disposition of all or any portion of the Registrable Securities unless and until
the transferee has agreed in writing for the benefit of the Company to be bound
by this Section 2.1, provided and to the extent such Section is then applicable,
and:

                   (a)  There is then in effect a registration statement under
the Securities Act covering such proposed disposition and such disposition is
made in accordance with such registration statement; or

                   (b)  (i) Such Holder shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii) if
reasonably requested by the Company, such Holder shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that

                   ------

laws):

          THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE

          TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL

          ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED. THIS CERTIFICATE
          MUST BE SURRENDERED TO THE COMPANY OR ITS TRANSFER AGENT AS A
          CONDITION PRECEDENT TO ANY TRANSFER OF ANY INTEREST IN THE SHARES

<PAGE>

                   (b)  The Company shall be obligated to reissue promptly
unlegended certificates at the request of any holder thereof if the holder shall
have obtained an opinion of counsel at such Holder's expense (which counsel may
be counsel to the Company) reasonably acceptable to the Company to the effect
that the securities proposed to be disposed of may lawfully be so disposed of
without registration, qualification or legend, and such opinion and the
certificate representing the shares to be transferred have been delivered to the
Company or its transfer agent.

                   (c)  Any legend endorsed on an instrument pursuant to
applicable state securities laws and the stop-transfer instructions with respect
to such securities shall be removed upon receipt by the Company of an order of
the appropriate blue sky authority authorizing such removal.

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

              3.1      Demand Registration Rights.
                       --------------------------

                       (a)  Request for Registration.  If at any time after six
                            ------------------------
(6) months after the effective date of the first registration statement filed by
the Company covering an underwritten public offering of shares of Common Stock,
the Company shall receive from Initiating Holders a written request that the
Company effect a registration covering an underwritten public offering of all or
a part of the Registrable Securities, the aggregate proceeds of which offering
(after deduction for underwriter's discounts and expenses related to the
issuance) are at least $5,000,000 the Company will:

                            (i)  Promptly give written notice of the proposed
registration to all other Holders; and

                            (ii) As soon as practicable, use its best efforts to
effect such registration (including, without limitation, filing post-effective
amendments, appropriate qualifications under applicable blue sky or other state
securities laws and appropriate compliance with the Securities Act) and as would
permit or facilitate the sale and distribution of all or such portion of such
Registrable Securities as are specified in such request, together with all or
such portion of the Registrable Securities of any Holder or Holders joining in
such request as are specified in a written request received by the Company
within twenty (20) days after such written notice from the Company is mailed or
delivered.

                   The Company shall not be obligated to effect, or to take any
action to effect, any such registration pursuant to this Section 3.1:

                            (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;

                            (B)  After the Company has initiated three (3) such
registrations pursuant to this Section 3.1(a) (counting for these purposes only
registrations which have been declared or ordered effective and pursuant to
which securities have been sold and registrations which have been withdrawn by
the Holders as to which the Holders have not elected to bear the

                                      -4-
<PAGE>

Registration Expenses pursuant to Section 3.4 hereof and would, absent such
election, have been required to bear such expenses);

                            (C)  During the period starting with the date sixty
(60) days prior to the Company's good faith estimate of the date of filing of,
and ending on a date one hundred eighty (180) days after the effective date of,
a Company-initiated registration; provided that the Company is actively
                                  --------
employing in good faith all reasonable efforts to cause such registration
statement to become effective;

                            (D)  If the Initiating Holders propose to dispose of
Registrable Securities which may be immediately registered on Form-S-3 pursuant
to a request made under Section 3.3 hereof;

                            (E)  If the Initiating Holders do not request that
such offering be firmly underwritten by underwriters selected by the Initiating
Holders (subject to the consent of the Company, which consent will not be
unreasonably withheld); or

                            (F)  If the Company and the Initiating Holders are
unable to obtain the commitment of the underwriter in clause (E) above to firmly
underwrite the offer.

                       (b)  Subject to the foregoing clauses (A) through (F),
the Company shall use its best commercially and reasonable efforts to file a
registration statement covering the Registrable Securities so requested to be
registered as soon as practicable after receipt of the request or requests of
the Initiating Holders; provided, however, that if (i) in the good faith
                        --------  -------
judgment of the Board of Directors of the Company, such registration would be
seriously detrimental to the Company and the Board of Directors of the Company
concludes, as a result, that it is essential to defer the filing of such
registration statement at such time, and (ii) 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 of the Company, it would be
seriously detrimental to the Company for such registration statement to be filed
in the near future and that it is, therefore, essential to defer the filing of
such registration statement, then the Company shall have the right to defer such
filing (except as provided in clause (C) above) for a period of not more than
one hundred eighty (180) days after the receipt of the request of the Initiating
Holders, and, provided further, that the Company shall not defer its obligation
in this manner more than twice in any twelve-month period.

          The registration statement filed pursuant to the request of the
Initiating Holders may, subject to the provisions of Sections 3.1(d) and 3.12
hereof, include other securities of the Company, with respect to which
registration rights have been granted, and may include securities of the Company
being sold for the account of the Company.

                       (c)  Underwriting.  The right of any Holder to
                            ------------
registration pursuant to this Section 3.1 shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting (unless otherwise mutually agreed by
a majority in interest of the Initiating Holders and such Holder with respect to
such participation and inclusion) to the extent provided herein. A Holder may
elect to include in such underwriting all or a part of the Registrable
Securities he holds.

                                      -5-
<PAGE>

                       (d)  Procedures.  If the Company shall request inclusion
                            ----------
in any registration pursuant to this Section 3.1 of securities being sold for
its own account, or if other persons shall request inclusion in any registration
pursuant to this Section 3.1, the Initiating Holders shall, on behalf of all
Holders, offer to include such securities in the underwriting and may condition
such offer on their acceptance of the further applicable provisions of this
Section 3. The Company shall (together with all Holders and other persons
proposing to distribute their securities through such underwriting) enter into
an underwriting agreement in customary form with the representative of the
underwriter or underwriters selected for such underwriting by a majority in
interest of the Initiating Holders, which underwriters are reasonably acceptable
to the Company. Notwithstanding any other provision of this Section 3.1, if the
representative of the underwriters advises the Initiating Holders in writing
that marketing factors require a limitation on the number of shares to be
underwritten, the number of shares to be included in the underwriting or
registration shall be allocated as set forth in Section 3.12 hereof. If a person
who has requested inclusion in such registration as provided above does not
agree to the terms of any such underwriting, such person shall be excluded
therefrom by written notice from the Company, the underwriter or the Initiating
Holders. The securities so excluded shall also be withdrawn from registration.
Any Registrable Securities or other securities excluded or withdrawn from such
underwriting shall also be withdrawn from such registration. If shares are so
withdrawn from the registration and if the number of shares to be included in
such registration was previously reduced as a result of marketing factors
pursuant to this Section 3.1(d), then the Company shall offer to all holders who
have retained rights to include securities in the registration the right to
include additional securities in the registration in an aggregate amount equal
to the number of shares so withdrawn, with such shares to be allocated among
such Holders requesting additional inclusion in accordance with Section 3.12.

              3.2      Company Registration.
                       --------------------

                       (a)  Notice to Holders.  If the Company shall determine
                            -----------------
to register any of its securities either for its own account or the account of a
security holder or holders exercising their respective demand registration
rights, other than a registration relating solely to employee benefit plans, or
a registration relating to a corporate reorganization or other transaction on
Form S-4, or a registration on any registration form that does not permit
secondary sales, the Company will:

                            (i)  promptly give to each Holder written notice
thereof; and

                            (ii) use reasonable commercial efforts to include in
such registration (and any related qualification under blue sky laws or other
compliance), except as set forth in Section 3.2(b) below, and in any
underwriting involved therein, all the Registrable Securities specified in a
written request or requests, made by any Holder and received by the Company
within ten (10) days after the written notice from the Company described in
clause (i) above is mailed or delivered by the Company. Such written request may
specify all or a part of a Holder's Registrable Securities.

                       (b)  Underwriting.  If the registration of which the
                            ------------
Company gives notice is for an underwritten public offering, the Company shall
so advise the Holders as a part of the written notice pursuant to Section
3.2(a)(i). In such event, the right of any Holder to registration pursuant to
this Section 3.2 shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting to the extent provided herein.

                                      -6-
<PAGE>

All Holders proposing to distribute their securities through such underwriting
shall (together with the Company and the other holders of securities of the
Company with registration rights to participate therein distributing their
securities through such underwriting) enter into an underwriting agreement in
customary form with the representatives of the underwriter or underwriters
selected by the Company.

          Notwithstanding any other provision of this Section 3.2, if the
representative of the underwriters advised the Company in writing that marketing
factors require a limitation on the number of shares to be underwritten, the
representative may (subject to the limitations set forth below) exclude all
Registrable Securities from, or limit the number of Registrable Securities to be
included in, the registration and underwriting.  The Company shall so advise all
holders of securities requesting registration, and the number of shares of
securities that are entitled to be included in the registration and underwriting
shall be allocated first to the Company for securities being sold for its own
account and thereafter as set forth in Section 3.12.  If any person does not
agree to the terms of any such underwriting, he shall be excluded therefrom by
written notice from the Company or the underwriter.  Any Registrable Securities
or other securities excluded or withdrawn from such underwriting shall be
withdrawn from such registration.

          If shares are so withdrawn from the registration and if the number of
shares of Registrable Securities to be included in such registration was
previously reduced as a result of marketing factors, the Company shall then
offer to all persons who have retained the right to include securities in the
registration the right to include additional securities in the registration in
an aggregate amount equal to the number of shares so withdrawn, with such shares
to be allocated among the persons requesting additional inclusion in accordance
with Section 3.12 hereof.

          3.3      Registration on Form S-3.
                   ------------------------

                   (a)  After its initial public offering, the Company shall use
its best efforts to qualify for registration on Form S-3 or any comparable or
successor form or forms. After the Company has qualified for the use of Form S-
3, in addition to the rights contained in the foregoing provisions of this
Section 3, the Holders of Registrable Securities shall have the right to request
registrations on Form S-3 (such requests shall be in writing and shall state the
number of shares of Registrable Securities to be disposed of and the intended
methods of disposition of such shares by such Holder or Holders); provided,
                                                                  --------
however, that the Company shall not be obligated to effect any such registration
-------
(i) if the Holders, together with the holders of any other securities of the
Company entitled to inclusion in such registration, propose to sell Registrable
Securities and such other securities (if any) on Form S-3 at an aggregate price
to the public of less than $1,000,000, (ii) in the circumstances described in
clauses (A) and (C) of Section 3.1(a), (iii) if the Company shall furnish the
certification described in paragraph 3.1(b) (but subject to the limitations set
forth therein), or (iv) if, in a given twelve-month period, the Company has
effected one (1) such registration in such period.

                   (b)  If a request complying with the requirements of Section
3.3(a) hereof is delivered to the Company, the provisions of Sections 3.1(a)(i)
and (ii) and Section 3.1(b) hereof shall apply to such registration. If the
registration is for an underwritten offering, the provisions of Sections 3.1(c)
and 3.1(d) hereof shall apply to such registration.

                                      -7-

          3.4      Expenses of Registration.
                   ------------------------

                   (a)  All Registration Expenses incurred in connection with
any registration pursuant to Sections 3.1 and 3.2 hereof shall be borne by the
Company; provided, however, that if the Holders bear the Registration Expenses
         --------  -------
for any registration proceeding begun pursuant to Section 3.1 and subsequently
withdrawn by the Holders registering shares therein, such registration
proceeding shall not be counted as a requested registration pursuant to Section
3.1 hereof. Furthermore, in the event that a withdrawal by the Holders is based
upon material adverse information relating to the Company that is different from
the information known or available (upon request from the Company or otherwise)
to the Holders requesting registration at the time of their request for
registration under Section 3.1, such registration shall not be treated as a
counted registration for purposes of Section 3.1 hereof, even though the Holders
do not bear the Registration Expenses for such registration.

                   (b)  All Registration Expenses incurred in any registration
pursuant to Section 3.3 shall be borne by the holders of the securities covered
by such registration pro rata on the basis of the number of securities so
registered on their behalf.

                   (c)  All Selling Expenses relating to securities registered
pursuant to Sections 3.1, 3.2 or 3.3 shall be borne by the holders of such
securities pro rata on the basis of the number of shares of securities so
registered on their behalf, as shall any other expenses in connection with the
registration required to be borne by the Holders of such securities.

          3.5      Registration Procedures.  In the case of each registration
                   -----------------------
effected by the Company pursuant to this Section 3, 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 use its best efforts
to:

                   (a)  Keep such registration effective for a period of one
hundred twenty (120) days or until the Holder or Holders have completed the
distribution described in the registration statement relating thereto, whichever
first occurs; provided, however, that (i) such 120-day period shall be extended
              --------  -------
for a period of time equal to the period the Holder refrains from selling any
securities included in such registration at the request of an underwriter of
Common Stock (or other securities) of the Company; and (ii) in the case of any
registration of Registrable Securities on Form S-3 which are intended to be
offered on a continuous or delayed basis, such 120-day period shall be extended,
if necessary, to keep the registration statement effective until all such
Registrable Securities are sold, however in no event longer than one year from
the effective date of the registration statement and provided that Rule 145,
permits an offering on a continuous or delayed basis, and provided further that
applicable rules under the Securities Act governing the obligation to file a
post-effective amendment permit, in lieu of filing a post-effective amendment
that (I) includes any prospectus required by Section 10(a)(3) of the Securities
Act or (II) reflects facts or events representing a material or fundamental
change in the information set forth in the registration statement, the
incorporation by reference of information required to be included in (I) and
(II) above to be contained in periodic reports filed pursuant to Section 13 or
15(d) of the Exchange Act in the registration statement;

                                      -8-
<PAGE>

                   (b)  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;

                   (c)  Furnish such number of prospectuses and other documents
incident thereto, including any amendment of or supplement to the prospectus, as
a Holder from time to time may reasonably request;

                   (d)  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 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 or incomplete in the light of the
circumstances then existing, and at the request of any such seller, prepare and
furnish to such seller a reasonable number of copies of a supplement to or an
amendment of such prospectus as may be necessary to that, as thereafter
delivered to the purchasers of such shares, 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 there not misleading or
incomplete in the light of the circumstances then existing;

                   (e)  Cause all such Registrable Securities registered
pursuant hereunder to be listed on each securities exchange on which similar
securities issued by the Company are then listed;

                   (f)  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; and

                   (g)  Otherwise use its best efforts to comply with all
applicable rules and regulations of the Commission.

          3.6      Indemnification.
                   ---------------

                   (a)  In the event that Registrable Securities held by any
Holder are included in a registration effected pursuant to this Section 3, the
Company will indemnify such Holder, each of its officers, directors and
partners, legal counsel, and accountants and each person controlling such Holder
within the meaning of Section 15 of the Securities Act, against all expenses,
claims, losses, damages, and liabilities (or actions, proceedings, or
settlements in respect thereof) arising out of or based on any untrue statement
(or alleged untrue statement) of a material fact contained in any registration
statement, prospectus, or other document incident to such registration, or based
on 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 the Company of the Securities Act or any rule or regulation
thereunder applicable to the Company and relating to action or inaction required
of the Company in connection with any such registration, and will reimburse each
such Holder, each of its officers, directors, partners, legal counsel, and
accountants and each person controlling such Holder, for any legal and any other
expenses reasonably incurred in

                                      -9-
<PAGE>

connection with investigating and defending or settling any such claim, loss,
damage, liability, or action; 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
specifically for use in such prospectus or other document. It is agreed that the
indemnity agreement contained in this Section 3.6(a) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld).

                   (b)  Each Holder will, if Registrable Securities held by such
Holder are included in a registration effected pursuant to this Section 3,
indemnify the Company, each of its directors, officers, partners, legal counsel,
and accountants and 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 Section 15 of the Securities Act, each
other such Holder, and each of their officers, directors, and partners, and each
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 registration statement, prospectus, or other document incident to such
registration, 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, and will reimburse the Company and such Holders, directors,
officers, partners, legal counsel, and accountants, persons, underwriter, 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, 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 documents in reliance upon an in conformity with written information
furnished to the Company by such Holder specifically for use therein; provided,
                                                                      --------
however, that the obligations of such Holder hereunder shall not apply to
-------
amounts paid in settlement of any such claims, losses, damages, or liabilities
(or actions in respect thereof) if such settlement is effected without the
consent of such Holder (which consent shall not e unreasonably withheld); and
provided, further, that in no event shall any indemnity under this Section 3.6
--------  -------
exceed the gross proceeds from the offering received by such Holder.

                   (c)  Each party entitled to indemnification under this
Section 3.6 (the "Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of such
claim or any litigation resulting therefrom, provided that counsel for the
                                             --------
Indemnifying Party, who shall conduct the defense of such claim or any
litigation resulting therefrom, shall be approved by the Indemnified Party
(whose approval shall not be unreasonably withheld), and the Indemnified Party
may participate in such defense at such party's expense, and provided further
                                                             -------- -------
that the failure of any Indemnified Party to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under this Section
3, to the extent such failure is not prejudicial. No Indemnifying Party, in the
defense of any such claim or litigation, shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
that does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all liability
in respect to such claim or litigation. Each Indemnified Party shall furnish
such information regarding itself or the claim in questions as an Indemnifying
Party

                                      -10-
<PAGE>

may reasonably request in writing and as shall be reasonably required in
connection with defense of such claim and litigation resulting therefrom.

                   (d)  If the indemnification provided for in this Section 3.6
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 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.

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

          3.7      Information by Holder.  Each Holder of Registrable Securities
                   ---------------------
shall furnish to the Company such information regarding such Holder and the
distribution proposed by such Holder as the Company may reasonably request in
writing and as shall be reasonably required in connection with any registration,
qualification, or compliance referred to in this Section 3.

          3.8      Limitations on Subsequent Registration Rights.  From and
                   ---------------------------------------------
after the date of this Agreement, the Company shall not, without the prior
written consent of a majority in interest of the Holders, enter into any
agreement with any holder or prospective holder of any securities of the Company
giving such holder or prospective holder any registration rights the terms of
which are more favorable than the registration rights granted to the Holders
hereunder.

          3.9      Rule 144 Reporting.  With a view to making available the
                   ------------------
benefits of certain rules and regulations of the Commission that may permit the
sale of the Restricted Securities to the public without registration, the
Company agrees to use its reasonable commercial efforts to:

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

                   (b)  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 at any time after it has become subject to such reporting
requirements;

                   (c)  So long as a Holder owns any Restricted Securities,
furnish to the Holder forthwith upon written request a written statement by the
Company as to its compliance with

                                      -11-
<PAGE>

the reporting requirements of Rule 144 (at any time from and after ninety (90)
days following the effective date of the first registration statement filed by
the Company for an offering of its securities to 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 Holder
may reasonably request in availing itself of any rule or regulation of the
Commission allowing a Holder to sell any such securities without registration.

         3.10      Transfer or Assignment of Registration Rights.  The rights to
                   ---------------------------------------------
cause the Company to register securities granted to a Holder by the Company
under this Section 3 may be transferred or assigned by a Holder with a transfer
of the shares only to a transferee or assignee of not less than 100,000 shares
of Registrable Securities (as presently constituted and subject to subsequent
adjustments for stock splits, stock dividends, reverse stock splits, and the
like), provided that the Company is given written notice at the time of or
within a reasonable time after said transfer or assignment, stating the name and
address of the transferee or assignee and identifying the securities with
respect to which such registration rights are being transferred or assigned,
and, provided further, that the transferee or assignee of such rights assumes in
writing the obligations of such Holder under this Agreement, and agrees to be
bound by all of the terms and conditions of this Agreement.

         3.11      "Market Stand-Off" Agreement.  If requested by the Company
                    ---------------------------
and an underwriter of Common Stock (or other securities) of the Company, an
Investor shall not sell or otherwise transfer or dispose of any Common Stock (or
other securities) of the Company held by such Investor (other than those
included in the registration) during the one hundred eighty (180) day period
following the effective date of a registration statement of the Company filed
under the Securities Act, provided that:

                   (a)  such agreement shall only apply to the first such
registration statement of the Company, including securities to be sold on its
behalf to the public in an underwritten offering; and

                   (b)  all officers and directors of the Company and holders of
at least one percent (1%) of the Company's voting securities are bound by and
have entered into similar agreements.

         The obligations described in this Section 3.11 shall not apply to a
registration relating solely to employee benefit plans on Form S-1 or Form S-8
or similar forms that may be promulgated in the future, or a registration
relating solely to a transaction on Form S-4 or similar forms that may be
promulgated in the future.  The Company may impose stop-transfer instructions
with respect to the shares of Common Stock (or other securities) subject to the
foregoing restriction until the end of such one hundred eighty (180) day period.

         3.12      Allocation of Registration Opportunities.  In any
                   ----------------------------------------
circumstance in which all of the Registrable Securities and other shares of
Common Stock of the Company (including shares of Common Stock issued or issuable
upon conversion of shares of any currently unissued series of Preferred Stock of
the Company) with registration rights (the "Other Shares") requested to be
included in a registration on behalf of the Holders or other selling
stockholders cannot be so included

                                      -12-
<PAGE>

as a result of limitations of the aggregate number of shares of Registrable
Securities and Other Shares that may be so included, the number of shares of
Registrable Securities and Other Shares that may so be included shall be
allocated (1) first to the Holders requesting such registration (where such
registration has been requested by one or more Holders pursuant to Section 3.1
or 3.2), pro rata on the basis of the number of shares of Registrable Securities
held by such Holders, and (2) thereafter to the other selling stockholders
requesting inclusion of Other Shares in such registration, pro rata on the basis
of the number of Other Shares held by such other selling stockholders; provided,
                                                                       --------
however, that such allocation shall not operate to reduce the aggregate number
-------
of Registrable Securities and Other Shares to be included in such registration,
if any Holder or other selling stockholder does not request inclusion of the
maximum number of share of Registrable Securities and Other Shares allocated to
him pursuant to the above-described procedure in which case the remaining
portion of his allocation shall be reallocated among those requesting Holders
and other selling stockholders whose allocations did not satisfy their requests
pro rata on the basis of the number of shares of Registrable Securities and
Other Shares which would be held by such Holders and other selling stockholders,
assuming conversion, and this procedure shall be repeated until all of the
shares of Registrable Securities and Other Share which may be included in the
registration on behalf of the Holders and other selling stockholders have been
so allocated.  The Company shall not limit the number of Registrable Securities
to be included in a registration pursuant to this Agreement in order to include
shares held by stockholders with no registration rights or to include shares of
stock issued to founders of the Company or to employees, officers, directors, or
consultants pursuant to the Company's Stock Option Plan, or in the case of
registrations under Sections 3.1 or 3.3 hereof, in order to include in such
registration securities registered for the Company's own account.

         3.13      Delay of Registration.  No Holder shall have any right to
                   ---------------------
take any action to restrain, enjoin, or otherwise delay any registration as the
result of any controversy that might arise with respect to the interpretation or
implementation of this Section 3.

         3.14      Termination of Registration Rights.  The right of any Holder
                   ----------------------------------
to request registration or inclusion in any registration pursuant to Sections
3.1, 3.2 or 3.3 shall terminate on the earlier of (i) such date after the
closing of the first registered public offering of Common Stock of the Company
as all shares of Registrable Securities held or entitled to be held upon
conversion by such Holder may be sold under Rule 144 during any 90-day period,
or (ii) three (3) years after the closing of the first Company-initiated
registered public offering.

     4.  Covenants of the Company.  The Company hereby covenants and agrees as
         ------------------------
follows:

         4.1      Financial Information.  The Company will furnish the following
