         closing; provided, however, the Closing Date shall occur within thirty (30) days after the delivery of
         the Exercise Notice to Optionor and HA and not earlier than fifteen (15) days after the delivery of the
         Exercise Notice to Optionor and HA, time being of the essence, unless otherwise agreed to by Optionee,

                  (a)               The Company has been duly organized and is validly existing and in good
         standing under the laws of the State of Delaware, and has the requisite power and authority and all
         necessary governmental approvals to own, lease and operate its properties and to carry on its business

         standing, in each jurisdiction where the character of the properties owned, leased or operated by it or
         the nature of its business makes such qualification or licensing necessary, except where the failure to

         paid and nonassessable, will not be subject to preemptive rights and have been issued in full compliance
         with all applicable securities laws and other Legal Requirements.  There are no outstanding contractual

         granted the Enterprises Warrant to Enterprises, both in the form previously reviewed by Optionee.

                           (i)              contravene, conflict with or result in a violation of (A) any of the
                  provisions of the Company's certificate of incorporation or bylaws, or (B) any resolution

                  Company's board of directors, if any;

                  payment of, any Tax;

                  (j)               Except as set forth in the HA License Agreement, the Company is not a party to
         any agreement or license with any other party concerning the HA Intellectual Property.

                  The Company will not be required to make any filing with or give any notice to, or obtain any
         Consent from, any Person in connection with the execution and delivery of this Agreement or the
         consummation or performance of the Transaction.  As of the date hereof, all such filings, notices and
         Consents have been duly made, given or obtained and are in full force and effect, other than those which
         by their nature are required to be made, given or obtained after the execution of this Agreement, all of
         which shall be made, given or obtained within the time required therefor.

         6.       Optionor's Representations and Warranties.  Each Optionor severally warrants and represents as
of the date hereof with respect to such Optionor (with the express understanding that Optionee is relying on said
warranties, representations and covenants) that:

                  (a)               Optionor has all necessary power and authority to execute and deliver this
         Agreement, to perform its obligations under this Agreement and to consummate the Transaction and the
         other transactions contemplated by this Agreement.  The execution and delivery of this Agreement and the
         consummation by Optionor of the Transaction contemplated hereby have been duly and validly authorized by
         all necessary action, and no other proceedings on the part of the Optionor are necessary to authorize
         this Agreement or to consummate such transactions.  This Agreement has been validly executed and
         delivered by the Optionor and constitutes a legal, valid and binding obligation of the Optionor,
         enforceable against it in accordance with its terms.

                  (b)               The Optionor has legal, valid, beneficial and exclusive title to, in the case
         of Conrad, 500,000 shares of Company Common Stock, and, in the case of Enterprises, the Enterprises
         Warrant, free and clear of all Encumbrances other than those imposed by the Securities Act.

         7.       Optionee's Representations and Warranties.  Optionee warrants and represents as of the date
hereof (with the express understanding that the Optionor, the Company and Employee are relying on said
warranties, representations and covenants) that:

                  (a)               Optionee and each Subsidiary of Optionee (collectively, the "Optionee
         Subsidiaries") has been duly organized and is validly existing and in good standing under the laws of
         the jurisdiction of its incorporation or organization, as the case may be, and has the requisite power

                                                      -8-

         and authority and all necessary governmental approvals to own, lease and operate its properties and to
         carry on its business as it is now being conducted.  Each of Optionee and each Optionee Subsidiary is
         duly qualified or licensed to do business, and is in good standing, in each jurisdiction where the
         character of the properties owned, leased or operated by it or the nature of its business makes such
         qualification or licensing necessary, except where the failure to so qualify would not have a Material
         Adverse Effect on Optionee.  Schedule 7(a) sets forth a complete and correct list of all of the Optionee
         Subsidiaries.  Neither Optionee nor any Optionee Subsidiary holds any equity interest in any Person
         other than the Optionee Subsidiaries so listed.

                  (b)               Optionee has all necessary corporate power and authority to execute and
         deliver this Agreement, to perform its obligations hereunder and to consummate the Transaction and the
         other transactions contemplated hereby.  The execution and delivery of this Agreement and the
         consummation by Optionee of the Transaction and the transactions contemplated hereby have been duly and
         validly authorized by all necessary corporate action other than the approval of Optionee's stockholders
         (the "Optionee Shareholder Approval") and no other corporate proceedings on the part of Optionee are
         necessary to authorize this Agreement or to consummate such transactions, except for the Optionee
         Shareholder Approval.  This Agreement has been duly authorized and validly executed and delivered by
         Optionee and constitutes a legal, valid and binding obligation of Optionee, enforceable against it in
         accordance with its terms.

                  (c)               The representations and warranties set forth in Section 5.2 of the Merger
         Agreement are true and correct.

         8.       Covenants.

                  (a)               Until the termination of this Agreement, each Optionor agrees not to Transfer
         or otherwise Encumber the Company Common Stock, the Enterprises Warrant or the Company Common Stock
         issuable upon exercise of the Enterprises Warrant, as applicable, unless the transferee has agreed to be
         bound by the terms hereof and without the prior written consent of Optionee, which consent shall not be
         unreasonably withheld.  Notwithstanding the foregoing, Optionee's consent shall not be required with
         respect to a Transfer to an Affiliate of Optionor or as a result of a merger, change in control or the
         sale of all or substantially all of the Optionor's assets.

                  (b)               Subject to the terms and conditions provided in this Agreement and to
         applicable legal requirements, each of the parties agrees to use its best efforts to take, or cause to
         be taken, all action, and to do, or cause to be done, and to assist and cooperate with the other parties
         in doing, as promptly as practicable, all things necessary, proper or advisable under applicable laws to
         consummate and make effective the transactions contemplated by this Agreement.

                                                      -9-

         9.       Non-Performance.

                  (a)               In the event of a failure of Optionor or HA to consummate the Transaction in
         accordance with the terms hereof, Optionee may pursue, any one or all of the following remedies:

                           (i)              Terminate this Agreement;

                           (ii)             Waive such default and close;

                           (iii)            Institute an action for specific performance; and/or

                           (iv)             Pursue any other remedies available under law or in equity;

                  (b)               This Agreement shall terminate automatically if Optionee has not provided
         Optionor and HA an Exercise Notice on or prior to the Option Expiration Date, time being of the essence.

         10.      Assignment.  Except upon the prior written consent of the parties Optionee may not assign the
Option or any other right under this Agreement.

         11.      Broker.  Each of the parties hereto represents to the other that it has not retained the
services of a broker or finder in connection with this transaction.  Optionor hereby expressly agrees to
indemnify and hold Optionee harmless from and against any and all loss incurred by Optionee as a result of a
claim by any person(s) or entity(ies) for a commission claim through Optionor with respect to the transaction
contemplated by this Agreement.  HA hereby expressly agrees to indemnify and hold Optionee harmless from and
against any and all loss incurred by Optionee as a result of a claim by any person(s) or entity(ies) for a
commission claim through HA with respect to the transaction contemplated by this Agreement.  Optionee hereby
expressly agrees to indemnify and hold Optionor harmless from and against any and all loss incurred by Optionor
as a result of a claim by any person(s) or entity(ies) for a commission claim through Optionee with respect to
the transaction contemplated by this Agreement.

         respect to this transaction.  There are no oral promises, conditions, representations, understandings,

         provision hereof shall be deemed to be invalid, illegal or unenforceable, such invalidity, illegality or

         as each provision of this Agreement shall be deemed to be severable from all other provisions hereof.

                  (d)               Waivers.  The waiver of either party hereto of any right granted to it
         hereunder shall not be deemed to be a waiver of any other right granted herein, nor shall the same be

         previously waived.

                  (e)               Binding Agreement; Inurement.  This Agreement shall be binding upon and inure

         agent or of partnership or joint venture or of any association between the parties.

                  (h)               Captions.  The captions of the paragraphs hereof are for convenience only and

                  (k)               Counterparts.  This Agreement may be executed in two or more counterparts,
         each of which shall be deemed an original, and which together shall constitute but one and the same
         instrument.
