	Options exercisable, end of period			567,885		$	4	$	3.11

	During the second quarter of fiscal 2014, there were options to purchase 60,000 shares of Common Stock granted to the Company’s independent directors, which vest pro-ratably on a quarterly basis over the next year of service. Each independent director receives an option to purchase 10,000 shares of the Company’s Common Stock each year in which he or she is elected, appointed or continues to serve as a director pursuant to the Amended and Restated 2005 Non-Employee Directors’ Stock Option Plan, as amended. These options also vest upon a change of control event. The Company recorded $13,000 of compensation expense for the three months ended January 31, 2014 for these options. The Company recorded $29,000 and $71,000 of compensation expense for the three and six months ended January 31, 2014, respectively, for previously granted director options.

	During the second quarter of fiscal 2014, there were options to purchase 57,500 shares of Common Stock granted to the officers and certain employees of the Company. These options were granted in conjunction with the Company’s annual review of compensation as of August 1, 2013 and vest on a quarterly basis over the next four years of service. The Company recorded $3,000 of compensation expense for the three months ended January 31, 2014 for these options. The Company recorded $163,000 and $228,000 of compensation expense for three and six months ended January 31, 2014, respectively for previously granted officer and employee options. As a result of the King of Prussia facility closure, $101,000 of this compensation expense is included in exit costs for the three and six months ended January 31, 2014.

	The Company expects to issue new shares as options are exercised. As of January 31, 2014, the future compensation cost expected to be recognized for currently outstanding stock options is approximately $211,000 for the remainder of fiscal 2014, $324,000 in fiscal 2015, $238,000 in fiscal 2016, $119,000 in fiscal 2017 and $17,000 in fiscal 2018.

	The fair value of all options granted during the second quarter of fiscal 2014 was determined at the date of the grant using the Black-Scholes option-pricing model and the following assumptions:

	Expected average risk-free interest rate	2.90%
	Expected average life (in years)	10
	Expected volatility	68.60%
	Expected dividend yield	0.00%

	The expected average risk-free rate is based on the 10-year U.S. treasury yield curve in December 2013. The expected average life represents the period of time that the options granted are expected to be outstanding giving consideration to the vesting schedules, historical exercises and forfeiture patterns. Expected volatility is based on historical volatilities of the Company’s Common Stock. The expected dividend yield is based on historical information and management’s plan.

	The fair value of the in-the-money stock options outstanding was $698,000 and $2.5 million at January 31, 2014 and 2013, respectively. The fair value of in-the-money exercisable stock options was $384,000 and $830,000 at January 31, 2014 and 2013, respectively.

	Restricted Stock Plans

	Under the Company’s Second Amended and Restated Synergetics USA, Inc. 2001 Stock Plan (“2001 Plan”), the Company’s Common Stock may be granted at no cost to certain employees and consultants of the Company. Certain plan participants are entitled to cash dividends and voting rights for their respective shares. Restrictions limit the sale or transfer of these shares during a vesting period whereby the restrictions lapse either pro-ratably over a three-year to five-year period or at the end of the third, fourth or fifth year. These shares also vest upon a change of control event. Upon issuance of stock under the 2001 Plan, unearned compensation equivalent to the market value at the date of the grant is charged to stockholders’ equity and subsequently amortized to expense over the applicable restriction period. As of January 31, 2014, there was approximately $744,000 of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the 2001 Plan. The cost is expected to be recognized over a weighted average period of four years which is generally the vesting period. The Company recorded $199,000 and $262,000 of compensation expense for three and six months ended January 31, 2014, respectively. As a result of the King of Prussia facility closure, $100,000 of this compensation expense is included in exit costs for the three and six months ended January 31, 2014. The following table provides information about restricted stock grants during the six months ended January 31, 2014:

			Number of			Weighted Average Grant Date Fair Value

Fair Value Information	'
	Note 7. Fair Value Information

	Fair value is an exit price that represents the amount that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants.

	The Company does not have any financial assets which are required to be measured at fair value on a recurring basis. Non-financial assets such as goodwill, intangible assets and property, plant and equipment are measured at fair value when there is an indicator of impairment or at least annually and recorded at fair value only when impairment is recognized. No impairment indicators existed as of January 31, 2014.

	The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value because of the short maturity of these items.

	The Company has entered into change of control agreements with each of its President and Chief Executive Officer, Chief Financial Officer, Vice President of Domestic Sales and Vice President of Marketing and Technology. The change of control agreements with its executive officers provide that if employment is terminated within one year for cause or disability following a change in control (as each term is defined in the change in control agreements), as a result of the officer’s death, or by the officer other than as an involuntary termination (as defined in the change in control agreements), the Company shall pay the officer all compensation earned or accrued through his or her employment termination date, including (i) base salary; (ii) reimbursement for reasonable and necessary expenses; (iii) vacation pay; (iv) bonuses and incentive compensation; and (v) all other amounts to which they are entitled under any compensation or benefit plan of the Company (“Standard Compensation Due”).

	If the officer’s employment is terminated within one year following a change of control without cause and for any reason other than death or disability, including an involuntary termination, and provided the officer enters into a separation agreement within 30 days of his or her employment termination, he or she shall receive the following: (i) all Standard Compensation Due and any amount payable as of the termination date under the Company’s objectives-based incentive plan, the sum of which shall be paid in a lump sum immediately upon such termination; and (ii) an amount equal to one times his or her annual base salary at the rate in effect immediately prior to the change in control, to be paid in 12 equal monthly installments beginning in the month following his or her employment termination. Furthermore, all of the officer’s awards of shares or options shall immediately vest and be exercisable for one year after the date of his or her employment termination.

	Various claims, incidental to the ordinary course of business, are pending against the Company. In the opinion of management, after consultation with legal counsel, resolution of these matters is not expected to have a material effect on the accompanying financial statements.

	The Company is subject to regulatory requirements throughout the world. In the normal course of business, regulatory agencies may require companies in the medical industry to change their products or operating procedures, which could affect the Company. The Company regularly incurs expenses to comply with these regulations and may be required to incur additional expenses. Management is not able to estimate any additional expenditures outside the normal course of operations which will be incurred by the Company in future periods in order to comply with these regulations.

	Note 11. Recent Accounting Pronouncements

	In March 2013, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update requiring an entity to release into net income the entire amount of a cumulative translation adjustment related to its investment in a foreign entity when as a parent it either sells a part or all of its investment in the foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets within the foreign entity. This accounting standard update will be effective for the Company beginning in the first quarter of fiscal 2015. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

	In July 2013, the FASB issued an accounting standard update that provides explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. Under the new standard update, unrecognized tax benefit, or a portion of an unrecognized tax benefit, is to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward or a tax credit carryforward. This accounting standard update will be effective for the Company beginning in the first quarter fiscal 2015 and applied prospectively with early adoption permitted. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

	The Company has reviewed all other recently issued, but not yet effective, accounting pronouncements and does not believe any such pronouncements will have a material impact on its financial statements.

[1]	Net sales to OEM customers represent sales of electrosurgery generators, disposable bipolar forceps and related accessories and royalties from Codman, multi-channel ablation generators, disposable ultrasonic tips and related accessories to Stryker and sales of certain disposable products to Mobius Therapeutics LLC. In addition, deferred revenues of $322,000 from the 2010 settlement with Alcon, Inc. (the "2010 Alcon settlement") are included in this category for the three and six months ended January 31, 2014 and 2013, respectively. However, as cash from the 2010 Alcon settlement has already been collected, it will not impact the Company's future liquidity.
[2]	Net sales from Other represent direct neurosurgery revenues and other miscellaneous revenues.
