Exhibit 99.1 	AGREEMENT (this Agreement), dated as of June 5, 2006, between The Washington Post Company, a Delaware corporation (Parent), and Jonathan N. Grayer (the Executive). 		WITNESSETH: 	WHEREAS, the parties hereto wish to establish the equity compensation arrangements for the Executive for the years 2006 through and including 2011 in connection with assuring the Executives continued employment as Chairman and Chief Executive Officer of Kaplan, Inc. (the Company), a Delaware corporation and subsidiary of Parent. 	NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein, the parties hereto agree as follows: 		ARTICLE I 		DEFINITIONS 	SECTION 1.01. Definitions. As used in this Agreement, the following terms shall have the meanings ascribed to them below: 	Chief Executive Officer shall mean the Chief Executive Officer of Parent. 	Common Stock shall mean common stock, par value $1.00 per share, of the Company. 	Compensation Committee shall mean the Compensation Committee of the Board of Directors of Parent. 	Current Fair Market Value shall mean $1,833.00 per share of Common Stock, which the Compensation Committee has determined to be the Fair Market Value of the Common Stock as of the date hereof. 	Disability shall have the meaning assigned thereto in the Stock Option Plan. 	Fair Market Value shall mean, as of any date, the value of the Common Stock determined as follows: (i) if the Common Stock is listed on any established stock exchange or a national market system, including without limitation The Nasdaq National Market or The Nasdaq SmallCap Market of The Nasdaq Stock Market, its Fair Market Value shall be the mean between the high and low sale prices for the Common Stock (or the closing bid, if no sales were reported) as quoted on such exchange or system for the last market trading day prior to the time of determination, as reported in The Wall Street Journal or such other source as the Board of Directors of the Company deems reliable, or if the Common Stock is regularly quoted by a recognized securities dealer but selling prices are not reported, their Fair Market Value shall be the mean between the high bid and low asked prices for the Common Stock on the last market trading day prior to the day of determination; or 	(ii) in the absence of an established market for the Common Stock, the aggregate Fair Market Value thereof shall be determined at least once a year on or before the first day of February and at such other times as may be deemed appropriate by the Compensation Committee in its sole discretion. As part of its determination, the Compensation Committee shall (1) obtain and consider a professional appraisal of the value of the Company from an investment bank or from another entity capable of preparing such valuation; and (2) use or cause to be used methodologies such as those used by Goldman Sachs in each of its 1997-2005 valuations of the Company, including a multiple of earnings, present value of future cash flows or such other established methodologies that value comparable enterprises as going concerns. However, both the recommendation of the professional appraisal and the result of the application of such methodologies shall only be advisory to the Compensation Committee and not determinative of the value of the Company. The Compensation Committee shall have the right, in its sole discretion, to retain and make use of any advisory assistance it deems necessary or desirable in preparing the valuations of the Company, including, but not limited to, the right to appoint a new appraiser. The Fair Market Value of each share of Common Stock shall be determined by dividing the aggregate Fair Market Value by the number of then-outstanding shares of Common Stock plus the number of shares of Common Stock reserved for issuance under and pursuant to the terms of the Companys stock option plans. 	Options shall mean options granted under the Stock Option Plan to purchase shares of Common Stock. 	Pre-Compensation Operating Income shall mean the annual operating income of the Company, after deductions for annual cash bonuses, but not including any deductions for long-term compensation plans or the Stock Option Plan. 	Stockholders Agreement shall mean the Stockholders Agreement, dated as of June 5, 2006, among Parent, the Company and the Executive. 	Stock Option Plan shall mean the Fifth Amended and Restated Stock Option Plan of the Company, as amended from time to time. 		ARTICLE II 	 EQUITY ARRANGEMENTS 	SECTION 2.01. Initial Grant. (a) Promptly after execution by the Executive of the Stockholders Agreement, Parent will cause the Company to issue to the Executive 2,619 shares of Common Stock (the Initial Grant), representing approximately $4,800,000 of Common Stock based on the Current Fair Market Value thereof. Parent and the Executive agree that the Initial Grant shall be made in lieu of the Executives 2005 bonus. (b) In connection with the Initial Grant, the Executive shall be entitled to exercise a number of Options (the Exercised Options) currently held by the Executive that will, after the repurchase by Parent of the shares of Common Stock underlying such Options as set forth below, generate net proceeds to the Executive in an amount approximately equal to the Executives tax liability arising from the Initial Grant. Parent and the Executive agree that the Exercised Options relate to 3,364 shares of Common Stock of the Company. Upon exercise of the Exercised Options, (i) Parent will repurchase the shares of Common Stock received by the Executive in connection therewith at the Current Fair Market Value and (ii) Parent will cause the Company to grant the Executive a number of additional Options (the Reload Options) equal to the number of Exercised Options. The exercise price of the Reload Options will be the Current Fair Market Value. The Reload Options will vest over a period of four years, with 25% of the Reload Options vesting on each of January 1, 2007, January 1, 2008, January 1, 2009 and January 1, 2010. 	SECTION 2.02. Additional Options. (a) Promptly after execution by the Executive of the Stockholders Agreement, Parent will cause the Company to grant the Executive 14,182 additional Options (the Additional Options). The exercise price of the Additional Options will be the Current Fair Market Value. Subject to Section 2.02(b), the Additional Options will vest over a period of four years, with 25% of the Additional Options vesting on each of December 31, 2007, December 31, 2008, December 31, 2009 and December 31, 2010; provided, however, that such Additional Options shall not be exercisable unless and until the Companys Pre-Compensation Operating Income for any of the fiscal years ending December 31, 2009, December 31, 2010 or December 31, 2011 shall have been equal to or greater than a minimum performance standard, as established by the Chief Executive Officer and the Compensation Committee. (b) Notwithstanding Section 2.02(a), in the event of the Executives (i) termination (other than termination for cause, which shall be defined as willful misconduct that remains uncured for more than sixty (60) days following written notice and results in material reputational or economic injury to the Company) or (ii) death or Disability, all of the Additional Options held by the Executive shall immediately vest and become exercisable by the Executive (or his estate). 	SECTION 2.03. Future Grants. (a) For each of 2006 through 2011, if Kaplan delivers Pre-Compensation Operating Income equal to or greater than special target amounts determined by the Chief Executive Officer and the Compensation Committee, Parent will cause the Company to issue to the Executive a number of shares of Common Stock valued at the dollar amount that would otherwise have been paid to him as a cash bonus for Kaplans meeting the applicable special target level, based on the Fair Market Value thereof as of the date of issuance. (b) The Executive shall be eligible for additional grants of Common Stock for each of 2006 through 2011, at the discretion of the Chief Executive Officer and the Compensation Committee, based upon truly exceptional performance by the Company in the preceding year, and in lieu of amounts that would otherwise have been paid to him as a cash bonus for such exceptional performance. 	SECTION 2.04. Put Right; Stockholders Agreement. Executive shall have the right to put to the Company all shares of Common Stock held by the Executive, whether pursuant to the Initial Grant, any Future Grant, upon exercise of Options or otherwise, utilizing the procedures set forth in Section 6(k)(1) of the Stock Option Plan (Put Right), and as a result thereof the Executive shall have the right to sell any or all of such shares of Common Stock to the Company pursuant to, and in accordance with, such Section 6(k)(1). All such shares of Common Stock shall be subject to the terms and conditions of the Stockholders Agreement. 		ARTICLE III 	 OTHER AGREEMENTS 	SECTION 3.01. Non-Competition. For a period of three years from the date the Executives employment with the Company terminates, the Executive will not compete directly against any non-trivial business in which Parent and its subsidiaries are then engaged, which shall mean not participating actively in the management or supervision of a directly competing enterprise. The foregoing is not intended to prevent the Executive from working in the same lines of business as those in which Parent and its subsidiaries are also engaged (e.g., education, media) unless the competitive overlap with Parent and its subsidiaries is direct and substantial. 	SECTION 3.02. No Solicitation. For a period of two years from the date the Executives employment by the Company terminates, the Executive will not solicit any then-current employees of the Company to join the Executive in another enterprise or activity. 	SECTION 3.03. Interpretation. It is intended by the parties hereto that, in the event of the need for interpretation of Section 3.01 or 3.02, Parents appointed representative to discuss with Executive the interpretation of Section 3.01 or 3.02 shall be Mr. Donald E. Graham, for so long as Mr. Graham is a director of Parent and, thereafter, by a director of Parent chosen by the Executive. Such interpretation shall be made taking into account the purpose of Sections 3.01 and 3.02, which is not to penalize Executive, or needlessly circumscribe Executives future, but to protect Parent and its subsidiaries from direct and material harm; Sections 3.01 and 3.02 shall not prevent the Executive from pursuing a normal business career because of de minimis conflicts.
