FLOATING RATE TERM NOTE

$1,500,350.00 February 9, 2012

FOR VALUE RECEIVED, Dougherty's Holdings, Inc., a Texas corporation (hereinafter referred to as “Maker”), promises to pay to the order of Cardinal Health* (the “Payee”), on the dates and in the manner provided below, the sum of ONE MILLION FIVE HUNDRED THOUSAND THREE HUNDRED FIFTY and 00/100 DOLLARS ($1,500,350.00) (the “Loan Amount”) or such lesser amount as shall be outstanding hereunder, together with interest on the unpaid principal balance hereof from the date hereof until maturity at a rate of interest per annum equal to the Prime Rate (as hereinafter defined) plus 2.75% per annum (the “Borrower Rate”). The term “Prime Rate” shall mean the rate of interest designated by SunTrust Bank (the “Bank”) from time to time as its “Prime Rate” which rate is a reference rate and not necessarily the Bank’s best rate of interest; any change in the Prime Rate shall be effective as of the date of such change.

1. Calculation of Borrower Rate; Simple Interest Disclosure.

For informational purposes, as of the date hereof, the Prime Rate is 3.25% per annum thus producing an initial Borrower Rate as of the date hereof of 6% per annum, expressed in simple interest terms. The amount of interest accruing and payable hereunder shall be calculated based on the actual number of days elapsed in a 360 day year.

2. Payments of Principal and Interest.

On the date hereof, the Loan Amount shall be amortized in equal monthly installments until maturity. The principal due on this Note shall be repaid in 59 consecutive monthly installments of principal in the amount of $17,861.31, together with all accrued and unpaid interest on the Note through such date, commencing on March 10, 2012 and continuing on the tenth day of each month thereafter through and including January 20, 2017. On February 20, 2017 (the “Maturity Date”), a balloon payment of all unpaid principal and accrued and unpaid interest under this Note shall be due and payable in full unless sooner accelerated in accordance with the terms hereof. Interest shall be calculated on the outstanding principal balance of this Note and shall be payable in arrears; provided that, in the event of any change in the Prime Rate occurring on or after the date when the Payee mails an invoice for the monthly payment amount to the Maker, any such change in the interest payment shall be reflected as an adjustment in the next monthly invoice sent to the Maker and shall not be deemed to be due and payable until that date. In no event shall any interest be charged on any unpaid interest hereunder. If any payment under this Note remains wholly or partially unpaid for more than ten (10) days after such payment was due and payable, the Maker agrees to pay a late fee equal to five percent (5%) of the payment amount which is past due, not to exceed fifty dollars ($50.00).

3. Place of Payment; Holidays.

(a)All amounts due and payable hereunder shall be paid via an automatic debit initiated by Payee from Maker's bank account.

(b)In any case where the date for any action required to be performed under this Note or any document executed in connection herewith shall be, in the city where the performance is to be made, a Saturday, a Sunday, a legal holiday or a day on which banking institutions are authorized by law to close (a “Holiday”), then such performance may be made on the next succeeding day that is not a Holiday.

4. Interest after Due Date or Event of Default.

Any principal outstanding hereunder, after the due date therefor, and whether or not due to acceleration following an Event of Default, shall bear interest at the lesser of (i) the Borrower Rate plus an additional three percent (3%) per annum or (ii) the highest rate allowed by applicable law; provided, however, that if such increase in interest is prohibited by any applicable law, interest on any amounts due hereunder after the due date therefor shall continue to be calculated at the Borrower Rate.

5. Events of Default and Remedies Upon Default.

If any “Event of Default” under the Loan Agreement (hereinafter defined) occurs (provided that Maker and Payee may enter or have entered into a loan agreement with respect to the indebtedness evidenced hereby) or if any amount due under this Note is not paid when due, or if any check tendered for any such amount is not honored and paid immediately upon presentation to the bank on which it is drawn, or if Maker fails to purchase all of its pharmaceutical (“Rx Products”) requirements from Payee, provided such Rx Products are carried by Payee, or if Maker fails fully and timely to perform or pay any other obligations under this or any other agreement or arrangement with Payee (or any other subsidiary or affiliate of Payee’s parent corporation, Cardinal Health, Inc.), including, without limitation, the breach of any term, condition, warranty or covenant under any sales, purchase or security agreement or the termination or non-renewal by Maker of any sales or purchase agreement with Payee, or if Maker becomes insolvent, commences or has commenced against it any bankruptcy or insolvency proceeding, or if any guarantor of the obligation hereby evidenced shall die or if the holder of this Note in good faith deems itself insecure with respect to any amount owed to it from Maker under this Note or otherwise, then all payments thereafter due under this Note shall become immediately due and payable at the option of the holder of this Note, without further demand or notice, and interest thereafter shall accrue upon the entire outstanding balance of this Note at the rate set forth in paragraph number 4 of this Note until this Note is paid in full. Upon this Note becoming due and payable, Payee shall be entitled to exercise all rights and remedies provided for by law. Any failure of the holder of this Note to exercise the above- described option with respect to any such nonpayment or default shall not waive or otherwise affect the holder’s rights to exercise that option with respect to that or any subsequent nonpayment or default.

6. Right to Prepay Note.

Maker shall have the right to prepay this Note, in whole or in part, at any time without penalty.

7. Costs of Collection.

If default is made in the payment of this Note and it is placed in the hands of an attorney for collection, or if collected through probate or bankruptcy proceedings, or if suit is brought on the same, Maker agrees to pay all of the Payee’s costs and expenses of collection, including without limitation, reasonable attorney’s fees and expenses, incurred as a result of the foregoing in addition to the other sums due hereunder.

8. Right of Set-Off.

The Payee or any subsequent holder hereof shall at all times have a right of set-off against any indebtedness due or to become due to Maker from the Payee (including but not limited to Payee’s affiliates, subsidiaries, parent or related entities, collectively or individually) or such holder of this Note in satisfaction of the indebtedness under this Note, without notice or demand to the Maker.

This Note shall be binding upon the successors and assigns of Maker and shall inure to the benefit of the successors and assigns of the Payee; provided, however, that Maker shall have no right to assign its rights or obligations hereunder to any person or entity without the prior written consent of the Payee. The Payee may assign this Note and all accompanying security instruments and guaranties securing the Maker’s obligations hereunder at any time to any entity.

10. Intent not to Violate Usury Laws.

It is the intent of the parties hereto not to violate any federal or state law, rule or regulation pertaining either to usury or to the contracting for or charging or collecting of interest, and each of the Payee and Maker agree that should any provision of this Note be deemed to violate any such law, rule or regulation, then the excess of interest contracted for or charged or collected over the maximum lawful rate of interest shall be applied to the principal amount due hereunder, without penalty.

11. Cumulative Remedies; Waivers by Maker.

No remedy referred to herein is intended to be exclusive, but each shall be cumulative and in addition to any other remedy available to holder, whether at law or in equity. Maker hereby waives presentment, demand for payment, protest and notice of dishonor of this Note and all other notices and demands.

12. Non-waiver.

Any default by the Maker in the Other Indebtedness shall constitute a default under the Note Indebtedness, and any default under the Note Indebtedness shall constitute a default under the Other Indebtedness, in each case permitting the holder(s) of any such Note Indebtedness or Other Indebtedness, respectively, to accelerate the payment in full of all of such Note Indebtedness or Other Indebtedness, and/or exercise any and all other rights and remedies with respect to the Credit Support.
