(“Parent”), and Royal Empress, Inc., a Delaware corporation and a wholly owned subsidiary of Parent. The following are the final voting results for this proposal:

Proposal 2

The Company’s stockholders approved the proposal to approve, by non-binding advisory vote, certain compensation arrangements for the Company’s named executive officers in connection with the merger contemplated by the Merger Agreement. The following are the final voting results for this proposal:

Proposal 3

Because there were sufficient votes at the time of the Special Meeting to approve the proposal to adopt the Merger Agreement, the vote on the proposal to adjourn the Special Meeting, if necessary or appropriate, to solicit additional proxies was not called.

On July 1, 2014, the Company issued a press release announcing (1) that the Company’s stockholders voted to adopt the Merger Agreement and (2) that the Company has received notice of clearance of the proposed merger from the Ukrainian Antimonopoly Committee. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

Safe Harbor for Forward-Looking Statements

This Form 8-K, in particular statements regarding the proposed transaction between an affiliate of Forest Laboratories, LLC (as successor to Forest Laboratories, Inc.) and the Company, the expected timetable for completing the transaction, future financial and operating results, benefits and synergies of the transaction, future opportunities for the combined company and any other statements about Forest Laboratories, LLC or Company managements’ future expectations, beliefs, goals, plans or prospects, includes forward-looking statements that are based on certain beliefs and assumptions and reflect the current expectations of the Company, Forest Laboratories, LLC, and their respective management. Statements that are predictive in nature, that depend on or relate to future events or conditions, or that include words such as “believes,” “anticipates,” “expects,” “continues,” “predict,” “potential,” “contemplates,” “may,” “will,” “likely,” “could,” “should,” “estimates,” “intends,” “plans” and other similar expressions are forward-looking statements. All statements other than statements of historical fact are statements that could be deemed forward-looking statements. Forward-looking statements involve known and unknown risks, assumptions and uncertainties that may cause actual results in future periods to differ materially from those projected or contemplated in the forward-looking statements, and you should not place undue reliance on these statements. Some of the factors that could cause actual results to differ materially from current expectations are: the ability to consummate the proposed transaction; any conditions imposed on the parties in connection with the consummation of the proposed transaction; the occurrence of any event, change or other circumstances that could give rise to the termination of the agreement relating to the proposed transaction; the Company’s ability to maintain relationships with employees and third parties following announcement of the proposed transaction; the ability of the parties to satisfy the conditions to the closing of the proposed transaction; the risk that the proposed transaction may not be completed in the time frame expected by the parties or at all; and the risks that are described from time to time in the Company’s reports filed with the SEC, including Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, and on general industry and economic conditions.
