On September 30, 2015, the Company consummated the Merger contemplated by the Agreement and Plan of Merger, dated May 18, 2015 (the “Merger Agreement”), among the Company, ISFL Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of the Company (“Merger Sub”), and iSatori, pursuant to which iSatori merged with and into Merger Sub, with iSatori surviving as a wholly-owned subsidiary of the Company. The Merger was approved by iSatori shareholders at a special meeting held on September 29, 2015 and became effective on October 1, 2015. In connection with the closing of the Merger, each holder of iSatori common stock has the right to receive 0.1732 shares of the Company's common stock for every share of iSatori common stock held on the Closing Date (the “Exchange Ratio”). The Company expects to issue approximately 2.3 million shares of common stock to iSatori shareholders. In the event any iSatori shareholder would otherwise be entitled to a fractional share of the Company's common stock, the Company will pay the value of those fractional interests in cash. Each outstanding stock option, warrant, and restricted stock unit measured in relation to, or settleable in, shares of iSatori common stock, as well as each award of restricted stock relating to shares of iSatori common stock, whether vested or unvested, was assumed by the Company and converted automatically into an option, warrant, restricted stock unit or restricted stock award, as the case may be, denominated in shares of FitLife common stock based on the Exchange Ratio. Pursuant to the terms and conditions of the Merger Agreement, the Company increased the size of its Board of Directors (the “Board”) from five to seven members, appointed Stephen Adele, the former Chief Executive Officer of iSatori, to serve on the Board, and appointed two independent directors, Messrs. Seth Yakatan and Todd Ordal, each of whom were designated by iSatori, to the Board. Concurrently with these appointments, Dr. Fadi Aramouni resigned from the Board. In addition to the foregoing, the Company secured an option to purchase almost 600,000 shares of the Company’s common stock issuable to the two largest shareholders in iSatori in connection with the Merger. Under the terms of the option, the Company may repurchase all or any portion thereof the applicable shares in its sole discretion any time prior to December 31, 2015. The Company also secured a right of first refusal to purchase more than additional 460,988 shares of the Company’s common stock issuable to a certain iSatori shareholder in the connection with the Merger. On September 11, 2015, the Company loaned iSatori $750,000 pursuant to a Demand Promissory Note ("Note"), due and payable on demand after October 15, 2015 in the event the Merger was not consummated on or before such date. The proceeds from the Note were to be used by iSatori for the payment, in the ordinary course of business, of payroll and accounts payable of iSatori pending consummation of the Merger. The Note is expected to be deemed satisfied in full in connection with the effective date of the Merger and included as an element of the total purchase price, which also included the assumption of outstanding debt and the issuance of shares of Company common stock. At closing, in connection with adjustment provisions outlined in the Merger Agreement, iSatori agreed to establish certain reserves and write-offs totaling approximately $1.8 million, which write-offs, together with the issuance of the Note and other variances of certain working capital accounts, resulted in a reduction of the Exchange Ratio under the terms of the Merger Agreement to 0.1732 shares of common stock of the Company for each share of iSatori common stock issued and outstanding. Share Repurchase Program. On June 30, 2014, the Company’s Board of Directors approved a share repurchase program, pursuant to which the Company is authorized to purchase up to $600,000 of our common stock per annum, subject to maximum repurchases of $50,000 per month (the “Repurchase Program”). Additional purchases under the Repurchase Program may be made from time to time at the discretion of management as market conditions warrant and subject to certain regulatory restrictions and other considerations. As of November 10, 2015, the Company had repurchased an aggregate total of 206,187 shares of our common stock under the Repurchase Program at an average purchase price of $1.93 per share.
