to the filing of the Registration Statement or any related Prospectus or any
amendment or supplement thereto (including any document that would be
incorporated therein by reference), the Company shall furnish to the Holders
copies of all such documents proposed to be filed, which documents (other than
those incorporated by reference) will be subject to the review of such Holders.

        (b) (i) Prepare and file with the Commission such amendments, including
post-effective amendments, to the Registration Statement as may be necessary to
keep the Registration Statement continuously effective as to the applicable
Registrable Securities for the Effectiveness Period; (ii) cause the related
Prospectus to be amended or supplemented by any required Prospectus supplement,
and as so supplemented or amended to be filed with the Commission; (iii) respond
as promptly as practicable to any comments received from the Commission with
respect to the Registration Statement or any amendment thereto and as promptly
as practicable provide the Holders true and complete copies of all
correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

        (c) Notify the Holders of Registrable Securities to be sold as promptly
as practicable (i)(A) when a Prospectus or any Prospectus supplement or post-
effective amendment to the Registration Statement is proposed to be filed; (B)
when the Commission notifies the Company whether there will be a "review" of
such Registration Statement and whenever the Commission comments in writing on
such Registration Statement and (C) with respect to the Registration Statement
or any post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority

the suspension of the qualification or exemption from qualification of any of

threatening of any Proceeding for such purpose; and (v) of the occurrence of any
event that makes any statement made in the Registration Statement or Prospectus
or any document incorporated or deemed to be incorporated therein by reference
untrue in any material respect or that requires any revisions to the
Registration Statement, Prospectus or other documents so that, in the case of
the Registration Statement or the Prospectus, as the case may be, it 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.

        (d) Use its reasonable best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of, (i) any order suspending the effectiveness of
the Registration Statement or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

                                      -4-
<PAGE>

        (e) Promptly deliver to each Holder, without charge, as many copies of
the Registration Statement, Prospectus or Prospectuses (including each form of
prospectus) and each amendment or supplement thereto as such Persons may
reasonably request.

        (f) Prior to any public offering of Registrable Securities, use its
reasonable best efforts to register or qualify or cooperate with the selling
Holders in connection with the registration or qualification (or exemption from
such registration or qualification) of such Registrable Securities for offer and
sale under the securities or Blue Sky laws of such jurisdictions within the
United States as any Holder requests in writing, to keep each such registration
or qualification (or exemption therefrom) effective during the Effectiveness
Period and to do any and all other acts or things necessary to enable the
disposition in such jurisdictions of the Registrable Securities covered by a
Registration Statement; provided, however, that the Company shall not be
                        --------  -------
required to qualify generally to do business in any jurisdiction where it
is not then so qualified or to take any action that would subject it to general
service of process in any such jurisdiction where it is not then so subject or
subject the Company to any material tax in any such jurisdiction where it is not
then so subject.

        (g) Cooperate with the Holders to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold pursuant
to a Registration Statement, which certificates shall be free of all restrictive
legends.

        (h) Upon the occurrence of any event contemplated by Section 3(c)(v), as
promptly as practicable, prepare a supplement or amendment, including a post-
effective amendment, to the Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as
thereafter delivered, neither the Registration Statement nor such Prospectus
will contain 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 therein,
in the light of the circumstances under which they were made, not misleading.

        (i) Use its reasonable best efforts to cause all Registrable Securities
relating to such Registration Statement to be listed on the Nasdaq and any other
securities exchange, quotation system, market or over-the-counter bulletin
board, if any, on which similar securities issued by the Company are then
listed.

        (j) Comply in all material respects with all applicable rules and
regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 not later than forty-five (45) days after the end of
any 12-month period (or ninety (90) days after the end of any 12-month period if
such period is a fiscal year) commencing on the first day of the first fiscal
quarter of the Company after the effective date of the Registration Statement,
which statement shall conform to the requirements of Rule 158.

        (k) Require each selling Holder to furnish to the Company information
regarding such Holder and the distribution of such Registrable Securities as is
required by law to be disclosed in the Registration Statement, and the Company
may exclude from such registration the Registrable Securities of any such Holder
who fails to furnish such information within a

                                      -5-
<PAGE>

reasonable time prior to the filing of each Registration Statement, supplemented
Prospectus and/or amended Registration Statement.

          If the Registration Statement refers to any 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.

          Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(e) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(c), (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to them in connection with sales of Registrable Securities pursuant
to the Registration Statement, and (iii) if any Registration Statement or
Prospectus refers to any Holder by name or otherwise as the Holder of any
securities of the Company, then such Holder shall promptly notify the Company of
any fact of which the Holder becomes aware and the happening of any event which
relates to the Holder or distribution of such securities owned by such Holder
which results in the Registration Statement or the Prospectus included in such
Registration Statement containing an untrue statement of material fact or
omitting to state a material fact required to be stated therein or necessary to
make the statements therein not misleading and shall provide to the Company such
information as shall be necessary to enable the Company to prepare a supplement
or post-effective Amendment to such Registration Statement or Prospectus or any
document incorporated therein by reference or file any other document required
so that the Registration Statement or Prospectus will not contain an untrue
statement of material fact or omit to state a material fact required to be
stated therein.

          Each Holder agrees by its acquisition of such Registrable Securities
that, upon receipt of a notice from the Company of the occurrence of any event
of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv) or 3(c)(v), such
Holder will forthwith discontinue disposition of such Registrable Securities
under the Registration Statement until such Holder's receipt of the copies of
the supplemented Prospectus and/or amended Registration Statement contemplated
by Section 3(h), or until it is advised in writing (the "Advice") by the Company
                                                         ------
that the use of the applicable Prospectus may be resumed, and, in either case,
has received copies of any additional or supplemental filings that are
incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

        (l) If (i) there is material non-public information regarding the
Company which the Company's Board of Directors (the "Board") reasonably
                                                     -----
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably determines not to be in the Company's
best interest to disclose and which the Company would be

                                      -6-
<PAGE>

required to disclose under the Registration Statement, then the Company may
suspend effectiveness of a registration statement and suspend the sale of
Registrable Securities under a Registration Statement for a period that the
Board, in its sole discretion, determines to be reasonable under the
circumstances (a "Blackout Period").
                  ---------------

        (m) Notwithstanding anything to the contrary contained in this
Agreement, (i) the Registration Statement shall register for resale only the
Registrable Securities and those securities listed on Schedule 3.2 to the
Purchase Agreement, and (ii) the Company shall not be permitted to file a
registration statement for a period ending 120 days from the date hereof;
provided, however, that the Company may file a registration statement for up to

Securities shall be borne by the Company, other than fees and expenses of any
counsel retained by the Holders in connection with the transactions contemplated

Act or Section 20 of the Exchange Act) and the officers, directors, agents and
employees of each such controlling Person, and the respective successors,
assigns, estate and personal representatives of each of the foregoing, to the

                                      -7-
<PAGE>

fullest extent permitted by applicable law, from and against any and all claims,
losses, damages, liabilities, penalties, judgments, costs (including, without
limitation, costs of investigation) and expenses (including, without limitation,
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 the 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 the light of the circumstances under which they were
made) not misleading, except to the extent, but only to the extent, that such
untrue statements or omissions are based 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. 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. Such indemnity shall survive the
transfer of the Registrable Securities by the Holders.

        (b) Indemnification by Holders. Each Holder shall, severally and not
            --------------------------
jointly, indemnify and hold harmless the Company, the directors, officers,

directors, officers, agents or employees of such controlling Persons, and the
respective successors, assigns, estate and personal representatives of each of
the foregoing, to the fullest extent permitted by applicable law, from and
against all Losses, as incurred, arising solely out of or based solely upon any
untrue statement of a material fact contained in the Registration Statement, any
Prospectus, or any form of prospectus, or arising solely out of or based solely
upon any 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 the light of the circumstances under which
they were made) not misleading, to the extent, but only to the extent, that such
untrue statement or omission is contained in or omitted from 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. Notwithstanding anything to the
contrary contained herein, the Holder shall be liable under this Section 5(b)
for only that amount as does not exceed the net proceeds to such Holder as a
result of the sale of Registrable Securities pursuant to such Registration
Statement.

        (c) Conduct of Indemnification Proceedings. 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

                                      -8-
<PAGE>

subject to appeal or further review) that such failure shall have proximately
and materially adversely prejudiced the Indemnifying Party.

          An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but 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
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 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.

          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 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.

        (d) Contribution. If a claim for indemnification under Section 5(a) or
5(b) 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, severally and not
jointly, 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
in Section

                                      -9-
<PAGE>

5(c), 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. Notwithstanding anything to the contrary contained
herein, the Holder shall be liable or required to contribute under this Section
5(d) for only that amount as does not exceed the net proceeds to such Holder as
a result of the sale of Registrable Securities pursuant to such Registration
Statement.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) 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.
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.

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

      6.  Rule 144.
          --------

          As long as any Holder owns Registrable Securities, the Company
covenants to use its best efforts to timely file (or obtain extensions in
respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to Section
13(a) or 15(d) of the Exchange Act.  As long as any Holder owns Registrable
Securities, if the Company is not required to file reports pursuant to Section
13(a) or 15(d) of the Exchange Act, it will prepare and furnish to the Holders
and make publicly available in accordance with Rule 144(c) promulgated under the
Securities Act annual and quarterly financial statements, together with a
discussion and analysis of such financial statements in form and substance
substantially similar to those that would otherwise be required to be included
in reports required by Section 13(a) or 15(d) of the Exchange Act, as well as
any other information required thereby, in the time period that such filings
would have been required to have been made under the Exchange Act.  The Company
further covenants that it will take such further action as any Holder may
reasonably request, all to the extent required from time to time to enable such
Person to sell Shares without registration under the Securities Act within the
limitation of the exemptions provided by Rule 144 promulgated under the
Securities Act.

     7.  Miscellaneous.
         -------------

        (a) Failure to File Registration Statement and Other Events. The Company
            -------------------------------------------------------
and the Purchasers agree that the Holders will suffer damages if the
Registration Statement is not filed on or prior to the Filing Date and not
declared effective by the Commission on or prior to the Effectiveness Date and
maintained in the manner contemplated herein during the Effectiveness Period or
if certain other events occur. The Company and the Holders further agree that it
would not be feasible to ascertain the extent of such damages with precision. If
(i) the Registration Statement is not filed on or prior to the Filing Date, or
is not declared effective by the Commission on or prior to the Effectiveness
Date, or (ii) the Company fails to file with the Commission a request for
acceleration in accordance with Rule 461 promulgated under the

                                     -10-
<PAGE>

Securities Act within five (5) Business Days of the date that the Company is
notified (orally or in writing, whichever is earlier) by the Commission that a
Registration Statement will not be "reviewed," or not subject to further review
(any such failure being referred to as an "Event"), the Company shall pay as
                                           -----
liquidated damages for such failure and not as a penalty (the "Liquidated
                                                               ----------
Damages") to each Holder an amount equal to one percent (1%) of such Holder's
-------
pro rata share of the purchase price paid by all Holders for the Shares
purchased pursuant to the Purchase Agreement for each thirty (30) day period
following such Event until the applicable Event has been cured, which amount
shall be pro rated for any period less than thirty (30) days (the "Periodic
                                                                   --------
Amount"); provided that such delay was not caused by the Holders. Payments to be
------
made pursuant to this Section 7(a) shall be due and payable immediately upon
demand in shares of Common Stock. The parties agree that the Periodic Amount
represents a reasonable estimate on the part of the parties, as of the date of
this Agreement, of the amount of damages that may be incurred by the Holders if
the Registration Statement is not filed on or prior to the Filing Date or has
not been declared effective by the Commission on or prior to the Effectiveness
Date.

        (b) 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.

        (c)  Specific Enforcement, Consent to Jurisdiction.
             ---------------------------------------------

             (i)  The Company and the Holders acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent or cure breaches of the provisions of
this Agreement and to enforce specifically the terms and provisions hereof or
thereof, this being in addition to any other remedy to which any of them may be
entitled by law or equity.

             (ii) Each of the Company and the Holders (i) hereby irrevocably
submits to the jurisdiction of the United States District Court for the Southern
District of New York and the courts of the State of New York located in New York
county for the purposes of any suit, action or proceeding arising out of or
relating to this Agreement and (ii) hereby waives, and agrees not to assert in
any such suit, action or proceeding, any claim that it is not personally subject
to the jurisdiction of such court, that the suit, action or proceeding is
brought in an inconvenient forum or that the venue of the suit, action or
proceeding is improper. Each of the Company and the Holders consents to process
being served in any such suit, action or proceeding by mailing a copy thereof to
such party at the address in effect for notices to it under this Agreement and
agrees that such service shall constitute good and sufficient service of process

                                     -11-
<PAGE>

and notice thereof. Nothing in this Section shall affect or limit any right to
serve process in any other manner permitted by law.

        (d) Amendments and Waivers. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
given, unless the same shall be in writing and signed by the Company and Holders
of not less 51% of the Registrable Securities then owned by all Holders.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
Holders and that does not directly or indirectly affect the rights of other
Holders may be given by Holders of at least a majority of the Registrable
Securities to which such waiver or consent relates; provided, however, that the
provisions of this sentence may not be amended, modified, or supplemented except
in accordance with the provisions of the immediately preceding sentence.

        (e)  Notices.  Any and all notices or other communications or deliveries
             -------
required or permitted to be provided hereunder shall be in writing and shall be
deemed given and effective on the earlier of (i) the date of transmission, if
