Re: Amended and Restated Selling Agreement (the “Agreement”)

Dear Mr. Morel:

This Agreement is intended to amend and restate in its entirety the Selling Agreement by and between Lifesciences Opportunities Incorporated, a Florida corporation (the “Seller”) and Dawson James Securities, Inc. (“Selling Agent”) dated February 27, 2008.

The Seller proposes to offer and sell (the “Offering”), to selected investors, upon the terms set forth herein and in the Confidential Private Placement Memorandum dated March 31, 2008 (which collectively, together with the attachments and exhibits thereto, is referred to as the “Offering Document”), a copy of which has been delivered to you, up to 8,000 Units ($800,000) on an all-or-none basis, although the Company may accept subscriptions for up to an additional 2,000 Units ($200,000), in its sole discretion (“Maximum Offering Amount”). The initial closing will not occur until a minimum of 8,000 Units has been sold. Each Unit consists of a convertible debenture in the principal amount of $1,000 (the “Debentures”) and one thousand (1,000) shares (the “Additional Shares”) of the Company’s common stock, par value $.0001 (“Common Stock”). The Debentures and the Additional Shares being offered are sometimes referred to herein as the “Offered Securities.”

Selling Agent agrees to offer and sell the Offered Securities on an exclusive basis during the period in which the Units are being offered (the “Offering Period”). Capitalized terms used and not otherwise defined herein shall have the respective meanings set forth in the Offering Document. It is intended that the offer, offer for sale and sale of the Offered Securities will be made only to “accredited investors” (as such term is defined in Rule 501(a) of Regulation D of the Securities Act of 1933, as amended (the “1933 Act”) and will be exempt from the federal registration requirements of the 1933 Act, pursuant to Regulation D promulgated under Section 3(b) and/or Section 4(2), respectively, of the 1933 Act and will qualify for an exemption from registration, if necessary, under the applicable state securities laws and regulations.

The Seller hereby confirms its agreement with Selling Agent as follows:

1.Offer and Sale of Offered Securities by Selling Agent; Compensation; Closing.

1.1On the basis of Selling Agent’s representations, covenants and warranties, the Seller appoints Selling Agent the exclusive agent of the Seller for the period commencing on the date of the completion of the Offering Document and ending on the earlier of the date on which the Seller’s Board of Directors and the Selling Agent mutually agree to close the Offering or the Maximum Offering Amount is obtained and the subscriptions therefor have been accepted by Seller (“Offering Termination Date”), to use Selling Agent’s best efforts to offer and sell, on the terms and conditions set forth in this Agreement and in the Offering Document, subject only to Selling Agent’s right to engage participating broker-dealers pursuant to Section 2 hereof. The Selling Agent hereby accepts such appointment and agrees pursuant to the terms and conditions set forth herein and in the Offering Document to use its best efforts to offer and sell the Offered Securities as agent for the Seller during the period specified above, and to attempt to find suitable accredited purchasers for the Offered Securities acceptable to the Seller.

1.2Prior to and subject to the closing, subscription proceeds from the sale of the Offered Securities will be deposited in an escrow account with an escrow agent to be mutually agreeable to Seller and the Selling Agent (the “Escrow Agent”). The Seller will be responsible for setting up the Escrow Account, pursuant to an escrow agreement among the Seller, the Selling Agent and the Escrow Agent, which escrow agreement will be approved by the Selling Agent. Subscribers will be instructed to make their checks payable to the Escrow Agent for the benefit of Lifesciences Opportunities Incorporated, or shall cause the wire transfer of immediately available funds in favor of the Escrow Agent for Lifesciences Opportunities Incorporated, in accordance with instructions provided by the Selling Agent. At the end of the Offering Period (as the same may be extended by the mutual agreement of the Selling Agent and the Seller), a closing (the “Closing”) will occur as soon as possible after subscriptions have been accepted by the Seller and all other conditions precedent to closing have occurred to the sole satisfaction of the Selling Agent.

1.3For purposes hereof, the Offered Securities shall not be deemed to have been sold unless (x) subscription agreements, completed and fully executed by subscribers who are accredited investors have been received covering the Offered Securities; (y) all checks, drafts and wire transfers submitted by such subscribers in payment of the purchase price of such Offered Securities have been received by the Escrow Agent and have cleared so that there are “good funds” in the Escrow Account at least equal to the aggregate purchase price of the Offered Securities; and (z) the minimum offering amount of $800,000 has been obtained and received by the Escrow Agent.

1.4As compensation for the Selling Agent’s services hereunder, the Seller shall pay to Selling Agent in cash a selling commission (“Commission”) upon the Closing, in an amount equal to ten percent (10%) of the aggregate offering price of the Offered Securities sold by the Selling Agent or its authorized agent at such Closing. At the Closing of the Offering, the Seller shall pay the Selling Agent its Commission relating to the sale of the Offered Securities that are subject of the Closing provided that the Seller or counsel for the Seller has received all documents, including but not limited to, an executed Subscription Agreement for each investor (“Subscription Documents”) previously furnished to Selling Agent which the Selling Agent is required to deliver to the Seller or counsel for the Seller prior to Closing. All or any portion of such Commission may be re-allowed to Participating Broker-Dealers (as hereinafter defined). No Offered Securities shall be considered to have been sold by Selling Agent or any Participating Broker-Dealer selected by Selling Agent unless the purchaser is acceptable to the Seller, and no compensation will be payable with respect to any agreement for the purchase of Offered Securities if the Subscription Agreement therefor is not actually accepted by the Seller. Anything in this Agreement to the contrary notwithstanding, the Seller shall not be required to pay a Commission to Selling Agent and Selling Agent shall not be entitled to a Commission, pursuant to this Section 1.4 or any other provision, if to do so would cause the Seller to violate federal or state securities laws, regulations or rules or any other law applicable to the Offering.

2

1.5The Seller will pay all of its costs relating to the Offering contemplated hereby, including, without limitation, audit expenses, issuance costs and taxes, counsel fees for the preparation of the Offering Documents, filing fees and disbursements of counsel relating to the qualification of the Offered Securities under federal securities laws, and legal fees and expenses of counsel in connection with qualifying the Offered Securities under the state blue sky laws. To the extent required by law, the Seller shall qualify the Offered Securities for offer and sale in those jurisdictions designated by the Selling Agent and reasonably acceptable to the Seller. The Seller’s counsel shall be responsible for state blue sky securities laws compliance by the Seller.

1.6[Intentionally deleted].

1.7Once the Offered Securities are sold, or the Offering Period terminates, the agency between the Seller and the Selling Agent shall terminate. The Selling Agent, on the basis of the representations and warranties herein contained, but subject to the terms and conditions herein set forth, accepts such appointment as the limited agent of the Seller and agrees to use its best efforts to find purchasers for the Offered Securities.

1.8Upon the Closing of the sale of the Offered Securities offered by the Seller hereunder, the Seller will issue to the Selling Agent at a purchase price of $.001 per warrant, warrants to purchase shares of Common Stock equal to 10% of the Additional Shares contained in the Units sold by Selling Agent or Participating Broker-Dealers in the Offering (“Selling Agent’s Warrants”). The Selling Agent’s Warrants shall be exercisable at any time during the five (5) years from the date of Closing at an exercise price equal to $1.00 per share of Common Stock and shall have piggy-back registration rights. The Selling Agent’s Warrants shall be in the form and shall contain the provisions set forth in Exhibit A attached hereto.

1.9The Closing(s) shall be held at the offices of the Selling Agent, 925 S. Federal Highway, 6^th Floor, Boca Raton, FL 33432, or in an alternative location and at such time and date as Selling Agent and the Seller may mutually agree.

1.10 The holders of the Offered Securities will be provided with registration rights as set forth in the Offering Document with respect to the shares of Common Stock underlying the Debentures and the Additional Shares. The Additional Shares shall also be subject to the terms of the lock-up agreement as set forth in the Offering Document.

2.Participating Broker-Dealers. The Seller hereby authorizes Selling Agent to engage other qualified broker-dealers (the “Participating Broker-Dealers”) to assist the Selling Agent in the placement of the Offered Securities; provided that during all times that each such Participating Broker-Dealer shall offer and sell the Offered Securities, each such Participating Broker-Dealer shall be registered as a broker-dealer under the Securities Exchange Act of 1934 (the “1934 Act”), shall be a member in good standing of the Financial Industry Regulatory Authority (“FINRA”), and shall be authorized to offer and sell the Offered Securities under the laws of the jurisdictions in which the Offered Securities will be offered and sold by such Participating Broker-Dealer. All Participating Broker-Dealers will be required to execute a Participating Broker-Dealer Agreement, the form of which is subject to the reasonable approval of the Seller, with Selling Agent containing substantially the same terms and conditions as this Agreement, including, without limitation, the representations and warranties contained in Section 3.2 below and provisions for indemnification of the Seller to the same extent as your indemnification provided in Section 7 below. Any commissions, fees, or expenses payable to such Participating Broker-Dealers will be paid by the Selling Agent and not by the Seller.
