“Closing of the Merger

American Stock Transfer & Trust Co., LLC, the depositary for the Offer, has advised WC SACD One, Inc. that the final results of Purchaser’s cash tender offer to purchase all of the issued and outstanding Shares of the Company for $3.68 per share in cash, which expired at 5:00 P.M., New York City time, on Friday, January 4, 2019 were as follows: as of the expiration of the Offer, a total of 13,443,400 shares of Common Stock of the Company were validly tendered and not validly withdrawn from the Offer (including 8,012 shares that were validly tendered pursuant to the notice of guaranteed delivery procedures), of which 10,635,230 shares were tendered by stockholders who are not rollover participants or directors or executive officers who are not rollover participants.

On January 11, 2019, immediately prior to the Effective Time of the Merger, the Notes automatically converted in accordance with their terms into an aggregate of 15,005,435 shares of Common Stock, of which (a) 13,240,089 were issued to Parent, (b) 1,324,009 were issued to Loeb Holding Corporation and (c) 441,337 were issued to David McGough. In addition, the transactions contemplated by the Contribution and Assignment Agreements were consummated in accordance with their terms, with the Rollover Shares consisting of (i) 8,803,640 shares held by Loeb Holding Corporation, (ii) 922,154 shares held by Michael Stanfield, (iii) 577,846 shares held by Stanfield Family Investments LLC), and (iv) 800,000 shares held by David McGough. Immediately following the contribution by the Rollover Holders of the Rollover Shares to WC SACD and prior to the consummation of the Merger, WC SACD contributed and assigned the Rollover Shares to Parent.

Subsequently, on January 11, 2019, Parent completed its acquisition of the Company pursuant to the terms of the Merger Agreement, wherein Purchaser merged with and into the Company in accordance with Section 251(h) of the DGCL, with the Company surviving as an indirect wholly-owned subsidiary of Parent. At the Effective Time, each issued and outstanding Share not tendered into the Offer, other than Shares held by stockholders who have perfected their appraisal rights under Delaware law, Shares held in the treasury of the Company or owned, directly or indirectly, by Parent or Purchaser immediately prior to the Effective Time (including the Rollover Shares), were automatically cancelled and converted into the right to receive $3.68 in cash (without interest and subject to deduction for any applicable withholding tax), which is the same price that was paid in the Offer. A copy of the press release detailing the consummation of the Merger, and all information contained therein, is incorporated herein by reference to Exhibit (a)(5)(E) hereto.

Immediately following the effectiveness of the Merger, the Company notified the Nasdaq Global Select Market (“ Nasdaq ”) of the completion of the Merger and the Company’s intent to remove its Common Stock from listing on the Nasdaq. On January 11, 2019, Nasdaq filed with the SEC a Form 25 to delist and deregister the Common Stock under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”). Trading of the Common Stock on the Nasdaq was suspended as of approximately 9:00 a.m. New York City time on January 14, 2019. In addition, the Company intends to file with the SEC a certification and notice of termination on Form 15 with respect to the Common Stock, requesting that the Common Stock be deregistered under the Exchange Act, and that the reporting obligations of the Company with respect to the Common Stock under Sections 13(a) and 15(d) of the Exchange Act be suspended.

Closing of the iSubscribed Merger

Additionally, pursuant to the Binding Term Sheet and subsequent definitive documentation that was executed and delivered by the parties thereto, the merger of iSubscribed with and into WC SACD Holdings Merger Sub, Inc. was completed on January 11, 2019. iSubscribed survived the merger and became a wholly-owned subsidiary of WC SACD Holdings, Inc.”
