2. REGISTRATION RIGHTS.




     2.1 Demand Registration.



          2.1.1 Request for Registration. At any time and from time to time, the holders of a
majority-in-interest of the Registrable Securities held by the Pegasus Parties (determined on a
fully diluted basis, including assuming the issuance of all Registrable Securities underlying the
Guarantor Warrant, the “Majority-in-Interest”), may make a written demand for registration under
the Securities Act of all or part of their Registrable Securities (a “Demand Registration”). Any
demand for a Demand Registration shall specify the number of shares of Registrable Securities
proposed to be sold and the intended method(s) of distribution thereof. The Company shall promptly
notify all Pegasus Parties holding Registrable Securities of such demand, and each Pegasus Party
who wishes to include all or a portion of such Pegasus Party’s Registrable Securities in the Demand
Registration (each such Pegasus Party including Registrable Securities in such registration, a
“Demanding Holder”) shall so notify the Company within fifteen (15) days after the receipt by the
Pegasus Party of the notice from the Company. Upon any such request, the Demanding Holders shall be
entitled to have their Registrable Securities included in the Demand Registration, subject to
Section 2.1.4 and the provisos set forth in Section 3.1.1. The Company shall not be obligated to
effect more than an aggregate of three (3) Demand Registrations under this Section 2.1.1 in respect
of Registrable Securities.




          2.1.2 Effective Registration. A registration will not count as a Demand Registration until the
Registration Statement filed with the Commission with respect to such Demand Registration
registering all of the Registrable Securities specified in the notice received pursuant to Section
2.1.1, determined on the basis described in Section 2.1.1, has been declared effective and the
Company has complied with all of its obligations under this Agreement with respect thereto;
provided, however, that if, after such Registration Statement has been declared effective, the
offering of Registrable Securities pursuant to a Demand Registration is interfered with by any stop
order or injunction of the Commission or any other governmental agency or court, the Registration
Statement with respect to such Demand Registration will be deemed not to have been declared
effective, unless and until, (i) such stop order or injunction is removed, rescinded or otherwise
terminated, and (ii) a Majority-in-Interest of the Demanding Holders thereafter elect to continue
the offering; provided, further, that the Company shall not be obligated to file a second
Registration Statement until a Registration Statement that has been filed is counted as a Demand
Registration or is terminated.




          2.1.3 Reduction of Offering. If the Company chooses to engage in an underwritten public
offering of a Demand Registration and if the managing underwriter or underwriters for a Demand
Registration that is to be an underwritten offering advises the Company and the Demanding Holders
in writing that the dollar amount or number of Registrable Securities which the Demanding Holders
desire to sell, taken together with all other shares of Common Stock or other securities which the
Company desires to sell and the shares of Common Stock or other securities, if any, as to which
registration has been requested pursuant to written contractual piggy-back registration rights held
by other stockholders of the Company who desire to sell, exceeds the maximum dollar amount or
maximum number of securities that can be sold in such offering without adversely affecting the
proposed offering price, the timing, the distribution method, or the probability of success of such
offering (such maximum dollar amount or maximum number of securities, as applicable, the “Maximum
Number of Securities”), then the Company shall include in such registration: (i) first, the
Registrable Securities as to which Demand Registration has been requested by the Demanding Holders
and the Registrable Securities, if any, as to which a Piggy- Back Registration has been requested
pursuant to Section 2.2.1 (pro rata in accordance with the number of securities that each




2









 




such Person has requested be included in such registration, regardless of the number of securities
held by each such Person (such proportion is referred to herein as “Pro Rata”)) that can be sold
without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum
Number of Securities has not been reached under the foregoing clause (i), the shares of Common
Stock or other securities that the Company desires to sell that can be sold without exceeding the
Maximum Number of Securities; (iii) third, to the extent that the Maximum Number of Securities has
not been reached under the foregoing clauses (i) and (ii), the shares of Common Stock or other
securities for the account of other Persons that the Company is obligated to register pursuant to
written contractual arrangements with such Persons and that can be sold without exceeding the
Maximum Number of Securities.




          2.1.4 Withdrawal. If a Majority-in-Interest of the Demanding Holders disapprove of the terms
of any underwriting or are not entitled to include all of their Registrable Securities in any
offering, such Majority-in-Interest of the Demanding Holders may elect to withdraw from such
offering by giving written notice to the Company and the Underwriter or Underwriters of their
request to withdraw prior to the effectiveness of the Registration Statement filed with the
Commission with respect to such Demand Registration. If the Majority-in-Interest of the Demanding
Holders withdraws from a proposed offering relating to a Demand Registration, then such
registration shall not count as a Demand Registration provided for in Section 2.1.1.



2.2 Piggy-Back Registration.




          2.2.1 Piggy-Back Rights. Except with respect to the registration statements filed or to be
filed under Rule 415 pursuant to that certain Securities Purchase Agreement, dated as of March 9,
2007, between the Company and the investors party thereto, if at any time the Company proposes to
file a Registration Statement under the Securities Act with respect to an offering of equity
securities, or securities or other obligations exercisable or exchangeable for, or convertible
into, equity securities, by the Company for its own account or for stockholders of the Company for
their account (or by the Company and by stockholders of the Company including, without limitation,
pursuant to Section 2.1 or 2.3), other than a Registration Statement (i) filed in connection with
any employee stock option or other benefit plan, (ii) for an exchange offer or offering of
securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is
convertible into equity securities of the Company or (iv) for a dividend reinvestment plan, then
the Company shall (x) give written notice of such proposed filing to the holders of Registrable
Securities as soon as practicable but in no event less than ten (10) days before the anticipated
filing date, which notice shall describe the amount and type of securities to be included in such
offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter
or Underwriters, if any, of the offering, and (y) offer to the holders of Registrable Securities in
such notice the opportunity to register the sale of such number of Registrable Securities as such
holders may request in writing within ten (10) days following receipt of such notice (a “Piggy-Back
Registration”). The Company shall cause such Registrable Securities to be included in such
registration and shall use its reasonable best efforts to cause the managing Underwriter or
Underwriters of a proposed underwritten offering to permit the Registrable Securities requested to
be included in a Piggy-Back Registration on the same terms and conditions as any similar securities
of the Company and to permit the sale or other disposition of such Registrable Securities in
accordance with the intended method(s) of distribution thereof. All holders of Registrable
Securities proposing to distribute their securities through a Piggy-Back Registration that involves
an Underwriter or Underwriters shall enter into an underwriting agreement in customary form with
the Underwriter or Underwriters selected for such Piggy-Back Registration.




          2.2.2 Reduction of Offering. If the managing Underwriter or Underwriters for a Piggy-Back
Registration that is to be an underwritten offering advises the Company and the holders of
Registrable Securities in writing that the dollar amount or number of securities which the Company
desires to sell, taken together with shares of Common Stock or other securities, if any, as to
which registration has been demanded pursuant to written contractual arrangements with Persons
other than the holders of Registrable Securities hereunder, the Registrable Securities as to which
registration has been requested under this Section 2.2, and the shares of Common Stock or other
securities, if any, as to which registration has been requested pursuant to the written contractual
piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of
Securities, then the Company shall include in any such registration:




          i. If the Registration is a Demand Registration or a Form S-3 Registration, the provisions of
Section 2.1.3 shall apply and references to Demand Registration in Section 2.1.3 shall be deemed to
refer to a Form S-3 Registration as required;




          ii. If the registration is undertaken for the Company’s account: (A) first, the shares of
Common Stock or other securities that the Company desires to sell that can be sold without
exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of
Securities has not been reached under the foregoing clause (A), the shares of Common Stock or other
securities, if any, requested to be registered pursuant to Section 2.2.2(ii) of that certain
Amended and Restated Registration Rights Agreement dated April 22, 2008, by and among the Company
and the investors signatory thereto, that can be sold without exceeding the Maximum Number of
Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached
under the foregoing clauses (A) and (B), the shares of Common Stock or other securities, if any,
that are Registrable Securities, as to which registration has been requested pursuant to the
applicable written contractual piggy-back registration rights of such security holders, Pro Rata,
that can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent
that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and
(C), the shares of Common Stock or other securities for the account of other Persons that the




3









 




Company is obligated to register pursuant to written contractual piggy-back registration rights
with such Persons and that can be sold without exceeding the Maximum Number of Securities; and




          iii. If the registration is a “demand” registration undertaken at the demand of Persons other
than the holders of Registrable Securities pursuant to written contractual arrangements with such
Persons, (A) first, the shares of Common Stock or other securities for the account of the demanding
Persons that can be sold without exceeding the Maximum Number of Securities; (B) second, to the
extent that the Maximum Number of Securities has not been reached under the foregoing clause (A),
the shares of Common Stock or other securities comprised of Registrable Securities, Pro Rata, as to
which registration has been requested pursuant to the terms hereof, that can be sold without
exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of
Securities has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock
or other securities that the Company desires to sell that can be sold without exceeding the Maximum
Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not
been reached under the foregoing clauses (A), (B) and (C), the shares of Common Stock or other
securities for the account of other Persons that the Company is obligated to register pursuant to
written contractual arrangements with such Persons, that can be sold without exceeding the Maximum
Number of Securities.




          2.2.3 Withdrawal. Any holder of Registrable Securities may elect to withdraw such holder’s
request for inclusion of Registrable Securities in any Piggy-Back Registration by giving written
notice to the Company of such request to withdraw prior to the effectiveness of the Registration
Statement. The Company (whether on its own determination or as the result of a withdrawal by
Persons making a demand pursuant to written contractual obligations) may withdraw a registration
statement at any time prior to the effectiveness of the Registration Statement. Notwithstanding any
such withdrawal, the Company shall pay all expenses incurred by the holders of Registrable
Securities in connection with such Piggy-Back Registration as provided in Section 3.3.




     2.3 Registrations on Form S-3. The holders of Registrable Securities that are Pegasus Parties
may at any time and from time to time, request in writing that the Company register (a “Form S-3
Registration”) the resale of any or all of such Registrable Securities on Form S-3 or any similar
short-form registration which may be available at such time (“Form S-3”); provided, however, that
the Company shall not be obligated to effect such request through an underwritten offering. Upon
receipt of such written request, the Company will promptly give written notice of the proposed
registration to all other holders of Registrable Securities that are Pegasus Parties, and, as soon
as practicable thereafter, subject to the provisions on Section 2.2, effect the registration of all
or such portion of such holder’s or holders’ Registrable Securities as are specified in such
request, together with all or such portion of the Registrable Securities or other securities of the
Company, if any, of any other holder or holders that are Pegasus Parties joining in such request as
are specified in a written request given within fifteen (15) days after receipt of such written
notice from the Company; provided, however, that the Company shall not be obligated to effect any
such registration pursuant to this Section 2.3 (i) if Form S-3 is not available for such offering
or (ii) if the holders of the Registrable Securities, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to sell Registrable
Securities and such other securities (if any) at any aggregate price to the public of less than
$500,000. Registrations effected pursuant to this Section 2.3 shall not be counted as Demand
Registrations effected pursuant to Section 2.1.


3. REGISTRATION PROCEDURES.




     3.1 Filings; Information. Whenever the Company is required to effect the registration of any
Registrable Securities pursuant to Section 2, the Company shall use its reasonable best efforts to
effect the registration and sale of such Registrable Securities in accordance with the intended
method(s) of distribution thereof as expeditiously as practicable, and in connection with any such
request:



          3.1.1 Filing Registration Statement. The Company shall, as expeditiously as possible and in
any event within sixty (60) days after receipt of a request for a Demand Registration pursuant to
Section 2.1, prepare and file with the Commission a Registration Statement on any form for which
the Company then qualifies or which counsel for the Company shall deem appropriate and which form
shall be available for the sale of all Registrable Securities to be registered thereunder in
accordance with the intended method(s) of distribution thereof, and shall use its reasonable best
efforts to cause such Registration Statement to become and remain effective for the period required
by Section 3.1.3; provided, however, that the Company shall have the right to defer any Demand
Registration for up to thirty (30) days, and any Piggy-Back Registration for such period as may be
applicable to deferment of any demand registration to which such Piggy-Back Registration relates,
in each case if the Company shall furnish to the holders a certificate signed by the Chief
Executive Officer or Chairman of the Board of the Company stating that, in the good faith judgment
of the Board of Directors of the Company, it would be materially detrimental to the Company and its
stockholders for such Registration Statement to be effected at such time; provided further,
however, that the Company shall not have the right to exercise the right set forth in the
immediately preceding proviso more than once in any 365-day period in respect of a Demand
Registration hereunder.




          3.1.2 Copies. The Company shall, prior to filing a Registration Statement or prospectus, or
any amendment or supplement thereto, furnish without charge to the holders of Registrable
Securities included in such registration, and such holders’ legal counsel, copies of such
Registration Statement as proposed to be filed, each amendment and supplement to




4









 




such Registration Statement (in each case including all exhibits thereto and documents incorporated
by reference therein), the prospectus included in such Registration Statement (including each
preliminary prospectus), and such other documents as the holders of Registrable Securities included
in such registration or legal counsel for any such holders may request in order to facilitate the
disposition of the Registrable Securities owned by such holders.




          3.1.3 Amendments and Supplements. The Company shall prepare and file with the Commission such
amendments, including post-effective amendments, and supplements to such Registration Statement and
the prospectus used in connection therewith as may be necessary to keep such Registration Statement
effective and in compliance with the provisions of the Securities Act until all Registrable
Securities and other securities covered by such Registration Statement have been disposed of in
accordance with the intended method(s) of distribution set forth in such Registration Statement or
such securities have been withdrawn.




          3.1.4 Notification. After the filing of a Registration Statement, the Company shall promptly,
and in no event more than two (2) business days after such filing, notify the holders of
Registrable Securities included in such Registration Statement of such filing, and shall further
notify such holders promptly and confirm such advice in writing in all events within two (2)
business days of the occurrence of any of the following: (i) when such Registration Statement
becomes effective; (ii) when any post- effective amendment to such Registration Statement becomes
effective; (iii) the issuance or threatened issuance by the Commission of any stop order (and the
Company shall take all actions required to prevent the entry of such stop order or to remove it if
entered); and (iv) any request by the Commission for any amendment or supplement to such
Registration Statement or any prospectus relating thereto or for additional information or of the
occurrence of an event requiring the preparation of a supplement or amendment to such prospectus so
that, as thereafter delivered to the purchasers of the securities covered by such Registration
Statement, such prospectus will not contain an untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the statements therein not
misleading, and promptly make available to the holders of Registrable Securities included in such
Registration Statement any such supplement or amendment; except that before filing with the
Commission a Registration Statement or prospectus or any amendment or supplement thereto, including
documents incorporated by reference, the Company shall furnish to the holders of Registrable
Securities included in such Registration Statement and to the legal counsel for any such holders,
copies of all such documents proposed to be filed sufficiently in advance of filing to provide such
holders and legal counsel with a reasonable opportunity to review such documents and comment
thereon, and the Company shall not file any Registration Statement or prospectus or amendment or
supplement thereto, including documents incorporated by reference, to which such holders or their
legal counsel shall object.




          3.1.5 State Securities Laws Compliance. The Company shall use its reasonable best efforts to
(i) register or qualify the Registrable Securities covered by the Registration Statement under such
securities or “blue sky” laws of such jurisdictions in the United States as the holders of
Registrable Securities included in such Registration Statement (in light of their intended plan of
distribution) may request and (ii) take such action necessary to cause such Registrable Securities
covered by the Registration Statement to be registered with or approved by such other governmental
authorities as may be necessary by virtue of the business and operations of the Company and do any
and all other acts and things that may be necessary or advisable to enable the holders of
Registrable Securities included in such Registration Statement to consummate the disposition of
such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be
required to qualify generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this paragraph or subject itself to taxation in any such jurisdiction.




          3.1.6 Agreements for Disposition. The Company shall enter into customary agreements
(including, if applicable, an underwriting agreement in customary form) and take such other actions
as are reasonably required in order to expedite or facilitate the disposition of such Registrable
Securities. The representations, warranties and covenants of the Company in any underwriting
agreement which are made to or for the benefit of any Underwriters, to the extent applicable, shall
also be made to and for the benefit of the holders of Registrable Securities included in such
registration statement. No holder of Registrable Securities included in such registration statement
shall be required to make any representations or warranties in the underwriting agreement except,
if applicable, with respect to such holder’s organization, good standing, authority, title to
Registrable Securities, lack of conflict of such sale with such holder’s material agreements and
organizational documents, and with respect to written information relating to such holder that such
holder has furnished in writing expressly for inclusion in such Registration Statement. Holders of
Registrable Securities shall agree to such covenants and indemnification and contribution
obligations for selling stockholders as are customarily contained in agreements of that type.
Further, such holders shall cooperate fully in the preparation of the Registration Statement and
other documents relating to any offering in which they include securities pursuant to Section 2
hereof. Each holder shall also furnish to the Company such information regarding itself, the
Registrable Securities held by such holder, as applicable, and the intended method of disposition
of such securities as shall be reasonably required to effect the registration of the Registrable
Securities.




          3.1.7 Cooperation. The principal executive officer of the Company and all other officers and
members of the management of the Company shall cooperate fully in any offering of Registrable
Securities hereunder, which cooperation shall include, without limitation, the preparation of the
Registration Statement with respect to such offering and all other offering materials and related
documents, and participation in meetings with Underwriters, attorneys, accountants and




5









 




potential investors.




          3.1.8 Records. The Company shall make available for inspection by the holders of Registrable
Securities included in such Registration Statement, any Underwriter participating in any
disposition pursuant to such registration statement and any attorney, accountant or other
professional retained by any holder of Registrable Securities included in such Registration
Statement or any Underwriter, all financial and other records, pertinent corporate documents and
properties of the Company, as shall be necessary to enable them to exercise their due diligence
responsibility, and cause the Company’s officers, directors and employees to supply all information
requested by any of them in connection with such Registration Statement.




          3.1.9 Opinions and Comfort Letters. The Company shall furnish to each holder of Registrable
Securities included in any Registration Statement a signed counterpart, addressed to such holder,
of (i) any opinion of counsel to the Company delivered to any Underwriter and (ii) any comfort
letter from the Company’s independent public accountants delivered to any Underwriter. In the event
no legal opinion is delivered to any Underwriter, the Company shall furnish to each holder of
Registrable Securities included in such Registration Statement, at any time that such holder elects
to use a prospectus, an opinion of counsel to the Company to the effect that the Registration
Statement containing such prospectus has been declared effective and that no stop order is in
effect.




          3.1.10 Earnings Statement. The Company shall comply with all applicable rules and regulations
of the Commission and the Securities Act, and make available to its stockholders, as soon as
practicable, an earnings statement covering a period of twelve (12) months, beginning within three
(3) months after the effective date of the registration statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder.




          3.1.11 Listing. The Company shall use its reasonable best efforts to cause all Registrable
Securities included in any registration to be listed on such exchanges or otherwise designated for
trading in the same manner as similar securities issued by the Company are then listed or
designated or, if no such similar securities are then listed or designated, in a manner
satisfactory to the holders of a Majority-in-Interest of the Registrable Securities included in
such registration.




     3.2 Obligation to Suspend Distribution. Upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 3.1.4(iv), or, in the case of a resale
registration on Form S-3 pursuant to Section 2.3 hereof, upon any suspension by the Company,
pursuant to a written insider trading compliance program adopted by the Company’s Board of
Directors, of the ability of all “insiders” covered by such program to transact in the Company’s
securities because of the existence of material non-public information, each holder of Registrable
Securities included in any registration shall immediately discontinue disposition of such
Registrable Securities pursuant to the Registration Statement covering such Registrable Securities
until such holder receives the supplemented or amended prospectus contemplated by Section 3.1.4(iv)
or the restriction on the ability of “insiders” to transact in the Company’s securities is removed,
as applicable, and, if so directed by the Company, each such holder will deliver to the Company all
copies, other than permanent file copies then in such holder’s possession, of the most recent
prospectus covering such Registrable Securities at the time of receipt of such notice.



     3.3 Registration Expenses. The Company shall bear all costs and expenses incurred in
connection with any Demand Registration pursuant to Section 2.1, any Piggy-Back Registration
pursuant to Section 2.2, and any registration on Form S-3 effected pursuant to Section 2.3, and all
expenses incurred in performing or complying with its other obligations under this Agreement,
whether or not the Registration Statement becomes effective, including, without limitation: (i) all

expenses of any special experts retained by the Company in connection with such registration and
(ix) the fees and expenses of one legal counsel selected by the holders of a Majority-in-Interest
of the Registrable Securities included in such registration. The Company shall have no obligation
to pay any underwriting discounts or selling commissions attributable to the Registrable Securities
being sold by the holders thereof, which underwriting discounts or selling commissions shall be
borne by such holders. Additionally, in an underwritten offering, all selling stockholders and the
Company shall bear the expenses of the Underwriter pro rata in proportion to the respective amount
of shares each is selling in such offering.



     3.4 Information. The holders of Registrable Securities shall provide such information as may
reasonably be requested by the Company, or the managing Underwriter, if any, in connection with the
preparation of any Registration Statement, including amendments and supplements thereto, in order
to effect the registration of any Registrable Securities under the Securities Act pursuant to
Section 2 and in connection with the Company’s obligation to comply with federal and applicable
state securities laws.

Party”), from and against any expenses, losses, judgments, claims, damages or liabilities, whether
joint or several, arising out of or based upon any untrue statement (or allegedly untrue statement)
of a material fact contained in any Registration Statement under which the sale of such Registrable
Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or
summary prospectus contained in the Registration Statement, or any amendment or supplement to such
Registration Statement, or arising out of or based upon any omission (or alleged omission) to state
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 any rule or regulation
promulgated thereunder applicable to the Company and relating to action or inaction required of the
Company in connection with any such registration; and the Company shall promptly reimburse the
Investor Indemnified Party for any legal and any other expenses reasonably incurred by such
Investor Indemnified Party in connection with investigating and defending any such expense, loss,
judgment, claim, damage, liability or action; provided, however, that the Company will not be
liable in any such case to the extent that any such expense, loss, claim, damage or liability
arises out of or is based upon any untrue statement or allegedly untrue statement or omission or
alleged omission made in such Registration Statement, preliminary prospectus, final prospectus, or
summary prospectus, or any such amendment or supplement, in reliance upon and in conformity with
information furnished to the Company, in writing, by the selling holder with which such Investor
Indemnified Party is affiliated expressly for use therein. The Company also shall indemnify any
Underwriter of the Registrable Securities, their officers, affiliates, directors, partners, members
and agents and each Person who controls such Underwriter on substantially the same basis as that of
the indemnification provided above in this Section 4.1.



     4.2 Indemnification by Holders of Registrable Securities. Each selling holder of Registrable
Securities will, in the event that any registration is being effected under the Securities Act
pursuant to this Agreement of any Registrable Securities held by such selling holder, indemnify and
hold harmless the Company, each of its directors and officers and each underwriter (if any), and
each other selling holder and each other Person, if any, who controls another selling holder or
such underwriter within the meaning of the Securities Act, against any losses, claims, judgments,
damages or liabilities, whether joint or several, insofar as such losses, claims, judgments,
damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue
statement or allegedly untrue statement of a material fact contained in any Registration Statement
under which the sale of such Registrable Securities was registered under the Securities Act, any
preliminary prospectus, final prospectus or summary prospectus contained in the Registration
Statement, or any amendment or supplement to the Registration Statement, or arise out of or are
based upon any omission or the alleged omission to state a material fact required to be stated
therein or necessary to make the statement therein not misleading, if the statement or omission was
made in reliance upon and in conformity with information furnished in writing to the Company by
such selling holder expressly for use therein, and shall reimburse the Company, its directors and
officers, and each other selling holder or controlling Person for any legal or other expenses
reasonably incurred by any of them in connection with investigation or defending any such loss,
claim, damage, liability or action. Each selling holder’s indemnification obligations hereunder
shall be several and not joint and shall be limited to the amount of any net proceeds actually
received by such selling holder from the sale of Registrable Securities which gave rise to such
indemnification obligation.



     4.3 Conduct of Indemnification Proceedings. Promptly after receipt by any Person of any notice
of any loss, claim, damage or liability or any action in respect of which indemnity may be sought
pursuant to Section 4.1 or 4.2, such Person (the “Indemnified Party”) shall, if a claim in respect
thereof is to be made against any other Person for indemnification hereunder, notify such other
Person (the “Indemnifying Party”) in writing of the loss, claim, judgment, damage, liability or
action; provided, however, that the failure by the Indemnified Party to notify the Indemnifying
Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may
have to such Indemnified Party hereunder, except and solely to the extent the Indemnifying Party is
actually and materially prejudiced by such failure. If the Indemnified Party is seeking
indemnification with respect to any claim or action brought against the Indemnified Party, then the
Indemnifying Party shall be entitled to participate in such claim or action, and, to the extent
that it wishes, jointly with all other Indemnifying Parties, to assume control of the defense
thereof with counsel reasonably satisfactory to the Indemnified Party. After notice from the
Indemnifying Party to the Indemnified Party of its election to assume control of the defense of
such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any
legal or other expenses subsequently incurred by the Indemnified Party in connection with the
defense thereof other than reasonable costs of investigation; provided, however, that in any action
in which both the Indemnified Party and the Indemnifying Party are named as defendants, the
Indemnified Party shall have the right to employ separate counsel (but no more than one such
separate counsel) to represent the Indemnified Party and its controlling Persons who may be subject
to liability arising out of any claim in respect of which indemnity may be sought by the
Indemnified Party against the Indemnifying Party, with the fees and expenses of such counsel to be
paid by such Indemnifying Party if, based upon the written opinion of counsel of such Indemnified
Party, representation of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. No Indemnifying Party shall, without the prior written
consent of the Indemnified Party, consent to entry of judgment or effect any settlement of any
claim or pending or threatened proceeding in respect of which the Indemnified Party is or could
have been

a party and indemnity could have been sought hereunder by such Indemnified Party, unless such
judgment or settlement includes an unconditional release of such Indemnified Party from all
liability arising out of such claim or proceeding.



4.4 Contribution.




          4.4.1 If the indemnification provided for in the foregoing Sections 4.1, 4.2 and 4.3 is
unavailable to any Indemnified Party in respect of any loss, claim, damage, liability or action
referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified
Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such
loss, claim, damage, liability or action in such proportion as is appropriate to reflect the
relative fault of the Indemnified Parties and the Indemnifying Parties in connection with the
actions or omissions which resulted in such loss, claim, damage, liability or action, as well as
any other relevant equitable considerations. The relative fault of any Indemnified Party and any
Indemnifying Party 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 such Indemnified Party or such Indemnifying Party and the
parties’ relative intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.




          4.4.2 The parties hereto agree that it would not be just and equitable if contribution
pursuant to this Section 4.4 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 Section 4.4.1.




          4.4.3 The amount paid or payable by an Indemnified Party as a result of any loss, claim,
damage, liability or action referred to in the immediately preceding paragraph shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses incurred by such
Indemnified Party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 4.4, no holder of Registrable Securities shall be
required to contribute any amount in excess of the dollar amount of the net proceeds (after payment
of any underwriting fees, discounts, commissions or taxes) actually received by such holder from
the sale of Registrable Securities which gave rise to such contribution obligation. 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.




5. UNDERWRITING AND DISTRIBUTION.




     5.1 Rule 144. The Company covenants that it shall (a) file any reports required to be filed by
it under the Securities Act and the Exchange Act in order to maintain its status as a “reporting
issuer” under Rule 144(c)(1) under the Securities Act and (b) use commercially reasonable efforts
to obtain eligibility to use Form S-3, and shall take such further action as the holders of
Registrable Securities may reasonably request, all to the extent required from time to time to
enable such holders to sell Registrable Securities without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144 under the Securities Act, as such
Rules may be amended from time to time, or any similar Rule or regulation hereafter adopted by the
Commission.

shares of the Company’s capital stock in any registration filed by the Company for the sale of
shares of capital stock for its own account or for the account of any other Person. Each Pegasus
Party hereby agrees that it shall not cause the Company to file with the Commission a Registration

continuous basis pursuant to Rule 415 under the Securities Act at any time prior to the date that
is six (6) months from the date of this Agreement.



     6.2 Assignment; No Third Party Beneficiaries. This Agreement and the rights, duties and
obligations of the Company hereunder may not be assigned or delegated by the Company in whole or in
part. This Agreement and the rights, duties and obligations of the holders of Registrable
Securities hereunder may be freely assigned by such holder of Registrable Securities in conjunction
with and to the extent of any transfer by any holder of at least 1% of the Registrable Securities
outstanding at the time of such transfer to any party who signs a joinder agreement to this
Agreement in a form reasonably satisfactory to the Company. This Agreement and the provisions
hereof shall be binding upon and shall inure to the benefit of each of the parties hereto and their
respective successors and the permitted assigns of the Investor or holder of Registrable Securities
or of any assignee of the Investor or holder of Registrable Securities. This Agreement is not
intended to confer any rights or benefits on any Persons that are not party hereto other than as

Agreement. Waivers may be made in advance or after the right waived has arisen or the breach or

action at law, whether for specific performance of any term contained in this Agreement or for an
injunction against the breach of any such term or in aid of the exercise of any power granted in

actions, without being required to post a bond. None of the rights, powers or remedies conferred
under this Agreement shall be mutually exclusive, and each such right, power or remedy shall be
cumulative and in addition to any other right, power or remedy, whether conferred by this Agreement
or now or hereafter available at law, in equity, by statute or otherwise.

to this Agreement shall be brought and enforced in the courts of the State of New York or the
United States District Court for the Southern District of New York, and irrevocably submits to such
jurisdiction, which jurisdiction shall be exclusive. Each of the parties hereby waives any

RIGHT TO A TRIAL BY JURY IN ANY ACTION, SUIT, COUNTERCLAIM OR OTHER PROCEEDING (WHETHER BASED ON
