PROMISE TO PAY. Dougherty's Holdings,
Inc.; DOUGHERTY'S PHARMACY, INC.; Dougherty's Pharmacy El Paso, LLC; Dougherty's Pharmacy Humble, LLC; Dougherty's Pharmacy McAlester,
LLC; Dougherty's Pharmacy Forest Park Dallas, LLC; and Dougherty's Pharmacy Springtown, LLC ("Borrower") jointly and
severally promise to pay to First National Bank of Omaha ("Lender"), or order, in lawful money of the United States
of America, the principal amount of Four Million Seven Hundred Fifty Thousand & 00/100 Dollars ($4,750,000.00) or so much
as may be outstanding, together with interest on the unpaid outstanding principal balance of each advance. Interest shall be calculated
from the date of each advance until repayment of each advance or maturity, whichever occurs first.


 


CHOICE OF USURY CEILING AND INTEREST RATE.
The interest rate on this Note has been implemented under the "Quarterly Ceiling" as referred to in Section 303.006
of the Texas Finance Code.


 


PAYMENT. Borrower will pay this loan
in one payment of all outstanding principal plus all accrued unpaid interest on July 1, 2017. In addition, Borrower will pay regular
monthly payments of all accrued unpaid interest due as of each payment date, beginning August 1, 2016, 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 to interest, principal, and expenses owing under the Note in an order determined by Lender. Borrower will pay Lender
at Lender's address shown above or at such other place as Lender may designate in writing. Notwithstanding any other provision
of this Note, Lender will not charge interest on any undisbursed loan proceeds. No scheduled payment, whether of principal or
interest or both, will be due unless sufficient loan funds have been disbursed by the scheduled payment date to justify the payment.

VARIABLE INTEREST RATE. The interest
rate on this Note is subject to change from time to time based on changes in an independent index which is the London Interbank
Offered Rate (commonly known as "LIBOR") for U.S. Dollar Deposits published by the Wall Street Journal as the "One
(1) Month LIBOR Rate" (the "Index"). The Index is not necessarily the lowest rate charged by Lender on its loans.
If the Index becomes unavailable during the term of this loan, Lender may designate a substitute index after notifying Borrower.
Lender will tell Borrower the current Index rate upon Borrower's request. The interest rate change will not occur more often than
each first (1st) day of every month during the term of the Note. The interest rate will be adjusted and determined without notice
to Borrower using the Index as of the date that is two (2) London Banking Days prior to each interest rate change date. "London
Banking Day" means any day, other than a Saturday or Sunday, on which commercial banking institutions in London, England,
are generally open for business. At Lender's option, the Index and/or the interest rate may be rounded upwards to the next higher
one one-hundredth of one percent (0.01%). If at any time the Index is less than zero, then it shall be deemed to be zero for the
purpose of calculating the interest rate on this Note. Borrower understands that Lender may make loans based on other rates as
well. The Index currently is 0.460% per annum. Interest prior to maturity on the unpaid principal balance of this Note will be
calculated as described in the "INTEREST CALCULATION METHOD" paragraph using a rate of 3.250 percentage points over
the Index, resulting in an initial rate of 3.710% per annum based on a year of 360 days. NOTICE: Under no circumstances
will the interest rate on this Note be more than the maximum rate allowed by applicable law. For purposes of this Note, the "maximum
rate allowed by applicable law" means the greater of (A) the maximum rate of interest permitted under federal or other law
applicable to the indebtedness evidenced by this Note, or (B) the "Quarterly Ceiling" as referred in Section 303.006
of the Texas Finance Code.


 


INTEREST CALCULATION METHOD. Interest
on this Note is computed on a 365/360 basis; that is, by applying the ratio of the 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, unless such
calculation would result in a usurious rate, in which case interest shall be calculated on a per diem basis of a year of 365 or
366 days, as the case may be. All interest payable under this Note is computed using this method.


 


PREPAYMENT. Borrower may pay without
penalty all or a portion of the amount owed earlier than it is due. Prepayment in full shall consist of payment of the remaining
unpaid principal balance together with all accrued and unpaid interest and all other amounts, costs and expenses for which Borrower
is responsible under this Note or any other agreement with Lender pertaining to this loan, and in no event will Borrower ever
be required to pay any unearned interest. Early payments will not, unless agreed to by Lender in writing, relieve Borrower
of Borrower's obligation to continue to make payments of accrued unpaid interest. 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 National Bank of Omaha, Branch #042, 4500 Preston Road, Frisco, TX 75034.


 


LATE CHARGE. If a payment is 10 days
or more late, Borrower will be charged 3.000% of the regularly scheduled payment or $25.00, whichever is greater.


 


POST MATURITY RATE. The Post Maturity
Rate on this Note is the lesser of (A) the maximum rate allowed by law or (B) the rate formed by increasing the applicable interest
rate on this Note by an additional 6.000 percentage point margin ("Post Maturity Rate Margin"), with the Post Maturity
Rate Margin applying to each succeeding interest rate change that would have applied had there been no acceleration. Borrower
will pay interest on all sums due after final maturity, whether by acceleration or otherwise, at that rate.


 


DEFAULT. Each of the following shall constitute an event
of default ("Event of Default") under this Note: Payment Default. Borrower falls to make any payment when due under
this Note.

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,

Note or perform Borrower's obligations under this Note or any of the related documents.

or statement made or furnished to Lender by Borrower or on Borrower's behalf, or made by Guarantor, or any other guarantor, endorser,
surety, or accommodation party, under this Note or the related documents in connection with the obtaining of the loan evidenced
by this Note or any security document directly or indirectly securing repayment of this Note 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.


 


Insolvency. The dissolution or termination
of Borrower's existence as a going business, the insolvency of Borrower, the appointment of a receiver for any part of Borrower's
property, any assignment for the 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 and 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.


 


Execution; Attachment. Any execution or attachment
is levied against the Collateral, and such execution or attachment is not set aside, discharged or stayed within thirty (30) days
after the same is levied.


 


Change in Zoning or Public Restriction. Any
change in any zoning ordinance or regulation or any other public restriction is enacted, adopted or implemented, that limits or
defines the uses which may be made of the Collateral such that the present or intended use of the Collateral, as specified in the
related documents, would be in violation of such zoning ordinance or regulation or public restriction, as changed.


 


Default Under Other Lien Documents. A default
occurs under any other mortgage, deed of trust or security agreement covering all or any portion of the Collateral.


 


Judgment. Unless adequately covered by insurance
in the opinion of Lender, the entry of a final judgment for the payment of money involving more than ten thousand dollars ($10,000.00)
against Borrower and the failure by Borrower to discharge the same, or cause it to be discharged, or bonded off to Lender's satisfaction,
within thirty (30) days from the date of the order, decree or process under which or pursuant to which such judgment was entered.


 


Events Affecting Guarantor. Any of the preceding
events occurs with respect to any Guarantor, or any other guarantor, endorser, surety, or accommodation party of any of the indebtedness
or any Guarantor, or any other 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, and Lender believes in good faith that the prospect of payment or performance of this Note is
impaired.

LENDER'S RIGHTS. Upon default, Lender
may declare the entire indebtedness, including the unpaid principal balance under this Note, all accrued unpaid interest, and
all other amounts, costs and expenses for which Borrower is responsible under this Note or any other agreement with Lender pertaining
to this loan, immediately due, without notice, and then Borrower will pay that amount.


 


ATTORNEYS' FEES; EXPENSES. Lender may
hire an attorney to help collect this Note if Borrower does not pay, and Borrower will pay Lender's reasonable attorneys' tees.
Borrower also will pay Lender all other amounts Lender actually incurs as court costs, lawful fees for filing, recording, releasing
to any public office any instrument securing this Note; the reasonable cost actually expended for repossessing, storing, preparing
for sale, and selling any security; and fees for noting a lien on or transferring a certificate of title to any motor vehicle
offered as security for this Note, or premiums or identifiable charges received in connection with the sale of authorized insurance.


 


JURY WAIVER. Lender and Borrower hereby
waive the right to any jury trial in any action, proceeding, or counterclaim brought by either Lender or Borrower against the
other.


 


GOVERNING LAW. This Note will be governed
by federal law applicable to Lender and, to the extent not preempted by federal law, the laws of the State of Texas without regard
to its conflicts of law provisions. This Note has been accepted by Lender in the State of Texas.


 


CHOICE OF VENUE. If there is a lawsuit,
and if the transaction evidenced by this Note occurred in Collin County, Borrower agrees upon Lender's request to submit to the
jurisdiction of the courts of Collin County, State of Texas.


 


DISHONORED CHECK CHARGE. Borrower will
pay a processing fee of $30.00 if any check given by Borrower to Lender as a payment on this loan is dishonored.


 


RIGHT OF SETOFF. After an Event of
Default, and 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 all
such accounts to allow Lender to protect Lender's charge and setoff rights provided in this paragraph.


 


COLLATERAL. Borrower acknowledges this
Note is secured by a Commercial Security Agreement dated July 1, 2016, and any and all other security agreements or documents
and any and all other collateral agreements or documents associated with this Loan or Note whether now existing or hereafter arising.


 


LINE OF CREDIT. This Note evidences
a revolving line of credit. Advances under this Note may be requested either orally or in writing by Borrower or as provided in
this paragraph. Lender may, but need not, require that all oral requests be confirmed in writing. All communications, instructions,
or directions by telephone or otherwise to Lender are to be directed to Lender's office shown above. Borrower agrees to be liable
for all sums either: (A) advanced in accordance with the instructions of an authorized person or (B) credited to any of Borrower's
accounts with Lender. The unpaid principal balance owing on this Note at any time may be evidenced by endorsements on this Note
or by Lender's internal records, including daily computer print-outs. Lender will have no obligation to advance funds under this
Note if: (A) Borrower or any guarantor is in default under the terms of this Note or any agreement that Borrower or any guarantor
has with Lender, including any agreement made in connection with the signing of this Note; (B) Borrower or any guarantor ceases
doing business or is insolvent; (C) any guarantor seeks, claims or otherwise attempts to limit, modify or revoke such guarantor's
guarantee of this Note or any other loan with Lender; (D) Borrower has applied funds provided pursuant to this Note for purposes
other than those authorized by Lender; or (E) Lender in good faith believes itself insecure. This revolving line of credit shall

FINANCIAL STATEMENTS. Borrower agrees
to provide Lender with such financial statements and other related information at such frequencies and in such detail as Lender
may reasonably request.


 


ERRORS AND OMISSIONS. Borrower agrees,
if requested by Lender, to fully cooperate in the correction, if necessary, in the reasonable discretion of Lender of any and
all loan closing documents so that all documents accurately describe the loan between Lender and Borrower. Borrower agrees to
assume all costs including by way of illustration and not limitation, actual expenses, legal fees and marketing losses for failing
to reasonably comply with Lender requests within thirty (30) days.


 


U.S.A. PATRIOT ACT. To help the government
fight the funding of terrorism and money laundering activities, the USA PATRIOT Act requires all banks to obtain and verify the
identity of each person or business that opens an account. When Borrower opens an account Lender will ask Borrower for information
that will allow Lender to properly identify Borrower and Lender will verify that information. If Lender cannot properly verify
identity within 30 calendar days, Lender reserves the right to deem all of the balance and accrued interest due and payable immediately.


 


ELECTRONIC COPIES. Lender may copy,
electronically or otherwise, and thereafter destroy, the originals of this Agreement and/or Related Documents in the regular course
of Lender 's business. All such copies produced from an electronic form or by any other reliable means (i.e., photographic image
or facsimile) shall in all respects be considered equivalent to an original, and Borrower hereby waives any rights or objections
to the use of such copies.


 


CROSS DEFAULT. An Event of Default,
beyond the applicable cure period, if any, or an Event of Default under any other Loan or any Related Document will constitute
an Event of Default under this Agreement and a default and an Event of Default under any other agreement by Borrower or any affiliate
or subsidiary of Borrower with or in favor of Lender and under any evidence of any Loan or Indebtedness held by Lender, whether
or not such is specified therein. Borrower acknowledges that some Loan Documents will be preprinted forms and that it is the intent
of Borrower and Lender that all Loans and Guaranties by Borrower or any affiliate or subsidiary of Borrower with or in favor of
Lender be cross-defaulted with each other.


 


CONSENT TO PARTICIPATION. Borrower
agrees and consents to Lender's sale or transfer, whether now or later, or one or more participation interest in this loan to
one or more purchasers, whether related or unrelated to Lender. Lender may provide, without any limitation whatsoever, to any
one or more purchasers, or potential purchasers, any information or knowledge Lender may have about Borrower or about any other
mailer relating to the Loan, and Borrower hereby waives any rights to privacy it may have with respect to such matters. Borrower
additionally waives any and all notices of sale of participation interest, as well as all notices of any repurchase of such participation
interests. Borrower also agrees that the purchasers of any such participation interest will be considered as the absolute owners
of such interests in the Loan and will have all the rights granted under the participation agreement or agreements governing the
sale of such participation interests. Borrower further waives all rights of offset or counterclaim that it may have now or later
against Lender or against any purchaser of such a participation interest and unconditionally agrees that either Lender or such
purchaser may enforce Borrower's obligation under the Loan irrespective of the failure or insolvency of any holder of any interest
in the Loan. Borrower further agrees that the purchaser of any such participation interests may enforce its interest irrespective
of any personal claims or defenses that Borrower may have against Lender.


 


FARM SERVICE AGENCY (FSA) LOAN REQUIREMENT.
If this is an FSA Loan, then it shall be an event of default if any loan proceeds are used for a purpose that will contribute to
excessive erosion of highly erodible land or  the conversion of wetland to produce or to make possible tile production of an agricultural
commodity, further explained in 7 CFR Part 1940. Subpart G, Exhibit M.


 


RENEWAL AND EXTENSION. This Note is
given in renewal and extension and not in novation of the following described indebtedness: This Promissory Note is a modification,
amendment, renewal, or replacement of the terms and conditions of indebtedness of Borrower as set forth in a Promissory Note dated
June 1, 2015, and shall include all renewals, modifications and extensions of such documents.

SUCCESSOR INTERESTS. The terms of this
Note shall be binding upon Borrower, and upon Borrower's heirs, personal representatives, successors and assigns, and shall inure
to the benefit of Lender and its successors and assigns.


 


GENERAL PROVISIONS. If any part of this
Note cannot be enforced, this fact will not affect the rest of the Note. Borrower does not agree or intend to
pay, and Lender does not agree or intend to contract for, charge, collect, take, reserve or receive (collectively referred to herein
as "charge or collect"), any amount in the nature of interest or in the nature of a fee for this loan, which would in
any way or event (including demand, prepayment, or acceleration) cause Lender to charge or collect more for this loan than the
maximum Lender would be permitted to charge or collect by federal law or the law of the State of Texas (as applicable). Any such
excess interest or unauthorized fee shall, instead of anything stated to the contrary, be
applied first to reduce the principal balance of this loan, and when the principal has been paid in full, be refunded to Borrower.
The right to accelerate maturity of sums due under this Note does not include the right to accelerate any interest which has not
otherwise accrued on the date of such acceleration, and Lender does not intend to charge or collect any unearned interest in the
event of acceleration. All sums paid or agreed to be paid to Lender for the use, forbearance or detention of sums due hereunder
shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of the
loan evidenced by this Note until payment in full so that the rate or amount of interest on account of the loan evidenced hereby
does not exceed the applicable usury ceiling. Lender may delay or forgo enforcing any of its rights or remedies under this Note
without losing them. Each Borrower understands and agrees that, with or without notice Borrower, Lender may with respect to any
other Borrower (a) make one or more additional secured or unsecured loans or otherwise extend additional credit; (b) alter, compromise,
renew, extend, accelerate, or otherwise change one or more times the time for payment or other terms of any indebtedness, including
increases and decreases of the rate of interest on the indebtedness; (c) exchange, enforce, waive, subordinate, fail or decide
not to perfect, and release any security, with or without the substitution of new collateral; (d) apply such security and direct
the order or manner of sale thereof, including without limitation, any non-judicial sale permitted by the terms of the controlling
security agreements, as Lender in its discretion may determine; (e) release, substitute, agree not to sue, or deal with any one
or more of Borrower's sureties, endorsers, or other guarantors on any terms or in any manner Lender may choose; and (f) determine
how, when and what application of payments and credits shall be made on any other indebtedness owing by such other Borrower. Borrower
and any other person who signs, guarantees or endorses this Note to the extent allowed by law, waive presentment, demand for payment,
notice of dishonor, notice of intent to accelerate the maturity of this Note, and notice of acceleration of the maturity of this
Note. Upon any change in the terms of this Note, and unless otherwise expressly stated in writing, no party who signs this Note,
whether as maker, guarantor, accommodation maker or endorser, shall be released from liability. All such parties agree that Lender
may renew or extend (repeatedly and for any length of time) this loan or release any party or guarantor or collateral; or impair,
fail to realize upon or perfect Lender's security interest in the collateral without the consent of or notice to anyone. All such
parties also agree that Lender may modify this loan without the consent of or notice to anyone other than the party with whom the
modification is made. The obligations under this Note are joint and several.
