PROMISSORY NOTE

$94,943.00                       Conyers, Georgia                 April 30, 2000


         FOR VALUE RECEIVED, the undersigned, CYNTECH TECHNOLOGIES, INC.
("Maker"), a Utah corporation whose mailing address and principal office is 4305
Derbyshire Trace, SE, Conyers, Georgia 30094, hereby promises to pay to CENTURY
CARIBBEAN, LTD. ("Payee"), a Cayman Islands corporation whose mailing address is
c/o R. Frank Meyer, 4305 Derbyshire Trace, SE, Conyers, GA 30094, the principal
sum of Ninety-four Thousand Nine Hundred Forty-three and No/100 Dollars
($94,943.00), in lawful money of the United States of America for payment of
private debts, together with interest (calculated on the basis of the actual
number of days elapsed but computed as if each year consisted of 360 days) on
the unpaid principal balance from time to time outstanding at a rate, except as
otherwise provided in this Note, of twelve percent (12%) per annum. All past due
amounts and accrued interest thereon shall bear interest at the maximum rate
permitted under Georgia law, compounded quarterly, until paid.

         1. Payment. This Note shall be due and payable thirty (30) days after
demand, so long as demand is made after May 1, 2002.

         2. Time and Place of Payment. If any payment falls due on a day which
is considered a legal holiday in the state of Georgia, Maker shall be entitled
to delay such payment until the next succeeding regular business day, but
interest shall continue to accrue until the payment is in fact made. Each
payment or prepayment hereon must be paid at the office of Payee set forth
above, or at such other place as the Payee or other Payee may from time to time
designate in writing.

         3. Prepayment. Maker reserves the right and privilege of prepaying this
Note in whole or in part at any time, or from time to time, without notice,
premium, charge, or penalty. Prepayments on this Note shall be applied first to
accrued and unpaid interest to the date of such prepayment, next to expenses for
which Payee is due to be reimbursed under the terms of this Note, and then to
the unpaid principal balance hereof.

         4. Conversion. Subject to, and in compliance with, the provisions
contained herein, the Payee is entitled, at Payee's option, at any time prior to
maturity, to convert this Note (or any portion of the principal amount and
accrued interest hereof), into fully paid and nonassessable shares (calculated
as to each conversion to the nearest share) of common stock, par value $0.001
per share, of the Maker (the "Shares") at the rate of one share for each $1.00
of principal amount and accrued interest of this Note, subject to such
adjustment in such conversion price, if any, as may be required by the
provisions of this Note, by surrender of this Note, duly endorsed (if so
required by Maker) or assigned to the Maker or in blank, at the offices of the
Maker, accompanied by written notice to the Maker, including an Investment
Letter as described below, that the Payee elects to convert this Note or, if
less than the entire principal amount hereof and accrued interest is to be
converted, the portion hereof to be converted. No fractions of Shares shall be
converted.

         5. Investment Letters. If the Payee elects to convert this Note (or any
portion of the principal amount and accrued interest hereof), into fully paid
and nonassessable shares, the Payee shall execute an Investment Letter, in a
form acceptable to the Maker, representing that the Shares are being acquired
without a view to, or for, resale in connections with any distribution of such
Shares or any interest therein without registration under the Securities Act of
1933, and that the Payee has no direct or indirect participation in any such
undertaking or in the underwriting of such an undertaking. The Maker may refuse
to transfer the Shares if any circumstances are present reasonably indicating
that the Payee's representations are not accurate.

         6. Default. Without notice or demand (which are hereby waived), the
entire unpaid principal balance of, and all accrued interest on, this Note shall
immediately become due and payable at the option of the Payee upon the
occurrence of one or more of the following events of default ("Events of
Default"):

                  (a) The failure or refusal of Maker to pay principal of or
         accrued interest on this Note within ten (10) days of when the same
         becomes due in accordance with the terms hereof.

                  (b) The failure or refusal of Maker punctually and properly to
         perform, observe, and comply with any covenant or agreement contained
         herein, and such failure or refusal continues for a period of thirty
         (30) days after Maker has (or, with the exercise of reasonable
         investigation, should have) notice hereof.

                  (c) Maker shall (i) voluntarily seek, consent to or acquiesce
         in the benefit or benefits of any Debtor Relief Law (defined
         hereinafter), or (ii) become a party to (or be made the subject of) any
         proceeding provided for by any Debtor Relief Law, other than as a
         creditor or claimant, that could suspend or otherwise adversely affect
         the Rights (defined hereinafter) of Payee granted herein (unless, in

         department, commission, board, bureau, agency or instrumentality of the
         United States or of any state, commonwealth, nation, territory,
         possession, county, parish, or municipality, whether now or hereafter
         constituted and/or existing.

                  (d) The failure to have discharged within a period of thirty
         (30) days after the commencement thereof any attachment, sequestration
         or similar proceeding against any of the assets of Maker, or the loss,
         theft or destruction of, or occurrence of substantial damage to a
         material part of the assets of Maker, except to the extent adequately
         covered by insurance.

                  (e) Maker fails to pay any money judgment against it at least
         ten (10) days prior to the date on which any of Maker's assets may be
         lawfully sold to satisfy such judgment.

If any one or more of the Events of Default specified above shall have happened,
the Payee may, at Payee's option, (i) declare the entire unpaid balance of
principal of and accrued interest on this Note to be immediately due and payable
without notice or demand, (ii) offset against this Note any sum or sums owed by
the Payee to Maker, (iii) reduce any claim to judgment, (iv) foreclose all liens
and security interests securing payment thereof or any part thereof and/or (v)
proceed to protect and enforce its rights either by suit in equity and/or by
action of law, or by other appropriate proceedings, whether for the specific
performance of any covenant or agreement contained in this Note, or in aid of
the exercise granted by this Note, of any right, or to enforce any other legal
or equitable right or remedy of the Payee.

         7. Cumulative Rights. No delay on the part of the Payee in the exercise
of any power or right or single partial exercise of any such power or right
under this Note, or under any other instrument executed pursuant hereto shall
operate as a waiver thereof.

         8. Collection Costs. If this Note is placed in the hands of an attorney
for collection, or if it is collected through any legal proceeding at law or in
equity or in bankruptcy, receivership or other court proceedings, Maker agrees
to pay all costs of collection, including but not limited to court costs and
reasonable attorney's fees of the Payee.

         9. Waiver. Maker, and each surety, endorser, guarantor, and other party
liable for the payment of any sums of money payable on this Note, jointly and
severally waive presentment and demand for payment, protest, and notice of
protest and nonpayment, or other notice of default except as specified herein
and agree that their liability on this Note shall not be affected by any renewal

Note, before or after maturity, regardless of the number of such renewals,
extensions, indulgences, releases, or changes.

assign any rights, powers, duties, or obligations under this Note.

         12. Headings. The headings of the paragraphs of this Note are inserted
for convenience only and shall not be deemed to constitute a part hereof.

         13. Applicable Law. This Note is being executed and delivered, and is
