Company does not file the Registration Statement or any Prospectus or amendments
or supplements as required hereunder as a result of such an objection.

                  (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 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 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond promptly to any comments received from the
Commission with respect to the Registration Statement or any amendment thereto

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 Holder of Registrable Securities to be sold and
any Special Counsel promptly (and, in the case of (i)(A) below, not less than
three (3) Business Days prior to such filing) and (if requested by any such

(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
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the 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 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.

                  The Company shall promptly furnish to Special Counsel, without
charge, (i) any correspondence from the Commission or the Commission's staff to
the Company or its representatives relating to any Registration Statement and
(ii) promptly after the same is prepared and filed with the Commission, a copy
of any written response to the correspondence received from the Commission.

                  (d) Use its commercially reasonable best efforts to avoid the

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 U.S. jurisdiction, at the earliest practicable
moment.

                  (e) If requested by the Holder, (i) promptly incorporate in a
Prospectus supplement or post-effective amendment to the Registration Statement
such information as the Company reasonably agrees should be included therein and
(ii) make all required filings of such Prospectus supplement or such
post-effective amendment as soon as practicable after the Company has received
notification of the matters to be incorporated in such Prospectus supplement or
post-effective amendment.

                  (f) Furnish to the Holder and any Special Counsel, without
charge, at least one conformed copy of each Registration Statement and each
amendment thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

                  (g) Promptly deliver to the Holder and any Special Counsel,
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

                                      -5-
<PAGE>

request; and the Company hereby consents to the use of such Prospectus and each
amendment or supplement thereto by the selling Holder in connection with the
offering and sale of the Registrable Securities covered by such Prospectus and
any amendment or supplement thereto.

                  (h) Prior to any public offering of Registrable Securities,
use its commercially reasonable best efforts to register or qualify or cooperate
with the selling Holders and any Special Counsel 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
the Holder reasonably 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 or advisable 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.

                  (i) Cooperate with the Holder to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold pursuant to a Registration Statement and to enable such Registrable
Securities to be in such denominations and registered in such names as the
Holder may request at least two (2) Business Days prior to any sale of
Registrable Securities.

                  (j) Upon the occurrence of any event contemplated by Section
3(c)(v), promptly 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.

                  (k) Use its commercially reasonable best efforts to cause all
Registrable Securities relating to such Registration Statement to be listed on
the NYSE and any other securities exchange, quotation system, market or
over-the-counter bulletin board, if any, on which the same securities issued by
the Company are then listed as and when required pursuant to the Purchase
Agreement.

                  (l) Use its commercially reasonable efforts to 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 twelve (12) month
period (or ninety (90) days after the end of any twelve (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.

                                      -6-
<PAGE>

                  (m) If the Registration Statement refers to the Holder by name
or otherwise as the holder of any securities of the Company, then the Holder
shall have the right to require (if such reference to the 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 the Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

                  The 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(g) 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) it will 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
the Holder if it fails to furnish such information within a reasonable time
prior to the filing of each Registration Statement, supplemented Prospectus
and/or amended Registration Statement.

                  The 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),
3(c)(v) or 3(n), it will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until the Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(j), or until it is advised in writing 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.

                  (n) 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 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 not to exceed forty-five (45) consecutive
days, provided that the Company may not suspend its obligation pursuant to this
Section 3(n) for more than sixty (60) days in the aggregate during any twelve
(12) month period (each, a "Blackout Period"); provided, however, that no such
suspension shall be permitted for consecutive forty-five (45) day periods,
arising out of the same set of facts, circumstances or transactions.

                  (o) Within two (2) Business Days after the Registration
Statement which includes the Registrable Securities is ordered effective by the
Commission, the Company shall

                                      -7-
<PAGE>

deliver, and shall cause legal counsel for the Company to deliver, to the
transfer agent for such Registrable Securities (with copies to the Holder whose
Registrable Securities are included in such Registration Statement) confirmation
that the Registration Statement has been declared effective by the Commission in
the form attached hereto as Exhibit B.

                  (p) (i) The Company may enter into an agreement with a third
party before the Filing Date or the Effectiveness Date, the principal purpose of

herein, Other Financing shall exclude the Company (i) entering into a loan,
credit or lease facility with a bank or financing institution (including any
equity component thereof), (ii) establishing an employee stock option plan or
agreement, (iii) issuing shares of Common Stock in connection with the Company's
employee or director option plans (as the same may be amended from time to
time), stock purchase plans, rights plans, currently outstanding warrants or
options (unless the exercise price of such warrants or options are reset to a
price below the current exercise price), or increase the number of shares
available under any such plans (the primary purpose of which is to not to raise
equity), and (iv) issuing shares of Common Stock and/or preferred stock in
connection with the formation or maintenance of strategic partnerships,
alliances, licenses or joint ventures and the acquisition of products, licenses
or other assets. If the Other Financing occurs before the Filing Date at a price
per share less than the average purchase price, then the average purchase price
shall be reset to the third party's terms, net of third party discounts and
expenses.

                      (ii) If the Company enters into an Other Financing before
the effectiveness of the Registration Statement at a price per share less than
$21.00, adjusted for any stock dividends, stock splits or other similar
transactions, the Company will issue additional shares to the Purchaser based on
standard "weighted average" anti-dilution formula set forth on Exhibit C
attached hereto (the "Anti-Dilution Shares"). If issued, the Anti-Dilution
Shares shall, at the Purchaser's option, if appropriate and if in excess of
100,000 shares, be registered in a separate registration statement.

         4. Registration Expenses

                  All reasonable fees and expenses incident to the performance

any failure to perform under a margin call of Common Stock), investment advisors
and employees, each Person who controls any such Purchaser or permitted assignee

attorneys' fees and expenses) (collectively, "Losses"), arising out of or
relating to any untrue or alleged untrue statement of a material fact contained

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 (i) to the extent, but only to the extent, that
such untrue statements or omissions are based solely upon information regarding
the Holder or the Holder's proposed method of distribution of Registrable
Securities furnished in writing to the Company by the Holder expressly for use
therein and (ii) as a result of the failure of the Holder to deliver a
Prospectus, as amended or supplemented, to a purchaser in connection with an

each Person who controls the Company (within the meaning of Section 15 of the

fullest extent permitted by applicable law, from and against all 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, as
supplemented or amended, if applicable, or arising

                                      -9-
<PAGE>

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, (i) to
the extent, but only to the extent, that such untrue statements or omissions are
based solely upon information regarding the Holder or the Holder's proposed
method of distribution of Registrable Securities furnished in writing to the
Company by the Holder expressly for use therein and (ii) as a result of the
failure of Holder to deliver a Prospectus, as amended or supplemented, to a
purchaser in connection with an offer or sale. 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 the 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 pursuant
to Section 5(a) or 5(b) 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 materially and 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 reasonably acceptable to
the Indemnifying Party 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, which consent shall not unreasonably be
withheld, 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 reasonable fees and expenses of the Indemnified Party
(including reasonable fees and expenses to the extent incurred in connection
with investigating or preparing to defend

                                      -10-
<PAGE>

such Proceeding in a manner not inconsistent with this Section) shall be paid to
the Indemnified Party, as incurred, within twenty (20) 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 or pursuant to applicable law).

                  (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) (other than
by reason of exceptions provided in those Sections), 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 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
under Section 5(a) or 5(b) 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 the 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 the Holder owns Registrable Securities, the Company
covenants 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

                                      -11-
<PAGE>

15(d) of the Exchange Act and to promptly furnish the Holders with true and
complete copies of all such filings. As long as the 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 the Holder may
reasonably request, all to the extent required from time to time to enable the
Holder to sell Common Shares 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 of counsel to the
Company referred to in the Purchase Agreement. Upon the request of any Holder,
the Company shall deliver to such Holder a written certification of a duly
authorized officer as to whether it has complied with such requirements.

         7. Miscellaneous.

                  (a) Remedies. In the event of a breach by the Company or by
the Holder, of any of their obligations under this Agreement, the 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 the 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) No Inconsistent Agreements. Neither the Company nor any of
its subsidiaries has, as of the date hereof entered into and currently in
effect, nor shall the Company or any of its Affiliates, 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. Without limiting the generality
of the foregoing, without the written consent of the Holder, 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 if the rights so granted are
inconsistent with the rights granted to Holders set forth herein, or otherwise
prevent the Company with complying with all of its obligations hereunder.

                  (c) No Piggyback on Registrations. Neither the Company nor any
of its security holders (other than the Holders in such capacity pursuant
hereto) may include securities of the Company in the Registration Statement.

                  (d) Failure to File Registration Statement and Other Events.
The Company and the Holders 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

                                      -12-
<PAGE>

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. Accordingly, 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
12d1-2 promulgated under the Exchange 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, or (iii) the Registration Statement is filed with and
declared effective by the Commission but thereafter ceases to be effective as to
all Registrable Securities at any time during the Effectiveness Period, without
being succeeded within a reasonable period by a subsequent Registration
Statement filed with and declared effective by the Commission, or (iv) during
the Period, trading in the Common Stock shall be suspended for any reason for
more than three (3) Business Days in the aggregate (for purposes of this clause
(iv), the term Business Day shall not include any day on which the NYSE is
closed for trading), or (v) the Company has breached Section 3(n) of this
Agreement (any such failure or breach 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 the Holder an amount equal to two percent (2%) of
the purchase price paid by the Holder for all Registrable Securities then held
by the Holder for each thirty (30) day period, pro rated for any period less
than thirty (30) days (except with respect to the Registration Statement not
being declared effective by the Effectiveness Date pursuant to clause (i) of
this Section 7(d)), following the Event until the applicable Event has been
cured. Notwithstanding anything in the foregoing to the contrary, in the event
that the Commission has notified the Company that the Registration Statement
will not be "reviewed" or subject to further review and the Company determines
that it cannot request acceleration of the Registration Statement because the
Company is required to disclose certain material, non-public information, then
Liquidated Damages shall not accrue for a period of forty-five (45) days
following the fifth (5th) Business Day after which the Company had received such
notice from the Commission. The combined aggregate Liquidated Damages payable by
the Company for delayed filing of the registration statement or delayed
effectiveness beyond the Effectiveness Date shall not exceed sixteen percent
(16%) of the purchase price paid by the Purchaser for the Registrable Securities
and Liquidated Damages shall cease to accrue after the date on which Purchaser
would be able to sell all such Registrable Securities held by it without
restriction pursuant to Rule 144(k) promulgated under the Securities Act.
Payments to be made pursuant to this Section 7(d) shall be due and payable
immediately upon demand at the option of the Holders in cash. The parties agree
that the Liquidated Damages represent 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 and maintained in the manner contemplated herein
during the Effectiveness Period or if any other Event as described herein has
occurred.

                  (e) Consent to Jurisdiction.

                           (i) Both the Company and the Purchaser (i) hereby
irrevocably submit 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 or the Purchase Agreement and

                                      -13-
<PAGE>

(ii) hereby waive, and agree 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. Both the
Company and the Purchaser consent 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 and notice thereof. Nothing in
this Section 7(e) shall affect or limit any right to serve process in any other
manner permitted by law.

                  (f) 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 the Purchaser.

                  (g) 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 such notice or communication is delivered via facsimile at the
facsimile telephone number specified for notice prior to 5:00 p.m., eastern
standard time, on a Business Day, (ii) the first Business Day after the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified for notice later than 5:00 p.m., eastern
time, on any date and earlier than 11:59 p.m., eastern time, on such date, (iii)
the Business Day following the date of mailing, if sent by nationally recognized
overnight courier service or (iv) actual receipt by the party to whom such
notice is required to be given.

by such notice.

                  (h) Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties and their successors and permitted
assigns and shall inure to the benefit of the Holder and its successors and
assigns. Except in accordance with Section 7(i) below, neither the Purchaser nor
the Company may assign this Agreement or any of its respective rights or
obligations hereunder without the prior written consent of the other party.

                  (i) Assignment of Registration Rights. The rights of the
Holder hereunder, including the right to have the Company register for resale
Registrable Securities in accordance with the terms of this Agreement, shall be
assignable by each Holder to any transferee of the Holder of all or a portion of
the shares of Registrable Securities if: (i) 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, (ii)
the Company is, within a reasonable time after such transfer or assignment,
furnished with written notice of (a) the name and address of such transferee or
assignee, and (b) the securities with respect to which such registration rights
are being transferred or assigned, (iii) following such transfer or assignment
the further disposition of such securities by the transferee or assignees is
restricted under the Securities Act and applicable state securities laws, (iv)
at or before the time the Company receives the written notice contemplated by
clause (ii) of this Section, the transferee or assignee agrees in writing with
the Company to be bound by all of the provisions of this Agreement, and (v) such
transfer shall have been made in accordance with the applicable requirements of
the Purchase Agreement and shall be for no less than 50% of the Registrable
Securities. In addition, the Holder shall have the right to assign its rights
hereunder to any other Person with the prior written consent of the Company,
which consent shall not be unreasonably withheld. The rights to assignment shall
apply to the Holder (and to subsequent) successors and

                                      -15-
<PAGE>

assigns. In the event of an assignment pursuant to this Section 7(i), the
Purchaser shall pay all incremental costs and expenses incurred by the Company
in connection with filing a Registration Statement (or an amendment to the
Registration Statement) to register the shares of Registrable Securities
assigned to any assignee or transferee of the Purchaser.

                  (j) 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.

                  (k) Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without regard
to principles of conflicts of law thereof. This Agreement shall not be
interpreted or construed with any presumption against the party causing this
Agreement to be drafted.

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

                  (m) Termination. This Agreement shall terminate on the date on
which all remaining Registrable Securities may be sold without restriction
pursuant to Rule 144(k) of the Securities Act.

                  (n) Severability. If any term, provision, covenant or
restriction of this Agreement is held to be invalid, illegal, void or
unenforceable in any respect, 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.

                  (o) Headings. The headings herein are for convenience only, do
not constitute a part of this Agreement and shall not be deemed to limit or
affect any of the provisions hereof.

                          REGISTRATION RIGHTS AGREEMENT

                  This Registration Rights Agreement is made and entered into as
of March 6, 2002 (this "Agreement"), by and between Trinity Industries, Inc., a
Delaware corporation (the "Company"), and Acqua Wellington Opportunity I
Limited, a company organized under the laws of the Commonwealth of the Bahamas
(the "Purchaser").

                  This Agreement is being entered into pursuant to the Purchase
Agreement, dated as of the date hereof, by and between the Company and the
Purchaser (the "Purchase Agreement").

                  The Company and the Purchaser hereby agree as follows:

         1. Definitions.

                  Capitalized terms used and not otherwise defined herein shall

or supplements as required hereunder as a result of such an objection.

                  (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 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 (or any similar provisions then in force) promulgated under the

                  (c) Notify the Holder of Registrable Securities to be sold and
any Special Counsel promptly (and, in the case of (i)(A) below, not less than
three (3) Business Days prior to such filing) and (if requested by any such

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
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the 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 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.

                  The Company shall promptly furnish to Special Counsel, without
charge, (i) any correspondence from the Commission or the Commission's staff to
the Company or its representatives relating to any Registration Statement and
(ii) promptly after the same is prepared and filed with the Commission, a copy

moment.

                  (e) If requested by the Holder, (i) promptly incorporate in a
Prospectus supplement or post-effective amendment to the Registration Statement
such information as the Company reasonably agrees should be included therein and
(ii) make all required filings of such Prospectus supplement or such
post-effective amendment as soon as practicable after the Company has received
notification of the matters to be incorporated in such Prospectus supplement or
post-effective amendment.

                  (f) Furnish to the Holder and any Special Counsel, without
charge, at least one conformed copy of each Registration Statement and each
amendment thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

                  (g) Promptly deliver to the Holder and any Special Counsel,
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

                                       5
<PAGE>

request; and the Company hereby consents to the use of such Prospectus and each
amendment or supplement thereto by the selling Holder in connection with the
offering and sale of the Registrable Securities covered by such Prospectus and
any amendment or supplement thereto.

                  (h) Prior to any public offering of Registrable Securities,
use its commercially reasonable best efforts to register or qualify or cooperate
with the selling Holders and any Special Counsel 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
the Holder reasonably 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 or advisable 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.

                  (i) Cooperate with the Holder to facilitate the timely
preparation and delivery of certificates representing Registrable Securities to
be sold pursuant to a Registration Statement and to enable such Registrable
Securities to be in such denominations and registered in such names as the
Holder may request at least two (2) Business Days prior to any sale of
Registrable Securities.

                  (j) Upon the occurrence of any event contemplated by Section
3(c)(v), promptly 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.

                  (k) Use its commercially reasonable best efforts to cause all
Registrable Securities relating to such Registration Statement to be listed on
the NYSE and any other securities exchange, quotation system, market or
over-the-counter bulletin board, if any, on which the same securities issued by
the Company are then listed as and when required pursuant to the Purchase
Agreement.

                  (l) Use its commercially reasonable efforts to comply in all
material respects with all applicable rules and regulations of the Commission

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 twelve (12) month
period (or ninety (90) days after the end of any twelve (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.

                                       6
<PAGE>

                  (m) If the Registration Statement refers to the Holder by name
or otherwise as the holder of any securities of the Company, then the Holder
shall have the right to require (if such reference to the 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 the Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

                  The 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(g) 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) it will 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
the Holder if it fails to furnish such information within a reasonable time
prior to the filing of each Registration Statement, supplemented Prospectus
and/or amended Registration Statement.

                  The 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),
3(c)(v) or 3(n), it will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until the Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(j), or until it is advised in writing 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.

                  (n) 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 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 not to exceed forty-five (45) consecutive
days, provided that the Company may not suspend its obligation pursuant to this
Section 3(n) for more than sixty (60) days in the aggregate during any twelve
(12) month period (each, a "Blackout Period"); provided, however, that no such
suspension shall be permitted for consecutive forty-five (45) day periods,
arising out of the same set of facts, circumstances or transactions.

                  (o) Within two (2) Business Days after the Registration
Statement which includes the Registrable Securities is ordered effective by the
Commission, the Company shall

                                       7
<PAGE>

deliver, and shall cause legal counsel for the Company to deliver, to the
transfer agent for such Registrable Securities (with copies to the Holder whose
Registrable Securities are included in such Registration Statement) confirmation
that the Registration Statement has been declared effective by the Commission in
the form attached hereto as Exhibit B.

                  (p) (i) The Company may enter into an agreement with a third
party before the Filing Date or the Effectiveness Date, the principal purpose of

herein, Other Financing shall exclude the Company (i) entering into a loan,
credit or lease facility with a bank or financing institution (including any

price below the current exercise price), or increase the number of shares
available under any such plans (the primary purpose of which is to not to raise
equity), and (iv) issuing shares of Common Stock and/or preferred stock in
connection with the formation or maintenance of strategic partnerships,
alliances, licenses or joint ventures and the acquisition of products, licenses
or other assets. If the Other Financing occurs before the Filing Date at a price
per share less than the average purchase price, then the average purchase price
shall be reset to the third party's terms, net of third party discounts and
expenses.

                      (ii) If the Company enters into an Other Financing before
the effectiveness of the Registration Statement at a price per share less than
$21.00, adjusted for any stock dividends, stock splits or other similar
transactions, the Company will issue additional shares to the Purchaser based on
standard "weighted average" anti-dilution formula set forth on Exhibit C
attached hereto (the "Anti-Dilution Shares"). If issued, the Anti-Dilution
Shares shall, at the Purchaser's option, if appropriate and if in excess of
100,000 shares, be registered in a separate registration statement.

         4. Registration Expenses

                  All reasonable fees and expenses incident to the performance

any failure to perform under a margin call of Common Stock), investment advisors
and employees, each Person who controls any such Purchaser or permitted assignee
(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, and the respective successors, assigns, estate and personal
representatives of each of the foregoing, to the fullest extent permitted by

of investigation) and expenses (including, without limitation, reasonable
attorneys' fees and expenses) (collectively, "Losses"), arising out of or
relating to any untrue or alleged untrue statement of a material fact contained
in the Registration Statement, any Prospectus, as supplemented or amended, if
applicable, 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 (i) to the extent, but only to the extent, that
such untrue statements or omissions are based solely upon information regarding
the Holder or the Holder's proposed method of distribution of Registrable
Securities furnished in writing to the Company by the Holder expressly for use
therein and (ii) as a result of the failure of the Holder to deliver a
Prospectus, as amended or supplemented, to a purchaser in connection with an
offer or sale. The Company shall notify the Holder 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 remain in full force and effect regardless of any investigation made by or
on behalf of an Indemnified Party (as defined in Section 5(c) hereof) and shall
survive the transfer of the Registrable Securities by the Holder.

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,

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 out of or relating to any untrue or alleged untrue statement
of a material fact contained in the Registration Statement, any Prospectus, as
supplemented or amended, if applicable, or arising

                                       9
<PAGE>

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, (i) to
the extent, but only to the extent, that such untrue statements or omissions are
based solely upon information regarding the Holder or the Holder's proposed
method of distribution of Registrable Securities furnished in writing to the
Company by the Holder expressly for use therein and (ii) as a result of the
failure of Holder to deliver a Prospectus, as amended or supplemented, to a
purchaser in connection with an offer or sale. 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 the 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 pursuant
to Section 5(a) or 5(b) 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 materially and 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 reasonably acceptable to
the Indemnifying Party 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, which consent shall not unreasonably be
withheld, 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 reasonable fees and expenses of the Indemnified Party
(including reasonable fees and expenses to the extent incurred in connection
with investigating or preparing to defend

                                       10
<PAGE>

such Proceeding in a manner not inconsistent with this Section) shall be paid to
the Indemnified Party, as incurred, within twenty (20) 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 or pursuant to applicable law).

                  (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) (other than
by reason of exceptions provided in those Sections), 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 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
under Section 5(a) or 5(b) 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 the 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 the Holder owns Registrable Securities, the Company
covenants 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

                                       11
<PAGE>

15(d) of the Exchange Act and to promptly furnish the Holders with true and
complete copies of all such filings. As long as the 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 the Holder may
reasonably request, all to the extent required from time to time to enable the
Holder to sell Common Shares 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 of counsel to the
Company referred to in the Purchase Agreement. Upon the request of any Holder,
the Company shall deliver to such Holder a written certification of a duly
authorized officer as to whether it has complied with such requirements.

         7. Miscellaneous.

                  (a) Remedies. In the event of a breach by the Company or by
the Holder, of any of their obligations under this Agreement, the 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 the 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) No Inconsistent Agreements. Neither the Company nor any of
its subsidiaries has, as of the date hereof entered into and currently in
effect, nor shall the Company or any of its Affiliates, 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. Without limiting the generality
of the foregoing, without the written consent of the Holder, 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 if the rights so granted are
inconsistent with the rights granted to Holders set forth herein, or otherwise
prevent the Company with complying with all of its obligations hereunder.

                  (c) No Piggyback on Registrations. Neither the Company nor any
of its security holders (other than the Holders in such capacity pursuant
hereto) may include securities of the Company in the Registration Statement.

                  (d) Failure to File Registration Statement and Other Events.
The Company and the Holders 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

                                       12
<PAGE>

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. Accordingly, 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
12d1-2 promulgated under the Exchange 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, or (iii) the Registration Statement is filed with and
declared effective by the Commission but thereafter ceases to be effective as to
all Registrable Securities at any time during the Effectiveness Period, without
being succeeded within a reasonable period by a subsequent Registration
Statement filed with and declared effective by the Commission, or (iv) during
the Period, trading in the Common Stock shall be suspended for any reason for
more than three (3) Business Days in the aggregate (for purposes of this clause
(iv), the term Business Day shall not include any day on which the NYSE is
closed for trading), or (v) the Company has breached Section 3(n) of this
Agreement (any such failure or breach 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 the Holder an amount equal to two percent (2%) of
the purchase price paid by the Holder for all Registrable Securities then held
by the Holder for each thirty (30) day period, pro rated for any period less
than thirty (30) days (except with respect to the Registration Statement not
being declared effective by the Effectiveness Date pursuant to clause (i) of
this Section 7(d)), following the Event until the applicable Event has been
cured. Notwithstanding anything in the foregoing to the contrary, in the event
that the Commission has notified the Company that the Registration Statement
will not be "reviewed" or subject to further review and the Company determines
that it cannot request acceleration of the Registration Statement because the
Company is required to disclose certain material, non-public information, then
Liquidated Damages shall not accrue for a period of forty-five (45) days
following the fifth (5th) Business Day after which the Company had received such
notice from the Commission. The combined aggregate Liquidated Damages payable by
the Company for delayed filing of the registration statement or delayed
effectiveness beyond the Effectiveness Date shall not exceed sixteen percent
(16%) of the purchase price paid by the Purchaser for the Registrable Securities
and Liquidated Damages shall cease to accrue after the date on which Purchaser
would be able to sell all such Registrable Securities held by it without
restriction pursuant to Rule 144(k) promulgated under the Securities Act.
Payments to be made pursuant to this Section 7(d) shall be due and payable
immediately upon demand at the option of the Holders in cash. The parties agree
that the Liquidated Damages represent 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 and maintained in the manner contemplated herein
during the Effectiveness Period or if any other Event as described herein has
occurred.

                  (e) Consent to Jurisdiction.

                           (i) Both the Company and the Purchaser (i) hereby
irrevocably submit 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 or the Purchase Agreement and

                                       13
<PAGE>

(ii) hereby waive, and agree 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. Both the
Company and the Purchaser consent 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 and notice thereof. Nothing in
this Section 7(e) shall affect or limit any right to serve process in any other
manner permitted by law.

                  (f) 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 the Purchaser.

                  (g) 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 such notice or communication is delivered via facsimile at the
facsimile telephone number specified for notice prior to 5:00 p.m., eastern
standard time, on a Business Day, (ii) the first Business Day after the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified for notice later than 5:00 p.m., eastern
time, on any date and earlier than 11:59 p.m., eastern time, on such date, (iii)
the Business Day following the date of mailing, if sent by nationally recognized
overnight courier service or (iv) actual receipt by the party to whom such
notice is required to be given.

or to such other address or addresses or facsimile number or numbers as any such
party may most recently have designated in writing to the other parties hereto
by such notice.

                  (h) Successors and Assigns. This Agreement shall be binding
upon and inure to the benefit of the parties and their successors and permitted
assigns and shall inure to the benefit of the Holder and its successors and
assigns. Except in accordance with Section 7(i) below, neither the Purchaser nor
the Company may assign this Agreement or any of its respective rights or
obligations hereunder without the prior written consent of the other party.

                  (i) Assignment of Registration Rights. The rights of the
Holder hereunder, including the right to have the Company register for resale
Registrable Securities in accordance with the terms of this Agreement, shall be
assignable by each Holder to any transferee of the Holder of all or a portion of
the shares of Registrable Securities if: (i) 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, (ii)
the Company is, within a reasonable time after such transfer or assignment,
furnished with written notice of (a) the name and address of such transferee or
assignee, and (b) the securities with respect to which such registration rights
are being transferred or assigned, (iii) following such transfer or assignment
the further disposition of such securities by the transferee or assignees is
restricted under the Securities Act and applicable state securities laws, (iv)
at or before the time the Company receives the written notice contemplated by
clause (ii) of this Section, the transferee or assignee agrees in writing with
the Company to be bound by all of the provisions of this Agreement, and (v) such
transfer shall have been made in accordance with the applicable requirements of
the Purchase Agreement and shall be for no less than 50% of the Registrable
Securities. In addition, the Holder shall have the right to assign its rights
hereunder to any other Person with the prior written consent of the Company,
which consent shall not be unreasonably withheld. The rights to assignment shall
apply to the Holder (and to subsequent) successors and

                                       15
<PAGE>

assigns. In the event of an assignment pursuant to this Section 7(i), the
Purchaser shall pay all incremental costs and expenses incurred by the Company
in connection with filing a Registration Statement (or an amendment to the
Registration Statement) to register the shares of Registrable Securities
assigned to any assignee or transferee of the Purchaser.

                  (j) 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.

                  (k) Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without regard
to principles of conflicts of law thereof. This Agreement shall not be
interpreted or construed with any presumption against the party causing this
Agreement to be drafted.

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

                  (m) Termination. This Agreement shall terminate on the date on
which all remaining Registrable Securities may be sold without restriction
pursuant to Rule 144(k) of the Securities Act.

                  (n) Severability. If any term, provision, covenant or
restriction of this Agreement is held to be invalid, illegal, void or
unenforceable in any respect, 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.

                  (o) Headings. The headings herein are for convenience only, do
not constitute a part of this Agreement and shall not be deemed to limit or
affect any of the provisions hereof.
