 ARTICLE III.  REGISTRATION RIGHTS
 -----------   -------------------

     The Company's obligation to register shares of Restricted Stock under this

terminate.

      Section 3.1  Piggyback Registration Rights.  If at any time or times
      -----------  -----------------------------
after the date which is three months after the date hereof, the Company shall
determine to register any shares of its Common Stock or securities convertible

                                       3
<PAGE>

Common Stock under the Securities Act (whether in connection with a public
offering of securities by the Company (a "primary offering"), a public offering
of securities by stockholders (a "secondary offering"), or both, but not in
connection with a registration effected solely to implement an employee benefit
plan or a transaction to which Rule 145 or any other similar rule of the
Commission under the Securities Act is applicable, the Company will promptly
give written notice thereof to the Holders. In connection with any such
registration, if within thirty (30) days after their receipt of such notice (or
10 days in the case of a proposed registration on Form S-3) any Holder requests
in writing the inclusion in such registration of some or all of the Registrable
Shares (as hereinafter defined) owned by such Holder, the Company will use its
best efforts to effect the registration under the Securities Act of all
Registrable Shares which such Seller or Holder so requests; provided, however,
                                                            --------  -------
that in the case of an underwritten public offering, if the underwriter
determines that a limitation on the number of shares to be underwritten is
required, the underwriter may limit the number of Registrable Shares and other
Common Stock for which the Company has granted registration rights to be
included in the registration and underwriting to not less in the aggregate than
thirty percent (30%) of the securities included therein (based on aggregate
market values). The Company shall advise each Holder promptly after such
determination by the underwriter, and the number of Registrable Shares that may
be included in the registration and underwriting shall be allocated among all
Investors, Founders, and the Holders requesting registration in proportion, as
nearly as practicable, to the respective holdings by such Persons of Registrable
Shares and other Common Stock for which the Company has granted registration
rights. All expenses of the registration and offering shall be borne by the
Company, except that the Holders shall bear underwriting and selling commissions
and transfer taxes attributable to the sale of their Registrable Shares.

      Section 3.2  Registrable Shares.  For the purposes of this Article III,
      -----------  ------------------
the term "Registrable Shares" shall mean any shares of Restricted Stock held by
a Holder including any shares issued by way of a stock dividend or stock split
or in connection with a combination of shares, recapitalization, merger,
consolidation or other reorganization; provided, that any Restricted Stock that
                                       --------
is sold in a registered sale pursuant to an effective registration statement
under the Securities Act or pursuant to Rule 144 thereunder, or that may then be
sold pursuant to Rule 144 under the Securities Act, shall not be deemed
Registrable Shares.

      Section 3.2  Further Obligations of the Company.  Whenever, under the
      -----------  ----------------------------------
provisions of Section 3.1 of this Agreement, the Company is required to register
any Registrable Shares, it agrees that it shall also do the following:

               (a) Use its best efforts to diligently prepare and file with the
     Commission a registration statement and such amendments, post-effective
     amendments and supplements to said registration statement and the
     prospectus used in connection therewith as may be necessary to keep said
     registration statement effective as contemplated herein and to comply with
     the provisions of the Securities Act with respect to the sale of securities
     covered by said registration statement for the period necessary to complete
     the proposed public offering as provided herein;

                                       4
<PAGE>

               (b) Furnish to each selling Holder such copies of each
     preliminary and final prospectus, registration statement and prospectus
     supplements thereto and such other documents as such Holders may reasonably
     request to facilitate the public offering of its Registrable Shares;

               (c) Enter into any reasonable underwriting agreement required by
     the proposed underwriter for the selling Holders if any; provided, however,
     that no Holder shall be required to make any representations or warranties
     other than with respect to its title to the Registrable Shares and any
     written information provided by such Holder to the Company specifically for
     use in the Registration Statement, and if the underwriter requires that
     representations or warranties be made and that indemnification be provided,
     the Company shall make all such representations and warranties and provide
     all such indemnities, including, without limitation, in respect of the
     Company's business, operations and financial information and the
     disclosures relating thereto in the prospectus;

               (d) Use its best efforts to register or qualify the securities
     covered by said registration statement under the securities or "blue-sky"
     laws of such jurisdictions as any selling Holders may reasonably request,
     provided that the Company shall not be required to register or qualify the
     securities in any jurisdictions which require it to qualify to do business
     or subject itself to general service of process therein;

               (e) Immediately notify each selling Holder at any time when a
     prospectus relating to his or her Registrable Shares is required to be
     delivered under the Securities Act, of the happening of any event as a
     result of which such prospectus contains an untrue statement of a material
     fact or omits any material fact necessary to make the statements therein
     not misleading, and, at the request of any such selling Holder, prepare a
     supplement or amendment to such prospectus so that, as thereafter delivered
     to the purchasers of such Registrable Shares, such prospectus will not
     contain any untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein not misleading;

               (f) Cause all such Registrable Shares to be listed on or included
     in each securities exchange or quotation system on which similar securities
     issued by the Company are then listed;

               (g) Otherwise use its best efforts to comply with all applicable
     rules and regulations of the Commission and make generally available to its
     stockholders, in each case as soon as practicable, but not later than 30
     days after the close of the period covered thereby an earnings statement of
     the Company which will satisfy the provisions of Section 11(a) of the
     Securities Act;

                                       5
<PAGE>

               (h) Cooperate with each Holder and each underwriter participating
     in the disposition of Registrable Shares and their respective counsel in
     connection with any filings required to be made with the National
     Association of Securities Dealers, Inc.;

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

               (j) Appoint a transfer agent and registrar for all Registrable
     Shares covered by a Registration Statement not later than the effective
     date of such Registration Statement;

               (k) In connection with an underwritten offering, to the extent
     reasonably requested by the managing underwriter for the offering, to
     participate in and support customary efforts to sell the securities in the
     offering, including, without limitation, participating in "road shows"; and

               (l) Otherwise cooperate with the underwriter or underwriters, the
     Commission and other regulatory agencies and take all actions and execute
     and deliver or cause to be executed and delivered all documents necessary
     to effect the registration of any Registrable Shares under this Article
     III.

      Section 3.4  Indemnification; Contribution.
      -----------  -----------------------------

               (a) Incident to any registration statement referred to in this
     Article III, and subject to applicable law, the Company will indemnify and
     hold harmless each underwriter, and each Holder who offers or sells any
     such Registrable Shares in connection with such registration statement
     (including its partners (including partners of partners and stockholders of
     any such partners), and directors, officers, employees and agents of any of
     them (a "Selling Stockholder"), and each person who controls any of them
     within the meaning of Section 15 of the Securities Act or Section 20 of the
     Exchange Act (a "Controlling Person"), from and against any and all losses,
     claims, damages, expenses and liabilities, joint or several (including any
     investigation, legal and other expenses incurred in connection with, and
     any amount paid in settlement of, any action, suit or proceeding or any
     claim asserted), as the same are incurred to which they, or any of them,
     may become subject under the Securities Act, the Exchange Act or other
     federal or state statutory law or regulation, at common law or otherwise,
     insofar as such losses, claims, damages or liabilities arise out of or are
     based on (i) any untrue statement or alleged untrue statement of a material
     fact contained in such registration statement (including any related
     preliminary or definitive prospectus, or any amendment or supplement to
     such registration statement or prospectus), (ii) any omission or alleged
     omission to state in such document a material fact required to be stated in
     it or necessary to make the statements in it not misleading, or (iii) any
     violation by the Company of the Securities Act, any state securities or
     "blue sky" laws

                                       6
<PAGE>

     or any rule or regulation thereunder in connection with such registration;
     provided, however, that the Company will not be liable to the extent that
     such loss, claim, damage, expense or liability arises from and is based on
     an untrue statement or omission or alleged untrue statement or omission
     made in reliance on and in conformity with information furnished in writing
     to the Company by such underwriter or Selling Stockholder expressly for use
     in such registration statement. With respect to such untrue statement or
     omission or alleged untrue statement or omission in the information
     furnished in writing to the Company by such Selling Stockholder expressly
     for use in such registration statement, such Selling Stockholder will
     indemnify and hold harmless each underwriter, the Company (including its
     directors, officers, employees and agents), and each other Selling
     Stockholder (including its partners (including partners of partners and
     stockholders of such partners) and directors, officers, employees and
     agents of any of them), and each person who controls any of them within the
     meaning of Section 15 of the Securities Act or Section 20 of the Exchange
     Act, from and against any and all losses, claims, damages, expenses and
     liabilities, joint or several, to which they, or any of them, may become
     subject under the Securities Act, the Exchange Act or other federal or
     state statutory law or regulation, at common law or otherwise to the same
     extent provided in the immediately preceding sentence. In no event,
     however, shall the liability of a Selling Stockholder for indemnification
     under this Section 3.4(a) in its capacity as such exceed the lesser of (i)
     that proportion of the total of such losses, claims, damages or liabilities
     indemnified against equal to the proportion of the total securities sold
     under such registration statement which is being sold by such Selling
     Stockholder or (ii) the proceeds received by such Selling Stockholder from
     its sale of Registrable Shares under such registration statement.

               (b) If the indemnification provided for in Section 3.4(a) above
     for any reason is held by a court of competent jurisdiction to be
     unavailable to an indemnified party in respect of any losses, claims,
     damages, expenses or liabilities referred to therein, then each
     indemnifying party under this Section 3.4, in lieu of indemnifying such
     indemnified party thereunder, shall contribute to the amount paid or
     payable by such indemnified party as a result of such losses, claims,
     damages, expenses or liabilities (i) in such proportion as is appropriate
     to reflect the relative benefits received by the Company, the other Selling
     Stockholders and the underwriters from the offering of the Registrable
     Shares or (ii) if the allocation provided by clause (i) above is not
     permitted by applicable law, in such proportion as is appropriate to
     reflect not only the relative benefits referred to in clause (i) above but
     also the relative fault of the Company, the other Selling Stockholders and
     the underwriters in connection with the statements or omissions which
     resulted in such losses, claims, damages, expenses or liabilities, as well
     as any other relevant equitable considerations.  The relative benefits
     received by the Company, the Selling Stockholders and the underwriters
     shall be deemed to be in the same respective proportions that the net
     proceeds from the offering (before deducting expenses) received by the
     Company and the Selling Stockholders and the underwriting discount received
     by the underwriters, in each case as set forth in the table on the cover
     page of the applicable prospectus, bear to the aggregate public

                                       7
<PAGE>

     offering price of the Registrable Shares. The relative fault of the
     Company, the Selling Stockholders and the underwriters shall be determined
     by reference to, among other things, whether the untrue or alleged untrue
     statement of a material fact or the omission or alleged omission to state a
     material fact relates to information supplied by the Company, the Selling
     Stockholders or the underwriters and the parties' relative intent,
     knowledge, access to information and opportunity to correct or prevent such
     statement or omission.

               The Company, the Selling Stockholders, and the underwriters agree
     that it would not be just and equitable if contribution pursuant to this
     Section 3.4(b) were determined by pro rata or per capita allocation or by
     any other method of allocation which does not take account of the equitable
     considerations referred to in the immediately preceding paragraph.  In no
     event, however, shall a Selling Stockholder be required to contribute any
     amount under this Section 3.4(b) in excess of the lesser of (i) that
     proportion of the total of such losses, claims, damages or liabilities
     indemnified against equal to the proportion of the total Registrable Shares
     sold under such registration statement which are being sold by such Selling
     Stockholder or (ii) the proceeds received by such Selling Stockholder from
     its sale of Registrable Shares under such registration statement.  No
     person found 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 found guilty of such fraudulent misrepresentation.

               (c) The amount paid by an indemnifying party or payable to an
     indemnified party as a result of the losses, claims, damages and
     liabilities referred to in this Section 3.4 shall be deemed to include,
     subject to the limitations set forth above, any legal or other expenses
     reasonably incurred by such indemnified party in connection with
     investigating or defending any such action or claim, payable as the same
     are incurred.  The indemnification and contribution provided for in this
     Section 3.4 will remain in full force and effect regardless of any
     investigation made by or on behalf of the indemnified parties or any
     officer, director, employee, agent or controlling person of the indemnified
     parties, and regardless of any transfer or sale of shares by any Holder or
     any termination of Holder's rights to registration hereunder.

      Section 3.5  Rule 144 Requirements.  The Company shall furnish to any
      -----------  ---------------------
holder of Registrable Shares upon request a written statement executed by the
Company as to the steps it has taken to comply with the current public
information requirement of Rule 144 or such successor rules. The Company shall
use its best efforts to comply with the current public information requirements
of Rule 144. In connection with a sale of Restricted Stock by a Holder pursuant
to Rule 144, assuming the Holders provide standard Rule 144 representation
letters, the Company agrees that the Holders shall not be required to pay for
any legal opinion required to effect such a transfer.

                                       8
<PAGE>

     If at any time the Company is not a reporting company under Section 13 or
15(d) of the Securities and Exchange Act of 1934 or has not complied with the
requirements for the exemption from registration under the Securities and
Exchange Act of 1934 set forth in Rule 12g3-2b under such Act, the Company shall
furnish to any Holder of Registrable Shares such financial or other information
as any such Holder or any person designated by such Holder may reasonably
determine to be required to permit such Holder to comply with the requirements
of Rule 144A promulgated under the Act in connection with the resale by it of
the Registrable Shares in any such case promptly after the same is requested.
