               4.1 REQUEST FOR REGISTRATION ON FORM OTHER THAN FORM S-3. Subject
to the terms of this Agreement, if the Company shall receive from the Initiating
Holders at any time after the earlier of January 31, 2001 or six months after
the effectiveness of the Company's initial public offering of shares of Common
Stock under a Registration Statement, a written request that the Company effect
any Registration with respect to all or a part of the Registrable Securities on
a Form other than Form S-3 for an offering with a reasonably anticipated
aggregate offering price to the public exceeding $10,000,000, the Company shall
(i) promptly give written notice of the proposed Registration to all other
Holders and shall (ii) as soon as practicable, use its best efforts to effect
Registration of the Registrable Securities specified in such request, together
with any Registrable Securities of any Holder joining in such request as are
specified in a written request given within 20 days after written notice from
the Company. The Company shall not be obligated to take any action to effect any
such registration pursuant to this Section 4.1 (i) during the period starting
with the date 60 days prior to the Company's estimated date of filing, and
ending on the date six months immediately following the effective date of a
Registration pertaining to securities of the Company (other than a registration
of securities in a Rule 145 transaction or with respect to an employee benefit
plan) provided that the Company is employing all reasonable efforts in good
faith to cause such Registration to become effective or (ii) after the Company
has effected one such Registration pursuant to this Section 4.1 and such
Registration has been declared effective.

               4.2 RIGHT OF DEFERRAL OF REGISTRATION. The Company shall not be
obligated to file a registration statement pursuant to this Section 4:

                           (i) in any particular jurisdiction in which the

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;

                                       4
<PAGE>   5

                           (ii) if the Company, within 10 days of the receipt of
the request of the Initiating Holders, gives notice of its bona fide intention
to effect the filing of a registration statement with the Commission within 60
days of receipt of such request (other than with respect to a registration
statement relating to a Rule 145 transaction or an offering solely to
employees), provided that the Company is actively employing in good faith all
reasonable efforts to cause such registration statement to become effective;

                           (iii) within six months immediately following the
effective date of any registration statement pertaining to the securities of the
Company (other than a registration of securities in a Rule 145 transaction or
with respect to an employee benefit plan); or

                           (iv) if the Company shall furnish to such Holders a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company or its shareholders for a registration statement to be filed in the
near future, then the Company's obligation to use its best efforts to file a
registration statement shall be deferred for a period not to exceed 120 days
from the receipt of the request to file such registration by such Holder
provided that the Company shall not exercise the right contained in this
paragraph (iv) more than once in any 12 month period.

               4.3 REQUEST FOR REGISTRATION ON FORM S-3. If the Initiating
Holders request that the Company file a Registration Statement on Form S-3 (or
any successor form to Form S-3) for a public offering of shares of Registrable
Securities the reasonably anticipated aggregate price to the public of which,
net of Selling Expenses, would not be less than $1,000,000, and the Company is a
registrant entitled to use Form S-3 to register the Registrable Securities for
such an offering, the Company shall use all reasonable efforts to cause such
Registrable Securities to be Registered for the offering on such form and to
cause such Registrable Securities to be qualified in such jurisdictions as the
Initiating Holders may reasonably request; provided, however, that the Company
shall not be required to effect more than two Registrations pursuant to this
Section 4.3 in any six month period. The substantive provisions of Section 4.5
shall be applicable to each registration initiated under this Section 4.3.

               4.4 REGISTRATION OF OTHER SECURITIES IN DEMAND REGISTRATION. Any
Registration Statement filed pursuant to the request of the Initiating Holders
under this Section 4 may, subject to the provisions of Section 4.5, include
securities of the Company other than Registrable Securities.

                                       5
<PAGE>   6

                        (a) NOTICE OF UNDERWRITING. If the Initiating Holders
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 4, and the Company shall include such
information in the written notice referred to in Section 4.1 or 4.3. The right
of any Holder to Registration pursuant to Section 4 shall be conditioned upon
such Holder's agreement to participate in such underwriting and the inclusion of
such Holder's Registrable Securities in the underwriting.

                        (b) INCLUSION OF OTHER HOLDERS IN DEMAND REGISTRATION.
If the Company, officers or directors of the Company holding Common Stock other
than Registrable Securities, or holders of securities other than Registrable
Securities, request inclusion in such Registration, the Initiating Holders, to
the extent they deem advisable and consistent with the goals of such
Registration, may, on behalf of all Holders, offer to any or all of the Company,
such officers or directors, and such holders of securities other than
Registrable Securities that such securities other than Registrable Securities be
included in the underwriting and may condition such offer on the acceptance by
such persons of the terms of this Section 5.

                                In the event, however, that the number of shares
so included exceeds the number of shares of Registrable Securities included by
all Holders, such Registration shall be treated as governed by Section 5 hereof
rather than Section 4, and it shall not count as a Registration for purposes of
Section 4.1 hereof.

                        (c) SELECTION OF UNDERWRITER IN DEMAND REGISTRATION. The
Company shall (together with all Holders proposing to distribute their
securities through such underwriting) enter into an underwriting agreement with
the representative ("Underwriter's Representative") of the underwriter or
underwriters selected for such underwriting by the Holders of a majority of the
Registrable Securities being registered by the Initiating Holders and agreed to
by the Company.

                        (d) MARKETING LIMITATION IN DEMAND REGISTRATION. In the
event the Underwriter's Representative advises the Initiating Holders in writing
that market factors (including, without limitation, the aggregate number of
shares of Common Stock requested to be Registered, the general condition of the
market, and the status of the persons proposing to sell securities pursuant to
the Registration) require a limitation of the number of shares to be
underwritten, then (i) first the Common Stock (other than Registrable
Securities) held by officers or directors of the Company, (ii) next the
securities other than Registrable Securities, and (iii) last the securities
requested to be registered by the Company, shall be excluded from such
Registration to not less than 20% of the securities included in such
Registration (based on aggregate market values). If a limitation of the number
of shares is still required, the Initiating Holders shall so advise

                                       6
<PAGE>   7

all Holders and the number of shares of Registrable Securities that may be
included in the Registration and underwriting shall be allocated among all
Holders in proportion, as nearly as practicable, to the respective amounts of
Registrable Securities entitled to inclusion in such Registration held by such
Holders at the time of filing the Registration Statement. No Registrable
Securities or other securities excluded from the underwriting by reason of this
Section 4.5(d) shall be included in such Registration Statement.

                        (e) RIGHT OF WITHDRAWAL IN DEMAND REGISTRATION. If any
Holder of Registrable Securities, or a holder of other securities entitled (upon
request) to be included in such Registration, disapproves of the terms of the
underwriting, such person may elect to withdraw therefrom by written notice to
the Company, the underwriter and the Initiating Holders delivered at least seven
days prior to the effective date of the Registration Statement. The securities
so withdrawn shall also be withdrawn from the Registration Statement.

               4.6 BLUE SKY IN DEMAND REGISTRATION. In the event of any
Registration pursuant to Section 4, the Company will exercise its reasonable
best efforts to Register and qualify the securities covered by the Registration
Statement under such other securities or Blue sky laws of such jurisdictions as
shall be reasonably appropriate for the distribution of such securities;
provided, however, that (i) the Company shall not be required to qualify to do
business or to file a general consent to service of process in any such states
or jurisdictions, and (ii) notwithstanding anything in this Agreement to the
contrary, in the event any jurisdiction in which the securities shall be
qualified imposes a non-waivable requirement that expenses incurred in
connection with the qualification of the securities be borne by selling
shareholders such expenses shall be payable pro rata by selling shareholders.

        5. PIGGYBACK REGISTRATION.

               5.1 NOTICE OF PIGGYBACK REGISTRATION AND INCLUSION OF REGISTRABLE
SECURITIES. Subject to the terms of this Agreement, if the Company decides to
Register any of its Common Stock (either for its own account or the account of a
security holder or holders exercising their respective demand registration
rights) on a form that would be suitable for a registration involving solely
Registrable Securities, the Company will: (i) promptly give 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) 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 delivered to the Company by any Holder within 15 days after
delivery of such written notice from the Company.

                                       7

               5.2 UNDERWRITING IN PIGGYBACK REGISTRATION.

               (a) NOTICE OF UNDERWRITING IN PIGGYBACK REGISTRATION. 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 5.1. In such event, the
right of any Holder to Registration shall be conditioned upon such underwriting
and the inclusion of such Holder's Registrable Securities in such underwriting
to the extent provided in this Section 5. All Holders proposing to distribute
their securities through such underwriting shall (together with the Company and
the other holders distributing their securities through such underwriting) enter
into an underwriting agreement with the Underwriter's Representative for such
offering. The Holders shall have no right to participate in the selection of the
underwriters for an offering pursuant to this Section 5.

               (b) MARKETING LIMITATION IN PIGGYBACK REGISTRATION. If the
Underwriter's Representative advises the Holders seeking registration of
Registrable Securities pursuant to Section 5 in writing that market factors
(including, without limitation, the aggregate number of shares of Common Stock
requested to be Registered the general condition of the market, and the status
of the person's proposing to sell securities pursuant to the Registration)
require a limitation of the number of shares to be underwritten, the
Underwriter's Representative (subject to the allocation priority set forth in
Section 5.2(c) may:

                        (i) in the case of the Company's initial Registered
public offering, exclude some or all Registrable Securities from such
registration and underwriting; and

                        (ii) in the case of any Registered public offering
subsequent to the initial public offering, limit the number of shares of
Registrable Securities to be included in such Registration and underwriting to
not less than 20% of the securities included in such Registration (based on
aggregate market values).

                (c) ALLOCATION OF SHARES IN PIGGYBACK REGISTRATION. If the
Underwriter's Representative limits the number of shares to be included in a
Registration pursuant to Section 5.2(b), the number of shares to be included in
such Registration shall be allocated (subject to Section 5.2(b)) in the
following manner: The shares (other than Registrable Securities) held by
officers or directors of the Company shall be excluded from such registration
and underwriting to the extent required by such limitation. If a limitation of
the number of shares is still required after such exclusion, the number of
shares that may be included in the Registration and underwriting by selling
shareholders shall be allocated among all Holders and other holders of
securities other than Registrable Securities requesting and legally entitled to
include shares in such Registration, in


                                       8
<PAGE>   9

proportion, as nearly as practicable, to the respective amounts of securities
(including Registrable Securities) which such Holders and such other holders
would otherwise be entitled to include in such Registration. No Registrable
Securities or other securities excluded from the underwriting by reason of this
Section 5.2(c) shall be included in the Registration Statement.

               (d) WITHDRAWAL IN PIGGYBACK REGISTRATION. If any Holder
disapproves of the terms of any such underwriting, such person may elect to
withdraw therefrom by written notice to the Company and the underwriter
delivered at least seven days prior to the effective date of the Registration
Statement. Any Registrable Securities or other securities excluded or withdrawn
from such underwriting shall be withdrawn from such Registration.

               (e) BLUE SKY IN PIGGYBACK REGISTRATION. In the event of any
Registration of Registrable Securities pursuant to this Section 5, the Company
will exercise its reasonable best efforts to Register and qualify the securities
covered by the Registration Statement under such other securities or Blue Sky
laws of such jurisdictions (not exceeding 20 unless otherwise agreed to by the
Company) as shall be reasonably appropriate for the distribution of such
securities; provided, however, that (i) the Company shall not be required to
qualify to do business or to file a general consent to service of process in any
such states or jurisdictions, and (ii) notwithstanding anything in this
Agreement to the contrary, in the event any jurisdiction in which the securities
shall be qualified imposes a non-waivable requirement that expenses incurred in
connection with the qualification of the securities be borne by selling
shareholders, such expenses shall be payable pro rata by selling shareholders.

        6. EXPENSES OF REGISTRATION.

                All Registration Expenses incurred in connection with one
Registration pursuant to Section 4 (other than a Registration on Form S-3), two
Registrations pursuant to Section 4.3 and unlimited Registrations pursuant to
Section 5, shall be borne by the Company. All Registration Expenses incurred in
connection with any other registration, qualification, or compliance, shall be
apportioned among the Holders and other holders of the securities so registered
on the basis of the number of shares so registered. Notwithstanding the above,
the Company shall not be required to pay for any expenses of any Registration
proceeding begun pursuant to Section 4 if the Registration request is
subsequently withdrawn at the request of the Holders of a majority of the
Registrable Securities to be registered (which Holders shall bear such
expenses), unless the Holders of a majority of the Registrable Securities agree
to forfeit their right to one demand registration pursuant to Section 4;
provided further, however, that if at the time of such withdrawal, the Holders
have learned of a Material Adverse Event with respect to the Company not known
to the Holders at the time of their request, then the Holders shall not


                                       9
<PAGE>   10

be required to pay any of such expenses and shall retain their rights pursuant
to Section 4. All Selling Expenses shall be borne by the holders of the
securities Registered pro rata on the basis of the number of shares Registered.

        7. REPORTS UNDER EXCHANGE ACT.

               With a view to making available to the Holders the benefits of
Rule 144 promulgated under the Securities Act and any other rule or regulation
of the Commission that may at any time permit a Holder to sell securities of the
Company to the public without registration or pursuant to a registration on Form
S-3, the Company agrees to:

                        (i) use its reasonable best efforts to make and keep
public information available, as those terms are understood and defined in
Commission Rule 144, at all times after 90 days after the effective date of the
first registration statement under the Act filed by the Company for the offering
of its securities to the general public;

                        (ii) take such action, including the voluntary
registration of its Common Stock under Section 12 of the Exchange Act as is
necessary to enable the Holders to utilize Form S-3 for the sale of their
Registrable Securities, such action to be taken as soon as practicable after the
end of the fiscal year in which the first registration statement filed by the
Company for offering of its securities to the general public is declared
effective;

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

                        (iv) furnish to any Holder, so long as the Holder owns
any Registrable Securities, forthwith upon request (i) a written statement by
the Company that it has complied with the reporting requirements of Commission
Rule 144 (at any time after 90 days after the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), the Securities Act and the Exchange Act (at any time after
it has become subject to such reporting requirements), or that it qualifies as a
registrant whose securities may be resold pursuant to Form S-3 (at any time
after it so qualifies), (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the
Company, and (iii) such other information as may be reasonably requested by a
Holder in availing itself of any rule or regulation of the Commission which
permits a Holder to sell any such securities without registration or pursuant to
such form.

        8. TERMINATION OF REGISTRATION RIGHTS.

                                       10
<PAGE>   11

                The rights to cause the Company to register securities granted
under Sections 4 and 5 of this Agreement shall terminate, with respect to each
Holder, on the earlier of (i) the date four years after the closing date of the
Company's initial public offering, (ii) upon such Holder holding less than 1% of
the outstanding Registrable Securities provided such Holder's Registrable
Securities can be sold pursuant to Rule 144 within a three-month period without
compliance with the registration requirements of the Securities Act.

        9. REGISTRATION PROCEDURES AND OBLIGATIONS.

               Whenever required under this Agreement to effect the registration
of any Registrable Securities, the Company shall, as expeditiously as reasonably
possible:

registered thereunder, keep such Registration Statement effective for up to 120
days.

                        (ii) Prepare and file with the Commission such
amendments and supplements to such Registration Statement and the prospectus
used in connection with such registration statement as may be necessary to
comply with the provisions of the Securities Act with respect to the disposition
of all securities covered by such Registration Statement.

                        (iii) Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                        (iv) Use its reasonable best efforts to register and
qualify the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdictions as shall be reasonably
requested by the Holders, provided that the Company shall not be required in
connection therewith or as a condition thereto to qualify to do business or to
file a general consent to service of process in any such states or
jurisdictions.

                        (v) In the event of any underwritten public offering,
enter into and perform its obligations under an underwriting agreement, in usual
and customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

<PAGE>   12

                        (vi) Notify each Holder 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 of 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 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) Provide a transfer agent and registrar for all
Registrable Securities registered pursuant to such Registration Statement and a
CUSIP number for all such Registrable Securities, in each case not later than
the effective date of such registration.

                        (viii) Furnish, at the request of any Holder requesting
registration of Registrable Securities pursuant to this Agreement, on the date
that such Registrable Securities are delivered to the underwriters for sale in
connection with a registration pursuant to this Agreement, (i) an opinion, dated
such date, of the counsel representing the Company for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters, if any, and to
the Holders, and (ii) a letter dated such date, from the independent certified
public accountants of the Company, in form and substance as is customarily given
by independent certified public accountants to underwriters in an underwritten
public offering, addressed to the underwriters.

        10. INFORMATION FURNISHED BY HOLDER.

               It shall be a condition precedent of the Company's obligations
under this Agreement that each Holder of Registrable Securities included in any
Registration furnish to the Company such information regarding such Holder and
the distribution proposed by such Holder or Holders as the Company may
reasonably request.

        11. INDEMNIFICATION.

                11.1 COMPANY'S INDEMNIFICATION OF HOLDERS. To the extent
permitted by law, the Company will indemnify each Holder, each of its officers,
directors, and constituent partners, legal counsel for the Holders, and each
person controlling such Holder, with respect to which Registration,
qualification, or compliance of Registrable Securities has been effected
pursuant to this Agreement, and each underwriter, if any, and each person who
controls any underwriter within the meaning of the Securities Act against all
claims, losses, damages, or liabilities (or actions in respect thereof) to the
extent such claims, losses, damages, or liabilities arise out of or are based
upon any untrue statement (or alleged untrue statement) of a material fact
contained in any


                                       12
<PAGE>   13

prospectus or other document (including any related Registration Statement)
incident to any such Registration, qualification, or compliance, or are based on
any omission (or alleged omission) to state therein a material fact requited to
be stated therein or necessary to make the statements therein not misleading, or
any violation or alleged violation by the Company of the Securities Act, the
Exchange Act, any state securities law, or any rule or regulation promulgated
under the Securities Act, the Exchange Act or any state securities law
applicable to the Company and relating to action or inaction required of the
Company in connection with any such Registration, qualification, or compliance;
and the Company will pay as incurred to each such Holder, each such underwriter,
and each person who controls any such Holder or underwriter or other party
entitled to indemnification herein, any legal and any other expenses reasonably
incurred in connection with investigating or defending any such claim, loss,
damage, liability, or action; provided, however, that the indemnity contained in
this Section 11.1 shall not apply to amounts paid in settlement of any such
claim, loss, damage, liability, or action if settlement is effected without the
consent of the Company (which consent shall not unreasonably be withheld); and
provided further, 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 upon any untrue statement or omission based upon written information
furnished to the Company by such Holder, underwriter, or other party entitled to
indemnification herein, or controlling person and stated to be for use in
connection with the offering of securities of the Company.

                11.2 HOLDER'S INDEMNIFICATION OF COMPANY. To the extent
permitted by law, each Holder will, if Registrable Securities held by such
Holder are included in the securities as to which such Registration,
qualification or, compliance is being effected pursuant to this Agreement,
indemnify the Company, each of its directors and officers, each legal counsel
and independent accountant of the Company, each underwriter, if any, of the
Company's securities covered by such a Registration Statement, each person who
controls the Company or such underwriter within the meaning of the Securities
Act, and each other such Holder, each of its officers, directors, and
constituent partners, and each person controlling such other Holder, against all
claims, losses, damages, and liabilities (or actions in respect thereof) arising
out of or based upon 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 or alleged violation by such
Holder of the Securities Act, the Exchange Act, any state securities law, or any
rule or regulation promulgated under the Securities Act, the Exchange Act or any
state securities law applicable to such Holder and relating to action or
inaction required of such Holder in connection with any such Registration,
qualification, or compliance, and will pay as incurred to the Company, such
Holders, such directors, officers, partners, persons, law


                                       13
<PAGE>   14

and accounting firms, underwriters or control persons, any legal and any other
expenses reasonably incurred in connection with investigating or defending any
such claim, loss, damage, liability, or action, in each case 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 in
connection with the offering of securities of the Company; provided, however,
that the indemnity contained in this Section 11.2 shall not apply to amounts
paid in settlement of any such claim, loss, damage, liability, or action if
settlement is effected without the consent of such Holder (which consent shall
not unreasonably be withheld); provided, further, that such Holder's liability
under this Section 11.2 shall not exceed such Holder's proceeds from the
offering of securities made in connection with such Registration.

               11.3 INDEMNIFICATION PROCEDURE. Promptly after receipt by an
indemnified party under this Section 11 of notice of the commencement of any
action, such indemnified party will, if a claim in respect thereof is to be made
against an indemnifying party under this Section 11, notify the indemnifying
party in writing of the commencement thereof and generally summarize such
action. The indemnifying party shall have the right to participate in and to
assume the defense of such claim; provided, however, that the indemnifying party
shall be entitled to select counsel for the defense of such claim with the
approval of any parties entitled to indemnification, which approval shall not be
unreasonably withheld; provided further, however, that if either party
reasonably determines that there may be a conflict between the position of the
Company and the Holders in conducting the defense of such action, suit, or
proceeding by reason of recognized claims for indemnity under this Section 11,
then counsel for such party shall be entitled to conduct the defense to the
extent reasonably determined by such counsel to be necessary to protect the
interest of such party. The failure to notify an indemnifying party promptly of
the commencement of any such action, if prejudicial to the ability of the
indemnifying party to defend such action, shall relieve such indemnifying party,
to the extent so prejudiced, of any liability to the indemnified party under
this Section 11, but the omission so to notify the indemnifying party will not
relieve such party of any liability that such party may have to any indemnified
party otherwise than under this Section 11.

                11.4 CONTRIBUTION. If the indemnification provided for in this
Section 11 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage, or expense
referred to therein, then the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the


                                       14
<PAGE>   15

relative fault of the indemnifying party on the one hand and of the indemnified
party on the other in connection with the statements or omissions that resulted
in such loss, liability, claim, damage, or expense as well as any other relevant
equitable considerations. The relative fault of the indemnifying party and of
the indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties, relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

               11.5 CONFLICTS. Notwithstanding the foregoing, to the extent that
the provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with an underwritten public offering are in
conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

               11.6 SURVIVAL. The obligations of the Company and Holders under
this Section 11 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Agreement or otherwise.

        12. LIMITATIONS ON REGISTRATION RIGHTS GRANTED TO OTHER SECURITIES.

               From and after the date of this Agreement, the Company shall not
enter into any agreement with any holder or prospective holder of any securities
of the Company providing for the granting to such holder of any information or
Registration rights, except that, with the consent of the Holders of a majority
of the aggregate of the Convertible Securities and Registrable Securities then
outstanding, additional holders may be added as parties to this Agreement with
regard to any or all securities of the Company held by them. Any such additional
parties shall execute a counterpart of this Agreement, and upon execution by
such additional parties and by the Company, shall be considered an Investor for
all purposes of this Agreement. The additional parties and the additional
Registrable Securities shall be identified in an amendment to Schedule A hereto.

        13. TRANSFER OF RIGHTS.

                The rights granted by the Company to the Investors under this
Agreement may be assigned by any Holder to a transferee or assignee of any
Convertible Securities or Registrable Securities not sold to the public
acquiring at least 10,000 shares of such Holder's Registrable Securities
(equitably adjusted for any stock splits, subdivisions, stock dividends,
changes, combinations or the like); provided, however, that (i) the shares of
Convertible Securities or Registrable Securities acquired by said transferee
must constitute at least 20% of Holder's aggregate of Convertible Securities and
Registrable Securities immediately prior to the transfer, (ii) the Company must
receive written notice


                                       15
<PAGE>   16

prior to the time of said transfer, stating the name and address of said
transferee or assignee and identifying the securities with respect to which such
information and Registration rights are being assigned, and (iii) the transferee
or assignee of such rights must not be a person deemed by the Board of Directors
of the Company, in its best judgment, to be a competitor or potential competitor
of the Company. Notwithstanding the limitation set forth in the foregoing
sentence respecting the minimum number of shares which must be transferred, any
Holder which is a partnership may transfer such Holder's Registration rights to
such Holder's constituent partners without restriction as to the number or
percentage of shares acquired by any such constituent partner.

        14. MARKET STAND-OFF.

               Each Holder hereby agrees that, if so requested by the
Underwriter's Representative (if any) in connection with the Company's initial
public offering, such Holder shall not sell, make any short sale of, loan, grant
any option for the purchase of, or otherwise transfer or dispose of any
Registrable Securities or other securities of the Company without the prior
written consent of the Company and the Underwriter's Representative for such
period of time (not to exceed 180 days) following the effective date of a
Registration Statement of the Company filed under the Securities Act as may be
requested by the Underwriter's Representative. The obligations of Holders under
this Section 14 shall be conditioned upon similar agreements being in effect
with each other shareholder who is an officer, director, or selling shareholder.

        15. NO-ACTION LETTER OR OPINION OF COUNSEL IN LIEU OF REGISTRATION;
CONVERSION OF PREFERRED STOCK.

               Notwithstanding anything else in this Agreement, if the Company
shall have obtained from the Commission a "no-action" letter in which the
Commission has indicated that it will take no action if, without Registration
under the Securities Act, any Holder disposes of Registrable Securities covered
by any request for Registration made under this Section in the specific manner
in which such Holder proposes to dispose of the Registrable Securities included
in such request (such as including, without limitation, inclusion of such
Registrable Securities in an underwriting initiated by either the Company or the
Holders), or if in the opinion of counsel for the Company concurred in by
counsel for such Holder, which concurrence shall not be unreasonably withheld,
no Registration under the Securities Act is required in connection with such
disposition, the Registrable Securities included in such request shall not be
eligible for Registration under this Agreement; provided, however, that any
Registrable Securities not so disposed of shall be eligible for Registration in
accordance with the terms of this Agreement with respect to other proposed
dispositions to which this Section 15 does not apply. The Registration rights of
the Holders of the Registrable Securities set forth in this Agreement are
conditioned upon the conversion of the Registrable Securities with respect to
which

                                       16
<PAGE>   17

Registration is sought into Common Stock prior to the effective date of the
Registration Statement.

        16. RIGHT OF FIRST REFUSAL.

                16.1 INVESTOR RIGHT OF FIRST REFUSAL. The Company hereby grants
to each Investor the right of first refusal to purchase its pro rata share of
New Securities that the Company may from time to time to time propose to sell
and issue after the date of this Agreement. For the issuance of New Securities,
such Investor's pro rata share is the ratio of the number of shares of Preferred
Stock owned by the Investor to the total number of shares of capital stock then
outstanding (assuming conversion into Common Stock of all Convertible
Securities).

               16.2 GENERAL CONDITIONS. If the Company proposes to undertake an
issuance of New Securities, it shall give the Investors written notice of its
intention, describing the type of New Securities, the price and the general
terms upon which the Company proposes to issue the same. The Investors shall
have 20 days from the date of mailing of any such notice to agree to purchase
their respective pro rata shares of such New Securities for the price, and upon
the general terms specified in the notice, by giving written notice to the
Company and stating therein the quantity of New Securities to be purchased.

        17. MISCELLANEOUS.

               17.1 ENTIRE AGREEMENT; SUCCESSORS AND ASSIGNS. This Agreement
constitutes the entire agreement between the Company and the Investors relative
to the subject matter hereof. Any previous agreements between the Company and
any Investor concerning Registration rights are superseded by this Agreement.
Subject to the exceptions specifically set forth in this Agreement, the terms
and conditions of this Agreement shall inure to the benefit of and be binding
upon the respective executors, administrators, heirs, successor, and assigns of
the parties.

               17.2 GOVERNING LAW. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of California excluding
those laws that direct the application of the laws of another jurisdiction.

               17.3 COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

               17.4 HEADINGS. The headings of the Sections of this Agreement are
for convenience and shall not by themselves determine the interpretation of this
Agreement.

<PAGE>   18

                17.5 NOTICES. Any notice to or from a U.S. or non-U.S. resident,
required or permitted hereunder shall be given in writing and shall be
conclusively deemed effectively given upon personal delivery, or (x) five days
after deposit in the United States mail, by registered or certified mail if to a
United States resident and (y) if to a party resident outside the United States,
ten days after the date of sending by first class courier, postage prepaid,
addressed (i) if to the Company, as set forth below the Company's name on the
signature page of this Agreement, and (ii) if to an Investor, at such Investor's
address as set forth on Schedule A, or at such other address as the Company or
such Investor may designate by 10 days' advance written notice to the Investors
or the Company, respectively.

               17.6 AMENDMENT OF AGREEMENT. Any provision of this Agreement may
be amended only by a written instrument signed by the Company and by persons
holding at least 60% of the Registrable Securities as defined in Section 1 of
this Agreement.
