INDEPENDENT AUDITORS' REPORT

To the Board of Directors of PRIMEDIA Inc.
and Participants of the PRIMEDIA Employee Stock Purchase Plan
New York, New York

        We have audited the accompanying statements of net assets of the PRIMEDIA Employee Stock Purchase Plan (the "Plan") as of December 31, 2003 and 2002, and the related statements of changes in net assets for the years ended December 31, 2003, 2002 and 2001. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits.

        We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, such financial statements present fairly, in all material respects, the net assets of the Plan as of December 31, 2003 and 2002, and the changes in net assets for the years ended December 31, 2003, 2002 and 2001, in conformity with accounting principles generally accepted in the United States of America.

PRIMEDIA Inc.
PRIMEDIA Employee Stock Purchase Plan

Notes to Financial Statements

1.     DESCRIPTION OF THE PLAN:

        The following description of the PRIMEDIA Inc. (the "Company") PRIMEDIA Employee Stock Purchase Plan, (the "Plan"), provides only general information. Participants should refer to the Plan document for a more complete statement of the Plan's provisions.

        The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of additions and deductions during the reporting year. Actual results could differ from those estimates.

        The Plan is an employee stock purchase plan that allows participants to purchase shares of the Company's Common Stock ("Stock") through payroll deductions. The Plan's fiscal year is divided into two six-month periods ("Offering Periods"). The Offering Periods are January 1 to June 30 and July 1 to December 31 and represent the periods during which participants' payroll deductions are accumulated. At the end of each Offering Period, the participants' accumulated payroll deductions are used to purchase shares of Stock. Participants may purchase shares of Stock for an amount equal to 90% of the lesser of (1) the closing price of a share of Stock on the first day of the Offering Period or (2) the closing price of a share of Stock on the last day of the Offering Period ("Purchase Price"). The corresponding date upon which the share calculation is based is herein referred to as the Purchase Price Date.

        Effective January 1, 2004 and for the Offering Periods thereafter, Plan management amended the Plan document to change the Purchase Price from an amount equal to 90% of the lesser of (1) the closing price of a share of Stock on the first day of the Offering Period or (2) the closing price of a share of Stock on the last day of the Offering Period to an amount equal to 90% of the closing price of a share of Stock on the last day of the Offering Period.

        The Plan was approved by the Company's Board of Directors on March 27, 2000. The stock subject to issuance under the Plan shall be authorized but unissued common stock, treasury shares or shares purchased on the open market. The aggregate number of shares, which may be issued pursuant to the Plan, is 5,000,000. At December 31, 2003, including all shares issued and all shares for which payroll deductions are sufficient to purchase Stock, 3,076,770 shares of Stock are available for future purchases by Plan participants.

        The Plan is neither qualified under Section 401(a) of the Internal Revenue Code of 1986, as amended, nor subject to any of the provisions of the Employee Retirement Income Security Act of 1974 (commonly known as "ERISA").

        All full-time or part-time employees of the Company and its eligible subsidiaries, who customarily work at least 20 hours per week and five months a year, are eligible to participate in the Plan. Eligible employees may only enroll in the Plan prior to the beginning of an Offering Period.

5


        On the last trading day of each Offering Period, the amount of each participant's accumulated payroll deductions is applied towards the purchase of the maximum number of whole and fractional shares of Stock possible, determined by dividing the participant's total contribution by the per share Purchase Price applicable for that Offering Period. Purchased shares of Stock are transferred to a brokerage account in the name of the participant at a securities brokerage firm approved by a committee appointed by the Board of Directors of the Company.

        Participants may elect to have 2% to 5% of their "Base Salary" (as defined in the Plan) deducted on an after-tax basis for the purchase of Stock. Participants may only increase or decrease their deduction percentages prior to the beginning of an Offering Period and may not decrease their deductions during the Offering Period except to stop contributing. No interest accrues or is paid on participants' accumulated payroll deductions. Once made, the Company may use the payroll deductions for any corporate purpose, and the Company has no obligation to segregate employees' payroll deductions from any other funds of the Company or to hold funds representing the same pending the application thereof to the purchase of shares at the end of each Offering Period in accordance with the Plan.

        Plan participants may withdraw from the Plan prior to the last day of an Offering Period by properly notifying the Company. A participant's accumulated payroll deductions for the Offering Period prior to withdrawal from the Plan will be promptly refunded to the participant without interest (unless required by law). In addition, Plan participants can elect to stop future contributions and leave contributions already made in the current Offering Period in the Plan (to purchase shares at the end of the Offering Period) by properly notifying the Company at specified times prior to the last day of an Offering Period.

        Participants who terminate their employment relationship with the Company are not eligible to continue in the Plan. All payroll deductions accumulated during the Offering Period through the date of such cessation of employment are refunded to the employee or, in the event of the employee's death, to the beneficiary designated by the participant on his/her Enrollment/Change Form.

        The Company bears all costs in connection with the Plan including administrative fees and all fees associated with the issuance of Stock. The Plan participant is responsible for all brokerage and related expenses associated with the sale of Stock.

        Administrative expenses related to the Plan amounted to approximately $28,000, $28,000 and $34,000 for the years ended December 31, 2003, 2002 and 2001, respectively.

        The Plan may be terminated at any time by the Company's Board of Directors but such termination shall not affect shares then outstanding under the Plan. If at any time shares of Stock reserved for the purpose of the Plan remain available for purchase but not in sufficient number to satisfy all then unfilled purchase requirements, the available shares shall be apportioned among participants in proportion to the amount of payroll deductions accumulated on behalf of each participant that would otherwise be used to purchase Stock, and the Plan shall terminate. Upon such

termination or any other termination of the Plan, all payroll deductions not used to purchase stock will be refunded, without interest (unless required by law).

2.     INCOME TAX STATUS:

        The Plan appears to satisfy the requirements of an "employee stock purchase plan" as defined under Section 423 of the Internal Revenue Code of 1986, as amended. As such, the Plan is not required to file income tax returns or pay income taxes. Under Section 423, a participating employee will generally not recognize taxable income, and the Company will generally not be entitled to a tax deduction for federal income tax purposes when an employee enrolls in the Plan or when a participant purchases shares of Stock under the Plan.

3.     SUBSEQUENT EVENTS:

        Subsequent to December 31, 2003, $497,559 of the accumulated deductions were used to purchase 195,351 shares of Stock which were issued to participants by the Company in January 2004. The 195,351 shares of Stock purchased subsequent to December 31, 2003 had a market value of $552,843 as of the Purchase Price Date.
