POSC Positron Corporation (PK)

This Amendment No. 1 to Schedule 13D is jointly filed by and on behalf of Cecil O’ Brate (the “ Reporting Person ”) to amend the Schedule 13D relating to shares of common stock, par value $0.0001 per share (the “ Common Stock ”) of Positron Corporation, a Texas corporation (the “ Issuer ”) previously filed by the Reporting Person with the Securities and Exchange Commission (as amended, the “ Schedule 13D ”). Each capitalized term used and not defined herein shall have the meaning assigned to such term in the Schedule 13D. Except as otherwise provided herein, each Item of the Schedule 13D remains unchanged.

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

On August 28, 2015, DX and certain other creditors of the Issuer filed an involuntary chapter 11 bankruptcy petition against the Issuer in the U.S. Bankruptcy Court for the Northern District of Texas, Lubbock Division (the “ Bankruptcy Court ”), in a case pending under Case No. 15-502015-rlj, and styled:  In re: Positron Corporation (the “ Bankruptcy Proceeding ”).

On April 19, 2016, certain creditors, including DX, (the “ Creditors ”) and the Issuer entered into a Terms For Agreed Structured Dismissal (“ Structured Dismissal Agreement ”) providing for the dismissal of the Bankruptcy Proceeding. On May 2, 2016, the creditors and the Issuer filed a Joint Motion to Approve Agreed Structured Dismissal Pursuant to Bankruptcy Rule 9019 (the “ Joint Motion ”). The Joint Motion has not been approved by the Bankruptcy Court, and certain creditors have filed objections to the Joint Motion. Such approval is the subject of the hearing to be held before the Bankruptcy Court on Wednesday, June 22, 2016. Certain terms of the Structured Dismissal Agreement are outlined below:

Once the order approving the Joint Motion is final and non-appealable (the “ Order ”), the Issuer will purchase any and all shares of Common Stock owned by the Reporting Person (the “ Shares ”) for the total consideration of $100,000 pursuant to a promissory note executed by the Issuer and payable to the Reporting Person (the “ Settlement Note ”). The Settlement Note will be payable at 4.5% interest in 12 monthly installments of $8,537.85 each. The Settlement Note will be secured by the Shares. Furthermore, within 10 days of the Order becoming final and non-appeal, the Issuer will convey either (i) all of the assets of Manhattan or (ii) the membership interest of Manhattan to a company and/or entity designed by DX. Upon such transaction, the Note, along with all related guarantees, security interest, and rights DX acquired from Los Alamos, will be fully extinguished, deemed paid in full, and discharged. In addition, DX may employ a consulting firm of its choice to conduct due diligence concerning the operations of the Manhattan facility located in Lubbock, Texas. In exchange for the opportunity to conduct such due diligence, DX or the Reporting Person will advance to the Issuer and Los Alamos certain funds. Upon completion of all terms included in the Structured Dismissal Agreement, the Creditors and the Issuer will prepare and file a Joint Motion to Dismiss the Bankruptcy Proceeding. Should the Bankruptcy Court determine the Issuer has failed to comply with the terms of the Structured Dismissal Agreement or if the Bankruptcy Court should fail to approve the Structured Dismissal Agreement, it must file a voluntary bankruptcy petition. In such case, it is the intention of DX to exercise the rights of a creditor in bankruptcy.

The foregoing is qualified in its entirety by reference to the Structured Dismissal Agreement and the Joint Motion, each of which is attached hereto as Exhibit 99.3 and Exhibit 99.4, respectively, and incorporated by reference herein.
