WHEREAS, Seller desires to sell and Purchaser desire to purchase an aggregate of 1,250,000 shares of common stock of Pernix Therapeutics, Inc. (“PTX”) in exchange for the issuance of 250 Units (as defined in the Second Amended and Restated Limited Liability Company Agreement of Purchaser dated May 14, 2013 (the “LLC Agreement”)) to the Seller by the Purchaser;

NOW, THEREFORE, in consideration of the foregoing, and the respective representations, warranties, covenants and agreements set forth herein, the parties hereto agree as follows:

1.  Sale and Purchase of Shares.  Subject to and in accordance with the terms and conditions of this Agreement, Seller hereby sells, transfers and assigns to Purchaser, and Purchaser hereby purchases, 1,250,000 shares of PTX common stock (the “Shares”).

(h)  Seller is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated under the Securities Act, as such rule is presently in effect.

(i)  The execution and delivery by Seller of this Agreement, and the consummation by Seller of the transactions contemplated hereby, will not (a) violate or conflict with any law or governmental order applicable to Seller or by which any of his properties or assets may be bound, (b) require any filing with, or permit, consent or approval of, or the giving of any notice to, any governmental authority or (c) result in a violation or breach of, conflict with, constitute (with or without due notice or lapse of time or both) a default under (or give rise to any right of termination, cancellation, payment or acceleration or any right under) or result in the creation of any lien upon any of the properties or assets of Seller under, any contract, permit, or other obligation to which Seller is a party, or by which Seller or any of his properties or assets are bound.

(f)  Purchaser understands that, as of the Closing, the Shares have not been registered under the Securities Act, or applicable state securities laws, and Purchaser hereby agrees not to make any sale, transfer or other dispositions of the Shares unless either (i) the Shares have been registered under the Securities Act, and all applicable state securities laws, and any such registration remains in effect or (ii) registration is not required under the Securities Act or applicable state securities laws with respect to such sale, transfer or other disposition.

(g)  Purchaser is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated under the Securities Act, as such rule is presently in effect.

(j)  Purchaser is not an “investment company” as such term is used in Section 721 of the Internal Revenue Code of 1986, as amended.

6.  Valuation Adjustment.  If Purchaser sells any of the Shares and the Closing Price (as defined below) is below $3.80 on the date of the closing of such sale, then Purchaser shall promptly following such sale redeem from Seller, and Seller shall transfer to Purchaser, for no further consideration, a pro rata portion of the Issued Units Seller received under this Agreement equal to (I) (i) 100 percent, less (ii) the ratio determined by dividing the Closing Price on the date of such sale by the Closing Price on the date of this Agreement, and (II) the ratio determined by dividing the number of Shares sold by Purchaser by 1,250,000.

3

In this Section 6, “Closing Price” means the closing price per share of PTX common stock as reported on the Nasdaq Stock Market or a similar national exchange.  Exhibit B sets out a sample calculation of the number of Issued Units to be transferred and redeemed pursuant to this Section 6

Such redemption and transfer shall be pursuant to such transfer documents as are reasonably agreed between the parties, provided that such documents shall require Seller to provide customary representations and warranties as concern title to and ownership of the applicable Units, his capacity, execution and delivery of relevant documents, and enforceability of such documents against Seller.

7.  Power of Attorney for Voting of Shares.  Purchaser hereby appoints Seller as Purchaser’s true and lawful attorney and proxy to exercise the voting rights attached to the Shares in Purchaser’s name and on Purchaser’s behalf at all or any meetings of the shareholders of PTX, as Seller in his discretion deems fit, or by executing any resolution in writing by such shareholders as fully as Purchaser would be able to do if personally present, provided, however, that the rights and powers conferred upon the Seller pursuant to this Section 9 shall terminate on the date that is six months following the date of this Agreement (the “Voting Termination Date”).  Purchaser shall procure that any person to whom Purchaser sells any Shares prior to the Voting Termination Date shall issue a power of attorney substantially in the form set out in this Section 9 in favor of Seller, such power of attorney to terminate on the Voting Termination Date.

8.  Tax Issues.  The parties intend that the sale and issuance transactions contemplated by this Agreement will qualify as a “contribution of property to the partnership in exchange for an interest in the partnership” in accordance with Section 721 of the Internal Revenue Code of 1986, as amended, such that no gain or loss would be recognized to the Purchaser or the Seller in respect of such transactions.  Each party shall, except as otherwise required by applicable law, refrain from taking a position contrary to such intention in any filings made by such party with any tax authority.

9.  Miscellaneous.  This Agreement (and the documents and instruments referred to herein) constitute the entire Agreement between the parties with respect to the matters herein addressed, and supersede and cancel all prior or contemporaneous agreements, representations, warranties, communications or understandings, whether oral or written.  This Agreement may not be modified or amended except by a writing duly executed and delivered by the parties.  No waiver of any provision of this Agreement shall be effective against a party unless in a writing duly executed and delivered by such party.  No waiver of any particular provision of this Agreement shall constitute a waiver of any other provision hereof.  No waiver of any provision of this Agreement in respect of a particular event or circumstance shall constitute a waiver of the same provision in respect of any other event or circumstance.  This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, legal representatives, executors, administrators, successors and assigns.  The invalidity or unenforceability of any provision of this Agreement shall not render invalid or unenforceable any other provision hereof.  This Agreement shall be governed by and construed in accordance with the laws of the State of Texas, without giving effect to its choice of law provisions.  This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.  Each party shall perform any further acts and sign and deliver any further documents that are reasonably necessary to carry out the provisions of this Agreement.

SAMPLE CALCULATION

If the Closing Price on the date of this Agreement is $4.05, the Closing Price on the date of the relevant sale is $3.60, and the number of Shares sold in the relevant sale is 1,000,000, the calculations under Section 6 are as follows:

●   Number of Issued Units: 250

●   The ratio determined by dividing the Closing Price on the date of such sale by the Closing Price on the date of this Agreement: $3.60/$4.05 = 88.889 percent

●   The ratio determined by dividing the number of Shares sold by Purchaser by 1,250,000: 1,000,000/1,250,000 = 80 percent

●   Number of Issued Units to be redeemed by Purchaser from Seller: 250 * (100% – 88.889%) * 80% = 22.222 Units
