after the 180th day following the date on which any registration statement
pursuant to which the Company shall have initially registered (a) shares of
Common Stock, or (b) securities providing the holder thereof the right to
acquire shares of Common Stock, under the Securities Act for sale to the public
shall have been declared effective, the Company shall receive a Demand Notice,
the Company shall promptly give written notice of such proposed registration to
all other Stockholders and shall offer to include in such proposed registration
any Registrable Securities requested to be included in such proposed
registration by the Stockholders who shall respond in writing to the Company's
notice within 10 days after receipt by the Stockholders in question of such
notice (which response shall specify the number of Registrable Securities
proposed to be included in such registration). Subject to section 2.2, the
Company shall promptly use its best efforts to effect such registration under
the Securities Act of the Registrable Securities that the Company has been so
requested to register on such appropriate registration form of the Commission as
shall be selected by the Company.

     2.2 Limits on Demand Rights.

          (a) The Company shall not be obligated to file and cause to become
     effective (i) more than two registration statements pursuant to Investor
     Demand Notices; provided, however, that in addition thereto, the Investors
     may require the Company to file registration statements on Form S-3 from
     time to time, if the use of such Form is available to the Company; (ii)
     more than two registration statements pursuant to Founder Demand Notices;
     and (iii) any registration statement during the period beginning 30 days
     prior to the filing and ending 90 days following the effective date of a
     registration statement filed by the Company and relating to an underwritten
     offering in which a majority of the shares are being sold by the Company
     for its own account.

          (b) Unless the Company shall have delayed the commencement of a
     registration statement pursuant to section 2.2(a)(ii) above or section
     2.2(c) below, the Company may delay the filing or effectiveness of any
     registration statement for a period of up to 60 days after the date of
     delivery of the Demand Notice pursuant to this section 2 if at the time of
     such request the Company is engaged in a firm commitment underwritten
     public offering of Company Shares in which the Stockholders may include
     Registrable Securities pursuant to section 3,


                                       -3-

<PAGE>

     provided, however, that, in the event the Company exercises its rights
     under this section 2.2(b), the registration shall not be counted as a
     demand for registration by any Stockholder for purposes of section
     2.2(a)(i) hereof.

          (c) If, while a registration request is pending pursuant to this
     section 2, the Company has been advised by legal counsel (i) that the
     filing of a registration statement would require the disclosure of a
     material transaction or other factor that the Company reasonably determines
     in good faith would have a material adverse effect on the Company or (ii)
     the Company then is unable to comply with Commission requirements
     applicable to the requested registration, the Company shall not be required
     to effect a registration pursuant to this section 2 until the earlier of
     (A) the date upon which such material information is otherwise disclosed to
     the public or ceases to be material or the Company is able to so comply
     with applicable Commission requirements, as the case may be, and (B) 60
     days after the Company makes such good faith determination, provided that
     in the event the Company exercises its rights under this section 2.2(c),
     the registration shall not be counted as a demand for registration by any
     Stockholder for purposes of section 2.2(a)(i) hereof, and provided further
     that the Company may not exercise its right under this section 2.2(c) more
     than once in any 12-month period.

          (d) A requested registration under this section 2 may be rescinded by
     written notice to the Company by the Holder or Holders initiating such
     request. Such rescinded registration shall not count as a registration
     statement initiated pursuant to this section 2 for purposes of section 2.2
     above if such request is rescinded by such Holder or Holders not later than
     five business days prior to the filing of a registration statement with the
     Commission.

     2.3 Underwriter "Cutbacks" in Demand Registrations. With respect to any
registration pursuant to this section 2 that is being effected by one or more
underwriters such underwriters shall be designated by the Company and approved
by a majority in interest or the Holders selling Registrable Securities and
Other Securities (which approval shall not be unreasonably withheld), and the
Company may include in such registration any Other Securities; provided,
however, that, anything to the contrary in section 2.1 notwithstanding, if any
managing underwriter for the public offering contemplated by such registration
advises the Company in writing that, in such firm's good faith opinion, the
inclusion of all Registrable Securities and Other Securities proposed to be
included in such registration would adversely affect the offering and sale of
all such securities, then the number of Registrable Securities and Other
Securities proposed to be included in such registration shall be reduced pro
rata based upon the number of shares of Common Stock owned by each such Person
and its affiliates (or that each such Person and its affiliates have the right
to acquire) at the time of such registration.

     3. Piggyback Registration.

     3.1 Right to Include Registrable Securities.


          (a) Subject to section 3.1(b), if the Company at any time proposes to
     register any of its securities under the Securities Act (as defined below)
     by registration on Forms SB-2, S-1, S-2, S-3 (but not Forms S-4 or S-8) or
     any successor or similar form(s) (except registrations on such or similar
     forms for registration of securities in connection with (i) an employee
     benefit


                                       -4-

<PAGE>

     plan or dividend reinvestment plan or a merger, consolidation or other
     business combination, (ii) debt securities that are not convertible into
     Common Stock, or (iii) the Company's initial public offering), whether or
     not for sale for its own account, it shall, each such time, give written
     notice to the Holders of its intention to do so and of the Holders' rights
     under this section 3 at least 30 days prior to the filing of a registration
     statement with respect to such registration with the Commission. Upon the
     written request of any Holder made within 20 days after the receipt of that
     notice, which request shall specify the Registrable Securities intended to
     be registered and disposed of by such Holder, the Company shall, subject to
     the provisions hereof, use its best efforts to include in such registration
     statement all Registrable Securities that the Company has been so requested
     to register by such Holder.

          (b) If, at any time after giving written notice of its intention to
     register any 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 or to delay registration of such
     securities, the Company may, at its election, give written notice of such
     determination to each Holder and upon giving that notice (i) in the case of
     a determination not to register, the Company shall be relieved of its
     obligation to register any Registrable Securities in connection with such
     registration (but not from any obligation of the Company to pay the
     Registration Expenses (as defined below) in connection therewith), without
     prejudice; and (ii) in the case of a determination to delay registering,
     the Company shall be permitted to delay registering any Registrable
     Securities for the same period as the delay in registering such other
     securities.

          (c) The Company shall pay all Registration Expenses in connection with
     registration of Registrable Securities requested pursuant to this section
     3.1.

     3.2 Underwriter "Cutbacks" in Piggyback Registrations. Anything in section
3.1 to the contrary notwithstanding, with respect to any registration pursuant
to which shares are registered pursuant to this section 3 that is being effected
by one or more underwriters, such underwriters shall be designated by the
Company and approved by a majority in interest of the Holders selling
Registrable Securities and Other Securities (which approval shall not be
unreasonably withheld), and if any managing underwriter for the public offering
contemplated by such registration advises the Company in writing that, in such
firm's good faith opinion, the inclusion of all Registrable Securities and Other
Securities proposed to be included in such registration would adversely affect
the offering and sale of all such securities, then all securities proposed to be
sold by the Company for its own account shall be included in such registration
to the extent possible and the number of Registrable Securities and Other
Securities proposed to be included in such registration shall be reduced pro
rata based upon the number of shares of Common Stock owned by each such Person
(other than the Company) and its affiliates (or that each such Person and its
affiliates have the right to acquire) at the time of such registration.

     4. Registration Procedures. In connection with the registration of any
Registrable Securities under the Securities Act as provided in sections 2 and 3,
the Company shall as expeditiously as possible:

          (i) prepare and file with the Commission the requisite registration
     statement to effect such registration and thereafter use its best efforts
     to cause such


                                       -5-

<PAGE>

     registration statement to become and remain effective (subject to clause
     (ii) below); provided, however, that the Company may discontinue any
     registration of its securities that are not Registrable Securities at any
     time prior to the effective date of the registration statement relating
     thereto;

          (ii) prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective and to comply with the provisions of the Securities Act
     with respect to the disposition of all Registrable Securities covered by
     such registration statement for such period as shall be required for the
     disposition of all of such Registrable Securities; provided, however, that,
     the foregoing notwithstanding, the Company shall not be required under this
     item (ii) to maintain the effectiveness of any such registration statement
     for longer than 180 days, or such longer period beyond such 180 days (up to
     an aggregate of 270 days) as may be available without requiring the Company
     to file any financial statements as of a later date and for a later period
     than the financial statements that may have been required to maintain the
     effectiveness of the registration statement for the 180-day period;

          (iii) furnish to the Holders such number of conformed copies of such
     registration statement and of each such amendment and supplement thereto
     (in each case including all exhibits), such number of copies of the
     prospectus contained in such registration statement (including each
     preliminary prospectus and any summary prospectus) and any other prospectus
     filed under Rule 424 under the Securities Act, in conformity with the
     requirements of the Securities Act, and such other documents, as the
     Holders may reasonably request from time to time;

          (iv) use its best efforts (x) to register or qualify all Registrable
     Securities and other securities covered by such registration statement
     under such other securities or blue sky laws of such states of the United
     States of America where an exemption is not available and as the Holders
     shall reasonably request, (y) to keep such registration or qualification in
     effect for so long as such registration statement remains in effect, and
     (z) to take any other action that may reasonably be necessary or advisable
     to enable the Holders to consummate the disposition in such jurisdictions
     of the securities to be sold by the Holders, except 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 would not, but for the
     requirements of this paragraph (iv), be obligated to be so qualified or to
     consent to general service of process in any such jurisdiction;

          (v) use its best efforts to cause all Registrable Securities covered
     by such registration statement to be registered with or approved by such
     other federal or state governmental agencies or authorities as may be
     necessary in the opinion of counsel to the Company to consummate the
     disposition of such Registrable Securities in accordance with their
     intended method of disposition;

          (vi)furnish to the Holders' underwriters, if any, (x) an opinion of
     counsel for the Company, and (y) a "comfort" letter signed by the
     independent public accountants who have certified the Company's financial
     statements included or


                                       -6-

<PAGE>

     incorporated by reference in such registration statement, each covering
     substantially the same matters with respect to such registration statement
     (and the prospectus included therein) and, in the case of the accountant's
     comfort letter, with respect to events subsequent to the date of such
     financial statements, as are customarily covered in opinions of issuer's
     counsel and in accountant's comfort letters delivered to the underwriters
     in underwritten public offerings of securities (and dated the dates such
     opinions and comfort letters are customarily dated);

          (vii) immediately notify the Holders when a prospectus relating
     thereto is required to be delivered under the Securities Act, upon
     discovery that, or upon the happening of any event as a result of which,
     the prospectus 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 the light of the circumstances under
     which they were made, and at the request of the Holders promptly prepare
     and furnish to them 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 the light of the circumstances under which they
     were made;

          (viii) otherwise use its best efforts to 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 covering
     the period of at least 12 months, but not more than 18 months, beginning
     with the first full calendar month after the effective date of such
     registration statement, which earnings statement shall satisfy the
     provisions of section 11(a) of the Securities Act and Rule 158 promulgated
     thereunder, and promptly furnish the same to the Holders; and

          (ix) provide and cause to be maintained a transfer agent and registrar
     (which, in each case, may be the Company) for all Registrable Securities
     covered by such registration statement from and after a date not later than
     the effective date of such registration.

     The Company may require the Holders to furnish the Company such information
regarding the Holders and the distribution of the Holders' Registrable
Securities as the Company may from time to time reasonably request in writing,
based on its reasonable belief that such information is required to be disclosed
in the Registration Statement pursuant to the Securities Act and applicable
State securities laws.

     Upon receipt of any notice from the Company of the happening of an event of
the kind described in item (vii) of this section 4, the Holders shall forthwith
discontinue their disposition of Registrable Securities pursuant to the
registration statement relating to such Registrable Securities until the
Holders' receipt of the copies of the supplemented or amended prospectus
contemplated by item (vii) and, if so directed by the Company, the Holders shall
deliver to the Company all copies, other than permanent file copies, then in the
Holders'


                                       -7-

possession, of the prospectus relating to such Registrable Securities current at
the time of receipt of such notice.

underwriters, the Company shall, subject to the provisions of section 2 and
section 3 (including, without limitation, the provisions of sections 2.3 and
3.2), if requested by the Holders, arrange for such underwriters to include all
the Registrable Securities to be offered and sold by the Holders with and among
the securities of the Company to be distributed by such underwriters. The
Holders shall become a party to the underwriting agreement negotiated between
the Company and such underwriters and shall make all representations and
warranties to and shall enter into all agreements with the Company or the
underwriters as shall be reasonably requested of them including all
representations and warranties required by law, customarily given or reasonably
requested of selling shareholders by an underwriter in an underwritten public
offering.

     5.2 Holdback Agreements.

          (a) If the Company, in connection with an underwritten offering of
     securities for its own account, at any time shall register shares of Common
     Stock under the Securities Act for sale to the public (other than on Forms
     S-4 or S-8 or a shelf registration), the Holders shall not sell pursuant to
     an effective registration statement, publicly make any short sale of,
     publicly grant any option for the purchase of, or otherwise publicly
     dispose of any Shares (other than those Shares included in such
     registration pursuant to section 2 or section 3) without the prior written
     consent of the managing underwriter for a period required by the
     underwriters and designated by the Company, which period shall begin not
     more than thirty (30) days prior to the effectiveness of the registration
     statement pursuant to which such public offering shall be made and shall
     last not more than one hundred eighty (180) days after the effective date
     of such registration statement in the case of the Company's initial public
     offering, or ninety (90) days after the effective date of such registration
     statement in the case of any such other offering. The Company may legend
     and impose stop transfer instructions on any certificate evidencing
     Registrable Securities relating to the restrictions provided in this
     section 5.2.

          (b) During the 15-day period prior to the effective date of any
     registration statement of Registrable Securities pursuant to an
     underwritten public offering and during the 90-day period beginning on that
     effective date, the Company shall not (except as part of such registration)
     effect any public sale or distribution of any of its equity securities or
     of any security convertible into or exchangeable or exercisable for any
     equity security of the Company (other than in connection with any employee
     stock option or other benefit plan).

     5.3 Preparation; Reasonable Investigation. In connection with the
preparation and filing of each registration statement under the Securities Act
pursuant to this agreement, the Company shall give the Holders, their
underwriters, if any, and their respective counsel and accountants 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


                                       -8-

<PAGE>

supplement thereto, and give each of them such access to its books and records,
such opportunities to discuss the business of the Company with officers and the
independent public accountants who have certified its financial statements as
shall be necessary, in the opinion of the Holders' and such underwriters'
respective counsel, to conduct a reasonable investigation within the meaning of
the Securities Act.

     6. Indemnification.

     6.1 Indemnification by the Company. In the event of any registration
statement filed pursuant to section 2 or section 3, the Company shall, and
hereby does, indemnify and hold harmless each of the Holders and each of their
directors, officers, partners, agents, attorneys, representatives and affiliates
and each other individual, group, partnership, corporation, business trust,
joint stock company, trust, unincorporated association, joint venture or other
entity of whatever nature ("Person") who participates as an underwriter in the
offering or sale of such securities and each other Person, if any, who controls
any Holder or any such underwriter within the meaning of the Securities Act
(each of the foregoing, a "Holder Indemnitee"), insofar as losses, claims,
damages, or liabilities (or actions or proceedings, whether commenced or
threatened, in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of any material fact contained in any such
registration statement, any preliminary prospectus, final prospectus, or summary
prospectus contained therein, or any amendment or supplement thereto, or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein in light of the
circumstances in which they were made not misleading, and the Company shall
reimburse each Holder Indemnitee for any legal or any other fees, costs and
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, liability, action or proceeding; provided, that
the Company shall not be liable in any such case to the extent that any such
loss, claim, damage, liability (or action or proceeding in respect thereof) or
expense arises out of or is based upon an untrue statement or omission made in
reliance upon and in conformity with information furnished to the Company by or
on behalf of a Holder or such underwriter, as the case may be, for use in the
preparation thereof; and provided, further, that the Company shall not be liable
to any Holder Indemnitee in any such case to the extent that any such loss,
claim, damage, liability (or action or proceeding in respect thereof) or expense
arises out of such Person's failure to send or give a copy of the final
prospectus, as the same may be then supplemented or amended, to the Person
asserting an untrue statement or alleged untrue statement or omission or alleged
omission at or prior to the written confirmation of the sale of Registrable
Securities to such Person if such statement or omission was corrected in such
final prospectus so long as such final prospectus, and any amendments or
supplements thereto, have been furnished to such underwriter or any Holder, as
applicable.

     6.2 Indemnification by the Holders. If any Registrable Securities are
included in any registration statement, the Holders of such Registrable
Securities so registered shall, and hereby do, severally and not jointly,
indemnify and hold harmless (in the same manner and to the same extent as set
forth in section 6.1 above) the Company, and each director and officer of the
Company, and each other Person, if any, who controls the Company within the
meaning of the Securities Act, with respect to all losses, claims, damages,
expenses or liabilities ("Losses") to which the Company or such control person
becomes subject under the Securities Act, insofar as such Losses arise out of or
are based upon any untrue statement or alleged untrue statement of a


                                       -9-

<PAGE>

material fact contained in such registration statement, any preliminary
prospectus, final prospectus or summary prospectus contained therein, or any
amendment or supplement thereto, or an omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, if such statement or alleged statement or
omission or alleged omission was made in reliance upon and in conformity with
written information pertaining to such Holder and furnished to the Company by
such Holder for use in the preparation of such registration statement,
preliminary prospectus, final prospectus, summary prospectus, amendment or
supplement, provided, however, that no Holder shall have any liability under
this section 6.2 for any amount in excess of the net proceeds actually received
by such Holder from the sale of the Registrable Securities included in such
registration statement.

     6.3 Notice of Claims, Etc.

          (a) Promptly after receipt by an indemnified party of notice of the
     commencement of any action or proceeding involving a claim referred to in
     sections 6.1 or 6.2, such indemnified party will, if a claim in respect
     thereof is to be made against an indemnifying party, immediately give
     written notice to the latter of the commencement of such action; provided,
     however, that the failure of any indemnified party to give notice as
     provided herein shall not relieve the indemnifying party of its indemnity
     obligations, except to the extent that the indemnifying party is actually
     prejudiced by such failure to give notice. In case any such action is
     brought against an indemnified party, unless in the reasonable judgment of
     counsel for such indemnified party, a conflict of interest between such
     indemnified and indemnifying parties may exist in respect of such claim (in
     which case the indemnified party shall be entitled to retain separate
     counsel as provided below), the indemnifying party shall be entitled to
     participate in and to assume the defense thereof, jointly with any other
     indemnifying party similarly notified to the extent that it may wish and at
     any time, 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 shall
     not be liable to such indemnified party for any legal or other expenses
     subsequently incurred by the indemnified party in connection with the
     defense thereof other than reasonable costs related to the indemnified
     party's cooperation with the indemnifying party provided, however, that (i)
     if the indemnifying party fails to assume the defense of such claim after a
     reasonable time the indemnified party may retain counsel to defend such
     claim and the reasonable fees and expenses of such counsel shall be paid by
     the indemnifying party, (ii) the indemnified party may, at its own expense,
     retain separate counsel to participate in such defense, (iii) the
     indemnified party shall have the right to employ separate counsel at the
     expense of the indemnifying party and to control its own defense of such
     action, claim or proceeding if, in the reasonable opinion of counsel to
     such indemnified party, a material conflict or potential material conflict
     exists between the indemnified party and the indemnifying party that would
     make such separate representation advisable, except that in no event shall
     the indemnifying party be required to pay fees and expenses under this
     section 6 for more than one separate firm of attorneys in any one legal
     action or group of related legal actions.

          (b) No indemnifying party shall be liable for any settlement of any
     action or proceeding effected without its written consent, which consent
     shall not be unreasonably withheld. No indemnifying party shall, without
     the consent of the indemnified party, consent to entry of any judgment or
     enter into any settlement that does not include as an unconditional term
     thereof the giving by the claimant or plaintiff to such indemnified party
     of a release from all liability in respect to such claim or litigation.


                                       -10-

     6.4 Contribution. If indemnification shall for any reason be held by a
court to be unavailable to an indemnified party under section 6.1 or section 6.2
in respect of any loss, claim, damage or liability, or any action in respect
thereof, then, in lieu of the amount paid or payable under section 6.1 or
section 6.2, as applicable, the indemnified party and the indemnifying party
shall contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating the same), (i) in such proportion as is appropriate to reflect the
relative fault of the Company on the one hand and the Holders on the other hand
that resulted in such loss, claim, damage or liability, or action in respect
thereof, with respect to the statements or omissions that resulted in such loss,
claim, damage or liability, or action in respect thereof, as well as any other
relevant equitable considerations or (ii) if the allocation provided by item (i)
above is not permitted by applicable law, in such proportion as shall be
appropriate to reflect the relative benefits received by the Company on the one
hand and the Holders on the other provided, however, that no Holder shall have
any liability under this section 6.4 for any amount in excess of the net
proceeds actually received by such Holder from the sale of the Registrable
Securities included in such registration statement. No Person guilty of
fraudulent misrepresentation (within the meaning of the Securities Act) shall be
entitled to contribution from any Person who was not guilty of such fraudulent
misrepresentation. In addition, no Person shall be obligated to contribute
hereunder any amounts in payment for any settlement of any action or claim,
effected without such Person's consent, which consent shall not be unreasonably
withheld.

     6.5 Rule 144. With a view to making available the benefits of certain rules
and regulations of the Commission that may at any time permit the sale of the
Registrable Securities to the public without registration, at all times from and
after 90 days following the effective date of the first registration of the
Company under the Securities Act of an offering of its securities to the public,
the Company shall:

          (a) use its best efforts to facilitate the sale of the Registrable
     Securities to the public, without registration under the Securities Act,
     pursuant to Rule 144 promulgated under the Securities Act, provided that
     this shall not require the Company to file reports under the Securities Act
     and the Securities Exchange Act of 1934, or any similar federal statute,
     and the rules and regulations of the Commission thereunder ("Exchange
     Act"), at any time prior to the Company's being otherwise required to file
     such reports;

          (b) make and keep public information available, as those terms are
     understood and defined in Rule 144 promulgated under the Securities Act at
     all times after 90 days after the effective date of the first registration
     under the Securities Act filed by the Company for an offering of its
     securities to the general public;

          (c) use its best efforts to then file with the Commission in a timely
     manner all reports and other documents required of the Company under the
     Securities Act and the Exchange Act; and

          (d) deliver to the Holders, upon any Holder's request, a written
     statement as to whether it has complied with the requirements of this
     section 6, a copy of the most recent annual


                                       -11-

<PAGE>

     or quarterly report of the Company filed with the Commission or any stock
     exchange or self regulatory organization [registered under the Securities
     Exchange Act of 1934], and such other reports and documents so filed as a
     Holder may reasonably request to avail itself of any rule or regulation of
     the Commission allowing it to sell its Registrable Securities without
     registration.

     7. Representations and Warranties of the Company and the Stockholders. Each
of the Company, on the one hand, and the Stockholders, on the other hand, hereby
severally (and not jointly) represent and warrant to the Company and to each of
the Stockholders as set forth below (all of such representations and warranties

     limited by applicable bankruptcy, insolvency or other similar laws
     affecting the enforcement of creditors' rights generally and by general
     principles of equity relating to enforceability.

          (b) Power; Authorization; Non-Contravention. Each of the Company and
     the Stockholder, as applicable, has all power and authority to execute,

     necessary corporate or limited liability company, and if required,
