Dear Albert:

         1. In consideration of the introduction by Flow Capital Advisors, Inc.,
a Delaware corporation (the "Finder"), of Great Eastern Securities. Inc., a New
York corporation (the "Target"), to JAG Media Holdings, Inc., a Nevada
corporation (the "Company"), the Company hereby agrees to pay the Finder, if an
Acquisition is consummated with such Target on or before December 31, 2005, a
fee, payable upon the unconditional closing of the Acquisition, equal to five
percent (5.0%) of the aggregate Consideration paid by the Company for the
Acquisition of such Target. As used herein, (a) the term "Acquisition" shall
mean the direct or indirect acquisition of all or a substantial portion of the
stock or assets of the Target by the Company, including by means of merger, and
(b) the term "Consideration" shall mean the number of shares of Class A Common
Stock, par value $0.00001 per share (or any security into which such Class A
Common Stock shall hereafter be reclassified), issued or issuable by the Company
to the Target (or the owners thereof) as payment for the Target.

         2. The Finder's fee as described in Section 1 above shall be payable in
the shares of stock in which the Company makes payment of the Consideration and
shall be deemed earned and payable upon payment by the Company of the
Consideration at the unconditional closing of the Acquisition of the Target by
the Company. If any part of the Consideration shall be payable in installments,
escrowed or shall be contingent upon any event or circumstance, the Finder's fee
shall be deemed earned and payable in the same proportionate amounts and at the
same times as such installments, escrowed or contingent payments are made. The
Finder shall be responsible for the payment of all federal, state, foreign and
local taxes, tariffs, or surcharges that may be due and payable to government
authorities on such fees the Finder is entitled to receive pursuant to the terms
of this letter agreement (this "Letter Agreement"), and the Company shall be
authorized to make any withholdings in respect of such taxes as may be required
under applicable law. The Finder will not be entitled to any compensation if for
any reason whatsoever the Acquisition of the Target is not completed before
December 31, 2005, whether or not there is a binding agreement to do so and
whether or not a default by the Company or any of its affiliates has caused the
failure to complete the Acquisition.

                                       1
<PAGE>

         3. The Finder shall not be reimbursed by the Company for any expenses
incurred by him in connection with this Letter Agreement or otherwise.

         4. The Finder shall not receive any additional compensation directly or
indirectly from the Target, or any party affiliated with the Target, for acting
as a finder in connection with the Acquisition. Nothwithstanding the foregoing,
nothing herein shall prohibit Finder from rendering investment banking
consulting services to the Target prior to or after the Acquisition.

         5. The Finder shall indemnify and hold harmless the Company and any of
its affiliates against any losses, claims, damages or liabilities for brokerage
or finder's fees or other compensation claimed by any person, firm or entity
whose services the Finder has engaged or may engage in connection with the
proposed Acquisition of the Target by the Company.

         6. It is understood and agreed that the Finder is an independent
contractor and shall not be deemed the Company's agent for any purpose
whatsoever, and the Finder is not granted any right or authority to assume or
create any obligation or liability of any kind or nature, express or implied, on
behalf of the Company, to make any representation on behalf of the Company or to
bind the Company in any manner or thing whatsoever.

         7. Neither the Finder nor any of his affiliates or associates, in any
capacity, shall issue any press release or public announcement relating to the
matters set forth herein or any Acquisition without the prior express written
consent of the Company.

         8. The Finder covenants and agrees with the Company that, except with
the prior written consent of the Company, the Finder and its representatives (a)
will hold in strict confidence any data or information obtained from the
Company, the Target, any person associated with the Company or the Target or
from any representative of the Company or the Target, including, without
limitation, information pertaining to the financial condition, results of
operations, methods of operations and products of the Company or the Target or
pertaining to the availability of and negotiations regarding the Target;
provided, however, that this duty of confidentiality shall not apply to any data
or information which prior to any disclosure by the Finder or its
representatives is in the public domain other than as a result of disclosure by
the Finder or its representatives, and (b) will not disclose any data or
information to be held in confidence pursuant to this paragraph 8 to any other
party except to the extent that disclosure may be required by law; provided,
however, that the Finder shall provide the Company with written notice of such
requirement as soon as practicable after learning of it such that the Company
may seek a protective order or other appropriate remedy and, if no such order or
remedy is obtained, the Finder and his representatives shall furnish only that
portion of such confidential data and information which the Finder is advised by
written opinion of counsel is legally required and only in the manner legally
required. All such data and information to be held in confidence pursuant to
this paragraph 8 shall be used by the Finder and its representatives only for
the purposes of fulfilling the Finder's role in assisting in the Acquisition of
the Target as contemplated herein. At any time upon the Company's request, the
Finder shall return to the Company all data, information and other written
material respecting the Company or the Target obtained by the Finder in
connection with the matters contemplated by this Letter Agreement. The Finder
further agrees that its representatives who are given access to the data and
information to be kept confidential pursuant to this paragraph 8 shall be bound
by the terms of this paragraph 8 and the Finder will insure that such
representatives adhere to the terms contained herein.

Company, whether voluntarily or by operation of law. This Letter Agreement shall
inure to the benefit of, and be binding upon, the parties hereto and their
respective successors and assigns.

         11. This Letter Agreement constitutes the entire agreement between the

further force and effect upon the earliest to occur of (a) the unconditional
closing of the Acquisition of the Target by the Company and payment by the
Company of the Finder's fee described in Section 1 hereof, (b) the mutual
written agreement of the Company on the one hand and the Finder on the other
hand and (c) December 31, 2005. Notwithstanding the foregoing, the provisions
contained in paragraphs 5, 7 and 8 hereof shall survive the termination of this

governed by the laws of the State of New York applicable to contracts made and
to be fully performed in such State.

                        Form of Share Exchange Agreement

Axonyx Inc.
500 Seventh Avenue, 10th Floor
New York, NY 10018
Attention: Marvin Hausman, M.D., CEO

      Re:   Share Exchange

Dear Dr. Hausman:

      The undersigned (the "Seller") is the holder of that number of shares of
the common stock, par value $0.001 per share, of Oxis International, Inc., a
Delaware corporation ("Oxis"), set forth on the signature page of this letter
(the "Shares"). This letter sets forth the terms of our agreement to exchange
the Shares for shares of common stock of Axonyx Inc. ("Axonyx") in accordance
with the terms below.

      1. Share Exchange. Subject to the terms and subject to conditions of this
letter agreement, the undersigned hereby agrees to exchange all of the Shares
for shares of common stock of Axonyx ("Axonyx Common Stock"), at an exchange
ratio of 0.1157187 (the "Exchange Ratio"); that is, each share of Oxis common
stock will be exchanged for 0.1157187 share of Axonyx Common Stock. The Exchange
Ratio is based upon the average reported closing prices for the common stock of
Oxis and Axonyx for the ten-day trading period commencing December 26, 2003 and
ending January 9, 2003. Fractional shares of Axonyx Common Stock will not be
issued; any fractional share of Axonyx Common Stock issuable upon the exchange
for shares of Oxis Common Stock will be rounded up to the next nearest whole
share of Axonyx Common Stock.

      For example, if the undersigned holds 100,000 shares of Oxis Common Stock,
the number of Exchange Shares to be issued would be 11,571.87 shares of Axonyx
Common Stock, which after rounding up for the fractional share interest, would
equal 11,572 shares.

      2. Deliveries. The Seller has executed this letter agreement and has
delivered a copy by fax to Axonyx's counsel, Ehrenreich Eilenberg & Krause LLP
(Fax no. 212-986-2399, Attention: Adam Eilenberg, Esq.). Immediately, and not
more than two (2) business days following our receipt of a signed signature page
of this letter agreement from Axonyx, the undersigned shall deliver to such
counsel by Federal Express or other overnight courier at 11 East 44th Street,
17th Floor, New York, NY 10017, an original executed copy of the signature page
of this letter agreement, together with (a) an originally executed stock power,
with signature guarantee, in the form attached hereto as Exhibit A (the "Stock
Power"), relating to the Shares and (b) either the original share certificate
evidencing the Shares or an originally executed lost stock certificate affidavit
in the form attached hereto as Exhibit B. The signature guaranty shall be
executed by a bank or other financial institution, including a brokerage firm.
As soon as practicable, and in any event not more than ten (10) business days
following delivery by Axonyx of a signed signature page to this letter agreement
to the undersigned, Axonyx shall cause to be delivered a share certificate
reflecting the Exchange Shares. If the undersigned does not receive a signed
copy of this letter agreement within ten (10) business days of delivering to
Axonyx a signed copy of this letter, the obligations of the Seller hereunder
shall terminate.

      3. Registration Rights. The Seller acknowledges that the Exchange Shares
to be issued by

                                       1
<PAGE>

Axonyx will be "restricted securities" and will not be registered under the
federal securities laws, and therefore will bear a restrictive legend to that
effect. Within 10 days following the declaration of effectiveness of a
registration statement on Form S-3 relating to the resale of shares of Axonyx
Common Stock purchased by the investors in a $50 million dollar investment
round, as described in Axonyx's Form 8-K filed on January 12, 2004, Axonyx shall
file a registration statement on Form S-3 relating to the resale of the Exchange
Shares (the "Resale S-3") and shall use its best efforts thereafter to cause the
Resale S-3 to be declared effective by the Securities and Exchange Commission.
Axonyx shall bear the costs and expenses relating to the Resale S-3 customarily
borne by the issuer filing a resale registration statement for the holders of
its securities.

      4. Representations and Warranties of the Seller. The undersigned hereby
represents and warrants to Axonyx as follows:

            (a) Organization, Authority and Qualification. [If the Seller is an
entity:] The Seller is a corporation, limited liability company, limited
partnership, trust or other entity duly organized, validly existing and in good
standing under the laws of its incorporation or formation and has the requisite
power and authority to execute and deliver this letter agreement and any of the
Exhibits contemplated hereby, to carry out its obligations hereunder and to
consummate the transactions contemplated hereby. The execution and delivery of
this letter agreement by the Seller and the consummation of the transactions
contemplated hereby and thereby have been duly authorized by all necessary
corporate action on the part of the Seller.

            (b) Ownership of the Shares. The Seller is the beneficial and record
owner of and has good, valid and marketable title to all of the Shares, free and
clear of all liens, mortgages, charges or other encumbrances and any preemptive
or subscription rights.

            (c) No Consents. Except as may be required under the Securities Act
of 1933, and subject to Axonyx's counsel providing any opinions in connection
therewity, the Seller is not required to obtain any order, consent, approval or
authorization of any person or entity in connection with the exchange of the
Shares for the Exchange Shares.

            (d) Investment Intent. The Exchange Shares which are being acquired
by the Seller in exchange for the Shares are being acquired for the Seller's own
account, not as nominee or agent, and not with a view towards the resale or
distribution of all or any part of the Exchange Shares. The Seller has no
intention of selling, transferring or distributing as a dividend or otherwise
any part of the Exchange Shares and has not entered into any agreement or
understanding with any party to do so.

            (e) Seller's Actions. The Seller has not acted and will not act in
concert with any other stockholder of Oxis, either in the negotiation and
execution of this letter agreement or in connection with the consummation of the
transactions contemplated hereunder. The Seller is not a member of any "group",
as defined under the federal securities laws, with respect to the Seller's
ownership or sale of the Shares, the voting thereof, or otherwise in connection
with Oxis, and the Seller has no agreement, written or oral, with any
stockholder of Oxis or any third party relating to any matter concerning the
affairs of Oxis. The Seller acknowledges that the Seller has separately
negotiated with Axonyx the terms and conditions of this letter agreement and
that the delivery of a signed copy hereof to Axonyx does not mean that Axonyx
has made any offer to the Seller to acquire the Shares or that the Seller is
making an offer to Axonyx to sell the Shares to it. The Seller is not acquiring
the Exchange Shares as a result of any general solicitation or general
advertisement by Axonyx, or any offer or other limited solicitation by Axonyx to
stockholders of Oxis.

            (f) Seller' Status. The Seller is an "accredited investor" as
defined in Rule 501(a)

                                       2
<PAGE>

under the Securities Act of 1933, as amended (the "Securities Act").

            (g) Experience of the Seller. The Seller, either alone or together
with its representatives, has such knowledge, sophistication and experience in
business and financial matters so as to be capable of evaluating the merits and
risks of the prospective investment in the Exchange Shares, and has so evaluated
the merits and risks of such investment. The Seller is able to bear the economic
risk of an investment in the Exchange Shares and, at the present time, is able
to afford a complete loss of such investment.

      5. Representations and Warranties of Axonyx. In order to induce the Seller
to enter into this letter agreement, Axonyx hereby represents and warrants to
the Seller as follows:

of the State of Nevada and has the requisite power and authority to execute and
deliver this letter agreement, to carry out its obligations hereunder and to

this letter agreement by Axonyx and the consummation by Axonyx of the
transactions contemplated hereby and thereby have been duly authorized by all
necessary corporate action on the part of Axonyx.

            (b) No Consents. Axonyx is not required to obtain any order,
consent, approval or authorization of any person or entity in connection with
the issuance of the Exchange Shares in exchange for the Shares or any of the
other transactions contemplated hereunder.

            (c) Issuance of the Exchange Shares. The Exchange Shares, when
issued, will be duly authorized by all necessary corporate action by Axonyx, and
will be duly and validly issued, fully paid and non-assessable shares of common
stock of Axonyx.

            (d) Investment Intent. The Shares which are being acquired by Axonyx
in exchange for the Exchange Shares are being acquired for Axonyx's own account,
not as nominee or agent, and not with a view towards the resale or distribution
of all or any part of the Shares. Axonyx has no intention of selling,
transferring or distributing as a dividend or otherwise any part of the Shares
and has not entered into any agreement or understanding with any party to do so.

            (e) SEC Reports. Axonyx has filed all reports required to be filed
by it under the Securities Act and the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), including pursuant to Section 13(a) or 15(d)
thereof, for the two years preceding the date hereof (or such shorter period as
the Company was required by law to file such material) (the foregoing materials,
including the exhibits thereto, being collectively referred to herein as the
"SEC Reports") on a timely basis or has received a valid extension of such time
of filing and has filed any such SEC Reports prior to the expiration of any such
extension. As of their respective dates, the SEC Reports complied in all
material respects with the requirements of the Securities Act and the Exchange
Act and the rules and regulations of the Securities and Exchange Commission
promulgated thereunder, and none of the SEC Reports, when filed, contained any
untrue statement of a material fact or omitted to state 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.

      6. Further Assurances. The Seller and Axonyx shall execute and deliver
such further instruments of conveyance, transfer and assignment, cooperate and
assist in providing information for making and completing regulatory filings,
and take such other actions as the Seller or Axonyx, as the case may be, may
reasonably require of the other party to evidence or effectuate the transactions
contemplated hereunder.

      7. Amendment. This Agreement may not be amended or otherwise modified,
except by an instrument in writing signed by, or on behalf of, each of the
parties hereto.

      8. Governing Law. This letter agreement (including the documents and
instruments referred to herein) shall be governed in all respects, including
validity, interpretation and effect, by the laws of the State of New York, as
applied to agreements entered into and wholly performed within such State.

      9. Counterparts. This letter agreement may be executed in one or more
counterparts which together shall constitute a single agreement. If any
provisions of this Agreement shall be held to be illegal, invalid or
unenforceable under any applicable law, then such contravention or invalidity
shall not invalidate the entire letter agreement. Such provision shall be deemed
to be modified to the extent necessary to render it legal, valid and
enforceable, and if no such modification shall render it legal, valid and
enforceable, then this letter agreement shall be construed as if not containing
the provision held to be invalid, and the rights and obligations of the parties
shall be construed and enforced accordingly.

      10. Entire Agreement. This letter agreement supersedes all prior
agreements between the parties hereto with respect to its subject matter and
constitutes a complete and exclusive statement of the terms of the agreement
between the parties with respect to its subject matter.
