THIRD AMENDMENT

TO

BINDING LETTER OF INTENT

This Third Amendment to the Binding Letter of Intent (the Third Amendment) is entered
into this 27thday of March 2006, by and between Youth Enhancement Systems, Inc. (YES), and Amparo Arango Franco (the
Inventor).

Recitals

A. YES and the Inventor are parties to the Binding Letter of Intent dated April 8, 2003, as amended by the Amendment to the Binding Letter of Intent dated July 22, 2004, and further amended by the Second
Amendment to Binding Letter of Intent dated June 4, 2005 (collectively, the LOI). Capitalized words in this Third Amendment are intended to have the meaning set forth in the LOI, unless otherwise indicated.

B. The parties have agreed to amend and supplement the LOI in accordance with the terms contained herein.

NOW THEREFORE, the parties agree that the LOI is amended as follows:

1. The aforementioned recitals are true.

2. Subject to YES prompt and timely compliance with all of
its obligations under the LOI as amended, the Inventor hereby grants to YES an unlimited, exclusive world-wide license (the License), including without limitation the rights (i) to manufacture, distribute, market and sell the
Product/Formula, (ii) to pursue, at YES sole discretion and at its expense, claims against third parties infringing the Patent, (iii) subject to the limitations set forth herein, to sublicense the Product/Formula and (iv) to
conduct formal and informal clinical studies involving the Product/Formula./The term of the License shall be five (5) years from the date of this Third Amendment (the Term). So long as YES is in prompt and timely compliance with its obligations
hereunder, including but not limited to the timely payment of amounts due Inventor, the Inventor shall not, during the Term, manufacture, distribute, market and/or sell the Product/Formula for or to any third party. In the event of the nonpayment or
late payment of amounts due Inventor under the LOI, Inventor shall have no obligation to notify YES of such nonpayment or late payment and YES shall have no grace period or opportunity to cure, except only in the event such nonpayment or late
payment is caused by reasons outside of YES control (i.e., bank occasioned delays) in which case Inventor shall have no obligation to notify YES but payment due must be received by Inventor within 3 business days of its due date. For all
nonpayment or late payment, noncompliances or defaults under the LOI, Inventor shall first provide YES with written notice of any non-compliance or default and provide reasonable opportunity (not to exceed 30 days) to cure. Nonpayment or late
payment of amounts due Inventor, as set forth herein, shall entitle Inventor to terminate the LOI and the License, upon written notice to YES. In the event of such termination of the LOI and the License, all of YES rights regarding the
Product/Formula shall terminate and Inventor shall be free, released from and discharged from any further obligations or restrictions under the LOI.



---

3. During the Term, YES will pay for the License a monthly fee of $25,000.00 (Twenty-five Thousand
Dollars) (the Monthly License Fee). In the event that (i) YES is prohibited from selling the Product/Formula (the Prohibition) by order of a court of competent jurisdiction or by order of a governmental regulatory agency
with the authority to enforce the Prohibition (the Order); or (ii) suspends sale of the Product/Formula due to its receipt of a formal and written demand, in advance of expressed and threatened enforcement action, from a
governmental or industry regulatory agencies with the authority to enforce the Prohibition (the Demand), such that YES, after consulting with the Inventor and in an effort to forestall enforcement action and/or mitigate damages, deems it
necessary to suspend sales of the Product/Formula; the amount of the Monthly License Fee shall be reduced to $10,000.00 (Ten Thousand Dollars) (the Interim Reduced Fee) until such time as the Order or the Demand is no longer effective or
sales can be resumed, whichever occurs first. It is agreed by YES and the Inventor that YES will have the duty and obligation, as a condition of its license, to diligently challenge any attempt by any party or governmental or industry agency seeking
to institute or implement the Order or Demand, including but not limited to, the filing, prosecution and defense of civil and/or regulatory actions seeking injunctive and/or equitable relief and the posting, if necessary, of appropriate bonds.
During any suspension of sales resulting from an Order or Demand, YES shall make best efforts to pursue and generate revenues in markets not affected by the Order or Demand. There will be no reduction in the Monthly License Fee if YES is able to
sell the Product/Formula in markets anywhere in the world where such sales shall not be prohibited by the Order or Demand.

4. Each Monthly
License Fee shall be due and payable promptly on the 25th day of each month during the Term, without delay or set off.

5. At the
expiration of the Term, YES shall have the exclusive right to purchase the Product/Formula for the Purchase Price (as defined herein). The Purchase Price shall be $5,000,000.00 (Five Million Dollars) plus the Royalty (as defined below)
obligation set forth below. YES will pay the Purchase Price on or before the expiration of the Term (the Closing); provided, however, that YES will receive a credit toward the Purchase Price in an amount equal to the sum of all payments
made to the Inventor by YES since the inception of the LOI to the date of Closing. As of the date of this Third Amendment, the parties agree and acknowledge that the payments made by YES to the Inventor since the inception of the LOI totals
$667,500.00 (Six Hundred Sixty-seven Thousand Five Hundred Dollars). At Closing, the Inventor will transfer all her right, title and interest in and to the Product/Formula and all intellectual property rights associated therewith, including but not
limited to the Patent, CIP, PCT and other applications deriving from the Patent or the Product/Formula.

6. From the date of the Closing,
YES will pay to the Inventor a perpetual royalty (the Royalty) equal to one percent (1%) of YES worldwide gross sales of the Product/Formula, payable each calendar quarter. For purposes of calculating the Royalty, gross sales
of the Product/Formula shall include the sale of all products and/or services derived from the Product/Formula anywhere in the world. Inventor shall have the right to audit YES books and records to confirm accurate calculation and payment of
the Royalty. The cost of any such audits shall be borne by Inventor, except that if there is an underpayment discrepancy of 10% or greater for any



---

calendar year, YES shall reimburse Inventor for such audit. It is expressly understood and intended by the parties to the LOI that YES Royalty
obligation and Inventors right to receipt of the Royalty will survive any direct or indirect sale, transfer or other disposition of the Product/Formula by YES, it being further expressly understood that any entity or person that may, in the
future, directly or indirectly own or control the rights to sell the Product/Formula, will be subject to the Royalty obligation in favor of the Inventor. Any transaction entered into by YES that might, in any way impact on me Inventors right
to receipt of the Royalty shall be subject to Inventors prior written approval, which approval will not be withheld if the Royalty obligation to Inventor, as set forth herein, and the continued ability to pay the Royalty obligation, as
contemplated herein, is preserved.

7. The amount of monthly payments due under Section 6.b. of the LOI, accrued but unpaid as of the
date of this Third Amendment (i.e., $125,000) shall be paid to Inventor in ten (10) equal monthly payments of Twelve Thousand Five Hundred Dollars ($12,500.00) each concurrently with the first ten payments of the Monthly License Fee.

In all other requests, the LOI remains unchanged and in full force and effect.

Executed by the Parties this 27thday of March 2006.
