Letters of Credit The Company has an aggregate $10 million sub-limit for standby letters of credit in conjunction with the Facility. As of April 30, 2012 and 2011, the Company has outstanding standby letters of credit of $2.9 million in connection with office leases. Employment Agreements As of April 30, 2012, the Company has employment agreements with certain of its executive officers, that provide certain benefits if these executives are terminated or resign under certain limited circumstances. The maximum amount payable under these agreements, in aggregate, is $6.1 million in the absence of a change of control and $9.0 million following a change of control and terminations or resignations which occur within 12 months from the change of control. In certain cases, executives’ outstanding options will immediately vest and remain exercisable for periods ranging from three months to their original expiration date following termination of employment. The Company has a policy of entering into offer letters of employment or letters of promotion with vice presidents which provide for an annual base salary and discretionary and incentive bonus payments. Certain key vice presidents who typically have been employed by the Company for several years may also have a standard form employment agreement. In addition, the Company has a severance policy for all of its vice presidents that provides for minimum payments based on length of service. Upon termination without cause, the Company is required to pay the greater of the amount due under the employment agreement, if any, or the severance policy. The Company also requires its vice presidents to agree in their employment letters and their employment agreement, if applicable, not to compete with the Company both during the term of their employment, and for a period of up to two years after their employment ends. For a period of two years after their employment with the Company, former vice presidents are prohibited from soliciting employees of the Company for employment outside of the Company. Litigation From time to time, the Company has been and is involved in litigation incidental to its business. The Company is currently not a party to any litigation which, if resolved adversely against the Company, would, in the opinion of management, after consultation with legal counsel, have a material adverse effect on the Company’s business, financial position or results of operations.
