On October 25, 2019, ATRM distributed its interest in LSVM to Digirad, resulting in LSVM becoming a wholly owned direct subsidiary of Digirad.

Mr. Eberwein disclaimed beneficial ownership of ATRM Preferred Stock, except to the extent of his pecuniary interest therein.

The Private Placement was made pursuant to the terms of a Stock Purchase Agreement, dated as of September 10, 2019 (the “SPA”). The shares of Company Preferred Stock sold in the Private Placement have not been registered under the Securities Act of 1933, as amended (the “Act”), and may not be resold absent registration under, or exemption from registration under, the Act.

Digirad agreed to use commercially reasonable efforts to have the registration statement declared effective by the SEC as soon as possible following the filing thereof.

In March 2020, Mr. Eberwein, sole manager of LSV Co-Invest I and LSVM, provided the Company Letter of Support for the LSVM Note, the January Note, and the June Note indicating that the applicable holder of such notes will take no adverse action against ATRM for failure to pay the principal due on the applicable note by the maturity date and intends to work with the Company and ATRM to assure our financial success. Subordination Agreement LSVM and LSV Co-Invest I are party to subordination agreements with ATRM and Gerber pursuant to which LSVM and LSV Co-Invest I agreed to subordinate the obligations of ATRM under their unsecured promissory notes to the obligations of the borrowers to Gerber. Acquisition of LSVM On April 1, 2019, ATRM entered into a Membership Interest Purchase Agreement (the “LSVM Purchase Agreement”) with LSVM and Mr. Eberwein. Pursuant to the terms of the LSVM Purchase Agreement, Mr. Eberwein sold all of the issued and outstanding membership interests of LSVM to ATRM (the “LSVM Acquisition”) for a purchase price of $100.00, subject to a working capital adjustment provision. The LSVM Acquisition closed simultaneously with the execution and delivery of the LSVM Purchase Agreement, and was deemed effective as of January 1, 2019 for accounting purposes, as a result of which LSVM became a wholly owned subsidiary of ATRM. Pursuant to the LSVM Purchase Agreement, the current assets as well as the $0.3 million promissory note issued by ATRM and current liabilities existing prior to January 1, 2019 remain with Mr. Eberwein. Cash contributions made by Mr. Eberwein subsequent to the ATRM Acquisition also exist as a payment due to Mr. Eberwein by ATRM. The LSVM Purchase Agreement contains representations, warranties, covenants and indemnification provisions customary for transactions of this type. LSVM was acquired by the Company as part of the ATRM Acquisition. Financial Assistance On May 1, 2019, the special committee of the Company’s board of directors (the “Special Committee”) approved financial assistance by the Company to ATRM, in the form of advances or cash payments on behalf of ATRM, in order assist ATRM in becoming current with its financial statements and filings with the SEC. Under the terms of this approval, the Company was authorized to advance or spend up to an aggregate maximum amount of $0.4 million, with subsequent increments of $0.01 million subject to further approval by a designated member of the Special Committee. On July 30, 2019, the Special Committee increased the amount of financial assistance that the Company is authorized to provide to $0.8 million.

Joint Venture On December 14, 2018, Digirad and ATRM, entered into a joint venture and formed Star Procurement, LLC (“Star Procurement”), with Digirad and ATRM each holding a 50% interest.

In accordance with the terms of the Star Procurement Limited Liability Company Agreement, Digirad made a $1.0 million capital contribution to the joint venture, which was made in January 2019.
