THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE
LAWS, AND NO INTEREST THEREIN MAY BE SOLD, DISTRIBUTED, ASSIGNED, OFFERED,
PLEDGED OR OTHERWISE TRANSFERRED UNLESS THERE IS AN EFFECTIVE REGISTRATION
STATEMENT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS COVERING ANY SUCH
TRANSACTION, OR SUCH TRANSACTION IS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF
SUCH ACT AND LAWS, SUCH COMPLIANCE, AT THE OPTION OF THE CORPORATION, TO BE
EVIDENCED BY AN OPINION OF THE WARRANT HOLDER'S COUNSEL, IN FORM ACCEPTABLE TO
THE CORPORATION, THAT NO VIOLATION OF SUCH REGISTRATION PROVISIONS WOULD RESULT
FROM ANY PROPOSED TRANSFER OR ASSIGNMENT.

                          COMMON STOCK PURCHASE WARRANT

                                   AXONYX INC.

         THIS CERTIFIES that for good and valuable consideration received,
_________________________ or a registered assignee (the "Holder") is entitled,
upon the terms and subject to the conditions hereinafter set forth, to acquire
from Axonyx Inc., a Nevada corporation (the "Corporation") up to
____________________ fully paid and nonassessable shares of common stock, par
value $0.001, of the Corporation ("Warrant Stock") at a purchase price per share
(the "Exercise Price") of $11.00 (the "Warrant").

1.       TERM OF WARRANT.

         Subject to the terms and conditions set forth herein, this Warrant
shall be exercisable, in whole or in part, at any time on or after the date
hereof and at or prior to 11:59 p.m., Eastern Standard Time, on August 1, 2004
(the "Expiration Time"). Notwithstanding the foregoing, the Corporation shall
have the right, except as may be limited by law, other agreements or herein, to
call this Warrant for exercise, in whole or in part, by mailing written notice
by United States mail to the registered Holder hereof if the average closing bid
price for the Corporation's common stock, as quoted by the Nasdaq Market or any
other established over-the-counter quotation service, is equal to or greater
than $20.00 per share, as adjusted pursuant to Section 11 hereof, for any
consecutive period of thirty days. In such event, this Warrant shall expire and
cease to be exercisable at 11:59 p.m. Pacific Standard Time, of the twenty-first
day after the date of mailing of the notice. Notwithstanding the foregoing, the
Corporation may not call this Warrant unless there is a current registration
statement covering the Warrant or the Warrant Stock.

2.       EXERCISE OF WARRANT.

         The purchase rights represented by this Warrant are exercisable by the
registered Holder hereof, in whole or in part, at any time and from time to time
at or prior to the Expiration Time by the surrender of this Warrant and the
Notice of Exercise form attached hereto duly executed to the office of the
Corporation at 750 Lexington Avenue, Suite 1400, New York, New York 10022 (or
such other office or agency of the Corporation as it may designate by notice in
writing to the registered Holder hereof at the address of such Holder appearing
on the books of the Corporation), and upon payment of the Exercise Price for the
shares thereby purchased (by cash or by check or bank draft payable to the order
of the Corporation or by cancellation of indebtedness of the Corporation to the
Holder hereof, if any, at the time of exercise in an amount equal to the
purchase price of the shares thereby purchased); whereupon the Holder of this
Warrant shall be entitled to receive from the Corporation a stock certificate in
proper form representing the number of shares of Warrant Stock so purchased.

3.       ISSUANCE OF SHARES; NO FRACTIONAL SHARES OF SCRIP.

         Certificates for shares purchased hereunder shall be delivered to the
Holder hereof by the Corporation's transfer agent at the Corporation's expense
within a reasonable time after the date on which this Warrant shall have been
exercised in accordance with the terms hereof. Each certificate so delivered
shall be in such denominations as may be requested by the Holder hereof and
shall be registered in the name of such Holder or, subject to applicable laws,
such other name as shall be requested by the Holder. If, upon exercise of this
Warrant, fewer than all of the shares of Warrant Stock evidenced by this Warrant
are purchased prior to the Expiration Time, one or more new warrants
substantially in the form of, and on the terms in, this Warrant will be issued
for the remaining number of shares of Warrant Stock not purchased upon exercise
of this Warrant. The Corporation hereby represents and warrants that all shares
of Warrant Stock which may be issued upon the exercise of this Warrant will,
upon such exercise, be duly and validly authorized and issued, fully paid and
nonassessable and free from all taxes, liens and charges in respect of the
issuance thereof (other than liens or charges created by or imposed upon the
Holder of the Warrant Stock). The Corporation agrees that the shares so issued
shall be and will be deemed to be issued to such Holder as the record owner of
such shares as of the close of business on the date on which this Warrant shall
have been surrendered for exercise in accordance with the terms hereof. No
fractional shares or scrip representing fractional shares shall be issued upon
the exercise of this Warrant. With respect to any fraction of a share called for
upon the exercise of this Warrant, an amount equal to such fraction multiplied
by the then current price at which each share may be purchased hereunder shall
be paid in cash to the Holder of this Warrant.

4.       LOCK UP, REGISTRATION RIGHTS.

         Pursuant to the terms of the Registration Rights Agreement signed in
conjunction with this Warrant, certain piggy-back registration rights apply to
the Warrant Stock with regard to any registration statement filed by the
Corporation. The Corporation may, at the request of an underwriter, if any,
limit or exclude such Warrant Stock from a registration statement in connection
with a public offering, or impose on each Holder a so-called "lock up" period in
connection with a public offering, which lock-up period will not exceed 12
months from the effective date of the registration statement for such public
offering. In addition, the Company may exclude the Warrant Stock from
registration statements filed pursuant to an acquisition, merger or under Form
S-8, and, if such registration statement includes registrable securities of
certain selling stockholders who purchased such registrable securities in a
previous private placement, the Company may exclude the Warrant Stock from such
registration statement. See the Registration Rights Agreement for a full
description of the piggy-back registration rights applicable to the Warrant
Stock and the limitations on such rights.

5.       CHARGES, TAXES AND EXPENSES.

         Issuance of certificates for shares of Warrant Stock upon the exercise
of this Warrant shall be made without charge to the Holder hereof for any issue
or transfer tax or other incidental expense in respect of the issuance of such
certificate, all of which taxes and expenses shall be paid by the Corporation,
and such certificates shall be issued in the name of the Holder of this Warrant
or in such name or names as may be directed by the Holder of this Warrant;
provided, however, that in the event certificates for shares of Warrant Stock
are to be issued in a name other than the name of the Holder of this Warrant,
this Warrant when surrendered for exercise shall be accompanied by an Assignment
Form to be provided by the Company duly executed by the Holder hereof.

6.       NO RIGHTS AS SHAREHOLDERS.

         This Warrant does not entitle the Holder hereof to any voting rights or
other rights as a shareholder of the Corporation prior to the exercise hereof.

7.       EXCHANGE AND REGISTRY OF WARRANT.

         This Warrant is exchangeable, upon the surrender hereof by the
registered Holder at the above mentioned office or agency of the Corporation,
for a new Warrant of like tenor and dated as of such exchange. The Corporation
shall maintain at the above-mentioned office or agency a registry showing the
name and address of the registered Holder of this Warrant. This Warrant may be
surrendered for exchange, transfer or exercise, in accordance with its terms, at
such office or agency of the Corporation, and the Corporation shall be entitled
to rely in all respects, prior to written notice to the contrary, upon such
registry.

                                       3

8.       LOSS, THEFT, DESTRUCTION OR MUTILATION OF WARRANT.

         Upon receipt by the Corporation of evidence reasonably satisfactory to
it of the loss, theft, destruction or mutilation of this Warrant and in case of
loss, theft or destruction of indemnity or security reasonably satisfactory to
it, and upon reimbursement to the Corporation of all reasonable expenses
incidental thereto, and upon surrender and cancellation of this Warrant, if
mutilated, the Corporation will make and deliver a new Warrant of like tenor and
dated as of such cancellation, in lieu of this Warrant.

9.       SATURDAYS, SUNDAYS AND HOLIDAYS.

         If the last or appointed day for the taking of any action or the
expiration of any right required or granted herein shall be a Saturday or a
Sunday or that is a legal holiday, then such action may be taken or such right
may be exercised on the next succeeding day not a Saturday, Sunday or legal
holiday.

10.      MERGER, SALE OF ASSETS, ETC.

         If at any time the Corporation proposes to merge or consolidate with or
into any other corporation, effect any reorganization, or sell or convey all or
substantially all of its assets to any other entity, then, as a condition of
such reorganization, consolidation, merger, sale or conveyance, the Corporation
or its successor, as the case may be, shall enter into a supplemental agreement
to make lawful and adequate provision whereby the Holder shall have the right to
receive, upon exercise of the Warrant, the kind and amount of equity securities
which would have been received upon such reorganization, consolidation, merger,
sale or conveyance by a Holder of a number of shares of common stock equal to
the number of shares issuable upon exercise of the Warrant immediately prior to
such reorganization, consolidation, merger, sale or conveyance. If the property
to be received upon such reorganization, consolidation, merger, sale or
conveyance is not equity securities, the Corporation shall give the Holder of
this Warrant ten (10) business days prior written notice of the proposed
effective date of such transaction, and if this Warrant has not been exercised
by or on the effective date of such transaction, it shall terminate.

11.      SUBDIVISION, COMBINATION, RECLASSIFICATION, CONVERSION, ETC.

         If the Corporation at any time shall by subdivision, combination,
reclassification of securities or otherwise, change the Warrant Stock into the
same or a different number of securities of any class or classes, this Warrant
shall thereafter entitle the Holder to acquire such number and kind of
securities as would have been issuable in respect of the Warrant Stock (or other
securities which were subject to the purchase rights under this Warrant
immediately prior to such subdivision, combination, reclassification or other
change) as the result of such change if this Warrant had been exercised in full
for cash

                                       4
<PAGE>

immediately prior to such change. The Exercise Price hereunder shall be adjusted
if and to the extent necessary to reflect such change. If the Warrant Stock or
other securities issuable upon exercise hereof are subdivided or combined into a
greater or smaller number of shares of such security, the number of shares
issuable hereunder shall be proportionately increased or decreased, as the case
may be, and the Exercise Price shall be proportionately reduced or increased, as
the case may be, in both cases according to the ratio which the total number of
shares of such security to be outstanding immediately after such event bears to
the total number of shares of such security outstanding immediately prior to
such event. The Corporation shall give the Holder prompt written notice of any
change in the type of securities issuable hereunder, any adjustment of the
Exercise Price for the securities issuable hereunder, and any increase or
decrease in the number of shares issuable hereunder.

12.      TRANSFERABILITY; COMPLIANCE WITH SECURITIES LAWS.

         (a) This Warrant may not be transferred or assigned in whole or in part
without compliance with all applicable federal and state securities laws by the
transferor and transferee (including the delivery of investment representation
letters and legal opinions reasonably satisfactory to the Corporation, if
requested by the Corporation). Subject to such restrictions, prior to the
Expiration Time, this Warrant and all rights hereunder are transferable by the
Holder hereof, in whole or in part, at the office or agency of the Corporation
referred to in Section 2 hereof. Any such transfer shall be made in person or by
the Holder's duly authorized attorney, upon surrender of this Warrant together
with the Assignment Form attached hereto properly endorsed.

         (b) The Holder of this Warrant, by acceptance hereof, acknowledges that
this Warrant and the Warrant Stock issuable upon exercise hereof are being
acquired solely for the Holder's own account and not as a nominee for any other
party, and for investment, and that the Holder will not offer, sell or otherwise
dispose of this Warrant or any shares of Warrant Stock to be issued upon
exercise hereof except under circumstances that will not result in a violation
of the Securities Act of 1933, as amended, or any state securities laws. Upon
exercise of this Warrant, the Holder shall, if requested by the Corporation,
confirm in writing, in a form satisfactory to the Corporation, that the shares
of Warrant Stock so purchased are being acquired solely for Holder's own account
and not as a nominee for any other party, for investment, and not with a view
toward distribution or resale.

         (c) The Warrant Stock has not been and will not be registered under the
Securities Act of 1933, as amended, and this Warrant may not be exercised except
by (i) the original purchaser of this Warrant from the Corporation or (ii) an
"accredited investor" as defined in Rule 501(a) under the Securities Act of
1933, as amended. Each certificate representing the Warrant Stock or other
securities issued in respect of the Warrant Stock upon any stock split, stock
dividend, recapitalization, merger, consolidation or similar event, shall be
stamped or otherwise imprinted with a legend

                                       5
<PAGE>

substantially in the following form (in addition to any legend required under
applicable securities laws):

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND
NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF, AND
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH
SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR
UNLESS THE SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS
DELIVERY REQUIREMENTS OF SAID ACT.

13.      REPRESENTATIONS AND WARRANTIES.

         The Corporation hereby represents and warrants to the Holder hereof
that:

         (a) during the period this Warrant is outstanding, the Corporation will
reserve from its authorized and unissued common stock a sufficient number of

Corporation's officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the shares of

         (c) the Corporation has all requisite legal and corporate power to
execute and deliver this Warrant, to sell and issue the Warrant Stock hereunder,
and to carry out and perform its obligations under the terms of this Warrant;

         (d) all corporate action on the part of the Corporation, its directors
and stockholders necessary for the authorization, execution, delivery and
performance of this Warrant by the Corporation, the authorization, sale,
issuance and delivery of the Warrant Stock, the grant of registration rights as
provided herein and the performance of the Corporation's obligations hereunder
has been taken;

         (e) the Warrant Stock, when issued in compliance with the provisions of
this Warrant and the Corporation's Articles of Incorporation (as they may be
amended from time to time), will be validly issued, fully paid and
nonassessable, and free of all taxes, liens or encumbrances with respect to the
issue thereof, and will be issued in compliance with all applicable federal and
state securities laws; and

         (d) the issuance of the Warrant Stock will not be subject to any
preemptive rights, rights of first refusal or similar rights.

14.      CORPORATION GOOD FAITH.

         The Corporation will not, by amendment of its Articles of Incorporation
or through any reorganization, recapitalization, transfer of assets,

action, avoid or seek to avoid the observance or performance of any of the terms
to be observed or performed hereunder by the Corporation, but will at all times
in good faith assist in the carrying out of all the provisions of this Warrant
and in the taking of all such action as may be necessary or appropriate in order
to protect the rights of the Holder of the Warrant against impairment.

                                                                     Exhibit 4.2
                          REGISTRATION RIGHTS AGREEMENT

         THIS AGREEMENT, dated as of the ___ day of           , 1999, between
the person whose name and address appears on the signature page
(individually, a "Holder" or, collectively with the holders of the securities
issued in the Offering, each as defined below, the "Holders"), and AXONYX
INC., with its principal executive offices at 750 Lexington Avenue, Suite
1400, New York, New York 10022 (the "Company").

         WHEREAS, simultaneously with the execution and delivery of this
Agreement, the Holder is purchasing from the Company (the "Offering") ________
units (the "Units"), each Unit consisting of 4,000 shares (the "Shares") of
Common Stock, $0.001 par value (the "Common Stock") of the Company and 2,000
Warrants to purchase shares of Common Stock (the "Warrant Shares").

         WHEREAS, the Company desires to grant to the Holder the registration
rights set forth herein with respect to the Warrant Shares issuable upon
exercise of the Warrants;

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

         1. REGISTRABLE SECURITIES. As used herein the term "Registrable
Security" means each of the Warrant Shares; provided, however, that with respect
to any particular Registrable Security, such security shall cease to be a
Registrable Security when, as of the date of determination, (i) it has been
effectively registered under the Securities Act of 1933, as amended (the
"Securities Act") and disposed of pursuant thereto, or (ii) registration under
the Securities Act is no longer required for the immediate public distribution
of such Registrable Security. In the event of any merger, reorganization,
consolidation, recapitalization or other change in corporate structure affecting
the Common Stock, such adjustment shall 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 Section 1. For purposes
hereof, Registrable Securities does not include the Shares.

         2. PIGGYBACK REGISTRATION. If, during the term of the Warrants, the
Company proposes to prepare and file with the Securities and Exchange Commission
(the "Commission") a registration statement covering equity or debt securities
of the Company, or any such securities of the Company held by its shareholders
or the security holders of the Company (in any such case, other than in
connection with a merger, acquisition or pursuant to Form S-8 or successor form)
(for purposes of this Section 2, collectively, a "Registration Statement"), it
will give written notice of its intention to do so by registered mail
("Notice"), at least thirty (30) days prior to the filing of each such
Registration Statement, to all Holders of the Registrable Securities. Upon the
written request of such a Holder (a "Requesting Holder"), made within twenty
(20) days after receipt of the Notice, that the Company include any of the
Requesting Holder's

                                                                               1

<PAGE>

Registrable Securities in the proposed Registration Statement, the Company
shall, as to each such Requesting Holder, use its best efforts to effect the
registration under the Securities Act of the Registrable Securities which it has
been so requested to register ("Piggyback Registration"), at the Company's sole
cost and expense and at no cost or expense to the Requesting Holders except as
provided in Section 4(b) hereof.

         3. DEFERRAL OR LIMITATION OF REGISTRATION, LOCK UP. Notwithstanding the
provisions of Section 2 above, (i) the Company shall have the right at any time
after it shall have given written notice pursuant to Section 2 (irrespective of
whether any written request for inclusion of such securities shall have already
been made) to elect not to file any such proposed Registration Statement, or to
withdraw the same after the filing but prior to the effective date thereof; or
(ii) if an underwriter of an offering for which a Registration Statement is
filed so requests in writing, the Registrable Securities shall not be offered or
sold until the expiration of a date not to exceed 12 months from the effective
date of the Registration Statement that gave rise to the Piggyback Registration
("Lock Up"); (iii) if such underwriter of an offering for which a Registration
Statement is filed so requests in writing, the Company may exclude the
Registrable Securities from such registration statement; or (iv) in the event of
a Registration Statement filed by the Company with respect to an offering for
its own account, which Registration Statement includes the resale of securities
of selling stockholders who hold securities registrable pursuant to a
registration rights agreement with the Company and who acquired such registrable
securities in a private placement prior to the Holders, the Company may limit,
defer or exclude the Registrable Securities from such registration statement.

         4. COVENANTS OF THE COMPANY WITH RESPECT TO REGISTRATION.

         The Company covenants and agrees as follows:

                  (a) In connection with any registration filed pursuant hereto,
the Company shall use its best efforts to cause the Registration Statement to
become effective as promptly as possible and, if any stop order shall be issued
by the Commission in connection therewith, to use its reasonable efforts to
obtain the removal of such order. Following the effective date of a Registration
Statement, the Company shall, upon the request of the Holder, forthwith supply
such reasonable number of copies of the Registration Statement, preliminary
prospectus and prospectus meeting the requirements of the Securities Act, and
other documents necessary or incidental to the public offering of the
Registrable Securities, as shall be reasonably requested by the Holder to permit
the Holder to make a public distribution of the Holder's Registrable Securities.
The obligations of the Company hereunder with respect to the Holder's
Registrable Securities are subject to the Holder's furnishing to the Company
such appropriate information concerning the Holder, the Holder's Registrable
Securities and the terms of the Holder's offering of such Registrable Securities
as the Company may reasonably request in writing.

                                                                               2
<PAGE>

                  (b) The Company shall pay all costs, fees and expenses in
connection with all Registration Statements filed pursuant to Section 2 hereof
including, without limitation, the Company's legal and accounting fees, printing
expenses, and blue sky fees and expenses; provided, however, that the Holder
shall be solely responsible for the fees of any counsel retained by the Holder
in connection with such registration and any transfer taxes or underwriting
discounts, commissions or fees applicable to the Registrable Securities sold by
the Holder pursuant thereto.

         (c) The Company will take all necessary action which may be required in
qualifying or registering the Registrable Securities included in a Registration
Statement for offering and sale under the securities or blue sky laws of such
states as are reasonably requested by the Holders of such securities, provided
that the Company shall not be obligated to execute or file any general consent
to service of process or to qualify as a foreign corporation to do business
under the laws of any such jurisdiction.

         (d) The Company will take all necessary action required to keep any
Registration Statement filed pursuant to Section 2 hereof current during the
term of the Warrants.

         5.       ADDITIONAL TERMS.

                  (a) The Company shall indemnify and hold harmless the Holder
and each underwriter, within the meaning of the Securities Act, who may purchase
from or sell for the Holder, any Registrable Securities, from and against any
and all losses, claims, damages and liabilities caused by any untrue statement
of a material fact contained in the Registration Statement, any other
registration statement filed by the Company under the Securities Act with
respect to the registration of the Registrable Securities, any post-effective
amendment to such registration statements, or any prospectus included therein or
caused by any omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, except
insofar as such losses, claims, damages or liabilities are caused by any such
untrue statement or omission based upon information furnished or required to be
furnished in writing to the Company by the Holder expressly for use therein,
which indemnification shall include each person, if any, who controls either the
Holder within the meaning of the Securities Act and each officer, director,
employee and agent of the Holder; provided, however, that the indemnification in
this Section 5(a) with respect to any prospectus shall not inure to the benefit
of the Holder (or to the benefit of any person controlling the Holder) on
account of any such loss, claim, damage or liability arising from the sale of
Registrable Securities by the Holder, if a copy of a subsequent prospectus
correcting the untrue statement or omission in such earlier prospectus was
provided to the Holder by the Company prior to the subject sale and the
subsequent prospectus was not delivered or sent by the Holder to the purchaser
prior to such sale and provided further, that the Company shall not be obligated
to so indemnify the Holder or other person referred to above unless the Holder
or other person, as the case may be, shall at the same time indemnify the
Company, its directors, each officer signing the Registration Statement and

                                                                               3
<PAGE>

each person, if any, who controls the Company within the meaning of the
Securities Act, from and against any and all losses, claims, damages and
liabilities caused by any untrue statement of a material fact contained in the
Registration Statement, or any prospectus required to be filed or furnished by
reason of this Agreement or caused by any omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, insofar as such losses, claims, damages or liabilities are
caused by any untrue statement or omission based upon information furnished in
writing to the Company by the Holder or underwriter expressly for use therein.

                  (b) If for any reason the indemnification provided for in the
preceding section is held by a court of competent jurisdiction to be unavailable
to an indemnified party with respect to any loss, claim, damage, liability or
expense referred to therein, then the indemnifying party, in lieu of
indemnifying such indemnified party thereunder, shall contribute to the amount
paid or payable by the indemnified party as a result of such loss, claim, damage
or liability in such proportion as is appropriate to reflect not only the
relative benefits received by the indemnified party and the indemnifying party,
but also the relative fault of the indemnified party and the indemnifying party,
as well as any other relevant equitable considerations.

                  (c) Neither the filing of a Registration Statement by the
Company pursuant to this Agreement nor the making of any request for
prospectuses by the Holder shall impose upon the Holder any obligation to sell
the Holder's Registrable Securities.

                  (d) The Holder, upon receipt of notice from the Company that
an event has occurred which requires a post-effective amendment to the
Registration Statement or a supplement to the prospectus included therein, shall
promptly discontinue the sale of Registrable Securities until the Holder
receives a copy of a supplemented or amended prospectus from the Company, which
the Company shall provide as soon as practicable after such notice.

                  (e) If the Company fails to keep the Registration Statement
referred to above continuously effective during the requisite period, then the
Company shall, promptly upon the request of the Holders of at least a majority
of the unsold Registrable Securities, use its best efforts to update the
Registration Statement or file a new registration statement covering the
Registrable Securities remaining unsold, subject to the terms and provisions
hereof.

                  (f) The Holder agrees to provide the Company with any
information or undertakings reasonably requested by the Company in order for the
Company to include any appropriate information concerning the Holder in the
Registration Statement or in order to promote compliance by the Company or the
Holders with the Securities Act.

         6. GOVERNING LAW. The Registrable Securities will be, if and when
