During the fiscal year ended March 31, 2005, and currently, the audit committee of the board consists of Messrs. Marguglio, Greber and Langley.

Sonic’s board of directors has determined that Mr. Greber qualifies as an audit committee financial expert, as defined by the applicable rules of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), pursuant to, among other things, his association with The Pacific Stock Exchange in various capacities, including Chairman, Chief Executive Officer and Chief Operating Officer, and his position as Chief Executive Officer of Diagnostic Network, Inc., and in those capacities had acquired the relevant experience and expertise and has the attributes set forth in the applicable rules as being required for an audit committee financial expert.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires Sonic’s directors and executive officers, and persons who own more than 10% of a registered class of Sonic’s equity securities, to file reports of ownership on Form 3 and changes in ownership on Form 4 or 5 with the Securities and Exchange Commission. Such officers, directors and 10% shareholders are also required by Securities and Exchange Commission rules to furnish Sonic with copies of all Section 16(a) forms that they file.

To Sonic’s knowledge, based solely on review of the copies of such reports furnished to Sonic and written representations that no other reports were required, during the fiscal year ended March 31, 2005, each of the directors, executive officers and 10% shareholders complied with all Section 16(a) filing requirements during the fiscal year ended March 31, 2005.

Code of Business Conduct and Ethics

Sonic’s board of directors adopted a code of business conduct and ethics in March 2004. This code applies to all of Sonic’s employees and is posted on its web site at www.sonic.com. The code satisfies the requirements under the Sarbanes-Oxley Act of 2002, as well as Nasdaq rules applicable to issuers listed on the Nasdaq National Market. The code, among other things, addresses issues relating to conflicts of interests,

2

including internal reporting of violations and disclosures, and compliance with applicable laws, rules and regulations. The purpose of the code is to deter wrongdoing and to promote, among other things, honest and ethical conduct and to ensure to the greatest possible extent that our business is conducted in a legal and ethical manner. Any waivers of the code with respect to Sonic’s executive officers and directors may be granted only by the audit committee. Any waivers of the code with respect to the remainder of the employees may be granted by the corporate compliance officer, which is currently Sonic’s Chief Executive Officer. Any waivers of the code and any amendments to the code applicable to the Chief Executive Officer, Chief Financial Officer, principal accounting officer, controller or persons performing similar functions, will be posted on Sonic’s web site.

(1) Options vest over a period of one year at a rate of 8.333% per month.

(2) Options vest over a period of three years at a rate of 2.778% per month.

The exercise price is equal to the fair market value of Sonic’s common stock on the date of grant, as determined by reference to the closing price of Sonic’s common stock on the Nasdaq National Market. The options are subject to earlier expiration in the event of the officer’s termination of employment with Sonic. Potential realizable value is based on an assumption that the fair market value of the stock on the date of grant appreciates at the stated rate, compounded annually, from the date of grant until the end of the option terms. These values are calculated based on requirements promulgated by the Securities and Exchange Commission and do not reflect Sonic’s estimate of future stock price appreciation. All of the options in the above table were granted under Sonic’s stock option plans.

The following table sets forth information regarding the number and value of options exercised during the fiscal year ended March 31, 2005 and of unexercised options held by the named executive officers on March 31, 2005. Value of in-the-money options is considered to be the difference between the exercise price and the closing price of $15.05 per share of the common stock as quoted on the Nasdaq National Market on March 31, 2005.

Sonic did not make any awards during the fiscal year ended March 31, 2005 to any of the executive officers named in the Summary Compensation Table under any long-term incentive plan providing compensation intended to serve as incentive for performance to occur over a period longer than one fiscal year, excluding the stock options set forth above.

Compensation Committee Interlocks and Insider Participation

The audit committee, functioning as the compensation committee, determined executive compensation for fiscal 2005. No member of the audit committee served as an officer or employee of Sonic or any of its

A description of the material features of Sonic’s 2004 Stock Incentive Plan (the “2004 Incentive Plan”), which was not approved by Sonic’s shareholders, is set forth below. In March 2005, the board of directors adopted the 2005 Stock Incentive Plan (Non-U.S. Employees) (“Non-U.S. Plan”) for the grant of stock options to non-U.S. employees. The terms and the purposes of the Non-U.S. Plan and the 2004 Incentive Plan are substantially similar. Awards under the Non-U.S. Plan and the 2004 Incentive Plan are granted only to employees of Sonic as a material inducement to the employee’s entering into service with Sonic. The board of directors reserved 750,000 shares of common stock for issuance under the Non-U.S. Plan that were previously reserved under the 2004 Incentive Plan. As of March 31, 2005, no options have been granted pursuant to the Non-U.S. Plan. The Non-U.S. Plan was not approved by Sonic’s shareholders. The Non-U.S. Plan will continue in effect until 2015.

2004 Stock Incentive Plan

Sonic’s board of directors adopted the 2004 Incentive Plan in March 2004. A maximum of 1,250,000 shares of common stock is currently available for issuance under the 2004 Incentive Plan. The board of directors, or a committee designated by the board of directors, administers the 2004 Incentive Plan. The administrator has the sole discretion to interpret any provision of the 2004 Incentive Plan, and to determine the terms and conditions of awards of non-qualified stock options, restricted stock and other awards granted under the 2004 Incentive Plan. Awards may be granted under the 2004 Incentive Plan only to employees of Sonic (i) who have not previously been an employee or director of Sonic, or (ii) following a bona fide period of non-employment or non-service to Sonic. Further, awards under the 2004 Incentive Plan are granted as a material inducement to the employee’s entering into service with Sonic. The material features of the 2004 Incentive Plan are summarized below.

Term.    The term of each award shall be stated in the applicable option agreement.

Exercise or Purchase Price.    The exercise or purchase price per share of common stock for awards shall be such price as is determined by the administrator.

Vesting.    Each award shall vest in accordance with a schedule as determined by the administrator.

Transferability.    Awards are transferable to the extent provided in the applicable option agreement.

Termination of Employment.    A participant may not exercise an award after the termination of the participant’s employment or director relationship with Sonic or any parent or subsidiary of Sonic, except to the extent specified in the applicable award agreement. Where the award agreement permits the exercise of the award following termination of the participant’s employment or other service relationship with Sonic or any parent or subsidiary of Sonic, the award shall terminate to the extent not exercised on the last day of the specified period or the last day of the term of the award, whichever occurs first.

Acquisition of Sonic.    If Sonic is acquired whether by sale, transfer of assets, merger or similar transaction, any award not assumed or replaced shall automatically become fully vested and exercisable and be released from any repurchase or forfeiture rights immediately prior to the specified effective date of such sale, transfer of assets, merger or similar transaction.

Amendment and Termination of the Plan.    The 2004 Incentive Plan will continue in effect until 2014. The board may amend the 2004 Incentive Plan at any time or from time to time or may suspend or terminate it, without approval of the shareholders, except as required by law. However, no action by the board of directors or shareholders may alter or impair any award previously granted under the 2004 Incentive Plan. In connection with the board’s adoption of the Non-U.S. Plan in March 2005, the board reduced the number of shares reserved for issuance under the 2004 Incentive Plan from 2,000,000 shares to 1,250,000 shares. No option may be granted during any suspension of or after termination of the 2004 Incentive Plan.
