ITEM 1. Business

General

  ADVO, Inc. ("ADVO" or the "Company") is a direct mail marketing firm
primarily engaged in soliciting and processing printed advertising from
retailers, manufacturers and service companies for targeted distribution by
both shared and solo mail, as well as hand delivery, to consumer households in
the United States on a national, regional and local basis. Founded in 1929 as
a hand delivery company, the Company entered the direct mail industry as a
solo mailer in 1946 and began its shared mail program in 1980. The Company
currently is the largest commercial user of standard mail (formerly third-
class mail) in the United States.

  ADVO competes primarily with newspapers, direct mail companies, broadcast
media, periodicals and other local distribution entities for retail
advertising expenditures. The Company believes that direct mail, which enables
advertisers to target advertisements to specific customers or geographic
areas, is the most efficient vehicle for delivering printed advertising on a
saturation or full market coverage basis, as well as an effective means of
targeted coverage.

  ADVO's principal executive offices are located at One Univac Lane, Windsor,
Connecticut 06095.

Products and Services

  ADVO's direct mail marketing products and services include shared mail and
solo mail. ADVO provides ancillary services in conjunction with its direct
mail marketing programs and also provides private carrier (hand) delivery in
certain markets. In addition, the Company provides direct-mail advertising
solutions for local neighborhood businesses utilizing an envelope format.

Shared Mail

  In the Company's branded shared mail program (ShopWise(TM)), the
advertisements of several advertisers are combined into a single mail package.

  The Company assembles shared mail packages by targeting levels selected by
the customer. In most instances, each household within the predetermined
targeting level will receive a mail package. The Company offers various
targeting levels for the designated mailing area of the customer's
distribution based on the level of geo-demographic precision that is requested
by the customer. Individual customers can choose predetermined clusters of ZIP
Code zones, all ZIP Codes covered by the program, and ADVO Targeting Zones
("ATZs"). ATZs enable advertisers to target their ads to consumer clusters of
about 3,500 households. ATZs are neighboring postal carrier delivery routes
within a ZIP Code that are clustered together based on shared demographic
characteristics and proximity to key retail shopping areas.

  The flexibility and targeting capabilities of the ATZ platform enables
customers, such as retail store chains, to select areas serviced by their
retail stores and, at the same time, distribute different versions to reach
their choice consumers. The Company uses geographic, demographic and
psychographic data to tailor the customers' advertisements to their targeted
audience.

  The Company's shared mail program offers the features of penetration and
target marketing at a significant cost reduction when compared to mailing on
an individual or solo mail basis. This cost advantage is available because the
Company pays the total postage expense, and advertisers are generally charged
a selling price based upon, among other factors, the incremental weight of
their promotional pieces.


                                       1
<PAGE>

  As a part of its shared mail program, the Company provides the addresses of
the households receiving the mail packages, sorts, processes and transports
the advertising material for ultimate delivery through the United States
Postal Service ("USPS"). Generally, larger businesses, such as food chains and
mass merchandisers, will provide the Company with preprinted advertising
materials in predetermined quantities. In the case of manufacturers and small
retail customers, the Company may perform graphics services and/or act as a
broker for the required printing. The Company also offers shared mail
customers numerous standard turnkey advertising products in a variety of sizes
and colors.

  The Company believes its shared mail program is the largest program of its
kind.

  ShopWise(TM) is a weekly distribution program with coverage, on average, of
60 million households in approximately 120 markets. This program is used by
local and national retailers. The zone configuration selected for each market
is normally determined by population density and by proximity to retail
outlets. Retailers with multiple locations and weekly frequency have a great
influence on the zones chosen by the Company for its weekly distribution. The
Company derives most of its revenues from the ShopWise(TM) shared mail
program.

  The Company is part of a network, known as ADVO National Network Extension
("A.N.N.E.") comprised of regional shared mail companies, which provide its
clients with extended coverage outside the markets already served by the
Company. Approximately an additional 30 million households can be reached on a
shared mail basis through A.N.N.E. The Company handles the clients' orders
directly and manages distribution of their advertising through A.N.N.E.'s
partners. Conversely, A.N.N.E. enables participating partners (shared mail
companies) to offer their clients extended marketplace reach using the
Company's household coverage.

Solo Mail

  Solo mail services include addressing and processing brochures and circulars
for an individual customer for distribution through the USPS. Each customer
bears the full cost of postage and handling for each mailing. Customers
choosing this form of direct mail are generally those who wish to maintain an
exclusive image and complete control over the timing and the target of their
mailings.

  The Company processes solo mail using its own mailing list or lists supplied
by the customer. The Company charges a processing fee based on the solo mail
services rendered.

Other Products and Services

  The Company rents portions of its mailing list, through a specialized firm
hired by the Company, to organizations interested in distributing their own
mailings. The Company may or may not perform the associated distribution
services for the customer.

  During fiscal 1998, the Company acquired The Mailhouse, Inc., a franchise-
based cooperative coupon envelope mail company headquartered in Avon, MA. The
company was renamed MailCoups, Inc. ("MailCoups") and operates as a subsidiary
of ADVO. This subsidiary, operating under the trade name of Super Coups, is a
leader in creating and distributing attractive, cost-effective targeted
coupons in a distinctive envelope format for local neighborhood merchants via
an extended network of franchise owners. At the end of fiscal 2000, MailCoups
had approximately 338 franchise units in 26 states and directly employed 164
people.

  During fiscal 2000 the Company established a new subsidiary, ShopWise.com to
focus on the continuing development of the Company's Internet-related business
initiatives, including e-commerce related print advertising, CD-ROM insertion
capabilities and on-line concepts. As part of the ShopWise.com subsidiary, the
company acquired a controlling interest in Netserts, an advertising

                                       2
<PAGE>

magazine dedicated to driving on-line traffic to Internet sites by off-line
print advertising. Netserts, which reaches approximately 10 million households
on selected dates throughout the year, is delivered within the ShopWise(TM)
shared mail package.

  The Company executed two strategic initiatives during fiscal 2000;
partnering with a newspaper to offer clients a new integrated print
advertising solution and the introduction of additional in-home mailing dates
in two of its markets.

  Subsequent to year end, on November 2, 2000, the Company announced the
acquisition of Mail Marketing Systems, Inc., ("MMSI") a privately held direct
mail advertising company. This acquisition will be accounted for under the
purchase method of accounting and, accordingly, the results of operations of
the acquired company will be included in the consolidated statements of
operations from its acquisition date. The acquisition of MMSI complements
ADVO's core distribution network by providing additional shared mail coverage
in market areas not served by ADVO prior to the acquisition.

Mailing List

  ADVO's management believes its computerized mailing list is the largest
residential/household mailing list in the country. It contains over 119
million delivery points (constituting nearly all of the households in the
United States). The Company's management believes that the list is
particularly valuable and that replication in its entirety by competitors
would be extremely difficult and costly. The list enables the Company to
target mailings to best serve its customers.

  Bimonthly, ADVO receives the latest release of delivery point information
from the USPS. During the off months, ADVO receives a file release, which
includes only significant changes or approximately five to ten percent of the
base file. Included in these releases is information that indicates whether
the address is still occupied, whether the address still exists at all (i.e.,
demolished buildings) and any new addresses included in the ZIP Code (i.e.,
new construction). The USPS also indicates to ADVO changes in the walk
sequence order of addresses, which allows ADVO to qualify for the lowest
possible postage rates. The USPS provides these updates to any user for a fee,
provided that the user's list is at least 90% accurate on a ZIP Code basis.
ADVO believes its list is nearly 100% accurate.

Customer Base

  Typically, the Company's customers are those businesses whose products and
services are used by the general population. These businesses (supermarkets,
fast food, drug stores, discount and department stores and home furnishings
retailers) require continuous advertising to a mass audience. The enhanced
targeting capabilities of the Company's distribution system has lead to the
development of opportunities for new customer categories, such as,
telecommunications, insurance, financial services, entertainment and Internet
companies. In fiscal 2000 and 1999, due to the consolidation of two of the
Company's customers, no one customer accounted for more than 6% and 7%
respectively, of the Company's sales. No one customer accounted for more than
4% of the Company's sales in fiscal 1998.

Operations

  Customers' advertising circulars are processed by approximately 1,800
production employees who work at 20 mail processing facilities which are
strategically located throughout the nation. Inserting machines (which combine
the individual advertising pieces into the mailing packages), addressing and
labeling equipment are the principal pieces of equipment used to process the
Company's products and services. At several of the Company's production
facilities, the Alphaliner, a new computerized mail collator/inserter, is
being utilized. The Alphaliner offers higher speed and capacity, enhanced

                                       3
<PAGE>

productivity, computerized controls which automates order processing,
electronically integrates with other machines, and links to ADVO's order
fulfillment system. The Company has begun the process of integrating the
Alphaliner technology into many of its mail processing facilities. Conversion
of the remaining facilities will continue over the next four to five years.

  In all 20 of ADVO's mail processing facilities, the USPS accepts and
verifies the Company's mail to help ensure rapid package acceptance and
distribution, which benefits both the USPS and the Company. In most instances,
the mail is then shipped by the Company to the destination office of the USPS
for final delivery.

  MailCoups operates a cooperative direct mail coupon envelope advertising
business by performing printing and distribution services for the franchisees
at their one production facility.

  The Company entered into an agreement with IBM Global Services ("IBM"), to
provide computer processing, systems development, and systems legacy support
to the Company. The Company's regions, sales offices and corporate
headquarters are on-line with this computer center which enables the day-to-
day processing functions to be performed and provides corporate headquarters
with management information. The systems include: order processing and
production control, transportation/distribution, address list maintenance,
market analysis, label printing and distribution, billing and financial
systems, and carrier routing of addresses received from customer files and
demographic analyses. The Company also has agreements with IBM to provide for
a customer support center (help desk) and client server (server farm)
management services.

Competition

  In general, the printed advertising market is highly competitive with
companies competing primarily on the basis of price, speed of delivery and
ability to target selected potential customers on a cost-effective basis.
ADVO's competitors for the delivery of retail and other printed advertising
are numerous, and include newspapers, regional and local mailers, direct
marketing firms, "shoppers" and "pennysavers."

  Newspapers represent the Company's most significant and direct competition.
Through the distribution of preprinted circulars, classified advertising and
run of press advertising ("ROP"), newspapers have been the traditional and
dominant medium for advertising by retailers for many years. Insertion rates
are highly competitive and many newspapers' financial resources are
substantial.

  ADVO's principal direct marketing competitors are other companies with
residential lists and similar cooperative mailing programs. These companies
have a significant presence in many of the Company's markets and represent
serious competition to the Company's ShopWise(TM) shared mail program in those
markets.

  There are local mailers in practically every market of the country. In
addition to local mailers, there are many local private delivery services such
as shoppers and pennysavers which compete by selling ROP advertisements and
classified advertisements. ADVO believes that it competes effectively in its
various markets.

Seasonality

  ADVO's business generally follows the trends of retail advertising spending.
The Company has historically experienced higher revenues in the second half of
the calendar year.

Research and Development

  Expenditures of the Company in research and development during the last
three years have not been material.

                                       4
<PAGE>

Environmental Matters

  The Company believes that it is substantially in compliance with all
regulations concerning the discharge of materials into the environment, and
such regulations have not had a material effect on the capital expenditures or
operations of the Company.

Raw Materials

  The Company manages approximately 45,000 tons of paper per year through its
printing network on behalf of its print vendors. ADVO has agreements with
various paper suppliers and print vendors to assure continuity of supply as
well as supply of proper paper grades at competitive prices.

Employees

  As of September 30, 2000, the Company had a total of approximately 3,900
full and part-time employees. ADVO also uses outside temporary employees for
the outsourcing of certain production jobs and during busy seasons.

  ADVO has one union contract, covering production employees in the Hartford,
Connecticut branch. The Company believes that its relations with its employees
are satisfactory.
