification of any of the
Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any
proceeding for such purpose. Without limitation of any remedies to which the Holder may be entitled
under this Agreement, if any of the events described in Section 9(d)(iv)(B)(1),
9(d)(iv)(B)(2), and 9(d)(iv)(B)(3) occur, the Company shall use its best efforts to
respond to and correct the event.

          (v) Notify the Holder and any underwriter as promptly as possible of the happening of any
event as a result of which the Prospectus included in or relating to a Registration Statement
contains an untrue statement of a material fact or omits any fact necessary to make the statements
therein not misleading; and, thereafter, the Company will as promptly as possible prepare (and,
when completed, give notice to the Holder) a supplement or amendment to such Prospectus so that, as
thereafter delivered to the purchasers of such Registrable Securities, such Prospectus will not
contain an untrue statement of a material fact or omit to state any fact necessary to make the
statements therein not misleading; provided that upon such notification by the Company, the Holder
will not offer or sell Registrable Securities pursuant to such Prospectus until the Company has
notified the Holder that it has prepared a supplement or amendment to such Prospectus and delivered
copies of such supplement or amendment to the Holder

11

 

(it being understood and agreed by the Company that the foregoing proviso shall in no way
diminish or otherwise impair the Company’s obligation to as promptly as possible prepare a
Prospectus amendment or supplement as above provided in this Section 9(d)(v) and deliver
copies of same as provided in Section 9(d)(ix) hereof).

          (vi) Upon the occurrence of any event described in Section 9(d)(v) hereof, as promptly as
possible, prepare a supplement or amendment, including a post-effective amendment, to the
Registration Statement or a supplement to the related Prospectus or any document incorporated or
deemed to be incorporated therein by reference, and file any other required document so that, as
thereafter delivered, neither the Registration Statement nor such Prospectus will contain an untrue
statement of a material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under which they are made,
not misleading.

          (vii) Use its commercially reasonable efforts to avoid the issuance of or, if issued, obtain
the withdrawal of, (A) any order suspending the effectiveness of any Registration Statement or (B)
any suspension of the qualification (or exemption from qualification) of any of the Registrable
Securities for sale in any jurisdiction, as promptly as possible.

          (viii) Furnish to the Holder, without charge, at least one conformed copy of each Registration
Statement and each amendment thereto, and all exhibits to the extent requested by the Holder
(including those previously furnished or incorporated by reference, and including an opinion letter
from counsel to the Company and a comfort letter from appropriate advisors in a form as are
customarily given and reasonably satisfactory to the Holder) as promptly as possible after the
filing of such documents with the SEC.

          (ix) Furnish to the selling Holder, without charge, such number of copies of a Prospectus,
including a preliminary Prospectus, in conformity with the requirements of the Securities Act, and
such other documents (including, without limitation, Prospectus amendments and supplements) as such
selling Holder may reasonably request in order to facilitate the disposition of the Registrable
Securities covered by such Prospectus and any amendment or supplement thereto. The Company hereby
consents to the use of such Prospectus and each amendment or supplement thereto by of the selling
Holder in connection with the offering and sale of the Registrable Securities covered by such
Prospectus and any amendment or supplement thereto to the extent permitted by federal and state
securities laws and regulations.

          (x) Use its commercially reasonable efforts to register and qualify (or obtain an exemption
from such registration and qualification) the Registrable Securities under such other securities or
blue sky laws of the states of residence of the Holder and such other jurisdictions as the Holder
shall reasonably request, to keep such registration or qualification (or exemption therefrom)
effective during the periods each Registration Statement is effective, and do any and all other
acts or things which may be reasonably necessary or advisable to enable the Holder to consummate
the public sale or other disposition of Registrable Securities in such jurisdiction, provided that
the Company shall not be required in connection therewith or as a condition thereto to qualify to
do business or to file a general consent to service of process in any such states or jurisdictions
where it is not then qualified or subject to process.

          (xi) Cooperate with the Holder to facilitate the timely preparation and delivery of
certificates representing the Registrable Securities to be delivered to a transferee pursuant to a
Registration Statement, which certificates shall be free, to the extent permitted by applicable
law, of all restrictive legends, and to enable such Registrable Securities to be in such
denominations and registered in such names as the Holder may request.

12

 

          (xii) Cooperate with any reasonable due diligence investigation undertaken by the Holder, any
managing underwriter participating in any disposition pursuant to a Registration Statement,
Holder’s counsels and any attorney, accountant or other agent retained by Holder or any managing
underwriter, in connection with the sale of the Registrable Securities, including, without
limitation, making available any documents and information; provided, however, that the Company
will not deliver or make available to the Holder material, nonpublic information unless the Holder
specifically requests and consents in advance in writing to receive such material, nonpublic
information and, if requested by the Company, the Holder agrees in writing to treat such
information as confidential.

          (xiii) Cause the Registrable Securities covered by such Registration Statement to be listed on
the securities exchange or quoted on the quotation system on which the Shares of the Company are
then listed or quoted (or if the Shares are not listed or quoted, then on such exchange or
quotation system as the selling holders of Registrable Securities and the Company shall determine).

          (xiv) Otherwise use its commercially reasonable efforts to comply with all applicable rules
and regulations of the SEC and make generally available to its security holders, in each case as
soon as practicable, but not later than thirty (30) days after the close of the period covered
thereby, an earnings statement of the Company which will satisfy the provisions of Section 1l(a) of
the Securities Act and Rule 158 thereunder (or any comparable successor provisions).

          (xv) Otherwise cooperate with the SEC and other regulatory agencies and take all actions and
execute and deliver or cause to be executed and delivered all documents necessary to effect the
registration of any Registrable Securities under this Warrant.

          (xvi) During the period when the Prospectus is required to be delivered under the Securities
Act, promptly file all documents required to be filed with the SEC pursuant to Sections 13(a),
13(c), 14, or 15(d) of the Exchange Act.

          (xvii) At the request of an Affiliate of the Holder, the Company shall amend any Registration
Statement to include such Affiliate as a selling stockholder in such Registration Statement.

          (xviii) Comply with all applicable rules and regulations of the SEC in all material respects.

     (e) Expenses Of Registration. The Company shall pay for all expenses incurred in
connection with a registration pursuant to this Warrant and compliance with Section 9(d) of
this Agreement, including without limitation (i) all registration, filing and qualification fees
and expenses (including without limitation those related to filings with the SEC, the NASD’s
Over-the-counter Bulletin Board, The Nasdaq Stock Market or any national securities exchange upon
which the Company’s securities are at such time listed and in connection with applicable state
securities or blue sky laws); provided that each party shall pay for its own underwriting fees,
discounts, commissions or transfer taxes, (ii) all printing expenses, (iii) all messenger,
telephone and delivery expenses incurred by the Company, (iv) all fees and disbursements of counsel
for the Company, and (v) reasonable fees and disbursements of counsel for the Holder and any
affiliates thereof that own Warrant Shares, in an aggregate amount not to exceed $25,000. In
addition, the Company shall be responsible for all of its internal expenses incurred in connection
with the consummation of the transactions contemplated by this Warrant, the expense of any annual
audit and audits of any significant acquisitions required to be included in the applicable
registration statement.

     (f) Delay Of Registration. Except as otherwise set forth herein, the Holder and the
Company (other than with respect to Section 9(d)(v) hereof) shall not take any action to
restrain, enjoin or otherwise

13

 

delay any registration as the result of any controversy which might arise with respect to the
interpretation or implementation of this Agreement.

     (g) Indemnification. In the event that any Registrable Securities of the Holder are
included in a Registration Statement pursuant to this Agreement:

          (i) To the fullest extent permitted by law, the Company will indemnify and hold harmless the
Holder and each officer, director, fiduciary, agent, investment advisor, employee, member (or other
equity holder), general partner and limited partner (and affiliates thereof) of the Holder, each
broker, underwriter or other person acting on behalf of the Holder and each Person, if any, who
controls the Holder within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act, against any losses, claims, damages, liabilities or actions, joint or several
(the “Losses”) to which they may become subject under the Securities Act or otherwise, insofar as
such Losses (or actions in respect thereof) arise out of or relate to any untrue or alleged untrue
statement of any material fact contained in the Registration Statement or any Prospectus relating
to Registrable Securities, or arise out of or relate to the omission or alleged omission to state
therein a material fact required to be stated therein, or necessary to make the statements therein
not misleading, or any violation by the Company of the Securities Act or state securities or blue
sky laws applicable to the Company and leading to action or inaction required of the Company in
connection with such registration or qualification under such Securities Act or state securities or
blue sky laws; and, subject to the provisions of Section 9(g)(iii) hereof, the Company will
reimburse on demand the Holder, such broker, underwriter or other person acting on behalf of the
Holder or such officer, director, fiduciary, employee, member (or other equity holder), manager,
general partner, limited partner, affiliate or controlling person for any legal or other expenses
reasonably incurred by any of them in connection with investigating or defending any such Losses;
provided, however, that the indemnity agreement contained in this Section
9(g)(i) shall not apply to amounts paid in settlement of any such Losses if such settlement is
effected without the consent of the Company (which consent shall not be unreasonably withheld), nor
shall the Company be liable in any such case for any such Loss to the extent that it solely arises
out of an untrue statement of any material fact contained in the Registration Statement or omission
to state therein a material fact required to be stated therein or necessary to make the statements
therein not misleading, in each case to the extent that such untrue statement or alleged untrue
statement or omission or alleged omission was made in the Registration Statement in reliance upon
and in conformity with written information furnished by the Holder with respect to the Holder
expressly for use in connection with such Registration Statement.

          (ii) To the fullest extent permitted by law, the Holder will indemnify and hold harmless the
Company, each of its directors, each of its officers who have signed the Registration Statement,
each person, if any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act, against any Losses to which the Company or any
such director, officer or controlling person may become subject to, under the Securities Act or
otherwise, insofar as such Losses solely arise out of any untrue statement of any material fact
contained in the Registration Statement, or solely arise out of the omission to state therein a
material fact required to be stated therein or necessary to make the statements therein not
misleading, in each case solely to the extent that such untrue statement or alleged untrue
statement or omission or alleged omission was made in the Registration Statement in reliance upon
and in conformity with written information furnished by the Holder with respect to the Holder
expressly for use in connection with such Registration Statement; and, subject to the provisions of
Section 9(g)(iv) hereof, the Holder will reimburse on demand any legal or other expenses
reasonably incurred by the Company or any such director, officer, or controlling person in
connection with investigating or defending any such Losses, provided, however, that
the maximum aggregate amount of liability of the Holder under this Section 9(g) shall be
limited to the proceeds (net of underwriting discounts and commissions, if any) actually received
by the Holder from the sale of Registrable Securities covered by such Registration Statement; and
provided, further, however, that the indemnity agreement

14

 

contained in this Section 9(g)(ii) or 9(g)(v) shall not apply to amounts paid
in settlement of any such Losses if such settlement is effected without the consent of the Holder
against which the request for indemnity is being made (which consent shall not be unreasonably
withheld), and that no selling Holder shall be required to indemnify any Person against any
liability arising from any untrue or misleading statement or omission contained in any preliminary
Prospectus if such deficiency is corrected in the final prospectus or for any liability which
arises out of the failure of any Person to deliver a Prospectus as required by the Securities Act.

          (iii) As promptly as possible after receipt by an indemnified party under this Section
9(g) of notice of the threat, assertion or commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against any indemnifying party under this
Section 9(g), notify the indemnifying party in writing of the commencement thereof and the
indemnifying party shall have the right to participate in and, to the extent the indemnifying party
desires, jointly with any other indemnifying party similarly noticed, to assume at its expense the
defense thereof with counsel mutually satisfactory to the parties; provided, however, that, the
failure to notify an indemnifying party promptly of the threat, assertion or commencement of any
such action shall not relieve such indemnifying party of any liability to the indemnified party
under this Section 9(g) except (and only) to the extent that it shall be finally determined
by a court of competent jurisdiction (which determination is not subject to appeal or further
review) that such failure shall have proximately and materially adversely prejudiced the
indemnifying party.

          (iv) If any indemnified party shall have reasonably concluded that there may be one or more
legal defenses available to such indemnified party which are different from or additional to those
available to the indemnifying party, or that such claim or litigation involves or could have an
effect upon matters beyond the scope of the indemnity agreement provided in this Section
9(g), the indemnifying party shall not have the right to assume the defense of such action on
behalf of such indemnified party, and such indemnifying party shall reimburse such indemnified
party and any person controlling such indemnified party for the fees and expenses of counsel
retained by the indemnified party which are reasonably related to the matters covered by the
indemnity agreement provided in this Section 9(g). Subject to the foregoing, an indemnified
party shall have the right to employ separate counsel in any such action and to participate in the
defense thereof but the fees and expenses of such counsel shall not be at the expense of the
Company.

          (v) If the indemnification provided for in this Section 9(g) from the indemnifying
party is applicable by its terms but unavailable to an indemnified party hereunder in respect of
any Losses, then the indemnifying party, in lieu of indemnifying such indemnified party, shall,
subject to the maximum aggregate liability of the Holder as set forth in Section 9(g)(ii),
contribute to the amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and indemnified party in connection with the actions which
resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative faults of such indemnifying party and indemnified party
shall be determined by reference to, among other things, whether any action in question, including
any untrue or alleged untrue statement of a material fact or omission or alleged omission to state
a material fact, has been made by, or relates to information supplied by, such indemnifying party
or indemnified party, and the parties’ relative intent, knowledge, access to information and
opportunity to correct or prevent such action. The amount paid or payable by a party as a result
of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to
include, subject to the limitations set forth in Sections 9(g)(i), 9(g)(ii),
9(g)(iii) and 9(g)(iv), any legal or other fees, charges or expenses reasonably
incurred by such party in connection with any investigation or proceeding. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be
entitled to contribution from any person. The parties hereto agree that it would not be just and

15

 

equitable if contribution pursuant to this Section 9(g)(v) were determined by pro rata
allocation or by any other method of allocation which does not take account of the equitable
considerations referred to in the immediately preceding paragraph.

          (vi) The indemnity and contribution agreements contained in this Section 9(g) are in
addition to any liability that any indemnifying party may have to any indemnified party.

     (h) Lock Up. In connection with an underwritten public offering of Shares of the
Company registered pursuant to the Securities Act, if the managing underwriter for such
registration shall so request, the holders of Registrable Securities shall not sell, make any short
sale of, grant any option for the purchase of, or otherwise dispose of any Registrable Securities
(other than those Shares included in such registration) without the prior written consent of the
Company for a period designated by the Company in writing to the holders of Registrable Securities,
which period shall begin not more than twenty (20) days prior to the effectiveness of the
registration statement pursuant to which such public offering shall be made and shall not last more
than 180 days after the effective date of such registration statement; provided that no
holder of Registrable Securities shall be subject to such restriction unless and only to the extent
all of the officers, directors, Affiliates and all holders of 1% or more holders are subject to,
and remain subject to, a written agreement including the same restrictions.

     (i) Reports Under The Exchange Act. With a view to making available to the Holder the
benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit the
Holder to sell the Registrable Securities to the public without registration, the Company shall:
(i) make and keep public information available, as those terms are understood and defined in Rule
144; (ii) file with the SEC in a timely manner all reports and other documents required to be filed
by an issuer of securities registered under the Securities Act or the Exchange Act; (iii) as long
as the Holder owns any Shares, Warrants or Warrant Shares, to furnish in writing upon the Holder’s
request a written statement by the Company that it has complied with the reporting requirements of
Rule 144 and of the Securities Act and the Exchange Act, and to furnish to the Holder a copy of the
most recent annual and quarterly reports of the Company, and such other reports and documents so
filed by the Company as may be reasonably requested in availing the Holder of any rule or
regulation of the SEC permitting the selling of any such Shares, Warrants or Warrant Shares without
registration; and (iv) undertake any additional actions reasonably necessary to maintain the
availability of a Registration Statement, including any successor or substitute forms, or the use
of Rule 144.

Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall submit the
disputed determinations or arithmetic calculations via facsimile within two (2) Business Days of

the Holder and the Company are unable to agree upon such determination or calculation of the
Exercise Price or the Warrant Shares within three (3) Business Days of such disputed determination
or arithmetic calculation being submitted to the Holder, then the Company shall, within two (2)
Business Days submit via facsimile the disputed determination of the Exercise Price to an
independent, reputable investment bank selected by the Company and approved by the Holder. The
Company shall cause, at its expense, the investment bank to perform the determinations or
calculations and notify the Company and the Holder of the results no later than ten (10) Business

or accountant’s determination or calculation, as the case may be, shall be binding upon all parties
absent demonstrable error.

17

 

     (b) Appraisal.

          (i) At least 20 days prior to an event requiring a determination of the Appraised Value of a
Share, the Board of Directors shall determine the Appraised Value acting reasonably and in good
faith, providing notice of such determination to the Requisite Holders. In the event the Requisite
Holders object to such Appraised Value by delivering written notice to the Board of Directors
within thirty (30) days, then the Appraised Value shall be determined as set forth in clause (ii)
below.

          (ii) The Company shall, within ten (10) days after the above-referenced thirty (30) day
period, engage an independent investment bank of national repute (the “Appraiser”) selected
by the Company (with the consent of the Requisite Holders, such consent not to be unreasonably
withheld) and retained pursuant to an engagement letter between the Company and the Appraiser with

2. LOAN AND TERMS OF PAYMENT.

     2.1 Revolver Advances.

          (a) Subject to the terms and conditions of this Agreement, and during the term of this
Agreement, each Lender with a Revolver Commitment agrees (severally, not jointly or jointly and
severally) to make advances (“Advances”) to Borrowers in an amount at any one time
outstanding not to exceed such Lender’s Pro Rata Share of an amount equal to the lesser of (i) the
Maximum Revolver Amount less the Letter of Credit Usage at such time less the sum of (x) the Bank
Product Reserve and (y) the aggregate amount of reserves, if any, established by Agent under
Section 2.1 (b), and (ii) the Borrowing Base at such time less the Letter of Credit Usage
at such time.

          (b) Anything to the contrary in this Section 2.1 notwithstanding, Agent shall have the
right to establish reserves against the then-existing Borrowing Base or the Maximum Revolver Amount
in such amounts, and with respect to such matters, as Agent in its Permitted Discretion shall deem
necessary or appropriate, including reserves with respect to (i) sums that Parent or its
Subsidiaries are required to pay under any Section of this Agreement or any other Loan Document
(such as taxes, assessments, insurance premiums, or, in the case of leased assets, rents or other
amounts payable under such leases) and have failed to pay, and (ii) amounts owing by Parent or its
Subsidiaries to any Person to the extent secured by a Lien on, or trust over, any of the Collateral
(including proceeds thereof or collections from the sale of Hydrocarbons which may from time to
time come into the possession of Lenders or their agent(s)) (other than a Permitted Lien), which
Lien or trust, in the Permitted Discretion of Agent likely would have a priority superior to
Agent’s Liens (such as Liens or trusts in favor of landlords, warehousemen, carriers, mechanics,
materialmen, laborers, or suppliers, or Liens or trusts for ad valorem, excise, sales, or other
taxes where given priority under applicable law) in and to such item of the Collateral. Consistent
with the foregoing, the Borrowers acknowledge that the Agent is to reserve $12,500,000 against the
Borrowing Base until such time as the conditions set forth in Section 5.24 are satisfied.

          (c) For the period from and including the Closing Date to but excluding the first
Redetermination Date, the amount of the Borrowing Base shall be $25,000,000, subject to adjustment
as provided in Section 2.1(b). Notwithstanding the foregoing, the Borrowing Base may be
subject to further adjustments from time to time pursuant to Section 5.21(d) or clause (g)
of the definition of “Permitted Dispositions.”

          (d) The Borrowing Base shall be redetermined semi-annually in accordance with this Section
2.1 (each, a “Scheduled Redetermination”), and subject to Section 2.1(d), such
redetermined Borrowing Base shall become effective and applicable to Borrowers, Agent, the Issuing
Lenders and the Lenders on the date of the New Borrowing Base Notice. In addition, Administrative
Borrower may, by notifying Agent thereof, and Agent may, at the direction of the Required Lenders,
by notifying Administrative Borrower thereof, one time during any 12-month period, each elect to
cause the

- 2 -

 

Borrowing Base to be redetermined between Scheduled Redeterminations (an “Interim
Redetermination”) in accordance with this Section 2.1.

               (i) Each Scheduled Redetermination and each Interim Redetermination shall be effectuated as
follows: Upon receipt by Agent of (A) the Reserve Report and the certificate required to be
delivered by Administrative Borrower to Agent, in the case of a Scheduled Redetermination, pursuant
to Sections 5.20(a) and (c), and, in the case of an Interim Redetermination,
pursuant to Sections 5.20(b) and (c), and (B) such other reports, data and
supplemental information, including, without limitation, the information provided pursuant to
Section 5.20(c), as may, from time to time, be reasonably requested by Agent or any Lender
(the Reserve Report, such certificate and such other reports, data and supplemental information
being the “Engineering Reports”), Agent shall evaluate the information contained in the
Engineering Reports and shall, in good faith, propose a new Borrowing Base (the “Proposed
Borrowing Base”), based upon the Reserve Reports and such other information (including, without
limitation, the status of title information with respect to the Oil and Gas Properties as described
in the Engineering Reports and the existence of any other Indebtedness) as Agent deems appropriate
in its Permitted Discretion. In no event shall the Proposed Borrowing Base exceed the Maximum
Revolver Amount.

               (ii) Agent shall notify Administrative Borrower and the Lenders of the Proposed Borrowing Base
(the “Proposed Borrowing Base Notice”):

                    (A) in the case of a Scheduled Redetermination (a) if Agent shall have received the
Engineering Reports required to be delivered by Administrative Borrower pursuant to Sections
5.20(a) and (c) in a timely and complete manner, then on or before April 30th and
October 31st of such year following the date of delivery or (b) if Agent shall not have received
the Engineering Reports required to be delivered by Administrative Borrower pursuant to
Sections 5.20(a) and (c) in a timely and complete manner, then promptly after Agent
has received complete Engineering Reports from Administrative Borrower and has had a reasonable
opportunity to determine the Proposed Borrowing Base in accordance with Section 2.1(d)(i);
provided, that if such Engineering Reports are not delivered as required pursuant to Sections
5.20(a) and (c), until the next Scheduled Redetermination, Agent shall determine the
Borrowing Base in its sole discretion, subject to the provisions of Section 2.1(d)(iii);
and

                    (B) in the case of an Interim Redetermination, promptly, and in any event, within thirty (30)
days after Agent has received the required Engineering Reports from Administrative Borrower.

               (iii) Any Proposed Borrowing Base that would increase the Borrowing Base then in effect must
be approved or deemed to have been approved by all of the Lenders as provided in this
Section 2.1(d)(iii) and any Proposed Borrowing Base that would maintain or decrease the
Borrowing Base then in then in effect must be approved or deemed to have been approved by the
Required Lenders as provided in this Section 2.1(d)(iii). Upon receipt of the Proposed
Borrowing Base Notice, each Lender shall have fifteen (15) days to agree with the Proposed
Borrowing Base or disagree with the Proposed Borrowing Base by proposing an alternate Borrowing
Base. If at the end of such fifteen (15) days, any Lender has not communicated its approval or
disapproval in writing to Agent, such silence shall be deemed to be an approval of the Proposed
Borrowing Base. If, at the end of such 15-day period, all of the Lenders, in the case of a
Proposed Borrowing Base that would increase the Borrowing Base then in effect, or the Required
Lenders, in the case of a Proposed Borrowing Base that would decrease or maintain the Borrowing
Base then in effect, have approved or deemed to have approved, as aforesaid, then the Proposed
Borrowing Base shall become the new Borrowing Base and made available to Borrowers, effective on
the date the New Borrowing Base Notice is provided under Section 2.1(d)(iii)(A). If,
however, at the end of such 15-day period, all of the Lenders or the Required Lenders, as
applicable, have not approved or deemed to have approved, as aforesaid, then Agent shall poll the
Lenders to ascertain the

- 3 -

 

highest Borrowing Base then acceptable to all of the Lenders or the Required Lenders and, so
long as such amount does not increase the Borrowing Base then in effect, such amount shall become
the new Borrowing Base, effective on the date the New Borrowing Base Notice is provided under in
Section 2.1(d)(iii)(A).

                    (A) After a redetermined Borrowing Base is approved or is deemed to have been approved by all
of the Lenders or the Required Lenders pursuant to Section 2.1(d)(iii), Agent shall notify
Administrative Borrower and the Lenders of the amount of the redetermined Borrowing Base (the
“New Borrowing Base Notice”), and such amount shall become the new Borrowing Base,
effective and applicable to Borrowers, Agent, the Issuing Lenders and the Lenders.

               (iv) Within three (3) Business Days after receipt from Agent of the New Borrowing Base Notice,
Borrowers shall have the right to request that the Required Lenders reduce the Borrowing Base until
the next Scheduled Redetermination Date or Interim Redetermination Date occurs by giving written
notification to Agent (which shall promptly notify the Lenders); and with the consent of the
Required Lenders the Borrowing Base will be the amount set forth in such notice until the next
Scheduled Redetermination Date or Interim Redetermination Date (subject to adjustment under
Section 5.21(d) or clause (g) of the definition of “Permitted Dispositions”).

          (e) Amounts borrowed pursuant to this Section 2.1 may be repaid and, subject to the
terms and conditions of this Agreement, reborrowed at any time during the term of this Agreement.
The outstanding principal amount of the Advances, together with interest accrued and unpaid
thereon, shall be due and payable on the Maturity Date or, if earlier, on the date on which they
are declared due and payable pursuant to the terms of this Agreement.

     2.2 Term Loan. Subject to the terms and conditions of this Agreement, on the Closing Date
each Lender with a Term Loan Commitment agrees (severally, not jointly or jointly and severally) to
make term loans (collectively, the “Term Loan”) to Borrowers in an amount equal to such
Lender’s Pro Rata Share of the Term Loan Amount. The principal of the Term Loan shall be repaid in
accordance with Section 2.4(c)(iii)(D), with the outstanding unpaid principal balance and
all accrued and unpaid interest on the Term Loan becoming due and payable on the earliest of (i)
the Maturity Date, (ii) the date of the acceleration of the Term Loan in accordance with the terms
hereof, and (iii) the date of termination of this Agreement pursuant to Section 8.1(d).
All principal of, interest on, and other amounts payable in respect of the Term Loan shall
constitute Obligations.

     2.3 Borrowing Procedures and Settlements.

          (a) Procedure for Borrowing. Each Borrowing shall be made by an irrevocable written request
by an Authorized Person delivered to Agent. Unless Swing Lender is not obligated to make a Swing
Loan pursuant to Section 2.3(b) below, such notice must be received by Agent no later than
1:00 p.m. (Georgia time) on the Business Day that is the requested Funding Date specifying (i) the
amount of such Borrowing, and (ii) the requested Funding Date, which shall be a Business Day;
provided, however, that if Swing Lender is not obligated to make a Swing Loan as to
a requested Borrowing, such notice must be received by Agent no later than 1:00 p.m. (Georgia time)
on the Business Day prior to the date that is the requested Funding Date. At Agent’s election, in
lieu of delivering the above-described written request, any Authorized Person may give Agent
telephonic notice of such request by the required time. In such circumstances, Borrowers agree
that any such telephonic notice will be confirmed in writing within 24 hours of the giving of such
telephonic notice, but the failure to provide such written confirmation shall not affect the
validity of the request.

          (b) Making of Swing Loans. In the case of a request for an Advance and so long as either (i)
the aggregate amount of Swing Loans made since the last Settlement Date, minus the amount of
Collections or payments applied to Swing Loans since the last Settlement Date, plus the amount of
the requested Advance does not exceed $5,000,000, or (ii) Swing Lender, in its sole discretion,
shall agree to make a Swing Loan notwithstanding the foregoing limitation, Swing Lender shall make
an Advance in the amount of such Borrowing (any such Advance made solely by Swing Lender pursuant
to this Section 2.3(b) being referred to as a “Swing Loan” and such Advances being
referred to collectively as “Swing Loans”) available to Borrowers on the Funding Date
applicable thereto by transferring immediately available funds to Borrowers’ Designated Account.
Each Swing Loan shall be deemed to be an Advance hereunder and shall be subject to all the terms
and conditions applicable to other Advances, except that all payments on any Swing Loan shall be
payable to Swing Lender solely for its own account. Subject to the provisions of Section
2.3(d)(ii), Swing Lender shall not make and shall not be obligated to make any Swing Loan if
Swing Lender has actual knowledge that (i) one or more of the applicable conditions precedent set
forth in Section 3 will not be satisfied on the requested Funding Date for the applicable
Borrowing, or (ii) the requested Borrowing would exceed the Availability on such Funding Date.
Swing Lender shall not otherwise be required to determine whether the applicable conditions
precedent set forth in Section 3 have been satisfied on the Funding Date applicable thereto
prior to making any Swing Loan. The Swing Loans shall be secured by Agent’s Liens, constitute
Obligations hereunder, and bear interest at the rate applicable from time to time to Advances that
are Base Rate Loans.

          (c) Making of Loans.

               (i) In the event that Swing Lender is not obligated to make a Swing Loan and does not elect to
make a Swing Loan it is not obligated to make, then promptly after receipt of a request for a
Borrowing pursuant to Section 2.3(a), Agent shall notify the Lenders, not later than 1:00
p.m. (Georgia time) on the Business Day immediately preceding the Funding Date applicable thereto,
by telecopy, telephone, or other similar form of transmission, of the requested Borrowing. Each
Lender shall make the amount of such Lender’s Pro Rata Share of the requested Borrowing available
to Agent in immediately available funds, to Agent’s Account, not later than 1:00 p.m. (Georgia
time) on the Funding Date applicable thereto. After Agent’s receipt of the proceeds of such
Advances, Agent shall make the proceeds thereof available to Administrative Borrower on the
applicable Funding Date by transferring immediately available funds equal to such proceeds received
by Agent to Administrative Borrower’s Designated Account; provided, however, that,
subject to the provisions of Section 2.3(d)(ii), Agent shall not request any Lender to
make, and no Lender shall have the obligation to make, any Advance if Agent shall have actual
knowledge that (1) one or more of the applicable conditions precedent set forth in Section
3 will not be satisfied on the requested Funding Date for the applicable Borrowing unless such

- 5 -

 

condition has been waived, or (2) the requested Borrowing would exceed the Availability on
such Funding Date.

               (ii) Unless Agent receives notice from a Lender prior to 9:00 a.m. (Georgia time) on the date
of a Borrowing, that such Lender will not make available as and when required hereunder to Agent
for the account of Borrowers the amount of that Lender’s Pro Rata Share of the Borrowing, Agent may
assume that each Lender has made or will make such amount available to Agent in immediately
available funds on the Funding Date and Agent may (but shall not be so required), in reliance upon
such assumption, make available to Borrowers on such date a corresponding amount. If and to the
extent any Lender shall not have made its full amount available to Agent in immediately available
funds and Agent in such circumstances has made available to Borrowers such amount, that Lender
shall on the Business Day following such Funding Date make such amount available to Agent, together
with interest at the Defaulting Lender Rate for each day during such period. A notice submitted by
Agent to any Lender with respect to amounts owing under this subsection shall be conclusive, absent
manifest error. If such amount is so made available, such payment to Agent shall constitute such
Lender’s Advance on the date of Borrowing for all purposes of this Agreement. If such amount is
not made available to Agent on the Business Day following the Funding Date, Agent will notify
Administrative Borrower of such failure to fund and, upon demand by Agent, Borrowers shall pay such
amount to Agent for Agent’s account, together with interest thereon for each day elapsed since the
date of such Borrowing, at a rate per annum equal to the interest rate applicable at the time to
the Advances composing such Borrowing. The failure of any Lender to make any Advance on any
Funding Date shall not relieve any other Lender of any obligation hereunder to make an Advance on
such Funding Date, but no Lender shall be responsible for the failure of any other Lender to make
the Advance to be made by such other Lender on any Funding Date.

               (iii) Agent shall not be obligated to transfer to a Defaulting Lender any payments made by
Borrowers to Agent for the Defaulting Lender’s benefit, and, in the absence of such transfer to the
Defaulting Lender, Agent shall transfer any such payments to each other non-Defaulting Lender
member of the Lender Group ratably in accordance with their Commitments (but only to the extent
that such Defaulting Lender’s Advance was funded by the other members of the Lender Group) or, if
so directed by Administrative Borrower and if no Default or Event of Default had occurred and is
continuing (and to the extent such Defaulting Lender’s Advance was not funded by the Lender Group),
retain same to be re-advanced to Borrowers as if such Defaulting Lender had made Advances to
Borrowers. Subject to the foregoing, Agent may hold and, in its Permitted Discretion, re-lend to
Borrowers for the account of such Defaulting Lender the amount of all such payments received and
retained by Agent for the account of such Defaulting Lender. Solely for the purposes of voting or
consenting to matters with respect to the Loan Documents, such Defaulting Lender shall be deemed
not to be a “Lender” and such Lender’s Commitment shall be deemed to be zero. This Section shall
remain effective with respect to such Lender until (x) the Obligations under this Agreement shall
have been declared or shall have become immediately due and payable, (y) the non-Defaulting
Lenders, Agent, and Administrative Borrower shall have waived such Defaulting Lender’s default in
writing, or (z) the Defaulting Lender makes its Pro Rata Share of the applicable Advance and pays
to Agent all amounts owing by Defaulting Lender in respect thereof. The operation of this Section
shall not be construed to increase or otherwise affect the Commitment of any Lender, to relieve or
excuse the performance by such Defaulting Lender or any other Lender of its duties and obligations
hereunder, or to relieve or excuse the performance by Borrowers of their duties and obligations
hereunder to Agent or to the Lenders other than such Defaulting Lender. Any such failure to fund
by any Defaulting Lender shall constitute a material breach by such Defaulting Lender of this
Agreement and shall entitle Administrative Borrower at its option, upon written notice to Agent, to
arrange for a substitute Lender to assume the Commitment of such Defaulting Lender, such substitute
Lender to be acceptable to Agent. In connection with the arrangement of such a substitute Lender,
the Defaulting Lender shall have no right to refuse to be

- 6 -

 

replaced hereunder, and agrees to execute and deliver a completed form of Assignment and
Acceptance in favor of the substitute Lender (and agrees that it shall be deemed to have executed
and delivered such document if it fails to do so) subject only to being repaid its share of the
outstanding Obligations (other than Bank Product Obligations, but including an assumption of its
Pro Rata Share of the Risk Participation Liability) but without any premium or penalty of any kind
whatsoever; provided, however, that any such assumption of the Commitment of such
Defaulting Lender shall not be deemed to constitute a waiver of any of the Lender Groups’ or
Borrowers’ rights or remedies against any such Defaulting Lender arising out of or in relation to
such failure to fund.

          (d) Protective Advances and Optional Overadvances.

               (i) Agent hereby is authorized by Borrowers and the Lenders, from time to time in Agent’s sole
discretion, (A) after the occurrence and during the continuance of a Default or an Event of
Default, or (B) at any time that any of the other applicable conditions precedent set forth in
Section 3 are not satisfied, to make Advances to Borrowers on behalf of the Lenders that
Agent, in its Permitted Discretion deems necessary or desirable (1) to preserve or protect the
Collateral, or any portion thereof, (2) to enhance the likelihood of repayment of the Obligations
(other than the Bank Product Obligations), or (3) to pay any other amount chargeable to Borrowers
pursuant to the terms of this Agreement, including Lender Group Expenses and the costs, fees, and
expenses described in Section 9 (any of the Advances described in this
Section 2.3(d)(i) shall be referred to as “Protective Advances”).

               (ii) Any contrary provision of this Agreement notwithstanding, the Lenders hereby authorize
Agent or Swing Lender, as applicable, and either Agent or Swing Lender, as applicable, may, but is
not obligated to, knowingly and intentionally, continue to make Advances (including Swing Loans) to
Borrowers notwithstanding that an Overadvance exists or thereby would be created, so long as (A)
after giving effect to such Advances, the outstanding Revolver Usage does not exceed the Borrowing
Base by more than $3,000,000, and (B) after giving effect to such Advances, the outstanding
Revolver Usage (except for and excluding amounts charged to the Loan Account for interest, fees, or
Lender Group Expenses) does not exceed the Maximum Revolver Amount. In the event Agent obtains
actual knowledge that the Revolver Usage exceeds the amounts permitted by the immediately foregoing
provisions, regardless of the amount of, or reason for, such excess, Agent shall notify the Lenders
as soon as practicable (and prior to making any (or any additional) intentional Overadvances
(except for and excluding amounts charged to the Loan Account for interest, fees, or Lender Group
Expenses) unless Agent determines that prior notice would result in imminent harm to the Collateral
or its value), and the Lenders with Revolver Commitments thereupon shall, together with Agent,
jointly determine the terms of arrangements that shall be implemented with Borrowers intended to
reduce, within a reasonable time, the outstanding principal amount of the Advances to Borrowers to
an amount permitted by the preceding sentence. In such circumstances, if any Lender with a
Revolver Commitment objects to the proposed terms of reduction or repayment of any Overadvance, the
terms of reduction or repayment thereof shall be implemented according to the determination of the
Required Lenders. Each Lender with a Revolver Commitment shall be obligated to settle with Agent
as provided in Section 2.3(e) for the amount of such Lender’s Pro Rata Share of any
unintentional Overadvances by Agent reported to such Lender, any intentional Overadvances made as
permitted under this Section 2.3(d)(ii), and any Overadvances resulting from the charging
to the Loan Account of interest, fees, or Lender Group Expenses.

               (iii) Each Protective Advance and each Overadvance shall be deemed to be an Advance hereunder,
except that no Protective Advance or Overadvance shall be eligible to be a LIBOR Rate Loan and,
prior to Settlement therefor, all payments on the Protective Advances shall be payable to Agent
solely for its own account. The Protective Advances and Overadvances shall be repayable on demand,
secured by Agent’s Liens, constitute Obligations hereunder, and bear interest at the rate
applicable from time to time to Advances that are Base Rate Loans. The provisions of this
Section 

- 7 -

 

2.3(d) are for the exclusive benefit of Agent, Swing Lender, and the Lenders and are
not intended to benefit Borrower in any way.

          (e) Settlement. It is agreed that each Lender’s funded portion of the Advances is intended by
the Lenders to equal, at all times, such Lender’s Pro Rata Share of the outstanding Advances. Such
agreement notwithstanding, Agent, Swing Lender, and the other Lenders agree (which agreement shall
not be for the benefit of any Borrower) that in order to facilitate the administration of this
Agreement and the other Loan Documents, settlement among the Lenders as to the Advances, the Swing
Loans, and the Protective Advances shall take place on a periodic basis in accordance with the
following provisions:

               (i) Agent shall request settlement (“Settlement”) with the Lenders on a weekly basis,
or on a more frequent basis if so determined by Agent (1) on behalf of Swing Lender, with respect
to the outstanding Swing Loans, (2) for itself, with respect to the outstanding Protective
Advances, and (3) with respect to Parent and its Subsidiaries’ Collections or payments received, as
to each by notifying the Lenders by telecopy, telephone, or other similar form of transmission, of
such requested Settlement, no later than 2:00 p.m. (Georgia time) on the Business Day immediately
prior to the date of such requested Settlement (the date of such requested Settlement being the
“Settlement Date”). Such notice of a Settlement Date shall include a summary statement of
the amount of outstanding Advances, Swing Loans, and Protective Advances for the period since the
prior Settlement Date. Subject to the terms and conditions contained herein (including
Section 2.3(c)(iii)): (y) if a Lender’s balance of the Advances (including Swing Loans and
Protective Advances) exceeds such Lender’s Pro Rata Share of the Advances (including Swing Loans
and Protective Advances) as of a Settlement Date, then Agent shall, by no later than 3:00 p.m.
(Georgia time) on the Settlement Date, transfer in immediately available funds to a Deposit Account
of such Lender (as such Lender may designate), an amount such that each such Lender shall, upon
receipt of such amount, have as of the Settlement Date, its Pro Rata Share of the Advances
(including Swing Loans and Protective Advances), and (z) if a Lender’s balance of the Advances
(including Swing Loans and Protective Advances) is less than such Lender’s Pro Rata Share of the
Advances (including Swing Loans and Protective Advances) as of a Settlement Date, such Lender shall
no later than 12:00 p.m. (Georgia time) on the Settlement Date transfer in immediately available
funds to the Agent’s Account, an amount such that each such Lender shall, upon transfer of such
amount, have as of the Settlement Date, its Pro Rata Share of the Advances (including Swing Loans
and Protective Advances). Such amounts made available to Agent under clause (z) of the immediately
preceding sentence shall be applied against the amounts of the applicable Swing Loans or Protective
Advances and, together with the portion of such Swing Loans or Protective Advances representing
Swing Lender’s Pro Rata Share thereof, shall constitute Advances of such Lenders. If any such
amount is not made available to Agent by any Lender on the Settlement Date applicable thereto to
the extent required by the terms hereof, Agent shall be entitled to recover for its account such
amount on demand from such Lender together with interest thereon at the Defaulting Lender Rate.

               (ii) In determining whether a Lender’s balance of the Advances, Swing Loans, and Protective
Advances is less than, equal to, or greater than such Lender’s Pro Rata Share of the Advances,
Swing Loans, and Protective Advances as of a Settlement Date, Agent shall, as part of the relevant
Settlement, apply to such balance the portion of payments actually received in good funds by Agent
with respect to principal, interest, fees payable by Borrowers and allocable to the Lenders
hereunder, and proceeds of Collateral. To the extent that a net amount is owed to any such Lender
after such application, such net amount shall be distributed by Agent to that Lender as part of
such next Settlement.

               (iii) Between Settlement Dates, Agent, to the extent Protective Advances or Swing Loans are
outstanding, may pay over to Agent or Swing Lender, as applicable, any Collections or

- 8 -

 

payments received by Agent, that in accordance with the terms of this Agreement would be
applied to the reduction of the Advances, for application to the Protective Advances or Swing
Loans. Between Settlement Dates, Agent, to the extent no Protective Advances or Swing Loans are
outstanding, may pay over to Swing Lender any payments received by Agent, that in accordance with
the terms of this Agreement would be applied to the reduction of the Advances, for application to
Swing Lender’s Pro Rata Share of the Advances. If, as of any Settlement Date, Collections of
Parent or its Subsidiaries received since the then immediately preceding Settlement Date have been
applied to Swing Lender’s Pro Rata Share of the Advances other than to Swing Loans, as provided for
in the previous sentence, Swing Lender shall pay to Agent for the accounts of the Lenders, and
Agent shall pay to the Lenders, to be applied to the outstanding Advances of such Lenders, an
amount such that each Lender shall, upon receipt of such amount, have, as of such Settlement Date,
its Pro Rata Share of the Advances. During the period between Settlement Dates, Swing Lender with
respect to Swing Loans, Agent with respect to Protective Advances, and each Lender (subject to the
effect of agreements between Agent and individual Lenders) with respect to the Advances other than
Swing Loans and Protective Advances, shall be entitled to interest at the applicable rate or rates
payable under this Agreement on the daily amount of funds employed by Swing Lender, Agent, or the
Lenders, as applicable.

          (f) Notation. Agent shall record on its books the principal amount of the Advances (or
portion of the Term Loan, as applicable) owing to each Lender, including the Swing Loans owing to
Swing Lender, and Protective Advances owing to Agent, and the interests therein of each Lender,
from time to time and such records shall, absent manifest error, conclusively be presumed to be
correct and accurate.

          (g) Lenders’ Failure to Perform. All Advances (other than Swing Loans and Protective
Advances) shall be made by the Lenders contemporaneously and in accordance with their Pro Rata
Shares. It is understood that (i) no Lender shall be responsible for any failure by any other
Lender to perform its obligation to make any Advance (or other extension of credit) hereunder, nor
shall any Commitment of any Lender be increased or decreased as a result of any failure by any
other Lender to perform its obligations hereunder, and (ii) no failure by any Lender to perform its
obligations hereunder shall excuse any other Lender from its obligations hereunder.

     2.4 Payments.

          (a) Payments by Borrower.

               (i) Except as otherwise expressly provided herein, all payments by Borrowers shall be made to
Agent’s Account for the account of the Lender Group and shall be made in immediately available
funds, no later than 2:00 p.m. (Georgia time) on the date specified herein. Any payment received by
Agent later than 2:00 p.m. (Georgia time) shall be deemed to have been received on the following
Business Day and any applicable interest or fee shall continue to accrue until such following
Business Day.

               (ii) Unless Agent receives notice from Administrative Borrower prior to the date on which any
payment is due to the Lenders that Borrowers will not make such payment in full as and when
required, Agent may assume that Borrowers have made (or will make) such payment in full to Agent on
such date in immediately available funds and Agent may (but shall not be so required), in reliance
upon such assumption, distribute to each Lender on such due date an amount equal to the amount then
due such Lender. If and to the extent Borrowers do not make such payment in full to Agent on the
date when due, each Lender severally shall repay to Agent on demand such amount distributed to such
Lender, together with interest thereon at the Defaulting Lender Rate for each day from the date
such amount is distributed to such Lender until the date repaid.

- 9 -

 

          (b) Apportionment and Application.

               (i) So long as no Event of Default has occurred and is continuing and except as otherwise
provided with respect to Defaulting Lenders who would otherwise be entitled to receive such
payments as provided herein, all principal and interest payments shall be apportioned ratably among
the applicable Lenders (according to the unpaid principal balance of the Obligations to which such
payments relate held by each Lender) and all payments of fees and expenses (other than fees or
expenses that are for Agent’s separate account) shall be apportioned ratably among the Lenders
having a Pro Rata Share of the type of Commitment or Obligation to which a particular fee or
expense relates. Except as otherwise specifically provided in Section 2.4(b)(iv) hereof or
in Section 2.4(d) hereof, all payments to be made hereunder by Borrowers shall be remitted
to Agent and, subject to Section 2.4(b)(iv), all such payments, and all proceeds of
Collateral received by Agent, shall be applied, so long as no Event of Default has occurred and is
continuing, to reduce the balance of the Advances outstanding or to make scheduled payments to
repay the Term Loan as provided herein and, thereafter, to Borrowers (to be wired to the Designated
Account) or such other Person entitled thereto under applicable law.

               (ii) At any time that an Event of Default has occurred and is continuing and except as
otherwise provided with respect to Defaulting Lenders, all payments remitted to Agent and all
proceeds of Collateral received by Agent shall be applied as follows:

                    (A) first, to pay any Lender Group Expenses (including cost or expense reimbursements)
or indemnities then due to Agent under the Loan Documents, until paid in full,

                    (B) second, to pay any fees or premiums then due to Agent under the Loan Documents
until paid in full,

                    (C) third, to pay interest due in respect of all Protective Advances until paid in
full,

                    (D) fourth, to pay the principal of all Protective Advances until paid in full,

                    (E) fifth, ratably to pay any Lender Group Expenses (including cost or expense
reimbursements) or indemnities then due to any of the Lenders under the Loan Documents, until paid
in full,

                    (F) sixth, ratably to pay any fees or premiums then due to any of the Lenders with a
Revolver Commitment or holding any Advance, until paid in full,

                    (G) seventh, ratably to pay interest due in respect of the Advances (other than
Protective Advances), and the Swing Loans, until paid in full,

                    (H) eighth, ratably (i) to pay the principal of all Swing Loans until paid in full,
(ii) to pay the principal of all Advances until paid in full, (iii) to Agent, to be held by Agent,
for the ratable benefit of Issuing Lender and those Lenders having a Revolver Commitment or holding
any Advance, as cash collateral in an amount up to 105% of the Letter of Credit Usage, (iv) to
Agent, to be held by Agent, for the benefit of the Bank Product Providers, as cash collateral in an
amount up to 105% of the amount of Bank Product Obligations in respect of Swap Agreements, and (v)
to Agent to be held by Agent for the benefit of the Bank Product Obligations as cash collateral in
an amount not to exceed the amount set forth in clause (II) of the definition of Bank Product
Reserve established prior to the occurrence of, and not in contemplation of, the subject Event of
Default,

- 10 -

 

                    (I) ninth, ratably to pay any fees or premiums then due to any of the Lenders with a
Term Loan Commitment or holding any Term Loan, until paid in full,

                    (J) tenth, ratably to pay interest due in respect of the Term Loan, until paid in
full,

                    (K) eleventh, to pay the outstanding principal balance of the Term Loan (in the
inverse order of the maturity of the installments due thereunder) until the Term Loan is paid in
full,

                    (L) twelfth, to pay any other Obligations (including the provision of amounts to
Agent, to be held by Agent, for the benefit of the Bank Product Providers, as cash collateral in an
amount up to the amount determined by Agent in its Permitted Discretion as the amount necessary to
secure Parent’s and its Subsidiaries’ obligations in respect of Bank Products), and

                    (M) thirteenth, to Borrowers (to be wired to the Designated Account) or such other
Person entitled thereto under applicable law.

               (iii) Agent promptly shall distribute to each Lender, pursuant to the applicable wire
instructions received from each Lender in writing, such funds as it may be entitled to receive,
subject to a Settlement delay as provided in Section 2.3(e).

               (iv) In each instance, so long as no Event of Default has occurred and is continuing,
Section 2.4(b)(i) shall not apply to any payment made by Borrowers to Agent and specified
by Borrowers to be for the payment of specific Obligations then due and payable (or prepayable)
under any provision of this Agreement.

               (v) For purposes of Section 2.4(b)(ii) other than clause (L)), “paid in full” means
payment of all amounts owing under the Loan Documents according to the terms thereof, including
loan fees, service fees, professional fees, interest (and specifically including interest accrued
after the commencement of any Insolvency Proceeding), default interest, interest on interest, and
expense reimbursements, whether or not any of the foregoing (other than disallowed interest and
disallowed loan fees, if any) would be or is allowed or disallowed in whole or in part in any
Insolvency Proceeding; provided, however, that for the purposes of Section 2.4(b)(ii)(L),
“paid in full” means payment of all amounts owing under the Loan Documents according to the terms
hereof, including loan fees, service fees, professional fees, interest (and specifically including
interest accrued after the commencement of any Insolvency Proceeding), default interest, interest
on interest, and expense reimbursements, whether or not any of the foregoing would be or is allowed
or disallowed in whole or in party in any Insolvency Proceeding.

               (vi) In the event of a direct conflict between the priority provisions of this Section
2.4 and any other provision contained in any other Loan Document, it is the intention of the
parties hereto that such provisions be read together and construed, to the fullest extent possible,
to be in concert with each other. In the event of any actual, irreconcilable conflict that cannot
be resolved as aforesaid, the terms and provisions of this Section 2.4 shall control and
govern.

          (c) Prepayments.

               (i) If at any time the sum of the aggregate principal amount of the outstanding Advances, the
outstanding Letter of Credit Usage, the Bank Product Reserve and the aggregate amount of reserves,
if any, established by Agent under Section 2.1 exceeds the lesser of (x) the

- 11 -

 

Borrowing Base and (y) the Maximum Revolver Amount, Borrowers shall prepay the Obligations in
an amount equal to such excess which prepayments shall be applied in the manner set forth in
Section 2.4(d).

               (ii) Optional Prepayments of the Term Loan. The Term Loan may be voluntarily prepaid
in full or in part at any time; provided that (x) no Event of Default shall have occurred or be
continuing either immediately before or immediately after such prepayment and (y) there shall be at
least $10,000,000 of Availability both immediately before and immediately after such prepayment.
Any such principal prepayments shall be applied to the outstanding principal amount of the Term
Loans in inverse order of maturity. Each such prepayment shall be in an amount which is an integral
multiple of $5,000,000 or any greater amount which is a multiple of $500,000, shall be made by
Borrowers and shall be irrevocable.

               (iii) Mandatory Prepayments.

                    (A) Immediately upon the receipt by Parent or any of its Subsidiaries of the proceeds of any
voluntary or involuntary sale or disposition by Parent or any of its Subsidiaries of property or
assets (including casualty losses or condemnations but excluding sales or dispositions which
qualify as Permitted Dispositions under clauses (a), (b), (c), (d), (e) or (f) of the definition of
Permitted Dispositions), Borrowers shall prepay the outstanding principal amount of the Obligations
in accordance with Section 2.4(d) in an amount equal to 100% of the Net Cash Proceeds
(including condemnation awards and payments in lieu thereof) received by such Person in connection
with such sales or dispositions; provided that, so long as (A) no Default or Event of
Default shall have occurred and is continuing, (B) Administrative Borrower shall have given Agent
prior written notice of Borrowers’ intention to apply such monies to the costs of replacement of
the properties or assets that are the subject of such sale or disposition, (C) the monies are held
in a cash collateral account in which Agent has a perfected first-priority security interest, and
(D) Parent or its Subsidiaries, as applicable, complete such replacement within 180 days after the
initial receipt of such monies, Parent and its Subsidiaries shall have the option to apply such
monies to the costs of replacement of the property or assets that are the subject of such sale or
disposition unless and to the extent that such applicable period shall have expired without such
replacement, purchase or construction being made or completed, in which case, any amounts remaining
in the cash collateral account shall be paid to Agent and applied in accordance with Section
2.4(d). Nothing contained in this Section 2.4(c)(iii)(A) shall permit Parent or any of
its Subsidiaries to sell or otherwise dispose of any property or assets other than in accordance
with Section 6.4.

                    (B) Immediately upon the receipt by Parent or any of its Subsidiaries of any Extraordinary
Receipts, Borrowers shall prepay the outstanding principal amount of the Obligations in accordance
with Section 2.4(d) in an amount equal to 100% of such Extraordinary Receipts, net of any
reasonable expenses incurred in collecting such Extraordinary Receipts.

                    (C) Immediately upon the issuance or incurrence by Parent or any of its Subsidiaries of any
Indebtedness (other than Indebtedness permitted under Section 6.1(a), (b),
(c), (d), (e), (f) or (g)) or the issuance by Parent or any
of its Subsidiaries of any shares of Parent’s Stock or its Subsidiaries’ Stock (other than (I) in
the event that Parent or any of its Subsidiaries forms a Subsidiary in accordance with the terms
hereof, the issuance by such Subsidiary of Stock to a Borrower or such Subsidiary, as applicable
and (II) the issuance by Parent of the Warrant or of shares of its Stock (including the Warrant
Shares) to holders of warrants or options existing on the Closing Date and set forth on
Schedule 4.5(b)), Borrowers shall prepay the outstanding principal amount of the
Obligations in accordance with Section 2.4(d) in an amount equal to (x) 100% of the Net
Cash Proceeds received by such Person in connection with such incurrence of Indebtedness or such
issuance of Stock if such Stock is issued in a transaction other than as described in clause (y)
below, or (y) 50% of the Net Cash Proceeds received by such Person in connection with an issuance
of Stock in an underwritten public offering

- 12 -

 

pursuant to a registration statement filed with the SEC (other than a registration statement
on Form S-8) or an issuance to not less than 10 investors under Section 4(2) and/or Regulation D
under the Securities Act of 1933, as amended; provided the applicable Person intends in good faith
to register the securities represented by such issuance with the SEC as soon as possible. The
provisions of this Section 2.4(c)(iii) shall not be deemed to be implied consent to any
such issuance or incurrence otherwise prohibited by the terms and conditions of this Agreement.

                    (D) Within 10 days of delivery to Agent and the Lenders of either (1) audited annual financial
statements or (2) the unaudited quarterly balance sheet, income statement and statement of cash
flow, as applicable, pursuant to Section 5.3, commencing with the delivery to Agent and the
Lenders of the financial statements for Parent’s fiscal year ended December 31, 2009 (for the
period from the second anniversary of the Closing Date to and including December 31, 2009) or, if
such financial statements are not delivered to Agent and the Lenders on the date such statements
are required to be delivered pursuant to Section 5.3, within 10 days after the date such
statements are required to be delivered to Agent and the Lenders pursuant to Section 5.3,
Borrowers shall prepay the outstanding principal amount of the Obligations in accordance with
Section 2.4(d) in an amount equal to 50% of (1) with respect to the first fiscal quarter of
2010, the Excess Cash Flow of Parent and its Subsidiaries for the last fiscal quarter of Parent’s
fiscal year ended December 31, 2009, and (2) with respect to each subsequent fiscal quarter, the
Excess Cash Flow of Parent and its Subsidiaries for the fiscal quarter immediately preceding such
fiscal quarter.

          (d) Application of Payments. Each prepayment pursuant to any clause of Section
2.4(c)(iii) above shall (A) so long as no Event of Default shall have occurred and be
continuing and subject to the last sentence of this subsection, be applied, first, to the
outstanding principal amount of the Advances, but solely to the extent necessary to increase the
Availability at such time to $10,000,000, second, to the outstanding principal amount of the Term
Loan until paid in full, third, to the outstanding principal amount of the Advances (with a
corresponding permanent reduction in the Maximum Revolver Amount and a permanent reserve against
the Borrowing Base) until paid in full, and fourth, to cash collateralize the Letters of Credit in
an amount equal to 105% of the then extant Letter of Credit Usage (with a corresponding permanent
reduction in the Maximum Revolver Amount and a permanent reserve against the Borrowing Base), and
(B) if an Event of Default shall have occurred and be continuing, be applied in the manner set
forth in Section 2.4(b)(ii). Each such prepayment of the Term Loan shall be applied
against the remaining installments of principal of the Term Loan in the inverse order of maturity.
Notwithstanding the foregoing, any prepayment resulting from the sale of any Collateral comprising
the Borrowing Base shall be applied first to the outstanding principal amount of the Advances, and
then to the Term Loans to be apportioned among the Term Loan Lenders pro rata.

     2.5 Overadvances

If, at any time or for any reason, the amount of Obligations owed by Borrowers to the Lender
Group pursuant to Section 2.1 or Section 2.12 is greater than any of the
limitations set forth in Section 2.1 or Section 2.12, as applicable (an
“Overadvance”), Borrowers immediately upon demand shall pay to Agent, in cash, the amount
of such excess, which amount shall be used by Agent to reduce the Obligations in accordance with
the priorities set forth in Section 2.4(b). Borrowers promise to pay the Obligations
(including principal, interest, fees, costs, and expenses) in Dollars in full on the Maturity Date
or, if earlier, on the date on which the Obligations are declared due and payable pursuant to the
terms of this Agreement.

     2.6 Interest Rates and Letter of Credit Fee: Rates, Payments, and Calculations.

- 13 -

 

          (a) Interest Rates. Except as provided in Section 2.6(c), all Obligations (except for
undrawn Letters of Credit and except for Bank Product Obligations) that have been charged to the
Loan Account pursuant to the terms hereof shall bear interest on the Daily Balance thereof as
follows:

               (i) if the relevant Obligation is an Advance that is (A) a LIBOR Rate Loan, at a per annum
rate equal to the LIBOR Rate plus the LIBOR Rate Margin applicable to an Advance (except to the
extent an Advance is converted from a LIBOR Rate Loan to a Base Rate Loan pursuant to Section
2.13(a))or (B) a Base Rate Loan, at a per annum rate equal to the Base Rate plus the Base Rate
Margin applicable to an Advance; or

               (ii) if the relevant Obligation relates to the Term Loan that is (A) a LIBOR Rate Loan, at a
per annum rate equal to (a) the LIBOR Rate plus the LIBOR Rate Margin applicable to the Term Loan;
provided that if an event described in Section 2.13(d)(ii) shall occur, the interest on the Term
Loan shall accrue at a per annum rate equal to the Base Rate plus the Base Rate Margin applicable
to the Term Loan or (B) a Base Rate Loan, at a per annum rate equal to the Base Rate plus the Base
Rate Margin applicable to an Advance.

          (b) Letter of Credit Fee. Borrowers shall pay Agent (for the ratable benefit of the Lenders
with a Revolver Commitment, subject to any agreements between Agent and individual Lenders), a
Letter of Credit fee (in addition to the charges, commissions, fees, and costs set forth in
Section 2.12(e)) which shall accrue at a rate equal to 2.0% per annum times the Daily
Balance of the undrawn amount of all outstanding Letters of Credit.

          (c) Default Rate. Upon the occurrence and during the continuation of an Event of Default (and
at the election of Agent or the Required Lenders),

               (i) all Obligations (except for undrawn Letters of Credit and except for Bank Product
Obligations) that have been charged to the Loan Account pursuant to the terms hereof shall bear
interest on the Daily Balance thereof at a per annum rate equal to 2 percentage points above the
per annum rate otherwise applicable hereunder, and

               (ii) the Letter of Credit fee provided for in Section 2.6(b) shall be increased to 2
percentage points above the per annum rate otherwise applicable hereunder.

          (d) Payment. Except as provided to the contrary in Section 2.11 or Section
2.13(a), interest, Letter of Credit fees, and all other fees payable hereunder shall be due and
payable, in arrears, on the first day of each calendar quarter at any time that Obligations or
Commitments are outstanding. Borrowers hereby authorize Agent, from time to time without prior
notice to Borrowers, to charge all interest and fees (when due and payable), all Lender Group
Expenses (as and when incurred), all charges, commissions, fees, and costs provided for in
Section 2.12(e) (as and when accrued or incurred), all fees and costs provided for in
Section 2.11 (as and when accrued or incurred), and all other payments as and when due and
payable under any Loan Document (including the amounts due and payable with respect to the Term
Loan and including any amounts due and payable to the Bank Product Providers in respect of Bank
Products up to the amount of the Bank Product Reserve) to Borrowers’ Loan Account, which amounts
thereafter shall constitute Advances hereunder and shall accrue interest at the rate then
applicable to Advances that are Base Rate Loans. Any interest not paid when due shall be
compounded by being charged to the Loan Account and shall thereafter constitute Advances hereunder
and shall accrue interest at the rate then applicable to Advances that are Base Rate Loans;
provided, however, that if at the time that any amounts due in respect of interest on the Term Loan
are charged to Borrowers’ Loan Account, an Event of Default or Overadvance exists, or would result
therefrom, such amounts shall not constitute Advances but instead shall continue to remain
outstanding as amounts due in

- 14 -

 

respect of the Term Loan, and such amounts shall be compounded and added to the outstanding
principal balance of the Term Loan; provided further, however, that the failure to make any such
payment and the compounding of such interest shall nonetheless constitute an Event of Default under
Section 7.1.

          (e) Computation. All interest and fees chargeable under the Loan Documents shall be computed
on the basis of a 360 day year for the actual number of days elapsed. In the event the Base Rate
is changed from time to time hereafter, the rates of interest hereunder based upon the Base Rate
automatically and immediately shall be increased or decreased by an amount equal to such change in
the Base Rate.

          (f) Intent to Limit Charges to Maximum Lawful Rate. In no event shall the interest rate or
rates payable under this Agreement, plus any other amounts paid in connection herewith, exceed the
highest rate permissible under any law that a court of competent jurisdiction shall, in a final
determination, deem applicable. Borrowers and the Lender Group, in executing and delivering this
Agreement, intend legally to agree upon the rate or rates of interest and manner of payment stated
within it; provided, however, that, anything contained herein to the contrary
notwithstanding, if said rate or rates of interest or manner of payment exceeds the maximum
allowable under applicable law, then, ipso facto, as of the date of this Agreement, Borrowers are
and shall be liable only for the payment of such maximum as allowed by law, and payment received
from Borrowers in excess of such legal maximum, whenever received, shall be applied to reduce the
principal balance of the Obligations to the extent of such excess. Without limiting the foregoing,
it is the intention of the parties hereto that the Agent and each Lender shall conform strictly to
usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be
usurious as to the Agent or any Lender under laws applicable to it (including the laws of the
United States of America and the State of Texas or any other jurisdiction whose laws may be
mandatorily applicable to the Agent or such Lender notwithstanding the other provisions of this
Agreement), then, in that event, notwithstanding anything to the contrary in any of the Loan
Documents or any agreement entered into in connection with or as security for the Loans, it is
agreed as follows: (a) the aggregate of all consideration with constitutes interest under law
applicable to the Agent or any Lender that is contracted for, taken, reserved, charged or received
by the Agent or such Lender under any of the Loan Documents or agreements or otherwise in
connection with the Loans shall under no circumstances exceed the maximum amount allowed by such
applicable law, and any excess shall be canceled automatically and if theretofore paid shall be
credited by the Agent or such Lender on the principal amount of the Indebtedness (or, to the extent
that the principal amount of the Indebtedness shall have been or would thereby be paid in full,
refunded by the Agent or such Lender to the borrowers; and (b) in the event that the maturity of
the Loans is accelerated by reason of an election of the holder thereof resulting from any Event of
Default under this Agreement or otherwise, or in the event of any required or permitted prepayment,
then such consideration that constitutes interest under law applicable to the Agent or any Lender
may never include more than the maximum amount allowed by such applicable law, and excess interest,
if any provided for in this Agreement or otherwise shall be canceled automatically by the Agent or
such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be
credited by the Agent or such Lender on the principal amount of the Indebtedness (or, to the extent
that the principal amount of the Indebtedness shall have been or would thereby be paid in full,
refunded by the Agent or such Lender to the Borrowers). All sums paid or agreed to be paid to the
Agent or any Lender for the use, forbearance or detention of sums due hereunder shall, to the
extent permitted by law applicable to the Agent or such Lender, be amortized, prorated, allocated
and spread throughout the stated term of the Loans until payment in full so that the rate or amount
of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such
applicable law. If at any time and from time to time (i) the amount of interest payable to the
Agent or any Lender on any date shall be computed at the maximum rate allowable under law
applicable to the Agent or such Lender pursuant to this Section 2.6(f) and (ii) in respect
of any subsequent interest computation period the amount of interest otherwise payable to the Agent
or such Lender would be less than the amount of interest payable to the Agent or

- 15 -

 

such Lender computed at the maximum rate allowable under law applicable to the Agent or such
Lender, then the amount of interest payable to the Agent or such Lender in respect of such
subsequent interest computation period shall continue to be computed at the maximum lawful rate
applicable to the Agent or such Lender until the total amount of interest payable to the Agent or
such Lender shall equal the total amount of interest which would have been payable to the Agent or
such Lender if the total amount of interest had been computed without giving effect to this
Section 2.6(f). To the extent that Chapter 303 of the Texas Finance Code is relevant for
the purpose of determining the maximum lawful rate applicable to the Agent or a Lender, the Agent
or such Lender elects to determine the applicable rate ceiling under such Chapter by the weekly
ceiling from time to time in effect. Chapter 346 of the Texas Finance Code does not apply to any
Borrower’s obligations hereunder.

     2.7 Cash Management.

          (a) Parent shall and shall cause each of its Subsidiaries to (i) establish and maintain cash
management services of a type and on terms satisfactory to Agent at one or more of the banks set
forth on Schedule 2.7(a) (each a “Cash Management Bank”), and shall request in
writing and otherwise take such reasonable steps to ensure that all of its and its Subsidiaries’
Account Debtors forward payment of the amounts owed by them directly to such Cash Management Bank,
and (ii) deposit or cause to be deposited promptly, and in any event no later than the first
Business Day after the date of receipt thereof, all of their Collections (including those sent
directly by their Account Debtors to Parent or its Subsidiaries) into a bank account in Agent’s
name (a “Cash Management Account”) at one of the Cash Management Banks. Agent reserves the
right, in its sole discretion, to require that any amounts received in any Cash Management Account
which may represent amounts that constitute trust funds (i.e., production taxes, severance taxes,
or payroll taxes) or amounts attributable to interests of third Persons such as overriding royalty
interest be segregated by such Cash Management Bank and held in a separate account or otherwise as
directed by Agent.

          (b) Each Cash Management Bank shall establish and maintain Control Agreements with Agent and
Borrowers. Each such Control Agreement shall provide, among other things, that (i) the Cash
Management Bank will comply with any instructions originated by Agent directing the disposition of
the funds in such Cash Management Account without further consent by Parent or its Subsidiaries, as
applicable, (ii) the Cash Management Bank has no rights of setoff or recoupment or any other claim
against the applicable Cash Management Account other than for payment of its service fees and other
charges directly related to the administration of such Cash Management Account and for returned
checks or other items of payment, and (iii) upon the instruction of the Agent (an “Activation
Instruction”), it will forward by daily sweep all amounts in the applicable Cash Management
Account to the Agent’s Account. Agent agrees not to issue an Activation Instruction with respect
to the Cash Management Accounts or to give instructions to the Cash Management Bank directing the
disposition of funds in a Cash Management Account unless a Triggering Event has occurred and is
continuing at such time.

          (c) So long as no Default or Event of Default has occurred and is continuing, Administrative
Borrower may amend Schedule 2.7(a) to add or replace a Cash Management Bank or Cash
Management Account; provided, however, that (i) such prospective Cash Management
Bank shall be reasonably satisfactory to Agent, and (ii) prior to the time of the opening of such
Cash Management Account, Parent (or its Subsidiary, as applicable) and such prospective Cash
Management Bank shall have executed and delivered to Agent a Control Agreement. Parent (or its
Subsidiaries, as applicable) shall close any of their Cash Management Accounts (and establish
replacement cash management accounts in accordance with the foregoing sentence) promptly and in any
event within 30 days of notice from Agent that the creditworthiness of any Cash Management Bank is
no longer acceptable in Agent’s reasonable judgment, or as promptly as practicable and in any event
within 60 days of notice from Agent

- 16 -

 

that the operating performance, funds transfer, or availability procedures or performance of
the Cash Management Bank with respect to Cash Management Accounts or Agent’s liability under any
Control Agreement with such Cash Management Bank is no longer acceptable in Agent’s reasonable
judgment.

          (d) Each Cash Management Account shall be a cash collateral account subject to a Control
Agreement.

     2.8 Crediting Payments. The receipt of any payment item by Agent (whether from
transfers to Agent by the Cash Management Banks pursuant to the Control Agreements or otherwise)
shall not be considered a payment on account unless such payment item is a wire transfer of
immediately available federal funds made to the Agent’s Account or unless and until such payment
item is honored when presented for payment. Should any payment item not be honored when presented
for payment, then Borrowers shall be deemed not to have made such payment and interest shall be
calculated accordingly. Anything to the contrary contained herein notwithstanding, any payment
item shall be deemed received by Agent only if it is received into the Agent’s Account on a
Business Day on or before 2:00 p.m. (Georgia time). If any payment item is received into the
Agent’s Account on a non-Business Day or after 2:00 p.m. (Georgia time) on a Business Day, it shall
be deemed to have been received by Agent as of the opening of business on the immediately following
Business Day; provided, however, Agent reserves the right, in its sole discretion, to exclude from
such provisional reduction and payment the amount of any such payments that Agent determines may
constitute trust funds (e.g., production taxes, severance taxes, or payroll taxes) or amounts
attributable to interests of third Persons such as overriding royalty interests.

     2.9 Designated Account. Agent is authorized to make the Advances, and Issuing Lender is
authorized to issue the Letters of Credit, under this Agreement based upon telephonic or other
instructions received from anyone purporting to be an Authorized Person or, without instructions,
if pursuant to Section 2.6(d). Administrative Borrower agrees to establish and maintain
the Designated Account with the Designated Account Bank for the purpose of receiving the proceeds
of the Advances requested by Borrowers and made by Agent or the Lenders hereunder. Unless
otherwise agreed by Agent and Administrative Borrower, any Advance, Protective Advance, or Swing
Loan requested by Borrowers and made by Agent or the Lenders hereunder shall be made to the
Designated Account.

     2.10 Maintenance of Loan Account; Statements of Obligations. Agent shall maintain an
account on its books in the name of Borrowers (the “Loan Account”) on which Borrowers will be
charged with the Term Loan, all Advances (including Protective Advances and Swing Loans) made by
Agent, Swing Lender, or the Lenders to Borrowers or for Borrowers’ account, the Letters of Credit
issued by Issuing Lender for Borrowers’ account, and with all other payment Obligations hereunder
or under the other Loan Documents (except for Bank Product Obligations), including, accrued
interest, fees and expenses, and Lender Group Expenses. In accordance with Section 2.8,
the Loan Account will be credited with all payments received by Agent from Borrowers or for
Borrowers’ account, including all amounts received in the Agent’s Account from any Cash Management
Bank. Agent shall render statements regarding the Loan Account to Administrative Borrower,
including principal, interest, fees, and including an itemization of all charges and expenses
constituting Lender Group Expenses owing, and such statements, absent manifest error, shall be
conclusively presumed to be correct and accurate and constitute an account stated between Borrowers
and the Lender Group unless, within 30 days after receipt thereof by Administrative Borrower,
Administrative Borrower shall deliver to Agent written objection thereto describing the error or
errors contained in any such statements. Promptly after receipt of such written objection and
Agent’s evaluation thereof, the Agent shall credit the Loan Account for amounts (if any) contained
in such statements that Agent agrees were charged in error.

     2.11 Fees. Borrowers shall pay to Agent, as and when due and payable under the terms of
the Fee Letter, the fees set forth in the Fee Letter.

- 17 -

 

     2.12 Letters of Credit.

          (a) Subject to the terms and conditions of this Agreement, the Issuing Lender agrees to issue
letters of credit for the account of Borrowers (each, an “L/C”) or to purchase
participations or execute indemnities or reimbursement obligations (each such undertaking, an
“L/C Undertaking”) with respect to letters of credit issued by an Underlying Issuer (as of
the Closing Date, the prospective Underlying Issuer is to be Wells Fargo) for the account of
Borrowers. Each request for the issuance of a Letter of Credit, or the amendment, renewal, or
extension of any outstanding Letter of Credit, shall be made in writing by an Authorized Person and
delivered to the Issuing Lender and Agent via hand delivery, telefacsimile, or other electronic
method of transmission reasonably in advance of the requested date of issuance, amendment, renewal,
or extension. Each such request shall be in form and substance satisfactory to the Issuing Lender
in its Permitted Discretion and shall specify (i) the amount of such Letter of Credit, (ii) the
date of issuance, amendment, renewal, or extension of such Letter of Credit, (iii) the expiration
date of such Letter of Credit, (iv) the name and address of the beneficiary thereof (or the
beneficiary of the Underlying Letter of Credit, as applicable), and (v) such other information
(including, in the case of an amendment, renewal, or extension, identification of the outstanding
Letter of Credit to be so amended, renewed, or extended) as shall be necessary to prepare, amend,
renew, or extend such Letter of Credit. If requested by the Issuing Lender, Borrowers also shall
be an applicant under the application with respect to any Underlying Letter of Credit that is to be
the subject of an L/C Undertaking. The Issuing Lender shall have no obligation to issue a Letter
of Credit if any of the following would result after giving effect to the issuance of such
requested Letter of Credit:

               (i) the Letter of Credit Usage would exceed the Borrowing Base less the outstanding amount of
Advances, less the Bank Product Reserve, and less the aggregate amount of reserves, if any,
established by Agent under Section 2.1(b), or

               (ii) the Letter of Credit Usage would exceed $5,000,000, or

               (iii) the Letter of Credit Usage would exceed the Maximum Revolver Amount less the outstanding
amount of Advances less the Bank Product Reserve, and less the aggregate amount of reserves, if
any, established by Agent under Section 2.1(b).

          Each Letter of Credit (and corresponding Underlying Letter of Credit) shall be in form and
substance acceptable to the Issuing Lender (in the exercise of its Permitted Discretion), including
the requirement that the amounts payable thereunder must be payable in Dollars. If Issuing Lender
is obligated to advance funds under a Letter of Credit, Borrowers immediately shall reimburse such
L/C Disbursement to Issuing Lender by paying to Agent an amount equal to such L/C Disbursement not
later than 2:00 p.m., Georgia time, on the date that such L/C Disbursement is made, if
Administrative Borrower shall have received written or telephonic notice of such L/C Disbursement
prior to 1:00 p.m., Georgia time, on such date, or, if such notice has not been received by
Administrative Borrower prior to such time on such date, then not later than 2:00 p.m., Georgia
time, on the Business Day that Administrative Borrower receives such notice, if such notice is
received prior to 1:00 p.m., Georgia time, on the date of receipt, and, in the absence of such
reimbursement, the L/C Disbursement immediately and automatically shall be deemed to be an Advance
hereunder and, initially, shall bear interest at the rate then applicable to Advances that are Base
Rate Loans. To the extent an L/C Disbursement is deemed to be an Advance hereunder, Borrowers’
obligation to reimburse such L/C Disbursement shall be discharged and replaced by the resulting
Advance. Promptly following receipt by Agent of any payment from Borrowers pursuant to this
paragraph, Agent shall distribute such payment to the Issuing Lender or, to the extent that Lenders
have made payments pursuant to Section 2.12(b) to reimburse the Issuing Lender, then to
such Lenders and the Issuing Lender as their interests may appear.

- 18 -

 

          (b) Promptly following receipt of a notice of L/C Disbursement pursuant to
Section 2.12(a), each Lender with a Revolver Commitment agrees to fund its Pro Rata Share
of any Advance deemed made pursuant to the foregoing subsection on the same terms and conditions as
if Borrowers had requested such Advance and Agent shall promptly pay to Issuing Lender the amounts
so received by it from the Lenders. By the issuance of a Letter of Credit (or an amendment to a
Letter of Credit increasing the amount thereof) and without any further action on the part of the
Issuing Lender or the Lenders with Revolver Commitments, the Issuing Lender shall be deemed to have
granted to each Lender with a Revolver Commitment, and each Lender with a Revolver Commitment shall
be deemed to have purchased, a participation in each Letter of Credit, in an amount equal to its
Pro Rata Share of the Risk Participation Liability of such Letter of Credit, and each such Lender
agrees to pay to Agent, for the account of the Issuing Lender, such Lender’s Pro Rata Share of any
payments made by the Issuing Lender under such Letter of Credit. In consideration and in
furtherance of the foregoing, each Lender with a Revolver Commitment hereby absolutely and
unconditionally agrees to pay to Agent, for the account of the Issuing Lender, such Lender’s Pro
Rata Share of each L/C Disbursement made by the Issuing Lender and not reimbursed by Borrowers on
the date due as provided in Section 2.12(a), or of any reimbursement payment required to be
refunded to Borrowers for any reason. Each Lender with a Revolver Commitment acknowledges and
agrees that its obligation to deliver to Agent, for the account of the Issuing Lender, an amount
equal to its respective Pro Rata Share of each L/C Disbursement made by the Issuing Lender pursuant
to this Section 2.12(b) shall be absolute and unconditional and such remittance shall be
made notwithstanding the occurrence or continuation of an Event of Default or Default or the
failure to satisfy any condition set forth in Section 3. If any such Lender fails to make
available to Agent the amount of such Lender’s Pro Rata Share of each L/C Disbursement made by the
Issuing Lender in respect of such Letter of Credit as provided in this Section, such Lender shall
be deemed to be a Defaulting Lender and Agent (for the account of the Issuing Lender) shall be
entitled to recover such amount on demand from such Lender together with interest thereon at the
Defaulting Lender Rate until paid in full.

          (c) Each Borrower hereby agrees to indemnify, save, defend, and hold the Lender Group harmless
from any loss, cost, expense, or liability, and reasonable attorneys fees incurred by the Lender
Group arising out of or in connection with any Letter of Credit; provided, however,
that no Borrower shall be obligated hereunder to indemnify for any loss, cost, expense, or
liability to the extent that it is caused by the gross negligence or willful misconduct of the
Issuing Lender or any other member of the Lender Group. Each Borrower agrees to be bound by the
Underlying Issuer’s regulations and interpretations of any Underlying Letter of Credit or by
Issuing Lender’s interpretations of any L/C issued by Issuing Lender to or for such Borrower’s
account, even though this interpretation may be different from such Borrower’s own, and each
Borrower understands and agrees that the Lender Group shall not be liable for any error,
negligence, or mistake, whether of omission or commission, in following Borrowers’ instructions or
those contained in the Letter of Credit or any modifications, amendments, or supplements thereto.
Each Borrower understands that the L/C Undertakings may require Issuing Lender to indemnify the
Underlying Issuer for certain costs or liabilities arising out of claims by Borrowers against such
Underlying Issuer. Each Borrower hereby agrees to indemnify, save, defend, and hold the Lender
Group harmless with respect to any loss, cost, expense (including reasonable attorneys fees), or
liability incurred by the Lender Group under any L/C Undertaking as a result of the Lender Group’s
indemnification of any Underlying Issuer; provided, however, that no Borrower shall
be obligated hereunder to indemnify for any loss, cost, expense, or liability to the extent that it
is caused by the gross negligence or willful misconduct of the Issuing Lender or any other member
of the Lender Group. Each Borrower hereby acknowledges and agrees that neither the Lender Group
nor the Issuing Lender shall be responsible for delays, errors, or omissions resulting from the
malfunction of equipment in connection with any Letter of Credit.

          (d) Each Borrower hereby authorizes and directs any Underlying Issuer to deliver to the
Issuing Lender all instruments, documents, and other writings and property received by such

- 19 -

 

Underlying Issuer pursuant to such Underlying Letter of Credit and to accept and rely upon the
Issuing Lender’s instructions with respect to all matters arising in connection with such
Underlying Letter of Credit and the related application.

          (e) Any and all issuance charges, commissions, fees, and costs incurred by the Issuing Lender
relating to Underlying Letters of Credit shall be Lender Group Expenses for purposes of this
Agreement and immediately shall be reimbursable by Borrower to Agent for the account of the Issuing
Lender; it being acknowledged and agreed by Borrowers that, as of the Closing Date, the issuance
charge imposed by the prospective Underlying Issuer is 0.825% per annum times the undrawn amount of
each Underlying Letter of Credit, that such issuance charge may be changed from time to time, and
that the Underlying Issuer also imposes a schedule of charges for amendments, extensions, drawings,
and renewals.

          (f) If by reason of (i) any change after the Closing Date in any applicable law, treaty, rule,
or regulation or any change in the interpretation or application thereof by any Governmental
Authority, or (ii) compliance by the Underlying Issuer or the Lender Group with any direction,
request, or requirement (irrespective of whether having the force of law) of any Governmental
Authority or monetary authority including, Regulation D of the Federal Reserve Board as from time
to time in effect (and any successor thereto):

               (i) any reserve, deposit, or similar requirement is or shall be imposed or modified in respect
of any Letter of Credit issued hereunder, or

               (ii) there shall be imposed on the Underlying Issuer or the Lender Group any other condition
regarding any Underlying Letter of Credit or any Letter of Credit issued pursuant hereto,

and the result of the foregoing is to increase, directly or indirectly, the cost to the Lender
Group of issuing, making, guaranteeing, or maintaining any Letter of Credit or to reduce the amount
receivable in respect thereof by the Lender Group, then, and in any such case, Agent may, at any
time within a reasonable period after the additional cost is incurred or the amount received is
reduced, notify Administrative Borrower, and Borrowers shall pay on demand such amounts as Agent
may specify to be necessary to compensate the Lender Group for such additional cost or reduced
receipt, together with interest on such amount from the date of such demand until payment in full
thereof at the rate then applicable to Base Rate Loans hereunder. The determination by Agent of
any amount due pursuant to this Section, as set forth in a certificate setting forth the
calculation thereof in reasonable detail, shall, in the absence of manifest or demonstrable error,
be final and conclusive and binding on all of the parties hereto.

     2.13 LIBOR Option.

          (a) Interest and Interest Payment Dates. Interest and Interest Payment Dates. In lieu of
having interest on any Advance charged at a rate based upon the Base Rate, Borrowers shall have the
option (the “LIBOR Option”) to have interest on all or a portion of the Advances or the
Term Loan be charged (whether at the time when made (unless otherwise provided herein), upon
conversion from a Base Rate Loan to a LIBOR Rate Loan, or upon continuation of a LIBOR Rate Loan as
a LIBOR Rate Loan) at a rate of interest based upon the LIBOR Rate. Interest on LIBOR Rate Loans
shall be payable on the earliest of (i) the last day of the Interest Period applicable thereto,
(provided, however, that, subject to the following clauses (ii) and (iii), in the
case of any Interest Period greater than 3 months in duration, interest shall be payable at 3 month
intervals after the commencement of the applicable Interest Period and on the last day of such
Interest Period), (ii) the date on which all or any portion of the Obligations are accelerated
pursuant to the terms hereof, or (iii) the date on which this
Agreement is

- 20 -

 

terminated pursuant to the terms hereof. On the last day of each applicable
Interest Period, unless Administrative Borrower properly has exercised the LIBOR Option with
respect thereto, the interest rate applicable to such LIBOR Rate Loan automatically shall convert
to the rate of interest then applicable to Base Rate Loans of the same type hereunder. At any time
that an Event of Default has occurred and is continuing, Borrowers no longer shall have the option
to request that Advances bear interest at a rate based upon the LIBOR Rate and Agent shall have the
right to convert the interest rate on all outstanding LIBOR Rate Loans (other than Term Loan) to
the rate then applicable to Base Rate Loans hereunder.

          (b) LIBOR Election.

               (i) Administrative Borrower may, at any time and from time to time, so long as no Event of
Default has occurred and is continuing, elect to exercise the LIBOR Option by notifying Agent prior
to 2:00 p.m. (Georgia time) at least 3 Business Days prior to the commencement of the proposed
Interest Period (the “LIBOR Deadline”). Notice of Administrative Borrower’s election of
the LIBOR Option for a permitted portion of the Advances or the Term Loan and an Interest Period
pursuant to this Section shall be made by delivery to Agent of a LIBOR Notice received by Agent
before the LIBOR Deadline, or by telephonic notice received by Agent before the LIBOR Deadline (to
be confirmed by delivery to Agent of a LIBOR Notice received by Agent prior to 5:00 p.m. (Georgia
time) on the same day). Promptly upon its receipt of each such LIBOR Notice, Agent shall provide a
copy thereof to each of the affected Lenders.

               (ii) Each LIBOR Notice shall be irrevocable and binding on Borrowers. In connection with each
LIBOR Rate Loan, each Borrower shall indemnify, defend, and hold Agent and the Lenders harmless
against any loss, cost, or expense incurred by Agent or any Lender as a result of (A) the payment
of any principal of any LIBOR Rate Loan other than on the last day of an Interest Period applicable
thereto (including as a result of an Event of Default), (B) the conversion of any LIBOR Rate Loan
other than on the last day of the Interest Period applicable thereto, or (C) the failure to borrow,
convert, continue or prepay any LIBOR Rate Loan on the date specified in any LIBOR Notice delivered
pursuant hereto (such losses, costs, or expenses, “Funding Losses”). Funding Losses shall,
with respect to Agent or any Lender, be deemed to equal the amount determined by Agent or such
Lender to be the excess, if any, of (1) the amount of interest that would have accrued on the
principal amount of such LIBOR Rate Loan had such event not occurred, at the LIBOR Rate that would
have been applicable thereto, for the period from the date of such event to the last day of the
then current Interest Period therefor (or, in the case of a failure to borrow, convert, or
continue, for the period that would have been the Interest Period therefor), minus (2) the amount
of interest that would accrue on such principal amount for such period at the interest rate which
Agent or such Lender would be offered were it to be offered, at the commencement of such period,
Dollar deposits of a comparable amount and period in the London interbank market. A certificate of
Agent or a Lender delivered to Administrative Borrower setting forth any amount or amounts that
Agent or such Lender is entitled to receive pursuant to this Section 2.13 shall be
conclusive absent manifest error.

               (iii) Borrowers shall have not more than 7 LIBOR Rate Loans in effect at any given time, of
which no more than one LIBOR Rate Loan may be the Term Loan. Borrowers only may exercise the LIBOR
Option for LIBOR Rate Loans of at least $1,000,000 and integral multiples of $500,000 in
excess thereof.

          (c) Conversion. Borrowers may convert LIBOR Rate Loans (other than Term Loan) to Base Rate
Loans at any time; provided, however, that in the event that LIBOR Rate Loans are
converted or prepaid on any date that is not the last day of the Interest Period applicable
thereto, including as a result of any automatic prepayment through the required application by
Agent of proceeds of Parent’s
and its Subsidiaries’ Collections in accordance with Section 2.4(b) or for any other
reason, including early

- 21 -

 

termination of the term of this Agreement or acceleration of all or any
portion of the Obligations pursuant to the terms hereof, each Borrower shall indemnify, defend, and
hold Agent and the Lenders and their Participants harmless against any and all Funding Losses in
accordance with Section 2.13 (b)(ii) above.

          (d) Special Provisions Applicable to LIBOR Rate.

               (i) The LIBOR Rate may be adjusted by Agent with respect to any Lender on a prospective basis
to take into account any additional or increased costs to such Lender of maintaining or obtaining
any eurodollar deposits or increased costs, in each case, due to changes in applicable law
occurring subsequent to the commencement of the then applicable Interest Period, including changes
in tax laws (except changes of general applicability in corporate income tax laws) and changes in
the reserve requirements imposed by the Board of Governors of the Federal Reserve System (or any
successor), excluding the Reserve Percentage, which additional or increased costs would increase
the cost of funding or maintaining loans bearing interest at the LIBOR Rate. In any such event,
the affected Lender shall give Administrative Borrower and Agent notice of such a determination and
adjustment and Agent promptly shall transmit the notice to each other Lender and, upon its receipt
of the notice from the affected Lender, Administrative Borrower may, by notice to such affected
Lender (x) require such Lender to furnish to Administrative Borrower a statement setting forth the
basis for adjusting such LIBOR Rate and the method for determining the amount of such adjustment,
or (y) repay the LIBOR Rate Loans with respect to which such adjustment is made (together with any
amounts due under this Section 2.13(d)(i). Failure or delay on the part of any Lender to
demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s right
to demand such compensation; provided that Borrowers shall not be required to compensate a
Lender pursuant to this Section for any additional or increased costs incurred more than 360 days
prior to the date that such Lender notifies the Administrative Borrower of such law giving rise to
such additional or increased costs and of such Lender’s intention to claim compensation therefor;
provided further that if such claim arises by reason of the adoption of or change
in any law that is retroactive, then the 360-day period referred to above shall be extended to
include the period of retroactive effect thereof.

               (ii) In the event that any change in market conditions or any law, regulation, treaty, or
directive, or any change therein or in the interpretation of application thereof, shall at any time
after the date hereof, in the reasonable opinion of any Lender, make it unlawful or impractical for
such Lender to fund or maintain LIBOR Rate Loans or to continue such funding or maintaining, or to
determine or charge interest rates at the LIBOR Rate, such Lender shall give notice of such changed
circumstances to Agent and Administrative Borrower and Agent promptly shall transmit the notice to
each other Lender and (y) in the case of any LIBOR Rate Loans of such Lender that are outstanding,
the date specified in such Lender’s notice shall be deemed to be the last day of the Interest
Period of such LIBOR Rate Loans, and interest upon the LIBOR Rate Loans of such Lender thereafter
shall accrue interest at the rate then applicable to Base Rate Loans, and (z) Borrowers shall not
be entitled to elect the LIBOR Option until such Lender determines that it would no longer be
unlawful or impractical to do so.

          (e) No Requirement of Matched Funding. Anything to the contrary contained herein
notwithstanding, neither Agent, nor any Lender, nor any of their Participants, is required actually
to acquire eurodollar deposits to fund or otherwise match fund any Obligation as to which interest
accrues at the LIBOR Rate. The provisions of this Section shall apply as if each Lender or its
Participants had match funded any Obligation as to which interest is accruing at the LIBOR Rate by
acquiring eurodollar deposits for each Interest Period in the amount of the LIBOR Rate Loans.

     2.14 Capital Requirements. If, after the date hereof, any Lender determines that (i)
the adoption of or change in any law, rule, regulation or guideline regarding capital requirements
for banks or
bank holding companies, or any change in the interpretation or application thereof by any
Governmental

- 22 -

 

Authority charged with the administration thereof, or (ii) compliance by such Lender
or its parent bank holding company with any guideline, request, or directive of any such entity
regarding capital adequacy (whether or not having the force of law), has the effect of reducing the
return on such Lender’s or such holding company’s capital as a consequence of such Lender’s
Commitments hereunder to a level below that which such Lender or such holding company could have
achieved but for such adoption, change, or compliance (taking into consideration such Lender’s or
such holding company’s then existing policies with respect to capital adequacy and assuming the
full utilization of such entity’s capital) by any amount deemed by such Lender to be material, then
such Lender may notify Administrative Borrower and Agent thereof. Following receipt of such
notice, Borrowers agree to pay such Lender on demand the amount of such reduction of return of
capital as and when such reduction is determined, payable within 90 days after presentation by such
Lender of a statement in the amount and setting forth in reasonable detail such Lender’s
calculation thereof and the assumptions upon which such calculation was based (which statement
shall be deemed true and correct absent manifest error). In determining such amount, such Lender
may use any reasonable averaging and attribution methods. Failure or delay on the part of any
Lender to demand compensation pursuant to this Section shall not constitute a waiver of such
Lender’s right to demand such compensation; provided that Borrowers shall not be required to
compensate a Lender pursuant to this Section for any reduction in return incurred more than 360
days prior to the date that such Lender notifies the Administrative Borrower of such law, rule,
regulation or guideline giving rise to such reductions and of such Lender’s intention to claim
compensation therefor; provided further that if such claim arises by reason of the adoption of or
change in any law, rule, regulation or guideline that is retroactive, then the 360-day period
referred to above shall be extended to include the period of retroactive effect thereof.

     2.15 Tax Reporting. (a) Borrowers and the Lenders agree (i) to treat the Term Loans
as debt for all United States tax purposes, (ii) to treat the issue price of the Term Loans (within
the meaning of Section 1273 of the IRC) as being equal to the aggregate original principal amount
of the Term Loans, (iii) to treat the Term Loans as issued with original issue discount (“OID”),
(iv) that any calculation by Borrowers regarding the amount of OID for any accrual period on the
Term Loans shall be subject to review and approval of the Required Lenders (such approval not to be
unreasonably withheld, delayed or conditioned), and (v) to adhere to this Agreement for tax
purposes and not to take any action (including in communication with any taxing authority) or file
any tax return, report or declaration inconsistent with any of the agreed provisions of this
Section 2.15 (including with respect to the issue price of the Term Loans set forth in the
preceding clause (ii) and the amount of OID on the Term Loans as determined in accordance with the
preceding clause (iv)). The inclusion of this Section 2.15 is not an admission by any
Lender that it is subject to United States taxation.

          (b) Borrowers and the Lenders, having adverse interests and as a result of arms-length
bargaining, agree that (i) neither Lenders nor any of their officers, directors, representatives,
partners, members or employees have rendered or have agreed to render any services to Borrowers in
connection with this Agreement or the making of the Term Loans; (ii) the Warrant is not being
issued as compensation; and (iii) for the purposes and within the meaning of Section 1273(c)(2) of
the IRC the issue price of the Warrant is $2,280,602, which is its fair market value. Borrowers
and the Lenders acknowledge that this allocation is based on the relative fair market value of the
Warrant. For federal, state and local tax purposes, Borrowers and the Lender agree to take
reporting and other positions with respect to the Warrant which are consistent with the purchase
price of the Warrant set forth herein.

     2.16 Joint and Several Liability of Borrowers.

          (a) Each Borrower is accepting joint and several liability hereunder and under the other Loan
Documents in consideration of the financial accommodations to be provided by the Lender
Group under this Agreement, for the mutual benefit, directly and indirectly, of each Borrower
and in

- 23 -

 

consideration of the undertakings of the other Borrowers to accept joint and several
liability for the Obligations.

          (b) Each Borrower, jointly and severally, hereby irrevocably and unconditionally accepts, not
merely as a surety but also as a co-debtor, joint and several liability with the other Borrowers,
with respect to the payment and performance of all of the Obligations (including any Obligations
arising under this Section 2.16), it being the intention of the parties hereto that all the
Obligations shall be the joint and several obligations of each Borrower without preferences or
distinction among them.

          (c) If and to the extent that any Borrower shall fail to make any payment with respect to any
of the Obligations as and when due or to perform any of the Obligations in accordance with the
terms thereof, then in each such event the other Borrowers will make such payment with respect to,
or perform, such Obligation.

          (d) The Obligations of each Borrower under the provisions of this Section 2.16
constitute the absolute and unconditional, full recourse Obligations of each Borrower enforceable
against each Borrower to the full extent of its properties and assets, irrespective of the
validity, regularity or enforceability of this Agreement or any other circumstances whatsoever,
subject to applicable law.

          (e) Except as otherwise expressly provided in this Agreement, each Borrower hereby waives
notice of acceptance of its joint and several liability, notice of any Advances or Letters of
Credit issued under or pursuant to this Agreement, notice of the occurrence of any Default, Event
of Default, or of any demand for any payment under this Agreement, notice of any action at any time
taken or omitted by Agent or Lenders under or in respect of any of the Obligations, any requirement
of diligence or to mitigate damages and, generally, to the extent permitted by applicable law, all
demands, notices and other formalities of every kind in connection with this Agreement (except as
otherwise provided in this Agreement). Each Borrower hereby assents to, and waives notice of, any
extension or postponement of the time for the payment of any of the Obligations, the acceptance of
any payment of any of the Obligations, the acceptance of any partial payment thereon, any waiver,
consent or other action or acquiescence by Agent or Lenders at any time or times in respect of any
default by any Borrower in the performance or satisfaction of any term, covenant, condition or
provision of this Agreement, any and all other indulgences whatsoever by Agent or Lenders in
respect of any of the Obligations, and the taking, addition, substitution or release, in whole or
in part, at any time or times, of any security for any of the Obligations or the addition,
substitution or release, in whole or in part, of any Borrower. Without limiting the generality of
the foregoing, each Borrower assents to any other action or delay in acting or failure to act on
the part of any Agent or Lender with respect to the failure by any Borrower to comply with any of
its respective Obligations, including, without limitation, any failure strictly or diligently to
assert any right or to pursue any remedy or to comply fully with applicable laws or regulations
thereunder, which might, but for the provisions of this Section 2.16 afford grounds for
terminating, discharging or relieving any Borrower, in whole or in part, from any of its
Obligations under this Section 2.16, it being the intention of each Borrower that, so long
as any of the Obligations hereunder remain unsatisfied, the Obligations of each Borrower under this
Section 2.16 shall not be discharged except by performance and then only to the extent of
such performance. The Obligations of each Borrower under this Section 2.16 shall not be
diminished or rendered unenforceable by any winding up, reorganization, arrangement, liquidation,
reconstruction or similar proceeding with respect to any Borrower or any Agent or Lender.

          (f) Each Borrower represents and warrants to Agent and Lenders that such Borrower is currently
informed of the financial condition of Borrowers and of all other circumstances which a diligent
inquiry would reveal and which bear upon the risk of nonpayment of the Obligations. Each Borrower
further represents and warrants to Agent and Lenders that such Borrower has read and
understands the terms and conditions of the Loan Documents. Each Borrower hereby covenants
that such

- 24 -

 

Borrower will continue to keep informed of Borrowers’ financial condition, the financial
condition of other guarantors, if any, and of all other circumstances which bear upon the risk of
nonpayment or nonperformance of the Obligations.

          (g) Each Borrower waives all rights and defenses arising out of an election of remedies by
Agent or any Lender, even though that election of remedies, such as a nonjudicial foreclosure with
respect to security for a guaranteed obligation, has destroyed Agent’s or such Lender’s rights of
subrogation and reimbursement against such Borrower by the operation of Section 580(d) of the
California Code of Civil Procedure or otherwise.

          (h) Each Borrower waives all rights and defenses that such Borrower may have because the
Obligations are secured by Real Property. This means, among other things:

               (i) Agent and Lenders may collect from such Borrower without first foreclosing on any Real or
Personal Property Collateral pledged by Borrowers.

               (ii) If Agent or any Lender forecloses on any Real Property Collateral pledged by Borrowers:

                    (A) Subject to applicable law, the amount of the Obligations may be reduced only by the price
for which that collateral is sold at the foreclosure sale, even if the collateral is worth more
than the sale price.

                    (B) Agent and Lenders may collect from such Borrower even if Agent or Lenders, by foreclosing
on the Real Property Collateral, has destroyed any right such Borrower may have to collect from the
other Borrowers.

Subject to applicable law, this is an unconditional and irrevocable waiver of any rights and
defenses such Borrower may have because the Obligations are secured by Real Property. These rights
and defenses include, but are not limited to, any rights or defenses based upon Section 580a, 580b,
580d or 726 of the California Code of Civil Procedure.

          (i) The provisions of this Section 2.16 are made for the benefit of Agent, Lenders and
their respective successors and assigns, and may be enforced by it or them from time to time
against any or all Borrowers as often as occasion therefor may arise and without requirement on the
part of Agent, Lender, successor or assign first to marshal any of its or their claims or to
exercise any of its or their rights against any Borrower or to exhaust any remedies available to it
or them against any Borrower or to resort to any other source or means of obtaining payment of any
of the Obligations hereunder or to elect any other remedy. The provisions of this Section
2.16 shall remain in effect until all of the Obligations shall have been paid in full or
otherwise fully satisfied. If at any time, any payment, or any part thereof, made in respect of
any of the Obligations, is rescinded or must otherwise be restored or returned by Agent or any
Lender upon the insolvency, bankruptcy or reorganization of any Borrower, or otherwise, the
provisions of this Section 2.16 will forthwith be reinstated in effect, as though such
payment had not been made.

          (j) Until the Obligations have been paid in full and all of the Commitments terminated, each
Borrower hereby agrees that it will not enforce any of its rights of contribution or subrogation
against any other Borrower with respect to any liability incurred by it hereunder or under any of
the other Loan Documents, any payments made by it to Agent or Lenders with respect to any of the
Obligations or any collateral security therefor until such time as all of the Obligations have been
paid in
full in cash. Any claim which any Borrower may have against any other Borrower with respect
to any

- 25 -

 

payments to any Agent or Lender hereunder or under any other Loan Documents are hereby
expressly made subordinate and junior in right of payment, without limitation as to any increases
in the Obligations arising hereunder or thereunder, to the prior payment in full in cash of the
Obligations and, in the event of any insolvency, bankruptcy, receivership, liquidation,
reorganization or other similar proceeding under the laws of any jurisdiction relating to any
Borrower, its debts or its assets, whether voluntary or involuntary, all such Obligations shall be
paid in full in cash before any payment or distribution of any character, whether in cash,
securities or other property, shall be made to any other Borrower therefor.

          (k) Each Borrower hereby agrees that, after the occurrence and during the continuance of any
Default or Event of Default, the payment of any amounts due with respect to the indebtedness owing
by any Borrower to any other Borrower is hereby subordinated to the prior payment in full in cash
of the Obligations. Each Borrower hereby agrees that after the occurrence and during the
continuance of any Default or Event of Default, such Borrower will not demand, sue for or otherwise
attempt to collect any indebtedness of any other Borrower owing to such Borrower until the
Obligations shall have been paid in full in cash. If, notwithstanding the foregoing sentence, such
Borrower shall collect, enforce or receive any amounts in respect of such indebtedness, such
amounts shall be collected, enforced and received by such Borrower as trustee for Agent, and such
Borrower shall deliver any such amounts to Agent for application to the Obligations in accordance
with Section 2.4(b).

3. CONDITIONS; TERM OF AGREEMENT.

     3.1 Conditions Precedent to the Initial Extension of Credit. The obligation of each Lender
to make its initial extensions of credit provided for hereunder, is subject to the fulfillment, to
the satisfaction of Agent and each Lender of each of the conditions precedent set forth on
Schedule 3.1 (the making of such initial extension of credit by a Lender being conclusively
deemed to be its satisfaction or waiver of the conditions precedent ).

     3.2 Conditions Precedent to all Extensions of Credit. The obligation of the Lender Group
(or any member thereof) to initially make the Term Loan, any Closing Date Advance and thereafter
any future Advances hereunder (or to extend any other credit hereunder) at any time shall be
subject to the following conditions precedent:

          (a) the representations and warranties of Parent or its Subsidiaries contained in this
Agreement or in the other Loan Documents or other certificate delivered to the Agent or any Lender
pursuant hereto or thereto shall be true and correct in all respects on and as of the date of such
extension of credit, as though made on and as of such date (except to the extent that such
representations and warranties relate solely to an earlier date);

          (b) no Default or Event of Default shall have occurred and be continuing on the date of such
extension of credit, nor shall either result from the making thereof;

          (c) no injunction, writ, restraining order, or other order of any nature restricting or
prohibiting, directly or indirectly, the extending of such credit shall have been issued and remain
in force by any Governmental Authority against any Borrower, Agent, or any Lender; and

          (d) no Material Adverse Change shall have occurred since December 31, 2006.

     3.3 Term. This Agreement shall continue in full force and effect for a term ending on
December 13, 2012 (the “Maturity Date”). The foregoing notwithstanding, the Lender Group,
upon the
election of the Required Lenders, shall have the right to terminate its obligations under this
Agreement immediately and without notice upon the occurrence and during the continuation of an
Event of Default.

- 26 -

 

     3.4 Effect of Termination. On the date of termination of this Agreement, all Obligations
(including contingent reimbursement obligations of Borrowers with respect to outstanding Letters of
Credit and including all Bank Product Obligations) immediately shall become due and payable without
notice or demand (including the requirement that Borrower provide (a) Letter of Credit
Collateralization, and (b) Bank Product Collateralization). No termination of this Agreement,
however, shall relieve or discharge Parent or its Subsidiaries of their duties, Obligations, or
covenants hereunder or under any other Loan Document and Agent’s Liens in the Collateral shall
remain in effect until all Obligations have been paid in full and the Lender Group’s obligations to
provide additional credit hereunder have been terminated. When this Agreement has been terminated
and all of the Obligations have been paid in full and the Lender Group’s obligations to provide
additional credit under the Loan Documents have been terminated irrevocably, Agent will, at
Borrowers’ sole expense, without recourse, representation or warranty, execute and deliver any
termination statements, lien releases, mortgage releases, re-assignments of trademarks, discharges
of security interests, and other similar discharge or release documents (and, if applicable, in
recordable form) as are reasonably necessary to release, as of record, Agent’s Liens and all
notices of security interests and liens previously filed by Agent with respect to the Obligations.

     3.5 Early Termination by Borrowers. Borrowers have the option, at any time upon 10 days
prior written notice to Agent, to terminate this Agreement and terminate the Commitments hereunder
by paying to Agent, in cash, the Obligations (including (a) providing Letter of Credit
Collateralization with respect to the then existing Letter of Credit Usage and (b) providing Bank
Product Collateralization with respect to the then existing Bank Products), in full. If Borrowers
have sent a notice of termination pursuant to the provisions of this Section, then the Commitments
shall terminate and Borrowers shall be obligated to repay the Obligations (including (a) providing
Letter of Credit Collateralization with respect to the then existing Letter of Credit Usage and (b)
providing Bank Product Collateralization with respect to the then existing Bank Products), in full
on the date set forth as the date of termination of this Agreement in such notice.

4. REPRESENTATIONS AND WARRANTIES.

          In order to induce the Lender Group to enter into this Agreement, each Borrower makes the
following representations and warranties with respect to itself and its property to the Lender
Group which shall be true, correct, and complete, in all respects, as of the date hereof, and at
and as of the date of the making of each Advance (or other extension of credit) made thereafter, as
though made on and as of the date of such Advance (or other extension of credit) (except to the
extent that such representations and warranties relate solely to an earlier date which shall have
been true, correct and complete as of such earlier date) and such representations and warranties
shall survive the execution and delivery of this Agreement:

     4.1 No Encumbrances. Schedule 4.1 sets forth all Real Property (other than Oil and
Gas Properties) owned, leased, subleased or used by Parent or any of its Subsidiaries as of the
Closing Date. Parent and its Subsidiaries have good and defensible title to, or a valid leasehold
interest in, their personal property assets and good and marketable title to, or a valid leasehold
interest in, their Real Property (other than Oil and Gas Properties), in each case, free and clear
of Liens except for Permitted Liens. Schedule 4.1 also describes any purchase options,
rights of first refusal or other similar contractual rights in favor of Parent or any of its
Subsidiaries pertaining to any Real Property (other than Oil and Gas Properties) owned or leased by
Parent or any of its Subsidiaries as of the Closing Date. No portion of any Real Property (other
than Oil and Gas Properties) has suffered any material damage by fire or other casualty loss which
has not heretofore been repaired and restored in all material respects to its original condition or
otherwise remedied. All material permits required to have been issued or appropriate to enable the
Real Property (other than Oil and Gas Properties) to be lawfully occupied and used for all of the
purposes for

- 27 -

 

which they are currently occupied and used have been lawfully issued and are in full
force and effect in all material respects.

     4.2 Margin Stock. Neither Parent nor any of its Subsidiaries is engaged, nor will it
engage, principally or as one of their important activities, in the business of extending credit
for the purpose of “purchasing” or “carrying” any “margin security” as such terms are defined in
Regulation U of the Federal Reserve Board as now and from time to time hereafter in effect (such
securities being referred to herein as “Margin Stock”). Neither Parent nor any of its Subsidiaries
owns any Margin Stock, and none of the proceeds of the Term Loan, Advances or other extensions of
credit under this Agreement will be used, directly or indirectly, for the purpose of purchasing or
carrying any Margin Stock, for the purpose of reducing or retiring any Indebtedness which was
originally incurred to purchase or carry any Margin Stock or for any other purpose which might
cause any of the Term Loan, Advances or other extensions of credit under this Agreement to be
considered a “purpose credit” within the meaning of Regulation T, U or X of the Federal Reserve
Board.

     4.3 Brokers. No broker or finder acting on behalf of any Borrower brought about the
obtaining, making or closing of the Loans and no Borrower has any obligation to any Person in
respect of any finder’s or brokerage fees in connection therewith, other than those fees owing to
Rivington Capital Advisors, LLC and SMH Capital Inc. and previously disclosed to the Lenders.

     4.4 Jurisdiction of Organization; Location of Chief Executive Office; Organizational
Identification Number; Commercial Tort Claims.

cancellation or termination has been received with respect to any such policy. Schedule

are valid, outstanding and enforceable policies; provide adequate coverage in at least such amounts
and against at least such risks (but including in any event public liability) as are required by

companies engaged in the same or a similar business for the assets and operations of Parent and its
Subsidiaries; will remain in full force and effect through the respective dates set forth in

     4.22 Taxes. All federal, state and other material tax returns, reports and statements,
including information returns, required by any Governmental Authority to be filed by Parent and its
Subsidiaries have been filed with the appropriate Governmental Authority (and all such returns,

withheld by Parent and its Subsidiaries from its respective employees for all periods in full and
complete compliance with all applicable federal, state, local and foreign law and such withholdings

as of the Closing Date those taxable years for which Parent’s and its Subsidiaries’ tax returns are
currently being audited by the IRS or any other applicable Governmental Authority and any
assessments or threatened assessments in connection with such audit, or otherwise currently
outstanding. As of the Closing Date and except as set forth on Schedule 4.22, there is no
action, suit, proceeding, investigation, audit or claim now pending or threatened by any authority
regarding any taxes relating to Parent or its Subsidiaries, which, either individually or in the
aggregate, could reasonably be expected to cause a Material Adverse Change or to result in a
material liability to Parent or its Subsidiaries. Except as described on Schedule 4.22,
neither Parent nor any of its Subsidiaries has executed or filed with the IRS or any other
Governmental Authority any agreement or other document extending, or having the effect of
extending, the period for assessment or collection of any charges or other amounts. None of Parent
or its Subsidiaries and their respective predecessors are liable for any charges or other amounts:
(a) under any agreement (including any tax sharing agreements) or (b) to Parent’s or its
Subsidiaries’ knowledge, as a transferee. As of the Closing Date, neither Parent nor its

- 35 -

 

Subsidiaries has agreed or been requested to make any adjustment under IRC Section 481(a), by
reason of a change in accounting method or otherwise, which could cause a Material Adverse Change.

Schedule 4.23 or on the most recent certificate delivered pursuant to Section
5.20(c), on a net basis there are no gas imbalances, take-or-pay or other similar arrangement
or any prepayment with respect to any of the Oil and Gas Properties that would require Parent or
any of its Subsidiaries either to make cash settlements for such production or to deliver
Hydrocarbons produced from the Oil and Gas Properties at some future time in any case without then
or thereafter receiving full payment therefor exceeding, during any monthly period, two percent
(2%) of the current aggregate monthly gas production for such monthly period from the Oil and Gas
Properties of Parent and its Subsidiaries.

     4.24 Swap Agreements. Schedule 4.24 sets forth, as of the Closing Date, a true and
complete list of all Swap Agreements (including any commodity price swap agreements, forward

Hydrocarbons or other commodities) of Borrowers, the material terms thereof (including the type,
term, effective date, termination date and notional amounts or volumes), all credit support
agreements relating thereto (including any margin required or supplied), and the counterparty to
each such agreement.

     4.25 Location of Real Property and Leased Premises.

Gas Properties that are Real Property whether leased or owned by Parent (and its Subsidiaries, as
applicable) and the respective addresses (if any), counties and states thereof.

          (b) Parent and each of its Subsidiaries have good and defensible title to all of their Oil
and Gas Properties set forth on Schedule 4.25 which constitute Real Property and good and
defensible title to all of their Oil and Gas Properties which constitute personal property,
except for (i) such imperfections of title which do not in the aggregate materially detract from
the value thereof to, or the use thereof in, the business of Borrowers or (ii) Permitted Liens.
The quantum and nature of the interest of Parent and its Subsidiaries in and to the Oil and Gas
Properties as set forth in the Initial Reserve Report or the most recent Reserve Report, as the
case may be, includes the entire interest of Parent and its Subsidiaries in such Oil and Gas
Properties as of the date of the Initial Reserve Report (subject, in the case of the Lower Rio
Del formation acreage, to the Farmout Agreement) or such applicable Reserve Report delivered by
Administrative Borrower to Agent pursuant to Section 5.20, as the case may be, and are
complete and accurate in all material respects as of the date of the Initial Reserve Report or
such applicable Reserve Report, as the case may be; and there are no “back-in” or “reversionary”
interests held by third parties which could materially reduce the interest of any Borrower in
such Oil and Gas Properties except as expressly set forth in the Initial Reserve Report or the
most recent Reserve Report, as the case may be. The ownership of the Oil and Gas Properties by
Parent and each of its Subsidiaries shall not in any material respect obligate Parent or any such
Subsidiary to bear the costs and expenses relating to the maintenance, development or operations
of each such Oil and Gas Property in an amount in excess of the working interest of record of
Borrowers in each Oil and Gas Property set forth in the Initial Reserve Report or the most recent
Reserve Report, as the case may be, other than with respect to the ORRI Conveyance pursuant to
which Foothills Texas, Inc. retains responsibility for costs and expenses associated with
maintenance, development and operations of the Oil and Gas Properties covered by such agreement
as set forth therein.

          (c) For current volumes of production of Hydrocarbons from the Oil and Gas Properties of
Parent and its Subsidiaries, Parent and each of its Subsidiaries’ marketing, gathering,
transportation, processing and treating facilities and equipment, together with any marketing,

- 36 -

 

gathering, transportation, processing and treating contracts in effect between and/or among
Parent, its Subsidiaries and any other Person, are sufficient to gather, transport, process
and/or treat such volumes of production of Hydrocarbons from such Oil and Gas Properties.

          (d) For reasonably anticipated volumes (in excess of current volumes referred to in
clause (c) above) of production of Hydrocarbons from the Oil and Gas Properties of Parent
and its Subsidiaries arising after the Closing Date, Parent and each of its Subsidiaries fully
expect to acquire sufficient marketing, gathering, transportation, processing and treating
facilities and equipment, together with any marketing, gathering, transportation, processing and
treating contracts in effect between and/or among Parent, its Subsidiaries and any other Person
to gather, transport, process and/or treat such reasonably anticipated volumes of production of
Hydrocarbons from the Oil and Gas Properties, and the Projections most recently furnished to
Agent and Lenders reflect the anticipated cost and expense of obtaining and rendering the
foregoing operational.

     4.26 Nature of Business. Neither Parent nor any of its Subsidiaries is engaged in any
business other than the Oil and Gas Business within the continental United States.

     4.27 Seismic Licenses. To the extent not prohibited by the terms thereof, or any
confidentiality agreement, Schedule 4.27 (as amended by Borrowers from time to time)
identifies all of the license agreements relating to the performance of seismic exploration on the
Oil and Gas Properties (“Seismic Licenses”) to which Parent and its Subsidiaries are a party. With
respect to the Seismic Licenses: (i) all Seismic Licenses are in effect and have not expired or
terminated; (ii) neither Parent nor any of its Subsidiaries is in material breach or material
default, and there has occurred no event, fact, or circumstance, that, with the lapse of time or
the giving of notice, or both, would constitute such a material breach or material default by
Parent or any of its Subsidiaries, as applicable, with respect to the terms of any Seismic License;
and (iii) neither Parent, nor any Subsidiary thereof, nor, to the knowledge of Borrowers, any other
party to any Seismic License has given written notice of any action to terminate, cancel, rescind,
or procure a judicial reformation of any Seismic License or any provision thereof. To the extent
not prohibited by the terms of the Seismic Licenses or any confidential agreement, all of the
transfer fees or similar amounts payable by Parent or any of its Subsidiaries, as applicable, under
the terms of the Seismic Licenses upon the consummation of the transactions contemplated herein, or
the method of calculating same, are set forth in Schedule 4.27.

     4.28 Marketing of Production. Except for (i) contracts listed and in effect on the date
hereof on Schedule 4.28, and (ii) contracts thereafter either disclosed in writing to Agent
or included in the most recently delivered Reserve Report and, in any case, approved by Agent (with
respect to all of which contracts Borrowers represent that they or their Subsidiaries are receiving
a price for all production sold thereunder which is computed substantially in accordance with the
terms of the relevant contract and are not having deliveries curtailed substantially below the
subject Property’s delivery capacity), Borrowers have no Long Term Fixed Rate Contracts. As used
herein, “Long Term Fixed Rate Contracts” means any material agreement that is not cancelable on 60
days notice or less without penalty or detriment for the sale of production from Parent’s or its
Subsidiaries’ Hydrocarbons (including, without limitation, calls on or other rights to purchase,
production, whether or not the same are currently being exercised) that (a) pertains to the sale of
production at a fixed price and (b) has a maturity or expiry date of more than six (6) months from
the date of such agreement. Each Borrower (and each of its Subsidiaries) (x) is presently
receiving a price for all production from (or attributable to) each Oil and Gas Property covered by
a production sales contract or marketing contract that is computed in accordance with the terms of
such contract and none of such proceeds are currently being held in suspense by such purchaser or
any other Person and (y) is not having deliveries of production from such Oil and Gas Property
curtailed by any purchaser or transporter of production substantially below such property’s
delivery capacity. Except as set forth in Schedule 4.28, none of the Oil and Gas
Properties of Parent or any Subsidiary thereof) are subject

- 37 -

 

to any contractual or other arrangement whereby payment for production therefrom is to be
deferred for a substantial period of time after the month in which such production is delivered
(i.e., in the case of oil, not in excess of 60 days, and in the case of gas, not in excess of 90
days).

5. AFFIRMATIVE COVENANTS.

          Each Borrower covenants and agrees that, until termination of all of the Commitments and
payment in full of the Obligations, Borrowers shall and shall cause each of their respective
Subsidiaries to do all of the following:

     5.1 Accounting System. Maintain a system of accounting that enables Parent and its
Subsidiaries to produce financial statements in accordance with GAAP and maintain records
pertaining to the Collateral that contain information as from time to time reasonably may be
requested by Agent. Parent and its Subsidiaries also shall keep a reporting system that shows all
additions, sales, claims, returns, and allowances with respect to their and their Subsidiaries’
sales.

     5.2 Collateral Reporting. Provide Agent (and if so requested by Agent, with copies for
each Lender) with each of the reports set forth on Schedule 5.2 at the times specified
therein.

     5.3 Financial Statements, Reports, Certificates. Deliver to Agent, with copies to each
Lender, each of the financial statements, reports, or other items set forth on Schedule 5.3
at the times specified therein. In addition, Parent agrees that no Subsidiary of Parent will have
a fiscal year different from that of Parent.

     5.4 Guarantor Reports. Cause each Guarantor to deliver its annual financial statements at
the time when Parent provides its audited financial statements to Agent, but only to the extent
such Guarantor’s financial statements are not consolidated with Parent’s financial statements.

     5.5 Inspection. Permit Agent, Regiment and each of their duly authorized representatives
or agents to visit any of its properties and inspect any of its assets or books and records, to
examine and make copies of its books and records, and to discuss its affairs, finances, and
accounts with, and to be advised as to the same by, its officers and employees at such reasonable
times and intervals as Agent or any such Lender may designate and, so long as no Default or Event
of Default then exists, (i) up to two such visits per calendar year shall be at the sole cost of
Borrowers (it being understood and agreed that except as otherwise expressly provided in this
Section with respect to visits, nothing in this Section 5.5 shall limit in any respect the
obligation of Parent and its Subsidiaries to pay other Obligations and Lender Group Expenses,
including, without limitation, all out-of-pocket fees, costs and expenses in connection with the
preparation and delivery of Reserve Reports and all fees and charges set forth in the Fee Letter),
and (ii) such visits shall be with reasonable prior notice to Administrative Borrower.

     5.6 Maintenance of Properties. Parent and its Subsidiaries will:

          (a) prudently operate their Oil and Gas Properties for the production of Hydrocarbons, operate
their other Properties and, to the extent Parent or one of its Subsidiaries is not the operator of
a Property in which it has an interest, Borrowers shall use reasonable efforts to cause the
operator to operate such Property, in each case in a careful and efficient manner in accordance
with the usual and customary practices of the industry, in substantial compliance with all
applicable contracts and agreements, in the case of Oil and Gas Properties in accordance with good
engineering practices and in all cases in compliance in all respects with all laws, including,
without limitation, applicable proration requirements and Environmental Laws, and all applicable
laws, rules and regulations of every other Governmental Authority from time to time constituted to
regulate the development and operation of their

- 38 -

 

Oil and Gas Properties and the production and sale of Hydrocarbons and other minerals
therefrom, except, in each case, where the failure to comply could not (either individually or in
the aggregate) reasonably be expected to result in a Material Adverse Change;

          (b) keep and maintain all Property material to the conduct of their business in good working
order and condition, ordinary wear and tear excepted, preserve, maintain and keep in good repair,
working order and efficiency (ordinary wear and tear excepted) all of their material Oil and Gas
Properties and other material Properties, including, without limitation, all equipment, machinery,
facilities, and marketing, gathering, transportation and processing assets and, from time to time,
will make all the reasonably necessary repairs, renewals and replacements so that at all times the
state and conditions of such Oil and Gas Properties and other material Properties will be fully
preserved and maintained, except to the extent a portion of such assets is no longer capable of
producing Hydrocarbons in economically reasonable amounts;

          (c) promptly pay and discharge, or make reasonable and customary efforts to cause to be paid
and discharged, all delay rentals, royalties, expenses and indebtedness accruing under the leases
or other agreements affecting or pertaining to their Oil and Gas Properties and will do all other
things necessary to keep unimpaired their rights with respect thereto and prevent any forfeiture
thereof or default thereunder; and

          (d) promptly perform or make reasonable and customary efforts to cause to be performed, in
accordance with industry standards, the obligations required by each and all of the assignments,
deeds, leases, sub-leases, contracts and agreements affecting their interests in their Oil and Gas
Properties and other material Properties and all the accompanying elements in quantities and at
prices providing for continued efficient and profitable operations of business and do all other
things necessary to keep unimpaired, except for Permitted Liens, their rights with respect thereto
and prevent any forfeiture thereof or a default thereunder, except to the extent a portion of such
properties is no longer capable of producing Hydrocarbons in economically reasonable amounts.

     5.7 Taxes. Cause all assessments and taxes, whether real, personal, or otherwise, due or
payable by, or imposed, levied, or assessed against Parent and its Subsidiaries or any of their
respective assets to be paid in full, before delinquency or before the expiration of any extension
period, except to the extent that the validity of such assessment or tax shall be the subject of a
Permitted Protest. Parent and its Subsidiaries will make timely payment or deposit of all tax
payments and withholding taxes required of them by applicable laws, including those laws concerning
F.I.C.A., F.U.T.A., state disability, and local, state, and federal income taxes, and will, upon
request, furnish Agent with proof satisfactory to Agent indicating that the applicable Borrower
have made such payments or deposits.

     5.8 Insurance.

          (a) At Borrowers’ expense, maintain insurance respecting their and their Subsidiaries assets
wherever located, covering loss or damage by fire, theft, explosion, and all other hazards and
risks as ordinarily are insured against by other Persons engaged in the same or similar
businesses. All such policies of insurance shall be in such amounts and with such insurance
companies as are reasonably satisfactory to Agent. Borrowers shall deliver copies of all such
policies to Agent with an endorsement naming Agent (on behalf of the Lenders) as the sole loss
payee (under a satisfactory lender’s loss payable endorsement) or additional insured, as
appropriate. Each policy of insurance or endorsement shall contain a clause requiring the
insurer to give not less than 30 days prior written notice to Agent in the event of cancellation
of the policy for any reason whatsoever. During the period of the drilling of wells and the
construction of any other improvements comprising a part of the Oil and Gas Properties of
Borrowers, Borrowers shall, and shall cause its contractors or

- 39 -

 

subcontractors to, obtain and maintain well control insurance (including coverage for costs
and redrilling), in such form and amounts as is customary in the industry, and worker’s
compensation insurance covering all Persons employed by Borrowers or such contractors or
subcontractors, as applicable, or their agents or further subcontractors of any tier in
connection with any construction affecting such Oil and Gas Properties, including, without
limitation, all agents and employees of Borrowers and their subcontractors with respect to whom
death or bodily injury claims could be asserted against Borrowers. If Borrowers at any time or
times hereafter shall fail to obtain or maintain any of the policies of insurance required above
or to pay all premiums relating thereto, Agent may at any time or times thereafter obtain and
maintain such policies of insurance and pay such premiums and take any other action with respect
thereto which Agent deems advisable. Agent shall have no obligation to obtain insurance for
Borrowers or pay any premiums therefor. By doing so, Agent shall not be deemed to have waived
any Default or Event of Default arising from Borrowers’ failure to maintain such insurance or pay
any premiums therefor. All sums so disbursed, including reasonable attorneys’ fees, court costs
and other charges related thereto, shall be payable on demand by Borrowers to Agent and shall be
additional Obligations hereunder secured by the Collateral.

          (b) Administrative Borrower shall give Agent prompt notice of any loss exceeding $100,000
covered by such insurance. So long as no Event of Default has occurred and is continuing,
Borrowers shall have the exclusive right to adjust any losses payable under any such insurance
policies which are less than $100,000. Following the occurrence and during the continuation of
an Event of Default, or in the case of any losses payable under such insurance exceeding
$100,000, Agent shall have the exclusive right to adjust any losses payable under any such
insurance policies, without any liability to Borrowers whatsoever in respect of such adjustments.

          (c) Borrowers will not take out separate insurance concurrent in form or contributing in the
event of loss with that required to be maintained under this Section 5.8, unless Agent is
included thereon as an additional insured or loss payee under a lender’s loss payable
endorsement. Administrative Borrower shall notify Agent promptly whenever such separate
insurance is taken out, specifying the insurer and the type and amount of insurance provided
thereunder as to the policies evidencing the same, and copies of such policies shall be provided
to Agent promptly after receipt by Loan Parties thereof.

     5.9 Compliance with Laws. Comply with the requirements of all applicable laws, rules,
regulations, and orders of any Governmental Authority, other than Environmental Laws (which are
addressed in Section 5.12 below) and laws (other than Environmental Laws), rules,
regulations, and orders the non-compliance with which, individually or in the aggregate, could not
reasonably be expected to result in a Material Adverse Change. Each Borrower and each of its
Subsidiaries shall obtain and maintain all material licenses, permits, franchises, and governmental
authorizations necessary to own their property and to conduct their business as conducted on the
Closing Date.

     5.10 Leases. Pay when due all rents and other amounts payable under all leases covering
any Proved Oil and Gas Property with a Total Reserve Value in excess of $100,000 and any other Real
Property material to their business or by which Borrowers’ material properties and assets are
bound, unless such payments are the subject of a Permitted Protest.

     5.11 Existence. At all times preserve and keep in full force and effect each Borrower’s
and each of its Subsidiaries’, valid existence and good standing and, except as could not
reasonably be expected to result in a Material Adverse Change to Parent and its Subsidiaries, taken
as a whole, any rights, franchises, permits, licenses, accreditations, authorizations, or other
approvals material to their businesses.

     5.12 Environmental.

          (a) Keep any Real Property free of any Environmental Liens or post bonds or other financial
assurances sufficient to satisfy the obligations or liability evidenced by such Environmental
Liens,

          (b) Comply, in all material respects, with all Environmental Laws and Environmental Permits;
obtain and maintain in full force and effect all material Environmental Permits; and conduct all
actions, including Response Actions, required under any Environmental Actions or applicable
Environmental Laws, and in material compliance with, the requirements of any Governmental Authority
and applicable Environmental Laws;

          (c) Do or cause to be done all things necessary to prevent any Release in, on, under, to or
from any Real Property except in full compliance with applicable Environmental Laws or an
Environmental Permit, and ensure that there shall be no Hazardous Materials in, on, under or from
any Real Property except those that are used, stored, handled and managed in material compliance
with applicable Environmental Laws;

          (d) Undertake all actions, including Response Actions, necessary, at the sole cost and expense
of Borrowers, to address (i) any Environmental Action and any obligations thereunder; (ii) any
Release at, from or onto any Real Property as required pursuant to Environmental Law or the
requirements of any Governmental Authority; and (iii) Environmental Liability;

          (e) Diligently pursue and use commercially reasonable efforts to cause any Person with an
indemnity, contribution or other obligation to any of the Loan Parties or their Subsidiaries
relating to any Environmental Action or compliance with or liability under Environmental Law to
satisfy such obligations in full and in a timely manner; and shall not amend in any way or waive
any or all rights to such obligations without the prior written consent of Agent;

          (f) Upon Agent’s reasonable request, promptly provide to Agent documentation reasonably
acceptable to Agent of compliance with items (a) through (e), including, without limitation, within
45 days following a written request of Agent, but no more frequently than once each year unless an
Event of Default exists, pursuant to Section 5.12(g) below, or a Default caused by reason
of a breach of Sections 4.11 or 5.12 herein, provide Agent with an environmental
assessment, including where appropriate any soil and/or groundwater sampling, prepared by an
environmental consulting firm reasonably acceptable to Agent, and in form and substance reasonably
acceptable to Agent; and

          (g) Promptly, but in any event within 10 days of its obtaining knowledge or receipt of notice
thereof, provide Agent with written notice of, and all data, information and reports generated or
prepared in connection with, any of the following: (i) an Environmental Lien has been filed or is
threatened against the Real Property or any personal property of Parent or any of its Subsidiaries,
(ii) commencement of any material Environmental Action or notice that a material Environmental
Action will be filed against Parent or any of its Subsidiaries, and (iii) any Release or threatened
Release of a reportable quantity, and that could reasonably be expected to result in a material
Environmental Liability, in, on, under, at, from or migrating to any Real Property owned, leased or
operated by Parent or any of its Subsidiaries, except as otherwise pursuant to and in compliance
with the terms and conditions of an Environmental Permit, (iv) any material non-compliance with, or
violation of, any Environmental Law applicable to Parent or any of its Subsidiaries, any of Parent
or any of its Subsidiaries’ business and any Real Property, (v) any Response Action which could
reasonably be expected to result in a material Environmental Liability, (vi) any notice or other
communication received by Parent or any of its

- 41 -

 

Subsidiaries from any Person or Governmental Authority relating to any material Environmental
Liability.

     5.13 Disclosure Updates. Promptly and in no event later than 5 Business Days after
obtaining knowledge thereof, notify Agent if any written information, exhibit, or report furnished
to the Lender Group contained, at the time it was furnished, any untrue statement of a material
fact or omitted to state any material fact necessary to make the statements contained therein not
misleading in light of the circumstances in which made. The foregoing to the contrary
notwithstanding, any notification pursuant to the foregoing provision will not cure or remedy the
effect of the prior untrue statement of a material fact or omission of any material fact nor shall
any such notification have the effect of amending or modifying this Agreement or any of the
Schedules hereto.

     5.14 Control Agreements. As required herein, take all reasonable steps in order for Agent
to obtain control in accordance with Sections 8-106, 9-104, 9-105, 9-106, and 9-107 of the Code
with respect to (subject to the proviso contained in Section 6.11) all of its Securities
Accounts, Deposit Accounts, electronic chattel paper, investment property, and letter-of-credit
rights.

     5.15 Formation of Subsidiaries. To the extent expressly permitted under this Agreement, if
at the time that any Borrower or any Guarantor forms any direct or indirect Subsidiary or acquires
any direct or indirect Subsidiary after the Closing Date, prior to formation or acquisition, such
Borrower or such Guarantor shall (a) cause such new Subsidiary to provide to Agent a joinder to
this Agreement or to the Guaranty (as the Agent shall determine) and the Security Agreement,
together with such other security documents (including Mortgages with respect to any Real Property
of such new Subsidiary), as well as appropriate financing statements (and with respect to all
property subject to a Mortgage, fixture filings), all in form and substance satisfactory to Agent
(including being sufficient to grant Agent a first priority Lien (subject to Permitted Liens and
in the case of the Oil and Gas Properties subject to the Limited Priority Exception for 20% of TRV)
in and to the assets of such newly formed or acquired Subsidiary), (b) provide to Agent a pledge
agreement and appropriate certificates and powers or financing statements, hypothecating all of the
direct or beneficial ownership interest in such new Subsidiary, in form and substance satisfactory
to Agent, and (c) provide to Agent all other documentation, including one or more opinions of
counsel satisfactory to Agent, which in its opinion is appropriate with respect to the execution
and delivery of the applicable documentation referred to above (including policies of title
insurance or other documentation with respect to all property subject to a Mortgage, subject to any
limitation expressly set forth in Section 5.21). Any document, agreement, or instrument
executed or issued pursuant to this Section 5.15 shall be a Loan Document.

     5.16 Further Assurances. At any time upon the request of Agent, Borrowers shall execute or
deliver to Agent, and shall cause their Subsidiaries to execute or deliver to Agent, any and all
financing statements, fixture filings, security agreements, pledges, assignments, endorsements of
certificates of title, mortgages, deeds of trust, opinions of counsel, and all other documents
(collectively, the “Additional Documents”) that Agent may request in form and substance reasonably
satisfactory to Agent, to create, perfect, and continue perfected or to better perfect Agent’s
Liens with respect to Oil and Gas Properties and all of the other properties and assets of Parent
and its Subsidiaries (whether now owned or hereafter arising or acquired, tangible or intangible,
real or personal), to create and perfect Liens in favor of Agent in any Real Property acquired by
Parent or any of its Subsidiaries after the Closing Date, and in order to fully consummate all of
the transactions contemplated hereby and under the other Loan Documents, provided that Section
5.21 shall govern the obligation of Borrowers to deliver title information with respect to Oil
and Gas Properties. To the maximum extent permitted by applicable law, Parent and its Subsidiaries
authorize Agent to execute any such Additional Documents in their or their Subsidiaries’ names, as
applicable and to file such executed Additional Documents in any appropriate filing office. With
respect to any Oil and Gas Property that Parent or any of its Subsidiaries acquires after the
Closing

- 42 -

 

Date or any post Closing Date discovery and/or confirmation of the existence of Hydrocarbons in any
property owned or leased by Parent or of its Subsidiaries that is not subject to an existing
Mortgage, Parent and its Subsidiaries shall promptly: (a) notify Agent of such acquisition (not
more than 5 Business Days after such acquisition), (b) execute and deliver to Agent such additional
Mortgages or amendments to the Mortgages or such other documents as Agent shall deem necessary or
advisable to grant to Agent, for the benefit of the Lenders, a perfected first priority Lien on
such Oil and Gas Property (subject to Permitted Liens and in the case of the Oil and Gas Properties
subject to the Limited Priority Exception for 20% of TRV); and (b) take all actions necessary or
advisable to cause such Lien to be duly perfected in accordance with all applicable law, including,
without limitation, the filing of Mortgages (within 20 days after Agent’s request therefor), or UCC
financing statements in such jurisdictions as may be requested by Agent.

     5.17 Material Contracts. Contemporaneously with the delivery of each Compliance
Certificate pursuant hereto, provide Agent with copies of (a) each Material Contract entered into
since the delivery of the previous Compliance Certificate, and (b) each amendment or modification
of any Material Contract entered into since the delivery of the previous Compliance Certificate.

     5.18 Intellectual Property. Parent and each Subsidiary will conduct its business and
affairs without material infringement of or material interference with any intellectual property of
any other Person.

     5.19 Exercise of Rights. Borrowers shall enforce all of its material rights, including,
without limitation, all material indemnification rights, and pursue all material remedies available
to Borrowers with diligence and in good faith in connection with the enforcement of any such
rights.

     5.20 Reserve Reports.

          (a) On or before April 3rd and October 3rd of each year, commencing April 3, 2008, Parent and
its Subsidiaries shall furnish to Agent and the Lenders a Reserve Report as of the immediately
preceding January 1 or July 1, as applicable. The Reserve Report as of January 1 of each year
shall be prepared by one or more independent third party Petroleum Engineers reasonably acceptable
to Agent and the Reserve Report as of July 1 of each year shall be prepared by or under the
supervision of the chief engineer of Borrowers who shall certify such Reserve Report to be true and
accurate in all material respects and to have been prepared in accordance with the procedures used
in the immediately preceding January 1 Reserve Report.

          (b) In the event of an Interim Redetermination, Parent and its Subsidiaries shall furnish to
Agent and the Lenders a Reserve Report prepared by or under the supervision of the chief engineer
of Borrowers who shall certify such Reserve Report to be true and accurate in all material respects
and to have been prepared in accordance with the procedures used in the immediately preceding
January 1 Reserve Report. For any Interim Redetermination requested by Agent or Borrowers pursuant
to Section 2.1, Borrowers shall provide such Reserve Report with an “as of” date as
required by Agent as soon as possible, but in any event no later than thirty (30) days following
the receipt of such request.

          (c) With the delivery of each Reserve Report, Parent and its Subsidiaries shall provide to
Agent and the Lenders a certificate from a Responsible Officer certifying that in all material
respects: (i) the information contained in the Reserve Report and any other information delivered
in connection therewith is true and correct, (ii) Parent and its Subsidiaries owns good and
defensible title to the Proved Oil and Gas Properties evaluated in such Reserve Report and such
Properties are free of all Liens except for Liens permitted under clauses (a), (b), (e), (k) and
(m) of the definition of “Permitted Liens,” (iii) except as set forth on an exhibit to the
certificate, on a net basis there are no gas imbalances,

- 43 -

 

take or pay or other prepayments in excess of the volume specified in Section 4.25
with respect to their Oil and Gas Properties evaluated in such Reserve Report that would require
Parent or any of its Subsidiaries to deliver Hydrocarbons either generally or produced from such
Oil and Gas Properties at some future time without then or thereafter receiving full payment
therefor, (iv) none of their Proved Oil and Gas Properties have been sold since the date of the
last Borrowing Base determination except as set forth on an exhibit to the certificate, which
certificate shall list all of their Proved Oil and Gas Properties sold and in such detail as
reasonably required by Agent, (v) attached to the certificate is a list of all marketing agreements
entered into subsequent to the later of the date hereof or the most recently delivered Reserve
Report that Borrowers could reasonably be expected to have been obligated to list on Schedule
4.28 had such agreement been in effect on the date hereof, (vi) attached thereto is a schedule
of the Oil and Gas Properties evaluated by such Reserve Report that are Mortgaged Properties and
demonstrating the percentage of the Total Reserve Value that such Mortgaged Properties represent,
including a listing of the Mortgaged Properties at such time that are equal to at least 80% of the
Total Reserve Value of the Proved Oil and Gas Properties evaluated by such Reserve Report and for
which satisfactory title information has been received by Agent pursuant to Section 5.21, and (vii)
all Oil and Gas Properties are subject to the Security Documents securing the Obligations, and such
Security Documents constitute legal, valid and duly perfected, first priority security interests
and Liens in favor of Agent in such properties and in the oil and gas attributable to such
properties and proceeds thereof; subject only to Permitted Liens and the Limited Priority Exception
for 20% of TRV set forth in Section 4.6(e).

     5.21 Title Information.

          (a) On or prior to the Closing Date, unless otherwise agreed to by Agent, Parent and its
Subsidiaries will deliver title information in form and substance acceptable to Agent covering
enough of the Oil and Gas Properties evaluated by the Initial Reserve Report, so that Agent shall
have received, together with title information previously delivered to Agent, satisfactory title
information on at least 80% of the Total Reserve Value of the Proved Oil and Gas Properties
evaluated by the Initial Reserve Report.

          (b) On or before the delivery to Agent and the Lenders of each Reserve Report required by
Section 5.20(a), Parent and its Subsidiaries will deliver title information in form and
substance acceptable to Agent covering enough of the Oil and Gas Properties evaluated by such
Reserve Report that were not included in the immediately preceding Reserve Report, so that Agent
shall have received together with title information previously delivered to Agent, satisfactory
title information on at least 80% of the Total Reserve Value of the Proved Oil and Gas Properties
evaluated by such Reserve Report.

          (c) If Parent or its Subsidiaries have provided title information for additional Properties
under Section 5.21(b), Parent and its Subsidiaries shall, within 60 days of notice from
Agent that title defects or exceptions exist with respect to such additional Properties, either (i)
cure any such title defects or exceptions (including defects or exceptions as to priority) which
are not permitted by Section 6.2 raised by such information, (ii) substitute acceptable
Mortgaged Properties with no title defects or exceptions except for Permitted Liens (other than
Permitted Liens described in clause (g) of such definition) having an equivalent value or (iii)
deliver title information in form and substance reasonably acceptable to Agent so that Agent shall
have received, together with title information previously delivered to Agent, satisfactory title
information on at least 80% of the Total Reserve Value of the Oil and Gas Properties evaluated by
such Reserve Report. For purposes of clarity, delivery of such title information in respect of 80%
of the value of such Oil and Gas Properties shall not preclude Agent from establishing reserves
against the then-existing Borrowing Base pursuant to Section 2.1(b).

- 44 -

 

          (d) If Parent and its Subsidiaries are unable to cure any title defect requested by Agent or
the Lenders to be cured within the 60-day period or Parent or any of its Subsidiaries do not comply
with the requirements to provide acceptable title information covering 80% of the Total Reserve
Value of the Oil and Gas Properties evaluated in the most recent Reserve Report, such default shall
not be a Default, but instead Agent and/or the Required Lenders shall have the right to exercise
the following remedy in their sole discretion from time to time, and any failure to so exercise
this remedy at any time shall not be a waiver as to future exercise of the remedy by Agent or the
Lenders. To the extent that Agent or the Required Lenders are not reasonably satisfied with title
to any Mortgaged Property after the 60-day period has elapsed, such unacceptable Mortgaged Property

Pension Liability among all Pension Plans at any time exceeds $250,000; or (iii) Parent or any of
its Subsidiaries or any ERISA Affiliate shall fail to pay when due, after the expiration of any
applicable grace period, any installment payment with respect to its withdrawal liability under
Section 4201 of ERISA under a Multiemployer Plan in an aggregate amount in excess of $250,000; or

     7.16 Any Material Adverse Change shall have occurred.

8. THE LENDER GROUP’S RIGHTS AND REMEDIES.

     8.1 Rights and Remedies. Upon the occurrence, and during the continuation, of an Event of
Default, Agent at the request of the Required Lenders for the benefit of the Lender Group shall
without notice or demand, all of which are authorized by Borrowers:

          (a) Declare all or any portion of the Obligations, whether evidenced by this Agreement, by
any of the other Loan Documents, or otherwise, immediately due and payable;

          (b) Cease advancing money or extending credit to or for the benefit of Borrowers under this
Agreement, under any of the Loan Documents, or under any other agreement between Borrowers and
the Lender Group;

          (c) Agent, on behalf of the Lender Group, may foreclose any or all of the Mortgages and sell
the Real Property Collateral or Oil and Gas Properties or cause the Real Property Collateral or
Oil and Gas Properties to be sold in accordance with the provisions of the Mortgages and
applicable law, and exercise any and all other rights or remedies available to Agent, on behalf
of the Lender Group, under the Mortgages, any of the other Loan Documents, at law or in equity
with respect to the Collateral encumbered by the Mortgages;

          (d) Terminate this Agreement and any of the other Loan Documents as to any future liability
or obligation of the Lender Group, but without affecting any of Agent’s Liens in the Collateral
and without affecting the Obligations; and

          (e) The Lender Group shall have all other rights and remedies available at law or in equity
or pursuant to any other Loan Document.

- 54 -

 

The foregoing to the contrary notwithstanding, upon the occurrence of any Event of Default
described in Section 7.4 or Section 7.5, in addition to the remedies set forth
above, without any notice to Borrowers or any other Person or any act by the Lender Group, the
Commitments shall automatically terminate and the Obligations then outstanding, together with all
accrued and unpaid interest thereon and all fees and all other amounts due under this Agreement and
the other Loan Documents, shall automatically and immediately become due and payable, without
presentment, demand, protest, or notice of any kind, all of which are expressly waived by
Borrowers.

     8.2 Remedies Cumulative . The rights and remedies of the Lender Group under this
Agreement, the other Loan Documents, and all other agreements shall be cumulative. The Lender
Group shall have all other rights and remedies not inconsistent herewith as provided under the
Code, by law, or in equity. No exercise by the Lender Group of one right or remedy shall be deemed
an election, and no waiver by the Lender Group of any Event of Default shall be deemed a continuing
waiver. No delay by the Lender Group shall constitute a waiver, election, or acquiescence by it.

9. TAXES AND EXPENSES.

     If Parent or any of its Subsidiaries fail to pay any monies (whether taxes, assessments,
insurance premiums, or, in the case of leased properties or assets, rents or other amounts payable
under such leases) due to third Persons, or fail to make any deposits or furnish any required proof
of payment or deposit, all as required under the terms of this Agreement, then, Agent, in its sole
discretion and without prior notice to any Borrower, may do any or all of the following: (a) make
payment of the same or any part thereof, (b) set up such reserves against the Borrowing Base or the
Maximum Revolver Amount as Agent deems necessary to protect the Lender Group from the exposure
created by such failure, or (c) in the case of the failure to comply with Section 5.8
hereof, obtain and maintain insurance policies of the type described in Section 5.8 and
take any action with respect to such policies as Agent deems prudent. Any such amounts paid by
Agent shall constitute Lender Group Expenses and any such payments shall not constitute an
agreement by the Lender Group to make similar payments in the future or a waiver by the Lender
Group of any Event of Default under this Agreement. Agent need not inquire as to, or contest the
validity of, any such expense, tax, or Lien and the receipt of the usual official notice for the
payment thereof shall be conclusive evidence that the same was validly due and owing.

10. WAIVERS; INDEMNIFICATION.

     10.1 Demand; Protest; etc. Each Borrower waives demand, protest, notice of protest, notice
of default or dishonor, notice of payment and nonpayment, nonpayment at maturity, release,
compromise, settlement, extension, or renewal of documents, instruments, chattel paper, and
guarantees at any time held by the Lender Group on which any such Borrower may in any way be
liable.

     10.2 The Lender Group’s Liability for Collateral. Each Borrower hereby agrees that:
(a) so long as Agent complies with its obligations, if any, under the Code, the Lender Group shall
not in any way or manner be liable or responsible for: (i) the safekeeping of the Collateral, (ii)
any loss or damage thereto occurring or arising in any manner or fashion from any cause, (iii) any
diminution in the value thereof, or (iv) any act or default of any carrier, warehouseman, bailee,
forwarding agency, or other Person, and (b) all risk of loss, damage, or destruction of the
Collateral shall be borne by Borrowers.

     10.3 Indemnification. Each Borrower shall pay, indemnify, defend, and hold Agent-Related
Persons, the Lender-Related Persons, and each Participant (each, an “Indemnified Person”) harmless
(to the fullest extent permitted by law) from and against any and all claims, demands, suits,
actions, investigations, proceedings, liabilities, fines, costs, penalties, and damages, and all
reasonable fees and disbursements of attorneys, experts, or consultants and all other costs and
expenses actually incurred in

- 55 -

 

connection therewith or in connection with the enforcement of this
indemnification (as and when they are incurred and irrespective of whether suit is brought), at any
time asserted against, imposed upon, or incurred by any of them (a) in connection with or as a
result of or related to the execution, delivery, enforcement, performance, or administration
(including any restructuring or workout with respect hereto) of this Agreement, any of the other
Loan Documents, or the transactions contemplated hereby or thereby or the monitoring of Parent and
its Subsidiaries’ compliance with the terms of the Loan Documents, (b) with respect to any
investigation, litigation, or proceeding related to this Agreement, any other Loan Document, or the
use of the proceeds of the credit provided hereunder (irrespective of whether any Indemnified
Person is a party thereto), or any act, omission, event, or circumstance in any manner related
thereto, and (c) in connection with or arising out of any presence or Release of Hazardous
Materials, any Environmental Actions, any Environmental Liabilities or any Response Actions related
in any way to any assets or properties of Parent or any of its Subsidiaries (each and all of the
foregoing, the “Indemnified Liabilities”). The foregoing to the contrary notwithstanding,
Borrowers shall have no obligation to any Indemnified Person under this Section 10.3 with
respect to any Indemnified Liability that a court of competent jurisdiction finally determines to
have resulted from the gross negligence or willful misconduct of such Indemnified Person. This
provision shall survive the termination of this Agreement and the repayment of the Obligations. If
any Indemnified Person makes any payment to any other Indemnified Person with respect to an
Indemnified Liability as to which Borrowers were required to indemnify the Indemnified Person
receiving such payment, the Indemnified Person making such payment is entitled to be indemnified
and reimbursed by Borrowers with respect thereto. WITHOUT LIMITATION, THE FOREGOING INDEMNITY
SHALL APPLY TO EACH INDEMNIFIED PERSON WITH RESPECT TO INDEMNIFIED LIABILITIES WHICH IN WHOLE OR IN
PART ARE CAUSED BY OR ARISE OUT OF ANY NEGLIGENT ACT OR OMISSION OF SUCH INDEMNIFIED PERSON OR OF
ANY OTHER PERSON.

11. NOTICES.

          Unless otherwise provided in this Agreement, all notices or demands by Borrowers or Agent to
the other relating to this Agreement or any other Loan Document shall be in writing and (except for
financial statements and other informational documents which may be sent by first-class mail,

prepaid, return receipt requested), overnight courier, electronic mail (at such email addresses as

12. CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER.

          (a) THE VALIDITY OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (UNLESS EXPRESSLY PROVIDED
TO THE CONTRARY IN ANOTHER LOAN DOCUMENT IN RESPECT OF SUCH OTHER LOAN DOCUMENT), THE
CONSTRUCTION, INTERPRETATION, AND ENFORCEMENT HEREOF AND THEREOF,
AND THE RIGHTS OF THE PARTIES HERETO AND THERETO WITH RESPECT TO ALL MATTERS ARISING
HEREUNDER OR THEREUNDER OR RELATED HERETO OR THERETO SHALL BE DETERMINED UNDER, GOVERNED BY, AND

          (b) THE PARTIES AGREE THAT ALL ACTIONS OR PROCEEDINGS ARISING IN CONNECTION WITH THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS SHALL BE TRIED AND LITIGATED ONLY IN THE STATE AND, TO THE
EXTENT PERMITTED BY APPLICABLE LAW, FEDERAL COURTS LOCATED IN THE COUNTY OF NEW YORK, STATE OF
NEW YORK; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT AGAINST ANY
COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT AGENT’S OPTION, IN THE COURTS OF ANY JURISDICTION
WHERE AGENT ELECTS TO BRING SUCH ACTION OR WHERE SUCH COLLATERAL OR OTHER PROPERTY MAY BE FOUND.
BORROWERS AND EACH MEMBER OF THE LENDER GROUP WAIVE, TO THE EXTENT PERMITTED UNDER APPLICABLE

          (c) BORROWERS AND EACH MEMBER OF THE LENDER GROUP HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A

CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS
OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH
OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS. BORROWERS AND EACH MEMBER OF THE
LENDER GROUP REPRESENT THAT EACH HAS REVIEWED THIS WAIVER AND EACH KNOWINGLY AND VOLUNTARILY
WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. IN THE EVENT OF
LITIGATION, A COPY OF THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

13. ASSIGNMENTS AND PARTICIPATIONS; SUCCESSORS.

     13.1 Assignments and Participations.

          (a) Any Lender may at any time assign and delegate to one or more assignees (each an
“Assignee”) all or any portion of the Obligations, the Commitments and the other rights and
obligations of such Lender hereunder and under the other Loan Documents, in a minimum amount
(unless waived by Agent) of $1,000,000 (except such minimum amount shall not apply to (x) an
assignment or delegation by any Lender to any other Lender or an Affiliate of any Lender or an
Approved Fund or (y) a group of new Lenders, each of whom is an Affiliate of each other or a fund
or account managed by any such new Lender or an Affiliate of such new Lender to the extent that the
aggregate amount to be assigned to all such new Lenders is at least $3,000,000); provided,
however, that Borrowers and Agent may continue to deal solely and directly with such Lender
in connection with the interest so assigned to an Assignee until (i) written notice of such
assignment, together with payment instructions, addresses, and related information with respect to
the Assignee, have been given to Administrative Borrower and Agent by such Lender and the Assignee,
(ii) such Lender and its Assignee have delivered to Administrative Borrower and Agent an Assignment
and Acceptance and Agent has notified the assigning Lender of its receipt thereof in accordance
with Section 13.1(b), and (iii) unless waived by Agent, the assigning Lender or Assignee
has paid to Agent for Agent’s separate account a processing fee in the amount of $3,500.
Anything contained herein to the contrary notwithstanding, the payment of any fees shall not
be required if such assignment is in connection with any merger, consolidation, sale, transfer, or
other disposition of all or any substantial portion of the business or loan portfolio of the
assigning Lender.

          (b) From and after the date that Agent notifies the assigning Lender (with a copy to
Administrative Borrower) that it has received an executed Assignment and Acceptance and, if
applicable, payment of the required processing fee, (i) the Assignee thereunder shall be a party
hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment and Acceptance, shall have the rights and obligations of a Lender under the Loan
Documents, and (ii) the assigning Lender shall, to the extent that rights and obligations hereunder
and under the other Loan Documents have been assigned by it pursuant to such Assignment and
Acceptance, relinquish its rights (except with respect to Section 10.3 hereof) and be
released from any future obligations under this Agreement (and in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations
under this Agreement and the other Loan Documents, such Lender shall cease to be a party hereto and
thereto), and such assignment shall effect a novation among Borrowers, the assigning Lender, and
the Assignee; provided, however, that nothing contained herein shall release any
assigning Lender from obligations that survive the termination of this Agreement, including such
assigning Lender’s obligations under Section 15 and Section 17.9(a) of this
Agreement.

          (c) By executing and delivering an Assignment and Acceptance, the assigning Lender thereunder
and the Assignee thereunder confirm to and agree with each other and the other parties hereto as
follows: (i) other than as provided in such Assignment and Acceptance, such assigning Lender makes
no representation or warranty and assumes no responsibility with respect to any statements,

 - 58 - 

 

warranties or representations made in or in connection with this Agreement or the execution,
legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any
other Loan Document furnished pursuant hereto, (ii) such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to the financial condition of Borrowers or
the performance or observance by Borrowers of any of their obligations under this Agreement or any
other Loan Document furnished pursuant hereto, (iii) such Assignee confirms that it has received a
copy of this Agreement, together with such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such Assignment and
Acceptance, (iv) such Assignee will, independently and without reliance upon Agent, such assigning
Lender or any other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or not taking action
under this Agreement, (v) such Assignee appoints and authorizes Agent to take such actions and to
exercise such powers under this Agreement as are delegated to Agent, by the terms hereof, together
with such powers as are reasonably incidental thereto, and (vi) such Assignee agrees that it will
perform all of the obligations which by the terms of this Agreement are required to be performed by
it as a Lender.

          (d) Immediately upon Agent’s receipt of the required processing fee, if applicable, and
delivery of notice to the assigning Lender pursuant to Section 13.1(b), this Agreement
shall be deemed to be amended to the extent, but only to the extent, necessary to reflect the
addition of the Assignee and the resulting adjustment of the Commitments arising therefrom. The
Commitment allocated to each Assignee shall reduce such Commitments of the assigning Lender pro
tanto.

          (e) Any Lender may at any time sell to one or more commercial banks, financial institutions,
or other Persons (a “Participant”) participating interests in all or any portion of its
Obligations, its Commitment, and the other rights and interests of that Lender (the
“Originating Lender”) hereunder and under the other Loan Documents; provided,
however, that (i) the Originating Lender shall remain a “Lender” for all purposes of this
Agreement and the other Loan Documents and the Participant receiving the participating interest in
the Obligations, the Commitments, and the other rights and interests
of the Originating Lender hereunder shall not constitute a “Lender” hereunder or under the
other Loan Documents and the Originating Lender’s obligations under this Agreement shall remain
unchanged, (ii) the Originating Lender shall remain solely responsible for the performance of such
obligations, (iii) Borrowers, Agent, and the Lenders shall continue to deal solely and directly
with the Originating Lender in connection with the Originating Lender’s rights and obligations
under this Agreement and the other Loan Documents, (iv) no Lender shall transfer or grant any
participating interest under which the Participant has the right to approve any amendment to, or
any consent or waiver with respect to, this Agreement or any other Loan Document, except to the
extent such amendment to, or consent or waiver with respect to this Agreement or of any other Loan
Document would (A) extend the final maturity date of the Obligations hereunder in which such
Participant is participating, (B) reduce the interest rate applicable to the Obligations hereunder
in which such Participant is participating, (C) release all or substantially all of the Collateral
or guaranties (except to the extent expressly provided herein or in any of the Loan Documents)
supporting the Obligations hereunder in which such Participant is participating, (D) postpone the
payment of, or reduce the amount of, the interest or fees payable to such Participant through such
Lender, or (E) change the amount or due dates of scheduled principal repayments or prepayments or
premiums, and (v) all amounts payable by Borrowers hereunder shall be determined as if such Lender
had not sold such participation, except that, if amounts outstanding under this Agreement are due
and unpaid, or shall have been declared or shall have become due and payable upon the occurrence of
an Event of Default, each Participant shall be deemed to have the right of set off in respect of
its participating interest in amounts owing under this Agreement to the same extent as if the
amount of its participating interest were owing directly to it as a Lender under this Agreement.
The rights of any Participant only shall be derivative through the Originating Lender with whom
such Participant participates and no Participant shall have any rights under this Agreement or the
other Loan Documents or any direct rights as to the

 - 59 - 

 

other Lenders, Agent, Borrowers, the
Collections of Parent or its Subsidiaries, the Collateral, or otherwise in respect of the
Obligations. No Participant shall have the right to participate directly in the making of
decisions by the Lenders among themselves. The provisions of this Section 13.1(e) are
solely for the benefit of the Lender Group and Borrowers shall not have any rights as third party
beneficiaries of any such provisions.

          (f) In connection with any such assignment or participation or proposed assignment or
participation, a Lender may, subject to the provisions of Section 17.9, disclose all
documents and information which it now or hereafter may have relating to Parent and its
Subsidiaries and their respective businesses.

          (g) Any other provision in this Agreement notwithstanding, any Lender may at any time create a
security interest in, or pledge, all or any portion of its rights under and interest in this
Agreement in favor of any Federal Reserve Bank in accordance with Regulation A of the Federal
Reserve Bank or U.S. Treasury Regulation 31 CFR §203.24, and such Federal Reserve Bank may enforce
such pledge or security interest in any manner permitted under applicable law.

     13.2 Successors. This Agreement shall bind and inure to the benefit of the respective
successors and assigns of each of the parties; provided, however, that Borrower may
not assign this Agreement or any rights or duties hereunder without the Lenders’ prior written
consent and any prohibited assignment shall be absolutely void ab initio. No consent to assignment
by the Lenders shall release Borrowers from its Obligations. A Lender may assign this Agreement
and the other Loan Documents and its rights and duties hereunder and thereunder pursuant to
Section 13.1 hereof.

14. AMENDMENTS; WAIVERS.

     14.1 Amendments and Waivers. No amendment or waiver of any provision of this Agreement or
any other Loan Document (other than Bank Product Agreements), and no consent with respect to any
departure by Borrowers therefrom, shall be effective unless the same shall be in writing and signed
by the Required Lenders (or by Agent at the written request of the Required Lenders) and
Administrative Borrower (on behalf of all Borrowers) and then any such waiver or consent shall be
effective, but only in the specific instance and for the specific purpose for which given;
provided, however, that no such waiver, amendment, or consent shall, unless in writing and signed
by all of the Lenders directly affected thereby and Administrative Borrower (on behalf of all
Borrowers), do any of the following:

          (a) increase or extend any Commitment of any Lender,

          (b) postpone or delay any date fixed by this Agreement or any other Loan Document for any
payment of principal, interest, fees, or other amounts due hereunder or under any other Loan
Document,

          (c) reduce the principal of, or the rate of interest on, any loan or other extension of credit
hereunder, or reduce any fees or other amounts payable hereunder or under any other Loan Document,

          (d) change the Pro Rata Share that is required to take any action hereunder,

          (e) amend or modify this Section or any provision of this Agreement providing for consent or
other action by all Lenders,

 - 60 - 

 

          (f) other than as permitted by Section 15.11, release Agent’s Lien in and to any of
the Collateral,

          (g) change the definition of “Required Lenders” or “Pro Rata Share”,

          (h) contractually subordinate any of Agent’s Liens,

          (i) other than in connection with a merger, liquidation, dissolution or sale of such Person
expressly permitted by the terms hereof or the other Loan Documents, release Borrowers or any
Guarantor from any obligation for the payment of money,

          (j) amend any of the provisions of Section 2.4(b)(i) or (ii),

          (k) change the definition of Borrowing Base, Maximum Revolver Amount, Term Loan Amount, or
change Section 2.1, or

          (l) amend any of the provisions of Section 15.

and, provided further, however, that no amendment, waiver or consent shall, unless
in writing and signed by Agent, Issuing Lender, or Swing Lender, as applicable, affect the rights
or duties of Agent, Issuing Lender, or Swing Lender, as applicable, under this Agreement or any
other Loan Document. The foregoing notwithstanding, any amendment, modification, waiver, consent,
termination, or release of, or with respect to, any provision of this Agreement or any other Loan
Document that relates only to the relationship of the Lender Group among themselves, and that does
not affect the rights or obligations of Borrowers, shall not require consent by or the agreement of
Borrowers.

     14.2 Replacement of Lenders.

          (a) If (i) any action to be taken by the Lender Group or Agent hereunder requires the consent,
authorization, or agreement of all Lenders, and a Lender (“Holdout Lender”) fails to give its
consent, authorization, or agreement, or (ii) any Lender (an “Increased Cost Lender”; Increased
Cost Lenders and Holdout Lenders are each referred to herein as “Replaceable Lenders”) shall give
notice to Administrative Borrower that such Lender is entitled to receive payments under
Section 2.13(d)(i) or (d)(ii) or Section 2.14, then Agent or
Administrative Borrower, upon at least 5 Business Days prior irrevocable notice to the Replaceable
Lender, may permanently replace the Replaceable Lender with one or more substitute Lenders (each, a
“Replacement Lender”; provided, that no Borrower, Guarantor or Permitted Holder or
Affiliate of a Borrower, Guarantor or Permitted Holder shall be permitted to become a Replacement
Lender), and the Replaceable Lender shall have no right to refuse to be replaced hereunder. Such
notice to replace the Replaceable Lender shall specify an effective date for such replacement,
which date shall not be later than 15 Business Days after the date such notice is given.

          (b) Prior to the effective date of such replacement, the Replaceable Lender and each
Replacement Lender shall execute and deliver an Assignment and Acceptance, subject only to the
Replaceable Lender being repaid its share of the outstanding Obligations (including an assumption
of its Pro Rata Share of the Risk Participation Liability) but without any premium or penalty of
any kind whatsoever. If the Replaceable Lender shall refuse or fail to execute and deliver any
such Assignment and Acceptance prior to the effective date of such replacement, the Replaceable
Lender shall be deemed to have executed and delivered such Assignment and Acceptance. The
replacement of any Replaceable Lender shall be made in accordance with the terms of Section 13.1.
Until such time as the Replacement Lenders shall have acquired all of the Obligations, the
Commitments, and the other rights and obligations of the Replaceable Lender hereunder and under the
other Loan Documents, the Replaceable Lender shall remain obligated to make the Replaceable
Lender’s Pro Rata Share of Advances and to purchase a

 - 61 - 

 

participation in each Letter of Credit, in an
amount equal to its Pro Rata Share of the Risk Participation Liability of such Letter of Credit.

     14.3 No Waivers; Cumulative Remedies. No failure by Agent or any Lender to exercise any
right, remedy, or option under this Agreement or any other Loan Document, or delay by Agent or any
Lender in exercising the same, will operate as a waiver thereof. No waiver by Agent or any Lender
will be effective unless it is in writing, and then only to the extent specifically stated. No
waiver by Agent or any Lender on any occasion shall affect or diminish Agent’s and each Lender’s
rights thereafter to require strict performance by Borrowers of any provision of this Agreement.
Agent’s and each Lender’s rights under this Agreement and the other Loan Documents will be
cumulative and not exclusive of any other right or remedy that Agent or any Lender may have.

15. AGENT; THE LENDER GROUP.

     15.1 Appointment and Authorization of Agent. Each Lender hereby designates and appoints
WFF as its representative under this Agreement and the other Loan Documents and each Lender hereby
irrevocably authorizes Agent to execute and deliver each of the other Loan Documents on its behalf
and to take such other action on its behalf under the provisions of this Agreement and each other
Loan Document and to exercise such powers and perform such duties as are expressly delegated to
Agent by the terms of this Agreement or any other Loan Document, together
with such powers as are reasonably incidental thereto. Agent agrees to act as such on the express
conditions contained in this Section 15. The provisions of this Section 15 are
solely for the benefit of Agent and the Lenders, and Borrowers shall have no rights as a third
party beneficiary of any of such provisions contained herein. Any provision to the contrary
contained elsewhere in this Agreement or in any other Loan Document notwithstanding, Agent shall
not have any duties or responsibilities, except those expressly set forth herein, nor shall Agent
have or be deemed to have any fiduciary relationship with any Lender, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement
or any other Loan Document or otherwise exist against Agent; it being expressly understood and
agreed that the use of the word “Agent” is for convenience only, that WFF is merely the
representative of the Lenders, and only has the contractual duties set forth herein. Except as
expressly otherwise provided in this Agreement, Agent shall have and may use its sole discretion
with respect to exercising or refraining from exercising any discretionary rights or taking or
refraining from taking any actions that Agent expressly is entitled to take or assert under or
pursuant to this Agreement and the other Loan Documents. Without limiting the generality of the
foregoing, or of any other provision of the Loan Documents that provides rights or powers to Agent,
Lenders agree that Agent shall have the right to exercise the following powers as long as this
Agreement remains in effect: (a) maintain, in accordance with its customary business practices,
ledgers and records reflecting the status of the Obligations, the Collateral, the Collections of
Parent and its Subsidiaries, and related matters, (b) execute or file any and all financing or

and pay such Lender Group Expenses as Agent may deem necessary or appropriate for the performance
and fulfillment of its functions and powers pursuant to the Loan Documents.

     15.2 Delegation of Duties. Agent may execute any of its duties under this Agreement or any
other Loan Document by or through agents, employees or attorneys in fact and shall be entitled to
advice of counsel concerning all matters pertaining to such duties. Agent shall not be responsible
for the negligence or misconduct of any agent or attorney in fact that it selects as long as such
selection was made without gross negligence or willful misconduct.

     15.3 Liability of Agent. None of Agent-Related Persons shall (a) be liable for any action
taken or omitted to be taken by any of them under or in connection with this Agreement or any other
Loan Document or the transactions contemplated hereby (except for its own gross negligence or
willful misconduct), or (b) be responsible in any manner to any of the Lenders for any recital,
statement, representation or warranty made by any Borrower or any of its Subsidiaries or
Affiliates, or any officer or director thereof, contained in this Agreement or in any other Loan
Document, or in any certificate, report, statement or other document referred to or provided for
in, or received by Agent under or in connection with, this Agreement or any other Loan Document, or
the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any
other Loan Document, or for any failure of any Borrower or its Subsidiaries or any other party to
any Loan Document to perform its obligations hereunder or thereunder. No Agent-Related
Person shall be under any obligation to any Lender to ascertain or to inquire as to the observance
or performance of any of the agreements contained in, or conditions of, this Agreement or any other
Loan Document, or to inspect the books and records or properties of Parent and its Subsidiaries.

     15.4 Reliance by Agent. Agent shall be entitled to rely, and shall be fully protected in
relying, upon any writing, resolution, notice, consent, certificate, affidavit, letter, telegram,
telefacsimile or other electronic method of transmission, telex or telephone message, statement or
other document or conversation believed by it to be genuine and correct and to have been signed,
sent, or made by the proper Person or Persons, and upon advice and statements of legal counsel
(including counsel to Borrowers or counsel to any Lender), independent accountants and other
experts selected by Agent. Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless Agent shall first receive such advice
or concurrence of the Lenders as it deems appropriate and until such instructions are received,
Agent shall act, or refrain from acting, as it deems advisable. If Agent so requests, it shall
first be indemnified to its reasonable satisfaction by the Lenders against any and all liability
and expense that may be incurred by it by reason of taking or continuing to take any such action.
Agent shall in all cases be fully protected in acting, or in refraining from acting, under this
Agreement or any other Loan Document in accordance with a request or consent of the requisite
Lenders and such request and any action taken or failure to act pursuant thereto shall be binding
upon all of the Lenders.

     15.5 Notice of Default or Event of Default. Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default, except with respect to defaults in the
payment of principal, interest, fees, and expenses required to be paid to Agent for the account of
the Lenders and, except with respect to Events of Default of which Agent has actual knowledge,
unless Agent shall have received written notice from a Lender or Administrative Borrower referring
to this Agreement, describing such Default or Event of Default, and stating that such notice is a
“notice of default.” Agent promptly will notify the Lenders of its receipt of any such notice or
of any Event of Default of which Agent has actual knowledge. If any Lender obtains actual
knowledge of any Event of Default, such Lender promptly shall notify the other Lenders and Agent of
such Event of Default. Each Lender shall be solely responsible for giving any notices to its
Participants, if any. Subject to Section 15.4, Agent shall take such action with respect
to such Default or Event of Default as may be requested by the Required Lenders in accordance with
Section 8; provided, however, that unless and until Agent has received any such request,
Agent may (but shall not be obligated to) take such action, or refrain from taking such action,
with respect to such Default or Event of Default as it shall deem advisable.

 - 63 - 

 

     15.6 Credit Decision. Each Lender acknowledges that none of Agent-Related Persons has made
any representation or warranty to it, and that no act by Agent hereinafter taken, including any
review of the affairs of Parent and its Subsidiaries or Affiliates, shall be deemed to constitute
any representation or warranty by any Agent-Related Person to any Lender. Each Lender represents
to Agent that it has, independently and without reliance upon any Agent-Related Person and based on
such documents and information as it has deemed appropriate, made its own appraisal of and
investigation into the business, prospects, operations, property, financial and other condition and
creditworthiness of Borrowers or any other Person party to a Loan Document, and all applicable bank
regulatory laws relating to the transactions contemplated hereby, and made its own decision to
enter into this Agreement and to extend credit to Borrowers. Each Lender also represents that it
will, independently and without reliance upon any Agent-Related Person and based on such documents
and information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigations as it deems necessary to inform itself as
to the business, prospects, operations, property, financial and other condition and
creditworthiness of Borrowers or any other Person party to a Loan Document. Except for notices,
reports, and other documents expressly herein required to be furnished to the Lenders by Agent,
Agent shall not have any duty or responsibility to provide any Lender with any credit or other
information concerning the business, prospects, operations, property, financial and other condition
or creditworthiness of Borrowers or any other Person party to a Loan Document that may come into
the possession of any of Agent-Related Persons.

     15.7 Costs and Expenses; Indemnification. Agent may incur and pay Lender Group Expenses to
the extent Agent reasonably deems necessary or appropriate for the performance and fulfillment of
its functions, powers, and obligations pursuant to the Loan Documents, including court costs,
attorneys fees and expenses, fees and expenses of financial accountants, advisors, consultants, and
appraisers, costs of collection by outside collection agencies, auctioneer fees and expenses, and
costs of security guards or insurance premiums paid to maintain the Collateral, whether or not
Parent or its Subsidiaries are obligated to reimburse Agent or Lenders for such expenses pursuant
to this Agreement or otherwise. Agent is authorized and directed to deduct and retain sufficient
amounts from the Collections of Parent and its Subsidiaries received by Agent to reimburse Agent
for such out-of-pocket costs and expenses prior to the distribution of any amounts to Lenders. In
the event Agent is not reimbursed for such costs and expenses by Parent or its Subsidiaries, each
Lender hereby agrees that it is and shall be obligated to pay to Agent such Lender’s Pro Rata Share
thereof. Whether or not the transactions contemplated hereby are consummated, the Lenders shall
indemnify upon demand Agent-Related Persons (to the extent not reimbursed by or on behalf of
Borrowers and without limiting the obligation of Borrowers to do so), according to their Pro Rata
Shares, from and against any and all Indemnified Liabilities; provided, however, that no Lender
shall be liable for the payment to any Agent-Related Person of any portion of such Indemnified
Liabilities resulting solely from such Person’s gross negligence or willful misconduct nor shall
any Lender be liable for the obligations of any Defaulting Lender in failing to make an Advance or
other extension of credit hereunder. Without limitation of the foregoing, each Lender shall
reimburse Agent upon demand for such Lender’s Pro Rata Share of any costs or out of pocket expenses
(including attorneys, accountants, advisors, and consultants fees and expenses) incurred by Agent
in connection with the preparation, execution, delivery, administration, modification, amendment,
or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice
in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any
document contemplated by or referred to herein, to the extent that Agent is not reimbursed for such
expenses by or on behalf of Borrowers. The undertaking in this Section shall survive the payment
of all Obligations hereunder and the resignation or replacement of Agent.

     15.8 Agent in Individual Capacity. WFF and its Affiliates may make loans to, issue letters
of credit for the account of, accept deposits from, acquire equity interests in, and generally
engage in any

 - 64 - 

 

kind of banking, trust, financial advisory, underwriting, or other business with
Parent and its Subsidiaries and Affiliates and any other Person party to any Loan Documents as
though WFF were not Agent hereunder, and, in each case, without notice to or consent of the other
members of the Lender Group. The other members of the Lender Group acknowledge that, pursuant to
such activities, WFF or its Affiliates may receive information regarding Borrowers or their
Affiliates or any other Person party to any Loan Documents that is subject to confidentiality
obligations in favor of Borrowers or such other Person and that prohibit the disclosure of such
information to the Lenders, and the Lenders acknowledge that, in such circumstances (and in the
absence of a waiver of such confidentiality obligations, which waiver Agent will use its reasonable
best
efforts to obtain), Agent shall not be under any obligation to provide such information to them.
The terms “Lender” and “Lenders” include WFF in its individual capacity.

     15.9 Successor Agent. Agent may resign as Agent upon 45 days notice to the Lenders (unless
such notice is waived by the Required Lenders). If Agent resigns under this Agreement, the
Required Lenders shall appoint a successor Agent for the Lenders. If no successor Agent is
appointed prior to the effective date of the resignation or removal of Agent, Agent may appoint,
after consulting with the Lenders, a successor Agent. At any time, Agent may be removed upon prior
notice from the Required Lenders to Agent and the other Lenders. If Agent has been removed by the
Required Lenders, Required Lenders may agree in writing to replace Agent with a successor Agent
from among the Lenders. In any such event, upon the acceptance of its appointment as successor
Agent hereunder, such successor Agent shall succeed to all the rights, powers, and duties of the
retiring Agent and the term “Agent” shall mean such successor Agent and the retiring Agent’s
appointment, powers, and duties as Agent shall be terminated. After any retiring Agent’s
resignation hereunder as Agent, the provisions of this Section 15 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent under this
Agreement. If no successor Agent has accepted appointment as Agent by the date which is 45 days
following a retiring Agent’s notice of resignation, the retiring Agent’s resignation shall
nevertheless thereupon become effective and the Lenders shall perform all of the duties of Agent
hereunder until such time, if any, as the Lenders appoint a successor Agent as provided for above.

     15.10 Lender in Individual Capacity. Any Lender and its respective Affiliates may make
loans to, issue letters of credit for the account of, accept deposits from, acquire equity
interests in and generally engage in any kind of banking, trust, financial advisory, underwriting,
or other business with Parent and its Subsidiaries and Affiliates and any other Person party to any
Loan Documents as though such Lender were not a Lender hereunder without notice to or consent of
the other members of the Lender Group. The other members of the Lender Group acknowledge that,
pursuant to such activities, such Lender and its respective Affiliates may receive information
regarding Borrowers or their Affiliates or any other Person party to any Loan Documents that is
subject to confidentiality obligations in favor of Borrowers or such other Person and that prohibit
the disclosure of such information to the Lenders, and the Lenders acknowledge that, in such
circumstances (and in the absence of a waiver of such confidentiality obligations, which waiver
such Lender will use its reasonable best efforts to obtain), such Lender shall not be under any
obligation to provide such information to them.

15.11 Collateral Matters.

          (a) The Lenders hereby irrevocably authorize Agent, at its option and in its sole discretion,
to release any Lien on any Collateral (i) upon the termination of the Commitments and payment and
satisfaction in full by Borrowers of all Obligations (or, if the only remaining Obligations are
with respect to the Warrant, upon termination of all other Obligations), (ii) constituting property
being sold or disposed of if a release is required or desirable in connection therewith and if
Administrative Borrower certifies to Agent that the sale or disposition is permitted under
Section 6.4 of this Agreement or the other Loan Documents (and Agent may rely conclusively
on any such certificate, without further inquiry), (iii) constituting property in which neither
Parent nor any of its Subsidiaries owned any interest

 - 65 - 

 

at the time the Agent’s Lien was granted nor
at any time thereafter, or (iv) constituting property leased to Parent or any of its Subsidiaries
under a lease that has expired or is terminated in a transaction permitted
under this Agreement. Except as provided above, Agent will not execute and deliver a release
of any Lien on any Collateral without the prior written authorization of (y) if the release is of
all or substantially all of the Collateral, all of the Lenders, or (z) otherwise, the Required
Lenders. Upon request by Agent or Administrative Borrower at any time, the Lenders will confirm in
writing Agent’s authority to release any such Liens on particular types or items of Collateral
pursuant to this Section 15.11; provided, however, that (1) Agent shall not
be required to execute any document necessary to evidence such release on terms that, in Agent’s
opinion, would expose Agent to liability or create any obligation or entail any consequence other
than the release of such Lien without recourse, representation, or warranty, and (2) such release
shall not in any manner discharge, affect, or impair the Obligations or any Liens (other than those
expressly being released) upon (or obligations of Borrowers in respect of) all interests retained
by Borrowers, including, the proceeds of any sale, all of which shall continue to constitute part
of the Collateral.

          (b) Agent shall have no obligation whatsoever to any of the Lenders to assure that the
Collateral exists or is owned by Parent or any of its Subsidiaries or is cared for, protected, or
insured or has been encumbered, or that the Agent’s Liens have been properly or sufficiently or
lawfully created, perfected, protected, or enforced or are entitled to any particular priority, or
to exercise at all or in any particular manner or under any duty of care, disclosure or fidelity,
or to continue exercising, any of the rights, authorities and powers granted or available to Agent
pursuant to any of the Loan Documents, it being understood and agreed that in respect of the
Collateral, or any act, omission, or event related thereto, subject to the terms and conditions
contained herein, Agent may act in any manner it may deem appropriate, in its sole discretion given
Agent’s own interest in the Collateral in its capacity as one of the Lenders and that Agent shall
have no other duty or liability whatsoever to any Lender as to any of the foregoing, except as
otherwise provided herein.

     15.12 Restrictions on Actions by Lenders; Sharing of Payments.

          (a) Each of the Lenders agrees that it shall not, without the express written consent of
Agent, and that it shall, to the extent it is lawfully entitled to do so, upon the written request
of Agent, set off against the Obligations, any amounts owing by such Lender to Parent or any of its
Subsidiaries or any deposit accounts of Parent or any of its Subsidiaries now or hereafter
maintained with such Lender. Each of the Lenders further agrees that it shall not, unless
specifically requested to do so in writing by Agent, take or cause to be taken any action,
including, the commencement of any legal or equitable proceedings to enforce any Loan Document
against the Borrowers or Guarantors or to foreclose any Lien on, or otherwise enforce any security
interest in, any of the Collateral.

          (b) If, at any time or times any Lender shall receive (i) by payment, foreclosure, setoff, or
otherwise, any proceeds of Collateral or any payments with respect to the Obligations, except for
any such proceeds or payments received by such Lender from Agent pursuant to the terms of this
Agreement, or (ii) payments from Agent in excess of such Lender’s Pro Rata Share of all such
distributions by Agent, such Lender promptly shall (A) turn the same over to Agent, in kind, and
with such endorsements as may be required to negotiate the same to Agent, or in immediately
available funds, as applicable, for the account of all of the Lenders and for application to the
Obligations in accordance with the applicable provisions of this Agreement, or (B) purchase,
without recourse or warranty, an undivided interest and participation in the Obligations owed to
the other Lenders so that such excess payment received shall be applied ratably as among the
Lenders in accordance with their Pro Rata Shares; provided, however, that to the
extent that such excess payment received by the purchasing party is thereafter recovered from it,
those purchases of participations shall be rescinded in whole or in part, as applicable, and the
applicable portion of the purchase price paid therefor shall be returned to such

 - 66 - 

 

purchasing party, but without interest except to the extent that such purchasing party is
required to pay interest in connection with the recovery of the excess payment.

     15.13 Agency for Perfection. Agent hereby appoints each other Lender as its agent (and
each Lender hereby accepts such appointment) for the purpose of perfecting Agent’s Liens in assets
which, in accordance with Article 8 or Article 9, as applicable, of the Code can be perfected only
by possession or control. Should any Lender obtain possession or control of any such Collateral,
such Lender shall notify Agent thereof, and, promptly upon Agent’s request therefor shall deliver
possession or control of such Collateral to Agent or in accordance with Agent’s instructions.

     15.14 Payments by Agent to the Lenders. All payments to be made by Agent to the Lenders
shall be made by bank wire transfer of immediately available funds pursuant to such wire transfer
instructions as each party may designate for itself by written notice to Agent. Concurrently with
each such payment, Agent shall identify whether such payment (or any portion thereof) represents
principal, premium, fees, or interest of the Obligations.

     15.15 Concerning the Collateral and Related Loan Documents. Each member of the Lender
Group authorizes and directs Agent to enter into this Agreement and the other Loan Documents. Each
member of the Lender Group agrees that any action taken by Agent in accordance with the terms of
this Agreement or the other Loan Documents relating to the Collateral and the exercise by Agent of
its powers set forth therein or herein, together with such other powers that are reasonably
incidental thereto, shall be binding upon all of the Lenders.

     15.16 Field Audits and Examination Reports; Confidentiality; Disclaimers by Lenders; Other
Reports and Information. By becoming a party to this Agreement, each Lender:

          (a) is deemed to have requested that Agent furnish such Lender, promptly after it becomes
available, a copy of each field audit or examination report respecting Parent and its Subsidiaries
(each a “Report” and collectively, “Reports”) prepared by or at the request of
Agent, and Agent shall so furnish each Lender with such Reports,

          (b) expressly agrees and acknowledges that Agent does not (i) make any representation or
warranty as to the accuracy of any Report, and (ii) shall not be liable for any information
contained in any Report,

          (c) expressly agrees and acknowledges that the Reports are not comprehensive audits or
examinations, that Agent or other party performing any audit or examination will inspect only
specific information regarding Parent and its Subsidiaries and will rely significantly upon Parent
and its Subsidiaries’ books and records, as well as on representations of Borrowers’ personnel,

          (d) agrees to keep all Reports and other material, non-public information regarding Parent and
its Subsidiaries and their operations, assets, and existing and contemplated business plans in a
confidential manner in accordance with Section 17.9, and

          (e) without limiting the generality of any other indemnification provision contained in this
Agreement, agrees: (i) to hold Agent and any other Lender preparing a Report harmless
from any action the indemnifying Lender may take or fail to take or any conclusion the
indemnifying Lender may reach or draw from any Report in connection with any loans or other credit
accommodations that the indemnifying Lender has made or may make to Borrowers, or the indemnifying
Lender’s participation in, or the indemnifying Lender’s purchase of, a loan or loans of Borrowers,
and (ii) to pay and protect, and indemnify, defend and hold Agent, and any such other Lender
preparing a Report

 - 67 - 

 

harmless from and against, the claims, actions, proceedings, damages, costs,
expenses, and other amounts (including, attorneys fees and costs) incurred by Agent and any such
other Lender preparing a Report as the direct or indirect result of any third parties who might
obtain all or part of any Report through the indemnifying Lender.

In addition to the foregoing: (x) any Lender may from time to time request of Agent in writing that
Agent provide to such Lender a copy of any report or document provided by Parent or any of its
Subsidiaries to Agent that has not been contemporaneously provided by Parent or any of its
Subsidiaries to such Lender, and, upon receipt of such request, Agent promptly shall provide a copy
of same to such Lender, (y) to the extent that Agent is entitled, under any provision of the Loan
Documents, to request additional reports or information from Parent or any of its Subsidiaries, any
Lender may, from time to time, reasonably request Agent to exercise such right as specified in such
Lender’s notice to Agent, whereupon Agent promptly shall request of Administrative Borrower the
additional reports or information reasonably specified by such Lender, and, upon receipt thereof
from Administrative Borrower, Agent promptly shall provide a copy of same to such Lender, and (z)
any time that Agent renders to Administrative Borrower a statement regarding the Loan Account,
Agent shall send a copy of such statement to each Lender.

     15.17 Several Obligations; No Liability. Notwithstanding that certain of the Loan
Documents now or hereafter may have been or will be executed only by or in favor of Agent in its
capacity as such, and not by or in favor of the Lenders, any and all obligations on the part of
Agent (if any) to make any credit available hereunder shall constitute the several (and not joint)
obligations of the respective Lenders on a ratable basis, according to their respective
Commitments, to make an amount of such credit not to exceed, in principal amount, at any one time
outstanding, the amount of their respective Commitments. Nothing contained herein shall confer
upon any Lender any interest in, or subject any Lender to any liability for, or in respect of, the
business, assets, profits, losses, or liabilities of any other Lender. Each Lender shall be solely
responsible for notifying its Participants of any matters relating to the Loan Documents to the
extent any such notice may be required, and no Lender shall have any obligation, duty, or liability
to any Participant of any other Lender. Except as provided in Section 15.7, no member of
the Lender Group shall have any liability for the acts of any other member of the Lender Group. No
Lender shall be responsible to any Borrower or any other Person for any failure by any other Lender
to fulfill its obligations to make credit available hereunder, nor to advance for it or on its
behalf in connection with its Commitment, nor to take any other action on its behalf hereunder or
in connection with the financing contemplated herein.

16. WITHHOLDING TAXES.

          (a) All payments made by any Borrower hereunder or under any note or other Loan Document will
be made without setoff, counterclaim, or other defense. In addition, all such payments will be
made free and clear of, and without deduction or withholding for, any present or future Indemnified
Taxes and Other Taxes, and in the event any deduction or withholding of Indemnified Taxes and Other
Taxes is required, each Borrower shall comply with the penultimate sentence of this Section
16(a). If any Indemnified Taxes and Other Taxes are so levied or imposed, each Borrower agrees
to pay the full amount of such Indemnified Taxes and Other Taxes and such additional amounts as may
be necessary so that every payment of all amounts due under this Agreement, any note, or Loan
Document, including any amount paid pursuant to this Section 16(a) after withholding or
deduction for or on account
of any Indemnified Taxes and Other Taxes, will not be less than the amount provided for
herein; provided, however, that Borrowers shall not be required to increase any such amounts if the
increase in such amount payable results from Agent’s or such Lender’s own willful misconduct or
gross negligence (as finally determined by a court of competent jurisdiction). Each Borrower will
furnish to Agent as promptly as possible after the date the payment of any Indemnified Tax and
Other Tax is due pursuant to applicable law certified copies of tax receipts evidencing such
payment by Borrower.

 - 68 - 

 

          (b) If a Lender claims an exemption from United States withholding tax, Lender agrees with and
in favor of Agent and any Borrower, to deliver to Agent:

                    (i) if such Lender claims an exemption from United States withholding tax pursuant to its
portfolio interest exception, (A) a statement of the Lender, signed under penalty of perjury, that
it is not a (I) a “bank” as described in Section 881(c)(3)(A) of the IRC, (II) a 10% shareholder of
any Borrower (within the meaning of Section 871(h)(3)(B) of the IRC), or (III) a controlled foreign
corporation related to any Borrower within the meaning of Section 864(d)(4) of the IRC, and (B) a
properly completed and executed IRS Form W-8BEN, before receiving its first payment under this
Agreement and at any other time reasonably requested by Agent or any Borrower;

                    (ii) if such Lender claims an exemption from, or a reduction of, withholding tax under a
United States tax treaty, properly completed and executed IRS Form W-8BEN before receiving its
first payment under this Agreement and at any other time reasonably requested by Agent or any
Borrower;

                    (iii) if such Lender claims that interest paid under this Agreement is exempt from United
States withholding tax because it is effectively connected with a United States trade or business
of such Lender, two properly completed and executed copies of IRS Form W-8ECI before receiving its
first payment under this Agreement and at any other time reasonably requested by Agent or any
Borrower; or

                    (iv) such other form or forms, including IRS Form W-9, as may be required under the IRC or
other laws of the United States as a condition to exemption from, or reduction of, United States
withholding or backup withholding tax before receiving its first payment under this Agreement and
at any other time reasonably requested by Agent or any Borrower.

Lender agrees promptly to notify Agent and Administrative Borrower of any change in circumstances
which would modify or render invalid any claimed exemption or reduction. In addition, each such
Lender agrees that it will deliver, upon Administrative Borrower’s written request, updated
versions of the foregoing documents whenever they have become obsolete or inaccurate in any
material respect, together with such other forms or documents as may be required in order to
confirm or establish the entitlement of such Lender to continued exemption from or reduction of
withholding tax, but only if, and to the extent that, such Lender is eligible for such exemption or
reduction.

          (c) If a Lender claims an exemption from withholding tax in a jurisdiction other than the
United States, Lender agrees with and in favor of Agent and Borrowers, to deliver to Agent any such
form or forms, as may be required under the laws of such jurisdiction as a condition to exemption
from, or reduction of, foreign withholding or backup withholding tax before receiving its first
payment under this Agreement and at any other time reasonably requested by Agent or Administrative
Borrower.

Lender agrees promptly to notify Agent and Administrative Borrower of any change in circumstances
which would modify or render invalid any claimed exemption or reduction.

          (d) If any Lender claims exemption from, or reduction of, withholding tax and such Lender
sells, assigns, grants a participation in, or otherwise transfers all or part of the Obligations of
Borrowers to such Lender, such Lender agrees to notify Agent and Administrative Borrower of the
percentage amount in which it is no longer the beneficial owner of Obligations of Borrowers to such
Lender. To the extent of such percentage amount, Agent and Borrowers will treat such Lender’s
documentation provided pursuant to Sections 16(b) or 16(c) as no longer valid. With
respect to such

 - 69 - 

 

percentage amount, Lender may provide new documentation, pursuant to Sections
16(b) or 16(c), if applicable.

          (e) If any Lender is entitled to a reduction in the applicable withholding tax, Agent may
withhold from any interest payment to such Lender an amount equivalent to the applicable
withholding tax after taking into account such reduction. If the forms or other documentation
required by subsection (b) or (c) of this Section 16 are not delivered to Agent,
then Agent may withhold from any interest payment to such Lender not providing such forms or other
documentation an amount equivalent to the applicable withholding tax.

          (f) If the IRS or any other Governmental Authority of the United States or other jurisdiction
asserts a claim that Agent did not properly withhold tax from amounts paid to or for the account of
any Lender due to a failure on the part of the Lender (because the appropriate form was not
delivered, was not properly executed, or because such Lender failed to notify Agent of a change in
circumstances which rendered the exemption from, or reduction of, withholding tax ineffective, or
for any other reason) such Lender shall indemnify and hold Agent harmless for all amounts paid,
directly or indirectly, by Agent, as tax or otherwise, including penalties and interest, and
including any taxes imposed by any jurisdiction on the amounts payable to Agent under this
Section 16, together with all costs and expenses (including attorneys fees and expenses).
The obligation of the Lenders under this subsection shall survive the payment of all Obligations
and the resignation or replacement of Agent.

          (g) If Agent or a Lender determines, in its sole discretion, that it has received a refund of
any Indemnified Taxes or Other Taxes as to which it has been indemnified by a Borrower or with
respect to which a Borrower paid additional amounts pursuant to this Section 16, it shall
pay over such refund to such Borrower (but only to the extent of indemnity payments made, or
additional amounts paid, by such Borrower under this Section 16 with respect to the
Indemnified Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of
Agent or such Lender and without interest (other than any interest paid by the relevant
governmental authority with respect to such refund); provided, that the amount paid over to
such Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental
Authority) shall be repaid to Agent or such Lender by such Borrower in the event that Agent or such
Lender is required to repay such refund to such governmental authority. This section shall not be
construed to require Agent or any Lender to make available its tax returns (or any other
information relating to its taxes which it deems confidential) to any Borrower or any other Person.

17. GENERAL PROVISIONS.

purposes and intentions of all parties hereto.

 - 70 - 

 

     17.4 Severability of Provisions. Each provision of this Agreement shall be severable from
every other provision of this Agreement for the purpose of determining the legal enforceability of
any specific provision.

     17.5 Bank Product Providers. Each Bank Product Provider shall be deemed a party hereto for
purposes of any reference in a Loan Document to the parties for whom Agent is acting; it being
understood and agreed that the rights and benefits of such Bank Product Provider under the Loan
Documents consist exclusively of such Bank Product Provider’s right to share in payments and
collections out of the Collateral as more fully set forth herein. In connection with any such
distribution of payments and collections, Agent shall be entitled to assume no amounts are due to
any Bank Product Provider unless such Bank Product Provider has notified Agent in writing of the
amount of any such liability owed to it prior to such distribution.

     17.6 Lender-Creditor Relationship. The relationship between the Lenders and Agent, on the
one hand, and Borrowers, on the other hand, is solely that of creditor and debtor. No member of
the Lender Group has (or shall be deemed to have) any fiduciary relationship or duty to Borrowers
arising out of or in connection with, and there is no agency or joint venture relationship between
the members of the Lender Group, on the one hand, and Borrowers, on the other hand, by virtue of
any Loan Document or any transaction contemplated therein.

     17.7 Counterparts; Electronic Execution. This Agreement may be executed in any number of
counterparts and by different parties on separate counterparts, each of which, when executed and
delivered, shall be deemed to be an original, and all of which, when taken together, shall
constitute but one and the same Agreement. Delivery of an executed counterpart of this Agreement
by telefacsimile or other electronic method of transmission shall be equally as effective as
delivery of an original executed counterpart of this Agreement. Any party delivering an executed
counterpart of this Agreement by telefacsimile or other electronic method of transmission also
shall deliver an original executed counterpart of this Agreement but the failure to deliver an
original executed counterpart shall not affect the validity, enforceability, and binding effect of
this Agreement. The foregoing shall apply to each other Loan Document mutatis mutandis.

     17.8 Revival and Reinstatement of Obligations. If the incurrence or payment of the
Obligations by any Borrower or Guarantor or the transfer to the Lender Group of any property should
for any reason subsequently be declared to be void or voidable under any state or federal law
relating to creditors’ rights, including provisions of the Bankruptcy Code relating to fraudulent
conveyances, preferences, or other voidable or recoverable payments of money or transfers of
property (each, a “Voidable Transfer”), and if the Lender Group is required to repay or
restore, in whole or in part, any such Voidable Transfer, or elects to do so upon the reasonable
advice of
its counsel, then, as to any such Voidable Transfer, or the amount thereof that the Lender Group is
required or elects to repay or restore, and as to all reasonable costs, expenses, and attorneys
fees of the Lender Group related thereto, the liability of Borrowers or Guarantors automatically
shall be revived, reinstated, and restored and shall exist as though such Voidable Transfer had
never been made.

17.9 Confidentiality.

          (a) Agent and Lenders each individually (and not jointly or jointly and severally) agree that
material, non-public information regarding Parent or any of its Subsidiaries, their operations,
assets, and existing and contemplated business plans shall be treated by Agent and the Lenders in a
confidential manner, and shall not be disclosed by Agent and the Lenders to Persons who are not
parties to this Agreement, except: (i) to attorneys for and other advisors, accountants, auditors,
and consultants to any member of the Lender Group, (ii) to Subsidiaries and Affiliates of any
member of the Lender

 - 71 - 

 

Group (including the Bank Product Providers), provided that any such
Subsidiary or Affiliate shall have agreed to receive such information hereunder subject to the
terms of this Section 17.9, (iii) as may be required by statute, decision, or judicial or
administrative order, rule, or regulation, (iv) as may be agreed to in advance by Administrative
Borrower or its Subsidiaries or as requested or required by any Governmental Authority pursuant to
any subpoena or other legal process, (v) as to any such information that is or becomes generally
available to the public (other than as a result of prohibited disclosure by Agent or the Lenders),
(vi) in connection with any assignment, prospective assignment, sale, prospective sale,
participation, prospective participation or pledge or prospective or pledge of any Lender’s
interest under this Agreement, provided that any such assignee, prospective assignment, sale,
prospective sale, participation, prospective participation or pledge or prospective or pledgee
shall have agreed in writing to receive such information hereunder subject to the terms of this
Section, and (vii) in connection with any litigation or other adversary proceeding involving
parties hereto which such litigation or adversary proceeding involves claims related to the rights
or duties of such parties under this Agreement or the other Loan Documents. The provisions of this
Section 17.9(a) shall survive for 2 years after the payment in full of the Obligations.

          (b) Anything in this Agreement to the contrary notwithstanding, Agent may provide information
concerning the terms and conditions of this Agreement and the other Loan Documents to loan
syndication and pricing reporting services.

     17.10 Lender Group Expenses. Borrowers agree to pay any and all Lender Group Expenses
promptly after demand therefor by Agent or any Lender and agree that their obligations contained in
this Section 17.10 shall survive payment or satisfaction in full of all other Obligations.

     17.11 USA PATRIOT Act. Each Lender that is subject to the requirements of the USA Patriot
Act (Title 111 of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”) hereby notifies
Borrowers that pursuant to the requirements of the Act, it is required to obtain, verify and record
information that identifies Borrowers, which information includes the name and address of Borrowers
and other information that will allow such Lender to identify Borrowers in accordance with the Act.

     17.12 Integration. This Agreement, together with the other Loan Documents, reflects the
entire understanding of the parties with respect to the transactions contemplated hereby and shall
not be contradicted or qualified by any other agreement, oral or written, before the date hereof.

     17.13 Parent as Agent for Borrowers. Each Borrower hereby irrevocably appoints Parent as
the borrowing agent and attorney-in-fact for all Borrowers (the “Administrative Borrower”)
which appointment shall remain in full force and effect unless and until Agent shall have received
prior written notice signed by each Borrower that such appointment has been revoked and that
another Borrower has been appointed Administrative Borrower. Each Borrower hereby irrevocably
appoints and authorizes the Administrative Borrower (i) to provide Agent with all notices with
respect to Advances and Letters of Credit obtained for the benefit of any Borrower and all other
notices and instructions under this Agreement and (ii) to take such action as the Administrative
Borrower deems appropriate on its behalf to obtain Advances and Letters of Credit and to exercise
such other powers as are reasonably incidental thereto to carry out the purposes of this Agreement.
It is understood that the handling of the Loan Account and Collateral of Borrowers in a combined
fashion, as more fully set forth herein, is done solely as an accommodation to Borrowers in order
to utilize the collective borrowing powers of Borrowers in the most efficient and economical manner
and at their request, and that Lender Group shall not incur liability to any Borrower as a result
hereof. Each Borrower expects to derive benefit, directly or indirectly, from the handling of the
Loan Account and the Collateral in a combined fashion since the successful operation of each
Borrower is dependent on the continued successful performance of the integrated group. To induce
the Lender Group to do so, and in consideration thereof, each Borrower hereby jointly and

 - 72 - 

 

severally
agrees to indemnify each member of the Lender Group and hold each member of the Lender Group
harmless against any and all liability, expense, loss or claim of damage or injury, made against
the Lender Group by any Borrower or by any third party whosoever, arising from or incurred by
reason of (a) the handling of the Loan Account and Collateral of Borrowers as herein provided, (b)
the Lender Group’s relying on any instructions of the Administrative Borrower, or (c) any other
action taken by the Lender Group hereunder or under the other Loan Documents, except that Borrowers
will have no liability to the relevant Agent-Related Person or Lender-Related Person under this
Section 17.13 with respect to any liability that has been finally determined by a court of
competent jurisdiction to have resulted solely from the gross negligence or willful misconduct of
such Agent-Related Person or Lender-Related Person, as the case may be.
