                             STOCKHOLDERS AGREEMENT

            This Stockholders Agreement (this "Agreement") is entered into as of
April 17, 2007 by and among Evergreen Solar, Inc., a corporation organized and
existing under the laws of the State of Delaware (the "Company"), and DC
Chemical Co., Ltd., a Korean company (the "Purchaser"). Capitalized terms used
herein without definition are defined in Section 12.

                                    RECITALS

            A. The Purchaser is purchasing 3,000,000 shares of Common Stock, 625
shares of Restricted Preferred Stock and 4,500,000 shares of Restricted Common
Stock (together, the "Shares") pursuant to that certain Stock Purchase Agreement
dated as of April 17, 2007 (the "Stock Purchase Agreement");

            B. The Purchaser has made certain requests, including for approval,
for purposes of Section 203 of the Delaware General Corporation Law (including
any successor statute thereto "Section 203") of the transactions pursuant to
which the Purchaser will become, together with its Affiliates, an "interested
stockholder" within the meaning of Section 203;

            C. The Board has determined that it is in the best interests of the
Company and its stockholders to (i) issue and sell the Shares to the Purchaser
and (ii) approve, for purposes of Section 203, the transactions pursuant to
which the Purchaser will become an "interested stockholder" within the meaning
of Section 203; and

            D. The Company and the Purchaser desire to make certain covenants
and agreements with one another pursuant to this Agreement.

            NOW THEREFORE, in consideration of the covenants and promises set
forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as
follows:

      1. Covenants of the Purchaser.

      1.1 Standstill. During the Standstill Period, the Purchaser shall not,
without the prior written consent of the Company or the Board:

            (a) acquire, offer, seek or propose to acquire, or agree to acquire,
      directly or indirectly (including acquiring beneficial ownership as
      defined in Rule 13d-3 under the Exchange Act), by purchase or otherwise,
      any Voting Stock or direct or indirect rights to acquire any Voting Stock,
      or any assets of the Company or of any successor to or person in control;

<PAGE>

            (b) make, or in any way participate in any "solicitation" of
      "proxies" to vote in favor of (as such terms are used in the rules of the
      SEC), or seek to advise or influence any person or entity with respect to,
      proposals which have not been approved or recommended by the Board;

            (c) make any public announcement regarding or submit a proposal for
      or offer of (with or without conditions) (including to the Board), any
      extraordinary transaction which, if approved and consummated, would result
      in a Sale Transaction;

            (d) form, join or in any way participate in a 13D Group in
      connection with any of the foregoing;

            (e) deposit any Voting Stock in a voting trust or subject them to
      any voting arrangements;

            (f) vote or agree to vote in concert with any other person or 13D
      Group for the purpose of acquiring, holding or disposing of Voting Stock
      for the purpose of seeking to control the Board or the management of the
      company; or

            (g) direct or instruct any of its Subsidiaries, Representatives or
      Affiliates to take any of the foregoing actions.

      Notwithstanding the foregoing, this Section 1 shall not apply to
transactions between and among the (i) the Company and the Purchaser (including
purchases of securities pursuant to the Stock Purchase Agreement, or Section 3
hereof) and (ii) the Purchaser and its Affiliates.

      Notwithstanding the foregoing, if, at any time during the Standstill
Period, any of the following (each a "Standstill Early Termination Event")
occurs, the Standstill Period shall be terminated:

            (i) any person or 13D Group (other than any person or 13D Group
      which includes the Purchaser, its Subsidiaries, Representatives or
      Affiliates) has made an offer to acquire beneficial ownership of Voting
      Stock representing 35% or more of the then outstanding Voting Stock;

            (ii) the Company enters into any merger, sale or other business
      combination transaction pursuant to which the outstanding shares of Common
      Stock would be converted into cash and/or securities and/or property of
      another Person or 13D Group (other than any Person or 13D Group which
      includes the Purchaser, its Subsidiaries or Representatives) such that (x)
      any such Person or 13D Group acquires beneficial ownership of Voting Stock
      representing 30% or more of the then outstanding Voting Stock; or (y) 50%
      or more of the outstanding shares of Common Stock as of immediately prior
      to such transaction would be owned by Persons other than the then current
      holders of shares of Common Stock and any Person or 13D Group which
      includes the Purchaser, its Subsidiaries or Representatives;

                                       2
<PAGE>

            (iii) the Company enters into any agreement to sell all or
      substantially all of its material assets;

            (iv) the Purchaser and its Affiliates no longer hold Voting Stock
      representing at least 5% of the Voting Stock then issued and outstanding;
      or

            (v) a Sale Transaction closes.

      1.2. Conversion of Restricted Preferred Stock; Transfer Restrictions.

            (a) If a Conversion Event occurs before the Transfer Restriction
      Lapse Date, the Common Stock into which each share of Restricted Preferred
      Stock converts shall be deemed to be Restricted Common Stock.

            (b) Except for Permitted Transfers, the Purchaser shall not (and
      shall not permit any Affiliate to), directly or indirectly sell, transfer,
      pledge, contract to sell, sell any option or contract to purchase,
      purchase any option or contract to sell, grant any option, right or
      warrant to purchase, transfer the economic risk of ownership of, or
      otherwise dispose of (each a "Transfer") in any single or series of
      related transactions Voting Stock or Voting Power to any person who, after
      consummation of such Transfer would have beneficial ownership of Voting
      Stock representing in the aggregate 10% or more of Voting Power.

            (c) Except for Transfers to Affiliates, the Purchaser shall not (and
      shall not permit any Affiliate to), directly or indirectly, effect any
      Transfer of Restricted Common Stock or Restricted Preferred Stock until
      the Transfer Restriction Lapse Date without the prior written approval of
      the Board.

      2. Prohibited Transfer.

      (a) Any transfer in violation of the terms of Section 1.2 above
("Prohibited Transfer") shall not be effected by the Company and shall be
voidable at the option of the Company by its giving written notice to the
Purchaser and the proposed transferee. Each certificate representing Voting
Stock held by the Purchaser shall be endorsed by the Company with a legend
reading as follows:

      "THE SHARES EVIDENCED HEREBY ARE SUBJECT TO A STOCKHOLDERS AGREEMENT BY
      AND BETWEEN THE COMPANY AND THE HOLDER HEREOF (A COPY OF WHICH MAY BE
      OBTAINED FROM THE COMPANY) (THE "STOCKHOLDERS AGREEMENT"), AND NO TRANSFER
      OF THE SHARES EVIDENCED HEREBY SHALL BE EFFECTIVE EXCEPT IN COMPLIANCE
      WITH THE TERMS THEREOF."

      (b) Each certificate representing Restricted Common Stock and Restricted
Preferred Stock shall be endorsed by the Company with an additional legend
reading as follows:

                                       3
<PAGE>

      "THE SHARES EVIDENCED HEREBY ARE SHARES OF RESTRICTED [PREFERRED] [COMMON]
      STOCK, AND UNTIL THE TRANSFER RESTRICTION LAPSE DATE (AS DEFINED IN THE
      STOCKHOLDERS AGREEMENT) MAY NOT BE TRANSFERRED (AS DEFINED IN THE
      STOCKHOLDERS AGREEMENT) UNLESS SUCH TRANSFER IS APPROVED IN ADVANCE IN
      WRITING BY THE BOARD OF DIRECTORS OF THE COMPANY."

      (c) On the Transfer Restriction Lapse Date or with the prior written
approval of the Board, in exchange for the surrender by the Purchaser of one or
more certificates representing (i) Restricted Common Stock, the Company shall
issue and deliver to the Purchaser new certificates representing the same number
of new shares of Common Stock as the number of Restricted Common Stock
represented by such certificates and (ii) Restricted Preferred Stock, the
Company shall issue and deliver to the Purchaser new certificates representing
the same number of new shares of Preferred Stock as the number of Restricted
Preferred Stock represented by such certificates, in each case, without the
legend set forth in Section 2(b).

      3. Pre-emptive Rights.

      3.1. The Company hereby grants to the Purchaser the right to purchase its
share of New Securities that the Company may, from time to time, propose to sell
and issue in each bona fide, underwritten public offering (provided that such
public offering constitutes a "public offering" under the rules and regulations
of the Nasdaq Global Market) (each, a "Public Offering"). The Company may seek
an interpretive letter (a "Nasdaq Letter") from the Nasdaq Global Market on the
issue of whether such sale constitutes a Public Offering. Such share, for the
purposes of this pre-emptive right, is the amount described in Section 3.3

      3.2. In the event that the Company proposes to undertake a Public
Offering, it shall give the Purchaser written notice (the "Company Notice") of
its intention, describing the type of New Securities, the preliminary price
range (promptly when available) and the general terms upon which the Company
proposes to issue the same (promptly when available). When the final terms and
conditions (including the price) of the New Securities are determined, the
Purchaser shall be so notified and shall have the right to purchase the
Purchaser's share of the New Issuance as determined by Section 3.3 through the
underwriters of such Public Offering, at the price and upon the same terms and
conditions as the other purchasers purchasing New Securities in the Public
Offering.

      3.3. The Purchaser's share of New Securities in a Public Offering shall be
determined by multiplying the aggregate number of the New Securities that the
Company proposes to issue and sell by a fraction, the numerator of which is the
number of Shares held by the Purchaser immediately prior to the issuance of the
New Securities and the denominator of which is the aggregate number of
outstanding shares of Common Stock and Series B Preferred Stock immediately
prior to the issuance of the New Securities. The sale to the Purchaser of New
Securities shall occur

                                       4
<PAGE>

contemporaneously with the sale to the other purchasers of New Securities. The
Company may abandon its plan to sell the New Securities notwithstanding the
Purchaser's intention to exercise its pre-emptive rights hereunder.

      3.4. In the event that the Company sells and issues any New Securities in
a manner which does not constitute a Public Offering (each transaction, a
"Non-Public Offering"), the following provisions shall apply:

            (a) On the consummation of a Non-Public Offering, the Company shall
      grant the Purchaser the right to purchase (the "Make-up Purchase") all or
      some of that number of New Securities required for the Purchaser to, after
      giving effect to the Make-up Purchase, maintain its Percentage of
      Ownership interest in the Company, at the price and upon the same terms
      and conditions as such Non-Public Offering; and

            (b) The exercise of the Purchaser's rights under this Section 3.4
      shall be conditioned on the receipt of a Nasdaq Letter stating that any
      purchase of New Securities by the Purchaser pursuant to the pre-emptive
      right in this Section 3.4 shall not require the approval of the
      stockholders of the Company, unless counsel for the Company determine such
      Nasdaq Letter to be unnecessary in order to consummate the transaction.

            (c) For the purposes of this Section 3.4, "Percentage of Ownership"
      shall mean the number, expressed as a percentage, equal to the number of
      securities held by the Purchaser immediately prior to the issuance of the
      New Securities in such Non-Public Offering divided by the aggregate number
      of outstanding shares of Common Stock and Series B Preferred Stock
      immediately prior to such issuance.

      3.5. Notwithstanding anything to the contrary, in no event may the
Purchaser acquire New Securities pursuant to these pre-emptive rights to the
extent that the purchase of such New Securities would constitute a change of
control of the Company, as provided by the rules and regulations of the Nasdaq
Global Market.

      3.6. The preemptive rights provided in this Section 3 shall terminate on
the earliest of (a) the seventh anniversary of the date hereof, (b) the date the
Purchaser no longer holds at least 10,000,000 shares of Common Stock of the
Company (on an as converted basis and as adjusted for stock splits, combinations
and the like), and (c) the termination of the Supply Agreement pursuant to
Section 8.2(d) thereof.

      4. Registrations Upon Request.

      4.1. Requests by The Purchaser.

      (a) Shelf Registration. The Company shall use its commercially reasonable
efforts to file, within (i) with respect to the Common Stock purchased at the
Closing, fifteen days of the Closing and (ii) with respect to the Restricted
Common Stock and Restricted Preferred Stock, within fifteen days after the
Transfer Restriction Lapse Date

                                       5
<PAGE>

or the date on which the Board removes the Transfer Restriction in respect of
such Restricted Common Stock or Restricted Preferred Stock, an automatic shelf
registration statement on Form S-3 (each an "Initial Automatic Shelf
Registration Statement") in accordance with the requirements of the Securities
Act and the rules and regulations of the Commission thereunder, which shall
become effective upon filing with the Commission pursuant to Rule 462(e) under
the Securities Act, which shall contain a prospectus in such form to permit the
Purchaser to sell all Registrable Securities at any time beginning on or after
the effective date thereof pursuant to Rule 415 under the Securities Act or any
successor or similar rule that may be adopted by the Commission. If the Company
is not eligible to use an automatic shelf registration statement at any time of
determination of eligibility, the Company shall promptly (but in any event
within 30 days) post-effectively amend the Initial Automatic Shelf Registration
Statement (or any Subsequent Automatic Shelf Registration Statement (as defined
below)) or file a new registration statement on a Form S-3, in either case so to
permit the Purchaser to sell all Registrable Securities pursuant to Rule 415
under the Securities Act or any successor or similar rule that may be adopted by
the Commission. The term "Shelf Registration Statement" as used herein shall
mean the Initial Automatic Shelf Registration Statements (or any Subsequent
Automatic Shelf Registration Statement) or any post-effective amendment thereto
or a new registration statement so filed pursuant to this Section 4.1(a). No
other stockholder of the Company shall have any right to include his, her or its
securities of the Company for resale under the Shelf Registration Statement.
Upon any Shelf Registration Statement having been filed:

            (i) the Company shall use its commercially reasonable efforts to
      keep such Shelf Registration Statement continuously effective in order to
      permit the prospectus included therein to be usable by the holders of
      Registrable Securities until the earlier of (w) such time as all
      Registrable Securities that could be sold under such Shelf Registration
      Statement have been sold or are no longer outstanding and (x) three years
      from the date of filing thereof; provided that if, at the expiration of
      such three-year period, any Registrable Securities remain outstanding and
      eligible for registration under the terms of this Agreement, the Company
      shall use its commercially reasonable efforts to file on the date of
      expiration of such three-year period a new automatic shelf registration
      statement on Form S-3 (each a "Subsequent Automatic Shelf Registration
      Statement") in accordance with the requirements of the Securities Act and
      the rules and regulations of the Commission thereunder, which shall
      contain a prospectus in such form to permit the Purchaser to sell all
      Registrable Securities at any time beginning on or after the effective
      date thereof pursuant to Rule 415 under the Securities Act or any
      successor or similar rule that may be adopted by the Commission, and to
      keep such Subsequent Automatic Shelf Registration Statement effective
      until the earlier of (y) such time as all such Registrable Securities have
      been sold, are no longer eligible for registration under the terms of this
      Agreement or are no longer outstanding and (z) three years from the date
      of filing of the Subsequent Automatic Shelf Registration Statement;

                                       6
<PAGE>

            (ii) the Company shall pay the registration fee for all Registrable
      Securities at the time of filing of the first Shelf Registration Statement
      pursuant to clause (i) of this Section 3.2 and shall not elect to pay any
      portion of the registration fee on a deferred basis; provided that, in
      connection with any new registration statement filed after the Initial
      Automatic Shelf Registration Statements pursuant to this Section 3.2,
      including any Subsequent Automatic Shelf Registration Statement, the
      Company shall carry forward the registration fee for any unsold
      Registrable Securities pursuant to Rule 457(p) (or any successor rule)
      under the Securities Act;

            (iii) if at any time following the filing of any Shelf Registration
      Statement, the Purchaser desires to sell all or any portion of the
      Registrable Securities under such Shelf Registration Statement in an
      underwritten offering, the Purchaser shall notify the Company of such
      intent at least 20 business days prior to any such sale (any such proposed
      sale, an "Underwritten Take-Down Transaction"), and the Company shall
      prepare and file a prospectus supplement, post-effective amendment to the
      Shelf Registration Statement and/or Exchange Act reports incorporated by
      reference into the Shelf Registration Statement and take such other
      actions as necessary to permit the consummation of any such Underwritten
      Take-Down Transaction;

            (iv) a request for an Underwritten Take-Down Transaction for which a
      "road show" is conducted shall be deemed a request made pursuant to
      Section 4.1(b) if such Underwritten Take-Down Transaction is consummated
      as to substantially all of the Registrable Securities requested by the
      Purchaser to be disposed of in such Underwritten Take-Down Transaction;
      and

            (v) for the avoidance of doubt, the sale of Registrable Securities
      under a Shelf Registration Statement not involving a "road show", whether
      in an Underwritten Take-Down Transaction or pursuant to an offering that
      is not underwritten, shall not be deemed a request made pursuant to
      Section 4.1(b).

      (b) Notice of Request. At any time and from time to time, except at any
time during which a Shelf Registration Statement pursuant to Section 4.1(a) is
effective, available for the offer and sale of Registrable Securities, and not
subject to any stop order, injunction, or other order or requirement of the
Commission or other governmental agency or court (such period, a "Shelf
Effectiveness Period"), the Purchaser shall have the right to make up to six
requests that the Company effect the registration under the Securities Act of
all or a portion of the Registrable Securities owned by the Purchaser, each such
request to specify the intended method or methods of disposition thereof, which
shall include an underwritten offering. Upon any such request, the Company shall
use its commercially reasonable efforts to effect the prompt registration under
the Securities Act of the Registrable Securities which the Company has been so
requested to register by the Purchaser in accordance with the intended method or
methods of disposition of the Purchaser. Notwithstanding anything to the
contrary herein, a request pursuant to this Section 4.1(b) shall not count as a
request for purposes of this Section 4.1(b) unless a registration statement with
respect thereto has

                                       7
<PAGE>

become effective and has been kept continuously effective for a period of at
least 180 days (or such shorter period ending on the date on which all the
Registrable Securities covered by such registration statement have been sold
pursuant thereto) or, if such registration statement relates to an underwritten
offering, such longer period as in the opinion of counsel for the underwriter or
underwriters a prospectus is required by law to be delivered in connection with
sales of Registrable Securities by an underwriter or dealer. Should a
registration statement not become effective, or should an Underwritten Take-Down
Transaction for which a "road show" is conducted not be consummated, in either
case due to the failure of the Purchaser to perform its obligations under this
Agreement in any material respect, or in the event the Purchaser withdraws or
does not pursue its request for registration, or an Underwritten Take-Down
Transaction for which a "road show" is conducted, as provided in Section 4.2
below (in each of the foregoing cases, provided that at such time the Company is
in compliance in all material respects with its obligations under this
Agreement), the related request shall count as a request for purposes of this
Section 4.1(b); provided that if (i) the registration statement does not become
effective, or such Underwritten Take-Down Transaction for which a "road show" is
conducted is not consummated, because a material adverse change has occurred, or
is reasonably likely to occur, in the condition (financial or otherwise),
prospects, business, assets or results of operations of the Company and its
subsidiaries taken as a whole subsequent to the date of the delivery of the
notice requesting such registration, (ii) after the registration statement has
become effective, such registration, or such Underwritten Take-Down Transaction
for which a "road show" is conducted, is terminated as a result of any stop
order, injunction, or other order or requirement of the Commission or other
governmental agency or court, or (iii) the Purchaser reimburses the Company for
any and all Registration Expenses incurred by the Company in connection with
such request for registration, or in connection with such Underwritten Take-Down
Transaction for which a "road show" is conducted, that was withdrawn or not
pursued, the related request shall not count as a request for purposes of this
Section 4.1(b).

      4.2. Withdrawal of Requests. The Purchaser shall have the right,
exercisable by written notice to the Company, to withdraw any request for an
Underwritten Take-Down Transaction or to effect the registration of Registrable
Securities owned by the Purchaser pursuant to Section 4.1(b); provided that in
the case of a request pursuant to Section 4.1(b), the Purchaser shall have such
right only at any time prior to the effective date of the related registration
statement. Upon receipt of a notice from the Purchaser to such effect, the
Company shall cease all efforts to obtain effectiveness of the applicable
registration statement or effectuate the Underwritten Take-Down Transaction, as
the case may be.

      4.3. Deferral. Notwithstanding the foregoing, but subject to the
immediately following sentence, the Company may delay by up to 60 consecutive
days, as appropriate (the "Delay Period") the filing dates of the Initial
Automatic Shelf Registration Statements and following the effective dates
thereof , the Company may, from time to time, suspend the effectiveness of such
Initial Automatic Shelf Registration Statement for up to 60 consecutive days, as
appropriate (a "Suspension Period"), in each case by giving written notice to
the Purchaser, if the Board shall have

                                       8
<PAGE>

determined, in its reasonable judgment, that the Company shall be required to
disclose any material corporate development which disclosure would have a
material effect on the Company in light of its current or future business plans
("Material Information"). Notwithstanding the foregoing to the contrary, (i) the
total number of days in which a Delay Period or Suspension Period is in effect
shall not, in the aggregate, exceed 120 days during any consecutive 365-day
period (the "Suspension Limit") and (ii) a Suspension Period or Delay Period
shall not begin until 30 days after the completion of a Suspension Period or
Delay Period. The Purchaser agrees that, upon receipt of any written notice from
the Company of a Suspension Period, the Purchaser shall forthwith discontinue
disposition of shares during any Suspension Period through the Shelf
Registration until the Purchaser (i) is advised in writing by the Company that
the use of the applicable prospectus may be resumed, (ii) has received copies of
a supplemental or amended prospectus, if applicable, and/or (iii) has received
copies of any additional or supplemental filings which are incorporated or
deemed to be incorporated by reference in such prospectus. During any Delay
Period or Suspension Period, the Purchaser agrees to maintain in confidence and
not to disclose to any other person the fact of such Delay Period or Suspension
Period or any other information concerning it (including, without limitation,
the notice from the Company relating thereto) until such time as (A) such
information becomes a matter of public record (whether by virtue of its
inclusion in such registration statement or otherwise), or (B) the Purchaser
shall be required to so disclose such information pursuant to subpoena or order
of any court or other governmental agency or body having jurisdiction over the
matter (subject to the requirements of such order, and only after the Purchaser
shall have given the Company prompt prior written notice of such requirement).

      4.4. Registration Statement Form. A registration requested pursuant to
Section 4.1 shall be effected by the filing of a registration statement on Form
S-3 (or any successor form) or, if the Company is not eligible to use Form S-3,
another form agreed to by the Purchaser.

      4.5. Expenses. The Company shall pay, and shall be responsible for, all
Registration Expenses in connection with the registrations and offerings,
including underwritten offerings, that are effected pursuant to this Section
4.5; provided that the Purchaser shall pay (a) all Registration Expenses to the
extent required to be paid by the Purchaser under applicable law and (b) all
underwriting discounts and commissions and transfer taxes, if any, with respect
to Registrable Securities sold by the Purchaser.

      5. Incidental Registrations. Subject to the last sentence of this Section
5, if the Company at any time proposes to register any of its equity securities
under the Securities Act for sale to the public, whether for the account of the
Company or the account of any security holder of the Company (including, but not
limited to, a shelf registration statement on Form S-3 or any successor form,
but other than pursuant to a registration on Form S-4 or S-8 or any successor
form), then the Company shall give prompt written notice (but in no event less
than 10 days prior to the initial filing with respect thereto) to the Purchaser
regarding such proposed registration. Upon the written request of the Purchaser
made within 5 days after the receipt of any such notice (which request shall
specify the number of Registrable Securities intended to be

                                       9
<PAGE>

disposed of by the Purchaser and the intended method or methods of disposition
thereof), the Company shall use its commercially reasonable efforts to effect
the registration under the Securities Act of such Registrable Securities in
accordance with such intended method or methods of disposition; provided that:

            (a) the Company shall not include Registrable Securities in such
      proposed registration to the extent that the Board shall have determined,
      after consultation with the managing underwriter for such offering, that
      it would materially and adversely affect the offering price to include any
      Registrable Securities in such registration; provided that, in the event
      of any such determination, the Company shall give the Purchaser notice of
      such determination in lieu of the notice otherwise required by the first
      sentence of this Section 5;

            (b) if, at any time after giving written notice (pursuant to this
      Section 5) of its intention to register equity securities and prior to the
      effective date of the registration statement filed in connection with such
      registration, the Company shall determine for any reason not to register
      such equity securities, the Company may, at its election, give written
      notice of such determination to the Purchaser and, thereupon, shall not be
      obligated to register any Registrable Securities in connection with such
      registration (but shall nevertheless pay the Registration Expenses in
      connection therewith), without prejudice, however, to the rights of the
      Purchaser that a registration be effected under Section 4.1; and

            (c) if in connection with a registration pursuant to this Section 5,
      the managing underwriter of such registration (or, in the case of an
      offering that is not underwritten, a nationally recognized investment
      banking firm) shall advise the Company in writing (with a copy to the
      Purchaser) that the number of securities requested and otherwise proposed
      to be included in such registration exceeds the number which can be sold
      in such offering without materially and adversely affecting the offering
      price of the securities being sold in such registration, then in the case
      of any registration pursuant to this Section 5, the Company shall include
      in such registration only the number which the Company is so advised can
      be sold in such offering without such material adverse effect; provided
      that in such case it shall first include the securities, if any, being
      sold by the Company, and, second, the Registrable Securities of the
      Purchaser.

      The Company shall pay all Registration Expenses in connection with each
registration of Registrable Securities requested pursuant to this Section 5;
provided that the Purchaser shall pay (a) all Registration Expenses to the
extent required to be paid by the Purchaser under applicable law and (b) all
underwriting discounts and commissions and transfer taxes, if any, applicable to
the Registrable Securities sold in such offering. No registration effected under
this Section 5 shall relieve the Company from its obligation to effect any
registration under Section 4.1 or prejudice the rights of the Purchaser under
Section 4.1 or its ability to offer and sell shares under any Shelf Registration
Statement. Notwithstanding anything to the contrary in this Section 5,

                                       10
<PAGE>

during any Shelf Effectiveness Period, the provisions of this Section 5 shall
only apply in respect of registrations for underwritten offerings for which a
"road show" is conducted.

      6. Registration Procedures. Subject to the provisions of Section 4.1(a),
including the Company's obligation to file the Initial Automatic Shelf
Registration Statements and any Subsequent Automatic Shelf Registration
Statement and the timing thereof as provided in Section 4.1(a), if and whenever
the Company is required to effect the registration of any Registrable Securities
under the Securities Act pursuant to Section 4 or Section 5, the Company shall
promptly:

            (a) prepare, and as soon as practicable, but in any event within 30
      days thereafter, file with the Commission, a registration statement with
      respect to such Registrable Securities, make all required filings with the
      NASD and use its commercially reasonable efforts to cause such
      registration statement to become and remain effective as soon as
      practicable;

            (b) prepare and promptly file with the Commission such amendments
      and post-effective amendments and supplements to such registration
      statement and the prospectus used in connection therewith and such free
      writing prospectuses under Rule 433 under the Securities Act (each, a
      "Free Writing Prospectus") and Exchange Act reports as may be necessary to
      keep such registration statement effective for so long as is required to
      comply with the provisions of the Securities Act and to complete the
      disposition of all securities covered by such registration statement in
      accordance with the intended method or methods of disposition thereof, but
      (other than in the case of a Shelf Registration Statement) in no event for
      a period of more than 180 days after such registration statement becomes
      effective (subject to Section 4.1(b));

            (c) furnish copies of all documents proposed to be filed with the
      Commission in connection with such registration (including any Free
      Writing Prospectus) to counsel selected by the Purchaser, and such
      documents shall be subject to the review of such counsel (which shall be
      reasonably prompt); provided that the Company shall not file any
      registration statement or any amendment or post-effective amendment or
      supplement to such registration statement or the prospectus or any
      supplement thereto or any Free Writing Prospectus or any Exchange Act
      reports (in each case relating to the disposition of Registrable
      Securities) used in connection therewith to which such counsel shall have
      reasonably objected on the grounds that such registration statement,
      prospectus, supplement, Free Writing Prospectus or Exchange Act report
      does not comply (explaining why) in all material respects with the
      requirements of the Securities Act or of the rules or regulations
      thereunder;

            (d) furnish to the Purchaser, without charge, such number of
      conformed copies of such registration statement and of each such amendment
      and supplement thereto (in each case including all exhibits and documents
      filed therewith) and such number of copies of the prospectus included in
      such

                                       11
<PAGE>

      registration statement (including each preliminary prospectus and any
      summary prospectus), any supplement, any other prospectus filed under Rule
      424 under the Securities Act and any Free Writing Prospectus, in
      conformity with the requirements of the Securities Act, and such other
      documents, as the Purchaser may reasonably request in order to facilitate
      the disposition of the Registrable Securities owned by the Purchaser in
      accordance with the intended method or methods of disposition thereof;

            (e) for a reasonable period prior to the filing of such registration
      statement, and throughout the period specified in Sections 3 and 5 hereof,
      make available for inspection by (A) the Purchaser, (B) the underwriters
      (which term, for purposes of this Agreement, shall include a person deemed
      to be an underwriter within the meaning of Section 2(a)(11) of the
      Securities Act), if any, thereof, (C) the sales or placement agent, if
      any, therefor, (D) counsel for such underwriters or agent, and (E) counsel
      for the Purchaser such financial and other information and books and
      records of the Company and its Subsidiaries, and cause the officers,
      employees, counsel and independent certified public accountants of the
      Company and its Subsidiaries to respond to such inquiries, as shall be
      reasonably necessary, in the judgment of the respective counsel referred
      to in such Section, to conduct a reasonable investigation within the
      meaning of Section 11 of the Securities Act; provided, however, that each
      such party shall be required to maintain in confidence and not to disclose
      to any other person any information or records provided by the Company
      until such time as (A) such information becomes a matter of public record
      (whether by virtue of its inclusion in such registration statement or
      otherwise), or (B) such person shall be required so to disclose such
      information pursuant to the subpoena or order of any court or other
      governmental agency or body having jurisdiction over the matter (subject
      to the requirements of such order, and only after such person shall have
      given the Company prompt prior written notice of such requirement);

            (f) use its commercially reasonable efforts to register or qualify
      such Registrable Securities covered by such registration statement under
      the securities or blue sky laws of such jurisdictions as the Purchaser
      shall reasonably request, and do any and all other acts and things which
      may be necessary or advisable to enable the Purchaser to consummate the
      disposition of such Registrable Securities in such jurisdictions in
      accordance with the intended method or methods of disposition thereof;
      provided that the Company shall not for any such purpose be required to
      qualify generally to do business as a foreign corporation in any
      jurisdiction wherein it is not so qualified, subject itself to taxation in
      any jurisdiction wherein it is not so subject, or take any action which
      would subject it to general service of process in any jurisdiction wherein
      it is not so subject;

            (g) use its commercially reasonable efforts to cause all Registrable
      Securities covered by such registration statement to be registered with or
      approved by such other governmental agencies, authorities or
      self-regulatory bodies as may be necessary by virtue of the business and
      operations of the

                                       12
<PAGE>

      Company to enable the Purchaser to consummate the disposition of such
      Registrable Securities in accordance with the intended method or methods
      of disposition thereof;

            (h) in any underwritten offering, including any Underwritten
      Take-Down Transaction, furnish to the Purchaser:

                  (i) an opinion of counsel for the Company experienced in
            securities law matters, addressed to the Purchaser or its designated
            affiliates and dated the date of the closing of such underwritten
            offering, and

                  (ii) a "comfort" letter (unless the registration is pursuant
            to Section 5 and such a letter is not otherwise being furnished to
            the Company), addressed to the Purchaser or its designated
            affiliates and dated the date of the underwriting agreement for such
            underwritten offering, signed by the independent public accountants
            who have issued an audit report on the Company's financial
            statements included in the registration statement,

      covering such matters as are customarily covered in opinions of counsel
      and in accountants' letters delivered to the underwriters in underwritten
      public offerings of securities and such other matters as the Purchaser may
      reasonably request;

            (i) (i) promptly upon discovery by the Company of any misstatement
      or omission notify the Purchaser at any time when a prospectus relating
      thereto is required to be delivered under the Securities Act of the
      happening of any event or existence of any fact as a result of which the
      prospectus (including any information incorporated by reference therein)
      included in such registration statement, as then in effect, includes an
      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 in light of the circumstances then existing, and (ii)
      promptly upon such discovery (except to the extent the Company delivers a
      Material Event Notice, in which case such period may be up to 60 days but
      shall end upon public disclosure of the material transaction which
      necessitated such Material Event Notice), prepare and furnish to the
      Purchaser a reasonable number of copies of a supplement to or an amendment
      of such prospectus as may be necessary so that, as thereafter delivered to
      the purchasers of such securities, such prospectus shall not 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 in light of the circumstances then existing; provided that,
      notwithstanding anything to the contrary herein, the Company shall not be
      permitted to exercise its right to deliver a Material Event Notice more
      than twice during any 365 day period;

                                       13
<PAGE>

            (j) if requested by any managing underwriter or underwriters, any
      placement or sales agent or the Purchaser, promptly incorporate in a
      prospectus supplement or post-effective amendment such information as is
      required by the applicable rules and regulations of the Commission that
      such managing underwriter or underwriters, such agent or the Purchaser
      specifies should be included therein relating to the terms of the sale of
      such Registrable Securities, including, without limitation, information
      with respect to the number of Registrable Securities being sold by the
      Purchaser, or agent or to any underwriters, the name and description of
      the Purchaser, agent or underwriter, the offering price of such
      Registrable Securities and any discount, commission or other compensation
      payable in respect thereof, the purchase price being paid therefor by such
      underwriters and with respect to any other terms of the offering of the
      Registrable Securities to be sold by the Purchaser or agent or to such
      underwriters; and make all required filings of such prospectus supplement
      or post-effective amendment promptly after notification of the matters to
      be incorporated in such prospectus supplement or post-effective amendment;

            (k) otherwise comply with all applicable rules and regulations of
      the Commission, and make available to its security holders, as soon as
      reasonably practicable an earnings statement of the Company (in form
      complying with the provisions of Rule 158 under the Securities Act)
      covering the period of at least 12 months, but not more than 18 months,
      beginning with the first month after the effective date of such
      registration statement;

            (l) notify the Purchaser (i) when the prospectus, any prospectus
      supplement, any post-effective amendment or any Free Writing Prospectus
      has been filed and, with respect to such registration statement or any
      post-effective amendment, when the same has become effective, (ii) of the
      receipt by the Company of any comments from the Commission or of any
      request by the Commission for amendments or supplements to such
      registration statement or to amend or to supplement such prospectus or for
      additional information, (iii) of the issuance by the Commission of any
      stop order suspending the effectiveness of such registration statement or
      the initiation of any proceedings for that purpose and (iv) of the
      suspension of the qualification of such securities for offering or sale in
      any jurisdiction, or of the institution of any proceedings for any of such
      purposes;

            (m) use its commercially reasonable efforts to obtain the withdrawal
      of any order suspending the effectiveness of such registration statement
      or any post-effective amendment thereto or the lifting of any suspension
      of the qualification (or exemption from qualification) of any Registrable
      Securities for sale in any jurisdiction in which they have been qualified
      for sale, in each such case at the earliest practicable date;

            (n) use its commercially reasonable efforts (i) to list such
      Registrable Securities on any securities exchange on which the equity
      securities of the Company are then listed and (ii) to provide an
      independent transfer agent

                                       14
<PAGE>

      and registrar for such Registrable Securities not later than the effective
      date of such registration statement and to instruct such transfer agent
      (A) to release any stop transfer order with respect to the certificates
      with respect to the Registrable Securities being sold and (B) to furnish
      certificates without restrictive legends representing ownership of the
      shares being sold, in such denominations requested by the Purchaser or the
      lead underwriter;

            (o) enter into such agreements and take such other actions as the
      Purchaser or the underwriters reasonably request in order to expedite or
      facilitate the disposition of such Registrable Securities, including,
      without limitation, (x) in the case of a request for an Underwritten
      Take-Down Transaction or (y) in the case of a request pursuant to Section
      4.1(b) that is for an underwritten offering, preparing for, and
      participating in "road shows," and all such other customary selling
      efforts as the Purchaser or the underwriters reasonably request in order
      to expedite or facilitate such disposition; provided that, notwithstanding
      anything to the contrary herein, the total number of "road shows" the
      Company shall be required to participate in pursuant to this Agreement
      shall not exceed two;

            (p) furnish to the Purchaser such information and assistance as the
      Purchaser may reasonably request in connection with any "due diligence"
      effort which the Purchaser deems appropriate;

            (q) cooperate with the Purchaser and each underwriter and their
      respective counsel in connection with any filings required to be made with
      the NASD, the Nasdaq Global Market, or any other securities exchange on
      which such Registrable Securities are traded or will be traded;

            (r) cooperate with the Purchaser and the managing underwriters, if
      any, to facilitate the timely preparation and delivery of any certificates
      representing Registrable Securities to be sold, which certificates shall
      be printed, lithographed or engraved, or produced by any combination of
      such methods; and, in the case of an underwritten offering, enable such
      Registrable Securities to be in such denominations and registered in such
      names as the managing underwriters may request at least two business days
      prior to any sale of the Registrable Securities;

            (s) cause its officers and employees to participate in, and to
      otherwise facilitate and cooperate with the preparation of the
      registration statement and prospectus and any amendments or supplements
      thereto (including participating in meetings, drafting sessions and due
      diligence sessions) taking into account the Company's business needs; and

            (t) use its commercially reasonable efforts to take all other steps
      necessary to effect the registration of the Registrable Securities as
      contemplated hereby.

                                       15
<PAGE>

      As a condition to its registration of Registrable Securities, the Company
may require the Purchaser to execute powers-of-attorney, custody arrangements
and other customary agreements appropriate to facilitate the offering and to
furnish to the Company such information regarding the Purchaser, its ownership
of Registrable Securities and the disposition of such Registrable Securities as
the Company may from time to time reasonably request in writing and as shall be
required by law in connection therewith. The Purchaser agrees to furnish
promptly to the Company all information required to be disclosed in order to
make the information previously furnished to the Company by the Purchaser not
materially misleading.

      The Company agrees not to file or make any amendment to any registration
statement with respect to any Registrable Securities, or any amendment of or
supplement to the prospectus or any Free Writing Prospectus used in connection
therewith, which refers to the Purchaser, or otherwise identifies the Purchaser
as the holder of any Registrable Securities, without the consent of the
Purchaser, such consent not to be unreasonably withheld or delayed, unless such
disclosure is required by law, in which case the Company shall provide written
notice to the Purchaser no less than five days prior to the filing of such
amendment to any registration statement or amendment of or supplement to the
prospectus or any Free Writing Prospectus.

      The Purchaser agrees that upon receipt of any notice from the Company of
the happening of any event of the kind described in Section 6(i), the Purchaser
shall promptly discontinue its disposition of Registrable Securities pursuant to
the registration statement covering Registrable Securities until the Purchaser's
receipt of the copies of the supplemented or amended prospectus contemplated by
Section 6(i). If so directed by the Company, the Purchaser shall deliver to the
Company (at the Company's expense) all copies, other than permanent file copies,
in the Purchaser's possession of the prospectus covering such Registrable
Securities at the time of receipt of such notice. In the event that the Company
shall give any such notice, the period mentioned in Section 5(b) shall be
extended by the number of days during the period from and including the date of
the giving of such notice to and including the date when the Purchaser shall
have received the copies of the supplemented or amended prospectus contemplated
by Section 6(i).

      7. Underwritten Offerings.

      7.1. Underwriting Agreement. If requested by the underwriters for any
underwritten offering (including any Underwritten Take-Down Transaction)
pursuant to a registration requested under Section 4.1 or 5, the Company shall
enter into an underwriting agreement with the underwriters for such offering,
such agreement to be reasonably satisfactory in substance and form to the
underwriters and to the Purchaser. Any such underwriting agreement shall contain
such representations and warranties by the Company and such other terms and
provisions as are customarily contained in agreements of this type, including,
without limitation, indemnities to the effect and to the extent provided in
Section 11. The Purchaser shall not be required by any underwriting agreement to
make any representations or warranties to or agreements with the Company or the
underwriters other than representations, warranties or

                                       16
<PAGE>

agreements regarding the Purchaser, the ownership of the Purchaser's Registrable
Securities and the Purchaser's intended method or methods of disposition and any
other representation required by law or to furnish any indemnity to any Person
which is broader than the indemnity furnished by the Purchaser pursuant to
Section 11.2.

      7.2. Selection of Underwriters. If the Company at any time proposes to
register any of its securities under the Securities Act for sale for its own
account pursuant to an underwritten offering, the Company shall have the right
to select the managing underwriter (which shall be of nationally recognized
standing) to administer the offering. Notwithstanding the foregoing sentence,
whenever a registration requested pursuant to Section 4.1 is for an underwritten
offering (including any Underwritten Take-Down Transaction), the Purchaser shall
have the right to select the managing underwriter (which shall be of nationally
recognized standing and reasonably acceptable to the Company) to administer the
offering.

      8. Holdback Agreements.

      (a) If and whenever (i) the Company proposes to register in an
underwritten offering any of its equity securities for its own account under the
Securities Act (other than pursuant to a registration on Form S-4 or S-8 or any
successor form) or (ii) the Purchaser requests to sell Registrable Securities in
an underwritten offering pursuant to Section 4.1 (including an Underwritten
Take-Down Transaction) or Section 5, the Purchaser agrees not to effect any
public offer, sale or distribution, including any sale pursuant to Rule 144
under the Securities Act, or to request registration under Section 4.1 of any
Registrable Securities within thirty days prior to the reasonably expected
effective date of the contemplated registration statement ("Expected Trigger
Date") and during the period beginning on the effective date of the registration
statement relating to such registration (the "Trigger Date") and until 90 days
(or such shorter period as the managing underwriter for any underwritten
offering may agree) after the Trigger Date, except as part of such registration;
provided that, with respect to any Underwritten Take-Down Transaction, the
Expected Trigger Date and the Trigger Date shall be deemed to be the reasonably
expected date of pricing and the date of pricing of such Underwritten Take-Down
Transaction, respectively. If requested by such managing underwriter, the
Purchaser agrees to execute an agreement to such effect with the Company and
consistent with such managing underwriter's customary form of holdback
agreement.

      (b) If and whenever the Purchaser requests to sell Registrable Securities
in an underwritten offering pursuant to Section 4.1 (including an Underwritten
Take-Down Transaction) or Section 5, the Company agrees not to effect any public
offer, sale or distribution of its equity securities or securities convertible
into or exchangeable or exercisable for any of such securities within thirty
days prior to the Expected Trigger Date and during the period beginning on the
Trigger Date and until 90 days (or such shorter period as the managing
underwriter may agree) after the Trigger Date (except (i) as part of such
registration, (ii) pursuant to an employee equity compensation plan, or (iii)
pursuant to a registration on Form S-4 or S-8 or any successor form); provided
that, with respect to any Underwritten Take-Down

                                       17
<PAGE>

Transaction, the Expected Trigger Date and the Trigger Date shall be deemed to
be the reasonably expected date of pricing and date of pricing of such
Underwritten Take-Down Transaction, respectively. In addition, with respect to
any such underwritten offering, if, and to the extent requested by the managing
underwriter, the Company shall use its commercially reasonable efforts to cause
each holder (other than the Purchaser) of its equity securities or any
securities convertible into or exchangeable or exercisable for any of such
securities, whether outstanding on the date of this Agreement or issued at any
time after the date of this Agreement (other than any such securities acquired
in a public offering), to agree not to effect any such public sale or
distribution of such securities during such period, and to cause each such
holder to enter into an agreement to such effect with the Company and consistent
with such managing underwriter's customary form of holdback agreement.

      9. Preparation; Reasonable Investigation. In connection with the
preparation and filing of each registration statement registering Registrable
Securities under the Securities Act, the Company shall give counsel referred to
in clause (c) of Section 6 the opportunity to participate in the preparation of
such registration statement, each prospectus included therein or filed with the
Commission, and each amendment thereof or supplement thereto, to the extent that
the foregoing relate to the disposition of Registrable Securities, and shall
give such counsel access to the financial and other records, pertinent corporate
documents and properties of the Company and its subsidiaries and opportunities
to discuss the business of the Company with its officers and the independent
public accountants who have issued audit reports on its financial statements in
each case as shall be reasonably requested by such counsel in connection with
such registration statement.

      10. No Grant of Future Registration Rights. The Company shall not grant
any shelf, demand or incidental registration rights that are senior to the
rights granted to the Purchaser hereunder to any other Person without the prior
written consent of the Purchaser.

      11. Indemnification.

      11.1. Indemnification by the Company. In the event of any registration of
any Registrable Securities pursuant to this Agreement, the Company shall
indemnify, defend and hold harmless (a) the Purchaser, (b) the Purchaser's
directors, members, stockholders, officers, partners, employees, agents and
Affiliates, (c) each Person who participates as an underwriter in the offering
or sale of such securities and (d) each Person, if any, who controls (within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act)
any of the foregoing ("Controlling Persons") against any and all losses, claims,
damages or liabilities (or actions or proceedings in respect thereof), jointly
or severally, directly or indirectly, based upon or arising out of (i) any
untrue statement or alleged untrue statement of a material fact contained in any
registration statement under which such Registrable Securities were registered
under the Securities Act, any preliminary prospectus or prospectus supplement,
final prospectus or prospectus supplement, summary prospectus or Free Writing
Prospectus contained therein or used in connection with the offering of
securities covered thereby,

                                       18
<PAGE>

or any amendment or supplement thereto, or (ii) any omission or alleged omission
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading; and the Company shall reimburse each such
indemnified party for any legal or any other expenses reasonably incurred by
them in connection with enforcing its rights hereunder or under the underwriting
agreement entered into in connection with such offering or investigating,
preparing, pursuing or defending any such loss, claim, damage, liability, action
or proceeding, except insofar as any such loss, claim, damage, liability,
action, proceeding or expense arises out of or is based upon an untrue statement
of a material fact or omission of a material fact made in such registration
statement, any such preliminary prospectus or prospectus supplement, final
prospectus or prospectus supplement, summary prospectus, or Free Writing
Prospectus in reliance upon and in conformity with information furnished to the
Company by such Person or any of its Controlling Persons expressly for use in
the preparation thereof in accordance with the second sentence of Section 11.2.
Such indemnity shall remain in full force and effect, regardless of any
investigation made by such indemnified party and shall survive the transfer of
such Registrable Securities by the Purchaser. If the Company is entitled to, and
does, assume the defense of the related action or proceedings provided herein,
then the indemnity agreement contained in this Section 11.1 shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability, action or
proceeding if such settlement is effected without the consent of the Company
(which consent shall not be unreasonably withheld or delayed).

      11.2. Indemnification by the Purchaser. In the event of the registration
of any Registrable Securities pursuant to Section 4.1 (or any Underwritten
Take-Down Transaction) or Section 4, the Purchaser shall indemnify, defend and
hold harmless, in the same manner and to the same extent as set forth in Section
11.1, the Company, its directors, officers, employees, agents and each person,
if any, who controls (within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act) the Company, with respect to any statement of a
material fact or alleged statement of a material fact in or omission of a
material fact or alleged omission from such registration statement, any
preliminary prospectus or prospectus supplement, final prospectus or prospectus
supplement or summary prospectus or Free Writing Prospectus contained therein,
or any amendment or supplement thereto, but only to the extent such statement or
alleged statement or such omission or alleged omission was made in reliance upon
and in conformity with information furnished to the Company by the Purchaser
expressly for use in the preparation of such registration statement, preliminary
prospectus or prospectus supplement, final prospectus or prospectus supplement,
summary prospectus or Free Writing Prospectus. The Company and the Purchaser
hereby acknowledge and agree that, unless otherwise expressly agreed to in
writing by the Purchaser, the only information furnished or to be furnished to
the Company for use in any registration statement or prospectus relating to the
Registrable Securities or in any amendment, supplement or preliminary materials
associated therewith are statements specifically relating to (a) the beneficial
ownership of shares of Common Stock by the Purchaser and its Affiliates and (b)
the name and address of the Purchaser. If any additional information about the
Purchaser or the plan of distribution (other than for an underwritten offering)
is required by law to be disclosed in any such document, then the Purchaser
shall not unreasonably withhold its agreement referred to in the

                                       19
<PAGE>

immediately preceding sentence of this Section 11.2. Such indemnity shall remain
in full force and effect, regardless of any investigation made by or on behalf
of the Company or any such director, officer or controlling person and shall
survive the transfer of such Registrable Securities by the Purchaser. The
indemnity agreement contained in this Section 11.2 shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability, action or
proceeding if such settlement is effected without the consent of the Purchaser
(which consent shall not be unreasonably withheld or delayed). The indemnity
provided by the Purchaser under this Section 11.2 shall be limited in amount to
the net amount of proceeds (i.e., net of expenses, underwriting discounts and
commissions) actually received by the Purchaser from the sale of Registrable
Securities pursuant to such registration statement.

      11.3. Notices of Claims, etc. Promptly after receipt by an indemnified
party of notice of the commencement of any action or proceeding involving a
claim referred to in the preceding paragraphs of this Section 11, such
indemnified party shall, if a claim in respect thereof is to be made against an
indemnifying party, give written notice to the indemnifying party of the
commencement of such action or proceeding; provided that the failure of any
indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under the preceding paragraphs of this
Section 11, except to the extent that the indemnifying party is materially
prejudiced by such failure to give notice. In case any such action is brought
against an indemnified party, the indemnifying party shall be entitled to
participate therein and to assume the defense thereof, jointly with any other
indemnifying party similarly notified, to the extent that it may wish, with
counsel reasonably satisfactory to such indemnified party, and after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party will not be liable to such
indemnified party for any legal or other expenses subsequently incurred by the
latter in connection with the defense thereof except for the reasonable fees and
expenses of any counsel retained by such indemnified party to monitor such
action or proceeding. Notwithstanding the foregoing, if such indemnified party
reasonably determines, based upon advice of independent counsel, that a conflict
of interest may exist between the indemnified party and the indemnifying party
with respect to such action and that it is advisable for such indemnified party
to be represented by separate counsel, such indemnified party may retain other
counsel, reasonably satisfactory to the indemnifying party, to represent such
indemnified party, and the indemnifying party shall pay all reasonable fees and
expenses of such counsel. No indemnifying party, in the defense of any such
claim or litigation, shall, except with the consent of such indemnified party,
which consent shall not be unreasonably withheld, consent to entry of any
judgment or enter into any settlement unless such judgment, compromise or
settlement (i) includes as an unconditional term thereof the giving by the
claimant or plaintiff to such indemnified party of a release from all liability
in respect of such claim or litigation, (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act, by or on behalf of
any indemnified party and (iii) does not require any action other than the
payment of money by the indemnifying party.

      11.4. Other Indemnification. Indemnification similar to that specified in
the preceding paragraphs of this Section 11 (with appropriate modifications)
shall be given

                                       20
<PAGE>

by the Company and the Purchaser with respect to any required registration
(other than under the Securities Act) or other qualification of such Registrable
Securities under any federal or state law or regulation of any governmental
authority.

      11.5. Indemnification Payments. Any indemnification required to be made by
an indemnifying party pursuant to this Section 11 shall be made by periodic
payments to the indemnified party during the course of the action or proceeding,
as and when bills are received by such indemnifying party with respect to an
indemnifiable loss, claim, damage, liability or expense incurred by such
indemnified party.

      11.6. Other Remedies. If for any reason any indemnification specified in
the preceding paragraphs of this Section 11 is unavailable, or is insufficient
to hold harmless an indemnified party, other than by reason of the exceptions
provided therein, then the indemnifying party shall contribute to the amount
paid or payable by the indemnified party as a result of such losses, claims,
damages, liabilities, actions, proceedings or expenses in such proportion as is
appropriate to reflect the relative faults of the indemnifying party on the one
hand and the indemnified party on the other and the statements or omissions or
alleged statements or omissions which resulted in such loss, claim, damage,
liability, action, proceeding or expense, as well as any other relevant
equitable considerations. The relative fault of the indemnifying party and of
the indemnified party shall be determined by reference to, among other things,
whether the 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 statements or omissions.
The parties hereto agree that it would not be just and equitable if
contributions pursuant to this Section 11.6 were to be determined by pro rata
allocation or by any other method of allocation which does not take into account
the equitable considerations referred to in the preceding sentence of this
Section 11.6. 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. Notwithstanding the other provisions of this Section 11, in
respect of any claim for indemnification pursuant to this Section 11, no
indemnifying party (other than the Company) shall be required to contribute
pursuant to this Section 11.6 any amount in excess of (a) the net proceeds
(i.e., net of expenses, underwriting discounts and commissions) received and
retained by such indemnifying party from the sale of its Registrable Securities
covered by the applicable registration statement, preliminary prospectus or
prospectus supplement, final prospectus or prospectus supplement, summary
prospectus or Free Writing Prospectus, filed pursuant hereto, minus (b) any
amounts previously paid by such indemnifying party pursuant to this Section 11
in respect of such claim. No party shall be liable for contribution under this
Section 11.6 except to the extent and under such circumstances as such party
would have been liable for indemnification under this Section 11 if such
indemnification were enforceable under applicable law.

      13. Miscellaneous.

      13.1. Rule 144, etc. The Company shall file the reports required to be
filed by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the Commission thereunder, and shall take such further
action as the Purchaser may reasonably request, all to the extent required from
time to time to enable the Purchaser to sell Registrable Securities without
registration under the Securities Act within the limitation of the exemptions
provided by (a) Rule 144 under the Securities Act, as such rule may be amended
from time to time, or (b) any successor rule or regulation hereafter adopted by
the Commission. Upon the request of the Purchaser, the Company shall deliver to
the Purchaser a written statement as to whether it has complied with such
requirements.

      13.2. Successors, Assigns and Transferees. This Agreement shall be binding
upon and inure to the benefit of and enforceable by the parties hereto and their

                                       26

respective permitted successors and assigns under this Section 13.2. The
provisions of this Agreement which are for the benefit of the Purchaser shall be
for the benefit of and enforceable by any transferee of no less than 1,000,000
shares of such Registrable Securities; provided that (i) such transferee
acquires such Registrable Securities pursuant to an express assignment from the
transferor, and (ii) such transferee executes a joinder agreement agreeing to be
bound by all of the transferor's obligations hereunder, copies of which shall

a stock split, reverse stock split, recapitalization or combination with respect
to any Registrable Securities in connection with any registration of any
Registrable Securities hereunder, or otherwise, if (i) the managing underwriter
shall advise the Company in writing (or, in connection with an offering that is
not underwritten, if an investment banker shall advise the Company in writing)
that in its opinion such a stock split, reverse stock split, recapitalization or
combination would facilitate or increase the likelihood of success of the
offering, and (ii) such stock split, reverse stock split, recapitalization or
combination does not impact the ownership percentage of the Purchaser in the
Company.

      13.4. Amendment and Modification.

      (a) This Agreement may be amended, waived, modified or supplemented by a
written instrument executed and delivered by the Company and the Purchaser. The
waiver by any party hereto of a breach of any provision of this Agreement shall
not operate or be construed as a further or continuing waiver of such breach or
as a waiver of any other or subsequent breach, except as otherwise explicitly
provided for in such waiver. Except as otherwise expressly provided herein, no
failure on the part of any party to exercise, and no delay in exercising, any
right, power or remedy hereunder, or otherwise available in respect hereof at
law or in equity, shall operate as a waiver thereof, nor shall any single or
partial exercise of such right, power or remedy by such party preclude any other
or further exercise thereof or the exercise of any other right, power or remedy.

      (b) Notwithstanding anything to the contrary herein, any actions to be
taken, or any rights to be exercised by the Purchaser hereunder (including, for
the avoidance of doubt, the execution and delivery of any amendments, waivers,
modifications or supplements of this Agreement pursuant to this Section 13.4),
shall be effective if taken or exercised by Persons owning a majority in
interest of the aggregate number of Registrable Securities, and the Company
shall be entitled to rely on the power and authority of such majority in
interest to take such actions and to exercise such rights.
