              2. Registration

              (A) FILING AND EFFECTIVENESS OF REGISTRATION STATEMENT. The
Company shall prepare and file with the Commission as soon as practicable a
Registration Statement relating to the offer and sale of the Registrable
Securities and shall use its best efforts to cause the Commission to declare
such Registration Statement effective under the Securities Act as promptly as
practicable but in no event later than the Deadline (as defined in the
Debenture). The Company shall promptly (and, in any event, no more than 24 hours
after it receives comments from the Commission), notify the Buyer when and if it
receives any comments from the Commission on the Registration Statement and
promptly forward a copy of such comments, if they are in writing, to the Buyer.
At such time after the filing of the Registration Statement pursuant to this
Section 2(A) as the Commission indicates, either orally or in writing, that it
has no further comments with respect to such Registration Statement or that it
is willing to entertain appropriate requests for acceleration of effectiveness
of such Registration Statement, the Company shall promptly, and in no event
later than two (2) business days after receipt of such indication from the
Commission, request that the effectiveness of such Registration Statement be
accelerated within forty-eight (48) hours of the Commission's receipt of such
request. The Company shall notify the Initial Investor by written notice that
such Registration Statement has been declared effective by the Commission within
24 hours of such declaration by the Commission.

              (B) ELIGIBILITY FOR USE OF FORM S-3 OR AN SB-2. The Company agrees
that at such time as it meets all the requirements for the use of Securities Act
Registration Statement on Form S-3 or SB-2 and it shall file all reports and
information required to be filed by it with the Commission in a timely manner
and take all such other action so as to maintain such eligibility for the use of
such form.

              (C) ADDITIONAL REGISTRATION STATEMENT. In the event the Current
Market Price declines to a price per share the result of which is that the
Company cannot satisfy its conversion obligations to Initial Investor hereunder,
the Company shall, to the extent required by the Securities Act (because the
additional shares were not covered by the Registration Statement filed pursuant
to Section 2(a)), as reasonably determined by the Initial Investor, file an
additional Registration Statement with the Commission for such additional number
of Registrable Securities as would be issuable upon conversion of the Debenture
(the "ADDITIONAL REGISTRABLE SECURITIES") in addition to those previously
registered. The Company shall, to the extent required by the Securities Act, as
reasonably determined by the Initial Investor, prepare and file with the
Commission not later than the 30th day thereafter, a Registration Statement
relating to the offer and sale of such Additional Registrable Securities and
shall use its best efforts to cause the Commission to declare such Registration
Statement effective under the Securities Act as promptly as practicable but not
later than the Deadline. The Company shall not include any other securities in
the Registration Statement relating to the offer and sale of such Additional
Registrable Securities.


                                       3
<PAGE>

              (D) (i) If the Company proposes to register any of its warrants,
Common Stock or any other shares of common stock of the Company under the
Securities Act (other than a registration (A) on Form S-8 or S-4 or any
successor or similar forms, (B) relating to Common Stock or any other shares of
common stock of the Company issuable upon exercise of employee share options or
in connection with any employee benefit or similar plan of the Company or (C) in
connection with a direct or indirect acquisition by the Company of another
Person or any transaction with respect to which Rule 145 (or any successor
provision) under the Securities Act applies), whether or not for sale for its
own account, it will each such time, give prompt written notice at least 20 days
prior to the anticipated filing date of the registration statement relating to
such registration to each Investor, which notice shall set forth such Investor's
rights under this Section 2(D) and shall offer such Investor the opportunity to
include in such registration statement such number of Registrable Securities as
such Investor may request. Upon the written request of any Investor made within
10 days after the receipt of notice from the Company (which request shall
specify the number of Registrable Securities intended to be disposed of by such
Investor), the Company will use its best efforts to effect the registration
under the Securities Act of all Registrable Securities that the Company has been
so requested to register by each Investor, to the extent requisite to permit the
disposition of the Registrable Securities so to be registered; provided,
however, that (A) if such registration involves a Public Offering, each Investor
must sell its Registrable Securities to any underwriters selected by the Company
with the consent of such Investor on the same terms and conditions as apply to
the Company and (B) if, at any time after giving written notice of its intention
to register any Registrable Securities pursuant to this Section 2 and prior to
the effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason not to register such
Registrable Securities, the Company shall give written notice to each Investor
and, thereupon, shall be relieved of its obligation to register any Registrable
Securities in connection with such registration. The Company's obligations under
this Section 2(D) shall terminate on the date that the registration statement to
be filed in accordance with Section 2(A) is declared effective by the
Commission.

              (ii) If a registration pursuant to this Section 2(D) involves a
Public Offering and the managing underwriter thereof advises the Company that,
in its view, the number of shares of Common Stock that the Company and the
Investors intend to include in such registration exceeds the largest number of
shares of Common Stock that can be sold without having an adverse effect on such
Public Offering (the "MAXIMUM OFFERING SIZE"), the Company will include in such
registration only such number of shares of Common Stock as does not exceed the
Maximum Offering Size, and the number of shares in the Maximum Offering Size
shall be allocated among the Company, the Investors and any other sellers of
Common Stock in such Public Offering ("THIRD-PARTY SELLERS"), FIRST, pro rata
among the Investors until all the shares of Common Stock originally proposed to
be offered for sale by the Investors have been allocated, and SECOND, pro rata
among the Company and any Third-Party Sellers, in each case on the basis of the
relative number of shares of Common Stock originally proposed to be offered for
sale under such registration by each of the Investors, the Company and the
Third-Party Sellers, as the case may be. If as a result of the proration
provisions of this Section 2(D)(ii), any Investor is not entitled to include all
such Registrable Securities in such registration, such Investor may elect to
withdraw its request to include any Registrable Securities in such registration.
With respect to registrations pursuant to this Section 2(D), the number of
securities required to satisfy any underwriters' over-allotment option shall be
allocated among the Company, the Investors and any Third Party Seller pro rata
on the basis of the relative number of securities offered for sale under such
registration by each of the Investors, the Company and any such Third Party
Sellers before the exercise of such over-allotment option.

thereof to be current and useable by Investors for resales of the Registrable
Securities for a period of five (5) years from the date on which the
Registration Statement is first declared effective by the Commission (the
"EFFECTIVE TIME") or such shorter period that will terminate when all the
Registrable Securities covered by the Registration Statement have been sold
pursuant thereto in accordance with the plan of distribution provided in the
Prospectus, transferred pursuant to Rule 144 under the Securities Act or
otherwise transferred in a manner that results in the delivery of new securities
not subject to transfer restrictions under the Securities Act (the "REGISTRATION
PERIOD") 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, not misleading
and (B) the Prospectus forming part of the Registration Statement, and any
amendment or supplement thereto, does not at any time during the Registration
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) During the Registration Period, comply with the provisions of

such number of copies of the Prospectus and all amendments and supplements
thereto and such other documents, as such Investor may reasonably request in
order to facilitate the disposition of the Registrable Securities owned by such

supplements to such registrations and qualifications as may be necessary to
maintain the effectiveness thereof at all times during the Registration Period,
(iii) take all such other lawful actions as may be necessary to maintain such
registrations and qualifications in effect at all times during the Registration

jurisdiction where it would not otherwise be required to qualify but for this
Section 3(D), (B) subject itself to general taxation in any such jurisdiction or

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, in
light of the circumstances under which they were made, not misleading, and
promptly prepare an amendment to the Registration Statement and supplement to
the Prospectus to correct such untrue statement or omission, and deliver a
number of copies of such supplement and amendment to each Investor as such
Investor may reasonably request;

              (F) As promptly as practicable after becoming aware of such event,

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;

proprietary or containing any material nonpublic information shall be kept
confidential by such Investors and any such underwriter, attorney, accountant or

be, included in the Registration Statement), addressed to each underwriter
participating in such underwritten offering (if such underwriter has provided
such letter, representations or documentation, if any, required for such cold
comfort letter to be so addressed), in customary form and covering matters of
the type customarily covered in "cold comfort" letters in connection with
secondary underwritten offerings;

              (Q) In connection with any underwritten offering, deliver such
documents and certificates as may be reasonably required by the managers, if

"NASD RULES") (or any successor provision thereto)) of the Company or has a
"CONFLICT OF INTEREST" (as defined in Rule 2720(b)(7) of the NASD Rules (or any
successor provision thereto)) and such broker-dealer shall underwrite,
participate as a member of an underwriting syndicate or selling group or assist
in the distribution of any Registrable Securities covered by the Registration
Statement, whether as a holder of such Registrable Securities or as an
underwriter, a placement or sales agent or a broker or dealer in respect
thereof, or otherwise, the Company shall assist such broker-dealer in complying
with the requirements of the NASD Rules, including, without limitation, by (A)

Company to complete the registration pursuant to this Agreement with respect to
the Registrable Securities of a particular Investor that such Investor shall

<PAGE>

              (B) Each Investor by its acceptance of the Registrable Securities
agrees to cooperate with the Company in connection with the preparation and
filing of the Registration Statement hereunder, unless such Investor has
notified the Company in writing of its election to exclude all of its
Registrable Securities from the Registration Statement; and

              (C) Each Investor agrees that, upon receipt of any notice from the
Company of the occurrence of any event of the kind described in Section 3(E) or
3(F), it shall immediately discontinue its disposition of Registrable Securities

Prospectus contemplated by Section 3(E) and, if so directed by the Company, such
Investor shall deliver to the Company (at the expense of the Company) or destroy
(and deliver to the Company a certificate of destruction) all copies in such
Investor's possession, of the Prospectus covering such Registrable Securities
current at the time of receipt of such notice.

              5. Expenses of Registration

and directors and each person who controls such Investor or underwriter within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act (each such person being sometimes hereinafter referred to as an "INDEMNIFIED
PERSON") from and against any losses, claims, damages or liabilities, joint or
several, to which such Indemnified Person may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or

<PAGE>

claim, damage or liability arises out of or is based upon (i) an untrue
statement or alleged untrue statement made in, or an omission or alleged
omission from, such Registration Statement or Prospectus in reliance upon and in
conformity with written information furnished to the Company by such Indemnified
Person expressly for use therein or (ii) in the case of the occurrence of an
event of the type specified in Section 3(E), the use by the Indemnified Person
of an outdated or defective Prospectus after the Company has provided to such
Indemnified Person an updated Prospectus correcting the untrue statement or
alleged untrue statement or omission or alleged omission giving rise to such
loss, claim, damage or liability.

              (B) NOTICE OF CLAIMS, ETC. Promptly after receipt by a party
seeking indemnification pursuant to this Section 6 (an "INDEMNIFIED PARTY") of
written notice of any investigation, claim, proceeding or other action in
respect of which indemnification is being sought (each, a "CLAIM"), the
Indemnified Party promptly shall notify the party against whom indemnification
pursuant to this Section 6 is being sought (the "INDEMNIFYING PARTY") of the
commencement thereof; but the omission to so notify the Indemnifying Party shall
not relieve it from any liability that it otherwise may have to the Indemnified
Party, except to the extent that the Indemnifying Party is materially prejudiced
and forfeits substantive rights and defenses by reason of such failure. In
connection with any Claim as to which both the Indemnifying Party and the
Indemnified Party are parties, the Indemnifying Party shall be entitled to
assume the defense thereof. Notwithstanding the assumption of the defense of any
Claim by the Indemnifying Party, the Indemnified Party shall have the right to
employ separate legal counsel and to participate in the defense of such Claim,
and the Indemnifying Party shall bear the reasonable fees, out-of-pocket costs
and expenses of such separate legal counsel to the Indemnified Party if (and
only if): (x) the Indemnifying Party shall have agreed to pay such fees, costs
and expenses, (y) the Indemnified Party and the Indemnifying Party shall
reasonably have concluded that representation of the Indemnified Party by the
Indemnifying Party by the same legal counsel would not be appropriate due to
actual or, as reasonably determined by legal counsel to the Indemnified Party,
potentially differing interests between such parties in the conduct of the
defense of such Claim, or if there may be legal defenses available to the
Indemnified Party that are in addition to or disparate from those available to
the Indemnifying Party or (z) the Indemnifying Party shall have failed to employ
legal counsel reasonably satisfactory to the Indemnified Party within a
reasonable period of time after notice of the commencement of such Claim. If the
Indemnified Party employs separate legal counsel in circumstances other than as
described in clauses (x), (y) or (z) above, the fees, costs and expenses of such
legal counsel shall be borne exclusively by the Indemnified Party. Except as
provided above, the Indemnifying Party shall not, in connection with any Claim
in the same jurisdiction, be liable for the fees and expenses of more than one
firm of counsel for the Indemnified Party (together with appropriate local
counsel). The Indemnified Party shall not, without the prior written consent of
the Indemnifying Party (which consent shall not unreasonably be withheld),
settle or compromise any Claim or consent to the entry of any judgment that does
not include an unconditional release of the Indemnifying Party from all
liabilities with respect to such Claim or judgment.

              (C) CONTRIBUTION. If the indemnification provided for in this
Section 6 is unavailable to or insufficient to hold harmless an Indemnified
Person under subsection (A) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
Indemnifying Party shall contribute to the amount paid or payable by such
Indemnified Party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative fault of the Indemnifying Party and the Indemnified Party in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative fault of such Indemnifying Party and


                                       10
<PAGE>

Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by
such Indemnifying Party or by such Indemnified Party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The parties hereto agree that it would not be just
and equitable if contribution pursuant to this Section 6(D) were determined by
pro rata allocation (even if the Investors or any underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in this Section 6(D).
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
shall be deemed to include any legal or other fees or expenses reasonably
incurred by such Indemnified Party in connection with investigating or defending
any such action or claim. 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 obligations of the Investors and any underwriters in this
Section 6(D) to contribute shall be several in proportion to the percentage of
Registrable Securities registered or underwritten, as the case may be, by them
and not joint.

              (D) Notwithstanding any other provision of this Section 6, in no
event shall any (i) Investor be required to undertake liability to any person
under this Section 6 for any amounts in excess of the dollar amount of the
proceeds to be received by such Investor from the sale of such Investor's
Registrable Securities (after deducting any fees, discounts and commissions
applicable thereto) pursuant to any Registration Statement under which such
Registrable Securities are to be registered under the Securities Act and (ii)
underwriter be required to undertake liability to any Person hereunder for any
amounts in excess of the aggregate discount, commission or other compensation
payable to such underwriter with respect to the Registrable Securities
underwritten by it and distributed pursuant to the Registration Statement.

              (E) The obligations of the Company under this Section 6 shall be
in addition to any liability which the Company may otherwise have to any
Indemnified Person and the obligations of any Indemnified Person under this
Section 6 shall be in addition to any liability which such Indemnified Person
may otherwise have to the Company. The remedies provided in this Section 6 are
not exclusive and shall not limit any rights or remedies which may otherwise be
available to an indemnified party at law or in equity.

              7. Rule 144

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

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


                                       11
<PAGE>

              (2) file with the Commission in a timely manner all reports and
other documents required to be filed by the Company pursuant to Section 13 or
15(d) under the Exchange Act; and, if at any time it is not required to file
such reports but in the past had been required to or did file such reports, it
will, upon the request of any Investor, make available other information as
required by, and so long as necessary to permit sales of, its Registrable
Securities pursuant to Rule 144.

              8. Assignment

              The rights to have the Company register Registrable Securities
pursuant to this Agreement shall be automatically assigned by the Investors to
any permitted transferee of all or any portion of such Registrable Securities
(or all or any portion of the Debenture or Warrant of the Company which is
convertible into such securities) only if (a) the Investor agrees in writing
with the transferee or assignee to assign such rights, and a copy of such
agreement is furnished to the Company within a reasonable time after such
assignment, (b) the Company is, within a reasonable time after such transfer or
assignment, furnished with written notice of (i) the name and address of such
transferee or assignee and (ii) the securities with respect to which such
registration rights are being transferred or assigned, (c) immediately following
such transfer or assignment, the securities so transferred or assigned to the
transferee or assignee constitute Restricted Securities and (d) at or before the
time the Company received the written notice contemplated by clause (b) of this
sentence the transferee or assignee agrees in writing with the Company to be
bound by all of the provisions contained herein.

              9. Amendment and Waiver

              Any provision of this Agreement may be amended and the observance
thereof may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the Company
and Investors who hold a majority-in-interest of the Registrable Securities. Any
amendment or waiver effected in accordance with this Section 9 shall be binding
upon each Investor and the Company.

              10. Changes in Common Stock

              If, and as often as, there are any changes in the Common Stock by
way of stock split, stock dividend, reverse split, combination or
reclassification, or through merger, consolidation, reorganization or
recapitalization, or by any other means, appropriate adjustment shall be made in
the provisions hereof, as may be required, so that the rights and privileges
granted hereby shall continue with respect to the Common Stock as so changed.

              11. Miscellaneous

              (A) A person or entity shall be deemed to be a holder of
Registrable Securities whenever such person or entity owns of record such
Registrable Securities. If the Company receives conflicting instructions,
notices or elections from two or more persons or entities with respect to the
same Registrable Securities, the Company shall act upon the basis of
instructions, notice or election received from the registered owner of such
Registrable Securities.

              (B) If, after the date hereof and prior to the Commission
declaring the Registration Statement to be filed pursuant to Section 2(a)
effective under the Securities Act, the Company grants to any Person any
registration rights with respect to any Company securities which are more
favorable to such other Person than those provided in this Agreement, then the
Company forthwith shall grant (by means of an amendment to this Agreement or
otherwise) identical registration rights to all Investors hereunder.

              (C) Except as may be otherwise provided herein, any notice or
other communication or delivery required or permitted hereunder shall be in
writing and shall be delivered personally, or sent by telecopier machine or by a
nationally recognized overnight courier service, and shall be deemed given when
so delivered personally, or by telecopier machine or overnight courier service
as follows:

                 (1)   if to the Company, to:

                       One Voice Technologies, Inc.
                       6333 Greenwich Drive, Suite 240
                       San Diego, CA 92122
                       Telephone:       858-552-4466
                       Facsimile:       858-552-4474


                 (2)   if to the Buyer, to:

                       La Jolla Cove Investors, Inc.
                       7817 Herschel Avenue, Suite 200
                       La Jolla, California 92037
                       Telephone:       858-551-8789
                       Facsimile:       858-551-8779


                            (3) if to any other Investor, at such address as
         such Investor shall have provided in writing to the Company.

The Company, the Initial Investor or any Investor may change the foregoing
address by notice given pursuant to this Section 11(C).

              (D) Failure of any party to exercise any right or remedy under
this Agreement or otherwise, or delay by a party in exercising such right or
remedy, shall not operate as a waiver thereof.

              (E) This Agreement shall be governed by and interpreted in
accordance with the laws of the State of California. Each of the parties
consents to the jurisdiction of the federal courts whose districts encompass any
part of the City of San Diego or the state courts of the State of California
sitting in the City of San Diego in connection with any dispute arising under
this Agreement and hereby waives, to the maximum extent permitted by law, any
objection including any objection based on forum non conveniens, to the bringing
of any such proceeding in such jurisdictions.

              (F) Should any party hereto employ an attorney for the purpose of
enforcing or construing this Agreement, or any judgment based on this Agreement,
in any legal proceeding whatsoever, including insolvency, bankruptcy,
arbitration, declaratory relief or other litigation, the prevailing party shall
be entitled to receive from the other party or parties thereto reimbursement for
all reasonable attorneys' fees and all reasonable costs, including but not

                                       13
<PAGE>

limited to service of process, filing fees, court and court reporter costs,
investigative costs, expert witness fees, and the cost of any bonds, whether
taxable or not, and that such reimbursement shall be included in any judgment or
final order issued in that proceeding. The "prevailing party" means the party
determined by the court to most nearly prevail and not necessarily the one in
whose favor a judgment is rendered.

              (G) The remedies provided in this Agreement are cumulative and not
exclusive of any remedies provided by law. 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. 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.

              (H) Except as disclosed in the Schedules to the Securities
Purchase Agreement dated December 12, 2003, 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
conflicts with the provisions hereof. The Company is not currently a party to
any agreement granting any registration rights with respect to any of its
securities to any person which conflicts with the Company's obligations
hereunder or gives any other party the right to include any securities in any
Registration Statement filed pursuant hereto, except for such rights and
conflicts as have been irrevocably waived. Without limiting the generality of
the foregoing, without the written consent of the holders of a majority in
interest of the Registrable Securities, the Company shall not grant to any
person the right to request it to register any of its securities under the
Securities Act unless the rights so granted are subject in all respect to the
prior rights of the holders of Registrable Securities set forth herein, and are
not otherwise in conflict or inconsistent with the provisions of this Agreement.
The restrictions on the Company's rights to grant registration rights under this
paragraph shall terminate on the date the Registration Statement to be filed
pursuant to Section 2(A) is declared effective by the Commission.

              (I) This Agreement, the Securities Purchase Agreement, the
Debenture and the Conversion Warrants Agreement, of even date herewith among the
Company and the Initial Investor constitute the entire agreement among the
parties hereto with respect to the subject matter hereof. There are no
restrictions, promises, warranties or undertakings, other than those set forth
or referred to herein. These Agreements supersede all prior agreements and
undertakings among the parties hereto with respect to the subject matter hereof.

              (J) Subject to the requirements of Section 8 hereof, this
Agreement shall inure to the benefit of and be binding upon the successors and
assigns of each of the parties hereto.

              (K) All pronouns and any variations thereof refer to the
masculine, feminine or neuter, singular or plural, as the context may require.


                                       14
<PAGE>

              (L) The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning thereof.

              (M) The Company acknowledges that any failure by the Company to
perform its obligations under Section 3, or any delay in such performance, could
result in direct damages to the Investors and the Company agrees that, in
addition to any other liability the Company may have by reason of any such
failure or delay, the Company shall be liable for all direct damages caused by
such failure or delay.

              (N) This Agreement may be executed in counterparts, each of which
shall be deemed an original but both of which shall constitute one and the same
agreement. A facsimile transmission of this signed Agreement shall be legal and
binding on the parties hereto.

         IN WITNESS WHEREOF, the parties hereto have duly caused this Agreement
to be executed and delivered on the date first above written.
