                    -------------------------------
days after the IPO Effectiveness Date, the holders of at least 15% of the then
outstanding Registrable Securities that have an aggregate offering price of at
least $10,000,000 (the "Initiating Holders"), may make a written request to the
                        ------------------
Company to register, and the Company shall register, under the Securities Act
(other than pursuant to a Registration Statement on Form S-4 or S-8 or any
successor thereto) (a "Demand Registration"), the number of Registrable
                       -------------------
Securities stated in such request; provided, however, that the Company shall not
                                   --------  -------
be obligated to effect more than four such Demand Registrations on a Securities
Act registration form other than Form S-3 (or any successor form thereto). If at
the time of any request to register Registrable Securities pursuant to this
Section 3(a), the Company is engaged in, or has fixed plans to engage in within
sixty (60) days of the time of such request, a registered public offering or is
engaged in any other activity which, in the good faith determination of the
Board of Directors of the Company, would be adversely affected by the Demand
Registration to the material detriment of the Company, then the Company may at
its option direct that such request be delayed for a reasonable period not in
excess of sixty (60) days from the effective date of such offering or the date
of completion of such other activity, as the case may be, such right to delay a
request to be exercised by the Company not more than two non-consecutive times
in any twelve (12) month period; provided, that two such 60-day periods may be
                                 --------
consecutive in the event that (i) the Company would be required to disclose in
the prospectus contained in the Registration Statement information not otherwise
publicly disclosed, and (ii) there is a likelihood, in the reasonable judgment
of the Board of Directors of the Company, that such disclosure, or any other
action to be taken in connection with such prospectus, would materially and
adversely affect or interfere with any financing, acquisition, merger or similar
transaction involving the Company.  Each request for a Demand Registration by
the Initiating Holders shall state the amount of the Registrable Securities
proposed to be sold and the intended method of disposition thereof.

               (b)  Incidental or "Piggy-Back" Rights with Respect to a Demand
                    ----------------------------------------------------------
Registration.  Each of the Designated Holders (other than Initiating Holders
------------
which have requested a registration under Section 3(a)) may offer its or his
Registrable Securities under any Demand Registration pursuant to this Section
3(b).  Within ten (10) days after the receipt of a request for a Demand
Registration from an Initiating

                                                                               7


Holder, the Company shall (i) give written notice thereof to all of the
Designated Holders (other than Initiating Holders which have requested a
registration under Section 3(a)) and (ii) subject to Section 3(e), include in
such registration all of the Registrable Securities held by such Designated
Holders from whom the Company has received a written request for inclusion
therein within ten (10) days of the receipt by such Designated Holders of such
written notice referred to in clause (i) above. Each such request by such
Designated Holders shall specify the number of Registrable Securities proposed
to be registered. The failure of any Designated Holder to respond within such
10-day period referred to in clause (ii) above shall be deemed to be a waiver of
such Designated Holder's rights under this Section 3 with respect to such Demand
Registration, provided that any Designated Holder may waive its rights under
              --------
this Section 3 prior to the expiration of such 10-day period by giving written
notice to the Company, with a copy to the Initiating Holders. If a Designated
Holder sends the Company a written request for inclusion of part or all of such
Designated Holder's Registrable Securities in a registration, such Designated
Holder shall not be entitled to withdraw or revoke such request without the
prior written consent of the Company in its sole discretion unless, as a result
of facts or circumstances arising after the date on which such request was made
relating to the Company or to market conditions, such Designated Holder
reasonably determines that participation in such registration would have a
material adverse effect on such Designated Holder.

               (c)  Effective Demand Registration.  The Company shall use its
                    -----------------------------
best efforts to cause any such Demand Registration to become and remain
effective not later than sixty (60) days after it receives a request under
Section 3(a) hereof. A registration shall not constitute a Demand Registration
until it has become effective and remains continuously effective for the lesser
of (i) the period during which all Registrable Securities registered in the
Demand Registration are sold and (ii) 90 days; provided, however, that a
                                               --------  -------
registration shall not constitute a Demand Registration if (x) after such Demand
Registration has become effective, such registration or the related offer, sale
or distribution of Registrable Securities thereunder is interfered with by any
stop order, injunction or other order or requirement of the Commission or other
governmental agency or court for any reason not attributable to the Initiating
Holders and such interference is not thereafter eliminated or (y) the conditions
specified in the underwriting agreement, if any, entered into in connection with
such Demand Registration are not satisfied or waived, other than by reason of a
failure by the Initiating Holder.

               (d)  Expenses.  The Company shall pay all Registration
                    --------
Expenses in connection with a Demand Registration (other than underwriting
discounts and commissions and brokerage commissions), including the reasonable
fees and expenses of one counsel selected by the Designated Holders holding a
majority of the Registrable Securities being registered in such registration
("Holders Counsel") in connection therewith (not to exceed $15,000), whether or
  ---------------
not such Demand Registration becomes effective.

               (e)  Underwriting Procedures.  If the Company or the Initiating
                    -----------------------
Holders holding a majority of the Registrable Securities held by all of the
Initiating Holders so elect, the Company shall use its reasonable best efforts
to cause a Demand Registration to be in the form of a firm commitment
underwritten offering and the managing underwriter or underwriters selected for
such offering shall be the Approved Underwriter selected in accordance with
Section 3(f).  In connection with any Demand Registration under this Section 3
involving an underwritten offering, none of the Registrable Securities held by
any Designated Holder making a request for inclusion of such Registrable
Securities pursuant to Section 3(b) hereof shall be included in such
underwritten offering unless such Designated Holder accepts the terms of the
offering as agreed upon by the Company, the Initiating Holders and the Approved
Underwriter, and then only in such quantity as will not, in the opinion of the
Approved Underwriter, be detrimental to of such offering by the Initiating
Holders.  If the Approved Underwriter advises the Company that the aggregate
amount of such Registrable Securities requested to be included in such offering
is sufficiently large to be detrimental to such offering, then the Company shall
include in such registration only the aggregate amount of Registrable Securities
that the Approved Underwriter believes may be sold without any such detrimental
effect and shall reduce the amount of Registrable Securities to be included in
such registration, first as to the Company, second as to the Designated Holders
                   -----                    ------
(who are not Initiating Holders and who requested to participate in such
registration pursuant to Section 3(b) hereof) as a group, if any, and third as
                                                                      -----
to the Initiating Holders as a group, pro rata within each group based on the
number of Registrable Securities owned by each such Designated Holder or
Initiating Holder, as the case may be.

               (f)  Selection of Underwriters.  If any Demand Registration or
                    -------------------------
S-3 Registration, as the case may be, of Registrable Securities is in the form
of an underwritten offering, the Company shall use its reasonable best efforts
to select and obtain an investment banking firm of national reputation to act as
the managing underwriter of the offering (the "Approved Underwriter"); provided,
                                               --------------------    --------
however, that the Approved Underwriter shall, in any case, also be approved by
-------
the Initiating Holders or S-3 Initiating Holders, as the case may be, such
approval not to be unreasonably withheld.

          4.   Incidental or "Piggy-Back" Registration.

                                                                               9

          (a)  Request for Incidental Registration.  At any time after the IPO
               -----------------------------------
Effectiveness Date, if the Company proposes to file a Registration Statement
under the Securities Act with respect to an offering by the Company for its own
account (other than a Registration Statement on Form S-4 or S-8 or any successor
thereto or pursuant to Rule 415 under the Securities Act) or for the account of
any stockholder of the Company other than the Designated Holders, then the
Company shall give written notice of such proposed filing to each of the
Designated Holders at least twenty (20) days before the anticipated filing date,
and such notice shall describe the proposed registration and distribution and
offer such Designated Holders the opportunity to register the number of
Registrable Securities as each such Designated Holder may request (an
"Incidental Registration").  The Company shall use its reasonable best efforts
 -----------------------
to cause the managing underwriter or underwriters in the case of a proposed
underwritten offering (the "Company Underwriter") to permit each of the
Designated Holders who have requested in writing to participate in the
Incidental Registration to include its or his Registrable Securities in such
offering on the same terms and conditions as the securities of the Company or
the account of such other stockholder, as the case may be, included therein.  In
connection with any Incidental Registration under this Section 4(a) involving an
underwritten offering, the Company shall not be required to include any
Registrable Securities in such underwritten offering unless the Designated
Holders thereof accept the terms of the underwritten offering as agreed upon
between the Company, such other stockholders, if any, and the Company
Underwriter, and then only in such quantity as the Company Underwriter believes
will not be detrimental to the success of the offering by the Company and such
other stockholders.  If the Company Underwriter determines that the registration
of all or part of the Registrable Securities which the Designated Holders have
requested to be included would be detrimental to such offering, then the Company
shall be required to include in such Incidental Registration, to the extent of
the amount that the Company Underwriter believes may be sold without causing
such detrimental effect, (i) if such offering is by the Company for its own
account, then first, all of the securities to be offered for the account of the
              -----
Company; second, the Registrable Securities to be offered for the account of the
         ------
Designated Holders pursuant to this Section 4, pro rata based on the number of
Registrable Securities owned by each such Designated Holder; and third, any
                                                                 -----
other securities requested to be included in such offering; or (ii) if such
offering is for the account of any stockholder of the Company other than the
Designated Holders, then first, all of the securities to be offered for the
                         -----
account of such stockholder; and second, the Registrable Securities to be
                                 ------
offered for the account of the Designated Holders pursuant to this Section 4,
pro rata based on the number of Registrable Securities owned by each such
Designated Holder, and any securities to be offered for the account of the
Company, ratably.

          (b)  Expenses.  The Company shall bear all Registration Expenses
               --------
(other than underwriting discounts and commissions and brokerage commissions),
including the reasonable fees and expenses of Holders' Counsel in connection
therewith (not to exceed $15,000) in connection with any Incidental

                                                                              10

Registration pursuant to this Section 4, whether or not such Incidental
Registration becomes effective.

          5.   Form S-3 Registration.
               ---------------------

               (a)  Request for a Form S-3 Registration.  Upon the Company
                    -----------------------------------
becoming eligible for use of Form S-3 (or any successor form thereto) under the
Securities Act in connection with a public offering of its securities, in the
event that the Company shall receive from one or more of the Stockholders (the
"S-3 Initiating Holders"), a written request that the Company register, under
 ----------------------
the Securities Act on Form S-3 (or any successor form then in effect) (an "S-3
                                                                           ---
Registration"), all or a portion of the Registrable Securities owned by such S-3
------------
Initiating Holders, the Company shall give written notice of such request to all
of the Designated Holders (other than S-3 Initiating Holders which have
requested an S-3 Registration under this Section 5(a)) at least thirty (30) days
before the anticipated filing date of such Form S-3, and such notice shall
describe the proposed registration and offer such Designated Holders the
opportunity to register the number of Registrable Securities as each such
Designated Holder may request in writing to the Company, given within fifteen
(15) days after their receipt from the Company of the written notice of such
registration.  With respect to each S-3 Registration, the Company shall, subject
to Section 5(b), (i) include in such offering the Registrable Securities of the
S-3 Initiating Holders, and (ii) use its reasonable best efforts to (x) cause
such registration pursuant to this Section 5(a) to become and remain effective
as soon as practicable, but in any event not later than forty-five (45) days
after it receives a request therefor and (y) include in such offering the
Registrable Securities of the Designated Holders (other than S-3 Initiating
Holders which have requested an S-3 Registration under this Section 5(a)) who
have requested in writing to participate in such registration on the same terms
and conditions as the Registrable Securities of the S-3 Initiating Holders
included therein.  Each S-3 Registration shall remain continuously effective for
the lesser of (A) the period during which all Registrable Securities registered
in such registration are sold, and (B) 90 days.

               (b)  Form S-3 Underwriting Procedures.  If the Company or the S-3
                    --------------------------------
Initiating Holders holding a majority of the Registrable Securities held by all
of the S-3 Initiating Holders so elect, the Company shall use its reasonable
best efforts to cause such S-3 Registration pursuant to this Section 5 to be in
the form of a firm commitment underwritten offering and the managing underwriter
or underwriters selected for such offering shall be the Approved Underwriter
selected in accordance with Section 3(f).  In connection with any S-3
Registration under Section 5(a) involving an underwritten offering, the Company
shall not be required to include any Registrable Securities in such underwritten
offering unless the Designated Holders thereof accept the terms of the
underwritten offering as agreed upon between the Company, the Approved
Underwriter and the S-3 Initiating Holders, and then only in such quantity as
such underwriter believes will not be detrimental to of such offering by the S-3
<PAGE>

                                                                              11

Initiating Holders. If the Approved Underwriter believes that the registration
of all or part of the Registrable Securities which the S-3 Initiating Holders
and the other Designated Holders have requested to be included would be
detrimental to the success of such public offering, then the Company shall be
required to include in the underwritten offering, to the extent of the amount
that the Approved Underwriter believes may be sold without causing such
detrimental effect, first, all of the Registrable Securities to be offered for
                    -----
the account of the S-3 Initiating Holders, pro rata based on the number of
Registrable Securities owned by such S-3 Initiating Holders; second, the
                                                             ------
Registrable Securities to be offered for the account of the other Designated
Holders who requested inclusion of their Registrable Securities pursuant to
Section 5(a), pro rata based on the number of Registrable Securities owned by
such Designated Holders; and third, any other securities requested to be
                             -----
included in such offering.

               (c)  Limitations on Form S-3 Registrations. If at the time of any
                    -------------------------------------
request to register Registrable Securities pursuant to Section 5(a), the Company
is engaged in, or has fixed plans to engage in within sixty (60) days of the
time of such request, a registered public offering or is engaged in any other
activity which, in the good faith determination of the Board of Directors of the
Company, would be adversely affected by the requested S-3 Registration to the
material detriment of the Company, then the Company may at its option direct
that such request be delayed for a reasonable period not in excess of sixty (60)
days from the effective date of such offering, such right to delay a request to
be exercised by the Company not more than two non-consecutive times in any
twelve (12) month period; provided, that two such 60-day periods may be
                          --------
consecutive in the event that (i) the Company would be required to disclose in
the prospectus relating to such S-3 Registration information not otherwise
publicly disclosed, and (ii) there is a likelihood, in the reasonable judgment
of the Board of Directors of the Company, that such disclosure, or any other
action to be taken in connection with such S-3 Registration would materially and
adversely affect or interfere with any financing, acquisition, merger or similar
transaction involving the Company.  In addition, the Company shall not be
required to effect any registration pursuant to Section 5(a), (i) within 180
days after the pricing date of the Initial Public Offering, (ii) if within the
twelve (12) month period preceding the date of such request, the Company has
effected two (2) registrations on Form S-3 pursuant to Section 5(a), (iii) if
Form S-3 is not available for such offering by the S-3 Initiating Holders or
(iv) if the S-3 Initiating Holders, together with the Designated Holders (other
than S-3 Initiating Holders which have requested an S-3 Registration under
Section 5(a)) registering Registrable Securities in such registration, propose
to sell their Registrable Securities at an aggregate price (calculated based
upon the Market Price of the Registrable Securities on the date of filing of the
Form S-3 with respect to such Registrable Securities) to the public of less than
$1,000,000.

               (d)  Expenses.  The Company shall bear all Registration Expenses

                    ----------------------
Designated Holder pursuant to this Section 5 shall be deemed a Demand
Registration pursuant to Section 3.

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

               (a)  Restrictions on Public Sale by Designated Holders.  To the
                    -------------------------------------------------
extent requested (i) by the Company, the Initiating Holders or the S-3
Initiating Holders, as the case may be, in the case of a non-underwritten public
offering and (ii) by the Approved Underwriter or the Company Underwriter, as the
case may be, in the case of an underwritten public offering, each Designated
Holder of Registrable Securities agrees (x) not to directly or indirectly sell,
offer to sell, contract to sell (including, without limitation, any short sale),
grant any option to purchase or otherwise transfer or dispose of (other than to
donees who agree to be similarly bound) any Registrable Securities or of any

Securities, including a sale pursuant to Rule 144 under the Securities Act, and
(y) not to make any request for a Demand Registration or S-3 Registration under
this Agreement, during the ten (10) days prior to, and during the ninety (90)

such shorter period, if any, mutually agreed upon by such Designated Holder, the
Company and the requesting party beginning on the effective date of such
Registration Statement (except as part of such registration).

               (b)  Restrictions on Public Sale by the Company.  To the extent

underwritten public offering and (ii) by the Approved Underwriter or the Company
Underwriter, as the case may be, in the case of an underwritten public offering
the Company agrees not to effect any public sale or distribution of any of its
securities, or any securities convertible into or exchangeable or exercisable
for such securities (except pursuant to registrations on Form S-4 or S-8 or any
successor thereto), during the ten (10) days prior to, and during the period
beginning on the effective date of any Registration Statement in which the
Designated Holders of Registrable Securities are participating and ending on the
earlier of (i) the date on which all Registrable Securities registered on such

all Registrable Securities covered by such Registration Statement have been
sold, and comply with the provisions of the Securities Act with respect to the

including all exhibits thereto), and the prospectus included in such
Registration Statement (including each preliminary prospectus) as each such
seller may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by such seller;

               (iv)   register or qualify such Registrable Securities under such
other securities or "blue sky" laws of such jurisdictions as any seller of

light of the circumstances under which they were made, not misleading and the
