     3.  Registration Rights.
         -------------------

         3.1  Registration on Request.
              -----------------------

              (a) Request. Subject to Sections 3.6 and 3.8 hereof, at any time,
                  -------
and on not more than two (2) occasions, beginning on the date six months after
the closing of an initial public offering of equity securities of the Company,
upon the written request of the Investors or one or more holders (collectively,
the "Initiating Holders") of Registrable Securities representing not less than
fifty percent (50%) of the Registrable Securities, that the Company effect the
registration under the Securities Act of all or part of such Initiating Holders'
Registrable Securities, the Company shall promptly give written notice of such
requested registration to all holders of Registrable Securities, and thereupon
the Company shall 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 Initiating Holders, and

                  (ii) all other Registrable Securities which the Company has
been requested to register by the holders thereof (such holders together with
the Initiating Holders, the "Selling Holders") by written request given to the
Company within 30 days after the giving of such written notice by the Company,
all to the extent requisite to permit the disposition of the Registrable
Securities so to be registered.

              (b) Registration of Other Securities.  Whenever the Company shall
                  --------------------------------
effect registration pursuant to this Section 3.1 in connection with an
underwritten offering by one or more Selling Holders of Registrable Securities,
subject to Section 3.1(g) hereof, securities other than Registrable Securities
may be included among the securities covered by such registration.
<PAGE>

              (c) Registration Statement Form. Registrations under this Section
                  ---------------------------
3.1 shall be on such appropriate registration form of the Commission as shall be
selected by the Company.

              (d) Expenses.  The Company will pay the Registration Expenses in
                  --------
connection with any registration requested pursuant to this Section 3.1.

              (e) Effective Registration Statement.  A registration requested
                  --------------------------------
pursuant to this Section 3.1 shall not be deemed to have been effected (i)
unless a registration statement with respect thereto has become effective, (ii)
if after it has become effective, such registration is interfered with by any
stop order, injunction or other order or requirement of the Commission or other
governmental agency or court for any reason not primarily attributable to the
Selling Holders and has not thereafter become effective or (iii) the conditions
to closing specified in the underwriting agreement, if any, entered into in
connection with such registration are not satisfied or waived, other than by
reason of a failure on the part of the Selling Holders.

              (f) Selection of Underwriters. If the registration under this
                  -------------------------
Section 3.1 is in connection with an underwritten offering, the underwriter or
underwriters of each underwritten offering of the Registrable Securities so to
be registered shall be selected by the Company.

              (g) Priority in Requested Registration. Notwithstanding anything
                  ----------------------------------
in this Section 3.1 to the contrary, if the managing underwriter of any
underwritten offering shall advise the Company in writing (with a copy to each
Selling Holder) that, in its opinion, the number of securities requested to be
included in such registration exceeds the number which can be sold in such
offering within a price range acceptable to the Selling Holders of 66-2/3% of
the Registrable Securities requested to be included in such registration, then
the Company shall include in such registration, to the extent of the number
which the Company is so advised can be sold in (or during the time of) such
offering, first, Registrable Securities requested to be included in such
registration, pro rata among the Selling Holders requesting such registration on
the basis of the percentage of the Registrable Securities of such Selling
Holders requested so to be registered and, second, all other securities of the
Company requested to be included in such registration by any person other than a
Selling Holder (including the Company).

              (h) Limitations on Registration on Request. Notwithstanding
                  --------------------------------------
anything in this Section 3.1 to the contrary, in no event will the Company be
required to effect in the aggregate, without regard to the holder of Registrable
Securities making such request, more than two registrations pursuant to this
Section 3.1.

          3.2 Incidental Registration.
              -----------------------

              (a) Right to Include Registrable Securities. If the Company
                  ---------------------------------------
proposes to register any of its securities under the Securities Act by
registration on Form S-1, S-2 or S-3 or any successor or similar form(s) (except
registrations on such Forms or similar form(s) solely for registration of
securities in connection with an employee benefit plan or dividend reinvestment

                                      -2-
<PAGE>

plan or merger or consolidation or other acquisition by the Company of capital,
stock or assets), whether or not for sale for its own account, it will, subject
to Section 3.8 hereof, 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 3.2. Upon the written request of any such holder (a
"Requesting Holder") made as promptly as practicable and in any event within 10
days after the receipt of any such notice, which request shall specify the
Registrable Securities intended to be disposed of by such Requesting Holder, the
Company shall, subject to Sections 3.6 and 3.8 hereof, use reasonable efforts to
effect the registration under the Securities Act of all Registrable Securities
which the Company has been so requested to register by the Requesting Holders
thereof. 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 not to register,
shall be relieved of its obligation to register any Registrable Securities in
connection with such registration. No registration effected under this Section
3.2 shall relieve the Company of its obligation to effect the registration of
Registrable Securities upon request under Section 3.1. The Company shall pay all
Registration Expenses in connection with registration of Registrable Securities
requested pursuant to this Section 3.2.

              (b) Priority in Incidental Registrations. Notwithstanding anything
                  ------------------------------------
in paragraph (a) above to the contrary, if the managing underwriter of any
underwritten offering covered by paragraph (a) shall inform the Company in
writing of its belief that the number or type of Registrable Securities
requested to be included in such registration would materially and adversely
affect such offering, then the Company shall include in such registration, to
the extent of the number and type which the Company is so advised can be sold in
(or during the time of) such offering, first, all securities proposed by the
Company to be sold for its own account, second, Registrable Securities requested
to be included in such registration pro rata among the Requesting Holders on the
basis of the percentage of the aggregate Registrable Securities requested to be
so included and, third, all other securities of the Company requested to be
included in such registration by any person other than a Requesting Holder.

          3.3 Registration Procedures.  If and whenever the Company is required
              -----------------------
to effect the registration of any Registrable Securities under the Securities
Act as provided in Section 3.1 or 3.2, the Company shall as expeditiously as
possible:

                  (i) prepare and (as soon as practicable, and in any event
within 90 days after the end of the period within which requests for
registration may be given to the Company) file with the Commission the requisite
registration statement to effect such registration and thereafter use best
efforts to cause such registration statement to become effective; provided,
however, that the Company may discontinue any registration of its securities
which are not Registrable Securities at any time prior to the effective date cf
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

                                      -3-
<PAGE>

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 reasonably required for the disposition of all of such Registrable
Securities, provided, that such period need not exceed 180 days;

                  (iii) furnish to each seller of Registrable Securities covered
by such registration statement, 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 such seller may reasonably request;

                  (iv) use 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 sellers
of Registrable Securities covered by such registration statement 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 which may be reasonably necessary or advisable to enable such
sellers to consummate the disposition in such jurisdictions of the securities to
be sold by such sellers, 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 requirement of this paragraph
(iv), be obligated to be so qualified or to consent to general service of
process in any such jurisdiction;

                  (v) furnish to each seller and underwriter, if any, of
Registrable Securities a signed counterpart of

                  (x) an opinion of counsel for the Company, and

                  (y) if the registration statement covers an underwritten
public offering, a copy of a "comfort" letter signed by the independent public
accountants who have certified the Company's financial statements included or
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 accountants' comfort
letter, with respect to events subsequent to the date of such financial
statements, as are customarily covered in opinions of issuers' counsel and in
accountants' comfort letters, respectively, delivered to the underwriters in
underwritten public offerings of securities (and dated the dates such opinions
and comfort letters are customarily dated);

                  (vi) notify each seller of Registrable Securities covered by
such registration statement at any time 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

                                      -4-
<PAGE>

necessary to make the statements therein not misleading, in the light of the
circumstances under which they were made, and at the request of any such seller
promptly prepare and furnish to it 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 any purchaser 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; and

                  (vii) otherwise use its best efforts to comply with all
applicable rules and regulations of the Commission 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 such information
regarding such seller and the distribution of such securities as the Company may
from time to time reasonably request in writing.  The Company may exclude from
such registration any holder who fails to timely provide such information.

     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
Section 3.3(vi), such holder will forthwith discontinue such holder's
disposition of Registrable Securities pursuant to the registration statement
relating to such Registrable Securities until such holder's receipt of the
copies of the supplemented or amended prospectus contemplated by Section 3.3(vi)
and, if so directed by the Company, 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 relating to such Registrable Securities current at
the time of receipt of such notice.

          3.4  Underwritten Offerings.
               ----------------------

               (a) Requested Underwritten Offerings.  If requested by the
                   --------------------------------
underwriters for any underwritten offering by holders of Registrable Securities
pursuant to a registration requested under Section 3.1, the Company will enter
into an underwriting agreement with such underwriters for such offering, such
agreement to be satisfactory in substance and form to the Company and to contain
such representations and warranties by the Company and such other terms as are
generally prevailing in agreements of that type, including, without limitation,
indemnities to the effect and to the extent provided in Section 3.7. The holders
of the Registrable Securities proposed to be distributed by such underwriter
will cooperate with the Company in the negotiation of the underwriting
agreement.  Such holders of Registrable Securities shall, upon the request of
the Company, appoint a representative of such holders.  Such holders of
Registrable Securities to be distributed by such underwriter shall be parties to
such underwriting agreement.

               (b) Incidental Underwritten Offerings. If the Company proposes to
                   ---------------------------------
register any of its securities under the Securities Act as contemplated by
Section 3.2 and such securities are to be distributed by or though one or more
underwriters, the Company will, subject to Sections 3.2, 3.6 and 3.8 hereof, if
requested by any Requesting Holder of Registrable Securities, arrange for such
underwriters to include all the Registrable Securities to be offered and

                                      -5-
<PAGE>

sold by such Requesting Holder among the securities of the Company to be
distributed by such underwriters. Such holders of Registrable Securities shall,
upon the request of the Company, appoint a representative of such holders. The
holders of Registrable Securities to be distributed by such underwriters or
their representative shall be parties to the underwriting agreement between the
Company and such underwriters.

               (c) Holdback Agreements.  If any registration of Registrable
                   -------------------
Securities hereunder shall be in connection with an underwritten public
offering, each holder of Registrable Securities agrees not to effect any public
or private sale or distribution and not to effect any such sale or distribution
of any other equity security 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) during such
period of time as the managing underwriters retained by the Company, in their
business judgment, may request provided that each holder of Registrable
                               --------
Securities shall not be required to agree to any such "holdback" unless a
similar agreement is entered into with holders of all of the Company's equity
securities.

          3.5  Preparation; Reasonable Investigation.  In connection with the
               -------------------------------------
preparation and filing of each registration statement under the Securities Act
pursuant to this Agreement, the Company will give the holders of Registrable
Securities registered under such registration statement, the underwriters
thereof, 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
supplement thereto, and give each of them reasonable access to its books and
records, such opportunities to discuss the business of the Company with its
officers and the independent public accountants who have certified its financial
statements as shall be necessary, in the opinion of such holders' and such
underwriters' respective counsel, to conduct a reasonable investigation within
the meaning of the Securities Act, provided that such holders of Registrable
Securities and their respective attorneys agree in writing, subject to such
scope and exceptions as are customary in such circumstances, not to disclose or
use any confidential information any such holder receives in the exercise of its
rights under this Section 3.5.

          3.6  Limitations, Conditions and Qualifications to Obligations under
               ---------------------------------------------------------------
Registration Covenants.  The obligations of the Company to use best efforts to
----------------------
cause the Registrable Securities to be registered under the Securities Act is

               (a) The Company shall be entitled to postpone the filing of any
registration statement otherwise required to be prepared and filed by it
pursuant to Section 3.1(i) if the Company determines that such registration and
offering would interfere with any financing, acquisition, corporate
reorganization or other material transaction involving the Company or any of its
Affiliates or would require premature disclosures thereof, then for a period not
to exceed 120 days after the request therefor, and (ii) in the event the
registration is required to be filed during the fourth quarter of any fiscal
year and the underwriters require audited financials to be included in such
registration, then for a period not to exceed 120 days after the end of such
fiscal year.

                                      -6-
<PAGE>

               (b) In the event the Company determines to register securities
in an offering, whether pursuant to an underwritten public equity offering or an
acquisition, the Company, upon the advice of its underwriters, shall notify the
holders of Registrable Securities and (i) may request that such holders refrain
from selling Registrable Securities under Rule 144 and (ii) shall not be
obligated to file a registration statement to effect any registration,
qualification or compliance pursuant to Section 3.1, in each case for a period
of (A) up to 90 days after the closing of the underwriter's public offering or
acquisition or (B) immediately upon the Company's decision to no longer pursue
any such transaction (the "Black Out Period").

          3.7  Indemnification.
               ---------------

                                      -7-
<PAGE>

          (a) Indemnification by the Company.  In the event of any registration
              ------------------------------
of any securities of the Company under the Securities Act, the Company will, and
hereby does, indemnify and hold harmless, in the case of any registration
statement filed pursuant to Section 3.1 or 3.2 hereof, each seller of any
Registrable Securities covered by such registration statement, its directors,
officers, partners, agents and affiliates and 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, 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 registration statement under which such
securities were registered under the Securities Act, 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 will reimburse such seller and each such director, officer,
partner, agent or affiliate, underwriter and controlling Person for any legal or
any other 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 alleged untrue
statement or omission or alleged omission made in such registration statement,
any such preliminary prospectus, final prospectus, summary prospectus, amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company through an instrument executed by or on behalf of such
seller or underwriter, as the case may be, for use in the preparation thereof;
and provided, further, that the Company shall 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, 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. Such indemnity shall remain in full force
and effect regardless of any investigation made by or on behalf of such seller
or any such director, officer, partner, agent or affiliate or controlling Person
and shall survive the transfer of such securities by such seller.

          (b) Indemnification by the Sellers.  As a condition to including any
              ------------------------------
Registrable Securities in any registration statement, the Company shall have
received an undertaking satisfactory to it from the prospective seller of such
Registrable Securities to indemnify and hold harmless (in the same manner and to
the same extent as set forth in subdivision (a) of this Section 3.7) the Company
and its directors, officers, partners, agents and affiliates, and each other
person who participates as an underwriter in the offering or sale of such
Securities and each other person, if any, who controls the Company within the
meaning of the Securities Act, with respect to any statement or alleged
statement in or omission or alleged

                                      -8-
<PAGE>

omission from such registration statement, any preliminary prospectus, final
prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, if such statement or alleged statement or omission or
alleged omission was made in reliance upon and in conformity with written
information furnished to the Company through an instrument duly executed by such
seller for use in the preparation of such registration statement, preliminary
prospectus, final prospectus, summary prospectus, amendment or supplement. 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, partner,
agent or affiliate or controlling Person and shall survive the transfer of such
securities by such seller.

          3.8  Limitations on Registrations of Registrable Securities.  The
               ------------------------------------------------------
Company shall not be required to effect a particular registration of Registrable
Securities pursuant to Section 3.1 or 3.2 hereof if it shall deliver to the
holder or holders requesting such registration a written opinion of counsel to
the effect that the Registrable Securities requested by such holder to be so
registered may be sold in the U.S. public securities market without restriction
or registration under the Securities Act and any applicable state securities
laws. This limitation shall not affect any other Registrable Securities held by
such holder.

     4.   Rule 144.  With a view to making available the benefits of certain
          --------
rules and regulations of the Commission which may at any time permit the sale of

as the Company has a class of securities registered under the Exchange Act, the
Company agrees to:

               (a)  use reasonable efforts to file with the Commission in a
timely manner all reports and other documents required of the Company under the

          ----------------------
of the Company 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 beneficial owner or owners of at least 66-2/3% of the Registrable
Securities. Each beneficial owner of any Registrable Securities at the time or
thereafter outstanding shall be bound by any consent authorized by this Section
5, whether or not such Registrable Securities shall have been marked to indicate
such consent.

          portion of the Registrable Securities of any Holder or Holders joining

          that the Company shall not be obligated to effect, or take any action
          to effect, any such registration pursuant to this Section 2:

               (A)   in any particular jurisdiction in which the Company would
               be required to execute a general consent to service of process in
               effecting such registration, qualification or compliance, unless
               the Company is already subject to service in such jurisdiction
               and except as may be required by the Securities Act or applicable
               rules or regulations thereunder; or

               (B)   after the Company has effected one such registration
               pursuant to this Section 2(a) and such registration has been
               declared or ordered effective and the sales of such Registrable
               Securities shall have closed.

          Subject to the foregoing clauses (A) and (B), the Company shall file a
     registration statement covering the Registrable Securities so requested to
     be registered as soon as practicable after receipt of the request of
     Holders of 51% of the Eligible Shares.  Each Holder will have the right to
     participate ratably with the others.

          The registration statement filed pursuant to the request of CIBC may,
     subject to the provisions of Section 2(b) below, include other securities
     of the Company including securities of the Company which are held by
     persons who are entitled to include their securities in any such
     registration; provided, however, that, in any underwritten public offering
                   --------  -------
     contemplated by Sections 2, 3 and 5, the Holders of Eligible Shares shall
     be entitled to sell such Eligible Shares to the underwriters for conversion
     and sale of the shares of Common Stock issued upon conversion thereof,
     subject to agreement of the underwriters.

          The Company shall be entitled to postpone for a reasonable period of
     time not to exceed six months the filing of a registration statement
     otherwise required to be filed by it

                                      -4-
<PAGE>

     pursuant to this Section 2(a) if the Company determines, in its reasonable
     judgment, that such registration would materially interfere with any
     financing, acquisition, corporate reorganization or other material
     transaction involving the Company and the Company promptly gives written
     notice to the Holders who have initiated or elected to participate in such
     registration including an explanation thereof. The Company shall not
     exercise its right to defer a registration more than once in any 12-month
     period or in any event if the effect would be to permit a registration of
     securities (other than a registration that was pending at the time of the
     initial demand or a registration on Form S-4, Form S-8 or any successor or
     similar form) to the exclusion of such number of Registrable Securities as
     would otherwise have been included in the registration statement the filing
     of which was deferred.

          Holders requesting registration shall be entitled to withdraw any
     registration request made pursuant to this Section 2(a), provided, that
                                                              --------
     such registration request shall nevertheless be counted toward the number
     of registrations the Company is required to file pursuant to this Section
     2(a) unless the Holders reimburse the Company for all reasonable out-of-
     pocket costs incurred by the Company prior to such withdrawal.

          For purposes of provisions of Sections 2(a) and 5, registrations
     relative to which less than 50% of the offered securities are in fact sold
     shall not be included.

          (b)  Underwriting.
               ------------

                    (i)  If Holders requesting registration intend to distribute
          the Registrable Securities covered by their request by means of an
          underwriting, they shall so advise the Company as a part of their
          request made pursuant to this Section 2 and the Company shall include
          such information in the written notice referred to in Section 2(a)
          above. The right of any Holder to registration pursuant to Section
          2(a) shall be conditioned upon such Holder's participation in such
          underwriting and the inclusion of such Holder's Registrable Securities
          in the underwriting. A Holder may elect to include in such
          underwriting all or a part of the Registrable Securities he holds.

                    (ii) The Company (together with all Holders proposing to
          distribute their securities through such underwriting) shall enter
          into an underwriting agreement in customary form with the
          representative of the underwriter or underwriters selected for such
          underwriting by CIBC from the list of underwriters set forth on the
          attached Schedule I.  If any Holder of Registrable Securities who has
                   ----------
          requested inclusion in such registration as provided above disapproves
          of the terms of the underwriting, such person may elect to withdraw
          therefrom by written notice to the Company, the underwriter and CIBC.
          The securities so withdrawn shall also be withdrawn from registration.
          If the underwriter has not limited the number of Registrable
          Securities or other securities to be underwritten, the Company may
          include its securities for its own account in such registration if

                                      -5-
<PAGE>

          the underwriter so agrees and if the number of Registrable Securities
          and other securities which would otherwise have been included in such
          registration and underwriting will not thereby be limited or adversely
          affected.

               (iii)  Notwithstanding the provisions of this Section 2(b), if
          the underwriter determines that marketing factors require a limitation
          of the total number of shares of Common Stock to be underwritten or a
          limitation of the total number of shares of Common Stock to be sold by
          the Company, then, subject to the provisions of Section 6 herein, the
                                                          ---------
          number of shares to be included in the registration and the
          underwriting shall be allocated among all shareholders of the Company
          who are participating in such registration, on a pro rata basis based
          on the number of Registrable Securities or other shares of Common
          Stock of the Company held by all such Holders and being included in
          such registration; provided, that the number of shares of Registrable
                             --------
          Securities to be included in such underwriting and registration shall
          not be reduced unless all other securities included in such
          registration by the Company are first entirely excluded from the
          underwriting and registration.  No stock excluded from the
          underwriting by reason of the underwriter's marketing limitation shall
          be included in such registration.  If the Company determines not to
          participate in any such underwriting, it may elect to withdraw
          therefrom by written notice to the holders of Registrable Securities
          and the underwriter.  The securities so withdrawn from such
          underwriting shall also be withdrawn from such registration.

     3.   Company Registration.
          --------------------

          (a)  If the Company elects to register any of its securities for
     purposes of a public offering of securities of the Company (including, but
     not limited to, registration statements relating to secondary offerings of
     securities of the Company), other than a registration relating solely to
     employee benefit plans, a registration relating solely to a Commission Rule
     145 transaction, or a registration on any registration form which does not
     permit secondary sales or does not include substantially the same
     information as would be required to be included in a registration statement
     covering the sale of Registrable Securities, the Company will:

               (i)  promptly give to each Holder written notice thereof (which
          shall include a list of the jurisdictions in which the Company intends
          to attempt to qualify such securities under the applicable blue sky or
          other state securities laws) at least 30 days prior to the filing of
          any registration statement; and

               (ii) include in such registration (and any related qualification
          under blue sky laws or other compliance), and in any underwriting
          involved therein, all the Registrable Securities specified in a
          written request or requests, made by any Holder within 30 days after
          receipt of the written notice from the Company described in clause (i)
          above, except as set forth in Section 3(b) below.  Such

                                      -6-
<PAGE>

          written request may specify all or a part of a Holder's Registrable
          Securities. Each Holder desiring to include in any such registration
          statement all or any part of the Registrable Securities held by it
          shall, within 30 days after the above-described notice from the
          Company, so notify the Company in writing.

          (b)  Underwriting.  If the registration of which the Company gives
               ------------
     notice is for a registered public offering involving an underwriting, the
     Company shall so advise the Holders as a part of the written notice given
     pursuant to Section 3(a)(i).  In such event the right of any Holder to
     registration pursuant to Section 3(a) shall be conditioned upon such
     Holder's participation in such underwriting and the inclusion of the
     Registrable Securities such Holder elects to register in such underwriting
     to the extent provided herein.  All Holders proposing to distribute their
     securities through such underwriting shall (together with the Company)
     enter into an underwriting agreement in customary form with the underwriter
     or underwriters selected by the Company from the list attached as Schedule
                                                                       --------
     I hereto.  Notwithstanding the provisions of Section 3, if the underwriter
     -
     determines that marketing factors require a limitation of the total number
     of shares to be underwritten or a limitation of the total number of shares
     of Registrable Securities to be underwritten, the number of shares that may
     be included in the underwriting shall be allocated, first, to the Company;
     second, to the shareholders of the Company participating in the
     underwriting, on a pro rata basis subject to the provisions of Section 6
     herein.  No stock excluded from the underwriting by reason of the
     underwriter's marketing limitation shall be included in such registration.
     If any Holder of Registrable Securities determines not to participate in
     any such underwriting, such person may elect to withdraw therefrom by
     written notice to the Company and the underwriter.  The securities so
     withdrawn from such underwriting shall also be withdrawn from such
     registration.  Notwithstanding the foregoing provisions, the Company may
     withdraw any registration statement referred to in this Section 3 without
     thereby incurring any liability to the holders of Registrable Securities.

     4.   Expenses of Registration.  All Registration Expenses incurred in
          ------------------------
connection with any registration, qualification or compliance pursuant to this
Agreement shall be borne by the Company, and all Selling Expenses shall be borne
by the Holders of the securities so registered pro rata on the basis of the
number of their shares so registered.  The reasonable fees of counsel retained
by any selling Holders shall be borne by the Company.

     5.   Registration Procedures.  In the case of each registration effected by
          -----------------------
the Company pursuant to the provisions of this Agreement, the Company will keep
each Holder advised in writing as to the initiation of each registration and as
to the completion thereof.  At its expense, the Company will:

               (a)  prepare and file with the Commission a registration
     statement (which, in the case of an underwritten public offering pursuant
     to Section 2, shall be on Form S-1 or other form of general applicability
     satisfactory to the managing underwriter selected as therein provided) with
     respect to such securities and use its best efforts to cause such
     registration statement to become and remain effective for a period
     commencing on the

                                      -7-
<PAGE>

     effective date of such registration statement and ending on the earlier of
     the 90th day thereafter and the date on which all of such Registrable
     Securities have been disposed of;

          (b)  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 for the period specified in paragraph (a) above and
     comply with the provisions of the Securities Act with respect to the
     disposition of such Registrable Securities covered by such registration
     statement in accordance with the sellers' intended method of disposition
     set forth in such registration statement for such period;

          (c)  furnish to each seller of Registrable Securities and to each
     underwriter such number of copies of the registration statement and the
     prospectus included therein (including each preliminary prospectus) as such
     persons reasonably may request in order to facilitate the public sale or
     other disposition of the Registrable Securities covered by such
     registration statement;

          (d)  use its best efforts to register or qualify the Registrable
     Securities covered by such registration statement under the securities or
     "blue sky" laws of such jurisdictions as the sellers of Registrable
     Securities or, in the case of an underwritten public offering, the managing
     underwriter reasonably shall request; provided, however, that the Company
                                           --------  -------
     shall not for any such purpose under this clause (d) be required to qualify
     generally to transact business as a foreign corporation in any jurisdiction
     where it is not so qualified or to consent to general service of process in
     any such jurisdiction;

          (e)  use its best efforts to list the Registrable Securities covered
     by such registration statement with any securities exchange on which the
     Common Stock of the Company is then listed;

          (f)  immediately notify each seller of Registrable Securities and each
     underwriter under such registration statement, at any time when a
     prospectus relating thereto is required to be delivered under the
     Securities Act, of the happening of any event of which the Company has
     knowledge as a result of which the prospectus contained 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 make the statements therein not misleading in light
     of the circumstances then existing and the Company will prepare a
     supplement or amendment to such prospectus in order that such prospectus
     will not contain an untrue statement of a material fact or omit to state
     any material fact required to be stated therein or necessary to make the
     statements therein not misleading;

          (g)  if the offering is underwritten and at the request of any seller
     of Registrable Securities, use its best efforts to furnish in the date that
     Registrable Securities are delivered to the underwriters for sale pursuant
     to such registration: (i) an opinion dated

                                      -8-
<PAGE>

     such date of counsel representing the Company for the purposes of such
     registration, addressed to the underwriters and to such seller, stating
     that such registration statement has become effective under the Securities
     Act and that (A) to the best knowledge of such counsel, no stop order
     suspending the effectiveness thereof has been issued and no proceedings for
     that purpose have been instituted or are pending or contemplated under the
     Securities Act, (B) the registration statement, the related prospectus and
     each amendment or supplement thereof comply as to form in all material
     respects with the requirements of the Securities Act (except that such
     counsel need not express any opinion as to financial statements contained
     therein) and (C) to such other effects as reasonably may be requested by
     counsel for the underwriters or by such seller or its counsel and (ii) a
     letter dated such date from the independent public accountants retained by
     the Company, addressed to the underwriters and to such seller, stating that
     they are independent public accountants within the meaning of the
     Securities Act and that, in the opinion of such accountants, the financial
     statements of the Company included in the registration statement or the
     prospectus, or any amendment or supplement thereof, comply as to form in
     all material respects with the applicable accounting requirements of the
     Securities Act, and such letter shall additionally cover such other
     financial matters (including information as to the period ending no more
     than five Business Days prior to the date of such letter) with respect to
     such registration as such underwriters reasonably may request;

          (h)  make available for inspection by each seller of Registrable
     Securities, any underwriter participating in any distribution pursuant to
     such registration statement, and any attorney, accountant or other agent
     retained by such seller or underwriter, all financial and other records,
     pertinent corporate documents and properties of the Company, and cause the
     Company's officers, directors and employees to supply all information
     reasonably requested by any such seller, underwriter, attorney, accountant
     or agent in connection with such registration statement;

          (i)  cause all Registrable Securities covered by the registration
     statement to be listed on each securities exchange on which the Company's
     Common Stock is then listed, and unless the same already exists, provide a
     transfer agent, registrar and CUSIP number for all such Registrable
     Securities not later than the effective date of the registration statement;
     and

          (j)  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 covering a period of 12
     months, beginning within three months after the effective date of the
     registration statement, which earnings statement shall satisfy the
     provisions of Section 11(a) of the Securities Act and Rule 158 thereunder.

     Each Holder agrees that, upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 5(f), such Holder will,
as soon as is practical, discontinue disposition of its Registrable Securities
until such Holder's receipt of the copies of the supplemented or amended
prospectus covering such Registrable Securities.

                                      -9-
<PAGE>

     In connection with each registration hereunder, the sellers of Registrable
Securities will furnish to the Company in writing such information with respect
to themselves and the proposed distribution by them as reasonably shall be
necessary in order to assure compliance with federal and applicable state
securities laws.

     In connection with each registration pursuant to Sections 2, 3 or 5
covering an underwritten public offering, the Company and each seller agree to
enter into a written agreement with the managing underwriter selected in the
manner herein provided in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
underwriter and companies of the Company's size and investment stature.

     6.   Secondary Offering Priority.  Up to fifty percent (50%) of the number
          ---------------------------
of shares available to be sold in any secondary offering of the Company's Common
Stock permitted to be included by the Company's underwriters in conjunction with
an Initial Public Offering and up to fifty percent (50%) of the number of shares
available to be sold in each subsequent offering of the Company's common stock
permitted to be included therein by the Company's underwriters shall be reserved
for Holders under Section 2 until such time as Holders, as a group, have been
afforded the opportunity to include fifty percent (50%) of their Conversion
Shares through such offerings or any other registered underwritten offering
available to such Holders; provided, however, that the number of Registrable
Securities to which the foregoing priority is afforded shall not be greater than
the difference between fifty percent (50%) of the Conversion Shares and the
number of Conversion Shares as to which the opportunity to sell in any such
offerings had been made available.

     7.   Indemnification.
          ---------------

               (a)  The Company will indemnify each Holder, each of its
     officers, directors, shareholders, employees, agents and partners, and each
     other person controlling such Holder, with respect to which registration,
     qualification or compliance has been effected pursuant to this Agreement,
     and each underwriter, if any, and each person who controls any underwriter,
     against all claims, losses, damages and liabilities (or action in respect
     thereof) arising out of or based on any untrue statement (or alleged untrue
     statement) of a material fact contained in any prospectus, offering
     circular or other document (including any related registration statement,
     notification or the like) incident to any such registration, qualification
     or compliance, or based on any omission (or alleged omission) to state
     thereto a material fact required to be stated therein or necessary to make
     the statements therein not misleading, or any violation by the Company of
     the Securities Act, the Exchange Act, any rule or regulation thereunder, or
     any other federal or state securities laws applicable to the Company and
     relating to action or inaction required of the Company in connection with
     any such registration, qualification or compliance, and will reimburse each
     such Holder, each of its officers, directors, shareholders, employees,
     agents and partners, and each other person controlling such Holder, each
     such underwriter and each person who controls any such underwriter, for any
     legal and any other expenses

                                      -10-
<PAGE>

     reasonably incurred in connection with investigating and defending any such
     claim, loss, damage, liability or action, including any of the foregoing
     incurred in settlement of any litigation commenced or threatened; provided,
                                                                       --------
     however, that the Company will not be liable in any such case to the extent
     -------
     that any such claim, loss, damage, liability or expense arises out of or is
     based on any untrue statement or omission based upon written information
     furnished to the Company by such Holder or underwriter and stated to be
     specifically for use therein; and provided further, however, that the
                                       -------- -------  -------
     indemnity agreement contained in this Section 7(a) will not apply to
     amounts paid in settlement if such settlement is effected without the
     consent of the Company (which consent will not be unreasonably withheld).
     Such indemnity shall remain in full force and effect regardless of any
     investigation made by or on behalf of any Holder or any such director,
     officer, partner, agent, Affiliate, shareholders, underwriters, employees
     or control persons and shall survive the transfer of such securities by the
     Company.

          (b)  Each Holder will, if Registrable Securities held by him are
     included in the securities as to which such registration, qualifications or
     compliance is being effected, severally and not jointly, indemnify the
     Company, each of its directors, shareholders, employees, agents and
     officers and each underwriter, if any, of the Company's securities covered
     by such a registration statement, each other person who controls the
     Company or such underwriter within the meaning of the Securities Act, the
     Exchange Act, any rule or regulation thereunder, or any other federal or
     state securities laws and the rules and regulations thereunder, each such
     other Holder and each of their officers, directors, shareholders,
     employees, agents and partners, and each other person controlling such
     Holder, against all claims, losses, damages and liabilities (or actions in
     respect thereof) arising out of or based on any untrue statement (or
     alleged untrue statement) of a material fact contained in any such
     registration statement, prospectus, offering circular or other document, or
     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 or any violation by such Holder of the Securities Act, the
     Exchange Act, any rule or regulation thereunder, or any other federal or
     state securities laws applicable to such Holder and relating to action or
     in action required of such Holder in connection with any such registration,
     qualification or compliance, and will reimburse the Company and any other
     Holder, and each of their directors, officers, partners, underwriters,
     shareholders, employees, agents or control persons for any legal or any
     other expenses reasonably incurred in connection with investigating or
     defending any such claim, loss, damage, liability or action, including any
     of the foregoing incurred in settlement of any litigation commenced or
     threatened, in each case to the extent, but only to the extent, that such
     untrue statement (or alleged untrue statement) or omission (or alleged
     omission) is made in such registration statement, prospectus, offering
     circular or other document in reliance upon and in conformity with written
     information furnished to the Company by such Holder and stated to be
     specifically for use therein; provided, however, that the obligations of
                                   --------  -------
     such Holders hereunder shall be limited to an amount equal to the net
     proceeds to each such Holder of securities sold as contemplated herein; and
     provided further, however, that the indemnity agreement contained in this
     -------- -------  -------
     Section 7(b) will not

                                      -11-
<PAGE>

     apply to amounts paid in settlement if such settlement is effected without
     the consent of the majority of the Holders (which consent will not be
     unreasonably withheld). 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, partner, agent, or Affiliate, shareholders,
     underwriters, employees or control persons and shall survive the transfer
     of such securities by such Holder.

          (c)  Promptly after receipt by an indemnified party hereunder of
     notice of the commencement of any action, such indemnified party shall, if
     a claim in respect thereof is to be made against the indemnifying party
     hereunder, notify the indemnifying party in writing thereof, but the
     omission so to notify the indemnifying party shall not relieve it from any
     liability which it may have to such indemnified party other than under this
     Section 7 and shall only relieve it from any liability which it may have to
     such indemnified party under this Section 7 if and to the extent the
     indemnifying part is prejudiced by such omission.  In case any such action
     shall be brought against any indemnified party and it shall notify the
     indemnifying party of the commencement thereof, the indemnifying party
     shall be entitled to participate in and, to the extent it shall wish, to
     assume and undertake the defense thereof with counsel satisfactory to such
     indemnified party, and, after notice from the indemnifying party to such
     indemnified party of its election so to assume and undertake the defense
     thereof, the indemnifying party shall not be liable to such indemnified
     party under this Section 7 for any legal expenses subsequently incurred by
     such indemnified party in connection with the defense thereof other than
     reasonable costs of investigation and of liaison with counsel so selected
     as incurred; provided, however, that, if the defendants in any such action
                  --------  -------
     include both the indemnified party and the indemnifying party and the
     indemnified party shall have reasonably concluded that there may be
     reasonable defenses available to it which are different from or additional
     to those available to the indemnifying party or if the interests of the
     indemnified party reasonably may be deemed to conflict with the interests
     of the indemnifying party, the indemnified party shall have the right to
     select a separate counsel and to assume such legal defenses and otherwise
     to participate in the defense of such action, with the expenses and fees of
     such separate counsel and other expenses related to such participation to
     be reimbursed by the indemnifying party as incurred.

          (d)  In order to provide for just and equitable contribution to joint
     liability under the Securities Act in any case in which either (i) any
     Holder exercising rights under this Agreement, or any controlling person of
     any such Holder, makes a claim for indemnification pursuant to this Section
     7 but it is judicially determined (by the entry of a final judgment or
     decree by a court of competent jurisdiction and the expiration of time to
     appeal or the denial of the last right of appeal) that such indemnification
     may not be enforced in such case notwithstanding the fact that this Section
     7 provides for indemnification in such case, or (ii) contribution under the
     Securities Act may be required on the part of any such selling Holder or
     any such controlling person in circumstances for which indemnification is
     provided under this Section 7; then, and in each such case, the Company and
     such Holder will contribute to the aggregate losses, claims, damages or

                                      -12-
<PAGE>

     liabilities to which they may be subject (after contribution from others)
     in such proportion so that such Holder is responsible for the portion
     represented by the percentage that the public offering price of its
     Registrable Securities offered by the registration statement bears to the
     public offering price of all securities offered by such registration
     statement, and the Company is responsible for the remaining portion;
     provided, however, that, in any such case, (A) no such Holder will be
     --------  -------
     required to contribute any amount in excess of the price to the
     underwriters of all such Registrable Securities offered by it pursuant to
     such registration statement; and (B) no person or entity guilty of
     fraudulent misrepresentation (within the meaning of Section 11(f) of the

     general public), and of the Securities Act and the Exchange Act (at any
     time after it has become subject to such reporting requirements), a copy of
     the most recent annual or quarterly report of the Company, and such other
     reports and documents so filed as a purchaser of Eligible Shares may
     reasonably request in availing itself of any rule or regulation of the
     Commission allowing a purchaser of Eligible Shares to sell any such
     securities without registration.

     12.  Representation and Warranties of the Company.  The Company represents
          --------------------------------------------

     creditors' rights generally and to applicable laws affecting the
     enforceability of indemnification and contribution).

     13.  Transfer or Assignment of Registration Rights.  The rights to cause
          ---------------------------------------------
the Company to register a Holder's securities granted to each Holder by the
Company under Sections 2, 3, and 5 may be transferred or assigned by a Holder to
a transferee or assignee of any of such Holder's Registrable Securities if (i)

     agreements.

          (e) Severability.  If any provision of this Agreement shall be held to
              ------------
     be illegal, invalid or unenforceable, such illegality, invalidity or
     unenforceability shall attach only to such provision and shall not in any
     manner affect or render illegal, invalid or unenforceable any other
     provision of this Agreement, and this Agreement shall be carried out as if
     any such illegal, invalid or unenforceable provision where not contained
     herein.

          (f) Entire Agreement.  This Agreement, as restated herein, and the
              ----------------
     other instruments referred to herein contain the entire agreement among the
     parties with respect to the registration rights of holders of Eligible
     Shares and supersede all prior and contemporaneous arrangements or
     understandings with respect thereto.  Each Holder who is not a signatory to
     this Agreement shall be deemed to be an intended third party beneficiary
     hereof and shall be entitled to enforce all rights, preferences and
     privileges afforded to such Holders hereunder.

          (g) Counterparts.  This Agreement may be executed in counterparts,
              ------------

     no such waiver shall be effective unless set forth in a written instrument
     duly executed by or on behalf of the party waiving such term or condition
     (and no such waiver shall in any event be binding on any other party hereto
     that is entitled to the benefits of such term or provision).  No waiver by
     any party hereto of any term or condition of this Agreement, in any one or
     more instances, shall be deemed to be or construed as a waiver of the same
     or any other term or condition of this Agreement on any future occasion.
     All remedies, either under this Agreement or by law or otherwise afforded,
     will be cumulative and not alternative.

          (i) Third Party Beneficiaries.  The terms and provisions of this
              -------------------------
     Agreement are intended solely for the benefit of each party hereto (and any
     additional Holders who execute a Joinder Agreement) and their respective
     successors and permitted transferees, and it is not the intention of the
     parties to confer third-party beneficiary rights, and this Agreement does
     not confer any such rights, upon any other Person other than any Person
     entitled to indemnity under Section 7.

          (j) Public Notices.  All public notices to third parties and all other
              --------------

     be jointly planned and coordinated by the parties hereto and no party shall
     act unilaterally in this regard without the prior approval of the other
     party, such approval not to be unreasonably withheld, except:

          or

               (ii)  where required to do so by law or by the applicable
          regulations or policies of any United States or other regulatory
          agency of competent jurisdiction or any stock exchange in
          circumstances where prior consultation with the other parties is not
          practicable.

          (k)  Further Assurances.  Each of the parties covenants and agrees to
               ------------------
     take all such action and to execute all such documents as may be necessary
     or advisable to implement the provisions of this Agreement fully and
     effectively and to make them binding on the parties hereto.
