                                    SUMMARY

    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND THE CONSOLIDATED FINANCIAL STATEMENTS AND ACCOMPANYING NOTES
INCORPORATED BY REFERENCE IN THIS PROSPECTUS. UNLESS THE CONTEXT OTHERWISE
INDICATES, THE TERM "WE" OR "PRIMEDIA" MEANS THE COMBINED BUSINESS OPERATIONS OF
PRIMEDIA INC. AND ITS SUBSIDIARIES. YOU SHOULD CAREFULLY CONSIDER THE RISKS
INCLUDED UNDER THE CAPTION "RISK FACTORS." MARKET SHARE DATA CONTAINED IN THIS
PROSPECTUS ARE BASED UPON A PRODUCT'S SHARE OF ADVERTISING OR CIRCULATION,
DEPENDING ON THE PRODUCT, AS COMPARED TO ITS DIRECT COMPETITION.

                                  OUR COMPANY

    PRIMEDIA is the new tradition in media, combining traditional and new media.
We are a targeted media company with leading positions in consumer and
business-to-business markets. Our properties, which are delivered to over
200 million users, utilize the full media arsenal to deliver content via print
(magazines and directories), video (digital broadband, satellite and cable),
live events (trade and consumer shows) and the Internet. As of December 31,
2000, approximately 78% of our traditional media products ranked first or second
in advertising pages, advertising revenue, circulation or other competitive
metrics in their respective markets. We believe that in 2000 we sold the most
advertising pages of any magazine publisher in the United States and ranked
third in terms of revenue derived from sales of magazine copies at the newsstand
in the United States. Our Internet businesses rank seventh in unique visitors in
the United States as measured by MEDIA METRIX for June 2001.

    In 2000, we had net sales of approximately $1.7 billion and EBITDA of
approximately $256.7 million. For the six months ended June 30, 2001, we had net
sales of approximately $872.3 million and EBITDA of approximately
$86.2 million. In 2000, our net loss was approximately $346.8 million, and for
the six months ended June 30, 2001, our net loss was approximately
$225.5 million.

                              OUR GROWTH STRATEGY

    We believe that as technology has created a flood of information, it has
shifted the role of the media from making information broadly available across
all audiences to sifting out and qualifying information for the benefit of
specific audiences. As a result, we have organized our business into two
operating segments: consumer and business-to-business. Our consumer segment is
the largest publisher of specialty magazines and apartment rental guides and one
of the largest producers and distributors of special interest videos in the
United States. Through the About.com merger, we acquired a network of
highly-targeted, topic-specific web sites and the leading producer of original
content on the Internet. Our business-to-business segment is a leading publisher
of business-to-business magazines, books, directories and databases, addressing
the specialized information needs of professionals.

    Our growth strategy is to deliver information over multiple traditional and
new media platforms to highly specific niches in both the consumer and
business-to-business markets, thereby attracting both dedicated users of
information and the advertisers determined to reach them. We expect to derive
our revenue principally from lead generation advertising as well as from
subscriptions to our products and brand awareness advertising. Lead generation
advertising is advertising focused on triggering a purchase decision by the
reader or viewer. We believe lead generation advertising is less susceptible to
general economic conditions than general brand awareness advertising.

    In 2000, we embarked on an initiative to integrate our operating units. One
aspect of the integration was to improve productivity through cost reduction as
we entered into a strategic sourcing initiative to leverage our purchasing power
across all spending for certain manufacturing and non-manufacturing commodities.
Significant cost savings were achieved through consolidating the procurement of
goods and services, such as paper and printing, and centralizing support
services, such as accounting and payroll. During 2000, the strategic sourcing
initiative generated approximately

                                       1
<Page>
$10.5 million in savings. With the About.com merger, we will continue our
integration and sourcing efforts and expect to reduce Internet development
costs.

    After the About.com merger, we formed the PRIMEDIA Integrated Sales and
Marketing Group to sell integrated marketing packages across all our traditional
and new media vehicles. We also formed the PRIMEDIA Internet Resource and
Technology Group to centralize and standardize our technology.

                              RECENT DEVELOPMENTS

EMAP USA

    On July 2, 2001, we entered into a definitive agreement to acquire
EMAP, Inc. (formerly known as Petersen Publishing) from EMAP plc. In this
prospectus, we refer to EMAP, Inc. as EMAP USA. EMAP USA has more than 60
consumer titles reaching over 75 million enthusiasts through a combination of
magazines, network and cable television shows, web sites and live consumer
events. Upon completion of this acquisition, we will be the second largest
magazine company in the United States. Under the terms of our agreement, we will
pay $515 million for EMAP USA, consisting of $505 million in cash and warrants
granted to an affiliate of EMAP plc to purchase 2 million of our shares of
common stock at $9 per share. The transaction is subject to customary closing
conditions and is expected to close during August 2001. The acquisition does not
include the United States edition of FOR HIM MAGAZINE published by EMAP USA.

    We believe that our acquisition of EMAP USA will, among other things:

    - add significant scale to one of our strongest niche sectors, the
      automotive enthusiast market, and make us more attractive to the new car
      automotive advertising market as a result of the combination of EMAP USA's
      MOTOR TREND magazine and our existing automobile titles;

    - strengthen our position in the teen market with the addition of EMAP USA's
      TEEN magazine;

    - add higher growth categories to our enthusiast magazine business, namely
      EMAP USA's high tech and action sports titles;

    - enhance our position as the leading provider of niche topic video in the
      United States through the addition of five more weekly cable television
      programs;

    - enable us to further amortize our About.com Internet infrastructure; and

    - achieve efficiencies as a result of our increased scale of operations in
      the areas of paper purchasing, circulation, production, technology,
      finance and others.

NEW CREDIT AGREEMENT

    On June 20, 2001, we entered into a new credit agreement with commitments of
$1 billion, of which $558 million was outstanding as of June 30, 2001. The debt
under the credit agreement (as well as certain of our other equally and ratably
secured indebtedness) is secured by a pledge of the stock of PRIMEDIA
Companies Inc., an intermediate holding company that we own directly.

                                       2

    The following chart summarizes the businesses of our two segments:

                                     [LOGO]

- ------------------------
*    Subject to completion of the acquisition, EMAP USA will be included in our
     consumer segment. EMAP USA has more than 60 consumer titles, including
     MOTOR TREND, HOT ROD, TEEN and STEREOPHILE.

    We were incorporated on November 22, 1991 in the State of Delaware. Our
principal executive offices are located at 745 Fifth Avenue, New York, New York,
10151; telephone number (212) 745-0100. Our domain name is "primedia.com." Our
common stock is publicly traded on the New York Stock Exchange under the symbol
"PRM." The information on our web site is not part of this prospectus.

<Page>
                            CONCURRENT TRANSACTIONS

    We intend to partially finance the acquisition of EMAP USA and related
expenses by (1) entering into a $125 million preferred equity financing, which
will include warrants for our common stock, with an affiliate of Kohlberg Kravis
Roberts & Co. L.P., or KKR, which directly or indirectly owns a majority of our
outstanding shares of common stock, (2) drawing upon our revolving credit
facility in an amount of approximately $270 million and (3) consummating a
private placement of shares of our common stock for aggregate cash proceeds of
$125 million, $50 million of which we expect to receive from an affiliate of
KKR. An affiliate of KKR has agreed to provide us with additional equity
financing up to an aggregate of $125 million. In this prospectus, we refer to
these three transactions collectively as the "concurrent transactions." The
remainder of the financing will come from cash on hand and the warrants we
expect to issue to an affiliate of EMAP plc as discussed under "--Recent
Developments--EMAP USA." The shares of our preferred stock and common stock
offered in the concurrent transactions have not been registered and, at the time
of sale, will not be registered under the Securities Act. These shares may not
be offered or sold in the United States absent subsequent registration or an
applicable exemption from registration requirements.

    Pursuant to the preferred equity financing, we intend to issue to KKR or one
of its affiliates shares of preferred stock with an aggregate liquidation
preference of $125 million. We expect that dividends on the preferred stock will
accrue at an annual rate of 12.5% and will be payable quarterly in kind. We
expect the preferred stock to be perpetual and to rank PARI PASSU with our
existing series of outstanding preferred stock. We expect to have the option to
redeem any or all of the shares of preferred stock at any time for cash at 100%
of the liquidation preference of each share being redeemed. We also expect that
the preferred stock will be convertible into shares of our common stock at any
time after the first anniversary of the issue date at a conversion price of $7
per share, subject to adjustments. We also expect to have the option to cause at
any time the convertible preferred stock to be exchanged into subordinated debt
of ours. Our ability to redeem or exchange the convertible preferred stock into
debt will be subject to the approval of a majority of our independent directors.

    In connection with the equity financing to be made available to us by KKR,
we expect to pay KKR or one of its affiliates a commitment fee consisting of
warrants to purchase 1.25 million shares of our common stock and grant to KKR or
one of its affiliates additional warrants to purchase up to 6.62 million shares
of our common stock. We expect the warrants to be exercisable at any time after
the first anniversary of the grant date at a price of $7 per share, subject to
adjustments. We expect that the warrants constituting the commitment fee and
additional warrants to purchase 2.62 million shares of our common stock will
vest on the grant date, whereas warrants to purchase up to 4 million shares will
be subject to a vesting schedule pursuant to which warrants for 250,000 shares
will vest on the three-month anniversary of the grant date, warrants for an
additional 1 million shares will vest on the six-month anniversary of the grant
date, warrants for an additional 1.25 million shares will vest on the nine-month
anniversary of the grant date and the remaining warrants will vest on the
12-month anniversary of the grant date. Any unvested warrants of those subject
to the vesting schedule will expire if we redeem all the outstanding shares of
convertible preferred stock.

    We expect that the proceeds from the sale of certain assets, expected to be
$250 million, will be used to reduce the leverage of our company. These assets
are currently reported as continuing businesses.

    For a description of the terms of our revolving credit facility, see
"Description of Other Indebtedness and Preferred Stock--Bank Credit Facilities."

are identical in all material respects to the old notes except:

       - the new notes have been registered under the Securities Act of 1933;
         and

       - the liquidated damages which would be payable on the old notes in
         specified circumstances are no longer applicable.

<Table>
                                    
The Exchange Offer...................  We are offering to exchange up to $500,000,000 aggregate

                                       Exxon Capital Holdings Corporation and Morgan Stanley & Co.
                                       Incorporated, we believe that the new notes issued in the
                                       exchange offer in exchange for old notes may be offered for
                                       resale, resold and otherwise transferred by you without
                                       compliance with the registration and prospectus delivery
                                       provisions of the Securities Act, so long as you:

                                         in, and have no arrangement or understanding with any
                                         person to participate in, a distribution of the new notes.

                                       Each participating broker-dealer that receives new notes for
                                       its own account in the exchange offer in exchange for old
                                       notes that were acquired as a result of market-making or
                                       other trading activity must acknowledge that it will deliver
                                       a prospectus in connection with any resale of the new notes.

                                         business; or

                                       - if you are a broker-dealer that will receive new notes for
                                         your own account in exchange for old notes that were
                                         acquired as a result of market-making activities, that you
                                         will deliver a prospectus, as required by law, in
                                         connection with any resale of those new notes; and

                                         prospectus delivery requirements of the Securities Act.

Special Procedures for Beneficial
Owners...............................  If you are a beneficial owner of old notes which are
                                       registered in the name of a broker, dealer, commercial bank,
                                       trust company or other nominee and you wish to tender your
                                       old notes in the exchange offer, you should contact that
                                       registered holder promptly and instruct the registered
                                       holder to tender on your behalf. If you wish to tender on
                                       your own behalf, you must, prior to completing and executing
                                       the letter of transmittal and delivering your old notes,
                                       either make appropriate arrangements to register ownership
                                       of the old notes in your name or obtain a properly completed
                                       bond power from the registered holder. The transfer of
                                       registered ownership may take considerable time and may not
                                       be able to be completed before the expiration date.

Guaranteed Delivery
Procedures...........................  If you wish to tender your old notes and your old notes are
                                       not immediately available or you cannot deliver your old
                                       notes, the letter of transmittal or any other documents
                                       required by the letter of transmittal or to comply with the
                                       applicable procedures under DTC's Automated Tender Offer
                                       Program before the expiration date, you must tender your old
                                       notes according to the guaranteed delivery procedures set
                                       forth in this prospectus under "The Exchange
                                       Offer--Guaranteed Delivery Procedures."

Effect on Holders of
Outstanding Notes....................  Once we complete the exchange of all validly tendered old
                                       notes pursuant to the terms of the exchange offer, we will
                                       have fulfilled a covenant contained in the registration
                                       rights agreement and, accordingly, there will be no
                                       liquidated damages paid on the old notes under the
                                       circumstances described in the registration rights
                                       agreement. If you are a holder of old notes and you do not
                                       tender your old notes in the exchange offer, you will
                                       continue to hold the old notes and you will be entitled to
                                       all the rights and limitations applicable to the old notes
                                       in the indenture, except for any rights under the
                                       registration rights agreement that by their terms terminate
                                       upon the completion of the exchange offer.

                                       We expect that the exchange of new notes for old notes will
                                       have a material adverse effect on the trading market for old
                                       notes.

Consequences of Failure to
Exchange.............................  All untendered old notes will continue to be subject to the
                                       restrictions on transfer provided for in the old notes and
                                       in the indenture. In general, the old notes may not be
                                       offered or sold, unless registered under the Securities Act,
                                       except pursuant to an exemption from, or in a transaction
                                       not subject to, the Securities Act and applicable state
                                       securities laws. Other than in connection with the exchange
                                       offer, we do not currently anticipate that we will register
                                       the old notes under the Securities Act.

Material Income Tax Considerations...  The exchange of old notes for new notes in the exchange
                                       offer will not be a taxable event for United States federal
                                       income tax purposes. See "Certain United States Federal
                                       Income Tax Consequences."

Use of Proceeds......................  We will not receive any cash proceeds from the issuance of
                                       new notes in connection with the exchange offer.

Exchange Agent.......................  The Bank of New York is the exchange agent for the exchange
                                       offer. The address and telephone number of the exchange
                                       agent are provided in the section captioned "The Exchange
                                       Offer--Exchange Agent" of this prospectus.

                                       wholly-owned domestic restricted subsidiaries, other than

                                       As of June 30, 2001, we had approximately $1,698.9 million
                                       of senior indebtedness consisting of $558.0 million of

                                       As of June 30, 2001, there was $420.4 million available for
                                       borrowing under our bank credit facilities. As a result of
                                       the concurrent transactions, we expect to draw upon our
                                       revolving credit facility in an amount of $270 million.

                                       As of June 30, 2001, we had no subordinated indebtedness

                  SELECTED CONSOLIDATED FINANCIAL INFORMATION

    The selected consolidated operating and balance sheet data are derived in
part from our audited consolidated financial statements contained in our annual
reports on Form 10-K for each of the years in the five-year period ended
December 31, 2000 and from our unaudited condensed consolidated financial
statements contained in our quarterly report on Form 10-Q for the quarter ended
June 30, 2001. The historical data are only a summary and should be read in
conjunction with the historical consolidated financial statements and related
notes contained in the Form 10-K for the year ended December 31, 2000 and the
Form 10-Q for the quarter ended June 30, 2001, which have been incorporated by
reference in this prospectus. In the opinion of management, the unaudited
condensed consolidated financial statements have been prepared on the same basis
as the audited consolidated financial statements and include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the financial position and results of operations for such
periods. The results of operations as of and for the six months ended June 30,
2001 are not necessarily indicative of our results for any other interim period
or for the full year.

- ------------------------------

(1) Represents non-cash compensation and non-recurring charges of $35,210 for
    the year ended December 31, 2000 and $24,544 and $12,727 for the six months
    ended June 30, 2000 and 2001, respectively, a provision for severance,
    closures and integration costs of $22,000 and $20,798 for the years ended
    December 31, 1999 and 2000, respectively, and $16,718 and $12,502 for the
    six months ended June 30, 2000 and 2001, respectively, other integration
    costs related to the About.com merger and other company-wide integration
    efforts of $4,304 for the six months ended June 30, 2001, (gain) loss on the
    sales of businesses and other, net of $138,640, $(7,216), $(235,580) and
    $(14,438) for the years ended December 31, 1997, 1998, 1999 and 2000,
    respectively, and $(28,482) and $(503) for the six months ended June 30,
    2000 and 2001, respectively, and a provision for the impairment of
    long-lived assets of $275,788 for the year ended December 31, 1999.

(2) The adoption of a change in method of accounting for internal use software
    costs effective January 1, 1998 resulted in an increase in operating income
    and an equal decrease in net loss of approximately $12,450, $9,000 and
    $12,500 for the years ended December 31, 1998, 1999 and 2000, respectively.

(3) Represents a provision for the impairment of our investment in CMGI, Inc. of
    approximately $155,500, a provision for the impairment of our investment in
    Liberty Digital, Inc. of approximately $21,900 and a provision for the
    impairment of various PRIMEDIA Ventures' investments of approximately
    $11,200 for the year ended December 31, 2000 and a provision for the
    impairment of various of our investments of approximately $30,800 for the
    six months ended June 30, 2001.

(4) At December 31, 1997, 1998 and 1999, our management determined that no
    adjustment to net deferred income tax assets was required. In prior years,
    management determined that a portion of the net deferred income tax assets
    would likely be realized and accordingly, we recorded an income tax benefit
    of $53,300 in 1996. For the year ended December 31, 1997, we recorded an
    income tax carryback claim of $1,685. In 1999, we recorded income tax
    expense of $6,500 related to a provision for current state and local taxes
    incurred as a result of the gain on the sale of the supplemental education
    group. During 2000, we increased our valuation allowance due to historical
    operating losses and the impairment of investments, resulting in a provision
    for income taxes of $41,200. At December 31, 2000, we

                                       12

    had aggregate net operating and capital loss carryforwards of approximately
    $1,028,000 which will be available to reduce future taxable income.

(5) Represents the write-off of unamortized deferred financing costs and the
    premiums paid on the redemptions of the 10 5/8% senior notes.

(6) Includes the premiums paid on the redemptions of our $11.625 Series B
    exchangeable preferred stock and our $2.875 senior exchangeable preferred
    stock in 1998 and 1997, respectively. In 1997, we recorded a preferred stock
    dividend accrual in the amount of $9,517. Of the total dividend accrual
    recorded in 1997, the amounts that relate to prior periods were not
    material.

(7) Represents earnings before interest, taxes, depreciation, amortization and
    other (income) charges including non-cash compensation and non-recurring
    charges of $35,210 for the year ended December 31, 2000 and $24,544 and
    $12,727 for the six months ended June 30, 2000 and 2001, respectively, a
    provision for severance, closures and integration costs of $22,000 and
    $20,798 for the years ended December 31, 1999 and 2000, respectively, and
    $16,718 and $12,502 for the six months ended June 30, 2000 and 2001,
    respectively, other integration costs related to the About.com merger and
    other company-wide integration efforts of $4,304 for the six months ended
    June 30, 2001, (gain) loss on the sales of businesses and other, net of
    $138,640, $(7,216), $(235,580) and $(14,438) for the years ended
    December 31, 1997, 1998, 1999 and 2000, respectively, and $(28,482) and
    $(503) for the six months ended June 30, 2000 and 2001, respectively, and a
    provision for the impairment of long-lived assets of $275,788 for the year
    ended December 31, 1999.

   EBITDA is not intended to represent cash flow from operating activities and
    should not be considered as an alternative to net income (loss) (as
    determined in conformity with generally accepted accounting principles) as
    an indicator of our operating performance or to cash flows as a measure of
    liquidity. We believe EBITDA is a standard measure commonly reported and
    widely used by analysts, investors and other interested parties in the media
    industry. Accordingly, this information has been disclosed in this
    prospectus to permit a more complete comparative analysis of our operating
    performance relative to other companies in our industry. EBITDA should not
    be considered in isolation or as a substitute for other measures of
    financial performance or liquidity. The primary difference between EBITDA
    and cash flows provided by operating activities relates to changes in
    working capital requirements and payments made for interest and income
    taxes. Additionally, EBITDA is not available for our discretionary use as
    there are legal requirements to pay preferred stock dividends and repay
    debt, among other payments. EBITDA as presented may not be comparable to
    similarly titled measures reported by other companies, since not all
    companies necessarily calculate EBITDA in identical manners, and therefore,
    is not necessarily an accurate measure of comparison between companies.

(8) For purposes of determining the deficiency of earnings to fixed charges and
    preferred stock dividends and related accretion, "earnings" consist of loss
    before income taxes, fixed charges and equity in losses of investees, and
    "fixed charges" consist of interest on all indebtedness, amortization of
    deferred financing costs and that portion of rental expenses that management
    believes to be representative of interest and "preferred stock dividends and
    related accretion" consist of dividends on our preferred stock, the
    accretion of our preferred stock and premiums paid on the redemption of our
    $11.625 Series B exchangeable preferred stock in 1998.

(9) Loss before income taxes includes non-cash and non-recurring charges for
    depreciation and amortization of property and equipment, other intangible
    assets, excess of purchase price over net assets acquired and deferred
    financing costs, gain (loss) on the sales of businesses and other, net,
    provision for severance, closures and integration costs, non-cash
    compensation and non-recurring charges, provision for the impairment of
    long-lived assets, provision for the impairment of investments, write-off of
    deferred financing costs and non-cash interest expense on an acquisition
    obligation, distribution advance and other current liabilities. These
    charges totaled $198,895, $333,219, $224,063, $294,982 and $419,144 for the
    years ended December 31, 1996, 1997, 1998, 1999 and 2000, respectively and
    $109,999 and $218,055 for the six months ended June 30, 2000 and 2001,
    respectively. Adjusted to eliminate those charges, earnings would have
    exceeded fixed charges and fixed charges plus cash preferred stock dividends
    and related accretion by $163,192 and $136,248, $174,095 and $113,473,
    $186,327 and $123,042, $181,369 and $128,307 and $123,655 and $70,592 for
    the years ended December 31, 1996, 1997, 1998, 1999 and 2000, respectively,
    and by $64,224 and $37,693 for the six months ended June 30, 2000. Adjusted
    to eliminate those charges for the six months ended June 30, 2001, earnings
    would have exceeded fixed charges by $21,872 but, earnings would have been
    insufficient to cover fixed charges plus preferred stock dividends and
    related accretion by $5,475.

                                  RISK FACTORS
                     RISK FACTORS RELATING TO OUR BUSINESS

   WE MAY NOT BE ABLE TO ACHIEVE THE EXPECTED RESULTS FROM THE MERGER WITH
   ABOUT.COM, OUR CONTEMPLATED ACQUISITION OF EMAP USA OR ANY FUTURE
   ACQUISITIONS AND INVESTMENTS.

    We may not be able to continue to integrate the business of About.com or
integrate the business of EMAP USA into our existing businesses without
encountering difficulties. In addition, we may make acquisitions and investments
in the future. The integration of About.com, EMAP USA and other businesses we
may acquire is and will be a complex, time consuming and expensive process
involving a number of issues, including:

    - difficulty integrating acquired technologies, operations and personnel
      with our existing businesses;

    - diversion of management attention in connection with both negotiating the
      acquisitions and integrating the assets;

    - strain on managerial and operational resources as management tries to
      oversee larger operations;

    - exposure to unforeseen liabilities of acquired companies;

    - potential issuance of securities in connection with a future acquisition
      with rights that are superior to the rights of holders of our currently
      outstanding securities; and

    - the requirement to record potentially significant additional future
      operating costs for the amortization of certain intangible assets.

    Our future operating results will depend to a significant degree on our
ability to address these issues. In addition, we have invested and may invest in
the future in some early-stage companies with limited operating histories and
limited or no revenues. We may not be able to successfully develop these young
companies and, in some cases, we may not own enough equity in them to control
their development.

    GENERAL ECONOMIC TRENDS MAY REDUCE OUR ADVERTISING REVENUES.

    Our advertising revenues are subject to the risks arising from adverse
changes in domestic and global economic conditions. A decline in the level of
business activity of our advertisers has had and could continue to have an
adverse effect on our revenues and profit margins. Because of the recent
economic slowdown in the United States, many advertisers, particularly
business-to-business advertisers, are reducing advertising expenditures. If the
current economic slowdown continues or worsens, our results of operations may be
adversely affected.

   WE HAVE SUBSTANTIAL INDEBTEDNESS AND OTHER MONETARY OBLIGATIONS, WHICH
   CONSUME A SUBSTANTIAL PORTION OF THE CASH FLOW THAT WE GENERATE.

    We have substantial indebtedness and expect to incur additional indebtedness
under our bank credit facilities or otherwise. As of June 30, 2001, we had
approximately $1,728.3 million of outstanding indebtedness and $562.1 million of
outstanding preferred stock. In addition, as a result of the concurrent
transactions, we expect to draw upon our revolving credit facility in an amount
of $270 million. A substantial portion of our cash flow is dedicated to the
payment of principal and interest on indebtedness and to the payment of
dividends on our preferred stock, which reduces funds available for capital
expenditures and business opportunities and may limit our ability to respond to
adverse developments in our business or in the economy. For the year ended
December 31, 2000, we paid $117.7 million of principal and $141.9 million of
interest, and for the six months ended June 30,

                                       14
<Page>
2001, we paid $59.8 million of interest. In addition, for the year ended
December 31, 2000, we made cash dividend payments of $53.1 million on our
outstanding preferred stock, and for the six months ended June 30, 2001, we made
cash dividend payments of $26.5 million on our outstanding preferred stock. As a
result of the concurrent transactions, we expect our annual interest payments to
increase by approximately $15 million.

    As of June 30, 2001, borrowings under our bank credit facilities were
approximately $558 million. In addition, to partially finance our acquisition of
EMAP USA, we expect to borrow an additional $270 million under our revolving
credit facility. These borrowings bear interest at floating rates based on the
federal funds rate, the prime lending rate or LIBOR. Increases in interest rates
on indebtedness under our bank credit facilities would increase our interest
payment obligations and could have an adverse effect on us. The weighted average
interest rate on our bank credit facilities was 6.46% at June 30, 2001.

    Our ability to make payments with respect to our indebtedness will depend on
our future operating performance, which will be affected by prevailing economic
conditions and financial, business, competitive and other factors. We will not
be able to control many of these factors, such as the economic conditions in the
markets in which we operate and initiatives taken by our competitors.

    Based on the outstanding principal amount of our debt under our bank credit
facilities and outstanding senior notes as of June 30, 2001, we will be required
to repay $127.4 million of indebtedness on or prior to December 31, 2004, and we
will have to repay substantial additional indebtedness and redeem a significant
amount of preferred stock thereafter. We may not be able to repay that debt or
redeem the preferred stock from available cash sources and may not be able to
refinance that debt or preferred stock on commercially reasonable terms, if at
all. If we are unable to repay, redeem or refinance these amounts on or prior to
their due dates, we may need to sell assets or take other actions that could be
detrimental to the holders of our common stock. In that event, we may not be
able to generate sufficient cash from asset sales to satisfy our cash needs. If
we are unable to repay, redeem or refinance our indebtedness and preferred stock
on or prior to their due dates, we will be in default and all of our
indebtedness could be accelerated.

   OUR DEBT INSTRUMENTS LIMIT OUR BUSINESS FLEXIBILITY BY IMPOSING OPERATING AND
   FINANCIAL RESTRICTIONS ON OUR OPERATIONS.

    The agreements governing our indebtedness impose specific operating and
financial restrictions on us. These restrictions prohibit or limit us from,
among other things:

    - changing the nature of our business;

    - incurring additional indebtedness;

    - creating liens on our assets;

    - selling assets;

    - engaging in mergers, consolidations or transactions with our affiliates;

    - making investments in or loans to specific subsidiaries;

    - making guarantees or specific restricted payments; and

    - declaring or making dividend payments on our common or preferred stock.

    As of June 30, 2001, under our most restrictive debt covenants, we must
maintain a minimum interest coverage ratio of 1.80 to 1 and a minimum fixed
charge coverage ratio of 1.05 to 1. Our maximum allowable debt leverage ratio is
6.0 to 1. The minimum interest coverage ratio and maximum debt coverage ratio we
must maintain become more restrictive over time. The maximum leverage ratio

                                       15
<Page>
decreases to 5.75 to 1, 5.5 to 1, 5.0 to 1 and 4.5 to 1, respectively, on
July 1, 2003, January 1, 2004, January 1, 2005 and January 1, 2006. The minimum
interest coverage ratio increases to 2.0 to 1, 2.25 to 1 and 2.5 to 1,
respectively, on July 1, 2003, January 1, 2004 and January 1, 2005. For the
twelve months ended June 30, 2001, our interest coverage ratio, fixed charge
coverage ratio and debt leverage ratio were 2.34 to 1, 1.28 to 1 and 5.43 to 1,
respectively. These restrictions, in combination with our leveraged nature,
could limit our ability to effect future acquisitions or financings or otherwise
restrict corporate activities.

    Our failure to comply with the terms and covenants in our indebtedness could
lead to a default under the terms of those documents, which would entitle the
lenders to accelerate the indebtedness and declare all amounts owed due and
payable. Moreover, the instruments governing almost all of our indebtedness,
including the notes, contain cross-default provisions so that a default under
any of our indebtedness may result in a default under our other indebtedness. If
a cross-default occurs, the maturity of almost all of our indebtedness could be
accelerated and become immediately due and payable. We may not be able to comply
with these restrictions in the future, or in order to comply with these
restrictions we may have to forgo opportunities that might otherwise be
beneficial to us.

   OUR EARNINGS HAVE BEEN INSUFFICIENT TO PAY OUR FIXED CHARGES AND PREFERRED
   STOCK DIVIDENDS.

    Our earnings were inadequate to cover fixed charges and fixed charges plus
preferred stock dividends and related accretion by $295.5 million and
$348.6 million, respectively, for the year ended December 31, 2000 and by
$196.2 million and $223.5 million, respectively, for the six months ended
June 30, 2001. Earnings consist of loss before income taxes, fixed charges and
equity in losses of investees, and fixed charges consist of interest on all
indebtedness, amortization of deferred financing costs and that portion of
rental expenses that management believes to be representative of interest.
Although our earnings were affected by substantial non-cash and non-recurring
charges (including depreciation and amortization of property and equipment,
other intangible assets, excess of purchase price over net assets acquired and
deferred financing costs, write-off of deferred financing costs, gain on the
sales of businesses and other, net, provision for severance, closures and
integration costs, non-cash compensation and non-recurring charges, provision
for the impairment of investments and non-cash interest expense on an
acquisition obligation and other current liabilities of approximately
$419.1 million for the year ended December 31, 2000 and $218.1 million for the
six months ended June 30, 2001), we cannot assure you that our cash flow will be
sufficient in future periods to permit us to make our required payments on our
indebtedness and preferred stock.

   KOHLBERG KRAVIS ROBERTS & CO. L.P., OR KKR, HAS CONTROL OF OUR COMMON STOCK
   AND HAS THE POWER TO ELECT ALL THE MEMBERS OF OUR BOARD OF DIRECTORS AND TO
   APPROVE ANY ACTION REQUIRING STOCKHOLDER APPROVAL.

    As of July 31, 2001, approximately 59.5% of the shares of our common stock
were held by investment partnerships, of which KKR Associates, L.P., a New York
limited partnership, and KKR GP 1996 LLC, a Delaware limited liability company,
each an affiliate of KKR, are the general partners. KKR Associates and KKR GP
1996 have sole voting and investment power with respect to those shares. In
addition, concurrently with this offering, we expect to issue shares of our
common stock with an aggregate value of $50 million to KKR 1996 Fund L.P., an
affiliate of KKR, to issue to KKR or one of its affiliates shares of preferred
stock with an aggregate liquidation preference of $125 million and convertible
into shares of our common stock at any time after the first anniversary of the
issue date at a conversion price per share of $7 and, in connection with the
equity financing to be made available to us by KKR, to grant warrants to KKR or
one of its affiliates to purchase up to 7.87 million shares of our common stock.
As a result of their majority ownership, our stockholders that are affiliated
with KKR and their respective general partners and members, four of whom are
also our directors, control us and have the power to elect all of our directors
and approve any action requiring stockholder approval, including adopting
amendments to our certificate of incorporation and approving mergers or

                                       16
<Page>
sales of all or substantially all of our assets. Our stockholders that are
affiliated with KKR will also be able to prevent change of control events or
cause a change of control at any time. The interest of our KKR affiliated
stockholders and their affiliates may conflict with the interest of holders of
our debt securities, including the new notes.

   INCREASES IN PAPER AND POSTAGE COSTS MAY HAVE AN ADVERSE IMPACT ON OUR FUTURE
   FINANCIAL RESULTS.

    The price of paper is a significant expense relating to our print products
and direct mail solicitations. Paper price increases may have an adverse effect
on our future results. Postage for product distribution and direct mail
solicitations is also a significant expense. We use the U.S. Postal Service for
distribution of many of our products and marketing materials. Postage costs
increased in January 2001 and can be expected to increase in the future. We may
not be able to pass these cost increases through to our customers.

   WE DEPEND ON SOME IMPORTANT EMPLOYEES, AND THE LOSS OF ANY OF THOSE EMPLOYEES
   MAY HARM OUR BUSINESS.

    Our performance is substantially dependent on the performance of our
executive officers and other key employees. In addition, our success is
dependent on our ability to attract, train, retain and motivate high quality
personnel, especially for our management team. Competition for those employees
is intense. The loss of the services of any of our executive officers or key
employees may harm our business.

   OUR TRADITIONAL BUSINESS IS SUBJECT TO COMPETITION FROM THE RAPIDLY
   INCREASING AND COMPETITIVE MARKET FOR NEW MEDIA PRODUCTS AND SERVICES.

    We derive a substantial portion of our revenues from our traditional
businesses. The increased availability of information on the Internet subjects
our traditional business to additional competition, which may adversely affect
our future operating results. Our strategies for obtaining sustained revenue
growth and profitability in the market for new media products and services may
not be sufficient to compensate for any losses of revenue in our traditional
businesses resulting from competition with new media.

    Numerous well-established companies and smaller entrepreneurial companies
are focusing significant resources on developing and marketing products and
services that will compete with our products and services. Competition in the
market for Internet products and services may intensify in the future. In
addition, our current and potential competitors may have greater financial,
technical, operational and marketing resources. Competitive pressures may also
force prices for Internet goods and services down and those price reductions may
adversely affect us.

   IF THE UNITED STATES OR OTHER GOVERNMENTS REGULATE THE INTERNET MORE CLOSELY,
   OUR NEW MEDIA BUSINESSES MAY BE HARMED.

    Any new law or regulation pertaining to the Internet or the application or
interpretation of existing laws could decrease the demand for our Internet
businesses, increase the cost of doing business of About.com and our other new
media businesses or otherwise have a material adverse effect on our business,
results of operations and financial condition. There are and will be an
increasing number of laws and regulations pertaining to the Internet. These laws
or regulations may relate to liability for information retrieved from or
transmitted over the Internet, online content regulation, user privacy, taxation
and the quality of products and services. In addition, the applicability to the
Internet of existing laws governing intellectual property ownership and
infringement, copyright, trademark, trade secret, obscenity, libel, employment,
personal privacy and other issues is uncertain and developing.

                                       17
<Page>
   IN ORDER FOR OUR NEW MEDIA BUSINESSES TO SUCCEED, WE MUST RESPOND TO THE
   RAPID CHANGES IN TECHNOLOGY.

    The markets for Internet products and services are characterized by:

    - rapidly changing technology;

    - evolving industry standards;

    - frequent new product and service introductions; and

    - changing customer demands.

    The success of our new media businesses will depend on our ability to adapt
to this rapidly evolving marketplace. We may not be able to adequately adapt its
products and services or to acquire new products and services that can compete
successfully. In addition, we may not be able to establish and maintain
effective distribution channels.

   THE SUCCESS OF OUR NEW MEDIA BUSINESSES DEPENDS ON USE OF THE INTERNET BY
   BUSINESSES AND INDIVIDUALS.

    The success of our new media businesses depends on use of the Internet for
advertising, marketing, providing services and conducting business. Our new
media businesses may suffer if commercial use of the Internet fails to grow in
the future. Commercial use of the Internet is currently at an early stage of
development and the future of the Internet is not clear. Internet usage may be
inhibited for any of the following reasons:

    - the Internet infrastructure may not be able to support the demands placed
      on it, and its performance and reliability may decline as usage grows;

    - security and authentication concerns with respect to the transmission over
      the Internet of confidential information, such as credit card numbers, and
      attempts by unauthorized computer users, so-called hackers, to penetrate
      online security systems; and

    - privacy concerns, including those related to the ability of web sites to
      gather user information without the user's knowledge or consent.

    In addition, it is not clear how effective advertising on the Internet is in
generating business as compared to more traditional types of advertising such as
print, television and radio. The adoption of Internet advertising, particularly
by those entities that have historically relied upon traditional media for
advertising, requires the acceptance of a new way of conducting business,
exchanging information and advertising products and services. Advertisers that
have traditionally relied upon other advertising media may be reluctant to
advertise on the Internet. These businesses may find Internet advertising to be
less effective than traditional advertising media for promoting their products
and services.

   WE FACE SPECIFIC SECURITY RISKS REGARDING THE TRANSMISSION OF CONFIDENTIAL
   INFORMATION.

    Consumer concerns about the security of transmissions of confidential
information over public telecommunications facilities is a significant barrier
to electronic commerce and communications. Many factors may cause compromises or
breaches of our security systems or other Internet sites used to protect
proprietary information, including advances in computer and software
functionality or new discoveries in the field of cryptography. A compromise of
security on the Internet would have a negative effect on the use of the Internet
for commerce and communications and negatively impact our businesses. Security
breaches of our activities or the activities of our customers and sponsors
involving the storage and transmission of proprietary information, such as
credit card numbers, may expose us to a risk of loss or litigation and possible
liability. Our security measures designed to prevent security breaches and
insurance programs we obtain to address the potential losses or liabilities may
not be sufficient to cover any such losses or liabilities.

                                       18
<Page>
    WE MAY HAVE LIABILITY FOR INFORMATION RETRIEVED FROM THE INTERNET.

    Because materials may be downloaded from the Internet and subsequently
distributed to others, we may be subject to claims for defamation, negligence,
copyright or trademark infringement, personal injury or other theories based on
the nature, content, publication and distribution of those materials.

   WE MAY NOT BE ABLE TO PROTECT OUR INTELLECTUAL PROPERTY, AND WE MAY BE LIABLE
   FOR INFRINGING THE INTELLECTUAL PROPERTY OF OTHERS.

    Third parties may infringe or misappropriate our and our subsidiaries'
patents, trademarks or other intellectual property, which could have a material
adverse effect on our business, results of operations or financial condition.
While we and our subsidiaries enter into confidentiality agreements with our
material employees, guides, consultants and strategic partners, and generally
control access to and distribution of our proprietary information, the steps we
and our subsidiaries have taken to protect our intellectual property may not
prevent misappropriation. In addition, we and our subsidiaries do not know
whether we will be able to defend our proprietary rights since the validity,
enforceability and scope of protection of proprietary rights in Internet-related
industries is still evolving.

    Third parties may assert infringement claims against us or our subsidiaries.
From time to time in the ordinary course of business we and our subsidiaries
have been, and we expect to continue to be, subject to claims of alleged
infringement of the trademarks and other intellectual property rights of third
parties. These claims and any resultant litigation, should it occur, could
subject us and our subsidiaries to significant liability for damages. In
addition, even if we and our subsidiaries prevail, litigation could be
time-consuming and expensive to defend and could result in the diversion of our
time and attention. Any claims from third parties may also result in limitations
on our and our subsidiaries' ability to use the intellectual property subject to
these claims unless we are able to enter into agreements with the third parties
making these claims.

                  RISK FACTORS RELATING TO THE EXCHANGE OFFER

    IF YOU FAIL TO TENDER YOUR OLD NOTES IN THE EXCHANGE OFFER, THEN THE
    LIQUIDITY OF THE MARKET FOR YOUR NOTES MAY BE SUBSTANTIALLY LIMITED.

    We expect that a substantial portion of the old notes will be tendered and
accepted in the exchange offer and exchanged for new notes. When the exchange
offer is completed, the amount of old notes will be reduced by the amount of new
notes that we will issue. Accordingly, we expect that the liquidity of the
market for the old notes after the exchange offer is completed will be
substantially limited.

    IF YOU FAIL TO EXCHANGE YOUR OLD NOTES IN THE EXCHANGE OFFER, YOUR OLD NOTES
    WILL CONTINUE TO BE SUBJECT TO TRANSFER RESTRICTIONS.

    If you do not exchange your old notes for new notes in the exchange offer
your old notes will continue to be subject to the transfer restrictions outlined
in the offering memorandum distributed in connection with the offering of the
old notes. In general, the old notes may not be offered or sold unless they are
registered or exempt from registration under the Securities Act and applicable
state securities laws. Except as required by the registration rights agreements,
we do not intend to register resales of the old notes under the Securities Act.

                                       19
<Page>
                     RISK FACTORS RELATING TO THE NEW NOTES

    WE ARE A HOLDING COMPANY AND OUR ABILITY TO MEET INTEREST AND PRINCIPAL
    PAYMENTS DEPENDS UPON DISTRIBUTIONS FROM OUR SUBSIDIARIES.

    We are a holding company and conduct all of our operations through our
subsidiaries and currently have no significant operating assets other than our
investments in our operating subsidiaries. As a result, we must rely on
dividends and other advances and transfers of funds from our subsidiaries to
meet our debt service and other obligations. The ability of our subsidiaries to
pay dividends or make other advances and transfers of funds will depend on their
respective operating results and may be restricted by, among other things, the
laws of their jurisdiction of organization which limit the amount of funds
available for the payment of dividends and agreements of those subsidiaries.
Although the indenture will limit the ability of most of those subsidiaries to
enter into consensual restrictions on their ability to pay dividends or make
other advances and transfers of funds to us, those limitations are subject to a
number of significant qualifications and exceptions. Although most of our
subsidiaries will guarantee the new notes, some will not, and in any event these
guarantees may not be enforceable. See "--A court may be able to void the
guarantees of the new notes and require holders of the new notes to return
payments received from our subsidiaries."

    NOT ALL OF OUR SUBSIDIARIES GUARANTEE OUR OBLIGATIONS UNDER THE NEW NOTES,
    AND THE ASSETS OF THE NON-GUARANTOR SUBSIDIARIES MAY NOT BE AVAILABLE TO
    MAKE PAYMENTS ON THE NEW NOTES.

    Our present and future foreign subsidiaries and our partially owned domestic
subsidiaries will not be guarantors of the new notes. Our present and future
wholly-owned domestic subsidiaries will guarantee the new notes, except domestic
subsidiaries that engage only in the business of financing accounts receivable
or that may be designated as unrestricted with respect to the indenture.
Payments on the new notes are only required to be made by us and the subsidiary
guarantors. As a result, no payments are required to be made from assets of
subsidiaries that do not guarantee the new notes, unless those assets are
transferred by dividend or otherwise to us or a subsidiary guarantor.

    In the event of a bankruptcy, liquidation or reorganization of any of the
non-guarantor subsidiaries, holders of their indebtedness, including their trade
creditors, would generally be entitled to payment of their claims from the
assets of those subsidiaries before any assets are made available for
distribution to us. As a result, the new notes are effectively subordinated to
the indebtedness of the non-guarantor subsidiaries.

    For the year ended December 31, 2000 and for the six months ended June 30,
2001, our non-guarantor subsidiaries had net sales of $62.0 million and
$63.2 million, respectively. The non-guarantor subsidiaries historically have
had negative EBITDA but could turn profitable in the future.

    WE MAY NOT BE PERMITTED OR HAVE THE ABILITY TO PURCHASE THE NEW NOTES UPON A
    CHANGE OF CONTROL AS REQUIRED BY THE INDENTURE.

    Our ability to repurchase new notes in connection with a change of control
may be limited by a number of factors. The occurrence of certain events that
constitute a change of control would constitute a default under our bank credit
facilities and would require us to make an offer to purchase our other
outstanding notes. In that event, we must repay our borrowings under our bank
credit facilities and repurchase any new notes and any of our other outstanding
notes that are tendered for repurchase. We may also incur future indebtedness
that may require us to offer to repurchase that indebtedness upon a change of
control. We may not have sufficient funds to repay or repurchase all that
indebtedness. Our failure to repay outstanding indebtedness under our bank
credit facilities, make a change of control offer when required or to purchase
tendered notes when tendered would constitute

                                       20
<Page>
an event of default under the indenture related to the new notes and the
indentures governing our other outstanding notes.

    In addition, certain events that may constitute a change of control under
our bank credit facilities and cause us to be required to repay our borrowings
under the bank credit facilities may not constitute a change of control under
the indenture related to the new notes. In that case, we may not have sufficient
funds to repurchase that indebtedness, which would cause us to be in default
under the bank credit facilities, the new notes and all our outstanding notes.
Our and our subsidiaries' future indebtedness may also contain prohibitions of
certain events that would constitute a change of control or require indebtedness
to be repurchased upon a change of control.

    A COURT MAY BE ABLE TO VOID THE GUARANTEES OF THE NEW NOTES AND REQUIRE
    HOLDERS OF THE NEW NOTES TO RETURN PAYMENTS RECEIVED FROM OUR SUBSIDIARIES.

    Under federal bankruptcy law and comparable provisions of state fraudulent
transfer laws, a guarantee could be voided, or claims in respect of a guarantee
could be subordinated to all other debts of the guarantor if, among other
things, the subsidiary guarantor, at the time that the subsidiary guarantor
issued the guarantee:

    - issued the guarantee to delay, hinder or defraud present or future
      creditors; or

    - received less than reasonably equivalent value or fair consideration for
      issuing the guarantee and at the time it issued the guarantee:

       - was insolvent or rendered insolvent by reason of issuing the guarantee
         and the application of the proceeds of the guarantee;

       - was engaged or about to engage in a business or transaction for which
         the guarantor's remaining unencumbered assets constituted unreasonably
         small capital to carry on its business;

       - intended to incur, or believed that it would incur, debts beyond its
         ability to pay the debts as they mature; or

       - it was a defendant in an action for money damages, or had a judgment
         for money damages docketed against it if, in either case, after final
         judgment, the judgment is unsatisfied.

    In addition, any payment by the guarantor under its guarantee could be
voided and required to be returned to the guarantor or to a fund for the benefit
of the creditors of the guarantor or the guarantee could be subordinated to
other debt of the subsidiary guarantor.

    The measures of insolvency for purposes of fraudulent transfer laws vary
depending upon the law applied in any proceeding to determine whether a
fraudulent transfer has occurred. Generally, however, a person would be
considered insolvent if, at the time it incurred the debt:

    - the present fair saleable value of its assets was less than the amount
      that would be required to pay its probable liability on its existing
      debts, including contingent liabilities, as they become absolute and
      mature; or

    - it could not pay its debts as they become due.

    We cannot be sure as to the standard that a court would use to determine
whether or not the guarantor subsidiaries were solvent at the relevant time, or,
regardless of the standard that the court uses, that the issuance of the
guarantee of the notes would not be voided or the guarantee of the notes would
not be subordinated to that subsidiary guarantor's other debt.

    If such a case were to occur, any guarantee of the new notes incurred by one
of the subsidiary guarantors could also be subject to the claim that, since the
guarantee was incurred for our benefit, and

                                       21
<Page>
only indirectly for the benefit of the subsidiary guarantor, the obligations of
the applicable guarantor were incurred for less than fair consideration. A court
could therefore void the obligations under the guarantees or subordinate the
guarantees to the applicable guarantor's other debt or take action detrimental
to holders of the notes.

                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

    We have entered into a registration rights agreement with the initial
purchasers of the old notes in which we and our subsidiaries agreed, under some
circumstances, to file a registration statement relating to an offer to exchange
the old notes for new notes. We and some of our subsidiaries also agreed to use
our reasonable best efforts to cause the offer to be consummated within 230 days
following the original issue of the old notes. The new notes will have terms
substantially identical to the old notes, except that the new notes will not
contain terms with respect to transfer restrictions, registration rights and
liquidated damages for failure to observe some obligations in the registration
rights agreement. The old notes were issued on May 8, 2001.

    Under the circumstances set forth below, we will use our reasonable best
efforts to cause the SEC to declare effective a shelf registration statement
with respect to the resale of the old notes and keep the statement effective for
up to two years after the effective date of the shelf registration statement.
These circumstances include if:

           (a)  we are not required to file the exchange offer registration
                statement or permitted to consummate the exchange offer because
                the exchange offer is not permitted by applicable law or SEC
                policy; or

           (b)  any holder of old notes notifies us prior to the 20th day
                following consummation of the exchange offer that:

               (1)  it is prohibited by law or SEC policy from participating in
                    the exchange offer; or

               (2)  it may not resell the new notes acquired by it in the
                    exchange offer to the public without delivering a prospectus
                    and the prospectus contained in the exchange offer
                    registration statement is not available for such resales; or

               (3)  it is a broker-dealer and owns old notes acquired directly
                    from us or an affiliate of ours.

    If we fail to comply with some obligations under the registration rights
agreement, we will be required to pay liquidated damages to each holder of old
notes. See "Description of New Notes--Exchange Offer; Registration Rights."

    Each holder of old notes that wishes to exchange old notes for transferable
new notes in the exchange offer will be required to make the following
representations:

    - any new notes will be acquired in the ordinary course of its business;

    - the holder has no arrangement with any person to participate in the
      distribution of the new notes;

    - the holder is not an "affiliate," as defined in Rule 405 of the Securities
      Act, of ours or if it is an affiliate, that it will comply with applicable
      registration and prospectus delivery requirements of the Securities Act;

    - if the holder is not a broker-dealer, that it is not engaged in, and does
      not intend to engage in, the distribution of the new notes; and

    - if the holder is a broker-dealer, that it will receive new notes for its
      own account in exchange for old notes that were acquired as a result of
      market-making activities or other trading activities and that it will be
      required to acknowledge that it will deliver a prospectus in connection
      with any resale of the new notes. See "Plan of Distribution."

                                       23
<Page>
RESALE OF EXCHANGE NOTES

    Based on interpretations of the SEC staff outlined in no action letters
issued to unrelated third parties, we believe that new notes issued under the
exchange offer in exchange for old notes may be offered for resale, resold and
otherwise transferred by any new note holder without compliance with the
registration and prospectus delivery provisions of the Securities Act, if:

    - the holder is not an "affiliate" of ours within the meaning of Rule 405
      under the Securities Act;

    - the new notes are acquired in the ordinary course of the holder's
      business; and

    - the holder does not intend to participate in the distribution of the new
      notes.

    Any holder who tenders in the exchange offer with the intention of
participating in any manner in a distribution of the new notes:

    - cannot rely on the position of the staff of the SEC enunciated in EXXON
      CAPITAL HOLDINGS CORPORATION or similar interpretive letters; and

    - must comply with the registration and prospectus delivery requirements of
      the Securities Act in connection with a secondary resale transaction.

    This prospectus may be used for an offer to resell, for the resale or for
other retransfer of new notes only as specifically set forth in this prospectus.
With regard to broker-dealers, only broker-dealers that acquired the old notes
as a result of market-making activities or other trading activities may
participate in the exchange offer. Each broker-dealer that receives new notes
for its own account in exchange for old notes, where the old notes were acquired
by the broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of the new notes. Please read the section captioned "Plan of
Distribution" for more details regarding the transfer of new notes.

TERMS OF THE EXCHANGE OFFER

    Upon the terms and subject to the conditions included in this prospectus and
in the accompanying letter of transmittal, we will accept for exchange any old
notes properly tendered and not withdrawn prior to the expiration date. We will
issue $1,000 principal amount of new notes in exchange for each $1,000 principal
amount of old notes surrendered under the exchange offer. Old notes may be
tendered only in integral multiples of $1,000.

    The form and terms of the new notes will be substantially identical to the
form and terms of the old notes except the new notes will be registered under
the Securities Act, will not bear legends restricting their transfer and will
not provide for any liquidated damages upon our failure to fulfill our
obligations under the registration rights agreement to file, and cause to be
effective, a registration statement. The new notes will evidence the same debt
as old notes. The new notes will be issued under and entitled to the benefits of
the same indenture that authorized the issuance of the old notes.

    The exchange offer is not conditioned upon any minimum aggregate principal
amount of old notes being tendered for exchange.

    As of the date of this prospectus, $500.0 million aggregate principal amount
of the old notes are outstanding. This prospectus and a letter of transmittal
are being sent to all registered holders of old notes. There will be no fixed
record date for determining registered holders of old notes entitled to
participate in the exchange offer.

    We intend to conduct the exchange offer in accordance with the provisions of
the registration rights agreement, the applicable requirements of the Securities
Act and the Exchange Act and the rules and regulations of the SEC. Old notes
that are not tendered for exchange in the exchange offer

                                       24
<Page>
will remain outstanding and continue to accrue interest and will be entitled to
the rights and benefits the holders have under the indenture relating to the old
notes, except for any rights under the registration rights agreement that by
their terms terminate upon the consummation of the exchange offer.

    We will be deemed to have accepted for exchange properly tendered old notes
when we have given oral or written notice of the acceptance to the exchange
agent. The exchange agent will act as agent for the tendering holders for the
purposes of receiving the new notes from us and delivering new notes to the
holders. Under the terms of the registration rights agreement, we reserve the
right to amend or terminate the exchange offer, and not to accept for exchange
any old notes not previously accepted for exchange, upon the occurrence of any
of the conditions specified below under the caption "--Material Conditions to
the Exchange Offer."

    Holders who tender old notes in the exchange offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the letter
of transmittal, transfer taxes with respect to the exchange of old notes. We
will pay all charges and expenses, other than certain applicable taxes described
below, in connection with the exchange offer. It is important that you read the
section labeled "--Fees and Expenses" below for more details regarding fees and
expenses incurred in the exchange offer.

EXPIRATION DATE; EXTENSIONS; AMENDMENTS

    The exchange offer will expire at 5:00 p.m., New York City time on
          , 2001, unless in our sole discretion we extend it.

    In order to extend the exchange offer, we will notify the exchange agent
orally or in writing of any extension. We will notify the registered holders of
old notes of the extension no later than 9:00 a.m., New York City time, on the
business day after the previously scheduled expiration date.

    We reserve the right, in our sole discretion:

    - to delay accepting for exchange any old notes;

    - to extend the exchange offer or to terminate the exchange offer and to
      refuse to accept old notes not previously accepted if any of the
      conditions set forth below under "--Material Conditions to the Exchange
      Offer" have not been satisfied, by giving oral or written notice of such
      delay, extension or termination to the exchange agent; or

    - under the terms of the registration rights agreement, to amend the terms
      of the exchange offer in any manner.

    Any delay in acceptance, extension, termination, or amendment will be
followed as promptly as practicable by oral or written notice to the registered
holders of old notes. If we amend the exchange offer in a manner that we
determine constitutes a material change, we will promptly disclose the amendment
in a manner reasonably calculated to inform the holder of old notes of the
amendment.

    Without limiting the manner in which we may choose to make public
announcements of any delay in acceptance, extension, termination or amendment of
the exchange offer, we will have no obligation to publish, advertise, or
otherwise communicate any public announcement, other than by making a timely
release to a financial news service.

MATERIAL CONDITIONS TO THE EXCHANGE OFFER

    Despite any other term of the exchange offer, we will not be required to
accept for exchange, or exchange any new notes for, any old notes, and we may
terminate the exchange offer as provided in this prospectus before accepting any
old notes for exchange if in our reasonable judgment:

                                       25
<Page>
    - the new notes to be received will not be tradable by the holder, without
      restriction under the Securities Act, the Exchange Act and without
      material restrictions under the blue sky or securities laws of
      substantially all of the states of the United States;

    - the exchange offer, or the making of any exchange by a holder of old
      notes, would violate applicable law or any applicable interpretation of
      the staff of the SEC; or

    - any action or proceeding has been instituted or threatened in any court or
      by or before any governmental agency with respect to the exchange offer
      that, in our judgment, would reasonably be expected to impair our ability
      to proceed with the exchange offer.

    In addition, we will not be obligated to accept for exchange the old notes
of any holder that has not made to us:

    - the representations described under "Purpose and Effect of the Exchange
      Offer," "--Procedures for Tendering" and "Plan of Distribution"; and

    - other representations as may be reasonably necessary under applicable SEC
      rules, regulations or interpretations to make available to it an
      appropriate form for registration of the new notes under the Securities
      Act.

    We expressly reserve the right, at any time or at various times, to extend
the period of time during which the exchange offer is open. Consequently, we may
delay acceptance of any old notes by giving oral or written notice of the
extension to their holders. During any extensions, all old notes previously
tendered will remain subject to the exchange offer, and we may accept them for
exchange. We will return any old notes that we do not accept for exchange for
any reason without expense to their tendering holder as promptly as practicable
after the expiration or termination of the exchange offer.

    We expressly reserve the right to amend or terminate the exchange offer, and
to reject for exchange any old notes not previously accepted for exchange, upon
the occurrence of any of the conditions of the exchange offer specified above.
We will give oral or written notice of any extension, amendment, non-acceptance,
or termination to the holders of the old notes as promptly as practicable.

    Those conditions are for our sole benefit and we may assert them regardless
of the circumstances that may give rise to them or waive them in whole or in
part at any or at various times in our sole discretion. If we fail at any time
to exercise any of these rights, this failure will not constitute a waiver of
this right. Each right will be deemed an ongoing right that we may assert at any
time or at various times.

    In addition, we will not accept for exchange any old notes tendered, and
will not issue new notes in exchange for any old notes, if at the time any stop
order will be threatened or in effect with respect to the registration statement
of which this prospectus constitutes a part or the qualification of the
indenture under the Trust Indenture Act.

PROCEDURES FOR TENDERING

    Only a holder of old notes may tender the old notes in the exchange offer.
To tender in the exchange offer, a holder must:

    - complete, sign and date the accompanying letter of transmittal, or a
      facsimile of the letter of transmittal; have the signature on the letter
      of transmittal guaranteed if the letter of transmittal so requires; and
      mail or deliver the letter of transmittal or facsimile to the exchange
      agent prior to the expiration date; or

    - comply with the DTC's Automated Tender Offer Program procedures described
      below.

    In addition, either:

                                       26
<Page>
    - the exchange agent must receive the old notes along with the accompanying
      letter of transmittal; or

    - the exchange agent must receive, prior to the expiration date, a timely
      confirmation of book-entry transfer of the old notes into the exchange
      agent's account at the DTC according to the procedures for book-entry
      transfer described below or a properly transmitted agent's message; or

    - the holder must comply with the guaranteed delivery procedures described
      below.

    To be tendered effectively, the exchange agent must receive any physical
delivery of a letter of transmittal and other required documents at the address
set forth below under "--Exchange Agent" prior to the expiration date.

    The tender by a holder of old notes that is not withdrawn prior to the
expiration date will constitute an agreement between the holder of old notes and
us in accordance with the terms and subject to the conditions set forth in this
prospectus and in the accompanying letter of transmittal.

    The method of delivery of old notes, the letter of transmittal and all other
required documents to the exchange agent is at the holder's election and risk.
Rather than mail these items, we recommend that holders use an overnight or hand
delivery service. In all cases, holders should allow sufficient time to assure
delivery to the exchange agent before the expiration date. Holders should not
send the letter of transmittal or old notes to us. Holders may request their
respective brokers, dealers, commercial banks, trust companies or other nominees
to effect the above transactions for them.

    Any beneficial owner whose old notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to tender
should contact the registered holder promptly and instruct it to tender on the
owners' behalf. If the beneficial owner wishes to tender on its own behalf, it
must, prior to completing and executing the accompanying letter of transmittal
and delivering its old notes either:

    - make appropriate arrangements to register ownership of the old notes in
      such owner's name; or

    - obtain a properly completed bond power from the registered holder of old
      notes.

    The transfer of registered ownership may take considerable time and may not
be completed prior to the expiration date.

    Signatures on a letter of transmittal or a notice of withdrawal described
below must be guaranteed by a member firm of a registered national securities
exchange or of the National Association of Securities Dealers, Inc., a
commercial bank or trust company having an office or correspondent in the United
States or another "eligible institution" within the meaning of Rule 17Ad-15
under the Exchange Act, unless the old notes are tendered:

    - by a registered holder who has not completed the box entitled "Special
      Issuance Instructions" or "Special Delivery Instructions" on the
      accompanying letter of transmittal; or

    - for the account of an eligible institution.

    If the accompanying letter of transmittal is signed by a person other than
the registered holder of any old notes listed on the old notes, the old notes
must be endorsed or accompanied by a properly completed bond power. The bond
power must be signed by the registered holder as the registered holder's name
appears on the old notes and an eligible institution must guarantee the
signature on the bond power.

    If the accompanying letter of transmittal or any old notes or bond powers
are signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, these persons should so indicate when signing. Unless waived by us,
they should also submit evidence satisfactory to us of their authority to
deliver the accompanying letter of transmittal.

                                       27
<Page>
    The exchange agent and the DTC have confirmed that any financial institution
that is a participant in the DTC's system may use the DTC's Automated Tender
Offer program to tender. Participants in the program may, instead of physically
completing and signing the accompanying letter of transmittal and delivering it
to the exchange agent, transmit their acceptance of the exchange offer
electronically. They may do so by causing the DTC to transfer the old notes to
the exchange agent in accordance with its procedures for transfer. The DTC will
then send an agent's message to the exchange agent. The term "agent's message"
means a message transmitted by the DTC, received by the exchange agent and
forming part of the book-entry confirmation, to the effect that:

    - the DTC has received an express acknowledgment from a participant in its
      Automated Tender Offer Program that is tendering old notes that are the
      subject of the book-entry confirmation;

    - the participant has received and agrees to be bound by the terms of the
      accompanying letter of transmittal, or, in the case of an agent's message
      relating to guaranteed delivery, that the participant has received and
      agrees to be bound by the applicable notice of guaranteed delivery; and

    - the agreement may be enforced against that participant.

    We will determine in our sole discretion all outstanding questions as to the
validity, form, eligibility, including time or receipt, acceptance of tendered
old notes and withdrawal of tendered old notes. Our determination will be final
and binding. We reserve the absolute right to reject any old notes not properly
tendered or any old notes the acceptance of which would, in the opinion of our
counsel, be unlawful. We also reserve the right to waive any defects,
irregularities or conditions of tender as to particular old notes. Our
interpretation of the terms and conditions of the exchange offer, including the
instructions in the accompanying letter of transmittal, will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of old notes must be cured within the time as we will
determine. Although we intend to notify holders of defects or irregularities
with respect to tenders of old notes, neither we, the exchange agent nor any
other person will incur any liability for failure to give any notification.
Tenders of old notes will not be deemed made until any defects or irregularities
have been cured or waived. Any old notes received by the exchange agent that are
not properly tendered and as to which the defects or irregularities have not
been cured or waived will be returned to the exchange agent without cost to the
tendering holder, unless otherwise provided in the letter of transmittal, as
soon as practicable following the expiration date.

    In all cases, we will issue new notes for old notes that we have accepted
for exchange under the exchange offer only after the exchange agent timely
receives:

    - old notes or a timely book-entry confirmation of the old notes into the
      exchange agent's account at the DTC; and

    - a properly completed and duly executed letter of transmittal and all other
      required documents or a properly transmitted agent's message.

    By signing the accompanying letter of transmittal or authorizing the
transmission of the agent's message, each tendering holder of old notes will
represent or be deemed to have represented to us that, among other things:

    - any new notes that the holder receives will be acquired in the ordinary
      course of its business;

    - the holder has no arrangement or understanding with any person or entity
      to participate in the distribution of the new notes;

    - if the holder is not a broker-dealer, that is not engaged in and does not
      intend to engage in the distribution of the new notes;

                                       28
<Page>
    - if the holder is a broker-dealer that will receive new notes for its own
      account in exchange for old notes that were acquired as a result of
      market-making activities, that it will deliver a prospectus, as required
      by law, in connection with any resale of any new notes; and

    - the holder is not an "affiliate," as defined in Rule 405 of the Securities
      Act, of ours or, if the holder is an affiliate, it will comply with any
      applicable registration and prospectus delivery requirements of the
      Securities Act.

BOOK-ENTRY TRANSFER

    The exchange agent will make a request to establish an account with respect
to the old notes at the DTC for purposes of the exchange offer promptly after
the date of this prospectus. Any financial institution participating in the
DTC's system may make book-entry delivery of old notes by causing the DTC to
transfer the old notes into the exchange agent's account at the DTC in
accordance with the DTC's procedures for transfer. Holders of old notes who are
unable to deliver confirmation of the book-entry tender of their old notes into
the exchange agent's account at the DTC or all other documents required by the
letter of transmittal to the exchange agent on or prior to the expiration date
must tender their old notes according to the guaranteed delivery procedures
described below.

GUARANTEED DELIVERY PROCEDURES

    Holders wishing to tender their old notes but whose old notes are not
immediately available or who cannot deliver their old notes, the accompanying
letter of transmittal or any other required documents to the exchange agent or
comply with the applicable procedures under the DTC's Automated Tender Offer
Program prior to the expiration date may tender if:

    - the tender is made through an eligible institution;

    - prior to the expiration date, the exchange agent receives from the
      eligible institution either a properly completed and duly executed notice
      of guaranteed delivery, by facsimile transmission, mail or hand delivery,
      or a properly transmitted agent's message and notice of guaranteed
      delivery:

       - setting forth the name and address of the holder, the registered
         number(s) of the old notes and the principal amount of old notes
         tendered;

       - stating that the tender is being made thereby; and

       - guaranteeing that, within three New York Stock Exchange trading days
         after the expiration date, the accompanying letter of transmittal, or
         facsimile of the letter of transmittal, together with the old notes or
         a book-entry confirmation, and any other documents required by the
         accompanying letter of transmittal will be deposited by the eligible
         institution with the exchange agent; and

    - the exchange agent receives the properly completed and executed letter of
      transmittal, or facsimile of the executed letter of transmittal, as well
      as all tendered old notes in proper form for transfer or a book-entry
      confirmation, and all other documents required by the accompanying letter
      of transmittal, within three New York Stock Exchange trading days after
      the expiration date.

    Upon request to the exchange agent, a notice of guaranteed delivery will be
sent to holders who wish to tender their old notes according to the guaranteed
delivery procedures set forth above.

WITHDRAWAL OF TENDERS

    Except as otherwise provided in this prospectus, holders of old notes may
withdraw their tenders at any time prior to the expiration date.

                                       29
<Page>
    For a withdrawal to the effective:

    - the exchange agent must receive a written notice of withdrawal, which
      notice may be by telegram, telex, facsimile transmission or letter of
      withdrawal at one of the addresses set forth below under "--Exchange
      Agent"; or

    - holders must comply with the appropriate procedures of the DTC's Automated
      Tender Offer Program system.

    Any notice of withdrawal must:

    - specify the name of the person who tendered the old notes to be withdrawn;

    - identify the old notes to be withdrawn, including the principal amount of
      the old notes; and

    - where certificates for old notes have been transmitted, specify the name
      in which the old notes were registered, if different from that of the
      withdrawing holder.

    If certificates for old notes have been delivered or otherwise identified to
the exchange agent, then, prior to the release of the certificates, the
withdrawing holder must also submit:

    - the serial numbers of the particular certificates to be withdrawn; and

    - a signed notice of withdrawal with signatures guaranteed by an eligible
      institution unless the holder is an eligible institution.

    If old notes have been tendered pursuant to the procedure for book-entry
transfer described above, any notice of withdrawal must specify the name and
number of the account at the DTC to be credited with the withdrawn old notes and
otherwise comply with the procedures of that facility. We will determine all
questions as to the validity, form and eligibility, including time of receipt,
of the notices, and our determination will be final and binding on all parties.
We will deem any old notes so withdrawn not to have validly tendered for
exchange for purposes of the exchange offer. Any old notes that have been
tendered for exchange but that are not exchanged for any reason will be returned
to their holder without cost to the holder, or, in the case of old notes
tendered by book-entry transfer into the exchange agent's account at the DTC
according to the procedures described above, the old notes will be credited to
an account maintained with the DTC for old notes, as soon as practicable after
withdrawal, rejection of tender or termination of the exchange offer. Properly
withdrawn, old notes may be retendered by following one of the procedures
described under "--Procedures for Tendering" above at any time on or prior to
the expiration date.

    DELIVERY OF THE LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET FORTH
ABOVE OR TRANSMISSION VIA FACSIMILE OTHER THAN AS SET FORTH ABOVE DOES NOT
CONSTITUTE A VALID DELIVERY OF THE LETTER OF TRANSMITTAL.

FEES AND EXPENSES

    We will bear the expenses of soliciting tenders. The principal solicitation
is being made by mail; however, we may make additional solicitations by
telephone or in person by our officers and regular employees and those of our
affiliates.

    We have not retained any dealer-manager in connection with the exchange
offer and will not make any payments to broker-dealers or others soliciting
acceptance of the exchange offer. We will, however, pay the exchange agent
reasonable and customary fees for its services and reimburse it for its related
reasonable out-of-pocket expenses.

    We will pay the cash expenses to be incurred in connection with the exchange
offer. The expenses are estimated in the aggregate to be approximately $500,000.
They include:

    - SEC registration fees;

    - fees and expenses of the exchange agent and trustee;

    - accounting and legal fees and printing costs; and

    - related fees and expenses.

TRANSFER TAXES

    We will pay all transfer taxes, if any, applicable to the exchange of old
notes under the exchange offer. The tendering holder, however, will be required
to pay any transfer taxes, whether imposed on the registered holder or any other
person, if:

    - certificates representing old notes for principal amounts not tendered or
      accepted for exchange are to be delivered to, or are to be issued in the
      name of, any person other than the registered holder of old notes
      tendered;

    - tendered old notes are registered in the name of any person other than the
      person signing the letter of transmittal; or

                                       31
<Page>
    - a transfer tax is imposed for any reason other than the exchange of old
      notes under the exchange offer.

    If satisfactory evidence of payment of the taxes is not submitted with the
letter of transmittal, the amount of the transfer taxes will be billed to that
tendering holder.

    Holders who tender their old notes for exchange will not be required to pay
any transfer taxes. However, holders who instruct us to register new notes in
the name of, or request that old notes not tendered or not accepted in the
exchange offer be returned to, a person other than the registered tendering
holder will be required to pay any applicable transfer tax.

CONSEQUENCES OF FAILURE TO EXCHANGE

    Holders of old notes who do not exchange their old notes for new notes under
the exchange offer will remain subject to the restrictions on transfer of the
old notes:

    - as set forth in the legend printed on the old notes as a consequence of
      the issuance of the old notes under the exemption from, or in transactions
      not subject to, the registration requirements of the Securities Act and
      applicable state securities laws; and

    - otherwise as set forth in the prospectus distributed in connection with
      the private offering of the old notes.

    In general, you may not offer or sell the old notes unless they are
registered under the Securities Act, or if the offer or sale is exempt from
registration under the Securities Act and applicable state securities laws.
Except as required by the registration rights agreement, we do not intend to
register resales of the old notes under the Securities Act. Based on
interpretations of the SEC staff, new notes issued under the exchange offer may
be offered for resale, resold or otherwise transferred by their holders (other
than any holder that is our "affiliate" within the meaning of Rule 405 under the
Securities Act) without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that the holders acquired the new
notes in the ordinary course of the holders' business and the holders have no
arrangement or understanding with respect to the distribution of the new notes
to be acquired in the exchange offer. Any holder who tenders in the exchange
offer for the purpose of participating in a distribution of the new notes:

    - cannot rely on the applicable interpretations of the SEC; and

    - must comply with the registration and prospectus delivery requirements of
      the Securities Act in connection with a secondary resale transaction.

ACCOUNTING TREATMENT

    We will record the new notes in our accounting records at the same carrying
value as the old notes, which is the aggregate principal amount net of issuance
discount, as reflected in our accounting records on the date of exchange.
Accordingly, we will not recognize any gain or loss for accounting purposes in
connection with the exchange offer. The expenses of the exchange offer will be
deferred and amortized over the term of the related notes.

OTHER

    Participation in the exchange offer is voluntary, and you should carefully
consider whether to accept. You are urged to consult your financial and tax
advisors in making your own decision on what action to take.

    We may in the future seek to acquire untendered old notes in open market or
privately negotiated transactions, through subsequent exchange offers or
otherwise. We have no present plans to acquire any old notes that are not
tendered in the exchange offer or to file a registration statement to permit
resales of any untendered old notes.

                DESCRIPTION OF INDEBTEDNESS AND PREFERRED STOCK

BANK CREDIT FACILITIES

    On June 20, 2001, we completed a refinancing of our existing bank credit
facilities pursuant to new bank credit facilities with The Chase Manhattan Bank,
Bank of America, N.A, The Bank of New York and The Bank of Nova Scotia, as
agents. Borrowings under the bank credit facilities are guaranteed by each of
our wholly owned domestic restricted subsidiaries. The guarantees are full,
unconditional and joint and several. Certain of our subsidiaries, which
primarily represent Internet assets and businesses, including About.com, as well
as our foreign and securitization subsidiaries, are not guarantors of the bank
credit facilities.

    The borrowings under the bank credit facilities may be used for general
corporate and working capital purposes as well as to finance certain future
acquisitions. The bank credit facilities consist of the following:

    - a $475.0 million revolving loan facility, of which $33.0 million was
      outstanding at June 30, 2001;

    - a term loan A, of which $100.0 million was outstanding at June 30, 2001;
      and

    - a term loan B, of which $425.0 million was outstanding at June 30, 2001.

    As of June 30, 2001, we had $558.0 million borrowings outstanding,
$22.0 million letters of credit outstanding and unused bank commitments of
approximately $420.4 million under our bank credit facilities. We intend to draw
on our revolving loan facility in an amount of $270 million to partially finance
our acquisition of EMAP USA.

    With the exception of the term loan B, the amounts borrowed bear interest,
at our option, at either the higher of the base rate plus an applicable margin
ranging from 0.125% to 1.50% or the Eurodollar Rate plus an applicable margin
ranging from 1.125% to 2.50%. Additionally, until we issue financial statements
for the period ending December 31, 2001, the applicable margin for the amounts
borrowed will be a minimum of 0.75% for the base rate option and 1.75% for the
Eurodollar rate option. The term loan B bears interest at the base rate plus
1.75% or LIBOR plus 2.75%. At June 30, 2001, the weighted average variable
interest rate on all outstanding borrowings under the bank credit facilities was
6.46%.

    Under the bank credit facilities, we have agreed to pay commitment fees at a
per annum rate of either 0.375% or 0.50%, depending on our debt to EBITDA ratio
as defined in our new credit agreement, on the daily average aggregate
unutilized commitment under the revolving loan commitment. We also have agreed
to pay certain fees with respect to the issuance of letters of credit and an
annual administration fee.

    The commitments under the revolving loan commitment are subject to mandatory
reductions semiannually on June 30 and December 31 commencing December 31, 2004
with the final reduction on June 30, 2008. The aggregate mandatory reductions of
the revolving loan commitments under the bank credit facility are
$23.75 million in 2004, $47.5 million in 2005, $71.25 million in 2006,
$142.5 million in 2007 and a final reduction of $190.0 million in 2008. To the
extent that the total revolving credit loans outstanding exceed the reduced
commitment amount, these loans must be paid down to an amount equal to or less
than the reduced commitment amount. However, if the total revolving credit loans
outstanding do not exceed the reduced commitment amount, then there is no
requirement to pay down any of the revolving credit loans. Aggregate term loan
payments under the bank credit facility are $2.125 million in 2001,
$4.25 million in 2002 and 2003, $16.75 million in 2004, $29.25 million in 2005,
2006 and 2007, $16.75 million in 2008 and $393.125 million in 2009.

    The bank credit facilities, among other things, limit our ability to change
the nature of our businesses, incur indebtedness, create liens, sell assets,
engage in mergers, consolidations or transactions

                                       33
<Page>
with affiliates, make investments in or loans to certain subsidiaries, issue
guarantees and make certain restricted payments including dividend payments on
our common stock in excess of $75.0 million in any given year. Under our most
restrictive debt covenants, we must maintain a minimum interest coverage ratio
of 1.80 to 1 and a minimum fixed charge coverage ratio of 1.05 to 1. Our maximum
allowable debt leverage ratio is 6.0 to 1. The maximum leverage ratio decreases
to 5.75 to 1, 5.5 to 1, 5.0 to 1 and 4.5 to 1, respectively, on July 1, 2003,
January 1, 2004, January 1, 2005 and January 1, 2006. The minimum interest
coverage ratio increases to 2.0 to 1, 2.25 to 1 and 2.5 to 1, respectively, on
July 1, 2003, January 1, 2004 and January 1, 2005.

    The bank credit facilities required us to create a new intermediate holding
company to own, directly or indirectly, our restricted subsidiaries. We pledged
the stock of this new intermediate holding company to secure our obligations
under the bank credit facilities and our outstanding notes.

    As a result of the refinancing of our existing bank credit facilities, we
wrote-off the remaining balance of deferred financing costs originally recorded.

    If we become subject to a change of control, each holder of the notes will

$10.00 SERIES D EXCHANGEABLE PREFERRED STOCK

    In 1996, we completed an offering of 2,000,000 shares of $0.01 par value,
Series D preferred stock at $100 per share. Annual dividends of $10 per share on
the Series D preferred stock are cumulative and payable quarterly in cash. The
liquidation and redemption value is $200 million. On or after February 1, 2001,
the Series D preferred stock may be redeemed in whole or in part, at our option,
at specified redemption prices plus accrued and unpaid dividends. We are

quarterly in cash. We are required to redeem the Series F exchangeable preferred
stock on November 1, 2009 at a redemption price equal to the liquidation

SERIES J CONVERTIBLE PREFERRED STOCK

    To partially finance our acquisition of EMAP USA, we intend to issue to KKR
or one of its affiliates shares of Series J convertible preferred stock, par
value $0.01 per share, with an aggregate liquidation preference of
$125 million. We expect annual dividends at a rate of 12.5% on the Series J
convertible preferred stock to be cumulative and payable quarterly in kind. We
expect the preferred stock to be perpetual and to rank PARI PASSU with our
existing series of outstanding preferred stock. We expect to have the option to
redeem any or all of the shares of preferred stock at any time for cash at 100%
of the liquidation preference of each share being redeemed. We also expect that
the preferred stock will be convertible into shares of our common stock at any
time after the first anniversary of the issue date at a conversion price of $7
per share, subject to adjustments. We also expect to have the option to cause at
any time the preferred stock to be exchanged into subordinated debt of ours. Our
ability to redeem or exchange the convertible preferred stock into debt will be
subject to the approval of a majority of our independent directors.

                            DESCRIPTION OF NEW NOTES

    THE FOLLOWING IS A SUMMARY DESCRIPTION OF THE NEW NOTES, WHICH WE REFER TO
IN THIS SECTION AS THE NOTES.

GENERAL

    PRIMEDIA will issue the notes under an indenture (the "Indenture") among
PRIMEDIA, the Guarantors and The Bank of New York, as trustee (the "Trustee").
The terms of the notes include those stated in the Indenture and those made part
of the Indenture by reference to the Trust Indenture Act of 1939, as amended.
The notes are subject to all those terms, and holders of the notes are referred
to the Indenture and the Trust Indenture Act for a statement of those terms. You
can find the definitions of certain terms used in the following description
under "--Certain Definitions."

    The notes:

    - are general obligations of PRIMEDIA;

    - rank PARI PASSU in right of payment with all existing and future senior
      indebtedness of PRIMEDIA, including PRIMEDIA's obligations under the
      Credit Facilities and the Outstanding Notes;

    - are senior in right of payment to any future subordinated indebtedness of
      PRIMEDIA;

    - are fully and unconditionally guaranteed on a senior basis by each
      domestic, wholly-owned Restricted Subsidiary of PRIMEDIA, other than any
      Securitization Subsidiary; and

    - are secured, together with all of PRIMEDIA's other senior indebtedness by
      a pledge of the stock of PRIMEDIA Companies Inc., an intermediate holding
      company owned directly by PRIMEDIA. PRIMEDIA Companies Inc. owns all of
      PRIMEDIA's operating subsidiaries.

    As of June 30, 2001, PRIMEDIA had approximately $1,698.9 million of senior
indebtedness, consisting of $558.0 million of borrowings under the Credit
Facilities, $100.0 million of PRIMEDIA's 10 1/4% senior notes due 2004,
$299.3 million of PRIMEDIA's 8 1/2% senior notes due 2006, $248.9 million in
aggregate principal amount of PRIMEDIA's 7 5/8% senior notes due 2008 and
$492.7 million of the old notes. In addition, as a result of the concurrent
transactions, PRIMEDIA expects to draw upon its revolving credit facility in an
amount of $270 million. The notes will rank PARI PASSU in right of payment with
all this indebtedness. As of June 30, 2001, PRIMEDIA had no subordinated
indebtedness outstanding. Subject to the financial covenants in the Credit
Facilities, PRIMEDIA has the option at any time to exchange its outstanding
series of preferred stock into subordinated indebtedness in an aggregate
principal amount of $562.1 million.

    The Guarantors have guaranteed PRIMEDIA's obligations under the Credit
Facilities and the Outstanding Notes. As of June 30, 2001, the Guarantors had on
a combined basis approximately $28.9 million of additional senior indebtedness,
all of which is secured by a pledge of the stock of PRIMEDIA Companies Inc. The
guarantees under the notes will rank PARI PASSU in right of payment with all of
the guarantees under the Credit Facilities and the Outstanding Notes.

PRINCIPAL, MATURITY, AND INTEREST

    The notes initially are limited in aggregate principal amount to
$500.0 million and will mature on May 15, 2011. The notes will be issued in
registered form, without coupons, in denominations of $1,000 and integral
multiples of $1,000. Additional notes may be issued from time to time after this
offering, subject to the provisions of the Indenture described below under the
caption "--Certain Covenants--Incurrence of Indebtedness." The new notes offered
under this prospectus, the old notes and any additional notes subsequently
issued would be treated as a single class for all purposes under the Indenture,
including, without limitation, waivers, amendments, redemptions and offers to
purchase. Unless the context otherwise requires, for all purposes of the
Indenture and this "Description of New

                                       37
<Page>
Notes," references to the notes include any additional notes actually issued.
Interest on the notes will accrue at the rate of 8 7/8% per annum and will be
payable semiannually on May 15 and November 15, commencing on November 15, 2001,
to holders of record on the immediately preceding May 1 and November 1.

    Interest on the notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from the original date
of issuance. Interest will be computed on the basis of a 360-day year consisting
of twelve 30-day months.

    We may be obligated to pay liquidated damages with respect to the old notes
in certain circumstances under the Registration Rights Agreement. See
"--Registration Rights; Liquidated Damages."

    The notes will be payable both as to principal and interest at the office or
agency of PRIMEDIA maintained for that purpose within or without the City and
State of New York or, at the option of PRIMEDIA, payment of interest may be made
by check mailed to the holders of the notes at their respective addresses set
forth in the register of holders of notes. Until otherwise designated by
PRIMEDIA, its office or agency in New York will be the office of the Trustee
maintained for that purpose.

OPTIONAL REDEMPTION

    At any time before May 15, 2004, PRIMEDIA may on any one or more occasions
redeem up to 35% of the aggregate principal amount of notes (which includes
additional notes, if any) originally issued under the Indenture at a redemption
price of 108.875% of the principal amount of those notes, plus accrued and
unpaid interest to the redemption date, with the net cash proceeds of one or
more Equity Offerings; PROVIDED that:

    (1) at least 65% of the aggregate principal amount of notes (which includes
       additional notes, if any) originally issued remains outstanding
       immediately after the occurrence of each of those redemptions (excluding
       notes held by PRIMEDIA and its Subsidiaries); and

    (2) any redemption must occur within 60 days of the date of closing of that
       Equity Offering.

    Except as provided in the preceding paragraph and other than in connection
with a Change of Control, as described below, PRIMEDIA may not redeem the notes
before May 15, 2006. On or after May 15, 2006, PRIMEDIA may, at its option,
redeem the notes, in whole or in part, upon not less than 30 nor more than
60 days' notice, at the redemption prices (expressed as percentages of the
principal amount) set forth below, plus accrued and unpaid interest on the notes
being redeemed to the applicable redemption date, if redeemed during the
12-month period beginning May 15 of the years indicated below:

<Table>

2008........................................................    101.479%
2009 and thereafter.........................................    100.000%
</Table>

    If the optional redemption date is on or after an interest record date and
on or before the related interest payment date, the accrued and unpaid interest,
if any, will be paid to the person or entity in whose name the note is
registered at the close of business on that record date, and no additional
interest will be payable to holders whose notes will be subject to redemption by
PRIMEDIA.

    The Credit Facilities restrict the optional redemption or the prepayment of
the notes, and the indentures governing the Outstanding Notes make that
redemption or prepayment a Restricted Payment (as defined in the indentures
governing the Outstanding Notes).

SINKING FUND

    There will be no sinking fund payments for the notes.

CHANGE OF CONTROL

    HOLDERS' RIGHT TO REQUIRE REPURCHASE UPON CHANGE OF CONTROL

    If a Change of Control occurs, each holder will have the right to require
PRIMEDIA to repurchase all or any part (equal to $1,000 or any integral multiple
of $1,000) of that holder's notes pursuant to the offer described below (the
"Change of Control Offer") at a purchase price equal to 101% of the aggregate
principal amount plus accrued and unpaid interest, if any, to the date of
purchase (the "Change of Control Payment"). The redemption prices for optional
redemptions in the event of a Change of Control described in the next subsection
would in all cases be equal to or greater than this repurchase price. Because of
the highly leveraged nature of PRIMEDIA, there can be no assurance that PRIMEDIA
will have sufficient funds to repurchase the notes in the event of a Change of
Control. The right of the holders of the notes to require PRIMEDIA to repurchase
the notes in the event of a Change of Control cannot be waived by the Trustee,
PRIMEDIA or PRIMEDIA's board of directors.

    Within 40 days following any Change of Control, PRIMEDIA will mail a notice
to each holder stating:

    (1) that the Change of Control Offer is being made pursuant to the CHANGE OF
       CONTROL covenant and that all notes tendered will be accepted for
       payment;

    (2) the purchase price and the purchase date, which will be no earlier than
       30 days nor later than 60 days from the date that notice is mailed (the
       "Change of Control Payment Date");

    (3) that any notes not tendered will continue to accrue interest;

    (4) that, unless PRIMEDIA defaults in the payment of the Change of Control
       Payment, all notes accepted for payment pursuant to the Change of Control
       Offer will cease to accrue interest after the Change of Control Payment
       Date;

    (5) that holders electing to have any notes purchased pursuant to a Change
       of Control Offer will be required to surrender the notes, with the form
       entitled "Option of Holder to Elect Purchase" on the reverse of each note
       completed, to the paying agent at the address specified in the notice
       before the close of business on the Business Day preceding the Change of
       Control Payment Date;

    (6) that holders will be entitled to withdraw their election if the paying
       agent receives, not later than the close of business on the third
       Business Day preceding the Change of Control Payment Date, a telegram,
       telex, facsimile transmission or letter setting forth the name of the
       holder, the principal amount of the notes delivered for purchase and a
       statement that that holder is withdrawing his election to have those
       notes purchased; and

    (7) that holders whose notes are being purchased only in part will be issued
       new notes equal in principal amount to the unpurchased portion of the
       notes surrendered.

    On the Change of Control Payment Date, PRIMEDIA will, to the extent lawful:

    (1) accept for payment notes or portions of notes tendered pursuant to the
       Change of Control Offer;

    (2) deposit with the paying agent an amount equal to the Change of Control
       Payment in respect of all notes or portions of notes so tendered; and

                                       39
<Page>
    (3) deliver or cause to be delivered to the Trustee the notes so accepted
       together with an officers' certificate stating the notes or portions of
       notes that were tendered to PRIMEDIA.

    The paying agent will promptly mail to each holder of notes so accepted
payment in an amount equal to the purchase price for those notes, and the
Trustee will promptly authenticate and mail to that holder a note equal in
principal amount to any unpurchased portion of the notes surrendered; PROVIDED
that each of those notes will be in a principal amount of $1,000 or integral
multiples of $1,000.

    PRIMEDIA will publicly announce the results of the Change of Control Offer
on or as soon as practicable after the Change of Control Payment Date.

    Indebtedness under the Credit Facilities will automatically accelerate upon
the earlier of (i) 30 days from the Change of Control and the Change of Control
Payment Date. If PRIMEDIA has insufficient funds with which to repay the
indebtedness under the Credit Facilities and to repurchase the notes and any
other senior indebtedness that is required to be repurchased upon a Change of
Control, including the Outstanding Notes, the holders of notes will have a claim
on the funds of PRIMEDIA equal to that of the lenders under the Credit
Facilities and of the holders of any such other senior indebtedness, including
the holders of the Outstanding Notes.

    The provisions described above that require PRIMEDIA to make a Change of
Control Offer following a Change of Control will be applicable whether or not
any other provisions of the Indenture are applicable to that Change of Control.
Except as described above with respect to a Change of Control, the Indenture
does not contain provisions that permit the holders of the notes to require that
PRIMEDIA repurchase or redeem the notes in the event of a takeover,
recapitalization or similar transaction.

    PRIMEDIA will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements included
in the Indenture applicable to a Change of Control Offer made by PRIMEDIA and
purchases all notes validly tendered and not withdrawn under that Change of
Control Offer.

    OPTIONAL REDEMPTION UPON CHANGE OF CONTROL

    In addition to the rights set forth under "Optional Redemption," PRIMEDIA
may, at its option, redeem the notes, in whole or in part, at any time within
160 days after a Change of Control upon not less than 30 nor more than 60 days'
prior notice to each holder of notes to be redeemed, at a redemption price equal
to the sum of (i) the then outstanding principal amount of the notes being
redeemed plus (ii) accrued and unpaid interest, if any, to the redemption date
plus (iii) the Applicable Premium.

    The following definitions are used to determine the Applicable Premium:

    "Applicable Premium" with respect to the notes will be calculated with
respect to the date of redemption and will equal the greater of (i) 1.0% of the
then outstanding principal amount of the notes and (ii) the excess of (A) the
present value of the required interest and principal payments due on the notes,
computed using a discount rate equal to the Treasury Rate plus the Applicable
Spread, over (B) the then outstanding principal amount of the notes.

    "Applicable Spread," for purposes of the Indenture, is defined as one half
of one percent.

    "Treasury Rate," for purposes of the Indenture, is defined as the yield to
maturity at the time of computation of United States Treasury securities with a
constant maturity (as compiled by and published in the most recent Federal
Reserve Statistical Release H.15 (519) which has become publicly available at
least two Business Days prior to the date fixed for prepayment (or, if that
Statistical Release is no longer published, any publicly available source of
similar market data)) most nearly equal

                                       40
<Page>
to the then remaining Average Life of the notes; PROVIDED, that if the Average
Life of the notes is not equal to the constant maturity of a United States
Treasury security for which a weekly average yield is given, the Treasury Rate
will be obtained by linear interpolation (calculated to the nearest one-twelfth
of a year) from the weekly average yields of United States Treasury securities
for which those yields are given, except that if the Average Life of the notes
is less than one year, the weekly average yield on actually traded United States
Treasury securities adjusted to a constant maturity of one year will be used.

    The redemption prices in an optional redemption upon a Change of Control
will in all cases be equal to or higher than the price applicable to a
repurchase upon a Change of Control required by a holder. If PRIMEDIA were to
effect an optional Change of Control redemption before the Change of Control
Payment Date, holders that had previously tendered notes to PRIMEDIA for
repurchase could withdraw those tenders before the Change of Control Payment
Date so as to participate in the optional redemption. However, PRIMEDIA would
have no obligation to announce an optional Change of Control redemption before
the closing of the mandatory Change of Control Offer.

    PRIMEDIA will comply with the requirements of Rule 14e-1 under the Exchange
Act and any other securities laws and regulations promulgated under that act to
the extent those laws and regulations are applicable in connection with the
repurchase of the notes triggered by a Change of Control.

SELECTION AND NOTICE

    If less than all of the notes are to be redeemed at any time, the Trustee
will select notes for redemption as follows:

    (1) if the notes are listed, in compliance with the requirements of the
       principal national securities exchange on which the notes are listed; or

    (2) if the notes are not so listed, on a pro rata basis, by lot or by such
       method as the Trustee will deem fair and appropriate.

    No notes of $1,000 or less will be redeemed in part. Notice of redemption
will be mailed by first class mail at least 30 but not more than 60 days before
the redemption date to each holder of notes to be redeemed at its registered
address.

    If any note is to be redeemed in part only, the notice of redemption that
relates to that note will state the portion of the principal amount of that note
to be redeemed. A note in principal amount equal to the unredeemed portion of
that note will be issued in the name of the holder of that note upon
cancellation of the original notes. On and after the redemption date, interest
ceases to accrue on notes or portions of them called for redemption.

CERTAIN COVENANTS

    LIMITATIONS ON RESTRICTED PAYMENTS

    PRIMEDIA will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly:

    (i) declare or pay any dividend or make any distribution on account of
        PRIMEDIA or any of its Restricted Subsidiaries' Capital Stock or other
        Equity Interests, other than (A) dividends or distributions payable in
        Equity Interests, other than Redeemable Stock, of PRIMEDIA or that
        Restricted Subsidiary, (B) dividends or distributions payable to
        PRIMEDIA or any of its Restricted Subsidiaries or (C) dividends or
        distributions by a Partially Owned Restricted Subsidiary so long as, in
        the case of any dividend or distribution payable on or in respect of any
        class or series of securities issued by that Partially Owned Restricted
        Subsidiary, PRIMEDIA or a Restricted Subsidiary of PRIMEDIA receives at
        least its pro rata share of

                                       41
<Page>
        that dividend or distribution in accordance with its Equity Interests in
        that class or series of securities;

    (ii) (A) voluntarily purchase, redeem or otherwise acquire or retire for
         value any preferred stock of PRIMEDIA or any of its Restricted
         Subsidiaries which, by its terms, is exchangeable for any Indebtedness
         ("Exchangeable Preferred Stock") that is PARI PASSU with or
         subordinated in right of payment to the notes or (B) purchase, redeem
         or otherwise acquire or retire for value any Equity Interests (other

         or any of its Restricted Subsidiaries;

   (iii) voluntarily purchase, repay, redeem, defease (including, but not
         limited to, covenant or legal defeasance) or otherwise acquire or
         retire for value any Indebtedness that is subordinated in right of
         payment to the notes (other than in connection with the refunding or
         refinancing of that Indebtedness), except a payment of interest or
         principal at the stated maturity of that Indebtedness or in
         anticipation of satisfying a sinking fund obligation, principal
         installment or final maturity, in each case due within one year of that
         payment, and other than Indebtedness between and among PRIMEDIA and its
         Restricted Subsidiaries; or

    (iv) make Investments in Restricted Payment Unrestricted Subsidiaries (the
         foregoing actions set forth in clauses (i) through (iv) being referred
         to as "Restricted Payments"),

if, at the time of that Restricted Payment:

       (a) a Default or Event of Default shall have occurred and be continuing
           or shall occur as a consequence thereof; or

       (b) PRIMEDIA could not incur at least $1.00 of additional Indebtedness
           under the first paragraph of the INCURRENCE OF INDEBTEDNESS covenant
           (without giving effect to clauses (i) through (xvi) of the second
           paragraph of that covenant), which calculation will be made on a pro
           forma basis deducting from Adjusted Consolidated Net Income the
           amount of any Investment PRIMEDIA has made in an Unrestricted
           Subsidiary during the relevant period and any Investment PRIMEDIA
           intends to make in an Unrestricted Subsidiary, to the extent that
           that Investment is made with amounts included in Adjusted
           Consolidated Net Income as a result of Transfers described in
           clause (c)(x) below or clause (c)(y) of the INVESTMENTS IN
           UNRESTRICTED SUBSIDIARIES covenant; or

       (c) that Restricted Payment, together with the aggregate of all other
           Restricted Payments made after May 13, 1992, exceeds the sum of the
           following:

           (w) 50% of the amount of the Adjusted Consolidated Net Income (other
               than amounts included in the next succeeding clause (c)(x)) of
               PRIMEDIA for the period (taken as one accounting period) from the
               beginning of the first quarter commencing immediately after
               May 13, 1992 through the end of PRIMEDIA's fiscal quarter ending
               immediately prior to the time of that Restricted Payment (or, if
               Adjusted Consolidated Net Income for that period is a deficit,
               100% of that deficit); PLUS

           (x) 100% of the amount of all Transfers from a Restricted Payment
               Unrestricted Subsidiary up to the aggregate amount of the
               Investment (after taking into account all prior Transfers from
               that Restricted Payment Unrestricted Subsidiary) in that
               Restricted Payment Unrestricted Subsidiary (valued in each case
               as provided in the definition of "Investment"); PLUS

           (y) in the event of a designation of a Restricted Payment
               Unrestricted Subsidiary as a Restricted Subsidiary, 100% of an
               amount equal to the greater of (A) the fair market value of that
               Subsidiary as determined by the board of directors of PRIMEDIA in

                                       42
<Page>
               good faith (or, if that fair market value may exceed
               $25.0 million, as determined in writing by an independent
               investment banking firm of nationally recognized standing) at the
               time of the redesignation of that Restricted Payment Unrestricted
               Subsidiary as a Restricted Subsidiary and (B) the Consolidated
               Net Cash Flow generated by that Subsidiary for the period (taken
               as one accounting period) from the beginning of its first fiscal
               quarter commencing immediately after the date of its designation
               as a Restricted Payment Unrestricted Subsidiary through that
               Subsidiary's fiscal quarter ending immediately prior to its
               designation as a Restricted Subsidiary (or if that Consolidated
               Net Cash Flow for that period is a deficit, 100% of that
               deficit); PLUS

           (z) 100% of the aggregate net cash proceeds received by PRIMEDIA from
               (i) the issuance or sale of Equity Interests of PRIMEDIA (other
               than Equity Interests issued or sold to a Restricted Subsidiary
               of PRIMEDIA and other than Redeemable Stock) or (ii) the sale of
               the stock of an Unrestricted Subsidiary or the sale of all or
               substantially all of the assets of an Unrestricted Subsidiary to
               the extent that a liquidating dividend is paid to PRIMEDIA or any
               Restricted Subsidiary from the proceeds of that sale;

       PROVIDED, HOWEVER, that for purposes of making Investments in
       Unrestricted Subsidiaries, if the amount determined in accordance with
       clauses (w) or (y) above is a deficit, that deficit will be excluded from
       the computation of this clause (c); PROVIDED, FURTHER, that all those
       amounts applied under this clause (c) will not be available for
       application under clause (c) of the INVESTMENTS IN UNRESTRICTED
       SUBSIDIARIES covenant. As of June 30, 2001, the amount available for
       Restricted Payments under clause (c) was approximately $702.2 million.

    The foregoing provisions will not prohibit:

    (i) the payment of any dividend within 60 days after the date of declaration
        of that dividend, if at that date of declaration the payment would have
        complied with the provisions of the Indenture;

    (ii) (A) the retirement of any shares of PRIMEDIA's Capital Stock (the
         "Retired Capital Stock") either (1) in exchange for or (2) out of the
         net proceeds of the substantially concurrent sale (other than to a
         Restricted Subsidiary of PRIMEDIA) of other shares of, PRIMEDIA's
         Capital Stock (the "Refunding Capital Stock") other than any Redeemable
         Stock, and (B) if immediately prior to the retirement of Retired
         Capital Stock the declaration and payment of dividends on the Retired
         Capital Stock was permitted under either clause (iii) or (vii) of this
         paragraph, the declaration and payment of dividends on the Refunding
         Capital Stock in an aggregate amount per year no greater than the
         aggregate amount of dividends per year that was declarable and payable
         on the Retired Capital Stock immediately prior to the retirement;

   (iii) the declaration and payment of dividends to the holders of Series D
         Preferred Stock, Series F Preferred Stock and Series H Preferred Stock;

    (iv) the repurchase, redemption or other acquisition or retirement for value
         of any Equity Interests of PRIMEDIA issued to present and former
         members of management of PRIMEDIA and its Subsidiaries under
         subscription and option agreements in effect on the date of the
         Indenture or under any stock option plan of About.com, Inc. existing on
         the date of the Indenture and Equity Interests of PRIMEDIA issued to
         future members of management under subscription agreements executed
         after the date of the Indenture, containing provisions for the
         repurchase of those Equity Interests upon death, disability or
         termination of employment of those persons which are substantially
         identical to those contained in the subscription agreements in effect
         on the date of the Indenture;

                                       43

    (v) the declaration and payment of dividends on PRIMEDIA's common stock of
        up to $25.0 million per annum plus 6% per annum of the net proceeds
        received at any time by PRIMEDIA from (a) the issue or sale of its
        common stock or (b)(1) the issuance of securities convertible into its
        common stock (other than any such convertible securities issued to
        (A) members of PRIMEDIA's management or its board of directors and
        (B) any Subsidiary of PRIMEDIA) and (2) the conversion of those
        convertible securities into PRIMEDIA's common stock, in both cases at
        the time of the conversion into common stock;

    (vi) the repurchase, redemption or other acquisition or retirement for value
         of Indebtedness of PRIMEDIA or any Guarantor which is subordinated in
         right of payment to the notes either (A) in exchange for or (B) with
         the proceeds of the issuance of, Equity Interests (other than
         Redeemable Stock) of PRIMEDIA;

   (vii) the declaration and payment of dividends to holders of any class or
         series of PRIMEDIA's preferred stock issued after the date of the
         Indenture (including, without limitation, the declaration and payment
         of dividends on Refunding Capital Stock in excess of the dividends
         declarable and payable on Refunding Capital Stock under clause (ii) of
         this paragraph); PROVIDED that at the time of the issuance PRIMEDIA's
         Fixed Charge Coverage Ratio, after giving effect to the issuance, would
         be greater than 1.25 to 1;

  (viii) the redemption, repurchase or other acquisition or retirement for value
         of any Indebtedness of PRIMEDIA or any Guarantor which is subordinated
         in right of payment to the notes (A) with the proceeds of, or in
         exchange for, Indebtedness incurred pursuant to clause (vii) of the
         second paragraph of the INCURRENCE OF INDEBTEDNESS covenant or (B) if,
         after giving effect to that redemption, repurchase or retirement,
         PRIMEDIA could incur at least $1.00 of Indebtedness under the first
         paragraph of the INCURRENCE OF INDEBTEDNESS covenant (without giving
         effect to clauses (i) through (xvi) of the second paragraph of that
         covenant);

    (ix) the retirement of the Series D Preferred Stock, Series F Preferred
         Stock and Series H Preferred Stock in exchange for the issuance of the
         Class D Subordinated Debentures, Class F Subordinated Debentures and
         Class H Subordinated Debentures, respectively, under the respective
         certificates of designations relating to those series of preferred
         stock;

    (x) the purchase of Class D Subordinated Debentures, Class F Subordinated
        Debentures and Class H Subordinated Debentures in accordance with the
        CHANGE OF CONTROL covenants in the Class D Debenture Indenture, Class F
        Debenture Indenture and Class H Debenture Indenture, respectively;

    (xi) Investments in Unrestricted Subsidiaries having an aggregate fair
         market value, when taken together with all other Investments made under
         this clause (xi) that are at that time outstanding, not to exceed
         $50.0 million at the time of that Investment (with the fair market
         value of each Investment being measured at the time made and without
         giving effect to subsequent changes in value);

   (xii) the repurchase, retirement or other acquisition for value of Equity
         Interests of PRIMEDIA which are not held by KKR or any of its
         Affiliates; PROVIDED, that (A) the aggregate Restricted Payments made
         under this clause (xii) in any calendar year will not exceed
         $75.0 million and (B) immediately after giving effect to each
         Restricted Payment made under this clause (xii) on a pro forma basis,
         PRIMEDIA could incur at least $1.00 of additional Indebtedness under
         the first paragraph of the INCURRENCE OF INDEBTEDNESS covenant (without
         giving effect to clauses (i) through (xvi) of the second paragraph of
         that covenant);

  (xiii) other Restricted Payments in an aggregate amount not to exceed
         $50.0 million; and

                                       44
<Page>
   (xiv) any Investment made in a Securitization Subsidiary in connection with a
         Qualified Securitization Transaction, which Investment consists of the
         transfer of Receivables and Other Assets.

PROVIDED that in determining the aggregate amount expended for Restricted
Payments in accordance with paragraph (c) above:

    (1) no amounts expended under clauses (ii)(A)(1), (vi)(A), (viii), (ix) and
       (xiv) of this paragraph will be included;

    (2) 100% of the amounts expended under clauses (ii)(A)(2), (iv), (v),
       (vi)(B), (vii), (x), (xi), (xii) and (xiii) of this paragraph will be
       included;

    (3) 50% of the amounts expended under clause (iii) of this paragraph will be
       included;

    (4) amounts expended under clause (ii)(B) of this paragraph will be included
       to the extent previously included for the Retired Capital Stock; and

    (5) 100% of the amounts expended under clause (i) to the extent not included
       under subclauses (1) through (4) of this proviso will be included.

    For the purposes of determining compliance with this covenant, in the event
that a Restricted Payment meets the criteria of more than one of the categories
of permitted Restricted Payments described in clauses (i) through (xiv) above or
is entitled to be incurred under the first paragraph of this covenant (including
clauses (a), (b) and (c) of this covenant), PRIMEDIA will, in its sole
discretion, classify that Restricted Payment in any manner that complies with
the covenants described above and that Restricted Payment will be treated as
having been made under only one of those clauses or under the first paragraph of
this covenant.

    Not later than the date of making any Restricted Payment, PRIMEDIA will
deliver to the Trustee an officer's certificate stating that the Restricted
Payment is permitted and setting forth the basis upon which the calculations
required by the RESTRICTED PAYMENTS covenant were computed, which calculations
may be based on PRIMEDIA's latest available internal financial statements.

    INVESTMENTS IN UNRESTRICTED SUBSIDIARIES

    PRIMEDIA will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, make any Investment in any Unrestricted Subsidiary, if
at the time of that Investment:

    (a) a Default or Event of Default shall have occurred and be continuing or
       shall occur as a consequence thereof; or

    (b) immediately before that Investment, PRIMEDIA would not be permitted to
       incur at least $1.00 of Indebtedness under the first paragraph of the
       INCURRENCE OF INDEBTEDNESS covenant (without giving effect to clauses
       (i) through (xvi) of the second paragraph of that covenant), which
       calculation will be made on a pro forma basis deducting from Adjusted
       Consolidated Net Income the amount of any Investment PRIMEDIA has made in
       an Unrestricted Subsidiary during the relevant period and any Investment
       PRIMEDIA intends to make in an Unrestricted Subsidiary, to the extent
       that that Investment is made with amounts included in Adjusted
       Consolidated Net Income as a result of the Transfers described in
       clause (c)(x) of the LIMITATIONS ON RESTRICTED PAYMENTS covenant or
       clause (c)(y) below; or

    (c) that Investment, together with the aggregate of all other Investments in
       Unrestricted Subsidiaries made after May 13, 1992, exceeds:

       (w) the aggregate Consolidated Net Cash Flow of PRIMEDIA for the period
           (taken as one accounting period) from the beginning of the first
           quarter immediately after May 13, 1992, to the end of PRIMEDIA's most
           recently ended fiscal quarter at the time of that Investment; PLUS

                                       45
<Page>
       (x) 100% of the aggregate net cash proceeds received by PRIMEDIA from
           (i) the issue or sale of Equity Interests of PRIMEDIA (other than
           Equity Interests issued or sold to a Restricted Subsidiary of
           PRIMEDIA and other than Redeemable Stock) or (ii) the sale of the
           stock of an Unrestricted Subsidiary or the sale of all or
           substantially all of the assets of an Unrestricted Subsidiary to the
           extent that a liquidating dividend is paid to PRIMEDIA or any
           Restricted Subsidiary from the proceeds of that sale; PLUS

       (y) 100% of the amount of all Transfers from a Net Cash Flow Unrestricted
           Subsidiary up to the aggregate Investment (after taking into account
           all prior Transfers from that Net Cash Flow Unrestricted Subsidiary)
           in that Net Cash Flow Unrestricted Subsidiary resulting from those
           payments or transfers of assets (valued in each case as provided in
           the definition of "Investment"); PLUS

       (z) in the event of a designation of a Net Cash Flow Unrestricted
           Subsidiary as a Restricted Subsidiary, 100% of an amount equal to the
           greater of (A) the fair market value of that Subsidiary as determined
           by the board of directors of PRIMEDIA in good faith (or, if the fair
           market value may exceed $25.0 million, as determined in writing by an
           independent investment banking firm of nationally recognized
           standing) at the time of the redesignation of that Net Cash Flow
           Unrestricted Subsidiary as a Restricted Subsidiary and (B) the
           Consolidated Net Cash Flow generated by that Subsidiary for the
           period (taken as one accounting period) from the beginning of its
           first fiscal quarter commencing immediately after the date of its
           designation as a Net Cash Flow Unrestricted Subsidiary through that
           Subsidiary's fiscal quarter ending immediately prior to its
           designation as a Restricted Subsidiary (or if the Consolidated Net
           Cash Flow for that period is a deficit, 100% of that deficit);

PROVIDED that all those amounts applied under this clause (c) will not be
available for application under clause (c) of the RESTRICTED PAYMENTS covenant.
As of June 30, 2001, the amount available for Investments under clause (c) was
approximately $1.1 billion.

    The foregoing limitations will not apply to:

    (i) an Investment to the extent that it is to capitalize a Restricted
        Payment Unrestricted Subsidiary permitted under the LIMITATIONS ON
        RESTRICTED PAYMENTS covenant;

    (ii) an Investment to the extent that it is funded by the issuance of Equity
         Interests of PRIMEDIA to the extent net proceeds are not used to fund
         an optional redemption of notes;

   (iii) any Investment made in a Securitization Subsidiary in connection with a
         Qualified Securitization Transaction, which Investment consists of the
         transfer of Receivables and Other Assets; and

    (iv) Investments in Unrestricted Subsidiaries having an aggregate fair
         market value, when taken together with all other Investments made under
         this clause (iv) that are at that time outstanding, not to exceed
         $50.0 million at the time of that Investment (with the fair market
         value of each Investment being measured at the time made and without
         giving effect to subsequent changes in value).

    For the purposes of determining compliance with this covenant, in the event
that the making of an Investment in an Unrestricted Subsidiary meets the
criteria of more than one of the categories of permitted Investments in
Unrestricted Subsidiaries described in clauses (i) through (iv) above or is
entitled to be incurred under the first paragraph of this covenant (including
clauses (a), (b) and (c) of the first paragraph of this covenant), PRIMEDIA
will, in its sole discretion, classify that Investment in an Unrestricted
Subsidiary in any manner that complies with the covenants described above and

                                       46
<Page>
Investment in an Unrestricted Subsidiary will be treated as having been made
under only one of those clauses or under the first paragraph of this covenant.

    Each Net Cash Flow Unrestricted Subsidiary of PRIMEDIA will at all times
remain (1) wholly owned, directly or indirectly, by PRIMEDIA or a wholly owned
Restricted Subsidiary of PRIMEDIA or (2) a Subsidiary of PRIMEDIA so long as
there is no encumbrance or restriction on the ability of that Subsidiary to pay
dividends or make any other distributions on its Capital Stock, or pay any
Indebtedness or other obligations, to PRIMEDIA or any Restricted Subsidiary of
PRIMEDIA.

    Not later than the date of making any Investment described above, PRIMEDIA
will deliver to the Trustee an officer's certificate stating that the Investment
is permitted (including, without limitation, whether the Investment is
capitalizing a Net Cash Flow Unrestricted Subsidiary or a Restricted Payment
Unrestricted Subsidiary) and setting forth the basis upon which the calculations
required by the INVESTMENTS IN UNRESTRICTED SUBSIDIARIES covenant were computed,
which calculations may be based on PRIMEDIA's latest available internal
financial statements.

    DIVIDENDS AND PAYMENT RESTRICTIONS AFFECTING RESTRICTED SUBSIDIARIES

    PRIMEDIA will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create or otherwise cause or suffer to exist or
become effective any encumbrance or restriction on the ability of any Restricted
Subsidiary to:

    (i) pay dividends or make any other distributions on its Capital Stock, or
        any other interest or participation in, or measured by, its profits,
        owned by PRIMEDIA or any of its Restricted Subsidiaries, or pay any
        Indebtedness owed to PRIMEDIA or any of its Restricted Subsidiaries;

    (ii) make loans or advances to PRIMEDIA or any of its Restricted
         Subsidiaries; or

   (iii) transfer any of its properties or assets to PRIMEDIA or any of its
         Restricted Subsidiaries.

    However, the preceding restrictions will not apply to encumbrances or
restrictions existing by reason of:

    (A) the terms, as in effect on the date of the Indenture, of the Existing
       Indebtedness;

    (B) the terms, as in effect on the date of the Indenture, of the Bank Credit
       Facilities and the Outstanding Notes and the indentures governing the
       Outstanding Notes;

    (C) the terms of Indebtedness of PRIMEDIA incurred in accordance with the
       INCURRENCE OF INDEBTEDNESS covenant; PROVIDED that the terms of the
       Indebtedness constitute no greater encumbrance or restriction on the
       ability of any Restricted Subsidiary to pay dividends or make
       distributions, make loans or advances or transfer properties or assets
       than is permitted by this covenant;

    (D) the terms of the Indenture and the notes;

    (E) applicable law;

    (F) customary non-assignment provisions entered into in the ordinary course
       of business and consistent with past practices;

    (G) the terms of purchase money obligations for property acquired in the
       ordinary course of business, but only to the extent that those purchase
       money obligations restrict or prohibit the transfer of the property so
       acquired;

    (H) the terms of the Class D Subordinated Debentures, the Class D Debenture
       Indenture, the Class F Subordinated Debentures, the Class F Debenture
       Indenture, the Class H Subordinated Debentures and the Class H Debenture
       Indenture;

                                       47
<Page>
    (I) any encumbrance or restriction with respect to a Subsidiary of PRIMEDIA
       that is not a Subsidiary of PRIMEDIA on the date of the Indenture, which
       encumbrance or restriction is in existence at the time that person
       becomes a Subsidiary of PRIMEDIA or is created on the date it becomes a
       Subsidiary of PRIMEDIA;

    (J) any encumbrance or restriction with respect to a Subsidiary of PRIMEDIA
       imposed under an agreement which has been entered into for the sale or
       disposition of all or substantially all the Capital Stock or assets of
       that Subsidiary;

    (K) customary provisions in joint venture agreements and other similar
       agreements entered into in the ordinary course of business;

    (L) customary provisions contained in leases and other agreements entered
       into in the ordinary course of business;

    (M) the terms of any Indebtedness for borrowed money of any Partially Owned
       Restricted Subsidiary;

    (N) in the case of clause (iii) of the first paragraph of this covenant, any
       encumbrance or restriction contained in mortgages, pledges or other
       security agreements permitted under the Indenture securing Indebtedness
       of PRIMEDIA or a Restricted Subsidiary of PRIMEDIA to the extent that
       encumbrance or restriction restricts the transfer of the property subject
       to those mortgages, pledges or other security agreements;

    (O) any contractual requirements incurred with respect to Qualified
       Securitization Transactions relating exclusively to a Securitization
       Subsidiary that, in the good faith determination of the board of
       directors of PRIMEDIA, are customary in Qualified Securitization
       Transactions; or

    (P) any encumbrance or restriction existing under any agreement which
       refinances or replaces the agreements described in clauses (A), (B), (D),
       (H), (K), (L) and (M), PROVIDED that the terms and conditions of any of
       those encumbrances or restrictions contained in any of those agreements
       constitute no greater encumbrance or restriction on the ability of any
       Restricted Subsidiary to pay dividends or make distributions, make loans
       or advances or transfer properties or assets than those under or pursuant
       to the agreement evidencing the Indebtedness or obligations refinanced.

    Nothing contained in this covenant will prevent PRIMEDIA or a Restricted
Subsidiary from entering into any agreement permitting or providing for the
incurrence of Liens otherwise permitted by the LIMITATION ON LIENS covenant.

    INCURRENCE OF INDEBTEDNESS

    PRIMEDIA will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable with respect to any Indebtedness unless
PRIMEDIA's Debt to Consolidated Cash Flow Ratio for its four full fiscal
quarters ending immediately prior to the date that additional Indebtedness is
created, incurred, issued, assumed or guaranteed would have been no greater than
6.0 to 1, and that Indebtedness is not senior in right of payment to the notes;
PROVIDED that the calculation will give effect to (A) the incurrence of any
Indebtedness (after giving effect to the application of the proceeds of that
Indebtedness) in connection with the simultaneous acquisition of any person,
business, property or assets and (B) the Consolidated Cash Flow generated by
that acquired person, business, property or assets, giving effect in each case
to the incurrence of Indebtedness, application of proceeds and Consolidated Cash
Flow as if that acquisition had occurred at the beginning of that four quarter
period.

    For purposes of the previous paragraph, cash flow generated by any acquired
person, business, property or asset will be determined on the same basis as the
definition of Consolidated Cash Flow and

                                       48
<Page>
will be based on the actual earnings before interest, taxes, depreciation and
amortization of that acquired person, business, property or asset during the
immediately preceding four full fiscal quarters PLUS (y) (i) the savings in cost
of goods sold that would have resulted during that period from the effect of
using PRIMEDIA's actual costs for comparable goods and services during that
period and (ii) other savings in cost of goods sold or eliminations of selling,
general and administrative expenses as determined by PRIMEDIA in good faith in
its consideration of those acquisitions and consistent with PRIMEDIA's
experiences in acquisitions of similar businesses MINUS (z) the incremental
expenses that would be included in cost of goods sold and selling, general and
administrative expenses that would have been incurred by PRIMEDIA in the
operation of that acquired person, business, property or assets during that
period.

    The foregoing limitations will not apply to the incurrence of:

    (i) Indebtedness under the Credit Facilities (PROVIDED that the principal
        amount of that Indebtedness will not exceed $1.3 billion, less the
        amount of all repayments made in respect of term loans and of all
        permanent commitment reductions with respect to revolving loans (except
        to the extent, and only to the extent, that any required repayments of
        principal in connection with that commitment reduction are not made)
        made under the Credit Facilities (excluding those repayments and
        commitment reductions which occur substantially contemporaneously with a
        refinancing or a refunding thereof)), plus any amounts then available
        under clause (vi) of this paragraph;

    (ii) Existing Indebtedness;

   (iii) Indebtedness represented by the Outstanding Notes and the notes (but
         not any additional notes);

    (iv) Indebtedness represented by the Class D Subordinated Debentures issued
         in exchange for all the outstanding Series D Preferred Stock, the
         Class F Subordinated Debentures issued in exchange for all the
         outstanding Series F Preferred Stock and the Class H Subordinated
         Debentures issued in exchange for all the outstanding Series H
         Preferred Stock;

    (v) Capital Lease Obligations in an aggregate principal amount which, when
        aggregated with the principal amount of all other Capital Lease
        Obligations then outstanding and incurred pursuant to this clause (v)
        and including all Refinancing Indebtedness (as defined below) incurred
        to refund, refinance or replace any other Indebtedness incurred under
        this clause (v), does not exceed 5% of Total Assets;

    (vi) Indebtedness in an aggregate principal amount equal to the greater of
         (A) $225.0 million in the aggregate at any one time outstanding for
         PRIMEDIA and its Restricted Subsidiaries and (B) Indebtedness created,
         incurred, issued, assumed or guaranteed (x) by PRIMEDIA at any one time
         outstanding not in excess of 7% of the Consolidated Net Worth of
         PRIMEDIA at the time of the creation, incurrence, issuance, assumption
         or guarantee or (y) by any Restricted Subsidiary of PRIMEDIA at any one
         time outstanding not in excess of 7% of the Consolidated Net Worth of
         that Restricted Subsidiary at the time of the creation, incurrence,
         issuance, assumption or guarantee;

   (vii) Indebtedness created, incurred, issued, assumed or guaranteed in
         exchange for or the proceeds of which are used to extend, refinance,
         renew, replace, substitute or refund Indebtedness referred to in
         clauses (i) through (vi) above, including additional Indebtedness
         incurred to pay premiums and fees in connection with that additional
         Indebtedness (the "Refinancing Indebtedness"); PROVIDED, that (A) the
         principal amount of that Refinancing Indebtedness will not exceed the
         principal amount of Indebtedness (including unused commitments and
         additional Indebtedness incurred to pay premiums and fees in connection
         with that Indebtedness) so extended, refinanced, renewed, replaced,
         substituted or refunded

                                       49
<Page>
         PLUS any amounts then available under clause (vi) of this paragraph,
         (B) in the case of Refinancing Indebtedness for Indebtedness permitted
         under clauses (ii) and (iv) of this paragraph, the Refinancing
         Indebtedness permitted under clauses (ii) and (iv) of this paragraph
         will have an Average Life equal to or greater than the Average Life of
         the Indebtedness being extended, refinanced, renewed, replaced,
         substituted or refunded and (C) the Refinancing Indebtedness for
         Indebtedness permitted under clauses (ii) and (iv) of this paragraph
         will rank, in right of payment, no more senior than that Indebtedness
         being extended, refinanced, renewed, replaced, substituted or refunded
         and the Refinancing Indebtedness for Indebtedness permitted under
         clauses (i), (iii), (v) and (vi) of this paragraph will rank, in right
         of payment, PARI PASSU with or junior to the notes;

  (viii) intercompany Indebtedness incurred in connection with Investments in
         Unrestricted Subsidiaries; PROVIDED that those Investments are
         permitted by the LIMITATIONS ON RESTRICTED PAYMENTS covenant or the
         INVESTMENTS IN UNRESTRICTED SUBSIDIARIES covenant;

    (ix) Indebtedness under Currency Agreements and Interest Rate Agreements,
         PROVIDED that in the case of Currency Agreements which relate to other
         Indebtedness, those Currency Agreements do not increase the
         Indebtedness of PRIMEDIA outstanding other than as a result of
         fluctuations in foreign currency exchange rates;

    (x) Indebtedness arising from agreements providing for indemnification,
        adjustment of purchase price or similar obligations, or from guarantees
        or letters of credit, surety bonds or performance bonds securing any
        obligations of PRIMEDIA or any Restricted Subsidiary of PRIMEDIA under
        those agreements, incurred or assumed by the acquired Subsidiary in
        connection with the acquisition or disposition of any business, assets
        or Restricted Subsidiary of PRIMEDIA, other than guarantees or similar
        credit support by PRIMEDIA of Indebtedness incurred by any person
        acquiring all or any portion of that business, those assets or that
        Restricted Subsidiary for the purpose of financing that acquisition;
        PROVIDED that the maximum aggregate liability in respect of all that
        Indebtedness in the nature of those guarantees will at no time exceed
        the gross proceeds actually received from the sale of that business,
        those assets or that Restricted Subsidiary;

    (xi) Indebtedness arising from the honoring by a bank or other financial
         institution of a check, draft or similar instrument inadvertently
         (except in the case of daylight overdrafts, which will not be, and will
         not be deemed to be, inadvertent) drawn against insufficient funds in
         the ordinary course of business, PROVIDED that that Indebtedness is
         extinguished within three business days of its incurrence;

   (xii) Indebtedness of an entity at the time it is acquired as a Restricted
         Subsidiary, PROVIDED that that Indebtedness was not incurred or assumed
         by that entity in connection with or in anticipation of that
         acquisition;

  (xiii) Indebtedness between PRIMEDIA and any Restricted Subsidiary; PROVIDED
         that any subsequent transfer of any Capital Stock which results in any
         Restricted Subsidiary ceasing to be a Restricted Subsidiary or any
         subsequent transfer of such Indebtedness (other than to PRIMEDIA or
         another Restricted Subsidiary) shall be deemed in each case to
         constitute the incurrence of such Indebtedness by the obligor thereon;

   (xiv) Non-Compete Notes, not to exceed $50.0 million in aggregate principal
         amount less the amount of all principal repayments made in respect of
         those notes;

   (xv) PRIMEDIA's Obligations arising from the repurchase, redemption or other
        acquisitions of Capital Stock from management investors to the extent
        permitted by the LIMITATIONS ON RESTRICTED PAYMENTS covenant; and

                                       50
<Page>
   (xvi) Indebtedness incurred by a Securitization Subsidiary in connection with
         a Qualified Securitization Transaction that is Non-Recourse
         Indebtedness with respect to PRIMEDIA and its Restricted Subsidiaries
         (except for Standard Securitization Undertakings); PROVIDED that in the
         event such Securitization Subsidiary ceases to qualify as a
         Securitization Subsidiary or such Indebtedness ceases to constitute
         such Non-Recourse Indebtedness, such Indebtedness will be deemed, in
         each case, to be incurred at such time.

    For the purposes of determining the aggregate Indebtedness of any referent
person, Indebtedness will not include guarantees by any other person of that
Indebtedness.

    For the purposes of determining compliance with this covenant, in the event
that an item of Indebtedness meets the criteria of more than one of the
categories of permitted Indebtedness described in clauses (i) through
(xvi) above or is entitled to be incurred under the first paragraph of this
covenant, (A) PRIMEDIA will, in its sole discretion, classify that item of
Indebtedness in any manner that complies with the covenants described above;
PROVIDED that any Indebtedness classified as incurred pursuant to clause (vi)
above may later be reclassified as having been incurred pursuant to the first
paragraph of this covenant to the extent such reclassified Indebtedness could be
incurred pursuant to the first paragraph at the time of such reclassification;
and (B) that item of Indebtedness will be treated as having been incurred
pursuant to only one of those clauses or pursuant to the first paragraph of this
covenant except as otherwise set forth in the proviso to clause (A) above.
Accrual of interest, the accretion of accreted value and the payment of interest
in the form of additional Indebtedness will not be deemed to be an incurrence of
Indebtedness for purposes of this covenant.

    LIMITATIONS ON LIENS

    PRIMEDIA will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, create, incur, assume or suffer to exist any Lien
(other than Permitted Liens) on any of its assets or any income or profits from
any of its assets or assign or convey any right to receive income from any of
its assets unless the notes are equally and ratably secured with the
Indebtedness secured by that Lien for so long as that Indebtedness is so
secured. Upon the release and discharge of the initial Lien, any Lien created in
favor of the notes as a result of the initial Lien will be automatically
released.

    LIMITATIONS ON ASSET SALES

    PRIMEDIA will not, and will not permit any of its Restricted Subsidiaries
to, directly or indirectly, consummate an Asset Sale (including the sale of any
of the stock of any Subsidiary) unless at least 100% of the Net Proceeds from
that Asset Sale (or, in the case of a Partially Owned Restricted Subsidiary,
PRIMEDIA's Pro Rata Portion of the Net Proceeds, after repayment by that
Partially Owned Restricted Subsidiary of its Indebtedness) are applied first to
repay Obligations or reduce commitments under the Credit Facilities in
accordance with the terms of the Credit Facilities and second to offer to redeem
at par the Outstanding Notes and third to offer to redeem at par the notes.

    The foregoing application of Net Proceeds from Asset Sales is not required
in the case of:

    (i) sales or dispositions generating cash proceeds of less than, with
        respect to PRIMEDIA and its Restricted Subsidiaries, $2,500,000; and

    (ii) sales and dispositions as to which PRIMEDIA delivers a reinvestment
         notice and the proceeds are so reinvested in one or more
         communications, publishing, information, education or media assets or
         businesses within 12 months of the date the relevant Asset Sale is
         consummated.

                                       51
<Page>
    Notwithstanding the foregoing, neither PRIMEDIA nor its Restricted
Subsidiaries will be required to apply the Net Proceeds from any Asset Sale:

    (i) to the extent that the aggregate Net Proceeds from that Asset Sale,
        together with the Net Proceeds, if any, of any other Asset Sale which
        have not been previously applied, are less than $25,000,000; or

    (ii) to the extent that, and for so long as, those Net Proceeds cannot be so
         applied as a result of an encumbrance or restriction permitted under
         the LIMITATIONS ON LIENS covenant.

    The procedure for offering to redeem the notes in connection with Asset
Sales is substantially the same as the mechanism for redeeming the notes in
connection with a Change of Control.

    TRANSACTIONS WITH AFFILIATES

    Neither PRIMEDIA nor any of its Restricted Subsidiaries will make any loan,
advance, guarantee or capital contribution to, or for the benefit of, or sell,
lease, transfer or otherwise dispose of any of its properties or assets to, or
for the benefit of, or purchase or lease any property or assets from, or enter
into or amend any contract, agreement or understanding (each, an "Affiliate
Transaction") with, or for the benefit of:

    (i) any person (or any Affiliate of that person) holding 10% or more of any
        class of Capital Stock of PRIMEDIA or any of its Restricted
        Subsidiaries; or

    (ii) any Affiliate of PRIMEDIA or any of its Restricted Subsidiaries,

in each case involving aggregate payments or consideration in excess of
$5.0 million, unless:

       (a) that Affiliate Transaction is on terms that are not materially less
           favorable to PRIMEDIA or the relevant Restricted Subsidiary than
           those that would have been obtained in a comparable transaction by
           PRIMEDIA or that Restricted Subsidiary with an unrelated Person; and

       (b) PRIMEDIA delivers to the Trustee with respect to any Affiliate
           Transaction or series of related Affiliate Transactions involving
           aggregate consideration in excess of $10.0 million, a resolution
           adopted by the majority of the board of directors of PRIMEDIA
           approving that Affiliate Transaction and set forth in an officers'
           certificate certifying that that Affiliate Transaction complies with
           clause (a) above.

    The foregoing restrictions will not apply to:

    (i) the payment of an annual fee to KKR for the rendering of management
        consulting and financial services to PRIMEDIA and its Restricted
        Subsidiaries in an aggregate amount which is reasonable in relation to
        those services;

    (ii) the payment of transaction fees to KKR in amounts which are in
         accordance with past practices for the rendering of financial advice
         and services, in connection with acquisitions, dispositions and
         financings by PRIMEDIA and its Subsidiaries;

   (iii) loans to officers, directors and employees of PRIMEDIA and its
         Subsidiaries for business or personal purposes and other loans and
         advances to those officers, directors and employees for travel,
         entertainment, moving and other relocation expenses made in the
         ordinary course of business of PRIMEDIA and its Subsidiaries;

    (iv) any Restricted Payments not prohibited by the LIMITATIONS ON RESTRICTED
         PAYMENTS covenant or any Investment not prohibited by the INVESTMENTS
         IN UNRESTRICTED SUBSIDIARIES covenant;

    (v) transactions between or among any of PRIMEDIA and its Restricted
        Subsidiaries;

                                       52
<Page>
    (vi) allocation of corporate overhead to Unrestricted Subsidiaries on a
         basis not materially less favorable to PRIMEDIA than those allocations
         to Restricted Subsidiaries;

   (vii) the payment of reasonable and customary fees paid to, and indemnity
         provided on behalf of, officers, directors, employees or consultants of
         PRIMEDIA or any Restricted Subsidiary; or

  (viii) sales or other transfers or dispositions of Receivables and Other
         Assets transferred to a Securitization Subsidiary in a Qualified
         Securitization Transaction.

    MERGER, CONSOLIDATION OR SALE OF ASSETS

    PRIMEDIA may not consolidate with, merge with or into, or transfer all or
substantially all of its assets (as an entirety or substantially as an entirety
in one transaction or a series of related transactions), to any person (except a
wholly owned Restricted Subsidiary, PROVIDED that in connection with any merger
of PRIMEDIA with a Restricted Subsidiary of PRIMEDIA, no consideration (other
than common stock in the surviving corporation or PRIMEDIA) will be issued or
distributed to the shareholders of PRIMEDIA) or permit any person to merge with
or into it unless:

    (i) PRIMEDIA will be the continuing person, or the person (if other than
        PRIMEDIA) formed by that consolidation or into which PRIMEDIA is merged
        or to which the properties and assets of PRIMEDIA are transferred will
        be a corporation organized and existing under the laws of the United
        States or any State of the United States or the District of Columbia and
        will expressly assume, by a supplemental indenture, executed and
        delivered to the Trustee, in form satisfactory to the Trustee, all of
        the obligations of PRIMEDIA under the notes and Indenture; and

    (ii) immediately after giving effect to that transaction on a pro forma
         basis (a) no Default and no Event of Default under the Indenture will
         have occurred and be continuing and (b) PRIMEDIA could incur at least
         $1.00 of additional Indebtedness under the first paragraph of the
         INCURRENCE OF INDEBTEDNESS covenant (without giving effect to
         clause (i) through (xvi) of the second paragraph of that covenant) or
         the Debt to Consolidated Cash Flow Ratio equals or is less than the
         Debt to Consolidated Cash Flow Ratio immediately prior to that
         transaction.

    PAYMENTS FOR CONSENT

    Neither PRIMEDIA nor any of its Subsidiaries will, directly or indirectly,
pay or cause to be paid any consideration, whether by way of interest, fee or
otherwise, to any holder of any notes for or as an inducement to any consent,
waiver or amendment of any of the terms or provisions of the Indenture or the
notes, unless that consideration is offered to be paid or agreed to be paid to
all holders of the notes which so consent, waive or agree to amend in the time
frame set forth in solicitation documents relating to that consent, waiver or
agreement.

GUARANTEES

    GUARANTEES.  The new notes will be fully and unconditionally guaranteed on a
senior basis, jointly and severally, by each Guarantor. In the event that any
guarantee would constitute or result in a violation of any applicable fraudulent
conveyance or similar law of any relevant jurisdiction, the liability of any
Guarantor under that guarantee would be reduced to the maximum amount
permissible under the applicable fraudulent conveyance or similar law. The
foregoing guarantees (the "Guarantees") rank PARI PASSU with the guarantees made
for the benefit of the lenders under the Credit Facilities and with guarantees
made for the benefit of the holders of the Outstanding Notes. No Unrestricted
Subsidiary will become a guarantor of any Indebtedness of PRIMEDIA or any
Restricted Subsidiaries unless that Unrestricted Subsidiary becomes a guarantor
of the notes. In addition, no Securitization Subsidiary will become a guarantor
of the notes.

                                       53
<Page>
    RELEASES OF GUARANTEES

    Upon the sale or disposition (by merger or otherwise) of any Guarantor by
PRIMEDIA or any subsidiary of PRIMEDIA to any entity that is not an affiliate of
PRIMEDIA or any of its subsidiaries and which sale or disposition is otherwise
in compliance with the terms of the Indenture, that Guarantor will be released
from its obligations under its Guarantee if that Guarantor is sold or disposed
of for at least fair market value, evidenced by a resolution of the board of
directors of PRIMEDIA set forth in an officer's certificate delivered to the
Trustee; PROVIDED that the foregoing proviso will not apply to the sale or
disposition of a Guarantor in a foreclosure proceeding to the extent that that
proviso would be inconsistent with the requirements of the Uniform Commercial
Code.

EVENTS OF DEFAULT AND REMEDIES

    The Indenture provides that each of the following constitutes an "Event of
Default":

    (i) the failure to make any payment of interest on the notes when the same
        becomes due and payable and the continuance of that failure for a period
        of 30 days;

    (ii) the failure to make any payment when due of principal or premium on the
         notes, whether at maturity, or upon acceleration, redemption or
         otherwise;

   (iii) failure by PRIMEDIA to comply with any of its other agreements in the
         Indenture or the notes and that Default continues for 30 days after
         receipt of a written notice from the Trustee or holders of at least 30%
         of the aggregate principal amount of the notes then outstanding,
         specifying that Default and requiring that it be remedied;

    (iv) default under any mortgage, indenture or instrument under which there
         may be issued or by which there may be secured or evidenced any
         Indebtedness for money borrowed by PRIMEDIA or any of its Restricted
         Subsidiaries (or the payment of which is guaranteed by PRIMEDIA or any
         of its Restricted Subsidiaries) whether that Indebtedness or guarantee
         is now existing or thereafter created in the future, if either:

       (A) that default is the failure to pay the final scheduled principal
           installment in an amount of at least $10 million in respect of any
           such Indebtedness on the stated maturity date of that Indebtedness
           (after giving effect to any extension of the maturity date by the
           holder of that Indebtedness and after the expiration of any grace
           period in respect of the final scheduled principal installment
           contained in the instrument under which that Indebtedness is
           outstanding); or

       (B) as a result of that default the maturity of that Indebtedness has
           been accelerated prior to its express maturity and the principal
           amount of that Indebtedness, together with the principal amount of
           any other such Indebtedness the maturity of which has been
           accelerated, aggregates $20 million or more; PROVIDED that an Event
           of Default will not be deemed to occur with respect to any
           accelerated indebtedness which is repaid or prepaid within 20 days
           after that declaration;

    (v) failure by PRIMEDIA or any of its Significant Subsidiaries to pay
        certain final judgments that exceed $15 million individually or
        $25 million in the aggregate, which judgments are not discharged,
        satisfied, stayed, annulled or rescinded within 60 days after their
        entry;

    (vi) certain events of bankruptcy or insolvency with respect to PRIMEDIA or
         any of its Significant Subsidiaries; and

   (vii) except as permitted by the Indenture and the notes, the cessation of
         the effectiveness of the Guarantees or the finding in any judicial
         proceeding that the Guarantees are unenforceable or invalid or the
         denial or disaffirmation by any Guarantor of its obligations under its
         Guarantee.

                                       54
<Page>
    The term "Default" means any event which is, or after notice or passage of
time or both would be, an Event of Default.

    If a Default or an Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee will mail to each holder of the notes a notice
of the Default or Event of Default within 30 days after it occurs or, if later,
within 10 days after the Default or Event of Default becomes known to the
Trustee, unless the Default or Event of Default has been cured. Except in the
case of a Default or Event of Default in the payment of principal of, premium,
if any, or interest on any notes or that results from a failure to comply with
the CHANGE OF CONTROL covenant, the Trustee may withhold the notice if and so
long as a committee of its responsible officers in good faith determines that
withholding the notice is in the interest of the holders of the notes.

    If an Event of Default (other than an Event of Default with respect to
PRIMEDIA resulting from bankruptcy, insolvency or reorganization) occurs and is
continuing, the Trustee by written notice to PRIMEDIA, or the holders of at
least 30% of the principal amount of the notes then outstanding by written
notice to PRIMEDIA and the Trustee, may, and the Trustee at the request of those
holders will, declare all unpaid principal of, premium, if any, and accrued
interest on the notes to be due and payable, as specified below. Upon a
declaration of acceleration, the principal, premium, if any, and accrued
interest will be due and payable immediately. If an Event of Default resulting
from certain events of bankruptcy, insolvency or reorganization occurs with
respect to PRIMEDIA, all unpaid principal of, premium, if any, and accrued
interest on the notes then outstanding shall IPSO FACTO become and be
immediately due and payable without any declaration, notice or other act on the
part of the Trustee or any holder.

    The holders of at least a majority in principal amount of the notes by
notice to the Trustee may rescind an acceleration and its consequences upon
conditions provided in the Indenture. Subject to certain restrictions set forth
in the Indenture, the holders of at least a majority in principal amount of the
outstanding notes by notice to the Trustee may waive an existing Default or
Event of Default and its consequences (including waivers obtained in connection
with a tender offer or exchange offer for notes), except a continuing Default or
Event of Default in the payment of principal of, premium, if any, or interest
on, the notes (including, without limitation, pursuant to any mandatory or
optional redemption obligation under the Indenture). When a Default or Event of
Default is waived, it is cured and ceases.

    A holder of notes may not pursue any remedy with respect to the Indenture,
the notes or any Guarantee unless:

    (1) the holder gives to the Trustee written notice of a continuing Event of
       Default;

    (2) the holders of at least 30% in principal amount of the notes outstanding
       make a written request to the Trustee to pursue the remedy;

    (3) the holder or holders offer to the Trustee indemnity satisfactory to the
       Trustee against any loss, liability or expense (including, without
       limitation, fees of counsel);

    (4) the Trustee does not comply with the request within 30 days after
       receipt of the request and the offer of indemnity; and

    (5) during that 30-day period the holders of a majority in principal amount
       of the outstanding notes do not give the Trustee a direction which is
       inconsistent with the request.

    PRIMEDIA is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and PRIMEDIA is required upon becoming
aware of any Default or Event of Default to deliver a statement to the Trustee
specifying that Default or Event of Default.

                                       55
<Page>
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND SHAREHOLDERS

    No director, officer, employee, incorporator or shareholder of PRIMEDIA, as
such, will have any liability for any obligations of PRIMEDIA under the notes,
the Indenture, the Guarantees or the Registration Rights Agreement or for any
claim based on, in respect of, or by reason of, those obligations or their
creation. Each holder of the notes by accepting a note waives and releases all
such liability. The waiver and release are part of the consideration for
issuance of the notes. That waiver may not be effective to waive liabilities
under the federal securities laws, and it is the view of the Commission that
such a waiver is against public policy.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

    PRIMEDIA may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding notes ("Legal
Defeasance"), except for:

    (1) the rights of holders of outstanding notes to receive payments in
       respect of the principal of, premium, if any, and interest on the notes
       when those payments are due from the trust referred to below;

    (2) PRIMEDIA's obligations with respect to the notes concerning issuing
       temporary notes, registration of notes, mutilated, destroyed, lost or
       stolen notes and the maintenance of an office or agency for payment and
       money for security payments held in trust;

    (3) the rights, powers, trusts, duties and immunities of the Trustee, and
       PRIMEDIA's obligations in connection with those rights, powers, trusts,
       duties and immunities; and

    (4) the Legal Defeasance provisions of the Indenture.

    In addition, PRIMEDIA may, at its option and at any time, elect to have the
obligations of PRIMEDIA released with respect to certain covenants that are
described in the Indenture ("Covenant Defeasance") and thereafter any omission
to comply with those covenants will not constitute a Default or Event of Default
with respect to the notes. In the event Covenant Defeasance occurs, certain
events (not including non-payment or bankruptcy, receivership, rehabilitation
and insolvency events) described under "Events of Default" will no longer
constitute an Event of Default with respect to the notes.

    In order to exercise either Legal Defeasance or Covenant Defeasance:

    (1) PRIMEDIA must irrevocably deposit or cause to be deposited with the
       Trustee or the paying agent, in trust, money or direct noncallable
       obligations of or guaranteed by the United States of America in an amount
       sufficient, without reinvestment, to pay the principal of and interest on
       the outstanding notes on the stated maturity or on the applicable
       redemption date, as the case may be;

    (2) in the case of Legal Defeasance, PRIMEDIA will have delivered to the
       Trustee an opinion of counsel from nationally recognized counsel
       acceptable to the Trustee or a tax ruling from the Internal Revenue
       Service to the effect that the holders of the outstanding notes will not
       recognize income, gain or loss for federal income tax purposes as a
       result of the Legal Defeasance and will be subject to federal income tax
       on the same amount, in the same manner and at the same times as would
       have been the case if the Legal Defeasance had not occurred;

    (3) in the case of Covenant Defeasance, PRIMEDIA will have delivered to the
       Trustee an opinion of counsel from nationally recognized counsel
       acceptable to the Trustee confirming that the holders of the outstanding
       notes will not recognize income, gain or loss for federal income tax
       purposes as a result of the Covenant Defeasance and will be subject to
       federal

                                       56
<Page>
       income tax on the same amount, in the same manner and at the same times
       as would have been the case if the Covenant Defeasance had not occurred;

    (4) no Default or Event of Default will have occurred and be continuing (A)
       on the date of the deposit or (B) insofar as Events of Default from
       bankruptcy or insolvency events are concerned, at any time in the period
       ending on the 91st day after the date of the deposit; and

    (5) PRIMEDIA must deliver to the Trustee an officer's certificate and an
       opinion of counsel, each stating that all conditions precedent provided
       for relating to the Legal Defeasance or the Covenant Defeasance have been
       complied with.

TRANSFER AND EXCHANGE

    A holder may transfer or exchange notes in accordance with the Indenture.
The registrar and the Trustee may require a holder, among other things, to
furnish appropriate endorsements and transfer documents, and PRIMEDIA may
require a holder to pay any taxes and fees required by law or permitted by the
Indenture. PRIMEDIA is not required to transfer or exchange any note selected
for redemption. Also, PRIMEDIA is not required to transfer or exchange any note
for a period of 15 days before a selection of notes to be redeemed.

    The registered holder of a note will be treated as the owner of it for all
purposes.

AMENDMENT, SUPPLEMENT AND WAIVER

    Except as provided in the next succeeding paragraph, the Indenture, the
Guarantees or the notes may be amended or supplemented with the consent of the
holders of at least a majority in principal amount of the notes then outstanding
(including consents obtained in connection with a tender offer or exchange offer
for notes), and any existing default or compliance with any provision of the
Indenture or the notes may be waived with the consent of the holders of a
majority in principal amount of the then outstanding notes (including consents
obtained in connection with a tender offer or exchange offer for notes).

    Without the consent of each holder affected, an amendment or waiver may not
(with respect to any notes held by a non-consenting holder of notes):

    (i) reduce the principal amount of notes whose holders must consent to an
        amendment, supplement or waiver;

    (ii) reduce the principal of or change the fixed maturity of any notes or
         alter the provisions with respect to the redemption or purchase price
         in connection with repurchases of the notes with proceeds of Asset
         Sales, upon a Change of Control or otherwise;

   (iii) reduce the rate of or change the time for payment of interest on any
         notes;

    (iv) waive a Default or Event of Default in the payment of principal of or
         premium, if any, or interest on the notes (except a rescission of
         acceleration of the notes by the holders of at least a majority in
         aggregate principal amount of the notes);

    (v) make any notes payable in money other than that stated in the notes;

    (vi) make any change in the provisions of the Indenture relating to waivers
         of past Defaults or the rights of holders of notes to receive payments
         of principal of or interest on the notes;

   (vii) waive a redemption payment with respect to any note; or

  (viii) make any change in the foregoing.

                                       57
<Page>
    Notwithstanding the foregoing, without the consent of any holder of the
notes, PRIMEDIA and the Trustee may amend or supplement the Indenture or the
notes to:

    (1) cure any ambiguity, defect or inconsistency;

    (2) provide for uncertificated notes in addition to or in place of
       certificated notes;

    (3) provide for the assumption of PRIMEDIA's obligations to holders of the
       notes in the case of a merger or consolidation;

    (4) make any change that would provide any additional rights or benefits to
       the holders of the notes or that does not adversely affect the legal
       rights under the Indenture of any such holder; or

    (5) comply with requirements of the Commission in order to effect or
       maintain the qualification of the Indenture under the Trust Indenture
       Act.

CONCERNING THE TRUSTEE

    The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of PRIMEDIA, to obtain payment of claims in certain
cases or to realize on certain property received in respect of any such claim as
security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest it must eliminate
that conflict within 90 days, apply to the Commission for permission to continue
or resign.

    The holders of a majority in principal amount of the then outstanding notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
occurs (which is not cured), the Trustee will be required, in the exercise of
its power, to use the degree of care of a prudent person in the conduct of its
own affairs. Subject to those provisions, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request of any of the holders of the notes, unless they offer to the Trustee
security and indemnity satisfactory to it against any loss, liability or
expense.

EXCHANGE OFFER, REGISTRATION RIGHTS

    On May 8, 2001, PRIMEDIA, the Guarantors and the initial purchasers entered
into the Registration Rights Agreement. Under the Registration Rights Agreement,
PRIMEDIA agreed, for the benefit of the holders of the Transfer Restricted
Securities, that PRIMEDIA will, at its cost, (1) cause to be filed, on or before
120 days after the Closing Date, the Exchange Offer Registration Statement with
the SEC under the Securities Act concerning the Exchange Offer, and (2) (a) use
its reasonable best efforts to cause the Exchange Offer Registration Statement
to be declared effective by the SEC on or before 200 days after the closing Date
and (b) cause the Exchange Offer to remain open for the minimum period required
by applicable federal and state securities laws, PROVIDED, HOWEVER, that in no
event will that period be less than 20 business days. For each Transfer
Restricted Security surrendered to PRIMEDIA and accepted for exchange in the
exchange offer, the holder of that Transfer Restricted Security will receive a
new note having a principal amount equal to that of the surrendered Transfer
Restricted Security.

    Based upon no-action letters issued by the staff of the SEC to third
parties, PRIMEDIA believes that the new notes issued in the exchange offer in
exchange for Transfer Restricted Securities would in general be freely
transferable after the exchange offer without further registration under the
Securities Act if the holder of the new notes represents (1) that it is not an
"affiliate" as defined in Rule 405 under the Securities Act, of PRIMEDIA,
(2) that it is acquiring the new notes in the ordinary course of its business
and (3) that it has no arrangement or understanding with any person to
participate in

                                       58
<Page>
the distribution, within the meaning of the Securities Act, of the new notes,
PROVIDED that, in the case of broker-dealers, a prospectus meeting the
requirements of the Securities Act be delivered as required. However, the SEC
has not considered the exchange offer in the context of a no-action letter and
there can be no assurance that the staff of the SEC would make a similar
determination with respect to the exchange offer as in those other
circumstances. Holders of Transfer Restricted Securities wishing to accept the
exchange offer must represent to PRIMEDIA that those conditions have been met.
Each broker-dealer that receives new notes for its own account in the exchange
offer, where it acquired the new notes exchanged for the new notes for its own
account as a result of market-making or other trading activities, must
acknowledge that it will deliver a prospectus in connection with the resale of
the new notes. The letter of transmittal states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an underwriter within the meaning of the Securities Act.

    A holder of Transfer Restricted Securities other than certain specified
holders, who wishes to exchange those Transfer Restricted Securities for new
notes in the exchange offer will be required to represent that any new notes to
be received by it will be acquired in the ordinary course of its business, and
that at the time of the commencement of the exchange offer it has no arrangement
or understanding with any person to participate in the distribution, within the
meaning of the Securities Act, of the new notes and that it is not an
"affiliate" of PRIMEDIA, as defined in Rule 405 under the Securities Act, or if
it is an affiliate, that it will comply with the registration and prospectus
delivery requirements of the Securities Act to the extent applicable.

    If the exchange offer is not permitted by applicable law or SEC policy or
(2) if any Holder of Transfer Restricted Securities will notify PRIMEDIA within
20 business days following the consummation of the exchange offer that (a) the
holder was prohibited by law or SEC policy from participating in the exchange
offer or (b) the holder may not resell the new notes acquired by it in the
exchange offer to the public without delivering a prospectus and the Prospectus
contained in the Exchange Offer Registration Statement is not appropriate or
available for the resales by the holders or (c) the holder is a broker-dealer
and holds old notes acquired directly from the Company or any of its affiliates,
then PRIMEDIA will, at its cost, (A) cause to be filed a shelf registration
statement (the "Shelf Registration Statement") covering resales of the Transfer
Restricted Securities, (B) use its reasonable best efforts to cause the shelf
Registration Statement to be declared effective under the Securities Act and
(C) use its reasonable best efforts to keep the Shelf Registration Statement
effective until two years after its effective date or any shorter period ending
when all resales of Transfer Restricted Securities covered by the Shelf
Registration Statement have been made. A holder selling those Transfer
Restricted Securities under the Shelf Registration Statement generally would be
required to be named as a selling security holder in the related prospectus and
to deliver a prospectus to purchasers, will be subject to certain of the civil
liability provisions under the Securities Act in connection with those sales and
will be bound by the provisions of the Registration Rights Agreement which are
applicable to that holder, including certain indemnification obligations.

    If

           (a)  PRIMEDIA fails to file any of the registration statements
                required by the Registration Rights Agreement on or before the
                date specified for such filing;

           (b)  any of such registration statements is not declared effective by
                the Commission on or prior to the date specified for such
                effectiveness (the "Effectiveness Target Date");

           (c)  PRIMEDIA fails to consummate the exchange offer within 30 days
                of the Effectiveness Target Date with respect to the Exchange
                Offer Registration Statement; or

                                       59
<Page>
           (d)  the Shelf Registration Statement or the Exchange Offer
                Registration Statement is declared effective but thereafter
                ceases to be effective or usable in connection with resales of
                Transfer Restricted Securities during the periods specified in
                the Registration Rights Agreement

(each such event referred to in clauses (a) through (d) above a "Registration
Default"), then PRIMEDIA will pay liquidated damages to each holder of Transfer
Restricted Securities ("Liquidated Damages"). Liquidated Damages will accrue,
with respect to the first 90-day period (or portion thereof) immediately
following the occurrence of the first Registration Default, at a rate of 0.25%
per annum of the aggregate principal amount of the outstanding notes on the date
of such Registration Default, payable in cash semiannually in arrears on each
interest payment date, commencing on the date of such Registration Default. The
rate of the Liquidated Damages will increase by an additional 0.25% per annum at
the beginning of each subsequent 90-day period (or portion thereof) until all
Registration Defaults have been cured, up to a maximum rate of Liquidated
Damages for all Registration Defaults of 0.50% per annum.

    The Registration Rights Agreement will provide that the Liquidated Damages
specified above will be the exclusive remedy available to holders of Transfer
Restricted Securities for any failure by PRIMEDIA to comply with the
registration requirements of the Registration Rights Agreement.

    The summary in this prospectus of certain provisions of the Registration
Rights Agreement does not purport to be complete and is subject to, and is
qualified in its entirety by, all of the provisions of the Registration Rights
Agreement.

BOOK-ENTRY; DELIVERY AND FORM

    The notes will initially be represented in the form of one or more global
notes in definitive, fully-registered book-entry form, without interest coupons
that will be deposited with or on behalf of The Depository Trust Company, or
DTC, and registered in the name of DTC or its participants.

    Except as set forth below, the global notes may be transferred, in whole and
not in part, solely to another nominee of DTC or to a successor of DTC or its
nominee. Beneficial interests in the global notes may not be exchanged for notes
in physical, certificated form except in the limited circumstances described
below.

DEPOSITORY PROCEDURES

    The following description of the operations and procedures of the DTC are
provided solely as a matter of convenience. These operations and procedures are
solely within the control of the respective settlement systems and are subject
to changes by them. PRIMEDIA takes no responsibility for these operations and
procedures and urges investors to contact the system or their participants
directly to discuss these matters.

    The DTC has advised PRIMEDIA that the DTC is a limited-purpose trust company
created to hold securities for its participating organizations (collectively,
the "Participants") and to facilitate the clearance and settlement of
transactions in those securities between Participants through electronic
book-entry changes in accounts of its Participants. The Participants include
securities brokers and dealers (including the initial purchasers), banks, trust
companies, clearing corporations and certain other organizations. Access to
DTC's system is also available to other entities, such as banks, brokers,
dealers and trust companies, that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly (collectively,
the "Indirect Participants"). Persons who are not Participants may beneficially
own securities held by or on behalf of DTC only through the Participants or the
Indirect Participants. The ownership interests in, and transfers of ownership
interests in, each security held by or on behalf of DTC are recorded on the
records of the Participants and Indirect Participants.

                                       60
<Page>
    The DTC has also advised PRIMEDIA that, pursuant to procedures established
by it:

    (1) upon deposit of the Global Notes, the DTC will credit the accounts of
       Participants designated by the initial purchasers with portions of the
       principal amount of the Global Notes; and

    (2) ownership of these interests in the Global Notes will be shown on, and
       the transfer of ownership of these interests will be effected only
       through, records maintained by the DTC (with respect to the Participants)
       or by the Participants and the Indirect Participants (with respect to
       other owners of beneficial interest in the Global Notes).

    The laws of some states require that certain persons take physical delivery
in definitive form of securities that they own. Consequently, the ability to
transfer beneficial interests in a Global Note to those persons will be limited
to that extent. Because the DTC can act only on behalf of Participants, which in
turn act on behalf of Indirect Participants, the ability of a person having
beneficial interests in a Global Note to pledge those interests to persons that
do not participate in the DTC system, or otherwise take actions in respect of
those interests, may be affected by the lack of a physical certificate
evidencing those interests.

    EXCEPT AS DESCRIBED BELOW, OWNERS OF INTERESTS IN THE GLOBAL NOTES WILL NOT
HAVE NOTES REGISTERED IN THEIR NAMES, WILL NOT RECEIVE PHYSICAL DELIVERY OF
NOTES IN CERTIFICATED FORM AND WILL NOT BE CONSIDERED THE REGISTERED OWNERS OR
HOLDERS OF THE GLOBAL NOTES UNDER THE INDENTURE FOR ANY PURPOSE.

    Payments in respect of the principal of, and interest and premium and
liquidated damages, if any, on a Global Note registered in the name of the DTC
or its nominee will be payable to the DTC in its capacity as the registered
holder under the indenture. Under the terms of the indenture, PRIMEDIA and the
trustee will treat the persons in whose names the notes, including the Global
Notes, are registered as the owners of the notes for the purpose of receiving
payments and for all other purposes. Consequently, neither PRIMEDIA, the trustee
nor any agent of PRIMEDIA or the trustee has or will have any responsibility or
liability for:

    (1) any aspect of the DTC's records or any Participant's or Indirect
       Participant's records relating to or payments made on account of
       beneficial ownership interest in the Global Notes or for maintaining,
       supervising or reviewing any of the DTC's records or any Participant's or
       Indirect Participant's records relating to the beneficial ownership
       interests in the Global Notes; or

    (3) any other matter relating to the actions and practices of the DTC or any
       of its Participants or Indirect Participants.

    The DTC has advised PRIMEDIA that its current practice, upon receipt of any
payment in respect of securities, such as the notes (including principal and
interest), is to credit the accounts of the relevant Participants with the
payment on the payment date unless the DTC has reason to believe it will not
receive payment on that payment date. Each relevant Participant is credited with
an amount proportionate to its beneficial ownership of an interest in the
principal amount of the relevant security as shown on the records of the DTC.
Payments by the Participants and the Indirect Participants to the beneficial
owners of notes will be governed by standing instructions and customary
practices and will be the responsibility of the Participants or the Indirect
Participants and will not be the responsibility of the DTC, the trustee or
PRIMEDIA. Neither PRIMEDIA nor the trustee will be liable for any delay by the
DTC or any of its Participants in identifying the beneficial owners of the
notes, and PRIMEDIA and the trustee may conclusively rely on and will be
protected in relying on instructions from the DTC or its nominee for all
purposes.

    Transfers between Participants in the DTC will be effected in accordance
with the DTC's procedures, and will be settled in same-day funds.

    The DTC has advised PRIMEDIA that it will take any action permitted to be
taken by a holder of notes only at the direction of one or more Participants to
whose account the DTC has credited the

                                       61
<Page>
interests in the Global Notes and only in respect of such portion of the
aggregate principal amount of the notes as to which the Participant or
Participants has or have given that direction. However, if there is an Event of
Default under the notes, the DTC reserves the right to exchange the Global Notes
for legended notes in certificated form and to distribute those notes to its
Participants.

    Although the DTC has agreed to the foregoing procedures to facilitate
transfers of interests in the Global Notes among participants in the DTC, they
are under no obligation to perform or to continue to perform such procedures,
and may discontinue such procedures at any time. Neither PRIMEDIA nor the
trustee nor any of their respective agents will have any responsibility for the
performance by the DTC or their respective participants or indirect participants
of their respective obligations under the rules and procedures governing their
operations.

EXCHANGE OF GLOBAL NOTES FOR CERTIFICATED NOTES

    A Global Note is exchangeable for definitive notes in registered
certificated form ("Certificated Notes") if:

    (1) the DTC (a) notifies PRIMEDIA that it is unwilling or unable to continue
       as depositary for the Global Notes and PRIMEDIA fails to appoint a
       successor depositary or (b) has ceased to be a clearing agency registered
       under the Exchange Act;

    (2) PRIMEDIA, at its option, notifies the trustee in writing that it elects
       to cause the issuance of the Certificated Notes; or

    (3) there has occurred and is continuing a Default or Event of Default with
       respect to the notes.

    In addition, beneficial interests in a Global Note may be exchanged for
Certificated Notes upon prior written notice given to the trustee by or on
behalf of the DTC in accordance with the indenture. In all cases, Certificated
Notes delivered in exchange for any Global Note or beneficial interests in
Global Notes will be registered in the names, and issued in any approved
denominations, requested by or on behalf of the depositary (in accordance with
its customary procedures).

SAME-DAY SETTLEMENT AND PAYMENT

    PRIMEDIA will make payments in respect of the notes represented by the
Global Notes (including principal, premium, if any, interest and liquidated
damages, if any) by wire transfer of immediately available funds to the accounts
specified by the Global Note Holder. PRIMEDIA will make all payments of
principal, interest and premium and liquidated damages, if any, with respect to
Certificated Notes by wire transfer of immediately available funds to the
accounts specified by the holders of the Certificated Notes or, if no such
account is specified, by mailing a check to each such holder's registered
address.

         net income is not at the date of determination permitted without any
         prior governmental approval (that has not been obtained) or, directly
         or indirectly, by operation of the terms of its charter or any
         agreement, instrument, judgment, decree, order, statute, rule or
         governmental regulation applicable to that Subsidiary or its
         stockholders that, in each such case, has not been legally waived or
         otherwise satisfied.

    In addition, "Consolidated Net Income" will not include, without limitation:

             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

    The following is a summary of certain U.S. federal income tax consequences
of the acquisition, ownership and disposition of new notes as of the date of
this prospectus. Except where noted, this summary deals only with new notes that
are acquired in connection with this exchange offer and held as capital assets
and does not deal with taxpayers subject to special treatment under the U.S.
federal income tax laws, including if you are one of the following:

    - a dealer in securities or currencies;

    - a financial institution;

    - an insurance company;

    - a tax exempt organization;

    - a person holding the new notes as part of a hedging, integrated or
      conversion transaction, a constructive sale or straddle;

    - a trader in securities that has elected the mark-to-market method of
      accounting for your securities;

    - a person liable for alternative minimum tax; or

    - a U.S. person whose "functional currency" is not the U.S. dollar.

    If a partnership holds the new notes, the tax treatment of a partner will
generally depend upon the status of the partner and the activities of the
partnership. If you are a partner of a partnership holding the new notes, you
should consult your own tax advisors.

    The discussion below is based upon the provisions of the Internal Revenue
Code of 1986, as amended, and regulations, rulings and judicial decisions as of
the date of this prospectus. Those authorities may be changed, perhaps
retroactively, so as to result in U.S. federal income tax consequences different
from those discussed below.

    IF YOU ARE CONSIDERING THE ACQUISITION OF NEW NOTES, YOU SHOULD CONSULT YOUR
OWN TAX ADVISORS CONCERNING THE FEDERAL INCOME TAX CONSEQUENCES TO YOU AND ANY
CONSEQUENCES ARISING UNDER THE LAWS OF ANY FOREIGN, STATE, LOCAL OR OTHER TAXING
JURISDICTION.

CONSEQUENCES OF THE EXCHANGE

    The exchange of the old notes for the new notes in the exchange offer (see
"The Exchange Offer") will not constitute a taxable event to you. As a result:

    - you will not realize any gain or loss upon receipt of a new note;

    - the holding period of the new note will include the holding period of the
      old note exchanged for the new note; and

    - the adjusted basis of the new note will be the same as the adjusted tax
      basis of the old note exchanged for the new note immediately before the
      exchange.

CONSEQUENCES TO U.S. HOLDERS

    The following is a summary of certain U.S. federal tax consequences that
will apply to you if you are a U.S. holder of new notes.

    The material consequences to "non-U.S. holders" of new notes, who are
beneficial owners of exchange notes and who are not U.S. holders, are described
below under "Consequences to Non-U.S. Holders".

                                       76
<Page>
    "U.S. holder" means a beneficial owner of a new note that is:

    - a citizen or resident of the United States;

    - a corporation or partnership created or organized in or under the laws of
      the United States or any political subdivision of the U.S.;

    - an estate the income of which is subject to U.S. federal income taxation
      regardless of its source; or

    - a trust that (1) is subject to the primary supervision of a court within
      the United States and the control of one or more U.S. persons or (2) has a
      valid election in effect under applicable U.S. Treasury regulations to be
      treated as a U.S. person.

    PAYMENTS OF INTEREST

    Except as set forth below, interest on a new note will generally be taxable
to you as ordinary income from domestic sources at the time it is paid or
accrued in accordance with your method of accounting for tax purposes.

    AMORTIZABLE BOND PREMIUM

    If you purchased an old note for an amount in excess of the sum of all
amounts payable on the old note after the purchase date other than stated
interest, you will be considered to have purchased the note at a "premium." You
generally may elect to amortize the premium over the remaining term (or an
applicable call date as discussed below) of the new note on a constant yield
method as an offset to interest when includible in income under your regular
method of accounting. The new notes are subject to a call provision at the
option of PRIMEDIA at various times, as described in this prospectus under
"Description of New Notes--Optional Redemption." You will calculate the amount
of amortizable bond premium based on the amount payable at the applicable call
date, but only if use of the call date (in lieu of the stated maturity date)
results in a smaller amortizable bond premium for the period ending on the call
date. If you do not elect to amortize bond premium, that premium will decrease
the gain or increase the loss you would otherwise recognize on disposition of
the new note. Your election to amortize premium on a constant yield method will
also apply to all debt obligations held or subsequently acquired by you on or
after the first day of the first taxable year to which the election applies. You
may not revoke the election without the consent of the Internal Revenue Service.
You should consult your own tax advisor before making this election.

    CALCULATION OF AMORTIZABLE BOND PREMIUM IS COMPLICATED, AND WE URGE YOU TO
CONSULT YOUR OWN TAX ADVISOR CONCERNING THE APPLICATION OF THESE RULES AS THEY
APPLY TO YOU.

    MARKET DISCOUNT

    If you purchased an old note for an amount that is less than its stated
redemption price at maturity, the amount will be treated as "market discount"
for United States federal income tax purposes, unless that difference is less
than a specified de minimis amount. Under the market discount rules, you will be
required to treat any payment, other than stated interest, on, or any gain on
the sale, exchange, retirement or other disposition of, a new note as ordinary
income to the extent of the market discount that you have not previously
included in income and are treated as having accrued on the new note at the time
of its payment or disposition. In addition, you may be required to defer, until
the maturity of the new note or its earlier disposition in a taxable
transaction, the deduction of all or a portion of the interest expense on any
indebtedness attributable to the new note.

    Any market discount will be considered to accrue ratably during the period
from the date of acquisition to the maturity date of the new note, unless you
elect to accrue on a constant yield interest

                                       77
<Page>
method. You may elect to include market discount in income currently as it
accrues, on either a ratable or constant yield interest method, in which case
the rule described above regarding deferral of interest deductions will not
apply. Your election to include market discount in income currently, once made,
applies to all market discount obligations acquired by you on or after the first
taxable year to which your election applies and may not be revoked without the
consent of the Internal Revenue Service. You should consult your own tax advisor
before making this election.

    SALE, EXCHANGE AND RETIREMENT OF NOTES

    When you sell, exchange or retire a new note, you will recognize gain or
loss equal to the difference between the amount you receive (less an amount
equal to any accrued interest you have not previously included in income, which
will be taxable as interest income) and your adjusted basis in the new note.
Except as described above with respect to market discount, your gain or loss
realized on the sale, exchange or retirement of a new note will generally be
treated as capital gain or loss, and will be long-term capital gain or loss if
at the time of the sale, exchange or retirement of a new note, you have held the
new note for more than one year. Long-term capital gains of individuals are
eligible for reduced rates of taxation. The deductability of capital losses is
subject to limitations.

INFORMATION REPORTING AND BACKUP WITHHOLDING

    In general, information reporting requirements will apply to certain
payments of principal, interest and premium paid on new notes and to the
proceeds of sale of a new notes made to you, unless you are an exempt recipient,
like a corporation. A backup withholding tax will apply to those payments if you
fail to provide a taxpayer identification number, a certification of exempt
status, or fail to report in full dividend and interest income.

CONSEQUENCES TO NON-U.S. HOLDERS

    The following is a summary of certain U.S. federal income tax consequences
that will apply to you if you are a non-U.S. holder of new notes. This summary
does not represent a detailed description of the federal income tax consequences
to you in light of your particular circumstances. In addition, it does not deal
with non-U.S. holders that are subject to special treatment under the U.S.
federal income tax laws (including if you are a controlled foreign corporation,
passive foreign investment company, foreign personal holding company, a
corporation that accumulates earnings to avoid federal income tax, or in certain
circumstances, a United States expatriate).

    U.S. FEDERAL WITHHOLDING TAX

    The 30% U.S. federal withholding tax will not apply to any payment of
principal or interest on the new notes provided that:

    - you do not actually, or constructively, own 10% or more of the total
      combined voting power of all classes of our voting stock within the
      meaning of the Internal Revenue Code and applicable U.S. Treasury
      regulations;

    - you are not a controlled foreign corporation that is related to us through
      stock ownership;

    - you are not a bank whose receipt of interest on the exchange notes is
      described in section 881(c)(3)(A) of the Internal Revenue Code; and

    - (a) you provide your name and address on an Internal Revenue Service Form
      W-BEN (or other applicable form), and certify, under penalties of perjury,
      that you are not a U.S. person or (b) you hold the exchange notes through
      certain foreign intermediaries and you satisfy the certification
      requirements of applicable U.S. Treasury regulations. Special
      certification rules apply to certain non-U.S. holders that are entities
      rather than individuals.

                                       78
<Page>
    If you cannot satisfy the requirements described above, payments of interest
made to you will be subject to the 30% U.S. federal withholding tax, unless you
provide us with a properly executed (1) Internal Revenue Service Form W-8BEN (or
other applicable form) claiming an exemption from, or reduction in, withholding
under the benefit of an applicable tax treaty; or (2) Internal Revenue Service
Form W-8ECI (or successor form) stating that interest paid on a new note is not
subject to withholding because it is effectively connected with your conduct of
a trade or business in the United States, as described below under "U.S. Federal
Income Tax".

    The 30% U.S. federal withholding tax will not generally apply to any gain
that you realize on the sale, exchange, retirement or other disposition of the
new notes.

    U.S. FEDERAL ESTATE TAX

    Your estate will not be subject to U.S. federal estate tax on new notes
beneficially owned by you at the time of your death, provided that you are not a
U.S. citizen or resident (as specifically defined for U.S. federal estate tax
purposes) and (1) you do not own 10% or more of the total combined voting power
of all classes of our voting stock (within the meaning of the Internal Revenue
Code and the U.S. Treasury regulations) and (2) interest on the new note would
not have been, if received at the time of your death, effectively connected with
the conduct by you of a trade or business in the United States.

    U.S. FEDERAL INCOME TAX

    If you are engaged in a trade or business in the United States and interest
on the new notes is effectively connected with the conduct of that trade or
business, you will be subject to U.S. Federal income tax on that interest on a
net income basis in the same manner as if you were a U.S. person as defined
under the Internal Revenue Code, although that interest income will be exempt
from the 30% U.S. federal withholding tax. In addition, if you are a foreign
corporation, you may be subject to a branch profits tax equal to 30% (or lower
applicable treaty rate) of your earnings and profits for the taxable year,
subject to certain adjustments.

    Any gain realized on the disposition of a new note generally will not be
subject to U.S. federal income tax unless:

    - the gain is effectively connected with the conduct by you of a trade or
      business in the United States, or

    - you are an individual who is present in the United States for 183 days or
      more in the taxable year of that disposition, and other conditions are
      met.

    INFORMATION REPORTING AND BACKUP WITHHOLDING

    In general, you will not be subject to backup withholding and information
reporting with respect to payments that we make to you provided that we do not
have actual knowledge that you are a U.S. person and we have received from you
the statement described above under "Consequences to Non-U.S. Holders--U.S.
Federal Withholding Tax."

    In addition, you will not be subject to backup withholding or information
reporting with respect to the proceeds of the sale of a new note within the
United States or conducted through U.S.-related financial intermediaries, if the
payor receives the statement described above and does not have actual knowledge
that you are a U.S. person, as defined under the Internal Revenue Code, or you
otherwise establish an exemption.

                              PLAN OF DISTRIBUTION

    Each broker-dealer that receives new notes for its own account pursuant to
the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of the new notes. This prospectus, as it may be
amended or supplemented, may be used by a broker-dealer in connection with
resales of new notes received in exchange for old notes only where the old notes
were acquired as a result of market-making activities or other trading
activities. We have agreed that we will make this prospectus, as amended or
supplemented, available to any broker-dealer for use in connection with any
resale for a period of 180 days from the date on which the exchange offer is
consummated, or any shorter period as will terminate when all old notes acquired
by broker-dealers for their own accounts as a result of market-making activities
or other trading activities have been exchanged for new notes and the new notes
have been resold by the broker-dealers.

    We will not receive any proceeds from any sale of new notes by
broker-dealers. New notes received by broker-dealers for their own account
pursuant to the exchange offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the new notes or a combination of these methods of
resale, at market prices prevailing at the time of resale, at prices related to
the prevailing market prices or negotiated prices. Any resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any broker-dealer or
the purchasers of any new notes. Any broker-dealer that resells new notes that
were received by it for its own account pursuant to the exchange offer and any
broker or dealer that participates in a distribution of the new notes may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit on any resale of new notes and any commissions or concessions received by
these persons may be deemed to be underwriting compensation under the Securities
Act. The letter of transmittal states that by acknowledging that it will deliver
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act.

    For a period of 180 days from the date on which the exchange offer is
consummated, or a shorter period as will terminate when all old notes acquired
by broker-dealers for their own accounts as a result of market-making activities
or other trading activities have been exchanged for new notes and the new notes
have been resold by the broker-dealers, we will promptly send additional copies
of this prospectus and any amendment or supplement to this prospectus to any
broker-dealer that requests the documents in the letter of transmittal. We have
agreed to pay all expenses incident to the exchange offer, including the
expenses of one counsel for the holders of the old notes, other than commissions
or concessions of any brokers or dealers and the fees of any counsel or other
advisors or experts retained by the holders of old notes, except as expressly
set forth in the registration rights agreement, and will indemnify the holders
of old notes, including any broker-dealers, against certain liabilities,
including liabilities under the Securities Act.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    (a) PRIMEDIA Inc., Adams/Laux Company, Inc., Bacon's Information, Inc.,
Canoe & Kayak, Inc., Channel One Communications Corp., Climbing, Inc., CSK
Publishing Company Inc., ENO Productions, Inc., Films for the Humanities &

PRIMEDIA Special Interest Publications Inc.

    Reference is made to Section 102(b)(7) of the Delaware General Corporation
Law (the "DGCL") which enables a corporation in its original certificate of
incorporation or an amendment thereto to eliminate or limit the personal
liability of a director for violations of the director's fiduciary duty, except
(i) for any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) for liability of
directors for unlawful payment of dividends or unlawful stock purchase or
redemptions pursuant to Section 174 of the DGCL or (iv) for any transaction from
which a director derived an improper personal benefit.

    Reference also is made to Section 145 of the DGCL, which provides that a
corporation may indemnify any persons, including officers and directors, who
are, or are threatened to be made, parties to any threatened, pending or
completed legal action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of such
corporation), by reason of the fact that such person was an officer, director,
employee or agent of such corporation or is or was serving at the request of
such corporation as a director, officer, employee or agent of another
corporation or enterprise. The indemnity may include expenses (including
attorney's fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding, provided such officer, director, employee or agent acted in good
faith and in a manner he reasonably believed to be in or not opposed to the
corporation's best interest and, for criminal proceedings, had no reasonable
cause to believe that his conduct was unlawful. A Delaware corporation may
indemnify officers and directors in an action by or in the right of the
corporation under the same conditions, except that no indemnification is
permitted without judicial approval if the officer or director is adjudged to be
liable to the corporation. Where an officer or director is successful on the
merits or otherwise in the defense of any action referred to above, the
corporation must indemnify him against the expenses that such officer or
director actually and reasonably incurred.

    (c) Bowhunter Magazine, Inc. and PRIMEDIA Enthusiast Publications, Inc.

    Subchapter D of Chapter 17 of the Pennsylvania Business Corporation Law of
1988 (the "PBCL" or "Pennsylvania Law") contains provisions for mandatory and
discretionary indemnification of a corporation's directors, officers, employees
and agents, and related matters, which are summarized below.

    Under Section 1741, subject to certain limitations, a corporation has the
power to indemnify directors, officers and other parties under certain
prescribed circumstances against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
in connection with a threatened, pending or completed action or proceeding,
whether civil, criminal, administrative or investigative, to which any of them
is a party or threatened to be made a party by reason of his being a
representative of the corporation or serving at the request of the corporation
as a representative of another corporation, partnership, joint venture, trust or
other enterprise, if he acted in good faith and in a manner he reasonably
believed to be in, or not opposed to, the best interests of the corporation and,
with respect to any criminal proceeding, had no reasonable cause to believe his
conduct was unlawful.

    Section 1742 provides for indemnification with respect to derivative actions
similar to that provided by Section 1741. However, indemnification is not
provided under Section 1742 in respect of any claim, issue or matter as to which
a party has been adjudged to be liable to the corporation unless and only to the
extent that the proper court determines upon application that, despite the
adjudication of liability

                                      II-2
<Page>
but in view of all the circumstances of the case, the party is fairly and
reasonably entitled to indemnity for the expenses that the court deems proper.

    Section 1743 provides that indemnification against expenses is mandatory to
the extent that a party has been successful on the merits or otherwise in
defense of any such action or proceeding referred to in Section 1741 or 1742.

    Section 1744 provides that unless ordered by a court, any indemnification
under Section 1741 or 1742 shall be made by the corporation as authorized in the
specific case upon a determination that indemnification of a party is proper
because the party met the applicable standard of conduct, and such determination
will be made by (i) the board of directors by a majority vote of a quorum of
directors not parties to the action or proceeding; (ii) if a quorum is not
obtainable or if obtainable and a majority of disinterested directors so
directs, by independent legal counsel in a written opinion; or (iii) by the
shareholders.

    Section 1745 provides that expenses incurred by a parties in defending any
action or proceeding referred to in Subchapter D of Chapter 17 of the PBCL may
be paid by the corporation in advance of the final disposition of such action or
proceeding upon receipt of an undertaking by or on behalf of the party to repay
such amount if it shall ultimately be determined that he is not entitled to be
indemnified by the corporation.

    Section 1746 provides generally that except in any case where the act or
failure to act giving rise to the claim for indemnification is determined by a
court to have constituted willful misconduct or recklessness, the
indemnification and advancement of expenses provided by Subchapter D of Chapter
17 of the PBCL shall not be deemed exclusive of any other rights to which a
Representative seeking indemnification or advancement of expenses may be
entitled under any bylaw, agreement, vote of shareholders or disinterested
directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding that office.

    The by-laws of Bowhunter Magazine, Inc. and PRIMEDIA Enthusiast
Publications, Inc. provide that, to the fullest extent permitted by the PBCL, as
amended from time to time, will indemnify any and current or former directors or
officers, and may indemnify any current or former employee or agents, from and
against any and all of the expenses, liabilities, or other matters referred to
in the PBCL.

    (d) Communication Concepts, Inc.

    Subsection 1 of Section 78.7502 of the Nevada General Corporation Law (the
"NGCL") empowers a corporation to indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit, or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.

    Subsection 2 of Section 78.7502 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above against expenses,
including amounts paid in settlement and attorneys' fees actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted under similar standards, except that no indemnification

                                      II-3
<Page>
may be made in respect of any claim, issue or matter as to which such person
shall have been adjudged by a court of competent jurisdiction to be liable to
the corporation or for amounts paid in settlement to the corporation, unless and
only to the extent that the court in which such action or suit was brought
determines that, despite the adjudication of liability, such person is fairly
and reasonably entitled to indemnity for such expenses as the court deems
proper.

    Section 78.7502 further provides that to the extent a director or officer of
a corporation has been successful in the defense of any action, suit or
proceeding referred to in subsections (1) and (2), or in the defense of the
claim, issue or matter, he shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by him. Section 78.751 of the
NGCL provides that the indemnification provided for by Section 78.7502 shall not
be deemed exclusive or exclude any other rights to which the indemnified party
may be entitled and that the scope of indemnification shall continue as to
directors, officers, employees or agents who have ceased to hold such positions,
and to their heirs, executors and administrators.

    Article VI of the Articles of Incorporation of Communication Concepts, Inc.
provides that, to the fullest extent permitted by the NGCL, as amended from time
to time, the company will indemnify its directors from and against any and all
of the expense, liabilities or other matters referred to in the NGCL.
Article VI further provides that a director shall not be liable for damages for
actions of the corporation to stockholder or to any other person (natural or
otherwise) unless such director engages in personal fraud affecting such action
or actions of the corporation.

    (e) Cowles History Group, Inc.

    Cowles History Group, Inc. is permitted by sections 13.1-697 and 13.1-702 of
the Virginia Stock Corporation Act ("VSCA"), subject to the procedures and
limitations stated therein and in section 13.1-701, to indemnify directors,
officers, employees, and agents in civil or criminal actions if they acted in
good faith and believed their conduct to be in the best interests of the
corporation and, in the case of criminal actions, had no reasonable cause to
believe that the conduct was unlawful.

    Article X of Cowles History Group, Inc.'s Articles of Incorporation states
that no director shall be personally liable to the corporation or its
shareholders for monetary damages for breach of fiduciary duty to the extent
allowable by the VSCA provided that (1) the director did not breach his duty of
loyalty to the corporation or its shareholders, (2) the director did not act in
good faith or knowingly violated the law, or (3) the director did not derive an
improper personal benefit from his actions.

    (f) Symbol of Excellence Publishers, Inc.

    Sections 10-2B-8.51 and 10-2B-8.56 of the Code of Alabama gives a
corporation power to indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, against
expenses (including attorneys' fees), judgments, penalties, fines and amounts
paid in settlement reasonably incurred by him in connection with such action,
suit or proceeding. Indemnification is only allowed if the person acted in good
faith and in a manner he reasonably believed to be in the best interests of the
corporation, when acting in his or her official capacity with the corporation,
or, in all other cases, not opposed to the best interests of the corporation,
and, with respect to any criminal action or proceeding, had no reasonable cause
to believe his conduct was unlawful.

    The same sections also give a corporation power to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding by or in the right of the corporation,
against expenses (including attorneys' fees) reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in the best interests of
the corporation, when acting in his or her official capacity with the
corporation or, in all other cases, not opposed to the best interests of the
corporation. No indemnification shall be made, however, in respect of any claim,
issue or matter as to

                                      II-4
<Page>
which such person shall have not met the applicable standard of conduct, shall
have been adjudged to be liable to the corporation or, in connection with any
other action, suit or proceeding charging improper personal benefit to such
person, if such person was adjudged liable on the basis that personal benefit
was improperly received by him, unless and only to the extent that the court in
which such action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, the person is fairly and reasonably entitled to indemnity for expenses
which the court shall deem proper.

    Section 10-2B-8.52 further states that, to the extent that a director,
officer, employee or agent of a corporation has been successful on the merits or
otherwise in defense of any such action, suit or proceeding, or in defense of
any claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) reasonably incurred by him in connection therewith,
notwithstanding that he has not been successful on any other claim, issue or
matter in any such action, suit or proceeding.

    As permitted by the Code of Alabama, the by-laws of Symbol of Excellence
Publishers, Inc. provide that, to the fullest extent permitted by the Code of
Alabama, as amended from time to time, the company will indemnify any and
current or former directors or officers, and may indemnify any current or former
employee or agents, from and against any and all of the expenses, liabilities,
or other matters referred to in the Code of Alabama.

    (g) The Virtual Flyshop, Inc.

    Article 7-109 of the Colorado Business Corporation Act ("CBCA") authorizes
the indemnification of directors and officers against liability incurred by
reason of being a director or officer and against expenses (including attorney's
fees), judgments, fines and amounts paid in settlement and reasonably incurred
in connection with any action seeking to establish liability. In the case of
third-party claims, if the officer or director acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the corporation, and in the case of actions by or in the right of the
corporation, if the officer or director acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and if the officer or director shall not have been adjudged liable
to the corporation, the CBCA authorizes indemnification unless a court otherwise
determines that this would contravene public policy. Indemnification is also
authorized with respect to any criminal action or proceeding where the officer
or director also had no reasonable cause to believe his conduct was unlawful.

    As permitted by the CBCA, Article VII(c) of the Articles of Incorporation
and the by-laws of The Virtual Flyshop, Inc. provide that, to the fullest extent
permitted by the CBCA, as amended from time to time, the company will indemnify
any and current or former directors or officers, and may indemnify any current
or former employee or agents, from and against any and all of the expenses,
liabilities, or other matters referred to in the CBCA.

    (h) Go Lo Entertainment, Inc., Horse & Rider, Inc., IntelliChoice, Inc.,
Kagan Media Appraisals, Inc., Kagan Seminars, Inc., Low Rider Publishing
Group, Inc., McMullen Argus Publishing, Inc. and Miramar Communications, Inc.

    Section 317 of the California General Corporations Law ("CGCL") authorizes a
court to award, or a corporation's board of directors to grant, indemnity to
directors and officers who are parties or are threatened to be made parties to
any proceeding (with certain exceptions) by reason of the fact that the person
is or was an agent of the corporation, against expenses, judgments, fines,
settlements and other amounts actually and reasonably incurred in connection
with the proceeding if that person acted in good faith and in a manner the
person reasonably believed to be in the best interests of the corporation.
Section 317 of the CGCL does not extend to acts or omissions of a director in
his capacity as an officer. Further, section 317 has no effect on claims arising
under federal or state securities laws and does not affect the availability of
injunctions and other equitable remedies available to its shareholders for any
violation of a director's fiduciary duty to the corporation or its shareholders.

                                      II-5
<Page>
    Section 204 of the CGCL provides that the limitation on liability in
section 317 has no effect on a director's liability (a) for acts or omissions
that involve intentional misconduct or a knowing and culpable violation of law,
(b) for acts or omissions that a director believes to be contrary to the best
interests of the corporation or its shareholders or that involve the absence of
good faith on the part of the director, (c) for any transaction from which a
director derived an improper personal benefit, (d) for acts or omissions that
show a reckless disregard for the director's duty to the corporation or its
shareholders in circumstances in which the director was aware, or should have
been aware, in the ordinary course of performing a director's duties, of a risk
of a serious injury to the corporation or its shareholders, (e) for acts or
omissions that constitute an unexcused pattern of inattention that amounts to an
abdication of the director's duty to the corporation or its shareholders,
(f) under Section 310 of the law (concerning contracts or transactions between
the corporation and a director), or (g) under Section 316 of the law (directors'
liability for improper dividends, loans and guarantees).

    The certificate of incorporations and/or bylaws of Go Lo
Entertainment, Inc., Horse & Rider, Inc., IntelliChoice, Inc., Low Rider
Publishing Group, Inc. and McMullen Argus Publishing, Inc. provide for the
mandatory indemnification of their directors and officers, and the discretionary
indemnification of their employees and other agents, to the maximum extent
permitted by the CGCL. The certification of incorporation and by-laws of Miramar
Communications, Inc. do not have such a provision, but the board of directors
may still indemnify directors pursuant to the CGCL.

(i) Simba Information, Inc.

    Section 33-771 of the Connecticut Stock Corporation Act ("CSCA") authorizes
a corporation to indemnify a director who is sued in his official capacity as
long as (1) he conducted himself in good faith and (2) he reasonably believed
that his official conduct was in the best interests of the corporation or that
his conduct was not opposed to the best interests of the corporation.
Indemnification is also available in the case of a criminal proceeding if the
director had no reasonable cause to believe that his conduct was unlawful.
Section 33-772 mandates that a corporation indemnify against reasonable expenses
incurred by a director who is wholly successful, on the merits or otherwise, in
defense of any proceeding to which he was a party because of his position as a
director of the corporation. Section 33-779 of the CSCA limits the provision of
indemnification solely to the conditions as specified by the CSCA.

    Section 33-778 of the CSCA provides that a corporation may obligate itself
in advance to provide indemnification according to the requirements of
Section 33-771 by a provision in its certificate of incorporation or by-laws or
in a resolution approved by the board of directors or shareholders. Simba
Information, Inc. contains such a provision in Article V of its by-laws, which
states that the corporation will be bound and comply with the provisions of the
CSCA pertaining to indemnification of corporate shareholders, officers,
directors, employees, agents, and other eligible parties.

ITEM 22. UNDERTAKINGS

    The undersigned registrants hereby undertake:

        (1) To file, during any period in which offers or sales of the
    registered securities are being made, a post-effective amendment to this
    registration statement;

         (i) To include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;

         (ii) To reflect in the prospectus any facts or events arising after the
     effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in he information set forth in the
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in the volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low and high and of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than 20 percent change in the maximum aggregate
     offering price set forth in the "Calculation of Registration Fee" table in
     the effective registration statement; and

         (iii) To include any material information with respect to the plan
     distribution not previously disclosed in the registration statement or any
     material change in such information in the registration statement.

        (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial BONA FIDE offering thereof.

        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.

        (4) That, for purposes of determining any liability under the Securities
    Act of 1933, each filing of the registrant's annual report pursuant to
    section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and,
    where applicable, each filing of an employee benefit plan's annual report
    pursuant to section 15(d) of the Securities Exchange Act of 1934) that is
    incorporated by reference in the registration statement shall be deemed to
    be a new registration statement relating to the securities offered therein,
    and the offering of such securities at that time shall be deemed to be the
    initial bona fide offering thereof.

        (5) To respond to requests for information that is incorporated by
    reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this
    form, within one business day of receipt of such request, and to send the
    incorporated documents by first class mail or other equally prompt means.
    This includes information contained in documents filed subsequent to the
    effective date of the registration statement through the date of responding
    to the request.

        (6) To supply by means of a post-effective amendment all information
    concerning a transaction, and the company being acquired involved therein,
    that was not the subject of and included in the registration statement when
    it became effective.

                                      II-8

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions or otherwise, the registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer of controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
