         --------------------

         (a)  At any time after the earlier of (i) the second anniversary of the
date hereof or (ii) the date that is one hundred and eighty (180) days after the
closing of a firm commitment underwriting of any of the Company's securities, a
Majority Interest of the Investors may notify the Company that they intend to
offer or cause to be offered for public sale all or any portion of their
Registrable Securities in the manner specified in such request, provided that in
the case of a request pursuant to clause (ii) such registration may not become
effective prior to the date which is six months after the effective date of the
Company's initial registration statement.  Upon receipt of such request, the
Company shall promptly deliver notice of such request to all Persons holding
Registrable Securities who shall then have thirty (30) days to notify the
Company in writing of their desire to be included in such registration. If the
request for registration contemplates an underwritten public offering, the
Company shall state such in the written notice and in such event the right of
any Person to participate in such registration shall be conditioned upon their
participation in such underwritten public offering and the inclusion of their
Registrable Securities in the underwritten public offering to the extent
provided herein.  The Company will use its reasonable best efforts to
expeditiously effect the registration of all Registrable Securities whose
holders request participation in such registration under the Securities Act and
to qualify such Registrable Securities for sale under any state blue sky law;
provided, however, that the Company shall not be required to effect registration
--------  -------
pursuant to a request under this Section 2 more than three (3) times for the
holders of the Registrable Securities as a group.  Notwithstanding anything to
the contrary contained herein, no request may be made under this Section 2
within one hundred and eighty (180) days after the effective date of a
registration statement filed by the Company covering a Qualified Public
Offering.  The Company may postpone the filing or the effectiveness of any
registration statement pursuant to this Section 2 for a reasonable time period,
provided that such postponements shall not exceed ninety (90) days in the
aggregate during any twelve (12) month period, if (i) the Company has been
advised by legal counsel that such filing or effectiveness would require
disclosure of a material financing, acquisition or other corporate transaction,
and the Board of Directors of the Company determines in good faith that such
disclosure is not in the best interests of the Company and its stockholders or
(ii) the Board of Directors of the Company determines in good faith that there
is a valid business purpose or reason for delaying filing or effectiveness.  A
registration will not count as a requested registration under this Section 2(a)
until the registration statement relating to such registration has been declared
effective by the Commission at the request of the initiating holders; provided,
                                                                      --------
however, that if a majority in interest of the participating holders of
-------
Registrable Securities shall request, in writing, that the Company withdraw a
registration statement which has been filed under this Section 2(a) but not yet
been declared effective, a majority in interest of such holders may thereafter
request the Company to reinstate such Registration Statement, if permitted under
the Securities Act, or to file another registration statement, in accordance
with the procedures set forth herein.

                                       3
<PAGE>

         (b)  Notwithstanding the above, if a requested registration involves an
underwritten public offering and the managing underwriter of such offering
determines in good faith that the number of securities sought to be offered
should be limited due to market conditions, then the number of securities to be
included in such underwritten public offering shall be reduced to a number
deemed satisfactory by such managing underwriter, provided that the shares to be
                                                  --------
excluded shall be determined in the following sequence:  (i) first, securities
held by any other Persons (other than the Investors holding Registrable
Securities) not having registration rights or having contractual, incidental
"piggy back" right to include such securities in the registration statement,
(ii) second, shares sought to be registered by the Company, (iii) third,
Registrable Securities of holders who did not make the original request for
registration, and (iv) fourth, Registrable Securities of holders who requested
such registration pursuant to Section 2(a), it being understood that no shares
shall be registered for the account of the Company or any shareholder other than
the Investors unless all Registrable Securities for which Investors have
requested registration have been registered.  If there is a reduction of the
number of Registrable Securities pursuant to clauses (i), (iii) or (iv), such
reduction shall be made on a pro rata basis (based upon the aggregate number of
shares of Common Stock or Registrable Securities held by the holders in each
tranche and subject to the priorities set forth in the preceding sentence).

         (c)  With respect to a request for registration pursuant to Section
2(a) which is for an underwritten public offering, the managing underwriter
shall be chosen by the Investors holding not less than a Majority Interest of
the Registrable Securities to be sold in such offering, subject to the Company's
consent, which such consent shall not be unreasonably withheld.  The Company may
not cause any other registration of securities for sale for its own account
(other than a registration effected solely to implement an employee benefit plan
or a transaction to which Rule 145 of the Securities Act is applicable) to
become effective within one hundred eighty (180) days following the effective
date of any registration required pursuant to this Section 2 or such lesser
period as may be consented to by the managing underwriter.

     3.  Form S-3.  After the first public offering of its securities registered
         --------
under the Securities Act, the Company shall use its best efforts to qualify and
remain qualified to register securities on Form S-3 (or any successor form)
under the Securities Act.  The holders of Registrable Securities anticipated to
have an aggregate sale price (net of underwriting discounts and commissions, if
any) in excess of $500,000 shall have the right at any time when the Company is
eligible to use Form S-3, on one or more occasions, to request registration on
Form S-3 (or any successor form) for the Registrable Securities held by such
requesting holders.  Such requests shall be in writing and shall state the
number of shares of Registrable Securities to be disposed of and the intended
method of disposition of such shares by such holder or holders.  The Company
shall give notice to all other holders of the Registrable Securities of the
receipt of a request for registration pursuant to this Section 3 and such
holders of Registrable Securities shall then have thirty (30) days to notify the
Company in writing of their desire to participate in the registration.  The
Company may postpone the filing or the effectiveness of any registration
statement pursuant to this Section 3 for a reasonable period of time, provided
that such postponements shall not exceed ninety (90) days in the aggregate
during any twelve (12) month period, if (i) the Company has been advised by
legal counsel that such filing or effectiveness would require disclosure of a
material financing, acquisition or other corporate transaction, and the Board of
Directors of the Company determines in good faith that such disclosure is not in
the

                                       4
<PAGE>

best interests of the Company and its stockholders or (ii) the Board of
Directors determines in good faith that there is a valid business purpose or
reason for delaying filing or effectiveness.

     4.  Piggyback Registration.  If the Company, after the first public
         ----------------------
offering of its securities registered under the Securities Act, proposes to
register any of its Common Stock under the Securities Act for sale to the public
(including pursuant to a demand under Section 2 hereof as provided therein and
except with respect to registration statements on Forms S-4, S-8 or another form
not available for registering the Registrable Securities for sale to the
public), each such time it will give written notice at the applicable address of
record to each holder of Registrable Securities of its intention to do so.  Upon
the written request of any of such holders of the Registrable Securities, given
within thirty (30) days after receipt by such Person of such notice, the Company
will, subject to the limits contained in this Section 4, use its reasonable best
efforts to cause all such Registrable Securities of said requesting holders to
be registered under the Securities Act and qualified for sale under any state
blue sky law, all to the extent required to permit such sale or other
disposition of said Registrable Securities; provided, however, that if the
                                            --------  -------
Company is advised in writing in good faith by any managing underwriter of the
Company's securities being offered in a public offering pursuant to such
registration statement that the amount to be sold by persons other than the
Company (collectively, "Selling Stockholders") is greater than the amount which
can be offered without adversely affecting the offering, the Company may reduce
the amount offered for the accounts of Selling Stockholders (including such
holders of shares of Registrable Securities) to a number deemed satisfactory by
such managing underwriter; and provided further, that the shares to be excluded
                               -------- -------
shall be determined in the following sequence:  (i) first, securities held by
any Persons not having any such contractual, incidental registration rights,
(ii) second, securities held by any Persons having contractual, incidental
registration rights pursuant to an agreement which is not this Agreement, (iii)
third, in a registration requested pursuant to Section 2, all Registrable
Securities other than those held by the initiating Investors, and (iv) fourth,
the Registrable Securities sought to be included by the holders thereof
requesting registration, as determined first by eliminating all Stockholders'
Shares until the Investors as a group have sold and/or are selling shares
(whether pursuant to a registration statement or otherwise) yielding proceeds
(after any underwriting discounts and commissions) equal to or exceeding the
product of (A) the aggregate cash paid by the Investors for their Registrable
Securities acquired prior to the Qualified Public Offering, multiplied by one
hundred and twenty percent (120%), and thereafter on a pro rata basis in
accordance with the holdings of each of the Investors and Stockholders.

     5.  Registration Procedures.  If and whenever the Company is required by
         -----------------------
the provisions of this Agreement to use its reasonable best efforts to effect
the registration of any of its securities under the Securities Act, the Company
will, as expeditiously as possible:

         (a)   use its best efforts diligently to prepare and file with the
Commission a registration statement on the appropriate form under the Securities
Act with respect to such securities, which form shall comply as to form in all
material respects with the requirements of the applicable form and include all
financial statements required by the Commission to be filed therewith, and use
its reasonable best efforts to cause such registration statement to become and
remain effective until completion of the proposed offering (but not for more
than one hundred eighty (180) days);

                                       5
<PAGE>

         (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
until the completion of the offering (but not for more than one hundred eighty
(180) days) and to comply with the provisions of the Securities Act with respect
to the sale or other disposition of all securities covered by such registration
statement whenever the seller or sellers of such securities shall desire to sell
or otherwise dispose of the same, but only to the extent provided in this
Agreement;

         (c)   furnish to each selling holder and the underwriters, if any, such
number of copies of such registration statement, any amendments thereto, any
documents incorporated by reference therein, the prospectus, including a
preliminary prospectus, in conformity with the requirements of the Securities
Act, and such other documents as such selling holder may reasonably request in
order to facilitate the public sale or other disposition of the securities owned
by such selling holder;

         (d)   use its best efforts to register or qualify the securities
covered by such registration statement under and to the extent required by such
other securities or state blue sky laws of such jurisdictions as each selling
holder shall reasonably request, and do any and all other acts and things which
may be necessary under such securities or blue sky laws to enable such selling
holder to consummate the public sale or other disposition in such jurisdictions
of the securities owned by such selling holder, except that the Company shall
not for any such purpose be required to qualify to do business as a foreign
corporation in any jurisdiction wherein it is not so qualified;

         (e)   within a reasonable time before each filing of the registration
statement or prospectus or amendments or supplements thereto with the
Commission, furnish to counsel selected by the holders of Registrable Securities
copies of such documents proposed to be filed, which documents shall be subject
to the reasonable approval of such counsel;

         (f)   promptly notify each selling holder of Registrable Securities,
such selling holders' counsel and any underwriter and (if requested by any such
Person) confirm such notice in writing, of the happening of any event which
makes any statement made in the registration statement or related prospectus
untrue or which requires the making of any changes in such registration
statement or prospectus so that they will not contain any 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 in the light of the circumstances
under which they were made not misleading; and, as promptly as practicable
thereafter, prepare and file with the Commission and furnish a supplement or
amendment to such prospectus so that, as thereafter deliverable to the
purchasers of such Registrable Securities, such prospectus will not contain any
untrue statement of a material fact or omit to state a material fact necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading;

         (g)   use its best efforts to prevent the issuance of any order
suspending the effectiveness of a registration statement, and if one is issued
use its reasonable best efforts to obtain the withdrawal of any order suspending
the effectiveness of a registration statement at the earliest possible moment;

                                       6
<PAGE>

         (h)   if requested by the managing underwriter or underwriters (if
any), any selling holder, or such selling holder's counsel, promptly incorporate
in a prospectus supplement or post-effective amendment such information as such
Person requests to be included therein with respect to the selling holder or the
securities being sold, including, without limitation, with respect to the
securities being sold by such selling holder to such underwriter or
underwriters, the purchase price being paid therefor by such underwriter or
underwriters and with respect to any other terms of an underwritten offering of
the securities to be sold in such offering, and promptly make all required
filings of such prospectus supplement or post-effective amendment;

         (i)   make available to each selling holder, any underwriter
participating in any disposition pursuant to a registration statement, and any
attorney, accountant or other agent or representative retained by any such
selling holder or underwriter (collectively, the "Inspectors"), all financial
and other records, pertinent corporate documents and properties of the Company
(collectively, the "Records"), as shall be reasonably necessary to enable them
to exercise their due diligence responsibility, and cause the Company's
officers, directors and employees to supply all information requested by any
such Inspector in connection with such registration statement subject, in each
case, to such confidentiality agreements as the Company shall reasonably
request;

         (j)   enter into any reasonable underwriting agreement required by the
proposed underwriter(s) for the selling holders, if any, and use its best
efforts to facilitate the public offering of the securities;

         (k)   request that each prospective selling holder be furnished a
signed counterpart, addressed to the prospective selling holder, of (i) an
opinion of counsel for the Company, dated the effective date of the registration
statement, and (ii) if and to the extent permitted by applicable professional
standards, a "comfort" letter signed by the independent public accountants who
have certified the Company's financial statements included in the registration
statement, covering substantially the same matters with respect to the
registration statement (and the prospectus included therein) and (in the case of
the accountants' letter) with respect to events subsequent to the date of the
financial statements, as are customarily covered (at the time of such
registration) in opinions of the Company's counsel and in accountants' letters
delivered to the underwriters in underwritten public offerings of securities;

         (l)   use its best efforts to cause the securities covered by such
registration statement to be listed on the securities exchange or quoted on the
quotation system on which the Common Stock is then listed or quoted (or, if the
Common Stock is not yet listed or quoted, then on such exchange or quotation
system as the selling holders of Registrable Securities and the Company shall
determine);

         (m)   otherwise use its reasonable best efforts to comply with all
applicable rules and regulations of the Commission and make generally available
to its security holders, in each case as soon as practicable, but not later than
90 days after the close of the period covered thereby, an earnings statement of
the Company which will satisfy the provisions of Section 11(a) of the Securities
Act and Rule 158 thereunder (or any comparable successor provisions); and

                                       7
<PAGE>

         (n)   otherwise cooperate with the underwriter(s), the Commission and
other regulatory agencies and take all reasonable actions and execute and
deliver or cause to be executed and delivered all documents reasonably necessary
to effect the registration of any securities under this Agreement.

     6.  Expenses.  All reasonable expenses incurred by the Company and the
         --------
Investors in effecting the registrations provided for in Sections 2 and 3, and
by the Company, the Stockholders and the Investors in effecting the registration
provided for in Section 4, including, without limitation, all registration and
filing fees, printing expenses, fees and disbursements of counsel for the
Company and one counsel for the selling stockholders as a group (selected by a
majority in interest of the holders of Registrable Securities who participate in
the registration), underwriting expenses (other than fees, commissions or
discounts), expenses of any audits incident to or required by any such
registration and expenses of complying with the securities or blue sky laws of
any jurisdictions pursuant to Section 5(d) hereof (all of such expenses referred
to as "Registration Expenses"), shall be paid by the Company.

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

          (a)  The Company shall indemnify and hold harmless the selling holder
of Registrable Securities, each underwriter (as defined in the Securities Act),
and each other Person who participates in the offering of such securities and
each other Person, if any, who controls (within the meaning of the Securities
Act) such seller, underwriter or participating Person (individually and
collectively, the "Indemnified Person") against any losses, claims, damages or
liabilities (collectively, the "liability"), joint or several, to which such
Indemnified Person may become subject under the Securities Act or any other
statute or at common law, insofar as such liability (or action in respect
thereof) arises out of or is based upon (i) any untrue statement or alleged
untrue statement of any material fact contained, on the effective date thereof,
in any registration statement under which such securities were registered under
the Securities Act, any preliminary prospectus or final prospectus contained
therein, or any amendment or supplement thereto, or (ii) 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.  Except as otherwise
provided in Section 7(d), the Company shall reimburse each such Indemnified
Person in connection with investigating or defending any such liability as
expenses in connection with the same are incurred; provided, however, that the
                                                   --------  -------
Company shall not be liable to any Indemnified Person in any such case to the
extent that any such liability arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
such registration statement, preliminary or final prospectus, or amendment or
supplement thereto in reliance upon and in conformity with information furnished
in writing to the Company by such Indemnified Person specifically for use
therein; and provided further, that the Company shall not be required to
             -------- -------
indemnify any Indemnified Person against any liability arising from any untrue
or misleading statement or omission contained in any preliminary prospectus if
such deficiency is corrected in the final prospectus or for any liability which
arises out of the failure of any Indemnified Person to deliver a prospectus as
required by the Securities Act.

          (b)  Each selling holder of any securities included in such
registration being effected shall indemnify and hold harmless each other selling
holder of any securities, the Company, its directors and officers, each
underwriter and each other Person, if any, who controls

                                       8
<PAGE>

the Company or such underwriter (individually and collectively also the
"Indemnified Person"), against any liability, joint or several, to which any
such Indemnified Person may become subject under the Securities Act or any other
statute or at common law, insofar as such liability (or actions in respect
thereof) arises out of or is based upon (i) any untrue statement or alleged
untrue statement of any material fact contained, on the effective date thereof,
in any registration statement under which securities were registered under the
Securities Act at the request of such selling holder, any preliminary prospectus
or final prospectus contained therein, or any amendment or supplement thereto,
or (ii) any omission or alleged omission by such selling holder to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, in the case of (i) and (ii) to the extent,
but only to the extent, that such untrue statement or alleged untrue statement
or omission or alleged omission was made in such registration statement,
preliminary or final prospectus, amendment or supplement thereto in reliance
upon and in conformity with information furnished in writing to the Company by
such selling holder specifically for use therein. Such selling holder shall
reimburse any Indemnified Person for any legal fees incurred in investigating or
defending any such liability; provided, however, that such selling holder's
                              --------  -------
obligationshereunder shall be limited to an amount equal to the proceeds to such
selling holder of the securities sold in any such registration; and provided
further, that no selling holder shall be required to indemnify any Person
against any liability arising from any untrue or misleading statement or
omission contained in any preliminary prospectus if such deficiency is corrected
in the final prospectus or for any liability which arises out of the failure of
any Person to deliver a prospectus as required by the Securities Act.

          (c)  Indemnification similar to that specified in Sections 7(a) and
(b) shall be given by the Company and each selling holder (with such
modifications as may be appropriate) with respect to any required registration
or other qualification of their securities under any federal or state law or
regulation of governmental authority other than the Securities Act.

          (d)  If the indemnification provided for in this Section 7 for any
reason is held by a court of competent jurisdiction to be unavailable to an
indemnified party in respect of any losses, claims, damages, expenses or
liabilities referred to therein, then each indemnifying party under this Section
7, in lieu of indemnifying such indemnified party thereunder, shall contribute
to the amount paid or payable by such indemnified party as a result of such
losses, claims, damages, expenses or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company, the
selling holders and the underwriters from the offering of the Registrable
Securities or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company, the other selling holders and the underwriters in
connection with the statements or omissions which resulted in such losses,
claims, damages, expenses or liabilities, as well as any other relevant
equitable considerations.  The relative benefits received by the Company, the
selling holders and the underwriters shall be deemed to be in the same
respective proportions that the net proceeds from the offering (before deducting
expenses) received by the Company and the selling holders and the underwriting
discount received by the underwriters, in each case as set forth in the table on
the cover page of the applicable prospectus, bear to the aggregate public
offering price of the Registrable Securities.  The relative fault of the
Company, the selling holders and the underwriters shall be determined by
reference to, among other things, whether the untrue or

                                       9
<PAGE>

alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the Company, the
selling holders or the underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

     The Company, the selling holders and the underwriters agree that it would
not be just and equitable if contribution pursuant to this Section 7 were
determined by pro rata or per capita allocation or by any other method of
allocation which does not take account of the equitable considerations referred
to in the immediately preceding paragraph.  In no event, however, shall a
selling holder be required to contribute any amount under this Section 7(d) in
excess of the lesser of (i) that proportion of the total of such losses, claims,
damages or liabilities indemnified against equal to the proportion of the total
Registrable Securities sold under such registration statement which are being
sold by such selling holder or (ii) the proceeds received by such selling holder
from its sale of Registrable Securities under such registration statement.  No
person found guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not found guilty of such fraudulent misrepresentation.

     8.  Market-Standoff.  Each Investor hereby agrees that it shall not, to the
         ---------------
extent requested by the Company or an underwriter of securities of the Company,
sell or otherwise transfer or dispose of any Registrable Securities or other
shares of stock of the Company then owned by such Investors (other than to
donees or partners of the Investor who agree to be similarly bound) for up to
one hundred eighty (180) days following the effective date of a registration
statement of the Company filed under the Securities Act; provided, however,
                                                         --------  -------
that:

         (a) such agreement shall be applicable only to the first such
registration statement of the Company which covers securities to be sold on its
behalf to the public in an underwritten offering but not to Registrable
Securities sold pursuant to such registration statement; and

         (b) all executive officers, directors and two percent (2%)
stockholders of the Company then holding Common Stock of the Company enter into
similar agreements.


In order to enforce the foregoing covenant, the Company shall have the right to
place restrictive legends on the certificates representing the shares subject to
this Section and to impose stop transfer instructions with respect to the
Registrable Securities and such other shares of stock of each Investor (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period. Each Investor further agrees to enter into any
agreement reasonably required by the underwriters to implement the foregoing
within any reasonable timeframe so requested.

     9.  Compliance with Rule 144.  In the event that the Company (i) registers
         ------------------------
a class of securities under Section 12 of the Exchange Act or (ii) shall
commence to file reports under Section 13 or 15(d) of the Exchange Act, the
Company will use its best efforts thereafter to file with the Commission such
information as is required under the Exchange Act for so long as there are
holders of Registrable Securities; and in such event, the Company shall use its
best efforts to take all action as may be required as a condition to the
availability of Rule 144 under the

                                       10
<PAGE>

Securities Act (or any comparable successor rules). The Company shall furnish to
any holder of Registrable Securities upon request a written statement executed
by the Company as to the steps it has taken to comply with the current public
information requirement of Rule 144 (or such comparable successor rules). After
the occurrence of the first underwritten public offering of Common Stock
pursuant to an offering registered under the Securities Act on Form S-1 or Form
SB-1 (or any comparable successor forms), subject to the limitations on
transfers imposed by this Agreement, the Company shall use its reasonable best
efforts to facilitate and expedite transfers of Registrable Securities pursuant
to Rule 144 under the Securities Act, which efforts shall include timely notice
to its transfer agent to expedite such transfers of Registrable Securities.

     10.  Amendments.  The provisions of this Agreement may be amended, and the
          ----------
Company may take any action herein prohibited or omit to perform any act herein
required to be performed by it, only with the written consent of the Company and
Investors then holding a number of Registrable Securities that represents at
least a majority of the total votes to which such Investors are entitled on
account of their Registrable Securities as determined in accordance with the
provisions of the Company's Certificate of Incorporation; provided, however,
                                                          --------  -------
that the piggyback registration rights granted to the Stockholders hereunder may
not be eliminated or materially and adversely changed without the written
consent of the Stockholders holding a majority of the Registrable Securities
then held by the Stockholders.

     11.  New Investors.  Notwithstanding anything herein to the contrary, if
          -------------
pursuant to Section 2.2 of the Series B Agreement, additional parties may
purchase shares of Series B Stock as "New Investors" thereunder, then each such
New Investor shall become a party to this Agreement as an "Investor" hereunder,
without the need of obtaining any consent, approval or signature of any Investor
when such New Investor has both:  (a) purchased shares of Series B Stock under
the Series B Agreement and paid the Company all consideration payable for such
shares and (b) executed one or more counterpart signature pages to this
Agreement as an "Investor", with the Company's consent.

     12.  Prior Rights Agreement Superseded.  Pursuant to Section 9 of the Prior
          ---------------------------------
Rights Agreement, the undersigned parties who are parties to such Prior Rights
Agreement hereby amend and restate the Prior Rights Agreement to read in its
entirety as set forth in this Agreement, all with the intent and effect that the
Prior Rights Agreement shall hereby be terminated and entirely replaced and
superseded by this Agreement.

     13.  Transferability of Registration Rights.  The registration rights set
          --------------------------------------
forth in this Agreement are transferable by any Investor to a transferee or
assignee who acquires at least 100,000 shares of Registrable Securities (subject
to appropriate adjustment for stock splits, stock dividends, reclassifications
and the like), provided that such transfer may otherwise be effected in
accordance with applicable securities laws and provided further that the Company
is given notice of any such assignment or transfer.  Each subsequent holder of
Registrable Securities must consent in writing to be bound by the terms and
conditions of this Agreement in order to acquire the rights granted pursuant to
this Agreement.

     14.  Rights Which May Be Granted to Subsequent Investors.  Other than
          ---------------------------------------------------
permitted pursuant to Sections 11 and 13 hereof, the Company shall not, without
the prior written consent of a Majority Interest of the Investors, (a) allow
purchasers of the Company's securities to

                                       11
<PAGE>

become a party to this Agreement or (b) grant any other registration rights to
any third parties other than subordinate piggyback registration rights.

     15.  Damages.  The Company recognizes and agrees that each holder of
          -------
Registrable Securities will not have an adequate remedy if the Company fails to
comply with the terms and provisions of this Agreement and that damages will not
be readily ascertainable, and the Company expressly agrees that, in the event of
such failure, it shall not oppose an application by any holder of Registrable
Securities or any other Person entitled to the benefits of this Agreement
requiring specific performance of any and all provisions hereof or enjoining the
Company from continuing to commit any such breach of this Agreement.

     16.  Miscellaneous.
