  OFFER TO EXCHANGE ITS 9 1/4% SENIOR SUBORDINATED NOTES DUE 2008, WHICH HAVE
 BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, FOR ANY AND ALL
  OF ITS OUTSTANDING 9 1/4% SENIOR SUBORDINATED NOTES DUE 2008, WHICH HAVE NOT
                               BEEN SO REGISTERED
 
                                  ----------
 THE EXCHANGE OFFER AND WITHDRAWAL RIGHTS THEREUNDER WILL EXPIRE AT 5:00 P.M.,
          NEW YORK CITY TIME, ON             , 1998, UNLESS EXTENDED.
 
                                  ----------
  Advanstar Communications Inc., a New York corporation ("Advanstar" or the
"Company"), a wholly-owned subsidiary of Advanstar Holdings, Inc., a Delaware
corporation ("Holdings"), hereby offers (the "Exchange Offer"), upon the terms
and conditions set forth in this Prospectus (the "Prospectus") and the
accompanying Letter of Transmittal (the "Letter of Transmittal"), to exchange
an aggregate principal amount of up to $150,000,000 of its 9 1/4% Senior
Subordinated Notes due 2008 (the "Exchange Notes"), which have been registered
under the Securities Act of 1933, as amended (the "Securities Act"), pursuant
to a Registration Statement of which this Prospectus is a part, for a like
principal amount of its outstanding 9 1/4% Senior Subordinated Notes due 2008
(the "Original Notes", and, together with the Exchange Notes, the "Notes"),
which have not been so registered, from the holders thereof. The form and terms
of the Exchange Notes are the same as the form and terms of the Original Notes
(which they replace), except that as of the date hereof the Exchange Notes have
been registered under the Securities Act and, therefore, will not bear legends
restricting their transfer and will not contain certain provisions included in
the terms of the Original Notes relating to an increase in the interest rate in
certain circumstances relating to the timing of the Exchange Offer. The
Exchange Notes will evidence the same debt as the Original Notes (which they
replace) and will be issued under and be entitled to the benefits of the
Indenture, dated as of April 30, 1998 (the "Indenture"), between the Company
and The Bank of New York, as trustee (the "Trustee"), which also governs the
Original Notes. See "The Exchange Offer" and "Description of Notes."
 
  The Company will accept for exchange any and all Original Notes duly tendered
and not validly withdrawn prior to 5:00 p.m., New York City time, on        ,
1998, unless extended by the Company in its sole discretion (the "Expiration
Date"). Tenders of Original Notes may be withdrawn at any time prior to 5:00
p.m., New York City time on the Expiration Date. The Exchange Offer is not
conditioned upon any minimum principal amount of Original Notes being tendered
for exchange pursuant to the Exchange Offer, but is subject to certain
customary conditions.
 
  The Original Notes were sold by the Company on April 30, 1998 to Chase
Securities Inc. and Lehman Brothers Inc. (collectively, the "Initial
Purchasers") in connection with the acquisition (the "MAGIC Acquisition") by
Advanstar of Men's Apparel Guild in California, Inc. ("MAGIC") and certain
refinancing transactions. See "The Acquisitions and Refinancing." The Original
Notes were sold by the Company to the Initial Purchasers in transactions not
registered under the Securities Act in reliance upon an exemption from
registration under the Securities Act (the "Offering"). The Initial Purchasers
subsequently resold the Original Notes in the United States to qualified
institutional buyers in reliance upon Rule 144A under the Securities Act ("Rule
144A") and outside the United States in accordance with Regulation S under the
Securities Act. The Exchange Notes are being offered hereunder in order to
satisfy certain obligations of the Company contained in the Exchange and
Registration Rights Agreement dated April 30, 1998 among the Company and the
other signatories thereto (the "Registration Rights Agreement").
 
  The Company believes that, based on interpretations by the staff of the
Securities and Exchange Commission (the "Commission"), Exchange Notes issued
pursuant to the Exchange Offer in exchange for Original Notes may be offered
for resale, resold and otherwise transferred by each holder thereof (other than
any such holder which is an "affiliate" of the Company 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 such
Exchange Notes are acquired in the ordinary course of such holder's business
and such holder has no arrangement with any person to participate in the
distribution of such Exchange Notes. Each broker-dealer that receives Exchange
Notes for its own account pursuant to the Exchange Offer must acknowledge that
it will deliver a prospectus in connection with any resale of such Exchange
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. The Company has
agreed that, for a period of 180 days after the Expiration Date (as defined),
it will make this Prospecuts available to any broker-dealer for use in
connection with certain resales. See "Plan of Distribution." All resales must
be made in compliance with applicable state securities or "blue sky" laws. Such
compliance may require that the Exchange Notes be registered or qualified in a
particular state or that the resales be made by or through a licensed broker-
dealer, unless exemptions from these requirements are available. The Company
assumes no responsibility with regard to compliance with such requirements.

   SEE "RISK FACTORS" BEGINNING ON PAGE 19 HEREOF FOR A DISCUSSION OF CERTAIN
FACTORS THAT SHOULD BE CONSIDERED BY HOLDERS WHO TENDER THEIR ORIGINAL NOTES IN
                              THE EXCHANGE OFFER.
 
                                  ----------
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE COMMISSION OR ANY
   STATE SECURITIES COMMISSION NOR HAS THE COMMISSION OR ANY STATE SECURITIES
    COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
             REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
 
                                  ----------
                 The date of this Prospectus is         , 1998.

(Cover continued from previous page)
 
  Interest on the Notes is payable semi-annually on May 1 and November 1 of
each year, commencing on November 1, 1998. The Notes will mature on May 1,
2008. Except as described below, the Company may not redeem the Notes prior to
May 1, 2003. On or after such date, the Company may redeem the Notes, in whole
or in part, at any time at the redemption prices set forth herein, plus
accrued and unpaid interest thereon, if any, to the date of redemption. In
addition, at any time and from time to time prior to May 1, 2001, the Company
may, subject to certain requirements, redeem up to 35% of the original
aggregate principal amount of the Notes with the net cash proceeds of one or
more Equity Offerings (as defined) at a redemption price equal to 109.250% of
the principal amount thereof, plus accrued and unpaid interest thereon, if
any, to the date of redemption; provided, however, that at least 65% of the
original aggregate principal amount of the Notes remains outstanding
immediately after each such redemption. The Notes will not be subject to any
sinking fund requirements. Upon the occurrence of a Change of Control (as
defined), the Company will have the option, at any time prior to May 1, 2003,
to redeem the Notes, in whole but not in part, at a redemption price equal to
100% of the principal amount thereof plus the Applicable Premium (as defined),
together with accrued and unpaid interest, if any, to the date of redemption.
Upon the occurrence of a Change of Control, if the Company does not so redeem
such Notes or if a Change of Control occurs after May 1, 2003, the Company
will be required to make an offer to purchase the Notes at a price equal to
101% of the original aggregate principal amount thereof, together with accrued
and unpaid interest, if any, to the date of purchase. See "Description of
Notes."
 
  The Notes will be unsecured and will be subordinated in right of payment to
all existing and future Senior Indebtedness (as defined) of the Company. The
Notes will rank pari passu with all future Senior Subordinated Indebtedness
(as defined) of the Company and will rank senior to all future Subordinated
Obligations (as defined) of the Company. The Notes will be fully and
unconditionally guaranteed (the "Note Guarantees") on an unsecured, senior
subordinated basis by each of the Company's direct and indirect domestic
Restricted Subsidiaries (as defined) and by Holdings (collectively, the
"Guarantors"). The Indenture governing the Notes permits the Company and its
subsidiaries to incur additional indebtedness, including Senior Indebtedness,
subject to certain restrictions.
 
  The Exchange Offer is not being made to, nor will the Company accept
surrenders for exchange from, holders of Original Notes in any jurisdiction in
which such Exchange Offer or the acceptance thereof would not be in compliance
with the securities or blue sky laws of such jurisdiction. Holders of Original
Notes not tendered and accepted in the Exchange Offer will continue to hold
such Original Notes and will be entitled to all the rights and benefits and
will be subject to the limitations applicable thereto under the Indenture and
with respect to transfer under the Securities Act. Holders of Original Notes
not tendered in the Exchange Offer will not retain any rights under the
Registration Rights Agreement, except in limited circumstances. The Company
will pay all expenses incurred by it incident to the Exchange Offer. See "The
Exchange Offer."
 
  There has not previously been any public market for the Exchange Notes. The
Company does not intend to list the Exchange Notes on any securities exchange
or to seek approval for quotation through any automated quotation system.
There can be no assurance that an active market for the Exchange Notes will
develop. The Initial Purchasers have informed the Company that they currently
intend to make a market in the Exchange Notes, but are not obligated to do so
and any such market making may be discontinued at any time without notice. The
Initial Purchasers may act as principal or as agent in such transactions. If a
market for the exchange Notes should develop, the Exchange Notes could trade
at a discount from their principal amount. See "Risk Factors -- Absence of
Public Market." Moreover, to the extent that Original Notes are tendered and
accepted in the Exchange Offer, the trading market for untendered and tendered
but unaccepted Original Notes could be adversely affected.

                                  THE COMPANY
 
OVERVIEW
 
  The Company is a leading provider of global, multi-product marketing
communications solutions, principally through controlled circulation trade,
business and professional magazines and trade shows, expositions and
conferences. The Company also provides a broad range of other marketing
services products, including direct mail and database products and services.
The Company publishes 73 specialized business magazines and professional
journals and 30 directories and other publications. Of Advanstar's 55 magazines
and journals for which competitive data is available, over 75% rank either #1
or #2 in their respective markets (based on number of advertising pages). The
Company owns and manages 76 expositions and 29 conferences for business,
professional and consumer audiences worldwide, most of which are the leading
events in their respective national or regional markets. After giving effect to
the Pro Forma Adjustments, the Company would have derived 50.1% of its 1997
revenues from publishing, 44.3% from expositions and conferences and 5.6% from
marketing services. After giving effect to the Pro Forma Adjustments, (i) the
Company's 1997 revenue, EBITDA (as defined) and EBITDA margin would have been
$247.3 million, $56.0 million and 22.7%, respectively; and (ii) the Company's
revenue, EBITDA and EBITDA margin for the first quarter ended March 31, 1998
would have been $79.6 million, $23.6 million and 29.6%, respectively. EBITDA is
not a measure of performance defined by generally accepted accounting
principles ("GAAP") and should not be considered in isolation or as a
substitute for net income or the statement of cash flows which have been
prepared in accordance with GAAP.
 
  The Company markets its broad range of products and services primarily
through four industry clusters in which it has developed critical mass and
expertise: (i) Retail, Hospitality & Fashion; (ii) Healthcare & Pharmaceutical;
(iii) Information Technology & Communications; and (iv) Manufacturing &
Processing. The Company believes its industry-focused cluster structure allows
it to cross-sell its products effectively, thereby capturing a larger share of
customer marketing expenditures. These four clusters are further divided into
21 industry sectors. The Company has expanded its product line within its
clusters through new product introductions and strategic acquisitions. These
actions have enhanced the Company's position as a leading provider of
integrated business-to-business marketing communications solutions. In
addition, these actions have increased the Company's EBITDA by leveraging its
existing marketing and customer service infrastructure and industry expertise.
 
  On April 30, 1998, Advanstar acquired MAGIC. MAGIC, organized in 1933,

the largest women's apparel show in the United States; and MAGICKids, a
recently introduced children's apparel show. The three shows are held
concurrently in Las Vegas in February and August each year. The February 1998
shows occupied an aggregate of approximately 505,000 net square feet of
permanent floor space and 285,000 net square feet of temporary floor space at
the Las Vegas Convention Center and the Las Vegas Hilton. Commencing with the
August 1998 shows, the MAGIC trade shows will occupy approximately 700,000 net
square feet of permanent floor space at the Las Vegas Convention Center and
approximately 250,000 net square feet of permanent floor space at the Sands
Convention Center. The addition of the Sands Convention Center will eliminate
the need to use more costly temporary space and will allow MAGIC to partially
meet a long-standing backlog demand for exhibit space. The February 1998 MAGIC
trade shows attracted an audience of over 80,000 attendees from over 100
countries, including major retailers, such as Federated Department Stores,
Nieman Marcus, Nordstrom's and Wal-Mart. MAGIC's February 1998 trade shows
included over 3,200 exhibitors (such as Levi Strauss, Calvin Klein, Donna Karan
and the Russell Corporation), representing approximately 5,000 brand names.
MAGIC's February 1996 and August 1996 trade shows ranked, respectively, as the
12th and 11th largest trade shows in the United States. MAGIC's revenue, EBITDA
and EBITDA margin for its fiscal year ended May 31, 1997 were $31.2 million,
$12.2 million and 39.3%, respectively. For the nine months ended February 28,
1998, MAGIC's revenue, EBITDA and EBITDA margin were $38.7 million, $20.7
million and 53.5%, respectively, representing a revenue increase of 24.8% and
an EBITDA increase of 47.4% over the nine months ended February 28, 1997.
 
COMPETITIVE ADVANTAGES
 
  The Company believes that the following factors contribute to its strong
competitive position:
 
  Market Leadership. The Company has achieved a strong market position within
each of its four industry clusters primarily as a result of its ability to
offer customers in each cluster comprehensive and integrated marketing
communications solutions, consisting of leading publications, expositions and
marketing services. The Company publishes 73 specialized business magazines and
professional journals and 30 directories and other publications. Of Advanstar's
55 magazines and journals for which competitive data is available, over 75%
rank either #1 or #2 in their respective markets (based on number of
advertising pages). The Company's largest magazines include Video Store,
CADALYST, Pharmaceutical Technology and Hotel & Motel management. The Company
also owns and manages 76 trade shows and expositions and 29 conferences, most
of which are the leading events in their respective national or regional
markets. Many of the Company's expositions have commanding market presence: for
example, MAGIC is the #1 men's apparel trade show in the United States; IBS New
York is the #1 beauty show in the world; Telexpo is the #1 telecommunications
trade show in Latin America; Artexpo New York is the #1 mid-market art fair in
the United States; Dealernews International Powersports Dealer Expo is the #1
trade show for the motorcycle industry; Licensing International is the world's
leading event for the international merchandise licensing industry; and TeleCon
is the leading event for the video conference and long distance learning
markets.
 
  Industry--Focused Integrated Marketing. In addition to offering a broad range
of products, the Company has developed a business model focused on industry
clusters to better serve its customers' marketing communications needs. This
model facilitates the development of long-term relationships between customers
and dedicated Advanstar teams. These teams work with customers to design and to
implement all aspects of customized, business-to-business marketing and
communications programs, increasing cross-selling opportunities across product
and service groups. For example, the Company's call center group, which is part
of the Information Technology & Communications cluster, recently concluded
several multi-year marketing contracts involving participation in the Company's
trade shows and advertising in the Company's trade publications.
 
                                       2
<PAGE>
 
 
  Diverse Customer Base. The Company's diverse customer base provides it with
stable and diverse sources of revenue and cash flow as well as an established
foundation from which to further penetrate existing markets and to develop new
markets. The Company's customer base is geographically diverse and crosses many
disparate industries, mitigating the Company's exposure to downturns in
particular geographic markets or industries. After giving effect to the Pro
Forma Adjustments, in 1997 the Company had over 14,000 advertisers and
exhibitors operating in over 20 different industry sectors, with no customer or
industry sector representing more than 1.1% or 13.7% of revenue, respectively.
 
  Attractive EBITDA Margins and Modest Ongoing Capital Requirements. Consistent
with other leaders in the controlled circulation publication and trade show
industries, the Company enjoys attractive EBITDA margins and modest ongoing
capital expenditure requirements. The modest ongoing capital requirements
result in part from the Company's outsourcing of the printing of its trade
publications and the physical operation of its expositions. After giving effect
to the Pro Forma Adjustments, in 1997 the Company's operating cash flow
(defined as EBITDA, less capital expenditures) would have been $53.4 million,
or 21.6% of revenue. In 1997, the Company's capital expenditures were $2.6
million. After giving effect to the Pro Forma Adjustments, the Company's
operating cash flow for the first quarter ended March 31, 1998 would have been
$22.1 million, or 27.8% of revenue. The Company's capital expenditures for the
first quarter ended March 31, 1998 were $1.5 million.
 
  Experienced and Incentivized Management Team. The members of Advanstar's
senior management team have an average of over 15 years of industry experience,
with established track records in delivering revenue and profit growth,
developing new products, penetrating new markets and integrating acquisitions.
The Company's management is led by Robert L. Krakoff, Chairman and Chief
Executive Officer, James M. Alic, Vice Chairman and Ira T. Siegel, Vice
Chairman and Chief Operating Officer. Messrs. Krakoff and Alic joined Advanstar
in July 1996 and Mr. Siegel joined the Company in May 1998. Prior to joining
Advanstar, Mr. Krakoff was Chief Executive Officer of Cahners Publishing and a
Director of its parent company, Reed-Elsevier plc. During Mr. Krakoff's 23-year
tenure, Reed-Elsevier's exhibition business became one of the largest worldwide
exhibition management companies. Prior to joining Advanstar, Mr. Alic served as
Vice President and Controller of IBM Corporation, and prior thereto was the
Chairman of Reed Exhibition Companies. Prior to joining the Company, Mr. Siegel
was President and Chief Executive Officer of LEXIS-NEXIS, a unit of Reed
Elsevier, Inc. and prior thereto was President and Chief Executive Officer of
Reed Reference Publishing, another division of Reed Elsevier, Inc. Messrs.
Krakoff and Alic, collectively, have invested $2.0 million in the business.
Messrs. Krakoff and Alic and other members of the Company's management, subject
to vesting, have direct or indirect interests in approximately 15% of Holdings'
common stock (the "Common Stock") on a fully diluted basis.
 
BUSINESS STRATEGY
 
  The Company's business strategy is to grow profitability by solidifying its
position as a leading provider of comprehensive "one-stop" business-to-business
marketing communications solutions. The Company plans to achieve its strategic
objectives by (i) expanding its product and service offerings within each of
its industry sectors to obtain a larger share of its customers' marketing
expenditures, (ii) selectively entering new industry sectors and (iii)
leveraging the strengths of its centralized administrative and production
operations.
 
                                       3
<PAGE>
 
 
  Expand Product Offerings. The Company plans to "fill-in" its product and
service offerings within its existing industry sectors through selective
acquisitions and joint ventures, strategic new product launches and
international expansion.
 
  .  Selective Acquisitions and Joint Ventures. The Company intends to
     continue to engage in strategic acquisitions and joint ventures within
     its existing industry sectors. The Company believes it can improve its
     overall competitive position through such acquisitions by (i) applying
     its extensive industry experience to enhancing the performance of newly
     acquired businesses, (ii) integrating acquisitions and joint ventures
     into its cost-efficient infrastructure, (iii) cross-selling new products
     and services with existing products and services and (iv) using new
     products and services to increase visibility within its markets. Since
     the HFCP III Acquisition and excluding the MAGIC Acquisition, Advanstar
     has completed or expects to complete 19 acquisitions and joint ventures
     for purchase prices aggregating approximately $130.8 million in the
     information technology, telecommunications, beauty, travel,
     entertainment and call center sectors.
 
  .  Strategic New Product Launches. The Company has successfully developed
     new products within its existing industry clusters and will continue to
     make strategic new product introductions. In 1997, the Company launched
     seven magazines and seven expositions and conferences in existing
     industry sectors to fill-in its existing product offerings. For example,
     in 1997 the Company launched WorldPharm, a pharmaceutical industry
     exposition to be held in Philadelphia in 1998, to complement its strong
     position in pharmaceutical publishing.
 
  .  International Expansion. The Company intends to enhance its position in
     international markets by leveraging its widely recognized brands, its
     experience in international operations and its current customers' demand
     for increased global marketing. The Company currently has operations in
     Canada, the United Kingdom, Hong Kong and Brazil and intends to expand
     further internationally through the extension of existing products into
     new geographic markets, joint ventures with local operating partners and
     selective acquisitions. Many of the Company's existing international
     products are regional in nature (Pan European, Pan Asian or Pan Latin
     American), and future expansion is expected to follow this model. For
     example, in mid-1997, building on its existing strength in the U.S. and
     Asian telecommunications markets, Advanstar acquired two magazines and
     13 conferences serving the Brazilian and Latin American
     telecommunications markets and, in early 1998, acquired Telexpo, the
     largest Latin American telecommunications trade show.
 
  Selectively Enter New Industry Sectors. The Company will selectively enter
new industry sectors in which it believes it can become a leading participant
and achieve attractive margins. For example, the MAGIC Acquisition presented
Advanstar with an ideal opportunity to enter the U.S. men's apparel market with
critical mass and to increase revenue and reduce expenses by leveraging
Advanstar's extensive trade show experience.
 
  Leverage Cost-Effective Centralized Administrative and Production
Facilities. The Company believes that its organizational structure (i) provides
continuing opportunities to produce attractive margins through centralized
functional cost management, (ii) provides a platform to easily introduce new
titles or expositions based on existing products and (iii) facilitates
integration and cost reductions with respect to acquired titles and
expositions. The Company has a long established and highly efficient
centralized publishing infrastructure in both the U.S. and Europe. The Company
focuses on continually improving its systems and processes to provide
effective, low cost operations in circulation, fulfillment, production and
print and paper vendor management. Similar cost-efficient infrastructures are
being established in Asia and in Latin America. In 1997, a centrally managed
exhibition operations function was established in both the U.S. and Europe to
provide consistency of business process and cost effective delivery of these
services. Centralized support also exists in finance and accounting,
information technology and communications, human resources and strategic
planning.

INDUSTRY OVERVIEW
 
  Trade Publications. Trade publications provide key new product or educational
information to readers and a periodic medium for advertisers to reach highly
targeted and select business audiences throughout the year. Trade publications
are generally supported by advertising and are often circulated free-of-charge.
The most effective and profitable publications are those with readership that
includes a high proportion of the individuals who influence purchasing
decisions in a market niche, while avoiding the expense and inefficiency of
circulating to individuals who are not clearly within the target group.
According to a recent study, the U.S. trade publication industry is expected to
grow at a compound annual growth rate of 5.9% between 1995 and 2000, increasing
from a total market size of approximately $7.7 billion in 1995 (consisting of
approximately $5.9 billion in advertising and approximately $1.8 billion in
subscriptions) to approximately $10.2 billion in 2000 (consisting of
approximately $8.2 billion in advertising and approximately $2.0 billion in
subscriptions).
 
  Expositions and Trade Shows. Expositions and trade shows allow exhibitors a
cost-effective means to showcase and sell products and services and to develop
business relationships with many potential customers in a short time period,
while providing attendees an opportunity to view a broad range of products as
well as to interact with numerous suppliers at once. A 1996 study noted that
the cost of closing a sale with a trade show prospect is less than 50% of the
cost of closing a sale in the field. The number of U.S. expositions grew from
approximately 3,300 events in 1989 to approximately 4,400 events in 1996, a
33.8% increase. The amount of net square feet of U.S. expositions grew 65.9%
between 1989 and 1996, from approximately 270 million net square feet in 1989
to approximately 448 million net square feet in 1996. Attendance at U.S.
expositions has grown from approximately 60 million attendees in 1989 to
approximately 101 million attendees in 1996.
 
OWNERSHIP
 
  Advanstar was purchased on May 31, 1996 by HFCP III (the "HFCP III
Acquisition"). HFCP III is a private equity investment fund with committed
equity capital of approximately $1.5 billion. HFCP III, with its predecessor
partnerships, is an experienced investor in the media industry, with current or
former investments in companies including Young & Rubicam Inc., Western
Wireless Corporation, Eller Media Company (which has been sold to Clear Channel
Communications, Inc.) and Hoyts Cinemas Limited. To date, HFCP III has invested
$177.0 million of equity in the Company. See "Principal Stockholders."
 
THE ACQUISITIONS AND REFINANCING
 
  On April 30, 1998, in connection with the Offering, Advanstar acquired MAGIC
for cash consideration of $230.2 million, subject to adjustment based on the
shareholders' equity of MAGIC on the closing date of the MAGIC Acquisition.
MAGIC is a wholly-owned subsidiary of Advanstar, serving as the core asset of
the Company's Retail, Hospitality & Fashion cluster. The Company's fashion
industry sector is managed by Joseph Loggia, MAGIC's former chief executive
officer and current president. Mr. Loggia has entered into a two year
employment agreement with Advanstar and has received options to purchase Common
Stock.
 
  In addition, since June 1, 1997 Advanstar has completed or signed definitive
agreements or letters of intent for 12 other acquisitions or joint ventures
(collectively, the "Other Acquisitions") with purchase prices ranging from
approximately $1.4 million to approximately $17.1 million and aggregating
approximately $77.7 million. The MAGIC Acquisition and the Other Acquisitions
are collectively referred to herein as the "Acquisitions." See "The
Acquisitions and Refinancing."
 
  Additionally, in order to provide greater flexibility in pursuing its growth
strategy, on April 30, 1998 the Company amended (the "Credit Facility
Amendment") its existing senior credit facility (the "Original
 
                                       5

Credit Facility" and, as amended, the "Amended Credit Facility") with The Chase
Manhattan Bank, an affiliate of Chase Securities Inc., and a syndicate of
banks, by increasing its borrowing capacity thereunder from $215.0 million
under the Original Credit Facility to $270.0 million under the Amended Credit
Facility. See "Description of Amended Credit Facility." At the same time, HFCP
III also made an additional equity investment (the "HFCP III Equity
Investment") of approximately $70.0 million in the Company.
 
 
                                ----------------
 
  The Company was incorporated in New York on January 23, 1987 under the name

Accrued Interest on the Exchange
 Notes and Original Notes.........  Interest on each Exchange Note will accrue
                                    from the last date on which interest was
                                    paid on the Original Note surrendered in
                                    exchange therefor or, if no interest has
                                    been paid on the Original Note, from the
                                    date of original issuance of such Original

                                    Notes are accepted for exchange will be
                                    deemed to have waived the right to receive
                                    any payment in respect of interest on the

                                    will receive the accrued interest payable
                                    on November 1, 1998 in accordance with the
                                    Indenture. See "The Exchange Offer -- Terms
                                    of the Exchange Offer."
 
Conditions to the Exchange          The Exchange Offer is subject to certain
 Offer............................  customary conditions. The conditions are
                                    limited and relate in general to
                                    proceedings which have been instituted or
                                    laws which have been adopted that might
                                    impair the ability of the Company to
                                    proceed with the Exchange Offer. As of the
                                    date of this Prospectus, none of these
                                    events had occurred, and the Company
                                    believes their occurrence to be unlikely.
                                    If any such conditions exist prior to the
                                    Expiration Date, the Company may (a)

 Holders..........................  are registered in the name of his broker,
                                    dealer, commercial bank, trust company or
                                    other nominee and who wishes to tender in
                                    the Exchange Offer should contact such
                                    registered holder promptly and instruct

                                    behalf. If such beneficial holder wishes to
                                    tender on his own behalf, such beneficial
                                    holder must, prior to completing and

                                    holder's name or obtain a properly
                                    completed bond power from the registered
                                    holder. The transfer of record ownership
                                    may take considerable time. See "The
                                    Exchange Offer--Procedures for Tendering."

    period ended March 31, 1998.
(2) Represent the results of operations for MAGIC for the three month period
    ended March 31, 1998.
(3) Represents the aggregate results of operations for the three month period
    ended March 31, 1998 for the Other Acquisitions. See "The Acquisitions and

    operating results of a probable divestiture, for consideration of
    approximately $4.0 million, of a trade publication.
(4) Represents the elimination of related party discounts that will not recur
    following the MAGIC Acquisition.
(5) Represents the elimination of director fees that will not recur following
    the MAGIC Acquisition.
(6) Represents incremental amortization of goodwill arising from the
    Acquisitions (based on a preliminary allocation of aggregate purchase
    price) and incremental amortization of intangibles resulting from deferred
    financing costs. The incremental goodwill is being amortized on a straight
    line basis over periods ranging from 20-30 years. The deferred financing
    costs are amortized over the lives of the related debt instruments (5.5-10
    years).
(7) Excludes a nonrecurring compensation expense of approximately $6.5 million
    related to the MAGIC Acquisition.
(8) Represents incremental interest expense arising from the Offering

    incremental interest expense on additional borrowings under the Amended
    Credit Facility.

    to the Company's net operating loss carryforwards. The remaining income tax
    provision represents taxes related to certain state taxes and the Company's
    U.K. subsidiary.
(10) "EBITDA" is defined as operating income before depreciation and
     amortization. EBITDA is not a measure of performance defined by GAAP.
     EBITDA should not be considered in isolation or as a substitute for net
     income or the statement of cash flows which have been prepared in
     accordance with GAAP. EBITDA is provided because management understands
     that it is customarily used in evaluating business communications
     companies. The EBITDA measures presented herein may not be comparable to
     similarly titled measures of other companies.
(11) Calculated using pro forma interest expense of $7.8 million.
(12) Reflects the aggregate purchase prices for the Acquisitions and is net of
     a divestiture, for consideration of approximately $4.0 million, of a trade
     publication.
(13) Represents the HFCP III Equity Investment ($70,000), net of the
     elimination of the capital in excess of par value of acquired entities
     ($947), the elimination of historical accumulated earnings of acquired
     entities ($11,399) and the write-off of previously capitalized deferred
     financing costs ($4,521).

(1) Combines the five months ended May 31, 1996 of the Predecessor with the
    seven months ended December 31, 1996 of Advanstar. On May 31, 1996, the
    HFCP III Acquisition was consummated. Accordingly, certain information
    provided herein for the year ended December 31, 1995 and the five months
    ended May 31, 1996 is not comparable to the statement of operations data of
    Advanstar due to the effects of certain purchase accounting adjustments and
    the financing of the HFCP III Acquisition. Operating and other financial
    data for the Predecessor for the five months ended May 31, 1996 have been
    combined for presentation purposes with the operating and other financial
    data of Advanstar for the seven months ended December 31, 1996, without
    giving effect to purchase accounting or the impact of the financing of the
    HFCP III Acquisition and is not in accordance with GAAP.

(2) Includes identifiable intangibles such as advertiser, exhibitor and
    circulation lists, assembled work force and other intangibles as well as
    goodwill. Amortization increased for the seven months ended December 31,
    1996 and the year ended December 31, 1997 as a result of the HFCP III
    Acquisition completed in May 1996. Purchase prices in excess of fair market
    value of tangible and intangible assets acquired is allocated to goodwill.
    Intangibles are being amortized over lives ranging from 5 to 23 years.
(3) "EBITDA" is defined as operating income before depreciation and
    amortization. EBITDA is not a measure of performance defined by GAAP.
    EBITDA should not be considered in isolation or as a substitute for net
    income or the statement of cash flows which have been prepared in
    accordance with GAAP. EBITDA is provided because management understands
    that it is customarily used in evaluating business communications
    companies. The EBITDA measures presented herein may not be comparable to
    similarly titled measures of other companies.
(4) Working capital is comprised of total current assets, excluding cash and
    cash equivalents, less total current liabilities and excluding current
    maturities of long-term debt. Working capital for Advanstar is negative due
    to the impact of deferred revenue from expositions which are billed and
    collected as deposits up to six months in advance of the respective
    exposition. Consequently, expositions carry little or no accounts
    receivable.

                                 RISK FACTORS
 
  Prior to making an investment decision, prospective investors should
carefully consider, together with the other information included in this
Prospectus, the following risk factors. This Prospectus contains forward
looking statements. These statements are subject to a number of risks and
uncertainties, certain of which are beyond the Company's control.
 
SUBSTANTIAL LEVERAGE; ABILITY TO SERVICE DEBT
 
  As of March 31, 1998, after giving effect to the Pro Forma Adjustments, the
Company would have had approximately $360.0 million of outstanding
Indebtedness, which would have represented 70.0% of total capitalization. For
the year ended December 31, 1997, the Company's pro forma annual interest
payments due on such Indebtedness would have been approximately $31.1 million,
and the Company's pro forma ratio of EBITDA to interest expense would have
been 1.8x. In addition, after giving effect to the Pro Forma Adjustments, the
Company would have had $60.0 million available under the Amended Credit
Facility. Although the Company's cash flow from operations has been sufficient
to meet its debt service obligations in the past, there can be no assurance
that the Company's operating results will continue to be sufficient for the
Company to meet its obligations. See "Unaudited Pro Forma Combined Financial
Information," "Capitalization" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources."
 
  The degree to which the Company is leveraged could have important
consequences to the holders of the Notes, including the following: (i) the
Company's ability to obtain additional financing for acquisitions, capital
expenditures, working capital or general corporate purposes may be impaired in
the future; (ii) a substantial portion of the Company's cash flow from
operations must be dedicated to the payment of principal of and interest on
the Notes and the borrowings under the Amended Credit Facility, thereby
reducing the funds available to the Company for its operations and other
purposes; (iii) certain of the Company's borrowings are and will continue to
be at variable rates of interest, which exposes the Company to the risk of
increased interest rates; (iv) the indebtedness outstanding under the Amended
Credit Facility is secured by the capital stock of the Company and its
subsidiaries and will mature prior to the Notes; and (v) the Company may be
substantially more leveraged than certain of its competitors, which may place
it at a relative competitive disadvantage and make it more vulnerable to
changing market conditions and regulations. See "Description of Amended Credit
Facility" and "Description of Notes."
 
  The Company's ability to make scheduled payments or to refinance its
obligations with respect to its indebtedness will depend on its financial and
operating performance, which, in turn, is subject to prevailing economic
conditions and to certain financial, business and other factors beyond its
control. If the Company's cash flow and capital resources are insufficient to
fund its debt service obligations, the Company may be forced to sell assets,
obtain additional equity capital or restructure its debt. There can be no
assurance that the Company's cash flow and capital resources will be
sufficient for payment of its indebtedness in the future. In the absence of
such operating results and resources, the Company could face substantial
liquidity problems and might be required to dispose of material assets or
operations to meet its debt service and other obligations, and there can be no
assurance as to the timing of such sales or the adequacy of the proceeds which
the Company could realize therefrom. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Liquidity and Capital
Resources" and "Description of Amended Credit Facility."
 
RESTRICTIONS IMPOSED BY AMENDED CREDIT FACILITY
 
  The Amended Credit Facility contains a number of covenants that, among other
things, restrict the ability of the Company to incur additional indebtedness,
pay dividends, prepay subordinated
 
                                      20
<PAGE>
 
indebtedness such as the Notes, dispose of certain assets, enter into sale and
leaseback transactions, create liens, make capital expenditures and make
certain investments or acquisitions and otherwise restrict corporate
activities. In addition, under the Amended Credit Facility, the Company is
required to satisfy specified financial covenants, including cash flow to
total debt, interest coverage and consolidated tangible net worth tests. The
ability of the Company to comply with such provisions may be affected by
events beyond the Company's control. The breach of any of these covenants
could result in a default under the Amended Credit Facility. In the event of
any such default, depending on the actions taken by the lenders under the
Amended Credit Facility, the Company could be prohibited from making any
payments on the Notes. In addition, such lenders could elect to declare all
amounts borrowed under the Amended Credit Facility, together with accrued
interest, to be due and payable. The Amended Credit Facility is secured by,
among other things, the capital stock of the Company and its subsidiaries, and
if the Company were unable to repay such borrowings, the Banks could proceed
against their collateral. If the lenders or the holders of any other secured
indebtedness were to foreclose on the collateral securing the Company's
obligations to them, it is possible that there would be insufficient assets
remaining after satisfaction in full of all such indebtedness to satisfy in
full the claims of the holders of the Notes. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources," "Description of Amended Credit Facility" and "Description
of Notes."
 
SUBORDINATION; UNSECURED STATUS OF THE NOTES AND THE GUARANTEES
 
  The payment of principal of and interest on, and any premium or other
amounts owing in respect of, the Notes will be subordinated to the prior
payment in full of all existing and future Senior Indebtedness of the Company,
including all amounts owing under the Amended Credit Facility. As of March 31,
1998, after giving effect to the Pro Forma Adjustments, the aggregate amount
of Senior Indebtedness of the Company would have been approximately $210.0
million (excluding unused commitments), all of which would have been secured.
Consequently, in the event of a bankruptcy, liquidation, dissolution,
reorganization or similar proceedings with respect to the Company, assets of
the Company will be available to pay obligations on the Notes only after
Senior Indebtedness has been paid in full, and there can be no assurance that
there will be sufficient assets to pay amounts due on all or any of the Notes.
 
  The Notes will be unsecured and will be subordinated in right of payment to
all existing and future Senior Indebtedness of the Company. The Notes will
rank pari passu with any future Senior Subordinated Indebtedness of the
Company and will rank senior to all Subordinated Obligations of the Company.
The Note Guarantees will be unsecured, senior subordinated obligations of the
Guarantors, subordinated in right of payment to all existing and future Senior
Indebtedness of the Guarantors, including the guarantees of Indebtedness under
the Amended Credit Facility. As of March 31, 1998, after giving effect to the
Pro Forma Adjustments: (i) the outstanding Senior Indebtedness of the Company
would have been $210.0 million (exclusive of unused commitments), all of which
would have been secured; (ii) the Company would have had no Senior
Subordinated Indebtedness outstanding other than the Notes and no Subordinated
Obligations; (iii) the outstanding Senior Indebtedness of the Guarantors,
consisting entirely of guarantees of the Amended Credit Facility, would have
been $210.0 million, all of which would have been secured; and (iv) the
Guarantors would have had no outstanding Senior Subordinated Indebtedness
other than the Guarantees and no outstanding Subordinated Obligations. See
"Description of Notes--Ranking" and "--Guarantees."
 
  The Indenture permits the Company and the Subsidiary Guarantors to incur
certain secured indebtedness, including indebtedness under the Amended Credit
Facility, which will be secured by a lien on substantially all of the assets
of the Company and the Guarantors. The Notes and the Guarantees are unsecured
and therefore do not have the benefit of such collateral. Accordingly, if an
event of default occurs under the Amended Credit Facility, the lenders
thereunder may foreclose upon such collateral to the exclusion of the holders
of the Notes, notwithstanding the existence of an event
 
                                      21
<PAGE>
 
of default with respect to the Notes. In such event, such assets would first
be used to repay in full amounts outstanding under the Amended Credit
Facility, resulting in all or a portion of the Company's assets being
unavailable to satisfy the claims of the holders of Notes and other unsecured
Indebtedness.
 
FRAUDULENT TRANSFER CONSIDERATIONS
 
  The incurrence of indebtedness (such as the Notes) is subject to review
under relevant federal and state fraudulent conveyance and similar statutes in
a bankruptcy or reorganization case or a lawsuit by or on behalf of creditors
of the Company. Under these statutes, if a court were to find that obligations
(such as the Notes) were incurred with the intent of hindering, delaying or
defrauding present or future creditors, that the Company received less than a
reasonably equivalent value or fair consideration for those obligations and,
at the time of the incurrence of the obligations the obligor either (i) was
insolvent or rendered insolvent by reason thereof, (ii) was engaged or was
about to engage in a business or transaction for which its remaining
unencumbered assets constituted unreasonably small capital or (iii) intended
to or believed that it would incur debts beyond its ability to pay such debts
as they matured or became due, such court could void or subordinate the
obligations in question.
 
  The measure of insolvency for purposes of a fraudulent conveyance claim will
vary depending upon the law of the jurisdiction being applied. Generally,
however, a company will be considered insolvent a particular time if the sum
of its debts at that time is greater than the then fair saleable value of its
assets or if the fair saleable value of its assets at that time is less than
the amount that would be required to pay its probable liability on its
existing debts as they become absolute and mature. The Company believes that
it is (i) not insolvent, (ii) in possession of sufficient capital to run its
business effectively and (iii) incurring debts within its ability to pay as
the same mature or become due.
 
  In addition, the Subsidiary Guarantees may be subject to review under
relevant federal and state fraudulent conveyance and similar statutes in a
bankruptcy or reorganization case or a lawsuit by or on behalf of creditors of
any of the Subsidiary Guarantors. In such a case, the analysis set forth above
would generally apply, except that the Subsidiary Guarantees could also be
subject to the claim that, since the Subsidiary Guarantees were incurred for
the benefit of the Company (and only indirectly for the benefit of the
Subsidiary Guarantors), the obligations of the Subsidiary Guarantors
thereunder were incurred for less than reasonably equivalent value of fair
consideration. A court could void any of the Subsidiary Guarantors'
obligations under the Subsidiary Guarantees, subordinate the Subsidiary
Guarantees to other indebtedness of a Subsidiary Guarantor or take other
action detrimental to the holders of the Notes.
 
POSSIBLE UNENFORCEABILITY OF SUBSIDIARY GUARANTEES
 
  The Company derives certain of its operating income from its subsidiaries.
The holders of the Notes will have no direct claim against such subsidiaries
other than a claim created by one or more of the Note Guarantees, which may
themselves be subject to legal challenge in a bankruptcy or reorganization
case or a lawsuit by or on behalf of creditors of a Subsidiary Guarantor. See
"--Fraudulent Transfer Considerations." If such a challenge were upheld, such
Note Guarantees would be invalid and unenforceable. To the extent that any of
such Note Guarantees are not enforceable, the rights of the holders of the
Notes to participate in any distribution of assets of any Subsidiary Guarantor
upon liquidation, bankruptcy, reorganization or otherwise will, as is the case
with other unsecured creditors of the Company, be subject to prior claims of
creditors of that Subsidiary Guarantor. The Company must rely in part upon
distributions from its subsidiaries to generate the funds necessary to meet
its obligations, including the payment of principal of and interest on the
Notes. The Indenture contains covenants that restrict the ability of the
Company's subsidiaries to enter into any agreement limiting distributions and
transfers, including dividends. However, the ability of the
 
                                      22
<PAGE>
 
Company's subsidiaries to make distributions may be restricted by among other
things, applicable state corporate laws and other laws and regulations or by
terms of agreements to which they are or may become a party. In addition,
there can be no assurance that such distributions will be adequate to fund the
interest and principal payments on the Amended Credit Facility and the Notes
when due. See "Description of Notes."
 
CHANGE OF CONTROL
 
  Upon a Change of Control, holders of the Notes will have the right to
require the Company to repurchase all or any part of such holders' Notes at a
price equal to 101% of the principal amount thereof, plus accrued and unpaid
interest, if any, to the date of repurchase. The events that constitute a
Change of Control under the Notes will also constitute a default under the
Amended Credit Facility, which will prohibit the purchase of the Notes by the
Company in the event of certain Change of Control events unless and until such
time as the Company's indebtedness under the Amended Credit Facility is repaid
in full. There can be no assurance that the Company would have sufficient
financial resources available to satisfy all of its obligations under the
Amended Credit Facility and the Notes in the event of a Change of Control. The
Company's failure to purchase the Notes would result in a default under the
Indenture and under the Amended Credit Facility, which could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Description of Amended Credit Facility" and "Description of
Notes--Change of Control."
 
DEPENDENCE ON DEMAND FOR ADVERTISING
 
  After giving effect to the Pro Forma Adjustments, 46.4% of the Company's
total revenue in 1997 would have been derived from advertising sales. Should a
general economic downturn or a recession in the United States occur in the
future, the Company's advertisers may reduce their advertising budgets. Any
material decline in the demand for advertising could have an adverse effect on
the Company's business, financial condition and results of operations.
 
DEPENDENCE ON VENUES AND DATES FOR EXPOSITIONS AND CONFERENCES
 
  The success of an exposition or a conference depends in part upon its date
and location. The market for desirable dates and locations is highly
competitive. The Company generally maintains multi-year reservations for its
exposition and conference venues and dates. However, consistent with industry
practice, the Company does not pay for these reservations and the reservations
are not binding on the facility owners until a contract is signed. Contracts
typically guarantee the right to certain venues or dates for only one year and
there can be no assurance that the Company's reservations will lead to signed,
binding contracts with facility owners. In the event that the Company loses
its rights to exposition/conference dates or locations, the profitability and
future prospects of the expositions or conferences affected, and the Company's
overall business, financial condition and results of operations could be
materially and adversely affected. No assurance can be given that the Company
can maintain the date or location of any of its expositions or conferences. In
addition, the fact that exhibitions and conferences are held on pre-scheduled
dates at specific locations could make them vulnerable to events outside of
the Company's control, such as natural catastrophes, labor strikes or
transportation shutdowns.
 
IMPORTANCE OF MAGIC
 
  Historically, none of the Company's trade shows has individually represented
a significant portion of the Company's exposition revenue. The MAGIC trade
shows, however, would have represented an aggregate of 29.7% of the Company's
pro forma exposition revenue for the year ended December 31, 1997 and 22.1%
and 13.1% of the Company's pro forma EBITDA and pro forma net revenue,
respectively, for the same period. The Company expects that the MAGIC trade
shows will continue to
 
                                      23
<PAGE>
 
represent a significant portion of the Company's overall revenue in the
future. Although the Company believes it has a diversified portfolio of
expositions, a significant decline in the performance of one or both of the
February or August MAGIC trade shows could have a material adverse effect on
the Company's business, financial condition and results of operations.
 
EFFECT OF INCREASE IN PAPER AND POSTAGE COSTS
 
  The price of paper is a significant expense of the Company relating to its
print products and direct mail solicitations. Although the Company has
implemented measures designed to substantially offset historical price
increases, such increases, despite such offsetting measures, could have a
material adverse effect on the Company's business, financial condition and
results of operations. Postage for product distribution and direct mail
solicitation is also a significant expense of the Company. The Company
generally uses the United States Postal Service. Postage costs increase
periodically and can be expected to increase in the future. No assurance can
be given that the Company can pass such cost increases through to its
customers.
 
EXPANSION RISKS AND IMPACT ON FUTURE OPERATING RESULTS
 
  The Company's objective is to grow through, among other things, strategic
acquisitions. The Company's acquisition strategy entails risks inherent in
assessing the value, strengths, weaknesses, contingent and other liabilities
and potential profitability of acquisition candidates and in integrating the
operations of acquired businesses. There can be no assurance that acquisition
opportunities will be available, that the Company will have access to the
capital required to finance potential acquisitions or that any business
acquired will be integrated successfully or prove profitable. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations." Additionally, the integration of acquisitions, in particular the
MAGIC Acquisition, requires and will require substantial attention from
management. The diversion of the attention of management, and any difficulties
encountered in the transition process, could have a material adverse impact on
the Company's revenue and operating results. In addition, the process of
integrating the various businesses could cause the interruption of, or a loss
of momentum in, the activities of some or all of these businesses, which could
have a material adverse effect on the Company's business, financial condition
or results of operations. There can be no assurance that the Company will
realize any of the anticipated benefits from the MAGIC Acquisition or any of
the other acquisitions it consummates.
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company has benefited substantially from the leadership and experience
of its senior management team, and is dependent on their continued services in
order to successfully implement its business strategy. Although the Company
has entered into employment agreements with Robert Krakoff and James Alic,
there can be no assurance that these and other key personnel will continue to
be employed by the Company or that the Company will be able to attract and
retain qualified personnel in the future. Although the Company believes that
it could replace key employees in an orderly fashion should the need arise,
the loss of such key personnel could have a material adverse affect on the
Company's business, financial condition or results of operations. The Company
does not currently maintain key-man life insurance policies on its executive
officers. See "Management."
 
COMPETITION
 
  Competition for the Company's products and services is highly fragmented,
both by product and geography, and exists at many levels. On a global level,
there are several much larger international firms--such as Reed Elsevier and
United News and Media--which operate in many geographic markets and have broad
product offerings in publishing, expositions and conferences and marketing
services. Many of these competitors are better capitalized and have
substantially greater financial and other resources than the Company. In a few
cases, these firms operate in the same market as the Company.
 
                                      24
<PAGE>
 
In general, these large firms are organized and market their products and
services by product and geographic location, not on an integrated basis.
Within each particular industry sector, the Company generally has a large
number of direct and indirect competitors. In some cases, these competitors
operate in several geographic areas. In other cases, they operate in only one
geographic market. In most cases, these competitors are small to medium-sized
corporations. However, in several industries markets such as information
technology and healthcare, there are large competitors focused on a single
industry. In expositions and conferences in particular, there are many not-
for-profit association competitors and, in several countries, the exposition
hall owner and operator may also be a competitor. In any given publishing
marketplace in a particular country, there are typically two to five direct
competitors for both readers and advertisers. Additionally, there are usually
many indirect competitors who define market segments differently and thus may
be alternatives for either the reader or the advertiser. Exposition and
conference competition in each market and country occurs on many levels. There
is seldom any truly direct competitor for a particular event, given the
uniqueness of venue and date. However, given the availability of alternative
venues and the ability to define events for particular market segments and/or
with different strategic positioning, the range of competition for exposition
dollars, sponsorships and show attendees and conferees is extensive. Because
there are few barriers to entry, the Company anticipates that, as the trade
publications and expositions industries evolve, additional competitors with
greater resources than the Company may enter the markets, or particular
segments of the markets, thereby intensifying competition. See "Business--
Competition."
 
RISKS ASSOCIATED WITH INTERNATIONAL EXPANSION
 
  The Company's growth strategy includes international expansion. There are
certain risks inherent in doing business in international markets, such as the
uncertainty of product acceptance by different cultures, the risks of
divergent business expectations or cultural incompatibility in establishing
joint ventures with foreign partners, difficulties in staffing and managing
multinational operations, currency fluctuations, changing economic conditions,
state-imposed restrictions on the repatriation of funds and potentially
adverse tax consequences. There can be no assurance that one or more of such
factors will not have a material adverse effect on the Company's future
international operations and, consequently, on the Company's business,
financial condition and results of operations.
 
ABSENCE OF PUBLIC MARKET
 
  Prior to the Offering, there was no public market for the Notes and there
can be no assurance that such a market for the Notes or the Exchange Notes
will develop or, if such a market develops, as to the liquidity of such
market. The Company does not intend to apply for listing of the Notes or the
Exchange Notes on any securities exchange; however, the Notes are eligible for
trading in the PORTAL market. If the Notes or the Exchange Notes are traded
after their initial issuance, they may trade at a discount from their initial
offering price, depending upon prevailing interest rates, the market for
similar securities, the performance of the Company and certain other factors.
The Company has been advised by the Initial Purchasers that they intend to
make a market in the Notes and the Exchange Notes as permitted by applicable
laws and regulations; however, the Initial Purchasers are not obligated to do
so and any such market making activities may be discontinued at any time
without notice. In addition, such market making activities may be limited
during the Exchange Offer. Until the Company performs its obligations under
the Registration Rights Agreement, the Notes may only be offered or sold
pursuant to an exemption from the registration requirements of the Securities
Act and applicable state securities laws or pursuant to an effective
registration statement under the Securities Act and applicable state
securities laws. See "Transfer Restrictions," "Exchange and Registration
Rights Agreement" and "Plan of Distribution."

CONTROL BY HFCP III
 
  HFCP III owns, directly or indirectly, substantially all of the outstanding
capital stock of Holdings, the parent company of the Company, and can
effectively control the affairs and policies of the Company. There can be no
assurance that the interests of HFCP III will not conflict with the interests
of the holders of the Notes. See "Principal Stockholders."
 
PROCEDURES FOR TENDER OF ORIGINAL NOTES
 
  The Exchange Notes will be issued in exchange for Original Notes only after
timely receipt by the Exchange Agent of such Original Notes, a properly
completed and duly executed Letter of Transmittal and all other required
documents. Therefore, holders of Original Notes desiring to tender such
Original Notes in exchange for Exchange Notes should allow sufficient time to
ensure timely delivery. Neither the Exchange Agent nor the Company is under
any duty to give notification of defects or irregularities with respect to
tenders of Original Notes for exchange. Any holder of Original Notes who
tenders in the Exchange Offer for the purpose of participating in a
distribution of the Exchange Notes will be required to comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. Each broker-dealer that receives
Exchange Notes for its own account in exchange for Notes, where such Original
Notes were acquired by such broker-dealer as a result of market-making
activities or any other trading activities, must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Notes. See
"Plan of Distribution."
 
CONSEQUENCES OF FAILURE TO EXCHANGE ORIGINAL NOTES
 
  The Original Notes have not been registered under the Securities Act and are
subject to substantial restrictions on transfer. Original Notes that are not
tendered in exchange for Exchange Notes or are tendered but not accepted will,
following consummation of the Exchange Offer, continue to be subject to the
existing restrictions upon transfer thereof. The Company does not currently
anticipate that it will register the Original Notes under the Securities Act.
To the extent that Original Notes are tendered and accepted in the Exchange
Offer, the trading market for untendered and tendered but unaccepted Original
Notes could be adversely affected. See "The Exchange Offer -- Consequences of
Failure to Exchange."

                       THE ACQUISITIONS AND REFINANCING
 
  The MAGIC Acquisition. On April 30, 1998, Advanstar acquired MAGIC for cash
consideration of $230.2 million, subject to adjustment based on the
shareholders' equity of MAGIC on the closing date of the MAGIC Acquisition,
and MAGIC became a wholly-owned subsidiary of Advanstar, serving as the core
asset of the Company's Retail, Hospitality & Fashion cluster. The Company's
fashion industry sector is managed by Joseph Loggia, MAGIC's former chief
executive officer and current president. Mr. Loggia has entered into a two
year employment agreement with Advanstar and has received options to purchase
Common Stock.
 
  The Other Acquisitions. In addition, since June 1, 1997 Advanstar has
completed or signed definitive agreements or letters of intent for 12 other
acquisitions or joint ventures (collectively, the "Other Acquisitions") with
purchase prices ranging from approximately $1.4 million to approximately $17.1
million and aggregating approximately $77.7 million. The Other Acquisitions
include: (i) the acquisition in June 1997 of Telepress, a Brazilian trade
publication and conference business focused on the Latin American
telecommunications market; (ii) the buyout in November 1997 of a minority
partner, CCI, in Hong Kong, thus creating a wholly-owned publishing platform
in Asia; (iii) the acquisition in February 1998 of Telexpo, a Brazilian
telecommunications exposition; (iv) the joint venture in February 1998 with
the Video Software Dealers Association (the "VSDA") whereby Advanstar became a
50% owner of the VSDA annual convention and trade show, the world's largest
trade event for the home video industry, and the VSDA became a 50% partner in
the Company's East Coast Video Show; (v) the joint venture in February 1998
with Wideband, Inc., a leading publisher in the consumer electronics market
that recently launched Li(C)ense!, a magazine targeting the same industry as
the Company's leading licensing exposition and conference; (vi) the
acquisition in March 1998 of TelEvolution, a call center exposition and
conference in Canada; (vii) the acquisition in March 1998 of Teleprofessional,
a U.S. trade publisher in the call center market; (viii) the acquisition in
May 1998 of SCANTECH, the leading U.S. exposition in the automatic data
capture market; (ix) the acquisition in May 1998 of Applied Business
teleCommunications, producer of the leading expositions and conferences for
the video conferencing and long distance learning industries; (x) the
acquisition in May 1998 of Post, a magazine servicing the post production
activities of the film and television industries; (xi) the execution of a
definitive agreement (scheduled to close in June 1998) to purchase full
ownership rights in, and execution of a long-term sponsorship agreement with
LIMA (the Licensing International Merchandisers Association) for, the
licensing exposition and conference; and (xii) the execution of a letter of
intent for the acquisition (expected June/July 1998) of a U.K. company that
owns a publication that will become part of the Company's Retail, Hospitality
& Fashion cluster.
 
  The Refinancing. Additionally, in order to provide greater flexibility in
pursuing its growth strategy, the Company entered into the Credit Facility
Amendment on April 30, 1998, thereby increasing its borrowing capacity from
$215.0 million under the Original Credit Facility to $270.0 million under the
Amended Credit Facility. See "Description of Amended Credit Facility." HFCP
III also made the HFCP III Equity Investment of approximately $70.0 million on
April 30, 1998.

                                USE OF PROCEEDS
 
  The Company will not receive any proceeds from the Exchange Offer. The
Company has agreed to bear the expenses of the Exchange Offer pursuant to the
Registration Rights Agreement. No underwriter is being used in connection with
the Exchange Offer.

                         UNAUDITED PRO FORMA COMBINED
                             FINANCIAL INFORMATION
 
  The unaudited pro forma combined balance sheet as of March 31, 1998 includes
the historical accounts of Advanstar and gives effect to the Acquisitions and
Refinancing and the divestiture of a trade publication as if they had occurred
as of March 31, 1998. The unaudited pro forma combined statements of
operations for the fiscal year ended December 31, 1997 and the three month
period ended March 31, 1998 include the historical operations of Advanstar and
gives effect to the Acquisitions and Refinancing and the divestiture of a
trade publication as if they had occurred on January 1, 1997 and January 1,
1998, respectively. The pro forma adjustments relating to the Acquisitions and
Refinancing together with the elimination of operating results of a
divestiture, for consideration of approximately $4.0 million, of a trade
publication constitute the "Pro Forma Adjustments."
 
  The unaudited pro forma combined financial information, which has been
prepared by the Company's management, has been derived from the historical
statements of operations and balance sheets of Advanstar, MAGIC and the Other
Acquisitions. The Acquisitions will be accounted for under the purchase method
of accounting using the assumptions and adjustments disclosed in the notes to
the unaudited pro forma combined financial information. A preliminary
allocation of the aggregate purchase price has been made based on available
information.
 
  The unaudited pro forma combined financial information is not designed to
represent and does not represent what the Company's results of operations
actually would have been had the aforementioned transactions been completed as
of the dates indicated, or to project the Company's results of operations for
any future period. Results of operations for the three month period ended
March 31, 1998 are not necessarily indicative of the results that can be
expected for future periods or the entire year, principally due to the timing
of certain exposition events. The Pro Forma Adjustments are based on available
historical financial information and should be read in conjunction with
"Capitalization," "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the financial statements and notes thereto and
other financial information appearing elsewhere herein.

(1)  Represents the results of operations for Advanstar for the year ended
     December 31, 1997 and the three month period ended March 31, 1998, as
     applicable.
(2)  Represent the results of operations for MAGIC for the twelve month period
     ended December 31, 1997 and the three month period ended March 31, 1998,
     as applicable.
(3)  Represents the aggregate results of operations for the twelve month
     periods ended December 31, 1997 and the three month periods ended March
     31, 1998, as applicable, for the Other Acquisitions. See "The Acquisitions
     and Refinancing--Other Acquisitions." Also includes the elimination of
     operating results of a divestiture, for consideration of approximately
     $4.0 million, of a trade publication.
(4)  Represents the elimination of related party discounts that will not recur
     following the MAGIC Acquisition.
(5)  Represents the elimination of director fees that will not recur following
     the MAGIC Acquisition.
(6)  Represents incremental amortization of goodwill arising from the
     Acquisitions (based on preliminary allocations of aggregate purchase
     price) and incremental amortization of intangibles resulting from deferred
     financing costs. The incremental goodwill is being amortized on a straight
     line basis over periods ranging from 20-30 years. The deferred financing
     costs are amortized over the lives of the related debt instruments (5.5-10
     years).
(7)  Represents incremental interest expense arising from the Offering
     (including amortization of original issue discount on the Notes) and
     incremental interest expense on additional borrowings under the Amended
     Credit Facility. Adjustments to interest expense have been calculated as
     follows:

</TABLE>
 
 For the purpose of calculating pro forma interest expense, the Company
 used LIBOR as of December 31, 1997.
(8)  A tax provision has not been reflected for income before income taxes due
     to the Company's net operating loss carryforwards. The remaining income
     tax provision represents taxes related to certain state taxes and the
     Company's U.K. subsidiary.
(9)  "EBITDA" is defined as operating income before depreciation and
     amortization. EBITDA is not a measure of performance defined by GAAP.
     EBITDA should not be considered in isolation or as a substitute for net
     income or the statement of cash flows which have been prepared in
     accordance with GAAP. EBITDA is provided because management understands
     that it is customarily used in evaluating business communications
     companies. The EBITDA measures presented herein may not be comparable to
     similarly titled measures of other companies.
(10) Excludes a nonrecurring compensation expense of $6.5 million related to
     the MAGIC Acquisition.
(11) Calculated using pro forma interest expense of $31.1 million for the
     twelve month period ended December 31, 1997 and $7.8 million for the
     three month period ended March 31, 1998.

(1) Combines the five months ended May 31, 1996 of the Predecessor with the
    seven months ended December 31, 1996 of Advanstar. On May 31, 1996, the
    HFCP III Acquisition was consummated. Accordingly, certain information
    provided herein for the year ended December 31, 1995 and the five months
    ended May 31, 1996 is not comparable to the statement of operations data
    of Advanstar due to the effects of certain purchase accounting adjustments
    and the financing of the HFCP III Acquisition. Operating and other
    financial data for the Predecessor for the five months ended May 31, 1996
    have been combined for presentation purposes with the operating and other
    financial data of Advanstar for the seven months ended December 31, 1996,
    without giving effect to purchase accounting or the impact of the
    financing of the HFCP III Acquisition and is not in accordance with GAAP.
(2) Amortized assets include identifiable intangibles such as advertiser,
    exhibitor and circulation lists, assembled work force and other
    intangibles as well as goodwill. Amortization for 1993 and 1994 reflects
    the amortization of reorganization value in excess of identifiable assets
    as required as a result of the Predecessor's emergence on January 23, 1992
    from its prepackaged Chapter 11 filing. The Predecessor recorded $94.4
    million of reorganization value in excess of identifiable tangible and
    intangible assets and amortized it over three years.
(3) Includes identifiable intangibles such as advertiser, exhibitor and
    circulation lists, assembled work force and other intangibles as well as
    goodwill. Amortization increased for the seven months ended December 31,
    1996 and the year ended December 31, 1997 as a result of the HFCP III
    Acquisition completed in May 1996. Purchase prices in excess of fair
    market value of tangible and intangible assets acquired is allocated to
    goodwill. Intangibles are being amortized over lives ranging from 5 to 23
    years.
(4) "EBITDA" is defined as operating income before depreciation and
    amortization. EBITDA is not a measure of performance defined by GAAP.
    EBITDA should not be considered in isolation or as a substitute for net
    income or the statement of cash flows which have been prepared in
    accordance with GAAP. EBITDA is provided because management understands
    that it is customarily used in evaluating business communications
    companies. The EBITDA measures presented herein may not be comparable to
    similarly titled measures of other companies.
(5) Working capital is comprised of total current assets, excluding cash and
    cash equivalents, less total current liabilities and excludes current
    maturities of long-term debt. Working capital for Advanstar is negative
    due to the impact of deferred revenue from expositions which are billed
    and collected as deposits up to six months in advance of the respective
    exposition. Consequently, expositions carry little or no accounts
    receivable.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW--ADVANSTAR
 
  Advanstar is a leading provider of global, multi-product marketing
communications services, principally through controlled circulation trade,
business and professional magazines and trade shows, expositions and
conferences. Advanstar also provides a broad range of other marketing services
products, including direct mail and database products and services.
 
  On May 31, 1996, the HFCP III Acquisition was consummated. See Note 1 to
Advanstar's Consolidated Financial Statements.
 
  During 1996 and 1997, Advanstar embarked on a strategic acquisition program
designed to fill in existing markets served by Advanstar's industry clusters
or to establish dominant positions in new markets with attractive operating
and growth characteristics. Advanstar completed nine acquisitions during 1996
and 1997 for aggregate purchase prices of approximately $58 million. Advanstar
has continued this program in early 1998, completing, in addition to the MAGIC
Acquisition, an additional eight acquisitions or joint ventures for aggregate
purchase prices of approximately $62.2 million.
 
  Advanstar recognizes revenue from its publishing activities throughout the
year based on the issue dates of its publications. With respect to expositions
and trade shows, revenue and related direct event expenses are recognized in
the month a show or conference is held. Consequently, during the year,
Advanstar will reflect on its balance sheet the deferred revenue collected and
prepaid expenses incurred for a given event's next scheduled show. A portion
of booth revenues are collected up to a year in advance for Advanstar's
expositions. These balance sheet deferrals are recognized and released to the
income statement in the month the event is held.
 
  Advanstar's principal sources of revenue are derived from advertising and
subscriptions in its publications, booth rentals, attendee revenue, and
seminar and conference registrations from its expositions and trade shows, and
sales of its marketing services products. For the year ended December 31, 1997
Advanstar derived 59.8% of its revenue from publishing, 32.8% from expositions
and conferences and 7.4% from marketing services products. During 1997,
Advanstar realigned its internal operational structure into four industry or
market focused clusters. These four clusters, Retail, Hospitality & Fashion;
Healthcare & Pharmaceutical; Information Technology & Communications; and
Manufacturing & Processing, each contain all of Advanstar's products and
services directed toward its respective industry or market. For 1997, the
Retail, Hospitality & Fashion cluster represented 31.2% of Advanstar's total
revenue; Healthcare & Pharmaceuticals represented 20.6%; Information
Technology & Communications represented 22.8%; and Manufacturing & Processing
represented 17.3%. Additionally, Advanstar established a Market Development
cluster, accounting for 7.9% of total revenue in 1997, to focus on developing
properties in markets where Advanstar looks to expand its selection of
products and services. See "Business--Products and Services--Market
Development."
 
  The 1996 combined financial data were accumulated from the historical
financial statements of the Predecessor for the period from January 1, 1996 to
May 31, 1996 and of Advanstar for the period from June 1, 1996 to December 31,
1996. See "Selected Historical Consolidated Financial and Other Data of
Advanstar and the Predecessor." The combined financial data is presented for
comparative purposes only and does not purport to reflect the operating
results of Advanstar if Advanstar had been controlled by HFCP III for the full
year.

FIRST QUARTER 1998 COMPARED TO FIRST QUARTER 1997
 
  Net revenue. Net revenue for the first quarter of 1998 increased $6.0
million, or 12.1%, to $55.7 million in 1998 from $49.7 million for the first
quarter of 1997. Revenue growth for the quarter was due primarily to growth in
the base business, which increased $6.9 million, or 15.5%, from $44.4 million
in 1997 to $51.3 million in 1998. Base revenue growth was due significantly to
aggregate improved performance in the Retail, Hospitality & Fashion cluster,
the Manufacturing & Processing cluster and the Information Technology &
Communications cluster, partially offset by decreased revenue from certain
properties in the Healthcare & Pharmaceutical cluster. Of the overall growth
in the base business, $1.8 million was attributable to timing differences in
certain exposition events between the first quarters of 1997 and 1998.
Exposition events are often held over different dates from one year to the
next which will occasionally result in reported exposition results moving from
one quarter to another between years. Revenue for the quarter from properties
acquired since the HFCP III Acquisition was $4.4 million, a decrease of $0.9
million from the first quarter of 1997. Of the decrease, $2.8 million was due
to the timing of certain exposition events which were held in the first
quarter of 1997 but not until the second quarter of 1998.
 
  Production, selling and other direct expenses. Production, selling and other
direct expenses for the first quarter of 1998 increased $4.1 million, or
12.5%, to $36.9 million from $32.8 million for the first quarter of 1997.
Selling and promotion expenses increased $1.4 million in the first quarter of
1998, or 13.6%, due to investments made in properties in the Healthcare &
Pharmaceutical cluster, for sales resources across the new market focused
cluster groups, and for exposition promotion in support of newly acquired
events and growth in established shows. Exposition facility costs increased
$0.7 million in the first quarter of 1998, or 14.8%, due primarily to growth
in the size of several events and expansion into new venues for certain shows.
Publication production costs for printing, paper and postage increased $0.5
million in the first quarter of 1998, or 8.8%, due to growth in ad pages and
increases in postage rates and paper costs over the first quarter of 1997. All
other direct expenses
 
                                      38
<PAGE>
 
increased $1.5 million in the first quarter of 1998 for editorial,
circulation, exposition show management and department support costs.
 
  General and administrative expenses. General and administrative expenses for
the first quarter of 1998 increased $0.8 million, or 10.3%, to $8.6 million
from $7.8 million for the first quarter of 1997. The increase was largely
caused by incremental expenses relating to the operations of acquired
businesses and expansion of infrastructure to support the new market focused
organization and expected future growth.
 
  Operating income. For the first quarter of 1998, operating income increased
$1.0 million, or 27.8%, to $4.6 million from $3.6 million for the first
quarter of 1997. The increase was due to improved operating performance.
 
  Interest expense. Interest expense for the first quarter of 1998 increased
$0.1 million, or 2.7%, to $3.8 million from $3.7 million for the first quarter
of 1997, due to the incurrence of additional indebtedness necessary to fund
acquisitions completed in 1997 and the first quarter of 1998.
 
  Net income. Net income for the first quarter of 1998 increased $1.6 million
to $0.7 million, from a loss of $0.9 million for the first quarter of 1997.
The increase was due to improved operating performance and a reduction of
income tax expense.
 
  EBITDA. EBITDA for the first quarter of 1998 increased $1.2 million, or
12.2% to $11.0 million from $9.8 million for the first quarter of 1997. The
increase was due primarily to the increase in operating income. EBITDA is not
a measure of performance defined by GAAP and should not be considered in
isolation or as a substitute for net income or the statement of cash flows
which have been prepared in accordance with GAAP.
 
1997 COMPARED TO COMBINED 1996
 
  Net revenue. Total net revenue for 1997 increased $36.7 million, or 24.3%,
to $187.7 million from $151.0 million in 1996. Net revenue growth from the
base business contributed $6.9 million, or 19.0%, of the increase and
acquisitions contributed $29.8 million, or 81.0%, of new net revenue. The
increase in base business revenue was primarily due to a $5.6 million increase
in publishing revenue due to improved operating performance of TELECOM ASIA
and other telecommunications and information technology publications, a $3.2
million increase in exposition revenue due to growth in U.S. and European call
center events and an increase in direct mail and database marketing product
revenue, partially offset by a $3.1 million decline in revenue resulting from
the absence of three plastic exhibition events in 1997 in the Manufacturing &
Processing cluster and a $0.2 million decline in revenue resulting from the
discontinuance of a small publication in 1996. These events are held on a two
years on and one year off cycle tied to industry event schedules.
 
  Production, selling and other direct expenses. Production, selling and other
direct expenses for 1997 increased $28.8 million, or 29.6%, to $126.1 million
from $97.3 million in 1996, primarily as a result of increased expenses
relating to the operations of businesses acquired during late 1996 and 1997.
Base business, production, selling and other direct expenses for 1997
increased approximately 9% over the prior year due to increased investment in
circulation, sales staffing and promotion and marketing.
 
  General and administrative expenses. General and administrative expenses for
1997 increased $1.8 million, or 6.2% to $30.7 million from $28.9 million in
1996. $0.7 million of such increase was incremental general and administrative
expenses relating to the operations of acquired businesses and related
expansion of infrastructure, primarily in Brazil and Hong Kong.
 
  Operating income. For 1997, operating income decreased $3.6 million, or
35.3%, from 1996, primarily due to the $6.8 million increase in non-cash
amortization resulting from the HFCP III
 
                                      39
<PAGE>
 
Acquisition. Operating income before amortization increased $6.0 million, or
24.2%, to $30.8 million in 1997 from $24.8 million in 1996. See Note 1 to
Advanstar's Consolidated Financial Statements.
 
  Interest expense. Interest expense for 1997 increased $0.6 million, or 4.1%,
to $15.1 million from $14.5 million in 1996, due to the incurrence of
additional indebtedness necessary to partially fund acquisitions completed in
late 1996 and early 1997. See Notes 1 and 8 to Advanstar's Consolidated
Financial Statements.
 
  Net loss. Net loss for 1997 increased $2.9 million, or 48.3%, to $8.9
million from $6.0 million in 1996, primarily due to increased amortization
resulting from the HFCP III Acquisition, partially offset by improvements in
operating income before amortization.
 
  EBITDA. EBITDA for 1997 increased $5.8 million, or 20.6%, to $34.0 million
from $28.2 million in 1996. This increase was primarily due to a $6.0 million
increase in operating income before amortization, partially offset by a
decrease of $0.2 million in depreciation.
 
COMBINED 1996 COMPARED TO 1995
 
  Net revenue. Total net revenue for 1996 increased $5.7 million, or 3.9%, to
$151.0 million from $145.3 million in 1995. The growth in net revenue was
primarily due to growth in advertising revenue, and was impacted by the
discontinuance of the neurology magazine and the sale of Showbiz Expo in
December 1995. Excluding these dispositions, revenue would have increased
$11.4 million, or 8.1%.
 
  Production, selling and other direct expenses. Production, selling and other
direct expenses increased by $0.4 million, or 0.4%, to $97.3 million in 1996
from $96.9 million in 1995, due to the revenue growth in continuing properties
and management's efforts to increase investment in existing properties,
partially offset by the elimination of expenses associated with the
discontinued neurology magazine and Showbiz Expo.
 
  General and administrative expenses. General and administrative expenses for
1996 increased $1.7 million, or 6.3% to $28.9 million from $27.2 million in
1995, primarily as a result of increased investment in acquisition development
staff and other strategic planning and marketing staff following the HFCP III
Acquisition.
 
  Operating income. Operating income in 1996 decreased $6.3 million, or 38.4%,
to $10.1 million from $16.4 million in 1995, primarily due to the $8.4 million
increase in non-cash amortization resulting from the HFCP III Acquisition.
Operating income before amortization increased $3.6 million, or 17.0%, to
$24.8 million in 1996 from $21.2 million in 1995, due to the publishing
related revenue growth, offset by the discontinuance of the neurology magazine
and Showbiz Expo discussed above. See Note 1 to Advanstar's Consolidated
Financial Statements.
 
  Interest expense, net. Interest expense for 1996 decreased $5.1 million, or
26.0%, to $14.5 million from $19.6 million in 1995, due to the changes in
Advanstar's capital structure and the replacement of the existing credit
facility with an amended credit facility in conjunction with the HFCP III
Acquisition.
 
  Amortization. For 1996, amortization expense increased $10.0 million, or
208.3%, to $14.8 million from $4.8 million in 1995 as a result of the HFCP III
Acquisition, which was accounted for using the purchase method of accounting.
See Note 1 to Advanstar's Consolidated Financial Statements.
 
  Net loss. Net loss for 1996 increased $5.0 million to $6.0 million from $1.0
million in 1995, primarily due to increased amortization resulting from the
HFCP III Acquisition, partially offset by improvements in operating income
before amortization and the decrease in interest expense.
 
 
                                      40
<PAGE>
 
  EBITDA. EBITDA for 1996 increased $3.6 million, or 14.6%, to $28.2 million
from $24.6 million in 1995. This increase was primarily due to a $6.0 million
increase in operating income before amortization, partially offset by a
decrease in other income.
 
LIQUIDITY AND CAPITAL RESOURCES--ADVANSTAR
 
  Cash flows from operating activities. Net cash provided by operations in the
first quarter of 1998 increased $2.7 million to $3.2 million from $0.5 million
in the first quarter of 1997. The increase was due to an increase in net
income of $1.6 million, an increase in depreciation and amortization of $0.1
million due to acquisitions and a $1.0 million decrease in working capital in
the first quarter of 1998 over the first quarter of 1997.
 
  Cash flows from investing activities. Net cash used in investing activities
for the first quarter of 1998 decreased $2.4 million, or 8.7%, to $24.9
million from $27.3 million in the first quarter of 1997. The decrease was
primarily due to a decrease in cash used for acquisitions of $3.0 million.
Additionally, investing activities includes an increase in capital
expenditures of $0.6 million to $1.4 million in the first quarter of 1998 from
$0.8 million in the first quarter of 1997 for additional exposition wall and
lighting systems for use in the Artexpo show group required to meet the growth
in exhibitors.
 
  Cash flows from financing activities. Net cash provided by financing
activities for the first quarter of 1998 decreased $4.8 million, or 17.5%, to
$22.8 million from $27.6 million in the first quarter of 1997, due to lower
levels of net borrowings for the reduced level of acquisitions in the first
quarter of 1998. The Company borrowed $26.5 million under the revolving credit
facility for acquisitions in the first quarter of 1998 and repaid revolving
credit loans of $3.7 million.
 
  Distributions from subsidiaries. There are no significant restrictions on
the ability of the Subsidiary Guarantors to make distributions to the Company.
 
  Capital expenditures. Advanstar's operations are not capital intensive.
Capital expenditures were $2.3 million, $1.1 million, $1.5 million and $1.4
million for 1997, 1996, 1995 and the three months ended March 31, 1998,
respectively. Annual capital expenditures include approximately $1.5 million
for replacement or maintenance level requirements, primarily for expenditures
related to management information systems.
 
OVERVIEW--MAGIC
 
  MAGIC is a leading producer of trade shows for men's, women's and children's
apparel manufacturers, importers and wholesale distributors. MAGIC was
organized in 1933 as a not-for-profit, mutual benefit corporation and held its
first trade show in 1942 with 19 participating manufacturers.
 
  In fiscal 1994, MAGIC became a "for profit" entity and initiated long-term
programs to introduce new events, products and services as well as to improve
customer service. For example, MAGIC introduced WWDMAGIC in February 1995 and
MAGICKids in August 1997. In addition, MAGIC introduced new products including
show directories and guides, on-site advertising and internet services. During
this period, the addition of customer service staff improved customer
responsiveness, while the development of a client sales force supplemented the
customer referral and trade advertising efforts. As a result of these
initiatives, EBITDA for 1997 increased $9.4 million, or 335.7%, to $12.2
million from $2.8 million in fiscal 1994.
 
  Trade shows constitute substantially all of MAGIC's business. Net revenue is
comprised of booth revenue and other show revenue. Booth revenue consists of
trade show booth rentals and other show revenue including on-site advertising,
program sponsorship, hotel and meeting rooms setup and registration fees.
Booth revenue is billed and collected from exhibitors in advance of each show
and deferred on the balance sheet until the period in which the applicable
event is held. Direct show expenses are recognized in the period in which the
services are rendered.

NINE MONTHS ENDED FEBRUARY 28, 1998 COMPARED TO NINE MONTHS ENDED FEBRUARY 28,
1997
 
  Total revenue. MAGIC's revenue for the nine months ended February 28, 1998
increased $7.7 million, or 24.8%, to $38.7 million from $31.0 million for the
nine months ended February 28, 1997. This increase was due primarily to an
increase in the net square footage of exposition show space, consisting
principally of temporary floor space sold to fill a portion of MAGIC's
exhibitor backlog and an increase in the price per square foot charged to
exhibitors and revenue of $2.5 million from the introduction of MAGICKids.
 
  Direct costs. Direct costs for the nine months ended February 28, 1998
increased $0.4 million, or 2.8%, to $14.6 million from $14.2 million for the
nine months ended February 28, 1997. The increase was due to costs associated
with the increased revenue from MAGICKids.
 
  General and administrative expenses. General and administrative expenses for
the nine months ended February 28, 1998 increased $0.6 million, or 22.2%, to
$3.3 million from $2.7 million for the nine months ended February 28, 1997,
primarily due to increased salary and benefit costs related to an increase in
customer service and sales staff.
 
  Operating income. MAGIC's operating income for the nine months ended
February 28, 1998 increased $6.7 million, or 48.6%, to $20.5 million from
$13.8 million for the nine months ended February 28, 1997, due to growth in
revenue exceeding growth in expenses.
 
  Interest income. Interest income for the nine months ended February 28, 1998
decreased $0.1 million, or 12.5%, to $0.7 million from $0.8 million for the
nine months ended February 28, 1997, due to the reallocation of investments
from long-term investments to short-term liquid investments.
 
  Net income. Net income for the nine months ended February 28, 1998 increased
$4.2 million, or 45.2%, to $13.5 million from $9.3 million for the nine months
ended February 28, 1997, due to the increase in operating income, partially
offset by the related increase in income tax expense.
 
  EBITDA. EBITDA for the nine months ended February 28, 1998 increased $6.7
million, or 47.5%, to $20.7 million from $14.1 million for the nine months
ended February 28, 1997. This increase
 
                                      42
<PAGE>
 
was primarily due to increases in operating income as a result of increases in
the net square footage of exposition space sold and to the introduction of
MAGICKids.
 
FISCAL 1997 COMPARED TO FISCAL 1996
 
  Total revenue. MAGIC's revenue for fiscal 1997 increased $4.6 million, or
17.3%, to $31.2 million from $26.6 million in fiscal 1996. This increase was
due primarily to an increase in the net square footage of exposition floor
space, consisting principally of temporary floor space sold to fill a portion
of MAGIC's exhibitor backlog and an increase in the price per square foot
charged to exhibitors, a $0.4 million increase in revenue pursuant to the
acquisition of the Children's Trade Expo, and the introduction of new
advertising and promotional services.
 
  Direct costs. Direct costs for fiscal 1997 increased $1.5 million, or 11.5%,
to $14.5 million from $13.0 million for fiscal 1996. The increase was due to
higher rental and other expenses associated with temporary floor space (which
is substantially more expensive than permanent floor space) utilized by MAGIC
for its February 1997 events, partially offset by a reduction in certain other
facilities costs, including third party production costs.
 
  General and administrative expenses. General and administrative expenses for
fiscal 1997 increased $1.2 million, or 38.7%, to $4.3 million from $3.1
million for fiscal 1996. The increase was primarily due to increased general
and administrative expenses necessary to support MAGIC's increased revenue.
 
  Operating income. MAGIC's operating income for fiscal 1997 increased $2.1
million, or 21.2%, to $12.0 million from $9.9 million in fiscal 1996, due to
growth in revenue exceeding growth in expenses.
 
  Interest income. Interest income for fiscal 1997 increased $0.2 million, or
20.0%, to $1.2 million from $1.0 million in fiscal 1996, due to higher average
cash balances.
 
  Net income. Net income for fiscal 1997 increased $1.5 million, or 21.7%, to
$8.4 million from $6.9 million in fiscal 1996, due to the increase in
operating income partially offset by the related increase in income tax
expense.
 
  EBITDA. EBITDA for fiscal 1997 increased $2.0 million, or 19.6%, to $12.2
million from $10.2 million in fiscal 1996. This increase was primarily due to
increases in operating income.
 
FISCAL 1996 COMPARED TO FISCAL 1995
 
  Total revenue. Total revenue for fiscal 1996 increased $4.9 million, or
22.6%, to $26.6 million from $21.7 million in fiscal 1995. This increase was
due primarily to an increase in the net square footage of exhibition show
space, consisting principally of temporary floor space sold to fill a portion
of MAGIC's exhibitor backlog, an increase in the price per square foot paid by
exhibitors and increased revenue from exhibitor services and to fees related
to the Women's Wear Daily arrangement.
 
  Direct costs. Direct costs for fiscal 1996 increased $2.9 million, or 28.7%,
to $13.0 million from $10.1 million for fiscal 1995. The increase in direct
costs was primarily due to MAGIC's utilization of more expensive temporary
floor space to fill a portion of MAGIC's exhibitor backlog.
 
  General and administrative expenses. General and administrative expenses for
fiscal 1996 decreased $0.3 million, or 8.8%, to $3.1 million from $3.4 million
in fiscal 1995, primarily as the result of increased operating efficiencies.
 
  Operating income. MAGIC's operating income for fiscal 1996 increased $1.9
million, or 23.8%, to $9.9 million from $8.0 million in fiscal 1995, primarily
as a result of growth in revenue exceeding growth in expenses.
 
                                      43
<PAGE>
 
  Interest income. Interest income for fiscal 1996 increased $0.3 million, or
42.9%, to $1.0 million from $0.7 million in fiscal 1995.
 
  Net income. Net income for fiscal 1996 increased $1.4 million, or 25.5%, to
$6.9 million from $5.5 million in fiscal 1995, primarily due to the increase
in operating income, partially offset by an increase of $0.9 million in
MAGIC's income tax provision and a charge of $0.3 million for a loss on a
leasehold termination arising from MAGIC's administrative office relocation.
 
  EBITDA. EBITDA for fiscal 1996 increased $1.8 million, or 21.4%, to
$10.2 million from $8.4 million in fiscal 1995. The increase was primarily due
to a $1.9 million increase in operating income.
 
LIQUIDITY AND CAPITAL RESOURCES--MAGIC
 
  Cash flows from operating activities. Net cash provided by operations for
fiscal 1997 increased $2.4 million, or 33.8%, to $9.5 million from $7.1
million in fiscal 1996, primarily as a result of an increase in net income of
$1.5 million and an increase in accounts payable and accrued expenses of $0.9
million.
 
  Cash flows from investing activities. Net cash used in investing activities
in fiscal 1997 increased $1.2 million, or 35.3%, to $4.6 million from $3.4
million in fiscal 1996, primarily due to the acquisition of Children's Trade
Expo for $0.9 million and a $0.3 million increase in capital expenditures.
 
  Cash flows from financing activities. Net cash used in financing activities
for fiscal 1997 increased $1.5 million, or 53.6%, to $4.3 million from $2.8
million in fiscal 1996, primarily due to the repurchase of MAGIC's common
stock under a stock repurchase plan.
 
  Capital expenditures. Capital expenditures in fiscal 1997, fiscal 1996 and
fiscal 1995 totaled $0.4 million, $0.1 million and $0.3 million, respectively.
 
PRO FORMA LIQUIDITY AND CAPITAL RESOURCES--THE COMPANY
 
  After giving effect to the Pro Forma Adjustments, the Company's capital
structure will consist of (i) $210.0 million in senior term debt under the
Amended Credit Facility with $60.0 million available under the Revolving
Credit Facility, (ii) $150.0 million in aggregate principal amount of the
Notes and (iii) $179.0 million in common equity (including $70.0 million from
the HFCP III Equity Investment).
 
  Interest payments on the Notes and interest and principal payments under the
Amended Credit Facility will represent significant liquidity requirements for
the Company. The senior term debt consists of two tranches, (i) $85.0 million
of Tranche A Senior Term loans amortizing over 5.5 years and maturing
September 30, 2003, and (ii) $125.0 million Tranche B Senior Term loans with
modest amortization over the initial 5.5 years of its term maturing with
balloon payments in 2004 and 2005. Payment of the Revolving Credit Facility is
due September 30, 2003. Interest under the Amended Credit Facility is at 30,
60, 90 or 180-day LIBOR plus applicable margins ranging from 2.25% to 2.50%.
 
  The Company's other liquidity needs will be primarily for capital
expenditures and working capital. The Company's operations are not capital
intensive. Management anticipates that capital expenditures for 1998 and 1999
will be approximately $3.0 million and $3.5 million, respectively. The Company
currently operates with negative working capital.
 
  The Company's primary source of liquidity following the MAGIC Acquisition
and Refinancing is expected to be cash flow from operations. Additionally,
upon closing of the Amended Credit Facility, $60.0 million will be available
under the Revolving Credit Facility.
 
                                      44
<PAGE>
 
  The ability of the Company to fund its operations, make planned capital
expenditures and make scheduled payments on its indebtedness depends on its
future operating performance subject to future economic conditions and to
financial, business and other factors, many of which are beyond the Company's
control. See "Risk Factors." The Company believes that cash flow from
operations and available borrowings under the Revolving Credit Facility will
provide adequate funds for its working capital needs, planned capital
expenditures, debt services obligations (including the Notes) and other needs.
There can be no assurance that the Company's business will generate sufficient
cash flow from operations, or generate sufficient revenue growth, or that
future borrowings will be available to enable the Company to service its
indebtedness, including the Notes, or to fund its other liquidity needs.

  As of December 31, 1997, Advanstar had net operating loss carryforwards for
federal income tax purposes of approximately $12.0 million due primarily to
the increase in amortization of goodwill and other intangibles arising out of
the HFCP III Acquisition. The Acquisitions will not give rise to significant
additional amortization of intangibles for tax purposes. Consequently,
Advanstar expects the net operating loss carryforwards will begin to be
utilized in 1998 and fully utilized in 1999 or 2000 and its effective tax rate
will rise in 1999 and thereafter.
 
YEAR 2000 ISSUES
 
  The Company has conducted a review of its computer systems and software
infrastructure to identify those areas that are not Year 2000 compliant and
has begun implementing its plan to correct any shortcomings. Management
believes that with modifications or upgrades to existing software, Year 2000
compliance will not pose significant operational issues. The Company is also
conducting a review of its vendors' and suppliers' Year 2000 compliance.
Advanstar does not believe that any Year 2000 issues will have a material
adverse effect on its business, financial condition or results of operations.
 
ACCOUNTING PRONOUNCEMENTS
 
  In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income." The statement requires an enterprise
classify items of other comprehensive income by their nature in a financial
statement and display the accumulated balance of other comprehensive income
separately from retained earnings and additional paid-in capital in the equity
section of the statement of financial position. Advanstar adopted this
standard in first quarter 1998. Adoption of this standard did not have a
material effect on Advanstar in the first quarter of 1998.
 
  In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information." The
statement requires that a public business enterprise report financial and
descriptive information about its reportable operating segments such as a
measure of segment profit or loss, certain specific revenue and expense items,
and segment assets. Advanstar will adopt this standard during 1998 and is
currently analyzing the impact it will have on the disclosures in its
financial statements.

                                   BUSINESS
 
THE COMPANY
 
  The Company is a leading provider of global, multi-product marketing
communications solutions, principally through controlled circulation trade,
business and professional magazines and trade shows, expositions and
conferences. The Company also provides a broad range of other marketing
services products, including direct mail and database products and services.
The Company publishes 73 specialized business magazines and professional
journals and 30 directories and other publications. Of Advanstar's 55
magazines and journals for which competitive data is available, over 75% rank
either #1 or #2 in their respective markets (based on number of advertising
pages). The Company owns and manages 76 expositions and 29 conferences for
business, professional and consumer audiences worldwide, most of which are the
leading events in their respective national or regional markets. After giving
effect to the Pro Forma Adjustments, the Company would have derived 50.1% of
its 1997 revenues from publishing, 44.3% from expositions and conferences and
5.6% from marketing services. After giving effect to the Pro Forma
Adjustments, (i) the Company's 1997 revenue, EBITDA and EBITDA margin would
have been $247.3 million, $56.0 million and 22.7%, respectively; and (ii) the
Company's revenue, EBITDA and EBITDA margin for the first quarter ended March
31, 1998 would have been $79.6 million, $23.6 million and 29.6%, respectively.
EBITDA is not a measure of performance defined by GAAP and should not be
considered in isolation or as a substitute for net income or the statement of
cash flows which have been prepared in accordance with GAAP.
 
  The Company markets its broad range of products and services primarily
through four industry clusters in which it has developed critical mass and
expertise: (i) Retail, Hospitality & Fashion; (ii) Healthcare &
Pharmaceutical; (iii) Information Technology & Communications; and (iv)
Manufacturing & Processing. The Company believes its industry-focused cluster
structure allows it to cross-sell its products effectively, thereby capturing
a larger share of customer marketing expenditures. These four clusters are
further divided into 21 industry sectors. The Company has expanded its product
line within its clusters through new product introductions and strategic
acquisitions. These actions have enhanced the Company's position as a leading
provider of integrated business-to-business marketing communications
solutions. In addition, these actions have increased the Company's EBITDA by
leveraging its existing marketing and customer service infrastructure and
industry expertise.
 
  On April 30, 1998, Advanstar acquired MAGIC. MAGIC, organized in 1933,
produces MAGIC, the world's largest and most widely recognized trade show for
the men's apparel industry; WWDMAGIC, the largest women's apparel show in the
United States; and MAGICKids, a recently introduced children's apparel show.
The three shows are held concurrently in Las Vegas in February and August each
year. The February 1998 shows occupied an aggregate of approximately 505,000
net square feet of permanent floor space and 285,000 net square feet of
temporary floor space at the Las Vegas Convention Center and the Las Vegas
Hilton. Commencing with the August 1998 shows, the MAGIC trade shows will
occupy approximately 700,000 net square feet of permanent floor space at the
Las Vegas Convention Center and approximately 250,000 net square feet of
permanent floor space at the Sands Convention Center. The addition of the
Sands Convention Center will eliminate the need to use more costly temporary
space and will allow MAGIC to partially meet a long-standing backlog demand
for exhibit space. The February 1998 MAGIC trade shows attracted an audience
of over 80,000 attendees from over 100 countries, including major retailers,
such as Federated Department Stores, Nieman Marcus, Nordstrom's and Wal-Mart.
MAGIC's February 1998 trade shows included over 3,200 exhibitors (such as Levi
Strauss, Calvin Klein, Donna Karan and the Russell Corporation), representing
approximately 5,000 brand names. MAGIC's February 1996 and August 1996 trade
shows rank, respectively, as the 12th and 11th largest trade shows in the
United States. MAGIC's revenue, EBITDA and EBITDA margin for its fiscal year
ended May 31, 1997 were $31.2 million, $12.2 million and 39.3%, respectively.
For the nine months ended February 28, 1998, MAGIC's revenue, EBITDA and
EBITDA margin were $38.7 million, $20.7 million and 53.5%, respectively,
representing a revenue increase of 24.8% and an EBITDA increase of 47.4% over
the nine months ended February 28, 1997.

COMPETITIVE ADVANTAGES
 
  The Company believes that the following factors contribute to its strong
competitive position:
 
  Market Leadership. The Company has achieved a strong market position within
each of its four industry clusters primarily as a result of its ability to
offer customers in each cluster comprehensive and integrated marketing
communications solutions, consisting of leading publications, expositions and
marketing services. The Company publishes 73 specialized business magazines
and professional journals and 30 directories and other publications. Of
Advanstar's 55 magazines and journals for which competitive data is available,
over 75% rank either #1 or #2 in their respective markets (based on number of
advertising pages). The Company's largest magazines include Video Store,
CADALYST, Pharmaceutical Technology and Hotel & Motel Management. The Company
also owns and manages 76 trade shows and expositions and 29 conferences, most
of which are the leading events in their respective national or regional
markets. Many of the Company's expositions have commanding market presence:
for example, MAGIC is the #1 men's apparel trade show in the United States;
IBS New York is the #1 beauty show in the world; Telexpo is the #1
telecommunications trade show in Latin America; Artexpo New York is the #1
mid-market art fair in the United States; Dealernews International Powersports
Dealer Expo is the #1 trade show for the motorcycle industry; Licensing
International is the world's leading event for the international merchandise
licensing industry; and TeleCon is the leading event for the video
conferencing and long distance learning markets.
 
  Industry--Focused Integrated Marketing. In addition to offering a broad
range of products, the Company has developed a business model focused on
industry clusters to better serve its customers marketing communications
needs. This model facilitates the development of long-term relationships
between customers and dedicated Advanstar teams. These teams work with
customers to design and to implement all aspects of customized, business-to-
business marketing and communications programs, increasing cross-selling
opportunities across product and service groups. For example, the Company's
call center group, which is part of the Information Technology &
Communications cluster, recently concluded several multi-year marketing
contracts involving participation in the Company's trade shows and advertising
in the Company's trade publications.
 
  Diverse Customer Base. The Company's diverse customer base provides it with
stable and diverse sources of revenue and cash flow as well as an established
foundation from which to further penetrate existing markets and to develop new
markets. The Company's customer base is geographically diverse and crosses
many disparate industries, mitigating the Company's exposure to downturns in
particular geographic markets or industries. After giving effect to the Pro
Forma Adjustments, in 1997 the Company had over 14,000 advertisers and
exhibitors operating in over 20 different industry sectors, with no customer
or industry sector representing more than 1.1% or 13.7% of revenue,
respectively.
 
  Attractive EBITDA Margins and Modest Ongoing Capital Requirements. Consistent
with other leaders in the controlled circulation publication and trade show
industries, the Company enjoys attractive EBITDA margins and modest ongoing
capital expenditure requirements. The modest ongoing capital requirements result
in part from the Company's outsourcing of the printing of its trade publications
and the physical operation of its expositions. After giving effect to the Pro
Forma Adjustments, in 1997 the Company's operating cash flow (defined as EBITDA,
less capital expenditures) would have been $53.4 million or 21.6% of revenue. In
1997, the Company's capital expenditures were $2.6 million. After giving effect
to the Pro Forma Adjustments, the Company's operating cash flow for the first
quarter ended March 31, 1998 would have been $22.1 million, or 27.8% of revenue.
The Company's capital expenditures for the first quarter ended March 31, 1998
were $1.5 million.

  Experienced and Incentivized Management Team. The members of Advanstar's
senior management team have an average of over 15 years of industry
experience, with established track records in delivering revenue and profit
growth, developing new products, penetrating new markets
 
                                      47
<PAGE>
 
and integrating acquisitions. The Company's management is led by Robert L.
Krakoff, Chairman and Chief Executive Officer, James M. Alic, Vice Chairman
and Ira T. Siegel, Vice Chairman and Chief Operating Officer. Messrs. Krakoff
and Alic joined Advanstar in July 1996 and Mr. Siegel joined the Company in
May 1998. Prior to joining Advanstar, Mr. Krakoff was Chief Executive Officer
of Cahners Publishing and a Director of its parent company, Reed-Elsevier plc.
During Mr. Krakoff's 23-year tenure, Reed-Elsevier's exhibition business
became one of the largest worldwide exhibition management companies. Prior to
joining Advanstar, Mr. Alic served as Vice President and Controller of IBM
Corporation, and prior thereto was the Chairman of Reed Exhibition Companies.
Prior to joining the Company, Mr. Siegel was President and Chief Executive
Officer of LEXIS-NEXIS, a unit of Reed Elsevier, Inc. and prior thereto was
President and Chief Executive Officer of Reed Reference Publishing, another
division of Reed Elsevier, Inc. Messrs. Krakoff and Alic, collectively, have
invested $2.0 million in the business. Messrs. Krakoff and Alic and other
members of the Company's management, subject to vesting, have direct or
indirect interests in approximately 15% of the Common Stock on a fully diluted
basis.
 
BUSINESS STRATEGY
 
  The Company's business strategy is to grow profitability by solidifying its
position as a leading provider of comprehensive "one-stop" business-to-
business marketing communications solutions. The Company plans to achieve its
strategic objectives by (i) expanding its product and service offerings within
each of its industry sectors obtain a larger share of its customers' marketing
expenditures, (ii) selectively entering new industry sectors and (iii)
leveraging the strengths of its centralized administrative and production
operations.
 
  Expand Product Offerings. The Company plans to "fill-in" its product and
service offerings within its existing industry sectors through selective
acquisitions and joint ventures, strategic new product launches and
international expansion.
 
  . Selective Acquisitions and Joint Ventures. The Company intends to
    continue to engage in strategic acquisitions and joint ventures within
    its existing industry sectors. The Company believes it can improve its
    competitive position through such acquisitions by (i) applying its
    extensive industry experience to enhancing the performance of newly
    acquired businesses, (ii) integrating acquisitions and joint ventures
    into its cost-efficient infrastructure, (iii) cross-selling new products
    and services with existing products and services and (iv) using new
    products and services to increase visibility within its markets. Since
    the HFCP III Acquisition and excluding the MAGIC Acquisition, Advanstar
    has completed or expects to complete 19 acquisitions and joint ventures
    for purchase prices aggregating approximately $130.8 million in the
    information technology, telecommunications, beauty, travel, entertainment
    and call center sectors.
 
  . Strategic New Product Launches. The Company has successfully developed
    new products within its existing industry clusters and will continue to
    make strategic new product introductions. In 1997, the Company launched
    seven magazines and seven expositions and conferences in existing
    industry sectors to fill-in its existing product offerings. For example,
    in 1997 the Company launched WorldPharm, a pharmaceutical industry
    exposition to be held in Philadelphia in 1998, to complement its strong
    position in pharmaceutical publishing.
 
  . International Expansion. The Company intends to enhance its position in
    international markets by leveraging its widely recognized brands, its
    experience in international operations and its current customers' demand
    for increased global marketing. The Company currently has operations in
    Canada, the United Kingdom, Hong Kong and Brazil and intends to expand
    further internationally through the extension of existing products into
    new geographic markets, joint ventures with local operating partners and
    selective acquisitions. Many of the Company's existing international
    products are regional in nature (Pan European, Pan Asian or Pan Latin
    American), and future expansion is expected to follow this model. For
    example, in mid-1997,
 
                                      48
<PAGE>
 
   building on its existing strength in the U.S. and Asian telecommunications
   markets, Advanstar acquired two magazines and 13 conferences serving the
   Brazilian and Latin American telecommunications markets and, in early
   1998, acquired Telexpo, the largest Latin American telecommunications
   trade show.
 
  Selectively Enter New Industry Sectors. The Company will selectively enter
new industry sectors in which it believes it can become a leading participant
and achieve attractive margins. For example, the MAGIC Acquisition presented
Advanstar with an ideal opportunity to enter the U.S. men's apparel market
with critical mass and to increase revenue and reduce expenses by leveraging
Advanstar's extensive trade show experience.
 
  Leverage Cost-Effective Centralized Administrative and Production
Facilities. The Company believes that its organizational structure (i)
provides continuing opportunities to produce attractive margins through
centralized functional cost management, (ii) provides a platform to easily
introduce new titles or expositions based on existing products, and (iii)
facilitates integration and cost reductions with respect to acquired titles
and expositions. The Company has a long established and highly efficient
centralized publishing infrastructure in both the U.S. and Europe. The Company
focuses on continually improving its systems and processes to provide
effective, low cost operations in circulation, fulfillment, production and
print and paper vendor management. Similar cost-efficient infrastructures are
being established in Asia and in Latin America. In 1997, a centrally managed
exhibition operations function was established in both the U.S. and Europe to
provide consistency of business process and cost effective delivery of these
services. Centralized support also exists in finance and accounting,
information technology and communications, human resources and strategic
planning.
 
INDUSTRY OVERVIEW
 
  Trade Publications. Trade publications provide key new product or
educational information to readers and a periodic medium for advertisers to
reach highly targeted and select business audiences throughout the year. Trade
publications are generally supported by advertising and are often circulated
free-of-charge. The most effective and profitable publications are those with
readership that includes a high proportion of the individuals who influence
purchasing decisions in a market niche, while avoiding the expense and
inefficiency of circulating to individuals who are not clearly within the
target groups. The U.S. trade publication industry is expected to grow at a
compound annual growth rate of 5.9% between 1995 and 2000, increasing from a
total market size of approximately $7.7 billion in 1995 (consisting of
approximately $5.9 billion in advertising and approximately $1.8 billion in
subscriptions) to approximately $10.2 billion in 2000 (consisting of
approximately $8.2 billion in advertising and approximately $2.0 billion in
subscriptions).
 
  Expositions and Trade Shows. Expositions and trade shows allow exhibitors a
cost-effective means to showcase and sell products and services and to develop
business relationships with many potential customers in a short time period,
while providing attendees an opportunity to view a broad range of products as
well as to interact with numerous suppliers at once. A 1996 study noted that
the cost of closing a sale with a trade show prospect is less than 50% of the
cost of closing a sale in the field. The number of U.S. expositions grew from
approximately 3,300 events in 1989 to approximately 4,400 events in 1996, a
33.8% increase. The amount of net square feet of U.S. expositions grew 65.9%
between 1989 and 1996, from approximately 270 million net square feet in 1989
to approximately 448 million net square feet in 1996. Attendance at U.S.
expositions has grown from approximately 60 million attendees in 1989 to
approximately 101 million attendees in 1996.
 
PRODUCTS AND SERVICES
 
  The Company provides its products and services to selected industries, which
are grouped into broader industry-related clusters. The clusters are supported
by one centralized administrative support and production facility within each
region of the world.
 
                                      49
<PAGE>
 
  Within each cluster, Advanstar provides a comprehensive set of marketing
communications products, services and support geared to the particular
industry's marketing and customer needs. The Company provides advertising,
expositions, conferences, direct mail services, custom publishing and
research, database marketing programs, focus groups, market research,
reference books, internet services and other services to facilitate its
clients' business-to-business marketing and communications programs.
 
  The Company's publications generally are controlled circulation, business-
to-business trade publications which are distributed free-of-charge to
qualified company-related recipients and generate revenues predominantly from
the sale of advertising space. Because Advanstar offers its advertisers access
to a highly targeted and industry-specific subscriber base, it is able to sell
advertising space in its publications at rates that are higher than the
average rates charged by publications aimed at more general audiences. The
Company seeks to increase advertising revenues by introducing current
advertisers to new titles, by attracting new advertisers targeted at the
Company's readership and by developing new reader and advertising categories
in both print and electronic editions.
 
  Another central aspect of the Company's overall product offerings is its
leading expositions and conferences. In 1997, the Company held over 90
expositions and conferences. Events usually include an extensive conference
program, which provides a forum for the exchange and dissemination of
information relevant to the particular event's focus. In addition, each event
typically has one or more keynote speakers drawn from industry leaders.

 Retail, Hospitality & Fashion
 
  Advanstar's Retail, Hospitality & Fashion industry cluster serves the
fashion, art, beauty, travel and hospitality, entertainment, marketing and
motor vehicle industry sectors with a full range of publications, expositions
and conferences and marketing services.
 
  On April 30, 1998, Advanstar acquired MAGIC. MAGIC, organized in 1933,
produces MAGIC, the world's largest and most widely recognized trade shows for
the men's apparel industry; WWDMAGIC, the largest women's apparel show in the
United States; and MAGICKids, a recently introduced children's apparel show.
The three shows are held concurrently in Las Vegas in February and August each
year. The February 1998 shows occupied an aggregate of approximately 505,000
net square feet of permanent floor space and 285,000 net square feet of
temporary floor space at the Las Vegas Convention Center and the Las Vegas
Hilton. Commencing with the August 1998 shows, the MAGIC trade shows will
occupy approximately 700,000 net square feet of permanent floor space at the
Las Vegas Convention Center and approximately 250,000 net square feet of
permanent floor space at the Sands Convention Center. The addition of the
Sands Convention Center will eliminate the need to use more costly temporary
space and will allow MAGIC to partially meet a long-standing backlog demand of
800 exhibitors. The February 1998 MAGIC trade shows attracted an audience of
over 80,000 attendees from over 100 countries, including major retailers, such
as Federated Department Stores, Nieman Marcus, Nordstrom's and Wal-Mart.
MAGIC's February 1998 trade shows included over 3,200 exhibitors (such as Levi
Strauss, Calvin Klein, Donna Karan and the Russell Corporation), representing
approximately 5,000 brand names. MAGIC's February 1996 and August 1996 trade
shows rank, respectively, as the 12th and 11th largest trade shows in the
United States. MAGIC's revenue, EBITDA and EBITDA margin for its fiscal year
ended May 31, 1997 were $31.2 million, $12.2 million and 39.3%, respectively.
For the nine months ended February 28, 1998, MAGIC's revenue, EBITDA and
EBITDA margin were $38.7 million, $20.7 million and 53.5%, respectively,
representing a revenue increase of 24.8% and an EBITDA increase of 47.4% over
the nine months ended February 28, 1997.
 
  In the art sector, the Company serves buyers and sellers of mid-market
original art and high quality prints and posters. Advertising revenue of Art
Business News is a publication written for the gallery owner and art dealer
with a circulation of approximately 31,000. The Company's Artexpo New York is
the largest mid-market art show in the world, with approximately 133,000 net
square feet utilized at the Javits Convention Center in New York for the 1998
show. Total revenue from this event grew 49.3% in 1998 compared with 1997. The
Company intends to grow by introducing regional Artexpo shows in new cities
(Artexpo Los Angeles already exists), covering additional art market segments
in both magazines and shows (a trade only print and poster segment was added
to Artexpo in 1998), cross-selling between the art shows and the magazine, and
attracting additional international advertisers and exhibitors to the U.S.
market.
 
  In the professional beauty and hair care sector, the Company is a leading
provider of marketing communications services to those vendors (e.g.,
Sebastian, Clairol and Nexxus) wishing to reach the salon owner, beautician
and hair care professional. The Company's magazine in this market is American
Salon, the #2 publication in the field as measured by number of advertising
pages. American Salon reaches a circulation of approximately 125,000. The
Company's IBS New York Show is the market leading exhibition and educational
event for the salon audience, with over 41,000 attendees and over 400
exhibiting companies occupying in excess of 100,000 net square feet of exhibit
space at the Javits Convention Center, New York each year in March. The
Company has seven additional IBS shows which, together with IBS New York,
occupy approximately 250,000 net square feet of exhibit space and attract
approximately 61,000 attendees. The IBS brand has a strong international
reputation and, in addition to continued strong international attendance at
U.S. shows, the Company believes there is opportunity to extend this brand
into international markets.

  In the travel and hospitality sector, the Company has two main products--
Hotel & Motel management ("HMM"), and PREMIER HOTELS AND RESORTS, a twice-a-
year directory for the high-end travel agent market. HMM is the third largest
magazine in the Company's portfolio and has established a #2 position in both
readership and number of advertising pages in the hospitality management
market. It is generally published semi-monthly and is distributed to a
circulation of approximately 55,000 hotel managers, owners and developers.
PREMIER HOTELS AND RESORTS was launched in 1996 to provide the high-end travel
agent market in the U.S. with a high quality directory of worldwide four and
five star hotels and resorts. In 1997, PREMIER HOTELS AND RESORTS generated
628 advertising pages.
 
  The major products in the entertainment and marketing sector are in the home
video market and the merchandise licensing market. The Company's largest
revenue magazine is Video Store, a weekly publication circulated to home video
retailers. Video Store is the #2 magazine in the field and generated
approximately 1,300 advertising pages in 1997. While the video retailing
sector may be mature, the competition for retail shelf space and the emergence
of new formats (such as digital video disks) are expected to sustain the
advertising market for many years. In February 1998, the Company contributed
its East Coast Video Show, a 40,000 square foot regional show for home video
retailers, to a 50/50 joint venture, called Home Video Entertainment Events,
with the Video Software Dealers Association, the operators of a 100,000 net
square foot annual event in Las Vegas. The venture intends to expand to other
home video events in North America and overseas.
 
  In the merchandise licensing sector, the Company produces Licensing
International, the leading exhibition bringing together the owners and
developers of intellectual property and brands with the product developers and
merchandisers of licensed products. Sources of licensing include film and TV,
sports leagues and teams, major consumer product brands, and art and image
licenses. The total licensing market has been estimated at $120 billion in
licensed merchandise by the Licensing Industry Merchandisers Association, the
sponsor of the exhibition. Leveraging this show's strength, the Company
recently entered into a joint venture with Wideband, Inc. which publishes
Li(C)ense! to serve this large and rapidly growing worldwide market.
 
  In the motor vehicle sector, the Company's strength is in the powersports
segment (motorcycles, snowmobiles, and personal watercraft). The Company's
exhibition portfolio includes events for each level of trade in the market--
nine consumer motorcycle shows in major metropolitan U.S. cities, the largest
aftermarket accessories show for motorcycle dealers, and a distributor event
for introduction of new product to the distribution channel. The Company's
position in this market is supported by its market leading controlled
circulation magazine, Dealernews, which is targeted at the powersports
retailer and supported by aftermarket product suppliers.
 
 Healthcare & Pharmaceutical
 
  The Company's portfolio in healthcare publishing includes ten high quality,
professionally respected magazines. Within the group, selected titles include
Geriatrics, Formulary, Dermatology Times, Ophthalmology Times and the leading
magazine for veterinarians, dvm THE NEWSMAGAZINE OF VETERINARY MEDICINE. In
contrast to the Company's business-to-business publishing, where circulation
is a competitive measure, all healthcare publications use circulation lists
supplied by the American Medical Association, thereby making readership the
primary competitive yardstick used by advertisers in this market. Among the
relevant segment competitors, Formulary, dvm THE NEWSMAGAZINE OF VETERINARY
MEDICINE and Geriatrics are each #1 or #2 in terms of readership and number of
advertising pages.
 
  The Company serves the pharmaceutical sector in areas such as research and
development, manufacturing, packaging and marketing through a series of market
leading publications and
 
                                      55

conferences. Each of the Company's five publications in this market are #1 or
#2 in their respective market segments, based on number of advertising pages.
The Company's leading magazine in this market is Pharmaceutical Technology,
the Company's second largest magazine and the #1 publication in its field.
Published monthly and circulated to approximately 32,000 pharmaceutical
scientists, engineers and operations managers, Pharmaceutical Technology
generated 1,250 advertising pages in 1997. The Company built on this success
by launching Pharmaceutical Technology Europe, Pharmaceutical Technology Asia,
a related pharmaceutical technology buyer's guide, and a series of U.S. and
European conferences. Based upon this market strength, the Company launched a
major exhibition, WorldPharm, to be held for the first time in Philadelphia
during September 1998. Research is underway to extend the WorldPharm concept
to international markets. The Company also publishes PHARMACEUTICAL EXECUTIVE,
the leading magazine for product managers and marketing professionals within
pharmaceutical companies. As government regulation of this area becomes more
permissive, these professionals are increasingly targeting advertising and
promotion directly to consumers. Although approximately $1 billion was spent
in 1997 by pharmaceutical companies on direct to consumer marketing efforts,
product managers and marketing professionals have little training or
experience in consumer advertising and marketing, as their efforts have
historically been targeted at the doctor. PHARMACEUTICAL EXECUTIVE intends to
fill this need for education, research and information through a special
edition, starting initially as a supplement to PHARMACEUTICAL EXECUTIVE but
expanding to a stand-alone publication if market response is positive. The
first DTC Times supplement will be published in May, 1998.
 
 Information Technology & Communications
 
  Advanstar's Information Technology & Communications industry cluster serves
the global telecommunications, information technology and call center/computer
telephony industries with a wide range of publications, exhibits and
conferences and marketing services.
 
  In the information technology sector, the Company is a highly targeted niche
publisher and exhibition organizer. The Company's largest information
technology publication, CADALYST, serves end users, managers and executives in
the Autodesk design and visualization industry, which includes AutoCAD and
related technologies. In 1997, CADALYST held the #1 market position in its
sector, based on number of advertising pages. Circulation totals slightly over
80,000, 30% of which is paid subscription. Another significant publication in
this group is PC Graphics & Video, a monthly magazine covering PC "platform"
applications involving digital graphics creation and digital video capture and
manipulation. Developers and users involved with graphics creation and
manipulation are shifting to the PC platform for future investments in
hardware and software, and PC Graphics & Video is their information and
marketing vehicle. Advertising pages grew by 21.0% in 1997 to approximately
570 pages. A directly related trade show and conference, Digital Content
Creation, has been launched by the Company and is planned for late 1998 in Los
Angeles. The largest existing trade exhibition in this group is the On Demand
Digital Printing and Publishing Conference and Expo. This exhibition was built
on the transition of traditional printing to a digital environment and
comprises approximately 80,000 net square feet. Major exhibitors include Xerox
Danka, Moure and IBM. The event is four years old and continues to expand
rapidly, growing approximately 30% from 1996 to 1997. The other events in the
group, including: iEC (internet & electronic commerce) and Healthcare
Information Technology, which is planned for launch in Boston in late 1998,
are 50/50 partnerships with the Gartner Group, the leading information
technology research and consulting group.
 
  The rapidly evolving, newly competitive telecommunications sector is one of
the Company's most important and fastest growing targeted markets. The largest
and oldest publication in the Company's telecommunications portfolio is
America's Network, serving the telephone, cable TV and wireless
telecommunications industries. With a qualified circulation of approximately
50,000, America's Network is the #2 publication in its niche and generated
approximately 730 advertising pages in 1997. As most of the major vendors
operate globally (Ericcson, Lucent and GTE), the Company's growth strategy has
 
                                      56
<PAGE>
 
been focused on increasing coverage of international markets. Advanstar
purchased the remaining interest of its minority partner in TELECOM ASIA and
Telecom China in late 1997, providing a wholly-owned platform to accelerate
growth in this region. In mid-1997, the Company acquired Telepress, a
Brazilian based publisher and conference organizer. In February 1998, the
Company acquired Telexpo, the largest telecom exhibition in Latin America. In
May 1998, the Company acquired the leading expositions and conferences for the
video conferencing and long distance learning industries,TeleCon.
 
  Through its global reach and rapid growth, the Company's call center and
computer telephony sector serves as a primary example of the Company's
successful market-focused expansion strategy. The market is driven by the
integration of computers and traditional telephony into products such as
interactive voice response, automated phone answering and intelligent call
distribution. Principal applications are in customer service centers, help
desk operations and telemarketing, generally grouped under the term "call
centers." The Company has two market leading publishing properties, Voice+, a
pan-European magazine, and Voice+ Asia Pacific to provide a more comprehensive
product offering. In March 1998, the Company acquired Teleprofessional, the #3
U.S. publication in this market, which the Company believes is the fastest
growing publication in this field. The group also includes a series of market
leading exhibitions and conferences in the U.S., Canada, Europe, Asia and
Australia. Incoming Call Center Management Conference & Exhibition, the
largest U.S. event in this market, attracted approximately 1,400 conferees at
the most recent event. The other U.S. event, Call Center Conference &
Exhibition is held annually in February and grew 26.6% from 1997 to 1998. The
largest event in the group, Voice Europe (UK), grew 39.6% in 1997 compared to
1996. The Company also has Voice shows in Germany and Singapore and call
center events in Amsterdam, Sydney and Toronto.
 
 Manufacturing & Processing
 
  Within the application technology sector, the Company's strongest and
largest position is in the field of automatic data capture, identification and
tracking systems (bar coding, magnetic stripe, smart cards, biometrics and the
associated systems). Automatic ID NEWS is the #2 publication in the U.S. and
"sister" publications of the same name are market leaders in Europe, Asia and
Latin America. The Company expects that growth in this market will come from
new technologies (radio frequency applications for mobile applications),
deeper penetration into medium-sized and small firms and from the increasing
integration of the data capture and identification functions into enterprise-
wide systems and supply chain management. The Company also operates the #1
trade show and conference in the U.S., SCANTECH, and the market leading trade
show in Europe, SCANTECH EXPO Europe.
 
  The Company serves the scientific instrumentation sector through four market
leading publications LC.GC (liquid and gas chromatography), LC.GC
International (a pan-European magazine), LC.GC Asia Pacific and Spectroscopy.
In total, the science group generated 1,262 advertising pages in 1997, up 9.7%
from 1996. The Company believes that exhibitions and conferences are a growth
opportunity and, as a result, is broadening Pharm Analysis Europe to cover a
wider range of applications and renaming the broadened event ChemAnalysis
Europe.
 
  The OEM and processing sector is a grouping of publications, exhibitions and
conferences that focus on equipment, materials and intermediate products used
in the manufacturing and processing of a wide range of products. Magazines in
this market include DCI (cosmetic, toiletry, OTC drugs and personal care
product manufacturing), Medical Device TECHNOLOGY (pan-European) and PIT &
QUARRY (aggregates extraction and processing). Exhibitions and conferences
include three regional plastics exhibitions, each running on a two year on and
one year off cycle, market leading Medical Device Technology Trade Show &
Conference events in Europe and two Sensors Expos.

 Market Development
 
  The Company has grouped the balance of its products and services into a
Market Development cluster to provide focus on growth through internal
development or acquisition. This group addresses large and attractive markets
(i.e., energy, landscape management, printing, roofing and construction) in
which the Company does not yet have critical mass. For example, in the fashion
and apparel market, the Company's only participation prior to the MAGIC
Acquisition, was in the intimate apparel segment through the market leading
magazine BFiA (body fashion/intimate apparel). This magazine and its related
products will join the MAGIC trade shows in the Retail, Hospitality & Fashion
cluster and, management believes, will grow significantly through its
relationship with MAGIC.
 
COMPANY OPERATIONS
 
  Publications. The Company has an established and efficient publishing
infrastructure in the U.S. and Europe. The Company's publications generally
follow the controlled circulation model. Recipients are targeted through
market research to determine the market coverage and purchasing authority
desired by prospective advertisers. Based on existing and acquired mail lists,
the targeted recipient is then solicited through promotions offering free
subscriptions to the relevant publications. High quality circulation is
achieved when a high percentage of the circulation list is recently qualified
(within one or two years) and the publication is delivered at the direct
request of the recipient. Recipients are qualified and re-qualified on a
regular basis through both direct mail and through qualification cards
included in the publication. The Company maintains highly experienced and
efficient circulation management teams in Duluth, Minnesota, Eugene, Oregon
and Chester, United Kingdom. The Company believes that its circulation lists
for its U.S. and European publications provide the market coverage and buying
power desired by the Company's advertising customers.
 
  Advertising sales and editorial functions are dispersed throughout the U.S.,
Asia, Brazil, Europe and the U.K. Advertising sales are predominantly executed
by the Company's employees. Editorial content for the Company's publications
is primarily staff-written, with some editorial contribution by freelance
writers and industry or professional participants in selected markets.
 
  The Company believes it is highly efficient in all functions related to the
production of its publications. Advertising materials and editorial content
are integrated in the Company's Duluth and Chester production facilities,
where layout, ad insertion and output to film is completed. All printing is
outsourced to vendors in various regions, but printing contracts are
negotiated and managed centrally. The Company purchases paper centrally
through a relationship with one of the industry's largest paper brokers. This
broker ships paper directly from the mills to the printers at the Company's
request. The Company maintains its own central U.S. fulfillment operations in
Duluth to generate mailing labels and mailing instructions for the printers.
The Company's workforce is highly experienced and is based in relatively low-
cost locations in Duluth and Chester. The Company is establishing the same
back-office infrastructure in both Latin America and Asia.
 
  Expositions and Conferences. The operational model for exhibitions and
conferences is quite different from publishing, due to the physical nature of
the product and the time cycle for event planning and execution. Basic
positioning and sales and marketing strategy is decided before each event--as
much as 18 months in the case of new launches and typically more than one year
for recurring events. In many cases, venue and hotel plans must be made
several years in advance, particularly for primary markets such as New York,
Chicago, Las Vegas, Los Angeles and San Francisco.
 
  The sales cycle for any recurring show typically begins shortly before the
preceding show, with pricing, preliminary floor plans, and exhibitor promotion
mailed in advance so that active selling can begin in person at the
exposition. Typically, this active selling includes taking booth reservations
and/or contracts and small deposits for the future show. The space selection
process is generally handled on
 
                                      58
<PAGE>
 
a priority point system, combining exhibiting history and booth size. Certain
of the Company's shows (Dealernews or Call Center, for example) sell over 80%
of their exhibit space before the preceding event is over. The sales cycle
continues with selling to new exhibitors, resolving customer service requests
and collecting progress payments. Typically, customer payments are received in
full before the show begins.
 
  In addition to the sale of exhibit space, exhibitors are offered a wide
range of promotional opportunities to raise their visibility at an event.
These can include directory and preview advertising, banners, sponsorships of
various functions, and a wide variety of other products or services.
 
  Conferences linked to exhibitions play a crucial strategic role in
exhibition development. A conference represents the "editorial" for an event,
which can be used to build new segments, raise the profile of particular
segments or technologies and drive attendance. Conference development is led
by Company personnel with the support of editorial staff and industry experts.
 
  Operationally, the Company functions in a capacity similar to a general
contractor. Venues, hotels, and vendors for decorating, registration, travel
and housing, audio-visual services and other services are selected and managed
by Company personnel in central exposition operations. While the production of
a show may ultimately involve hundreds of workers on site, very few of these
are Company employees, thus minimizing overhead and permanent staffing costs.
 
  Attendee and conference promotion is the largest single expense in producing
trade shows, expositions and conferences. Promotion is primarily undertaken
through direct mail, using both in-house and rented lists of pre-qualified
industry participants and the cooperative efforts of exhibitors. Where the
Company also has publications in the field, the magazines play a key role by
providing lists from circulation files and providing editorial coverage for
the upcoming show. Other industry magazines are also involved as the event
goal is to represent the entire industry. Relationships with publications are
normally based on an exchange of show ads and lists for booth space and on-
site visibility. The "show issue" of an industry magazine for a related event
is often the biggest issue of the year, as the advertisers want to reinforce
their show presence by making sure attendees know they will be prominent at
the show. Show attendance is typically free for pre-registered attendees, with
modest fees for on-site registrants. Conference attendance can be a
significant revenue source, with courses or full session pricing ranging from
less than $100 to over $1,000, depending on the content being delivered and
competitive pricing.
 
COMPETITION
 
  Competition for Advanstar's products and services is highly fragmented, both
by product and geography, and exists at many levels. On a global level, there
are several much larger international firms--such as Reed Elsevier and United
News and Media--which operate in many geographic markets and have broad
product offerings in publishing, expositions and conferences and marketing
services. Many of these competitors are better capitalized and have
substantially greater financial and other resources than the Company. In a few
cases, these firms operate in the same market as the Company. In general,
these large firms are organized and market their products and services by
product and geographic location, not on an integrated basis.
 
  Within each particular industry sector, the Company generally has a large
number of direct and indirect competitors. In some cases, these competitors
operate in several geographic areas. In other cases, they operate in only one
geographic market. In most cases, these competitors are small to medium-sized
corporations. However, in several industries markets such as information
technology and healthcare, there are large competitors focused on a single
industry. In expositions and conferences in particular, there are many not-
for-profit association competitors and, in several countries, the exposition
hall owner and operator may also be a competitor.
 
                                      59
<PAGE>
 
  In any given publishing marketplace in a particular country, there are
typically two to five direct competitors for both readers and advertisers.
Additionally, there are usually many indirect competitors who define market
segments differently and thus may be alternatives for either the reader or the
advertiser.
 
  Exposition and conference competition in each market and country occurs on
many levels. There is seldom any truly direct competitor for a particular
event, given the uniqueness of venue and date. However, given the availability
of alternative venues and the ability to define events for particular market
segments and/or with different strategic positioning, the range of competition
for exposition dollars, sponsorships and show attendees and conferees is
extensive. Because there are few barriers to entry, the Company anticipates
that, as the trade publications and expositions industries evolve, additional
competitors with greater resources than the Company may enter the markets, or
particular segments of the markets, thereby intensifying competition.
 
INTELLECTUAL PROPERTY
 
  The Company has developed strong brand awareness for its principal products
and services. Accordingly, the Company considers its trademarks, servicemarks,
copyrights, trade secrets and similar intellectual property as important to
its success and relies on trademark, servicemark, copyright and trade secret
laws, as well as licensing and confidentiality agreements, to protect its
intellectual property rights. The Company generally registers its material
trademarks and servicemarks in the United States and in certain other key
countries in which these marks are used. Effective trademark, servicemark and
trade secret protection may not be available in every country in which the
Company's products and services are available.
 
EMPLOYEES
 
  As of May 31, 1998, the Company had approximately 1,200 full-time employees.
None of the Company's U.S. employees is represented by a labor union. The
Company considers its relationships with its employees to be good.
 
FACILITIES
 
  The Company's finance and administration, circulation, fulfillment,
production and other necessary operational support facilities are located in
Duluth, MN. The Company has executive marketing, sales and editorial offices
in other cities in the United States, including Boston (MA), Cleveland (OH),
New York (NY), Edison (NJ), Eugene (OR), Fairfield (CT), Chicago (IL), Santa
Ana (CA), Waterloo (IA), Woodland Hills (CA) and Brentwood (CA). In addition,
the Company has offices in Sao Paulo and Rio de Janiero, Brazil; Hong Kong,
China; and Chester, United Kingdom.
 
  The Company generally leases its offices from third parties. In addition,
the Company owns its operations offices in Duluth, Minnesota and Cleveland,
Ohio. The Company believes that its properties are in good operating condition
and that suitable additional or alternative space will be available on
commercially reasonable terms for future expansion.
 
LEGAL PROCEEDINGS
 
  The Company is not a party to any legal proceedings other than ordinary
course, routine litigation which is not material to the business, financial
condition, or results of operations of the Company.

(1) The options granted are subject to a five-year vesting schedule pursuant
    to which the options vest in 20% increments on each anniversary of the
    date of grant. On May 31 of each year, the exercise price per option
    increases by 10% over the previous year's exercise price. The exercise
    price per option increases by a pro rated amount of such 10% increase in
    the case of exercises which do not occur on May 31.
(2) Amounts reported in these columns represent amounts that may be realized
    upon exercise of the options immediately prior to the expiration of their
    term assuming the specified compounded rates of appreciation of the Common
    Stock over the term of the options. The exercise prices of the options
    increases 10% per year over the life of the option. These numbers are
    calculated based on rules promulgated by the Securities and Exchange
    Commission (the "Commission") and do not reflect the Company's estimate of
    future stock price growth. Actual gains, if any, on stock option exercises
    and Common Stock holders are dependent on the timing of such exercises and
    the future performance of the Common Stock. There can be no assurance that
    the rates of appreciation assumed in this table can be achieved or that
    the amounts reflected will be received by the individuals.
(3) As of December 31, 1997, Mr. Farber had been granted options to purchase
    an aggregate of 132,900 shares of Common Stock, 23,300 of which are
    exercisable within 60 days of May 31, 1998.
(4) As of December 31, 1997, Mr. Montgomery had been granted options to
    purchase an aggregate of 90,000 shares of Common Stock, 16,000 of which
    are exercisable within 60 days of May 31, 1998.

CERTAIN PLANS AND EMPLOYMENT AGREEMENTS
 
  Stock Option Plan. Holdings' 1996 Stock Option Plan (the "1996 Plan")
provides for the issuance of a maximum of 745,200 shares of Common Stock
pursuant to the grant of non-qualified stock options to employees and other
individuals who render services to Holdings or the Company.
 
  The 1996 Plan is administered by the Board of Directors. Subject to the
provisions of the 1996 Plan, the Board of Directors has the authority to
determine the terms of options granted, including the authority to: (i)
determine to whom options may be granted; (ii) determine the time or times at
which options shall be granted; (iii) determine the exercise price of shares
subject to each option; (iv) determine the time or times when each option
shall become vested and exercisable and the duration of the exercise period;
(v) extend the period during which outstanding options may be exercised; (vi)
determine whether restrictions such as repurchase options are to be imposed on
shares subject to options and the nature of such restrictions, if any; and
(vii) interpret the 1996 Plan and prescribe and rescind rules and regulations
relating to it. The 1996 Plan provides that the Board of Directors will take
whatever actions it deems necessary, under Section 422 of the Internal Revenue
Code of 1986, as amended, and the regulations promulgated thereunder, to
ensure that options granted under the 1996 Stock Plan are not treated as
"incentive stock options".
 
  With the exception of the options granted to Mr. Loggia, each option granted
as of May 31, 1998 is subject to a five-year vesting schedule pursuant to
which the options vest in increments of approximately 20% on each of the first
five anniversaries of the date of grant. Prior to an initial public offering
of Holdings, each outstanding option shall become fully exercisable in the
event of a "change of control." A "change of control" means the acquisition by
any person or group of persons (other than an affiliate or affiliates of HFCP
III) of more than 50% of the outstanding shares of Common Stock or shares of
capital stock constituting more than 50% of Holdings' voting capital stock, or
of all or substantially all of Holdings' assets. The Board of Directors may,
in its discretion and in accordance with the provisions of the 1996 Plan,
accelerate the vesting of any option.
 
  In addition, each share to be acquired upon exercise of an option is subject
to Holdings' right to repurchase all but not less than all of such shares.
Holdings may exercise its right of repurchase upon the occurrence of any of
the following: (i) the termination of the optionee's relationship with
Holdings for any reason; (ii) the receivership, bankruptcy or other creditor's
proceeding regarding the optionee or the taking of shares acquired upon
exercise of an option by legal process; (iii) distribution of shares acquired
upon exercise of an option to the optionee's spouse pursuant to a decree of
dissolution, operation of law, divorce or any other reason, except as may be
permitted by the Holdings; or (iv) a breach of the optionee's duty not to
compete or solicit any employee of Holdings or its affiliates within one year
of the termination of the optionee's relationship with Holdings. Upon the
occurrence of a repurchase event, Holdings may exercise its repurchase right
within sixty days following the later of the date of the exercise of options
or the date Holdings receives actual knowledge of a repurchase event. Subject
to certain exceptions, the repurchase price of the shares (if terminated other
than for cause), is fair market value as determined pursuant to the 1996 Plan.
 
  As of May 31, 1998, options to purchase 710,400 shares of Common Stock at an
average exercise price of $12.10 were outstanding under the 1996 Plan, and no
options had been exercised.
 
  401(k) Plan. Holdings has an Employees' 401(k) Plan and Trust (the "401(k)
Plan"). All current and future employees who have completed one year of
service with Holdings, the Company or any other domestic subsidiary of
Holdings and are at least 21 years of age are eligible to participate in the
Plan. Participants in the 401(k) Plan may not contribute more than the lesser
of a specified statutory amount ($9,500 in 1997) or 15% of his or her pre-tax
total compensation. Holdings is required to cause to be made a matching
contribution to the 401(k) Plan in accordance with the following schedule: (1)
with respect to the employee's elective contribution in an amount up to two
percent (2%) of the
 
                                      64
<PAGE>
 
employee's gross compensation, the matching contribution is required to be
equal to 100% of the employee's contribution; (2) with respect to the
employee's elective contribution in excess of 2% and not in excess of 6% of
gross compensation, the matching contribution is required to be equal to 25%
of such employee's contribution; and (3) with respect to the employee's
elective contribution in excess of six percent (6%) of gross compensation,
there shall be no matching contribution. The 401(k) Plan permits, but does not
require, discretionary contributions to the 401(k) Plan by Holdings' Eligible
employees are vested 100% in their own contributions. Contributions made by
Holdings vest in equal installments over five years.
 
  Employment Agreements. Mr. Krakoff and Mr. Alic entered into employment
agreements with Holdings dated as of July 1, 1996. Each agreement provides for
a four year term. Pursuant to the agreements, Mr. Krakoff and Mr. Alic are
entitled to annual base salaries of not less than $400,000 and $300,000,
respectively. Mr. Krakoff and Mr. Alic are entitled to annual bonuses based on
the Company's EBITDA for any year, up to a maximum bonus in any one year of
100% of base salary. The agreements provide for indemnification of the
executives to the extent permissible under Delaware law. Pursuant to Mr.
Krakoff's agreement, Holdings agreed to establish a stock option plan for
employees of the Company and to make additional options available for grant in
the event of additional equity capital contributions to Holdings (subject to a
maximum of $200 million of contributed equity capital). The agreements provide
for severance benefits equal to one year's base salary and benefits (and a pro
rated bonus) upon termination of employment by Holdings without "cause" or by
the executive for "good reason" (which includes a change of control). Mr.
Krakoff and Mr. Alic also entered into noncompetition and confidentiality
agreements with Holdings. The noncompete period is one year after termination
of employment unless employment is terminated by Holdings without cause or by
the executive for good reason, in which case the noncompetition period is six
months. During the noncompetition period, the executives may not hire any
Company employee or solicit any trade show or publishing business from a third
party which has a relationship or contract with the Company.

                              THE EXCHANGE OFFER
 
PURPOSES AND EFFECTS OF THE EXCHANGE OFFER
 
  The Original Notes were sold by the Company on April 30, 1998 (the "Issue
Date") to the Initial Purchasers pursuant to a Purchase Agreement dated as of
April 27, 1998 (the "Purchase Agreement"). As a condition to the sale of the
Original Notes, the Company and the Initial Purchasers entered into the
Registration Rights Agreement on the Issue Date. Pursuant to the Registration
Rights Agreement, the Company agreed that, unless the Exchange Offer is not
permitted by applicable law or Commission policy, it would (i) file with the
Commission a Registration Statement under the Securities Act with respect to
the Exchange Notes within 60 days after the Issue Date, (ii) use its
reasonable best efforts to cause such Registration Statement to become
effective under the Securities Act within 150 days after the Issue Date and
(iii) upon effectiveness of the Registration Statement, commence the Exchange
Offer, keep the Exchange Offer open for at least 30 days (or a longer period
if required by law) and deliver to the Exchange Agent Exchange Notes in the
same aggregate principal amount at maturity as the Original Notes that were
tendered by holders thereof pursuant to the Exchange Offer.
 
  Under existing Commission interpretations, the Exchange Notes would in
general be freely transferable after the Exchange Offer without further
registration under the Securities Act; provided, that in the case of broker-
dealers, a prospectus meeting the requirements of the Securities Act will be
delivered as required. The Company has agreed to make available a prospectus
meeting the requirements of the Securities Act to any broker-dealer for use in
connection with any resale of any such Exchange Notes acquired as described
below for such period of 90 days after the Expiration Date. A broker-dealer
that delivers such a prospectus to purchasers in connection with such resales
will be subject to certain of the civil liability provisions under the
Securities Act, and will be bound by the Registration Rights Agreement
(including certain indemnification rights and obligations). A copy of the
Registration Rights Agreement has been filed as an exhibit to the Registration
Statement of which this Prospectus is a part. The Registration Statement of
which this Prospectus is a part is intended to satisfy certain of the
Company's obligations under the Registration Rights Agreement and the Purchase
Agreement.
 
  The Company is generally not required to file any registration statement to
register any outstanding Original Notes. Holders of Original Notes who do not
tender their Original Notes or whose Original Notes are tendered but not
accepted will have to rely on exemptions to registration requirements under
the securities laws, including the Securities Act, if they wish to sell their
Original Notes.
 
  With respect to the Exchange Notes, based upon an interpretation by the
staff of the Commission set forth in certain no-action letters issued to third
parties, the Company believes that a holder (other than (i) a broker-dealer
who purchases such Exchange Notes directly from the Company to resell pursuant
to Rule 144A or any other available exemption under the Securities Act or (ii)
any such holder which is an "affiliate" of the Company within the meaning of
Rule 405 under the Securities Act) who exchanges Original Notes for Exchange
Notes in the ordinary course of business and who is not participating, does
not intend to participate, and has no arrangement with any person to
participate, in the distribution of the Exchange Notes, will be allowed to
resell the Exchange Notes to the public without further registration under the
Securities Act and without delivering to the purchasers of the Exchange Notes
a prospectus that satisfies the requirements of Section 10 of the Securities
Act. However, if any holder acquires the Exchange Notes in the Exchange Offer
for the purpose of distributing or participating in the distribution of the
Exchange Notes or is a broker-dealer, such holder cannot rely on the position
of the staff of the Commission enumerated in certain no-action letters issued
to third parties and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction,
unless an exemption from registration is
 
                                      68
<PAGE>
 
otherwise available. Each broker-dealer that receives Exchange Notes for its
own account in exchange for Original Notes, where such Original Notes were
acquired by such broker-dealer as a result of market-making activities or
other trading activities, may be a statutory underwriter and must acknowledge
that it will deliver a prospectus in connection with any resale of such
Exchange Notes. The prospectus may be the Prospectus for the Exchange Offer,
so long as it contains a plan of distribution with respect to such resale
transaction. 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.
 
  This Prospectus, as it may be amended or supplemented from time to time, may
be used by a broker-dealer in connection with resales of Exchange Notes
received in exchange for Original Notes where such Original Notes were
acquired by such broker-dealer as a result of market-making or other trading
activities. Pursuant to the Registration Rights Agreement, the Company has
agreed to make this Prospectus, as it may be amended or supplemented from time
to time, available to broker-dealers for use in connection with any resale for
a period of 180 days after the Expiration Date. See "Plan of Distribution."
 
TERMS OF THE EXCHANGE OFFER
 
  Upon the terms and subject to the conditions set forth in this Prospectus
and in the accompanying Letter of Transmittal, the Company will accept any and
all Original Notes validly tendered and not withdrawn prior to the Expiration
Date. The Company will issue $1,000 principal amount of Exchange Notes in
exchange for each $1,000 principal amount of outstanding Original Notes
surrendered pursuant to the Exchange Offer. Holders may tender some or all of
their Original Notes pursuant to the Exchange Offer; provided, however, that
Original Notes may be tendered only in integral multiples of $1,000. The
Exchange Offer is not conditioned upon any minimum aggregate principal amount
of Original Notes being tendered for exchange.
 
  The form and terms of the Exchange Notes are the same as the form and terms
of the Original Notes except that (i) the Exchange Notes will be registered
under the Securities Act and, therefore, will not bear legends restricting
their transfer and (ii) holders of the Exchange Notes will not be entitled to
the certain rights of holders of Original Notes under the Registration Rights
Agreement, which rights will terminate upon the consummation of the Exchange
Offer. The Exchange Notes will evidence the same debt as the Original Notes
(which they replace) and will be issued under, and be entitled to the benefits
of, the Indenture, which also authorized the issuance of the Original Notes,
such that all outstanding Notes will be treated as a single class of debt
securities under the Indenture.
 
  Interest on the Exchange Notes will accrue from the most recent date to
which interest has been paid on the Original Notes or, if no interest has been
paid, from November 1, 1998. Accordingly, registered holders of Exchange Notes
on the relevant record date for the first interest payment date following the
consummation of the Exchange Offer will receive interest accruing from the
most recent date to which interest has been paid or, if no interest has been
paid, from November 1, 1998. Original Notes accepted for exchange will cease
to accrue interest from and after the date of the consummation of the Exchange
Offer. Holders whose Original Notes are accepted for exchange will not receive
any payment in respect of interest on such Original Notes otherwise payable on
any interest payment date, the record date for which occurs on or after
consummation of the Exchange Offer.
 
  As of the date of this Prospectus, $150 million aggregate principal amount
of the Original Notes are outstanding. Only a registered holder of the
Original Notes (or such holder's legal representative or attorney-in-fact) as
reflected on the records of the Trustee under the Indenture may participate in
the Exchange Offer. There will be no fixed record date for determining
registered holders of the Original Notes entitled to participate in the
Exchange Offer.
 
  Holders of the Original Notes do not have any appraisal or dissenters'
rights under the Indenture in connection with the Exchange Offer. The Company
intends to conduct the Exchange Offer in
 
                                      69
<PAGE>
 
accordance with the provisions of the Registration Rights Agreement and the
applicable requirements of the Securities Act, the Exchange Act and the rules
and regulations of the Commission thereunder. The Company shall be deemed to
have accepted validly tendered Original Notes when, as and if the Company has
given oral or written notice thereof to the Exchange Agent. The Exchange Agent
will act as agent for the tendering holders of Original Notes for the purposes
of receiving the Exchange Notes from the Company.
 
  If any tendered Original Notes are not accepted for exchange because of an
invalid tender, or due to the occurrence of certain other events set forth
herein or otherwise, certificates for any such unaccepted Original Notes will
be returned without expense to the tendering holders thereof (or in the case
of Original Notes tendered by book-entry transfer, such Original Notes will be
credited to the account of such holder maintained at the Depository), as
promptly as practicable after the expiration or termination of the Exchange
Offer.
 
  Holders who tender Original 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 Notes
pursuant to the Exchange Offer. The Company will pay all charges and expenses,
other than certain applicable taxes described below, in connection with the
Exchange Offer. See "The Exchange Offer--Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; TERMINATION
 
  The term "Expiration Date" shall mean 5:00 p.m., New York City time on
             unless the Company, in its sole discretion, extends the Exchange
Offer, in which case the term "Expiration Date" shall mean the latest date and
time to which the Exchange Offer is extended. In order to extend the Exchange
Offer the Company will notify the Exchange Agent of any extension by oral
(promptly confirmed in writing) or written notice and will make a public
announcement thereof, each prior to 9:00 a.m., New York City time, on the next
business day after the previously scheduled expiration date of the Exchange
Offer. Without limiting the manner in which the Company may choose to make a
public announcement of any delay, extension, amendment or termination of the
Exchange Offer, the Company shall have no obligation to publish, advertise or
otherwise communicate any such public announcement, other than by making a
timely release to an appropriate news agency.
 
  The Company reserves the right, in its sole discretion, (i) to delay
accepting any Original Notes, (ii) to extend the Exchange Offer, (iii) if any
conditions set forth below under "--Certain Conditions to the Exchange Offer"
shall not have been satisfied, to terminate the Exchange Offer by giving oral
or written notice of such delay, extension or termination to the Exchange
Agent or (iv) to amend the terms of the Exchange Offer in any manner. Any such
delay in acceptance, extension, termination or amendment will be followed as
promptly as practicable by oral or written notice thereof to the registered
holders. If the Exchange Offer is amended in a manner determined by the
Company to constitute a material change, the Company will promptly disclose
such amendment by means of a prospectus supplement that will be distributed to
the registered holders of Original Notes, and the Company will extend the
Exchange Offer for a period of five to ten business days, depending upon the
significance of the amendment and the manner of disclosure to such registered
holders, if the Exchange Offer would otherwise expire during such five to ten
business day period. The rights reserved by the Company in this paragraph are
in addition to the Company's rights set forth below under the caption "--
Certain Conditions of the Exchange Offer."
 
  If the Company extends the period of time during which the Exchange Offer is
open, or if it is delayed in accepting for exchange of, or in issuing and
exchanging the Exchange Notes for, any Original Notes, or is unable to accept
for exchange of, or issue Exchange Notes for, any Original Notes pursuant to
the Exchange Offer for any reason, then, without prejudice to the Company's
rights under the Exchange Offer, the Exchange Agent may, on behalf of the
Company, retain all Original Notes
 
                                      70
<PAGE>
 
tendered, and such Original Notes may not be withdrawn except as otherwise
provided below in "--Withdrawal of Tenders." The adoption by the Company of
the right to delay acceptance for exchange of, or the issuance and the
exchange of the Exchange Notes, for any Original Notes is subject to
applicable law, including Rule 14e-1(c) under the Exchange Act, which requires
that the Company pay the consideration offered or return the Original Notes
deposited by or on behalf of the holders thereof promptly after the
termination or withdrawal of the Exchange Offer.
 
PROCEDURES FOR TENDERING
 
  Only a registered holder of Original Notes may tender such Original Notes in
the Exchange Offer. To tender in the Exchange Offer, a holder must complete,
sign and date the Letter of Transmittal and any other documents referenced
therein, or facsimile thereof, have the signature thereon guaranteed if
required by the Letter of Transmittal and mail or otherwise deliver such
Letter of Transmittal or such facsimile to the Exchange Agent at the address
set forth below under "-- Exchange Agent" for receipt prior to the Expiration
Date. In addition, either (i) certificates for such Notes must be received by
the Exchange Agent along with the Letter of Transmittal, or (ii) a timely
confirmation of a book-entry transfer of such Notes, if such procedure is
available, into the Exchange Agent's account at the Depository Trust Company
("DTC" or the "Depository") pursuant to the procedure for book-entry transfer
described below, must be received by the Exchange Agent prior to the
Expiration Date, or (iii) the holder must comply with the guaranteed delivery
procedures described below.
 
  Any financial institution that is a participant in the Depository's Book-
Entry Transfer Facility system may make book-entry delivery of the Original
Notes by causing the Depository to transfer such Original Notes into the
Exchange Agent's account in accordance with the Depository's procedure for
such transfer. Although delivery of Original Notes may be effected through
book-entry transfer into the Exchange Agent's account at the Depository, the
Letter of Transmittal (or facsimile thereof), with any required signature
guarantees and any other required documents, must, in any case, be transmitted
to and received or confirmed by the Exchange Agent at its addresses set forth
under "--Exchange Agent" below prior to 5:00 p.m., New York City time, on the
Expiration Date. DELIVERY OF DOCUMENTS TO THE DEPOSITORY IN ACCORDANCE WITH
ITS PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT. The tender
by a holder which is not withdrawn prior to the Expiration Date will
constitute a binding agreement between such holder and the Company in
accordance with the terms and subject to the conditions set forth herein and
in the Letter of Transmittal.
 
  THE METHOD OF DELIVERY OF NOTES AND THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE
HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN
OVERNIGHT OR HAND DELIVERY SERVICE, PROPERLY INSURED. IF DELIVERY IS BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE
DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO LETTER OF
TRANSMITTAL OR NOTES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY REQUEST THEIR
RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO
EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS.
 
  Any beneficial owner of the Original Notes whose Original 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 such registered holder to tender on such beneficial
owner's behalf. If such beneficial owner wishes to tender on such owner's own
behalf, such owner must, prior to completing and executing the Letter of
Transmittal and delivering such owner's Original
 
                                      71
<PAGE>
 
Notes, either make appropriate arrangements to register ownership of the Notes
in such owner's name (to the extent permitted by the Indenture) or obtain a
properly completed assignment from the registered holder. The transfer of
registered ownership may take considerable time.
 
  If the Letter of Transmittal is signed by a person other than the registered
holder of any Original Notes (which term includes any participants in DTC
whose name appears on a security position listing as the owner of the Original
Notes) or if delivery of the Exchange Notes is to be made to a person other
than the registered holder, such Original Notes must be endorsed or
accompanied by a properly completed bond power, in either case signed by such
registered holder as such registered holder's name appears on such Original
Notes with the signature on the Original Notes or the bond power guaranteed by
an Eligible Institution (as defined below).
 
  Signatures on a Letter of Transmittal or a notice of withdrawal described
below (see "--Withdrawal of Tenders"), as the case may be, must be guaranteed
by an Eligible Institution unless the Original Notes tendered pursuant thereto
are tendered (i) by a registered holder who has not completed the box entitled
"Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution. In the event that signatures on a Letter
of Transmittal or a notice of withdrawal, as the case may be, are required to
be guaranteed, such guarantee must be made 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 Guarantor
Institution" within the meaning of Rule 17Ad-15 under the Exchange Act (any of
the foregoing, an "Eligible Institution").
 
  If the Letter of Transmittal or any Original Notes or assignments are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity,
such persons should so indicate when signing, and unless waived by the
Company, evidence satisfactory to the Company of their authority to so act
must be submitted with the Letter of Transmittal.
 
  The Exchange Agent and the Depository have confirmed that any financial
institution that is a participant in the Depository's system may utilize the
Depository's Automated Tender Offer Program to tender Original Notes.
 
  All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Original Notes will be
determined by the Company in its sole discretion, which determination will be
final and binding. The Company reserves the absolute right to reject any and
all Original Notes not properly tendered or any Original Notes, the Company's
acceptance of which would, in the opinion of counsel for the Company, be
unlawful. The Company also reserves the right to waive any defects,
irregularities or conditions of tender as to particular Notes. The Company's
interpretation of the terms and conditions of the Exchange Offer (including
the instructions in the Letter of Transmittal) will be final and binding on
all parties. Unless waived, any defects or irregularities in connection with
tenders of Original Notes must be cured within such time as the Company shall
determine. Although the Company intends to request the Exchange Agent to
notify holders of defects or irregularities with respect to tenders of
Original Notes, neither the Company, the Exchange Agent nor any other person
shall incur any liability for failure to give such notification. Tenders of
Original Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived.
 
  While the Company has no present plan to acquire any Original Notes which
are not tendered in the Exchange Offer or to file a registration statement to
permit resales of any Original Notes which are not tendered pursuant to the
Exchange Offer, the Company reserves the right in its sole discretion to
purchase or make offers for any Original Notes that remain outstanding
subsequent to the Expiration Date or, as set forth below under "--Certain
Conditions to the Exchange Offer," to terminate the
 
                                      72
<PAGE>
 
Exchange Offer and, to the extent permitted by applicable law, purchase
Original Notes in the open market, in privately negotiated transactions or
otherwise. The terms of any such purchases or offers could differ from the
terms of the Exchange Offer.
 
  By tendering, each holder will represent to the Company that, among other
things, (i) the Exchange Notes to be acquired by the holder of the Original
Notes in connection with the Exchange Offer are being acquired by the holder
in the ordinary course of business of the holder, (ii) the holder has no
arrangement or understanding with any person to participate in the
distribution of Exchange Notes, (iii) the holder acknowledges and agrees that
any person who is a broker-dealer registered under the Exchange Act or is
participating in the Exchange Offer for the purpose of distributing the
Exchange Notes must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction of the Exchange Notes acquired by such person and cannot rely on
the position of the staff of the Commission set forth in certain no-action
letters, (iv) the holder understands that a secondary resale transaction
described in clause (iii) above and any resales of Exchange Notes obtained by
such holder in exchange for Original Notes acquired by such holder directly
from the Company should be covered by an effective registration statement
containing the selling securityholder information required by Item 507 or Item
508, as applicable, of Regulation S-K of the Commission, and (v) the holder is
not an "affiliate," as defined in Rule 405 of the Securities Act, of the
Company. If the holder is a broker-dealer that will receive Exchange Notes for
its own account in exchange for Original Notes that were acquired as a result
of market-making activities or other trading activities, the holder is
required to acknowledge in the Letter of Transmittal that it will deliver a
prospectus in connection with any resale of such Exchange Notes; however, by
so acknowledging and by delivering a prospectus, the holder will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.
See "Plan of Distribution."
 
RETURN OF NOTES
 
  If any tendered Original Notes are not accepted for any reason set forth in
the terms and conditions of the Exchange Offer or if Original Notes are
withdrawn or are submitted for a greater principal amount than the holders
desire to exchange, such unaccepted, withdrawn or non-exchanged Original Notes
will be returned without expense to the tendering holder thereof (or, in the
case of Original Notes tendered by book-entry transfer into the Exchange
Agent's account at the Depository pursuant to the book-entry transfer
procedures described below, such Original Notes will be credited to an account
maintained with the Depository) as promptly as practicable upon termination of
the Exchange Offer.
 
BOOK-ENTRY TRANSFER
 
  The Exchange Agent will make a request to establish an account with respect
to the Original Notes at the Depository for purposes of the Exchange Offer
within two business days after the date of this Prospectus, and any financial
institution that is a participant in the Depository's system may make book-
entry delivery of Original Notes by causing the Depository to transfer such
Original Notes into the Exchange Agent's account at the Depository in
accordance with the Depository's procedures for transfer. However, although
delivery of Original Notes may be effected through book-entry transfer at the
Depository, the Letter of Transmittal or facsimile thereof, with any required
signature guarantees and any other required documents, must, in any case, be
transmitted to and received by the Exchange Agent at the address set forth
below under "--Exchange Agent" on or prior to the Expiration Date or pursuant
to the guaranteed delivery procedures described below.
 
GUARANTEED DELIVERY PROCEDURES
 
  Holders who wish to tender their Original Notes and (i) whose Original Notes
are not immediately available or (ii) who cannot deliver their Original Notes
(or complete the procedures for book-entry
 
                                      73
<PAGE>
 
transfer), the Letter of Transmittal or any other required documents to the
Exchange Agent prior to the Expiration Date, may effect a tender if: (a) the
tender is made through an Eligible Institution; (b) prior to the Expiration
Date, the Exchange Agent receives from such Eligible Institution a properly
completed and duly executed Notice of Guaranteed Delivery substantially in the
form provided by the Company (by facsimile transmission, mail or hand
delivery) setting forth the name and address of the holder, the certificate
number(s) of such Original Notes (if available) and the principal amount of
Original Notes tendered, stating that the tender is being made thereby and
guaranteeing that, within five New York Stock Exchange trading days after the
Expiration Date, the Letter of Transmittal (or a facsimile thereof) together
with the certificate(s) representing the Original Notes in proper form for
transfer (or a confirmation of a book-entry transfer into the Exchange Agent's
account at the Depository of Original Notes delivered electronically), and any
other documents required by the Letter of Transmittal will be deposited by the
Eligible Institution with the Exchange Agent; and (c) such properly executed
Letter of Transmittal (or facsimile thereof), as well as the certificate(s)
representing all tendered Original Notes in proper form for transfer (or a
confirmation of a book-entry transfer into the Exchange Agent's account at the
Depository of Original Notes delivered electronically), and all other
documents required by the Letter of Transmittal are received by the Exchange
Agent within five 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 Original Notes according to the
guaranteed delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
  Except as otherwise provided herein, tenders of Original Notes may be
withdrawn at any time prior to the Expiration Date. To withdraw a tender of
Original Notes in the Exchange Offer, a written or facsimile transmission
notice of withdrawal must be received by the Exchange Agent at its address set
forth herein prior to the Expiration Date. Any such notice of withdrawal must
(i) specify the name of the person having deposited the Original Notes to be
withdrawn (the "Depositor") and the name of the record holder of the Original
Notes to be withdrawn, if different than the Depositor, (ii) identify the
Original Notes to be withdrawn (including the certificate number or numbers
(if applicable) and principal amount of such Original Notes), and (iii) be
signed by the holder in the same manner as the original signature on the
Letter of Transmittal by which such Original Notes were tendered (including
any required signature guarantees). If Original Notes have been tendered
pursuant to the procedures for book-entry transfer, the notice of withdrawal
must specify the name and number of the account at DTC to be credited with the
withdrawal of the Original Notes. All questions as to the validity, form and
eligibility (including time of receipt) of such notices will be determined by
the Company in its sole discretion, whose determination shall be final and
binding on all parties. Any Original Notes so withdrawn will be deemed not to
have been validly tendered for purposes of the Exchange Offer and no Exchange
Notes will be issued with respect thereto unless the Original Notes so
withdrawn are validly retendered. Properly withdrawn Notes may be retendered
by following one of the procedures described above under "--Procedures for
Tendering" at any time prior to the Expiration Date.
 
CERTAIN CONDITIONS TO THE EXCHANGE OFFER
 
  Notwithstanding any other term of the Exchange Offer, the Company shall not
be required to accept for exchange, or exchange the Exchange Notes for, any
Original Notes not theretofore accepted for exchange, and may terminate or
amend the Exchange Offer as provided herein before the acceptance of such
Original Notes, if any of the following conditions exist: (a) any action or
proceeding is instituted or threatened in any court or by or before any
governmental agency with respect to the Exchange Offer which, in the
reasonable judgment of the Company, might impair the ability of the Company to
proceed with the Exchange Offer or have a material adverse effect on the
contemplated benefits of the Exchange Offer to the Company or there shall have
occurred any material adverse development in any existing action or proceeding
with respect to the Company or any of its
 
                                      74
<PAGE>
 
subsidiaries; or (b) there shall have been any material change, or development
involving a prospective change, in the business or financial affairs of the
Company or any of its subsidiaries which, in the reasonable judgment of the
Company, could reasonably be expected to materially impair the ability of the
Company to proceed with the Exchange Offer or materially impair the
contemplated benefits of the Exchange Offer to the Company; or (c) there shall
have been proposed, adopted or enacted any law, statute, rule or regulation
which, in the judgment of the Company, could reasonably be expected to
materially impair the ability of the Company to proceed with the Exchange
Offer or materially impair the contemplated benefits of the Exchange Offer to
the Company; or (d) any governmental approval which the Company shall, in its
reasonable discretion, deem necessary for the consummation of the Exchange
Offer as contemplated hereby shall have not been obtained. If the Company
determines in its reasonable discretion that any of these conditions are not
satisfied, the Company may (i) refuse to accept any Original Notes and return
all tendered Original Notes to the tendering holders, (ii) extend the Exchange
Offer and retain all Original Notes tendered prior to the expiration of the
Exchange Offer, subject, however, to the rights of holders to withdraw such
Original Notes (see "The Exchange Offer--Withdrawal of Tenders") or (iii)
waive such unsatisfied conditions with respect to the Exchange Offer and
accept all properly tendered Original Notes which have not been withdrawn. If
such waiver constitutes a material change to the Exchange Offer, the Company
will promptly disclose such waiver by means of a prospectus supplement that
will be distributed to the registered holders of the Original Notes, and the
Company will extend the Exchange Offer for a period of five to ten business
days, depending upon the significance of the waiver and the manner of
disclosure to the registered holders, if the Exchange Offer would otherwise
expire during such five to ten business day period.
 
  Holders may have certain rights and remedies against the Company under the
Registration Rights Agreement should the Company fail to consummate the
Exchange Offer, notwithstanding a failure of the conditions stated above. Such
conditions are not intended to modify those rights or remedies in any respect.
The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company regardless of the circumstances giving rise to such
condition or may be waived by the Company in whole or in part at any time and
from time to time in the Company's reasonable discretion. The failure by the
Company at any time to exercise the foregoing rights shall not be deemed a
waiver of any such right and each such right shall be deemed an ongoing right
which may be asserted at any time and from time to time.
 
TERMINATION OF CERTAIN RIGHTS
 
  All rights under Registration Rights Agreement (including registration
rights) of holders of the Original Notes eligible to participate in this
Exchange Offer will terminate upon consummation of the Exchange Offer except
with respect to the Company's continuing obligations (i) to indemnify the
holders (including any broker-dealers) and certain parties related to the
holders against certain liabilities (including liabilities under the
Securities Act), (ii) to provide, upon the request of any holder of a
transfer-restricted Original Note, the information required by Rule 144A(d)(4)
under the Securities Act in order to permit resales of such Original Notes
pursuant to Rule 144A, (iii) to use its best efforts to keep the Registration
Statement effective to the extent necessary to ensure that it is available for
resales of transfer-restricted Notes by broker-dealers for a period of 180
days from the date on which the Registration Statement is declared effective
and (iv) to provide copies of the latest version of the Prospectus to broker-
dealers upon their request for a period of 180 days from the date on which the
Registration Statement is declared effective. Insofar as indemnification for
liabilities arising under the Securities Act may be permitted pursuant to the
foregoing provisions, the Company has been informed that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.
 
EXCHANGE AGENT
 
  United States Trust Company of New York has been appointed as Exchange Agent
for the Exchange Offer. All questions and requests for assistance as well as
all correspondence in connection
 
                                      75
<PAGE>
 
with the Exchange Offer and the Letter of Transmittal should be addressed to
the Exchange Agent, as follows:
 
  By Facsimile (eligible institutions only):
 
    (212) 571-3080
 
  By Overnight Courier or by Hand:
 
    The Bank of New York
    101 Barclay Street
    Corporate Trust Services Window
    Ground Level
    New York, NY 10286
    Attn: Reorganization Section
 
  By Mail:
 
    The Bank of New York

    Attention: Reorganization Section
 
  To confirm by telephone, or for information, call the Exchange Agent at
(212) 805-6333. Requests for additional copies of this Prospectus, the Letter
of Transmittal or the Notice of Guaranteed Delivery should be directed to the
Exchange Agent.
 
FEES AND EXPENSES
 
  The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, telephone or in person by officers and regular
employees of the Company and its affiliates. The Company has not retained any
dealer-manager or other soliciting agent in connection with the Exchange Offer
and will not make any payments to brokers, dealers or others soliciting
acceptance of the Exchange Offer. The Company, however, will pay the Exchange
Agent reasonable and customary fees for its services and will reimburse it for
its reasonable out-of-pocket expenses in connection therewith. The cash
expenses to be incurred in connection with the Exchange Offer will be paid by
the Company and are estimated in the aggregate to be approximately $250,000.
Such expenses include fees and expenses of the Exchange Agent and Trustee,
accounting and legal fees and printing costs, among others.
 
  The Company will pay all transfer taxes, if any, applicable to the exchange
of Original Notes pursuant to the Exchange Offer. If, however, certificates
representing Exchange Notes, or Original Notes for principal amounts not
tendered or acceptable for exchange, are to be delivered to, or are to be
issued in the name of, any person other than the registered holders of the
Original Notes tendered, or if tendered Original Notes are registered in the
name of any person other than the person signing the Letter of Transmittal, or
if a transfer tax is imposed for any reason other than the exchange of
Original Notes pursuant to the Exchange Offer, then the amount of any such
transfer taxes (whether imposed on the registered holder or any other persons)
will be payable by the tendering holder. If satisfactory evidence of payment
of such taxes or exemption therefrom is not submitted with the Letter of
Transmittal, the amount of such transfer taxes will be billed directly to such
tendering holder of Original Notes.
 
ACCOUNTING TREATMENT
 
  The Exchange Notes will be recorded at the same carrying value as the
Original Notes as reflected in the Company's accounting records on the date of
the exchange. Accordingly, no gain or loss for accounting purposes will be
recognized. The expenses of the Exchange Offer will be amortized over the term
of the Exchange Notes.
 
                                      76
<PAGE>
 
CONSEQUENCE OF FAILURE TO EXCHANGE
 
  Participation in the Exchange Offer is voluntary. Holders of the Original
Notes are urged to consult their financial and tax advisors in making their
own decisions on what action to take. The Original Notes which are not
exchanged for the Exchange Notes pursuant to the Exchange Offer will remain
restricted securities. Accordingly, such Original Notes may be resold only (i)
to a person whom the seller reasonably believes is a qualified institutional
buyer (as defined in Rule 144A under the Securities Act) in a transaction
meeting the requirements of Rule 144A, (ii) in a transaction meeting the
requirements of Rule 144 under the Securities Act, (iii) outside the United
States to a foreign person in a transaction meeting the requirements of Rule
904 under the Securities Act, (iv) in accordance with another exemption from
the registration requirements of the Securities Act (and based upon an opinion
of counsel if the Company so requests), (v) to the Company or (vi) pursuant to
an effective registration statement and, in each case, in accordance with any
applicable securities laws of any state of the United States or any other
applicable jurisdiction.

                    DESCRIPTION OF AMENDED CREDIT FACILITY
 
  The summary of the Amended Credit Facility set forth below does not purport
to be complete and is qualified in its entirety by reference to all the
provisions of the credit agreement and related documents governing the Amended
Credit Facility, copies of which are filed as an exhibit to the Registration
Statement of which this Prospectus is a part.
 
  The Amended Credit Facility will consist of three components: a 5 1/2-year
term loan facility in an aggregate principal amount equal to $85 million (the
"Tranche A Term Loan Facility"), a 7-year term loan facility in an aggregate
principal amount equal to $125 million (the "Tranche B Term Loan Facility");
and a 5 1/2-year revolving credit facility in the maximum amount of $60
million (the "Revolving Credit Facility"). Loans made under the Tranche A Term
Loan Facility ("Tranche A Term Loans") and the Tranche B Term Loan Facility
("Tranche B Term Loans") are sometimes collectively referred to herein as
"Term Loans." Advances under the Revolving Credit Facility are sometimes
referred to herein as "Revolving Loans."
 
  The obligations of the Company under the Amended Credit Facility and any
related interest rate protection agreements will be guaranteed by Holdings and
by substantially all of the domestic subsidiaries of the Company (including,
without limitation, MAGIC). The Company's obligations in connection with the
Amended Credit Facility and the obligations of the guarantors will be secured
by liens on substantially all of their respective tangible and intangible
assets, including, but not limited to, mortgages on unencumbered real
property, blanket security interests in personal property and pledges of the
capital stock of the Company and substantially all of the Company's
subsidiaries (including, without limitation, MAGIC).
 
  The Term Loans were drawn in full on the closing date of the MAGIC
Acquisition to finance a portion of the MAGIC Acquisition, to replace or
refinance indebtedness under the Original Credit Facility, to pay related fees
and expenses and for general corporate purposes. Subject to compliance with
customary conditions precedent, the Revolving Credit Facility (which will
include sublimits for the issuances of letters of credit) will be available to
be drawn from time to time by the Company for working capital and general
corporate purposes (including permitted acquisitions).
 
  The Term Loans will be amortized in quarterly installments totalling
approximately $1.5 million in 1998, $7.0 million in 1999, $13.5 million in
2000, $17.0 million in 2001, $19.5 million in 2002, $31.5 million in 2003,
$60.25 million in 2004 and $59.75 in 2005. Principal amounts outstanding under
the Revolving Credit Facility will be due and payable in full at maturity,
approximately 5 1/2 years after the closing date of the Amended Credit
Facility.
 
  Interest on outstanding borrowings will accrue, at the option of the
Company, at the customary Alternate Base Rate (the "ABR") of The Chase
Manhattan Bank ("Chase") or at a reserve adjusted Eurodollar Rate (the
"Eurodollar Rate") plus, in each case, the Applicable Margin (as hereinafter
defined). The term "Applicable Margin" means a percentage that will vary in
accordance with a pricing matrix based upon operating performance targets and
step-downs to be agreed upon. The maximum Applicable Margin for Revolving
Loans and Tranche A Term Loans will equal 1.25% for loans based on ABR ("ABR
Loans") and 2.25% for loans based on the Eurodollar Rate ("Eurodollar Loans");
and for Tranche B Term Loans, 1.50% in the case of ABR Loans and 2.50% in the
case of Eurodollar Loans.
 
  In addition to paying interest on outstanding principal under the Amended
Credit Facility, the Company will be required to pay a commitment fee to the
lenders under the Revolving Credit Facility in respect of the unutilized
commitments thereunder at a rate equal to a percentage that will vary in
accordance with a pricing matrix based upon operating performance targets and
step-downs set forth
 
                                      78
<PAGE>
 
in the pricing matrix. The maximum commitment fee rate will be 0.50% per
annum. The Company will also pay letter of credit commissions on the
outstanding stated amount of all letters of credit issued
under the Revolving Credit Facility at a rate equal to the Applicable Margin
for Eurodollar Loans under the Revolving Credit Facility (subject to
adjustments based on the pricing matrix), plus a fronting fee to the bank
issuing such letters of credit at 0.25% per annum, and the customary
administrative, issuance, drawing, payment, negotiation and amendment charges
of the issuing bank.
 
  Subject in each case to certain exceptions, the following amounts are
required to be applied, as mandatory prepayments, to prepay the Term Loans:
(i) 50% of the net cash proceeds of certain issuances of equity by Holdings or
its subsidiaries; (ii) 100% of the net cash proceeds of the incurrence of
certain indebtedness by Holdings (or any successor corporation) or any of its
subsidiaries; (iii) 100% of the net cash proceeds of any sale or other
disposition by the Company or any of its subsidiaries of any assets (excluding
sales in the ordinary course of business, and subject to a limited exception
for reinvestment of such proceeds within 270 days); and (iv) 50% of excess
cash flow for each fiscal year. Mandatory prepayments will be applied pro rata
to the unpaid installments of the Tranche A Term Loans and the Tranche B Term
Loans, provided, that as long as any Tranche A Term Loans remain outstanding,
each holder of a Tranche B Term Loan will have the right to refuse any such
mandatory prepayment otherwise allocable to it, in which case the amount so
refused will be applied as an additional prepayment of the Tranche A Term
Loans. The Company will also have the right to optionally prepay the loans
under the Amended Credit Facility, without premium, in whole or in part.
Amounts applied as prepayments of the Revolving Credit Facility may be
reborrowed; amounts prepaid in respect of the Term Loans may not.
 
  Subject to customary exceptions, covenants include (but will not necessarily
be limited to) restrictions on fundamental changes; liens; indebtedness;
investments; dividend payments; lines of business; transactions with
affiliates; use of proceeds; certain matters respecting ownership of
subsidiaries; negative pledge clauses and clauses restricting subsidiary
distributions; modifications of certain documents (including the Indenture);

cross-default; bankruptcy events; certain ERISA events; material judgments;
material environmental claims; actual or asserted invalidity of any guarantee,
security interest or subordination provisions; and a change of control.

                             DESCRIPTION OF NOTES
 
GENERAL
 
  The Exchange Notes are to be issued under an Indenture, to be dated as of
April 30, 1998 (the "Indenture"), among the Company, the Guarantors and The
Bank of New York, as Trustee (the "Trustee"), a copy of which is filed as an
exhibit to the Registration Statement of which this Prospectus is a part. The
Indenture also governs the Original Notes. For purposes of the following
description, the Exchange Notes and Original Notes are at times collectively
referred to as the "Notes." The Exchange Notes and any Original Notes that
remain outstanding after consummation of the Exchange Offer will be treated as
a single class of securities under the Indenture.
 
  The Indenture is limited in aggregate principal amount to $250.0 million, of
which $150.0 million aggregate principal amount was issued in the Offering.
Additional notes may be issued in one or more series from time to time,
subject to the limitations set forth under "Certain Covenants--Limitation on
Indebtedness," which may vote as a class with the Notes. The following summary
of certain provisions of the Indenture and the Notes does not purport to be
complete and is subject to, and is qualified in its entirety by reference to,
all the provisions of the Indenture (including the definitions of certain
terms therein and those terms made a part thereof by the Trust Indenture Act
of 1939, as amended) and the Notes.
 
  The Notes will be unsecured, senior subordinated obligations of the Company,
limited to $150.0 million aggregate principal amount, and will mature on May
1, 2008. Each Note will bear interest at the rate per annum shown on the front
cover of this Prospectus from the date of issuance, or from the most recent
date to which interest has been paid or provided for, payable semi-annually on
May 1 and November 1 of each year commencing on November 1, 1998 to holders of
record at the close of business on the April 15 or October 15 immediately
preceding the interest payment date.
 
  Interest will be computed on the basis of a 360 day year comprised of twelve
30 day months. Principal of, premium, if any, and interest on the Notes will
be payable, and the Notes may be exchanged or transferred, at the office or
agency of the Company in the Borough of Manhattan, The City of New York (which
initially will be the corporate trust office of the Trustee in New York, New
York), except that, at the option of the Company, payment of interest may be
made by check mailed to the address of the holders as such address appears in
the Note Register. No service charge will be made for any registration of
transfer or exchange of Notes, but the Company may require payment of a sum
sufficient to cover any transfer tax or other similar governmental charge
payable in connection therewith.
 
  The Notes will be issued in fully registered form without interest coupons,
in denominations of $1,000 and any integral multiple of $1,000. The Notes will
be represented by one or more registered notes in global form and in certain
circumstances may be represented by Notes in definitive form. See "Book-Entry;
Delivery and Form."

OPTIONAL REDEMPTION
 
  Except as set forth below, the Notes will not be redeemable at the option of
the Company prior to May 1, 2003. On and after such date, the Notes will be
redeemable, at the Company's option, in whole or in part, at any time upon not
less than 30 nor more than 60 days prior notice mailed by first-class mail to
each holder's registered address, at the following redemption prices
(expressed in percentages of principal amount), plus accrued and unpaid
interest to the redemption date (subject to the right of holders of record on
the relevant record date to receive interest due on the relevant interest
payment date):
 
  If redeemed during the 12-month period commencing on May 1 of the years set
forth below:

         2006 and thereafter.........................  100.000%
</TABLE>
 
  In addition, at any time and from time to time prior to May 1, 2001, the
Company may redeem in the aggregate up to 35% of the original principal amount
of the Notes with the proceeds of one or more Equity Offerings received by, or
invested in, the Company so long as there is a Public Market at the time of
such redemption, at a redemption price (expressed as a percentage of principal
amount) of 109.250% plus accrued and unpaid interest, if any, to the
redemption date (subject to the right of holders of record on the relevant
record date to receive interest due on the relevant interest payment date);
provided, however, that at least 65% of the original principal amount of the
Notes must remain outstanding after each such redemption; provided further,
that each such redemption occurs within 90 days of the date of closing of such
Equity Offering.
 
  At any time on or prior to May 1, 2003, the Notes may also be redeemed as a
whole at the option of the Company upon the occurrence of a Change of Control,
upon not less than 30 nor more than 60 days prior notice (but in no event more
than 30 days after the occurrence of such Change of Control) mailed by first-
class mail to each holder's registered address, at a redemption price equal to
100% of the principal amount thereof plus the Applicable Premium as of, and
accrued and unpaid interest, if any, to, the date of redemption (the
"Redemption Date") (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date).
 
  "Applicable Premium" means, with respect to a Note at any Redemption Date,
the greater of (i) 1.0% of the principal amount of such Note and (ii) the
excess of (A) the present value at such time of (1) the redemption price of
such Note at May 1, 2003 (such redemption price being described under
"Optional Redemption") plus (2) all required interest payments due on such
Note through May 1, 2003, computed using a discount rate equal to the Treasury
Rate plus 50 basis points, over (B) the principal amount of such Note.
 
  "Treasury Rate" means the yield to maturity at the time of computation of
United States Treasury securities with a constant maturity (as compiled 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
Redemption Date (or, if such Statistical Release is no longer published, any
publicly available source of similar market data)) most nearly equal to the
period from the Redemption Date to May 1, 2003; provided, however, that if the
period from the Redemption Date to May 1, 2003 is not equal to the constant
maturity of a United States Treasury security for which a weekly average yield
is given, the Treasury Rate shall 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 such yields are given,
except that if the period from the Redemption Date to May 1, 2003 is less than
one year, the weekly average yield on actually traded United States Treasury
securities adjusted to a constant maturity of one year shall be used.
 
                                      81
<PAGE>
 
  In the case of any partial redemption, selection of the Notes for redemption
will be made by the Trustee on a pro rata basis, by lot or by such other
method as the Trustee in its sole discretion will deem to be fair and
appropriate, although no Note of $1,000 in original principal amount or less
will be redeemed in part. If any Note is to be redeemed in part only, the
notice of redemption relating to such Note will state the portion of the
principal amount thereof to be redeemed. A new Note in principal amount equal
to the unredeemed portion thereof will be issued in the name of the holder
thereof upon cancellation of the original Note.
 
RANKING AND SUBORDINATION
 
  The payment of the principal of, premium, if any, and interest on the Notes
is subordinated in right of payment, as set forth in the Indenture, to the
prior payment in full in cash or Cash Equivalents when due of all Senior
Indebtedness of the Company. However, payment from the money or the proceeds
of U.S. Government Obligations held in any defeasance trust described under
"Defeasance" below is not subordinate to any Senior Indebtedness or subject to
the restrictions described herein. As of December 31, 1997, after giving
effect to the Pro Forma Adjustments, the outstanding Senior Indebtedness of
the Company would have been $210.0 million (exclusive of unused commitments).
Although the Indenture contains limitations on the amount of additional
Indebtedness that the Company may Incur, under certain circumstances the
amount of such Indebtedness could be substantial and, in any case, such
Indebtedness may be Senior Indebtedness. See "Certain Covenants--Limitation on
Indebtedness" below.
 
  "Senior Indebtedness" is defined, whether outstanding on the Issue Date or
thereafter issued, created, Incurred or assumed, as the Bank Indebtedness and
all other Indebtedness of the Company, including accrued and unpaid interest
thereon (including interest accruing on or after the filing of any petition in
bankruptcy or for reorganization relating to the Company at the rate specified
in the documentation with respect thereto whether or not a claim for post
filing interest is allowed in such proceeding) and fees relating thereto,
unless, in the instrument creating or evidencing the same or pursuant to which
the same is outstanding, it is provided that the obligations in respect of
such Indebtedness are not superior in right of, or are subordinate to, payment
to the Notes; provided, however, that Senior Indebtedness will not include (i)
any obligation of the Company to any Subsidiary, (ii) any liability for
Federal, state, foreign, local or other taxes owed or owing by the Company,
(iii) any accounts payable or other liability to trade creditors arising in
the ordinary course of business (including Guarantees thereof or instruments
evidencing such liabilities), (iv) any Indebtedness, Guarantee or obligation
of the Company that is expressly subordinate or junior in right of payment to
any other Indebtedness, Guarantee or obligation of the Company, including any
Senior Subordinated Indebtedness and any Subordinated Obligations or (v) any
Capital Stock.
 
  Only Indebtedness of the Company that is Senior Indebtedness will rank
senior to the Notes in accordance with the provisions of the Indenture. The
Notes will in all respects rank pari passu with all other Senior Subordinated
Indebtedness of the Company. The Company has agreed in the Indenture that it
will not Incur, directly or indirectly, any Indebtedness that is subordinate
or junior in ranking in any respect to Senior Indebtedness unless such
Indebtedness is Senior Subordinated Indebtedness or is expressly subordinated
in right of payment to Senior Subordinated Indebtedness. In addition, a
Subsidiary Guarantor may not Incur any Indebtedness if such Indebtedness is
subordinate or junior in ranking in any respect to any Guarantor Senior
Indebtedness of such Subsidiary Guarantor unless such Indebtedness is
Guarantor Senior Subordinated Indebtedness of such Subsidiary Guarantor or is
expressly subordinated in right of payment to Guarantor Senior Subordinated
Indebtedness of such Subsidiary Guarantor. Unsecured Indebtedness is not
deemed to be subordinate or junior to secured indebtedness merely because it
is unsecured.
 
  The Company may not pay principal of, premium, if any, or interest on, the
Notes or make any deposit pursuant to the provisions described under
"Defeasance" below and may not otherwise
 
                                      82
<PAGE>
 
purchase, redeem or retire any Notes (collectively, "pay the Notes") if (i)
any Senior Indebtedness is not paid when due in cash or Cash Equivalents or
(ii) any other default on Senior Indebtedness occurs and the maturity of such
Senior Indebtedness is accelerated in accordance with its terms unless, in
either case, the default has been cured or waived and any such acceleration
has been rescinded or such Senior Indebtedness has been paid in full in cash
or Cash Equivalents. However, the Company may pay the Notes without regard to
the foregoing if the Company and the Trustee receive written notice approving
such payment from the Representative of the Senior Indebtedness with respect
to which either of the events set forth in clause (i) or (ii) of the
immediately preceding sentence has occurred and is continuing. During the
continuance of any default (other than a default described in clause (i) or
(ii) of the second preceding sentence) with respect to any Designated Senior
Indebtedness pursuant to which the maturity thereof may be accelerated
immediately without further notice (except such notice as may be required to
effect such acceleration) or the expiration of any applicable grace periods,
the Company may not pay the Notes for a period (a "Payment Blockage Period")
commencing upon the receipt by the Trustee (with a copy to the Company) of
written notice (a "Blockage Notice") of such default from the Representative
of the holders of such Designated Senior Indebtedness specifying an election
to effect a Payment Blockage Period and ending 179 days thereafter (or earlier
if such Payment Blockage Period is terminated (i) by written notice to the
Trustee and the Company from the Person or Persons who gave such Blockage
Notice, (ii) because the default giving rise to such Blockage Notice is no
longer continuing or (iii) because such Designated Senior Indebtedness has
been repaid in full). Notwithstanding the provisions described in the
immediately preceding sentence, unless the holders of such Designated Senior
Indebtedness or the Representative of such holders have accelerated the
maturity of such Designated Senior Indebtedness, the Company may resume
payments on the Notes after the end of such Payment Blockage Period. Not more
than one Blockage Notice may be given in any consecutive 360-day period,
irrespective of the number of defaults with respect to Designated Senior
Indebtedness during such period.
 
  Upon any payment or distribution of the assets or securities of the Company
upon a total or partial liquidation, dissolution, reorganization or bankruptcy
of or similar proceeding relating to the Company or its property, the holders
of Senior Indebtedness will be entitled to receive payment in full in cash or
Cash Equivalents of the Senior Indebtedness (including interest accruing
after, or which would accrue but for, the commencement of any proceeding at
the rate specified in the applicable Senior Indebtedness, whether or not a
claim for such interest would be allowed) before the holders of the Notes are
entitled to receive any payment or distribution, and until the Senior
Indebtedness is paid in full in cash or Cash Equivalents, any payment or
distribution to which holders of the Notes would be entitled but for the
subordination provisions of the Indenture will be made to holders of the
Senior Indebtedness as their interests may appear. If a payment or
distribution is made to holders of the Notes that, due to the subordination
provisions, should not have been made to them, such holders are required to
hold it in trust for the holders of Senior Indebtedness and pay it over to
them as their interests may appear.
 
  If payment of the Notes is accelerated because of an Event of Default, the
Company or the Trustee will promptly notify the holders of the Designated
Senior Indebtedness or the Representative of such holders of the acceleration.
The Company may not pay the Notes until five Business Days after such holders
or the Representative of the Designated Senior Indebtedness receive notice of
such acceleration and, thereafter, may pay the Notes only if the subordination
provisions of the Indenture otherwise permit payment at that time.
 
  By reason of such subordination provisions contained in the Indenture, in
the event of insolvency, creditors of the Company who are holders of Senior
Indebtedness may recover more, ratably, than the Noteholders.
 
                                      83

GUARANTEES
 
  Holdings and each Subsidiary Guarantor will unconditionally guarantee,
jointly and severally, to each holder and the Trustee, on a senior
subordinated basis, the full and prompt payment of principal of, premium, if
any, and interest on the Notes, and of all other obligations under the
Indenture.
 
  The Indebtedness evidenced by each Note Guarantee (including the payment of
principal of, premium, if any, and interest on the Notes) will be subordinated
to all Guarantor Senior Indebtedness of such Guarantor on the same basis as
the Notes are subordinated to Senior Indebtedness of the Company. As of
December 31, 1997, after giving effect to the Pro Forma Adjustments, there
would have been approximately $210.0 million of Guarantor Senior Indebtedness
(all of which would have represented Guarantees of borrowings under the Senior
Credit Agreement). Although the Indenture contains limitations on the amount
of additional Indebtedness that the Company's Restricted Subsidiaries may
Incur, under certain circumstances the amount of such Indebtedness could be
substantial and, in any case, such Indebtedness may be Guarantor Senior
Indebtedness. See "Certain Covenants--Limitation on Indebtedness" below. See
"--Ranking and Subordination" above.
 
  The obligations of each Guarantor will be limited to the maximum amount as
will, after giving effect to all other contingent and fixed liabilities of
such Guarantor (including, without limitation, any Guarantees under the Senior
Credit Agreement) and after giving effect to any collections from or payments
made by or on behalf of any other Guarantor in respect of the obligations of
such other Guarantor under its Note Guarantee or pursuant to its contribution
obligations under the Indenture, result in the obligations of such Guarantor
under its Note Guarantee not constituting a fraudulent conveyance or
fraudulent transfer under federal or state law.
 
  Each Subsidiary Guarantor may consolidate with or merge into or sell its
assets to the Company or another Wholly-Owned Subsidiary Guarantor without
limitation. Each Subsidiary Guarantor may consolidate with or merge into or
sell all or substantially all its assets to a corporation, partnership, trust,
limited partnership, limited liability company or other similar entity other
than the Company or a Wholly-Owned Subsidiary Guarantor (whether or not
affiliated with the Subsidiary Guarantor) except that if the surviving
corporation of any such merger or consolidation is a Subsidiary of the
Company, such Subsidiary shall not be a Foreign Subsidiary. Upon the sale or
disposition of a Subsidiary Guarantor (by merger, consolidation, the sale of
its Capital Stock or the sale of all or substantially all of its assets) to a
Person (whether or not an Affiliate of the Subsidiary Guarantor) which is not
a Subsidiary of the Company, which sale or disposition is otherwise in
compliance with the Indenture (including the covenant described under "Certain
Covenants--Limitation on Sales of Assets and Subsidiary Stock"), such
Subsidiary Guarantor will be deemed released from all its obligations under
the Indenture and its Subsidiary Guarantee and such Subsidiary Guarantee will
terminate; provided, however, that any such termination will occur only to the
extent that all obligations of such Subsidiary Guarantor under the Senior
Credit Agreement and all of its Guarantees of, and under all of its pledges of
assets or other security interests which secure, any other Indebtedness of the
Company will also terminate upon such release, sale or transfer.
 
CHANGE OF CONTROL
 
  Upon the occurrence of any of the following events (each a "Change of
Control"), unless the Company shall have exercised its right to redeem the
Notes as described under "--Optional Redemption", each holder will have the
right to require the Company to repurchase all or any part of such holder's
Notes at a purchase price in cash equal to 101% of the principal amount
thereof plus accrued and unpaid interest, if any, to the date of purchase
(subject to the right of holders of record on the relevant record date to
receive interest due on the relevant interest payment date):
 
    (i) (A) any "person" (as such term is used in Sections 13(d) and 14(d) of
  the Exchange Act), other than one or more Permitted Holders, is or becomes
  the beneficial owner (as defined in Rules
 
                                      84
<PAGE>
 
  13d-3 and 13d-5 under the Exchange Act, except that such person shall be
  deemed to have "beneficial ownership" of all shares that any such person
  has the right to acquire, whether such right is exercisable immediately or
  only after the passage of time), directly or indirectly, of more than 35%
  (or, if there is a Public Market at the time such person is or is deemed to
  have beneficial ownership, more than 50%) of the total voting power of the
  Voting Stock of the Company or Holdings (or its successor by merger,
  consolidation or other business combination) (for the purposes of this
  clause, such person shall be deemed to beneficially own any Voting Stock of
  the Company or Holdings held by a parent corporation, if such person
  "beneficially owns" (as defined above), directly or indirectly, more than
  35% of the voting power of the Voting Stock of such parent corporation);
  and (B) if there is no Public Market, the Permitted Holders "beneficially
  own" (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly
  or indirectly, in the aggregate a lesser percentage of the total voting
  power of the Voting Stock of the Company or Holdings (or its successor by
  merger, consolidation or purchase of all or substantially all of its
  assets) than such other person and do not have the right or ability by
  voting power, contract or otherwise to elect or designate for election a
  majority of the board of directors of the Company or such successor (for
  the purposes of this clause, such other person shall be deemed to
  beneficially own any Voting Stock of a specified corporation held by a
  parent corporation, if such other person "beneficially owns" (as defined in
  clause (A) above), directly or indirectly, more than 35% of the voting
  power of the Voting Stock of such parent corporation and the Permitted
  Holders "beneficially own" (as defined in this clause (B)), directly or
  indirectly, in the aggregate a lesser percentage of the voting power of the
  Voting Stock of such parent corporation and do not have the right or
  ability by voting power, contract or otherwise to elect or designate for
  election a majority of the board of directors of such parent corporation);
  or
 
    (ii) during any period of two consecutive years, individuals who at the
  beginning of such period constituted the Board of Directors of the Company
  or Holdings (together with any new directors whose election by such Board
  of Directors or whose nomination for election by the shareholders of the
  Company or Holdings, as the case may be, was approved by a vote of at least
  a majority of the directors of the Company or Holdings then still in office
  who were either directors at the beginning of such period or whose election
  or nomination for election was previously so approved or is a designee of
  the Permitted Holders or was nominated or elected by such Permitted Holders
  or any of their designees) cease for any reason to constitute a majority of
  the Board of Directors of the Company or Holdings then in office; or
 
    (iii) the sale, lease, transfer, conveyance or other disposition (other
  than by way of merger or consolidation), in one or a series of related
  transactions, of all or substantially all of the assets of the Company and
  its Restricted Subsidiaries taken as a whole to any "person" (as such term
  is used in Sections 13(d) and 14(d) of the Exchange Act) other than a
  Permitted Holder; or
 
    (iv) the adoption by the stockholders of a plan for the liquidation or
  dissolution of the Company.
 
  Within 30 days following any Change of Control, unless the Company has
mailed a redemption notice with respect to all the outstanding Notes in
connection with such Change of Control as described under "--Optional
Redemption", the Company will mail a notice to each holder with a copy to the
Trustee stating: (i) that a Change of Control has occurred and that such
holder has the right to require the Company to purchase such holder's Notes at
a purchase price in cash equal to 101% of the principal amount thereof plus
accrued and unpaid interest, if any, to the date of purchase (subject to the
right of holders of record on a record date to receive interest on the
relevant interest payment date); (ii) the repurchase date (which shall be no
earlier than 30 days nor later than 60 days from the date such notice is
mailed); and (iii) the procedures determined by the Company, consistent with
the Indenture, that a holder must follow in order to have its Notes purchased.
 
  The Company will comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations
in connection with the repurchase of Notes
 
                                      85
<PAGE>
 
pursuant to this covenant. To the extent that the provisions of any securities
laws or regulations conflict with provisions of the Indenture, the Company
will comply with the applicable securities laws and regulations and will not
be deemed to have breached its obligations described in the Indenture by
virtue thereof.
 
  The occurrence of certain of the events that would constitute a Change of
Control would constitute a default under the Senior Credit Agreement. Future
Senior Indebtedness of Holdings, the Company and its Subsidiaries may also
contain prohibitions of certain events that would constitute a Change of
Control or require such Senior Indebtedness to be repurchased upon a Change of
Control. Moreover, the exercise by the holders of their right to require the
Company to repurchase the Notes could cause a default under such Senior
Indebtedness, even if the Change of Control itself does not, due to the
financial effect of such repurchase on the Company. Finally, the Company's
ability to pay cash to the holders upon a repurchase may be limited by the
Company's then existing financial resources. There can be no assurance that
sufficient funds will be available when necessary to make any required
repurchases. Even if sufficient funds were otherwise available, the terms of
the Senior Credit Agreement will (and other Senior Indebtedness may) prohibit
the Company's prepayment of Notes prior to their scheduled maturity.
Consequently, if the Company is not able to prepay the Bank Indebtedness and
any other Senior Indebtedness containing similar restrictions or obtain
requisite consents, as described above, the Company will be unable to fulfill
its repurchase obligations if holders of Notes exercise their repurchase
rights following a Change of Control, thereby resulting in a default under the
Indenture.
 
  The Change of Control provisions described above may deter certain mergers,
tender offers and other takeover attempts involving the Company by increasing
the capital required to effectuate such transactions. The definition of
"Change of Control" includes a disposition of all or substantially all of the
property and assets of the Company and its Restricted Subsidiaries. With
respect to the disposition of property or assets, the phrase "all or
substantially all" as used in the Indenture varies according to the facts and
circumstances of the subject transaction, has no clearly established meaning
under New York law (which is the choice of law under the Indenture) and is
subject to judicial interpretation. Accordingly, in certain circumstances
there may be a degree of uncertainty in ascertaining whether a particular
transaction would involve a disposition of "all or substantially all" of the
property or assets of a Person, and therefore it may be unclear as to whether
a Change of Control has occurred and whether the Company is required to make
an offer to repurchase the Notes as described above.
 
CERTAIN COVENANTS
 
  The Indenture contains certain covenants including, among others, the
following:
 
  Limitation on Indebtedness. (a) The Company will not, and will not permit
any of its Restricted Subsidiaries to, Incur any Indebtedness; provided,
however, that the Company and its Restricted Subsidiaries which are Subsidiary
Guarantors may Incur Indebtedness if on the date thereof, after giving pro
forma effect to the incurrence of such Indebtedness, the Leverage Ratio for
the Company and its Restricted Subsidiaries is less than (i) 6.50 to 1.00, if
such Indebtedness is Incurred on or prior to the second anniversary of the
Issue Date, and (ii) 6.00 to 1.00, if such Indebtedness is Incurred
thereafter.
 
  (b) Notwithstanding the foregoing paragraph (a), the Company and its
Restricted Subsidiaries may Incur the following Indebtedness: (i) Indebtedness
Incurred pursuant to the Senior Credit Agreement of (x) up to $210.0 million
in term loan borrowings outstanding at any time and (y) up to $60.0 million in
revolving credit borrowings outstanding at any time; (ii) the Subsidiary
Guarantees and Guarantees of Indebtedness Incurred pursuant to paragraph (a)
or clause (i) of this paragraph (b); (iii) Indebtedness of the Company owing
to and held by any Wholly-Owned Subsidiary or Indebtedness of a Restricted
Subsidiary owing to and held by the Company or any Wholly-Owned Subsidiary;
provided,
 
                                      86
<PAGE>
 
however, that any subsequent issuance or transfer of any Capital Stock or any
other event which results in any such Wholly-Owned Subsidiary ceasing to be a
Wholly-Owned Subsidiary or any subsequent transfer of any such Indebtedness
(except to the Company or a Wholly-Owned Subsidiary) will be deemed, in each
case, to constitute the Incurrence of such Indebtedness by the issuer thereof;
(iv) Indebtedness represented by (x) $150.0 million aggregate principal amount
of the Notes, (y) any Indebtedness (other than the Indebtedness described in

Refinancing Indebtedness Incurred in respect of any Indebtedness described in
this clause (iv) or clause (v) or Incurred pursuant to paragraph (a) above;
(v) Indebtedness of a Restricted Subsidiary Incurred and outstanding on the
date on which such Restricted Subsidiary was acquired by the Company;
provided, however, that at the time such Restricted Subsidiary is acquired by

Indebtedness pursuant to paragraph (a) above after giving effect to the
Incurrence of such Indebtedness pursuant to this clause (v); (vi) Indebtedness
under Currency Agreements and Interest Rate Agreements; provided, however,
that in the case of Currency Agreements and Interest Rate Agreements, such

fide hedging purposes of the Company or its Restricted Subsidiaries (as
determined in good faith by the Board of Directors or senior management of the
Company) and correspond in terms of notional amount, duration, currencies and
interest rates, as applicable, to Indebtedness of the Company or its
Restricted Subsidiaries Incurred without violation of the Indenture or to
business transactions of the Company or its Restricted Subsidiaries on
customary terms entered into in the ordinary course of business; and (vii)
Indebtedness (other than Indebtedness described in clauses (i)-(vi)) in a
principal amount which, when taken together with the principal amount of all
other Indebtedness Incurred pursuant to this clause (vii) and then
outstanding, will not exceed $20.0 million.
 
  (c) Neither the Company nor any Restricted Subsidiary will Incur any
Indebtedness under paragraph (b) above if the proceeds thereof are used,
directly or indirectly, to refinance any Subordinated Obligations of the
Company unless such Indebtedness will be subordinated to the Notes to at least
the same extent as such Subordinated Obligations. No Subsidiary Guarantor will
Incur any Indebtedness under paragraph (b) above if the proceeds thereof are
used, directly or indirectly, to refinance any Guarantor Subordinated
Obligations of such Subsidiary Guarantor unless such Indebtedness will be
subordinated to the obligations of such Subsidiary Guarantor under its
Subsidiary Guarantee to at least the same extent as such Guarantor
Subordinated Obligations.
 
  (d) For purposes of determining compliance with, and the outstanding
principal amount of any particular Indebtedness Incurred pursuant to and in
compliance with, this covenant, in the event that Indebtedness meets the
criteria of more than one of the types of Indebtedness described in paragraph
(b) above, the Company, in its sole discretion, will classify such item of
Indebtedness and only be required to include the amount and type of such

Indebtedness is subordinate or junior in ranking in any respect to any Senior
Indebtedness unless such Indebtedness is Senior Subordinated Indebtedness or
is contractually subordinated in right of payment to Senior Subordinated
Indebtedness. No Subsidiary Guarantor will Incur any Indebtedness if such
Indebtedness is contractually subordinate or junior in ranking in any respect
to any Guarantor Senior Indebtedness of such Subsidiary Guarantor unless such
Indebtedness is Guarantor Senior Subordinated Indebtedness of such Subsidiary
Guarantor or is contractually subordinated in right of payment to Guarantor
Senior Subordinated Indebtedness of such Subsidiary Guarantor.

final maturity, in each case due within one year of the date of purchase,
repurchase or acquisition) or (iv) make any Investment (other than a Permitted
Investment) in any Person (any such dividend, distribution, purchase,
redemption, repurchase, defeasance, other acquisition, retirement or
Investment being herein referred to in clauses (i) through (iv) as a

of Consolidated Interest Expense for such period; (B) the aggregate Net Cash
Proceeds received by the Company from the issue or sale of its Capital Stock

or (y) received from an issuance or sale of such Capital Stock to a Subsidiary
of the Company or an employee stock ownership plan or similar trust to the
extent such sale to an employee stock ownership plan or similar trust is
financed by loans from or guaranteed by the Company or any Restricted
Subsidiary unless such loans have been repaid with cash on or prior to the
date of determination); (C) the amount by which Indebtedness of the Company is

the Company (less the amount of any cash, or other property, distributed by
the Company upon such conversion or exchange); and (D) the amount equal to the
net reduction in Investments (other than Permitted Investments) made by the
Company or any of its Restricted Subsidiaries in any Person resulting from (i)
repurchases or redemptions of such Investments by such Person, proceeds
realized upon the sale of such Investment to an unaffiliated purchaser,
repayments of loans or advances or other transfers of assets as a return of

(valued in each case as provided in the definition of "Investment") not to
exceed, in the case of any Unrestricted Subsidiary, the amount of Investments
(excluding Permitted Investments) previously made by the Company or any
Restricted Subsidiary in such Unrestricted Subsidiary, which amount was
included in the calculation of the amount of Restricted Payments; provided,
however, that no amount will be included under this clause (D) to the extent
it is already included in Consolidated Net Income.
 
  (b) The provisions of paragraph (a) will not prohibit: (i) any purchase or
redemption of Capital Stock or Subordinated Obligations of the Company made by
exchange for, or out of the proceeds of
 
                                      88
<PAGE>
 
the substantially concurrent sale of, Capital Stock of the Company (other than
Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary
or an employee stock ownership plan or similar trust to the extent such sale
to an employee stock ownership plan or similar trust is financed by loans from
or guaranteed by the Company or any Restricted Subsidiary unless such loans
have been repaid with cash on or prior to the date of determination);

permitted under "Limitation on Sales of Assets and Subsidiary Stock" below;
provided, however, that such purchase or redemption will be excluded in
subsequent calculations of the amount of Restricted Payments; (iv) dividends
paid within 60 days after the date of declaration if at such date of
declaration such dividend would have complied with this provision; provided,
however, that such dividends will be included in subsequent calculations of
the amount of Restricted Payments; (v) cash dividends to Holdings for the
purpose of, and in amounts equal to, amounts required to permit Holdings (A)
to redeem or repurchase Capital Stock of Holdings (or pay dividends to AHI
Advanstar for the purpose of redeeming or repurchasing membership interests in

the repurchase provisions under employee stock option or stock purchase
agreements or other agreements to compensate management employees provided,
however, that such dividends will be included in subsequent calculations of
the amount of Restricted Payments; (B) to make loans or advances to employees
or directors of the Company or any Subsidiary the proceeds of which are used
to purchase Capital Stock of Holdings or membership interests in AHI Advanstar
LLC; provided, however, that such dividends will be included in subsequent
calculations of the amount of Restricted Payments; (C) to pay any Federal,
state or local income taxes to the extent that such income taxes are
attributable to the income of the Company and its Subsidiaries, pay franchise
taxes and other fees required to maintain its legal existence, corporate
overhead expenses Incurred in the ordinary course of business, and salaries or
other compensation of employees who perform services for both Holdings and the
Company; provided, however, that such dividends will be excluded in subsequent
calculations of the amount of Restricted Payments and (D) so long as no
Default or Event of Default shall have occurred and be continuing, in an
amount not to exceed $100,000 in any fiscal year to enable Holdings to make
payments to holders of its Capital Stock in lieu of the issuance of fractional
shares of its Capital Stock; provided, however, that such dividends will be
excluded in subsequent calculations of the amount of Restricted Payments;
provided further, however, that the aggregate amount of dividends paid to
Holdings pursuant to this clause (v) shall not exceed $3.0 million in any
fiscal year; and (vi) repurchases of Capital Stock deemed to occur upon the
exercise of stock options if such Capital Stock represents a portion of the

  Limitation on Liens. The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer to
exist any Lien (other than Permitted Liens and Liens securing Senior
Indebtedness and Guarantor Senior Indebtedness) upon any of its property or
assets (including Capital Stock), whether owned on the date of the Indenture
or thereafter acquired, securing any Indebtedness, unless contemporaneously
therewith effective provision is made to secure the Indebtedness due under the
Indenture and the Notes or, in respect of Liens on any Restricted Subsidiary's
property or assets, any Subsidiary Guarantee of such Restricted Subsidiary,
equally and ratably with (or prior to in the case of Liens with respect to
Subordinated Obligations) the Indebtedness secured by such Lien for so long as
such Indebtedness is so secured.

  Limitation on Restrictions on Distributions from Restricted
Subsidiaries. The Company will not, and will not permit any Restricted
Subsidiary to, create or otherwise cause or permit to exist or become
effective any consensual encumbrance or consensual restriction on the ability
of any Restricted Subsidiary to (i) pay dividends or make any other
distributions on its Capital Stock or pay any Indebtedness or other
obligations owed to the Company, (ii) make any loans or advances to the
Company or (iii) transfer any of its property or assets to the Company, except
(a) any encumbrance or restriction pursuant to an agreement in effect at or
entered into on the date of the Indenture (including, without limitation, the
Senior Credit Agreement); (b) any encumbrance or restriction with respect to a
Restricted Subsidiary pursuant to an agreement relating to any Indebtedness
Incurred by a Restricted Subsidiary on or prior to the date on which such
Restricted Subsidiary was acquired by the Company (other than Indebtedness
Incurred as consideration in, or to provide all or any portion of the funds
utilized to consummate, the transaction or series of related transactions
pursuant to which such Restricted Subsidiary became a Restricted Subsidiary or
was acquired by the Company) and outstanding on such date; (c) any encumbrance
or restriction with respect to a Restricted Subsidiary pursuant to an
agreement effecting a refinancing of Indebtedness Incurred pursuant to an
agreement referred to in clause (a) or (b) of this covenant or this clause (c)
or contained in any amendment to an agreement referred to in clause (a) or (b)
of this covenant or this clause (c); provided, however, that the encumbrances
and restrictions with respect to such Restricted Subsidiary contained in any
such agreement or amendment are no less favorable to the Holders of the Notes
than encumbrances and restrictions contained in such agreements; (d) in the
case of clause (iii) above, any encumbrance or restriction (A) that restricts
in a customary manner the subletting, assignment or transfer of any property
or asset that is subject to a lease, license or similar contract, or the
assignment or transfer of any such lease, license or other contract, (B) by
virtue of any transfer of, agreement to transfer, option or right with respect
to, or Lien on, any property or assets of the Company or any Restricted
Subsidiary not otherwise prohibited by the Indenture, (C) contained in
mortgages, pledges or other security agreements securing Indebtedness of a
Restricted Subsidiary to the extent such encumbrance or restrictions restrict
the transfer of the property subject to such mortgages, pledges or other
security agreements or (D) pursuant to customary provisions restricting
dispositions of real property interests set forth in any reciprocal easement
agreements of the Company or any Restricted Subsidiary; (e) any restriction
with respect to a Restricted Subsidiary (or any of its property or assets)
imposed pursuant to an agreement entered into for the direct or indirect sale
or disposition of all or substantially all the Capital Stock or assets of such
Restricted Subsidiary (or the property or assets that are subject to such
restriction) pending the closing of such sale or disposition; and (f)
encumbrances or restrictions arising or existing by reason of applicable law.
 
  Limitation on Sales of Assets and Subsidiary Stock. (a) The Company will
not, and will not permit any of its Restricted Subsidiaries to, make any Asset
Disposition unless (i) the Company or such Restricted Subsidiary receives
consideration at the time of such Asset Disposition at least equal to the fair
market value, as determined in good faith by the Board of Directors (including
as to the value of all non-cash consideration), of the shares and assets
subject to such Asset Disposition and (ii) at least 85% of the consideration
thereof received by the Company or such Restricted Subsidiary is in the form
of cash or Cash Equivalents.
 
  With respect to any Asset Disposition occurring on or after the Issue Date
from which the Company or any Restricted Subsidiary receives Net Available
Cash, the Company or such Restricted Subsidiary shall apply an amount equal to
100% of the Net Available Cash from such Asset Disposition at its election, to
either (i) prepay, repay or purchase Senior Indebtedness or Indebtedness
(other than any Preferred Stock) of a Wholly Owned Subsidiary (in each case
other than Indebtedness owed to the Company or an Affiliate of the Company)
within 365 days from the later of the date of such Asset Disposition or the
receipt of such Net Available Cash; (ii) invest in Additional Assets within
365 days from the later of the date of such Asset Disposition or the receipt
of such Net Available Cash; or (iii) make an offer pursuant to paragraph (b)
to purchase the Notes and other Senior Subordinated
 
                                      90
<PAGE>
 
Indebtedness outstanding with similar provisions requiring the Company to make
an offer to purchase such Indebtedness with the proceeds from any Asset
Disposition ("Pari Passu Notes") at 100% of the principal amount thereof (or
100% of the accreted value of such Pari Passu Notes so tendered if such Pari
Passu Notes were issued at a discount) plus accrued and unpaid interest, if
any, to the date of purchase; provided, however, that, in connection with any
prepayment, repayment or purchase of Indebtedness pursuant to clause (i)
above, the Company or such Restricted Subsidiary will retire such Indebtedness
and will cause the related loan commitment (if any), unless such commitment is
for the provision of a revolving credit facility, to be permanently reduced in
an amount equal to the principal amount so prepaid, repaid or purchased.
Notwithstanding the foregoing provisions, the Company and its Restricted
Subsidiaries will not be required to apply any Net Available Cash in
accordance herewith except to the extent that the aggregate Net Available Cash
from all Asset Dispositions which are not applied in accordance with this
covenant exceed $1.0 million. Any Net Available Cash from an Asset Disposition
that is not invested or applied as provided and within the time period set
forth in clauses (i) and (ii) of the first sentence of this paragraph will be
deemed to constitute "Excess Proceeds."
 
  For the purposes of this covenant and for no other purpose, the following
will be deemed to be cash: (x) the assumption by the transferee of Senior
Indebtedness of the Company or Indebtedness of any Restricted Subsidiary of
the Company and the release of the Company or such Restricted Subsidiary from
all liability on such Senior Indebtedness or Indebtedness in connection with
such Asset Disposition (in which case the Company will, without further
action, be deemed to have applied such assumed Indebtedness in accordance with
clause (i) of the preceding paragraph); (y) securities received by the Company
or any Restricted Subsidiary of the Company from the transferee that are
promptly converted by the Company or such Restricted Subsidiary into cash; and
(z) the fair market value, as determined by the Board of Directors of the
Company in good faith, of any Designated Noncash Consideration received by the
Company or any of its Restricted Subsidiaries in any Asset Disposition, taken
together with the fair market value, as determined by the Board of Directors
of the Company in good faith, of all other Designated Noncash Consideration
received pursuant to this clause (z) that is at that time outstanding, not to
exceed $25.0 million at the time of the receipt of such Designated Noncash
Consideration (with the fair market value of each item of Designated Noncash
Consideration being measured at the time received and without giving effect to
subsequent changes in value), in which case such Designated Noncash
Consideration shall not constitute Net Available Cash.
 
  (b) When the aggregate amount of Excess Proceeds exceeds $5.0 million (with
lesser amounts to be carried forward for purposes of determining whether an
Offer (as defined) is required with respect to the Excess Proceeds from any
subsequent Asset Disposition), the Company will be required to apply such
Excess Proceeds to the repayment of the Notes and any Pari Passu Notes as
follows: (A) the Company will make an offer to purchase (an "Offer") within
ten days of such time from all holders of the Notes in accordance with the
procedures set forth in the Indenture in the maximum principal amount
(expressed as a multiple of $1,000) of Notes that may be purchased out of an
amount (the "Note Amount") equal to the product of such Excess Proceeds
multiplied by a fraction, the numerator of which is the outstanding principal
amount of the Notes and the denominator of which is the sum of the outstanding
principal amount of the Notes and the outstanding principal amount (or
accreted value, as the case may be) of the Pari Passu Notes at a purchase
price of 100% of the principal amount thereof plus accrued and unpaid
interest, if any, to the date of purchase and (B) the Company will make an
offer to purchase any Pari Passu Notes (a "Pari Passu Offer") in an amount
equal to the excess of the Excess Proceeds over the Note Amount at a purchase
price of 100% of the principal amount (or accreted value, as the case may be)
thereof plus accrued and unpaid interest, if any, to the date of purchase in
accordance with the procedures (including prorating in the event of
oversubscription) set forth in the documentation governing such Pari Passu
Notes with respect to the Pari Passu Offer. If the aggregate purchase price of
the Notes and Pari Passu Notes tendered pursuant to the Offer and the Pari
Passu Offer is less than the Excess Proceeds, the remaining Excess Proceeds
will be available to the Company to fund other corporate purposes not
otherwise prohibited by the Indenture.
 
                                      91
<PAGE>
 
  (c) The Company will comply, to the extent applicable, with the requirements
of Section 14(e) of the Exchange Act and any other securities laws or
regulations in connection with the repurchase of Notes pursuant to the
Indenture. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, the Company will comply
with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under the Indenture by virtue thereof.
 
  Limitation on Asset Swaps. The Company will not, and will not permit any
Restricted Subsidiary to, engage in any Asset Swaps, unless: (i) at the time
of entering into such Asset Swap and immediately after giving effect to such
Asset Swap, no Default or Event of Default shall have occurred and be
continuing or would occur as a consequence thereof; (ii) in the event such
Asset Swap involves the transfer by the Company or any Restricted Subsidiary
of assets having an aggregate fair market value, as determined by the Board of
Directors of the Company in good faith, in excess of $1.0 million, the terms
of such Asset Swap have been approved by a majority of the members of the
Board of Directors of the Company and (iii) in the event such Asset Swap
involves an aggregate amount in excess of $10.0 million, the Company has
received a written opinion from an independent investment banking firm of
nationally recognized standing that such Asset Swap is fair to the Company or
such Restricted Subsidiary, as the case may be, from a financial point of
view.
 
  Limitation on Affiliate Transactions. (a) The Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, enter
into or conduct any transaction (including the purchase, sale, lease or
exchange of any property or the rendering of any service) with any Affiliate
of the Company (an "Affiliate Transaction") unless: (i) the terms of such
Affiliate Transaction are no less favorable to the Company or such Restricted
Subsidiary, as the case may be, than those that could be obtained at the time
of such transaction in arm's-length dealings with a Person who is not such an
Affiliate; (ii) in the event such Affiliate Transaction involves an aggregate
amount in excess of $1.0 million, the terms of such transaction have been
approved by a majority of the members of the Board of Directors of the Company
and by a majority of the members of such Board having no personal stake in
such transaction, if any (and such majority or majorities, as the case may be,
determines that such Affiliate Transaction satisfies the criteria in (i)
above); and (iii) in the event such Affiliate Transaction involves an
aggregate amount in excess of $5.0 million, the Company has received a written
opinion from an independent investment banking firm of nationally recognized
standing that such Affiliate Transaction is not materially less favorable than
those that might reasonably have been obtained in a comparable transaction at
such time on an arm's-length basis from a Person that is not an Affiliate;
provided, however, that this clause (iii) will not apply to any Affiliate
Transaction with any joint venture or similar entity in which the Permitted
Holders do not have any direct or indirect interests other than the interests
of the Company and its Restricted Subsidiaries in such joint venture or
similar entity.
 
  (b) The foregoing paragraph (a) will not apply to (i) any Restricted Payment
permitted to be made pursuant to the covenant described under "Limitation on
Restricted Payments," (ii) any issuance of (A) securities to any of the
Permitted Holders or (B) securities, or other payments, awards or grants in
cash, securities or otherwise pursuant to, or the funding of, employment
arrangements, stock options and stock ownership plans approved by the Board of
Directors of the Company, (iii) loans or advances to employees in the ordinary
course of business of the Company or any of its Restricted Subsidiaries or
(iv) any transaction between the Company and a Wholly-Owned Subsidiary or
between Wholly-Owned Subsidiaries.
 
  Limitation on Dispositions of Capital Stock of Restricted Subsidiaries. The
Company (i) will not, and will not permit any Restricted Subsidiary of the
Company to, transfer, convey, sell, lease or otherwise dispose of any Capital
Stock of any Restricted Subsidiary to any Person (other than the Company or a
Wholly Owned Subsidiary), unless (A) such transfer, conveyance, sale, lease or
other disposition is a sale of the common stock of such Restricted Subsidiary
and, after giving effect to the consummation thereof, the Company owns (x)
more than 50% of the outstanding common stock of
 
                                      92
<PAGE>
 
such Restricted Subsidiary or (y) none of the outstanding common stock of such
Restricted Subsidiary and (B) the cash net proceeds from such transfer,
conveyance, sale, lease or other disposition are applied in accordance with
the covenant described above under "Limitation on Sales of Assets and
Subsidiary Stock"; and (ii) will not permit any Restricted Subsidiary to issue
any of its Capital Stock (other than, if necessary, shares of its Capital
Stock constituting directors' qualifying shares) to any Person other than to
the Company or a Wholly-Owned Subsidiary, unless such issuance is an issuance
of the common stock of such Restricted Subsidiary and, after giving effect to
the consummation thereof, the Company owns (x) more than 50% of the
outstanding common stock of such Restricted Subsidiary or (y) none of the
outstanding common stock of such Restricted Subsidiary.
 
  SEC Reports. Notwithstanding that the Company may not be subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act, to the
extent permitted by the Exchange Act, the Company will file with the
Commission, and provide, within 15 days after the Company is required to file
the same with the Commission, the Trustee and the holders of the Notes with
the annual reports and the information, documents and other reports (or copies
of such portions of any of the foregoing as the Commission may by rules and
regulations prescribe) that are specified in Sections 13 and 15(d) of the
Exchange Act. In the event that the Company is not permitted to file such
reports, documents and information with the Commission pursuant to the
Exchange Act, the Company will nevertheless deliver such Exchange Act
information to the Trustee and the holders of the Notes as if the Company were
subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act.
 
  Merger and Consolidation. The Company will not consolidate with or merge
with or into, or convey, transfer or lease all or substantially all its assets
to, any Person, unless: (i) the resulting, surviving or transferee Person (the
"Successor Company") will be a corporation, partnership, trust, limited
liability company or other similar entity organized and existing under the
laws of the United States of America, any State thereof or the District of
Columbia and the Successor Company (if not the Company) will expressly assume,
by supplemental indenture, executed and delivered to the Trustee, in form
satisfactory to the Trustee, all the obligations of the Company under the
Notes and the Indenture; (ii) immediately after giving effect to such
transaction (and treating any Indebtedness that becomes an obligation of the
Successor Company or any Subsidiary of the Successor Company as a result of
such transaction as having been Incurred by the Successor Company or such
Subsidiary at the time of such transaction), no Default or Event of Default
shall have occurred and be continuing; (iii) immediately after giving effect
to such transaction, the Successor Company would be able to Incur at least an
additional $1.00 of Indebtedness pursuant to paragraph (a) of "Limitation on
Indebtedness"; and (iv) the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger or transfer and such supplemental indenture (if any) comply with the
Indenture.
 
  The Successor Company will succeed to, and be substituted for, and may
exercise every right and power of, the Company under the Indenture, but, in
the case of a lease of all or substantially all its assets, the Company will
not be released from the obligation to pay the principal of and interest on
the Notes.
 
  Notwithstanding the foregoing clauses (ii) and (iii), (i) any Restricted
Subsidiary of the Company may consolidate with, merge into or transfer all or
part of its properties and assets to the Company and (ii) the Company may
merge with an Affiliate incorporated solely for the purpose of reincorporating
the Company in another jurisdiction to realize tax or other benefits.

Guarantee pursuant to which such Subsidiary Guarantor will unconditionally
Guarantee, on a joint and several basis, the full and prompt payment of the
principal of, premium, if any and interest on the Notes on a senior

  Each of the following constitutes an Event of Default under the Indenture:
(i) a default in any payment of interest on any Note when due, continued for
30 days, whether or not such payment is prohibited by the provisions described
under "Ranking and Subordination" above, (ii) a default in the payment of
principal of any Note when due at its Stated Maturity, upon optional
redemption, upon required repurchase, upon declaration or otherwise, whether
or not such payment is prohibited by the provisions described under "Ranking
and Subordination" above, (iii) the failure by the Company to comply with its
obligations under "Certain Covenants--Merger and Consolidation" above, (iv)
failure by the Company to comply for 30 days after notice with any of its
obligations under the covenants described under "Change of Control" above or
under covenants described under "Certain Covenants" above (in each case, other
than a failure to purchase Notes which will constitute an Event of Default
under clause (ii) above), (v) the failure by the Company to comply for 60 days
after notice with its other agreements contained in the Indenture, (vi)
Indebtedness of the Company or any Restricted Subsidiary is not paid within
any applicable grace period after final maturity or is accelerated by the
holders thereof because of a default and the total amount of such Indebtedness
unpaid or accelerated exceeds $5.0 million (the "cross acceleration
provision"), (vii) certain events of bankruptcy, insolvency or reorganization
of the Company or a Significant Subsidiary (the "bankruptcy provisions"),
(viii) any judgment or decree for the payment of money in excess of $5.0
million is rendered against the Company or a Significant Subsidiary and such
judgment or decree remains undischarged or unstayed for a period of 60 days
after such judgment becomes final and non-appealable (the "judgment default
provision") or (ix) any Note Guarantee ceases to be in full force and effect
(except as contemplated by the terms of the Indenture) or any Guarantor denies
or disaffirms its obligations under the Indenture or its Note Guarantee.
However, a default under clauses (iv) and (v) will not constitute an Event of
Default until the Trustee or the holders of 25% in principal amount of the
outstanding Notes notify the Company of the default and the Company does not
cure such default within the time specified in clauses (iv) and (v) hereof
after receipt of such notice.
 
  If an Event of Default occurs and is continuing, the Trustee or the holders
of at least 25% in principal amount of the outstanding Notes by notice to the
Company and the Trustee may declare the principal of and accrued and unpaid
interest, if any, on all the Notes to be due and payable. Upon such a
declaration, such principal and accrued and unpaid interest will be due and
payable immediately. If an Event of Default relating to certain events of
bankruptcy, insolvency or reorganization of the Company occurs and is
continuing, the principal of and accrued and unpaid interest on all the Notes
will become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any holders. Under certain
circumstances, the holders of a majority in principal amount of the
outstanding Notes may rescind any such acceleration with respect to the Notes
and its consequences.
 
  Subject to the provisions of the Indenture relating to the duties of the
Trustee, if an Event of Default occurs and is continuing, the Trustee will be
under no obligation to exercise any of the rights or powers under the
Indenture at the request or direction of any of the holders unless such
holders have offered to the Trustee reasonable indemnity or security against
any loss, liability or expense. Except to enforce the right to receive payment
of principal, premium, if any, or interest when due, no holder may pursue any
remedy with respect to the Indenture or the Notes unless (i) such holder has
previously given the Trustee notice that an Event of Default is continuing,
(ii) holders of at least 25% in principal amount of the outstanding Notes have
requested the Trustee to pursue the remedy, (iii) such holders have offered
the Trustee reasonable security or indemnity against any loss, liability or
expense, (iv) the Trustee has not complied with such request within 60 days
after the receipt of the
 
                                      94
<PAGE>
 
request and the offer of security or indemnity and (v) the holders of a
majority in principal amount of the outstanding Notes have not given the
Trustee a direction that, in the opinion of the Trustee, is inconsistent with
such request within such 60-day period. Subject to certain restrictions, the
holders of a majority in principal amount of the outstanding Notes are given
the right to direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or of exercising any trust or power
conferred on the Trustee. The Trustee, however, may refuse to follow any
direction that conflicts with law or the Indenture or that the Trustee
determines is unduly prejudicial to the rights of any other holder or that
would involve the Trustee in personal liability. Prior to taking any action
under the Indenture, the Trustee will be entitled to indemnification
satisfactory to it in its sole discretion against all losses and expenses
caused by taking or not taking such action.
 
  The Indenture provides that if a Default occurs and is continuing and is
known to the Trustee, the Trustee must mail to each holder notice of the
Default within 90 days after it occurs. Except in the case of a Default in the
payment of principal of, premium, if any, or interest on any Note, the Trustee
may withhold notice if and so long as a committee of its Trust officers in
good faith determines that withholding notice is in the interests of the
Noteholders. In addition, the Company is required to deliver to the Trustee,
within 120 days after the end of each fiscal year, a certificate indicating
whether the signers thereof know of any Default that occurred during the
previous year. The Company also is required to deliver to the Trustee, within
30 days after the occurrence thereof, written notice of any events which would
constitute certain Defaults, their status and what action the Company is
taking or proposes to take in respect thereof.
 
AMENDMENTS AND WAIVERS
 
  Subject to certain exceptions, the Indenture may be amended with the consent
of the holders of a majority in principal amount of the Notes then outstanding
and any past default or compliance with any provisions may be waived with the
consent of the holders of a majority in principal amount of the Notes then
outstanding. However, without the consent of each holder of an outstanding
Note affected, no amendment may, among other things, (i) reduce the amount of
Notes whose holders must consent to an amendment, (ii) reduce the stated rate
of or extend the stated time for payment of interest on any Note, (iii) reduce
the principal of or extend the Stated Maturity of any Note, (iv) reduce the
premium payable upon the redemption or repurchase of any Note or change the
time at which any Note may be redeemed as described under "Optional
Redemption" above, (v) make any Note payable in money other than that stated
in the Note, (vi) impair the right of any holder to receive payment of
principal of and interest on such holder's Notes on or after the due dates
therefor or to institute suit for the enforcement of any payment on or with
respect to such holder's Notes or (vii) make any change in the amendment
provisions which require each holder's consent or in the waiver provisions.
 
  Without the consent of any holder, the Company, the Guarantors and the
Trustee may amend the Indenture to cure any ambiguity, omission, defect or
inconsistency, to provide for the assumption by a successor corporation,
partnership, trust or limited liability company of the obligations of the
Company under the Indenture, to provide for uncertificated Notes in addition
to or in place of certificated Notes (provided that the uncertificated Notes
are issued in registered form for purposes of Section 163(f) of the Code, or
in a manner such that the uncertificated Notes are described in Section 163(f)
(2) (B) of the Code), to add Guarantees with respect to the Notes, to secure
the Notes, to add to the covenants of the Company for the benefit of the
holders or to surrender any right or power conferred upon the Company, to make
any change that does not adversely affect the rights of any holder or to
comply with any requirement of the Commission in connection with the
qualification of the Indenture under the Trust Indenture Act. However, no
amendment may be made to the subordination provisions of the Indenture that
adversely affects the rights of any holder of Senior Indebtedness then
outstanding unless the holders of such Senior Indebtedness (or any group or
representative thereof authorized to give a consent) consent to such change.
 
                                      95
<PAGE>
 
  The consent of the holders is not necessary under the Indenture to approve
the particular form of any proposed amendment. It is sufficient if such
consent approves the substance of the proposed amendment. After an amendment
under the Indenture becomes effective, the Company is required to mail to the
holders a notice briefly describing such amendment. However, the failure to
give such notice to all the holders, or any defect therein, will not impair or
affect the validity of the amendment.
 
DEFEASANCE
 
  The Company at any time may terminate all its obligations under the Notes
and the Indenture ("legal defeasance"), except for certain obligations,
including those respecting the defeasance trust and obligations to register
the transfer or exchange of the Notes, to replace mutilated, destroyed, lost
or stolen Notes and to maintain a registrar and paying agent in respect of the
Notes, and after giving effect to such legal defeasance, any omission to
comply with such obligations shall no longer constitute a Default or Event of
Default with respect to the Notes. If the Company exercises its legal
defeasance option, the Note Guarantees in effect at such time will terminate.
The Company at any time may terminate its obligations under covenants
described under "Certain Covenants" (other than "Merger and Consolidation"),
the operation of the cross acceleration provision, the bankruptcy provisions
with respect to Significant Subsidiaries, the judgment default provision and
the Note Guarantee provision described under "Events of Default" above and the
limitations contained in clauses (iii) and (iv) under "Certain Covenants--
Merger and Consolidation" above ("covenant defeasance") and thereafter any
omission to comply with such obligations shall no longer constitute a Default
or Event of Default with respect to the Notes.
 
  The Company may exercise its legal defeasance option notwithstanding its
prior exercise of its covenant defeasance option. If the Company exercises its
legal defeasance option, payment of the Notes may not be accelerated because
of any event that, in the absence of such legal defeasance, would have
constituted an Event of Default with respect thereto. If the Company exercises
its covenant defeasance option, the events specified in clause (iv), (vi),
(vii) (with respect only to Significant Subsidiaries), (viii) or (ix) under
"Events of Default" above will no longer constitute an Event of Default, and
payment of the Notes may not be accelerated because of the occurrence of any
such event or because of the failure of the Company to comply with clause
(iii) or (iv) under "Certain Covenants--Merger and Consolidation" above.
 
  In order to exercise either defeasance option, the Company must irrevocably
deposit in trust (the "defeasance trust") with the Trustee money or U.S.
Government Obligations for the payment of principal, premium, if any, and
interest on the Notes to redemption or maturity, as the case may be, and must
comply with certain other conditions, including delivery to the Trustee of an
Opinion of Counsel to the effect that holders of the Notes will not recognize
income, gain or loss for Federal income tax purposes as a result of such
deposit and defeasance and will be subject to Federal income tax on the same
amount and in the same manner and at the same times as would have been the
case if such deposit and defeasance had not occurred (and, in the case of
legal defeasance only, such Opinion of Counsel must be based on a ruling of
the Internal Revenue Service or other change in applicable Federal income tax
law).

  The Bank of New York is the Trustee under the Indenture and has been

GOVERNING LAW
 
  The Indenture provides that it, the Notes and the Note Guarantees will be
governed by, and construed in accordance with, the laws of the State of New
York without giving effect to applicable principles of conflicts of law to the
extent that the application of the law of another jurisdiction would be
required thereby.

The Company will keep the Exchange Offer open for not less than 30 days (or
longer, if required by applicable law) after the date on which notice of the
Exchange Offer is mailed to the holders of the Original Notes.
 
  If (i) because of any change in law or applicable interpretations thereof by
the staff of the Commission, the Company is not permitted to effect the
Exchange Offer as contemplated hereby, (ii) any Securities validly tendered
pursuant to the Exchange Offer are not exchanged for Exchange Securities
within 185 days after the Issue Date, (iii) any Initial Purchaser so requests
with respect to Original Notes not eligible to be exchanged for Exchange Notes
in the Exchange Offer, (iv) any Holder so requests because any applicable law
or interpretations do not permit such holder of Original Notes to participate
in the Exchange Offer, (v) any holder of Notes so requests because such Holder
participated in the Exchange Offer and did not receive freely transferable
Exchange Notes in exchange for tendered Original Notes, or (vi) the Company so
elects, then the Company will file with the Commission a shelf registration
statement (the "Shelf Registration Statement") to cover resales of Transfer
Restricted Securities by such holders who satisfy certain conditions relating
to the provision of information in connection with the Shelf Registration
Statement. For purposes of the foregoing, "Transfer Restricted Securities"
means each Original Note until (i) the date on which such Note has been
exchanged for a freely transferable Exchange Note in the Exchange Offer; (ii)
the date on which such Original Note has been effectively registered under the
Securities Act and disposed of in accordance with the Shelf Registration
Statement or (iii) the date on which such Original Note is distributed to the
public pursuant to Rule 144 under the Securities Act or is salable pursuant to
Rule 144(k) under the Securities Act.
 
  The Company will use its reasonable best efforts to have the Exchange Offer
Registration Statement or, if applicable, the Shelf Registration Statement
(each, a "Registration Statement") declared effective by the Commission as
promptly as practicable after the filing thereof. Unless the Exchange Offer
would not be permitted by a policy of the Commission, the Company will
commence the Exchange Offer and will use its reasonable best efforts to
consummate the Exchange Offer as promptly as practicable, but in any event
prior to 185 days after the Issue Date. If applicable, the Company will use
its reasonable best efforts to keep the Shelf Registration Statement effective
for a period of two years after the Issue Date.
 
  Subject to certain conditions and limitations set forth in the Registration
Rights Agreement, if (i) the applicable Registration Statement is not filed
with the Commission on or prior to 60 days after the Issue Date; (ii) the
Exchange Offer Registration Statement or the Shelf Registration Statement, as
the case may be, is not declared effective within 150 days after the Issue
Date; (iii) the Exchange Offer is not consummated on or prior to 185 days
after the Issue Date or (iv) the Shelf Registration Statement is filed and
declared effective within 150 days after the Issue Date but shall thereafter
cease to be effective (at any time that the Company is obligated to maintain
the effectiveness thereof) without being
 
                                      109
<PAGE>
 
succeeded within 45 days by an additional Registration Statement filed and
declared effective (each such event referred to in clauses (i) through (iv), a
"Registration Default"), the Company will be obligated to pay liquidated
damages to each holder of Transfer Restricted Securities, during the period of
one or more such Registration Defaults, in an amount equal to $0.192 per week
per $1,000 principal amount of the Original Notes constituting Transfer
Restricted Securities held by such holder until the applicable Registration
Statement is filed, the Exchange Offer Registration Statement is declared
effective and the Exchange Offer is consummated or the Shelf Registration
Statement is declared effective or again becomes effective, as the case may
be. All accrued liquidated damages shall be paid to holders in the same manner
as interest payments on the Original Notes on semi-annual payment dates which
correspond to interest payment dates for the Original Notes. Following the
cure of all Registration Defaults, the accrual of liquidated damages will
cease. Notwithstanding the foregoing, the Company may issue a notice (a
"Suspension Notice") to the Holders stating that a Shelf Registration
Statement may not be used; a Suspension Notice may be given by the Company
pending the announcement of material information by the Company which the
Board of Directors of the Company has determined, based upon an opinion of
counsel, would be required to be disclosed in such Registration Statement in
order to make the statements therein not misleading, and may issue any
Suspension Notice suspending use of the Shelf Registration Statement required
under applicable securities laws to be issued (a "Suspension"). In the event
that the aggregate number of days in any consecutive twelve-month period for
which all such Suspension Notices are issued and effective exceeds 45 days in
the aggregate, then the Company will be obligated to pay liquidated damages to
each Holder of Transfer Restricted Securities, during the period of one or
more such Suspension, in an amount equal to $0.192 per week per $1,000
principal amount of Transfer Restricted Securities held by such Holder.
 
  The Exchange and Registration Rights Agreement also will provide that the
Company (i) shall make available for a period of 180 days after the
consummation of the Exchange Offer a prospectus meeting the requirements of
the Securities Act to any broker-dealer for use in connection with any resale
of any such Exchange Notes and (ii) shall pay all expenses incident to the
Exchange Offer (including the expense of one counsel to the holders of the
Notes) and will indemnify certain holders of the Original Notes (including any
broker-dealer) against certain liabilities, including liabilities under the
Securities Act. A broker-dealer which delivers such a prospectus to purchasers
in connection with such resales will be subject to certain of the civil
liability provisions under the Securities Act and will be bound by the
provisions of the Registration Rights Agreement (including certain
indemnification rights and obligations).
 
  Each holder of Original Notes who wishes to exchange such Notes for Exchange
Notes in the Exchange Offer will be required to make certain representations,
including representations that (i) any Exchange Notes to be received by it
will be acquired in the ordinary course of its business; (ii) it has no
arrangement or understanding with any person to participate in the
distribution of the Exchange Notes and (iii) it is not an "affiliate" (as
defined in Rule 405 under the Securities Act) of the Company, 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 holder is not a broker-dealer, it will be required to represent that
it is not engaged in, and does not intend to engage in, the distribution of
the Exchange Notes. If the holder is a broker-dealer that will receive
Exchange Notes for its own account in exchange for Original Notes that were
acquired as a result of market-making activities or other trading activities
(an "Exchanging Dealer"), it will be required to acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Notes.
 
  Holders of the Original Notes will be required to make certain
representations to the Company (as described above) in order to participate in
the Exchange Offer and will be required to deliver information to be used in
connection with the Shelf Registration Statement in order to have their
 
                                      110
<PAGE>
 
Original Notes included in the Shelf Registration Statement and benefit from
the provisions regarding liquidated damages set forth in the preceding
paragraphs. A holder who sells Original Notes pursuant to the Shelf
Registration Statement generally will be required to be named as a selling
securityholder 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 such sales and will be bound by the
provisions of the Registration Rights Agreement which are applicable to such a
holder (including certain indemnification obligations).
 
  For so long as the Original Notes are outstanding, the Company will continue
to provide to holders of the Original Notes and to prospective purchasers of
the Original Notes the information required by Rule 144A(d)(4) under the
Securities Act.
 
  Each Guarantor will agree to be bound by the terms and provisions of the
Registration Rights Agreement with respect to registration of the Note
Guarantees.
 
  The foregoing description of the Registration Rights Agreement is a summary
only, does not purport to be complete and is qualified in its entirety by
reference to all provisions of the Registration Rights Agreement. A copy of
the Registration Rights Agreement is filed as an exhibit to the Registration
Statement of which this Prospects is a part.

                         BOOK-ENTRY; DELIVERY AND FORM
 
THE GLOBAL NOTES
 
  Exchange Notes will be issued in the form of one or more registered notes in
global form, without interest coupons (collectively, the "Global Notes"). The
Global Notes will be deposited on the date of the closing of the Exchange
Offer (the "Closing Date") with, or on behalf of, The Depository Trust Company
("DTC") and registered in the name of Cede & Co., as nominee of DTC, or will
remain in the custody of the Trustee pursuant to the FAST Balance Certificate
Agreement between DTC and the Trustee.
 
  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 ("Certificated Notes") except in the
limited circumstances described below.
 
  All interests in the Global Notes may be subject to the procedures and
requirements of DTC.
 
CERTAIN BOOK-ENTRY PROCEDURES FOR THE GLOBAL NOTES
 
  The descriptions of the operations and procedures of DTC set forth below are
provided solely as a matter of convenience. These operations and procedures
are solely within the control of DTC and are subject to change by it from time
to time. The Company takes no responsibility for these operations or
procedures, and investors are urged to contact DTC or its participants
directly to discuss these matters.
 
  DTC has advised the Company that it is (i) a limited purpose trust company
organized under the laws of the State of New York, (ii) a "banking
organization" within the meaning of the New York Banking Law, (iii) a member
of the Federal Reserve System, (iv) a "clearing corporation" within the
meaning of the Uniform Commercial Code, as amended, and (v) a "clearing
agency" registered pursuant to Section 17A of the Exchange Act. DTC was
created to hold securities for its participants (collectively, the
"Participants") and facilitates the clearance and settlement of securities
transactions between Participants through electronic book-entry changes to the
accounts of its Participants, thereby eliminating the need for physical
transfer and delivery of certificates. DTC's Participants include securities
brokers and dealers, banks and trust companies, clearing corporations and
certain other organizations. Indirect access to DTC's system is also available
to other entities such as banks, brokers, dealers and trust companies
(collectively, the "Indirect Participants") that clear through or maintain a
custodial relationship with a Participant, either directly or indirectly.
Investors who are not Participants may beneficially own securities held by or
on behalf of DTC only through Participants or Indirect Participants.
 
  The Company expects that pursuant to procedures established by DTC (i) upon
deposit of the Global Notes, DTC will credit the accounts of Participants with
an interest in the Global Notes and (ii) ownership of the Notes will be shown
on, and the transfer of ownership thereof will be effected only through,
records maintained by DTC (with respect to the interests of Participants) and
the records of Participants and the Indirect Participants (with respect to the
interests of persons other than Participants).
 
  The laws of some jurisdictions may require that certain purchasers of
securities take physical delivery of such securities in definitive form.
Accordingly, the ability to transfer interests in the Notes represented by the
Global Notes to such persons may be limited. In addition, because DTC can act
only on behalf of its Participants, who in turn act on behalf of persons who
hold interests through Participants, the ability of a person having an
interest in Notes represented by the Global Notes to pledge or transfer such
interest to persons or entities that do not participate in DTC's system, or to
otherwise take actions in respect of such interest, may be affected by the
lack of a physical definitive security in respect of such interest.
 
                                      112
<PAGE>
 
  So long as DTC or its nominee is the registered owner of the Global Notes,
DTC or such nominee, as the case may be, will be considered the sole owner or
holder of the Notes represented by the Global Notes for all purposes under the
Indenture. Except as provided below, owners of beneficial interests in the
Global Notes will not be entitled to have Notes represented by such Global
Notes registered in their names, will not receive or be entitled to receive
physical delivery of Certificated Notes, and will not be considered the owners
or holders thereof under the Indenture for any purpose, including with respect
to the giving of any direction, instruction or approval to the Trustee
thereunder. Accordingly, each holder owning a beneficial interest in the
Global Notes must rely on the procedures of DTC and, if such holder is not a
Participant or an Indirect Participant, on the procedures of the Participant
through which such holder owns its interest, to exercise any rights of a
holder of Notes under the Indenture or such Global Notes. The Company
understands that under existing industry practice, in the event that the
Company requests any action of holders of Notes, or a holder that is an owner
of a beneficial interest in the Global Notes desires to take any action that
DTC, as the holder of such Global Notes, is entitled to take, DTC would
authorize the Participants to take such action and the Participants would
authorize holders owning through such Participants to take such action or
would otherwise act upon the instruction of such holders. Neither the Company
nor the Trustee will have any responsibility or liability for any aspect of
the records relating to or payments made on account of Notes by DTC, or for
maintaining, supervising or reviewing any records of DTC relating to such
Notes.
 
  Payments with respect to the principal of, and premium, if any, Liquidated
Damages, if any, and interest on, any Notes represented by the Global Notes
registered in the name of DTC or its nominee on the applicable record date
will be payable by the Trustee to or at the direction of DTC or its nominee in
its capacity as the registered holder of the Global Notes representing such
Notes under the Indenture. Under the terms of the Indenture, the Company and
the Trustee may treat the persons in whose names the Notes, including the
Global Notes, are registered as the owners thereof for the purpose of
receiving payment thereon and for any and all other purposes whatsoever.
Accordingly, neither the Company nor the Trustee has or will have any
responsibility or liability for the payment of such amounts to owners of
beneficial interests in the Global Notes (including principal, premium, if
any, Liquidated Damages, if any, and interest). Payments by the Participants
and the Indirect Participants to the owners of beneficial interests in the
Global Notes will be governed by standing instructions and customary industry
practice and will be the responsibility of the Participants or the Indirect
Participants and DTC.
 
  Transfers between Participants in DTC will be effected in accordance with
DTC's procedures, and will be settled in same-day funds.
 
CERTIFICATED NOTES
 
  If (i) the Company notifies the Trustee in writing that DTC is no longer
willing or able to act as a depositary or DTC ceases to be registered as a
clearing agency under the Exchange Act and a successor depositary is not
appointed within 90 days of such notice or cessation, (ii) the Company, at its
option, notifies the Trustee in writing that it elects to cause the issuance
of Notes in definitive form under the Indenture or (iii) upon the occurrence
of certain other events as provided in the Indenture, then, upon surrender by
DTC of the Global Notes, Certificated Notes will be issued to each person that
DTC identifies as the beneficial owner of the Notes represented by the Global
Notes. Upon any such issuance, the Trustee is required to register such
Certificated Notes in the name of such person or persons (or the nominee of
any thereof) and cause the same to be delivered thereto.
 
  Neither the Company nor the Trustee shall be liable for any delay by DTC or
any Participant or Indirect Participant in identifying the beneficial owners
of the related Notes and each such person may conclusively rely on, and shall
be protected in relying on, instructions from DTC for all purposes (including
with respect to the registration and delivery, and the respective principal
amounts, of the Notes to be issued).

                CERTAIN UNITED STATES FEDERAL TAX CONSEQUENCES
 
  The following is a summary of certain United States federal tax consequences
to holders of the Original Notes of (i) the exchange of the Original Notes for
the Exchange Notes and (ii) the ownership and disposition of the Exchange
Notes. Except where noted, the summary deals only with Exchange Notes held as
capital assets within the meaning of Section 1221 of the Internal Revenue Code
of 1986, as amended (the "Code"). As used herein, the term "Non-U.S. Holder"
means any person or entity that is not a United States holder ("U.S. Holder").
A U.S. Holder is any beneficial owner of an Exchange Note that is (i) an
individual who is a citizen or resident of the United States, (ii) a
corporation or partnership created or organized in or under the laws of the
United States or any state or political subdivision thereof, (iii) an estate
the income of which is subject to United States federal income taxation
regardless of its source, and (iv) a trust which is subject to the supervision
of a court within the United States and the control of a United States person
as described in Section 7701(a)(30) of the Code.
 
  The following summary is based upon the provisions of the Code, and on
regulations, rulings and judicial decisions thereunder as of the date hereof,
and does not address any state, local or foreign tax consequences. This
summary does not discuss all aspects of United States federal taxation which
may be important to particular holders in light of their individual investment
circumstances, such as Exchange Notes held by investors subject to special tax
rules (e.g. financial institutions, insurance companies, broker-dealers, tax-
exempt organizations and private foundations) or to persons that will hold the
Exchange Notes as part of a straddle, hedge, or synthetic security transaction
for United States federal income tax purposes, all of whom may be subject to
tax rules that differ significantly from those summarized below. Special rules
may also apply to certain Non-U.S. Holders, such as "controlled foreign
corporations," "passive foreign investment companies" and "foreign personal
holding companies." Finally, prospective holders of Exchange Notes should be
aware that tax laws frequently change. When these changes occur, the statutes,
regulations, rulings and judicial decisions giving rise to such changes may
have a retroactive effect. Accordingly, there can be no assurance that future
changes in such tax laws will not cause the consequences of the exchange of
the Original Notes for the Exchange Notes or the ownership and disposition of
the Exchange Notes to differ significantly from the consequences summarized
below. HOLDERS OF EXCHANGE NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS
CONCERNING THE UNITED STATES FEDERAL TAX CONSEQUENCES IN LIGHT OF THEIR
PARTICULAR SITUATIONS AS WELL AS ANY CONSEQUENCES ARISING UNDER ANY STATE,
LOCAL, FOREIGN OR OTHER LAWS OR ANY APPLICABLE TAX TREATIES, WHICH MAY PROVIDE
FOR A LOWER RATE OF WITHHOLDING TAX, EXEMPTION FROM OR REDUCTION OF BRANCH
PROFITS TAX, OR OTHER RULES DIFFERENT FROM THOSE DESCRIBED BELOW.
 
EXCHANGE OFFER
 
  The exchange of Original Notes for Exchange Notes pursuant to the Exchange
Offer should be treated as a continuation of the corresponding Original Notes
because the terms of the Exchange Notes are not materially different from the
terms of the Original Notes. Accordingly, such exchange should not constitute
a taxable event and, therefore, (i) no gain or loss should be realized upon
receipt of an Exchange Note, (ii) the holding period of the Exchange Notes
should include the holding period of the Original Note exchanged therefor and
(iii) the adjusted tax basis of the Exchange Note should be the same as the
adjusted tax basis of the Original Note exchanged therefor immediately before
the exchange.

NON-U.S. HOLDERS
 
 United States Withholding Tax
 
  Under present United States federal income and estate tax law, and subject
to the discussion below concerning backup withholding:
 
    (a) no withholding of United States federal income tax will be required
  with respect to the payment by the Company or any paying agent of principal
  or interest on an Exchange Note owned by a Non-U.S. Holder, provided that
  (i) the beneficial owner does not actually or constructively own 10% or
  more of the total combined voting power of all classes of stock of the
  Company entitled to vote within the meaning of section 871(h)(3) of the
  Code and the regulations thereunder, (ii) the beneficial owner is not a
  controlled foreign corporation that is related to the Company through stock
  ownership, (iii) the beneficial owner is not a bank whose receipt of
  interest on an Exchange Note is described in section 881(c)(3)(A) of the
  Code and (iv) the beneficial owner satisfies the ownership statement
  requirement (described generally below) set forth in section 871(h) and
  section 881(c) of the Code and the regulations thereunder;
 
    (b) no withholding of United States federal income tax will be required
  with respect to any gain or income realized by a Non-U.S. Holder upon the
  sale, exchange, retirement or other disposition of an Exchange Note; and
 
    (c) an Exchange Note beneficially owned by an individual who at the time
  of death is a Non-U.S. Holder will not be subject to United States federal
  estate tax as a result of such individual's death, provided that such
  individual does not actually or constructively own 10% or more of the total
  combined voting power of all classes of stock of the Company entitled to
  vote within the meaning of section 871(h)(3) of the Code and provided that
  the interest payments with respect to such Exchange Note would not have
  been, if received at the time of such individual's death, effectively
  connected with the conduct of a United States trade or business by such
  individual.
 
  To satisfy the requirement referred to in (a)(iv) above, the beneficial
owner of such Exchange Note, or a financial institution holding the Exchange
Note on behalf of such owner, must provide, in accordance with specified
procedures, a paying agent of the Company with a statement to the effect that
the beneficial owner is not a United States person. Currently, these
requirements will be met if (1) the beneficial owner provides his name and
address, and certifies, under penalties of perjury, that he is not a United
States person (which certification may be made on an Internal Revenue Service
("IRS") Form W-8 (or successor form)) or (2) a financial institution holding
the Exchange Note on behalf of the beneficial owner certifies, under penalties
of perjury, that such statement has been received by it and furnishes a paying
agent with a copy thereof.
 
  If a Non-U.S. Holder cannot satisfy the requirements of the "portfolio
interest" exception described in (a) above, payments of interest made to such
Non-U.S. Holder will be subject to a 30% withholding tax unless the beneficial
owner of the Exchange Note provides the Company or its paying agent, as the
case may be, with a properly executed (1) IRS Form 1001 (or successor form)
claiming an exemption from (or a reduction in) withholding under the benefit
of an applicable tax treaty or (2) IRS Form 4224 (or successor form) stating
that interest paid on the Exchange Note is not subject to withholding tax
because it is effectively connected with the beneficial owner's conduct of a
trade or business in the United States. Under recently finalized Treasury
Regulations, the benefit of an applicable tax treaty may, in certain
circumstances, and subject to significant limitations under the Code, be
claimed by the foreign partners of a foreign partnership that holds the
Exchange Notes. Foreign partners are urged to consult their own tax advisors
to determine whether they are eligible to claim such benefits.
 
                                      115
<PAGE>
 
  If a Non-U.S. Holder is engaged in a trade or business in the United States
and interest on the Exchange Note is effectively connected with the conduct of
such trade or business, the Non-U.S. Holder, although exempt from the
withholding tax discussed above, will be subject to United States federal
income tax on such interest on a net income basis in the same manner as if it
were a U.S. Holder. In addition, if such holder is a foreign corporation, it
may be subject to a branch profits tax equal to 30% (or lower applicable
treaty rate) of its effectively connected earnings and profits for the taxable
year, subject to adjustments. For this purpose, interest on an Exchange Note
will be included in such foreign corporation's earnings and profits.
 
  Any gain or income realized upon the sale, exchange, retirement or other
disposition of an Exchange Note generally will not be subject to United States
federal income tax unless (i) such gain or income is effectively connected
with a trade or business in the United States of the Non-U.S. Holder, (ii) in
the case of a Non-U.S. Holder who is an individual, such individual is present
in the United States for 183 days or more in the taxable year of such sale,
exchange, retirement or other disposition, and certain other conditions are
met, or (iii) the Non-U.S. Holder is subject to tax pursuant to the provisions
of U.S. tax law applicable to certain U.S. expatriates.
 
INFORMATION, REPORTING AND BACKUP WITHHOLDING
 
  In general, no information reporting or backup withholding will be required
with respect to payments made by the Company or any paying agent to Non-U.S.
Holders if a statement described in (a)(iv) above has been received (and the
payor does not have actual knowledge that the beneficial owner is a United
States person).
 
  In addition, backup withholding and information reporting may apply to the
proceeds of the sale of an Exchange Note within the United States or conducted
through certain U.S. related financial intermediaries unless the statement
described in (a)(iv) above has been received (and the payor does not have
actual knowledge that the beneficial owner is a United States person) or the
holder otherwise establishes an exemption.
 
  Any amounts withheld under the backup withholding rules will be allowed as a
refund or a credit against such holder's United States federal income tax
liability provided the required information is furnished to the IRS and
certain procedures are followed.
 
PROSPECTIVE FINAL REGULATIONS
 
  On October 6, 1997, new Treasury Regulations ("New Regulations") were issued
that modify the requirements imposed on a Non-U.S. Holder and certain
intermediaries for establishing the recipient's status as a Non-U.S. Holder
eligible for exemption from or reduction in United States withholding tax and
backup withholding described above. In general, the New Regulations do not
significantly alter the substantive withholding and information reporting
requirements but rather unify current certification procedures and forms and
clarify reliance standards. The New Regulations are generally effective for
payments made after December 31, 1999, subject to certain transition rules. In
addition, the New Regulations impose different conditions on the ability of
financial intermediaries acting for a Non-U.S. Holder to provide
certifications on behalf of the Non-U.S. Holder, which may include entering
into an agreement with the IRS to audit certain documentation with respect to
such certifications. Non-U.S. Holders should consult their own tax advisors to
determine the effects of the application of the New Regulations to their
particular circumstances.

                             PLAN OF DISTRIBUTION
 
  Each broker-dealer that receives Exchange Notes for its own account pursuant
to the Exchange Offers must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes. This Prospectus, as it may
be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Notes received in exchange for Original
Notes where such Original Notes were acquired as a result of market-making
activities or other trading activities. The Company has agreed that for a
period of 180 days after the Expiration Date, it will make this Prospectus, as
amended or supplemented, available to any broker-dealer for use in connection
with any such resale. In addition, for 90 days after the date of this
Prospectus, all dealers effecting transactions in the Exchange Notes may be
required to deliver a prospectus.
 
  The Company will not receive any proceeds from any sale of Exchange Notes by
broker-dealers. Exchange Notes received by broker-dealers for their own
account pursuant to the Exchange Offers 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 Exchange Notes or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such 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 such broker-dealer and/or purchasers of any such Exchange
Notes. Any broker-dealer that resells Exchange Notes that were received by it
for its own account pursuant to the Exchange Offers and any broker or dealer
that participates in a distribution of such Exchange Notes may be deemed to be
an "underwriter" within the meaning of the Securities Act and any profit on
any such resale of Exchange Notes and any commissions or concessions received
by any such 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 after the Expiration Date the Company will promptly
send additional copies of this Prospectus and any amendment or supplement to
this Prospectus to any broker-dealer that requests such documents in the
Letter of Transmittal. The Company has agreed to pay all expenses incident to
the Exchange Offer (including the expenses of one counsel for the holders of
the Original Notes), other than commissions or concessions of any broker-
dealers, and will indemnify the holders of the Notes (including any broker-
dealers) against certain liabilities, including liabilities under the
Securities Act.
 
                                 LEGAL MATTERS
 
  The validity of the Exchange Notes offered hereby will be passed upon for
the Company by Testa, Hurwitz & Thibeault, LLP, Boston, Massachusetts.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of Advanstar Communications Inc.:
 
  We have audited the accompanying consolidated balance sheets as of December
31, 1996 and 1997 and the consolidated statements of operations, shareholder's
equity and cash flows of Advanstar Communications Inc. (a New York Corporation
and wholly-owned subsidiary of Advanstar Holdings, Inc.) and subsidiaries and
its predecessor for the year ended December 31, 1995, the five-month period
ended May 31, 1996, the seven-month period ended December 31, 1996 and the
year ended December 31, 1997. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Advanstar
Communications Inc. and subsidiaries and its predecessor as of December 31,
1996 and 1997, and the results of their operations and their cash flows for
the year ended December 31, 1995, the five-month period ended May 31, 1996,
the seven-month period ended December 31, 1996, and the year ended December
31, 1997, in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                          DECEMBER 31, 1996 AND 1997
 
1. DESCRIPTION OF BUSINESS AND ACQUISITION:
 
 Description of Business
 
  The accompanying consolidated financial statements include the accounts of
Advanstar Communications Inc. (a New York corporation) and its wholly owned
subsidiaries, collectively referred to as the Company. The Company is a wholly
owned subsidiary of Advanstar Holdings, Inc. (Holdings). Holdings has limited
operations and its activities are solely on behalf of the Company.
Accordingly, all assets, liabilities, revenues and expenses of Holdings are
reflected in the financial statements of the Company. All intercompany
transactions have been eliminated in consolidation.
 
  The Company publishes controlled circulation trade and professional
periodicals; operates and manages expositions, trade shows and conferences;
and markets a broad range of marketing, direct mail and database products and
services.
 
 Acquisition of the Company
 
  On May 31, 1996, Holdings acquired in a cash merger the stock and became the
sole shareholder of the Company. Holdings was established expressly for the
purpose of effecting the acquisition of the Company (the HFCP III Acquisition)
and is wholly owned by AHI Advanstar. The aggregate purchase price for the
Company was approximately $267.0 million, consisting of $97.0 million cash
equity, $144.0 million debt and approximately $26.0 million of assumed
liabilities and transaction costs.
 
  Due to the effects of the HFCP III Acquisition on the recorded bases of
goodwill, intangibles, property and shareholder's equity, as discussed below
and in Note 4, the financial statements prior to and subsequent to the HFCP
III Acquisition are not comparable. Periods prior to June 1, 1996 represent
the accounts of the Predecessor.
 
 Other Acquired Entities
 
  During 1995, 1996 and 1997, the Company purchased certain publication and
exposition properties for an aggregate purchase price of $.5 million, $18.3
million and $39.7, respectively. The cost of these acquired entities in excess
of the fair market value of net assets acquired has been recorded as goodwill
and intangibles. The pro forma affect of these acquisitions on the results of
operations was not material.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Cash and Cash Equivalents
 
  Cash and cash equivalents include cash on deposit and highly liquid
investments with original maturities of three months or less. Cash equivalents
are stated at cost, which approximates their fair market value. The effect of
foreign currency translation on cash held by foreign operations is immaterial.
 
 Prepaid Expenses and Other Current Assets
 
  Prepaid expenses consist primarily of prepaid exposition expenses, prepaid
publication production costs and miscellaneous deposits. Exposition and
publication expenses are charged to operations at the time of the occurrence
of the related exposition and at the time of publication issuance. Other
current assets consist of paper inventories and notes receivable.

 Property, Plant and Equipment
 
  Property, plant and equipment additions are recorded at cost. For financial
reporting purposes, depreciation is provided on a straight-line basis over the
following estimated useful lives:

                                                                   USEFUL LIVES

   <S>                                                             <C>
   Land improvements..............................................  10-15 years
   Buildings......................................................  20-40 years
   Furniture, machinery and equipment.............................   3-10 years
   Leasehold improvements......................................... Life of lease
</TABLE>
 
For tax reporting purposes, certain assets have different estimated useful
lives.
 
 Goodwill
 
  All acquisitions have been accounted for using the purchase method of
accounting, with the purchase price in excess of the fair values of specific
identifiable tangible and intangible assets acquired allocated to goodwill.
 
  Goodwill, which is being amortized on a straight-line basis over an average
life of 23 years, is recorded in the accompanying consolidated balance sheet
net of accumulated amortization of $3.9 million and $11.9 million at December
31, 1996 and 1997, respectively.
 
 Intangible Assets
 
  Intangible assets related to the HFCP III Acquisition consist primarily of
advertiser, paid subscriber and trade show exhibitor lists, computer software,
the value assigned to the Company's assembled workforce and fulfillment
agreements. Such intangibles are being amortized on a straight-line basis over
3 months to 20 years. Intangible assets associated with acquired businesses
consist primarily of identifiable intangibles and are being amortized on a
straight-line basis over one to eight years. Accumulated amortization was $9.6
million and $25.6 million at December 31, 1996 and 1997, respectively.
 
 Impairment of Long-Lived Assets
 
  The Company evaluates the carrying value of long-lived assets in accordance
with SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of" to determine whether certain
circumstances may affect the estimated useful lives or the recoverability of
such assets. A number of factors, including estimated future undiscounted cash
flows associated with the long-lived asset, are considered in this
determination. The accompanying financial statements reflect no adjustments
relative to this evaluation.
 
 Revenue Recognition
 
  Exposition revenue is recognized in the accounting period in which the
exposition is conducted. Subscription revenue is recognized on a pro rata
basis as publications are issued to fulfill the subscription obligations.
Deferred revenue is recorded when cash is received in advance of providing the
related service.
 
  Deferred revenue consisted of the following at December 31 (in thousands):

                          DECEMBER 31, 1996 AND 1997
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Ultimate results could differ from these estimates.
 
 Foreign Currency Translation
 
  The Company accounts for translation investments in foreign entities in
accordance with SFAS No. 52, "Foreign Currency Translation."
 
 Reclassifications
 
  Certain amounts previously reported in the 1995 and 1996 financial
statements have been reclassified to conform to the 1997 presentation.
 
 Recently Issued Accounting Standards
 
 
  In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income." The statement requires an enterprise to
classify items of other comprehensive income by their nature in a financial
statement and display the accumulated balance of other comprehensive income
separately from retained earnings and additional paid-in capital in the equity
section of the statement of financial position. The Company will adopt this
standard during 1998. Adoption of this standard is not expected to have a
material effect on the Company.
 
  In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures About Segments of an Enterprise and Related Information." The
statement requires that a public business enterprise report financial and
descriptive information about its reportable operating segments such as a
measure of segment profit or loss, certain specific revenue and expense items,
and segment assets. The Company will adopt this standard during 1998 and is
currently analyzing the impact it will have on the disclosures in its
financial statements.
 
3. DEBT:
 
  In connection with the HFCP III Acquisition, all existing debt at May 31,
1996 was paid in full, and the Company entered into a credit agreement
securing new debt in the form of two tranche term loan notes and a revolving
credit loan. During 1997, the Company obtained an amendment to its credit
facility which provided $40 million of a new tranche term loan. The Company
also expanded its revolving credit loan capacity during 1997 from $25.0
million to $35.0 million. The credit facility was used to finance acquisitions
completed late in 1996 and early 1997.

 Stock Option Plan
 
  In November 1996, Holdings implemented a nonqualified stock option plan (the
Plan) under which certain members of the Company's management were granted
options to purchase shares of Holdings' common stock. The exercise price for
these options was $10 per share initially, and increases at a 10% annually
compounded rate. The term of the options runs for ten years, with options
vesting 20% in each of the first five years of the option term. Options become
immediately exercisable upon a change of control of Holdings, as defined, or
at the discretion of Holdings' Board of Directors. If the Company does not
complete an initial public offering by January 1, 2001, option holders may
agree with the Company to sell the shares under option to the Company at a
fair market value price to be determined by the Board of Directors. However,
the Company is not obligated to agree to any such repurchase under the terms
of the Plan. In addition, the Company has certain repurchase rights under the
Plan. Under the Plan, up to 745,200 options may be granted at the discretion
of the Holdings' Board of Directors.
 
  Because of the variable features of the Plan, the Company measures the
difference between the exercise price of the options and the fair value of the
shares under option at the end of each fiscal period, and recognizes
compensation expense to provide for such difference. As of December 31, 1996
and 1997 no compensation expense was required to be recognized.
 
  A summary of stock option activity under the Plan is as follows:

8. EVENTS SUBSEQUENT TO THE DATE OF REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
(UNAUDITED):
 
 VSDA and TelExpo Acquisitions
 
  In February and March, 1998, the Company borrowed an additional $14.0
million under its revolving credit line. $7.0 million was used as a portion of
the approximately $9.8 million purchase price for a 50% interest in The Video
Software Dealers Association's (VSDA) annual industry exposition. As the
Company will exert management and operational control over the joint venture,
this entity will be consolidated and accounted for under the purchase method
of accounting.
 
  The remaining $7.0 million borrowed in 1998 was used to acquire TelExpo, a
Brazilian telecommunications exposition. This transaction closed in the first
quarter 1998 and will be accounted for under the purchase method of
accounting.
 
 MAGIC Acquisition
 
  On April 30, 1998, the Company acquired Men's Apparel Guild in California,
Inc. (MAGIC), which operates apparel expositions. The purchase price was
approximately $230.2 million in cash. Concurrent with the MAGIC Acquisition,

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                          DECEMBER 31, 1996 AND 1997
 
9. SUPPLEMENTAL GUARANTOR CONDENSED CONSOLIDATING FINANCIAL STATEMENTS:
 
 Basis of presentation
 
  The Notes will be fully and unconditionally guaranteed on a senior
subordinated basis, jointly and severally, by the Company's wholly-owned
domestic subsidiaries (the Subsidiary Guarantors) and by Holdings. As
discussed in Note 1, the Company is a wholly-owned subsidiary of Holdings. The
limited activities of Holdings are exclusively for the benefit of the Company.
Accordingly, the financial results of Holdings are included in the results of
the Company. Holding's financial information has not been provided herein as
it was not deemed to be material. The Subsidiary Guarantors are Art
Expositions International, Inc.; Expocon Management Associates, Inc.; On
Demand Marketing, Inc.; Men's Apparel Guild in California, Inc.; Magic Kids,
Inc.; Technology Events Company, LLC and Applied Business teleCommunications.
The condensed consolidating financial statements of the Guarantors are
presented below and should be read in connection with the Consolidated
Financial Statements of the Company. Separate financial statements of the
Guarantors are not presented because the Guarantors are jointly, severally and
unconditionally liable under the guarantees and the Company believes the
condensed consolidating financial statements presented are more meaningful in
understanding the financial position of the Guarantors.
 
  There are no significant restrictions on the ability of the Subsidiary
Guarantors to make distributions to the Company. Condensed consolidating
financial information has not been presented for 1996 and 1995 because the
Company had no non-guarantor subsidiaries in 1996 and 1995.

                                  (UNAUDITED)
 
1. BASIS OF PRESENTATION:
 
  The accompanying condensed consolidated financial statements have been
prepared by Advanstar Communications Inc. (the Company), without audit,
pursuant to the rules and regulations of the Securities and Exchange
Commission. The information furnished in the condensed consolidated financial
statements includes normal recurring adjustments and reflects all adjustments
which are, in the opinion of management, necessary for a fair presentation of
such financial statements. Certain information and footnote disclosures
normally included in financial statements prepared in accordance with
generally accepted accounting principles have been condensed or omitted
pursuant to such rules and regulations. Although the Company believes that the
disclosures are adequate to make the information presented not misleading, it
is suggested that these condensed consolidated financial statements be read in
conjunction with the audited financial statements and the notes thereto
included in the Company's Registration Statement on Form S-4, relating to the
Company's exchange offer for its outstanding 9 1/4% Senior Subordinated Notes.
 
  Revenues and operating results for the three months ended March 31, 1998 and
1997 are not necessarily indicative of the results to be expected for the full
year.
 
2. ACQUISITIONS AND FINANCING TRANSACTIONS:
 
 MAGIC Acquisition
 
  On April 30, 1998, the Company acquired Men's Apparel Guild in California,
Inc. (MAGIC), which operates apparel expositions. The purchase price was
approximately $230.2 million in cash. Concurrent with the MAGIC Acquisition,
the Company renegotiated its credit agreement to provide additional borrowing
capacity and issued $150.0 million of 9 1/4% Senior Subordinated Notes (see
Note 3). On the Closing Date, the Company also received an additional equity
contribution from its parent of approximately $70.0 million.
 
 VSDA and TelExpo Acquisitions
 
  In February and March, 1998, the Company borrowed an additional $14.0
million under its revolving credit line. $7.0 million was used as a portion of
the approximately $9.8 million purchase prices for a 50% interest in The Video
Software Dealers Association's (VSDA) annual industry exposition. As the
Company will exert management and operational control over the joint venture,
this entity will be consolidated and accounted for under the purchase method
of accounting.
 
  The remaining $7.0 million borrowed in 1998 was used to acquire TelExpo, a
Brazilian telecommunications exposition. This transaction closed in the first
quarter 1998 and was accounted for under the purchase method of accounting,
based on preliminary allocations.
 
 Other 1998 Acquisitions
 
  In the first quarter of 1998, the Company completed three other acquisitions
of exposition and publishing properties, with a cumulative purchase price
totaling approximately $12.0 million. In addition, since March 31, 1998, the
Company has completed two additional acquisitions with a cumulative purchase
price totalling approximately $24.6 million and has signed a letter of intent
and expects to complete an additional transaction in June/July 1998 with an
estimated purchase price of approximately $6.5 million.
 
 Pro Forma Financial Information
 
  The aforementioned acquisitions have been or will be accounted for as
purchases and, accordingly, the acquired entities' assets and liabilities have
been or will be recorded at fair values as of the acquisition dates.

3. DEBT AND AMENDED CREDIT FACILITY:
 
  In order to facilitate the acquisition of MAGIC and to provide greater
flexibility in pursuing its growth strategy, on April 30, 1998, the Company
issued $150 million of its 9 1/4% Senior Subordinated Notes (the Notes) and
amended its existing senior credit facility (the "Original Credit Facility"
and, as amended, the "Amended Credit Facility") with a syndicate of banks, by
increasing its borrowing capacity thereunder from $215.0 million under the
Original Credit Facility to $270.0 million under the Amended Credit Facility.
 
 Description of Amended Credit Facility
 
  The Amended Credit Facility will consist of three components: a 5 1/2-year
term loan in an aggregate principal amount equal to $85 million, a 7-year term
loan in an aggregate principal amount
 
                                     F-24
<PAGE>
 
                ADVANSTAR COMMUNICATIONS, INC. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
                                  (UNAUDITED)

equal to $125 million, and a 5 1/2-year revolving credit facility in the
maximum available amount of $60 million.
 
  The obligations of the Company under the Amended Credit Facility will be
guaranteed by the parent and will be collateralized by substantially all
tangible and intangible assets and pledges of the capital stock of the Company
and substantially all of the Company's subsidiaries (including MAGIC).
 
  The term loans will be amortized in quarterly installments totaling
approximately $1.5 million in 1998, $7.0 million in 1999, $13.5 million in
2000 and $17.0 million in 2001, $19.5 million 2002, $31.5 million in 2003,
$60.25 million in 2004 and $59.75 in 2005. Principal amounts outstanding under
the revolving credit facility will be due and payable in full at maturity,
approximately 5 1/2 years after April 30, 1998. Interest on outstanding
borrowings will accrue, at floating variable rates, as defined, approximating
a blended average rate of 8.1% on April 30, 1998. In addition, the Company
will be required to pay a commitment fee under the revolving credit facility
in respect of the unutilized commitments thereunder at a rate that will vary
based upon operating performance targets and step-downs set forth in the
agreement, subject to a maximum commitment fee rate of 0.50% per annum.
 
  The Company will be required to apply certain amounts to prepay the term
loans, including (i) proceeds from certain issuances of equity or indebtedness
by the Company, its parent, or its subsidiaries; (ii) the net cash proceeds of
certain sales or other dispositions by the Company or any of its subsidiaries
of any assets; and (iii) 50% of excess cash flow (as defined) for each fiscal
year. The Company will also have the right to optionally prepay the loans
under the Amended Credit Facility, without premium, in whole or in part.
Amounts applied as prepayments of the revolving credit facility may be
reborrowed; amounts prepaid in respect of the term loans may not.
 
  Under the Amended Credit Facility, restrictive financial covenants include a
minimum fixed charge coverage ratio and a maximum leverage ratio.
 
 Description of Notes
 
  The Notes are unsecured, senior subordinated obligations of the Company,
limited to $150.0 million aggregate principal amount, and will mature on May
1, 2008. Each Note will bear interest at the 9 1/4%, payable semi-annually.
The Notes will be redeemable at the Company's option after May 1, 2003 through
April 30, 2006 at specified premiums, and at par thereafter. A portion of the
Notes may be redeemed at a premium prior to May 1, 2001 with proceeds of

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
                                  (UNAUDITED)
 
5. COMMITMENTS AND CONTINGENCIES:
 
 Litigation
 
  The Company is a defendant in legal proceedings arising in the ordinary
course of business. Although the outcome of these proceedings cannot presently
be determined, in the opinion of management, disposition of these proceedings
will not have a material effect on the results of operations or financial
position of the Company.
 
6. SUPPLEMENTAL GUARANTOR CONDENSED CONSOLIDATING FINANCIAL STATEMENTS:
 
 Basis of presentation
 
  The Notes will be fully and unconditionally guaranteed on a senior
subordinated basis, jointly and severally, by the Company's wholly-owned
domestic subsidiaries (the Subsidiary Guarantors) and by Holdings. The Company
is a wholly-owned subsidiary of Holdings. The limited activities of Holdings
are exclusively for the benefit of the Company. Accordingly, the financial
results of Holdings are included in the results of the Company. Holding's
financial information has not been provided herein as it was not deemed to be
material. The Subsidiary Guarantors are Art Expositions International, Inc.;
Expocon Management Associates, Inc.; On Demand Marketing, Inc.; Men's Apparel
Guild in California, Inc.; Magic Kids, Inc.; Technology Events Company, LLC
and Applied Business teleCommunications. The condensed consolidating financial
statements of the Guarantors are presented above and should be read in
connection with the Consolidated Financial Statements of the Company. Separate
financial statements of the Guarantors are not presented because the
Guarantors are jointly, severally and unconditionally liable under the
guarantees and the Company believes the condensed consolidating financial
statements presented are more meaningful in understanding the financial
position of the Guarantors.
 
  There are no significant restrictions on the ability of the Subsidiary
Guarantors to make distributions to the Company.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Men's Apparel Guild in California, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Men's
Apparel Guild in California, Inc. and subsidiary as of February 28, 1998, and
the related consolidated statements of income, shareholder's equity and cash
flows for the nine-month period ended February 28, 1998. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of Men's Apparel Guild in California, Inc. and subsidiary as of February 28,
1998, and the consolidated results of their operations and their cash flows
for the nine-month period ended February 28, 1998 in conformity with generally
accepted accounting principles.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors
Men's Apparel Guild in California, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Men's
Apparel Guild in California, Inc. and subsidiary as of May 31, 1997 and 1996,
and the related consolidated statements of income, shareholders' equity and
cash flows for each of the years in the three year period ended May 31, 1997.
These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of Men's Apparel Guild in California, Inc. and subsidiary as of May 31, 1997
and 1996, and the consolidated results of their operations and their cash
flows for each of the years in the three year period ended May 31, 1997 in
conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                FOR THE YEARS ENDED MAY 31, 1995, 1996 AND 1997
                AND FOR THE NINE MONTHS ENDED FEBRUARY 28, 1998
 
1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION:
 
  The accompanying consolidated financial statements include the accounts of
Men's Apparel Guild in California (MAGIC) and its wholly owned subsidiary,
MAGIC KIDS, INC. (MAGIC Kids), collectively referred to as the Company. All
intercompany transactions have been eliminated in consolidation.
 
 Nature of Operations
 
  The Company has produced trade shows for the men's apparel industry for over
sixty years. For each of the periods presented in the accompanying statements
of operations, including the nine months ended February 28, 1998, two trade
shows have occurred (in February and August).
 
 Basis of Presentation
 
  During fiscal 1994, as a result of a private placement offering circular,
the Company converted from a nonprofit mutual benefit corporation to a for-
profit corporation status and issued common stock to its "charter" members. In
addition, the Company issued common stock to four individuals for notes
receivable (Note 6).
 
 Joint Participation Agreement
 
  During fiscal 1995, the Company entered into a joint participation agreement
to co-sponsor a women's apparel trade show with Fairchild Publications under
the name "WWD/Magic." In accordance with the cosponsor agreement, 30% of show
net income and 50% of publication net income related to the WWD/Magic show has
been allocated to the cosponsor of the show as profit participation.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Cash Equivalents and Short-Term Investments
 
  The Company considers all highly liquid investments with an initial maturity
of three months or less to be cash equivalents and are stated at cost, which
approximates their fair market value. Short-term investments principally
include United States Treasury bills with original maturities greater than
three months and are stated at fair value. The Company places its cash, cash
equivalents and short-term investments with high-credit quality financial
institutions. At times, bank balances may be in excess of the federally
insured limit. Bank balances were in excess of federally insured limits in the
amounts of $11,395,338 for the nine-month period ended February 28, 1998 and
$5,813,723 and $7,055,031 at May 31, 1997 and 1996, respectively.
 
 Other Current Assets
 
  Other current assets consist primarily of prepaid expenses, which consists
of prepaid show costs and prepaid taxes.
 
 Property and Equipment
 
  The Company's property and equipment are recorded at cost. For financial
reporting purposes depreciation and amortization of property and equipment are
provided on the straight-line method based on the estimated useful lives of
the respective assets. Leasehold improvements are amortized over the lesser of
the useful life or the term of the lease. Maintenance and repair costs are
expensed

   Computer equipment..............................................     5 years
   Office furniture, fixtures and equipment........................     5 years
   Leasehold improvements..........................................  3-10 years
</TABLE>
 
 Intangible Assets and Other Assets
 
  Intangible assets, consisting primarily of goodwill, are stated at cost less
accumulated amortization, and are amortized on a straight-line basis over
their estimated useful lives of approximately 10 years.
 
  The Company periodically evaluates the realizability of its long-lived and
intangible assets. Based on its most recent analysis, no impairment exists at
May 31, 1997 or February 28, 1998.
 
 Revenue Recognition
 
  Revenue is recorded in the period in which the applicable shows are held.
Deferred revenue is recorded when cash is received in advance of the
applicable show.
 
 Income Taxes
 
  The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes," which requires recognition of deferred tax
liabilities and assets for the expected future tax consequences of events that
have been included in the financial statements or tax returns. Under this
method, deferred tax liabilities and assets are determined based on the
difference between the financial statement and the tax bases of assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse. If required, valuation allowances would
be established to reduce deferred tax assets to the amount expected to be
realized.
 
 Long-Term Investments
 
  The Company accounts for its long-term investments in accordance with SFAS
No. 115, "Accounting for Certain Investments in Debt and Equity Securities."
For the years ended May 31, 1996 and 1997, all of the Company's investments
have been classified as available-for-sale. The Company utilizes specific
identification in computing realized and unrealized gains and losses on
investments. At May 31, 1996 and 1997, the Company had unrealized losses on
investments of $61,968 and $34,559, respectively, which is included as a
separate component of equity. The long-term investments had a fair market
value of $7,502,131 and a cost basis of $7,564,099 as of May 31, 1996 and a
fair market value of $7,909,644 and a cost basis of $7,944,203 as of May 31,
1997. The Company's available-for-sale investments at May 31, 1997 consist
primarily of tax advantaged municipal bonds (54%), United States Treasury
Notes (36%), money market funds (6%) and corporate bonds (4%). Of the
investments, other than money market funds, 23% will mature in one year or
less, 38% in two years, 30% in three years and 9% mature in four or more
years.
 
  During February 1998, the Company liquidated its investment portfolio which
approximated book value. At February 28, 1998, the Company is invested in
highly liquid investments with maturities of less than 60 days.

 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent liabilities at the date of the financial statements,
and the reported amounts of revenues and expenses during the reporting period.
Ultimate results could differ from the estimates.
 
 Recently Issued Accounting Standard
 
  In March 1997, the Financial Accounting Standards Board issued SFAS No. 129,
"Disclosure of Information About Capital Structure." The accounting or
disclosure requirements of this statement are effective for the Company's
fiscal year 1998. The Company is reviewing the potential impact of adopting
the new accounting standard.
 
  During June 1997, the Financial Accounting Standards Board released
Statement of Financial Accounting Standards (SFAS) No. 130, "Reporting
Comprehensive Income," effective for fiscal years beginning after December 15,
1997. SFAS No. 130 establishes standards for the reporting and display in the
financial statements of total net income and the components of all other
nonowner changes in equity, referred to as comprehensive income. The Company
will adopt SFAS No. 130 in 1998 and has not yet determined the impact it will
have on the disclosures in its financial statements.
 
  During June 1997, the Financial Accounting Standards Board released
Statement of Financial Accounting Standards (SFAS) No. 131, "Disclosures about
Segments of an Enterprise and Related Information," effective for fiscal years
beginning after December 15, 1997. SFAS No. 131 requires disclosure of
business and geographic segments in the consolidated financial statements of
the Company. The Company will adopt SFAS No. 131 in 1998 and is currently
analyzing the impact it will have on the disclosures in its financial
statements.

  The provision for income taxes differs from the amount obtained by applying
the federal statutory income tax rate primarily due to tax-exempt interest and
state income taxes.
 
  The tax effected amounts of temporary differences which give rise to the
Company's net deferred tax asset are as follows:

  No valuation allowance has been established since net deferred tax assets
are expected to be realized through either expected future taxable income or
taxable income in prior carryback years. At February 28, 1998, approximately
$4.2 million is included in accrued liabilities for income taxes payable.
 
4. BENEFIT PLANS:
 
  During fiscal 1994, the Company implemented a defined contribution plan
covering all full-time employees. The Company's contributions to this plan for
the years ended May 31, 1995, 1996 and 1997 and for the nine-month period
ended February 28, 1998 were $55,988, $40,365, $97,531 and $63,800,
respectively.
 
  In addition, the Company had a noncontributory defined benefit pension plan
(the Plan) which covered all full-time employees through May 31, 1993.
Effective May 31, 1993, the Company terminated this Plan. Upon formal approval
from the Internal Revenue Service, the Company distributed the assets of the
Plan during the year ended May 31, 1996.
 
5. SHAREHOLDERS' EQUITY:
 
  In July 1997, the Company's Board of Directors approved a stock redemption
plan under which a total amount not to exceed $50.0 million may be
repurchased. These repurchases are made through a "dutch auction" program at a
price range of $2,080 to $2,500 per share subject to certain restrictions.
Total shares repurchased during the nine month period ended February 28, 1998
were 6,477 for approximately $16.1 million including certain transaction
costs.
 
6. RELATED-PARTY TRANSACTIONS:
 
  During fiscal year 1994, the Company issued 2,000 shares of common stock to
four board members who were not charter members in exchange for notes
receivable which were due in three equal annual installments. Payments made
during fiscal years 1995, 1996 and 1997 on these notes receivable totaled
$85,660, $60,933 and $16,211, respectively.

7. EXECUTIVE EMPLOYMENT AGREEMENT:
 
  On July 16, 1996, the Company entered into an Executive Employment Agreement
(the Agreement) with an officer of the Company that effectively granted the
officer stock appreciation rights (SARs) with respect to 1,000 shares of the
Company's common stock. The SARs granted by the Agreement become vested in and
exercisable by the officer in five equal installments each May 31 beginning
May 31, 1996. The SARs become fully vested and exercisable by the officer only
in the event of a change of control or if the officer's employment is
terminated. The Agreement was amended in July 1997 to provide for additional
grants of SARs based on the Company's future performance. The future
compensation expense related to this Agreement (assuming change in control at
May 31, 1998) is estimated at $6.5 million. Due to the contingent nature of
the SARs, no compensation expense was recognized as of May 31, 1996 and 1997
or February 28, 1998. No SARs have been exercised as of February 28, 1998.
 
8. COMMITMENTS AND CONTINGENCIES:
 
LEASE COMMITMENTS:
 
  The Company leases facilities and various equipment under operating leases.
Leases that expire are expected to be renewed or replaced by leases on other
properties.
 
  Future minimum rental payments as of May 31, 1997 for operating leases
having initial or remaining noncancellable lease terms in excess of one year
are as follows:

nine months ended February 28, 1998 and for the years ended May 31, 1997, 1996
and 1995, respectively.
 
  The Company was obligated under a noncancellable operating lease for its
premises which would have expired on August 31, 2000. On April 11, 1996, the
Company entered into a lease termination agreement with its landlord to vacate
its premises prior to the scheduled expiration date of August 31, 2000. The
Company paid $275,000 to relinquish it from all obligations under the lease
after September 30, 1996. Rental payments with respect to this lease were made
through September 30, 1996.
 
9. ACQUISITION BY ADVANSTAR COMMUNICATIONS INC.:
 
  On March 6, 1998, Advanstar Communications Inc. signed a merger agreement to
acquire the Company. The aggregate purchase price will consist of

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Andvanstar Communications Inc. (the "Company") is a New York Corporation.
Section 402(b) of the New York Business Corporation (" NYBCL") statute
generally provides that a company's certificate of incorporation may set forth
a provision eliminating or limiting the personal liability of its directors
for damages for any breach of duty in such capacity, provided that no such
provision shall eliminate or limit: the liability of any director if a
judgment or other final adjudication adverse to him establishes (i) that his
acts or omissions were in bad faith or involved intentional misconduct or a
knowing violation of law; or (ii) that he personally gained in fact a
financial profit or other advantage to which he was not legally entitled; or
(iii) that his acts violated section 719 of the NYBCL.
 
  In addition, section 722(a) of the NYBCL generally provides that a
corporation may indemnify officers made, or threatened to be made, a party to
an action or proceeding, other than one by or in the right of the corporation
to procure a judgment in its favor, including an action by or in the right of
any other corporation, or other enterprise, which any director or officer of
the corporation served in any capacity at the request of the corporation, by
reason of the fact that he was a director or officer of the corporation, or
served such other corporation, or other enterprise in any capacity, against
judgments, fines, amounts paid in settlement and reasonable expenses,
including attorneys fees, if such director or officer acted in good faith.
 
  Section 722(c), in general, further provides that a corporation may
indemnify any person made, or threatened to be made, a party to an action by
or in the right of the corporation to procure a judgment in its favor by
reason of the fact that he is or was a director or officer of the corporation,
or is or was serving at the request of the corporation as a director or
officer of any other corporation, or other enterprise, against amounts paid in
settlement and reasonable expenses, including attorneys fees in connection
with the defense or settlement of such action if such director or officer
acted in good faith.
 
  Generally, the Company's certificate of incorporation eliminates the
personal liability of its directors to the fullest extent permitted by the
provisions of paragraph (b) of Section 402 of the NYBCL. In addition, the
Company's bylaws indemnify its directors and officers in connection with any
proceeding, including an action by or in the right of the corporation, by
reason of the fact that such person is or was a director or officer of the
Company, or is or was serving at the request of the Company as a director,
officer, trustee, employee or agent of another corporation or other
enterprise, except in relation to matters as to which a director or officer is
adjudged to have breached his duty of care or to have acted in bad faith.
 
  Advanstar Holdings, Inc. ("Holdings") and Art Expositions International
("Art Expositions") are each Delaware corporations. The Delaware General
Corporation Law (the "DCCL") permits the indemnification by a Delaware
corporation of its directors and officers for liabilities and expenses that
they may incur in such capacities. In general, directors and officers are
indemnified with respect to actions taken in good faith in a manner reasonably
believed to be in, or not opposed to, the best interests of the Registrant,
and with respect to any criminal action proceeding, actions that the
indemnified party has no reasonable cause to believe were unlawful.
 
  Holdings' certificate of incorporation states that no director shall be
personally liable for monetary damages for breaches of fiduciary duty as a
director, except for liability (i) for any breach of the director's duty of
loyalty (ii) acts or omission not in good faith or which involve intentional
misconduct or a know violation of law (iii) under section 174 of the DGCL or
(iv) for any transaction for which the director derived any improper personal
benefit. If the DGCL is amended then liability of the director shall be
eliminated or limited to the fullest extent permitted. In general, Holdings'
bylaws indemnify any
 
                                     II-1
<PAGE>
 
person, made a party to an action, suit or proceeding by or in the right of
Holdings to procure a judgment in its favor by reason of the fact that he is
or was a director or officer against the reasonable expenses, including
attorneys' fees incurred by him in connection with the defense of such action,
except in relation to matters as to which a director or officer is adjudged to
have breached his duty of care or have acted in bad faith.
 
  Art Expositions' certificate incorporation generally provides that no
director shall be personally liable for monetary damages for breach of
fiduciary duty, except for liability (i) for breach of the duty of loyalty
(ii) acts omissions not in good faith involving intentional misconduct or
knowing violation of law (iii) under Section 174 of the DGCL (iv) for any
transaction from which the director derived any improper personal benefit. Art
Exposition's bylaws provide that directors and officers made a party to an
action, suit or proceeding by or in the right of Art Expositions to procure a
judgment in its favor by reason of the fact that he is or was a director or
officer shall be indemnified against the reasonable expenses, including
attorneys' fees, incurred in connection with the defense of such action to the
fullest extent permitted by the DGCL.
 
  Men's Apparel Guild in California, Inc. ("MAGIC"), Magic Kids, Inc. ("Magic
Kids") and Applied Business teleCommunications ("ABC") are each California
corporations. Section 204 of the California Corporations Code (the "CCC")
generally provides that articles of incorporation may set forth provisions
eliminating or limiting the personal liability of a director for monetary
damages in an action brought by or in the right of the corporation for breach
or a director's duties to the corporation and its shareholders as set forth in
Section 309 of the CCC, provided, however, that (A) such provision may not
eliminate or limit the liability of directors (i) for acts or omissions that
involve intentional misconduct or a knowing and culpable violation of law,
(ii) 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, (iii) for any transaction from
which a director derived an improper personal benefit, (iv) for acts or
omissions that show a reckless disregard for the director's duty of 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, or a risk of serious injury to the corporation or its
shareholders, (v) 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, (vi) under Section 310 of the CCC; and (B) no
such provision shall eliminate or limit the liability of an officer for any
act or omission as an offer not withstanding that the officer is also a
director or that his actions, if negligent or improper, have been ratified by
the directors.
 
  MAGIC's articles of incorporation and bylaws generally authorize that, to
the fullest extent permissible under California law and in excess of that
which is expressly permitted by Section 317 of the CCC, MAGIC shall indemnify
its directors and officers against all expenses, judgments, fines, settlements
and other amounts actually and reasonably incurred by them in connection with
any proceeding, including an action by or in the right of the corporation, by
reason of the fact that such person is or was a director or officer of the
corporation, or is or was serving at the request of the corporation as a
director, officer, trustee, employee or agent of another corporation or other
enterprise.
 
  Magic Kids' articles of incorporation provide for indemnification of its
agents (as defined in Section 317 of the CCC) through bylaw provisions,
agreements with agents, a vote of shareholders or disinterested directors or
otherwise, in excess of the indemnification otherwise permitted by Section 317
of the California Corporations Code, subject only to the applicable limits set
forth in Section 204 of the CCC with respect to actions for breach of duty to
Magic Kids and its shareholders. The liability of the directors of Magic Kids
for monetary damages shall be eliminated to the fullest extent permissible
under California law. Magic Kids' bylaws indemnify directors and officers to
the maximum extent permitted by the CCC.
 
  The articles of incorporation of ABC are silent on the topic of director and
officer indemnification. The bylaws of ABC provide for the indemnification of
its agents against expenses, judgments, fines,
 
                                     II-2
<PAGE>
 
settlements and other amounts, actually and reasonably incurred by reason such
person's having been made or having been threatened to be party to a
proceeding to the fullest extent permissible under the CCC.
 
  On Demand Marketing Inc. ("On Demand") and Expocon Management Associates
("Expocon") are each Connecticut corporations. Section 33-636 of the
Connecticut Business Corporation Act ("CBCA") provides that a corporation's
certificate of incorporation may set forth: a provision limiting the personal
liability of a director to the corporation or its shareholders for monetary
damages for breach of duty as a director to an amount that is not less than
the compensation received by the director for serving the corporation during
the year of the violation if such breach did not (i) involve a knowing and
culpable violation of law by the director, (ii) enable the director or an
associate, as defined in section 33-840, to receive an improper personal
economic gain, (iii) show a lack of good faith and a conscious disregard for
the duty of the director to the corporation under circumstances in which the
director was aware that his conduct or omission created an unjustifiable risk
of serious injury to the corporation, (iv) constitute a sustained and
unexcused pattern of inattention that amounted to an abdication of the
director's duty to the corporation, or (v) create liability under section 33-
757. Furthermore, section 33-771 generally gives a corporation a right to
indemnify a director if (1) he acted in good faith; and (2) he reasonably
believed his conduct, when acting in his official capacity, was in the best
interest of the corporation and that his conduct, other than in an official
capacity, was not opposed to the best interest of the corporation; and (3) in
the case of a criminal proceeding, he had no reasonable cause to believe his
conduct was unlawful. Section 33-772 states that a corporation must indemnify
a director who was wholly successful, on the merits or otherwise in the
defense of any action or proceeding to which he was a party because he was of
director. Finally, section 33-776 states that a corporation may indemnify and
advance expenses to an officer who is party to a proceeding because he is an
officer to the same extent as a director, or to such further extent consistent
with public policy as provided in the certificate of incorporation, bylaws or
by contract.
 
  The certificate of incorporation of On Demand provides that the personal
liability of a director to On Demand or its stockholders for any monetary
damages for breach of duty as a director shall be limited to an amount that is
equal to the compensation received by the director for serving On Demand
during the year of the violation, if such breach did not (i) involve a knowing
and culpable violation or law by the director, (ii) enable the director or an
associate, as defined in subdivision (3) of section 33-374d of the Act, to
receive an improper personal economic gain, (iii) show a lack of good faith
and a conscious disregard for the duty of the director to On Demand under
circumstances in which the director was aware that his conduct or omission
created an unjustifiable risk of serious injury to the corporation, (iv)
constitute a sustained and unexcused pattern of inattention that amounted to
an abdication of the director's duty to the corporation or (v) create a
liability under section 33-321 of the Act. In general, the bylaws of On Demand
state that the On Demand shall be bound by and comply with the provisions the
CBCA pertaining to indemnification of officers and directors.
 
  The articles of incorporation and the bylaws of Expocon are silent on the
topic of director and officer indemnification.
 
  Technology Events Company, LLC ("Technology Events") is a Connecticut
limited liability company. Section 34-143 of the Connecticut Limited Liability
Corporation Act ("the CLLC") provides that the operating agreement of a
limited liability corporation may: (1) eliminate or limit the personal
liability of a member or manager for monetary damages for breach of any duty
provided for in Section 34-141 of the CLLC; and (2) provide for
indemnification of a member or manager for judgments, settlements, penalties,
fines or expenses incurred in a proceeding to which an individual is a party
because such individual is or was a member or manager. The articles of
organization of Technology Events are silent on the topic of director and
officer indemnification.
 
  Reference is made to each Registrant's charter and bylaws, filed herewith.

ITEM 22. UNDERTAKINGS
 
(a)  The undersigned registrant hereby undertakes:
 
   1.  To file, during any period in which offers or sales 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 the
          information set forth in the registration statement.
          Notwithstanding the foregoing, any increase
 
                                      II-5
<PAGE>
 
         or decrease in 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 or high end 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% change in the maximum aggregate offering price set
         forth in the "Calculation of Registration Fee" table in the
         effective registration statement.
 
      iii.  To include any material information with respect to the plan of
            distribution not previously disclosed in the registration
            statement or any material change to 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.
 
(b) 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 or 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.
 
(c) The undersigned registrant hereby undertakes 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 becomes effective.

          to the provisions of the Business Corporation Law, this Certificate of
          Incorporation, and any By-Laws adopted by the stockholders; provided,
          however, that no By-Laws hereafter adopted by the stockholders shall
          invalidate any prior act of the directors which would have been valid
          if such By-Laws had not been adopted.

          (5)  Any Member of the Board of Directors may be removed, with or
          without cause, at any time prior to the expiration of his term by a
          majority vote of the outstanding shares.

and stated in the notice or waiver of notice of the meeting.

any purpose or purposes, may be called at any time by resolution of the Board of
Directors (or by any officer designated by the Board) and shall be so called

vote at such meeting.  Special meetings of shareholders shall be held at such
place, within or without the State of New York, as shall be fixed by the Board
of Directors (or such designated officer) and stated in the notice or waiver of

not less than 50% of all shares entitled to vote at such meeting, may be

     ------------   ----------------------------------                        
are required or permitted to take any action at a meeting, a written notice
thereof shall state the place, date and hour of the meeting, and, unless it is
the annual meeting, shall indicate that it is being issued by or at the
direction of the Board of Directors (or officer designated by the Board to call
the meeting).  A notice of a special meeting shall also state the purpose or
purposes for which the meeting is called.  A copy of the notice of any meeting
shall be given either personally, by telegraph or by mail, not less than ten nor
more than fifty days before the date of the meeting, to each shareholder
entitled to vote at such meeting.  If mailed, such notice shall be deemed to be
given when deposited in the United States mail, with postage thereon prepaid,
directed to the shareholder at his address as it appears on the record of
shareholders, or, if he shall have filed with the Secretary of the Corporation a
written request that notices to him be mailed to some other address, then
directed to him at such other address.

     When a meeting is adjourned to another time or place, it shall not be
necessary to give any notice of the adjourned meeting if the time and place to
which the meeting is adjourned are announced at the meeting at which the
adjournment is taken; however, if after the adjournment the Board fixes a new
record date for the adjourned meeting, a notice of the adjourned meeting shall
be given to each shareholder of record on the new record date entitled to notice

whether before or after the 
<PAGE>
 
                                      -3-

meeting. The attendance of any shareholder at a meeting, in person or by proxy,
without protesting prior to the conclusion of the meeting the lack of notice of
such meeting, shall constitute a waiver of notice by him.

     Section 1.05.  Quorum.  The holders of a majority of the shares entitled to
     ------------   ------                                                      
vote thereat, present in person or by proxy, shall constitute a quorum at a
meeting of shareholders for the transaction of any business, provided that when
a specified item of business is required to be voted on by a class or series,
voting as a class, the holders of a majority of the shares of such class or
series, present in person or by proxy, shall constitute a quorum for the
transaction of such specified item of business.

     When a quorum is once present to organize a meeting, it shall not be broken
by the subsequent withdrawal of any shareholders.

     The shareholders present in person or by proxy may adjourn the meeting
despite the absence of a quorum and at any such adjourned meeting at which the
requisite holders of shares shall be present, in person or by proxy, any
business may be transacted which might have been transacted at the meeting as
originally noticed.

     Section 1.06.  Fixing Record Date.  For the purpose of determining the
     ------------   ------------------                                     
shareholders entitled to notice of or to vote at any meeting of shareholders or
any adjournment thereof, or to express consent to or dissent from any proposal
without a meeting, or for the purpose of determining shareholders entitled to
receive payment of any dividend or the allotment of any rights, or for the
purpose of any other action, the Board may fix, in advance, a date as the record
date for any such determination of shareholders.  Such date shall not be more
than fifty nor less than ten days before the date of such meeting, nor more than

     ------------   --------------------------------                         
of the record date, certified by the corporate officer responsible for its
preparation or by a transfer agent, shall be produced at any meeting of
shareholders upon the request thereat or prior thereto of any shareholder. If
the right to vote at any meeting is challenged, the inspectors of election, or
person presiding thereat, shall require such list of shareholders to be produced
as evidence of the right of the persons challenged to vote at such meeting, and
all persons who appear from such list to be shareholders entitled to vote
thereat may vote at such meeting.

     Section 1.08.  Proxies.  Every shareholder entitled to vote at a meeting of
     ------------   -------                                                     
shareholders or to express consent or dissent without a meeting may authorize
another person or persons to act for him by proxy.

     Every proxy must be signed by the shareholder or his attorney-in-fact.  No
proxy shall be valid after the expiration of eleven months from the date thereof
unless otherwise provided in the proxy.  Every proxy shall be revocable at the
pleasure of the shareholder executing it except as otherwise provided in Section
609 of the Business Corporation Law.

     Section 1.09.  Selection and Duties of Inspectors.  The Board may appoint
     ------------   ----------------------------------                        
in advance of any shareholders' meeting one or more inspectors to act at the
meeting or any adjournment thereof.  If inspectors are not so appointed, the
person presiding at a shareholders' meeting may, and on the request of any
shareholder entitled to vote thereat shall appoint one or more inspectors.  In
case any person appointed fails to appear or act, the vacancy may be filled by
appointment made by the Board in advance of the meeting or at the meeting by the
person presiding thereat.  Each inspector, before entering upon the discharge of
his duties, shall take and sign an oath faithfully to execute the duties of
inspector at such meeting with strict impartiality and according to the best of
his ability.
<PAGE>
 
                                      -5-

     The inspectors shall determine the number of shares outstanding and the
voting power of each, the shares represented at the meeting, the existence of a
quorum, the validity and effect of proxies, and shall receive votes, ballots or
consents, hear and determine all challenges and questions arising in connection
with the right to vote, count and tabulate all votes, ballots or consents,
determine the result, and do such acts as are proper to conduct the election or
vote with fairness to all shareholders.  On request of the person presiding at
the meeting or any shareholder entitled to vote thereat, the inspectors shall
make a report in writing of any challenge, question or matter determined by them
and execute a certificate of any fact found by them.  Any report or certificate
made by them shall be prima facie evidence of the facts stated and of the vote
as certified by them.

     Unless appointed by the Board or the person presiding at the meeting, as
above provided in this section, inspectors shall be dispensed with at all
meetings of shareholders.

     Section 1.10.  Qualification of Voters.  Except as otherwise provided by
     ------------   -----------------------                                  
the Certificate of Incorporation of the Corporation, every shareholder shall be
entitled at every meeting of shareholders to one vote for every share standing
in his name on the record of shareholders.

     Treasury shares and shares of the Corporation held by any majority-owned
domestic or foreign subsidiary of the Corporation shall not be shares entitled
to vote or to be counted in determining the total number of outstanding shares.

     Shares held by an administrator, executor, guardian, conservator,
committee, or other fiduciary, except a trustee, may be voted by him, either in
person or by proxy, without transfer of such shares into his name.  Shares held
by a trustee may be voted by him, either in person or by proxy, only after the
shares have been transferred into his name as trustee or into the name of his
nominee.

     ------------   --------------------                                 
plurality of the votes cast at a meeting of shareholders by the holders of
shares entitled to vote in the election.  Whenever any corporate action, other
than the election of directors, is to be taken by vote of the shareholders, it
shall, except as otherwise required by the Business Corporation Law or by the
Certificate of Incorporation of the Corporation in conformity with the Business
Corporation Law, be authorized by a majority of the votes cast at a meeting of
shareholders by the holders of shares entitled to vote thereon.

     The vote upon any question at any shareholders' meeting need not be by
ballot.

     Section 1.12.  Action Without a Meeting.  Whenever shareholders are
     ------------   ------------------------                            
required or permitted to take any action by vote, such action may be taken
without a meeting on written consent, setting forth the action so taken, signed
by the holders of all issued and outstanding shares entitled to vote thereon.
This paragraph shall not be construed to alter or modify the provisions of any
section of the Business Corporation Law or any provision in the Certificate of
Incorporation of the Corporation not inconsistent with the Business Corporation
Law under which the written consent of the holders of less than all outstanding
shares is sufficient for corporate action.

     Written consent thus given by the holders of all outstanding shares
entitled to vote shall have the same effect as a unanimous vote of shareholders.

               transaction is approved by vote of the shareholders; or

          (c)  The contract or transaction is fair and reasonable as to the
               Corporation at the time it is approved by the Board, a committee
               or the shareholders.

     ------------   ------------------                                  
Corporation to any director unless it is authorized by vote of the shareholders.
For this purpose, the shares of the director who would be the borrower shall not
be shares entitled to vote.  A loan made in violation of this section shall be a
violation of the duty to the Corporation of the directors approving it, but the
obligation of the borrower with respect to the loan shall not be affected
thereby.

time determine.  Any person may hold two or more offices at the same time,
except (subject to the next sentence) the offices of President and Secretary or,
additionally if there be a Chairman of the Board, the offices of Chairman of the
Board and Secretary.  When all of the issued and outstanding stock of the
Corporation is owned by one person, such person may hold all or any combination
of offices.  The officers of the Corporation may, but need not, be shareholders
of the Corporation nor, except in the case of the Chairman of the Board of
Directors, need such officers be directors of the Corporation.

     Section 3.02.  Term.  Subject to the provisions of Section 3.03 hereof, all

be removed by the Board with or without cause.  The removal of an officer
without cause shall be without prejudice to his contract rights, if any;
however, the election or appointment of an officer shall not of itself create
contract rights.

     Section 3.04.  General Authority.  The officers shall have such authority,
     ------------   -----------------

on behalf of the Corporation, take all such action as any such officer may deem
advisable to vote in person or by proxy at any meeting of security holders of
any corporation in which the Corporation may own securities and at any such
meeting shall possess and may exercise any and all rights and powers incident to
the ownership of such securities and which, as the owner thereof, the
Corporation might have exercised and possessed if present.  The Board may, by
resolution, from time to time confer like powers upon any other person or
persons.

     Section 3.06.  Chairman of the Board of Directors.  The Chairman of the
     ------------   ----------------------------------

the Board of Directors designates the President as the Chief Executive Officer,
and except where by law the signature of the President is required, the Chairman
of the Board of Directors shall possess the same power as the President to sign
all contracts, certificates and other instruments of the Corporation which may
be authorized by the Board of Directors. During the absence or disability of the
President, the Chairman of the Board of Directors shall exercise all the powers
and discharge all the duties of the President. The Chairman of the Board of
Directors shall also perform such other duties and may exercise such other
powers as from time to time may be assigned to him by these By-Laws or by the

the Board of Directors and, if there be one, the Chairman of the Board of
Directors, have general supervision of the business of the Corporation and shall
see that all orders and resolutions of the Board of Directors are carried into
effect.  He shall execute all bonds, mortgages, contracts and other instruments
of the Corporation requiring a seal, under the seal of the Corporation, except
where required or permitted by law to be otherwise signed and executed and
except that the other officers of the Corporation may sign and execute documents
when so authorized by these By-Laws, the Board of Directors or the President.
In the absence or disability of the Chairman of the Board of Directors, or if
there be none, the President shall preside at all meetings of the shareholders
and the Board of Directors.  If there be no Chairman of the Board of Directors,
or if the Board of Directors designates the President as Chief Executive Officer
of the Corporation, the President shall be the Chief Executive Officer of the
Corporation.  The President shall also perform such other duties and may
exercise such other powers as from time to time may be assigned to him by these
By-Laws or by the Board of Directors.

required.  The Secretary shall give, or cause to be given, notice of all
meetings of the shareholders and special meetings of the Board of Directors, and

or President, under whose supervision he shall be.  If the Secretary shall be

shareholders and special meetings of the Board of Directors, and if there be no
Assistant Secretary, then the Board of Directors, the Chairman of the Board, if
there be one, or the President may choose another officer to cause such notice

represented by certificates signed by the President or a Vice-President and the
Secretary or an Assistant Secretary or the Treasurer or an Assistant Treasurer
of the Corporation, and may be sealed with the seal of the Corporation or a
facsimile thereof.  The signatures of the officers upon a certificate may be
facsimiles if the certificate is countersigned by a transfer agent or registered
by a registrar other than the Corporation itself or its employee.  If any
officer who has signed or whose facsimile signature has been placed upon a
certificate shall have ceased to be such officer before such certificate is
issued, it may be issued by the Corporation with the same effect as if he were
such officer at the date of issue.

     Each certificate representing shares shall also set forth such additional
material as is required by subdivisions (b) and (c) of Section 508 of the
Business Corporation Law.

     Section 4.02.  Transfers.  Stock of the Corporation shall be transferable
     ------------   ---------

Laws.  Transfers of stock shall

certificate or by attorney lawfully constituted in writing and upon the
surrender of the certificate therefor, which shall be cancelled before a new
certificate or certificates shall be issued.

     Section 4.03.  Registered Holders.  The Corporation shall be entitled to
     ------------   ------------------                                       
treat and shall be protected in treating the persons in whose names shares or

holders, rights holders or option holders, as the case may be, as the owners
thereof for all purposes and shall not be bound to recognize any equitable or

thereof, except as expressly provided otherwise by these By-Laws and the laws of
the State of New York.

certificate of stock in the place of any certificate theretofore issued by it,
alleged to have been lost, stolen or destroyed, and the directors may, in their
discretion, require the owner of the lost, stolen or destroyed certificate, or
his legal representative, to give the Corporation a bond sufficient (in the
judgment of the directors) to indemnify the Corporation against any claim that
may be made against it on account of the alleged loss or theft or destruction of
any such certificate or the issuance of such new certificate.  A new certificate
may be issued without requiring any bond when, in the judgment of the directors,
it is proper so to do.

     ------------   ---------                                                  
make other distributions in cash or its bonds or its property, including the
shares or bonds of other corporations, on its outstanding shares, except when
currently the Corporation is insolvent or would thereby be made insolvent, or
when the declaration, payment or distribution would be contrary to any
restrictions contained in the Certificate of Incorporation of the Corporation.
<PAGE>
 
                                      -19-

Dividends may be declared or paid and other distributions may be made out of
surplus only, so that the net assets of the Corporation remaining after such
declaration, payment or distribution shall at least equal the amount of its
stated capital.  When any dividend is paid or any other distribution is made, in
whole or in part, from sources other than earned surplus, it shall be
accompanied by a written notice (a) disclosing the amounts by which such
dividend or distribution affects stated capital, capital surplus and earned
surplus, or (b) if such amounts are not determinable at the time of such notice,
disclosing the approximate effect of such dividend or distribution upon stated
capital, capital surplus and earned surplus and stating that such amounts are
not yet determinable.

shareholders or, if practicable, in the first notice of dividend or share
distribution that is furnished to the holders of each class or series of its

or, if practicable, in the first notice of dividend or share distribution that

               Duties of Directors and Officers; Indemnification
               -------------------------------------------------

     Section 6.01.  Duties of Directors.  A director shall perform his duties as
     ------------   -------------------                                         
a director, including his duties as a member of any committee of the Board upon
which he may serve, in good faith and with that degree of care which an
ordinarily prudent person in a like position would use under similar
circumstances.  In performing his duties, a director shall be entitled to rely
on information, opinions, reports or statements including financial statements
and other financial data, in each case prepared or presented by:

          (1)  one or more officers or employees (i) of the Corporation or (ii)
     of any other corporation of which at least fifty percentum of the
     outstanding shares of stock entitling the holders thereof to vote for the
     election of directors is owned directly or indirectly by the Corporation or
     (iii) of any other corporation of any type or kind, domestic or foreign, or
     of any partnership, joint venture, trust, employee benefit plan or other
     enterprise which such director has served in any capacity at the request of
     the Corporation, whom the director believes to be reliable and competent in
     the matters presented, or

          (2)  counsel, public accountants or other persons as to matters which
     the director believes to be within such person's professional or expert
     competence, or
<PAGE>
 
                                      -21-

          (3)  a committee of the Board upon which he does not serve, duly
     designated in accordance with a provision of the Certificate of
     Incorporation or the By-Laws, as to matters within its designated
     authority, which committee the director believes to merit confidence.

so long as in so relying he shall be acting in good faith and with such degree
of care, but he shall not be considered to be acting in good faith if he has
knowledge concerning the matter in question that would cause such reliance to be
unwarranted.  A person who so performs his duties shall have no liability by
reason of being or having been a director of the Corporation.

     Section 6.02.  Duties of Officers.  An officer shall perform his duties as
     ------------   ------------------                                         
an officer in good faith and with that degree of care which an ordinarily
prudent person in a like position would use under similar circumstances.  In
performing his duties, an officer shall be entitled to rely on information,
opinions, reports or statements including financial statements and other
financial data, in each case prepared or presented by:

          (1)  one or more other officers or employees (i) of the Corporation or
     (ii) of any other corporation of which at least fifty percentum of the
     outstanding shares of stock entitling the holders thereof to vote for the
     election of directors is owned directly or indirectly by the Corporation or
     (iii) of any other corporation of any type or kind, domestic or foreign, or
     of any partnership, joint venture, trust, employee benefit plan or other
     enterprise which such officer has served in any capacity at the request of
     the Corporation, whom the officer believes to be reliable and competent in
     the matters presented, or

          (2)  counsel, public accountants or other persons as to matters which
     the officer believes to be within such person's professional or expert
     competence, so long as 
<PAGE>
 
                                      -22-

     in so relying he shall be acting in good faith and with such degree of
     care, but he shall not be considered to be acting in good faith if he has
     knowledge concerning the matter in question that would cause such reliance
     to be unwarranted. A person who so performs his duties shall have no
     liability by reason of being or having been an officer of the Corporation.

     Section 6.03.  Indemnification of Directors, Officers, Employees and Agents
     ------------   ------------------------------------------------------------
in Actions by or in the Right of the Corporation.
- ------------------------------------------------ 

     (a)  Subject to Section 6.05, the Corporation shall indemnify any person,
made a party to an action by or in the right of the Corporation to procure a
judgment in its favor by reason of the fact that he, his testator or intestate,
is or was a director, officer, employee or agent of the Corporation, against the
reasonable expenses, including attorneys' fees, actually and necessarily
incurred by him in connection with the defense of such action, or in connection
with an appeal therein, except in relation to matters as to which a director or
officer is adjudged to have breached his duty to the Corporation under Section
6.01 or under Section 6.02, as the case may be, or in which an employee or agent
is adjudged to have breached his duty to the Corporation, as that duty may from
time to time be defined.

     (b)  The indemnification authorized under paragraph (a) shall in no case
include:

          (1)  amounts paid in settling or otherwise disposing of a threatened
     action, or a pending action with or without court approval, or

          (2)  expenses incurred in defending a threatened action, or a pending
     action which is settled or otherwise disposed of without court approval.

made, or threatened to be made, a party to an action or proceeding other than
one by or in the right of the Corporation to procure a judgment in its favor,
whether civil or criminal, including an action by or in the right of any other
corporation of any type or kind, domestic or foreign, of any partnership, joint
venture, trust, employee benefit plan or other enterprise, which any director,
officer, employee or agent of the Corporation served in any capacity at the
request of the Corporation, by reason of the fact that he, his testator or
intestate, was a director, officer, employee or agent of the Corporation, or
served such other corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise in any capacity, against judgments, fines,
amounts paid in settlement and reasonable expenses, including attorneys' fees
actually and necessarily incurred as a result of such action or proceeding, or
any appeal therein, if such director, officer, employee or agent of the
Corporation acted, in good faith, for a purpose which he reasonably believed to
be in, or, in the case of service for any other corporation or any partnership,
joint venture, trust, employee benefit plan or other enterprise, not opposed to,
the best interests of the Corporation and, in criminal actions or proceedings,
in addition, had no reasonable cause to believe that his conduct was unlawful.

     (b)  The termination of any such civil or criminal action or proceeding by
judgment, settlement, conviction or upon a plea of nolo contendere, or its

officer, employee or agent of the Corporation did not act, in good faith, for a
purpose which he reasonably believed to be in, or, in the case of service for
any other corporation or any partnership, joint venture, trust, employee benefit
plan or other enterprise, not opposed to, the best interests of the Corporation
or that he had reasonable cause to believe that his conduct was unlawful.

     (c)  For the purpose of this Section, the Corporation shall be deemed to
have requested a person to serve an employee benefit plan where the performance
by such person of his duties to the Corporation also imposes duties on, or
otherwise involves services by, such person to the plan or participants or
beneficiaries of the plan; excise taxes assessed on a person with respect to an
employee benefit plan pursuant to applicable law shall be considered fines; and
action taken or omitted by a person with respect to an employee benefit plan in
the performance of such person's duties for a purpose reasonably believed by
such person to be in the interest of the participants and beneficiaries of the
plan shall be deemed to be for a purpose which is not opposed to the best
interests of the Corporation.

     Section 6.05.  Payment of Indemnification Other than by Court Award.
     ------------   ---------------------------------------------------- 

     (a)  A person who has been wholly successful, on the merits or otherwise,
in the defense of a civil or criminal action or proceeding of the character
described in Section 6.03 or 6.04 shall be entitled to indemnification as
authorized in such sections.

     (b)  Except as provided in paragraph (a), any indemnification under Section
6.03 or 6.04 unless ordered by a court under Section 725 of the Business
Corporation Law of New York, shall be made by the Corporation, only if
authorized in the specific case:

          (1)  by the Board acting by a quorum consisting of directors who are
     not parties to such action or proceeding upon a finding that the director,
     officer, employee or agent has met the standard of conduct set forth in
     Section 6.03 or 6.04, as the case may be, or,

          (2)  if a quorum under subparagraph (1) is not obtainable with due
     diligence:

               (A)  by the Board upon the opinion in writing of independent
          legal counsel that indemnification is proper in the circumstances
          because the applicable 
<PAGE>
 
                                      -25-

          standard of conduct set forth in such sections has been met by such
          director, officer, employee or agent, or

               (B)  by the shareholders upon a finding that the director,
          officer, employee or agent has met the applicable standard of conduct
          set forth in such sections.

     It is the policy of the Corporation that indemnification of the persons
specified in Sections 6.03 and 6.04 shall be made to the fullest extent
permitted by law.

     (c)  Expenses incurred in defending a civil or criminal action or
proceeding may be paid by the Corporation in advance of the final disposition of
such action or proceeding if authorized under paragraph (b).

     Section 6.06.  Other Provisions Affecting Indemnification of Directors,
     ------------   --------------------------------------------------------
Officers, Employees and Agents.
- ------------------------------ 

     (a)  All expenses incurred in defending a civil or criminal action or
proceeding which are advanced by the Corporation under paragraph (c) of Section
6.05 or allowed by a court shall be repaid in case the person receiving such
advancement or allowance is ultimately found, under the procedure set forth in
this Article VI or in Section 725 of the New York Business Corporation Law, not
to be entitled to indemnification or, where indemnification is granted, to the
extent the expenses so advanced by the Corporation or allowed by the court
exceed the indemnification to which he is entitled.

     (b)  No indemnification, advancement or allowance shall be made under this
Article VI in any circumstance where it appears:

          (1)  that the indemnification would be inconsistent with a provision
     of the Certificate of Incorporation, a By-Law, a resolution of the Board or
     of the shareholders, 
<PAGE>
 
                                      -26-

     an agreement or other proper corporate action, in effect at the time of the
     accrual of the alleged cause of action asserted in the threatened or
     pending action or proceeding in which the expenses were incurred or other
     amounts were paid, which prohibits or otherwise limits indemnification; or

          (2)  if there has been a settlement approved by the court, that the
     indemnification would be inconsistent with any condition with respect to
     indemnification expressly imposed by the court in approving the settlement.

     (c)  If, under this Article VI, any expenses or other amounts are paid by
way of indemnification, otherwise than by court order or action by the
shareholders, the Corporation shall, not later than the next annual meeting of
shareholders unless such meeting is held within three months from the date of
such payment, and, in any event, within fifteen months from the date of such
payment, mail to its shareholders of record at the time entitled to vote for the
election of directors a statement specifying the persons paid, the amounts paid,
and the nature and status at the time of such payment of the litigation or
threatened litigation.

     Section 6.07.  Non-Exclusivity and Survival of Indemnification.  The
     ------------   -----------------------------------------------      
provisions of this Article VI shall not be deemed to preclude the
indemnification of any person who is not specified in Section 6.03 or 6.04 but
whom the Corporation has the power or obligation to indemnify under the
provisions of the Business Corporation Law of New York, or otherwise.  The
indemnification provided by this Article VI shall continue as to a person who
has ceased to be a director, officer, employee or agent and shall inure to the
benefit of the heirs, executors, and administrators of such person.  The
indemnification provided by this Article VI shall not be deemed exclusive of any
other right to which employees or agents (other than officers or directors) of
the Corporation seeking indemnification may be entitled under any By-Law,
<PAGE>
 
                                      -27-

agreement, contract, vote of shareholders or disinterested directors or pursuant
to the direction (howsoever embodied) of any court of competent jurisdiction or
otherwise, both as to actions in their official capacity and as to actions in
another capacity while serving the Corporation.

     Section 6.08.  Insurance for Indemnification of Directors, Officers,
     ------------   -----------------------------------------------------
Employees and Agents.
- -------------------- 

     (a)  Subject to paragraph (b) below, the Corporation shall have the power
to purchase and maintain insurance:

          (1)  to indemnify the Corporation for any obligation which it incurs
     as a result of the indemnification of directors, officers, employees and
     agents under the provisions of this Article VI, and

          (2)  to indemnify directors, officers, employees and agents in
     instances in which they may be indemnified by the Corporation under the
     provisions of this Article VI, and

          (3)  to indemnify directors, officers and employees and agents in
     instances in which they may not otherwise be indemnified by the Corporation
     under the provisions of this Article VI provided the contract of insurance
     covering such directors, officers employees and agents provides, in a
     manner acceptable to the superintendent of insurance, for a retention
     amount and for co-insurance.

     (b)  No insurance under paragraph (a) may provide for any payment, other
than cost of defense, to or on behalf of any director, officer or employee or
agent:
          (1)  if a judgment or other final adjudication adverse to the insured
     director, officer, employee or agent establishes that his acts of active
     and deliberate dishonesty 
<PAGE>
 
                                      -28-

     were material to the cause of action so adjudicated, or that he personally
     gained in fact a financial profit or other advantage to which he was not
     legally entitled, or

          (2)  in relation to any risk the insurance of which is prohibited
     under the insurance law of the State of New York.

     (c)  Insurance under any or all subparagraphs of paragraph (a) may be
included in a single contract or supplement thereto.  Retrospective rated
contracts are prohibited.

     (d)  The Corporation shall, within the time and to the persons provided in
paragraph (c) of Section 6.06, mail a statement in respect of any insurance it
has purchased or renewed under this Section, specifying the insurance carrier,
date of the contract, cost of the insurance, corporate positions insured, and a
statement explaining all sums, not previously reported in a statement to
shareholders, paid under any indemnification insurance contract.

     Section 6.09.  Meaning of "Corporation" for Purposes of Article VI.  For
     ------------   ---------------------------------------------------      
purposes of this Article VI, references to "the Corporation" shall include, in
addition to the resulting corporation, any constituent corporation (including
any constituent of a constituent) absorbed in a consolidation or merger which,
if its separate existence had continued, would have had power and authority to
indemnify its directors, officers, employees or agents so that any person who is
or was a director, officer, employee or agent of such constituent corporation,
or is or was serving at the request of such constituent corporation as a
director, officer, employee or agent of another corporation of any type or kind,
domestic or foreign, partnership, joint venture, trust, employee benefit plan or
other enterprise, shall stand in the same position under the provisions of this
Article VI with respect to the resulting or surviving corporation as he would
have with respect to such constituent corporation if its separate existence had
continued.

successors or assigns, the Merged Corporation will execute and deliver or cause
to be executed and delivered all such deeds and instruments and will take or
cause to be taken all such further action that the Surviving Corporation may

purposes hereof, and the officers and directors of the Merged Corporation and

          (e) This Agreement shall not be submitted to the stockholders of each
of the Constituent Corporations as permitted by law and specifically by Section

of Holdings, its stockholders, Board of Directors, committees elected or
appointed by the Board of Directors, officers and agents, which were valid and
effective immediately prior to the effective time of the merger, shall be taken
for all purposes as the acts, plans, policies, approvals and authorizations of
the Surviving Corporation and shall be effective and binding thereon as they
were on Holdings.  The employees of Holdings shall become the employees of the
Surviving Corporation and continue to be entitled to the same rights and
benefits they enjoyed as employees of Holdings.

          (h) From the effective time of the merger, the officers and directors
of the Surviving Corporation are hereby authorized in the name of the
corporations that were the Constituent Corporations to execute, acknowledge and
deliver all instruments and do all things as may be necessary or desirable to
vest in the Surviving Corporation any property or rights of either of the
Constituent Corporations or to carry out the purposes of this Agreement.

determination shall apply to any adjournment thereof, unless the Board fixes a
new record date for the adjourned meeting.

     2.6  Notice of Meetings of Stockholders. Except as otherwise provided in
          ----------------------------------                                 
Sections 2.5 and 2.7 of the By-laws, whenever under the General Corporation Law
or the Certificate of Incorporation or the By-laws, stockholders are required or
permitted to take any action at a meeting, written notice shall be given stating
the place, date and hour of the meeting and, in the case of a special meeting,
the purpose or purposes for which the meeting is called.  A copy of the notice
of any meeting shall be given, personally or by mail, not less than ten nor more
than sixty days before the date of the-meeting, to each stockholder entitled to
notice of or to vote at such meeting.  If mailed, such notice shall be deemed to
be given when deposited in the United States mail, with postage prepaid,
directed to the stockholder at his address as it appears on the records of the
Corporation.  An affidavit of the Secretary or an Assistant Secretary or of the
transfer agent of the Corporation that the notice required by this section has
been given shall, in the absence of fraud, be prima facie evidence of the facts
stated therein.  When a meeting is adjourned to another time or place, notice
need not be given of the adjourned meeting if the time and place thereof are
announced at the meeting at which the adjournment is taken, and at the adjourned
meeting any business may be transacted that might have been transacted at the
meeting as originally called.  If, however, the adjournment is for more than
thirty days, or if after

          -----------------                                                 
stockholder under any provision of the General Corporation Law or the
Certificate of Incorporation or the By-laws, a written waiver thereof, signed by
the stockholder entitled to notice, whether before or after the time stated
therein, shall be deemed equivalent to notice.  Attendance of a stockholder at a
meeting shall constitute a waiver of notice of such meeting, except when the
stockholder attends a meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened.  Neither the business to be transacted at,
nor the purpose of, any regular or special meeting of the stockholders need be
specified in any written waiver of notice.

     2.8  List of Stockholders.  The Secretary shall prepare and make, or cause
          --------------------                                                 
to be prepared and made, at least ten days before every meeting of stockholders,
a complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  Such list shall be open
to the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held.

     The list shall also be produced and kept at the time and place of the
meeting during the whole time thereof, and may be inspected by any stockholder
who is present.

     2.9  Quorum of Stockholders; Adjournment.  The holders of one-third of the
          -----------------------------------                                  
shares of stock entitled to vote at any meeting of stockholders, present in
person or represented by proxy, 

                                      -5-
<PAGE>
 
shall constitute a quorum for the transaction of any business at such meeting.
When a quorum is once present to organize a meeting of stockholders, it is not
broken by the subsequent withdrawal of any stockholders. The holders of a
majority of the shares of stock present in person or represented by proxy at any
meeting of stockholders, including an adjourned meeting, whether or not a quorum
is present, may adjourn such meeting to another time and place.

     2.10  Voting; Proxies.  Unless otherwise provided in the Certificate of
           ---------------                                                  
Incorporation every stockholder of record shall be entitled at every meeting of
stockholders to one vote for each share of capital stock standing in his name on
the record of stockholders determined in accordance with Section 2.5 of the By-
laws.  If the Certificate of Incorporation provides for more or less than one
vote for any share, on any matter, every reference in the By-laws or the General
Corporation Law to a majority or other proportion of stock shall refer to such
majority or other proportion of the votes of such stock.  The provisions of
Sections 212 and 217 of the General Corporation Law shall apply in determining
whether any shares of capital stock may be voted and the persons, if any,
entitled to vote such shares; but the Corporation shall be protected in treating
the persons in whose names shares of capital stock stand on the record of
stockholders as owners thereof for all purposes.  At any meeting of stockholders
(at which a quorum was present to organize the meeting), all matters, except as
otherwise provided by law or by the Certificate of Incorporation or by the By-
laws, shall be decided by a majority of the votes cast at such meeting by the
holders of shares present in person or represented by proxy and entitled to vote
thereon, whether or not a quorum is present when the vote is taken.  All
elections of directors shall be by written ballot unless otherwise provided in
the Certificate of Incorporation.  In voting on any other question on which a
vote by ballot is required by law or is demanded by any stockholder entitled to
vote, the voting shall be by ballot.  Each ballot shall be signed by the
stockholder 

                                      -6-
<PAGE>
 
voting or by his proxy, and shall state the number of shares voted. On all other
questions, the voting may be viva voce. Every stockholder entitled to vote at a
                             ---- ----                             
meeting of stockholders or to express consent or dissent to corporate action in
writing without a meeting may authorize another person or persons to act for him
by proxy. The validity and enforceability of any proxy shall be determined in
accordance with Section 212 of the General Corporation Law.

     2.11  Selection and Duties of Inspectors at Meetings of-Stockholders.  The
           --------------------------------------------------------------      
Board, in advance of any meeting of stockholders, may appoint one or more
inspectors to act at the meeting or any adjournment thereof.  If inspectors are
not so appointed, the person presiding at such meeting may, and on the request
of any stockholder entitled to vote thereat shall, appoint one or more
inspectors.  In case any person appointed fails to appear or act, the vacancy
may be filled by appointment made by the Board in advance of the meeting or at
the meeting by the person presiding thereat.  Each inspector, before entering
upon the discharge of his duties, shall take and sign an oath faithfully to
execute the duties of inspector at such meeting with strict impartiality and
according to the best of his ability.  The inspector or inspectors shall
determine the number of shares outstanding and the voting power of each, the
shares represented at the meeting, the existence of a quorum, the validity and
effect of proxies, and shall receive votes, ballots or consents, hear and
determine all challenges and questions arising in connection with the right to
vote, count and tabulate all votes, ballots or consents, determine the result,
and do such acts as are proper to conduct the election or vote with fairness to
all stockholders.  On request of the person presiding at the meeting or any
stockholder entitled to vote thereat, the inspector or inspectors shall make a
report in writing of any challenge, question or matter determined by him or them
and execute a certificate of any fact found by him or them.  Any 

                                      -7-
<PAGE>
 
report or certificate made by the inspector or inspectors shall be prima facie
evidence of the facts stated and of the vote as certified by him or them.

     2.12  Organization.  At every meeting of stockholders, the President, or in
           ------------                                                         
the absence of the President a Vice President, and in case more than one Vice
President shall be present, that Vice President designated by the Board (or in
the absence of any such designation, the most senior Vice President, based on
age, present), shall act as chairman of the meeting.  The Secretary, or in his
absence one of the Assistant Secretaries, shall act as secretary of the meeting.
In case none of the officers above designated to act as chairman or secretary of
the meeting, respectively, shall be present, a chairman or a secretary of the
meeting, as the case may be, shall be chosen by a majority of the votes cast at
such meeting by the holders of shares of capital stock present in person or
represented by proxy and entitled to vote at the meeting.

     2.13  Order of Business.  The order of business at all meetings of
           -----------------                                           
stockholders shall be as determined by the chairman of the meeting, but the
order of business to be followed at any meeting at which a quorum is present may
be changed by a majority of the votes cast at such meeting by the holders of
shares of capital stock present in person or represented by proxy and entitled
to vote at the meeting.

     2.14  Written Consent of Stockholders Without a Meeting.  Unless otherwise
           -------------------------------------------------                   
provided in the Certificate of Incorporation, any action required by the General
Corporation Law to be taken at any annual or special meeting of stockholders of
the Corporation, or any action which may be taken at any annual or special
meeting of such stockholders, may be taken without a meeting, without prior
notice and without a vote, if a consent in writing, setting forth the action so
taken, shall be signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which 

                                      -8-
<PAGE>
 
all shares entitled to vote thereon were present and voted. Prompt notice of the
taking of the corporate action without a meeting by less than unanimous written
consent shall be given to those stockholders who have not consented in writing.

such owner and for all other purposes as respects the Corporation.  No transfer

and its transfer agents and registrars, or such of them as the Board may
require, a bond in such form, in such sums and with such surety or sureties as
the Board may direct, to indemnify the Corporation and its transfer agents and
registrars against any claim that may be made against any of them on account of
the continued existence of any such certificate so alleged to have been lost,

permitted by Section 202 of the General Corporation Law and noted conspicuously
on the certificate representing such capital stock, may be enforced against the
holder of the restricted capital stock or any successor or transferee of the
holder including an executor, administrator, trustee, guardian or other
fiduciary entrusted with like responsibility for the person or estate of the
holder.  Unless noted conspicuously on the certificate representing such capital
stock, a restriction, even though permitted by Section 202 of the General
Corporation Law, shall be ineffective except against a person with actual
knowledge of the restriction.  A restriction on the transfer or registration of
transfer of capital stock of the Corporation may be imposed either by the
Certificate of Incorporation or by an agreement among any number of stockholders
or among such stockholders and the Corporation.  No restriction so imposed shall
be binding with respect to capital stock issued prior to the adoption of the
restriction unless the holders of such capital stock are parties to an agreement
or voted in favor of the restriction.

     of its bonds, debentures, notes, scrip or other securities or evidences of
     indebtedness;

          7.7.3  May set aside from time to time out of such surplus or net
     profits such sum or sums as, in its discretion, it may think proper, as a
     reserve fund to meet contingencies, or for equalizing dividends or for the
     purpose of maintaining or increasing the property or business of the
     Corporation, or for any purpose it may think conducive to the best
     interests of the Corporation.

meeting of shareholders or any adjournment thereof, or shareholders entitled to
receive payment of any dividends, or in order to make a determination of
shareholders for any other proper purpose, the Board of Directors of the
Corporation may provide that the stock transfer books shall be closed for a
stated period but not to exceed, in any case, seventy days.  If the stock
transfer books shall be closed for the purpose of determining shareholders
entitled to notice of or to vote at a meeting of shareholders, such books shall
be closed for at least ten full days immediately preceding such meeting.  In
lieu of closing stock transfer books, the Board of Directors may fix in advance
a date as the record date of any such determination of shareholders, such date
in any case to be not more than seventy days and, in case of a meeting of
shareholders, not less than ten full days prior to the date on which the
particular action requiring such determination of shareholders is to be taken.
If the 
<PAGE>
 
                                      -3-

stock transfer books are not closed and no record date is fixed for a
determination of shareholders entitled to notice of or to vote at a meeting of
shareholders or a determination of shareholders entitled to receive payment of a
dividend, the date on which notice of the meeting is mailed or the date on which
the resolution of the Board of Directors declaring such dividend is adopted, as
the case may be, shall be the record date for determination of shareholders.
When a determination of shareholders entitled to vote at any meeting of
shareholders has been made as provided in this section, such determination shall
apply to any adjournment thereof. A record date, or date for closing the stock
transfer books, is effective as of the close of business on such date unless
another hour is designated by the resolution of the Board of Directors.

     SECTION 7.  Voting Lists.  The officer or agent having charge of the stock
                 ------------                                                  
transfer books for shares of the Corporation shall make a complete list of the
shareholders entitled to vote at each meeting of shareholders or any adjournment
thereof, arranged in alphabetical order with the address of and the number of
shares by each.  Such list or other equivalent record shall, for a period of
five days prior to such meeting, be kept on file at the principal office of the
Corporation or at the office or place of business of a transfer agent in this
state and shall be subject to inspection by any shareholder during usual
business hours for any proper purpose.  Such list or other equivalent record
shall also be produced and kept at the time and place of the meeting and shall
be subject for any such proper purpose to such inspection during the whole time
of the meeting.

     SECTION 8.  Qualification of Voters.  Except as may otherwise be provided
                 -----------------------                                      
in the Certificate of Incorporation, every shareholder of record shall be
entitled at every meeting of shareholders to one vote for every share standing
in his name on the record of shareholders.

     Shares of the Corporation standing in the name of another domestic or
foreign corporation of any type or kind may be voted by such officer, agent or
proxy as the by-laws or similar regulations of such corporation may provide, or
in the absence of such provision, as the Board of Directors of such corporation
may determine.

     Treasury shares shall not be shares entitled to vote or to be counted in
determining the total number of outstanding shares of the Corporation.

     SECTION 9.  Quorum.  At any meeting of the shareholders the presence, in
                 ------                                                      
person or by proxy, of the holders of a majority of the shares entitled to vote
thereat shall constitute a quorum for the transaction of any business except
where a greater number is otherwise provided by law.  When a quorum is once
present to organize a meeting, it is not broken by the subsequent withdrawal of
any shareholders.  A majority of the shareholders present, in person or by
proxy, may adjourn the meeting despite the absence of a quorum.

     SECTION 10. Proxies.  Every shareholder entitled to vote at a meeting of
                 -------                                                     
shareholders, to waive notice of such meeting or to express consent or dissent
without meeting may authorize another person or persons in writing to act for
him by proxy.  Every proxy must be signed by the shareholder or his attorney-in-
fact.  No proxy shall be valid after the expiration of eleven months from the
date thereof unless otherwise provided in the proxy, provided in no event shall
a proxy be valid after ten years from its date of execution.  Every proxy shall
be revocable at the pleasure of the shareholder executing it, except as
otherwise provided therein and as permitted by law.  The attendance at any
meeting by the shareholder who shall have previously given a proxy applicable
thereto shall not, as such, have the effect of revoking the proxy.  The
Corporation may treat any proxy as not revoked and in full force and effect
until it receives a duly executed 
<PAGE>
 
                                      -5-

instrument revoking it or a proxy bearing a later date or, in the event of death
or incapacity of the shareholder executing the same, written notice of such
death or incapacity.

     SECTION 11. Voting.  Directors shall be elected by a plurality of the
                 ------                                                   
votes cast at a meeting of shareholders when a quorum is present by the holders
of shares entitled to vote in the election, in person or by proxy.  Whenever any
corporate action, other than the election of directors, is to be taken by vote
of the shareholders, it shall, except as otherwise require by law, be authorized
by a majority of the votes cast in person or by proxy at a meeting when a quorum
is present.

     SECTION 12. Action Without a Meeting.  Whenever the shareholders are
                 ------------------------                                
required or permitted to take any action by vote, such action may be taken
without a meeting on written consent, setting forth the action so taken, signed
by the holders of all outstanding shares entitled to vote thereon.

nine as may be fixed from time to time by resolution adopted by the shareholders
or by the Board.  In the absence of such resolution, the number of directors

director in office or shorten his term.  When all of the shares are owned by
less than three

any time by giving written notice to the Board of Directors or to the President
or the Secretary of the Corporation.  Such resignation shall take effect at the

     SECTION 5.  Removal of Directors.  Any or all of the directors may be

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

each consisting of two or more directors. The Board of Directors may designate
one or more directors as alternate members of any such committee, who may
replace any absent member or members at any meeting of such committee.

     The designation of such executive committee or other committee shall not
operate to relieve the Board of Directors, or any member thereof, of any
responsibility imposed by law.  The executive committee, when the Board of
Directors is not in session, shall have and may exercise all of the authority of
the Board of Directors except to the extent, if any, that such authority shall
be limited by these By-Laws, by the resolution appointing the executive
committee or by law.  Each such other committee shall have and may exercise such
powers as may be authorized in the resolution appointing such other committee
and permitted by law.  Neither the executive committee nor such other committees
shall have the authority of the Board of Directors with respect to amending the
certificate of incorporation, adopting a plan of merger or consolidation,
recommending to the shareholders a voluntary dissolution of the Corporation or a
revocation thereof, or amending the By-Laws of the Corporation.

     SECTION 8.  Compensation of Directors.  The Board of Directors shall have
                 -------------------------

     A notice, or waiver of notice, need not specify the purpose or purposes of
any special meeting or regular meeting of the Board of Directors.

     SECTION 3.  Quorum; Action by the Board; Adjournment.  At all meetings of

a meeting if all members of the Board of Directors or of the committee consent
in writing to the adoption of a resolution authorizing the action, provided that
the number of directors then in office or serving on such committee and taking
such action shall constitute a quorum for such action.  Such resolution and the
written consent thereto by the members of the Board of Directors or the
committee shall be filed with the minutes of the proceedings of the Board of
Directors or the committee.

     SECTION 5.  Presumption of Assent.  A director of the Corporation who is

action on any corporate matter is taken shall be presumed to have assented to
the action taken unless his dissent shall be entered in the minutes of the
meeting or unless he shall file his written dissent to such action with the
person acting as the secretary of the meeting before the adjournment thereof or

Board of Directors and until his successor has been elected or appointed and
qualified.  Any officer may be removed by the Board of Directors with or without
cause.  The removal of an officer without cause shall be without prejudice to

                              AGREEMENT OF MERGER

     This Agreement of Merger (the "Agreement") is dated as of April 30, 1998,
by and between CIGAM Merger Corp., a California corporation ("Merger Sub") and
Men's Apparel Guild in California, Inc., a California corporation ("MAGIC")
(MAGIC and Merger Sub being hereinafter collectively referred to as the
"Constituent Corporations").

                                   RECITALS

     A.  Merger Sub's authorized stock consists of 1,000 shares of common stock,
no par value per share, all of which shares are issued and outstanding.

     B.  Advanstar Communications Inc., a New York corporation ("Advanstar"), is
the owner of all of the issued and outstanding capital stock of Merger Sub.

     C.  Advanstar, Merger Sub and MAGIC have entered into an Agreement and Plan
of Merger, dated March 6, 1998, as amended (the "Merger Agreement"), which
contemplates the merger of Merger Sub with and into MAGIC (the "Merger") in
accordance with this Agreement.

     D.  The respective Boards of Directors of Merger Sub and MAGIC deem it
advisable and in the best interest of each such corporation and their respective
shareholders that Merger Sub be merged with and into MAGIC as provided herein
and in the Merger Agreement, and they have accordingly adopted resolutions
approving the Merger Agreement and this Agreement.

     E.  Advanstar, as the sole shareholder of Merger Sub, has approved this
Agreement in accordance with the laws of California, and the shareholders of
MAGIC have approved this Agreement in accordance with the laws of California and
the Articles of Incorporation of MAGIC at a special meeting of the shareholders
of MAGIC.

     Capitalized terms not otherwise defined herein shall have the meanings
given them in the Merger Agreement.

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein, the parties hereto agree as follows:

                                   ARTICLE I
                                  THE MERGER

     At the Effective Time (as defined below) and subject to the applicable
provisions of the Corporations code of California ("California Law"), Merger Sub
shall be merged with and into MAGIC, the separate corporate existence of Merger
Sub shall cease, and MAGIC shall continue at the surviving corporation and as a
wholly-owned subsidiary of Advanstar.  MAGIC as the surviving corporation after
the Merger is hereinafter sometimes referred to as the "Surviving Corporation".
At the Effective Time, the effect of the Merger shall be as provided in the
applicable provisions of California Law.  Without limiting the generality of the
foregoing and 
<PAGE>
 
                                      -2-



subject thereto, at the Effective Time, all the property, rights, privileges,
powers and franchises of Merger Sub and MAGIC shall vest in the Surviving
Corporation, and all debts, liabilities and duties of Merger Sub and MAGIC shall
become the debts, liabilities and duties of the Surviving Corporation. If at any
time after the Effective Time any further action is necessary or desirable to
carry out the purposes of this Agreement or to vest the Surviving Corporation
with the full right, title and possession to all assets, property, rights,
privileges, immunities, powers and franchises of Merger Sub, the officers and
directors of the Surviving Corporation are fully authorized in the name of
either or both of the Constituent corporations or otherwise to take all such
action. As of the Effective Time, the Articles of Incorporation of the Surviving
Corporation shall be amended and restated to read as set forth in Exhibit A
                                                                  --------- 
attached hereto.
                

                                  ARTICLE II
                                EFFECTIVE TIME

     As used in this Agreement, the term "Effective Time" shall mean the time
Secretary of State of the State of California files this Agreement and the
officers' certificates required by California Law with the Secretary of State of
the State of California.

                                  ARTICLE III
                     MANNER AND BASIS OF EXCHANGING SHARES

     A.  Exchange Terms of MAGIC Common Stock.  Subject to the terms and
         ------------------------------------                           
conditions of this Agreement, by virtue of the Merger and without any action on
the part of MAGIC or the holder of any shares (the "MAGIC Shareholders") of the
common stock, no par value, of MAGIC (the "MAGIC Common Stock"), each share of
MAGIC Common Stock issued and outstanding immediately prior to the Effective
Time (other than shares in the treasury of MAGIC, all of which shall be
canceled, and Dissenting Shares, as defined below) shall, as of the Effective
Time and pursuant to the Merger Agreement, be canceled and extinguished and be
converted automatically into a right to receive a pro-rata share of $230,200,000
from which they shall pay on a pro-rata basis all costs, fees and expenses of
MAGIC's accountants, investment bankers and lawyers and payments to certain
MAGIC executives and employees, and shall deposit $3,000,000 in escrow (the
"Escrow Fund") in accordance with the Merger Agreement and the Adjustment Escrow
Agreement (the amount remaining after such payments and deposit in escrow is
herein referred to as the "Aggregate merger Consideration").  Each of such
shares of MAGIC Common Stock shall also have the right to receive a pro-rata
share of the Net Worth Surplus, if any, as defined and in accordance with the
Merger Agreement.  Shares of MAGIC Common Stock held by MAGIC Shareholders who
(1) have not voted such shares in favor of the Merger, (2) shall have delivered
a written demand for appraisal of such shares in the manner provided by
California Law and (3) shall not have effectively withdrawn or lost such right
to appraisal as of the Effective Time ("Dissenting Shares") shall not be
converted automatically into a right to receive a pro-rata share of the merger
consideration, but the holders of Dissenting Shares shall be entitled only to
such rights as are granted by California Law.  If a holder of Dissenting Shares
shall withdraw his or her demand for such payment and appraisal or shall become
ineligible for such payment and appraisal under California Law, then, as of the
occurrence of such event of withdrawal or ineligibility, such holder's
Dissenting Shares shall cease to be Dissenting Shares and shall be converted
into the right to receive, and shall be 
<PAGE>
 
                                      -3-

exchangeable for, the merger consideration, without interest thereon, into which
such Dissenting Shares would have been converted pursuant to this paragraph A of
Article III.

     B.  Exchange Procedures
         -------------------

         1.  MAGIC Common Stock.  At or after the Effective Time, each MAGIC
             ------------------                                             
Shareholder shall surrender to the Exchange Agent all certificate(s)
representing shares of MAGIC Common Stock (the "MAGIC Stock Certificates") in
accordance with the requirements of the Merger Agreement, the Exchange Agent
Agreement and the Exchange Agent, if any.  At or immediately prior to the
Effective Time, Advanstar will, or will cause Merger Sub to, deliver (a) the
Aggregate Merger Consideration to the Exchange Agent, who will make appropriate
payments to the MAGIC Shareholders as soon as practicable after the Effective
Time, and (b) the Escrow Fund to the Escrow Agent.  Within five (5) days of the
Determination Date, Advanstar will, or will cause the Surviving Corporation to,
deliver the Net Worth Surplus, if any, and the Escrow Agent will deliver the
amount of the Escrow Fund payable to the MAGIC Shareholders, each to the
Exchange Agent, who will make appropriate payments to the MAGIC Shareholders as
soon as practicable thereafter in accordance with the Exchange Agent Agreement.

         2.  Merger Sub Common Stock. Each share of common stock of the Merger
             -----------------------
Sub issued and outstanding immediately prior to the Effective Time shall, by
virtue of the Merger and without any action on the part of the holder thereof,
be converted into and represent the right to receive one share of common stock
of the Surviving Corporation.

         3.  Transfers. If payment is to be made to a person other than the
             --------- 
person in whose name the surrendered MAGIC Stock Certificate is registered, it
shall be a condition of payment that the MAGIC Stock Certificate so surrendered
shall be properly endorsed or otherwise in proper form for transfer and that the
person requesting such payment shall pay any transfer or other taxes required by
reason of the payment to a person other than the registered holder of the MAGIC
Stock Certificate surrendered or establish to the satisfaction of the Surviving
Corporation that such tax has been paid or is not applicable.

         4.  No Liability. Notwithstanding anything to the contrary in this
             ------------  
Article III, neither Advanstar nor any party to this Agreement shall be liable
to the MAGIC Shareholders for any amount of the merger consideration if such
holder fails to present his or her MAGIC Stock Certificate to the Exchange
Agent.

     C.  Instructions to Exchange Agent.  At or prior to the Closing, MAGIC
         ------------------------------                                    
shall deliver to the Exchange Agent instructions, which may be amended from time
to time thereafter (the "MAGIC Instructions"), identifying each of the holders
of MAGIC Common Stock and the portion of the merger consideration that each such
holder is entitled to receive in the Merger.  The Exchange Agent shall be
entitled to rely without investigation on the information set forth in the MAGIC
Instructions in delivering the merger consideration to the MAGIC Shareholders.
Notwithstanding anything to the contrary in this Agreement of Merger, neither
the Exchange Agent nor any successor thereto shall be obligated to deliver any
portion of the merger 
<PAGE>
 
                                      -4-

consideration to the MAGIC Shareholders unless and until MAGIC shall have
delivered the MAGIC Instructions.

     D.  No Further Rights in MAGIC Common Stock.  The Aggregate Merger
         ---------------------------------------                       
Consideration delivered upon the surrender for exchange of shares of MAGIC
Common Stock in accordance with the terms hereof, and the right to receive, in
accordance with the terms of the Exchange Agent Agreement, a share of the Escrow
Fund, if payable, and the Net Worth Surplus, if any, shall be deemed to been
issued in full satisfaction of all rights pertaining to such shares of MAGIC
Common Stock and there shall be no further registration of transfers on the
records of the Surviving Corporation of shares of MAGIC Common Stock which were
outstanding immediately prior to the Effective Time.

     E.  Lost, Stolen or Destroyed MAGIC Stock Certificates.  In the event any
         --------------------------------------------------                   
MAGIC Stock Certificates shall have been lost, stolen or destroyed, the Exchange
Agent shall distribute the appropriate pro-rata share of the merger
consideration to the holder of such MAGIC Stock Certificate only upon the
making, and delivery to the Exchange Agent, of an affidavit of that fact by such
holder.

                                  ARTICLE IV
                             ABANDONMENT OF MERGER

     This Agreement shall be terminated and abandoned without further action by
the parties hereto in the event that the Merger Agreement is terminated in
accordance with its terms, and in such event this Agreement of Merger shall have
no further force and there shall be no liability on the part of the parties
hereto to each other, except to the extent otherwise provided in the Merger
Agreement.

                                   ARTICLE V
                                   AMENDMENT

     Subject to applicable law, this Agreement may be amended or modified or
supplemented only by written agreement of Merger Sub and MAGIC, duly authorized
by each of their respective Boards of Directors, at any time prior to the filing
of the officers' certificates required by California law with respect to the
Merger with the Secretary of State of the State of California; provided,
however, that no such amendment, modification or supplement shall change the
amount or the form of the consideration to be furnished to the MAGIC
Shareholders in accordance with Article III hereof or change any principle terms
without obtaining shareholder approval as required by law.

                                                                       ---------
 
                             AMENDED AND RESTATED
                           ARTICLES OF INCORPORATION
                                      OF
                    MEN'S APPAREL GUILD IN CALIFORNIA, INC.

                                        
FIRST:    The name of this corporation is Men's Apparel Guild In California,
          Inc.

SECOND:   The Purpose of this corporation is to engage in any lawful act or
          activity for which a corporation may be organized under the General
          Corporation Law of California other than the banking business, the
          trust company business or the practice of a profession permitted to be
          incorporated by the California Corporations Code.

THIRD:    This Corporation is authorized to issue only one class of shares, all
          of which shall be known as Common Stock, without par value. The total
          number of shares which this corporation is authorized to issue is
          1,000.

FOURTH:   The liability of the directors of this corporation for monetary
          damages shall be eliminated to the fullest extent permissible under
          California law. This corporation is also authorized, to the fullest
          extent permissible under California law, to indemnify its agents (as
          defined in Section 317 of the California Corporations Code), whether
          by by-law, agreement or otherwise, for breach of duty to this
          corporation and its shareholders in excess of that expressly permitted
          by Section 317 and to advance defense expenses to its agents in
          connection with such matters as they are incurred, subject to the
          limits on such excess indemnification set forth in Section 204 of the
          California Corporations Code. If, after the effective date of this
          Article, California law is amended in a manner which permits a
          corporation to limit the monetary or other liability of its directors
          or to authorize indemnification of, or advancement of such defense
          expenses to, its directors or other persons, in any such case to a
          greater extent than is permitted on such effective date, the
          references in this Article to "California law" shall to that extent be
          deemed to refer to California law as so amended.

                          BY-LAWS FOR THE REGULATION 

                                      OF 

                    MEN'S APPAREL GUILD IN CALIFORNIA, INC.

                                 SHAREHOLDERS
                                 ------------

     1.   Annual Meeting.  Unless the Board of Directors or the President of the
          --------------                                                        
corporation selects a different time or date, the annual meeting of shareholders
shall be held at 11:00 a.m. on the last Wednesday in February.  The annual
meeting shall be for the purpose of electing a Board of Directors and
transacting such other business as may properly be brought before the meeting.

     2.   Special Meeting. Special meetings of shareholders may be called at any
          ---------------
time by the Board of Directors, the Chairman of the Board, the President or the
holders of shares entitled to cast not less than one-tenth of the votes at the
meeting.

     3.   Place.  Meetings of shareholders shall be held at the principal
          -----                                                          
executive office of the corporation or at any other place, within or without
California, which is designated by the Board of Directors or the President.

     4.   Notice.
          ------ 

          (a) Annual and Special Meetings.  A written notice of each meeting of
              ---------------------------                                      
shareholders shall be given not more than 60 days and, except as provided below,
not less than 10 (or, if sent by third-class mail, 30) days before the meeting
to each shareholder entitled to vote at the meeting.  The notice shall state the
place, date and hour of the meeting and, if directors are to be elected at the
meeting, the names of the nominees intended to be presented by the Board of
Directors for election.  The notice shall also state (i) in the case of an
annual meeting, those matters which the Board of Directors intends to present
for action by the shareholders, and (ii) in the case of a special meeting, the
general nature of the business to be transacted and that no other business may
be transacted. Notice shall be delivered personally, by mail or other means
addressed to each such shareholder at the address of the shareholder appearing
on the books of the corporation, the address given by the shareholder to the
corporation for the purpose of notice or as otherwise provided by law.  Upon
written request to the Chairman of the Board, the President, the Secretary or
any Vice President of the corporation by any person (other than the Board of
Directors) entitled to call a special meeting of shareholders, the person
receiving such request shall cause notice to be given to the shareholders
entitled to vote that a meeting will be held at a time requested by the person
calling the meeting not less than 35 nor more than 60 days after receipt of the
request.

          (b) Adjourned Meetings.  Notice of an adjourned meeting need not be
              ------------------                                             
given if (i) the meeting is adjourned for 45 days or less, (ii) the time and
place of the adjourned meeting 
<PAGE>
 
are announced at the meting at which the adjournment is taken and (iii) no new
record date is fixed for the adjourned meeting. Otherwise, notice of the
adjourned meeting shall be given as in the case of an original meeting.

     5.   Record Date.  The Board of Directors may fix in advance a record date
          -----------                                                          
for the determination of the shareholders entitled to notice of any meeting, to
vote, to receive any dividend or other distribution or allotment of rights or to
exercise any rights. The record date shall be not more than 60 nor less than 10
days prior to the date of the meeting nor more than 60 days prior to such other
action. If no record date is fixed, the record date for determining shareholders
entitled to notice of or to vote at a meeting of shareholders shall be at the
close of business on the business day next preceding the day on which notice is
given or, if notice is waived, the close of business on the business day next
preceding the day on which the meeting is held. The record date for determining
shareholders entitled to give consent to corporate action in writing without a
meeting, when no prior action by the Board of Directors has been taken, shall be
the day on which the first written consent is given. The record date for
determining shareholders for any other purpose shall be at the close of business
on the day on which the Board of Directors adopts the resolution relating
thereto, or the 60th day prior to the date of such other action, whichever is
later. Except as otherwise provided by law, only shareholders at the close of
business on the record date are entitled to notice and to vote, to receive the
dividend, distribution or allotment of rights or to exercise rights, as the case
may be, notwithstanding any transfer of shares on the books of the corporation
occurring after the record date. Except as otherwise provided by law, the
corporation shall be entitled to treat the holder of record of any shares as the
holder in fact of such shares and shall not be bound to recognize any equitable
or other claim to or interest in such shares on the part of any other person,
whether or not the corporation shall have express or other notice of such claim
or interest. A determination of shareholders of record entitled to notice of or
to vote at a meeting of shareholders shall apply to any adjournment of the
meeting unless the Board of Directors fixes a new record date. The Board of
Directors shall fix a new record date if the adjourned meeting takes place more
than 45 days after the date set for the original meeting.

     6.   Meeting Without Regular Call and Notice.  The transactions of any
          ---------------------------------------                          
meeting of shareholders, however called and noticed and wherever held, are as
valid as though had at a meeting duly held after regular call and notice if a
quorum is present in person or by proxy and if, either before or after the
meeting, each of the persons entitled to vote who is not present at the meeting
in person or by proxy signs a written waiver of notice, a consent to the holding
of the meeting or an approval of the minutes of the meeting. Attendance of a
shareholder at a shareholders' meeting shall constitute a waiver of notice of
such meeting unless, at the beginning of the meeting, the shareholder objects to
the transaction of any business because the meeting was not properly called or
convened or, with respect to the consideration of a matter required to be
included in the notice for the meeting which was not so included, the
shareholder expressly objects to such consideration at the meeting.

     7.   Quorum and Required Vote.  A majority of the shares entitled to vote,
          ------------------------                                             
represented in person or by proxy, constitutes a quorum for the transaction of
business.  No business may be transacted at a meeting in the absence of a quorum
other than the adjournment of the meeting, 

                                      -2-
<PAGE>
 
except that if a quorum is present at the commencement of the meeting, business
may be transacted until the meeting is adjourned even though the withdrawal of
shareholders results in less than a quorum. If a quorum is present at a meeting,
the affirmative vote of the holders of shares having a majority of the voting
power of the shares represented and voting at the meeting on any matter shall be
the act of the shareholders unless the vote of a larger number or voting by
classes is required by law or the Articles of Incorporation. If a quorum is
present at the commencement of a meeting but the withdrawal of shareholders
results in less than a quorum, the affirmative vote of a majority of shares
required to constitute a quorum shall be the act of the shareholders unless the
vote of a larger number is required by law or the Articles of Incorporation. Any
meeting of shareholders, whether or not a quorum is present, may be adjourned by
the vote of a majority of the shares represented at the meeting.

     8.   Proxies.  A shareholder may be represented at any meeting of
          -------                                                     
shareholders by a written proxy signed by the person entitled to vote or by such
person's duly authorized attorney-in-fact.  A proxy must bear a date within 11
months prior to the meeting, unless the proxy specifies a different length of
time.  A revocable proxy is revoked by a writing delivered to the Secretary of
the corporation stating that the proxy is revoked or by a subsequent proxy
executed and delivered to the Secretary by, or by attendance at the meeting and
voting in person by, the person executing the proxy.

     9.   Voting.  Except as provided below or as otherwise provided by the
          ------                                                           
Articles of Incorporation or by law, a shareholder shall be entitled to one vote
for each share held of record on the record date fixed for the determination of
the shareholders entitled to vote or, if no such date is fixed, the date
determined in accordance with law.  Upon the demand of any shareholder made at a
meeting before the voting begins, the election of directors shall be by ballot.
At any election of directors, shareholders may cumulate votes and give one
candidate a number of votes equal to the number of directors to be elected
multiplied by the number of votes to which the shares are entitled or distribute
votes according to the same principle among as many candidates as desired.  No
shareholder shall be entitled to cumulate votes for any one or more candidates
unless such candidate or candidates' names have been placed in nomination prior
to the voting and at least one shareholder has given notice at the meeting prior
to the voting of such shareholder's intention to cumulate votes.

     10.  Election Inspectors.  One or three election inspectors may be
          -------------------                                          
appointed by the Board of Directors in advance of a meeting of shareholders or
at the meeting by the chairman of the meeting.  If not previously chosen, one or
three inspectors shall be appointed by the chairman of the meeting if a
shareholder or proxyholder so requests.  When inspectors are appointed at the
request of a shareholder or proxyholder, the majority of shares represented in
person or by proxy shall determine whether one or three inspectors shall be
chosen.  The election inspectors shall determine all questions concerning the
existence of a quorum and the right to vote, shall tabulate and determine the
results of voting and shall do all other acts necessary or helpful to the
expeditious and impartial conduct of the vote.  If there are three inspectors,
the decision, act or certificate of a majority of the inspectors is effective as
if made by all.

                                      -3-
<PAGE>
 
     11.  Action Without Meeting.  Except as provided below or by the Articles
          ----------------------                                              
of Incorporation, any action which may be taken at a meeting of shareholders may
be taken without a meeting and without prior notice if a consent in writing
setting forth the action so taken is signed by the holders of outstanding shares
having not less than the minimum number of votes which would be necessary to
authorize or take such action at a meeting at which all shares entitled to vote
on such action were present and voted.  Unless the consents of all shareholders
entitled to vote have been solicited in writing, the corporation shall give to
those shareholders entitled to vote who have not consented in writing (i) a
written notice at least 10 days before consummation of an action authorized by
shareholders without a meeting covered by the following Sections of the
California Corporations Code: 310 (certain transactions involving interested
directors), 317 (indemnification of corporate agents), 1201 (reorganizations)
and 2007 (certain distributions of assets) and (ii) a written notice promptly
after the taking of any other action approved by shareholders without a meeting.
Subject to Section 305(b) of the California Corporations Code, directors may not
be elected by written consent except by unanimous written consent of all shares
entitled to vote for the election of directors.

     12.  Reports.  The annual report to shareholders specified in Section 1501
          -------                                                              
of the California Corporations Code is dispensed with, except as the Board of
Directors may otherwise determine, as long as there are less than 100 holders of
record of the corporation's shares.  Any such annual report sent to shareholders
shall be sent at least 15 (or, if sent by third-class mail, 35) days prior to
the next annual meeting of shareholders and not later than 120 days after the
close of the fiscal year.

     13.  Lost Stock Certificates.  The corporation may cause a new stock
          -----------------------                                        
certificate to be issued in place of any certificate previously issued by the
corporation alleged to have been lost, stolen or destroyed.  The corporation
may, at its discretion and as a condition precedent to such issuance, require
the owner of such certificate to deliver an affidavit stating that such
certificate was lost, stolen or destroyed or to give the corporation a bond or
other security sufficient to indemnify it against any claim that may be made
against it, including any expense or liability, on account of the alleged loss,
theft or destruction or the issuance of a new certificate.

                               BOARD OF DIRECTORS
                               ------------------

     14.  Number.  The authorized number of directors of this corporation shall
          ------                                                               
be not less than three (3) nor more than five (5), provided, that (i) so long as
the Corporation has only one shareholder, the authorized number of directors
shall be no less than (1), and (ii) so long as the Corporation has only two
shareholders, the authorized number of directors shall be no less than two (2).
The exact number of directors shall be fixed by resolution of the Board of
Directors.  The indefinite number of directors may be changed or a definite
number fixed without provision for an indefinite number by an amendment to the
Articles of Incorporation or by amendment to these By-laws duly adopted by the
vote or written consent of holders of a majority of the outstanding shares
entitled to vote.  An amendment reducing the minimum number of directors to a
number less than five cannot be adopted if the votes cast against its adoption
at a meeting of the shareholders, or the shares not consenting in the case of
action by written consent, are equal to more than 16-2/3% of the outstanding
shares entitled to vote.  No amendment may change the 

                                      -4-
<PAGE>
 
maximum number of authorized directors to a number greater than two times the
minimum number of directors minus one.

     15.  Powers.  Subject to the limitations imposed by law or contained in the
          ------                                                                
Articles of Incorporation, the business and affairs of the corporation shall be
managed and all corporate powers shall be exercised by or under the ultimate
direction of the Board of Directors.

     16.  Election, Term of Office and Vacancies.  At each annual meeting of
          --------------------------------------                            
shareholders, directors shall be elected to hold office until the next annual
meeting.  Each director, including a director elected to fill a vacancy, shall
hold office until the expiration of the term for which the director was elected
and until a successor has been elected.  The Board of Directors may declare
vacant the office of any director who has been declared to be of unsound mind by
court order or convicted of a felony.  Vacancies on the Board of Directors not
caused by removal may be filled by a majority of the directors then in office,
regardless of whether they constitute a quorum, or by a sole remaining director.
The shareholders may elect a director at any time to fill any vacancy not
filled, or which cannot be filled, by the Board of Directors. No reduction in
the authorized number of directors shall have the effect of removing any
director prior to the expiration of his term of office.

     17.  Removal.  Except as provided below, any or all of the directors may be
          -------                                                               
removed without cause if such removal is approved by the affirmative vote or
written consent of a majority of the outstanding shares entitled to vote.
Unless the entire Board of Directors is so removed, no director may be removed
if (i) the votes cast against removal, or not consenting in writing to such
removal in the case of written consent, would be sufficient to elect such
director if voted cumulatively at an election at which the same total number of
votes was cast or, if such action is taken by written consent, all shares
entitled to vote were voted and (ii) the entire number of directors authorized
at the time of the director's most recent election were then being elected.

     18.  Resignation.  Any director may resign by giving notice to the Chairman
          -----------                                                           
of the Board, the President, the Secretary or the Board of Directors.  The
resignation of a director shall be effective when given unless the director
specifies a later time.  The resignation shall be effective regardless of
whether it is accepted by the corporation.

     19.  Compensation.  If the Board of Directors so resolves, the directors,
          ------------                                                        
including the Chairman of the Board, shall receive compensation and expenses of
attendance for meetings of the Board of Directors and of committees of the
Board.  Nothing herein shall preclude any director from serving the corporation
in another capacity and receiving compensation for such service.

     20.  Committees.  The Board of Directors may, by resolution adopted by a
          ----------                                                         
majority of the authorized number of directors, designate one or more
committees, each consisting of two or more directors, to serve at the pleasure
of the Board. The Board may designate one or more directors as alternate
members of a committee who may replace any absent member at any meeting of the
committee. To the extent permitted by the resolution of the Board of Directors,
a committee may exercise all of the authority of the Board except:

                                      -5-
<PAGE>
 
          (a) the approval of any action which, under the California
Corporations Code, must be approved by the outstanding shares or approved by the
shareholders;

          (b) the filling of vacancies on the Board or any committee;

          (c) the fixing of compensation of the directors for serving on the
Board or any committee;

          (d) the adoption, amendment or repeal of By-laws;

          (e) the amendment or repeal of any resolution of the Board which by
its express terms is not so amendable or repealable;

          (f) a distribution to the shareholders of the corporation, except at a
rate, in a periodic amount or within a price range determined by the Board; and

          (g) the appointment of any other committees of the Board or the
members of such committees.

     21.  Inspection of Records and Properties.  Each director may inspect all
          ------------------------------------                                
books, records, documents and physical properties of the corporation and its
subsidiaries at any reasonable time.  Inspections may be conducted either by the
director or the director's agent or attorney.  The right of inspection includes
the right to copy and make extracts.

     22.  Time and Place of Meetings and Telephone Meetings.  Unless the Board
          -------------------------------------------------                   
of Directors determines otherwise, the Board shall hold a regular meeting during
each quarter of the corporation's fiscal year.  One such meeting shall take
place immediately following the annual meeting of shareholders.  All meetings of
directors shall be held at the principal executive office of the corporation or
at such other place, within or without California, as shall be designated in the
notice of the meeting or in a resolution of the Board of Directors.  Directors
may participate in a meeting through use of conference telephone or similar
communications equipment, provided that all members so participating can hear
each other.

     23.  Call.  Meetings of the Board of Directors, whether regular or special,
          ----                                                                  
may be called by the Chairman of the Board, the President, the Secretary, any
Vice President or any two directors.

     24.  Notice.  Regular meetings of the Board of Directors may be held
          ------                                                         
without notice if the time of such meetings has been fixed by the Board.
Special meetings shall be held upon four days' notice by mail or 48 hours'
notice delivered personally or by telephone or telegraph, and regular meetings
shall be held upon similar notice if notice is required for such meetings.
Neither a notice nor a waiver of notice must specify the purpose of any regular
or special meeting.  Notice of the time and place of holding an adjourned
meeting need not be given to absent directors if the time and place of the
adjourned meeting is announced at the meeting at which the adjournment is taken,
but if a meeting is adjourned for more than 24 hours, notice of 

                                      -6-
<PAGE>
 
the adjourned meeting shall be given prior to the time of such meeting to the
directors who were not present at the time of the adjournment.

     25.  Meeting Without Regular Call and Notice.  The transactions of any
          ---------------------------------------                          
meeting of the Board of Directors, however called and noticed or wherever held,
are as valid as though had at a meting duly held after regular call and notice
if a quorum is present and if, either before or after the meeting, each of the
directors not present signs a written waiver of notice, a consent to the holding
of the meeting or an approval of the minutes of the meeting.  For such purposes,
a director shall not be considered present at a meeting if, although in
attendance at the meeting, the director protests the lack of notice prior to the
meeting or at its commencement.

     26.  Action Without Meeting.  Any action required or permitted to be taken
          ----------------------                                               
by the Board of Directors may be taken without a meeting, if all of the members
of the Board individually or collectively consent in writing to such action.

     27.  Quorum and Required Vote.  A majority of the authorized number of
          ------------------------                                         
directors then in office shall constitute a quorum for the transaction of
business, provided that, unless the authorized number of directors is one, the
number constituting a quorum shall not be less than the greater of one-third of
the authorized number of directors or two directors.  Subject to the provisions
of Section 310 (relating to certain transactions involving interested directors)
and Section 317(e) (relating to indemnification of corporate agents) of the
California Corporations Code, every act or decision done or made by a majority
of the directors present at a meeting duly held at which a quorum is present is
the act of the Board.  A meeting at which a quorum is initially present may
continue to transact business notwithstanding the withdrawal of directors, if
any action taken is approved by at least a majority of the required quorum for
such meeting.  A majority of the directors present at a meeting, whether or not
a quorum is present, may adjourn the meeting to another time and place.

     28.  Committee Meetings.  The principles set forth in Sections 22 through
          ------------------                                                  
27 of these By-laws shall apply to committees of the Board of Directors and to
actions taken by such committees.

     29.  Indemnification of Directors and Officers.
          ----------------------------------------- 

          (a) Indemnification. As authorized by the articles of incorporation,
              ---------------
to the fullest extent permissible under California law and in excess of that
which is expressly permitted by Section 317 of the California Corporations Code,
the corporation shall indemnify its directors and officers against all expenses,
judgments, fines, settlements and other amounts actually and reasonably incurred
by them in connection with any proceeding, including an action by or in the
right of the corporation, by reason of the fact that such person is or was a
director or officer of the corporation, or is or was serving at the request of
the corporation as a director, officer, trustee, employee or agent of another
corporation, or of a partnership, joint venture, trust or other enterprise
(including service with respect to employee benefit plans). To the fullest
extent permissible under California law, expenses incurred by a director or
officer seeking indemnification under this By-law in defending any proceeding
shall be advanced by the 

                                      -7-
<PAGE>
 
corporation as they are incurred upon receipt by the corporation of an
undertaking by or on behalf of the director or officer to repay such amount if
it shall ultimately be determined that the director or officer is not entitled
to be indemnified by the corporation for those expenses. If, after the effective
date of this By-law, California law is amended in a manner which permits the
corporation to authorize indemnification of or advancement of expenses to its
directors or officers, in any such case to a greater extent than is permitted on
such effective date, the references in this By-law to "California law" shall to
that extent be deemed to refer to California law as so amended. The rights
granted by this By-law are contractual in nature and, as such, may not be
altered with respect to any present or former director or officer without the
written consent of that person.

          (b) Procedure. Upon written request to the Board of Directors by a
              ---------
person seeking indemnification under this By-law, the Board shall promptly
determine in accordance with Section 317(e) of the California Corporations Code
whether the applicable standard of conduct has been met and, if so, the Board
shall authorize indemnification. If the Board cannot authorize indemnification
because the number of directors who are parties to the proceeding with respect
to which indemnification is sought prevents the formation of a quorum of
directors who are not parties to the proceeding, then, upon written request by
the person seeking indemnification, independent legal counsel (by means of a
written opinion obtained at the corporation's expense) or the corporation's
shareholders shall determine whether the applicable standard of conduct has been
met and, if so, shall authorize indemnification.

          (c) Definitions. The term "proceeding" means any threatened pending or
              -----------
completed action or proceeding, whether civil criminal, administrative or
investigative. The term "expenses" includes, without limitation, attorneys' fees
and any expenses of establishing a right to indemnification. 

                                   OFFICERS
                                   --------

include a Chairman of the Board or a President or both, a Secretary and a
Treasurer.  The Board of Directors may also choose one or more Vice Presidents,

and exercise their powers subject to the direction of the Board of Directors.

          (b) Execution of Corporate Instruments.  The Board of Directors may,
              ----------------------------------                              
in its discretion, determine the method and designate the signatory officer or
officers, or other person or persons, to execute any corporate instrument or
document, or to sign the corporate name without limitation, except where
otherwise provided by law, and such execution or signature shall be binding upon
the corporation.  Unless otherwise specifically determined by the Board of
Directors:

                                      -8-
<PAGE>
 
               (a) formal contracts of the corporation, promissory notes, deeds
          of trust, mortgages, and other evidences of indebtedness of the
          corporation, and other corporate instruments or documents requiring
          the corporate seal (except for share certificates issued by the
          corporation), and share certificates owned by the corporation, shall
          be executed, signed, or endorsed by the President, any Vice President,
          the Secretary or the Treasurer;

               (b) checks drawn on banks or other depositories on funds to the
          credit of the corporation, or in special accounts of the corporation,

          and by the President, any Vice President, the Secretary, or the
          Treasurer;

               (c) dividend warrants, drafts, insurance policies, and all other
          instruments and documents requiring the corporate signature, but not
          requiring the corporate seal, shall be executed or signed by the
          President, any Vice President, the Secretary, or the Treasurer;

               (d) share certificates issued by the corporation shall be signed
          (which may be a facsimile signature) jointly by (i) the President or a
          Vice President and (ii) the secretary or an Assistant Secretary.

          (c)  Ratification by Shareholders.  The Board of Directors may, in its
               ----------------------------                                     
discretion, submit any contract or act for approval or ratification by the
shareholders at any annual meeting of shareholders or at any special meeting of
shareholders called for that purpose.  Any contract or act which shall be
approved or ratified by the holders of a majority of the voting power of the
corporation represented at such meeting shall be as valid and binding upon the
Corporation as though approved or ratified by each and every shareholder of the
Corporation, unless a greater vote is required by law for such purpose.

          (d)  Voting of Shares Owned by the Corporation.  All shares of other
               -----------------------------------------                      
corporations owned or held by the corporation for itself or for other parties in
any capacity shall be voted, and all proxies with respect thereto shall be
executed, by the person authorized to do so by resolution of the Board or, in
the absence of such authorization, by the President, any of the Vice Presidents,
the Secretary or any Assistant Secretary.

     31.  Election, Term of Office and Vacancies.  At its regular meeting after
          --------------------------------------                               
each annual meeting of shareholders, the Board of Directors shall choose the
officers of the corporation.  The Board may choose additional officers or fill
vacant offices at any other time.  No officer must be a member of the Board of
Directors except the Chairman of the Board.  The officers shall hold office
until their successors are chosen, except that the Board of Directors may remove
any officer at any time.

     32.  Resignation.  Any officer may resign at any time upon notice to the
          -----------                                                        
corporation without prejudice to the rights, if any, of the corporation under
any contract to which the officer is a party.  The resignation of an officer
shall be effective when given unless the officer specifies 

                                      -9-
<PAGE>
 
a later time. The resignation shall be effective regardless of whether it is
accepted by the corporation.

     33.  Chairman of the Board; President.  If the Board of Directors elects a

Chairman of the Board, such officer shall preside over all meetings of the Board
of Directors and of shareholders.  If there be no Chairman of the Board, the
President shall perform such duties.  The Board of Directors shall designate

and may prescribe the duties and powers of the chief executive officer.  If
there be no Chairman of the Board, the President shall be the chief executive
officer.

     34.  Secretary.  Unless otherwise determined by the Board of Directors or
          ---------

a majority of the outstanding shares entitled to vote or by the Board of

Incorporation, as the same may be amended or restated from time to time, to the
extent that the California Corporations Code permits such provision, if set
forth in the Articles of Incorporation, to supervene, to modify or to constitute
an exception or supplement to any provision of these By-laws.

                                   ARTICLE I

                                    OFFICES


     Section 1.  PRINCIPAL OFFICES. The Board of Directors shall fix the 
location of the principal executive office of the corporation at any place 
within or outside the State of California. If the principal executive office is 
located outside this state, and the corporation has one or more business offices
in this state, the Board of Directors shall likewise fix and designate a 
principal business office in the State of California.

     Section 2.  OTHER OFFICES. The Board of Directors may at any time establish
branch or subordinate offices at any place or places where the corporation is 
qualified to do business.


                                  ARTICLE II

                           MEETINGS OF SHAREHOLDERS

     Section 1.  PLACE OF MEETINGS. Meetings of shareholders shall be held at
any place within or outside the State of California designated by the Board of
Directors. In the absence of any such designation, shareholders' meetings shall
be held at the principal executive office of the corporation.

     Section 2.  ANNUAL MEETINGS OF SHAREHOLDERS. The annual meeting of 
shareholders shall be held each year on a date and at a time designated by the 
Board of Directors. At each annual meeting directors shall be elected and any 
other proper business may be transacted.

     Section 3.  SPECIAL MEETINGS. A special meeting of the shareholders may be 
called at any time by the Board of Directors, or by the Chairman of the Board, 
or by the President, or by one or more shareholders holding shares in the 
aggregate entitled to cast not less than 10% of the votes at any such meeting.

     If a special meeting is called by any person or persons other than the 
Board of Directors, the request shall be in writing, specifying the time of such
meeting and the general nature of the business proposed to be transacted, and 
shall be delivered personally or sent by registered mail or by telegraphic or 
other facsimile transmission to the Chairman of the Board, the President, any 
Vice President or the Secretary of the corporation. The officer receiving such 
request forthwith shall cause notice to be given to the shareholders entitled to
vote, in accordance with the provisions of Sections 4 and 5 of


<PAGE>
 
this Article II, that a meeting will be held at the time requested by the person
or persons calling the meeting, not less than thirty-five (35) or more than 
sixty (60) days after the receipt of the request. If the notice is not given 
within twenty (20) days after receipt of the request, the person or persons 
requesting the meeting may give the notice. Nothing contained in this paragraph 
of this Section 3 shall be construed as limiting, fixing or affecting the time 
when a meeting of shareholders called by action of the Board of Directors may be
held.

     Section 4.  NOTICE OF SHAREHOLDERS' MEETINGS. All notices or meetings of 
shareholders shall be sent or otherwise given in accordance with Section 5 of 
this Article II not less than ten (10) nor more than sixty (60) days before the
date of the meeting being noticed. The notice shall specify the place, date and
hour of the meeting and (i) in the case of a special meeting, the general nature
of the business to be transacted, or (ii) in the case of the annual meeting
those matters which the Board of Directors, at the time of giving the notice,
intends to present for action by the shareholders. The notice of any meeting at
which directors are to be elected shall include the name of any nominee or
nominees which, at the time of the notice, management intends to present for
election.

     If action is proposed to be taken at any meeting for approval of (i) a 
contract or transaction in which a director has a direct or indirect financial
interest, pursuant to Section 310 of the Corporations Code of California, (ii)
an amendment of the articles of incorporation, pursuant to Section 902 of such
Code, (iii) a reorganization of the corporation, pursuant to Section 1201 of
such Code, (iv) a voluntary dissolution of the corporation, pursuant to Section
1900 of such Code, or (v) a distribution in dissolution other than in accordance
with the rights of outstanding preferred shares pursuant to Section 2007 of such
Code, the notice shall also state the general nature of such proposal.

     Section 5.  MANNER OF GIVING NOTICE: AFFIDAVIT OF NOTICE. Notice of any 
meeting of shareholders shall be given either personally or by first-class mail 
or telegraphic or other written communication, charges prepaid, addressed to the
shareholder at the address of such shareholder appearing on the books of the 
corporation or given by the shareholder to the corporation for the purpose of 
notice. If no such address appears on the corporation's books or has been so 
given, notice shall be deemed to have been given if sent by first-class mail or 
telegraphic or other written communication to the corporation's principal 
executive office, or if published at least once in a newspaper of general 
circulation in the county where such office is located. Notice shall be deemed 
to have been given at the time when delivery personally or deposited in the mail
or sent by telegram or other means of written communication.

     If any notice addressed to a shareholder at the address of such shareholder
appearing on the books of the corporation is returned to the corporation by the
United States Postal Service marked to indicate that the United States Postal
Service is unable to deliver the notice to the shareholder at such address, all
future notices or reports shall be deemed to have been duly given without
further mailing if the same shall be available to

<PAGE>
 
the shareholder upon written demand of the shareholder at the principal 
executive office of the corporation for a period of one year from the date of 
the giving of such notice.

     An affidavit of the mailing or other means of giving any notice of any 
shareholders' meeting shall be executed by the Secretary, Assistant Secretary or
any transfer agent of the corporation giving such notice, and shall be filed and
maintained in the minute book of the corporation.

     Section 6.  QUORUM. The presence in person or by proxy of the holders of a 
majority of the shares entitled to vote at any meeting of shareholders shall 
constitute a quorum for the transaction of business. The shareholders present at
a duly called or held meeting at which a quorum is present may continue to do 
business until adjournment, notwithstanding the withdrawal of enough 
shareholders to leave less than a quorum, if any action taken (other than 
adjournment) is approved by at least a majority of the shares required to 
constitute a quorum.

     Section 7.  ADJOURNED MEETING AND NOTICE THEREOF. Any shareholders' 
meeting, annual or special, whether or not a quorum is present, may be adjourned
from time to time by the vote of the majority of the shares represented at such 
meeting, either in person or by proxy, but in the absence of a quorum, no other 
business may be transacted at such meeting, except as provided in Section 6 of 
this Article II.

     When any meeting of shareholders, either annual or special, is adjourned to
another time or place, notice need not be given of the adjourned meeting if the 
time and place thereof are announced at the meeting at which the adjournment is 
taken, unless a new record date for the adjourned meeting is fixed, or unless 
the adjournment is for more than forty-five (45) days from the date set for the 
original meeting, in which case the Board of Directors shall set a new record 
date. Notice of any such adjourned meeting, if required, shall be given to each 
shareholder of record entitled to vote at the adjourned meeting in accordance 
with the provisions of Sections 4 and 5 of this Article II. At any adjourned 
meeting the corporation may transact any business which might have been 
transacted at the original meeting.

     Section 8.  VOTING. The shareholders entitled to vote at any meeting of 
shareholders shall be determined in accordance with the provisions of Section 11
of this Article II, subject to the provisions of Section 702 to 704, inclusive, 
of the Corporations Code of California (relating to voting shares held by a 
fiduciary, in the name of a corporation or in joint ownership). Such vote may be
by voice vote or by ballot; provided, however, that all elections for directors 
must be by ballot upon demand by a shareholder at any election and before the 
voting begins. Any shareholder entitled to vote on any matter (other than the 
election of directors) may vote part of the shares in favor of the proposal and 
refrain from voting the remaining shares or vote them against the proposal, but,
if the shareholder fails to specify the number of shares such shareholder is 
voting affirmatively, it will be conclusively presumed that the shareholder's 
approving vote is with respect to all shares such shareholder is entitled to 
vote. If a quorum is

<PAGE>
 
present, the affirmative vote of the majority of the shares represented at the 
meeting and voting on any matter (other than the election of directors), 
provided that the shares voting affirmatively must also constitute at least a 
majority of the required quorum, shall be the act of the shareholders, unless 
the vote of a greater number or voting by classes is required by the California 
General Corporation Law or the articles of incorporation.

     At a shareholders' meeting involving the election of directors, no 
shareholder shall be entitled to cumulate votes (i.e., cast for any candidate a 
number of votes greater than the number of the shareholder's shares) unless such
candidate or candidates' names have been placed in nomination prior to 
commencement of the voting and a shareholder has given notice prior to 
commencement of the voting of the shareholders' intention to cumulate votes. If 
any shareholder has given such notice, then every shareholder entitled to vote
may cumulate such shareholder's votes for candidates in nomination and give one
candidate a number of votes equal to the number of directors to be elected
multiplied by the number of votes to which such shareholder's shares are
entitled, or distribute the shareholder's votes on the same principle among any
or all of the candidates, as the shareholder thinks fit. The candidates
receiving the highest number of votes, up to the number of directors to be
elected, shall be elected.

     Section 9.  WAIVER OF NOTICE OR CONSENT BY ABSENT SHAREHOLDERS. The 
transactions of any meeting of shareholders, either annual or special, however 
called and noticed, and wherever held, shall be as valid as though had at a 
meeting duly held after regular call and notice, if a quorum be present either 
in person or by proxy, and if, either before or after the meeting, each person 
entitled to vote, not present in person or by proxy, signs a written waiver of 
notice or a consent to the holding of the meeting, or an approval of the minutes
thereof. The waiver of notice or consent need not specify either the business to
be transacted or the purpose of any annual or special meeting of shareholders, 
except that if action is taken or proposed to be taken for approval of any of 
those matters specified in the second paragraph of Section 4 of this Article II,
the waiver of notice or consent shall state the general nature of such proposal.
All such waivers, consents or approvals shall be filed with the corporate 
records or made a part of the minutes of the meeting.

     Attendance of a person at a meeting shall also constitute a waiver of
notice of such meeting, except when the person objects, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened, and except that attendance at a meeting is not a waiver of
any right to object to the consideration of matters not included in the notice
of the meeting if such objection is expressly made at the meeting.

     Section 10. SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING. Any 
action which may be taken at any annual or special meeting of shareholders may 
be taken without a meeting and without prior notice, if a consent in writing, 
setting forth the action so taken, is signed by the holders of outstanding 
shares having not less than the minimum number of votes that would be necessary 
to authorize

<PAGE>
 
or take such action at a meeting at which all shares entitled to vote thereon 
were present and voted. In the case of election of directors, such consent shall
be effective only if signed by the holders of all outstanding shares entitled to
vote for the election of directors; provided, however, that a director may be 
elected at any time to fill a vacancy not created by removal and not filled by 
the directors by the written consent of the holders of a majority of the 
outstanding shares entitled to vote for the election of directors. All such 
consents shall be filed with the Secretary of the corporation and shall be 
maintained in the corporate records. Any shareholder giving a written consent, 
or the shareholder's proxy holders, or a transferee of the shares or a personal 
representative of the shareholder or their respective proxy holder, may revoke 
the consent by a writing received by the Secretary of the corporation prior to 
the time that written consents of the number of shares required to authorize the
proposed action have been filed with the Secretary.

     Unless the consents of all shareholders entitled to vote have been 
solicited in writing, the Secretary shall give prompt notice of any corporate 
action approved by the shareholders without a meeting by less than unanimous 
consent, to those shareholders entitled to vote who have not consented in 
writing. Such notice shall be given in the manner specified in Section 5 of this
Article II. In the case of approval of (i) contracts or transactions in which a 
director has a direct or indirect financial interest, pursuant to Section 310 of
the Corporations Code of California, (ii) indemnification of agents of the
corporation, pursuant to Section 317 of such Code, (iii) a reorganization of the
corporation, pursuant to Section 1201 of such Code, or (iv) a distribution in
dissolution other than in accordance with the rights of outstanding preferred
shares pursuant to Section 2007 of such Code, such notice shall be given at
least ten (10) days before the consummation of any such action authorized by any
such approval.
 
     Section 11. RECORD DATE FOR SHAREHOLDER NOTICE, VOTING, AND GIVING 
CONSENTS. For purposes of determining the shareholders entitled to notice of any
meeting to vote or entitled to give consent to corporate action without a 
meeting, the Board of Directors may fix, in advance, a record date, which shall 
not be more than sixty (60) days nor less than ten (10) days prior to the date 
of any such meeting nor more than sixty (60) days prior to such action without a
meeting, and in such case only shareholders of record at the close of business 
on the date so fixed are entitled to notice and to vote or to give consents, as 
the case may be, notwithstanding any transfer of any shares on the books of the 
corporation after the record date fixed as aforesaid, except as otherwise 
provided in the California General Corporation Law.

     If the Board of Directors does not so fix a record date:

          (a)  The record date for determining shareholders entitled to notice
     of or to vote at a meeting of shareholders shall be at the close of
     business on the business day next preceding the day on which notice if
     given or, if notice is waived, at the close of business on the business day
     next preceding the day on which the meeting is held.

<PAGE>
 
          (b)  The record date for determining shareholders entitled to give
     consent to corporate action in writing without a meeting, (i) when no prior
     action by the Board has been taken, shall be the day on which the first
     written consent is given, or (ii) when prior action of the Board has been
     taken, shall be at the close of business on the day on which the Board
     adopts the resolution relating thereto, or the sixtieth (60th) day prior to
     the date of such other action, whichever is later.

     Section 12. PROXIES. Every person entitled to vote for directors or on any 
other matter shall have the right to do so either in person or by one or more 
agents authorized by a written proxy signed by the person and filed with the 
Secretary of the corporation. A proxy shall be deemed signed if the 
shareholder's name is placed on the proxy (whether by manual signature, 
typewriting, telegraphic transmission or otherwise) by the shareholder or the 
shareholder's attorney in fact. A validly executed proxy which does not state 
that it is irrevocable shall continue in full force and effect unless (i) 
revoked by the person executing it, prior to the vote pursuant thereto, by a 
writing delivered to the corporation stating that the proxy is revoked or by a 
subsequent proxy presented to the meeting and executed by, or attendance at the 
meeting and voting in person by, the person executing the proxy; or (ii) written
notice of the death or incapacity of the maker of such proxy is received by the 
corporation before the vote pursuant thereto is counted; provided, however, that
no such proxy, unless otherwise provided in the proxy. The revocability of a 
proxy that states on its face that it is irrevocable shall be governed by the 
provisions of Section 705(e) and (f) of the Corporations Code of California.

     Section 13. INSPECTORS OF ELECTION. Before any meeting of shareholders, the
Board of Directors may appoint any persons other than nominees for office to act
as inspectors of election at the meeting or its adjournment. If not inspectors 
of election are so appointed, the chairman of the meeting may, and on the 
request of any shareholder or a shareholder's proxy shall, appoint inspectors of
election at the meeting. The number of inspectors shall be either one (1) or 
three (3). If inspectors are appointed at a meeting on the request of one or 
more shareholders or proxies, the holders of a majority of shares or their 
proxies present at the meeting shall determine whether one (1) or three (3) 
inspectors are to be appointed. If any person appointed as inspector fails to 
appear or fails or refuses to act, the chairman of the meeting may, and upon the
request of any shareholder or a shareholder's proxy shall, appoint a person to 
fill such vacancy.

     The duties of these inspectors shall be as follows:

          (a)  Determine the number of shares outstanding and the voting power
     of each, the shares represented at the meeting, the existence of a quorum,
     and the authenticity, validity and effect of proxies;

          (b)  Receive votes, ballots or consents;

<PAGE>
 
          (c)  Hear and determine all challenges and questions in any way 
     arising in connection with the right to vote;

          (d)  Count and tabulate all votes or consents;

          (e)  Determine when the polls shall close;

          (f)  Determine the result; and

          (g)  Do any other acts that may be proper to conduct the election or 
     vote with fairness to all the shareholders.

                                  ARTICLE III

                                   DIRECTORS

     Section 1.  POWERS. Subject to the provisions of the California General 
Corporation Law and any limitations in the articles of incorporation and these 
bylaws relating to action required to be approved by the shareholders or by the 
outstanding shares, the business and affairs of the corporation shall be managed
and all corporate powers shall be exercised by or under the direction of the 
Board of Directors.

     Without prejudice to such general powers, but subject to the same 
limitations, it is hereby expressly declared that the directors shall have the 
power and authority to:

          (a)  Select and remove all officers, agents, and employees of the
     corporation, prescribe such powers and duties for them as may not be
     inconsistent with law, the articles of incorporation or these bylaws, fix
     their compensation, and require from them security for faithful service.

          (b)  Change the principal executive office or the principal business
     office in the State of California from one location to another; cause the
     corporation to be qualified to do business in any other state, territory,
     dependency, or foreign country and conduct business within or outside the
     State of California; designate any place within or without the State for
     the holding of any shareholders' meeting or meetings, including annual
     meetings; adopt, make and use a corporate seal, and prescribe the forms of
     certificates of stock, and alter the form of such seal and of such
     certificates from time to time as in their judgment they may deem best,
     provided that such forms shall at all times comply with the provisions of
     law.

          (c)  Authorize the issuance of shares of stock of the corporation from
     time to time, upon such terms as may be lawful, in consideration of money
     paid, labor done or services actually rendered, debts or securities
     cancelled or tangible or intangible property actually received.

<PAGE>
 
          (d)  Borrow money and incur indebtedness for the purposes of the
     corporation, and cause to be executed and delivered therefor, in the
     corporate name, promissory notes, bonds, debentures, deeds of trust,
     mortgages, pledges, hypothecations or other evidences of debt and
     securities therefor.

     Section 2.  NUMBER AND QUALIFICATION OF DIRECTORS. The authorized number of
directors shall be two (2) until changed by an amendment to this bylaw adopted 
by the vote or written consent of holders of a majority of the outstanding 
shares entitled to vote; provided, however, that an amendment reducing the 
number of directors to a number less than five (5) cannot be adopted if the 
votes cast against its adoption at a meeting, or the shares not consenting in 
the case of action by written consent, are equal to more than 16-2/3% of the 
outstanding shares entitled to vote.

     Section 3.  ELECTION AND TERM OF OFFICE OF DIRECTORS. Director shall be 
elected at each annual meeting of the shareholders to hold office until the next
annual meeting. Each director, including a director elected to fill a vacancy, 
shall hold office until the expiration of the term for which elected and until a
successor has been elected and qualified.

     Section 4.  VACANCIES. Vacancies in the Board of Directors may be filled by
a majority of the remaining directors, though less than a quorum, or by a sole 
remaining director, except that a vacancy created by the removal of a director 
by the vote or written consent of the shareholders or by court order may be 
filled only by the vote of a majority of the shares represented and voting at a 
duly held meeting at which a quorum is present, or by the written consent of 
holders of all outstanding shares entitled to vote. Each director so elected 
shall hold office until the next annual meeting of the shareholders and until a 
successor has been elected and qualified.

     A vacancy or vacancies in the Board of Directors shall be deemed to exist 
in the case of death, resignation or removal of any director, or if the Board of
Directors by resolution declares vacant the office of a director who has been 
declared of unsound mind by an order of court or convicted of a felony, or if 
the authorized number of directors by increased, or if the shareholders fail, at
any meeting of shareholders at which any director or directors are elected, to 
elect the full authorized number of directors to be voted for at that meeting.

     The shareholders may elect a director or directors at any time to fill any 
vacancy or vacancies not filled by the directors, but any such election by 
written consent, other than to fill a vacancy created by removal, shall require 
the consent of a majority of the outstanding share entitled to vote.

     Any director may resign upon giving written notice to the Chairman of the 
Board, the President, the Secretary or the Board of Directors. A resignation 
shall be effective upon the giving of the notice, unless the notice specifies a 
later time for its effectiveness.
     
<PAGE>
 
If the resignation of a director is effective at a future time, the Board of 
Directors may elect a successor to take office when the resignation becomes 
effective.

     No reduction of the authorized number of directors shall have the effect of
removing any director prior to the expiration of his term of office.
     
     Section 5.  PLACE OF MEETINGS AND TELEPHONIC MEETINGS. Regular meetings of 
the Board of Directors may be held at any place within or without the State that
has been designated from time to time by resolution of the board. In the absence
of such designation, regular meetings shall be held at the principal executive
office of the corporation. Special meetings of the board shall be held at any
place within or without the State that has been designated in the notice of the
meeting or, if not stated in the notice or there is no notice, at the principal
executive office of the corporation. Any meeting, regular or special, may be
held by conference telephone or similar communication equipment, so long as all
directors participating in such meeting can hear one another, and all such
directors shall be deemed to be present in person at such meeting.

     Section 6.  ANNUAL MEETING. Immediately following each annual meeting of 
shareholders, the Board of Directors shall hold a regular meeting for the 
purpose of organization, any desired election of officers and the transaction of
other business. Notice of this meeting shall not be required.

     Section 7.  OTHER REGULAR MEETINGS. Other regular meetings of the Board of 
Directors shall be held without call at such time as shall from time to time be 
fixed by the Board of Directors. Such regular meeting may be held without 
notice.

     Section 8.  SPECIAL MEETINGS. Special meetings of the Board of Directors 
for any purpose or purposes may be called at any time by the Chairman of the 
Board or the President or any Vice President or the Secretary or any two 
directors.

     Notice of the time and place of special meetings shall be delivered 
personally or by telephone to each director or sent by first-class mail or 
telegram, charges prepaid, addressed to each director at his or her address as 
it is shown upon the records of the corporation. In case such notice is mailed, 
it shall be deposited in the United States mail at least four (4) days prior to 
the time of the holding of the meeting. In case such notice is delivered 
personally, or by telephone or telegram, it shall be delivered personally or by 
telephone or to the telegraph company at least forty-eight (48) hours prior to 
the time of the holding of the meeting. Any oral notice given personally or by 
telephone may be communicated to either the director or to a person at the 
office of the director who the person giving the notice has reason to believe 
will promptly communicate it to the director. The notice need not specify the 
purpose of the meeting nor the place if the meeting is to be held at the 
principal executive office of the corporation.

<PAGE>
 
     Section 9.  DISPENSING WITH NOTICE. The transactions of any meeting of the 
Board of Directors, however called and noticed or wherever held, shall be as 
valid as though had at a meeting duly held after regular call and notice if a 
quorum be present and if, either before or after the meeting, each of the 
directors not present signs a written waiver of notice, a consent to holding the
meeting or an approval of the minutes thereof. The waiver of notice or consent 
need not specify the purpose of the meeting. All such waivers, consents and 
approvals shall be filed with the corporate records or made a part of the 
minutes of the meeting. Notice of a meeting need not be given to any director 
who attends the meeting without protesting, prior thereto or at its 
commencement, the lack of notice to such director.

     Section 10. QUORUM. A majority of the authorized number of directors shall 
constitute a quorum for the transaction of business, except to adjourn as 
hereinafter provided. Every act or decision done or made by a majority of the 
directors present at a meeting duly held at which a quorum is present shall be 
regarded as the act of the Board of Directors, subject to the provisions of 
Section 310 of the Corporations Code of California (approval of contracts or 
transactions in which a director has a direct or indirect material financial 
interest), Section 311 (appointment of committees), and Section 317(e) 
(indemnification of directors). A meeting at which a quorum is initially present
may continue to transact business notwithstanding the withdrawal of directors, 
if any action taken is approved by at least a majority of the required quorum 
for such meeting.

     Section 11. ADJOURNMENT. A majority of the directors present, whether or 
not constituting a quorum, may adjourn any meeting to another time and place.

an adjourned meeting need not be given, unless the meeting is adjourned for more
than twenty-four (24) hours, in which case notice of such time and place shall 
be given prior to the time of the adjourned meeting, in the manner specified in 
Section 8 of this Article III, to the directors who were not present at the time
of the adjournment.

     Section 13. ACTION WITHOUT MEETING. Any action required or permitted to be 
taken by the Board of Directors may be taken without a meeting, if all members 
of the board shall individually or collectively consent in writing to such 
action. Such action by written consent shall have the same force and effect as a
unanimous vote of the Board of Directors. Such written consent or consents shall
be filed with the minutes of the proceedings of the board.

     Section 14. FEES AND COMPENSATION OF DIRECTORS. Directors and member of 
committees may receive such compensation, if any, for their services, and such 
reimbursement of expenses, as may be fixed or determined by resolution of the 
Board of Directors. Nothing herein contained shall be construed to preclude any 
director from serving the corporation in any other capacity as an officer, 
agent, employee, or otherwise, and receiving compensation for such services.

                                  ARTICLE VI

               INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES

                               AND OTHER AGENTS

     The corporation shall, to the maximum extent permitted by the General 
Corporation Law of California, indemnify each of its directors and officers

reasonably incurred in connection with any proceeding arising by reason of the

such proceeding to the maximum extent permitted by such law.  For purposes of

serving at the request of the corporation as a director or officer of another
corporation, or other enterprise, or was a director or officer of a corporation

<PAGE>
 
corporation. The Board of Directors may in its discretion provide by resolution

corporation, and likewise may refuse to provide for such indemnification or 
advance of expenses except to the extent such indemnification is mandatory under
the California General Corporate Law.

                                  ARTICLE VII

shall keep at its principal executive office, or at the office of its transfer 
agent or registrar, if either be appointed and as determined by resolution of 
the Board of Directors, a record of its shareholders, giving the names and 
addresses of all shareholders and the number and class of shares held by each 
shareholder.

     A shareholder or shareholders of the corporation holding at least five
percent (5%) in the aggregate of the outstanding voting shares of the
corporation may (i) inspect and copy the records of shareholders' names and
addresses and shareholders during usual business hours upon five (5) business
days prior written demand upon the corporation, and/or (ii) obtain from the
transfer agent of the corporation, upon written demand and upon the tender of
such transfer agent's usual charges for such list, a list of the shareholders'
names and addresses, who are entitled to vote for the election of directors, and
their shareholdings, as of the most recent record date for which such list has
been compiled or as of a date specified by the shareholder subsequent to the
date of demand. Such list shall be made available to such shareholder or
shareholders by the transfer agent on or before the later of five (5) business
days after the demand is received or the date specified therein as the date as
of which the list is to be compiled. The record of shareholders shall also be
open to inspection upon the written demand of any shareholder or holder of a
voting trust certificate, at any time during usual business hours, for a purpose
reasonably related to such holder's interests as a shareholder or as the holder
of a voting trust certificate. Any inspection and copying under this Section 1
may be made in person or by an agent or attorney of the shareholder or holder of
a voting trust certificate making such demand.

     Section 2. MAINTENANCE AND INSPECTION OF BYLAWS. The corporation shall keep
at its principal executive office, or if its principal executive office is not
in the State of California at its principal business office in the state, the
original or a copy of the bylaws as amended to date, which shall be open to
inspection by the shareholders at all reasonable times during office hours. If
the principal executive office of the corporation is outside this state and the
corporation has no principal business office in this state, the Secretary
shall, upon written request of any shareholder, furnish to such shareholder a
copy of the bylaws as amended to date.



<PAGE>
 
     Section 3.  MAINTENANCE AND INSPECTION OF OTHER CORPORATE RECORDS.  The 
accounting books and records and minutes of proceedings of the shareholders and 
the Board of Directors and any committee or committees of the Board of Directors
shall be kept as such place or places designated by the Board of Directors, or, 
in the absence of such designation, at the principal executive office of the 
corporation.  The minutes shall be kept in written form and the accounting books
and records shall be kept either in written form or in any other form capable of
being converted into written form.  Such minutes and accounting books and 
records shall be open to inspection upon the written demand of any shareholder 
or holder of a voting trust certificate, at any reasonable time during usual 
business hours, for a purpose reasonably related to such holder's interests as a
shareholder or as the holder of a voting trust certificate.  Such inspection may
be made in person or by an agent or attorney, and shall include the right to 
copy and make extracts.  The foregoing rights of inspection shall extend to the 
records of each subsidiary corporation of the corporation.

     Section 4.  INSPECTION BY DIRECTORS. Every director shall have the absolute
right at any reasonable time to inspect all books, records and documents of
every kind and the physical properties of the corporation and each of its
subsidiary corporations. Such inspection by a director may be made in person or
by agent or attorney and the right of inspection includes the right to copy and
make extracts.

     Section 5.  ANNUAL REPORT TO SHAREHOLDERS.  The annual report to 
shareholders referred to in Section 1501 of the General Corporation Law is 
expressly dispensed with, but nothing herein shall be interpreted as prohibiting
the Board of Directors from issuing annual or other periodic reports to the 
shareholders of the corporations as they deem appropriate.

     Section 6.  FINANCIAL STATEMENTS.  A copy of annual financial statement and
any income statement of the corporation for each quarterly period of each fiscal
year, and any accompanying balance sheet of the corporation as of the end of 
each such period, that has been prepared by the corporation shall be kept on 
file in the principal executive office of the corporation for twelve (12) months
and each such statement shall be exhibited at all reasonable times to any 
shareholder demanding an examination of any such statement or a copy shall be 
mailed to any such shareholder.

     If the Corporation has not sent to the shareholders an annual report for 
the last fiscal year, a balance sheet as of the end of such fiscal year and an 
income statement and statement of changes in financial position for such fiscal 
year shall, upon the written request of any shareholder made more than one 
hundred twenty (120) days after the close of such fiscal year, be delivered or 
mailed to such shareholder within thirty (30) days after such request.

     If a shareholder or shareholders holding at least five percent (5%) of the 
outstanding shares of any class of stock of the corporation make a written 
request to the corporation for an income statement of the corporation for the 
three-month, six-month or
<PAGE>
 
nine-month period of the current fiscal year ended more than thirty (30) days
prior to the date of the request, and a balance sheet of the corporation as of
the end of such period, the Chief Financial Officer shall cause such statement
to be prepared, if not already prepared, and shall deliver personally or mail
such statement or statements to the person making the request within thirty (30)
days after the receipt of such request.

     The corporation also shall, upon the written request of any shareholder, 
mail to the shareholder a copy of the last annual, semi-annual or quarterly 
income statement which it has prepared and a balance sheet as of the end of such
period.

     The quarterly income statements and balance sheets referred to in this 
section shall be accompanied by the report thereon, if any, of any independent 
accountants engaged by the corporation or the certificate of an authorized 
officer of the corporation that such financial statements were prepared without 
audit from the books and records of the corporation.

     Section 7.  ANNUAL STATEMENT OF GENERAL INFORMATION. The corporation shall
each year during the calender month in which its articles of incorporation were
originally filed with the California Secretary of State, or at any time during
the immediately preceding five (5) calender months, file with the Secretary of
State of the State of California, on the prescribed form, a statement setting
forth the names and complete business or residence addresses of all incumbent
directors, the number of vacancies on the Board of Directors, if any, the names
and complete business or residence addresses of the Chief Executive Officer,
Secretary and Chief Financial Officer, the street address of its principal
executive office or principal business office in this state and the general type
of business constituting the principal business activity of the corporation,
together with a designation of the agent of the corporation for the purpose of
service of process, all in compliance with Section 1502 of the Corporations Code
of California.

                                 ARTICLE VIII

                           GENERAL CORPORATE MATTERS

     Section 1.  RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING. For
purposes of determining the shareholders entitled to receive payment of any
dividend or other distribution or allotment of any rights or entitled to
exercise any rights in respect of any other lawful action, (other than action by
shareholders by written consent without a meeting) the Board of Directors may
fix, in advance, a record date, which shall not be more than sixty (60) days
prior to any such action, and in such case only shareholders of record on the
date so fixed are entitled to receive the dividend, distribution or allotment of
rights or to exercise the rights, as the case may be, notwithstanding any
transfer of any shares on the books of the corporation after the record date
fixed as aforesaid, except as otherwise provided in the California General
Corporation Law.

<PAGE>
 
     If the Board of Directors does not so fix a record date, the record date
for determining shareholders for any such purpose shall be at the close of
business on the day on which the board adopts the resolution relating thereto,
or the sixtieth (60th) day prior to the date of such action, whichever is later.

     Section 2. CHECKS, DRAFTS, EVIDENCES OF INDEBTEDNESS. All checks, drafts or
other orders for payment of money, notes or other evidences of indebtedness, 
issued in the name of or payable to the corporation, shall be signed or endorsed
by such person or persons and in such manner as, from time to time, shall be 
determined by resolution of the Board of Directors.

     Section 3. CORPORATE CONTRACTS AND INSTRUMENTS; HOW EXECUTED. The Board of 
Directors, except as otherwise provided in these bylaws, may authorize any
officer or officers, agent or agents, to enter into any contract or execute any
instrument in the name of and on behalf of the corporation, and such authority
may be general or confined to specific instances; and, unless so authorized or
ratified by the Board of Directors or within the agency power of an officer, no
officer, agent or employee shall have any power or authority to bind the
corporation by any contract or engagement or to pledge its credit or to render
it liable for any purpose or to any amount.

     Section 4. CERTIFICATES FOR SHARES. A certificate or certificates for 
shares of the capital stock of the corporation shall be issued to each 
shareholder when any such shares are fully paid, and the Board of Directors may 
authorize the issuance of certificates or shares as partly paid provided that 
such certificates shall state the amount of the consideration to be paid
therefor and the amount paid thereon. All certificates shall be signed in the
name of the corporation by the Chairman of the Board or Vice Chairman of the
Board or the President or Vice President and by the Chief Financial Officer or
an Assistant Treasurer or the Secretary or any Assistant Secretary, certifying
the number of shares and the class or series of shares owned by the shareholder.
Any or all of the signatures on the certificate may be facsimile. In case any
officer, transfer agent or registrar who has signed or whose facsimile signature
has been placed upon a certificate shall have ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the corporation with the same effect as if such person were an officer,
transfer agent or registrar at the date of issue.

     Section 5. LOST CERTIFICATES. Except as hereinafter in this Section 5 
provided, no new certificates for shares shall be issued in lieu of an old 
certificate unless the latter is surrendered to the corporation and canceled at 
the same time. The Board of Directors may in case any share certificate or 
certificate for any other security is lost, stolen or destroyed, authorize the
issuance of a new certificate in lieu thereof, upon such terms and conditions as
the board may require, including provision for indemnification of the
corporation secured by a bond or other adequate security sufficient to protect 
the corporation against any claim that may be made against it, including any
expense or

<PAGE>
 
liability, on account of the alleged loss, theft or destruction of such 
certificate or the issuance of such new certificate.

     Section 6. REPRESENTATION OF SHARES OF OTHER CORPORATIONS. The Chairman of 
the Board, the President, or any Vice President, or any other person authorized 
by resolution of the Board of Directors by any of the foregoing designated 
officers, is authorized to vote on behalf of the corporation any and all shares 
of any other corporation or corporations, foreign or domestic, standing in the
name of the corporation. The authority herein granted to said officers to vote 
or represent on behalf of the corporation any and all shares held by the 
corporation in any other corporation or corporations may be exercised by any 
such officer in person or by any person authorized to do so by proxy duly
executed by said officer.

                                  ARTICLE IX

                                  AMENDMENTS

     Section 1. AMENDMENT BY SHAREHOLDERS. New bylaws may be adopted or these 
bylaws may be amended or repealed by the vote or written consent of holders of a
majority of the outstanding shares entitled to vote; provided, however, that if 
the articles of incorporation of the corporation set forth the number of 
authorized directors of the corporation, the authorized number of directors may 
be changed only by an amendment of the articles of incorporation.

     Section 2. AMENDMENT BY DIRECTORS. Subject to the rights of the
shareholders as provided in Section 1 of this Article IX, bylaws, other than a
bylaw or an amendment thereof changing the authorized number of directors, may
be adopted, amended or repealed by the Board of Directors.

                                   ARTICLE X

which are permissible under the California General Corporation Law. Any
provision (or portion thereof) in these bylaws which is not permissible under
the California General Law or is inconsistent with the articles of incorporation
of this corporation (as they may from time to time be amended

<PAGE>
 
and supplemented) is void, but the balance of these bylaws shall nevertheless be
valid and effective.

     Section 2.  CONSTRUCTION AND DEFINITIONS. Unless the context requires 
otherwise, the general provisions, rules of construction, and definitions in the
California General Corporation Law shall govern the construction of these

present signs a written waiver of notice, a consent to holding the meeting, or
an approval of the minutes thereof.  All such waivers, consents and approvals
shall be filed with the corporate records or made a part of the minutes of the
meeting.

     Section 10. Action Without Me.  Any action required or permitted to be
                 -----------------                                         
taken by the Board of Directors may be taken without a meeting, if all members
of the Board individually or 
<PAGE>
 
                                      -6-

collectively consent in writing to such action. Such written consent or consents
shall be filed with the minutes of the proceedings of the Board. Such action by
written consent shall have the same force and effect as a unanimous vote of such
directors.

     Section 11.  Removal.  The Board of Directors may declare vacant the office
                  -------                                                       
of a director who has been declared of unsound mind by an order of court or who
has been convicted of a felony.

     The entire Board of Directors or any individual director may be removed
from office without cause by a vote of shareholders holding a majority of the
outstanding shares entitled to vote at an election of directors; provided,
however, that unless the entire Board is removed, no individual director may be
removed when the votes cast against removal, or not consenting in writing to
such removal, would be sufficient to elect such director if voted cumulatively
at an election at which the same total number of votes cast were cast (or, if
such action is taken by written consent, all shares entitled to vote were voted)
and the entire number of directors authorized at the time of the director's most
recent election were then being elected.

     In the event an office of a director is so declared vacant or in case the
Board or any one or more directors be so removed, new directors may be elected
at the same meeting.

     Section 12.  Resignations.  Any director may resign effective upon giving
                  ------------                                                
notice to the Chairman of the Board, the President, the Secretary or the Board
of Directors of the Corporation, unless the notice specifies a later time for
the effectiveness of such resignation.  If the resignation is effective at a
future time, a successor may be elected to take office when the resignation
becomes effective.

     Section 13.  Vacancies.  Except for a vacancy created by the removal of a
                  ---------                                                   
director, all vacancies in the Board of Directors, whether caused by
resignation, death or otherwise, may be filled by a majority of the remaining
directors or, if the number of directors then in office is less than a quorum,
by (a) the unanimous written consent of the directors then in office, (b) the
affirmative vote of a majority of the directors then in office at a meeting held
pursuant to notice or waivers of notice complying with California Corporations
Code Section 307, or (c) a sole remaining director, and each director so elected
shall hold office until his successor is elected at annual, regular or special
meeting of the shareholders.  Vacancies created by the removal of a director may
be filled only by approval of the shareholders.  The shareholders may elect a
director at any time to fill any vacancy not filled by the directors.  Any such
election by written consent requires the consent of a majority of the
outstanding shares entitled to vote.

     Section 14.  Compensation.  No stated salary shall be paid directors, as
                  ------------                                               
such, for their services, but, by resolution of the Board of Directors, a fixed
sum and expenses of attendance, if any, may be allowed for attendance at each
regular or special meeting of such Board; provided that nothing herein contained
shall be construed to preclude any director from serving the Corporation in any
other capacity and receiving compensation therefor.  Members of special or
standing committees may be allowed like compensation for attending committee
meetings.

     Section 15. Committees.  The Board of Directors may, by resolution adopted
                 ----------                                                    
by a majority of the authorized number of directors, designate one or more
committees, each consisting of two or more directors, to serve at the pleasure
of the Board of Directors.  The Board of Directors may designate one or more
directors as alternate members of any committee, who may replace any absent
member at any meeting of the committee.  The appointment of members or alternate
members of a committee requires the vote of a majority of the authorized number
of directors.  Any such committee, to the extent provided in the resolution of
the Board of Directors, shall have all the authority of the Board of Directors
in the management of the business and affairs of the Corporation, except with
respect to (a) the approval of any action requiring shareholders' approval or
approval of the outstanding shares, (b) the filling of vacancies on the Board or
any committee, (c) the fixing of compensation of directors for serving on the
Board or any committee, (d) the adoption, amendment or repeal of Bylaws, (e) the
amendment or repeal of any resolution of the Board which by its express terms is
not so amendable or repealable, (f) a distribution to shareholders, except at a
rate or in a periodic amount or within a price range determined by the Board,
and (g) the appointment of other committees of the Board or the members thereof.

effect to any written certification, proxy or other authorization furnished by
the Depositary or impair, as between the Depositary and its Agent Members, the
operation of customary practices of the Depositary governing the exercise of the

          (iv)  In connection with any transfer of a portion of the beneficial
interest in a Global Security pursuant to subsection (e) of this Section to
beneficial owners who are required to hold Definitive Securities, the Security
Trustee shall reflect on its books and records the date and a decrease in the
principal amount of such Global Security in an amount equal to the principal
amount of the beneficial interest in the Global Security to be transferred, and
the Company shall execute, and the Trustee shall authenticate and deliver, one
or more Definitive Securities of like tenor and amount.

          (v)   In connection with the transfer of an entire Global Security to
beneficial owners pursuant to subsection (e) of this Section, such Global
Security shall be deemed to be surrendered to the Trustee for cancellation, and

each beneficial owner identified by the Depositary in exchange for its
beneficial interest in such Global Security, an equal aggregate principal amount
of Definitive Securities of authorized denominations.

                          ---------------------                         
pursuant to any applicable law or regulation, beneficial owners may obtain
Definitive Securities in exchange for their beneficial interests in a Global

unwilling or unable to continue as Depositary for such Global Security or the
Depositary ceases to be a clearing agency registered under the Exchange Act, at
a time when the Depositary is required to be so registered in order to act as
Depositary, and in each case a successor depositary is not appointed by the
Company within 90 days of such notice or, (ii) the Company executes and delivers
to the Trustee and Registrar an Officers' Certificate stating that such Global
Security shall be so exchangeable or (iii) an Event of Default has occurred and
is continuing and the Registrar has received a request from the Depositary.

          (f)  Any Definitive Security delivered in exchange for an interest in
a Global Security pursuant to Section 2.1(d)(iv) or (v) shall, except as
                              -------------------------

          (g)  The registered holder of a Global Security may grant proxies and
otherwise authorize any person, including Agent Members and persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Securities.

          SECTION II.2.  Execution and Authentication.  One Officer shall sign
                         ----------------------------                         
the Securities for the Company by manual or facsimile signature.  If an Officer
whose signature is on a Security no longer holds that office at the time the
Trustee authenticates the Security, the Security shall be valid nevertheless.

          A Security shall not be valid until an authorized signatory of the
Trustee manually authenticates the Security.  The signature of the Trustee on a
Security shall be conclusive evidence that such Security has been duly and
validly authenticated and issued under this Indenture.

          At any time and from time to time after the execution and delivery of
this Indenture, the Trustee shall authenticate and make available for delivery:
(1) Initial Securities for original issue on the Issue Date in an aggregate
principal amount of $150.0 million, (2) Exchange Securities for issue only in a
Registered Exchange Offer pursuant to the Registration Rights Agreement, and
only in exchange for Initial Securities of an equal principal amount, and (3)
additional series of notes which may be offered subsequent to the Issue Date
(the "Subsequent Series Securities") in an aggregate principal amount not to
exceed $100,000,000, in each case upon a written order of the Company signed by
two Officers or by an Officer and either an Assistant Treasurer or an Assistant
Secretary of the Company (the "Company Order").  Such Company Order shall
                               -------------                             
specify the amount of the Securities to be authenticated and the date on which
the original issue of Securities is to be authenticated and whether the
Securities are to be Initial Securities or Exchange Securities.  The aggregate
principal amount of notes which may be authenticated and delivered under this
Indenture is limited to $250.0 million outstanding except as provided in Section
                                                                         -------
2.9.  No Subsequent Series Securities may be authenticated and delivered in an

aggregate principal amount of less than $25,000,000.  All Securities issued on
the Issue Date and all Subsequent Series Securities shall be identical in all
respects other than issue dates, the date from which interest accrues and any
changes relating thereto.   Notwithstanding 
<PAGE>
 
                                                                              29

anything to the contrary contained in this Indenture, all notes issued under
this Indenture shall vote and consent together on all matters as one class and
no series of notes will have the right to vote or consent as a separate class on
any matter.

          The Trustee may appoint an agent (the "Authenticating Agent")
                                                 --------------------  
reasonably acceptable to the Company to authenticate the Securities.  Unless
limited by the terms of such appointment, any such Authenticating Agent may
authenticate Securities whenever the Trustee may do so.  Each reference in this
Indenture to authentication by the Trustee includes authentication by the
Authenticating Agent.

          In case the Company, pursuant to Article IV, shall be consolidated or
merged with or into any other Person or shall convey, transfer, lease or
otherwise dispose of its properties and assets substantially as an entirety to
any Person, and the successor Person resulting from such consolidation, or
surviving such merger, or into which the Company shall have been merged, or the
Person which shall have received a conveyance, transfer, lease or other
disposition as aforesaid, shall have executed an indenture supplemental hereto
with the Trustee pursuant to Article IV, any of the Securities authenticated or
delivered prior to such consolidation, merger, conveyance, transfer, lease or
other disposition may, from time to time, at the request of the successor
Person, be exchanged for other Securities executed in the name of the successor
Person with such changes in phraseology and form as may be appropriate, but
otherwise in substance of like tenor as the Securities surrendered for such
exchange and of like principal amount; and the Trustee, upon Company Order of
the successor Person, shall authenticate and deliver Securities as specified in
such order for the purpose of such exchange.  If Securities shall at any time be
authenticated and delivered in any new name of a successor Person pursuant to
this Section 2.2 in exchange or substitution for or upon registration of

transfer of any Securities, such successor Person, at the option of the Holders
but without expense to them, shall provide for the exchange of all Securities at
the time outstanding for Securities authenticated and delivered in such new
name.

in the Borough of Manhattan, The City of New York.  The Registrar shall keep a
register of the Securities and of their transfer and exchange (the "Note

additional paying agents.  The term "Paying Agent" includes any additional
paying agent.

          The Company shall enter into an appropriate agency agreement with any
Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall incorporate the terms of the TIA.  The agreement shall implement the
provisions of this Indenture that relate to such agent.  The Company shall
notify the Trustee of the name and address of each such agent.  If the Company
fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and
shall be entitled to appropriate compensation therefor pursuant to Section 7.7.
                                                                   -----------

require each Paying Agent (other than the Trustee) to agree in writing that such
Paying Agent shall hold in trust for the benefit of Securityholders or the
Trustee all money held by such Paying Agent for the payment of principal of or
interest on the Securities and shall notify the Trustee in writing of any
default by the Company or any Guarantor in making any such payment.  If the
Company or a Subsidiary acts as Paying Agent, it shall segregate the money held
by it as Paying Agent and hold it as a separate trust fund.  The Company at any
time may require a Paying Agent (other than the Trustee) to pay all money held
by it to the Trustee and to account for any funds disbursed by such Paying
Agent.  Upon complying with this Section, the Paying Agent (if other than the
Company or a Subsidiary) shall have no further liability for the money delivered
to the Trustee.  Upon any bankruptcy, reorganization or similar proceeding with
respect to the Company, the Trustee shall serve as Paying Agent for the
Securities.

interest payment date and at such other times as the Trustee may request in
writing, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of Securityholders.

          The undersigned represents and warrants to you that:

          1.   We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the

institutional "accredited investor" at least $250,000 principal amount of the
Securities, and we are acquiring the Securities not with a view to, or for offer
or sale in connection with, any distribution in violation of the Securities Act.
We have such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risk of our investment in the Securities
and we invest in or purchase securities similar to the Securities in the normal
course of our business.  We and any accounts for which we are acting are each
able to bear the economic risk of our or its investment.

          2.   We understand that the Securities have not been registered under
the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence.  We agree on our own behalf and on behalf
of any investor account for which we are purchasing Securities to offer, sell or
otherwise transfer such Securities prior to the date which is two years after
the later of the date of original issue and the last date on which the Company
or any affiliate of the Company was the owner of such Securities (or any
predecessor thereto) (the "Resale Restriction Termination Date") only (a) to the
Company, (b) pursuant to a registration statement which has been declared
effective under the Securities Act, (c) in a transaction complying with the
requirements of Rule 144A under the Securities Act, to a person we reasonably
believe is a qualified institutional buyer under Rule 144A (a "QIB") that
purchases for its own account or for the account of a QIB and to whom notice is
given that the transfer is being made in reliance on Rule 144A, (d) pursuant to
offers and sales that occur outside the United States within the meaning of
Regulation S under the Securities Act, (e) to an institutional "accredited
investor" within the meaning of Rule 501(a)(1), (2), (3) or (7) under the
Securities Act that is purchasing for its own account or for the account of such
an institutional "accredited investor," in each case in a minimum principal
amount of Securities of $250,000 or (f) pursuant to any other available
exemption from the registration requirements of the Securities Act, subject in
each of the foregoing cases to any requirement of law that the disposition of
our property or the property of such investor account or accounts be at all
times within our or their control and in compliance with any applicable state
securities laws.  The foregoing restrictions on resale will not apply subsequent
to the Resale Restriction Termination Date.  If any resale or other transfer of
the Securities is proposed to be made pursuant to clause (e) above prior to the
Resale Restriction Termination Date, the transferor shall deliver a letter from
the transferee substantially in the form of this letter to the Company and the
Trustee, which shall provide, among other things, that the transferee is an
institutional "accredited investor" (within the meaning of Rule 501(a)(1), (2),
(3) or (7) under the Securities Act) and that it is acquiring such Securities
for investment purposes and not for distribution in violation of the Securities
Act.  Each purchaser acknowledges that the Company and the Trustee reserve the
right prior to any offer, sale or other transfer prior to the Resale Termination
Date of the Securities pursuant to clauses (d), (e) or (f) above to require the
delivery of an opinion of counsel, certifications and/or other information
satisfactory to the Company and the Trustee.

               9 1/4% Senior Subordinated Notes due 2008 (the "Securities")
               ------------------------------------------------------------

Ladies and Gentlemen:

          In connection with our proposed sale of $________ aggregate principal
amount of the Securities, we confirm that such sale has been effected pursuant
to and in accordance with Regulation S under the United States Securities Act of
1933, as amended (the "Securities Act"), and, accordingly, we represent that:

          (a)  the offer of the Securities was not made to a person in the
     United States;

          (b)  either (i) at the time the buy order was originated, the
     transferee was outside the United States or we and any person acting on our
     behalf reasonably believed that the transferee was outside the United
     States or (ii) the transaction was executed in, on or through the
     facilities of a designated off-shore securities market and neither we nor
     any person acting on our behalf knows that the transaction has been pre-
     arranged with a buyer in the United States;

          (c)  no directed selling efforts have been made in the United States
     in contravention of the requirements of Rule 903(b) or Rule 904(b) of
     Regulation S, as applicable; and

          (d)  the transaction is not part of a plan or scheme to evade the
     registration requirements of the Securities Act.

          In addition, if the sale is made during a restricted period and the
provisions of Rule 903(c)(3) or Rule 904(c)(1) of Regulation S are applicable
thereto, we confirm that such

                                                                              36

sale has been made in accordance with the applicable provisions of Rule
903(c)(3) or Rule 904(c)(1), as the case may be.

          You and the Company are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested
party in any administrative or legal proceedings or official inquiry with
respect to the matters covered hereby.  Terms used in this certificate have the
meanings set forth in Regulation S.

          Very truly yours,

          [Name of Transferor]


          By:____________________________

          _______________________________
                Authorized Signature           Signature Medallion Guaranteed

          SECTION II.9.  Mutilated, Destroyed, Lost or Stolen Securities.  If a
                         -----------------------------------------------       
mutilated Security is surrendered to the Registrar or if the Holder of a
Security claims that the Security has been lost, destroyed or wrongfully taken,
the Company shall issue and the Trustee shall authenticate a replacement
Security if the requirements of Section 8-405 of the Uniform Commercial Code are
met and the Holder satisfies any other reasonable requirements of the Trustee.
If required by the Trustee or the Company, such Holder shall furnish an
indemnity bond sufficient in the judgment of the Company and the Trustee to
protect the Company, the Trustee, the Paying Agent, the Registrar and any co-
registrar from any loss which any of them may suffer if a Security is replaced,
and, in the absence of notice to the Company, any Subsidiary Guarantor or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and upon Company Order the Trustee shall authenticate and
make available for delivery, in exchange for any such mutilated Security or in
lieu of any such destroyed, lost or stolen Security, a new Security of like
tenor and principal amount, bearing a number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

          Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) in connection
therewith.

          Every new Security issued pursuant to this Section in lieu of any
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, any Subsidiary Guarantor (if
applicable) and any other obligor upon the Securities, 
<PAGE>
 
                                                                              37

whether or not the mutilated, destroyed, lost or stolen Security shall be at any
time enforceable by anyone, and shall be entitled to all benefits of this
Indenture equally and proportionately with any and all other Securities duly
issued hereunder.

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities.

          SECTION II.10.  Outstanding Securities.  Securities outstanding at any
                          ----------------------                                
time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancellation and those described in this
Section as not outstanding.  A Security ceases to be outstanding in the event
the Company or an Affiliate of the Company holds the Security provided, however,
that in determining whether the Trustee shall be protected in making a
determination whether the holders of the requisite principal amount of
outstanding Securities are present at a meeting of holders of Securities for
quorum purposes or have consented to or voted in favor of any request, demand,
authorization, direction, notice, consent, waiver, amendment or modification
hereunder, or relying upon any such quorum, consent or vote, only Securities
which the Trustee actually knows to be held by the Company or an Affiliate of
the Company shall not be considered outstanding.

          If a Security is replaced pursuant to Section 2.9, it ceases to be
                                                -----------                 
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a bona fide purchaser.

          If the Paying Agent segregates and holds in trust, in accordance with
this Indenture, on a redemption date or maturity date money sufficient to pay
all principal and interest payable on that date with respect to the Securities
(or portions thereof) to be redeemed or maturing, as the case may be, and the
Paying Agent is not prohibited from paying such money to the Securityholders on
that date pursuant to the terms of this Indenture, then on and after that date
such Securities (or portions thereof) cease to be outstanding and interest on
them ceases to accrue.

          SECTION II.11.  Temporary Securities.  Until definitive Securities are
                          --------------------                                  
ready for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities.  Temporary Securities shall be substantially in the form
of Definitive Securities but may have variations that the Company considers
appropriate for temporary Securities.  Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate Definitive Securities.  After
the preparation of Definitive Securities, the temporary Securities shall be
exchangeable for Definitive Securities upon surrender of the temporary
Securities at any office or agency maintained by the Company for that purpose
and such exchange shall be without charge to the Holder.  Upon surrender for
cancellation of any one or more temporary Securities, the Company shall execute,
and the Trustee shall authenticate and make available for delivery in exchange
therefor, one or more Definitive Securities representing an equal principal
amount of Securities.  Until so exchanged, the Holder of temporary Securities
shall in all respects be entitled to the same benefits under this Indenture as a
holder of Definitive Securities.

                                                                              38

          SECTION II.12.  Cancellation.  The Company at any time may deliver
                          ------------                                      
Securities to the Trustee for cancellation.  The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment.  The Trustee and no one else shall cancel and
return to the Company all Securities surrendered for registration of transfer,
exchange, payment or cancellation.  The Company may not issue new Securities to
replace Securities it has paid or delivered to the Trustee for cancellation for
any reason other than in connection with a transfer or exchange.

          SECTION II.13.  Payment of Interest; Defaulted Interest.  Interest on
                          ---------------------------------------              
any Security which is payable, and is punctually paid or duly provided for, on
any interest payment date shall be paid to the Person in whose name such
Security (or one or more predecessor Securities) is registered at the close of
business on the regular record date for such interest at the office or agency of
the Company maintained for such purpose pursuant to Section 2.3.
                                                    ----------- 

          Any interest on any Security which is payable, but is not paid when
the same becomes due and payable and such nonpayment continues for a period of
30 days shall forthwith cease to be payable to the Holder on the regular record
date by virtue of having been such Holder, and such defaulted interest and (to
the extent lawful) interest on such defaulted interest at the rate borne by the
Securities (such defaulted interest and interest thereon herein collectively
called "Defaulted Interest") shall be paid by the Company, at its election in
        ------------------                                                   
each case, as provided in clause (a) or (b) below:

          (a)  The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Securities (or their respective
     predecessor Securities) are registered at the close of business on a
     Special Record Date (as defined below) for the payment of such Defaulted
     Interest, which shall be fixed in the following manner.  The Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each Security and the date (not less than 30 days after such
     notice) of the proposed payment (the "Special Interest Payment Date"), and
                                           -----------------------------       
     at the same time the Company shall deposit with the Trustee an amount of
     money equal to the aggregate amount proposed to be paid in respect of such
     Defaulted Interest or shall make arrangements satisfactory to the Trustee
     for such deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this clause provided.  Thereupon the Trustee
     shall fix a record date (the "Special Record Date") for the payment of such
                                   -------------------                          
     Defaulted Interest which shall be not more than 15 days and not less than
     10 days prior to the Special Interest Payment Date and not less than 10
     days after the receipt by the Trustee of the notice of the proposed
     payment.  The Trustee shall promptly notify the Company of such Special
     Record Date, and in the name and at the expense of the Company, shall cause
     notice of the proposed payment of such Defaulted Interest and the Special
     Record Date and Special Interest Payment Date therefor to be given in the
     manner provided for in Section 13.2, not less than 10 days prior to such
                            ------------                                     
     Special Record Date.  Notice of the proposed payment of such Defaulted
     Interest and the Special Record Date and Special Interest Payment Date
     therefor having been so given, such Defaulted Interest shall be 
<PAGE>
 
                                                                              39

     paid on the Special Interest Payment Date to the Persons in whose names the
     Securities (or their respective Predecessor Securities) are registered at
     the close of business on such Special Record Date and shall no longer be
     payable pursuant to the following clause (b).

          (b)  The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Securities may be listed, and upon such
     notice as may be required by such exchange, if, after notice given by the
     Company to the Trustee of the proposed payment pursuant to this clause,
     such manner of payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

          SECTION II.14.  Computation of Interest.  Interest on the Securities
                          -----------------------                             
shall be computed on the basis of a 360-day year of twelve 30-day months.

          SECTION II.15.  CUSIP Numbers.  The Company in issuing the Securities
                          -------------                                        
may use "CUSIP" numbers (if then generally in use) and, if so, the Trustee shall
use "CUSIP" numbers in notices of redemption as a convenience to Holders;
provided, however, that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Securities or as
contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such CUSIP
numbers.
<PAGE>
 
                                                                              40

          In the event that the Company shall issue and the Trustee shall
authenticate any Subsequent Series Securities pursuant to Section 2.2, the
Company shall use its best efforts to obtain the same CUSIP number for such
Subsequent Series Securities as is printed on the Securities outstanding at such
time; provided, however, that if any series of Subsequent Series Securities is
      --------                                                                
determined, pursuant to an Opinion of Counsel, to be a different class of
security than the Securities outstanding at such time for federal income tax
purposes, the Company may obtain a CUSIP number for such series of Subsequent
Series Securities that is different from the CUSIP number printed on the
Securities then outstanding.


                                  ARTICLE III

                                   Covenants
                                   ---------

          SECTION III.1.  Payment of Securities.  The Company shall promptly pay
                          ---------------------                                 
the principal of and interest on the Securities on the dates and in the manner
provided in the Securities and in this Indenture.  Principal and interest shall
be considered paid on the date due if on such date the Trustee or the Paying
Agent holds in accordance with this Indenture money sufficient to pay all
principal and interest then due and the Trustee or the Paying Agent, as the case
may be, is not prohibited from paying such money to the Securityholders on that
date pursuant to the terms of this Indenture.

          The Company shall pay interest on overdue principal at the rate
specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

          Notwithstanding anything to the contrary contained in this Indenture,
the Company may, to the extent it is required to do so by law, deduct or
withhold income or other similar taxes imposed by the United States of America
from principal or interest payments hereunder.

          SECTION III.2.  SEC Reports and Available Information.
                          -------------------------------------  
Notwithstanding that the Company may not be subject to the reporting
requirements of Section 13(a) or 15(d) of the Exchange Act, to the extent
permitted by the Exchange Act, the Company will file with the SEC, and provide,
within 15 days after the Company is or would be required to file the same with
the SEC, the Trustee and the holders of Securities with the annual reports and
the information, documents and other reports (or copies of such portions of any
of the foregoing as the SEC may, by rules and regulations prescribe), that are
specified in Sections 13 and 15(d) of the Exchange Act. In the event that the
Company is not permitted to file such reports, documents and information with
the SEC pursuant to the Exchange Act, the Company will nevertheless deliver such
Exchange Act information to the Trustee and the holders of the Securities as if
the Company were subject to the reporting requirements of Section 13 or 15(d) of
the Exchange Act.  In addition, for so long as any of the Securities remain
outstanding the Company shall make available to any prospective purchaser of the
Securities or beneficial owner of the Securities in connection with any sale
thereof the information required by Rule 144A(d)(4) under the 
<PAGE>
 
                                                                              41

Securities Act. The Company shall also comply with the other provisions of TIA
(S) 314(a). Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

          SECTION III.3.  Limitation on Indebtedness.  (a)  The Company shall
                          --------------------------                         
not, and shall not permit any of its Restricted Subsidiaries to, Incur any
Indebtedness; provided, however, that the Company and its Restricted
Subsidiaries which are Subsidiary Guarantors may Incur Indebtedness if on the
date thereof, after giving pro forma effect to the incurrence of such
Indebtedness, the Leverage Ratio for the Company and its Restricted Subsidiaries
is less than (i) 6.50 to 1.00, if such Indebtedness is Incurred on or prior to
the second anniversary of the Issue Date, and (ii) 6.00 to 1.00, if such
Indebtedness is Incurred thereafter.

          (b)  Notwithstanding the foregoing paragraph (a) the Company and its
Restricted Subsidiaries may Incur the following Indebtedness: (i) Indebtedness
Incurred pursuant to the Senior Credit Agreement of (x) up to $210.0 million in
term loan borrowings outstanding at any time and (y) up to $60.0 million in
revolving credit borrowings outstanding at any time; (ii) the Subsidiary
Guarantees and Guarantees of Indebtedness Incurred pursuant to paragraph (a) or
clause (i) of this paragraph (b); (iii) Indebtedness of the Company owing to and
held by any Wholly-Owned Subsidiary or Indebtedness of a Restricted Subsidiary
owing to and held by the Company or any Wholly-Owned Subsidiary; provided,
however, that any subsequent issuance or transfer of any Capital Stock or any
other event which results in any such Wholly-Owned Subsidiary ceasing to be a
Wholly-Owned Subsidiary or any subsequent transfer of any such Indebtedness
(except to the Company or a Wholly-Owned Subsidiary) shall be deemed, in each
case, to constitute the Incurrence of such Indebtedness by the issuer thereof;
(iv) Indebtedness represented by (x) $150.0 million aggregate principal amount
of the Securities, (y) any Indebtedness (other than the Indebtedness described
in clauses (i), (ii) and (iii)) outstanding on the Issue Date and (z) any
Refinancing Indebtedness Incurred in respect of any Indebtedness described in
this clause (iv) or clause (v) or Incurred pursuant to paragraph (a) above; (v)
Indebtedness of a Restricted Subsidiary Incurred and outstanding on the date on
which such Restricted Subsidiary was acquired by the Company; provided, however,
that at the time such Restricted Subsidiary is acquired by the Company, the
Company would have been able to Incur $1.00 of additional Indebtedness pursuant
to paragraph (a) above after giving effect to the Incurrence of such
Indebtedness pursuant to this clause (v); (vi) Indebtedness under Currency
Agreements and Interest Rate Agreements; provided, however, that in the case of
Currency Agreements and Interest Rate Agreements, such Currency Agreements and
Interest Rate Agreements are entered into for bona fide hedging purposes of the
Company or its Restricted Subsidiaries (as determined in good faith by the Board
of Directors or senior management of the Company) and correspond in terms of
notional amount, duration, currencies and interest rates, as applicable, to
Indebtedness of the Company or its Restricted Subsidiaries Incurred without
violation of this Indenture or to business transactions of the Company or its
Restricted Subsidiaries on customary terms entered into in the ordinary course
of business; and (vii) Indebtedness (other than Indebtedness described in
clauses (i) - (vi)) in a principal amount 
<PAGE>
 
                                                                              42

which, when taken together with the principal amount of all other Indebtedness
Incurred pursuant to this clause (vii) and then outstanding, will not exceed
$20.0 million.

          (c)  Neither the Company nor any Restricted Subsidiary shall Incur any
Indebtedness under Section 3.3(b) if the proceeds thereof are used, directly or
                   --------------

provisions, the Company and its Restricted Subsidiaries will not be required to
apply any Net Available Cash in accordance herewith except to the extent that
the aggregate Net Available Cash from all Asset Dispositions which are not
applied in accordance with this covenant exceed $1.0 million. Any Net Available

of the Company and the release of the Company or such Restricted Subsidiary from
all liability on such Senior Indebtedness or Indebtedness in connection with
such Asset Disposition (in which case the Company will, without further action,
be deemed to have applied such assumed Indebtedness in accordance with clause
(i) of the preceding paragraph); (y) securities received by the Company or any
Restricted Subsidiary of the Company from the transferee that are promptly
converted by the Company or such Restricted Subsidiary into cash; and (z) the
fair market value, as determined by the Board of Directors of the Company in
good faith, of any Designated Noncash Consideration received by the Company or
any of its Restricted Subsidiaries in any Asset Disposition, taken together with
the fair market value, as determined by the Board of Directors of the Company in
good faith, of all other Designated Noncash Consideration received pursuant to
this clause (z) that is at that time outstanding, not to exceed $25.0 million at
the time of the receipt of such Designated Noncash Consideration (with the fair
market value of each item of Designated Noncash Consideration being measured at
the time received and without giving effect to subsequent changes in value), in
which case such Designated Noncash Consideration shall not constitute Net
Available Cash.

the product of such Excess Proceeds multiplied by a fraction, the numerator of
which is the outstanding principal amount of the Securities and the denominator
of which is the sum of the outstanding principal amount of the Securities and
the outstanding principal amount (or accreted value, as the case may be) of the
Pari Passu Notes at a purchase price of 100% of the principal amount thereof
plus accrued and unpaid interest, if any, to the date of purchase and (B) the
Company will make an offer to purchase any Pari Passu Notes (a "Pari Passu

as the case may be) thereof plus accrued and unpaid interest, if any, to the
date of purchase in accordance with the procedures (including prorating in the
event of oversubscription) set forth in the documentation governing such Pari
Passu Notes with respect to the Pari Passu Offer. If the aggregate purchase
price of the Notes and Pari Passu Notes tendered pursuant to the Offer and the
Pari Passu Offer is less than the Excess Proceeds, the remaining Excess Proceeds
will be available to the Company to fund other corporate purposes not otherwise
prohibited by this Indenture.

          (c)  (1)  Promptly, and in any event within 10 days after the Company
is required to make an Offer, the Company will deliver to the Trustee and send,
by first-class mail to each Holder, a written notice stating that the Holder may
elect to have his Securities purchased by the Company either in whole or in part
(subject to prorating as hereinafter described in the event the Offer is
oversubscribed) in integral multiples of $1,000 of principal amount, at the
applicable purchase price.  The notice shall specify a purchase date not less
than 30 days nor more than 60 days after the date of such notice (the "Purchase
                                                                       --------

the Company shall deliver to the Trustee for cancellation the Securities or
portions thereof which have been properly tendered to and are to be accepted by
the Company.  The Trustee shall, on the Purchase Date, mail or deliver payment
to each tendering Holder in the amount of the purchase price of the Securities
tendered by such Holder to the extent such funds are available to the Trustee.

          (3)  Holders electing to have a Security purchased will be required to
surrender the Security, with an appropriate form entitled "Option of Holder to
Elect Purchase" duly completed, to the Company at the address specified in the

Trustee or the Company receives, not later than one Business Day prior to the
expiration of the Offer Period, a facsimile transmission or overnight mail from
such Holder setting forth the name of such Holder, the principal amount of the
Security or Securities which were delivered for purchase by such Holder and a
statement that such Holder is withdrawing his election to have such Security or
Securities purchased. If at the expiration of the Offer Period the aggregate
principal amount of Securities surrendered by Holders exceeds the Offer Amount,
the Company shall select the Securities to be purchased on a pro rata basis
(with such adjustments as may be deemed appropriate by the Company so that only
Securities in denominations of $1,000, or integral multiples thereof, shall be
purchased). Holders whose Securities are purchased only in part will be issued
new Securities equal in principal amount to the unpurchased portion of the
Securities surrendered.

          (d)  The Company will comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the repurchase of Securities pursuant to this

regulations conflict with provisions of this Section 3.7, the Company will

that this clause (iii) will not apply to any Affiliate Transaction with any
joint venture or similar entity in which the Permitted Holders do not have any
direct or indirect interests other than the interests of the Company and its

prompt written notice to the Trustee of any such designation or rescission and
any change in the location of any such other office or agency.

Restricted Subsidiary; provided, however, that the Company shall not be required

Restricted Subsidiary; provided, however, that the Company shall not be required
to pay or discharge or cause to be paid or discharged any such tax, assessment,
charge or claim whose amount, applicability or validity is being contested in
good faith by appropriate proceedings and for which appropriate reserves, if
necessary (in the good faith judgment of management of the Company), are being
maintained in accordance with GAAP or where the failure to effect such payment
will not be disadvantageous to the Holders.

          SECTION III.18.  Compliance Certificate.  The Company shall deliver to

                           Redemption of Securities
                           ------------------------

          SECTION V.1. Optional Redemption.  The Securities may or shall, as the

case may be, be redeemed, as a whole or from time to time in part, subject to
the conditions and at the Redemption Prices specified in the form of Securities
set forth in Exhibits A and B hereto, which are hereby incorporated by reference
             ----------------

the redemption date.

          SECTION V.2. Applicability of Article.  Redemption of Securities at
                       ------------------------                              
the election of the Company or otherwise, as permitted or required by any
provision of this Indenture, shall be made in accordance with such provision and
this Article.

          SECTION V.3. Election to Redeem; Notice to Trustee.  The election of
                       -------------------------------------                  
the Company to redeem any Securities pursuant to Section 5.1 shall be evidenced
                                                 -----------                   
by a Board Resolution.  In case of any redemption at the election of the
Company, the Company shall, upon not less than 45 and not more than 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and
of the principal amount of Securities to be redeemed and shall deliver to the
Trustee such documentation and records as shall enable the Trustee to select the
Securities to be redeemed pursuant to Section 5.4.
                                      ----------- 

          SECTION V.4. Selection by Trustee of Securities to Be Redeemed.  If
                       -------------------------------------------------     
less than all the Securities are to be redeemed at any time pursuant to an
optional redemption, the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
outstanding Securities not previously called for redemption, in compliance with
the requirements of the principal securities exchange, if any, on which such
Securities are listed, or, if such Securities are not so listed, on a pro rata
basis, by lot or by such other method as the Trustee shall deem fair and
appropriate (and in such manner as complies with applicable legal requirements)
and which may provide for the selection for redemption of portions of the
principal of the Securities; provided, however, that no such partial redemption
shall reduce the portion of the principal amount of a Security not redeemed to
less than $1,000.

          The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to redemption of Securities shall relate, in
the case of any Security redeemed or to be redeemed only in part, to the portion
of the principal amount of such Security which has been or is to be redeemed.

Trustee, at least 45 days prior to the Redemption Date, an Officers' Certificate
requesting that the Trustee give such notice and setting forth the information

     Redemption Date, upon surrender of such Security, the holder will receive,
     without charge, a new Security or Securities of authorized denominations
     for the principal amount thereof remaining unredeemed,

               (5)  that on the Redemption Date the Redemption Price (and
     accrued interest, if any, to the Redemption Date payable as provided in
     Section 5.7) will become due and payable upon each such Security, or the

     portion thereof, to be redeemed, and, unless the Company defaults in making

               (10) the paragraph of the Securities pursuant to which the
     Securities are to be redeemed.

          SECTION V.6.  Deposit of Redemption Price.  Prior to any Redemption
                        ---------------------------                          
Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 2.4) an amount of money sufficient to pay the Redemption
            -----------

Redemption Date, become due and payable at the Redemption Price therein
specified (together with accrued interest, if any, to the Redemption Date), and
from and after such date (unless the Company shall default in the payment of the
Redemption Price and accrued interest) such Securities shall cease to bear
interest.  Upon surrender of any such Security for redemption in accordance with
said notice, such Security shall be paid by the Company at the Redemption Price,
together with accrued interest, if any, to the Redemption Date; provided,
however, that installments of interest whose Stated Maturity is on or prior to
the Redemption Date shall be payable to the Holders of such Securities, or one
or more Predecessor Securities, registered as such at the close of business on
the relevant Regular Record Date or Special Record Date, as the case may be,
according to their terms and the provisions of Section 2.13.
                                               ------------ 

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate borne by the
Securities.

          SECTION V.8.  Securities Redeemed in Part.
                        --------------------------- 

          Any Security which is to be redeemed only in part (pursuant to the
provisions of this Article) shall be surrendered at the office or agency of the
Company maintained for such purpose pursuant to Section 3.15 (with, if the

available for delivery to the Holder of such Security at the expense of the
Company, a new Security or Securities, of any authorized denomination as
requested by such Holder, in an aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so

     by Article X of this Indenture;

          (3)  the Company fails to comply with Article IV of this Indenture;

     the notice specified below;

          (5)  the Company defaults in the performance of or a breach by the
     Company of any other covenant or agreement in this Indenture or under the

                    (D)  makes a general assignment for the benefit of its
     creditors; or takes any comparable action under any foreign laws relating
     to insolvency;

          (8)  a court of competent jurisdiction enters an order or decree under

          (9)  any judgment or decree for the payment of money in excess of $5.0
     million or its foreign currency equivalent at the time is rendered against
     the Company or a Significant Subsidiary if such judgment or decree remains

          The foregoing will constitute Events of Default whatever the reason

means any receiver, trustee, assignee, liquidator, custodian or similar official
under any Bankruptcy Law.

          Notwithstanding the foregoing, a Default under clause (4) or (5) of
this Section 6.1 will not constitute an Event of Default until the Trustee or
     -----------                                                             
the Holders of more than 25% in principal amount of the outstanding Securities
notify the Company of the Default and the Company does not cure such Default
within the time specified in said clause (4) or (5) after receipt of such
notice.  Such notice must specify the Default, demand that it be remedied and
state that such notice is a "Notice of Default".

          The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Default or Event of Default under clauses (3), (4), (5), (6), (9) or (10) of
this Section 6.1.

Event of Default specified in Section 6.1(7) or (8) with respect to the Company)

occurs and is continuing, the Trustee by notice to the Company, or the Holders
of at least 25% in outstanding principal amount of the Securities by notice to
the Company and the Trustee, may, and the Trustee at the request of such Holders
shall, declare the principal of, premium, if any, and accrued but unpaid
interest on all the Securities to be due and payable.  Upon such a declaration,
such principal, premium and interest shall, subject to Section 10.4 of this
                                                       ------------        
Indenture, be immediately due and payable.  In the event of a declaration of
acceleration because an Event of Default set forth in Section 6.1(6) above has
                                                      --------------          
occurred and is continuing, such declaration of acceleration shall be
automatically rescinded and annulled if the event of default or payment default
triggering such Event of Default pursuant to Section 6.1(6) shall be remedied or
                                             --------------                     
cured by the Company and/or the relevant Significant Subsidiaries or waived by
the holders of the relevant Indebtedness within 60 days after the declaration of
acceleration with respect thereto.  If an Event of Default specified in Section
                                                                        -------
6.1(7) or (8) with respect to the Company occurs, the principal of, premium and
- ------    ---                                                                  
accrued and unpaid interest on all the Securities will become and be immediately
due and payable without any declaration or other act on the part of the Trustee
or any Holders.  The Holders of a majority in principal amount of the Securities
by notice to the Trustee may waive all past defaults (except with respect to
nonpayment of principal, premium or interest) and rescind an acceleration with
respect to the Securities and its consequences if (i) the rescission would not
conflict with any judgment or decree of a court of competent jurisdiction and
(ii) all existing Events of Default, other than the nonpayment of principal or
interest that has become due solely because of such acceleration, have been
cured or waived.  No such rescission shall affect any subsequent Default or
Event of Default or impair any right consequent thereto.

          SECTION VI.3.  Other Remedies.  If an Event of Default occurs and is
                         --------------                                       
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.  No remedy is
exclusive of any other remedy.  All available remedies are cumulative.

          SECTION VI.4.  Waiver of Past Defaults.  The Holders of a majority in
                         -----------------------                               
principal amount of the Securities by notice to the Trustee may waive an
existing Default or Event of Default and its consequences except (i) a Default
or Event of Default in the payment of the principal of or interest on a Security
or (ii) a Default or Event of Default in respect of a provision

                                                                              61

that under Section 9.2 cannot be amended without the consent of each
           -----------
Securityholder affected. When a Default or Event of Default is waived, it is
deemed cured, but no such waiver shall extend to any subsequent or other Default
or Event of Default or impair any consequent right.

          SECTION VI.5.  Control by Majority.  The Holders of a majority in
                         -------------------                               
principal amount of the Securities may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee.  However, the Trustee
may refuse to follow any direction that conflicts with law or this Indenture or,
subject to Sections 7.1 and 7.2, that the Trustee determines is unduly
           --------------------                                       
prejudicial to the rights of other Securityholders or would involve the Trustee
in personal liability; provided, however, that the Trustee may take any other
action deemed proper by the Trustee that is not inconsistent with such
direction.  Prior to taking any action hereunder, the Trustee shall be entitled
to indemnification satisfactory to it in its sole discretion against all losses
and expenses caused by taking or not taking such action.

          SECTION VI.6.  Limitation on Suits.  A Securityholder may not pursue
                         -------------------                                  
any remedy with respect to this Indenture or the Securities unless:

          (1)  the Holder gives to the Trustee written notice stating that an
     Event of Default is continuing;

          (2)  the Holders of at least 25% in outstanding principal amount of
     the Securities make a request to the Trustee to pursue the remedy;

          (3)  such Holder or Holders offer to the Trustee reasonable security
     or indemnity against any loss, liability or expense (including reasonable
     attorneys' fees and expenses);

          (4)  the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer of security or indemnity; and

          (5)  the Holders of a majority in principal amount of the Securities
     do not give the Trustee a direction inconsistent with the request during
     such 60-day period.

          Subject to certain restrictions, the holders of a majority in
principal amount of the outstanding Securities are given the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or of exercising any trust or power conferred on the Trustee. The
Trustee, however, may refuse to follow any direction that conflicts with law or
the Indenture or that the Trustee determines is unduly prejudicial to the rights
of any other holder or that would involve the Trustee in personal liability.
Prior to taking any action under the Indenture, the Trustee shall be entitled to
indemnification satisfactory to it in its sole discretion against all losses and
expenses caused by taking or not taking such action.

occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the conduct of such Person's own affairs.

          (b)  Except during the continuance of an Event of Default:

          (1)  the Trustee undertakes to perform such duties and only such
     duties as are specifically set forth in this Indenture and no implied
     covenants or obligations shall be read into this Indenture against the
     Trustee; and

          (2)  in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture.  However,
     in the case of any such certificates or opinions which by any provisions
     hereof are specifically required to be furnished to the Trustee, the
     Trustee shall examine such certificates and opinions to determine whether
     or not they conform to the requirements of this Indenture (but need not
     confirm or investigate the accuracy of mathematical calculations or other
     facts stated therein).

     Section;

     takes or omits to take in good faith in accordance with a direction

expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers, if it shall have reasonable grounds to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

          (h)  Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section and to the provisions of the TIA.

demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

          (j)  The Trustee shall be under no obligation to exercise any of the
rights or powers vested in it by this Indenture at the request or direction of
any of the Holders unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses (including
reasonable attorneys' fees and expenses) and liabilities that might be incurred
by it in compliance with such request or direction.

          SECTION VII.2.  Rights of Trustee.  Subject to Section 7.1, (a)  The
                          -----------------              -----------          
Trustee may rely on any document believed by it to be genuine and to have been
signed or presented by the proper person.  The Trustee need not investigate any
fact or matter stated in the document.

          (b)  Before the Trustee acts or refrains from acting, it may require
an Officers' Certificate or an Opinion of Counsel.  The Trustee shall not be

advice or opinion of counsel with respect to legal matters relating to this
Indenture and the Securities shall be full and complete authorization and

                          ----------------------------                     
individual or any other capacity may become the owner or pledgee of Securities

it would have if it were not Trustee.  Any Paying Agent, Registrar, co-registrar
or co-paying agent may do the same with like rights.  However, the Trustee must
comply with Sections 7.10 and 7.11.
            -------------     ---- 

          SECTION VII.4.  Trustee's Disclaimer.  The Trustee shall not be

connection with the sale of the Securities or in the Securities other than the
Trustee's certificate of authentication.

          SECTION VII.5.  Notice of Defaults.  If a Default or Event of Default
                          ------------------                                   
occurs and is continuing and if a Trust Officer has actual knowledge thereof,
the Trustee shall mail to each Securityholder notice of the Default or Event of
Default within 90 days after it occurs.  Except in the case of a Default or
Event of Default in payment of principal of, premium (if any), or interest on
any Security (including payments pursuant to the optional redemption or required
repurchase provisions of such Security, if any), the Trustee may withhold the
notice if and so long as its board of directors, a committee of its board of
directors or a committee of its Trust Officers in good faith determines that
withholding the notice is in the interests of Securityholders.

          SECTION VII.6.  Reports by Trustee to Holders.  As promptly as
                          -----------------------------                 
practicable after each April 15 beginning with the April 15 following the date
of this Indenture, and in any event prior to June 15 in each year, the Trustee
shall mail to each Securityholder a brief report dated as of such April 15 that
complies with TIA (S) 313(a).  The Trustee also shall comply with TIA (S)
313(b).  The Trustee shall also transmit by mail all reports required by TIA (S)
313(c).

          A copy of each report at the time of its mailing to Securityholders
shall be filed with the SEC and each stock exchange (if any) on which the
Securities are listed.  The Company agrees to notify promptly the Trustee
whenever the Securities become listed on any stock exchange and of any delisting
thereof.

          SECTION VII.7.  Compensation and Indemnity.  The Company shall pay to
                          --------------------------                           
the Trustee from time to time reasonable compensation for its acceptance of this
Indenture and services hereunder as the Company and the Trustee shall from time
to time agree in writing.  The Trustee's compensation shall not be limited by
any law on compensation of a trustee of an express trust.  The Company shall
reimburse the Trustee upon request for all reasonable out-of-pocket expenses
incurred or made by it, including costs of collection, costs of preparing and
reviewing reports, certificates and other documents, costs of preparation and
mailing of notices to Securityholders and reasonable costs of counsel retained
by the Trustee in connection with the delivery of an Opinion of Counsel or
otherwise, in addition to the compensation for its services.  Such expenses

advances of the Trustee's agents, counsel, accountants and experts.  The Company

indemnify the Trustee against any and all loss, liability or expense (including
reasonable attorneys' fees and expenses) incurred by it without negligence or
bad faith on its part in connection with the administration of this trust and
the performance of its duties hereunder, including the costs and expenses of
enforcing this Indenture (including this Section 7.7) and of defending itself
                                         -----------        
against any claims (whether asserted by any Securityholder, the Company or
otherwise). The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity. Failure by the Trustee to so notify the Company shall not
relieve the Company of its obligations hereunder. The Company shall defend the
claim and the Trustee may have separate counsel and the Company shall pay the
fees and expenses of such counsel provided that the Company shall not be
required to pay such fees and expenses if it assumes the Trustee's defense, and,
in the reasonable judgement of outside counsel to the Trustee, there is no
conflict of interest between the Company and the Trustee in connection with such
defense. The Company need not reimburse any expense or indemnify against any
loss, liability or expense incurred by the Trustee through the Trustee's own
wilful misconduct, negligence or bad faith.

          To secure the Company's payment obligations in this Section, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Securities.  The Trustee's right to
receive payment of any amounts due under this Section 7.7 shall not be
                                              -----------             
subordinate to any other liability or indebtedness of the Company.

          The Company's payment obligations pursuant to this Section shall
survive the discharge of this Indenture.  When the Trustee incurs expenses after
the occurrence of a Default specified in Section 6.1(7) or (8) with respect to
                                         --------------    ---                
the Company, the expenses are intended to constitute expenses of administration
under any Bankruptcy Law.

          SECTION VII.8.  Replacement of Trustee.  The Trustee may resign at any
                          ----------------------                                
time by so notifying the Company.  The Holders of a majority in principal amount
of the Securities may remove the Trustee by so notifying the Trustee and may
appoint a successor Trustee.  The Company shall remove the Trustee if:

          (1)  the Trustee fails to comply with Section 7.10;
                                                ------------ 

          (2)  the Trustee is adjudged bankrupt or insolvent;

          (3)  a receiver or other public officer takes charge of the Trustee or
     its property; or

          (4)  the Trustee otherwise becomes incapable of acting.

          If the Trustee resigns or is removed by the Company or by the Holders
of a majority in principal amount of the Securities and such Holders do not
reasonably promptly appoint a successor Trustee, or if a vacancy exists in the
office of the Trustee for any reason (the Trustee in such event being referred
to herein as the retiring Trustee), the Company shall promptly appoint a
successor Trustee.

                                                                              67

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company.  Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture.  The successor Trustee shall mail a notice of its
succession to Securityholders.  The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.7.
                ----------- 

          If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee or the Holders of
10% in principal amount of the Securities may petition, at the Company's
expense, any court of competent jurisdiction for the appointment of a successor
Trustee.

          If the Trustee fails to comply with Section 7.10, any Securityholder
                                              ------------                    
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

          Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 7.7 shall continue for the
                                         -----------                       
benefit of the retiring Trustee.

          SECTION VII.9.  Successor Trustee by Merger.  If the Trustee
                          ---------------------------                 
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

          In case at the time such successor or successors by merger, conversion
or consolidation to the Trustee shall succeed to the trusts created by this
Indenture, any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have.

          SECTION VII.10. Eligibility; Disqualification.  The Trustee shall at
                          -----------------------------                       
all times satisfy the requirements of TIA (S) 310(a).  The Trustee shall have a
combined capital and surplus of at least $100 million as set forth in its most
recent published annual report of condition.  The Trustee shall comply with TIA
(S) 310(b); provided, however, that there shall be excluded from the operation
of TIA (S) 310(b)(1) any indenture or indentures under which other securities or
certificates of interest or participation in other securities of the Company are
outstanding if the requirements for such exclusion set forth in TIA (S)
310(b)(1) are met.

          SECTION VII.11. Preferential Collection of Claims Against Company.

in respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document and such omission to comply
shall no longer constitute a Default or an Event of Default under Section 6.1(3)
                                                                  --------------

    ------   --------------------------                                      
remainder of this Indenture and the Securities shall be unaffected thereby.  The
Company may exercise its legal defeasance option notwithstanding its prior
exercise of its covenant defeasance option.  If the Company exercises its
covenant defeasance option, the Company may, by written notice to the Trustee
prior to the delivery of the Opinion of Counsel referred to in Section 8.2(8),
                                                               -------------- 
elect to have any Subsidiary Guarantees in effect at such time terminate.

          If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of any event that, in the absence of
such legal defeasance, would have constituted an Event of Default, and the Note
Guarantees in effect at such time shall terminate.  If the Company exercises its
covenant defeasance option, the events specified in Sections 6.1(4), 6.1(6),

occurrence of any such event or because of the failure of the Company to comply
with Sections 4.1(iii).
     ----------------- 

          Upon satisfaction of the conditions set forth herein and upon request
of the Company, the Trustee shall acknowledge in writing the discharge of those
obligations that the Company terminates.

          (c)  Notwithstanding the provisions of Sections 8.1(a) and (b), the

survive.

          SECTION VIII.2.  Conditions to Defeasance.  The Company may exercise
                           ------------------------                           
its legal defeasance option or its covenant defeasance option only if:

          (1)  the Company irrevocably deposits in trust with the Trustee for
     the benefit of the Holders money in U.S. dollars or U.S. Government
     Obligations or a combination thereof for the payment of principal of and
     interest on the Securities to maturity or redemption, as the case may be;

          (2)  the Company delivers to the Trustee a certificate from a
     nationally recognized firm of independent accountants expressing their
     opinion that the payments of principal and interest when due and without
     reinvestment on the deposited U.S. Government Obligations plus any
     deposited money without investment will provide cash at such times and in
     such amounts as will be sufficient to pay principal and interest when due
     on all the Securities to maturity;

          (3)  no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default with respect to the Indenture resulting from the incurrence of
     Indebtedness, all or a portion of which will be used to defease the
     Securities concurrently with such incurrence);

          (4)  such legal defeasance or covenant defeasance shall not result in
     a breach or violation of, or constitute a Default under, this Indenture or
     any other material agreement or instrument to which the Company or any of
     its Subsidiaries is a party or by which the Company or any of its
     Subsidiaries is bound;

          (5)  the Company shall have delivered to the Trustee an Opinion of
     Counsel to the effect that (A) the Securities and (B) assuming no
     intervening bankruptcy of the Company between the date of deposit and the
     91st day following the deposit and that no Holder of the Securities is an
     insider of the Company, after 91st day following the deposit, the trust
     funds will not be subject to the effect of any applicable bankruptcy,
     insolvency, reorganization or similar laws affecting creditors' right
     generally;

                                                                              70

          (6)  the deposit does not constitute a default under any other
     agreement binding on the Company and is not prohibited by Article X;

          (7)  the Company delivers to the Trustee an Opinion of Counsel to the
     effect that the trust resulting from the deposit does not constitute, or is
     qualified as, a regulated investment company under the Investment Company
     Act of 1940;

          (8)  in the case of the legal defeasance option, the Company shall
     have delivered to the Trustee an Opinion of Counsel stating that (i) the
     Company has received from, or there has been published by, the Internal
     Revenue Service a ruling, or (ii) since the date of this Indenture there
     has been a change in the applicable federal income tax law, in either case
     to the effect that, and based thereon such Opinion of Counsel shall confirm
     that, the Securityholders will not recognize income, gain or loss for
     federal income tax purposes as a result of such defeasance and will be
     subject to federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such legal defeasance had
     not occurred;

          (9)  in the case of the covenant defeasance option, the Company shall
     have delivered to the Trustee an Opinion of Counsel in the United States to
     the effect that the Securityholders will not recognize income, gain or loss
     for federal income tax purposes as a result of such covenant defeasance and
     will be subject to federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such covenant
     defeasance had not occurred; and

          (10) the Company delivers to the Trustee an Officers' Certificate and
     an Opinion of Counsel, each stating that all conditions precedent to the
     defeasance and discharge of the Securities and this Indenture as
     contemplated by this Article VIII have been complied with.

          SECTION VIII.3.  Application of Trust Money.  The Trustee shall hold
                           --------------------------                         
in trust money or U.S. Government Obligations deposited with it pursuant to this
Article VIII.  It shall apply the deposited money and the money from U.S.
Government Obligations through the Paying Agent and in accordance with this
Indenture to the payment of principal of and interest on the Securities.  Money
and securities so held in trust are not subject to Article X.

          SECTION VIII.4.  Repayment to Company.  The Trustee and the Paying
                           --------------------                             
Agent shall promptly turn over to the Company upon request any excess money or
securities held by them upon payment of all the obligations under this
Indenture.

          Subject to any applicable abandoned property law, the Trustee and the
Paying Agent shall pay to the Company upon request any money held by them for
the payment of principal of or interest on the Securities that remains unclaimed
for two years, and, thereafter, Securityholders entitled to the money must look
to the Company for payment as general creditors.

          SECTION VIII.5.  Indemnity for U.S. Government Obligations.  The
                           -----------------------------------------      
Company shall pay and shall indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against deposited U.S. Government Obligations or
the principal and interest received on such U.S. Government Obligations.

          SECTION VIII.6.  Reinstatement.  If the Trustee or Paying Agent is
                           -------------                                    
unable to apply any money or U.S. Government Obligations in accordance with this
Article VIII by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the obligations of the Company under
this Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article VIII until such time as the
Trustee or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article VIII; provided, however, that, if
the Company has made any payment of interest on or principal of any Securities
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Securities to receive such payment from the
money or U.S. Government Obligations held by the Trustee or Paying Agent.

                                  Amendments
                                  ----------

          SECTION IX.1.  Without Consent of Holders.  The Company, the
                         --------------------------                   
Guarantors and the Trustee may amend this Indenture or the Securities without
notice to or consent of any Securityholder:

          (1)  to cure any ambiguity, omission, defect or inconsistency;

          (2)  to comply with Article IV in respect of the assumption by a
     Successor Company of an obligation of the Company under this Indenture;

          (3)  to provide for uncertificated Securities in addition to or in
     place of certificated Securities; provided, however, that the
     uncertificated Securities are issued in registered form for purposes of
     Section 163(f) of the Code or in a manner such that the uncertificated
     Securities are described in Section 163(f)(2)(B) of the Code;

          (4)  to add guarantees with respect to the Securities or to secure the
     Securities;

          (5)  to add to the covenants of the Company for the benefit of the
     Holders or to surrender any right or power herein conferred upon the
     Company;

          (6)  to comply with any requirements of the SEC in connection with
     qualifying this Indenture under the TIA;
<PAGE>
 
                                                                              72

          (7)  to make any change that does not adversely affect the rights of
     any Securityholder; or

          (8)  to provide for the issuance of the Exchange Securities, which
     will have terms substantially identical in all material respects to the
     Initial Securities (except that the transfer restrictions contained in the
     Initial Securities will be modified or eliminated, as appropriate), and
     which will be treated, together with any outstanding Initial Securities, as
     a single issue of securities.

          An amendment under this Section may not make any change that adversely
affects the rights under Article X of any holder of Senior Indebtedness or under
Article XII of any holder of Guarantor Senior Indebtedness then outstanding
unless the holders of such Senior Indebtedness (or any group or representative
thereof authorized to give a consent) consent to such change.

          After an amendment under this Section becomes effective, the Company
shall mail to Securityholders a notice briefly describing such amendment.  The
failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section.

          SECTION IX.2.  With Consent of Holders.  The Company, the Guarantors
                         -----------------------                              
and the Trustee may amend this Indenture or the Securities without notice to any
Securityholder but with the written consent of the Holders of at least a
majority in principal amount of the Securities.  However, without the consent of
each Securityholder affected, an amendment may not:

          (1)  reduce the amount of Securities whose Holders must consent to an
     amendment;

          (2)  reduce the rate of or extend the time for payment of interest on
     any Security;

          (3)  reduce the principal of or extend the Stated Maturity of any
     Security;

          (4)  reduce the premium payable upon the redemption or repurchase of
     any Security or change the time at which any Security may or shall be
     redeemed or repurchased in accordance with this Indenture;

          (5)  make any Security payable in money other than that stated in the
     Security;

          (6)  impair the right of any Holder to receive payment of principal of
     and interest on such Holder's Securities on or after the due dates therefor
     or to institute suit for the enforcement of any payment on or with respect
     to such Holder's Securities;

          (7)  make any change to the amendment provisions which require each
     Holder's consent or to the waiver provisions.

                                                                              73

          It shall not be necessary for the consent of the Holders under this
Section to approve the particular form of any proposed amendment, but it shall
be sufficient if such consent approves the substance thereof.

          An amendment under this Section may not make any change that adversely
affects the rights under Article X or Article XII of any holder of Senior
Indebtedness or Guarantor Senior Indebtedness then outstanding unless the
holders of such Senior Indebtedness or Guarantor Senior Indebtedness (or any
group or representative thereof authorized to give a consent) consent to such
change.

          After an amendment under this Section becomes effective, the Company
shall mail to Securityholders a notice briefly describing such amendment.  The
failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section.

          SECTION IX.3.  Compliance with Trust Indenture Act.  Every amendment
                         -----------------------------------                  
to this Indenture or the Securities shall comply with the TIA as then in effect.

          SECTION IX.4.  Revocation and Effect of Consents and Waivers.  A
                         ---------------------------------------------    
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security.  However, any
such Holder or subsequent Holder may revoke the consent or waiver as to such
Holder's Security or portion of the Security if the Trustee receives the notice
of revocation before the date the amendment or waiver becomes effective.  After
an amendment or waiver becomes effective, it shall bind every Securityholder.
An amendment or waiver shall become effective upon receipt by the Trustee of the
requisite number of written consents under Section 9.1 or 9.2 as applicable.
                                           -----------    ---               

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Securityholders entitled to give their consent or
take any other action described above or required or permitted to be taken
pursuant to this Indenture.  If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Securityholders at such
record date (or their duly designated proxies), and only those Persons, shall be
entitled to give such consent or to revoke any consent previously given or to
take any such action, whether or not such Persons continue to be Holders after
such record date.  No such consent shall become valid or effective more than 120
days after such record date.

          SECTION IX.5.  Notation on or Exchange of Securities.  If an amendment
                         -------------------------------------                  
changes the terms of a Security, the Trustee may require the Holder of the
Security to deliver it to the Trustee.  The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder.  Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Security shall issue and the Trustee shall

                                                                              74

authenticate a new Security that reflects the changed terms. Failure to make the
appropriate notation or to issue a new Security shall not affect the validity of
such amendment.

          SECTION IX.6.  Trustee To Sign Amendments.  The Trustee shall sign any
                         --------------------------                             
amendment authorized pursuant to this Article IX if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it.  In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
to receive, and (subject to Sections 7.1 and 7.2) shall be fully protected in
                            --------------------                             
relying upon, an Officers' Certificate and an Opinion of Counsel stating that
such amendment is authorized or permitted by this Indenture.

by the Securities and other obligations relating to the Securities are

this Article X, to the prior payment when due in cash or Cash Equivalents of all
Senior Indebtedness and that the subordination is for the benefit of and

     for, the commencement of any proceeding at the rate specified in the
     applicable Senior Indebtedness, whether or not a claim for such interest
     would be allowed) before Securityholders shall be entitled to receive any
     payment of principal of or interest on or other amounts with respect to the
     Securities; and

          (2)  until the Senior Indebtedness is paid in full in cash or Cash
     Equivalents, any payment or distribution to which Securityholders would be
     entitled but for this Article X shall be made to holders of Senior
     Indebtedness as their respective interests may appear.

been rescinded in writing or (y) such Senior Indebtedness of the Company has
been paid in full in cash or Cash Equivalents; provided, however, that the
Company may pay the Securities without regard to the foregoing if the Company
and the Trustee receive written notice approving such payment from the
Representative of the Senior Indebtedness of the Company with respect to which
either of the events set forth in clause (i) or (ii) of this sentence has
occurred or is continuing. During the continuance of any default (other than a
default described in clause (i) or (ii) of the preceding sentence) with respect
to any Designated Senior Indebtedness pursuant to which the maturity thereof may
be accelerated immediately without further notice (except such notice as may be
required to effect such acceleration) or the expiration of any applicable grace
periods, the Company may not pay the Securities for a period (a "Payment
                                                                 -------
Blockage Period") commencing upon the receipt by the Trustee (with a copy to the
- ---------------             
Company) of written notice (a "Blockage Notice") of such default from the
                               --------------- 
Representative of the holders of such Designated Senior Indebtedness specifying
an election to effect a Payment Blockage Period and ending 179 days thereafter
(or earlier if such Payment Blockage Period is terminated (i) by written notice
to the Trustee and the Company from the Person or Persons who gave such Blockage
Notice, (ii) because the default giving rise to such Blockage Notice is no
longer continuing or (iii) because such Designated Senior Indebtedness has been
repaid in full in cash or Cash Equivalents). Notwithstanding the provisions of
the immediately preceding sentence, unless the holders of such Designated Senior
Indebtedness or the Representative of such holders shall have accelerated the
maturity of such Designated Senior Indebtedness, the Company may resume payments
on the Securities after the end of such Payment Blockage Period. Not more than
one Blockage Notice may be given in any consecutive 360-day period, irrespective
of the number of defaults with respect to Designated Senior Indebtedness during
such period.

          SECTION X.4.  Acceleration of Payment of Securities.  If payment of
                        -------------------------------------                
the Securities is accelerated because of an Event of Default, the Company or the
Trustee shall promptly notify the holders of the Designated Senior Indebtedness
(or their Representatives) of the acceleration; provided, however, that the
Company and the Trustee shall be obligated to notify such a Representative only
if such Representative has delivered or caused to be delivered to the Company
and the Trustee an address for service of such a notice (and the Company and the
Trustee shall only be obligated to deliver the notice to the address so
specified).  If any Designated Senior Indebtedness is outstanding, the Company
shall not pay the Securities until five Business Days after the holders or
Representative of such Designated Senior Indebtedness receives notice of such
acceleration and, thereafter, may pay the Securities only if this Article X
otherwise permits payments at that time.

          SECTION X.5.  When Distribution Must Be Paid Over.  If a payment or
                        -----------------------------------                  
distribution is made to the Trustee or Securityholders that because of this
Article X should not have been made to them, the Trustee or the Securityholders
who receive the payment or distribution shall hold it in trust for holders of
Senior Indebtedness and promptly pay it over to them as their respective
interests may appear.

          SECTION X.6.  Subrogation.  After all Senior Indebtedness is paid in
                        -----------                                           
full in cash or Cash Equivalents and until the Securities are paid in full,
Securityholders shall be subrogated to the rights of holders of Senior
Indebtedness to receive distributions applicable to Senior Indebtedness.  A
payment or distribution made under this Article X to holders of Senior
Indebtedness which otherwise would have been made to Securityholders is not, as
between the Company and Securityholders, a payment by the Company of Senior
Indebtedness.

          SECTION X.7.  Relative Rights.  This Article X defines the relative
                        ---------------                                      
rights of Securityholders and holders of Senior Indebtedness.  Nothing in this
Indenture shall:

          (1)  impair, as between the Company and Securityholders, the
     obligation of the Company, which is absolute and unconditional, to pay
     principal of and interest on the Securities in accordance with their terms;
     or

          (2)  prevent the Trustee or any Securityholder from exercising its
     available remedies upon a Default or Event of Default, subject to the
     rights of holders of Senior Indebtedness to receive payments and
     distributions otherwise payable to Securityholders.

          SECTION X.8.  Subordination May Not Be Impaired by Company.  No right
                        --------------------------------------------           
of any holder of Senior Indebtedness to enforce the subordination of the
Indebtedness evidenced by the Securities shall be impaired by any act or failure
to act by the Company or by the failure of any of them to comply with this
Indenture.

          SECTION X.9.  Rights of Trustee and Paying Agent.  Notwithstanding
                        ----------------------------------                  
Section 10.3, the Trustee or Paying Agent may continue to make payments on the
- ------------                                                                  
Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than one
Business Day prior to the date of such payment, a Trust Officer of the Trustee
receives notice satisfactory to it that payments may not be made under this
Article X.  The Company, the Registrar or co-registrar, the Paying Agent, a
Representative or a holder of Senior Indebtedness may give the notice; provided,
however, that, if an issue of Senior Indebtedness has a Representative, only the
Representative may give the notice.

          The Trustee in its individual or any other capacity may hold Senior
Indebtedness with the same rights it would have if it were not Trustee.  The
Registrar and co-registrar and the Paying Agent may do the same with like
rights.  The Trustee shall be entitled to all the rights set forth in this
Article X with respect to any Senior Indebtedness which may at any time be held
by it, to the same extent as any other holder of Senior Indebtedness; and
nothing in Article VII shall deprive the Trustee of any of its rights as such
holder.  Nothing in this Article X shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 7.7.  Each Paying Agent shall have the same
                             -----------                                        
rights and obligations under this Article X as does the Trustee.

          SECTION X.10. Distribution or Notice to Representative.  Whenever a
                        ----------------------------------------             
payment or distribution is to be made or a notice given to holders of Senior
Indebtedness, the payment or distribution may be made and the notice given to
their Representative (if any).

          SECTION X.11.  Article X Not To Prevent Events of Default or Limit
                         ---------------------------------------------------
Right To Accelerate.  The failure to make a payment in respect of the Securities
- -------------------                                                             
by reason of any provision in this Article X shall not be construed as
preventing the occurrence of a Default or Event of Default.  Nothing in this
Article X shall have any effect on the right of the Securityholders or the
Trustee to accelerate the maturity of the Securities.

          SECTION X.12.  Trust Moneys Not Subordinated.  Notwithstanding
                         -----------------------------                  
anything contained herein to the contrary, payments from money or the proceeds
of U.S. Government Obligations held in trust under Article VIII by the Trustee
for the payment of principal of and interest on the Securities shall not be
subordinated to the prior payment of any Senior Indebtedness or subject to the
restrictions set forth in this Article X, and none of the Securityholders shall
be obligated to pay over any such amount to the Company, any holder of Senior
Indebtedness of the Company, or any other creditor of the Company.

          SECTION X.13.  Trustee Entitled To Rely.  Upon any payment or
                         ------------------------                      
distribution pursuant to this Article X, the Trustee and the Securityholders
shall be entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 10.2
                                                                   ------------
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representatives for the holders of Senior
Indebtedness for the purpose of ascertaining the Persons entitled to participate
in such payment or distribution, the holders of Senior Indebtedness and other
Indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article X.  In the event that the Trustee determines, in good faith,
that evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to
this Article X, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and other facts pertinent to the rights of such
Person under this Article X, and, if such evidence is not furnished, the Trustee
may defer any payment to such Person pending judicial determination as to the
right of such Person to receive such payment.  The provisions of Sections 7.1
                                                                 ------------
and 7.2 shall be applicable to all actions or omissions of actions by the
    ---                                                                  
Trustee pursuant to this Article X.

          SECTION X.14.  Trustee To Effectuate Subordination.  Each
                         -----------------------------------       
Securityholder by accepting a Security authorizes and directs the Trustee on its
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination between the Securityholders and the holders of
Senior Indebtedness as provided in this Article X and appoints the Trustee as
attorney-in-fact for any and all such purposes.

          SECTION X.15.  Trustee Not Fiduciary for Holders of Senior
                         -------------------------------------------
Indebtedness.  The Trustee shall not be deemed to owe any fiduciary duty to the
- ------------                                                                   
holders of Senior Indebtedness and, subject to Section 10.9, shall not be liable
to any such holders if it shall mistakenly pay over or

                                                                              78

distribute to Securityholders or the Company or any other Person, money or
assets to which any holders of Senior Indebtedness shall be entitled by virtue
of this Article X or otherwise.

          SECTION X.16.  Reliance by Holders of Senior Indebtedness on
                         ---------------------------------------------
Subordination Provisions.  Each Securityholder by accepting a Security
- ------------------------                                              
acknowledges and agrees that the foregoing subordination provisions are, and are
intended to be, an inducement and a consideration to each holder of any Senior
Indebtedness, whether such Senior Indebtedness was created or acquired before or
after the issuance of the Securities, to acquire and continue to hold, or to
continue to hold, such Senior Indebtedness and such holder of Senior
Indebtedness shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such
Senior Indebtedness.

                                  ARTICLE XI

                                   Guarantee
                                   ---------

          SECTION XI.1.  Guarantee.  Each Guarantor hereby fully,
                         ---------                               
unconditionally and irrevocably guarantees, as primary obligor and not merely as
surety, jointly and severally with each other Guarantor, to each Holder of the
Securities the full and punctual payment when due, whether at maturity, by
acceleration, by redemption or otherwise, of the principal of, premium, if any,
and interest on the Securities (all the foregoing being hereinafter collectively
called the "Obligations").  Each Guarantor further agrees (to the extent
permitted by law) that the Obligations may be extended or renewed, in whole or
in part, without notice or further assent from it, and that it will remain bound
under this Article XI notwithstanding any extension or renewal of any
Obligation. Notwithstanding anything to the contrary contained herein, AHI and
Holdings may merge with or consolidate into one another, so long as the
surviving Person Guarantees the full and prompt payment of the principal of,
premium, if any, and interest on the Securities on a senior subordinated basis.

          Each Guarantor waives presentation to, demand of payment from and
protest to the Company of any of the Obligations and also waives notice of
protest for nonpayment.  Each Guarantor waives notice of any default under the
Securities or the Obligations.  The obligations of each Guarantor hereunder
shall not be affected by (a) the failure of any Holder to assert any claim or
demand or to enforce any right or remedy against the Company or any other person
under the Indenture, the Securities or any other agreement or otherwise; (b) any
extension or renewal of any thereof; (c) any rescission, waiver, amendment or
modification of any of the terms or provisions of the Indenture, the Securities
or any other agreement; (d) the release of any security held by any Holder or
the Trustee for the Obligations or any of them; (e) the failure of any Holder to
exercise any right or remedy against any other Guarantor; or (f) any change in
the ownership of the Company.

          Each Guarantor further agrees that its Note Guarantee herein
constitutes a Guarantee of payment when due (and not a Guarantee of collection)
and waives any right to require that any resort be had by any Holder to any
security held for payment of the Obligations.
<PAGE>
 
                                                                              79

          The Note Guarantee of each Guarantor is, to the extent and in the
manner set forth in Article XII, subordinated and subject in right of payment to
the prior payment in full of all Guarantor Senior Indebtedness of such Guarantor
and the Note Guarantee is made subject to such provisions of such Guarantees.

          The obligations of each Guarantor hereunder shall not be subject to
any reduction, limitation, impairment or termination for any reason (other than
payment of the Obligations in full), including any claim of waiver, release,
surrender, alteration or compromise, and shall not be subject to any defense of
setoff, counterclaim, recoupment or termination whatsoever or by reason of the
invalidity, illegality or unenforceability of the Obligations or otherwise.
Without limiting the generality of the foregoing, the obligations of each
Guarantor herein shall not be discharged or impaired or otherwise affected by
the failure of any Holder to assert any claim or demand or to enforce any remedy
under the Indenture, the Securities or any other agreement, by any waiver or
modification of any thereof, by any default, failure or delay, willful or
otherwise, in the performance of the Obligations, or by any other act or thing
or omission or delay to do any other act or thing which may or might in any
manner or to any extent vary the risk of any Guarantor or would otherwise
operate as a discharge of such Guarantor as a matter of law or equity.

          Each Guarantor further agrees that its Note Guarantee herein shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of principal of or interest on any of the
Obligations is rescinded or must otherwise be restored by any Holder upon the
bankruptcy or reorganization of the Company or otherwise.

          In furtherance of the foregoing and not in limitation of any other
right which any Holder has at law or in equity against any Guarantor by virtue
hereof, upon the failure of the Company to pay any of the Obligations when and
as the same shall become due, whether at maturity, by acceleration, by
redemption or otherwise, each Guarantor hereby promises to and will, upon
receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in
cash, to the Holders an amount equal to the sum of (i) the unpaid amount of such
Obligations then due and owing and (ii) accrued and unpaid interest on such
Obligations then due and owing (but only to the extent not prohibited by law).

          Each Guarantor further agrees that, as between such Guarantor, on the
one hand, and the Holders, on the other hand, (x) the maturity of the
Obligations guaranteed hereby may be accelerated as provided in the Indenture
for the purposes of the Note Guarantee herein, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the
Obligations guaranteed hereby and (y) in the event of any such declaration of
acceleration of such Obligations, such Obligations (whether or not due and
payable) shall forthwith become due and payable by the Guarantor for the
purposes of this Note Guarantee.

          Each Guarantor also agrees to pay any and all reasonable costs and
expenses (including reasonable attorneys' fees) incurred by the Trustee or the
Holders in enforcing any rights under this Section.

          SECTION XI.2.  Limitation on Liability; Termination, Release and
                         -------------------------------------------------
Discharge.  The obligations of each Guarantor hereunder will be limited to the
- ---------                                                                     
maximum amount as will, after giving effect to all other contingent and fixed
liabilities of such Guarantor (including, without limitation, any Guarantees
under the Senior Credit Agreement) and after giving effect to any collections
from or payments made by or on behalf of any other Guarantor in respect of the
obligations of such other Guarantor under its Note Guarantee or pursuant to its
contribution obligations under the Indenture or as set forth below, result in
the obligations of the Guarantor under this Note Guarantee not constituting a
fraudulent conveyance or fraudulent transfer under federal or state law.

          Each Subsidiary Guarantor may consolidate with or merge into or sell
its assets to the Company or another Wholly-Owned Subsidiary Guarantor without
limitation. Each Subsidiary Guarantor may consolidate with or merge into or sell
all or substantially all its assets to a corporation, partnership, trust,
limited partnership, limited liability company or other similar entity other
than the Company or a Wholly-Owned Subsidiary Guarantor (whether or not
affiliated with the Subsidiary Guarantor), except that if the surviving
corporation of any such merger or consolidation is a Subsidiary of the Company,
such Subsidiary shall not be a Foreign Subsidiary. Upon the sale or disposition
of a Subsidiary Guarantor (by merger, consolidation, the sale of its Capital
Stock or the sale of all or substantially all of its assets) to a Person
(whether or not an Affiliate of the Subsidiary Guarantor) which is not a
Subsidiary of the Company, which sale or disposition is otherwise in compliance
with this Indenture (including Section 3.7), such Subsidiary Guarantor shall be
deemed released from all its obligations under this Indenture and its Subsidiary
Guarantee and such Subsidiary Guarantee shall terminate; provided, however, that
any such termination shall occur only to the extent that all obligations of such
Subsidiary Guarantor under the Senior Credit Agreement and all of its Guarantees
of, and under all of its pledges of assets or other security interests which
secure, any other Indebtedness of the Company shall also terminate upon such
release, sale or transfer.

          SECTION XI.3.  Right of Contribution.  Each Guarantor hereby agrees
                         ----------------------                              
that to the extent that any Guarantor shall have paid more than its
proportionate share of any payment made on the obligations under the Note
Guarantees, such Guarantor shall be entitled to seek and receive contribution
from and against the Company or any other Guarantor who has not paid its
proportionate share of such payment.  Each Guarantor's right of contribution
shall be subject to the terms and conditions of Section 3.6.  The provisions of
this Section 11.3 shall in no respect limit the obligations and liabilities of
each Guarantor to the Trustee and the Holders and each Guarantor shall remain
liable to the Trustee and the Holders for the full amount guaranteed by such
Guarantor hereunder.

          SECTION XI.4.  No Subrogation.  Notwithstanding any payment or
                         --------------                                 
payments made by each Guarantor hereunder, no Guarantor shall be entitled to be
subrogated to any of the rights of the Trustee or any Holder against the Company
or any other Guarantor or any collateral security or guarantee or right of
offset held by the Trustee or any Holder for the payment of the Obligations, nor
shall any Guarantor seek or be entitled to seek any contribution or
reimbursement from the Company or any other Guarantor in respect of payments
made by such Guarantor hereunder, until all amounts owing to the Trustee and the
Holders by the Company on 
<PAGE>
 
                                                                              81

account of the Obligations are paid in full. If any amount shall be paid to any
Guarantor on account of such subrogation rights at any time when all of the
Obligations shall not have been paid in full, such amount shall be held by such
Guarantor in trust for the Trustee and the Holders, segregated from other funds
of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be
turned over to the Trustee in the exact form received by such Guarantor (duly
indorsed by such Guarantor to the Trustee, if required), to be applied against
the Obligations.


                                  ARTICLE XII

                       Subordination of Note Guarantees
                       --------------------------------

          SECTION XII.1.  Agreement To Subordinate.  Each Guarantor agrees, and
                          ------------------------                             
each Securityholder by accepting a Security agrees, that the Indebtedness
evidenced by each Note Guarantee and other obligations relating to the
Securities are subordinated in right of payment, to the extent and in the manner
provided in this Article XII, to the prior payment when due in cash or Cash
Equivalents of all Guarantor Senior Indebtedness and that the subordination is
for the benefit of and enforceable by the holders of Guarantor Senior
Indebtedness.  Each Note Guarantee shall in all respects rank pari passu with
                                                              ---- -----     
all other Guarantor Senior Subordinated Indebtedness of such Guarantor and only
Indebtedness of the Guarantor which is Guarantor Senior Indebtedness will rank
senior to such Note Guarantee in accordance with the provisions set forth
herein.  All provisions of this Article XII shall be subject to Section 12.12.

          SECTION XII.2.  Liquidation, Dissolution, Bankruptcy.  Upon any
                          ------------------------------------           
payment or distribution of the assets or securities of any Guarantor upon a
total or partial liquidation or a total or partial dissolution of a Guarantor or
in a bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to any Guarantor or its respective properties:

          (1)  holders of Guarantor Senior Indebtedness  shall be entitled to
     receive payment in full in cash or Cash Equivalents of the Guarantor Senior
     Indebtedness (including interest accruing after, or which would accrue but
     for, the commencement of any proceeding at the rate specified in the
     applicable Guarantor Senior Indebtedness, whether or not a claim for such
     interest would be allowed) before Securityholders shall be entitled to
     receive any payment of principal of, premium, if any, or interest on or
     other amounts with respect to the Securities; and

          (2)  until the Guarantor Senior Indebtedness is paid in full in cash
     or Cash Equivalents, any payment or distribution to which Securityholders
     would be entitled but for this Article XII shall be made to holders of
     Guarantor Senior Indebtedness as their respective interests may appear.

          SECTION XII.3.  Default on Senior Indebtedness.  No Guarantor shall
                          ------------------------------                     
pay the principal of, premium (if any) or interest on or other amounts with
respect to the Securities or make any deposit pursuant to Section 8.1 or pay the
Securities if (i) any Guarantor Senior Indebtedness or Senior Indebtedness of
the Company is not paid when due in cash or Cash 
<PAGE>
 
                                                                              82

Equivalents or (ii) any other default on Guarantor Senior Indebtedness or Senior
Indebtedness of the Company occurs and the maturity of such Guarantor Senior
Indebtedness or Senior Indebtedness of the Company is accelerated in accordance
with its terms unless, in either case, (x) the default has been cured or waived
and any such acceleration has been rescinded in writing or (y) such Guarantor
Senior Indebtedness or Senior Indebtedness of the Company has been paid in full
in cash or Cash Equivalents; provided, however, that a Guarantor may pay the
Securities without regard to the foregoing if the Company and the Trustee
receive written notice approving such payment from the Representative of the
Guarantor Senior Indebtedness or the Senior Indebtedness of the Company with
respect to which either of the events set forth in clause (i) or (ii) of this
sentence has occurred or is continuing. During the continuance of any default
(other than a default described in clause (i) or (ii) of the preceding sentence)
with respect to any Designated Senior Indebtedness pursuant to which the
maturity thereof may be accelerated immediately without further notice (except
such notice as may be required to effect such acceleration) or the expiration of
any applicable grace periods, the Guarantor may not pay the Securities for a
Payment Blockage Period commencing upon the receipt by the Trustee (with a copy
to the Company) of a Blockage Notice of such default from the Representative of
the holders of such Designated Senior Indebtedness specifying an election to
effect a Payment Blockage Period and ending 179 days thereafter (or earlier if
such Payment Blockage Period is terminated (i) by written notice to the Trustee
and the Company from the Person or Persons who gave such Blockage Notice, (ii)
because the default giving rise to such Blockage Notice is no longer continuing
or (iii) because such Designated Senior Indebtedness has been repaid in full in
cash or Cash Equivalents). Notwithstanding the provisions of the immediately
preceding sentence, unless the holders of such Designated Senior Indebtedness or
the Representative of such holders shall have accelerated the maturity of such
Designated Senior Indebtedness, a Guarantor may resume payments on the
Securities after the end of such Payment Blockage Period. Not more than one
Blockage Notice may be given in any consecutive 360-day period, irrespective of
the number of defaults with respect to Designated Senior Indebtedness during
such period.

          SECTION XII.4.  Acceleration of Payment of Securities.  If payment of
                          -------------------------------------                
the Securities is accelerated because of an Event of Default and if any
Designated Senior Indebtedness is outstanding, no Guarantor shall pay the
Securities until five Business Days after the holders or Representative of the
Designated Senior Indebtedness receives notice of such acceleration as provided
in the Indenture and, thereafter, Guarantors may pay the Securities only if this
Article XII otherwise permits payments at that time.

          SECTION XII.5.  When Distribution Must Be Paid Over.  If a payment or
                          -----------------------------------                  
distribution is made to the Trustee or Securityholders that because of this
Article XII should not have been made to them, the Trustee or the
Securityholders who receive the payment or distribution shall hold it in trust
for holders of Guarantor Senior Indebtedness and promptly pay it over to them as
their respective interests may appear.

          SECTION XII.6.  Subrogation.  After all Guarantor Senior Indebtedness
                          -----------                                          
is paid in full in cash or Cash Equivalents and the Securities are paid in full,
Securityholders shall be subrogated to the rights of holders of Guarantor Senior
Indebtedness to receive distributions 
<PAGE>
 
                                                                              83

applicable to Guarantor Senior Indebtedness. A payment or distribution made
under this Article XII to holders of Guarantor Senior Indebtedness which
otherwise would have been made to Securityholders is not, as between a Guarantor
and Securityholders, a payment by such Guarantor of Guarantor Senior
Indebtedness.

          SECTION XII.7.  Relative Rights.  This Article XII defines the
                          ---------------                               
relative rights of Holders and holders of Guarantor Senior Indebtedness.
Nothing in the Note Guarantee shall:

          (1)  impair, as between a Guarantor and Holders, the obligation of a
     Guarantor which is absolute and unconditional, to pay the Obligations in
     accordance with the terms of the Note Guarantee; or

          (2)  prevent the Trustee or any Securityholder from exercising its
     available remedies upon a Default or Event of Default, subject to the
     rights of holders of Guarantor Senior Indebtedness to receive payments and
     distributions otherwise payable to Securityholders.

          SECTION XII.8.  Subordination May Not Be Impaired by Guarantor.  No
                          ----------------------------------------------     
right of any holder of Guarantor Senior Indebtedness to enforce the
subordination of the Indebtedness evidenced by the Note Guarantee shall be
impaired by any act or failure to act by a Guarantor or by the failure of any of
them to comply with the Note Guarantee or this Indenture.

          SECTION XII.9.  Rights of Trustee and Paying Agent.  Notwithstanding
                          ----------------------------------                  
Section 12.3, the Trustee or Paying Agent may continue to make payments on the
Securities and shall not be charged with knowledge of the existence of facts
that would prohibit the making of any such payments unless, not less than one
Business Day prior to the date of such payment, a Trust Officer of the Trustee
receives notice satisfactory to it that payments may not be made under this
Article XII.  A Guarantor, the Company, the Registrar or co-registrar, the
Paying Agent, a Representative or a holder of Senior Indebtedness of the Company
or Guarantor Senior Indebtedness may give the notice; provided, however, that,
if an issue of Senior Indebtedness of the Company or Guarantor Senior
Indebtedness has a Representative, only the Representative may give the notice.

          The Trustee in its individual or any other capacity may hold Guarantor
Senior Indebtedness with the same rights it would have if it were not Trustee.
The Registrar and co-registrar and the Paying Agent may do the same with like
rights.  The Trustee shall be entitled to all the rights set forth in this
Article XII with respect to any Guarantor Senior Indebtedness which may at any
time be held by it, to the same extent as any other holder of Guarantor Senior
Indebtedness; and nothing in Article VII shall deprive the Trustee of any of its
rights as such holder.  Nothing in this Article XII shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 7.7.  Each Paying Agent
shall have the same rights and obligations under this Article XII as does the
Trustee.

          SECTION XII.10.  Distribution or Notice to Representative.  Whenever a
                           ----------------------------------------             
payment or distribution is to be made or a notice given to holders of Guarantor
Senior 
<PAGE>
 
                                                                              84

Indebtedness, the payment or distribution may be made and the notice given to
their Representative (if any).

          SECTION XII.11.  Article XII Not To Prevent Events of Default or Limit
                           -----------------------------------------------------
Right To Accelerate.  The failure to make a payment in respect of the Securities
- -------------------                                                             
by reason of any provision in this Article XII shall not be construed as
preventing the occurrence of a Default or Event of Default.  Nothing in this
Article XII shall have any effect on the right of the Securityholders or the
Trustee to accelerate the maturity of the Securities.

          SECTION XII.12.  Trust Moneys Not Subordinated.  Notwithstanding
                           -----------------------------                  
anything contained herein to the contrary, payments from money or the proceeds
of U.S. Government Obligations held in trust under Article VIII by the Trustee
for the payment of principal of and interest on the Securities shall not be
subordinated to the prior payment of any Guarantor Senior Indebtedness or
subject to the restrictions set forth in this Article XII, and none of the
Securityholders shall be obligated to pay over any such amount to a Guarantor,
any holder of Guarantor Senior Indebtedness or Senior Indebtedness of the
Company, or any other creditor of a Guarantor or the Company.

          SECTION XII.13.  Trustee Entitled To Rely.  Upon any payment or
                           ------------------------                      
distribution pursuant to this Article XII, the Trustee and the Securityholders
shall be entitled to rely (i) upon any order or decree of a court of competent
jurisdiction in which any proceedings of the nature referred to in Section 12.2
are pending, (ii) upon a certificate of the liquidating trustee or agent or
other Person making such payment or distribution to the Trustee or to the
Securityholders or (iii) upon the Representatives for the holders of Guarantor
Senior Indebtedness or Senior Indebtedness of the Company for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Guarantor Senior Indebtedness or Senior
Indebtedness and other Indebtedness of the Company or a Guarantor, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article XII.  In the event that
the Trustee determines, in good faith, that evidence is required with respect to
the right of any Person as a holder of Guarantor Senior Indebtedness to
participate in any payment or distribution pursuant to this Article XII, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Guarantor Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and other facts pertinent to the rights of such
Person under this Article XII, and, if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.  The provisions of Sections
7.1 and 7.2 shall be applicable to all actions or omissions of actions by the
Trustee pursuant to this Article XII.

          SECTION XII.14.  Trustee To Effectuate Subordination.  Each
                           -----------------------------------       
Securityholder by accepting a Security authorizes and directs the Trustee on its
behalf to take such action as may be necessary or appropriate to acknowledge or
effectuate the subordination between the Securityholders and the holders of
Guarantor Senior Indebtedness and Senior Indebtedness of the Company as provided
in this Article XII and appoints the Trustee as attorney-in-fact for any and all
such purposes.

          SECTION XII.15.  Trustee Not Fiduciary for Holders of Senior

Indebtedness.  The Trustee shall not be deemed to owe any fiduciary duty to the

holders of Guarantor Senior Indebtedness or Senior Indebtedness of the Company
and, subject to Section 12.9, shall not be liable to any such holders if it
shall mistakenly pay over or distribute to Securityholders or the Company or any
other Person, money or assets to which any holders of Guarantor Senior
Indebtedness shall be entitled by virtue of this Article XII or otherwise.

          SECTION XII.16.  Reliance on Subordination Provisions.  Each
                           ------------------------------------       
Securityholder by accepting a Security acknowledges and agrees that the
foregoing subordination provisions are, and are intended to be, an inducement
and a consideration to each holder of any Guarantor Senior Indebtedness, whether
such Guarantor Senior Indebtedness was created or acquired before or after the
issuance of the Securities, to acquire and continue to hold, or to continue to
hold, such Guarantor Senior Indebtedness and such holder of Guarantor Senior
Indebtedness shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such
Guarantor Senior Indebtedness.

                   9 1/4% Senior Subordinated Note due 2008


1.   Interest
     --------

          Advanstar Communications Inc., a New York corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Security at the rate per annum shown above.

          The Company will pay interest semiannually on May 1 and November 1 of
each year commencing November 1, 1998. Interest on the Securities will accrue
from the most recent date to which interest has been paid on the Securities or,
if no interest has been paid, from April 30, 1998. The Company shall pay
interest on overdue principal or premium, if any (plus interest on such interest
to the extent lawful), at the rate borne by the Securities to the extent lawful.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

2.   Method of Payment
     -----------------

          By at least 10:00 a.m. (New York City time) on the date on which any
principal of or interest on any Security is due and payable, the Company shall
irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay
such principal, premium, if any, and/or interest.  The Company will pay interest
(except Defaulted Interest) to the Persons who are registered Holders of
Securities at the close of business on the April 15 or October 15 next preceding
the interest payment date even if Securities are cancelled, repurchased or
redeemed after the record date and on or before the interest payment date.
Holders must surrender Securities to a Paying Agent to collect principal
payments.  The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts.  However, the Company may pay principal and interest by check
payable in such money.  It may mail an interest check to a Holder's registered
address.

3.   Paying Agent and Registrar
     --------------------------

          Initially, The Bank of New York, a banking corporation duly organized
and existing under the laws of the State of New York (the "Trustee"), will act
as Trustee, Paying Agent and Registrar.  The Company may appoint and change any
Paying Agent, Registrar or co-registrar without notice to any Securityholder.
The Company or any of its domestically incorporated Wholly-Owned Subsidiaries
may act as Paying Agent, Registrar or co-registrar.
<PAGE>
 
4.   Indenture
     ---------

          The Company issued the Securities under an Indenture dated as of April
30, 1998 (as it may be amended or supplemented from time to time in accordance
with the terms thereof, the "Indenture"), between the Company and the Trustee.
The terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
                                                                          ------
(S)(S) 77aaa-77bbbb) as in effect on the date of the Indenture (the "Act").
Capitalized terms used herein and not defined herein have the meanings ascribed
thereto in the Indenture.  The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
those terms.

          The Securities are general unsecured senior subordinated obligations
of the Company limited to $150.0 million aggregate principal amount (subject to
Section 2.9 of the Indenture).  The aggregate principal amount of notes which
- -----------                                                                  
may be authenticated and delivered under the Indenture, including the
Securities, is limited to $250.0 million (subject to Section 2.9 of the
                                                     -----------       
Indenture).  This Security is one of the Initial Securities referred to in the
Indenture.  The Securities include the Initial Securities and any Exchange
Securities issued in exchange for the Initial Securities pursuant to the
Indenture and the Registration Rights Agreement.  The Initial Securities and the
Exchange Securities are treated as a single class of securities under the
Indenture.  The Indenture imposes certain limitations on: the Incurrence of
Indebtedness by the Company and its Restricted Subsidiaries, the Incurrence of
Indebtedness by the Company and its Subsidiary Guarantors if subordinate or
junior in any respect to any Senior Indebtedness or Guarantor Senior
Indebtedness, respectively, the payment of dividends and other distributions on
the Capital Stock of the Company and its Restricted Subsidiaries, the purchase
or redemption of Capital Stock of the Company and Capital Stock of such
Restricted Subsidiaries, certain purchases or redemptions of Subordinated
Indebtedness, the Incurrence of Liens by the Company or its Restricted
Subsidiaries, the entering into of Asset Swaps by the Company or its Restricted
Subsidiaries, the sale or transfer of assets and Capital Stock of Restricted
Subsidiaries, the issuance or sale of Capital Stock of Restricted Subsidiaries,
the business activities and investments of the Company and its Restricted
Subsidiaries and, transactions with Affiliates.  In addition, the Indenture
limits the ability of the Company and its Restricted Subsidiaries to restrict
distributions and dividends from Restricted Subsidiaries.

     To guarantee the due and punctual payment of the principal, premium, if
any, and interest on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Subsidiary Guarantors have
unconditionally guaranteed (and future Subsidiary Guarantors, together with the
Subsidiary Guarantors, will unconditionally guarantee), jointly and severally,
such obligations on a senior subordinated basis pursuant to the terms of the
Indenture.

5.   Redemption
     ----------

          Except as set forth below, the Securities will not be redeemable at
the option of the Company prior to May 1, 2003. On and after such date, the
Securities will be redeemable, at the Company's option, in whole or in part, at
any time upon not less than 30 nor more than 60 days prior 
<PAGE>
 
notice mailed by first-class mail to each holder's registered address, at the
following redemption prices (expressed in percentages of principal amount), plus
accrued and unpaid interest to the redemption date (subject to the right of
holders of record on the relevant record date to receive interest due on the
relevant interest payment date):

     If redeemed during the 12-month period commencing on May 1 of the years set
forth below:

2003                                                          104.625      % 
2004                                                          103.083      % 
2005                                                          101.542      % 
2006 and thereafter                                           100.000      %  
</TABLE>

          In addition, at any time and from time to time prior to  May 1, 2001,
the Company may redeem in the aggregate up to 35% of the original principal
amount of the Securities with the proceeds of one or more Equity Offerings
received by, or invested in, the Company so long as there is a Public Market at
the time of such redemption, at a redemption price (expressed as a percentage of
principal amount) of 109.250% plus accrued and unpaid interest, if any, to the
redemption date (subject to the right of holders of record on the relevant
record date to receive interest due on the relevant interest payment date);
provided, however, that at least 65% of the original principal amount of the
Securities must remain outstanding after each such redemption; provided further,
however, that each such redemption occurs within 90 days of the date of closing
of such Equity Offering.

          At any time on or prior to May 1, 2003, the Securities may also be
redeemed as a whole at the option of the Company upon the occurrence of a Change
of Control, upon not less than 30 nor more than 60 days prior notice (but in no
event more than 30 days after the occurrence of such Change of Control) mailed
by first-class mail to each holder's registered address, at a redemption price
equal to 100% of the principal amount thereof plus the Applicable Premium as of,
and accrued and unpaid interest, if any, to, the date of redemption (the
"Redemption Date") (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date).

          "Applicable Premium" means, with respect to a Security at any
Redemption Date, the greater of (i) 1.0% of the principal amount of such
Security and (ii) the excess of (A) the present value at such time of (1) the
redemption price of such Security at May 1, 2003 (such redemption price being
described under "Optional Redemption") plus (2) all required interest payments
due on such Security through May 1, 2003, computed using a discount rate equal
to the Treasury Rate plus 50 basis points, over (B) the principal amount of such
Note.

          "Treasury Rate" means the yield to maturity at the time of computation
of United States Treasury securities with a constant maturity (as compiled 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
Redemption Date (or, if such Statistical Release is no longer published, any
publicly available source of similar market data)) most nearly equal to the
period from the Redemption Date to  May 1, 2003; provided, however, that if the
period from the Redemption Date to May 1, 2003 is not equal to the constant
maturity of a United States Treasury security for which a weekly average yield
is given, the Treasury Rate shall 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 such yields are given, except
that if the period from the Redemption Date to May 1, 2003 is less than one
year, the 
<PAGE>
 
weekly average yield on actually traded United States Treasury securities
adjusted to a constant maturity of one year shall be used.

     In the case of any partial redemption, selection of the Securities for
redemption will be made by the Trustee on a pro rata basis, by lot or by such
other method as the Trustee in its sole discretion shall deem to be fair and
appropriate, although no Securities of $1,000 in original principal amount or
less will be redeemed in part. If any Security is to be redeemed in part only,
the notice of redemption relating to such Security shall state the portion of
the principal amount thereof to be redeemed. A new Security in principal amount
equal to the unredeemed portion thereof will be issued in the name of the holder
thereof upon cancellation of the original Security.

6.   Repurchase Provisions
     ---------------------

          (1) Upon a Change of Control, unless the Company has exercised its
right to redeem the Securities as described under Section 5 hereof, any Holder
of Securities will have the right to cause the Company to repurchase all or any
part of the Securities of such Holder at a purchase price in cash equal to 101%
of the principal amount thereof, plus accrued and unpaid interest, if any, to
the date of repurchase (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date) as provided in, and subject to the terms of, the Indenture.

          (b) If the Company or a Restricted Subsidiary consummates any Asset
Sales permitted by the Indenture, when the aggregate amount of Excess Proceeds
equals or exceeds $5.0 million, the Company shall make an Offer for all
outstanding Securities pro rata up to a maximum principal amount (expressed as a
multiple of $1,000) of Securities equal to such Excess Proceeds, at a purchase
price in cash equal to 100% of the principal amount thereof, plus accrued and
unpaid interest thereon, if any, to the date of purchase in accordance with the
procedures set forth in Section 3.7 of the Indenture.
                        -----------                  

7.   Subordination
     -------------

          The Securities are subordinated to Senior Indebtedness and the Note
Guarantees are subordinated to Guarantor Senior Indebtedness, each as defined in
the Indenture.  To the extent provided in the Indenture, Senior Indebtedness
must be paid before the Securities may be paid.  The Company agrees, and each
Securityholder by accepting a Security agrees, to the subordination provisions
contained in the Indenture and authorizes the Trustee to give them effect and
appoints the Trustee as attorney-in-fact for such purpose.  The Securities will
in all respects rank pari passu with all other Senior Subordinated Indebtedness.
<PAGE>
 
8.   Denominations; Transfer; Exchange
     ---------------------------------

          The Securities are in registered form without coupons in denominations
of principal amount of $1,000 and whole multiples of $1,000.  A Holder may
transfer or exchange Securities in accordance with the Indenture.  The Registrar
may require a Holder, among other things, to furnish appropriate endorsements or
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture.  The Registrar need not register the transfer of or exchange (i)
any Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) for a period
beginning 15 days before the mailing of a notice of Securities to be redeemed
and ending on the date of such mailing or (ii) any Securities for a period
beginning 15 days before an interest payment date and ending on such interest
payment date.

9.   Persons Deemed Owners
     ---------------------

          The registered holder of this Security may be treated as the owner of
it for all purposes.

10.  Unclaimed Money
     ---------------

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its request unless an abandoned property law designates another
Person.  After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

11.  Defeasance
     ----------

          Subject to certain conditions set forth in the Indenture, the Company
at any time may terminate some or all of its obligations under the Securities
and the Indenture if the Company deposits with the Trustee money or U.S.
Government Obligations for the payment of principal and interest on the
Securities to redemption or maturity, as the case may be.

12.  Amendment, Waiver
     -----------------

          Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the then outstanding
Securities and (ii) any default (other than with respect to nonpayment) or
noncompliance with any provision may be waived with the written consent of the
Holders of a majority in principal amount of the then outstanding Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of
any Securityholder, the Company and the Trustee may amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article IV of the Indenture, or to provide for uncertificated
Securities in addition to or in place of certificated Securities, or to add
guarantees with respect to the Securities or to secure the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company, or
to comply with any request of the SEC in connection with qualifying the
Indenture under the Act, or to make any change that does not adversely affect
the rights of any Securityholder, or to provide for the issuance of Exchange
Securities.
<PAGE>
 
13.  Defaults and Remedies
     ---------------------

          Under the Indenture, Events of Default include (i) default for 30 days
in payment of interest when due on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon required repurchase, upon required
repurchase or upon redemption pursuant to paragraphs 5 and 6 of the Securities,
upon declaration or otherwise; (iii) the failure by the Company to comply with
its obligations under Article IV of the Indenture, (iv) failure by the Company
                      ----------                                              
to comply for 30 days after notice with any of its obligations under the
covenants described under Section 3.9 of the Indenture or under other covenants
                          -----------                                           
specified in the Indenture (in each case, other than a failure to purchase
Securities, which shall constitute an Event of Default under clause (ii) above),
(v) the failure by the Company to comply for 60 days after notice with its other
agreements contained in the Indenture, (vi) Indebtedness of the Company or any
Restricted Subsidiary if not paid within any applicable grace period after final
maturity or is accelerated by the holders thereof because of a default and the
total amount of such Indebtedness unpaid or accelerated exceeds $10 million (the
"cross acceleration provision"), (vii) certain events of bankruptcy, insolvency
or reorganization of the Company or a Significant Subsidiary (the "bankruptcy
provisions"), (viii) any judgment or decree for the payment of money in excess
of $5.0 million is rendered against the Company or a Significant Subsidiary and
such judgment or decree shall remain undischarged or unstayed for a period of 60
days after such judgment becomes final and non-appealable (the "judgment default
provision") or (ix) any Note Guarantee ceases to be in full force and effect
(except as contemplated by the terms of the Indenture) or any Guarantor denies
or disaffirms its obligations under the Indenture or its Note Guarantee.
However, a default under clauses (iv) and (v) will not constitute an Event of
Default until the Trustee or the holders of more than 25% in principal amount of
the outstanding Securities notify the Company of the default and the Company
does not cure such default within the time specified in clauses (iv) and (v)
hereof after receipt of such notice.

          If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Securities may declare all
the Securities to be due and payable immediately.  Certain events of bankruptcy
or insolvency are Events of Default which will result in the Securities being
due and payable immediately upon the occurrence of such Events of Default.

          Securityholders may not enforce the Indenture or the Securities except
as provided in the Indenture.  The Trustee may refuse to enforce the Indenture
or the Securities unless it receives reasonable indemnity or security.  Subject
to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power.  The
Trustee may withhold from Securityholders notice of any continuing Default or
Event of Default (except a Default or Event of Default in payment of principal
or interest) if it determines that withholding notice is in their interest.

14.  Trustee Dealings with the Company
     ---------------------------------

          Subject to certain limitations set forth in the Indenture, the Trustee
under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its affiliates with the same rights it would have if it were
not Trustee.
<PAGE>
 
15.  No Recourse Against Others
     --------------------------

          An incorporator, director, officer, employee, stockholder or
controlling person, as such, of the Company shall not have any liability for any
obligations of the Company under the Securities or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation.  By accepting a Security, each Securityholder waives and releases all
such liability.  The waiver and release are part of the consideration for the
issue of the Securities.

the Securities referred
to in the Indenture.

                   9 1/4% Senior Subordinated Note due 2008

1.   Interest
     --------

          Advanstar Communications Inc., a New York corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal amount of this Security at the rate per annum shown above.

          The Company will pay interest semiannually on May 1 and November 1 of
each year commencing November 1, 1998.  Interest on the Securities will accrue
from the most recent date to which interest has been paid on the Securities or,
if no interest has been paid, from April 30, 1998.  The Company shall pay
interest on overdue principal or premium, if any (plus interest on such interest
to the extent lawful), at the rate borne by the Securities to the extent lawful.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

2.   Method of Payment
     -----------------

          By at least 10:00 a.m. (New York City time) on the date on which any
principal of or interest on any Security is due and payable, the Company shall
irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay
such principal, premium, if any, and/or interest.  The Company will pay interest
(except Defaulted Interest) to the Persons who are registered Holders of the
Securities at the close of business on the April 15 or October 15 next preceding
the interest payment date even if Securities are cancelled, repurchased or
redeemed after the record date and on or before the interest payment date.
Holders must surrender Securities to a Paying Agent to collect principal
payments.  The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts.  However, the Company may pay principal and interest by check
payable in such money.  It may mail an interest check to a Holder's registered
address.

3.   Paying Agent and Registrar
     --------------------------

          Initially, The Bank of New York, a banking corporation duly organized
and existing under the laws of the State of New York (the "Trustee"), will act
as Trustee, Paying Agent and Registrar.  The Company may appoint and change any
Paying Agent, Registrar or co-registrar without notice to any Securityholder.
The Company or any of its domestically incorporated Wholly-Owned Subsidiaries
may act as Paying Agent, Registrar or co-registrar.
<PAGE>
 
4.   Indenture
     ---------

          The Company issued the Securities under an Indenture dated as of April
30, 1998 (as it may be amended or supplemented from time to time in accordance
with the terms thereof, the "Indenture"), between the Company and the Trustee.
The terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
                                                                          ------
(S)(S) 77aaa-77bbbb) as in effect on the date of the Indenture (the "Act").
Capitalized terms used herein and not defined herein have the meanings ascribed
thereto in the Indenture.  The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
those terms.

          The Securities are general unsecured senior subordinated obligations
of the Company limited to $150.0 million aggregate principal amount (subject to
Section 2.9 of the Indenture).  The aggregate principal amount of notes which
- -----------                                                                  
may be authenticated and delivered under the Indenture, including the
Securities, is limited to $250.0 million (subject to Section 2.9 of the
                                                     -----------       
Indenture).  This Security is one of the Exchange Securities referred to in the
Indenture.  The Securities include the Initial Securities and any Exchange
Securities issued in exchange for the Initial Securities pursuant to the
Indenture and the Registration Rights Agreement.  The Initial Securities and the
Exchange Securities are treated as a single class of securities under the
Indenture.  The Indenture imposes certain limitations on:  the Incurrence of
Indebtedness by the Company and its Restricted Subsidiaries, the Incurrence of
Indebtedness by the Company and its Subsidiary Guarantors if subordinate or
junior in any respect to any Senior Indebtedness or Guarantor Senior
Indebtedness, respectively, the payment of dividends and other distributions on
the Capital Stock of the Company and its Restricted Subsidiaries, the purchase
or redemption of Capital Stock of the Company and Capital Stock of such
Restricted Subsidiaries, certain purchases or redemptions of Subordinated
Indebtedness, the Incurrence of Liens by the Company or its Restricted
Subsidiaries, the entering into of Asset Swaps by the Company or its Restricted
Subsidiaries, the sale or transfer of assets and Capital Stock of Restricted
Subsidiaries, the issuance or sale of Capital Stock of Restricted Subsidiaries,
the business activities and investments of the Company and its Restricted
Subsidiaries, and transactions with Affiliates.  In addition, the Indenture
limits the ability of the Company and its Subsidiaries to restrict distributions
and dividends from Restricted Subsidiaries.

     To guarantee the due and punctual payment of the principal, premium, if
any, and interest on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Subsidiary Guarantors have
unconditionally guaranteed (and future Subsidiary Guarantors, together with the
Subsidiary Guarantors, will unconditionally guarantee), jointly and severally,
such obligations on a senior subordinated basis pursuant to the terms of the
Indenture.

5.   Optional Redemption
     -------------------

     Except as set forth below, the Securities will not be redeemable at the
option of the Company prior to May 1, 2003. On and after such date, the
Securities will be redeemable, at the Company's option, in whole or in part, at
any time upon not less than 30 nor more than 60 days prior notice mailed by
first-class mail to each holder's registered address, at the following
redemption prices (expressed in 
<PAGE>
 
percentages of principal amount), plus accrued and unpaid interest to the
redemption date (subject to the right of holders of record on the relevant
record date to receive interest due on the relevant interest payment date):
<PAGE>
 
     If redeemed during the 12-month period commencing on May 1 of the years set
forth below:

2003                                                           104.625     % 
2004                                                           103.083     % 
2005                                                           101.542     % 
2006 and thereafter                                            100.000     %  
</TABLE>

     In addition, at any time and from time to time prior to  May 1, 2001, the
Company may redeem in the aggregate up to 35% of the original principal amount
of the Securities with the proceeds of one or more Equity Offerings received by,
or invested in, the Company so long as there is a Public Market at the time of
such redemption, at a redemption price (expressed as a percentage of principal
amount) of 109.250% plus accrued and unpaid interest, if any, to the redemption
date (subject to the right of holders of record on the relevant record date to
receive interest due on the relevant interest payment date); provided, however,
that at least 65% of the original principal amount of the Securities must remain
outstanding after each such redemption; provided further, that each such
redemption occurs within 90 days of the date of closing of such Equity Offering.

     At any time on or prior to May 1, 2003, the Securities may also be redeemed
as a whole at the option of the Company upon the occurrence of a Change of
Control, upon not less than 30 nor more than 60 days prior notice (but in no
event more than 30 days after the occurrence of such Change of Control) mailed
by first-class mail to each holder's registered address, at a redemption price
equal to 100% of the principal amount thereof plus the Applicable Premium as of,
and accrued and unpaid interest, if any, to, the date of redemption (the
"Redemption Date") (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date).

     "Applicable Premium" means, with respect to a Security at any Redemption
Date, the greater of (i) 1.0% of the principal amount of such Security and (ii)
the excess of (A) the present value at such time of (1) the redemption price of
such Security at  May 1, 2003 (such redemption price being described under
"Optional Redemption") plus (2) all required interest payments due on such
Security through May 1, 2003, computed using a discount rate equal to the
Treasury Rate plus 50 basis points, over (B) the principal amount of such Note.

     "Treasury Rate" means the yield to maturity at the time of computation of
United States Treasury securities with a constant maturity (as compiled 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
Redemption Date (or, if such Statistical Release is no longer published, any
publicly available source of similar market data)) most nearly equal to the
period from the Redemption Date to May 1, 2003; provided, however, that if the
period from the Redemption Date to  May 1, 2003 is not equal to the constant
maturity of a United States Treasury security for which a weekly average yield
is given, the Treasury Rate shall 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 such yields are given, except
that if the period from the Redemption Date to May 1, 2003 is less than one
year, the weekly average yield on actually traded United States Treasury
securities adjusted to a constant maturity of one year shall be used.
<PAGE>
 
     In the case of any partial redemption, selection of the Securities for
redemption will be made by the Trustee on a pro rata basis, by lot or by such
other method as the Trustee in its sole discretion shall deem to be fair and
appropriate, although no Securities of $1,000 in original principal amount or
less will be redeemed in part. If any Security is to be redeemed in part only,
the notice of redemption relating to such Security shall state the portion of
the principal amount thereof to be redeemed. A new Security in principal amount
equal to the unredeemed portion thereof will be issued in the name of the holder
thereof upon cancellation of the original Security.

6.   Repurchase Provisions
     ---------------------

          .1   Upon a Change of Control, unless the Company has exercised its
right to redeem the Securities as described under Section 5 hereof, any Holder
of Securities will have the right to cause the Company to repurchase all or any
part of the Securities of such Holder at a purchase price in cash equal to 101%
of the principal amount thereof, plus accrued and unpaid interest, if any, to
the date of repurchase (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date) as provided in, and subject to the terms of, the Indenture.

          (b) If the Company or a Restricted Subsidiary consummates any Asset
Sales permitted by the Indenture, when the aggregate amount of Excess Proceeds
equals or exceeds $5.0 million, the Company shall make an Offer for all
outstanding Securities pro rata up to a maximum principal amount (expressed as a
multiple of $1,000) of Securities equal to such Excess Proceeds, at a purchase
price in cash equal to 100% of the principal amount thereof, plus accrued and
unpaid interest thereon, if any, to the date of purchase in accordance with the
procedures set forth in Section 3.7 of the Indenture.
                        -----------                  

7.   Subordination
     -------------

          The Securities are subordinated to Senior Indebtedness and the Note
Guarantees are subordinated to Guarantor Senior Indebtedness, each as defined in
the Indenture.  To the extent provided in the Indenture, Senior Indebtedness
must be paid before the Securities may be paid.  The Company agrees, and each
Securityholder by accepting a Security agrees, to the subordination provisions
contained in the Indenture and authorizes the Trustee to give them effect and
appoints the Trustee as attorney-in-fact for such purpose.  The Securities will
in all respects rank pari passu with all other Senior Subordinated Indebtedness.
<PAGE>
 
8.   Denominations; Transfer; Exchange
     ---------------------------------

          The Securities are in registered form without coupons in denominations
of principal amount of $1,000 and whole multiples of $1,000.  A Holder may
transfer or exchange Securities in accordance with the Indenture.  The Registrar
may require a Holder, among other things, to furnish appropriate endorsements or
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture.  The Registrar need not register the transfer of or exchange (i)
any Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or for a
period beginning 15 days before the mailing of a notice of Securities to be
redeemed and ending on the date of such mailing or (ii) any Securities for a
period beginning 15 days before an interest payment date and ending on such
interest payment date.

9.   Persons Deemed Owners
     ---------------------

          The registered holder of this Security may be treated as the owner of
it for all purposes.

10.  Unclaimed Money
     ---------------

          If money for the payment of principal or interest remains unclaimed
for two years, the Trustee or Paying Agent shall pay the money back to the
Company at its request unless an abandoned property law designates another
person.  After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

11.  Defeasance
     ----------

          Subject to certain conditions set forth in the Indenture, the Company
at any time may terminate some or all of its obligations under the Securities
and the Indenture if the Company deposits with the Trustee money or U.S.
Government Obligations for the payment of principal and interest on the
Securities to redemption or maturity, as the case may be.

12.  Amendment, Waiver
     -----------------

          Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount of the then outstanding
Securities and (ii) any default (other than with respect to nonpayment) or
noncompliance with any provision may be waived with the written consent of the
Holders of a majority in principal amount of the then outstanding Securities.
Subject to certain exceptions set forth in the Indenture, without the consent of
any Securityholder, the Company and the Trustee may amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article IV of the Indenture, or to provide for uncertificated
Securities in addition to or in place of certificated Securities, or to add
guarantees with respect to the Securities or to secure the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company or

qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Securityholder, or to provide for the

13.  Defaults and Remedies
     ---------------------

          Under the Indenture, Events of Default include (i) default for 30 days
in payment of interest when due on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon required repurchase, upon required
repurchase or upon redemption pursuant to paragraphs 5 and 6 of the Securities,
upon declaration or otherwise; (iii) the failure by the Company to comply with
its obligations under Article IV of the Indenture (iv) failure by the Company to
                      ----------                                                
comply for 30 days after notice with any of its obligations under the covenants
described under Section 3.9 of the Indenture or under other covenants specified
                -----------                                                    
in the Indenture (in each case, other than a failure to purchase Securities,
which shall constitute an Event of Default under clause (ii) above), (v) the
failure by the Company to comply for 60 days after notice with its other
agreements contained in the Indenture, (vi) Indebtedness of the Company or any
Restricted Subsidiary if not paid within any applicable grace period after final
maturity or is accelerated by the holders thereof because of a default and the
total amount of such Indebtedness unpaid or accelerated exceeds $5.0 million
(the "cross acceleration provision"), (vii) certain events of bankruptcy,
insolvency or reorganization of the Company or a Significant Subsidiary (the
"bankruptcy provisions"), (viii) any judgment or decree for the payment of money
in excess of $5.0 million is rendered against the Company or a Significant
Subsidiary and such judgment or decree shall remain undischarged or unstayed for
a period of 60 days after such judgment becomes final and non-appealable (the
"judgment default provision") or (ix) any Note Guarantee ceases to be in full
force and effect (except as contemplated by the terms of the Indenture) or any
Guarantor denies or disaffirms its obligations under the Indenture or its Note
Guarantee.  However, a default under clauses (iv) and (v) will not constitute an
Event of Default until the Trustee or the holders of more than 25% in principal
amount of the outstanding Securities notify the Company of the default and the
Company does not cure such default within the time specified in clauses (iv) and
(v) hereof after receipt of such notice.

          If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Securities may declare all
the Securities to be due and payable immediately.  Certain events of bankruptcy
or insolvency are Events of Default which will result in the Securities being
due and payable immediately upon the occurrence of such Events of Default.

          Securityholders may not enforce the Indenture or the Securities except
as provided in the Indenture.  The Trustee may refuse to enforce the Indenture
or the Securities unless it receives reasonable indemnity or security.  Subject
to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power.  The
Trustee may withhold from Securityholders notice of any continuing Default or
Event of Default (except a Default or Event of Default in payment of principal
or interest) if it determines that withholding notice is in their interest.

14.  Trustee Dealings with the Company
     ---------------------------------

          Subject to certain limitations set forth in the Indenture, the Trustee
under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its affiliates with the same rights it would have if it were
not Trustee.
<PAGE>
 
15.  No Recourse Against Others
     --------------------------

          An incorporator, director, officer, employee, stockholder or
controlling person, as such, of the Company shall not have any liability for any
obligations of the Company under the Securities or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation.  By accepting a Security, each Securityholder waives and releases all
such liability.  The waiver and release are part of the consideration for the
issue of the Securities.

16.  Authentication
     --------------

          This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent acting on its behalf) manually signs the
certificate of authentication on the other side of this Security.

17.  Abbreviations
     -------------

          Customary abbreviations may be used in the name of a Securityholder or
an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entirety), JT TEN (=joint tenants with rights of survivorship and not as tenants
in common), CUST (=custodian) and U/G/M/A (=Uniform Gift to Minors Act).

18.  CUSIP Numbers
     -------------

          Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders.  No representation is
made as to the accuracy of such numbers either as printed on the Securities or
as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

19.  Governing Law
     -------------

          This Security shall be governed by, and construed in accordance with,
the laws of the State of New York but without giving effect to applicable
principles of conflicts of law to the extent that the application of the laws of
another jurisdiction would be required thereby.

1.  Interest
    --------

  Advanstar Communications Inc., a New York corporation (such corporation, and
its successors and assigns under the Indenture hereinafter referred to, being
herein called the "Company"), promises to pay interest on the principal amount
of this Security at the rate per annum shown above.

  The Company will pay interest semiannually on May 1 and November 1 of each
year commencing November 1, 1998.  Interest on the Securities will accrue from
the most recent date to which interest has been paid on the Securities or, if no
interest has been paid, from April 30, 1998.  The Company shall pay interest on
overdue principal or premium, if any (plus interest on such interest to the
extent lawful), at the rate borne by the Securities to the extent lawful.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

2.  Method of Payment
    -----------------

  By at least 10:00 a.m. (New York City time) on the date on which any principal
of or interest on any Security is due and payable, the Company shall irrevocably

redeemed after the record date and on or before the interest payment date.

payments.  The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts.  However, the Company may pay principal and interest by check
payable in such money.  It may mail an interest check to a Holder's registered
address.

Company and its Restricted Subsidiaries and, transactions with Affiliates.  In
addition, the Indenture limits the ability of the Company and its Restricted
Subsidiaries to restrict distributions and dividends from Restricted
Subsidiaries.

  To guarantee the due and punctual payment of the principal, premium, if any,
and interest on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Subsidiary Guarantors have
unconditionally guaranteed (and future Subsidiary Guarantors, together with the
Subsidiary Guarantors, will unconditionally guarantee), jointly and severally,
such obligations on a senior subordinated basis pursuant to the terms of the
Indenture.

5.  Redemption
    ----------

  Except as set forth below, the Securities will not be redeemable at the option
of the Company prior to  May 1, 2003. On and after such date, the Securities
will be redeemable, at the Company's option, in whole or in part, at any time
upon not less than 30 nor more than 60 days prior notice mailed by first-class
mail to each holder's registered address, at the following redemption prices
(expressed in percentages of principal amount), plus accrued and unpaid interest
to the redemption date (subject to the right of holders of record on the
relevant record date to receive interest due on the relevant interest payment
date):

  If redeemed during the 12-month period commencing on May 1 of the years set
forth below:
<TABLE>

2003                                                      104.625%
2004                                                      103.083%
2005                                                      101.542%
2006 and thereafter                                       100.000%
</TABLE>

  In addition, at any time and from time to time prior to  May 1, 2001, the
Company may redeem in the aggregate up to 35% of the original principal amount
of the Securities with the proceeds of one or more Equity Offerings received by,
or invested in, the Company so long as there is a Public Market at the time of
such redemption, at a redemption price (expressed as a percentage of principal
amount) of 109.250% plus accrued and unpaid interest, if any, to the redemption
date (subject to the right of holders of record on the relevant record date to
receive interest due on the relevant interest payment date); provided, however,
that at least 65% of the original principal amount of the Securities must remain
outstanding after each such redemption; provided further, however, that each
such redemption occurs within 90 days of the date of closing of such Equity
Offering.

  At any time on or prior to May 1, 2003, the Securities may also be redeemed as
a whole at the option of the Company upon the occurrence of a Change of Control,
upon not less than 30 nor more than 60 days prior notice (but in no event more
than 30 days after the occurrence of such Change of Control) mailed by first-
class mail to each holder's registered address, at a redemption price equal to
100% of the principal amount thereof plus the Applicable Premium as of, and
accrued and unpaid interest, if any, to, the date of redemption (the "Redemption
Date") (subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date).

  "Applicable Premium" means, with respect to a Security at any Redemption Date,
the greater of (i) 1.0% of the principal amount of such Security and (ii) the
excess of (A) the
<PAGE>
 
                                                                               4

present value at such time of (1) the redemption price of such Security at May
1, 2003 (such redemption price being described under "Optional Redemption") plus
(2) all required interest payments due on such Security through May 1, 2003,
computed using a discount rate equal to the Treasury Rate plus 50 basis points,
over (B) the principal amount of such Note.

  "Treasury Rate" means the yield to maturity at the time of computation of
United States Treasury securities with a constant maturity (as compiled 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
Redemption Date (or, if such Statistical Release is no longer published, any
publicly available source of similar market data)) most nearly equal to the
period from the Redemption Date to  May 1, 2003; provided, however, that if the
period from the Redemption Date to May 1, 2003 is not equal to the constant
maturity of a United States Treasury security for which a weekly average yield
is given, the Treasury Rate shall 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 such yields are given, except
that if the period from the Redemption Date to May 1, 2003 is less than one
year, the weekly average yield on actually traded United States Treasury
securities adjusted to a constant maturity of one year shall be used.

  In the case of any partial redemption, selection of the Securities for
redemption will be made by the Trustee on a pro rata basis, by lot or by such
other method as the Trustee in its sole discretion shall deem to be fair and
appropriate, although no Securities of $1,000 in original principal amount or
less will be redeemed in part. If any Security is to be redeemed in part only,
the notice of redemption relating to such Security shall state the portion of
the principal amount thereof to be redeemed. A new Security in principal amount
equal to the unredeemed portion thereof will be issued in the name of the holder
thereof upon cancellation of the original Security.

6.  Repurchase Provisions
    ---------------------

  a.  Upon a Change of Control, unless the Company has exercised its right to
redeem the Securities as described under Section 5 hereof, any Holder of
Securities will have the right to cause the Company to repurchase all or any
part of the Securities of such Holder at a purchase price in cash equal to 101%
of the principal amount thereof, plus accrued and unpaid interest, if any, to
the date of repurchase (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date) as provided in, and subject to the terms of, the Indenture.

   (b) If the Company or a Restricted Subsidiary consummates any Asset Sales
permitted by the Indenture, when the aggregate amount of Excess Proceeds equals
or exceeds $5.0 million, the Company shall make an Offer for all outstanding
Securities pro rata up to a maximum principal amount (expressed as a multiple of
$1,000) of Securities equal to such Excess Proceeds, at a purchase price in cash
equal to 100% of the principal amount thereof, plus accrued and unpaid interest
thereon, if any, to the date of purchase in accordance with the procedures set
forth in Section 3.7 of the Indenture.
         -----------

                                                                               5
7.  Subordination
    -------------

  The Securities are subordinated to Senior Indebtedness and the Note Guarantees
are subordinated to Guarantor Senior Indebtedness, each as defined in the
Indenture.  To the extent provided in the Indenture, Senior Indebtedness must be
paid before the Securities may be paid.  The Company agrees, and each
Securityholder by accepting a Security agrees, to the subordination provisions
contained in the Indenture and authorizes the Trustee to give them effect and
appoints the Trustee as attorney-in-fact for such purpose.  The Securities will
in all respects rank pari passu with all other Senior Subordinated Indebtedness.

8.  Denominations; Transfer; Exchange
    ---------------------------------

  The Securities are in registered form without coupons in denominations of
principal amount of $1,000 and whole multiples of $1,000.  A Holder may transfer
or exchange Securities in accordance with the Indenture.  The Registrar may
require a Holder, among other things, to furnish appropriate endorsements or
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture.  The Registrar need not register the transfer of or exchange (i)
any Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) for a period
beginning 15 days before the mailing of a notice of Securities to be redeemed
and ending on the date of such mailing or (ii) any Securities for a period
beginning 15 days before an interest payment date and ending on such interest
payment date.

9.  Persons Deemed Owners
    ---------------------

  The registered holder of this Security may be treated as the owner of it for
all purposes.

10.  Unclaimed Money
     ---------------

  If money for the payment of principal or interest remains unclaimed for two
years, the Trustee or Paying Agent shall pay the money back to the Company at
its request unless an abandoned property law designates another Person.  After
any such payment, Holders entitled to the money must look only to the Company
and not to the Trustee for payment.

11.  Defeasance
     ----------

  Subject to certain conditions set forth in the Indenture, the Company at any
time may terminate some or all of its obligations under the Securities and the
Indenture if the Company deposits with the Trustee money or U.S. Government
Obligations for the payment of principal and interest on the Securities to
redemption or maturity, as the case may be.
<PAGE>
 
                                                                               6
12.  Amendment, Waiver
     -----------------

  Subject to certain exceptions set forth in the Indenture, (i) the Indenture or
the Securities may be amended with the written consent of the Holders of at
least a majority in principal amount of the then outstanding Securities and (ii)
any default (other than with respect to nonpayment) or noncompliance with any
provision may be waived with the written consent of the Holders of a majority in
principal amount of the then outstanding Securities.  Subject to certain
exceptions set forth in the Indenture, without the consent of any
Securityholder, the Company and the Trustee may amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article IV of the Indenture, or to provide for uncertificated
Securities in addition to or in place of certificated Securities, or to add
guarantees with respect to the Securities or to secure the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company, or
to comply with any request of the SEC in connection with qualifying the
Indenture under the Act, or to make any change that does not adversely affect
the rights of any Securityholder, or to provide for the issuance of Exchange
Securities.

13.  Defaults and Remedies
     ---------------------

  Under the Indenture, Events of Default include (i) default for 30 days in
payment of interest when due on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon required repurchase, upon required
repurchase or upon redemption pursuant to paragraphs 5 and 6 of the Securities,
upon declaration or otherwise; (iii) the failure by the Company to comply with
its obligations under Article IV of the Indenture, (iv) failure by the Company
                      ----------                                              
to comply for 30 days after notice with any of its obligations under the
covenants described under Section 3.9  of the Indenture or under other covenants
                          -----------                                           
specified in the Indenture (in each case, other than a failure to purchase
Securities, which shall constitute an Event of Default under clause (ii) above),
(v) the failure by the Company to comply for 60 days after notice with its other
agreements contained in the Indenture, (vi) Indebtedness of the Company or any
Restricted Subsidiary if not paid within any applicable grace period after final
maturity or is accelerated by the holders thereof because of a default and the
total amount of such Indebtedness unpaid or accelerated exceeds $10 million (the
"cross acceleration provision"), (vii) certain events of bankruptcy, insolvency
or reorganization of the Company or a Significant Subsidiary (the "bankruptcy
provisions"), (viii) any judgment or decree for the payment of money in excess
of $5.0 million is rendered against the Company or a Significant Subsidiary and
such judgment or decree shall remain undischarged or unstayed for a period of 60
days after such judgment becomes final and non-appealable (the "judgment default
provision") or (ix) any Note Guarantee ceases to be in full force and effect
(except as contemplated by the terms of the Indenture) or any Guarantor denies
or disaffirms its obligations under the Indenture or its Note Guarantee.
However, a default under clauses (iv) and (v) will not constitute an Event of
Default until the Trustee or the holders of more than 25% in principal amount of
the outstanding Securities notify the Company of the default and the Company
does not cure such default within the time specified in clauses (iv) and (v)
hereof after receipt of such notice.
<PAGE>
 
                                                                               7

  If an Event of Default occurs and is continuing, the Trustee or the Holders of
at least 25% in principal amount of the Securities may declare all the
Securities to be due and payable immediately.  Certain events of bankruptcy or
insolvency are Events of Default which will result in the Securities being due
and payable immediately upon the occurrence of such Events of Default.

  Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture.  The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security.  Subject to
certain limitations, Holders of a majority in principal amount of the Securities
may direct the Trustee in its exercise of any trust or power.  The Trustee may
withhold from Securityholders notice of any continuing Default or Event of
Default (except a Default or Event of Default in payment of principal or
interest) if it determines that withholding notice is in their interest.

14.  Trustee Dealings with the Company
     ---------------------------------

  Subject to certain limitations set forth in the Indenture, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its affiliates with the same rights it would have if it were not Trustee.

15.  No Recourse Against Others
     --------------------------

  An incorporator, director, officer, employee, stockholder or controlling
person, as such, of the Company shall not have any liability for any obligations
of the Company under the Securities or the Indenture or for any claim based on,
in respect of or by reason of such obligations or their creation.  By accepting
a Security, each Securityholder waives and releases all such liability.  The
waiver and release are part of the consideration for the issue of the
Securities.

16.  Authentication
     --------------

  This Security shall not be valid until an authorized signatory of the Trustee
(or an authenticating agent acting on its behalf) manually signs the certificate
of authentication on the other side of this Security.

17.  Abbreviations
     -------------

  Customary abbreviations may be used in the name of a Securityholder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entirety), JT TEN (=joint tenants with rights of survivorship and not as tenants
in common), CUST (=custodian) and U/G/M/A (=Uniform Gift to Minors Act).

18.  CUSIP Numbers
     -------------

  Pursuant to a recommendation promulgated by the Committee on Uniform Security
Identification Procedures the Company has caused CUSIP numbers to be printed on
the Securities and has directed the Trustee to use CUSIP numbers in notices of
redemption as a convenience to Securityholders.  No representation is made as to
the accuracy of such numbers either as printed on the Securities or as contained
in any notice of redemption and reliance may be placed only on the other
identification numbers placed thereon.

19.  Governing Law
     -------------

  This Security shall be governed by, and construed in accordance with, the laws
of the State of New York but without giving effect to applicable principles of
conflicts of law to the extent that the application of the laws of another
jurisdiction would be required thereby.

                   9 1/4% Senior Subordinated Note due 2008


1.  Interest
    --------

  Advanstar Communications Inc., a New York corporation (such corporation, and
its successors and assigns under the Indenture hereinafter referred to, being
herein called the "Company"), promises to pay interest on the principal amount
of this Security at the rate per annum shown above.

  The Company will pay interest semiannually on May 1 and November 1 of each
year commencing November 1, 1998.  Interest on the Securities will accrue from
the most recent date to which interest has been paid on the Securities or, if no
interest has been paid, from April 30, 1998.  The Company shall pay interest on
overdue principal or premium, if any (plus interest on such interest to the
extent lawful), at the rate borne by the Securities to the extent lawful.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

2.  Method of Payment
    -----------------

  By at least 10:00 a.m. (New York City time) on the date on which any principal
of or interest on any Security is due and payable, the Company shall irrevocably
deposit with the Trustee or the Paying Agent money sufficient to pay such
principal, premium, if any, and/or interest.  The Company will pay interest
(except Defaulted Interest) to the Persons who are registered Holders of
Securities at the close of business on the April 15 or October 15 next preceding
the interest payment date even if Securities are cancelled, repurchased or
redeemed after the record date and on or before the interest payment date.
Holders must surrender Securities to a Paying Agent to collect principal
payments.  The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts.  However, the Company may pay principal and interest by check
payable in such money.  It may mail an interest check to a Holder's registered
address.

3.  Paying Agent and Registrar
    --------------------------

  Initially, The Bank of New York, a banking corporation duly organized and
existing under the laws of the State of New York (the "Trustee"), will act as
Trustee, Paying Agent and Registrar.  The Company may appoint and change any
Paying Agent, Registrar or co-registrar without notice to any Securityholder.
The Company or any of its domestically incorporated Wholly-Owned Subsidiaries
may act as Paying Agent, Registrar or co-registrar.

4.  Indenture
    ---------

  The Company issued the Securities under an Indenture dated as of April 30,
1998 (as it may be amended or supplemented from time to time in accordance with
the terms thereof, the "Indenture"), between the Company and the Trustee.  The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
                                                                          ------
(S)(S) 77aaa-77bbbb) as in effect on the date of the Indenture (the "Act").
Capitalized terms used herein and not defined herein have the meanings ascribed
thereto in the Indenture.  The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
those terms.

  The Securities are general unsecured senior subordinated obligations of the
Company limited to $150.0 million aggregate principal amount (subject to Section
                                                                         -------

authenticated and delivered under the Indenture, including the Securities, is
limited to $250.0 million (subject to Section 2.9 of the Indenture).  This
                                      -----------                         
Security is one of the Initial Securities referred to in the Indenture.  The
Securities include the Initial Securities and any Exchange Securities issued in
exchange for the Initial Securities pursuant to the Indenture and the
Registration Rights Agreement.  The Initial Securities and the Exchange
Securities are treated as a single class of securities under the Indenture.  The
Indenture imposes certain limitations on: the Incurrence of Indebtedness by the
Company and its Restricted Subsidiaries, the Incurrence of Indebtedness by the
Company and its Subsidiary Guarantors if subordinate or junior in any respect to
any Senior Indebtedness or Guarantor Senior Indebtedness, respectively, the
payment of dividends and other distributions on the Capital Stock of the Company
and its Restricted Subsidiaries, the purchase or redemption of Capital Stock of
the Company and Capital Stock of such Restricted Subsidiaries, certain purchases
or redemptions of Subordinated Indebtedness, the Incurrence of Liens by the
Company or its Restricted Subsidiaries, the entering into of Asset Swaps by the
Company or its Restricted Subsidiaries, the sale or transfer of assets and
Capital Stock of Restricted Subsidiaries, the issuance or sale of Capital Stock
of Restricted Subsidiaries, the business activities and investments of the
Company and its Restricted Subsidiaries and, transactions with Affiliates.  In
addition, the Indenture limits the ability of the Company and its Restricted
Subsidiaries to restrict distributions and dividends from Restricted
Subsidiaries.

  To guarantee the due and punctual payment of the principal, premium, if any,
and interest on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Subsidiary Guarantors have
unconditionally guaranteed (and future Subsidiary Guarantors, together with the
Subsidiary Guarantors, will unconditionally guarantee), jointly and severally,
such obligations on a senior subordinated basis pursuant to the terms of the
Indenture.

5.  Redemption
    ----------

  Except as set forth below, the Securities will not be redeemable at the option
of the Company prior to  May 1, 2003. On and after such date, the Securities
will be redeemable, at the Company's option, in whole or in part, at any time
upon not less than 30 nor more than 60 days prior notice mailed by first-class
mail to each holder's registered address, at the following redemption prices
(expressed in percentages of principal amount), plus accrued and unpaid interest
to the redemption date (subject to the right of holders of record on the
relevant record date to receive interest due on the relevant interest payment
date):

  If redeemed during the 12-month period commencing on May 1 of the years set
forth below:

  In addition, at any time and from time to time prior to  May 1, 2001, the
Company may redeem in the aggregate up to 35% of the original principal amount
of the Securities with the proceeds of one or more Equity Offerings received by,
or invested in, the Company so long as there is a Public Market at the time of
such redemption, at a redemption price (expressed as a percentage of principal
amount) of 109.250% plus accrued and unpaid interest, if any, to the redemption
date (subject to the right of holders of record on the relevant record date to
receive interest due on the relevant interest payment date); provided, however,
that at least 65% of the original principal amount of the Securities must remain
outstanding after each such redemption; provided further, however, that each
such redemption occurs within 90 days of the date of closing of such Equity
Offering.

  At any time on or prior to May 1, 2003, the Securities may also be redeemed as
a whole at the option of the Company upon the occurrence of a Change of Control,
upon not less than 30 nor more than 60 days prior notice (but in no event more
than 30 days after the occurrence of such Change of Control) mailed by first-
class mail to each holder's registered address, at a redemption price equal to
100% of the principal amount thereof plus the Applicable Premium as of, and
accrued and unpaid interest, if any, to, the date of redemption (the "Redemption
Date") (subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date).

  "Applicable Premium" means, with respect to a Security at any Redemption Date,
the greater of (i) 1.0% of the principal amount of such Security and (ii) the
excess of (A) the 
<PAGE>
 
                                                                               6

present value at such time of (1) the redemption price of such Security at May
1, 2003 (such redemption price being described under "Optional Redemption") plus
(2) all required interest payments due on such Security through May 1, 2003,
computed using a discount rate equal to the Treasury Rate plus 50 basis points,
over (B) the principal amount of such Note.

  "Treasury Rate" means the yield to maturity at the time of computation of
United States Treasury securities with a constant maturity (as compiled 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
Redemption Date (or, if such Statistical Release is no longer published, any
publicly available source of similar market data)) most nearly equal to the
period from the Redemption Date to  May 1, 2003; provided, however, that if the
period from the Redemption Date to May 1, 2003 is not equal to the constant
maturity of a United States Treasury security for which a weekly average yield
is given, the Treasury Rate shall 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 such yields are given, except
that if the period from the Redemption Date to May 1, 2003 is less than one
year, the weekly average yield on actually traded United States Treasury
securities adjusted to a constant maturity of one year shall be used.

  In the case of any partial redemption, selection of the Securities for
redemption will be made by the Trustee on a pro rata basis, by lot or by such
other method as the Trustee in its sole discretion shall deem to be fair and
appropriate, although no Securities of $1,000 in original principal amount or
less will be redeemed in part. If any Security is to be redeemed in part only,
the notice of redemption relating to such Security shall state the portion of
the principal amount thereof to be redeemed. A new Security in principal amount
equal to the unredeemed portion thereof will be issued in the name of the holder
thereof upon cancellation of the original Security.

6.  Repurchase Provisions
    ---------------------

  a.  Upon a Change of Control, unless the Company has exercised its right to
redeem the Securities as described under Section 5 hereof, any Holder of
Securities will have the right to cause the Company to repurchase all or any
part of the Securities of such Holder at a purchase price in cash equal to 101%
of the principal amount thereof, plus accrued and unpaid interest, if any, to
the date of repurchase (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date) as provided in, and subject to the terms of, the Indenture.
<PAGE>
 
                                                                               7


(b)  If the Company or a Restricted Subsidiary consummates any Asset Sales
permitted by the Indenture, when the aggregate amount of Excess Proceeds
equals or exceeds $5.0 million, the Company shall make an Offer for all
outstanding Securities pro rata up to a maximum principal amount (expressed
as a multiple of $1,000) of Securities equal to such Excess Proceeds, at a
purchase price in cash equal to 100% of the principal amount thereof, plus
accrued and unpaid interest thereon, if any, to the date of purchase in
accordance with the procedures set forth in Section 3.7 of the Indenture.
                                            -----------                  

7.  Subordination
    -------------

  The Securities are subordinated to Senior Indebtedness and the Note Guarantees
are subordinated to Guarantor Senior Indebtedness, each as defined in the
Indenture.  To the extent provided in the Indenture, Senior Indebtedness must be
paid before the Securities may be paid.  The Company agrees, and each
Securityholder by accepting a Security agrees, to the subordination provisions
contained in the Indenture and authorizes the Trustee to give them effect and
appoints the Trustee as attorney-in-fact for such purpose.  The Securities will
in all respects rank pari passu with all other Senior Subordinated Indebtedness.

8.  Denominations; Transfer; Exchange
    ---------------------------------

  The Securities are in registered form without coupons in denominations of
principal amount of $1,000 and whole multiples of $1,000.  A Holder may transfer
or exchange Securities in accordance with the Indenture.  The Registrar may
require a Holder, among other things, to furnish appropriate endorsements or
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture.  The Registrar need not register the transfer of or exchange (i)
any Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) for a period
beginning 15 days before the mailing of a notice of Securities to be redeemed
and ending on the date of such mailing or (ii) any Securities for a period
beginning 15 days before an interest payment date and ending on such interest
payment date.

9.  Persons Deemed Owners
    ---------------------

  The registered holder of this Security may be treated as the owner of it for
all purposes.

10.  Unclaimed Money
     ---------------

  If money for the payment of principal or interest remains unclaimed for two
years, the Trustee or Paying Agent shall pay the money back to the Company at
its request unless an abandoned property law designates another Person.  After
any such payment, Holders entitled to the money must look only to the Company
and not to the Trustee for payment.

11.  Defeasance
     ----------

  Subject to certain conditions set forth in the Indenture, the Company at any
time may terminate some or all of its obligations under the Securities and the
Indenture if the Company deposits with the Trustee money or U.S. Government
Obligations for the payment of principal and interest on the Securities to
redemption or maturity, as the case may be.

12.  Amendment, Waiver
     -----------------

  Subject to certain exceptions set forth in the Indenture, (i) the Indenture or
the Securities may be amended with the written consent of the Holders of at
least a majority in principal amount of the then outstanding Securities and (ii)
any default (other than with respect to nonpayment) or noncompliance with any
provision may be waived with the written consent of the Holders of a majority in
principal amount of the then outstanding Securities.  Subject to certain
exceptions set forth in the Indenture, without the consent of any
Securityholder, the Company and the Trustee may amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article IV of the Indenture, or to provide for uncertificated
Securities in addition to or in place of certificated Securities, or to add
guarantees with respect to the Securities or to secure the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company, or
to comply with any request of the SEC in connection with qualifying the
Indenture under the Act, or to make any change that does not adversely affect
the rights of any Securityholder, or to provide for the issuance of Exchange
Securities.

13.  Defaults and Remedies

payment of interest when due on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon required repurchase, upon required

                      ----------                                              
to comply for 30 days after notice with any of its obligations under the
covenants described under Section 3.9  of the Indenture or under other covenants
                          -----------                                           
specified in the Indenture (in each case, other than a failure to purchase
Securities, which shall constitute an Event of Default under clause (ii) above),
(v) the failure by the Company to comply for 60 days after notice with its other
agreements contained in the Indenture, (vi) Indebtedness of the Company or any
Restricted Subsidiary if not paid within any applicable grace period after final
maturity or is accelerated by the holders thereof because of a default and the
total amount of such Indebtedness unpaid or accelerated exceeds $10 million (the
"cross acceleration provision"), (vii) certain events of bankruptcy, insolvency
or reorganization of the Company or a Significant Subsidiary (the "bankruptcy
provisions"), (viii) any judgment or decree for the payment of money in excess
of $5.0 million is rendered against the Company or a Significant Subsidiary and
such judgment or decree shall remain undischarged or unstayed for a period of 60
days after such judgment becomes final and non-appealable (the "judgment default
provision") or (ix) any Note Guarantee ceases to be in full force and effect
(except as contemplated by the terms of the Indenture) or any Guarantor denies
or disaffirms its obligations under the Indenture or its Note Guarantee.
However, a default under clauses (iv) and (v) will not constitute an Event of
Default until the Trustee or the holders of more than 25% in principal amount of
the outstanding Securities notify the Company of the default and the Company
does not cure such default within the time specified in clauses (iv) and (v)
hereof after receipt of such notice.

  If an Event of Default occurs and is continuing, the Trustee or the Holders of
at least 25% in principal amount of the Securities may declare all the
Securities to be due and payable immediately.  Certain events of bankruptcy or
insolvency are Events of Default which will result in the Securities being due
and payable immediately upon the occurrence of such Events of Default.

  Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture.  The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security.  Subject to
certain limitations, Holders of a majority in principal amount of the Securities
may direct the Trustee in its exercise of any trust or power.  The Trustee may
withhold from Securityholders notice of any continuing Default or Event of
Default (except a Default or Event of Default in payment of principal or
interest) if it determines that withholding notice is in their interest.

14.  Trustee Dealings with the Company
     ---------------------------------

  Subject to certain limitations set forth in the Indenture, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its affiliates with the same rights it would have if it were not Trustee.

15.  No Recourse Against Others
     --------------------------

  An incorporator, director, officer, employee, stockholder or controlling
person, as such, of the Company shall not have any liability for any obligations
of the Company under the Securities or the Indenture or for any claim based on,
in respect of or by reason of such obligations or their creation.  By accepting
a Security, each Securityholder waives and releases all such liability.  The
waiver and release are part of the consideration for the issue of the
Securities.

16.  Authentication
     --------------

  This Security shall not be valid until an authorized signatory of the Trustee
(or an authenticating agent acting on its behalf) manually signs the certificate
of authentication on the other side of this Security.

17.  Abbreviations
     -------------

  Customary abbreviations may be used in the name of a Securityholder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entirety), JT TEN (=joint tenants with rights of survivorship and not as tenants
in common), CUST (=custodian) and U/G/M/A (=Uniform Gift to Minors Act).

18.  CUSIP Numbers
     -------------

  Pursuant to a recommendation promulgated by the Committee on Uniform Security
Identification Procedures the Company has caused CUSIP numbers to be printed on
the Securities and has directed the Trustee to use CUSIP numbers in notices of
redemption as a convenience to Securityholders.  No representation is made as to
the accuracy of such numbers either as printed on the Securities or as contained
in any notice of redemption and reliance may be placed only on the other
identification numbers placed thereon.

19.  Governing Law
     -------------

  This Security shall be governed by, and construed in accordance with, the laws
of the State of New York but without giving effect to applicable principles of
conflicts of law to the extent that the application of the laws of another
jurisdiction would be required thereby.

1.  Interest
    --------

  Advanstar Communications Inc., a New York corporation (such corporation, and
its successors and assigns under the Indenture hereinafter referred to, being
herein called the "Company"), promises to pay interest on the principal amount
of this Security at the rate per annum shown above.

  The Company will pay interest semiannually on May 1 and November 1 of each
year commencing November 1, 1998.  Interest on the Securities will accrue from
the most recent date to which interest has been paid on the Securities or, if no
interest has been paid, from April 30, 1998.  The Company shall pay interest on
overdue principal or premium, if any (plus interest on such interest to the
extent lawful), at the rate borne by the Securities to the extent lawful.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

2.  Method of Payment
    -----------------

  By at least 10:00 a.m. (New York City time) on the date on which any principal
of or interest on any Security is due and payable, the Company shall irrevocably
deposit with the Trustee or the Paying Agent money sufficient to pay such
principal, premium, if any, and/or interest.  The Company will pay interest
(except Defaulted Interest) to the Persons who are registered Holders of
Securities at the close of business on the April 15 or October 15 next preceding
the interest payment date even if Securities are cancelled, repurchased or
redeemed after the record date and on or before the interest payment date.
Holders must surrender Securities to a Paying Agent to collect principal
payments.  The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts.  However, the Company may pay principal and interest by check
payable in such money.  It may mail an interest check to a Holder's registered
address.

3.  Paying Agent and Registrar
    --------------------------

  Initially, The Bank of New York, a banking corporation duly organized and
existing under the laws of the State of New York (the "Trustee"), will act as
Trustee, Paying Agent and Registrar.  The Company may appoint and change any
Paying Agent, Registrar or co-registrar without notice to any Securityholder.
The Company or any of its domestically incorporated Wholly-Owned Subsidiaries
may act as Paying Agent, Registrar or co-registrar.

4.  Indenture
    ---------

  The Company issued the Securities under an Indenture dated as of April 30,
1998 (as it may be amended or supplemented from time to time in accordance with
the terms thereof, the "Indenture"), between the Company and the Trustee.  The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
                                                                          ------
(S)(S) 77aaa-77bbbb) as in effect on the date of the Indenture (the "Act").
Capitalized terms used herein and not defined herein have the meanings ascribed
thereto in the Indenture.  The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
those terms.

  The Securities are general unsecured senior subordinated obligations of the
Company limited to $150.0 million aggregate principal amount (subject to Section
                                                                         -------

Security is one of the Initial Securities referred to in the Indenture.  The
Securities include the Initial Securities and any Exchange Securities issued in
exchange for the Initial Securities pursuant to the Indenture and the
Registration Rights Agreement.  The Initial Securities and the Exchange
Securities are treated as a single class of securities under the Indenture.  The
Indenture imposes certain limitations on: the Incurrence of Indebtedness by the
Company and its Restricted Subsidiaries, the Incurrence of Indebtedness by the
Company and its Subsidiary Guarantors if subordinate or junior in any respect to
any Senior Indebtedness or Guarantor Senior Indebtedness, respectively, the

Company and its Restricted Subsidiaries and, transactions with Affiliates.  In

Subsidiaries to restrict distributions and dividends from Restricted
Subsidiaries.

  To guarantee the due and punctual payment of the principal, premium, if any,
and interest on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Subsidiary Guarantors have
unconditionally guaranteed (and future Subsidiary Guarantors, together with the
Subsidiary Guarantors, will unconditionally guarantee), jointly and severally,
such obligations on a senior subordinated basis pursuant to the terms of the
Indenture.

  In addition, at any time and from time to time prior to  May 1, 2001, the
Company may redeem in the aggregate up to 35% of the original principal amount
of the Securities with the proceeds of one or more Equity Offerings received by,
or invested in, the Company so long as there is a Public Market at the time of
such redemption, at a redemption price (expressed as a percentage of principal
amount) of 109.250% plus accrued and unpaid interest, if any, to the redemption
date (subject to the right of holders of record on the relevant record date to
receive interest due on the relevant interest payment date); provided, however,
that at least 65% of the original principal amount of the Securities must remain
outstanding after each such redemption; provided further, however, that each
such redemption occurs within 90 days of the date of closing of such Equity
Offering.

  At any time on or prior to May 1, 2003, the Securities may also be redeemed as
a whole at the option of the Company upon the occurrence of a Change of Control,
upon not less than 30 nor more than 60 days prior notice (but in no event more
than 30 days after the occurrence of such Change of Control) mailed by first-
class mail to each holder's registered address, at a redemption price equal to
100% of the principal amount thereof plus the Applicable Premium as of, and
accrued and unpaid interest, if any, to, the date of redemption (the "Redemption
Date") (subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment date).

  "Applicable Premium" means, with respect to a Security at any Redemption Date,
the greater of (i) 1.0% of the principal amount of such Security and (ii) the
excess of (A) the 
<PAGE>
 
                                                                               5

present value at such time of (1) the redemption price of such Security at May
1, 2003 (such redemption price being described under "Optional Redemption") plus
(2) all required interest payments due on such Security through May 1, 2003,
computed using a discount rate equal to the Treasury Rate plus 50 basis points,
over (B) the principal amount of such Note.

  "Treasury Rate" means the yield to maturity at the time of computation of
United States Treasury securities with a constant maturity (as compiled 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
Redemption Date (or, if such Statistical Release is no longer published, any
publicly available source of similar market data)) most nearly equal to the
period from the Redemption Date to May 1, 2003; provided, however, that if the
period from the Redemption Date to May 1, 2003 is not equal to the constant
maturity of a United States Treasury security for which a weekly average yield
is given, the Treasury Rate shall 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 such yields are given, except
that if the period from the Redemption Date to May 1, 2003 is less than one
year, the weekly average yield on actually traded United States Treasury
securities adjusted to a constant maturity of one year shall be used.

  In the case of any partial redemption, selection of the Securities for
redemption will be made by the Trustee on a pro rata basis, by lot or by such
other method as the Trustee in its sole discretion shall deem to be fair and
appropriate, although no Securities of $1,000 in original principal amount or
less will be redeemed in part. If any Security is to be redeemed in part only,
the notice of redemption relating to such Security shall state the portion of
the principal amount thereof to be redeemed. A new Security in principal amount
equal to the unredeemed portion thereof will be issued in the name of the holder
thereof upon cancellation of the original Security.

6.  Repurchase Provisions
    ---------------------

  a.  Upon a Change of Control, unless the Company has exercised its right to
redeem the Securities as described under Section 5 hereof, any Holder of
Securities will have the right to cause the Company to repurchase all or any
part of the Securities of such Holder at a purchase price in cash equal to 101%
of the principal amount thereof, plus accrued and unpaid interest, if any, to
the date of repurchase (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date) as provided in, and subject to the terms of, the Indenture.


(b)  If the Company or a Restricted Subsidiary consummates any Asset Sales
     permitted by the Indenture, when the aggregate amount of Excess Proceeds
     equals or exceeds $5.0 million, the Company shall make an Offer for all
     outstanding Securities pro rata up to a maximum principal amount (expressed
     as a multiple of $1,000) of Securities equal to such Excess Proceeds, at a
     purchase price in cash equal to 100% of the principal amount thereof, plus
     accrued and unpaid interest thereon, if any, to the date of purchase in
     accordance with the procedures set forth in Section 3.7 of the Indenture.
                                                 -----------                  
<PAGE>
 
                                                                               6

7.  Subordination
    -------------

  The Securities are subordinated to Senior Indebtedness and the Note Guarantees
are subordinated to Guarantor Senior Indebtedness, each as defined in the
Indenture.  To the extent provided in the Indenture, Senior Indebtedness must be
paid before the Securities may be paid.  The Company agrees, and each
Securityholder by accepting a Security agrees, to the subordination provisions
contained in the Indenture and authorizes the Trustee to give them effect and
appoints the Trustee as attorney-in-fact for such purpose.  The Securities will
in all respects rank pari passu with all other Senior Subordinated Indebtedness.

8.  Denominations; Transfer; Exchange
    ---------------------------------

  The Securities are in registered form without coupons in denominations of
principal amount of $1,000 and whole multiples of $1,000.  A Holder may transfer
or exchange Securities in accordance with the Indenture.  The Registrar may
require a Holder, among other things, to furnish appropriate endorsements or
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture.  The Registrar need not register the transfer of or exchange (i)
any Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) for a period
beginning 15 days before the mailing of a notice of Securities to be redeemed
and ending on the date of such mailing or (ii) any Securities for a period
beginning 15 days before an interest payment date and ending on such interest
payment date.

9.  Persons Deemed Owners
    ---------------------

  The registered holder of this Security may be treated as the owner of it for
all purposes.

10.  Unclaimed Money
     ---------------

  If money for the payment of principal or interest remains unclaimed for two
years, the Trustee or Paying Agent shall pay the money back to the Company at
its request unless an abandoned property law designates another Person.  After
any such payment, Holders entitled to the money must look only to the Company
and not to the Trustee for payment.

11.  Defeasance
     ----------

  Subject to certain conditions set forth in the Indenture, the Company at any
time may terminate some or all of its obligations under the Securities and the
Indenture if the Company deposits with the Trustee money or U.S. Government
Obligations for the payment of principal and interest on the Securities to
redemption or maturity, as the case may be.

                                                                               7

12.  Amendment, Waiver
     -----------------

  Subject to certain exceptions set forth in the Indenture, (i) the Indenture or
the Securities may be amended with the written consent of the Holders of at
least a majority in principal amount of the then outstanding Securities and (ii)
any default (other than with respect to nonpayment) or noncompliance with any
provision may be waived with the written consent of the Holders of a majority in
principal amount of the then outstanding Securities.  Subject to certain
exceptions set forth in the Indenture, without the consent of any
Securityholder, the Company and the Trustee may amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article IV of the Indenture, or to provide for uncertificated
Securities in addition to or in place of certificated Securities, or to add
guarantees with respect to the Securities or to secure the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company, or
to comply with any request of the SEC in connection with qualifying the
Indenture under the Act, or to make any change that does not adversely affect
the rights of any Securityholder, or to provide for the issuance of Exchange
Securities.

13.  Defaults and Remedies
     ---------------------

  Under the Indenture, Events of Default include (i) default for 30 days in
payment of interest when due on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon required repurchase, upon required
repurchase or upon redemption pursuant to paragraphs 5 and 6 of the Securities,
upon declaration or otherwise; (iii) the failure by the Company to comply with
its obligations under Article IV of the Indenture, (iv) failure by the Company
                      ----------                                              
to comply for 30 days after notice with any of its obligations under the
covenants described under Section 3.9  of the Indenture or under other covenants
                          -----------                                           
specified in the Indenture (in each case, other than a failure to purchase
Securities, which shall constitute an Event of Default under clause (ii) above),
(v) the failure by the Company to comply for 60 days after notice with its other
agreements contained in the Indenture, (vi) Indebtedness of the Company or any
Restricted Subsidiary if not paid within any applicable grace period after final
maturity or is accelerated by the holders thereof because of a default and the
total amount of such Indebtedness unpaid or accelerated exceeds $10 million (the
"cross acceleration provision"), (vii) certain events of bankruptcy, insolvency
or reorganization of the Company or a Significant Subsidiary (the "bankruptcy
provisions"), (viii) any judgment or decree for the payment of money in excess
of $5.0 million is rendered against the Company or a Significant Subsidiary and
such judgment or decree shall remain undischarged or unstayed for a period of 60
days after such judgment becomes final and non-appealable (the "judgment default
provision") or (ix) any Note Guarantee ceases to be in full force and effect
(except as contemplated by the terms of the Indenture) or any Guarantor denies
or disaffirms its obligations under the Indenture or its Note Guarantee.
However, a default under clauses (iv) and (v) will not constitute an Event of
Default until the Trustee or the holders of more than 25% in principal amount of
the outstanding Securities notify the Company of the default and the Company
does not cure such default within the time specified in clauses (iv) and (v)
hereof after receipt of such notice.
<PAGE>
 
                                                                               8


  If an Event of Default occurs and is continuing, the Trustee or the Holders of
at least 25% in principal amount of the Securities may declare all the
Securities to be due and payable immediately.  Certain events of bankruptcy or
insolvency are Events of Default which will result in the Securities being due
and payable immediately upon the occurrence of such Events of Default.

  Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture.  The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security.  Subject to
certain limitations, Holders of a majority in principal amount of the Securities
may direct the Trustee in its exercise of any trust or power.  The Trustee may
withhold from Securityholders notice of any continuing Default or Event of
Default (except a Default or Event of Default in payment of principal or
interest) if it determines that withholding notice is in their interest.

14.  Trustee Dealings with the Company
     ---------------------------------

  Subject to certain limitations set forth in the Indenture, the Trustee under
the Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its affiliates with the same rights it would have if it were not Trustee.

15.  No Recourse Against Others
     --------------------------

  An incorporator, director, officer, employee, stockholder or controlling
person, as such, of the Company shall not have any liability for any obligations
of the Company under the Securities or the Indenture or for any claim based on,
in respect of or by reason of such obligations or their creation.  By accepting
a Security, each Securityholder waives and releases all such liability.  The
waiver and release are part of the consideration for the issue of the
Securities.

16.  Authentication
     --------------

  This Security shall not be valid until an authorized signatory of the Trustee
(or an authenticating agent acting on its behalf) manually signs the certificate
of authentication on the other side of this Security.

17.  Abbreviations
     -------------

  Customary abbreviations may be used in the name of a Securityholder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entirety), JT TEN (=joint tenants with rights of survivorship and not as tenants
in common), CUST (=custodian) and U/G/M/A (=Uniform Gift to Minors Act).

18.  CUSIP Numbers
     -------------

  Pursuant to a recommendation promulgated by the Committee on Uniform Security
Identification Procedures the Company has caused CUSIP numbers to be printed on
the Securities and has directed the Trustee to use CUSIP numbers in notices of
redemption as a convenience to Securityholders.  No representation is made as to
the accuracy of such numbers either as printed on the Securities or as contained
in any notice of redemption and reliance may be placed only on the other
identification numbers placed thereon.

19.  Governing Law
     -------------

  This Security shall be governed by, and construed in accordance with, the laws
of the State of New York but without giving effect to applicable principles of
conflicts of law to the extent that the application of the laws of another
jurisdiction would be required thereby.

                   9 1/4% Senior Subordinated Note due 2008

1.   Interest
     --------

     Advanstar Communications Inc., a New York corporation (such corporation,
and its successors and assigns under the Indenture hereinafter referred to,
being herein called the "Company"), promises to pay interest on the principal
amount of this Security at the rate per annum shown above.

     The Company will pay interest semiannually on May 1 and November 1 of each
year commencing November 1, 1998.  Interest on the Securities will accrue from
the most recent date to which interest has been paid on the Securities or, if no
interest has been paid, from April 30, 1998.  The Company shall pay interest on
overdue principal or premium, if any (plus interest on such interest to the
extent lawful), at the rate borne by the Securities to the extent lawful.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

2.   Method of Payment
     -----------------

     By at least 10:00 a.m. (New York City time) on the date on which any
principal of or interest on any Security is due and payable, the Company shall
irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay
such principal, premium, if any, and/or interest. The Company will pay interest
(except Defaulted Interest) to the Persons who are registered Holders of the
Securities at the close of business on the April 15 or October 15 next preceding
the interest payment date even if Securities are cancelled, repurchased or
redeemed after the record date and on or before the interest payment date.
Holders must surrender Securities to a Paying Agent to collect principal
payments. The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts. However, the Company may pay principal and interest by check
payable in such money. It may mail an interest check to a Holder's registered
address.

3.   Paying Agent and Registrar
     --------------------------

     Initially, The Bank of New York, a banking corporation duly organized and
existing under the laws of the State of New York (the "Trustee"), will act as
Trustee, Paying Agent and Registrar.  The Company may appoint and change any
Paying Agent, Registrar or co-registrar without notice to any Securityholder.
The Company or any of its domestically incorporated Wholly-Owned Subsidiaries
may act as Paying Agent, Registrar or co-registrar.

4.  Indenture
    ---------

    The Company issued the Securities under an Indenture dated as of April 30,
1998 (as it may be amended or supplemented from time to time in accordance with
the terms thereof, the "Indenture"), between the Company and the Trustee.  The
terms of the Securities include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
                                                                          ------
(S)(S) 77aaa-77bbbb) as in effect on the date of the Indenture (the "Act").
Capitalized terms used herein and not defined herein have the meanings ascribed
thereto in the Indenture.  The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
those terms.

    The Securities are general unsecured senior subordinated obligations of the
Company limited to $150.0 million aggregate principal amount (subject to Section
                                                                         -------
2.9 of the Indenture).  The aggregate principal amount of notes which may be
- ---                                                                         
authenticated and delivered under the Indenture, including the Securities, is
limited to $250.0 million (subject to Section 2.9 of the Indenture).  This
                                      -----------                         
Security is one of the Exchange Securities referred to in the Indenture.  The
Securities include the Initial Securities and any Exchange Securities issued in
exchange for the Initial Securities pursuant to the Indenture and the
Registration Rights Agreement.  The Initial Securities and the Exchange
Securities are treated as a single class of securities under the Indenture.  The
Indenture imposes certain limitations on:  the Incurrence of Indebtedness by the
Company and its Restricted Subsidiaries, the Incurrence of Indebtedness by the
Company and its Subsidiary Guarantors if subordinate or junior in any respect to
any Senior Indebtedness or Guarantor Senior Indebtedness, respectively, the
payment of dividends and other distributions on the Capital Stock of the Company
and its Restricted Subsidiaries, the purchase or redemption of Capital Stock of
the Company and Capital Stock of such Restricted Subsidiaries, certain purchases
or redemptions of Subordinated Indebtedness, the Incurrence of Liens by the
Company or its Restricted Subsidiaries, the entering into of Asset Swaps by the
Company or its Restricted Subsidiaries, the sale or transfer of assets and
Capital Stock of Restricted Subsidiaries, the issuance or sale of Capital Stock
of Restricted Subsidiaries, the business activities and investments of the
Company and its Restricted Subsidiaries, and transactions with Affiliates.  In
addition, the Indenture limits the ability of the Company and its Subsidiaries
to restrict distributions and dividends from Restricted Subsidiaries.

    To guarantee the due and punctual payment of the principal, premium, if any,
and interest on the Securities and all other amounts payable by the Company
under the Indenture and the Securities when and as the same shall be due and
payable, whether at maturity, by acceleration or otherwise, according to the
terms of the Securities and the Indenture, the Subsidiary Guarantors have
unconditionally guaranteed (and future Subsidiary Guarantors, together with the
Subsidiary Guarantors, will unconditionally guarantee), jointly and severally,
such obligations on a senior subordinated basis pursuant to the terms of the
Indenture.

5.   Optional Redemption
     -------------------

     Except as set forth below, the Securities will not be redeemable at the
option of the Company prior to May 1, 2003. On and after such date, the
Securities will be redeemable, at the Company's option, in whole or in part, at
any time upon not less than 30 nor more than 60 days prior notice mailed by
first-class mail to each holder's registered address, at the following
redemption prices (expressed in percentages of principal amount), plus accrued
and unpaid interest to the redemption date (subject to the right of holders of
record on the relevant record date to receive interest due on the relevant
interest payment date):

     If redeemed during the 12-month period commencing on May 1 of the years set
forth below:

</TABLE>
                                                                                
     In addition, at any time and from time to time prior to  May 1, 2001, the
Company may redeem in the aggregate up to 35% of the original principal amount
of the Securities with the proceeds of one or more Equity Offerings received by,
or invested in, the Company so long as there is a Public Market at the time of
such redemption, at a redemption price (expressed as a percentage of principal
amount) of 109.250% plus accrued and unpaid interest, if any, to the redemption
date (subject to the right of holders of record on the relevant record date to
receive interest due on the relevant interest payment date); provided, however,
that at least 65% of the original principal amount of the Securities must remain
outstanding after each such redemption; provided further, that each such
redemption occurs within 90 days of the date of closing of such Equity Offering.

     At any time on or prior to May 1, 2003, the Securities may also be redeemed
as a whole at the option of the Company upon the occurrence of a Change of
Control, upon not less than 30 nor more than 60 days prior notice (but in no
event more than 30 days after the occurrence of such Change of Control) mailed
by first-class mail to each holder's registered address, at a redemption price
equal to 100% of the principal amount thereof plus the Applicable Premium as of,
and accrued and unpaid interest, if any, to, the date of redemption (the
"Redemption Date") (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date).

     "Applicable Premium" means, with respect to a Security at any Redemption
Date, the greater of (i) 1.0% of the principal amount of such Security and (ii)
the excess of (A) 

                                      B-5
<PAGE>
 
the present value at such time of (1) the redemption price of such Security at
May 1, 2003 (such redemption price being described under "Optional Redemption")
plus (2) all required interest payments due on such Security through May 1,
2003, computed using a discount rate equal to the Treasury Rate plus 50 basis
points, over (B) the principal amount of such Note.

     "Treasury Rate" means the yield to maturity at the time of computation of
United States Treasury securities with a constant maturity (as compiled 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
Redemption Date (or, if such Statistical Release is no longer published, any
publicly available source of similar market data)) most nearly equal to the
period from the Redemption Date to May 1, 2003; provided, however, that if the
period from the Redemption Date to  May 1, 2003 is not equal to the constant
maturity of a United States Treasury security for which a weekly average yield
is given, the Treasury Rate shall 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 such yields are given, except
that if the period from the Redemption Date to May 1, 2003 is less than one
year, the weekly average yield on actually traded United States Treasury
securities adjusted to a constant maturity of one year shall be used.

     In the case of any partial redemption, selection of the Securities for
redemption will be made by the Trustee on a pro rata basis, by lot or by such
other method as the Trustee in its sole discretion shall deem to be fair and
appropriate, although no Securities of $1,000 in original principal amount or
less will be redeemed in part. If any Security is to be redeemed in part only,
the notice of redemption relating to such Security shall state the portion of
the principal amount thereof to be redeemed. A new Security in principal amount
equal to the unredeemed portion thereof will be issued in the name of the holder
thereof upon cancellation of the original Security.

6.   Repurchase Provisions
     ---------------------

          1.  Upon a Change of Control, unless the Company has exercised its
right to redeem the Securities as described under Section 5 hereof, any Holder
of Securities will have the right to cause the Company to repurchase all or any
part of the Securities of such Holder at a purchase price in cash equal to 101%
of the principal amount thereof, plus accrued and unpaid interest, if any, to
the date of repurchase (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date) as provided in, and subject to the terms of, the Indenture.

              (b)  If the Company or a Restricted Subsidiary consummates any
Asset Sales permitted by the Indenture, when the aggregate amount of Excess
Proceeds equals or exceeds $5.0 million, the Company shall make an Offer for all
outstanding Securities pro rata up to a maximum principal amount (expressed as a
multiple of $1,000) of Securities equal to such Excess Proceeds, at a purchase
price in cash equal to 100% of the principal amount thereof, plus accrued and
unpaid interest

                                      B-6
<PAGE>
 
thereon, if any, to the date of purchase in accordance with the procedures set
forth in Section 3.7 of the Indenture.
         -----------                  

7.   Subordination
     -------------

     The Securities are subordinated to Senior Indebtedness and the Note
Guarantees are subordinated to Guarantor Senior Indebtedness, each as defined in
the Indenture. To the extent provided in the Indenture, Senior Indebtedness must
be paid before the Securities may be paid. The Company agrees, and each
Securityholder by accepting a Security agrees, to the subordination provisions
contained in the Indenture and authorizes the Trustee to give them effect and
appoints the Trustee as attorney-in-fact for such purpose. The Securities will
in all respects rank pari passu with all other Senior Subordinated Indebtedness.

8.   Denominations; Transfer; Exchange
     ---------------------------------

     The Securities are in registered form without coupons in denominations of
principal amount of $1,000 and whole multiples of $1,000.  A Holder may transfer
or exchange Securities in accordance with the Indenture.  The Registrar may
require a Holder, among other things, to furnish appropriate endorsements or
transfer documents and to pay any taxes and fees required by law or permitted by
the Indenture.  The Registrar need not register the transfer of or exchange (i)
any Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or for a
period beginning 15 days before the mailing of a notice of Securities to be
redeemed and ending on the date of such mailing or (ii) any Securities for a
period beginning 15 days before an interest payment date and ending on such
interest payment date.

9.   Persons Deemed Owners
     ---------------------

     The registered holder of this Security may be treated as the owner of it
for all purposes.

10.  Unclaimed Money
     ---------------

     If money for the payment of principal or interest remains unclaimed for two
years, the Trustee or Paying Agent shall pay the money back to the Company at
its request unless an abandoned property law designates another person.  After
any such payment, Holders entitled to the money must look only to the Company
and not to the Trustee for payment.

11.  Defeasance
     ----------

     Subject to certain conditions set forth in the Indenture, the Company at
any time may terminate some or all of its obligations under the Securities and
the Indenture if the

                                      B-7
<PAGE>
 
Company deposits with the Trustee money or U.S. Government Obligations for the
payment of principal and interest on the Securities to redemption or maturity,
as the case may be.

12.  Amendment, Waiver
     -----------------

     Subject to certain exceptions set forth in the Indenture, (i) the Indenture
or the Securities may be amended with the written consent of the Holders of at
least a majority in principal amount of the then outstanding Securities and (ii)
any default (other than with respect to nonpayment) or noncompliance with any
provision may be waived with the written consent of the Holders of a majority in
principal amount of the then outstanding Securities. Subject to certain
exceptions set forth in the Indenture, without the consent of any
Securityholder, the Company and the Trustee may amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article IV of the Indenture, or to provide for uncertificated
Securities in addition to or in place of certificated Securities, or to add
guarantees with respect to the Securities or to secure the Securities, or to add
additional covenants or surrender rights and powers conferred on the Company or
Communications or to comply with any request of the SEC in connection with
qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Securityholder, or to provide for the
issuance of Exchange Securities.

13.  Defaults and Remedies
     ---------------------

     Under the Indenture, Events of Default include (i) default for 30 days in
payment of interest when due on the Securities; (ii) default in payment of
principal on the Securities at maturity, upon required repurchase, upon required
repurchase or upon redemption pursuant to paragraphs 5 and 6 of the Securities,
upon declaration or otherwise; (iii) the failure by the Company to comply with
its obligations under Article IV of the Indenture (iv) failure by the Company to
                      ----------                                                
comply for 30 days after notice with any of its obligations under the covenants
described under Section 3.9 of the Indenture or under other covenants specified
                -----------                                                    
in the Indenture (in each case, other than a failure to purchase Securities,
which shall constitute an Event of Default under clause (ii) above), (v) the
failure by the Company to comply for 60 days after notice with its other
agreements contained in the Indenture, (vi) Indebtedness of the Company or any
Restricted Subsidiary if not paid within any applicable grace period after final
maturity or is accelerated by the holders thereof because of a default and the
total amount of such Indebtedness unpaid or accelerated exceeds $5.0 million
(the "cross acceleration provision"), (vii) certain events of bankruptcy,
insolvency or reorganization of the Company or a Significant Subsidiary (the
"bankruptcy provisions"), (viii) any judgment or decree for the payment of money
in excess of $5.0 million is rendered against the Company or a Significant
Subsidiary and such judgment or decree shall remain undischarged or unstayed for
a period of 60 days after such judgment becomes final and non-appealable (the
"judgment default provision") or (ix) any Note Guarantee ceases to be in full
force and effect (except as contemplated by the terms of the Indenture) or any

                                      B-8
<PAGE>
 
Guarantor denies or disaffirms its obligations under the Indenture or its Note
Guarantee.  However, a default under clauses (iv) and (v) will not constitute an
Event of Default until the Trustee or the holders of more than 25% in principal
amount of the outstanding Securities notify the Company of the default and the
Company does not cure such default within the time specified in clauses (iv) and
(v) hereof after receipt of such notice.

     If an Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in principal amount of the Securities may declare all the
Securities to be due and payable immediately. Certain events of bankruptcy or
insolvency are Events of Default which will result in the Securities being due
and payable immediately upon the occurrence of such Events of Default.

     Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in principal amount of the Securities
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from Securityholders notice of any continuing Default or Event of
Default (except a Default or Event of Default in payment of principal or
interest) if it determines that withholding notice is in their interest.

14.  Trustee Dealings with the Company
     ---------------------------------

     Subject to certain limitations set forth in the Indenture, the Trustee
under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or its Affiliates and may otherwise deal
with the Company or its affiliates with the same rights it would have if it were
not Trustee.

15.  No Recourse Against Others
     --------------------------

     An incorporator, director, officer, employee, stockholder or controlling
person, as such, of the Company shall not have any liability for any obligations
of the Company under the Securities or the Indenture or for any claim based on,
in respect of or by reason of such obligations or their creation.  By accepting
a Security, each Securityholder waives and releases all such liability.  The
waiver and release are part of the consideration for the issue of the
Securities.

16.  Authentication
     --------------

     This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent acting on its behalf) manually signs the
certificate of authentication on the other side of this Security.

entirety), JT TEN (=joint tenants with rights of survivorship and not as tenants

18.  CUSIP Numbers
     -------------

     Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is
made as to the accuracy of such numbers either as printed on the Securities or
as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

19.  Governing Law
     -------------

     This Security shall be governed by, and construed in accordance with, the
laws of the State of New York but without giving effect to applicable principles
of conflicts of law to the extent that the application of the laws of another
jurisdiction would be required thereby.

Dear Ladies and Gentlemen:

         We are counsel to Advanstar Communications Inc., a New York corporation
(the "Company") in connection with the registration on a Registration Statement
on Form S-4 (the "Registration Statement") and the prospectus forming a part
thereof (the "Prospectus") under the Securities Act of 1933, as amended, of
$150,000,000 aggregate principal amount of the Company's 9-1/4% Senior
Subordinated Notes due 2008 (the "Exchange Notes") and the related guarantees
(the "Guarantees") of certain of the Company's subsidiaries named in the
Registration Statement (the "Guarantors"). The Exchange Notes and the Guarantees
are proposed to be issued under an indenture dated as of April 30, 1998 (the
"Indenture") between the Company and the Bank of New York, as trustee, and the
related Exchange and Registration Rights Agreement (the "Registration Rights
Agreement"), dated April 30, 1998, among the Company, the Guarantors and the
Initial Purchasers (as defined in the Registration Rights Agreement) in exchange
for the Company's 9-1/4% Senior Subordinated Notes Due 2008 and related
guarantees (the "Original Notes").

         We have examined such documents, records and matters of law as we have
deemed necessary for purposes of this opinion. We have assumed that the Exchange
Notes and the Guarantees will be executed and delivered as set forth in the
Registration Statement, the Prospectus and the Letter of Transmittal set forth
as an exhibit to the Registration Statement. We have assumed the genuineness of
all signatures and the conformity to original documents of all copies of
documents submitted to us as copies, whether certified or not. We have assumed
the conformity of the certificates for the Exchange Notes and the Guarantees to
the specimens of the certificates, which are included as an exhibit to the
Registration Statement. We have assumed that the Exchange Notes, the Guarantees
and the Indenture have been duly authorized, executed and authenticated in
accordance with the terms of the Indenture by each of the parties thereto. Our
opinion expressed herein with respect to the validly and binding effect of the
Exchange Notes and the Guarantees is qualified to the extent that the validity
and binding effect thereof may be limited by (i) applicable bankruptcy,
reorganization, arrangements, insolvency, moratorium or similar laws affecting
the enforcement of creditors' rights generally as at the time in effect and (ii)
general principles of equity (whether considered in a proceeding of law or in
equity).

         We are members only of the bar of the Commonwealth of Massachusetts and
therefore do not hold ourselves out as experts in, and express no opinion as to,
the laws of any other state or

jurisdiction other than the laws of the Commonwealth of Massachusetts and the
federal laws of the United States of America. The Indenture and the Exchange
Notes provide that each is governed by the laws of the State of New York,
without giving effect to the conflict of laws provisions thereof. We have
assumed for purposes of this opinion that the substantive laws of the State of
New York are the same as the substantive laws of the Commonwealth of
Massachusetts. We have also assumed that the choice of law provisions of the
Indenture and the Exchange Notes would be given effect.

         Based upon and subject to the foregoing, we are of the opinion that the
Exchange Notes and the Guarantees, when duly executed and authenticated in
accordance with the terms of the Indenture and delivered in exchange for the
Original Notes as contemplated in the Prospectus, will be valid and binding
obligations of the Company.

         We consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the caption "Legal
Matters" in the Registration Statement.

                                            Very truly yours,

     the Transaction Documents or any action taken or to be taken pursuant
     thereto; and the Company has complied with any and all requests by any

     law, ordinance, governmental rule, regulation or court decree to which it

     all material licenses, certificates, authorizations and permits issued by,
     and have made all declarations and filings with, the appropriate federal,
     state or foreign regulatory agencies or bodies which are necessary or
     desirable for the ownership of their respective properties or the conduct
     of their respective businesses as described in the Offering Memorandum,
     except where the failure to possess or make the same would not, singularly
     or in the aggregate, have a Material Adverse Effect, and none of AHI,
     Holdings, the Company or any of its subsidiaries has received notification
     of any revocation or modification of any such license, certificate,
     authorization or permit or has any reason to believe that any such license,

     have any knowledge of any tax deficiency which, if determined adversely to

     Memorandum; and the conduct of their respective businesses as described in
     the Offering Memorandum will not conflict with, and the Company and its
     subsidiaries have not received any notice of any claim of conflict with,
     any such rights of others, in each case other than such as would not,
     individually or in the aggregate, have a Material Adverse Effect.

          (w)  AHI, Holdings, the Company and each of its subsidiaries have good
     and marketable title in fee simple to, or have valid rights to lease or
     otherwise use, all items of real and personal property which are material

     4975 of the Internal Revenue Code of 1986, as amended from time to time
     (the "Code")) or "accumulated funding deficiency" (as defined in Section
           ----                                                              
     302 of ERISA) or any of the events set forth in Section 4043(b) of ERISA
     (other than events with respect to which the 30-day notice requirement
     under Section 4043 of ERISA has been waived) has occurred with respect to
     any employee benefit plan (other than a multiemployer plan) of AHI,
     Holdings, the Company or any of its subsidiaries which could reasonably be
     expected to have a Material Adverse Effect; each such employee benefit plan
     (other than a multiemployer plan) is in compliance in all material respects
     with applicable law, including ERISA and the Code; AHI, Holdings, the
     Company and each of its subsidiaries have not incurred and do not expect to
     incur liability under Title IV of ERISA with respect to the termination of,
     or withdrawal from, any pension plan for which AHI, Holdings, the Company
     or any of its subsidiaries would have any liability; and each such pension
     plan that is intended to be qualified under Section 401(a) of the Code is
     so qualified in all material respects and nothing has occurred, whether by
     action or by failure to act, which could reasonably be expected to cause
     the loss of such qualification.

          (z)  There has been no storage, generation, transportation, handling,
     treatment, disposal, discharge, emission or other release of any kind of
     toxic or other wastes or other hazardous substances by, due to or caused by

     knowledge of the Company and each Current Guarantor, any other entity
     (including any predecessor) for whose acts or omissions AHI, Holdings, the
     Company or any of its subsidiaries is or could reasonably be expected to be
     liable) upon any of the property now or previously owned or leased by AHI,
     Holdings, the Company or any of its subsidiaries, or upon any other
     property, in violation of any statute or any ordinance, rule, regulation,
     order, judgment, decree or permit or which would, under any statute or any
     ordinance, rule (including rule of common law), regulation, order,
     judgment, decree or permit, give rise to any liability, except for any
     violation or liability which could not reasonably be expected to have,
     singularly or in the aggregate with all such violations and liabilities, a
     Material Adverse Effect; and there has been no disposal, discharge,
     emission or other release of any kind onto such property or into the
     environment surrounding such property of any toxic or other wastes or other
     hazardous substances with respect to which the Company or any Current
     Guarantor has knowledge, except for any such disposal, discharge, emission
     or other release of any kind which could not

                                                                               8

     reasonably be expected to have, singularly or in the aggregate with all
     such discharges and other releases, a Material Adverse Effect.

          (aa)  None of the Company or any Current Guarantor nor, to the best
     knowledge of the Company and each Current Guarantor, any director, officer,
     agent, employee or other person associated with or acting on behalf of the
     Company or any Current Guarantor has (i) used any corporate funds for any
     unlawful contribution, gift, entertainment or other unlawful expense
     relating to political activity; (ii) made any direct or indirect unlawful
     payment to any foreign or domestic government official or employee from
     corporate funds; (iii) violated or is in violation of any provision of the
     Foreign Corrupt Practices Act of 1977; or (iv) made any bribe, rebate,
     payoff, influence payment, kickback or other unlawful payment.

          (bb)  On and immediately after the Closing Date, the Company and
     each Current Guarantor (after giving effect to the issuance of the
     Securities and to the other transactions related thereto as described in
     the Offering Memorandum) will be Solvent.  As used in this paragraph, the
     term "Solvent" with respect to any Person means, with respect to a
     particular date, that on such date (i) the present fair market value (or
     present fair saleable value) of the assets of such Person is not less than
     the total amount required to pay the probable liabilities of such Person on
     its total existing debts and liabilities (including contingent liabilities)
     as they become absolute and matured, (ii) such Person is able to realize
     upon its assets and pay its debts and other liabilities, contingent
     obligations and commitments as they mature and become due in the normal
     course of business, (iii) assuming the sale of the Securities as
     contemplated by this Agreement and the Offering Memorandum, such Person is
     not incurring debts or liabilities beyond its ability to pay as such debts
     and liabilities mature and (iv) such Person is not engaged in any business
     or transaction, and is not about to engage in any business or transaction,
     for which its property would constitute unreasonably small capital after
     giving due consideration to the prevailing practice in the industry in
     which such Person is engaged.  In computing the amount of such contingent
     liabilities at any time, it is intended that such liabilities will be
     computed at the amount that, in the light of all the facts and
     circumstances existing at such time, represents the amount that can
     reasonably be expected to become an actual or matured liability.

          (cc)  Except as described in the Offering Memorandum, there are no
     outstanding material subscriptions, rights, warrants, calls or options to
     acquire, or instruments convertible into or exchangeable for, or agreements
     or understandings with respect to the sale or issuance of, any shares of
     capital stock of or other equity or other ownership interest in AHI,
     Holdings, the Company or any of its subsidiaries.

          (dd)  None of the proceeds of the sale of the Securities will be used,
     directly or indirectly, for the purpose of purchasing or carrying any
     "margin securities" as that term is defined in Regulations G and U of the
     Board of Governors of the Federal Reserve System (the "Federal Reserve
                                                            ---------------
     Board"), for the purpose of reducing or retiring any indebtedness which was
     -----                                                                      
     originally incurred to purchase or carry any margin security or for any
     other purpose which might cause any of the Securities to be considered a
     "purpose credit" within the meanings of Regulation G, T, U or X of the
     Federal Reserve Board.

          (ee)  None of AHI, Holdings, the Company or any of its subsidiaries is
     a party to any contract, agreement or understanding with any person that
     would give rise to a valid claim against the Company, any Current Guarantor
     or the Initial Purchasers for a brokerage commission, finder's fee or like
     payment in connection with the offering and sale of the Securities other
     than this Agreement.

          (ff)  The Securities satisfy the eligibility requirements of Rule
     144A(d)(3) under the Securities Act.

     on its or their behalf has engaged or will engage in any directed selling
     efforts (as such term is defined in Regulation S under the Securities Act
     ("Regulation S")), and all such persons have complied and will comply with
       ------------                                                            
     the offering restrictions requirement of Regulation S to the extent
     applicable.

          (hh)  Neither the Company nor any of its affiliates has, directly or
     through any agent, sold, offered for sale, solicited offers to buy or
     otherwise negotiated in respect of, any security (as such term is defined
     in the Securities Act), which is or will be integrated with the sale of the
     Securities in a manner that would require registration of the Securities
     under the Securities Act.

          (ii)  None of the Company or any of its affiliates or any other person
     acting on its or their behalf has engaged, in connection with the offering
     of the Securities, in any form of general solicitation or general
     advertising within the meaning of Rule 502(c) under the Securities Act.

          (jj)  There are no securities of the Company registered under the
     Exchange Act or listed on a national securities exchange or quoted in a
     U.S. automated inter-dealer quotation system.

          (kk)  The Company has not taken and will not take, directly or
     indirectly, any action prohibited by Regulation M under the Exchange Act in
     connection with the offering of the Securities.

          (ll)  No forward-looking statement (within the meaning of Section 27A
     of the Securities Act and Section 21E of the Exchange Act) contained in the
     Preliminary Offering Memorandum or the Offering Memorandum has been made or
     reaffirmed without a reasonable basis or has been disclosed other than in
     good faith.

     does business with the government of Cuba or with any person or affiliate
     located in Cuba within the meaning of Florida Statutes Section 517.075.

          (nn)  Since the date as of which information is given in the Offering
     Memorandum, except as otherwise stated therein, (i) there has been no
     material adverse change or any development involving a prospective material
     adverse change in the condition, financial or otherwise, or in the
     earnings, business affairs, management or business prospects of the Company
     or any Current Guarantor, whether or not arising in the ordinary course of
     business, (ii) the Company and each Current Guarantor has not incurred any
     material liability or obligation, direct or contingent, other than in the

     other material agreement or instrument to which it is a party or by which
     it is bound or to which any of its property or assets is subject, except

     Adverse Effect, or (iii) in violation of any law, ordinance, governmental

     fact necessary in order to make the statements therein, in the light of the
     circumstances existing at the time it is delivered to a purchaser, not
     misleading, or if it is necessary to amend or supplement the Offering

          (n)  There shall not have occurred any invalidation of Rule 144A under
     the Securities Act by any court or any withdrawal or proposed withdrawal of
     any rule or regulation under the Securities Act or the Exchange Act by the

     which in the reasonable judgment of the Initial Purchasers would materially
     impair the ability of the Initial Purchasers to purchase, hold or effect
     resales of the Securities as contemplated hereby.

     described above, is, in the reasonable judgment of the Initial Purchasers,
     so material and adverse as to make it impracticable or inadvisable to

     manner contemplated by this Agreement and the Offering Memorandum
     (exclusive of any amendment or supplement thereto).

          (p)  No action shall have been taken and no statute, rule, regulation
     or order shall have been enacted, adopted or issued by any United States

     downgrading shall have occurred in the rating accorded the Securities or
     any of the Company's other debt securities or preferred stock by any
     "nationally recognized statistical rating organization", as such term is
     defined by the Commission for purposes of Rule 436(g)(2) of the rules and
     regulations of the Commission under the Securities Act and (ii) no such
     organization shall have publicly announced that it has under surveillance
     or review (other than an announcement with positive implications of a
     possible upgrading), its rating of the Securities or any of the Company's
     other debt securities or preferred stock.

          (r)  Subsequent to the execution and delivery of this Agreement there
     shall not have occurred any of the following: (i) trading in securities

     the over-the-counter market shall have been suspended or limited, or
     minimum prices shall have been established on any such exchange or market
     by the Commission, by any such exchange or by any other regulatory body or
     governmental authority having jurisdiction, or trading in any securities of
     the Company on any exchange or in the over-the-counter market shall have
     been suspended or (ii) any moratorium on commercial banking activities
     shall have been declared by federal or New York state authorities or (iii)
     an outbreak or escalation of hostilities or a declaration by the United
     States of a national emergency or war or (iv) a material adverse change in
     general economic, political or financial conditions (or the effect of
     international conditions on the financial markets in the United States
     shall be such) the effect of which, in the case of this clause (iv), is, in
     the judgment of the Initial Purchasers, so material and adverse as to make
     it impracticable or inadvisable to proceed with the sale or the delivery of
     the Securities on the terms and in the manner contemplated by this
     Agreement and in the Offering Memorandum (exclusive of any amendment or
     supplement thereto).

          (s)  The Initial Purchasers shall have received on the Closing Date an
     Officer's Certificate from Joseph Loggia, President and Chief Executive
     Officer of MAGIC, addressed to the Initial Purchasers and dated the Closing

          All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Initial Purchasers.

may be terminated by the Initial Purchasers, in their absolute discretion, by
notice given to and received by the Company prior to delivery of and payment for
the Securities if, prior to that time, any of the events described in Section
6(m), (n), (o), (p) or (q) shall have occurred and be continuing.

          8.   Defaulting Initial Purchasers.  (a)  If, on the Closing Date, any
               -----------------------------                                    
Initial Purchaser defaults in the performance of its obligations under this
Agreement, the non-defaulting Initial Purchasers may make arrangements for the
purchase of the Securities which such defaulting Initial Purchaser agreed but
failed to purchase by other persons satisfactory to the Company and the non-
defaulting Initial Purchasers, but if no such arrangements are made within 36
hours after such default, this Agreement shall terminate without liability on
the part of the non-defaulting Initial Purchasers, the Company or the
Guarantors, except that the Company will continue to be liable for the payment
of expenses to the extent set forth in Sections 9 and 13 and except that the
provisions of Sections 9 and 10 shall not terminate and shall remain in effect.
As used in this Agreement, the term "Initial Purchasers" includes, for all
purposes of this Agreement unless the context otherwise requires, any party not
listed in Schedule 1 hereto that, pursuant to this Section 8, purchases
Securities which a defaulting Initial Purchaser agreed but failed to purchase.

          (b)  Nothing contained herein shall relieve a defaulting Initial
Purchaser of any liability it may have to the Company or the Current Guarantors
or any non-defaulting Initial Purchaser for damages caused by its default.  If
other persons are obligated or agree to purchase the Securities of a defaulting
Initial Purchaser, either the non-defaulting Initial Purchasers or the Company
may postpone the Closing Date for up to seven full business days in order to
effect any changes that in the opinion of counsel for the Company or counsel for
the Initial Purchasers may be necessary in the Offering Memorandum or in any
other document or arrangement, and the Company agrees to promptly prepare any
amendment or supplement to the Offering Memorandum that effects any such
changes.

          9.   Reimbursement of Initial Purchasers' Expenses.  If (a) this
               ---------------------------------------------              
Agreement shall have been terminated pursuant to Section 7 or 8, (b) the Company
shall fail to tender the Securities for delivery to the Initial Purchasers for
any reason permitted under this Agreement or (c) the Initial Purchasers shall
decline to purchase the Securities for any reason permitted under this
Agreement, the Company shall reimburse the Initial Purchasers for such out-of-
pocket expenses (including reasonable fees and disbursements of counsel) as
shall have been reasonably incurred by the Initial Purchasers in connection with
this Agreement and the proposed purchase and resale of the Securities.  If this
Agreement is terminated pursuant to Section 8 by reason of the default of one or
more of the Initial Purchasers, the Company shall not be obligated to reimburse
any defaulting Initial Purchaser on account of such expenses.

          10.  Indemnification.  (a)  The Company and the Current Guarantors,
               ---------------                                               
jointly and severally, shall indemnify and hold harmless each Initial Purchaser,
its affiliates, their respective officers, directors, employees, representatives
and agents, and each person, if any, who controls any Initial Purchaser within
the meaning of the Securities Act or the Exchange Act (collectively referred to
for purposes of this Section 10(a) and Section 11 as an Initial Purchaser), from
and against any loss, claim, damage or liability, joint or several, or any
action in respect thereof (including, without limitation, any loss, claim,
damage, liability or action relating to purchases and sales of the Securities),
to which that Initial Purchaser may become subject, whether commenced or
threatened, under the Securities Act, the Exchange Act, any other federal or
state statutory law or regulation, at common law or otherwise, insofar as such
loss, claim, damage, liability or action arises out of, or is based upon, (i)
any untrue statement or alleged untrue statement of a material fact contained in
the Preliminary Offering Memorandum or the Offering Memorandum or in any
amendment or supplement thereto 
<PAGE>
 
                                                                              24

or in any information provided by the Company or any Guarantor pursuant to
Section 5(e) or (ii) the omission or alleged omission to state therein a
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, and shall reimburse each Initial Purchaser promptly upon
demand for any legal or other expenses reasonably incurred by that Initial
Purchaser in connection with investigating or defending or preparing to defend
against or appearing as a third party witness in connection with any such loss,
claim, damage, liability or action as such expenses are incurred; provided,
                                                                  --------
however, that the Company and the Guarantors shall not be liable in any such
- -------                                                            
case to the extent that any such loss, claim, damage, liability or action arises
out of, or is based upon, an untrue statement or alleged untrue statement in or
omission or alleged omission from any of such documents in reliance upon and in
conformity with any Initial Purchasers' Information; and provided, further, that
                                                         --------  -------
with respect to any such untrue statement in or omission from the Preliminary
Offering Memorandum, the indemnity agreement contained in this Section 10(a)
shall not inure to the benefit of any such Initial Purchaser to the extent that
the sale to the person asserting any such loss, claim, damage, liability or
action was an initial resale by such Initial Purchaser and any such loss, claim,
damage, liability or action of or with respect to such Initial Purchaser results
from the fact that both (A) to the extent required by applicable law, a copy of
the Offering Memorandum was not sent or given to such person at or prior to the
written confirmation of the sale of such Securities to such person and (B) the
untrue statement in or omission from the Preliminary Offering Memorandum was
corrected in the Offering Memorandum unless, in either case, such failure to
deliver the Offering Memorandum was a result of non-compliance by the Company or
any Current Guarantor with Section 5(b).

          (b)  Each Initial Purchaser, severally and not jointly, shall
indemnify and hold harmless the Company, its affiliates (including the
Guarantors), their respective officers, directors, employees, representatives
and agents, and each person, if any, who controls the Company within the meaning
of the Securities Act or the Exchange Act (collectively referred to for purposes
of this Section 10(b) and Section 11 as the Company), from and against any loss,
claim, damage or liability, joint or several, or any action in respect thereof,
to which the Company or a Guarantor may become subject, whether commenced or
threatened, under the Securities Act, the Exchange Act, any other federal or
state statutory law or regulation, at common law or otherwise, insofar as such
loss, claim, damage, liability or action arises out of, or is based upon, (i)
any untrue statement or alleged untrue statement of a material fact contained in
the Preliminary Offering Memorandum or the Offering Memorandum or in any
amendment or supplement thereto or (ii) the omission or alleged omission to
state therein a material fact required to be stated therein or necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading, but in each case only to the extent that
the untrue statement or alleged untrue statement or omission or alleged omission
was made in reliance upon and in conformity with any Initial Purchasers'
Information, and shall reimburse the Company and the Current Guarantors for any
legal or other expenses reasonably incurred by the Company or the Current
Guarantors in connection with investigating or defending or preparing to defend
against or appearing as a third party witness in connection with any such loss,
claim, damage, liability or action as such expenses are incurred.

          (c)  Promptly after receipt by an indemnified party under this Section
10 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party pursuant to Section 10(a) or 10(b), notify the indemnifying
party in writing of the claim or the commencement of that action; provided,
                                                                  -------- 
however, that the failure to notify the indemnifying party shall not relieve it
- -------                                                                        
from any liability which it may have under this Section 10 except to the extent
that it has been materially prejudiced (such as through the forfeiture of
substantive rights or defenses) by such failure; and, provided, further, that
                                                      --------  -------      
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have to an indemnified party otherwise than under this
Section 10.  If any such claim or action shall be brought against an indemnified
party, and it shall notify the indemnifying party thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it
wishes, jointly with any other similarly notified indemnifying party, to assume
the defense thereof with counsel reasonably satisfactory to the indemnified
party.  After notice from the indemnifying party to the indemnified party of its
<PAGE>
 
                                                                              25

election to assume the defense of such claim or action, the indemnifying party
shall not be liable to the indemnified party under this Section 10 for any legal
or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation; provided,
                                                                       -------- 
however, that an indemnified party shall have the right to employ its own
- -------                                                                  
counsel in any such action, but the fees, expenses and other charges of such
counsel for the indemnified party will be at the expense of such indemnified
party unless (1) the employment of counsel by the indemnified party has been
authorized in writing by the indemnifying party, (2) the indemnified party has
reasonably concluded (based upon advice of counsel to the indemnified party)
that there may be legal defenses available to it or other indemnified parties
that are different from or in addition to those available to the indemnifying
party, (3) a conflict or potential conflict exists (based upon advice of counsel
to the indemnified party) between the indemnified party and the indemnifying
party (in which case the indemnifying party will not have the right to direct
the defense of such action on behalf of the indemnified party) or (4) the
indemnifying party has not in fact employed counsel reasonably satisfactory to
the indemnified party to assume the defense of such action within a reasonable
time after receiving notice of the commencement of the action, in each of which
cases the reasonable fees, disbursements and other charges of counsel will be at
the expense of the indemnifying party or parties.  It is understood that the
indemnifying party or parties shall not, in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for the reasonable fees,
disbursements and other charges of more than one separate firm of attorneys (in
addition to any local counsel) at any one time for all such indemnified party or
parties.  Each indemnified party, as a condition of the indemnity agreements
contained in Sections 10(a) and 10(b), shall use all reasonable efforts to
cooperate with the indemnifying party in the defense of any such action or
claim.  No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any indemnified party from and against any
loss or liability by reason of such settlement or judgment.  No indemnifying
party shall, without the prior written consent of the indemnified party (which
consent shall not be unreasonably withheld), effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such proceeding.

          The obligations of the Company, the Current Guarantors and the Initial
Purchasers in this Section 10 and in Section 11 are in addition to any other
liability that the Company, the Current Guarantors or the Initial Purchasers, as
the case may be, may otherwise have, including in respect of any breaches of
representations, warranties and agreements made herein by any such party.

          11.  Contribution.  If the indemnification provided for in Section 10
               ------------                                                    
is unavailable or insufficient to hold harmless an indemnified party under
Section 10(a) or 10(b), then each indemnifying party shall, in lieu of
indemnifying such indemnified party, contribute to the amount paid or payable by
such indemnified party as a result of such loss, claim, damage or liability, or
action in respect thereof, (i) in such proportion as shall be appropriate to
reflect the relative benefits received by the Company and the Current Guarantors
on the one hand and the Initial Purchasers on the other from the offering of the
Securities or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company and the Current Guarantors on the one hand and the Initial
Purchasers on the other with respect to the statements or omissions that
resulted in such loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant equitable considerations.  The relative benefits
received by the Company and the Current Guarantors on the one hand and the
Initial Purchasers on the other with respect to such offering shall be deemed to
be in the same proportion as the total net proceeds from the offering of the
Securities purchased under this Agreement (before deducting expenses) received
by or on behalf of the Company and the Current Guarantors, on the one hand, and
the total discounts and commissions received by the Initial Purchasers with
respect to the Securities purchased under this Agreement, on the other, bear to
the total gross proceeds from the sale of the Securities under this Agreement,
in each case as set forth in the table on the cover page of the 
<PAGE>
 
                                                                              26

Offering Memorandum. The relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to the
Company or any Current Guarantor or information supplied by the Company or any
Current Guarantors on the one hand or to any Initial Purchasers' Information on
the other, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such untrue statement or
omission. The Company and the Current Guarantors and the Initial Purchasers
agree that it would not be just and equitable if contributions pursuant to this
Section 11 were to be determined by pro rata allocation (even if the Initial
Purchasers were treated as one entity for such purpose) or by any other method
of allocation that does not take into account the equitable considerations
referred to herein. The amount paid or payable by an indemnified party as a
result of the loss, claim, damage or liability, or action in respect thereof,
referred to above in this Section 11 shall be deemed to include, for purposes of
this Section 11, any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending or preparing to
defend any such action or claim. Notwithstanding the provisions of this Section
11, no Initial Purchaser shall be required to contribute any amount in excess of
the amount by which the total discounts and commissions received by such Initial
Purchaser with respect to the Securities purchased by it under this Agreement
exceeds the amount of any damages which such Initial Purchaser has otherwise
paid or become liable to pay by reason of any untrue or alleged untrue statement
or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Initial Purchasers' obligations to contribute
as provided in this Section 11 are several in proportion to their respective
purchase obligations and not joint.

          12.  Persons Entitled to Benefit of Agreement.  This Agreement shall
               ----------------------------------------                       
inure to the benefit of and be binding upon the Initial Purchasers, the Company
and the Current Guarantors and their respective successors.  This Agreement and
the terms and provisions hereof are for the sole benefit of only those persons,
except as provided in Sections 10 and 11 with respect to affiliates, officers,
directors, employees, representatives, agents and controlling persons of the
Company, the Current Guarantors and the Initial Purchasers.  Nothing in this
Agreement is intended or shall be construed to give any person, other than the
persons referred to in this Section 12, any legal or equitable right, remedy or
claim under or in respect of this Agreement or any provision contained herein.

          13.  Expenses.  The Company agrees with the Initial Purchasers to pay
               --------                                                        
(a) the costs incident to the authorization, issuance, sale, preparation and
delivery of the Securities and any taxes payable in that connection; (b) the
costs incident to the preparation, printing and distribution of the Preliminary
Offering Memorandum, the Offering Memorandum and any amendments or supplements
thereto; (c) the costs of reproducing and distributing each of the Transaction
Documents; (d) the costs incident to the preparation, printing and delivery of
the certificates evidencing the Securities, including stamp duties and transfer
taxes, if any, payable upon issuance of the Securities; (e) the fees and
expenses of the Company's counsel and independent accountants; (f) the fees and
expenses of qualifying the Securities under the securities laws of the several
jurisdictions as provided in Section 5(h) and of preparing, printing and
distributing Blue Sky Memoranda (including related fees and expenses of counsel
for the Initial Purchasers); (g) any fees charged by rating agencies for rating
the Securities; (h) the fees and expenses of the Trustee and any paying agent
(including related fees and expenses of any counsel to such parties); (i) all
expenses and application fees incurred in connection with the application for
the inclusion of the Securities on the PORTAL Market and the approval of the
Securities for book-entry transfer by DTC; and (j) all other costs and expenses
incident to the performance of the obligations of the Company and the Guarantors
under this Agreement which are not otherwise specifically provided for in this
Section 13; provided, however, that except as provided in this Section 13 and
            --------  -------                                                
Section 9, the Initial Purchasers shall pay their own costs and expenses.

          14.  Survival.  The respective indemnities, rights of contribution,
               --------                                                      
representations, warranties and agreements of the Company, the Current
Guarantors and the Initial Purchasers contained in this  Agreement or made by or
on behalf of the Company, the Current Guarantors or the Initial Purchasers
pursuant 
<PAGE>
 
                                                                              27

to this Agreement or any certificate delivered pursuant hereto shall survive the
delivery of and payment for the Securities and shall remain in full force and
effect, regardless of any termination or cancellation of this Agreement or any
investigation made by or on behalf of any of them or any of their respective
affiliates, officers, directors, employees, representatives, agents or
controlling persons.

          15.  Notices, etc.  All statements, requests, notices and agreements
               -------------

also be delivered or sent by mail to such Initial Purchaser at its address set

by CSI.

          16.  Definition of Terms.  For purposes of this Agreement, (a) the

"Purchase Agreement"), $150,000,000 aggregate principal amount of its 9 1/4%
 ------------------
Senior Subordinated Notes due 2008 (the "Notes"), which Notes will be
                                         -----
unconditionally guaranteed (the "Guarantees", and, together with the Notes, the
                                 ----------
"Securities"), on a senior subordinated basis, by (i) each subsidiary of the

          As an inducement to the Initial Purchasers to enter into the Purchase
Agreement and in satisfaction of a condition to the obligations of the Initial
Purchasers thereunder, the Company and each Guarantor agrees with the Initial
Purchasers, for the benefit of the holders (including the Initial Purchasers) of
the Securities, the Exchange Securities (as defined herein) and the Private
Exchange Securities (as defined herein) (collectively, the "Holders"), as
                                                            -------

statement (the "Exchange Offer Registration Statement") on an appropriate form
                -------------------------------------                         
under the Securities Act with respect to a proposed offer to the Holders of the
Securities (the "Registered Exchange Offer") to issue and deliver to such
                 -------------------------                               
Holders, in exchange for 
<PAGE>
 
                                                                               2



the Securities, a like aggregate principal amount of debt securities of the
Company unconditionally guaranteed, on a senior subordinated basis, by the
Guarantors (the "Exchange Securities") that are identical in all material
                 -------------------
respects to the Securities, except for the transfer restrictions relating to the
Securities, (ii) use its reasonable best efforts to cause the Exchange Offer
Registration Statement to become effective under the Securities Act no later
than 150 days after the Issue Date and the Registered Exchange Offer to be
consummated no later than 185 days after the Issue Date and (iii) keep the
Exchange Offer Registration Statement effective for not less than 30 days (or
longer, if required by applicable law) after the date on which notice of the
Registered Exchange Offer is mailed to the Holders (such period being called the
"Exchange Offer Registration Period"). The Exchange Securities will be issued
 ----------------------------------
under the Indenture or an indenture (the "Exchange Securities Indenture") among
                                          -----------------------------
the Company, the Guarantors and the Trustee or such other bank or trust company
that is reasonably satisfactory to the Initial Purchasers, as trustee (the
"Exchange Securities Trustee"), such indenture to be identical in all material
 ---------------------------
respects to the Indenture, except for the transfer restrictions relating to the
Securities (as described above).

          Upon the effectiveness of the Exchange Offer Registration Statement,
the Company shall promptly commence the Registered Exchange Offer, it being the
objective of such Registered Exchange Offer to enable each Holder electing to
exchange Securities for Exchange Securities (assuming that such Holder (a) is
not an affiliate of the Company or an Exchanging Dealer (as defined herein) not
complying with the requirements of the next sentence, (b) acquires the Exchange
Securities in the ordinary course of such Holder's business and (c) has no
arrangements or understandings with any person to participate in the
distribution of the Exchange Securities) and to trade such Exchange Securities
from and after their receipt without any limitations or restrictions under the
Securities Act and without material restrictions under the securities laws of
the several states of the United States.  The Company, the Guarantors, the
Initial Purchasers and each Exchanging Dealer acknowledge that, pursuant to
current interpretations by the Commission's staff of Section 5 of the Securities
Act, each Holder that is a broker-dealer electing to exchange Securities,
acquired for its own account as a result of market-making activities or other
trading activities, for Exchange Securities (an "Exchanging Dealer"), is
                                                 -----------------      
required to deliver a prospectus containing substantially the information set
forth in Annex A hereto on the cover, in Annex B hereto in the "Exchange Offer
Procedures" section and the "Purpose of the Exchange Offer" section and in Annex
C hereto in the "Plan of Distribution" section of such prospectus in connection
with a sale of any such Exchange Securities received by such Exchanging Dealer
pursuant to the Registered Exchange Offer.

          If, prior to the consummation of the Registered Exchange Offer, any
Holder holds any Securities acquired by it that have, or that are reasonably
likely to be determined to have, the status of an unsold allotment in an initial
distribution, or any Holder is not entitled to participate in the Registered
Exchange Offer, the Company shall, upon the request of any such Holder,
simultaneously with the delivery of the Exchange Securities in the Registered
Exchange Offer, issue and deliver to any such Holder, in exchange for the
Securities held by such Holder (the "Private Exchange"), a like aggregate
                                     ----------------                    
principal amount of debt securities of the Company guaranteed by the Guarantors
(the "Private Exchange Securities") that are identical in all material respects
      ---------------------------                                              
to the Exchange Securities, except for the transfer restrictions relating to
such Private Exchange Securities.  The Private Exchange 
<PAGE>
 
                                                                               3

Securities will be issued under the same indenture as the Exchange Securities,
and the Company shall use its reasonable best efforts to cause the Private
Exchange Securities to bear the same CUSIP number as the Exchange Securities.

          In connection with the Registered Exchange Offer, the Company and the
Guarantors shall:

               (a)  mail to each Holder a copy of the prospectus forming part of
     the Exchange Offer Registration Statement, together with an appropriate
     letter of transmittal and related documents;

               (b)  keep the Registered Exchange Offer open for not less than 30
     days (or longer, if required by applicable law) after the date on which
     notice of the Registered Exchange Offer is mailed to the Holders;

               (c)  utilize the services of a depositary for the Registered
     Exchange Offer with an address in the Borough of Manhattan, The City of New
     York;

               (d)  permit Holders to withdraw tendered Securities at any time
     prior to the close of business, New York City time, on the last business
     day on which the Registered Exchange Offer shall remain open; and

               (e)  otherwise comply in all respects with all laws that are
     applicable to the Registered Exchange Offer.

          As soon as practicable after the close of the Registered Exchange
Offer and any Private Exchange, as the case may be, the Company and the
Guarantors shall:

          (a)  accept for exchange all Securities tendered and not validly
     withdrawn pursuant to the Registered Exchange Offer and the Private
     Exchange;

          (b)  deliver to the Trustee for cancellation all Securities so
     accepted for exchange; and

          (c)  cause the Trustee or the Exchange Securities Trustee, as the case
     may be, promptly to authenticate and deliver to each Holder, Exchange
     Securities or Private Exchange Securities, as the case may be, equal in
     principal amount to the Securities of such Holder so accepted for exchange.

          The Company and the Guarantors shall use their reasonable best efforts
to keep the Exchange Offer Registration Statement effective and to amend and
supplement the prospectus contained therein in order to permit such prospectus
to be used by all persons subject to the prospectus delivery requirements of the
Securities Act for such period of time as such persons must comply with such
requirements in order to resell the Exchange Securities; provided that (i) in
                                                         --------            
the case where such prospectus and any amendment or supplement thereto must be
delivered by an Exchanging Dealer, such period shall be the lesser of 180 days
and the date on which all Exchanging Dealers have sold all Exchange Securities
held by them and (ii) the Company and the Guarantors shall make such

                                                                               4

prospectus and any amendment or supplement thereto available to any broker-
dealer for use in connection with any resale of any Exchange Securities for a
period of not less than 90 days after the consummation of the Registered
Exchange Offer.

          The Indenture or the Exchange Securities Indenture, as the case may
be, shall provide that the Securities, the Exchange Securities and the Private
Exchange Securities shall vote and consent together on all matters as one class
and that none of the Securities, the Exchange Securities or the Private Exchange
Securities will have the right to vote or consent as a separate class on any
matter.

          Interest on each Exchange Security and Private Exchange Security
issued pursuant to the Registered Exchange Offer and in the Private Exchange
will accrue from the last interest payment date on which interest was paid on
the Securities surrendered in exchange therefor or, if no interest has been paid
on the Securities, from the Issue Date.

          Each Holder participating in the Registered Exchange Offer shall be
required to represent to the Company that at the time of the consummation of the
Registered Exchange Offer (i) any Exchange Securities received by such Holder
will be acquired in the ordinary course of business, (ii) such Holder will have
no arrangements or understanding with any person to participate in the
distribution of the Securities or the Exchange Securities within the meaning of
the Securities Act and (iii) such Holder is not an affiliate of the Company or,
if it is such an affiliate, such Holder will comply with the registration and
prospectus delivery requirements of the Securities Act to the extent applicable.

          Notwithstanding any other provisions hereof, the Company and the
Guarantors will ensure that (i) any Exchange Offer Registration Statement and
any amendment thereto and any prospectus forming part thereof and any supplement
thereto complies in all material respects with the Securities Act and the rules
and regulations of the Commission thereunder, (ii) any Exchange Offer
Registration Statement and any amendment thereto does not, when it becomes
effective, contain an untrue statement of a material fact or omit to state a

therein not misleading and (iii) any prospectus forming part of any Exchange
Offer Registration Statement, and any supplement to such prospectus, does not,
as of the consummation of the Registered Exchange Offer, include an untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading.

          2.   Shelf Registration.  If (i) because of any change in law or
               ------------------                                         
applicable interpretations thereof by the Commission's staff the Company and the
Guarantors are not permitted to effect the Registered Exchange Offer as
contemplated by Section 1 hereof, or (ii) for any other reason the Registered
Exchange Offer is not consummated within 185 days after the Issue Date, or (iii)
any Initial Purchaser so requests with respect to Securities or Private Exchange
Securities not eligible to be exchanged for Exchange Securities in the
Registered Exchange Offer and held by it following the consummation of the
Registered Exchange Offer, or (iv) any Holder so requests because any applicable
law or interpretations do not permit such Holder to participate in the

                                                                               5

Securities in exchange for tendered Securities, or (vi) the Company so elects,
then the following provisions shall apply:

          (a)  The Company and the Guarantors shall use their reasonable best
efforts to file as promptly as practicable (but in no event more than 45 days
after so required or requested pursuant to this Section 2) with the Commission,
and thereafter shall use their reasonable best efforts to cause to be declared
effective, a shelf registration statement on an appropriate form under the
Securities Act relating to the offer and sale of the Transfer Restricted
Securities by the Holders thereof from time to time in accordance with the
methods of distribution set forth in such registration statement (hereafter, a
"Shelf Registration Statement" and, together with any Exchange Offer
 ----------------------------                                       
Registration Statement, a "Registration Statement").
                           ----------------------   

          (b)  The Company and the Guarantors shall use their reasonable best
efforts to keep the Shelf Registration Statement continuously effective in order
to permit the prospectus forming part thereof to be used by Holders of Transfer
Restricted Securities for a period of two years from the Issue Date or such
shorter period that will terminate when all the Transfer Restricted Securities
covered by the Shelf Registration Statement have been sold pursuant thereto (in
any such case, such period being called the "Shelf Registration Period").  The
                                             -------------------------        
Company and the Guarantors shall be deemed not to have used their reasonable
best efforts to keep the Shelf Registration Statement effective during the
requisite period if any of them voluntarily takes any action (other than any
action permitted by this Agreement in connection with a Suspension) that would
result in Holders of Transfer Restricted Securities covered thereby not being
able to offer and sell such Transfer Restricted Securities during that period,
unless such action is required by applicable law.

          (c)  Notwithstanding any other provisions hereof, the Company will
ensure that (i) any Shelf Registration Statement and any amendment thereto and
any prospectus forming part thereof and any supplement thereto complies in all
material respects with the Securities Act and the rules and regulations of the
Commission thereunder, (ii) any Shelf Registration Statement and any amendment
thereto (in either case, other than with respect to information included therein
in reliance upon or in conformity with written information furnished to the
Company and the Guarantors by or on behalf of any Holder specifically for use
therein (the "Holders' Information")) does not, when it becomes effective,
              --------------------                                        
contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading and (iii) any prospectus forming part of any Shelf Registration
Statement, and any supplement to such prospectus (in either case, other than
with respect to Holders' Information), does not include an untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

          3.   Liquidated Damages.  (a)  The parties hereto agree that the
               ------------------                                         
Holders of Transfer Restricted Securities will suffer damages if the Company and
the Guarantors fail to fulfill its obligations under Section 1 or Section 2, as
applicable, and that it would not be feasible to ascertain the extent of such
damages.  Accordingly, if (i) the applicable Registration Statement is not filed
with the Commission on or prior to 60 days after the Issue Date, (ii) the
Exchange Offer Registration Statement or the Shelf Registration Statement, as
the case may be, is 
<PAGE>
 
                                                                               6

not declared effective within 150 days after the Issue Date (or in the case of a
Shelf Registration Statement required to be filed in response to a change in law
or the applicable interpretations of Commission's staff, if later, within 45
days after publication of the change in law or interpretation or, in the case of
clauses (iv) and (v) of the first paragraph of Article 2, within 45 days of the
receipt of a request from a Holder), (iii) the Registered Exchange Offer is not
consummated on or prior to 185 days after the Issue Date, or (iv) the Shelf
Registration Statement is filed and declared effective within 150 days after the
Issue Date (or in the case of a Shelf Registration Statement required to be
filed in response to a change in law or the applicable interpretations of
Commission's staff, if later, within 45 days after publication of the change in
law or interpretation) but shall thereafter cease to be effective (at any time
that the Company and the Guarantors are obligated to maintain the effectiveness
thereof) without being succeeded within 45 days by an additional Registration
Statement filed and declared effective (each such event referred to in clauses
(i) through (iv), a "Registration Default"; provided, that a Suspension (as
                     --------------------
defined) shall not in any event constitute a Registration Default), the Company
will be obligated to pay liquidated damages to each Holder of Transfer
Restricted Securities, during the period of one or more such Registration
Defaults, in an amount equal to $ 0.192 per week per $1,000 principal amount of
Transfer Restricted Securities held by such Holder until (i) the applicable
Registration Statement is filed, (ii) the Exchange Offer Registration Statement
is declared effective and the Registered Exchange Offer is consummated, (iii)
the Shelf Registration Statement is declared effective or (iv) the Shelf
Registration Statement again becomes effective, as the case may be. Following
the cure of all Registration Defaults, the accrual of liquidated damages will
cease. As used herein, the term "Transfer Restricted Securities" means (i) each
                                 ------------------------------
Security until the date on which such Security has been exchanged for a freely
transferable Exchange Security in the Registered Exchange Offer, (ii) each
Security or Private Exchange Security until the date on which it has been
effectively registered under the Securities Act and disposed of in accordance
with the Shelf Registration Statement or (iii) each Security or Private Exchange
Security until the date on which it is distributed to the public pursuant to
Rule 144 under the Securities Act or is saleable pursuant to Rule 144(k) under
the Securities Act. Notwithstanding anything to the contrary in this Section
3(a), the Company shall not be required to pay liquidated damages to a Holder of
Transfer Restricted Securities if such Holder failed to comply with its
obligations to make the representations set forth in the second to last
paragraph of Section 1 or failed to provide the information required to be
provided by it, if any, pursuant to Section 4(n).

          (b)  The Company and the Guarantors shall notify the Trustee and the
Paying Agent under the Indenture immediately upon the happening of each and
every Registration Default.  The Company shall pay the liquidated damages due on
the Transfer Restricted Securities by depositing with the Paying Agent (which
may not be the Company or a Guarantor for these purposes), in trust, for the
benefit of the Holders thereof, prior to 10:00 a.m., New York City time, on the
next interest payment date specified by the Indenture and the Securities, sums
sufficient to pay the liquidated damages then due.  The liquidated damages due
shall be payable on each interest payment date specified by the Indenture and
the Securities to the record holder entitled to receive the interest payment to
be made on such date.  Each obligation to pay liquidated damages shall be deemed
to accrue from and including the date of the applicable Registration Default.

          (c)  The parties hereto agree that the liquidated damages provided for
in this Section 3 constitute a reasonable estimate of and are intended to
constitute the sole damages that will be suffered by Holders of Transfer
Restricted Securities by reason of the failure of (i) the Shelf Registration
Statement or the Exchange Offer Registration Statement to be filed, (ii) the
Shelf Registration Statement to remain effective or (iii) the Exchange Offer
Registration Statement to be declared effective and the Registered Exchange
Offer to be consummated, in each case to the extent required by this Agreement.

          4.   Registration Procedures.  In connection with any Registration
               -----------------------                                      
Statement, the following provisions shall apply:

          (a)  The Company and the Guarantors shall (i) furnish to each Initial

Statement.

          (b)  The Company and the Guarantors shall advise each Initial
Purchaser, each Exchanging Dealer and the Holders (if applicable) and, if
requested by any such person, confirm such advice in writing (which advice
pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction to
suspend the use of the prospectus until the requisite changes have been made):

          (i)   when any Registration Statement and any amendment thereto has
been filed with the Commission and when such Registration Statement or any post-
effective amendment thereto has become effective;

          (ii)  of any request by the Commission for amendments or supplements
to any Registration Statement or the prospectus included therein or for
additional information;

          (iii) of the issuance by the Commission of any stop order suspending

          (iv)  of the receipt by the Company of any notification with respect
to the suspension of the qualification of the Securities, the Exchange
Securities or the Private Exchange Securities for sale in any jurisdiction or

          (v)   of the happening of any event that requires the making of any
changes in any Registration Statement or the prospectus included therein in
order 
<PAGE>
 
                                                                               8

that the statements therein are not misleading and do not omit to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading.

          (c)  The Company and the Guarantors will make every reasonable effort
to obtain the withdrawal at the earliest possible time of any order suspending
the effectiveness of any Registration Statement.

          (d)  The Company and the Guarantors will furnish to each Holder of
Transfer Restricted Securities included within the coverage of any Shelf
Registration Statement, without charge, at least one conformed copy of such
Shelf Registration Statement and any post-effective amendment thereto, including
financial statements and schedules and, if any such Holder so requests in
writing, all exhibits thereto (including those, if any, incorporated by
reference).

          (e)  The Company and the Guarantors will, during the Shelf
Registration Period, promptly deliver to each Holder of Transfer Restricted
Securities included within the coverage of any Shelf Registration Statement,
without charge, as many copies of the prospectus (including each preliminary
prospectus) included in such Shelf Registration Statement and any amendment or
supplement thereto as such Holder may reasonably request; and the Company
consents to the use of such prospectus or any amendment or supplement thereto by
each of the selling Holders of Transfer Restricted Securities in connection with
the offer and sale of the Transfer Restricted Securities covered by such
prospectus or any amendment or supplement thereto.

          (f)  The Company and the Guarantors will furnish to each Initial
Purchaser and each Exchanging Dealer, and to any other Holder who so requests,
without charge, at least one conformed copy of the Exchange Offer Registration
Statement and any post-effective amendment thereto, including financial
statements and schedules and, if any Initial Purchaser or Exchanging Dealer or
any such Holder so requests in writing, all exhibits thereto (including those,
if any, incorporated by reference).

          (g)  The Company and the Guarantors will, during the Exchange Offer
Registration Period or the Shelf Registration Period, as applicable, promptly
deliver to each Initial Purchaser, each Exchanging Dealer and such other persons
that are required to deliver a prospectus following the Registered Exchange

or other persons may reasonably request; and the Company and each Guarantor
consents to the use of such prospectus or any amendment or supplement thereto by
any such Initial Purchaser, Exchanging Dealer or other persons, as applicable,
as aforesaid.

          (h)  Prior to the effective date of any Registration Statement, the
Company and the Guarantors will use their reasonable best efforts to register or
qualify, or cooperate with the Holders of Securities, Exchange Securities or
Private Exchange Securities included therein and their respective counsel in
connection with the registration or qualification of, such Securities, Exchange
Securities or Private Exchange Securities for offer and sale under the
securities or blue sky laws 
<PAGE>
 
                                                                               9

of such United States jurisdictions as any such Holder reasonably requests in
writing and do any and all other acts or things necessary or advisable to enable
the offer and sale in such jurisdictions of the Securities, Exchange Securities
or Private Exchange Securities covered by such Registration Statement; provided
                                                                       --------
that the Company and each Guarantor will not be required to qualify generally to
do business in any jurisdiction where it is not then so qualified or to take any
action which would subject it to general service of process or to taxation in
any such jurisdiction where it is not then so subject.

          (i)  The Company and the Guarantors will cooperate with the Holders
of Securities, Exchange Securities or Private Exchange Securities to facilitate
the timely preparation and delivery of certificates representing Securities,
Exchange Securities or Private Exchange Securities to be sold pursuant to any
Registration Statement free of any restrictive legends and in such denominations
and registered in such names as the Holders thereof may request in writing prior
to sales of Securities, Exchange Securities or Private Exchange Securities
pursuant to such Registration Statement.

          (j)  If any event contemplated by Section 4(b)(ii) through (v) occurs
during the period for which the Company and the Guarantors are required to
maintain an effective Registration Statement, the Company and the Guarantors
will promptly prepare and file with the Commission a post-effective amendment to
the Registration Statement or a supplement to the related prospectus or file any
other required document so that, as thereafter delivered to purchasers of the
Securities, Exchange Securities or Private Exchange Securities from a Holder,
the prospectus will not include an untrue statement of a material fact or omit
to state a material fact necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not misleading.
Notwithstanding anything to the contrary contained in this Agreement, the
Company may issue a notice (a "Suspension Notice") to the Holders stating that a
Shelf Registration Statement may not be used; a Suspension Notice may be given
by the Company pending the announcement of material information by the Company
which the Board of Directors of the Company has determined, based upon an
opinion of counsel, would be required to be disclosed in such Registration
Statement in order to make the statements therein not misleading, and may issue
any Suspension Notice suspending use of the Shelf Registration Statement
required under applicable securities laws to be issued (a "Suspension").  In the
event that the aggregate number of days in any consecutive twelve-month period
for which all such Suspension Notices are issued and effective exceeds 45 days
in the aggregate, then the Company will be obligated to pay liquidated damages
to each Holder of Transfer Restricted Securities, during the period of one or
more such Suspension, in an amount equal to $0.192 per week per $1,000 principal
amount of Transfer Restricted Securities held by such Holder.

          (k)  Not later than the effective date of the applicable Registration
Statement, the Company and the Guarantors will provide a CUSIP number for the
Securities, the Exchange Securities and the Private Exchange Securities, as the
case may be, and provide the applicable trustee with printed certificates for

          (l)  The Company and the Guarantors will comply with all applicable
rules and regulations of the Commission and will make generally available to its
security holders as soon as practicable after the effective date of the
applicable Registration Statement an earning statement satisfying the provisions
of Section 11(a) of the Securities Act; provided that in no event shall such

          (m)  The Company and the Guarantors will cause the Indenture or the
Exchange Securities Indenture, as the case may be, to be qualified under the

Transfer Restricted Securities to be registered pursuant to any Shelf
Registration Statement to furnish to the Company and the Guarantors such
information concerning the Holder and the distribution of such Transfer
Restricted Securities as the Company and the Guarantors may from time to time
reasonably require for inclusion in such Shelf Registration Statement, and the
Company and the Guarantors may exclude from such registration the Transfer
Restricted Securities of any Holder that fails to furnish such information
within a reasonable time after receiving such request.

          (o)  In the case of a Shelf Registration Statement, each Holder of
Transfer Restricted Securities to be registered pursuant thereto agrees by
acquisition of such Transfer Restricted Securities that, upon receipt of any
notice from the Company pursuant to Section 4(b)(ii) through (v) or upon receipt
of a Suspension Notice, such Holder will discontinue disposition of such
Transfer Restricted Securities until such Holder's receipt of copies of the
supplemental or amended prospectus contemplated by Section 4(j) or until advised
in writing (the "Advice") by the Company and the Guarantors that the use of the

give any notice under Section 4(b)(ii) through (v) or give any Suspension Notice
during the period that the Company is required to maintain an effective
Registration Statement (the "Effectiveness Period"), such Effectiveness Period
                             --------------------

the date of the giving of such notice or Suspension Notice, as the case may be,
to and including the date when each seller of Transfer Restricted Securities
covered by such Registration Statement shall have received (x) the copies of the
supplemental or amended prospectus contemplated by Section 4(j) (if an amended
or supplemental prospectus is required) or (y) the Advice (if no amended or
supplemental prospectus is required).

          (p)  In the case of a Shelf Registration Statement, the Company and
the Guarantors shall enter into such customary agreements (including, if
requested, an underwriting agreement in customary form) and take all such other
action, if any, as Holders of a majority in aggregate principal amount of the
Securities, Exchange Securities and Private Exchange Securities being sold or
the managing underwriters (if any) shall reasonably request in order to

from any of such documents in reliance upon and in conformity with any Holders'
Information; and provided, further, that with respect to any such untrue
                 --------  -------
statement in or omission from any related preliminary prospectus, the indemnity
agreement contained in this Section 6(a) shall not inure to the benefit of any
Holder from whom the person asserting any such loss, claim, damage, liability or
action received Securities, Exchange Securities or Private Exchange Securities
to the extent that such loss, claim, damage, liability or action of or with
respect to such Holder results from the fact that both (A) a copy of the final
prospectus was not sent or given to such person at or prior to the written
confirmation of the sale of such Securities, Exchange Securities or Private
Exchange Securities to such person and (B) the untrue statement in or omission
from the related preliminary prospectus was corrected in the final prospectus
unless, in either case, such failure to deliver the final prospectus was a
result of non-compliance by the Company or a Guarantor with Section 4(d), 4(e),
4(f) or 4(g).

          (b)  In the event of a Shelf Registration Statement, each Holder shall
indemnify and hold harmless the Company, its affiliates (including the
Guarantors), their respective officers, directors, employees, representatives
and agents, and each person, if any, who controls the Company within the meaning
of the Securities Act or the Exchange Act (collectively referred to for purposes
of this Section 6(b) and Section 7 as the Company), from and against any loss,
claim, damage or liability, joint or several, or any action in respect thereof,
to which the Company or a Guarantor may become subject, whether commenced or
threatened, under the Securities Act, the Exchange Act, any other federal or
state statutory law or regulation, at common law or otherwise, insofar as such
loss, claim, damage, liability or action arises out of, or is based upon, (i)
any untrue statement or alleged untrue statement of a material fact contained in
any such Registration Statement or any prospectus forming part thereof or in any
amendment or supplement thereto or (ii) the omission or alleged omission to
state therein a material fact required to be stated therein or necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading, but in each case only to the extent that
the untrue statement or alleged untrue statement or omission or alleged omission
was made in reliance upon and in conformity with any Holders' Information
furnished to the Company and the Guarantors by such Holder, and shall reimburse
the Company and the Guarantors for any legal or other expenses reasonably
incurred by the Company and the Guarantors in connection with investigating or
defending or preparing to defend against or appearing as a third party witness
in connection with any such loss, claim, damage, liability or

                                                                              13

action as such expenses are incurred; provided, however, that no such Holder
                                      --------  -------
shall be liable for any indemnity claims hereunder in excess of the amount of
net proceeds received by such Holder from the sale of Securities, Exchange
Securities or Private Exchange Securities pursuant to such Shelf Registration
Statement.

          (c)  Promptly after receipt by an indemnified party under this Section
6 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party pursuant to Section 6(a) or 6(b), notify the indemnifying
party in writing of the claim or the commencement of that action; provided,
                                                                  -------- 
however, that the failure to notify the indemnifying party shall not relieve it
- -------                                                                        
from any liability which it may have under this Section 6 except to the extent
that it has been materially prejudiced (through the forfeiture of substantive
rights or defenses) by such failure; and provided, further, that the failure to
                                         --------  -------                     
notify the indemnifying party shall not relieve it from any liability which it
may have to an indemnified party otherwise than under this Section 6.  If any
such claim or action shall be brought against an indemnified party, and it shall
notify the indemnifying party thereof, the indemnifying party shall be entitled
to participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party.  After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 6 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than the reasonable costs of investigation; provided, however,
                                                          --------  ------- 
that an indemnified party shall have the right to employ its own counsel in any
such action, but the fees, expenses and other charges of such counsel for the
indemnified party will be at the expense of such indemnified party unless (1)
the employment of counsel by the indemnified party has been authorized in
writing by the indemnifying party, (2) the indemnified party has reasonably
concluded (based upon advice of counsel to the indemnified party) that there may
be legal defenses available to it or other indemnified parties that are
different from or in addition to those available to the indemnifying party, (3)
a conflict or potential conflict exists (based upon advice of counsel to the
indemnified party) between the indemnified party and the indemnifying party (in
which case the indemnifying party will not have the right to direct the defense
of such action on behalf of the indemnified party) or (4) the indemnifying party
has not in fact employed counsel reasonably satisfactory to the indemnified
party to assume the defense of such action within a reasonable time after
receiving notice of the commencement of the action, in each of which cases the
reasonable fees, disbursements and other charges of counsel will be at the
expense of the indemnifying party or parties.  It is understood that the
indemnifying party or parties shall not, in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for the reasonable fees,
disbursements and other charges of more than one separate firm of attorneys (in
addition to any local counsel) at any one time for all such indemnified party or
parties.  Each indemnified party, as a condition of the indemnity agreements
contained in Sections 6(a) and 6(b), shall use all reasonable efforts to
cooperate with the indemnifying party in the defense of any such action or
claim.  No indemnifying party shall be liable for any settlement of any such
action effected without its written consent (which consent shall not be
unreasonably withheld), but if settled with its written consent or if there be a
final judgment for the plaintiff in any such action, the indemnifying party
agrees to indemnify and hold harmless any 
<PAGE>
 
                                                                              14

indemnified party from and against any loss or liability by reason of such
settlement or judgment. No indemnifying party shall, without the prior written
consent of the indemnified party (which consent shall not be unreasonably
withheld), effect any settlement of any pending or threatened proceeding in
respect of which any indemnified party is or could have been a party and
indemnity could have been sought hereunder by such indemnified party, unless
such settlement includes an unconditional release of such indemnified party from
all liability on claims that are the subject matter of such proceeding.

     7. Contribution.  If the indemnification provided for in Section 6 is
        ------------                                                      
unavailable or insufficient to hold harmless an indemnified party under Section
6(a) or 6(b), then each indemnifying party shall, in lieu of indemnifying such
indemnified party, contribute to the amount paid or payable by such indemnified
party as a result of such loss, claim, damage or liability, or action in respect
thereof, (i) in such proportion as shall be appropriate to reflect the relative
benefits received by the Company and the Guarantors from the offering and sale
of the Securities, on the one hand, and a Holder with respect to the sale by
such Holder of Securities, Exchange Securities or Private Exchange Securities,
on the other, or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company and the Guarantors on the one hand and such Holder on the
other with respect to the statements or omissions that resulted in such loss,
claim, damage or liability, or action in respect thereof, as well as any other
relevant equitable considerations.  The relative benefits received by the
Company and the Guarantors on the one hand and a Holder on the other with
respect to such offering and such sale shall be deemed to be in the same
proportion as the total net proceeds from the offering of the Securities (before
deducting expenses) received by or on behalf of the Company and the Guarantors
as set forth in the table on the cover of the Offering Memorandum, on the one
hand, bear to the total proceeds received by such Holder with respect to its
sale of Securities, Exchange Securities or Private Exchange Securities, on the
other.  The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to the Company or
a Guarantor or information supplied by the Company or a Guarantor on the one
hand, or to any Holders' Information supplied by such Holder on the other, the
intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such untrue statement or omission.  The
parties hereto agree that it would not be just and equitable if contributions
pursuant to this Section 7 were to be determined by pro rata allocation or by
any other method of allocation that does not take into account the equitable
considerations referred to herein.  The amount paid or payable by an indemnified
party as a result of the loss, claim, damage or liability, or action in respect
thereof, referred to above in this Section 7 shall be deemed to include, for
purposes of this Section 7, any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending or
preparing to defend any such action or claim.  Notwithstanding the provisions of
this Section 7, an indemnifying party that is a Holder of Securities, Exchange
Securities or Private Exchange Securities shall not be required to contribute
any amount in excess of the amount by which the total price at which the
Securities, Exchange Securities or Private Exchange Securities sold by such
indemnifying party to any purchaser exceeds the amount of any damages which such
indemnifying party has otherwise paid or become liable to pay by reason of any
untrue or alleged untrue statement or 
<PAGE>
 
                                                                              15

omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

     8. Rules 144 and 144A.  The Company shall use its reasonable best efforts
        ------------------                                                      
to file the reports required to be filed by it under the Securities Act and the
Exchange Act in a timely manner and, if at any time the Company is not required
to file such reports, it will, upon the written request of any Holder of
Transfer Restricted Securities, make publicly available other information so
long as necessary to permit sales of such Holder's securities pursuant to Rules
144 and 144A.  The Company and each Guarantor covenants that it will take such
further action as any Holder of Transfer Restricted Securities may reasonably
request, all to the extent required from time to time to enable such Holder to
sell Transfer Restricted Securities without registration under the Securities
Act within the limitation of the exemptions provided by Rules 144 and 144A
(including, without limitation, the requirements of Rule 144A(d)(4)).  Upon the
written request of any Holder of Transfer Restricted Securities, the Company and
the Guarantors shall deliver to such Holder a written statement as to whether
they have complied with such requirements. Notwithstanding the foregoing,
nothing in this Section 8 shall be deemed to require the Company or a Guarantor
to register any of its securities pursuant to the Exchange Act.

     9. Underwritten Registrations.  If any of the Transfer Restricted
        --------------------------                                    
Securities covered by any Shelf Registration Statement are to be sold in an
underwritten offering, the investment banker or investment bankers and manager
or managers that will administer the offering will be selected by the Holders of
a majority in aggregate principal amount of such Transfer Restricted Securities
included in such offering, subject to the consent of the Company and the
Guarantors (which shall not be unreasonably withheld or delayed), and such
Holders shall be responsible for all underwriting commissions and discounts in
connection therewith.

          No person may participate in any underwritten registration hereunder
unless such person (i) agrees to sell such person's Transfer Restricted
Securities on the basis reasonably provided in any underwriting arrangements
approved by the persons entitled hereunder to approve such arrangements and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

     10. Miscellaneous.  (a)  Amendments and Waivers.  The provisions of this
         -------------        ----------------------                         
Agreement may not be amended, modified or supplemented, and waivers or consents
to departures from the provisions hereof may not be given, unless the Company
and the Guarantors have obtained the written consent of Holders of a majority in
aggregate principal amount of the Securities, the Exchange Securities and the
Private Exchange Securities, taken as a single class.  Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with respect
to a matter that relates exclusively to the rights of Holders whose Securities,
Exchange Securities or Private Exchange Securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect the
rights of other Holders may be given by Holders of a majority in aggregate
principal amount of the

                                                                              16

Securities, the Exchange Securities and the Private Exchange Securities being
sold by such Holders pursuant to such Registration Statement.

          (b)  Notices. All notices and other communications provided for or
               -------

telecopier or air courier guaranteeing next-day delivery:

          (i)   if to a Holder, at the most current address given by such Holder
     to the Company in accordance with the provisions of this Section 10(b),

     such Holder maintained by the Registrar under the Indenture, with a copy in
     like manner to Chase Securities Inc. and Lehman Brothers Inc.;

          (ii)  if to an Initial Purchaser, initially at its address set forth
     in the Purchase Agreement; and

          (iii) if to the Company or a Guarantor, initially at the address of
     the Company set forth in the Purchase Agreement.

          All such notices and communications shall be deemed to have been duly
given:  when delivered by hand, if personally delivered; one business day after
being delivered to a next-day air courier; five business days after being
deposited in the mail; and when receipt is acknowledged by the recipient's
telecopier machine, if sent by telecopier.

          (c)  Successors And Assigns.  This Agreement shall be binding upon the
               ----------------------                                           
Company, the Guarantors and their respective successors and assigns.

          (d)  Counterparts.  This Agreement may be executed in any number of
               ------------                                                  
counterparts (which may be delivered in original form or by telecopier) and by
the parties hereto in separate counterparts, each of which when so executed
shall be deemed to be an original and all of which taken together shall
constitute one and the same agreement.

          (e)  Definition of Terms.  For purposes of this Agreement, (i) the 
               -------------------
term "business day" means any day on which the New York Stock Exchange, Inc. is
open for trading, (ii) the term "subsidiary" has the meaning set forth in Rule
405 under the Securities Act and (iii) except where otherwise expressly
provided, the term "affiliate" has the meaning set forth in Rule 405 under the
Securities Act.

          (f)  Headings.  The headings in this Agreement are for convenience of
               --------                                                        
reference only and shall not limit or otherwise affect the meaning hereof.

          (g)  Governing Law. This Agreement shall be governed by and construed
               -------------                                                   
in accordance with the laws of the State of New York.

          (h)  Remedies.  In the event of a breach by the Company, a Guarantor 
               --------
or by any Holder of any of their obligations under this Agreement, each Holder
or the Company and the Guarantors, as the case may be, in addition to being
entitled to exercise all rights granted by law, including recovery of damages
(other than the recovery of damages for a breach by the Company or a Guarantor
of its obligations under Sections 1 or 2 hereof for which liquidated damages
have been 
<PAGE>
 
                                                                              17

paid pursuant to Section 3 hereof), will be entitled to specific performance of
its rights under this Agreement. The Company, the Guarantors and each Holder
agree that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of any of the provisions of this Agreement
and hereby further agree that, in the event of any action for specific
performance in respect of such breach, it shall waive the defense that a remedy
at law would be adequate.

          (i)  No Inconsistent Agreements.  The Company and each Guarantor
               --------------------------                                 
represents, warrants and agrees that (i) it has not entered into, shall not, on
or after the date of this Agreement, enter into any agreement that is
inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof, (ii) it has not previously
entered into any agreement which remains in effect granting any registration
rights with respect to any of its debt securities to any person and (iii)
without limiting the generality of the foregoing, without the written consent of
the Holders of a majority in aggregate principal amount of the then outstanding
Transfer Restricted Securities, it shall not grant to any person the right to
request the Company or any Guarantor to register any debt securities of the
Company or any Guarantor (or any guarantees of such debt securities) under the
Securities Act unless the rights so granted are not in conflict or inconsistent
with the provisions of this Agreement.

          (j)  No Piggyback on Registrations.  The Company, the Guarantor and
               -----------------------------                                 
their respective security holders (other than the Holders of Transfer Restricted
Securities in such capacity) shall not have the right to include any securities
of the Company in any Shelf Registration or Registered Exchange Offer other than
Transfer Restricted Securities.

          (k)  Severability. The remedies provided herein are cumulative and not
               ------------                                                     
exclusive of any remedies provided by law.  If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their reasonable best efforts to find and employ an alternative
means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction.  It is hereby stipulated and
declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of
such that may be hereafter declared invalid, illegal, void or unenforceable.

          (l)  No Foreign Registration.  Nothing in this Agreement shall be
               -----------------------                                     
construed to require the Company or any Guarantor to offer any Exchange
Securities in any non-U.S. jurisdiction where such offer would be unlawful or
require registration or qualification.  Securities are "freely transferable" for
purposes of this Agreement if they are freely transferable in the United States,
regardless of whether they may transfered within any foreign jurisdiction.

among the Company, the Guarantors and the Initial Purchasers.

          Each broker-dealer that receives Exchange Securities for its own
account pursuant to the Registered Exchange Offer must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Securities.
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.  This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Securities received in exchange for
Securities where such Securities were acquired by such broker-dealer as a result
of market-making activities or other trading activities.  The Company has agreed
that, for a period of 180 days after the Expiration Date (as defined herein), it
will make this Prospectus available to any broker-dealer for use in connection
with any such resale.  See "Plan of Distribution."

          Each broker-dealer that receives Exchange Securities for its own
account in exchange for Securities, where such Securities were acquired by such
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 such Exchange Securities.  See "Plan of Distribution."

                             PLAN OF DISTRIBUTION


          Each broker-dealer that receives Exchange Securities for its own
account pursuant to the Registered Exchange Offer must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Securities.
This Prospectus, as it may be amended or supplemented from time to time, may be
used by a broker-dealer in connection with resales of Exchange Securities
received in exchange for Securities where such Securities were acquired as a
result of market-making activities or other trading activities.  The Company has
agreed that, for a period of 180 days after the Expiration Date, it will make
this prospectus, as amended or supplemented, available to any broker-dealer for
use in connection with any such resale.  In addition, until _______________,
199_, all dealers effecting transactions in the Exchange Securities may be
required to deliver a prospectus.

          The Company will not receive any proceeds from any sale of Exchange
Securities by broker-dealers.  Exchange Securities received by broker-dealers
for their own account pursuant to the Registered 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 Exchange
Securities or a combination of such methods of resale, at market prices
prevailing at the time of resale, at prices related to such prevailing market
prices or at negotiated prices.  Any such 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 such broker-dealer or the
purchasers of any such Exchange Securities.  Any broker-dealer that resells
Exchange Securities that were received by it for its own account pursuant to the
Registered Exchange Offer and any broker or dealer that participates in a
distribution of such Exchange Securities may be deemed to be an "underwriter"
within the meaning of the Securities Act and any profit on any such resale of
Exchange Securities and any commission or concessions received by any such
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 after the Expiration Date the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal.  The Company has agreed to pay all expenses
incident to the Registered Exchange Offer (including the expenses of one counsel
for the Holders of the Securities) other than commissions or concessions of any
broker-dealers and will indemnify the Holders of the Securities (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.

the Borrower, in addition to the Revolving Credit Loans provided for by Section
2.01(a) hereof, by the issuance by the Issuing Lender of letters of credit
(collectively, "Letters of Credit") for account of the Borrower or any of its
                -----------------

                                             --------

$3,000,000 and (iii) the expiration date of any Letter of Credit extend beyond
the earlier of five Business Days prior to the Revolving Credit Commitment
Termination Date and the date twelve months following the issuance of such
Letter of Credit.  Letters of Credit issued under the Existing Credit Agreement
which are outstanding on the Amendment/Restatement Effective Date shall be
deemed to be Letters of Credit issued under this Agreement on the
Amendment/Restatement Effective Date.  The following additional provisions shall
apply to Letters of Credit:

          (a)  The Borrower shall give the Administrative Agent at least three
     Business Days' irrevocable prior notice (effective upon receipt) specifying
     the Business Day (which shall be no later than 30 days preceding the
     Revolving Credit Commitment Termination Date) each Letter of Credit is to
     be issued and the account party or parties therefor and describing in
     reasonable detail the proposed terms of such Letter of Credit (including
     the beneficiary thereof) and the nature of the transactions or obligations
     proposed to be supported thereby (including whether such Letter of Credit
     is to be a commercial letter of credit or a standby letter of credit).
     Upon receipt of any such notice, the Administrative Agent shall advise the
     Issuing Lender of the contents thereof.

          (b)  On each day during the period commencing with the issuance by the
     Issuing Lender of any Letter of Credit and until such Letter of Credit
     shall have expired or been terminated, the Revolving Credit Commitment of
     each Revolving Credit Lender shall be deemed to be utilized for all
     purposes of this Agreement in an amount equal to such Lender's Revolving
     Credit Commitment Percentage of the then undrawn face amount of such Letter
     of Credit.  Each Revolving Credit Lender (other than the Issuing Lender)
     agrees that, upon the issuance of any Letter of Credit hereunder, it shall
     automatically acquire a participation in the Issuing Lender's liability
     under such Letter of Credit in an amount equal to such Lender's Revolving
     Credit Commitment Percentage of such liability, and each Revolving Credit
     Lender (other than the Issuing Lender) thereby shall absolutely,
     unconditionally and irrevocably assume, as primary obligor and not as
     surety, and shall be unconditionally obligated to the Issuing Lender to pay
     and discharge when due, its Revolving Credit Commitment Percentage of the
     Issuing Lender's liability under such Letter of Credit.

          (c)  Upon receipt from the beneficiary of any Letter of Credit of any
     demand for payment under such Letter of Credit, the Issuing Lender shall
     promptly notify the Borrower (through the Administrative Agent) of the
     amount to be paid by the Issuing Lender as a result of 
<PAGE>
 
                                                                              23

     such demand and the date on which payment is to be made by the Issuing
     Lender to such beneficiary in respect of such demand. Notwithstanding the
     identity of the account party of any Letter of Credit, the Borrower hereby
     unconditionally agrees to pay and reimburse the Administrative Agent for
     account of the Issuing Lender for the amount of each demand for payment
     under such Letter of Credit that is in substantial compliance with the
     provisions of such Letter of Credit at or prior to the date on which
     payment is to be made by the Issuing Lender to the beneficiary thereunder,
     without presentment, demand, protest or other formalities of any kind.

          (d)  Forthwith upon its receipt of a notice referred to in paragraph
     (c) of this Section 2.03, the Borrower shall advise the Administrative
     Agent whether or not the Borrower intends to borrow hereunder to finance
     its obligation to reimburse the Issuing Lender for the amount of the
     related demand for payment and, if it does, submit a notice of such
     borrowing as provided in Section 4.05 hereof.

          (e)  Each Revolving Credit Lender (other than the Issuing Lender)
     shall pay to the Administrative Agent for account of the Issuing Lender at
     the Principal Office in Dollars and in immediately available funds, the
     amount of such Lender's Revolving Credit Commitment Percentage of any
     payment under a Letter of Credit upon notice by the Issuing Lender (through
     the Administrative Agent) to such Revolving Credit Lender requesting such
     payment and specifying such amount.  Each such Revolving Credit Lender's
     obligation to make such payment to the Administrative Agent for account of
     the Issuing Lender under this paragraph (e), and the Issuing Lender's right
     to receive the same, shall be absolute and unconditional and shall not be
     affected by any circumstance whatsoever, including, without limitation, the
     failure of any other Revolving Credit Lender to make its payment under this
     paragraph (e), the financial condition of the Borrower (or any other
     account party), the existence of any Default or the termination of the
     Commitments.  Each such payment to the Issuing Lender shall be made without
     any offset, abatement, withholding or reduction whatsoever.  If any
     Revolving Credit Lender shall default in its obligation to make any such
     payment to the Administrative Agent for account of the Issuing Lender, for
     so long as such default shall continue the Administrative Agent may at the
     request of the Issuing Lender withhold from any payments received by the
     Administrative Agent under this Agreement or any Note for account of such
     Revolving Credit Lender the amount so in default and, to the extent so
     withheld, pay the same to the Issuing Lender in satisfaction of such
     defaulted obligation.

          (f)  Upon the making of each payment by a Revolving Credit Lender to
     the Issuing Lender pursuant to paragraph (e) above in respect of any Letter
     of Credit, such Lender shall, automatically and without any further action
     on the part of the Administrative Agent, the Issuing Lender or such Lender,
     acquire (i) a participation in an amount equal to such payment in the
     Reimbursement Obligation owing to the Issuing Lender by the Borrower
     hereunder and under the Letter of Credit Documents relating to such Letter
     of Credit and (ii) a participation in a percentage equal to such Lender's
     Revolving Credit Commitment Percentage in any interest or other amounts
     payable by the Borrower hereunder and under such Letter of Credit Documents
     in respect of such Reimbursement Obligation (other than the commissions,
     charges, costs and expenses payable to the Issuing Lender pursuant to
     paragraph (g) of this Section 2.03).  Upon receipt by the Issuing Lender
     from or for account of the Borrower of any payment in respect of any
     Reimbursement Obligation or any such interest or other amount (including by
     way of setoff or application of proceeds of any collateral security) the
     Issuing Lender shall promptly pay to the Administrative Agent for account
     of each Revolving Credit Lender entitled thereto, such Revolving Credit
     Lender's Revolving Credit Commitment Percentage of such payment, each such
     payment by the Issuing Lender to be made in the same money and funds in
     which received 
<PAGE>
 
                                                                              24

     by the Issuing Lender. In the event any payment received by the Issuing
     Lender and so paid to the Revolving Credit Lenders hereunder is rescinded
     or must otherwise be returned by the Issuing Lender, each Revolving Credit
     Lender shall, upon the request of the Issuing Lender (through the
     Administrative Agent), repay to the Issuing Lender (through the
     Administrative Agent) the amount of such payment paid to such Lender, with
     interest at the rate specified in paragraph (j) of this Section 2.03.

          (g)  The Borrower shall pay to the Administrative Agent for account of
     each Revolving Credit Lender (ratably in accordance with their respective
     Revolving Credit Commitment Percentages) a letter of credit fee on the
     daily average undrawn face amount of such Letter of Credit at a rate per
     annum equal to the Applicable Margin for Revolving Credit Loans that are
     Eurodollar Loans for the period from and including the date of issuance of
     such Letter of Credit (i) in the case of a Letter of Credit that expires in
     accordance with its terms, to and including such expiration date and (ii)
     in the case of a Letter of Credit that is drawn in full or is otherwise
     terminated other than on the stated expiration date of such Letter of
     Credit, to but excluding the date such Letter of Credit is drawn in full or
     is terminated (such fee to be non-refundable, to be paid in arrears on each
     Quarterly Date and on the Revolving Credit Commitment Termination Date and
     to be calculated for any day after giving effect to any payments made under
     such Letter of Credit on such day).  In addition, the Borrower shall pay to
     the Administrative Agent for account of the Issuing Lender a fronting fee
     in respect of each Letter of Credit in an amount equal to 1/4 of 1% per
     annum of the daily average undrawn face amount of such Letter of Credit for
     the period from and including the date of issuance of such Letter of Credit
     (i) in the case of a Letter of Credit that expires in accordance with its
     terms, to and including such expiration date and (ii) in the case of a
     Letter of Credit that is drawn in full or is otherwise terminated other
     than on the stated expiration date of such Letter of Credit, to but
     excluding the date such Letter of Credit is drawn in full or is terminated
     (such fee to be non-refundable, to be paid in arrears on each Quarterly
     Date and on the Revolving Credit Commitment Termination Date and to be
     calculated for any day after giving effect to any payments made under such
     Letter of Credit on such day) plus all commissions, charges, costs and
     expenses in the amounts customarily charged by the Issuing Lender from time
     to time in like circumstances with respect to the issuance of each Letter
     of Credit and drawings and other transactions relating thereto.

          (h)  Promptly following the end of each calendar quarter, the Issuing
     Lender shall deliver (through the Administrative Agent) to each Revolving
     Credit Lender and the Borrower a notice describing the aggregate amount of
     all Letters of Credit outstanding at the end of such quarter.  Upon the
     request of any Revolving Credit Lender from time to time, the Issuing
     Lender shall deliver any other information reasonably requested by such
     Lender with respect to each Letter of Credit then outstanding.

          (i)  The issuance by the Issuing Lender of each Letter of Credit
     shall, in addition to the conditions precedent set forth in Section 7
     hereof, be subject to the conditions precedent that (i) such Letter of
     Credit shall be in such form, contain such terms and support such
     transactions as shall be satisfactory to the Issuing Lender consistent with
     its then current practices and procedures with respect to letters of credit
     of the same type and (ii) the Borrower shall have executed and delivered
     such applications, agreements and other instruments relating to such Letter
     of Credit as the Issuing Lender shall have reasonably requested consistent
     with its then current practices and procedures with respect to letters of
     credit of the same type, provided that in the event of any conflict between
                              --------                                          
     any such application, agreement or other instrument and the provisions of
     this Agreement or any Security Document, the provisions of this Agreement
     and the Security Documents shall control.

          (j)  To the extent that any Lender shall fail to pay any amount
     required to be paid pursuant to paragraph (e) or (f) of this Section 2.03
     on the due date therefor, such Lender shall pay interest to the Issuing
     Lender (through the Administrative Agent) on such amount from and including
     such due date to but excluding the date such payment is made at a rate per
     annum equal to the Federal Funds Rate, provided that if such Lender shall
                                            --------                          
     fail to make such payment to the Issuing Lender within three Business Days
     of such due date, then, retroactively to the due date, such Lender shall be
     obligated to pay interest on such amount at the Post-Default Rate.

          (k)  The issuance by the Issuing Lender of any modification or
     supplement to any Letter of Credit hereunder shall be subject to the same
     conditions applicable under this Section 2.03 to the issuance of new
     Letters of Credit, and no such modification or supplement shall be issued
     hereunder unless either (i) the respective Letter of Credit affected
     thereby would have complied with such conditions had it originally been
     issued hereunder in such modified or supplemented form or (ii) each
     Revolving Credit Lender shall have consented thereto.

The Borrower hereby indemnifies and holds harmless each Revolving Credit Lender
and the Administrative Agent from and against any and all claims and damages,
losses, liabilities, costs or expenses that such Lender or the Administrative
Agent may incur (or that may be claimed against such Lender or the
Administrative Agent by any Person whatsoever) by reason of or in connection
with the execution and delivery or transfer of or payment or refusal to pay by
the Issuing Lender under any Letter of Credit; provided that the Borrower shall
                                               --------                        
not be required to indemnify any Lender or the Administrative Agent for any
claims, damages, losses, liabilities, costs or expenses to the extent, but only
to the extent, caused by (x) the willful misconduct or gross negligence of the
Issuing Lender in determining whether a request presented under any Letter of
Credit complied with the terms of such Letter of Credit or (y) in the case of
the Issuing Lender, such Lender's failure to pay under any Letter of Credit
after the presentation to it of a request strictly complying with the terms and
conditions of such Letter of Credit unless it is prohibited from doing so by an
injunction or other order of any court.  Nothing in this Section 2.03 is
intended to limit the other obligations of the Borrower, any Lender or the
Administrative Agent under this Agreement.

          2.04  Changes of Commitments.  The Borrower shall have the right at

any time or from time to time (i)  so long as no Revolving Credit Loans or
Letter of Credit Liabilities are outstanding, to terminate the Revolving Credit
Commitments and (ii) to reduce the aggregate unused amount of the Revolving
Credit Commitments (for which purpose use of the Revolving Credit Commitments
shall be deemed to include the aggregate amount of Letter of Credit
Liabilities); provided that (x) the Borrower shall give notice of each such
              --------                                                     
termination or reduction as provided in Section 4.05 hereof and (y) each partial
reduction shall be in an aggregate amount at least equal to $5,000,000 (or a
larger multiple of $1,000,000).  The Commitments once terminated or reduced may
not be reinstated.

          2.05  Commitment Fee.  The Borrower shall pay to the Administrative
                --------------                                               
Agent for the account of each Lender a commitment fee on the daily average
unused amount of such Lender's Revolving Credit Commitment (for which purpose
the aggregate amount of any Letter of Credit Liabilities shall be deemed to be a
pro rata (based on the Revolving Credit Commitments) use of each Lender's

Amendment/Restatement Effective Date to but not including the earlier of the
date such Revolving Credit Commitment is terminated and the Revolving Credit
Commitment Termination Date, at a rate per annum equal to (a) 1/2 of 1%, at any
time when the Applicable Margin in respect of Eurodollar Loans that are
Revolving Credit Loans is 1.75% or higher or (b) 3/8 of 1%, at any other time.
Accrued commitment fees shall be payable on each Quarterly Date and on the
earlier of the date the relevant Commitments are terminated and the Revolving
Credit Commitment Termination Date.

shall be made and maintained at such Lender's Applicable Lending Office for
Loans of such Type.

          2.07  Several Obligations; Remedies Independent.  The failure of any
                -----------------------------------------                     
Lender to make any Loan to be made by it on the date specified therefor shall
not relieve any other Lender of its obligation to make its Loan on such date,
but neither any Lender nor the Administrative Agent shall be responsible for the
failure of any other Lender to make a Loan to be made by such other Lender, and
(except as otherwise provided in Section 4.06 hereof) no Lender shall have any
obligation to the Administrative Agent or any other Lender for the failure by
such Lender to make any Loan required to be made by such Lender.  The amounts
payable by the Borrower at any time hereunder and under any Notes to each Lender
shall be a separate and independent debt and each Lender shall be entitled to
protect and enforce its rights arising out of this Agreement and any Notes, and
it shall not be necessary for any other Lender or the Administrative Agent to
consent to, or be joined as an additional party in, any proceedings for such
purposes.

          2.08  Evidence of Loans; Notes.
                ------------------------ 

          (a)  The Borrower agrees that, upon the request to the Administrative
Agent by any Revolving Credit Lender made on or prior to the

Credit Loans, the Borrower will execute and deliver to such Lender a single

          (b)  The Borrower agrees that, upon the request to the Administrative
Agent by any Tranche A Lender made on or prior to the Amendment/Restatement

          (c)  The Borrower agrees that, upon the request to the Administrative
Agent by any Tranche B Lender made on or prior to the Amendment/Restatement

          (d)  Each Lender shall maintain in accordance with its usual practice
an account or accounts evidencing indebtedness of the Borrower to such Lender

amount of each Loan of each Class made hereunder, the Type thereof, and, in the
case of Eurodollar Loans, each Interest Period applicable thereto, (ii) the
amount of any principal or interest due and payable or to become due and payable
from the Borrower to each Lender hereunder and (iii) both the amount of any

existence and amounts of the obligations of the Borrower therein recorded;
provided, however, that the failure of any Lender or the Administrative Agent to

maintain the Register or any such account, or any error therein, shall not in
any manner affect the obligation of the Borrower to repay (with applicable
interest) any Loan of any Class made to the Borrower by such Lender in
accordance with the terms of this Agreement.

          (e)  No Lender shall be entitled to have its Notes substituted or
exchanged for any reason, or subdivided for promissory notes of lesser
denominations, except in connection with a permitted assignment of all or any
portion of such Lender's relevant Commitment, Loans and Notes pursuant to
Section 12.06 hereof and except as provided in clause (f) below (and, if
requested by any Lender, the Borrower agrees to so exchange any Note).

          (f)  Notwithstanding the foregoing, any Lender that is not a U.S.
Person and is not a "bank" within the meaning of Section 881(c)(3)(A) of the
Code and that has made a written request to the Borrower (through the
Administrative Agent) for a promissory note and any direct or indirect assignee
of such Lender (such Lender and any such assignee, a "Qualified Foreign Lender")
                                                      ------------------------  
shall receive a promissory note in registered form to evidence its Loans (i.e.
containing the optional registered note language as indicated in Exhibits A-1,
A-2 or A-3 hereto, as the case may be) (herein, a "Registered Note"), dated the
                                                   ---------------             
Amendment/Restatement Effective Date, payable to such Lender or registered
assigns and otherwise duly completed.  Once issued, Registered Notes (i) shall
be deemed to and shall be "Notes" and "Tranche A Term Notes," "Tranche B Term
Notes" or "Revolving Credit Notes," as the case may be, for all purposes under
this Agreement, the Security Documents and the other Loan Documents, (ii) may
not be exchanged for Revolving Credit Notes, Tranche A Term Notes or Tranche B
Term Notes, notwithstanding anything to the contrary in this Agreement, and
(iii) shall at all times thereafter be Registered Notes, including, without
limitation, following any transfer or assignment thereof.

          (g)  Each Lender that is a "Lender" under the Existing Credit
Agreement shall return to the Borrower for cancellation any notes held by it
thereunder promptly after the Amendment/Restatement Effective Date.

          2.09  Optional Prepayments and Conversions or Continuations of Loans.
                --------------------------------------------------------------  
Subject to Section 4.04 hereof, the Borrower shall have the right to prepay
Loans, or to Convert Loans of one Type into Loans of another Type or Continue
Loans of one Type as Loans of the same Type, at any time or from time to time,
provided that:  (a) the Borrower shall give the Administrative Agent notice of
- --------                                                                      
each such prepayment, Conversion or Continuation as provided in Section 4.05
hereof (and, upon the date specified in any such notice of prepayment, the
amount to be prepaid shall become due and payable hereunder); (b) Eurodollar
Loans may be prepaid or Converted only on the last day of an Interest Period for
such Loans; (c) prepayments of the Term Loans shall be applied ratably to the
Tranche A Term Loans and the Tranche B Term Loans and, in the case of each such
Class, to the installments of the Term Loans in direct order of their scheduled
maturities; and (d) any Conversion or Continuation of Eurodollar Loans shall be
subject to the provisions of Section 2.01(d) hereof.  Notwithstanding the
foregoing, and without limiting the rights and remedies of the Lenders under
Section 10 hereof, in the event that any Event of Default shall have occurred
and be continuing, the Administrative Agent may (and at the request of the
Majority Lenders shall) suspend the right of the Borrower to Convert any Loan
into a Eurodollar Loan, or to Continue any Loan as a Eurodollar Loan, in which
event all Loans shall be Converted (on the last day(s) of the respective
Interest Periods therefor) or Continued, as the case may be, as Base Rate Loans.

determined not to repair or replace the Property affected by such Casualty
Event), the Borrower shall prepay the Term Loans, and the Term Loan Commitments
shall be automatically reduced in an aggregate amount, if any, equal to 100% of
the Net Available Proceeds of such Casualty Event not theretofore applied to the
repair or replacement of such Property, such prepayment and reduction to be
effected in each case in the manner and to the extent specified in paragraph (f)
of this Section 2.10.  Nothing in this paragraph (a) shall be deemed to limit
any obligation of the Borrower or any of its Subsidiaries pursuant to any of the
Security Documents to remit to a collateral or similar account (including,
without limitation, the Collateral Account) maintained by the Administrative
Agent pursuant to any of the Security Documents the proceeds of insurance,
condemnation award or other compensation received in respect of any Casualty

Section 9.01(b) hereof (or, if such consolidated and consolidating financial
statements are not received by the last day on which they are required to be
delivered, not later than 30 days after the last day on which such financial

of all prior Dispositions as to which a prepayment has not yet been made under
this Section 2.10(e), but excluding the amount of any Reinvestable Proceeds (as

so to use such portion, such portion shall cease to be Reinvestable Proceeds on
such 270th day and shall be deemed to be Net Available Proceeds of a Disposition
that has occurred on such day and (ii) if after giving effect to such
determination the then aggregate amount of Reinvestable Proceeds that have not
been used to so repair or replace Properties shall be in excess of $10,000,000,
such aggregate amount shall be promptly deposited in a cash collateral account
established at Chase to be held as collateral in favor of the Administrative
Agent for the benefit of the Lenders on terms reasonably satisfactory to the
Administrative Agent and shall remain on deposit in such cash collateral account
until such aggregate amount (or, with respect to any portion thereof, such

          (a)  The Borrower hereby promises to pay to the Administrative Agent
for account of each Lender the entire outstanding principal amount of such
Lender's Revolving Credit Loans, and each Revolving Credit Loan shall mature, on
the Revolving Credit Commitment Termination Date.  In addition, if at any time
the aggregate principal amount of the Revolving Credit Loans, together with the
aggregate amount of all Letter of Credit Liabilities, shall exceed the Revolving
Credit Commitments, the Borrower shall, first, pay Revolving Credit Loans and,
second, provide cover for Letter of Credit Liabilities, in an aggregate amount
equal to such excess.  In the event that the Borrower shall be required pursuant
to this Section 3.01(a) to provide cover for Letter of Credit Liabilities, the
Borrower shall effect the same by paying to the Administrative Agent immediately
available funds in an amount equal to the required amount, which funds shall be
retained by the Administrative Agent in the Collateral Account (as provided
therein as collateral security in the first instance for the Letter of Credit
Liabilities) until such time as the Letters of Credit shall have been terminated
and all of the Letter of Credit Liabilities paid in full.

Administrative Agent for account of each Lender interest on the unpaid principal
amount of each Loan made by such Lender for the period from and including the
date of such Loan to but excluding the date such Loan shall be paid in full, at
the following rates per annum:

          (a)  during such periods as such Loan is a Base Rate Loan, the Base
     Rate (as in effect from time to time) plus the Applicable Margin and

          (b)  during such periods as such Loan is a Eurodollar Loan, for each
     Interest Period relating thereto, the Eurodollar Rate for such Loan for
     such Interest Period plus the Applicable Margin.
                          ----                       

Notwithstanding the foregoing, the Borrower hereby promises to pay to the
Administrative Agent for account of each Lender interest at the applicable Post-
Default Rate on any principal of any Loan made by such Lender, on any
Reimbursement Obligation held by such Lender and on any other amount payable by
the Borrower hereunder or under any Notes held by such Lender to or for account
of such Lender, that shall not be paid in full when due (whether at stated
maturity, by acceleration, by mandatory prepayment or otherwise), for the period
from and including the due date thereof to but excluding the date the same is
paid in full.  Accrued interest on each Loan shall be payable (i) in the case of
a Base Rate Loan, quarterly on the Quarterly Dates, (ii) in the case of a
Eurodollar Loan, on the last day of each Interest Period therefor and, if such
Interest Period is longer than three months, at three-month intervals following
the first day of such Interest Period, and (iii) in the case of any Eurodollar
Loan, upon the payment or prepayment thereof or the Conversion of such Loan to a
Loan of another Type (but only on the principal amount so paid, prepaid or
Converted), except that interest payable at the Post-Default Rate shall be
payable from time to time on demand.  Promptly after the determination of any
interest rate provided for herein or any change therein, the Administrative
Agent shall give notice thereof to the Lenders to which such interest is payable
and to the Borrower.

Lenders for application in such ratable manner as it, subject to Section 4.02
hereof, may reasonably determine to be appropriate).

extended to the next succeeding Business Day, and interest shall be payable for
any principal so extended for the period of such extension.

Administrative Agent of (in the case of a Lender) the proceeds of a Loan to be
made by such Lender hereunder or (in the case of the Borrower) a payment to the
Administrative Agent for account of one or more of the Lenders hereunder (such
payment being herein called the "Required Payment"), which notice shall be

Payment to the Administrative Agent, the Administrative Agent may assume that
the Required Payment has been made and may, in reliance upon such assumption
(but shall not be required to), make the amount thereof available to the
intended recipient(s) on such date; and, if the Payor has not in fact made the
Required Payment to the Administrative Agent, the recipient(s) of such payment
shall, on demand, repay to the Administrative Agent the amount so made available
together with interest thereon in respect of each day during the period
commencing on the date (the "Advance Date") such amount was so made available by

the Administrative Agent until the date the Administrative Agent recovers such
amount at a rate per annum equal to the Federal Funds Rate for such day and, if
such recipient(s) shall fail promptly to make such payment, the Administrative
Agent shall be entitled to recover such amount, on demand, from the Payor,
together with interest as aforesaid, provided that if neither the recipient(s)

nor the Payor shall return the Required Payment to the Administrative Agent
within three Business Days of the Advance Date, then, retroactively to the
Advance Date, the Payor and the recipient(s) shall each be obligated to pay
interest on the Required Payment as follows:

               (i)   if the Required Payment shall represent a payment to be
     made by the Borrower to the Lenders, the Borrower and the recipient(s)
     shall each be obligated retroactively to the Advance Date to pay interest
     in respect of the Required Payment at the Post-Default Rate (without
     duplication of the obligation of the Borrower under Section 3.02 hereof to
     pay interest on the Required Payment at the Post-Default Rate), it being
     understood that the return by the recipient(s) of the Required Payment to
     the Administrative Agent shall not limit such obligation of the Borrower
     under said Section 3.02 to pay interest at the Post-Default Rate in respect
     of the Required Payment and

               (ii)  if the Required Payment shall represent proceeds of a Loan
     to be made by the Lenders to the Borrower, the Payor and the Borrower shall
     each be obligated retroactively to the Advance Date to pay interest in
     respect of the Required Payment pursuant to whichever of the rates
     specified in Section 3.02 hereof is applicable to the Type of such Loan, it
     being understood that the return by the Borrower of the Required Payment to
     the Administrative Agent shall not limit any claim the Borrower may have
     against the Payor in respect of such Required Payment.

          4.07  Sharing of Payments, Etc.
                -------------------------

          (a)  Each Obligor agrees that, in addition to (and without limitation
of) any right of set-off, banker's lien or counterclaim a Lender may otherwise
have, each Lender shall be entitled, at its option (to the fullest extent
permitted by law), to set off and apply any deposit (general or special, time or
demand, provisional or final), or other indebtedness, held by it for the credit
or account of such Obligor at any of its offices, in Dollars or in any other
currency, against any principal of or interest on any of such Lender's Loans,
Reimbursement Obligations or any other amount payable to such Lender hereunder,
that is not paid when due (regardless of whether such deposit or other
indebtedness are then due to such Obligor), in which case it shall promptly
notify such Obligor and the Administrative Agent thereof, provided that such
                                                          --------          
Lender's failure to give such notice shall not affect the validity thereof.

          (b)  If any Lender shall obtain from any Obligor payment of any
principal of or interest on any Loan of any Class or Letter of Credit Liability
owing to it or payment of any other amount under 
<PAGE>
 
                                                                              35

this Agreement or any other Loan Document through the exercise of any right of
set-off, banker's lien or counterclaim or similar right or otherwise (other than
from the Administrative Agent as provided herein), and, as a result of such
payment, such Lender shall have received a greater percentage of the principal
of or interest on the Loans of such Class or Letter of Credit Liabilities or
such other amounts then due hereunder or thereunder by such Obligor to such
Lender than the percentage received by any other Lender, it shall promptly
purchase from such other Lenders participations in (or, if and to the extent
specified by such Lender, direct interests in) the Loans of such Class or Letter
of Credit Liabilities or such other amounts, respectively, owing to such other
Lenders (or in interest due thereon, as the case may be) in such amounts, and
make such other adjustments from time to time as shall be equitable, to the end
that all the Lenders shall share the benefit of such excess payment (net of any
expenses that may be incurred by such Lender in obtaining or preserving such
excess payment) pro rata in accordance with the unpaid principal of and/or
                --- ----
interest on the Loans of such Class or Letter of Credit Liabilities or such
other amounts, respectively, owing to each of the Lenders. To such end all the
Lenders shall make appropriate adjustments among themselves (by the resale of
participations sold or otherwise) if such payment is rescinded or must otherwise
be restored.

          (c)  Each Obligor agrees that any Lender so purchasing such a
participation (or direct interest) may exercise all rights of set-off, banker's
lien, counterclaim or similar rights with respect to such participation as fully
as if such Lender were a direct holder of Loans or other amounts (as the case
may be) owing to such Lender in the amount of such participation.

          (d)  Nothing contained herein shall require any Lender to exercise any
such right or shall affect the right of any Lender to exercise, and retain the
benefits of exercising, any such right with respect to any other indebtedness or
obligation of any Obligor.  If, under any applicable bankruptcy, insolvency or
other similar law, any Lender receives a secured claim in lieu of a set-off to
which this Section 4.07 applies, such Lender shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Lenders entitled under this Section 4.07 to share in the
benefits of any recovery on such secured claim.

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

          5.01  Additional Costs.
                ---------------- 

          (a)  The Borrower shall pay directly to each Lender from time to time
such amounts as such Lender may determine to be necessary to compensate such
Lender for any costs that such Lender determines are attributable to its making
or maintaining of any Eurodollar Loans or its obligation to make any Eurodollar
Loans hereunder, or any reduction in any amount receivable by such Lender
hereunder in respect of any of such Loans or such obligation (such increases in
costs and reductions in amounts receivable being herein called "Additional
                                                                ----------
Costs"), resulting from any Regulatory Change that:
- -----

               (i)   shall subject any Lender (or its Applicable Lending Office
     for any of such Loans) to any tax, duty or other charge in respect of such
     Loans or its Notes or changes the basis of taxation of any amounts payable
     to such Lender under this Agreement or its Notes in respect of any of such
     Loans (excluding changes in the rate of tax on the overall net income of
     such Lender or of such Applicable Lending Office by the jurisdiction in
     which such Lender has its principal office or such Applicable Lending
     Office); or

               (ii)  imposes or modifies any reserve, special deposit or
     similar requirements (other than the Reserve Requirement utilized in the
     determination of the Eurodollar Rate for such Loan) relating to any
     extensions of credit or other assets of, or any deposits with or other

                                                                              36

     liabilities of, such Lender (including, without limitation, any of such
     Loans or any deposits referred to in the definition of "Eurodollar Base
     Rate" in Section 1.01 hereof), or any commitment of such Lender (including,
     without limitation, the Commitments of such Lender hereunder); or

               (iii)    imposes any other condition affecting this Agreement or
     its Notes (or any of such extensions of credit or liabilities) or its
     Commitments.

If any Lender requests compensation from the Borrower under this Section
5.01(a), the Borrower may, by notice to such Lender (with a copy to the
Administrative Agent), suspend the obligation of such Lender thereafter to make
or Continue Eurodollar Loans, or to Convert Base Rate Loans into Eurodollar
Loans, until the Regulatory Change giving rise to such request ceases to be in
effect (in which case the provisions of Section 5.04 hereof shall be
applicable), provided that such suspension shall not affect the right of such
             --------                                                        
Lender to receive the compensation so requested.

          (b)  Without limiting the effect of the foregoing provisions of this
Section 5.01 (but without duplication), the Borrower shall pay directly to each
Lender from time to time on request such amounts as such Lender may determine to
be necessary to compensate such Lender (or, without duplication, the bank
holding company of which such Lender is a Subsidiary) for any costs that it
determines are attributable to the maintenance by such Lender (or any Applicable
Lending Office or such bank holding company), pursuant to any law or regulation
or any interpretation, directive or request (whether or not having the force of
law and whether or not failure to comply therewith would be unlawful) of any
court or governmental or monetary authority (i) following any Regulatory Change
or (ii) implementing any risk-based capital guideline or other requirement
(whether or not having the force of law and whether or not the failure to comply
therewith would be unlawful) hereafter issued by any government or governmental
or supervisory authority implementing at the national level the Basle Accord, of
capital in respect of its Commitments or Loans (such compensation to include,
without limitation, an amount equal to any reduction of the rate of return on
assets or equity of such Lender (or any Applicable Lending Office or such bank
holding company) to a level below that which such Lender (or any Applicable
Lending Office or such bank holding company) could have achieved but for such
law, regulation, interpretation, directive or request).

          (c)  Each Lender shall notify the Borrower of any event occurring
after the date hereof entitling such Lender to compensation under paragraph (a)
or (b) of this Section 5.01 as promptly as practicable, but in any event within
45 days, after such Lender obtains actual knowledge thereof; provided that (i)
                                                             --------         
if any Lender fails to give such notice within 45 days after it obtains actual
knowledge of such an event, such Lender shall, with respect to compensation
payable pursuant to this Section 5.01 in respect of any costs resulting from
such event, only be entitled to payment under this Section 5.01 for costs
incurred from and after the date 45 days prior to the date that such Lender does
give such notice and (ii) each Lender will designate a different Applicable
Lending Office for the Loans of such Lender affected by such event if such
designation will avoid the need for, or reduce the amount of, such compensation
and will not, in the sole opinion of such Lender, be disadvantageous to such
Lender, except that such Lender shall have no obligation to designate an
Applicable Lending Office located in the United States of America.  Each Lender
will furnish to the Borrower a certificate setting forth the basis and amount of
each request by such Lender for compensation under paragraph (a) or (b) of this
Section 5.01.  Determinations and allocations by any Lender for purposes of this
Section 5.01 of the effect of any Regulatory Change pursuant to paragraph (a) of
this Section 5.01, or of the effect of capital maintained pursuant to paragraph
(b) of this Section 5.01, on its costs or rate of return of maintaining Loans or
its obligation to make Loans, or on amounts receivable by it in respect of
Loans, and of the amounts required to compensate such Lender under this Section
5.01, shall be conclusive, provided that such determinations and allocations are
                           --------

          5.02  Limitation on Types of Loans.  Anything herein to the contrary
                ----------------------------                                  
notwithstanding, if, on or prior to the determination of any Eurodollar Base
Rate for any Interest Period:

          (a)  the Administrative Agent determines, which determination shall be
     conclusive, that quotations of interest rates for the relevant deposits
     referred to in the definition of "Eurodollar Base Rate" in Section 1.01
     hereof are not being provided in the relevant amounts or for the relevant
     maturities for purposes of determining rates of interest for Eurodollar
     Loans as provided herein; or

          (b)  if the related Loans are Revolving Credit Loans, the Majority
     Revolving Credit Lenders or, if the related Loans are Term Loans, the
     Majority Term Lenders determine, which determination shall be conclusive,
     and notify the Administrative Agent that the relevant rates of interest
     referred to in the definition of "Eurodollar Base Rate" in Section 1.01
     hereof upon the basis of which the rate of interest for Eurodollar Loans
     for such Interest Period is to be determined are not likely adequately to
     cover the cost to such Lenders of making or maintaining Eurodollar Loans
     for such Interest Period;

then the Administrative Agent shall give the Borrower and each Lender prompt
notice thereof and, so long as such condition remains in effect, the Lenders
shall be under no obligation to make additional Eurodollar Loans, to Continue
Eurodollar Loans or to Convert Base Rate Loans into Eurodollar Loans, and the
Borrower shall, on the last day(s) of the then current Interest Period(s) for
the outstanding Eurodollar Loans, either prepay such Loans or Convert such Loans
into Base Rate Loans in accordance with Section 2.09 hereof.

          5.03  Illegality.  Notwithstanding any other provision of this
                ----------                                              
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to honor its obligation to make or maintain Eurodollar
Loans hereunder (and, in the sole opinion of such Lender, the designation of a
different Applicable Lending Office would either not avoid such unlawfulness or
would be disadvantageous to such Lender), then such Lender shall promptly notify
the Borrower thereof (with a copy to the Administrative Agent) and such Lender's
obligation to make or Continue, or to Convert Loans of any other Type into,
Eurodollar Loans shall be suspended until such time as such Lender may again
make and maintain Eurodollar Loans (in which case the provisions of Section 5.04
hereof shall be applicable).

          5.04  Treatment of Affected Loans.  If the obligation of any Lender to
                ---------------------------                                     
make Eurodollar Loans or to Continue, or to Convert Base Rate Loans into,
Eurodollar Loans shall be suspended pursuant to Section 5.01 or 5.03 hereof,
such Lender's Eurodollar Loans shall be automatically Converted into Base Rate
Loans on the last day(s) of the then current Interest Period(s) for Eurodollar
Loans (or, in the case of a Conversion resulting from a circumstance described
in Section 5.03 hereof, on such earlier date as such Lender may specify to the
Borrower with a copy to the Administrative Agent) and, unless and until such
Lender gives notice as provided below that the circumstances specified in
Section 5.01 or 5.03 hereof that gave rise to such Conversion no longer exist:

          (a)  to the extent that such Lender's Eurodollar Loans have been so
     Converted, all payments and prepayments of principal that would otherwise
     be applied to such Lender's Eurodollar Loans shall be applied instead to
     its Base Rate Loans; and

          (b)  all Loans that would otherwise be made or Continued by such
     Lender as Eurodollar Loans shall be made or Continued instead as Base Rate
     Loans, and all Base Rate Loans of such 
<PAGE>
 
                                                                              38

     Lender that would otherwise be Converted into Eurodollar Loans shall remain
     as Base Rate Loans.

If such Lender gives notice to the Borrower with a copy to the Administrative
Agent that the circumstances specified in Section 5.01 or 5.03 hereof that gave
rise to the Conversion of such Lender's Eurodollar Loans pursuant to this
Section 5.04 no longer exist (which such Lender agrees to do promptly upon such
circumstances ceasing to exist) at a time when Eurodollar Loans of the same
Class made by other Lenders are outstanding, such Lender's Base Rate Loans of
such Class shall be automatically Converted, on the first day(s) of the next
succeeding Interest Period(s) for such outstanding Eurodollar Loans, to the
extent necessary so that, after giving effect thereto, all Base Rate and
Eurodollar Loans of such Class are allocated among the Lenders ratably (as to
principal amounts, Types and Interest Periods) in accordance with their
respective Commitments of such Class.

          5.05  Compensation.  The Borrower shall pay to the Administrative
                ------------                                               
Agent for account of each Lender, upon the request of such Lender through the
Administrative Agent, such amount or amounts as shall be sufficient (in the
reasonable opinion of such Lender) to compensate it for any loss, cost or
expense that such Lender determines is attributable to:

          (a)  any payment, mandatory or optional prepayment or Conversion of a
     Eurodollar Loan made by such Lender for any reason (including, without
     limitation, the acceleration of the Loans pursuant to Section 10 hereof) on
     a date other than the last day of the Interest Period for such Loan; or

          (b)  any failure by the Borrower for any reason (including, without
     limitation, the failure of any of the conditions precedent specified in
     Section 7 hereof to be satisfied) to borrow a Eurodollar Loan from such
     Lender on the date for such borrowing specified in the relevant notice of
     borrowing given pursuant to Section 2.02 hereof.

Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (i) the amount of interest
that otherwise would have accrued on the principal amount so paid, prepaid,
Converted or not borrowed for the period from the date of such payment,
prepayment, Conversion or failure to borrow to the last day of the then current
Interest Period for such Loan (or, in the case of a failure to borrow, the
Interest Period for such Loan that would have commenced on the date specified
for such borrowing) at the applicable rate of interest for such Loan provided
for herein over (ii) the amount of interest that otherwise would have accrued on
such principal amount at a rate per annum equal to the interest component of the
amount such Lender would have bid in the London interbank market for Dollar
deposits of leading banks in amounts comparable to such principal amount and
with maturities comparable to such period (as reasonably determined by such
Lender).

          5.06  Additional Costs in Respect of Letters of Credit.  Without
                ------------------------------------------------          
limiting the obligations of the Borrower under Section 5.01 hereof (but without
duplication), if as a result of any Regulatory Change or any risk-based capital
guideline or other requirement hereafter issued by any government or
governmental or supervisory authority implementing at the national level the
Basle Accord there shall be imposed, modified or deemed applicable any tax,
reserve, special deposit, capital adequacy or similar requirement against or
with respect to or measured by reference to Letters of Credit issued or to be
issued hereunder and the result shall be to increase the cost to any Lender or
Lenders of issuing (or purchasing participations in) or maintaining its
obligation hereunder to issue (or purchase participations in) any Letter of
Credit hereunder or reduce any amount receivable by any Lender hereunder in
respect of any Letter of Credit (which increases in cost, or reductions in
amount receivable, shall be the result of such Lender's or Lenders' reasonable
allocation of the aggregate of such increases or reductions resulting from

                                                                              39

such event), then, not later than five Business Days following demand by such
Lender or Lenders (through the Administrative Agent), the Borrower shall pay to
the Administrative Agent for account of such Lender or Lenders, from time to
time as specified by such Lender or Lenders (through the Administrative Agent),
such additional amounts as shall be sufficient to compensate such Lender or
Lenders (through the Administrative Agent) for such increased costs or
reductions in amount. A statement as to such increased costs or reductions in
amount incurred by any such Lender or Lenders, submitted by such Lender or
Lenders to the Borrower shall be conclusive in the absence of manifest error as
to the amount thereof.

          5.07  U.S. Taxes.
                ---------- 

          (a)  The Borrower agrees to pay to each Lender that is not a U.S.
Person such additional amounts as are necessary in order that the net payment of
any amount due to such non-U.S. Person hereunder after deduction for or
withholding in respect of any U.S. Taxes imposed with respect to such payment
(or in lieu thereof, payment of such U.S. Taxes by such non-U.S. Person), will
not be less than the amount stated herein to be then due and payable, provided
                                                                      --------
that the foregoing obligation to pay such additional amounts shall not apply:

               (i)   to any payment to any Lender hereunder (other than to any
     Qualified Foreign Lender) unless such Lender is, on the
     Amendment/Restatement Effective Date (or on the date it becomes a Lender
     hereunder as provided in Section 12.06(b) hereof) and on the date of any
     change in the Applicable Lending Office of such Lender, either entitled to
     submit a Form 1001 (relating to such Lender and entitling it to a complete
     exemption from withholding on all interest to be received by it hereunder
     in respect of the Loans) or Form 4224 (relating to all interest to be
     received by such Lender hereunder in respect of the Loans),

               (ii)  to any payment to any Qualified Foreign Lender hereunder in
     respect of its Loan, unless such Qualified Foreign Lender (or, if such
     Qualified Foreign Lender is not the beneficial owner of such Loan, the
     beneficial owner thereof) is, on the Amendment/Restatement Effective Date
     (or on the date such Qualified Foreign Lender becomes a Lender as provided
     in Section 12.06(b) hereof) and on the date of any change in the Applicable
     Lending Office of such Lender, entitled to submit a Form W-8, together with
     an annual certificate stating that such Qualified Foreign Lender (or
     beneficial owner, as the case may be) is not a "bank" within the meaning of
     Section 881(c)(3)(A) of the Code, and such Qualified Foreign Lender (or
     beneficial owner, as the case may be) shall promptly notify the Borrower if
     at any time, such Qualified Foreign Lender (or beneficial owner, as the
     case may be) determines that it is no longer in a position to provide such
     certificate to the Borrower (or any other form of certification adopted by
     the relevant taxing authorities of the United States of America for such
     purposes), or

               (iii) to any U.S. Taxes imposed solely by reason of the failure
     by such non-U.S. Person (or, if such non-U.S. Person is not the beneficial
     owner of the relevant Loan, such beneficial owner) to comply with
     applicable certification, information, documentation or other reporting
     requirements concerning the nationality, residence, identity or connections
     with the United States of America of such non-U.S. Person (or beneficial
     owner, as the case may be) if such compliance is required by statute or
     regulation of the United States of America as a precondition to relief or

shall deliver to the Administrative Agent for delivery to such non-U.S. Person
evidence satisfactory to such Person of such deduction, withholding or payment
(as the case may be).

          (c)  Each such non-U.S. Person that is entitled to submit a Form 1001,
Form 4224 or Form W-8, together with a certificate stating that such Qualified
Foreign Lender (or beneficial owner, as the case may be) is not a "bank" within

certificate to the Borrower (or any other form of certification adopted by the
relevant taxing authorities of the United States of America for such purposes),
shall submit the same to the Administrative Agent and to the Borrower on the
Amendment/Restatement Effective Date (or on the date it becomes a Lender
hereunder as provided in Section 12.06(b) hereof) and annually thereafter.

          5.08  Replacement of Lenders.  If any Lender requests compensation
                ----------------------                                      
pursuant to Section 5.01, 5.06 or 5.07 hereof, or any Lender's obligation to
make or Continue, or to Convert Loans of any Type into, the other Type of Loan
shall be suspended pursuant to Section 5.01 or 5.03 hereof (any such Lender
requesting such compensation, or whose obligations are so suspended, being
herein called a "Requesting Lender"), the Borrower, upon three Business Days
                 -----------------                                          
notice, may require that such Requesting Lender transfer all of its right, title
and interest under this Agreement and such Requesting Lender's Notes to any bank
or other financial institution (a "Proposed Lender") identified by the Borrower
                                   ---------------

such Proposed Lender agrees to assume all of the obligations of such Requesting
Lender hereunder, and to purchase all of such Requesting Lender's Loans
hereunder for consideration equal to the aggregate outstanding principal amount
of such Requesting Lender's Loans, together with interest thereon to the date of
such purchase, and satisfactory arrangements are made for payment to such
Requesting Lender of all other amounts payable hereunder to such Requesting
Lender on or prior to the date of such transfer (including any fees accrued
hereunder and any amounts that would be payable under Section 5.05 hereof as if
all of such Requesting Lender's Loans were being prepaid in full on such date)
and (ii) if such Requesting Lender has requested compensation pursuant to
Section 5.01, 5.06 or 5.07 hereof, such Proposed Lender's aggregate requested
compensation, if any, pursuant to said Section 5.01, 5.06 or 5.07 with respect
to such Requesting Lender's Loans is lower than that of the Requesting Lender.
Subject to the provisions of Section 12.06(b) hereof, such Proposed Lender shall
be a "Lender" for all purposes hereunder.  Without prejudice to the survival of
any other agreement of the Borrower hereunder the agreements of the Borrower
contained in Sections 5.01, 5.06, 5.07 and 12.03 hereof (without duplication of
any payments made to such Requesting Lender by the Borrower or the Proposed
Lender) shall survive for the benefit of such Requesting Lender under this
Section 5.08 with respect to the time prior to such replacement.

                      --------- 

          6.01  The Guarantee.  The Guarantors hereby jointly and severally
                -------------                                              
guarantee to each Lender and the Administrative Agent and their respective
successors and assigns the prompt payment in full when due (whether at stated
maturity, by acceleration or otherwise) of the principal of and interest on the
Loans made by the Lenders to, and any Notes held by each Lender of, the Borrower
and all other amounts from time to time owing to the Lenders or the
Administrative Agent by the Borrower under this Agreement and under any Notes
and by any Obligor under any of the other Loan Documents, and all obligations of
the Borrower or any of its Subsidiaries to any Lender in respect of any Interest
Rate Protection Agreement, in each case strictly in accordance with the terms
thereof (such obligations being herein collectively called the "Guaranteed
                                                                ----------
Obligations").  The Guarantors hereby further jointly and severally agree that
- -----------                                                                   
if the Borrower shall fail to pay in full when due (whether at stated maturity,
by acceleration or otherwise) any of the Guaranteed Obligations, the Guarantors
will promptly pay the same, without any demand or notice whatsoever, and that in
the case of any extension of time of payment or renewal of any of the Guaranteed
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, by acceleration or otherwise) in accordance with the terms of
such extension or renewal.

          6.02  Obligations Unconditional.  The obligations of the Guarantors
                -------------------------                                    
under Section 6.01 hereof are absolute and unconditional, joint and several,
irrespective of the value, genuineness, validity, regularity or enforceability
of the obligations of the Borrower under this Agreement, any Notes or any other
agreement or instrument referred to herein or therein, or any substitution,
release or exchange of any other guarantee of or security for any of the
Guaranteed Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Section 6.02 that the obligations of the Guarantors
hereunder shall be absolute and unconditional, joint and several, under any and
all circumstances.  Without limiting the generality of the foregoing, it is
agreed that the occurrence of any one or more of the following shall not alter
or impair the liability of the Guarantors hereunder which shall remain absolute
and unconditional as described above:

               (i)      at any time or from time to time, without notice to the
     Guarantors, the time for any performance of or compliance with any of the
     Guaranteed Obligations shall be extended, or such performance or compliance
     shall be waived;

               (ii)     any of the acts mentioned in any of the provisions of
     this Agreement or any Notes or any other agreement or instrument referred
     to herein or therein shall be done or omitted;

               (iii)    the maturity of any of the Guaranteed Obligations shall
     be accelerated, or any of the Guaranteed Obligations shall be modified,
     supplemented or amended in any respect, or any right under this Agreement
     or any Notes or any other agreement or instrument referred to herein or
     therein shall be waived or any other guarantee of any of the Guaranteed
     Obligations or any security therefor shall be released or exchanged in
     whole or in part or otherwise dealt with; or

               (iv)     any lien or security interest granted to, or in favor
     of, the Administrative Agent or any Lender or Lenders as security for any
     of the Guaranteed Obligations shall fail to be perfected.

<PAGE>
 
                                                                              42

The Guarantors hereby expressly waive diligence, presentment, demand of payment,
protest and all notices whatsoever, and any requirement that the Administrative
Agent or any Lender exhaust any right, power or remedy or proceed against the
Borrower under this Agreement or any Notes or any other agreement or instrument
referred to herein or therein, or against any other Person under any other
guarantee of, or security for, any of the Guaranteed Obligations.  Anything
herein to the contrary notwithstanding, the maximum liability of each Subsidiary
Guarantor hereunder shall in no event exceed the amount which can be guaranteed
by such Subsidiary Guarantor under applicable federal and state laws relating to
the insolvency of debtors (after giving effect to the right of contribution
established in Section 6.08 hereof).

          6.03  Reinstatement.  The obligations of the Guarantors under this
                -------------                                               
Section 6 shall be automatically reinstated if and to the extent that for any
reason any payment by or on behalf of the Borrower in respect of the Guaranteed
Obligations is rescinded or must be otherwise restored by any holder of any of
the Guaranteed Obligations, whether as a result of any proceedings in bankruptcy
or reorganization or otherwise and the Guarantors jointly and severally agree
that they will indemnify the Administrative Agent and each Lender on demand for
all reasonable costs and expenses (including, without limitation, fees of
counsel) incurred by the Administrative Agent or such Lender in connection with
such rescission or restoration, including any such costs and expenses incurred
in defending against any claim alleging that such payment constituted a
preference, fraudulent transfer or similar payment under any bankruptcy,
insolvency or similar law.

          6.04  Subrogation.  The Guarantors hereby jointly and severally agree
                -----------                                                    
that until the payment and satisfaction in full of all Guaranteed Obligations
and the expiration and termination of the Commitments of the Lenders under this
Agreement they shall not exercise any right or remedy arising by reason of any
performance by them of their guarantee in Section 6.01 hereof, whether by
subrogation or otherwise, against the Borrower or any other guarantor of any of
the Guaranteed Obligations or any security for any of the Guaranteed
Obligations.

          6.05  Remedies.  The Guarantors jointly and severally agree that, as
                --------                                                      
between the Guarantors and the Lenders, the obligations of the Borrower under
this Agreement and any Notes may be declared to be forthwith due and payable as
provided in Section 10 hereof (and shall be deemed to have become automatically
due and payable in the circumstances provided in said Section 10) for purposes
of Section 6.01 hereof notwithstanding any stay, injunction or other prohibition
preventing such declaration (or such obligations from becoming automatically due
and payable) as against the Borrower and that, in the event of such declaration
(or such obligations being deemed to have become automatically due and payable),
such obligations (whether or not due and payable by the Borrower) shall
forthwith become due and payable by the Guarantors for purposes of said Section
6.01.

          6.06  Instrument for the Payment of Money.  Each Guarantor hereby
                -----------------------------------                        
acknowledges that the guarantee in this Section 6 constitutes an instrument for
the payment of money, and consents and agrees that any Lender or the
Administrative Agent, at its sole option, in the event of a dispute by such
Guarantor in the payment of any moneys due hereunder, shall have the right to
bring motion-action under New York CPLR Section 3213.

          6.07  Continuing Guarantee.  The guarantee in this Section 6 is a
                --------------------                                       
continuing guarantee, and shall apply to all Guaranteed Obligations whenever
arising.

          6.08  Rights of Contribution.  Each Subsidiary Guarantor hereby agrees
                ----------------------                                          
that to the extent that a Subsidiary Guarantor shall have paid more than its
proportionate share of any payment made hereunder, such Subsidiary Guarantor
shall be entitled to seek and receive contribution from and against any other
Subsidiary Guarantor hereunder which has not paid its proportionate share of
such payment.  
<PAGE>
 
                                                                              43

Each Subsidiary Guarantor's right of contribution shall be subject to the terms
and conditions of Section 6.04 hereof. The provisions of this Section 6.08 shall
in no respect limit the obligations and liabilities of any Subsidiary Guarantor
to the Administrative Agent and the Lenders, and each Subsidiary Guarantor shall
remain liable to the Administrative Agent and the Lenders for the full amount
guaranteed by such Subsidiary Guarantor hereunder.

          6.09  General Limitation on Guarantee Obligations.  In any action or
                -------------------------------------------                   
proceeding involving any state corporate law, or any state or Federal
bankruptcy, insolvency, reorganization or other law affecting the rights of
creditors generally, if the obligations of any Subsidiary Guarantor under
Section 6.01 hereof would otherwise, taking into account the provisions of
Section 6.08 hereof, be held or determined to be void, invalid or unenforceable,
or subordinated to the claims of any other creditors, on account of the amount
of its liability under said Section 6.01, then, notwithstanding any other
provision hereof to the contrary, the amount of such liability shall, without
any further action by such Subsidiary Guarantor, any Lender, the Administrative
Agent or any other Person, be automatically limited and reduced to the highest
amount that is valid and enforceable and not subordinated to the claims of other
creditors as determined in such action or proceeding.

          6.10  Waiver.  Each Guarantor waives all rights and defenses arising
                ------                                                        
out of an election of remedies by any Lender or the Administrative Agent, even
though that election of remedies, such as a nonjudicial foreclosure with respect
to security for a Guaranteed Obligation, has destroyed such Guarantor's right of
subrogation and reimbursement against the Borrower by the operation of Section
580d of the California Code of Civil Procedure or otherwise.  The provisions of
this Section 6.10 shall apply to each of the Loan Documents as if fully set
forth therein.

          a Multiemployer Plan that it is in reorganization or insolvency
          pursuant to Section 4241 or 4245 of ERISA or that it intends to
          terminate or has terminated under Section 4041A of ERISA;

                    (vi)  the adoption of an amendment to any Plan that,
          pursuant to Section 401(a)(29) of the Code or Section 307 of ERISA,
          would result in the loss of tax-exempt status of the trust of which
          such Plan is a part if the Company or an ERISA Affiliate fails to
          timely provide security to the Plan in accordance with the provisions
          of said Sections;

          (f)  promptly after the Borrower knows or has reason to believe that
     any Default has occurred, a notice of such Default describing the same in
     reasonable detail and, together with such notice or as soon thereafter as
     possible, a description of the action that the Borrower has taken or
     proposes to take with respect thereto; and

          (g)  from time to time such other information regarding the financial
     condition, operations, business or prospects of the Company or any of its
     Subsidiaries (including, without limitation, any Plan or Multiemployer Plan
     and any reports or other information required to be filed under ERISA) as
     any Lender or the Administrative Agent may reasonably request.

The Borrower will furnish to each Lender, at the time it furnishes each set of
financial statements pursuant to paragraph (a) or (b) above, a certificate of a
Responsible Officer of the Borrower (i) to the effect that, to the best
knowledge of such financial officer, no Default has occurred and is continuing
(or, if any Default has occurred and is continuing, describing the same in
reasonable detail and describing the action that the Borrower has taken or
proposes to take with respect thereto) and (ii) setting forth in reasonable
detail the computations necessary to determine whether the Borrower is in
compliance with Sections 9.07, 9.09, 9.10 and 9.11 hereof as of the end of the
respective quarterly fiscal period or fiscal year.

any governmental or regulatory authority or agency, and any material development
in respect of such legal or other proceedings, affecting the Company or any of
its Subsidiaries, except proceedings that, if adversely determined, would not
(either individually or in the aggregate) have a Material Adverse Effect.
Without limiting the generality of the foregoing, the Borrower will give to each
Lender notice of the assertion of any Environmental Claim by any Person against,
or with respect to the activities of, the Company or any of its Subsidiaries and
notice of any alleged violation of or non-compliance with any Environmental Laws
or any permits, licenses or authorizations, other than any Environmental Claim
or alleged violation that, if adversely determined, would not (either

          (b)  comply with the requirements of all applicable laws, rules,
     regulations and orders of governmental or regulatory authorities if failure
     to comply with such requirements could (either individually or in the
     aggregate) have a Material Adverse Effect;

          (c)  pay and discharge all taxes, assessments and governmental charges
     or levies imposed on it or on its income or profits or on any of its
     Property prior to the date on which penalties attach thereto, except for
     any such tax, assessment, charge or levy the payment of which is being
     contested in good faith and by proper proceedings and (unless the amount
     thereof is not material) against which adequate reserves are being
     maintained;

     case may be).

               ---------

insurance companies, and with respect to Property and risks of a character
usually maintained by corporations or other entities engaged in the same or
similar business similarly situated, against loss, damage and liability of the
kinds and in the amounts customarily maintained by such corporations or
entities; and furnish to each Lender, upon written request, full information as
to the insurance carried.

expressly permitted by Section 9.08 hereof.

          (c)  The Borrower will not, nor will it permit any of its Subsidiaries
to, convey, sell, lease, transfer or otherwise dispose of, in one transaction or
a series of transactions, any part of its business or Property, whether now

     specified in any note, agreement, indenture or other document evidencing or
     relating to any such Indebtedness shall occur if the effect of such event
     is to cause, or (with the giving of any notice or the lapse of time or
     both) to permit the holder or holders of such Indebtedness (or a trustee or
     agent on behalf of such holder or holders) to cause, such Indebtedness to
     become due, or to be prepaid in full (whether by redemption, purchase,
     offer to purchase or otherwise), prior to its stated maturity; or any
     Relevant Party shall default in the payment when due of any amount
     aggregating $5,000,000 or more under any Interest Rate Protection
     Agreement; or any event specified in any Interest Rate Protection Agreement

     any notice or the lapse of time or both) to permit, termination or
     liquidation payment or payments aggregating $1,000,000 or more to become
     due; or

          (c)  Any representation, warranty or certification made or deemed made
     herein or in any other Loan Document (or in any modification or supplement
     hereto or thereto) by any Relevant Party, or any certificate furnished to
     any Lender or the Administrative Agent pursuant to the provisions hereof or
     thereof, shall prove to have been false or misleading as of the time made
     or furnished in any material respect; or

          (d)  The Borrower, the Company (as applicable) or the Parent Guarantor
     (as applicable) shall default in the performance of any of its obligations

     notice thereof to the Borrower by the Administrative Agent or any Lender
     (through the Administrative Agent); or

          (e)  Any Relevant Party shall admit in writing its inability to, or be

     purpose of effecting any of the foregoing; or

          (g)  A proceeding or case shall be commenced, without the application
     or consent of the affected Relevant Party, in any court of competent
     jurisdiction, seeking (i) its reorganization, liquidation, dissolution,
     arrangement or winding-up, or the composition or readjustment of its debts,
     (ii) the appointment of a receiver, custodian, trustee, examiner,
     liquidator or the like of such Relevant Party or of all or any substantial

     covered by insurance where the insurer has admitted liability in respect of
     such judgment), shall be rendered by one or more courts, administrative
     tribunals or other bodies having jurisdiction against any Relevant Party
     and the same shall not be discharged (or provision shall not be made for
     such discharge), or a stay of execution thereof shall not be procured,
     within 30 days from the date of entry thereof and such Relevant Party shall
     not, within said period of 30 days, or such longer period during which

     opinion of the Majority Lenders shall be reasonably likely to incur a
     liability to a Plan, a Multiemployer Plan or the PBGC (or any combination
     of the foregoing) that, in the determination of the Majority Lenders, would
     (either individually or in the aggregate) have a Material Adverse Effect;
     or

          (j)  A reasonable basis shall exist for the assertion against the
     Parent Guarantor or any of its Subsidiaries, or any predecessor in interest
     of the Parent Guarantor or any of its Subsidiaries or Affiliates, of (or
     there shall have been asserted against the Parent Guarantor or any of its
     Subsidiaries) an Environmental Claim that, in the judgment of the Majority
     Lenders is reasonably likely to be determined adversely to the Company or
     any of its Subsidiaries, and the

     amount thereof (either individually or in the aggregate) is reasonably
     likely to have a Material Adverse Effect (insofar as such amount is payable
     by the Company or any of its Subsidiaries but after deducting any portion
     thereof that is reasonably expected to be paid by other creditworthy
     Persons jointly and severally liable therefor); or

            (k)  (i) prior to the initial registered public offering of the
     Parent Guarantor's common stock, (x) the H&F Affiliated Parties shall cease
     to own or control, directly or indirectly, more than 51% of the capital
     stock of the Parent Guarantor, (y) the Parent Guarantor shall cease to own
     or control directly or indirectly all of the capital stock of the Borrower
     or (z) a Specified Change of Control shall occur, or (ii) on and after the
     date of the initial registered public offering of the Parent Guarantor's

     directly or indirectly, more than 35% of the capital stock of the Parent
     Guarantor, (x) any Person or "group" (as such terms are used in Sections
     13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the
     "Exchange Act")), other than the H&F Affiliated Parties, shall become, or
      ------------ 
     obtain rights (whether by means of warrants, options or otherwise) to
     become, the "beneficial owner" (as defined in Rules 13(d)-3 and 13(d)-5
     under the Exchange Act), directly or indirectly, of a percentage of the
     outstanding shares of common stock of the Parent Guarantor which is greater
     than the percentage of the outstanding shares of common stock of the Parent
     Guarantor beneficially owned by the H&F Affiliated Parties, (y) the Parent
     Guarantor shall cease to own or control directly or indirectly all of the
     capital stock of the Borrower or (z) a Specified Change of Control shall

     stock of the Borrower and its Subsidiaries shall at any time not constitute
     a valid and perfected Lien in favor of the Administrative Agent, free and
     clear of all other Liens, or, (ii) except for expiration in accordance with
     its terms, any of the Security Documents shall for whatever reason be
     terminated or cease to be in full force and effect, or the enforceability
     thereof shall be contested by any Obligor, or (iii) Section 6 shall cease,
     for any reason, to be in full force and effect or any Guarantor shall so
     assert; or

THEREUPON:  (1) in the case of an Event of Default other than one referred to in
clause (f) or (g) of this Section 10 with respect to any Obligor, the
Administrative Agent may (and upon the request of the Majority Lenders shall),
by notice to the Borrower, terminate the Commitments and/or declare the
principal amount then outstanding of, and the accrued interest on, the Loans,
the Reimbursement Obligations and all other amounts payable by the Obligors
hereunder and under any Notes (including, without limitation, any amounts
payable under Section 5.05 or 5.06 hereof) to be forthwith due and payable,
whereupon such amounts shall be immediately due and payable without presentment,
demand, protest or other formalities of any kind, all of which are hereby
expressly waived by each Obligor; and (2) in the case of the occurrence of an
Event of Default referred to in clause (f) or (g) of this Section 10 with
respect to any Obligor, the Commitments shall automatically be terminated and
the principal amount then outstanding of, and the accrued interest on, the
Loans, the Reimbursement Obligations and all other amounts payable by the
Obligors hereunder and under any Notes (including, without limitation, any
amounts payable under Section 5.05 or 5.06 hereof) shall automatically become
immediately due and payable without presentment, demand, protest or other
formalities of any kind, all of which are hereby expressly waived by each
Obligor.

                                                                              71

          In addition, upon the occurrence and during the continuance of any
Event of Default (if the Administrative Agent has declared the principal amount
then outstanding of, and accrued interest on, the Revolving Credit Loans and all
other amounts payable by the Borrower hereunder and under any Notes to be due
and payable), the Borrower agrees that it shall, if requested by the
Administrative Agent or the Majority Revolving Credit Lenders through the
Administrative Agent (and, in the case of any Event of Default referred to in
clause (f) or (g) of this Section 10 with respect to the Borrower or the Parent
Guarantor, forthwith, without any demand or the taking of any other action by
the Administrative Agent or such Lenders) provide cover for the Letter of Credit
Liabilities by paying to the Administrative Agent immediately available funds in
an amount equal to the then aggregate undrawn face amount of all Letters of
Credit, which funds shall be held by the Administrative Agent in the Collateral
Account as collateral security in the first instance for the Letter of Credit
Liabilities and be subject to withdrawal only as therein provided.


          Section 11.  The Administrative Agent.
                       ------------------------ 

          11.01  Appointment, Powers and Immunities.  Each Lender hereby
                 ----------------------------------                     
appoints and authorizes the Administrative Agent to act as its agent hereunder
and under the other Loan Documents with such powers as are specifically
delegated to the Administrative Agent by the terms of this Agreement and of the
other Loan Documents, together with such other powers as are reasonably
incidental thereto.  The Administrative Agent (which term as used in this
sentence and in Section 11.05 and the first sentence of Section 11.06 hereof
shall include reference to its affiliates and its own and its affiliates'
officers, directors, employees and agents):

          (a)    shall have no duties or responsibilities except those expressly
     set forth in this Agreement and in the other Loan Documents, and shall not
     by reason of this Agreement or any other Loan Document be a trustee for any
     Lender;

          (b)    shall not be responsible to the Lenders for any recitals,
     statements, representations or warranties contained in this Agreement or in
     any other Loan Document, or in any certificate or other document referred
     to or provided for in, or received by any of them under, this Agreement or
     any other Loan Document, or for the value, validity, effectiveness,
     genuineness, enforceability or sufficiency of this Agreement, any Note or
     any other Loan Document or any other document referred to or provided for
     herein or therein or for any failure by the Borrower or any other Person to
     perform any of its obligations hereunder or thereunder;

          (c)    shall not, except to the extent expressly instructed by the
     Majority Lenders with respect to collateral security under the Security
     Documents, be required to initiate or conduct any litigation or collection
     proceedings hereunder or under any other Loan Document; and

          (d)    shall not be responsible for any action taken or omitted to be
     taken by it hereunder or under any other Loan Document or under any other
     document or instrument referred to or provided for herein or therein or in
     connection herewith or therewith, except for its own gross negligence or
     willful misconduct.

The Administrative Agent may employ agents and attorneys-in-fact and shall not
be responsible for the negligence or misconduct of any such agents or attorneys-
in-fact selected by it in good faith.  The Administrative Agent may deem and
treat the payee (or Registered Holder, as the case may be) of a Note as the
holder thereof for all purposes hereof unless and until a notice of the
assignment or transfer thereof shall have been filed with the Administrative
Agent.

                                                                              72

          11.02  Reliance by Administrative Agent.  The Administrative Agent
                 --------------------------------                           
shall be entitled to rely upon any certification, notice or other communication
(including, without limitation, any thereof by telephone, telecopy, telegram or
cable) reasonably believed by it to be genuine and correct and to have been
signed or sent by or on behalf of the proper Person or Persons, and upon advice
and statements of legal counsel, independent accountants and other experts
selected by the Administrative Agent.  As to any matters not expressly provided
for by this Agreement or any other Loan Document, the Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder or thereunder in accordance with instructions given by the Majority
Lenders or, if provided herein, in accordance with the instructions given by the
Majority Revolving Credit Lenders, the Majority Term Lenders or all of the
Lenders as is required in such circumstance, and such instructions of such
Lenders and any action taken or failure to act pursuant thereto shall be binding
on all of the Lenders.

          11.03  Defaults.  The Administrative Agent shall not be deemed to have
                 --------                                                       
knowledge or notice of the occurrence of a Default unless the Administrative
Agent has received notice from a Lender or the Borrower specifying such Default
and stating that such notice is a "Notice of Default".  In the event that the
Administrative Agent receives such a notice of the occurrence of a Default, the
Administrative Agent shall give prompt notice thereof to the Lenders.  The
Administrative Agent shall (subject to Section 11.07 hereof) take such action
with respect to such Default as shall be directed by the Majority Lenders or, if
provided herein, the Majority Revolving Credit Lenders or the Majority Term
Lenders, provided that, unless and until the Administrative Agent shall have
         --------                                                           
received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default as it shall deem advisable in the best interest of the Lenders
except to the extent that this Agreement expressly requires that such action be
taken, or not be taken, only with the consent or upon the authorization of the
Majority Lenders, the Majority Revolving Credit Lenders, the Majority Term
Lenders or all of the Lenders.

          11.04  Rights as a Lender.  With respect to its Commitments and the
                 ------------------                                          
Loans made by it, Chase (and any successor acting as Administrative Agent) in
its capacity as a Lender hereunder shall have the same rights and powers
hereunder as any other Lender and may exercise the same as though it were not
acting as the Administrative Agent, and the term "Lender" or "Lenders" shall,
unless the context otherwise indicates, include the Administrative Agent in its
individual capacity.  Chase (and any successor acting as Administrative Agent)
and its affiliates may (without having to account therefor to any Lender) accept
deposits from, lend money to, make investments in and generally engage in any
kind of banking, trust or other business with the Obligors (and any of their
Subsidiaries or Affiliates) as if it were not acting as the Administrative
Agent, and Chase (and any such successor) and its affiliates may accept fees and
other consideration from the Obligors for services in connection with this
Agreement or otherwise without having to account for the same to the Lenders.

          11.05  Indemnification.  The Lenders agree to indemnify the
                 ---------------                                     
Administrative Agent (to the extent not reimbursed under Section 12.03 hereof,
but without limiting the obligations of the Borrower under said Section 12.03)
ratably in accordance with the aggregate principal amount of the Loans and
Reimbursement Obligations held by the Lenders (or, if no Loans or Reimbursement
Obligations are at the time outstanding, ratably in accordance with their
respective Commitments), for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever that may be imposed on, incurred by or
asserted against the Administrative Agent (including by any Lender) arising out
of or by reason of any investigation in or in any way relating to or arising out
of this Agreement or any other Loan Document or any other documents contemplated
by or referred to herein or therein or the transactions contemplated hereby or
thereby (including, without limitation, the costs and expenses that the Borrower
is obligated to pay under Section 12.03 hereof, but excluding, unless a Default
has occurred and is continuing, normal administrative costs and expenses
incident to the performance of its agency duties hereunder) or the 
<PAGE>
 
                                                                              73

enforcement of any of the terms hereof or thereof or of any such other
documents, provided that no Lender shall be liable for any of the foregoing to 
           --------
the extent they arise from the gross negligence or willful misconduct of the
party to be indemnified.

          11.06  Non-Reliance on Administrative Agent and Other Lenders.  Each
                 ------------------------------------------------------       
Lender agrees that it has, independently and without reliance on the
Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own credit analysis of the
Parent Guarantor and its Subsidiaries and decision to enter into this Agreement
and that it will, independently and without reliance upon the Administrative
Agent or any other Lender, and based on such documents and information as it
shall deem appropriate at the time, continue to make its own analysis and
decisions in taking or not taking action under this Agreement or under any other
Loan Document.  The Administrative Agent shall not be required to keep itself
informed as to the performance or observance by any Obligor of this Agreement or
any of the other Loan Documents or any other document referred to or provided
for herein or therein or to inspect the Properties or books of the Parent
Guarantor or any of its Subsidiaries.  Except for notices, reports and other
documents and information expressly required to be furnished to the Lenders by
the Administrative Agent hereunder or under the Security Documents, the
Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the affairs, financial
condition or business of the Parent Guarantor or any of its Subsidiaries (or any
of their affiliates) that may come into the possession of the Administrative
Agent or any of its affiliates.

          11.07  Failure to Act.  Except for action expressly required of the
                 --------------                                              
Administrative Agent hereunder and under the other Loan Documents, the
Administrative Agent shall in all cases be fully justified in failing or
refusing to act hereunder and thereunder unless it shall receive further
assurances to its satisfaction from the Lenders of their indemnification
obligations under Section 11.05 hereof against any and all liability and expense
that may be incurred by it by reason of taking or continuing to take any such
action.

          11.08  Resignation or Removal of Administrative Agent.  Subject to the
                 ----------------------------------------------                 
appointment and acceptance of a successor Administrative Agent as provided
below, the Administrative Agent may resign at any time by giving notice thereof
to the Lenders and the Borrower and the Parent Guarantor, and the Administrative
Agent may be removed at any time with or without cause by the Majority Lenders.
Upon any such resignation or removal, the Majority Lenders shall have the right
to appoint a successor Administrative Agent.  If no successor Administrative
Agent shall have been so appointed by the Majority Lenders and shall have
accepted such appointment within 30 days after the retiring Administrative
Agent's giving of notice of resignation or the Majority Lenders' removal of the
retiring Administrative Agent, then the retiring Administrative Agent may, on
behalf of the Lenders, appoint a successor Administrative Agent, that shall be a
bank that has an office in New York, New York with a combined capital and
surplus of at least $500,000,000.  Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder.  After any retiring Administrative Agent's
resignation or removal hereunder as Administrative Agent, the provisions of this
Section 11 shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as the Administrative
Agent.

          11.09  Consents under Other Loan Documents.  Except as otherwise
                 -----------------------------------                      
provided in Section 12.04 hereof with respect to this Agreement, the
Administrative Agent may, with the prior consent of the Majority Lenders (but
not otherwise), consent to any modification, supplement or waiver under any of
the Loan Documents, provided that, without the prior consent of each Lender, the
                    --------                                                    
Administrative Agent

                                                                              74

shall not (except as provided herein, in the Security Documents or in the
Assumption Agreements) release any collateral or otherwise terminate any Lien
under any Security Document providing for collateral security, agree to
additional obligations being secured by such collateral security (unless the
Lien for such additional obligations shall be junior to the Lien in favor of the
other obligations secured by such Security Document, in which event the
Administrative Agent may consent to such junior Lien provided that it obtains
the consent of the Majority Lenders thereto), alter the relative priorities of
the obligations entitled to the benefits of the Liens created under the Security
Documents, except that no such consent shall be required, and the Administrative
Agent is hereby authorized, to release any Lien covering Property that is the
subject of either a disposition of Property permitted hereunder or a disposition
to which the Majority Lenders have consented.

          Section 12.  Miscellaneous.
                       ------------- 

          12.01  Waiver.  No failure on the part of the Administrative Agent or
                 ------                                                        
any Lender to exercise and no delay in exercising, and no course of dealing with
respect to, any right, power or privilege under this Agreement or any Note shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, power or privilege under this Agreement or any Note preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The remedies provided herein are cumulative and not exclusive of any remedies
provided by law.

          Each Obligor irrevocably waives, to the fullest extent permitted by
applicable law, any claim that any action or proceeding commenced by the
Administrative Agent or any Lender relating in any way to this Agreement should
be dismissed or stayed by reason, or pending the resolution, of any action or
proceeding commenced by any Obligor relating in any way to this Agreement
whether or not commenced earlier.  To the fullest extent permitted by applicable
law, the Obligors shall take all measures necessary for any such action or
proceeding commenced by the Administrative Agent or any Lender to proceed to
judgment prior to the entry of judgment in any such action or proceeding
commenced by any Obligor.

          12.02  Notices.  All notices, requests and other communications
                 -------                                                 
provided for herein and under the Security Documents (including, without
limitation, any modifications of, or waivers, requests or consents under, this
Agreement) shall be given or made in writing (including, without limitation, by
telecopy) delivered to the intended recipient addressed as follows in the case
of the Obligors and the Administrative Agent and as set forth in an
administrative questionnaire delivered to the Administrative Agent in the case
of each Lender (which shall be made available to the Borrower upon request), or

case of any waiver, the Borrower, the Lenders and the Administrative Agent

other Loan Documents, and any Default or Event of Default waived shall be deemed
to be cured and not continuing; no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.

          Anything in this Agreement to the contrary notwithstanding, no waiver
or modification of any provision of this Agreement that has the effect (either
immediately or at some later time) of enabling the Borrower to satisfy a

Commitments unless the Majority Revolving Credit Lenders shall have concurred

and inure to the benefit of the parties hereto and their respective successors
and permitted assigns.

          12.06  Assignments and Participations.
                 ------------------------------ 

          (a)  No Obligor may assign any of its rights or obligations hereunder
or under any Notes without the prior consent of all of the Lenders and the
Administrative Agent.

          (b)  Any Lender may, in the ordinary course of its business and in
accordance with applicable law, at any time and from time to time assign to any
Lender or any Affiliate thereof or, with the prior written consent of the
Borrower and the Administrative Agent (which in each case shall not be
unreasonably withheld), to an additional bank or financial institution or
investment funds which invest in credit facilities (an "Assignee") all or any
                                                        --------             
part of its rights and obligations under this Agreement and any Notes,
including, without limitation, its Revolving Credit Commitment, Term Loan
Commitments, Loans, and, if such Lender is a Revolving Credit Lender, its Letter
of Credit Interest (pursuant to an Assignment and Acceptance, substantially in
the form of Exhibit E, executed by such Assignee, such assigning Lender (and, in
the case of an Assignee that is not then a Lender or an Affiliate thereof, by
the Borrower and the Administrative Agent) and delivered to the Administrative
Agent for its acceptance and recording in the Register;  provided that (unless
                                                         --------             
the Borrower and the Administrative Agent otherwise consent in writing)

               (i)   except to the extent the Borrower and the Administrative
     Agent shall otherwise consent, any such partial assignment (other than to
     another Lender) shall be in an amount at least equal to $5,000,000;

               (ii)  each such assignment by a Lender of its Revolving Credit
     Loans, Revolving Credit Note, Revolving Credit Commitment or Letter of
     Credit Interest shall be made in such manner so that the same portion of
     its Revolving Credit Loans, Revolving Credit Note, Revolving Credit
     Commitment and Letter of Credit Interest is assigned to the respective
     assignee;

               (iii) each such assignment by a Lender of its Tranche A Term
     Loans or Tranche A Term Loan Commitment shall be made in such manner so
     that the same portion of its Tranche A Term Loans and Tranche A Term Loan
     Commitment is assigned to the respective assignee; and

               (iv)  each such assignment by a Lender of its Tranche B Term
     Loans or Tranche B Term Loan Commitment shall be made in such manner so
     that the same portion of its Tranche B Term Loans and Tranche B Term Loan
     Commitment is assigned to the respective assignee.
<PAGE>
 
                                                                              79

Upon such execution, delivery, acceptance and recording, from and after the
effective date determined pursuant to such Assignment and Acceptance, (x) the
Assignee thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
with a Revolving Credit Commitment and, if applicable, Letter of Credit Interest
(or a portion thereof) and the Term Loan Commitment and the Term Loans, as set
forth therein, and (y) the assigning Lender thereunder shall be released from
its obligations under this Agreement to the extent that such obligations shall
have been expressly assumed by the Assignee pursuant to such Assignment and
Acceptance (and, in the case of an Assignment and Acceptance covering all or the
remaining portion of an assigning Lender's rights and obligations under this
Agreement, such assigning Lender shall cease to be a party hereto but shall
nevertheless continue to be entitled to the benefits of Sections 5.01, 5.05,
5.06, 5.07 and 12.03).  Notwithstanding the foregoing, no Assignee, which as of
the date of any assignment to it pursuant to this Section 12.06(b) would be
entitled to receive any greater payment under Section 5.01 or 5.07 than the
assigning Lender would have been entitled to receive as of such date under such
Sections with respect to the rights assigned, shall be entitled to receive such
payments unless the Borrower has expressly consented in writing to waive the
benefit of this provision at the time of the assignment.

          (c)  A Lender may sell or agree to sell to one or more other Persons
(each a "Participant") a participation in all or any part of any Loans or Letter
         -----------                                                            
of Credit Interest held by it, or in its Commitments, provided that such
                                                      --------          
Participant shall not have any rights or obligations under this Agreement or any
Note or any other Loan Document (the Participant's rights against such Lender in
respect of such participation to be those set forth in the agreements executed
by such Lender in favor of the Participant).  All amounts payable by the
Borrower to any Lender under Section 5 hereof in respect of Loans, Letter of
Credit Interest held by it, and its Commitments, shall be determined as if such
Lender had not sold or agreed to sell any participations in such Loans, Letter
of Credit Interest and Commitments, and as if such Lender were funding each of
such Loan, Letter of Credit Interest and Commitments in the same way that it is
funding the portion of such Loan, Letter of Credit Interest and Commitments in
which no participations have been sold.  In no event shall a Lender that sells a
participation agree with the Participant to take or refrain from taking any
action hereunder or under any other Loan Document except that such Lender may
agree with the Participant that it will not, without the consent of the
Participant, agree to (i) increase or extend the term of such Lender's related
Commitment or extend the amount or date of any scheduled reduction of such
Commitment pursuant to Section 2.04 hereof, (ii) extend the date fixed for the
payment of principal of or interest on the related Loan or Loans, Reimbursement
Obligations or any portion of any fee hereunder payable to the Participant,
(iii) reduce the amount of any such payment of principal, (iv) reduce the rate
at which interest is payable thereon, or any fee hereunder payable to the
Participant, to a level below the rate at which the Participant is entitled to
receive such interest or fee or (v) consent to any modification, supplement or
waiver hereof or of any of the other Loan Documents to the extent that the same,
under Section 11.09 or 12.04 hereof, requires the consent of each Lender.

          (d)  In addition to the assignments and participations permitted under
the foregoing provisions of this Section 12.06, any Lender may (without notice
to the Borrower, the Administrative Agent or any other Lender and without
payment of any fee) (i) assign and pledge all or any portion of its Loans and
its Notes to any Federal Reserve Bank as collateral security pursuant to
Regulation A and any Operating Circular issued by such Federal Reserve Bank and
(ii) assign all or any portion of its rights under this Agreement and its Loans
and its Notes to an affiliate.  No such assignment shall release the assigning
Lender from its obligations hereunder.

          (e)  A Lender may furnish any information concerning the Borrower or
any of its Subsidiaries in the possession of such Lender from time to time to
assignees and participants (including prospective assignees and participants),
subject, however, to the provisions of Section 12.12(b) hereof.

                                                                              80

          (f)  Anything in this Section 12.06 to the contrary notwithstanding,
no Lender may assign or participate any interest in any Loan or Reimbursement
Obligation held by it hereunder to the Borrower or any of its Affiliates or
Subsidiaries without the prior consent of each Lender.

          (g)  The Administrative Agent, on behalf of the Borrower, shall
maintain at its Principal Office a copy of each Assignment and Acceptance
delivered to it and a register (the "Register") for the recordation of the names
                                     --------                                   
and addresses of the Lenders and the Revolving Credit Commitment and Term Loan
Commitments of, and the principal amount of the Loans owing to, and any Notes
evidencing such Loans owned by, each Lender from time to time.  Notwithstanding
anything in this Agreement to the contrary, the Borrower, the Administrative
Agent and the Lenders shall treat each Person whose name is recorded in the
Register as the owner of any Loan, any Notes and the Revolving Credit
Commitments and Term Loan Commitments recorded therein for all purposes of this
Agreement.  The Register shall be available for inspection by the Borrower or
any Lender at any reasonable time and from time to time upon reasonable prior
notice.

          (h)  Notwithstanding anything in this Agreement to the contrary, no
assignment under Section 12.06(b) of any rights or obligations under or in
respect of the Loans or any Notes evidencing such Loans shall be effective
unless and until the Administrative Agent shall have recorded the assignment
pursuant to Section 12.06(g).  Upon its receipt of an Assignment and Acceptance
executed by an assigning Lender and an Assignee (and, in the case of an Assignee
that is not then a Lender or an Affiliate thereof, by the Borrower and the
Administrative Agent), together with payment to the Administrative Agent of a
registration and processing fee of $3,500, the Administrative Agent shall (i)
promptly accept such Assignment and Acceptance and (ii) on the effective date
determined pursuant thereto record the information contained therein in the
Register and give prompt notice of such acceptance and recordation to the
Lenders and the Borrower.  On or prior to such effective date, the assigning
Lender shall surrender any outstanding Notes held by it all or a portion of
which are being assigned, and the Borrower, at its own expense, shall, upon the
request to the Administrative Agent by the assigning Lender or the Assignee, as
applicable, execute and deliver to the Administrative Agent (in exchange for the
outstanding Notes of the assigning Lender, if any) a new Revolving Credit Note,
Tranche A Term Note and/or Tranche B Term Note, as the case may be (such new

Lender may cease to be a "Lender" hereunder. In addition, each representation
and warranty made, or deemed to be made by a notice of any extension of credit
(whether by means of a Loan or a Letter of Credit) herein or pursuant hereto
shall survive the making of such representation and warranty, and no Lender
shall be deemed to have waived, by reason of making any extension of credit
hereunder (whether by means of a Loan or a Letter of Credit) any Default that
may arise by reason of such representation or warranty proving to have been
false or misleading, notwithstanding that such Lender or the Administrative
Agent may have had notice or knowledge or reason to believe that such
representation or warranty was false or misleading at the time such extension of
credit was made.

any Lender or the Administrative Agent be obligated or required to return any
materials furnished by the Parent Guarantor or the Borrower.  The obligations of
each Lender under this Section 12.12 shall supersede and replace the obligations
of such Lender under the confidentiality letter in respect of this financing

Amendment/Restatement Effective Date; in addition, the obligations of any
assignee that has executed a Confidentiality Agreement in the form of Exhibit D

                             EMPLOYMENT AGREEMENT
                             --------------------

     THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into as of
July 1, 1996 by and between AHI HOLDING CORP., a Delaware corporation (the
"Company") and Robert L. Krakoff ("Executive").

     WHEREAS, the Company has acquired, pursuant to a Merger Agreement dated as
of April 12, 1996, and currently operates certain trade exposition and
publishing businesses; and

     WHEREAS, the Company wishes to employ Executive and Executive is prepared
to serve in those capacities required by the Company.

     NOW, THEREFORE, the parties agree as follows:

     1.   Position and Authority.  The Company agrees to employ the Executive, 
          ----------------------
and the Executive accepts such employment and agrees to serve the Company as the
Chairman of the Board of Directors and Chief Executive Officer of the Company
and its respective Subsidiaries, for the compensation and benefits detailed in
Sections 3 and 4 hereof.  It is understood that the Executive will report
directly to the Board of Directors and that no other officer shall regularly so
report.  The Executive shall be the highest ranking officer of the Company and
shall have (in all cases subject to the overall authority and control of the
Board of Directors) such authority as is typical for executives having similar
positions in similar companies.  A "Subsidiary" shall be any company in which
the Company beneficially owns more than 50% of the voting power of such
company's outstanding voting securities.

     2.   Duties.  Executive shall devote substantially all of his business time
          ------                                                                
(subject to four weeks of vacation, or such greater amount as is authorized by
the Board of Directors) to the affairs of the Company during the employment
term, except as may be consented to by the Board of Directors.  Notwithstanding
the foregoing, to the extent that it does not materially interfere with the
performance of his duties, Executive may devote such business time as is
reasonably necessary to his duties as a director of not more than two business
corporations not affiliated with the Company, and Executive may devote business
time to any charitable or not-for-profit activities.  Executive shall perform
such duties and responsibilities as the Board of Directors of the Company may
from time to time reasonably determine, provided that such duties and
responsibilities are consistent with Executive's position as Chief Executive
Officer of the Company and do not diminish Executive's authority as set forth in
Section 1 hereof.  Executive will not be required to relocate his permanent
residence outside of Boston, Massachusetts.
<PAGE>
 
     3.   Base Compensation and Bonus.
          --------------------------- 

          (a)  Base Composition.  Executive will be compensated at a base salary
               ----------------                                                 
rate of $400,000 per year (or such higher rate as may be set from time to time
by the Board of Directors in its discretion) during the employment term.  Base
compensation will be paid in installments on the same schedule as the Company's
Subsidiaries generally pay their employees.  All compensation and benefits will
be subject to reduction by all federal, state, local and other withholdings and
similar taxes and payments required by applicable law.

          (b)  Bonus for the Fiscal Year Ended December 31, 1996.  The Executive
               -------------------------------------------------                
shall receive a bonus of $100,000 for the fiscal year ended December 31, 1996.

          (c)  Bonus for Subsequent Fiscal Years.  In addition to Executive's 
               ---------------------------------
base compensation, Executive will receive bonus compensation based on the
relationship between the Company's actual earnings before interest, taxes,
depreciation and amortization ("EBITDA") for each fiscal year starting with the
fiscal year ending December 31, 1997 (determined based on the Company's audited
financial statements for such fiscal year) and the EBITDA set for such year in
the Company "Adjusted Business Plan" (as defined below) as follows:

<TABLE>
<CAPTION>
         Actual EBITDA                   Bonus
         as a Percentage                 (as a Percentage
         of Plan                         of Base Salary
         ---------------                 ----------------
         <S>                             <C> 
         Less than 80%                   No bonus

         100%                            50% of Base Salary

         120% or More                    100% of Base Salary
</TABLE>

If actual EBITDA as a percentage of the Company's Adjusted Business Plan falls
between 80% and 120%, the amount of bonus shall be pro rated on a straight-line
basis.  In no case shall bonus payable under this Section 3(c) exceed 100% of
Base Salary unless agreed to by the Board of Directors in its absolute
discretion.

     The "Adjusted Business Plan" shall be the Company's business plan for the
fiscal year in question as approved by the Board of Directors with the consent
of Executive, appropriately adjusted for acquisitions or dispositions during the
year as determined by the Board of Directors in good faith.  If the Board and
the Executive do not adopt a mutually satisfactory business plan prior to the
beginning of any fiscal year, the business plan for purposes of this Section
3(c) shall be the business plan submitted to Chemical 

                                       2
<PAGE>
 
Bank and dated May, 1996, subject to adjustment as provided above for
acquisitions and dispositions occurring after May 31, 1996.

     Any bonus payable under this Section 3(c) shall be paid not later than 60
days after the applicable fiscal year end.

     4.   Benefits.
          -------- 

          (a)  During Executive's employment by the Company, Executive will
receive the same (or substantially similar) employee benefits to those provided
by the Company or its Subsidiaries to other members of senior management from
time to time, including, without limitation, medical and dental insurances,
disability insurance and life insurance (the latter in an amount of not less
than $1,200,000); provided, that regardless of whether or not paid for other
members of senior management, the Company shall pay the entire amount of any
premium for life insurance in an amount of $1,200,000 and disability insurance
provided by the Company to Executive under this Agreement.

          (b)  During and after the employment term the Company agrees that if
Executive is made a party, or compelled to testify or otherwise participate in,
any action, suit or proceeding (a "Proceeding"), by reason of the fact that he
is or was a director or officer of the Company or any of its Subsidiaries,
Executive shall be indemnified by the Company as provided in Section 145 of the
Delaware General Corporation Law or (but not to any lesser extent) as authorized
by the Company's certificate of incorporation or bylaws or resolutions of the
Company's Board of Directors against all cost, expense, liability, damage and
loss reasonably incurred or suffered by Executive in connection therewith, and
such indemnification shall continue as to Executive even if he has ceased to be
a director or officer of the Company or Subsidiary for the period of any
applicable statute of limitations or, if longer, for the period in which any
such Proceeding which commenced within the period of any such statute of
limitations is pending.  The Company shall advance to Executive all reasonable
costs and expenses incurred by him in connection with a Proceeding within 20
days after receipt by the Company of a written request for such advance.  Such
request shall include an itemized list of the costs and expenses and an
undertaking by Executive to repay the amount of such advance if it shall
ultimately be determined, in a final judgment for which the time to appeal has
expired, that, pursuant to applicable law, he is not entitled to be indemnified
against such costs and expenses.

          (c)  The Company will reimburse Executive for his reasonable and
customary business expenses, including travel, accommodations and meals. Such
reimbursement shall include the reasonable cost of travel to and from Boston
(other than commuting expenses) and accommodations and meals when outside of
Boston.

                                       3
<PAGE>
 
          (d)  The Company shall lease in Boston office space, reasonably
satisfactory to Executive, at which the Company's principal executive offices
shall be located, including Executive's principal office.  Any leasehold
improvements reasonably necessary to prepare such office space for use as the
Company's principal executive office, and all reasonably necessary office
equipment, shall be paid for by the Company.  The Company shall provide
Executive with a secretary and such additional office staff as the Board of
Directors and Executive shall determine.

     5.   Stock Option Plan.  The Company shall establish a Stock Option Plan 
          -----------------
for employees of the Company or its Subsidiaries other than Executive or other
members of AHI Advanstar LLC ("LLC"), which plan shall permit the grant of
options covering (as of May 15, 1997) not less than 7,452 shares (as adjusted
for stock splits, stock dividends, reverse stock splits and similar transactions
on such terms as the Board deems appropriate).  In the event that additional
capital is invested in the Company after May 15, 1997 by any person up to a
total aggregate investment (including capital already invested) of $200,000,000,
additional shares will be made available for the grant of options under the
option plan such that the number of Company shares subject to such options
equals the number of shares of Common Stock of the Company outstanding
multiplied by a percentage (expressed as a decimal) equal to the difference
between (A) and (B), where (A) is 18.0% (reduced by the amount, if any, by which
the Carried Interest Percentage of Solomon under the LLC Operating Agreement is
less than 2.5%) and (B) is the aggregate Carried Interest Percentage of all
Members of the LLC as it may be adjusted from time to time by the operating
agreement of the LLC.  This Section 5 shall terminate upon the occurrence of a
Final Liquidity Event under the LLC Operating Agreement.

     6.   Term.  This Agreement shall have a term of four (4) years, provided 
          ----
that Sections 9 and 10 shall survive such expiration in accordance with their
terms. 

     7.   Termination.
          ----------- 

          (a)  This Agreement may be terminated by the Company at any time for
Cause upon written notice to Executive, which notice shall specify the reason
for termination. Such notice shall be given at any time prior to termination in
the case of matters described in clauses (B) or (C), and shall be given not less
than 30 days prior to the date of termination, in the case of matters described
in clauses (A), (D) or (E), and in the case of matters described in clauses (A),
(D) or (E) shall be rescinded if the Executive cures any misconduct, negligent
act, breach or failure giving rise to such notice to the reasonable satisfaction
of the Board of Directors, including curing any damage suffered by the Company
as a result thereof. As used herein, "Cause" shall mean (A) willful misconduct
or gross negligence by Executive in respect of his material obligations under
this Agreement, (B) conviction of a felony involving moral turpitude, (C) theft
of Company property or other disloyal or dishonest conduct of the Executive that
materially 

                                       4
<PAGE>
 
harms the Company or its business or (in the case of dishonest conduct)
undermines the confidence of the Board in the Executive, (D) willful breach of
this Agreement, or (E) willful failure to observe Company policies or carry out
the directives of the Board of Directors that are not inconsistent with the
position of Executive as provided in Section 1 hereof.

          (b)  Executive may terminate this Agreement for Good Reason by giving
thirty (30) days prior written notice to the Company.  Good Reason shall exist
only if (i) Executive is removed or is not re-appointed as the Company's Chief
Executive Officer, except in connection with termination of this Agreement by
the Company for Cause or due to death or Disability (as defined below), (ii)
Executive is assigned duties, or authority is withdrawn from Executive,
inconsistent with Executive's authority pursuant to Section 1, without
Executive's express written consent, (iii) breach by the Company of any material
obligation of the Company under this Agreement or (iv) Hellman & Friedman (as
defined in the operating agreement of LLC) shall cease to beneficially own at
least 50% of the membership interests in LLC or, following dissolution of LLC,
at least 50% of the voting securities of the Company, and, in either such case,
another person or group (as defined in Section 13 of the Securities Exchange
Act) beneficially owns a greater percentage of such membership interests or
voting securities.

          (c)  Should the Executive terminate this Agreement for Good Reason, or
should the Company terminate this Agreement without Cause, then the Executive
shall be entitled to receive, for a period of one year, the salary and the
benefits provided for in Sections 3 and 4 hereof (provided, that any bonus under
Section 3(c) will be payable only with respect to that portion of the fiscal
year in which Executive's employment was terminated (or any prior fiscal year
for which bonus remains unpaid)); bonus for any partial fiscal year shall be
determined by multiplying the bonus Executive would have received had he
continued to work for the Company during the entire fiscal year by a fraction,
the numerator of which is the number of days in the fiscal year during which
Executive was employed by the Company, and the denominator of which is 365 (such
amount the "Pro Rata Bonus Amount").  If any such benefits cannot be legally
provided, or the provision thereof would disqualify any plan for favorable tax
treatment under the Internal Revenue Code, a financially equivalent substitute
shall be provided.  The Company shall have no obligation to Executive under this
Section 8(c) if Executive breaches the provisions of the letter agreement
referred to in Section 9.  This clause (c) shall not apply to a termination
under clause (d) below.

          (d)  This Agreement shall terminate automatically upon Executive's
death. This Agreement may be terminated by the Company upon written notice to
Executive, or by Executive upon written notice to the Company, upon Executive's
Disability. For purposes of this Agreement, "Disability" means the Executive's
suffering of a disability which shall have prevented him from performing his
obligations hereunder 

                                       5
<PAGE>
 
for a period of at least 120 consecutive days or 180 non-consecutive days in any
365 day period. In the event of termination of this Agreement due to Executive's
death or Disability, in addition to any salary due to Executive as of the date
of death or Disability and remaining unpaid, Executive shall be entitled to
receive, at such time as Executive would otherwise would have received such sum,
the Pro Rata Bonus Amount for the portion of the fiscal year in which
Executive's death or Disability occurred during which Executive was employed by
the Company.

          (e)  If the Company terminates this Agreement with Cause or if the
Executive terminates this Agreement without Good Reason, or if this Agreement is
terminated under clause (d) above, then the Executive shall, from the date of
such termination, no longer be entitled to any compensation under Sections 3 or
4 (other than, in the case of termination for Disability, disability benefits as
provided pursuant to Section 4 and, in the case of termination for death or
Disability, any bonus payable pursuant to clause (d) above).  Nothing in this
clause (e) shall effect Executive's rights under Company health and disability
plans in which Executive participates to the extent such plans provide for
benefits to be paid following the termination of employment.

          (f)  Termination of this Agreement shall not discharge any liability
existing at the date of termination.  Further, notwithholding any termination,
the provisions of Sections 9 and 10 shall survive in accordance with their
terms.

     8.   Effective Date.  This Agreement shall take effect as of July 1, 1996.
          --------------                                                       

     9.   Non-Competition and Confidentiality.  Executive shall execute and 
          -----------------------------------
deliver a letter agreement in the form of Exhibit A hereto.

     10.  Arbitration.  Any claim arising out of or relating to this Agreement
          -----------                                                         
(including disputes regarding the presence or absence of "Cause" or "Good
Reason" in the event of a termination), or otherwise arising out of or relating
to the Executive's employment by the Company, will be subject to arbitration in
San Francisco, California (if brought by Executive) or Boston, Massachusetts (if
brought by the Company), in accordance with the Federal Arbitration Act and the
rules of the American Arbitration Association relating to commercial disputes.
The prevailing party in any such arbitration shall be entitled to recover from
the other party its reasonable expenses incurred in connection with such
arbitration, including the reasonable fees and expenses of counsel.

     11.  Severability.  If any provision of this Agreement is determined to be
          ------------                                                         
invalid or unenforceable, it shall be adjusted rather than voided, to achieve
the intent of the parties to the extent possible, and the remainder of the
Agreement shall be enforced to the maximum extent possible.

                                       6
<PAGE>
 
     12.  Entire Agreement.  This Agreement constitutes the entire agreement 
          ----------------
between Executive and the Company with respect to the terms and conditions of
the employment of Executive by the Company, and supersedes all prior or
concurrent arrangements, discussions, agreements or understandings with respect
to your employment.

          -------------
California without regard to principles of conflicts of law.

reasonable out-of-pocket expenses incurred by Executive in negotiating,
executing and delivering this Agreement and the related agreements executed and
delivered in connection herewith (including the reasonable fees and expenses of
legal counsel), up to a maximum of $50,000.

     15.  Notice.  Any notice, or other written communication to be given 
          ------
pursuant to this Agreement for whatever reason shall be deemed duly given and

Dear Mr. Krakoff:

     You are to be employed by AHI Holding Corp. (the "Company" and, together
with Advanstar Holdings, Inc. and its subsidiaries "Advanstar").  In
consideration of your employment with the Company, you and the Company agree as
follows:

     1.   Non-Competition.  You agree that you will not, during the course of 
          ---------------
your employment with the Company or for the Non-Compete Period following the
termination of such employment, compete with Advanstar, as defined in paragraph
4 below.  As used herein "Non-Compete Period" means (a) if your employment is
terminated by the Company without Cause (as defined therein) or by you for Good
Reason (as defined therein), six months or (b) if your employment is terminated
for any other reason, one year.

     2.   Confidentiality.  You acknowledge that your association with 
          ---------------
Advanstar will bring you into close contact with many confidential affairs of
Advanstar, including information about costs, profits, markets, sales,
publications, key personnel, pricing policies, operational methods, other
business affairs, methods and other information not readily available to the
public, and plans for future development. In recognition of the foregoing, you
covenant and agree that you will keep confidential all material confidential to
Advanstar that is not otherwise in the public domain and that you will not
intentionally disclose any such information to anyone outside Advanstar or make
any use thereof for your own benefit or for any purpose other than the
advancement of the business of Advanstar at any time except with the prior
written consent of Advanstar as evidenced by a certified resolution of the Board
of Directors of the Company. For purposes of this Agreement, the following
information shall be deemed not to constitute confidential information of
Advanstar:

          (a)  Any information developed independently by you;
<PAGE>
 
          (b)  Information that was received by you from a third-party, which,
               to your knowledge, is not bound by an agreement of
               confidentiality with Advanstar; or

          (c)  Any information that is in the public domain or generally
               available to the public.

     3.   No Solicitation of Employees.  You covenant that during the 
          ----------------------------
Non-Compete Period you will not, and no person, corporation, partnership, or
other entity over which you exercise control (whether as an officer, director,
sole proprietor, holder, debt or equity securities, consultant, partner, or
otherwise) will, directly or indirectly (a) enter into any written or oral
agreement or understanding relating to the services of any person who is then
employed by Advanstar or, in the case of any employee other than secretaries,
clerks and similar employees fulfilling merely clerical functions, who has been
so employed within the preceding six months, or (b) solicit, or bid against
Advanstar in an attempt to be awarded, any trade show or exposition business, or
any publishing contract, from any party sponsoring or arranging any trade show
or exposition, or publishing or sponsoring any publication, in either case with
which Advanstar then has such a relationship or contract.

     4.   Certain Definitions.  For purposes of this Letter Agreement, 
          -------------------
competition with Advanstar shall include carrying on any business that is
competitive with the business of Advanstar, in the United States or in any other
country in which Advanstar conducts business as of the termination of your
employment. For purposes of this Letter Agreement, (a) the business of Advanstar
will be deemed to include (without limitation) the organization of trade shows
and expositions of the type and with respect to the industries held by Advanstar
as of the termination of your employment (it being understood that industry
shall be analogized to the categories of the category system of the Standard
Rate Data Service) and the publication (including electronic publication) of
trade journals and other magazines aimed at the particular businesses,
industries or professions (as defined by category according to the category
system of the Standard Rate Data Service) at which Advanstar's operations are
aimed, and (b) each of the following activities (without limitation) will be
deemed to constitute to carrying on business: to engage in, work with, have
interest in, advise, lend money to, guarantee the debts or obligations of, or
permit one's name or any part thereof to be used in connection with, an
enterprise or endeavor either individually, in partnership, or in conjunction
with any person, firm, association, company, or corporation, whether as
principal, agent, shareholder (other than holding of less than 1% of the voting
securities of any public company or 5% of the voting securities of any private
company), employee, director, consultant, or in any other capacity or manner
whatsoever.
<PAGE>
 
     5.   Severability.  The scope and effect of the terms and provisions 
          ------------
contained in this Letter Agreement (including the noncompetition covenant
contained in Section 1) will be as broad in time (but not beyond the time
periods specified herein), geography, and all other respects as is permitted by
applicable law. If arbitrators, a court, or another body of competent
jurisdiction determine that any term or provision of this Agreement is excessive
in scope, then if possible such term or provision will be adjusted (rather than
voided) in accordance with the purpose stated in the preceding sentence and with
applicable law, but in such a manner as to minimize the change in the provision.
If such term or provision cannot be so adjusted, then it will be struck. All
other terms and provisions of this Letter Agreement will be deemed valid and
enforceable to the full extent possible.

     6.   Remedies.  If any of the covenants or agreements in Sections 1, 2 or 
          --------
3 are violated or threatened to be violated, you agree and acknowledge that such
violation or threatened violation will cause irreparable injury to Advanstar,
and that the remedy at law of Advanstar for any such violation or threatened
violation will be inadequate and that Advanstar will be entitled to obtain any
injunction prohibiting a continuance or occurrence of such violations or
threatened violations in addition to (not in limitation of) any other rights or
remedies available at law or in equity.  Your services hereunder are of a
special, unique, unusual, extraordinary character which gives them peculiar
value, the loss of which cannot be reasonably or adequately computed in damages.

     The provisions of this Letter Agreement will be binding upon and inure to
the benefit of our respective heirs, executives, administrators, successors and
assigns.  This Letter Agreement will be governed by and construed in accordance
with the laws of the Commonwealth of Massachusetts.

                                        Very truly yours,

                                        AHI HOLDING CORP.

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

     THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into as of
July 1, 1996 by and between AHI HOLDING CORP., a Delaware corporation (the
"Company") and James Alic ("Executive").

     WHEREAS, the Company has acquired, pursuant to a Merger Agreement dated as
of April 12, 1996, and currently operates certain trade exposition and
publishing businesses; and

     WHEREAS, the Company wishes to employ Executive and Executive is prepared
to serve in those capacities required by the Company.

     NOW, THEREFORE, the parties agree as follows:

     1.  Position and Authority. The Company agrees to employ the Executive, and
         ---------------------- 
the Executive accepts such employment and agrees to serve the Company as Vice
Chairman of the Company and its respective Subsidiaries, for the compensation
and benefits detailed in Sections 3 and 4 hereof. It is understood that the
Executive will report to the Chief Executive Officer of the Company. A
"Subsidiary" shall be any company in which the Company beneficially owns more
than 50% of the voting power of such company's outstanding voting securities.

     2.  Duties. Executive shall devote substantially all of his business time
         ------ 
(subject to four weeks of vacation, or such greater amount as is authorized by
the Board of Directors) to the affairs of the Company during the employment
term, except as may be consented to by the Board of Directors. Notwithstanding
the foregoing, to the extent that it does not materially interfere with the
performance of his duties, Executive may devote such business time as is
reasonably necessary to his duties as a director of not more than two business
corporations not affiliated with the Company, and Executive may devote business
time to any charitable or not-for-profit activities. Executive shall perform
such duties and responsibilities as the Board of Directors or Chief Executive
Officer of the Company may from time to time reasonably determine, provided that
such duties and responsibilities are consistent with Executive's position and do
not diminish Executive's authority as set forth in Section 1 hereof. Executive
will not be required to relocate his permanent residence.

     3.  Base Compensation and Bonus.
         ---------------------------

          (a) Base Composition.  Executive will be compensated at a base salary
              ----------------                                                 
rate of $300,000 per year (or such higher rate as may be set from time to time
by the Board of Directors in its discretion) during the employment term.  Base
compensation will be paid in installments on the same schedule as the Company's
Subsidiaries generally 
<PAGE>
 
pay their employees. All compensation and benefits will be subject to reduction
by all federal, state, local and other withholdings and similar taxes and
payments required by applicable law.

          (b)  Bonus for the Fiscal Year Ended December 31, 1996. The Executive
               -------------------------------------------------
shall receive a bonus of $75,000 for the fiscal year ended December 31, 1996.

          (c)  Bonus for Subsequent Fiscal Years.  In addition to Executive's
               ---------------------------------                             
base compensation, Executive will receive bonus compensation based on the
relationship between the Company's actual earnings before interest, taxes,
depreciation and amortization ("EBITDA") for each fiscal year starting with the
fiscal year ending December 31, 1997 (determined based on the Company's audited
financial statements for such fiscal year) and the EBITDA set for such year in
the Company "Adjusted Business Plan" (as defined below) as follows:

      Actual EBITDA          Bonus
      as a Percentage        (as a Percentage of  Base Salary)
                              -------------------------------
      of Plan 
      --------------- 

      Less than 80%           No bonus
      100%                    50% of Base Salary
      120%                    100% of Base Salary


If actual EBITDA as a percentage of the Company's Adjusted Business Plan falls
between 80% and 120%, the amount of bonus shall be pro rated on a straight-line
basis.  In no case shall bonus payable under this Section 3(c) exceed 100% of
Base Salary unless agreed to by the Board of Directors in its absolute
discretion.

     The "Adjusted Business Plan" shall be the Company's business plan for the
fiscal year in question as approved by the Board of Directors with the consent
of the Chief Executive Officer of the Company, appropriately adjusted for
acquisitions or dispositions during the year as determined by the Board of
Directors in good faith.  If the Board and the Chief Executive Officer do not
adopt a mutually satisfactory business plan prior to the beginning of any fiscal
year, the business plan for purposes of this Section 3(c) shall be the business
plan submitted to Chemical Bank and dated May, 1996, subject to adjustment as
provided above for acquisitions and dispositions occurring after May 31, 1996.

     Any bonus payable under this Section 3(c) shall be paid not later than 60
days after the applicable fiscal year end.
<PAGE>
 
     4.   Benefits.
          -------- 

          (a)  During Executive's employment by the Company, Executive will
receive the same (or substantially similar) employee benefits to those provided
by the Company or its Subsidiaries to other members of senior management from
time to time.

          (b)  During and after the employment term the Company agrees that if
Executive is made a party, or compelled to testify or otherwise participate in,
any action, suit or proceeding (a "Proceeding"), by reason of the fact that he
is or was a director or officer of the Company or any of its Subsidiaries,
Executive shall be indemnified by the Company as provided in Section 145 of the
Delaware General Corporation Law or (but not to any lesser extent) as authorized
by the Company's certificate of incorporation or bylaws or resolutions of the
company's Board of Directors against all cost, expense, liability, damage and
loss reasonably incurred or suffered by Executive in connection therewith, and
such indemnification shall continue as to Executive even if he has ceased to be
a director or officer of the Company or Subsidiary for the period of any
applicable statute of limitations or, if longer, for the period in which any
such Proceeding which commenced within the period of any such statute of
limitations is pending.  The Company shall advance to Executive all reasonable
costs and expenses incurred by him in connection with a Proceeding within
20 days after receipt by the Company of a written request for such advance.
Such request shall include an itemized list of the costs and expenses and an
undertaking by Executive to repay the amount of such advance if it shall
ultimately be determined, in a final judgment for which the time to appeal has
expired, that, pursuant to applicable law, he is not entitled to be indemnified
against such costs and expenses.

          (c)  The Company will reimburse Executive for his reasonable and
customary business expenses, including travel, accommodations and meals.  Such
reimbursement shall include the reasonable cost of travel to and from Boston,
Cleveland and other Company offices and accommodations and meals when outside of
his residence location.

     5.   [Reserved]

     6.   Term.  This Agreement shall have a term of four (4) years, provided
          ----                                                               
that Sections 9 and 10 shall survive such expiration in accordance with their
terms.

     7.   Termination.
          ----------- 

          (a) This Agreement may be terminated by the Company at any time for
Cause upon written notice to Executive, which notice shall specify the reason
for termination.  Such notice shall be given at any time prior to termination in
the case of matters described in clauses (B) or (C), and shall be given not less
than 30 days prior to 
<PAGE>
 
the date of termination, in the case of matters described in clauses (A), (D) or
(E), and in the case of matters described in clauses (A), (D) or (E) shall be
rescinded if the Executive cures any misconduct, negligent act, breach or
failure giving rise to such notice to the reasonable satisfaction of the Board
of Directors, including curing any damage suffered by the Company as a result
thereof. As used herein, "Cause" shall mean (A) willful misconduct or gross
negligence by Executive in respect of his material obligations under this
Agreement, (B) conviction of a felony involving moral turpitude, (C) theft of
Company property or other disloyal or dishonest conduct of the Executive that
materially harms the Company or its business or (in the case of dishonest
conduct) undermines the confidence of the Board in the Executive, (D) willful
breach of this Agreement, or (E) willful failure to observe Company policies or
carry out the directives of the Board of Directors that are not inconsistent
with the position of Executive as provided in Section 1 hereof.

          (b)  Executive may terminate this Agreement for Good Reason by giving
thirty (30) days prior written notice to the Company.  Good Reason shall exist
only if (i) Executive is removed or is not re-appointed as the Company's Vice
Chairman, except in connection with termination of this Agreement by the Company
for Cause or due to death or Disability (as defined below), (ii) Executive is
assigned duties, or authority is withdrawn from Executive, inconsistent with
Executive's authority pursuant to Section 1, without Executive's express written
consent, (iii) breach by the Company of any material obligation of the Company
under this Agreement (iv) Hellman & Friedman (as defined in the operating
agreement of LLC) shall cease to beneficially own at least 50% of the membership
interests in LLC or, following dissolution of LLC, at least 50% of the voting
securities of the Company and, in either such case, another person or group (as
defined in Section 13 of the Securities Exchange Act) beneficially owns a
greater percentage of such membership interests or voting securities or (v)
Robert Krakoff ceases to be the Chief Executive Officer of the Company and
Executive is not appointed Chief Executive Officer of the Company.

          (c)  Should the Executive terminate this Agreement for Good Reason, or
should the Company terminate this Agreement without Cause, then the Executive
shall be entitled to receive, for a period of one year, the salary and the
benefits provided for in Sections 3 and 4 hereof (provided, that any bonus under
Section 3(c) will be payable only with respect to that portion of the fiscal
year in which Executive's employment was terminated (or any prior fiscal year
for which bonus remains unpaid)); bonus for any partial fiscal year shall be
determined by multiplying the bonus Executive would have received had he
continued to work for the Company during the entire fiscal year by a fraction,
the numerator of which is the number of days in the fiscal year during which
Executive was employed by the Company, and the denominator of which is 365 (such
amount the "Pro Rata Bonus Amount").  If any such benefits cannot be legally
provided, or the provision thereof would disqualify any plan for favorable tax
treatment under the 
<PAGE>
 
Internal Revenue Code, a financially equivalent substitute shall be provided.
The Company shall have no obligation to Executive under this Section 8(c) if
Executive breaches the provisions of the letter agreement referred to in Section
9. This clause (c) shall not apply to a termination under clause (d) below.

          (d)  This Agreement shall terminate automatically upon Executive's
death.  This Agreement may be terminated by the Company upon written notice to
Executive, or by Executive upon written notice to the Company, upon Executive's
Disability.  For purposes of this Agreement, "Disability" means the Executive's
suffering of a disability which shall have prevented him from performing his
obligations hereunder for a period of at least 120 consecutive days or 180 non-
consecutive days in any 365 day period.  In the event of termination of this
Agreement due to Executive's death or Disability, in addition to any salary due
to Executive as of the date of death or Disability and remaining unpaid,
Executive shall be entitled to receive, at such time as Executive would
otherwise would have received such sum, the Pro Rata Bonus Amount for the
portion of the fiscal year in which Executive's death or Disability occurred
during which Executive was employed by the Company.

          (e)  If the Company terminates this Agreement with Cause or if the
Executive terminates this Agreement without Good Reason, or if this Agreement is
terminated under clause (d) above, then the Executive shall, from the date of
such termination, no longer be entitled to any compensation under Sections 3 or
4 (other than, in the case of termination for Disability, disability benefits as
provided pursuant to Section 4 and, in the case of termination for death or
Disability, any bonus payable pursuant to clause (d) above.).  Nothing in this
clause (e) shall affect Executive's rights under Company health and disability
plans in which Executive participates to the extent such plans provide for
benefits to be paid following the termination of employment.

          (f)  Termination of this Agreement shall not discharge any liability
existing at the date of termination.  Further, notwithholding any termination,
the provisions of Sections 9 and 10 shall survive in accordance with their
terms.

     8.   Effective Date.  This Agreement shall take effect as of July 1, 1996.
          --------------                                                       
     9.   Non-Competition and Confidentiality.  Executive shall execute and
          -----------------------------------                              
deliver a letter agreement in the form of Exhibit A hereto.

     10.  Arbitration.  Any claim arising out of or relating to this Agreement
          -----------                                                         
(including disputes regarding the presence or absence of "Cause" or "Good
Reason" in the event of a termination), or otherwise arising out of or relating
to the Executive's employment by the Company, will be subject to arbitration in
San Francisco, California (if brought by Executive) or Boston, Massachusetts (if
brought by the Company), in 
<PAGE>
 
accordance with the Federal Arbitration Act and the rules of the American
Arbitration Association relating to commercial disputes. The prevailing party in
any such arbitration shall be entitled to recover from the other party its
reasonable expenses incurred in connection with such arbitration, including the
reasonable fees and expenses of counsel.

     11.  Severability.  If any provision of this Agreement is determined to be
          ------------                                                         
invalid or unenforceable, it shall be adjusted rather than voided, to achieve
the intent of the parties to the extent possible, and the remainder of the
Agreement shall be enforced to the maximum extent possible.

     12.  Entire Agreement.  This Agreement constitutes the entire agreement
          ----------------                                                  
between Executive and the Company with respect to the terms and conditions of
the employment of Executive by the Company, and supersedes all prior or
concurrent arrangements, discussions, agreements or understandings with respect
to your employment.

     13.  Governing Law.  This Agreement shall be governed by the laws of
          -------------                                                  
California without regard to principles of conflicts of law.

     14.  Expenses.  The Company shall pay, or reimburse Executive for, the
          --------                                                         
reasonable out-of-pocket expenses incurred by Executive in negotiating,
executing and delivering this Agreement and the related agreements executed and
delivered in connection herewith (including the reasonable fees and expenses of
legal counsel), up to a maximum of $50,000 less any amount (which may be up to
                                           ----                               
$50,000) that the Company pays to Robert L. Krakoff as reimbursement for his
expenses under Section 14 of his employment agreement with the Company.

     15.  Notice.  Any notice, or other written communication to be given
          ------

Dear Mr. Alic:

     You are to be employed by AHI Holding Corp. (the "Company" and, together
with Advanstar Holdings, Inc. and its subsidiaries "Advanstar").  In
consideration of your employment with the Company, you and the Company agree as
follows:

     1.   Non-Competition.  You agree that you will not, during the course of
          ---------------                                                    
your employment with the Company or for the Non-Compete Period following the
termination of such employment, compete with Advanstar, as defined in paragraph
4 below.  As used herein "Non-Compete Period" means (a) if your employment is
terminated by the Company without Cause (as defined therein) or by you for Good
Reason (as defined therein), six months or (b) if your employment is terminated
for any other reason, one year.

     2.   Confidentiality.  You acknowledge that your association with Advanstar
          ---------------                                                       
will bring you into close contact with many confidential affairs of Advanstar,
including information about costs, profits, markets, sales, publications, key
personnel, pricing policies, operational methods, other business affairs,
methods and other information not readily available to the public, and plans for
future development.  In recognition of the foregoing, you covenant and agree
that you will keep confidential all material confidential to Advanstar that is
not otherwise in the public domain and that you will not intentionally disclose
any such information to anyone outside Advanstar or make any use thereof for
your own benefit or for any purpose other than the advancement of the business
of Advanstar at any time except with the prior written consent of Advanstar as
evidenced by a certified resolution of the Board of Directors of the Company.
For purposes of this Agreement, the following information shall be deemed not to
constitute confidential information of Advanstar:

          (a)  Any information developed independently by you;
<PAGE>
 
          (b)  Information that was received by you from a third-party, which,
               to your knowledge, is not bound by an agreement of
               confidentiality with Advanstar; or

          (c)  Any information that is in the public domain or generally
               available to the public.

     3.   No Solicitation of Employees.  You covenant that during the Non-
          ----------------------------                                   
Compete Period you will not, and no person, corporation, partnership, or other
entity over which you exercise control (whether as an officer, director, sole
proprietor, holder, debt or equity securities, consultant, partner, or
otherwise) will, directly or indirectly (a) enter into any written or oral
agreement or understanding relating to the services of any person who is then
employed by Advanstar or, in the case of any employee other than secretaries,
clerks and similar employees fulfilling merely clerical functions, who has been
so employed within the preceding six months, or (b) solicit, or bid against
Advanstar in an attempt to be awarded, any trade show or exposition business, or
any publishing contract, from any party sponsoring or arranging any trade show
or exposition, or publishing or sponsoring any publication, in either case with
which Advanstar then has such a relationship or contract.

     4.   Certain Definitions.  For purposes of this Letter Agreement,
          -------------------                                         
competition with Advanstar shall include carrying on any business that is
competitive with the business of Advanstar, in the United States or in any other
country in which Advanstar conducts business as of the termination of your
employment.  For purposes of this Letter Agreement, (a) the business of
Advanstar will be deemed to include (without limitation) the organization of
trade shows and expositions of the type and with respect to the industries held
by Advanstar as of the termination of your employment (it being understood that
industry shall be analogized to the categories of the category system of the
Standard Rate Data Service) and the publication (including electronic
publication) of trade journals and other magazines aimed at the particular
businesses, industries or professions (as defined by category according to the
category system of the Standard Rate Data Service) at which Advanstar's
operations are aimed, and (b) each of the following activities (without
limitation) will be deemed to constitute to carrying on business: to engage in,
work with, have interest in, advise, lend money to, guarantee the debts or
obligations of, or permit one's name or any part thereof to be used in
connection with, an enterprise or endeavor either individually, in partnership,
or in conjunction with any person, firm, association, company, or corporation,
whether as principal, agent, shareholder (other than holding of less than 1% of
the voting securities of any public company or 5% of the voting securities of
any private company), employee, director, consultant, or in any other capacity
or manner whatsoever.
<PAGE>
 
     5.   Severability.  The scope and effect of the terms and provisions
          ------------                                                   
contained in this Letter Agreement (including the noncompetition covenant
contained in Section 1) will be as broad in time (but not beyond the time
periods specified herein), geography, and all other respects as is permitted by
applicable law.  If arbitrators, a court, or another body of competent
jurisdiction determine that any term or provision of this Agreement is excessive
in scope, then if possible such term or provision will be adjusted (rather than
voided) in accordance with the purpose stated in the preceding sentence and with
applicable law, but in such a manner as to minimize the change in the provision.
If such term or provision cannot be so adjusted, then it will be struck.  All
other terms and provisions of this Letter Agreement will be deemed valid and
enforceable to the full extent possible.

     6.   Remedies.  If any of the covenants or agreements in Sections 1, 2 or 3
          --------                                                              
are violated or threatened to be violated, you agree and acknowledge that such
violation or threatened violation will cause irreparable injury to Advanstar,
and that the remedy at law of Advanstar for any such violation or threatened
violation will be inadequate and that Advanstar will be entitled to obtain any
injunction prohibiting a continuance or occurrence of such violations or
threatened violations in addition to (not in limitation of) any other rights or

                               AHI HOLDING CORP.


                             1996 STOCK OPTION PLAN
                             ----------------------


   1.  PURPOSE.  The purpose of this 1996 Stock Option Plan (the "Plan") is to
       -------                                                                
encourage employees of AHI Holding Corp. (the "Company") and of any present or
future parent or subsidiary of the Company (collectively, "Related
Corporations"), and other individuals who render services to the Company or a
Related Corporation, by providing opportunities to purchase stock in the Company
pursuant to options granted hereunder ("Non-Qualified Options").  Non-Qualified
Options are referred to hereafter individually as an "Option" and collectively
as "Options."  As used herein, the terms "parent" and "subsidiary" mean "parent
corporation" and "subsidiary corporation," respectively, as those terms are
defined in Section 424 of the Internal Revenue Code of 1986, as amended (the
"Code").


   2.  ADMINISTRATION OF THE PLAN.
       -------------------------- 

       A.   BOARD OR COMMITTEE ADMINISTRATION.  The Plan shall be administered
            ---------------------------------                                 
   by the Board of Directors of the Company (the "Board") or, by a committee
   appointed by the Board (the "Committee").  Hereinafter, all references in
   this Plan to the "Committee" shall mean the Board if no Committee has been
   appointed.  Subject to ratification of the grant or authorization of each
   Option by the Board (if so required by applicable state law), and subject to
   the terms of the Plan, the Committee shall have the authority to (i)
   determine to whom Options may be granted; (ii) determine the time or times at
   which Options shall be granted; (iii) determine the exercise price of shares
   subject to each Option, which price shall not be less than the minimum price
   specified in paragraph 6; (iv) determine (subject to paragraph 7) the time or
   times when each Option shall become exercisable and the duration of the
   exercise period; (v) extend the period during which outstanding Options may
   be exercised; (vi) determine whether restrictions such as repurchase options
   are to be imposed on shares subject to Options and the nature of such
   restrictions, if any; and (vii) interpret the Plan and prescribe and rescind
   rules and regulations relating to it. The Committee shall take whatever
   actions it deems necessary, under Section 422 of the Code and the regulations
   promulgated thereunder, to ensure that Options granted hereunder are not
   treated as "incentive stock options" ("ISOs").  The interpretation and
   construction by the Committee of any provisions of the Plan or of any Option
   granted under it shall be final unless otherwise determined by the Board.
   The Committee may from time to time adopt such rules and regulations for
   carrying out the Plan as it may deem advisable.  No member of the Board or
   the Committee shall be liable for any action or determination made in good
   faith with respect to the Plan or any Option granted under it.

                                      -2-



       B.  COMMITTEE ACTIONS.  The Committee may select one of its members as
           -----------------                                                 
   its chairman, and shall hold meetings at such time and places as it may
   determine.  A majority of the Committee shall constitute a quorum and acts by
   a majority of the members of the Committee at a meeting at which a quorum is
   present, or acts reduced to or approved in writing by a majority of the
   members of the Committee (if consistent with applicable state law), shall
   constitute the valid acts of the Committee.  From time to time the Board may
   increase the size of the Committee and appoint additional members thereof,
   remove members (with or without cause) and appoint new members in
   substitution therefor, fill vacancies however caused, or remove all members
   of the Committee and thereafter directly administer the Plan.

       C.  GRANT OF OPTIONS TO BOARD MEMBERS.  All grants of Options to members
           ---------------------------------                                   
   of the Board shall in all respects be made in accordance with the provisions
   of this Plan applicable to other eligible persons.  Consistent with the
   provisions of the first sentence of paragraph 2(A) above, members of the
   Board who either (i) are eligible to receive grants of Options pursuant to
   the Plan or (ii) have been granted Options may vote on any matters affecting
   the administration of the Plan or the grant of any Options pursuant to the
   Plan, except that no such member shall act upon the granting to himself or
   herself of Options, but any such member may be counted in determining the
   existence of a quorum at any meeting of the Board during which action is
   taken with respect to the granting to such member of Options.


       D.  PERFORMANCE-BASED COMPENSATION.  The Board, in its discretion, may
           ------------------------------                                    
   take such action as may be necessary to ensure that Options granted under the
   Plan qualify as "qualified performance-based compensation" within the meaning
   of Section 162(m) of the Code and applicable regulations promulgated
   thereunder ("Performance-Based Compensation").  Such action may include, in
   the Board's discretion, some or all of the following (i) if the Board
   determines that Options granted under the Plan generally shall constitute
   Performance-Based Compensation, the Plan shall be administered, to the extent
   required for such Options to constitute Performance-Based Compensation, by a
   Committee consisting solely of two or more "outside directors" (as defined in
   applicable regulations promulgated under Section 162(m) of the Code), (ii) if
   any Options with an exercise price less than the fair market value per share
   of Common Stock are granted under the Plan and the Board determines that such
   Options should constitute Performance-Based Compensation, such options shall
   be made exercisable only upon the attainment of a pre-established, objective
   performance goal established by the Committee, and such grant shall be
   submitted for, and shall be contingent upon shareholder approval and (iii)
   Options granted under the Plan may be subject to such other terms and
   conditions as are necessary for compensation recognized in connection with
   the exercise or disposition of such stock option or the disposition of Common
   Stock acquired pursuant to such stock option, to constitute Performance-Based
   Compensation.

     3.   ELIGIBLE EMPLOYEES AND OTHERS. Options may be granted to any employee,
          -----------------------------
officer or director (whether or not also an employee) or consultant of the
Company or any Related Corporation. The granting of any Option to any individual
or entity shall neither entitle that individual or entity to, nor disqualify
such individual or entity from, participation in any other grant of Options.

     4.   STOCK. The stock subject to Options shall be authorized but unissued
          -----
shares of Common Stock of the Company, par value $ 0.01 per share (the "Common
Stock"), or shares of Common Stock reacquired by the Company in any manner. The
aggregate number of shares which may be issued pursuant to the Plan is 7,452
(without giving effect to the 100-for-1 split of the Common Stock contemplated
for the first half of 1997), subject to adjustment as provided in paragraph 13.
If any Option granted under the Plan shall expire or terminate for any reason
without having been exercised in full or shall cease for any reason to be
exercisable in whole or in part or shall be repurchased by the Company, the
shares subject to such Option shall again be available for grants of Options
under the Plan.

     5.   GRANTING OF OPTIONS.  Options may be granted under the Plan at any
          -------------------
time on or after November 15, 1996 and prior to November 15, 2006. The date of
grant of an Option under the Plan will be the date specified by the Committee at
the time it grants the Option; provided, however, that such date shall not be
prior to the date on which the Committee acts to approve the grant.

     6.   MINIMUM OPTION PRICE.
          -------------------- 

          A.   PRICE FOR OPTIONS.  Subject to Paragraph 2(D) (relating to
               -----------------                                         
     compliance with Section 162(m) of the Code), the exercise price per share
     of each Option granted under the Plan shall be the fair market value of the
     Common Stock of the Company on the date of grant, unless otherwise
     specified in the agreement relating to the grant of such Option; provided
     that in no event shall such exercise price be less than the minimum legal
     consideration required therefor under the laws of any jurisdiction in which
     the Company or its successors in interest may be organized.

          B.   RESERVED.
               -------- 

          C.   RESERVED.
               -------- 

          D.   DETERMINATION OF FAIR MARKET VALUE.  If, at the time an Option is
               ----------------------------------                               
     granted under the Plan, the Company's Common Stock is publicly traded,
     "fair market value" shall be determined as of the date of grant or, if the
     prices or quotes discussed in this sentence are unavailable for such date,
     the last business day for which such prices or quotes are available prior
     to the date of grant and shall mean (i) the average (on that date) of the
     high and low prices of the Common Stock on the principal national
     securities exchange on which the Common Stock is traded, if the Common
     Stock is then

<PAGE>
 
                                      -4-

   traded on a national securities exchange; or (ii) the last reported sale
   price (on that date) of the Common Stock on the Nasdaq National Market, if
   the Common Stock is not then traded on a national securities exchange; or
   (iii) the closing bid price (or average of bid prices) last quoted (on that
   date) by an established quotation service for over-the-counter securities, if
   the Common Stock is not reported on the Nasdaq National Market. If the Common
   Stock is not publicly traded at the time an Option is granted under the Plan,
   "fair market value" shall be deemed to be the fair value of the Common Stock
   as determined by the Committee after taking into consideration all factors
   which it deems appropriate, including, without limitation, recent sale and
   offer prices of the Common Stock in private transactions negotiated at arm's
   length.

   7.  OPTION DURATION.  Subject to earlier termination as provided in
       ---------------                                                
paragraphs 9 and 10 or in the agreement relating to such Option, each Option
shall expire on the date specified by the Committee, but not more than ten years
from the date of grant.

   8.  EXERCISE OF OPTION.  Subject to the provisions of paragraphs 9 through
       ------------------                                                    
12, each Option granted under the Plan shall be exercisable as follows:

       A.   VESTING.  The Option shall either be fully exercisable on the date
            -------                                                           
   of grant or shall become exercisable thereafter in such installments as the
   Committee may specify.

       B.   FULL VESTING OF INSTALLMENTS.  Once an installment becomes
            ----------------------------                              
   exercisable it shall remain exercisable until expiration or termination of
   the Option, unless otherwise specified by the Committee.

       C.   PARTIAL EXERCISE.  Each Option or installment may be exercised at
            ----------------                                                 
   any time or from time to time, in whole or in part, for up to the total
   number of shares with respect to which it is then exercisable.

       D.   ACCELERATION OF VESTING.  The Committee shall have the right to
            -----------------------                                        
   accelerate the date on which any installment of any Option becomes
   exercisable.

   9.  TERMINATION OF EMPLOYMENT.  The termination of employment of an optionee
       -------------------------                                               
shall cause such optionee's Options to terminate immediately unless otherwise
specified in the agreement relating to the grant of such Options.  Nothing in
the Plan shall be deemed to give any optionee the right to be retained in
employment or other service by the Company or any Related Corporation for any
period of time. For purposes of this paragraph 9, employment shall be considered
as continuing uninterrupted during any bona fide leave of absence (such as those
attributable to illness, military obligations or governmental service) provided
that the period of such leave does not exceed 90 days or, if longer, any period
during which such optionee's right to reemployment is guaranteed by statute or
by contract.  A bona fide leave of absence with the written approval of the
Committee shall not be considered an interruption of employment under this
paragraph 9, 
<PAGE>
 
                                      -5-

provided that such written approval contractually obligates the Company or any
Related Corporation to continue the employment of the optionee after the
approved period of absence.

     10.  DEATH; DISABILITY.
          ----------------- 

          A.   DEATH. If an optionee ceases to be employed by the Company and
               -----
     all Related Corporations by reason of his or her death, any Option owned by
     such optionee may be exercised, to the extent otherwise exercisable on the
     date of death, by the estate, personal representative or beneficiary who
     has acquired the Option by will or by the laws of descent and distribution,
     until the earlier of (i) the specified expiration date of the Option or
     (ii) 365 days from the date of the optionee's death.

          B.   DISABILITY. If an optionee ceases to be employed by the Company
               ----------
     and all Related Corporations by reason of his or her disability, such
     optionee shall have the right to exercise any Option held by him or her on
     the date of termination of employment, to the extent of the number of
     shares with respect to which he or she could have exercised it on that
     date, until the earlier of (i) the specified expiration date of such Option
     or (ii) 365 days from the date of the termination of the optionee's
     employment. For the purposes of the Plan, the term "disability" shall mean
     "permanent and total disability" as defined in Section 22(e)(3) of the Code
     or any successor statute.


     11.  ASSIGNABILITY.  Options shall not be transferable except to the extent
          -------------                                                         
set forth in the agreement relating thereto.

     12.  TERMS AND CONDITIONS OF OPTIONS.  Options shall be evidenced by
          -------------------------------                                
instruments (which need not be identical) in such forms as the Committee may
from time to time approve.  Such instruments shall conform to the terms and
conditions set forth in paragraphs 6 through 11 hereof and may contain such
other provisions as the Committee deems advisable which are not inconsistent
with the Plan, including termination and cancellation provisions and
restrictions applicable to shares of Common Stock issuable upon exercise of
Options. The Committee may from time to time confer authority and responsibility
on one or more of its own members and/or one or more officers of the Company to
execute and deliver such instruments.  The proper officers of the Company are
authorized and directed to take any and all action necessary or advisable from
time to time to carry out the terms of such instruments.

     13.  ADJUSTMENTS.  Upon the occurrence of any of the following events, an
          -----------                                                         
optionee's rights with respect to Options granted to such optionee hereunder
shall be adjusted as hereinafter provided, unless otherwise specifically
provided in the written agreement between the optionee and the Company relating
to such Option:

            A.  STOCK DIVIDENDS AND STOCK SPLITS. If the shares of Common
                --------------------------------                         
   Stock shall be subdivided or combined into a greater or smaller number of
   shares 


<PAGE>
 
                                      -6-

   (including the 100-for-1 split of the Common Stock contemplated for the first
   half of 1997) or if the Company shall issue any shares of Common Stock as a
   stock dividend on its outstanding Common Stock, the number of shares of
   Common Stock deliverable upon the exercise of Options shall be appropriately
   increased or decreased proportionately, and appropriate adjustments shall be
   made in the purchase price per share to reflect such subdivision, combination
   or stock dividend.


          B.  CONSOLIDATIONS OR MERGERS.  If the Company is to be consolidated
              -------------------------                                       
   with or acquired by another entity in a merger or other reorganization in
   which the holders of the outstanding voting stock of the Company immediately
   preceding the consummation of such event, shall, immediately following such
   event, hold, as a group, less than a majority of the voting securities of the
   surviving or successor entity, or in the event of a sale of all or
   substantially all of the Company's assets or otherwise (each, an
   "Acquisition"), the Committee or, if in the absence of action by the
   Committee, the board of directors of any entity assuming the obligations of
   the Company hereunder (the "Successor Board"), shall, as to outstanding
   Options, either (i) make appropriate provision for the continuation of such
   Options by substituting on an equitable basis for the shares then subject to
   such Options either (a) the consideration payable with respect to the
   outstanding shares of Common Stock in connection with the Acquisition, (b)
   shares of stock of the surviving or successor corporation or (c) such other
   securities as the Successor Board deems appropriate, the fair market value of
   which shall not materially exceed the fair market value of the shares of
   Common Stock subject to such Options immediately preceding the Acquisition;
   or (ii) upon written notice to the optionees, provide that all Options must
   be exercised, to the extent then exercisable or to be exercisable as a result
   of the Acquisition, within a specified number of days of the date of such
   notice, at the end of which period the Options shall terminate; or (iii)
   terminate all Options in exchange for a cash payment equal to the excess of
   the fair market value of the shares subject to such Options (to the extent
   then exercisable or to be exercisable as a result of the Acquisition) over
   the exercise price thereof.


          C.  RECAPITALIZATION OR REORGANIZATION.  In the event of a
              ----------------------------------                    
   recapitalization or reorganization of the Company (other than a transaction
   described in subparagraph B above) pursuant to which securities of the
   Company or of another corporation are issued with respect to the outstanding
   shares of Common Stock, an optionee upon exercising an Option shall be
   entitled to receive for the purchase price paid upon such exercise the
   securities he or she would have received if he or she had exercised such
   Option prior to such recapitalization or reorganization.

          D.  RESERVED.
              -------- 

          E.  DISSOLUTION OR LIQUIDATION.  In the event of the proposed
              --------------------------                               
   dissolution or liquidation of the Company, each Option will terminate
   immediately prior to the consummation of such proposed action or at such
   other time and subject to such other conditions as shall be determined by the
   Committee.

                                      -7-


       F.   ISSUANCES OF SECURITIES.  Except as expressly provided herein, no
            -----------------------                                          
   issuance by the Company of shares of stock of any class, or securities
   convertible into shares of stock of any class, shall affect, and no
   adjustment by reason thereof shall be made with respect to, the number or
   price of shares subject to Options.  No adjustments shall be made for
   dividends paid in cash or in property other than securities of the Company.

       G.   FRACTIONAL SHARES.  No fractional shares shall be issued under the
            -----------------                                                 
   Plan and the optionee shall receive from the Company cash in lieu of such
   fractional shares.

       H.   ADJUSTMENTS.  Upon the happening of any of the events described in
            -----------                                                       
   subparagraphs A, B or C above, the class and aggregate number of shares set
   forth in paragraph 4 hereof that are subject to Options which previously have
   been or subsequently may be granted under the Plan shall also be
   appropriately adjusted to reflect the events described in such subparagraphs.
   The Committee or the Successor Board shall determine the specific adjustments
   to be made under this paragraph 13 and, subject to paragraph 2, its
   determination shall be conclusive.


   14. MEANS OF EXERCISING OPTIONS.  An Option (or any part or installment
       ---------------------------                                        
thereof) shall be exercised by giving written notice to the Company at its
principal office address, or to such transfer agent as the Company shall
designate.  Such notice shall identify the Option being exercised and specify
the number of shares as to which such Option is being exercised, accompanied by
full payment of the purchase price therefor either (a) in United States dollars
in cash or by check, (b) at the discretion of the Committee, through delivery of
shares of Common Stock having a fair market value equal as of the date of the
exercise to the cash exercise price of the Option, (c) at the discretion of the
Committee and consistent with applicable law, through the delivery of an
assignment to the Company of a sufficient amount of the proceeds from the sale
of the Common Stock acquired upon exercise of the Option and an authorization to
the broker or selling agent to pay that amount to the Company, which sale shall
be at the participant's direction at the time of exercise, or (d) at the
discretion of the Committee, by any combination of (a), (b) and (c) above.  The
holder of an Option shall not have the rights of a shareholder with respect to
the shares covered by his Option until the date of issuance of a stock
certificate to such holder for such shares.  Except as expressly provided above
in paragraph 13 with respect to changes in capitalization and stock dividends,
no adjustment shall be made for dividends or similar rights for which the record
date is before the date such stock certificate is issued.

   15. TERM AND AMENDMENT OF PLAN.  This Plan was adopted by the Board as of
       --------------------------                                           
November 15, 1996.  The Plan shall expire at the end of the day on November 15,
2006 (except as to Options outstanding on that date).  Subject to the provisions
of paragraph 5 above, Options may be granted under the Plan prior to the date of
stockholder approval of the Plan.  The Board may terminate or amend the Plan in
any respect at any time.  Except 
<PAGE>
 
                                      -8-

as otherwise provided in this paragraph 15, in no event may action of the Board
alter or impair the rights of an optionee, without such optionee's consent,
under any Option previously granted to such optionee.

   16.   RESERVED.
         -------- 

   17.   APPLICATION OF FUNDS. The proceeds received by the Company from the
         --------------------

     Code Section 125) plus amounts deferred hereunder pursuant to a salary
     reduction agreement.

          (k)  "Highly Compensated Employee" shall include highly compensated
     active and former employees.  A highly compensated active employee is any
     Employee who performs service for the Employer during the determination
     year and who, during the determination year:  (i) received Compensation
     from the Employer in excess of $75,000 (as adjusted pursuant to Section
     415(d) of the Code); (ii) received Compensation from the Employer in excess
     of $50,000 (as adjusted pursuant to Section 415(d) of the Code) and was a
     member of the top-paid group for such year; (iii) was an officer of the
     Employer and received Compensation during such year that is greater than 50
     percent of the dollar limitation in effect under Section 415(b)(1)(A) of
     the Code; or (iv) was a 5 percent owner at any time during the
     determination year.

          If no officer has satisfied the Compensation requirement of (iii)
     above, during a determination year, the highest paid officer for such year
     shall be treated as a Highly Compensated Employee.

          For this purpose, the determination year shall be the Plan Year, and
     the Employer elects the calendar year calculation election as provided in
     Treasury Regulation (S) 1.414(q)-IT, A-14(b).

          A highly compensated former employee is any Employee who separated
     from service (or was deemed to have separated) prior to the determination
     year, performs no service for the Employer during the determination year,
     and was a highly compensated active employee for either the separation year
     or any determination year ending on or after the Employee's 55th birthday.

          If an Employee is, during a determination year, a Family member of
     either a 5 percent owner who is an active or former employee or a Highly
     Compensated Employee who is one of the 10 most highly compensated employees
     ranked on the basis of compensation paid by the Employer during such year,
     then the Family member and the 5 percent owner or top-ten Highly
     Compensated Employee shall be aggregated.  In such case, the Family member
     and 5 percent owner or top-ten Highly Compensated Employee shall be treated
     as a single employee receiving compensation and plan contributions or
     benefits equal to the sum of such compensation and contributions or
     benefits of the Family member and 5 percent owner or top-ten Highly
     Compensated Employee.

                                      -3-

          The determination of who is a Highly Compensated Employee, including
     the determinations of the number and identity of Employees in the top-paid
     group, the number of Employees treated as officers and the Compensation
     that is considered, will be made in accordance with Section 414(q) of the
     Code and the regulations thereunder.

          (l)  "Hour of Service" shall mean each hour for which an Employee is
     directly or indirectly paid, or entitled to payment, by the Company for the
     performance of duties (such hours to be credited for the computation period
     in which the duties were performed), each hour for which back pay,
     irrespective of mitigation of damages, has been either awarded or agreed to
     by the Company (such hours to be credited for the computation period to
     which the award or agreement pertains), and each hour for which an Employee
     is directly or indirectly paid, or entitled to payment, by the Company for
     reasons (such as vacation, sickness, disability, holidays, paid layoff and
     similar paid periods of nonworking time) other than the performance of
     duties (such hours to be credited for the computation period in which such
     period of nonworking time first occurs).

          With respect to an Employee who is absent from work for any period (i)
     by reason of the pregnancy of the Employee; (ii) by reason of the birth of
     a child of the Employee; (iii) by reason of the placement of a child with
     the Employee in connection with the adoption of such child by such
     Employee, or (iv) for purposes of caring for such child for a period
     beginning immediately following such birth or placement, then solely for
     purposes of determining whether a One-Year Break in Service has occurred,
     such Employee shall be credited with the Hours of Service which otherwise
     would have been credited to such Employee but for such absence.  In the
     event that the Plan Administrator is unable to determine the Hours of
     Service with respect to such absence, the Employee shall be credited with
     eight Hours of Service for each normal workday of such absence.  No credit
     for Hours of Service shall be granted with respect to an absence described
     in this paragraph if the Employee fails to timely provide information
     required by the Plan Administrator which is reasonably required to
     establish that the Employee was absent from work for a reason described in
     this paragraph and to establish the number of days for which there was such
     an absence.  Hours of Service which are credited pursuant to this paragraph
     shall be credited only in the Plan Year in which the absence from work
     begins (if the Employee would be prevented from incurring a One-Year Break
     in Service in such year solely because the Employee is credited with Hours
     of Service pursuant to this paragraph), or in any other case, in the
     immediately following Plan Year.

          No more than 501 Hours of Service shall be credited to an Employee on
     account of any single continuous period during which the Employee performs
     no duties.  In addition to the foregoing, the rules set forth at Sections
     2530.200b-2(b) and 2(c) of the Department of Labor Regulations shall apply
     in determining Hours of Service.

          An Hour of Service respecting any member of a controlled group of
     corporations or any member of an affiliated service group (as defined in
     Section 414(b), 414(m) or 414(o) of the Code) of which the Company is a
     member, or respecting an unincorporated trade or business which is under
     common control with the Company (as defined in Section 414(c) of the Code)
     or any other entity required to be aggregated with the Company under

     contributions" or "excess aggregate contributions" within the meaning of
     subparagraphs 7. C. or 7. D., below for the Plan Year in which such excess
                   -- --    -- --
     contribution was made. The amount of income attributable to such excess
     contributions shall be determined by the Administrator in a reasonable and
     consistent manner. Income shall not include income allocable to excess
     contributions for the Plan Year in which the excess contribution is
     returned to the Participant.

          (n)  "Non-Highly Compensated Employee" shall mean an Employee who is
     neither a Highly Compensated Employee nor a member of his Family.

          (o)  "Normal Retirement Age" shall mean age sixty-five (65).

          (p)  "One-Year Break in Service" shall mean a Plan Year during which
     an Employee does not complete more than one Hour of Service with the
     Company. For purposes of determining eligibility to participate in the
     Plan, such 12-month period shall be calculated with reference to the
     Employee's "Employment Commencement Date" (as defined in subparagraph 2.(w)
                                                                           -
     below), and annual anniversaries thereof. For purposes of determining the
     nonforfeitable percentage of a Participating Employee's share in the Trust,
     such 12-month period shall be deemed to be the Plan Year.

          (q)  "Participating Employee" and "Participant" shall mean any
     Employee of the Company who is eligible to participate in Company
     contributions to the Plan and Trust. "Beneficiary" shall mean a person who

     Participating Employee or as beneficiary of a deceased Beneficiary.

          (w)  "Vesting Year of Service" shall mean a period of twelve (12)
     consecutive months during which a Participating Employee completes at least
     one (1) Hour of Service.  Such 12-month period shall be calculated with
     reference to the Employee's "Employment Commencement Date" (the first date
     of employment on which the Employee is credited with an Hour of Service
     with the Company), and subsequent such 12-month periods shall be calculated
     with reference to subsequent anniversaries of said Employment Commencement
     Date.  In determining Vesting Years of Service, service with Harcourt Brace
     Jovanovich, Inc. shall be considered as service with the Company.

     employment of the Company, shall continue to be credited with Vesting Years
     of Service under this Plan so long as he remains in the employment of the
     Company.  An Employee who was in the employment of the Company before he
     became an Employee for purposes of this Plan shall receive credit for
     Vesting Years of Service as though he had been an Employee during such
     prior period of employment with the Company.

     employment on which the Employee is credited with an Hour of Service with
     the Company), and subsequent such 12-month periods shall be calculated with
     reference to subsequent anniversaries of said Employment Commencement Date.

deemed to include the plural, the plural to include the singular, the masculine
to include the feminine and neuter, the feminine to include the masculine and
neuter, and the neuter to include the masculine and feminine.

     3.   Purpose.
     --   ------- 

                                      -6-
<PAGE>
 
     This Trust was created and continues in existence for the purpose of
enabling eligible Employees of the Company to defer a portion of their
compensation until retirement and to share in the profits of the Company's
business.  Except as provided in Paragraph 32. below, in no event shall any part
                                           ---                                  
of the principal or income of this Trust be paid to or revested in the Company,
or be used for any purpose whatsoever other than the exclusive benefit of such
Employees and their Beneficiaries.

     All discretionary acts taken by the Trustee hereunder shall be uniform in
their nature and application to all persons similarly situated, and no
discretionary acts shall be taken which shall be discriminatory under the
provisions of the Code or the Employee Retirement Income Security Act of 1974,
as they relate to employees' profit-sharing trusts, as such provisions now exist
or may from time to time be amended.

     4.   Plan Entry Requirements.
     --   ----------------------- 

     Each Employee of the Company shall enter the Plan on the first day of the
calendar month next following the later to occur of the end of the 12-month
period of service which constitutes a Year of Service with respect to such
Employee and his attainment of age twenty-one (21).  Prior to January 1,  1991,
each Employee of the Company shall enter the Plan on the January 1 or July 1
next following the later to occur of the end of the 12-month period of service
which constitutes a Year of Service with respect to such Employee and his
attainment of age twenty-one (21).  An Employee who has met the Plan entry
requirements may elect not to participate in the Plan by providing the Company
with written notice of his or her election not to be included as a Participant.
Said election shall remain in effect until the Employee provides the Company
with written notice of his or her election to become a Participant.

     With respect to an Employee who has met the eligibility requirements of the
Plan but who has incurred a One-Year Break in Service, such Employee shall be
eligible to re-enter the Plan commencing immediately upon his return.  In the
event an Employee who is not a member of an eligible class of employees becomes
a member of an eligible class, such employee will participate immediately if
such Employee has satisfied the minimum age and service requirements and would
have otherwise previously become a Participant.  In the event that the
eligibility of any person to participate in the Plan shall be disputed, the
decision of the Trustee upon such eligibility shall be controlling.  For the
purposes of enabling the Trustee to make such determination, all information
available to the Company which shall be required by the Trustee shall be made
available to the Trustee.

     5.   Contributions.
     --   ------------- 

     Subject to the provisions of subparagraphs 8. H. and 8. I. below,

Plan shall be made as follows:

          A.   Salary Reduction Contributions.  Each Participant may elect to
          --   ------------------------------                                
     enter into a salary reduction agreement with the Company under which the
     Participant agrees to accept a reduction in salary from the Company (such
     reduction not to exceed fifteen percent (15%) of such Participant's Gross
     Compensation with respect to any Plan Year).  Said salary reduction
     agreement shall be filed by the Participant with the Company within 30 days
     prior to the payment of Compensation to which such salary reduction
     agreement applies.  In consideration of such agreement, the Company will
     make a salary reduction contribution to the Participant's Salary Reduction
     Contribution Account on behalf of the Participant for such Plan Year in an
     amount equal to the total amount by which the Participant's Compensation
     from the Company was reduced during the Plan Year pursuant to the salary
     reduction agreement.  Contributions made by the Company for a given Plan
     Year pursuant to salary reduction agreements shall be deposited with the
     Trustee within a reasonable amount of time, but in no event will such
     deposit be made more than 90 days following the date such funds are
     withheld from the Participant's salary.

          Salary reduction contributions made pursuant to this subparagraph A.
                                                                            --
     shall be governed by the following additional provisions:

               (1)  Amounts credited to a Participant's Salary Reduction Account
          shall be 100 percent vested and nonforfeitable at all times.

               (2)  Amounts credited to a Participant's Salary Reduction Account
          shall be considered as a contribution made by the Company for purposes
          of subparagraphs 8. H., 8. I. and 26. B.
                           -- --  -- --     --- --

               (3)  A salary reduction agreement may provide for a reduction in
          salary by means of reducing the Participant's payroll on a periodic
          basis, or the agreement may provide for lump sum reductions with
          respect to any compensation payments in such amounts that will not
          cause the limitations of Paragraphs 7., 8. H., or 8. I. to be
                                              --  -- --     -- --      
          exceeded.

               (4)  A salary reduction agreement providing for reductions to a
          Participant's periodic payroll may be cancelled at any time by a
          Participant by giving at least 30 days advance written notice to the
          Company, specifying the effective date of the cancellation.  A
          Participant may change the rate of his salary reduction four (4) times
          per Plan Year, to be effective as of any January 1, April 1, July 1,
          or October 1 following such election, by filing an amended salary
          reduction agreement with the Company within thirty (30) days prior to
          said date.

                                      -8-
<PAGE>
 
               (5)  The Company may refrain from making contributions to this
          Plan, in respect of the salary reduction agreement entered into by the
          Participant, if the Company determines that such action is necessary
          to insure that the Participant's annual additions for any Plan Year
          will not exceed the limitations of subparagraphs 8. H. or 8. I.
                                                           -- --    -- --
          hereinbelow, or to insure that the Actual Deferral Percentage Test
          described in Paragraph 7. hereinbelow is met for such Plan Year.  In
                                 --                                           
          any such event, the Company may pay to the Participant the amount
          which otherwise would have been paid prior to the Participant's
          election to reduce his salary, rather than as a contribution made
          pursuant to a salary reduction agreement.

               (6)  A salary reduction agreement shall not provide for a
          reduction in excess of $7,000 (or such higher amount as determined by
          the Secretary pursuant to Section 415(d) of the Code) under all plans
          maintained by the Company with respect to any Employee's taxable year.

          B.   Matching Company Contributions.  Not later than the time
          --   ------------------------------                          
     prescribed by law for filing its federal income tax return (including any
     extensions thereof) for its current taxable year, the Company shall
     contribute to the Trustee, on behalf of each Participant, as its Matching
     Company Contribution to the Trust for the Plan Year which ends within or
     which is co-terminous with such taxable year of the Company, to be held in
     trust, administered and distributed under the terms of this Agreement, an
     amount to be determined as follows:

               (1)  With respect to Salary Reduction Contributions up to the
          first two percent (2%) of the Participant's Gross Compensation, the
          Matching Company Contribution shall be equal to 100% of the Salary
          Reduction Contribution;

               (2)  With respect to Salary Reduction Contributions in excess of
          two percent (2%) of the Participant's Gross Compensation and not in
          excess of six percent (6%) of the Participant's Gross Compensation,
          the Matching Company Contribution shall be equal to 25% of such Salary
          Reduction Contribution; and

               (3)  With respect to Salary Reduction Contributions in excess of
          six percent (6%) of the Participant's Gross Compensation, there shall
          be no Matching Company Contribution.  In no event shall the Matching
          Company Contribution made on behalf of a Participant in a Plan Year
          exceed three percent (3%) of the Participant's Gross Compensation.

          In determining the Matching Company Contribution, the computation of
     the Salary Reduction Contribution as a percentage of Gross Compensation
     shall be made on a per payroll basis.

                                      -9-
<PAGE>
 
          Notwithstanding the foregoing, the Company shall not contribute to the
     Plan as a Matching Company Contribution any amount that would cause the
     limitation set forth in Paragraph 7. to be exceeded, considering only
                                       --                                 
     Matching Company Contributions, rather than Salary Reduction Contributions.

          C.   Discretionary Company Contributions.  Not later than the time
          --   -----------------------------------                          
     prescribed by law for filing its federal income tax return (including
     extensions thereof) for its current taxable year and for each succeeding
     taxable year, the Company may contribute to the Trust fund, as its
     contribution to this Trust for the Plan Year which ends within or which is
     co-terminous with such taxable year of the Company, to be held in trust,
     administered and distributed under the terms of this Agreement, an amount
     or amounts which the Company, in its sole discretion may determine.  The
     Company may contribute such amount or amounts at any time; and it may make
     such contribution in two or more installments.

          The Company shall determine by resolution of its Board of Directors
     and communicate to the Trustee before the close of each Plan Year either
     (i) the amount in dollars to be contributed for such year, or (ii) a
     formula by which such amount may be determined.  These contributions shall
     be totally in the discretion of the Company with respect to amount, timing
     and form, and they need not be limited to the profits of the Company.  The
     Company may make such contributions in cash or in kind.  Nothing in this
     Agreement shall entitle any Trustee, Participating Employee or Beneficiary
     to inquire into or demand the right to inspect the books or records of the
     Company.

          D.   Rollover Contributions.  An Employee, whether or not he would
          --   ----------------------                                       
     otherwise be a Participant in the Plan, may contribute a "Rollover
     Contribution" to the Trust by delivery of such contribution to the Trustee;
     provided that such Employee submits a written certification that such
     contribution qualified as a Rollover Contribution as defined hereinbelow.

          For purposes of this subparagraph D., for an amount to qualify for
                                            --                              
     contribution by an Employee as a Rollover Contribution, it must:

               (1)  represent the balance to the credit of such Employee under a
          plan qualified under Section 401 of the Code, and have been paid to
          him:

                    (a)  within one taxable year of the Employee on account of
               the termination of such plan, or if such plan was a profit-
               sharing or stock bonus plan, upon complete discontinuance of
               Employer contributions thereto, or

                    (b)  in one or more distributions which constitute a lump 
               sum

                                     -10-
<PAGE>
 
               distribution; or

               (2)  represent the balance to his credit of a conduit Individual
          Retirement Account or similar account or annuity, unless such balance
          is derived in any part from a previous rollover of a partial qualified
          plan contribution; and (in either the case of compliance with
          subdivision (1) above or this subdivision (2)); and

               (3)  be contributed to the Plan within 60 days following
          distribution of such amount to the Employee.

          In addition to the foregoing, the provisions of Code Sections
     402(a)(6)(C), (D) and 402(a)(7) shall apply in determining the
     permissibility of a desired Rollover Contribution by an Employee.

          An amount will not qualify as a Rollover Contribution if it includes
     any amount which constituted a contribution made by the Employee to a plan
     qualified under Section 401 of the Code.

          A Rollover Contribution shall be considered as a part of the account
     of the contributing Employee in this Plan, shall be fully vested and
     nonforfeitable, and shall be accounted for separately from Company
     contributions.

          A Participant may also arrange for the direct transfer of his benefit
     from a plan qualified under Section 401 of the Code to this Plan.  For
     accounting and record keeping purposes, transfer contributions shall be
     identical to Rollover Contributions.

          If a Rollover Contribution is from a plan that is subject to the
     provisions of Code Section 417, with respect to qualified joint and
     survivor annuities and qualified preretirement survivor annuities, the
     rules of said Section 417 shall continue to apply to the Participant's
     Rollover Contribution Account.

     6.   Withdrawals.
     --   ----------- 

          A.   Age 59-1/2.  A Participant who has attained age 59-1/2 may
          --   ----------                                                
     withdraw all or any portion of his Salary Reduction Account by notifying
     the Trustee of his election to make such a withdrawal.

          B.   Hardship.  In the event a Participant who has not attained age 59
          --   --------                                                         
     1/2 suffers a serious financial hardship, such Participant may withdraw a
     portion of his account attributable to his Salary Reduction Contributions
     (but not the earnings on such 

                                     -11-
<PAGE>
 
     contributions) as provided hereinbelow. The determination of whether a
     serious financial hardship exists shall be based on all relevant facts and
     circumstances. A need shall not be disqualified because it was reasonably
     foreseeable or voluntarily incurred. Withdrawal under this subparagraph 6.
                                                                             --
     B. shall be authorized only if the distribution is on account of:
     --

               (1)  Medical expenses described in Code Section 213(d) incurred
          by the Participant, his spouse, or any of his dependents (as defined
          in Code Section 152);

               (2)  The purchase (excluding mortgage payments) of a principal
          residence for the Participant;

               (3)  Payment of tuition for the next semester or quarter of post-
          secondary education for the Participant, his spouse, children, or
          dependents; or

               (4)  The need to prevent the eviction of the Participant from his
          principal residence or foreclosure on the mortgage of the
          Participant's principal residence.

          C.   Conditions for Hardship Distribution.  No distribution shall be
          --   ------------------------------------                           
     made pursuant to Paragraph 6. B. above unless the Administrator, based upon
                                -- --                                           
     the Participant's representation and such other facts as are known to the
     Administrator, determines that the following conditions are satisfied:

               (1)  The distribution is not in excess of the amount of the
          immediate and heavy financial need of the Participant; and

               (2)  The Participant has obtained all distributions, other than
          hardship distributions, and all nontaxable loans currently available
          under all plans maintained by the Employer.

          D.   Available Other Resources.  No distribution shall be made
          --   -------------------------
     pursuant to subparagraph 6. B. unless the Administrator determines, based
                              -- -
     upon all relevant facts and circumstances, that the amount to be
     distributed is not in excess of the amount required to relieve the
     financial need and that such need cannot be satisfied from other resources
     reasonably available to the Participant. For this purpose, the
     Participant's resources shall be deemed to include those assets of his
     spouse and minor children that are reasonably available to the Participant.
     A distribution may be treated as necessary to satisfy a financial need if
     the Administrator relies upon the Participant's representation that the
     need cannot be relieved:

                                     -12-
<PAGE>
 
               (1)  Through reimbursement or compensation by insurance or
          otherwise;

               (2)  By reasonable liquidation of the Participant's assets, to
          the extent such liquidation would not itself cause an immediate and
          heavy financial need;

               (3)  By cessation of Salary Reduction Contributions and voluntary
          Employee contributions, if available, under the Plan; or

               (4)  By other distributions or loans from the Plan, if available,
          or any other qualified retirement plan, or by borrowing from
          commercial sources on reasonable commercial terms.

     7.   Special Nondiscrimination Testing.
     --   --------------------------------- 

          A.   Actual Deferral Percentage Tests.  For each Plan Year the Plan
          --   --------------------------------                              
     shall satisfy one of the following tests:

               (1)  The "Actual Deferral Percentage" for the Highly Compensated
          Employee group shall not be more than the "Actual Deferral Percentage"
          of the Non-Highly Compensated Employee group multiplied by 1.25, or

               (2)  The excess of the "Actual Deferral Percentage" for the
          Highly Compensated Employee group over the "Actual Deferral
          Percentage" for the Non-Highly Compensated Employee group shall not be
          more than two percentage points. Additionally, the "Actual Deferral
          Percentage" for the Highly Compensated Employee group shall not exceed
          the "Actual Deferral Percentage" for the Non-Highly Compensated
          Employee group multiplied by 2. The provisions of Code Section
          401(k)(3) and Regulation 1.401(k)-1(b) are incorporated herein by
          reference.

          For the purposes of this Paragraph 7. "Actual Deferral Percentage"
                                             --                             
     means, with respect to the Highly Compensated Employee group and Non-Highly
     Compensated Employee group for a Plan Year, the average of the ratios,
     calculated separately for each Participant in such group, of the amount of
     Salary Reduction Contributions allocated to each Participant's Salary
     Reduction Contribution Account for such Plan Year to such Participant's
     Compensation for such Plan Year. The actual deferral ratio for each
     Participant and the "Actual Deferral Percentage" for each group shall be
     calculated to the nearest one-hundredth of one percent.

          For the purpose of determining the actual deferral ratio of a Highly
     Compensated 

                                     -13-
<PAGE>
 
     Employee who is subject to the Family Member aggregation rules of Code
     Section 414(q)(6) because such Participant is either a "five percent owner"
     of the Employer or one of the ten (10) Highly Compensated Employees paid
     the greatest "415 Compensation" during this year, the following shall
     apply:

               (1)  The combined actual deferral ratio for the family group
          (which shall be treated as one Highly Compensated Employee) shall be
          the greater of (i) the ratio determined by aggregating Salary
          Reduction Contributions and Gross Compensation of all eligible Family
          Members who are Highly Compensated Employees without regard to family
          aggregation; and (ii) the ratio determined by aggregating Employees
          Contributions and Gross Compensation of all eligible Family Members
          (including Highly Compensated Employees).

               (2)  The Salary Reduction Contributions and Gross Compensation of
          all Family Members shall be disregarded for purposes of determining
          the "Actual Deferral Percentage" of the Non-Highly Compensated
          Employee group except to the extent taken into account in paragraph
          (1) above.

               (3)  If a Participant is required to be aggregated as a member of
          more than one family group in a plan, all Participants who are members
          of those family groups that include the Participant are aggregated as
          one family group in accordance with paragraphs (1) and (2) above.

          For the purposes of this subparagraph 7. A., a Highly Compensated
                                                -- --                      
     Employee and a Non-Highly Compensated Employee shall include any Employee
     eligible to make a Salary Reduction Contribution pursuant to subparagraph
     5. A., whether or not such deferral election was made or suspended pursuant
     -- --                                                                      
     to subparagraph 5. A.
                     -- --

          For the purposes of this subparagraph 7. A. and Code Sections
                                                -- --                  
     401(a)(4), 410(b) and 401(k), if two or more plans which include cash or
     deferred arrangements are considered one plan for the purposes of Code
     Section 410(a)(4) or 410(b) (other than Code Section 410(b)(2)(A)(ii)), the
     cash or deferred arrangements included in such plans shall be treated as
     one arrangement.  In addition, two or more cash or deferred arrangements
     may be considered as a single arrangement for purposes of determining
     whether or not such arrangements shall be treated as one arrangement and as
     one plan for purposes of this subparagraph 7. A. and Code Sections
                                                -- --                  
     401(a)(4), 410(b) and 401(k).  For Plan Years beginning after December 31,
     1989, plans may be aggregated under this subparagraph 7. A. only if they
                                                           -- --             
     have the same plan year.

          Notwithstanding the above, an employee stock ownership plan described
     in Code Section 4975(e)(7) may not be combined with this Plan for purposes
     of determining whether the employee stock ownership plan or this Plan
     satisfies this subparagraph 7. A. 
                                 -- --                                        

                                     -14-
<PAGE>
 
     and Code Sections 401(a)(4), 410(b) and 401(k).

          For the purpose of this subparagraph 7. A., if a Highly Compensated
                                               -- --                         
     Employee is a Participant under two or more cash or deferred arrangements
     of the Employer, all such cash or deferred arrangements shall be treated as
     one cash or deferred arrangement for the purpose of determining the actual
     deferral ratio with respect to such Highly Compensated Employee.  However,
     if the cash or deferred arrangements have different Plan Years, this
     paragraph shall be applied by treating all cash or deferred arrangements
     ending with or within the same calendar year as a single arrangement.

          B.   Actual Contribution Percentage Tests.  For each Plan Year, the
          --   ------------------------------------                          
     Plan shall satisfy one of the following tests:

               (1)  The "Actual Contribution Percentage" for the Highly
          Compensated Employee group shall not be more than the "Actual
          Contribution Percentage" of the Non-Highly Compensated Employee group
          multiplied by 1.25, or

               (2)  The excess of the "Actual Contribution Percentage" for the
          Highly Compensated Employee group over the "Actual Contribution
          Percentage" for the Non-Highly Compensated Employee group shall not be
          more than two percentage points.  Additionally, the "Actual
          Contribution Percentage" for the Highly Compensated Employee group
          shall not exceed the "Actual Contribution Percentage" for the Non-
          Highly Compensated Employee group multiplied by 2.

          However, to prevent the multiple use of the alternative method (2)
     described in this paragraph and Code Section 401(m)(9)(A), any Highly
     Compensated Employee eligible to make Salary Reduction Contributions or to
     receive Matching Company Contributions under this Plan shall have his
     actual contribution ratio reduced pursuant to Regulation 1.401(m)-2.  The
     provisions of Code Section 401(m) and Regulations 1.401(m)-1(b) and
     1.401(m)-2 are incorporated herein by reference.

          For the purposes of this Plan, "Actual Contribution Percentage" for a
     Plan Year means, with respect to the Highly Compensated Employee group and
     Non-Highly Compensated Employee group, the same as Actual Deferral
     Percentage as computed in subparagraph 7. A., but substituting "Matching
                                            -- --                            
     Company Contributions" for "Salary Reduction Contributions."

          For purposes of determining the "Actual Contribution Percentage" and
     the amount of Excess Aggregate Contributions pursuant to subparagraph 7.
                                                                           --
     D., only Company Matching Contributions contributed to the Plan prior to
     --                                                                      
     the end of the succeeding Plan Year shall be considered.

          C.   Adjustment to Actual Deferral Percentage Tests. In the event that
          --   ----------------------------------------------
     the initial allocations of the Salary Reduction Contributions do not
     satisfy one of the tests set forth in subparagraph 7. A., the Administrator
                                                        -- -
     shall adjust Excess Contributions (i.e., Salary Reduction Contributions in
     excess of the limits established by the tests set forth in subparagraph 7.
                                                                             --
     A.) as set forth below:
     --                     

               (1)  On or before the fifteenth day of the third month following
          the end of each Plan Year, the Highly Compensated Employee having the
          highest actual deferral ratio shall have his portion of Excess
          Contributions distributed to him until one of the tests set forth in
          subparagraph 7. A. is satisfied, or until his actual deferral ratio
                       -- --                                                 
          equals the actual deferral ratio of the Highly Compensated Employee
          having the second highest actual deferral ratio.  This process shall
          continue until one of the tests set forth in subparagraph 7. A. is
                                                                    -- --   
          satisfied.  For each Highly Compensated Employee, the amount of Excess
          Contributions is equal to the Salary Reduction Contributions on behalf
          of such Highly Compensated Employee (determined prior to the
          application of this paragraph) minus the amount determined by
          multiplying the Highly Compensated Employee's actual deferral ratio
          (determined after application of this paragraph) by his Gross
          Compensation.  However, in determining the amount of Excess
          Contributions to be distributed with respect to an affected Highly
          Compensated Employee as determined herein, such amount shall be
          reduced by any Salary Reduction Contributions previously distributed
          to such affected Highly Compensated Employee for his taxable year
          ending with or within such Plan Year.

               With respect to the distribution of Excess Contributions as
          described above, such distribution:

                    (a)  may be postponed but not later than the close of the
               succeeding Plan Year;

                    (b)  shall be adjusted for Income; and

                    (c)  shall be designated by the Employer as a distribution
               of Excess Contributions (and Income).

               The determination and correction of Excess Contributions of a
          Highly Compensated Employee whose actual deferral ratio is determined
          under the family aggregation rules shall be accomplished by allocating
          the Excess Contributions for the family unit among the Family Members
          in proportion to the Elective Contributions of each Family Member that
          were combined to determine the group actual deferral ratio.

          D.   Adjustment to Actual Contribution Percentage Tests.  In the event
          --   --------------------------------------------------               
     that the "Actual Contribution Percentage" for the Highly Compensated
     Employee group exceeds the "Actual Contribution Percentage" for the Non-
     Highly Compensated Employee group pursuant to subparagraph 7. B., the
                                                                -----     
     Administrator (on or before the fifteenth day of the third month following
     the end of the Plan Year, but in no event later than the close of the
     following Plan Year) shall direct the Trustee to distribute to the Highly
     Compensated Employee having the highest actual contribution ratio, his
     portion of Excess Aggregate Contributions (i.e., Matching Company
     Contributions in excess of the limits established by the tests set forth in
     subparagraph 7. B.) and Income allocable to such contributions or, if
                  -- --                                                   
     forfeitable, forfeit such non-Vested Excess Aggregate Contributions
     attributable to Matching Company Contributions (and Income allocable to
     such Forfeitures) until either one of the tests set forth in subparagraph
     7. B. is satisfied, or until his actual contribution ratio equals the
     -- --                                                                
     actual contribution ratio of the Highly Compensated Employee having the
     second highest actual contribution ratio.  This process shall continue
     until one of the tests set forth in subparagraph B. is satisfied.
                                                      --              
          Any distribution and/or Forfeiture of less than the entire amount of
     Excess Aggregate Contributions (and Income) shall be treated as a pro rata
     distribution and/or Forfeiture of Excess Aggregate Contributions and
     Income.  Distribution of Excess Aggregate Contributions shall be designated
     by the Employer as a distribution of Excess Aggregate Contributions (and
     Income).  Forfeitures of Excess Aggregate Contributions shall be treated in
     accordance with subparagraph 9. D.  However, no such Forfeiture may be
                                  -- --                                    
     allocated to a Highly Compensated Employee whose contributions are reduced
     pursuant to this subparagraph.

          Excess Aggregate Contributions shall be treated as Employer
     contributions for purposes of Code Sections 404 and 415 even if distributed
     from the Plan.

          For each Highly Compensated Employee, the amount of Excess Aggregate
     Contributions is equal to the Matching Company Contributions made pursuant
     to subparagraph 5. B. (determined prior to the application of this
                     -- --                                             
     paragraph) minus the amount determined by multiplying the Highly
     Compensated Employee's actual contribution ratio (determined after
     application of this paragraph) by his Gross Compensation.  The actual
     contribution ratio must be rounded to the nearest one-hundredth of one
     percent.  In no case shall the amount of Excess Contribution with respect
     to any Highly Compensated Employee exceed the amount of Matching Company
     Contributions made pursuant to subparagraph 5. B. on behalf of such Highly
                                                 -- --                         
     Compensated Employee for such Plan Year.

     --   -------------------------------------------------------------
          Benefits.

          A.   Establishment of Investment Funds.  With respect to each Plan

     Year, the 

                                     -17-
<PAGE>
 
     Company and Trustee may designate and describe one or more investment funds
     available for the allocation of Participants' accounts. Subject to
     Paragraph 13., the Trustee shall have the responsibility to decide the
               ---
     allocation of contributions which shall be made to the available Funds. The
     Company may delegate this responsibility to each Participant in a
     consistent and nondiscriminatory manner. In the event the Company so
     delegates the investment responsibility to Participants, each Participating
     Employee shall have the opportunity to designate the manner in which his
     account will be allocated among the available Funds, in accordance with the
     provisions of subparagraph 8. B.
                                -- --

          B.   Selections.  The designation by a Participant of the allocation
          --   ----------
     of his account among the available investment funds may be made from time
     to time, with such frequency and in accordance with such procedures as
     established by the Trustee and applied in a uniform nondiscriminatory
     manner. Any such procedure shall be communicated to the Participants and
     designed with the intention of permitting the Participants to exercise
     control over the assets in their respective accounts within the meaning of
     Section 404(c) of the Employee Retirement Income Security Act and the
     regulations promulgated thereunder. If and to the extent that a Participant
     shall fail to designate an allocation of his account under this
     subparagraph 8.B., the Trustee shall select a Fund or Funds to which such
                  ----
     amount shall be allocated. Otherwise, the Company shall instruct the
     Trustee to allocate and invest the assets of the Trust in accordance with
     the Participant's selections.

          If and to the extent that the account of a Participant or Beneficiary
     herein is directed to be invested pursuant to this paragraph, no person who
     is otherwise a fiduciary hereunder shall be liable to the directing
     Participant or Beneficiary for any particular loss, for failure to
     diversify assets, or in any other respect regarding such directed
     investment.  No investment shall be directed by a Participant or
     Beneficiary, nor made by the Trustee even if so directed, which would
     directly or indirectly inure to the benefit of the Company or which would
     constitute a prohibited transaction under applicable law and regulations.

          C.   Separate Records.  The Trustee shall maintain a separate account
          --   ----------------                                                
     in the name of each Participating Employee and each Beneficiary having a
     share in the Trust.  Separate records shall be kept of:

               (1)  the portion of each Participating Employee's share or
          account resulting from Company contributions made pursuant to a salary
          reduction agreement (such amounts to be recorded in a "Salary
          Reduction Contribution Account");

               (2)  the portion of each Participating Employee's share or
          account resulting from Matching Company Contributions intended to
          supplement amounts contributed pursuant to a salary reduction
          agreement (such amount to be recorded 

                                     -18-
<PAGE>
 
          in a "Matching Company Contribution Account");

               (3)  the portion of each Participating Employee's share or
          account resulting from the Company's Discretionary Contributions (such
          amounts to be recorded in a "Company Discretionary Contribution
          Account").

               (4)  the portion of each Participating Employee's share or
          account resulting from the Participating Employee's Rollover
          Contribution (such amount to be recorded in a "Rollover Contribution
          Account").

     To that end, wherever in this Agreement reference is made to the "share" or
     "account" of a Participating Employee, the word "share" or "account" where
     the context so permits, shall be deemed to refer severally to the Salary
     Reduction Contribution Account, the Company Matching Contribution Account,
     the Company Discretionary Contribution Account, and the Rollover
     Contribution Account, each such account being adjusted for income and
     expense credited or charged as hereinafter described.

          D.   Allocation of Income and Expenses.  As of each Revaluation Date,
          --   ---------------------------------                               
     all income of the Trust for the period since the preceding Revaluation Date
     shall be credited to, and all losses and expenses of the Trust for such
     period shall be charged to, the various Accounts maintained by the Trustee
     for the Participating Employees and Beneficiaries.  Such credits and
     charges shall be made in proportion to the value of the respective
     Participating Employee and Beneficiary Accounts as of the preceding
     Revaluation Date (after recording all credits and charges which would
     otherwise be made based on Account balances as of the preceding Revaluation
     Date).  Further, the Trustee may adjust in a nondiscriminatory and
     consistent manner the credits and charges which would otherwise be made
     based on Account balances as of the preceding Revaluation Date to take into
     account inter-Fund transfers, periodic contributions made on behalf of
     Participants, repayments of Participant loans or borrowing by Participants,
     Rollover contributions, or any other transactions occurring since the
     preceding Revaluation Date.

          Any loan extended by the Trustee to a Participant pursuant to
     Paragraph 11. hereinbelow shall be deemed, for purposes of allocation of
               ---                                                           
     income, as an earmarked investment made for such Participant's benefit.
     Accordingly, all interest or other earnings attributable to such loan shall
     be allocated and credited exclusively to the account of the Participant to
     whom such loan was made.

          E.   Revaluation of Assets.  As of each Revaluation Date, the Trustee
          --   ---------------------                                           
     shall revalue the various Accounts maintained by the Trustee for the
     Participating Employees and Beneficiaries, to the end that such Employee
     and Beneficiary Accounts will reflect any increase or decrease in fair
     market value of the assets of the Trust as of such date.  Any such increase
     or decrease in market value shall be apportioned in the same manner 

                                      -19-
<PAGE>
 
     that income, expenses, and losses are to be apportioned in accordance with
     the provisions of this Paragraph 8.

          F.   List of Participants.  On or about the Anniversary Date ending
          --   --------------------                                          
     each Plan Year, the Company shall deliver to the Trustee a list of all
     Employees eligible on such date to participate herein, to whom Compensation
     was paid or payable for such year, together with a statement of the amount
     of such Compensation, and the amount by which such Compensation was reduced
     pursuant to a salary reduction agreement.

          G.   Allocation of Contributions.  The Trustee shall credit to the
          --   ---------------------------                                  
     Salary Reduction Contribution Account of each Participant, from the
     Company's current contribution, an amount equal to the amount set forth in
     the salary reduction agreement in effect with such Participant.

          The Trustee shall credit to the Matching Company Contribution Account
     of each Participant who makes Salary Reduction Contributions, an amount
     equal to the amount required to be contributed pursuant to Paragraph 5. B.
                                                                          -- --

          As of the Anniversary Date ending each Plan Year for which the Company
     shall make a Discretionary contribution hereunder, the Trustee shall credit
     to the Company Discretionary Account of each Participating Employee
     employed by the Company on such day and who has completed at least one (1)
     Hour of Service during such Plan Year (irrespective of whether such
     Participant has made a Salary Reduction Contribution), an amount which
     bears the same ratio to the total of the Company's Profit-Sharing
     Contribution as such Employee's Gross Compensation for such year shall bear
     to the aggregate of the Gross Compensation of all Participating Employees
     for such year.

          In the case of a Participating Employee who is entitled to have
     credited to his account a portion of a Company Discretionary contribution
     for such year but whose employment is terminated after the close of such
     year and before such contribution has been made to the Trust and such
     credit effected, such credit shall be effected as though such Employee's
     employment had not terminated.

          In addition, from time to time the Trustee shall credit to the other
     accounts of each Employee the amounts contributed by him to the Plan which
     constitute Rollover Contributions.

          H.   Limitation on Annual Additions.  If the Participant does not
          --   ------------------------------                              
     participate in, and has never participated in another qualified plan
     maintained by the employer or a welfare benefit fund, as defined in Section
     419(e) of the Code maintained by the employer, or an individual medical
     account, as defined in Section 415(1)(2) of the Code, maintained by the
     employer, which provides an annual addition as defined in 

                                      -20-
<PAGE>
 
     subparagraph 8. J.(6), the amount of annual additions which may be credited
                  -- - 
     to the Participant's account for any limitation year will not exceed the
     lesser of the maximum permissible amount or any other limitation contained
     in this Plan. If the employer contribution that would otherwise be
     contributed or allocated to the Participant's account would cause the
     annual additions for the limitation year to exceed the maximum permissible
     amount, the amount contributed or allocated will be reduced so that the
     annual additions for the limitation year will equal the maximum permissible
     amount.

          Prior to determining the Participant's actual compensation for the
     limitation year, the employer may determine the maximum permissible amount
     for a Participant on the basis of a reasonable estimation of the
     Participant's compensation for the limitation year, uniformly determined
     for all Participants similarly situated.  As soon as is administratively
     feasible after the end of the limitation year, the maximum permissible
     amount for the limitation year will be determined on the basis of the
     Participant's actual compensation for the limitation year.  If as a result
     of forfeitures or as a result of exceeding the maximum permissible amount,
     there is an excess amount the excess will be disposed of as follows:

               (1)  Any nondeductible voluntary employee contributions, to the
          extent they would reduce the excess amount, will be returned to the
          Participant;

               (2)  If after the application of subparagraph (1) an excess
          amount still exists, and the Participant is covered by the Plan at the
          end of the limitation year, the excess amount in the Participant's
          account will be used to reduce employer contributions (including any
          allocation of forfeitures) for such Participant in the next limitation
          year, and each succeeding limitation year if necessary;

               (3)  If after the application of subparagraph (1) an excess
          amount still exists, and the Participant is not covered by the Plan at
          the end of a limitation year, the excess amount will be held
          unallocated in a suspense account. The suspense account will be
          applied to reduce employer contributions for all remaining
          Participants in the next limitation year, and each succeeding
          limitation year if necessary; and

               (4)  If a suspense account is in existence at any time during a
          limitation year pursuant to this section, it will not participate in
          the allocation of the trust's investment gains and losses.  If a
          suspense account is in existence at any time during a particular
          limitation year, all amounts in the suspense account must be allocated
          and reallocated to Participants' accounts before any employer or
          Employee contributions may be made to the Plan for that limitation
          year.  Excess amounts may not be distributed to Participants or former
          Participants.

          I.   Combination With Other Plans.  This section applies if, in
          --   ----------------------------                              
     addition to this Plan, the Participant is covered under another qualified
     defined contribution plan maintained by the employer, a welfare benefit
     fund, as defined in Section 419(e) of the Code maintained by the employer,
     or an individual medical account, as defined in Section 415(1)(2) of the
     Code, maintained by the employer, which provides an annual addition as
     defined in subparagraph  8. J.(6), during any limitation year.  The annual
                                 --                                            
     additions which may be credited to a Participant's account under this Plan
     for any such limitation year will not exceed the maximum permissible amount
     reduced by the annual additions credited to a Participant's account under
     the other plans and welfare benefit funds for the same limitation year.  If
     the annual additions with respect to the Participant under other defined
     contribution plans and welfare benefit funds maintained by the employer are
     less than the maximum permissible amount and the employer contribution that
     would otherwise be contributed or allocated to the Participant's account
     under this Plan would cause the annual additions for the limitation year to
     exceed this limitation, the amount contributed or allocated will be reduced
     so that the annual additions under all such plans and funds for the
     limitation year will equal the maximum permissible amount.  If the annual
     additions with respect to the Participant under such other defined
     contribution plans and welfare benefit funds in the aggregate are equal to
     or greater than the maximum permissible amount, no amount will be
     contributed or allocated to the Participant's account under this Plan for
     the limitation year.

          Prior to determining the Participant's actual compensation for the
     limitation year, the employer may determine the maximum permissible amount
     for a Participant in the manner described in subparagraph 8. H.  As soon as
                                                               -- --            
     is administratively feasible after the end of the limitation year, the
     maximum permissible amount for the limitation year will be determined on
     the basis of the Participant's actual compensation for the limitation year.
     If as a result of forfeitures or as a result of exceeding the maximum
     permissible amount, a Participant's annual additions under this Plan and
     such other plans would result in an excess amount for a limitation year,
     the excess amount will be deemed to consist of the annual additions last
     allocated, except that annual additions attributable to a welfare benefit
     fund or individual medical account will be deemed to have been allocated
     first regardless of the actual allocation date.  If an excess amount was
     allocated to a Participant on an allocation date of this Plan which
     coincides with an allocation date of another plan, the excess amount
     attributed to this Plan will be the product of:

               (a)  the total excess amount allocated as of such date, times

               (b)  the ratio of (i) the annual additions allocated to the
          Participant for the limitation year as of such date under this Plan to
          (ii) the total annual additions allocated to the Participant for the
          limitation year as of such date under this and all the other qualified
          defined contribution plans.

                                      -22-
<PAGE>
 
          Any excess amount attributed to this Plan will be disposed in the
     manner described in subparagraph 8. H.

          If the employer maintains, or at any time maintained, a qualified
     defined benefit plan covering any Participant in this Plan, the sum of the
     Participant's defined benefit plan fraction and defined contribution plan
     fraction will not exceed 1.0 in any limitation year.  The annual additions
     which may be credited to the Participant's account under this Plan for any
     limitation year will be reduced or limited by the Trustee in a uniform and
     nondiscriminatory manner in order to effect the foregoing limitation.

          J.   Section 415 Definitions.
          --   ----------------------- 

               (1)  Annual additions:  The sum of the following amounts credited
          to a Participant's account for the limitation year:

                    (a)  employer contributions,

                    (b)  Employee contributions,

                    (c)  forfeitures, and

                    (d)  amounts allocated, after March 31, 1984, to an
               individual medical account, as defined in Section 415(1)(2) of
               the Code, which is part of a pension or annuity plan maintained
               by the employer are treated as annual additions to a defined
               contribution plan.  Also amounts derived from contributions paid
               or accrued after December 31, 1985, in taxable years ending after
               such date, which are attributable to post-retirement medical
               benefits, allocated to the separate account of a key employee, as
               defined in Section 419A(d)(3) of the Code, under a welfare
               benefit fund, as defined in Section 419(e) of the Code,
               maintained by the employer are treated as annual additions to a
               defined contribution plan.

               For this purpose, any excess amount applied under subparagraphs
          8. H. or 8. I. in the limitation year to reduce employer contributions
          -- --    -- --                                                        
          will be considered annual additions for such limitation year.

               (2)  Compensation:  A Participant's Earned Income, wages,
          salaries, and fees for professional services and other amounts
          received for personal services actually rendered in the course of
          employment with the employer maintaining the Plan (including, but not
          limited to, commissions paid salesmen, compensation for services on
          the basis of a percentage of profits, commissions on insurance
          premiums, tips and bonuses), and excluding the following:

                                      -23-
<PAGE>
 
                    (a)  Employer contributions to a plan of deferred
               compensation which are not includible in the Employee's gross
               income for the taxable year in which contributed, or employer
               contributions under a simplified employee pension plan to the
               extent such contributions are deductible by the Employee, or any
               distributions from a plan of deferred compensation;

                    (b)  Amounts realized from the exercise of a nonqualified
               stock option, or when restricted stock (or property) held by the
               Employee either becomes freely transferable or is no longer
               subject to a substantial risk of forfeiture;

                    (c)  Amounts realized from the sale, exchange or other
               disposition of stock acquired under a qualified stock option; and

                    (d)  Other amounts which received special tax benefits, or
               contributions made by the employer (whether or not under a salary
               reduction agreement) towards the purchase of an annuity described
               in Section 403(b) of the Code (whether or not the amounts are
               actually excludible from the gross income of the Employee).

               For purposes of applying the limitations of this article,
          compensation for a limitation year is the compensation actually paid
          or includible in gross income during such limitation year.

               Notwithstanding the preceding sentence, compensation for a
          participant in a defined contribution plan who is Disabled is the
          compensation such participant would have received for the limitation
          year if the Participant had been paid at the rate of compensation paid
          immediately before becoming Disabled; such imputed compensation for
          the Disabled Participant may be taken into account only if the
          Participant is not a Highly Compensated Employee and contributions
          made on behalf of said Participant are nonforfeitable when made.

               (3)  Defined benefit fraction: A fraction, the numerator of which
          is the sum of the Participant's projected annual benefits under all
          the defined benefit plans (whether or not terminated) maintained by
          the employer, and the denominator of which is the lesser of 125
          percent of the dollar limitation determined for the limitation year
          under Sections 415(b) and (d) of the Code or 140 percent of the
          highest average compensation, including any adjustments under Section
          415(b) of the Code.

               (4)  Defined contribution dollar limitation:  $30,000 or if
          greater, one-fourth of the defined benefit dollar limitation set forth
          in Section 415(b)(1) of

                                      -24-
<PAGE>
 
          the Code as in effect for the limitation year.

               (5)  Defined contribution fraction:  A fraction, the numerator of
          which is the sum of the annual additions to the Participant's account
          under all the defined contribution plans (whether or not terminated)
          maintained by the employer for the current and all prior limitation
          years (including the annual additions attributable to the
          Participant's nondeductible employee contributions to all defined
          benefit plans, whether or not terminated, maintained by the employer,
          and the annual additions attributable to all welfare benefit funds, as
          defined in Section 419(e) of the Code, and individual medical
          accounts, as defined in Section 415(1)(2) of the Code, maintained by
          the employer), and the denominator of which is the sum of the maximum
          aggregate amounts for the current and all prior limitation years of
          service with the employer (regardless of whether a defined
          contribution plan was maintained by the employer).  The maximum
          aggregate amount in any limitation year is the lesser of 125 percent
          of the dollar limitation determined under Sections 415(b) and (d) of
          the Code in effect under Section 415(c)(1)(A) of the Code or 35
          percent of the Participant's compensation for such year.

               (6)  Employer:  For purposes of subparagraphs 8. H., 8. I. and 8.
                                                             -- --  -- --     --
          J., employer shall mean the employer that adopts this Plan, and all
          --                                                                 
          members of a controlled group of corporations (as defined in Section
          414(b) of the Code as modified by Section 415(h)), all commonly
          controlled trades or businesses (as defined in Section 414(c) as
          modified by Section 415(h)) or affiliated service groups (as defined
          in Section 414(m)) of which the adopting employer is a part, and any
          other entity required to be aggregated with the employer pursuant to
          regulations under Section 414(o) of the Code.

               (7)  Excess amount:  The excess of the Participant's annual
          additions for the limitation year over the maximum permissible amount.

               (8)  Highest average compensation:  The average compensation for
          the three consecutive Years of Service with the employer that produces
          the highest average.

               (9)  Limitation year:  A calendar year, or the 12-consecutive
          month period elected by the employer pursuant to action of the Board.

               (10) Maximum permissible amount:  The maximum annual addition
          that may be contributed or allocated to a participant's account under
          the Plan for any limitation year shall not exceed the lesser of:

                    (a)  the defined contribution dollar limitation, or

                                      -25-
<PAGE>
 
                    (b)  25 percent of the Participant's compensation for the
               limitation year.

               The compensation limitation referred to in (b) shall not apply to
          any contribution for medical benefits (within the meaning of Section
          401(h) or Section 419A(f)(2) of the Code) which is otherwise treated
          as an annual addition under Section 415(l)(1) or 419A(d)(2) of the
          Code.

               If a short limitation year is created because of an amendment
          changing the limitation year to a different 12-consecutive month
          period, the maximum permissible amount will not exceed the defined
          contribution dollar limitation multiplied by the following fraction:

                 Number of months in the short limitation year
                 ---------------------------------------------
                                      12

               (11)  Projected Annual Benefit:  The annual retirement benefit
          (adjusted to an actuarially equivalent straight life annuity if such
          benefit is expressed in a form other than a straight life annuity) or
          qualified joint and survivor annuity to which the Participant would be
          entitled under the terms of the Plan assuming:

                     (a)  the Participant will continue employment until Normal
               Retirement Age under the Plan (or current age, if later), and

                     (b)  the Participant's compensation for the current
               limitation year and all other relevant factors used to determine
               benefits under the Plan will remain constant for all future
               limitation years.

     9.   Retirement and Severance.
     --   ------------------------ 

          A.   Normal Retirement, Etc.  Upon the attainment by a Participant of
          --   -----------------------                                         
     the Normal Retirement Age of sixty-five (65), such Participant's account
     shall be fully vested and nonforfeitable.  In the event that the employment
     of a Participating Employee shall terminate at any time due to the death or
     Disability of such Participating Employee, such Participant's account shall
     be fully vested and nonforfeitable from and after the date of termination
     of employment.  Payment of benefits under the Plan to or on behalf of said
     Participant shall be made in accordance with the provisions of Paragraph
     10. below.
     ---       

          B.   Vested Benefits; Termination of Employment.  The portion of a
          --   ------------------------------------------                   
     Participating Employee's share in the Trust allocated to the Salary
     Reduction 

                                      -26-
<PAGE>
 
     Contribution Account and the Rollover Contribution Account shall at all
     times be fully and immediately vested in such Employee. This portion,
     together with the vested portion of the Matching Company Contribution
     Account and the Company Discretionary Contribution Account, determined in
     accordance with the schedule set forth below, depending upon such
     Participant's Vesting Years of Service completed to the date of termination
     of employment shall be paid to or on behalf of such Participant at such
     time and in the manner provided under the further terms of the Plan.

          The vesting schedule applicable to a Participant's Matching Company
     Contribution Account and Company Discretionary Contribution Account shall
     be as follows:

<TABLE>

                                                  Vested
          Vesting Years of Service              Percentage
          ------------------------              ----------
          <S>                                   <C> 
          Less than 1 year                         0%
          1 or more, but less than 2              20%
          2 or more, but less than 3              40%
          3 or more, but less than 4              60%
          4 or more, but less than 5              80%
          5 years or more                        100%
</TABLE> 

          Any amount not vested under the foregoing vesting schedule shall
     remain as an unallocated suspense account until the Anniversary Date upon
     which said Participant has incurred five consecutive One-Year Breaks in
     Service, which said amount shall thereupon constitute a forfeiture and
     shall be applied as provided in subparagraph D. hereinbelow.
                                                  --              
     Notwithstanding the foregoing sentence, the amount not vested under the
     above vesting schedule shall constitute a forfeiture as of the time of
     distribution of the vested benefit.  If a Participant terminates employment
     with the Company at a time when his vested account balance is zero, he will
     be deemed to have received a distribution of his entire vested account
     balance upon his termination of employment.

          In the case of a terminated Participating Employee who has incurred
     five consecutive One-Year Breaks in Service, Vesting Years of Service after
     such break shall not be taken into account in determining the vested
     percentage of his account which accrued prior to such five consecutive One-
     Year Breaks in Service.  In the case of a Participating Employee whose
     interest in the Plan has been distributed on termination of participation
     and was not repaid pursuant to the terms of subparagraph C. below, any
                                                              --           
     service after the distribution date will not increase the amount of the
     Participant's non-forfeitable benefit in the Plan as computed at the time
     of distribution.  Separate accounts for the pre-break and post-break
     portions of such person's interest in the Plan 

                                      -27-
<PAGE>
 
     will be maintained, if and to the extent necessary to properly reflect the
     provisions of this subparagraph.

          C.   Repayment of Prior Distributions.  If a Participating Employee
          --   --------------------------------
     who has separated from service with the Company and received a distribution
     under the Plan shall return to the employment of the Company before
     incurring five consecutive One-Year Breaks in Service, any amount
     previously declared as a forfeiture (unadjusted by any later gains or
     losses) shall be reinstated to the Participant's account upon repayment by
     the Participant of the full amount of the distribution (unadjusted by any
     later gains or losses). Such repayment must be made before the Anniversary
     Date ending the Plan Year within which the Participant incurs a fifth
     consecutive One-Year Break in Service. If a Participant who is deemed to
     have received a distribution of his vested account balance because his
     vested account balance was zero returns to the employment of the Company
     before incurring five consecutive One-Year Breaks in Service, any amount
     previously declared as a forfeiture shall be reinstated to the
     Participant's account. Funds needed in any Plan Year to reinstate the
     amount previously forfeited by a re-employed Participant shall be provided
     first by forfeitures occurring during that Plan Year, and second, if
     necessary, by the Company by way of a separate Plan contribution. In such
     event, upon a subsequent termination of employment or retirement, the
     Participant's vested interest shall be determined in accordance with the
     foregoing vesting schedule as if no previous separation from service had
     occurred.

          D.   Treatment of Forfeitures.  The nonvested portion of a
          --   ------------------------                             
     Participant's account under the Plan shall constitute a forfeiture.  Any
     such forfeiture with respect to a Company Discretionary Contribution
     Account shall be reallocated to the accounts of those persons who, on the
     Anniversary Date ending the Plan Year during which the forfeiture occurred
     are eligible to participate in Company Discretionary contributions to the
     Plan for such Plan Year, and shall be allocated in the same manner as
     Company Discretionary contributions to the Plan are allocated pursuant to
     subparagraph 8. G. hereinabove.  Any such forfeiture of a Participant's
                  -- --                                                     
     Matching Company Contribution Account shall be used to reduce the Company's
     Matching Company Contributions to the Plan, and shall not be used to
     increase the benefits of the Participants and Beneficiaries.

     10.  Distribution of Benefits.
     ---  ------------------------ 

          A.   Notice By Company.  The Company shall certify to the Trustee, in
          --   -----------------                                               
     the event of termination of the employment of any Participant, the date of
     such termination.  The Company shall also certify to the Trustee the date
     of death of any Participant.  The Trustee shall rely on such certification
     in determining the extent to which such Participant, or his Beneficiary,
     shall be entitled to benefits under the Plan.

          B.   Form of Payment.  The amount payable to the Participant (or his
          --   ---------------             
     or her

                                      -28-
<PAGE>
 
     Beneficiary) shall be paid in the form of a cash lump sum.

          C.   Timing of Payment.  A Participant who terminates employment after
          --   -----------------                                                
     attainment of the Normal Retirement Age shall receive or commence to
     receive his benefit within 60 days after the Anniversary Date following his
     termination of employment.  A Participant who terminates employment prior
     to his attainment of the Normal Retirement Age shall have the option to
     receive, at his or her election, a distribution of his or her entire
     interest in the form of a cash lump sum as soon as administratively
     feasible after the Participant's termination of employment with the
     Company.  If the Participant's vested interest in the Plan has never
     exceeded $3,500, the entire benefit shall be distributed to the Participant
     in a cash lump sum payment as soon as administratively feasible.  In no
     event shall payments be delayed in violation of Section 401(a)(14) of the
     Code.

          Notwithstanding the foregoing, a Participant's Salary Reduction
     Account shall not be distributed earlier than: (i) termination of
     employment, death, or Disability; (ii) termination of the Plan without
     establishment of a successor plan; (iii) attainment of age 59-1/2; (iv)
     financial hardship as provided in Paragraph 6. above; (v) the sale or other
                                                 --                             
     disposition by the Company of substantially all of its assets used in a
     trade or business to an unrelated entity, but only with respect to
     Employees who continue employment with the acquiring entity; or (vi) the
     sale or other disposition by the Company of its interest in a subsidiary to
     an unrelated entity but only with respect to Employees who continue
     employment with the subsidiary.

          D.   Other Rules for Commencement and Duration of Benefits.  This
          --   -----------------------------------------------------       
     subparagraph only applies to Participant's who remain in the employment of
     the Company beyond the calendar year in which they attain age 70-1/2 and to
     Participant's who are eligible to receive distribution of their benefit in
     a form other than a cash lump sum. The entire interest in the Plan of any
     Participating Employee must be, or commence to be, distributed before April
     1 of the calendar year following the calendar year in which the
     Participating Employee attains age 70-1/2. Benefits distributed hereunder
     shall be distributed over a period not to exceed the life of the
     Participant, the life of the Participant and his designated Beneficiary,
     the life expectancy of the Participating Employee, or the joint life
     expectancy of the Participating Employee and his designated Beneficiary. If
     the Participant's entire interest is to be distributed in a form other than
     a lump sum, then the amount to be distributed each year must be at least
     equal in amount to the quotient obtained by dividing the Participant's
     entire interest by the lesser of (i) the applicable life expectancy (ii) if
     the Participant's spouse is not the designated Beneficiary, the applicable
     divisor determined from the table set forth in Q&A-4 of Section 
     1.401(a)(9)-2 of the Proposed Regulations or such other successor
     regulation or publication which may be announced by the Secretary of the
     Treasury. For purposes of this computation, the life expectancy of the
     Participant may be recalculated no more frequently than annually, but the
     life expectancy of a nonspouse Beneficiary may not be recalculated.

          E.   Death Benefits; Beneficiary Designation; Distribution of Death
          --   --------------------------------------------------------------
     Benefits.  In the event of the death of a Participant in the Plan, his
     --------                                                              
     accrued benefit shall be paid in full as soon as practicable to his
     surviving spouse, as his Beneficiary.  Notwithstanding the foregoing,
     however, a Participant may designate a Beneficiary other than the
     Participant's spouse if (1) the spouse has waived his or her right to be
     the Participant's Beneficiary in accordance with this subparagraph; or (2)
     the Participant has no spouse; or (3) the spouse cannot be located.

          In such event, the designation of a Beneficiary shall be made on a
     form satisfactory to the Company.  A Participant may at any time revoke his
     designation of a Beneficiary or change his Beneficiary by filing written
     notice of such revocation or change with the Company.  However, the
     Participant's spouse must again consent in writing to any such change or
     revocation.  Any consent by the Participant's spouse to waive any rights to
     the death benefit must be in writing, must acknowledge the effect of such
     waiver, and be witnessed by a Plan representative or a notary public.  In
     the event that no valid designation of Beneficiary exists at the time of
     the Participant's death, and the Participant has no surviving spouse, the
     death benefit shall be payable to his estate.

          In the event that payments are made to a Beneficiary, on account of
     the death of a Participant (or the death of a Participant's spouse), the
     entire interest of the Participant shall be distributed to such Beneficiary
     within five years after said death.

          F.   Segregated Accounts.  Amounts credited to the accounts of
          --   -------------------                                      
     Participants whose employment has terminated or Beneficiaries which are not
     paid out may be held with other assets of the Trust or may be held
     separately from the assets held for the benefit of other Participating
     Employees.  If so segregated, the Trustee shall invest such segregated
     accounts in savings accounts, certificates of deposit, Treasury bills,
     bonds, or similar interest-bearing investments, regardless of the
     investment policy adopted by the Trustee respecting the balance of the
     Trust assets.  In so doing, the Trustee shall not discriminate in favor of
     one or some retired Employees or Beneficiaries as against one or some other
     retired Employees or Beneficiaries.  Each such payee shall be credited or
     charged with appropriate adjustments for earnings, losses, and revaluations
     of the segregated amount being held for his benefit; all such adjustments
     shall be made as of each Anniversary Date, in the same manner as
     adjustments to other assets of the Trust.  Nothing in this paragraph,
     however, shall entitle such payee to share in any Company contributions to
     the Trust in which he would not otherwise be entitled to share under the
     provisions of this Agreement.

          G.   Location of Participant or Beneficiary Unknown. In the event that
          --   ----------------------------------------------
     all, or any portion, of the distribution payable to a Participant or his
     Beneficiary hereunder shall, at the expiration of five (5) years after it
     shall become payable, remain unpaid solely by reason of the inability of
     the Administrator, after sending a registered letter, return receipt

                                      -30-
<PAGE>
 
     requested, to the last known address, and after further diligent effort, to
     ascertain the whereabouts of such Participant or his Beneficiary, the
     amount so distributable shall be reallocated in the same manner as
     forfeitures are allocated pursuant to subparagraph 9. D. hereinabove.  In
                                                        -- --                 
     the event a Participant or Beneficiary is located subsequent to his benefit
     being reallocated, such benefit shall be restored.

          H.   Special Distribution Rules Applicable to Qualified Domestic
          --   -----------------------------------------------------------
     Relations Order.  In the event that all, or any portion of the amounts
     ---------------                                                       
     credited to the accounts of a Participant are required to be paid to an
     alternate payee in accordance with the terms of any Qualified Domestic
     Relations Order ("QDRO"), as that term is defined in Paragraph 12. below,
                                                                    ---       
     the Trustee shall distribute to such designated alternate payee all amounts
     required under the QDRO regardless of whether the Participant would be
     entitled to a distribution of his account by virtue of termination of
     employment or attainment of retirement age.  The alternate payee under the
     QDRO shall have the option to receive, at his or her election, the entire
     amount required by the QDRO in the form of a cash lump sum as soon as
     administratively feasible after the Company's receipt and verification of
     the QDRO.

          I.   Direct Rollovers.  This subparagraph applies to distributions
          --   ----------------             
     made on or after January 1, 1993. Notwithstanding any provision of the Plan
     to the contrary that would otherwise limit a distributee's election under
     this subparagraph, a distributee may elect, at the time and in the manner
     prescribed by the Plan Administrator, to have any portion of an eligible
     rollover distribution paid directly to an eligible retirement plan
     specified by the distributee in a direct rollover.

          For purposes of this Subparagraph 8.I., the following definitions
                                            ----                           
     shall apply:

               (1)  Eligible rollover distribution:  An eligible rollover
          distribution is any distribution of all or any portion of the balance
          to the credit of the distributee, except that an eligible rollover
          distribution does not include:  any distribution that is one of a
          series of substantially equal periodic payments (not less frequently
          than annually) made for the life (or life expectancy) of the
          distributee or the joint lives (or joint life expectancies) of the
          distributee and the distributee's designated beneficiary, or for a
          specified period of ten years or more; any distribution to the extent
          such distribution is required under Section 401(a)(9) of the Code; and
          the portion of any distribution that is not includible in gross income
          (determined without regard to the exclusion of net unrealized
          appreciation with respect to employer securities).

               (2)  Eligible retirement plan:  An eligible retirement plan is an
          individual retirement account described in Section 408(a) of the Code,
          an individual retirement annuity described in Section 408(b) of the
          Code, an annuity 

                                      -31-
<PAGE>
 
          plan described in Section 403(a) of the Code, or a qualified trust
          described in Section 401(a) of the Code, that accepts the
          distributee's eligible rollover distribution. However, in the case of
          an eligible rollover distribution to the surviving spouse, an eligible
          retirement plan is an individual retirement account or individual
          retirement annuity.

               (3)  Distributee:  A distributee includes an Employee or former
          Employee.  In addition, the Employee's or former Employee's surviving
          spouse and the Employee's or former Employee's spouse or former spouse
          who is the alternate payee under a qualified domestic relations order,
          as defined in Section 414(p) of the Code. are distributees with regard
          to the interest of the spouse or former spouse.

               (4)  Direct rollover:  A direct rollover is a payment by the Plan
          to the eligible retirement plan specified by the distributee.

     11.  Loans to Participating Employees.
     ---  -------------------------------- 

     The Trustee shall have the power to make loans from the Trust to all
Participating Employees and Beneficiaries (who are also parties in interest as
defined in ERISA) in accordance with the terms of this Paragraph 11.  All such
                                                                 ---          
loans will be administered by the Plan Administrator.  All loan applications
will be submitted to the Plan Administrator.  The maximum amount of any such
loan, when combined with all existing loans to the Participant from the Plan,
all other plans of the Employer, and any plan maintained by an employer
described in subsections (b), (c), (m) and/or (o) of Section 414 of the Code,
shall not exceed the lesser of:  (i) $50,000 (reduced by the excess of the
highest outstanding loan balance from the Plan and other plans maintained by the
Company, during the period of one year ending on the day before the date of the
loan under consideration, over the outstanding balance of all such loans on the
date of the loan under consideration), or (ii) one-half of the nonforfeitable
account balance of the Employee under such plan or plans.  The minimum amount of
any such loan shall be $1,000.  Each such loan shall be repayable, by its terms,
within five years of the date of the loan; provided, however, that a loan used
to acquire a dwelling unit which within a reasonable time is to be used as the
principal residence of the Participant may be for a term in excess of five
years.  All such loans may be secured by:  (i) one-half of the Participant's
nonforfeitable account, and/or by (ii) such other security as deemed necessary
under the circumstances by the Plan Administrator for the full protection of the
Plan and Trust.  All loans shall be made at a rate of interest not less than the
then prevailing rate of interest in the Duluth, Minnesota, area which would be
available under the circumstances from an institutional lender.  Each loan shall
be evidenced by a promissory note, executed by the borrowing Participant,
requiring level amortization of such loan with payments of principal and
interest at stated intervals not less frequently than quarterly.  The failure of
a Participant to repay a loan in accordance with the terms of the promissory
note within ten (10) days after written demand by the Plan Administrator

                                      -32-
<PAGE>
 
shall constitute a default. Upon default, the Trustee may accelerate the
Participant's obligation to repay the loan. If said loan is not then paid in
full, the Trustee may satisfy said loan by treating the amount of the
outstanding balance due under said loan as a distribution to the Participant of
said amount at the earliest time that such amount may be distributable to the
Participant under the terms of the Plan. If the loan is secured by additional
security, the Trustee may execute on the security in accordance with local law.
The Trustee may also take such other steps as permitted by law to protect the
Plan Assets. The outstanding principal balance due on a loan shall be offset
against and shall reduce any amounts otherwise payable to the Participant under
the Plan. The Trustee is authorized to follow instructions given by the Plan
Administrator in connection with all loans granted pursuant to this Paragraph
11.  The Plan Administrator may adopt such other rules and procedures as it
- ---                                                                        
deems appropriate to administer the granting of loans and/or to comply with all
applicable government regulations.

     A Participant must obtain the consent of his or her spouse, if any, to use
of the account balance as security for the loan.  Spousal consent shall be
obtained no earlier than the beginning of the 90-day period that ends on the
date on which the loan is to be so secured.  The consent must be in writing,
must acknowledge the effect of the loan, and must be witnessed by a plan
representative or notary public.  Such consent shall thereafter be binding with
respect to the consenting spouse or any subsequent spouse with respect to that
loan.  A new consent shall be required if the account balance is used for
renegotiation, extension, renewal, or other revision of the loan.

     12.  Spendthrift Clause.
     ---  ------------------ 

     Except as otherwise provided in this paragraph, the rights of a Participant
or Beneficiary to receive payments or benefits hereunder shall not be subject to
alienation or assignment, and shall not be subject to anticipation, encumbrance
or claims of creditors.  Notwithstanding the foregoing, the Plan shall pay
benefits in accordance with the terms of any Qualified Domestic Relations Order,
provided that such Order (i) does not require the Plan to provide any type or
form of benefits, or any option, that is not otherwise provided hereunder, (ii)
does not require the Plan to provide increased benefits, and (iii) does not
require the payment of benefits to an alternate payee which are required to be
paid to another alternate payee under another order previously determined to be
a Qualified Domestic Relations Order.  For purposes of the preceding sentence, a
"Domestic Relations Order" shall mean any judgment, decree or order (including
approval of a property settlement agreement) which relates to the provision of
child support, alimony payments, or marital property rights to a spouse, former
spouse, child, or other dependent of a Participant and is made pursuant to a
state domestic relations law.  "Qualified Domestic Relations Order" shall mean a
Domestic Relations Order which creates or recognizes the existence of an
alternate payee's right to, or assigns to an alternate payee the right to,
receive all or a portion of the benefits payable with respect to a Participant
under this Plan and which clearly  specifies (i) the name and the last known
mailing address of the Participant and each 

                                      -33-
<PAGE>
 
alternate payee covered by the Order, (ii) the amount or percentage of the
Participant's benefits to be paid by the Plan to each such alternate payee, or
the manner in which such amount or percentage is to be determined, (iii) the
number of payments or period to which such Order applies, and (iv) each plan to
which such Order applies. A distribution by the estate of a deceased Participant
or Beneficiary to an heir or legatee of a right to receive payments hereunder
shall not be deemed an alienation, assignment or anticipation for the purposes
of this Paragraph 12.
                  ---

     13.  Administration of Trust.
     ---  ----------------------- 

     In administering this Plan and Trust, the Trustee and the Company shall
administer the same for the benefit of all Participating Employees and
Beneficiaries as herein provided, without discrimination in favor of one or some
Participating Employees or Beneficiaries as against one or some other
Participating Employees or Beneficiaries.

     Whenever action is required by the Company hereunder, the same may be taken
by any individual designated as agent for the purpose.  The Company shall notify
the Trustee of any change of agent.  The Trustee shall be entitled to rely upon
information or instructions received from the agent of the Company whose
authority to act was last certified by the Trustee.  Any information or
instruction from the Company to the Trustee shall be in writing and shall be
effective upon delivery to the Trustee.  The Trustee shall be under no duty or
responsibility to inquire into the acts or omissions of the Company, nor shall
the Trustee have any liability therefor.  Should it become necessary to perform
some act hereunder and there is neither direction in this Plan nor information
nor instructions from the Company on file with the Trustee relating thereto, and
no such information or instructions can be obtained after reasonable inquiry,
the Trustee shall have full power and authority to act in the Trustee's
discretion, consistently with the purpose of this Plan; and in so acting or in
following any instructions from the Company, the Trustee shall be fully
protected and shall be absolved from all liability except from fraud or bad
faith.

     The duties, powers and responsibilities of the Trustee shall be limited as
specifically provided herein.  No person serving as a Trustee hereunder shall be
liable or responsible to anyone for any matter or thing whatsoever, provided
only that he has acted in good faith.

     The Trustee in performing any act hereunder shall be entitled to rely upon
any affidavit, certificate, letter, notice, telegram or other paper or document
believed by the Trustee to be genuine and upon any information or evidence
believed by the Trustee to be sufficient; and the Trustee shall be protected in
all payments hereunder if made in good faith and without actual knowledge of the
happening of an event or a change in conditions which would affect such
payments.

                                      -34-
<PAGE>
 
     The Trustee shall make any sale, investment or reinvestment of the Trust
property or any part thereof which the Company may from time to time direct, and
if such direction be given, the Trustee shall have no obligation with respect
thereto except for failure to carry out such direction.  Without limiting the
generality of the foregoing, the Company may direct the investment of Trust
funds in stock and/or obligations of the Company and in stock and/or obligations
of the Trustee (if a corporate Trustee then be acting in such capacity under
this Trust).  The Trustee shall have no liability for any depreciation or loss
with respect to any property acquired by the Trustee pursuant to such direction,
and shall have no duty to review or to make recommendations with respect
thereto.

     14.  Trustee's Administrative Powers.
     ---  ------------------------------- 

     The Trustee shall receive, hold, invest and reinvest contributions to the
Trust fund and shall make disbursements from the Trust fund pursuant to the
terms of this Plan.  Subject to the consent of the Trustee, the Company shall
have the right to make its contributions hereunder in property to the Trustee.
The Trustee shall make payments from the Trust fund only to such persons, in
such manner, at such times, and in such amounts as may be specified in written
directions from the Company and not otherwise, and the Trustee shall be fully
protected in making payments under the direction of the Company.  For purposes
of accounting and valuation, the records of the Trust shall be maintained on a
cash receipts and disbursements basis.  The Trustee from time to time shall
capitalize unexpended income and add the same to the principal of the Trust.

     Subject only to such instructions, rules and restrictions as may from time
to time be adopted by the Company and communicated to the Trustee, the Trustee
shall have the following powers and rights in addition to those invested in the
Trustee by law:

          (a)  Investment Powers.  To hold, manage and control the assets of the
               -----------------                                                
     Trust, during the continuance of the Trust.  The Trustee shall have full
     power without any court order to improve, lease for any term irrespective
     of the duration of the Trust, rent, sell, exchange, hold, control, invest
     and reinvest the same in such manner and upon such terms as the Trustee
     deems best, including (without limitation of these powers) the power to
     purchase shares in investment trusts and stock in investment corporation,
     irrespective of any statutes or rules or practices of courts now or
     hereafter in force limiting the investments of trust companies or trustees
     generally, with full power to convert realty into personalty and personalty
     into realty.  The Trustee hereunder shall not be required to dispose of any
     property held hereunder in order to diversify the investments of the Trust
     or because such holdings are of a kind not ordinarily considered as proper
     investments for trust estates; nor shall the Trustee be precluded from
     acquiring property which results in a nondiversification of the investments
     of the Trust or which is of a kind not ordinarily considered as proper
     investments for trust estates; therefore, the Trustee is granted the 

                                      -35-
<PAGE>
 
     right to retain property so long as the Trustee shall deem such investments
     reasonably sound, and to acquire such property as the Trustee deems to be a
     reasonably sound investment, regardless of the proportion of the Trust
     which it represents and regardless of whether it is of a type ordinarily
     deemed proper for trust investments. The Trustee is authorized to hold cash
     uninvested at any time and from time to time. No purchaser from nor lender
     to the Trustee need see to the application of the purchase or loan money to
     the purposes of the Trust, but the receipt of the Trustee shall be a
     complete discharge to any such person. The Trustee acting hereunder shall
     not be held responsible for any loss sustained by the Trust through any
     error of judgment made in good faith, but shall be liable only for the
     Trustee's own willful misconduct. The Trustee hereunder shall not be
     personally liable upon any contract of indebtedness of or claim against the
     Trust or upon a mortgage, trust deed, note or other instrument executed
     under the provisions of this Plan.

          (b)  Borrowing.  To borrow money from the Trustee or others, upon such
               ---------                                                        
     terms and conditions, at any time or times, and for such purposes of the
     Trust as the Trustee may deem proper or desirable provided that such
     borrowing does not result in a prohibited transaction under Code Section
     4975(c).  For sums borrowed, the Trustee may issue the Trustee's promissory
     notes as Trustee and secure the payment thereof by mortgaging or pledging
     any part or all of the Trust assets.

          (c)  Holding and Transferring Real Estate.  To take and hold title to
               ------------------------------------                            
     real estate or interests therein in the Trustee's name or in the name of
     the Trustee's nominee without disclosing the Trust; and in accepting title
     to the real estate, neither the Trustee nor the Trustee's nominee shall be
     held to have assumed the payment of any encumbrances thereon, nor any
     responsibility as to the validity of the title conveyed to or held by the
     Trustee or the Trustee's nominee.  All conveyances executed and delivered
     by the Trustee or the Trustee's nominee shall be without covenants of
     warranty except as against the Trustee's own acts.

          (d)  Voting and Related Powers.  To vote any stocks, bonds, or other
               -------------------------                                      
     securities, to give general or special powers of attorney with or without
     power of substitution; to exercise any conversion privileges, subscription
     rights or other options and to make any payments incidental thereto; to
     consent to or otherwise participate in corporate reorganizations or other
     changes affecting corporate securities and to delegate discretionary powers
     and to pay any assessments or charges in connection therewith; and
     generally to exercise any of the powers of an owner with respect to stocks,
     bonds, securities or other property held in the Trust.

          (e)  Claims by or Against the Trust.  To sue or defend in any suit or
               ------------------------------                                  
     legal proceedings by or against the Trust.  The Trustee shall have full
     power in the Trustee's discretion to compound, compromise and adjust all
     claims and demands in favor of or 

                                      -36-
<PAGE>
 
     against the Trust upon such terms as the Trustee may deem best. In the
     administration of the Trust, the Trustee shall not be obligated to take any
     action which may subject the Trustee to any expense or liability unless the
     Trustee is first indemnified to the Trustee's satisfaction for all expenses
     and liabilities, including attorneys' fees, which the Trustee may incur in
     connection with such action.

          (f)  Nominee.  To register any investment held in the Trust in the
               -------                                                      
     Trustee's own name or in the name of a nominee and to hold any investment
     in bearer form; provided, however, that the books and records of the
     Trustee shall at all times show that all such investments are part of the
     Trust fund, and provided further that such registration or holding shall
     neither increase nor decrease the liability of the Trustee.

          (g)  Employment of Agents.  To employ such agents, attorneys-in-fact,
               --------------------                                            
     experts and investment and legal counsel, including any firm or corporation
     with which the Trustee may be associated as a partner, director,
     stockholder or otherwise, and to delegate discretionary powers to or to
     rely upon information or advice furnished by such agents, attorneys-in-
     fact, experts or counsel.

          (h)  Execution of Instruments.  To execute and deliver any and all
               ------------------------                                     
     documents of transfer and conveyance and any and all other instruments that
     may be necessary or appropriate to carry out the powers herein granted, and
     to perform any and all acts that may be necessary or convenient in the
     proper administration of the Trust.

          (i)  Collective Investment Trust.  To commingle assets of the Trust
               ---------------------------                                   
     with assets of other trusts, which in each case form a part of a pension or
     profit-sharing plan qualified under the Code and constitute an exempt trust
     within the meaning of the Code, (i) through the medium of any collective
     investment trust for employee benefit trusts established and maintained by
     any bank, or, to the extent permitted by law, or (ii) through the medium of
     any collective investment trust for employee benefit trusts established and
     maintained by any trust company.  To the extent of the equitable share of
     this Trust in any such investment trust, the instrument establishing such
     investment trust, as the same has been or may be amended, and the trust
     maintained thereunder, shall be deemed a part of this Plan and Trust as if
     fully set forth herein.

          (j)  Necessary Acts.  To do all acts whether or not expressly
               --------------                                          
     authorized which may be necessary or proper for the protection of the
     property held hereunder or for the carrying out of any duty under this Plan
     or under the Trust fund.

     15.  Holding of Trust Assets.
     ---  ----------------------- 

     Except as otherwise provided hereinabove, all the assets in the Trust shall
be held 

                                      -37-
<PAGE>
 
collectively for all the Participants and Beneficiaries with no physical
division thereof until such time as distribution is actually made by the
Trustee.

     16.  Nonliability of Successor Trustee.
     ---  --------------------------------- 

     Each successor Trustee may accept as complete and correct and may rely upon
any accounting which shall have been made by or on behalf of any Trustee
hereunder prior to the date upon which such successor Trustee shall have
qualified as a Trustee under this instrument, and may rely upon any statement or
representation made by any Trustee then or theretofore acting hereunder as to
the assets comprising the Trust or as to any other fact bearing upon the prior
administration of the Trust created herein; and such successor Trustee shall not
be subject to any liability by reason of having accepted and relied upon such
accounting, statement or representation in case it is subsequently established
that the same was incomplete, inaccurate or untrue.  No successor Trustee
hereunder shall be subject to any liability or responsibility with respect to
any act or omission of any other Trustee nor shall any successor Trustee have
any duty to enforce or to seek to enforce any claims of any kind against any
predecessor Trustee on account of or in connection with any act or omission of
any Trustee hereunder.

     17.  Decision of Majority of Trustees to Govern.
     ---  ------------------------------------------ 

     Except as otherwise expressly provided, when there are three Trustees
authorized to act in any particular, the agreement of a majority of the Trustees
shall be required, and when there are two Trustees authorized to act in any
particular, the agreement of both Trustees shall be required.  Each Trustee
shall be liable only for his own acts in the administration of this Trust.  No
Trustee shall be in any way or to any extent liable to the Participants,
Beneficiaries or others for anything done hereunder by his Co-Trustee to which
he did not actively consent or of which he did not actively approve.

     18.  Accounts.
     ---  -------- 

     The Trustee shall keep accurate and detailed accounts of all investments,
receipts and disbursements and other transactions hereunder, and all accounts,
books and records relating thereto shall be open to inspection by any person
designated by the Board of Directors of the Company at all reasonable times.
Not later than one hundred twenty (120) days after the end of each Plan Year,
and within sixty (60) days after the effective date of the removal or
resignation of a Trustee, the Trustee shall file with the Company a written
report setting forth all investments, receipts, disbursements, and other
transactions effected by the Trustee from the date of the prior such report to
the close of such Plan Year, or the date of removal or resignation of a Trustee,
as the case may be. Such report shall contain an exact description of all
securities and investments held at the close of such Plan Year or the effective
date of such removal or

                                      -38-
<PAGE>
 
resignation of a Trustee, as the case may be, and the cost of each item thereof,
as carried on the books of the Trustee. Upon the expiration of ninety (90) days
from the date of filing such report, the Trustee, including a Trustee who
resigned or was removed, shall be forever released and discharged from any
liability or accountability to anyone as respects the propriety of the Trustee's
acts or transactions shown in such report, except with respect to any such acts
or transactions as to which the Company shall within such 90-day period file
with the Trustee a written statement claiming fraud or bad faith on the part of
the Trustee; and neither the Company nor any other person shall have the right
to demand or be entitled to any further or different accounting by the Trustee.

     19.  Removal or Resignation of Trustee.
     ---  --------------------------------- 

     Any Trustee hereunder may be removed by resolution of the Board of
Directors of the Company upon delivery to such person of a certified copy of
such resolution of removal.  Any Trustee hereunder may resign as Trustee, upon
written notice to that effect, delivered to the Company.  Such removal or
resignation shall become effective upon the date specified in such resolution or
such notice, as the case may be, which shall be not less than fifteen (15) days
subsequent to the delivery of such certified copy of resolution or such notice.
In the event of the removal, resignation, death or inability to serve of any
Trustee hereunder, a successor shall be appointed by resolution of the Board, a
certified copy of which resolution shall be delivered to such successor.  In the
event of the removal, resignation, death or inability to serve of any Trustee
hereunder after the Company shall have gone out of business or  ceased to exist
or been dissolved, voluntarily or involuntarily, or had a receiver or trustee in
bankruptcy appointed, a successor may be appointed by election by a majority in
interest of the Participants and Beneficiaries then having an interest in the
Trust.  A successor Trustee, upon accepting such appointment, shall become
vested with the same powers, duties, privileges, and immunities as if such
Trustee had been originally named in this Plan as a Trustee.  In case of the
removal, resignation, death or inability to serve of a Trustee, said Trustee or
his personal representative shall forthwith turn over to the remaining or
succeeding Trustees all accounts and records in such Trustee's possession, and
shall execute such instruments as may be necessary to terminate such
trusteeship.  No bond shall be required of the Trustee named in this Plan or any
of the Trustee's successors.

     20.  Allocation of Responsibilities.
     ---  ------------------------------ 

          A.   Administrative Responsibilities.  The Company is the Named
          --   -------------------------------                           
     Fiduciary which has the authority to control and manage the operation and
     administration of the Plan.  The Company shall make such rules,
     regulations, interpretations, and shall take such other actions to
     administer the Plan as the Company may deem appropriate.  In administering
     the Plan, the Company shall act in a nondiscriminatory manner with 

                                      -39-
<PAGE>
 
     respect to Plan Participants and Beneficiaries, and shall at all times
     discharge its duties with respect to the Plan in accordance with applicable
     fiduciary standards.

          B.   Management of Plan Assets.  The Company is the Named Fiduciary
          --   -------------------------                                     
     with respect to control over and management of the Plan's assets only to
     the extent that it (i) shall appoint one or more Trustees to hold the
     assets of the Plan in trust, (ii) shall appoint one or more Investment
     Managers for any Plan assets and enter into an investment management
     agreement with each Investment Manager it appoints, and (iii) shall
     exercise its authority to direct the sale, investment or reinvestment of
     Plan assets in accordance with Paragraph 13. hereinabove.  The Company
                                              ---                          
     shall be responsible for diversifying the investments of the Plan only to
     the extent that said authority to direct investments is exercised, and the
     Trustee and the Investment Managers, if any, shall be responsible for
     diversifying the specific investments in accounts under their management.

          C.   Trustee and Investment Managers.  The Trustee shall have the
          --   -------------------------------                             
     exclusive authority and discretion to control and manage the assets of the
     Plan held in trust by it, and shall be the Named Fiduciary with respect to
     such control and management, except to the extent that the Company
     exercises its authority to direct investment of the Plan's assets, or that
     the authority to manage such assets is allocated by the Company to one or
     more Investment Managers.  Each Investment Manager appointed by the Company
     shall have the authority to manage, including the power to acquire and
     dispose of, such assets of the Plan as are assigned to it by the Company.

          D.   Delegation of Fiduciary Responsibilities.  Except as otherwise
          --   ----------------------------------------                      
     expressly stated herein, the Company shall not allocate or delegate to any
     other person any of its duties and responsibilities hereunder.  The duties
     and responsibilities of the Company shall be carried out by the Company's
     Directors and officers, acting on behalf of and in the name of the Company
     in their capacities as such, and not as individual fiduciaries.  The
     Company is specifically prohibited from designating any Director or officer
     of the Company as a fiduciary and from allocating or delegating to any such
     person any of the fiduciary responsibilities of the Company.

     21.  Amendments.
     ---  ---------- 

     The Company reserves the right by action of its Board of Directors to amend
this Plan at any time without the consent of the Trustee, but no such amendment
shall cause or permit any portion of the corpus or income of the Trust to revert
to or become the property of or be used for the benefit of the Company.  Any
amendment which is necessary to bring this Trust into conformity with government
laws or regulations in order to qualify the Plan and Trust for tax exemption may
be made retroactively.  No amendment to this Plan may be made which would result
in a cutback of vested rights or rights to accrued benefits as provided in
Section 

                                      -40-
<PAGE>
 
411(a)(10)(A) or 411(d)(6) of the Code. In the event that the vesting schedule,
if any, set forth in the Plan is amended, each Participant who has completed at
least three (3) Years of Service may elect to have his accrued benefit
determined under the vesting schedule in effect prior to the amendment.

     22.  Termination of Contributions.
     ---  ---------------------------- 

     The Company has established this Plan with the bona fide intention and
expectation that from year to year it will be able to and will deem it advisable
to make its contributions as herein provided.  However, the Company realizes
that circumstances not now foreseen or circumstances beyond its control may make
it either impossible or inadvisable to continue to make its contributions as
herein provided.  In the event the Company decides it is impossible or
inadvisable for it to continue to make its contributions as herein provided, the
Company shall have the right to terminate its contributions.

     In the event of complete termination of contributions by the Company, with
or without formal action by the Company, the Company shall make no further
contributions under the Plan, the Plan and Trust shall remain in existence, and
all the provisions of the Plan and Trust shall remain in force which are
necessary in the opinion of the Trustee, other than the provisions for
contributions by the Company and any provisions requiring forfeiture of a
Participating Employee's share in the Trust (the shares in the Trust of each
Participating Employee shall become fully vested in such Participant, regardless
of the length of his employment or his participation, upon such termination of
contributions); and all of the assets in the Trust on the date specified in such
resolutions shall be held, administered and distributed by the Trustee in the
manner provided herein.

     23.  Termination of Trust.
     ---  -------------------- 

     In the event that the Company's contributions to the Trust have been
terminated completely in accordance with the provisions of Paragraph 22. above,
                                                                     ---       
the Board shall also have the power to terminate the Plan and Trust completely
by appropriate resolutions specifying the date of such termination, certified
copies of which shall be delivered to the Trustee.  Upon a complete or partial
termination of the Plan and Trust, with or without formal action by the Company,
any provision requiring forfeiture of the share in the Trust of a Participating
Employee affected by such termination shall become void, and the share in the
Trust of each such Participating Employee shall become fully vested in him.
After payment of all expenses and after adjustment of Participants' and
Beneficiaries' shares for expenses, profits, losses and any other adjustments
necessary to reflect accurately such shares in the Trust in accordance with the
provisions hereof, there shall be paid to each Participant and each Beneficiary
the amount of his share in the Trust, in accordance with the further terms of
this Plan.

                                      -41-
<PAGE>
 
     24.  Merger or Consolidation of Plan, Transfer of Plan Assets.
     ---  ------------------------------------------------- ------ 

     In the event of any merger or consolidation with, or transfer of assets and
liabilities to, any other plan, provision shall be made to the effect that each
Participant and Beneficiary in this Plan will be entitled, after the merger,
consolidation or transfer, to a benefit equal to or greater than the benefit to
which he would have been entitled under this Plan, immediately prior to said
merger, consolidation or transfer, as if the Plan had terminated at such time.

     25.  Top-Heavy Provisions.
     ---  -------------------- 

          A.   Determination of Top-Heavy Status.  As of each determination
          --   --------------------------------- 
     date, the Company shall compute the aggregate amounts allocated to the
     accounts of all "key employees" of the Company. The term "key employee"
     shall mean any Employee, former Employee, or beneficiary thereof who, at
     any time during the Plan Year or any of the four preceding Plan Years, is
     or was (i) an officer of the Employer having an annual Compensation greater
     than fifty percent (50%) of the dollar limitation then in effect under
     Section 415(b)(1)(A) of the Code, (ii) one of the ten Employees having an
     annual Compensation greater than the dollar limitation then in effect under
     Section 415(c)(1)(A) of the Code and owning (or considered as owning within
     the meaning of Section 318 of the Code) the largest interests in the
     Company, (iii) a five percent (5%) owner of the Company or (iv) a one
     percent (1%) owner of the Company who has annual Compensation from the
     Company in excess of $150,000. For purposes of determining percentage
     ownership in the foregoing sentence, the rules of Section 416(i)(1)(B) of
     the Code shall apply and the rules of Sections 414(b), (c), and (m) shall
     not apply. If the aggregate amount allocated to the accounts of all key
     employees exceeds sixty percent (60%) of the aggregate amount allocated to
     the accounts of all Participants, then the Plan will be deemed to be top-
     heavy for the Plan Year next following such Anniversary Date (and in the
     case of the initial Plan Year, for the Plan Year ending with such
     Anniversary Date). For purposes of determining the aggregate amounts
     allocated to the accounts of Participants, there shall be added any amount
     of Company contributions required to be made for the Plan Year ending on
     the determination date (unless this Plan is not subject to the minimum
     funding requirements of Section 412 of the Code). The present value of
     accrued benefits shall be determined based upon the interest and mortality
     rates specified in the defined benefit plan. The account balances
     attributable to a Participant who has not performed any services for the
     Company at any time during the five-year period ending on any determination
     date shall be disregarded. For purposes of making the above determination,
     there shall be considered (i) all other qualified plans of the Company in
     which a key employee is a participant, (ii) all other plans which enable
     this Plan or plans described in (i) above to meet the requirements of
     Sections 401(a)(4) or 410 of the Code, and (iii) all other qualified plans
     which may have been terminated but which were

                                      -42-
<PAGE>
 
     maintained by the Employer within the five-year period ending on the
     determination date. There shall also be considered any distributions made
     with respect to any Participant within a five-year period ending on the
     determination date. At the option of the Company, any other qualified plans
     maintained by it may be included in the group of plans for purposes of
     determining the top-heavy status of the Plan, provided that the group of
     plans would continue to meet the requirements of Sections 401(a)(4) and 410
     of the Code with such plans which are added at the option of the Company
     being taken into account. If any plans of the Company are aggregated with
     this Plan as described in the preceding sentence, this Plan shall be deemed
     to be top-heavy only if the aggregate present value of accrued benefits of
     key employees in the aggregated group of plans exceeds 60 percent of the
     aggregate present value of accrued benefits of all employees in the
     aggregated group of plans. For purposes of determining present value of
     accrued benefits, the rules of Section 416(g) shall apply. Accrued benefits
     shall be determined under the method which is used for accrual purposes for
     all plans of the Company, or if there is no such method, then under the
     slowest accrual rate permitted under Section 411(b)(1)(C) of the Code.
     Determination date shall mean the last day of the preceding Plan Year.
     However, for the first Plan Year the determination date shall be the last
     day of that year. For purposes of determining whether an Employee is a key
     employee, "Compensation" shall mean compensation as defined in Section
     415(c)(3) of the Code, but including Salary Reduction Contributions made to
     this Plan.

          B.   Minimum Allocations.  For each Plan Year that the Plan is top-
          --   -------------------                                          
     heavy, there shall be allocated to the account of each Participant who is
     not a key employee and who is employed by the Company on the last day of
     the Plan Year, irrespective of whether he has completed 1,000 Hours of
     Service with the Company during the Plan Year, an amount not less than
     three percent (3%) of each such Participant's W-2 Compensation (without
     taking into account Social Security and similar contributions and
     benefits).  Notwithstanding the foregoing, if the contribution for any Plan
     Year made by the Company is less than three percent (3%) of the aggregate
     W-2 Compensation of all Participants, then the amount allocable to each
     nonkey employee shall be such lesser percentage.  If the Company maintains
     both a defined contribution plan and a defined benefit plan with a nonkey
     employee who participates, or could participate in both plans, then there
     shall be allocated to the account of each Participant who otherwise would
     be entitled to receive a minimum allocation as described above an amount
     not less than five percent (5%) of such Participant's W-2 Compensation (but
     without taking into account Social Security and similar contributions and
     benefits).  For purposes of this subparagraph C., all defined contribution
                                                   --                          
     plans of the Company shall be aggregated to the end that the percentage
     rules shall be satisfied if the aggregate contribution made to all defined
     contribution plans equals five percent (5%) of any nonkey Participant's W-2
     Compensation.

          C.   Effect on Section 415 Limitations.  If the Company maintains both
          --   ---------------------------------                                
     a 

                                      -43-
<PAGE>
 
     defined contribution plan and a defined benefit plan with a Participant who
     participates, or could participate, in both plans, then for purposes of
     computing the defined contribution fraction and defined benefit fraction
     described in subparagraph 8. J. hereunder, the dollar limitation of
                               -- -
     Sections 415(b)(1)(A) and 415(c)(1)(A) shall be multiplied by 1.0 in lieu
     of 1.25, unless:

               (1)  the defined contribution plan allocates to the account of
          each Participant who is not a key employee not less than seven and
          one-half percent (7-1/2%) of each such Participant's W-2 Compensation
          (without taking into account Social Security and similar contributions
          and benefits); and

               (2)  the plan would not be top-heavy if 90 percent were
          substituted for 60 percent in subparagraph A. above.
                                                     --       

     26.  Expenses of Administration.
     ---  -------------------------- 

     The Trustee's compensation shall be fixed by agreement from time to time
with the Company; provided, however, that no person compensated as an Employee
of the Company shall be compensated as a Trustee hereunder.  The Company intends
to pay, in addition to the contributions hereinbefore provided for, any expenses
of administering the Trust, including the Trustee's compensation, if any, except
that any investment counsel fees incurred by the Trust, and any expenses
directly related to particular transactions involving purchases or sales of
property by the Trust or the production or collection of income, such as
transfer taxes, brokers' commissions, etc., shall be paid by the Trustee out of
the assets of the Trust.

     27.  Rights of Participants.
     ---  ---------------------- 

     Participating in this Plan and Trust shall not give any Participant any
right to be retained in the service of the Company or any right or claim to any
benefits hereunder unless such benefits have accrued under the terms and
provisions of this Plan.

     28.  Claims Procedure.
     ---  ---------------- 

     Claims for benefits under the Plan may be filed with the Plan Administrator
on forms supplied by it.  Written notice of the disposition of a claim shall be
furnished to the claimant within 90 days after the application is filed.  In the
event the claim is denied, the reasons for the denial shall be specifically set
forth in the notice in language calculated to be understood by the claimant,
pertinent provisions of the Plan shall be cited, and, where appropriate, an
explanation as to how the claimant can perfect the claim will be provided.  In
addition, the claimant shall be 

                                      -44-
<PAGE>
 
furnished with an explanation of the Plan's claims review procedure, as
described below.

     Any Employee or Beneficiary who has been denied a benefit shall be entitled
to request the Plan Administrator to give further consideration to his claim by
filing with the Plan Administrator (on a form which may be obtained from the
Plan Administrator) a request for a hearing.  Such request, together with a
written statement of the reasons why the claimant believes his claim should be
allowed, shall be filed with the Plan Administrator no later than 60 days after
receipt of the written notification furnished by the Plan Administrator with
respect to the claim. The Plan Administrator shall then conduct a hearing within
the next 60 days, at which the claimant may be represented by an attorney or any
other representative of his choosing and at which the claimant shall have an
opportunity to submit written and oral evidence and arguments in support of his
claim. At the hearing (or prior thereto upon 5 business days written notice to
the Plan Administrator) the claimant or his representative shall have an
opportunity to review all documents in the possession of the Plan Administrator
which are pertinent to the claim at issue and its disallowance. Either the
claimant or the Plan Administrator may cause a court reporter to attend the
hearing and record the proceedings. In such event, a complete written transcript
of the proceedings shall be furnished to both parties by the court reporter. The
full expense of any such court reporter and such transcripts shall be borne by
the party causing the court reporter to attend the hearing. A final decision as
to the allowance of the claim shall be made by the Plan Administrator within 60
days of receipt of the appeal (unless there has been an extension of 60 days due
to special circumstances, provided the delay and the special circumstances
occasioning it are communicated to the claimant within the 60 day period). Such
communication shall be written in a manner calculated to be understood by the
claimant and shall include specific reasons for the decision and specific
references to the pertinent Plan provisions on which the decision is based.

     29.  Construction.
     ---  ------------ 

     It is intended that this Plan shall be construed so as to qualify as a tax-
free employees' profit-sharing plan and trust, contributions to which by the
Company shall be deductible from its net income.

     30.  Defense of Trust.
     ---  ---------------- 

     The Company shall have the right to defend the position of the Trust
created under this Plan as a tax-free profit-sharing trust.

     31.  Ohio Trust.
     ---  ---------- 

                                      -45-
<PAGE>
 
     This Plan is executed and delivered in the State of Ohio and the Trust
hereby created shall be deemed an Ohio trust and shall in all respects be
construed and regulated by the laws of the State of Ohio.

     32.  Mistaken Contributions, Etc.
     ---  ----------------------------

     Except as otherwise provided herein, the assets of the Plan shall not inure
to the benefit of the Company, and shall be held for the exclusive purposes of
providing benefits to Participants and Beneficiaries and defraying reasonable
expenses of administering the Plan.  Notwithstanding the foregoing sentence:

          (a)  If a contribution is made by the Company under a mistake of fact,
     such contribution may be returned, at the discretion of the Company, within
     one (1) year after payment of such contribution.

          (b)  All contributions to the Plan are conditioned on initial
     qualification of the Plan under Section 401 of the Code.  If the Plan does
     not so qualify for any Plan Year for which a contribution is made, such
     contribution may be returned, at the discretion of the Company, within one
     (1) year after the date of denial of initial qualification of the Plan
     provided that the application for qualification is made by the time
     prescribed by law for filing the Employer's tax return for the taxable year
     in which the Plan is adopted, or such later date as the Secretary of the
     Treasury may prescribe.

          (c)  All contributions to the Plan are conditioned upon the
     deductibility thereof, for Federal income tax purposes, under Section 404
     of the Code.  If and to the extent that such deduction is disallowed, the
     Company's contribution (to the extent disallowed) may be returned, at the
     discretion of the Company, within one (1) year after the disallowance of
     the deduction.

     Earnings attributable to the contributions to be returned to the Company
will not be returned to the Company, but losses attributable to such
contributions will reduce the amount to be returned.  Notwithstanding the
foregoing, if the Plan fails to initially qualify under Section 401 of the Code,

                                FIRST AMENDMENT
                      TO THE ADVANSTAR COMMUNICATIONS INC.
                        EMPLOYEES' 401(k) PLAN AND TRUST
                        --------------------------------


                               (1993 RESTATEMENT)


     THIS FIRST AMENDMENT is made this 31st day of March, 1994, by ADVANSTAR
COMMUNICATIONS INC. (the "company") to the Advanstar Communications Inc.
Employees' 401(k) Plan and Trust (the "Plan"), which was restated in its
entirety in 1993.

     WHEREAS, the Omnibus Budget Reconciliation Act of 1993 requires that all
qualified plans limit the amount of participant compensation that may be taken
into account in determining allocations under said plans and it is desired to
incorporate such limitations into the Plan; and

     WHEREAS, the Company acquired Aster Publishing Corporation and the Company
wishes to clarify that participants in the Aster Publishing Corporation Profit-
Sharing Plan are permitted to participate in the Plan; and

     WHEREAS, the Company wishes to liberalize certain provisions relating to
the 401(k) provisions of the Plan, all as permitted by final Treasury
Regulations;

     NOW THEREFORE, Pursuant to the provisions of Paragraph 21. of the Plan,
                                                            --
said Plan is hereby amended, as follows:

     FIRST:  Effective January 1, 1994, subparagraph 2.(e) is hereby deleted in
                                                     -
its entirety, and the following new subparagraph 2.(e) is substituted in lieu
                                                 -
thereof:

     "(e) `Compensation' shall mean the total compensation paid by the Company
      ---                                                                     
     to an Employee for services rendered for the period under consideration
     (other than compensation in the form of qualified or previously qualified
     compensation) that is currently includible in gross income of the Employee
     for income tax purposes.  `Compensation' shall also include amounts that
     are not includible in income of the Employee under Code Section 125 (except
     for amounts not includible in income under Code Section 125 which are
     applied to the payment of medical insurance premiums on behalf of such
     Employee)."

     SECOND: Effective January 1, 1994, subparagraph 2.(j) is hereby deleted in
                                                     --                        
its entirety, and the following new subparagraph 2.(j) is substituted in lieu
                                                 --                          
thereof:

     "(j) `Gross Compensation' shall mean the total compensation paid by the
      ---
     Company to an Employee for services rendered for the period under
     consideration (other than compensation in the form of qualified or
     previously qualified compensation) that is currently includible in gross
     income of the Employee for income tax purposes, plus all amounts not
     includible in income of the Employee under Code Section 125 and all amounts
     deferred hereunder pursuant to a salary reduction agreement.
<PAGE>
 
          For plan years commencing January 1, 1994 or later, the annual Gross
     Compensation of each Participant taken into account under the Plan for any
     plan year shall not exceed $150,000, as adjusted by the Commissioner of
     Internal Revenue for increases in the cost-of-living in accordance with
     Section 401(a)(17)(B) of the Code.  The cost-of-living adjustment in effect
     for a calendar year applies to any period, not exceeding 12 months, over
     which Gross Compensation is determined (determination period) beginning in
     such calendar year.  If a determination period consists of fewer than 12
     months, the annual compensation limit will be multiplied by a fraction, the
     numerator of which is the number of months in the determination period, and
     the denominator of which is 12.

          In determining the Gross Compensation of a Participant for purposes of
     this limitation, the rules of Section 414(q) of the Code shall apply,
     except in applying such rules, the term "family" shall include only the
     spouse of the Participant and any lineal descendants of the Participant who
     have not attained age 19 before the close of the year. If, as a result of
     the application of such rules, the adjusted $150,000 limitation is
     exceeded, then the limitation shall be prorated among the affected
     individuals in proportion to each such individual's Gross Compensation, as
     determined under this subparagraph prior to the application of this
     limitation."

     THIRD:  Effective January 1, 1993, Paragraph 4. is hereby deleted in its
                                                  --                         
entirety, and the following new Paragraph 4. is substituted in lieu thereof:
                                          --                                

          "4.  Plan Entry Requirements.
           --  ----------------------- 

          Each Employee of the Company shall enter the Plan on the first day of
     the calendar month next following the later to occur of the end of the 12-
     month period of service which constitutes a Year of Service with respect to
     such Employee and his attainment of age twenty-one (21). Notwithstanding
     the foregoing, if an Employee is a non-resident alien who receives no
     earned income (within the meaning of Section 911(d)(2) of the Code) from
     the Company which constitutes income from sources within the United States
     (within the meaning of Section 861(a)(3) of the Code), such Employee shall
     be ineligible to enter into a salary reduction agreement pursuant to
     subparagraph 5.A. hereof.
                  ----        

          Individuals who are United States citizens and who are employed by a
     foreign subsidiary corporation or a domestic subsidiary whose operations
     are largely foreign shall be considered as Employees of the Company and
     shall be permitted to participate in this Plan (including the right to
     enter into a salary reduction agreement) provided that the Company extends
     social security coverage to such individuals and further provided that such
     U.S. citizen employees are not provided contributions under a funded plan
     of deferred compensation by any other person with respect to compensation
     paid to such U.S. citizen employees by the foreign subsidiary or domestic
     subsidiary with largely foreign operations.

          With respect to an Employee who has met the eligibility requirements
     of the Plan
        
                                      -2-
<PAGE>
 
     but who has incurred a One-Year Break in Service, such Employee shall be
     eligible to re-enter the Plan commencing immediately upon his return.  In
     the event an Employee who is not a member of an eligible class of employees
     becomes a member of an eligible class, such employee will participate
     immediately if such Employee has satisfied the minimum age and service
     requirements and would have otherwise previously become a Participant.  In
     the event that the eligibility of any person to participate in the Plan
     shall be disputed, the decision of the Trustee upon such eligibility shall
     be controlling.  For the purposes of enabling the Trustee to make such
     determination, all information available to the Company which shall be
     required by the Trustee shall be made available to the Trustee."

     FOURTH:   Effective January 1, 1994, subparagraph 6.B. (3) is hereby
                                                       ---
deleted in its entirety, and the following new subparagraph 6.B.(3) is
substituted in lieu thereof:

          "(3) Payment of tuition and related educational fees for the next 12
     months of post-secondary education for the Participant, his spouse,
     children, or dependents; or"

     FIFTH:    Effective January 1, 1989, subparagraph 7.A.(1) at page 17, is
                                                       -------
hereby deleted in its entirety, and the following new subparagraph 7.A.(1) is
                                                                   -------
substituted in lieu thereof:

          "(1) The combined actual deferral ratio for the family group (which
     shall be treated as one Highly Compensated Employee) shall be determined by
     aggregating Salary Reduction Contributions and Gross Compensation of all
     eligible Family Members (including Highly Compensated Employees)."

     SIXTH:    Effective January 1, 1994, subparagraph 8.H.(1) is hereby deleted
                                                       -------
in its entirety, and the following new subparagraph 8.H.(1) is substituted in
                                                    -------
lieu thereof:

          "(1) Any contributions made pursuant to a salary reduction agreement,
     to the extent they would reduce the excess amount, will be returned to the
     Participant;"

                                      -3-

                               SECOND AMENDMENT
                     TO THE ADVANSTAR COMMUNICATIONS INC.
                       EMPLOYEES' 401(K) PLAN AND TRUST
                       --------------------------------
                                        
                              (1993 RESTATEMENT)
                                        
     THIS SECOND AMENDMENT is made this 18th day of August, 1994, by and among
ADVANSTAR COMMUNICATIONS INC. (the "Company") and MARY ABOOD, TEUTA CENAJ, BYRON
GLIDDEN, DAVID MONTGOMERY, and PHILLIP STOCKER (collectively the "Trustee"), to
the Advanstar Communications Inc. Plan and Trust (the "Plan"), which was
restated in its entirety in 1993.

     Pursuant to the provisions of Paragraph 21. of the Plan, said Plan is
                                             --                           
hereby amended, effective the 1st day of September, 1994, by the deletion of
subparagraph 2 (w) in its entirety and the substitution of the following new
             -----                                                          
subparagraph 2 (w) in lieu thereof:
             -----                 

               "(w)  "Vesting Year of Service" shall mean a period of  twelve
          (12) consecutive months during which a Participating Employee either
          (i) completes at least One (1) Hour of Service and is employed on the
          last day of the twelve-month period, or (ii) completes at least One
          Thousand (1,000) Hours of Service without regard to employment on the
          last day of the twelve-month period.  Such twelve-month period shall
          be calculated with reference to the Employee's "Employment
          Commencement Date" (the first date of employment on which the Employee
          is credited with an Hour of Service with the Company), and subsequent
          twelve-month periods shall be calculated with reference to subsequent
          anniversaries of said Employment Commencement Date.

               The number of Hours of Service to be credited to an Employee for
          determining whether a Vesting Year of Service has been completed shall
          be computed on equivalencies based on periods of employment in
          accordance with Department of Labor Regulation (S)2530.200b-3(e) as
          follows:

               If an Employee is paid on a weekly basis, the Employee shall be
          credited with 45 Hours of Service for each week for which the Employee
          would otherwise be credited with at least one Hour of Service pursuant
          to subparagraph 2 (1).
                          ----- 

               If an Employee is paid on a bi-weekly basis, the Employee shall
          be credited with 90 Hours of Service for each such two-week period for
          which the Employee would otherwise be credited with at least one Hour
          of Service pursuant to subparagraph 2 (1).
                                              ------

               In determining Vesting Years of Service, service with Harcourt
          Brace Jovanovich, Inc. shall be considered as service with the
          Company.
<PAGE>
 
               An Employee who ceases to be a Participant, but who remains in
          the employment of the company, shall continue to be credited with
          Vesting Years of Service under this Plan so long as he remains in the
          employment of the Company.  An Employee who was in the employment of
          the Company before he became an Employee for purposes of this Plan
          shall receive credit for Vesting Years of Service as though he had
          been an Employee during such prior period of employment with the
          Company."

     In no event shall any Participating Employee's Vesting Years of Service be
reduced by virtue of this amendment.  If a Participating Employee satisfied the
requirements for a Vesting Year of Service prior to this amendment for a
particular twelve-month period, the Participating Employee shall continue to
receive credit for a Vesting Year of Service for such period, notwithstanding
this amendment.

     IN WITNESS WHEREOF, this Second Amendment has been executed by the Company,
pursuant to action of its Board of Directors, and by the Trustee as of the day
and year first above written.

                            THIRD AMENDMENT TO THE
                         ADVANSTAR COMMUNICATIONS INC.
                       EMPLOYEES' 401 (K) PLAN AND TRUST
                       ---------------------------------

                               (1993 RESTATEMENT)

     THIS AMENDMENT is made this 10th day of January, 1996, by ADVANSTAR
COMMUNICATIONS INC. (the "Company") to the Advanstar Communications Inc.
Employees' 401(k) Plan and Trust  (the "Plan"), which was restated in its
entirety in 1993.

     WHEREAS, the Company wishes to clarify certain language in the plan with
respect to the determination of matching contributions and the performance of
certain nondiscrimination tests;

     NOW, THEREFOR, pursuant to the provisions of Paragraph 21. of the Plan,
                                                            ---             
said Plan is hereby amended by the replacement of pages 11, 12 and 17 of the
Plan with the pages 11, 12 and 17 attached hereto.

     IN WITNESS WHEREOF, this Amendment has been executed by the Company,
pursuant to action of its Board of Directors, as of the day and year first above
written.

                              ADVANSTAR COMMUNICATIONS INC.

                                   /s/ David Montgomery
                              By:_________________________________
                                   David Montgomery,
                                   Chief Financial Officer
<PAGE>
 
               (5) The Company may refrain from making contributions to this
          Plan, in respect of the salary reduction agreement entered into by the
          Participant, if the Company determines that such action is necessary
          to insure that the Participant's annual additions for any Plan Year
          will not exceed the limitations of subparagraphs 8. H. or 8. I.
                                                           -- --    -- --
          hereinbelow, or to insure that the Actual Deferral Percentage Test
          described in Paragraph 7. hereinbelow is met for such Plan Year.  In
                                 --                                           
          any such event, the Company may pay to the Participant the amount
          which otherwise would have been paid prior to the Participant's
          election to reduce his salary, rather than as a contribution made
          pursuant to a salary reduction agreement.

               (6) A salary reduction agreement shall not provide for a
          reduction in excess of $7,000 (or such higher amount as determined by
          the Secretary pursuant to Section 415(d) of the Code) under all plans
          maintained by the Company with respect to any Employee's taxable year.

     B.  Matching Company Contributions.  Not later than the time prescribed by
     -   ------------------------------                                        
law for filing its federal income tax return including any extensions thereof)
for its current taxable year, the Company shall contribute to the Trustee, on
behalf of each Participant, as its Matching Company Contribution to the Trust
for the Plan Year which ends within or which is co-terminous with such taxable
year of the Company, to be held in trust, administered and distributed under the
terms of this Agreement, an amount to be determined as follows:

               (1) With respect to Salary Reduction Contributions up to the
          first two percent (2%) of the Participant's Compensation, the Matching
          Company Contribution shall be equal to 100% of the Salary Reduction
          Contribution;

               (2) With respect to Salary Reduction Contributions in excess of
          two percent (2%) of the Participant's Compensation and not in excess
          of six percent (6%) of the Participant's Compensation, the Matching
          Company Contribution shall be equal to 25% of such Salary Reduction
          Contribution; and

               (3) With respect to Salary Reduction Contributions in excess of
          six percent (6%) of the Participant's Compensation, there shall be no
          Matching Company Contribution.  In no event shall the Matching Company
          Contribution made on behalf of a Participant in a Plan Year exceed
          three percent (3%) of the Participant's Compensation.

     In determining the Matching Company Contribution, the computation of the
Salary Reduction Contribution as a percentage of Compensation shall be made on a
per payroll basis.

     Notwithstanding the foregoing, the Company shall not contribute to the Plan
as a Matching Company Contribution any amount that would cause the limitation
set forth in Paragraph 7. to be exceeded, considering only Matching Company
                       --                                                  
Contributions, rather than Salary Reduction Contributions
<PAGE>
 
     C.  Discretionary Company Contributions.  Not later than the time
     -   -----------------------------------                          
prescribed by law for filing its federal income tax return (including extensions
thereof) for its current taxable year and for each succeeding taxable year, the
Company may contribute to the Trust fund, as its contribution to this Trust for
the Plan Year which ends within or which is co-terminous with such taxable year
of the Company, to be held in trust, administered and distributed under the
terms of this Agreement, an amount or amounts which the Company, in its sole
discretion may determine.  The Company may contribute such amount or amounts at
any time; and it may make such contribution in two or more installments.

     The Company shall determine by resolution of its Board of Directors and
communicate to the Trustee before the close of each Plan Year either (i) the
amount in dollars to be contributed for such year, or (ii) a formula by which
such amount may be determined.  These contributions shall be totally in the
discretion of the Company with respect to amount, timing and form, and they need
not be limited to the Employee group for a Plan Year, the average of the ratios,
calculated separately for each Participant in such group, of the amount of
Salary Reduction Contributions allocated to each participant's Salary Reduction
Contribution Account for such Plan Year to such Participant's Gross Compensation
for such Plan Year.  The actual deferral ratio for each Participant and the
"Actual Deferral Percentage" for each group shall be calculated to the nearest
one-hundredth of one percent.

     For the purpose of determining the actual deferral ratio of a Highly
Compensated Employee who is subject to the Family Member aggregation rules of
Code Section 414(q)(6) because such Participant is either a "five percent owner"
of the Employer or one of the ten (10) Highly Compensated Employees paid the
greatest "415 Compensation" during this year, the following shall apply:

               (1) The combined actual deferral ratio for the family group
          (which shall be treated as one Highly Compensated Employee) shall be
          determined by aggregating Salary Reduction Contributions and Gross
          Compensation of all eligible Family Members (including Highly
          Compensated Employees).

               (2) The Salary Reduction Contributions and Gross Compensation of
          all Family Members shall be disregarded for purposes of determining
          the "Actual Deferral Percentage" of the Non-Highly Compensated
          Employee group except to the extent taken into account in paragraph
          (1) above.

               (3) If a participant is required to be aggregated as a member of
          more than one family group in a plan, all Participants who are members
          of those family groups that include the Participant are aggregated as
          one family group in accordance with paragraphs (1) and (2) above.

                                 July 31,1997



THIS AMENDMENT ONE is made to those certain agreements by and between ADVANSTAR
COMMUNICATIONS, INC. ("Customer") and BANTA PUBLICATIONS GROUP (two divisions of
Banta Corporation, f/k/a The Hart Press and Clark Printing Company; collectively
and individually herein, "Printer") dated May 5, 1995, and identified as
Agreement C-104 1-R2 and Agreement H-1066-R2 (the "Agreements"), effective July
28, 1997.

WHEREAS, Customer and Printer desire to amend the Agreements, which shall remain
in full force and effect with the modifications and additions set forth below;

THEREFORE, in consideration of the mutual covenants contained herein, Customer
and Printer agree as follows:

(1) The terms of the Agreements are extended from December 31, 2000 to December
31, 2002.

(2) Effective with Printer's invoices dated July 28, 1997, Printer will reduce
Customer's current manufacturing prices by four percent (4%) and furnish
Customer a revised price schedule reflecting this change within fifteen (15)
days of Customer's acceptance. Such revised prices shall remain firm through
December 31, 1998.

(3) The annual escalation cap, as included in Section 3-A of the Agreements,
shall be reduced to one percent (1%) in 1999 and remain at two percent (2%) in
years 2000, 2001 and 2002.

(4) The Printer will rebate a certain percentage of the aggregate annual
billings, invoiced to Customer from Printer, excluding paper, ink and freight,
upon achieving the following annual sales levels:

<TABLE>
<CAPTION>
Sales Range excluding paper ink and freight:    Progressive Rebate Percent
- --------------------------------------------    --------------------------
<S>                                             <C>
- -$7.50 - $7.99 Million                          One Half (1/2%) percent
- -$8.00 - $8.50 Million                          One (1%) percent
- -$8.51 - $8.99 Million                          One and one half (1-1/2) percent
- -$9.00 - $9.50 Million                          Two (2%) percent
- -$9.51 - $9.99 Million                          Two and one half (2-1/2) percent
- -$10.00 - $10.50 Million                        Three (3%) percent
- -$10.51 - $10.99 Million                        Three and one half (3-1/2%) percent
- -$11.00 - $11.50 Million                        Four (4%) percent
- -$11.51 - $11.99 Million                        Four and one half (4-1/2%) percent
- -$12.00 Million and more                        Five (5%) percent
</TABLE>
<PAGE>
 
If the Customer's 1997 year-end aggregate annual billings, excluding paper, ink
and freight are below $7 Million, this chart will be re-calculated with the same
increments at value $500,000 higher than the Customer's 1997 year-end aggregate
annual billings, excluding paper, ink and freight.

The rebate will be calculated on a calendar year basis, beginning January 1,
1998, and include all work that is invoiced to Customer, by Printer, within the
calendar year.  The rebate, if any, will be made within sixty (60) days of the
calendar year end and be applied as a credit to the Customer's account balance.

(5) Customer will begin to phase in its remaining mail prep requirements,
beginning in January, 1998, upon Printer's demonstrated ability and capability
to efficiently prepare and process Customer's mail lists. Mail prep requirements
will include list sortation, label output and other related postal requirements,
that Customer may request, from time to time.

(6) Printer has expressed an interest in furnishing Customer's paper
requirements and will submit a separate proposal to Customer. Upon receipt of
Printer's proposal, Customer will have the right to accept, in whole or part,
Printer's paper proposal. Customer shall not be obligated to accept Printer's
paper proposal, in whole or part, but has assured Printer that it will, in good
faith, evaluate Printer's proposal. If in the event Customer rejects Printer's
paper proposal, Customer will assist Printer to improve and/or enhance
runnability of paper furnished by Customer should such paper adversely affect
Printer's pressroom performance.

     1.  Subject of Agreement.  Advanstar Communications, Inc. ("Customer"), a
         ---------------------                                                
New York corporation located at 131 West First Street, Duluth, Minnesota 55802

December 31, 2000.

     2.  Prices.  Prices for Printer's services are set forth in the attached
         ------                                                              
Price Schedule.  Those prices are based upon (i) Printer's labor costs on the
date of this Agreement, (ii) Printer's material costs on the date of this
Agreement and (iii) Customer's specifications set forth in the Specifications
Schedule.  Any volume or trade discounts earned with respect to materials or
services utilized by Printer or for which Printer contracts on behalf of
Customer in connection with Printer's performance under this Agreement shall be
and remain the property of the Printer.

     Customer recognizes that Printer's prices are exclusive of: (a)
transportation charges, (b) charges for storage of paper and other materials
furnished by Customer and of finished goods produced by Printer and (c) any
manufacturer's, retailer's occupation, use, sales, excise, value added or other
tax, or any charge of any nature whatsoever imposed by any governmental
authority.  Any such tax or charge shall be the responsibility of the Customer;
charges for storage and transportation by Printer shall be based on Printer's
standard rates in effect from time to time.

     3.  Price Adjustments.
         ----------------- 

A.   Except as provided in Section 2 above and in subsections 3B and 3C below,
prices in this Agreement shall remain firm through December 31, 1996.
Thereafter, prices shall be adjusted to proportionately reflect a increases or
decreases, since the effective date of this Agreement, in labor costs, including
state or federal social security taxes or other taxes related to labor
utilization. However, in no such case shall the annual increase exceed two (2%)
percent.
<PAGE>
 
                                      -2-
 
B.   Printer will, on or before the effective date of any price change under
this Agreement, provide to Customer notice and an explanation of such change,
together with appropriate supporting data.

     4.   Payment Terms.
          ------------- 

A.   Net payment shall be made in advance of the production date as outlined in
Exhibit B attached. Printer reserves the right to amend and/or adjust weekly
payment amounts as necessary.

B.   Printer shall invoice Customer as follows:

     (1)  Preparatory work, plates, presswork, binding, cartons, pallets,
     services preparatory for mailing finished work, freight and shipping
     charges, and paper furnished by Printer - upon completion of Printer's
     services with respect to each shipment of work under this Agreement;
     provided, however, that if the Customer delays the performance of Printer's
     services as established in the Production Schedule, printer may invoice for
     services rendered to date.

     (2)  Storage of paper and other materials furnished by Customer and of
     finished work produced by Printer - as provided for in Sections 14 and 15.

     5.   Production Schedule.  Each of the parties will use its best efforts to
          -------------------                                                   
comply with the Production Schedule at all times.  Customer's delay in
furnishing and/or returning all paper, copy, specifications, artwork, proofs,
copies or other material in accordance with the Production Schedule may result
in an extension of scheduled delivery date(s) and/or additional charges to
Customer for accelerated production at Printer's standard overtime rates then in
effect.  Any additional charges incurred by Printer on behalf of Customer, must
be pre-approved by Customer in advance of the charges incurred.

     6.   Proofs.  Printer shall furnish Customer the proofs and materials set
          ------                                                              
forth in the Specifications Schedule; and Customer shall return to Printer one
set of proofs for each completed page indicating any and all changes (editorial
and art). Printer shall not be liable for errors or subsequent corrective costs
for work completed pursuant to Customer's approval or for errors due to
Customer's failure to order proofs, refusal to accept proofs, failure to return
proofs marked with changes, or Customer's instructions to proceed without
submission of proofs.

     7.   Materials Furnished by Customer.  Paper stock, film (negatives and
          -------------------------------                                   
positives), and other materials furnished by Customer shall be properly packed,
free from dirt, grit, torn sheets, bad splices, etc. and shall comply with the
specifications set forth in the Specifications Schedule, and within S W O P
standards.  Additional costs due to delays, impaired production or the necessity
to repair or replace such materials because of Customer's failure to meet such
standards shall be charged to Customer at Printer's standard rates then in
effect.  Semi-finished materials or covers furnished by Customer shall include
manufacturing waste allowances Printer deems adequate and shall be adjusted to
Printer's count.
<PAGE>
 
                                      -3-
 
     Printer shall not be liable for the fitness of any materials furnished by
Customer unless directed by Customer, at additional cost to Customer, to make
corrections, repairs, or substitutions Printer deems necessary.  In no event
does Printer assume responsibility for color fidelity of finished goods made
from film furnished by Customer, unless proofed by Customer to Printer's
requirements.

     8.   Responsibility for Content; Right to Rescind.  Customer warrants that
          --------------------------------------------                         
any matter it furnishes for printing pursuant to this Agreement does not
infringe any copyright or trademark, is not libelous, and does not otherwise
violate any law or infringe the rights of any third party.  Customer agrees to
indemnify and hold Printer harmless against all losses, claims, damages,
liabilities and expenses, including Printer's attorneys' fees, which Printer may
incur as the result of any claims of such violation or infringement.  Printer
shall have the right, without liability of any kind to Customer, to refuse to
print any publication containing material that, in Printer's good faith
judgment, may give rise to such claims.

     9.   Business Reply Mail.  Customer shall be responsible for complying with
          -------------------                                                   
all postal service requirements concerning business reply mail; and Printer
shall not be liable to Customer for any damages or claims whatsoever in the
event that business reply mail is rejected by the postal service.

     10.  Quantity Variation.  Variations in quantity of 0% over and 0% under
          ------------------                                                 
quantities ordered shall constitute acceptable delivery; and the excess or
deficiency shall be charged or credited at the "additional thousands" rate set
forth in the Price Schedule.

     11.  Warranty.  Printer warrants that its services shall be performed
          --------                                                        
according to the terms of this Agreement and S W O P standards acceptable in the
printing industry.  However, due to differences in equipment, paper, inks, and
other conditions between the color proofing and production pressroom operations,
a reasonable variation in color between color proofs and the completed job, and
a reasonable variation on press, may exist.  Work containing such variations
shall be considered in conformity with this warranty.  Customer however,
retains, sole and absolute discretion in determining whether standards of
quality are sufficient.  In the event Customer reasonably concludes performance
of Printer is inadequate, then Customer may, with 30 days written notice, remove
affected publications(s) from Printer without penalty to Customer.

     12.  Risk of Loss.  The risk of loss of finished work shall pass to the
          ------------                                                      
Customer F.O.B. the facilities at which the same was printed, upon the earlier
of Printer's delivery to carrier or postal service, or delivery into storage,
regardless of whether the transport medium or storage facilities are owned
and/or operated by Printer.  The risk of loss of property furnished and/or owned
by Customer shall be on the Printer while such property is at the facilities at
which the printing is to occur.  Customer shall bear the risk of loss while
property is in transit to and from Printer's facilities.

                                      -4-
 
     13.  Passage of Title.  Title to finished goods shall pass to Customer upon
          ----------------                                                      
the earlier of Printer's delivery to carrier or postal service, or delivery into
storage, regardless of whether the transport medium or storage facilities are
owned and/or operated by Printer.  Artwork, drawings, sketches, dummies, film
positives, negatives, and separations furnished by Printer shall become the
property of Customer upon completion of printing and payment therefor; provided,
however, that if such items are furnished by Printer by subcontracting the
production thereof, then title thereto shall pass to Customer upon shipment to
Printer.  All printing plates shall be and remain the property of Printer.

     14.  Storage.  Customer's materials which are in film form shall be stored
          -------                                                              
without charge for a period of 12 months from the time of last use and
thereafter destroyed.  If Customer's materials other than film are not shipped
within 24 hours after notification to Customer that they are ready to be
shipped, for any reason beyond Printer's reasonable control, including but not
limited to Printer's retention of such materials pursuant to Section 18 below,
Printer may store such materials at Customer's risk in a warehouse or at the
facilities at which printing occurred, and Customer shall pay all resulting
handling, transportation and storage charges as invoiced by Printer.

     15.  Customer Furnished Paper.  If Customer furnishes paper, Printer agrees
          ------------------------                                              
to provide storage, at no cost to Customer, for up to two (2) months supply.
Inventory levels exceeding two (2) months supply are subject to storage charges
which are included in the Price Schedule.

     16.  Contingencies.  Printer shall not be liable for any delay or failure
          -------------                                                       
to perform under this Agreement if such delay or failure to perform arises out
of causes beyond its reasonable control, including but not limited to labor
trouble, fires, severe weather and other acts of God, accidents, governmental
acts and regulations, inability to obtain materials or carrier space or
equipment, or delays of suppliers or carriers.  Printer shall give notice to
Customer of any such condition within a reasonable time after it arises.

     If Printer's operations are suspended for any of the above causes, Printer
shall have the right to have the work performed by one of its subsidiaries on
the same terms and conditions set forth in this Agreement.

     If Printer is unable for any reason to have the work done by one of its
subsidiaries, Customer shall have the right to have the services covered by this
Agreement performed elsewhere, and to remove from Printer's plant any and all
completed work, proofs, film, paper and other material and uncompleted work only
upon payment to Printer for all services rendered and materials furnished or
ordered by Printer prior to the date of suspension of operations.

     The parties agree that when Printer resumes operation, upon 30 days'
written notice to Customer, production shall resume and continue at Printer's
facilities under the terms and conditions of this Agreement.

     17.  Claims.  All claims for defective or damaged product or for shortages
          ------                                                               
must be made by Customer in writing fully setting forth the nature of the
alleged defect, damage or

<PAGE>
 
                                      -5-
 
shortage, within 30 days after Customer's receipt thereof. Customer's failure to
so notify Printer shall constitute irrevocable acceptance of the product and a
waiver of any claim of defect, damage or shortage. Claims for damage or loss in
transit must be made by Customer directly against the carrier.

     18.  Limitation of Remedies.  Customer's sole and exclusive remedy for
          ----------------------                                           
Printer's negligence or other tort, breach of warrant or contract or any other
claim arising out of or connected with to that portion of the work which is
nonconforming or, at Printer's option, printing of a correction in subsequent
work, if applicable.

              IN NO EVENT SHALL PRINTER BE LIABLE FOR ANY SPECIAL,
              INDIRECT OR CONSEQUENTIAL DAMAGES, WHETHER FOR BREACH OF
              CONTRACT OR WARRANTY, NEGLIGENCE OR OTHER TORT OR ON ANY
              STRICT LIABILITY THEORY.

     19.  Printer's Security Interest and Rights Upon Customer's Default.  If
          --------------------------------------------------------------     
any amount due Printer from Customer shall remain unpaid at the due date, or if
Customer defaults in the performance of any other covenant or condition of this
Agreement or any other agreement with Printer, Printer shall have the right to
terminate its obligations under this Agreement, to declare immediately due and
payable all obligations of the Customer for the work theretofore furnished by
the Printer under this Agreement, to retain possession of any product or
materials owned by Customer (including but not limited to work-in-process and
undelivered work) pending payment in full of all such obligations, to change
credit terms with respect to any further work furnished by Printer, and/or to
suspend or discontinue any further performance for Customer until overdue
amounts are paid in full and until cash or security satisfactory to Printer
covering further work, as may be require by Printer, is deposited in advance
with Printer.  These rights of Printer shall be in addition to and not in
substitution for any other rights of Printer; and suspension or discontinuance
of work by Printer pursuant to this Section shall not in any way prejudice any
claim or right of action which Printer may have by reason of any breach of this
Agreement or any other agreement by Customer.

     20.  Right to Assurance.  Whenever either party in good faith has reason to
          ------------------                                                    
question the ability or intent of the other party to perform, the party having
such question may demand in writing adequate assurance from the other party of
its ability or intent to perform, and may suspend performance under this
Agreement pending such assurance.  In the event that such a demand is made and
such assurance is not given within a reasonable time, the party having made such
demand may treat that failure as an anticipatory repudiation of this Agreement
and exercise any appropriate remedy for repudiation.

     21.  Bankruptcy.  If either party makes an assignment for the benefit of
          ----------                                                         
creditors, or admits in writing its failure or inability to pay its debts as
they become due, or becomes the subject of an "order for relief" within the
meaning of that phrase in the U.S. Bankruptcy Code, or applies for or consents
to the appointment of a receiver for any of its property, the other party
<PAGE>
 
                                      -6-
 
may terminate this Agreement at any time, effective immediately upon notice.
Such termination shall not relieve either party from any obligations accrued
under this Agreement up to the date of notice of termination.

     22.  Waivers.  No waiver by either party of any default by the other in the
          -------                                                               
performance of or compliance with any provision, condition or requirement in
this Agreement shall be deemed to be a waiver of, or in any manner release such
other party from compliance with any such provision, condition or requirement in
the future; nor shall any delay or omission of either party to exercise any
right under this Agreement or otherwise in law in any manner impair the exercise
of any such right thereafter.

     23.  Other Work.  In the event that, at any time during the term of this
          ----------                                                         
Agreement, Customer requests that Printer perform any work not related to the
publication(s) identified in Section 1 above, and Printer agrees to do so, all
rights and liabilities of Customer and Printer arising in connection with such
other work (as well as the rights and liabilities of the parties in connection
with Printer's work on the publication(s) identified in Section 1 above) shall
be governed exclusively by the terms and conditions contained in this Agreement;
provided, however, that, with respect to such other work, the Specifications,
Price and Production Schedules to this Agreement shall be superseded by
specifications, scheduling terms, quantities and prices set forth in accepted
orders, to the extent that the same are inconsistent with such Schedules.  No
additional or different terms contained in any of Customer's forms or other
correspondence shall be of any force or effect.

     24.  Entire Agreement.  The attached Specifications Schedule and Price
          ----------------                                                 
Schedule and the Production Schedule either attached or established in
accordance with this Agreement form a part of this Agreement.  This Agreement,
together with such Schedules, is intended by the parties as the final and
exclusive expression of their agreement, superseding all prior oral or written
agreements, understandings, negotiations, representations and correspondence
between the parties, on the subject of this Agreement.  There are no conditions
to this Agreement not expressed in this Agreement.

     25.  Term and Termination.  This Agreement shall take effect September 5,

1995 and shall remain in effect through December 31, 2000.  Either party may
terminate this Agreement at any time upon written notice to the other, but only
by specific reference to this Agreement (by title and date) in such notice.  Any
such termination shall have no effect upon the respective rights and liabilities
of the parties in connection with any work previously performed under this
Agreement or in process on the date of termination, or in connection with any
accepted order under this Agreement, including but not limited to the commitment
set forth in Section 1 above.

     26.  Amendment.  Except as provided in Sections 2 and 3, this Agreement,
          ---------                                                          
including the Schedules made a part of this Agreement, may be amended or
supplemented only by a writing signed on behalf of both of the parties by their
duly authorized representatives.  In the event that the Production Schedule is
not attached, mutual agreement to a Production Schedule shall be established
only by a writing so signed.

December 20, 1994


Ms. Adele Hartwick, Treasurer and Controller
Advanstar Communications
131 W. 1st St.
Duluth MN 55802


Dear Adele:

I have taken the opportunity to summarize our conversation from last Friday and
to outline how Advanstar's account will be administered beginning in 1995.  If
you have any question with any of the points below, please call me as soon as
possible.

1.   Effective January 1, 1995, Advanstar's credit terms will be changed from
     2%-10 days, Net 30 to "Cash in Advance."

2..  In consideration of cash in advance terms, Banta will abate the contractual
     2% manufacturing price increase.

3.   Since payments are to be made in advance, the 2% early pay discount will be
     reflected in Advanstar's new (1995) price schedules.

4.   Payment amounts will be broken down into equal weekly payments which are to
     be received every Friday beginning on December 30, 1994.

5.   Initial weekly payments, which include both production and postage, have
     been set at $125,000 to The Hart Press and $60,000 to Clark Printing
     Company.

     6.  Advanstar's account will be reviewed monthly.  Changes, if any, to the
     weekly payments will be assessed through anticipated production and
     reconciliation of payments to actual invoices.  Within Banta, this will
     have to be a coordinated effort with Jim Robison-Sales Representative,
     Customer Service, and the Controllers at both plants (Dave Wampole - The
     Hart Press and Phil Zuptich - Clark Printing Co.).

You and I will need to remain in contact as these payment amounts are
determined.  I will ask both Dave and Phil to provide appropriate support for
their recommended payment amounts.

                                 PROPOSAL FOR

                        ADVANSTAR COMMUNICATIONS, INC.

                               SEPTEMBER 5, 1995


     1.  Subject of Agreement.  Advanstar Communications, Inc. ("Customer"), a
         --------------------                                                 
New York corporation located at 131 West First Street, Duluth, Minnesota 55802
and Clark Printing Company ("Printer), a division of Banta Corporation, located
at 3401 Heartland Drive, Liberty, Missouri 64068 agree that Printer shall print
all of Customer's requirements for the publication(s) identified as (Refer to
Exhibit A attached), commencing September 5, 1995 and continuing through
December 31, 2000.  Printer shall perform those printing services in accordance
with the specifications and within the time(s) set forth, respectively, in the
attached Specifications Schedule, and the Production Schedule either attached or
(if not attached) established by mutual agreement of the parties conforming to
Section 25 below.  This Agreement shall also apply to other, future work
performed by Printer for Customer, as provided in Section 22 below.  Upon
expiration of the initial term, this Agreement shall be renewed for one (1)
year, unless either party gives written notice to the other of its intent to
terminate this Agreement not less than ninety (90) days prior to the expiration
date of December 31, 2000.

     2.  Prices.  Prices for Printer's services are set forth in the attached
         ------                                                              
Price Schedule.  Those prices are based upon (i) Printer's labor costs on the
date of this Agreement, (ii) Printer's material costs on the date of this
Agreement and (iii) Customer's specifications set forth in the Specifications
Schedule.  Any volume or trade discounts earned with respect to materials or
services utilized by Printer or for which Printer contracts on behalf of
Customer in connection with Printer's performance under this Agreement shall be
and remain the property of the Printer.

     Customer recognizes that Printer's prices are exclusive of: (a)
transportation charges, (b) charges for storage of paper and other materials
furnished by Customer and of finished goods produced by Printer and (c) any
manufacturer's, retailer's occupation, use, sales, excise, value added or other
tax, or any charge of any nature whatsoever imposed by any governmental
authority.  Any such tax or charge shall be the responsibility of the Customer;
charges for storage and transportation by Printer shall be based on Printer's
standard rates in effect from time to time.

     3.  Price Adjustments.
         ----------------- 

A.   Except as provided in Section 2 above and in subsections 3B and 3C below,
prices in this Agreement shall remain firm through December 31, 1996.
Thereafter, prices shall be adjusted to proportionately reflect any increases or
decreases, since the effective date of this Agreement, in labor costs, including
state or federal social security taxes or other taxes related to labor
utilization. However, in no such case shall the annual increase exceed two (2%)
percent.

<PAGE>
 
                                      -2-

B.  Printer will, on or before the effective date of any price change under this
Agreement, provide to Customer notice and an explanation of such change,
together with appropriate supporting data.

     4.  Payment Terms.
         ------------- 

A.  Net payment shall be made in advance of the production date as outlined in
Exhibit B attached.  Printer reserves the right to amend and/or adjust weekly
payment amounts as necessary.

B.  Printer shall invoice Customer as follows:

    (1) Preparatory work, plates, presswork, binding, cartons, pallets, services
    preparatory for mailing finished work, freight and shipping charges, and
    paper furnished by Printer - upon completion of Printer's services with
    respect to each shipment of work under this Agreement; provided, however,
    that if the Customer delays the performance of Printer's services as
    established in the Production Schedule, printer may invoice for services
    rendered to date.

    (2) Storage of paper and other materials furnished by Customer and of
    finished work produced by Printer - as provided for in Sections 14 and 15.

     5.  Production Schedule.  Each of the parties will use its best efforts to
         -------------------                                                   
comply with the Production Schedule at all times.  Customer's delay in
furnishing and/or returning all paper, copy, specifications, artwork, proofs,
copies or other material in accordance with the Production Schedule may result
in an extension of scheduled delivery date(s) and/or additional charges to
Customer for accelerated production at Printer's standard overtime rates then in
effect.  Any additional charges incurred by Printer on behalf of Customer, must
be pre-approved by Customer in advance of the charges incurred.

     6.  Proofs.  Printer shall furnish Customer the proofs and materials set
         ------                                                              
forth in the Specifications Schedule; and Customer shall return to Printer one
set of proofs for each completed page indicating any and all changes (editorial
and art). Printer shall not be liable for errors or subsequent corrective costs
for work completed pursuant to Customer's approval or for errors due to
Customer's failure to order proofs, refusal to accept proofs, failure to return
proofs marked with changes, or Customer's instructions to proceed without
submission of proofs.

     7.  Materials Furnished by Customer.  Paper stock, film (negatives and
         -------------------------------                                   
positives), and other materials furnished by Customer shall be properly packed,
free from dirt, grit, torn sheets, bad splices, etc. and shall comply with the
specifications set forth in the Specifications Schedule, and within S W O P
standards.  Additional costs due to delays, impaired production or the necessity
to repair or replace such materials because of Customer's failure to meet such
standards shall be charged to Customer at Printer's standard rates then in
effect.  Semi-finished materials or covers furnished by Customer shall include
manufacturing waste allowances Printer deems adequate and shall be adjusted to
Printer's count.
<PAGE>
 
                                      -3-

     Printer shall not be liable for the fitness of any materials furnished by
Customer unless directed by Customer, at additional cost to Customer, to make
corrections, repairs, or substitutions Printer deems necessary.  In no event
does Printer assume responsibility for color fidelity of finished goods made
from film furnished by Customer, unless proofed by Customer to Printer's
requirements.

     8.  Responsibility for Content; Right to Rescind.  Customer warrants that
         --------------------------------------------                         
any matter it furnishes for printing pursuant to this Agreement does not
infringe any copyright or trademark, is not libelous, and does not otherwise
violate any law or infringe the rights of any third party.  Customer agrees to
indemnify and hold Printer harmless against all losses, claims, damages,
liabilities and expenses, including Printer's attorneys' fees, which Printer may
incur as the result of any claims of such violation or infringement.  Printer
shall have the right, without liability of any kind to Customer, to refuse to
print any publication containing material that, in Printer's good faith
judgment, may give rise to such claims.

     9.  Business Reply Mail.  Customer shall be responsible for complying with
         -------------------                                                   
all postal service requirements concerning business reply mail; and Printer
shall not be liable to Customer for any damages or claims whatsoever in the
event that business reply mail is rejected by the postal service.

     10. Quantity Variation.  Variations in quantity of 0% over and 0% under
         ------------------                                                 
quantities ordered shall constitute acceptable delivery; and the excess or
deficiency shall be charged or credited at the "additional thousands" rate set
forth in the Price Schedule.

     11. Warranty.  Printer warrants that its services shall be performed
         --------                                                        
according to the terms of this Agreement and S W O P standards acceptable in the
printing industry.  However, due to differences in equipment, paper, inks, and
other conditions between the color proofing and production pressroom operations,
a reasonable variation in color between color proofs and the completed job, and
a reasonable variation on press, may exist.  Work containing such variations
shall be considered in conformity with this warranty.  Customer however,
retains, sole and absolute discretion in determining whether standards of
quality are sufficient.  In the event Customer reasonably concludes performance
of Printer is inadequate, then Customer may, with 30 days written notice, remove
affected publication(s) from Printer without penalty to Customer.

     12. Risk of Loss.  The risk of loss of finished work shall pass to the
         ------------                                                      
Customer F.O.B. the facilities at which the same was printed, upon the earlier
of Printer's delivery to carrier or postal service, or delivery into storage,
regardless of whether the transport medium or storage facilities are owned
and/or operated by Printer.  The risk of loss of property furnished and/or owned
by Customer shall be on the Printer while such property is at the facilities at
which the printing is to occur.  Customer shall bear the risk of loss while
property is in transit to and from Printer's facilities.

     13. Passage of Title.  Title to finished goods shall pass to Customer upon
         ----------------                                                      
the earlier of Printer's delivery to carrier or postal service, or delivery into
storage, regardless of whether the
<PAGE>
 
                                      -4-

transport medium or storage facilities are owned and/or operated by Printer.
Artwork, drawings, sketches, dummies, film positives, negatives, and separations
furnished by Printer shall become the property of Customer upon completion of
printing and payment therefor; provided, however, that if such items are
furnished by Printer by subcontracting the production thereof, then title
thereto shall pass to Customer upon shipment to Printer. All printing plates
shall be and remain the property of Printer.

     14. Storage.  Customer's materials which are in film form shall be stored
         -------                                                              
without charge for a period of 12 months from the time of last use and
thereafter destroyed.  If Customer's materials other than film are not shipped
within 24 hours after notification to Customer that they are ready to be
shipped, for any reason beyond Printer's reasonable control, including but not
limited to Printer's retention of such materials pursuant to Section 18 below,
Printer may store such materials at Customer's risk in a warehouse or at the
facilities at which printing occurred, and Customer shall pay all resulting
handling, transportation and storage charges as invoiced by Printer.

     15. Customer Furnished Paper.  If Customer furnishes paper, Printer agrees
         ------------------------                                              
to provide storage, at no cost to Customer, for up to two (2) months supply.
Inventory levels exceeding two (2) months supply are subject to storage charges
which are included in the Price Schedule.

     16. Contingencies.  Printer shall not be liable for any delay or failure
         -------------                                                       
to perform under this Agreement if such delay or failure to perform arises out
of causes beyond its reasonable control, including but not limited to labor
trouble, fires, severe weather and other acts of God, accidents, governmental
acts and regulations, inability to obtain materials or carrier space or
equipment, or delays of suppliers or carriers.  Printer shall give notice to
Customer of any such condition within a reasonable time after it arises.

     If Printer's operations are suspended for any of the above causes, Printer
shall have the right to have the work performed by one of its subsidiaries on
the same terms and conditions set forth in this Agreement.

     If Printer is unable for any reason to have the work done by one of its
subsidiaries, Customer shall have the right to have the services covered by this
Agreement performed elsewhere, and to remove from Printer's plant any and all
completed work, proofs, film, paper and other material and uncompleted work only
upon payment to Printer for all services rendered and materials furnished or
ordered by Printer prior to the date of suspension of operations.

     The parties agree that when Printer resumes operation, upon 30 days'
written notice to Customer, production shall resume and continue at Printer's
facilities under the terms and conditions of this Agreement.

     17. Claims.  All claims for defective or damaged product or for shortages
         ------                                                               
must be made by Customer in writing fully setting forth the nature of the
alleged defect, damage or shortage, within 30 days after Customer's receipt
thereof.  Customer's failure to so notify Printer shall constitute irrevocable
acceptance of the product and a waiver of any claim of defect,
<PAGE>
 
                                      -5-

damage or shortage. Claims for damage or loss in transit must be made by
Customer directly against the carrier.

     18. Limitation of Remedies.  Customer's sole and exclusive remedy for
         ---------------------                                           
Printer's negligence or other tort, breach of warrant or contract or any other
claim arising out of or connected with to that portion of the work which is
nonconforming or, at Printer's option, printing of a correction in subsequent
work, if applicable.

              IN NO EVENT SHALL PRINTER BE LIABLE FOR ANY SPECIAL,
              INDIRECT OR CONSEQUENTIAL DAMAGES, WHETHER FOR BREACH OF
              CONTRACT OR WARRANTY, NEGLIGENCE OR OTHER TORT OR ON ANY
              STRICT LIABILITY THEORY.

     19. Printer's Security Interest and Rights Upon Customer's Default.  If
         --------------------------------------------------------------     
any amount due Printer from Customer shall remain unpaid at the due date, or if
Customer defaults in the performance of any other covenant or condition of this
Agreement or any other agreement with Printer, Printer shall have the right to
terminate its obligations under this Agreement, to declare immediately due and
payable all obligations of the Customer for the work theretofore furnished by
the Printer under this Agreement, to retain possession of any product or
materials owned by Customer (including but not limited to work-in-process and
undelivered work) pending payment in full of all such obligations, to change
credit terms with respect to any further work furnished by Printer, and/or to
suspend or discontinue any further performance for Customer until overdue
amounts are paid in full and until cash or security satisfactory to Printer
covering further work, as may be require by Printer, is deposited in advance
with Printer.  These rights of Printer shall be in addition to and not in
substitution for any other rights of Printer; and suspension or discontinuance
of work by Printer pursuant to this Section shall not in any way prejudice any
claim or right of action which Printer may have by reason of any breach of this
Agreement or any other agreement by Customer.

     20. Right to Assurance.  Whenever either party in good faith has reason to
         ------------------                                                    
question the ability or intent of the other party to perform, the party having
such question may demand in writing adequate assurance from the other party of
its ability or intent to perform, and may suspend performance under this
Agreement pending such assurance.  In the event that such a demand is made and
such assurance is not given within a reasonable time, the party having made such
demand may treat that failure as an anticipatory repudiation of this Agreement
and exercise any appropriate remedy for repudiation.

     21. Bankruptcy.  If either party makes an assignment for the benefit of
         ----------                                                         
creditors, or admits in writing its failure or inability to pay its debts as
they become due, or becomes the subject of an "order for relief" within the
meaning of that phrase in the U.S. Bankruptcy Code, or applies for or consents
to the appointment of a receiver for any of its property, the other party may
terminate this Agreement at any time, effective immediately upon notice.  Such
termination 
<PAGE>
 
                                      -6-

December 20, 1994


Ms. Adele Hartwick, Treasurer and Controller
Advanstar Communications
131 W. Ist St.
Duluth MN 55802

Dear Adele:

I have taken the opportunity to summarize our conversation from last- Friday and
to outline how Advanstar's account will be administered beginning in 1995.  If
you have any question with an of the points below, please call me as soon as
possible.

1.   Effective January 1, 1995, Advanstar's credit terms will be changed from
     2%-10 days, Net 30 to "Cash in Advance".

2..  In consideration of cash in advance terms, Banta will abate the contractual
     2% manufacturing price increase.

3.   Since payments are to be made in advance, the 2% early pay discount will be
     reflected in Advanstar's new (1995) price schedules.

4.   Payment amounts will be broken down into equal weekly payments which are to
     be received every Friday beginning on December 30, 1994.

5.   Initial weekly payments, which include both production and postage, have
     been set at $125,000 tone Hart Press and $60,000 to Clark Printing Company.

     6.  Advanstar's account will be reviewed monthly.  Changes, if any, to the
     weekly payment will be assessed through anticipated production and
     reconciliation of payments to actual invoices.  Within Banta, this will
     have to be a coordinated effort with Jim Robison Sales Representative,
     Customer Service, and the Controllers at both plants (Dave Wampole - The
     Hart Press and Phil Zuptich - Clark Printing Co.).

You and I will need to remain in contact as these payment amounts are
determined.  I will ask both Dave and Phil to provide appropriate support for
their recommended payment amounts.

Scott A. Szybilski

THE DESERT INN ARTERIAL CONSTRUCTION COULD BE IN PROGRESS WHICH MAY HAVE AN
EFFECT ON THE PREMISES AND/OR THE PARKING AROUND THE PREMISES.  THE LESSEE
EXPRESSLY ACKNOWLEDGES THAT THIS CONSTRUCTION WORK COULD INTERFERE WITH ITS
TENANCY.

2.   CONDITIONS:  This Lease Agreement shall have no force or effect whatsoever
unless and until executed by both parties, to wit:  the Lessee and the President
of the LVCVA or his designee.  Lessee covenants and agrees to well and truly
perform and abide by each and every term, condition, limitation and restriction
herein set forth, each of which shall be a condition subsequent to the effect of
this Lease Agreement.  Any alteration to this document unless executed by both
parties will void this Lease Agreement.

The use of the facilities of the Las Vegas Convention Center herein described
includes corridors necessary to accommodate patrons and seating in or a part of
such facilities, together with such regularly provided heat, electrical power,
air conditioning, water and light, as may be required for use of said
facilities.  Concourse and entrance plaza areas are a leased portion of the
premises that must be used concurrently with other shows, and within certain
guidelines set forth from time to time by the Las Vegas Convention Visitors
Authority.  Exhibit floor plan must be approved by LVCVA's Fire Safety
Coordinator before sale of exhibit space to prospective exhibitors.   Carpeted
areas will

                                      -3-

be protected when used for exhibits whether commercial or non-commercial. The
Lessee shall not permit the demised premises to be used for lodging rooms or for
any improper, immoral, illegal or objectionable purpose. The LVCVA reserves the
right to use meeting rooms during move-in and move-out period and show days
after show hours when Lessee is not using the same, such as at night, so long as
rooms are in proper order as and when required by Lessee. LVCVA will hold Lessee
harmless if the LVCVA uses meeting rooms when Lessee is not using the same.
LVCVA will not use meeting rooms assigned to Lessee for Lessee office space.
Lessee shall not be liable under any provisions herein provided should any loss
or damage occur during such period of time so used by a person or entity other
than Lessee. The Lessee will be given notice and a reasonable opportunity to
cure any default in their obligation under this case. The President of the LVCVA
will have the final authority but must act reasonably, to determine the
appropriate action relating to any default under this lease.

If Lessee or any exhibitor so desires, upon written order of Lessee, the LVCVA
will cause electric, gas or water service or connections to be installed,
adjusted or effected as follows:

ELECTRICITY:  One-half normal illumination will be allowed for move-in and move-
out days.  Additional lighting, heating and air conditioning requested by the
Lessee will be assessed a charge based on actual usage.  Full illumination will
be permitted on day prior to show opening.  The LVCVA agrees to make available
to Lessee, through its agent (electrical contractor) up to its existing
capacity, all electric power required, and the Lessee agrees that any agreement
with its agent (electrical contractor) will require said agent (electrical
contractor) to reimburse the LVCVA with a fifteen (15) percent surcharge on the
regular electric outlet rental fee charged exhibitors on all electric outlets
and floodlight charges levied by Lessee or its agent (electrical contractor) to
exhibitor on all power made available by the LVCVA.  All electrical service
provided to Association spaces will be included when calculating charges.
Lessee further agrees that its agent (electrical contractor) will supply the
LVCVA with duplicate copies of all electrical charges made by said agent
(electrical contractor) to each exhibitor within thirty (30) days after
expiration of the Lease Agreement for the purpose of verifying the fifteen (15)
percent surcharge amount to be paid the LVCVA by said agent (electrical
contractor) and upon said agent's (electrical contractor) failure to pay said
amount, then Lessee hereunder agrees to pay the same to the LVCVA upon
submission of the documentation supporting a statement for the amount due LVCVA
hereunder.

GAS AND PLUMBING:  At Lessee's expense, at the standard rate for connection and
consumption of gas or water, as per schedule to be established from time to time
by the LVCVA in accordance with the LVCVA's prevailing practice, and Lessee
shall be responsible for all charges arising from such contracts.  Lessee shall
be responsible for expenses incurred by the LVCVA for Lessee or its exhibitors
for which the LVCVA has accepted a written order from the Lessee.  The above and
foregoing approval shall apply to subcontractor(s) as well as contractors.

Lessee, and its sublessees, any telecommunications, newsstand, gift shop and
business center services including normal telephone services; cellular telephone
services; facsimile; copies; secretarial; baggage holding; small package
freight; business equipment; and any other services associated with
telecommunications, newsstand, gift shop or business center activities.  The
Lessee, or its Sublessee, shall have no right to contract out these services.
The exclusion for gift shop goods and services shall not include the sale of

4.   FORFEITURE:  If cancellation is made (either partial or complete
cancellation), then the non-refundable advance deposit amount called for on page
1 shall be forfeited by the Lessee in consideration of the LVCVA holding said
dates for exclusive use of the Lessee and rendering the same unavailable for
others and as liquidated damages therefore.  The Lessee further covenants that
if any default is made in payment of the rent or any part thereof at the times
above specified, or if any default is made in the covenants or agreements herein
contained, this rental of the facilities at the option of the LVCVA shall cease
and terminate, and of the parties shall be the same in all respects as if said
term had fully expired.  The LVCVA may reenter the said premises and hold the
same as of its former sate therein, removal all persons therefrom and resort to
any legal proceedings to obtain such possession.  The Lessee shall
notwithstanding such reentry, pay the full amount of said rental as herein
agreed to be paid.  If cancellation is made by Lessee less than three years
before show date, Lessee agrees to pay, as liquidated damages, twenty-five
percent (25%) of the minimum daily rate for the total number of show days on
lease.  If cancellation is made by Lessee less than two years before show date,
Lessee agrees to pay, as liquidated damages, fifty percent (50%) of the minimum
daily rate for the total number of show days on lease.  If cancellation is made
by Lessee less than one year before show date, Lessee agrees to pay, as
liquidated damages, one hundred (100%) of the minimum daily rate for the total
number of show days on lease.  The LVCVA will make all reasonable efforts to re-
lease the Leased Premises upon written notification of the Lessee's default, but
any such re-lease shall not serve to relieve the Lessee from the payment of the
above referenced liquidated damages.  The liquidated damages provisions in this
paragraph are a consequence of the fact that the amount of actual damages
resulting from Tenant's termination is impossible to ascertain.  Any liquidated
damages paid by the Tenant is not to be construed as a penalty.

LVCVA at least thirty (30) days prior to the time of occupancy herein provided a

contractor) to reimburse the LVCVA with a fifteen (15) percent surcharge on the

provided to Lessee spaces will be included when calculating charges.  Lessee
further agrees that its agent (electrical contractor) will supply the LVCVA with
duplicate copies of all electrical charges made by said agent (electrical
contractor) to each exhibitor within thirty (30) days after expiration of the

<PAGE>
 
                                      -4-

telecommunications, newsstand, gift shop or business center activities.  The
Lessee, or its sublessee, shall have no right to contract out these services.

show merchandise.

4.  FORFEITURE:  If cancellation is made (either partial or complete
cancellation), then the non-refundable advance deposit amount called for on page
1 shall be forfeited by the Lessee in consideration of the LVCVA holding said
dates for exclusive use of the Lessee and rendering the same unavailable for

above specified, or if any default is made in the covenants or agreements herein
contained, this rental of the facilities at the option of the LVCVA shall cease
and terminate, and the relation of the parties shall be the same in all respects

to re-lease the Leased Premises upon written notification of the Lessee's
default, but any such re-lease shall not serve to relieve the Lessee from the
payment of the above referenced liquidated damages.  The liquidated damages
provisions in this paragraph are a consequence of the fact that the amount of

agent of the Lessee and receive the rent therefrom, applying the same first to
payment of such expenses as may be incurred in reentering and reletting said
premises and then to the payment of the rent due by these presents; the surplus,
if any, is to be paid over to the Lessee, and Lessee covenants that charges
herein agreed to be paid remaining after deducting the net rental resulting from
such reletting shall be paid by Lessee. However, nothing herein contained shall
be construed as imposing any obligation on the LVCVA to so relet or attempt to
relet the said premises or in any way affect the obligation of the Lessee to pay
the full amount of said rental in case said premises shall not be so relet.

SECTION 2.1    LICENSE OF AUTHORIZED AREA.  The Licensor hereby licenses the use
by the Licensee of the Authorized Area during the License Period only for the
use and purpose and upon the terms and conditions set forth in this Agreement
and only for the hours of operation indicated herein and the Licensee hereby
agrees to the use of the Authorized Area during the License Period only for the
use and purpose and upon the terms and conditions set forth in this Agreement.

SECTION 2.2    PROHIBITED USES.  The Licensee shall not use or allow the

the Facilities; in any manner which constitutes waste or nuisance; in any manner
which causes damage to the Facilities, including, without limiting the
generality thereof, driving any nails, hooks, tacks, screws or other devices
into any part of the Facilities or affixing any matter thereto by paste, tape or
other adhesive or altering the Facilities in any respect without the prior
written approval of Licensor; or in violation of the Facilities Rules and
Regulations as such may exist from time to time. The propriety or morality of
any use of the Facilities or Authorized Area by the Licensee shall be determined
in light of the community standards and based on the reasonable good faith
assessment of the Licensor after consultation with the Licensee.

SECTION 2.3    DEVELOPMENT OF PLAN OF OPERATION UNDER LICENSE.  The Licensee
shall provide the Licensor, at least ninety (90) days prior to the beginning of
the License Period, all information then reasonably available to the Licensee
pertinent to the activities to be undertaken in the Authorized Area pursuant to
the License (herein "plan of operation"), including but not limited to:

(i)   Floor plans.  (4 copies) indicating the design, nature and proposed
location of all exhibits and meeting space;

(ii)  Utility and construction plans, including plans of all intended rigging;

(iii) All certificates of insurance required hereunder;

(20) days of the receipt of the plan of operation, to require the Licensee to
make such changes, deletions, and additions to the plan of operation as the
Licensor may reasonably deem necessary or desirable for the purpose of insuring
the safe and orderly operation of the Facilities and the Authorized Area.
Failure by the Licensee to make any such changes, additions, or deletions
required by the Licensor within ten (10) days after such notice shall constitute
an Event of Default as set forth in Article VIII.

SECTION 2.4    LICENSOR'S CONTROL AND RIGHT OF ENTRY.  In permitting use of the
Authorized Areas by the Licensee, the Licensor retains and does not relinquish
the right to issue and enforce such rules, regulations and directives as it may
deem necessary for the safe, orderly and commercially sound operation of the
Facilities. The Licensor and its authorized representatives may enter the
Authorized Area after giving prior notice to Licensee, for the purpose of
inspecting and checking the same and the uses thereof; of making necessary
repairs thereto; adjusting apparatus or equipment therein; of abating waste,
nuisances or violations of law or Rules and Regulations promulgated by the
Licensor; of preparing food or readying other concessions; and of ejecting any
objectionable person or persons from therein. The Licensee agrees that it will
not allow any person at, in or about the Facilities who shall, upon reasonable,
non-discriminatory grounds, be objected to by the Licensor and such person's
right to use the Facilities and the Authorized Area therein may be revoked by
the Licensor.

          ARTICLE III - PAYMENT OF FEES, COSTS, CHARGES AND DEPOSITS

SECTION 3.1    The Licensee shall (in addition to the Basic Fee including

transfer.

SECTION 3.2    The Licensee shall pay to the Licensor all Basic Fees including
Reservation Fees, and Additional Fees as set forth in Article I and Article IV.

Charges are non-refundable, except as specifically provided in this Agreement.
Licensee acknowledges that all deposits are not refundable and that payments
made pursuant to the liquidated damage provisions set forth in Section 8.6 are
fair and reasonable consideration for Licensor's holding the Authorized Areas
for the dates indicated for the exclusive use of Licensee and rendering the same
unavailable for others. The Licensor shall have no obligation to the Licensee to
pay interest on any fees or deposits, and the Licensor shall have the right to
commingle such monies with the Licensor's other funds.

SECTION 3.4    Any payment required hereunder not paid when due shall bear
interest at the rate of eighteen (18%) percent per annum from the date due and
shall be payable forthwith on demand by the Licensor. This right to collect
interest does not preclude the Licensor from asserting any other rights against
the Licensee, including, but not limited to, those set forth in Article VIII.

Licensee reasonably claims to be in dispute; provided, however, that Licensee
pays all undisputed amount when due.

SECTION 4.2    CONTRACTUAL SERVICES NOT INCLUDED IN BASIC FEE.  For all

exhibitors or other invitees when holding or participating in the Event. For
purposes of this Agreement, "Authorized Contractor" means those persons who

or if a service is provided for which no rate is stated, then Licensee shall pay
Licensor at a rate to be agreed upon. Licensee shall provide Licensor with
notice of the Exclusive Contractual Services it requires when it files its plan
of operation in accordance with Section 2.3. Authorized Contractors shall bill
Licensee directly at rates agreed to by them and payment shall be made directly
to the Authorized Contractor. All bills for Contractual Services rendered by
Licensor or Authorized Contractors to Licensee's exhibitors or invitees shall be
rendered to and paid directly by the exhibitor or invitee. Licensor shall be
under no obligation to provide a Contractual Service unless it or an Authorized
Contractor is reasonably capable of providing the service. No Contractual
Services shall be utilized or employed by Licensee except as provided in this
Section 4.2 or as approved in advance in writing by Licensor. To facilitate
Licensor's provision of Contractual Services hereunder, Licensee is requested to
provide Licensor, at least 120 days prior to the beginning of the License
Period, with a list of all exhibitors or other invitees planning to use the
Authorized Areas during the License Period, with the business address, telephone
number and name of the appropriate person to be contacted at each such exhibit.

remain in the Facilities after it has closed.

SECTION 4.4    REGISTERED NURSE OR OTHER MEDICAL PERSONNEL.  The Licensee shall
maintain at the Facilities at all times during the show period a registered
nurse or other medical personnel (at Licensor's direction), fully licensed as

the Licensor's exclusive service provider for such services.

times shall have, the sole right to operate or have operated in its behalf all
commercial enterprises, including all concessions, bars and catering operations
and to sell or otherwise provide flowers, food, refreshments, beverages, cigars,
cigarettes, candies and periodicals, and to grant concessions to designated
airlines, auto rentals, delivery services and others. The Sands Expo and
Convention Center and the adjoining hotel complex, to be named at a later date,
offer a full range of food, beverage, function, and hospitality services both at
the Facilities and the Hotel. Licensee agrees to designate the Hotel as an
official headquarters location in all pre-show direct mail and advertising where

the prior approval of the Licensor. If such approval is granted by Licensor,
Licensee shall pay the Additional Fee as set forth on Exhibit CS. Any signage to
be posted or exhibited in any area of the Facilities other than the Authorized
Areas shall be upon the regular billboards, if any, provided by the Licensor
therefore. The Licensee will use, post or exhibit only such signage as it
related to the Event in the Authorized Areas and during the hours for which this
License was granted and for such period of time designated by the Licensor.

SECTION 4.7    USE OF LICENSOR'S EQUIPMENT.  Any equipment provided by the
Licensor to the Licensee which requires an operator or technician, such operator
or technician may, if required by the Licensor, be supplied by it to operate

in Article I, the Licensee agrees that the same will be paid on the date set
forth in Article I, and that the Licensor shall hold the same throughout the
License Period as security for the performance by the licensee of all
obligations on the part of the Licensee hereunder. The Licensor shall have the
right from time to time, without prejudice or any other right or remedy the
Licensor may have hereunder or by law, to apply, without notice to the Licensee,
such deposit, or any part thereof, to the Licensor's damages arising from any
Event of Default caused by the Licensee or to pay any of the Licensee's
obligations for any of the Exclusive Contractual Services contracted for by the
Licensee pursuant to Article IV. If the Licensee is not in default under this
Agreement at the time of final accounting, the Licensor shall return the
Security Deposit, or so much thereof as shall not theretofore have been applied
in accordance with the terms of this Section 5.1, to the Licensee.

will give written notice to Licensor at least thirty (30) days prior to any
material change in, cancellation, or non-renewal of the policy. Licensee's
failure to provide such certificates or policies, as the case may be, within the

obligations hereunder.
<PAGE>
 
                                      -9-

(b)  The Licensee shall obtain and maintain during the License Period insurance

deductible per loss of not more than $1,000.00.

SECTION 6.2    INDEMNIFICATION AND HOLD HARMLESS AGREEMENT.

(a)  The Licensee hereby releases and discharges and indemnifies, and agrees to
keep indemnified, defend, protect and save harmless the Licensor and those named
Additional Indemnities set forth in Article I (herein "Indemnities") of and from
any and all claims, demands, liabilities, damages, costs, losses and expenses
(including attorneys' fees) for any injury to, including death (whether they be
third persons or employees of either the Licensor or Licensee) and any loss
(through theft or otherwise) of or damage to property (whether it be that of the
Licensor or the Licensee or a third person) caused by, growing out of, or
happening in connection with or with respect to the use by the Licensee, or of
any other person or legal entity with the permission (express or implied) of the
Licensee, of the Facilities or its equipment. Such indemnification by the
Licensee shall apply unless such damage or injury results from the sole
negligence, gross negligence or willful misconduct of the Licensor or any person
contracted or hired by Licensor to perform Exclusive Contractual Services.

(b)  Without limiting the foregoing, the Licensee assumes all costs and expenses
arising from the use of patented, trademarked, or copyrighted materials,
equipment, devices, processes, or dramatic rights used during or incorporated in
the conduct of its operation hereunder; and the Licensee agrees to indemnify and
hold harmless the Indemnities from all damages, costs and expenses at law or for
equitable relief for or on account of any patented, trademarked or copyrighted
materials, equipment, devices, processes or dramatic rights furnished to or used
by the Licensee or its exhibitors, or any infringement with respect thereto in
connection with this License, including the costs and expenses in defending any
such action, even if it be groundless or fraudulent.

(c)  Without limiting the foregoing, the Licensee shall also indemnify and save
harmless the Indemnities from all claims, demands, liabilities, damages, costs,
losses and expenses made against or incurred by any of the Indemnities arising
out of injury or loss to third parties caused by Licensee's failure to return
the Authorized Area to the Licensor, vacate the Facilities, relinquish the
Licensor's or Authorized Contractor's equipment at the end of the License
Period, or Licensee's breach of any contract or agreement with a third party to
provide contractual or other services.

SECTION 6.3    WAIVER OF SUBROGATION.  The Licensee hereby waives any and every
claim which arises in its favor and against the Licensor, against any of the
Additional Indemnities set forth in Article I, for any and all loss or damage
covered by valid and collectible insurance policies to the extent of the
insurance proceeds paid with respect thereto. Such waiver shall be in addition
to, and not, in derogation of, any other waiver or release contained in this
License with respect to any loss or damage to property of the Licensees.
Inasmuch as the waiver will preclude the assignment of any aforesaid claim by
way of subrogation (or otherwise) to an insurance company (or any other person),
the Licensee shall notify its insurers of such waiver.

         ARTICLE VII - LICENSEE'S OBLIGATION AT END OF LICENSE PERIOD

SECTION 7.1    RETURN OF AUTHORIZED AREA.  At the end of the License Period, the
Licensee shall vacate the Facilities and return the Authorized Area and the
Licensor's equipment to the Licensor, all in the same broom clean condition and
repair as originally furnished to the Licensor, normal wear and tear excepted.
At such time, the Licensee shall remove completely from the Facilities all
goods, wares, merchandise and property of any and all kinds and description
placed therein (herein "Property").

SECTION 7.2    REPAIR OF AUTHORIZED AREA.    The Licensee agrees that if the
Authorized Area, or any other part of the Facilities, shall be damaged by the
act, default or negligence of the Licensee, or the Licensee's agents, employees,
patrons, guests or invitees, the Licensee will pay to the Licensor upon demand
such sum as shall be necessary to restore said areas to their present condition
at the commencement of the License Period. The Licensee hereby assumes full
responsibility for the character, acts and conduct of all persons acting for or
on behalf of said Licensee.

SECTION 7.3    FAILURE TO RETURN THE AUTHORIZED AREA OR VACATE THE FACILITIES. 
In the event the Licensee shall fail to return the Authorized Area to the
Licensor or to vacate the Facilities in accordance with the provisions of
Section 7.1, the Licensor is authorized, at the Licensee's expense, to remove
therefrom and to store or return to the Licensee or, except where the Licensee's
failure to do so is caused by an event beyond the Licensee's control, such as a
strike beyond its control, a national emergency or an Act of God, to treat the
same as abandoned and discarded property and accordingly dispose of the
Property. The Licensor shall not be liable for any damages or loss to the
Property which may be sustained either in the course of such removal or in the
course of storage, or in the course of transit, or by virtue of the Licensor's
disposal of the Property and the Licensor is hereby expressly released from any
and all such claims for damages of whatsoever kind or nature. The Licensor shall
be under no duty, however, to so remove, store or return the Property.

SECTION 7.4    EXTENDED USE CHARGE.  The Licensee shall pay an Extended Use

day or portion of a day after the end of the License Period that the Licensee
has failed to return all or any part of the Authorized Area to the Licensor and
vacate the Facilities in accordance with the provisions of Section 7.1, unless
said failure is caused by any of the following events, to the extent that such
event is beyond the Licensee's reasonable control: fire, flood, riot,
earthquake, civil commotion or Act of God. The liability to pay an Extended Use
Charge does not in any way extend the License Period; is not liquidated damages;
intended as a penalty against the Licensee for use of the Facility or the
Authorized Area beyond the License Period; and does not preclude the Licensor
from asserting any other rights against the Licensee, including, but not limited
to, those set forth in Section 7.3 and Article VII. The Extended Use Charge is
due and payable at the end of each day for which the Charge is assessed.

SECTION 7.5    FAILURE TO COMPLY LIST.  Licensor and Licensee shall conduct a
walk through of the Authorized Area within forty-eight (48) hours of the end of
the License Period for the purpose of

the provisions of Section 7.1 no later than the earlier of the following:

(i)   Seven (7) days after the end of the applicable License period, or;

(ii)  The commencement of any use of the hall or any portion of the Authorized
Area by any person other than the Licensee. The Licensee shall not be
responsible for any alleged non-compliance with Section 7.1 not specifically
identified in the list.

                      ARTICLE VII - DEFAULT AND REMEDIES

SECTION 8.1    EVENTS OF DEFAULT.  The occurrence of any of the following shall

taxes when due or fail, upon request of the Licensor, to provide evidence of the
same to the Licensor;

relief for itself under any present or future Federal, State or other statute,
law or regulation for the relief of debtors, shall seek or consent to or

other law seeking any reorganization, arrangement, composition, readjustment,
liquidation, dissolution, or similar relief.

(g)  Licensee shall materially diverge from the plan of operation without the
prior written consent of Licensor.

SECTION 8.2    LICENSOR'S REMEDIES UPON EVENT OF DEFAULT.  Upon the occurrence
of any of the Events of Default set forth in Section 8.1 elsewhere in this

<PAGE>
 
                                     -12-

(d)  enter and take exclusive possession of and remove all persons and property
from the Authorized Areas and the Facility;

(e)  assert and enforce claims against any bond provided under this Agreement,
or

(f)  refuse to commence, or discontinue the rendition of all services or
utilities to Licensee and the Authorized Areas.

Licensee waives any right it may have as to notice or hearing prior to the
exercise of the powers set forth above. The rights and remedies of Licensor
shall be cumulative, and none shall exclude other rights or remedies allowed by
law or at equity, or set forth in other sections of this Agreement.

SECTION 8.3    REMEDYING DEFAULTS.  The Licensor may, but shall not be required
to, pay such sums or to do any act which requires the expenditure of monies or
services which may be necessary or appropriate by reason of the failure or
neglect of the Licensee to perform any of the provisions of this License. In the
event of the exercise of such right by the Licensor, the Licensee agrees to pay
the License forthwith upon demand all sums expended by the Licensor (or the fair
value thereof, whichever is greater), together with interest there at the rate
of eighteen (18%) percent per annum, as an Additional Charge.

SECTION 8.4    TERMINATION WITHOUT DEFAULT.  In the event that the Authorized
Area or the Facilities of which is a part or any portion thereof are destroyed
or damaged by fire or other casualty so that in the reasonable judgment of the
Licensor its or the Licensee's use thereof would be substantially interfered
with, or in the event of a taking of all or a portion of the Facilities by
eminent domain, condemnation or foreclosure, then the Licensor may terminate
this Agreement upon giving to the Licensee notice of termination not more than
ninety(90) days following the event of destruction, damage or taking and this
Agreement shall terminate on the date set forth in such notice of termination,
all with the same force and effect as though the License Period of this
Agreement had originally been scheduled to expire on such date, and Licensor
shall return to the Licensee all monies theretofore paid by the Licensee to the
Licensor as a Security Deposit, Reservation Fee, Basic Fee, or Additional Fee.

SECTION 8.5    RIGHT TO RE-ENTER.  If this License shall have been terminated as
provided in this Article, or if any execution or attachment shall be issued
against the Licensee or its Property whereupon the Authorized Area shall be
taken or occupied by someone other than the Licensee, then the Licensor may,
without notice, re-enter the Authorized Area, without being liable for any
prosecution thereof, and remove the Licensee and all other persons and any and
all property from the same, as if the License was not in effect.

SECTION 8.6    LIQUIDATED DAMAGES.  The parties agree that, if the Licensee
shall cancel the Event covered by this License, the damages that would be
suffered by the Licensor, including all of the ancillary revenues that would be
lost, are presently difficult to estimate and therefore in case of such
cancellation, the Licensor shall retain or the Licensee shall pay to the
Licensor, as the case may be, the Reservation Fee, the remainder of the Basic
Fee set forth in Article I and any Additional Fees and Additional Charges, all
as liquidated damages and not as penalty.

SECTION 8.7    LIENS.  To secure the Licensee's obligation hereunder, Licensee
hereby grants the Licensor the first right of lien against all ticket office
receipts and Property of the Licensee hereunder. The Licensor is empowered to
withhold from ticket office receipts such amount is outstanding and owed by the
Licensee hereunder. If the total ticket office receipts are insufficient to
cover such unpaid amounts the Licensor shall have the right to impound the
Licensee's Property at the Facilities, or elsewhere, at the Licensee's expense.
If such unpaid amounts remain unpaid for a period of ten (10) days after the
termination of this License, the Licensor shall have the right to sell the
impounded Property at public auction and to apply the cash proceeds from the
auction less its cost, including attorneys' fees, to the retirement of said
unpaid amounts.

SECTION 8.8    ACTIONS.   Any actions by one party to this License against
another arising hereunder shall be maintained in the State of Nevada; and the
Licensee hereunder consents to same and to the maintenance of such action by the
Licensor against it in said State of Nevada.

SECTION 8.9    CUMULATIVE REMEDIES.  All rights, powers and privileges contained
hereunder upon the Licensor shall be cumulative and shall not be restricted to
those given by law.

SECTION 8.10   FORCE MAJEURE.  In the event that the Licensor's obligations to
the Licensee under this Agreement be delayed, prevented rendered impractical by
any of the following events: fire, flood, riot, earthquake, civil commotion,

to, and not, derogation of, any other waiver or release contained in the License
with respect to any loss or damage to property of the Licensees.  Inasmuch as
the waiver will preclude the assignment of any aforesaid claim by way of
subrogation (or otherwise) to an insurance company (or any other person), the
Licensee shall notify its insurers of such waiver.

Licensee shall pay Licensor at a rate to be agreed upon by the parties.
Licensee shall provide Licensor with notice of the Contractual Services it
requires when it files its Plan of Operation in accordance with Section 2.3.
Authorized Contractors shall bill Licensee directly at rates agreed to by them
and payment shall be made directly to the Authorized Contractor.  All bills for
Contractual Services rendered by Licensor or Authorized Contractors to
Licensee's exhibitors or invitees shall be rendered to and paid directly by the
exhibitor or invitee.  Licensor shall be under no obligation to provide a
Contractual Service it has specifically undertaken to provide unless it or an
Authorized Contractor is reasonably capable of providing the service.  The

Contractual Services shall be determined at the time the parties agree upon
Licensee's Plan of Operation.  No Contractual Service shall be utilized or
employed by Licensee except as provided in the Section 4.2 or as approved in

by the Licensor or by any guard, watchman or protection service contracted for
by the Licensee.

the party whose organization, business or concern is advertising on the signs,
advertisements, show bills, banners, lithographs, posters, or cards.  Any

         ARTICLE V - SECURITY DEPOSIT AND PERFORMANCE BOND OR GUARANTY

SECTION 5.1  SECURITY DEPOSIT.  With respect to the Security Deposit specified
in Article I, the Licensee agrees that the same will be paid on the date set
forth in Article I, and that the Licensor shall hold the same throughout the
License Period as security for the performance by the licensee of all
obligations on the part of the Licensee hereunder.  The Licensor shall have the
right from time to time, without prejudice to any other right or remedy the
Licensor may have hereunder or by law, to apply, without notice to the Licensee,
such deposit, or any part thereof, to the Licensor's damages arising from an
Event of Default caused by the Licensee or to pay any of the Licensee's
obligations for any of the Exclusive Contractual Services contracted for by the
Licensee pursuant to Article IV.  If the Licensee is not in default under this
Agreement at the time of final accounting, the Licensor shall return the
Security Deposit, or so much thereof as shall not theretofore have been applied
in accordance with the terms of this Section 5.1, to the Licensee.

SECTION 5.2  PERFORMANCE BOND OR GUARANTY.  Upon request by the Licensor, the
Licensee shall furnish to the Licensor a performance bond or sufficient guaranty
in substance and amount determined by Licensor.

       ARTICLE VI - INSURANCE, INDEMNIFICATION AND WAIVER OF SUBROGATION

SECTION 6.1  INSURANCE.

(a)   The Licensee shall provide and keep in force during the License Period the
following insurance (in addition to any other insurance Licensor may deem
necessary):

(i)   Workers' compensation insurance in accordance with Nevada Law covering
Licensees' employees.

(ii)  Employers' Liability insurance for Nevada operations in minimum limits of
One Million Dollars ($1,000,000) per occurrence.

(iii) Commercial General Liability insurance including blanket contractual
liability and personal injury coverage with limits of Liability of at least One
Million Dollars ($1,000,000) in any one occurrence.

(iv)  Comprehensive Automobile Liability insurance insuring any owned, non-
owned, and hired vehicles to be used in and out of the "Facilities" in an amount
of One Million Dollars ($1,000,000) in any one occurrence.

All insurance required shall be issued by companies authorized to do business in
the State of Nevada.  Licensee shall have completed by its insurance agent the
Certificate of Insurance provided by Licensor and/or separate certificates for
Nevada Workers' Compensation.  Licensee shall deliver such completed
certificates of insurance to Licensor at least ninety (90) days prior to the
beginning of the License Period.  All required insurance policies shall name as
additional insured those entities set forth in Article I as "Additional Insureds
and Indemnities".
<PAGE>
 
                                      -10-

All required insurance policies shall provide that (i) the insurance carrier
will give written notice to Licensor at least thirty (30) days prior to any
material change in, cancellation, or non-renewal of the policy.  Licensee's
failure to provide such certificates or policies, as the case may be, within the
period specified herein shall constitute a breach of the Licensee's duties and
obligations hereunder.

(b)  The Licensee shall obtain and maintain during the License Period insurance
policies on all personal property owned, leased or hired by, or in the care,
control or custody of the Licensee during the License Period. Such policies
shall provide coverage for "all risks," including earthquake, flood and theft
with a deductible per loss of not more than $1,000.00.

SECTION 6.2  INDEMNIFICATION AND HOLD HARMLESS AGREEMENT.

(a)  The Licensee hereby releases and discharges and indemnifies, and agrees to
keep indemnified, defend, protect and save harmless the Licensor and those named
Additional Indemnities set forth in Article I (herein "Indemnities") of and from
any and all claims, demands, liabilities, damages, costs, losses and expenses
(including attorneys' fees and disbursements) for any injury to, including death
(whether they be third persons or employees of either the Licensor or the
Licensee) and any loss (through theft or otherwise) of or damage to property
(whether it be that of the Licensor or the Licensee or a third person) caused
by, growing out of, or happening in connection with or with respect to the use
by the Licensee, or of any other person or legal entity with the permission
(express or implied) of the Licensee, of the Facilities or its equipment. Such
indemnification by the Licensee shall apply unless such damage or injury results
from the sole negligence, gross negligence or willful misconduct of the Licensor
or any person contracted or hired by Licensor to perform Exclusive Contractual
Services.

(b)  Without limiting the foregoing, the Licensee assumes all costs and expenses
arising from the use of, broadcast, performance or publication, including
musical or other audio or visual presentation, of patented, trademarked, or
copyrighted materials, equipment, devices, processes, or dramatic rights used
during or incorporated in the conduct of its operation hereunder; and the
Licensee agrees to indemnify and hold harmless the Indemnities from all damages,
costs and expenses at law or for equitable relief for or on account of any
patented, trademarked or copyrighted materials, equipment, devices, processes or
dramatic rights furnished to or used by the Licensee or its exhibitors, or any
infringement with respect thereto in connection with this License, including the
costs and expenses of defending any such action, even if it be groundless or
fraudulent.

(c)  Without limiting the foregoing, the Licensee shall also indemnify and save
harmless the Indemnities from all claims, demands, liabilities, damages, costs,
losses and expenses made against or incurred by any of the indemnities arising
out of injury or loss to third parties caused by Licensee's failure to return
the Authorized Area to the Licensor, 
<PAGE>
 
                                      -11-

vacate the Facilities, relinquish the Licensor's or Authorized Contractor's
equipment at the end of the License Period, or Licensee's breach of any contract
or agreement with a third party to provide contractual or other services.

SECTION 6.3  WAIVER OF SUBROGATION.  The Licensee hereby waives any and every
claim which arises in its favor and against the Licensor, or against all of the
Additional Indemnities set forth in Article I, for any and all loss or damage
covered by valid and collectible insurance policies to the extent of the
insurance proceeds paid with respect thereto.  Such waiver shall be in addition
to, and not, derogation of, any other waiver or release contained in this
License with respect to any loss or damage to property of the Licensees.
Inasmuch as the waiver will preclude the assignment of any aforesaid claim by
way of subrogation (or otherwise) to an insurance company (or any other person),
the Licensee shall notify its insurers of such waiver.

          ARTICLE VII - LICENSEE'S OBLIGATION AT END OF LICENSE PERIOD

SECTION 7.1  RETURN OF AUTHORIZED AREA.  At the end of the License Period, the
Licensee shall vacate the Facilities and return the Authorized Area and the
Licensor's equipment to the Licensor, all in the same broom clean condition and
repair as originally furnished to the Licensee, normal wear and tear excepted.
At such time, the Licensee shall remove completely from the Facilities all
goods, wares, merchandise and property of any and all kinds and description
placed therein (herein "Property").

SECTION 7.2  REPAIR OF AUTHORIZED AREA.  The Licensee agrees that if the
Authorized Area, Lobbies, Hallways, Restrooms or other Public Space, or any
other part of the Facilities, shall be damaged by the act, default or negligence
of the Licensee, or of the Licensee's agents, employees, patrons, or invitees,
the Licensee will pay to the Licensor upon demand such sum as shall be necessary
to restore said areas to their condition immediately prior to the commencement
of the License Period.  The Licensee hereby assumes full responsibility for the
character, acts and conduct of all persons acting for or on behalf of said
Licensee.

SECTION 7.3  FAILURE TO RETURN THE AUTHORIZED AREA OR VACATE THE FACILITIES.  In
the event the Licensee shall fail to return the Authorized Area to the Licensor
or to vacate the Facilities in accordance with the provisions of Section 7.1,
the Licensor is authorized, at the Licensee's expense, to remove therefrom and
to store or return to the Licensee or, except where the Licensee's failure to do
so is caused by an event beyond the Licensee's control, such as a strike beyond
its control, a national emergency or an Act of God, to treat the same as
abandoned and discarded property and accordingly dispose of the Property.  The
Licensor shall not be liable for any damages or loss to the Property which may
be sustained either in the course of such removal or in the course of storage,
or in the course of transit, or by virtue of the Licensor's disposal of the
Property and the Licensor is hereby expressly released from any and all such
claims for damages of whatsoever kind or nature.  The Licensor shall be under no
duty, however, to so remove, store or return the Property.
<PAGE>
 
                                      -12-

SECTION 7.4  EXTENDED USE CHARGE.  The Licensee shall pay an Extended Use Charge
equal to twice the per diem Basic Fee applicable to Show Days for each day or
portion of a day after the end of the License Period that the Licensee has
failed to return all or any part of the Authorized Area to the licensor and
vacate the Facilities in accordance with the provisions of Section 7.1, unless
said failure is caused by any of the following events, to the extent that such
event is beyond the Licensee's reasonable control:  fire, flood, riot,
earthquake, civil commotion, or Act of God.  The liability to pay an Extended
Use Charge does not in any way extend the License Period; is not liquidated
damages; is intended as a penalty against the Licensee for use of the Facilities
or the Authorized Area beyond the License Period; and does not preclude the
Licensor from asserting any other rights against the Licensee, including, but
not limited to, those set forth in Section 7.3 and Article VIII.  The Extended
Use Charge is due and payable at the end of each day for which the Charge is
assessed.

SECTION 7.5  FAILURE TO COMPLY LIST.  Licensor and Licensee shall conduct a walk
through of the Authorized Area within twenty-four (24) hours of the end of the
License Period for the purpose of preliminarily identifying any failure of the
Licensee to comply with the provisions of Section 7.1.  In addition, Licensor
shall provide to Licensee a final, comprehensive and complete list of Licensee's
failure(s) to comply with the provisions of Section 7.1 no later than the
earlier of the following:  (i) seven (7) days after the end of the applicable
License Period or (ii) the commencement of any use of the hall or any portion of
the Authorized Area by any person other than the Licensee.  The Licensee shall
not be responsible for any alleged non-compliance with Section 7.1 not
specifically identified in the list.

                      ARTICLE VIII - DEFAULT AND REMEDIES

SECTION 8.1  EVENTS OF DEFAULT.  The occurrence of any of the following shall be
considered an "Event of Default":

(a)  The Licensee shall fail to pay in full and when due any payment required
hereunder, whether said payment was required to be paid to the Licensor or any

<PAGE>
 
                                      -13-

readjustment, liquidation, dissolution or a relief for itself under any present
or future Federal, State or other statute, law or regulation for the relief of
debtors, or shall seek or consent acquiesce in the appointment of any trustee,
receiver or liquidator of the Licensee or of all or any substantial part of its
properties, or shall admit in writing its inability to pay its debts generally

SECTION 8.2  LICENSOR'S REMEDIES UPON EVENT OF DEFAULT.  Upon the occurrence of
any of the Events of Default set forth in Section 8.1 or elsewhere, in this
Agreement which default continues for a period of five (5) days after written
notice from Licensor specifying the nature of such default, Licensor may
exercise any or all of the following:

(b)  require that Licensee give additional security for Licensee's performance
of its obligations;

(g)  apply monies from Licensee's show account to satisfy or reduce debt;

(h)  for late payment of one contract, cancel any or all subsequent contracts at
Licensor's option.

Licensee waives any right it may have as to notice or hearing prior to the
exercise of the powers set forth above.  The rights and remedies of Licensee
shall be cumulative, and none shall exclude other rights or remedies allowed by
law or at equity, or set forth in other sections of this Agreement.

SECTION 8.3  REMEDYING DEFAULTS.  The Licensor may, but shall not be required
to, pay such sums or to do any act which requires the expenditure monies or
services which may be necessary or appropriate by reason of the failure or
neglect for the Licensee to perform any of the provisions of this License.  In
the event of the exercise of such right by the Licensor, the Licensee agrees to
pay to the Licensor forthwith upon demand all such sums expended by the Licensor
(or the fair value thereof, whichever is greater), together with interest
thereon at the rate of eighteen (18%) percent per annum, as an Additional
Charge.

SECTION 8.4  TERMINATION WITHOUT DEFAULT.  In the event that the Authorized Area
or the Facilities of which it is a part or any portion thereof, are destroyed or
damaged by fire or other casualty so that in the reasonable judgment of the

with, or in the event of a taking of all or a 
<PAGE>
 
                                      -14-

portion of the Facilities by eminent domain, condemnation or foreclosure, then
the Licensor may terminate this Agreement upon giving to the Licensee notice of
termination not more than ninety (90) days following the event of destruction,
damages or taking and this Agreement shall terminate on the date set forth in
such notice of termination, all with the same force and effect as though the
License Period of this Agreement had originally been scheduled to expire on such
date, and Licensor shall return to the Licensee all monies theretofore paid by
the Licensee to the Licensor as a Security Deposit, Reservation Fee, Basic Fee
or Additional Fee (to the extent not applied by Licensor in accordance with the
terms hereof).

SECTION 8.5  RIGHT TO RE-ENTER.  If this License shall have been terminated as
provided in this Article, or if any execution or attachment shall be issued
against the Licensee or its Property whereupon the Authorized Area shall be
taken or occupied by someone other than the Licensee, then the Licensor may,
without notice, re-enter the Authorized Area, without being liable for any
prosecution thereof, and remove the Licensee and all other persons and any and
all property from the same, as if this License was not in effect.

SECTION 8.6  LIQUIDATED DAMAGES.  If the Licensee cancels the Event covered by
this License, the Licensee agrees to pay to the Licensor, as liquidated damages
and not as a penalty an amount equal to the Reservation Fee and the remainder of
the Basic Fee, as set forth in Article I.  The parties hereto agree that such
amounts constitute reasonable provision for liquidated damages and acknowledge
that the amount of actual damages will be difficult to establish except as
provided in Sections 2.1, 4.2, and 8.11.

In any event, and in addition to the foregoing, the Licensee also agrees to pay
any monies due for Additional Fees and Additional Charges.  The foregoing shall
not constitute Licensor's sole remedy for such cancellation and shall be in
addition to such other legal and equitable rights and remedies as may be
available to Licensor.

SECTION 8.7  LIENS.  To secure the Licensee's obligation hereunder, Licensee
hereby grants the Licensor the first right of lien against all ticket office
receipts and Property of the Licensee hereunder.  The Licensor is empowered to
withhold from ticket office receipts such amount as is outstanding and owed by
the Licensee hereunder.  If the total ticket office receipts are insufficient to
cover such unpaid amounts the Licensor shall have the right to impound the
Licensee's Property at the Facilities, or elsewhere, at the Licensee's expense.
If such unpaid amounts remain unpaid for a period of ten (10) days after the
termination of this License, the Licensor shall have the right to sell the
impounded Property at public auction and to apply the cash proceeds from the
auction less its costs, including attorneys' fees, to the retirement of said
unpaid amounts.

SECTION 8.8  ACTIONS.  Any action by one party to this License against another
arising hereunder shall be maintained in the State of Nevada,; and the Licensee
hereunder consents to same and to the maintenance of such action by the Licensor
against it in said State of Nevada.

SECTION 8.9   CUMULATIVE REMEDIES.  All rights, powers and privileges contained
hereunder upon the Licensor shall be cumulative and shall not be restricted to
those given by law.

SECTION 8.10  FORCE MAJEURE.  In the event that the Licensor's obligations to
the Licensee under this Agreement be delayed, prevented or rendered impractical
by any of the following events:  fire, flood, riot, earthquake, civil commotion,
strike, lockout, labor disturbances, explosion, sabotage, accident, war, other
casualty, Act of God, or any law, ordinance, rule or regulation which becomes
effective after the date of this License or any other cause beyond Licensor's
reasonable control the Licensor shall not be liable to the Licensee for such
delay or failure to perform.  The Licensee hereby waives any claim for damages
or compensation for such delay or failure to perform, other than a return to it
of any monies paid directly to the Licensor but no other.

SECTION 8.11  SUBORDINATION.  This Agreement and any renewals, extensions or
amendments hereof, and all of Licensee's rights and obligations hereunder or
thereunder now or hereafter existing, are unconditionally subject, inferior and
subordinate in priority to any mortgage, deed of trust or other security
interest or lien encumbering the Facilities (or any portion thereof) from time
to time and to the lien of any renewals, extensions, amendments or refinancings
thereof (each, a "Mortgage") and the rights, powers and privileges of any
beneficiary or trustee thereunder.  Notwithstanding the foregoing at the
election of such holder or beneficiary, exercisable in its sole discretion at
any time, its Mortgage shall be subject, inferior and subordinate to the
Agreement.  If such holder or beneficiary shall make such election, and if the
holder of such Mortgage shall exercise any remedies under or in connection with
such Mortgage (or in lieu thereof) after a default by Licensor under such
Mortgage then, at the option of any owner of the Facilities (or the applicable
portion thereof) (after giving effect to such exercise) the Licensee shall
recognize such new owner and this Agreement shall remain in full force and
effect as between such new owner, as Licensor, and Licensee, as licensee.

SECTION 8.12  LICENSE AND NOT A LEASE.  Notwithstanding anything to the contrary
contained herein, this Agreement is a license and not a lease and this Agreement
shall be construed to be a license and not a lease.

SECTION 8.13  DEFAULT BY LICENSOR.  If the Licensor fails or refuses to make the
Facilities and/or the Authorized Areas available to the Licensee on the dates
set forth in this Agreement for any reason other than those specifies in
Sections 8.4 and 8.10 above, then, in addition to any claims, rights or remedies
the Licensee may have, the Licensor shall return to the Licensee all monies paid
to the Licensor along with interest on those monies at the rate of eighteen
percent (18%) per annum from the date the monies were remitted to the Licensor.

Agreement and the Rules and Regulations, the provisions of for this Agreement
shall control.

SECTION 9.4  WAIVER.  The failure of either party hereto at any time or times to
require performance of any provisions hereof shall in no manner effect its right
at a later time to enforce the same provision.  Any waiver by any party or the
breach of any provision contained in this Agreement in any one or more instances
shall not be deemed to be a waiver of any other breach of the same provision or
any other provision contained herein.

SECTION 9.5  NOTICES.  Any notices or other communications required or permitted
hereunder shall be sufficiently given if delivered by a customary overnight
delivery service, or if sent by certified or registered mail, postage prepaid,

(whether it be that of the Licensor or the Licensee or a third person) caused
by, growing out of, or happening in connection with or with respect to the use
by the Licensee, or of any other person or legal entity with the permission
(express or implied) of the Licensee, of the Facilities or its equipment. Such
indemnification by the Licensee shall apply unless such damage or injury results
from the sole negligence, gross negligence or willful misconduct of the Licensor
or any person contracted or hired by Licensor to perform Exclusive Contractual
Services.

(b)  Without limiting the foregoing, the Licensee assumes all costs and expenses
arising from the use of, broadcast, performance or publication, including
musical or other audio or visual presentation, of patented, trademarked, or
copyrighted materials, equipment, devices, processes, or dramatic rights used
during or incorporated in the conduct of its operation hereunder; and the
Licensee agrees to indemnify and hold harmless the Indemnities from all damages,
costs and expenses at law or for equitable relief for or on account of any
patented, trademarked or copyrighted materials, equipment, devices, processes or
dramatic rights furnished to or used by the Licensee or its exhibitors, or any
infringement with respect thereto in connection with this License, including the
costs and expenses of defending any such action, even if it be groundless or
fraudulent.

(c)  Without limiting the foregoing, the Licensee shall also indemnify and save
harmless the Indemnities from all claims, demands, liabilities, damages, costs,
losses and expenses made against or incurred by any of the Indemnities arising
out of injury or loss to third parties caused by Licensee's failure to return
the Authorized Area to the Licensor, vacate the Facilities, relinquish the
Licensor's or Authorized Contractor's equipment at the end of the License
Period, or Licensee's breach of any contract or agreement with a third party to
provide contractual or other services.

SECTION 6.3  WAIVER OF SUBROGATION.  The Licensee hereby waives any and every
claim which arises in its favor and against the Licensor, or against any of the
Additional Indemnities set forth in Article I, for any and all loss or damage
covered by valid and collectible insurance policies to the extent of the
insurance proceeds paid with respect thereto.  Such waiver shall be in addition
to, and not, derogation of, any other waiver or release contained in this
License with respect to any loss or damage to property of the Licensees.
Inasmuch as the waiver will preclude the assignment of any aforesaid claim by
way of subrogation (or otherwise) to an insurance company (or any other person),
the Licensee shall notify its insurers of such waiver.


         ARTICLE VII - LICENSEE'S OBLIGATION AT END OF LICENSE PERIOD
<PAGE>
 
                                      -11-

SECTION 7.1  RETURN OF AUTHORIZED AREA.  At the end of the License Period, the
Licensee shall vacate the Facilities and return the Authorized Area and the
Licensor's equipment to the Licensor, all in the same broom clean condition and
repair as originally furnished to the Licensee, normal wear and tear excepted.
At such time, the Licensee shall remove completely from the Facilities all
goods, wares, merchandise and property of any and all kinds and description
placed therein (herein "Property").

SECTION 7.2 REPAIR OF AUTHORIZED AREA.  The Licensee agrees that if the
Authorized Area, Lobbies, Hallways, Restrooms or other Public Space, or any
other part of the Facilities, shall be damaged by the act, default or negligence
of the Licensee, or of the Licensee's agents, employees, patrons, guests or
invitees, the Licensee will pay to the Licensor upon demand such sum as shall be
necessary to restore said areas to their condition immediately prior to the
commencement of the License Period.  The Licensee hereby assumes full
responsibility for the character, acts and conduct of all persons acting for or
on behalf of said Licensee.

SECTION 7.3  FAILURE TO RETURN THE AUTHORIZED AREA OR VACATE THE FACILITIES.  In
the event the Licensee shall fail to return the Authorized Area to the Licensor
or to vacate the Facilities in accordance with the provisions of Section 7.1,
the Licensor is authorized, at the Licensee's expense, to remove therefrom and
to store or return to the Licensee or, except where the Licensee's failure to do
so is caused by an event beyond the Licensee's control, such as a strike beyond
its control, a national emergency or an Act of God, to treat the same as
abandoned and discarded property and accordingly dispose of the Property.  The
Licensor shall not be liable for any damages or loss to the Property which may
be sustained either in the courts of such removal or in the course of storage,
or in the course of transit, or by virtue of the Licensor's disposal of the
Property and the Licensor is hereby expressly released from any and all such
claims for damages of whatsoever kind or nature.  The Licensor shall be under no
duty, however, to so remove, store or return the Property.

SECTION 7.4  EXTENDED USE CHARGE.  The Licensee shall pay an Extended Use Charge
equal to twice the per diem Basic Fee applicable to Show Days for each day or
portion of a day after the end of the License Period that the Licensee has
failed to return all or any part of the Authorized Area to the Licensor and
vacate the Facilities in accordance with the provisions of Section 7.1, unless
said failure is caused by any of the following events, to the extent such event
is beyond the Licensee's reasonable control: fire, flood, riot, earthquake,
civil commotion, or Act of God.  The liability to pay an Extended Use Charge
does not in any way extend the License Period; is not liquidated damages, is
intended as a penalty against the Licensee for use of the Facilities or the
Authorized Area beyond the License Period; and does not preclude the Licensor
from asserting any other rights against the Licensee, including, but not limited
to, those set forth in Section 7.3 and Article VIII.  The Extended Use Charge is
due and payable at the end of each day for which the Charge is assessed.

SECTION 7.5  FAILURE TO COMPLY LIST.  Licensor and Licensee shall conduct a walk
through of the Authorized Area within twenty-four (24) hours of the end of the
License Period for the purpose of preliminary identifying any failure of the
Licensee to comply with the provisions of Section 7.1.  In addition, Licensor
shall provide to Licensee a final, comprehensive and complete list of 
<PAGE>
 
                                      -12-

Licensee's failure(s) to comply with the provisions of Section 7.1 no later than
the earlier of the following: (i) seven (7) days after the end of the applicable
License Period or (ii) the commencement of any use of the hall or any portion of
the Authorized Area by any person other than the Licensee. The Licensee shall
not be responsible for any alleged non-compliance with Section 7.1 not specially
identified in the list.

                      ARTICLE VIII - DEFAULT AND REMEDIES

SECTION 8.1  EVENTS OF DEFAULT.  The occurrence of any of the following shall be
considered an "Event of Default":

(a) The Licensee shall fail to pay in full and when due any payment required
hereunder, whether said payment was required to be paid to the Licensor or any
Authorized Contractor;

(b) The Licensee shall fail to pay promptly any sales, use, excise or other
taxes when due or fail, upon request of the Licensor, to provide evidence of
same to Licensor;

(c) The Licensee shall fail to obtain or pay for any and all necessary permits
and licenses, including union or trade organization clearances, and Fire
Marshall approvals, when and where required, or fail, upon the Licensor's
request, to provide evidence of such permits or licenses to the Licensor;

(d) Any other default or breach of any covenant or agreement contained herein
including the specific duty to provide evidence of insurance coverage as
provided in Article VI;

(e) The Licensee shall make an assignment for the benefit of creditors or shall
file a voluntary petition in bankruptcy or shall be adjudicated bankrupt or
insolvent, or shall file any petition or answer seeking any reorganization,
arrangement, composition, readjustment, liquidation, dissolution or similar
relief for itself under any present or future Federal, State or other statute,
law or regulation for the relief of debtors, or shall seek or consent to or
acquiesce in the appointment of any trustee, receiver or liquidator of the
Licensee or of all or any substantial part of its properties, or shall admit in
writing its inability to pay its debts generally as they become due;

(f) A petition shall be filed against the Licensee in bankruptcy or under any
other law seeking any reorganization, arrangement, composition, readjustment,
liquidation, dissolution, or similar relief.

(g) Licensee shall materially diverge from the plan of operation without the
prior written consent of Licensor.

SECTION 8.2  LICENSOR'S REMEDIES UPON EVENT OF DEFAULT.  Upon the occurrence of
any of the Events of Default set forth in Section 8.1 or elsewhere in this
Agreement which default continues for a period of five (5) days after written
notice from Licensor specifying the nature of such default, Licensor may
exercise any or all of the following:
<PAGE>
 
                                      -13-

(a) accelerate payment of the Basic Fee;

(b) require that Licensee give additional security for Licensee's performance of
its obligations;

(c) declare this Agreement terminated and revoke the license given hereby;

(d) enter and take exclusive possession of and remove all persons and property
from the Authorized Areas and the Facility;

(e) assert and enforce claims against any bond provided under this Agreement;

(f) refuse to commence, or discontinue the rendition of all services or
utilities to Licensee and the Authorized Area;

(g) apply monies from Licensee's show account to satisfy or reduce debt;

(h) for late payment of one contract, cancel any or all subsequent contracts at
Licensor's option.

Licensee waives any right it may have as to notice or hearing prior to the
exercise of the powers set forth above.  The rights and remedies of Licensor
shall be cumulative, and none shall exclude other rights or remedies allowed by
law or at equity, or set forth in other sections of this Agreement.

SECTION 8.3  REMEDYING DEFAULTS.  The Licensor may, but shall not be required
to, pay such sums or to do any act which requires the expenditure of monies or
services which may be necessary or appropriate by reason of the failure or
neglect of the Licensee to perform any of the provisions of the License.  In the
event of the exercise of such right by the Licensor, the Licensee agrees to pay
to the Licensor forthwith upon demand all such sums expended by the Licensor (or
the fair value thereof, whichever is greater), together with interest thereon at
the rate of eighteen (18%) percent per annum, as an Additional Charge.

SECTION 8.4  TERMINATION WITHOUT DEFAULT.  In the event that the Authorized Area
or the Facilities of which it is a part or any potion thereof, are destroyed or
damaged by fire or other casualty so that in the reasonable judgment of the
Licensor its or the Licensee's use thereof would be substantially interfered
with, or in the event of a taking of all or a portion of the Facilities by
eminent domain, condemnation or foreclosure, then the Licensor may terminate
this Agreement upon giving to the Licensee notice of termination not more than
ninety (90) days following the event of destruction, damage or taking and this
Agreement shall terminate on the date set forth in such notice of termination,
all with the same force and effect as though the License Period of this
Agreement had originally been scheduled to expire on such date, and Licensor
shall return to the Licensee all monies theretofore paid the Licensee to the
Licensor as a Security Deposit, Reservation Fee, Basic Fee or Additional Fee (to
the extent not applied by Licensor in accordance with the term hereof).

SECTION 8.5  RIGHT TO RE-ENTER.  If this License shall have been terminated as
provided in this Article, or if any execution or attachment shall be issued
against the Licensee or its Property 
<PAGE>
 
                                      -14-

whereupon the Authorized Area shall be taken or occupied by someone other than
the Licensee, then the Licensor may, without notice, re-enter the Authorized
Area, without being liable for any prosecution thereof, and remove the Licensee
and all other persons and any and all property from the same, as if this License
was not in effect.

SECTION 8.6   LIQUIDATED DAMAGES.  If the Licensee cancels the Event covered by
this License, the Licensee agrees to pay to the Licensor, as liquidated damages
and not as a penalty an amount equal to the Reservation Fee and the remainder of
the Basic Fee, as set forth in Article I. The parties hereto agree that such
amounts constitute reasonable provision for liquidated damages and acknowledge
that the amount of actual damages will be difficult to establish except as
provided in Section 2.1, 4.2, and 8.11.

In any event, and in addition to the foregoing, the Licensee also agrees to pay
any monies due for Additional Fees and Additional Charges.  The foregoing shall
not constitute Licensor's sole remedy for such cancellation and shall be in
addition to such other legal and equitable rights and remedies as may be
available to Licensor.

SECTION 8.7   LIENS.  To secure the Licensee's obligation hereunder, Licensee
hereby grants the Licensor the right of lien against all ticket office receipts
and Property of Licensee hereunder.  The Licensor is empowered to withhold from
ticket office receipts such amount as is outstanding and owed by the Licensee
hereunder.  If the total ticket office receipts are insufficient to cover such
unpaid amounts the Licensor shall have the right to impound the Licensee's
Property at the Facilities, or elsewhere, at the Licensee's expense.  If such
unpaid amounts remain unpaid for a period of ten (10) days after the termination
of this License, the Licensor shall have the right to sell the impounded
Property at public auction and to apply the cash proceeds from the auction less
its costs, including attorneys' fees, to the retirement of said unpaid amounts.

SECTION 8.8   ACTIONS.  Any action by one party to this License against another
arising hereunder shall be maintained in the State of Nevada; and the Licensee
hereunder consents to same and to the maintenance of such action by the Licensor
against it in said State of Nevada.

SECTION 8.9   CUMULATIVE REMEDIES.  All rights, powers and privileges contained
hereunder upon the Licensor shall be cumulative and shall not be restricted to
those given by law.

SECTION 8.10  FORCE MAJEURE.  In the event that the Licensor's obligations to
the Licensee under this Agreement be delayed, prevented or rendered impractical
by any of the following events: fire, flood, riot, earthquake, civil commotion,
strike, lockout, labor disturbances, explosion, sabotage, accident, war, other
casualty, Act of God, or any law, ordinance, rule or regulation which becomes
effective after the date of this License or any other cause beyond Licensor's
reasonable control the Licensor shall not be liable to the Licensee for such
delay or failure to perform.  The Licensee hereby waives any claim for damages
or compensation for such delay or failure to perform, other than a return to it
of any monies paid directly to the Licensor, but no other.

SECTION 8.11  SUBORDINATION.  This Agreement and any renewals, extensions or
amendments hereof, and all of Licensee's rights and obligations hereunder or
thereunder now or hereafter 
<PAGE>
 
                                      -15-

existing, are unconditionally subject, inferior and subordinate in priority to
any mortgage, deed of trust or other security interest or lien encumbering the
Facilities (or any portion thereof) from time to time and to the lien of any
renewals, extensions, amendments or refinancings thereof (each, a "Mortgage")
and the rights, powers and privileges of any beneficiary or trustee thereunder.
Notwithstanding the foregoing, at the election of such holder or beneficiary,
exercisable in its sole discretion at any time, its Mortgage shall be subject,
inferior and subordinate to this Agreement. If such holder or beneficiary, shall
made such election, and if the holder of such Mortgage shall exercise any
remedies under or in connection with such Mortgage (or in lieu thereof) after a
default by Licensor under such Mortgage then, at the option of any owner of the
Facilities (or the applicable portion thereof) (after giving effect to such
exercise) the Licensee shall recognize such new owner and this Agreement shall
remain in full force and effect as between such new owner, as Licensor, and
Licensee, as licensee.

SECTION 8.12  LICENSE AND NOT A LEASE.  Notwithstanding anything to the contrary
contained herein, this Agreement is a license and not a lease and this Agreement
shall be construed to be a license and not a lease.

SECTION 8.13  DEFAULT BY LICENSOR.  If the Licensor fails or refuses to make the
Facilities and/or the Authorized Areas available to the Licensee on the dates
set forth in this Agreement for any reason other than those specifies in Section
8.4 and 8.10 above, then, in addition to any claims, rights or remedies the
Licensee may have, the Licensor shall return to the Licensee all monies paid to
the Licensor along with interest on those monies at the rate of eighteen percent
(18%) per annum from the date the monies were remitted to the Licensor.

                     ARTICLE IX - MISCELLANEOUS PROVISIONS

SECTION 9.1  NON-DISCRIMINATION.  The Licensee shall not discriminate against
any person or persons in connection with admission, services or privilege

wishes to use copyrighted music or other copyrighted material it will be
necessary for Licensee to make arrangements with the appropriate owners of such
material or agents of such owners for a license to use or perform such
copyrighted music or material or to otherwise qualify for an exemption.  The
Sands Expo and Convention Center retains the right to regulate the volume of any
sound, whether it be music, voice, special or artificial effects to the extent
that the same interferes with other licensees within the facilities or is
determined to be offensive or otherwise violates the rules and regulations or
License Agreement.

Regulations have been

The Licensor reserves the right to change such Rules and Regulations in writing
from time to time and will provide the Licensee with such changed Rules and
Regulations which shall be binding upon the Licensee. If there is at any time a
conflict between the provisions of this Agreement and the Rules and Regulations,
the provisions of this Agreement shall control.

SECTION 9.4   WAIVER. The failure of either party hereto at any time or times to
require performance of any provisions hereof shall in no manner affect its right
at a later time to enforce the same provision. Any waiver by any party or the
breach of any provision contained in this Agreement in any one or more instances
shall not be deemed to be a waiver of any other breach of the same provision or
any other provision contained herein.

SECTION 9.5   NOTICES. Any notices or other communications required or permitted
hereunder shall be sufficiently given if delivered by a customary overnight
delivery service, or if sent by certified or registered mail, postage prepaid,

for each in Article I of this Agreement or to such other address as any party
shall have provided to the other parties from time to time in accordance with
the provisions of this Section 9.5.

whatsoever. This Agreement may be changed or amended only by a written
instrument duly signed by all of the parties hereto. This agreement must be
signed by Licensee and returned within thirty (30) days from the date of

SECTION 2.2    PROHIBITED USES.  The Licensee shall not use or allow the

                                      -5-

additions to the plan of operation as the Licensor may reasonably deem necessary
or desirable for the purpose of insuring the safe and orderly operation of the

after such notice shall constitute an Event of Default, as set forth in Article

or invitees shall be rendered to and paid directly by the exhibitor or invitee.
Licensor shall be under no obligation to provide a Contractual Service it has

All required insurance policies shall provide that (i) the insurance carrier
will give written notice to Licensor at least thirty (30) days prior to any

those named Additional Indemnities set forth in Article I (herein "Indemnities")
of and from any and all claims, demands, liabilities, damages, costs, losses and
expenses (including attorneys' fees and disbursements) for any injury to,
including death (whether they be third persons or employees of either the
Licensor or the Licensee) and any loss (through theft or otherwise) of or damage
to property (whether it be that of the Licensor or the Licensee or a third
person) caused by, growing out of, or happening in connection with or with
respect to the use by the Licensee, or of any other person or legal entity with
the permission (express or implied) of the Licensee, of the Facilities or its
equipment. Such indemnification by the Licensee shall apply unless such damage
or injury results from the sole negligence, gross negligence or willful
misconduct of the Licensor or any person contracted or hired by Licensor to
perform Exclusive Contractual Services.

     (b)  Without limiting the foregoing, the Licensee assumes all costs and
expenses arising from the use of, broadcast, performance or publication,

Indemnities from all damages, costs and expenses at law or for equitable relief

connection with this License, including the costs and expenses of defending any
such action, even if it be groundless or fraudulent.

     (c)  Without limiting the foregoing, the Licensee shall also indemnify and
save harmless the Indemnities from all claims, demands, liabilities, damages,
costs, losses and expenses made against or incurred by any of the Indemnities
arising out of injury or loss to third parties caused by Licensee's failure to
return the Authorized Area to the Licensor, vacate the Facilities, relinquish
the Licensor's or Authorized Contractor's equipment at the end of the License
Period, or Licensee's breach of any contract or agreement with a third party to
provide contractual or other services.

SECTION 6.3    WAIVER OF SUBROGATION.  The Licensee hereby waives any and every
claim which arises in its favor and against the Licensor, or against any of the
Additional Indemnities set forth in Article I, for any and all loss or damage
covered by valid and collectible insurance policies to the extent of the
insurance proceeds paid with respect thereto. Such waiver shall be in addition
to, and not, derogation of, any other waiver or release contained in this
License with respect to any loss or damage to property of the Licensees.
Inasmuch as the waiver will preclude the assignment of any aforesaid claim by
way of subrogation (or otherwise) to an insurance company (or any other person),
the Licensee shall notify its insurers of such waiver.

Licensor or to vacate the Facilities in accordance with the provisions of
Section 7.1, the Licensor is authorized, at the Licensee's expense, to remove
therefrom and to store or return to the Licensee or, except where the Licensee's
failure to do so is caused by an event beyond the Licensee's control, such as a
strike beyond its control, a national emergency or an Act of God, to treat the
same as abandoned and discarded property and accordingly dispose of the
Property. The Licensor shall not be liable for any damages or loss to the
Property which may be sustained either in the course of such removal or in the
course of storage, or in the course of transit, or by virtue of the Licensor's
disposal of the Property and the Licensor is hereby expressly released from any
and all such claims for damages of whatsoever kind or nature. The Licensor shall
be under no duty, however, to so remove, store or return the Property.

SECTION 7.4    EXTENDED USE CHARGE.  The Licensee shall pay an Extended Use
Charge equal to twice the per diem Basic Fee applicable to Show Days for each
day or portion of a day after the end of the License Period that the Licensee
has failed to return all or any part of the Authorized Area to the Licensor and
vacate the Facilities in accordance with the provisions of Section 7.1, unless
said failure is caused by any of the following events, to the extent that such
event is beyond the Licensee's reasonable control: fire, flood, riot,
earthquake, civil commotion, or Act or God. The liability to pay an Extended Use
Charge does not in any way extend the License Period; is not liquidated damages;
is intended as a penalty against the Licensee for use of the Facilities or the
Authorized Area beyond the License Period; and does not preclude the Licensor
from asserting any other rights against the Licensee, including, but not limited
to, those set forth in Section 7.3 and Article VIII. The Extended Use Charge is
due and payable at the end of each day for which the Charge is assessed.

SECTION 7.5    FAILURE TO COMPLY LIST.  Licensor and Licensee shall conduct a
walk through of the Authorized Area within twenty-four (24) hours of the end of
the License Period for the purpose of preliminary identifying any failure of the
Licensee to comply with the provisions of Section 7.1. In addition, Licensor
shall provide to Licensee a final, comprehensive and complete list of Licensee's
failure(s) to comply with the provisions of Section 7.1 no later than the
earlier of the following: (i) seven (7) days after the end of the applicable
License Period or (ii) the commencement of any use of the hall or any portion of
the Authorized Area by any person other than the Licensee. The Licensee shall
not be responsible for any alleged non-compliance with Section 7.1 not
specifically identified in the list.

                      ARTICLE VIII - DEFAULT AND REMEDIES

SECTION 8.1    EVENTS OF DEFAULT.  The occurrence of any of the following shall
be considered an "Event of Default":

(a)  The Licensee shall fail to pay in full and when due any payment required
     hereunder, whether said payment was required to be paid to the Licensor or
     any Authorized Contractor;

(b)  The Licensee shall fail to pay promptly any sales, use, excise or other
     taxes when due or fail, upon request of the Licensor, to provide evidence
     of same to the Licensor;

(c)  The Licensee shall fail to obtain or pay for any and all necessary permits
     and licenses, including union or trade organization clearances, and Fire
     Marshal approvals, when and where required, or fail, upon the Licensor's
     request, to provide evidence of such permits or licenses to the Licensor;

(d)  Any other default or breach of any covenant or agreement contained herein
     including the specific duty to provide evidence of insurance coverage as
     provided in Article VI.

(e)  The Licensee shall make an assignment for the benefit of creditors or shall
     file a voluntary petition in bankruptcy or shall be adjudicated bankrupt or
     insolvent, or shall file any petition or answer seeking any reorganization,
     arrangement, composition, readjustment, liquidation, dissolution or similar
     relief for itself under any present or future Federal, state or other
     statue, law or regulation for the relief of debtors, or shall seek or
     consent to or acquiesce in the appointment of any trustee, receiver or
     liquidator of the Licensee or of all or any substantial part of its
     properties, or shall admit in writing its inability to pay its debts
     generally as they become due;

(f)  A petition shall be filed against the Licensee in bankruptcy or under any
     other law seeking any reorganization, arrangement, composition,
     readjustment, liquidation, dissolution, or similar relief.

(g)  Licensee shall materially diverge from the plan of operation without the
     prior written consent of Licensor.

SECTION 8.2    LICENSOR'S REMEDIES UPON EVENT OF DEFAULT.  Upon the occurrence
of any of the Events of Default set forth in Section 8.1 or elsewhere in this
Agreement which default continues for a period of five (5) days after written
notice from Licensor specifying the nature of such default, Licensor may
exercise any or all of the following:

(a)  accelerate payment of the Basic Fee;

(b)  require that Licensee give additional security for Licensee's performance
     of its obligations;

<PAGE>
 
                                     -13-

(d)  enter and take exclusive possession of and remove all persons and property
     from the Authorized Areas and the Facility;

(e)  assert and enforce claims against any bond provided under this Agreement;

(f)  refuse to commence, or discontinue the rendition of all services or
     utilities to Licensee and the Authorized Area;

(g)  apply monies from Licensee's show account to satisfy or reduce debt;

(h)  for late payment of one contract, cancel any or all subsequent contracts at
     Licensor's option.

Licensee waives any right it may have as to notice or hearing prior to the
exercise of the powers set forth above. The rights and remedies of Licensor
shall be cumulative, and no one shall exclude other rights or remedies allowed
by law or at equity, or set forth in other sections of this Agreement.

SECTION 8.3    REMEDYING DEFAULTS.  The Licensor may, but shall not be required
to, pay such sums or to do any act which requires the expenditure of monies or
services which may be necessary or appropriate by reason of the failure or
neglect of the Licensee to perform any of the provisions of this License. In the
event of the exercise of such right by the Licensor, the Licensee agrees to pay
to the Licensor forthwith upon demand all such sums expended by the Licensor (or
the fair value thereof, whichever is greater), together with interest thereon at
the rate of eighteen (18%) percent per annum, as an Additional Charge.

SECTION 8.4    TERMINATION WITHOUT DEFAULT.  In the event that the Authorized
Area or the Facilities of which it is a part or any portion thereof, are
destroyed or damaged by fire or other casualty so that in the reasonable
judgment of the Licensor its or the Licensee's use thereof would be
substantially interfered with, or in the event of a taking of all or a portion
of the Facilities by eminent domain, condemnation or foreclosure, then the
Licensor may terminate this Agreement upon giving to the Licensee notice of
termination not more than ninety (90) days following the event of destruction,
damage or taking and this Agreement shall terminate on the date set forth in
such notice of termination, all with the same force and effect as though the
Licensed Period of this Agreement had originally been scheduled to expire on
such date, and Licensor shall return to the Licensee all monies theretofore paid
by the Licensee to the Licensor as a Security Deposit, Reservation Fee, Basic
Fee or Additional Fee (to the extent not applied by Licensor in accordance with
the terms hereof).

SECTION 8.5    RIGHT TO RE-ENTER.  If this License shall have been terminated as
provided in this Article, or if any execution or attachment shall be issued
against the Licensee or its Property whereupon the Authorized Area shall be
taken or occupied by someone other than the Licensee, then the Licensor may,
without notice, re-enter the Authorized Area, without being liable for any
prosecution thereof, and remove the Licensee and all other persons and any and
all property from the same, as if this License was not in effect.

SECTION 8.6    LIQUIDATED DAMAGES.  If the Licensee cancels the Event covered by
this License, the Licensee agrees to pay to the Licensor, as liquidated damages
and not as a penalty an amount equal to the Reservation Fee and the remainder of
the Basic Fee, as set forth in Article 1. The 
<PAGE>
 
                                     -14-

parties hereto agree that such amounts constitute reasonable provision for
liquidated damages and acknowledge that the amount of actual damages will be
difficult to establish except as provided in Sections 2.1, 4.2, and 8.11.

In any event, and in addition to the foregoing, the Licensee also agrees to pay
any monies due for Additional Fees and Additional Charges. The foregoing shall
not constitute Licensor's sole remedy for such cancellation and shall be in
addition to such other legal and equitable rights and remedies as may be
available to Licensor.

SECTION 8.7    LIENS.  To secure the Licensee's obligation hereunder, Licensee
hereby grants the Licensor the first right of lien against all ticket office
receipts and Property of the Licensee hereunder. The Licensor is empowered to
withhold from ticket office receipts such amount as is outstanding and owed by
the Licensee hereunder. If the total ticket office receipts are insufficient to
cover such unpaid amounts the Licensor shall have the right to impound the
Licensee's Property at the Facilities, or elsewhere, at the Licensee's expense.
If such unpaid amounts remain unpaid for a period of ten (10) days after the
termination of this License, the Licensor shall have the right to sell the
impounded Property at public auction and to apply the cash proceeds from the
auction less its costs, including attorneys' fees, to the retirement of said
unpaid amounts.

SECTION 8.8    ACTIONS.  Any action by one party to this License against another
arising hereunder shall be maintained in the State of Nevada; and the Licensee
hereunder consents to same and to the maintenance of such action by the Licensor
against it in said State of Nevada.

SECTION 8.9    CUMULATIVE REMEDIES.  All rights, powers and privileges contained
hereunder upon the Licensor shall be cumulative and shall not be restricted to
those given by law.

SECTION 8.10   FORCE MAJEURE.  In the event that the Licensor's obligations to
the Licensee under this Agreement be delayed, prevented or rendered impractical
by any of the following events: fire, flood, riot, earthquake, civil commotion,
strike, lockout, labor disturbances, explosion, sabotage, accident, war, other
casualty, Act of God, or any law, ordinance, rule or regulation which becomes
effective after the date of this License or any other cause beyond Licensor's
reasonable control the Licensor shall not be liable to the Licensee for such
delay or failure to perform. The Licensee hereby waives any claim for damages or
compensation for such delay or failure to perform, other than a return to it of
any monies paid directly to the Licensor, but no other.

SECTION 8.11   SUBORDINATION.  This Agreement and any renewals, extensions or
amendments hereof, and all of Licensee's rights and obligations hereunder or
thereunder now or hereafter existing, are unconditionally subject, inferior and
subordinate in priority to any mortgage, deed of trust or other security
interest or lien encumbering the Facilities (or any portion thereof) from time
to time and to the lien of any renewals, extensions, amendments or refinancings
thereof (each, a "Mortgage") and the rights, powers and privileges of any
beneficiary or trustee thereunder. Notwithstanding the foregoing, at the
election of such holder or beneficiary, exercisable in its sole discretion at
any time, its Mortgage shall be subject, inferior and subordinate to this
Agreement. If such holder or beneficiary shall make such election, and if the
<PAGE>
 
                                     -15-

holder of such Mortgage shall exercise any remedies under or in connection with
such Mortgage (or in lieu thereof) after a default by Licensor under such
Mortgage then, at the option of any owner of the Facilities (or the applicable
portion thereof) (after giving effect to such exercise) the Licensee shall
recognize such new owner and this Agreement shall remain in full force and
effect as between such new owner, as Licensor, and Licensee, as licensee.

SECTION 8.12   LICENSE AND NOT A LEASE.  Notwithstanding anything to the
contrary contained herein, this Agreement is a license and not a lease and this
Agreement shall be construed to be a license and not a lease.

SECTION 8.13   DEFAULT BY LICENSOR.  If the Licensor fails or refuses to make
the Facilities and/or the Authorized Areas available to the Licensee on the
dates set forth in this Agreement for any reason other than those specified in
Sections 8.4 and 8.10 above, then, in addition to any claims, rights or remedies
the Licensee may have, the Licensor shall return to the Licensee all monies paid
to the Licensor along with interest on those monies at the rate of eighteen
percent (18%) per annum from the date the monies were remitted to the Licensor.

                     ARTICLE IX - MISCELLANEOUS PROVISIONS

SECTION 9.1    NON-DISCRIMINATION.  The Licensee shall not discriminate against
any person or persons in connection with admission, services or privileges
offered to or enjoyed by the general public because of race, creed, ancestry,
sexual orientation, disability, color, sex, marital status, age, religion or
national origin.

SECTION 9.2    AUDIO/VISUAL PRESENTATIONS.  The Sands Expo and Convention Center
does not regulate, control, approve or disapprove any broadcast, performance or
publication of music or any other audio or visual presentations. The Sands Expo
and Convention Center does not play or perform any music, nor does it offer
referrals or contracts with anyone who does. If the Licensee, or an exhibitor,
wishes to use copyrighted music or other copyrighted material it will be
necessary for Licensee to make arrangements with the appropriate owners of such
material or agents of such owners for a license to use or perform such
copyrighted music or material or to otherwise qualify for an exemption. The
Sands Expo and Convention Center retains the right to regulate the volume of any
sound, whether it be music, voice, special or artificial effects to the extent
that the same interferes with other licensees within the facilities or is
determined to be offensive or otherwise violates the rules and regulations or
License Agreement.

SECTION 9.3    RULES AND REGULATIONS.  The Licensor's Rules and Regulations are
hereby incorporated into this Agreement by reference. Copies of such Rules and
Regulations have been provided to the Licensee and the Licensee hereby
acknowledges receipt thereof. The Licensor reserves the right to change such
Rules and Regulations in writing from time to time and will provide the Licensee
with such changed Rules and Regulations which shall be binding upon the
Licensees. If there is at any time a conflict between the provisions of this
Agreement and the Rules and Regulations, the provisions of this Agreement shall
control.

SECTION 9.4    WAIVER.  The failure of either party hereto at any time or times
to require performance of any provisions hereof shall in no manner affect its
right at a later time to enforce 
<PAGE>
 
                                     -16-

the same provision. Any waiver by any party or the breach of any provision
contained in this Agreement in any one or more instances shall not be deemed to
be a waiver of any other breach of the same provision or any other provision
contained herein.

SECTION 9.5    NOTICES.  Any notices or other communications required or
permitted hereunder shall be sufficiently given if delivered by a customary
overnight delivery service, or if sent by certified or registered mail, postage
prepaid, to the Licensor or the Licensee, as the case may be, at the address as
set forth for each in Article 1 of this Agreement or to such other address as
any party shall have provided to the other parties from time to time in
accordance with the provisions of this Section 9.5.

SECTION 9.6    ENTIRE AGREEMENT.  This Agreement constitutes the entire
agreement between the parties hereto with respect to the subject matter hereto
and supersedes all proposals, negotiations and understandings of any nature
whatsoever. This Agreement may be changed or amended only by a written
instrument duly signed by all of the parties hereto. This agreement must be
signed by Licensee and returned within thirty (30) days from the date of
Agreement set forth in Article 1. If not so returned to Licensor this Agreement
shall, at Licensor's option be rendered null and void. In any event, this
Agreement shall not be enforceable until signed by Licensor.

SECTION 9.7    BINDING EFFECT, ASSIGNABILITY.  This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective heirs,
legal representatives, successors and assigns. This Agreement or any rights
hereunder may not be assigned by the Licensee without the express written
consent of Licensor, which consent will not be unreasonably withheld.

SECTION 9.8    CAPTIONS.  The captions of the several provisions of this
Agreement have been inserted for convenience only and do not constitute a part
of this Agreement.

SECTION 9.9    GOVERNING LAW.  This Agreement shall be governed and construed in
accordance with the laws of the State of Nevada applicable to contracts made and
to be performed wholly within such state.

SECTION 9.10   COUNTERPARTS.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

SECTION 9.11   SIGNATURES.  If you are in agreement with the contents of this
contract, please sign on the space indicated and return by OCTOBER 1, 1997.  If
                                                           ---------------

days prior to your major arrival day of SUNDAY, AUGUST 20, 1998. After that
date, the hotel will continue to hold any rooms in your block not assigned to a
specific attendee of your group if you pay for them in full at that time.
Advance payments will be refunded by the hotel after your convention dates if
rooms you paid for in advance were later paid for by your attendees. If you
prefer, after consultation with you, the hotel will offer unassigned rooms in
your block to other individuals or groups in an effort to reduce damages you may
be required to pay pursuant to the Performance Clause as outlined in this
agreement. Members of your group may still request rooms after the cut off date
of JULY 30, 1998. Such rooms will be available at the hotel's prevailing rate.

                                 RESERVATIONS

We understand that reservations for your meeting will be made by rooming list.
The LAS VEGAS HILTON will make reasonable efforts to ensure that reservations
for your meeting are not accepted from individuals who are not identified on the
list.  MAGIC INTERNATIONAL agrees to provide the rooming list to the LAS VEGAS
HILTON's Sales/Convention Service Department no later than JULY 30 1998.

                              CANCELLATION POLICY

The LAS VEGAS HILTON has agreed to offer the favorable terms presented to MAGIC
INTERNATIONAL based on its expectation that your event will generate revenue to
the LAS VEGAS HILTON from sleeping rooms, function space usage, food and
beverage events and ancillary services such as restaurant outlets, telephone,
movies, room service and other services offered by the hotel at additional cost
to guests. If your event does not take place at this hotel for any reason, LAS
VEGAS HILTON will not only have lost this revenue, but will incur the costs
involved in attempting to find other individuals or groups to replace the lost
business. The closer in time to the date of your event that a cancellation
occurs, the less likely it is that the LAS VEGAS HILTON will be able to replace
any or all of your business.

MAGIC INTERNATIONAL agrees that should it change its meeting site to another
hotel, or cancel this commitment for any reason except as defined below, actual
damages would be difficult to determine. The following schedule represents a
reasonable effort on behalf of the LAS VEGAS HILTON to establish its actual
damages for such cancellation. It is agreed that such schedule shall represent
liquidated damage to be paid by MAGIC INTERNATIONAL for cancellation of this
contract.

Cancellation within one (1) year of convention date:

- -- 60% of anticipated gross revenues (derived from sleeping rooms, food and
beverage functions and ancillary enterprises) if your meeting was held as
scheduled.

In the event that this meeting is canceled prior to the time that specific
sleeping room rates are agreed upon, menu prices are established, or exhibit
space rates are established, then our current room rates, current menu prices
and current exhibit space rates, as set forth herein, will be used in
calculating the hotel's anticipated gross revenues.  Ancillary revenues will be
calculated using the average daily per occupied room ancillary revenue for the
same month as the convention from the most recent year available.

                                 FORCE MAJEURE

Any prevention, delay or stoppage due to strikes, lockouts, labor disputes, Acts
of God, inability to obtain labor or materials or reasonable substitutes
therefor, governmental restrictions, governmental regulations, governmental
controls, enemy or hostile governmental actions, civil commotion, riots, fires,
floods, explosions, quarantine, power shortages, power outages, or other causes
beyond the reasonable control of the party obligated to perform shall excuse the
performance by such party for a period of time equal to such prevention, delay
or stoppage. However, if the length of the prevention, delay or stoppage on the
party of one party as a result of a force majeure is such that continuation of
the contract becomes commercially impractical, the other party may terminate the

                                                                               7

contract upon notice to the party which is unable to perform, and neither party
shall have any further liability to the other party.

                        AMERICANS WITH DISABILITIES ACT

The hotel represents and MAGIC INTERNATIONAL acknowledges that beginning on
January 1, 1992, and continuing thereafter in accordance with the compliance
dates established or required under Title III of the Americans With Disabilities
Act and the regulations promulgated thereunder ("ADA"), the hotel facilities
being rented to MAGIC INTERNATIONAL under this Agreement, its guest rooms,
common areas and its transportation services will be in compliance with the
public accommodation requirements of the ADA.

                                AUXILIARY AIDS

MAGIC INTERNATIONAL agrees that by JUNE 26, 1998, it will furnish to the hotel a
list of any auxiliary aids needed in any meeting room or function space by its
attendees. Should such auxiliary aids be required, MAGIC INTERNATIONAL shall pay
all charges associated with the acquisition, rental or provision of such aids.

When requests for sleeping room assignments are made, please ask your attendees
to notify the hotel of their auxiliary aid needs, so that we may notify you as
to the names of businesses with which you may contract to obtain those aids.

                                 OPTION STATUS

These arrangements are first-come, first serve.  Space is confirmed definitely
only after receipt of the signed and counter-signed agreement.  By signing and
returning this Agreement to the LAS VEGAS HILTON, you will enable the LAS VEGAS
HILTON to establish these arrangements on a definite basis, provided the dates
can be cleared.

harmless the Las Vegas Hilton Corporation, its parents, subsidiaries,

to recover all of its actual damages for breach of these provisions.

                                  ASSIGNMENT

This Agreement may not be assigned by MAGIC INTERNATIONAL without the prior

OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING HOLDER

     The Company will not accept any alternative, conditional or contingent
tenders. Each tendering holder, by execution of a Letter of Transmittal (or
facsimile thereof), waives any right to receive any notice of the acceptance of
such tender.

     2. GUARANTEE OF SIGNATURES. No signature guarantee on this Letter of
Transmittal is required if:

     (i)  this Letter of Transmittal is signed by the registered holder
          (which term, for purposes of this document, shall include any
          participant in DTC whose name appears on the Company's register of
          holders maintained by the Company as the owner of the Original Notes)
          of Original Notes tendered herewith, unless such holder(s) has
          completed either the box entitled "Special Issuance Instructions" or
          the box entitled "Special Delivery Instructions" above, or

     (ii) such Original Notes are tendered for the account of a firm that

All Original Notes represented by Certificates delivered to the Exchange Agent

<PAGE>
 
     Except as otherwise provided herein, tenders of Original Notes may be
withdrawn at any time on or prior to the Expiration Date. In order for a
withdrawal to be effective on or prior to that time, a written, telegraphic,
or facsimile transmission of such notice of withdrawal must be timely
received by the Exchange Agent at one of its addresses set forth above or in the
Prospectus on or prior to the Expiration Date. Any such notice of withdrawal
must specify the name of the person who tendered the Original Notes to be
withdrawn, the aggregate principal amount of Original Notes to be withdrawn, and
(if Certificates for Original Notes have been tendered) the name of the
registered holder of the Original Notes as set forth on the Certificate for the
Original Notes, if different from that of the person who tendered such Original
Notes. If Certificates for the Original Notes have been delivered or otherwise
identified to the Exchange Agent, then prior to the physical release of such
Certificates for the Original Notes, the tendering holder must submit the serial
numbers shown on the particular Certificates for the Original Notes to be
withdrawn and the signature on the notice of withdrawal must be guaranteed by an
Eligible Institution, except in the case of Original Notes tendered for the
account of an Eligible Institution. If Original Notes have been tendered
pursuant to the procedures for book-entry transfer set forth in the Prospectus
under "The Exchange Offer--Procedures for Tendering," the notice of withdrawal
must specify the name and number of the account at DTC to be credited with the
withdrawal of Original Notes, in which case a notice of withdrawal will be
effective if delivered to the Exchange Agent by written, telegraphic, or
facsimile transmission. Withdrawals of tenders of Original Notes may not be
rescinded. Original Notes properly withdrawn will not be deemed validly tendered
for purposes of the Exchange Offer, but may be retendered at any subsequent time
on or prior to the Expiration Date by following any of the procedures described
in the Prospectus under "The Exchange Offer-- Procedures for Tendering."

     All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, in its
sole discretion, whose determination shall be final and binding on all parties.
None of the Company, any of its affiliates or assigns, the Exchange Agent or any
other person shall be under any duty to give any notification of any
irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification. Any Original Notes which have been tendered but
which are withdrawn will be returned to the holder thereof without cost to such
holder promptly after withdrawal.

     5. SIGNATURES ON LETTER OF TRANSMITTAL, ASSIGNMENTS AND ENDORSEMENTS. If
this Letter of Transmittal is signed by the registered holder(s) of the Original
Notes tendered hereby, the signature(s) must correspond exactly with the name(s)
as written on the face of the Certificate(s) without alteration, enlargement or

     If any tendered Original Notes are registered in different name(s) on
several Certificates, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal (or facsimiles thereof) as there are different
registrations of Certificates.

by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing and must submit proper evidence
satisfactory to the Company, in its sole discretion, of each such person's
authority so to act.

     When this Letter of Transmittal is signed by the registered owner(s) of the
Original Notes listed and transmitted hereby, no endorsement(s) of
Certificate(s) or separate bond power(s) are required unless Exchange Notes are
to be issued in the name of a person other than the registered holder(s).
Signature(s) on such Certificate(s) or bond power(s) must be guaranteed by an
Eligible Institution.

     If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Original Notes listed, the Certificates must be
endorsed or accompanied by appropriate bond powers, signed exactly as the name
or names of the registered owner(s) appear(s) on the Certificates, and also must

as the Company may require in accordance with the restrictions on transfer
applicable to the Original Notes. Signatures on such Certificates or bond powers

maintained at DTC. See Instruction 4.

     7. IRREGULARITIES. The Company will determine, in its sole discretion, all
questions as to the form of documents, validity, eligibility (including time of
receipt) and acceptance for exchange of any tender of Original Notes, which
determination shall be final and binding on all parties. The Company reserves
the absolute right to reject any and all tenders determined by it not to be in
proper form or the acceptance of which, or exchange for which, may, in the view
of counsel to the Company, be unlawful. The Company also reserves the absolute
right, subject to applicable law, to waive any of the conditions of the Exchange
Offer set forth in the Prospectus under "The Exchange Offer--Certain Conditions
to the Exchange Offer" or any conditions or irregularity in any tender of
Original Notes of any particular holder whether or not similar conditions or
irregularities are waived in the case of other holders. The Company's
interpretation of the terms and conditions of the Exchange Offer (including this
Letter of Transmittal and the instructions hereto) will be final and binding. No
tender of Original Notes will be 

                                      -14-
<PAGE>
 
deemed to have been validly made until all irregularities with respect to such
tender have been cured or waived. The Company, any of its affiliates or assigns
of the Company, the Exchange Agent, or any other person shall not be under any
duty to give notification of any irregularities in tenders or incur any
liability for failure to give such notification.

     8. QUESTIONS, REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES. Questions and
requests for assistance may be directed to the Exchange Agent at its address and
telephone number set forth on the front of this Letter of Transmittal.
Additional copies of the Prospectus, the Notice of Guaranteed Delivery and the
Letter of Transmittal may be obtained from the Exchange Agent or from your
broker, dealer, commercial bank, trust company or other nominee.

     9. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9. Under U.S. Federal income
tax law, a holder whose tendered Original Notes are accepted for exchange is
required to provide the Exchange Agent with such holder's correct taxpayer
identification number ("TIN") on Substitute Form W-9 below. If the Exchange
Agent is not provided with the correct TIN, the Internal Revenue Service (the
"IRS") may subject the holder or other payee to a $50 penalty. In addition,
payments to such holders or other payees with respect to Original Notes
exchanged pursuant to the Exchange Offer may be subject to 31% backup
withholding.

     The box in Part 2 of the Substitute Form W-9 may be checked if the
tendering holder has not been issued a TIN and has applied for a TIN or intends
to apply for a TIN in the near future. If the box in Part 2 is checked, the
holder or other payee must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 2 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Exchange Agent will
withhold 31% of all payments made prior to the time a properly certified TIN is
provided to the Exchange Agent. The Exchange Agent will retain such amounts
withheld during the 60 day period following the date of the Substitute Form W-9.
If the holder furnishes the Exchange Agent with its TIN within 60 days after the
date of the Substitute Form W-9, the amounts retained during the 60 day period
will be remitted to the holder and no further amounts shall be retained or
withheld from payments made to the holder thereafter. If, however, the holder
has not provided the Exchange Agent with its TIN within such 60 day period,
amounts withheld will be remitted to the IRS as backup withholding. In addition,
31% of all payments made thereafter will be withheld and remitted to the IRS
 until a correct TIN is provided.

     The holder is required to give the Exchange Agent the TIN (e.g., social
security number or employer identification number) of the registered owner of
the Original Notes or of the last transferee appearing on the transfers attached
to, or endorsed on, the Original Notes. If the Original Notes are registered in
more than one name or are not in the name of the actual owner, consult the
enclosed "Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9" for additional guidance on which number to report.

                                      -15-
<PAGE>
 
     Certain holders (including, among others, corporations, financial
institutions and certain foreign persons) may not be subject to these backup
withholding and reporting requirements. Such holders should nevertheless
complete the attached Substitute Form W-9 below, and write "exempt" on the face
thereof, to avoid possible erroneous backup withholding. A foreign person may
qualify as an exempt recipient by submitting a properly completed IRS Form W-8,
signed under penalties of perjury, attesting to that holder's exempt status.
Please consult the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional guidance on which
holders are exempt from backup withholding.

     Backup withholding is not an additional U.S. Federal income tax. Rather,
the U.S. Federal income tax liability of a person subject to backup withholding
will be reduced by the amount of tax withheld. If withholding results in an
overpayment of taxes, a refund may be obtained.

     10. WAIVER OF CONDITIONS. The Company reserves the absolute right to waive
satisfaction of any or all conditions enumerated in the Prospectus. 11. NO
CONDITIONAL TENDERS. No alternative, conditional, irregular or contingent
tenders will be accepted. All tendering holders of Original Notes, by execution
of this Letter of Transmittal, shall waive any right to receive notice of the
acceptance of their Original Notes for exchanges.

     Neither the Company, the Exchange Agent nor any other person is obligated
to given notice of any defect or irregularity with respect to any tender of
Original Notes nor shall any of them incur any liability for failure to give any
such notice.

     12. LOST, DESTROYED OR STOLEN CERTIFICATES. If any Certificate(s)
representing Original Notes have been lost, destroyed or stolen, the holder
should promptly notify the Exchange Agent. The holder will then be instructed as
to the steps that must be taken in order to replace the Certificate(s). This
Letter of Transmittal and related documents cannot be processed until the
procedures for replacing lost, destroyed or stolen Certificate(s) have been
followed.

     13. SECURITY TRANSFER TAXES. Holders who tender their Original Notes for
exchange will not be obligated to pay any transfer taxes in connection
therewith. If, however, Exchange Notes are to be delivered to, or are to be
issued in the name of, any person other than the registered holder of the
Original Notes tendered, or if a transfer tax is imposed for any reason other
than the exchange of Original Notes in connection with the Exchange Offer, then
the amount of any such transfer tax (whether imposed on the registered holder or
any other person) will be payable by the tendering holder. If satisfactory
evidence of payment of such taxes or exemption therefrom is not submitted with
the Letter of Transmittal, the amount of such transfer taxes will be billed
directly to such tendering holder.
