Master Purchase and Sale Agreement

As disclosed in the Issuer’s Form 8-K filed on January 23, 2017, on January 21, 2017, the Issuer and its wholly-owned subsidiary, ADMA BioManufacturing, LLC, a Delaware limited liability company (“Buyer”), entered into a Master Purchase and Sale Agreement (the “Purchase Agreement”) with Biotest Pharmaceuticals Corporation, a Delaware corporation (“Seller”), and for certain limited purposes set forth in the Purchase Agreement, Biotest AG, a company organized under the laws of Germany and the ultimate parent company of Seller (“Biotest”), and Biotest US Corporation, a Delaware corporation and subsidiary of Biotest (together with Biotest, the “Biotest Guarantors”), pursuant to which Buyer has agreed to acquire (the “Acquisition”) certain assets and assume certain liabilities constituting the therapy business of Seller (the “Business”). Seller will retain its plasma business. The Business to be acquired by Buyer includes (a) a U.S. based Food and Drug Administration (FDA) licensed immune globulin manufacturing and plasma products production facility of two buildings of approximately 126,000 square feet located on approximately 15 acres of land in Boca Raton, Florida, and the associated real property, (b) all exclusive rights to FDA licensed biologics products Nabi-HB®, BIVIGAM® and the investigational product CIVACIR®, (c) in-process inventory with an agreed-upon value of at least $5 million, (d) certain other properties and assets used exclusively in the Business, and (e) certain additional assets which relate to both the Business and Seller’s plasma business the arrangement with respect to which will be documented in a transition services agreement to be mutually agreed by the parties between the signing of the Purchase Agreement and the closing of the proposed Acquisition.

Subject to the terms and conditions of the Purchase Agreement, upon the closing of the Acquisition, as part of the consideration, the Issuer has agreed to deliver to Seller an aggregate equity interest in the Issuer equal to fifty (50%), less one (1) share, of the issued and outstanding ADMA capital stock (calculated as of immediately following the closing and on a post-closing issuance basis) (the “Biotest Equity Interest”), consisting of (x) ADMA Common Stock representing twenty-five percent (25%) of the issued and outstanding Common Stock of ADMA, equal to 4,295,580 shares of Common Stock and (y) non-voting common stock equal to 8,591,160 shares of ADMA Common Stock representing the balance of the Biotest Equity Interest which is convertible into Common Stock of ADMA upon the occurrence of certain specified events.

Voting Agreement

On January 21, 2017, in connection with the execution and delivery of the Purchase Agreement, each Reporting Person entered into a Voting Agreement (each, a “Voting Agreement”) with Seller and the Company.

The Voting Agreements generally require that the Reporting Persons: (i) vote all of their shares of Common Stock in favor of the Purchase Agreement and all transactions contemplated by the Purchase Agreement; (ii) vote against any alternative transaction; (iii) not transfer their Common Stock during the term of the Voting Agreement or enter into any other voting agreement, voting trust or similar agreement with respect to any of their shares of Common Stock and (iv) not take any action that would constitute a violation of the non-solicitation provisions of the Purchase Agreement if taken by the Issuer, its representatives or affiliates, with the limitations and exceptions of such provisions of the Purchase Agreement that are applicable to the Issuer, its representatives or affiliates being similarly applicable to the Reporting Persons.

Each Voting Agreement includes a cap of 25% on the aggregate voting power represented all voting agreements signed by stockholders of the Issuer in connection with the Acquisition, taken together, if, in response to a “Superior Transaction” (as defined in the Purchase Agreement) received by the Issuer’s board of directors, the Issuer’s board of directors makes an “Adverse Recommendation Change” (as defined in the Purchase Agreement) in accordance with Section 6.8 of the Purchase Agreement and it does not terminate the Purchase Agreement. In such circumstances, the Reporting Persons voting power would be reduced pro rata along with any other stockholders who have signed voting agreements with respect to the Acquisition.

The Voting Agreements terminate upon the first to occur of (i) the closing date, (ii) the termination of the Voting Agreement by mutual consent of the parties thereto, (iii) the termination of the Purchase Agreement, (iv) September 30, 2017 and (v) any amendment, modification or waiver to the Purchase Agreement that changes the form, timing or amount of the purchase price or other consideration contemplated by the Purchase Agreement.

The foregoing description of the Voting Agreements is not complete and is qualified entirely by reference to the full text of such agreements, filed herewith.
