     Section 6. Conversion, Redemption and Other Rights.

          (a) The Series B is not convertible into any other class or series of the capital stock of the
Corporation or into cash, property or other rights, and no share of Series B may be redeemed prior
to its applicable Redeemable Date.

          (b) On and from time to time after each Redeemable Date, the Corporation may, at its option,
redeem, in whole or in part, the then-outstanding shares of Series B issued on a date on or prior
to the date that is ninety (90) months before such Redeemable Date, at a redemption price per share

redemption have been deposited by the Corporation, in trust for the pro rata benefit of the holders
of the shares called for redemption, with a bank or trust company doing business in the Borough of
Manhattan, The City of New York, so as to be and continue to be available solely therefor, then,
notwithstanding that any certificate for any share so called for redemption has not been
surrendered for cancellation, on and after the applicable redemption date all shares so called for
redemption shall no longer be deemed outstanding and all rights with respect to such shares shall
forthwith on the applicable redemption date cease and terminate, except only the right of the
holders thereof to receive the redemption price payable on such redemption from such bank or trust
company, without interest. Any funds or shares of Common Stock unclaimed at the end of ninety days
from the applicable redemption date shall, to the extent permitted by law, be released to the
Corporation, after which time the holders of the shares so called for redemption shall look only to
the Corporation for payment of the redemption price of such shares.

     Section 7. Transfer; Surrender Upon Exercise of Warrants. Each Fractional Share of Series B
shall be issued as a unit with a Warrant, or portion thereof, representing the right to purchase
one share of Common Stock and may only be sold or otherwise transferred concurrently with the sale
of such Warrant. Any sale or transfer, or purported sale or transfer, of shares or Fractional
Shares of Series B shall be null and void, and the Corporation shall have no obligation to effect
any transfer, unless the foregoing transfer restrictions are strictly observed. In the event that a
holder of Series B exercises its right to acquire Common Stock of the Corporation pursuant to a
Warrant, such holder shall surrender to the Corporation a number of Fractional Shares of Series B
of such holder equal to the number of shares of Common Stock purchased upon exercise of such
Warrant. In no event shall the Corporation issue any shares of Series B, or Fractional Shares,
other than in connection with the issuance of Warrants pursuant to and in accordance with the
Purchase Agreement and otherwise in connection with such Warrants.

     Section 8. Voting Rights.

          (a) Each full share of Series B shall be entitled to 100 votes, with each Fractional Share

3

 

being entitled to one vote. So long as any shares of Series B are outstanding, in addition to any
other vote or consent of stockholders required by law or by the Certificate of Incorporation, the
holders of Series B shall be entitled to vote in the election of directors and on all other matters
submitted to a vote of the holders of Common Stock of the Corporation, with the Series B and Common
Stock voting together as a single class; provided, however, that (i) until December 31, 2011, the
holders of Series B and their affiliates shall not be entitled, with respect to all shares,
including Fractional Shares, of Series B and other Voting Stock owned by them, to more votes than
the number equal to the product of (A) 45 and (B) the quotient obtained by dividing (x) the number
of votes all other holders of Voting Stock are entitled to by (y) 55, and (ii) after December 31,
2011, the holders of Series B and their affiliates shall not be entitled, solely with respect to
all shares, including Fractional Shares, of Series B owned by them, to more votes than the number
equal to the product of (A) 45 and (B) the quotient obtained by dividing (x) the number of votes
all other Voting Stock (including such Voting Stock owned by the holders of Series B and their
affiliates) is entitled to by (y) 55. If more than one person holds Series B, then the voting
rights of such persons shall be reduced pro rata according to their ownership percentages in order
to comply with this limitation. Any share, including any Fractional Share, of Series B and, if
applicable, other Voting Stock with respect to which the holders of Series B and their affiliates
are not entitled to vote pursuant to the limitations in this Section 8(a), shall not be considered,
in determining whether a quorum is present at any meeting of stockholders of the Corporation, as
outstanding shares of capital stock entitled to vote at such meeting.

          (b) So long as any shares of Series B are outstanding, in addition to any other vote or
consent of stockholders required by law or by the Certificate of Incorporation, the vote or
consent of the holders of a majority of the shares of Series B at the time outstanding and
entitled to vote thereon, given in person or by proxy, either in writing without a meeting or by
vote at any meeting called for the purpose, shall be necessary for effecting or validating:

               (i) Any amendment, alteration or repeal of any provision of the Certificate of Incorporation
so as to change the rights, preferences, privileges or voting powers of the Series B;

               (ii) Any amendment or alteration of the Certificate of Incorporation to authorize or create,
or increase or decrease the authorized amount of, any shares of Series B;

               (iii) Any amendment, alteration or repeal of any provision of the Certificate of
Incorporation or Bylaws so as to materially and adversely affect the special rights, preferences,
privileges or voting powers of the Series B.

Notwithstanding anything herein to the contrary, in no event shall any holder of full shares or
Fractional Shares of Series B be entitled to (i) vote on any matter on which the Series B is
entitled to vote unless such holder shall also be the record holder of the corresponding Warrant
that is part of the unit with such shares or Fractional Shares and (ii) cast a number of votes in
excess of the number of shares purchasable upon exercise of the Warrants of which such holder is
the record holder. Furthermore, except as provided by law, no share or Fractional Share of Series
B shall have any voting rights following the Redeemable Date for such share.

     Section 9. Record Holders. To the fullest extent permitted by applicable law, the
Corporation may deem and treat the record holder of any share of Series B as the true and lawful

4

 

owner thereof for all purposes, and the Corporation shall not be affected by any notice to the
contrary.

     Section 10. Notices. All notices or communications in respect of Series B shall be
sufficiently given if given in writing and delivered in person or by fax, overnight or certified
mail, or if given in such other manner as may be permitted in this Certificate of Designations, in
the Certificate of Incorporation or Bylaws or by applicable law.

     Section 11. No Preemptive Rights. No share of Series B shall have any rights of preemption
whatsoever as to any securities of the Corporation, or any warrants, rights or options issued or
granted with respect thereto, regardless of how such securities, or such warrants, rights or
options, may be designated, issued or granted.

     Section 12. Replacement Certificates. The Corporation shall replace any mutilated certificate
at the holder’s expense upon surrender of that certificate to the Corporation. The Corporation
shall replace certificates that become destroyed, stolen or lost at the holder’s expense upon
delivery to the Corporation of reasonably satisfactory evidence that the certificate has been
destroyed, stolen or lost, together with any indemnity that may be reasonably required by the
Corporation.

     Section 13. Other Rights. The shares of Series B shall not have any rights, preferences,
privileges or voting powers or relative, participating, optional or other special rights, or
qualifications, limitations or restrictions thereof, other than as set forth herein or in the
Certificate of Incorporation or as provided by applicable law.

2. REGISTRATION RIGHTS

     (a) Mandatory Resale Registration.

     (i) At any time on or after the date that is 90 days after the Closing Date, upon the
written request (a “Notice”) of any Stockholder or Stockholders holding individually
or collectively at least a majority of the then outstanding Registrable Securities, the
Corporation shall file under the Securities Act, within 30 days after receiving such Notice,
a registration statement on an appropriate form providing for the resale of any Registrable
Securities pursuant to Rule 415 from time to time by the Holders (a “Resale Registration
Statement”). The Company shall use its commercially reasonable efforts to cause such
Resale Registration Statement to be declared effective by the Commission within 120 days
after the the filing thereof, provided that sales pursuant to the Resale Registration
Statement shall be subject to the restrictions in Section 2(c)(iv) to the extent applicable.
Any Resale Registration Statement shall provide for the resale from time to time, and
pursuant to any method or combination of methods legally available by the Holders of any and
all Registrable Securities. Subject to the other provisions of this Agreement, the
Corporation shall cause the Resale Registration Statement filed pursuant to this Section
2(a)(i) to be continuously effective, supplemented and amended to the extent necessary to
ensure that it is available for the resale of all Registrable Securities by the Holders and
that it conforms in all material respects to the requirements of the Securities Act during
the entire period beginning on the date the Resale Registration Statement is first declared
effective under the Securities Act and ending on the date on which all Registrable
Securities have ceased to be Registrable Securities (the “Effectiveness Period”).

     (ii) Amendment on Form S-3 to Registration Statement on Form S-1. If the
Resale Registration Statement filed pursuant to Section 2(a)(i) is on Form S-1, the
Corporation may, at any time it is eligible to do so, file a post-effective amendment on
Form S-3 to the Resale Registration Statement on Form S-1 for the resale of any then
existing Registrable Securities or in any such other manner as is preferred or permitted by
the Commission to convert the Resale Registration Statement on Form S-1 to a Resale
Registration Statement on Form S-3. Upon the effectiveness of the Resale Registration
Statement on Form S-3, all references to the Resale Registration Statement in this Agreement
shall then automatically be deemed to be a reference to the Resale Registration Statement on
Form S-3.

     (b) Delay in Filing or Effectiveness of Resale Registration Statement.

     (i) If the Company fails to file the Resale Registration Statement with the Commission
within the period specified in Section 2(a)(i), then each Holder will be entitled to a
payment, as liquidated damages and not a penalty, of the Liquidated

5

 

Damages Amount but only with respect to shares of Common Stock or Common Stock
underlying the Warrants then held by such Holder and not included in an effective
Registration Statement, for a period beginning on the day after the deadline for filing the
Resale Registration Statement and lasting until such time as the Resale Registration
Statement is filed.

     (ii) If the Resale Registration Statement does not become or is not declared effective
within the period specified in Section 2(a)(i), then each Holder will be entitled to a
payment, as liquidated damages and not a penalty, of the Liquidated Damages Amount but only
with respect to shares of Common Stock or Common Stock underlying the Warrants then held by
such Holder and not included in an effective Registration Statement, for the period
beginning on the day after such deadline for effectiveness of the Resale Registration
Statement and lasting until such time as the Resale Registration Statement is declared
effective.

     (iii) The aggregate Liquidated Damages Amount payable to each Holder shall be paid to
each Holder in immediately available funds within 10 Business Days after the end of each
applicable 30-day period. Any payments pursuant to this Section 2(b) shall constitute the
Holders’ exclusive remedy for such events; provided, however, if the Corporation certifies
that it is unable to pay aggregate Liquidated Damages Amount in cash or immediately
available funds because such payment would result in a breach under any of the Corporation’s
credit facilities or other indebtedness filed as exhibits to the Corporation’s reports filed
under the Securities Act or the Exchange Act, then the Corporation may pay the aggregate
Liquidated Damages Amount in kind in the form of the issuance of additional shares of Common
Stock. Upon any issuance of shares of Common Stock as liquidated damages, the Corporation
shall promptly prepare and file an amendment to the Resale Registration Statement prior to
its effectiveness to include such shares of Common Stock issued as liquidated damages as
additional Registrable Securities. If shares of Common Stock are issued as liquidated
damages after the Resale Registration Statement has been declared effective, the Corporation
shall have no obligation to prepare and file a post-effective amendment to the Resale
Registration Statement to include such shares nor shall the Corporation be obligated in any
way to file a new registration statement for such shares; however if the Corporation is a
well-known seasoned issuer (as defined in the rules and regulations of the Commission)
(“WKSI”), the Corporation shall be obligated to provide the Holder notice and offer
to include such shares in any Piggyback Registration Statement. All shares of Common Stock
issued as Liquidated Damages Amounts shall be considered in the calculation of any
subsequent Liquidated Damages Amounts. The determination of the number of shares of Common
Stock to be issued as the aggregate Liquidated Damages Amount shall be equal to the
aggregate Liquidated Damages Amount divided by the average of the closing sale price per
share for the Common Stock (or if the Common Stock is not listed or traded on a national
securities exchange, the average of the last reported bid and ask prices per share) for each
of the 10 consecutive trading days ending on the trading day immediately preceding such date
of determination.

     (c) Public Offering.

6

 

     (i) If the Corporation proposes to file

(A) a registration statement on Form S-1, or such other form under the Securities
Act, providing for the public offering of Common Stock, for its own account or for
the account of a selling stockholder, for sale to the public in an Underwritten
Offering, excluding the Resale Registration Statement, a registration statement on
Form S-4 or Form S-8 promulgated under the Securities Act (or any successor forms
thereto), a registration statement for the sale of Common Stock issued upon
conversion of debt securities or any other form not available for registering the
Registrable Securities for sale to the public, or

(B) a prospectus supplement to an effective shelf Registration Statement, so long as
the Corporation is a well-known seasoned issuer (as defined in the rules and
regulations of the Commission) (“WKSI”) at such time or, whether or not the
Corporation is a WKSI, so long as the Registrable Securities were previously
included in the underlying shelf Registration Statement or are included on an
effective Resale Registration Statement,

then, in each case with respect to an Underwritten Offering of Common Stock, the Corporation
will notify each Holder of the proposed filing and afford each Holder an opportunity to
include in such Registration Statement (the “Piggyback Registration Statement”) all
or any part of the shares of Common Stock that constitute Registrable Securities then held
by such Holder that may properly be offered on such Piggyback Registration Statement. Each
Holder desiring to include in the Piggyback Registration Statement all or part of such
shares of Common Stock held by such Holder that may be included in the Piggyback
Registration Statement shall, within ten (10) days after receipt of the above-described
notice from the Corporation in the case of a filing of a Registration Statement and within
two (2) Business Days after the day of receipt of the above-described notice from the
Corporation in the case of a filing of a prospectus supplement to an effective shelf
Piggyback Registration Statement with respect to an Underwritten Offering, so notify the
Corporation in writing, and in such notice shall inform the Corporation of the number of
shares of Common Stock such Holder wishes to include in the Piggyback Registration Statement
and provide the Corporation with such information with respect to such Holder as shall be
reasonably necessary in order to assure compliance with federal and applicable state
securities laws. Any election by any Holder to include any shares of Common Stock that
constitute Registrable Securities in the Piggyback Registration Statement will not affect
the inclusion of such Registrable Securities in the Resale Registration Statement until such
Registrable Securities have been sold under the Piggyback Registration Statement.

     (ii) Right to Terminate Registration. The Corporation shall have the right, in
its sole discretion, to terminate or withdraw the Piggyback Registration Statement initiated
by it referred to in this Section 2(b) prior to the effectiveness of such registration (or
pricing in the event of an Underwritten Offering pursuant to an effective shelf Registration
Statement) whether or not any Holder has elected to include Registrable Securities in such
registration.

7

 

     (iii) Resale Registration not Impacted by Piggyback Registration Statement.
The Corporation’s obligation to file the Resale Registration Statement pursuant to Section
2(a)(i) shall not be affected by the filing or effectiveness of the Piggyback Registration
Statement.

     (d) Underwriting.

     (i) Resale Registration. In the event that one or more Holders elect to dispose
of shares of Common Stock that constitute Registrable Securities under the Resale
Registration Statement pursuant to an Underwritten Offering and such Holders reasonably
anticipate gross proceeds from such Underwritten Offering of at least $20,000,000, in the
aggregate, the Corporation shall take all such reasonable actions as are requested by the
managing underwriter in order to expedite and facilitate the registration and disposition of
such shares of Common Stock, including the Corporation causing appropriate officers of the
Corporation or its Affiliates to participate in a “road show” or similar marketing effort
being conducted by such managing underwriter with respect to such Underwritten Offering,
provided that the Corporation shall not be required to cause appropriate officers of the
Corporation or its Affiliates to participate in a “road show” or similar marketing effort
being conducted by such managing underwriter with respect to such Underwritten Offering
unless such Holders reasonably anticipate gross proceeds from such Underwritten Offering of
at least $30,000,000, and provided, further, that the Corporation shall not be required to
cause appropriate officers of the Corporation or its Affiliates to participate in a “road
show” with respect to Underwritten Offerings under Resale Registration Statements more than
once in any six-month period.

     (ii) Piggyback Registration. If the Registration Statement (or prospectus
supplement with respect to an Underwritten Offering pursuant to an effective shelf
Registration Statement) under which the Corporation gives notice under Section 2(b) is for
an Underwritten Offering, the Corporation shall so advise the Holders of shares of Common
Stock that constitute Registrable Securities. Notwithstanding any other provision of this
Agreement, if the managing underwriter(s) determine(s) in good faith that marketing factors
require a limitation on the number of securities to be included, then the managing
underwriter(s) may exclude securities (including such shares of Common Stock) from the
Piggyback Registration Statement and Underwritten Offering, and any securities included in
such Piggyback Registration Statement and Underwritten Offering shall be allocated first, to
the Corporation, and second, to each of the Holders requesting inclusion of their eligible
shares of Common Stock in such Piggyback Registration Statement and other holders of
securities of the Corporation (on a pro rata basis based on the total number of shares of
Common Stock then held by each such Holder of Common Stock who is requesting inclusion.

     (iii) General Procedures. Any Holder’s right to include its shares of Common
Stock that constitute Registrable Securities in a Resale Registration Statement pursuant to
Section 2(c)(i) or a Piggyback Registration Statement pursuant to Section 2(c)(ii) shall be
conditioned upon such Holder’s participation in such underwriting and the inclusion of such
Holder’s eligible shares of Common Stock in the underwriting to the extent provided herein.
All Holders proposing to distribute their eligible shares of Common

8

 

Stock through such underwriting shall enter into an underwriting agreement in customary
form with the managing underwriter(s) selected for such underwriting and complete and
execute any questionnaires, powers of attorney, indemnities, securities escrow agreements
and other documents reasonably required under the terms of such underwriting, and furnish to
the Corporation such information as the Corporation may reasonably request in writing for
inclusion in the Piggyback Registration Statement or Resale Registration Statement, as the
case may be; provided, however, that no Holder shall be required to make any representations
or warranties to or agreements with the Corporation or the underwriters other than
representations, warranties or agreements regarding such Holder, its holdings and such
Holder’s intended method of distribution and any other representation required by law.

     (iv) Market Stand-Off. Regardless of whether a Holder elects to include shares
of Common Stock that constitute Registrable Securities in an Underwritten Offering, each
Holder of Registrable Securities hereby agrees that it shall not, to the extent requested by
the Corporation or an underwriter of securities of the Corporation, directly or indirectly
sell, offer to sell (including without limitation any short sale or hedging or similar
transaction with the same economic effect as a sale), grant any option or otherwise transfer
or dispose of any Registrable Securities or other securities of the Corporation or any
securities convertible into or exchangeable or exercisable for Common Stock of the
Corporation then owned by such Holder (other than to donees, partners or members of the
Holder who agree to be similarly bound) for a period not to exceed 90 days following the
effective date of a registration statement for an Underwritten Offering or the date of a
prospectus supplement filed with the Commission with respect to the pricing of an
Underwritten Offering, other than the sale or distribution of shares of Common Stock that
constitute Registrable Securities in such Underwritten Offering; provided, however, that:

     (A) such period shall in no event be greater than that which applies to
executive officers and directors of the Corporation;

     (B) the Holders shall be allowed any concession or proportionate release
allowed to any of the Corporation’s officers or directors that entered into similar
agreements (with such proportion being determined by dividing the number of shares
of Common Stock being released with respect to such officer or director by the total
number of issued and outstanding shares of Common Stock held by such officer or
director); and

     (C) this Section 2(c)(iv) shall not apply to Underwritten Offerings solely for
the account of another selling stockholder (other than a Holder) or in the event the
Corporation is not selling at least $20,000,000 worth of Common Stock.

In order to enforce the foregoing covenant, the Corporation shall have the right to impose stop
transfer instructions with respect to the Registrable Securities and such other securities of each
Holder (and the securities of every other Person subject to the foregoing restriction) until the
end of such period.

9

 

     (v) Withdrawal. If any Holder disapproves of the terms of an Underwritten
Offering, such Holder may elect to withdraw therefrom by written notice to the Corporation
and the managing underwriter delivered (i) prior to the commencement of any marketing
efforts for the Underwritten Offering or (ii) at any time up to and including the time of
pricing of the Underwritten Offering if the price to the public at which the Registrable
Securities are proposed to be sold is less than 95% of the average of the closing sale price
per share for the Common Stock (or if the Common Stock is not listed or traded on a national
securities exchange, the average of the last reported bid and ask prices per share) for each
of the 10 consecutive trading days ending on the trading day immediately preceding the
fourth trading day prior to commencement of the marketing efforts for the Underwritten
Offering.

The Holder may agree to waive this right to withdraw with the Corporation, the underwriters
or any custodial agent in any custody agreement and/or power of attorney executed by such
Holder in connection with the underwriting. Any Registrable Securities excluded or
withdrawn from such underwriting shall be excluded and withdrawn from such Registration
Statement. No such withdrawal shall affect the Corporation’s obligation to pay all
Registration Expenses, as described in Section 2(d) below.

     (vi) Selection of Underwriter. In connection with any Underwritten Offering
under Section 2(c)(i) or 2(c)(ii), the Board of Directors of the Corporation shall have the
sole right to select the managing underwriter(s) for each Underwritten Offering, which shall
all be nationally recognized firms. Notwithstanding the above, if White Deer Energy, L.P.
or any of its affiliates is the Holder and is selling shares of Common Stock in such
Underwritten Offering for its own account and such shares constitute a majority of the
shares sold in such Underwritten Offering, and so long as White Deer Energy, L.P. or any of
its affiliates has a board designee on the Board of Directors pursuant to Section 4.1 of the
Purchase Agreement, then the Investor Directors (as defined in the Purchase Agreement) shall
have the right to select the managing underwriter(s) in their sole discretion.

     (e) Expenses. The Corporation shall pay all Registration Expenses in connection with
the registration of the Registrable Securities pursuant to this Agreement. Each Holder
participating in a registration pursuant to this Section 2 shall pay all transfer taxes payable by
such Holder and bear such Holder’s proportionate share (based on the total number of Registrable
Securities sold in such registration) of all discounts and commissions payable to underwriters or
brokers in connection with a registration of Registrable Securities pursuant to this Agreement.

3. RULE 144 REPORTING.

     With a view to making available the benefits of certain rules and regulations of the
Commission that may at any time permit the sale of the Registrable Securities to the public without
registration, the Corporation agrees to:

     (a) use commercially reasonable efforts to make and keep available adequate current public
information, as those terms are understood and defined in Rule 144, at all times after the Closing
Date;

     (b) use commercially reasonable efforts to file with the Commission in a timely manner all
reports and other documents required to be filed by the Corporation under the Securities Act and
the Exchange Act (at any time that it is subject to such reporting requirements); and

     (c) so long as a Holder owns any Registrable Securities, to furnish to the Holder promptly
upon request (i) a written statement by the Corporation as to its compliance with the reporting
requirements of Rule 144 (at any time 90 days after the Closing Date) and of the Securities Act and
the Exchange Act, and (ii) such other reports and documents of the Corporation as a Holder may
reasonably request and that are not otherwise publicly filed with the Commission or available on
the Corporation’s website in availing itself of any rule or regulation of the Commission allowing a
Holder to sell any such Registrable Securities without registration.

4. REGISTRATION PROCEDURES.

     (a) In connection with the obligations of the Corporation with respect to any registration
pursuant to this Agreement, (x) the Corporation shall use its commercially reasonable efforts to
effect or cause to be effected the registration of the Registrable Securities under the Securities
Act to permit the sale of such Registrable Securities by the Holder or Holders in accordance with
the Holder’s or Holders’ intended method or methods of distribution, and (y) the Corporation shall:

     (i) Prepare and file with the Commission a Registration Statement and use its
commercially reasonable efforts to cause such Registration Statement to become effective as
soon as practicable after filing and to remain effective, subject to Section 2(b)(ii) and
Section 5, until there are no Registrable Securities outstanding;

     (ii) subject to Section 4(a)(vii), and Section 5, (1) prepare and file with the
Commission such amendments and post-effective amendments to each such Registration Statement
as may be necessary to keep such Registration Statement effective for the period described
in Section 4(a)(i); (2) cause each Prospectus contained therein to be supplemented by any
required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 or
any similar rule that may be adopted under the Securities Act; and (3) amend or supplement
each such Registration Statement to include the Corporation’s quarterly and annual financial
information and other material developments (until the Corporation is eligible to
incorporate such information by reference into the Registration Statement), during which
time sales of the Registrable

11

 

Securities under the Registration Statement will be suspended until such amendment or
supplement is filed and, in the case of an amendment, is effective;

     (iii) furnish to the Holders, without charge, as many copies of each Prospectus,
including each preliminary Prospectus, if any, and any amendment or supplement thereto and
such other documents as such Holder may reasonably request, in order to facilitate the
public sale or other disposition of the Registrable Securities;

     (iv) use its commercially reasonable efforts to register or qualify, or obtain
exemption from registration or qualification for, all Registrable Securities by the time the
applicable Registration Statement is declared effective by the Commission under all
applicable state securities or blue sky laws of such jurisdictions in the United States as
any Holder of Registrable Securities covered by a Registration Statement shall reasonably
request in writing, keep each such registration or qualification or exemption effective
during the period such Registration Statement is required to be kept effective pursuant to
Section 4(a)(i) and do any and all other acts and things that may be reasonably necessary or
advisable to enable such Holder to consummate the disposition in each such jurisdiction of
such Registrable Securities owned by such Holder; provided, however, that the Corporation
shall not be required to (1) qualify generally to do business in any jurisdiction or to
register as a broker or dealer in such jurisdiction where it would not otherwise be required
to qualify but for this Section 4(a)(iv) and except as may be required by the Securities
Act, (2) subject itself to taxation in any such jurisdiction, or (3) submit to the general
service of process in any such jurisdiction;

     (v) notify each Holder promptly and, if requested by any Holder, confirm such advice in
writing (1) when a Registration Statement has become effective and when any post-effective
amendments and supplements thereto become effective, (2) of the issuance by the Commission
or any state securities authority of any stop order suspending the effectiveness of a
Registration Statement or the initiation of any proceedings for that purpose, (3) of any
request by the Commission or any other federal, state or foreign governmental authority for
amendments or supplements to a Registration Statement or related Prospectus or for
additional information, and (4) of the happening of any event during the period a
Registration Statement is effective as a result of which such Registration Statement or the
related Prospectus or any document incorporated by reference therein contains any untrue
statement of a material fact or omits to state any material fact required to be stated
therein or necessary to make the statements therein not misleading (which notice may be in
the form of a Suspension Notice under Section 5(b));

     (vi) except as provided in Section 5, use commercially reasonable efforts to obtain the
withdrawal of any order enjoining or suspending the use or effectiveness of a Registration
Statement or suspension of the qualification (or exemption from qualification) of any of the
Registrable Securities for sale in any jurisdiction, as promptly as reasonably practicable;

     (vii) except as provided in Section 5, upon the occurrence of any event contemplated by
Section 4(a)(v)(4), use its commercially reasonable efforts to promptly prepare a supplement
or post-effective amendment to a Registration Statement or the

12

 

related Prospectus or any document incorporated therein by reference or file any other
required document so that, as thereafter delivered to the purchasers of the Registrable
Securities, such Prospectus will not contain any untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made, not
misleading;

     (viii) in the case of an Underwritten Offering, use its commercially reasonable efforts
to furnish to the underwriters a signed counterpart, addressed to the underwriters, of: (1)
an opinion of counsel for the Corporation, dated the date of each closing under the
underwriting agreement, in customary form and reasonably satisfactory to the underwriters,
and (2) a “comfort” letter, dated the date of the final prospectus supplement for such
offering or, if there is no prospectus supplement, the effective date of such Registration
Statement and the date of each closing under the underwriting agreement, signed by the
independent registered public accounting firm that has certified the Corporation’s financial
statements included in such Registration Statement, covering substantially the same matters
with respect to such Registration Statement (and the Prospectus included therein) and with
respect to events subsequent to the date of such financial statements, as are customarily
covered in accountants’ letters delivered to underwriters in underwritten public offerings
of securities and such other financial matters as the underwriters may reasonably request;

     (ix) in the case of an Underwritten Offering, enter into an underwriting agreement in
customary form with the underwriters and take all other action required thereunder in order
to expedite or facilitate the distribution of the Registrable Securities included in such
Registration Statement and make representations and warranties to the underwriters in such
form and scope as are customarily made by issuers to underwriters in such underwritten
offerings and confirm the same to the extent customary if and when requested;

     (x) make available for inspection by representatives of the Holders and the
representative of any underwriters participating in any disposition pursuant to a
Registration Statement and any special counsel or accountants retained by such Holders or
underwriters, all financial and other records, pertinent corporate documents and properties
of the Corporation and cause the respective officers, directors and employees of the
Corporation to supply all information reasonably requested by any such representatives, the
representative of the underwriters, counsel thereto or accountants in connection with a
Registration Statement; provided, however, that such records, documents or information that
the Corporation determines, in good faith, to be confidential and notifies such
representatives, representative of the underwriters, counsel thereto or accountants are
confidential shall not be disclosed by the representatives, representative of the
underwriters, counsel thereto or accountants unless (1) the disclosure of such records,
documents or information is necessary to avoid or correct a misstatement or omission in a
Registration Statement or Prospectus, (2) the release of such records, documents or
information is ordered pursuant to a subpoena or other order from a court of competent
jurisdiction, or (3) such records, documents or information have been generally made
available to the public;

13

 

     (xi) if the Corporation is then publicly listed or traded, use its commercially
reasonable efforts to list or include shares of Common Stock that constitute Registrable
Securities on the primary national securities exchange or inter-dealer quotation system on
which similar securities issued by the Corporation are then listed or traded, or if the
Corporation is not then publicly listed but the Corporation meets the criteria for listing
on such exchange or market, use its commercially reasonable efforts to list or include the
Common Stock on the New York Stock Exchange, the Nasdaq Global Market or the Nasdaq Global
Select Market (as soon as practicable), as selected by the Corporation, including seeking to
cure in its listing or inclusion application any deficiencies cited by the exchange or
market, and thereafter maintain the listing on such exchange;

     (xii) prepare and file all documents and reports required by the Exchange Act and, to
the extent the Corporation’s obligation to file such reports pursuant to Section 15(d) of
the Exchange Act expires prior to the expiration of the effectiveness period of the
Registration Statement as required by Section 4(a)(i), the Corporation shall voluntarily
file such reports pursuant to Section 15(d) of the Exchange Act through the effectiveness
period required by Section 4(a)(i);

     (xiii) provide a CUSIP number for all Registrable Securities, not later than the
effective date of the Registration Statement;

     (xiv) (1) otherwise use its commercially reasonable efforts to comply with all
applicable rules and regulations of the Commission, and (2) make generally available to its
securityholders, as soon as reasonably practicable, earnings statements covering at least 12
months that satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 (or
any similar rule promulgated under the Securities Act ) thereunder;

     (xv) provide and cause to be maintained a registrar and transfer agent for all
Registrable Securities; and

     (xvi) in connection with any sale or transfer of the Registrable Securities (whether or
not pursuant to a Registration Statement) that will result in the securities being delivered
no longer being Registrable Securities, cooperate with the Holders and the representative of
the underwriters, if any, to facilitate the timely preparation and delivery of any
certificates representing the Registrable Securities to be sold and to enable such
Registrable Securities to be in such denominations and registered in such names as the
representative of the underwriters, if any, or the Holders may request at least two (2)
Business Days prior to any sale of the Registrable Securities, provided that such Holder
shall have provided the Corporation with any documents that are reasonably requested by the
Corporation.

     (b) The Corporation may require, and it shall be a condition precedent to the obligations of
the Corporation to take any action pursuant to Section 2, with respect to the Registrable
Securities of any selling Holder, that each selling Holder furnish to the Corporation such
information regarding itself, the Registrable Securities held by it and the intended method of
disposition of such securities as shall be required to effect the registration of its Registrable
Securities. In addition, if requested by the Corporation or the representative of the underwriters

14

 

of securities of the Corporation, each Holder shall provide, within ten (10) days of such
request, such information as may be required by the Corporation or such representative in
connection with the completion of any public offering of the Corporation’s securities pursuant to a
Registration Statement filed under the Securities Act. Each Holder further agrees to furnish
promptly to the Corporation in writing all information required from time to time to make the
information previously furnished by such Holder not misleading. No Holder shall have any right to
obtain or seek an injunction restraining or otherwise delaying any such registration as the result
of any controversy that might arise with respect to the interpretation or implementation of this
Agreement.

     (c) Each Holder agrees that, upon receipt of any notice from the Corporation of the happening
of any event of the kind described in Sections 4(a)(v)(3) or 4(a)(v)(4), such Holder will
immediately discontinue disposition of Registrable Securities pursuant to a Registration Statement
until such Holder’s receipt of the copies of the supplemented or amended Prospectus. If so
directed by the Corporation, such Holder will deliver to the Corporation (at the expense of the
Corporation) all copies in its possession, other than permanent file copies then in such Holder’s
possession, of the Prospectus covering such Registrable Securities current at the time of receipt
of such notice.

     (d) The Corporation agrees that, unless it obtains the prior consent of Holders of a majority
of the Registrable Securities that are registered under a Registration Statement at such time or
the consent of the managing underwriter in connection with any Underwritten Offering of shares of
Common Stock that constitute Registrable Securities, it will not make any offer relating to the
Common Stock that would constitute an “issuer free writing prospectus,” as defined in Rule 433, or
that would otherwise constitute a “free writing prospectus,” as defined in Rule 405 (an “Issuer
Free Writing Prospectus”), required to be filed with the Commission. Each Holder represents
and agrees that, unless it obtains the prior consent of the Corporation and any such underwriter,
it will not make any offer relating to the Registrable Securities that would constitute an Issuer
Free Writing Prospectus.

5. BLACK-OUT PERIOD.

     (a) Anything in this Agreement to the contrary notwithstanding, subject to the provisions of
this Section 5, following the effectiveness of a Registration Statement, the Corporation may direct
the Holders in accordance with Section 5(b) to suspend sales of the Registrable Securities pursuant
to a Registration Statement for such times as the Corporation reasonably may determine is necessary
and advisable (but for no more than an aggregate of one-hundred (120) days in any rolling twelve
(12)-month period commencing on the Closing Date (provided that no more than sixty (60) days of
such one hundred twenty (120) days may be as a result of the following events (after excluding the
days between the filing of any post-effective amendment to a registration statement with the
Commission as a result of such events through the day such post-effective amendment is declared
effective)) or for more than sixty (60) days in any rolling 90-day period as a result of such
events (after excluding the days between the filing of any post-effective amendment to a
registration statement with the Commission as a result of such events through the day such
post-effective amendment is declared effective), if any of the following events shall occur: (i) a
majority of the members of the Board of Directors of the Corporation shall have determined in good
faith that (1) the offer or sale of any Registrable

15

 

Securities would materially impede, delay or interfere with any proposed acquisition, merger,
tender offer, business combination, corporate reorganization, consolidation or other significant
transaction involving the Corporation, (2) after the advice of counsel, the sale of Registrable
Securities pursuant to the Registration Statement would require disclosure of material non-public
information not otherwise required to be disclosed under applicable law, and (3) either (x) the
Corporation has a bona fide business purpose for preserving the confidentiality of such
transaction, (y) disclosure would have a material adverse effect on the Corporation or the
Corporation’s ability to consummate such transaction, or (z) the proposed transaction renders the
Corporation unable to comply with Commission requirements; (ii) a majority of the members of the
Board of Directors of the Corporation shall have determined in good faith that (1) the Prospectus
included in the Registration Statement contains a material misstatement or omission as a result of
an event that has occurred subsequent to the date of such Prospectus and is continuing; and (2) the
disclosure of this material non-public information would be detrimental to the Corporation; (iii) a
majority of the members of the Board of Directors of the Corporation shall have determined in good
faith, after the advice of counsel, that it is required by law, rule or regulation to supplement
the Registration Statement or file a post-effective amendment to the Registration Statement in
order to incorporate information into the Registration Statement for the purpose of (1) including
in the Registration Statement any Prospectus required under Section 10(a)(3) of the Securities Act,
(2) reflecting in the Prospectus included in the Registration Statement any facts or events arising
after the effective date of the Registration Statement (or of the most-recent post-effective
amendment) that, individually or in the aggregate, represents a fundamental change in the
information set forth therein, or (3) including in the Prospectus included in the Registration
Statement any material information with respect to the plan of distribution not disclosed in the
Registration Statement or any material change to such information; or (iv) a majority of the
members of the Board of Directors of the Corporation shall have determined to convert the Resale
Registration Statement on Form S-1 to a Resale Registration Statement on Form S-3. In addition,
the Corporation may direct the Holders in accordance with Section 5(b) to suspend sales of the
Registrable Securities pursuant to a Registration Statement from time to time under Section
4(a)(ii) and Section 4(c). Upon the occurrence of any such suspension under clauses (iii) or (iv),
the Corporation shall use its commercially reasonable efforts to cause the Registration Statement
to become effective or to promptly amend or supplement the Registration Statement on a
post-effective basis or to take such action as is necessary to make resumed use of the Registration
Statement compatible with the Corporation’s best interests, as applicable, so as to permit the
Holders to resume sales of the Registrable Securities as soon as reasonably practicable.

     (b) In the case of an event that causes the Corporation to suspend the use of a Registration
Statement (a “Suspension Event”), the Corporation shall give written notice (a
“Suspension Notice”) to the Holders to suspend sales of the Registrable Securities. The
Holders shall not effect any sales of the Registrable Securities pursuant to such Registration
Statement (or such filings) at any time after they have received a Suspension Notice from the
Corporation and prior to receipt of an End of Suspension Notice (as defined below). If so directed
by the Corporation, each Holder will deliver to the Corporation (at the expense of the Corporation)
all copies other than permanent file copies then in such Holder’s possession of the Prospectus
covering the Registrable Securities at the time of receipt of the Suspension Notice. The Holders
may recommence effecting sales of the Registrable Securities pursuant to the Registration Statement
(or such filings) following further notice to such effect (an “End of Suspension

16

 

Notice”) from the Corporation, which End of Suspension Notice shall be given by the
Corporation to the Holders in the manner described above promptly following the conclusion of any
Suspension Event and its effect. The Corporation shall not be required to specify in the written
notice to the Holders the nature of the event giving rise to the suspension period. Holders hereby
agree to hold in confidence any communications in response to a notice of, or the existence of any
fact or any event giving rise to the suspension period.

     (c) Notwithstanding any provision herein to the contrary, if the Corporation shall give a
Suspension Notice pursuant to this Section 5, the Corporation agrees that it shall extend the
period of time during which the applicable Registration Statement shall be maintained effective
pursuant to this Agreement by the number of days during the period from the date of receipt by the
Holders of the Suspension Notice to and including the date of receipt by the Holders of the End of
Suspension Notice and copies of the supplemented and amended Prospectus necessary to resume sales.

6. INDEMNIFICATION AND CONTRIBUTION.

     (a) The Corporation agrees to indemnify and hold harmless (i) each Holder of Registrable
Securities and any underwriter (as determined in the Securities Act) for such Holder, (ii) each
Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section
20(a) of the Exchange Act), any such Person described in clause (i) (any of the Persons referred to
in this clause (ii) being hereinafter referred to as a “Controlling Person”), and (iii) the
respective officers, directors, partners, members, employees, representatives and agents of any
such Person or any Controlling Person (any Person referred to in clause (i), (ii) or (iii) may
hereinafter be referred to as a “Purchaser Indemnitee”), to the fullest extent lawful, from
and against any and all losses, claims, damages, judgments, actions, reasonable out-of-pocket
expenses, and other liabilities (the “Liabilities”), including without limitation and as
incurred, reimbursement of all reasonable out-of-pocket costs of investigating, preparing, pursuing
or defending any claim or action, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, including the reasonable fees and expenses of counsel to any
Purchaser Indemnitee to the extent provided herein, joint or several, directly or indirectly
related to, based upon, arising out of or in connection with any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement or Prospectus (as amended or
supplemented if the Corporation shall have furnished to such Purchaser Indemnitee any amendments or
supplements thereto), or any Issuer Free Writing Prospectus (or any amendment or supplement
thereto), or any preliminary Prospectus or any other document prepared by or with the Corporation
for use in selling the securities, or any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, except insofar as such Liabilities arise
out of or are based upon (i) any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with information relating to any Purchaser
Indemnitee furnished to the Corporation or any underwriter in writing by such Purchaser Indemnitee
expressly for use therein, (ii) any sales by any Holder after the delivery by the Corporation to
such Holder of a Suspension Notice and before the delivery by the Corporation of an End of
Suspension Notice, or (iii) the failure by a Purchaser Indemnitee to deliver a Prospectus, if
delivery is otherwise required. The Corporation shall notify the Holders promptly of the
institution, threat or assertion of any claim, proceeding (including any

17

 

governmental investigation), or litigation of which it shall have become aware in connection
with the matters addressed by this Agreement which involves the Corporation or a Purchaser
Indemnitee. The indemnity provided for herein shall remain in full force and effect regardless of
any investigation made by or on behalf of any Purchaser Indemnitee.

     (b) In connection with any Registration Statement in which a Holder of Registrable Securities
is participating, such Holder agrees, severally and not jointly, to indemnify and hold harmless the
Corporation, each Person who controls the Corporation within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act and the respective officers, directors,
partners, members, employees, representatives and agents of such Person or Controlling Person to
the same extent as the foregoing indemnity from the Corporation to each Purchaser Indemnitee, but
only with reference to (i) untrue statements or omissions or alleged untrue statements or omissions
made in reliance upon and in strict conformity with information relating to such Holder furnished
to the Corporation in writing by such Holder expressly for use in any Registration Statement or
Prospectus, any amendment or supplement thereto, any Issuer Free Writing Prospectus (or any
amendment or supplement thereto) or any preliminary Prospectus, (ii) any sales by such Holder after
the delivery by the Corporation to such Holder of a Suspension Notice and before the delivery by
the Corporation of an End of Suspension Notice, or (iii) the failure by a Purchaser Indemnitee to
deliver a Prospectus, if required. The liability of any Holder pursuant to this subsection shall
in no event exceed the gross proceeds received by such Holder from sales of Registrable Securities
giving rise to such obligations.

     (c) If any Proceeding (including any governmental or regulatory investigation), claim or
demand shall be brought or asserted against any Person in respect of which indemnity may be sought
pursuant to subsection (a) or (b) above, such Person (the “Indemnified Party”) shall
promptly notify the Person against whom such indemnity may be sought (the “Indemnifying
Party”), in writing of the commencement thereof (but the failure to so notify an Indemnifying
Party shall not relieve it from any liability which it may have under this Section 6, except to the
extent the Indemnifying Party is materially prejudiced by the failure to give notice), and the
Indemnifying Party shall be entitled to assume the defense thereof and retain counsel reasonably
satisfactory to the Indemnified Party to represent the Indemnified Party and any others the
Indemnifying Party may reasonably designate in such proceeding and shall pay the reasonable fees
and expenses actually incurred by such counsel related to such proceeding. Notwithstanding the
foregoing, in any such proceeding, any Indemnified Party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified
Party, unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed in
writing to the contrary, (ii) the Indemnifying Party failed within a reasonable time after notice
of commencement of the action to assume the defense and employ counsel reasonably satisfactory to
the Indemnified Party, (iii) the Indemnifying Party and its counsel do not actively and vigorously
pursue the defense of such action or (iv) the named parties to any such action (including any
impleaded parties), include both such Indemnified Party and the Indemnifying Party, or any
Affiliate of the Indemnifying Party, and such Indemnified Party shall have been reasonably advised
by counsel that, either (x) there may be one or more legal defenses available to it which are
different from or additional to those available to the Indemnifying Party or such Affiliate of the
Indemnifying Party or (y) a conflict may exist between such Indemnified Party and the Indemnifying
Party or such Affiliate of the Indemnifying Party (in which case the Indemnifying Party shall not
have the right to assume nor direct the defense of such action on

18

 

behalf of such Indemnified Party, it being understood, however, that the Indemnifying Party
shall not, in connection with any one such action or separate but substantially similar or related
actions in the same jurisdiction arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys (in addition to any
local counsel), for all such Indemnified Parties, which firm shall be designated in writing by
those Indemnified Parties who sold a majority of the Registrable Securities sold by all such
Indemnified Parties and any such separate firm for the Corporation, the directors, the officers and
such control Persons of the Corporation as shall be designated in writing by the Corporation). The
Indemnifying Party shall not be liable for any settlement of any proceeding effected without its
written consent, which consent shall not be unreasonably withheld, but if settled with such consent
or if there is a final judgment for the plaintiff, the Indemnifying Party agrees to indemnify any
Indemnified Party from and against any loss or liability by reason of such settlement or judgment.
No Indemnifying Party shall, without the prior written consent of the Indemnified Party, which
consent shall not be unreasonably withheld, effect any settlement of any pending or threatened
proceeding in respect of which any Indemnified Party is or could have been a party and indemnity
could have been sought hereunder by such Indemnified Party, unless such settlement includes an
unconditional release of such Indemnified Party from all liability on claims that are the subject
matter of such proceeding.

     (d) If the indemnification provided for in subsections (a) and (b) of this Section 6 is for
any reason held to be unavailable to an Indemnified Party in respect of any Liabilities referred to
therein (other than by reason of the exceptions provided therein) or is insufficient to hold
harmless a party indemnified thereunder, then each Indemnifying Party under such subsections, in
lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or
payable by such Indemnified Party as a result of such Liabilities (i) in such proportion as is
appropriate to reflect the relative benefits of the Indemnified Party on the one hand and the
Indemnifying Party(ies) on the other in connection with the statements or omissions that resulted
in such Liabilities, or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Indemnifying Party(ies) and the
Indemnified Party, as well as any other relevant equitable considerations. The relative fault of
the Corporation on the one hand and any Purchaser Indemnitees on the other shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to information supplied by the
Corporation or by such Purchaser Indemnitees and the parties’ relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

     (e) The parties agree that it would not be just and equitable if contribution pursuant to this
Section 6 were determined by pro rata allocation (even if such Indemnified Parties were treated as
one entity for such purpose), or by any other method of allocation that does not take account of
the equitable considerations referred to in Section 6(d) above. The amount paid or payable by an
Indemnified Party as a result of any Liabilities referred to in Section 6(d) shall be deemed to
include, subject to the limitations set forth above, any reasonable out-of-pocket legal or other
expenses actually incurred by such Indemnified Party in connection with investigating or defending
any such action or claim. Notwithstanding the provisions of this Section 6, in no event shall a
Purchaser Indemnitee be required to contribute any amount in excess of the amount

19

 

by which proceeds received by such Purchaser Indemnitee from sales of Registrable Securities
exceeds the amount of any damages that such Purchaser Indemnitee has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged omission. For purposes
of this Section 6, each Person, if any, who controls (within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act) a Holder of Registrable Securities shall have
the same rights to contribution as such Holder, as the case may be, and each Person, if any, who
controls (within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange
Act) the Corporation, and each officer, director, partner, member, employee, representative and
agent of the Corporation shall have the same rights to contribution as the Corporation. Any party
entitled to contribution will, promptly after receipt of notice of commencement of any Proceeding
against such party in respect of which a claim for contribution may be made against another party
or parties, notify each party or parties from whom contribution may be sought, but the omission to
so notify such party or parties shall not relieve the party or parties from whom contribution may
be sought from any obligation it or they may have under this Section 6 or otherwise, except to the
extent that any party is materially prejudiced by the failure to give notice. No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act), shall be
entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

     (f) The indemnity and contribution agreements contained in this Section 6 will be in addition
to any liability which the Indemnifying Parties may otherwise have to the Indemnified Parties
referred to above. The Purchaser Indemnitees’ obligations to contribute pursuant to this Section 6
are several in proportion to the respective number of securities sold by each of the Purchaser
Indemnitees hereunder and not joint.

7. LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS.

     From and after the date of this Agreement, the Corporation shall not, without the prior
written consent of Holders beneficially owning not less than two-thirds (2/3) of the then
outstanding Registrable Securities, enter into any agreement with any holder or prospective holder
of any securities of the Corporation that would grant such holder registration rights senior to
those granted to the Holders hereunder with respect to Section 2(c)(ii).

8. MISCELLANEOUS.

     (a) Remedies. In the event of a breach by the Corporation of any of its obligations
under this Agreement, each Holder, in addition to being entitled to exercise all rights provided
herein, or granted by law, including recovery of damages, will be entitled to specific performance
of its rights under this Agreement. Subject to Section 6, the Corporation agrees that monetary
damages would not be adequate compensation for any loss incurred by reason of a breach by it of any
of the provisions of this Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that a remedy at law
would be adequate.

     (b) Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents
to or departures from the provisions hereof may not be given, without the written

20

 

consent of the Corporation and Holders beneficially owning not less than two-thirds (2/3) of
the then outstanding Registrable Securities. No amendment shall be deemed effective unless it
applies uniformly to all Holders. Notwithstanding the foregoing, a waiver or consent to or
departure from the provisions hereof with respect to a matter that relates exclusively to the
rights of a Holder whose securities are being sold pursuant to a Registration Statement and that
does not directly or indirectly affect, impair, limit or compromise the rights of other Holders may
be given by such Holder; provided that the provisions of this sentence may not be amended, modified
or supplemented except in accordance with the provisions of the immediately preceding sentence.

     (c) Notices. All notices and other communications, provided for or permitted
hereunder shall be made in writing and delivered by facsimile (with receipt confirmed), overnight
courier or registered or certified mail, return receipt requested, or e-mail (if an e-mail address
is provided by a Holder):

     (i) if to a Stockholder, at the address given by the Stockholder on its
signature page hereto (or, if more recent, at an address contained in a
written notice from the Holder); and

     (ii) if to the Corporation at the offices of the Corporation at:

PostRock Energy Corporation

210 Park Avenue, Suite 2750

Oklahoma City, OK 73102

Attention: Chief Executive Officer

Telephone: (405) 702-7487

Facsimile: (405) 702-7756

     (d) Successors and Assigns. This Agreement shall inure to the benefit of and be
binding upon the successors and permitted assigns of each of the parties hereto. The rights to
cause the Corporation to register Registrable Securities pursuant to this Agreement may be assigned
by a Holder to a transferee or assignee of Registrable Securities that (a) is a subsidiary, parent,
general partner, limited partner, member, or shareholder of a Holder, (b) is a Holder’s family
member or trust for the benefit of an individual Holder, (c) together with its Affiliates, acquires
in excess of 4,800 Series A Shares or 15,238,095 shares of Common Stock (as adjusted for splits and
combinations), or (d) is an Affiliate of such Holder, provided, however, that such transfer shall
not be effective for purposes of this Agreement until (i) the transferor shall furnish to the
Corporation written notice of the name and address of such transferee or assignee and the
securities with respect to which such registration rights are being assigned and (ii) such
transferee shall agree to be subject to all restrictions set forth in this Agreement. Each Holder
agrees that any transferee of any Registrable Securities shall be bound by Section 4(b) and Section
7, whether or not such transferee expressly agrees to be bound.

     (e) Merger, Amalgamation, Consolidation, Etc. of the Corporation. If the Corporation
is a party to any merger, amalgamation, consolidation, recapitalization, reorganization or
otherwise pursuant to which the Registrable Securities are converted into or exchanged for
securities or the right to receive securities of any other person (“Conversion

21

 

Securities”), the issuer of such Conversion Securities shall assume (in a writing
delivered to all Holders) all obligations of the Corporation hereunder. The Corporation will not
effect any merger, amalgamation, consolidation, recapitalization, reorganization or otherwise
described in the immediately preceding sentence unless the issuer of the Conversion Securities
complies with this Section 8(e).

     (f) Aggregation of Registrable Securities. All Registrable Securities held or
acquired by Persons who are Affiliates of one another shall be aggregated together for the purpose
of determining the availability of any rights under this Agreement.

     (g) Counterparts. This Agreement may be executed in any number of counterparts and by
the parties hereto in separate counterparts, each of which when so executed shall be deemed to be
an original and all of which taken together shall constitute one and the same agreement.

     (h) Headings. The headings in this Agreement are for convenience of reference only
and shall not limit or otherwise affect the meaning hereof.

     (i) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF DELAWARE, AS APPLIED TO CONTRACTS MADE AND PERFORMED WITHIN THE STATE
OF DELAWARE, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

     (j) Severability. If any term, provision, covenant or restriction of this Agreement
is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in
full force and effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their commercially reasonable efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such term, provision,
covenant or restriction. It is hereby stipulated and declared to be the intention of the parties
hereto that they would have executed the remaining terms, provisions, covenants and restrictions
without including any of such that may be hereafter declared invalid, illegal, void or
unenforceable.

     (k) Entire Agreement. This Agreement is intended by the parties hereto as a final
expression of their agreement, and is intended to be a complete and exclusive statement of the
agreement and understanding of the parties hereto, in respect of the subject matter contained
herein.

     (l) Registrable Securities Held by the Corporation. Whenever the consent or approval
of Holders of a specified percentage of Registrable Securities is required hereunder, Registrable
Securities held by the Corporation shall not be counted in determining whether such consent or
approval was given by the Holders of such required percentage.

     (m) Adjustment for Splits, etc. Wherever in this Agreement there is a reference to a
specific number of securities with respect to any Registrable Securities, then upon the occurrence
of any subdivision, combination, or security dividend of such securities, the specific number of
securities with respect to any Registrable Securities so referenced in this Agreement shall

22

 

automatically be proportionally adjusted to reflect the effect on the outstanding securities
of such class or series by such subdivision, combination, or security dividend.

     (n) Survival. The indemnification and contribution obligations under Section 6 of
this Agreement shall survive the termination of the Corporation’s obligations under Section 2 of
this Agreement.

     (o) Attorneys’ Fees. In any action or proceeding brought to enforce any provision of
this Agreement, or where any provision hereof is validly asserted as a defense, the prevailing
party, as determined by the court or arbitrator(s), as the case may be, shall be entitled to
recover its reasonable attorneys’ fees in addition to any other available remedy.
