Attachment 1


 


Pricing Matrix


 


Purchase Price


 


Subject to Buyer’s
compliance with Section 5 of the Agreement, Buyer will be entitled to purchase branded Rx Products from Cardinal Health (that are
not Specially Priced Merchandise or subject to a Manufacturer Contract) for Buyer’s Pharmacies at a purchase price equal
to Cardinal Health’s Cost minus the applicable percentage set forth in the matrix below:


 


	Average Monthly Net Purchases	Discount [***]	Discount 

[***]	Discount [***]	Discount 

[***]
	[***]	[***]	[***]	[***]	[***]
	[***]	[***]	[***]	[***]	[***]
	[***]	[***]	[***]	[***]	[***]
	[***]	[***]	[***]	[***]	[***]
	[***]	[***]	[***]	[***]	[***]


 


At the end of each calendar quarter the
Agreement is in effect, Cardinal Health will evaluate Buyer’s average monthly Net Purchases during the calendar quarter.
If Buyer’s average monthly Net Purchases during the quarter entitles Buyer to purchase branded Rx Products at a lower (or
higher) purchase price according to the foregoing matrix than Buyer was invoiced during the quarter, then prospective adjustments
to the invoiced purchase price will be made beginning as of the first day of the second month following the end of the quarter
measured.


 


Buyer’s Purchase Price


 


Based on Buyer’s
representation that: (i) Buyer’s aggregate monthly Net Purchases from Cardinal Health under the Agreement shall be at least
[***], and (ii) Buyer’s aggregate monthly Net Purchases under the Agreement of generic Rx Products through the Generic Source
Program shall equal at least [***], each of the Buyer's individual Pharmacy locations will initially be invoiced at Cardinal Health's
Cost Minus the applicable percentage in the [***] pricing tier set forth in the pricing matrix above. For example, if a given Pharmacy
location pays in accordance with the [***] payment terms, the Buyer's initial purchase price for the Pharmacy location shall be
[***].


 


Exceptions to the Foregoing Pricing



 


Notwithstanding the
foregoing, as set forth in Section 4 of the Agreement, the purchase price for Specially Priced Merchandise shall not be based upon
Cardinal Health’s [***] pricing in accordance with this Pricing Matrix, but instead will be net-billed in accordance with
the terms and conditions established by Cardinal Health (including applicable mark-up) for such Merchandise. As also set forth
in Section 4 of the Agreement, the purchase price of Merchandise that is subject to a Manufacturer Contract will equal Buyer’s
contract price for the applicable Merchandise as set forth in the Manufacturer Contract.


 


GPO Administrative Fees 


 


The pricing specified
in the Pricing Matrix above does not reflect any administrative fees for membership in any group purchasing organization (a “GPO”).
If Buyer or any Pharmacy affiliates with a GPO, the appropriate administrative fee will be added to the percentages specified in
the Pricing Matrix.

Monthly Source Rebate


 


In General.  Subject
to the limitations set forth below:


 


Cardinal Health shall pay the Buyer a monthly
rebate (the “Monthly Source Rebate”) based on the Buyer’s retail Pharmacies’ aggregate Net Purchases
of Merchandise through the Source Program during the applicable calendar month, including, but not limited to, those generic Rx
Products purchased through the Generic Source Program. The Monthly Source Rebate shall be calculated by Cardinal Health for each
full calendar month the Agreement is in effect and shall be provided by Cardinal Health to the Buyer, if applicable, within [***]
days after the end of the applicable month via check, EFT, or in the form of a credit memorandum to be used by the Buyer towards
future purchases of Merchandise under the Agreement as mutually agreed upon by the parties. The amount of a given Monthly Source
Rebate shall be determined as follows:


 


If the Buyer’s
retail Pharmacies’ aggregate Net Purchases of Merchandise through the Source Program are less than [***] of [***] (the Buyer’s
“Monthly Source Compliance”), the Buyer’s Monthly Source Rebate shall equal [***] of the Buyer’s
retail Pharmacies’ aggregate Net Purchases through the Source Program during the applicable month.


 


However, if the Buyer’s
retail Pharmacies’ aggregate Net Purchases of Merchandise through the Source Program during the applicable month are [***]
or greater of the Buyer's retail Pharmacies' aggregate Net Purchases of Rx Products from Cardinal Health under the Agreement during
the same month (the Buyer's "Monthly Source Compliance"), the Buyer’s Monthly Source Rebate for the month
shall be determined in accordance with the following table:


 


	Retail Pharmacies' Monthly Net Purchases Through the Source Program	Monthly Source Rebate (As a Percentage of the Buyer’s Retail Pharmacies’ Net Purchases through the Source Program During the Applicable Month)
	[***]	[***]
	[***]	[***]
	[***]	[***]
	[***]	[***]
	[***]	[***]
	[***]	[***]
	[***]	[***]
	[***]	[***]
	[***]	[***]
	[***]	[***]
	[***]	[***]
	[***]	[***]
	[***]	[***]
	[***]	[***]
	[***]	[***]


 


In calculating a given Monthly Source Rebate,
the percentages set forth in the rebate tiers above shall be cumulative. For example, the portion of the Pharmacies' Monthly Source
Rebate for the first [***] purchased through the Source Program during the applicable month shall equal [***] (or [***]), and the
portion of a Monthly Source Rebate for those purchases through the Source Program from [***] through [***] shall equal [***] (or
[***]). Therefore, if the Pharmacies' aggregate Net Purchases through the Source Program equaled [***]during a given month, the
Monthly Source Rebate would equal [***].


 





Limitations.
As set forth above, the parties hereby specifically acknowledge and agree that the following Generic Source Program Products may
be excluded from the calculation of the Monthly Source Rebate: (i) exclusive generic Rx Products, (ii) biogeneric products, and
(iii) branded generic Rx Products.

be provided by Cardinal Health to the Buyer, if applicable, within [***] days after the end of the applicable month via check,
EFT, or in the form of a credit memorandum to be used by the Buyer towards future purchases of Merchandise under the Agreement

Repayment of the Prior Prepayment of a Portion of the Monthly
Source Rebate and Monthly Source Compliance Rebate


 


Buyer and Cardinal
Health were parties to that certain First Amendment which was effective as of May 1, 2015 (the “First Amendment”).
Under the First Amendment, Cardinal Health paid the Buyer a Prepayment of a Portion of the Monthly Source Rebate and Monthly Source
Compliance Rebate in the amount of [***] (the “First Amendment Prepayment of a Portion of the Monthly Source Rebate and
Monthly Source Compliance Rebate”) on the Buyer’s future purchases of merchandise from Cardinal Health under the
Agreement. The First Amendment obligated the Buyer to repay to Cardinal Health the unearned portion of the First Amendment Prepayment
of a Portion of the Monthly Source Rebate and Monthly Source Compliance Rebate if the Agreement was terminated prior to the date
upon which Buyer fully earned the First Amendment Prepayment of a Portion of the Monthly Source Rebate and Monthly Source Compliance
Rebate in accordance with the terms of the First Amendment and the Agreement, as applicable. The parties hereby acknowledge and
agree that as of the Effective Date of this Second Amendment, [***] of the First Amendment Prepayment of a Portion of the Monthly
Source Rebate and Monthly Source Compliance Rebate remains unearned by the Buyer, and the parties desire to confirm the Buyer’s
repayment obligations with respect to such unearned amount. It is the parties’ intention that the Buyer shall continue to
earn the First Amendment Prepayment of a Portion of the Monthly Source Rebate and Monthly Source Compliance Rebate on the basis
of the Buyer’s purchases from Cardinal Health under the Agreement.


 


Therefore, notwithstanding
any other provision in this Second Amendment or the Agreement, if applicable, if the Agreement is terminated for any reason prior
to April 30, 2018, the Buyer shall repay to Cardinal Health the unearned portion of the First Amendment Prepayment of a Portion
of the Monthly Source Rebate and Monthly Source Compliance Rebate, which amount shall be determined by calculating the difference
between [***] and the aggregate amount of the Monthly Source Rebate and the Monthly Source Compliance Rebate earned by Buyer under
the Agreement through the effective date of termination (the “First Amendment Prepayment of a Portion of the Monthly Source
Rebate and Monthly Source Compliance Rebate Repayment Amount”). If applicable, the Buyer shall pay such First Amendment
Prepayment of a Portion of the Monthly Source Rebate and Monthly Source Compliance Rebate Repayment Amount to Cardinal Health within
[***] days after the effective date of such termination. The parties agree, and Buyer acknowledges, that the First Amendment Prepayment
of a Portion of the Monthly Source Rebate and Monthly Source Compliance Rebate Repayment Amount has been negotiated in good faith
and is not intended as a penalty.


 


Disclosure.
The First Amendment Prepayment of a Portion of the Monthly Source Rebate and Monthly Source Compliance Rebate Repayment Amount
constitutes a “discount or other reduction in price,” as such terms are defined under the Medicare/Medicaid Anti-Kickback
Statute, on the applicable products purchased by Buyer under the Agreement. Cardinal Health and Buyer agree to use commercially
reasonable efforts to comply with any and all requirements imposed on sellers and buyers, respectively, under 42 U.S.C. §
1320a-7b(b)(3)(A) and the “safe harbor” regulations regarding discounts or other reductions in price set forth in 42
C.F.R. § 1001.952(h). In this regard, Buyer may have an obligation to accurately report, under any state or federal program
which provides cost or charge based reimbursement for the products or services covered by the Agreement, or as otherwise requested
or required by any governmental agency, the net cost actually paid by the Buyer and/or each Pharmacy.
