                                                                               3


            (a) Right to Include Registrable Securities. If the Company at any
time after the date hereof proposes to register its Common Stock under the
Securities Act (other than a registration on Form S-4 or S-8, or any successor
or other forms promulgated for similar purposes), whether or not for sale for
its own account, pursuant to a registration statement on which it is permissible
to register Registrable Securities for sale to the public under the Securities
Act, it will each such time give prompt written notice to all Holders of
Registrable Securities of its intention to do so and of such Holders' rights
under this Section 3. Upon the written request of any such Holder made within 15
days after the receipt of any such notice (which request shall specify the
Registrable Securities intended to be disposed of by such Holder), the Company
will use its best efforts to effect the registration under the Securities Act of
all Registrable Securities which the Company has been so requested to register
by the Holders thereof; provided, that (i) 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 proceed with the proposed
registration of the securities to be sold by it, the Company may, at its
election, give written notice of such determination to each Holder of
Registrable Securities and, thereupon, shall be relieved of its obligation to
register any Registrable Securities in connection with such registration (but
not from its obligation to pay the Registration Expenses in connection
therewith), and (ii) if such registration involves an underwritten offering, all
Holders of Registrable Securities requesting to be included in the Company's
registration must sell their Registrable Securities to the underwriters selected
by the Company on the same terms and conditions as apply to the Company, with
such differences, including any with respect to indemnification and liability
insurance, as may be customary or appropriate in combined primary and secondary
offerings. If a registration requested pursuant to this Section 3(a) involves an
underwritten public offering, any Holder of Registrable Securities requesting to
be included in such registration may elect, in writing prior to the effective
date of the registration statement filed in connection with such registration,
not to register such securities in connection with such registration.

            (b) Expenses. The Company will pay all Registration Expenses in
connection with each registration of Registrable Securities requested pursuant
to this Section 3.

            (c) Priority in Incidental Registrations. If a registration pursuant
to this Section 3 involves an underwritten offering and the managing underwriter
advises the Company in writing that, in its opinion, the amount of securities
requested to be included in such registration exceeds the amount which can be
sold in such offering, so as to be likely to have an adverse effect on such
offering as contemplated by the Company (including the price at which the
Company proposes to sell such securities),


                                                                               4


then the Company will include in such registration (i) first, 100% of the
securities the Company proposes to sell, (ii) second, to the extent of the
amount of Registrable Securities requested to be included in such registration
which, in the opinion of such managing underwriter, can be sold without having
the adverse effect referred to above, the amount of Registrable Securities which
the Holders have requested to be included in such registration, such amount to
be allocated pro rata among all requesting Holders on the basis of the relative
number of shares of Registrable Securities then held by each such Holder
(provided that any Registrable Securities thereby allocated to any such Holder
that exceed such Holder's request will be reallocated among the remaining
requesting Holders in like manner).

            4. Registration on Request.

            (a) Request by Holders. Upon the written request of any Holder or
Holders who, in the aggregate, own at least 15% of the Registrable Securities
then outstanding that the Company effect the registration under the Securities
Act of all or part of such Holder's or Holders' Registrable Securities and
specifying the intended method of disposition thereof, the Company will promptly
give written notice of such requested registration to all other Holders of
Registrable Securities, and thereupon will, as expeditiously as possible, use
its best efforts to effect the registration under the Securities Act of:

            (i) the Registrable Securities which the Company has been so
      requested to register by such Holder or Holders; and

            (ii) all other Registrable Securities which the Company has been
      requested to register by any other Holder thereof by written request given
      to the Company within 15 days after the giving of such written notice by
      the Company (which request shall specify the intended method of
      disposition of such Registrable Securities),

so as to permit the disposition (in accordance with the intended method thereof
as aforesaid) of the Registrable Securities so to be registered; provided, that,
unless Holders of a majority of the Registrable Securities consent thereto in
writing, the Company shall not be obligated to file a registration statement
relating to any registration request under this Section 4(a) (i) unless the
aggregate requests by the Holder or Holders for such registration cover at least
15% of the number of Registrable Securities then outstanding or (ii) (other than
a registration statement on Form S-3 or any successor or similar short-form
registration statement) within a period of nine months after the effective date
of any other registration statement relating to (A) any registration request
under this Section 4(a) which was not effected on Form S-3 (or any successor or
similar short-form registration statement) or (B) any registration effected
under Section 3, or (iii) if with respect thereto, the managing underwriter, the
SEC, the Securities Act or the rules and


                                                                               5


regulations thereunder, or the form on which the registration statement is to be
filed, would require the conduct of an audit other than the regular audit
conducted by the Company at the end of its fiscal year, in which case the filing
may be delayed until the completion of such regular audit (unless the Holders of
the Registrable Securities to be registered agree to pay the expenses of the
Company in connection with such an audit other than the regular audit).

            (b) Registration Statement Form. If any registration requested
pursuant to this Section 4 which is proposed by the Company to be effected by
the filing of a registration statement on Form S-3 (or any successor or similar
short-form registration statement) shall be in connection with an underwritten
public offering, and if the managing underwriter shall advise the Company in
writing that, in its opinion, the use of another form of registration statement
is of material importance to the success of such proposed offering, then such
registration shall be effected on such other form.

            (c) Expenses. The Company will pay all Registration Expenses in
connection with the first 20 registrations of Registrable Securities pursuant to
this Section 4 upon the written request of any of the Holders. All expenses for
any subsequent registrations of Registrable Securities pursuant to this Section
4 shall be paid pro rata by the Company and all other Persons (including the
Holders) participating in such registration on the basis of the relative number
of shares of Common Stock of each such Person included in such registration.

            (d) Effective Registration Statement. A registration requested
pursuant to this Section 4 will not be deemed to have been effected unless it
has become effective; provided, that if, within 180 days after it has become
effective, the offering of Registrable Securities pursuant to such registration
is interfered with by any stop order, injunction or other order or requirement
of the SEC or other governmental agency or court, such registration will be
deemed not to have been effected.

            (e) Selection of Underwriters. If a requested registration pursuant
to this Section 4 involves an underwritten offering, the Company shall have the
right to select the investment banker or bankers and managers to administer the
offering; provided, however, that such investment banker or bankers and managers
shall be satisfactory to Holders of a majority of the Registrable Securities and
which the Company has been requested to register.

            (f) Priority in Requested Registrations. If a requested registration
pursuant to this Section 4 involves an underwritten offering and the managing
underwriter advises the Company in writing that, in its opinion, the number of
securities requested to be included in such registration (including securities
of the Company which are not Registrable Securities)


                                                                               6


exceeds the number which can be sold in such offering, the Company will include
in such registration only the Registrable Securities requested to be included in
such registration. In the event that the number of Registrable Securities
requested to be included in such registration exceeds the number which, in the
opinion of such managing underwriter, can be sold, the number of such
Registrable Securities to be included in such registration shall be allocated
pro rata among all requesting Holders on the basis of the relative number of
shares of Registrable Securities then held by each such Holder (provided that
any shares thereby allocated to any such Holder that exceed such Holder's
request shall be reallocated among the remaining requesting Holders in like
manner). In the event that the number of Registrable Securities requested to be
included in such registration is less than the number which, in the opinion of
the managing underwriter, can be sold, the Company may include in such
registration the securities the Company proposes to sell up to the number of
securities that, in the opinion of the underwriter, can be sold.

            (g) Additional Rights. If the Company at any time grants to any
other holders of Common Stock any rights to request the Company to effect the
registration under the Securities Act of any such shares of Common Stock on
terms more favorable to such holders than the terms set forth in this Section 4,
the terms of this Section 4 shall be deemed amended or supplemented to the
extent necessary to provide the Holders such more favorable rights and benefits.

            5. Registration Procedures. If and whenever the Company is required
to use its best efforts to effect or cause the registration of any Registrable
Securities under the Securities Act as provided in this Agreement, the Company
will, as expeditiously as possible:

            (i) prepare and, in any event within 120 days after the end of the
      period within which a request for registration may be given to the
      Company, file with the SEC a registration statement with respect to such
      Registrable Securities and use its best efforts to cause such registration
      statement to become effective; provided, however, that the Company may
      discontinue any registration of its securities which is being effected
      pursuant to Section 3 at any time prior to the effective date of the
      registration statement relating thereto;

            (ii) prepare and file with the SEC 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 for a period not in excess of 180 days and to comply with the
      provisions of the Securities Act with respect to the disposition of all
      securities covered by such registration statement during such period in
      accordance with the intended methods of


                                                                               7


      disposition by the seller or sellers thereof set forth in such
      registration statement; provided, that before filing a registration
      statement or prospectus, or any amendments or supplements thereto, the
      Company will furnish to one counsel selected by the Holders of a majority
      of the Registrable Securities covered by such registration statement to
      represent all Holders of Registrable Securities covered by such
      registration statement, copies of all documents proposed to be filed,
      which documents will be subject to the review of such counsel;

            (iii) furnish to each seller of such Registrable Securities such
      number of copies of such registration statement and of each amendment and
      supplement thereto (in each case including all exhibits), such number of
      copies of the prospectus included in such registration statement
      (including each preliminary prospectus and summary prospectus), in
      conformity with the requirements of the Securities Act, and such other
      documents as such seller may reasonably request in order to facilitate the
      disposition of the Registrable Securities by such seller;

            (iv) use its best efforts to register or qualify such Registrable
      Securities covered by such registration statement under such other
      securities or blue sky laws of such jurisdictions as each seller shall
      reasonably request, and do any and all other acts and things which may be
      reasonably necessary or advisable to enable such seller to consummate the
      disposition in such jurisdictions of the Registrable Securities owned by
      such seller, 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 where, but for the requirements of this clause (iv), it
      would not be obligated to be so qualified, to subject itself to taxation
      in any such jurisdiction, or to consent to general service of process in
      any such jurisdiction;

            (v) use its best efforts to cause such Registrable Securities
      covered by such registration statement to be registered with or approved
      by such other governmental agencies or authorities as may be necessary to
      enable the seller or sellers thereof to consummate the disposition of such
      Registrable Securities;

            (vi) notify each seller of any such Registrable Securities covered
      by such registration statement, at any time when a prospectus relating
      thereto is required to be delivered under the Securities Act within the
      appropriate period mentioned in clause (ii) of this Section 5, of the
      Company's becoming aware that the prospectus included in such registration
      statement, as then in effect, includes an untrue statement of a material
      fact or omits to state a material fact required to be stated therein or
      necessary to


                                                                               8


      make the statements therein not misleading in the light of the
      circumstances then existing, and at the request of any such seller,
      prepare and furnish to such seller a reasonable number of copies of an
      amended or supplemental prospectus as may be necessary so that, as
      thereafter delivered to the purchasers of such Registrable 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 then existing;

            (vii) otherwise use its best efforts to comply with all applicable
      rules and regulations of the SEC, and make available to its security
      holders, as soon as reasonably practicable (but not more than eighteen
      months) after the effective date of the registration statement, an
      earnings statement which shall satisfy the provisions of Section 11(a) of
      the Securities Act and the rules and regulations promulgated thereunder;

            (viii) use its best efforts to list such Registrable Securities on
      any securities exchange on which the Common Stock is then listed, if such
      Registrable Securities are not already so listed and if such listing is
      then permitted under the rules of such exchange, and to provide a transfer
      agent and registrar for such Registrable Securities covered by such
      registration statement not later than the effective date of such
      registration statement;

            (ix) enter into such customary agreements (including an underwriting
      agreement in customary form) and take such other actions as sellers of a
      majority of such Registrable Securities or the underwriters, if any,
      reasonably request in order to expedite or facilitate the disposition of
      such Registrable Securities;

            (x) obtain a "cold comfort" letter or letters from the Company's
      independent public accountants in customary form and covering matters of
      the type customarily covered by "cold comfort" letters as the seller or
      sellers of a majority of such Registrable Securities shall reasonably
      request (provided that Registrable Securities constitute at least 25% of
      the securities covered by such registration statement); and

            (xi) make available for inspection by any seller of such Registrable
      Securities covered by such registration statement, by any underwriter
      participating in any disposition to be effected pursuant to such
      registration statement and by any attorney, accountant or other agent
      retained by any such seller or any such underwriter, all pertinent
      financial and other records, pertinent corporate documents and properties
      of the Company, and cause all of the Company's officers, directors and
      employees to supply


                                                                               9


      all information reasonably requested by any such seller, underwriter,
      attorney, accountant or agent in connection with such registration
      statement.

            The Company may require each seller of Registrable Securities as to
which any registration is being effected to furnish the Company with such
information regarding such seller and pertinent to the disclosure requirements
relating to the registration and the distribution of such securities as the
Company may from time to time reasonably request in writing.

            Each Holder of Registrable Securities agrees that, upon receipt of
any notice from the Company of the happening of any event of the kind described
in clause (vi) of this Section 5, such Holder will forthwith discontinue
disposition of Registrable Securities pursuant to the registration statement
covering such Registrable Securities until such Holder's receipt of the copies
of the supplemented or amended prospectus contemplated by clause (vi) of this
Section 5, and, if so directed by the Company, such Holder will deliver to the
Company (at the Company's expense) all copies, other than permanent file copies
then in such Holder's possession, of the prospectus covering such Registrable
Securities current at the time of receipt of such notice. In the event the
Company shall give any such notice, the period mentioned in clause (ii) of this
Section 5 shall be extended by the number of days during the period from and
including the date of the giving of such notice pursuant to clause (vi) of this
Section 5 and including the date when each seller of Registrable Securities
covered by such registration statement shall have received the copies of the
supplemented or amended prospectus contemplated by clause (vi) of this Section
5.

            6. Indemnification.

            (a) Indemnification by the Company. In the event of any registration
of any securities of the Company under the Securities Act pursuant to Section 3
or 4, the Company will, and it hereby does, indemnify and hold harmless, to the
extent permitted by law, the seller of any Registrable Securities covered by
such registration statement, each affiliate of such seller and their respective
directors and officers or general and limited partners (and the partners,
members, directors, officers, affiliates and controlling Persons of each of the
foregoing) each other Person who participates as an underwriter in the offering
or sale of such securities and each other Person, if any, who controls such
seller or any such underwriter within the meaning of the Securities Act
(collectively, the "Indemnified Parties"), against any and all losses, claims,
damages or liabilities, joint or several, and expenses to which any such
Indemnified Party may become subject under the Securities Act, common law or
otherwise, insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof, whether or not such Indemnified Party is a party
thereto) arise out of or are based upon (a) any untrue statement or alleged


                                                                              10


untrue statement of any material fact contained in any registration statement
under which such securities were registered under the Securities Act, any
preliminary, final or summary prospectus contained therein, or any amendment or
supplement thereto, or (b) any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing, and the
Company will reimburse such Indemnified Party for any legal or any other
expenses reasonably incurred by it in connection with investigating or defending
any such loss, claim, liability, action or proceeding; provided, that the
Company shall not be liable to any Indemnified Party 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 any untrue statement
or alleged untrue statement or omission or alleged omission made in such
registration statement or amendment or supplement thereto or in any such
preliminary, final or summary prospectus in reliance upon and in conformity with
written information with respect to such seller furnished to the Company by such
seller for use in the preparation thereof; and provided, further, that the
Company will not be liable to any Person who participates as an underwriter in
the offering or sale of Registrable Securities or any other Person, if any, who
controls such underwriter within the meaning of the Securities Act, under the
indemnity agreement in this Section 6(a) with respect to any preliminary
prospectus or the final prospectus or the final prospectus as amended or
supplemented, as the case may be, to the extent that any such loss, claim,
damage or liability of such underwriter or controlling Person results from the
fact that such underwriter sold Registrable Securities to a person to whom there
was not sent or given, at or prior to the written confirmation of such sale, a
copy of the final prospectus (including any documents incorporated by reference
therein) or of the final prospectus as then amended or supplemented (including
any documents incorporated by reference therein), whichever is most recent, if
the Company has previously furnished copies thereof to such underwriter. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such seller or any other Indemnified Party and shall
survive the transfer of such securities by such seller.

            (b) Indemnification by the Seller. The Company may require, as a
condition to including any Registrable Securities in any registration statement
filed in accordance with Section 5 herein, that the Company shall have received
an undertaking reasonably satisfactory to it from the prospective seller of such
Registrable Securities or any underwriter to indemnify and hold harmless (in the
same manner and to the same extent as set forth in subdivision (a) of this
Section 6) the Company and all other prospective sellers or any underwriter, as
the case may be, with respect to any statement or alleged statement in or
omission or alleged omission from such registration statement, any preliminary,
final or summary prospectus contained therein, or


                                                                              11


any amendment or supplement, if such statement or alleged statement or omission
or alleged omission was made in reliance upon and in conformity with written
information with respect to such seller or underwriter furnished to the Company
by such seller or underwriter for use in the preparation of such registration
statement, preliminary, final or summary prospectus or amendment or supplement,
or a document incorporated by reference into any of the foregoing. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of the Company or any of the prospective sellers, or any of
their respective affiliates, directors, officers or controlling Persons and
shall survive the transfer of such securities by such seller.

            (c) Notices of Claims, Etc. Promptly after receipt by an indemnified
party hereunder of written notice of the commencement of any action or
proceeding with respect to which a claim for indemnification may be made
pursuant to this Section 6, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party, give written notice to the
latter of the commencement of such action; provided, that the failure of the
indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under the preceding subdivisions of this
Section 6, 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 such indemnified party's reasonable
judgment a conflict of interest between such indemnified and indemnifying
parties may exist in respect of such claim, the indemnifying party will 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, 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 other than reasonable costs of
investigation. No indemnifying party will consent to entry of any judgment or
enter into any settlement which does not include as an unconditional term
thereof, the giving by the claimant or plaintiff to such indemnified party of a
release from all liability in respect to such claim or litigation.

            (d) Other Indemnification. Indemnification similar to that specified
in the preceding subdivisions of this Section 6 (with appropriate modifications)
shall be given by the Company and each seller of Registrable Securities with
respect to any required registration or other qualification of securities under
any federal or state law or regulation or governmental authority other than the
Securities Act.


                                                                              12


            (e) Non-Exclusivity. The obligations of the parties under this
Section 6 shall be in addition to any liability which any party may otherwise
have to any other party.

            7. Rule 144. The Company covenants that it will 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 SEC thereunder (or, if the Company is not
required to file such reports, it will, upon the request of any Holder of
Registrable Securities, make publicly available such information), and it will
take such further action as any Holder of Registrable Securities may reasonably
request, all to the extent required from time to time to enable such Holder to
sell shares of Registrable Securities without registration under the Securities
Act within the limitation of the exemptions provided by (i) Rule 144 under the
Securities Act, as such Rule may be amended from time to time, or (ii) any
similar rule or regulation hereafter adopted by the SEC. Upon the request of any
Holder of Registrable Securities, the Company will deliver to such Holder a
written statement as to whether it has complied with such requirements.
Notwithstanding anything contained in this Section 7, the Company may deregister
under Section 12 of the Exchange Act if it then is permitted to do so pursuant
to the Exchange Act and the rules and regulations thereunder.

            8. Miscellaneous.

            (a) Other Investors. The Company may enter into agreements with
other purchasers of Common Stock who are then employees of the Company or any of
its subsidiaries making them parties hereto (and thereby giving them all of the
rights, preferences and privileges of an original party (other than the Company)
hereto) with respect to additional shares of Common Stock (the "Supplemental
Agreements"); provided that, pursuant to any such Supplemental Agreement, such
purchaser expressly agrees to be bound by all of the terms, conditions and
obligations of this Agreement as if such purchaser were an original party (other
than the Company) hereto; and further provided that such purchaser shall not
obtain any right to request registration under Section 4 hereof. All shares of
Common Stock issued or issuable pursuant to such Supplemental Agreements by such
purchasers shall be deemed to be Registrable Securities.

            (b) Holdback Agreement. If any such registration shall be in
connection with an underwritten public offering, each Holder of Registrable
Securities agrees not to effect any public sale or distribution, including any
sale pursuant to Rule 144 under the Securities Act, of any equity securities of
the Company, or of any security convertible into or exchangeable or exercisable
for any equity security of the Company (in each case, other than as part of such
underwritten public offering), within 7 days before or 90 days (or such lesser
period as the managing underwriters may permit) after the effective date of such
registration, and the Company hereby also so agrees and agrees to


                                                                              13


cause each other holder of any equity security, or of any security convertible
into or exchangeable or exercisable for any equity security, of the Company
purchased from the Company (at any time other than in a public offering) to so
agree.

            (c) Amendments and Waivers. This Agreement may be amended and the
Company may take any action herein prohibited, or omit to perform any act herein
required to be performed by it, only if the Company shall have obtained the
written consent to such amendment, action or omission to act, of the Holders of
a majority of the Registrable Securities then outstanding. Each Holder of any
Registrable Securities at the time or thereafter outstanding shall be bound by
any consent authorized by this Section 8(c), whether or not such Registrable
Securities shall have been marked to indicate such consent.

            (d) Successors, Assigns and Transferees. This Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective successors and assigns. In addition, and whether or not any express
assignment shall have been made, the provisions of this Agreement which are for
the benefit of the parties hereto other than the Company shall also be for the
benefit of and enforceable by any subsequent Holder of any Registrable
Securities, subject to the provisions contained herein.
