 Dear Shareholder:                                         June 19, 1997     
    
   We are pleased to invite you to a Special Meeting of Shareholders of
 Atlantes Corporation ("Atlantes") to be held on June 30, 1997, at 2:00
 P.M., local time, at the offices of Atlantes, 90 Madison Street, Denver,
 Colorado.     
 
   Atlantes has entered into an Agreement and Plan of Merger (the "Merger
 Agreement") dated as of May 17, 1997 among Metromail Corporation
 ("Metromail"), MML Merging Company, a wholly-owned subsidiary of Metromail
 ("Mergerco"), and Atlantes pursuant to which Mergerco would merge with and
 into Atlantes (the "Merger") and the shareholders of Atlantes would receive
 for each share of Common Stock, no par value, of Atlantes ("Atlantes Common
 Stock"), held by them immediately prior to the Effective Time of the Merger
 (1) 1.241 shares of Common Stock, $.01 par value, of Metromail ("Metromail
 Common Stock"), or, at the election of the holder thereof but subject to
 certain limitations, $25.99 in cash plus (2) the right to receive shares of
 Metromail Common Stock depending on the achievement of certain performance
 targets. At the Special Meeting, you will be asked to approve the Merger
 Agreement and to approve, as part of the Merger Agreement, the acceleration
 of vesting of unvested stock options held by the Chairman of the Board of
 Atlantes that could otherwise result in "parachute payments" for federal
 income tax purposes (the "Parachute Proposal").
 
   After careful consideration, your Board of Directors unanimously approved
 the Merger Agreement and the transactions contemplated thereby. The Board
 believes that the proposed Merger is fair, equitable and in the best
 interests of Atlantes and its shareholders and recommends that you vote FOR
 the proposal to approve the Merger Agreement and FOR the Parachute
 Proposal. The accompanying Proxy Statement/Prospectus provides a detailed
 description of the proposed Merger. Please give this material your
 thoughtful attention.
 
   Approval of the Merger Agreement requires the affirmative vote of the
 holders of two-thirds of the outstanding shares of Atlantes Common Stock.
 It is a condition to the obligations of Metromail to proceed with the
 Merger that the Parachute Proposal be approved by holders of more than 75%
 of the shares of Atlantes Common Stock outstanding immediately prior to the
 Effective Time of the Merger (disregarding shares held by the Chairman).
 Accordingly, your vote is very important. To ensure that your shares are
 represented, please vote, date, sign and mail the enclosed proxy in the
 envelope provided, whether or not you expect to be present at the Special
 Meeting.
    
   Please notice that if you desire to elect to receive cash in lieu of the
 1.241 shares of Metromail Common Stock that you would otherwise receive
 upon consummation of the Merger in exchange for each of your shares of
 Atlantes Common Stock, you must submit the enclosed Form of Election, in
 accordance with the instructions on that form, no later than 5:00 P.M., New
 York time, on June 27, 1997.     
 
                                          Sincerely,
 
                                          E. Thomas Detmer, Jr.
                                          President
    
   Copies of the accompanying Proxy Statement/Prospectus are also being sent
 to holders of warrants and options to purchase shares of Atlantes Common
 Stock. Although such holders are not entitled to vote at the Special
 Meeting, we urge them to read carefully the accompanying Proxy
 Statement/Prospectus and Form of Election.

                   NOTICE OF SPECIAL MEETING OF SHAREHOLDERS
                          
                       TO BE HELD ON JUNE 30, 1997     
 
To the Shareholders of Atlantes Corporation:
   
  A Special Meeting of Shareholders of Atlantes Corporation ("Atlantes") will
be held at 2:00 P.M., local time, on June 30, 1997, at the offices of
Atlantes, 90 Madison Street, Denver, Colorado, for the following purposes:
    
    1. To consider and vote upon a proposal to approve the Agreement and Plan
  of Merger dated as of May 17, 1997 (the "Merger Agreement") among Metromail
  Corporation ("Metromail"), MML Merging Company, a wholly-owned subsidiary
  of Metromail ("Mergerco"), and Atlantes.
 
    2. To consider and vote upon a proposal to approve, as part of the Merger
  (as defined below), the acceleration of vesting of unvested stock options
  held by the Chairman of the Board of Atlantes that could otherwise result
  in "parachute payments" for federal income tax purposes (the "Parachute
  Proposal").
 
    3. To transact such other business as may be properly brought before the
  meeting.
 
  As described more fully in the accompanying Proxy Statement/Prospectus, the
Merger Agreement provides for, among other things:
 
    (i) the merger (the "Merger") of Mergerco with and into Atlantes; and
 
    (ii) the conversion of each share of Common Stock, no par value, of
  Atlantes ("Atlantes Common Stock") outstanding immediately prior to the
  Merger (other than shares held by Atlantes shareholders who properly
  exercise their dissenters' rights under Colorado law) into (1) 1.241 shares
  of Common Stock, $.01 par value, of Metromail ("Metromail Common Stock"),
  or, at the election of the holder thereof but subject to certain
  limitations, $25.99 in cash, plus (2) the right to receive shares of
  Metromail Common Stock in the years 1999 through 2002 depending on the
  achievement of certain performance targets in years 1998 through 2001.
 
  After careful consideration, your Board of Directors unanimously approved
the Merger Agreement. The Board recommends that you vote FOR the proposal to
approve the Merger Agreement and FOR the Parachute Proposal.
   
  Shareholders of record at the close of business on June 17, 1997 (the
"Record Date") are entitled to notice of and to vote at the meeting.     
 
  Under Colorado law, the affirmative vote of holders of two-thirds of the
shares of Atlantes Common Stock outstanding on the Record Date is required to
approve the Merger Agreement. It is a condition to the obligations of
Metromail to proceed with the Merger that the Parachute Proposal be approved
by holders of more than 75% of the shares of Atlantes Common Stock outstanding
immediately prior to the Merger (disregarding shares held by the Chairman). It
is, therefore, important that your shares be represented at the Special
Meeting regardless of the number of shares you may hold. ANY SHAREHOLDER HAS
THE RIGHT TO DISSENT AND TO RECEIVE PAYMENT OF THE FAIR VALUE OF THE
SHAREHOLDER'S SHARES OF ATLANTES COMMON STOCK UPON COMPLIANCE WITH ARTICLE 113
OF THE COLORADO BUSINESS CORPORATION ACT. FOR A DESCRIPTION OF DISSENTERS'
RIGHTS, SEE THE INFORMATION PROVIDED IN THE ACCOMPANYING PROXY
STATEMENT/PROSPECTUS UNDER THE CAPTION "DISSENTERS' RIGHTS." See also Annex B
to the accompanying Proxy Statement /Prospectus for the text of Article 113 of
the Colorado Business Corporation Act. Notwithstanding the above, under the
Merger Agreement, if the holders of more than 1% of Atlantes Common Stock
properly exercise dissenters' rights, Metromail will have the right to decline
to consummate the Merger.
 
  SHAREHOLDERS ARE URGED TO VOTE, SIGN AND MAIL THE ACCOMPANYING PROXY IN THE
ENVELOPE PROVIDED, WHETHER OR NOT THEY EXPECT TO BE PRESENT AT THE SPECIAL
MEETING.

  Please check to be certain of the manner in which your shares are
registered--whether individually, as joint tenants, or in a representative
capacity--and sign the proxy accordingly. Failure to do so may disqualify your
vote.

                             METROMAIL CORPORATION
                                  PROSPECTUS
 
                                --------------
   
  This Proxy Statement/Prospectus ("Proxy Statement/Prospectus") is being
furnished to the holders of Common Stock, no par value ("Atlantes Common
Stock"), of Atlantes Corporation, a Colorado corporation ("Atlantes"), in
connection with the solicitation of proxies by the Board of Directors of
Atlantes (the "Atlantes Board") for use at its Special Meeting of Shareholders
to be held at the offices of Atlantes, 90 Madison Street, Denver, Colorado, on
June 30, 1997 at 2:00 p.m., local time, and any adjournments thereof (the
"Atlantes Special Meeting").     
 
  This Proxy Statement/Prospectus relates to the Agreement and Plan of Merger
dated as of May 17, 1997 (the "Merger Agreement") among Metromail Corporation,
a Delaware corporation ("Metromail"), MML Merging Company, a Colorado
corporation and wholly-owned subsidiary of Metromail ("Mergerco"), and
Atlantes. The Merger Agreement provides for the merger (the "Merger") of
Mergerco with and into Atlantes, with Atlantes surviving as a wholly-owned
subsidiary of Metromail. Subject to the terms and conditions of the Merger
Agreement, each share of Atlantes Common Stock outstanding immediately prior
to the Effective Time (as defined in the Merger Agreement) of the Merger will
be converted into (i) 1.241 shares of Common Stock, $.01 par value, of
Metromail ("Metromail Common Stock"), or, at the election of the holder
thereof but subject to certain limitations, $25.99 in cash, plus (ii) the
right to receive shares of Metromail Common Stock in years 1999 through 2002
depending on the achievement of certain performance targets in years 1998
through 2001. Each share of Metromail Common Stock issued pursuant to the
Merger will be accompanied by a right (the "Metromail Right") to purchase from
Metromail one one-thousandth of a share of Junior Participating Preferred
Stock, Series A (the "Metromail Series A Preferred Stock"), subject to the
provisions described under "DESCRIPTION OF METROMAIL COMMON STOCK--Certain
Charter and By-law Provisions; Metromail Rights Agreement." Notwithstanding
the foregoing, holders of Atlantes Common Stock have the right to dissent from
the Merger and to receive payment of the fair value of their stock upon full
compliance with Article 113 of the Colorado Business Corporation Act (the
"CBCA"). See "DISSENTERS' RIGHTS." If holders of more than 1% of the shares of
Atlantes Common Stock outstanding immediately prior to the Effective Time
properly demand dissenters' rights, Metromail will have the right to decline
to consummate the Merger. See "THE MERGER AGREEMENT--Conditions Precedent to
the Merger."
   
  HOLDERS OF ATLANTES COMMON STOCK WHO WISH TO RECEIVE CASH IN LIEU OF THE
1.241 SHARES OF METROMAIL COMMON STOCK THAT THEY WOULD RECEIVE IN EXCHANGE FOR
EACH OF THEIR SHARES OF ATLANTES COMMON STOCK UPON CONSUMMATION OF THE MERGER
MUST RETURN THE FORM OF ELECTION THAT ACCOMPANIES THIS PROXY
STATEMENT/PROSPECTUS TO THE EXCHANGE AGENT (AS DEFINED HEREIN) BY 5:00 P.M.,
NEW YORK TIME, ON JUNE 27, 1997. HOLDERS OF ATLANTES COMMON STOCK WHO DO NOT
WISH TO RECEIVE CASH INSTEAD OF SHARES OF METROMAIL COMMON STOCK NEED NOT
RETURN SUCH FORM OF ELECTION. SEE "THE MERGER AGREEMENT--CASH ELECTION."     
 
  SHAREHOLDERS OF ATLANTES AND HOLDERS OF ATLANTES STOCK OPTIONS AND WARRANTS
SHOULD CONSIDER CAREFULLY ALL OF THE INFORMATION CONTAINED IN THIS PROXY
STATEMENT/PROSPECTUS INCLUDING, IN PARTICULAR, THE FACTORS DISCUSSED UNDER THE
HEADING "RISK FACTORS" BEGINNING ON PAGE 11.
 
  The consummation of the Merger is subject, among other things, to the
approval of the Merger Agreement by two-thirds of the votes entitled to be
cast at the Atlantes Special Meeting. It is also a condition to the
obligations of Metromail that the acceleration of vesting of unvested stock
options held by the Chairman of the Board of Atlantes that could otherwise
result in "parachute payments" for federal income tax purposes be approved by
the holders of more than 75% of the shares of Atlantes outstanding immediately
prior to the Effective Time (disregarding shares held by the Chairman).
 
  This Proxy Statement/Prospectus also constitutes the Prospectus of Metromail
filed as part of a Registration Statement on Form S-4 (the "Registration
Statement") with the Securities and Exchange Commission (the "SEC") under the
Securities Act of 1933, as amended (the "Securities Act"), relating to the
shares of Metromail Common Stock which may be issued pursuant to the Merger.

                            ATLANTES SPECIAL MEETING
   
  Date, Place and Time. The Atlantes Special Meeting will be held on June 30,
1997 at 2:00 p.m., local time, at the offices of Atlantes, 90 Madison Street,
Denver, Colorado.     
 
  Purpose. To consider and vote upon (i) a proposal to approve the Merger
Agreement and (ii) a proposal to approve, as part of the Merger Agreement, the
acceleration of vesting of unvested stock options held by the Chairman of the
Board of Atlantes that could otherwise result in "parachute payments" for
federal income tax purposes (the "Parachute Proposal") and to transact such
other business as may properly come before the Atlantes Special Meeting. See
"ATLANTES SPECIAL MEETING--Purpose."
   
  Record Date; Voting Rights. Only holders of record of Atlantes Common Stock
at the close of business on June 17, 1997 (the "Atlantes Record Date") are
entitled to receive notice of and to vote at the Atlantes Special Meeting. At
the close of business on the Atlantes Record Date, there were 476,803 shares of
Atlantes Common Stock outstanding, each of which entitles the registered holder
thereof to one vote on each matter voted upon at the Atlantes Special Meeting.
See "ATLANTES SPECIAL MEETING--Record Date; Voting Rights."     
 
  Quorum. The holders of a majority of the shares of Atlantes Common Stock
outstanding and entitled to vote must be present in person or represented by
proxy at the Atlantes Special Meeting in order for a quorum to be present. In
the event that a quorum is not present at the Atlantes Special Meeting, it is
expected that such meeting will be adjourned or postponed to allow for the
solicitation of additional proxies. See "ATLANTES SPECIAL MEETING--Quorum."
 
  Required Vote. Approval of the Merger Agreement will require the affirmative
vote of the holders of two-thirds of the shares of Atlantes Common Stock
outstanding on the Atlantes Record Date. Approval of the Parachute Proposal
will require the affirmative vote of the holders of at least 75% of the shares
of Atlantes Common Stock outstanding immediately prior to the Effective Time of
the Merger, other than the shares held by the Chairman of Atlantes. If the
holders of all outstanding Atlantes Warrants were to exercise such warrants
prior to the Effective Time (assuming no holders of Atlantes Stock Options were
to exercise such options), the holders of approximately 91% of the shares of
Atlantes Common Stock outstanding on the Atlantes Record Date (disregarding
shares held by the Chairman) would be required to approve the Parachute
Proposal. See "ATLANTES SPECIAL MEETING--Required Vote" and "PARACHUTE
PROPOSAL."
 
  Voting Agreements. The holders of 193,760 shares of Atlantes Common Stock
outstanding at the close of business on the Atlantes Record Date (approximately
40.6% of the shares of Atlantes Common Stock then
 
                                       2
<PAGE>
 
outstanding) have signed agreements obligating them to vote in favor of
approval of the Merger Agreement and the Parachute Proposal and against certain
other actions. See "VOTING AGREEMENTS."
 
  Share Ownership of Management. At the close of business on the Atlantes
Record Date, directors and executive officers of Atlantes were the record
owners of an aggregate of 153,321 (approximately 32.2%) of the shares of
Atlantes Common Stock then outstanding. Such shares do not include the shares
subject to the voting agreements described above. Atlantes expects that all
such shares will be voted in favor of approval of the Merger Agreement and the
Parachute Proposal. See "ATLANTES SPECIAL MEETING--Required Vote."
 
                        PARTIES TO THE MERGER AGREEMENT
 
  Metromail. Metromail is a leading provider of database marketing, direct

  Mergerco. Mergerco was incorporated in Colorado on May 7, 1997 solely for the
purpose of consummating the Merger and the other transactions contemplated by
the Merger Agreement. Mergerco has minimal assets and no business and has
carried on no activities which are not directly related to its formation and
its execution of the Merger Agreement. Its principal executive offices are
located at 360 East 22nd Street, Lombard, Illinois 60148, and its telephone
number is (630) 620-3300.
 
                                   THE MERGER
 
  Recommendation of the Atlantes Board. The Board of Directors of Atlantes (the
"Atlantes Board") has unanimously determined that the Merger is fair, equitable
and in the best interests of Atlantes and its shareholders and has unanimously
approved the Merger Agreement. THE ATLANTES BOARD UNANIMOUSLY RECOMMENDS THAT
THE SHAREHOLDERS OF ATLANTES VOTE IN FAVOR OF APPROVAL OF THE MERGER AGREEMENT
AND IN FAVOR OF THE PARACHUTE PROPOSAL AT THE ATLANTES SPECIAL MEETING. See
"THE MERGER--Atlantes' Reasons for the Merger; Recommendation of its Board of
Directors."
 
  Opinion of Financial Advisor. The Wallach Company, Inc. ("The Wallach
Company") has delivered its written opinion, dated May 17, 1997 (the "Fairness
Opinion"), to the Atlantes Board to the effect that, subject to the various
considerations set forth in such opinion, as of that date the consideration to
be received in the Merger by Atlantes shareholders was fair to Atlantes'
shareholders from a financial point of view. For information on the assumptions
made, matters considered and limits of the review by The Wallach Company, see
"THE MERGER--Opinion of Atlantes' Financial Advisor." Holders of Atlantes
Common Stock are urged to read carefully and in its entirety the Fairness
Opinion, a copy of which appears as Annex C to this Proxy Statement/Prospectus.
 
                                       3

  Interests of Certain Persons in the Merger. Certain executive officers of
Atlantes, one of whom is also a director of Atlantes, have interests in the
Merger in addition to their interests as shareholders of Atlantes. In
connection with the execution of the Merger Agreement, Metromail entered into
employment agreements (the "Employment Agreements") with Mr. E. Thomas Detmer,
Jr., President of Atlantes, Mr. William Anderson, Vice President--Operations of
Atlantes, and Mr. Peter A. O'Neil, Vice President--Client Services of Atlantes,
which are conditioned upon consummation of the Merger in accordance with the
terms of the Merger Agreement. Shares of Atlantes Common Stock, Atlantes Stock
Options and Atlantes Warrants held by executive officers and directors of
Atlantes will be converted pursuant to the Merger in the same manner as those
held by other holders. See "THE MERGER--Interests of Certain Persons in the
Merger."
   
  Material Federal Income Tax Consequences. For a description of certain
material federal income tax consequences of the Merger, see "THE MERGER--
Certain Material Federal Income Tax Consequences." Holders of Atlantes Common
Stock, Atlantes Stock Options and Atlantes Warrants are urged to consult with
their own tax advisors with respect to the potential tax effects of the
proposed Merger on such holders.     
 
  Anticipated Accounting Treatment. The Merger will be accounted for as a
"purchase" for accounting and financial reporting purposes in accordance with
Accounting Principles Board Opinion No. 16 ("APB No. 16"). For purposes of
preparing Metromail's consolidated financial statements, Metromail will
establish a new accounting basis for Atlantes's assets and liabilities based
upon the fair values thereof and Metromail's purchase price, including the
direct costs of the acquisition. A final determination of required purchase
accounting adjustments and of the fair value of the assets and liabilities of
Atlantes has not yet been made. Accordingly, the purchase accounting
adjustments made in connection with the development of the pro forma financial
information appearing elsewhere in this Proxy Statement/Prospectus are
preliminary and are subject to adjustment. After the Merger, Metromail will
undertake a study to determine the fair value of Atlantes's assets and
liabilities and will make appropriate purchase accounting adjustments upon
completion of such study. For financial reporting purposes, Metromail will
consolidate the results of Atlantes's operations with those of Metromail's
operations, beginning with the consummation of the Merger, but Metromail's
financial statements for prior periods will not be restated as a result of the
Merger. See "THE MERGER--Anticipated Accounting Treatment."
 
                              THE MERGER AGREEMENT
 
  Conversion of Shares in the Merger. At the Effective Time of the Merger,
Mergerco will be merged with and into Atlantes, with Atlantes continuing as the
surviving corporation (the "Surviving Corporation") and a wholly-owned
subsidiary of Metromail. As a result of the Merger, the separate corporate
existence of Mergerco will cease, and Atlantes will succeed to all the rights
and be responsible for all the obligations of Mergerco in accordance with the
CBCA. Subject to the terms and conditions of the Merger Agreement, each share
of Atlantes Common Stock outstanding immediately prior to the Effective Time of
the Merger will be converted into (i) 1.241 shares of Metromail Common Stock
or, at the election of the holder thereof but subject to certain limitations,
$25.99 in cash, plus (ii) the right to receive shares of Metromail Common Stock
in years 1999 through 2002 depending on the achievement of certain performance
targets in years 1998 through 2001 ("Contingent Shares"), as described below.
Each share of Metromail Common Stock issued pursuant to the Merger will be
accompanied by a Metromail Right, subject to the provisions described under
"DESCRIPTION OF METROMAIL COMMON STOCK--Certain Charter and By-law Provisions;
Metromail Rights Agreement." Cash will be paid in lieu of any fractional share
of Metromail Common Stock. Notwithstanding the foregoing, holders of Atlantes
Common Stock have the right to dissent from the Merger and to receive payment
of the fair value of their stock upon full compliance with Article 113 of the
CBCA. If holders of more than 1% of the shares of Atlantes Common Stock
outstanding immediately prior to the Effective Time properly exercise
dissenters' rights, Metromail will have the right to decline to consummate the
Merger. See "THE MERGER AGREEMENT--Conversion of Shares in the Merger," "--Cash
Election," "--No Fractional Shares," "--Adjustment of Exchange Ratio," "--
Contingent Shares" and "--Conditions Precedent to the Merger" and "DISSENTERS'
RIGHTS."
 
                                       4

  HOLDERS OF ATLANTES COMMON STOCK WHO WISH TO RECEIVE CASH IN LIEU OF THE
1.241 SHARES OF METROMAIL COMMON STOCK THAT THEY WOULD RECEIVE IN EXCHANGE FOR
EACH OF THEIR SHARES OF ATLANTES COMMON STOCK UPON CONSUMMATION OF THE MERGER
MUST RETURN THE FORM OF ELECTION THAT ACCOMPANIES THIS PROXY
STATEMENT/PROSPECTUS TO AMERICAN STOCK TRANSFER AND TRUST COMPANY (THE
"EXCHANGE AGENT") BY 5:00 P.M., NEW YORK TIME, ON JUNE 27, 1997. HOLDERS OF
ATLANTES COMMON STOCK WHO DO NOT WISH TO RECEIVE CASH INSTEAD OF SHARES OF
METROMAIL COMMON STOCK NEED NOT RETURN SUCH FORM OF ELECTION. SEE "THE MERGER
AGREEMENT--CASH ELECTION."     
 
  Contingent Shares. Each holder of Atlantes Common Stock, Atlantes Warrants or
Atlantes Stock Options immediately prior to the Effective Time (each, a "Record
Holder") will be entitled to receive Contingent Shares in the years 1999
through 2002 depending on the achievement of certain performance targets in
each of the calendar years ending December 31, 1998 through 2001. The
performance targets are based upon the number of Qualifying Records (as defined
herein) loaded into Atlantes's or Metromail's database during each such
calendar year. If all performance targets are met, the Record Holders will be
entitled to receive Contingent Shares having a value (based on an average price
of Metromail Common Stock over a period of ten consecutive trading days ending
five trading days before the delivery date), in the aggregate, of $12,500,000,
subject to certain limitations and subject to reduction in the event Metromail
incurs certain losses and expenses that it is permitted to offset against the
amounts otherwise payable. The allocation of Contingent Shares among Record
Holders who held Atlantes Common Stock, Atlantes Warrants and Atlantes Stock
Options is intended to place each holder of Atlantes Warrants or Atlantes Stock
Options in the same position with respect to Contingent Shares as if the holder
had exercised the Atlantes Warrants or Atlantes Stock Options prior to the
Merger. Following the occurrence of certain Exceptional Events (as defined
herein), the Record Holders's right to receive Contingent Shares will become
fixed and will no longer be based upon prospective achievement of performance
targets. See "THE MERGER AGREEMENT--Contingent Shares."
 
  Atlantes Warrants. At the Effective Time of the Merger, each Atlantes Warrant
outstanding immediately prior to the Effective Time will be converted into (i)
1.193 shares of Metromail Common Stock or, at the election of the holder but
subject to certain limitations, $24.99 in cash, plus (ii) the right to receive
Contingent Shares. See "THE MERGER AGREEMENT--Atlantes Warrants" and "--Cash
Election." Holders of Atlantes Warrants will receive a notice from Atlantes
notifying them of their rights to exercise Atlantes Warrants before the Merger
and receive Atlantes Common Stock before the Merger. A holder of Atlantes
Warrants who exercises Atlantes Warrants and receives Atlantes Common Stock and
who exchanges Atlantes Common Stock for Metromail Common Stock in accordance
with the Merger Agreement will have different tax consequences than a holder of
Atlantes Warrants who elects to exchange Atlantes Warrants directly for
Metromail Common Stock. See "THE MERGER--Certain Material Federal Income Tax
Consequences."
 
  Atlantes Stock Options. At the Effective Time of the Merger, each Atlantes
Stock Option outstanding immediately prior to the Effective Time will be
converted into (i) a specified number of shares of Metromail Common Stock
(1.193 shares for each Atlantes Stock Option with an exercise price of $1.00
per share; 1.181 shares for each Atlantes Stock Option with an exercise price
of $1.25 per share; 1.169 shares for each Atlantes Stock Option with an
exercise price of $1.50 per share; and 1.145 shares for each Atlantes Stock
Option with an exercise price of $2.00 per share), or, at the election of the
holder thereof, $25.99 less the applicable exercise price of the Atlantes Stock
Option in cash, plus (ii) the right to receive Contingent Shares. See "THE
MERGER AGREEMENT--Atlantes Stock Options" and "--Cash Election."
 
  Termination. The Merger Agreement may be terminated at any time prior to the
Effective Time, whether before or after approval by the shareholders of
Atlantes of the Merger Agreement : (i) by mutual written consent of Metromail
and Atlantes; (ii) by either Metromail or Atlantes if the other (or Mergerco if
Atlantes is the terminating party) has failed to comply in any material respect
with any of its covenants or agreements contained in the Merger Agreement
required to be complied with prior to the date of such termination or
materially
 
                                       5
<PAGE>
 
breaches any representation or warranty that is not qualified as to materiality
or breaches any representation or warranty that is so qualified (in each case
after a five business day cure period following notice of such breach) or if
the requisite shareholder approval is not obtained; or (iii) by either
Metromail or Atlantes if (A) the Merger has not been effected on or prior to
the close of business on August 31, 1997, subject to certain limitations, or
(B) any court or other governmental entity having jurisdiction has permanently
enjoined, restrained or otherwise prohibited the transactions contemplated by
the Merger Agreement by final and nonappealable order, decree, ruling or other
action. See "THE MERGER AGREEMENT--Termination."
 
  Fees and Expenses. The Merger Agreement provides that Metromail and Atlantes
will each pay their own respective costs and expenses incurred by it in
connection with the preparation, negotiation, execution, delivery and
performance of the Merger Agreement, except that Metromail will pay the fees of
The Wallach Company if the Merger is consummated. If certain costs and expenses
of Atlantes exceed specified amounts, Metromail will be entitled to offset such
excess against future Contingent Payment Amounts (as defined herein). See "THE
MERGER AGREEMENT--Fees and Expenses."
 
   COMPARATIVE RIGHTS OF STOCKHOLDERS; DESCRIPTION OF METROMAIL COMMON STOCK
 
  The rights of shareholders of Atlantes currently are governed by the CBCA and
Atlantes's Articles of Incorporation (the "Atlantes Charter") and By-laws (the
"Atlantes By-laws"). Upon consummation of the Merger, shareholders of Atlantes
will become stockholders of Metromail, which is a Delaware corporation, and
their rights as stockholders of Metromail will be governed by the Delaware
General Corporation Law (the "DGCL"), and Metromail's Third Amended and
Restated Certificate of Incorporation (the "Metromail Certificate of
Incorporation") and By-laws (the "Metromail By-laws"). See "COMPARISON OF THE
RIGHTS OF HOLDERS OF METROMAIL COMMON STOCK AND ATLANTES COMMON STOCK" for a
discussion of the material differences between the rights of holders of
Atlantes Common Stock and the rights of holders of Metromail Common Stock. See
"DESCRIPTION OF METROMAIL COMMON STOCK" for a description of Metromail Common
Stock.
 
                               DISSENTERS' RIGHTS
 
  Holders of Atlantes Common Stock have the right to dissent from the Merger
and to receive payment of the fair value of their shares upon full compliance
with Article 113 of the CBCA. A copy of Article 113 of the CBCA is attached
hereto as Annex B. If holders of more than 1% of the shares of Atlantes Common
Stock outstanding immediately prior to the Effective Time properly exercise
dissenters' rights, Metromail will have the right to decline to consummate the
Merger. See "DISSENTERS' RIGHTS" and "THE MERGER AGREEMENT--Conditions
Precedent to the Merger."

              COMPARATIVE PER SHARE DATA OF METROMAIL AND ATLANTES
 
  The following table sets forth certain selected per share data for Metromail
and Atlantes on historical and unaudited pro forma combined bases. The
unaudited pro forma financial data assume that the Merger had been consummated
at the beginning of the earliest period presented and give effect to the Merger
as a "purchase" under generally accepted accounting principles. Book value data
for all pro forma presentations is based upon the number of outstanding shares
of Metromail Common Stock adjusted to include the shares of Metromail Common
Stock expected to be issued in the Merger, assuming that no holder of Atlantes
Common Stock, Atlantes Warrants or Atlantes Options makes a cash election, and
no holder of Atlantes Warrants or Atlantes Options exercises such warrants or
options before the Effective Time, and disregarding the delivery of any
Contingent Shares. Based on these assumptions and the number of shares of
Atlantes Common Stock outstanding at the close of business on March 31, 1997,
holders of Atlantes Common Stock would receive an aggregate of 832,105 shares
of Metromail Common Stock upon consummation of the Merger. The information set
forth below should be read in conjunction with the historical Consolidated and
Combined Financial Statements of Metromail and the Financial Statements of
Atlantes, including the notes thereto, appearing elsewhere herein. See
"METROMAIL CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS" and "ATLANTES

                                 RISK FACTORS
 
  Shareholders of Atlantes and holders of Atlantes Stock Options and Atlantes
Warrants should carefully consider all of the information contained in this
Proxy Statement/Prospectus including, in particular, the following:
 
MERGER CONSIDERATION
 
  In determining whether to approve the transactions pursuant to the Merger
Agreement, shareholders of Atlantes should consider that the price of
Metromail Common Stock at the Effective Time as well as the prices at the date
of this Proxy Statement/Prospectus and at the date of the Atlantes Special
Meeting may vary as a result of changes in the business, operations or
prospects of Metromail, general market and economic conditions and other
factors. Although it is anticipated that the Effective Time will occur shortly
after the Atlantes Special Meeting, the Effective Time may occur at a later
date than the date of the Atlantes Special Meeting, and thus, there can be no
assurance that the sales price of Metromail Common Stock on the date of the
Atlantes Special Meeting will be indicative of the sales price of Metromail
Common Stock at or after the Effective Time. Shareholders of Atlantes should
also consider that the number of shares of Metromail Common Stock to be
delivered upon consummation of the Merger upon conversion of Atlantes Common
Stock, Atlantes Warrants and Atlantes Stock Options (other than Contingent
Shares) is fixed pursuant to the Merger Agreement. Changes in the price of
Metromail Common Stock will not result in an adjustment to such number and any
such changes will not, in and of themselves, constitute a basis for either
party to terminate the Merger Agreement. See "THE MERGER AGREEMENT--Conversion
of Shares in the Merger," "--Atlantes Warrants," and "--Atlantes Stock
Options."
 
  THERE CAN BE NO ASSURANCE WITH RESPECT TO ANY MARKET PRICE OF METROMAIL
COMMON STOCK. BROAD MARKET FLUCTUATIONS, AS WELL AS GENERAL ECONOMIC OR
POLITICAL CONDITIONS, MAY ADVERSELY AFFECT THE MARKET PRICE OF THE METROMAIL
COMMON STOCK, REGARDLESS OF THE ACTUAL PERFORMANCE OF METROMAIL.
   
  Pursuant to the Merger Agreement, holders of Atlantes Common Stock, Atlantes
Warrants and Atlantes Stock Options immediately prior to the Effective Time
will be entitled to receive Contingent Shares in 1999 through 2002 depending
on the achievement of certain performance targets in 1998 through 2001. The
number of Contingent Shares to be delivered with respect to any Measurement
Period (as defined herein) is determined first by calculating the "Contingent
Payment Amount." This is determined by comparing the number of customer
response cards that meet certain specifications, the data from which is loaded
into Atlantes' or Metromail's database during the particular Measurement
Period, to the specified performance targets. The Contingent Payment Amount is
subject to reduction if Metromail incurs certain losses and expenses that it
is permitted to offset against such amount. The number of Contingent Shares to
be delivered is equal to the Contingent Payment Amount, as it may be so
reduced, divided by the average of the per share closing prices on the NYSE of
Metromail Common Stock during the ten consecutive trading days ending on the
trading day which is five trading days immediately preceding the delivery
date. Holders of Atlantes Common Stock, Atlantes Warrants and Atlantes Options
should consider the following: whether, and to what extent, the performance
targets are met will be dependent on the management of Atlantes after the
Effective Time and that the control of the business of Atlantes will rest,
ultimately, with Metromail; there will be no Contingent Shares delivered for a
Measurement Period if the number of Qualifying Records is less than 80% of the
performance target for such period; the performance targets for the years 1998
through 2001 are 12,000,000, 15,000,000, 19,500,000 and 24,000,000 Qualifying
Records, respectively, compared to the approximately 6,000,000 Qualifying
Records collected by Atlantes during 1996; the aggregate of the Contingent
Payment Amounts for all four Measurement Periods cannot exceed $12,500,000,
and such maximum is subject to reduction if the Contingent Payment Amount for
a particular Measurement Period is less than the targeted amount for such
period; the number of Contingent Shares that can be delivered to holders of

Warrants, cannot exceed the aggregate number of shares issued to such holders
at the Effective Time in respect of shares of Atlantes Common Stock, or shares
of Atlantes Common Stock and Atlantes Warrants, respectively; and there can be
no assurance that any Contingent Shares will be deliverable after the
Effective Time. See "THE MERGER AGREEMENT--Contingent Shares."

FACTORS RELATING TO INVESTMENT IN METROMAIL COMMON STOCK
 
  The following factors should be considered in evaluating an investment in
shares of Metromail Common Stock:
   
  Regulation. Adoption of additional guidelines by the Direct Marketing
Association or new guidelines applicable to Metromail's reference services and
enactment of federal or state laws or regulations affecting either Metromail's
direct marketing or reference services could have the effect of materially
increasing the cost to Metromail of collecting certain kinds of information,
precluding the use by direct marketers of information that Metromail could
lawfully collect or otherwise materially adversely affecting Metromail's
business, operating results or financial condition. See "ADDITIONAL
INFORMATION REGARDING METROMAIL--Business of Metromail--Regulation."     
 
  Absence of Long-Term Contracts; Lack of Predictability of Sales;
Fluctuations in Operating Results. Metromail's sales, particularly with
respect to its direct marketing products, are generally not derived from long-
term contracts. Therefore, Metromail must continually engage in sales efforts
and must be prepared to adjust its pricing terms to meet competition.
Metromail's net sales are affected by a number of seasonal characteristics and
other factors, including, with respect to Metromail's direct marketing
services, the timing and extent of the direct marketing activities of
Metromail's clients. These activities are influenced by general factors, such
as postal rates, paper prices and overall economic conditions, and by factors
specific to a client, such as the client's advertising budget and choice of
advertising media. Metromail's net sales can also be affected by the
availability of new or updated data. Thus, if Metromail does not update its
database as quickly as do its competitors, Metromail's net sales could be
adversely affected. The potential unpredictability of Metromail's net sales
can lead to fluctuations in quarterly and annual operating results, especially
because many expenses are incurred by Metromail ratably throughout the year.
In addition, the expenses associated with acquiring data, and the timing of
acquisitions and the costs and expenses associated therewith, might also
affect operating results.
 
  Competition. The markets in which Metromail competes are highly competitive
and fragmented. Some of Metromail's competitors have, and potential
competitors may have, materially greater financial, technical and marketing
resources than Metromail that may allow them to compete effectively with
Metromail in respect of some or all of its database marketing, direct
marketing and reference services. See "ADDITIONAL INFORMATION REGARDING
METROMAIL--Business of Metromail--Competition."
 
  Technological Changes and Software Development. Metromail's future success
is dependent on its ability to keep pace with technological improvements,
including as they affect Metromail's ability to input collected information
into its database and produce the information desired by its clients and the
costs of doing so. In addition, Metromail's future success in respect of its
marketing database software will depend upon its ability to enhance its
current products and to develop and introduce new products and services on a
timely basis that keep pace with technological developments and address the
increasingly sophisticated needs of its clients. If Metromail is unable to
keep pace with technological improvements or is unable, for technological or
other reasons, to develop and introduce new products or enhancements of
existing products in a timely and cost-effective manner in response to
changing market conditions or customer requirements, Metromail's business,
operating results or financial condition could be materially adversely
affected.
 
  Litigation. Metromail cannot predict the effects, if any, that the
litigation discussed under "ADDITIONAL INFORMATION REGARDING METROMAIL--
Business of Metromail--Legal Proceedings" may have on its business, operating
results or financial condition, although such litigation could have an adverse
effect on Metromail (including through adverse publicity) if Metromail were
not to be successful in its defense or if Metromail's insurer were to deny
coverage.
 
  Risk of Loss of Data Centers or Interruption of Telecommunications Services.
Metromail's operations are dependent on its ability to protect its data
centers in Lombard, Illinois and Lincoln, Nebraska against damage from fire,
power loss, telecommunications failure or similar event. In addition, the on-
line services provided by Metromail are dependent on telecommunications links
to the regional Bell operating companies. Metromail has
 
                                      12
<PAGE>
 
taken precautions to protect its data centers and telecommunications links
from events that could interrupt its operations. Any damage to Metromail's
data centers or any failure of Metromail's telecommunication links that causes
interruptions in Metromail's operations could have a material adverse effect
on Metromail's business, operating results or financial condition.
 
  Growth Through Acquisitions and New Products. Metromail's business strategy
includes growth through acquisitions of proprietary information and of
distribution channels and businesses complementary to Metromail's business.
Metromail has made a number of acquisitions in the past and believes that it
has been successful in integrating the acquired assets and businesses into
Metromail's operations. There can be no assurance, however, that future
acquisitions will be consummated on acceptable terms or that any acquired
assets or business will be successfully integrated into Metromail's
operations. Metromail's business strategy also includes growth through the
introduction of new products or services that leverage the information
contained in Metromail's database. There can be no assurance that new products
or services introduced by Metromail will achieve acceptance.

  Shares of Atlantes Common Stock represented by proxies which are marked
"abstain" will be counted as shares present for purposes of determining the
presence of a quorum on all matters, as will shares that are represented by
proxies that are executed by any broker, fiduciary or other nominee on behalf
of the beneficial owner(s) thereof regardless of whether authority to vote is
withheld by such broker, fiduciary or nominee on one or more matters.

it is expected that such meeting will be adjourned or postponed to allow for
the solicitation of additional proxies.
 
                                      13
<PAGE>
 
PROXIES
 
  All shares of Atlantes Common Stock which are represented by properly
executed proxies received by Atlantes prior to or at the Atlantes Special
Meeting and not revoked will be voted at the Atlantes Special Meeting in
accordance with the instructions indicated in such proxies. If no instructions
are indicated, such shares will be voted FOR approval of the Merger Agreement
and FOR approval of the Parachute Proposal. The Atlantes Board does not know
of any other matters to be brought before the Atlantes Special Meeting. If any
other matters are properly presented at the Atlantes Special Meeting for
action, the persons named in the enclosed form of proxy and acting thereunder
will have discretion to vote on such matters in accordance with their best
judgment.
 
  An Atlantes shareholder who has given a proxy may revoke it at any time
prior to its exercise by filing a written notice of such revocation with the
Secretary of Atlantes at or prior to the Atlantes Special Meeting, by
delivering to Atlantes a duly executed later dated proxy or by attending the
Atlantes Special Meeting and voting in person (although attendance at the
Atlantes Special Meeting will not in and of itself constitute a revocation of
a proxy). All written notices of revocation and other communications with
respect to revocation of proxies in connection with the Atlantes Special
Meeting should be addressed to Atlantes Corporation, 90 Madison Street,
Denver, Colorado 80206, Attention: Kenneth W. Edwards, Jr., Secretary.
 
SOLICITATION OF PROXIES
 
  Proxies are being solicited hereby on behalf of the Atlantes Board. All
expenses incurred in connection with the solicitation of proxies by and on
behalf of the Atlantes Board will be borne by Atlantes. In addition to the use
of the mails, proxies may be solicited personally or by telephone by
directors, officers and employees of Atlantes who will not be additionally
compensated therefor, but may be reimbursed for their out-of-pocket expenses
incurred in connection with such solicitation.
 
REQUIRED VOTE
 
  Approval of the Merger Agreement will require the affirmative vote of the
holders of two-thirds of the shares of Atlantes Common Stock outstanding on
the Atlantes Record Date. Approval of the Parachute Proposal will require the
affirmative vote of the holders of at least 75% of the shares of Atlantes
Common Stock outstanding immediately prior to the Effective Time, disregarding
the shares held by the Chairman of Atlantes. If the holders of all outstanding
Atlantes Warrants were to exercise such warrants prior to the Effective Time
(assuming no holders of Atlantes Stock Options were to exercise such options),
the holders of approximately 91% of the shares of Atlantes Common Stock
outstanding on the Atlantes Record Date (disregarding shares held by the
Chairman) would be required to approve the Parachute Proposal.
 
  Abstentions and votes which are not cast because the nominee-broker either
lacks or fails to exercise discretionary authority with respect to the
proposal to approve the Merger Agreement or the Parachute Proposal will have
the effect of votes against such proposal.
 
  The holders of 193,760 shares of Atlantes Common Stock outstanding at the
close of business on the Atlantes Record Date (approximately 40.6% of the
shares of Atlantes Common Stock then outstanding) have signed agreements
obligating them to vote in favor of the Merger Agreement and against certain
other action. See "VOTING AGREEMENTS."
 
  At the close of business on the Atlantes Record Date, directors and
executive officers of Atlantes were the record owners of an aggregate of
153,321 (approximately 32.2%) of the shares of Atlantes Common Stock then
outstanding. Such shares do not include the shares subject to the voting
agreements described above. Atlantes expects that all such shares will be
voted in favor of approval of the Merger Agreement and the Parachute Proposal.
 
DISSENTERS' RIGHTS
 
  Holders of Atlantes Common Stock have the right to dissent from the Merger
and to receive payment of the fair value of their shares upon full compliance
with Article 113 of the CBCA. A copy of Article 113 of the
 
                                      14

CBCA is attached hereto as Annex B. If holders of more than 1% of the shares
of Atlantes Common Stock outstanding immediately prior to the Effective Time
properly exercise dissenters' rights, Metromail will have the right to decline
to consummate the Merger. See "DISSENTERS' RIGHTS" and "THE MERGER AGREEMENT--

Merger."
 
BACKGROUND OF THE MERGER
 
  From time to time over the last twelve months, Atlantes received unsolicited
contacts from companies, including Metromail, indicating an interest in
acquiring or merging with Atlantes. On November 22, 1996, members of the
Atlantes Board discussed the various inquiries that had been received and the
short and long range prospects for Atlantes. The Atlantes Board decided at
that time to hire an investment advisor to assist Atlantes in its
consideration of various opportunities for sale of Atlantes.
 
                                      16
<PAGE>
 
  On December 10, 1996, the Atlantes Board retained The Wallach Company to
serve as its financial advisor in connection the possible sale of Atlantes
and, if requested, to provide a fairness opinion with respect to any proposal
received. At a January 31, 1997 meeting, after a presentation of strategic
buyer candidates by management and The Wallach Company, the Atlantes Board
agreed that the process of exploring a sale of Atlantes should target those
companies believed most likely to be interested in a strategic combination
with Atlantes, such parties to include those companies which had made prior
indications of interest and those additional companies determined after
consultation with The Wallach Company, management and the directors.
 
  Following the January 31, 1997 meeting, management and The Wallach Company
prepared information materials describing Atlantes. Beginning February 4,
1997, The Wallach Company solicited indications of interest from nine
companies which were believed to have the strongest strategic opportunities
with Atlantes. Upon executing a confidentiality agreement, the contacted
parties were forwarded the information materials on Atlantes. In connection
with the process, the participants were given the opportunity to conduct a due
diligence review of Atlantes and received a set of procedures for the
submission of definitive proposals. The procedures set forth delivery
instructions, requested best offers, required that proposals remain in effect
until April 4, 1997, stated that all proposals would be reviewed by the
Atlantes Board, and required that all proposals be submitted by March 20,
1997.
 
  As part of its due diligence review, each party was invited to attend a
three hour management presentation, further describing the business and
prospects for Atlantes. These presentations were given during the first part
of March.
 
  By March 20, 1997, The Wallach Company, as representative of Atlantes, had
received responses from five entities, including Metromail, concerning their
interest in the acquisition of the outstanding common stock of Atlantes. On
March 21, 1997, The Wallach Company presented these responses to certain
members of management and the Atlantes Board . The Atlantes Board determined
at that meeting that, based on the economic value offered at closing, the
potential of future consideration pursuant to contingent payments, the lack of
contingencies relative to certain Atlantes' contracts and the alternative of
either stock or cash consideration, the proposal submitted by Metromail was
deemed to provide the best alternative for the Atlantes' shareholders. The
Atlantes Board also determined that the management team of Atlantes should
conduct a due diligence review of Metromail.
 
  Accordingly, on April 1, 1997, the management team of Atlantes visited
Metromail for a presentation by the management of Metromail on the business
operations and prospects of Metromail. At that meeting, certain terms of the
Metromail proposal were clarified and negotiated with Metromail modifying its
indication of interest in a letter dated April 3, 1997. On April 4, 1997, the
Atlantes Board voted to approve proceeding with negotiation of a definitive
agreement with Metromail consistent with the terms of Metromail's modified
indication of interest. On April 7, 1997, Atlantes signed a no-shop agreement
with Metromail prohibiting the Company from holding any further merger or
transaction discussions with any other party for 60 days in order to allow
Metromail to complete its due diligence and to begin discussions leading to a
definitive agreement for the possible acquisition of Atlantes by Metromail.
The no-shop agreement was a condition to Metromail's continued interest in
acquiring Atlantes.
 
  After the no-shop agreement was executed, Metromail began further due
diligence reviews of Atlantes. The parties also commenced negotiation and
drafting of the definitive agreements with the negotiations and reviews
continuing through May 17, 1997. On May 17, 1997, the Merger Agreement and
Employment Agreements were considered and approved by the Atlantes Board. In
addition, The Wallach Company delivered its oral opinion to the Atlantes Board
on May 17, 1997, which was subsequently confirmed in the Fairness Opinion,
that the consideration to be received by the shareholders of Atlantes pursuant
to the Merger Agreement is fair, from a financial point of view, to such
holders. The Merger Agreement was signed on May 17, 1997.
 
METROMAIL'S REASONS FOR THE MERGER
 
  Metromail's strategy includes developing more sources of self-reported data,
as compared to the traditional compiled and proprietary data. Self-reported
data allows Metromail's clients to target their customers based on
 
                                      17
<PAGE>
 
lifestyles and interests supplied by the ultimate consumer. Additionally,
self-reported data allows consumers to determine whether they want to allow
the data they provide to be used for direct marketing purposes. Although
Metromail currently has access to the Atlantes database through a sublicense
agreement with Experian, Inc. ("Experian"), which has an exclusive contract
with Atlantes to market Atlantes' database, Metromail believes its acquisition
of Atlantes will significantly increase the size and content of its self-
reported consumer lifestyle database by focusing the form and content of
Atlantes' questionnaires to complement Metromail's existing database and by
providing greater capital investment in the business.
 
ATLANTES' REASONS FOR THE MERGER; RECOMMENDATION OF ITS BOARD OF DIRECTORS
 
  The Atlantes Board has unanimously determined that the Merger is fair and in
the best interests of Atlantes and its shareholders and has unanimously
adopted the Merger Agreement. Accordingly, the Atlantes Board recommends that
the shareholders of Atlantes vote in favor of approval of the Merger Agreement
at the Atlantes Special Meeting.
 
  In reaching its decision to adopt the Merger Agreement, the Atlantes Board
considered a number of factors, including the following:
 
    (i) Information regarding the historical and current financial condition,
  results of operations, business and prospects for Atlantes.
 
    (ii) Information regarding the projected future earnings of Atlantes.
 
    (iii) The strategic and financial alternatives available to Atlantes,
  including remaining a separate company and the sale of Atlantes as a whole.
 
    (iv) The future capital required for Atlantes to grow as a separate
  company.
 
    (v) The fact that, because Atlantes competes against companies which are
  much larger and benefit from greater capitalization, an affiliation with a
  larger, recognized company may provide opportunities for greater economic
  growth for Atlantes.
     
    (vi) While the ability to generate additional names for its database
  should continue, Atlantes currently depends on an outside party for the
  sale of its database. Metromail is currently a reseller of the information
  in Atlantes' database pursuant to a contract with the outside party. A
  combination with Metromail would increase the incentive for Metromail to
  resell Atlantes' data, thereby increasing Atlantes' revenue.     
 
    (vii) The lack of a public market for the shares of Atlantes Common
  Stock.
 
    (viii) The terms and conditions of the Merger Agreement as reviewed and
  discussed with Atlantes' management, financial advisors and legal counsel.
  The Atlantes Board gave consideration to, among other things, the amount
  and form of consideration offered to Atlantes' shareholders both initially
  and potentially through the contingent payment provisions, the structure of
  the proposed business combination, and the provisions related to various
  contracts entered into by Atlantes.
 
    (ix) The offers made by other interested parties.
 
    (x) The financial condition, stock valuation and future prospects of
  Metromail, including the ability of Metromail to complete the Merger in a
  timely manner.
 
    (xi) The absence of any term or condition which, in the opinion of the
  Atlantes Board, could materially impede or impair the consummation of the
  Merger.
 
    (xii) The Employment Agreements entered into by three of Atlantes'
  management team.
 
    (xiii) The financial presentation of The Wallach Company and the opinion
  of The Wallach Company, delivered to the Atlantes Board that the
  consideration to be received by the shareholders of Atlantes pursuant to
  the Merger Agreement is fair, from a financial point of view, to such
  holders.
   
  In the course of its discussions, the Atlantes Board extensively discussed
the price that would be obtained by the Atlantes shareholders, the nature of
the proposed merger consideration, the intended tax-free nature of the Merger,
the liquidity of the Metromail Common Stock and Metromail's strategic fit with
Atlantes. However, the Atlantes Board did not assign relative weights to the
foregoing factors or determine that any factor was of more importance than
other factors. Rather, the Atlantes Board viewed its position and
recommendations as being based on the totality of the information presented to
and considered by it. Accordingly, all of the foregoing factors impacted the
Atlantes Board's decision to some extent.

  THE ATLANTES BOARD UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF ATLANTES
VOTE IN FAVOR OF APPROVAL OF THE MERGER AGREEMENT AND THE PARACHUTE PROPOSAL
AT THE ATLANTES SPECIAL MEETING.
 
OPINION OF ATLANTES' FINANCIAL ADVISOR
 
  The Wallach Company was engaged by Atlantes pursuant to an engagement letter
dated December 10, 1996 (the "Engagement Letter") to act as its financial
advisor in connection with a potential sale of Atlantes and to render an
opinion as to the fairness, from a financial point of view, of the
consideration to be received by the holders of Atlantes Common Stock in any
proposed business combination or similar transaction. The Wallach Company, an
investment banking firm located in Denver, Colorado, is regularly engaged in
the sale of businesses and in the valuation of businesses and their securities
in connection with mergers and acquisitions. The Wallach Company has not
performed investment banking services for Atlantes or Metromail in the past.
 
  In this role, The Wallach Company acted as financial advisor to Atlantes in
connection with the Merger and delivered the Fairness Opinion to the Atlantes
Board to the effect that, based upon and subject to the various considerations
set forth therein, as of the date thereof, the consideration to be received in
the Merger by the holders of Atlantes Common Stock is fair to such holders
from a financial point of view. No limitations were imposed by the Atlantes
Board upon The Wallach Company with respect to the investigations made or the
procedures followed by it in rendering the Fairness Opinion.
 
  THE FULL TEXT OF THE FAIRNESS OPINION, WHICH SETS FORTH THE ASSUMPTIONS
MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED
HERETO AS ANNEX C AND SHOULD BE READ CAREFULLY IN ITS ENTIRETY. THE SUMMARY OF
THE FAIRNESS OPINION SET FORTH IN THIS PROXY STATEMENT/PROSPECTUS IS QUALIFIED
IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF THE FAIRNESS OPINION. THE
FAIRNESS OPINION DOES NOT CONSTITUTE A RECOMMENDATION TO ANY HOLDER OF
ATLANTES COMMON STOCK AS TO HOW SUCH HOLDER SHOULD VOTE ON THE MERGER
AGREEMENT OR ANY RECOMMENDATION WHATSOEVER.
 
  Prior to the time that The Wallach Company delivered the Fairness Opinion,
The Wallach Company presented its analysis and provided a verbal opinion to
the Atlantes Board to the effect that, based upon and subject to the various
considerations set forth in the written Fairness Opinion, the consideration to
be received in the Merger by the holders of Atlantes Common Stock (consisting
of consideration to be received at the Effective Time and contingent payments)
is fair to such holders from a financial point of view. In arriving at the
Fairness Opinion, The Wallach Company reviewed (i) certain business and
financial information relating to Atlantes, which is a privately held company,
(ii) certain publicly available business and financial information relating to
Metromail, (iii) summary financial forecasts for Atlantes for the years ending
December 31, 1997 and 1998, (iv) certain financial and stock market data for
publicly held companies that operate in similar industries to Atlantes, (v)
the responses made by the other companies that considered the acquisition of
Atlantes and (vi) such other information as The Wallach Company deemed
necessary or appropriate. In addition, The Wallach Company met with the
management of Atlantes to discuss the past and current business operations,
financial conditions and prospects of Atlantes. The Wallach Company also had
discussions with certain members of Metromail's management regarding the past
and current business operations, financial condition and prospects of
Metromail.
 
  In rendering the Fairness Opinion, The Wallach Company assumed and relied
upon the accuracy and completeness of all information supplied or otherwise
made available to it by Atlantes and Metromail and did not independently
verify nor assume any responsibility for independently verifying any of such
information. The Fairness Opinion was based on general economic, market,
monetary and other conditions as they existed and could be evaluated on, and
the information made available to The Wallach Company as of, the date of such
opinion. The Wallach Company expressed no opinion as to the likely trading
range of the Metromail Common Stock prior to or following the consummation of
the Merger, which may vary depending on, among other factors, changes in
interest rates, dividend rates, market conditions, general economic conditions
and other factors that generally influence the price of securities.

  In rendering the Fairness Opinion, The Wallach Company considered the
prospects for value, liquidity and growth for Atlantes if it remained
independent. In addition, The Wallach Company attempted to find comparable
public companies, conduct discounted cash flow analysis, and discover other
merger and acquisitions of companies similar to Atlantes. In all situations,
The Wallach Company determined that, due to the relatively small size, minimal
earnings, limited capitalization and limited history of Atlantes, it was
improper to use these analytical approaches as the basis of rendering the
Fairness Opinion. Rather, The Wallach Company relied on the responses that it
received from the five parties that responded to The Wallach Company's
solicitations, expressing interest in acquiring Atlantes. Based on the
informational materials presented to prospective buyers, the opportunity for
each party to conduct due diligence prior to submitting a bid, the number of
knowledgeable parties contacted with regards to this acquisition opportunity
and the specific instructions concerning the submission of definitive
proposals, The Wallach Company concluded that the Metromail offer was fair,
from a financial point of view, to the Atlantes shareholders.
 
  Pursuant to the terms of the Engagement Letter, Atlantes has agreed to pay
The Wallach Company, for advisory services and the issuance of the Fairness
Opinion, a fee of $280,000 at closing of the Merger plus additional fees which
may be paid in the event the Contingent Payment Amounts are received by the
Record Holders pursuant to the Merger Agreement. In the event that the maximum
Contingent Payment Amounts are received by the Record Holders, The Wallach
Company will be entitled to additional payments totaling $280,000. Payment of
the fee at closing plus future fees will be paid by Metromail. Atlantes also
agreed to reimburse The Wallach Company for the expenses reasonably incurred
by The Wallach Company in connection with its engagement and to indemnify The
Wallach Company and its officers, directors, agents and controlling persons
against certain expenses, losses, claims, damages or liabilities incurred in
connection with its services.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  In considering the recommendation of the Atlantes Board with respect to
approval of the Merger Agreement, Atlantes shareholders should be aware that
certain members of the Atlantes Board and executive officers of Atlantes have
interests in the Merger in addition to their interests as shareholders of
Atlantes.
 
  Employment Agreements. In connection with the execution of the Merger
Agreement, Mr. Detmer, President of Atlantes and a member of the Atlantes
Board, Mr. Anderson, Vice President--Operations of Atlantes, and Mr. O'Neil,
Vice President--Client Services of Atlantes, have executed employment
agreements with Metromail which will replace existing agreements each of such
employees has with Atlantes. These Employment Agreements take effect at the
Effective Time.
 
  Mr. Detmer's employment agreement (the "Detmer Employment Agreement")
provides for a term ending on December 31, 2001. Under his employment
agreement, Mr. Detmer will serve as President of Atlantes at an annual base
salary of no less than $138,000 per year. For the period ending December 31,
1997, Mr. Detmer's bonus and employee benefits will be determined in
accordance with the existing Atlantes's benefit plans. Beginning January 1,
1998, Mr. Detmer will be entitled to earn an annual bonus determined in
accordance with the Metromail Variable Pay Plan for appointed officers, to
receive certain perquisites and to participate in employee benefit plans
available generally to Metromail employees. During the term of the employment
agreement, Mr. Detmer will also be eligible to participate in Metromail stock
option plans in a manner consistent with participation by other executives
holding comparable positions within Metromail.
 
  In the event of early termination of employment by Metromail other than for
Cause (as defined in the Detmer Employment Agreement) or death, Metromail
would continue to pay Mr. Detmer his current salary until the date of his
termination and would pay Mr. Detmer a lump sum severance of up to one year's
salary (subject to pro-rata reduction based upon the number of months of
advance notice received for such termination (reduced to zero if 12 months
notice)) and a proportionate share of any accrued and unpaid bonus or Variable
Pay. The Detmer Employment Agreement provides for a noncompete period until
the earlier of (i) December 31, 2003, or (ii) two years following the
termination of Mr. Detmer's employment if, during the term of the agreement,
 
                                      20
<PAGE>
 
Metromail terminates his employment other than for Cause or if Mr. Detmer
terminates his employment following a Termination Event (as defined below).
 
  Mr. Anderson's employment agreement (the "Anderson Employment Agreement")
provides for a term ending on December 31, 1999. Under his employment
agreement, Mr. Anderson will serve as Vice President, Operations of Atlantes
at an annual base salary of no less than $126,000 per year. For the period
ending December 31, 1997, Mr. Anderson's bonus and employee benefits will be
determined in accordance with the existing Atlantes's benefit plans. Beginning
January 1, 1998, Mr. Anderson will be entitled to earn an annual bonus
determined in accordance with the Metromail Variable Pay Plan for directors
and managers, to receive certain perquisites and to participate in employee
benefit plans available generally to Metromail employees. During the term of
the employment agreement, Mr. Anderson will also be eligible to participate in
Metromail stock option plans in a manner consistent with participation by
other executives holding comparable positions within Metromail.
 
  In the event of early termination of employment by Metromail other than for
Cause (as defined in the Anderson Employment Agreement) or death, Metromail
would continue to pay Mr. Anderson his current salary until the date of his
termination and would pay Mr. Anderson a lump sum severance of up to one
year's salary (subject to pro-rata reduction based upon the number of months
of advance notice received for such termination (reduced to zero if 12 months
notice)) and a proportionate share of any accrued and unpaid bonus or Variable
Pay. The Anderson Employment Agreement provides for a noncompete period until
the earlier of (i) December 31, 2001, or (ii) two years following the
termination of Mr. Anderson's employment if, during the term of the agreement,
Metromail terminates his employment other than for Cause or if Mr. Anderson
terminates his employment following a Termination Event.
 
  Mr. O'Neil's employment agreement (the "O'Neil Employment Agreement")
provides for a term ending on June 30, 2000. Under his employment agreement,
Mr. O'Neil will serve as Vice President, Client Services of Atlantes at an
annual base salary of no less than $126,000 per year. For the period ending
December 31, 1997, Mr. O'Neil's bonus and employee benefits will be determined
in accordance with the existing Atlantes's benefit plans. Beginning January 1,
1998, Mr. O'Neil will be entitled to earn an annual bonus determined in
accordance with the Metromail Variable Pay Plan for directors and managers, to
receive certain perquisites and to participate in employee benefit plans
available generally to Metromail employees. During the term of the employment
agreement, Mr. O'Neil will also be eligible to participate in Metromail stock
option plans in a manner consistent with participation by other executives
holding comparable positions within Metromail.
 
  In the event of early termination of employment by Metromail other than for
Cause (as defined in the O'Neil Employment Agreement) or death, Metromail
would continue to pay Mr. O'Neil his current salary until the date of his
termination and would pay Mr. O'Neil a lump sum severance of up to one year's
salary (subject to pro-rata reduction based upon the number of months of
advance notice received for such termination (reduced to zero if 12 months
notice)) and a proportionate share of any accrued and unpaid bonus or Variable
Pay. The O'Neil Employment Agreement provides for a noncompete period until
the earlier of (i) June 30, 2002, or (ii) two years following the termination
of Mr. O'Neil's employment if, during the term of the agreement, Metromail
terminates his employment other than for Cause or if Mr. O'Neil terminates his
employment following a Termination Event.
 
  A "Termination Event" means, with respect to each of Messrs. Detmer,
Anderson and O'Neil, subject to certain exceptions, (i) a Change in Control
Termination Event (as defined in the Employment Agreements); (ii) the
relocation of such officer to a location outside the greater Denver, Colorado
area without his consent; (iii) such officer's demotion from his position in
Atlantes without his prior consent; or (iv) any reduction in the overall
benefits made available to such officer without his prior consent.

CERTAIN MATERIAL FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a summary description of certain material federal income
tax consequences of the Merger. The discussion does not address all aspects of
federal taxation that may be relevant to holders of Atlantes Common Stock,
Atlantes Warrants or Atlantes Stock Options, and it might not be applicable to
any such holder who, for United States federal income tax purposes, is a
nonresident alien individual, foreign corporation, foreign partnership,
foreign trust or foreign estate, or who acquired Atlantes Common Stock or an
Atlantes Warrant pursuant to the exercise of employee stock options or
otherwise as compensation. This summary is not a complete description of all
the consequences of the Merger. Moreover, the individual circumstances of a
holder of Atlantes Common Stock, Atlantes Warrant or Atlantes Stock Option may
affect the tax consequences of the Merger to such holder.
 
 
                                      22
<PAGE>
 
  THE DISCUSSION IS BASED ON CURRENTLY EXISTING PROVISIONS OF THE INTERNAL
REVENUE CODE OF 1986, AS AMENDED (THE "CODE"), EXISTING AND PROPOSED TREASURY
REGULATIONS THEREUNDER AND CURRENT ADMINISTRATIVE RULINGS AND COURT DECISIONS,
ALL OF WHICH ARE SUBJECT TO CHANGE AND ANY SUCH CHANGE COULD AFFECT THE
CONTINUING VALIDITY OF THIS DISCUSSION. THE DISCUSSION SET FORTH BELOW DOES NOT
ADDRESS THE STATE, LOCAL OR FOREIGN TAX ASPECTS OF THE MERGER. HOLDERS OF
ATLANTES COMMON STOCK, ATLANTES WARRANTS OR ATLANTES STOCK OPTIONS ARE
THEREFORE URGED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE SPECIFIC
TAX CONSEQUENCES OF THE MERGER TO SUCH HOLDERS, INCLUDING THE APPLICATION AND
EFFECT OF STATE, LOCAL AND FOREIGN TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES
IN FEDERAL LAWS OR OTHER TAX LAWS.
 
 Atlantes Common Stock
 
  General. It is a condition to Atlantes' obligation to consummate the Merger
that Atlantes receive an opinion from its counsel, Holland & Hart LLP, and it
is a condition to Metromail's obligation to consummate the Merger that
Metromail receive an opinion from its counsel, Sidley & Austin, in each case
substantially to the effect that for federal income tax purposes:
 
    (i) The Merger will constitute a "reorganization" within the meaning of
  Section 368(a) of the Code, and Atlantes, Mergerco and Metromail will each
  be a party to such reorganization within the meaning of Section 368(b) of
  the Code;
 
    (ii) No gain or loss will be recognized by Metromail or Atlantes as a
  result of the Merger;
 
    (iii) No income, gain or loss will be recognized by the shareholders of
  Atlantes upon the exchange of their Atlantes Common Stock for shares of
  Metromail Common Stock or cash (or a combination thereof) pursuant to the
  Merger, except that gain realized on such exchange will be recognized to
  the extent of cash received (excluding cash, if any, received in lieu of
  fractional shares of Metromail Common Stock), gain or loss will be
  recognized with respect to cash, if any, received in lieu of fractional
  shares of Metromail Common Stock and income will be recognized to the
  extent of any amount treated as interest;
 
    (iv) The aggregate tax basis of the shares of Metromail Common Stock
  received in exchange for Atlantes Common Stock pursuant to the Merger
  (including fractional shares of Metromail Common Stock for which cash is
  received) will be the same as the aggregate tax basis of the Atlantes
  Common Stock exchanged therefor, reduced by the amount of cash received in
  such exchange (excluding cash, if any, received in lieu of fractional
  shares of Metromail Common Stock), increased by any gain recognized by
  reason of the receipt of such cash in such exchange, and increased by any
  amount treated as interest;
 
    (v) Except to the extent of Metromail Common Stock treated as interest,
  the holding period for shares of Metromail Common Stock received in
  exchange for Atlantes Common Stock pursuant to the Merger will include the
  holding period of the Atlantes Common Stock exchanged therefor, provided
  such Atlantes Common Stock was held as a capital asset by the shareholder
  at the Effective Time; and
     
    (vi) A shareholder of Atlantes who receives cash in lieu of a fractional
  share of Metromail Common Stock will recognize gain or loss equal to the
  difference, if any, between such shareholder's tax basis in such fractional
  share (as described in clause (iv) above) and the amount of cash received.
      
  An opinion of counsel is not binding on the Internal Revenue Service or the
courts.
 
  In rendering such opinions, Holland & Hart LLP and Sidley & Austin may make
certain assumptions, and may receive and rely upon representations (which have
not been independently verified by counsel) contained in certificates of
Atlantes, Metromail, certain shareholders of Atlantes, and others. If any such
assumption or representation is inaccurate, such inaccuracy might jeopardize
the validity of the opinions rendered by counsel.
 
  Computation of Gain. Cash received pursuant to an election to convert shares
of Atlantes Common Stock into cash rather than Metromail Common Stock will be
taxable only to the extent of the overall gain realized by
 
                                       23
<PAGE>
 
   
the shareholder in the Merger (with the realized gain in general equal to the
excess of such cash plus the value of Metromail Common Stock received or to be
received in the Merger, over the shareholder's tax basis in the Atlantes
Common Stock converted in the Merger). See clause (iii) under "General" above.
Because Metromail Common Stock might be received as Contingent Shares, the
extent of a shareholder's realized gain, and hence the extent to which such
cash will be taxable, might not be certain as of the time the cash is
received. Although not clear, one approach might be for a shareholder to
compute realized gain for this purpose by assuming that no Contingent Shares
will be received. Another approach might be to compute realized gain for this
purpose by assuming Contingent Shares having the maximum possible value will
be received. In either case, adjustments to income and basis would be required
upon an installment of Contingent Shares being received or upon a
determination that such installment will not be received, depending on the
assumption originally made. Other possible tax rules might apply. SHAREHOLDERS
OF ATLANTES WHO ELECT TO CONVERT ONE OR MORE SHARES OF ATLANTES COMMON STOCK
INTO CASH RATHER THAN METROMAIL COMMON STOCK ARE STRONGLY URGED TO CONSULT
THEIR OWN TAX ADVISORS WITH RESPECT TO THE FEDERAL, STATE, LOCAL, FOREIGN AND
OTHER TAX CONSEQUENCES OF SUCH AN ELECTION.     
   
  Basis Considerations. On the date of delivery to an Atlantes shareholder of
shares of Metromail Common Stock (upon the effectiveness of the Merger or as
Contingent Shares) or on the date of a determination that a scheduled
installment of Contingent Shares will not be delivered (each such time, an
"Allocation Date"), a portion of an Atlantes shareholder's tax basis in
Metromail Common Stock determined as described in clause (iv) under "General"
above but disregarding amounts treated as interest (hereinafter, "Aggregate
Metromail Tax Basis") must be temporarily allocated to the Metromail Common
Stock delivered or previously delivered, including fractional shares of
Metromail Common Stock for which cash is received, but excluding any portion
of delivered or previously delivered Metromail Common Stock treated as imputed
interest under the rules described below (collectively, the "Total Delivered
Shares") with the remainder of such shareholder's tax basis being "suspended"
until the next Allocation Date.     
   
  The portion of a shareholder's Aggregate Metromail Tax Basis allocated on
any Allocation Date to the Total Delivered Shares equals (a) such
shareholder's Aggregate Metromail Tax Basis (less the tax basis of any Total
Delivered Shares previously disposed of), multiplied by (b) a fraction, the
numerator of which is the number of Total Delivered Shares and the denominator
of which is the sum of the number of the Total Delivered Shares and the
maximum number of Contingent Shares which could be received by such
shareholder in the future, excluding any Total Delivered Shares previously
disposed of and also excluding any portion of such future Contingent Shares
which would be treated as imputed interest under the rules described below.
The amount allocated on an Allocation Date should be allocated pro rata among
the Total Delivered Shares held by such shareholder on an Allocation Date. The
portion of any Contingent Share received as imputed interest will have a tax
basis equal to its fair market value on the date such portion is treated as
having been received and, as described below, will have a holding period
beginning on such date.     
   
  The Merger Agreement provides that the maximum aggregate number of
Contingent Shares to which all holders of Atlantes Common Stock will be
entitled may not exceed the aggregate number of shares of Metromail Common
Stock received by such holders upon the effectiveness of the Merger
(hereinafter referred to as "Fixed Shares"). Nevertheless, the number of
Contingent Shares received by any particular holder of Atlantes Common Stock
relative to the number of Fixed Shares received by that holder might vary
significantly based on a number of factors, including the per share price of
Metromail Common Stock used to determine the number of Contingent Shares to be
delivered on a Contingent Share Delivery Date (as defined herein), the number
of shares of Atlantes Common Stock with respect to which such holder elects to
receive cash, and the extent to which other holders of Atlantes Common Stock
or holders of Atlantes Warrants elect to receive cash. In the absence of more
precise information, a shareholder should probably apply the foregoing rules
by assuming that (consistent with the overall limitation described above) such
holder will receive a number of Contingent Shares equal to the number of Fixed
Shares such holder would have received had the holder made no election to
convert shares of Atlantes Common Stock into cash.     
   
  For purposes of the foregoing rules, it is unclear how a shareholder should
determine the portion of future Contingent Shares which would be treated as
imputed interest under the rules described below. Because of the practical
difficulty in making such a determination, in the absence of relevant
information a shareholder might choose to apply the fraction set forth in the
second preceeding paragraph by assuming that no portion of future     
 
                                      24
<PAGE>
 
   
Contingent Shares will be treated as imputed interest. Shareholders should
consult their own tax advisors in this regard.     
   
  AS A RESULT OF THESE BASIS RULES, AN ATLANTES SHAREHOLDER THAT SELLS ALL OR A
PORTION OF SUCH SHAREHOLDER'S FIXED SHARES OR PREVIOUSLY DELIVERED CONTINGENT
SHARES PRIOR TO THE TIME OF DELIVERY OF ALL CONTINGENT SHARES (OR THE
DETERMINATION THAT NO ADDITIONAL CONTINGENT SHARES WILL BE DELIVERED) WILL
GENERALLY RECOGNIZE SIGNIFICANTLY MORE GAIN (OR SIGNIFICANTLY LESS LOSS) ON
SUCH SALE THAN WOULD BE THE CASE IF SUCH SHAREHOLDER SOLD SUCH FIXED SHARES OR
PREVIOUSLY DELIVERED CONTINGENT SHARES AT THE SAME PRICE AFTER SUCH TIME.
SHAREHOLDERS ARE STRONGLY URGED TO CONSULT SUCH SHAREHOLDER'S OWN TAX ADVISOR
REGARDING THESE BASIS RULES.     
   
  Imputed Interest Rules; Related Holding Period Consequences. A portion of the
value of the Contingent Shares (if any) received by an Atlantes shareholder
(including a fractional Contingent Share for which cash is received) will be
treated as imputed interest under Section 483 of the Code and will be taxable
to the shareholder in the taxable year of receipt. The amount treated as
interest cannot be determined until the year in which the Contingent Shares are
received. The method for determining the amount of imputed interest is
demonstrated by Treas. Reg. 1.483-4. The amount of imputed interest would be
equal to the excess of the fair market value of the Contingent Shares received
(determined at the time of receipt) over the present value of such fair market
value as of the Effective Time, discounted at the applicable federal rate in
effect for imputed interest at the Effective Time. In general, imputed interest
payments aggregating $600 or more to a non-corporate recipient are required to
be reported to the Internal Revenue Service and the recipient thereof. As
described above, the portion of any Contingent Share received as imputed
interest will have a tax basis equal to its fair market value on the date such
portion is treated as having been received.     
   
  An Atlantes shareholder's holding period for the Contingent Shares will be
split with respect to each such share (or fractional share). An Atlantes
shareholder's holding period for a portion of each Contingent Share will
include the holding period for the Atlantes Common Stock surrendered in the
Merger (provided such shares of Atlantes Common Stock are held as capital
assets by the shareholder at the Effective Time) and an Atlantes shareholder's
holding period for the remaining portion of each Contingent Share will commence
on the date on which the Contingent Share is received. This splitting of the
holding period for each Contingent Share is determined based on the portion of
the value of each Contingent Share which is taxed as interest income pursuant
to the rules summarized in the preceding paragraph in comparison to the total
value of the Contingent Share on the date of receipt of such share, with that
portion of each such share which is taxed as interest income receiving the new
holding period.     
       
 Atlantes Warrants
 
  A holder of an Atlantes Warrant who exercises such Atlantes Warrant prior to
the Merger will, with respect to Atlantes Common Stock received upon such
exercise and converted into Metromail Common Stock or cash (or a combination
thereof) pursuant to the Merger, have the federal income tax consequences
summarized above under "--Atlantes Common Stock."
   
  A holder of Atlantes Warrants may choose not to exercise such Warrants and
may, instead exchange the Warrants for Metromail Common Stock or cash (or a
combination thereof). The exchange of Atlantes Warrants for Metromail Common
Stock or cash (or a combination thereof) will be a taxable transaction for
federal income tax purposes. In general, and subject to special rules, a holder
of Atlantes Warrants will recognize gain or loss based on the difference
between the amount of cash and the fair market value of Metromail Common Stock
received (whether received as Fixed Shares or Contingent Shares, but net of
amounts treated as imputed interest as described above) and the holder's tax
basis in the Atlantes Warrant. A portion of each installment of Contingent
Shares will, in general and subject to special rules, be treated for federal
income tax purposes as interest income under rules similar to those described
above under "--Atlantes Common Stock--Imputed Interest Rules; Related Holding
Period Consequences." Holders of Atlantes Warrants should consult their own tax
advisors as to the application of those rules, as well as the application of
the installment sale provisions of     
 
                                       25
<PAGE>
 
   
the Code and the Treasury Regulations thereunder (or an election out of such
provisions), to the exchange of Atlantes Warrants for Metromail Common Stock or
cash (or a combination thereof) pursuant to the Merger.     
 
 Atlantes Options
   
  Holders of Atlantes Stock Options will recognize ordinary compensation income
as a result of the receipt of Metromail Common Stock or cash (or a combination
thereof) in exchange for Atlantes Stock Options in the Merger. The amount
treated as compensation income will equal the amount of cash (if any) and the
fair market value of the shares of Metromail Common Stock received at the
Effective Time and the entire fair market value of the Contingent Shares, if
any, generally at the time such shares are received by an option holder. Such
amounts will be (i) subject to tax at the option holder's ordinary income tax
rate, (ii) subject to the hospital insurance portion of the tax under the
Federal Insurance Contributions Act (i.e., FICA tax) (currently 1.45%), and
(iii) depending on an option holder's individual circumstances, subject in
whole or in part to the old-age, survivors and disability portion of the FICA
tax (currently 6.2%). The amount of cash (if any) and the number of shares of
Metromail Common Stock otherwise payable to an option holder will generally be
reduced by the foregoing taxes and any other amounts Metromail is required to
withhold. An option holder will have a tax basis in the Metromail Common Stock
received in exchange for such holder's Atlantes Stock Options equal to the fair
market value of such stock on the date when it is received and the holding
period of such stock, for the purpose of determining whether a subsequent sale
thereof would result in the recognition of short-term or long-term capital gain
or loss, will generally commence on such date.     
 
 Dissenting Shareholders
 
  A shareholder of Atlantes who exercises dissenters' rights as described below
under "DISSENTERS' RIGHTS" should, in general, treat the difference between the
tax basis of the Atlantes Common Stock held by such shareholder with respect to
which such rights are exercised and the amount received through the exercise of
such rights as capital gain or loss for federal income tax purposes although,
depending on the shareholder's particular circumstances, the amount received
through the exercise of such rights might be treated for federal income tax
purposes as dividend income.
 
ANTICIPATED ACCOUNTING TREATMENT
 
  The Merger will be accounted for as a "purchase" for accounting and financial
reporting purposes in accordance with APB No. 16. For purposes of preparing
Metromail's consolidated financial statements, Metromail will establish a new
accounting basis for Atlantes's assets and liabilities based upon the fair
values thereof and Metromail's purchase price, including the direct costs of
the acquisition. A final determination of required purchase accounting
adjustments and of the fair value of the assets and liabilities of Atlantes has
not yet been made. Accordingly, the purchase accounting adjustments made in
connection with the development of the pro forma financial information
appearing elsewhere in this Proxy Statement/Prospectus are preliminary and are
subject to adjustment. After the Merger, Metromail will undertake a study to
determine the fair value of Atlantes's assets and liabilities and will make
appropriate purchase accounting adjustments upon completion of such study. For
financial reporting purposes, Metromail will consolidate the results of
Atlantes's operations with those of Metromail's operations, beginning with the
consummation of the Merger, but Metromail's financial statements for prior
periods will not be restated as a result of the Merger.
 
OPERATION OF ATLANTES AFTER THE EFFECTIVE TIME
 
  The Merger Agreement provides that the directors of Mergerco immediately
prior to the Effective Time will be the directors of Atlantes, as the Surviving
Corporation, after the Effective Time until their successors are duly elected.
The directors of Mergerco are Barton L. Faber, Chairman of Metromail, Susan L
Henricks, President and Chief Executive Officer of Metromail, and Thomas J.
Quarles, Senior Vice President, Chief Administrative Officer, General Counsel
and Secretary of Metromail.
 
  Metromail has agreed in the Merger Agreement to operate or cause the business
of Atlantes to be operated in conformity with sound business practices and to
make or cause to be made all business decisions with respect to the business of
Atlantes in good faith. It is Metromail's current intention to provide Atlantes
with a reasonable opportunity to meet the Record Flow Performance Targets (as
herein defined) for each of the measurement periods described under "THE MERGER
AGREEMENT--Contingent Shares."

RESALES OF METROMAIL COMMON STOCK
 
  The shares of Metromail Common Stock issued in the Merger will be freely
transferrable, except that shares received by any person who may be deemed to
be an "affiliate" (as used in paragraphs (c) and (d) of Rule 145, under the
Securities Act, including, without limitation, directors and certain executive
officers) of Atlantes for purposes of such Rule 145, may not be resold except
in transactions permitted by such Rule 145 or as otherwise permitted under the
Securities Act.
 
                             THE MERGER AGREEMENT
 
CONVERSION OF SHARES IN THE MERGER
 
  At the Effective Time, by virtue of the Merger and without any further
action on the part of any shareholder of Atlantes or Mergerco:
 
    (i) each share of Atlantes Common Stock held in the treasury of Atlantes
  will be canceled and no capital stock of Metromail or other consideration
  will be delivered in exchange therefor;
 
    (ii) each issued and outstanding share of capital stock of Mergerco will
  be converted into one share of Common Stock, no par value, of the Surviving
  Corporation;
 
    (iii) each share of Atlantes Common Stock issued and outstanding
  immediately prior to the Effective Time (other than shares to be canceled
  as described in subparagraph (i) above) will be converted into (a) 1.241
  shares of Metromail Common Stock, or, at the election of the holder thereof
  but subject to certain limitations, $25.99 in cash, plus (b) the right to
  receive Contingent Shares in years 1999 through 2002 depending on the
  achievement of certain performance targets in years 1998 through 2001. See
  "--Contingent Shares." Each share of Metromail Common Stock issued pursuant
  to the Merger will be accompanied by a Metromail Right, subject to the
  provisions described under "DESCRIPTION OF METROMAIL COMMON STOCK--Certain
  Charter and By-law Provisions; Metromail Rights Agreement." Cash will be
  paid in lieu of any fractional shares of Metromail Common Stock. See "--No
  Fractional Shares." The number of shares of Metromail Common Stock to be
  received by Atlantes shareholders is subject to adjustment under certain
  circumstances. See "--Adjustment of Exchange Ratio."
 
  Shares of Atlantes Common Stock converted as provided in subparagraph (iii)
of the preceding paragraph will no longer be outstanding and will
automatically be canceled and retired; and each holder of a certificate
representing any such shares of Atlantes Common Stock immediately prior to the
Effective Time will cease to have any rights with respect thereto, except the
right to receive, as hereinafter described: (i) certificates representing the
number of whole shares of Metromail Common Stock or cash into which such
shares of Atlantes Common Stock have been converted, (ii) certificates
representing Contingent Shares deliverable pursuant to the Merger Agreement,
(iii) certain dividends and other distributions and (iv) cash, without
interest, in lieu of any fractional share of Metromail Common Stock. See "--
Exchange Agent; Procedures for Exchange of Certificates."
   
  HOLDERS OF ATLANTES COMMON STOCK WHO WISH TO RECEIVE CASH IN LIEU OF THE
1.241 SHARES OF METROMAIL COMMON STOCK THAT THEY WOULD RECEIVE IN EXCHANGE FOR
EACH OF THEIR SHARES OF ATLANTES COMMON STOCK UPON CONSUMMATION OF THE MERGER
MUST RETURN THE FORM OF ELECTION THAT ACCOMPANIES THIS PROXY
STATEMENT/PROSPECTUS TO THE EXCHANGE AGENT BY 5:00 P.M., NEW YORK TIME, ON
JUNE 27, 1997. HOLDERS OF ATLANTES COMMON STOCK WHO DO NOT WISH TO RECEIVE
CASH INSTEAD OF SHARES OF METROMAIL COMMON STOCK NEED NOT RETURN SUCH FORM OF
ELECTION. SEE "--CASH ELECTION."     
 
  Notwithstanding the foregoing, shares of Atlantes Common Stock that are
outstanding immediately prior to the Effective Time and which are held by
Atlantes shareholders who do not vote in favor of the proposal to approve the
Merger Agreement and who demand properly in writing the fair value for such
shares in accordance with Article 113 of the CBCA (collectively, the
"Dissenting Shares") will not be converted into or represent the
 
                                      27
<PAGE>
 
right to receive the consideration described above. Such Atlantes shareholders
will be entitled to receive payment of the fair value of such shares of
Atlantes Common Stock held by them in accordance with the provisions of the
CBCA, except that each Dissenting Share held by Atlantes shareholders who fail
to perfect or who effectively withdraw or lose their dissenters' rights under
the CBCA will be deemed to have been converted into and to have become
exchangeable for, as of the Effective Time, the right to receive 1.241 shares
of Metromail Common Stock, plus the right to receive Contingent Shares, upon
surrender of the certificate or certificates that formerly evidenced such
shares of Atlantes Common Stock in the manner described under "--Exchange
Agent; Procedures for Exchange of Certificates and Delivery of Cash." See
"DISSENTERS' RIGHTS."
 
ATLANTES WARRANTS
 
  By virtue of the Merger, each Atlantes Warrant outstanding immediately prior
to the Effective Time will be converted into (i) 1.193 shares of Metromail
Common Stock, or, at the election of the holder but subject to certain
limitations, $24.99 in cash, plus (ii) the right to receive Contingent Shares
in years 1999 through 2002 depending on the achievement of certain performance
targets in years 1998 through 2001. It is a condition to the obligations of
Metromail that Atlantes shall have received the written acknowledgment and
consent, in form reasonably acceptable to Metromail, of each holder of an
Atlantes Warrant outstanding as of the Effective Time that at the Effective
Time the Atlantes Warrant will be converted as so provided. Holders of
Atlantes Warrants will receive a notice from Atlantes notifying them of their
rights to exercise Atlantes Warrants before the Merger and receive Atlantes
Common Stock before the Merger. A holder of Atlantes Warrants who exercises
Atlantes Warrants and receives Atlantes Common Stock and who exchanges
Atlantes Common Stock for Metromail Common Stock in accordance with the Merger
Agreement will have different tax consequences than a holder of Atlantes
Warrants who elects to exchange Atlantes Warrants directly for Metromail
Common Stock. See "THE MERGER--Certain Material Federal Income Tax
Consequences."
 
ATLANTES STOCK OPTIONS
 
  By virtue of the Merger, each Atlantes Stock Option outstanding immediately
prior to the Effective Time will be converted into (i) a specified number of
shares of Metromail Common Stock (1.193 shares for each Atlantes Stock Option
with an exercise price of $1.00 per share; 1.181 shares for each Atlantes
Stock Option with an exercise price of $1.25 per share; 1.169 shares for each
Atlantes Stock Option with an exercise price of $1.50 per share; and 1.145
shares for each Atlantes Stock Option with an exercise price of $2.00 per
share), or at the election of the holder thereof $25.99 less the applicable
exercise price of the Atlantes Stock Option in cash, plus (ii) the right to
receive Contingent Shares in years 1999 through 2002 depending on the
achievement of certain performance targets in years 1998 through 2001. It is a
condition to the obligations of Metromail that Atlantes shall have received
the written acknowledgment and consent, in form reasonably acceptable to
Metromail, of each holder of an Atlantes Stock Option outstanding as of the
Effective Time that at the Effective Time the Atlantes Stock Option will be
converted as so provided.
 
CASH ELECTION
 
  General. Each holder of Atlantes Common Stock (other than holders of
Dissenting Shares), Atlantes Warrants and Atlantes Stock Options will be
entitled to receive cash instead of the shares of Metromail Common Stock to be
delivered at the Effective Time (i.e. the right to receive cash instead of
Metromail Common Stock does not apply to Contingent Shares), subject to
certain limitations in the case of holders of Atlantes Common Stock and
Atlantes Warrants.
 
  Atlantes Common Stock. A holder of Atlantes Common Stock may elect to
receive for each share of Atlantes Common Stock $25.99 in cash instead of
1.241 shares of Metromail Common Stock. The maximum number of shares of
Atlantes Common Stock for which a cash election can be made (assuming there
are no Dissenting Shares) will be the lesser of (i) 15% of the number of
shares of Atlantes Common Stock outstanding immediately prior to the Effective
Time and (ii) such number as will be determined by Metromail at the Effective
Time such that the amount of cash paid in respect of Atlantes Common Stock
does not exceed 15% of the sum of (x) the amount of cash paid in respect of
Atlantes Common Stock and (y) the market value as of the Effective Date of
Metromail Common Stock delivered at the Effective Time to holders of Atlantes
Common Stock. If there are
 
                                      28
<PAGE>
 
Dissenting Shares, the maximum number of shares of Atlantes Common Stock for
which a cash election can be made will be less than the number derived from
the previous sentence. If cash elections are received for a number of shares
of Atlantes Common Stock which exceeds the maximum number of shares for which
a cash election is permitted, the Exchange Agent (as defined below) will
determine by lot (or by such other method as is deemed reasonable by Metromail
and Atlantes) which of the shares of Atlantes Common Stock for which a cash
election was made will be converted into cash.
 
  Atlantes Warrants. A holder of an Atlantes Warrant may elect to receive for
each Atlantes Warrant $24.99 in cash instead of 1.193 shares of Metromail
Common Stock. The maximum number of Atlantes Warrants for which a cash
election can be made will be the lesser of (i) 15% of the number of shares of
Atlantes Common Stock issuable upon exercise of Atlantes Warrants outstanding
immediately prior to the Effective Time and (ii) such number as will be
determined by Metromail at the Effective Time such that the amount of cash
paid in respect of Atlantes Warrants does not exceed 15% of the sum of (x) the
amount of cash paid in respect of Atlantes Warrants and (y) the market value
as of the Effective Date of Metromail Common Stock delivered at the Effective
Time to holders of Atlantes Warrants. If cash elections are received for a
number of shares of Atlantes Warrants which exceeds the maximum number of
Atlantes Warrants for which a cash election is permitted, the Exchange Agent
will determine by lot (or by such other method as is deemed reasonable by
Metromail and Atlantes) which of the Atlantes Warrants for which a cash
election was made will be converted into cash.
 
  Atlantes Stock Options. Each holder of an Atlantes Stock Option will be
entitled to receive for each Atlantes Stock Option $25.99 in cash, less the
applicable exercise price of the option, instead of the number of shares of
Metromail Common Stock specified in clause (i) under "--Atlantes Stock
Options." There is no limitation to the number of Atlantes Stock Options for
which a cash election can be made.
   
  Procedure for Cash Election. Holders of Atlantes Common Stock, Atlantes
Warrants and Atlantes Stock Options who wish to exercise the cash election
with respect to all or a portion of their Atlantes Common Stock, Atlantes
Warrants and Atlantes Stock Options must complete a Form of Election, copies
of which have been mailed, together with this Proxy Statement/Prospectus, to
shareholders of record on the Atlantes Record Date and to holders of Atlantes
Warrants and Atlantes Stock Options. An election shall have been properly made
only if the Exchange Agent shall have received, by 5:00 P.M., New York time,
on June 27, 1997, the business day preceding the date of the Special Meeting
(the "Election Date"), a Form of Election properly completed and signed and
accompanied by the stock certificates, warrant certificates or stock option
agreements representing the shares of Atlantes Common Stock, Atlantes Warrants
or Atlantes Options, respectively, as to which the Form of Election relates.
Holders of Atlantes Common Stock, Atlantes Warrants and Atlantes Stock Options
who do not wish to receive cash instead of shares of Metromail Common Stock
need not return a Form of Election.     
 
  Any holder may at any time prior to the Election Date change such holder's
election by written notice received by the Exchange Agent at or prior to the
Election Date accompanied by a properly completed Form of Election. Metromail
and Atlantes shall have the right in their sole discretion and by mutual
agreement to permit changes in Elections after the Election Date.
 
  Any holder may at any time prior to the Election Date revoke such holder's
election by written notice received by the Exchange Agent at or prior to the
Election Date or by withdrawal prior to the Election Date of any stock
certificates, warrant certificates or stock option agreements previously
deposited with the Exchange Agent. Any revocation of an election may be
withdrawn by notice of such withdrawal delivered at or prior to the Election
Date. Any holder who shall have deposited any stock certificates, warrant
certificates or stock option agreements with the Exchange Agent shall again
have the right to withdraw such stock certificates, warrant certificates or
stock option agreements by written notice received by the Exchange Agent and
thereby revoke such holder's election as of the Election Date at any time
after the expiration of the period of 60 days following the Election Date if
the Merger shall not have been consummated prior thereto.
 
  Metromail and Atlantes shall have the right to make rules, not inconsistent
with the terms of the Merger Agreement, governing the validity of Forms of
Election and the manner and extent to which elections are to be taken into
account in making the determinations prescribed by the Merger Agreement.
 
 
                                      29
<PAGE>
 
NO FRACTIONAL SHARES
 
  No certificates or scrip representing a fractional share of Metromail Common
Stock will be issued upon the surrender for exchange of a certificate or
agreement representing immediately prior to the Effective Time a share of
Atlantes Common Stock ("Atlantes Certificate"), an Atlantes Warrant ("Warrant
Certificate") or an Atlantes Stock Option ("Option Agreement"); no Metromail
dividend or other distribution or stock split will relate to any such
fractional share; and no such fractional share will entitle the record or
beneficial owner thereof to any voting or other rights of a stockholder of
Metromail. In lieu of any such fractional share, each holder who would
otherwise have been entitled thereto upon the surrender of Atlantes
Certificates, Warrant Certificates or Option Agreements for exchange will be
paid, in addition to other cash payments to which such holder is otherwise
entitled, an amount in cash (without interest) determined by multiplying such
holder's fractional interest by the lesser of (i) the arithmetic mean of the
high and low trading prices on the NYSE of Metromail Common Stock on the
Effective Date, (ii) the last sale price on the Effective Date of Metromail
Common Stock and (iii) the arithmetic mean of the high and low trading prices
on the NYSE of Metromail Common Stock for the ten trading days immediately
preceding the Effective Date.
 
ADJUSTMENT OF EXCHANGE RATIO
 
  Appropriate and proportionate adjustments, if any, will be made to the
exchange ratio used to determine the number of shares of Metromail Common
Stock to which each holder of Atlantes Common Stock, Atlantes Warrants or
Atlantes Stock Options will be entitled upon conversion of such holder's
shares of Atlantes Common Stock, Atlantes Warrants or Atlantes Stock Options
in the event of any reclassification, stock split or stock dividend with
respect to Metromail Common Stock (or if a record date with respect to any of
the foregoing should occur) after the date of the Merger Agreement and prior
to the Effective Time.
 
CONTINGENT SHARES
 
  Each Record Holder will be entitled to receive Contingent Shares in the
years 1999 through 2002 depending on the achievement of certain performance
targets in each of the calendar years ending December 31, 1998 through 2001
(each, a "Measurement Period").
 
  The performance targets are based upon the number of Qualifying Records
loaded into Atlantes' or Metromail's database during each of the Measurement
Periods ("Annual Record Flow"). "Qualifying Records" means customer response
cards (which may be in electronic form) which (i) have been designed and
developed by Atlantes (or are cards designed and developed by another party,
but which meet certain specified criteria), (ii) seek responses from
purchasers of clients' products or services, (iii) seek certain demographic
and behavioral information, (iv) contain Acceptable Consumer Disclosure (as
defined in the Merger Agreement), and (v) are received by Atlantes with at
least the name and address information completed; provided that records that
contain a non-United States address and multiple records from the same person
for the same product will not be deemed Qualifying Records. The Merger
Agreement establishes targets for Annual Record Flow during each Measurement
Period (each a "Record Flow Performance Target") as follows: 12,000,000 for
the year ending December 31, 1998; 15,000,000 for the year ending December 31,
1999; 19,500,000 for the year ending December 31, 2000; and 24,000,000 for the
year ending December 31, 2001. Achievement of the performance targets is
measured by reference to the "Performance Percentage" which is determined by
dividing (i) the Annual Record Flow for such Measurement Period by (ii) the
applicable Record Flow Performance Target (such quotient being expressed as a
percentage).
 
  For each Measurement Period, Record Holders are entitled to receive, subject
to the provisions related to offset described under "--Right of Offset," a
contingent payment amount (the "Contingent Payment Amount") determined by
multiplying the Contingent Payment Target Amount for such Measurement Period
by the Payment Percentage for such Measurement Period. The "Contingent Payment
Target Amount" for each of the Measurement Periods is as follows: $2,500,000
for each of the years ending December 31, 1998, 1999 and 2000, and $5,000,000
for the year ending December 31, 2001. The "Payment Percentage" for a
Measurement Period
 
                                      30
<PAGE>
 
is determined by reference to the Performance Percentage for such Measurement
Period as follows: (i) if the Performance Percentage is less than 80%, then
the Payment Percentage is 0%; (ii) if the Performance Percentage is greater
than or equal to 80%, but less than 90%, then the Payment Percentage is 50%;
(iii) if the Performance Percentage is greater than or equal to 90%, but less
than 100%, then the Payment Percentage is 75%; and (iv) if the Performance
Percentage is greater than or equal to 100%, then the Payment Percentage is
equal to the Performance Percentage.
   
  For each Measurement Period, on a date (the "Contingent Share Delivery
Date") determined in accordance with the Merger Agreement (generally the March
15 next following the end of the Measurement Period), each Record Holder will
be entitled to receive, with respect to each share of Atlantes Common Stock
deemed to be held by such Record Holder, the number of validly issued, fully
paid and nonassessable shares of Metromail Common Stock determined by dividing
(i) the Contingent Payment Amount Per Share (as defined below) for the
applicable Measurement Period by (ii) the average of the per share closing
prices on the NYSE of Metromail Common Stock (as reported in the NYSE
Composite Transactions) during the ten consecutive trading days ending on the
trading day which is five trading days immediately preceding such Contingent
Share Delivery Date (the "Metromail Stock Price"). "Contingent Payment Amount
Per Share" with respect to a Measurement Period means the number determined by
dividing (i) the sum of the Contingent Payment Amount and the amount of
quarterly cash dividends Record Holders would have received had the Contingent
Share Delivery Date immediately followed the end of such Measurement Period by
(ii) the total number of shares of Atlantes Common Stock outstanding or
issuable upon exercise of outstanding Atlantes Warrants or Atlantes Stock
Options at the Effective Time. The provisions for allocation of Contingent
Shares between Record Holders who held Atlantes Common Stock, Atlantes
Warrants and Atlantes Stock Options are intended to place each holder of
Atlantes Warrants or Atlantes Stock Options in the same position with respect
to Contingent Shares as if the holder had exercised the Atlantes Warrants or
Atlantes Stock Options prior to the Merger.     
 
  No dividends will be paid to the Record Holders with respect to any
Contingent Shares unless and until certificates for such shares have been
issued, but upon issuance of such certificates, the Record Holders will be
paid dividends having a record date on or after the applicable Contingent
Share Delivery Date.
 
  No fractional shares of Metromail Common Stock will be issued or delivered
in respect of the issuance of Contingent Shares. In lieu of any fractional
shares to which a Record Holder would otherwise be entitled, each such Record
Holder will be entitled to receive a cash payment in an amount equal to (i)
the fraction of a share to which such Record Holder would otherwise have been
entitled multiplied by (ii) the Metromail Stock Price.
   
  The issuance of Contingent Shares to Record Holders is subject to certain
restrictions on the maximum number of shares to be issued and the maximum
aggregate Contingent Payment Amount to be received. The maximum number of
Contingent Shares to which Record Holders will be entitled in respect of
shares of Atlantes Common Stock, or in respect of shares of Atlantes Common
Stock and Atlantes Warrants, in each case held immediately prior to the
Effective Time, may not exceed the aggregate number of shares issued to such
holders at the Effective Time in respect of such shares of Atlantes Common
Stock, or in respect of shares of Atlantes Common Stock and Atlantes Warrants,
respectively. (There is no similar restriction with respect to Contingent
Shares delivered in respect of Atlantes Stock Options.) Further, the aggregate
Contingent Payment Amount to which Record Holders will be entitled to receive
may not exceed the amount equal to $12,500,000 (which represents the sum of
the Contingent Payment Target Amounts for the four Measurement Periods) less
the sum of the Contingent Payment Target Shortfalls. For each Measurement
Period, "Contingent Payment Target Shortfall" means the excess, if any, of the
Contingent Payment Target Amount over the Contingent Payment Amount, without
giving effect to any offset as described below. Such restriction only limits
the Contingent Shares to be issued prospectively, and thus, Record Holders
will not be obligated to return any Contingent Shares earned and delivered for
completed Measurement Periods.     
 
  Disputes concerning the achievement of any performance targets or the amount
of any losses to be offset by Metromail will be resolved as described below
under "--Resolution of Disputes."
 
                                      31
<PAGE>
 
  Following the occurrence of certain Exceptional Events, the Record Holders's
right to receive Contingent Shares will become fixed and will no longer be
based upon prospective achievement of performance targets. An "Exceptional
Event" means any of the following:
 
    (i) a final determination that Metromail has materially breached its
  obligations described under "THE MERGER--Operation of Atlantes after the
  Effective Time" and that such breach has materially adversely affected
  Atlantes's opportunity to meet the Record Flow Performance Targets;
 
    (ii) (A) the termination by Metromail or Atlantes of the employment with
  Metromail or Atlantes of any two of Messrs. Detmer, O'Neil or Anderson for
  any reason other than death, disability or "Cause" (as defined in their
  respective Employment Agreements) or (B) if any two of such persons
  terminate their employment with Metromail or Atlantes within three months
  after the occurrence with respect to such persons of a "Termination Event"
  (as defined in such person's Employment Agreement) if, in the case of
  either clause (A) or (B), such termination occurs prior to December 31,
  2001, in the case of Mr. Detmer, or December 31, 1999, in the case of
  Messrs. O'Neil or Anderson;
 
    (iii) a Change of Control (as defined in the Merger Agreement) of
  Atlantes, which includes the sale of substantially all the assets of
  Atlantes or if Metromail or its affiliates cease to own a majority of the
  outstanding shares of Atlantes Common Stock;
 
    (iv) the cessation by Atlantes (or a successor to Atlantes) of the
  business of collecting data through the use of customer response cards; or
 
    (v) the commencement by Atlantes or Metromail of a voluntary case under
  the federal bankruptcy laws or the filing of a petition against Atlantes or
  Metromail under the federal bankruptcy laws which petition is not dismissed
  within 90 days.
 
  If an Exceptional Event occurs after the Effective Date and on or prior to
December 31, 1998, then the Payment Percentage for each Measurement Period
will be deemed to be 100%. If an Exceptional Event occurs during any
Measurement Period (other than the first Measurement Period), then the Payment
Percentage for each Measurement Period not completed prior to the occurrence
of such Exceptional Event will be the percentage determined to be applicable
based on a Performance Percentage equal to the lesser of (i) 100% or (ii) the
average of the Performance Percentages for all Measurement Periods completed
prior to the occurrence of such Exceptional Event. The Contingent Share
Delivery Date with respect to each Measurement Period ending after the date of
the occurrence of such Exceptional Event will be not later than 15 days after
the end of such Measurement Period.
 
  If the Exceptional Event is an event described in clause (iii), clause (iv)
(unless the cessation of business described in such clause has occurred
following a change in regulatory requirements that in the reasonable judgment
of Metromail has made it inadvisable for Atlantes to continue such business)
or clause (v) of the definition of Exceptional Event, the Contingent Payment
Committee (as defined below) may, by notice to Metromail within 15 days
following the occurrence of such Exceptional Event, elect, on behalf of all
Record Holders, to have there be a single Contingent Share Delivery Date,
which date must be no later than 15 days following Metromail's receipt of such
notice, and for the Record Holders to receive in the aggregate, in lieu of all
Contingent Shares otherwise payable after the date of such Exceptional Event,
the number of shares of Metromail Common Stock determined by dividing (i) an
amount equal to the present value (using a discount rate determined in
accordance with the Merger Agreement) of the Contingent Payment Amounts
otherwise payable following such Exceptional Event in the absence of such
election by (ii) the Metromail Stock Price.
 
  Right of Offset. Metromail has the right to offset against the Contingent
Payment Amount (i) any and all Losses and Expenses (as defined below) incurred
by Metromail and its affiliates in connection with or arising from any breach
by Atlantes of any covenants in the Merger Agreement required to be performed
prior to the Effective Date or any breach of any warranty or inaccuracy of any
representation of Atlantes in the Merger Agreement as of the Effective Date,
(ii) the amount by which the accounts receivable of Atlantes as of the
Effective Date minus $5,000 exceed the amount collected in respect of such
receivables in the 12-month period
 
                                      32
<PAGE>
 
after the Effective Date, and (iii) the amount by which certain fees and
expenses of Atlantes in connection with the Merger exceed specified amounts.
"Losses" is defined in the Merger Agreement to mean losses, costs,
obligations, liabilities, settlement payments, awards, judgments, fines,
penalties, damages, deficiencies or other charges, and "Expense" is defined in
the Merger Agreement to mean expenses reasonably incurred in connection with
investigating, defending or asserting any claim, action or proceeding incident
to any matter for which Metromail is entitled to offset under the Merger
Agreement, including court filing fees, court costs, arbitration fees or
costs, witness fees and reasonable fees and disbursements of legal counsel,
investigators, expert witnesses, consultants, accountants and other
professionals.
 
  Metromail may not exercise its right of offset in respect of the items
described in clause (i) of the preceding paragraph until the aggregate amount
of Losses and Expenses exceeds $250,000, in which case the aggregate amount of
the offset in respect of such items will be limited to the amount by which
such Losses and Expenses exceeds $250,000. The right of offset will continue
until the obligations of Metromail to make any contingent payments have been
satisfied, provided that the right of offset on account of breaches of
warranty and inaccuracies of representations will terminate on the 18-month
anniversary of the Effective Date (other than with respect to certain
representations and warranties concerning the capitalization of Atlantes and
taxes), except that such rights will continue as to any Loss or Expense of
which Metromail has notified the Contingent Payment Committee before the date
such offset rights would otherwise terminate.
 
  Resolution of Disputes. Pursuant to the Merger Agreement, a "Contingent
Payment Committee" will be established, initially consisting of Mr. Detmer
(the current President and Chief Executive Officer of Atlantes), Kyle Lefkoff
(currently a director of Atlantes, the investment manager of CVM Equity Funds
III, Ltd. and a general partner of CVM Equity Funds IV, Ltd.) and Jeffrey H.
Schutz (Chairman of the Atlantes Board). Any vacancy in the Contingent Payment
Committee caused by the death, resignation or incapacity of a member will be
filled by the agreement of the remaining members or, if there are no remaining
members, by the written designation of Record Holders deemed to hold a
majority of the shares of Atlantes Common Stock immediately prior to the
Effective Time.
 
  Pursuant to the Merger Agreement, the Record Holders agree to indemnify the
Contingent Payment Committee ratably in accordance with their proportionate
interests in the Contingent Payment Amounts for any and all Losses and
Expenses imposed on, incurred by or asserted against the Contingent Payment
Committee in its capacity as such in any way relating to or arising out of the
Merger Agreement or the transactions contemplated thereby, and the Contingent
Payment Committee is entitled to direct Metromail to make any future
Contingent Payment Amounts to the Contingent Payment Committee to the extent
of such Losses and Expenses.
 
  The Contingent Payment Committee is empowered under the Merger Agreement to
review the determinations of Metromail with respect to the Annual Record Flow,
the Performance Percentage, the Payment Percentage and the Contingent Payment
Amount for each Measurement Period, to review any claim of offset that
Metromail may make and to take action, and incur expenses, on behalf of the
Record Holders with respect to any disputes that may arise with respect to
these matters. If the Contingent Payment Committee objects to Metromail's
determinations with respect to any Measurement Period and Metromail and the
Contingent Payment Committee are unable to resolve the objections, the matters
in dispute will be submitted to Arthur Andersen LLP for resolution.
 
  Pursuant to the Merger Agreement, Metromail must give written notice to the
Contingent Payment Committee of any claim on account of Losses and Expenses
for which a right of offset will be sought; provided, that the failure to
deliver written notice of any claim in respect of any action at law or any
suit in equity brought by a third party will not prejudice Metromail's rights
to offset unless such failure to give notice has materially prejudiced the
Record Holders. The Contingent Payment Committee will have the right to object
to any claim on account of Losses and Expenses within a period of 30 days
following the receipt of written notice from Metromail. Any dispute resulting
from the rejection of such claim will be resolved: (a) by a written agreement
between Metromail and the Contingent Payment Committee; (b) by binding
arbitration; or (c) by any other means to which Metromail and the Contingent
Payment Committee agree. Metromail will have the obligation to conduct
 
                                      33
<PAGE>
 
and control, through counsel of its choosing, the defense, compromise or
settlement of any third party claim as to which a right of offset will be
sought by Metromail; provided that the Contingent Payment Committee may
participate, through counsel chosen by it and at its own expense, in the
defense of any such claim, action or suit; and provided, further, that
Metromail will not, without the written consent of the Contingent Payment
Committee (which consent may not be unreasonably withheld), pay, compromise or
settle any such claim for which the Contingent Payment Committee has
acknowledged that a right of offset may exist following the written request
for such an acknowledgment as provided in the Merger Agreement. If Metromail
does not conduct the defense of any such third party claim, the Contingent
Payment Committee will have the right to do so, at the expense of Metromail,
but, in such case, the Contingent Payment Committee may not, without the
written consent of Metromail (which consent may not be unreasonably withheld),
compromise or settle such claim.
 
  If any claim to offset remains unresolved on a Contingent Share Delivery
Date, the portion of the Contingent Payment Amount, if any, which is not
subject to any claim of offset will be paid as described above under "--
Contingent Shares." Following the final determination of the amount of offset
pursuant to the procedures described above, any remaining Contingent Payment
Amount (without interest) which shall have been determined to be not subject
to offset shall be paid promptly, with the number of shares of Metromail
Common Stock to be delivered being determined by reference to the price of
Metromail Common Stock during the ten consecutive trading days ending five
trading days immediately preceding the date of delivery of shares representing
such payment.
 
  All objections to the determinations of the Contingent Payment Amounts for
each Measurement Period and all disputes concerning claims of offset must be
resolved no later than four years and 11 months after the Effective Date.
 
  Notwithstanding the foregoing, no later than five years after the Effective
Time, Metromail will transfer to the Exchange Agent, in trust for the Record
Holders, certificates representing the total number of Contingent Shares to be
paid, if any, pursuant to the Merger Agreement; and in no event will any
Contingent Shares be issued to a Record Holder more than five years after the
Effective Date.
 
  No Assignment of Rights by Record Holders. The right of each Record Holder
to receive shares of Metromail Common Stock pursuant to the Merger Agreement
may not be assigned or transferred in any manner whatsoever except by
operation of law or by will. In no event will any right to Contingent Shares
be evidenced by negotiable certificates of any kind.
 
EXCHANGE AGENT; PROCEDURES FOR EXCHANGE OF CERTIFICATES AND DELIVERY OF CASH
 
  American Stock Transfer and Trust Company has been selected to act as
Exchange Agent under the Merger Agreement. As soon as practicable after the
Effective Time (but no later than 30 days), (i) Metromail will deposit with
the Exchange Agent, in trust for the holders of Atlantes Certificates, Warrant
Certificates and Option Agreements, certificates representing the shares of
Metromail Common Stock issuable at the Effective Time ("Metromail
Certificates") in exchange for the outstanding shares of Atlantes Common
Stock, Atlantes Warrants and Atlantes Stock Options, and cash as required to
make payments in lieu of any fractional shares, and (ii) Metromail will make
available to the Surviving Corporation, which in turn will deposit with the
Exchange Agent in trust for the holders of Atlantes Certificates, Warrant
Certificates and Option Agreements, the cash into which the outstanding shares
of Atlantes Common Stock, Atlantes Warrants and Atlantes Stock Options have
been converted. The Exchange Agent will deliver the Metromail Certificates and
cash upon the surrender for exchange of the Atlantes Certificates, Warrant
Certificates and Option Agreements and a duly executed letter of transmittal.
 
  As soon as practicable after the Effective Time (but no later than 30 days),
the Exchange Agent will mail or otherwise deliver to each record holder of an
Atlantes Certificate, Warrant Certificate or Option Agreement, a letter of
transmittal, which shall specify that delivery shall be effected, and risk of
loss and title to the Atlantes Certificates, Warrant Certificates or Option
Agreements shall pass, only upon actual delivery thereof to the Exchange Agent
and shall contain instructions for use in effecting the surrender of the
Atlantes Certificates, Warrant Certificates or Option Agreements in exchange
for the property described in the next sentence. Upon
 
                                      34
<PAGE>
 
surrender for cancellation to the Exchange Agent of all Atlantes Certificates,
Warrant Certificates or Option Agreements held by any record holder of an
Atlantes Certificate, Warrant Certificate or Option Agreement together with
such letter of transmittal duly executed, such holder shall be entitled to
receive in exchange therefor (i) a Metromail Certificate representing the
number of whole shares of Metromail Common Stock into which the shares of
Atlantes Common Stock represented by the surrendered Atlantes Certificates,
Warrant Certificates or Option Agreement shall have been converted at the
Effective Time, (ii) any cash which such holder has the right to receive under
the provisions of the Merger Agreement described above under "--Conversion of
Shares," and (iii) the dividends and other distributions described in the
second succeeding paragraph. The Atlantes Certificates, Warrant Certificates
and Option Agreements so surrendered shall forthwith be cancelled.
 
  On each Contingent Share Delivery Date or as promptly as practicable
thereafter, Metromail will deposit with the Exchange Agent in trust for the
Record Holders Metromail Certificates representing the total number of
Contingent Shares, if any, to be paid on such Contingent Share Delivery Date.
The Exchange Agent will deliver any such Metromail Certificates (or cash in
lieu of any fractional shares) payable to the Record Holders at the addresses
of the Record Holders as they appeared on the stock records of Atlantes at the
Effective Time or such other addresses as the Record Holders provide to the
Exchange Agent by written notice.
 
  Any dividend or other distribution paid in respect of Metromail Common Stock
to holders of record on or after the Effective Date and otherwise payable to
the holder of an outstanding Atlantes Certificate, Warrant Certificate or
Option Agreement shall, until the surrender of such Atlantes Certificate,
Warrant Certificate or Option Agreement and the issuance of a Metromail
Certificate in respect thereof, be retained by Metromail, and no such dividend
or other distribution payable in respect of Metromail Common Stock shall be
paid to such holder until such Atlantes Certificate, Warrant Certificate or
Option Agreement shall have been so surrendered to Metromail. Upon surrender
of each such Atlantes Certificate, Warrant Certificate or Option Agreement and
issuance in exchange therefor of shares of Metromail Common Stock, there shall
be paid by Metromail to or at the direction of the holder of the Metromail
Certificate, the amount of all dividends and distributions which became
payable to holders of record on or after the Effective Date in respect of the
number of whole shares of Metromail Common Stock represented by the Metromail
Certificate so issued. In no event shall the holder of any Atlantes
Certificate, Warrant Certificate or Option Agreement be entitled to receive
interest on any of the funds to be received in the Merger or on any such
dividend or other distribution.
 
  Metromail or the Exchange Agent shall be entitled to deduct and withhold
from the consideration (cash, shares of Metromail Common Stock or any
combination thereof, as applicable) otherwise payable pursuant to the Merger
Agreement to any holder of shares of Atlantes Common Stock, Atlantes Warrants
or Atlantes Stock Options such amounts as Metromail or the Exchange Agent is
required to deduct and withhold with respect to the making of such payment
under the Code, or any provision of state, local or foreign tax law. To the
extent that amounts are so withheld by Metromail or the Exchange Agent, such
withheld amounts shall be treated for all purposes of the Merger Agreement as
having been paid to the holder of the shares of Atlantes Common Stock,
Atlantes Warrants or Atlantes Stock Options in respect of which such deduction
and withholding was made by Metromail or the Exchange Agent.

the Merger Agreement or the Parachute Proposal:
 
    (i) by mutual written consent of Metromail and Atlantes;
 
    (ii) by either Metromail or Atlantes if (A) the other (or Mergerco if
  Atlantes is the terminating party) has failed to comply in any material
  respect with any of its covenants or agreements contained in the Merger

  not qualified as to materiality or breaches any representation or warranty
  that is so qualified (in each case after a five business day cure period
  following notice of such breach) or (B) the shareholders of Atlantes have
  failed to approve the Merger at the Atlantes Special Meeting; or
 
    (iii) by either Metromail or Atlantes if (A) the Merger has not been
  effected on or prior to the close of business on August 31, 1997; provided,
  however, that the right to terminate the Merger Agreement pursuant to this

  If the Merger Agreement is terminated pursuant to its terms, such
termination will be without liability of any party to any other party to the
Merger Agreement; provided, that if such termination results from the willful

Metromail will pay the fees of The Wallach Company. Metromail has the right to
offset against the Contingent Payment Amount, expenses incurred by Atlantes

Agreement. See "--Contingent Shares."

above, terminated only by an instrument in writing signed by the party or
parties against which enforcement of such change, waiver, discharge or
termination is sought.

                              PARACHUTE PROPOSAL
   
  Under the so-called "Golden Parachute" rules of Section 280G of the Code, a
company cannot deduct, and Section 4999 of the Code imposes a 20% non-
deductible excise tax on, certain compensatory payments made by a corporation
that are contingent upon a change in the control of the corporation. For this
purpose, the value of the acceleration of the vesting of otherwise unvested
stock options is treated as a payment of such compensation. The Golden
Parachute rules are applicable if two conditions (among others) are satisfied.
First, the compensatory payments must be made to a person to whom these rules
apply (an employee or independent contractor, in either case, who is an
officer of the company, who is a shareholder that owns stock having a value
equal to the lesser of $1 million or 1% of the value of the stock of the
company or who is "highly compensated"). Second, the amount of the payment
must generally exceed three times the person's average annual compensation for
the period consisting of the most recent five taxable years ending prior to
the date of the change in control.     
 
  The Merger will result in a change in control of Atlantes under the Golden
Parachute rules. Atlantes is not making any material cash payments to
employees to whom the Golden Parachute rules apply. Moreover, although
employment agreements are being entered into by Metromail with three of
Atlantes' key officers, these employment agreements are not paid in
consideration for anything other than services to be rendered in the future
and are regarded by the parties as reasonable in light of the services to be
performed. Nevertheless, Atlantes will be treated as having made a payment
subject to these rules equivalent to the value (determined under Treasury
Regulations) of the acceleration of the vesting of employee stock options held
by persons subject to the Golden Parachute rules. Based upon proposed Treasury
Regulations, Atlantes has determined that in only one case does the value of
this acceleration exceed three times the average annual salary of a person to
whom these rules would apply.
   
  Jeffrey Schutz, a non-employee director of Atlantes, holds vested options to
acquire 3,600 shares of Atlantes Common Stock and holds unvested options to
acquire 2,400 shares of Atlantes Common Stock. The options for 1,200 shares
would vest on October 21, 1997 in the absence of the Merger, and the remaining
options would otherwise vest on October 21, 1998. The vested and unvested
options were issued to Mr. Schutz on October 21, 1994. These options,
consistent with all the options issued to Atlantes' employees, were subject to
a four-year vesting schedule, with 20% of the options becoming vested on the
date of grant and 20% on each anniversary of the date of the grant of the
options. Any unvested options would have been terminated if Mr. Schutz had
ceased to be a director. The exercise price of the options is $1.50 per share,
a price that was determined consistent with the manner in which Atlantes
priced the exercise prices at which options were granted to other employees.
The anticipated change in control of Atlantes resulting from the Merger will
accelerate the vesting of the options held by Mr. Schutz, which acceleration
will be subject to the Golden Parachute rules. Mr. Schutz has served as
director without compensation. Because Mr. Schutz has served without
compensation, his average annual compensation prior to the change in control
effectuated by the Merger will be $0, and any value of the acceleration of the
vesting of his unvested options would be subject to the Golden Parachute
rules.     
 
  A non-publicly traded company (such as Atlantes) can avoid the Golden
Parachute rules if appropriate approval for payments are made by a vote of
shareholders who own, immediately before the change in control, more than 75%
(by voting power) of the corporation's stock and who receive full and truthful
disclosure of the material facts and such additional information as is
necessary to make the disclosure not materially misleading at the time the
disclosure was made. In order to avoid the effect of the Golden Parachute
rules under this shareholder approval rule, proposed Treasury Regulations
require that a shareholder vote must determine the right of the particular
person to retain the payment (in this case the acceleration of the vesting of
options to acquire 2,400 shares). Accordingly, at the Atlantes Special
Meeting, shareholders of Atlantes will be asked to approve the Parachute
Proposal. Approval of the Parachute Proposal will require the affirmative vote
of the holders of at least 75% of the shares of Atlantes Common Stock
outstanding immediately prior to the Merger, disregarding shares owned by Mr.
Schutz. If the holders of all outstanding Atlantes Warrants were to exercise
such warrants prior to the Effective Time (assuming no holders of Atlantes
Stock Options were to exercise such options), the holders of approximately 91%
of the shares of Atlantes Common Stock outstanding on the Atlantes Record Date
(disregarding shares held by Mr. Schutz) would be required to approve the
Parachute Proposal.
 
  THE ATLANTES BOARD UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF ATLANTES
VOTE IN FAVOR OF APPROVAL OF THE PARACHUTE PROPOSAL.

  It is a condition to the obligations of Metromail to proceed with the Merger
that the Parachute Proposal be approved by holders of more than 75% of the
outstanding shares of Atlantes Common Stock (other than shares held by certain
disqualified persons). See "THE MERGER AGREEMENT--Conditions Precedent to the
Merger."
 
                               VOTING AGREEMENTS
 
  CVM Equity Fund III, Ltd. and CVM Equity Fund IV, Ltd., being the holders,
in the aggregate, of 193,760 shares of Atlantes Common Stock outstanding at
the close of business on the Atlantes Record Date (approximately 40.6% of the
shares of Atlantes Common Stock then outstanding), have signed agreements
obligating them to vote in favor of approval of the Merger Agreement and the
Parachute Proposal and against (i) any action or agreement that would result
in a breach of any covenant, representation or warranty, or any other
obligation or agreement, of Atlantes under the Merger Agreement and (ii) any
action that is intended, or that could be reasonably expected, to impede,
interfere with, delay, postpone or discourage, or adversely affect the
contemplated economic benefits to Metromail of the Merger and the actions or
transactions contemplated by the Merger Agreement.
 
                     DESCRIPTION OF METROMAIL COMMON STOCK
 
  The statements set forth under this heading with respect to the DGCL, the
Metromail Certificate of Incorporation, the Metromail By-laws and the Rights
Agreement dated as of February 24, 1997 (the "Metromail Rights Agreement")
between Metromail and American Stock Transfer and Trust Company, as Rights
Agent (copies of which have been filed as Exhibits to the Registration
Statement) are summaries thereof and do not purport to be complete; such
statements are subject to the detailed provisions of the DGCL, the Metromail
Certificate of Incorporation, the Metromail By-laws and the Metromail Rights
Agreement. See "AVAILABLE INFORMATION."
 
  The authorized capital stock of Metromail consists of 75,000,000 shares of
Metromail Common Stock and 20,000,000 shares of Preferred Stock, par value
$.01 per share (the "Metromail Preferred Stock"), of which 75,000 shares have
been designated as Metromail Series A Preferred Stock. At May 31, 1997,
22,256,900 shares of Metromail Common Stock were issued and outstanding,
2,700,000 shares of Metromail Common Stock were reserved for issuance pursuant
to various stock plans and 180,100 shares of Metromail Common Stock were held
as treasury stock. At May 31, 1997, no shares of Metromail Preferred Stock
were issued and 75,000 shares of Metromail Series A Preferred Stock were
reserved for issuance upon exercise of the Metromail Rights.
 
METROMAIL COMMON STOCK
 
  Holders of Metromail Common Stock are entitled to one vote for each share
held on all matters submitted to a vote of stockholders and do not have
cumulative voting rights. Accordingly, holders of a majority of the shares of
Metromail Common Stock entitled to vote in any election of directors may elect
all of the directors standing for election. Holders of Metromail Common Stock
are entitled to receive ratably such dividends, if any, as may be declared by
the Board of Directors out of funds legally available therefor, subject to any
preferential dividend rights of outstanding Metromail Preferred Stock. Upon
the liquidation, dissolution or winding up of Metromail, the holders of
Metromail Common Stock are entitled to receive ratably the net assets of
Metromail available after the payment of all debts and other liabilities and
subject to the prior rights of holders of any outstanding Metromail Preferred
Stock. Holders of Metromail Common Stock have no preemptive, subscription,
redemption or conversion rights. The outstanding shares of Metromail Common
Stock are, and the shares of Metromail Common Stock issued pursuant to the
Merger will be, when issued, fully paid and nonassessable. The rights,
preferences and privileges of holders of Metromail Common Stock are subject
to, and may be adversely affected by, the rights of the holders of shares of
any series of Metromail Preferred Stock which Metromail may designate and
issue in the future.
 
METROMAIL PREFERRED STOCK
 
  The Board of Directors of Metromail has the authority, subject to certain
limitations prescribed by law, without further vote or action by the
stockholders, to issue from time to time the Metromail Preferred Stock in one
or more classes or series and to fix or alter the designations, powers,
preferences, rights and any
 
                                      41
<PAGE>
 
   
qualifications, limitations or restrictions of the shares of each such class
or series thereof, including the dividend rates, conversion rights, voting
rights, terms of redemption (including sinking fund provisions), liquidation
preferences and the number of shares constituting each such class or series.
The issuance of Metromail Preferred Stock, while providing flexibility in
connection with possible acquisitions or other corporate purposes, may have
the effect of delaying, deferring or preventing a change of control of
Metromail. See "--Certain Charter and By-law Provisions; Metromail Rights
Agreement."     
 
CERTAIN CHARTER AND BY-LAW PROVISIONS; METROMAIL RIGHTS AGREEMENT
 
  Certain provisions of the Metromail Certificate of Incorporation and
Metromail By-laws, summarized in the following paragraphs, may be considered
to have an anti-takeover effect and may delay, deter or prevent a tender
offer, proxy contest or other takeover attempt that a stockholder might
consider to be in such stockholder's best interest, including such an attempt
as might result in payment of a premium over the market price for shares held
by stockholders.
 
Classified Board of Directors
 
  The Metromail Certificate of Incorporation provides for the Board of
Directors to be divided into three classes of directors serving staggered
three-year terms. As a result, approximately one-third of the Board of
Directors will be elected each year. Classification of the Board of Directors
expands the time required to change the composition of a majority of directors
and may tend to discourage a proxy contest or other takeover bid for
Metromail. Moreover, under the DGCL, in the case of a corporation having a
classified board of directors, the stockholders may remove a director only for
cause. These provisions, when coupled with provisions of the Metromail
Certificate of Incorporation authorizing only the Board of Directors to fill
vacant directorships, will preclude stockholders of Metromail from removing
incumbent directors without cause and simultaneously gaining control of the
Board of Directors by filling the vacancies with their own nominees.
 
Special Meetings of Stockholders
 
  The Metromail By-laws provide that special meetings of stockholders may be
called by the Chairman of the Board or the President and shall be called by
the President or the Secretary at the request in writing of a majority of the
Board of Directors of Metromail.
 
Advance Notice Requirements for Stockholder Proposals and Director Nominations
 
  The Metromail By-laws provide that stockholders seeking to bring business
before a meeting of stockholders, or to nominate candidates for election as
directors at a meeting of stockholders, must provide timely notice thereof in
writing. To be timely, a stockholder's notice must be delivered to, or mailed
and received at, the principal executive office of Metromail not less than 60
days nor more than 90 days prior to the scheduled meeting (or, if a special
meeting, not later than the close of business on the tenth day following the
earlier of (i) the day on which such notice of the date of the meeting was
mailed, or (ii) the day on which public disclosure of the date of the special
meeting was made). The Metromail By-laws also specify certain requirements
pertaining to the form and substance of a stockholder's notice. These
provisions may preclude some stockholders from making nominations for
directors at an annual or special meeting or from bringing other matters
before the stockholders at a meeting.
 
No Action by Written Consent of the Stockholders
 
  The Metromail Certificate of Incorporation does not allow the stockholders
of Metromail to take action by written consent.
 
Delaware Takeover Statute
 
  Section 203 of the DGCL ("Section 203") prohibits a public Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which such person became an interested stockholder unless: (i) prior to such
date, the Board of Directors approved either the business combination or the
transaction which resulted in the stockholder becoming an interested
stockholder; or (ii) upon becoming an interested stockholder, the stockholder
then owned at least
 
                                      42
<PAGE>
 
85% of the voting stock, as defined in Section 203; or (iii) subsequent to
such date, the business combination is approved by both the Board of Directors
and by holders of at least 66 2/3% of the corporation's outstanding voting
stock, excluding shares owned by the interested stockholder. For these
purposes, the term "business combination" includes mergers, asset sales and
other similar transactions with an "interested stockholder." An "interested
stockholder" is a person who, together with affiliates and associates, owns
(or, within the prior three years, did own) 15% or more of the corporation's
voting stock. Pursuant to the Metromail Certificate of Incorporation,
Metromail has expressly elected not to be governed by Section 203; provided
that this election does not apply to a business combination between Metromail
and R.R. Donnelley.
 
Limitations of Liability
 
  The Metromail Certificate of Incorporation contains a provision that is
designed to limit the directors' liability to the extent permitted by the DGCL
and any amendments thereto. Specifically, directors will not be held liable to
Metromail or its stockholders for an act or omission in such capacity as a
director, except for liability as a result of: (i) a breach of the duty of
loyalty to Metromail or its stockholders, (ii) actions or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) payment of an improper dividend or improper repurchase of
Metromail's stock under Section 174 of the DGCL, or (iv) actions or omissions
pursuant to which the director will receive an improper personal benefit. The
principal effect of the limitation of liability provision is that a
stockholder is unable to prosecute an action for monetary damages against a
director of Metromail unless the stockholder can demonstrate one of the
specified bases for liability. This provision, however, does not eliminate or
limit director liability arising in connection with causes of action brought
under the federal securities laws. The Metromail Certificate of Incorporation
does not eliminate its directors' duty of care. The inclusion of this
provision in the Metromail Certificate of Incorporation may, however,
discourage or deter stockholders or management from bringing a lawsuit against
directors for a breach of their fiduciary duties, even though such an action,
if successful, might otherwise have benefited Metromail and its stockholders.
This provision should not affect the availability of equitable remedies such
as injunction or rescission based upon a director's breach of the duty of
care.
 
Indemnification
 
  The Metromail By-laws also provide that Metromail will indemnify its
directors and officers to the fullest extent permitted by Delaware law.
Metromail is generally required to indemnify its directors and officers for
all judgments, fines, settlements, legal fees and other expenses incurred in
connection with pending or threatened legal proceedings because of the
director's or officer's position with Metromail or another entity that the
director or officer serves at Metromail's request, subject to certain
conditions, and to advance funds to its directors and officers to enable them
to defend against such proceedings. To receive indemnification, the director
or officer must have been successful in the legal proceedings or acted in good
faith and in what was reasonably believed to be a lawful manner in Metromail's
best interest.
 
Metromail Rights Agreement
 
  Pursuant to the Metromail Rights Agreement, each holder of an outstanding
share of Metromail Common Stock has received, and each person receiving a
share of Metromail Common Stock issued after the close of business on March 7,
1997 (the "Record Date") and prior to the earliest of the Distribution Date
(as defined below), the redemption of the Metromail Rights, the exchange of
the Metromail Rights and the expiration of the Metromail Rights (and, in
certain cases, following the Distribution Date), will receive one Metromail
Right. Each Metromail Right entitles the registered holder to purchase from
Metromail one one-thousandth of a share of Metromail Series A Preferred Stock
at a price of $100 per one one-thousandth of a preferred share (the "Metromail
Purchase Price"), subject to adjustment.
 
  Metromail Rights will be evidenced by certificates representing Metromail
Common Stock and not by separate certificates until the earlier to occur of
(i) the expiration of Metromail's redemption right following the date of
public disclosure that a person other than an Exempt Person (as defined below)
(an "Acquiring Person"), together with persons affiliated or associated with
such Acquiring Person, has acquired, or obtained the right to acquire,
beneficial ownership of 15% or more of the outstanding Metromail Common Stock
(the "Stock Acquisition Date") or (ii) the tenth business day after the date
of commencement or public disclosure of an intention to commence a tender
offer or exchange offer by a person other than an Exempt Person if, upon
 
                                      43
<PAGE>
 
consummation of the offer, such person could acquire beneficial ownership of
15% or more of the outstanding Metromail Common Stock (the earlier of such
dates being called the "Distribution Date"). The Metromail Rights Agreement
provides that, until the Distribution Date (or earlier redemption, exchange or
expiration of the Metromail Rights), the Metromail Rights will be transferred
with and only with the Metromail Common Stock. Until the Distribution Date (or
earlier redemption, exchange or expiration of the Metromail Rights), new
certificates evidencing Metromail Common Stock issued after March 7, 1997,
upon transfer or new issuance of Common Stock, will contain a notation
incorporating the Metromail Rights Agreement by reference. Until the
Distribution Date (or earlier redemption, exchange or expiration of the
Metromail Rights) the surrender for transfer of any certificate for Metromail
Common Stock, with or without such notation, will also constitute the transfer
of the Metromail Rights associated with the Metromail Common Stock represented
by such certificate. As soon as practicable following the Distribution Date,
separate certificates evidencing the Metromail Rights ("Metromail Right
Certificates") will be mailed to holders of record of Metromail Common Stock
as of the close of business on the Distribution Date, and such separate
Metromail Right Certificates alone will evidence the Metromail Rights.
 
  The Metromail Rights will first become exercisable after the Distribution
Date (unless sooner redeemed or exchanged). The Metromail Rights will expire
at the close of business on March 7, 2007 (the "Expiration Date"), unless
earlier redeemed or exchanged by Metromail as described below.
 
  The Metromail Purchase Price payable, and the number of shares of Metromail
Series A Preferred Stock or other securities, cash or other property issuable,
upon exercise of the Metromail Rights are subject to adjustment from time to
time to prevent dilution (i) in the event of a stock dividend or distribution
on, or a subdivision, combination or reclassification of, the Metromail Series
A Preferred Stock, (ii) upon the grant to holders of Metromail Series A
Preferred Stock of certain rights, options or warrants to subscribe for shares
of Metromail Series A Preferred Stock or securities convertible into shares of
Metromail Series A Preferred Stock at less than the current market price of
the Preferred Shares or (iii) upon the distribution to holders of shares of
Metromail Series A Preferred Stock of evidences of indebtedness or assets
(excluding regular periodic cash dividends) or of subscription rights or
warrants (other than those referred to above). In addition, the Metromail
Purchase Price payable and the number of shares of Metromail Series A
Preferred Stock purchasable, on exercise of a Metromail Right is subject to
adjustment in the event that Metromail should (i) declare or pay any dividend
on the Metromail Common Stock payable in Metromail Common Stock or (ii) effect
a subdivision or combination of Metromail Common Stock into a different number
of shares of Metromail Common Stock.
 
  In the event that there is public disclosure that an Acquiring Person has
become such, proper provision will be made so that each holder of a Metromail
Right, other than Metromail Rights that are (or were under certain
circumstances) beneficially owned by the Acquiring Person and certain related
persons and transferees (which will thereafter be void), on or after the
earlier of the Distribution Date and the first public disclosure that an
Acquiring Person has become such, will thereafter have the right to receive
upon exercise that number of shares of Metromail Common Stock (or other
securities) having (as of the date of occurrence of the triggering event) a
market value of two times the exercise price of a Metromail Right. In
addition, Metromail's Board of Directors has the option of exchanging all or
part of the Metromail Rights (excluding void Metromail Rights) for Metromail
Common Stock on a one-for-one basis in the manner described in the Metromail
Rights Agreement. In the event that, at any time following public disclosure
that an Acquiring Person has become such, Metromail is involved in a merger or
other business combination transaction where Metromail is not the surviving
corporation or where Metromail Common Stock is changed or exchanged or in a
transaction or transactions where 50% or more of its consolidated assets or
earning power are sold, proper provision will be made so that each holder of a
Metromail Right (other than the Acquiring Person and certain related persons
or transferees) shall thereafter have the right to receive, upon the exercise
thereof at the then current exercise price of the Metromail Right, that number
of shares of common stock of the acquiring company or Metromail, as the case
may be, which at the time of such transaction would have a market value of two
times the exercise price of the Metromail Right.
 
  No adjustment in the Metromail Purchase Price will be required until
cumulative adjustments require an adjustment of at least 1% in such Metromail
Purchase Price. No fractional shares of Metromail Series A
 
                                      44
<PAGE>
 
Preferred Stock will be issued (other than fractions which are integral
multiples of one one-thousandth of a shares of Metromail Series A Preferred
Stock, which may, at the election of Metromail, be evidenced by depositary
receipts) and in lieu thereof an adjustment in cash will be made based on the
market price of the shares of Metromail Series A Preferred Stock on the last
trading date prior to the date of exercise.
 
  At any time prior to public disclosure that an Acquiring Person has become
such, the Board of Directors of Metromail may redeem the Metromail Rights in
whole, but not in part, at a price of $.01 per Metromail Right (the
"Redemption Price"), payable in cash, shares (including fractional shares of
Metromail Common Stock or any other form of consideration deemed appropriate
by the Board of Directors. Immediately upon action of the Board of Directors
ordering redemption of the Metromail Rights, the ability of holders to
exercise the Metromail Rights will terminate and the only right of such
holders will be to receive the Redemption Price.
 
  At any time prior to a public disclosure that an Acquiring Person has become
such, the Board of Directors of Metromail may amend or supplement the
Metromail Rights Agreement, including without limitation, the beneficial
ownership percent at which a person becomes an Acquiring Person and the
definition of exempt person to include any person in addition to persons
described therein, without the approval of the Rights Agent or any holder of
the Metromail Rights, except for an amendment or supplement which would change
the Redemption Price. Thereafter, the Board of Directors of Metromail may
amend or supplement the Metromail Rights Agreement without such approval only
to cure ambiguity, correct or supplement any defective or inconsistent
provision or change or supplement the Metromail Rights Agreement in any manner
which will not adversely affect the interests of the holders of the Metromail
Rights (other than an Acquiring Person or an affiliate or associate thereof).
Immediately upon the action of the Metromail Board of Directors providing for
any amendment or supplement, such amendment or supplement will be deemed
effective.
 
  The shares of Metromail Series A Preferred Stock purchasable upon exercise
of the Metromail Rights will not be redeemable. Each share of Metromail Series
A Preferred Stock will be entitled to a minimum preferential quarterly
dividend payment equal to the greater of $25 per share and 1,000 times the
dividend declared per share of Metromail Common Stock. In the event of
liquidation, the holders of the shares of Metromail Series A Preferred Stock
will be entitled to a minimum preferential liquidation payment equal to the
greater of $100 per share and 1,000 times the payment made per share of
Metromail Common Stock. Each share of Metromail Series A Preferred Stock will
have 1,000 votes per share, voting together with the Metromail Common Stock.
In the event of any merger, consolidation or other transaction in which the
Metromail Common Stock is exchanged, each share of Metromail Series A
Preferred Stock will be entitled to receive 1,000 times the amount received
per share of Metromail Common Stock. The rights described in this paragraph
are protected by customary antidilution provisions.
 
  The Metromail Rights have certain anti-takeover effects. The Metromail
Rights may cause substantial dilution to a person that attempts to acquire
Metromail on terms not approved by the Board of Directors of Metromail, except
pursuant to an offer conditioned on a substantial number of Metromail Rights
being acquired. The Metromail Rights should not interfere with any merger or
other business combination approved by the Board of Directors prior to the
time a person has acquired beneficial ownership of 15% or more of Metromail
Common Stock, because until such time the Metromail Rights may generally be
redeemed by Metromail at $.01 per Metromail Right.
 
  Exempt Persons include R.R. Donnelley so long as (i) R.R. Donnelley is the
beneficial owner in the aggregate of not less than 15% of the outstanding
common stock of Metromail and (ii) the aggregate beneficial
ownership of R.R. Donnelley of the Metromail Common Stock is not in excess of
the base percentage owned by them at a specified time plus 2%. Exempt persons
also include certain transferees of R.R. Donnelley which beneficially own less
than 20% of the outstanding Metromail Common Stock.
 
  Until a Metromail Right is exercised, the holder thereof, as such, will have
no rights as a stockholder of Metromail, including, without limitation, the
right to vote or to receive dividends.
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for Metromail Common Stock is American
Stock Transfer and Trust Company.

                          COMPARISON OF THE RIGHTS OF
                       HOLDERS OF METROMAIL COMMON STOCK
                           AND ATLANTES COMMON STOCK
 
  The statements set forth under this heading with respect to the CBCA, the
DGCL, the Atlantes Charter, the Atlantes By-laws, the Metromail Certificate of
Incorporation, the Metromail By-laws and the Metromail Rights Agreement
(copies of which have been filed as Exhibits to the Registration Statement)
are brief summaries and do not purport to be complete; such statements are
subject to the detailed provisions of the CBCA, the DGCL, the Atlantes
Charter, the Atlantes By-laws, the Metromail Certificate of Incorporation, the
Metromail By-laws and the Metromail Rights Agreement. See "AVAILABLE
INFORMATION."
 
  The following summary compares certain rights of the holders of Atlantes
Common Stock to the rights of the holders of Metromail Common Stock. The
rights of Atlantes shareholders are governed principally by the CBCA, the
Atlantes Charter and the Atlantes By-laws. Upon effectiveness of the Merger,
such shareholders will become holders of Metromail Common Stock and their
rights will be governed principally by the DGCL, the Metromail Certificate of
Incorporation and the Metromail By-laws.
 
DIVIDEND RIGHTS
 
  The rights of Atlantes shareholders and Metromail stockholders with respect
to the receipt of dividends are substantially the same. See "DESCRIPTION OF
METROMAIL COMMON STOCK--Metromail Common Stock" and "SUMMARY--Market Prices
and Dividends Paid."
 
  Under the CBCA, a corporation may make a distribution to its shareholders
unless, after giving effect to such distribution, (i) the corporation would
not be able to pay its debts as they become due in the usual course of
business, or (ii) the corporation's total assets would be less than the sum of
its total liabilities plus (unless the articles of incorporation permit
otherwise) the amount that would be needed, if the corporation were to be
dissolved at the time of the distribution, to satisfy the preferential rights
upon dissolution of shareholders whose preferential rights are superior to
those receiving the distribution.
 
  Under the DGCL, a corporation may pay dividends out of surplus (defined as
the excess, if any, of net assets over capital) or, if no such surplus exists,
out of its net profits for the fiscal year in which such dividends are
declared and/or for its preceding fiscal year, provided that dividends may not
be paid out of net profits if the capital of such corporation is less than the
aggregate amount of capital represented by the outstanding stock of all
classes having a preference upon the distribution of assets.
 
VOTING RIGHTS
 
  Each share of Atlantes Common Stock and each share of Metromail Common Stock
entitles holders thereof to one vote on each matter submitted to a vote of
such holders. Neither the holders of shares of Atlantes Common Stock nor the
holders of shares of Metromail Common Stock have cumulative voting rights in
the election of directors.
 
  Under the CBCA, directors are elected by a plurality of the votes cast.
Pursuant to the Atlantes By-laws, other matters submitted to a vote of the
Atlantes shareholders require for approval the affirmative vote of a majority
of the shares represented at the meeting and entitled to vote on the subject
matter. However, the transitional provisions of the CBCA impose a two-thirds
voting requirement on certain actions, including actions to approve an
amendment to the Atlantes Charter and actions to approve a merger or plan of
share exchange. See "--Amendment to Charter Document" and "--Approvals of
Mergers and Asset Sales." For information regarding the comparable voting
rights of the holders of Metromail Common Stock, see "DESCRIPTION OF METROMAIL
COMMON STOCK--Metromail Common Stock."
 
DIRECTORS
 
  Number and Election of Directors; Removal. Under both the CBCA and the DGCL,
the charter document, and the by-laws of a corporation may specify the number
of directors. The Atlantes Charter provides that the
 
                                      46
<PAGE>
 
number of directors shall be no less than 3 (unless there are fewer than 3
shareholders of record). The Atlantes By-laws provide that the Atlantes Board
shall consist of not less than 3 nor more than 7 directors, each serving for a
term of one year, with the Atlantes shareholders and the Atlantes Board having
the authority to determine the exact number of directors. Any vacancy
occurring in the Atlantes Board or newly created directorship may be filled by
the affirmative vote of the remaining directors. The Atlantes By-laws also
provide that directors may be removed from office as provided by the CBCA.
Under the CBCA, the shareholders may remove a director under limited
circumstances either with or without cause. Atlantes has contractually agreed
that CVM Equity Fund III, Ltd. and CVM Equity Fund IV, Ltd. shall together
have the right to nominate and elect one member of the Atlantes Board so long
as either entity is a shareholder of Atlantes.
 
  For information regarding the number, election, removal and nomination of
Metromail Directors and the classification of the Metromail Board, see "Board
of Directors" under "DESCRIPTION OF METROMAIL COMMON STOCK--Certain Charter
and By-law Provisions; Metromail Rights Agreement."
 
  Fiduciary Duties of Directors. Under the CBCA, a director is required to
perform his or her duties as a director, including the duties as a member of
any committee of the directors upon which such director may serve, in good
faith, with the care that an ordinarily prudent person in a like position
would use under similar circumstances and in a manner such director reasonably
believes to be in the best interests of the corporation.
 
  Under the DGCL, the business and affairs of a corporation are managed by or
under the direction of its board of directors. In exercising their powers,
directors are charged with an unyielding fiduciary duty to protect the
interests of the corporation and to act in the best interests of its
stockholders. In recognition of the managerial prerogatives granted to the
directors of a Delaware corporation, Delaware law presumes that, in making a
business decision, such directors are disinterested and act on an informed
basis, in good faith and in the honest belief that the action taken was in the
best interests of such corporation, which presumption is known as the
"business judgment rule." A party challenging the propriety of a decision of a
board of directors bears the burden of rebutting the applicability of the
presumption of the business judgment rule by demonstrating that, in reaching
their decision, the directors breached one or more of their fiduciary duties--
good faith, loyalty and due care. If the presumption is not rebutted, the
business judgment rule attaches to protect the directors and their decisions,
and their business judgments will not be second guessed. Where, however, the
presumption is rebutted, the directors bear the burden of demonstrating the
entire fairness of the relevant transaction. Notwithstanding the foregoing,
Delaware courts subject directors' conduct to enhanced scrutiny in respect of
defensive actions taken in response to a threat to corporate control and
approval of a transaction resulting in a sale of such control.
 
  Liability of Directors. Both the CBCA and the DGCL permit a corporation to
limit the personal liability of its directors, with specified exceptions.
Under the CBCA, the articles of incorporation may provide that a director
shall not be liable for monetary damages for breach of fiduciary duty as a
director, provided, however, that such limitation of liability shall not apply
to any breach of the director's duty of loyalty to the corporation or to its
shareholders, acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, the payment of unlawful
distributions to shareholders as set forth in Section 7-108-403 of the CBCA or
any transaction from which the director directly or indirectly derived an
improper personal benefit. The Atlantes Charter does not limit the liability
of its directors.
 
  The DGCL permits a corporation to include in its charter a provision
limiting or eliminating the liability of its directors to such corporation or
its stockholders for monetary damages arising from a breach of fiduciary duty,
except for: (i) a breach of the duty of loyalty to the corporation or its
stockholders, (ii) acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) a declaration of a
dividend or the authorization of the repurchase or redemption of stock in
violation of the DGCL or (iv) any transaction from which the director derived
an improper personal benefit. The Metromail Certificate of Incorporation
eliminates director liability to the fullest extent permitted by the DGCL. See
"DESCRIPTION OF METROMAIL COMMON STOCK--Certain Charter and By-law Provisions;
Metromail Rights Agreement--Limitations of Liability."

CALL OF SPECIAL MEETINGS
 
  Under the CBCA, a special meeting of shareholders may be called by (i) the
board of directors or the persons authorized by the bylaws or resolution of
the board of directors to call such meeting or (ii) the written demand of
holders of 10% of the outstanding shares of a corporation entitled to be cast
on any issue proposed to be considered at the meeting. The Atlantes By-laws
provide that special meetings of Atlantes shareholders may be called by the
President, the Atlantes Board or holders of 10% or more of the outstanding
shares.
 
  The DGCL permits special meetings of stockholders to be called by the board
of directors and such other persons, including stockholders, as the
certificate of incorporation or bylaws may provide. The DGCL does not require
that stockholders be given the right to call special meetings.
 
  Meetings of stockholders of Metromail may be called only by the Chairman of
the Board, the President, or the President or the Secretary at the written
request of a majority of the Board of Directors. "See "DESCRIPTION OF
METROMAIL COMMON STOCK--Certain Charter and By-law Provisions; Metromail
Rights Agreement--Special Meetings of Stockholders."
 
ACTION BY SHAREHOLDERS WITHOUT A MEETING
 
  Under the CBCA, unless the articles of incorporation of such corporation
provide otherwise, any action that may be taken by shareholders at a meeting
may be taken without a meeting with the unanimous written consent of all
shareholders entitled to vote thereat. The Atlantes By-laws permit the
shareholders to so act by written consent in lieu of meeting.
 
  The DGCL permits the stockholders of a corporation to consent in writing to
any action without a meeting, unless the certificate of incorporation of such
corporation provides otherwise, provided such consent is signed by
stockholders having at least the minimum number of votes required to authorize
such action at a meeting of stockholders at which all shares entitled to vote
thereon were present and voted. The Metromail Certificate of Incorporation
does not permit stockholders to act without a meeting. See "DESCRIPTION OF
METROMAIL COMMON STOCK--Certain Charter and By-law Provisions; Metromail
Rights Agreement--No Action by Written Consent of the Stockholders."
 
SHAREHOLDER PROPOSALS
 
  The Metromail Certificate of Incorporation, but not the Atlantes Charter or
By-laws, restricts the manner in which nominations for Directors may be made
by stockholders. The Atlantes By-laws do not limit the ability of Atlantes
shareholders to bring other business before a meeting of shareholders. The
Metromail By-laws establish certain requirements that must be satisfied by a
stockholder in order to bring other business before a meeting of stockholders.
See "DESCRIPTION OF METROMAIL COMMON STOCK--Certain Charter and By-law
Provisions; Metromail Rights Agreement--Advance Notice Requirements for
Stockholder Proposals and Director Nominations."
 
AMENDMENT TO CHARTER DOCUMENT
 
  To approve a charter amendment proposed by the Board, the CBCA requires,
unless the articles of incorporation, the by-laws or any action by the board
of directors requires a greater vote, that the votes cast favoring approval
exceed the votes cast against such proposal or, in cases in which class voting
is required, such approval by each class. The Atlantes By-laws specifies that
the affirmative vote of a majority of the shares represented at the meeting
shall be required to approve any matter presented at such meeting. However,
for corporations incorporated prior to June 30, 1994, Section 7-117-101(7) of
the CBCA provides that unless the articles of incorporation of such
corporation contain a provision establishing the vote of the shareholders
required to amend the articles of incorporation, such amendment shall be
approved by each voting group entitled to vote separately on the amendment by
two-thirds of all the votes entitled to be cast on the amendment by that
voting group. Atlantes was incorporated prior to June 30, 1994, and the
Atlantes Charter is silent as to the required vote for approving an amendment
to the Atlantes Charter. Thus, the two-thirds voting requirement is applicable
to Atlantes.
 
  Under the DGCL and the Metromail Certificate of Incorporation, charter
amendments may generally be approved by the Metromail Board and the
affirmative vote of the holders of a majority of the outstanding shares of
voting stock entitled to vote thereon.
 
                                      48
<PAGE>
 
AMENDMENT AND REPEAL OF BY-LAWS
 
  With certain exceptions relating to quorum or voting requirements for
directors or shareholders, the CBCA provides that either the Board or the
shareholders may amend the by-laws. The Atlantes By-laws provide that they may
be altered, amended or repealed and new bylaws may be adopted by a majority of
the Atlantes Board present at any meeting of the Board of Directors at which a
quorum is present.
 
  Under the DGCL, holders of a majority of the voting power of a corporation
and, when provided in the Charter, the directors of the corporation, have the
power to adopt, amend and repeal the by-laws of a corporation. The Metromail
Certificate of Incorporation grants the Metromail Board of Directors such
power.
 
APPROVAL OF MERGERS AND ASSET SALES
 
  In addition to Board approval, the CBCA requires that mergers,
consolidations, dissolutions, and dispositions of all or substantially all of
a corporation's assets be approved, by each voting group entitled to vote
separately on such action, by a majority of all the votes entitled to be cast
on such proposal by that voting group unless the articles or the by-laws
specify a different proportion. The Atlantes Charter does not specify a
different proportion. However, for corporations incorporated prior to June 30,
1994, Section 7-117-101(8) of the CBCA provides that unless the articles of
incorporation of such corporation contain a provision establishing the vote of
the shareholders required to approve a plan of merger or a plan of share
exchange, such plan of merger or plan of share exchange shall be approved by
each voting group entitled to vote separately on the plan by two-thirds of all
the votes entitled to be cast on the plan by that voting group. Atlantes was
incorporated prior to June 30, 1994, and the Atlantes Charter is silent as to
the required vote for approving a plan of merger or plan of share exchange.
Thus, the two-thirds voting requirement is applicable to Atlantes.
 
  Under the DGCL, unless required by its charter (the Metromail Certificate of
Incorporation contains no such requirement), no vote of the stockholders of a
constituent corporation surviving a merger is necessary to authorize a merger
if: (i) the agreement of merger does not amend the charter of such constituent
corporation; (ii) each share of stock of such constituent corporation
outstanding prior to such merger is to be an identical outstanding or treasury
share of the surviving corporation after such merger; (iii) either no shares
of common stock of the surviving corporation and no shares, securities or
obligations convertible into such common stock are to be issued under such
agreement of merger, or the number of shares of common stock issued or
initially issuable does not exceed 20% of the number thereof outstanding
immediately prior to such merger; and (iv) certain other conditions are
satisfied. In addition, the DGCL provides that a parent corporation that is
the record holder of at least 90% of the outstanding shares of each class of
stock of a subsidiary may merge such subsidiary into such parent corporation
without the approval of such subsidiary's stockholders or board of directors.
Whenever the approval of the stockholders of a corporation is required for an
agreement of merger or consolidation or for a sale, lease or exchange of all
or substantially all of its assets, such agreement, sale, lease or exchange
must be approved by the affirmative vote of the holders of a majority of
outstanding shares of such corporation entitled to vote thereon.
 
DISSENTERS' RIGHTS
 
  Under the CBCA, dissenting shareholders are entitled to dissenters' rights
in connection with the sale, lease, exchange, transfer, or other disposition
of all or substantially all of the assets of a corporation and in certain
merger transactions. Shareholders of the surviving corporation are entitled to
dissenters' rights in any merger in which such shareholders are entitled to
vote on such merger. See "THE MERGER--Dissenters' Rights."
 
  The DGCL provides for appraisal rights only in the case of certain mergers
or consolidations and not (unless the certificate of incorporation of a
corporation so provides, which the Metromail Certificate of Incorporation does
not) in the case of other mergers, a sale or transfer of all or substantially
all of its assets or an amendment to its charter. Moreover, the DGCL does not
provide appraisal rights in connection with a merger or consolidation (unless
the certificate of incorporation so provides, which the Metromail Certificate
of
 
                                      49
<PAGE>
 
Incorporation does not) to the holders of shares of a constituent corporation
listed on a national securities exchange (or designated as a national market
system security by the National Association of Securities Dealers, Inc.) or
held of record by more than 2,000 stockholders, unless the applicable
agreement of merger or consolidation requires the holders of such shares to
receive, in exchange for such shares, any property other than shares of stock
of the resulting or surviving corporation, shares of stock of any other
corporation listed on a national securities exchange (or designated as
described above) or held of record by more than 2,000 holders, cash in lieu of
fractional shares or any combination of the foregoing. In addition, the DGCL
denies appraisal rights to the stockholders of the surviving corporation in a
merger if such merger did not require for its approval the vote of the
stockholders of such surviving corporation. See "--Approval of Mergers and
Asset Sales."
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The CBCA provides that a corporation may indemnify, against liability
incurred in a proceeding, a person made a party to the proceeding because the
person is or was a director if: (i) the person conducted himself or herself in
good faith and reasonably believed (a) in the case of conduct in an official
capacity with the corporation, that his or her conduct was in the
corporation's best interests and (b) in all other cases, that his or her
conduct was not opposed to the corporation's best interests, and (ii) in the
case of any criminal proceeding, the person had no reasonable cause to believe
his or her conduct was unlawful. A Colorado corporation may not indemnify a
director (i) in connection with a proceeding by or in the right of the
corporation in which the director was adjudged liable to the corporation, or
(ii) in connection with any other proceeding charging that the director
derived an improper personal benefit, whether or not involving action in an
official capacity, in which proceeding the director was adjudged liable on the
basis that he or she derived an improper personal benefit. The Atlantes By-
laws provide that Atlantes shall indemnify to the full extent authorized or
permitted by law, any person who was or is a party or is threatened to be made
a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative by reason of the fact
that he is or was a director or officer of Atlantes or is or was serving at
the request of Atlantes in any capacity with any other corporation,
partnership, joint venture, trust or other enterprise.
 
  Section 145 of the DGCL generally provides that a corporation may indemnify
its officers and directors who were or are a party to any action, suit, or
proceeding by reason of the fact that he was a director, officer, or employee
of the corporation by, among other things, a majority vote of a quorum
consisting of directors who were not parties to such action, suit, or
proceeding; provided that such officers and directors acted in good faith and
in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation. The Metromail Certificate of Incorporation
provides for indemnification of officers and directors to the fullest extent
permitted by Delaware law. The Metromail Certificate of Incorporation also
provides that Metromail may indemnify employees and agents of Metromail to the
fullest extent then permitted by Delaware law.
 
  Additionally, under the DGCL, advancement of expenses is permitted, but a
person receiving such advances must undertake to repay those expenses if it is
ultimately determined that he or she is not entitled to indemnification. The
Metromail Certificate of Incorporation provides that Metromail will (in the
case of any action, suit, or proceeding against a director) or may (in the
case of any action, suit or proceeding against an officer, trustee, employee
or agent) pay expenses incurred in defending a proceeding in advance of the
final disposition of such proceeding as authorized by the Metromail Board upon
receipt of the undertaking described above.
 
ANTI-TAKEOVER PROVISIONS
 
  There are no limitations under the CBCA with respect to interested
shareholder business combinations nor are there any restrictions in Atlantes
Charter or By-laws with respect to such interested shareholder transactions.
For information on such provisions of the DGCL, see "DESCRIPTION OF METROMAIL
COMMON STOCK--Certain Charter and By-law Provisions; Metromail Rights
Agreement--Delaware Takeover Statute."
 
                                      50
<PAGE>
 
RIGHTS OF INSPECTION
 
  Under both the CBCA and the DGCL, every stockholder, upon proper written
demand stating the purpose thereof and subject to certain other restrictions,
may inspect the corporate books and records as long as such inspection is for
a proper purpose and during normal business hours. Under both statutes, a
"proper purpose" is any purpose reasonably related to the interest of the
inspecting person as a stockholder.
 
LIQUIDATION RIGHTS
 
  The rights of the holders of Atlantes Common Stock upon the liquidation or
dissolution of Atlantes are substantially the same as the holders of Metromail
Common Stock upon the liquidation or dissolution of Metromail. See
"DESCRIPTION OF METROMAIL COMMON STOCK--Metromail Common Stock."
 
                              DISSENTERS' RIGHTS
 
  The following is a summary of Article 113 of the CBCA and the procedures for
Atlantes shareholders dissenting from the Merger Agreement and exercising
dissenters' rights. This summary is qualified in its entirety by reference to
Article 113 of the CBCA, which is attached hereto as Annex B. Annex B should
be reviewed carefully by any shareholder who wishes to exercise statutory
dissenters' rights or who wishes to preserve the right to do so. FAILURE
STRICTLY TO COMPLY WITH THE PROCEDURES SET FORTH IN ARTICLE 113 OF THE CBCA
WILL RESULT IN THE LOSS OF DISSENTERS' RIGHTS.
 
DISSENTERS' RIGHTS
 
  Under Article 113 of the CBCA ("Article 113"), if the Merger Agreement is
approved and the Merger is consummated, holders of Atlantes Common Stock who
exercise their dissenters' rights in accordance with Article 113 will be
entitled to have the "fair value" of their shares paid to them in cash by
complying with the provisions of Article 113. The term "fair value" is defined
in Article 113 to mean the value of the shares immediately before the
Effective Time, excluding any appreciation or depreciation in anticipation of
the Merger except to the extent that exclusion would be inequitable. Reference
herein to "dissenters' rights" is a general reference to a shareholder's right
to dissent to the Merger and obtain payment for the shareholder's shares in
accordance with Article 113.
 
WHO MAY DISSENT
 
  Each shareholder of Atlantes Common Stock may dissent to the Merger and
obtain payment of the fair value of the shareholder's shares by following the
procedures provided in Article 113 and summarized herein. The rights of the
shareholder may differ depending on whether the shareholder is a shareholder
of record holding shares for two or more beneficial shareholders or the
shareholder is a beneficial shareholder whose shares are held of record by one
or more record shareholders, as follows:
 
    (a) A record shareholder may assert dissenters' rights as to fewer than
  all the shares registered in the record shareholder's name only if the
  record shareholder dissents with respect to all shares beneficially owned
  by any one person and causes Atlantes to receive written notice which
  states (1) such dissent and (2) the name, address, and federal taxpayer
  identification number, if any, of each person on whose behalf the record
  shareholder asserts dissenters' rights.
 
    (b) A beneficial shareholder may assert dissenters' rights as to the
  shares held on the beneficial shareholder's behalf only if (1) the
  beneficial shareholder causes Atlantes to receive the record shareholder's
  written consent to the dissent not later than the time the beneficial
  shareholder asserts dissenters' rights, and (2) the beneficial shareholder
  dissents with respect to all shares beneficially owned by the beneficial
  shareholder.
 
  Atlantes may require that, when a record shareholder dissents with respect
to the shares held by any one or more beneficial shareholders, each such
beneficial shareholder must certify to Atlantes that the beneficial
shareholder and the record shareholder or record shareholders of all shares
owned beneficially by the beneficial
 
                                      51
<PAGE>
 
shareholder have asserted, or will timely assert, dissenters' rights as to all
such shares as to which there is no limitation on the ability to exercise
dissenters' rights. Any such requirement will be stated in the "Dissenters'
Notice" that is referred to below.
 
REQUIREMENTS TO BE MET BY A DISSENTER BEFORE THE VOTE ON THE MERGER AGREEMENT
IS TAKEN
 
  A shareholder who wishes to assert dissenters' rights must (a) cause
Atlantes to receive, before the vote is taken on the Merger Agreement, written
notice of the shareholders' intention to demand payment for the shareholder's
shares if the Merger Agreement is approved (the "Shareholder's Notice of
Intent to Dissent") and (b) not vote the shares in favor of the Merger
Agreement. A shareholder who does not satisfy the foregoing requirements is
not entitled to demand payment for the shareholder's shares under Article 113.
 
NOTICE REQUIRED TO BE GIVEN BY ATLANTES TO DISSENTING SHAREHOLDERS IF THE
MERGER AGREEMENT IS APPROVED
 
  If the Merger Agreement is approved, Atlantes will give a written
dissenters' notice (the "Dissenters' Notice") to each shareholder who has
complied with the provisions summarized above and who is entitled to demand
payment for shares under Article 113. The Dissenters' Notice may be given
before the Effective Date of the Merger and will in any event be given no
later than ten days after the Effective Date of the Merger. The Dissenters'
Notice will (a) state that the Merger Agreement was approved and state the
Effective Date or the proposed Effective Date of the Merger; (b) state an
address at which Atlantes will receive a Payment Demand (as defined below) and
the address of a place where certificates for certificated shares must be
deposited; (c) supply a Payment Demand form for demanding payment for shares,
which form will request the shareholder to state an address to which payment
is to be made; (d) set the date (the "Payment Demand Date") by which Atlantes
must receive the Payment Demand and certificates for shares, which Payment
Demand Date will not be less than thirty days after the date the Dissenters'
Notice is given; (e) if Atlantes has chosen to impose such a requirement,
state that, when a record shareholder dissents with respect to the shares held
by any one or more beneficial shareholders, each shareholder, and the record
shareholder or record shareholders of all shares owned beneficially by the
beneficial shareholder, have asserted, or will timely assert, dissenters'
rights as to all such shares as to which there is no limitation on the ability
to exercise dissenters' rights; and (f) be accompanied by a copy of Article
113.
 
DISSENTER'S PROCEDURES TO DEMAND PAYMENT
 
  If the shareholder has given a Shareholder's Notice of Intent to Dissent in
accordance with the provisions summarized above and wishes to assert the
shareholder's dissenters' rights (such a person being referred to in this
summary as a "Dissenter"), the Dissenter must (a) cause Atlantes to receive a
payment demand (the "Payment Demand," which may, but need not, be on the
Payment Demand form provided by Atlantes with the Dissenter's Notice), duly
completed, and (b) deposit the Dissenter's certificates for shares. A
Dissenter will have all rights of a shareholder, except the right to transfer
the shares, until the Effective Date of the Merger but will have, after the
Effective Date of the Merger, only the right to receive payment of the shares
as to which payment has been demanded.
 
  The Payment Demand and deposit of certificates by a Dissenter will be
irrevocable unless (1) the Effective Date has not occurred within sixty days
after the Payment Demand Date, or (2) Atlantes fails to make payment to the
Dissenter, within sixty days after the Payment Demand Date, of the amount
Atlantes estimates to be the fair value of the Dissenter's shares, plus
accrued interest. If the Effective Date of the Merger is more than sixty days
after the Payment Demand Date, then Atlantes will be required to send a new
Dissenters' Notice and the provisions summarized above will again be
applicable.
 
                                      52
<PAGE>
 
  If a Dissenter fails to demand payment and deposit certificates representing
the shares as to which dissent is made, as required by the Dissenters' Notice,
by the Payment Demand Date, the Dissenter will not be entitled to payment for
the shares under Article 113 and will become a shareholder in Metromail as if
the Dissenter has not exercised any dissenters' right.
 
PAYMENT FOR SHARES
 
  Upon the Effective Date of the Merger, or upon receipt of a Payment Demand
given in accordance with the provisions of Article 113, whichever is later,
Atlantes will pay each Dissenter who has complied with the requirements for
demanding payment stated in Article 113, at the address stated in the Payment
Demand, or, if no such address is stated in the Payment Demand, at the address
shown on Atlantes's current record of shareholders for the record shareholder
holding the Dissenter's shares, the amount Atlantes estimates to be the fair
value of the Dissenter's shares, plus accrued interest. The payment will be
accompanied by: (a) Atlantes's balance sheet, statement of changes in
shareholders' equity, statement of cash flow and other financial statements
complying with the requirements of Section 7-113-206(2)(a); (b) a statement of
Atlantes's estimate of the fair value of the shares; (c) an explanation of how
the interest was calculated; (d) a statement of the Dissenter's right to
demand payment in accordance with the provisions of Article 113 regarding the
Dissenter's Responsive Notice summarized below; and (e) a copy of Article 113.
 
FAILURE TO EFFECT MERGER
 
  If the Effective Date of the Merger does not occur within sixty days after
the Payment Demand Date, Atlantes will return the deposited certificates. If
the Effective Date of the Merger occurs more than sixty days after Payment
Demand Date, then Atlantes shall send a new Dissenters' Notice, as provided in
Section 7-113-203, and the appropriate provisions of Article 113 shall again
be applicable.
 
SHARES ACQUIRED AFTER ANNOUNCEMENT OF MERGER AGREEMENT
 
  Atlantes may, in or with the Dissenters' Notice, state the date of the first
announcement to news media or to shareholders of the terms of the Merger
Agreement (the "Announcement Date") and state that the Dissenter must certify
in writing, in or with the Payment Demand, whether or not the Dissenter (or
the person on whose behalf the Dissenter asserts dissenters' rights) acquired
beneficial ownership of the shares before the Announcement Date. With respect
to any Dissenter who does not so certify in writing, in or with the Payment
Demand, that the Dissenter or the person on whose behalf the Dissenter asserts
dissenters' rights acquired beneficial ownership of the shares before the
Announcement Date, Atlantes may, in lieu of making payment for the shares,
offer to make such payment if the Dissenter agrees to accept the payment in
full satisfaction of the demand. Any such offer will include: (a) Atlantes's
balance sheet, statement of changes in shareholders' equity, statement of cash
flow and other financial statements complying with the requirements of Section
7-133-206(2)(a); (b) a statement of Atlantes's estimate of the fair value of
the shares; (c) an explanation of how the interest was calculated; (d) a
statement of the Dissenter's right to demand payment in accordance with the
provisions of Article 113 regarding the Dissenter's Responsive Notice
summarized below; and (e) a copy of Article 113.
 
PROCEDURE FOR DISSENTER TO FOLLOW IF DISSENTER IS DISSATISFIED WITH PAYMENT
MADE OR OFFERED BY ATLANTES
 
  A Dissenter may give notice (the "Dissenter's Responsive Notice") to
Atlantes in writing of the Dissenter's estimate of the fair value of the
Dissenter's shares and of the amount of interest due and may demand payment of
such estimate (less any payment made by Atlantes as contemplated above) or may
reject Atlantes's offer made as contemplated above with respect to shares
acquired after the Announcement Date and may demand payment of the fair value
of the shares and interest due, if: (a) the Dissenter believes that the amount
paid or offered by
 
                                      53
<PAGE>
 
Atlantes, as the case may be, is less than the fair value of the shares or
that the interest due was incorrectly calculated; (b) Atlantes fails to make
payment within sixty days after the Payment Demand Date, or (c) Atlantes does
not return the deposited certificates or release the transfer restrictions
imposed on uncertificated shares as required if the Effective Date of the
Merger has not occurred within sixty days after the Payment Demand Date. A
Dissenter waives the right to demand payment as outlined above unless the
Dissenter causes Atlantes to receive the Dissenter's Responsive Notice within
thirty days after Atlantes made or offered payment for the Dissenter's shares.
 
COURT ACTION FOR APPRAISAL
 
  If the Dissenter's demand for payment pursuant to the Dissenter's Responsive
Notice remains unresolved, Atlantes may, within sixty days after receiving the
Dissenter's Responsive Notice, commence a proceeding and petition the district
court of Denver County, Colorado to determine the fair value of the
Dissenter's shares and accrued interest. If the Dissenter's demand for payment
remains unresolved within that sixty day period and Atlantes does not commence
the proceeding within that period, Atlantes must pay to the Dissenter the
amount demanded in the Dissenter's Responsive Notice.
 
  Atlantes shall make all Dissenters whose demands remain thus unresolved
parties to the proceeding as in an action against their shares, and all
parties shall be served with a copy of the petition in the manner provided in
Article 113. The court may appoint one or more persons as appraisers to
receive evidence and recommend a decision on the question of fair value. The
appraisers have the powers described in the order appointing them, or in any
amendment to such order. The parties to the proceeding are entitled to the
same discovery rights as parties in other civil proceedings. Each Dissenter
made a party to the proceeding will be entitled to judgment for the amount, if
any, by which the court finds the fair value of the Dissenter's shares, plus
interest, exceeds the amount paid by Atlantes, or for the fair value, plus
interest, of the Dissenter's shares for which Atlantes elected to withhold
payment under the provisions outlined above.
 
  The court will determine all costs of the proceeding, including the
reasonable compensation and expenses of appraisers appointed by the court, and
will assess the costs against Atlantes; except that the court may assess costs
against all or some of the Dissenters, in amounts the court finds equitable,
to the extent the court finds the Dissenters acted arbitrarily, vexatiously,
or not in good faith in demanding payment. The court may also assess the fees
and expenses of counsel and experts for the respective parties, in amounts the
court finds equitable, (a) against Atlantes and in favor of any Dissenters if
the court finds Atlantes did not substantially comply with the requirements of
part 2 of Article 113; or (b) against either Atlantes or one or more
Dissenters, in favor of any other party, if the court finds that the party
against whom the fees and expenses are assessed acted arbitrarily,
vexatiously, or not in good faith with respect to the rights provided in
Article 113. If the court finds that the services of counsel for any Dissenter
were of substantial benefit to other Dissenters similarly situated, and that
the fees for those services should not be assessed against Atlantes, the court
may award to said counsel reasonable fees to be paid out of the amounts

                  ADDITIONAL INFORMATION REGARDING METROMAIL
 
                             BUSINESS OF METROMAIL
 
GENERAL
 
  Metromail is a leading provider of database marketing, direct marketing and
reference products and services in the United States and the United Kingdom.
Metromail helps its customers identify and reach targeted audiences utilizing
its comprehensive, proprietary consumer database encompassing more than 90% of
the households in the United States, as well as providing database marketing
software and related services. Metromail provides its information, information
services and software services to a wide variety of organizations engaged in
direct mail, telephone and target marketing, as well as to clients who desire
specific reference and information services. Its clients include Fortune 500
companies, as well as numerous mid-size and small businesses.
 
  Metromail was incorporated under the laws of the State of Delaware in 1979.
It is a successor to several predecessor businesses, including a list
development business that was started in 1946. Metromail became a public
company in 1984 and remained so until mid-1987 when it was acquired by R. R.
Donnelley. Metromail has made several acquisitions, including the acquisition
in 1994 of the assets of Customer Insight Company, a company that develops PC-
based marketing oriented database solutions ("CIC"). Data by Design, a
database marketing consulting service in the United Kingdom ("DBD"), and
International Communication & Data Plc, a compiler of lists in the United
Kingdom primarily through the use of surveys ("ICD"), were acquired by R. R.
Donnelley in 1994 and 1995, respectively. Metromail managed the United Kingdom
operations since their acquisition by R. R. Donnelley, with ownership being
transferred to Metromail in early 1996. On June 19, 1996, Metromail completed
an initial public offering of 13,800,000 shares of its common stock (the
"IPO"), resulting in the reduction of R. R. Donnelley's ownership in Metromail
to approximately 38.4%.
 
PRODUCTS AND SERVICES
   
  Metromail provides three general categories of products and services to its
clients: Database Marketing Services (including database marketing software
and services and list enhancement services), Direct Marketing Services
(including list development and personalization printing and lettershop
services) and Reference Services (including on-line services and directory
publishing). Database Marketing Services accounted for 29.0%, 28.4% and 27.1%
of Metromail's total net sales in the years ended December 31, 1994, 1995 and
1996, respectively; Direct Marketing Services accounted for 51.2%, 51.6% and
53.6% of Metromail's total net sales in the years ended December 31, 1994,
1995 and 1996, respectively; and Reference Services accounted for 19.8%, 20.0%
and 19.3% of total net sales in 1994, 1995 and 1996, respectively     
 
 Database Marketing Services
 
  Database Marketing Software and Services. Metromail, through CIC, provides
PC-based database marketing products and services to clients that possess a
large amount of internal and external data and need a way to assemble and
analyze the data to determine their appropriate marketing initiatives.
Metromail's software products are designed to enable each client to maintain
its database on its own personal computer for quick desktop access to
information. Alternatively, the client can choose to have Metromail house the
client's database on the mainframe computer in Metromail's Lombard, Illinois
data center and, with the use of Metromail's proprietary MetroBase software
loaded on the client's personal computers, analyze the files contained in the
client's database and generate desired reports through on-line access.
 
  Metromail targets a variety of industries for these software products and
services, focusing on the financial services, telecommunications, catalog,
publishing, cable television, transportation, entertainment and travel-related
services industries. Metromail currently supports over 2,000 installations of
these products at over 340 client sites.
 
                                      55
<PAGE>
 
  Metromail's software products provided by CIC are licensed to clients,
generally for a three-year period. A substantial portion of the license fee is
paid at the time the license agreement is entered into with the balance due
upon completion of installation. In addition, Metromail collects an annual
license and maintenance fee that is approximately 20% of the initial license
fee. In connection with some installations, Metromail, as a service, purchases
and re-sells to the client certain computer equipment such as storage devices
and other peripherals.
 
  List Enhancement Services. Metromail improves the quality of lists or
databases provided by its clients by eliminating duplicate names, correcting
addresses and ZIP codes and appending additional information, such as
telephone numbers or other marketing-related characteristics, to the lists or
databases.
 
  Metromail's list enhancement services enable a client to process information
utilized in direct mail campaigns. These processes help Metromail's clients
identify persons on lists supplied by the client likely to respond favorably
to the client's mailing, improve the delivery of the items mailed and reduce
the postage costs of a direct mail campaign. Typically, a client sends to
Metromail hundreds of lists, aggregating millions of names that have been
rented from list brokers or other sources and the client's current customer
list. Using its computer resources and proprietary software, Metromail
consolidates these lists, corrects addresses and ZIP codes and eliminates
duplicate names (the merge/purge process). A client can enhance this
consolidated list by incorporating certain of the characteristics contained in
Metromail's database and/or INSOURCE, an enhancement database that combines
Metromail's National Consumer Database and other proprietary databases with
the consumer databases of Experian Information Solutions Inc. (formerly TRW
Target Marketing Services) to provide in-depth information on approximately
95% of all U.S. households. INSOURCE, introduced in late 1996, is able to
append more than 300 data variables to customer records, including hobbies,
interests, product preferences and investment, educational and occupational
information. Metromail believes INSOURCE is the most complete enhancement
database currently available in the market.
 
  Metromail also uses its database to enhance a client's proprietary customer
list and to make that list more deliverable. Metromail has non-exclusive
licenses from the United States Postal Service for certain services, such as
National Change of Address, Delivery Sequence File and Locatable Address
Conversion System, to facilitate these processes. These enhancements usually
include adding information from Metromail's database, eliminating
undeliverable addresses and verifying households at a particular address. ZIP
codes and addresses on a proprietary list can be corrected and telephone
numbers can be added. In addition, Metromail saves its clients money on the
mailing of these enhanced lists by carrier route coding, ZIP code presorting
and overlaying 9-digit ZIP codes.
 
  Metromail provides list enhancement services to approximately 400 clients
annually, most of whom are involved in continuity marketing (e.g., record
clubs), financial services, insurance, magazine and book publishing, mail
order and catalog merchandising or retail. Metromail provides these services
primarily from its facilities in Lombard, Illinois.
 
 Direct Marketing Services
 
  List Development Services. Metromail assists clients in implementing cost-
effective direct marketing strategies by creating for its clients lists of
those individuals and households in the client's trade area having the
characteristics that fit the marketing strategy and are most likely to respond
favorably to the client's marketing efforts. Metromail provides customized
list development services to two primary groups of clients: sales promotion
and mail order organizations. Sales promotion clients generally have
determined the characteristics of their target customers and provide Metromail
with a trade area definition and a customer profile. Metromail then uses its
computer software and database to identify the individuals and households in
the customer's trade area who have the characteristics that the client has
specified and compiles a list of those individuals and households.
 
  Mail order clients use Metromail's marketing services and statistical
software to identify the geographic, demographic and other marketing
characteristics in Metromail's database that singly and in combination
describe the best prospects for the client's direct marketing campaign.
Metromail reviews the client's customer files and direct marketing experience,
as well as syndicated research, publicly available marketing data, and
relevant historical information and marketing research in Metromail's
database. In addition, Metromail may design,
 
                                      56
<PAGE>
 
conduct and analyze market surveys or test mailings. From this research and
testing Metromail defines relevant market segments and their respective sizes
and ranks these segments according to their relative potential value to the
client.
 
  Metromail provides lists to approximately 15,000 clients annually. Metromail
generates most of its list sales from sales to consumer goods manufacturers,
financial institutions, magazine publishers, mail order houses and not-for-
profit organizations. These lists are used for targeted mailings, telephone
marketing campaigns and statistical samplings. Except for test mailings, these
list orders range in size from 500 to 20 million households and prices
generally range from $7 to $250 per thousand names, although requests for
certain information may be as high as $1,000 per thousand names. Lists are
generally delivered in the form of computer tape or mailing labels. Metromail
provides its list development services from its facilities in Lincoln,
Nebraska.
 
  Personalization Printing and Lettershop Services. Metromail's
personalization printing and lettershop services frequently are used in
conjunction with list development and enhancement services provided by
Metromail. In 1996, 22 of Metromail's top 25 list development and enhancement
clients used these services in addition to its list services. Metromail
provides processing and mailing services to direct mail advertisers from
facilities located in Mt. Pleasant, Iowa; Rutland, Vermont; Seward, Nebraska;
and Lincoln, Nebraska.
 
  Personalization printing involves applying addresses and variable text to
direct mail pieces. Lettershop services consist of forms trimming, folding,
affixing special items (such as coins, medallion or cards), inserting
materials into envelopes, polywrapping, applying address labels and mailing.
In connection with these services, Metromail uses both addresses generated
from its own database and addresses provided by its customers. Lettershop
services are typically contracted for on an individual mailing basis.
Contracts range in size from relatively small test mailings and statistical
samplings to major promotions of up to 25 million pieces.
 
  Metromail is one of the largest providers of commercial lettershop services
in the United States. At its three lettershop facilities, Metromail has the
capacity to insert material in more than 6.5 million envelopes per day,
package 10 million product samples per month and polywrap 26 million packages
per month. Metromail has installed and improved special equipment in its
production facilities that permits production of a high volume of polywrapped
advertising materials. Metromail has also established an integrated
computerized system of scheduling, production and inventory control.
 
  Metromail's lettershop services processed over 1.2 billion pieces of mail in
1996. To expedite mailing of materials, United States Postal Service personnel
have been permanently assigned to each of the lettershop facilities.
 
 Reference Services
 
  On-Line Services. Metromail offers a number of services that involve the
need for immediate electronic access to information contained in Metromail's
database. The most important of these services are Metromail's MetroNet and
National Directory Assistance ("NDA") services.
 
  Metromail's MetroNet service provides users with on-line or electronic
access to Metromail's MetroNet Master file (a subset of Metromail's database),
change of address files, business listings and regional Bell operating
companies' electronic directory assistance databases. These services are
marketed primarily to collection agencies, consumer finance companies and
credit card issuers. This service is used by many of Metromail's clients to
confirm certain information that is contained on credit applications submitted
to them (such as name and address, but not credit history).
 
  Metromail's NDA services provide on-line access to a database consisting of
more than 108 million residential, business and government listings, as well
as on-line access to the electronic directory assistance databases maintained
by the regional Bell operating companies. Metromail markets these services,
which were
 
                                      57
<PAGE>
 
commenced in 1995, to telephone companies, operator service providers and
other organizations with high-volume directory assistance needs. As of
December 31, 1996, Metromail had entered into contracts to provide these
services to approximately 25 clients. Metromail is in various stages of
testing with some of these clients and at the end of 1996 was sending invoices
to 23 clients for services being provided by Metromail.
 
  Directory Publishing Services. Metromail publishes the Cole directories,
local "reverse" directories covering approximately 150 urban and suburban
areas in the United States and Canada, including New York, Boston,
Philadelphia, Dallas and Houston. These directories, which contain
approximately 32 million residential and business listings, are available
either in printed form or on CD-ROM. The directories are derived from
Metromail's database and contain listings arranged by street address and
telephone number. Many of the directories also include census demographic data
on a neighborhood basis and historical data, such as duration of residence.
 
  Metromail has approximately 48,000 clients annually for the printed Cole
directories and approximately 3,000 clients for its Cole and MetroSearch CD-
ROM products. The clients for these products are principally collection
agencies, financial institutions, government agencies, insurance brokers and
agents, local merchants such as home improvement businesses, and real estate
brokers. The Cole directories are primarily used by clients to market products
or services to prospects or to identify individuals at specific addresses or
telephone numbers within a specific geographic area. The Cole directories are
supplied on an annual subscription basis for prices ranging from $75 to over
$600, depending on the size of the market. In 1996, approximately 73% of
leases for Cole directories were renewed.
 
  Metromail publishes, prints and binds the Cole directories at its Lincoln,
Nebraska facility. In addition, Metromail provides certain printing and
binding services for other publishers of short-run directories.

INTERNATIONAL OPERATIONS
 
  Metromail's international operations consist primarily of its operations in
the United Kingdom of ICD, one of Britain's leading consumer lifestyle and
financial list developers and providers, and DBD, a provider of database
marketing consulting services. ICD acquires consumer lifestyle data primarily
through mailed surveys. During 1996, ICD received lifestyle data for 3.5
million individuals, bringing the number of individuals included in
Metromail's lifestyle file to 8.6 million. Another ICD product, the British
Investor Database, is compiled from share registers and contains 7.7 million
share transactions. More than 2,000 companies either sponsor survey questions
or rent data from ICD. Through DBD, ICD also offers a range of high value
analytical and consultancy services.
 
METROMAIL'S DATABASE
 
  Metromail maintains and continually updates a large proprietary database
that contains geographic, demographic, individual and other marketing
information on over 90% of the households in the United States. Metromail
believes that its database is one of the most complete, highest quality and
up-to-date direct marketing databases in the United States and is a principal
reason that clients use Metromail's list development and enhancement services.
This database contains numerous characteristics relating to the individuals
and households reflected in the database in addition to name, address and
telephone number. Examples of these characteristics include age, length of
residence at a particular address, dwelling unit type, gender of the head of
household, presence of other family members, estimated household income and
home ownership.
 
                                      58
<PAGE>
 
  Metromail has been accumulating data for almost 50 years, and management
believes that its processes of gathering data from numerous sources and
modifying and updating its database represent a significant competitive
advantage for Metromail.
 
  Metromail derives the data included in its database from a wide variety of
publicly available sources and proprietary, third-party providers. With the
exception of self-reported data which Metromail obtains primarily through the
use of consumer surveys, Metromail does not collect data directly from
consumers. Among the publicly available sources used by Metromail are the
"white pages" (Metromail's primary source of names, addresses and telephone
numbers), public records of driver's license registrations, real estate
transactions and U.S. census data. Metromail has arrangements with numerous
third parties that provide proprietary data to Metromail. These providers
include certain of Metromail's clients that provide Metromail with data
relating to their recent direct marketing experiences.
 
  In 1993, Metromail began collecting data directly from consumers in response
to surveys. Metromail distributes to consumers, primarily through co-op
mailings, package inserts and magazine inserts, survey questionnaires in
various forms. These questionnaires solicit information from the recipients
such as standard demographic information, product preferences, purchasing
habits, activities, hobbies and interests, brand awareness and medical
ailments. Questionnaires can be tailored to address specific marketing
concerns of Metromail's clients by developing specific survey questions which
seek the desired information. Survey respondents complete and return
questionnaires to Metromail because they become eligible to receive offers of
coupons, samples and information from manufacturers, pharmaceutical companies,
financial institutions and other service providers. Incentives such as
sweepstakes offers, prizes and extensions to subscribed services are also
provided when appropriate to increase response rates. Metromail provides
disclosure to potential survey respondents regarding the intended use of the
data thereby reducing privacy concerns because respondents are voluntarily
completing the surveys acknowledging that they understand how the information
may be used. Metromail does not use the information collected through surveys
for its reference services and has stated that it will not do so unless
disclosure is provided in the survey regarding the use of such information for
reference services. Metromail expects to continue to expand its use of surveys
as a data collection method. As indicated above under "International
Operations," Metromail is using the survey method as a means to develop its
database in the United Kingdom.
 
  Metromail is dedicated to being a leader in ethical management of consumer
data. It has developed information management practices applicable to its
direct marketing services and its reference services. Metromail believes that
responsible data management includes collecting, using and disseminating
information by fair, ethical and lawful means and respecting the requests of
individuals for information Metromail possesses about them and any requests
that their names be suppressed in Metromail's database so that they do not
receive unwanted marketing solicitations.
 
COMPETITION
 
  The markets in which Metromail competes are highly competitive and
fragmented. While a number of large companies and many smaller competitors
provide certain of the direct marketing, database marketing and reference
services provided by Metromail, Metromail believes that it provides the
broadest range of these types of services of any company in the direct
marketing services, database marketing services and reference services
industries.
 
  In list development and list enhancement services, Metromail competes on the
basis of the quality, accuracy and completeness of its database, its market
analysis and segmentation capabilities and the other list enhancement services
it offers. Metromail competes in marketing database services on the basis of
the quality of its software products. Metromail competes in lettershop
services on the basis of the capabilities and efficiencies of its equipment
and employees, which enable it to handle large and complicated orders in a
timely manner. Price is also a competitive factor for all the direct marketing
services Metromail provides. In reference services, Metromail competes on the
basis of the quality, accuracy and scope of the information contained in its
database,
 
                                      59
<PAGE>
 
the quality of its customer service and price. With respect to its on-line
services, two critical competitive factors are the ability to be contacted by
the user and the response time.
 
REGULATION
 
  Although the manner in which Metromail collects, uses and transfers certain
types of data is regulated in certain respects at the federal level and by
certain states, as described below, Metromail's business is not currently
subject to direct regulation by any government agency, other than regulations
applicable to businesses generally, including regulations concerning the
environment.
 
  In response to concerns about individual privacy and the collection,
distribution and use of information about individuals, the Direct Marketing
Association (the "DMA"), which is the leading trade association of direct
marketers, has established certain guidelines for fair information practices
which it recommends be followed by participants in the direct marketing
industry. Metromail was actively involved in the formulation of the DMA's
guidelines, and many of Metromail's significant direct marketing clients have
adopted and implemented such guidelines. In addition, Metromail has adopted
and is implementing information management practices, principles and
procedures which supplement those of the DMA. One of the guidelines suggested
by the DMA is that direct marketers refrain from soliciting by mail or
telephone those individuals who have contacted the DMA and have asked that
they not be the subject of unrequested solicitations. To make compliance with
this guideline possible, the DMA maintains the Mail Preference Service and the
Telephone Preference Service, consisting of lists of those individuals who
have notified the DMA that they wish to "opt out" of receiving mail or
telephone solicitations. The DMA makes these lists available to participants
in the direct marketing industry who subscribe to these services. Metromail is
a subscriber and receives updated lists from the DMA monthly and promptly
suppresses in its database all information concerning the individuals who
appear on the DMA lists.
 
  Privacy concerns have also led to increased federal and state regulation of
the collection, use and transfer of information about individuals and of
direct marketers and their activities. Examples of laws regulating the use of
information include laws adopted by a number of states precluding the use of
information derived from voter registration records, real estate files and
driver's licenses and the federal Driver's Privacy Protection Act of 1994,
which becomes effective in September 1997. Under this act, each state will be
prohibited from disclosing personal information contained in motor vehicle
department records for bulk use in surveys, marketing or solicitations, unless
the state has implemented a procedure whereby each driver has the opportunity
to prohibit such use of information about such driver. Examples of laws
regulating direct marketers and their activities include: state laws requiring
telemarketers to be bonded or registered; a Federal Trade Commission
regulation prohibiting telemarketers from making a call to a person who
previously has stated that he or she does not wish to receive a call made by
or on behalf of the seller whose goods or services are being offered; and
federal and state restrictions on the use by telemarketers of automatic
dialing and artificial voices or prerecorded messages.
 
  In March, 1997, a bill seeking to restrict the sale of data was introduced
in the United States Congress. The Children's Privacy Protection and Parental
Empowerment Act seeks to prohibit list brokers (including Metromail) from
knowingly selling or purchasing personal information (defined to include name,
address and telephone number) about a child (defined to be a person under 16
years old) without the written consent of a parent of that child. A similar
version of this bill was introduced in the United States Congress in 1996 but
was not enacted into law.
 
  In 1996, Congress asked the Federal Reserve Board (the "FRB") to examine the
availability to the general public of sensitive consumer identification
information, including social security numbers, mother's maiden names, prior
addresses and dates of birth. The FRB invited companies to respond to
questions relating to the collection, maintenance and use of sensitive data.
In March, 1997, the FRB published its findings that (i) there is little hard
evidence on how fraud due to the usage of sensitive data occurs, the frequency
with which it occurs or the amounts of associated losses and (ii) at the
present time, losses attributed to identity theft do not appear to pose a
significant risk to insured depository institutions.
 
                                      60
<PAGE>
 
  The Federal Trade Commission (the "FTC") continues to conduct workshops and
studies on the protection and use of personal information. These workshops and
studies examine the collection and availability of personal information on the
Internet and on "look-up" services and the collection and availability of
children's information. Metromail has been actively working with the FTC on
these and other issues. FTC Commissioners have stated publicly that they
prefer industry self-regulation over government regulations.
 
  Because of the possibility of increased regulation brought on by privacy
concerns, Metromail collects certain data directly from individuals, who agree
that their information may be used for direct marketing and other purposes.
Although Metromail intends to continue to pursue actively the collection of
self-reported data, the percentage of data in Metromail's current database
that constitutes self-reported data is small.
 
  Metromail is not aware of any generally accepted industry guidelines for the
use of information on individuals in connection with Metromail's reference
services. Metromail has adopted its own privacy principles for its reference
services.
 
  Certain of the reference services provided by Metromail to certain credit
card issuer associations and their member banks are subject to the Fair Credit
Reporting Act ("FCRA"). Amendments to the FCRA, scheduled to become effective
on September 30, 1997, provide consumers with easier access to their credit
reports, facilitate the correction of errors in reports and address the issue
of "prescreening," a procedure used by creditors in some direct marketing
programs.
 
CUSTOMERS AND SEASONALITY
 
  Metromail's business is based on long-standing client relationships.
Although sales are not guaranteed under long-term contracts, a substantial
portion of Metromail's net sales is derived from clients that Metromail has
served for many years. Net sales to the top 25 clients (almost all of which
have been clients for five or more years) amounted to $65.9 million in 1994,
$68.6 million in 1995 and $75.4 million in 1996. Net sales to the top 25
clients accounted for 33.7%, 28.9% and 26.8% of total net sales in 1994, 1995
and 1996, respectively, as Metromail expanded into new products and services
across all operations. No single client accounted for more than 10% of total
net sales in any of these years.
 
  Metromail's business is somewhat seasonal with the majority of Metromail's
net sales and earnings from operations historically occurring in the second
half of a year. Furthermore, in 1997, Metromail's U.K. operations will
distribute only one survey (in the third quarter 1997) compared to two in 1996
(second quarter and fourth quarter 1996), reflecting the new nine month
production cycle for this portion of the U.K. operation's business. See "--
Management's Discussion and Analysis of Financial Condition and Results of
Operations--Outlook".
 
COMPUTER OPERATIONS
 
  Metromail's data centers run on computer systems designed to provide
advanced processing capabilities, provide flexibility to meet Metromail's and
its clients' changing needs and contain costs. Metromail's mainframe computer
system consists of two IBM ES9000 computers, one located at the Lombard data
center and one located at the Lincoln data center. The IBM ES9000 computer
located at the Lincoln data center has 223 MIPS (millions of instructions per
second) of processing power and the IBM ES9000 located at the Lombard data
center has 270 MIPS of processing power. The ES9000 platform allows for
expansion of processing capacity to approximately 3,000 MIPS, without
significant infrastructure changes. Other data center components include
robotic tape subsystems, DASD and high-speed laser, LED and compact printers.
Metromail also supports alternate platforms from IBM, Hewlett Packard and
Sequent, which have approximately a terabyte of DASD attached to them.
 
  In 1996, Metromail completed a major redesign of the file structure of its
database. This redesign, which commenced in 1994, takes advantage of new
relational software and parallel processing hardware technology. The new
database structure is expected to reduce the costs and time of adding newly
acquired data to the database, permit concurrent processing of a number of
separate jobs and reduce processing times.
 
EMPLOYEES
 
  As of December 31, 1996, Metromail had approximately 3,080 employees, of
whom approximately 2,975 were located in the United States and approximately
105 were located in the United Kingdom. The domestic employees included
approximately 275 officers and managerial employees, approximately 275
employees
 
                                      61
<PAGE>
 
engaged in sales or sales support and approximately 210 programmers, system
engineers and systems analysts. The domestic employees also include
approximately 1,360 hourly employees, most of whom are engaged in providing
lettershop services. Metromail employs part-time workers as needed, primarily
in lettershop services.
 
  None of Metromail's employees is covered by a collective bargaining
agreement. Metromail believes that its relations with its employees are good.
 
FACILITIES
 
  Metromail's principal executive offices and one of Metromail's data centers
are located in Lombard, Illinois, where Metromail leases a 115,000 square foot
facility pursuant to a lease expiring in 2001 and a 19,000 square foot
facility pursuant to a lease expiring in 2000. Metromail also owns a 233,000
square foot facility in Lincoln, Nebraska, which includes Metromail's second
data center, and lettershop facilities in Mt. Pleasant, Iowa (211,000 square
feet); Seward, Nebraska (161,000 square feet); and Rutland, Vermont (113,000
square feet). Metromail leases its 31 regional sales offices pursuant to
leases that in general have three-year terms. Metromail's marketing database
services operate from a 54,000 square foot leased facility in the Denver,
Colorado area.
 
LEGAL PROCEEDINGS
 
  In 1993, Metromail purchased the assets of Computerized Marketing
Technologies, Inc. and affiliated companies ("CMT") relating to a database
created through the use of questionnaires distributed to consumers. Following
this purchase, Metromail continued CMT's practice of contracting with
Computerized Image & Data Systems, Inc. ("CIDS") for CIDS to provide data
input services with respect to completed surveys. CIDS had been subcontracting
a portion of these services to a correctional facility maintained by the State
of Texas. This facility was a major supplier of data input services to the
State of Texas, including services with respect to voter registration and
drivers' license records, and according to CIDS, was selected as a
subcontractor, in part, because of the procedures followed by the facility to
safeguard the information made available to the prisoners. In June 1994,
Metromail became aware of a report that a woman in Ohio, who apparently had
completed a company survey, had received a letter purporting to contain
sexually explicit language from a convicted rapist held in the facility that
provided data input services. Immediately after becoming aware of this report,
Metromail requested the third party to terminate its subcontract with the
facility. On April 18, 1996, a complaint was filed in the District Court of
Travis County, Texas (Beverly J. Dennis v. Metromail Corporation et al., Cause
No. 96-04451) against Metromail, R. R. Donnelley, CIDS, the Texas Department
of Criminal Justice, the executive director of the Texas Department of
Criminal Justice and the chairman of the Texas Board of Criminal Justice by
the woman who allegedly had received the letter. The complaint alleges the
following causes of action against Metromail and R. R. Donnelley and certain
of the other defendants: (1) defendants' conduct represented an intentional or
reckless disregard of plaintiffs' safety; (2) the conduct of Metromail, R. R.
Donnelley and CIDS in inducing plaintiffs to provide information without
disclosing to plaintiffs that such information would be provided to convicted
felons constituted fraud; (3) defendants have been unjustly enriched by their
actions; (4) defendants' conduct resulted in the invasion of plaintiffs'
privacy; (5) defendants' conduct resulted in the infliction of severe
emotional distress upon plaintiffs; and (6) defendants were grossly negligent
in entrusting plaintiffs' information to convicted felons. In addition, the
complaint alleged two causes of action solely against the Texas Department of
Criminal Justice and the two state officials. The complaint seeks restitution,
actual and exemplary damages in an unspecified amount and injunctive relief on
behalf of the named plaintiff and a purported class consisting of all persons
who completed Company surveys and whose completed surveys were processed by
inmates in the Texas prison system from January 1, 1993 to the present time.
Metromail is not yet able to determine the number of persons comprising the
purported class but believes the number of persons who completed surveys in
this period and whose surveys were processed by such inmates could exceed 1.3
million. In April, 1997, the Court dismissed the complaints against the Texas
Department of Criminal Justice, the executive director of the Texas Department
of Criminal Justice and the chairman of the Texas Board of Criminal Justice.
In addition, in April, 1997, a third amended complaint was filed naming three
additional plaintiffs, none of whom alleged that he or she received any
offensive letter from a prisoner that key punched data. Metromail does not
anticipate that the developments of April, 1997 will have any adverse impact
on the outcome of this suit.

  Metromail intends to defend vigorously this suit. Metromail had removed the
case to the United States District Court for the Western District of Texas but
the case was subsequently remanded to state court. Metromail has filed a
motion to dismiss all counts against it. If the motion is not granted,
Metromail intends to challenge certification of the class, and Metromail
believes that if such challenge is successful, this litigation would not have
a material adverse effect on Metromail. However, because this litigation is in
its early stages, it is not possible to make a meaningful determination of the
ultimate outcome or to make an estimate of the loss, if any, should the
outcome be unfavorable. Metromail has made a preliminary estimate that its
costs of litigating the case will be $1.5 million. Metromail's insurer has
agreed to assume the defense of this case subject to a reservation of rights
to deny coverage. In the event Metromail's insurer were to successfully deny
coverage, R. R. Donnelley has agreed to pay the legal fees and expenses
incurred by Metromail in defending this case, but Metromail would be
responsible for any other amounts payable by it as a result of this case.
Because of such agreements to pay such fees and expenses, such legal fees and
expenses will not affect Metromail's cash flows; however, if R. R. Donnelley
were to pay such fees and expenses, applicable accounting principles would
require Metromail to recognize such fees and expenses as incurred and apply
all payments by R. R. Donnelley in respect of such fees and expenses to
additional paid-in capital.
 
  Metromail is subject to various claims and legal actions which arise in the
ordinary course of business. Metromail believes such claims and legal actions,
individually and in the aggregate, will not have a material adverse effect on
the business or financial condition of Metromail.
 
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
 Three months ended March 31, 1997 compared to the three months ended March
31, 1996
 
  Total net sales increased 21.0% to $65.8 million for the first quarter of
1997 from $54.4 million for the first quarter of 1996. This $11.4 million
increase was comprised of an $8.2 million, or 30.3%, increase in direct
marketing sales, a $1.6 million, or 10.9%, increase in database marketing
sales and a $1.6 million, or 13.1%, increase in reference sales. Within direct
marketing services, list services in the U.S. and U.K., as well as lettershop
services, all produced double digit growth over the prior year first quarter.
Sales growth for database marketing services, which includes software sales
and list enhancement services, resulted primarily from strong demand for
Metromail's AnalytiX and Explore software products. The growth in reference
sales was primarily due to a 30.4% increase in Metromail's MetroNet and
National Directory Assistance ("NDA") on-line services along with 2.5% growth
in the directory business.
 
  Database and production costs primarily represent expenses incurred to
maintain Metromail's database and to customize data for client use, including
salaries and wages, annual costs to acquire data and amortization of
capitalized data costs, facility costs and depreciation of equipment. Database
and production costs increased for the three months ended March 31, 1997 to
$41.2 million, or 62.6% as a percentage of total net sales, from $33.6 million
for the three months ended March 31, 1996, or 61.8% as a percentage of total
net sales. Approximately $3.1 million of the increase was due to increased
volume in the lettershops, increased staffing and facility costs to support
the growth of Metromail's software business and online services. Increased
salary costs across all operations accounted for the balance of the increase.
The increase as a percentage of total net sales was primarily due to the
increased costs incurred for the higher than planned volume at the
lettershops, which have higher production costs as a percentage of total net
sales compared to the other operations of Metromail.
 
  Selling expense of $12.8 million increased $1.0 million, or 8.5%, from the
three months ended March 31, 1996, and decreased as a percentage of total net
sales to 19.5% from 21.7% in the prior year period. The improvement in selling
expense as a percentage of total net sales was due to increased efficiencies
across the sales organizations.
 
  General and administrative expenses increased $1.1 million, or 22.7%, from
the three months ended March 31, 1996 primarily due to increased staff costs
associated with being a stand alone public company. None of these costs were
incurred in the first quarter of 1996.
 
                                      63
<PAGE>
 
  Earnings from operations of $3.4 million increased $1.7 million for the
three months ended March 31, 1997 from $1.7 million for the three months ended
March 31, 1996 due to the foregoing factors.
 
  Interest expense-related party, primarily paid to a subsidiary of R. R.
Donnelley, of $5.3 million for the three months ended March 31, 1996, was zero
for the three months ended March 31, 1997 due to the elimination of the
related party debt subsequent to completion of the IPO.
 
  Metromail's tax expense increased $2.7 million compared to the first quarter
of 1996 due to the increase in earnings before income taxes. The effective tax
rate exceeds the U.S. federal statutory rate primarily due to the effect of
non-deductible goodwill amortization.
 
  Net income increased $4.2 to $1.3 million compared to a $2.9 million loss
for the first quarter of 1996 as a result of the foregoing factors.
 
 Year ended December 31, 1996 compared to the year ended December 31, 1995
 
  Total net sales increased 18.7% to $281.4 million for 1996 from $237.2
million for 1995. This $44.2 million increase resulted from a $28.5 million,
or 23.3%, increase in direct marketing sales, an $8.8 million, or 13.1%,
increase in database marketing sales and a $6.9 million, or 14.6%, increase in
reference sales. Direct marketing sales growth was due to $17.7 million of
additional sales of U.K. business due to growth, completion by ICD of two
surveys in 1996 compared to one in 1995 and the inclusion of a full twelve
months of sales of ICD (acquired in May 1995). Additional direct marketing
growth was due to increased lettershop volume of $3.7 million and more modest
increases across the traditional direct marketing services of list and U.S.
survey. Database marketing sales growth was due to strong demand for the
AnalytiX and Explore database products. Reference services sales growth was
primarily due to a 28.7% increase in Metromail's MetroNet and NDA on-line
services plus a 5.8% increase in directory publishing services.
 
  Database and production costs increased from $134.4 million for 1995, or
56.7% as a percentage of total net sales, to $155.7 million, or 55.3% as a
percentage of total net sales, for 1996. This growth was due to increased
expenses of $4.9 million related to the second U.K. survey, start-up costs of
the NDA on-line services of $5.7 million, increased production costs to
support the higher sales volume for the lettershops, increased costs to
support the growth in marketing database services, increased U.S. survey
expenses, expenses related to the upgrade of computer capacity and increased
directory publishing costs. The decrease in the database and production costs
as a percentage of total net sales was due to improved efficiencies at ICD
(primarily the second survey, which has production costs as a percentage of
total net sales less than Metromail's other operations) and increased sales in
the traditional direct marketing areas, which improved the coverage of fixed
costs. The decrease in database and production costs as a percentage of total
net sales was partially offset by increased costs related to the start up of
the NDA on-line services.
 
  Selling expense increased $7.3 million, or 16.0%, from 1995 and decreased as
a percentage of total net sales from 19.4% for 1995 to 18.9% for 1996. The
increase in the amount is due to the increase in sales and related selling
expenses across all operations and from ICD, where selling expenses as a
percentage of total net sales are higher than Metromail's other operations.
 
  General and administrative expenses grew $8.9 million, or 53.3%, from 1995
and as a percentage of total net sales from 7.0% to 9.1% for 1996. The
increase resulted primarily from the acquisition and growth of ICD, and
increased staff costs associated with being a stand alone public company.
 
  Earnings from operations of $37.3 million for 1996 increased $6.7 million
from $30.6 million for 1995 due to the foregoing factors.
 
  Interest expense-related party decreased $11.1 million due to the use of the
IPO net proceeds to repay the amount owed to a subsidiary of R. R. Donnelley.
 
                                      64
<PAGE>
 
  Interest expense of $0.8 million resulted from borrowings under a credit
agreement with a syndicate of banks (See "--Changes in Financial Condition")
required to pay related party debt for ICD and provide operating funds in the
U.K.
 
  Metromail's tax expense in 1996 increased $6.1 million compared to 1995 due
to the increase in earnings before income taxes. The effective tax rate
exceeds the U.S. federal statutory rate primarily due to the effect of non-
deductible goodwill amortization.
 
  Net income increased $11.2 million to $13.9 million for 1996 as a result of
the foregoing factors.
 
 Year ended December 31, 1995 compared to the year ended December 31, 1994
 
  Total net sales increased 21.3% to $237.2 million in 1995 from $195.5
million in 1994. This $41.7 million increase was comprised of a $22.2 million,
or 22.2%, increase in direct marketing sales, a $10.7 million, or 18.9%,
increase in database marketing sales and a $8.8 million, or 22.7%, increase in
reference sales. Direct marketing sales growth resulted primarily from strong
demand for list development and lettershop services. List development sales
increased $10.2 million due to growth of 8.1% in sales to national list
accounts, 12.7% in sales to small business accounts and 51.9% in sales of the
BehaviorBank list product. Lettershop sales increased $4.2 million due to
increased sales efforts to utilize available capacity. Direct marketing sales
were also increased by $7.1 million due to the inclusion of ICD's sales
following the acquisition of ICD in May 1995. Database marketing growth
included $9.5 million reflecting a full year's sales after the June 1994
acquisition of CIC along with volume growth of 35.8% over comparable full year
1994 sales. The increase in reference sales reflected in large part the strong
growth in on-line services, including the NDA and MetroNet services.
 
  Database and production costs increased in 1995 to $134.4 million, or 56.7%
as a percentage of total net sales, from $108.8 million in 1994, or 55.7% as a
percentage of total net sales, primarily due to the start-up of the NDA
service, along with increased expenses to upgrade computers resulting in
increased capacity.
 
  Amortization of goodwill increased 12.7% to $7.4 million in 1995. This
increase reflected the inclusion of a full year of amortization of goodwill
resulting from the CIC acquisition and additional goodwill resulting from the
ICD acquisition.
 
  Selling expenses increased $8.8 million, or 23.7%, from 1994 and as a
percentage of total net sales to 19.4% in 1995 from 19.0% in 1994. The
increase in selling expenses was due to the inclusion of CIC for a full year
($3.1 million), the acquisition of ICD ($1.5 million) and growth in the on-
line services sales staff ($0.7 million), as well as increased commissions and
support costs across all businesses due to increased sales. The increase in
selling expenses as a percentage of total net sales resulted primarily from
the fact that selling expenses of CIC and ICD as a percentage of their total
net sales was higher than for Metromail's other operations.
 
  General and administrative expenses grew $2.2 million, or 15.5%, from 1994,
but decreased as a percentage of total net sales from 7.4% to 7.0% in 1995.
The increase in these expenses resulted from the acquisition of ICD ($1.4
million), the settlement agreement with Aristotle Industries, Inc. regarding a
contract dispute ($0.7 million) and the inclusion of CIC for a full year ($0.6
million), as well as increased expenses across Metromail's other operations.
 
  Provisions for doubtful accounts increased $0.3 million, or 18.0%, from
1994, but remained the same as a percentage of total net sales at 0.9%.
 
  Interest expense, primarily paid to a subsidiary of R. R. Donnelley,
increased by $2.3 million because Metromail had higher average outstanding
debt levels in 1995. The higher debt levels were required to fund capital
expenditures, the ICD acquisition and increased working capital requirements
to support sales increases.
 
  Metromail's effective income tax rate decreased to 70.7% in 1995 from 74.1%
in 1994. The effective tax rate exceeds the U.S. federal statutory rate due to
the effect of nondeductible goodwill amortization and of state and foreign
taxes. The decrease in the effective tax rate in 1995 reflects the increase in
pretax income, which reduces the relative effect of the nondeductible items.
 
                                      65
<PAGE>
 
  Net income increased $0.7 million, or 37.6%, to $2.7 million in 1995 as a
result of the foregoing factors.
 
 Changes in Financial Condition
 
  For the first three months of 1997, operating cash flow (net income plus
depreciation and amortization) of $8.8 million increased $6.2 million over the
prior year period. For 1996, operating cash flow of $42.2 million increased
$18.6 million from 1995. Metromail believes that cash flows from operations
will be sufficient to fund its on-going operations on a long-term basis, as
well as continued growth and investment. Metromail expects the credit
agreement described below to be available for seasonal cash needs and
acquisitions.
 
  Capital expenditures and investments for the first three months of 1997
totaled $9.7 million, an increase of $1.8 million over the first three months
of 1996, primarily due to a minority investment in a provider of database
marketing and direct marketing services. Capital expenditures for 1996 totaled
$37.6 million, an increase of $9.1 million over the prior year. The increase
was due to funding for the second U.K. survey, database redesign, data center
expansion and various administrative software packages required as a stand
alone public company.
 
  Metromail has entered into a credit agreement with a syndicate of banks (the
"Credit Agreement") under which it is entitled to borrow up to $45 million on
a revolving credit basis. Borrowings under the Credit Agreement mature in 2001
and bear interest (i) at the prime rate announced by the bank acting as Agent
for the syndicate, (ii) at the LIBOR rate plus, depending on Metromail's
leverage ratio and fixed charge coverage ratio, up to 42.5 basis points per
annum, or (iii) at a rate determined by competitive bidding. At March 31, 1997
there was $21.0 million outstanding under the credit agreement resulting from
the repayment of related party debt and borrowings to provide operating funds
for Metromail's U.K. operations.
 
  Under the terms of a stock repurchase program approved by the Board of
Directors in December 1996, Metromail repurchased 54,800 shares of Common
Stock for $1.0 million during the three months ended March 31, 1997 and
125,100 shares of Common Stock for $2.1 million in 1996.
 
 Outlook
 
  Historically, Metromail's net sales build quarterly through the year, with
the majority of net sales being achieved in the second half of a given year.
In 1994, 1995 and 1996 total net sales of Metromail during the second half of
the year constituted 56.3%, 55.3% and 56.0%, respectively, of the total net
sales for the year.
 
  Many of Metromail's expenses are incurred ratably through the year and, when
combined with the quarterly revenue pattern discussed above, result
historically in fluctuations in earnings from operations for the year.
Earnings from operations are strongest in the second half of the year.
Earnings from operations in the second half of 1994, 1995 and 1996 constituted
70.4%, 55.6% and 72.0%, respectively, of total earnings from operations for
the year. Had the deferral of approximately $2.0 million of expenses from the
second quarter of 1995 to the third and fourth quarters of 1995 (resulting in
a $2.0 million negative impact on earnings from operations for the second half
of 1995) not taken place, Metromail estimates that the percentage of earnings
for the second half of 1995 would have been approximately 62.1% of the full
year's earnings from operations.
 
  Management of Metromail expects the historical patterns of larger second
half portions of the year's sales and operating earnings to occur again in
1997. Furthermore, in 1997, the U.K. operations will distribute only one
survey (in the third quarter 1997) compared to two in 1996 (second quarter and
fourth quarter 1996) reflecting the new nine month production cycle for this
portion of the U.K. operation's business. The 1996 surveys produced $7.4
million and $9.8 million of revenue in the second and fourth quarters of 1996,
respectively. The second and fourth quarters of 1997 will not include any U.K.
survey revenue. In 1997 the U.K. survey revenue will be reflected in
Metromail's results in the third quarter. Revenues in 1998 are expected to
include two surveys for Metromail's U.K. operations.
 
  Metromail is required to adopt Statement of Financial Accounting Standards
(SFAS) No. 128 on Earnings per Share and SFAS No. 129 on Capital Structure for
both interim and annual periods ending after December 15, 1997. Earlier
adoption is prohibited. The impact of the adoption of these standards is not
expected to be material to Metromail's financial statements.

                   ADDITIONAL INFORMATION REGARDING ATLANTES
 
                            DESCRIPTION OF BUSINESS
 
  Since its formation as a Colorado corporation in late 1991, Atlantes has
become one of the leading consumer database development companies in the
United States. Currently working with over 170 corporations ("clients")
including many well known U.S. corporations, Atlantes obtains information from
product registration questionnaires, warranty questionnaires, and other
questionnaires related to the purchase of consumer products. Atlantes manages
the process of computerizing these questionnaires through third party data
entry vendors and creates and maintains databases using proprietary PC based
database management systems. These systems enable clients to obtain valuable
information about, and provide clients access to, their consumers. This
information contains not only product related information, but also certain
demographic and behavioral information important to the client and to
Atlantes.
 
  In return for these services, Atlantes receives ownership of certain
information, including the consumer's name, address, demographic and
behavioral information. This data is then sold in the form of targeted mailing
lists to direct marketers throughout the United States. Currently, this data
is marketed by a third party, Experian, which has an exclusive contract with
Atlantes to market Atlantes' database. Experian sublicenses the Atlantes'
database to third party resellers, of which Metromail is the leading reseller
of such data.
 
  Initially, Atlantes intended to develop its own list sales organization to
market its database and, in 1994, attempted to do this. However, Atlantes
determined in late 1994 that the time and expense involved would require
substantial additional working capital and began exploring strategic alliances
with other companies within the direct marketing industry. On December 23,
1994, Atlantes entered into an agreement with Experian, Inc. (formerly the
Target Marketing Services division of TRW, Inc.) whereby Experian was given
the exclusive right to market Atlantes' database through December 31, 1999.
Pursuant to this agreement, Atlantes receives a fee for each record sent to
Experian, plus 50% of the list sales revenue generated by Experian from sales
of data from Atlantes' database. Revenue from Experian under this agreement
totaled approximately 75%, 78% and 86% of total revenues of Atlantes for 1994,
1995 and 1996, respectively.
 
  Atlantes competes in the consumer database management industry. Access to
demographic and behavioral data enables direct marketers to fine tune their
screening of the database for attributes which make the recipient of the
direct marketing solicitation more likely to respond. This screening and the
ability to target more likely buyers becomes more and more important to direct
mail advertisers as the costs of the mailing (design, paper, printing,
postage, and handling) increase.
 
  A number of other companies collect consumer data for sale to third parties,
but Atlantes differentiates itself by collecting demographic and behavioral
information on the consumer directly from product registration questionnaires
filled out by the consumer, where the consumer is informed that the data
provided may be used for direct marketing purposes unless the consumer
otherwise indicates. The only other known competitor to compete in this niche
is R.L. Polk & Company ("Polk"), through the division formerly known as
National Demographics and Lifestyles ("NDL"). Founded in 1975, NDL was
acquired by Polk in 1988 and is well established in the marketplace. Atlantes
has had to overcome its relative newness to the market, its smaller size, its
limited financial resources, and the fact that initially, few companies were
utilizing Atlantes' database management services. These factors have limited,
to a certain extent, Atlantes' ability to market to the larger manufacturers
of durable goods.
 
  Although both companies use self-reported data, Atlantes differentiates
itself from Polk by collecting its data on a short questionnaire format. A
typical Atlantes designed questionnaire will include seven to ten behavioral
and demographics questions in addition to the general consumer and product
information. Questions found on a short questionnaire typically include
requests for information regarding the consumer's income level, education
level, recent purchases and family size. In contrast, Polk's questionnaires
will typically contain approximately 20-25 life style and demographics related
questions. The long questionnaire format contains much more information about
the habits and demographics of a consumer. However, the length of the
questionnaire increases the total printing costs, may lower response rates
from the consumers, increases the cost of keying the data into a computer,
slows the time it takes to prepare the data for sale and delays the response
to client information requests.

<PAGE>
 
  Atlantes has enjoyed strong database growth with the addition of 4.26
million, 6.14 million, and 8.23 million records during the years ended
December 31, 1994, 1995 and 1996, respectively, and with the addition of 2.80
million records during the three month period ended March 31, 1997. Atlantes'
client base is well diversified, with no single client generating more than
5.2% of Atlantes' annual questionnaire flow. Moreover, Atlantes also enjoys a
broad industry diversification, with nine separate industries, each
representing at least 7% of Atlantes' annual questionnaire flow.
 
  Atlantes' senior management team has broad experience with over 50 years of
combined work experience in the direct marketing industry. Atlantes now
employs 13 people on a full-time basis.
 
  Despite having strong growth in its clients and questionnaire flow, Atlantes
has generated net losses of $573,377, $519,324 and $294,112 on revenues of
$1,000,461, $1,167,185 and $1,834,765 for the years ended December 31, 1994,
1995 and 1996, respectively. For the three months ended March 31, 1997,
Atlantes has generated net income of $54,489 on revenue of $672,548. See "--
Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "ATLANTES FINANCIAL STATEMENTS."

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS
 
GENERAL
 
  Atlantes has developed a proprietary computer database which accumulates and
provides access to consumer product purchasing information. Atlantes provides
consumer database management services, primarily to durable goods
manufacturers, in exchange for consumer product purchasing information and the
right to sell selected parts of the consumer database, in the form of customer
lists, to the direct marketing industry. Atlantes also provides consumer
database and information design to its clients.
 
  In December 1994, Atlantes entered into an exclusive arrangement with
Experian giving Experian the exclusive right to market Atlantes' database
through December 31, 1999. Direct marketing sales to Experian accounted for
approximately 75%, 78%, 86% and 91% of Atlantes' revenues for the years ended
December 31, 1994, 1995 and 1996 and the three months ended March 31, 1997,
respectively
 
RESULTS OF OPERATIONS
 
 Three months ended March 31, 1996 and 1997
 
  Direct Marketing Sales. Direct marketing sales for the three months ended
March 31, 1997 were $672,548 compared with $356,353 for the same period in
1996. Data sales to Experian increased 44% to $380,769 for the three months
ended March 31, 1997 compared to $265,218 for the three months ended March 31,
1996, due to database growth, expansion of types of data sold and an increase
in the contracted base price per record. Direct marketing list sales increased
311% to $230,191 for the three months ended March 31, 1997 compared to $56,047
for the three months ended March 31, 1996, primarily due to two additional
distribution channels being added during 1996. Client service sales increased
88% to $60,431 for the three months ended March 31, 1997 from $32,083 for the
three months ended March 31, 1996 primarily due to growth in marketing
research services provided to Atlantes' database clients.
 
                                      70

  Database and Production Costs. Database and production costs were $221,490
for the three months ended March 31, 1997, compared to $167,285 for the same
period for 1996. The increase was due primarily to a 67% increase in database
records processed to 2.80 million for the three months ended March 31, 1997
from 1.68 million for the same period in 1996.
 
  General and Administrative Expenses. General and administrative expenses
were $392,652 for the three months ended March 31, 1997, compared to $285,838
for the same period in 1996. The increase was primarily due to increased
expenses in the areas of salaries and salary related costs of personnel
engaged in administrative functions, and client services and costs such as
rent, insurance, telephone, legal, postage, depreciation, financing and merger
and acquisition costs.
 
  Interest Expense. Interest expense increased to $3,917 for the three months
ended March 31, 1997 from $0 for the same period in 1996 primarily due to a
borrowing on a revolving line of credit that Atlantes entered into in March
1997.
 
 Year Ended December 31, 1996 Compared to Year Ended December 31, 1995
 
  Direct Marketing Sales. Direct marketing sales for the year ended December
31, 1996, were $1,834,765 compared with $1,167,185 for the same period in
1995. A major component of the increase was an increase in data sales to
Experian which increased 57% to $1,219,453 in 1996 compared to $775,728 in
1995 due to database growth, expansion of types of data sold and an increase
in the contracted base price per record. Direct marketing list sales increased
82% to $370,813 in 1996 compared to $203,543 in 1995 primarily due to two
additional distribution channels being added during 1996. Client service sales
increased 45% to $233,865 from $161,248 primarily due to growth in marketing
research services provided to Atlantes' database clients.
 
  Database and Production Costs. Database and production costs were $748,747
for the year ended December 31, 1996 compared to $565,942 for the same period
for 1995. The increase was due primarily to a 34% increase in database records
processed to 8.23 million for the year ended December 31, 1996 from 6.14
million for the same period in 1995.
 
  General and Administrative Expenses. General and administrative expenses
were $1,380,130 for the year ended December, 31, 1996, compared to $1,116,297
for the same period in 1995. The increase was primarily due to increased
expenses in the areas of salaries and salary related costs of personnel
engaged in administrative functions, and client services and costs such as
rent, insurance, telephone, legal, postage, depreciation, and travel and
entertainment.
 
  Interest Expense. Interest expense decreased to $0 for the year ended
December 31, 1996 from $4,270 for the same period in 1995 as the interest
bearing short-term notes outstanding at December 31, 1994 were converted to
equity in the first quarter 1995 and Atlantes had no additional borrowings in
1995 and 1996.
 
 Year Ended December 31, 1995 Compared to Year Ended December 31, 1994
 
  Direct Marketing Sales. Direct marketing sales for the year ended December
31, 1995 were $1,167,185 compared with $1,000,461 for the same period in 1994.
Data sales to Experian increased 6% to $775,728 in 1995 compared to $734,306
in 1994 due to database growth. Direct marketing list sales increased 66% to
$203,543 in 1995 compared to $122,668 in 1994 primarily as a result of
increased marketing efforts of Atlantes' database. Client service sales
increased 25% to $161,248 from $128,845 as Atlantes began providing marketing
research services to its database clients.
 
  Database and Production Costs. Database and production costs were $565,942
for the year ended December 31, 1995 compared to $455,285 for the same period
for 1994. The increase was due primarily to a 44% increase in database records
processed to 6.14 million for the year ended December 31, 1995 compared to
4.26 million for the same period in 1994. The additional volume allowed
Atlantes to negotiate lower data entry pricing.
 
                                      71
<PAGE>
 
  General and Administrative Expenses. General and administrative expenses
were $1,116,297 for the year ended December, 31, 1995, compared to $952,283
for the same period in 1994. The increase was primarily due to increased
expenses in the areas of salaries and salary related costs of personnel
engaged in administrative functions, and client services and costs such as
rent, insurance, travel and entertainment and telephone costs.
 
  Interest Expense. Interest expense decreased to $4,270 for the year ended
December 31, 1995 from $166,270 for the same period in 1994 as the interest
bearing short-term notes outstanding at December 31, 1994 were converted to
equity in the first quarter 1995. In addition, in 1994, Atlantes incurred
interest expense related to the issuance of warrants in connection with the
extension of the maturities of the notes to shareholders.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since its inception in 1991, Atlantes has financed its activities through
the issuance of debt instruments, equity in private placement transactions and
revenue from direct marketing sales. From its inception in September 1991 to
March 31, 1997, Atlantes had received cash of approximately $1,716,000 from
debt and equity transactions, while sales in the same period were
approximately $4,800,000. At March 31, 1997, Atlantes had approximately
$204,000 in cash.
 
  Cash used in operations was $970,965 for the year ended December 31, 1994
compared to cash provided by operations of $259,882 for the year ended
December 31, 1995. The increase was primarily due to a decrease in accounts
receivable related to a payment of approximately $734,000 for initial services
provided to Experian in 1994. Cash used in Atlantes' operations was $161,587
for the year ended December 31, 1996 compared to cash provided by operations
of $259,882, for the year ended December 31, 1995. The increase in cash used
in Atlantes' operations in 1996 compared to 1995 was primarily due to the
increase in accounts receivable, as well as expansion of operations resulting
from increased sales. Cash provided by operations was $26,346 for the three
months ended March 31,1997 compared to cash used in operations of $82,519 for
the three months ended March 31, 1996. The decrease in cash used in Atlantes'
operations for the first quarter of 1997 compared to the first quarter of 1996
was primarily due to net income of $54,489 reported by Atlantes in the first
quarter 1997 compared to a net loss of $96,770 in the first quarter 1996.
Capital expenditures were primarily comprised of purchases of furniture and
fixtures and computer equipment. Capital expenditures were $39,161, $55,318
and $30,142 for the years ended December 31, 1994, 1995 and 1996,
respectively, and $13,663 and $12,509 for the three months ended March 31,
1996 and 1997, respectively.
 
  Since its inception in September 1991, Atlantes has recorded accumulated
losses of $1,917,742 and has working capital of $344,369 as of March 31, 1997.
While the timing and amount of capital requirements cannot be predicted with
certainty, Atlantes believes that cash on hand, available borrowings of
approximately $246,000 as of March 31, 1997 under its revolving line of credit
and funds generated from operations will be sufficient to meet its working
capital and capital expenditure requirements for at least the next 12 to 18
months. Thereafter, if Atlantes' operating plans change, Atlantes may be
required to raise additional sources of financing to support its operating and
financing needs. There can be no assurance that Atlantes will not be required
to raise additional funding sooner or that such additional funding, if needed,
will be available on terms attractive to Atlantes, or at all.

  We have audited the accompanying consolidated and combined balance sheets of
Metromail Corporation and Affiliates as of December 31, 1996 and 1995, and the
related consolidated and combined statements of operations, changes in
shareholders' equity and cash flows for each of the three years ended December
31, 1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these 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 audits 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 financial statements referred to above present fairly,
in all material respects, the financial position of Metromail Corporation and
Affiliates as of December 31, 1996 and 1995 and the results of its operations
and cash flows for each of the three years ended December 31, 1996, in
conformity with generally accepted accounting principles.

                     METROMAIL CORPORATION AND AFFILIATES
 
            NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND NATURE OF OPERATIONS
 
  Metromail Corporation ("Metromail" or the "Company") is a leading provider
of marketing-oriented consumer information and reference services which it
supplies to a wide variety of organizations engaged in direct mail, telephone
and target marketing, as well as to clients who need specific reference and
information services. The Company operates entirely within the information
services industry segment. Within this segment, the Company offers two general
categories of products and services: direct marketing services and reference
services.
 
  Metromail was a wholly owned subsidiary of R. R. Donnelley & Sons Company
("R. R. Donnelley") until June 19, 1996 when the Company completed an initial
public offering of 13.8 million shares of its common stock (the "IPO"),
reducing R. R. Donnelley's ownership in the Company to 38.4%. Metromail had
been acquired by R. R. Donnelley in 1987 in a business combination accounted
for as a purchase. On the date of acquisition, the financial position of
Metromail was adjusted to the fair value of the assets acquired and
liabilities assumed by R. R. Donnelley. All adjustments to Metromail's
financial position by R. R. Donnelley at the date of acquisition have been
pushed down to Metromail's financial statements.
 
  The accompanying consolidated and combined financial statements include the
accounts of Metromail and subsidiaries, as well as International Communication
& Data Plc ("CD") and Data by Design ("DBD"), which were affiliates of
Metromail in 1995. ICD was an affiliate of Metromail and an indirect wholly
owned subsidiary of R. R. Donnelley located in the United Kingdom. DBD was a
division of a wholly owned subsidiary of R. R. Donnelley located in the United
Kingdom, which was acquired by R. R. Donnelley in August 1994. ICD was
contributed to Metromail by R. R. Donnelley in February 1996. Subsequent to
this contribution, ICD purchased all of the assets of DBD. The accompanying
financial statements have been restated to reflect the combination of entities
under common control by R. R. Donnelley at December 31, 1995. ICD and DBD are
included in the results of operations of the accompanying consolidated and
combined financial statements from the date of original acquisition by R. R.
Donnelley in May 1995 and August 1994, respectively. Metromail, its wholly
owned subsidiaries, ICD and DBD are collectively referred to hereinafter as
the "Company".
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of Consolidation and Combination
 
  The consolidated and combined financial statements include all accounts of
the Company. All material intercompany balances and transactions are
eliminated in consolidation and combination.
 
 Revenue Recognition and Deferred Revenues
 
  The Company recognizes revenues for direct marketing services at the time
the services are provided. Revenues for reference services are recognized at
the time the service is provided or the product is delivered. The Company's
proprietary database software is generally licensed for an initial term of
three years. The license provides for an initial license fee, subsequent
annual license and maintenance fees and customer support service fees. Initial
license fee revenues are recognized when delivery of the software has
occurred, collectibility is probable and the Company retains no significant
obligations under the licensing agreements. Revenues from customer support
services are recognized in the period in which the support services are
performed by the Company. Annual license and maintenance fees are recognized
over the balance of the contract in accordance with specific contract terms.

                     METROMAIL CORPORATION AND AFFILIATES
 
     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
  The Company provides sales allowances for sales credits issued to clients in
the normal course of business. The allowances are recorded as reductions of
sales and are included in net sales in the accompanying statement of
operations. The reductions included in net sales were $3.6 million, $5.1
million and $5.0 million for the years ended 1994, 1995 and 1996,
respectively.
 
 Per Share Information
 
  Net income per share for the years ended December 31, 1996, 1995 and 1994
has been computed using the weighted average number of common stock and common
stock equivalents outstanding for the year ended December 31, 1996 which
reflects the shares issued by the Company upon completion of the IPO as if
they were outstanding for all years presented.
 
 Inventories
 
  Inventories include materials, labor and production overhead and are carried
at weighted average cost.
 
 Foreign Currency Translation
 
  The financial statements of ICD are translated into U.S. dollars using
exchange rates in effect at the end of the period for assets and liabilities
and average exchange rates for results of operations during the period of
inclusion in the Company's financial statements. Gains and losses arising from
translation are included in shareholders' equity and are not included in
results of operations.
 
 Property, Plant and Equipment--Capitalization and Depreciation
 
  Property, plant and equipment are stated at cost. Depreciation is computed
using the straight-line method based on useful lives of up to 30 years for
buildings and 3 to 10 years for machinery, equipment and computer hardware.
Maintenance and repair costs are charged to expense as incurred. When
properties are retired or disposed, the costs and related depreciation
reserves are eliminated and the resulting profit or loss is recognized in
income.
 
 Intangible Assets--Capitalization and Amortization
 
  Intangible assets primarily consist of the cost of databases and data,
internal software, software development and goodwill.
 
  Goodwill primarily consists of the excess of purchase price over the fair
market value of net assets acquired by R. R. Donnelley as a result of its
acquisition of Metromail in 1987. Goodwill also includes the excess of
purchase price over the fair market value of net assets for businesses the
Company has acquired and accounted for as a purchase. These costs are
amortized over their estimated useful lives of primarily 40 years.
 
  Costs incurred for routine maintenance and updating of databases are
expensed as incurred. However, the Company does capitalize the costs incurred
to acquire databases, significantly enhance existing databases, acquire lists
and acquire data through Company-generated surveys. Such databases and data
enhancements are stated at cost and are amortized over their estimated useful
life of three years.
 
  Internal software represents costs incurred to purchase externally developed
software, external consulting costs and direct internal costs incurred in the
development of various production and administrative applications. Intangible
assets as of December 31, 1996 included $9.7 million related to a major
redesign of the file structure
 
                                      F-8
<PAGE>
 
                     METROMAIL CORPORATION AND AFFILIATES
 
     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS--(CONTINUED)
of the Company's database. This new database structure supports the delivery
of the Company's information service offerings. The costs related to this
redesign will be amortized over its expected period of benefit of five years.
All other internal software is amortized over three years.
 
  Software development costs represent costs incurred to develop database
software which is licensed to clients. The Company capitalizes software
development costs when the technological feasibility of the product has been
assured, through the time at which the product is available for licensing to
its clients, in accordance with Statement of Financial Accounting Standards
No. 86. These costs are amortized over their estimated useful life of three
years. All development costs incurred prior to achieving technological
feasibility are expensed as incurred.
 
 Impairment of Long-lived Assets
 
  The Company periodically assesses whether events or circumstances have
occurred that may indicate the carrying value of its long-lived assets may not
be recoverable. When such events or circumstances indicate the carrying value
of an asset may be impaired, the Company uses an estimate of the future
undiscounted cash flows to be derived from the asset over the remaining useful
life of the asset to assess whether or not the asset is recoverable. If the
future undiscounted cash flows to be derived over the life of the asset do not
exceed the asset's net book value, the Company recognizes an impairment loss
for the amount by which the net book value of the asset exceeds its estimated
fair market value. The Company has not recognized any material impairment
losses for the years ended December 31, 1994, 1995 and 1996. Management does
not believe any material impairment of long-lived assets exists as of December
31, 1996.
 
 Income Taxes
 
  Metromail and its wholly owned subsidiaries have been included in the
consolidated federal income tax return of R. R. Donnelley through June 19,
1996 (the date of completion of the IPO). DBD and ICD have historically been
included in the consolidated tax return of R. R. Donnelley's wholly owned
United Kingdom subsidiaries. The consolidated and combined tax provision is
presented as if the Company filed separate tax returns. Deferred taxes are
provided when tax laws and financial accounting standards differ with respect
to the amount of income calculated in a given year and the bases of assets and
liabilities, in accordance with Statement of Financial Accounting Standards
No. 109. Prior to completion of the IPO, income taxes were paid by R. R.
Donnelley on behalf of Metromail.
 
 Use of Estimates and Assumptions
 
  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, liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
3. TRANSACTIONS WITH R. R. DONNELLEY & SONS COMPANY
 
  Related party transactions with R. R. Donnelley not disclosed elsewhere in
the financial statements are as follows:
 
 Employee Benefit Programs
 
Prior to completion of the IPO, the Company participated in various employee
benefit programs which were sponsored by R. R. Donnelley. These programs
included medical, dental and life insurance and workers'
 
                                      F-9
<PAGE>
 
                     METROMAIL CORPORATION AND AFFILIATES
 
     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS--(CONTINUED)
compensation. The Company reimbursed R. R. Donnelley for its proportionate
cost of these programs based on historical experience and relative headcount.
The costs reimbursed to R. R. Donnelley included costs for reported claims as
well as incurred but not reported claims. The Company recorded expense related
to the reimbursement of these costs of approximately $7.3 million, $8.8
million and $5.5 million in the years ended December 31, 1994 and 1995 and the
period from January 1, 1996 through the completion of the IPO, respectively.
These costs are charged to database and production costs, selling expense and
general and administrative expense based on the number of employees in each of
these categories. The Company believes its allocation of the proportionate
cost is reasonable and, in all material respects, approximates what would have
been incurred had the Company operated on a stand-alone basis prior to
completion of the IPO. Except as discussed below, R. R. Donnelley is liable
for all payments under these programs and, thus, no liability for these
benefits has been reflected on the accompanying balance sheet in respect of
periods ended prior to completion of the IPO.
 
  At the completion of the IPO, the Company and R. R. Donnelley entered into a
Benefit Administration Services Agreement. This agreement, among other things,
permitted the Company to continue to participate in the welfare plans of R. R.
Donnelley until the Company established its own welfare plans, which it did on
July 1, 1996. The Benefit Administration Services Agreement also required the
Company to reimburse R. R. Donnelley for (1) the actual cost of benefits
provided under R. R. Donnelley's employee benefit plans for Company employees
during the period in which the Company continued to participate in such plans
following completion of the IPO and (2) the Company's pro rata share of
administration and plan asset management expenses incurred in the operation of
these plans during such period. The costs incurred by the Company under this
agreement in respect of the Company's participation in R. R. Donnelley's
employee benefit plans for the period from completion of the IPO through
December 31, 1996 were $1.3 million.
 
 Post-Retirement Medical and Life Insurance Benefits
 
  Prior to completion of the IPO, the Company also participated in a post-
retirement benefit program sponsored by R. R. Donnelley, which provides
certain post-retirement medical and life insurance benefits. Prior to
completion of the IPO, the Company reimbursed R. R. Donnelley for its
proportionate cost of these programs based on an actuarial estimation of the
proportionate costs attributable to all of the Company's employees. The
Company recorded expense related to the reimbursement of these costs of
approximately $2.1 million, $1.8 million and $1.2 million in the years ended
December 31, 1994, 1995 and 1996, respectively. Under the Benefit
Administration Services Agreement, the Company assumed the liability to
provide retiree medical and life insurance benefits with respect to active
employees who had not yet satisfied the age and service eligibility
requirements to receive such benefits as of the completion of the IPO and R.
R. Donnelley retained the liability to provide retiree benefits to all active
and terminated employees who had met the age and service requirements for
eligibility as of the completion of the IPO. The liability related to the
portion of post-retirement benefits which will be paid by the Company has been
reflected in other noncurrent liabilities in the accompanying financial
statements in the amounts of $4.8 million and $6.0 million as of December 31,
1995 and 1996, respectively. The liability related to the portion of post-
retirement liability retained by R. R. Donnelley, net of associated deferred
taxes receivable from R. R. Donnelley, has been reflected in other noncurrent
liabilities in the accompanying financial statements.
 
 Corporate Services
 
  Prior to completion of the IPO, R. R. Donnelley provided certain support
services to the Company, including legal, tax, treasury, benefits
administration, real estate, audit and corporate development services. These
charges were allocated by R. R. Donnelley to the Company based on various
formulas which reasonably approximate the actual costs incurred. The expenses
recorded by the Company for these allocations were approximately $1.4 million,
$1.8 million and $1.3 million for the years ended December 31, 1994 and 1995
and
 
                                     F-10
<PAGE>
 
                     METROMAIL CORPORATION AND AFFILIATES
 
     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS--(CONTINUED)
the period from January 1, 1996 through the completion of the IPO,
respectively, and are included in general and administrative expenses in the
accompanying income statements. The amounts allocated by R. R. Donnelley are
not necessarily indicative of the actual costs which may have been incurred
had the Company operated as an entity unaffiliated with R. R. Donnelley during
the periods prior to completion of the IPO. However, the Company believes that
such allocation was reasonable and in accordance with the Securities and
Exchange Commission's Staff Accounting Bulletin No. 55.
 
  At the completion of the IPO, the Company and R. R. Donnelley entered into a
Transition Services Agreement, pursuant to which R. R. Donnelley or its
affiliates agreed to perform certain legal, environmental, real estate, risk
management and tax services for the Company, and the Company agreed to furnish
R. R. Donnelley certain financial information. The costs incurred by the
Company under this agreement for the period from completion of the IPO through
December 31, 1996 were $0.2 million.
 
 Metromail Computer Processing Services
 
  Prior to completion of the IPO, the Company provided computer processing
services to R. R. Donnelley for most of the corporate software applications
used by R. R. Donnelley. The Company charged R. R. Donnelley the estimated
cost of providing these services. These costs include hardware, software and
labor costs associated with running the various application programs used by
R. R. Donnelley. The costs reimbursed by R. R. Donnelley were approximately
$3.1 million, $3.5 million and $1.8 million for the years ended December 31,
1994 and 1995 and the period from January 1, 1996 through the completion of
the IPO, respectively. These amounts have been recorded as reductions of
database and production costs in the accompanying income statement. The
Company believes these reimbursed costs reasonably approximate the actual
costs incurred by the Company.
 
  At the completion of the IPO, the Company entered into a Data Center
Services Agreement with R. R. Donnelley. Under the Data Center Services
Agreement, the Company provides to R. R. Donnelley general computer and data
processing services, including mainframe processing and technical software
systems support and data processing for R. R. Donnelley's internal business
purposes. The Data Center Services Agreement will be in effect for the period
commencing on the closing of the IPO and ending on December 31, 1998. After
December 31, 1998, the Data Center Services Agreement will automatically renew
unless terminated by either party upon six months notice. R. R. Donnelley pays
the Company an annualized fee of $4.3 million for the Company's services under
the agreement during the period ending on December 31, 1996 and, thereafter,
the yearly fee will be adjusted according to changes in R. R. Donnelley's
service needs and increased by an amount equal to the average published
consumer price index increase for the preceding 12 months, measured at
September 30 of each year, provided that such increases shall not exceed six
percent per year. The fees paid by R. R. Donnelley under the agreement for the
period from completion of the IPO through December 31, 1996 were $2.3 million.
 
 Sales through R. R. Donnelley
 
  The Company sold products and services to clients who were also clients of
R. R. Donnelley. For some of these sales, the Company's clients were billed by
R. R. Donnelley. R. R. Donnelley then allocated to the Company that portion of
the revenue attributable to the Company's performed services, as agreed upon
by the Company and its client. Sales approximated $20.9 million, $22.7 million
and $21.8 million for the years ended December 31, 1994, 1995 and 1996,
respectively. The receivables from the Company's clients related to sales
prior to the completion of the IPO are excluded from the Company's balance
sheets as R. R. Donnelley retained risk of loss with collection. The
receivables from R. R. Donnelley related to these sales were included in
short-term debt and advances due to related party discussed in Note 11.

<PAGE>
 
                     METROMAIL CORPORATION AND AFFILIATES
 
     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
  At the completion of the Offering, the Company and R. R. Donnelley entered
into a Sales Agreement. Pursuant to the Sales Agreement, if R. R. Donnelley
successfully sells the services of the Company to a customer, R. R. Donnelley
will, following performance of the services, invoice and seek to collect the
amounts owed from such customer for the services provided by the Company. Upon
collection of such amounts from the customer, R. R. Donnelley will pay over
the collected amount less two percent. Under this agreement, revenue
attributable to the Company's performed services are recognized at the
completion of the Company's services. The Company retains the risk of loss
related to these sales and $4.9 million of sales are included in receivables
at December 31, 1996.
 
 Stock Purchase Plan
 
  Prior to completion of the IPO, the Company participated in a stock purchase
plan for selected managers and key staff employees which was sponsored by R.
R. Donnelley. Under the plan, the Company contributed an amount equal to 70%
of participants' contributions, of which 50% was applied to the purchase of R.
R. Donnelley Common Stock and 20% was paid in cash. Amounts charged to expense
by the Company for this plan were $0.6 million and $0.3 million for the years
ended December 31, 1994 and 1995, respectively. The Company did not
participate in this plan in 1996. Accordingly, no amounts were charged to
expense by the Company for this plan for the year ended December 31, 1996.
Pursuant to the Benefit Administration Services Agreement between R. R.
Donnelley and the Company, the Company ceased being a participant in the R. R.
Donnelley stock purchase plan at completion of the IPO.
 
 Tax Allocation and Indemnification Agreement
 
  Prior to completion of the IPO, the Company was included in the consolidated
federal income tax return of R. R. Donnelley and filed on a combined basis
with R. R. Donnelley in certain states. Thus, rather than paying income taxes
directly in these jurisdictions, the Company made tax sharing payments to R.
R. Donnelley pursuant to R. R. Donnelley's tax allocation policy. In general,
R. R. Donnelley's tax allocation policy provided that the consolidated or
combined tax liability was allocated among the entities in the consolidated or
combined group based principally upon taxable income, credits, preferences and
other amounts directly related to each entity. As a result of completion of
the IPO, the Company is no longer permitted to be included in such
consolidated and combined tax returns. Instead, it files its own federal,
state and local income tax returns and pay its own taxes on a separate company
basis. Pursuant to a Tax Allocation and Indemnification Agreement entered into
by the Company and R. R. Donnelley at the completion of the IPO, the Company
remained obligated to pay to R. R. Donnelley any income taxes shown on R. R.
Donnelley's consolidated and combined tax returns, generally to the extent
attributable to the Company, for calendar year 1995 and for the tax period
(the "Interim Period") beginning on January 1, 1996 and ending on the date of
the consummation of the IPO (to the extent that it has not previously paid
such amounts to R. R. Donnelley). In addition, if the income tax liability
shown on any such consolidated or combined tax return for the Interim Period
and attributable to the Company is adjusted as a result of an action of a
taxing authority or a court, then the Company will pay to R. R. Donnelley the
full amount of any increase in such tax liability (together with any
applicable interest and penalties). Under federal regulations, the Company
will be subject to several liability for the consolidated federal income taxes
for any tax year (including the Interim Period) in which it was a member of
the R. R. Donnelley federal consolidated group (whether or not such taxes are
attributable to the Company). R. R. Donnelley has agreed to indemnify the
Company against such liability and any similar liability under state and local
law. R. R. Donnelley has also agreed to indemnify the Company against any
increase in the Company's income taxes (whether or not related to taxes paid
on a consolidated or combined basis) for periods prior to January 1, 1996 that
results from an action of a taxing authority or a court (except to the extent
such increase provides tax benefits to the Company for periods beginning on or
after January 1, 1996, in which case the sum of such tax benefits will be
retained by R. R. Donnelley or paid by the Company to R. R. Donnelley).

 Impact of Operating as a Stand Alone Entity
 
  The accompanying financial statements reflect all of the Company's costs of
doing business, including all expenses incurred by R. R. Donnelley on the
Company's behalf in accordance with SEC Staff Accounting Bulletin No. 55.
However, the Company estimates that prior to completion of the IPO it would
have incurred increased expenses for additional senior management and
administrative support functions associated with being a stand alone public
entity. In addition, the Company estimates that it would have incurred
additional sales commission expense of approximately $0.5 million for the year
ended December 31, 1995 payable to R. R. Donnelley related to sales to clients
of the Company who are also clients of R. R. Donnelley. These expenses would
have been offset partially by reduced database and production costs as a
result of increased charges for computer services to be provided by the
Company to R. R. Donnelley. The estimated pro forma impact of all of the above
adjustments would have reduced pretax income by approximately $1.6 million for
the year ended December 31, 1995.

</TABLE>
 
  Amortization expense included in the Consolidated and Combined Statements of
Operations was $9.6 million, $14.4 million and $19.8 million for the years
ended December 31, 1994, 1995 and 1996, respectively.
 
7. OTHER ASSETS
 
  Other assets include investment tax credits recorded in connection with an
investment and employment agreement between the Company and the state of
Nebraska. The credits recorded in other assets are approximately $4.0 million
and $4.9 million as of December 31, 1995 and 1996, respectively. Under the
terms of the agreement, the Company must maintain certain investments in plant
and equipment and the number of personnel in the state over a defined period
of time.
 
  The Company records the income derived from this agreement in the period in
which the required wage and capital expenditures are made. The investment
credits will be realized through reductions of sales, use and other state
taxes in future periods. Approximately $3.1 million of these tax credits
expire in the year 2003 and $1.8 million expire in the year 2010. The benefits
associated with these credits are recorded in earnings from operations in the
amount of approximately $1.0 million for each of the years ended December 31,
1994, 1995 and 1996. The credits are classified in database and production
costs, selling expense and general and administrative expense based on a
proration of the amount of wage and capital expenditures applicable to each of
the respective areas.
 
8. PENSION PLAN AND POST-RETIREMENT BENEFITS
 
  The Company's pension plan (the "Plan") is a defined benefit pension plan
sponsored by the Company for its employees. All contributions to the Plan are
made by the Company. Employees are considered eligible when they reach 21
years of age. The Plan provides a normal retirement benefit equal to the sum
of the following:
 
  .  The benefit accrued as of December 31, 1990;
 
  .  1.5% of covered earnings for each year of benefit services earned after
     December 31, 1990, up to a maximum of 38 total years of benefit service
     (including years of benefit service earned prior to 1991);
 
  .  0.5% of covered earnings in excess of covered compensation for each year
     of benefit services earned after December 31, 1990, up to a maximum of
     38 total years of benefit service (including years of benefit service
     earned prior to 1991); and
 
  .  2.0% of covered earnings for each year of benefit service in excess of
     38 years.
 
  Participants are 100 percent vested upon the completion of five years of
vesting service; provided, however, that a participant who was employed by the
Company prior to 1995 will be vested upon attainment of age 55

regardless of such participant's years of service. Plan participants are
eligible for normal benefits at age 65 but may elect early retirement after
age 55. The participants may also elect to continue working beyond age 65 and
defer retirement.
 
  Net pension expenses (credits) included in operating results for the Plan
for the years ended December 31 were:

  The actuarial computations that derived the above amounts assumed a discount
rate on the projected benefit obligations of 7.50% at December 31, 1996, 7.25%
at December 31, 1995 and 8.5% at December 31, 1994, an expected long-term rate
of return on Plan assets of 9.5% and annual salary increases of 4.0%.
 
  In June of 1992 certain accrued benefits and assets relating thereto were
transferred to the Plan from the Oregon Printing Industry Pension Plan (the
"OPI Benefits"). In connection with the IPO, in July of 1996, the OPI Benefits
(approximately $1.9 million) were transferred from the Plan to the R. R.
Donnelley Norwest Pension Plan. Had these assets been excluded from plan
assets, pension expense would not have been materially impacted for the years
ended December 31, 1994, 1995 and 1996, respectively.
 
  Plan assets are mainly invested in marketable securities valued at the last
quoted market price during the fiscal year. The funded status and prepaid
pension cost as of December 31 are as follows:

  In the event of Plan termination, the Plan provides that no funds can revert
to the Company and any excess assets over Plan liabilities must be used to

  Benefits under the Pension Plan are limited to the extent required by
provisions of the Internal Revenue Code and the Employee Retirement Income
Security Act of 1974. If payment of retirement benefits is limited by such
provisions, an amount equal to any reduction in retirement benefits will be
paid as supplemental benefit under the Unfunded Supplemental Benefit Plan
effective January 1, 1996. In 1996, $0.3 million was charged to expense. The
accumulated benefit obligation of $0.4 million was recorded in other accrued
liabilities at December 31, 1996. At December 31, 1996 the related projected
benefit obligation was $1.2 million.
 
  As a subsidiary of R. R. Donnelley, the Company also provided certain health
care and life insurance benefits for retired employees as part of a post-
retirement benefit program sponsored by R. R. Donnelley. Subsequent to the
IPO, the Company continues to provide certain health care and life insurance
benefits for retired employees similar to those sponsored under the R. R.
Donnelley program. Substantially all of the Company's domestic full-time
employees become eligible for those benefits upon reaching age 55 while
working for the Company and having 10 years of continuous service with the
Company or R. R. Donnelley at retirement. The Company does not fund the
liability and thus no plan assets have been considered in the determination of
post-retirement benefit expense below.
 
  The accrual basis expense for all employees of the Company recorded in the
accompanying statements of operations for post-retirement benefit programs
sponsored by R. R. Donnelley or the Company during 1994, 1995 and 1996 is as

  This liability, net of associated deferred taxes receivable from R. R.
Donnelley, has been reflected in other noncurrent liabilities. R. R. Donnelley
is liable for payments of post-retirement medical and life insurance benefits
for all other employees of the Company as of the completion of the IPO.
 
  The actuarial computations assume a discount rate of 7.25% (8.5% at December
31, 1995) and a health care cost trend rate of 8.0%, declining gradually to
5.5% in the year 2023 and thereafter to determine the accumulated post-
retirement benefit obligation. A one percentage point increase in the health
care cost trend rate would increase the 1996 post-retirement benefit expense
by less than $0.1 million and the accumulated post-retirement benefit
obligation as of December 31, 1996 by approximately $0.2 million.

  Caslon Incorporated is a wholly owned subsidiary of R. R. Donnelley. The
Grid Note was paid in full with a portion of the net proceeds of the IPO.
Prior to completion of the IPO, the Grid Note funded operating and investing
activities of the Company's domestic operations. Interest on the Grid Note was
payable on the first day of each calendar quarter based on an interest rate
equal to the prime rate in the preceding calendar quarter as published in The
Wall Street Journal. As of December 31, 1995, the interest rate on the Grid
Note was 8.75%. The Fixed Note was paid in full with a portion of the net
proceeds of the IPO. Interest on the Fixed Note was payable on the first day
of each calendar quarter based on an interest rate equal to 9.75% per annum.
 
  Total accrued interest payable included in the above amounts is $5.2 million
as of December 31, 1995.
 
  The debt is classified on the accompanying balance sheet in accordance with
the above stated terms. The Grid Note and the Fixed Note are classified as
short term at December 31, 1995.
 
  Advances due to related party represents advances from R. R. Donnelley to
fund operating and investing activities, net of cash advanced to R. R.
Donnelley from operating cash flows generated by the Company and receivables
resulting from sales through R. R. Donnelley discussed in Note 3. Prior to
completion of the IPO, this payable was periodically transferred by R. R.
Donnelley into the Grid Note borrowings discussed above.
 
12. DEBT
 
  Prior to the IPO, ICD had a $4.6 million revolving credit agreement. The
amount outstanding under this facility was $1.9 million at December 31, 1995.
 
  The Company has entered into a credit agreement with a syndicate of banks
(the "Credit Agreement") under which it is entitled to borrow up to $45
million on a revolving credit basis. Borrowings under the Credit Agreement
mature in 2001 and bear interest (i) at the prime rate announced by the bank
acting as agent for the syndicate, (ii) at the LIBOR rate plus, depending on
the Company's leverage ratio and fixed charge coverage ratio, up to 42.5 basis
points per annum, or (iii) at a rate determined by competitive bidding. At
December 31, 1996, there was $21.5 million outstanding under the credit
agreement resulting from the repayment of related party debt for ICD and
borrowings to provide operating funds for the Company's U.K. operations.
Interest paid, net of capitalized interest and related party interest, was
$0.6 million in 1996.

     NOTES TO CONSOLIDATED AND COMBINED FINANCIAL STATEMENTS--(CONTINUED)
  The Company has not provided a valuation allowance for deferred tax assets
because, although realization is not assured, the Company believes it is more
likely than not that such tax assets will be recognized through reversals of
taxable timing differences and taxable income in future periods.
 
  Taxes payable are included in debt and advances due to R. R. Donnelley and
its subsidiaries for the year ended December 31, 1995. Taxes payable at
December 31, 1996 are included in other accrued liabilities. Cash payments for
income taxes were $7.2 million for the period from completion of the IPO
through December 31, 1996.
 
14. ACQUISITIONS
 
  The Company acquired Customer Insight Company, Inc. ("CIC") in June 1994 and
a wholly owned subsidiary of R. R. Donnelley acquired ICD in May 1995. Both
acquisitions were accounted for as purchases.
 
  CIC was purchased for approximately $20.0 million. The excess of the
purchase price over the fair market value of net assets acquired, including
identifiable intangible assets, has been allocated to goodwill in the amount
of approximately $16.8 million. The goodwill is being amortized over its
estimated useful life of 15 years.
 
  ICD was purchased for approximately $15.3 million. The excess of the
purchase price over the fair market value of net assets acquired, including
identifiable intangible assets, has been allocated to goodwill in the amount
of $14.7 million. The goodwill is being amortized over its estimated useful
life of 40 years.
 
  In February 1996, a wholly owned subsidiary of R. R. Donnelley contributed
ICD to Metromail. Subsequent to the contribution, ICD purchased all of the net
assets of DBD. This contribution and purchase between entities under R. R.
Donnelley's common control resulted in the historical costs bases of ICD and
DBD (prior to their contribution and purchase) being carried over to Metromail
with no gain or loss recognized as a result of these transactions.
 
15. STOCK INCENTIVE PLANS
 
  The Company has reserved for issuance under the 1996 Stock Incentive Plan
and the 1996 Broad-Based Employee Stock Plan an aggregate of 1,600,000 shares
of Common Stock. Under the 1996 Stock Incentive Plan, 1,168,500 options and
37,000 shares of restricted Common Stock were granted in 1996. The 1,147,500
options granted on June 19, 1996 have an exercise price per share of $20.50
and the 3,500 options granted on August 27, 1996 have an exercise price per
share of $18.1875. These options vest in four annual 25% installments on each
of the first four anniversaries of the date of grant. Non-employee directors
of the Company were granted 17,500 options on September 1, 1996. Such options
have an exercise price per share of $17.5626 and vest on September 1, 1997.
Each option granted under the 1996 Stock Incentive Plan has a 10-year term.
Options to purchase 142,750 shares of Common Stock were granted on June 19,
1996 under the 1996 Broad-Based Employee Stock Plan and have an exercise price
of $20.50. Each such option has a 10-year term and will become exercisable on
June 19, 1999. No options were exercised or cancelled during 1996.
 
  The Company accounts for these plans under APB Opinion No. 25, under which
no compensation cost has been recognized. Had compensation cost for stock
options been determined consistent with FASB Statement No. 123, the Company's
net income and net income per share for 1996 would have been reduced by $1.6
million and $0.07, respectively. These plans were not effective for 1995,
accordingly 1995 and prior years were not affected by this accounting. The
fair value of each option grant is estimated on the date of grant using the
Black-Scholes option pricing model with the following assumptions: weighted
average risk-free interest of 7.1%; no expected dividend yield; expected life
of ten years; weighted average volatility of 36%. Management has provided this
information in accordance with the requirements of FASB Statement No. 123. The
value attached

to the stock options using the Black-Scholes model, which was intended to
value short-term, publicly-traded options, may vary significantly due to the
lack of history to measure the market for the Common Stock. The Company will
continue to revise this calculation annually to report a more current
estimate.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors of
 Atlantes Corporation:
 
  We have audited the accompanying balance sheets of Atlantes Corporation (a
Colorado corporation) as of December 31, 1995 and 1996, and the related
statements of operations, stockholders' equity and cash flows for each of the
three years ended December 31, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these 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 financial statements referred to above present fairly,
in all material respects, the financial position of Atlantes Corporation as of
December 31, 1995 and 1996, and the results of its operations and its cash
flows for each of the three years ended December 31, 1996 in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                (INFORMATION AS OF MARCH 31, 1997 IS UNAUDITED)
 
(1) ORGANIZATION AND BUSINESS
 
 Nature of Business
 
  Atlantes Corporation (the "Company") was incorporated in the state of
Colorado in September 1991. The Company has developed a proprietary computer
database which accumulates and provides access to consumer product purchasing
information. The Company provides consumer database management services,
primarily to durable goods manufacturers, in exchange for consumer product
purchasing information and the right to sell selected parts of the consumer
database, in the form of customer lists, to the direct marketing industry. The
Company also provides consumer database and information design services to its
customers.
 
  As of March 31, 1997, the Company has an accumulated deficit of $1,917,742,
and has incurred operating losses for each of the previous three full fiscal
years. The Company may need additional working capital in the future; however,
there is no assurance that such working capital will be available. Management
plans to fund future operations through various sources including (a) current
cash on hand, (b) increased continuing revenue, and (c) funding from a line-
of-credit from a financial institution (Note 7).
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Database Development
 
  The costs of developing and analyzing the consumer database are expensed as
incurred.
 
 Property and Equipment
 
  Property and equipment are carried at original cost. Depreciation is
calculated on the straight-line method over the estimated useful lives
(ranging from 3 to 7 years) of the respective assets. The cost of normal
maintenance and repairs is expensed as incurred. Material expenditures which
increase the life of an asset are capitalized and depreciated over the
estimated remaining useful life of the asset. The cost of properties sold, or
otherwise disposed of, and the related accumulated depreciation is removed
from the respective accounts, and any resulting gains or losses are reflected
in current operations.
 
 Revenue Recognition Policy
 
  Revenue is recorded when the services have been performed, the data has been
delivered to the customer, and all significant contingencies regarding the
transaction are satisfied.
 
 Interim Results (unaudited)
 
  The accompanying balance sheet as of March 31, 1997, the statements of
operations and of cash flows for the three months ended March 31, 1996 and
1997, and the statement of stockholders' equity for the three months ended
March 31, 1997 are unaudited. In the opinion of management, these interim
financial statements have been prepared on the same basis as the audited
financial statements and include all adjustments, consisting only of normal
recurring adjustments, necessary for the fair statement of the results of the
interim periods. Operating results for the three months ended March 31, 1997
are not necessarily indicative of the results that may be expected for the
year ending December 31, 1997.

                             ATLANTES CORPORATION
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 Fair Value of Financial Instruments
 
  The Company's financial instruments consist of cash and short-term trade
receivables and payables. The carrying values of cash and short-term trade
receivables and payables approximate fair value.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions. These estimates and assumptions may affect the reported amounts
of assets and liabilities, disclosure of contingent assets and liabilities at
the date of the financial statements, and the reported amounts of revenue and
expenses during the reporting period. Actual results could differ from those
estimates.
 
 Concentration of Credit and Market Risk
 
  The Company has no significant off balance-sheet concentrations of credit
risk such as foreign exchange contracts, options contracts or other foreign
hedging arrangements. The Company maintains the majority of its cash with
financial institutions, in the form of demand deposits.
 
  The Company performs ongoing evaluations of its customers' financial
condition and generally does not require collateral. Its accounts receivable
balances are domestic and are concentrated among institutions within the
direct marketing industry which is a concentration of market risk. The
Company's operations may be affected by economic fluctuations in this
industry.
 
 Net Income (Loss) Per Share
 
  The Company's net income (loss) per share is based upon the weighted average
of common stock outstanding. Common stock issuable upon the exercise of stock
options and stock warrants has been included in the computation, to the extent
dilutive, using the treasury stock method.
 
 Income Taxes
 
  Income taxes are accounted for in accordance with Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS No. 109").
SFAS No. 109 requires recognition of deferred income tax assets and
liabilities for the expected future income tax consequences, based on enacted
tax laws, of temporary differences between the financial reporting and tax
bases of assets, liabilities and carryforwards. Deferred tax assets are
recognized for the expected future effects of all deductible temporary
differences, loss carryforwards and tax credit carryforwards. Deferred tax
assets are then reduced, if deemed necessary, by a valuation allowance for the
amount of any tax benefits which, more likely than not based on current
circumstances, are not expected to be realized (see Note 6).
 
 Effects of Recently Issued Accounting Pronouncements
 
  In March 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 128, "Earnings Per Share"
("SFAS No. 128"), which supersedes Accounting Principles Board Opinion No. 15,
"Earnings Per Share" ("APB No. 15"). SFAS No. 128 simplifies the requirements
for reporting earnings per share ("EPS") by requiring companies only to report
"basic" and "diluted "EPS. SFAS No. 128 is effective for both interim and
annual periods ending after December 15, 1997 but requires retroactive
restatement upon adoption. The Company will adopt SFAS No. 128 in the fourth
quarter of 1997. The Company does not believe such adoption will have a
material effect on either its previously reported earnings per share.
 
  In March 1997, the FASB issued Statement of Financial Accounting Standards
No. 129, "Disclosure of Information about Capital Structure" ("SFAS No. 129"),
which continues the existing requirements of APB No. 15 but expands the number
of companies subject to portions of its requirements. Specifically, SFAS No.
129 requires that entities previously exempt from the requirements of APB No.
15 disclose the pertinent rights and privileges of all securities in addition
to ordinary common stock. SFAS No. 129 is effective for periods ending after
December 15, 1997. The Company was not exempt from APB No. 15; accordingly,
the adoption of SFAS No. 129 will not have any effect on the Company.

(3) STOCKHOLDERS' EQUITY
 
 Common Stock and Warrants
 
  During December 1993, the Company issued units of Company securities for $40
per unit. Each unit entitles the holder to five shares of common stock and one
warrant to purchase common stock for $1 per share. The $40 unit price was
allocated $6.83 to each share of common stock and $5.83 to each warrant. As of
December 31, 1993, the Company had issued 13,381 units by converting principal
and accrued interest on notes payable of $90,240 in exchange for 2,256 units
and 11,125 units in exchange for a $445,000 subscription receivable. The
subscription receivable was paid in January 1994. Also in connection with the
transaction, three shareholders received warrants to purchase 7,900 shares of
the Company's common stock for $1 in consideration for loans previously made
to the Company. These warrants were issued at no cost to the holders.
 
  During June 1994, the Company entered into a securities purchase agreement
to issue 5,000 units of common stock for $40 per unit. Each unit entitles the
holder to five shares of common stock and one warrant to purchase common stock
at $1 per share. The $40 unit price was allocated $6.83 to each share of
common stock and $5.83 to each warrant. The Company received cash proceeds of
$100,000 and converted $100,000 of principal and accrued interest on notes
payable to stockholders to equity.
 
  During November 1994, the Company issued warrants to purchase 26,075 shares
of the Company's common stock for $1 per share in connection with notes
payable agreements.
 
  During January 1995, the Company issued 12,109 shares of common stock for
$82,705 of cash and converted $477,130 of principal and accrued interest on
notes payable to stockholders into 69,858 shares of common stock.
 
  As of December 31, 1996, the Company has reserved 100,287 shares of common
stock for issuance upon exercise of outstanding warrants. Each warrant
entitles the holder to purchase one share of common stock at $1 per share. The
purchase right represented by the warrant is exercisable in whole or in part,
at any time following the grant date until the earlier of five years from the
grant date or the effective date of an initial public offering.
 
 Stock Option Plan
 
  The Company has adopted a Stock Option Plan (the "Plan") to provide
directors, officers and other employees options to purchase up to 122,910
shares of the Company's common stock. Under the terms of the Plan, the Board
of Directors may grant directors, officers and employees either nonqualified
or incentive stock options (as defined by the Internal Revenue Service). The
options vest annually over a five-year period with the first year vested in
advance unless special provisions are voted on by the Board of Directors on an
individual basis, and expire ten years from the date of grant. In addition,
vesting will be automatic upon the sale of the Company or a merger whereby the
Company is not the surviving entity. Total compensation related to the grant
of stock options at less than their fair market value on the date of grant
through December 31, 1995 and 1996 totaled $425,845 and $530,345,
respectively, of which $160,782, $84,003 and $104,903 were recorded for the
years ended December 31, 1994, 1995 and 1996, respectively, and has been
included in general and administrative expense, and as of December 31, 1996,
$180,657 of deferred compensation will be recognized over the remaining
vesting period.
 
 Statement of Financial Accounting Standards No. 123 ("SFAS 123")
 
  SFAS 123, "Accounting for Stock-Based Compensation," defines a fair value
based method of accounting for employee stock options or similar equity
instruments. However, SFAS 123 allows the continued measurement of
compensation cost for such plans using the intrinsic value based method
prescribed by APB Opinion No. 25,

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
"Accounting for Stock Issued to Employees" ("APB 25"), provided that pro forma
disclosures are made of net income or loss, assuming the fair value based
method of SFAS 123 had been applied. The Company has elected to account for
its stock-based compensation plans under APB 25; accordingly, for purposes of
the pro forma disclosures presented below, the Company has computed the fair
values of all options granted during 1996 using the Black-Scholes pricing
model and the following weighted average assumptions (no options were granted
during 1995):
 
<TABLE>
<CAPTION>
                                                                         1996
                                                                       ---------
      <S>                                                              <C>
      Risk-free interest rate.........................................     6.44%
      Expected dividend yield.........................................        0%
      Expected lives outstanding...................................... 5.0 years
      Expected volatility.............................................     .001%
</TABLE>
 
  To estimate the lives of options for this valuation, it was assumed options
will be exercised upon becoming fully vested. All options are assumed to vest.
Cumulative compensation costs recognized in pro forma net income or loss with
respect to options that are forfeited prior to vesting is adjusted as a
reduction of pro forma compensation expense in the period of forfeiture.
Because the Company's common stock is not publicly traded, the expected market
volatility assumed to be .001%. Actual volatility of the Company's common
stock may vary. Fair value computations are highly sensitive to the volatility
factor assumed; the greater the volatility, the higher the computed fair value
of options granted.
 
  For the years ended December 31, 1995 and 1996, the Company recorded $84,003
(relating to options granted prior to 1995) and $104,903, respectively, of
compensation expense, in accordance with APB 25. Additional pro forma stock-
based compensation, net of the effect of forfeitures, was $0 and $7,932 for
1995 and 1996, respectively. These amounts are amortized ratably over the
vesting periods of the options or recognized at date of grant if no vesting
period is required.
 
  If the Company had accounted for its stock-based compensation plans in
accordance with SFAS 123, the Company's net loss and pro forma net loss would
have been reported as follows:
 
<TABLE>
<CAPTION>
                                                             1995       1996
                                                           ---------  ---------

                Pro forma................................  $(519,324) $(302,044)
</TABLE>
 
  Because the SFAS 123 method of accounting has not been applied to options
granted prior to January 1, 1995, the resulting pro forma compensation cost
may not be representative of that to be expected in future years.
 
  A summary of stock options as of December 31, 1994, 1995 and 1996 and
changes during the years then ended is presented below:

  Rent expense was $41,708, $32,242 and $41,535 for the years ended December
31, 1994, 1995 and 1996, respectively.
 
  The Company is subject to various claims and business disputes in the
ordinary course of business. Management does not anticipate that the ultimate
outcome of these issues will have a material impact on the Company's financial
position or results of operations.
 
(5) MAJOR CUSTOMERS
 
  For 1994, 1995 and 1996, the Company had one major customer which
individually comprised more than 10% of total sales. Revenue from this
customer totaled approximately 75%, 78% and 86%, respectively, of total
revenue. At December 31, 1995 and 1996, this customer comprised approximately
50% and 62% of accounts receivable, respectively.
 
(6) INCOME TAXES
 
  From its inception, the Company has generated losses in each full fiscal
year for both financial reporting and tax purposes. The potential future tax
benefit of the net operating loss carryforward is approximately $572,000 as of
December 31, 1996. This asset has been completely offset by a valuation
allowance because it does not satisfy the realization criteria set forth in
SFAS No. 109.
 
  For income tax reporting purposes, the Company may utilize approximately
$1,500,000 of net operating loss carryforwards which expire beginning in 2009.
The Tax Reform Act of 1986 contains provisions which may limit the net
operating loss carryforwards available to be used in any given year if certain
events occur, including changes in ownership interests, such as that discussed
in Note 7.

(7) SUBSEQUENT EVENTS (UNAUDITED)
 
  On March 12, 1997, the Company entered into a $250,000 revolving line of
credit with a financial institution. The revolving line of credit bears
interest at prime plus 1.5%, is due on March 12, 1998, and is collateralized
by certain assets of the Company. The revolving line of credit also includes
various covenants and restrictions, some of which relate to quick ratio and
tangible net worth and profitability. The Company was in compliance with its
covenants as of March 31, 1997.
 
  On May 17, 1997, the Company entered into an agreement with Metromail
Corporation ("Metromail"), pursuant to which the Company would become a
wholly-owned subsidiary of Metromail upon consummation of the merger, which is
expected in the second or third quarter of 1997.

and Dissenting Shares) as to which an Election is not in effect at the
Election Date shall be called "Non-Electing Common Shares." If Parent and the
Company shall determine for any reason that any Election was not properly made
with respect to shares of Company Common Stock, such Election shall be deemed
to be ineffective and shares of Company Common Stock covered by such Election
shall, for purposes hereof, be deemed to be Non-Electing Common Shares.
 
  2.5. Proration of Company Warrants. The manner in which each Company Warrant
shall be converted in the Merger into shares of Parent Common Stock or the
right to receive cash shall be as set forth in this Section 2.5.
 
  (a) The portion of Company Warrants, with respect to the number of shares of
Company Common Stock issuable upon exercise of such Company Warrants, to be
converted in the Merger into the right to receive cash shall not exceed the
lesser of
 
    (i) the product of 15% times the total number of shares of Company Common
  Stock issuable upon exercise of the Company Warrants outstanding
  immediately prior to the Effective Time; and
 
    (ii) such number as shall be determined by Parent at the Effective Time
  such that the amount of cash paid in respect of Company Warrants pursuant
  to Section 2.2(e)(i) shall not exceed the product of (A) 15% times (B) the
  sum of (1) such amount of cash plus (2) the product of (I) the Effective
  Date Parent Common Stock Value times (II) the number of shares of Parent
  Common Stock delivered pursuant to Section 2.2(f)(i)
 
(rounded down to the nearest whole share, the "Maximum Warrant Cash
Election").
 
  (b) If Cash Elections are received for a number of shares (the "Cash
Electing Warrant Shares") of Company Common Stock issuable upon exercise of
Company Warrants which exceeds the Maximum Warrant Cash Election, the number
of Cash Electing Warrant Shares to be converted into cash (and the contingent
right to receive Parent Common Stock) pursuant to Section 2.2(e) shall equal
the Maximum Warrant Cash Election. The Exchange Agent shall determine by lot
(or by such other method as is deemed reasonable by Parent and the Company)
which of such Cash Electing Warrant Shares shall be so converted. The balance
of such Cash Electing Warrant Shares shall be so converted into shares of
Parent Common Stock (and the contingent right to receive Parent Common Stock)
pursuant to Section 2.2(f).
 
  (c) If Cash Elections are received for a number of shares of Company Common
Stock issuable upon exercise of Company Warrants which is less than or equal
to the Maximum Warrant Cash Election, each Cash Electing Warrant Share shall
be converted in the Merger into the right to receive cash (and the contingent
right to receive Parent Common Stock) pursuant to Section 2.2(e).
 
  (d) Each Non-Electing Warrant Share (as defined in Section 2.5(e)) and each
share of Company Common Stock issuable upon exercise of Company Warrants for
which Stock Elections have been received shall be converted into shares of
Parent Common Stock (and the contingent right to receive Parent Common Stock)
pursuant to Section 2.2(f).
 
  (e) For the purpose of this Section 2.5, shares of Company Common Stock
issuable upon exercise of Company Warrants as to which an Election is not in
effect at the Election Date shall be called "Non-Electing Warrant Shares." If
Parent and the Company shall determine for any reason that any Election was
not properly made with respect to any Company Warrant, such Election shall be
deemed to be ineffective and shares of Company Common Stock issuable upon
exercise of Company Warrants covered by such Election shall, for purposes
hereof, be deemed to be Non-Electing Warrant Shares.
 
  2.6. Company Stock Options. The manner in which Company Stock Options shall
be converted in the Merger into shares of Parent Common Stock or the right to
receive cash shall be as set forth in this Section 2.6.
 
  (a) For each share of Company Common Stock issuable upon exercise of Company
Stock Options with respect to which a Cash Election is received (the "Cash
Electing Option Shares"), each such share shall be
 
                                      A-9
<PAGE>
 
converted in the Merger into the right to receive cash (and the contingent
right to receive Parent Common Stock) pursuant to Section 2.2(g).
 
  (b) Each Non-Electing Option Share (as defined in Section 2.6(c)) and each
share of Company Common Stock issuable upon exercise of Company Stock Options
for which Stock Elections have been received shall be converted into shares of
Parent Common Stock (and the contingent right to receive Parent Common Stock)
pursuant to Section 2.2(h).
 
  (c) For the purpose of this Section 2.6, shares of Company Common Stock
issuable upon exercise of Company Stock Options as to which an Election is not
in effect at the Election Date shall be called "Non-Electing Option Shares."
If Parent and the Company shall determine for any reason that any Election was
not properly made with respect to any Company Stock Option, such Election
shall be deemed to be ineffective and shares of Company Common Stock issuable
upon exercise of Company Stock Options covered by such Election shall, for
purposes hereof, be deemed to be Non-Electing Option Shares.
 
  2.7. Parent to Make Cash Available. Parent shall make available to Mergerco,
which in turn shall make available to the Exchange Agent on the Effective
Date, cash sufficient to satisfy the payments to be made pursuant to Sections
2.2(c)(i), 2.2(e)(i) and 2.2(g)(i) (such cash to be included as part of the
Exchange Fund as defined in Section 2.8). After the Effective Time, the
Exchange Agent shall distribute to holders of shares of Company Common Stock,
Company Warrants and Company Stock Options converted into the right to receive
cash (and the contingent right to receive Parent Common Stock) pursuant to
Sections 2.2(c), 2.2(e) and 2.2(g), respectively, upon surrender to the
Exchange Agent (to the extent not previously surrendered with a Form of
Election) of one or more Company Certificates, Warrant Certificates or Stock
Option Agreements for cancellation, a check for an amount equal to the amounts
determined pursuant to Sections 2.2(c)(i), 2.2(e)(i) and 2.2(g)(i), such
distribution to be made as soon as practicable (but no later than 30 days)
following such surrender. In no event shall the holder of any such surrendered
Company Certificates, Warrant Certificates or Stock Option Agreements be
entitled to receive interest on any of the funds to be received in the Merger.
If such check is to be sent to a Person other than the Person in whose name
the Company Certificates, Warrant Certificates or Stock Option Agreements are
registered, it shall be a condition of the exchange that the Person requesting
such exchange shall pay to the Exchange Agent any transfer or other taxes
required by reason of the delivery of such check to a Person other than the
registered holder of the Company Certificates surrendered or other than the
Person listed on any Warrant Certificate or Stock Option Agreement, or shall
establish to the satisfaction of the Exchange Agent that such tax has been
paid or is not applicable. Notwithstanding the foregoing, neither the Exchange
Agent nor any party hereto shall be liable to a holder of a Company
Certificate, Warrant Certificate or Stock Option Agreement for any amount paid
to a public official pursuant to any applicable abandoned property, escheat or
similar law.
 
  2.8. Parent to Make Stock Certificates Available. (a) As soon as practicable
after the Effective Time (but no later than 30 days), Parent shall deposit
with the Exchange Agent, in trust for the holders of Company Certificates,
Warrant Certificates and Stock Option Agreements, Parent Certificates
representing the shares of Parent Common Stock issuable pursuant to Sections
2.2(d), 2.2(f) and 2.2(h) in exchange for the outstanding shares of Company
Common Stock, Company Warrants and Company Stock Options, and cash as required
to make payments in lieu of any fractional shares pursuant to Section 2.10
(such cash and shares of Parent Common Stock, together with any dividends or
distributions with respect thereto in accordance with Section 2.9 and cash
deposited pursuant to Section 2.7, being hereinafter referred to as the
"Exchange Fund").
 
  (b) As soon as practicable after the Effective Time (but no later than 30
days), the Exchange Agent shall mail or otherwise deliver to each record
holder of a Company Certificate, Warrant Certificate or Stock Option Agreement
a letter of transmittal (which shall specify that delivery shall be effected,
and risk of loss and title to the Company Certificates, Warrant Certificates
or Stock Option Agreements shall pass, only upon actual delivery thereof to
the Exchange Agent and shall contain instructions for use in effecting the
surrender of the Company Certificates, Warrant Certificates or Stock Option
Agreements in exchange for the property described in the next
 
                                     A-10

sentence). Upon surrender for cancellation to the Exchange Agent of all
Company Certificates, Warrant Certificates or Stock Option Agreements (to the
extent not previously surrendered with a Form of Election) held by any record
holder of a Company Certificate, Warrant Certificate or Stock Option Agreement
together with such letter of transmittal duly executed, such holder shall be
entitled to receive in exchange therefor a Parent Certificate representing the
number of whole shares of Parent Common Stock into which the shares of Company
Common Stock represented by the surrendered Company Certificates, Warrant
Certificates or Stock Option Agreements shall have been converted at the
Effective Time pursuant to this Article II, cash in lieu of any fractional
share of Parent Common Stock in accordance with Section 2.10 and certain
dividends and other distributions in accordance with Section 2.9; and the
Company Certificates, Warrant Certificates or Stock Option Agreements so
surrendered shall forthwith be cancelled.
 
  (c) Any portion of the Exchange Fund which remains undistributed to the
former holders of shares of Company Common Stock, Company Warrants and Company
Stock Options for six months after the Effective Time shall be delivered to
Parent, upon its request, and any such former holders who have not theretofore
complied with this Article II shall thereafter look only to Parent for payment
of their claim for shares of Parent Common Stock, any cash in lieu of
fractional shares of Parent Common Stock, any dividends or distributions with
respect to such shares of Parent Common Stock and any cash deposited pursuant
to Section 2.7. Neither Parent nor the Company shall be liable to any former
holder of shares of Company Common Stock, Company Warrant or Company Stock
Option for any such shares of Parent Common Stock held in the Exchange Fund
which are delivered to a public official pursuant to any applicable abandoned
property, escheat or similar law.
 
  (d) At the Effective Time, the stock transfer books of the Company shall be
closed, and no transfer of shares of Company Common Stock shall thereafter be
made. If, after the Effective Time, Company Certificates are presented to the
Surviving Corporation, they shall be cancelled and exchanged as provided in
this Article II.
 
  2.9. Dividends and Distributions; Withholding. (a) Any dividend or other
distribution paid in respect of Parent Common Stock to holders of record on or
after the Effective Date and otherwise payable to the holder of an outstanding
Company Certificate, Warrant Certificate or Stock Option Agreement shall,
until the surrender of such Company Certificate, Warrant Certificate or Stock
Option Agreement and the issuance of a Parent Certificate in respect thereof,
be retained by Parent, and no such dividend or other distribution payable in
respect of Parent Common Stock shall be paid to such holder until such Company
Certificate, Warrant Certificate or Stock Option Agreement shall have been so
surrendered to Parent. Upon surrender of each such Company Certificate,
Warrant Certificate or Stock Option Agreement and issuance in exchange
therefor of shares of Parent Common Stock, there shall be paid by Parent to or
at the direction of the holder of the Parent Certificate, the amount of all
dividends and distributions which became payable to holders of record on or
after the Effective Date in respect of the number of whole shares of Parent
Common Stock represented by the Parent Certificate so issued. In no event
shall the holder of any Company Certificate, Warrant Certificate or Stock
Option Agreement be entitled to receive interest on any of the funds to be
received in the Merger or on any such dividend or other distribution.
 
  (b) Parent or the Exchange Agent shall be entitled to deduct and withhold
from the consideration (cash, shares of Parent Common Stock or any combination
thereof, as applicable) otherwise payable pursuant to this Agreement to any
holder of shares of Company Common Stock, Company Warrants or Company Stock
Options such amounts as Parent or the Exchange Agent is required to deduct and
withhold with respect to the making of such payment under the Code, or any
provision of state, local or foreign Tax law (it being understood that the
Company shall be responsible for any employer's tax liability relating to any
such consideration or payment). On or before the business day preceding the
Effective Date, the Company will supply a certificate to Parent and the
Exchange Agent to determine the extent of such deductions or withholding and
the Company represents and warrants that such certificate will be complete and
correct. To the extent that amounts are so withheld by Parent or the Exchange
Agent, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the shares of Company Common
Stock, Company Warrants or Company Stock Options in respect of which such
deduction and withholding was made by Parent or the Exchange Agent.

  2.10. Fractional Shares.. No certificates for fractions of shares of Parent
Common Stock and no scrip or other certificates evidencing fractional
interests in such shares shall be issued pursuant to Section 2.2. If the
conversion of a Person's aggregate holdings of Company Common Stock, Company
Warrants and Company Stock Options at any time results in a fractional share
of Parent Common Stock or interest therein, such Person shall, in lieu
thereof, be paid cash (without interest), rounded to the nearest cent, in an
amount determined by multiplying (i) the Effective Date Parent Common Stock
Value by (ii) the fractional interest to which such holder would otherwise be
entitled. Any person otherwise entitled to a fractional share or interest
shall not be entitled by reason thereof to any voting, dividend or other
rights as a stockholder of Parent.
 
  2.11. Changes in Parent Common Stock. In the event that, during the period
between the date hereof and the Effective Time, any reclassification, stock
split, stock dividend or similar change in respect of the Parent Common Stock
shall occur, then appropriate adjustment shall be made in the number of shares
of Parent Common Stock and/or kind of securities issued as Parent Common Stock
in order to provide holders of Company Common Stock, Company Warrants and
Company Stock Options with the same number of shares of Parent Common Stock
and/or other securities that they would have received after such
reclassification, stock split, stock dividend or similar change if the
Effective Time had occurred immediately prior to such reclassification, stock
split, stock dividend or similar change (and all references herein to the
Parent Common Stock shall be deemed to refer to such adjusted number and/or
kind of securities).
 
  2.12. Dissenters' Rights. Notwithstanding any provision of this Agreement to
the contrary, any Dissenting Shares shall not be converted into or represent a
right to receive any of the consideration provided in Section 2.2, but the
holder shall only be entitled to such rights as are granted by the CBCA. If a
holder of shares of Company Common Stock who has asserted dissenters' rights
as to such shares under Article 113, Section 202 of the CBCA shall effectively
withdraw or otherwise lose (through failure to perfect or otherwise) the right
to dissenters' rights, then, as of the Effective Time or the occurrence of
such event, whichever last occurs, such shares of Company Common Stock shall
be converted into and represent only the right to receive the consideration
provided in Section 2.2(d), without interest, upon the surrender of the
Company Certificate or Company Certificates representing such shares of
Company Common Stock. The Company shall give Parent prompt notice of any
written demands for dissenters' rights of any shares of Company Common Stock,
attempted withdrawals of such demands, and any other instruments served
pursuant to the CBCA received by the Company relating to dissenters' rights.
The Company shall not, except with the prior written consent of Parent,
voluntarily make any payment with respect to any demands for dissenters'
rights, offer to settle any demands or approve any withdrawal of any such
demands.

Firm of the unresolved objections submitted to it pursuant Section 3.3(d) was
closer to the position taken by Parent than to the position taken by the
Contingent Payment Committee. Any fees and expenses payable by the Record
Holders pursuant to this Section 3.3(f) shall be, to the extent available,
paid and offset against any amounts otherwise payable to Record Holders.
 
  3.4. Delivery and Valuation of Contingent Shares. (a) On each Contingent
Share Delivery Date or as promptly as practicable thereafter, Parent shall
deposit with the Exchange Agent in trust for the Record Holders certificates
representing the total number of Contingent Shares, if any, to be paid on such
Contingent Share Delivery Date pursuant to this Article III.
 
  (b) On each Contingent Share Delivery Date, each Record Holder shall be
entitled to receive, with respect to each share of Company Common Stock deemed
to be held by such Record Holder according to the Record Holder List, the
number of validly issued, fully paid and nonassessable shares of Parent Common
Stock determined by dividing (i) the Contingent Payment Amount Per Share for
the applicable Measurement Period by (ii) the Parent Stock Price for such
Measurement Period.
 
  (c) In the event of any reclassification, stock split or stock dividend with
respect to the Parent Common Stock, any change of the Parent Common Stock into
other securities or any other dividend or distribution with respect to the
Parent Common Stock, other than quarterly cash dividends, as the same may be
adjusted from time to time in the ordinary course, or if a record date with
respect to any of the foregoing should occur after a Contingent Share Earned
Date and prior to a Contingent Share Delivery Date, the number of shares
determined in accordance herewith shall be appropriately adjusted so as to
afford the equitable benefit of such changes to the Record Holders.
 
  (d) Unless and until certificates for Contingent Shares shall be delivered
to the Record Holders, no dividends payable to holders of record of shares of
Parent Common Stock shall be paid to the Record Holders with respect to such
Contingent Shares, but there shall be paid to the Record Holders (i) upon such
delivery to the Record Holders or as soon as practicable thereafter,
dividends, without interest, with a record date on or after the relevant
Contingent Share Delivery Date and a payment date prior to the date of
delivery of such certificate to the Record Holder; and (ii) at the appropriate
payment date or as soon as practicable thereafter, the dividends, without
interest, with a record date prior to the delivery of the certificate to the
Record Holders, but on or after the applicable Contingent Share Delivery Date,
and a payment date subsequent to such delivery.
 
  (e) The Exchange Agent shall deliver any certificates representing
Contingent Shares payable to the Record Holders pursuant to this Article III
to the Record Holders at the addresses of the Record Holders as they appeared
on the stock records of the Company at the Effective Time or such other
addresses as the Record Holders shall provide to the Exchange Agent by written
notice. No fractional shares of Parent Common Stock
 
                                     A-16
<PAGE>
 
shall be issued or delivered pursuant to this Article III. In lieu of any
fractional shares, any Record Holder otherwise entitled hereunder to receive
fractional shares of Parent Common Stock but for this Section 3.4(e) will be
entitled hereunder to receive instead a cash payment in lieu thereof, without
interest, in an amount equal to (i) the fraction of a share to which such
Record Holder would otherwise have been entitled multiplied by (ii) the Parent
Stock Price with respect to the applicable Contingent Share Delivery Date.
 
  3.5. Contingent Payment Committee. By accepting any consideration under this
Agreement each Record Holder shall be deemed to have agreed as follows:
 
    (a) The Record Holders irrevocably appoint and authorize the Contingent
  Payment Committee to act as their agent hereunder with such powers as are
  delegated hereunder to the Contingent Payment Committee, together with such
  other powers as are incidental thereto, and to take such other actions in
  connection with the foregoing as the Contingent Payment Committee may deem
  necessary or appropriate, including without limitation, agreeing to any
  adjustments to the definitions contained in this Article III or to the
  tables contained in Schedule 3.2. The Contingent Payment Committee (i)
  shall have no duties or responsibilities except as expressly set forth
  herein, (ii) shall not be responsible in its capacity as the Contingent
  Payment Committee for any recitals, statements, representations or
  warranties contained herein, or in any certificate or other document
  referred to herein, the validity, effectiveness or enforceability of this
  Agreement, the failure of the Company to achieve any targets, or the
  failure of any party to perform any of its obligations hereunder, (iii)
  shall not be required to initiate or conduct any litigation or collection
  proceedings, and (iv) shall not be responsible for any action taken or
  omitted to be taken hereunder, except for, in the case of any member of the
  Contingent Payment Committee, his own gross negligence or willful
  misconduct. The Contingent Payment Committee may consult with legal
  counsel, independent public accountants and other experts selected by it at
  the sole expense of the Record Holders, and shall not be liable for any
  action taken or omitted to be taken in good faith by them in accordance
  with the advice of such counsel, independent public accountants or experts.
 
    (b) The Contingent Payment Committee shall be entitled to rely upon any
  certification, notice or other communication 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 delivered in accordance with this Agreement. The
  Contingent Payment Committee shall not be required to take any action which
  shall expose the members thereof to personal liability or which is contrary
  to this Agreement or applicable law.
 
    (c) The Contingent Payment Committee shall not be deemed to have
  knowledge or notice of the occurrence of any event unless they shall have
  received written notice thereof in accordance with this Agreement.
 
    (d) The Record Holders agree to indemnify the Contingent Payment
  Committee ratably in accordance with their proportionate interests in the
  Contingent Payment Amounts for any and all Losses and Expenses of any kind
  and nature whatsoever that may be imposed on, incurred by or asserted
  against the Contingent Payment Committee in its capacity as such in any way
  relating to or arising out of this Agreement or the transactions
  contemplated hereby, including the enforcement of any of the terms hereof,
  and the Contingent Payment Committee shall be entitled to direct Parent to
  make any future Contingent Payment Amounts to the Contingent Payment
  Committee to the extent of such Losses and Expenses.
 
    (e) Parent and the Company shall be entitled to rely on any and all
  action taken by the Contingent Payment Committee under this Agreement
  without any liability to, or obligation to inquire of, any of the Record
  Holders, and shall be entitled to rely on any written action purporting on
  its face to be an action of the Contingent Payment Committee and signed by
  any two members of the Contingent Payment Committee as an action of the
  Contingent Payment Committee.
 
  3.6. Assignability. The right of each Record Holder to receive shares of
Parent Common Stock pursuant to this Agreement may not be assigned or
transferred in any manner whatsoever except by operation of law or by will. In
no event shall any right to Contingent Shares pursuant to this Article III be
evidenced by negotiable certificates of any kind.

  3.7. Maximum Number of Contingent Shares; Maximum Aggregate Contingent
Payment Amounts. (a) The aggregate number of Contingent Shares to which Common
Record Holders shall be entitled pursuant to the terms of this Article III
shall not exceed the number of Fixed Shares received by such Common Record
Holders pursuant to Section 2.2(d)(i), and the aggregate number of Contingent
Shares to which Common Record Holders and Warrant Record Holders shall be
entitled pursuant to the terms of this Article III shall not exceed the number
of Fixed Shares. The number of Fixed Shares received by Common Record Holders
and the total number of Fixed Shares shall be specified separately in a
certificate mutually agreed by the parties hereto and delivered at the
Closing. Such certificate, as so delivered, shall be deemed to form a part of
this Agreement. The maximum number of Contingent Shares is subject to
adjustment pursuant to Section 3.4(c).
 
  (b) The aggregate Contingent Payment Amount to which Record Holders shall be
entitled pursuant to the terms of this Article III shall not exceed the excess
of (i) the amount specified in Schedule 3.2 as the maximum aggregate
Contingent Payment Amount minus (ii) the aggregate Contingent Payment Target
Shortfalls for all Measurement Periods (it being understood that nothing in
this Section 3.7(b) requires Record Holders to return to the Company or Parent
any shares of Parent Common Stock delivered to Record Holders with respect to
any Measurement Period on account of Contingent Payment Target Shortfalls that
occur in any Measurement Period subsequent to such Measurement Period).
 
  3.8. Right of Offset.
 
  (a) Subject to the provisions of this Section 3.8, Parent shall have the
right to offset against, and reduce the amounts otherwise payable in respect
of, the Contingent Payment Amount for any Measurement Period (including,
without limitation, any Measurement Period ending after the occurrence of an
Exceptional Event):
 
    (i) the aggregate of any Losses and Expenses incurred by any Parent Group
  Member in connection with or arising from any breach or failure to perform
  by the Company of any of its agreements, covenants or obligations in this
  Agreement required to be performed on or prior to the Effective Date;
 
    (ii) the aggregate of any Losses and Expenses incurred by any Parent
  Group Member in connection with or arising from any breach of any warranty
  as of the Effective Date or the inaccuracy as of the Effective Date of any
  representation or warranty contained or referred to in this Agreement or
  any certificate delivered by or on behalf of the Company pursuant hereto;
 
    (iii) the amount determined pursuant to Section 8.1(h);
 
    (iv) the aggregate legal and accounting expenses (including fees,
  expenses and disbursements) incurred by the Company in connection with the
  preparation, negotiation, execution and delivery of this Agreement and the
  consummation of the Merger to the extent such legal and accounting expenses
  exceed $125,000;
 
    (v) the fees and expenses of the Accounting Firm as and to the extent
  provided in Section 3.3(f); and
 
    (vi) the fees payable to Wallach in excess of the amounts specified in
  Schedule 5.25.
 
  (b) No amounts shall be offset against or reductions made pursuant to
Section 3.8(a)(i) or (ii) until the aggregate amount of Losses and Expenses
incurred by the Parent Group Members under Section 3.8(a)(i) or (ii) exceeds
$250,000, in which case the aggregate amount of all Losses and Expenses
incurred by the Parent Group Members under Section 3.8(a)(i) or (ii) in excess
of $250,000 may be offset pursuant to Section 3.8(a)(i) or (ii).
 
  (c) The right of offset provided for in this Section 3.8 shall continue
until the obligations of Parent to make any contingent payments under Article
III shall have been satisfied; provided, that the rights of offset under
Section 3.8(a)(ii) shall terminate on the eighteen month anniversary of the
Effective Time with respect to all representations and warranties in this
Agreement or in any certificate delivered pursuant hereto (other than with
respect to the representations and warranties contained in Section 5.1(b),
(c), (d) or (e) or 5.7, which shall continue as provided above), except that
such rights shall continue as to any Loss or Expense of which any Parent Group
Member has notified the Contingent Payment Committee in accordance with the
requirements of this Section 3.8 on or prior to the date such offset rights
would otherwise terminate in accordance with this
 
                                     A-18
<PAGE>
 
Section 3.8, as to which such offset rights shall continue until the rights to
offset and the amount of the offset shall have been determined pursuant to
this Section 3.8.
 
  (d) Any claim on account of Losses and Expenses which is not a Third Party
Claim (as defined below) shall be asserted by written notice (an "Offset Claim
Notice") given by Parent to the Contingent Payment Committee. An Offset Claim
Notice in respect to any action at law or suit in equity by a third party as
to which offset will be sought ("Third Party Claim") shall be given promptly
after the action, suit, investigation, or proceeding is commenced; provided,
that failure to give such notice shall not prejudice Parent hereunder, unless
such failure shall have materially prejudiced the Record Holders. Any Offset
Claim Notice shall describe in reasonable detail the facts giving rise to a
claim for offset hereunder, the amount or method of computation of the amount
of such claim, and a reference to the provision of this Agreement giving rise
to such claim. The Contingent Payment Committee shall have a period of 30 days
within which to respond thereto. If the Contingent Payment Committee does not
respond within such 30 day period, the Contingent Payment Committee shall be
deemed to have accepted the claim for offset and shall have no further right
to contest the validity of such claim. If the Contingent Payment Committee
does respond within such 30-day period and rejects such claim in whole or in
part, the dispute shall be resolved: (i) by the written agreement between
Parent and the Contingent Payment Committee; (ii) by binding arbitration
pursuant to Section 11.16; or (iii) by any other means to which Parent and the
Contingent Payment Committee shall agree. All disputes shall be resolved no
later than four years and eleven months after the Closing Date.
 
  (e) If any Offset Claim Notice received by the Contingent Payment Committee
remains unresolved on a Contingent Share Delivery Date, the portion of the
Contingent Payment Amount, if any, which is not subject to any claim of offset
shall be paid in accordance with this Article III. Following the final
determination of the amount of offset pursuant to the procedures specified in
(d) above, any remaining Contingent Payment Amount (without interest) which
shall have been determined to be not subject to offset shall be paid promptly
in accordance with this Article III, except that for purposes of any delivery
of Contingent Shares in respect of such unresolved claims after such
Contingent Share Delivery Date, "Parent Stock Price" shall be determined by
reference to the 10 consecutive trading days ending five trading days
immediately preceding such subsequent date of delivery; "Contingent Payment
Amount" shall mean the remaining portion of the Contingent Payment Amount due
to Record Holders; and "Contingent Share Delivery Date" shall mean the date
designated by Parent no later than 15 days following the final determination
of the remaining Contingent Payment Amount due.
 
  (f) Parent shall have the obligation to conduct and control, through counsel
of its choosing, the defense, compromise or settlement of any Third Party
Claim as to which offset will be sought by Parent hereunder; provided, that
the Contingent Payment Committee may participate, through counsel chosen by it
and at its own expense, in the defense of any such claim, action or suit; and
provided, further, that Parent shall not, without the written consent of the
Contingent Payment Committee (which written consent shall not be unreasonably
withheld), pay, compromise or settle any such claim, action or suit, except
that no such consent shall be required if, following a written request from
Parent, the Contingent Payment Committee shall fail, within 14 days after the
making of such request, to acknowledge and agree in writing that, if such
claim, action or suit shall be adversely determined, Parent can offset Losses
and Expenses relative to such claim, action or suit as provided in this
Section 3.8; and provided, further, that if Parent does not conduct the
defense of any such Third Party Claim, the Contingent Payment Committee shall
have the right to do so, at the expense of Parent, but, in such case, the
Contingent Payment Committee shall not, without the written consent of Parent
(which consent shall not be unreasonably withheld), compromise or settle such
claim, action or suit. Notwithstanding the foregoing, Parent shall have the
right to pay, settle or compromise any such claim, action or suit without such
consent, provided that in such event Parent shall waive any right to offset
therefor hereunder unless such consent is unreasonably withheld.
 
  (g) Except for remedies which cannot be waived as a matter of law,
including, without limitation remedies for fraud, if the Closing occurs, the
exclusive remedy of Parent on account of the matters described in Section
3.8(a)(i) through (vi) shall be the rights set forth in this Section 3.8.

  3.9. Time Limit. Notwithstanding any other provision of this Agreement, no
later than five years after the Effective Time, Parent will transfer to the
Exchange Agent in trust for the Record Holders, and the Exchange Agent will
transfer to the Record Holders, certificates representing the total number of
Contingent Shares to be paid, if any, pursuant to this Article III; and in no
event will any Contingent Shares be issued to a Record Holder more than five
years after the Effective Date.
 
  3.10. Operation of the Business of the Company After the Effective Time.
During the period subsequent to the Effective Date and prior to December 31,
2001, Parent shall operate or cause the business of the Company to be operated
in conformity with sound business practices and shall make and cause to be
made all business decisions with respect to the business of the Company in
good faith. It is the current intention of Parent to provide the Company with
a reasonable opportunity to meet the Record Flow Performance Targets for each
of the Measurement Periods.
 
  3.11. Contingent Payments Following Exceptional Events. (a) If an
Exceptional Event shall occur after the Effective Date and on or prior to
December 31, 1997, or during the first Measurement Period, then the Payment
Percentage for each Measurement Period shall be deemed to be 100%.
 
  (b) If an Exceptional Event shall occur during any Measurement Period (other
than the first Measurement Period), then the Payment Percentage for each
Measurement Period not completed prior to the occurrence of such Exceptional
Event shall be the percentage set forth in Table 3.2(b) determined to be
applicable based on a Performance Percentage equal to the lesser of (i) 100%
or (ii) the average of the Performance Percentages for all Measurement Periods
completed prior to the occurrence of such Exceptional Event.
 
  (c) If an Exceptional Event shall occur, then, notwithstanding Section 3.3,
the Contingent Share Delivery Date with respect to each Measurement Period
ending after the date of the occurrence of such Exceptional Event shall be
such date no later than 15 days after the end of such Measurement Period as
shall be designated by Parent, provided that if the Exceptional Event is an
event described in clause (iii), clause (iv) (unless the cessation of business
described in such clause has occurred following a change in regulatory
requirements that in the reasonable judgment of Parent has made it inadvisable
for the Company to continue such business) or clause (v) of the definition of
Exceptional Event, the Contingent Payment Committee may, by notice to Parent
within 15 days following the occurrence of such Exceptional Event, elect, on
behalf of all Record Holders, to have there be a single Contingent Share
Delivery Date, which date shall be no later than 15 days following Parent's
receipt of such notice, and for the Record Holders to receive in the
aggregate, in lieu of all amounts otherwise payable under this Article III
after the date of such Exceptional Event, the number of shares of Parent
Common Stock determined by dividing (i) an amount equal to the present value
(using a discount rate determined in accordance with Schedule 3.11) of the
Contingent Payment Amounts otherwise payable following such Exceptional Event
in the absence of the election under this proviso by (ii) the Parent Stock
Price.
 
  3.12. Delivery of Only Parent Common Stock. Except as provided in Sections
3.4(d) (relating to dividends with a record date on or after the applicable
Contingent Share Delivery Date) and 3.4(e) (relating to cash in lieu of
fractional shares), but otherwise notwithstanding anything to the contrary in
this Article III, in no event shall any consideration be delivered to Record
Holders pursuant to this Article III other than in the form of Parent Common
Stock.

such qualification, and no other jurisdiction has demanded, requested or, to
the best of the Company's knowledge, otherwise indicated that the Company is
required so to qualify. The Company has full corporate power and authority to
own or lease and to operate and use its assets and to carry on its business as
now conducted. True and complete copies of the Articles of Incorporation and
all amendments thereto and of the By-laws, as amended, of the Company have
been delivered to Parent.

public accountants, attorneys, environmental consultants and financial
advisors), reasonable access during normal business hours to the offices,
properties, employees and business and financial records (including, without
limitation, computer files, retrieval programs and similar documentation) of
the Company or Parent, as the case may be, to the extent Parent or the
Company, as the case may be, shall deem necessary or desirable, and shall
furnish to Parent or the Company, as the case may be, or such party's
authorized representatives such additional information concerning the
operations, properties and businesses of the Company or Parent, as the case

Company or such party's authorized representatives to verify the accuracy of
the representations and warranties contained in this Agreement, to verify the
accuracy of the financial statements referred to in Sections 5.4 or contained
or referred to in the Parent SEC Documents, as the case may be, and to
determine whether the conditions set forth in Articles IX have been satisfied.
Parent and the Company agree that such investigations shall be conducted in
such manner as not to interfere unreasonably with the operation of the
business of the Company or Parent, as the case may be. No investigation made
by Parent or the Company or such party's authorized representatives hereunder
shall affect the representations and warranties of the parties hereunder.
 
  7.5. Preserve Accuracy of Representations and Warranties. Each of the
parties hereto shall refrain from taking any action which would render any
representation or warranty contained in Article V or VI of this Agreement
inaccurate as of the Effective Time. Each party shall promptly notify the
other parties of any action, suit or proceeding that shall be instituted or
threatened against such party to restrain, prohibit or otherwise challenge the
legality of any transaction contemplated by this Agreement. Each party shall
promptly notify the other parties of any lawsuit, claim, proceeding or
investigation that may be instituted or, to the best knowledge of such party,
threatened against such party which would have been listed in Schedule 5.22 or
Schedule 6.8, respectively, if such lawsuit, claim, proceeding or
investigation had arisen prior to the date hereof.

consent, approval or waiver, in form and substance reasonably satisfactory to
Parent, from any party to any Company Agreement required to satisfy the
conditions set forth in Section 9.3(b); provided that no party hereto shall
have any obligation to offer or pay any consideration in order to obtain any
such consents or approvals; and provided, further, that the Company shall not

9.1(c); provided that the Company shall not make any agreement or
understanding affecting the Company or its assets or business as a condition
for obtaining any such consents or approvals except with the prior written

as expressly contemplated by this Agreement, the Company shall carry on its

on the Company, (ii) any notice or other communication from any third Person
alleging that the consent of such third Person is or may be required in
connection with the transactions contemplated by this Agreement, and (iii) any
material default under any Company Agreement or event which, with notice or
lapse of time or both, would become such a default on or prior to the
Effective Time and of which the Company has knowledge.
 
  7.9. Mutual Cooperation; Reasonable Best Efforts. (a) Upon the terms and
subject to the conditions set forth in this Agreement, each of the parties
hereto agrees to use its reasonable best efforts to take, or cause to be

advisable, to consummate and make effective, as soon as reasonably
practicable, the Merger.
 
  (b) Each party hereto shall use its reasonable best efforts not to take any
action, or to enter into any transaction, which would cause any of its
representations or warranties contained in this Agreement to be untrue or to
result in a breach of any of its covenants in this Agreement.
 
  7.10. No Solicitation. The Company shall not, nor shall it authorize or
permit any of its Affiliates or any officer, director, employee, investment
banker, attorney or other adviser or representative of the Company or any of
its Affiliates to, (i) solicit, initiate, or encourage the submission of, any
Acquisition Proposal (as hereinafter defined) or (ii) enter into any agreement
with respect to any Acquisition Proposal, participate in any discussions or
negotiations regarding, or furnish to any person any information for the
purpose of facilitating the making of, or take any other action to facilitate
any inquiries or the making of, any proposal that constitutes, or may
reasonably be expected to lead to, any Acquisition Proposal. Without limiting
the foregoing, it is understood that any violation, of which the Company or
any of its Affiliates had actual knowledge at the time of such violation, of
the restrictions set forth in the immediately preceding sentence by any
officer, director, employee, investment banker, attorney, employee, or other
adviser or representative of the Company or any of its Affiliates, whether or
not such Person is purporting to act on behalf of the Company or any of its
Affiliates or otherwise, shall be deemed to be a breach of this Section 7.10
by the Company and its Affiliates. The Company promptly shall advise Parent of
any Acquisition Proposal and any inquiries with respect to any Acquisition
Proposal. For purposes of this Agreement, "Acquisition Proposal" means any
proposal for a merger or other business combination involving the Company or
any of its Affiliates or any proposal or offer to acquire in any manner,
directly or indirectly, an equity interest in the Company or any of its
Affiliates, any voting securities of the Company or any of its Affiliates or a
substantial portion of the assets of the Company.
 
  7.11. Listing Application. Parent will promptly file an application to list
on the NYSE, subject to official notice of issuance, the Merger Shares to be
issued pursuant to Section 3.1 and will use its reasonable best efforts to
effect such listing on the NYSE, subject to official notice of issuance, on or
prior to the Effective Time.

Company, in form and
 
                                     A-40
<PAGE>
 
substance reasonably satisfactory to Parent and as is reasonably customary in
scope and substance for letters delivered by independent public accountants in
connection with transactions such as those contemplated by this Agreement.
 
  (b) Parent shall use its reasonable best efforts to cause to be delivered to
the Company a "comfort" letter of Arthur Andersen, Parent's independent public
accountants, dated the date on which the Registration Statement shall become
effective, and addressed to the Company and Parent, in form and substance
reasonably satisfactory to the Company and as is reasonably customary in scope
and substance for letters delivered by independent public accountants in
connection with transactions such as those contemplated by this Agreement.
 
  7.14. Reorganization. During the period from the date of this Agreement
through the Effective Time, unless Parent and the Company shall otherwise
agree in writing, neither Parent nor the Company shall knowingly take or fail
to take any action which action or failure would jeopardize qualification of
the Merger as a reorganization within the meaning of Section 368(a) of the
Code or would cause any of the representations and warranties set forth in the
Company Tax Certificate or the Parent Tax Certificate to be untrue or
incorrect in any material respect.
 
  7.15. Affiliate Letters. Prior to the Effective Time, the Company shall
cause to be prepared and delivered to Parent a list (reasonably satisfactory
to counsel for Parent) identifying each person who, at the time of the Company
Shareholder Meeting, may be deemed to be an "affiliate" of the Company, as
such term is defined for purposes of paragraphs (c) and (d) of Rule 145 under
the Securities Act (the "Rule 145 Affiliates"). The Company shall use its
reasonable best efforts to cause each person who is identified as a Rule 145
Affiliate in such list to deliver to Parent on or prior to the Effective Time,
a written agreement, in a form substantially as set forth as Exhibit B hereto,
that such Rule 145 Affiliate represents and covenants that such Person will
not, among other things, sell, transfer or otherwise dispose of any Fixed
Shares issued to such Rule 145 Affiliate in connection with the Merger, except
pursuant to an effective registration statement or in compliance with Rule 145
or another exemption from the registration requirements of the Securities Act,
having provided an opinion of counsel reasonably acceptable to Parent to such
effect. After the Effective Time, Parent shall satisfy the conditions set
forth in Rule 144(c)(1) promulgated by the SEC under the Securities Act for so
long as any Rule 145 Affiliate is subject to the provisions of Rule 145(d).

                             Additional Agreements
 
  8.1. Accounts Receivable. (a) As promptly as practicable following the
Closing Date (but not later than 30 days after the Closing Date), the Company
shall prepare, in accordance with the generally accepted accounting
principles, a schedule (the "Preliminary Receivables Schedule") setting forth
the outstanding gross amount of the uncollected accounts receivable of the
Company as of the Effective Date.
 
  (b) Promptly following receipt of the Preliminary Receivables Schedule, the
Contingent Payment Committee may review the same and, within 30 days after the
date of such receipt, may deliver to Parent a certificate setting forth their
objections to the Preliminary Receivables Schedule, together with a summary of
the reasons therefor and calculations which, in their view, are necessary to
eliminate such objections. If the Contingent Payment Committee does not so
object within such 30-day period the determinations set forth in the
Preliminary Receivables Schedule shall be final and binding on Parent and each
of the Record Holders, and the Preliminary Receivables Schedule shall
constitute the "Receivables Schedule."
 
  (c) If the Contingent Payment Committee so objects within such 30-day
period, Parent and the Contingent Payment Committee shall use their reasonable
efforts to resolve by written agreement (the "Agreed Receivables Adjustments")
any differences as to the determinations set forth in the Preliminary
Receivables Schedule and, in the event the Contingent Payment Committee and
Parent so resolve any such differences, the determinations set forth in the
Preliminary Receivables Schedule as adjusted by the Agreed Receivables
Adjustments shall be final
 
                                     A-41
<PAGE>
 
and binding on Parent and each of the Record Holders, and the Preliminary
Receivables Schedule as so adjusted shall constitute the "Receivables
Schedule."
 
  (d) If any objections raised by the Contingent Payment Committee are not
resolved by Agreed Receivables Adjustments within the 30-day period next
following such 30-day period, then Parent and Contingent Payment Committee
shall submit the objections that are then unresolved to the Accounting Firm
which shall be directed by Parent and the Contingent Payment Committee to
resolve the unresolved objections as promptly as reasonably practicable and to
deliver written notice to each of Parent and the Contingent Payment Committee
setting forth its resolution of the disputed matters, and the determinations
set forth in the Preliminary Receivables Schedule as adjusted by the Agreed
Receivables Adjustments and by its resolution of such objections shall be
final and binding on Parent and each of the Record Holders, and the
Preliminary Receivables Schedule as so adjusted shall constitute the
"Receivables Schedule."
 
  (e) The parties hereto shall make available to Parent, the Contingent
Payment Committee and, if applicable, the Accounting Firm, such books, records
and other information (including work papers) as any of the foregoing may
reasonably request to prepare or review the Preliminary Receivables Schedule
or any matters submitted to the Accounting Firm.
 
  (f) The fees and expenses of the Accounting Firm shall be paid by Parent if
the determination by the Accounting Firm of the unresolved objections
submitted to it pursuant to Section 8.1(d) was closer to the position taken by
the Contingent Payment Committee than to the position taken by Parent and
shall be paid by Parent, which shall have the right to offset such payment
pursuant to Section 3.8, if the determination by the Accounting Firm of the
unresolved objections submitted to it pursuant to Section 8.1(d) was closer to
the position taken by the Contingent Payment Committee.
 
  (g) From and after the Closing Date, Parent shall cause the Company to use
its best efforts to collect the accounts receivable reflected in the
Receivables Schedule (the "Receivables") generally in accordance with the
billing and collection practices presently applied by the Company in the
collection of its accounts and notes receivable, except that with respect to
any particular Receivable, neither Parent nor the Company shall be under any
obligation to commence or not to commence litigation to effect collection and
may make any adjustment, concession or settlement which in the good faith
judgment of Parent is commercially reasonable. In connection with such
collections, if a payment is received from a debtor who has not designated the
invoice being paid thereby, such payment shall be applied to the earliest
invoice outstanding to the Company with respect to indebtedness of such
account debtor, except for those invoices which are subject to a dispute to
the extent of such dispute.
 
  (h) If, after giving effect to all adjustments, concessions and settlements
made and collection fees incurred (in each case in accordance with Section
8.1(g), Company has not collected, within 12 months after the Closing Date, an
amount equal to the excess of the Receivables over $5,000 (such excess being
referred to herein as the "Net Amount of Receivables"), then Parent shall have
the right to set-off against, and to reduce the amounts payable in respect of,
the Contingent Payment Amount for any Measurement Period equal to:
 
    (i) the Net Amount of Receivables, minus
 
    (ii) the amount collected in cash (after giving effect to the items set
  forth above) by the Company during such 12-month period in respect of the
  Receivables.
 
  8.2. Third Party Standstill Agreements. During the period from the date of
this Agreement through the Effective Time, the Company shall not terminate,
amend, modify or waive any provision of any confidentiality or standstill
agreement to which the Company is a party (other than any involving Parent).
During such period, the Company shall enforce, to the fullest extent permitted
under applicable law, the provisions of any such agreement, including, but not
limited to, by obtaining injunctions to prevent any breaches of such
agreements and to enforce specifically the terms and provisions thereof in any
court of the United States of America or of any state having jurisdiction.
 
                                     A-42
<PAGE>
 
  8.3. Indemnification of Directors. (a) For a period of not less than six
years from and after the Effective Time, Parent agrees to, and to cause the
Surviving Corporation to, indemnify and hold harmless all past and present
directors (the "Indemnified Parties") of the Company to the full extent such
persons may be indemnified by the Company pursuant to the Company's Articles
of Incorporation and Bylaws as in effect as of the date hereof for acts and
omissions occurring at or prior to the Effective Time and shall advance
reasonable litigation expenses incurred by such persons in connection with
defending any action arising out of such acts or omissions, provided that such
persons provide the requisite affirmations and undertaking, as set forth in
Article 109, Section 104 of the CBCA.
 
  (b) Any Indemnified Party will promptly notify the Parent and the Surviving
Corporation of any claim, action, suit, proceeding or investigation for which
such party may seek indemnification under this Section; provided, however,
that the failure to furnish any such notice shall not relieve Parent or the
Surviving Corporation from any indemnification obligation under this Section
except to the extent Parent or the Surviving Corporation is materially
prejudiced thereby. In the event of any such claim, action, suit, proceeding,
or investigation, (x) the Surviving Corporation will have the right to assume
the defense thereof, and the Surviving Corporation will not be liable to such
Indemnified Parties for any legal expenses of other counsel or any other
expenses subsequently incurred thereafter by such Indemnified Parties in
connection with the defense thereof, except that all Indemnified Parties (as a
group) will have the right to retain one separate counsel, reasonably
acceptable to such Indemnified Party and Parent, at the expense of the
indemnifying party if the named parties to any such proceeding include both
the Indemnified Party and the Surviving Corporation and the representation of
such parties by the same counsel would be inappropriate due to a conflict of
interest between them, (y) the Indemnified Parties will cooperate in the
defense of any such matter, and (z) the Surviving Corporation will not be
liable for any settlement effected without its prior written consent.

    cash, if any, received in lieu of fractional shares of Parent Common
    Stock), increased by any gain recognized by reason of the receipt of
    such cash in such exchange, and increased by any amount treated as
    interest;
 
      (v) Except to the extent of Parent Common Stock treated as interest,
    the holding period for shares of Parent Common Stock received in
    exchange for Company Common Stock pursuant to the Merger
 
                                     A-44
<PAGE>
 
    will include the holding period of the Company Common Stock exchanged
    therefor, provided such Company Common Stock was held as a capital
    asset by the shareholder at the Effective Time; and
 
      (vi) A shareholder of the Company who receives cash in lieu of a
    fractional share of Parent Common Stock will recognize gain or loss
    equal to the difference, if any, between such shareholder's tax basis
    in such fractional share (as described in clause (iv) above) and the
    amount of cash received.
 
In rendering such opinion, Holland & Hart LLP may receive and rely upon
representations of the Company, Parent and certain shareholders of the
Company.

   each be a party to such reorganization within the meaning of Section

    Stock), increased by any gain recognized by reason of the receipt of
    such cash in such exchange, and increased by any amount treated as
    interest;
 
      (v) Except to the extent of Parent Common Stock treated as interest,
    the holding period for shares of Parent Common Stock received in
    exchange for Company Common Stock pursuant to the Merger will include
    the holding period of the Company Common Stock exchanged therefor,
    provided such Company Common Stock were held as a capital asset by the
    shareholder at the Effective Time; and
 
      (vi) A shareholder of the Company who receives cash in lieu of a
    fractional share of Parent Common Stock will recognize gain or loss

  failure of the Merger to have occurred on or prior to such date; or (ii)
  any court or other Governmental Entity having jurisdiction over a party
  hereto shall have issued an order, decree or ruling or taken any other

  (b) This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their successors and permitted assigns. The successors and
permitted assigns hereunder shall include without limitation, in the case of

claim under or by reason of this Agreement.
 
  11.6. Entire Agreement; Amendments. This Agreement and the Exhibits and
Schedules referred to herein and the documents delivered pursuant hereto

This Agreement shall not be amended, modified or supplemented except by a
written instrument signed by an authorized representative of each of the
parties hereto.
 
  11.7. Interpretation. Titles to articles and headings to sections herein are
inserted for convenience of reference only and are not intended to be a part
of or to affect the meaning or interpretation of this Agreement. The Schedules

  11.8. Waivers. Any term or provision of this Agreement may be waived, or the
time for its performance may be extended, by the party or parties entitled to
the benefit thereof. Any such waiver shall be validly and
 
                                     A-49
<PAGE>
 
sufficiently authorized for the purposes of this Agreement if, as to any
party, it is authorized in writing by an authorized representative of such
party. The failure of any party hereto to enforce at any time any provision of
this Agreement shall not be construed to be a waiver of such provision, nor in
any way to affect the validity of this Agreement or any part hereof or the
right of any party thereafter to enforce each and every such provision. No
waiver of any breach of this Agreement shall be held to constitute a waiver of
any other or subsequent breach.
 
  11.9. Enforcement of this Agreement. The parties hereto agree that
irreparable damage would occur in the event that any of the terms or
provisions of this Agreement were not performed in accordance with their
specific wording or were otherwise breached. It is accordingly agreed that
each of the parties hereto shall be entitled to an injunction or injunctions
to prevent breaches of this Agreement and to enforce specifically the terms
and provisions hereof in any court of the United States of America or any
state having jurisdiction, such remedy being in addition to any other remedy
to which any party may be entitled at law or in equity.
 
  11.10. Fees and Expenses. Except as otherwise provided in Section 3.8 and
except that, if the Merger is consummated, Parent shall pay Wallach the

respect of its services to the Company, each of the parties hereto shall bear
its own costs and expenses (including, without limitation, fees and
disbursements of its counsel, accountants and other financial, legal,
accounting or other advisors and any expenses incurred by or on behalf of any
party in connection with the Registration Statement and the Proxy
Statement/Prospectus), incurred by it in connection with the preparation,
negotiation, execution, delivery and performance of this Agreement.
 
  11.12. Partial Invalidity. Wherever possible, each provision hereof shall be
interpreted in such manner as to be effective and valid under applicable law,
but in case any one or more of the provisions contained herein shall, for any
reason, be held to be invalid, illegal or unenforceable in any respect, such
provision shall be ineffective to the extent, but only to the extent, of such
invalidity, illegality or unenforceability without invalidating the remainder
of such invalid, illegal or unenforceable provision or provisions or any other
provisions hereof, unless such a construction would be unreasonable.
 
  11.12. Execution in Counterparts. This Agreement may be executed in one or
more counterparts, each of which shall be considered an original instrument,
but all of which shall be considered one and the same agreement, and shall
become binding when one or more counterparts have been signed by each of the
parties hereto and delivered to each of the other parties.
 
  11.13. Further Assurances. From time to time after the Effective Time, the

related to this Agreement or any of the transactions contemplated hereby to
the non-exclusive jurisdiction of the United States District Court for the
Northern District of Illinois and the jurisdiction of any court of the State
of Illinois located in Chicago, Illinois, and irrevocably waives any immunity
from the jurisdiction of such courts and any claim of improper venue, forum
non conveniens or any similar objection which it might otherwise be entitled
to raise in any such suit, action or proceeding.
 
  11.16. Arbitration. Any controversy arising under, out of, in connection
with, or relating to, this Agreement, and any amendment hereof, or the breach
hereof, shall be determined and settled by arbitration in Denver, Colorado, by
a person or persons mutually agreed upon, or in the event of a disagreement as
to the selection of

of substantial benefit to other dissenters similarly situated, and that the
fees for those services should not be assessed against the corporation, the
court may award to said counsel reasonable fees to be paid out of the amounts
awarded to the dissenters who were benefitted.

The Board of Directors
Atlantes Corporation
90 Madison Street
Denver, CO 80206
 
Members of the Board:
 
  You have requested our opinion as to the fairness, from a financial point of
view, to the common shareholders of Atlantes Corporation (the "Company") of
the proposed merger (the "Merger") of MML Merging Company, a wholly owned
subsidiary of Metromail Corporation ("Acquiror"), with and into the Company,
pursuant to the Merger Agreement dated May 17, 1997 (the "Agreement"). Under
the terms of the Agreement, each outstanding share of Company common stock, no
par value, will be converted into 1.241 shares of Acquiror common stock, $.01
par value (the "Company/Acquiror Exchange Ratio") or into $25.99 in cash. In
addition, each common shareholder of the Company may be entitled to future
payments ("Contingent Payment Amount") of Acquiror common stock if certain
performance criteria are met by the Company following the Merger. While the
management of the Company believes that these performance criteria can be met,
there can be no assurance that they will be attained or that any future
consideration will be received by the Company's shareholders.
 
  In arriving at our opinion, we have, among other things:
 
    i.reviewed certain financial statements and other financial information
  of the Company;
 
    ii.reviewed the current condition and growth prospects for the Company,
  including financial data prepared by Company management;
 
    iii.discussed the past and current operations and financial conditions
  and the prospectus of the Company, including the need for future equity
  capital, with Company management;
 
    iv.considered the prospect for value, liquidity, and growth if the
  Company were to remain independent;
 
    v.reviewed the process used in marketing the Company, including a review
  of the potential acquirors contacted and their responses relative to a
  potential acquisition of the Company;
 
    vi.compared the various offers received from interested parties and
  determined that the Acquiror offer represented the highest value in
  absolute terms;
 
    vii.examined the price and trading activity for Acquiror;
 
    viii. reviewed the Agreement among Acquiror and the Company;
 
    ix.analyzed the price obtainable for the Company's shares at this time
  compared with the risks involved and possible price available at a later
  time;
 
    x.reviewed the implications for the Company's shareholders receiving
  Acquiror stock with regards to prospects for value, liquidity, dividend
  yield and growth;
 
    xi.met with Acquiror management and reviewed certain publicly available
  financial statements of Acquiror;
 
    xii.evaluated the future growth prospects of Acquiror following the
  Merger.
 
  We have assumed without independent verification the accuracy and
completeness of the financial and other information regarding the Company that
was provided to potential acquirors. We have not prepared or acquired an
independent valuation or appraisal of any of the assets. With respect to
business plans and forecasts, we have assumed that they have been reasonably
prepared on a basis reflecting the best currently available estimates and
judgments of the management of the Company as to the future performance of the
Company. Furthermore, we have assumed that the Merger will be consummated on a
timely basis in accordance with its terms and pursuant to the Agreement. We
have also taken into account our assessment of general economic, market and
financial
<PAGE>
 
conditions as they exist, as well as our experience in connection with similar
transactions and securities valuations generally. Our opinion necessarily is
based upon conditions as they exist and can be evaluated as of the date of
this opinion.
 
  The Wallach Company is an investment banking firm engaged in the valuation
of business and their securities in connection with mergers and acquisitions,
private placements, and valuations for corporate and other purposes. The
Wallach Company, as the Company's financial adviser, assisted with the
marketing and negotiations leading to the Agreement for which it has and will
receive compensation.
 
  It is understood that this letter is for the information of the Company's
Board of Directors only and may not be used for any other purpose without our
prior written consent, provided, however, that we hereby consent to the
inclusion of this opinion in any registration statement or proxy statement
used in connection with the Merger so long as the opinion is included in its
entirety in such registration statement or proxy statement.
 
  Based on our analysis of the foregoing, the assumptions described above and
upon such other factors we deem relevant, it is our opinion that, as of the
date hereof, the consideration to be received by each of the Company's
shareholders in the Merger, including the Company/Acquiror Exchange Ratio and
the potential Contingent Payment Amount, is fair to the Company's shareholders
from a financial point of view.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Reference is made to Section 145 ("Section 145") of General Corporation Law
of the State of Delaware (the "Delaware GCL") which provides for
indemnification of directors and officers in certain circumstances.
 
  In accordance with Section 102(b)(7) of the Delaware GCL, the Registrant's
Restated Certificate of Incorporation provides that directors shall not be
personally liable for monetary damages for breaches of their fiduciary duty as
directors except for (i) breaches of their duty of loyalty to the Registrant
or its stockholders, (ii) acts or omissions not in good faith or which involve
intentional misconduct or knowing violations of law, (iii) certain
transactions under Section 174 of the Delaware GCL (unlawful payment of
dividends) or (iv) transactions from which a director derives an improper
personal benefit.
 
  The Restated Certificate of Incorporation of the Registrant provides for
indemnification of directors and officers to the full extent provided by the
Delaware GCL, as amended from time to time. It states that the indemnification
provided therein shall not be deemed exclusive. The Registrant may maintain
insurance on behalf of any person who is or was a director, officer, employee
or agent of the Registrant, or another corporation, partnership, joint
venture, trust or other enterprise against any expense, liability or loss,
whether or not the Registrant would have the power to indemnify such person
against such expense, liability or loss, under the provisions of the Delaware
GCL.
 
  Pursuant to Section 145 and the Restated Certificate of Incorporation, the
Registrant maintains directors' and officers' liability insurance coverage.

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 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 a 20 percent change
    in the maximum aggregate offering price set forth in the "Calculation
    of Registration Fee" table in the effective registration statement; and
 
      (iii) To include any material information with respect to the plan 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) The undersigned Registrant hereby undertakes that, for purposes of
  determining any liability under the Securities Act of 1933, each filing of
  the Registrant's annual report pursuant to section 13 (a) or 15 (d) of the
  Securities Exchange Act of 1934 (and, where applicable, each filing of an
  employee benefit plan's annual report pursuant to section 15 (d) of the
  Securities Exchange Act of 1934) that is incorporated by reference in the
  registration statement shall be deemed to be a new registration statement
  relating to the securities offered therein, and the offering of such
  securities at that time shall be deemed to be the initial bona fide
  offering thereof.
 
    (c) (1) The undersigned Registrant hereby undertakes as follows: that
  prior to any public reoffering of the securities registered hereunder
  through use of a prospectus which is a part of this registration statement,
  by any person or party who is deemed to be an underwriter within the
  meaning of Rule 145 (c), the issuer undertakes that such reoffering
  prospectus will contain the information called for by the applicable
  registration form with respect to reofferings by persons who may be deemed
  underwriters, in addition to the information called for by the other items
  of the applicable form.
 
                                     II-3
<PAGE>
 
    (2) The Registrant undertakes that every prospectus: (i) that is filed
  pursuant to the paragraph (1) immediately preceding, or (ii) that purports
  to meet the requirements of Section 10 (a) (3) of the Act and is used in
  connection with an offering of securities subject to Rule 415, will be
  filed as a part of an amendment to the registration statement and will not
  be used until such amendment is effective, and that, for purposes 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.
 
    (d) 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.
 
    (e) The undersigned Registrant hereby undertakes to respond to requests
  for information that is incorporated by reference into the prospectus
  pursuant to Item 4, 10(b), 11, or 13 of this Form S-4, within one business
  day of receipt of such request, and to send the incorporated documents by
  first class mail or other equally prompt means. This includes information
  contained in documents filed subsequent to the effective date of the
  registration statement through the date of responding to the request.
 
    (f) 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 became effective.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
  We have audited in accordance with generally accepted auditing standards,
the consolidated and combined financial statements of Metromail Corporation
and Affiliates included in this registration statement and have issued our
report thereon dated January 21, 1997. Our audit was made for the purpose of
forming an opinion on the basic financial statements as a whole. The schedule
immediately following this report is presented for purposes of complying with
the Securities and Exchange Commissions rules and is not part of the basic
financial statements. This schedule has been subjected to the auditing
procedures applied in the audit of the basic financial statements and, in our
opinion, fairly states in all material respects the financial data required to
be set forth therein in relation to the basic financial statements taken as a
whole.

Metromail Corporation
360 East 22nd Street
Lombard, Illinois  60148

Ladies and Gentlemen:

          We refer to the Agreement and Plan of Merger dated as of May 17, 1997
(the "Agreement") among Metromail Corporation, a Delaware corporation
("Parent"), MML Merging Company, a Colorado corporation and a direct wholly-
owned subsidiary of Parent ("Mergerco"), and Atlantes Corporation, a Colorado
corporation (the "Company"), which provides for the merger (the "Merger") of
Mergerco with and into the Company on the terms and conditions therein set
forth, the time at which the Merger becomes effective being hereinafter referred
to as the "Effective Time." Capitalized terms not defined herein have the
meanings specified in the Agreement.

          As provided in the Agreement, at the Effective Time, by reason of the
Merger:  (i) all outstanding shares of Company Common Stock then held in the
treasury of the Company will be canceled, and no capital stock of Parent, cash
or other consideration will be delivered in exchange therefor; (ii) each then
outstanding share of capital stock of Mergerco will be converted into one fully
paid and nonassessable share of Common Stock, no par value per share, of the
Company, as the Surviving Corporation; and  (iii) subject to the right of
holders of Company Common Stock to dissent from the Merger, each then
outstanding share of Company Common Stock, each then outstanding Company
Warrant, and each then outstanding Company Stock Option will be converted into a
specified number of shares of Parent Common Stock (or, if elected by a holder
thereof and subject to certain limitations, into a specified amount of cash)
plus additional shares of Parent Common Stock on a deferred, contingent basis,
all as more fully set forth in the Agreement.  Cash will be paid in lieu of
fractional shares of Parent Common Stock.

          Under Section 2.4 of the Agreement, the number of shares of Company
Common Stock to be converted in the Merger into the right to receive cash is
subject to a limitation that depends, in part, on an amount Parent estimates to
be payable to holders of Dissenting Shares. For purposes of this opinion we have
assumed, with your consent, that Parent's estimate of the amount to be payable
to holders of Dissenting Shares will equal the amount actually required to be so
paid.

          For purposes of this opinion we have also assumed, with your consent,
as follows:
<PAGE>
 
          1. There is no plan or intention on the part of the shareholders of
     the Company to sell, exchange or otherwise dispose of a number of shares of
     Parent Common Stock (including, without limitation, Contingent Shares) to
     be received in the Merger in exchange for Company Common Stock that would
     reduce the Company shareholders' ownership of Parent Common Stock so
     received (or to be received) to a number of shares having a value,
     excluding the value of Parent Common Stock treated as having been received
     as interest, as of the Effective Time, of less than 50% of the value of all
     of the formerly outstanding shares of Company Common Stock outstanding
     immediately prior to the Effective Time. For the purposes of the preceding
     sentence, (i) all shares of Company Common Stock which are to be (a)
     exchanged for cash or other property as a part of the Merger, (b)
     surrendered by Company shareholders exercising dissenters' rights or (c)
     exchanged for cash in lieu of fractional shares of Parent Common Stock are,
     in each case, treated as outstanding shares of Company Common Stock
     immediately prior to the Effective Time. Furthermore, all shares of Company
     Common Stock held by Company shareholders and all shares of Parent Common
     Stock (including, without limitation, Contingent Shares) which are to be
     received by holders of Company Common Stock in the Merger that, as to all
     such shares, have been or will be sold, redeemed or disposed of, either
     prior or subsequent to the Effective Time pursuant to any overall plan of
     which the Merger is a part, will be considered for purposes of the first
     sentence of this paragraph 1. Notwithstanding the foregoing, CVM Equity
     Fund III, Ltd., CVM Equity Fund IV, Ltd., LM Partnership II, CBJ
     Partnership, LLGM Partnership and Wolf Venture I, LLC, each of which is a
     partnership for federal income tax purposes and a holder of Company Common
     Stock, plans to distribute the shares of Parent Common Stock received in
     the Merger to its partners in accordance with their interests in each such
     partnership. For purposes of this paragraph 1, the partners of each such
     partnership will be treated as holders of Company Common Stock prior to the
     Effective Time and of Parent Common Stock thereafter (by reason of holding
     an indirect interest in such Stock through such a partnership or by reason
     of holding a direct interest in Parent Common Stock upon any such
     distribution).

          2. There is no plan or intention on the part of those holding Company
     Warrants to sell, exchange or otherwise dispose of a number of shares of
     Parent Common Stock (including, without limitation, Contingent Shares) to
     be received in the Merger in exchange for Company Warrants that would
     reduce the Company Warrant holders' ownership of Parent Common Stock so
     received (or to be received) to a number of shares having a value,
     excluding the value of Parent Common Stock treated as having been received
     as interest, as of the Effective Time, of less than 50% of the value of all
     of the formerly outstanding Company Warrants immediately prior to the
     Effective Time. For the purposes of the preceding sentence all Company
     Warrants which are to be exchanged for cash or other property as a part of
     the Merger, or exchanged for cash in lieu of fractional shares of Parent
     Common Stock, are treated as outstanding Company Warrants immediately prior
     to the Effective Time. Furthermore, all Company Warrants, and all shares of
     Parent Common Stock (including, without limitation, Contingent Shares)
     which are to be received in exchange for Company Warrants in the Merger,
     that, as to all such Company Warrants and shares, have been or will be
     sold, redeemed or disposed of (in all cases other than through an exercise
     of a Company Warrant) either prior or subsequent to the Effective Time
     pursuant to any overall plan of which the Merger is a part will be
     considered for purposes of the first sentence of this paragraph 2.
     Notwithstanding the foregoing, CVM Equity Fund III, Ltd.,

                                      -2-
<PAGE>
 
     CVM Equity Fund IV, Ltd., LM Partnership II, CBJ Partnership and LLGM
     Partnership, each of which is a partnership for federal income tax purposes
     and a holder of Company Warrants, plans to distribute the shares of Parent
     Warrants received in the Merger to its partners in accordance with their
     interests in each such partnership. For purposes of this paragraph 2, the
     partners of each such partnership will be treated as holders of Company
     Warrants prior to the Effective Time and of Parent Common Stock thereafter
     (by reason of holding an indirect interest in Company Warrants or Parent 
     Common Stock through such a partnership or by reason of holding a direct 
     interest in Parent Common Stock upon any such distribution).


          The Merger and the Agreement are more fully described in Parent's
Registration Statement on Form S-4 (the "Registration Statement") relating to
the registration of shares of Parent Common Stock to which this opinion is an
exhibit, which is being filed by Parent with the Securities and Exchange
Commission pursuant to the Securities Act of l933, as amended. The Registration
Statement includes the Proxy Statement/Prospectus (the "Prospectus") of Parent
and the Company.

          In rendering the opinions expressed below, we have relied upon the
accuracy of the facts, information and representations and the completeness of
the covenants contained in the Agreement, the Prospectus and such other
documents as we have deemed relevant and necessary. Such opinions are
conditioned, among other things, not only upon such accuracy and completeness as
of the date hereof, but also the continuing accuracy and completeness thereof as
of the Effective Time. Moreover, we have assumed the absence of any change to
any of such instruments between the date hereof and the Effective Time.

          In addition to the assumptions set out above, we have also assumed the
authenticity of all documents submitted to us as originals, the genuineness of
all signatures, the legal capacity of all natural persons and the conformity
with original documents of all copies submitted to us for our examination. We
have further assumed that: (i) the transactions related to the Merger or
contemplated by the Agreement will be consummated (A) in accordance with the
Agreement and (B) as described in the Prospectus; (ii) the Merger will qualify
as a statutory merger under the laws of the State of Colorado; and (iii) as of
the date hereof, and as of the Effective Time (as if made as of the Effective
Time), the written statements made by executives of Parent and the Company
contained in the Parent Tax Certificate and the Company Tax Certificate,
respectively, are and will be accurate in all respects.

          In rendering the opinions expressed below, we have considered the
applicable provisions of the Internal Revenue Code of 1986, as amended (the
"Code"), Regulations promulgated thereunder by the United States Treasury
Department (the "Regulations"), pertinent judicial authorities, rulings of the
Internal Revenue Service and such other authorities as we have considered
relevant. It should be noted that the Code, the Regulations and such judicial
decisions, administrative interpretations and other authorities are subject to
change at any time and, in some circumstances, with retroactive effect; and any
such change could affect the opinions stated herein.

                                      -3-
<PAGE>
 
          Based upon and subject to the foregoing, it is our opinion, as counsel
for Parent, that:

          (i) The Merger will constitute a "reorganization" within the meaning
     of Section 368(a) of the Code, and the Company, Mergerco and Parent will
     each be a party to such reorganization within the meaning of Section 368(b)
     of the Code;

          (ii) No gain or loss will be recognized by Parent or the Company as a
     result of the Merger;

          (iii) No income, gain or loss will be recognized by the shareholders
     of the Company upon the exchange of their Company Common Stock for shares
     of Parent Common Stock or cash (or a combination thereof) pursuant to the
     Merger, except that gain realized on such exchange will be recognized to
     the extent of cash received (excluding cash, if any, received in lieu of
     fractional shares of Parent Common Stock), gain or loss will be recognized
     with respect to cash, if any, received in lieu of fractional shares of
     Parent Common Stock and income will be recognized to the extent of any
     amount treated as interest;

          (iv) The aggregate tax basis of the shares of Parent Common Stock
     received in exchange for Company Common Stock pursuant to the Merger
     (including fractional shares of Parent Common Stock for which cash is
     received) will be the same as the aggregate tax basis of the Company Common
     Stock exchanged therefor, reduced by the amount of cash received in such
     exchange (excluding cash, if any, received in lieu of fractional shares of
     Parent Common Stock), increased by any gain recognized by reason of the
     receipt of such cash in such exchange, and increased by any amount treated
     as interest;

          (v) Except to the extent of Parent Common Stock treated as interest,
     the holding period for shares of Parent Common Stock received in exchange
     for Company Common Stock pursuant to the Merger will include the holding
     period of the Company Common Stock exchanged therefor, provided such
     Company Common Stock was held as a capital asset by the shareholder at the
     Effective Time; and

          (vi) A shareholder of the Company who receives cash in lieu of a
     fractional share of Parent Common Stock will recognize gain or loss equal
     to the difference, if any, between such shareholder's tax basis in such
     fractional share (as described in clause (iv) above) and the amount of cash
     received.

          Based solely upon and subject to the foregoing, it is also our opinion
that the statements under the caption "THE MERGER--Certain Material Federal
Income Tax

                                      -4-
<PAGE>
 
Consequences" in the Prospectus, to the extent that they constitute matters of
law or legal conclusions, are correct in all material respects.

          Except as expressly set forth in paragraphs (i) through (vi),
inclusive, and in the preceding paragraph, you have not requested, and we do not
herein express, any opinion concerning the tax consequences of, or any other
matters related to, the Merger.

          We assume no obligation to update or supplement this letter to reflect
any facts or circumstances which may hereafter come to our attention with
respect to the opinions expressed above, including any changes in applicable law
which may hereafter occur.

          We hereby consent to the filing of this letter as an exhibit to the
Registration Statement and to all references to our Firm included in or made a
part of the Registration Statement.

                                    Very truly yours,

  Pursuant to the Merger Agreement, the number of Shares and Warrants to be
converted into the right to receive cash in the Merger is subject to certain
limitations. No assurance can be given that a Cash Election by any given
shareholder or Warrant holder, including this Cash Election by the
undersigned, can be accommodated. Rather, the Cash Election by each holder of
Shares or Warrants, including this Election by the undersigned, will be
subject to the results of the election and allocation procedures set forth in
the Merger Agreement and described in the Proxy Statement/Prospectus. There is
no limitation on the number of Options for which a Cash Election may be made.
See "The Merger Agreement--Cash Election" in the accompanying Proxy
Statement/Prospectus for a more detailed description of the Cash Election.
 
  Holders of Shares, Warrants and/or Options who wish to exercise the Cash
Election with respect to all or a portion of their Shares, Warrants and/or
Options must complete this Form of Election, copies of which have been mailed,
together with the Proxy Statement/Prospectus, to shareholders of record on the
Atlantes Record Date (as defined in the Proxy Statement/Prospectus) and to
holders of Warrants and Options whose names are registered on the books and
records of Atlantes. A Cash Election shall have been properly made only if the
Exchange Agent shall have received, by 5:00 P.M. New York time, on the
Election Date, a Form of Election properly completed and signed and
accompanied by the stock certificates, warrant certificates or stock option
agreements representing the Shares, Warrants and/or Options as to which the
Form of Election relates. Holders who do not make the Cash Election or do not
comply with the Cash Election procedure set forth in the Proxy
Statement/Prospectus and this Form of Election will receive Metromail Common
Stock and will not receive any cash in the Merger (other than cash in lieu of
fractional shares of Metromail Common Stock).
 
  EACH HOLDER OF SHARES, WARRANTS AND/OR OPTIONS IS STRONGLY ENCOURAGED TO
READ THE PROXY STATEMENT/PROSPECTUS IN ITS ENTIRETY AND TO DISCUSS THE
CONTENTS THEREOF, THE MERGER AND THIS FORM OF ELECTION WITH SUCH HOLDER'S
PERSONAL FINANCIAL AND TAX ADVISORS PRIOR TO DECIDING WHETHER TO MAKE A CASH

NUMBER OF FACTORS. FOR CERTAIN INFORMATION REGARDING THE FEDERAL INCOME TAX

carefully the instructions regarding completion of this Form of Election set
forth below. If you have any questions concerning this Form of Election or
require any information or assistance, see Instruction 11.
 
  ANY HOLDER OF SHARES, WARRANTS AND/OR OPTIONS WHO INTENDS TO RECEIVE ONLY
METROMAIL COMMON STOCK IN THE MERGER SHOULD NOT SUBMIT THIS FORM OF ELECTION

                                       5
<PAGE>
 
  1. Delivery of Form of Election. This Form of Election is to be used to make
the Cash Election. A properly completed and duly executed Form of Election,
and any other documents required by this form, must be received by the
Exchange Agent at its address set forth above on or prior to the Election
Date. No alternative, conditional or contingent Cash Elections are permitted.
 
  THE METHOD OF DELIVERY OF THIS FORM AND ALL OTHER REQUIRED DOCUMENTS IS AT
THE ELECTION AND RISK OF THE HOLDER OF SHARES, WARRANTS AND/OR OPTIONS. IF
THIS FORM IS SENT BY MAIL, CERTIFIED MAIL WITH RETURN RECEIPT REQUESTED IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY TO THE EXCHANGE AGENT.
 
  2. Inadequate Space. If the space provided herein is inadequate, list and
attach hereto on a separate schedule, the information requested with respect
to Shares, Warrants and/or Options subject to a Cash Election.
 
  3. Signatures on Form of Election. If this Form of Election is signed by the
registered holder of the Shares, Warrants and/or Options, the signature must
correspond with the name as written on the face of the certificates for Shares
and/or Warrants and on the stock option agreement for Options without
alteration, enlargement or any change whatsoever. If any of the Shares,
Warrants and/or Options subject to a Cash Election are owned of record by two
or more joint owners, all such owners must sign this form.
 
  If any of the Shares, Warrants and/or Options subject to a Cash Election are
registered in different names, it will be necessary to complete, sign and
submit as many separate Forms of Election as there are different
registrations.
 
  If this Form of Election is 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 Atlantes and Metromail, proper evidence
satisfactory to Atlantes and Metromail of their authority so to act must be
submitted.
 
  4. Irregularities and Waiver of Conditions. All questions as to the
validity, form and eligibility (including time of receipt) of any Cash
Election will be determined by Metromail and Atlantes, in their sole
discretion, which determination shall be final and binding. Metromail and
Atlantes reserve the absolute right to reject any Cash Election determined by
them not to be in proper form, or the acceptance of which may, in the opinion
of their respective counsel, be unlawful. Metromail and Atlantes also reserve
the absolute right to waive any defect or irregularity in any Cash Election
with respect to any particular Shares, Warrants and/or Options or any
particular holder, and such interpretations of the terms and conditions of the
Cash Election (including these instructions) shall be final and binding.
Unless waived, any defects or irregularities in connection with a Cash
Election must be cured within such time as Metromail and Atlantes shall
determine. None of Metromail, Atlantes or any other person will be under any
duty or obligation to give notice of any defects or irregularities in Cash
Elections, nor shall any of them incur any liability for failure to give such
notice.
 
  5. Change or Revocation of Election. Any holder may at any time prior to the
Election Date change such holder's election by written notice received by the
Exchange Agent at or prior to the Election Date and accompanied by a properly
completed Form of Election. Metromail and Atlantes have the right in their
sole discretion and by mutual agreement to permit changes in Cash Elections
after the Election Date. Any holder may at any time prior to the Election Date
revoke such holder's election by written notice received by the Exchange Agent
at or prior to the Election Date or by withdrawal prior to the Election Date
of any stock certificates, warrant certificates or stock option agreements
previously deposited with the Exchange Agent. Any revocation of an election
may be withdrawn by notice of such withdrawal delivered at or prior to the
Election Date. Any holder who shall have deposited any stock certificates,
warrant certificates or stock option agreements with the Exchange Agent shall
again have the right to withdraw such stock certificates, warrant certificates
or stock option agreements by written notice received by the Exchange Agent
and thereby revoke such holder's
 
                                       6
<PAGE>
 
election as of the Election Date at any time after the expiration of the
period of 60 days following the Election Date if the Merger shall not have
been consummated prior thereto.
 
  6. Lost Certificates. If you are not able to locate your stock certificates,
warrant certificates or stock option agreements, you should contact Atlantes,
at 90 Madison Street, Denver, Colorado 80206. In such event, Atlantes will
forward additional documentation for you to complete in order to effectively
deposit such lost or destroyed certificate(s) or agreements.
 
  7. Stock Transfer Taxes. If payment of the cash to be received in the Merger
or the certificate for shares of Metromail Common Stock are to be issued in
the name of any person other than the registered holder(s), then the amount of
any transfer taxes (whether imposed on the registered holder(s), such other
person or otherwise) payable on account of the transfer to such person will be
deducted from the purchase price unless satisfactory evidence of the payment
of such taxes, or exemption therefrom, is submitted.
 
  Except as provided in this Instruction 7, it will not be necessary for
transfer tax stamps to be affixed to the certificates listed in this Form of
Election.
 
  8. Special Payment Instructions. If the check for the cash to be received in
the Merger or the certificate for shares of Metromail Common Stock are to be
issued in the name of someone other than the registered holder(s) of the
Shares, Warrants and/or Options, you must follow the guidelines below. Note
that in each circumstance listed below, holders must have signatures
guaranteed and complete Box 6.
 
  (a) Endorsement and Guaranty. The certificate(s) for such Shares must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name(s) of the registered holder(s) appear(s) on the
certificate for such Shares. Warrant certificates and stock option agreements
must be accompanied by evidence of due transfer, in each case to the person
who is to receive the cash and/or Metromail Common Stock. The signature(s) of
the registered holder(s) on any such certificates, stock powers or other
documents must correspond with the name(s) written upon the face of the
certificate(s) or agreements in every particular and must be guaranteed by an
Eligible Guarantor Institution as defined below.
 
                 DEFINITION OF ELIGIBLE GUARANTOR INSTITUTION
 
  Generally, an Eligible Guarantor Institution, as defined in Rule 17Ad-15
promulgated by the Securities and Exchange Commission under the Securities
Exchange Act of 1934, as amended, means:
 
    1) Banks as defined in Section 3(a) of the Federal Deposit Insurance Act.
 
    2) Brokers, dealers, municipal securities dealers, municipal securities
  brokers, government securities dealers and government securities brokers,
  as those are defined under the Exchange Act.
 
    3) Credit unions (as that term is defined in Section 19 (b)(1)(A) of the
  Federal Reserve Act).
 
    4) National securities exchanges, registered securities associations and
  clearing agencies, as those terms are used under the Exchange Act.
 
    5) Savings associations (as that term is defined in Section 3(b) of the
  Federal Deposit Insurance Act).
 
  (b) Transferee's Signature. The Form of Election must be signed by the
transferee or assignee, or such person's agent, and should not be signed by
the transferor or assignor. The signature of such transferee or assignee must
be guaranteed by an Eligible Guarantor Institution as provided in Instruction
8(a).
 
  (c) Correction of or Change in Name. For a correction of name or for a
change in name which does not involve a change in ownership, proceed as
follows: For a change in name by marriage, the Form of Election should be
signed, for example, "Mary Doe, now by marriage Mary Jones." For a correction
in name, the Form of Election should be signed, for example, "James E. Brown,
incorrectly inscribed as J. E. Brown." The
 
                                       7
<PAGE>
 
signature in each case should be guaranteed in the manner described in
Instruction 8(a) above and the holder should complete Box 6.
 
  9. Special Instructions for Delivery by the Exchange Agent. The check for
the cash to be received in the Merger and the certificates for shares of
Metromail Common Stock will be mailed to the address set forth in Box 4 unless
instructions to the contrary are given in Box 7 entitled "Special Delivery
Instructions."
 
  10. Substitute Form W-9. Holders of Shares, Warrants and/or Options are
required to provide the Exchange Agent with such holder's correct Taxpayer
Identification Number ("TIN") on Substitute Form W-9, which is provided below,
unless an exemption applies. Failure to provide the information on the
Substitute Form W-9 may subject the holder to a $50 penalty and to 31% federal
income tax backup withholding on the payment of the cash and/or shares of
Metromail Common Stock to be received in the Merger.
 
  11. Requests for Assistance or Additional Copies. Requests for information
or additional copies of this Form of Election or the Proxy
Statement/Prospectus should be directed to the Exchange Agent at American
Stock Transfer and Trust Company, 40 Wall Street, 46th Floor, New York, New
York 10005.
 
                           IMPORTANT TAX INFORMATION
 
  Under federal income tax law, holders of Shares, Warrants and/or Options are
required to provide the Exchange Agent with such holder's correct TIN on the
Substitute Form W-9. If such holder is an individual, the TIN is such holder's
Social Security Number. If the Exchange Agent is not provided with the correct
TIN, the holder may be subject to a $50 penalty imposed by the Internal
Revenue Service. In addition, payments that are made to such holder with
respect to Shares, Warrants and/or Options converted in the Merger may be
subject to backup withholding.
 
  Certain holders (including, among others, generally all corporations and
certain foreign individuals) are not subject to these backup withholding and
reporting requirements. In order for a foreign individual to qualify as an
exempt recipient, that holder must submit a statement, signed under penalties
of perjury, attesting to that individual's exempt status. Such statements may
be obtained from the Exchange Agent. All exempt recipients (including foreign
persons wishing to qualify as exempt recipients) should see the enclosed
Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9 for additional instructions.
 
  If backup withholding applies, the Exchange Agent is required to withhold
31% of any payments made to the holder. Backup withholding is not an
additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If backup
withholding results in an overpayment of taxes, a refund may be obtained.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
  To prevent backup federal income tax withholding on payments that are made
to a holder with respect to Shares, Warrants and/or Options converted in the
Merger, the holder is required to notify the Exchange Agent of such holder's
correct TIN by completing the form certifying that the TIN provided on the
Substitute Form W-9 is correct.
 
WHAT NUMBER TO GIVE THE EXCHANGE AGENT
 
  The holder is required to give the Exchange Agent the Social Security Number
or Employer Identification Number of the record owner of the Shares, Warrants
and/or Option. If the Shares, Warrants and/or Option are 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 guidelines on which number to report.
