SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934 requires CRA's officers and directors, and persons who own more than 10% of CRA's common stock, to file reports of ownership and changes in ownership with the Securities and Exchange Commission. SEC regulations require officers, directors and greater-than-10% stockholders to furnish CRA with copies of all Section 16(a) forms they file. Based solely upon a review of Forms 3 and 4 and amendments thereto furnished to CRA during fiscal 1998 and Forms 5 and amendments thereto furnished to CRA with respect to fiscal 1998, or written representations that Form 5 was not required, CRA believes that all Section 16(a) filing requirements applicable to its officers, directors and greater-than-10% stockholders were fulfilled in a timely manner, with the exception of one late Form 3 filing by Dr. Salop and one late Form 3 filing by Dr. Saloner. After investigating these matters, CRA has concluded that any omissions were inadvertent, and that none of the transactions gave rise to liability under Section 16(b) of the Securities Exchange Act of 1934 for recapture of short-swing profits. ITEM 11. EXECUTIVE COMPENSATION. EXECUTIVE COMPENSATION Compensation Summary. The following table sets forth certain information concerning the compensation earned by CRA's Chief Executive Officer and other executive officers for services rendered in all capacities to CRA for the fiscal years ended November 29, 1997 and November 28, 1998. 5

The option granted to Ms. Morrison vests in four equal annual installments, the first of which vests on September 14, 1999. The option granted to Mr. Burnett vested immediately upon grant. (2) In fiscal 1998, CRA granted to employees options to purchase an aggregate of 316,500 shares of common stock under CRA's stock option plan. (3) All options were granted at fair market value as determined by the board of directors on the date of grant. (4) Amounts reported in this column represent hypothetical values that may be realized upon exercise of the options immediately prior to the expiration of their term, assuming the specified compounded rates of appreciation of the price of the common stock over the term of the options. These numbers are calculated based on rules promulgated by the Securities and Exchange Commission and do not represent CRA's estimate of future stock price growth. Actual gains, if any, on stock option exercises and common stock holdings depend on the timing of the exercise of the option and the sale of the common stock, as well as the future performance of the common stock. The rates of appreciation assumed in this table may not be achieved and the officers may never receive the amounts reflected. This table does not take into account any appreciation in the price of the common stock from the date of grant to the current date. The values shown are net of the option exercise price, but do not include deductions for taxes or other expenses associated with the exercise. Fiscal Year-End Option Values. The following table sets forth certain information concerning stock options held at November 28, 1998 by CRA's Chief Executive Officer and other executive officers. No executive officer exercised any stock options in fiscal 1998. 7

Burnett ..... 3,500 -- -- -- - ------------------------ (1) Value is based on $22.50 per share, the last sale price of the common stock on November 27, 1998, as reported on the Nasdaq National Market. On that date, the value of the common stock was less than the applicable exercise price of these options. Actual gains, if any, on exercise will depend on the value of the common stock on the date of the sale of the shares. DIRECTOR COMPENSATION CRA pays its non-employee directors an annual fee of $13,000 for their services as directors, plus $2,000 for each regular board meeting attended and $1,000 for each special board meeting attended. Directors who are also employees of CRA do not receive separate fees for their services as directors. See "Item 13. Certain Relationships and Related Transactions" for information concerning consulting fees paid by CRA to certain directors for their services as outside experts to CRA. Under CRA's 1998 Incentive and Nonqualified Stock Option Plan, each "outside director" who shall be re-elected as a director of CRA or whose term shall continue after an annual meeting of stockholders will on the date of the annual meeting receive a nonqualified option to purchase 5,000 shares of common stock at an exercise price equal to the fair market value of the common stock on that date. Each option will have a term of five years and will vest in full on the first anniversary of the date of grant. Each person who shall be first elected an outside director of CRA after the adoption of the stock option plan will receive on the date of his or her election as a director a nonqualified option to purchase 10,000 shares of common stock at an exercise price equal to the fair market value of the common stock on that date. Each option will have a term of five years and will vest in three equal annual installments, commencing on the first anniversary of the date of grant. Under the terms of the stock option plan, an "outside director" is a director who (a) is not an employee of CRA or any parent or subsidiary of CRA and (b) is not a consultant who provides economic consulting services to or in conjunction with CRA or any parent or subsidiary of CRA. Currently, the outside directors of CRA are Drs. Kaysen, Moriarty and Saloner. In accordance with the terms of CRA's stock option plan, in connection with CRA's annual meeting of stockholders in April 1998, each of Drs. Moriarty and Kaysen was granted a nonqualified option to purchase 5,000 shares of common stock at an exercise price of $18.50 per share. On his election to the board in December 1998, Dr. Saloner received a nonqualified option to purchase 10,000 shares of common stock at an exercise price of $24.75 per share. 8

STOCK RESTRICTION AGREEMENT Each person who was a stockholder of CRA before CRA's initial public offering is subject to a stock restriction agreement with CRA. The stock restriction agreement prohibits each pre-IPO stockholder from selling or otherwise transferring shares of common stock held immediately before the IPO as follows: (a) until April 24, 2000, no pre-IPO stockholder may sell any of his or her pre-IPO stock, except that he or she may sell up to 15% of his or her pre-IPO stock in a public offering; (b) from April 24, 2000 until April 24, 2003, each pre-IPO stockholder will be able to sell up to an aggregate of 50% of his or her pre-IPO stock, less any shares previously sold in public offerings; (c) from April 24, 2003 to April 24, 2005, each pre-IPO stockholder will be able to sell up to an aggregate of an additional 20% of his or her pre-IPO stock; and (d) after April 24, 2005, each pre-IPO stockholder will be able to sell, in any 12-month period, an amount equal to the greater of (1) 10% of his or her pre-IPO stock or (2) one-third of the pre-IPO stock held by him or her on April 24, 2005. Upon the death or retirement for disability of any pre-IPO stockholder in accordance with CRA's policies, the foregoing restrictions will terminate with respect to his or her pre-IPO stock. The board of directors has the discretion to waive any of the restrictions imposed by the stock restriction agreement. Under the terms of the stock restriction agreement, if any pre-IPO stockholder leaves CRA other than for death or retirement for disability in accordance with CRA's policies, CRA will have certain rights to repurchase his or her pre-IPO stock as follows: (a) until April 24, 2000, CRA may repurchase up to 85% of his or her pre-IPO stock, (b) from April 24, 2000 to April 24, 2003, CRA may repurchase up to 50% of his or her pre-IPO stock, and (c) after April 24, 2003, CRA may repurchase all of the pre-IPO stock that the pre-IPO stockholder will not have already become entitled to sell. The purchase price will be equal to 70% of the fair market value of the repurchased stock (95% in the case of pre-IPO stockholders who retire after April 24, 2003), or, if the pre-IPO stockholder competes with CRA, 40% of fair market value. The 10

11 purchase price will be payable in three equal annual installments. The stock restriction agreement will terminate on April 23, 2008 or earlier with the approval of the board of directors of CRA. PAYMENTS TO AFFILIATED PARTIES CRA has made payments to Drs. Fisher and Salop, both directors of CRA, for their services as outside experts, including for consulting services to clients and for the generation of engagements for CRA. Dr. Salop also held more than five percent of the common stock of CRA outstanding as of March 24, 1999. In fiscal 1998 and the first quarter of fiscal 1999, CRA paid Dr. Fisher an aggregate of $158,936 and $147,621, respectively. In fiscal 1998 and the first quarter of fiscal 1999, CRA paid Dr. Salop an aggregate of $676,447 and $95,700, respectively. The foregoing amounts include payments made to companies wholly owned by each of the outside experts. In fiscal 1998, CRA paid Dr. Moriarty, a director of CRA, an aggregate of $95,000 for consulting services. In addition, CRA has made certain office space and support services available to Cubex Inc., a company wholly owned by Dr. Moriarty. The portion of CRA's expenses, including rent, labor costs and insurance, allocable to the resources made available to Cubex Inc., net of reimbursements, was $73,079 and $17,263 in fiscal 1998 and the first quarter of fiscal 1999, respectively. SALE OF STOCK In August 1997, CRA sold 26,000 shares of common stock to Laurel E. Morrison, the Chief Financial Officer, Vice President, Finance and Administration, and Treasurer of CRA, at a purchase price of approximately $2.71 per share, which represented the fair market value per share at that time, as determined by CRA's board of directors. Ms. Morrison paid $24,000 at the time of purchase and the remainder in April 1998. REPURCHASE OF STOCK In May 1995, CRA repurchased 59,800 shares of common stock from each of Dr. Fisher and Alan R. Willens, a former director of CRA, in each case for a purchase price equal to the sum of (a) $33,695, payable in three equal annual installments, (b) an amount, payable in five annual installments, equal to his pro rata portion of 25% of CRA's earnings before bonuses, supplemental compensation and amortization of goodwill for each of fiscal 1995, fiscal 1996, fiscal 1997, fiscal 1998 and fiscal 1999, of which CRA had paid $78,383 as of February 19, 1999, and (c) $2,020, paid in April 1996. PAYMENTS TO LANDLORD In 1978, CRA entered into an office lease agreement with John Hancock Mutual Life Insurance Company for office space for CRA's headquarters. The lease has been amended on several occasions since that time to increase the space leased by CRA, to modify CRA's rental payments and to make other changes. Based solely on a Schedule 13G filed by John Hancock Mutual Life Insurance Company and related parties on January 22, 1999, CRA believes that on 11

12 December 31, 1998, John Hancock Advisers, Inc., an investment adviser and an indirect, wholly owned subsidiary of John Hancock Mutual Life Insurance Company, purchased 555,200 shares of CRA's common stock from persons unrelated to CRA and thereby acquired more than 5% of CRA's outstanding common stock. John Hancock Advisers, Inc. purchased the shares on behalf of various portfolios, funds and accounts for which it acts as investment adviser. In fiscal 1998 and fiscal 1999 (through March 19, 1999), CRA's payments under the lease were $1,236,072 and $437,459, respectively.
