Board of the Company.

     (d) and (e) During the last five years, Mr. Karp has not been convicted in

future violations of, or prohibiting or mandating activities subject to, Federal

     (f) Mr. Karp is a citizen of the United States.

Item 3. Source and Amount of Funds or Other Consideration.
        -------------------------------------------------

     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 January 16, 2004, Mr. Karp and Bear, Stearns & Co. Inc. ("Bear Stearns")
entered into a sales plan (such sales plan, as amended as of February 6, 2004,
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 and Subsequent 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 January 20, 2004). In addition, on any
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 such business day shall not be earlier than
February 9, 2004), certain designated registered representatives of Bear Stearns
may exercise discretion to estimate and exercise Options to


                                       2



purchase such additional number of shares of Common Stock which, net of the
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, together with all shares of Common Stock sold by Bear
Stearns during the applicable three-month period, may equal the maximum number
of shares of Common Stock which may be sold by Mr. Karp pursuant to Rule 144(e)
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 900,000 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 business day immediately following the Option
exercise 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.

     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"), or pursuant to an effective
registration statement dated November 2, 2001 under the Securities Act (the
"Registration Statement"). In no event shall Bear Stearns effect any sale under
Rule 144 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, or sell Stock pursuant to
the Registration Statement if the number of shares to be sold exceeds that which
Mr. Karp is eligible to sell under the Registration Statement or if Bear Stearns
receives notice from the Company that the Registration Statement is no longer
effective or should no longer be used to effect sales.

     If not earlier terminated in accordance with the terms thereof, the Sales
Plan will terminate on January 31, 2005.

     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.

     Pursuant to a Separation Agreement, dated December 4, 2003, between Mr.
Karp and Karen A. Karp (the "Separation Agreement"), Mr. Karp agreed to exercise
on behalf of Karen A. Karp options to purchase 200,000 shares of Common Stock,
sell the shares of Common Stock so acquired and transfer to Karen A. Karp the
net proceeds (as defined in the Separation


                                       3



Agreement) of such sale. Pursuant to the Separation Agreement, Mr. Karp has sole
discretion as to when the options are to be exercised and the prices at which
the shares of Common Stock are to be sold. The options to be exercised by Mr.
Karp pursuant to the Separation Agreement and the shares of Common Stock to be
sold on Karen A. Karp's behalf thereunder are to be the first options exercised
and shares of Common Stock sold by Mr. Karp following the date of the Separation
Agreement.

     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. Nevertheless, depending on market conditions and other
factors, Mr. Karp may purchase additional shares of Common Stock (upon the
exercise of options and otherwise) and may sell or otherwise dispose of shares
of Common Stock, including but not limited to purchases and sales of Common
Stock for estate planning purposes.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to
        ------------------------------------------------------------------------
        Securities of the Issuer.
        ------------------------

     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 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


                                       7



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
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.

     Pursuant to the Inducement Option, Mr. Karp has exercised options to
purchase 2,000,000 shares of Common Stock.

     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.

     Pursuant to the Subsequent Option, Mr. Karp has exercised options to
purchase 45,000 shares of Common Stock.

     The Subsequent Option is filed as Exhibit B to this Statement.

     Mr. Karp is party to a Separation Agreement pursuant to which Karen A. Karp
has the right to the net proceeds from the sale by Mr. Karp of 200,000 shares of
Common Stock. See Item 4 to this Schedule 13D.
