RIGHTS AGREEMENT AMENDMENT

This Amendment, dated as of June 7, 2006, to the Rights Agreement, dated as of May 13, 2005 (the
“Rights Agreement”), is between Axonyx Inc., a Nevada corporation (the “Company
”), and The Nevada Agency and Trust Company (the “Rights Agent”).

The Company and the Rights Agent have heretofore executed and entered into the Rights Agreement.
Pursuant to Section 27 of the Rights Agreement, the Company and the Rights Agent may from time to time supplement or amend the Rights Agreement in accordance with the provisions of
Section 27 thereof and the Company desires and directs the Rights Agent to so amend the Rights Agreement.  All acts and things necessary to make this Amendment a valid agreement according to its
terms have been done and performed, and the execution and delivery of this Amendment by the Company and the Rights Agent have been in all respects authorized by the Company and the Rights Agent.

In consideration of the foregoing premises and mutual agreements set forth in the Rights Agreement and
this Amendment, the parties hereto agree as follows:

1.            
Section 1(a) of the Rights Agreement, which sets forth the definition of “Acquiring Person,” is hereby modified and amended to read in its entirety as follows:

(a)          
“Acquiring Person” shall mean any Person (as such term is hereinafter defined) who or which, together with all Affiliates (as such term is hereinafter defined) and Associates (as such term
is hereinafter defined) of such Person, shall be the Beneficial Owner (as such term is hereinafter defined) of 15% or more of the shares of Common Stock then outstanding or who was such a Beneficial
Owner at any time after the date hereof, whether of not such Person continues to be the Beneficial Owner of 15% or more of the outstanding shares of Common Stock.  Notwithstanding the foregoing, (i)
in no event shall a Person who or which, together with all Affiliates and Associates of such Person, is the Beneficial Owner of less than 15% of the Company’s outstanding shares of Common Stock

become an Acquiring Person solely as a result of a reduction of the number of shares of outstanding Common Stock, including repurchases of outstanding shares of Common Stock by the Company, which
reduction increases the percentage of outstanding shares of Common Stock beneficially owned by such Person (provided that any subsequent increase in the amount of Common Stock beneficially owned by
such Person, together with all Affiliates and Associates of such Person, without the prior approval of the Company shall cause such Person to be an Acquiring Person); (ii) the term Acquiring Person
shall not mean (A) the Company, (B) any subsidiary of the Company (as such term is hereinafter defined), (C) any employee benefit plan of the Company or any of its subsidiaries, or (D) any entity
holding securities of the Company organized, appointed or established by the Company or any of its subsidiaries for or pursuant to the terms of any such plan; and (iii) no Person shall be deemed to
be an

Acquiring Person if (A) within five business days after such Person would otherwise have become an Acquiring Person (but for the operation of this clause (iii)), such Person notifies the Board of
Directors that such Person did so inadvertently and, within two business days after such notification, such Person is the Beneficial Owner of less than 15% of the outstanding shares of Common Stock,
(B) by reason of such 

 

Person’s Beneficial Ownership of 15% or more of the outstanding shares of Common Stock on the date hereof if,
prior to the Record Date, such Person notifies the Board of Directors that such Person is no longer the Beneficial Owner of 15% or more of the then outstanding shares of Common Stock or (C) the Board
of Directors determines in good faith that a Person who would otherwise be an Acquiring Person, as defined pursuant to the foregoing provisions of this paragraph (a), has become such inadvertently,
and such Person divests Beneficial Ownership as promptly as practicable of a sufficient number of shares of Common Stock so that such Person would no longer be an Acquiring Person, as defined
pursuant to the foregoing provisions of this paragraph (a).  In addition, notwithstanding the foregoing, none of TorreyPines Therapeutics, Inc., a Delaware corporation (“TorreyPines”), or
any Affiliate or

Associate thereof, or any stockholder of TorreyPines shall become an “Acquiring Person” as a result of (i) the approval, execution, delivery or performance of that certain Agreement and

to have occurred in connection with or as a result of (i) the approval, execution, delivery or performance of the Merger Agreement, (ii) the consummation of the Merger, (iii) the issuance of Common
Stock and Merger Warrants pursuant to the Merger Agreement or the issuance of Warrant Shares, (iv) the announcement of the Merger Agreement or the Merger or (v) the consummation of any other
transaction contemplated by the Merger Agreement, including the approval, execution and delivery of the TorreyPines Stockholder Voting Agreements.

3.            
Section 3(b) of the Rights Agreement is hereby amended by adding as the final sentence thereto the following:

clauses (x) through (z) of the first sentence of Section 13(a) shall be deemed to have occurred solely as a result of (i) the approval, execution, delivery or performance of the Merger
Agreement, (ii) the consummation of the Merger, (iii) the issuance of Common Stock and Merger Warrants pursuant to the Merger Agreement or the issuance of Warrant Shares, (iv) the announcement of the
Merger Agreement or the Merger or (v) the consummation of any other transaction contemplated by the Merger Agreement, including the approval, execution and delivery  of the TorreyPines Stockholder
