faithfully perform the Employee's duties to the best of the Employee's ability
and in accordance with the directions of the Employer, at all times exercising
the Employee's best business judgement. The Employee shall devote such amount of
working time, attention and energies as the Employee deems necessary and

Employee shall not be required to maintain specific working hours beyond the
period as interim President. In addition to the duties assigned to the Employee
by the Employer during the Employment period, the Employee shall perform such
other duties as are commensurate with the Employee's position and title,
including, by way of illustration and not in limitation, overseeing the overall
management of the Employer's Company with specific emphasis on the research,
development and manufacturing activities of the Employer and furnishing to the
Employer the Employee's best advice, information, judgement and knowledge with
respect to the operations of the Employer's businesses.

         2.       EMPLOYMENT TERM.

                  (a) "The Employment Period" shall be a period of twenty four
(24) months from the date of effectiveness of this Agreement which is first day
of January, 2003 and any extensions of such period.

                  (b) At least ninety (90) days prior to the expiration of the
initial Employment Period or any Renewal Period as that term is hereinafter

of the employment Period, submit in writing notification of his acceptance of
the Employer's offer to extend the Employment Period. Failure of the Employer to

hereof shall result in the automatic extension of this Agreement for one (1)
year with all the same terms and provisions hereof, except that the Base Salary
(as defined in Section 3(a) below) shall be increased pursuant to Section 3(a).

                  (c) In the event of the Employee's death prior to the

the date of his resignation shall become due and payable upon the date of his
resignation.

                  (e) The Board of Directors of the Company may elect to

Employee of the Employee's obligations under this Agreement which are
demonstrably willful and deliberate on the Employee's part and which are not
remedied in a reasonable period of time after receipt of written notice by the
Employee from the Company, or (iii) the conviction of the Employee by a court of
competent jurisdiction of a felony crime. The determination of Cause shall be
made by the Board of Directors of the Company (the "Board") at a meeting of the
Board called and held for such purpose, where the Employee shall be provided
reasonable written notice of such meeting and of the acts or omissions alleged
to constitute "Cause," and shall have an opportunity to address the Board in
person regarding the acts or omissions of which he is accused. Any termination
for Cause shall be made in writing to the Employee by the Board, which notice
shall set forth in detail all acts or omissions upon which the Company is
relying for such termination.

Employer for any reason other than for Cause or the Employee's death or total

                  CONVERTIBLE UNSECURED DEMAND PROMISSORY NOTE

                                                              September 27, 2002

         FOR VALUE RECEIVED, the undersigned, PILOT THERAPEUTICS HOLDINGS, INC.,
a Delaware corporation (the "COMPANY"), having an address at 101 N. Chestnut
Street, Suite 102, Winston-Salem, North Carolina 27101, attention: Floyd "Ski"
Chilton III, PhD., President, Chief Executive Officer and Chief Scientific
Officer, hereby promises to pay to the order of Academy Centennial Fund, LLC
(the "LENDER"), at such place as the Lender may designate by written notice to
the Company, the principal sum of SEVENTY-FIVE THOUSAND DOLLARS ($75,000) plus
interest on the principal balance hereof at a per annum rate of 5.0%, Unless
this Note is earlier redeemed, the principal amount of this Note and all accrued
interest thereon shall be payable on the earlier of (i) December 31, 2002 or
(ii) the Lender's demand for payment in a written notice delivered to the
Company which specifies the date of payment.

         So long as any principal of this Note or any accrued interest thereon
remains unpaid, the Lender shall have the right to notify the Company, in
writing, that it wants to convert all or a portion of the principal of this Note
and accrued interest thereon into restricted shares of common stock of the
Company at a conversion price equal to $3.00 per common share (the "Conversion
Notice"). Upon receipt of a Conversion Notice, the Company shall promptly issue
and deliver to the Lender or its designee the number of shares of restricted
common stock of the Company, calculated in accordance with the immediately
preceding sentence, set forth in the Conversion Notice.

         This Note is subject to prepayment in whole or in part at the option of
the Company at any time, upon not less than 5 days' prior written notice
delivered to the Lender, at a price equal to the then outstanding principal
amount hereof, plus accrued interest to the date of prepayment. In the event
that the Company shall make a partial prepayment hereof, the Company shall
prepay such principal amount hereof as set forth in such notice, together with
interest accrued thereon to the date of prepayment.

         Nothing contained herein shall require the Company to pay, or the
Lender to accept, interest in an amount which would subject the Lender to any
penalty or forfeiture under applicable law. Notwithstanding that it is not
intended hereby to charge interest at a rate in excess of the maximum legal rate
of interest permitted to be charged to the Company under applicable law, if
interest in excess of such maximum legal rate shall be payable hereunder, then
ipso facto such rate shall be reduced to the highest lawful rate so that no
amounts shall be charged which are in excess thereof, and, in the event it
should be determined that any excess over such highest lawful rate has been
received, such excess shall be applied by the Lender in reduction of the
outstanding principal indebtedness on this Note.

         In the event any one or more of the provisions contained in this Note
shall for any reason be held to be invalid, illegal or unenforceable in any
respect, such invalidity, illegality or unenforceability shall not affect any
other provision of this Note, but this Note shall be construed as if such
invalid, illegal or unenforceable provision had never been contained herein or
therein.

         Presentment, protest and demand, notice of demand, notice of
acceleration, notice of intent to accelerate, dishonor, nonpayment and protest
are hereby waived by all makers, sureties, guarantors and endorsers hereof. All
makers, sureties, guarantors and endorsers hereof agree that the maturity of
this Note, or any payment hereunder, may be extended from time to time without
in any way affecting the liability of such makers, sureties, guarantors or
endorsers.

<PAGE>

         The Company promises to pay all reasonable costs of collection upon
default in the payment of this Note or interest hereon when due.

         IN WITNESS WHEREOF, the Company has caused this Note to be executed by
its duly authorized officer, as of the date first written above.
