|Principal Amount:    $500,000.00 |  | Interest Rate:    7.350% |  | Date of Note:    December 20, 2007

PROMISE TO PAY. GEOPHARMA, INC. (Borrower) promises to pay to First Community Bank of America
(Lender), or order, in lawful money of the United States of America, the principal amount of Five Hundred Thousand & 00/100 Dollars ($500,000.00), together with interest at the rate of 7.350% per annum on the unpaid
principal balance from December 20, 2007, until paid in full. The interest rate may change under the terms and conditions of the INTEREST AFTER DEFAULT section.

PAYMENT. Borrower will pay this loan in one principal payment of $500,000.00 plus interest on April 6, 2008. This payment due on April 6,2008, will be for all principal and all accrued
interest not yet paid. In addition, Borrower will pay regular monthly payments of all accrued unpaid interest due as of each payment date, beginning January 20, 2008, with all subsequent interest payments to be due on the same day of each month
after that. Unless otherwise agreed or required by applicable law, payments will be applied first to any accrued unpaid interest; then to principal; then to any late charges; and then to any unpaid collection costs. The annual interest rate for this
Note is computed on a 365/360 basis; that is, by applying the ratio of the annual interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding.
Borrower will pay Lender at Lenders address shown above or at such other place as Lender may designate in writing.

PREPAYMENT. Borrower may pay
without penalty all or a portion of the amount owed earlier than it is due. Early payments will not, unless agreed to by Lender in writing, relieve Borrower of Borrowers obligation to continue to make payments under the payment schedule.
Rather, early payments will reduce the principal balance due. Borrower agrees not to send Lender payments marked paid in full, without recourse, or similar language. If Borrower sends such a payment, Lender may accept it
without losing any of Lenders rights under this Note, and Borrower will remain obligated to pay any further amount owed to Lender. All written communications concerning disputed amounts, including any check or other payment instrument that
indicates that the payment constitutes payment in full of the amount owed or that is tendered with other conditions or limitations or as full satisfaction of a disputed amount must be mailed or delivered to: First Community Bank of
America, Loan Operations Center, 7441 114th Avenue North Largo, FL 33777.

LATE CHARGE. If a payment is 10 days or more late, Borrower will be charged
5.000% of the unpaid portion of the regularly scheduled payment or $5.00, whichever is greater.

INTEREST AFTER DEFAULT. Upon default, including failure to
pay upon final maturity, the interest rate on this Note shall be increased to 18.000% per annum. However, in no event will the interest rate exceed the maximum interest rate limitations under applicable law.

DEFAULT. Each of the following shall constitute an event of default (Event of Default) under this Note:

Payment Default. Borrower fails to make any payment when due under this Note.

Other Defaults. Borrower fails to comply with or to perform any other term, obligation, covenant or condition contained in this Note or in any of the
related documents or to comply with or to perform any term, obligation, covenant or condition contained in any other agreement between Lender and Borrower.

Default in Favor of Third Parties. Borrower or any Grantor defaults under any loan, extension of credit, security agreement, purchase or sales agreement, or any other agreement, in favor of any other creditor or
person that may materially affect any of Borrowers property or Borrowers ability to repay this Note or perform Borrowers obligations under this Note or any of the related documents.

False Statements. Any warranty, representation or statement made or furnished to Lender by Borrower or on Borrowers behalf under this Note or the
related documents is false or misleading in any material respect, either now or at the time made or furnished or becomes false or misleading at any time thereafter.

benefit of creditors, any type of creditor workout, or the commencement of any proceeding under any bankruptcy or insolvency laws by or against Borrower.

Creditor or Forfeiture Proceedings. Commencement of foreclosure or forfeiture proceedings, whether by judicial proceeding, self-help, repossession or any other method, by any creditor of Borrower or by any
governmental agency against any collateral securing the loan. This includes a garnishment of any of Borrowers accounts, including deposit accounts, with Lender. However, this Event of Default shall not apply if there is a good faith dispute by
Borrower as to the validity or reasonableness of the claim which is the basis of the creditor or forfeiture proceeding and if Borrower gives Lender written notice of the creditor or forfeiture proceeding end deposits with Lender monies or a surety
bond for the creditor or forfeiture proceeding, in an amount determined by Lender, in its sole discretion, as being an adequate reserve or bond for the dispute.

Events Affecting Guarantor. Any of the preceding events occurs with respect to any guarantor, endorser, surety, or accommodation party of any of the indebtedness or any guarantor, endorser, surety, or accommodation
party dies or becomes incompetent, or revokes or disputes the validity of, or liability under, any guaranty of the indebtedness evidenced by this Note.

Change In Ownership. Any change in ownership of twenty-five percent (25%) or more of the common stock of Borrower.

Adverse Change. A material adverse change occurs in Borrowers financial condition, or Lender believes the prospect of payment or performance of this Note is impaired.

Insecurity. Lender in good faith believes itself insecure.

Cure Provisions. If any default, other than a default in payment is curable end if Borrower has not bean given a notice of a breach of the same provision of this Note within the preceding twelve (12) months, it
may be cured if Borrower, after receiving written notice from Lender demanding cure of such default: (1) cures the default within fifteen (15) days; or (2) If the cure requires more than fifteen (15) days, immediately initiates steps
which Lender deems in Lenders sole discretion to be sufficient to cure the default and thereafter continues and completes all reasonable and necessary steps sufficient to produce compliance as soon as reasonably practical.

LENDERS RIGHTS. Upon default, Lender may declare the entire unpaid principal balance under this Note and all accrued unpaid interest immediately due, and then

reasonable attorneys fees and legal expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), and appeals. If not prohibited by applicable law, Borrower also will pay any court costs, in
addition to all other sums provided by law.

counterclaim brought by either Lender or Borrower against the other.

the extent not preempted by federal law, the laws of the State of Florida without regard to its conflicts of law provisions. This Note has been accepted by Lender in the State of Florida.

CHOICE OF VENUE. If there is a lawsuit, Borrower agrees upon Lenders request to submit to the jurisdiction of the courts of Pinellas County, State of Florida.

DISHONORED ITEM FEE. Borrower will pay a fee to Lender of $25.00 if Borrower makes a payment on Borrowers loan and the check or preauthorized charge
with which Borrower pays is later dishonored.

RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a right of setoff in all
Borrowers accounts with Lender (whether checking, savings, or some other account). This includes all accounts Borrower holds jointly with someone else and all accounts Borrower may open in the future. However, this does not include any IRA or
Keogh accounts, or any trust accounts for which setoff would be prohibited by law. Borrower authorizes Lender, to the extent permitted by applicable law, to charge or setoff all sums owing on the indebtedness against any and all such accounts, and,
at Lenders option, to administratively freeze ell such accounts to allow Lender to protect Lenders charge and setoff rights provided in this paragraph.
