     This AGREEMENT is made on March 13, 2006 by and among CENTRAL AMERICAN
EQUITIES CORP.,  a Florida corporation ("CAE"), and RICHARD WM. TALLEY, MICHAEL
CAGGIANO and P. JAMES VOLOSHIN (collectively, the "Shareholders").

                                  RECITALS

     On the date hereof, CAE has entered into an agreement with Ostar
Pharmaceutical, Inc., a Delaware corporation ("Ostar") providing for the merger
of  Ostar Acquisition Corp., a wholly owned subsidiary of CAE with and into
Ostar (the "Merger").  As a result of the Merger, the shareholders of Ostar will
acquire a majority of the shares of capital stock of CAE.

     The Shareholders, who are current holders of common stock of CAE, wish to
acquire from CAE the right to purchase all of the subsidiaries owned by CAE
("Subsidiaries," as further defined below) on the date hereof upon the terms and
conditions set forth herein within the "Option Period" (as defined below).  CAE
is willing to grant such right to the Shareholders, and, in addition, CAE wishes
to have the right to require the Shareholders to purchase the Subsidiaries
within the Option Period.

     NOW, THEREFORE, it is hereby agreed, by and among the parties hereto, as
follows:

     1.      Subsidiaries.  The "Subsidiaries" subject to this Agreement shall
include the following entities, all of which are organized under the laws of the
Republic of Costa Rica.  CAE warrants that it owns all of the issued and
outstanding capital stock of each of the Subsidiaries.

             Hotelera Cal Tico, S.A.
             Hotelero del Sol Marino FM, S.A.
             Sociedad Protectora De La Fuana y Flora Maritima De Mal Pais, S.A.
             Ecoprojecto San Luis, S.A.
             Confluencia San Luis, S.A.
             Corporacion Muxia, S.A.

     2.      Shareholders' Option.  CAE hereby grant to the Shareholders an
irrevocable option  (the "Shareholders' Option") to purchase all of the
shares owned by CAE  in each of the Subsidiaries ("Subsidiary Shares") at any
time during the period commencing ninety (90) days after the closing of the
Merger and ending one hundred and eighty (180) days from the date of such
closing ("Option Period").  The Shareholders may exercise the Shareholders'
Option at any time during the Option Period by giving notice of exercise, in
writing, to CAE.  The notice of exercise of the Shareholders' Option must be
duly executed by all of the Shareholders in order to be effective. Upon
receipt of such notice, CAE shall be bound to sell, and the Shareholders
shall be bound to purchase, all of the Subsidiary Shares for the purchase
price of $300,000 (the "Purchase Price") and upon the additional terms and
conditions set forth in this Agreement.

     3.      CAE's Option.  The Shareholders hereby grant to CAE an irrevocable
option to require the Shareholders to purchase the Subsidiary Shares (the
"CAE Option") at any time during the Option Period.  CAE may exercise the CAE
Option at any time during the Option Period by giving notice of exercise, in
writing, to the Shareholders.  Upon receipt of such notice, the Shareholders
shall be bound to purchase, and CAE shall be bound to sell, all of the
Subsidiary Shares for the Purchase Price and upon the additional terms and
conditions set forth in this Agreement.

     4.      Closing.  The closing of the sale pursuant to exercise of the
Shareholders' Option or the CAE Option (the "Closing") shall take place as
soon as reasonably possible.  Unless the Closing occurs at an earlier date or
other place by agreement of the parties, the Closing will take place at the
executive offices of CAE on the fourteenth day following the exercise of the
Option. At the Closing:

     (a)     CAE shall deliver

             (a) stock certificates representing its entire ownership interest
                 in each of the Subsidiaries, in each case duly endorsed for
                 transfer or accompanied by a duly executed stock power,
             (b) the books and records of the Subsidiaries; and
             (c) the resignations of the officers and directors of the
                 Subsidiaries.

      (b)    The Shareholders shall deliver
             (i) the Purchase Price in cash;
            (ii) an instrument satisfactory in form and substance to CAE and
                 its counsel providing for the assumption by the Shareholders,
                 jointly and severally, of all liabilities of CAE that existed
                 on the date of closing of the Merger or that arose thereafter
                 in connection with or arising out of the operation and owner-
                 ship of the Subsidiaries; and
           (iii) written releases of CAE from liability executed by each and
                 every creditor of CAE as of the closing of the Merger and any
                 creditor of CAE whose rights arose after the closing of the
                 Merger by reason of CAE's operation or ownership of the
                 Subsidiaries.

     5.      CAE's' Representations.  CAE represents and warrants to the
Shareholders that, as of the date hereof, and at all times until the Option
Period expires or the Closing takes place:

     (a)     CAE is and shall remain the sole legal and beneficial owner of the
             Subsidiary Shares; and CAE has not and shall not have sold,
             assigned, pledged or otherwise transferred any interest in such
             Shares.

     (b)     The Subsidiary Shares are validly issued, fully paid, and non-
             assessable, and are not and shall not be subject to pre-emptive
             rights, and have been issued in compliance with all state and
             federal securities laws and other applicable law.

     (c)     The execution, delivery, and performance of this Agreement by CAE
             has been duly authorized by all necessary corporate action, and
             this Agreement, upon its execution by the parties, will constitute
             the valid and binding obligation of CAE enforceable against it in
             accordance with its terms, except as enforceability may be affected
             by bankruptcy, insolvency or other laws of general application
             affecting the enforcement of creditors' rights.  The execution and
             consummation of the transactions contemplated by this Agreement
             and compliance with its provisions by CAE will not violate any
             provision of law and will not conflict with or result in any breach
             of any of the terms, conditions, or provisions of, or constitute a
             default under, CAE's or any of the Subsidiary's Certificates of
             Incorporation, or any of their Bylaws, in each case as amended, or,
             in any material respect, any indenture, lease, loan agreement or
             other agreement or instrument to which CAE or any Subsidiary is a
             party or by which it or any of its properties are bound, or any
             decree, judgment, order, statute, rule or regulation applicable to
             CAE or any Subsidiary.

     (d)     No consent, waiver, approval, order or authorization of, or
             registration, declaration or filing with, any court, administrative
             agency or commission or other federal, state, county, local or
             other foreign governmental authority, instrumentality, agency or
             commission or any third party, including a party to any agreement
             with CAE or any Subsidiary, is required in connection with the
             execution and delivery of this Agreement or the consummation of the
             transactions contemplated hereby, except for such consents,
             waivers, approvals, orders, authorizations, registrations,
             declarations and filings as may be required under applicable
             securities laws.

     (e)     Upon due endorsement and delivery of the stock certificates for the
             Subsidiary Shares at the Closing, title to the Subsidiary Shares,
             including all of CAE's right, title and interest therein, shall
             vest in the Shareholders, free and clear of all liens, claims,
             charges or encumbrances of any kind.

             inaccurate.

     (b)     amend the Certificate of Incorporation or Bylaws or any Subsidiary;
