necessary) on Form S-3 covering the resale of all Registrable Securities not
already covered by an existing and effective Registration Statement for an
offering to be made on a continuous basis pursuant to Rule 415. In the event
that Form S-3 is unavailable for such a registration, the Company shall use such
other form as is available for such a registration. Such Registration Statement
shall contain (except if otherwise required pursuant to written comments
received from the Commission upon a review of such Registration Statement) the
"Plan of Distribution" attached hereto as Annex A. The Company shall cause such
Registration Statement to be declared effective under the Securities Act as soon
as possible but, in any event, no later than its Effectiveness Date, and shall
use its reasonable best efforts to keep the Registration Statement continuously
effective under the Securities Act until the date which is the earlier of (i)
five (5) years after its Effective Date, (ii) such time as all of the

Rule 144(k) as determined by the counsel to the Company pursuant to a written
opinion letter to such effect, addressed and acceptable to the Company's
transfer agent and the affected Holders (the "EFFECTIVENESS PERIOD").

            (b) If for any reason the Commission does not permit all of the

pursuant to Section 2(a), or for any

                                       3

<PAGE>

other reason any outstanding Registrable Securities are not then covered by an
effective Registration Statement, then the Company shall prepare and file by the
Filing Date for such Registration Statement, an additional Registration
Statement covering the resale of all Registrable Securities not already covered
by an existing and effective Registration Statement for an offering to be made
on a continuous basis pursuant to Rule 415, on an appropriate form for such
purpose. Each such Registration Statement shall contain (except if otherwise
required pursuant to written comments received from the Commission upon a review
of such Registration Statement) the "Plan of Distribution" attached hereto as
Annex A. The Company shall cause each such Registration Statement to be declared
effective under the Securities Act as soon as possible but, in any event, by its
Effectiveness Date, and shall use its reasonable best efforts to keep such
Registration Statement continuously effective under the Securities Act during
the entire Effectiveness Period.

            (c) If: (i) a Registration Statement is not filed on or prior to its
Filing Date (if the Company files a Registration Statement without affording the
Holders the opportunity to review and comment on the same as required by Section
3(a) hereof, the Company shall not be deemed to have satisfied this clause (i)),
or (ii) a Registration Statement is not declared effective by the Commission on
or prior to its required Effectiveness Date, or (iii) after its Effective Date,
without regard for the reason thereunder or efforts therefore, such Registration
Statement ceases for any reason to be effective and/or available to the Holders
as to all Registrable Securities to which it is required to cover at any time
prior to the expiration of its Effectiveness Period, the Company agrees to use
its reasonable best efforts to keep the Registration Statement continuously
effective under the Securities Act for an additional period of time, beginning
on the last day of the Effectiveness Period, equal to the aggregate amount of
days that passed before the Company cured any and all events referred to in
clauses (i), (ii) and (iii) herein.

            (d) Each Holder agrees to furnish to the Company a completed
Questionnaire in the form attached to this Agreement as Annex B (a "SELLING
HOLDER QUESTIONNAIRE"). The Company shall not be required to include the
Registrable Securities of a Holder in a Registration Statement who fails to
furnish to the Company a fully completed Selling Holder Questionnaire at least
two Trading Days prior to the Filing Date (subject to the requirements set forth
in Section 3(a)).

            (e) In the event that Form S-3 is not available for any registration
of Registrable Securities hereunder, the Company shall (i) register the sale of
the Registrable Securities on another appropriate form and (ii) undertake to
register the Registrable Securities on Form S-3 as soon as such form is
available; provided, however, that the Company shall maintain the effectiveness
of the Registration Statement then in effect until such time as a Registration
Statement on Form S-3 covering the Registrable Securities has been declared
effective by the Commission.

      3.    Registration Procedures.

            In connection with the Company's registration obligations hereunder,
the Company shall:

                                       4

<PAGE>

            (a) As promptly as reasonably possible prior to the filing of a
Registration Statement or any related Prospectus or any amendment or supplement
thereto, the Company shall furnish to each Holder copies of the "Selling
Stockholders" section of such document, the "Plan of Distribution" and any risk
factor contained in such document that addresses specifically this transaction
or the Selling Stockholders, as proposed to be filed, which documents will be
subject to the review of such Holder. The Company shall not file a Registration
Statement, any Prospectus or any amendments or supplements thereto in which the
"Selling Stockholder" section thereof differs in any material respect from the
disclosure received from a Holder in its Selling Holder Questionnaire (as
amended or supplemented).

            (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to each Registration Statement and the
Prospectus used in connection therewith as may be necessary to keep such
Registration Statement continuously effective as to the applicable Registrable
Securities for its Effectiveness Period and prepare and file with the Commission
such additional Registration Statements in order to register for resale under
the Securities Act all of the Registrable Securities; (ii) cause the related
Prospectus to be amended or supplemented by any required Prospectus supplement,
and as so supplemented or amended to be filed pursuant to Rule 424; (iii)
respond as promptly as reasonably possible to any comments received from the
Commission with respect to each Registration Statement or any amendment thereto;
and (iv) comply in all material respects with the provisions of the Securities
Act and the Exchange Act with respect to the Registration Statements and the
disposition of all Registrable Securities covered by each Registration
Statement.

            (c) Notify the Holders as promptly as reasonably possible (and,
except with respect to (i)(B) below, within one Trading Day) and, if requested
by any such Person confirm such notice in writing (i)(A) when a Prospectus or
any Prospectus supplement or post-effective amendment to a 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 (the Company shall
provide true and complete copies thereof and all written responses thereto to
each of the Holders that pertain to each such Holder as a selling Holder or to
the Plan of Distribution, but not information which the Company believes would
constitute material and non-public information); and (C) with respect to each
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 for amendments or supplements to a Registration Statement
or Prospectus or for additional information; (iii) of the issuance by the
Commission of any stop order suspending the effectiveness of a Registration
Statement covering any or all of the Registrable Securities or the initiation of
any Proceedings for that purpose; (iv) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (v) of the occurrence of any event or passage of time that makes
the financial statements included in a Registration Statement ineligible for
inclusion therein or any statement made in such 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 such
Registration Statement, Prospectus or other documents so that, in the case of
such Registration Statement or the Prospectus, as the case may be, it will not
contain any untrue statement of a material fact or omit

                                       5

<PAGE>

to state any material fact required to be stated therein or necessary to make
the statements therein, in 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 a
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.

            (e) Furnish to each Holder, without charge, at least one conformed
copy of each Registration Statement and each amendment thereto and all exhibits
to the extent requested by such Person (including those previously furnished)
promptly after the filing of such documents with the Commission.

            (f) Promptly deliver to each Holder, without charge, as many copies
of each Prospectus or Prospectuses (including each form of prospectus) and each
amendment or supplement thereto as such Persons may reasonably request. The
Company hereby consents to the use of such Prospectus and each amendment or
supplement thereto by each of the selling Holders in connection with the
offering and sale of the Registrable Securities covered by such Prospectus and
any amendment or supplement thereto.

            (g) Prior to any public offering of Registrable Securities, use
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 all applicable securities or Blue Sky laws, 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 or
advisable to enable the disposition in such jurisdictions of the Registrable
Securities covered by the Registration Statements; 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 tax in any such jurisdiction
where it is not then so subject.

            (h) Cooperate with the Holders to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be delivered
to a transferee pursuant to the Registration Statements, which certificates
shall be free, to the extent permitted by the Purchase Agreement, of all
restrictive legends, and to enable such Registrable Securities to be in such
denominations and registered in such names as any such Holders may request.

            (i) Upon the occurrence of any event contemplated by Section
3(c)(v), as promptly as reasonably possible, prepare a supplement or amendment,
including a post-effective amendment, to the affected Registration Statements 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, no Registration Statement nor any 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
light of the circumstances under which they were made, not misleading.

                                       6

      4. Registration Expenses. All reasonable fees and expenses incident to the
performance of or compliance with this Agreement by the Company (excluding
underwriting, brokerage and other selling commissions and discounts) shall be
borne by the Company whether or not any Registrable Securities are sold pursuant
to a Registration Statement. The fees and expenses referred to in the foregoing
sentence shall include, without limitation, (i) all registration and filing fees
(including, without limitation, fees and expenses (A) with respect to filings
required to be made with any Trading Market on which the Common Stock is then
listed for trading, and (B) in compliance with applicable state securities or
Blue Sky laws, (ii) printing expenses (including, without limitation, expenses
of printing certificates for Registrable Securities and of printing prospectuses
if the printing of prospectuses is reasonably requested by the holders of a
majority of the Registrable Securities included in the Registration Statement),

counsel for the Company, (v) Securities Act liability insurance, if the Company
so desires such insurance, and (vi) fees and expenses of all other Persons

for all of its internal expenses incurred in connection with the consummation of
the transactions contemplated by this Agreement (including, without limitation,
all salaries and expenses of its officers and employees performing legal or
accounting duties), the expense of any annual audit and the fees and expenses
incurred in connection with the listing of the Registrable Securities on any
securities exchange as required hereunder.

      5. Indemnification.

            (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents, investment advisors, partners,
members and employees of each of them, each Person who controls any such Holder
(within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act) and the officers, directors, agents and employees of each such
controlling Person, to the fullest extent permitted by applicable law, from and
against any and all losses, claims, damages, liabilities, costs (including,
without limitation, reasonable costs of preparation and reasonable attorneys'
fees) and expenses (collectively, "LOSSES"), (which Losses shall not include any
diminution in value of the Registrable Securities), 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, except to the extent, but only to the extent, that (1) 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, 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
the Registration Statement, such Prospectus or such form of Prospectus or in any
amendment or supplement thereto (it being understood that the Holder has
approved Annex A hereto for this purpose) or (2) in the case of an occurrence of
an event of the type specified in Section 3(c)(ii)-(v), the use by such Holder
of an outdated or defective Prospectus after the Company has notified such
Holder in writing that the Prospectus is

                                       7

<PAGE>

outdated or defective and prior to the receipt by such Holder of an Advice or an
amended or supplemented Prospectus, but only if and to the extent that following
the receipt of the Advice or the amended or supplemented Prospectus the
misstatement or omission giving rise to such Loss would have been corrected. 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.

            (b) Indemnification by Holders. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company, its 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
incurred, arising solely out of or based solely upon: (x) such Holder's failure
to comply with the prospectus delivery requirements of the Securities Act or (y)
any 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 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 not misleading to the extent, but only to the extent that, (1) 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, 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
the Registration Statement (it being understood that the Holder has approved
Annex A hereto for this purpose), such Prospectus or such form of Prospectus or
in any amendment or supplement thereto or (2) in the case of an occurrence of an
event of the type specified in Section 3(c)(ii)-(v), the use by such Holder of
an outdated or defective Prospectus after the Company has notified such Holder
in writing that the Prospectus is outdated or defective and prior to the receipt
by such Holder of an Advice or an amended or supplemented Prospectus, but only
if and to the extent that following the receipt of the Advice or the amended or
supplemented Prospectus the misstatement or omission giving rise to such Loss
would have been corrected. 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.

            (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 shall promptly 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.

                                       8

<PAGE>

      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; (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 does not include an admission of wrongdoing by the Indemnified
Party, does not require the Indemnified Party to take or refrain from taking any
action and 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 Trading
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 (by reason of public policy or
otherwise) or insufficient to hold an Indemnified Party harmless, then each
Indemnifying 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 in Section 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.

                                       9

<PAGE>

      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.
Notwithstanding the provisions of this Section 5(d), no Holder shall be required
to contribute, in the aggregate, any amount in excess of the amount by which the
proceeds actually received by such Holder from the sale of the Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission.

      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. Sales Limitation. Each Holder agrees during the Effectiveness Period to
limit the number of Registrable Securities sold by such Holder in the public
market in any trading day to the Sale Limitation Amount.

      7. Miscellaneous.

            (a) 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.

            (b) Compliance. Each Holder covenants and agrees that it will comply
with the prospectus delivery requirements of the Securities Act as applicable to
it in connection with sales of Registrable Securities pursuant to the
Registration Statement.

            (c) Discontinued Disposition. 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), 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 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. The
Company may provide appropriate stop orders to enforce the provisions of this
paragraph.

            (d) Piggy-Back Registrations. If at any time during the
Effectiveness Period there is not an effective Registration Statement covering
all of the Registrable Securities and the Company shall determine to prepare and
file with the Commission a registration statement relating to an offering for
its own account or the account of others under the Securities Act of

                                       10

any of its equity securities, other than on Form S-4 or Form S-8 (each as
promulgated under the Securities Act) or their then equivalents relating to
equity securities to be issued solely in connection with any acquisition of any
entity or business or equity securities issuable in connection with stock option
or other employee benefit plans, then the Company shall send to each Holder
written notice of such determination and, if within fifteen days after receipt
of such notice, any such Holder shall so request in writing, the Company shall
include in such registration statement all or any part of such Registrable
Securities such holder requests to be registered, subject to customary
underwriter cutbacks applicable to all holders of registration rights.

            (e) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this Section 7(e), 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 the Holders of no less than a majority in interest of the then outstanding
Registrable Securities. 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 certain 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.

            (f) Notices. Any and all notices or other communications or
deliveries require or permitted to be provided hereunder shall be in writing and
shall be deemed given and effective when delivered in the manner set forth in
Section 6(c) of the Purchase Agreement.

            (g) 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 and shall inure to the benefit of each Holder. Other than in
connection with a merger, consolidation, sale of all or substantially all of the
Company's assets or other similar change in control transaction, the Company may
not assign its rights or obligations hereunder without the prior written consent
of each Holder. Each Holder may assign their respective rights hereunder in the
manner and to the Persons as permitted under the Purchase Agreement.

            (h) Execution and Counterparts. This Agreement may be executed in
any number of counterparts, each of which when so executed shall be deemed to be
an original and, all of which taken together shall constitute one and the same
Agreement. In the event that any signature is delivered by facsimile
transmission, such signature shall create a valid binding obligation of the
party executing (or on whose behalf such signature is executed) the same with
the same force and effect as if such facsimile signature were the original
thereof.

            (i) Governing Law. This Agreement shall be governed by, and
construed in accordance with, the internal laws of the State of Delaware without
regard to the choice of law principles thereof.

            (j) Cumulative Remedies. The remedies provided herein are cumulative
and not exclusive of any remedies provided by law.

            (k) 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.

            (l) Headings. The headings in this Agreement are for convenience of
