EXHIBIT 2.15

                          REGISTRATION RIGHTS AGREEMENT

                  THIS REGISTRATION RIGHTS AGREEMENT (the "Agreement"), dated ,
2003, is between North American Mortgage and Finance Corporation (the
"Investor"), and Consolidated Water Co. Ltd., a Cayman Islands Company (the
"Company").

                                    RECITALS

         A.       Simultaneously with the execution and delivery of this
Agreement, the Investor is acquiring from the Company, pursuant to a Share Sale
Agreement dated the date hereof (the "SSA"), 185,174 ordinary shares ("Ordinary
Shares") of CI$1.00 par value (the "Securities") (terms not defined herein shall
have the meanings ascribed to them in the SSA).

         B.       The Company desires to grant to the Investor the registration
rights set forth herein with respect to the Securities acquired pursuant to the
SSA.

         NOW, THEREFORE, the parties hereto mutually agree as follows:

         Section 1.        Registrable Securities. As used herein the term
"Registrable Security" means the Securities until (i) the Registration Statement
has been declared effective by the Commission (as defined below), and all
Securities have been disposed of pursuant to the Registration Statement, (ii)
all Securities have been sold under circumstances under which all of the
applicable conditions of Rule 144 as it may be amended from time to time or any
similar provision then in effect ("Rule 144") under the Securities Act of 1933
(the "Securities Act") are met, (iii) all Securities have been otherwise
transferred to holders who may trade such Securities without restriction under
the Securities Act, and the Company has delivered a new certificate or other
evidence of ownership for such Securities not bearing a restrictive legend or
(iv) such time as, in the opinion of counsel to the Company, all Securities may
be sold without any time, volume or manner of sale limitations pursuant to Rule
144(k) (or any similar provision then in effect) under the Securities Act and
the Company has delivered a new certificate or other evidence of ownership for
such securities not bearing a restrictive legend. The term "Registrable
Securities" means any and/or all of the securities falling within the foregoing
definition of a "Registrable Security." In the event of any merger,
reorganization, consolidation, recapitalization or other change in corporate
structure affecting the Ordinary Shares of the Company, such adjustment shall be
deemed to be made in the definition of "Registrable Security" as is appropriate
in order to prevent any dilution or enlargement of the rights granted pursuant
to this Agreement.

         Section 2.        Restrictions on Transfer. The Investor acknowledges
and understands that prior to the registration of the Securities as provided
herein, the Securities are "restricted securities" as defined in Rule 144
promulgated under the Securities Act. The Investor understands that no
disposition or transfer of the Securities may be made by an Investor in the
absence of (i) an opinion of counsel to an Investor, in form and substance
reasonably satisfactory to the Company, that such transfer may be

                                      -1-

made without registration under the Securities Act, pursuant to Regulation D or
another exemption, or (ii) such registration.

                  With a view to making available to the Investor the benefits
of Rule 144 under the Securities Act or any other similar rule or regulation of
the Securities and Exchange Commission (the "Commission") that may at any time
permit the Investor to sell securities of the Company to the public without
registration, the Company agrees to:

                  (a)      comply with the provisions of paragraph (c) (1) of
Rule 144; and

                  (b)      file with the Commission in a timely manner all
reports and other documents required to be filed with the Commission pursuant to
Section 13 or 15(d) under the Securities Exchange Act of 1934 (the "Exchange
Act") by companies subject to either of such sections, irrespective of whether
the Company is then subject to such reporting requirements.

         SECTION 3.        REGISTRATION RIGHTS WITH RESPECT TO THE SECURITIES.
1.

                  (a)      By the earlier to occur of (i) sixty (60) calendar
days after the date that the Company's registration statement (the "Company
Registration Statement") for its contemplated underwritten public offering is
declared effective by the Commission or (ii) June 30, 2003, (the "Filing
Deadline Date"), the Company will prepare and file a Registration Statement with
the Commission, at the sole expense of the Company (except as provided in
Section 3(c) hereof), so as to permit a public offering and resale of the
Securities under the Securities Act by the Investor as a selling shareholder.

         For the purposes of this Agreement, "Registration Statement" means any
registration statement of the Company which registers for sale under the
Securities Act any of the Registrable Securities, including the Prospectus, all
amendments and supplements to such Registration Statement including
post-effective amendments, all financial statements of the Company included
therein, all exhibits to such Registration Statement, and all material
incorporated by reference in such Registration Statement. The term "Prospectus"
shall mean the prospectus included in any Registration Statement, as amended or
supplemented by any prospectus supplement with respect to the terms of the
offering of any of the Registrable Securities and all other amendments or
supplements to the Prospectus, including post-effective amendments, and all
material incorporated by reference in such Registration Statement.

         The Company shall use its best efforts to cause such Registration
Statement to become effective within ninety (90) calendar days from the Filing
Deadline Date, or, if earlier, within five (5) days of the Commission's
clearance in response to the Company's request for acceleration of the
effectiveness of the Registration Statement (in either case the "Effectiveness
Deadline Date"). In the event that the registration of Registrable Securities is
underwritten, the Company shall enter into an underwriting agreement in

                                      -2-

usual and customary form. The Company will notify the Investor of the
effectiveness of the Registration Statement within two calendar days of such
event.

         Notwithstanding any provisions contained in this Agreement to the
contrary, the Investor shall not offer for sale or sell, transfer or otherwise
dispose of the Registrable Securities in violation of Section 10 hereof.

                  (b)      The Company will maintain the effectiveness under the
Securities Act of the Registration Statement or post-effective amendment filed
under this Section 3 until the earliest of (i) the date that none of the
Securities covered by such Registration Statement are or may become issued and
outstanding, (ii) the date that all of the Securities have been sold pursuant to
such Registration Statement, (iii) two (2) years from the date of the closing of
the SSA, (iv) the date on which all Securities have been otherwise transferred
to persons who may trade such shares without restriction under the Securities
Act, and the Company has delivered a new certificate or other evidence of
ownership for such securities not bearing a restrictive legend, or (v) the first
date upon which, in the opinion of counsel to the Company, which counsel shall
be reasonably acceptable to the Investor all Securities may be sold without any
time, volume or manner of sale limitations pursuant to Rule 144(k) or any
similar provision then in effect under the Securities Act (the "Effectiveness
Period").

                  (c)      The Company shall bear all fees, disbursements and
out-of-pocket expenses and costs incident to the performance of its obligations
under this Agreement including (i) the preparation, filing and printing of the
Registration Statement under subparagraph 3(a) as originally filed and as
amended, any preliminary prospectuses and the Prospectus and any amendments or
supplements thereto, (ii) the fees and disbursements of counsel for the Company
and the fees and disbursements of accountants for the Company; (iii) the
preparation, printing and distribution of any underwriting or agency agreement,
certificates representing the Securities (if any), any Blue Sky Survey and other
documents relating to the performance of and compliance by the Company with this
Agreement; (iv) the fees and disbursements of the underwriters or agents
customarily paid by issuers or sellers of securities, the fees of their
respective counsel, and the fees and disbursements of any experts retained in
connection with such Registration Statement (but excluding underwriting
discounts and commissions and transfer taxes, if any, as described below); (v)
the costs of the qualification of the Securities under applicable state
securities and Blue Sky laws and the costs and expenses associated with any
filing required to be made with the National Association of Securities Dealers,
Inc; (vi) all fees and expenses incurred in connection with the listing of the
Securities on any securities exchange and the fees of any transfer agent,
registrar or depository for the securities; and (vii) expenses for the
duplication and delivery to the Investor of copies of the Registration Statement
and the Prospectus forming part thereof and any other related documents as
provided in Sections 5(h) and 5 (i) below. The Investor shall bear the cost of
underwriting and/or brokerage discounts, and commissions, if any, applicable to
the Securities being registered, the costs and expenses (if any) incident to the
delivery of the Registrable Securities to be sold by it, including any transfer
taxes payable in connection with such sale.

                                      -3-

                  (d)      In connection with the preparation and filing of the
Registration Statement the Company shall provide to the Investor and its counsel
and accountants the opportunity to review and comment upon, for a period not to
exceed five (5) business days, the Registration Statement and any amendments
thereto prior to filing with the Commission. The Company shall provide the
Investor with copies of any comment letters received from the Commission with
respect thereto within two (2) calendar days of receipt thereof. For purposes of
this Agreement, a business day means any day that is not a Saturday or Sunday
and on which banks are open for the conduct of normal business in New York City,
New York, Grand Cayman, Cayman Islands, B.W.I., and London, England.

                  (e)      The Company shall afford the Investor, its counsel
and its accountants the opportunity to review its books and records and to
discuss the business of the Company with its officers and the independent public
accountants who have certified the Company's financial statements to permit the
Investor and its counsel and accountants to conduct, in their view, a reasonable
investigation as may be necessary to comply with the requirements of the
Securities Act. All fees and expenses of the Investor's counsel, accountants and
other representatives relating to such investigation shall be paid by the
Investor. The Company shall qualify any of the securities for sale in such
states as the Investor reasonably designates and shall furnish indemnification
in the manner provided in Section 6 hereof. However, the Company shall not be
required to qualify in any state which will require an escrow or other
restriction relating to the Company and/or the sellers, or which will require
the Company to qualify to do business in such state or require the Company to
file therein any general consent to service of process (as opposed to a specific
consent for purposes of actions under applicable state securities laws).

                  (f)      The Company shall not be required by this Section 3
to include the Investor's Securities in any Registration Statement which is to
be filed if, in the opinion of counsel for the Investor and the Company (or,
should they not agree, in the opinion of another counsel experienced in
securities law matters acceptable to counsel for the Investor and the Company,
which counsel's fees and expenses shall be shared equally by the Investor and
the Company) the proposed offering or other transfer as to which such
registration is requested is exempt from applicable federal and state securities
laws and would result in all purchasers or transferees obtaining securities
which are not "restricted securities", as defined in Rule 144 under the
Securities Act.

                  (g)      If at any time after the effective date of any
Registration Statement, the Company notifies the Investor in writing of (i) the
issuance by the Commission of a stop order suspending the effectiveness of the
Registration Statement or the initiation of proceedings with respect to the
Registration Statement under Section 8 (d) or 8 (e) of the Securities Act or
(ii) the existence of a Potential Material Event (as defined in Section 3(h)
below), the Investor shall not offer or sell any Securities or engage in any
other transaction involving or relating to Securities (a "Blackout Period"),
from the time of the giving of notice with respect to a stop order or Potential
Material Event until the Investor receives written notice from the Company that
either (x) the Registration Statement (as amended or supplemented, if necessary)
may be used and the Investor has received from the Company copies of any amended
or supplemented

                                      -4-

Registration Statement or (y)such Potential Material Event either has been
disclosed to the public or no longer constitutes a Potential Material Event;
provided, however, that the Company may not so suspend the right of the Investor
to transfer Securities for more than forty-five (45) days in the aggregate
during any three month period or for more than ninety (90) days in the aggregate
during any twelve (12) month period, during the Effectiveness Period. If a
Potential Material Event shall occur prior to the date a Registration Statement
is required to be filed, then the Company's obligation to file such Registration
Statement shall be delayed for not more than ninety (90) consecutive calendar
days. The Company must give the Investor notice in writing at least two (2)
calendar days prior to the first day of a Blackout Period.

                  (h)      "Potential Material Event" means any of the
following: (a) the possession by the Company of material information not ripe
for disclosure in a registration statement, as determined in good faith by the
Chief Executive Officer or the Board of Directors of the Company that disclosure
of such information in a Registration Statement would be detrimental to the
business and affairs of the Company; or (b) any material engagement or activity
by the Company which would, in the good faith determination of the Chief
Executive Officer or the Board of Directors of the Company, be adversely
affected by disclosure in a registration statement at such time, which
determination shall be accompanied by a good faith determination by the Chief
Executive Officer or the Board of Directors of the Company that the applicable
Registration Statement would be materially misleading absent the inclusion of
such information

                  (i)      The Company recognizes and agrees that the Investor
will incur damages and will not realize the benefits sought to be conferred on
the Investor under the SSA if the Company fails to comply with its obligations
hereunder to effect and maintain the registration of the Registrable Securities.
Accordingly, the Company expressly agrees that in the event that (i) the
Registration Statement has not been filed on or prior to the Filing Deadline
Date, and (ii) the Registration Statement has not been declared effective under
the Securities Act on or prior to the Effectiveness Deadline Date, or (iii) the
aggregate duration of Blackout Periods during any period exceeds the number of
days permitted in respect of such period pursuant to Section 3(g) hereof (each
of the events of a type described in any of the foregoing clauses (i) through
(iii) being individually referred to herein as an "Event") the Investor shall
have the right to require the Company to purchase from it all the Registrable
Securities held by the Investor at a price per share equal to the greater of (i)
US$14.00 per share (ii) the closing price of the Ordinary Shares on NASDAQ on
the last day on which an Event occurs giving rise to the claim of the Investor
for damages under this Section 3(i). Following the occurrence of such Event, the
Investor shall notify the Company of its claim for damages under this provision
by providing written notice to the Company and within 20 calendar days of the
date of such notice, the Company shall (x) provide to the Investor a written
computation of the damages to be paid pursuant to the formula above and (y) pay
to the Investor in full, without offset or discount, the amount of said damages
as reflected in the Company's computation, via wire transfer of immediately
available funds to a bank account designated to the Company by the Investor. The
Company's payment to the Investor of the damages set forth in this Section 3(i)
shall be the sole and exclusive remedy available to the Investor under this
Agreement and all other applicable laws, and

                                      -5-

upon payment of such damages, the Company shall have no other liability or
obligation whatsoever to the Investor.

         Section 4.        Cooperation with Company. The Investor will cooperate
with the Company in all respects in connection with this Agreement, including
timely supplying all information reasonably requested by the Company (which
shall include all information regarding the Investor and proposed manner of sale
of the Registrable Securities required to be disclosed in any Registration
Statement) and executing and returning all documents reasonably requested in
connection with the registration and sale of the Registrable Securities and
entering into and performing its obligations under any underwriting agreement,
if the offering is an underwritten offering, in usual and customary form, with
the managing underwriter or underwriters of such underwritten offering.

         Section 5.        Registration Procedures. In connection with the
fulfillment by the Company of its obligations hereunder to effect the
registration of the Registrable Securities under the Securities Act, the Company
shall (except as otherwise provided in this Agreement), as expeditiously as
reasonably possible, subject to the Investor's assistance and cooperation as
reasonably required with respect to each Registration Statement:

                  (a)(i)   prepare and file with the Commission such
amendments and supplements to the Registration Statement and the Prospectus used
in connection therewith as may be necessary to keep such Registration Statement
current and effective and to comply with the provisions of the Securities Act

Securities covered by such registration statement whenever the Investor shall
desire to sell or otherwise dispose of the same (including prospectus
supplements with respect to the sales of securities from time to time in
connection with a registration statement pursuant to Rule 415 promulgated under
the Securities Act), and (ii) take all lawful action such that each of (A) the
Registration Statement and any amendment thereto does not, when it becomes
effective, 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, and (B) any preliminary prospectus and any other Prospectus forming
part of the Registration Statement, and any amendment or supplement thereto,
does not at any time during the Effectiveness Period include 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;

                  (b)(i)   prior to the filing with the Commission of any
Registration Statement (including any amendments thereto) and the distribution

copies thereof to the Investor as required by Section 3(c) and reflect in such
documents all such comments as the Investor (and its counsel) reasonably may
propose, and (ii) furnish to the Investor such numbers of copies of the
Registration Statement and the Prospectus (including any preliminary prospectus
or any amendment or supplement to any Prospectus, as applicable), in conformity
with the requirements of the Securities Act, and such other

                                      -6-

Effectiveness Period of the happening of any event of which the Chief Executive
Officer or Chief Financial Officer of the Company becomes aware as a result of
which the Prospectus included in the Registration Statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in the light of the circumstances then existing, and the Company
shall prepare and file a curative amendment under Section 5(a) as quickly as
commercially possible;

                  (f)      as promptly as practicable after becoming aware of
such event, notify the Investor who holds Registrable Securities being sold (or,
in the event of an underwritten offering, the managing underwriters) of the
issuance by the Commission of any stop order or other suspension of the
effectiveness of the Registration Statement at the earliest possible time and
take all lawful action to effect the withdrawal, recession or removal of such
stop order or other suspension;

                  (g)      cooperate with the Investor to facilitate the timely
preparation and delivery of certificates for the Registrable Securities to be

                  (i)      During the Effectiveness Period, deliver to the
Investor in connection with any sale of Registrable Securities pursuant to a

limited to, all reasonable costs of defense, preparation and investigation and
all reasonable attorneys' fees and expenses), to which the Investor may become
subject, under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon (i) any untrue statement or alleged untrue statement of any material fact
contained in any Registration Statement, or any amendment or supplement thereto,
or upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading; (ii) any alleged untrue statement of a material fact included in any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto), or the omission or alleged omission therefrom of a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading; or (iii) any litigation or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever
based upon any such untrue statement or omission or any such untrue statement or
omission or any such alleged untrue statement or omission provided, however,
that the Company will not be liable in any such case to the extent, and only to
the extent, that any such loss, claim, damage or liability arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in such Registration Statement, preliminary prospectus,
final prospectus or amendment or supplement thereto in reliance upon, and in
conformity with, written information furnished to the Company by or on behalf of
the Investor, or its counsel, specifically for use in the preparation thereof
(it being understood that no representation, warranty or other statement by the

information furnished to the Company by the Investor specifically for use in the
preparation of the Registration Statement or any Prospectus for the purposes of
this Agreement). This indemnity agreement will be in addition to any liability
which the Company may otherwise have.

liabilities (which shall, for all purposes of this Agreement, include, but not
be limited to, all reasonable costs of defense, preparation and investigation
and all reasonable attorneys' fees and expenses) to which the Company or any
such officer, director or controlling person may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in any Registration Statement, or amendment or supplement thereto, or upon the
omission or the alleged

                                      -9-

omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading; (ii) any untrue
statement or alleged untrue statement of a material fact included in any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto), or the omission or alleged omission therefrom of a material fact
required to be stated therein or necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; (iii) any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever
based upon any such untrue statement or omission or any such alleged untrue
statement or omission, but in each case only to the extent that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in such Registration Statement, preliminary prospectus, final prospectus or
amendment or supplement thereto in reliance upon, and in conformity with,
written information furnished to the Company by or on behalf of the Investor, or
its counsel, specifically for use in the preparation thereof (it being
understood that no representation, warranty or other statement by the Investor
in the SSA or any related agreement or document (including, without limitation,
the disclosure letters referred to therein) shall be deemed written information
furnished to the Company by the Investor specifically for use in the preparation
of the Registration Statement or any Prospectus for the purposes of the
Agreement). This indemnity agreement will be in addition to any liability which
the Investor may otherwise have.

                  (c)      Promptly after receipt by an indemnified party under
this Section 6 of notice of the commencement of any action against such
indemnified party, such indemnified party will, if a claim in respect thereof is
to be made against the indemnifying party under this Section 6, notify the
indemnifying party in writing of the commencement thereof; but the omission so
to notify the indemnifying party will not relieve the indemnifying party from
any liability which it may have to any indemnified party except to the extent
the failure of the indemnified party to provide such written notification
actually prejudices the ability of the indemnifying party to defend such action.
In case any such action is brought against any indemnified party, and it
notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate in, and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified, assume the defense
thereof, subject to the provisions herein stated. After notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party under this Section 6 for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof other than
reasonable costs of investigation, unless the indemnifying party shall not
pursue the action to its final conclusion. Notwithstanding the foregoing, the
indemnified parties as a group shall have the right to employ one separate
counsel in any such action and to participate in the defense thereof, but the
fees and expenses of such counsel shall not be at the expense of the
indemnifying party if the indemnifying party has assumed the defense of the
action with counsel reasonably satisfactory to the indemnified party unless (i)
the employment of such counsel has been specifically authorized in writing by
the indemnifying party, or (ii) the named parties to any such action (including
any impleaded parties) include both the indemnified party and the indemnifying
party and the indemnified party shall have been advised by its counsel that
there may be one or more legal defenses available to the indemnifying party
different from or in conflict with any

                                      -10-

legal defenses which may be available to the indemnified party or any other
indemnified party (in which case the indemnifying party shall not have the right
to assume the defense of such action on behalf of such indemnified party, it
being understood, however, that the indemnifying party shall, in connection with
any one such action or separate but substantially similar or related actions in
the same jurisdiction arising out of the same general allegations or
circumstances, be liable only for the reasonable fees and expenses of one
separate firm of attorneys for the indemnified party, which firm shall be
designated in writing by the indemnified party). No settlement of any action
against an indemnified party shall be made without the prior written consent of
the indemnified party, which consent shall not be unreasonably withheld so long
as such settlement includes a full release of claims against the indemnified
party.

         Section 7.        Contribution. In order to provide for just and
equitable contribution under the Securities Act in any case in which (i) the
indemnified party makes a claim for indemnification pursuant to Section 6 hereof
but is judicially determined (by the entry of a final judgment or decree by a
court of competent jurisdiction and the expiration of time to appeal or the
denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that the express provisions of
Section 6 hereof provide for indemnification in such case, or (ii) contribution
under the Securities Act may be required on the part of any indemnified party,
then the Company and the Investor shall contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (which shall, for
all purposes of this Agreement, include, but not be limited to, all reasonable
costs of defense, preparation and investigation and all reasonable attorneys'
fees and expenses), in either such case (after contribution from others) on the
basis of relative fault as well as any other relevant equitable considerations.
The relative fault shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company on the one hand or by the Investor on the other hand,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The relative
benefits received by the Company, the Investor and the underwriters (if any)
with respect to the sale of the Registrable Securities pursuant to this
Agreement shall be deemed to be in the same respective proportions that the
proceeds from the offering received by the Company and the Investor and the
underwriting discounts received by the underwriters, in each case as set forth
in the table on the cover page of the applicable Prospectus, bear to the
aggregate public offering price of the Registrable Securities. The Company and
the Investor agree that it would not be just and equitable if contribution
pursuant to this Section 7 were determined by pro rata allocation or by any
other method of allocation which does not take account of the equitable
considerations referred to in this Section 7. The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities (or
actions in respect thereof) referred to above in this Section 7 shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating, preparing or defending any such action
or claim (including any investigation or proceeding by any governmental agency
or body). 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.

                                      -11-

Notwithstanding any other provision of this Section 7, in no event shall the
Investor be required to undertake liability to any person under this Section 7
for any amounts in excess of the dollar amount of the proceeds received by the
Investor from the sale of the Investor's Registrable Securities (after deducting
any fees, discounts and commissions applicable thereto) pursuant to any
Registration Statement under which such Registrable Securities are registered
under the Securities Act.

         Section 8.        Notices. All notices, demands, requests, consents,
approvals, and other communications required or permitted hereunder shall be in
writing and shall be delivered as set forth in the SSA.

         Section 9.        Assignment. This Agreement is binding upon and inures
to the benefit of the parties hereto and their respective heirs, successors and
permitted assigns.

         Section 10.       Lock-Up Restrictions. Until one hundred twenty (120)
calendar days after the date that the Company Registration Statement is declared
effective by the Commission, the Investor will not, without the prior written
consent of the underwriter of such offering, directly or indirectly, sell, offer
for sale, transfer, hypothecate, pledge or otherwise dispose of, pursuant to
Rule 144 or otherwise, the Securities directly or indirectly or beneficially
owned by the Investor.

         Notwithstanding the foregoing, the Investor may sell or otherwise
dispose of the Securities in a privately-negotiated transaction, provided that
(i) the acquiror of such securities agrees in advance in writing with the
underwriter of the Company's contemplated public offering to the restrictions on
transfer of the securities as set forth herein and (ii) the disposition is
otherwise in accordance with the United States securities and other applicable
laws.

         Section 11.       Counterparts/Facsimile. This Agreement may be
executed in two or more counterparts, each of which shall constitute an
original, but all of which, when taken together shall constitute but one and the
same instrument, and shall become effective when one or more counterparts have
been signed by each party hereto and delivered to the other parties. In lieu of
the original, a facsimile transmission or copy of the original shall be as
effective and enforceable as the original.

         Section 12.       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 best 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.

         Section 13.       Conflicting Agreements. The Company shall not enter
into any agreement with respect to its securities that is inconsistent with the
rights granted to the holders of Registrable Securities in this Agreement or
otherwise prevents the Company from complying with all of its obligations
hereunder.

                                      -12-

         Section 14.       Headings. The headings in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

         Section 15.       Governing Law. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York applicable to
contracts made in New York by persons domiciled in New York City and without
regard to its principles of conflicts of laws. Each of the parties (a) consents
to submit itself to the personal jurisdiction of the U.S. federal court for the
Southern District of New York or any New York state court located in the City of
New York in the event any dispute arises out of or relates to this Agreement or
any of the transactions contemplated hereby, (b) agrees that it will not attempt
to deny or defeat such personal jurisdiction by motion or other request for
leave from any such court, including, without limitation, a motion to dismiss on
the grounds of forum non conveniens , (c) agrees it will not bring any action
arising out of or relating to this Agreement or any of the transactions
contemplated by this Agreement in any court other than the U.S. federal court
for the Southern District of New York or any New York State court located in the
City of New York and (d) waives any right to trial by jury with respect to any
legal proceeding arising out of or in connection with this Agreement or the
transactions contemplated hereby.

                  IN WITNESS WHEREOF, the parties hereto have caused this
Registration Rights Agreement to be duly executed, on the day and year first
above written.
