     not to be in the Company's best interest to disclose; or

          (b) prior to receiving the Demand Request, the Board had determined to
     effect an Underwritten Offering and the Company had taken substantial steps
     and is proceeding with reasonable diligence to effect such offering.

<PAGE>

A deferral of the filing of a Registration Statement pursuant to this Section
3.5 shall be lifted, and the requested Registration Statement shall be filed
forthwith, if, (x) in the case of a deferral pursuant to clause (a)(i), the
material non-public information is made public by the Company, (y) in the case
of a deferral pursuant to clause (a)(ii), the significant business opportunity
is disclosed by the Company or is terminated, or (z) in the case of a deferral
pursuant to clause (b), the proposed registration for the Company's account is
abandoned. In order to defer the filing of a registration statement pursuant to
this Section 3.5, the Company shall promptly (but in any event within 10 days),
upon determining to seek such deferral, deliver to each Demand Holder a
certificate signed by an executive officer of the Company stating that the
Company is deferring such filing pursuant to this Section 3.5 and an
approximation of the anticipated delay. Within 20 days after receiving such
certificate, the holders of a majority of the Registrable Securities held by the
Demand Holder and each other Holder and for which registration was previously
requested may withdraw such Demand Request by giving written notice to the
Company.

     incorporated or deemed to be incorporated therein by reference, and file

     of any such selling Holder who unreasonably fails to furnish such
     information within a reasonable time after receiving such request. If the
     Registration Statement refers to any such Holder by name or otherwise as
     the holder of any securities of the Company, then such Holder shall have
     the right to require (if such reference to such Holder by name or otherwise
     is not required by the Securities Act or any similar Federal statute then
     in force) the deletion of the reference to such Holder in any amendment or
     supplement to the Registration Statement filed or prepared subsequent to
     the time that such reference ceases to be required; and

          (q) not file a Registration Statement to which the Holder of a

     Section 8. Indemnification and Contribution
                --------------------------------

     Section 8.1 Indemnification by the Company. The Company shall,
                 ------------------------------
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder and their agents, brokers, investment advisors and employees of each

directors, affiliates, partners and any broker or dealer through whom such
shares may be sold and each Person, if any, who controls (within the meaning of

claims, damages, liabilities, costs (including, without limitation, costs of
preparation and reasonable attorneys' fees) and expenses (collectively,

"Losses"), as incurred, arising out of or relating to any untrue or alleged
 ------
untrue statement of a material fact contained in any Registration Statement, any
Prospectus or any form of Prospectus or in any amendment or supplement thereto
or in any preliminary Prospectus, or arising out of or relating to any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of Prospectus or supplement thereto, in light of the circumstances under which
they were made) not misleading (in the case of any Prospectus or form of
Prospectus or supplement thereto, in light of the circumstances under which they
were made), except to the extent, but only to the extent, that such untrue
statements or omissions are based solely upon information regarding such Holder
furnished in writing to the Company by such Holder expressly for use therein,
which information was reasonably relied on by the Company for use therein or to
the extent that such information relates to such Holder or such Holder's
proposed method of distribution of Registrable Securities and was reviewed and
expressly approved in writing by such Holder expressly for use in any
Registration Statement, such Prospectus or such form of Prospectus or in any
amendment or supplement thereto. The Company shall notify the Holders promptly
of the institution, threat or assertion of any Proceeding of which the Company
is aware in connection with the transactions contemplated by this Agreement.

     Section 8.2 Indemnification by Holders. Each Holder shall, severally and
                 --------------------------
not jointly, indemnify and hold harmless the Company, the directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses (as
determined by a court of competent jurisdiction in a final judgment not subject
to appeal or review) arising solely out of or based solely upon any untrue
statement of a material fact contained in any Registration Statement, any
Prospectus, or any form of Prospectus, or arising solely out of or based solely
upon any untrue statement or omission of a material fact required to be stated
therein or necessary to make the statements therein not misleading to the
extent, but only to the extent, that such untrue statement or omission is
contained or omitted, as the case may be, in any information so furnished in
writing by such Holder to the Company specifically for inclusion in the
Registration Statement or such Prospectus and that such information was
reasonably relied upon by the Company for use in the Registration Statement,
such Prospectus or such form of Prospectus or to the extent that such
information relates to such Holder or such

                                       14
<PAGE>

Holder's proposed method of distribution of Registrable Securities and was
reviewed and expressly approved in writing by such Holder expressly for use in
the Registration Statement, such Prospectus or such form of Prospectus or in any
amendment or supplement thereto. In no event shall the liability of any selling
Holder hereunder be greater in amount than the dollar amount of the net proceeds
received by such Holder upon the sale of the Registrable Securities giving rise
to such indemnification obligation.

     Section 8.3 Conduct of Indemnification Proceedings.
                 --------------------------------------

          (a) If any Proceeding shall be brought or asserted against any Person
     entitled to indemnity hereunder (an "Indemnified Party"), such Indemnified
                                          -----------------
     Party promptly shall notify the Person from whom indemnity is sought (the
     "Indemnifying Party") in writing, and the Indemnifying Party shall assume
     -------------------
     the defense thereof, including the employment of counsel reasonably
     satisfactory to the Indemnified Party and the payment of all fees and
     expenses incurred in connection with defense thereof; provided, that the
     failure of any Indemnified Party to give such notice shall not relieve the
     Indemnifying Party of its obligations or liabilities pursuant to this
     Agreement, except (and only) to the extent that it shall be finally
     determined by a court of competent jurisdiction (which determination is not
     subject to appeal or further review) that such failure shall have
     proximately and materially adversely prejudiced the Indemnifying Party.

          (b) An Indemnified Party shall have the right to employ separate
     counsel in any such Proceeding and to participate in the defense thereof,
     provided, however, the fees and expenses of such counsel shall be at the
     expense of such Indemnified Party or Parties unless: (1) the Indemnifying
     Party has agreed in writing to pay such fees and expenses; or (2) the
     Indemnifying Party shall have failed promptly to assume the defense of such
     Proceeding and to employ counsel reasonably satisfactory to such
     Indemnified Party in any such Proceeding; or (3) the named parties to any
     such Proceeding (including any impleaded parties) include both such
     Indemnified Party and the Indemnifying Party, and such Indemnified Party
     shall have been advised by counsel that a conflict of interest is likely to
     exist if the same counsel were to represent such Indemnified Party and the
     Indemnifying Party (in which case, if such Indemnified Party notifies the
     Indemnifying Party in writing that it elects to employ separate counsel at
     the reasonable expense of the Indemnifying Party, the Indemnifying Party
     shall not have the right to assume the defense thereof and such counsel
     shall be at the reasonable expense of the Indemnifying Party). The
     Indemnifying Party shall not be liable for any settlement of any such
     Proceeding effected without its written consent, which consent shall not be
     unreasonably withheld. No Indemnifying Party shall, without the prior
     written consent of the Indemnified Party, effect any settlement of any
     pending Proceeding in respect of which any Indemnified Party is a party,
     unless such settlement includes an unconditional release of such
     Indemnified Party from all liability on claims that are the subject matter
     of such Proceeding.

          (c) All fees and expenses of the Indemnified Party (including
     reasonable fees and expenses to the extent incurred in connection with
     investigating or preparing to defend

                                       15
<PAGE>

     such Proceeding in a manner not inconsistent with this Section) shall be
     paid to the Indemnified Party, as incurred, within ten (10) Business Days
     of written notice thereof to the Indemnifying Party (regardless of whether
     it is ultimately determined that an Indemnified Party is not entitled to
     indemnification hereunder; provided, that the Indemnifying Party may
     require such Indemnified Party to undertake to reimburse all such fees and
     expenses to the extent it is finally judicially determined that such
     Indemnified Party is not entitled to indemnification hereunder).

     Section 8.4 Contribution.
                 ------------

          (a) If a claim for indemnification under Section 8.1 or 8.2 is
     unavailable to an Indemnified Party because of a failure or refusal of a
     governmental authority to enforce such indemnification in accordance with
     its terms (by reason of public policy or otherwise), then each Indemnifying
     Party, in lieu of indemnifying such Indemnified Party, shall contribute to
     the amount paid or payable by such Indemnified Party as a result of such
     Losses, in such proportion as is appropriate to reflect the relative fault
     of the Indemnifying Party and Indemnified Party in connection with the
     actions, statements or omissions that resulted in such Losses as well as
     any other relevant equitable considerations. The relative fault of such
     Indemnifying Party and Indemnified Party shall be determined by reference
     to, among other things, whether any action in question, including any
     untrue or alleged untrue statement of a material fact or omission or
     alleged omission of a material fact, has been taken or made by, or relates
     to information supplied by, such Indemnifying Party or Indemnified Party,
     and the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such action, statement or omission. The
     amount paid or payable by a party as a result of any Losses shall be deemed
     to include, subject to the limitations set forth herein, any reasonable
     attorneys' or other reasonable fees or expenses incurred by such party in
     connection with any Proceeding to the extent such party would have been
     indemnified for such fees or expenses if the indemnification provided for
     in this Section was available to such party in accordance with its terms.
     In no event shall the liability of any selling Holder hereunder be greater
     in amount than the dollar amount of the net proceeds received by such
     Holder upon the sale of the Registrable Securities giving rise to such
     indemnification obligation.

          (b) The parties hereto agree that it would not be just and equitable
     if contribution pursuant to this Section 8 were determined by pro rata
     allocation or by any other method of allocation that does not take into
     account the equitable considerations referred to in the immediately
     preceding paragraph. Notwithstanding the provisions of this Section 8, no
     Stockholder shall be required to contribute, in the aggregate, any amount
     in excess of the amount by which the proceeds actually received by such
     Stockholder from the sale of the Registrable Securities subject to the
     Proceeding exceeds the amount of any damages that such Stockholder has
     otherwise been required to pay by reason of such untrue or alleged untrue
     statement or omission or alleged omission. No Person 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 guilty
     of such fraudulent misrepresentation.

                                       16
<PAGE>

          (c) The indemnity and contribution agreements contained in this
     Section 8 are in addition to any liability that the Indemnifying Parties
     may have to the Indemnified Parties.

     Section 8.5 Rule 144. Following the IPO, the Company covenants that:
                 --------

          (a) it will file the reports required to be filed by the Company under
     the Securities Act and the Exchange Act, so as to enable the Holders to
     sell Registrable Securities pursuant to Rule 144 under the Securities Act;

          (b) it shall cooperate with any Holder in connection with any sale,
     transfer or other disposition by such Holder of any Registrable Securities
     pursuant to Rule 144 under the Securities Act;

          (c) it will take such action as any Holder may reasonably request, all
     to the extent required from time to time to enable such Holder to sell its
     Common Stock without registration under the Securities Act within the
     limitation of the exemptions provided by Rule 144 promulgated under the
     Securities Act, including providing any legal opinions; and

          (d) upon the request of any Holder, it shall deliver to such Holder a
     written certification of a duly authorized officer as to whether it has
     complied with such requirements.

     Section 9. Term of Registration Rights.
                ---------------------------

in writing hereafter, in the same manner, by such person.

     Section 10.3 Remedies. In the event of a breach by the Company or by a
                  --------
Holder of any of their obligations under this Agreement, each Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law and under this Agreement, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary damages would not provide adequate
compensation for any losses incurred by reason of a breach by it of any of the
provisions of this Agreement and hereby further agrees that, in the event of any
action for specific performance in respect of such breach, it shall waive the
defense that a remedy at law would be adequate.

     Section 10.4 No Inconsistent Agreements. Neither the Company nor any of its
                  --------------------------
Subsidiaries has, as of the date hereof, nor shall the Company or any of its
Subsidiaries, on or after the date of this Agreement, enter into any agreement
with respect to its securities that is inconsistent with the rights granted to
the Holders in this Agreement or otherwise conflicts with the provisions hereof.
Neither the Company nor any of its Subsidiaries has previously entered into any
agreement granting any registration rights with respect to any of its securities
to any Person. Without limiting the generality of the foregoing, the Company
shall not grant to any Person the right to request the Company to register any
securities of the Company under the Securities Act unless the rights so granted
are subject in all respects to the prior rights in full of the Holders, and are
not otherwise in conflict or inconsistent with the provisions of this Agreement.

     Section 10.5 Amendments and Waivers. No provision of this Agreement may be
                  ----------------------
waived or amended except in a written instrument signed, in the case of an
amendment, by the Company and the Holders; or, in the case of a waiver, by the
party against whom enforcement of any such waiver is sought. No waiver of any
default with respect to any provision, condition or requirement of this
Agreement shall be deemed to be a continuing waiver in the future or a waiver of
any other provision, condition or requirement hereof, nor shall any delay or
omission of either party to exercise any right hereunder in any manner impair
the exercise of any such right accruing to it thereafter. Notwithstanding the
foregoing, no such amendment shall be effective to the extent that it applies to
less than all of the Holders. The Company shall not offer or pay any
consideration to a Holder for consenting to such an amendment or waiver unless
the same consideration is offered to each Holder and the same consideration is
paid to each Holder which consents to such amendment or waiver.

     Section 10.6 Successors and Assigns. This Agreement shall inure to the
                  ----------------------
benefit of and be binding upon the successors and permitted assigns of each of
the parties. The rights of each Holder hereunder, including the right to have
the Company register for resale Registrable Securities in accordance with the
terms of this Agreement, shall be automatically assignable by each Holder
together with the Registrable Security, or the securities into which such
Registrable Securities are convertible or exchangeable into, to which such
rights relate if: (a) the Holder agrees in writing with the transferee or
assignee to assign such rights, and a copy of such agreement is furnished to the
Company within a reasonable time after such assignment, (b) the Company is,
within a reasonable time after such transfer or assignment, furnished with
written notice of (i) the name and address of such transferee or assignee, and
(ii) the securities with respect to which such registration rights are being
transferred or assigned, (c) following such transfer or assignment the further
disposition of such securities by the transferee or assignee is restricted under
the Securities Act and applicable state securities laws, (d) the transferee or
assignee agrees in writing with the Company to be bound by all of the provisions
of this Agreement, and (e) such transfer shall have been made in accordance with
the applicable requirements of any agreement applicable to the transfer of such
shares, including, without limitation, the Stockholders' Agreement. The rights
to assignment shall apply to the Holders (and to subsequent) successors and
assigns.

     Section 10.7 No Third-Party Beneficiaries. This Agreement is intended for
                  ----------------------------
the benefit of the parties hereto and their respective successors and permitted
assigns and is not for the benefit of, nor may any provision hereof be enforced
by, any other person.

     Section 10.8 Cumulative Remedies. The remedies provided herein are
                  -------------------
cumulative and not exclusive of any remedies provided by law.

     Section 10.9 Severability. If any term, provision, covenant or restriction
                  ------------
of this Agreement is held by a court of competent jurisdiction to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their reasonable efforts to find and employ an alternative
means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and
declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of
such that may be hereafter declared invalid, illegal, void or unenforceable.
