It is currently anticipated that any purchases of Common Stock by Mr. Karp upon exercise of the Options referred to in Item 5 of this Statement will be paid for with Mr. Karp's personal funds. Item 4. Purpose of Transaction. On March 6, 2002, Mr. Karp and Bear, Stearns & Co. Inc. ("Bear Stearns") entered into a sales plan (such sales plan, as amended as of April 12, 2002, the "Sales Plan") representing Mr. Karp's adoption of a written plan for trading securities that complies with the requirements of Rule 10b5-1(c)(1) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Pursuant to the Sales Plan, Bear Stearns shall exercise Options (which are Inducement Options as defined in Item 6 of this Statement) to purchase a total of 200,000 shares of Common Stock on the first business day of each calendar month during the term of the Sales Plan which shall immediately succeed the trading day on the New York Stock Exchange on which the closing sale price of the Common Stock shall be at least $30.00 per share (except that with respect to the first calendar month during the term of the Sales Plan such business day shall not be earlier than March 6, 2002) and, in addition, on one occasion during the second or third month during each three-month period covered by a Form 144, on a business day which shall immediately succeed a trading day on the New York Stock Exchange on which the closing sale price of the Common Stock shall be at least $30.00 per share (except that with respect to the first three-month period during the term of the Sales Plan such business day shall not be earlier than March 6, 2002), certain designated registered representatives of Bear Stearns may exercise discretion to estimate and exercise Options to purchase such additional number of shares of Common Stock which, net of the amount of Common Stock remaining after Common Stock is 3 of 16 withheld by the Company to pay required Federal, state and local withholding taxes due with respect to such Option exercise, together with all shares of Common Stock sold or to be sold by Bear Stearns during such three-month period, shall equal the maximum number of shares of Common Stock which may be sold by Mr. Karp during such three-month period pursuant to Rule 144 hereinafter referred to; provided, however, that Bear Stearns shall not so exercise Options if there are 250,000 or more shares of Common Stock in the Plan Account (as defined in the Sales Plan) which have not been sold by Bear Stearns pursuant to the Sales Plan; provided, further, however, that Bear Stearns shall not exercise Options to purchase more than 1,200,000 shares of Common Stock during the term of the Sales Plan and, during the term of the Sales Plan, one or more exercise of Options may be reduced so as not to exceed such limit. Thereafter, to the extent shares of Common Stock are available from the exercise of such Options, Bear Stearns shall sell, as soon as reasonably practicable but with time and price discretion, the net amount of Common Stock remaining after Common Stock is withheld by the Company to pay required Federal, state and local withholding taxes due with respect to such Option exercise (the "Monthly Sale Amount") commencing on the following business day and terminating on the business day on which all shares are sold at a gross price before deduction of commissions or mark-down of at least $30.00 per share (the "Minimum Sale Price"). Pursuant to the Sales Plan, the Company shall notify Bear Stearns not later than the opening of trading on the New York Stock Exchange on the trading day immediately succeeding the date of exercise of the number of shares of Common Stock to be withheld by the Company to pay required Federal, state and local withholding taxes due with respect to such Option exercise. Subject to the Minimum Sale Price and the other applicable provisions of the Sales Plan, Bear Stearns shall sell the Monthly Sale Amount under ordinary principles of best execution. 4 of 16 Bear Stearns agreed to conduct all sales pursuant to the Sales Plan in accordance with the manner of sale requirement of Rule 144 under the Securities Act of 1933, as amended (the "Securities Act"), and in no event shall Bear Stearns effect any sale if such sale would exceed the then-applicable volume limitation under Rule 144, assuming that the sales to be made by Bear Stearns under the Sales Plan are the only sales subject to such limitation, unless directed by Mr. Karp pursuant to a registration statement with respect to such sales in effect under the Securities Act. If not earlier terminated in accordance with the terms thereof, the Sales Plan will terminate on March 31, 2003. The Sales Plan is filed as Exhibit C to this Statement and the amendment to the Sales Plan is filed as Exhibit D to this Statement. Except as set forth above, Mr. Karp has no plans or proposals which relate to or would result in any of the matters set forth subparagraphs (a) - (j) of Item 4 of Schedule 13D. Item 5.

Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer. 10 of 16 Effective as of September 17, 1997, the Company amended and restated Harvey L. Karp's then existing agreement (as amended and restated, the "Karp Employment Agreement"). The Karp Employment Agreement has a three-year rolling term which is automatically extended so that the unexpired term on any date is always three years, unless either party gives written notice of his or its intention not to extend the term. The Karp Employment Agreement provides for Mr. Karp to serve as Chairman of the Board of Directors of the Company. Under the terms of the Karp Employment Agreement, Mr. Karp is to receive (i) an annual base salary of $606,373 (to be adjusted upward annually at a rate commensurate with increases granted to other key executives), and (ii) a discretionary cash incentive bonus consistent with the executive bonus program which the Company establishes for other key executives. In addition, Mr. Karp is to receive reimbursement for reasonable business and travel expenses incurred in the performance of his duties and will participate in all bonus, incentive, stock option, pension, disability and health plans and programs and all fringe benefit plans maintained by the Company in which senior executives participate. Under the terms of the Karp Employment Agreement, Mr. Karp's employment may be terminated by the Company without Cause (as defined in the Karp Employment Agreement) or by Mr. Karp for Good Reason (as defined in the Karp Employment Agreement) upon appropriate written notice. In either such event, Mr. Karp will continue to receive his then-current base salary as if his employment had continued for the reminder of the then current three-year term and an annual bonus for the remainder of the then current three-year term equal to the average bonus for the three calendar years immediately preceding the written notice of termination. In addition, all outstanding unvested Company stock options then held by Mr. Karp will immediately vest and become exercisable and Mr. Karp will continue to participate in the 11 of 16 Company's health plans and programs at the Company's expense for the remainder of such three-year term. Mr. Karp may resign voluntarily without Good Reason upon appropriate written notice to the Company. In such event, Mr. Karp will be entitled to receive any accrued but unpaid base salary and, at the Company's discretion, a bonus for the calendar year in which his resignation without Good Reason occurs. The Company may terminate Mr. Karp's employment for Cause (as defined in the Karp Employment Agreement) upon appropriate written notice. In such event, Mr. Karp will forfeit all existing Company stock options, but such options shall remain exercisable for the 30-day period following Mr. Karp's receipt of the written notice. Mr. Karp may terminate his employment for any reason within six months following a Change in Control (as defined in the Karp Employment Agreement). In such event, the Company will pay Mr. Karp a lump sum amount equal to (i) three times his then current base salary, and (ii) three times his average annual bonus for the three calendar years immediately preceding the date of termination. In addition, all outstanding unvested options then held by Mr. Karp shall become immediately exercisable. In the event that any Payment (as defined in the Karp Employment Agreement) would be subject to the excise tax imposed by the "Golden Parachute" regulations, Mr. Karp would be entitled to a gross-up payment from the Company to cover such taxes. The Karp Employment Agreement is filed as Exhibit A to this Statement. Pursuant to an Option Agreement, dated December 4, 1991, Mr. Karp was granted an option (the "Inducement Option") to acquire 2,000,000 shares of Common Stock at an exercise price of $2.0625 per share (as adjusted for subsequent stock splits). The Inducement Option is exercisable until one year after termination of Mr. Karp's employment with the Company under the Karp Employment Agreement, unless Mr. Karp's employment is terminated for Cause (as 12 of 16 defined in the Karp Employment Agreement), in which case the Inducement Option shall only remain exercisable for a period of 30 days following Mr. Karp's receipt of written notice from the Company specifying the basis for Cause. The Inducement Option is filed as Exhibit B to this Statement. Pursuant to an Option Agreement, dated March 3, 1992, Mr. Karp was granted an option (the "Subsequent Option") to acquire 1,600,000 shares of Common Stock at an exercise price of $2.0625 per share (as adjusted for subsequent stock splits). The Subsequent Option was granted to Mr. Karp in addition to the Inducement Option granted to Mr. Karp pursuant to the Karp Employment Agreement. The Subsequent Option is exercisable until one year after termination of Mr. Karp's employment with the Company under the Karp Employment Agreement, unless Mr. Karp's employment is terminated for Cause (as defined in the Karp Employment Agreement), in which case the Subsequent Option shall only remain exercisable for a period of 30 days following Mr. Karp's receipt of written notice from the Company specifying the basis for Cause. The Subsequent Option is filed as Exhibit B to this Statement. Item 7. Material to be Filed as Exhibits. The following are filed herewith as Exhibits to this Statement: A.
