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 (the “Closing Date”). In connection with the closing of the Merger, each share of iSatori common stock outstanding on the Closing Date became exchangeable for 0.1732 shares of the Company's common stock (the “Exchange Ratio”). In the event any iSatori shareholder would otherwise be entitled to a fractional share of the Company's common stock, the Company agreed to pay the value of those fractional interests in cash. The Company has issued a total of 2,315,644 shares of common stock and paid a total of $239 for remaining fractional interests to former iSatori shareholders in connection with the Merger. 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, 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, on or before December 31, 2015, almost 600,000 shares of the Company’s common stock, otherwise issuable to the two largest shareholders of iSatori, and secured a right of first refusal to purchase approximately 460,000 shares of the Company’s common stock issuable to a certain iSatori shareholder in the connection with the Merger. After careful consideration of many factors, including available cash resources, the Company’s Board of Directors elected not to exercise the purchase option prior to its expiration. The right of first refusal, however, remains outstanding. 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 was deemed satisfied in full in connection with the Closing Date of the Merger and was included as an element of the total purchase price, which also included the assumption of outstanding debt of approximately $1.1 million and the issuance of approximately 2.3 million shares of Company common stock. In connection with the Merger, the Company also converted all issued and outstanding options and warrants of iSatori into options and warrants of FitLife in an amount equal to the number of iSatori options and warrants issued and outstanding multiplied by the Exchange Ratio, at an exercise equal to the original exercise price divided by the Exchange Ratio. The treasury stock net equivalent of all issued and outstanding options and warrants were factored into the calculation of the final Exchange Ratio, the vast majority of which were and remain significantly out of the money. At closing, in connection with adjustment provisions outlined in the Merger Agreement, iSatori established 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 from 0.3000 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 April 12, 2016, 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.

Recent Developments

iSatori Merger. 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 (the “Closing Date”).

In connection with the closing of the Merger, each share of iSatori common stock outstanding on the Closing Date became exchangeable for 0.1732 shares of the Company's common stock (the “Exchange Ratio”). In the event any iSatori shareholder would otherwise be entitled to a fractional share of the Company's common stock, the Company agreed to pay the value of those fractional interests in cash. The Company has issued a total of 2,315,644 shares of common stock and paid a total of $239 for remaining fractional interests to former iSatori shareholders in connection with the Merger.

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, 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, on or before December 31, 2015, almost 600,000 shares of the Company’s common stock, otherwise issuable to the two largest shareholders of iSatori, and secured a right of first refusal to purchase approximately 460,000 shares of the Company’s common stock issuable to a certain iSatori shareholder in the connection with the Merger. After careful consideration of many factors, including available cash resources, the Company’s Board of Directors elected not to exercise the purchase option prior to its expiration. The right of first refusal, however, remains outstanding.

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 was deemed satisfied in full in connection with the Closing Date of the Merger and was included as an element of the total purchase price, which also included the assumption of outstanding debt of approximately $1.1 million and the issuance of approximately 2.3 million shares of Company common stock. In connection with the Merger, the Company also converted all issued and outstanding options and warrants of iSatori into options and warrants of FitLife in an amount equal to the number of iSatori options and warrants issued and outstanding multiplied by the Exchange Ratio, at an exercise equal to the original exercise price divided by the Exchange Ratio. The treasury stock net equivalent of all issued and outstanding options and warrants were factored into the calculation of the final Exchange Ratio, the vast majority of which were and remain significantly out of the money.

At closing, in connection with adjustment provisions outlined in the Merger Agreement, iSatori established 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 from 0.3000 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 April 12, 2016, 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.
