SECTION 2. REGISTRATION

2.1 REQUIRED REGISTRATION.

         (a) REGISTRATION STATEMENT. The Company shall use its reasonable best
efforts to prepare and file as promptly as practicable after the Effective Time
(as defined in the Merger Agreement) with the SEC a registration statement on
Form S-3 with respect to the Registrable Securities (the "REGISTRATION
STATEMENT") and to effect all such registrations, qualifications and compliances
(including, without limitation, obtaining appropriate qualifications under
applicable state securities or "blue sky" laws and compliance with any other
applicable governmental requirements or regulations) as any Holder may
reasonably request and that would permit or facilitate the sale of Registrable
Securities in the open market (provided, however, that the Company shall not be
required in connection therewith to qualify to do business or to file a


                                       2
<Page>

general consent to service of process in any such state or jurisdiction), and
shall use its reasonable best efforts so that such Registration Statement and
all other such registrations, qualifications and compliances may become
effective no later than ninety (90) days following the Effective Time.
Notwithstanding the foregoing, the Company shall not be obligated to effect an
underwritten registration statement.

         (b) EFFECTIVENESS, SUSPENSION RIGHT.

         (i) The Company will use its reasonable best efforts to maintain the
effectiveness of the Registration Statement and other applicable registrations,
qualifications and compliances for up to two (2) years from the Effective Time
(the "REGISTRATION EFFECTIVE PERIOD"), and from time to time will amend or
supplement the Registration Statement and the prospectus contained therein as
and to the extent necessary to comply with the Securities Act, the Exchange Act
and any applicable state securities statute or regulation, subject to the
following limitations and qualifications.

         (ii) Following the date on which the Registration Statement is first
declared effective, the Holders will be permitted (subject in all cases to
Section 2.2 below) to offer and sell Registrable Securities during the
Registration Effective Period in the manner described in the Registration
Statement, provided that the Registration Statement remains effective and has
not been suspended, and provided further that until the first anniversary of the
Effective Time, no Holder shall be permitted to sell Registrable Securities in
excess of the number of Registrable Securities that such Holder would be
entitled to sell under subsection (e) of Rule 144 if the Registrable Securities
were "restricted securities" as defined in Rule 144 (assuming for such purpose
(and for the avoidance of doubt) that one year has elapsed since the Effective
Time and accordingly the volume requirements under subsection (e) of Rule 144
are immediately applicable to the Holders). No such volume limitation shall
apply to any Holder after the first anniversary of the Effective Time;

         (iii) Notwithstanding any other provision of this Section 2.1 but
subject to Section 2.2, the Company shall have the right at any time (but only
five times during the term of this Agreement and no more than three times in any
twelve-month period) to require that all Holders suspend further open market
offers and sales of Registrable Securities whenever, and only if, in the
reasonable good faith judgment of the Company after receipt of advice from
outside counsel there is or there is reasonably likely to be in existence
material undisclosed information or events with respect to the Company (the
"SUSPENSION RIGHT"). In the event the Company exercises the Suspension Right,
such suspension will continue only for the period of time reasonably necessary
for disclosure to occur at a time that is not detrimental to the Company or its
stockholders or until such time as the information or event is no longer
material (but in no event more than 30 days), each as determined in good faith
by the Company after receipt of advice from outside counsel. The Company will
promptly give the Holders notice of any such suspension and will use all
reasonable efforts to minimize the length of the suspension.

2.2 PROCEDURE FOR SALE OF SHARES UNDER REGISTRATION STATEMENT.

         (a) DELIVERY OF PROSPECTUS. For any offer or sale of any of the
Registrable Securities


                                       3
<Page>

by a Holder in a transaction that is not exempt under the Securities Act, the
Holder, in addition to complying with any other federal securities laws, shall
deliver a copy of the final prospectus (or amendment of or supplement to such
prospectus) of the Company covering the Registrable Securities in the form
furnished to the Holder by the Company to the purchaser of any of the
Registrable Securities on or before the settlement date for the purchase of such
Registrable Securities.

         (b) COPIES OF PROSPECTUSES. The Company shall furnish to each Holder a
reasonable number of copies of the final prospectus (or amendment of or
supplement to such prospectus) of the Company covering the Registrable
Securities as may be necessary so that, as thereafter delivered to the
purchasers of such Registrable Securities, such prospectus shall not as of the
date of delivery to the Holder include an untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements therein not misleading or incomplete in the light of the
circumstances then existing, in each case exclusive of information supplied by
such Holder expressly for inclusion in the Registration Statement.

         2.3      PIGGYBACK REGISTRATIONS.

                  (a) The Company shall notify all Holders in writing at least
         thirty (30) days prior to the filing of any registration statement
         under the Securities Act for purposes of a public offering of
         securities of the Company (including, but not limited to, registration
         statements relating to offerings of securities of the Company for the
         account of stockholders of the Company, but excluding the Registration
         Statement and registration statements on Forms S-4 and S-8) and will
         offer to include in such registration statement all of such Registrable
         Securities held by such Holder. If the registration statement under
         which the Company gives notice under this Section 2.3 is for an
         underwritten offering, the Company shall so advise the Holders in such
         notice. Each Holder desiring to include in any such registration
         statement all or any part of the Registrable Securities held by it
         shall, within fifteen (15) days after receipt of the above-described
         notice from the Company, so notify the Company in writing, provided
         that until the first anniversary of the Effective Time, no Holder shall
         be permitted to sell Registrable Securities in excess of the number of
         Registrable Securities that such Holder would be entitled to sell under
         subsection (e) of Rule 144 if the Registrable Securities were
         "restricted securities" as defined in Rule 144 (assuming for such
         purpose (and for the avoidance of doubt) that one year has elapsed
         since the Effective Time and accordingly the volume requirements under
         subsection (e) of Rule 144 are immediately applicable to the Holders).
         No such volume limitation shall apply to any Holder after the first
         anniversary of the Effective Time. If a Holder decides not to include
         all of its Registrable Securities in any registration statement
         thereafter filed by the Company, such Holder shall nevertheless
         continue to have the right to include any Registrable Securities in any
         subsequent registration statement or registration statements as may be
         filed by the Company with respect to offerings of its securities, all
         upon the terms and conditions set forth herein.

                  (b) If the registration statement under which the Company
         gives notice under this Section 2.3 is for an underwritten offering,
         and the managing underwriters advise the Company in writing that in
         their opinion the number of securities requested to be included in such
         registration (i) creates a substantial risk that the price per share in
         such


                                       4
<Page>

         registration will be materially and adversely affected, or (ii) exceeds
         the number which can be reasonably sold in such offering, then the
         number of shares that may be included in the underwriting shall be
         allocated, first, to the Company if the Company, and not a stockholder,
         initiated the filing of the registration statement; second, to the
         Holders on a pro rata basis based on the total number of Registrable
         Securities held by the Holders desiring to participate in the
         registration and underwriting pursuant to the terms of this Section
         2.3; and third, to any other stockholder of the Company participating
         in such underwritten offering on a pro rata basis based on the number
         of shares that all such stockholders desire to register.

                  (c) RIGHT TO TERMINATE REGISTRATION. The Company shall have
         the right to terminate or withdraw any registration initiated by it
         under this Section 2.3 prior to the effectiveness of such registration
         whether or not any Holder has elected to include Registrable Securities
         in such registration. The Registration Expenses of such withdrawn
         registration shall be borne by the Company in accordance with Section
         2.4 hereof.

         2.4 EXPENSES OF REGISTRATION. Except as provided herein, all
Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to Section 2.1 or any registration under
Section 2.3 herein shall be borne by the Company. All Selling Expenses incurred
in connection with any registrations hereunder shall be borne by the holders of
the securities so registered pro rata on the basis of the number of shares so
registered.

         2.5 TERMINATION OF REGISTRATION RIGHTS. All registration rights granted
under this Section 2 shall terminate and be of no further force and effect upon
the second anniversary of the Effective Time.

         2.6 DELAY OF REGISTRATION; FURNISHING INFORMATION. It shall be a
condition precedent to the obligations of the Company to take any action
pursuant to Section 2.1 or 2.3 that the selling Holders shall furnish to the
Company such information regarding themselves, the Registrable Securities held
by them and the intended method of disposition of such securities as reasonably
shall be required to effect the registration of their Registrable Securities.

         2.7 INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement under Section 2.1 or 2.3:

                  (a) To the extent permitted by law, the Company will indemnify
         and hold harmless each Holder, the partners, members, officers and
         directors of each Holder, any underwriter (as defined in the Securities
         Act) and each person, if any, who controls such Holder or underwriter
         within the meaning of the Securities Act or the Exchange Act, against
         any losses, claims, damages, or liabilities (joint or several) to which
         they may become subject under the Securities Act, the Exchange Act or
         other federal or state law, insofar as such losses, claims, damages or
         liabilities (or actions in respect thereof) arise out of or are based
         upon any of the following statements, omissions or violations
         (collectively a "VIOLATION") by the Company: (i) any untrue statement
         or alleged untrue statement of a material fact contained in such
         registration statement, including any preliminary prospectus or final
         prospectus contained therein or any amendments or


                                       5
<Page>

         supplements thereto, (ii) the omission or alleged omission to state
         therein a material fact required to be stated therein, or necessary to
         make the statements therein not misleading, or (iii) any violation or
         alleged violation by the Company of the Securities Act, the Exchange
         Act, any state securities law or any rule or regulation promulgated
         under the Securities Act, the Exchange Act or any state securities law
         in connection with the offering covered by such registration statement;
         and the Company will promptly reimburse to each such Holder, partner,
         member, officer, director, underwriter or controlling person for any
         legal or other expenses reasonably incurred by them in connection with
         investigating or defending any such loss, claim, damage, liability or
         action; PROVIDED HOWEVER, that the indemnity agreement contained in
         this Section 2.7(a) shall not apply to amounts paid in settlement of
         any such loss, claim, damage, liability or action if such settlement is
         effected without the consent of the Company, which consent shall not be
         unreasonably withheld, nor shall the Company be liable in any such case
         for any such loss, claim, damage, liability or action to the extent
         that it arises out of or is based upon a Violation which occurs in
         reliance upon and in conformity with information furnished expressly
         for use in connection with such registration by such Holder, partner,
         member, officer, director, underwriter or controlling person of such
         Holder.

                  (b) To the extent permitted by law, each Holder severally and
         not jointly will, if Registrable Securities held by such Holder are
         included in the securities as to which such registration is being
         effected, indemnify and hold harmless the Company, each of its
         directors, its officers and each person, if any, who controls the
         Company within the meaning of the Securities Act, any underwriter and
         any other Holder selling securities under such registration statement
         or any of such other Holder's partners, members, directors or officers
         or any person who controls such Holder, against any losses, claims,
         damages or liabilities (joint or several) to which the Company or any
         such director, officer, controlling person, underwriter or other such
         Holder, or partner, member, director, officer or controlling person of
         such other Holder may become subject under the Securities Act, the
         Exchange Act or other federal or state law, insofar as such losses,
         claims, damages or liabilities (or actions in respect thereto) arise
         out of or are based upon any Violation, in each case to the extent (and
         only to the extent) that such Violation occurs in reliance upon and in
         conformity with information furnished by such Holder to the Company
         expressly for use in connection with such registration; and each such
         Holder will promptly reimburse to the Company or any such director,
         officer, controlling person, underwriter or other Holder, or partner,
         member, officer, director or controlling person of such other Holder
         any legal or other expenses reasonably incurred by such party in
         connection with investigating or defending any such loss, claim,
         damage, liability or action if it is judicially determined that there
         was such a Violation; provided, however, that the indemnity agreement
         contained in this Section 2.7(b) shall not apply to amounts paid in
         settlement of any such loss, claim, damage, liability or action if such
         settlement is effected without the consent of the Holder, which consent
         shall not be unreasonably withheld; provided further, that in no event
         shall any indemnity under this Section 2.7 exceed the net proceeds from
         the offering received by such Holder.

                  (c) Promptly after receipt by an indemnified party under this
         Section 2.7 of notice of the commencement of any action (including any
         governmental action), such


                                       6
<Page>

         indemnified party will, if a claim in respect thereof is to be made
         against any indemnifying party under this Section 2.7, deliver to the
         indemnifying party a written notice of the commencement thereof and the
         indemnifying party shall have the right to participate in, and, to the
         extent the indemnifying party so desires, jointly with any other
         indemnifying party similarly noticed, to assume the defense thereof
         with counsel mutually satisfactory to the parties; provided, however,
         that an indemnified party shall have the right to retain its own
         counsel, with the fees and expenses to be paid by the indemnifying
         party, if, upon written advice of counsel, representation of such
         indemnified party by the counsel retained by the indemnifying party
         would be inappropriate due to actual or potential differing interests
         between such indemnified party and any other party represented by such
         counsel in such proceeding. If an indemnified party fails to deliver
         written notice to the indemnifying party within a reasonable time after
         the indemnified party's receipt of notice of the commencement of any
         such action, the indemnifying party's liability under this Section 2.7
         shall be reduced to the extent such failure to notify was prejudicial
         to the indemnifying party's ability to defend such action, but the
         omission to so deliver written notice to the indemnifying party will
         not relieve it of any liability that it may have to any indemnified
         party otherwise than under this Section 2.7.

                  (d) If the indemnification provided for in this Section 2.7 is
         held by a court of competent jurisdiction to be unavailable to an
         indemnified party with respect to any losses, claims, damages or
         liabilities referred to herein, the indemnifying party, in lieu of
         indemnifying such indemnified party thereunder, shall to the extent
         permitted by applicable law contribute to the amount paid or payable by
         such indemnified party as a result of such loss, claim, damage or
         liability in such proportion as is appropriate to reflect the relative
         fault of the indemnifying party on the one hand and of the indemnified
         party on the other in connection with the Violation(s) that resulted in
         such loss, claim, damage or liability, as well as any other relevant
         equitable considerations. The relative fault of the indemnifying party
         and of the indemnified party shall be determined by a court of law by
         reference to, among other things, whether the untrue or alleged untrue
         statement of a material fact or the omission to state a material fact
         relates to information supplied by the indemnifying party or by the
         indemnified party and the parties' relative intent, knowledge, access
         to information and opportunity to correct or prevent such statement or
         omission; PROVIDED, that in no event shall any contribution by a Holder
         hereunder exceed the net proceeds from the offering received by such
         Holder.

                  (e) The obligations of the Company and Holders under this
         Section 2.7 shall survive completion of any offering of Registrable
         Securities in a registration statement and the termination of this
         Agreement. No indemnifying party, in the defense of any such claim or
         litigation, shall, except with the consent of each indemnified party,
         consent to entry of any judgment or enter into any settlement which
         does not include as an unconditional term thereof the giving by the
         claimant or plaintiff to such indemnified party of a complete release
         from all liability in respect to such claim or litigation without any
         admission of guilt or wrongdoing.

         2.8 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the Company
to register Registrable Securities pursuant to this Section 2 may be assigned by
a Holder to a transferee of Registrable Securities that is: (a) the estate of
such Holder, or the spouse, siblings or lineal descendants of such Holder, or
such Holder's spouse's siblings or lineal descendants or trusts for the benefit
of any of the foregoing; (b) a stockholder, partner, retired partner who retires
after the date hereof, limited partner, retired limited partner who retires
after the date hereof, member, or retired member who retires after the date
hereof of such Holder; (c) a corporation, partnership, limited liability
company, joint venture, trust or individual who or which, directly or indirectly
through one or more intermediaries, is controlled by or under common control
with such Holder or which controls, directly or indirectly through one or more
intermediaries, such Holder; (d) a trust for the benefit of, or partnership,
corporation, limited liability company or other entity owned or controlled by,
any of the foregoing; or (e) any other transferee of all, but not less than all,
of such Holder's Registrable Securities; PROVIDED, HOWEVER, (i) the transferor
shall, within ten (10) days after such transfer, furnish to the Company 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 become a party to and be subject to all restrictions
set forth in this Agreement. For purposes of this Section 2.8, the terms
"CONTROL", "CONTROLLED" and "COMMON CONTROL WITH" mean the ability, whether by
the direct or indirect ownership of voting securities or other equity interest,
by contract or otherwise, to elect a majority of the directors of a corporation,
to select the managing or general partner of a partnership or limited
partnership, respectively, or otherwise to select a majority of those persons
exercising governing authority over an entity. Notwithstanding the foregoing and
for the avoidance of doubt, a pledge, collateral assignment or other similar
arrangement shall not be restricted under this Agreement in any manner and
neither the Holder nor the secured party (or creditor) party to such pledge,
collateral assignment or other similar arrangement shall be required to comply
with the provisions of the immediately preceding proviso in the absence of a
foreclosure or other realization of collateral with respect to such pledge,
collateral assignment or other similar arrangement.

         2.9 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
